Potential Effects of Permanent Daylight Savings Time on Daylight Exposure and Risk during Commute Times across United States Cities in 2023–2024 Using a Biomathematical Model of Fatigue
Authors: Devine Jaime K. , Choynowski Jake , Hursh Steven R.
Published: August 2023

Background: Permanent Daylight Savings Time (DST) may improve road safety by providing more daylight in the evening but could merely shift risk to morning commutes or increase risk due to fatigue and circadian misalignment. Methods: To identify how potential daylight exposure and fatigue risk could differ between permanent DST versus permanent Standard Time (ST) or current time arrangements (CTA), generic work and school schedules in five United States cities were modeled in SAFTE-FAST biomathematical modeling software. Commute data were categorized by morning (0700–0900) and evening (1600–1800) rush hours. Results: Percent darkness was greater under DST compared with ST for the total waking day (t = 2.59, p = 0.03) and sleep periods (t = 2.46, p = 0.045). Waketimes occurred before sunrise 63 ± 41% percent of the time under DST compared with CTA (42 ± 37%) or ST (33 ± 38%; F(2,74) = 76.37; p < 0.001). Percent darkness was greater during morning (16 ± 31%) and lower during evening rush hour (0 ± 0%) in DST compared with either CTA (morning: 7 ± 23%; evening: 7 ± 14%) or ST (morning: 7 ± 23%; evening: 7 ± 15%). Discussion: Morning rush hour overlaps with students’ commutes and shift workers’ reverse commutes, which may increase traffic congestion and risk compared with evening rush hour. Switching to permanent DST may be more disruptive than either switching to ST or keeping CTA without noticeable benefit to fatigue or potential daylight exposure.

Authors: Attwa Mohamed W. , Abdelhameed Ali S. , Kadi Adnan A.
Published: August 2023

Ribociclib (Kisqali®) is a pharmacological agent that has great selectivity as a cyclin-dependent kinase 4/6 inhibitor. It has received regulatory approval for its application in the treatment of breast cancer. The objective of the current study was to develop a rapid, green, highly sensitive, validated, and specific LC–MS/MS approach for the quantification of RCB in human liver microsomes (HLMs) over the linear range of 1–3000 ng/mL (LLOQ: 0.98 ng/mL). The inter- and intraday precision and accuracy exhibited values ranging from −0.31% to 3.16% and −5.67% to 5.46% correspondingly. The eco-scale technique (AGREE program) was employed to examine the environmental impact of the existing LC–MS/MS technology. The in vitro half-life and intrinsic clearance of RCB were determined to be 23.58 min and 34.39 mL/min/kg, respectively, which indicated the intermediate extraction ratio of RCB. The in silico P450 software (version 6.6) was used to confirm and validate the practical results. The metabolism of RBC was previously studied by our research group, indicating that the piperazine ring and N-dimethyl group are responsible for the metabolic instability of RCB. Drug discovery studies can be conducted taking into account this concept, allowing the development of new drugs with an enhanced safety profile and good metabolic stability.

Published: August 2023

The different adsorption applications require the development of sorbents with predetermined properties. One of the ways for fine tuning the adsorption properties of the material is using a binary salt system as an active sorbing component. The aim of this work is to conduct a precision investigation of thermodynamic data on the sorption equilibrium of composite sorbents “(CaCl2 + CaBr2) confined to the silica gel pores” with water vapour. The isotherms and isosteres (at an uptake of N = 1.5 and 3.6 mole/mole) of water sorption on the composites were measured. It was shown that at a fixed temperature, the composites based on solid solutions of CaCl2 in CaBr2 form complexes with water at a pressure that is dependent on the CaCl2/CaBr2 molar ratio. The isosteric enthalpy and entropy of water sorption (ΔH = −48 ± 3 kJ/mol ΔS = −108 ± 2 J/(mol·K)) at N = 3.6 mole/mole were midway between the same parameters for composites on the base of the pure salts CaCl2 and CaBr2. The novelty of this work is in the design of sorbents optimized for air conditioning in hot climates and air drying cycles. It was shown that the use of the binary CaCl2 + CaBr2 system confined to the silica pores can be an effective tool for designing innovative materials with predetermined properties.

Published: August 2023

One of the frequently studied approaches in metric fixed-point theory is the generalization of the used metric space. Under this approach, in this study, we introduce a new extension of M-metric spaces, called controlled M-metric spaces, achieved by modifying the triangle inequality and keeping the symmetric condition of the space. The investigation focuses on exploring fundamental properties of this newly defined space, incorporating topological aspects. Several fixed-point theorems and fixed-circle results are established within these spaces complemented by illustrative examples to demonstrate the implications of our findings. Moreover, we present an application involving high-degree polynomial equations.
Numerical Analysis of Nonlinear Coupled Schrödinger–KdV System with Fractional Derivative
Authors: Alzahrani Abdulrahman B. M.
Published: August 2023

In this paper, we propose two efficient methods for solving the fractional-order Schrödinger–KdV system. The first method is the Laplace residual power series method (LRPSM), which involves expressing the solution as a power series and using residual correction to improve the accuracy of the solution. The second method is a new iterative method (NIM) that simplifies the problem and obtains a recursive formula for the solution. Both methods are applied to the Schrödinger–KdV system with fractional derivatives, which arises in many physical applications. Numerical experiments are performed to compare the accuracy and efficiency of the two methods. The results show that both methods can produce highly accurate solutions for the fractional Schrödinger–KdV system. However, the new iterative method is more efficient in terms of computational time and memory usage. Overall, our study demonstrates the effectiveness of the residual power series method and the new iterative method in solving fractional-order Schrödinger–KdV systems and provides a valuable tool for researchers and practitioners in applied mathematics and physics.

Published: August 2023

Thalassemia is one of the most prevalent genetic disorders worldwide and has previously been found to have an association with several physiological and organ complications. Several studies have found both its positive and inverse correlation with the glomerular filtration rate (GFR). Therefore, in this meta-analysis, we tried to assess the accurate correlation of β-thalassemia major (β-TM) with GFR. We searched in Google Scholar, PubMed, and ScienceDirect, and from the initial 96 articles, we finally included 12 studies. The quality and publication bias assessment confirmed that all the studies were of high to moderate quality with no publication bias. The main outcome of the mean difference (MD) was −6.94, 95%CI: −20.69, 6.80 (p < 0.00001), which indicated a negative correlation of the GFR with β-TM. The sensitivity analyses found one study to be a slight outlier, and reanalyzing the data excluding that study, an MD was achieved of −16.46, 95%CI: −26.81, −6.11 (p < 0.00001), which provides even stronger support for our main outcome. Our result determined that the GFR is generally higher in healthy people as compared to β-TM patients.
A First Analysis of the Ensemble of Local Maxima of Maximal Center Gauge
Authors: Dehghan Zeinab , Golubich Rudolf , Höllwieser Roman , Faber Manfried
Published: August 2023

Maximal center gauge (MCG) aims to detect some of the most important vacuum configurations, suggesting thick magnetic flux tubes quantized to non-trivial center elements of the gauge group being responsible for confinement. Due to the NP-hardness of a global maximization of the gauge functional only numeric procedures aiming for local maxima are possible. We observe a linear decrease in the string tension with increasing gauge functional value of the local maxima. This implies that the request to get as close as possible to the absolute maximum is unattainable. We compare global properties of the ensemble of local maxima with other methods to detect center vortices and with determinations of the string tension from full configurations. This comparison indicates that the information about the number and positions of center vortices is contained in the structure of the ensemble of local maxima. This may pave the way for a future more successful formulation of the gauge condition.
CSF Inflammation Markers Associated with Asymptomatic Viral Escape in Cerebrospinal Fluid of HIV-Positive Individuals on Antiretroviral Therapy
Authors: Guha Debjani , Misra Vikas , Yin Jun , Gabuzda Dana
Published: August 2023

HIV establishes a viral reservoir in the CNS despite viral suppression in the blood on antiretroviral therapy (ART). In a minority of people with HIV (PWH), HIV RNA is detectable in CSF when HIV RNA in plasma is undetectable or HIV RNA levels are higher in CSF compared with plasma, an event termed CSF viral escape that can occur with or without neurological symptoms. Asymptomatic CSF viral escape occurs in 3–20% of PWH on ART, yet associated biomarkers are unclear. To identify biomarkers associated with asymptomatic CSF viral escape, we performed a matched group study of PWH on ART with vs. without CSF viral escape (n = 10 and n = 60, respectively, matched for age, duration of HIV infection, nadir CD4 count, and ART regimen) and 50 HIV-negative controls. PWH were on 3 or more ART drugs for >1 year, and the group with no CSF viral escape was suppressed below 50 copies/mL in plasma and CSF. Biomarkers of inflammation (IFN-γ, IL-1β, IL-6, IL-8, IL-15, IP-10, MCP-1, VEGF), cell adhesion (ICAM-1, VCAM-1), CNS injury (NFL), and glial activation (GFAP, YKL-40) were measured in paired plasma and CSF using the Meso Scale Discovery platform. PWH with vs. without CSF viral escape had more individuals (40%) with a plasma viral load (VL) > 50 copies/mL, higher CSF VL (median 156 vs. 40 copies/mL; p < 0.0001), lower CD4 count (318 vs. 512; p = 0.045), and higher CSF WBC (median [IQR] 4 [0–22] vs. 2 [0–4] cells/µL; p = 0.15) but similar proportions with HIV-associated neurocognitive disorders (HAND) (50% vs. 47%). CSF viral escape was associated with increased IL-1β, IFN-γ, IP-10, ICAM-1, and VCAM-1 in CSF but not plasma; IP-10 had the strongest association (p = 0.0008). CSF VL and WBC correlated with IFN-γ, IP-10, ICAM-1, and VCAM-1 (p < 0.05). Although markers of CNS injury showed no significant association with asymptomatic CSF viral escape, CSF YKL-40 correlated positively with CSF IL-1β (p = 0.003), IFN-γ (p = 0.0008), IP-10 (p < 0.0001), and NFL (p = 0.06) and negatively with neurocognitive T scores (p = 0.02). These findings identify CSF inflammation and glial activation markers that may serve as surrogate measures of HIV persistence in the CNS for future studies on therapeutics targeting the CNS reservoir.

Published: August 2023

This study investigated changes in physical activity (PA) after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection while considering age, PA level, underlying medical conditions (UMCs), vaccination profiles/types, re-infections, disease severity, and treatment. Data were collected from 5829 respondents by using a validated web-based questionnaire. The findings showed that there was a significant overall decrease in PA (−16.2%), including in daily occupation (−11.9%), transportation (−13.5%), leisure-time (−16.4%), and sporting (−27.6%) activities. Age, PA level, UMCs, vaccination profiles/types, disease severity, and treatment played a role in determining PA in individuals’ post-acute SARS-CoV-2 infections. Re-infections did not impact the decline in PA. Unvaccinated individuals experienced a significant decline in PA (−13.7%). Younger (−22.4%) and older adults (−22.5%), those with higher PA levels (−20.6%), those with 2–5 UMCs (−23.1%), those who were vaccinated (−16.9%) or partially vaccinated (−19.1%), those with mRNA-type vaccines only (−17.1%), those with recurrent (−19.4%)-to-persistent (−54.2%) symptoms, and those that required hospital (−51.8%) or intensive care unit (−67.0%) admission during their infections had more pronounced declines in PA. These findings emphasize the complex relationship between post-acute SARS-CoV-2 infection and PA and highlight the need for targeted interventions, further research, and multidisciplinary care to promote PA resumption and mitigate long-term effects on global public health.

Background: Female sex workers (FSWs) are at a higher risk of contracting and transmitting HIV and other sexually transmitted infections (STIs). We aimed to explore the sexual behaviour, knowledge and attitudes towards STIs, barriers, support and intervention for STI screening. Methods: In this community-based, concurrent quantitative–qualitative, exploratory mixed-methods study, we administered 87 semi-structured quantitative and six in-depth interviews to purposively select FSWs in Gulu City, Uganda. The qualitative methodology was based on descriptive phenomenology. Results: The quantitative study included 87 FSWs, with a median age of 28 years. Overall, 87.4% (n = 76) participants reported condom use during their last sexual encounter. Eighty-three (95.4%) participants were aware of their HIV status, with 6% (n = 5) reporting being HIV-positive. Seventy-six (87.4%) participants reported contracting at least one STI during sex work. In addition, 66.7% (n = 58) of the participants reported being screened for STIs in the past three months, with vulvovaginal candidiasis (55.3%, n = 42) and syphilis (32.9%, n = 25) being the most common STIs. However, only 2.3% (n = 2) of the participants reported current STIs symptoms. In the qualitative study, the main themes encompassed sexual behaviour, including condom-use negotiation strategies and challenges, as well as screening facilitators and barriers. Condom-use negotiation tactics involved leveraging health-risk information, increased charges for unprotected sex, and outright refusal. Complex challenges included limited agency in promoting safe sex due to economic reliance, vulnerability to violence, and difficulties in controlling the sexual environment. Facilitators for regular screening included social influences, emotional relief, established testing habits, and accessible clinics, while barriers encompassed cost, stigma, doubts about test accuracy, and inconvenient clinic hours. Conclusions: FSWs face significant vulnerabilities in Gulu City, Uganda, regarding STIs. While encouraging trends such as high HIV awareness and condom usage were observed, persistent challenges in STI screening, negotiation of safe sex practices, and access to prevention and treatment remain evident. To address these concerns, targeted interventions should be developed to enhance STI screening accessibility, empower sex workers with effective negotiation skills, and provide comprehensive support for STI prevention and treatment, thereby contributing to improved overall sexual health and well-being among this marginalized population.

Published: August 2023

Aiming at the stability of a medium-voltage DC network based on a modular multilevel converter (MMC), this paper proposes an admittance stability criterion considering the influence of current-limiting inductors at the medium voltage side, which prevents the complex products and matrix calculations of traditional criteria. The DC admittance model DC transformers (DCTs) under different working modes are then established based on Thevenin/Norton equivalent circuit methods to analyze the stability of the DC system based on the proposed admittance stability criterion, which proves that the voltage resonance problem at the medium voltage side can be improved by adding active damping control strategies on DCTs also proves the effectiveness of the proposed stability criterion. The time-domain simulation and the hardware-in-loop simulation are then built in PLECS and RT Box to further verify the correctness of the system stability analysis and the effectiveness of the proposed admittance criterion, which provides a theoretical basis and technical reserve for the stable operation of the DC distribution power system.

Published: August 2023

Forest fires and field fires (agricultural areas, grasslands, etc.) have severe global implications, causing significant environmental and economic harm. Traditional fire detection methods often rely on human personnel, which can pose safety risks and reduce their efficiency in large-scale monitoring. There is an urgent need for real-time fire detection technology to address these challenges and minimize losses. In this research, we propose the utilization of artificial intelligence techniques, specifically Deep Learning with Convolutional Neural Networks (CNN), to tackle this issue. Our proposed system analyzes real-time images captured by IP cameras and stored on a cloud server. Its primary objective is to detect signs of fires and promptly notify users through a mobile application, ensuring timely awareness. We meticulously assembled a dataset to train our model by merging three existing datasets comprising both fire and non-fire images. Also, we incorporated images that could potentially be misinterpreted as fire, such as red trees, individuals wearing red clothing, and red flags. Furthermore, we supplemented the dataset with images of unaffected areas obtained from online sources. The final dataset consisted of 1,588 fire images and 909 non-fire images. During evaluations, our model achieved an accuracy of 93.07%. This enables effective detection, thus rapid intervention and damage reduction. It is a proactive and preventive solution to combat these devastating fires.
Total neoadjuvant therapy for rectal cancer: evidence and challenge
Authors: Lee Suk-Hwan
Published: August 2023

Recent advances in the management of rectal cancer have dramatically changed the clinical practice of colorectal surgeons because the main focus of rectal cancer treatment has changed from sphincter-saving to an organ-preserving strategies. Modifying the delivery of systemic chemotherapy to improve patients’ survival is another progress in colorectal cancer management, known as total neoadjuvant therapy (TNT). TNT is a new strategy used by colorectal surgeons to improve the quality of life and survival of patients after treatment. TNT poses limitations or obstacles, such as overtreatment issues in patients with stage I rectal cancer. However, considering the quality-of-life issues in patients with low-lying rectal cancer necessitating a permanent colostomy, the indication for TNT will be expanded. This review summarizes the recently conducted clinical trials and foresees future perspectives on TNT.

Partisipasi dan Agensi: Perempuan Muda selama Advokasi UU TPKS
Authors: Pratiwi Andi Misbahul
Published: August 2023

Since a decade ago, the women’s movement in Indonesia has consolidated its power to advocate for policies aimed at eliminating sexual violence through legislative advocacy and public campaigns. These efforts were a response to the increasing cases of sexual violence and the absence of a legal framework to address the issue. In the process of policy advocacy, young women have played a crucial role by participating in formal and informal political processes, although their participation has often been overlooked and unrecognized. This research examines the dynamics of young women’s activism in various forms at the national level in the advocacy process for Sexual Violence Criminal Law (UU Tindak Pidana Kekerasan Seksual/UU TPKS). This research aims to demonstrate the role and forms of activism among young women in advocating policies related to sexual violence. The study utilizes a qualitative methodology through in-depth interviews with eight young women activists involved in the advocacy, lobbying, and campaigning to pass the bill. The research finds that young women face various barriers and challenges, but simultaneously demonstrate their agency in the policy advocacy process.

This research discusses the advocacy strategy carried out by the Civil Society Network (JMS) by involving men to push for the ratification of the TPKS Law. By referring to the theory of the strategic capacity of gender equality policy advocates by Htun and Weldon, JMS has used organizational capacity through strategies of (1) framing demands; (2) building networks, and (3) lobbying policymakers. This study uses a qualitative method by conducting in-depth interviews to obtain primary data and collecting secondary data through a study of documents including regulations, news, and previously existing scientific papers. The findings from this study indicate that JMS involves men in advocacy strategies that are carried out by utilizing the privileges of men. For instance, the involvement of male religious leaders to counter the narrative of rejection of the TPKS Law which considers the TPKS Law to be inconsistent with the religious and moral values of the Indonesian people. Apart from that, JMS also involves male legislators who have a strategic position as Chairperson of the TPKS Law Working Committee to help lobby other members of the Indonesian Parliament.

El rápido crecimiento de la población humana ha provocado un drástico acondicionamiento de los ecosistemas en todo el mundo, dada la necesidad de satisfacer aspectos básicos de los urbanistas, lo que se traduce en una pérdida de la biodiversidad. Por esto, las comunidades que habitan en zonas urbanas se han convertido en objeto de interés por parte de los investigadores. Un ejemplo de esto es Calotropis procera (Aiton) Dryand. y las comunidades de hormigas en zonas urbanas de algunas regiones de Latinoamérica; la primera, una especie exótica ampliamente distribuida en zonas antropizadas de Suramérica, y las segundas, uno de los grupos de animales más diversos capaces de establecer estrechas asociaciones con las plantas. Tal es el caso de la asociación entre C. procera y un grupo de la comunidad de hormigas que habitan las zonas urbanas de la ciudad de Santa Marta, Colombia. Para determinar la estructura de la comunidad de hormigas asociadas a C. procera, se muestrearon 77 de estas plantas. En total, se registraron 21 especies de hormigas que de alguna manera interactuaban con C. procera. Esta interacción varía desde un aprovechamiento oportunista del recurso que ofrece la planta, hasta una relación más estrecha, como la nidificación de hormigas en las ramas huecas de la planta. La subfamilia con mayor número de especies fue Myrmicinae, mientras que la menos rica fue Dolichoderinae. Las especies más comunes fueron Camponotus lindigi Mayr, Brachymyrmex minutus Forel y Paratrechina longicornis (Latreille). Además, se registraron otras especies exóticas como Trichomyrmex destructor (Jerdon) y Tapinoma melanocephalum (Fabricius) en estrecha asociación con la planta.

The purpose of the study was to evaluate the effectiveness of the developed physical therapy program based on the dynamics of indicators characterizing the psychosomatic status of women with an endoprosthetic hip joint who underwent cesarean section. The control group consisted of 19 women without endoprostheses of the joints of the lower limbs. The main group consisted of 9 women 1 month after childbirth, which took place by caesarean section. The developed program of physical therapy lasted 1 month. Therapeutic exercises were applied; functional training, proprioceptive neuromuscular facilitation; massage of lower limbs, back. Movement limitations associated with an incompletely formed scar after cesarean section and the presence of an endoprosthesis were taken into account; accordingly, safe strategies for movements related to child care were created. Indicators of physical (hand and standing dynamometry, PWC170) and psychoemotional (Edinburgh Postnatal Depression Scale) status were determined. During the initial examination, deterioration of the psychosomatic status was found in women with an endoprosthetic hip joint – muscle weakness (according to dynamometry), low physical capacity (according to PWC170), psycho-emotional depression (according to the Edinburgh Postnatal Depression Scale). During re-examination, the condition of women characterized the dynamics of physiological recovery after abdominal delivery and the effectiveness of the physical therapy program in women of the main group. The improvement in static dynamometry and static strength index in the control group was 14.7% and 9.9%, respectively, in the main group – 27.2% and 21.7%. According to the results of PWC170, the physical performance of women in the control group improved by 13.4 %, and in the main group by 41.5%. In the control group, the improvement of psychoemotional status according to the Edinburgh Postnatal Depression Scale in the control group was 32.9 %, in the main group – 38.8 %. Based on the results of the study, it was concluded that it is advisable to prescribe physical therapy in the complex recovery of women with an endoprosthetic hip joint who underwent cesarean section, to reduce muscle weakness, increase work capacity, and improve psycho-emotional status.

To explore the application of traditional machine learning model in the intelligent management of pigs, in this paper, the influence of the PCA pre-treatment on pig face identification with KNN is studied. With testing method, individual identification test was carried out on 10 different pigs in two testing schemes, in which one adopted KNN alone and the other adopted PCA + KNN, for which the classifier parameter was taken as 3 and 5, respectively. In the optimized scheme, the operating efficiency got significantly increased, also the training time and testing time were reduced to 4.8% and 7% of the original value in the KNN alone scheme, though the accuracy got lowered to a certain extent. With all these factors taken into consideration, PCA pre-treatment is beneficial to individual pig identification with KNN. It can provide experimental support for mobile terminals and embedded application of KNN classifiers.

This study aims to analyze the debate-based SCL learning model from the perspective of Surah An-Nahl verse 125. This research is vital because learning methods are one of the factors that determine learning success. One method of teaching approach that has proven to be effective and efficient is student-centred Learning (SCL). Development of learning with the SCL model, learners can more quickly understand the material and a teacher can more easily internalize educational values. If we analyze the interpretation of Surah An-Nahl verse 125, several education methods will be found. The type of research used is qualitative research with a library research approach. To analyze the data, this study used secondary data derived from the book of tafsir, which explains surah An-Nahl verse 125 and several data references related to the research. The results showed that SCL was learning in the surah An-Nahl verse 125 content, namely debate-based learning. The passage "refute them with a good rebuttal" signifies a debate learning method. With the jidal/debate method, at least two intelligences are formed in the learners. That is intellectual intelligence with broad insights to develop arguments and emotional intelligence necessary to maintain debate ethics. However, the debate set in education is undoubtedly a debate with polite words, full of ethics and does not put forward emotions. From the analysis of Surah An-Nahl verse 125, a teacher can apply the debate-based SCL learning model to improve the quality of his teaching.

Photovoltaic Thermal (PV/T) collector is a device that can produce electrical energy and thermal energy simultaneously. However, the thermal energy increases the surface temperature of the PV and therefore it may reduce electrical efficiency. To overcome this problem, a finned thermal collector should be joined underneath the PV surface. The aim of this study is to simulate the thermal performance of a PV/T collector by using staggered fins with air as a working fluid. The parameters are varied from 25 to 50 mm in the fin geometry and from 12 to 48 g/s in air mass flow rate, respectively. Furthermore, the heat radiation used was 860 W⁄m2 and Computing Fluid Dynamic (CFD) method was implemented in this research. The results showed that the PV/T surface temperature decreased by 7.04 % for the fin height of 37.5 mm and 11.9 % for the fin height of 50 mm when compared to the fin height of 25 mm. Thus, a greater cooling of the PV/T surface occurs in the fin height of 50 mm due to an increase in the heat transfer area which might absorb more of the unused thermal energy in comparison with others.
