Assessment of cognitive games to improve the quality of life of Parkinson's and Alzheimer's patients.

Objectives: The core objectives of this study centre on enhancing the quality of life and well-being of individuals diagnosed with Parkinson's and Alzheimer's diseases. Our aim is to facilitate the monitoring of patient information, benefiting both caregivers and healthcare professionals. Methods: As part of the PROCare4Life platform sensorial ecosystem, a web application with six engaging cognitive games focusing on developing cognitive training and stimulating brain activity are developed. A set of metrics calculated by the application feed machine learning predictive models to evaluate the cognitive status and evolution over time. Long-term analysis of the daily cognitive ability information is used to generate high-level outcomes and identify deviations for each patient from the multimodal fusion engine. And based on these results, a recommender system provides a set of personalized notifications. Results: A 3-month pilot study that took place in five different countries shows the results obtained from 93 patients. An average of 22.4 games were completed per day and the recommender system generated a total of 260 game notifications, 37.7% of them were marked as read by the patients. The Cognitive State Score and the Deviations in Cognitive Abilities measurement, calculated by the multimodal fusion engine, when used in conjunction present a good overview of the patient's current state and potential deviations. Conclusion: The cognitive games application was well-received by elderly individuals who took part in the study. This tool can be valuable for caregivers and healthcare providers in assessing the cognitive function of patients through engaging in cognitive games.

Haptic Glove TV Device for People with Visual Impairment.

Immersive video is changing the way we enjoy TV. It is no longer just about receiving sequential images with audio, but also playing with other human senses through smells, vibrations of movement, 3D audio, feeling water, wind, heat, and other emotions that can be experienced through all human senses. This work aims to validate the usefulness of an immersive and interactive solution for people with severe visual impairment by developing a haptic glove that allows receiving signals and generating vibrations in hand, informing about what happens in a scene. The study case presented here shows how the haptic device can take the information about the ball's location in the playing field, synchronized with the video reception, and deliver it to the user in the form of vibrations during the re-transmission of a soccer match. In this way, we take visually impaired people to live a new sensory experience, allowing digital and social inclusion and accessibility to audiovisual technologies that they could not enjoy before. This work shows the methodology used for the design, implementation, and results evaluation. Usability tests were carried out with fifteen visually impaired people who used the haptic device to attend a soccer match synchronized with the glove's vibrations.

Three-D Wide Faces (3DWF): Facial Landmark Detection and 3D Reconstruction over a New RGB⁻D Multi-Camera Dataset.

Latest advances of deep learning paradigm and 3D imaging systems have raised the necessity for more complete datasets that allow exploitation of facial features such as pose, gender or age. In our work, we propose a new facial dataset collected with an innovative RGB⁻D multi-camera setup whose optimization is presented and validated. 3DWF includes 3D raw and registered data collection for 92 persons from low-cost RGB⁻D sensing devices to commercial scanners with great accuracy. 3DWF provides a complete dataset with relevant and accurate visual information for different tasks related to facial properties such as face tracking or 3D face reconstruction by means of annotated density normalized 2K clouds and RGB⁻D streams. In addition, we validate the reliability of our proposal by an original data augmentation method from a massive set of face meshes for facial landmark detection in 2D domain, and by head pose classification through common Machine Learning techniques directed towards proving alignment of collected data.

On the influence of low-level visual features in film classification.

BACKGROUND: In this paper we present a model of parameters to aesthetically characterize films using a multi-disciplinary approach: by combining film theory, visual low-level video descriptors (modeled in order to supply aesthetic information) and classification techniques using machine and deep learning. METHODS: Four different tests have been developed, each for a different application, proving the model's usefulness. These applications are: aesthetic style clustering, prediction of production year, genre detection and influence on film popularity. RESULTS: The results are compared against high-level information to determine the accuracy of the model to classify films without knowing such information previously. The main difference with other film characterization approaches is that we are able to isolate the influence of high-level descriptors to really understand the relevance of low-level features and, accordingly propose a useful set of low-level visual descriptors for that purpose. This model has been tested with a representative number of films to prove that it can be used for different applications.

[On the 50th anniversary of Anales de Pediatría, official publication of the Spanish Association of Paediatrics]. / En los 50 años de Anales de Pediatría, publicación oficial de la Asociación Española de Pediatría.

The 50th Anniversary of Anales de Pediatría is a good time for the celebration of events and tributes, and also for critical thought. Anales de Pediatría is the official publication of scientific expression of the Spanish Association of Paediatrics (AEP). It has been published continuously since October 1968. Anales has contributed so much to the narrative of the advances in Spanish paediatrics, as well as the AEP. Throughout its 50 years of history, the editorial teams of the journal have worked to streamline its management, improve the quality of the content, and to ensure its dissemination and national-international visibility. From 1968 to 1972, Anales was published as a Journal-bulletin. From 1977 until 2000, presence of original articles. Since the year 2000, continuous modernisation and recognition with international journals of prestige, indexing in SCI-JCR, impact from 2009, electronic management of manuscripts, Spanish/English from the 2014 Edition. The evolution of the journal is reviewed in this article. With this, the AEP history committee wants to collaborate in a greater understanding of the development of Spanish paediatrics, as well as to present the history of Anales to its authors and readers. The History committee proposes that a small percentage of space is destined for the humanities and to the humanisation of paediatrics. Best information will ensure the best care for children and also for paediatricians.

Correction: Improving vehicle tracking rate and speed estimation in dusty and snowy weather conditions with a vibrating camera.

[This corrects the article DOI: 10.1371/journal.pone.0189145.].

Robust vehicle detection in different weather conditions: Using MIPM.

Intelligent Transportation Systems (ITS) allow us to have high quality traffic information to reduce the risk of potentially critical situations. Conventional image-based traffic detection methods have difficulties acquiring good images due to perspective and background noise, poor lighting and weather conditions. In this paper, we propose a new method to accurately segment and track vehicles. After removing perspective using Modified Inverse Perspective Mapping (MIPM), Hough transform is applied to extract road lines and lanes. Then, Gaussian Mixture Models (GMM) are used to segment moving objects and to tackle car shadow effects, we apply a chromacity-based strategy. Finally, performance is evaluated through three different video benchmarks: own recorded videos in Madrid and Tehran (with different weather conditions at urban and interurban areas); and two well-known public datasets (KITTI and DETRAC). Our results indicate that the proposed algorithms are robust, and more accurate compared to others, especially when facing occlusions, lighting variations and weather conditions.

Improving vehicle tracking rate and speed estimation in dusty and snowy weather conditions with a vibrating camera.

Traffic surveillance systems are interesting to many researchers to improve the traffic control and reduce the risk caused by accidents. In this area, many published works are only concerned about vehicle detection in normal conditions. The camera may vibrate due to wind or bridge movement. Detection and tracking of vehicles is a very difficult task when we have bad weather conditions in winter (snowy, rainy, windy, etc.), dusty weather in arid and semi-arid regions, at night, etc. Also, it is very important to consider speed of vehicles in the complicated weather condition. In this paper, we improved our method to track and count vehicles in dusty weather with vibrating camera. For this purpose, we used a background subtraction based strategy mixed with an extra processing to segment vehicles. In this paper, the extra processing included the analysis of the headlight size, location, and area. In our work, tracking was done between consecutive frames via a generalized particle filter to detect the vehicle and pair the headlights using the connected component analysis. So, vehicle counting was performed based on the pairing result, with Centroid of each blob we calculated distance between two frames by simple formula and hence dividing it by the time between two frames obtained from the video. Our proposed method was tested on several video surveillance records in different conditions such as dusty or foggy weather, vibrating camera, and in roads with medium-level traffic volumes. The results showed that the new proposed method performed better than our previously published method and other methods, including the Kalman filter or Gaussian model, in different traffic conditions.

A novel crystalline SiCO compound.

Ab initio evolutionary structural searches have been performed on SixCyO2(x+y) compounds. A novel structure, with SiC2O6 stoichiometry and the P21/c space group is calculated to be stable against decomposition within a wide pressure window from 7.2 to 41 GPa, and metastable under ambient conditions. It consists of CO3 units, linked to SiO6 octahedra, supporting previous experimental studies. The evolution of the carbon environment towards tetrahedral CO4 units, thus resembling the crystal chemistry of silicon, is predicted at higher pressures.

From ELF to compressibility in solids.

Understanding the electronic nature of materials' compressibility has always been a major issue behind tabulation and rationalization of bulk moduli. This is especially because this understanding is one of the main approaches to the design and proposal of new materials with a desired (e.g., ultralow) compressibility. It is well recognized that the softest part of the solid will be the one responsible for its compression at the first place. In chemical terms, this means that the valence will suffer the main consequences of pressurization.It is desirable to understand this response to pressure in terms of the valence properties(charge, volume, etc.). One of the possible approaches is to consider models of electronic separability, such as the bond charge model (BCM), which provides insight into the cohesion of covalent crystals in analogy with the classical ionic model. However, this model relies on empirical parametrization of bond and lone pair properties. In this contribution, we have coupled electron localization function (ELF) ab initio data with the bond charge model developed by Parr in order to analyze solid state compressibility from first principles and moreover, to derive general trends and shed light upon superhard behavior.

Magic cards: a new augmented-reality approach.

Augmented reality (AR) commonly uses markers for detection and tracking. Such multimedia applications associate each marker with a virtual 3D model stored in the memory of the camera-equipped device running the application. Application users are limited in their interactions, which require knowing how to design and program 3D objects. This generally prevents them from developing their own entertainment AR applications. The Magic Cards application solves this problem by offering an easy way to create and manage an unlimited number of virtual objects that are encoded on special markers.

Stereoscopic system for inexpensive hazardous area three-dimensional robot localization applications based on incoherent optical fiber bundle calibrated for high-resolution image transmission.

Computer vision, despite all the recent progress, still cannot be employed technically in most hazardous and harsh industrial areas. Most of the alternative solutions to this modern issue are usually unavailable mainly due to the global visual inspection solution cost. The best suitable option is the use of an incoherent optical fiber bundle (IOFB) that obviously requires a calibration step before image transmission purpose. We already presented our contribution to this topic improving the calibration method of the IOFB for image transmission, with some additional and essential steps that considerably improve the reconstructed image quality while also drastically reducing the processing time needed. We also proposed and evaluated a new full-resolution calibration method in a very recent study. We present and discuss in this paper an application using the IOFB for robot guiding in hazardous areas, based on a stereoscopic vision system. Conclusions compare the low- and full-resolution IOFB calibration methods for the depicted application and introduce some advantages of a specially designed IOFB that could perfectly fit with some industrial applications.

Síndrome auriculotemporal de Frey. Un caso de presentación bilateral en un lactante / Frey auriculotemporal syndrome. A bilateral case in a child

El síndrome auriculotemporal o síndrome de Frey se caracteriza por la aparición de enrojecimiento, hiperhidrosis, o ambos, en la zona inervada por elnervio auriculotemporal como respuesta a un estímulo gustativo desencadenado por la ingesta de distintos alimentos. Por este motivo puede confundirseen ocasiones con alergias alimentarias. Se debe generalmente a una lesión del nervio auriculotemporal, si bien en ocasiones no existe ningún antecedentetraumático. Su aparición en la infancia y su presentación bilateral, como el caso que presentamos a continuación, son muy poco frecuentes

Frey syndrome or auriculotemporal nerve syndrome manifests as flushing, sweating, or both, localized to the distribution of the auriculotemporal nerve,in response to gustatory stimuli. Ocasionally it may be misinterpreted as foog allergy. It usually occurs as a result of injury to auriculotemporal nerve, butthere are cases with no known previous trauma. It is rarely described in children as well as the bilateral involvement, as the case we presented

Distribution of the internal pudendal artery in male and female llama (Lama glama).

The aim of this research has been to describe the internal pudendal artery distribution in male and female llama and to compare it with that of other domestic animals including the one-humped camel (Camelus dromedarius). The arterial system was perfused with a solution of 14% coloured plaster and preserved in a solution of a 10% formalin, 3% carbolic acid and 3% glycerine. The systematic dissection was made using traditional working techniques and standard instruments. The internal pudendal artery is the ventral terminal branch of the internal iliac artery at the level of the third sacral vertebra. The main supply of the pelvic organs comes from the prostatic or vaginal arteries; notwithstanding these arteries arise from the internal pudendal artery, showing an important difference between ruminants and pig (long iliac type). Similarities between the distribution of the internal pudendal artery of the llama and those obtained in the camel provide strong evidence of a common phylogenetic origin.

Prevalencia de la infección por el virus del papiloma humano en mujeres con citologías anormales del cérvix uterino y factores de riesgo asociados a la infección / Prevalence of human papillomavirus infection in women with abnormal pap-smears of the uterine cervix and risk factors associated to the infection

Objetivo: Conocer la prevalencia de la infección por el virus del papiloma humano (VPH) en mujeres con citologías anormales del cérvix uterino y determinar los factores de riesgo asociados a la infección. Sujetos y métodos: Ochenta y una mujeres, que presentaron una citología con el diagnóstico de atipia de significado incierto (ASCUS), lesión escamosa intraepitelial de bajo grado (L-SIL) o de alto grado (H-SIL), se sometieron a un cuestionario epidemiológico, detección del VPH mediante la prueba Hybrid Capture II®, estudio histológico y análisis de otras enfermedades de transmisión sexual. Resultados: Se estudiaron 16 mujeres con citologías con resultado de ASCUS, 44 con L-SIL y 21 con H-SIL. La prevalencia global de la infección por el VPH fue del 67,9% (55 casos). Se detectó el VPH de alto riesgo (VPH-AR) en 50 (61,8%). Los porcentajes de infección por el VPH-AR en las mujeres con citologías con ASCUS, L-SIL y H-SIL fueron del 31,2, 63,6 y 80,9%, respectivamente. La infección por el VPH se asoció de forma significativa con el número de parejas sexuales a lo largo de la vida (χ2 de tendencia: 4,187; p = 0,0407). Conclusiones: Las mujeres con citologías con resultado de ASCUS son las que más pueden beneficiarse de las técnicas que detectan el VPH-AR, debido a la menor prevalencia de la infección. El principal factor de riesgo asociado a la infección por el VPH fue el número de parejas sexuales a lo largo de la vida

Objectives: To determine the prevalence of human papillomavirus (HPV) infection in women with an abnormal pap smear of the uterine cervix and to determine the risk factors associated with HPV infection. Subjects and methods: Eighty-one women with a cytological result of atypical cells of unknown origin (ASCUS), low-grade squamous intraepithelial lesions (LG-SIL) or high-grade squamous intraepithelial lesions (HG-SIL) were referred for epidemiological questionnaire, HPV detection performed using the Hybrid Capture II® test, histological study, and analysis of other sexually-transmitted diseases. Results: Cytologic study identified 16 women with ASCUS, 44 with LG-SIL and 21 with HG-SIL. The global prevalence of HPV infection was 67.9% (55 patients) and high-risk HPV (HR-HPV) infection was detected in 50 patients (61.8%). The percentages of HR-HPV infection in women with ASCUS, L-SIL and H-SIL were 31.2%, 63.6% and 80.9%, respectively. The number of sexual partners over a woman's lifetime was significantly associated with HPV infection (χ2 for trend: 4.187; p = 0.0407). Conclusions: Women with ASCUS detected by cytology are those who could most benefit from HR-HPV detection techniques, because of the lower prevalence of the infection. The main risk factor associated with HPV infection was the number of sexual partners over a woman's lifetime
