INTRODUCTION: Liposuction and mesotherapy are popular treatments for fat reduction of lower face, but because these treatments are invasive, a novel non-invasive treatment with similar or better efficacy has been sought. There are various devices such as CoolSculpt, laser, RF, and HIFU that are used as non-invasive treatments for fat reduction and body contouring, but these applications have not been applied to facial fat reduction. In this study, we selected Monopolar 1-MHz RF for body contouring to be applied for fat reduction and tightening of the lower face...

Motivation: The accuracy of predicting protein local and global structural properties such as secondary structure and solvent accessible surface area has been stagnant for many years because of the challenge of accounting for non-local interactions between amino acid residues that are close in three-dimensional structural space but far from each other in their sequence positions. All existing machine-learning techniques relied on a sliding window of 10-20 amino acid residues to capture some "short to intermediate" non-local interactions...

INTRODUCTION: Anatomical change of tumor during radiotherapy contributes to target missing. However, in case of tumor shrinkage adaptation of volume could results in an increased incidence of recurrences in the area of target reduction. This study aims to investigate the incidence of failure of adaptive approach and in particular the risk of local recurrence in the area excluded after replanning. METHODS: In this prospective study, LA-NSCLC patients treated with concomitant chemoradiation underwent weekly chest-CT simulation during treatment...

Importance: Cryolipolysis is a popular, well-tolerated nonsurgical procedure that uses controlled cooling to selectively destroy fat cells. Central submental cryolipolysis has been reported to be safe and effective, but many patients would benefit from extending this treatment over the entire submental region. Objective: To investigate the safety and efficacy of cryolipolysis for reduction of lateral and central submental fat. Design, Setting, and Participants: The study population consisted of 14 participants who were treated from January 22 to June 30, 2016, in the lateral and central submental area to reduce unwanted subcutaneous fat...

To meet the requirement of high catalytic efficiency toward the reduction of p-nitrophenyl compounds, we designed a new one-dimensional Fe3O4/FeNi embedded-nanostructured catalyst synthesized by a one-pot controlling-growth-reduction process in a solvothermal system, in which Fe3O4 phase was implanted in the base of FeNi alloy. In the Fe3O4/FeNi catalyst system, the Fe3O4 embedded phase attracts the nitro group of p-nitrophenyl compounds by its high-density electrons, which can efficiently promote the activity of amorphous FeNi active centers for selective catalysis toward the reduction of a range of p-nitrophenyl compounds...

We show that hexagonal domains of monolayer tungsten disulfide (WS2) grown by chemical vapor deposition (CVD) with powder precursors can have discrete segmentation in their photoluminescence (PL) emission intensity, forming symmetric patterns with alternating bright and dark regions. Two-dimensional maps of the PL reveal significant reduction within the segments associated with the longest sides of the hexagonal domains. Analysis of the PL spectra shows differences in the exciton to trion ratio, indicating variations in the exciton recombination dynamics...

BACKGROUND: Several studies have confirmed psychiatric comorbidity and a worse quality of life in children with epilepsy, but the clinical assessment and monitoring of these patients often pays insufficient attention to their psychological aspects alongside their neurological issues. The present study aims to describe the distribution of psychopathologies and their clinical evolution over 18 months in a sample of children followed up since the onset of their epilepsy. METHODS: After being diagnosed with epilepsy, 49 subjects (age 4-18y) were followed up with psychiatric and psychological assessments based on the use of dimensional and categorical psychometric tools...

In this paper, we propose the use of local sensitivity analysis (LSA) for the structure simplification of the probabilistic neural network (PNN). Three algorithms are introduced. The first algorithm applies LSA to the PNN input layer reduction by selecting significant features of input patterns. The second algorithm utilizes LSA to remove redundant pattern neurons of the network. The third algorithm combines the proposed two and constitutes the solution of how they can work together. PNN with a product kernel estimator is used, where each multiplicand computes a one-dimensional Cauchy function...

The reaction mechanism and properties of a catalytic process are primarily determined by the interactions between reacting species and catalysts. However, the interactions are often challenging to be experimentally measured, especially for unstable intermediates. Therefore, it is of significant importance to establish an exact relationship between chemical-catalyst interactions and catalyst parameters, which will allow calculation of these interactions and thus advance their mechanistic understanding. Herein we report the description of adsorption energy on transition metals by considering both ionic bonding and covalent bonding contributions and introduce the work function as one additional responsible parameter...

Indoor positioning methods based on fingerprinting and radio signals rely on the quality of the radio map. For example, for room-level classification purposes, it is required that the signal observations related to each room exhibit significant differences in their RSSI values. However, it is difficult to verify and visualize that separability since radio maps are constituted by multi-dimensional observations whose dimension is directly related to the number of access points or monitors being employed for localization purposes...

On the way to copper(I) iodide coordination polymers with specific luminescent properties, the in situ reduction of Cu(II) in the presence of KI and bidentate N-heteroatomic ligand, either pyrazine (pyz) or 4,4'-bipyridine (bpy), resulted in one two-dimensional and two three-dimensional new coordination networks. Starting from Cu(NO3)2·3H2O in the presence of pyz, successive precipitation of known yellow [(Cu(I)I)2(pyz)]n, new orange [Cu(I)I(pyz)]n, and new dark blue {[Cu(I)(pyz)2]·I5}n polymeric solids was observed...

The ultrathin graphene metasurface is proposed as a mantle cloak to achieve wideband tunable scattering reduction around the spherical (three-dimensional) objects. The cloaking shell over the metallic or dielectric sphere is structured by a periodic array of graphene nanodisks that operate at infrared frequencies. By using the polarizability of the graphene nanodisks and equivalent conductivity method, the metasurface reactance is obtained. To achieve the cloaking shell for both dielectric and conducting spheres, the metasurface reactance as a function of nanodisks dimensions, graphene's Fermi energy, and permittivity of the surrounding areas can be tuned from the inductive to capacitive situation...

Mass cytometry by time-of-flight experiments allow analysis of over 40 functional and phenotypic cellular markers simultaneously at the single-cell level. The data dimensionality escalation accentuates limitations, inherent to manual analysis, as being subjective, labor-intensive, slow, and often incapable of showing the detailed features of each unique cell within populations. The subsequent challenge of examining, visualizing, and presenting mass cytometry data has motivated continuous development of dimensionality reduction methods...
