Patient influencer: the impact of homophily on value co-creation behaviour in online health communities

ABSTRACT The world has witnessed a rapid rise of online health communities (OHCs) where patients can create a powerful network of support and resources to make a meaningful difference in people’s health lives. Despite this rapid rise, healthcare authorities and organisations are under enormous pressure to create a sustainable environment for OHCs. Prior studies revealed that encouraging patient value co-creation behaviour (VCB) is substantially beneficial for successful OHCs; however, what factors influence these patient behaviours to co-create value is still unknown. To fill this gap, this study uses the service-dominant logic perspective of value co-creation theory and discloses how homophily between patient influencers and patients in OHCs effect VCB. The data was collected through a self-administered survey from 422 patients who are users of OHC in China and was analysed via partial least squares structural equation modelling and fuzzy set qualitative comparative analysis (fsQCA). The results revealed that homophily positively influences VCBs, i.e. participation behaviour (PB) and citizenship behaviour (CB). A parasocial relationship only moderates the relations between homophily and (PB), whereas the influencer ethical interaction capability significantly moderates the relationship of both homophily with patient PB and CB. Furthermore, the fsQCA findings signify the robustness of the study model.

Diet-omics in the Study of Urban and Rural Crohn disease Evolution (SOURCE) cohort

Crohn disease (CD) burden has increased with globalization/urbanization, and the rapid rise is attributed to environmental changes rather than genetic drift. The Study Of Urban and Rural CD Evolution (SOURCE, n = 380) has considered diet-omics domains simultaneously to detect complex interactions and identify potential beneficial and pathogenic factors linked with rural-urban transition and CD. We characterize exposures, diet, ileal transcriptomics, metabolomics, and microbiome in newly diagnosed CD patients and controls in rural and urban China and Israel. We show that time spent by rural residents in urban environments is linked with changes in gut microbial composition and metabolomics, which mirror those seen in CD. Ileal transcriptomics highlights personal metabolic and immune gene expression modules, that are directly linked to potential protective dietary exposures (coffee, manganese, vitamin D), fecal metabolites, and the microbiome. Bacteria-associated metabolites are primarily linked with host immune modules, whereas diet-linked metabolites are associated with host epithelial metabolic functions.

Roadmap on Perovskite light-emitting diodes

Abstract In recent years, the field of metal-halide perovskite emitters has rapidly emerged as a new community in solid-state lighting. Their exceptional optoelectronic properties have contributed to the rapid rise in external quantum efficiencies (EQEs) in perovskite light-emitting diodes (PeLEDs) from <1% (in 2014) to approaching 30% (in 2023) across a wide range of wavelengths. However, several challenges still hinder their commercialization, including the relatively low EQEs of blue/white devices, limited EQEs in large-area devices, poor device stability, as well as the toxicity of the easily accessible lead components and the solvents used in the synthesis and processing of PeLEDs. This roadmap addresses the current and future challenges in PeLEDs across fundamental and applied research areas, by sharing the community's perspectives. This work will provide the field with practical guidelines to advance PeLED development and facilitate more rapid commercialization.

Cannabis Legalization and Resource Use for Ingestions by Young Children.

In conjunction with widening legalization, there has been a rapid rise in unintentional cannabis ingestions in young children. We sought to determine if the legal status of recreational cannabis was associated with resource use in young children with cannabis poisoning. This retrospective cross-sectional study of the Pediatric Health Information System included emergency department encounters between January 2016 and April 2023 for children <6 years of age with a diagnosis indicating cannabis ingestion. The primary exposure was recreational cannabis legalization status in the state in which the encounter occurred. We used logistic regression models to determine the association of recreational cannabis legality with resource utilization outcomes, adjusting for demographic covariates. We included 3649 children from 47 hospitals; 29% of encounters occurred in places in which recreational cannabis was legal. Compared with environments in which recreational cannabis was illegal, cannabis-legal locations had lower uses of advanced neuroimaging (24% vs 35%; adjusted odds ratio [aOR], 0.65; 95% confidence interval [CI]: 0.55-0.77), lumbar puncture (1.6% vs 3.8%; aOR, 0.42; 95% CI: 0.24-0.70), ICU admission (7.9% vs 11%; aOR, 0.71; 95% CI: 0.54-0.93), and mechanical ventilation (0.8% vs 2.9%; aOR, 0.30; 95% CI: 0.14-0.58). Urine testing was more common in places in which recreational cannabis was legal (71% vs 58%; aOR, 1.87; 95% CI: 1.59-2.20). State-level legalization of recreational cannabis was associated with a significant decrease in the utilization of advanced medical resources in cases of cannabis intoxication in children. These findings suggest the need for a focus on policies and procedures to minimize invasive testing in cases of cannabis intoxication in children.

Pressure Changes Across a Membrane Formed by Coacervation of Oppositely Charged Polymer-Surfactant Systems.

We investigate the mass transfer and membrane growth processes during capsule formation by the interaction of the biopolymer xanthan gum with CnTAB surfactants. When a drop of xanthan gum polymer solution is added to the surfactant solution, a membrane is formed by coacervation. It encapsulates the polymer drop in the surfactant solution. The underlying mechanisms and dynamic processes during capsule formation are not yet understood in detail. Therefore, we characterized the polymer-surfactant complex formation during coacervation by measuring the surface tension and surface elasticity at the solution-air interface for different surfactant chain lengths and concentrations. The adsorption behavior of the mixed polymer-surfactant system at the solution-air interface supports the understanding of observed trends during the capsule formation. We further measured the change in capsule pressure over time and simultaneously imaged the membrane growth via confocal microscopy. The cross-linking and shrinkage during the membrane formation by coacervation leads to an increasing tensile stress in the elastic membrane, resulting in a rapid pressure rise. Afterward, the pressure gradually decreases and the capsule shrinks as water diffuses out. This is not only due to the initial capsule overpressure but also due to osmosis caused by the higher ionic strength of the surfactant solution outside the capsule compared to the polymer solution inside the capsule. The influence of polymer concentration and surfactant type and concentration on the pressure changes and the membrane structure are studied in this work, providing detailed insights into the dynamic membrane formation process by coacervation. This knowledge can be used to produce capsules with tailored membrane properties and to develop a suitable encapsulation protocol in technological applications. The obtained insights into the mass transfer of water across the capsule membrane are important for future usage in separation techniques and the food industry and allow us to better predict the capsule time stability.

Aluminium Scandium Nitride Thin Film BAW Resonators (FBAR) for 5G Applications

With the growing impact of 5G communication system, Radio-Frequency Micro-Electro-Mechanical-Systems (RF MEMS) technologies are becoming increasingly important in our daily lives. Development of filters in the 5G frequency range is being carried out tremendously. The rapid rise in smartphone usage, heightened data demands, congestion in the frequency spectrum, and advancements in technology have posed numerous challenges for the development of RF filters. The ultimate goal is to simplify the RF Front End Module used in smart phones, thereby achieving better selectivity. In this paper, a high frequency - high Q thin film bulk acoustic wave resonator of piezoelectric material Aluminium scandium nitride (AlScN)based FBAR is designed for 5G Application. Finite element analysis conducted using the COMSOL Multiphysics software assess the characteristics of the constructed FBAR. The outcomes indicate that the device resonates effectively at 5 GHz, exhibiting commendable return loss and a Q-factor of 1490. A high-resonance-frequency FBAR device offers advantages for 5G mobile technology.

Money Supply, Inflation and Dollarization: An Analysis on Türkiye Using Fourier Models

This study examines the impact of inflation and money supply on dollarization. Especially in recent years, the rapid rise of the exchange rate and inflation in Türkiye has put the phenomenon of dollarization back on the agenda. The study covers the period 2012Q4-2023Q4. The study first applies the Fourier ADL cointegration test, which allows for soft breaks. As a result of the test, it was found that the variables have a long run relationship. In the short run, only budget revenue has a positive effect on dollarization. In the long run, the exchange rate, exports, money supply, and deposit rates have a positive effect, while inflation has a negative effect. The study also applied the Fourier-Toda-Yamamoto causality test. As a result of the test, bidirectional causality was found between exchange rate, inflation and money supply variables and dollarization. The striking result of the study is that inflation has a negative impact on dollarization. This result, which is consistent with some studies in the literature, is attributed to the money supply. Although the demand for foreign exchange increases because the money supply is higher than inflation, the dollarization index decreases. This explanation can explain the negative relationship.

Assessment of stereotactic high-resolution detectors for stereotactic body radiotherapy: comparative analysis between myQA® SRS and Gafchromic EBT-XD films.

The study aimed to evaluate dosimetry systems used for stereotactic body radiotherapy (SBRT), specifically 2D array dosimetry and film dosimetry systems, for exploring their characteristics and clinical suitability. For this, high-resolution myQA SRS detectors and Gafchromic EBT-XD films were employed. Film analysis included net optical density (OD) values depending on energy, dose rate, scanner orientation, scanning side, and post-exposure growth. For myQA SRS, signal values were evaluated in terms of dose rate (400-1400 MU/min) and angular dependence (0-180° at 30° intervals) along with couch angles of 0°, 45°, and 90°. Pre-treatment verification included 32 SBRT patients for whom myQA SRS results were compared with those obtained with Gafchromic EBT-XD films. Analysis revealed less than 1% deviation in net OD for energy and dose rate dependence. Scanner orientation caused 2.5% net OD variation, with minimal differences between film front and back scan orientations (variance < 1.0%). A rapid OD rise occurred within six hours post-exposure, followed by gradual increase. The myQA SRS detector showed -3.7% dose rate dependence (400 MU/min), while the angular dependence at 90° was -26.7%. A correction factor effectively reduced these differences to < 1%. For myQA SRS, gamma passing rates were-93.6% (2%/1mm), while those for EBT-XD films were-92.8%. Improved rates were observed with 3%/1mm: for myQA SRS-97.9%, and for EBT-XD film-98.16%. In contrast, for 2%/2mm with 10% threshold, for myQA SRS-97.7% and for EBT-XD film-98.97% were obtained. It is concluded that both myQA SRS detectors and EBT-XD films are suitable for SBRT pre-treatment verification, ensuring accuracy and reliability. However, myQA SRS detectors are preferred over EBT-XD film due to the fact that they offer real-time measurements and user-friendly features.

Experimental investigation on the effect of diesel-ethanol blends for a constant-speed diesel engine

ABSTRACT Keeping the need for energy security and the world’s transition to a thriving low-carbon economy in mind, the research, on the feasibility of diesel ethanol blends, has gained momentum. The present work is related to comparing the performance and emission characteristics of pure diesel [D100] with 4 diesel-ethanol blends [D90E10, D85E15, D80E20 and D75E25]. The single-cylinder 4-stroke un-modified diesel engine running at constant 1500 rpm was used for experimentation which ran at different loads. Experimental results showed that with the addition of ethanol in blends, the brake thermal efficiency (BTE) and exhaust gas temperature (EGT) reduced while brake-specific fuel consumption (BSFC) increased. The addition of ethanol shortened the combustion duration. Hence, D75E25 showed a rapid rise in combustion pressure and heat release rate (HRR). As the concentration of ethanol increases in blends, the oxide of nitrogen (NOx) is reduced and carbon monoxide and hydrocarbon (HC) are increased. Thus, D75E5 was good blend producing less NOx with the penalty of fuel consumption on an unmodified diesel engine. In the long run, the effect of blends on the engine should be checked to make ethanol a feasible fuel for diesel engines.

Experimental Evaluation of an SDR-Based UAV Localization System

UAV communications have seen a rapid rise in the last few years. The drone class of UAV has particularly become more widespread around the world, and illicit behavior using drones has become a problem. Therefore, localization, tracking, and even taking control of drones have also gained interest. Knowing the frequency of a target signal, its position can be determined (as the angle of arrival with respect to a fixed receiver point) using radio frequency-based localization techniques. One such technique is represented by the subspace-based algorithms that offer highly accurate results. This paper presents the implementation of the MUSIC algorithm on an SDR-based system using a uniform circular antenna array and its experimental evaluation in relevant outdoor environments for drone localization. The results show the capability of the system to indicate the AoA of the target signal. The results are compared with the actual direction computed from the log files of the drone application and validated with a professional direction-finding solution (i.e., Narda SignalShark equipped with the automatic direction-finding antenna).

A bibliometric analysis of research trends on the microbiological safety of lowmoisture foods

Research has shown that some pathogens, including Salmonella and other spore-formers, survive and remain viable in low-moisture foods (LMF). This review highlighted trends in publication and outlook of the research field, using articles published in Scopus between 2001 to 2020. Systematic article retrieval, data analysis, and trend visualization were conducted using Scopus analytical tools, Excel software, and VOSviewer, respectively. A total of 267 articles were published on the microbial safety of LMF, with a rapid rise in the number of publications per year. The U.S. has the highest research output (143 publications), followed by China (35 publications). Washington State University Pullman, USA, has the highest number of publications from a single institution, while Professor Juming Tang is the author with the highest number of publications. Evaluation of trends in LMF research highlighted an initial focus on the detection of possible microbial contaminants in the foods and exploring the relationship between water activity and microbial survival. Salmonella was identified as the leading cause of foodborne diseases associated with the consumption of LMF. Newer research is focusing on the molecular characterization of microbial contaminants of LMF and approaches to eliminate these pathogens and spoilage agents from LMF. In recent years, the trend has shifted towards the use of novel technologies for microbial and toxin inactivation to mitigate and minimize the risks due to the presence of these microbial agents and their metabolites in LMF.

Post-glacial small delta process uncovered by luminescence and radiocarbon chronology of core sediments from coastal South China Sea

Reliable chronology is crucial for reconstructing delta processes. The past decades witnessed a boost of dating works on the most economically influential large deltas (i.e., subaerial area >1000 km2), but chronology remains lacking on many small deltas (i.e., subaerial area <1000 km2) that are also densely populated and economically active. Luohe River Delta (LRD) in the coastal South China Sea is such a small delta, whose evolution concerns hundreds of thousands of people, and literally no reliable dating results have been reported to support research of its processes. Herein, dating work combining radiocarbon (14C) on mollusk shells and quartz Optically Stimulated Luminescence (OSL) methods were performed on core LFZK06 from LRD, to test applicability of both methods by age comparison and to establish a chronological framework, using Bayesian age-depth models, of LRD for the first time. 14C ages are systematically c. 0.5–1 ka younger than OSL ages from the same depths. Such young bias of 14C ages in LRD contrasts with previously observed overestimated 14C results in the nearby Pearl River Delta (PRD), likely due to the distinction in bedrock types between Luohe River (granites and sandstones only) and Pearl River (limestone prevalence causing hardwater effect) drainages. Ages of core LFZK06 span from 57 ± 7 ka to 3.42 ± 0.05 cal ka BP and contain a hiatus between 57±7–11.9 ± 1.7 ka. Holocene deltaic sequence of the core shows three-stage sedimentary processes: (1) rapid deposition of prodelta/delta front sediments at 10.2‐0.4+0.5 ka–7.7‐0.3+0.4 ka related to rapid sea level rise, (2) hiatus during 7.7‐0.3+0.4 ka–5.7‐0.8+0.5 ka likely due to reduced sediments input or river channel migration, (3) rapid accumulation of delta plain sediments during 5.7‐0.8+0.5 ka–3.42‐0.85+0.42 ka reflecting depocenter shift toward core location. Moreover, changes of quartz OSL sensitivity were detected, indicative of sediment provenance transition. A change in sediment source from nearby granite weathering towards fluvial long-transported materials occurred at a depth of 24.7 m, with low quartz OSL sensitivity in the gravelly layer below (11.9 ± 1.7 ka) and one magnitude higher quartz OSL sensitivity in prodelta deposits above (10.2‐0.4+0.5 ka).

Discovery and follow-up of ASASSN-23bd (AT 2023clx): The lowest redshift and luminosity optically-selected tidal disruption event

Abstract We report the All-Sky Automated Survey for SuperNovae discovery of the tidal disruption event (TDE) ASASSN-23bd (AT 2023clx) in NGC 3799, a LINER galaxy with no evidence of strong AGN activity over the past decade. With a redshift of z = 0.01107 and a peak UV/optical luminosity of (5.4 ± 0.4) × 1042 erg s−1, ASASSN-23bd is the lowest-redshift and least-luminous TDE discovered to date. Spectroscopically, ASASSN-23bd shows Hα and He i emission throughout its spectral time series, there are no coronal lines in its NIR spectrum, and the UV spectrum shows nitrogen lines without the strong carbon and magnesium lines typically seen for AGN. Fits to the rising ASAS-SN light curve show that ASASSN-23bd started to brighten on MJD 59988$^{+1}_{-1}$, ∼9 days before discovery, with a nearly linear rise in flux, peaking in the g band on MJD $60000^{+3}_{-3}$. Scaling relations and TDE light curve modelling find a black hole mass of ∼106  M⊙, which is on the lower end of supermassive black hole masses. ASASSN-23bd is a dim X-ray source, with an upper limit of L0.3 − 10 keV &amp;lt; 1.0 × 1040 erg s−1 from stacking all Swift observations prior to MJD 60061, but with soft (∼0.1 keV) thermal emission with a luminosity of L0.3 − 2 keV ∼ 4 × 1039 erg s−1 in XMM-Newton observations on MJD 60095. The rapid (t &amp;lt; 15 days) light curve rise, low UV/optical luminosity, and a luminosity decline over 40 days of ΔL40 ≈ −0.7 dex make ASASSN-23bd one of the dimmest TDEs to date and a member of the growing ‘Low Luminosity and Fast’ class of TDEs.

The Impact of the Rural Digital Economy on Agricultural Green Development and Its Mechanism: Empirical Evidence from China

Agricultural green development represents an environmentally friendly and resource-efficient agricultural model, and it is a key way to achieve sustainable agricultural development. With the rapid rise of the digital economy, its influence is gradually spreading from urban to rural areas, and it has played a significant and far-reaching role in promoting the green transformation of agriculture. This paper employs the entropy weight method to measure the level of digital economy and agricultural green development in rural areas in 30 provincial administrative regions in China from 2012 to 2021 and analyzes the relationship between the two and the mechanisms behind it. The research results show that (1) the rural digital economy significantly promotes agricultural green development. (2) With the enhancement of agricultural green development, the impact of the rural digital economy on it initially increases and then declines. (3) The rural digital economy fosters agricultural green development by advancing agricultural technology, easing credit constraints, and promoting agricultural industry agglomeration. (4) Environmental regulation intensifies the positive influence of the rural digital economy on agricultural green development. This research significantly enhances our understanding of the mechanism by which the rural digital economy facilitates agricultural green development. It offers empirical evidence and recommendations for the government to formulate and implement effective policies to advance agricultural green transformation in the context of digital economy trends.

A review of common methods used in the analysis of human microbiome sequencing data

The past two decades have seen a rapid rise in the development and use of sequencing technologies. The advent of high-throughput sequencing (HTS) has allowed scientists sequence the genomic content of entire microbial communities rapidly and affordably. Methods for data management, visualization, and analysis of this microbiome sequencing data are now widespread in open and closed source software tools. In this review, we identify common analysis methods used in microbiome sequencing studies, including methods for normalisation of abundance table data, visualization of high-dimensional microbiome data and the analysis of longitudinal microbiome sequencing data. In particular we find that a very small proportion of metagenomic studies made use of compositional data analysis methods and none that made use of compositional methods for longitudinal microbiome data.

Long-Acting Gonadotropin-Releasing Hormone Analogues for Central Precocious Puberty, Including 45-mg 6-month Subcutaneous Leuprolide Acetate: Use for Treatment and Treatment Monitoring.

Studies of gonadotropin-releasing hormone analogues [intramuscular (IM) leuprolide acetate (LA) and triptorelin] for treatment monitoring of central precocious puberty (CPP) demonstrate this approach is effective for confirming pubertal hormone suppression. Herein, we provide new data using subcutaneous LA (SC LA) suggesting similar efficacy for treatment monitoring. PubMed, Embase, and CINAHL were searched for studies of GnRHa use to monitor treatment of CPP. The titles and the abstracts were reviewed; five studies were selected. Additionally, new unpublished data for SC LA from the original phase 3 trial (primary data published by Klein et al.) were evaluated. Serum LH and leuprolide levels at screening, 1, 4, and 6 hours after the first dose SC LA were analyzed and plotted. Data from 162 children (155 girls) were evaluated. SC and IM LA produced overlapping median LH concentration curves and peak LH concentrations after the first dose. For IM LA, subsequent doses yielded suppressed peak LH levels (2.7 IU/L [mean]). For SC LA, subsequent doses also resulted in significant suppressed peak LH levels (0.2±0.02 IU/L) and achieved sex-steroid hormone suppression in &gt;98%. Compared to IM LA and triptorelin, long-acting SC LA shows similar burst kinetics and rapid LH rise after the first dose, followed by similar suppression of LH and sex steroids after subsequent doses. Since IM LA and triptorelin have demonstrated usefulness that is comparable to that of traditional GnRH stimulation testing for monitoring CPP, we presume that SC LA may be similarly employed.

Deglacial Carbon Escape From the Northern Rim of the Southern Ocean

AbstractThe Southern Ocean regulates atmospheric CO2 and Earth's climate as a critical region for air‐sea gas exchange, delicately poised between being a CO2 source and sink. Here, we estimate how long a water mass has remained isolated from the atmosphere and utilize 14C/12C ratios (Δ14C) to trace the pathway and escape route of carbon sequestered in the deep ocean through the mixed layer to the atmosphere. The position of our core at the northern margin of the Southern Indian Ocean, tracks latitudinal shifts of the Southern Ocean frontal zones across the deglaciation. Our results suggest an expanded glacial Antarctic region trapped CO2, whereas deglacial expansion of the subantarctic permitted ventilation of the trapped CO2, contributing to a rapid atmospheric CO2 rise. We identify frontal positions as a key factor balancing CO2 outgassing versus sequestration in a region currently responsible for nearly half of global ocean CO2 uptake.

Analysis of the population density trend of the finless porpoise based on smart IoT technologies

AbstractWith the rapid expansion of human activities, natural environmental systems are under severe threat. Yangtze River, the largest river in China, contains abundant biological resources. However, the ecosystem of the Yangtze River has been threatened by the rapid rise of human activities due to economic development in the 1990s. The Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis is a critically endangered flagship species in the Yangtze River. Although scientists have conducted surveys studying the abundance of Yangtze finless porpoise, the length of the investigation period of these studies was restricted. Here, we reported our meta-analysis results by collecting data on the abundance of the Yangtze finless porpoise population from published papers over 33 years. We found that the pooled effect size using the random effect model across all these studies was – 0.36 (95% confident interval (CI) – 0.48,– 0.24, P &lt; 0.05), indicating that the porpoise population has undergone a declining pattern after the year 2003. The operation of the Three Gorges Dam was one important but not the only factor resulting in the decline of the porpoise population. More actions should be taken for porpoise and habitat protection and more studies should be done to assess the impact of dams on the porpoise population in Poyang Lake. Only in this way can marine life be better protected, and the marine environment can better achieve sustainable development.

A marine incursion during the onset of T-OAE in Sichuan Basin, China: Evidence from green clay minerals and carbonate concretions

A high-amplitude global sea level rose rapidly during the early Toarcian (Early Jurassic), making the transgression deposits potential stratigraphic correlation markers of marine and terrestrial successions. Green clay minerals (i.e., glauconite and chamosite), carbonate concretions, and geochemical database associated with the early Toarcian global transgression are archived in the Lower Jurassic Da'anzhai Member (the Early Toarcian age) in the Sichuan Basin of China, a mega lake along the Tethys Ocean. The fine-grained glauconites with high Al and low Si contents suggested that they were transported from offshore to the lake by marine incursion and were oxidized during the transport processes. The green authigenic chamosite cement and redeposited chamosite grains with high Mg/Fe and low Al/Si ratios were diagenetically transformed from berthierine formed in the brackish water caused by marine incursion. The chemically impure siderite concretions with low 87Sr/86Sr ratios and high δ13C values suggested that the lake water and sediment pore waters were mixed with seawater. Coeval calcareous concretions have low 87Sr/86Sr ratios and high δ13C values, indicating the mixing of lake water with seawater. Combining the stratigraphic low 87Sr/86Sr values, we suggested that there was a marine incursion into the Sichuan Basin. According to the organic carbon isotopic stratigraphy correlation, the marine incursion occurred during the onset of T-OAE. The rapid and high-amplitude global sea-level rise may have caused this marine incursion.
