Authors: Chen Qifa , Hai Yang , Bai Yuhang , Xu Zhiqiang 
Published: September 2023

Abstract
Shape control is the core link in the production of sheet steel products, and the shape mainly depends on the control of the original roll profile of the rolling rolls. The wear of the roll is inevitable in the process of strip rolling. The electronic temperature control technology of the roll profile utilizes a heat source to drive flexible adjustment of the roll profile and directionally achieves the preset, adjustment, compensation, and other roll shape control requirements of local rolls. This article establishes an electronic temperature controlled roll model and uses numerical simulation methods to research the wear compensation of electronic temperature controlled rolls. The reliability of the model is verified using an electronic temperature controlled roll experimental platform, providing an online dynamic self-compensation method for roll wear.

Abstract
As an advanced wafer dicing technology, stealth dicing has the advantage of better-cutting quality and faster-cutting speed than traditional blade dicing technology and has a broad application prospect for the future cutting of large and ultra-thin silicon wafers. The stealth dicing equipment involves two processes, i.e., wafer altimetry and follow-through processing in silicon wafer cutting, the altimetry accuracy of which determines the processing precision. In this paper, polynomial fitting, linear interpolation, and cubic spline interpolation are applied to predict the altimetry data at different speeds to achieve high-speed and high-precision altimetry under various speed conditions. The research shows that the prediction accuracy of the three methods is less than 1 μm. The linear interpolation has the highest accuracy during the altimetry speeds of 500 mm/s ~ 1500 mm/s. The polynomial fitting can achieve better prediction results by selecting the best fitting parameter when the altimetry speeds are 1500 mm/s ~ 2500 mm/s. The cubic spline interpolation is more suitable for the processing of data sampled at altimetry speeds between 2500 mm/s and 3000 mm/s.

Published: September 2023

Abstract
Breath figure technology’s potential for surface modification of fibers to enable new functions in wearables is attractive. However, the development of extensible, multifunctional elastic fibers with hierarchically porous architectures remains a difficulty. We study a new technique for fiber surface modification based on the modified breath figure technique, which includes material selection, interfacial self-assembly, and pre-stretch ratio. The fabricated hierarchically porous elastic fibers exhibit features like finger joint buckled skin and a unique stretchable buckled porous structure. Influential factors such as elastic fiber base diameter, brick polymer solution concentration, and pre-stretch ratio were studied. This study presents a novel design and preparation of functional fiber materials with porous microstructures.

Simulation Research on Residual Stress of Swage Autofrettage-processed High-Pressure Cylinder
Authors: Sun Lihua , Zhou Rongxuan , Li Guiqin , Li Jianing , Mitrouchev Peter 
Published: September 2023

Abstract
The vital component of the high-pressure pump is the high-pressure cylinder, which undergoes pulsating cyclic loads during operation. This exposure can lead to fatigue cracking and limit the pump’s overall performance. To address this issue, a swage autofrettage treatment method for the high-pressure cylinder is proposed based on the principles of autofrettage technology. The structure parameters of the mandrel are designed to optimize its role in the treatment process. Subsequently, a swage autofrettage simulation model is established, considering the Bauschinger effect to analyze the distribution of residual stress about the mandrel interference percentage. The results demonstrate that the swage autofrettage treatment improves the stress distribution in the high-pressure cylinder, causing the inner wall surface to undergo a circumferential residual compressive stress. Within a specific range, the Bauschinger effect becomes more significant as the mandrel interference percentage increases. This study provides insights for enhancing the durability and performance of high-pressure cylinders while adhering to mechanical engineering standards.

The structure and mechanical properties of high-strength aluminum alloys fabricated with wire arc additive manufacturing
Authors: Ma Yue , Wang Tao 
Published: September 2023

Abstract
In this study, optimized wire arc additive manufacturing (WAAM) process parameters were used to fabricate 2319 aluminum alloy samples. The microstructure and mechanical properties of printed samples were carefully studied. The results showed that 2319 aluminum alloy samples manufactured by WAAM had good surface quality, and no metallurgical defects such as cracks or incomplete fusion were found in the samples. The printed 2319 aluminum alloy sample was mainly composed of the matrix phase ɑ (Al) and strengthening phase θ (Al2Cu). It was found that the quantity and distribution of strengthening phases were affected by the heat treatment process. Compared to the T4-state heat treatment, the distribution of the strengthening phase a (Al2Cu) was more uniform and its quantity was significantly increased after the T6-state (530 °C/20 h+170 °C/18 h) heat treatment. As a result, the results showed that its transverse tensile strength was 436.3 MPa and the elongation was 12%. Meanwhile, the longitudinal tensile strength was 376.3 MPa, and the elongation was 8.5%, which was much higher than the performance of casted 2319 aluminum alloy. The fracture surfaces of 2319 samples had small and uniform dimples, which indicated that they belonged to ductile fracture.
Community forestry dominates the recent land greening amid climate change in Nepal

Published: September 2023

Abstract
The Himalaya Plateau including Nepal is ‘greening up’ that has important implications to ecosystem services such as water supply, carbon sequestration, and local livelihoods. Understanding the combined causes behind greening is critical for effective policy makings in forest management and climate change adaptation towards achieving sustainable development goals. This national scale study comprehensively examined the natural and anthropogenic drivers of the long-term trend of vegetation dynamics across Nepal by correlation analysis and multiple linear regression analysis. We integrated multiple sources of data including global satellite-based leaf area index (LAI), climate data, landcover data, and forest land management information. Our study reveals a remarkable annual mean LAI increase of 22% (0.009 m2 m−2 yr−1) (p < 0.05) from 1982 to 2020, with an acceleration in the rate of increase to 0.016 m2 m−2 yr−1 (p < 0.05) after 2004. The community forestry (CF) program, forest area changes, and soil moisture availability accounted for 40%, 12%, and 10% of LAI temporal variability, respectively. Our analysis found soil moisture and forest area changes to be the primary drivers of the greening trend before 2004, while CF and forest expansion were the dominant factors thereafter. Additionally, interannual vegetation dynamics were significantly influenced by winter precipitation, incoming solar radiation, and pre-monsoon soil moisture. The projections based on four Earth System Models from Coupled Model Intercomparison Project Phase 6 suggest that Nepal’s greening trend is expected to continue at a rate of 0.009 m2 m−2 yr−1 (p < 0.05) throughout the 21st century. We conclude that forest management program (CF) amid climate change that alters water and energy conditions have enhanced land greening, posing both opportunities and risks to ecosystem services in Nepal. This study provides much needed national-level information for developing forest management policies and designing Nature-based Solutions to respond to climate change and increasing demands for ecosystem services in Nepal.

Published: September 2023

Abstract
Printed electronics (PE) is growing rapidly through innovation in several pathways: ink formulation, substrate improvement, printing and drying process optimization. All these developments are combining to enable the production of a new generation of PE devices that reduce e-waste. However, the main question of the recyclability of these devices is critical. This article is focused on (1) the industrial fabrication of recyclable substrates prepared by roll-to-roll printing using flexographic printing units to cover paper with shellac solution and (2) the environmental impact assessment of new development of PE. To investigate the performance of the produced substrate, a battery-less near-field communication antenna was printed with a flatbed screen printing using silver ink. The print quality, electrical resistance and the basic functional characterization of these paper-based antennas were investigated and reported. To validate the functionality of printed devices, a

Published: September 2023

Abstract

Objectives
Critical hyperbilirubinemia in preterm neonates, a condition requiring greater attention, is treated with phototherapy or exchange transfusion when bilirubin results exceed gestational age and age-specific medical decision levels (MDLs) to prevent bilirubin-induced neurologic damage. Conventional evaluation involves multiple manual steps and is poised to inconsistencies and delays.

Methods
We designed and implemented an electronic clinical decision support (CDS) tool to identify and alert neonatal intensive care unit clinicians of critical hyperbilirubinemia with a SmartZone alert. We evaluated the performance of our manual evaluation workflow, the accuracy of the electronic CDS tool, and the outcome of the electronic CDS tool to reduce the time to place orders for interventions.

Results
Among the 22 patients who met the criteria to have phototherapy ordered before implementing the electronic CDS tool, 20 (90%) had phototherapy ordered. Fourteen (70%) phototherapy orders were placed less than 24 hours, 4 phototherapy orders were placed 24 to 72 hours, and 2 orders were placed more than 72 hours after bilirubin results exceeded the corresponding MDLs. Among the 15 patients who met the criteria to have phototherapy ordered after implementing the electronic CDS tool, all (100%) received phototherapy orders, with 14 (93%) placed less than 24 hours and 1 order placed less than 48 hours. The electronic CDS tool identified all eligible patients correctly. The proportion of phototherapy ordered less than 24 hours increased from 70% to 93% after the implementation of the electronic CDS tool.

Conclusions
The electronic CDS tool promoted more appropriate and timely intervention orders to manage critical hyperbilirubinemia in preterm neonates.
The CAM lineages of planet Earth

Published: September 2023

Abstract

Background and Scope
The growth of experimental studies of crassulacean acid metabolism (CAM) in diverse plant clades, coupled with recent advances in molecular systematics, presents an opportunity to re-assess the phylogenetic distribution and diversity of species capable of CAM. It has been more than two decades since the last comprehensive lists of CAM taxa were published, and an updated survey of the occurrence and distribution of CAM taxa is needed to facilitate and guide future CAM research. We aimed to survey the phylogenetic distribution of these taxa, their diverse morphology, physiology and ecology, and the likely number of evolutionary origins of CAM based on currently known lineages.

Results and Conclusions
We found direct evidence (in the form of experimental or field observations of gas exchange, day–night fluctuations in organic acids, carbon isotope ratios and enzymatic activity) for CAM in 370 genera of vascular plants, representing 38 families. Further assumptions about the frequency of CAM species in CAM clades and the distribution of CAM in the Cactaceae and Crassulaceae bring the currently estimated number of CAM-capable species to nearly 7 % of all vascular plants. The phylogenetic distribution of these taxa suggests a minimum of 66 independent origins of CAM in vascular plants, possibly with dozens more. To achieve further insight into CAM origins, there is a need for more extensive and systematic surveys of previously unstudied lineages, particularly in living material to identify low-level CAM activity, and for denser sampling to increase phylogenetic resolution in CAM-evolving clades. This should allow further progress in understanding the functional significance of this pathway by integration with studies on the evolution and genomics of CAM in its many forms.
Cardinality optimization in constraint-based modelling: application to human metabolism
Authors: Fleming Ronan M T , Haraldsdottir Hulda S , Minh Le Hoai , Vuong Phan Tu , Hankemeier Thomas , Thiele Ines 
Published: September 2023

AbstractMotivationSeveral applications in constraint-based modelling can be mathematically formulated as cardinality optimization problems involving the minimization or maximization of the number of nonzeros in a vector. These problems include testing for stoichiometric consistency, testing for flux consistency, testing for thermodynamic flux consistency, computing sparse solutions to flux balance analysis problems and computing the minimum number of constraints to relax to render an infeasible flux balance analysis problem feasible. Such cardinality optimization problems are computationally complex, with no known polynomial time algorithms capable of returning an exact and globally optimal solution.ResultsBy approximating the zero-norm with nonconvex continuous functions, we reformulate a set of cardinality optimization problems in constraint-based modelling into a difference of convex functions. We implemented and numerically tested novel algorithms that approximately solve the reformulated problems using a sequence of convex programs. We applied these algorithms to various biochemical networks and demonstrate that our algorithms match or outperform existing related approaches. In particular, we illustrate the efficiency and practical utility of our algorithms for cardinality optimization problems that arise when extracting a model ready for thermodynamic flux balance analysis given a human metabolic reconstruction.Availability and implementationOpen source scripts to reproduce the results are here https://github.com/opencobra/COBRA.papers/2023_cardOpt with general purpose functions integrated within the COnstraint-Based Reconstruction and Analysis toolbox: https://github.com/opencobra/cobratoolbox.

Published: September 2023

Abstract

Summary
Bacterial Healthcare-Associated Infections (HAIs) are a major threat worldwide, which can be counteracted by establishing effective infection control measures, guided by constant surveillance and timely epidemiological investigations. Genomics is crucial in modern epidemiology but lacks standard methods and user-friendly software, accessible to users without a strong bioinformatics proficiency. To overcome these issues we developed P-DOR, a novel tool for rapid bacterial outbreak characterization. P-DOR accepts genome assemblies as input, it automatically selects a background of publicly available genomes using k-mer distances and adds it to the analysis dataset before inferring a Single-Nucleotide Polymorphism (SNP)-based phylogeny. Epidemiological clusters are identified considering the phylogenetic tree topology and SNP distances. By analyzing the SNP-distance distribution, the user can gauge the correct threshold. Patient metadata can be inputted as well, to provide a spatio-temporal representation of the outbreak. The entire pipeline is fast and scalable and can be also run on low-end computers.

Availability and implementation
P-DOR is implemented in Python3 and R and can be installed using conda environments. It is available from GitHub https://github.com/SteMIDIfactory/P-DOR under the GPL-3.0 license.
Primate coloration and colour vision: a comparative approach
Authors: Macdonald Robert X , Sheard Catherine , Howell Natasha , Caro Tim 
Published: September 2023

Abstract
Primates are remarkably colourful in comparison to other mammals. In particular, several species exhibit red–orange pelage or bright red skin, with the latter thought to signal status in intraspecific dominance interactions or to signal fertility. One potential driver of the interspecific diversity in red coloration is the primate visual system, which, uniquely among eutherian mammals, varies interspecifically and even between conspecifics in the ability to distinguish red and green (trichromatic colour vision). Previous comparative studies, however, have produced conflicting results regarding the proposed link between coloration and visual system. We employed an updated, sex-specific dataset of primate coloration and visual systems to re-examine the relationship between colour vision and red coloration across the entire order. With a few exceptions, increased colour visual ability is not significantly associated with the presence of red skin on the face or anogenital region, nor of red–orange pelage. We discuss possible reasons for the lack of colour–vision associations and suggest that dichromatic colour vision still facilitates effective signalling between conspecifics.

Published: September 2023

Abstract

Aims
Left ventricular systolic dysfunction (LSVD) is a heterogeneous condition with several factors influencing prognosis. Better phenotyping of asymptomatic individuals can inform preventative strategies. This study aims to explore the clinical phenotypes of LVSD in initially asymptomatic subjects and their association with clinical outcomes and cardiovascular abnormalities through multi-dimensional data clustering.

Methods and results
Clustering analysis was performed on 60 clinically available variables from 1563 UK Biobank participants without pre-existing heart failure (HF) and with left ventricular ejection fraction (LVEF) &lt; 50% on cardiovascular magnetic resonance (CMR) assessment. Risks of developing HF, other cardiovascular events, death, and a composite of major adverse cardiovascular events (MACE) associated with clusters were investigated. Cardiovascular imaging characteristics, not included in the clustering analysis, were also evaluated. Three distinct clusters were identified, differing considerably in lifestyle habits, cardiovascular risk factors, electrocardiographic parameters, and cardiometabolic profiles. A stepwise increase in risk profile was observed from Cluster 1 to Cluster 3, independent of traditional risk factors and LVEF. Compared with Cluster 1, the lowest risk subset, the risk of MACE ranged from 1.42 [95% confidence interval (CI): 1.03–1.96; P &lt; 0.05] for Cluster 2 to 1.72 (95% CI: 1.36–2.35; P &lt; 0.001) for Cluster 3. Cluster 3, the highest risk profile, had features of adverse cardiovascular imaging with the greatest LV re-modelling, myocardial dysfunction, and decrease in arterial compliance.

Conclusions
Clustering of clinical variables identified three distinct risk profiles and clinical trajectories of LVSD amongst initially asymptomatic subjects. Improved characterization may facilitate tailored interventions based on the LVSD sub-type and improve clinical outcomes.
