Beyond Disability and Disaster: The Affect of Debilitation in Indra Sinha’s Animal’s People
Authors: Chandrashekhar Shwetha
Published: February 2025

Abstract: This article demonstrates how Indra Sinha’s novel Animal’s People (2007) conceptualizes debilitation as an affective post- disaster condition. The novel does this by foregrounding Animal’s unpleasant feelings, involuntary bodily responses, and unruly sexual urges. Building on Jasbir K. Puar’s conception of debilitation, I argue that Sinha not only obfuscates the ability- disability binary but also highlights the porosity between concepts such as the human, animal, and subhuman by depicting debilitation as a consequence of invisibilized forms of violence and injustice that are stretched across vast swathes of time and space. In illustrating the complex affective dynamics between Animal and other characters, the novel portrays disidentification as a response of marginalized and minoritarian subjects to the debilitation engendered by neoliberal capitalism, thereby offering readers a new way of grasping the intersections between disability, masculinity, and sexuality. Further, I suggest that Sinha captures the persistence of debilitation in Khaufpur, the fictional city in which the novel is set, through the ever-present and recurrent possibility of apocalypse. Against that persistence, Animal’s People balances the possibility of subaltern solidarity. The novel thereby calls for a more nuanced understanding of debilitation in the twenty-first-century Global South.
“Told in Conference Style”: Narrative Form and the Conceptualisation of Culture in Woman of the Aeroplanes
Authors: Cartwright Penny
Published: February 2025

Abstract: Despite the frequent exclusion of African literature from formalist discussions, this article considers the role of narrative form in helping to forward different theoretical conceptualisations of culture in Kojo Laing’s Woman of the Aeroplanes (1988). It argues that different narrative features provide aesthetic corollaries for two distinct conceptualisations of culture that circulated in nation- building projects following independence: culture as extractible national resource and culture as unfolding historical process. It argues that Woman of the Aeroplanes both explicitly reflects on these competing conceptualisations of culture as part of its thematic content and formally interrogates them via techniques of chronotopic metaphor and narrative dynamism. These narrative features reveal the “inner logics” of concepts (Ngũgĩ 9), making form critical to the evaluation of different conceptualisations of culture. The article brings together formalist readings with conceptual debates from the mid-twentieth century “cultural policy moment” (Martin 1340) to demonstrate the theorizing potential of narrative form as well as Laing’s distinctive contributions to this area.
"It's Not About Blood, It's About Who Shows Up for Me": Black College-going Foster Youth Disrupting Family Privilege and Creating Chosen Family Networks
Authors: Whitman Kenyon Lee , Lopez Kizzy
Published: February 2025

Abstract: Utilizing narrative inquiry, this study collected individual interviews to understand how nine Black students who experienced the carceral nexus of foster care navigated college. Utilizing BlackCrit and Community Cultural Wealth as a theoretical framework, findings show how the foster care system was dehumanizing and stripped students of their family privilege. Findings also show how the students resisted the foster care system by (re)defining family in their own way by creating chosen family. Lastly, findings show the unique ways their chosen families provided the love, care, and capital needed to thrive in college, they leaned on their chosen family as support throughout their college experiences. Implications focus on the ways in which family privilege operates in higher education and how it disadvantages Black foster youth. Recommendations focus on creating more inclusive and equitable spaces for Black students with foster care histories.
Assessment Of A Health System-Integrated Children's Savings Account and Financial Coaching Program Serving Low-Income Moms and Babies in Texas
Authors: Olmstead Todd A , Rosen Laura , Hole Michael K
Published: February 2025

Abstract: Families living in poverty with young children are particularly vulnerable to poor health outcomes. This study used a randomized controlled trial to analyze the impact of Early Bird (EB), a novel health system-integrated program that provided financial incentives to low-income mothers for achieving healthy milestones. Participants randomized to the EB condition received contributions in a tax-advantaged children's savings account (CSA) for attending a maternal six-week postpartum check-up ($25), a pediatric dental visit by age 12 months ($75), six well-check visits by age 15 months ($75), two financial coaching sessions ($30), and enrolling in the EB program and opening a CSA ($250). We found that Early Bird increased the likelihood that mothers attended a financial coaching session. We found no evidence of an increase in the likelihood of completing any of the medical milestones. Future work should examine whether larger contributions to CSAs might incentivize mothers to achieve the medical milestones.

Published: February 2025

Abstract: The Grady Heart Failure Program (GHFP), based in a safety-net hospital, is an outpatient program that follows heart failure hospitalization. The 2018 GHFP added a community health worker, patient liaison, and mobile integrated health home visits to reduce socioeconomic barriers to treatment. Important outcomes for the GHFP included the program cost and patient follow-up visits within seven days of hospital discharge. We calculated the difference in 30-day related readmission between 2017 and 2018 to assess pre-post program effectiveness. Patient follow-up visits within seven days increased from 63.7% in 2017 to 65.6% in 2018. Related 30-day readmissions declined from 15.5% in 2017 to 13.1% in 2018. Compared with 2017, the incremental program cost per related 30-day hospital readmission averted was $7,955 in 2018. The expanded GHFP is potentially cost-saving from the perspective of the hospital-provider based on the inpatient cost saved from a heart failure readmission averted.
What is Unspoken: The Discomfort Experienced by Pediatric Resident Physicians Delivering Racially Discordant Clinical Care
Authors: Darwiche Sabrina M. , Kuo Anda K. , Schudel Christine , Morales Maya , Chan Helen Iat Chio , Long Dayna
Published: February 2025

Abstract: A diverse physician workforce is imperative to addressing health inequities, but few physicians identify as Black or Hispanic. Therefore, this study used the social constructionism framework to explore pediatric residents' perceptions of race in medical encounters. A qualitative study of 47 trainees at a tertiary care center revealed the following: (1) racism, not race, influences health; (2) trainee perceptions around race create feelings of discomfort during some racially discordant patient encounters, while they were a source of comfort for trainees of color during concordant encounters; and (3) trainee perceptions around race in racially discordant clinical encounters may result in a change in clinical practice. While participants expressed awareness that racism drives health disparities, they had limited understanding of how their interactions might further perpetuate disparate health outcomes for patients of color. This emphasizes the need to support anti-racism competencies in medical education and increase workforce diversity in health care.

The combination of highly dynamic network services requiring stringent quality of service (QoS), especially in terms of end-to-end (e2e) delay, together with capital and operational cost reduction cannot be faced using centralized software-defined networking (SDN) solutions only. In particular, such expected dynamicity requires autonomous near-real-time operation fed with pervasive telemetry to make per-service decisions that ensure the committed QoS, while reducing overprovisioning as much as possible. In this paper, we propose a distributed control architecture based on multi-agent systems (MASs) to assist the SDN controller in the control of network services near-real-time. Per-traffic flow telemetry data are collected from the packet nodes, distributed through the agents in the control plane, and analyzed to assure performance and to anticipate any degradation. Measurements feed flow agents, which are based on deep reinforcement learning (DRL) models, to make routing decisions aiming at ensuring flow performance. In the case when QoS degradation is detected, we propose algorithms to analyze its cause, which can be a result of some bottleneck in the network. We show how the latter is detected and additional capacity is requested of the SDN controller, which in turn creates an optical bypass to provide additional capacity. The proposed solution is demonstrated experimentally on a federated testbed connecting UPC and CNIT premises. Focused first on the control plane, the feasibility of the proposed architecture and workflows is experimentally assessed. After that, the performance of the near-real-time operation is evaluated at the data plane to verify that the maximum e2e delay is not exceeded for multiple flows, showing the effectiveness of predictive QoS evaluation together with infrastructure and service reconfiguration.
Routes to broadband laser chaos with dynamics switching in a 1550-nm VCSEL laser subjected to optical feedback

Published: February 2025

Vertical-cavity surface-emitting laser (VCSEL) has received much attention due to its high modulation response bandwidth, two linear polarization modes, and easy integration. The fundamental characteristics of lasers can be observed by simple optical feedback. Here, we experimentally investigate the dynamical characteristics in a 1550-nm VCSEL subjected to mirror optical feedback. The distribution of dynamics for different bias currents and feedback strength is in detail unveiled. Four different dynamic routes to laser chaos are observed at different bias currents. As the bias current increases, the route to chaos becomes complex. Apart from the well-known stable state, quasi-periodic state, chaotic state, and two previously reported dynamics switching phenomena, the dynamics switching between intermittently quasi-periodic state and quasi-periodic state is observed at a high bias current. Additionally, the laser chaos at different bias currents is also comparatively studied. The chaos bandwidth can reach 18 GHz. The systematic investigation provides the basis for utilizing the broadband laser chaos and understanding the nonlinear dynamics in VCSELs.
Load capacitance matching for resonant frequency adjusting-based multi-quartz tuning fork-enhanced laser spectroscopic sensing
Authors: Ma Hanxu , Qiao Shunda , He Ying , Zhang Chu , Ma Yufei
Published: February 2025

What we believe to be a novel load capacitance matching method is proposed for adjusting the resonant frequency of a quartz tuning fork (QTF) in a multi-QTF-based laser spectroscopy gas sensor for the first time. A sensing system integrating quartz-enhanced photoacoustic spectroscopy (QEPAS) and light-induced thermoelastic spectroscopy (LITES) was constructed to validate the proposed method. In this system, the QEPAS module consists of QTF1, while the LITES module is based on QTF2. Methane was chosen as the target gas to evaluate both the reliability of the method and the sensor's performance. Without frequency matching, the difference in resonant frequencies between QTF1 and QTF2 was 6.67 Hz, resulting in a superposition efficiency of only 33.7% for the QEPAS-LITES sensor. When the load capacitance matching method was applied, the load capacitance of QTF2 was adjusted to bring its resonant frequency closer to that of QTF1. This successfully matched the resonant frequencies of both QTFs, improving the superposition efficiency to 98.7%. The QEPAS-LITES sensor utilizing the load capacitance matching method demonstrated a strong linear concentration response. Additionally, long-term stability was evaluated through Allan deviation analysis. With an average time of 100 s, the minimum detection limit of the QEPAS-LITES sensor system was improved to 5.91 ppm.
Integrating multiscale mathematical modeling and multidimensional data reveals the effects of epigenetic instability on acquired drug resistance in cancer
Authors: Wang Shun , Lei Jinzhi , Zou Xiufen , Jin Suoqin
Published: February 2025

Biological and dynamic mechanisms by which Drug-tolerant persister (DTP) cells contribute to the development of acquired drug resistance have not been fully elucidated. Here, by integrating multidimensional data from drug-treated PC9 cells, we developed a novel multiscale mathematical model from an evolutionary perspective that encompasses epigenetic and cellular population dynamics. By coupling stochastic simulation with quantitative analysis, we identified epigenetic instability as the most prominent kinetic feature related to the emergence of DTP cell subpopulations and the effectiveness of intermittent treatment. Moreover, we revealed the optimal schedule for intermittent treatment, including the optimal area for therapeutic time and drug holidays. By leveraging single-cell RNA-seq data characterizing the drug tolerance of lung cancer, we validated the predictions made by our model and further revealed previously unrecognized biological features of DTP cells, such as cell autophagy and migration, as well as new biomarker genes of therapeutic tolerance. Our work not only provides a paradigm for the integration of multiscale mathematical models with newly emerging genomics data but also improves our understanding of the crucial roles of DTP cells and offers guidance for developing new intermittent treatment strategies against acquired drug resistance in cancer.

Published: February 2025

Introduction

The strong association between obesity and chronic kidney disease (CKD) has been empirically validated, yet traditional measures like the Body Mass Index (BMI) fail to accurately assess the extent of obesity due to CKD’s characteristics, such as reduced muscle mass and increased visceral fat. This study investigates the association between CKD and several anthropometric indices, including A Body Shape Index (ABSI), Body Roundness Index (BRI), Waist-to-Height Ratio (WHtR), and the Conicity Index (C-index), to determine their predictive capabilities.

Methods

Based on the datasets from the National Health and Nutrition Examination Survey (NHANES) 2009–2018, weighted multivariable regression analyses were carried out to examine the independent relationship between two anthropometric indices and CKD. Also, subgroup analyses, restricted cubic spline regression (RCS), and receiver operating characteristic curve analysis were conducted for further data analyses.

Results

A total of 24,162 participants were enrolled in this study. After adjusting for confounding factors, ABSI, BRI, WHtR, and the C-index were significantly associated with an increased risk of CKD, while BMI was not. Height showed a protective effect against CKD. ABSI and the C-index demonstrated the highest areas under the curve (AUCs), indicating superior predictive capabilities compared to traditional measures like BMI and waist circumference (WC). Subgroup analyses revealed significant interactions between the anthropometric indices and factors such as age, disease status, dietary intake, and physical activity levels.

Conclusions

This study highlights the significant associations between various anthropometric indices (including ABSI, BRI, WHtR, and C-index) and the risk of CKD. ABSI and the C-index demonstrated the strongest predictive capabilities for CKD, with the highest AUC values.
Acute fatigue in indoor court-based team sports: A systematic review
Authors: Clark Anthony , Heyward Omar , Paul Lara , Jones Ben , Whitehead Sarah
Published: February 2025

Fatigue in team sports has been widely researched, with a number of systematic reviews summarising the acute (i.e., within 48-hours) response in outdoor sports. However, the fatigue response to indoor court-based sports is likely to differ to outdoor sports due to smaller playing fields, harder surfaces, and greater match frequencies, thus should be considered separately to outdoor sports. Therefore, this study aimed to conduct a systematic review on acute fatigue in indoor court-based team-sport, identify methods and markers used to measure acute fatigue, and describe acute fatigue responses. A systematic search of the electronic databases (PubMed, SPORTDiscus, MEDLINE and CINHAL) was conducted from earliest record to June 2023. Included studies investigated either a physical, technical, perceptual, or physiological response taken before and after training, match, or tournament play. One-hundred and eight studies were included, measuring 142 markers of fatigue. Large variability in methods, fatigue markers and timeline of measurements were present. Cortisol (n =  43), creatine kinase (n =  28), countermovement jump (n =  26) and testosterone (n =  23) were the most frequently examined fatigue markers. Creatine kinase displayed the most consistent trend, increasing 10–204% at 24-hours across sports. There is large variability across studies in the methods and markers used to determine acute fatigue responses in indoor court-based team sports. Future researchers should focus on markers that display high reliability and transfer to practice. The robustness of studies may be increased by ensuring appropriate methods and timescale of fatigue marker measurement are used. Further research is required to determine which combination of markers best describes a fatigue response.
Interval price prediction of livestock product based on fuzzy mathematics and improved LSTM
Authors: Ma Weimin , Peng Lingling , Chen Hu , Yan Haisheng
Published: February 2025

Livestock product prices serve as a barometer and bellwether for the agricultural market. However, traditional point prediction techniques focus mainly on tracking or fitting, resulting in limited information and challenges in evaluating the uncertainty of future prices. A comprehensive livestock price prediction model with joint point and interval prediction capabilities is proposed, with fuzzy mathematics and long short-term memory. Three main steps are taken: (1) data composition and reconstruction, to extract a set of relatively stationary subsequence components by complementary ensemble empirical mode decomposition (CEEMD) from original signal, and divide these components into three groups according to fuzzy entropy (FE) value. (2) characteristics categorization, determining the lower bound, mean, and upper bound of the rebuilt data via fuzzy information granulation (FIG) to better characterize the price fluctuation range. (3) price prediction, including point and interval predictions with attention mechanism long short-term memory (AM-LSTM). An empirical study was conducted on the weekly price data of pork, beef, and mutton in China from 2009 to 2023, incorporating discussions on different embedding dimensions, prediction step, fuzzy granulation window sizes, decomposition techniques, and prediction algorithms. The results indicate that the proposed interval prediction model can not only achieve high accuracy in point prediction, but also better capture price change intervals.

Published: February 2025

Background and Aim: Tryptophan (Trp), a precursor of serotonin, plays a critical role in cognitive and emotional processes. Its metabolism through serotonin and kynurenine pathways impacts neuropsychiatric functions and lipid metabolism. This study investigates Trp’s effects on the behavioral, physiological, and molecular parameters of aging female wild-type (WT) and heterozygous tryptophan hydroxylase-2 (HET) mice.

Materials and Methods: A 68-day experiment was conducted on 13-month-old WT and HET mice. Groups received either distilled water or Trp supplementation (400 mg/kg/day). Behavioral tests (Open Field, Elevated Zero Maze, Forced Swim, and Extrapolation Escape Task) assessed locomotion, anxiety, and cognition. Physiological assessments included body composition through NMR relaxometry, lipid histology, serotonin content in the brain (ELISA), and serotonergic gene expression (RT-PCR). Blood biochemistry and organ weights were also analyzed.

Results: Trp supplementation reduced growth rates and adipose tissue while increasing muscle mass in both genotypes, more markedly in HET mice. Behavioral tests revealed a decrease in anxiety and enhanced cognitive performance in HET+Trp mice but an increase in immobility. Trp increased brain serotonin content in HET mice and altered serotonergic gene expression. Histological studies showed hepatoprotective effects in HET+Trp mice, reducing liver lipid infiltration compared to WT+Trp mice.

Conclusion: Trp exhibited genotype-specific effects, with HET mice showing anabolic, hepatoprotective, and neuropsychiatric changes. These findings highlight Trp’s potential in neuro-nutrition for conditions like depression and cognitive decline. Further studies are needed to explore Trp’s metabolic pathways and their implications for personalized dietary interventions.

Keywords: aging, behavioral tests, lipid metabolism, neuro-nutrition, neuropsychiatry, serotonin, tryptophan hydroxylase-2 heterozygosity, tryptophan.
Objects of Tourist Desire – Consuming Museum Souvenirs from Objects on Display
Authors: Waizbort Karla Estelita Godoy , Da Silva Vidal Leonardo , Fonseca Filho Ari da Silva
Published: February 2025

Purpose – Souvenirs are objects of desire often consumed when traveling. In museum stores, one finds what is called “museum souvenir” – which reproduces, in some way, works of art and other museum objects. In this sense, the link between the consumption of museum souvenirs and the relationship between tourists and objects on display was investigated. The research aimed to analyze the consumption of this type of souvenir in museum stores, in theoretical dialogue with the theme of souvenirs and their consumption in tourism, and with the concepts of “aestheticization” (Lipovetsky; Serroy, 2015) – appropriation of beauty as a consumer good –, and “technical reproducibility” (Benjamin) – the substitution of the unique existence of the work by a serial existence.
Design/methodology/approach – It is thus clear that subjects are not separated from their materialities (Miller, 2013) and that souvenirs are part of the universe of material things that make up the materialities of tourism. The ethnographic-based field research took place in museums in the city of Rio de Janeiro, adopting systematic observation and interviews.
Findings – Results point to the existence of a symbolic dimension in the relationship between the consumption of museum souvenirs and the exhibition visited, as they are connected to the experience and aesthetic fruition of tourists with works on display.
Research limitations/implications – Adopting souvenirs as an object of study from this perspective has enabled the expansion of analyses on their consumption by tourists, identifying gaps of scientific interest and projecting relevance to the research.
Practical implications – Other public profiles interested in souvenirs of different types and in consuming them for different purposes and in different places cannot be ignored. However, this qualitative research identified tourists who clearly demonstrated a desire to consume these categories of museum souvenirs.
Originality/value – The approach gives the article an innovative character and possibilities for theoretical and methodological contributions to future studies, such as theoretical dialogues with authors from the field of anthropology, with the existing theory on souvenirs and their consumption in tourism. Furthermore, it stands out from the most recurrent perspectives found in the literature on the subject in the area of ​​tourism, as it seeks to deepen the understanding of the production of meanings.

Este artigo tem por objetivo problematizar os discursos sobre o espaço ocupado pelas mulheres na capoeira, bem como os sentidos atribuídos à corporalidade feminina neste universo marcadamente masculino. Essa discussão considera as influências do vínculo social, político e de resistência da capoeira em sua relação com as culturas afro-brasileiras, como também a influência da perspectiva esportiva adotada durante o projeto nacionalista do Estado Novo. Em contrapartida à versão esportiva baseada na performance física, apresento os fundamentos da malícia e a concepção do corpo-capoeira como modo alternativo de uma performatividade oriunda das culturas afrodiaspóricas. Essa análise também demanda a compreensão das interseccionalidades de raça, gênero e classe e se apoia nos preceitos teóricos dos estudos decoloniais e dos feminismos negros. A partir dessa elaboração teórica, proponho a análise de duas notícias selecionadas da internet, veiculadas entre os anos de 2022 e 2023, sobre as construções discursivas atuais que perpassam a participação feminina na capoeira. Encerro o trabalho com a compreensão de que a análise da produção de subjetividades a partir do corpo-capoeira da mulher requer estudos aprofundados e destaco a importância de pautar essa discussão em consonância com os princípios das culturas e da herança afro-brasileiras.

Mulheres negras estão retornando ao alisamento capilar: esse é o discurso que permeou diversos dos principais portais de notícias do país entre 2021 e 2024 e é sintomático daquilo que se tem denominado no Brasil de “liberdade capilar”. Nesse cenário, para lançar luz sobre as complexidades subjacentes aos discursos que tematizam o cabelo crespo, este artigo investiga o deslocamento discursivo entre os movimentos de transição capilar e liberdade capilar no Brasil contemporâneo, utilizando pressupostos teóricos dos Estudos Discursivos Foucaultianos, especialmente os conceitos sobre poder/saber, resistência e suas múltiplas manifestações nos discursos. Sobre o corpus, o artigo concentra-se na análise de enunciados encontrados em notórias revistas brasileiras, revelando o modo como as dinâmicas de saber e poder produzem e transformam os discursos sobre o cabelo crespo no Brasil. A discussão explora a complexidade desses discursos, destacando as pressões sociais e midiáticas que continuamente geram novas formas de poder e, consequentemente, novas formas de resistência.

La necesidad de tratamiento en el internamiento psiquiátrico penal: hacia la superación de los modelos penitenciarios
Authors: Giraldi Angelo
Published: February 2025

El artículo analiza las criticidades y propone poner en marcha, tanto teórica como concretamente, un proceso de superación de los actuales modelos de internamiento psiquiátrico penitenciario, en aras de la creación de estructuras principalmente sanitarias, que engloben oportunamente las exigencias de seguridad y las necesidades asistenciales de los que ostentan la condición de reos peligrosos y, a la vez, de pacientes. La propuesta se desarrollará mediante el análisis del “nuevo” modelo de internamiento psiquiátrico implantado en Italia, donde hace algunos años se llevó a cabo el proceso de conversión de los antiguos Ospedali Psichiatrici Giudiziari (OPG: hospitales psiquiátricos judiciales) en las Residenze per l’Esecuzione delle Misure di Sicurezza (REMS: residencias para la ejecución de las medidas de seguridad), cuya “sanitarización” ha conllevado resultados beneficiosos y, a la vez, aspectos conflictivos.

Published: February 2025

AA2024 is widely employed within the aerospace sector; nevertheless, its susceptibility to pitting upon exposure to chloride ions presents a notable challenge. This investigation proposes an in-situ co-precipitation technique for effectively sealing the anodic oxide layer on the AA2024 substrate by nickel–aluminum layered double hydroxides (LDH) conversion coating. Given the lack of reported data concerning the correlation between the nucleation/growth behavior and the anti-corrosion performance of NiAl-LDH coatings, the current research aimed to investigate the effect of synthesis conditions including temperature and pH on the morphology and nucleation of LDH nanoplatelets, as well as the corrosion resistance of prepared coatings. Field-emission SEM, atomic force microscopy, X-ray diffraction analysis, electrochemical measurements, Raman, FT-IR, and X-ray photoelectron spectroscopy were utilized to study the behavior of coatings. The results indicated that the prolonged nucleation/growth stage of synthesized NiAl-LDH nanoplatelets at pH 7.5 improves the electrochemical performance through providing a compact LDH coating.

Five different BM containing 0, 25, 50, 75 & 100 ppm SiO2 named as BM0, BM25 BM50, BM75, and BM100 respectively have been tested in DE. The prepared fuels have been tested on DE in terms of BTE, BSFC, EGT. Emissions study in terms of CO, CO2, HC, and NOx concentration in the flue gas. The results reveal that for BM100, BTE and EGT increased by 14.73  and 11.96 % compared to BM0, but BSFC decreased by 14.25 %. Emissions such as HC and CO decreased by 26.38  and 25 %. But CO2 and NOx increased by 9.8  and 46.15 % for BM100 compared to FD. Overall, the presence of SiO2 in the BM increases the DE performance with enhanced emission characteristics.
Approximate synthesis for LUT count reduction via probabilistic error propagation
Authors: Schlögl Thomas , Keszocze Oliver
Published: February 2025

Approximate computing is an fast developing area for resource-efficient and fast designs that trades off computational accuracy with non-functional aspects such as delay, energy requirements or area. It can be used for applications where it is acceptable to compute inaccurate results such as image processing. A lot of work has been published on approximate synthesis for ASICs. As FPGAs are becoming more prevalent, approximation techniques for this technology should be developed. Lookup tables are a scarce resource on FPGAs. Consequently, we present and evaluate multiple approaches for reducing the number of lookup tables required to implement a given design on an FPGA. Our approaches work by removing either wires or entire lookup tables from a lookup table network. We can show that our approach is faster than related work while removing a comparable number of lookup tables (more in most cases).

Terahertz magneto-plasmonics plays a crucial role in platforms for isolation and sensing applications, operating at terahertz frequencies. In spite of recent efforts to enhance magneto-optic effects using metasurfaces, the mechanism for optimizing these effects remains unclear in the terahertz regime. Here we investigate terahertz magneto-optic effects using 100 nm-thick iron slot antennas with varying widths, ranging from 20 µm to 300 nm. Interestingly, as the width of slot antenna decreases, this enhancement peaks around 1 µm, after which the effect diminishes for smaller widths. Based on the effective medium theory, the slot antennas exhibit a maximum Faraday rotation angle near the epsilon-near-zero region. Although the field enhancements in the slot become stronger with the sub-micron widths, the magneto-optic effect may decrease with increasing effective dielectric constant due to gap plasmon effects in the sub-micron region. Our findings provide essential criteria for designing ferromagnetic metasurfaces with enhanced Faraday rotations at terahertz frequencies.

In the digital age, social media platforms like Facebook, Instagram, and YouTube have emerged as powerful allies in promoting and preserving heritage sites. Focusing on the unique heritage of Bishnupur, West Bengal, India, this manuscript investigates the intricate interplay between social media and these cultural treasures. Through a comprehensive analysis of engagement metrics such as likes, shares, and comments, the study uncovers the nuanced dynamics of how online audiences connect with heritage sites. Platform-specific strategies are identified as essential for tailoring content to the strengths and preferences of each social media platform’s user base. The study also reveals the organic emergence of vibrant communities of heritage enthusiasts who unite to share their passion, experiences, and advocacy. The research emphasizes social media’s key role in promoting heritage sites and provides practical insights for optimizing platform-specific strategies, contributing to the discourse on preserving cultural heritage in the digital age.

The role of striatum in controlling waiting during reactive and self-timed behaviors

Published: February 2025

The ability to wait before responding is crucial for many cognitive functions, including reaction time tasks, where one must resist premature actions before the stimulus and respond quickly once the stimulus is presented. However, the brain regions governing waiting remain unclear. Using localized excitotoxic lesions, we investigated the roles of the motor cortex (MO) and sensorimotor dorsolateral striatum (DLS) in male rats performing a conditioned lever release task with variable delays. Neural activity in both MO and DLS showed similar firing patterns during waiting and responding periods. However, only bilateral DLS lesions caused a sustained increase in premature (anticipatory) responses, whereas bilateral MO lesions primarily prolonged reaction times. In a self-timing version of the task, where rats held a lever for a fixed delay before release, DLS lesions caused a leftward shift in response timing, leading to persistently greater premature responses. These waiting deficits were accompanied by reduced motor vigor, such as slower reward-orienting locomotion. Our findings underscore the critical role of the sensorimotor striatum in regulating waiting behavior in timing-related behaviors.

Significant StatementWaiting is essential for the temporal control of actions, as many cognitive behaviors—whether stimulus-driven or internally planned—require withholding a response until the appropriate time. However, the neural substrates of waiting remain less understood. Using targeted lesions, we identified the dorsolateral striatum as a crucial region for waiting in both reaction time and self-timing tasks. Lesions in this area caused a persistent increase in premature responses across tasks. In contrast, motor cortex lesions, despite its neurons showing similar activity patterns to the striatum during waiting, did not result in a lasting increase in premature responses; instead, they led to a long-term increase in reaction time.
Influence of User Personality Traits and Attitudes on Interactions With Social Robots: Systematic Review

Published: February 2025

Social robots are robots that can interact and communicate with people in accordance with social norms. They are increasingly implemented in various environments including healthcare, education and the service industry. Individual differences, such as personality traits and attitudes are drivers of human social behaviours and interactions. As robots are increasingly developed as social agents, the drive to develop more socially acceptable, user-centered robots calls for a synthesis of existing findings to improve our understanding how user traits and attitudes influence human-robot interactions (HRI). Understanding the role of individual differences, and their impact on lived experience, is crucial for designing interactions that are better tailored to users. Currently, it is unclear whether or how personality traits and user attitudes affect HRI, which interaction modalities are being investigated and what is the quality of existing evidence. To address these questions, we conducted a systematic search of the literature, yielding 56 articles, from which we extracted relevant findings. As some of the studies included qualitative outcomes, we used a mixed methods meta-aggregation, in which findings were grouped into categories to form more general synthesized findings. We found evidence that user personality traits and attitudes are indeed correlated with social HRI outcomes, including extraversion being associated with preferred distance from the robot, preference for similar robot personality traits, users’ impressions of robots and behavior towards robots. Our analysis also revealed that existing evidence has limitations which prevent us from drawing unambiguous conclusions, such as disparate interaction outcome measures, lack of comparison between different robots and small sample sizes. We provide a comprehensive summary of the existing evidence and propose that these findings can guide the development of research hypotheses to extend knowledge and to provide clarification where the existing literature is ambiguous or contradictory. Findings that warrant future investigation include different preferred robot behaviours based on extroversion and introversion, the impact of user traits on perceived robot anthropomorphism and social presence of the robot.
