Authors: Barbosa I M , Ferreira M G V , Júnior M F C 
Published: June 2023

Abstract
This article presents the data acquisition, exploratory data analysis, model training, evaluation, and use of hyperparameters in a machine learning model that will be used to predict telemetry data from the Amazonia-1 satellite. The Amazonia-1 satellite was launched in 2021, it uses the Multi-Mission Platform as a service module and has a Wide Field Imager imaging camera. Its power subsystem has 715 telemetries with distinct data types that will be used as dependent and independent variables. The amount of telemetry data generated daily is large, making manual analysis of this data unfeasible. The ensemble XGBoost machine learning algorithm is used to predict the values of the dependent variable D008 “Battery Module 1 Voltage” that belongs to the electric power subsystem. For the evaluation and performance Mean Absolute Error (MAE), Root Mean Square Error (RMSE), and R2 are used. The final learning model resulted in the coefficient of determination (R2) with 99.99%, MAE of 0.005749, and RMSE of 0.007727. After the cross-validation step, RMSE reached 0.006888. The execution time was 57 minutes and 32 seconds. Based on these numbers, we can consider that the machine learning model built reached a good result, especially when used with cross-validation.
New Operational Load Monitoring Approach Using Digital Image Correlation and Image Classification Networks
Authors: Mucha W , Kokot G , Viana J C , Nunes J P 
Published: June 2023

Abstract
The following paper presents a novel approach that can be applied to Operational Load Monitoring and Structural Health Monitoring processes. The approach is based on artificial intelligence (AI) and digital image correlation (DIC) techniques. DIC is an optical method that allows measuring full-field structural displacements and strains. In the presented approach only a relatively small fragment of the material’s surface is monitored by DIC. The obtained partial image of strains or displacements is then processed by a carefully trained AI model, an image classification network, able to predict the state of whole structure (e.g. materials stresses, potential loss of material continuity). The assumption is that all possible load cases and states of the monitored structure can be identified and simulated, so the data obtained from simulations can then be used to train the image classification network. A numerical example is presented as proof of the presented concept. A modern lightweight aerostructure in the form of a hat-stiffened composite panel was used as monitored structure in the presented example and its Operational Load Monitoring was performed based on a relatively small fragment of normal strains map. The reference maps to train the network were simulated numerically. The prediction model estimates the Tsai-Wu failure criterion value for the whole composite material. The obtained accuracy of predictions proved the effectiveness and efficiency of the proposed approach.

Abstract
Lateral forces (wind, seismic) generated in RC buildings are major design criteria against structural collapse. Shear walls offer effective ways to provide resistance against such lateral loads. The present study investigates the drift and defection control of RC symmetrical buildings by providing core and corner shear walls. Different limiting criteria were determined in four seismic zones (Zone-1 to Zone-4) in Bangladesh, based on aspect ratio and proposed breadth to length ratio (B/L ratio). Equivalent Static Analysis in ETABS V.2016 was used to analyze three distinct breadth-to-length ratios – 1, 0.7, and 0.4 for each zone without shear wall and with both core and corner shear walls. Results reveal that corner shear walls act efficiently compared to core walls to resist lateral loads, drift, and deflection. A descending failure pattern was observed from lower to higher seismic zones for the corresponding breadth to length ratios (B/L).

Authors: Teh T W , Yap Y Q 
Published: June 2023

Abstract
Modelling of early curing stage of a bridge pier foundation pile cap of 4.5m thick, to be constructed at Betong division, Sarawak was carried out to verify scheme of water-cooling pipe can meet temperature specifications in which concrete must not reach a peak temperature of 70°C, and differential temperature at core and surface of concrete must not exceed 25°C. Modelling was carried out using transient heat transfer finite element analysis programme and by treating the pile cap as a concrete solid body, assuming no heat generation nor thermal conductivity of reinforcement bars. The result shows that the cooling scheme is feasible to meet temperature limitations of the specifications.

Published: June 2023

Abstract
NEWAGE is the experiment of direction-sensitive dark matter search using low pressure
gaseous TPC with micro pattern strip readout (μ-PIC). It allows to measure the distribution
of angles of WIMP-nuclear recoil by track reconstruction, and it allows a positive signature of
dark matter. In recent years, large size (∼1 m3) TPC filled with SF6 gas, which is
so called “negative-ion gas”, is under development. A TPC with negative ions is a novel technology
for the measurement of absolute position of drift direction coordinates in a self-triggering
system. The determination of the absolute track position allows to discriminate nuclear recoils
in the target gas volume from alpha-rays from the detector surface, which is one of the background
sources. Furthermore, diffusion of drifting negative ions is expected to be lower than that of
nominal electron drift, which allows to improve angular resolution. This presentation reports the
status of the development of negative-ion gaseous TPC with a prototype small chamber. In
addition, we started to develop O(100) μm pitch gaseous TPC detector with pixel type readout
system to achieve reconstruction of short track nuclear recoils with good angular resolution. It
enables to explore lower mass region of direction-sensitive dark matter searches. We also report
about the status of the pixel detector development.

Authors: Lachynov S.B. , Vinokurov N.A. 
Published: June 2023

Abstract
Generation of short electron bunches with high peak current is of great importance for different research and technological applications. Such generation requires a special bunching magnetic system. This paper describes a new scheme of a magnetic buncher for relativistic electrons. The buncher provides a strong dependence of the time of flight on the particle energy and thus is capable to bunch relatively long bunches to short ones.
Picometer-precision few-tilt ptychotomography of 2D materials

Published: June 2023

Abstract
From ripples to defects, edges and grain boundaries, the 3D atomic structure of 2D materials is critical to their properties. However the damage inflicted by conventional 3D analysis precludes its use with fragile 2D materials, particularly for the analysis of local defects. Here we dramatically increase the potential for precise local 3D atomic structure analysis of 2D materials, with both greatly improved dose efficiency and sensitivity to light elements. We demonstrate light atoms can now be located in complex 2D materials with picometer precision at doses 30 times lower than previously possible. Moreover we demonstrate this using WS2, in which the light atoms are practically invisible to conventional methods at low doses. The key advance is combining the concept of few tilt tomography with highly dose efficient ptychography in scanning transmission electron microscopy. We further demonstrate the method experimentally with the even more challenging and newly discovered 2D CuI, leveraging a new extremely high temporal resolution camera.
Computing strain-dependent energy transfer from quantum dots to 2D materials
Authors: Şimşek Esra , Aslan Burak 
Published: June 2023

Abstract
Near-field interaction between the monolayers of two-dimensional (2D) materials has been recently investigated. Another branch under investigation has been the interaction between 2D materials and zero-dimensional (0D) nanostructures including quantum dots (QDs) and metal nanoparticles. In this work, we take one more step to engineering the interaction between those systems. We probe the effect of mechanical strain on the non-radiative energy transfer (NRET) rate from a 0D material, ZnCdSe/ZnSe QD, to a 2D material, monolayer (1L) WS2. It is known that the mechanical strain causes large shifts to the exciton energies in 1L WS2. As a result, our calculations show that strain can tune the NRET rate by engineering the overlap between the emission spectrum of ZnCdSe/ZnSe QD and the exciton resonances of 1L WS2.
Metagenomic insights into the functional microbial diversity of the lower stretch of the River Ganga: mapping antibiotic and metal resistance genes
Authors: Ghosh Anwesha , Yash  , Kumar Chakresh , Bhadury Punyasloke 
Published: June 2023

Abstract
The banks of the lower stretch of River Ganga are home to several towns and megapolis representing high density of human population. A stretch of 50 km represented by prefixed stations of the lower part of Ganga (Ganga Environmental Time Series- GETS) was monitored spatiotemporally using eDNA metagenome-based Nanopore sequencing to elucidate structure of microbial communities along with mapping of antibiotic-resistant genes (ARGs), metal resistance genes (MRGs) and mobile genetic elements (MGEs). Besides, in situ environmental parameters, concentration of dissolved nutrients, metals and metalloids were measured. The concentration of dissolved oxygen ranged from 3.4–6.2 mg l−1, indicating deteriorating water quality corresponding to high population density. Dissolved nitrate concentrations were higher in some stations reflecting direct release of untreated municipal sewage into the river. In particular, concentration of metals such as Cd (2.34–38.52 ppb) and metalloids such as As (0–218.7 ppb) were found to be alarmingly high in surface water. Gammaproteobacteria was encountered ubiquitously while rare bacterioplankton represented by eleven classes showed site specificity. Several genes belonging to ARGs were identified and multidrug resistance genes (MDR) were found in all the studied stations exhibiting high abundance. The ‘hotspots’ of ARGs were widespread, possibly owing to rampant usage of personal health care products that may have contributed to observed ARG abundances. High abundance of MRGs comprising arsenic (∼12%) and copper (∼12%) were also identified showing strong correlations with the abundance of ARGs. Correlation and network analysis revealed the potential role of MGEs in the dissemination of ARGs. ANOSIM and cluster analyses supported patchy distribution patterns of microbial communities. The RDA plot showed possible influences of environmental parameters in shaping the microbial community structure and towards dissemination of functional genes such as ARGs and MRGs in the lower stretch of the River Ganga.
Logical Conventionalism and the Adoption Problem
Authors: Hattiangadi Anandi 
Published: June 2023

AbstractIn this paper, I take issue with a core commitment of logical conventionalism: that we impose a logic on ourselves by adopting general linguistic conventions governing our use of logical terms, thereby determining the meanings of the logical constants and which of our inferences are valid. Drawing on Kripke’s ‘adoption problem’, I argue that general logical principles cannot be adopted, either explicitly or implicitly. I go on to argue that the meanings of our logical terms, and the validity of our inferences, cannot depend on our adoption of logico-linguistic conventions.
Leukocyte–endothelial interaction in CKD
Authors: Sarakpi Tamim , Mesic Armir , Speer Thimoteus 
Published: June 2023

ABSTRACT
Chronic kidney disease (CKD) represents an independent risk factor for cardiovascular diseases (CVD). Accordingly, CKD patients show a substantial increased risk of cardiovascular mortality. Inflammation represents an important link between CKD and CVD. The interaction between endothelial cells and effector cells of the innate immune system plays a central role in the development and progression of inflammation. Vascular injury causes endothelial dysfunction, leading to augmented oxidative stress, increased expression of leukocyte adhesion molecules and chronic inflammation. CKD induces numerous metabolic changes, creating a uremic milieu resulting in the accumulation of various uremic toxins. These toxins lead to vascular injury, endothelial dysfunction and activation of the innate immune system. Recent studies describe CKD-dependent changes in monocytes that promote endothelial dysfunction and thus CKD progression and CKD-associated CVD. The NLR family pyrin domain containing 3–interleukin-1β–interleukin-6 (NLRP3–IL-1β–IL-6) signaling pathway plays a pivotal role in the development and progression of CVD and CKD alike. Several clinical trials are investigating targeted inhibition of this pathway indicating that anti-inflammatory therapeutic strategies may emerge as novel approaches in patients at high cardiovascular risk and nonresolving inflammation. CKD patients in particular would benefit from targeted anti-inflammatory therapy, since conventional therapeutic regimens have limited efficacy in this population.

Published: June 2023

Abstract

Aims
To investigate the association of iatrogenic cardiac tamponades as a complication of invasive electrophysiology procedures (EPs) and mortality as well as serious cardiovascular events in a nationwide patient cohort during long-term follow-up.

Methods
From the Swedish Catheter Ablation Registry between 2005 and 2019, a total of 58 770 invasive EPs in 44 497 patients were analysed. From this, all patients with periprocedural cardiac tamponades related to invasive EPs were identified (n = 200; tamponade group) and matched (1:2 ratio) to a control group (n = 400). Over a follow-up of 5 years, the composite primary endpoint—death from any cause, acute myocardial infarction, transitory ischaemic attack (TIA)/stroke, and hospitalization for heart failure—revealed no statistically significant association with cardiac tamponade [hazard ratio (HR) 1.22 (95% CI, 0.79–1.88)]. All single components of the primary endpoint as well as cardiovascular death revealed no statistically significant association with cardiac tamponade. Cardiac tamponade was associated with a significantly higher risk with hospitalization for pericarditis [HR 20.67 (95% CI, 6.32–67.60)].

Conclusion
In this nationwide cohort of patients undergoing invasive EPs, iatrogenic cardiac tamponade was associated with an increased risk of hospitalization for pericarditis during the first months after the index procedure. In the long-term, however, cardiac tamponade revealed no significant association with mortality or other serious cardiovascular events.
The effects of Cyclina sinensis bioturbation on alkaline phosphatase and total microbial hydrolytic activities in marine clam–shrimp integrated ponds
Authors: Nicholaus Regan , Lukwambe Betina , Zheng Zhongming 
Published: June 2023

Abstract
This study investigated the influence of Venus clam Cyclina sinensis bioturbation activities on the total benthic microbial and phosphatase activities and selected sediment properties: total phosphorus (TP), total organic nitrogen (TON), and total organic carbon (TOC) in aquaculture ponds. Sediments samples from clam-shrimp integrated pond and non-clam integrated pond were sampled for the study, in which sediment microbial activity (MBA) and alkaline phosphatase activity (APA), sediment organic contents (TP, TON, TOC, TOM) and water quality parameter (dissolved oxygen, temperature, pH, and moisture content) were analyzed. The p-nitrophenyl phosphate disodium (p-NPP) and fluorescein diacetate (FDA) were adopted to measure APA and MBA, respectively. Results indicated that MBA and alkaline phosphatase activity (APA) in sediments significantly increased in the pond cultured with clam/shrimp compared to a non-clam cultured pond. Phosphorus concentration increased significantly and varied among months (P &lt; 0.05), implying an increased phosphate mineralization in the sediments. The concentrations of TON and TOC did not differ significantly among months and with the treatments (P &gt; 0.05), implying increased TON mineralization. Correlation analyses showed that there was a positive correlation with the total MBA, APA, phosphorus concentration, and organic matter content within the sediments bioturbated by the Venus clam. The results suggest that, the Venus clam sediment reworking mechanisms influenced the sediment-microbial and APA activities and mineralization, thereby affecting the pond alkaline phosphatase enzyme-related activities.

Published: June 2023

Abstract

OBJECTIVES
This case series aimed to determine the feasibility of simultaneous modified Ravitch and David procedure for Marfan syndrome patients with pectus excavatum and annuloaortic ectasia.

METHODS
Between March 2014 and December 2019, seven consecutive patients underwent simultaneous surgery of modified Ravitch and David procedure for pectus excavatum and annuloaortic ectasia. The completion of cardiac surgery and sternal closure were followed by the modified Ravitch procedure. The bilateral fourth to seventh costal cartilages were resected, the sternal body partially wedge resected, and the sternum raised anteriorly with re-suture. An oblique incision was performed on bilateral third costal cartilages, and they were fixed on top of each other, with the medial end superior and the lateral end inferior. The sternum was raised anteriorly, bypassing the fourth to seventh rib ends through the back of the sternum with threads. The feasibility and safety of the procedure were assessed through a retrospective review of the patients’ clinical charts.

RESULTS
The total sample had a median age of 28 years, and comprised five males and two females. There was a significant difference in the preoperative and postoperative median Haller index, which were 6.8 and 3.9, respectively. All patients were discharged without serious complications, and there was no significant recurrence of pectus excavatum at 35–92 months postoperatively.

CONCLUSIONS
The results of our case series suggest the feasibility of one-stage surgery for pectus excavatum combined with cardiac surgery using the modified Ravitch procedure. Future efforts should be tailored for more uneventful postoperative clinical courses.

Abstract
To improve the usage rate of district heat supply network and solve the frost problem in solar-air heat pumps, this study used TRNSYS to construct a new solar-air source heat pump heating composite system that uses waste heat from the district heat supply network. The impact of the waste heat recovery device on the heating performance of the new composite system was analysed, and the economic and environmental performance of the composite system was compared with other heating systems. During a typical day, the average coefficient of performance of air source heat pumps (COP) of the composite system increased by 13% and the power consumption of the system decreased by 35.9%. Throughout the heating season, the power consumption of the composite system was 13.59% higher than that of traditional systems, and system coefficient of performance (SCOP) was 15.89% lower than traditional systems. Based on economic analysis, the relative operating costs of the composite system, coal-fired boiler, gas-fired boiler, oil-fired boiler and combined heat and power (CHP) are 1, 1.19, 2.33, 5.56 and 0.85, respectively. The operating cost of the composite heat source system is only 17.43% higher than that of CHP and lower than the other three heating systems. Quantitative evaluations of the environmental friendliness of these systems were conducted using the fuzzy analysis mathematical method. The evaluation results were 9.62, 5.89, 15.05, 9.10 and 6.79, respectively. It was found that the composite system is second only to the gas-fired boiler in terms of environmental friendliness and is 38.9% higher than the coal-fired boiler and 29.5% higher than the CHP.
Insignificant Difference in Early Post-injury Gene Expression Between Patients with Burns Only and Those with Inhalation Injury: A Bioinformatics Analysis

Published: June 2023

Abstract
Airway obstruction is fatal but common among burn patients in the early period after inhalation injury, during which most tracheotomies are performed within 48 h post-injury. Inflammation is common in laryngoscopy; however, the related gene expression has rarely been studied. In this study, we obtained the data of healthy control and patient samples collected within 8–48 hours post-injury from the Gene Expression Omnibus database and classified them into 10 inhalation-injury patients, 6 burn-only, and 10 healthy controls. Differential gene expression was identified between the patient groups; however, principal component analysis and cluster analysis indicated a similarity between groups. Furthermore, enrichment analysis, Kyoto Encyclopedia of Genes and Genomes, and gene set enrichment analyses showed no significant differences in immune regulation and cell adjustment between the patient groups; but differences were shown when comparing either patient group to the healthy control group, including prominent regulation in inflammatory cells, infection, and cell adjustment. Thus, the gene expression in inhalation injury and burn-only patients does not significantly differ in the early period after injury, especially in inflammation, indicating the absence of specific diagnostic markers or anti-inflammatory treatment in inhalation injury patients, with the potential to identify more subtle differences. Further research is warranted.
