Low-Energy Electron Scattering from Ethyl Amine and Propyl Amine: A Comparative Study.

In this study, we investigate the low-energy electron (<20 eV) scattering cross sections for the linear ethyl amine and propyl amine using the R-matrix approach. A theoretical study is conducted, covering various cross sections such as elastic, symmetry-wise elastic, differential, momentum transfer, and electronic excitation. We obtained the ionization cross section using the CSP-ic and BEB methodologies.

Deep Learning for 3D Reconstruction, Augmentation, and Registration: A Review Paper.

The research groups in computer vision, graphics, and machine learning have dedicated a substantial amount of attention to the areas of 3D object reconstruction, augmentation, and registration. Deep learning is the predominant method used in artificial intelligence for addressing computer vision challenges. However, deep learning on three-dimensional data presents distinct obstacles and is now in its nascent phase.

Electron impact scattering and electronic excitation in glycolaldehyde: The first ever detected sugar in space.

Detailed theoretical investigations on structural, spectroscopic and electron scattering cross sections of glycolaldehyde, the first ever detected sugar in space are reported in this work. Spectroscopic calculations are performed on the ground and excited states of glycolaldehyde using density functional theory (DFT) and time-dependent density functional theory (TDDFT), respectively. The optimized geometrical parameters and vibrational spectrum are in good agreement with the earlier reported work.

Theoretical Investigation of Dissociative Electron Attachment of Acrylonitrile.

Dissociative electron attachment (DEA) of acrylonitrile (CHCN) is investigated theoretically for two dominant anions CN and CN for the electron impact energy range of 0-20 eV. The present low-energy DEA calculations are performed using the UK molecular R-matrix code using Quantemol-N. We have performed static exchange polarization (SEP) calculations by employing a cc-pVTZ basis set.

A Survey on Deep Learning Based Segmentation, Detection and Classification for 3D Point Clouds.

The computer vision, graphics, and machine learning research groups have given a significant amount of focus to 3D object recognition (segmentation, detection, and classification). Deep learning approaches have lately emerged as the preferred method for 3D segmentation problems as a result of their outstanding performance in 2D computer vision. As a result, many innovative approaches have been proposed and validated on multiple benchmark datasets.

Influence of interstitial UO doping on the valence control of Eu and energy transfer to substitutional Eu and Sm in SrBPO.

Controlling the valence mixing of Eu/Eu and energy transfer between activator ions in solid solution is an important process to improve the efficiency and specificity of phosphors. In this work, the structural and optical properties of stillwellite type SrBPO doped with uranium/europium/samarium, as prepared by conventional solid-state reaction synthesis, were investigated. PXRD studies and Rietveld analysis were carried out to determine the structure, phase purity, and coordination environment of the dopants in the host matrix.

Prediction of sgRNA Off-Target Activity in CRISPR/Cas9 Gene Editing Using Graph Convolution Network.

CRISPR/Cas9 is a powerful genome-editing technology that has been widely applied in targeted gene repair and gene expression regulation. One of the main challenges for the CRISPR/Cas9 system is the occurrence of unexpected cleavage at some sites (off-targets) and predicting them is necessary due to its relevance in gene editing research. Very few deep learning models have been developed so far to predict the off-target propensity of single guide RNA (sgRNA) at specific DNA fragments by using artificial feature extract operations and machine learning techniques; however, this is a convoluted process that is difficult to understand and implement for researchers.

SrBPO: Ce, Dy - A cold white-light emitting phosphor.

A single-component white-light emitting phosphor SrBPO: Ce, Dy with high color purity, good quantum efficiency and high thermal stability was prepared through the conventional high temperature solid state reaction. PXRD studies confirmed its phase purity. The suitability of Strontium borophosphate as a host for phosphor was confirmed through DFT calculations.

Positron emission tomography-computed tomography-associated incidental neoplasms of the thyroid gland.

With the increasing use of F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) scans in oncology, the finding of thyroid incidentalomas, also popularly described as PET-associated incidental neoplasms (PAINs) of the thyroid gland is not unusual. The F-FDG PET-CT scans of all patients who underwent imaging for indications other than thyroid malignancy at our tertiary care center between January 1 and December 31, 2017, were retrospectively reviewed for PAINs of the thyroid. A total of 1737 F-FDG PET-CT scans were done at our center in the year 2017.

Probing the optical properties and luminescence mechanism of a UV-emitting SrBPO :Ce phosphor.

Ce-doped (1 × 10 to 3.0 mol%) SrBPO phosphors were synthesized using a conventional solid-state reaction route at 1273 K in an air atmosphere. Phase and morphology of the samples were studied from powder X-ray diffraction (XRD) patterns and scanning electron microscope (SEM) micrographs, respectively.

Advanced Glycation End Products: Association with the Pathogenesis of Diseases and the Current Therapeutic Advances.

Advanced glycation end products (AGE) such as N-ε-carboxy-ethyl-lysine (CEL), N-ε-carboxy-methyl-lysine (CML), imidazolone, methyl-glyoxal-lysine dimer (MOLD), glyoxal-lysine dimer (GOLD), pyrraline and pentosidine have been imparted in the development and worsening of complications of diabetes. They are also involved in atherosclerosis, normal aging process, arthritis, cancer and progression of age-related neurodegenerative diseases like Alzheimer`s disease. Endogenously, they are formed by nonenzymatic glycation by aldoses/ketoses to form intermediate precursor that were slowly converted into AGE.
