Authors: Lloyd Max J. , Wills Daniel J. , Crowley James D. , Wang Tian , Tan Christopher J. , Walsh William R. 
Published: January 2023

AbstractObjective The aim of this study was to determine the effect of a unicortical defect at either the mid-diaphysis (MD) or distal metaphysis (DM) on the torsional properties of tibiae in an in vitro rabbit model, and to further examine optimal distal jig pin position for the canine tibial plateau levelling osteotomy (TPLO) procedure.Study Design Thirty-eight tibiae from 19 skeletally mature female New Zealand White rabbits were assigned to one of three groups; Group 1: intact, Group 2: MD defect and Group 3: DM defect. Defects were created using a 1.6 mm Ellis pin. Pure torsion was applied to each sample and peak torque and angular displacement recorded.Results All tibiae fractured in a spiral configuration. Fracture lines involved the defect in 33% of the MD samples and 0% of the DM samples. No differences were detected for peak torque and stiffness between groups. However, energy (mean ± standard deviation) was significantly reduced (p = 0.028) in the MD group (0.18 ± 0.07) relative to the intact tibia group (0.31 ± 0.14). Angle was also significantly reduced (p = 0.040) in the MD group (0.17 ± 0.05) compared with the intact group (0.23 ± 0.07). Placement of a DM defect had no significant effect on mechanical properties of the rabbit tibiae.Conclusion Defects placed in the MD significantly reduced energy and angle in comparison to intact samples. No significant difference in peak torque or stiffness was observed between groups. If canine tibiae were similarly affected, our findings suggest jig pin placement in the DM to have a lesser effect on the torsional properties of the tibiae.

The role of social capital in subjective quality of life
Authors: Imbulana Arachchi Janaki , Managi Shunsuke 
Published: January 2023

AbstractThis paper investigates the role of social capital (SC) in subjective quality of life to address the limitations of existing observable indicators as evidence for public policy. We use a large-scale survey of 100,956 respondents across 37 countries, including both developed and less developed countries. The empirical results suggest that higher SC is more strongly associated with better subjective health and higher satisfaction in low-income countries than in high-income countries. Moreover, while low-income countries show a lower level of perceived economic inequality at the community level with higher SC, high-income countries present a higher level. We further find that higher levels of educational attainment increase the perception of economic inequality and that this impact decreases with SC. Enhancing SC may lead to improved quality of life in most low-income countries, and lifestyle and cultural factors also play a crucial role. These findings indicate that noneconomic factors underpin better lives, and further research is needed to address the social aspects of life.

Published: January 2023

Background Lightning is the most common origin of natural fires, being strongly linked to specific synoptic conditions associated with atmospheric instability, such as dry thunderstorms; dry fuels are required for ignition to take place and for subsequent propagation. Aims The aim was to predict the daily probability of ignition by exploiting a large dataset of lightning and fire data to anticipate ignition over the entire Iberian Peninsula. Methods We trained and tested a machine learning model using lightning strikes (>17 million) in the period 2009–2015. For each lightning strike, we extracted information relating to fuel condition, structural features of vegetation, topography, and the specific characteristics of the strikes (polarity, intensity and flash density). Key results Naturally triggered ignitions are typically initiated at higher elevations (above 1000 m above sea level) under conditions of low dead fuel moisture (<10–13%) and moderate live moisture content (Drought Code > 300). Negative-polarity lightning strikes (−10 kA) appear to trigger fires more frequently. Conclusions and implications Our approach was able to provide ignition forecasts at multiple temporal and spatial scales, thus enhancing forest fire risk assessment systems.

Physical inactivity is a scourge to human health, promoting metabolic disease and muscle wasting. Interestingly, multiple ecological niches have relaxed investment into physical activity, providing an evolutionary perspective into the effect of adaptive physical inactivity on tissue homeostasis. One such example, the Mexican cavefish
Astyanax mexicanus,
has lost moderate-to-vigorous activity following cave colonization, reaching basal swim speeds ~3.7-fold slower than their river-dwelling counterpart. This change in behavior is accompanied by a marked shift in body composition, decreasing total muscle mass and increasing fat mass. This shift persisted at the single muscle fiber level via increased lipid and sugar accumulation at the expense of myofibrillar volume. Transcriptomic analysis of laboratory-reared and wild-caught cavefish indicated that this shift is driven by increased expression of
pparγ
—the master regulator of adipogenesis—with a simultaneous decrease in fast myosin heavy chain expression. Ex vivo and in vivo analysis confirmed that these investment strategies come with a functional trade-off, decreasing cavefish muscle fiber shortening velocity, time to maximal force, and ultimately maximal swimming speed. Despite this, cavefish displayed a striking degree of muscular endurance, reaching maximal swim speeds ~3.5-fold faster than their basal swim speeds. Multi-omic analysis suggested metabolic reprogramming, specifically phosphorylation of Pgm1-Threonine 19, as a key component enhancing cavefish glycogen metabolism and sustained muscle contraction. Collectively, we reveal broad skeletal muscle changes following cave colonization, displaying an adaptive skeletal muscle phenotype reminiscent to mammalian disuse and high-fat models while simultaneously maintaining a unique capacity for sustained muscle contraction via enhanced glycogen metabolism.

Embryo implantation, a crucial step in human reproduction, is tightly controlled by estrogen and progesterone (P

-methyladenosine (m

signaling. Conditional deletion of methyltransferase-like 3 (

A writer METTL3, in the female reproductive tract using a Cre mouse line with
Pgr
promoter (
Pgr-Cre
) resulted in complete implantation failure due to pre-implantation embryo loss and defective uterine receptivity. Moreover, the uterus of

Mettl3
deletion was accompanied by a marked decrease in PGR protein expression. Mechanistically, we found that

Macrophage migration inhibitory factor (MIF) is a multifaced protein that plays important roles in multiple inflammatory conditions. However, the role of MIF in endothelial cell (EC) death under inflammatory condition remains largely unknown. Here we show that MIF actively promotes receptor-interacting protein kinase 1 (RIPK1)-mediated cell death under oxygen-glucose deprivation condition. MIF expression is induced by surgical trauma in peripheral myeloid cells both in perioperative humans and mice. We demonstrate that MIF-loaded myeloid cells induced by peripheral surgery adhere to the brain ECs after distal middle cerebral artery occlusion (dMCAO) and exacerbate the blood–brain barrier (BBB) disruption. Genetic depletion of myeloid-derived MIF in perioperative ischemic stroke (PIS) mice with MCAO following a surgical insult leads to significant reduction in ECs apoptosis and necroptosis and the associated BBB disruption. The adoptive transfer of peripheral blood mononuclear cells (PBMC) from surgical MIF

mice to wild-type (WT) MCAO mice also shows reduced ECs apoptosis and necroptosis compared to the transfer of PBMC from surgical MIF

f  l/f  l

mice to MCAO recipients. The genetic inhibition of RIPK1 also attenuates BBB disruption and ECs death compared to that of WT mice in PIS. The administration of MIF inhibitor (ISO-1) and RIPK1 inhibitor (Nec-1s) can both reduce the brain EC death and neurological deficits following PIS. We conclude that myeloid-derived MIF promotes ECs apoptosis and necroptosis through RIPK1 kinase-dependent pathway. The above findings may provide insights into the mechanism as how peripheral inflammation promotes the pathology in central nervous system.

Published: January 2023

Abstract
Experimental campaigns were undertaken to understand and improve the coupling efficiency of Radio frequency (RF) power into the plasma in three accelerator-based ion sources. Different matching circuit and mechanical engineering setups were used and the network resistance calculated. The efficiency was then measured for a range of RF frequencies and input gas flows. Coupling efficiencies of around 60% were measured in setups using RF-coils mounted external to the plasma chamber. The efficiency is improved to 80% when the coil is immersed in the plasma, allowing closer coupling. As well as the coil geometry, the isolation transformer required for beam production contributes to the overall losses.
Luminescence characteristics of Dy3+ doped sodium alumina borate glass: Role of silver

Published: January 2023

Abstract
Metallic nanoparticle (NP) doped glasses have been studied as promising candidates for various technological applications due to their ability to improve the luminescence properties of rare earth ions. In this work, Dy2O3 and Ag2O co-doped sodium alumina borate glasses were synthesized by conventional melt-quenching technique. Raman analysis verified the existence of [BO3] and [BO4] groups with B–O stretching vibrations in the prepared glasses. Transmission electron microscope images confirmed the presence of spherical Ag NPs, whose average diameter is about 7.60 nm, in H-0.5Dy1Ag glass matrix. The optical and luminescence properties were investigated according to Ag concentrations. The negative value of the bonding parameters, calculated from the absorption spectra, indicates the ionic nature between the Dy3+ ions and its surrounding ligands. In order to determine the nature of the Dy-O bond and the symmetry around the Dy3+ ion environment, Judd–Ofelt intensity parameters (Ω
λ, λ = 2, 4, 6) were obtained from the absorption spectra. The luminescence spectra obtained under 350 nm excitation exhibits four emission bands at 481 (4F9/2→6H15/2), 572 (4F9/2→6H13/2), 662 (4F9/2→6H11/2), and 750 (4F9/2→6H9/2) nm. The intensity of emission spectra increases with Ag2O content until 1.0 wt% in H-0.5Dy-yAg glasses and then decreases due to the back-energy transfer (ET) from Dy3+ to Ag+. The ET mechanism from Ag+ to Dy3+ ion for H-1Ag-xDy glasses were investigated through Forster-Dexter’s theory and were found to be quadrupole-quadrupole type. The various radiative properties were calculated by using Judd-Ofelt intensity parameters and emission spectra. It was found that the 572 nm emission band, located in the yellow region, has higher radiative parameters. As a function of Ag concentration, the Y/B values, Commission Internationale d’Eclairage (CIE) chromaticity coordinates (x,y) and correlated color temperatures (CCT) were evaluated. The CIE chromaticity coordinates and CCT values of all glasses are located in the white light region. The decay time values of 1S0→3D1 transition of Ag+ ions and 4F9/2→6H13/2 transition of Dy3+ ions confirm the ET from Ag+ to Dy3+ ions. Overall, the present study indicates that the synthesized glasses with Ag addition exhibits improved luminescence, making them potential candidate for white LEDs.
Online tracking and prediction of slip ring degradation using chaos theory based on LSTM neural network
Authors: Zuo Xue , Zhu Rui , Zhou Yuankai 
Published: January 2023

Abstract
The online monitoring of the slip ring is important for ensuring normal operations of wind turbine equipment. A current-carrying friction experiment was conducted to simulate the degradation process of the slip ring. The chaotic parameter enclosing the radius and statistical parameter root mean square (RMS) were used to characterize the multi-sensor signals comprehensively. A new health indicator (HI) was proposed to evaluate the degradation state of slip rings based on long- and short-term memory neural networks. It was fused by the signals of friction vibration, friction torque, voltage and electric current. The HI presents a better prediction effect by the prediction model. At the severe stage of the slip ring, the evaluation criteria mean absolute error, root mean square error and mean percentage error of the HI were 0.0306, 0.0323 and 5.0225% respectively. These values are much better than the RMS of the vibration signal. The results verify that the method can effectively determine the real-time degradation state of the slip ring.
Crystal structure and photoluminescence of ZnSe and ZnSe:Mn nanocrystals obtained by combustion synthesis
Authors: Plakhtii Ye G , Khmelenko O V 
Published: January 2023

Abstract
ZnSe and ZnSe:Mn nanocrystals were obtained by combustion synthesis (self-propagating high-temperature synthesis) using current pulses to initiate a reaction with amplitudes of ∼35 A and ∼40 A. The magnitude of the amplitude of the current pulse affects the size of the nanocrystals, their phase composition, the ratio of the cubic and hexagonal phases, the degree of microstresses and the density of dislocations. The inclusion of Mn dopants into ZnSe has little effect on the nanocrystal morphology and strongly influences the morphology of polycrystals. An EPR spectrum of Mn2+ ions with a hyperfine structure constant A = 6.55 mТ and a g-factor g = 2.0055, which is due to Mn2+ ions in a cubic environment, was found in self-activated and doped ZnSe and ZnSe: Mn nanocrystals. It was found that increasing the amplitude of the current pulse, which initiates the combustion synthesis reaction, increases the intensity of the diffusion processes and more effective isovalent substitution of Zn2+ ions by Mn2+ ions in the crystal lattice of ZnSe nanocrystals. The photoluminescence spectra of ZnSe and ZnSe:Mn nanocrystals were investigated, and individual emission bands were detected in the integral spectra. There were three such individual bands in the photoluminescence spectrum of ZnSe nanocrystals. Their maxima were characterized using the following parameters: λ
max = 592 nm (E = 2.095 eV), λ
max = 543 nm (E = 2.282 eV), and λ
max = 505 nm (E = 2.455 eV). Six individual emission bands were detected in the photoluminescence spectra of ZnSe:Mn nanocrystals with the parameters: λ
max = 675. 5 nm (E = 1.835 eV), λ
max = 642.5 nm (E = 1.929 eV), λ
max = 613 nm (E = 2.022 eV), λ
max = 583.5 nm (E = 2.124 eV), λ
max = 550 nm (E = 2.255 eV), λ
max = 528.5 nm (E = 2.345 eV). This paper discusses the nature of the centers of radiative recombination of individual bands.

Investigation of dust ion acoustic shock and solitary waves in a viscous dusty plasma
Authors: Goswami J , Kausik S S 
Published: January 2023

Abstract
A viscous dusty plasma containing Kappa-(κ − ) distributed electrons, positive warm viscous ions, and constant negatively charged dust grains with viscosity have been considered to study the modes of dust-ion-acoustic waves (DIAWs) theoretically and numerically. The derivations and basic features of shock and solitary waves with different plasma parameters like Mach number, finite temperature coefficient, unperturbed dust streaming velocity, the kinematic viscosity of dust, etc of this DIAWs mode have been performed. Considering the dynamical equation from Korteweg-de Vries(KdV) equation, a phase portrait has been drawn and the position of the saddle point or col. and center have also been discussed. This type of dusty plasma can be found in celestial bodies. The results of this research work can be applied to study the properties of DIAWs in various astrophysical situations where κ-distributive electrons are present and careful modification of the same model can help us to understand the nature of the DIAWs of laboratory plasma as well.
Handling uncertainty in rheological properties of green eggshell nanocomposites by a fuzzy-hybrid modeling approach: a comparative study

Published: January 2023

Abstract
Fuzzy regression is an attractive application due to its ability to solve problems in the absence of accurate mathematical models. In this study, rheological properties of a bio-nanocomposite were predicted using fuzzy regression. The aim of study is to introduce the methodology and application of fuzziness in detail for handling uncertainty in the experimental data. In this context, rheological properties of green eggshell bio-nanocomposites are investigated using different operating parameters. Since the determination of surface tension is prone to experimental errors, a novel fuzzy-hybrid model is proposed in addition to a crisp model. Statistical error analysis is conducted to assess the validity of the multivariate models proposed. While both models provided satisfactory results, it is observed that the fuzzy-hybrid model outperforms the crisp model in both accuracy and generality. This study highlights that the proposed models have an impressive potential to be used for modeling experimental studies in nanotechnological manufacturing applications.
