Effects of maternal supplementation of fish oil during late gestation and lactation on growth performance, fecal microbiota structure and post-weaning diarrhoea of offspring piglets

Abstract Homeostasis of gut microbiota is a critical contributor to growth and health in weaned piglets. Fish oil is widely reported to benefit health of mammals including preventing intestinal dysfunction, yet its protective effect during suckling-to-weaning transition in piglets remains undetermined. Low (30 g/d) and high (60 g/d) doses of n-3-rich fish oil were supplemented in sows from late gestation to lactation. Serum indicators and gut microbiota were determined to evaluate the effects of maternal fish oil on growth performance, immunity and diarrhea of piglets. DHA and EPA in the colostrum as well as serum of suckling and 1-week post-wean piglets were significantly and linearly increased by maternal supplementation of fish oil (P < 0.05). IGF1 and T3 in nursing and weaned piglets were significantly elevated by maternal fish oil (P < 0.05), and the increase of IGF1 was concerning the dosage of fish oil. Colostrum IgG, plasma IgG, IgM in suckling piglets, IgG, IgM and IgA in weaned piglets were significantly increase as maternal replenishment of fish oil increased (P < 0.05). Additionally, cortisol was significantly reduced in weaned pigs (P < 0.05), regardless of dosage. 16S rRNA sequencing revealed that α-diversity of fecal microbiota in nursery piglets, and fecal Lactobacillus genus, positively correlated with post-weaning IgA, was significantly increased by high dosage. Collectively, maternal fish oil during late pregnancy and lactation significantly promoted growth, enhanced immunity, and reduced post-weaning diarrhea in piglets, therefore facilitated suckling-to-weaning transition in piglets, which may be partially due to the altered gut microbial community.
Use of Customized Employment in State Vocational Rehabilitation Programs: A Retrospective Study 2017–2020

The purpose of this study was to examine the outcomes of customized employment via an analysis using the U.S. Rehabilitation Services Administration Case Service Report (RSA-911) from Federal Fiscal Years of 2017 through 2020. The independent variables were demographics, barriers to employment, and types of state vocational rehabilitation agency (SVRA) services, and the dependent variables were competitive integrated employment status and weekly earnings at exit. Descriptive analyses, multiple logistic regression, and hierarchical multiple regression comprised data analysis. The study sample (N = 2,280) was 57.9% male and 42.1% female and had a mean age of 32.69 years (SD = 12.83). Seventy-seven percent identified themselves as White and 46.7% had a cognitive disability. The results of this study indicated that consumers who have cognitive disability and cultural barriers; are migrant farmworkers and/or dependents; and receive job placement assistance, short-term job supports, maintenance services, benefits counseling, and supported employment are more likely to get competitive integrated employment at exit (R2 = .34). Multiple variables were found to be significantly related to weekly earnings at exit and explained 24% of the variance. Rehabilitation counselors should take into consideration the findings of this study to determine from which supports consumers may benefit to attain successful employment goals, particularly for customized employment.
Magnetohydrodynamic instabilities in radial foil configurations

While detrimental to plasma performance, magnetohydrodynamic plasma instabilities in radial foil configurations do not preclude intense x-ray radiations from the central plasma column. As most of the plasma current flows there, the column pinches generating x-rays. However, pinch comes with a kink instability which twists the column and prevents homogeneous compression. This instability leads to the disruption of the plasma bubble surrounding the central plasma column. Loss of symmetry in the resulting plasma expansion has been recorded. It is possible to reduce the impact of instabilities by increasing the initial plasma mass. The central column can also be stabilized by using a central rod, delaying the formation of the kink.
Dissecting the general mechanisms of protein cage self‐assembly by coarse‐grained simulations

The development of artificial protein cages has recently gained massive attention due to their promising application prospect as novel delivery vehicles for therapeutics. These nanoparticles are formed through a process called self‐assembly, in which individual subunits spontaneously arrange into highly ordered patterns via non‐covalent but specific interactions. Therefore, the first step toward the design of novel engineered protein cages is to understand the general mechanisms of their self‐assembling dynamics. Here we have developed a new computational method to tackle this problem. Our method is based on a coarse‐grained model and a diffusion–reaction simulation algorithm. Using a tetrahedral cage as test model, we showed that self‐assembly of protein cage requires of a seeding process in which specific configurations of kinetic intermediate states are identified. We further found that there is a critical concentration to trigger self‐assembly of protein cages. This critical concentration allows that cages can only be successfully assembled under a persistently high concentration. Additionally, phase diagram of self‐assembly has been constructed by systematically testing the model across a wide range of binding parameters. Finally, our simulations demonstrated the importance of protein's structural flexibility in regulating the dynamics of cage assembly. In summary, this study throws lights on the general principles underlying self‐assembly of large cage‐like protein complexes and thus provides insights to design new nanomaterials.
Development and Characterizations of Novel Aqueous-Based Ceramic Inks for Inkjet Printing

Stable rheological properties of ceramic ink are a key requirement for inkjet printing (IJP), which should be satisfied in terms of the Reynolds and Weber numbers. In this paper, the reverse microemulsion was introduced for the synthesis of monodispersed nanosized ceramic powders, and the average size was less than 100 nm. A comparison of two different dispersants, i.e., polyacrylic ammonium (PAANH4) and polyacrylic aid (PAA), revealed that the former exerted a good dispersion effect on the ceramic ink. The sedimentation ratio, zeta potential, surface tension, viscosity, and density of the inks were measured, and the Reynolds and Weber numbers, as well as Z value, were calculated. A stable, homogeneous, and high solid loading (20 wt%) ceramic ink could be achieved after aging for a period of 72 h. Finally, the ceramic inks showed the desired printable property in the inkjet printing process. Combining inkjet printing technology with a sintering process, Ni-Mn-O films have the potential to monitor temperature and humidity parameters for intelligent wearable devices.
UHPLC-MS Chemical Fingerprinting and Antioxidant, Enzyme Inhibition, Anti-Inflammatory In Silico and Cytoprotective Activities of Cladonia chlorophaea and C. gracilis (Cladoniaceae) from Antarctica

The lichen species Cladonia chlorophaea and C. gracilis (Cladoniaceae) are widely distributed in the island archipelago of maritime Antarctica and represent a natural resource of scientific interest. In this work, the metabolomic characterization of the ethanolic extracts of these species and the determination of the antioxidant activity, enzymatic inhibition and anti-inflammatory potential of selected compounds on the 5-lipoxygenase enzyme by molecular docking and cytoprotective activity in the SH-SY5Y cell line were carried out. Nineteen compounds were identified by liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UHPLC-ESI-QTOF-MS) in each of the species. The contents of phenolic compounds, antioxidant activity, the inhibition of cholinesterases (acetylcholinesterase and butyrylcholinesterase) and digestive enzymes (α-glucosidase and pancreatic lipase) were variable among species, with better results in C. chlorophaea. Molecular docking evidenced significant binding affinities of some compounds for the 5-lipoxygenase enzyme, together with outstanding pharmacokinetic properties. Both extracts were shown to promote cell viability and a reduction in reactive oxygen species production in an H2O2-induced oxidative stress model. This study contributes to the chemical knowledge of the Cladonia species and demonstrates the biological potential for the prevention and promising treatment of central nervous system pathologies, inflammatory disorders and metabolic alterations.
Direction finding with an array of antennas having diverse polarizations

The advantages of using diversely polarized antennas to determine bearings of multiple cochannel narrow-band signals are shown. Three bearing estimation algorithms-maximum likelihood (ML), adapted angular response (AAR), and Music (multiple signal classification)-are extended to handle antenna arrays with diverse polarizations; the maximum entropy method does not readily extend. The proposed algorithms are applicable to arbitrary antenna locations and directional characteristics and arbitrary noise correlations between the antenna outputs. The algorithms are compared on the basis of multiple signal resolution and bearing accuracy in the presence of noise. The Music algorithm exhibits superior performance at moderate to low signal-to-noise ratio (SNR).
Finite Difference Time Domain (Fdtd) Impedance Boundary Condition for Thin Finite Conducting Sheets- Abstract

A new Impedance Boundary Condition (IBC) for two dimensional Finite Difference Time Domain simulations containing thin, good conductor sheets is presented. The IBC uses a recursive convolution scheme based on approximating the conductor's impedance as a sum of exponentials. The effects of FDTD parameters such as grid size and time step on simulation accuracy are presented. The IBC verification is performed by comparing the quality factors of rectangular resonant structures determined by the FDTD simulation and analytical methods. The IBC is shown to accurately model the conductor loss over a wide frequency range.

The active region is based on a bound-to-continuum transition combined with an optical phonon extraction. The optical waveguide exploits a combination of metallic and dielectric confinement. Threshold current density of 460A∕cm2 at 10K and a maximum operating temperature of 45K are achieved.
The Effect of Bedrock Differences on Plant Water Use Strategies in Typical Karst Areas of Southwest China

Moisture conditions are important ecological factors limiting plant growth in karst areas. In karst areas, because bedrock exposure and permeability are significant and soils are dispersed—without spatial continuity—and shallow, the water storage required for plant uptake and growth in rock fissures as well as shallow soils is very limited, and therefore, water conditions are an important factor influencing plant growth. In order to discover the sources of water used by plants in the karst zone ecosystem of southwest China and the differences in plant water use under different lithological conditions, this study selected limestone and dolomite in the karst ecological test site of Maocun, Guilin, Guangxi, for comparison with the clastic rock area. By measuring the δD and δ18O composition of plant stem water and the potential water sources (soil water, groundwater and precipitation) of the dominant species in the study area, and using the IsoSource and soil water excess (SW-excess) models, we analyzed the proportion of water utilization by different vegetation types under different lithological conditions. The results showed that (1) the slope and intercept of the local rainfall line (LMWL) and soil water line (SWL) in the study area were smaller than those of the global rainfall line (GMWL), and also smaller than those of the local atmospheric precipitation line in Guilin (δD = 8.8δ18O + 17.96), indicating that the local rainfall is influenced by evaporation and is formed by nonequilibrium fractionation of isotopes; (2) in general, the plant water sources in the dolomite, limestone, and clastic areas were dominated by rainfall, groundwater, and soil water, respectively; and (3) the fluctuation range of SW-excess in karst areas was significantly greater than that in nonkarst areas, the xylem water of plants in karst areas was more depleted in δD than soil water, and groundwater was more enriched in δD than soil water, indicating that there might be an ecological–hydrological separation phenomenon in karst areas, i.e., the “two water worlds” hypothesis. The results of this study provide scientific data for hydrological regulation in the ecological restoration of karst areas.
Passivity-based control of spatially discretized port-Hamiltonian system

Abstract The main contribution of this paper is a procedure for the passivity-based control of high-order port-Hamiltonian systems obtained from the spatial discretization of infinite dimensional dynamics. Beside the intrinsic difficulties related to the large number of state variables, the finite element model is generally given in terms of a Dirac structure and is completely a-causal, which implies that the plant dynamics is not given in standard input-state-output form, but as a set of DAEs. Consequently, the passivity-based methods have to be extended in order to deal with dynamical systems with constraints, usually appearing in the form of Lagrangian multipliers.
The global burden of Chikungunya fever among children: A systematic literature review and meta-analysis

Chikungunya fever (CHIKF) is an arboviral illness that was first described in Tanzania (1952). In adults, the disease is characterised by debilitating arthralgia and arthritis that can persist for months, with severe illness including neurological complications observed in the elderly. However, the burden, distribution and clinical features of CHIKF in children are poorly described. We conducted a systematic literature review and meta-analysis to determine the epidemiology of CHIKF in children globally by describing its prevalence, geographical distribution, and clinical manifestations. We searched electronic databases for studies describing the epidemiology of CHIKF in children. We included peer-reviewed primary studies that reported laboratory confirmed CHIKF. We extracted information on study details, sampling approach, study participants, CHIKF positivity, clinical presentation and outcomes of CHIKF in children. The quality of included studies was assessed using Joanna Briggs Institute Critical Appraisal tool for case reports and National Institute of Health quality assessment tool for quantitative studies and case series. Random-effects meta-analysis was used to estimate the pooled prevalence of CHIKF among children by geographical location. We summarised clinical manifestations, laboratory findings, administered treatment and disease outcomes associated with CHIKF in children. We identified 2104 studies, of which 142 and 53 articles that met the inclusion criteria were included in the systematic literature review and meta-analysis, respectively. Most of the selected studies were from Asia (54/142 studies) and the fewest from Europe (5/142 studies). Included studies were commonly conducted during an epidemic season (41.5%) than non-epidemic season (5.1%). Thrombocytopenia was common among infected children and CHIKF severity was more prevalent in children <1 year. Children with undifferentiated fever before CHIKF was diagnosed were treated with antibiotics and/or drugs that managed specific symptoms or provided supportive care. CHIKF is a significant under-recognised and underreported health problem among children globally and development of drugs/vaccines should target young children.
Electrohydrodynamic quenching in polymer melt electrospinning

Infrared thermal measurements on polymer melt jets in electrospinning have revealed rapid quenching by ambient air, an order of magnitude faster than predicted by the classical Kase and Matsuo correlation. This drastic heat transfer enhancement can be linked to electrohydrodynamic (EHD) effects. Analysis of EHD-driven air flow was performed and included into a comprehensive model for polymer melt electrospinning. The analysis was validated by excellent agreement of both predicted jet radius and temperature profiles with experimental results for electrospinning of Nylon-6 (N6), polypropylene (PP), and polylactic acid (PLA) melts. Based on this analysis, several methods that can be used to inhibit or enhance the quenching are described.
Some Debye Temperatures from Single‐Crystal Elastic Constant Data

The mean velocity of sound has been calculated for 14 crystalline solids by using the best recent values of their single‐crystal elastic stiffness constants. These mean sound velocities have been used to obtain the elastic Debye temperatures θDe for these materials. Models of the three wave velocity surfaces for calcite are illustrated.
ATOM PROBE ANALYSIS OF FE73.5SI13.5B9NB3CU1 NANOCRYSTALLINE SOFT MAGNETIC MATERIAL

The microstructure of Fe73.5Si13. 5B9Nb3Cu1 soft magnetic material with a nanocrystalline structure has been investigated by atom probe field ion microscopy. In the as‐quenched amorphous sample, all the alloying elements were found to distribute homogeneously as an amorphous solid solution. In the annealed sample with the optimum soft magnetic properties, we found that two phases were present. One was Fe‐Si solid solution and the other was the B‐ and Nb‐enriched region with less Si content. Although some uncertainty remains regarding Cu, the present result is consistent with an early speculation based on the lattice parameter measurement.
Relative abundance of single and double vacancies in irradiated single-walled carbon nanotubes

Double and single vacancies differently affect the conductance of carbon nanotubes [G. Gomez-Navarro et al., Nat. Mater. 4, 534 (2005)], so that the exact knowledge of the abundance of these defects is mandatory for an unambiguous interpretation of irradiation-induced changes in nanotube conductance. We calculate concentrations of defects produced by Ar ions using the molecular dynamics method combined with kinetic Monte Carlo simulations. Carefully taking into account the annealing of defects, we show that the ratio of single to double vacancies has a minimum at ion energies of about 0.5keV and that the ratio saturates toward a constant value at high ion energies.
Initiation of an early-stage plasma during picosecond laser ablation of solids

Picosecond time-resolved images of plasma initiation were recorded during pulsed-laser ablation of metal targets in an air atmosphere. An early-stage plasma was observed to form before the release of a material vapor plume. Close to the target surface, interferometry measurements indicate that the early-stage plasma has an electron number density on the order of 1020 cm−3. The longitudinal expansion of the ionization front for this plasma has a velocity 109 cm/s, during the laser pulse. In contrast, a material–vapor plume forms approximately 200 ps after the laser pulse, and it moves away from the target at 106 cm/s. The experimental observations of the early-stage plasma were simulated by using a theoretical model based on a two-fluids description of laser plasmas. The results indicate that the initiation of the plasma is due to air breakdown assisted by electron emission from the target.
Toward Predictive Modeling of Solar Power Generation for Multiple Power Plants

SUMMARY Solar power is the most widely used renewable energy source, which reduces pollution consequences from using conventional fossil fuels. However, supplying stable power from solar power generation remains challenging because it is difficult to forecast power generation. Accurate prediction of solar power generation would allow effective control of the amount of electricity stored in batteries, leading in a stable supply of electricity. Although the number of power plants is increasing, building a solar power prediction model for a newly constructed power plant usually requires collecting a new training dataset for the new power plant, which takes time to collect a sufficient amount of data. This paper aims to develop a highly accurate solar power prediction model for multiple power plants available for both new and existing power plants. The proposed method trains the model on existing multiple power plants to generate a general prediction model, and then uses it for a new power plant while waiting for the data to be collected. In addition, the proposed method tunes the general prediction model on the newly collected dataset and improves the accuracy for the new power plant. We evaluated the proposed method on 55 power plants in Japan with the dataset collected for two and a half years. As a result, the pre-trained models of our proposed method significantly reduces theaverageRMSEofthebaselinemethodby73.19%. Thisindicatesthatthe modelcangeneralizeovermultiplepowerplants, andtrainingusingdatasets from other power plants is effective in reducing the RMSE. Fine-tuning the pre-trained model further reduces the RMSE by 8.12%.
EFFECT OF CALCIUM SALTS ON GROWTH , SCLEROTIA AND INFECTIVITY OF Sclerotinia sclerotiorum

: The objective of this work was to study the effects of calcium salts on growth, sclerotia production, carpogenic germination and infectivity of Sclerotinia sclerotiorum (Lib.) de Bary ascospores. Morphological and pathological variability was induced to the fungus by calcium salts. Effects of calcium were varied with various calcium forms and their concentrations tested. Calcium acetate was the most effective to inhibit growth of the fungus, which expressed as linear growth on agar medium or mycelial dry weight onto liquid medium. On the other hand, calcium phosphate showed the highest inhibitory effect toward sclerotia production by the tested fungus grown onto either solid or liquid media. Since it caused 75% inhibition for sclerotia production at 4000 ppm and completely prevented sclerotia production at 8000 ppm. Otherwise, calcium chloride provided the highest inhibitory effect to carpogenic germination. Also, number of apothecia was greatly affected by calcium acetate, calcium oxide and calcium carbonate. Moreover, infectivity of S. sclerotiorum ascospores was varied with calcium salts tested. Calcium phosphate and calcium oxide were the most suppressive to ascospores infectivity.
Selective growth of catalyst-free ZnO nanowire arrays on Al:ZnO for device application

Vertically aligned ZnO nanowire (NW) arrays have been synthesized selectively on patterned aluminum-doped zinc oxide (AZO) layer deposited on silicon substrates without using any metal catalysts. The growth region was defined by conventional photolithography with an insulating template. Careful control of the types of template materials and growth conditions allows good alignment and growth selectivity for ZnO NW arrays. Sharp ultraviolet band-edge peak observed in the photoluminescence spectra of the patterned ZnO NW arrays reveals good optical qualities. The current-voltage characteristics of ZnO NWs∕AZO∕p-Si device suggest that patterned and aligned ZnO NW arrays on AZO may be used in optoelectronic devices.
