Impact of lime on compaction characteristics of Jamshoro shale
The most complex problem for any civil engineering work is when the structure which is laying on the soil is weak. Jamshoro shale is an example of such problematic soil, which gets expanded as soon as it is exposed to moisture and shrinks back once it dries. Such phenomenon is very critical for the structures and road networks built on shale forming settlements and cracks. Such kinds of soil must be stabilized by chemical or mechanical techniques to make them strong enough to carry the loads and resist settlements and cracking. The stabilization of the ground by utilizing or adding any chemical agent is a sustainable approach; it strengthens the soil properties without replacing or wasting the soil present. In this research, the treatment of lime with shale is been performed to observe the modification of the geotechnical characteristics of the soil. The different proportions of Hydrated Lime 0%, 7%, 8%, and 9% were mixed by the dry weight of soil to investigate the effect of lime on the compaction and plasticity characteristics of the shale. Various tests such as the modified proctor test, liquid limit test, and plastic limit test performed in the laboratory. From the results, it was observed that the properties of Jamshoro shale such as plasticity index, optimum moisture content, and maximum dry density were improved. The plasticity index of shale dropped to 2% from 24%. That suggests lime can be used as an economical and eco-friendly stabilizing agent

Systematic study of optoelectronic and thermoelectric properties of AHfO
The physical properties of AHfO3 (A = Ca, Ba) are revealed using the density functional theory (DFT) based FP-LAPW+lo approach. The existing work investigates the pressure dependence of mechanical, electronic characteristics for specifying the optical and thermoelectric device applications of alkaline rare-earth hafnate perovskites. The PBEsol-GGA functional has been applied for the dealing of the exchange-correlation energy. The lattice constants of the stable cubic phases are extracted by structural optimization, which is similar to the existing experimental and theoretical literature. The bulk moduli (B) and cubic elastic constants are computed for evaluating the mechanical strength against external pressure up to 15 GPa. The electronic properties reveal that Hf-3d states primarily construct conduction band minima, while O–2p states construct valence band maxima at 0 GPa, exhibiting an indirect bandgap (Γ–M), which has been transformed to direct bandgap (Γ–Γ) at 15 GPa. Investigations of the optical properties illustrate that change in pressure can tune the optical parameters of these materials within ultraviolet (UV) energies suggesting commercial optoelectronic utilities. Our analysis shows that BAHfO3 exhibits better thermoelectric properties than CAHfO3 at room temperature whereas, thermoelectric performance both the compounds become comparable at a higher temperature
Optoelectronic pressure dependent study of alkaline earth based zirconates AZrO
The physical properties of alkaline-earth zirconates AZrO3 (A = Ca, Ba, Sr) are revealed using density functional theory (DFT) based FP-LAPW+lo approach. The present study investigates the structural, optoelectronic, and thermoelectric features, which are elucidated using GGA-PBEsol functional. The changing A cations from Ba to Sr to Ca result in increasing lattice constant comparable with experimental data and reducing bulk modulus. The CaZrO3 exhibits comparatively higher stiffness or hardness than that of the SrZrO3 and BaZrO3. The applied pressure improves mechanical stability by increasing ductility. Moreover, electronic structures are computed under varying pressures 0–30 GPa. All three compounds show indirect bandgap (Γ–M) up to 20 GPa, and the transition to direct bandgap (Γ–Γ) is illustrated at 30 GPa. Consequently, the significance of optoelectronic applications is revealed. The pressure-dependent various optical parameters are also explored and validation of Penn’s model, transparency, and maximum reflectivity at specific energy ranges expose their possible commercial candidature

Triggering receptor expressed on myeloid cells-1 (TREM-1) inhibition in atherosclerosis
Triggering receptor expressed on myeloid cells-1 (TREM-1) is a transmembrane protein expressed on endothelial cells, white blood cells, smooth muscle cells and platelets. TREM-1 plays an important role in innate immunity. TREM-1 activation pathways are implicated both in sepsis and in non-infectious inflammatory conditions, including atherosclerosis. TREM-1 enhances the subendothelial lipid accumulation and expression of pro-inflammatory cytokines and matrix-degrading enzymes, thereby promoting inflammation and plaque destabilization. TREM-1 inhibitors attenuate the inflammatory process in the atherosclerotic plaque, leading to plaque stabilization. This review focuses on the role of TREM-1 in the pathophysiology of atherosclerosis and the effects of TREM-1 inhibition in the natural history of the disease

Artificial Intelligence, Computational Simulations, and Extended Reality in Cardiovascular Interventions
Artificial intelligence, computational simulations, and extended reality, among other 21st century computational technologies, are changing the health care system. To collectively highlight the most recent advances and benefits of artificial intelligence, computational simulations, and extended reality in cardiovascular therapies, we coined the abbreviation AISER. The review particularly focuses on the following applications of AISER: 1) preprocedural planning and clinical decision making; 2) virtual clinical trials, and cardiovascular device research, development, and regulatory approval; and 3) education and training of interventional health care professionals and medical technology innovators. We also discuss the obstacles and constraints associated with the application of AISER technologies, as well as the proposed solutions. Interventional health care professionals, computer scientists, biomedical engineers, experts in bioinformatics and visualization, the device industry, ethics committees, and regulatory agencies are expected to streamline the use of AISER technologies in cardiovascular interventions and medicine in general
