Harmonic errors of a 9.4 T all-REBCO NMR magnet affected by screening current and geometric inconsistency of coated conductors.

REBa 2 Cu 3 O 7 - x (REBCO, RE = rare earth)-coated conductor is a competitive option in terms of current-carrying capacity and high-stress durability in developing high-field magnets for nuclear magnetic resonance (NMR) research. Meanwhile, a technical challenge in utilizing a stand-alone REBCO NMR magnet is an unexpected difference in the field uniformity between the designed and measured values after being constructed and charged, i.e., harmonic errors. Bortot et al., and Li et al., reported analytic evidence of the related issue. However, sufficient research has not yet been conducted, so evidence should be supplemented further. Here we report harmonic errors due to screening current and inconsistent conductor thickness, confirmed by a 400 MHz 1H NMR magnet development project. The magnet was first charged up to its operating current, and then multiple overcharge-discharge cycles were applied, which was an empirically optimized operation protocol. A field mapping device obtained magnetic fields at designated locations in the room-temperature bore. The result showed over 100 ppm field uniformity difference between designed and measured values. A simulation model was developed considering screening current and inconsistent conductor thickness for reproducing the field distribution. Comparison of voltages and fields between simulation and measurement validated the model. Further analysis of the overcharge-discharge effect on harmonic errors demonstrated that even and odd-order harmonics are mainly attributed to screening current and geometric inconsistency while confirming the limitation of the screening current mitigation effect. Hence, we concluded that the desirable requirement of the sub-ppm level field uniformity generation might be barely possible with the current REBCO NMR magnet design approach.

Meat quality and safety issues during high temperatures and cutting-edge technologies to mitigate the scenario.

Climate change, driven by the natural process of global warming, is a worldwide issue of significant concern because of its adverse effects on livestock output. The increasing trend of environmental temperature surging has drastically affected meat production and meat product quality, hence result in economic losses for the worldwide livestock business. Due to the increasing greenhouse gas emissions, the situation would get prolonged, and heat exposure-related stress is expected to worsen. Heat exposure causes metabolic and physiological disruptions in livestock. Ruminants and monogastric animals are very sensitive to heat stress due to their rate of metabolism, development, and higher production levels. Before slaughter, intense hot weather triggers muscle glycogen breakdown, producing pale, mushy, and exudative meat with less water-holding capacity. Animals exposed to prolonged high temperatures experience a decrease in their muscle glycogen reserves, producing dry, dark, and complex meat with elevated final pH and increased water-holding capacity. Furthermore, heat stress also causes oxidative stresses, especially secondary metabolites from lipid oxidation, severely affects the functionality of proteins, oxidation of proteins, decreasing shelf life, and food safety by promoting exfoliation and bacterial growth. Addressing the heat-related issues to retain the sustainability of the meat sector is an essential task that deserves an inclusive and comprehensive approach. Considering the intensity of the heat stress effects, this review has been designed primarily to examine the consequences of hot environment temperatures and related stresses on the quality and safety of meat and secondarily focus on cutting edge technology to reduce or alleviate the situational impact.

The Application of High-Intensity Ultrasound on Wet-Dry Combined Aged Pork Loin Induces Physicochemical and Oxidative Alterations.

This research investigated the synergic outcome of high intensity ultrasound (HIU) treatment and wet-dry combined aging (WDCA) on physiochemical characteristics and lipid oxidation during refrigerated storage to ameliorate pork meat's quality and shelf life. The CIE b* values, cooking loss (CL %), and pH of the HIU treated samples were higher than those of the control over the aging period. They were significantly (p<0.05) modified by the aging period and ultrasound (US) treatment. However, the released water (RW %) and moisture were not significantly influenced by US treatment (p>0.05). The Warner-Bratzler shear force of HIU-treated samples was lower over control values except in 7-14 d, and it showed a significant difference between control and US treatment according to the significance of HIU (p<0.05). The thiobarbituric acid reactive substance of HIU-treated samples was significantly higher (p<0.05) than control values over the aging period. These results suggested that HIU treatment and WDCA showed a synergistic effect of maximizing the tenderness, but lipid oxidation was higher than before ultrasonic treatment. In agreement with this, the most favorable approach would involve implementing wet aging for a period of two weeks followed by dry aging for a period not exceeding one week after the application of HIU.

What Did the Ideal Beauty of the 15th Century Look Like? An Anthropometric Analysis of Botticelli Portraits.

The aim of this study was to conduct an anthropometric analysis of the 5 portraits painted by Botticelli that depict Simonetta Vespucci. Five images in the Simonetta series by Botticelli workshop were measured. The anthropometric measurements of the face included 22 parameters on the lateral view (in 4 portraits; 18 distances and 4 angles) and 17 distances on the frontal view (in one portrait), which were measured using Adobe Photoshop. The absolute distances were calculated relative to the vertical corneal diameter (10.6 mm), which was calculated by multiplying the distance from the pupil's center to the lower margin of the iris. In the lateral faces, the nasofrontal angle (g-n-prn) was 157.6±2.4 degrees, and the nasal tip angle (n-prn-sn) was 99.7±3.4 degrees. The nasolabial angle (prn-sn-ls) was 125.7±4.9 degrees, and the labiomental angle (li-sl-pg) was 131.6±4.4 degrees. The ratio of the upper lip height to the lower lip height (sn-sto/sto-sl) was 85.4±9.0%. The ratio of the upper lip vermillion to the upper lip height (ls-sto/sn-sto) was 27.7±3.9%. The ratio of the lower lip vermillion to the lower lip height (sto-li/sto-sl) was 47.2±6.6%. Comparing the data with 21st-century Italian females, forehead II height (tr-n), physiognomical face height (tr-gn), and morphologic face height (n-gn) of the beauties of the 15th century were significantly greater than those of 21st-century Italian females. However, there were no significant differences in lower face height (sn-gn) and nose height (n-sn). Considering the ongoing cultural relevance of Renaissance art, the esthetic proportions from this study may have reflection to the present day plastic surgery.

Defining the cellular origin of seminoma by transcriptional and epigenetic mapping to the normal human germline.

Aberrant male germline development can lead to the formation of seminoma, a testicular germ cell tumor. Seminomas are biologically similar to primordial germ cells (PGCs) and many bear an isochromosome 12p [i(12p)] with two additional copies of the short arm of chromosome 12. By mapping seminoma transcriptomes and open chromatin landscape onto a normal human male germline trajectory, we find that seminoma resembles premigratory/migratory PGCs; however, it exhibits enhanced germline and pluripotency programs and upregulation of genes involved in apoptosis, angiogenesis, and MAPK/ERK pathways. Using pluripotent stem cell-derived PGCs from Pallister-Killian syndrome patients mosaic for i(12p), we model seminoma and identify gene dosage effects that may contribute to transformation. As murine seminoma models do not exist, our analyses provide critical insights into genetic, cellular, and signaling programs driving seminoma transformation, and the in vitro platform developed herein permits evaluation of additional signals required for seminoma tumorigenesis.

Ir(triNHC)-Catalyzed Upcycling of Waste PET for Lactic Acid Production with Sustainable Isolation via Bipolar Membrane Electrodialysis.

For the upcycling of waste polyethylene terephthalate (PET), encompassing both colored and fabric PET materials, we investigated the Ir(triNHC)-catalyzed dehydrogenative coupling of PET and methanol, leading to the production of sodium lactate with good yields. We proposed a sustainable method for isolating lactic acid from the catalytic reaction mixture of sodium lactate and regenerating the base using bipolar membrane electrodialysis (BMED). This isolation method demonstrated high effectiveness, achieving isolation of lactic acid while maintaining economic feasibility at $ 0.10 per kg of lactic acid, and enabling sustainable NaOH regeneration with complete resource circulation. We assessed the recyclability of the catalyst and elucidated the mechanism involving base-mediated depolymerization and catalyst-promoted dehydrogenation, highlighting the importance of triNHC ligands in enhancing catalytic activity.

Scaffolding fundamentals and recent advances in sustainable scaffolding techniques for cultured meat development.

In cultured meat (CM) production, Scaffolding plays an important role by aiding cell adhesion, growth, differentiation, and alignment. The existence of fibrous microstructure in connective and muscle tissues has attracted considerable interest in the realm of tissue engineering and triggered the interest of researchers to implement scaffolding techniques. A wide array of research efforts is ongoing in scaffolding technologies for achieving the real meat structure on the principality of biomedical research and to replace serum free CM production. Scaffolds made of animal-derived biomaterials are found efficient in replicating the extracellular matrix (ECM), thus focus should be paid to utilize animal byproducts for this purpose. Proper identification and utilization of plant-derived scaffolding biomaterial could be helpful to add diversified options in addition to animal derived sources and reduce in cost of CM production through scaffolds. Furthermore, techniques like electrospinning, modified electrospinning and 3D bioprinting should be focused on to create 3D porous scaffolds to mimic the ECM of the muscle tissue and form real meat-like structures. This review discusses recent advances in cutting edge scaffolding techniques and edible biomaterials related to structured CM production.

Aconite-Induced Metamorphosis From Beauty to Ugliness in a Japanese Tale.

The authors present a narrative that details the cause and process of a woman's transformation from beauty to ugliness in a Japanese tale. In " Tokaido Yotsuya Kaidan ," the metamorphosis from a beauty to an ugly woman is analyzed. After taking medication to recover from childbirth, Oiwa's face became disfigured and grotesque. Oiwa: It seems to be good for my blood, but when I drink it, it causes fraying and breakdown, causing sudden pain. I feel a numbing dullness. When she looked at herself in the mirror, she was shocked. Oiwa: What's wrong with my face? I hate this, it's such a disgusting thing. Neighbor: It was a lie that the medicine you drank was a helpful medicine that protects the appearance of people's faces. Your face is that of a wicked woman (). Oiwa: Is it really me? Why does she have the face of an evil woman? Her hair falls out in a gruesome combing scene, driving her mad. The poison Oiwa took was aconite, which grows wild in Japan. Both aconite tincture and raw aconite roots contain high concentrations of Aconitum alkaloids, which can penetrate the stratum corneum following the diffusion gradient. As her hair fell out during a horrific combing session, she abandoned her maternal role and sought revenge, having lost what she considered a symbol of her femininity. In treating female patients with facial disfigurement, it is important to be mindful of their psychological state, akin to that of Oiwa, who became disfigured through no fault of her own.

Images of Modern Beauties in the Japanese Colonial Era of Korea (1910-1945).

This study aimed to analyze images of the modern beauty of Korea during the Japanese colonial era. Searches were conducted on Google ( www.google.com ) and Naver ( www.naver.com ) for archives of newspapers and magazines that contained images of beauty. Beauty of the face and neck (the early 1920s): an article (1922) detailed the contemporary beauty standards. It specifies the desired characteristics of the eyes, nose, and mouth and dictates that "the cheeks ought to be plump enough to obscure the cheekbones" and "the neck and shoulders should also be full, concealing the collarbones." Images of beauty showing balance and proportion (the late 1920s): in 1928, a magazine article introduced the concept of "the world's beauty from a scientific perspective," which represented Western esthetics as reflected in the "Canon" of body proportions and Vitruvian Man. From the face to the body (from the late 1920s to 1930s): in 1927, a daily newspaper established the standard for global beauty. During this period, there was an increased emphasis on maintaining the body, rather than just the face, as a crucial aspect of beauty. From the mid-1930s, the concept of a "streamlined" female body shape gained popularity. Male gaze, which fragmented and objectified women's bodies, had been visualized and mass-produced. It is essential to understand how preferences have evolved and to possess skilled hands capable of improving the face and body. To properly sculpt the face and body, keen eyes and adept hands are needed.

Beauty Pageants in the Japanese Colonial Era of Korea (1931 and 1940).

The aim of this study was to analyze the beauty pageants that were held in Korea during the Japanese colonial era (1931, 1940). Through searches of www.google.com and www.naver.com, 3 pageants were found: (1) 1931, Miss Korea, organized by Samchunli (a magazine): Any Korean woman, with the exception of Korean geishas, could apply by submitting her photographs. The number of candidates was 326. Nine Korean judges evaluated the photos of the candidates. Among them, the victor was an 18-year-old Korean woman. (2) 1931 (Oct), Miss Joseon, organized by Osaka Mainichi Shimbun: The candidates were categorized into 2 groups: 10 "internals" (Japanese) and 10 Koreans. Their heights and weights, along with their photographs, were provided for the readers' reference. The winners were determined based on the readers' votes. The Japanese victor was a 21-year-old student with a height of 150 cm and a weight of 52 kg (body mass index [BMI] 23.11 kg/m2). The Korean winner was a 19-year-old student standing at 157 cm and weighing 53 kg (BMI 21.50 kg/m2). (3) 1940, Venus of the Peninsula, organized by Modern Japan (a magazine): The candidates were Korean women residing in Japan or Korea. The panel of judges evaluated the photographs of the candidates. The victor was a 20-year-old Korean geisha. Her winning photograph was featured in the Korean edition of the magazine Modern Japan. She stood at 157 cm in height and weighed 45 kg (BMI 18.25 kg/m2). As beauty standards evolved over time, the beauty standards of the 1930s were markedly different from those of today.

Effect of Sample Geometry on Graphitization of Polyacrylonitrile.

In this study, it is analyzed how sample geometry (spheres, nanofibers, or films) influences the graphitization behavior of polyacrylonitrile (PAN) molecules. The chemical bonding and changes in the composition of these three geometries are studied at the oxidation, carbonization, and graphitization stages via scanning electron microscopy (SEM), in situ thermogravimetric-infrared (TGA-IR) analysis, elemental analysis, Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). The influence of molecular alignment on the graphitization of the three sample geometries is investigated using synchrotron wide-angle X-ray diffraction (WAXD) and transmission electron microscopy (TEM). The effects of molecular alignment at different draw rates during spinning are explored in detail.

Modern Concepts of Restructured Meat Production and Market Opportunities.

Restructured meat (RM) products are gaining importance as an essential component of the meat industry due to consumers' interest in health benefits. RM products imply the binding or holding of meat, meat by-products, and vegetable proteins together to form a meat product with meat's sensory and textural properties. RM products provide consumers with diversified preferences like the intake of low salt, low fat, antioxidants, and high dietary fiber in meat products. From the point of environmental sustainability, RM may aid in combining underutilized products and low-valued meat by adequately utilizing them instead of dumping them as waste material. RM processing technique might also help develop diversified and new hybrid meat products. It is crucial to have more knowledge on the quality issues, selection of binding agents, their optimum proportion, and finally, the ideal processing techniques. It is observed in this study that the most crucial feature of RM could be its healthy products with reduced fat content, which aligns with the preferences of health-conscious consumers who seek low-fat, low-salt, high-fiber options with minimal synthetic additives. This review briefly overviews RM and the factors affecting the quality and shelf life. Moreover, it discusses the recent studies on binding agents in processing RM products. Nonetheless, the recent advancements in processing and market scenarios have been summarized to better understand future research needs. The purpose of this review was to bring light to the ways of sustainable and economical food production.

Umami Characteristics and Taste Improvement Mechanism of Meat.

Taste is one of the five senses that detect vital information about what we are eating. Comprehending taste is crucial for enhancing the flavor of foodstuffs and high-protein foods like meat. Umami has global recognition as the fifth elementary taste, alongside sweetness, sourness, saltiness, and bitterness. Umami compounds are known to enhance the sensation of recognized flavors such as salty, sweet, bitter, and others. This could end up in greater food consumption by consumption by consumers. With the rising global population, meat consumption is rising and is projected to double by 2025. It is crucial to comprehend the umami mechanism of meat and meat products, identify novel compounds, and employ laboratory methodologies to gather varied information. This knowledge will aid in the development of new consumer products. Although very limited information is available on umami taste and compounds in meat through research data. This article discusses recent advancements in umami compounds in other foodstuff as well as meat to aid in designing future research and meat product development. Moreover, another objective of this review is to learn present techniques in foodstuffs to enhance umami taste and utilize that knowledge in meat products.

Creating Double Eyelids in the Japanese Colonial Era of Korea (1910-1945).

The aim of this study was to analyze the origins of the double-eyelid procedure in Korea during the Japanese colonial era. Through Google (www.google.com) and Naver (www.naver.com), the archives of newspapers and magazines were searched. The following topics were identified: ideal eyes in the Japanese colonial era, creating double eyelids using a non-surgical method, the first case of a double-eyelid operation in a Korean woman, and the presumed first case of a double-eyelid operation in Korea. By 1935, possessing double eyelids had come to be recognized as a symbol of modern beauty. An article suggested that women with small eyes consider surgery to transform their "single eyelid" into a "double-eyelid." It endorsed plastic surgery as a marker of "worldly progress." In 1939, a magazine featured an advertisement for Aihon tape, which was promoted to create "double eyelids." Oh Yeop-ju, the first Korean hairdresser, underwent double-eyelid surgery at an Ophthalmology Clinic in Japan, sometime between 1927 and 1932. She is celebrated as a beauty icon who broadened the beauty horizons of Korean women. After returning in 1933 with a "very beautiful" appearance resulting from successful double-eyelid surgery, she received a special invitation to the Kong Eye Center in Seoul, which opened in 1937. Upon hearing her detailed account and examining her eyelids, the clinic began offering double-eyelid surgery. The technique for double-eyelid surgery was introduced from Japan and disseminated through a medical journal and to patients who had undergone the procedure in Japan.

Features of Ugly but Capable Women of Ancient China.

The aim of this study was to analyze the appearance of women viewed as "ugly but capable" in ancient China. A Google search was conducted for the "Four Great Ugly Women." Information on 3 women was collected from Lienüzhuana, a collection of biographies of eminent women compiled by the Former Han period. With the addition of 1 (Huang Yueying), 7 "ugly but capable" women were analyzed. The manifestations of their ugliness in the texts were recorded. Among the 7 women, 5 exhibited physical manifestations, whereas the remaining 2 were simply described as "ugly" without specific characteristics. Among the discernible body characteristics of the 5 women deemed unattractive, the most common feature was dark skin (80%), followed by body shape (60%). Other frequently observed traits included sparse or yellow hair, an upturned or overly large nose, a convex forehead, and an unattractive neck (each at 40%), with the latter potentially exhibiting a protruding Adam's apple, a thick neck, or a neck mass. Less common features were sunken eyes, a large head, and a masculine skeleton, each occurring in 20% of cases. Based on the depiction of women considered unattractive, the authors can infer that dark skin, a fat body, a large or upturned nose, sparse hair, a protruding forehead, a thick neck, deep-set eyes, and a large head were elements associated with ugliness. Through the description of the ugly woman, authors can infer the standards of ugliness in ancient China.

Effects of Manual Lymphatic Drainage with Mobilization and Myofascial Release on Muscle Activities during Dynamic Balance in Adults with Calf Muscle Shortening.

Mobilization with movement (MWM) and myofascial release (MFR) are treatment techniques that increase ankle dorsiflexion range of motion (DFROM). Manual lymphatic drainage (MLD) facilitates waste drainage and improves soft tissue tension in peripheral tissues. To date, no studies have investigated how the combination of MLD, MWM, and MFR influences the human body. The purpose of this study is to determine how the combination of MLD, MWM, and MFR affects DFROM and balance ability. We randomly assigned 16 individuals (26 feet) to one of three groups: MWM-MFR (MR), MWM-MLD (MD), or MWM-MFR-MLD (MRD) intervention. To confirm the intervention effect of each group, DFROM was assessed using a modified lunge test, and dynamic balance was measured using a modified star excursion balance test. In the results, differences were found between the MR and MRD groups in PL and mGCM activities in the 1 section (p = 0.008, p = 0.036) and between the MD and MRD groups in mGCM activity in the 4 and 5 sections (p = 0.049, p = 0.004). We suggest that the application of MRD is the most effective intervention for increasing muscle activation of the PL and mGCM during the modified star excursion balance test.

Lifestyle of Cleft Lip/Palate Patients in Korea Before the Introduction of the Millard Technique.

The authors introduce a short story about the lifestyle of a cleft lip woman in Korea, published in 1936, about 2 decades before Dr Millard operated on his first patient in Korea. A short story entitled "Ugly Thing," written by Yao-hsieh Chu, analyzed by Eonnyeon, a girl born in a rural area with a cleft lip and palate who excelled at household tasks such as sewing. Her forehead was bulging, and her eyes were protruding. She had a low-profile nose with wide nostrils. She had a left unilateral complete primary cleft, including an alveolar cleft. There was midface retraction, accompanied by a relatively prominent chin. Her voice exhibited hypernasality. People often laugh when they see Eonnyeon eating her food, exclaiming, "She's eating like a rabbit!" However, she married a young man who deserted her on their wedding night because of her appearance. Subsequently, she moved to an urban area and found work as a housemaid. One day, she was raped by a middle-aged water delivery man, who then fled. Ten months later, she gave birth to a girl who also had a cleft lip. In a moment of despair, Eonnyeon attempted to smother her baby with a pillow but stopped herself. She resolved to raise her daughter despite the challenges ahead. The mockery directed at her could be viewed as an expression of the latent sadism inherent in human nature. It is remarkable to consider the progress made since Millard performed his first cleft lip surgery in Korea in 1954.

Selective Enhancement of Viewing Angle Characteristics and Light Extraction Efficiency of Blue Thermally Activated Delayed Fluorescence Organic Light-Emitting Diodes through an Easily Tailorable Si3N4 Nanofiber Structure.

We selectively improved the viewing angle characteristics and light extraction efficiency of blue thermally activated delayed fluorescence (TADF) organic light-emitting diodes (OLEDs) by tailoring a nanofiber-shaped Si3N4 layer, which was used as an internal scattering layer. The diameter of the polymer nanofibers changed according to the mass ratio of polyacrylonitrile (PAN) and poly(methyl methacrylate) (PMMA) in the polymer solution for electrospinning. The Si3N4 nanofiber (SNF) structure was fabricated by etching an Si3N4 film using the PAN/PMMA nanofiber as a mask, making it easier to adjust parameters, such as the diameter, open ratio, and height, even though the SNF structure was randomly shaped. The SNF structures exhibited lower transmittance and higher haze with increasing diameter, showing little correlation with their height. However, all the structures demonstrated a total transmittance of over 80%. Finally, by applying the SNF structures to the blue TADF OLEDs, the external quantum efficiency was increased by 15.6%. In addition, the current and power efficiencies were enhanced by 23.0% and 25.6%, respectively. The internal light-extracting SNF structure also exhibited a synergistic effect with the external light-extracting structure. Furthermore, when the viewing angle changed from 0° to 60°, the peak wavelength and CIE coordinate shift decreased from 20 to 6 nm and from 0.0561 to 0.0243, respectively. These trends were explained by the application of Snell's law to the light path and were ultimately validated through finite-difference time-domain simulations.

The Psychology of Patients With Oral-Facial Clefts: A Review of Victor Hugo's The Man Who Laughs (L'homme qui rit).

In Victor Hugo's The Man Who Laughs, the protagonist has a facial cleft. The authors aimed to comprehend the psychological experience of a patient with a facial cleft by analyzing this novel. The novel concerns the life of a young nobleman, Gwynplaine, disfigured as a child, who travels with his protector and companion, the vagabond philosopher Ursus, and Dea, a baby girl he rescued. During the oppressive rule of the king, one of his adversaries was Lord Linnaeus Clancharlie, who had taken refuge in Switzerland. The tyrannical monarch ordered the execution of Gwynplaine's father and commissioned a surgeon, Dr Hardquannone, to carve the boy's face into a perpetual grin. The king declared that he should "laugh forever at his fool of a father." Subsequently, the king sold the boy to a group who specialized in the mutilation and disfigurement of children. On the psychology of a boy with an appearance giving the impression of laughing, Hugo wrote: "By laughing Gwynplaine made people laugh. However, he wasn't laughing. His face laughed, his thoughts did not." When Ursus met Gwynplaine, Ursus asked the boy: "What are you laughing at?" The boy replied: I'm not laughing. Ursus: Then you are terrible. Gwynplaine's unnatural laughter, which stems from an artificial deformation of the muscles, is a silent form of laughter. It represents the eternal laughter of those who do not truly laugh, signifying emotional emptiness and an accompanying sense of indifference. Plastic surgeons can restore an "unnatural laughing face" to a "natural smiling face."
