Authors: V Raghuraman , T Sampath Kumar 
Published: March 2024

Abstract
The laser powder bed fusion LPBF method in additive manufacturing for metals have proven to produce a final product with higher relative density, when compare to other metal additive manufacturing processes like WAAM, DED and it takes less time even for complex designs. Despite the use of many metal-based raw materials in the LPBF method for production of products. Maraging steel (martensitic steel) is used in aeronautical and aircraft applications in view of its advantages including low weight, high strength, long-term corrosion resistance, low cost, availability, and recyclability. A research gap concerns the selection of design, dimension, accuracy, process parameters according to different grades, and unawareness of various maraging steels other than specific maraging steels. In this comprehensive review, the research paper provides information about on LPBF maraging steel grades, their process parameters and defects, microstructure characteristics, heat treatments, and the resulting mechanical characteristics changes. In addition, detailed information about the aging properties, fatigue, residual and future scope of different maraging steel grades in LPBF for various applications are discussed.

Published: March 2024

Abstract
Formaldoxime (CH2NOH) belongs to the possible interstellar molecules. Its isomerization, spectroscopic properties as well as the potential for pumped laser action has long received a lot of attention. Herein, the benchmark database of the spectroscopic constants and anharmonic force fields has been achieved for trans- and cis- formaldoxime. Evaluation is done by using the coupled-cluster theory [CCSD(T)] and density functional theory (B3LYP and B2PLYP), and different basis sets [cc-pVTZ, aug-cc-pVTZ, 6-311+G**, 6-311++G (3df,3pd)] are utilized. The calculated spectroscopic constants commendably reproduce previous experimental results. Besides, a series of vital anharmonic parameters such as vibration-rotation interaction constants, etc, has been provided, which is used for the in-depth study of high-resolution rovibronic spectrum of formaldoxime.
Are there any extragalactic high speed dark matter particles in the Solar neighborhood?
Authors: Santos-Santos Isabel , Bozorgnia Nassim , Fattahi Azadeh , Navarro Julio F. 
Published: March 2024

Abstract
We use the APOSTLE suite of cosmological hydrodynamical simulations of the Local Group to examine the high speed tail of the local dark matter velocity distribution in simulated Milky Way analogues. The velocity distribution in the Solar neighborhood is well approximated by a generalized Maxwellian distribution sharply truncated at a well-defined maximum “escape” speed. The truncated generalized Maxwellian distribution accurately models the local dark matter velocity distribution of all our Milky Way analogues, with no evidence for any separate extragalactic high-speed components. The local maximum speed is well approximated by the terminal velocity expected for particles able to reach the Solar neighborhood in a Hubble time from the farthest confines of the Local Group. This timing constraint means that the local dark matter velocity distribution is unlikely to contain any high-speed particles contributed by the Virgo Supercluster “envelope”, as argued in recent work. Particles in the Solar neighborhood with speeds close to the local maximum speed can reach well outside the virial radius of the Galaxy, and, in that sense, belong to the Local Group envelope posited in earlier work.
The local manifestation of such envelope is thus not a distinct high-speed component, but rather simply the high-speed tail of the truncated Maxwellian distribution.
High-accuracy determination of the beam divergence error in free-fall absolute gravimeters
Authors: Rothleitner Ch , Andreas B 
Published: March 2024

Abstract
We investigate the bias due to the beam divergence of the collimator in a free-fall absolute gravimeter of type FG5X. First, we measure the beam parameters with a Shack-Hartmann sensor. Then, we use the parameters to simulate the relative gravitational acceleration error of an FG5X gravimeter, which employs an unbalanced Mach-Zehnder laser interferometer. This investigation we do with four different commercial collimators, providing different divergence angles. We compare the results to real gravity measurements using the same collimators. The larger the divergence angle, and the bigger the relative length error, the bigger is the bias in the gravity measurements. A good agreement between theory and experiment is found, resulting in a relative bias of

The outcome is also important for the realization of the SI unit kilogram via Kibble balance experiments that, on one side, employ laser interferometers for velocity measurements, and, on the other side, require accurate values of the gravitational acceleration. For example, if this divergence error is not corrected in the Kibble balance, then the mass determination would be biased by

Study on friction and wear behavior of gray cast iron with different carbon content at different temperatures
Authors: Chen Tiefang , Wang Chenggang , Yan Ruifang , Li Feng , Wang Jiandong , Wang Jinguo 
Published: March 2024

Abstract
In this paper, we study the friction and wear properties of gray cast iron with different carbon contents at various ambient temperatures. We also examine the failure forms of gray cast iron friction and wear. The research concludes that under low-temperature wear conditions, the graphite in the gray cast iron structure can enter into the interface between the friction pair, have a lubricating effect on the wear surface, and reduce the friction coefficient and wear loss of the gray cast iron material. As the graphite content in the gray cast iron structure increases, its lubrication and protection effects enhance. Consequently, the primary cause of wear failure in gray cast iron is fatigue peeling induced by plastic deformation. Under high-temperature wear conditions, an oxide layer gradually forms on the wear surface. As the experimental temperature increases, the thickness of the oxide layer on the wear surface also increases. When the oxide layer formed on the wear surface reaches a certain level of thickness, the internal expansion stress of the oxide layer increases considerably, causing the oxide layer to peel off and increase the roughness of the wear surface, friction coefficient, and wear loss. Additionally, an increase in the graphite content in the gray cast iron structure makes the surface more prone to oxidation. This leads to increased friction coefficient and wear loss, with the wear failure of gray cast iron primarily caused by the peeling of the oxidation layer.

Published: March 2024

Abstract
Iron oxide nanoparticles (Fe2O3 NPs) were synthesized utilizing Mentha spicata sourced from Cyprus as a stabilizing agent. The study delved into assessing the antimicrobial, cytotoxic, anti-proliferative, and anti-migratory potential of Fe2O3 NPs through disc diffusion, trypan blue, and 3-[4, 5-dimethylthiazol-2-yl]−2, 5-diphenyltetrazolium bromide (MTT) assay, respectively. Characterization of the synthesized Fe2O3 NPs was conducted using Fourier-transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), UV–vis spectroscopy (UV–vis), scanning electron microscopy (SEM), and energy-dispersive x-ray spectroscopy (EDX). The FTIR, XRD, and SEM-EDX spectra confirmed the successful formation of Fe2O3 NPs. The analysis of UV–vis spectra indicates an absorption peak at 302 nm, thereby confirming both the successful synthesis and remarkable stability of the nanoparticles. The nanoparticles exhibited uniform spherical morphology and contained Fe, O, and N, indicating the synthesis of Fe2O3 NPs. Additionally, the Fe2O3 NPs formed through biosynthesis demonstrated antimicrobial capabilities against Escherichia coli and Bacillus cereus. The significant anti-migratory potential on MDA-MB 231 human breast cancer cells was observed with lower concentrations of the biosynthesized Fe2O3 NPs, and higher concentrations revealed cytotoxic effects on the cells with an IC50 of 95.7 μg/ml. Stable Fe2O3 NPs were synthesized using Mentha spicata aqueous extract, and it revealed antimicrobial activity on E. coli and B. cereus, cytotoxic, anti-proliferative and anti-migratory effect on highly metastatic human breast cancer cell lines.
Introduction: Doing Philosophy between Worlds
Authors: Carpenter Amber D , Harter Pierre-Julien 
Published: March 2024

Abstract
When considered as a list of doctrines, Buddhism and Platonism seem unlikely interlocutors, with diametrically opposed views on reality, knowledge, intelligibility, soul, and ethics. But taking individual philosophers as the systematic, critical inquirers they took themselves to be opens up rich possibilities for constructive philosophical dialogue—particularly given a shared suspicion of the value of ordinary conceptions running through the internal diversity of both traditions, and a shared aspiration to radically transform ourselves for the better. By bringing a team of specialists in each tradition into a multi-year process of collaborative study, we have been able to put the tools of the history of philosophy to work philosophically, creating searching conversations between Buddhist and Platonist that are at once textually grounded and philosophically oriented, and do equal justice to the acuity of each tradition. These curated joint inquiries addressing specific shared concerns take many different forms—collaborative, critical, constructive extensions, the exposure of deep conceptual connections and conflicts. But all forms of this cosmopolitan ancient philosophy work from the fine-grained particulars in classic philosophical texts of distinct philosophical traditions towards creating a more inclusive philosophical community, opening new perspectives on our own philosophical preoccupations, and enriching our understanding of what questions there are to ask and what possibilities there may be for addressing them.
Plato’s Catuṣkoṭi and Nāgārjuna’s Parmenides
Authors: Pinchard Alexis 
Published: March 2024

Abstract
In the dialectical exercise of Plato’s Parmenides, the intrinsically contradictory deductions drawn from the hypotheses about the One imply that the One is neither existent nor nonexistent, neither endowed with an essence nor deprived thereof. Does this symmetrical negation constitute a self-refutation of Plato’s metaphysics, or is it evidence that “the One” refers to the same thing as the sovereign “Good” of the Republic, which is also supposed to stand beyond essence? Rewriting the Parmenides with Nāgārjuna’s concepts could help to answer this question. It looks as if Plato used the various predicative combinations of the Mādhyamika tetralemma, especially the symmetrical negation, in order to remove our native oblivion concerning the axiological status of the One, just like Nāgārjuna used it to remove our hypostatizing habits concerning the phenomena of everyday life. Conversely, the soteriological purpose of Mādhyamika dialectic becomes clearer when contrasted with the Platonic project to reach an unconditioned principle.
How I diagnose and manage VEXAS syndrome
Authors: Hagiya Ashley , Siddiqi Imran N , Wang Endi , Lu Chuanyi M 
Published: March 2024

Abstract

Objectives
To discuss VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome, including the clinical and pathologic features, diagnostic challenges, and treatment options.

Methods
A case-based approach and pertinent literature review were used to highlight the features of VEXAS syndrome, describe how to make the diagnosis, and discuss available therapies.

Results
VEXAS syndrome is an adult-onset, progressive systemic inflammatory disorder with overlapping rheumatologic and hematologic manifestations, including an increased risk of myelodysplastic neoplasms and plasma cell neoplasms. The disorder is associated with a somatic mutation of the X-linked UBA1 gene involved in ubiquitylation, typically involving p.Met41; however, rare variations have been identified outside this region. Patients often present with complex histories and see physicians from multiple specialties before receiving the diagnosis, which is often delayed. Symptoms are related to inflammation as well as cytopenias, particularly macrocytic anemia. Characteristic cytoplasmic vacuoles are present in myeloid (granulocytic, monocytic) and erythroid precursors in the vast majority of cases.

Conclusions
Either clinicians or pathologists may suspect a diagnosis of VEXAS syndrome depending on the clinical presentation and bone marrow findings. More studies are needed to determine the best therapeutic options, which are currently limited.
Does Developing Interpregnancy Hypertension Affect the Recurrence Risk of Preeclampsia? A Population-Based Cohort Study
Authors: Ragnarsdóttir Inger Björk , Akhter Tansim , Junus Katja , Lindström Linda , Lager Susanne , Wikström Anna-Karin 
Published: March 2024

Abstract

BACKGROUND
Preeclampsia in a first pregnancy is a strong risk factor for preeclampsia in a second pregnancy. Whether chronic hypertension developed after a first pregnancy (interpregnancy hypertension) affects the recurrence risk of preeclampsia is unknown.

METHODS
This is a population-based cohort study of 391,645 women with their first and second singleton births between 2006 and 2017. Exposure groups were women with preeclampsia in their first pregnancy, interpregnancy hypertension, or both risk factors. Women with neither risk factor were used as a reference group. We calculated the adjusted relative risk (aRR) with 95% confidence intervals (CIs) for overall preeclampsia in the second pregnancy as well as preterm (&lt;37 gestational weeks) and term (≥37 gestational weeks) subgroups of the disease.

RESULTS
Women with preeclampsia in their first pregnancy who did or did not develop interpregnancy hypertension had rates of preeclampsia in their second pregnancy of 21.5% and 13.6%, respectively. In the same population, the corresponding rates of preterm preeclampsia were 5.5% and 2.6%, respectively. After adjusting for maternal factors, women with preeclampsia in their first pregnancy who developed interpregnancy hypertension and those who did not have almost the same risk of overall preeclampsia in their second pregnancy (aRRs with 95% CIs: 14.51; 11.77–17.89 and 12.83; 12.09–13.62, respectively). However, preeclampsia in the first pregnancy and interpregnancy hypertension had a synergistic interaction on the outcome of preterm preeclampsia (aRR with 95% CI 26.66; 17.44–40.80).

CONCLUSIONS
Women with previous preeclampsia who developed interpregnancy hypertension had a very high rate of preterm preeclampsia in a second pregnancy, and the two risk factors had a synergistic interaction.
Pre-gestational counselling for women living with CKD: starting from the bright side
Authors: Da Silva Iara , Orozco-Guillén Alejandra , Longhitano Elisa , Ballarin José Aurelio , Piccoli Giorgina Barbara 
Published: March 2024

ABSTRACT
Pregnancy in women living with chronic kidney disease (CKD) was often discouraged due to the risk of adverse maternal–fetal outcomes and the progression of kidney disease. This negative attitude has changed in recent years, with greater emphasis on patient empowerment than on the imperative ‘non nocere’. Although risks persist, pregnancy outcomes even in advanced CKD have significantly improved, for both the mother and the newborn. Adequate counselling can help to minimize risks and support a more conscious and informed approach to those risks that are unavoidable. Pre-conception counselling enables a woman to plan the most appropriate moment for her to try to become pregnant. Counselling is context sensitive and needs to be discussed also within an ethical framework. Classically, counselling is more focused on risks than on the probability of a successful outcome. ‘Positive counselling’, highlighting also the chances of a favourable outcome, can help to strengthen the patient–physician relationship, which is a powerful means of optimizing adherence and compliance. Since, due to the heterogeneity of CKD, giving exact figures in single cases is difficult and may even be impossible, a scenario-based approach may help understanding and facing favourable outcomes and adverse events. Pregnancy outcomes modulate the future life of the mother and of her baby; hence the concept of ‘post partum’ counselling is also introduced, discussing how pregnancy results may modulate the long-term prognosis of the mother and the child and the future pregnancies.
Non-HDL cholesterol and residual cardiovascular risk in statin-treated patients with and without diabetes: the Western Denmark Heart Registry
Authors: Hansen Malene Kærslund , Mortensen Martin Bødtker , Olesen Kevin Kris Warnakula , Thrane Pernille Gro , Thomsen Reimar Wernich , Maeng Michael 
Published: March 2024

Abstract

Aims
Assessment of residual cardiovascular risk in statin-treated patients with atherosclerotic cardiovascular disease (ASCVD) is pivotal for optimizing secondary preventive therapies. This study investigates if non–high-density lipoprotein cholesterol (non-HDL-C) is associated with residual ASCVD risk in statin-treated ischaemic heart disease (IHD) patients with and without diabetes.

Methods and results
Using the Western Denmark Heart Registry, we identified statin-treated patients with IHD examined by coronary angiography (CAG) from 2011 to 2020. Non-HDL-C was assessed within 1 year after CAG. Outcomes were ASCVD (myocardial infarction, ischaemic stroke, and cardiovascular death) and all-cause death. Cox regression analyses obtained hazard ratios (HRs) adjusted for age, sex, smoking, and hypertension. A total of 42 057 patients were included: 8196 patients with diabetes and 33 861 without diabetes. During the median 4.6 years of follow-up, event rates per 1000 person-years of ASCVD were 28.8 (27.1–30.5) and 17.2 (16.5–17.8) among patients with and without diabetes. In patients with diabetes, the adjusted HRs of ASCVD as compared with non-HDL-C &lt; 25th percentile were 1.0 (0.9–1.2), 1.3 (1.1–1.6), and 1.6 (1.2–2.1) for patients in the 25th–74th, 75th–94th, and ≥95th percentiles. In patients without diabetes, the corresponding adjusted HRs were 1.1 (0.9–1.1), 1.2 (1.1–1.4), and 1.7 (1.4–2.0). Results were consistent across sex, age, clinical presentation, and low-density lipoprotein cholesterol strata.

Conclusion
In statin-treated IHD patients with and without diabetes, non-HDL-C, especially above the 75th percentile, is associated with residual cardiovascular risk. These results have implications for secondary prevention, targeting patients who may benefit most from intensified preventive therapy.
Transcribing the enigma: the B chromosome as a territory of uncharted RNAs
Authors: Oliveira Jordana Inácio Nascimento , Cabral-de-Mello Diogo C , Valente Guilherme T , Martins Cesar 
Published: March 2024

Abstract
B chromosomes are supernumerary elements found in several groups of eukaryotes, including fungi, plants, and animals. Typically, these chromosomes either originate from their hosts through errors in meiosis or interspecifically through horizontal transfer. While many B chromosomes are primarily heterochromatic and possess a low number of coding genes, these additional elements are still capable of transcribing sequences and exerting influence on the expression of host genes. How B chromosomes escape elimination and which impacts can be promoted in the cell always intrigued the cytogeneticists. In pursuit of understanding the behavior and functional impacts of these extra elements, cytogenetic studies meet the advances of molecular biology, incorporating various techniques into investigating B chromosomes from a functional perspective. In this review, we present a timeline of studies investigating B chromosomes and RNAs, highlighting the advances and key findings throughout their history. Additionally, we identified which RNA classes are reported in the B chromosomes and emphasized the necessity for further investigation into new perspectives on the B chromosome functions. In this context, we present a phylogenetic tree that illustrates which branches either report B chromosome presence or have functional RNA studies related to B chromosomes. We propose investigating other unexplored RNA classes and conducting functional analysis in conjunction with cytogenetic studies to enhance our understanding of the B chromosome from an RNA perspective.

Published: March 2024

Abstract

Background
This study investigated the association between previous incarceration and various geriatric and chronic health conditions among adults 50 and older in the United States.

Methods
Data came from the National Longitudinal Study of Adolescent to Adult Health—Parent Study (AHPS) collected in 2015–2017, including 2 007 individuals who participated in the parent study (Parent Sample) and 976 individuals who participated in the spouse/partner study (Spouse/Partner Sample). Multiple logistic regression was used to investigate the relationship between previous incarceration and geriatric syndromes (dementia, difficulty walking, difficulty seeing, difficulty with activities of daily living) and chronic health conditions (self-reported poor/fair health, diagnosis of cancer, hypertension, diabetes, heart disease, stroke, chronic lung disease, depression, and alcohol use [4 or more drinks per week]).

Results
In adjusted analyses, respondents with previous incarceration in the AHPS had significantly higher odds of reporting difficulty walking, activities of daily living difficulty, cancer diagnosis, depression diagnosis, and chronic lung disease (adjusted odds ratios [aORs] = 2.21–2.95). Respondents in the AHPS spouse/partner study reported higher odds of difficulty seeing, cancer, depression, chronic lung disease, and heavy alcohol use (aORs = 1.02–2.15).

Conclusions
Previous incarceration may have an adverse impact on healthy aging. Findings highlight the importance of addressing the enduring health impacts of incarceration, particularly as individual transition into older adulthood.
