The wave function regards like localized orbital locator, electron localized function, average localized ionization energy and non-covalent interaction are also examined as a means of theoretical evidence of the titled compound. The NBO calculations probe the intermolecular and intramolecular movement of charges, and additionally the molecule's stability. The ADMET properties are also considered for the compound with the assistance of Swiss ADMET online tool.

In the present study, a novel indicator extracted from FRFs of beam structures is developed for crack identification. The damage indicator originated from the well-known mode assurance criterion (MAC) and therefore it is termed spectral assurance criterion (SAC).

This paper presents a simplified model of cracked beam by single-degree-offreedom system. Equivalence between the beam and SDOF models means that they have the same fundamental natural frequency and similar frequency response functions (FRFs).

This work demonstrates a new design of an imaging objective operating in the near-infrared spectral region for vein finder devices. The objective has a simple structure, consisting of 6 elements divided into 2 groups and a long-pass optical filter that allows a near-infrared spectrum to pass through.

Color perception is important for fish to survive and reproduce in nature. Visual pigments in the retinal photoreceptor cells are responsible for receiving light stimuli, but the function of the pigments in vivo has not been directly investigated in many animals due to the lack of color-blind lines and appropriate color-perception tests.

In this paper, we demonstrate a homemade setup and an image processing algorithm to evaluate the image quality of optical systems working in the spectral region of 8-12 µm. The working principle of our approach relies on measuring the line spread function (LSF) and the modulation transfer function.

Unexpected routes to synthesize functionalized benzoxocinones and heteroannulated pyranochromenes were achieved via transformations of the γ -pyrone ring in chromone-3-carboxylic acid throughout its reactions with some acyclic and cyclic carbon nucleophiles. A key part of the reaction mechanisms is discussed. Structures of the new synthesized products were established on the basis of elemental analysis and spectral data (IR, MS, and 1H and 13C NMR).

The photophysical properties of new sulfonamides synthesized recently were investigated in different solvents. Shifts in the absorption and fluorescence spectra of both compounds (S10 and S11) occurred depending on the solvents used. Ground and excited state dipole moments of the molecules were calculated using the spectral shifts of the compounds in different solvents and polarity function of solvents, respectively. They were 1.32 and 1.46 D for S10 and 1.71 and 4.89 D for S11.

Spectral entropy is a basic measure of information available in the material interior about surface loads, or a measure of disorder introduced into elastic medium by the deformation. An exact analytical entropy function is derived for an isotropic plane solid under Gauss-distributed and point loads.

The samples annealed at 150 C and 250 C showed a better optical absorption in the visible and the near infrared spectral regions with dominant characteristic peaks at 691.2 nm and 801.6 nm. Further studies assured that the EPC process yielded good quality and large area MoSe2 films with exotic structural, optical and nanomorphological characteristics that are highly suitable for functional devices.

ZnO:Ni powders are prepared by forced hydrolysis method. The samples were investigated by using XRD, SEM and photoluminescence (PL) spectra. The intensity of near band gap photoluminescence as a function of doping concentration and temperature was studied. The researching results show the doping concentration of Ni strongly affected the luminescence in the UV spectral region and reveal application potential of ZnO:Ni material in optoelectronic and magneto-optical devices of UV range.

This study aimed to propose a mathematical method to investigate and optimize the simultaneous elimination process of multiple organic pollutants using the Fenton process. Hence, the treatment of rhodamine B (RB) and acid red 14 (AR14) dyes in their binary solution was studied. Multivariate curve resolution alternating least square (MCR-ALS), a novel chemometric method, was applied along with correlation constraints to resolute the UV-Vis spectrophotometric data, enabling quantification of investigated dyes despite a high spectral overlapping.

In the current research work, a facile synthesis of a series of novel thiophene-based derivatives of 5-bromothiophene-2- carboxylic acid (1) have been synthesized. All analogs (5a-5e, 10a-10f) were obtained from the coupling reaction of 5-bromothiophene2-carboxylic acid (1) and different arylboronic acids with moderate-to-good yields under controlled and optimal conditions. The structures of the newly synthesized compounds were characterized through spectral analysis and their spasmolytic activity, and most of the compounds exhibited potentially good spasmolytic effect.

Regulation mechanisms between miRNAs and genes are complicated. To accomplish a biological function, a miRNA may regulate multiple target genes, and similarly a target gene may be regulated by multiple miRNAs. Wet-lab knowledge of co-regulating miRNAs is limited.

In this paper, we estimate the scale of time consumption of such calculation in comparison to that of time-independent calculation, and present our solution to the problem by using parallel computing as implementing both MPI and OpenMP to the calculation. We also discuss the possibility to exploit parallel computing with GPU in the near future, and the preliminary results of time-dependent spectral function.
