Abstract

Two-dimensional (2D) semiconductors are regarded as promising building blocks for next-generation electronics. However, the fabrication of high quality 2D semiconductor wafers with engineered layers remains a significant challenge. Here, we develop a direct wafer bonding and debonding method for monolayer epitaxial semiconductors to overcome this challenge. The direct bonding/debonding process is operated in vacuum/glove-box and requires no intermediate layer assistance, yielding stacked 2D semiconductor wafers with ultra-clean surfaces/interfaces, wafer-scale uniformity, and control in layer numbers and interlayer twist angles. We also demonstrate the direct bonding of monolayer 2D semiconductors onto dielectric substrates (e.g., HfO2 and Al2O3) and the preserved intrinsic electronic properties is verified. The direct bonding-debonding process is fully compatible with the standard semiconductor fabrication process, propelling the lab-to-industry journey of 2D semiconductors.

Abstract

Background
The global prevalence of obesity is increasing and represents a major public health challenge. However, there is a paucity of data regarding Helicobacter pylori (H pylori) eradication in obese populations.
Aim
To examine the influence of obesity degree on H. pylori eradication in patients undergoing bariatric surgery.
Methods
A Post hoc analysis was conducted in a cohort of 204 adults patients (129 obese, 75 normal-weight) H. pylori positive included in two multicenter, prospective studies. Patients underwent a 14-day quadruple concomitant treatment, and H pylori eradication was assessed using the 13C-Urea Breath Test. The cohort was stratified according to Body Mass Index (BMI), and statistical analyses were performed using Chi-squared test, Kruskal-Wallis test, and Logistic regression.
Results
Eradication rates were significantly lower in patients with obesity compared to normal-weight individuals (68.2% vs. 88.0%, OR 0.29, 95% CI 0.13–0.63, p < 0.01). Furthermore, within the obesity group, the degree of obesity correlated with decreased eradication rates, with Class 3 (BMI 40.0-49.9) and Class 4 (BMI ≥ 50.0) obesity showing the lowest rates (67% and 51%, with an OR 0.28 and 0,15 respectively, P < 0.01).
Conclusions
Our results indicate that obesity significant influence H pylori eradication especially among severe obesity patients undergoing bariatric surgery. Tailored eradication strategies may be necessary to improve treatment efficacy in this population.
Merging Subgroup Information to Supplement Personal Information for Personal Federated Learning via Model Clustering
Authors: Cai Xuan , Zhou Wenan 
Published: August 2024

Abstract

Personalized federated learning represents a pivotal strategy for addressing the challenges posed by statistical heterogeneity in federated learning. Clients optimize their models by leveraging information from other clients through a global model. Despite clients' expectations of acquiring requisite information from global aggregation, this process inevitably leads to a loss of personalized information, particularly impacting clients with limited dataset. Consequently, the acquisition of sufficient personalized information to enhance local models becomes arduous, thereby compromising the efficacy of model personalization. In response to this challenge, we propose the Federal Merging Subgroup Information (FedMSI) method to augment personalized information in personalized federated learning. FedMSI leverages model clustering to delineate subgroup divisions of akin personalized models, aggregates cluster center models based on these divisions and enriches personalized information by incorporating subgroup information from the cluster center models. Experimental findings demonstrate that FedMSI surpasses nine state-of-the-art methods by 7.89% in terms of accuracy under identical data heterogeneity conditions, while exhibiting a 20.34% enhancement when the client data volume is small. Finally, through ablation experiments, this study reaffirms that the augmentation of personalized information through subgroup information significantly enhances the classification performance of personalized models.

Authors: Song Shuoning , Fu Yong , Dong Yingyue , Yuan Tao , Zhao Weigang 
Published: August 2024

Abstract

Aims
There were some studies reported inconsistent results on the associations between fetal sex and maternal metabolism. This study aimed to examine the effect of fetal sex on maternal glucose and lipid metabolism and perinatal outcomes in women with gestational diabetes mellitus (GDM) during pregnancy in Chinese population.
Methods
This was a retrospective cohort study including 134 women diagnosed as GDM. All of them accepted 100g oral glucose tolerance test(OGTT) during 26–29 gestational week because of positive 50g glucose challenge test(GCT) and then had a regular follow-up. The clinical and laboratory data as well as perinatal outcomes were collected from Electronic Medical Record.
Results
Of 134 pregnant women with GDM, 64(47.76%) delivered a girl and 70(52.24%) delivered a boy. Homeostasis model assessment of β-cell function (HOMA-β) in women carrying a male fetus was significantly lower than in those carrying a female fetus [176(129.09,245.56) vs. 212(150.00,307.5), p = 0.029]. There was no difference between two groups in maternal lipid metabolism. Large-for-gestational-age(LGA) fetus was more likely to happen on male fetus (14.8% vs. 3.1%, p = 0.033), but there were no difference between two groups of the other perinatal outcomes. Higher maternal fasting blood glucose(OR 5.256, 95% CI 1.318,14.469) and lower HDL-C/LDL-C in women carrying male fetus suggested higher risk of LGA.
Conclusions
Women carrying a male fetus suggested decreased maternal β-cell function and increased percentage of LGA. The different management strategy of women with GDM between male and female fetus during pregnancy is necessary.
Speed Prediction and Nearby Road Impact Analysis Using Machine Learning and Ensemble of Explainable AI Techniques

Published: August 2024

Abstract

Traffic speed prediction is an important topic in Intelligent Transport Systems (ITS). Although traffic speed prediction for real-life applications is burgeoning, the study of explaining and interpreting AI-based speed prediction is still in its initial stage. In this paper, we applied multiple advanced regression techniques such as XGBoost and Catboost optimized gradient boosting, Random Forest, and LASSO to predict traffic speed more accurately in the subsequent time windows. The experiment with prediction methods was conducted using the traffic speed data of the Seoul metropolitan road network. Each road segment represented as a node in the network is associated with neighboring roads within a configurable range. We picked heavily congested nodes as prediction targets. Then, we evaluated nearby road influences to determine critical contributions to the situation of the target nodes. We interpreted the model's output and extracted the topmost influential neighboring nodes by using an ensemble of explainable artificial intelligence (XAI) techniques such as feature importance assessment using the GINI entropy function, Recursive Feature Elimination, Shapely Additive Explanation, and a method of measuring the impact of masked nodes.We validated the XAI interpretations through traffic flow simulation by tuning the topmost influential nearby roads' speed and observing the effect on the roads' traffic congestion relief correspondingly. We also proved our solution through local explanation techniques such as Local Interpretable Model-Agnostic Explanations. Our methods are applicable to any transport network and open the door to new strategies for controlling the specific nearby roads for effective congestion relief.

Abstract

In order to explore the ceramic composition in the morphotropic phase boundary suitable for the high temperature electronic components, Pb(Sc1/2Nb1/2)O3-Pb(In1/2Nb1/2)O3-PbTiO3(PSN-PIN-PT) ceramics were designed and prepared by using the solid-state reaction method. Effect of the ceramic composition on the phase structure and electric properties of the PSN-PIN-PT ceramics were investigated. For 0.40PSN-(0.60-x)PIN-xPT(x = 0.360, 0.375, 0.390, 0.405), the increase in the PT could improve gradually Curie temperature Tc (262–292℃) and phase transition Tr−t (94–181℃). Maximum of piezoelectric coefficient d33 (578 pC/N) could be obtained in the 0.40PSN-0.21PIN-0.39PT ceramics, together with large residual polarization Pr (~ 36.7 µC/cm2) and high coercive field Ec (~ 9.3 kV/cm). These performances make the PSN-PIN-PT ceramics have great potential applications in the high temperature device.
Study of Corrosion Inhibition of Mild Steel in 0.1n Hcl Solution Using 3-[(4-Methoxy Phenyl)Imino]-1,3-Dihydro-2H- Indole-2-One
Authors: Satarkar Sahil , Dubey R. S. 
Published: August 2024

Abstract

The inhibition efficiency of the synthesized inhibitor 3-[(4-methoxy phenyl)imino]-1,3-dihydro-2H- indole-2-one in 0.1 N HCl solution was studied by using weight loss, electrochemical analysis like open circuit potential and potentiodynamic polarization methods. It was observed that the inhibition efficiency increases by increasing the concentration of the inhibitor. Maximum inhibition of 92.10% was observed at 600 ppm inhibitor concentration. The inhibitor works as an efficient anti-corrosive agent and it was also supported by electrochemical data. From the results obtained, it was observed that the data best fitted Langmuir adsorption isotherm. The polarization studies indicated that the used inhibitor is a mixed type of inhibitor. The thermodynamic parameters of activation energy and adsorption suggested that the used inhibitor supported both physical and chemical adsorption processes. The protective layer formed on the mild steel surface was analyzed by using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Analysis (EDAX) techniques. The results obtained from weight loss analysis, electrochemical analysis and surface analytical techniques were in good agreement with each other.

Abstract

Background
Herbal cake-separated moxibustion (HM) is one of the characteristic therapies for the prevention and treatment of hyperlipidemia (HLP). However, the effect of HM on plasma lipid metabolism in HLP rabbits is not clear.
Methods
New Zealand rabbits were fed with high-fat diet for 8 weeks to induce HLP model, and then HM was intervened for 8 weeks. The level of blood lipid in serum of rabbits was detected by full biochemical analyzer, and the pathological changes of liver tissue were observed by oil red O staining. Then we used ultra-high performance liquid chromatography / quadrupole time-of-flight mass spectrometry combined with multivariate statistical analysis for non-targeted lipidomic analysis.
Results
HM ameliorated hyperlipidemia induced the abnormal blood lipid level and improved liver lipid deposition induced by high cholesterol diet. Non-targeted lipidomic analysis showed that HM changed the lipid metabolism profile of HLP rabbits.
Applying OSL for dating mortar, plaster and soil samples at the archaeological site underneath the Dubrovnik cathedral

Published: August 2024

Abstract

The 20th century has brought unexpected archaeological discoveries under the Baroque Cathedral in Dubrovnik (the UNESCO World Heritage Site). In the 1980s, a church complex older than the historically recorded Romanesque basilica was excavated. The dating of these finds is crucial, not only for understanding the historical changes of the Cathedral site but also for the earliest development of the historical centre of the city of Dubrovnik. After the archaeological research of the 1980s, in 2018, the first, more extensive processing of all findings was initiated through the cooperation of five Croatian scientific institutions (the project Discovering the Old Dubrovnik Cathedrals – DiODuCat). Within the framework of the IPERION HS platform, the DiODuCat 2022 collaboration was established with the CENIEH institute in Burgos (Spain) and OSL dating was applied to mortar and plaster collected from the internal layers of key structures in the sanctuary of the “first church”, as well as to the soil collected within its nave. The resulting data supplemented radiocarbon dating (AMS 14C) of plaster samples applied in 2021 and 2022. The new data combined to indicate a somewhat different chronological development of the "first church" than was suggested by previous scholarly works, implying that it had been constructed by adapting an earlier, Late antique edifice while giving a more precise chronology to the church's refurbishments during the early Middle Ages. These data complement the already formulated scientific assumption of the DioDuCat research team based on the marble sculpture analysis and, primarily, the observations of the in situ layers of plaster in the church's sanctuary.
Profiling Users with Tag-enhanced Spherical Metric Learning for Recommendation

Published: August 2024

Abstract

With the growing complex interactions between users and items on the Internet, the difficulty of representing them has increased in Recommender Systems (RSs). Existing methods propose to capture the complex user-item interactions that implicitly associate a user with other like-minded ones. However, the learned embeddings cannot efficiently capture the similar patterns underlying users’ behaviors. Moreover, the implicitly retrieved patterns cannot be readily accurate and interpretable. To this end, we propose to leverage both users' interacted items and item tags, so as to advocate for tag-enhanced recommendations. Specifically, we propose an adaptive tag selection mechanism to ensure the quality of tag representations, so as to profile users and learn tag-enhanced representations of users/items. Additionally, we introduce a spherical optimization strategy to fully exploit the increased representation capacity of the tag-enhanced recommendation framework. We conduct numerous experiments on four real-world datasets, where our proposed tag-enhanced framework for recommendation can bring consistent performance gains and averagely achieve a 12.54% improvement regarding both Recall and NDCG metrics.
What will the future bring? – Socio-economic challenges to herder households in the Dzungarian Gobi, Mongolia

Published: August 2024

Abstract

Nomadic pastoralism is still practiced by around one-third of the Mongolian population. Recent socio-economic constraints have challenged pastoral livelihoods and led to declines in herder household numbers. Meanwhile, livestock numbers have risen countrywide, threatening overall rangeland health and biodiversity conservation. In the Mongolian Gobi, herder families fully depend on livestock production. Little is known about the current and future trends of their livelihoods and its compatibility with protected area goals to reduce livestock numbers. We combined data from semi-structured interviews and focus group discussions in the Great Gobi B strictly protected area with secondary data on regional and national herder household income and livestock numbers. We determined the importance of social networks, the willingness to continue a herding lifestyle, and the involvement of herders in the protected area management. Our data confirmed that herding is no longer centred around a subsistence lifestyle but rather around cashmere production. Herder families are currently still increasing livestock numbers, which is counter to protected area goals. Costs for education, health care, travelling, and modern communication are high in the economic reality of a market economy and drive the need to increase livestock numbers. Most of the young herder generation are employed urban centres with limited time to support the family herding household. Herders, despite valuing pastures within protected areas, faced challenges due to inadequate communication and conflicting livestock numbers goals. We conclude that herders in the Great Gobi B SPA are reaching livestock numbers which are neither socio-economically nor ecologically sustainable.

Published: August 2024

Abstract

This paper presents a microzonation study of the urban area of Algiers city in Algeria, using 640 microtremor measurements and horizontal over vertical spectral ratios (H/V). The sesmic history of the region changed from moderate to high seismic activity since the destructive Boumerdes earthquake (Mw = 6.8) on May 21st, 2003. The area's geological context suggests the prevalence of alluvial soils, especially in its central part, which undergoes significant site amplification. The seismic design codes use the concept of soil class to categorize common-soil conditions into broad classes bounded by typical average shear wave velocities of the top 30 m (Vs30). In the absence of Vs30, using H/V measurements provides comparable site information and offers more descriptive value than Vs30 for deep soils, the objective is to prepare a first order microzonation map using a new classification scheme proposed by Laouami et al. (2018) based on H/V target spectral ratio functions defined for each of the 4 RPA99/2003 soil classes (S1, S2, S3 and S4). It serves as a practical tool to empirically determine the site class for 640 sites using microtremor measurements, along with identifying their fundamental frequencies and estimating the average shear wave velocities of the top 30 meters. The comparison of the obtained iso-frequency and site classification maps with the in situ data reveals a high correlation level, emphasizing the new scheme's robustness. The results obtained are vital for urban planning and seismic analysis, improving Algiers' resilience and guiding structural design against seismic loads.

Abstract

Viruses, as nanoscale entities with limited proteomes, must efficiently infect target cells using their available resources. During infection, individual virions induce specific cellular signaling within the virus-cell interface, a nanoscale patch of the plasma membrane in contact with the virus. However, virus-induced receptor recruitment and cellular activation are transient processes that occur within minutes and at the nanoscale level. Hence, the temporal and spatial kinetics of such early events often remain poorly understood due to technical limitations. To address this challenge, we developed a novel protocol to covalently immobilize unmodified influenza A viruses on glass surfaces before exposing them to live epithelial cells. This approach extends the observation time for virus-plasma membrane interaction while preserving the viruses' native state for uncompromised cell interaction. Using single-molecule super-resolution microscopy, we investigated virus-receptor interaction showing that viral receptors are not immobilized by the virus but rather slowed down, which leads to a specific local receptor accumulation and turnover. We further followed the dynamics of clathrin-mediated endocytosis at the single-virus level and demonstrate the recruitment of adaptor protein 2 (AP-2), previously thought to be uninvolved in influenza A virus infection. Finally, we examined the nanoscale organization of the actin cytoskeleton at the virus-binding site, showing a local and dynamic response of the cellular actin cortex to the infecting virus. Our findings provide novel insights into the fundamental process of virus-cell interaction and demonstrate the versatility and potential impact of our approach on virus-cell biology.

Abstract

Hydrogen-bonded organic frameworks (HOFs), with their excellent biocompatibility, diverse chemical functionalities, and well-organized porous structures, represent a versatile and promising platform for biomedical applications. However, manufacturing pristine HOFs powders into lightweight, ultrathin, freestanding membranes compatible with soft tissues of arbitrary shape and size has been a significant challenge. Herein, we successfully prepared shape-adaptive HOFs-based matrix membranes (HMMs) using a polymer-assisted liquid-air interface technique. These membranes are capable of conforming to tissues of different sizes and shapes, effectively stopping bleeding and exhibiting high water-vapor permeability. Remarkably, in vitro and in vivo studies in mice demonstrated that the tissue-conformable membranes accelerate wound healing by regulating the inflammatory environment of the damaged tissue and promoting faster re-epithelialization. Furthermore, RNA-seq analysis and mechanistic studies revealed that HMMs effectively reduce inflammation and facilitate the transition from the proliferative stage to the remodeling stage of skin development. This work provides new insights into the use of multifunctional HOFs in healthcare management and paves the way for hybridizing HOFs with polymers for diverse applications.
