description: Six forest stands of 59, 34 and 24 year-old Pinus massoniana forests and their mixed forests were selected at the Experimental Center of Tropical Forestry of Chinese Academy of Forestry, and 20 m × 20 m plot was set up and soil samples were taken from 0-60 cm soil layers, to analyze the changes of soil nutrient content under different forest stands and forest ages. The results showed that soil moisture and the bulk density in the mesophytic forest land were higher than those of other forest lands. The highest soil porosity value was observed in the early forest land. Soil pH of different forest ranged from 4.45 to 4.75, indicating the variation was small. Besides, it indicated that the mixed forest was more able to increase the soil fertility than the pure forest because that the variation of soil acidity, organic matter content and total P and K in 34 and 24 year-old mixed forests were higher than those in pure forests of the same year old. However, the content of soil available P and K decreased with the increase of soil depth, and varied in terms of forest ages. From the changes of soil indicators in different forest lands, soil nutrients in the 34 year-old P. massoniana forest was superior to that of other forest stands.

description: In this talk, I report on three theorems concerning algebraic varieties over a field of characteristic $p>0$. a) over a finite field of cardinal $q$, two proper smooth varieties which are geometrically birational have the same number of rational points modulo $q$ (cf. Ekedahl, 1983). b) over a finite field of cardinal $q$, a proper smooth variety which is rationally chain connected, or Fano, or weakly unirational, has a number of rational points congruent to 1 modulo $q$ (Esnault, 2003). c) over an algebraic closed field of caracteristic $p>0$, the fundamental group of a proper smooth variety which is rationally chain connected, or Fano, or weakly unirational, is a finite group of order prime to $p$ (cf. Ekedahl, 1983). The common feature of the proofs is a control of the $p$-adic valuations of Frobenius and is best explained within the framework of Berthelot's rigid cohomology. I also explain its relevant properties.

description: Funder: Isaac Newton Trust (GB)
description: Abstract: Background: Growing evidence points towards a role of gastrointestinal (GI) helminth parasites of ruminants in modifying the composition of the host gut flora, with likely repercussions on the pathophysiology of worm infection and disease, and on animal growth and productivity. However, a thorough understanding of the mechanisms governing helminth-microbiota interactions and of their impact on host health and welfare relies on reproducibility and replicability of findings. To this aim, in this study, we analysed quantitative and qualitative fluctuations in the faecal microbiota composition of lambs vaccinated against, and experimentally infected with, the parasitic GI nematode Teladorsagia circumcincta over the course of two separate trials performed over two consecutive years. Methods: Two trials were conducted under similar experimental conditions in 2017 and 2018, respectively. In each trial, lambs were randomly assigned to one of the following experimental groups: (i) vaccinated/infected, (ii) unvaccinated/infected and (iii) unvaccinated/uninfected. Faecal samples collected from individual animals were subjected to DNA extraction followed by high-throughput sequencing of the V3-V4 region of the bacterial 16S rRNA gene and bioinformatics and biostatistical analyses of sequence data. Results: Substantial differences in the populations of bacteria affected by immunisation against and infection by T. circumcincta were detected when comparing data from the two trials. Nevertheless, the abundance of Prevotella spp. was significantly linked to helminth infection in both trials. Conclusions: Despite the largely conflicting findings between the two trials, our data revealed that selected gut microbial populations are consistently affected by T. circumcincta infection and/or vaccination. Nevertheless, our study calls for caution when interpreting data generated from in vivo helminth-microbiome interaction studies that may be influenced by several intrinsic and extrinsic host-, parasite- and environment-related factors.

description: We introduce a $p_{z}-d$ coupling model Hamiltonian for the $π$-graphene/Au bands that predicts a rather large intrinsic spin-orbit (SO) coupling as are being reported in recent experiments and DFT studies. Working within the analytical Slater-Koster tight-binding approach we were able to identify the overlapping orbitals of relevance in the enhancement of the SO coupling for both, the sublattice symmetric (BC), and the ATOP (AC) stacking configurations. Our model effective Hamiltonian reproduces quite well the experimental spectrum for the two registries, and in addition, its shows that the hollow site configuration (BC), in which the A/B sites remain symmetric, yields the larger increase of the SO coupling. We also explore the Au-diluted case keeping the BC configuration and showed that it renders the preservation of the SO-gap with a similar SO interaction enhancement as the undiluted case but with a smaller graphene-gold distance.

description: A numerical study on the elastic response of single- and multi-layer systems formed by alternating pentamode lattices and stiffening plates is presented. Finite element simulations are conducted to analyze the dependence of the effective elastic moduli of such structures upon suitable aspect ratios, which characterize the geometry of the generic pentamode layer at the micro- and macro-scale, and the lamination scheme of the layered structure. The given numerical results highlight that the examined structures exhibit bending-dominated response, and are able to achieve low values of the effective shear modulus and, contemporarily, high values of the effective compression modulus. We are lead to conclude that confined pentamode lattices can be regarded as novel metamaterials that are well suited for seismic isolation and impact protection purposes. Their elastic response can be finely tuned by playing with several geometrical and mechanical design variables.

description: This paper first elaborated the purpose of accelerating the greening process, improving the landscape effect, and improving the ecological environment for transplanting large trees to cities. Then, it introduced main problems: destroying the ecological environment of the producing area, damaging the entire ecosystem, increasing the cost of social greening, and seriously wasting forest resources. It analyzed the reasons for these problems, including the imperfect laws and regulations, blind and not scientific transplanting, and eagerness for quick success. Finally, it came up with recommendations including improving policies and regulations, reinforcing technical specifications, and first pseudo planting then field planting, and setting up the overall point of view.

description: [Objectives] To explore the inhibitory effects of Prunus mume, Coptis chinensis, and Crataegus pinnatifida on Vibrio alginolyticus and its biofilm in vitro. [Methods] The agar diffusion method was applied to determine the inhibition zone diameter of three Chinese herbal medicines on V. alginolyticus; double dilution method was used to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of three Chinese herbal medicines on V. alginolyticus; methylthiazolyl tetrazolium (MTT) method was applied to evaluate the effects of three Chinese herbal medicines on the biofilm formation of V. alginolyticus. [Results] The three Chinese herbal medicines had different inhibitory effects on V. alginolyticus. The inhibition zones of P. mume, C. chinensis, and C. pinnatifida on V. alginolyticus were (18.31 ± 0.29) mm, (20.31 ± 0.30) mm, and (30.24 ± 0.14) mm respectively, and P. mume had strong bacteriostatic effects on V. alginolyticus. The double dilution method was used to determine the bacteriostatic effects of three Chinese herbal medicines on V. alginolyticus. Results showed that P. mume has the highest antibacterial and bactericidal ability. The MIC and MBC of P. mume, C. pinnatifida, and C. chinensis on V. alginolyticus was 3.91 , 31.25 , and 125 mg/mL, respectively. Finally, MTT method was applied to evaluate the effects of C. pinnatifida, C. chinensis, and P. mume on the biofilm formation of V. alginolyticus, and results showed that the MIC on the biofilm formation of V. alginolyticus was 15.63 , 7.81,and 3.91 mg/mL, respectively; the MIC of P. mume was the lowest. [Conclusions] This experiment proves that P. mume, C. chinensis, and C. pinnatifida have inhibitory effects on V. alginolyticus and its biofilm formation. It is expected to provide references for prevention and control of pathogenic vibrio induced diseases of aquatic animals.

description: It is well known that although the group velocity of structured light pulses propagating in vacuum can be subluminal or superluminal, the upper limit of the energy flow velocity is c, the speed of light in vacuum. This inequality can be explained in terms of the reactive energy left behind by the fields. Energy and reactive energy densities have been calculated for vector-valued two-dimensional (light sheet) superluminal electromagnetic nondiffractive pulses, as well as scalar-valued and TM three-dimensional superluminal and subluminal spatiotemporally localized electromagnetic waves. Emphasis is placed on the physical formation of the reactive energy due to interference of the plane-wave constituents of the structured light waves.

description: With the greenhouse soil that had been planted with cucumber as the control, the greenhouse soil that had been planted with pepper for 3, 7, 10 and 15 consecutive years was collected, and the effects of continuous cropping on plant height, stem diameter, leaf area, yield, photosynthetic pigment content and fruit quality of pepper were investigated by pot experiment. The results showed that with the extension of continuous cropping duration, the plant height, stem diameter and yield of pepper decreased significantly compared with the control; and the mass fraction of photosynthetic pigments declined, and the mass fractions of chlorophyll a and total chlorophyll were significantly lower than those of the control. Under the condition of continuous cropping, the fruit quality of pepper decreased significantly, and the mass fractions of soluble solids and soluble protein were significantly lower than those of the control.

description: The COVID-19 pandemic and the measures taken to mitigate its spread have had a dramatic effect on the circulation patterns of other respiratory viruses, most especially influenza viruses. Since April 2020, the global circulation of influenza has been markedly reduced; however, it is still present in a number of different countries and could pose a renewed threat in the upcoming Northern Hemisphere winter. Influenza vaccination remains the most effective preventive measure that we have at our disposal against influenza infections and should not be ignored for the 2021-2022 season.
title: A Bayesian dynamic approach to modelling flow through a traffic network.
Creators: name: Wright, Benjamin John
Publisher: name: The Open University
Year: 2006

description: Hourly traffic flows through complicated motorway junctions form time series with a hierarchical element. Multiregression Dynamic Models provide a Bayesian framework for forecasting the time series while incorporating this hierarchical structure. Calculation of forecasts is computationally inexpensive and the model is designed in order to have readily interpretable parameters wherever possible. Expert intervention is straightforward in this system for periods of unusual activity, whether they were anticipated or not. Fundamental change to the road layout and behaviour can also be incorporated into the model without untenable complication. In this thesis work is centred on applying the methodology to one particular junction, including finding techniques to aid in using the methodology in this application. The theory of Multiregression Dynamic Models is furthered in order to do this- specifically through modelling certain parameter constraints imposed by the nature of the problem and the production of prior covariances for quantities modelled. The model was found to perform competitively in comparison to common other approaches, and the hierarchical structure offered significant advantages when expert intervention was applied.

description: Amorphous, glass, and glass-ceramic materials practically always include a significant number (more than eight) of crystalline phases, with the contents of the latter ranging from a few wt.% to several hundredths or tenths of wt.%. The study of such materials using the method of X-ray phase analysis faces difficulties, when determining the phase structure. In this work, we will develop a method for the analysis of the diffraction patterns of such materials, when diffraction patterns include X-ray lines, whose intensities are at the noise level. The identification of lines is based on the search for correlations between the experimental and test lines and the verification of the coincidence making use of statistical methods (computer statistics). The method is tested on the specimens of a-quartz, which are often used as standard ones, and applied to analyze lava-like fuel-containing materials from the destroyed Chornobyl NPP Unit 4. It is shown that the developed technique allows X-ray lines to be identified, if the contents of separate phases is not less than 0.1 wt.%. The method also significantly enhances a capability to determine the phase contents quantitatively on the basis of lines with low intensities.

description: We focus on a metallic quantum dot coupled to a reservoir of electrons through a single-mode quantum point contact and capacitively connected to a back-gate, by taking into account that the gate voltage can exhibit noise; This will occur when connecting the gate lead to an external transmission line with a finite Ohmic resistance. The voltage (charge) fluctuations at the back gate can be described through a Caldeira-Leggett model of harmonic oscillators. For weak tunneling between the lead qnd the dot, exploiting the anisotropic Bose-Fermi Kondo model, we show that zero-point fluctuations of the environment can markedly alter the previous Matveev Kondo fixed point leading to an amplification of the Coulomb blockade phenomenon.

description: The Tycho supernova remnant (SNR), as one of the few historical SNRs, has been widely studied in various wavebands. Observations show evidence that Tycho is expanding in a medium with density gradient and possibly interacting with dense ambient medium toward the northeast direction. From the FCRAO CO survey of the outer Galaxy, we have identified a patch of molecular clouds in this area and have conducted a follow-up observation with Nobeyama 45m radio telescope. The high-resolution (16\arcsec) Nobeyama data shows that a large molecular cloud surrounds the SNR along the northeastern boundary. We suggest that the Tycho SNR and the molecular cloud are located in the Perseus arm and that the dense medium interacting with the SNR is possibly the molecular cloud. We also discuss the possible connection between the molecular cloud and the Balmer-dominated optical filaments, and suggest that the preshock gas may be accelerated within the cosmic ray and/or fast neutral precursor.

description: Correlation analysis and principal component analysis (PCA) were conducted for some agronomic traits of 139 recombinant inbred lines of Brassica juncea L. The results showed that under the environmental conditions in Guiyang, the flowering time, number of seeds per silique, plant height and thousand seed weight differed significantly among different lines. The results of principal component analysis showed that the lines could be classified into three groups. The results of Pearson correlation tests showed that the plant height was positively correlated with the flowering time (P<0.05), and the thousand seed weight was negatively correlated with the flowering time and number of seeds per silique (P<0.01).

description: The influence of gluon and Goldstone boson induced tensor interactions on the dibaryon masses and D-wave decay widths has been studied in the quark delocalization, color screening model. The effective S-D wave transition interactions induced by gluon and Goldstone boson exchanges decrease rapidly with increasing strangeness of the channel. The tensor contribution of K and $η$ mesons is negligible in this model. There is no six-quark state in the light flavor world studied so far that can become bound by means of these tensor interactions besides the deuteron. The partial D-wave decay widths of the $IJ^p={1/2}2^+$ N$Ω$ state to spin 0 and 1 $ΛΞ$ final states are 12.0 keV and 21.9 keV respectively. This is a very narrow dibaryon resonance that might be detectable in relativistic heavy ion reactions by existing RHIC detectors through the reconstruction of the vertex mass of the decay product $ΛΞ$ and by the COMPAS detector at CERN or at JHF in Japan and the FAIR project in Germany in the future.

description: Based on the general survey of crop germplasm resources in Hubei Province, the third survey and collection of crop germplasm resources was conducted in 199 villages of 19 counties (cities/districts) of Hubei Province during 2015-2017. A total of 1 072 accessions of vegetables were collected. The taxonomy, distribution, agronomic traits and preservation of the vegetable germplasm resources, as well as the main vegetable resources and characteristic resources in the 19 counties (cities/districts) were analyzed. The results showed that the local vegetable landraces cover 26 families. Hong'an County, Zhongxiang City, Gucheng County, Nanzhang County and Yuan'an County have more vegetable landraces than other counties (cities/districts). The local landraces are characterized by good quality, strong resistance and tolerance to barrenness, but most of them are distributed in remote areas with low purity, low yield and serious threat of degradation. The local vegetable landraces are mostly preserved by some well-educated elder farmers. The vegetable cultivars of Cruciferae, Solanaceae, Cucurbitaceae, Liliaceae and Leguminosae account for 71.46% of the total vegetable resources. The characteristic vegetable resources such as pearl flower (Staghylea bumalda DC.), scallion (Allium paepalanthoides) and elephant-foot yam (Amorphophallus spp.) are scattered in the mountainous areas of Hubei Province. This study can provide reference for the protection and utilization of local resources of vegetables in Hubei Province.

description: Abstract: Background: Pandemic COVID-19 caused by the coronavirus SARS-CoV-2 has a high incidence of patients with severe acute respiratory syndrome (SARS). Many of these patients require admission to an intensive care unit (ICU) for invasive ventilation and are at significant risk of developing a secondary, ventilator-associated pneumonia (VAP). Objectives: To study the incidence of VAP and bacterial lung microbiome composition of ventilated COVID-19 and non-COVID-19 patients. Methods: In this retrospective observational study, we compared the incidence of VAP and secondary infections using a combination of microbial culture and a TaqMan multi-pathogen array. In addition, we determined the lung microbiome composition using 16S RNA analysis in a subset of samples. The study involved 81 COVID-19 and 144 non-COVID-19 patients receiving invasive ventilation in a single University teaching hospital between March 15th 2020 and August 30th 2020. Results: COVID-19 patients were significantly more likely to develop VAP than patients without COVID (Cox proportional hazard ratio 2.01 95% CI 1.14–3.54, p = 0.0015) with an incidence density of 28/1000 ventilator days versus 13/1000 for patients without COVID (p = 0.009). Although the distribution of organisms causing VAP was similar between the two groups, and the pulmonary microbiome was similar, we identified 3 cases of invasive aspergillosis amongst the patients with COVID-19 but none in the non-COVID-19 cohort. Herpesvirade activation was also numerically more frequent amongst patients with COVID-19. Conclusion: COVID-19 is associated with an increased risk of VAP, which is not fully explained by the prolonged duration of ventilation. The pulmonary dysbiosis caused by COVID-19, and the causative organisms of secondary pneumonia observed are similar to that seen in critically ill patients ventilated for other reasons.

description: Simultaneous processing of multiple video sources requires each pixel in a frame from a video source to be processed synchronously with the pixels at the same spatial positions in corresponding frames from the other video sources. However, simultaneous processing is challenging as corresponding frames from different video signals provided by multiple sources have time-varying delay because of the electrical and mechanical restrictions inside the video sources hardware that cause deviation in the corresponding frame rates. Researchers overcome the aforementioned challenges either by utilizing ready-made video processing systems or designing and implementing a custom system tailored to their specific application. These video processing systems lack flexibility in handling different applications requirements such as the required number of video sources and outputs, video standards, or frame rates of the input/output videos. In this paper, we present a design for a flexible simultaneous video processing architecture that is suitable for various applications. The proposed architecture is upgradeable to deal with multiple video standards, scalable to process/produce a variable number of input/output videos, and compatible with most video processors. Moreover, we present in details the analog/digital mixed-signals and power distribution considerations used in designing the proposed architecture. As a case study application of the proposed flexible architecture, we utilized the architecture for a realization of a simultaneous video processing system that performs video fusion from visible and near-infrared video sources in real time. We make available the source files of the hardware design along with the bill of material (BOM) of the case study to be a reference for researchers who intend to design and implement simultaneous multi-video processing systems.

description: Abstract: Sequencing studies of diffuse large B cell lymphoma (DLBCL) have identified hundreds of recurrently altered genes. However, it remains largely unknown whether and how these mutations may contribute to lymphomagenesis, either individually or in combination. Existing strategies to address this problem predominantly utilize cell lines, which are limited by their initial characteristics and subsequent adaptions to prolonged in vitro culture. Here, we describe a co-culture system that enables the ex vivo expansion and viral transduction of primary human germinal center B cells. Incorporation of CRISPR/Cas9 technology enables high-throughput functional interrogation of genes recurrently mutated in DLBCL. Using a backbone of BCL2 with either BCL6 or MYC, we identify co-operating genetic alterations that promote growth or even full transformation into synthetically engineered DLBCL models. The resulting tumors can be expanded and sequentially transplanted in vivo, providing a scalable platform to test putative cancer genes and to create mutation-directed, bespoke lymphoma models.

description: Abstract: Magnetic skyrmions are topologically nontrivial particles with a potential application as information elements in future spintronic device architectures. While they are commonly portrayed as two dimensional objects, in reality magnetic skyrmions are thought to exist as elongated, tube-like objects extending through the thickness of the host material. The study of this skyrmion tube state (SkT) is vital for furthering the understanding of skyrmion formation and dynamics for future applications. However, direct experimental imaging of skyrmion tubes has yet to be reported. Here, we demonstrate the real-space observation of skyrmion tubes in a lamella of FeGe using resonant magnetic x-ray imaging and comparative micromagnetic simulations, confirming their extended structure. The formation of these structures at the edge of the sample highlights the importance of confinement and edge effects in the stabilisation of the SkT state, opening the door to further investigation into this unexplored dimension of the skyrmion spin texture.

Level statistics of XXZ spin chains with a random magnetic field

description: The level-spacing distribution of a spin 1/2 XXZ chain is numerically studied under random magnetic field. We show explicitly how the level statistics depends on the lattice size L, the anisotropy parameter $Δ$, and the mean amplitude of the random magnetic field h. In the energy spectrum, quantum integrability competes with nonintegrability derived from the randomness, where the XXZ interaction is modified by the parameter $Δ$. When $Δ\ne 0$, the level-spacing distribution mostly shows Wigner-like behavior, while when $Δ$=0, Poisson-like behavior appears although the system is nonintegrable due to randomness. Poisson-like behavior also appears for $Δ\ne 0$ in the large h limit. Furthermore, the level-spacing distribution depends on the lattice size L, particularly when the random field is weak.

description: Sure screening technique has been considered as a powerful tool to handle the ultrahigh dimensional variable selection problems, where the dimensionality p and the sample size n can satisfy the NP dimensionality log p=O(n^a) for some a>0 (Fan & Lv 2008). The current paper aims to simultaneously tackle the "universality" and "effectiveness" of sure screening procedures. For the "universality", we develop a general and unified framework for nonparametric screening methods from a loss function perspective. Consider a loss function to measure the divergence of the response variable and the underlying nonparametric function of covariates. We newly propose a class of loss functions called conditional strictly convex loss, which contains, but is not limited to, negative log likelihood loss from one-parameter exponential families, exponential loss for binary classification and quantile regression loss. The sure screening property and model selection size control will be established within this class of loss functions. For the ``effectiveness", we focus on a goodness of fit nonparametric screening (Goffins) method under conditional strictly convex loss. Interestingly, we can achieve a better convergence probability of containing the true model compared with related literature. The superior performance of our proposed method has been further demonstrated by extensive simulation studies and some real scientific data example.

description: High-energy (h$ν$ = 5.95 keV) synchrotron Photoemission spectroscopy (PES) is used to study bulk electronic structure of Na$_{0.35}$CoO$_{2}$.1.3H$_{2}$O, the layered superconductor. In contrast to 3-dimensional doped Co oxides, Co $\it{2p}$ core level spectra show well-separated Co$^{3+}$ and Co$^{4+}$ ions. Cluster calculations suggest low spin Co$^{3+}$ and Co$^{4+}$ character, and a moderate on-site Coulomb correlation energy U$_{dd}\sim$3-5.5 eV. Photon dependent valence band PES identifies Co $\it{3d}$ and O $\it{2p}$ derived states, in near agreement with band structure calculations.
