Published: August 2024

Abstract
Mn-based nitrides with antiperovskite structures have several properties that can be utilized for antiferromagnetic spintronics. Their magnetic properties depend on the structural quality, composition and doping of the cubic antiperovskite structure. Such nitride thin films are usually produced by reactive physical vapor deposition, where the deposition rate of N can only be controlled by the N2 gas flow. We show that the tuning of the N content can be optimized using low temperature resistivity measurements, which serve as an indicator of the degree of structural disorder. Several Mn3GaN

films were prepared by reactive magnetron sputtering under different N2 gas flows. Under optimized gas flow conditions, we obtain films that exhibit a metal-like temperature dependence of the resistivity, a vanishing logarithmic increase of the resistivity towards zero, the highest resistivity ratio, and a lattice contraction of 0.4% along the growth direction when heated above the Néel temperature

Abstract
Over the past two decades, nano additive lubricants have become essential in manufacturing as lubricating agents. Our study examines the impact of three process parameters—carbon nanotube (CNT) (volume concentration,%), sliding velocity (m/s), and applied load (N)—on the tribological performance of polyolester oil blended with carbon nanotubes. By employing the robust Taguchi L9 orthogonal array as the design of experiment, the current study made an attempt to identify the best combination of these three factors parameters to achieve the least coefficient of friction (COF) while the study also conducted ANOVA and multivariate linear regression to determine the significant factor that determines the least COF. For this study, POE oil and varying concentrations of CNTs (such as 0.05, 0.075 and 0.1 volume concentration%) were used. For this study, the characterization of the CNTs was performed using TEM, SEM and XRD methods while its stability was validated through Zeta potential value i.e., 0.075 volume concentration% CNT concentration achieved 35 mV zeta potential value. The Taguchi L9 orthogonal array outcomes found the least COF i.e., 0.0359 was achieved from 0.075 volume concentration % of CNT with a sliding speed of 3.6 m s−1 at 50 N load. The ANOVA outcomes confirmed the major contribution (91%) of the CNT concentration towards influencing the COF outcomes. The contour plots confirmed that optimal COF can be achieved when using 0.075 volume concentration% CNT with load ranged from 75 N to 125 N and sliding velocities between 1.2 m s−1 and 3.0 m s−1. The outcomes establish that when POE oil is supplemented with CNTs, it can achieve superior performance as the nanolubricant mitigates the coefficient of friction (COF), eventually enhancing the tribological performance. Future researchers can focus on employing Taguch-grey relational analysis, artificial intelligence and machine learning models to find the optimal process parameters for other lubricants and nanoadditives.
Efficient and novel multidomain feature analysis model with incremental optimizations for enhancing pediatric myelodysplastic syndrome detection
Authors: Srilakshmi K , D Venkata Lakshmi 
Published: August 2024

Abstract
Pediatric myelodysplastic syndromes (MDS) are complicated, thus early and accurate diagnosis is essential for treatment planning and patient care. Diagnostic processes often use discrete data domain analysis, which reduces accuracy and delays diagnosis. This work addresses these limitations by introducing an advanced Multi domain Feature Analysis Model (MFAM) enhanced with incremental optimizations to improve pediatric MDS detection. Traditional pediatric MDS diagnosis relies on subjective evaluations and limited data fusion, not modern computational methods. These constraints may reduce diagnosis accuracy and postpone action. The proposed MFAM integrates data from Clinical History, Physical Examination, Blood Cell Counts, Peripheral Blood Smear, Bone Marrow Aspiration and Biopsy, Cytogenetic Analysis, Flow Cytometry, Genetic Testing, Iron Studies, and Bone Marrow Cytology to overcome these challenges. The MFAM increases feature variance by fusing Bidirectional Long Short-Term Memory (BiLSTM) with Bidirectional Gated Recurrent Units (BiGRU). Deep Q Learning with Graph Recurrent Convolutional Neural Networks (DQGRCNN) boosts efficiency. Additionally, the model integrates the Vector Autoregressive Moving Average with Exogenous Inputs (VARMAX) to facilitate early prediction of paediatric MDS. These enhancements have resulted in significant improvements in the precision of paediatric MDS detection by 4.5%, accuracy by 3.5%, recall by 2.3%, Area Under the Curve (AUC) by 1.5%, and specificity by 2.4% while reducing diagnostic delays by 8.5%. Furthermore, the model enhances the precision of predictive analysis by 2.9%, accuracy by 3.5%, recall by 2.5%, AUC by 2.9%, specificity by 5.5%, and reduces delays in predictive analysis by 8.5%. The MFAM presented in this paper revolutionizes the diagnosis and treatment of paediatric MDS by efficiently combining diverse diagnostic data, employing advanced transformation and fusion techniques, and optimizing responses through DQGRCNN. The integration of VARMAX further enables early prediction of the disease. MFAM will enhance diagnostic precision, therapy start, and clinical outcomes for young MDS patients.

Published: August 2024

Abstract
The bond property of concrete is a key characteristic of concrete that affect the structural activity of reinforced concrete beams. Concrete produced from geopolymer has the prospect to replace concrete produced from ordinary Portland cement (OPC) for structural applications. Therefore, this research evaluates the bond behavior of metakaolin-calcium carbide residue (CCR)-based geopolymer concrete for use in in situ structural applications. Comparative studies were carried out on concrete made of geopolymer and OPC. The embedment lengths (5ϕ and 7ϕ) and reinforcing bar diameters (14 and 16 mm) were varied and the bonding activity of the different concrete types was studied. Additionally, the qualities of the concrete produced were assessed, including density, ultrasonic pulse velocity, and compressive and flexural strengths. Generally, the metakaolin-CCR-based geopolymer concrete samples had the best mechanical properties, followed by metakaolin-based geopolymer and OPC concrete, respectively. Bond activity enhanced when embedment length and diameter of reinforcement were reduced in all types of concrete. Thus, with a reinforcing bar diameter of 14 mm and an embedment length of 5ϕ, the average bond strength of the metakaolin-CCR-based geopolymer concrete was 14.3MPa, which was 18.87% and 105.46% higher than that of the metakaolin-based geopolymer and OPC concrete, respectively. Influenced by experimental conclusions, it can be established that the metakaolin-CCR-based geopolymer concrete has the capacity to be used in place of OPC concrete in bond applications where steel reinforcing bars are employed.
PSO based linear parameter varying-model predictive control for trajectory tracking of autonomous vehicles
Authors: Kedir Chala Abdulkadir , Abdissa Chala Merga 
Published: August 2024

Abstract
In this paper, Linear Parameter Varying-Model Predictive Control (LPV-MPC) for trajectory tracking for Autonomous Vehicles (AVs) is proposed. This method is based on the time-varying LPV is the form of the state space representation from the mathematical model of the vehicle. The LPV representation form which uses the dynamic model of the vehicle allows the incorporation of time-varying dynamics, providing a more accurate representation of the vehicle's behavior. The designed LPV-MPC controller for AVs is specifically designed to handle constraints in trajectory tracking. To enhance its performance, Particle Swarm Optimization (PSO) is employed as an optimization technique. PSO is used to tune the weighting matrices of the control parameters, optimizing the system response and improving trajectory tracking performance. To evaluate the effectiveness of the LPV-MPC system, extensive simulations are conducted and results are compared with Linear and Non-Linear MPCs. The main benefit of using the LPV-MPC method is its ability to calculate solutions almost as good as the non-linear MPC version yet significantly reducing the computational cost. The capability of the LPV-MPC controller as compared to the linear version is in its effective tracking, particularly for the non-linear reference trajectories.

Abstract
This chapter explores key cross-cutting themes that can influence well-being and well-becoming across the life-course, including: good work; our surroundings; money and resources; housing; education and skills; the food we eat; transport; and family, friends, and communities. These cross-cutting themes were chosen because they have been identified as protective factors and factors that can help individuals and society to maintain good health and well-being. The chapter examines some of the costs to society of health-harming and often addictive behaviours. Some examples of how economic evaluation has approached these areas to provide evidence of relative cost-effectiveness of interventions within and outside of the health sector are discussed. The chapter concludes with some curiosity questions for the reader to consider.
Cuba: Legal Reform and Updating Socialism
Authors: Bui Ngoc Son 
Published: August 2024

Abstract
This chapter explores legislative reform, administrative reform, judicial reform, and reform of the legal profession in Cuba since the late 1980s. In the late 1980s and early 1990s, Cuba carried out sporadic legal reforms to respond to the challenges of the Special Period. The Communist Party of Cuba’s adoption of the reform policy called Updating Socialism in 2011 and the state’s enactment of the new Constitution in 2019 have led to extensive and systematic legal reforms. Legal reform in Cuba is the political elite’s preservative project to update the institutional and substantive aspects of the socialist legal system while maintaining the principled commitments to the Cuban Revolution.
Seasonal and vertical patterns of water availability and variability determine plant reproductive phenology

Published: August 2024

Abstract

Background and Aims
Changing precipitation regimes can influence terrestrial plants and ecosystems. However, plant phenological responses to changing temporal patterns of precipitation and the underlying mechanisms are largely unclear. This study was conducted to explore the effects of seasonal precipitation redistribution on plant reproductive phenology in a temperate steppe.

Methods
A field experiment was undertaken with control (C), advanced (AP) and delayed (DP) growing-season precipitation peaks and the combination of AP and DP (ADP). Seven dominant plant species were selected and divided into two functional groups (early- vs. middle-flowering species, shallow- vs. deep-rooted species) to monitor reproductive phenology, including budding, flowering and fruiting dates and the reproductive duration for four growing seasons, 2015–2017 and 2022.

Key Results
The AP, but not DP treatment advanced the phenological (i.e. budding, flowering and fruiting) dates and lengthened the reproductive duration across the four growing seasons and seven monitored species. In addition, the phenological responses showed divergent patterns among different plant functional groups, which could be attributed to shifts in soil moisture and its variability in different months and soil depths. Moreover, species with lengthened reproductive duration increased phenological overlap with other species, which could have a negative impact on their dominance under the AP treatment.

Conclusions
Our findings reveal that changing precipitation seasonality could have considerable impacts on plant phenology by affecting soil water availability and variability. Incorporating these two factors simultaneously in the phenology models will help us to understand the response of plant phenology under intensified changing precipitation scenarios. In addition, the observations of decreased dominance for the species with lengthened reproductive duration suggest that changing reproductive phenology can have a potential to affect community composition in grasslands under global change.
Evolution of the basic helix–loop–helix transcription factor SPATULA and its role in gynoecium development

Published: August 2024

Abstract

Background and Aims
SPATULA (SPT) encodes a basic helix–loop–helix transcription factor in Arabidopsis thaliana that functions in the development of the style, stigma and replum tissues, all of which arise from the carpel margin meristem of the gynoecium. Here we use a comparative approach to investigate the evolutionary history of SPT and identify changes that potentially contributed to its role in gynoecium development.

Methods
We investigate SPT’s molecular and functional evolution using phylogenetic reconstruction, yeast two-hybrid analyses of protein–protein interactions, microarray-based analyses of protein–DNA interactions, plant transformation assays, RNA in situ hybridization, and in silico analyses of promoter sequences.

Key results
We demonstrate the SPT lineage to have arisen at the base of euphyllophytes from a clade of potentially light-regulated transcription factors through gene duplication followed by the loss of an active phytochrome binding (APB) domain. We also clarify the more recent evolutionary history of SPT and its paralogue ALCATRAZ (ALC), which appear to have arisen through a large-scale duplication within Brassicales. We find that SPT orthologues from diverse groups of seed plants share strikingly similar capacities for protein–protein and protein–DNA interactions, and that SPT coding regions from a wide taxonomic range of plants are able to complement loss-of-function spt mutations in transgenic Arabidopsis. However, the expression pattern of SPT appears to have evolved significantly within angiosperms, and we identify structural changes in SPT’s promoter region that correlate with the acquisition of high expression levels in tissues arising from the carpel margin meristem in Brassicaceae.

Conclusions
We conclude that changes in SPT’s expression pattern made a major contribution to the evolution of its developmental role in the gynoecium of Brassicaceae. By contrast, the main biochemical capacities of SPT, as well as many of its immediate transcriptional targets, appear to have been conserved at least since the base of living angiosperms.
The Combined Bra-Line Back Lift Latissimus Flap (BLBL-LAT Flap) for Aesthetic Breast Reconstruction and Simultaneous Back Contouring
Authors: Li Wai-Yee 
Published: August 2024

Abstract

Background
The latissimus dorsi pedicled (LAT) flap has been a workhorse flap for breast reconstruction for many decades. The asymmetric back scar has been a major source of complaint. In patients with excess back adiposity, we can utilize the skin paddle harvest to improve back contour. We combined the principles of the aesthetic bra-line back lift with the LAT flap to provide simultaneous improvement of both posterior upper trunk adiposity and skin excess, which together form “back rolls,” with a concealed scar.

Objectives
The objective was to establish a new surgical technique of combined bra-line back lift with latissimus dorsi flap (BLBL-LAT flap) for aesthetic breast reconstruction.

Methods
This was an IRB-approved retrospective single-surgeon study performed in a national cancer center. We included patients undergoing breast reconstruction with the combined BLBL-LAT flap between 2015 and 2023, with a minimum of 6 months of follow-up.

Results
A total of 106 female patients underwent 110 breast reconstructions with the BLBL-LAT flap. Seventy-five percent of patients had prosthesis placement and 25% of patients were 100% autologous. Complication rates were low: 4 of 106 patients (3.8%) had seroma, needing surgery. Of the 78 reconstructions with implants or tissue expanders, 3 (3.8%) had a periprosthetic infection. One (&lt;1%) patient had partial flap loss, and no patients had complete flap loss. Four patients had bilateral BLBL-LAT flap reconstruction. Two unilateral breast reconstruction patients came back for successful symmetrizing of the bra-line back lift (without LAT flap breast reconstruction).

Conclusions
The BLBL-LAT flap allows breast reconstruction and simultaneous improvement of back contour, leaving a scar that can be concealed in a bra. This 2-for-1 procedure is of particular benefit to patients with a high BMI, who often have unwanted excess adiposity and laxity of the back. Because this patient population is at high risk for free tissue transfer, we propose that the BLBL-LAT flap be considered the first-line method of autologous breast reconstruction in higher BMI patients.

A case of superior mesenteric artery stenting for small intestinal ischaemia caused by superior mesenteric artery invasion of pancreatic cancer
Authors: Kuwamura Hiroshi , Suyama Yohsuke , Enjoji Yasuhiro , Einama Takahiro , Kishi Yoji , Shinmoto Hiroshi 
Published: August 2024

Abstract
Superior mesenteric artery (SMA) invasion by a malignant tumour is a serious condition leading to intestinal ischaemia. Although SMA stenting has been reported to be useful for SMA dissection and stenosis caused by atherosclerotic plaque, SMA stenting for stenosis caused by malignant tumour invasion is rarely reported and uncertain. A 75-year-old woman presented intestinal ulcer and melena caused by SMA invasion of unresectable pancreatic cancer. The bare metal stent was implanted for the vessel stenosis, and a small intestinal ulcer was markedly improved after stenting. However, one and a half months after stenting the stent was occluded and a thrombectomy was performed. After thrombectomy, residual stenosis caused by tumour invasion was observed in the stent. The patient suddenly died 2 days after thrombectomy before additional covered stenting for residual stenosis. Stent implantation may be a treatment option for intestinal ischaemia caused by vessel invasion of malignant tumours. On the other hand, re-stenosis of the stent due to tumour ingrowth is a problem, and covered stenting is considered for long-term stent patency.

Abstract
Monogenic diseases are well-suited paradigms for the causal analysis of disease-driving molecular patterns. Spinal muscular atrophy (SMA) is one such monogenic model, caused by mutation or deletion of the survival of motor neuron 1 (SMN1) gene. Although several functions of the SMN protein have been studied, single functions and pathways alone do not allow the identification of crucial disease-driving molecules.
Here, we analysed the systemic characteristics of SMA, using proteomics, phosphoproteomics, translatomics and interactomics, from two mouse models with different disease severities and genetics.
This systems approach revealed subnetworks and proteins characterizing commonalities and differences of both models. To link the identified molecular networks with the disease-causing SMN protein, we combined SMN-interactome data with both proteomes, creating a comprehensive representation of SMA. By this approach, disease hubs and bottlenecks between SMN and downstream pathways could be identified.
Linking a disease-causing molecule with widespread molecular dysregulations via multiomics is a concept for analyses of monogenic diseases.

Abstract
This article implements maximum power point tracking (MPPT) based on the improved hill-climbing algorithm for photovoltaic (PV) systems feeding resistive loads. A direct current-to-direct current boost converter is inserted between the PV system and the load to achieve matching. The converter is managed using MPPT based on the hill-climbing algorithm. The objective of this paper is to optimize the code program to achieve the best compromise between accuracy and rapidity by implementing this algorithm using a microcontroller. Two PV systems are tested under identical meteorological conditions. In the first, an improved hill-climbing MPPT controller is used whereas, in the second, the conventional version is employed. The experimental results obtained show a significant enhancement in terms of speed for the improved algorithm with a value of 0.4 s for the response time and 3% for the oscillation power; those values remain satisfactory in terms of precision of the algorithm compared with the conventional system studied and the compared algorithm from the literature.
Morphological effect of TiO2 nanoparticles in TiO2/g-C3N4 heterojunctions on photocatalytic dye degradation

Published: August 2024

Abstract
The effects of TiO2 nanoparticle (NP) morphology on the photocatalytic activity of physically assembled TiO2 NP/g-C3N4 heterojunctions (TCNPHY) were investigated. Spherical, spindle, and cubic TiO2 NPs were synthesized and separately supported on g-C3N4 nanosheets to form physically assembled TCNPHY catalysts. The photocatalytic activity for methylene blue degradation observed for TCNPHY with the cubic TiO2 NPs supported higher light absorption and a lower recombination rate; therefore, this was an adequate catalyst for the construction of catalytically active heterojunctions. The cubic TiO2 TCNPHY exhibited a degradation rate that was 2.2 times higher than that for the g-C3N4 nanosheets alone.
