Published: June 2023

This research aims to describe the process of administering State Property at the Regional Coordinator of the Palu Religious High Court and to offer solutions in the perspective of basic accounting concepts. This research used a qualitative method with a post-positivism approach. The data collection process was carried out through observation, interviews, and documentation analysis using the triangulation model technique. The research results show that (1) that registration is application-based but there are still items that have not been coded according to the type of goods, recording is not supported by valid source documents and updating of data and information on State Property is not carried out regularly, (2) recording is not supported by documents valid sources, (3) State asset data and information are not updated regularly, (4) Inadequate inventory of State Property, (5) State Property reports have not been reported in a timely manner. An alternative to the concept of State Property Administration in the prospect of basic accounting concepts is entity theory, such as: (1) In bookkeeping, it is necessary to have an understanding of the recording of State property, both goods purchased through the State Budget, Grants and Inbound Transfers so that the difference in the presentation of State Property books is not occurs., (2) In the inventory it is necessary to update State property that is no longer in accordance with the needs or obsolete goods, (3) In reporting the need for detailed presentation of goods so that it is easy to present in the state property report (4) In the use of a system application in asset management, it is very necessary to have real policies related to the use of applications according to needs, so that the asset administration process can run effectively and efficiently, (5) Asset reports will be complete and reliable if there is a match between physical assets, ownership documents and records in the books inventory. Mechanism of State Property Administration g is good, then the process of transparency and accountability in the management of State Property will be realized.

Authors: Tiku David T. , Ngwabie Ngwa M. , Manga Veronica E. , Yengong Fabrice L. 
Published: June 2023

Background: Effective composting management practice through monitoring of composting governing parameters is very crucial in ensuring the safety and effectiveness of the composting process and hence the quality of the compost.
Aims: To assess the variability of the different physiochemical properties (pH, pile temperature, mass, VS, TS and TOC) during open-air dumping and windrow composting of raw pig manure and shavings amended pig manure with wood.
Study Design: Field and laboratory experiment.
Place and Duration of Study: Waste-to-resource project site and project laboratory of the Department of Environmental Science of the University of Buea, Cameroon between February and March 2022.
Methodology: Two sets of pig manure and wood shavings were mixed in mass ratios of 100%:0% and 90%:10% and placed in four different chambers. One set was dumped in an open-air situation while the other set was left to compost for 40 days. Piles were monitored after every next day for pH, temperature, mass loss, EC, MC, TOC, TS and VS analyses.
Results: The highest composting temperature (63.4℃) was experienced in the 90:10 % while the lowest (39.4℃) was experience in the 100%. All 100% treatments had an acidic starting pH (5.04 and 5.58) while 90:10% treatments had a more basic pH (6.76 and 6.82), there was a significant difference in EC between the open-air dumped and windrow compost piles (P = 0.000). Mass significantly reduced by 64% and 75% (100% and90:10% compost respectively), 51% and 56.5% (100% and 90:10%dumping respectively). Significant difference existed in MC (P = 0.010). Both VS and TC decrease across all treatments, the highest VS and TOC were observed in all 100:0% treatments.
Conclusion: Open-air dumping and composting of pig manure with woods shavings should be promoted since it enhances physiochemical properties, but more emphasis should be on composting than on open-air dumping.

Published: June 2023

Aims: This study was aimed at assessing the effects of social instability stress (SIS) and immobilization stress (IS) in postmenopausal (PM) conditions. Postmenopause is a physiological state often associated with mild neuronal disorders (NDs) such as anxiety and irritability. The aging of the worldwide population, coupled with multiple stressors, can lead to significant public health concerns, including severe NDs.
Place and Duration of Study: Tests and analyses were carried out within the confines of the Laboratory of Animal Physiology of the University of Yaoundé I (Cameroon) for 3 months.
Study Design: To induce PM syndrome, an 84-day ovariectomized Wistar rat model was used.
Methodology: Random sampling of 4 groups of 6 rats, each aged between 8 and 10 weeks, was used. SIS and IS were induced during PM installation. Behavioral status, biochemical, and histopathological analyses were carried out.
Results: SIS combined with IS exacerbates NDs induced by low estrogen levels. Furthermore, ovariectomized stressed rats are more depressed and anxious than the control. They presented severe hippocampal inflammation, oxidative stress, and memory impairment owing to low levels of ACh and reduced neuronal expression in the hippocampus. Overall, PM status makes NDs linked to stress worse in rats.
Conclusion: Stress promotes oxidative stress, neuroinflammation, and neuronal death, leading to greater affective and cognition disorders when estrogen levels are low. Thus, there is a need to focus on the management of stress during menopausal life.

ImportanceCOVID-19 vaccine hesitancy among Black women is a critical public health concern, potentially exacerbating existing health disparities and impacting community-wide vaccination efforts.ObjectiveTo explore the factors associated with COVID-19 vaccine hesitancy among Black women in the US and identify the specific concerns and experiences shaping hesitant attitudes toward vaccination.Design, Setting, and ParticipantsQualitative study using in-depth, semistructured interviews conducted virtually between June and November 2021. Thematic analysis was used to identify key themes from the interview data. Participants were recruited through social media platforms and word-of-mouth referrals from various regions of the US. Interviews were conducted remotely via Zoom. Data were analyzed from June to October 2023.Main Outcomes and MeasuresIdentification of key themes associated with COVID-19 vaccine hesitancy, identified through thematic analysis of interview data.ResultsFifty-four Black women aged 21 to 66 years participated in the study. Most participants (41 [75.9%]) resided in the South. The sample was predominantly well-educated, with 41 (75.9%) holding a bachelor’s degree or higher. Income levels varied, with 16 (29.6%) earning between $40 000 and $59 999 annually. Regarding family structure, 32 participants (59.3%) reported having no children, while 22 (40.7%) had 1 or more children. Three primary themes emerged as being associated with vaccine hesitancy: (1) mistrust in health care and government, rooted in past medical exploitation; (2) concerns over vaccine safety and long-term effects, particularly regarding reproductive health; and (3) ineffective and coercive vaccine communication and promotion. Participants expressed deep-rooted skepticism about being treated as “expendable” in medical research, fears about the rapid vaccine development process, and frustration with coercive vaccine advertisements. Many women desired more comprehensive education about vaccine mechanisms and criticized the use of coercive financial incentives and celebrity endorsements in vaccine promotion.Conclusions and RelevanceAddressing COVID-19 vaccine hesitancy among Black women requires a multifaceted approach that acknowledges historical traumas, provides clear and transparent safety information, and avoids coercive vaccine promotion strategies. These findings emphasize the need for health care practitioners and public health officials to prioritize trust-building, engage community leaders, and tailor interventions to address the unique concerns of Black women to improve vaccine confidence and uptake.

ImportanceCochlear implants enable improvements in speech perception, but music perception outcomes remain variable. Image-guided cochlear implant programming has emerged as a potential programming strategy for increasing the quality of spectral information delivered through the cochlear implant to improve outcomes.ObjectivesTo perform 2 experiments, the first of which modeled the variance in music perception scores as a function of electrode positioning factors, and the second of which evaluated image-guided cochlear implant programming as a strategy to improve music perception with a cochlear implant.Design, Setting, and ParticipantsThis single-center, prospective study recruited 50 adult patients with at least 6 months of cochlear implant listening experience and normal cochlear anatomy to participate in experiment 1 from 2013 to 2023. Data analysis was conducted from January to February 2024. Thirty-four of the 50 patients from experiment 1 also completed experiment 2.InterventionsCochlear implant programming using a computed tomography–guided electrode selection strategy.Main Outcomes and MeasuresUniversity of Washington Clinical Assessment of Music score, including subtests of pitch discrimination thresholds, isochronous familiar melody recognition, and timbre recognition.ResultsOf 50 participants, 20 (40%) were female, and the mean (SD) age was 57.7 (16.4) years. Experiment 1 suggested that better music perception abilities in the 50 participants were associated with patients who were younger and had a postlingual onset of deafness, as well as electrode arrays with a full scala tympani insertion, higher modiolar distance, and shallower insertion depth. Experiment 2 suggested improvements in melody recognition in the 34 participants using the image-guided cochlear implant programming strategy. Patients with apical electrodes that were deactivated were more likely to demonstrate an improvement in their pitch perception thresholds with the image-guided strategy, likely due to the low-frequency stimuli used in the University of Washington Clinical Assessment of Music.Conclusions and RelevanceThis study identified patient and device factors that were associated with music perception outcomes with a cochlear implant. These findings suggest that a personalized, image-guided approach to programming may improve music perception abilities for patients with cochlear implants.

Published: January 2025

ABSTRACTThe aim of this paper is to study the predefined‐time synchronization of coupled competitive neural networks (NNs) as well as the impacts of time‐varying delays on the predefined‐time synchronization performance. First, the models for drive and response systems of coupled competitive NNs with and without coupling delays are established for the first time in this work. After that, the predefined‐time synchronization of the proposed network models is investigated, and some new predefined‐time synchronization conditions for the considered drive and response systems are derived by designing novel bilayer controllers and using some inequality techniques. It is worth mentioning that the desired convergence time can be adjusted by presetting the parameters in the controllers in advance. Moreover, the synchronization is achieved in the predefined time regardless of the initial value of the coupled competitive NNs. At last, the proposed synchronization conditions are validated through two examples.

Published: January 2025

AbstractAntiferromagnetic (AF) skyrmions are topological spin structures with fully compensated, net‐zero magnetization. Compared to their ferromagnetic (FM) skyrmion counterparts, their reduced stray field and enhanced electrical response can enable linear, high‐throughput current‐driven motion. However, their bubble‐like character in conventional bilayer AFs limits their stability to fluctuations, leading to deformation and annihilation. This work presents the engineering of a composite AF chiral multilayer, wherein the interplay of AF and FM interlayer couplings generates compensated skyrmions with compact structures. High‐resolution magnetic imaging and micromagnetic simulations show that the internal exchange field stabilizes AF skyrmions at zero external field with characteristics comparable to FM counterparts at 100 mT. Quantitative analyses establish their decoupling above the exchange field, yielding independent, spatially segregated textures in constituent chiral layers. This work provides a foundation to develop AF spin‐textures with enhanced immunity, compatible with efficient readout and manipulation, with relevance to unconventional computing.

Published: January 2025

AbstractFor size‐sensitive catalytic reaction systems, precise control of geometric size of heterogeneous transition metal catalysts, especially for non‐noble metals, is in desperate need and also a great challenge. Here, highly dispersed Ni nanoparticles (NPs) anchored within mesoporous silica (MS) is fabricated through a hybrid strategy of amino‐modification and vacuum‐impregnation. The Ni NPs in Ni/MS catalyst can be precisely regulated from 2.2 to 12.6 nm, causing a variation in the proportion of low and high coordination sites of Ni atoms. The Ni/MS catalysts show a volcanic trend between 2‐methoxy‐4‐methylphenol (MMP) yield and Ni geometry size in hydrodeoxygenation (HDO) of bio‐derived vanillin, and the Ni/MS‐4.8 catalyst with middle size (4.8 nm) shows optimal HDO performance with the highest MMP productivity of 19.5 gMMP gNi−1 h−1. DFT calculation demonstrates that the medium‐sized Ni/MS‐4.8 catalyst possesses abundant low/high coordinated Ni atoms, wherein the low coordinated Ni atoms facilitate the adsorption of H2 and vanillin, and the high coordinated Ni atoms promote the dissociation of H2 and activating of C═O and C─O bonds, thus displays superior performance in HDO reaction. This work paves a way in precise control of geometric size of heterogeneous catalysts applicating in size‐sensitive catalysis.

Published: January 2025

AbstractImmobilization of fragile enzymes in a suitable support material provides new opportunities to improve the performance of immunosensor, but construction remains challenging due to the dimensional limitation or denaturation during the process. Herein, an enzyme‐engineered assembly strategy that enables the in situ fusion of enzymes into the framework structure during the crystal formation process via the covalent‐polymerization‐permeation mechanism is demonstrated, utilizing the dynamic covalent chemistry property of covalent organic frameworks (COFs‐PB). By finely regulating the assembling order of building blocks, enzyme‐COFs composite with the spatial distribution structure of the enzyme (such as uniform, sub‐surfaces, or interface) can be evolved, featuring controllable activity and structural stability. Impressively, the apparent enzymatic kinetics of the enzyme can be well maintained after encapsulation in COFs‐PB, and enzyme@COFs‐PB composite has shown outstanding stability in strongly acidic environments. Benefiting from structural integration, a robust enzyme@COFs‐PB‐based immunosensor is built for the sensitive detection of isocarbophos pesticide, which performed a 56‐fold enhancement in sensitivity compared with that of the standard immunosensor. This study gives valuable insight into a comprehensive understanding of the interfacial interactions between enzymes and COFs in designing ideal biocatalytic nanosystems, providing important guidance for the development of advanced immunosensors in on‐site application.

AbstractGas diffusion electrodes hold significant potential in the field of CO2 reduction, yet facing a major challenge of flooding within the catalyst layer. Common modification methods, such as coating with hydrophobic organics or incorporating them to catalyst inks, tend to seal gas transport pores or impact electrical conductivity, limiting the enhancement of current density during electrocatalytic CO2 reduction reaction. This paper describes the design and realization of a conformal hydrophobic modification, which is enabled by initiated chemical vapor deposition (iCVD) that conformally deposits a controllable thickness of hydrophobic poly(1H, 1H, 2H, 2H‐perfluorodecyl acrylate, PFDA) (PPFDA) inside aggregated Ag nanoparticles with interstitial porosity, loaded on carbon paper. Characterization and electrocatalytic experiments reveal that the hydrophobic modification of iCVD not only prevents the sealing of gas‐transporting pores but also maintains electrode conductivity. This improvement facilitates enhanced mass transfer of gaseous CO2 during electrochemical CO2 reduction reaction, leading to an increase in current density. The iCVD conformally modified electrodes exhibited excellent electrocatalytic performance in both a flow cell and a membrane electrode assembly (MEA) electrolyzers. A notable CO Faradaic efficiency of 93.5% is achieved at a current density of 300 mA cm−2 in a 4 cm2 MEA electrolyzer, accompanied by an exceptional stability improvement.

AbstractHigh‐performance soft–hard interfaces are inherently difficult to fabricate due to the dissimilar mechanical properties of both materials, especially when connecting extremely soft biomaterials, such as hydrogels, to much harder biomaterials, such as rigid polymers. Nevertheless, there is significant clinical demand for synthetic soft–hard interfaces. Here, soft–hard interface geometries are proposed, designed with the aid of computational analyses and fabricated as 3D‐printed hydrogel‐to‐polylactide (PLA) structures. Two primary interlocking geometries (i.e., anti‐trapezoidal (AT) and double‐hook (DH)) are used to study the envelope of 2.5D geometric interlocking designs, fabricated through hybrid 3D printing, combining pneumatic extrusion with fused deposition modeling. Finite‐element analysis, uniaxial tensile tests, and digital image correlation (DIC) are used to characterize the geometries and identify parameters that significantly influence their mechanical performance. These findings reveal significant differences between geometric designs, where DH geometries performed significantly better than AT geometries, exhibiting a 190% increase in the maximum force, Fmax, and a 340% increase in the fracture toughness, W. Compared to the control groups (i.e., flat, inset, and 90° interfaces), Fmax and W values increased by 500%–990% and 350%–1200%, respectively. The findings of this study can serve as a guideline for the design and fabrication of efficient soft–hard interfaces with performances close to predicted values.

Published: January 2025

AbstractAlzheimer’s disease (AD) is a complex disease that is often accompanied by a range of comorbidities, such as cardiovascular disease, diabetes, and depression. These comorbidities can impact the progression of AD and can complicate treatment strategies. Targeting comorbidities in Alzheimer’s disease and developing combination therapies are emerging areas of research.The following topics will be addressed:• Review of main AD comorbidities• Contributors to the pathophysiology and progression of Alzheimer’s disease (i. e neuroinflammation, vascular damage, etc) are common ground in some of the AD comorbidities• Cognitive function can be impacted by the associated comorbidities (i.e depression and anxiety) and concomitant treatments (i.e sedatives)• Developing combination therapies that target multiple aspects of Alzheimer’s disease and its comorbidities could prove more effective than targeting a single aspect of the diseaseBy also targeting comorbidities in Alzheimer’s disease and developing combination therapies, researchers and healthcare providers can find more effective ways to address the complex nature of Alzheimer´s. These strategies may ultimately lead to improve outcomes for patients with Alzheimer’s disease and its comorbidities.
