Innovative soil fluoride estimation method: dual polarimetric saline-associated fluoride for agricultural patches.

Fluoride and its constituents in soil affect plant growth and public health. In this study, soil fluoride was measured for the semi-arid regions in southern India, using Sentinel-1 data in conjunction with the dual polarimetric saline-associated fluoride model (also known as fluoride model). A loss angle was estimated from laboratory-based dielectric components of soil samples with strong electrical conductivity under high and low fluoride conditions. The conductivity loss angle and real and imaginary dielectric constants were used to study fluoride salt's dielectric behavior. The imaginary dielectric component sensitive to dielectric loss could predict fluoride across large areas over time. This was statistically analyzed with R2 = 0.86, RMSE = 1.90, and bias = 0.35 showing a promising depiction that C-band SAR data can distinguish fluoride levels over varied clay soil and soil with varying vegetation development. Moreover, the association between biomass and simulated fluoride helped to identify fluoride-tolerant and non-tolerant crops. The study found that Sorghum and Oryza sativa tolerate saline-associated fluoride, whereas Peanut and Allium do not. Furthermore, the model successfully retrieves fluoride from saline salts based on tangent loss.

On the Role of Speech In Psychoanalysis: Revisiting Lacan's "Function and Field".

A number of underutilized concepts in Lacan's "Function and Field of Language and Speech in Psychoanalysis" are examined with an eye to rendering them accessible and practicable to analysts from outside the Lacanian tradition. The concepts of empty and full speech are discussed, along with the notions of the subject of the unconscious, and speaking as itself a mode of intersubjectivity. Attention is afforded the future-oriented mode of psychic temporality that Lacan argues pertains to psychoanalytic practice (that of the future anterior tense, the standpoint from which analysands situate themselves in respect of what they "will have been"). These concepts are then linked to technical initiatives-such as punctuation (the "editorial" role the analyst plays in reference to the analysand's speech) and scansion (the use of suspension, interruption, or cutting to highlight facets of that speech). These techniques can be read as extensions of Freud's fundamental rule of free association insofar as they aim to disrupt defensive ego narratives, engage unconscious processes, and draw analysands' attention, in a potentially transformative manner, to their speech and what it does.

The role of imaginary companion in the life of only children: a qualitative study.

INTRODUCTION: An imaginary companion is an invisible or personified entity created by children for themselves. An imaginary companion typically serves as a companion to the child and plays a significant role in their life, especially for only children who may experience more loneliness compared to other children. This research was conducted to investigate the role of an imaginary companion in the lives of only children. METHOD: The present study was conducted using a qualitative method and a content analysis approach. Through purposeful sampling, a total of 34 preschool and primary school children, aged 6 to 9 years, from schools in Mashhad city, were selected until saturation was reached. They were subjected to semi-structured interviews. After data collection, the data were coded, and then the main and sub-themes were extracted. RESULTS: The research findings were represented in the form of 196 statements, 28 sub-themes, and 9 main themes. The main themes included the role of an imaginary companion in alleviating loneliness, the role of an imaginary companion in amusement, the role of an imaginary companion in emotional regulation, conversations with an imaginary companion, guidance from an imaginary companion for good and bad behaviors, the assistance of an imaginary companion in tasks, helping to generate new scenarios, the advantages of having an imaginary companion, and the disadvantages of having one. CONCLUSION: Based on the aforementioned findings, it can be concluded that the presence of an imaginary companion can not only support children but also promote creativity and distance them from the virtual space and realities of the real world. Parental awareness of this matter can aid in the child's growth, fulfill their needs, and, on the other hand, prevent potential harm to children.

Spectral induced polarization signatures of smoldering remediation enhanced with colloidal activated carbon: An experimental study.

Monitoring the remediation of soil and groundwater contaminated by organic compounds remains highly challenging. Thermal treatments, such as smoldering combustion, have become established remediation techniques for destroying contaminants. Smoldering combustion can now be supported by colloidal activated carbon (CAC), with CAC being able to both adsorb contaminants and supplement the fuel source for destroying them. Despite this potential, effective performance monitoring of smoldering remediation remains limited. The objective of this study is to investigate the potential of the spectral induced polarization (SIP) geoelectrical technique to assess the performance of smoldering remediation of soils supplemented with CAC. SIP column experiments were first conducted to assess the response of SIP (i.e., real and imaginary components of the complex electrical conductivity) to varying concentrations of CAC in imitated field soils that contain, or do not contain, organic matter (OM). Results demonstrate that increasing OM and CAC contents increase both the real and imaginary conductivities, with the imaginary conductivity also showing frequency dependence. Smoldering and SIP column experiments were then conducted to assess the effectiveness of SIP for detecting changes in soils of varying OM and CAC contents that have been remediated by smoldering. Examination of the soils before and after smoldering indicates that SIP can track the evolving real conductivity and imaginary conductivity (in particular) between different soil compositions and different stages of the remedial process. High resolution scanning electron microscopy imaging was performed on all samples to validate the SIP and smoldering experiments, confirming significant reductions in carbon after smoldering. Overall, this study suggests that SIP has potential to track changes associated with the addition of remedial fluids like CAC in the subsurface, and the destruction of contaminants adsorbed to CAC by smoldering combustion.

Post-Menopausal Quality of Life Claims: Overlooking the Requirements of Normal Science and Fundamental Measurement in ICER'S Cost-Effectiveness Assessment of Fezolinetant for Moderate to Severe Vasomotor Symptoms.

One of the signal failures in health technology assessment is the absence of consideration given, not only to the standards of normal science, but to those of fundamental measurement. A recent evidence report by the Institute for Clinical and Economic Review (ICER) is emblematic of this failure. Based on a simple linear regression model that translates aggregate scores from the ordinal Menopause-specific Quality of Life Questionnaire (MENQOL) to the ordinal EuroQol EQ-5D-5L, ICER has applied these scores to an assumption driven model simulation to produce preferences, QALYs and incremental cost-per-QALY claims for fezolinetant for moderate to severe symptoms associated with menopause. Unfortunately, the attempt to crosswalk multidimensional or multiattribute ordinal scores is mathematically impossible. The 'created' EQ-5D-5L preferences are, as a result, of no interest. The overall result is that the ICER modelled claims for cost-effectiveness fail the required standards for normal science and fundamental measurement. fundamental are impossible. This is unfortunate, although it might be possible to assess certain domains of the MENQOL for their approximation to an interval score with the application of the Rasch Rating Scale Model, this will not support quality of life claims. A preferred approach would be to consider an alternative latent trait for quality of life in menopause, applying Rasch Measurement Theory (RMT), to develop a polytomous instrument that has the required measurement properties. The purpose of this commentary is to point out, as a number of previous commentaries have done, that this framework for creating assumption driven simulated modelled claims has no role in decisions for product assessment, access to formulary and pricing. This commentary expands upon these previous commentaries in placing RMT is the context of a needed paradigm shift to support the evolution of objective knowledge. This is critical if we are to understand, from the individual's perspective, not only an accurate assessment of the burden of menopause but to see this as part of an on-going research program that has to rely on fundamental measurement.

The Fourth Age in Prospect.

OBJECTIVES: Higgs and Gilleard (2015) have uniquely theorized the fourth age as a "social imaginary" of deep old age that blends notions of frailty, abjection, and the moral relations of care. This report evaluates the coherence and reach of the fourth-age imaginary among older adults in relative good health. METHODS: In a qualitative design and within samples at 5 sites (in Czechia, Germany, Hong Kong, Taiwan, and the United States), 138 adults aged 70+ and still living independently discussed what it would mean to be "not independent" in later life. Replies referenced other people in general, specific people, and one's own actual or potential experience. RESULTS: Pooled across sites, the views of our participants confirm the theorized features of the social imaginary. Participants spoke readily of gateway infirmities heralding frailty and of frailty's abjection; expressed dread and abhorrence of dependence, some saying that death would be preferable; and were anxious about nursing homes and about burdening others with an obligation to care for them. DISCUSSION: The bleak but formidable reputation of the fourth age impinges on those living in the third. The consonant expression of fourth-age features among older adults on 3 continents supports Gilleard and Higgs's claim that the fourth-age imaginary "contains a universal ontological quality" owing to human corporeality and the senescence to which it is subject. Fourth-age studies that document the lived experience of frailty and dependence have the potential to undermine the imaginary and furnish new narratives for facing the future.

Developing A Mobile App With a Human-Centered Design Lens to Improve Access to Mental Health Care (Mentallys Project): Protocol for an Initial Co-Design Process.

BACKGROUND: Co-design is one of the human-centered design approaches that allows end users to significantly and positively impact the design of mental health technologies. It is a promising approach to foster user acceptance and engagement in digital mental health solutions. Surprisingly, there is a lack of understanding of what co-design is in this field. In this paper, co-design is approached as a cocreation process involving persons with a lived experience of mental health problems, health professionals, and design experts who lead and facilitate the overall creative process. OBJECTIVE: This paper describes an initial co-design research protocol for the development of a mobile app that aims to improve access to mental health care. It highlights the characteristics of a co-design approach in e-mental health rooted in human-centered design and led by design experts alongside health experts. The paper focuses on the first steps (phase 1) of the co-design process of the ongoing Mentallys project. METHODS: This Mentallys project will be located in Montréal (Quebec, Canada). The method approach will be based on the "method stories," depicting the "making of" this project and reflecting adjustments needed to the protocol throughout the project in specific situations. Phase 1 of the process will focus on the desirability of the app. Targeted participants will include people with a lived experience of mental health problems, peer support workers and clinicians, and 3 facilitators (all design experts or researchers). Web-based sessions will be organized because of the COVID-19 pandemic, using Miro (RealtimeBoard Inc) and Zoom (Zoom Video Communications, Inc). Data collection will be based on the comments, thoughts, and new ideas of participants around the imaginary prototypes. Thematic analysis will be carried out after each session to inform a new version of the prototype. RESULTS: We conducted 2 stages in phase 1 of the process. During stage 1, we explored ideas through group co-design workshops (divergent thinking). Six co-design workshops were held: 2 with only clinicians (n=7), 2 with peer support workers (n=5) and people with a lived experience of mental health problems (n=2), and 2 with all of them (n=14). A total of 6 facilitators participated in conducting activities in subgroups. During stage 2, ideas were refined through 10 dyad co-design sessions (convergent thinking). Stage 2 involved 3 participants (n=3) and 1 facilitator. Thematic analysis was performed after stage 1, while analytic questioning is being performed for stage 2. Both stages allowed several iterations of the prototypes. CONCLUSIONS: The design of the co-design process, the leadership of the design expertise throughout the process, and the different forms of co-design activities are key elements in this project. We highly recommend that health researchers partner with professional designers or design researchers who are familiar with co-design.

Analysing the dynamic structure of warm dense matter in the imaginary-time domain: theoretical models and simulations.

Rigorous diagnostics of experiments with warm dense matter are notoriously difficult. A key method is X-ray Thomson scattering (XRTS), but the interpretation of XRTS measurements is usually based on theoretical models that entail various approximations. Recently, Dornheim et al. [Nat. Commun. 13, 7911 (2022)] introduced a new framework for temperature diagnostics of XRTS experiments that is based on imaginary-time correlation functions. On the one hand, switching from the frequency to the imaginary-time domain gives one direct access to a number of physical properties, which facilitates the extraction of the temperature of arbitrarily complex materials without relying on any models or approximations. On the other hand, the bulk of theoretical work in dynamic quantum many-body theory is devoted to the frequency domain, and, to the best of our knowledge, the manifestation of physics properties within the imaginary-time density-density correlation function (ITCF) remains poorly understood. In the present work, we aim to fill this gap by introducing a simple, semi-analytical model for the imaginary-time dependence of two-body correlations within the framework of imaginary-time path integrals. As a practical example, we compare our new model to extensive ab initio path integral Monte Carlo results for the ITCF of a uniform electron gas, and find excellent agreement over a broad range of wavenumbers, densities and temperatures. This article is part of the theme issue 'Dynamic and transient processes in warm dense matter'.

Portable deep-learning decoder for motor imaginary EEG signals based on a novel compact convolutional neural network incorporating spatial-attention mechanism.

Due to high computational requirements, deep-learning decoders for motor imaginary (MI) electroencephalography (EEG) signals are usually implemented on bulky and heavy computing devices that are inconvenient for physical actions. To date, the application of deep-learning techniques in independent portable brain-computer-interface (BCI) devices has not been extensively explored. In this study, we proposed a high-accuracy MI EEG decoder by incorporating spatial-attention mechanism into convolution neural network (CNN), and deployed it on fully integrated single-chip microcontroller unit (MCU). After the CNN model was trained on workstation computer using GigaDB MI datasets (52 subjects), its parameters were then extracted and converted to build deep-learning architecture interpreter on MCU. For comparison, EEG-Inception model was also trained using the same dataset, and was deployed on MCU. The results indicate that our deep-learning model can independently decode imaginary left-/right-hand motions. The mean accuracy of the proposed compact CNN reaches 96.75 ± 2.41% (8 channels: Frontocentral3 (FC3), FC4, Central1 (C1), C2, Central-Parietal1 (CP1), CP2, C3, and C4), versus 76.96 ± 19.08% of EEG-Inception (6 channels: FC3, FC4, C1, C2, CP1, and CP2). To the best of our knowledge, this is the first portable deep-learning decoder for MI EEG signals. The findings demonstrate high-accuracy deep-learning decoding of MI EEG in a portable mode, which has great implications for hand-disabled patients. Our portable system can be used for developing artificial-intelligent wearable BCI devices, as it is less computationally expensive and convenient for real-life application.

"Through the digits, through the fingers": Variations on the string figure as imaginary digital medium.

This article considers artistic engagements with string figure performance and collection as 'imaginary' articulations of digital media. As an object of anthropological inquiry, the string figure emerges in 1888 with a short paper by Franz Boas. Encouraged by more mainstream publications by Caroline Furness Jansen (2008) and Kathleen Haddon (1930), over the course of the 20th century the string figure would become a model through which largely western writers and artists have explored both the anxieties and dreams of ideal, embodied and networked communication technologies. The present article explores, specifically, the collecting projects and films of Harry Smith in the 1960s and 1970s; the video-performance piece of 1974, titled String Games: Improvisations for Inter-City Video, by the interdisciplinary artist Vera Frenkel; and the string figure exhibit at David Wilson's Museum of Jurassic Technology in Culver City, California. Through a media-archeological lens, the history of string figure fascination takes shape as a repository of dreams about (digital) communication, which, it is additionally suggested in a final section, might yet allow for the expansion and enlargement of conceptions of both digitality and media.

A New Option for Pain Prevention Using a Therapeutic Virtual Reality Solution for Bone Marrow Biopsy (REVEH Trial): Open-Label, Randomized, Multicenter, Phase 3 Study.

BACKGROUND: Evidence regarding the analgesic effect of distraction through immersion in virtual reality (VR) for care-induced pain has been documented in several phase 2 trials, but comparison with standard treatments in large, randomized studies is needed. OBJECTIVE: In this open-label, multicenter, randomized, phase 3 trial, we evaluated the safety and efficacy of a novel VR therapy solution for distraction in the context of bone marrow biopsy. METHODS: Bliss is a VR software with 4 imaginary interactive environments in 3 dimensions with binaural sound (head-mounted display). Efficacy regarding pain intensity was evaluated using a visual analog scale (VAS; score from 0 to 10) immediately after the biopsy. Secondary end points were anxiety and tolerance. Modified intention-to-treat analysis was performed. RESULTS: Overall, 126 patients with previously documented untreated or suspected malignant hemopathy between September 6, 2018, and May 18, 2020, were randomly assigned in a 1:1 ratio to receive pain prevention with a mixture of nitrous oxide/oxygen (MEOPA; n=63) or VR (n=63) before and during the bone marrow biopsy. We excluded 8 patients from the final analysis (3 in the MEOPA group and 5 in the VR group). All patients received local anesthesia (lidocaine) before biopsy. Follow-up was limited to 1 month after the biopsy. Participants' median age was 65.5 (range 18-87) years, and 54.2% (64/118) of patients were male. The average pain intensity was 3.5 (SD 2.6, 95% CI -1.6 to 8.6) for the MEOPA group and 3.0 (SD 2.4, 95% CI -1.7 to 7.7) for the VR group, without any significant differences in age, sex, center, and hemopathy (P=.26). Concerning anxiety, 67.5% (79/117; fear of pain questionnaire) of the patients were afraid before the biopsy, and anxiety scores were moderate to very high in 26.3% (30/114; revised Spielberger State-Trait Anxiety Inventory questionnaire) of the patients before the biopsy and 9.0% (10/114) after the biopsy for all patients, without a significant difference between the 2 groups (P=.83). Immersion in VR was well tolerated by the majority (54/57, 95%) of patients in the VR group. CONCLUSIONS: The intensity of pain did not significantly differ between both arms. VR was well tolerated, and the satisfaction of patients, nurses, and physicians was very high. VR could be an alternative treatment in case of contraindication or intolerance to MEOPA.

Targeted rhythmic visual stimulation at individual participants' intrinsic alpha frequency causes selective increase of occipitoparietal BOLD-fMRI and EEG functional connectivity.

Neural oscillations in distinct frequency bands are ubiquitous in the brain and play a role in many cognitive processes. The "communication by coherence" hypothesis, poses that the synchronization through phase coupling of frequency-specific neural oscillations regulate information flow across distribute brain regions. Specifically, the posterior alpha frequency band (7-12 Hz) is thought to gate bottom-up visual information flow by inhibition during visual processing. Evidence shows that increased alpha phase coherency positively correlates with functional connectivity in resting state connectivity networks, supporting alpha mediates neural communication through coherency. However, these findings have mainly been derived from spontaneous changes in the ongoing alpha rhythm. In this study, we experimentally modulate the alpha rhythm by targeting individuals' intrinsic alpha frequency with sustained rhythmic light to investigate alpha-mediated synchronous cortical activity in both EEG and fMRI. We hypothesize increased alpha coherency and fMRI connectivity should arise from modulation of the intrinsic alpha frequency (IAF) as opposed to control frequencies in the alpha range. Sustained rhythmic and arrhythmic stimulation at the IAF and at neighboring frequencies within the alpha band range (7-12 Hz) was implemented and assessed in a separate EEG and fMRI study. We observed increased cortical alpha phase coherency in the visual cortex during rhythmic stimulation at the IAF as in comparison to rhythmic stimulation of control frequencies. In the fMRI, we found increased functional connectivity for stimulation at the IAF in visual and parietal areas as compared to other rhythmic control frequencies by correlating time courses from a set of regions of interest for the different stimulation conditions and applying network-based statistics. This suggests that rhythmic stimulation at the IAF frequency induces a higher degree of synchronicity of neural activity across the occipital and parietal cortex, which supports the role of the alpha oscillation in gating information flow during visual processing.

Guided imaginary has been used in psychological intervention programs for the rehabilitation of injured athletes, since different studies associate it with an improvement in psychological coping and a reduction in anxiety due to the fear of being injured again. Therefore, the objective is to review the publications that use guided imaginary in the rehabilitation of injured athletes and determine its effectiveness. A systematic search was carried out following the PRISMA guide, in the Web of Science, using as keywords: sport injury*, psycho* and rehabilitation. The inclusion criteria were to be empirical and the application of guided imaginary in the rehabilitation of sports injury. 394 articles were acquired, which were reduced to 5. The results show that 4 works carried out guided imaginary together with other psychological techniques. Ad hoc evaluation instruments were used for the most part. Guided imaginary was shown to be affective in 4 of the 5 studies, achieving the desired effects. The most studied psychological variables were pain, adherence to rehabilitation, self-efficacy, motivation and anxiety. It follows that guided imaginary has been useful in the rehabilitation of sports injuries as part of a comprehensive treatment program for the injured athlete. (AU)

Autistic children who create imaginary companions: Evidence of social benefits.

LAY ABSTRACT: Research on neurotypical children with imaginary friends has found that those with imaginary friends have better social skills and are more able to think about how other people's minds work compared to children without imaginary friends. Research shows that some autistic children also create imaginary friends. This article is the first to look at whether or not autistic children with imaginary friends have stronger social skills and an improved ability to think about others' minds than those without imaginary friends. We asked parents to report about their children aged 5 to 12. Finding almost half reported their child had an imaginary friend, a much larger number than previous research with younger children. Our findings also suggested that autistic children with imaginary friends were better able to understand others' minds and had stronger social skills than their peers without imaginary friends. The children's language ability did not influence this. The findings of this study add to the evidence that with respect to the creation imaginary friends and their potential benefits, the play profiles of autistic children are similar to the general population. It also provides more evidence that the understanding of others' minds is not all or nothing in autism and gives reason for researchers to investigate whether the causes of these differences are the same or different for autistic children.

Neuronal networks underlying ictal and subclinical discharges in childhood absence epilepsy.

Childhood absence epilepsy (CAE), involves 3 Hz generalized spikes and waves discharges (GSWDs) on the electroencephalogram (EEG), associated with ictal discharges (seizures) with clinical symptoms and impairment of consciousness and subclinical discharges without any objective clinical symptoms or impairment of consciousness. This study aims to comparatively characterize neuronal networks underlying absence seizures and subclinical discharges, using source localization and functional connectivity (FC), to better understand the pathophysiological mechanism of these discharges. Routine EEG data from 12 CAE patients, consisting of 45 ictal and 42 subclinical discharges were selected. Source localization was performed using the exact low-resolution electromagnetic tomography (eLORETA) algorithm, followed by FC based on the imaginary part of coherency. FC based on the thalamus as the seed of interest showed significant differences between ictal and subclinical GSWDs (p < 0.05). For delta (1-3 Hz) and alpha bands (8-12 Hz), the thalamus displayed stronger connectivity towards other brain regions for ictal GSWDs as compared to subclinical GSWDs. For delta band, the thalamus was strongly connected to the posterior cingulate cortex (PCC), precuneus, angular gyrus, supramarginal gyrus, parietal superior, and occipital mid-region for ictal GSWDs. The strong connections of the thalamus with other brain regions that are important for consciousness, and with components of the default mode network (DMN) suggest the severe impairment of consciousness in ictal GSWDs. However, for subclinical discharges, weaker connectivity between the thalamus and these brain regions may suggest the prevention of impairment of consciousness. This may benefit future therapeutic targets and improve the management of CAE patients.

In a qualitative and bibliographical approach, it lists axes of erasure of indigenous identities (ethnogenocide). They are: the requirement for living on demarcated land; the indigenous language; the stereotypical appearance and the notions of "descendant" and "brown". 37 Final Papers from the Atlantic Forest Indigenous Degree Course, from the Federal University of Santa Catarina, authored by Guarani academics, were read. The central arguments of these works were emphasized, especially those relating to Guarani indigenous identity and whiteness. Through the Scielo Platform, an analysis of articles on whiteness, published between 2018 and 2022, was carried out. It revealed an erasure of indigenous issues. In Guarani works, the specificity of anti-indigenous racism were highlighted, grouped under the ethnogenocide category. The research conclusion points out the importance of indigenous cosmogonies and their temporalities as means of reforesting the imagination.

Embracing the cordillera: Luis Carranza Ayarza and the development of environmental imaginaries in late-nineteenth-century Peru / Abrazando la cordillera: Luis Carranza Ayarza y el desarrollo de los imaginarios ambientales en el Perú de fines del siglo XIX

Abstract This article examines the relationship between local scientific ideas about the natural world and the economic potential to transform the modern nation-state in Peru during the late nineteenth century. Writings by the Peruvian scientist Luis Carranza indicate how support for a distinctive environmental imaginary of the country's geography made it possible to conceptualize nature as an essential component of Peruvian identity. As a result, local scientists had to "imaginatively" reshape the nature of the Andes for modernization purposes. The social and political ramifications of these ideas in Carranza's work were key to the foundation of scientific institutions such as the Geographical Society of Lima.

Resumen Este artículo examina la relación entre las ideas científicas locales sobre el mundo natural y el potencial económico para transformar el Estado-nación moderno en el Perú a fines del siglo XIX. Los escritos del científico peruano Luis Carranza señalan cómo el apoyo a un imaginario ambiental distintivo de la geografía del país permitió conceptualizar la naturaleza como componente esencial de la identidad peruana. Como resultado, los científicos locales tuvieron que remodelar "imaginativamente" la naturaleza de los Andes con fines de modernización. Las ramificaciones sociales y políticas de estas ideas en la obra de Carranza fueron clave para la fundación de instituciones científicas como la Sociedad Geográfica de Lima.

A Review of Brain Activity and EEG-Based Brain-Computer Interfaces for Rehabilitation Application.

Patients with severe CNS injuries struggle primarily with their sensorimotor function and communication with the outside world. There is an urgent need for advanced neural rehabilitation and intelligent interaction technology to provide help for patients with nerve injuries. Recent studies have established the brain-computer interface (BCI) in order to provide patients with appropriate interaction methods or more intelligent rehabilitation training. This paper reviews the most recent research on brain-computer-interface-based non-invasive rehabilitation systems. Various endogenous and exogenous methods, advantages, limitations, and challenges are discussed and proposed. In addition, the paper discusses the communication between the various brain-computer interface modes used between severely paralyzed and locked patients and the surrounding environment, particularly the brain-computer interaction system utilizing exogenous (induced) EEG signals (such as P300 and SSVEP). This discussion reveals with an examination of the interface for collecting EEG signals, EEG components, and signal postprocessing. Furthermore, the paper describes the development of natural interaction strategies, with a focus on signal acquisition, data processing, pattern recognition algorithms, and control techniques.

Bouncing off Ove: Old men's readings of the novel A Man Called Ove as a cultural representation of ageing masculinity.

In recent years, there has been a rise in portrayals of greying protagonists in popular fiction, often featuring older people in humorous and heart-warming stories. An emerging genre within this literature is the "geezer and grump lit", a genre where older people are active protagonists, and while often portrayed as grumpy "'usually turn out to have a heart of gold'" (Swinnen, 2019). A notable example of a book in this genre is the internationally bestselling novel A Man Called Ove (2012) by the Swedish author Fredrik Backman. Telling the story of the 59-year-old Ove who sets out to take his own life, the novel can be understood not only as a cultural representation of ageing, but more specifically a cultural representation of ageing masculinity. But how is this popular novel read and responded to by old men themselves? This article builds on a focus group study with Swedish men aged 65-92 who read and discussed A Man Called Ove. The aim of this article is thus to explore how men read the novel and how these readings function as ways of constructing, negotiating and challenging ageing masculinity and the old man as a gendered and aged position. Findings of the study show how discussion of the novel generated a variety of "imaginary positions" through which the participants made sense of what it means to be an old man in contemporary Sweden, including positions such as the active aspiring ageing man, the passive lonely old man, the embodied and vulnerable old man, and the dutiful old man. Future research should explore how other literary genres may provide ways of understanding how old men's gendered and aged subjectivities are constructed.
