AbstractPineapple leaves, a raw agricultural waste biomass material, were used to synthesize microcrystalline cellulose (MCC) through extraction, bleaching, and hydrolysis. Then, the MCC was mixed with different concentrations of silver nitrate solution to create a regenerated cellulose composite sheet loaded with silver nanoparticles (AgNPs) and used as a hydrogen sulfide (H2S) detector. The physicochemical properties of the cellulose composite sheet loaded with AgNPs before and after H2S exposure were analyzed using various advanced equipment. The H2S adsorption experiments revealed that the composite sheet underwent a visible change from yellow to brown upon exposure to H2S gas. The range for accurate prediction of the H2S concentration was 20–50 ppm. When temperature in the surroundings of the composite sheet was lower and the H2S gas concentration was higher, the color became darker (dark brown). The relative humidity conditions rarely impacted the sensitivity of color change in the cellulose composite sheet. The stability experiment showed that the cellulose composite sheet had exceptional stability at storage temperatures of 4 and 25 °C for 30 days. This composite sheet mixed with AgNPs has the potential to be used as a gas test strip to detect H2S, such as in food packaging.
Enhancing the Properties of Self‐Healing Gelatin Alginate Hydrogels by Hofmeister Mediated Electrostatic Effect
Authors: Das Sougat , Majumdar Saptarshi 
Published: October 2023

AbstractThe cross‐linker‐free hydrogels have gained attention due to their lack of need for chemically modified polymers, resulting in better biocompatibility. The hydrogel properties can be enhanced by altering physical forces such as electrostatics and H‐bonds. Tuning the physical interactions between polymers, salts, and plasticisers can unlock new horizons in material properties. This article examines four different salts and mixtures to determine their impact on gelatin‐alginate biomaterial design. Drug release, swelling, and rheological properties are represented using a 3‐D plot, and optimum samples are identified. It is concluded that kosmotropes yield better release and swelling results than chaotropes. The physical interactions of these salts with polymers are explained using DLS and FTIR/ATR studies, and these findings are corroborated with release, swelling, and rheological analyses. Another aspect of the biomaterial, self‐healing property, is also considered. A 3‐D plot is prepared using release kinetics, gel strength, and recovery percentage (three important factors for self‐healing hydrogels). Chaotropes are identified as better candidates for self‐healing behaviour. However, when considering gel strength, release, and self‐healing, kosmotropes are favourable. Hence, different salts can be selected based on the desired application for hydrogels. It is also concluded that electrostatic forces hinder the formation of H‐bonds between polymer chains.

Published: October 2023

AbstractDinuclear bisNHC (bis(N‐heterocyclic carbene)) gold(I) complexes 3 a and 4 a of general formula [Au2Br2(bisNHC)] were tested as catalysts in the cycloisomerization of N‐(prop‐2‐yn‐1‐yl)benzamide and in the hydromethoxylation of 3‐hexyne in the presence of silver(I) activators bearing different counteranions. The catalytic performance of mononuclear NHC complexes (1 a, 2 a) in the same reactions was also studied. The results highlighted the fundamental role of both NHC ligand and counterion in the catalytic cycles and activation process: dinuclear catalysts exhibit higher initial activity even under milder conditions but suffer in terms of stability with respect to mono NHCs. Furthermore, a new dinuclear bisNHC gold(I) complex 4 b of general formula [Au2(OTs)2(bisNHC)] (OTs=p‐toluenesulfonate) was successfully synthesized and characterized by means of NMR and ESI‐MS analyses.

Published: October 2023

SummaryIn the present scenario, wireless body area network (WBAN) use case has gone beyond medical monitoring (e.g., E‐Healthcare) and has become a vital part of our daily lives. WBANs, applied in E‐Healthcare systems, extract the physiological parameters through the implanted (in‐body) and/or wearable (on‐body) sensors applied to the human body and route them to the remote server in a systematized and well‐grounded manner. Thus, routing is the most primitive and non‐trivial task in WBANs for prompt and proper delivery of sensed data. The design of routing protocol is crucial for efficacious communication and high network performance. Therefore, the target of this paper is to present an all‐encompassing taxonomy of the state‐of‐the‐art routing protocols in WBANs. Firstly, this paper provides an insight into WBANs and their related projects. Next, WBAN routing challenges are explored, and after clustering these challenges based on their operating mechanism, the routing protocols are categorized into eight categories, which correspond to cluster‐ and tree‐based, cross‐layer‐based, fuzzy‐based, interference‐based, posture‐based, QoS‐based, SDN‐based, and temperature‐based routing protocols. Furthermore, comparison tables highlighting the goals, strengths, limitations, and novelty of each protocol, along with a qualitative comparison table of the routing protocols for each category based on their features are furnished. This exhaustive survey can serve as a starting point for WBAN researchers, as open research issues have been highlighted in the discussion section.

AbstractINTRODUCTIONTo reduce demands on expert time and improve clinical efficiency, we developed a framework to evaluate whether inexpensive, accessible data could accurately classify Alzheimer's disease (AD) clinical diagnosis and predict the likelihood of progression.METHODSWe stratified relevant data into three tiers: obtainable at primary care (low‐cost), mostly available at specialty visits (medium‐cost), and research‐only (high‐cost). We trained several machine learning models, including a hierarchical model, an ensemble model, and a clustering model, to distinguish between diagnoses of cognitively unimpaired, mild cognitive impairment, and dementia due to AD.RESULTSAll models showed viable classification, but the hierarchical and ensemble models outperformed the conventional model. Classifier “error” was predictive of progression rates, and cluster membership identified subgroups with high and low risk of progression within 1.5 to 3 years.DISCUSSIONAccessible, inexpensive clinical data can be used to guide AD diagnosis and are predictive of current and future disease states.HIGHLIGHTS
Classification performance using cost‐effective features was accurate and robust
Hierarchical classification outperformed conventional multinomial classification
Classification labels indicated significant changes in conversion risk at follow‐up
A clustering‐classification method identified subgroups at high risk of decline
The bidirectional associations between self‐esteem and problematic eating behaviors in adolescents

AbstractObjectiveTheories propose that low self‐esteem and problematic eating behaviors (PEBs) negatively impact each other. While previous studies suggested bidirectional associations between self‐esteem and PEBs, they did not separate within‐person from between‐person associations. Therefore, this prospective study investigated the within‐person bidirectional associations between self‐esteem and four PEBs in adolescence, while accounting for between‐person differences.MethodWe used two independent longitudinal samples of Dutch adolescents, each including three annually collected waves of data. Sample 1 consisted of 1856 adolescents (Baseline: 50.4% males; Mage = 13.79 years, SDage = 0.72), with measures of self‐esteem, emotional eating, restrained eating, and loss of control (LOC) while overeating. Sample 2 consisted of 555 adolescents (Baseline: 49.7% males; Mage = 13.13 years, SDage = 0.68), with measures of self‐esteem and LOC eating. The data were analyzed using random intercept cross‐lagged panel models (CLPMs).ResultsWithin persons, lower self‐esteem was associated with higher emotional and restrained eating (both Sample 1) one year later, and vice versa. Self‐esteem did not predict, nor was predicted by, LOC while overeating (Sample 1) or LOC eating (Sample 2). Between persons, self‐esteem was negatively correlated with all PEBs (Samples 1 and 2).DiscussionWe found within‐person bidirectional associations between low self‐esteem and emotional and restrained eating (but not LOC while overeating/LOC eating), and between‐person correlations between low self‐esteem and all PEBs. These results have theoretical and practical implications. Within‐person processes clarify underlying mechanisms that explain the occurrence of PEBs; between‐person associations are important to identify adolescents at risk of PEBs.Public SignificanceWhile theories indicate that low self‐esteem and PEBs are inversely associated within individuals, empirical studies have not disentangled within‐person processes from between‐person differences. This study addressed this disparity, finding that lower self‐esteem was bidirectionally associated with higher emotional and restrained eating (but not LOC eating) within persons. These findings suggest that enhancing self‐esteem is a viable option for prevention and intervention.
Elevated temperatures shift flower head height distributions and seed dispersal patterns in two invasive thistle species
Authors: Drees Trevor H. , Shea Katriona 
Published: October 2023

AbstractClimate change may significantly alter how organisms disperse, with implications for population spread and species management. Wind‐dispersed plants have emerged as a useful study system for investigating how climate change affects dispersal, although studies modeling wind dispersal often assume propagules are released from a single point on an individual. This simplifying assumption, while useful, may misestimate dispersal. Here, we investigate the effects of climate change on dispersal distances and spread rates, examining how these quantities shift when accounting for all points of seed release on an individual. Using the wind‐dispersed invasive thistles Carduus nutans and Carduus acanthoides, we quantify temperature‐driven shifts in the distribution of flower head heights using a passive warming field experiment, and estimate how these shifts affect dispersal using the Wald analytical long‐distance (WALD) model; for C. nutans, we use existing demographic data to simulate how these shifts affect population spread rates. We also compare dispersal distances for both warmed and ambient temperature plants, considering the entire distribution of flower head heights versus the common assumption of point‐source seed release at the maximum height. For experimentally grown individuals, an ~0.6°C higher growing temperature increased mean and maximum flower head height by 14.1 cm (15.0%) and 14.0 cm (13.2%), respectively, in C. nutans and by 21.2 cm (26.6%) and 31.8 cm (36.7%), respectively, in C. acanthoides. Seeds from warmed individuals were more likely to exceed a given dispersal distance than those from their unwarmed counterparts; warmed C. nutans and C. acanthoides seeds were on average 1.36 and 1.71 times as likely, respectively, to travel 10 m or more in dispersal simulations, with this disparity increasing at longer dispersal distances. For C. nutans, increased growing temperatures boosted simulated rates of population spread by 42.2%, while assuming dispersal from a maximum height point source rather than the true distribution of flower head heights increased simulated spread by up to 28.5%. Our results not only demonstrate faster population spread under increased temperatures, but also have substantial implications for modeling such spread, as the common simplifying assumption of dispersal from a single maximum height source may substantially overestimate spread rates.

Published: October 2023

AbstractLayered shales exist widely and are often encountered during shale gas development. However, the mechanical response of layered shales is significantly affected by the existence of beddings, resulting in the obvious anisotropy characteristics regarding deformation, strength and failure mode. To clarify the underlying mechanisms of shale anisotropy that control the safety of engineering projects, the numerical simulation and theoretical analysis were conducted. The results show that with the growth of confining pressure, the compressive resistance of shales gradually increases, the shear fractures govern the instability and the anisotropy index decreases. Furthermore, several strength criteria for layered rock masses were summarized, and the modified Jaeger strength criterion was proposed by introducing the anisotropic parameter . It can effectively reflect the failure modes and strength features of layered shales under triaxial conditions with a higher accuracy. Besides, the variation of cohesion and internal friction angle of layered shale samples was comprehensively analysed under the triaxial conditions. Clearly, as the inclination angle of bedding planes increases, the cohesion of layered shales first decreases, but then increases under triaxial compression, showing the ‘U’‐shaped changing trend. Additionally, the internal friction angle of layered shales gradually increases with the increase in the inclination of bedding planes.

AbstractThe internet of things (IoT) relies on fifth generation (5G) networks as the foundation for interconnecting devices. Wireless networks are an essential component of 5G‐IoT technology, as they provide the means to interconnect devices and transmit data wirelessly. The performance of the wireless network, including its capacity, integrity, bandwidth, and latency, is critical in ensuring the reliable and secure transmission of data in 5G‐IoT. 5G is being developed with the goal of delivering exceptionally high capacity, solid integrity, high bandwidth, and low latency. With the development and innovation of new approaches for 5G‐IoT, new significant security and privacy concerns are certain to arise. As a result, secure data transmission mechanisms will be required as the foundation for 5G‐IoT technologies in order to solve these emerging difficulties. Deoxyribonucleic acid (DNA) cryptograms encrypt data by utilizing it as a carrier and biological technology. On an 8 by 8 multiantenna single carrier frequency division multiple access (SC‐FDMA) wireless system, we evaluate and compare the performance of DNA sine map‐based encrypted images using three different modulation algorithms: 16‐QAM, 16‐PSK, and 16‐DPSK. We also determine the bit error rate (BER) value for different signal to noise ratio (SNR) by analyzing the decrypted image's modulation performance. The methods minimum mean square error (MMSE), minimum mean error square successive interference cancelation (MMSE‐SIC), and zero‐forcing (ZF) are utilized for signal detection. Simulations in MATLAB reveal that the system is very effective and reliable when tested with MMSE‐SIC signal detection, 16‐QAM modulation, and low‐density parity check (LDPC) channel coding.

AbstractObjectiveAlthough infectious pathogens are predominant factors for inducing and maintaining immune system disorders, there exist few reports establishing the significant correlation between Helicobacter pylori (H. pylori) infection and Sjogren's syndrome. This study aims to demonstrate the correlation between Sjogren's syndrome and H. pylori infection in patients, highlighting various clinical characteristics and risk factors.MethodsA single‐center retrospective observational study was conducted in patients (n = 224) admitted from January 1, 2012, to February 10, 2021, in the First Affiliated Hospital of Wenzhou Medical University (Wenzhou, China). All the recruited subjects with Sjogren's syndrome and H. pylori infection were only included by validating the available medical records online.ResultsIn this study, a total of 224 patients from January 1, 2012, to February 10, 2021, were diagnosed with Sjogren's syndrome. Among them, 94 patients (41.96%) with Sjogren's syndrome were infected with H. pylori. Accordingly, the clinical manifestations, serological and immunological characteristics, as well as gastroscopic biopsy outcomes of the recruited patients with primary Sjogren's syndrome (pSS) were reported. The multivariable analysis of the dry syndrome patients infected with H. pylori displayed hypergammaglobulinemia (odds ratio [OR], 0.354; 95% confidence interval [CI], 0.189‐0.663), total cholesterol (OR, 1.158; 95% CI, 0.856‐1.550), hypertension (OR, 0.227; 95% CI, 0.114‐0.455), Female sex (OR, 5.778; 95% CI, 1.458‐22.9), anti‐SSA/Ro60 positive (OR, 2.384; 95% CI, 1.233‐4.645), γ‐GT (OR, 0.99; 95% CI, 0.99‐1.00) and alkaline phosphatase (OR, 1.00; 95% CI, 0.99–1.00) levels.ConclusionTogether, our findings demonstrated that hypergammaglobulinemia could be the independent risk factors of H. pylori infection in patients with Sjogren's syndrome, requiring the physician's advice in the future.

Published: October 2023

AbstractBiomaterials with nanoscale topography have been increasingly investigated for medical device applications to improve tissue–material interactions. This study assessed the impact of nanoengineered titanium surface domain sizes on early biological responses that can significantly affect tissue interactions. Nanostructured titanium coatings with distinct nanoscale surface roughness were deposited on quartz crystal microbalance with dissipation (QCM‐D) sensors by physical vapor deposition. Physico‐chemical characterization was conducted to assess nanoscale surface roughness, nano‐topographical morphology, wettability, and atomic composition. The results demonstrated increased projected surface area and hydrophilicity with increasing nanoscale surface roughness. The adsorption properties of albumin and fibrinogen, two major plasma proteins that readily encounter implanted surfaces, on the nanostructured surfaces were measured using QCM‐D. Significant differences in the amounts and viscoelastic properties of adsorbed proteins were observed, dependent on the surface roughness, protein type, protein concentration, and protein binding affinity. The impact of protein adsorption on subsequent biological responses was also examined using qualitative and quantitative in vitro evaluation of human platelet adhesion, aggregation, and activation. Qualitative platelet morphology assessment indicated increased platelet activation/aggregation on titanium surfaces with increased roughness. These data suggest that nanoscale differences in titanium surface roughness influence biological responses that may affect implant integration.
