A speech-based convolutional neural network for human body posture classification
Authors: Abdulmohsin Husam Ali 
Published: October 2024

Abstract

Problem
In recent years, computing and sensing advances have helped to develop efficient human posture classification systems, which assist in creating health systems that contribute to enhancing elder’s and disable’s life quality in context-aware and ambient assistive living applications. Other applications of body posture classification include the simulation of human bodies into virtual characters, security applications such as kidnapping and the body position of the kidnapper or victim, which can provide useful information to the negotiator or the rescue team, and other sports applications.

Aim
This work aims to propose a body posture classification system based on speech using deep learning techniques.

Methods
All samples pass through the preprocessing phase. The Mel-frequency cepstral coefficient (MFCC) with 12 coefficients was used as features, and the best features were selected by the correlation-based feature selection method. Two supervised learning techniques called artificial hydrocarbon networks (AHN) and convolutional neural networks (CNN) were deployed to efficiently classify body postures and movements. This research aims to detect six human positions through speech, which include walking downstairs, sitting, walking upstairs, running, laying, and walking. The dataset used in this work was prepared by the authors, named the human activity speech dataset.

Results
The best performance gained was with the AHN classifier of 68.9% accuracy and 67.1% accuracy with the CNN.

Conclusion
It was concluded that the MFCC features are the most powerful features in body position classification, and the deep learning methods are powerful in classifying body positions.
Joint PAPR reduction with channel estimation for OFDM-based VLC systems
Authors: Ali Mansour Eliwi , Abdulkafi Ayad A. 
Published: October 2024

Abstract
This paper presents a new combination of channel estimation (CE) methods and peak-to-average power ratio (PAPR) reduction techniques for orthogonal frequency division multiplexing (OFDM)-based visible light communication (VLC) systems. We first propose iterative clipping and filtering to minimize the PAPR of optical OFDM signals. Then, we introduce a computationally efficient, high-performance channel estimation approach using block-type pilots with modified clipped signals. The proposed method integrates clipping with three distinct CE techniques, resulting in both significant PAPR reduction and enhanced bit error rate (BER) performance. Among the CE methods evaluated, the expectation-maximization (EM) technique provides better BER results compared to other approaches. Simulation results confirm that the combined use of clipping and advanced CE methods leads to notable improvements in PAPR reduction and BER performance for OFDM-based VLC systems.
Selecting optimal progestational agents either alone or in combination in common pediatric endocrine settings: challenges of unmet needs
Authors: Reich Jenna , Badrinath Murthy Deepa , Coble Chanelle , Shah Bina 
Published: October 2024

Abstract
Progesterone is a natural hormone, mainly produced by the corpus luteum, with the foremost endocrine function on the secretory glands of the endometrium. Since being isolated, both natural and synthetic forms have been produced and are utilized for several purposes, including regulating the menstrual cycle and preventing endometrial hyperplasia. Specifically, the use of progestational agents is essential in the treatment of many common endocrine conditions, including polycystic ovary syndrome, congenital adrenal hyperplasia Turner syndrome and functional hypothalamic amenorrhea. Although these agents are essential for disease management, literature that focuses on the benefits of specific progestins as well as the effects on glucocorticoid receptors (GR), mineralocorticoid receptors (MR), and androgenic receptors (AR) is limited. In this review, we provide a disease specific summary of the available literature and highlight where more information is needed.
Completely hereditarily atomic OMLS
Authors: Harding John , Kornell Andre 
Published: October 2024

Abstract
An irreducible complete atomic oml of infinite height cannot be algebraic and have the covering property. However, modest departure from these conditions allows infinite-height examples. We use an extension of Kalmbach’s construction to the setting of infinite chains to provide an example of an infinite-height, irreducible, algebraic oml with the 2-covering property, and Keller’s construction provides an example of an infinite-height, irreducible, complete oml that has the covering property and is completely hereditarily atomic. Completely hereditarily atomic omls generalize algebraic omls suitably to quantum predicate logic.
Global Mild Solutions For Hilfer Fractional Neutral Evolution Equation
Authors: Li Qien , Luo Danfeng 
Published: October 2024

Abstract
In this paper, we present the existence of global mild solutions for the Hilfer fractional neutral evolution equations (HFNEEs), regardless of whether the semigroups are compact or noncompact. We achieve our main results by utilizing the generalization Ascoli-Arzelà theorem, Krasnoselskii’s fixed point theorem, Laplace transform, and measures of noncompactness. To demonstrate the feasibility of our method, we provide an example.
The discrete fractional Karamata theorem and its applications
Authors: Řehák Pavel 
Published: October 2024

Abstract
We establish a fractional extension of the discrete Karamata integration theorem for two types of fractional sum operators. This result, along with other properties of regularly varying sequences and the tools such as comparison theorems and a fixed point theorem in FK-space, is then used to study asymptotic properties of solutions to a nonlinear fractional difference equation. We also establish and utilize a fractional extension of the Stolz–Cesáro theorem, i.e., of the discrete l’Hospital rule. Both, the discrete fractional Karamata theorem and the discrete fractional l’Hospital rule, are believed to find applications in a broader context within the discrete fractional calculus.

Abstract
Electric vehicles have become a standard means of transportation in the last 10 years. This paper aims to formalize design optimization problems for electric vehicle components. It presents a tool conceptual design technique with a hunger games search optimizer that incorporates dynamic adversary-based learning and diversity leader (referred to as HGS-DOL-DIL) to overcome the local optimum trap and low convergence rate limitations of the Hunger Games search algorithm to improve the convergence rate. The performance of the proposed algorithms is studied on six widely used engineering design problems, complex constraints, and discrete variables. For the HGS-DOL-DIL practical feasibility analysis, a case study of shape optimization of an electric car suspension arm from the industry is carried out. Overall, the inclusion of the OL strategy has proven its superiority in solving real-world problems, especially in solving real-world problems such as shape optimization of an electric vehicle automobile suspension arm, showing that the algorithm improves the search space improves the solution quality, and reflects its potential to find global optimum solutions in a well-balanced exploration and exploitation phase.

Authors: Lade Pravinkumar Dinkar , Singla Neelam 
Published: October 2024

Abstract

Background: Natural polysaccharide tara gum (TG) has been investigated for several biological uses. The current study involved the administration of imatinib, an anticancer model medication, via TG.

Methods: Imatinib-modified release tablets were developed using a direct compression method with different concentrations of TG and other excipients. Compressed tablets were evaluated for physicochemical properties.

Result: All formulations had an in vitro disintegration time ranging from 10–23 min. Among the formulations, F6 exhibited excellent extended-release behaviour with 72% release over 12 h. TG tablets were rich in phytoconstituents, including saponins, tannins, phenolics, flavonoids, carbohydrates, proteins, and amino acids.

Conclusion: TG has potential in the drug delivery application of anticancer medications as a rate-retarding polymer.
Improving access to sexual and reproductive health services among adolescent women in Zimbabwe
Authors: Mhlanga M , Mangombe A , Karumazondo J J , Yohannes T 
Published: October 2024

Background
Unplanned pregnancies increased among adolescents in Zimbabwe, resulting in unsafe abortions, sexual and gender-based violence, and forced marriages. Access to Sexual and Reproductive Health and Rights (SRHR) has been scanty among pregnant adolescents and adolescent mothers owing to negative social norms, stigma and discrimination. This project specifically targeted pregnant adolescents and adolescent mothers through a differentiated and targeted care approach to improve uptake and sexual and reproductive health outcomes.

Methods
Target-specific peer support groups for pregnant adolescents and adolescent mothers were established in Epworth district of Zimbabwe. The Champions of Change, a peer-based approach, was used to facilitate comprehensive sexuality education. Mentors were adolescent mothers trained on how to use a tailor-made manual to facilitate sessions. Two health centers, namely Epworth Clinic and Overspill Clinic, were purposively selected to participate in this study. A total of 60 participants were recruited into this study, 30 from each clinic. Knowledge and attitude were measured using a semi-structured questionnaire administered before and after the intervention. A scorecard was used to assess friendliness and quality of service provision. A Chi-square test of association was used to determine the significance of the change in outcomes.

Results
A significant improvement in knowledge of SRHR, attitudes, and healthcare-seeking behaviors was noted. There was a significant improvement in attitudes and friendliness in service provision. Access to services significantly increased with improvements in relationships and trust.

Conclusion
A targeted and differentiated care approach increases the uptake of services and health outcomes among adolescent women by addressing their unique needs and circumstances.

Lay summary
Adolescent pregnancy and motherhood have significantly risen in Zimbabwe with the advent of the COVID-19 pandemic. The condition of these adolescent women has been worsened by poor access to and utilization of sexual and reproductive health services by this unique group, resulting in poor sexual health outcomes. Pregnant adolescents and adolescent mothers are less likely to access sexual and reproductive health services due to heightened stigma and discrimination by peers, communities and service providers themselves. We adopted a peer-based approach to increase the agency of adolescent women and empower them through comprehensive sexuality education, engaging healthcare service providers, and improving parent-child communication. With our intervention, we noted a significant improvement in the proportion of pregnant adolescents and adolescent mothers accessing services and reporting improvement in relationships with parents and healthcare providers. We encourage health providers to consider providing targeted services to this group to improve uptake and health outcomes.

In brief
O-GlcNAc plays an important role in many age-related diseases. This study shows that O-GlcNAc participates in oocyte aging and that reducing O-GlcNAc levels in aging oocytes improves oocyte quality.

Abstract
With an increase in the mean age at parturition worldwide, female reproductive aging has become a key health problem. Advanced maternal age is reflected by decreased oocyte quality; however, the molecular mechanisms of oocyte aging are uncharacterized. O-linked N-acetylglucosamine (O-GlcNAc), a dynamic posttranslational modification, plays a critical role in the development of many age-related diseases; yet, it remains unclear whether and how O-GlcNAc participates in oocyte aging. Here, we found that global O-GlcNAc was elevated in normal biological aging mice oocytes (9 months), which were characterized by meiotic maturation failure and impaired mitochondrial function. Specifically, O-GlcNAc targeted the mitochondrial fission protein dynamic-related protein 1 to mediate mitochondrial distribution in the process of aging. Using the O-GlcNAcase (OGA) pharmacological inhibitor Thiamet-G and Oga knockdown (Oga-KD) to mimic the age-related high O-GlcNAc in young oocytes from 6–8 week-old mice mimicked the phenotype of oocyte aging. Moreover, reducing O-GlcNAc levels in aging oocytes restored spindle organization to improve oocyte quality. Our results demonstrate that O-GlcNAc is a key regulator of meiotic maturation that participates in the progression of oocyte aging.

OBJECTIVE
We sought to determine whether clonidine, a non-opioid α−2-adrenergic agonist, would effectively treat neonatal opioid withdrawal syndrome (NOWS).

METHODS
This was an intention-to-treat randomized clinical trial. Enrollment criteria included prenatal opioid exposure, age ≤7 days, gestational age ≥35 weeks, no other medical condition, and need for pharmacotherapy. Primary outcomes were length of treatment and neurobehavioral performance.

RESULTS
A total of 1107 patients were screened for enrollment (645 ineligible, 91 parents or staff unavailable, 216 declined, 155 consented). Of 155 infants, 120 required treatment and were randomized to receive oral clonidine (n = 60) at 1 µg/kg/dose or morphine (n = 60), 0.06 mg/kg/dose, every 3 hours. Infants with no improvement had their doses increased by 25% of the initial dose every 12 to 24 hours. Those without improvement by the fourth dose increase, received adjunct therapy. Length of treatment did not differ between morphine and clonidine, with median (95% confidence interval [CI]) days, respectively, of 15 (13–17) and 17 (15–19), P = .48. More clonidine-treated infants (45%) needed adjunct therapy versus 10% in the morphine group, adjusted odds ratio (95% CI) = 8.85 (2.87–27.31). After treatment completion, the NICU Network Neurobehavioral Scales summary scores did not differ between clonidine-treated and morphine-treated infants.

CONCLUSIONS
Length of pharmacologic treatment and final neurobehavioral performance were not significantly different between the clonidine- and morphine-treated groups. Clonidine appears to be an effective non-opioid medication to treat NOWS. Future studies are needed to determine the optimal clonidine dosage for a quicker response and obviation of adjunct therapy.

"Baby It’s You (Lucy Dacus Edit)" adopts principles from the fanvid to analyse aspects of characterisation and narrative development in John Sayles’ 1983 teen romance Baby It’s You. It explores the utility of using imported pop songs in scholarly videographic criticism and also tests certain conventions of the fanvid, namely the focus on the visual source, rather than the music chosen to accompany it, and the tendency to erase the screen text’s original music soundtrack.
