Misdiagnosis of psoriatic arthritis in a patient with paronychia confirmed by dermatological examination: A case report
Authors: Nigro Angelo
Published: February 2025

BACKGROUND

This case highlights the importance of a multidisciplinary approach in differentiating localized infections from systemic inflammatory diseases like psoriatic arthritis. Nail psoriasis can mimic conditions like paronychia, complicating diagnosis. We wrote this report to emphasize the need for clinical vigilance when interpreting imaging findings, especially in patients with a family history of psoriasis. Misdiagnosis can lead to unnecessary systemic treatments, underscoring the significance of dermatological input in achieving accurate diagnoses.

CASE SUMMARY

A 56-year-old woman presented with redness and swelling of multiple fingertips. Her family history of psoriasis raised suspicion of psoriatic arthritis. Two rheumatologists diagnosed psoriatic arthritis based on ultrasound findings of enthesitis with a positive Doppler signal and recommended methotrexate. However, she was reluctant to initiate therapy due to potential side effects. At our Rheumatology Center, paronychia was suspected, and laboratory tests excluded systemic inflammatory arthritis. Dermatological examination confirmed paronychia, and treatment with fluconazole and ceftriaxone was initiated to address suspected mixed bacterial and fungal infections. Imaging studies, including hand and wrist X-rays, showed no erosions or other signs of psoriatic arthritis. The patient responded well to antimicrobial therapy, with resolution of symptoms. This case highlights the need for thorough clinical evaluation, careful interpretation of imaging findings, and collaboration between rheumatologists and dermatologists to avoid misdiagnosis and inappropriate treatment.

CONCLUSION

This case underscores the need for thorough clinical evaluation and caution in interpreting nonspecific imaging findings, especially in patients with a family history of psoriasis. While familial predisposition may raise suspicion for psoriatic arthritis, it is essential to integrate laboratory data, imaging studies, and clinical presentation, including response to targeted antimicrobial therapy. A multidisciplinary approach, involving both rheumatologists and dermatologists, is crucial to preventing misdiagnosis, ensuring appropriate treatment, and avoiding the potential harms of unwarranted therapies.

Authors: Iwamuro Masaya , Yoshikawa Tomoki , Kamio Tomohiro , Hirata Shoichiro , Matsueda Katsunori , Kametaka Daisuke , Otsuka Motoyuki
Published: February 2025

BACKGROUND

Gastric bezoars are masses of indigestible material that accumulate in the stomach, causing nausea, abdominal pain, and vomiting. Persimmon bezoars (diospyrobezoars), which comprise tannins and fibers from persimmons, are relatively rare but may cause significant gastric complications, including gastric outlet obstruction or ileus. Although computed tomography (CT) is a useful imaging tool, diagnosing bezoars can be challenging because their density is similar to that of food debris and gastric content.

CASE SUMMARY

Here, we report the case of a 72-year-old woman with a persimmon bezoar that was diagnosed using serial CT imaging and confirmed by endoscopy. CT performed over several months revealed changes in the internal structure and density of the bezoar, suggesting progressive hardening. The patient had a history of a partial gastrectomy and excessive persimmon consumption, both of which are risk factors for bezoar formation. Endoscopic fragmentation of the bezoar successfully resolved symptoms.

CONCLUSION

Gastric bezoars, particularly persimmon bezoars, present diagnostic challenges because of their variable imaging characteristics. Serial CT can document temporal changes in bezoar density, potentially reflecting changes in hardness. Early diagnosis and endoscopic treatment are essential for effective management, particularly in patients with predisposing factors. This case underscores the importance of considering bezoars in the differential diagnosis of gastric masses, and highlights the value of CT for monitoring changes in bezoar characteristics over time.

Authors: Martínez-Hincapie Cristina Isabel , González-Arroyave Daniel , Ardila Carlos M
Published: February 2025

BACKGROUND

Rectal foreign bodies, though uncommon, present diagnostic and therapeutic challenges, particularly when they result from accidental ingestion. The nonspecific symptoms and the potential for serious complications necessitate a thorough and methodical approach to diagnosis and treatment. This case report aims to highlight the diagnostic complexities and management strategies involved in treating a patient with a rectal foreign body, focusing on the use of advanced imaging techniques and the importance of a multidisciplinary approach.

CASE SUMMARY

A 48-year-old male with a history of hypertension presented with a one-year history of post-defecation anorectal pain and mild post-defecation rectorrhagia. Initial evaluation revealed hemodynamic stability and a tender, non-mucosal lesion in the anterior left rectal region. Imaging studies, including colonoscopy, magnetic resonance imaging, and endosonography, identified an erythematous, exophytic lesion and a perirectal abscess containing a foreign body. Surgical intervention revealed necrotic tissue and purulent material, along with two solid foreign body fragments (bone or plant matter). Postoperative follow-up showed the patient in good condition, and pathology confirmed the fragments as mature bone.

CONCLUSION

This case underscores the diagnostic challenges posed by rectal foreign bodies with nonspecific symptoms and no clear history of ingestion.

Published: February 2025

BACKGROUND

Breast cancer is a leading cause of cancer-related mortality among women worldwide, with invasive ductal carcinoma (IDC) being the most prevalent subtype. Lymph node metastasis is the primary prognostic indicator, typically evaluated via biopsy of the ipsilateral sentinel or axillary lymph nodes. Contralateral axillary metastasis (CAM) without ipsilateral involvement is exceedingly rare, particularly in early-stage breast cancer. This report presents a case of CAM in a patient with triple-negative breast cancer (TNBC), underscoring diagnostic and therapeutic complexities.

CASE SUMMARY

A 73-year-old female presented with left-sided early-stage IDC in February 2023. Despite a modified radical mastectomy and pathologically negative ipsilateral lymph nodes, a postoperative positron emission tomography (PET) scan detected fluorodeoxyglucose-avid nodes in the contralateral axilla. Biopsy confirmed metastatic ductal carcinoma with triple-negative status, resulting in an upstaged diagnosis of metastatic breast cancer, stage IV, M1. The patient underwent six cycles of adjuvant chemotherapy, with follow-up PET imaging showing regression of the contralateral lesion. This case highlights the importance of advanced imaging in TNBC for precise staging and treatment optimization.

CONCLUSION

This case highlights the aggressive nature of TNBC and the need for advanced imaging to ensure accurate staging and effective management.
New surgical approach for distal clavicle fractures: A case report
Authors: Hu Wen-Tao , Zhang Zi-Yan , Qu Ji , Piao Cheng-Dong
Published: February 2025

BACKGROUND

Clavicle fractures are a common type of fracture that often occurs after high-energy trauma. The treatment methods for clavicle fractures remain controversial. Both locking compression and hook plates are recommended.

CASE SUMMARY

A 44-year-old male suffered an injury during skiing. Radiography revealed a right-sided distal clavicular fracture. The fracture was treated using a hook plate due to its small size. During the surgical procedure, Kirschner wires were used to drill holes in the acromion. The end of the hook plate was inserted into the hole rather than below the edge of the acromion.

CONCLUSION

One year later, imaging revealed complete healing of the fracture, and the hook plate was removed. The patient was satisfied with the course and treatment results. Additionally, a new classification system was proposed based on the degree of injury to the distal clavicle joint surface. The incidence of postoperative complications associated with the use of hook plates for clavicular fracture treatment is relatively high. Complications can be reduced by changing the hook plate placement.
Rates of p16 and p53 expression in head and neck cutaneous squamous cell carcinoma vary according to human papillomavirus status
Authors: Ait Addi Rachid
Published: February 2025

The strong association between human papillomavirus (HPV) infection and oropharyngeal squamous cell carcinoma (SCC) is well-documented, with p16 expression serving as a reliable predictor of HPV involvement. HPV-related tumors are characterized by distinct mechanisms affecting p16 and p53 protein pathways. However, the prevalence of HPV and the combined predictive utility of p16 and p53 expression in head and neck cutaneous SCC remain less explored, necessitating further research to understand their role in this subset of SCC. HPV, p16, and p53 statuses were determined using immunohistochemistry staining methods rather than more sensitive techniques such as polymerase chain reaction or HPV genotyping, limiting the ability to assess specific area HPV types potentially associated with prognosis. Further studies assessing multiple molecular markers in head and neck cutaneous patients will better predict the diverse outcomes and potentially the type of treatment targeted to those markers.

Authors: Yeshuai Chen , Guoliang Bian , Jianguo Gong
Published: February 2025

In the northern regions of China, the co-location of new energy sources and thermal power plants at a single grid connection point has led to the formation of a unique operational entity. This configuration adheres to an operational paradigm where new energy predominantly fulfills contracted electricity requirements, while thermal power facilities provide ancillary services. This arrangement facilitates a synergistic integration of thermal and renewable energy resources, showcasing substantial potential in the peak regulation auxiliary service market. To rigorously assess the financial performance of such a coupled system in the peak regulation market, this study initially delineates the structure of a wind-solar-thermal coupled system at a unified grid connection point and subsequently evaluates its economic impact within the auxiliary service market. The analysis progresses by employing a bubble sorting methodology to model the participation of this integrated system in the market. Furthermore, the research implements a practical case study by establishing a coupled system in a specified locale within Liaoning Province, wherein its market performance and economic benefits are critically examined. Comparative analysis indicates that the coupled system significantly outperforms traditional power sources and its standalone counterparts in terms of market efficiency and economic viability in the peak regulation context. In the scenario set up in this paper, the revenue capacity of the peaking auxiliary service market after system coupled is enhanced compared with that before coupled, the revenue increases by 2 million yuan.
Research on Power Balance and Measurement of New Energy Power System Based on Graph Neural Network
Authors: Liyan Kang , He Cui , Leiyang Zhao
Published: February 2025

With the surge of new technologies, such as high penetration of new energy, ultra-high voltage transmission, and intelligent digital power grids, the power system has become increasingly complex and requires stricter safety and stability standards. To address this issue, this paper introduces a transient stability analysis method using graph convolutional neural networks. This method combines short-term simulation with neural network prediction, reducing analysis time and making it suitable for various simulation scenarios. It also combines models with algorithms to quickly and robustly optimize transient stability control strategies for expected faults. This method is superior to traditional methods in terms of runtime and efficiency. The test results of IEEE-30 and IEEE-39 node systems confirm the effectiveness, efficiency, and superiority of our proposed method. In high-tech energy systems, the volatility and uncertainty of wind and photovoltaic power generation output significantly affect power balance. The increasing renewable energy production capacity in China poses a challenge to reliable electricity supply. Based on actual data analysis of daily and seasonal fluctuations in new energy output, we have summarized power balance issues at different time scales. Using a time series production simulation model, the balance problem in high-tech energy systems was studied, and the supply shortage of typical power grids was quantitatively analyzed. Solutions were proposed, with the daily peak fluctuation of new energy in the power grid reaching 79.96 million kilowatts, an increase of 41% compared to the previous year.

Published: February 2025

In response to the high voltage stress issue in the secondary components of the DC/DC converter caused by increasing the electric vehicle charging system from 400V to 800V, a low-voltage seamless charging switching technique is proposed, a low-voltage seamless charging switching technique is proposed. Building upon the optimized design of the 400V DC to DC Converter, this technique utilizes the Battery Selection Circuit (BSC) to enable charging of 800V high-voltage batteries. The topology is described, along with a simple modulation scheme, providing a detailed explanation of how the BSC circuit achieves seamless and dead-time-free charging for two 400V batteries. This enhances the reliability of the converter, reducing grid load fluctuations caused by the charging of a considerable number of electric vehicles. The lower voltage stress on the converter components and the separate design of the BSC circuit’s switching frequency result in overall lower losses and improved efficiency and energy utilization on demand side of the system. Finally, an experimental prototype is built to further validate the feasibility of the proposed technique.

Published: February 2025

Distributed renewable energy sources such as wind, solar, and small hydropower of the new distribution network are mainly connected to the grid through distribution lines, which are susceptible to lightning overvoltage. Therefore, this paper conducts a lightning risk assessment of the active distribution network system, including the photovoltaic (PV) side and the line-side. The study analyzes the effectiveness of two lightning protection measures: strengthening insulation and installing lightning arresters in the new distribution network. Strengthening insulation involves enhancing the first three towers and all line towers. However, the results show that both methods cannot effectively reduce the lightning failure rate on the PV-side and may even lead to adverse effects. Additionally, the analysis of in stalling lightning arresters reveals that installing them on the first-level towers of the distribution line can significantly reduce the impact of lightning on both the line and PV-sides. In particular, installing lightning arresters simultaneously on the first three towers closest to the PV-side can drastically reduce the overall lightning trip rate on the line-side.

hombre-dios Quetzalcóatl: símbolo del método de la razón poética
Authors: Contreras Coll Núria
Published: February 2025

Durante los años sesenta, María Zambrano entra en contacto con la arqueóloga Laurette Séjourné, con lo que se produce en Zambrano un regreso conceptual a México que se traduce en una profunda reflexión acerca de Quetzalcóatl, el dios de la cultura náhuatl, al cual Zambrano incorporará a su pensamiento como símbolo de la aurora. En el presente estudio, se analizará cómo el mito del dios mexicano le sirve a esta filósofa para ejemplificar una operación trascendental que convertirá en método de su razón poética y que será el centro de toda acción metafórica esencial que el sujeto ha de llevar a cabo en su propia trascendencia.
concepto de España en la filosofía de María Zambrano
Authors: Navarra Ordoño Andreu
Published: February 2025

El presente artículo propone examinar qué concepto elaboró María Zambrano sobre la nación española en diversos ensayos suyos a partir de las aportaciones de Miguel de Unamuno y de Benito Pérez Galdós. Su concepción del pensamiento esencialmente español como poético, literario o místico difiere mucho de la de otros filósofos contemporáneos, como José Ortega y Gasset o Eduard Nicol; en cambio, coincide casi plenamente con las concepciones de su amigo y corresponsal Josep Ferrater Mora.

Estudiantes de Secundaria e Inteligencia Artificial: Perspectiva desde la neuroeducación sobre la Alfabetización y Superación, Pensamiento y Creatividad
Authors: Reza Flores Ricardo Alberto , Reza Flores Citlali Michélle , Zamudio Palomar Alejandra
Published: February 2025

La incorporación de la Inteligencia Artificial (IA) en la neuroeducación, representa un enorme desafío para el desarrollo de competencias digitales y personalizar el aprendizaje desde diferentes aristas. A pesar de la relativa reciente masificación global de la IA en el sistema educativo, prevalece incertidumbre por la poca disposición de datos validados, sobre cómo el estudiantado la integra en su cotidianidad académica, lo cual puede limitar el realizar ajustes pedagógicos pertinentes; además no existe la suficiente evidencia comparativa del manejo de dicha tecnología entre el sector público y privado. A tal efecto, la investigación tuvo como objetivo: analizar del estudiantado de educación secundaria, cómo se alfabetiza en el uso de la IA y desarrolla con esta tecnología sus capacidades cognitivas y creativas, para consolidar metas personales y académicas. La metodología adoptó un enfoque cuantitativo, transversal y descriptivo, sustentado en un instrumento ad hoc aplicado a 576 estudiantes de secundaria de escuelas públicas y privadas; se hicieron pruebas de confiabilidad mediante el Alfa de Cronbach y estadísticos no paramétricos a través de la Chi Cuadrado de Pearson y U de Mann-Whitney. Los hallazgos revelan de los estudiantes sobre la IA que: reconocen su importancia y muestran interés por utilizarla; no todos han sido alfabetizados para su manejo en sus escuelas, algunos la han aprendido a usar por motivación intrínseca; consideran que puede ayudarles a consolidar logros; piensan que puede potenciar su creatividad, sin que disminuya su capacidad cognitiva; y expresaron que el uso desmedido de esta tecnología puede ocasionar una fuerte dependencia que derive en procrastinación. Se concluye que alfabetizar al estudiantado con IA puede ser crucial para incorporarlos como ciudadanos digitales en un mundo hiperconectado; neuroeducativamente, la IA se convierte en un elemento sustantivo para optimizar los procesos educativos, al promover adaptación cognitiva y creativa al personalizar el aprendizaje, y más al demostrar que existe motivación de los estudiantes por su uso; se debe fomentar el desarrollo de las competencias digitales en un marco ético y responsable; y el profesorado debe de incorporar asertivamente esta tecnología en el aula para promover aprendizajes significativos y duraderos.
Los desafíos ético-legales de la experimentación de quimeras
Authors: Aravena Flores Marcos Antonio
Published: February 2025

La experimentación genética con células animales y humanas ha dado lugar a la creación de las denominadas quimeras o animales quiméricos en etapas tempranas de gestación embrionaria, generando desafíos éticos y jurídicos. Desde la perspectiva ética, se enfrenta la visión antropocéntrica con la biocéntrica, mientras que en el ámbito legal se observa una regulación insuficiente que permite o tolera estas prácticas. Frente a ello, este trabajo contribuye a la discusión de estos desafíos y sostiene que la investigación debe desarrollarse con precaución y responsabilidad científica, respetando los límites de la dignidad humana y animal. Aunque la creación de quimeras humano-animales se encuentra en una etapa inicial, el progreso tecnológico sitúa estos experimentos en un punto crítico que limita las fronteras de lo éticamente aceptable, demandando una reflexión profunda sobre las implicancias de estas prácticas en la protección de la dignidad de todas las especies involucradas.
Aborto terapéutico en casos de violación en Perú: barreras de cuidado bajo el enfoque de derechos del paciente
Authors: Angulo-Bazán Yolanda , Albuquerque Aline
Published: February 2025

Perú es uno de los países en los que el embarazo no deseado en niñas y adolescentes producto de violación sexual es más frecuente. En marzo del año 2023, la Corte Suprema de Justicia confirmó la constitucionalidad de la Guía Técnica del Ministerio de Salud de Perú para interrupción voluntaria por indicación terapéutica del embarazo menor de 22 semanas, aplicable a cualquier niña o adolescente víctima de violación sexual con un embarazo no deseado, previa aprobación de una junta médica. Sin embargo, la realidad ha demostrado ser distinta y la falta de acceso al aborto legal sigue siendo un problema para las niñas y adolescentes que necesitan de ello. En este contexto, el Enfoque de Derechos Humanos del Paciente (EDHP) puede ofrecer un marco teórico para el debate bioético y la solución de problemas clínicos bajo la inclusión de derechos humanos y principios como la toma de decisiones compartidas y la dignidad humana, buscando un cuidado centrado en la persona. El objetivo de este artículo es identificar barreras al cuidado de salud oportuno y respetuoso en casos de aborto terapéutico en niñas y adolescentes con embarazos no deseados por violación sexual en Perú y brindar soluciones a éstas bajo el Enfoque de Derechos Humanos del Paciente (EDHP).
Dificultad en la aplicación de la atención paliativa en un servicio de medicina interna en Murcia, España
Authors: Sabater Martinez Violeta
Published: February 2025

El envejecimiento de la población, junto a la dependencia y comorbilidades han provocado que los cuidados en fase avanzada de enfermedad tomen una especial relevancia. En muchas ocasiones los sanitarios no se sienten lo suficientemente formados para poder brindar unos cuidados paliativos de calidad, que ofrezcan una atención activa e integral. Es por ello que los objetivos del presente estudio fueron: a) averiguar si los profesionales sanitarios tienen conocimientos específicos en cuidados paliativos; b) analizar si el equipo sanitario conoce el plan de actuación que debe realizar con un paciente en fase terminal; c) identificar si el equipo de sanitarios dispone de herramientas para los cuidados al final de la vida.  Han participado 58 profesionales sanitarios del Hospital Los Arcos del Mar Menor a los que se les pasa el cuestionario validado Palliative Care Difficulties Scale (PCDS)” con el fin de averiguar su opinión sobre los cuidados paliativos. Aparecen diferencias significativas (p<0.05) en las siguientes variables: a) Es difícil establecer una comunicación entre los miembros del equipo, respecto al alivio de síntomas del paciente; b) Cuando un paciente expresa ansiedad, es difícil darle una respuesta; c) No hay equipos de expertos a los que consultar, sobre el control de síntomas del paciente en domicilio. Entre las conclusiones destaca que existen carencias en la puesta en práctica de forma unánime y homogénea de los protocolos en cuidados paliativos, por lo cual sería necesario que se implementen programas de formación continuada para el personal sanitario y que se desarrollen procedimientos normalizados.
Voicing the Cultural Trauma of the Māori Community in Bugs by Whiti Hereaka (2013)
Authors: Berthiot Marine
Published: February 2025

Abstract: Aotearoa New Zealand children's literature rose as a genre per se from the 1950s onwards. Before the Second World War, Kiwi children and teenagers had access to British and American books and magazines, but were not represented in the texts they were given to read. The colonial heritage of children's literature continues to shape certain ethnic prejudices to this day, affecting the Indigenous people in particular, and non-whites in general. Whiti Hereaka (a Māori author of Ngāti Tūwharetoa, Te Arawa, Ngāti Whakaue, Tūhourangi, and Pākehā descent) is an award-winning author, whose novels Bugs and Legacy , respectively, received the 2013 New Zealand Book Honour Award and the 2019 New Zealand Book Award for Young Adult Fiction. Bugs can be read as a crossover text as its targeted audience is aged between fifteen and thirty (and more), and as it questions the intercultural relationships between Māori and Pākehā in Aotearoa New Zealand. Readers are indeed invited to follow a teenage Māori anti-heroine during her last year of high school, thus experiencing racial, sexist, and classist discriminations through her eyes. This article examines how Whiti Hereaka expresses the cultural trauma of the Māori community in Bugs . After studying the YA novel as the coming-of-age story of a Māori high school girl, I will focus on Hereaka's construction of a "dual address" to her readers, before analyzing the way Māori and Pākehā oral literary traditions intermingle in the text, opening a space for Māori teenagers to build a fairer society in Aotearoa New Zealand.
"The Feminist Coven Did It": Nigerian Women's Feminist Leadership and Coalition Against Police Brutality during the 2020 #EndSARS Protests
Authors: Alozie Bright
Published: February 2025

Abstract: The 2020 #EndSARS protest—a movement against police brutality and state violence in Nigeria—is an excellent locale for the historical study of African women's activism and contributions to social movements. Young Nigerian women actively spearheaded this movement. Employing oral history methods, social media, and other primary sources, I place these women at the center of the narratives surrounding the #EndSARS protest. Their exceptional leadership and coordination contributed to the success of the most extensive youth-led protests in Nigeria's contemporary history. In locating their individual and collective activism, I argue that history provided the roadmap for how they did effective activism since the protesters were not just reenacting age-old strategies of dissent but were also consciously invoking history as they did so. The invocation of history was one strategy for building their feminist coalition, besides hashtag activism and on-the-ground resistance and support. I also argue that the radical consciousness of Nigerian women during the protest impacted the meaning of Nigerian feminism and feminist leadership in movements against state violence. The movement also reflected an Afrofuturistic society, which underscored citizens' desperation for a better and more just society. Historicizing Nigerian women's voices contributes to the "making memory" of their lived experiences during that momentous period. By reframing the lens of the #EndSARS protest to feminist leadership, I make important interventions in Black/African feminist literature, feminist theories of leadership, and to scholarship that engages with the long history of women's activism and mobilizations in Nigeria.
Through the Eyes of Ladies-in-Waiting: Female Spectatorship and the Power of Knowledge in the Genji Scrolls
Authors: Peterson Joannah
Published: February 2025

Abstract: Scholars have long noted the essential role of nyōbō , or ladies-in-waiting, in The Tale of Genji . Although rarely taking center stage, these seemingly peripheral characters have been understood to constitute networks through which information could flow, often “offstage,” thus setting in motion much of the tale’s drama and propelling the narrative forward. This article examines the prominence of ladies-in-waiting in the tale’s earliest extant adaptation, the mid-twelfth-century Genji Scrolls . My study, employing both art historical and literary textual analyses, demonstrates that the nyōbō ’s function informs their treatment and placement in the scrolls’ images as well as several aspects of the work’s visual structure. It also adds to scholarship on voyeurism in Genji by noting the ways in which information gathering is shown to be multisensory rather than limited to the use of vision and to be the purview of female as well as male characters. Finally, paralleling the role of nyōbō as points of connection in the tale’s narrative structure, I show how images of the ladies-in-waiting in the Genji Scrolls tie together disparate elements of the tale and also reveal hidden meanings to astute readers and viewers.
"not a place but a process": Dana Spiotta's Utopian Fictions
Authors: Bernstein Stephen
Published: February 2025

Abstract: Dana Spiotta's repeated use of upstate New York locations in her fiction has occasionally drawn on the history of nineteenth-century utopian communities that flourished in the area. Though the experiences Spiotta's characters have in these locations are far from utopian, the novels that emphasize such sites to a lesser degree ( Stone Arabia, Innocents and Others ) show greater faith in radical improvement, but only on the individual level. As several contemporary utopian theorists suggest, utopia is a process rather than a definable site. Thus it is finally only through mental process that Spiotta's characters can arrive, however briefly, at something like utopian transcendence.
Forms of Death and the Death of Form in Contemporary Black Fiction
Authors: Ivry Henry
Published: February 2025

Abstract: In this article, I explore how death has become one of the determinant logics of contemporary Black fiction as authors attempt to anticipate the insatiable desire of white audiences to witness Black people dying. At the same time, however, I look at how a certain subset of contemporary Black authors anticipate that market demand and undercut the very processes of reifying their work. Looking at work by Monica Brashears, Percival Everett, and Jason Mott, I explore how all three authors use satire (and, more specifically, a satire of mourning) as a way of both drawing attention to and exceeding the implied interpretive and formal framework of a white literary marketplace.
Enhanced accuracy in surface profile reconstruction in white light interferometry using the BM3D algorithm in conjunction with fast Fourier transform
Authors: Nhu Le , Doan Thong Nguyen , Hai Le Hoang
Published: February 2025

The application of White Light Interferometry (WLI) has been increasingly widespread across various fields for high-precision surface profile measurements. The advantages of this method include rapid measurement time, non-contact operation, and the ability to measure a wide range of surfaces. The accuracy of the measurement depends on the quality of the interference fringe signals captured by the camera. In this study, we propose a novel approach to WLI signal processing consisting of two main steps. The first step involves preprocessing the noise in individual interference fringe images to obtain cleaner and more accurate fringe patterns, thereby improving the quality of axial interference signals. The second step focuses on processing axial interference signals using advanced methods to extract precise surface height information. For the preprocessing step, the BM3D (Block-Matching and 3D Filtering) algorithm was chosen due to its effectiveness in image denoising. In the second step, we employed the Fast Fourier Transform (FFT) method to reduce noise in axial interference signals, combined with a fitting algorithm to accurately determine the height of surface points. The proposed method has demonstrated significant effectiveness in improving measurement accuracy. This is validated through various simulated surface profiles, showing an accuracy improvement of over 40% compared to cases without the proposed algorithm. Additionally, our approach can serve as a foundation for further interference signal processing algorithms to achieve even higher accuracy.

Humans and animals use multiple control systems for decision-making. This involvement is subject to meta-cognitive regulation – as a form of control over control or meta-control. However, the nature of this meta-control is unclear. For instance, Model-based (MB) control may be boosted when decision-makers generally lack confidence as it is more statistically efficient; or it may be suppressed, since the MB controller can correctly assess its own unreliability. Since control and metacontrol are themselves subject to the influence of neuromodulators, we examined the effects of perturbing the noradrenergic and dopaminergic systems with propranolol and L-DOPA, respectively. We first administered a simple perceptual task to examine the effects of the manipulations on meta-cognitive ability. Using Bayesian analyses, we found that 81% of group M-ratio samples were lower under propranolol relative to Placebo, suggesting a decrease of meta-cognitive ability; and 60% of group M-ratio samples were higher under L-DOPA relative to Placebo, considered as no effect of L-DOPA on meta-cognitive ability . We then asked subjects to provide choices and confidence ratings in a two-outcome decision-making task that has been used to dissociate Model-free (MF) and MB control. MB behavior was enhanced by propranolol, while MF behavior was not significantly affected by either drug. The interaction between confidence and MF/MB behavior was highly variable under propranolol, but under L-DOPA, the interaction was significantly lower/higher relative to Placebo. Our results suggest a decrease in metacognitive ability under the influence of propranolol and an enhancement of MB behavior and meta-control under the influence of propranolol and L-DOPA, respectively. These findings shed light on the role of NE and DA in different aspects of control and meta-control and suggest potential avenues for mitigating dysfunction.
What are Deaf sign language users’ experiences as patients in healthcare services? A scoping review
Authors: Rogers Katherine D. , Lovell Karina , Bower Peter , Armitage Christopher J. , Young Alys
Published: February 2025

Background

Deaf people who use a signed language experience poorer physical and mental health outcomes and inequalities in access and delivery of health services.

Objectives

A scoping review was conducted to identify and synthesise current knowledge on the perspectives of Deaf people and their experience of healthcare.

Search strategy

Databases PsycINFO, PubMed, Web of Science, and CINAHL were used for this review.

Inclusion criteria

Any studies internationally of any design that involve Deaf signing populations that reported on patient experience within healthcare settings from a Deaf perspective were included in the review.

Data extraction and synthesis

The abstract, title, and initial screening was followed by full text screening completed by two screeners independently. The extracted data included descriptive data and study findings. The Crowe Critical Appraisal Tool (CCAT) was applied, and findings were summarised using narrative synthesis.

Main results

Across the 51 included papers, problems with language, communication and interaction featured prominently. Failure to meet Deaf people’s needs has adverse impacts; examples of these include negative emotional state, disempowerment through lack of knowledge, and lack of confidence in healthcare systems.

Discussion and conclusions

The review uniquely focused on data generated from Deaf people regarding their experience, rather than third party commentary. It confirmed a less than optimal Deaf patient experience, clinical impacts of poor experience, and negative patient and healthcare systems outcomes. This supports the case for a reliable and valid measure in a signed language to capture Deaf patients’ experience in healthcare.
Effects of prolonged aerobic exercise and training intensity on memory cognition

This study aims to explore whether the impact of varying aerobic exercise intensities on knowledge acquisition is influenced by exercise intensity and gender. The results lay the groundwork for selecting suitable aerobic exercise intervention programs, considering exercise intensity and gender, to enhance knowledge acquisition. Employing a mixed-design approach, a sample of 569 college students engaged in 8 weeks of aerobic exercise sessions with moderate and low intensity, incorporating basketball and badminton. Knowledge acquisition effects were assessed using questionnaires targeting distinct knowledge levels. Declarative and procedural knowledge levels across different acquisition types were evaluated pre and post-exercise intervention for the low-intensity, moderate-intensity, and control groups. The findings reveal that both moderate and low-intensity aerobic exercises distinctly and positively impact college students’ knowledge levels, with no discernible gender-related alterations.

After having lived as the dominant human species in Europe for over 200 kyr, Homo neanderthalensis (the Neanderthals) disappeared around 40 kyr BP (Before Present) Higham T (2014). Competition with Homo sapiens, who arrived in Europe around the same time, is often invoked to explain this extinction. Others have argued that climate change may have reduced the living space of this population making its disappearance more rapid. In order to test the climate change hypothesis we modelled the Neanderthals’ ecological niches in Europe between 90 and 50 kyr BP through paleoenvironmental reconstructions and Eco-Cultural Niche Modelling. We selected five environmental variables (orographic height, mean annual precipitation, mean temperature of the coldest month, carrying capacity and friction, see below) from climate model simulations of 5 periods between 90 and 50 kyr BP in Europe. We used Structural Similarity (SSIM) index to compare the probability maps of suitable niches to Neanderthals performed by Maxent. After a strong initial environmental change between the first (P1 = 90 to 83 kyr BP) and second (P2 = 83 to 69 kyr BP) periods, our results show that large areas highly suitable for Neanderthal occupation persisted across Europe. As our results show an increase/stability of the areas suitable to Neanderthals, the question of the cause of the decrease or displacement of the Neanderthal population towards southern Europe after this climatic change remains open.
Author name disambiguation based on heterogeneous graph neural network

Published: February 2025

With the dramatic increase in the number of published papers and the continuous progress of deep learning technology, the research on name disambiguation is at a historic peak, the number of paper authors is increasing every year, and the situation of authors with the same name is intensifying, therefore, it is a great challenge to accurately assign the newly published papers to their respective authors. The current mainstream methods for author disambiguation are mainly divided into two methods: feature-based clustering and connection-based clustering, but none of the current mainstream methods can efficiently deal with the author name disambiguation problem, For this reason, this paper proposes the author name ablation method based on the relational graph heterogeneous attention neural network, first extract the semantic and relational information of the paper, use the constructed graph convolutional embedding module to train the splicing to get a better feature representation, and input the constructed network to get the vector representation. As the existing graph heterogeneous neural network can not learn different types of nodes and edge interaction, add multiple attention, design ablation experiments to verify its impact on the network. Finally improve the traditional hierarchical clustering method, combined with the graph relationship and topology, using training vectors instead of distance calculation, can automatically determine the optimal k-value, improve the accuracy and efficiency of clustering. The experimental results show that the average F1 value of this paper’s method on the Aminer dataset is 0.834, which is higher than other mainstream methods.
