Published: October 2024

AbstractThe rise of flexible and wearable electronics has spurred advancements in printed, flexible micro-supercapacitors for energy storage. This study presents the fabrication of flexible micro-supercapacitors using a novel nanocomposite of tin dioxide grown on layered reduced graphene oxide through one-pot in situ synthesis. The conductive functional ink, formulated by mixing the nanocomposite, is effectively utilized in screen-printing technology. The resulting micro-supercapacitors, particularly the SG-1 variant, demonstrate impressive electrochemical performance. The nanocomposites show exceptional versatility across various electrolytes, including alkaline, acidic, and quasi-gel electrolytes with a polyvinyl alcohol matrix infused with potassium hydroxide. An in-depth comparison of their efficacy in these electrolytes highlights the most suitable configurations for optimal performance. At a scan rate of 5 mV s−1, SG-1 achieves areal capacitances of 148.7 mF cm−2 and 87.7 mF cm−2 in the 1 M KOH and polyvinyl alcohol infused with 1 M KOH quasi-gel electrolyte. Additionally, SG-1 in the gel electrolyte demonstrates remarkable energy density of 11.7 mWh cm−2 at power density of 490 mW cm−2. Notably, the fabricated micro-supercapacitors exhibit excellent capacitive retention of 89.5% even after undergoing 5000 cycles of charge–discharge, underscoring their robustness and long-term stability for practical applications in flexible and wearable electronics.

Published: October 2024

AbstractPrescribed burning is commonly used to maintain forest ecosystem functions and reduce the risk of future wildfires. Although many studies have investigated the response of microbial community to wildfires in forest ecosystems, the effects of prescribed burnings on soil microbial community structure are less studied. It is also unclear that how post-fire soil physiochemical properties changes affected soil microbial communities. Here, we studied the impacts of prescribed burning on soil microbiome in three typical temperate forests of northern China by collecting soil physicochemical and high-throughput sequencing for 16S rRNA and 18S rRNA was applied to analyze the diversity and community composition of soil microbes (bacteria and fungi). Compared with pre-fire condition, prescribed burning significantly decreased Chao1 index and altered soil bacterial communities (P < 0.05), whereas it had no significant effect on fungal diversity and community structure of the (P > 0.05). Planctomycetes and Actinobacteria made the greatest contributions to the bacterial community dissimilarity between the pre-fire and post-fire conditions. The main variables influencing the post-fire soil microbial community structure are soil pH, available phosphorus, total nitrogen, and the ratio of soil total carbon to soil total nitrogen, which could account for 73.5% of the variation in the microbial community structure in these stands. Our findings demonstrated a great discrepancy in the responses of bacteria and fungi to prescribed burning. Prescribed burning altered the soil microbial structure by modifying the physicochemical properties. Our results pointed that it is essential to evaluate the impact of prescribed burnings on forest ecosystem functions. These findings provide an important baseline for assessing post-fire microbial recovery in the region and offer critical guidance for restoration efforts.
Influencer marketing effectiveness: A meta-analytic review

Published: October 2024

Abstract
Influencer marketing significantly impacts consumer behavior and decision-making. However, identifying the drivers of influencer marketing effectiveness and conditions that enhance their impact remains challenging. This meta-analysis, which synthesizes 1,531 effect sizes from 251 papers, assesses influencer marketing effectiveness by examining its antecedents, mediators, and moderators. Building on the persuasion knowledge model to develop and test a framework, we identify post, follower, and influencer characteristics as key antecedents impacting both non-transactional (i.e., attitude, behavioral engagement, and purchase intention) and transactional (i.e., purchase behavior and sales) marketing outcomes. For non-transactional outcomes, follower characteristics (social identity) have the strongest effects on consumer attitudes and behavioral engagement, while post characteristics (informational value and hedonic value) exert stronger effects on purchase intention. For transactional outcomes, influencer characteristics (influencer communication) have the strongest effects on purchase behavior. These antecedents also affect marketing outcomes indirectly through persuasion knowledge and source credibility. Moderation results indicate that direct and indirect effects of antecedents depend on social media types (i.e., nature of connection and usage) and product types (i.e., information availability and status-signaling capability). These results consolidate and advance the literature and offer insights into enhancing the effectiveness of influencer marketing.

Abstract
In this study, the possibility of modifying a multi-layer biopolymer active system to reduce permeability to gases of a biodegradable material with potential application in food technology was analysed. A four-layer biopolymer film was used, wherein the initial two layers comprised furcellaran, whilst the subsequent two layers were a mixture of chitosan and gelatin. The film was modified with active ingredients, including silver nanoparticles (AgNPs), montmorillonite, a curcumin-capsaicin mixture and gelatin hydrolysate. The film formed an integrated, semi-rigid packaging system together with the tray, which was developed from tea brewing waste and biopolymers. Application properties were assessed by analysing mechanical parameters, key to the assessment of their quality, proving that the active ingredients significantly improved the strength properties. There was an almost twofold increase in modulus of elasticity values compared to the control film. The permeability against oxygen was also assessed as the main performance characteristic of the packaging and was only 13.64 ± 3.92 [cm3/m2 × 24 h]. The impact of the applied material innovation in packaging on the freshness of food products was also evaluated by analysing the microbiological purity of stored Salmo Salar fillet. The active, biodegradable packaging extended the shelf-life of salmon by 6 days compared to the low-density polyethylene (LDPE) film. Toxicity analysis has shown that the used active ingredients are safe for the environment and consumers.
Circle-circle intersection. A universal method for solving typical surveying problems
Authors: Gargula Tadeusz 
Published: October 2024

AbstractThe research problem of the article is to devise a universal mathematical procedure for calculating point coordinates from typical planar surveying measurements. The proposed solution involves calculating the intersection points of two circles with radii equal to the measured distances (the distance-distance intersection problem). The author demonstrates a straightforward method for reducing every typical surveying problem to the distance-distance intersection form. The procedure also verifies the accuracy of the calculated coordinates. The derived equations were tested numerically using practical examples. The devised procedure will be integrated into an exhaustive numerical algorithm for diverse surveying problems regardless of the geometric approach during measurements.
PDFO: a cross-platform package for Powell’s derivative-free optimization solvers
Authors: Ragonneau Tom M. , Zhang Zaikun 
Published: October 2024

AbstractThe late Professor M. J. D. Powell devised five trust-region methods for derivative-free optimization, namely COBYLA, UOBYQA, NEWUOA, BOBYQA, and LINCOA. He carefully implemented them into publicly available solvers, renowned for their robustness and efficiency. However, the solvers were implemented in Fortran 77 and hence may not be easily accessible to some users. We introduce the PDFO package, which provides user-friendly Python and MATLAB interfaces to Powell’s code. With PDFO, users of such languages can call Powell’s Fortran solvers easily without dealing with the Fortran code. Moreover, PDFO includes bug fixes and improvements, which are particularly important for handling problems that suffer from ill-conditioning or failures of function evaluations. In addition to the PDFO package, we provide an overview of Powell’s methods, sketching them from a uniform perspective, summarizing their main features, and highlighting the similarities and interconnections among them. We also present experiments on PDFO to demonstrate its stability under noise, tolerance of failures in function evaluations, and potential to solve certain hyperparameter optimization problems.

Abstract
Following the use of sugar beet pulp that was retrospectively found to be predominantly contaminated with zearalenone (ZEN) in diets of reproducing sows largely exceeding the EU-guidance value for critical ZEN concentration of 0.25 mg/kg, farmers did not report any changes in the reproductive performance of sows. Thus, the aim of the study was to verify this guidance value in a dose–response setup by using sugar beet pulp as a ZEN source hitherto not considered a risky feedstuff additionally characterized by comparatively low levels of deoxynivalenol. A total of 90 sows was equally allocated to one of the three feed groups during experimental lactation 1 and up to 40 days after insemination: CON with a minimal ZEN concentration, ZEN1 with a target concentration of 250 µg ZEN/kg feed, and ZEN2 with a target concentration of 500 µg ZEN/kg feed. Thereafter, all sows received the same feed without ZEN for the rest of gestation, and the following lactation for testing of putative carry-over effects resulting from previous ZEN exposure. Exposure of sows to ZEN with blood serum as an indicator was linearly related to dietary ZEN concentrations. Reproductive and zootechnical performances of sows were only affected by ZEN exposure at weaning weight. Clinical-chemical parameters indicated no clear effect of ZEN exposure. An influence of ZEN on the occurrence of tail and ear injuries (not necrosis) in piglets and lesions on the mammary complexes in sows is possible. The influence of a ZEN concentration above the EU guidance value on the study farm can therefore not be neglected.
A novel approach to assessing food insecurity for small geographic areas using household living budgets
Authors: Montalvo Cesar , Lancaster Vicki , Salvo Joseph J. , Shipp Stephanie 
Published: October 2024

AbstractThe USDA Economic Research Service has monitored food insecurity at national and state levels since 1995 using the Current Population Survey Food Security Supplement. But if a food insecurity measure is to inform action and target interventions, it must be constructed for smaller geographic levels that consider geographic price differences. This article constructs a novel measure of food insecurity using an alternative approach based on financial needs of households, known as the household living budget (HLB). The HLB is defined as the income required to satisfy a household's essential needs, enabling it to maintain a modest yet sufficient standard of living while covering federal and state income taxes. The HLB is constructed at the census tract level and incorporates three key determinants of food insecurity: household size and composition, household income, and food costs. We demonstrate how the HLB along with publicly available data can be used to construct a food insecurity measure using a residual income approach to assess if households are able to afford paying for food expenditures and assess the qualification thresholds of the Supplemental Nutrition Assistance Program (SNAP). Food insecurity estimates are obtained for households in Washington, D.C. and benchmarked to regional results provided by a survey sponsored by the Capital Area Foodbank.
Decoupling anthropogenic, climatic, and tectonic factors in the hydrology of playa-lakes in a semi-arid, tectonically active region (betic orogen, southern Spain)
Authors: Rodríguez-Rodríguez M. , Jiménez-Bonilla A. , Díaz-Azpiroz M. , Gázquez F. 
Published: October 2024

AbstractHere, we explore the dynamic interplay of climate, tectonic forces and human impacts, that have shaped the current hydrology of the 27 main endorheic continental playa-lakes in southern Spain, most of them protected as Natural Reserves. This research offers a thorough examination of the hydro-geomorphic, geochemical, and tectonic characteristics that influenced the development of these wetlands. We introduce and apply several hydro-morphological indices that effectively characterize the hydrological functioning of these wetlands. Importantly, the examination of the geological setting and analysis of recent tectonics has been found to be effective in reconstructing the evolution of some of the major playa-lakes, including Fuente de Piedra playa-lake and El Gosque playa-lake. Lastly, the analysis of satellite information using the online tool water occurrence change intensity (WOCI) of Surface Water Explorer in the studied playa-lakes was found to be inconsistent in the long-term analysis. Enhanced attention is required to refine the WOCI tool, thereby ensuring a more precise depiction of wetland dynamics in the Mediterranean. Fine-tuning will better represent complex behaviors, thus improving its utility for monitoring and managing wetlands in the region.

AbstractWith the advent of robot-assisted surgery, user-friendly technologies have been applied to the da Vinci surgical system (dVSS), and their efficacy has been validated in worldwide surgical fields. However, further improvements are required to the traditional manipulation methods, which cannot control an endoscope and surgical instruments simultaneously. This study proposes a speech recognition control interface (SRCI) for controlling the endoscope via speech commands while manipulating surgical instruments to replace the traditional method. The usability-focused comparisons of the newly proposed SRCI-based and the traditional manipulation method were conducted based on ISO 9241-11. 20 surgeons and 18 novices evaluated both manipulation methods through the line tracking task (LTT) and sea spike pod task (SSPT). After the tasks, they responded to the globally reliable questionnaires: after-scenario questionnaire (ASQ), system usability scale (SUS), and NASA task load index (TLX). The completion times in the LTT and SSPT using the proposed method were 44.72% and 26.59% respectively less than the traditional method, which shows statistically significant differences (p < 0.001). The overall results of ASQ, SUS, and NASA TLX were positive for the proposed method, especially substantial reductions in the workloads such as physical demands and efforts (p < 0.05). The proposed speech-mediated method can be a candidate suitable for the simultaneous manipulation of an endoscope and surgical instruments in dVSS-used robotic surgery. Therefore, it can replace the traditional method when controlling the endoscope while manipulating the surgical instruments, which contributes to enabling the continuous surgical flow in operations consequentially.

AbstractThe normalized Ricci flow converges to a constant curvature metric for a connected Kaehlerian slant submanifold in a complex space form if the squared norm of the second fundamental form satisfies certain upper bounds. These bounds include the constant sectional curvature, the slant angle, and the squared norm of the mean curvature vector. Additionally, we demonstrate that the submanifold is diffeomorphic to the sphere $$\mathbb {S}^{n_1}$$

Random balancing-like sequences
Authors: Patra Asim , Panda Gopal Krishna 
Published: October 2024

AbstractA balancing-like sequence is a binary recurrence sequence which generalizes the balancing sequence and the sequence of nonnegative integers. This sequence, under certain assumptions, may be used to describe the growth of fortune of a person engaged in some business or profession. Since, in any business or profession, the growth is influenced by many uncertainties, it is more natural to induce some sort of randomness in the balancing-like sequences. If, in a balancing-like sequence, the growth rate is assumed to be a random variable, the resulting sequence will be a stochastic process and the sequence of expectations, in many cases, cannot be described as a binary recurrence sequence. In some cases, the growth rate of expectations increases without limit while, in some cases, it remains finite.

Novel results from quadratically nonlinear elastic wave models using Murnaghan’s potential
Authors: Hameed Hamza , Zaman F. D. , Ahmad Shahbaz , Ali Hassan 
Published: October 2024

AbstractIn this article, we study one, two and three-dimensional nonlinear elastic wave equations using quadratically nonlinear Murnaghan potential. We employ two effective methods for obtaining approximate series solutions the Adomian decomposition and the variational iteration method. These methods have the advantage of not requiring any physical parametric assumptions in the problem. Finally, these methods can generate expansion solutions for linear and nonlinear differential equations without perturbation, linearization, or discretization. The results obtained using the adopted methods along various initial and boundary conditions are in excellent agreement with the numerical results on MATLAB, which show the reliability of our methods to these problems. We came to the conclusion that our methods are accurate and simple to use.

Abstract
Background
Hip fracture is a common event in older adults, leading to an increased risk of mortality, disability, and higher healthcare costs. Early in-hospital rehabilitation after surgery within orthogeriatric units may improve outcomes with limited incident complications even in the oldest old. We aimed to determine the prevalence and predictors of non-adherence to early rehabilitation in the orthogeriatric unit of an Italian tertiary hospital and its impact on outcomes and setting at discharge.

Methods
Retrospective observational single-centered cohort study. Patients aged ≥ 65 years admitted to the orthogeriatric unit for hip fracture who underwent surgery between April 2019 and October 2020 were considered eligible if able to walk autonomously or with assistance and independent in at least 2 Basic Activities of Daily Living. Along with sociodemographic and geriatric variables, characteristics of surgery and rehabilitation, in-hospital complications and functional outcomes at discharge were collected. The primary outcome was non-adherence to the early in-hospital rehabilitation program.

Results
Among 283 older patients (mean age 82.7 years, 28.6% male), non-compliance with physical therapy was assessed in 49 cases (17.3%), characterized by worse pre-fracture clinical, cognitive, and functional status and showing worse outcomes in terms of mobilization at discharge. After multivariable analysis, non-adherence was independently associated with the onset of delirium (OR 5.26, 95%CI 2.46–11.26; p < 0.001) or infections after surgery (OR 3.26, 95%CI 1.54–6.89; p < 0.001) and a systolic blood pressure at admission < 120 mmHg (OR 4.52, 95%CI 1.96–10.43, p < 0.001).

Conclusions
Pre-fracture poor cognitive and functional status, along with lower systolic blood pressure, seem to make some patients more vulnerable to in-hospital complications (mainly delirium and infections) and negatively affect the adherence to physical therapy and, by consequence, clinical outcomes of rehabilitation.
