Published: January 2025

Abstract
This study presents an investigation of the chemical composition of Aloe vera leaf tissue with a focus on the spatial distribution of compounds. The composition was studied using two mass spectrometry imaging techniques: silver-109 nanoparticles assisted laser desorption/ionization mass spectrometry imaging (109AgNPs-LDI-MSI) and laser ablation-remote atmospheric pressure photoionization/chemical ionization mass spectrometry imaging (LARAPPI/CI-MSI) and the identification was aided by ultra-high-performance liquid chromatography and ultra-high-resolution mass spectrometry (UHPLC-UHRMS) analysis. The results showed an abundance of phenolic compounds with antioxidant, antimicrobial, and anti-inflammatory properties, making it a beneficial food additive and food packaging material. Analysis of the results of mass spectrometry imaging provided information about the potential changes in metabolic pathway expression in different regions of the leaf.
Stalled disomes marked by Hel2-dependent ubiquitin chains undergo Ubp2/Ubp3-mediated deubiquitination upon translational run-off

Published: January 2025

Abstract
Stalled ribosomes cause collisions, impair protein synthesis, and generate potentially harmful truncated polypeptides. Eukaryotic cells utilize the ribosome-associated quality control (RQC) and no-go mRNA decay (NGD) pathways to resolve these problems. In yeast, the E3 ubiquitin ligase Hel2 recognizes and polyubiquitinates disomes and trisomes at the 40S ribosomal protein Rps20/uS10, thereby priming ribosomes for further steps in the RQC/NGD pathways. Recent studies have revealed high concentrations of disomes and trisomes in unstressed cells, raising the question of whether and how Hel2 selects long-term stalled disomes and trisomes. This study presents quantitative analysis of in vivo-formed Hel2•ribosome complexes and the dynamics of Hel2-dependent Rps20 ubiquitination and Ubp2/Ubp3-dependent deubiquitination. Our findings show that Hel2 occupancy progressively increases from translating monosomes to disomes and trisomes. We demonstrate that disomes and trisomes with mono- or di-ubiquitinated Rps20 resolve independently of the RQC component Slh1, while those with tri- and tetra-ubiquitinated Rps20 do not. Based on the results, we propose a model in which Hel2 translates the duration of ribosome stalling into polyubiquitin chain length. This mechanism allows for the distinction between transient and long-term stalling, providing the RQC machinery with a means to select fatally stalled ribosomes over transiently stalled ones.

Purpose:
The field of speech-language pathology has been and remains predominantly female, despite efforts aimed at increasing gender diversity. This study sought to determine if gender-based stereotype messaging influences students' perceptions of the field of speech-language pathology and if exposure to messaging with a short video would change student impressions of the speech-language pathology profession.

Method:
A total of 472 undergraduate students were recruited to participate in this study and were randomly assigned to three exposure conditions: (a) male-stereotype video, (b) female-stereotype video, and (c) no video. Student perceptions were evaluated with a survey, and participants' demographic data were collected including age, race/ethnicity, academic standing, and self-reported gender identity.

Results:
Overall, female participants expressed higher interest in the speech-language pathology profession, felt they would be more successful in an speech-language pathology career, perceived the field of speech-language pathology to have a higher social status, and were more likely to express interest in an speech-language pathology career than male participants. However, participants who viewed the male-stereotype video, regardless of gender, perceived the field of speech-language pathology as more scientific and reported that speech-language pathologists had greater autonomy in the field and had achieved a higher social status. Additionally, participants perceived the field of speech-language pathology as more masculine if they viewed the male-stereotype video and as more feminine if they viewed the female-stereotype video.

Conclusion:
The results of this work demonstrate that gender-stereotype career messaging is highly influential in student perceptions of the field and should be considered when motivating students to pursue speech-language pathology as a profession.
Empowering the adoption of blockchain‐based cryptocurrency as a payment method: A user‐friendly educational approach
Authors: Alrehaili Ahmed , White Martin , Beloff Natalia 
Published: January 2025

AbstractOrganizations are adopting technological innovations to transform payment systems due to challenges with traditional methods, such as slow speed and high fees. These challenges have prompted a shift towards blockchain‐based cryptocurrencies. However, cryptocurrency adoption for payments remains limited, especially in Saudi Arabia. This study adapts the technology acceptance model to explore cryptocurrency adoption through the blockchain‐based cryptocurrency as a payment method in Saudi Arabia (BCAP‐SA) model. Factors within the model are assessed using an experimental vignette‐task methodology and surveys. A key component is an educational package, offering comprehensive materials to explain blockchain technology. The findings confirm the reliability of surveys. Most model factors are statistically significant in influencing users’ intention to use cryptocurrency. The study finds that perceived ease of use, perceived usefulness, and perceived trust significantly impact participants’ intentions. Additionally, low transaction fees and age are the most influential factors on the technology acceptance model's core constructs. Statistical analysis indicates that decentralization and anonymity were insignificant and thus excluded from the revised BCAP‐SA model. These findings highlight the potential to enhance cryptocurrency adoption in Saudi Arabia. The study's insights can guide strategies to promote wider cryptocurrency usage in the region.

Global maximum power point tracking for photovoltaic systems under partial and complex shading conditions using a PID based search algorithm (PSA)
Authors: Azad Md Adil , Sarwar Adil , Tariq Mohd , Bakhsh Farhad Ilahi , Ahmad Shafiq , Mohamed Adamali Shah Noor , Islam Md Rasidul 
Published: January 2025

AbstractIn scenarios of partial shading, the effectiveness of power transmission within a photovoltaic system experiences a notable decline, potentially leading to hotspots within the photovoltaic array. While incorporating bypass diodes can mitigate this challenge, it may lead to numerous power peaks along the power–voltage (P–V) characteristics, thus complicating the task of maximum power tracking. Addressing this issue, using metaheuristic algorithms for maximum power point tracking (MPPT) offers promising outcomes by circumventing convergence towards local power peaks and easing the computational strain on the microcontroller. This study presents a fresh approach to MPPT technique utilizing the proportional–integral–derivative‐based search algorithm to effectively identify the MPP under varying partial shading conditions. Compared to existing methods, the proposed algorithm demonstrates superior performance in power tracking efficiency, tracking time, stability with fewer fluctuations, and achieving higher maximum power output. Evaluation against state‐of‐the‐art algorithms like particle swarm optimization and JAYA confirms the effectiveness of the proposed MPPT technique. MATLAB/Simulink software‐based analysis and its validation using real‐time analysis from the typhoon based hardware‐in‐the‐loop (HIL‐402) emulator support its efficacy.

Published: January 2025

Abstract
Introduction Adults with cochlear implants (CIs) need periodic programming of their speech processors to take advantage of alternative adjustments. However, this requires patients to attend the CI center in person.
Objectives To evaluate the feasibility of speech processor (SP) self-programming with remote assistance in CI users. To establish the characteristics of those who could benefit from self-programming.
Methods Adults with at least 1 year of experience with their CI, and whose SP was compatible with the use of the remote assistant fitting (RAF) were selected. Maps were created by the RAF from the neural response telemetry (NRT) results, evaluated in the same session with the audiologist. Patients were given 15-days to adjust to either the routine map or the NRT-based one. In the next session, the minimum and maximum stimulation levels (T- and C-levels) of all the maps were compared.
Results No statistical difference was found when comparing the T- and C-levels of the map in use, the map adjusted by RAF, and the NRT-based map created by the RAF and adjusted by the patient.
Conclusion Self-programming of the SP was safe and feasible in the studied sample of adults, since T- and C-levels were similar between the behavioral and RAF-adjusted maps. We consider it advisable to use the RAF for patients who have insertion of electrodes and at least one functioning; as well as those who do not have changes in anatomy, nor motor and cognitive conditions that prevent RAF usage.

Published: January 2025

The testing and modeling of semiconductor devices are the foundation of circuit design. The issue of high-power device testing urgently needs to be solved as the power level of the devices under test (DUTs) increases. This work proposes advanced measurement methods based on three aspects of “measuring capability, security, and stability” with a focus on the features of high output power, easy self-oscillation in mismatch tests, and safety risk in the measurement system of high-power transistors. In this paper, the wideband limiter and bias filter network are innovatively introduced to improve the stability and security of the measurement circuit. Meanwhile, the output signal of the DUT is suggested to be measured using a spectrum analyzer before the test to avoid damage to the circuit caused by the possible self-oscillation of the transistor. Moreover, an efficient test system of current parameters and S-parameters is developed, with coaxial fixtures offered to boost the test power capacity and cascade bridges adapted to satisfy the pulse operating conditions. Finally, based on the improved test methods, a gallium nitride high electron mobility transistor (GaN HEMT) with a gate width of 400 × 32 μm and a power density of roughly 10 W/mm was tested. A relatively complete I–V curve and a S-parameter curve were obtained, demonstrating the effectiveness and applicability of the improved methods.

Published: January 2025

Abstract
Livestock are vital to the health and economic stability of communities worldwide. However, infectious diseases threaten both animal and human health due to losses in livestock, decreased production, and transmission of zoonotic diseases. To manage and mitigate these risks, access to livestock vaccines is critical. This is often gendered, with societal and cultural norms influencing barriers to access. Through a scoping review of 49 publications, we describe the gendered dynamics of livestock vaccination in relation to farmers’ perceptions and knowledge about vaccines, access to vaccines and vaccination programs, and the ways in which roles and responsibilities in relation to cultural norms shape and limit women’s decision making power and empowerment to participate in such initiatives. We find that across communities, women face similar barriers to engaging in livestock vaccination programs, but that local context is critical to understanding and addressing these barriers. Within a broader context of the gendered dynamics of vaccination for both human and animal health, we highlight the need for vaccination programs that identify and address inequitable access to vaccines to support community and animal wellbeing as well as resilience to emerging health threats.

One Health impact statement
This article examines the gendered dynamics of livestock vaccination, emphasizing the need for a One Health approach to develop more equitable and effective vaccination strategies. By considering the intersection of human, animal, and environmental health, this review highlights structural inequities in vaccine distribution and access, the impact of gender roles on decision making and participation in vaccination programs, and the broader implications for animal health and community wellbeing. Drawing on insights from veterinary medicine, social sciences, and public health, we advocate for inclusive, gender-transformative programs that address the diverse needs of those involved in livestock care and community health.

Hippotherapy practice and safety patterns for adult clients in the United States
Authors: Hays Abby , Meera Benazir , Caitlin Peters B. , Erdman Ellen , Fields Beth 
Published: January 2025

Abstract

Objective:
Hippotherapy is a treatment strategy used by occupational therapy, speech-language, and physical therapy clinicians to influence client outcomes through the movement of a horse. While hippotherapy has been widely researched among pediatric populations with neuromuscular disorders, limited evidence exists regarding hippotherapy for adult populations. This study describes the practice patterns, safety patterns, and changes in these trends over time for clinicians who incorporate hippotherapy into treatment plans for adult populations in the United States (USA).
Design:
A survey was distributed via email listserv to American Hippotherapy Association, Inc. (AHA, Inc.) and Professional Association of Therapeutic Horsemanship, International (PATH, Intl.) members for 5 consecutive years. Clinicians were included in the study if they worked with adults (ages 18–64), practiced in the USA and were licensed physical therapists, physical therapy assistants, occupational therapists, occupational therapy assistants, speech-language pathologists, and speech-language pathologist assistants. Descriptive analyses were performed using Microsoft Excel.
Results:
The majority of the clinicians were physical therapists (2019 n = 8; 2020 n = 21; 2021 n = 26; 2022 n = 20; 2023 n = 20) working with clients who had cerebral palsy, autism spectrum disorder, or attention deficit disorder aged 18–26 and addressing neuromuscular client factors. Across the five years, <0.001–0.012 out of every one session included an emergency dismount, <0.001–0.003 out of every one session resulted in a safety occurrence that required on-site first aid, and <0.001–0.01 out of every one session resulted in an injury that required off-site first aid.
Conclusions:
The study findings describe consistent practice and safety patterns across time for adult clients with low numbers of adverse events. As the population ages, hippotherapy should be considered more often for adult clients. Clinicians can educate referring providers to advertise hippotherapy as adult-inclusive or age-friendly as appropriate. Researchers should examine the efficacy of hippotherapy for specific adult populations to guide the practice of clinicians incorporating hippotherapy into treatment plans for adult clients. Educators in accredited therapy programs and the AHA, Inc. should consider expanding their curriculum to include more adult-specific information for hippotherapy and draw attention to how and why the treatment strategy should be used with this population.
Simulated optical molasses cooling of trapped antihydrogen

Abstract
We theoretically and computationally investigate the cooling of antihydrogen,

, using optical molasses cooling. This updates the results in Donnan et al (2013 J. Phys. B: At. Mol. Opt. Phys.
46 025302) to the current capabilities of the ALPHA experiment. Through Monte Carlo simulation, we show that

H
¯

s do not give the standard cooling even in an ideal optical molasses because of their small mass and large transition frequency. For optical molasses cooling in the ALPHA trap, the photons are constrained to travel in one direction only. It is only through the phase space mixing in the trap that cooling in all directions can be achieved. We explore the nontrivial role that laser intensity plays in the cooling. We also investigate the possibility for simultaneously cooling atoms in either of the trapped ground states.

Published: January 2025

Abstract
This study introduces the solar-powered microbubble-enhanced plasma water-based nitrogen fixation (MEPWBNF) technology, a novel and environmentally friendly approach to nitrogen fixation that offers high efficiency. By employing Venturi tubes to produce a continuous flow of microbubbles, this technology significantly enhances the interaction between gaseous plasma nitrogen compounds and water, leading to improved solubility and reaction efficiency of nitrogen compounds in water. Comparative analyses reveal that MEPWBNF achieves a 33.7% reduction in energy consumption and a 52.8% increase in yield compared to traditional PWBNF methods without microbubble-enhanced method. Moreover, the resulting plasma-activated tap water can be directly utilized as a nutrient solution in hydroponic systems, effectively boosting lettuce growth. The adoption of MEPWBNF technology presents a promising strategy for reducing agricultural dependence on chemical fertilizers and advancing sustainable farming practices.
Insights into the molecular self-assembly of urea-functionalized acetylenes
Authors: K M Neethu , Nag Kritika , Jayamurugan Govindasamy 
Published: January 2025

Abstract
This study investigates simple acetylenes substituted with phenylurea as a constant H-bonding unit (Alk-R) and varied hydrophobic units (R = H, Phenyl (Ph), phenylacetylene (PA), Ph-NMe2) to understand self-assembly properties driven by synergistic non-covalent interactions. Our observations reveal hierarchical self-assembled fibrillar networks with luminescent needles, fibers, and flowers on nano- to micro-meter scales. Subtle changes in substituents led to significant differences: H, Ph, PA, and Ph-NMe2 produced needle-like crystals, dendritic nanofibers, microflakes, and no self-assembly, respectively. Alk-Ph-NMe2
likely did not self-assemble due to reduced hydrophobic interactions and steric hindrance. Interestingly, Alk-Ph exhibited a uniform spherulitic pattern and effectively gelled organic solvents and water. This luminescent gel demonstrated multifunctionality, including white light emission when doped with rhodamine-B dye and adsorption of organic cationic dyes (methylene blue and crystal violet) from water. This study offers valuable insights into balancing interactions to achieve desired hierarchical networks and understand material properties, guiding future molecular design.
