Authors: Shan Youcheng , Su Yuening , Lin Jiahui , Shan Tingyu
Published: January 2024

The MQTT IoT connection technology is widely used, becoming the primary means for IoT devices to communicate with servers amid the vigorous development of IoT technology. On the OneNET cloud platform, MQTT protocol connection and data communication, message sending, and subscription are established, one-to-many message transmission is solved, and the reverse control from server to device is realized in big data environment. This technology can provide fast and secure messaging services for remote devices with a small code capacity and limited bandwidth. Experiments indicated that the communication mode has low cost, small bandwidth, and slight delay, which meets the requirements of device data acquisition and control in a large area and has broad application prospects and reference significance in the field of mobile applications.

Published: January 2024

Despite being one of the most abundant elements in soil, phosphorus (P) often becomes a limiting macronutrient for plants due to its low bioavailability, primarily locked away in insoluble organic and inorganic forms. Phosphate solubilizing and mineralizing bacteria, also called phosphobacteria, isolated from P-deficient soils have emerged as a promising biofertilizer alternative, capable of converting these recalcitrant P forms into plant-available phosphates. Three such phosphobacteria strains - Serratia sp. RJAL6, Klebsiella sp. RCJ4, and Enterobacter sp. 198 - previously demonstrated their particular strength as plant growth promoters for wheat, ryegrass, or avocado under abiotic stresses and P deficiency. Comparative genomic analysis of their draft genomes revealed several genes encoding key functionalities, including alkaline phosphatases, isonitrile secondary metabolites, enterobactin biosynthesis and genes associated to the production of indole-3-acetic acid (IAA) and gluconic acid. Moreover, overall genome relatedness indexes (OGRIs) revealed substantial divergence between Serratia sp. RJAL6 and its closest phylogenetic neighbors, Serratia nematodiphila and Serratia bockelmanii. This compelling evidence suggests that RJAL6 merits classification as a novel species. This in silico genomic analysis provides vital insights into the plant growth-promoting capabilities and provenance of these promising PSRB strains. Notably, it paves the way for further characterization and potential application of the newly identified Serratia species as a powerful bioinoculant in future agricultural settings.

Pyridoxine is a versatile molecule that forms part of the family of B vitamins. It is used to treat and prevent vitamin B6 deficiency and certain type of metabolic disorders. Besides, pyridoxine molecule has been investigated as a suitable ligand toward metal ions. Nevertheless, the study of the magnetic properties of metal complexes containing lanthanide(III) ions and this biomolecule has been unexplored. We have synthesized and characterized a novel pyridoxine-based GdIII complex of formula [Gd(III)(pyr)2(H2O)4]Cl3 • 2 H2O (1) [pyr = pyridoxine]. 1 crystallizes in the triclinic system with space group Pī. In its crystal packing, the cationic [Gd(pyr)2(H2O)4]3+ entities are linked each other through H-bonding interactions involving non-coordinating water molecules and chloride anions. In addition, Hirshfeld surfaces of 1 were calculated to further investigate their intermolecular interactions in the crystal lattice. The study of the magnetic properties of 1 through ac magnetic susceptibility measurements reveals the occurrence of slow relaxation of magnetization in this mononuclear Gd(III) complex, this fact indicating an unusual single-ion magnet (SIM) behavior. We have also studied the relaxometric properties of 1, as a potential contrast agent for high-field MR imaging, from solutions of 1 prepared in physiological serum (0.0 - 3.2 mM range) and measured at 3 T on a clinical MR scanner. The relaxivity values obtained for 1 are larger than those of some commercial MR imaging contrast agents based on mononuclear Gd(III) systems

Published: January 2024

Heat-stressed lactating dairy cattle exhibit unique metabolic symptoms; many of which are undoubtedly involved in heat-induced subfertility. Because of its known systemic effects, we hypothesized that γ-aminobutyric acid (GABA) participates in the regulation of insulin and progesterone during heat stress. Multiparous lactating Holstein cows (n=6) were studied during four experimental periods: 1) thermoneutral (TN; d 1-5), 2) TN + hyperinsulinemic-hypoglycemic clamp (d 6-10), 3) heat stress (HS; d 16-20), and 4) HS + euglycemic clamp (d 21-25). Blood samples were collected once daily via coccygeal venipuncture into heparinized evacuated tubes. Analysis of GABA concentrations from all four treatment periods yielded no differences. In direct comparison to TN concentrations, plasma GABA tended to be decreased during HS (16.57±2.64 vs 13.87±2.28 ng/ml, respectively, P = 0.06). Both milk production and plasma insulin were moderately correlated with plasma GABA (r=0.35, P<0.01; r = -0.32, P<0.01). Plasma progesterone was correlated with plasma GABA concentrations during TN but not HS. These results are the first to indicate that peripheral GABA could be involved in regulating aspects of production and reproduction during heat stress. More research is needed to determine its precise role(s).
The Effect of Community Police on Community Development in Addis Ababa City Administration
Authors: alehegn derese
Published: January 2024

The study aimed to evaluate the impact of community policing on maintaining community safety and security by measuring the rate of crime prevention. Specifically, it sought to find out how the city administration of Addis Ababa demonstrated and promoted understanding of the community policing effort, information sharing, and community members' opinions regarding community policing in relation to local security procedures. Law enforcement initiatives to improve quality of life and reduce crime are also included. In order to be successful, community policing requires concrete actions and projects, and given the pervasive mistrust in today's public, both police departments and individual officers must take the lead. The findings demonstrated the influence of community policing, information sharing, and their results on local security practices as well as community policing among community members. According to one suggestion, the police should make sure that they interact positively with the community and that people are aware of their involvement in community policing. This way, people will be happy to provide the police with information that could help prevent crime. The public should be encouraged to maintain good connections with the police, as they can enhance community policing. Because it were obvious that doing so will improve society's peace and security, this study showed the need for additional efforts to further cement relationships of collaboration between the police and the community.

The fate of critically sick patients with infections in intensive care units (ICUs) is significantly influenced by antimicrobial resistance, which has become a serious concern in developing nations. This observational study was conducted at the IBN Sina Specialised Hospital in Dhaka, Bangladesh, over a 12-month period from January 2021 to December 2021, in order to track the pattern of antibiotic resistance among the patients admitted to the intensive care unit (ICU). Aspiration pneumonia (29%) and diabetes mellitus (24%), among 200 patients, were the most common main diagnoses. 65 samples (or 26%) of the 250 samples had 85 bacteria identified from them. Urine (14.12%) and tracheal aspirate (64.71%) were the most frequently found sites of infection. In the sample from the tracheal aspirate, Pseudomonas spp. (30.59%), Escherichia coli (24.71%), Acinetobacter spp. (20%), and Klebsiella spp. (14.12) were the most frequently isolated microorganisms. The following antibiotics were shown to have the highest overall patterns of resistance: levofloxacin (68.24), amikacin (64.71), meropenem (49.41), ceftazidime (75.29), ciprofloxacin (78.82), and gentamicin (82.35). The most effective antibiotic against Klebsiella species was meropenem (64.61%), while Acinetobacter species were mostly susceptible to cotrimoxazole (64.67%) and piperacillin + tazobactam (60.50%). Most susceptible to netilmicin (70.48%) and meropenem (49.32%) were Escherichia coli, while Pseudomonas spp. were mostly responsive to colistin (55.14%) and netilmicin (52.25%). Antibiotic resistance is common among intensive care unit (ICU) patients, and most isolated microbes have resistance to traditional medicines.
A Quantitative Analysis of the Need for High Conversion Efficiency PV Technologies in Carbon Mitigation Strategy
Authors: Hughes Kenneth , Phillips Chris C.
Published: January 2024

We consider the restrictions on photovoltaic (PV) capacity that are caused by limitations on where panels can be sited, and find quantitative evidence for the need for high efficiencies. We define 15% of the UK’s energy consumption as a “significant” contribution and, with London as an exemplar, we perform an idealised calculation that makes the most optimistic possible assumptions about the capabilities of future PV technologies, and use published surveys of energy usage, dwelling type and insolation. We find that covering every UK domestic roof with the highest power-conversion efficiency (PCE) solar panels currently commercially available, could produce up to 9% of the UK's energy. A 15% contribution would require PV technologies with >37% PCE, more than the theoretical Shockley-Queisser limit. Replacing the idealising assumptions with more realistic estimates increases this by 2-3 times. Alternatively, a solar farm using the currently available PCEs would require a politically challenging ~1200km2 of new land, roughly the area of Greater London, for this 15% contribution. We conclude that PCEs must be driven higher even than the Shockley-Queisser limit for PV to play a significant part in carbon mitigation.

Light is an electromagnetic radiation that has visible and invisible wavelength spectrum. The visible light can only be detected by the eyes through the optic pathways. With the presence of scalp, cranium and meninges, the brain is seen as being protected from direct exposure to light. For that reason, the brain can be viewed as a black body lying inside a black box. In physics, a black body tends to be in thermal equilibrium with its environment and can tightly regulate its temperature via thermodynamics principles. Therefore, a healthy brain inside a black box should not get exposed to light. On the contrary, photobiomodulation, a form of light therapy to the brain has been shown to have beneficial effects for some neurological conditions. The proposed underlying mechanisms are multiple. Herein we present our intraoperative findings of rapid electrocorticographic brainwave changes when the brain was shone directly with different wavelengths of light during awake brain surgery. Our findings provide literature proof on light’s ability to influence human brain energy and function. Our proposed mechanism for these rapid changes is the presence of plasma-like energy inside the brain which causes fast brain activities that are akin to lightning strikes.

Published: January 2024

Insurance serves as a mechanism to effectively manage and transfer revenue-related risks. We conducted a study to explore the potential financial advantages of index insurance, which protects agricultural producers, specifically sugarcane, against excessive rainfall. Creation of the index involved utilizing generalized additive regression models, allowing for consideration of non-linear effects and quantile generalized additive regression to evaluate relationships with lower quantiles, such as low yield events. To quantify the financial benefits for farmers, should they opt for excessive rainfall index insurance, we employed efficiency analysis based on metrics such as Conditional Tail Expectation, Certainty Equivalence of Revenue, and Mean Root Square Loss. The results of the regression model demonstrate its accuracy in predicting sugar cane yields, with a split testing R2 of 0.691. Additionally, our study suggests that this type of insurance could also apply to sugarcane farmers and other crop producers in regions where extreme rainfall threatens the financial sustainability of agricultural production.

Published: January 2024

This study investigated the impact of chitosan (CH, 1%) and aloe vera gel (AL, 30%) edible coatings on the preservation of blue honeysuckle quality during a 28-day storage at -1°C. Coating with CH, AL, and CH+AL led to notable enhancements in several key attributes. These included increased firmness, total soluble solids, acidity, pH, and antioxidant capacity (measured through DPPH, ABTS, and FRAP assays), as well as the preservation of primary (ascorbic acid) and secondary metabolites (TPC, TAC, and TFC). These coatings also resulted in reduced weight loss, respiration rate, color, abscisic acid, ethylene production, and malondialdehyde content. Notably, the CH+AL treatment excelled in preserving secondary metabolites and elevating FRAP-reducing power, demonstrating a remarkable 1.43-fold increase compared to the control after 28 days. Overall, CH+AL exhibited superior effects compared to CH or AL treatment alone, offering a promising strategy for extending shelf life and preserving quality of blue honeysuckle during storage.

Published: January 2024

Obesity is invariably accompanied by autonomic dysfunction, although data in pediatric populations are conflicting. We conducted a systematic review and meta-analysis of 12 studies (totaling 1102 participants) comparing obese and normal-weight subjects (5-18 years of age), defined as body mass index >95th or <85th percentile, respectively. Using a random-effects model, we report the standardized mean differences (SMD) of sympathetic and vagal indices, calculated by heart rate variability. Autonomic dysfunction was present in the obese group, based on the average SMD in the standard deviation of sinus intervals (at -0.5340), and on the ratio of low (LF) to high (HF) frequency spectra (at 0.5735). There was no difference in sympathetic activity, but the heterogeneity among the relevant studies weakens this result. SMD in HF (at 0.5876), in the root mean square of successive differences between intervals (at -0.6333), and in the number of times successive intervals exceeded 50ms divided by the total number of intervals (at -0.5867) indicated lower vagal activity in the obesity group. Thus, autonomic dysfunction is present in obese children and adolescents, attributed to lower vagal activity. Further studies on autonomic function are needed in various pediatric cohorts, placing emphasis on sympathetic activity.
Weighted Similarity-Confidence Laplacian Synthesis for High-Resolution Art Painting Completion
Authors: Sari Irawati Nurmala , Du Weiwei
Published: January 2024

Artistic image completion is fundamental for the preservation and restoration of invaluable art paintings and it has experienced significant progress through the implementation of deep learning methodologies. Despite these advancements, challenges persist, even with sophisticated approaches like Generative Adversarial Networks (GANs), particularly in achieving optimal results for high-resolution paintings. Small-scale texture synthesis and the inference of missing information from distant contexts present persistent issues, leading to distortions in lines and unnatural colors, especially in art paintings with complicated structures and textures. Concurrently, patch-based image synthesis has evolved by incorporating global optimization on the image pyramid to enhance structural coherence and details. However, methods relying on gradient-based synthesis encounter obstacles related to directionality, inconsistency, and the heavy computational burdens associated with solving the Poisson equation in non-integrable gradient fields. This paper introduces a groundbreaking approach, integrating Weighted Similarity-Confidence Laplacian Synthesis, to comprehensively address these challenges and advance the field of artistic image completion. This proposal addresses challenges not only in high-resolution artistic image completion but also makes a significant contribution to the broader field of patch-based synthesis by utilizing the Laplacian pyramid for enhanced edge-aware correspondence search. Experimental result confirms the effectiveness of our approach, offering promising outcomes for the preservation and restoration of art paintings with complicated details and irregular missing regions.

Published: January 2024

Background and objectives: The incidence of hip fractures in advanced age is increasing due to the aging society. In trochanteric region fractures of the femur, patient positioning can be performed various ways. The aim of this study is to clinically and radiologically compare the use of the supine hemilithotomy position, the lateral decubitus position, and the traction table when performing PFN surgery for femoral intertrochanteric fractures in the geriatric age group.Materials and Methods: A total of 170 older patients with femoral intertrochanteric fractures were included in this cross-sectional study. The patients were divided into three groups the supine hemilithotomy group, lateral decubitus group and fracture table. For the postoperative period, complications, length of stay in the intensive care unit, and length of stay in hospital were examined, while in postoperative radiographs, tip-apex distance (TAD), collodiaphyseal angle (CDA), and Cleveland-Bosworth quadrants were examined to evaluate the placement of the lag screw in the femoral head. Quality of fracture reduction was evaluated according to the modified Baumgaertner criteria.Results: The mean age of the patients was 77.77±8.8; 57.6% of patients were female. According to the modified Baumgaertner criteria, it was determined that patients with ‘poor’ reduction quality had an approximately ten times higher risk of cut-out than those with ‘good’ reduction quality. (OR = 10.111, p = 0.002, 95% confidence interval; 2.313-44.207). The duration of surgery of patient in the fracture table group was found to be higher than in the other groups, the CDA in the supine position group were found lower than in the other groups, and the TAD in the supine position group was found higher than in the other groups. Complications were mostly detected in patients who underwent surgery in the lateral decubitus position. (p<0,05)
Conclusion: We believe that it is necessary to be familiar with all methods, since it is very difficult to choose the most appropriate method according to the surgeon’s experience, the hospital’s facilities and conditions, and the patient’s clinical status.

Folk medicine is widely used in Angola, even for human African trypanosomiasis (sleeping sickness) in spite of the fact that the reference treatment is available for free. Aiming to validate herbal remedies in use, we have selected nine medicinal plants and assessed their antitrypanosomal ac-tivity. 122 extracts were prepared using different plant parts and solvents. 15 extracts from seven different plants exhibited in vitro activity against Trypanosoma brucei rhodesiense bloodstream forms >70% at 20 µg/ml. The dichloromethane extract of Nymphaea lotus (leaves and leaflets) and the ethanolic extract of Brasenia schreberi (leaves) had IC50 values ≤10 µg/ml. These two aquatic plants are of particular interest. They are being co-applied in the form of a decoction of leaves because they are considered by local healers as male and female of the same species, the ethnotaxon “longa dia simbi”. Bioassay-guided fractionation led to the identification of eight active molecules: gallic acid (IC50 0.5 µg/ml), methyl gallate (IC50 1.1 µg/ml), 2,3,4,6-tetragalloyl-glucopyranoside, ethyl gallate (IC50 0.5µg/ml), 1,2,3,4,6-pentagalloyl-β-glucopyranoside (IC50 20µg/ml), gossypet-in-7-O-β-glucopyranoside (IC50 5.5µg/ml), and hypolaetin-7-O-glucoside (IC50 5.7µg/ml) in B. schreberi, and 5-[(8Z,11Z,14Z)-heptadeca-8,11,14-trienyl] resorcinol (IC50 5.3µg/ml) not described to date in N. lotus. Five of these active constituents were detected in the traditional preparation. This work provides the first evidence for the ethnomedicinal use of these plants in the management of sleeping sickness in Angola.

Published: January 2024

Previously, we reported that metronidazole MICs are not dependent on the expression levels of nim genes in B. fragilis strains; and we also compared the proteomes of metronidazole-resistant laboratory B. fragilis strains to those of their susceptible parent strains. Here, we used RT-qPCR to correlate the expression levels of 18 candidate genes in a panel of selected, clinical nim gene-positive and -negative B. fragilis strains to their metronidazole MICs. Metronidazole MICs were correlated to the expression of certain tested genes. Specifically, lactate dehydrogenase expression correlated positively, whereas cytochrome fumarate reductase/succinate dehydrogenase, malate dehydrogenase, phosphoglycerate kinase redox and gat (GCN5-like acetyltransferase), and relA (stringent response) regulatory gene expressions correlated negatively with metronidazole MICs. This result provides evidence for the involvement of carbohydrate catabolic enzymes in metronidazole resistance in B. fragilis. This result was supported by direct substrate utilization tests. However, the exact roles of these genes/proteins should be determined in deletion–complementation tests. Moreover, the exact redox cofactor(s) participating in metronidazole activation need to be identified.
Flat Horizon D-Dimensional Black Holes in the Cubic Form of f(Q) Theory
Authors: Nashed Gamal Gergess Lamee
Published: January 2024

Given the AdS/CFT relationship, the study of higher-dimensional AdS black holes is extremely important. Furthermore, since the restriction derived from $f(Q)$'s field equations which prevents it from deriving spherically symmetric black hole solutions, the result is either $Q'=0$ or $f_{QQ}=0$. We derive static anti-de-Sitter black holes in $D$-dimensions using the cylindrical coordinate in the framework of the cubic form of $f(Q)$ gravity, where the coincident gauge condition is imposed \cite{Heisenberg:2023lru,Maurya:2023muz}. Within this study we are going to use the power-law ansatz which is the most viable according to observations where $f(Q)=Q+\frac{1}2\gamma Q^2+\frac{1}3\gamma Q^3-2\Lambda$, and the condition $D \geq 4$ is satisfied. Since these solutions lack a general relativity limit, they belong to a brand-new solution class, the characteristics of which are derived only from the non-metricity $Q$ modification. We investigate the singularities of the solutions by computing the values of different curvature and non-metricity invariants. We discover that the solutions indeed have a central singularity, but because of the f(Q) impact, it is softer than in the typical general relativity case. In conclusion, we compute thermodynamic parameters such as Gibbs free energy, Hawking temperature, and entropy. These thermodynamic calculations confirm that our model is stable.
Nourishing Conversations: Using Motivational Interviewing in a Community Teaching Kitchen to Promote Healthy Eating via a Food Is Medicine Intervention

Published: January 2024

It is well known that dietary choices impact both individual and global health. However, there are numerous challenges at the personal and systemic level to fostering sustainable healthy eating patterns. These barriers have emphasized the need for innovative approaches within minority communities, particularly those facing food insecurity, to help translate dietary recommenda-tions into practice. Food as Medicine is an approach that recognizes the potential to alleviate the burden of chronic diseases through a healthy diet that is customized to meet the needs of the indi-vidual. Key to implementing this approach are teaching kitchens, which offer an interactive envi-ronment for learning nutrition and cooking skills. Their curriculums are often rooted in Food as Medicine as well as Culinary Medicine, a similar approach. We have found that motivational in-terviewing (MI) techniques, which are primarily used to facilitate behavior change, are well-suited for implementing and maintaining dietary modification. In this commentary, we show how this has been done in a community-based teaching kitchen to empower individuals to make informed and sustainable dietary choices. In demonstrating the application of MI principles in this setting, we hope to offer an inclusive and sustainable way to help address the urgent need for healthier eating and its role in building healthier communities.
On the Parallelization of Square-Root Vélu’s Formulas
Authors: Chávez-Saab Jorge , Ortega Odalis , Pizarro-Madariaga Amalia
Published: January 2024

A primary challenge in isogeny-based cryptography lies in the substantial computational cost associated to computing and evaluating prime-degree isogenies. This computation traditionally relied on Vélu’s formulas, an approach with time complexity linear in the degree but which was further enhanced by Bernstein, De Feo, Leroux, and Smith to a square-root complexity. The improved square-root Vélu’s formulas exhibit a degree of parallelizability which has not been exploited in major implementations. In this study, we introduce a theoretical framework for parallelizing isogeny computations and provide a proof-of-concept implementation in C with OpenMP. While the parallelization effectiveness exhibits diminishing returns with the number of cores, we still obtain strong results when using a small number of cores. Concretely, our implementation shows that for large degrees it is easy to achieve speedup factors of up to 1.74, 2.54 and 3.44 for 2, 4 and 8 cores, respectively.

Published: January 2024

Bio sorption and biodegrading capacity as well as sorption of oil onto expanded perlites modified with oil-eating bacteria were studied. This investigation leveraged perlite as an oil absorbent, subsequently laden with oil-degrading micro-organisms, aiming to study not only oil spill absorption but also the eradication of oil spill. Findings from experiments with three different adsorbents - one devoid of microbes, one featuring perlite loaded with microbes, and one containing expanded perlite laden with microbes-indicate that expanded perlite, due to its large surface area and low density, presents an optimal environment for microbial growth and proliferation. Upon microbial colonization, the amount of oil absorption and removal escalated by 58% and 80.45%, respectively, compared to pre-expansion. Furthermore, microbial activity mitigated some oil contamination and decreased the surface tension between water and oil via production of surface active substances, thereby facilitating further separation of residual oil in the water.
Bad air quality raises mortality in honey bees, a concern for all pollinators

Published: January 2024

Human well-being relies significantly on the presence and role of pollinators, as they contribute to the vitality of ecosystems, support the reproduction of wild plants, increase crop yields, and strengthen overall food security​1​. While wild bee populations are dwindling​2​ due to climate and environmental shifts, there has been a notable 45% rise globally in managed honey bee colonies over the past five decades​3​. Given their economic significance, this focus on Apis Mellifera is attributed to their ability to serve as bioindicators of global pollinator health and ease of tracking. Consequently, honey bees have emerged as a keystone species requiring protection and conservation efforts. Here, we investigate the intricate relationship between air quality, vegetation density, wind speed, and honey bee mortality across North America. Using descriptive statistics and machine learning techniques, our findings underscored the honey bee's role as a bioindicator, with a higher Air Quality Index strongly correlating to increased mortality. Conversely, elevated greenness demonstrated a robust correlation with reduced mortality. Our results show how air quality and greenness strongly drive honey bee survival. Overall, our study offered a beacon of hope: increasing greenery within the region facing poor air quality and improving management tools and practices can significantly alleviate the impact of deteriorating air quality, providing a vital solution to safeguard our essential pollinators.
Taphonomy of Quaternary Pectinidae and a Comparison With Early Permian Shells
Authors: Neto Hugo Schmidt , Horodyski Rodrigo Scalise
Published: January 2024

Actuopaleontology has been widely developed to improve the interpretations of the fossil record. In the Paraná Basin, a pectinid-dominated fossil record marks the Late Paleozoic strata (Upper Carboniferous, Lower Permian), an opportunity to compare their taphonomic signatures with Quaternary valves through actualistic research. This research aims to improve the biostratinomic knowledge of pectinid fossil concentrations, leading to better environmental and ecological interpretations of the fossil record. Thus, the present study is based on the taphonomy of 173 valves of Aequipecten tehuelchus. The Quaternary valves were collected on the foreshore of the coastal plain of the Rio Grande do Sul state. Fragmentation degree, flat/convex valve rate, dissolution, bioerosion (i.e., borings and drill holes), and incrustation were quantified. Following, Quaternary pectinid data were compared with available information on the Lower Permian pectinids from the Rio Bonito Formation (Paraná Basin). Not all signatures imprinted in the Quaternary material were observed in Permian molds. However, physical and biological damages were preferentially observed in both Quaternary and Permian samples. Quaternary pectinids on the modern beach suggest the high transportability and durability of their hard skeletons. These taphonomical and sedimentary processes increase the time-averaging and spatial-averaging since Lower Permian pectinids storm-assemblage was registered in the estuarine setting. Furthermore, both deposits studied here were generated during an icehouse/greenhouse transition, and the spatial averaging may have been increased due to the sea-level oscillation and consequent erosion/reworking in marginal marine environments.
Global economic impact of weather variability on the rich and the poor

The distribution of temperature and precipitation has been shown to impact economic productivity all around the world.
These heterogeneous patterns change under future warming and impact consumers not only locally but also remotely through supply chains and trade relations.
Due to the possibility of a non-linear economic response, these effects are difficult to quantify and have been subject to limited empirical assessment focusing on direct impacts of weather extremes.
Here we show in numerical simulations of weather-induced production disruptions (of more than 7000 profit-maximising producers and utility-optimising consumers with more than 1,8 million supply linkages)
that, under present-day climatic conditions, consumption loss risks resulting from production disruptions propagating through the economic network are larger for lower than for higher income groups within countries. Comparison between countries shows that risks are larger for medium income countries than for low and high income countries, which emerges from differing trade dependencies as well as heterogeneous exposure and response.
Projecting observed econometric relations of weather variability and economic productivity until 2040, we find an amplification of loss risks due to near-term climate change in most regions. This amplification increases with income for middle and high income countries, while it is homogeneous across income groups in low-income countries.
Global warming thus poses an increasing challenge to consumers through supply chains around the globe which needs to be addressed by fostering resilience. To avoid further harm to productivity and consumer welfare the climate has to be stabilised.

Background
This study assesses the effectiveness of a physical activity intervention using a human-centered participatory co-design in a rural community. In collaboration with a campus-community partnership, the intervention involves children in the design process to address declining physical activity levels among middle school students. The primary objective is to evaluate the feasibility of this innovative intervention.
Methods
Twenty-four middle school students participated in a mixed-methods pre-post intervention during physical education classes. The inclusive intervention included elements like sport-based youth development, individualized goal setting, physical activity monitoring, pedometer usage, and health education. Data were collected at baseline (T1) and post-intervention (T3), with intermediate measures during the intervention (T2). Analytical methods encompassed descriptive statistics, correlations, repeated measures ANOVA, and thematic analysis. Qualitative data were integrated through semi-structured interviews.
Results
Key findings indicate robust feasibility, with intervention-related scores (FIM, AIM, and IAM) consistently surpassing the "good" threshold and 100% retention and recruitment success. Additionally, participants showed significant physical performance improvement, shifting from the 25th to the 50th percentile in the 6-minute walk test (p < 0.05). Autonomy and competence remained high, reflecting positive perceptions of program practicality. Nutrition knowledge, initially low, significantly improved post-intervention (p < 0.01), highlighting the efficacy of targeted nutritional education in Hoosier Sport.
Conclusions
This study pioneers a community-focused model for physical activity intervention in under-resourced rural settings. Positive participant feedback, coupled with improvements in physical fitness and psychosocial factors, highlights the potential of the co-design approach. The findings offer valuable insights and a practical template for future community-based research, signaling the promising impact of such interventions on holistic well-being. This research lays the foundation for subsequent phases of the ORBIT model, emphasizing collaborative, community-driven approaches to address the complex issue of declining physical activity levels among adolescents.
Effects of Parental Intimacy and Self-disclosure on Dyadic Coping in Parents of Children with Autism Spectrum Disorder Entering School

Published: January 2024

Autism spectrum disorder (ASD) is a pervasive and often difficult health condition, especially during the stage in which children with ASD enter school, which can have ripple effects throughout family relationships. This study applied relational turbulence theory (which addresses communication in intimate relationships) and the actor–partner interdependence model, to examine how self-disclosure communication and relationship intimacy between parents of children with ASD affects dyadic coping during a major transitional period in their child’s life. Transition processing includes parental self-disclosure and parental intimacy, which can help parents navigate difficult life events by promoting connection, interaction, and confidence in the relationship. A total of 201 married couples parenting a child with ASD who was beginning school or who had started school in the past six months completed three questionnaires and provided demographic information. The study examined the effects of partners’ intimacy and disclosure levels on their own and their spouses’ experiences of relational uncertainty, changes in interdependence, and relational turbulence. The findings suggest that parental intimacy and self-disclosure in dyadic coping significantly affect some relationship qualities. In addition, individuals’ perceptions of their spouses’ dyadic coping abilities were a stronger predictor of relational turbulence than self-reported dyadic coping. This study’s results provide several implications for understanding how married partners can protect their marriage when dealing with their child’s health-related transitions.

Apricot fruit is of great importance due to its high quality, and the possibility of exporting it from an economic point of view. In order to maintain the quality of apricots, in addition to observing the principles of horticulture, the issue of proper storage after harvesting and managing the product until the time of sale is inevitable. In this research, the effect of microwave radiation and potassium permanganate to increase yield of apricots of the late fruiting Noori cultivar during 45 days of storage at a temperature of 2 0C and a relative humidity of 85 to 95% was studied. For this purpose, an experiment was conducted with microwave radiation (control (0)180 and 360 W), storage time (15, 30 and45 days) and 3 potassium permanganate (control − 3 and 5 g) on apricot cv. Noori. Results showed that the appearance quality and taste of the fruit improved under the influence of microwave radiation. The TSS/TA ratio increased with increasing storage time, while the application of microwave radiation and potassium permanganate decreased the fruit maturity index. The use of microwave radiation and potassium permanganate reduced the rate of fruit rot. The use of microwave radiation and potassium permanganate treatments increased the firmness of the fruit tissue. The results of this research showed that the use of microwave radiation as a type of heat treatment and potassium permanganate can be introduced as an effective strategy in the technology after harvesting apricot fruits.

Background
After the Covid-19 pandemic, there has been a notable increase in people's demand for and usage of functional foods at pharmacy retailers. Consequently, the role of drug sellers in providing guidance and recommendations for the use of functional foods has become increasingly significant. However, the knowledge of drug sellers about functional foods remains limited, often resulting in inaccurate or inappropriate advice to consumers.
Objectives
The study was conducted to analyze the knowledge and behavior of drug sellers in selling functional foods at pharmacy retailers in the Mekong Delta, Vietnam. Subjects and
methods
A cross-sectional descriptive study was conducted through a survey of drug sellers at pharmacy retailers in the Mekong Delta during the period from June 2022 to March 2023. The questionnaire was constructed using the following factors based on the theory of planned behavior (TBP) model, consisting of 32 observed variables.
Results
Of the 575 drug retailers participating in the study, drug sellers with good knowledge accounted for 52%. The scale exhibited reliability, with both Cronbach's Alpha coefficients exceeding 0.7 and variable-total correlation surpassing 0.3. Exploratory Factor Analysis indicated that the constructed scale is of high quality. Multivariate regression analysis showed that “Perceived behavioral control” affects the selling behavior of functional foods among drug sellers at drug retailers.
Conclusion
Considering the selling behavior of functional foods by drug sellers during their professional practice is vital to ensure the health benefits of consumers and promote the development of the functional food market.
