Exopolysaccharide from Lactobacillus plantarum HY7714 Protects against Skin Aging through Skin–Gut Axis Communication

Skin aging occurs inevitably as a natural result of physiological changes over time. In particular, solar exposure of the skin accounts for up to 90% of skin damage. Numerous studies have examined the ability of dietary constituents to prevent skin aging, and recent research has emphasized the role of functional probiotics in intestinal function and skin aging. However, the mechanism of the interactions between aging and probiotics has not been elucidated yet. The aim of this study was to determine the role of exopolysaccharides (EPS) produced by lactic acid bacteria (LAB) identified as Lactobacillus plantarum HY7714 in regulating tight junctions in intestinal epithelial cells and increasing moisture retention in human dermal fibroblasts cells. We observed that HY7714 EPS controlled intestinal tight junctions in Caco-2 cells by upregulating the genes encoding occludin-1 (OCL-1) and zonula occluden-1 (ZO-1). In addition, HY7714 EPS effectively improved UVB-induced cytotoxicity and hydration capacity in HS68 cells by downregulating production of metalloproteinases (MMPs) and reactive oxygen species (ROS). In summary, HY7714 EPS is an effective anti-aging molecule in skin and may have therapeutic potential against skin diseases and UVB-induced damage. Therefore, HY7714 EPS serves as a functional substance in skin–gut axis communication.
Relative Efficacy of High-Pressure Hot Water and High-Power Ultrasonics for Wine Oak Barrel Sanitization

A significant amount of capital and maintenance is invested in oak barrels, which contribute greatly to wine quality. If not cleaned correctly, barrels can accumulate tartrate deposits and wine spoilage organisms, which can be detrimental to wine quality. We examined the efficacy of using high-power ultrasonics (HPU) for sanitization of wine barrels using the spoilage yeast Dekkera (Brettanomyces) bruxellensis as the test organism and indirectly compared it to standard hot water washing practices. Both 1- and 3-year-old oak were investigated and no culturable cells were detected on the surface (0 to 2 mm) or subsurface (2 to 4 mm) of the oak after treatment with HPU in hot water (60°C). Additionally, wines stored over a 12-month period in barrels initially cleaned with hot water, cold water, or HPU did not differ in their extraction of oak compounds, nor could these wines be differentiated by a sensory panel. Thus, HPU did not adversely affect oak extraction into wine.
New classes of non-iterative energy corrections to multi-reference coupled-cluster energies

Two new classes of non-iterative corrections to the ground- and excited-state energies obtained in the state-universal multi-reference coupled-cluster (SUMRCC) calculations have been developed using the multi-reference extension of the method of moments of coupled-cluster equations (MMCC) [KOWALSKI, K. , and PIECUCH, P., 2001, J. molec. Struct. (THEOCHEM), 547, 191]. In the first class of the configuration interaction (CI) corrected multi-reference MMCC (MRMMCC) approximations, the non-iterative corrections due to triply or triply and quadruply excited clusters are constructed with the help of multi-reference CI (MRCI) calculations employing the same active space as used in the SUMRCC calculations. In the second class of the completely renormalized (CR) SUMRCC methods, which can be viewed as the multi-reference extensions of the single-reference CR-CCSD(T) theory [KOWALSKI, K. , and PIECUCH, P., 2000, J. chem. Phys., 113, 18], the non-iterative corrections due to triply excited clusters are constructed with the help of the multi-reference many-body perturbation theory. In both cases, the non-iterative corrections due to higher-order clusters are added to the energies obtained with the SUMRCC method with singles and doubles. It is demonstrated that the newly developed corrections, including the CR-SUMRCC methods, offer considerable improvements in the SUMRCCSD results, reducing, in particular, the large errors in the SUMRCCSD results due to intruders.
Efficiency Optimization Control of Doubly Fed Induction Generator Transitioning Into Shorted-Stator Mode for Extended Low Wind Speed Application

Transitioning a conventional doubly fed induction generator (DFIG) into a shorted-stator mode extends its operation for low wind speed power application. Since the stator of the shorted-stator mode disconnects from grid, the grid's voltages no longer contribute to building up of stator flux linkage. Stability boundaries for both modes are predicted using eigenvalue computations from steady-state models obtained from both electrical and mechanical dynamics. Propensity for instability at subsynchronous stator frequency is investigated for situations such as subsynchronous resonance. An effective control scheme that transitions the conventional DFIG to and from the shorted-stator mode is developed for loss minimization and flux weakening. Robustness of the controller to system parameter mismatch is investigated. Simulation and experimental results are presented for a 5 Hp machine.
Effects of mefenacet and pretilachlor applications on phospholipid fatty acid profiles of soil microbial communities in rice paddy soil

Abstract The effects of herbicide (mefenacet and pretilachlor) applications on soil microbial communities in rice paddy soil were investigated in a laboratory study using phospholipid fatty acid (PLFA) profiles. Soils with or without herbicide application were incubated separately under oxidative or reductive conditions for 30 d. Half-life (DT50) of mefenacet was 14 d under oxidative conditions and 9.8 d under reductive conditions. DT50 of pretilachlor was 17 d under oxidative conditions and 8.8 d under reductive conditions. PLFA contents did not seem to be affected by the residual levels of herbicides. The composition of PLFAs under in both the oxidative and reductive conditions fluctuated during the incubation period. However, the effects of applications of herbicides (mefenacet and pretilachlor) under oxidative and reductive conditions in rice paddy soil did not affect appreciably the soil microbial biomass and the structure of the soil microbial communities, as determined by PLFA profiles. Fluctuations in the composition of PLFAs during the incubation period were rather conspicuous.
Extraction of Europium(III) into W/O Microemulsion Containing Aerosol OT and a Bulky Diamide. I. Cooperative Effect

Abstract The extraction of Eu(III) from aqueous HNO3 solution into a water‐in‐oil (W/O) microemulsion occurring in hexane was studied. Aerosol OT (AOT−) was used as an anionic surfactant, and a bulky diamide (DA), N,N ′‐dioctyl‐N,N ′‐dimethyl‐2‐(3′‐oxapentadecyl)propane‐1,3‐diamide, was employed as an electrically neutral extractant. The combination of AOT− and the DA shows a very strong cooperative effect on the metal extraction. The microemulsion containing AOT− alone in hexane, equilibrated with the acidic solution, is unstable. However, in the presence of the electrically neutral extractant acting as a “masking” ligand to H+, the microemulsion in the hexane phase is dramatically stabilized, which enhances the distribution of Eu(III) to the organic phase. The distribution of the metal in the micellar extraction system is also greatly affected by the concentration of an electrolyte, such as HNO3 or NaNO3, playing two important roles, i.e., the formation of the microemulsion, “promoting” the metal extraction, and the ion‐exchange of the metal ion for the cation yielded from the electrolyte, contrarily, “suppressing” the metal extraction.
PMSM Design for Achieving a Target Torque-Speed-Efficiency Map

During the last years, the requirements for a fast and reliable design of electrical machines by applying optimization methods using finite element analysis (FEA), has become a subject of study. Due to their capabilities, permanent magnet synchronous machines (PMSMs) have become the preference choice for many applications, including electric vehicles (EVs) propulsion, water-pumping, robotics, or renewable power generation among others. This paper presents a novel methodology for designing and optimizing PMSMs using the torque-speed-efficiency map. The design-optimization algorithm requires as input, the torque-speed-efficiency map of the target motor, to define the required performance for the given application. The objective is to find the motor geometry which better approximates the target torque-speed-efficiency map. The PMSM is evaluated by using magneto-static FEA combined with direct-quadrature (d-q) electrical modeling, thus greatly reducing the computational burden when compared to conventional time-dependent FEA methods. The magneto-static FEA method calculates iron losses taking into account the magnetic flux density harmonic content by applying a time-space conversion approach. The design-optimization process takes into account the control strategy as well as losses separation, which is validated by using the public experimental data of the Toyota Prius and Camry PMSMs.
Retrieving Soil Moisture Over Soybean Fields During Growing Season Through Polarimetric Decomposition

Soil moisture (Mv) estimation and monitoring over agricultural areas using Synthetic Aperture Radar (SAR) are often affected by vegetation cover during the growing season. Volume scattering and vegetation attenuation can complicate the received SAR backscatter signal when microwave interacts with the vegetation canopy. To address the existing problems, this article employed the model-based polarimetric decomposition method considering the two-way attenuation to remove the volume scattering and vegetation attenuation. A deorientation process of SAR data was applied to remove the influence of randomly distributed target orientation angles before the polarimetric decomposition. To parameterize the two-way attenuation, Radar Vegetation Index derived from the SAR intensity images was adopted. The Dubois model was used to describe backscattering from the underlying bare soil. Since the soil roughness parameters are difficult to measure under vegetation cover, the optimum surface roughness method was used to parameterize the Dubois model. This soil moisture retrieval algorithm was applied to the polarimetric multitemporal RADARSAT-2 SAR data over soybean fields. The validation indicates the root-mean-square error of 9.2 vol.% and 8.2 vol.% at HH and VV polarization, respectively, over the entire soybean growing period, suggesting that the proposed method is capable of reducing the effect of vegetation cover for soil moisture monitoring over the soybean field.
A Brief Note on Molecular Oncology

Cancer prevalence and deaths are high in developing nations, wherever resources for cancer control are inadequate. About one-quarter of cancers in resource-limited countries are infection related, and molecular tests can capitalize on this relationship by recognizing germane pathogen genomes and human gene variations to distinguish those at highest risk for progression to cancer, to classify lesions, to predict effective therapy, and to monitor tumour burden over time. Prime cases are human papillomavirus in cervical neoplasia, Helicobacter pylori and Epstein-Barr infection in gastric adenocarcinoma and lymphoma, and hepatitis B or C virus in hepatocellular cancer. Research is underway to engineer devices that overcome social, financial, and technical barriers restricting viable laboratory support. Extra challenges incorporate an educated workforce, infrastructure for quality metrics and record keeping, and funds to sustain molecular test services. The combination of well-designed interfacing, novel and vigorous electrochemical innovation, and telemedicine devices will promote adoption by frontline providers. Quick turnaround is crucial for surmounting loss to follow-up, although increased utilize of cell phones, even in rural regions, improves choices for patient education and engagement. Links to a broadband network facilitate discussion and centralized capacity of restorative information. Molecular technology appears guarantee to address crevices in health care through quick, user-friendly, and cost-effective devices reflecting clinical priorities in resource-poor regions.

A conformational study of peptides with the general structure Ac-L-Xaa-Pro-D-Xaa-L-Xaa-NH2: spectroscopic evidence for a peptide with significant .beta.-turn character in water and in dimethyl sulfoxide

Several tetrapeptides, Ac-Val-Pro-D-Ser-His-NH_2, in particular, show significant type II β-turn character in water and in dimethyl sulfoxide. Evidence for this turn population is provided by 2D-rotating frame nuclear Overhauser effect (ROESY) spectroscopy, ^1H NMR amide temperature coefficients, and circular dichroism (CD) studies. To further investigate which residues specifically contribute to the integrity of the turn, studies on 10 tetrapeptides, having the general sequence AC-LXaa-Pro-D-Xaa-L-Xaa-NH_2, are described. The results show the effects of sequence variations on the type II β-turn forming propensity of these peptides in solution. Conclusions from these studies indicate that a cooperative effect between a sterically hindered, β-branched amino acid at the (i) position and a small, non-β-branched D-amino acid at the (i+2) position promotes turn formation. Implications for use of these sequences as structural nucleation elements in de novo protein design are discussed.
The Level of Practicing the Requirements of Active Learning by Islamic Education Teachers Enrolled at King Khalid University in Asir Region

This study identified the level of practicing the requirements of active learning by Islamic education teachers studying at King Khalid University. (28) teachers from the eighth level in the Faculties of Education and Sharia participated in this study. The study used the descriptive approach and developed a study tool, which is a note card consisting of (25) statements that measure the practices of Islamic education teachers for the requirements of active learning. After analyzing the data, the results showed that the level of practicing the requirements of active learning by Islamic education teachers was average. The findings showed statistically significant differences between the mean scores of Islamic education teachers' practice of active learning styles due to the variable of the educational stage in favor of the primary stage. In light of the results of the research, it is recommended to conduct training courses for Islamic education teachers on active learning before and during service. The study recommended introducing Islamic education teachers working in the field to active learning strategies in teaching, and its importance, by providing educational documentaries and publications. There is a need to include methods of applying active learning strategies in Islamic education teachers' guidebooks.
A new approach for the formulation of beverages. I. Sensory exploration of a composition space by trained and consumer panellists.

Abstract The aim of the paper is to present the methodology and the results of a sensory study for the formulation of new beverages. The method consists of several steps. A composition space is first defined by choosing the nature and concentration range of seven ingredients. Eighty-one mixtures, differing in the concentration of four ingredients which vary at three concentration levels, are formulated and examined from a sensory point of view. A sensory profile is performed by a panel of trained judges. Five sensory attributes chosen for their high discrimination capacity and their significant action in predicting ingredient variations are selected. Six products differing in their sensory properties are selected in the sensory space and tasted by 111 consumers. The panellists are clustered into three groups of homogeneous preference. Thirty consumers showing a preference for the same product as well as the five descriptors are used as inputs for the interactive optimization of the product formulation which is described in part II of this article.
Biological Techniques for Determining Relative Soft-Rot Attack in Hardwoods

Determination of Cx-cellulase activity of soft-rotted wood samples showed good correlations with other techniques for estimating biological attack in hardwoods. Optimal pH and temperature Parameters of the test were studied. The assay can be used for the quick assessment of the cellulase activity of bulk samples. The method has been found to be more sensitive in detecting incipient soft-rot than other current methods and therefore may be useful in determining the relative effectiveness of preservatives in field trials. Estimations of fungal activity in wood by an agar plate method was of some value.

So that the activity of biological agents on humus soil with infiltration levels will be optimal on the 30th day.
Automatic corrections of human body depth maps using deep neural networks

This paper presents an approach to correcting misclassified pixels in depth maps representing parts of the human body. A misclassified pixel is a pixel of a depth map which, incorrectly, has the ? background? value and does not accurately reflect the distance from the sensor to the body being scanned. A completely automatic, deep learning based solution for depth map correction is proposed. As an input, the solution requires a color image and a corresponding erroneous depth map. The input color image is segmented using deep neural network for human body segmentation. The extracted segments are further used as guidance to find and amend the misclassified pixels on the depth map using a simple average based filter. Unlike other depth map refinement solutions, this paper designs a method for the improvement of the input depth map in terms of completeness instead of precision. The proposed method does not exclude the application of other refinement methods. Instead, it can be used as the first step in a depth map enhancement pipeline to determine approximate depths for erroneous pixels, while other refinement methods can be applied in a second step to improve the accuracy of the recovered depths.
Effects of hydrogen incorporation in GaMnN

Single-phase (Ga,Mn)N layers grown by molecular beam epitaxy with ∼3 at. % Mn were exposed to 2H or 1H plasmas under conditions designed to permeate layers with hydrogen. No evidence of the formation of Mn–H complexes could be detected from either infrared spectroscopy or the changes in magnetic properties. However, the residual magnetization increased ∼20% after hydrogenation, consistent with passivation of crystal defects in (Ga,Mn)N. Hydrogenation may be an attractive method for improving the magnetic properties of these heteroepitaxial materials.
THE POSITIONING OF STREET NAMES ON EGOCENTRICALLY REFERENCED MAPS: ASSESSMENT OF READING TIME

Abstract: The main objective of this research is to evaluate the reading time of street names on dynamic egocentrically referenced maps for In-Car Route Guidance and Navigation Systems. Two different road network patterns (grid-like or non-grid-like) were considered and tasks were devised to search for street names in two different route segments (where the driver was, or where the driver would have to manoeuvre). Considering a non-grid-like road network pattern, for the task of searching for the name of a road where the driver would manoeuvre, street names aligned horizontally and next to the route were read significantly faster than street names positioned along the route. Street names positioned obliquely required more reading time than street names aligned horizontally. Dynamic maps egocentrically referenced should present street names horizontally aligned and next to the route for the segment related to where the driver will manoeuvre, for both road network patterns. Also, Street names should be positioned next to the car symbol.
CO adsorption on close-packed transition and noble metal surfaces: trends from ab initio calculations

We have studied the trends in CO adsorption on close-packed metal surfaces: Co, Ni, Cu from the 3d row, Ru, Rh, Pd, Ag from the 4d row and Ir, Pt, Au from the 5d row using density functional theory. In particular, we were concerned with the trends in adsorption energy, geometry, vibrational properties and other parameters derived from the electronic structure of the substrate. The influence of specific changes in our set-up, such as choice of the exchange correlation functional, the choice of pseudopotential, size of the basis set and substrate relaxation, has been carefully evaluated. We found that, while the geometrical and vibrational properties of the adsorbate–substrate complex are calculated with high accuracy, the adsorption energies calculated with the gradient-corrected Perdew–Wang exchange–correlation energies are overestimated. In addition, the calculations tend to favour adsorption sites with higher coordination, resulting in the prediction of the wrong adsorption sites for the Rh, Pt and Cu surfaces (hollow instead of top). The revised Perdew–Burke–Erzernhof functional (RPBE) leads to lower (i.e. more realistic) adsorption energies for transition metals, but to the wrong results for noble metals—for Ag and Au, endothermic adsorption is predicted. The site preference remains the same. We discuss trends in relation to the electronic structure of the substrate across the periodic table, summarizing the state-of-the-art of CO adsorption on close-packed metal surfaces.
Vibrations of Long Chain Molecules; Raman Spectra of n‐Octane, Decane, Cetane and Eicosane in the Liquid State

The Raman spectra of n‐octane, decane, cetane and eicosane in the liquid state have been photographed. With increasing chain length the low‐lying Raman lines (< 800 cm—1) become few in number and very diffuse. This observation is interpreted in terms of a number of chain configurations co‐existing in the liquid state in contrast to the extended configuration found by x‐ray analysis of crystalline paraffins. Theoretical investigations which assume that the carbon atoms in a chain are coplanar are not applicable to data obtained for liquid (and gaseous) paraffins.
