AI-based Power Screening Solution for SARS-CoV2 Infection: A Sociodemographic Survey and COVID-19 Cough Detector.

Globally, the confirmed coronavirus (SARS-CoV2) cases are being increasing day by day. Coronavirus (COVID-19) causes an acute infection in the respiratory tract that started spreading in late 2019. Huge datasets of SARS-CoV2 patients can be incorporated and analyzed by machine learning strategies for understanding the pattern of pathological spread and helps to analyze the accuracy and speed of novel therapeutic methodologies, also detect the susceptible people depends on their physiological and genetic aspects. To identify the possible cases faster and rapidly, we propose the Artificial Intelligence (AI) power screening solution for SARS- CoV2 infection that can be deployable through the mobile application. It collects the details of the travel history, symptoms, common signs, gender, age and diagnosis of the cough sound. To examine the sharpness of pathomorphological variations in respiratory tracts induced by SARS-CoV2, that compared to other respiratory illnesses to address this issue. To overcome the shortage of SARS-CoV2 datasets, we apply the transfer learning technique. Multipronged mediator for risk-averse Artificial Intelligence Architecture is induced for minimizing the false diagnosis of risk-stemming from the problem of complex dimensionality. This proposed application provides early detection and prior screening for SARS-CoV2 cases. Huge data points can be processed through AI framework that can examine the users and classify them into "Probably COVID", "Probably not COVID" and "Result indeterminate".

Crystal structure of 4-sulfamoylanilinium di-hydrogen phosphate.

In the crystal structure of the title mol-ecular salt, C6H9N2O2S(+)·H2PO4 (-), the sulfomylalinium cations and the di-hydrogen phosphate anions form independent [100] chains through Ns-H⋯O (s = sulfamo-yl) and O-H⋯O hydrogen bonds, respectively. The chains are cross-linked by Na-H⋯O (a = amine) hydrogen bonds, generating (010) sheets. Two C-H⋯O hydrogen bonds involving diametrically opposite C atoms in the benzene ring of the cation as donors form chains parallel to [202] in which P=O and P-OH groups are acceptors. Together, these inter-actions lead to a three-dimensional network.

Bis(4-sulfamoylanilinium) sulfate.

In the title salt, 2C6H9N2O2S(+)·SO4 (2-), the sulfate S atom is situated on a crystallographic twofold axis (the symmetry of the anion is 2). The anion exerts intense libration, which is manifested by shortening of the observed sulfate S-O bonds, as well as by features in the electron-density map. The crystal structure is stabilized through a three-dimensional hydrogen-bonding network formed by strong N-H⋯O hydrogen bonds.

4-Sulfamoylanilinium nitrate.

In the crystal structure of the title compound, C(6)H(9)N(2)O(2)S(+)·NO(3) (-), the cations and anions are connected by N-H⋯O hydrogen bonds into a three-dimensional network.

5''-(4-Chloro-benzyl-idene)-1',1''-dimethyl-3'-phenyl-acenaphthene-1-spiro-2'-pyrrolidine-3'-spiro-3''-pyridine-2,4''-dione.

In the title compound, C(34)H(28)Cl(2)N(2)O(2), the five-membered pyrrolidine ring adopts an envelope conformation and the six-membered piperidinone ring is in a distorted half-chair conformation. The mol-ecular structure shows three intra-molecular C-H⋯O inter-actions and the crystal packing is stabilized through inter-molecular C-H⋯O and C-H⋯π inter-actions.

Infrared and Raman spectroscopic studies of l-valine l-valinium perchlorate monohydrate.

FT-IR and FT-Raman spectra were recorded and analyzed for l-valine l-valinium perchlorate monohydrate crystals. The wave number assignments have been made for the functional groups, viz. COOH, COO(-), --[NH(3)](+), C--(CH(3))(2), C--C--N and C--H. One of the two amino acid residues remains in the zwitterionic form while the other residue exists in the cationic form. The symmetry of the ClO(4)(-) anion has been found to be lowered corresponding to ClO(2) group. The hydrogen bonds that prevail between amino acid residues, perchlorate anion and water molecule influence the wave numbers of several stretching and deformation modes to deviate from the expected values.

Vibrational spectral studies of L-methionine L-methioninium perchlorate monohydrate.

The infrared and laser Raman spectra of L-methionine L-methioninium perchlorate monohydrate were recorded at room temperature and the vibrational assignments of the observed wave numbers were made. The presence of both the carbonyl and the ionized carboxylic groups has been identified in the title complex. The L-methionine and L-methioninium the cation have different conformations. This together with the different environment has seen by the two -CH(2)- groups in each skeleton cause several of the group wave numbers to occur as doublets or as broad bands. The perchlorate anion was found to be in the T(d) symmetry in the methionine environment. The coordination to other ligands in the crystal through hydrogen bonding does not affect this symmetry. The extensive intermolecular hydrogen bonding in the crystal was identified by the shifting of bands due to the stretching and bending modes of the various functional groups. Fermi resonance has also been observed.
