Authors: Chen Junchao , Che Zhenglu , Gao Meiben , Zhang Liang , Shen Zhonghui 
Published: August 2024

AbstractIn true triaxial compression tests, all three principal stresses are imposed independently. This allows for a more comprehensive analysis of the material's mechanical properties. The end effect in true triaxial compression tests is a crucial phenomenon that impacts the accuracy and reliability of the test results. In this study, a series of true triaxial compression tests is conducted to examine the influence of the end friction on the mechanical properties. The laboratory results show that the presence of the end friction could bring about an apparent increase in rock strength and also restrict the deformation in each direction showing that the stiffness (the slope of the curves) increased slightly. The rock strength could be enhanced from 24.7 to 90.7 () when the end friction is increased, which is mainly caused by the lateral interface friction. The failure mode and fracture angle of the specimen are also influenced by the end effect, showing that under high friction conditions, the failure is more ductile, and a larger fracture angle is observed. At last, in comparison with the published experimental data, the actual specific friction angle (corresponding friction coefficient is about 0.19) for the direct specimen–metal contacts in a true 3D test is numerically identified, which is empirically reasonable and higher than the tested range 0.146–0.157 obtained from double‐shear test system.

Authors: Wang Zeyue , Pan Luwei , Lu Hao , Dai Fangqin 
Published: August 2024

AbstractThe effect of particle packing height (10, 30, 50, 70 mm) on the yield and composition of oil shale pyrolysis products is investigated. The results show that the oil yield could decrease 1.0% and the noncondensable gases yield could increase 0.5% as the oil shale packing height increased from 10 to 70 mm. The main hydrocarbon gases are C1–C6 gases, and the increase of packing bed height could decrease the relative content ratio of alkanes to alkenes in hydrocarbon gases. The primary components of the derived oil are aliphatic compounds, aromatic compounds, and compounds containing heteroatoms in the carbon atoms range of C6–C28. And the hydrogen type of shale oil is mainly composed of methylene groups (about 70%) with longer alkyl chains, and CH3 in aromatics, cycloalkanes, and alkanes. The chemical composition and hydrogen type have certain regularity changes with the changing of packing height, attributing to the effect of temperature gradients between surface and center of packing bed, and the diffusing time of products through the packing bed.

Published: August 2024

AbstractFinding an accessible parking spot using 5G technology can be considered as time and fuel expenses. In this manner, it might make drivers disappointed in the parking zone. This will prompt awful traffic around the parking spot and may likewise prompt a mishap. That is the reason this task proposes a Smart Parking framework that utilizes cameras which will be associated with a Raspberry Pi and it will likewise have an Android application as an interface to help book or view accessible spaces. E Parking framework for security empowerment in 5G can be characterized as the utilization of trend setting innovations for the effective activity, checking, and the board of parking inside an urban versatility technique. This task will help tackle issues referenced by permitting clients to see and select accessible space in the parking, which will keep clients from driving around. You Only Look Once (YOLO) algorithm, Adaptive Background Learning and also pre‐trained Mask‐RCNN are used for finding the nearest free parking slot. Currently, Raspberry Pi will be utilized as the connection between the Cameras and the Server, by moving information gathered from the Raspberry Pi to an online server in order to process the information and empower the Android application to get outcome. In an end, this venture will help in decreasing the measure of time a driver needs to spend around the parking just to locate an accessible spot, lessening the measure of traffic, diminishing contamination, expanding the security using 5G technologies and furthermore better monetizing the parking spot. The proposed system detects vehicles in indoor as well as outdoor parking fields accurately.

Heterogeneous autoregressions in short T panel data models
Authors: Pesaran M. Hashem , Yang Liying 
Published: August 2024

SummaryThis paper considers a first‐order autoregressive (AR) panel data model with individual‐specific effects and heterogeneous AR coefficients defined on the interval
, thus allowing for some of the individual processes to have unit roots. It proposes estimators for the moments of the cross‐sectional distribution of the AR coefficients, assuming a random coefficient model for the AR coefficients without imposing any restrictions on the fixed effects. It is shown that the standard generalized method of moments estimators obtained under homogeneous slopes are biased. Small sample properties of the proposed estimators are investigated by Monte Carlo experiments and compared with a number of alternatives, both under homogeneous and heterogeneous slopes. It is found that a simple moment estimator of the mean of heterogeneous AR coefficients performs very well even for moderate sample sizes, but to reliably estimate the variance of AR coefficients, much larger samples are required. It is also required that the true value of this variance is not too close to zero. The utility of the heterogeneous approach is illustrated in the context of earnings dynamics.

AbstractThe present study unveils the intricate details on the morphology of thrips through optical, field emission scanning electron microscopy (FE‐SEM) and mitochondrial cytochrome oxidase I gene‐based molecular identification tools. The variation in the morphological characters namely, antennae (seven‐segmented with forked sensorium on third, fourth segments), ctenidia (paired ctenidia were present in 5th–8th abdominal segments laterally), pronotum (two pairs of posteroangular setae) were observed in both Thrips tabaci and Thrips parvispinus, respectively. Similarly, ocelli color (brown and red colored), ocellar setae (two and three pairs of ocellar setae on the head of T. tabaci and T. parvispinus, respectively. Irregular reticulate striations on metascutum and medial striations are present in the metanotum of T. parvispinus; forewings with 6 distal setae in the first vein and 15 distal setae in the second vein in T. tabaci and forewings of T. parvispinus with complete rows of setae in the first and second vein in T. parvispinus; abdomen with median dorsal setae present in the tergite of T. tabaci and presence of 6–12 discal setae in sternites III–VI segments, absence of discal setae on sternites II and VII in T. parvispinus were observed, respectively. Further, FE‐SEM studies revealed that similar type of sensilla namely, sensilla basiconica (SBI, SBII, SBIII), sensilla chaetica (SChI, SChII), sensilla trichodea (ST), sensilla campaniformia (SCa), and sensilla cavity (SCav) were recorded in both the species and variations were observed in length of above sensilla of T. tabaci and T. parvispinus. Additionally, Bohm bristles (Bb) and microtrichia (Mt) on the antennal surface contributed to a comprehensive understanding of their ultrastructural features. The molecular characterization revealed a single ~450 bp nucleotide fragment with over 98% similarity for the confirmation of T. tabaci and T. parvispinus in concurrence with NCBI data.Research Highlights

Published: August 2024

AbstractFibraurea tinctoria Lour. (Menispermaceae) is a medicinal plant used by many local tribes in Indonesia and other countries. This species has pharmacological potential, such as antimalaria, antibacterial, antitumor, antioxidant, anticancer, antidiabetic, anti‐inflammatory, and hepato‐protector. However, the secretory structures and sites of secondary metabolite accumulation still need to be studied. This study aimed to explore the secretory structures and reveal the accumulation sites of the main classes of secondary metabolites in the root, stem, and leaves of F. tinctoria. Histochemical analysis using various specific reagents was performed on freehand sections of the fresh organs to detect alkaloids, phenolics, terpenoids, and lipophilic compounds. Observations of secretory structures were carried out using light microscopy. The result showed that idioblast was the predominant secretory structure in the plant organs and contained all the chemical groups investigated, while laticifer accumulated alkaloids were found only in the stem. Some secondary metabolites were localized in the xylem, intercellular space, and cuticle layer. Crystals were observed in the root, stem, and leaf of this species. These results might be helpful as guide information for extracting the particular plant parts to obtain the desired secondary metabolites. It suggested that leaves are a potential alternative source of medicinal raw material of this species, in addition to the stem.Research Highlights
The first study on secretory structures of Fibraurea tinctoria.
Secondary metabolites in F. tinctoria organs accumulate in specialized and unspecialized structures.
The idioblast is the primary secretory structure in the organs of F. tinctoria spreading over the root, stem, and leaves.

AbstractBackground/PurposeA recent study has demonstrated that the timing of endoscopic ultrasound‐guided fine needle aspiration (EUS‐FNA) significantly influences the peritoneal lavage cytology (CY) outcomes in pancreatic body‐tail cancer. The aim of this study was to clarify the impact of EUS‐FNA on CY positivity in patients with resectable pancreatic body‐tail cancer.MethodsPatients with anatomically resectable pancreatic body‐tail cancer surgically resected at Hiroshima University Hospital were enrolled, and elated clinicopathological factors, including EUS‐FNA variables and CY positivity rate, were analyzed.ResultsOf the 129 eligible patients, 16 (12%) had positive CY. The EUS‐FNA rates of the CY‐positive and CY‐negative groups were not significantly different (63% vs. 52%, p = .440). Multivariate analysis revealed that lymph node metastasis was the only independent risk factor for CY positivity (odds ratio: 5.734, p = .031). A total of 10 (14%) of the 69 patients who underwent EUS‐FNA had positive CY; however, needle specifications and the interval between EUS‐FNA and CY examination did not differ between the CY‐positive and CY‐negative groups. CY positivity rates were comparable for intervals ≤14 days and ≥15 days (17% vs. 14%, p = 1.000).ConclusionsEUS‐FNA may not affect CY positivity in patients with resectable pancreatic body‐tail cancer, regardless of the timing.

ABSTRACTThis research presents the development of positron emission tomography (PET) radiotracers for detecting Mycobacterium tuberculosis (MTB) for the diagnosis and monitoring of tuberculosis. Two phage display–derived peptides with proven selective binding to MTB were identified for development into PET radiopharmaceuticals: H8 (linear peptide) and PH1 (cyclic peptide). We sought to functionalize H8/PH1 with NODASA, a bifunctional chelator that allows complexation of PET‐compatible radiometals such as gallium‐68. Herein, we report on the chelator functionalization, optimized radiosynthesis, and assessment of the radiopharmaceutical properties of [68Ga]Ga‐NODASA‐H8 and [68Ga]Ga‐NODASA‐PH1. Robust radiolabeling was achieved using the established routine method, indicating consistent production of a radiochemically pure product (RCP ≥ 99.6%). For respective [68Ga]Ga‐NODASA‐H8 and [68Ga]Ga‐NODASA‐PH1, relatively high levels of decay‐corrected radiochemical yield (91.2% ± 2.3%, 86.7% ± 4.0%) and apparent molar activity (Am, 3.9 ± 0.8 and 34.0 ± 5.3 GBq/μmol) were reliably achieved within 42 min, suitable for imaging purposes. Notably, [68Ga]Ga‐NODASA‐PH1 remained stable in blood plasma for up to 2 h, while [68Ga]Ga‐NODASA‐H8 degraded within 30 min. For both 68Ga peptides, minimal whole‐blood cell binding and plasma protein binding were observed, indicating a favorable pharmaceutical behavior. [68Ga]Ga‐NODASA‐PH1 is a promising candidate for further in vitro/in vivo evaluation as a tuberculosis‐specific infection imaging agent.

Published: August 2024

AbstractHemorrhagic fever with renal syndrome (HFRS) and severe fever with thrombocytopenia syndrome (SFTS) are both endemic in rural areas and some characteristics are similar between HFRS and SFTS, which usually lead to misdiagnosis. In this study, we summarized and compared some characteristics of HFRS and SFTS which will provide scientific information for differential diagnosis. From 2011 to 2022, a total of 4336 HFRS cases and 737 SFTS cases were reported in Zhejiang Province. Compared to SFTS, there was a higher proportion of males among HFRS cases (72.46% [3142/4336] vs. 50.88% [375/737], p = 0.000). The median age of all 4336 HFRS cases was 49 (39, 59), while the median age of SFTS cases was 66 (57, 74). In addition, the involved counties of HFRS were more than SFTS, but the number of counties affected by SFTS increased from 2011 to 2022. The majority of SFTS cases occurred in summer (from May to July), but besides summer, HFRS cases also showed a peak in winter. Finally, our results showed that the case fatality rate of SFTS was significantly higher than that of HFRS. Although there were some similarities between HFRS and SFTS, our study found several differences between them, such as gender distribution, age distribution, and seasonal distribution, which will provide scientific information for differential diagnosis of HFRS and SFTS. Further studies should be carried out to explore the mechanism of these differences.
Consumers’ purchase intention of private labels: The case of e‐retailers
Authors: Yadav Sher Singh , Kar Sanjay Kumar 
Published: August 2024

AbstractIn economically vulnerable situations such as the pandemic, private‐label products generate bigger appeal. The behavior of online private‐label consumers has remained understudied thus far, despite several studies suggesting that different channels lead to different consumer behaviors. This study aims to develop and test a theoretical model that elucidates the factors influencing the online purchase intention of private‐label products in a post‐pandemic scenario. We assess the role of attitude in the relationship between value consciousness, convenience, perceived quality, awareness, price consciousness, private‐label image, retailer reputation, and functional risk, in relation to purchase intention. The study is based on a sample of 318 respondents and employs variance‐based partial least squares structural equation modeling (PLS‐SEM) for data analysis using Smart PLS 3. This study is one of the first to delve into post‐pandemic research on online private‐label products during an economic downturn. This study explores the purchase intention toward online private‐label products by drawing on the theory of planned behavior, attribution theory, and cue utilization theory. Our results reveal that retailer reputation influences private‐label image, which affects purchase intention. Additionally, perceived quality, private‐label image, and attitude positively influence the purchase intention of private‐label products. Retailer reputation also affects private‐label image and value consciousness. Furthermore, convenience has a positive effect on attitudes toward the online purchase of private labels. Interestingly, price consciousness did not affect the purchase intention of online private labels. These findings have significant implications for private‐label online retailers and policymakers. This article extends the current private‐label theory and holds promise for future application in an omnichannel private‐label context.

Published: August 2024

AbstractObjectivesThe gut microbiota plays an important role in childhood growth. Our longitudinal cohort includes children with cystic fibrosis (CwCF) treated with highly effective modulator therapy. We aimed to elucidate early premodulator microbial signatures associated with postmodulator weight for CwCF later in childhood.MethodsStool samples were collected from CwCF at 13 days to 60 months. Metagenomic sequencing determined differentially abundant taxa. Children with body mass index or weight for length Z‐scores within 1 standard deviation of the mean (SD) were considered normal weight, those >1 SD were classified as risk of overweight while children <1 SD were considered undernourished, although no CwCF met this latter criterion here. Multivariate regression models were applied to identify significant associations between metadata and microbial taxonomic relative abundances.ResultsOne hundred and eighty‐nine stool samples were analyzed from 39 CwCF. We identified statistically significant differences in early microbiome patterns among those at risk of being overweight compared to those who were normal weight when adjusted for age, sex, CF mutation, and early feeding method. Early microbiome was a stronger driver of growth status than current modulator use. Among those at risk of overweight, several taxa that were consistently in lower abundance included Eggerthella lentha, Ruminococcus, Bacteroides, with increase in abundance of Bacteroides stercoris.ConclusionsThe early microbiome strongly predicts growth in the setting of modulator use for CwCF and we identify microbiome signatures associated with risk of being overweight. We highlight the possibility for interventions or early alternations to nutritional guidance for prevention of comorbid complications.

Published: August 2024

ABSTRACTImmersive experiences offered by virtual reality (VR) have the power to impact tourists' decision‐making and on‐site experiences. However, prior research has focused on explaining VR's acceptance by tourists as a function of technological capacity, rather than user characteristics, such as innovativeness. This research intends to fill the existing knowledge gap regarding the role of technological innovativeness on VR experiences. To do so, this study examines whether individuals' technological innovativeness influences their perceptions of a VR tourism experience and, in turn, their intention to recommend the experience. The study provides a VR experience to 405 tourists at a winery. The results reveal that the tourists' technological innovativeness influences their perception of enjoyment, experience quality, and satisfaction. These findings suggest that, when developing or distributing VR content, the technological innovativeness of the audience is important to consider. The findings have theoretical and practical value, with direct implications for tourism professionals and policymakers.

ObjectivesTo compare the efficacy of the 445‐nm blue laser to the 585‐nm pulsed dye laser (PDL) and 532‐nm potassium‐titanyl‐phosphate (KTP) laser in the treatment of benign laryngeal lesions.Data SourcesCochrane Library, PubMed, Scopus, and CINAHL.Review MethodsFollowing PRISMA guidelines, databases were searched from inception through January 29, 2024, for studies reporting the use of photoangiolytic lasers for treatment of benign laryngeal lesions, including the 585‐nm PDL, 532‐nm KTP laser, and 445‐nm blue laser. Outcome measures included lesion resolution (%), mean differences (Δ) in Voice Handicap Index (VHI‐10), and summed dysphonia grade, roughness, and breathiness (GRB) scale.ResultsA total of 45 studies were included for meta‐analysis, consisting of 348 patients treated with PDL, 550 patients with KTP laser, and 338 patients with blue laser. Treatment with blue laser resulted in the greatest lesion resolution (94.0%; 95% confidence interval [CI]: 90.2%–96.7%), followed by KTP laser (90.4%; 95% CI: 84.1%–95.2%), and PDL (86.9%; 95% CI: 62.9%–99.2%). VHI‐10 improved significantly in patients following treatment with blue laser (Δ13.3; 95% CI: 10.7–16.0; p < 0.0001), KTP laser (Δ10.3; 95% CI: 7.4–13.3; p < 0.0001), and PDL (Δ7.4; 95% CI: 4.8–10.1; p < 0.0001). GRB improved significantly in patients following treatment with blue laser (Δ4.1; 95% CI: 2.9–5.2; p < 0.0001), KTP laser (Δ3.0; 95% CI: 2.0–4.0; p < 0.0001), and PDL (Δ2.5; 95% CI: 0.8–4.2; p = 0.005).ConclusionsPhotoangiolytic lasers are effective in treating benign laryngeal lesions. Blue lasers are promising for laryngeal laser surgery. Laryngoscope, 134:4847–4857, 2024
