Published: January 2023

Conifer (Pinaceae) needles are the most frost‐hardy leaves. During needle freezing, the exceptional leaf anatomy, where an endodermis separates the mesophyll from the vascular tissue, could have consequences for ice management and photosynthesis. The eco‐physiological importance of needle freezing behaviour was evaluated based on the measured natural freezing strain at the alpine treeline. Ice localisation and cellular responses to ice were investigated in mountain pine needles by cryo‐microscopic techniques. Their consequences for photosynthetic activity were assessed by gas exchange measurements. The freezing response was related to the microchemistry of cell walls investigated by Raman microscopy. In frozen needles, ice was confined to the central vascular cylinder bordered by the endodermis. The endodermal cell walls were lignified. In the ice‐free mesophyll, cells showed no freeze‐dehydration and were found photosynthetically active. Mesophyll cells had lignified tangential cell walls, which adds rigidity. Ice barriers in mountain pine needles seem to be realised by a specific lignification patterning of cell walls. This, additionally, impedes freeze‐dehydration of mesophyll cells and enables gas exchange of frozen needles. At the treeline, where freezing is a dominant environmental factor, the elaborate needle freezing pattern appears of ecological importance.
Legislative Intentions and Counterfactu‐als: Or, What One Can Still Learn from Dworkin's Critique of Legal Positivism
Authors: Canale Damiano , Tuzet Giovanni
Published: January 2023

Riggs v. Palmerhas become famous since Dworkin used it to show that legal positivism is defective. The debate over the merits of Dworkin's claims is still very lively. Yet not enough attention has been paid to the fact that the content of the statute at issue inRiggswas given by thecounterfactual intentionof the legislature. According to arguments from legislative intent, a judicial decision is justified if it is based on the lawmaker's intention. But can legislative intentions be determined counterfactually? More generally, what are the discursive commitments undertaken by a lawyer or a judge, in an exchange of legal reasons, when using this interpretive methodology? This paper addresses these issues considering, in particular, David Lewis's “resemblance” condition and “relevant similarity” between possible worlds in the evaluation of counterfactual statements. The analysis sheds some new light on the debate on theoretical disagreements and shows that Dworkin's conception of law as an argumentative practice is not necessarily at odds with legal positivism. It rather allows us to look at it under a better light.
Acute outreach service to nursing homes: A systematic review with GRADE and triple aim approach
Authors: Kontunen Perttu J. , Holstein Ria M. , Torkki Paulus M. , Lang Eddy S. , Castrén Maaret K.
Published: January 2023

Background

People living in nursing homes face the risk of visiting the emergency department (ED). Outreach services are developing to prevent unnecessary transfers to ED.

Aims

We aim to assess the performance of acute care services provided to people living in nursing homes or long‐term homecare, focusing on ED transfer prevention, safety, cost‐effectiveness and experiences.

Materials & Methods

This review was guided by the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA). Studies were eligible for inclusion if they were peer‐reviewed and examined acute outreach services dedicated to delivering care to people in nursing homes or long‐term homecare. The service models could also have preventive components. The databases searched were Scopus and CINAHL. In addition, Robins‐I and SIGN checklists were used. The primary outcomes of prevented ED transfers or hospitalisations and the composite outcome of adverse events (mortality/Emergency Medical Service or ED visit after outreach service contact related to the same clinical condition) were graded with GRADE.

Results

Fifteen relevant original studies were found—all were observational and focused on nursing homes. The certainty of evidence for acute outreach services with preventive components to prevent ED transfers or hospitalisations was low. Stakeholders were satisfied with these services. The certainty of evidence for solely acute outreach services to prevent ED transfers or hospitalisations was very low and inconclusive. Reporting of adverse events was inconsistent, certainty of evidence for adverse events was low.

Conclusion

Published data might support adopting acute outreach services with preventive components for people living in nursing homes to reduce ED transfers, hospitalisations and possibly costs. If an outreach service is started, it is recommended that a cluster‐randomised or quasi‐experimental research design be incorporated to assess the effectiveness and safety of the service. More evidence is also needed on cost‐effectiveness and stakeholders' satisfaction. Systematic review registration number: PROSPERO CRD42020211048, date of registration: 25.09.2020.
Embedding Experiential Design Knowledge in Interactive Knowledge Graphs
Authors: Wang Ye , Goridkov Nicole , Rao Vivek , Cui Dixun , Grandi Daniele , Goucher-Lambert Kosa
Published: January 2023

Knowledge collection, extraction, and organization are critical activities in all aspects of the engineering design process. However, it remains challenging to surface and organize design knowledge, which often contains implicit or tacit dimensions that are difficult to capture in a scalable and accessible manner. Knowledge graphs (KGs) have been explored to address this issue, but have been primarily semantic in nature in engineering design contexts, typically focusing on sharing explicit knowledge. Our work seeks to understand knowledge organization during an experiential activity and how it can be transformed into a scalable representation. To explore this, we examine 23 professional designers’ knowledge organization practices as they virtually engage with data collected during a teardown of a consumer product. Using this data, we develop a searchable knowledge graph as a mechanism for representing the experiential knowledge and afford its use in complex queries. We demonstrate the knowledge graph with two extended examples to reveal insights and patterns from design knowledge. These findings provide insight into professional designers’ knowledge organization practices and represent a preliminary step toward design knowledge bases that more accurately reflect designer behavior, ultimately enabling more effective data-driven support tools for design.
Krylov Methods for Large-Scale Dynamical Systems: Application in Fluid Dynamics
Authors: Frantz R. A. S. , Loiseau J.-Ch. , Robinet J.-Ch.
Published: January 2023

In fluid dynamics, predicting and characterizing bifurcations, from the onset of unsteadiness to the transition to turbulence, is of critical importance for both academic and industrial applications. Different tools from dynamical systems theory can be used for this purpose. In this review, we present a concise theoretical and numerical framework focusing on practical aspects of the computation and stability analyses of steady and time-periodic solutions, with emphasis on high-dimensional systems such as those arising from the spatial discretization of the Navier–Stokes equations. Using a matrix-free approach based on Krylov methods, we extend the capabilities of the open-source high-performance spectral element-based time-stepper Nek5000. The numerical methods discussed are implemented in nekStab, an open-source and user-friendly add-on toolbox dedicated to the study of stability properties of flows in complex three-dimensional geometries. The performance and accuracy of the methods are illustrated and examined using standard benchmarks from the fluid mechanics literature. Thanks to its flexibility and domain-agnostic nature, the methodology presented in this work can be applied to develop similar toolboxes for other solvers, most importantly outside the field of fluid mechanics.

Authors: Adamson Brynn , Woo Mina , Liechty Toni , Chiu Chung-Yi , Wyatt Nic , Cranny Cailey , Rice Laura
Published: January 2023

Lack of disability awareness of fitness professionals is a well-established barrier to exercise participation among people with disabilities that is likely related to the lack of disability awareness training for group fitness instructors. The purposes of this study were to develop, implement, and evaluate a disability awareness training for group fitness instructors. A 90-min video training and resource manual were developed. We recruited 10 group fitness instructors from one recreation center to participate. Participants completed baseline, posttraining, and 2-month follow-up testing on survey-based outcomes including disability attitudes, confidence in exercise adaptations, and training satisfaction. Participants’ confidence to adapt fitness classes was significantly improved; however, disability attitudes were high in the pretest and not significantly different posttraining. Semistructured interviews were conducted posttraining and revealed three themes: Formal disability training is needed, Managing inclusive class dynamics, and Training suggestions and satisfaction. This training demonstrated a feasible intervention for increasing disability awareness among community-based group fitness instructors.

Published: January 2023

Guided by transactional stress theory, this study aimed to explore elite U.K. soccer coaches’ perceived stressors, the situational properties, appraisals, and coping during the COVID-19 pandemic. This study also aimed to explore any variation in stress experiences across football league standards A total of 13 professional first-team male U.K. association football coaches between 38 and 59 years of age (M = 43.00, SD = 6.94) participated in telephone (n = 5) or online (n = 8) semistructured interviews. Informed by the philosophical position of critical realism, Braun et al.’s six-phase approach to thematic analysis was used to generate competitive, organizational, and personal stressor themes. Deductive thematic analysis generated themes reflective of all situational properties of stressors identified by Lazarus and Folkman and an array of appraisal and coping strategies. Future research and recommendations for supporting coach performance and well-being post-COVID-19 pandemic are offered.

Authors: Diallo Thierno , Roberge Martin , Bérubé Anouk , Audate Pierre-Paul
Published: January 2023

Introduction

Climate change constitutes a major threat to human health. Nurses have an essential role to play in protecting populations from this threat, and to fulfil this role, they must be properly prepared. The purpose of this scoping review is to examine studies on the integration of climate change into the academic curriculum or continuing education of nurses so as to identify issues and opportunities related to this integration.

Methods and analysis

The method being used is the methodological framework proposed by Arksey and O'Malley and Levacet al. First, a search strategy using keywords and their combinations will be developed. This strategy will be applied in four bibliographic databases: MEDLINE (PubMed), CINAHL, Embase, Web of Science. Second, an initial selection of studies based on titles and abstracts will be carried out by two members of the research team using the software Covidence. They will conduct this selection process independently, with the aim of identifying relevant studies that meet the inclusion criteria for our scoping review. Third, the second stage in the selection process will be carried out by examining the full text of each article to determine which studies to include in the review. Finally, data on year of publication, authors, geographical area, article type, study objectives, methodology and key findings will be extracted from selected articles for analysis. A search of the grey literature will also be conducted to supplement the results of the bibliographic database search. The scoping review is currently ongoing. Identification of relevant literature began in the first quarter of 2022 and is expected to be completed in the first quarter of 2023.

Ethics and dissemination

Ethical approval is not required for this review. The results of this study will be presented in workshops and conferences and be submitted for publication to a peer-reviewed journal.

Authors: Taylor Michael James , Orton Elizabeth , Patel Tina , Timblin Clare , Clarke Rachel , Watson Michael Craig , Hayes Mike , Jones Matthew , Coupland Carol , Kendrick Denise
Published: January 2023

Objective

Evaluate the effectiveness of systematically delivered evidence-based home safety promotion for improving child home safety practices.

Design

Controlled before-and-after study.

Setting

Nine electoral wards in Nottingham, UK.

Participants

361 families with children aged 2–7 months at recruitment living in four intervention wards with high health, education and social need; and 401 in five matched control wards.

Intervention

Evidence-based home safety promotion delivered by health visiting teams, family mentors and children’s centres including 24 monthly safety messages; home safety activity sessions; quarterly ‘safety weeks’; home safety checklists.

Outcomes

Primary: composite measure comprising having a working smoke alarm, storing poisons out of reach and having a stairgate. Secondary: other home safety practices; medically attended injuries. Parents completed questionnaires at 12 and 24 months after recruitment plus optional three monthly injury questionnaires.

Results

At 24 months there was no significant difference between groups in the primary outcome (55.8% vs 48.8%; OR 1.58, 95% CI 0.98 to 2.55) or medically attended injury rates (incidence rate ratio 0.89, 95% CI 0.51 to 1.56), but intervention families were more likely to store poisons safely (OR 1.81, 95% CI 1.06 to 3.07), have a fire escape plan (OR 1.81, 95% CI 1.06 to 3.08), use a fireguard or have no fire (OR 3.17, 95% CI 1.63 to 6.16) and perform more safety practices (β 0.46, 95% CI 0.13 to 0.79).

Conclusions

Systematic evidence-based home safety promotion in areas with substantial need increases adoption of some safety practices. Funders should consider commissioning evidence-based multicomponent child home safety interventions.

Workers in Australian prebake aluminium smelters: update on risk of mortality and cancer incidence in the Healthwise cohort
Authors: Del Monaco Anthony , Dimitriadis Christina , Xie Sophia , Benke Geza , Sim Malcolm Ross , Walker-Bone Karen
Published: January 2023

Objectives

To investigate mortality and the rates of incident cancer among a cohort of aluminium industry workers.

Methods

Among 4507 male employees who worked in either of two Australian prebake smelters for at least 3 months, data linkage was undertaken with the Australian National Death Index and Australian Cancer Database. Standardised Mortality Ratios (SMRs) and Standardised Incidence Rates (SIRs) were estimated for the whole cohort and for: production; maintenance and office workers. SMRs and SIRs were calculated by time since first employment.

Results

Among production workers, there was an excess risk of mortality from mesothelioma (SMR 2.8, 95% CI 1.3 to 5.2), lung (SMR 1.4, 95% CI 1.0 to 1.8), prostate (SMR 1.9, 95% CI 1.3 to 2.7) and liver cancer (SMR 2.0, 95% CI 1.1 to 3.4) and the SIR was also increased for overall respiratory cancers, specifically lung cancers. An excess risk of death from stomach cancer (SMR 2.9, 95% CI 1.2 to 6.1) and Alzheimer’s disease (SMR 3.4, 95% CI 1.1 to 7.9) was seen among maintenance workers. The overall risk of death was similar to that of the Australian general population, as was mortality from cancers overall and non-malignant respiratory disease.

Conclusions

No excess risk of death from bladder cancer or non-malignant respiratory disease was found. Excess lung cancer mortality and incidence may be explained by smoking and excess mortality from mesothelioma may be explained by asbestos exposure. An excess risk of mortality from liver and prostate cancer has been shown in production workers and requires further investigation.

Radioactivity was recently discovered as a source of decoherence and correlated errors for the real-world implementation of superconducting quantum processors. In this work, we measure levels of radioactivity present in a typical laboratory environment (from muons, neutrons, and $$\gamma $$
γ
-rays emitted by naturally occurring radioactive isotopes) and in the most commonly used materials for the assembly and operation of state-of-the-art superconducting qubits. We present a GEANT-4 based simulation to predict the rate of impacts and the amount of energy released in a qubit chip from each of the mentioned sources. We finally propose mitigation strategies for the operation of next-generation qubits in a radio-pure environment.
Slowly rotating quantum dust cores and black holes
Authors: Casadio R. , Tabarroni L.
Published: January 2023

We study the effect of rotation on the spectrum of bound states for dust cores that source (quantum) black holes found in Eur. Phys. J. C 82 (2022) 10. The dust ball is assumed to spin rigidly with sufficiently slow angular velocity that perturbation theory can be applied. Like the total mass, the total angular momentum is shown to be quantised in Planck units, hence so is the horizon area. For sufficiently small fraction of mass in the outermost layer, the model admits ground states which can spin fast enough within the perturbative regime so as to describe regular rotating objects rather than black holes.
Numerical study on synchronization in the Rayleigh–Duffing and Duffing oscillators
Authors: Uriostegui-Legorreta U. , Tututi E. S.
Published: January 2023

A study on the master-slave synchronization scheme between Rayleigh–Duffing and Duffing oscillators is presented. We analyze the elastic and dissipative couplings and a combination of both. We compare the results to explore which coupling is more effective to achieve synchronization between both oscillators. The numerical results demonstrate that for the elastic or dissipative coupling at best there is complete synchronization in only one state of the slave system. However, it was also observed that depending on which oscillator acts as the master system and the coupling used, there may be partial or complete synchronization for large values of the coupling strength. When the combination of both couplings is used, there always exists complete synchronization for the two states of the slave system.
Uniform structure of solid hybrid particles and fourier flux on MLR significance of dual dynamical jumps on MHD flow: Lie group similarities
Authors: Dinesh Kumar M. , Raju C. S. K.
Published: January 2023

In the recent decades, the increasing energy demands and its applications have seen the focus shifting to the hybrid nanofluid flows but so much is still left to be investigated. This analysis is executed to explore the hydro-magnetic flow to investigate the incompressible flow and heat transfer towards a stretching surface with velocity and thermal slips. The scaling similarity transformations are created using Lie group analysis and employing these to convert nonlinear partial differential equations to the nonlinear ordinary differential equations. Here, after converting equations from dimensional to non-dimensional, we will use the BVP4C solver (MATLAB) for plotting the graphs to analyze how distinct non-dimensional parameters affect the skin friction and Nusselt number transfer rate, case 1 graphene + CNT + aluminum oxide with base fluid as water and case 2 magnesium oxide + zirconium oxide + copper oxide with water as base fluid, here taking nanoparticles without different shapes. The hybrid nanofluid temperature profile has mixed behavior, and the velocity profile increases when M rises. The hybrid nanofluid temperature profile curvature has composite behavior when [Formula: see text] rises. The link between several independent or predictor variables and one dependent or criterion variable has been examined using multilinear regression analysis (MLR). When coefficient values for many variables are subject to change, it can forecast a wide range of outcomes.
Evaluation of the structural, electronic, optical, and mechanical properties of Sb2Se3 using density functional theory
Authors: Tse Geoffrey
Published: January 2023

This work investigates the effect of band structure, optical spectra, computed elastic coefficients, Bulk-to-Shear modulus ratio, Young’s modulus and Poisson’s ratio in metal selenide compounds and their influence on electronic, optical, and elastic properties of bulk crystals using density functional theory (DFT). By studying the structural and geometrical parameters, we show that the V–VI group compound has a direct bandgap of 0.887[Formula: see text]eV and the band structure can be explained by a partial density of states (PDOS) plot. By using Pugh’s formation, the bulk-to-shear ratio can be significant in precisely determining the ductility of a material. Poisson’s ratio can provide information to examine whether the lattice crystal is ionic or covalent. Our elastic data show that the orthorhombic system is found to be unstable. The optical spectra (high absorption coefficient of [Formula: see text][Formula: see text]cm[Formula: see text], dielectric coefficient of 8.61 and reflective index of 2.93) of our current work would be beneficial to explore the applications of optoelectronic devices, especially in light-harvesting materials, covering the UV region. Our findings advance the knowledge of the structural, electronic, optical, vibrational, and mechanical properties of Sb2Se3, the key to their use, and explained the potential applications in photovoltaics perspectives.

Dynamics of uniformally collapsing system and the horizon formation
Authors: Jaiswal Annu , Srivastava Sudhir Kumar , Kumar Rajesh
Published: January 2023

In astrophysics studies, the stellar system (e.g. stars, etc.) is generally considered a spherically symmetric object, and its evolutions (e.g. collapse) depends on the nature of fluid distribution and kinematical properties that are not precisely known. One generally makes additional restrictions allowing the integration of the field equations for the studies of dynamical models. This work deals with the spherically symmetric stellar system with uniform expansion scalar ([Formula: see text]) describing the uniform collapse of stars. The uniform expansion scalar describes an important physical scenario (a generalization of the OSD model) that will exhibit a new class of collapsing stars. Here, we have parameterized the expansion scalar as exponential, power law and their combination form as a function of time [Formula: see text] so that it describes the collapsing configuration [Formula: see text]. The formation of black-hole, the horizon surface, and the thermal behavior of black-hole has also been discussed. Further, we have discussed the dynamics of uniformly collapsing system for conformally flatness. The uniform motion (collapse) of any stellar system is a fascinating phenomenon therefore the present works will produce new aspects for the studies of collapsing stellar systems and may generate broad interest among astrophysicists.
On multiplicative universal Zagreb and its subsequent indices of C4C8 carbon nanostructures
Authors: Sheikh Umber , Usman Arshad M.
Published: January 2023

Mathematical chemistry studies the chemical structure of molecules. Topological indices are numerical values which associates the chemical structure with the physical and chemical properties. Multiplicative Universal Zagreb indices are generalized degree-based topological indices which gave rise to several indices like first and second multiplicative, Zagreb and hyper-Zagreb indices, multiplicative sum and product conductivity indices. This research is designed to study the first and second multiplicative Universal Zagreb indices of carbon nanostructures (carbon nanosheet, nanotube and nanotorus) of the same chemical formula [Formula: see text] We also depict the values of first and second multiplicative, Zagreb and hyper-Zagreb indices as well as multiplicative sum and product connectivity indices for the mentioned structures. The graphical comparison for each of the multiplicative Zagreb indices is presented for all the carbon nanostructures with the same chemical formula [Formula: see text]
Multi-auxiliary Augmented Collaborative Variational Auto-encoder for Tag Recommendation
Authors: Yi Jing , Ren Xubin , Chen Zhenzhong
Published: January 2023

Recommending appropriate tags to items can facilitate content organization, retrieval, consumption, and other applications, where hybrid tag recommender systems have been utilized to integrate collaborative information and content information for better recommendations. In this article, we propose a multi-auxiliary augmented collaborative variational auto-encoder (MA-CVAE) for tag recommendation, which couples item collaborative information and item multi-auxiliary information, i.e., content and social graph, by defining a generative process. Specifically, the model learns deep latent embeddings from different item auxiliary information using variational auto-encoders (VAE), which could form a generative distribution over each auxiliary information by introducing a latent variable parameterized by deep neural network. Moreover, to recommend tags for new items, item multi-auxiliary latent embeddings are utilized as a surrogate through the item decoder for predicting recommendation probabilities of each tag, where reconstruction losses are added in the training phase to constrain the generation for feedback predictions via different auxiliary embeddings. In addition, an inductive variational graph auto-encoder is designed to infer latent embeddings of new items in the test phase, such that item social information could be exploited for new items. Extensive experiments on MovieLens and citeulike datasets demonstrate the effectiveness of our method.

TempWeb focuses on investigating infrastructures, scalable methods, and innovative software for aggregating, querying, and analyzing heterogeneous data at Web scale. Emphasis is given to data analysis along the time dimension for web data that has been collected over extended time periods. A major challenge in this regard is the sheer size of the data it exposes and the ability to make sense of it in a useful and meaningful manner for its users. It is worth noting that this trend of using big data to make inferences is not specific to Web content analytics, so work presented here might be useful in other areas, too. TempWeb has been created for this purpose and is the ideal venue to discuss all its facets.

The DoSSIER project, an European Training Network, was kicked-off in late 2019. The first PhD candidate recruiting activities took place at the beginning of the Covid-19 pandemic and the first years of the project lived in the on-line universe. Naturally, this posed certain challenges to the cohesion of our network. With some delay due to the lock-downs and travel restrictions, our first Training School was successfully organized in September 2022 and it constituted one of the few occasions we had where the members of DoSSIER network met in person. This report gives an account on the first Summer School organized by DoSSIER, for the DoSSIER Early Stage Researchers, a school set in the picturesque village of Olympiada, which gave amply opportunity of interaction between students and senior researchers in the Information Retrieval domain.

Published: January 2023

In this study, poly-lactic acid (PLA), nanohydroxyapatite (NHA), and graphene nanoplatelets (GNP) were blended to develop a nanocomposite material suitable for load-bearing bone implants with the potential for strain-sensing applications. The tensile properties and impact strength of the PLA-NHA nanocomposite were analyzed, as these are crucial biomechanical properties for load-bearing and strain-sensing applications. It was found that the impact strength decreased by 7.9% (0.05 wt% GNP) and 25.7% (0.1 wt% GNP) with increasing GNP loading compared to 0.01 wt% GNP. Besides, the biocompatibility of nanocomposites (PLA-NHA, PLA-mNHA, and PLA-mNHA-GNP) was evaluated through in-vitro analysis by attaching MG63 cells to the nanocomposites and observing their proliferation and differentiation over 7 and 21 days of incubation. The biocompatibility of the prepared nanocomposites was determined based on their ability to attach with MG63 cells, thus allowing the cells to proliferate and enhance their ability to differentiate. Results showed that the PLA-5wt%NHA nanocomposite provided better cell spreading compared to pure PLA, while the PLA-5wt%mNHA nanocomposite had the highest rate of cell proliferation. The biocompatibility of the nanocomposites was further confirmed by field emission scanning electron microscope (FESEM) imaging, MTT assays, and alkaline phosphatase (ALP) assays.

The objective of the present study was to develop a novel nanogel containing Beta vulgaris L. hydroalcoholic extract and assess its efficacy for treating testosterone‐induced alopecia. Beta vulgaris L. leaf hydroalcoholic extract nanogel (BVEN) was prepared by ionic gelation method, incorporated in carbopol 934 gel. Optimization of particle size and entrapment efficiency as the responses was carried out by central composite design response surface methodology. Prepared nanoparticles were evaluated for entrapment efficiency, particle size, zeta potential, polydispersity index, Fourier transform infrared spectroscopy, transmission electron microscopy, and differential scanning calorimetry. Nanogel was evaluated for pH, colour, appearance and homogeneity, viscosity, spreadability, in vitro release study, and stability studies. Further, 2.5% and 5% BVEN were also evaluated for antialopecic activity in Swiss albino mice by using parameters as hair growth initiation, testosterone content, total protein, prostate weight measurement, hair follicular density, anagen/telogen ratio, and histopathological studies. The resulting nanoparticles had better entrapment efficiency with particle size of 274 nm, polydispersity index of 0.259, and zeta potential of +28.8. BVEN pH 6.5, drug content, i.e., quercetin 99.84 ± 1.30% and stigmasterol 99.89 ± 1.52%, spreadability 20.3 ± 0.5925 g cm/sec, and viscosity 110 × 105 cps were observed. Stability studies showed that nanogel was stable at 4°C ± 2°C/60% ± 5% RH. It was found that 5% BVEN showed better antialopecic activity as compared to 2.5% BVEN.

Many free-floating bicycle-sharing (FFBS) operators in cold region cities will put bicycles in warehouses and suspend services in winter due to factors such as safety and maintenance costs, resulting in the corresponding travel demand no longer be met. Considering the short-distance and green travel characteristics of FFBS, the flexible bus, as a sustainable demand-responsive transit service, is a suitable alternative transportation mode. To operate such a flexible bus system, service area and operation time planning is a key stage, however, the planning methods in relevant studies are not suitable for this research scenario. In view of the above, this paper proposed a data-driven method to determine the service area and operation time of flexible buses based on FFBS data. Firstly, an FFBS trip path reconstruction algorithm consists of fine-grained road network modelling and trajectory matching is proposed. Then, in the defined time slice, incorporating the idea of ride-sharing routes generation, according to the density-based clustering principle and considering topology between trajectories, a path clustering algorithm PATHSCAN is developed to generate the one-day path clusters. After that, a frequent pattern mining algorithm is applied to the multiday path clusters, and frequent pattern results with spatio-temporal correlation will be merged into the final service area. The generated planning results will cover ride-matching trips and high-frequency riding paths. Detailed application analysis and verification are carried out by using the real data from Tianjin, China. Through the evaluation and verification under the relatively limited experimental data set, the proposed data-driven method shows ideal planning results. Flexible bus service can supplement the green short-distance travel mode after the suspension of FFBS and can avoid FFBS travel demands switched to unsustainable transportation modes to a large extent. This study will contribute to urban sustainable transportation development and improving greenness.

Changqing tight gas field has been on fashion among China in recent years. Figuring out gas and water seepage behaviors matters a lot for maximizing gas reservoir recovery. One tool for that is to conduct two-phase seepage experiment and reveal seepage features. Experiments show that gas or water’s flowing capacity has a directly positive relationship with its saturation. The larger saturation, the higher permeability. Thus, one method of determining whether a gas well produces water or not is to compare the initial water saturation with its starting-flowing saturation. If the initial gas or water saturation is larger than its critical saturation, it starts to flow. Meanwhile, this critical saturation ranges hugely. For reservoirs with high porosity, permeability, and pore structure like type I, the starting-flowing saturation is 15.6% for gas and 36.6% for water, meaning that it is easily for gas or water to reach the critical saturation and make the seepage happen. The critical saturation in reservoir of type III which has low porosity, permeability, and pore structure is as high as 28.8% for gas and 58.1% for water, indicating that high fluid saturation is needed to have it flow. Finally, four horizontal wells in Sudongnan block are analyzed to verify the method. The prediction that two of them will produce water in the beginning and the other two will not is highly in line with their production data. This method has been proved effective in the prediction of gas wells.

In this study, the molecular dynamics (MD) simulation was used to evaluate the role of imprinting temperature and the mold-cavity geometry on the imprinted Ni-P metallic glass (MG) films. Considering the outcomes of simulation, it was found that the tip-like and groove patterns showed different filling time for the imprinting process. At room temperature (300 K), the plastic deformation in the tip-like pattern was in a ring shape enclosing the mold, while the plastic deformation in the groove-pattern geometry was mainly localized at the wall of mold. Moreover, it was determined that the imprinting at high temperature (700 K) led to the shortening of pattern filling time and the decrease of loading force in both geometries. The strain concentration and localized plastic deformation were also removed in the high-temperature imprinting process. On the other hand, the unloading process at room temperature (300 K) improved the imprinting quality due to the lower elastic recovery.

Objective. The study aims to explore the correlation mechanism among metacognition, attitude toward physical exercise, and health-related behavior in high school students. Methods. A total of 869 students (17 ± 1.70) from Anhui, Zhejiang, Shandong, and Fujian provinces were selected by stratified sampling to complete the Metacognition Questionnaire, Health-Related Behavior Self-Rating Scale, Attitude Toward Physical Exercise Scale, and Depression-Anxiety-Stress Scale (Simplified Chinese version, DASS-21). Results. (1) Metacognition was negatively predictive of attitude toward physical exercise and health-related behavior (β = −0.236, P < 0.01; β = −0.239, P < 0.01) but positively predictive of negative emotion (β = 0.496, P < 0.01); (2) attitude toward physical exercise was positively predictive of health-related behavior (β = 0.533, P < 0.01) but negatively predictive of negative emotion (β = −0.336, P < 0.01); and (3) negative emotion was negatively predictive of health-related behavior (β = −0.389, P < 0.01). Conclusions. Metacognition not only has a directly predictive effect on health-related behavior but also predicts it through attitude toward physical exercise. Negative emotion also mediates the relationship between metacognition and attitude toward physical exercise.

Background. Lung adenocarcinoma (LUAD) is the most common histological subtype of non-small cell lung cancer (NSCLC) with a low 5-year survival rate, which may be associated with the presence of metastatic tumors at the time of diagnosis, especially lymph node metastasis (LNM). This study aimed to construct a LNM-related gene signature for predicting the prognosis of patients with LUAD. Methods. RNA sequencing data and clinical information of LUAD patients were extracted from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. Samples were divided into metastasis (M) and nonmetastasis (NM) groups based on LNM status. Differentially expressed genes (DEGs) between M and NM groups were screened, and then WGCNA was applied to identify key genes. Furthermore, univariate Cox and LASSO regression analyses were conducted to construct a risk score model, and the predictive performance of model was validated by GSE68465, GSE42127, and GSE50081. The protein and mRNA expression level of LNM-associated genes were detected by human protein atlas (HPA) and GSE68465. Results. A prognostic model based on eight LNM-related genes (ANGPTL4, BARX2, GPR98, KRT6A, PTPRH, RGS20, TCN1, and TNS4) was developed. Patients in the high-risk group had poorer overall survival than those in the low-risk group, and validation analysis showed that this model had potential predictive value for patients with LUAD. HPA analysis supported the upregulation of ANGPTL4, KRT6A, BARX2, RGS20 and the downregulation of GPR98 in LUAD compared with normal tissues. Conclusion. Our results indicated that the eight LNM-related genes signature had potential value in the prognosis of patients with LUAD, which may have important practical implications.
