Abstract2D compounds (A = Al, Ga, In, and B = S, Se, and Te) with intrinsic structural defects offer significant opportunities for high‐performance and functional devices. However, obtaining 2D atomic‐thin nanoplates with non‐layered structure on SiO2/Si substrate at low temperatures is rare, which hinders the study of their properties and applications at atomic‐thin thickness limits. In this study, the synthesis of ultrathin, non‐layered α‐In2Te3 nanoplates is demonstrated using a BiOCl‐assisted chemical vapor deposition method at a temperature below 350 °C on SiO2/Si substrate. Comprehensive characterization results confirm the high‐quality single crystal is the low‐temperature cubic phase α‐In2Te3 , possessing a noncentrosymmetric defected ZnS structure with good second harmonic generation. Moreover, α‐In2Te3 is revealed to be a p‐type semiconductor with a direct and narrow bandgap value of 0.76 eV. The field effect transistor exhibits a high mobility of 18 cm2 V−1 s−1, and the photodetector demonstrates stable photoswitching behavior within a broadband photoresponse from 405 to 1064 nm, with a satisfactory response time of τrise = 1 ms. Notably, the α‐In2Te3 nanoplates exhibit good stability against ambient environments. Together, these findings establish α‐In2Te3 nanoplates as promising candidates for next‐generation high‐performance photonics and electronics.

Published: January 2024

AbstractElectrochemical capacitors (ECs) show great perspective in alternate current (AC) filtering once they simultaneously reach ultra‐fast response and high capacitance density. Nevertheless, the structure‐design criteria of the two key properties are often mutually incompatible in electrode construction. Herein, it is proposed that combining vertically oriented porous carbon with enhanced interfacial capacitance (Ci) can efficiently solve this issue. Theoretically, the density function theory calculation shows that the Ci of a carbon electrode can be enhanced by boron doping due to the corresponding compact induced charge layer. Experimentally, the vertical‐oriented boron‐doped graphene nanowalls (BGNWs) electrodes, whose Ci is enhanced from 4.20 to 10.16 µF cm−2 upon boron doping, are prepared on a large scale (480 cm2) using a hot‐filament chemical vapor deposition technique (HFCVD). Owing to the high Ci and vertically oriented porous structure, BGNWs‐based EC has a high capacitance density of 996 µF cm−2 with a phase angle of − 79.4° at 120 Hz in aqueous electrolyte and a high energy density of 1953 µFV2 cm−2 in organic electrolyte. As a result, the EC is capable of smoothing 120 Hz ripples for 60 Hz AC filtering. These results provide enlightening insights on designing high‐performance ECs for high‐frequency applications.

Published: January 2024

AbstractBackgroundCisplatin (CDDP)‐based chemotherapy has emerged as the primary treatment for muscle‐invasive bladder cancer and metastatic bladder cancer. Nevertheless, a significant proportion of patients experience rapidly developed chemoresistance, leading to treatment ineffectiveness. Existing evidence suggests that chemoresistance is governed by various factors, including tumor stem cells, epithelial mesenchymal transition, and reactive oxygen species (ROS). However, limited research has been conducted on the role of PRDX2, a crucial ROS scavenger, in the modulation of chemoresistance in bladder cancer.MethodsCisplatin‐resistant cell lines were established using the concentration gradient overlay method, and differentially expressed genes in resistant cells were screened through RNA sequencing. The expression of PRDX2 in cells and tissues was assessed using RT‐qPCR, Western Blot, and immunohistochemistry. The expression of PRDX2 in bladder cancer and adjacent tissues was evaluated using a bladder cancer tissue microarray. Furthermore, the impact of PRDX2 knockdown on tumor formation and metastasis was investigated in vivo by applying subcutaneous tumor xenografts tail vein metastasis assays.ResultsWe demonstrated that PRDX2 is significantly upregulated in bladder tumors and cisplatin‐resistant bladder tumor cell lines. Overexpression of PRDX2 can promote tumor proliferation, migration, and invasion both in vitro and in vivo. We have found that knockdown of PRDX2 expression can effectively reverse cell resistance to cisplatin. Mechanistically, our findings suggest that PRDX2 is involved in regulating tumor stemness and epithelial‐mesenchymal transition (EMT). Knockdown of PRDX2 affects the PI3K‐AKT and mTOR signaling pathways, thereby influencing tumor stemness and EMT, ultimately impacting the chemotherapy resistance of the tumor.ConclusionsThis study provides a new insight into the regulation of chemotherapy resistance in bladder cancer by PRDX2. Targeting PRDX2 can serve as a potent therapeutic target for chemotherapy resistance.

AbstractLonicerae japonicae (L. japonicae) flos is a medical and food homology herb. This study investigated the phenolic acid and flavonoid contents in L. japonicae flos water extract solution (LJWES) and the preventive effects of LJWES against liver fibrogenesis via FL83B cells and rats. LJWES contains many polyphenols, such as chlorogenic acid, morin, and epicatechin. LJWES increased cell viability and decreased cytotoxicity in thioacetamide (TAA)‐treated FL83B cells (75 mM) (p < .05). LJWES decreased (p < .05) gene expressions of Tnf‐α, Tnfr1, Bax, and cytochrome c but upregulated Bcl‐2 and Bcl‐xl in TAA‐treated cells; meanwhile, increased protein levels of P53, cleaved caspase 3, and cleaved caspase 9 in TAA treated cells were downregulated (p < .05) by LJWES supplementation. In vivo, results indicated that TAA treatment increased serum liver damage indices (alanine aminotransferase [ALT] and alkaline phosphatase [ALP]) and cytokines (interleukin‐6 and transforming growth factor‐β1) levels and impaired liver antioxidant capacities (increased thiobarbituric acid reactive substance value but decreased catalase/glutathione peroxidase activities) in rats (p < .05) while LJWES supplementation amended (p < .05) them. Liver fibrosis scores, collagen deposition, and alpha‐smooth muscle actin deposition in TAA‐treated rats were also decreased by LJWES supplementation (p < .05). To sum up, LJWES could be a potential hepatoprotective agent against liver fibrogenesis by enhancing antioxidant ability, downregulating inflammation in livers, and reducing apoptosis in hepatocytes.

AbstractThe sub‐mountainous tea gardens of the Dooars region of West Bengal, which contribute approximately 25% of the national tea yield, are constantly fighting with diminishing soil fertility. Inorganic alternatives like chemical fertilizers can provide easier yet short‐term solutions, as their prolonged and indiscriminate usage leaches the soil, devouring its productivity, increasing the soil's heavy metal contents, and subsequently accumulating those heavy metals in leaves. A plausible substitution in this scenario could be the use of organic alternatives like composting or biofertilizer. Although references to such alternative means are found in the literature, a holistic approach targeting plant growth promotion along with mitigating soil metal toxicity is lacking. Keeping this background in mind, this pilot study was designed to optimize the dosage of novel biofertilizers (using resident and alien flora) that can reduce heavy metal loads and residual toxicity in soil, thereby improving overall soil health and tea production. Two potential metallophilic plant growth‐promoting strains of Bacillus sp. (previously reported) were selected and applied to potted tea plants of two different varieties of tea: TV9 and TV25. Among the two modes of treatment tested: solid treatment (compost amended with bacterial culture) and liquid treatment (cell pellets mixed in water suspension), the water suspension‐based direct application of resident soil bacteria showed the highest physiological growth with reduced metal toxicity. Based on physiological data and physico‐chemical data collected, it was observed that direct application of bacteria showed better results in both plant and soil health improvement in comparison to regular compost amended with beneficial microflora. Therefore, this small‐scale pilot study aimed to optimize the dosage and mode of application of novel biofertilizers for improved soil and plant health.

Published: January 2024

AbstractThe past years since the publication of our review on subsystem density‐functional theory (sDFT) (WIREs Comput Mol Sci. 2014, 4:325–362) have witnessed a rapid development and diversification of quantum mechanical fragmentation and embedding approaches related to sDFT and frozen‐density embedding (FDE). In this follow‐up article, we provide an update addressing formal and algorithmic work on sDFT/FDE, novel approximations developed for treating the non‐additive kinetic energy in these DFT/DFT hybrid methods, new areas of application and extensions to properties previously not accessible, projection‐based techniques as an alternative to solely density‐based embedding, progress in wavefunction‐in‐DFT embedding, new fragmentation strategies in the context of DFT which are technically or conceptually similar to sDFT, and the blurring boundary between advanced DFT/MM and approximate DFT/DFT embedding methods.This article is categorized under:

Interdisziplinär ausgerichtetes Operationsspektrum in Kooperation von Viszeralchirurgie und Gynäkologie
Authors: Garlaschelli Gabriele , Ignativ Atanas , Meyer Frank 
Published: January 2024

Zusammenfassung
Ziel
Die vorliegende Kurzübersicht soll in prägnanter Form aus bevorzugt operativer Sicht die wichtigsten gynäkologischen Fragestellungen erläutern, welche auch für Allgemein- und ViszeralchirurgInnen relevant sein können, sowie wesentliche gynäkologische Aspekte primär viszeralchirurgischer Krankheitsbilder aufzeigen.

Methode
Narrative Übersicht zum Thema der gynäkologisch/allgemein- und viszeralchirurgischen interdisziplinären Kooperation mithilfe von PubMed® sowie der Cochrane Llibrary unter Verwendung von Suchbegriffen wie „operative profile of abdominal surgery and gynecology“, „interdisciplinary surgery aspects of gynecology/abdominal surgery“ sowie „interdisciplinary surgical approach – surgical complication“.

Ergebnisse (Eckpunkte)
Viele primär gynäkologische Krankheitsbilder können, allein durch die engen anatomischen Verhältnisse, auch an abdominellen Organen auftreten. Ebenso können primär viszeralchirurgische Pathologien auch eine Involvierung der gynäkologischen Organe bedingen. Hierdurch kann eine intraoperative Zusammenarbeit notwendig werden. Auch prä- und postoperativ kann aufgrund diagnostischer Unsicherheit oder im Rahmen von Komplikationen eine Interdisziplinarität gefordert sein. Dabei können ein fächerübergreifendes Wissen der therapierenden ÄrztInnen sowie die enge Kooperation der gefragten Fachrichtungen das Outcome der betroffenen Patientinnen verbessern.

Schlussfolgerung
Viele Krankheitsbilder erstrecken sich nicht nur bis an die Grenze der einzelnen Fachbereiche, sondern können darüber hinaus auch weitere Systeme betreffen. Für eine optimale Therapie ist es daher notwendig, auch solche Aspekte der Pathologien zu kennen sowie strukturierte Abläufe der interdisziplinären Kooperation zu etablieren.
A review of adaptable conventional image processing pipelines and deep learning on limited datasets

Published: January 2024

AbstractThe objective of this paper is to study the impact of limited datasets on deep learning techniques and conventional methods in semantic image segmentation and to conduct a comparative analysis in order to determine the optimal scenario for utilizing both approaches. We introduce a synthetic data generator, which enables us to evaluate the impact of the number of training samples as well as the difficulty and diversity of the dataset. We show that deep learning methods excel when large datasets are available and conventional image processing approaches perform well when the datasets are small and diverse. Since transfer learning is a common approach to work around small datasets, we are specifically assessing its impact and found only marginal impact. Furthermore, we implement the conventional image processing pipeline to enable fast and easy application to new problems, making it easy to apply and test conventional methods alongside deep learning with minimal overhead.
Residual stress measurement in engine block—an overview
Authors: Alipooramirabad Houman , Kianfar Sina , Paradowska Anna , Ghomashchi Reza 
Published: January 2024

AbstractSignificant residual stresses are often generated during the manufacturing of cast Al-Si alloy engine blocks due to differential cooling rates, the mismatch in the thermo-physical properties of adjacent materials in direct contact and volumetric changes caused by solid-state phase transformations during cooling. These may be modified during heat treatment and operation. These residual stresses may lead to distortion (affecting performance and economy) or premature failure of the engine block. For this reason, it is of fundamental importance to have reliable numerical and experimental methods for characterizing the residual stresses in the engine blocks at several steps during the manufacturing process. Sectioning and neutron diffraction techniques have been widely used to determine the residual stresses in the engine blocks. Numerical techniques have been developed to predict these residual stress but require experimental validation. The authors reviewed several numerical and experimental studies of residual stress evolution in engine blocks and showed how the residual stresses, microstructures, and mechanical properties are correlated.

Published: January 2024

AbstractThe mechanical properties of natural snow play a crucial role in understanding glaciers, avalanches, polar regions, and snow-related constructions. Research has concentrated on how the mechanical properties of snow vary, primarily with its density; the integration of cutting-edge techniques like micro-tomography with traditional loading methods can enhance our comprehension of these properties in natural snow. This study employs $$\mu$$
μ
CT imaging and uniaxial compression tests, along with the Digital Volume Correlation (DVC) to investigate the density-dependent material properties of natural snow. The data from two snow samples, one initially non-compressed (test 1) and the other initially compressed (test 2), were fed into Burger’s viscoelastic model to estimate the material properties. $$\mu$$

C, using a constant deformation rate (0.2 mm/min). The relative density of the snow, ranging from 0.175 to 0.39 (equivalent to 160–360 kg/m$$^3$$

), is determined at each load step through binary image segmentation. Modulus and viscosity terms, estimated from Burger’s model, exhibit a density-dependent increase. Maxwell and Kelvin–Voigt moduli range from 0.5 to 14 MPa and 0.1 to 0.8 MPa, respectively. Viscosity values for the Maxwell and Kelvin–Voigt models vary from 0.2 to 2.9 GPa-s and 0.2 to 2.3 GPa-s within the considered density range, showing an exponent between 3 and 4 when represented as power functions. Initial grain characteristics for tests 1 and 2, obtained through image segmentation, reveal an average Specific Surface Area (SSA) of around 55 1/mm and 40 1/mm, respectively. The full-field strain distribution in the specimen at each load step is calculated using the DVC, highlighting strong strain localization indicative of non-homogeneous behavior in natural snow. These findings not only contribute to our understanding of natural snow mechanics but also hold implications for applications in fields such as glacier dynamics and avalanche prediction.
Exploring settler-Indigenous engagement in food systems governance

AbstractWithin food systems governance spaces, civil society organizations (CSOs) play important roles in addressing power structures and shaping decisions. In Canada, CSO food systems actors increasingly understand the importance of building relationships among settler and Indigenous peoples in their work. Efforts to make food systems more sustainable and just necessarily mean confronting the realities that most of what is known as Canada is unceded Indigenous territory, stolen land, land acquired through coercive means, and/or land bound by treaty between specific Indigenous groups and the Crown. CSOs that aim to build more equitable food systems must thus engage with the ongoing impacts of settler colonialism, learn/unlearn colonial histories, and build meaningful relationships with Indigenous peoples. This paper explores how settler-led CSOs engage with Indigenous communities and organizations in their food systems governance work. The research draws on 71 semi-structured interviews with CSO leaders engaged in food systems work from across Canada. Our analysis presents an illustrative snapshot of the complex and ongoing processes of settler-Indigenous engagement, where many settler-led CSOs aim to work more closely with Indigenous communities and organizations. However, participants also recognize that most existing engagements remain insufficient. We share CSOs’ practices, tensions, and lessons learned as reflections for scholars and practitioners interested in the continuous journey of building settler-Indigenous partnerships and reimagining more just and sustainable food systems, work which requires iterative and critically reflexive learning.
Coupled fixed point results for new classes of functions on ordered vector metric space
Authors: Çevik C. , Özeken Ç. C. 
Published: January 2024

AbstractThe contraction condition in the Banach contraction principle
forces a function to be continuous. Many authors overcome this obligation and
weaken the hypotheses via metric spaces endowed with a partial order. In this paper,
we present some coupled fixed point theorems for the functions having mixed
monotone properties on ordered vector metric spaces, which are more general
spaces than partially ordered metric spaces. We also define the double monotone
property and investigate the previous results with this property. In the last
section, we prove the uniqueness of a coupled fixed point for non-monotone functions.
In addition, we present some illustrative examples to emphasize that our
results are more general than the ones in the literature.
Tuning mechanical behaviors of highly entangled hydrogels with the random distribution of mobile entanglements
Authors: Liu Jinlong , Lu Di , Chen Bin 
Published: January 2024

AbstractHighly entangled hydrogels exhibit excellent mechanical properties, including high toughness, high stretchability, and low hysteresis. By considering the evolution of randomly distributed entanglements within the polymer network upon mechanical stretches, we develop a constitutive theory to describe the large stretch behaviors of these hydrogels. In the theory, we utilize a representative volume element (RVE) in the shape of a cube, within which there exists an averaged chain segment along each edge and a mobile entanglement at each corner. By employing an explicit method, we decouple the elasticity of the hydrogels from the sliding motion of their entanglements, and derive the stress-stretch relations for these hydrogels. The present theoretical analysis is in agreement with experiment, and highlights the significant influence of the entanglement distribution within the hydrogels on their elasticity. We also implement the present developed constitutive theory into a commercial finite element software, and the subsequent simulations demonstrate that the exact distribution of entanglements strongly affects the mechanical behaviors of the structures of these hydrogels. Overall, the present theory provides valuable insights into the deformation mechanism of highly entangled hydrogels, and can aid in the design of these hydrogels with enhanced performance.
Nonlinear dynamics of a circular curved cantilevered pipe conveying pulsating fluid based on the geometrically exact model

Published: January 2024

AbstractDue to the novel applications of flexible pipes conveying fluid in the field of soft robotics and biomedicine, the investigations on the mechanical responses of the pipes have attracted considerable attention. The fluid-structure interaction (FSI) between the pipe with a curved shape and the time-varying internal fluid flow brings a great challenge to the revelation of the dynamical behaviors of flexible pipes, especially when the pipe is highly flexible and usually undergoes large deformations. In this work, the geometrically exact model (GEM) for a curved cantilevered pipe conveying pulsating fluid is developed based on the extended Hamilton’s principle. The stability of the curved pipe with three different subtended angles is examined with the consideration of steady fluid flow. Specific attention is concentrated on the large-deformation resonance of circular pipes conveying pulsating fluid, which is often encountered in practical engineering. By constructing bifurcation diagrams, oscillating shapes, phase portraits, time traces, and Poincare maps, the dynamic responses of the curved pipe under various system parameters are revealed. The mean flow velocity of the pulsating fluid is chosen to be either subcritical or supercritical. The numerical results show that the curved pipe conveying pulsating fluid can exhibit rich dynamical behaviors, including periodic and quasi-periodic motions. It is also found that the preferred instability type of a cantilevered curved pipe conveying steady fluid is mainly in the flutter of the second mode. For a moderate value of the mass ratio, however, a third-mode flutter may occur, which is quite different from that of a straight pipe system.
