“Regardless of What Life Presents You”
Authors: Fowler Carol , Ziobro Melissa 
Published: June 2024

We posit that many African American women in the modern military do not want to be “gunslingers.” They almost always see their military service not as an adventure, but as a sensible path to self-betterment and upward mobility in a society that often limits their options. They enlist seeking personal advancement, economic empowerment, college tuition, and travel. They enlist because they want to expand their horizons and become more informed global citizens. They often rise through the ranks and become leaders and mentors, in the military and when they return to civilian life. They are black women public intellectuals. This chapter, which is not limited to but focuses on the post-Vietnam era to address a dearth of existing sources, is based on the authors’ analysis of more than 200 veterans’ oral history interviews, in addition to the academic historiography.

Symmetry-breaking-induced off-resonance second-harmonic generation enhancement in asymmetric plasmonic nanoparticle dimers
Authors: Wang Yaorong , Peng Zhiwei , De Wilde Yannick , Lei Dangyuan 
Published: June 2024

Abstract
The linear and nonlinear optical properties of metallic nanoparticles have attracted considerable experimental and theoretical research interest. To date, most researchers have focused primarily on exploiting their plasmon excitation enhanced near-field and far-field responses and related applications in sensing, imaging, energy harvesting, conversion, and storage. Among numerous plasmonic structures, nanoparticle dimers, being a structurally simple and easy-to-prepare system, hold significant importance in the field of nanoplasmonics. In highly symmetric plasmonic nanostructures, although the odd-order optical nonlinearity of the near-surface region will be improved because of the enhanced near-fields, even-order nonlinear processes such as second-harmonic generation (SHG) will still be quenched and thus optically forbidden. Under this premise, it is imperative to introduce structural symmetry breaking to realize plasmon-enhanced even-order optical nonlinearity. Here, we fabricate a series of nanoparticle dimers each composed of two gold nanospheres with different diameters and subsequently investigate their structural asymmetry dependent linear and nonlinear optical properties. We find that the SHG intensities of gold nanosphere dimers are significantly enhanced by structural asymmetry under off-resonance excitation while the plasmonic near-field enhancement mainly affects SHG under on-resonance excitation. Our results reveal that symmetry breaking will play an indispensable role when designing novel coupled plasmonic nanostructures with enhanced nonlinear optical properties.
Mobile news access, mobile news repertoires, and users’ tendency to talk about the news – an experience sampling study on mobile news consumption
Authors: Karnowski Veronika , Knop-Huelss Katharina , Olbermann Zoe 
Published: June 2024

AbstractPurposeOver the past three decades, our media ecologies have substantially transformed, changing how people get in touch with the news. These changes have also led to higher variability in news access across users’ daily lives. Using the microcosm of mobile news consumption as a proxy for the changes in our general news use, we explore types of mobile news access and mobile news repertoires and their relations to users’ tendency to talk about the news. Our exploratory study aims to describe intra- and inter-personal variations in mobile news use. By taking this fine-grained perspective on mobile news use, we provide a more comprehensive assessment than cross-sectional studies, which is valuable to researchers and practitioners in mobile news.MethodologyWe conducted a 14-day experience sampling study among 72 young adult Germans. We received 2,211 filled-in in-situ questionnaires based on three daily alerts, reporting on 560 mobile news situations. We used multi-level latent class analysis to simultaneously assess patterns of mobile news access and mobile news repertoires.FindingsWe uncover five distinct types of mobile news access embedded in four mobile news repertoires. These findings highlight the considerable intra-individual heterogeneity in mobile news use. However, these heterogeneities only scarcely manifest in users’ tendency to talk about the news.Practical and social valueOur study highlights the importance of acknowledging intra-individual variation when studying news use and its implications. Most importantly, we see that no mobile news repertoire among our sample relies solely on social media-based mobile news access. Researchers and practitioners must acknowledge these heterogeneities when discussing the benefits and perils of social media-based news access.
Establishment of a prognostic signature of disulfidptosis-related lncRNAs for predicting survival and immune landscape in clear cell renal cell carcinoma
Authors: Liu Jinhui , Zhang Zhou , Xiao Lei , Guo Yuhang , Luo Sheng , Zhou Benzheng 
Published: June 2024

Abstract

Objectives
A novel cell death pathway, disulfidptosis, marked by intracellular disulfide build-up, is a recently identified form of cell death. This study developed a dependable model using disulfidptosis-associated lncRNAs to predict outcomes and immune interactions in clear cell renal cell carcinoma (ccRCC) patients.

Methods
Data from ccRCC patients, including genomic and clinicopathological details, were sourced from The Cancer Genome Atlas database. We employed the least absolute shrinkage and selection operator (LASSO) along with regression analyses to construct a prognostic model consisting of 12 disulfidptosis-related lncRNAs (DRLs). The model’s validity was tested using the RECA-EU and GSE29609 datasets.

Results
The prognostic model, incorporating 12 DRLs – LINC01671, DOCK9-DT, AL078581.2, SPINT1-AS1, ZNF503-AS1, AL391883.1, AC002070.1, AP001372.2, AC068338.3, AC026401.3, AL355835.1, and AL162377.1 – distinguished high-risk ccRCC patients with diminished survival rates in both the training and validation cohorts. Further analyses through Cox regression confirmed this risk model’s independent prognostic capability regarding overall survival (OS). Functional enrichment analysis indicated significant involvement of differentially expressed genes in immune response mediator production. A prognostic nomogram, integrating DRLs with clinical features, showed strong predictive accuracy as confirmed by receiver operating characteristic curves. Additionally, assessments of immune functionality and tumor mutation burden varied across risk categories in the tumor microenvironment, highlighting potential targets for anticancer drugs.

Conclusions
The findings suggest the DRLs signature is a potent prognostic indicator and may serve to forecast responses to immunotherapy in ccRCC patients.

Abstract
The purpose of this work is to fabricate the advanced organic antibacterial coating containing the strong photocatalytic nanomaterials. For this purpose, firstly the TiO2–Ag hybrid nanoparticles are synthesized by chemical reduction method. Then, the antibacterial coating based on acrylic polyol, polyisocyanate, and these TiO2–Ag hybrid nanoparticles has been prepared. Mechanical properties show that the optimal content of TiO2–Ag hybrid nanoparticles in the coating matrix is 2 wt%, with its abrasion resistance of 166.2 L/mil; impact strength of 195 kg cm; adhesion of size #1 and relative hardness of 0.78. In addition, FE-SEM analysis shows that the nanocomposite coating has a tight structure with homogeneous dispersion of TiO2–Ag nanoparticles in the polymer matrix. The paint film has good antibacterial activity and has great application prospects. Data from the antibacterial test indicates that in the presence of an acrylic polyurethane coating containing 2 wt% TiO2–Ag, the number of viable Escherichia coli decreased from 3.4 × 105 CFU/ml to 1.5 × 102 CFU/ml after 24 h of culture.
Aftershocks of the 2 April 2024 Mw 7.4 Hualin, Taiwan Earthqauke
Authors: Rajesh Rekapalli , Gupta Harsh K. 
Published: June 2024

ABSTRACT
A devastating Mw 7.4 earthquake occurred in Taiwan on the 2 April 2024 at 23:58:11 UTC claiming 14 human lives, injuring over 1000 and causing wide spread structural damage. Moderate aftershocks of major earthquakes tend to cause further damage to already weakened built structures. An assessment of the duration of occurrence of such aftershocks is helpful in post earthquake recovery phase. This earthquake is the most significant earthquake to have occurred after 25 years of the 21 September 1999 Mw 7.7 Chi-Chi earthquake in Taiwan. Our study indicates that there was a paucity of Mw ≥ 5 aftershocks for the Chi-Chi earthquake as only 45 such aftershocks occurred in 40 days. However, an increase in the number of Mw 4.5 earthquakes was observed compared to the background seismicity. Using Omori’s Law, we estimated the duration of Mw ≥ 4.5 aftershocks using the data of first 14 days to be 110 days, that matches quite well with the the Chi-Chi earthquake sequence. The 2 April 2024 Hualin earthquake is quite similar to the 1999 Ch-Chi earthquake. There is a paucity of Mw ≥ 5 for the Hualin earthquake. No such after shock has been recorded after 7 April 2024. However, Mw ≥ 4.5 aftershoks are continuing to occur. Our study, using the data of 14 days after the Hualin earthquake, indicates that Mw ≥ 4.5 aftershocks for the Hualin earthquake shall continue for ∼ 80 days.

ABSTRACT
Dehradun lies in the intermontane Dun Valley in the Garhwal Sub Himalaya, which lies with the Main Boundary Thrust (MBT)- Himalayan Frontal Thrust (HFT) tectonic wedge with other intrawedge faults. These faults may rupture during a great earthquake and cause damage to the existing civil structures in the fault zone. Therefore, it is essential to characterise the active faults in and around Dehradun. We carried out 2D Shear wave velocity profiles across the Markanda Thrust, Rajban Fault, Bata Fault, Santaurgarh Thrust, Bhauwala Thrust, and Majhaun Fault at 18 sites using the Multichannel Analysis of Surface Wave (MASW) technique. The obtained shear wave velocity is further utilised to calculate geotechnical parameters like the average shear wave velocity (Vs30), soil stiffness, amplification factor, and predominant frequency. The weak, weathered or shear zones and dislocations are mapped in terms of a low shear wave velocity layer overlain by a high shear wave velocity layer at deeper depths near identified fault or thrust locations. The active fault/thrust zones in the Dun Valley have a shear wave velocity of 130 m/s to &lt;1500m/s and consist of stiff soil to dense soils of class D to C as per the National Earthquake Hazard Reduction Programme (NEHRP) classification. This study contributes to a better understanding of the seismic characteristics of Dehradun and its surroundings, which is useful for earthquake mitigation studies.
Linear Model for Pore Pressure Predication in Gas Hydrate-bearing Sand Formation of Krishna-Godavari Basin (India) – A Case Study
Authors: Yadav Pradeep Kumar , Shankar Uma 
Published: June 2024

ABSTRACT
Pore pressure is a crucial geomechanical parameter, to decide the mud density while well drilling. The mud weight should be between formation pressure (pore pressure) and the fracture gradient of the reservoir rock, otherwise various kind of unwanted incidents like, kicks, blowout, breakout, well collapse, mud loss and lost circulation can happen; which can increase the cost of drilling and in worst case it may lead to a dangerous accident and consequently loss of life and assets at drilling site. In this study we are trying to find pore pressure within water bearing shale formations and gas hydrate (solid) bearing sand formation of four wells of Area B in the Krishna-Godavari Basin, namely, NGHP-02-17A, 19A, 22A, and 23A. Bower’s sonic, Eaton’s resistivity and Eaton’s sonic empirical equations have been used to estimate effective stress in the water-bearing shale formation. In gas hydrate-bearing sand formations these empirical equations cannot be useful for effective stress or pore pressure estimation and hence a linear model based on pressure-core data, relating effective stress and depth in meter below seafloor (mbsf) is generated .This model is applicable for the effective stress estimation in gas hydrate bearing sand formations of the Krishna-Godavari basin. The effective stress estimated from linear model and from core data are found in good agreement in all the wells. At site NGHP-02-23, in-situ pore-pressure was measured between depth of 270.38 to 271.38 mbsf with the help of modular dynamic formation tester (MDT) tool. The in-situ pore pressure (28.2 MPa) and estimated pore pressure (27.8 MPa) from the linear model are found in good agreement. Further, fracture pressures from Matthew-Kelly and Eaton’s method were estimated. The mud weight base on the reported mud density 1.3g/cc are found to higher than the pore pressures and lower than the fracture pressures and hence fulfil the criteria for safe drilling.
DRASTIC-FS Model for Assessment of Groundwater Vulnerability in Alluvial Region between Mahi and Narmada Rivers, India
Authors: Modi Mukesh A. , Shrimali N.J. 
Published: June 2024

ABSTRACT
Vulnerability of groundwater to contamination in alluvial region between Mahi and Narmada rivers of Gujarat has been assessed in present study. There have been numerous studies that have analyzed DRASTIC models with weights suggested by the Delphi committee. These models have some limitations that have been overcome by optimizing the weights using artificial neural networks (ANNs). The “DRASTIC-FS” model has an additional layer that takes into account the impact of the physico-chemical properties of groundwater. The dominating factor scores (FS) at each well location were derived from the statistical analysis of the quality dataset. Factor score’s rating and the weight have been assigned considering to its intervention and influence to vulnerability. The DRASTIC and DRASTIC-FS models were carried out in GIS environment to obtain vulnerability maps for 2018 pre and post monsoon seasons. The weights of variable parameters (i.e., D, R, I, C, and FS) have also been optimized using ANN (Artificial Neural Network) and the results were compared with the effective weights derived from SPSA method of sensitivity analysis. Using ANN optimized weights and groundwater nitrate concentrations, the vulnerability maps were validated. Vulnerability maps of DRASTIC-FS with ANN weights correlated well for the year 2018, 2019 and 2020 (Pearson’s ‘r’= 0.56, 0.65 and 0.50 respectively) with groundwater Nitrate concentrations proving its higher efficiency over the DRASTIC method (Pearson’s ‘r’= 0.36, 0.48 and 0.32).

Authors: Deshmukh Aniket , Paritekar Anita 
Published: June 2024

Background: ARDS is a progressive inflammatory lung injury in patients with hypoxemic respiratory failure. Aspiration pneumonia and pneumonia are the most common cause of ARDS in direct lung injury whereas sepsis is the most common cause of ARDS in Indirect lung injury.
Methods: This was observational study conducted in Intensive care unit, Department of Medicine, CPR Hospital, Kolhapur, Maharashtra for 6 months from 1 June to 30 November 2023 in 41 patients.
Results: Most common cause of ARDS secondary to pneumonia, in this study population is bacterial pneumonia, followed by viral and parasitic infections. Average day of hospital stay for bacterial pneumonia is 13 days and 11 and 10 days for viral and parasitic infections respectively. For bacterial pneumonia mortality was 36%, for viral pneumonia was 37% and parasitic pneumonia was 33.33%. Out of 41 patients,16 patients were in mild ARDS with the SOFA score range of 2 to 5 and 12 patients were in moderate ARDS with SOFA score range of 6 to 9 and 12 patients were in severe ARDS with SOFA score range of 12 to 14.
Conclusions: With our study we would like to conclude that sofa score is a good predictor of mortality in c/o ARDS patients in ICU setting. Patients who had sofa score of equal or more than 9 and who were in the category of moderate to severe ARDS, had poorer outcomes and high mortality rate.
