The way towards generating a website front end involves a designersettling on an idea for what kind of layout they want the website to have, thenproceeding to plan and implement each aspect one by one until they haveconverted what they initially laid out into its Html front end form, this processcan take a considerable time, especially considering the first draft of the designis traditionally never the final one. This process can take up a large amountof resource real estate, and as we have laid out in this paper, by using a Modelconsisting of various Neural Networks trained on a custom dataset. It can beautomated into assisting designers, allowing them to focus on the other morecomplicated parts of the system they are designing by quickly generating whatwould rather be straightforward busywork. Over the past 20 years, the boomin how much the internet is used and the sheer volume of pages on it demands ahigh level of work and time to create them. For the efficiency of the process, weproposed a multi-model-based architecture on image captioning, consisting ofConvolutional neural network (CNN) and Long short-term memory (LSTM)models. Our proposed approach trained on our custom-made database can beautomated into assisting designers, allowing them to focus on the other morecomplicated part of the system. We trained our model in several batches overa custom-made dataset consisting of over 6300 files and were finally able toachieve a Bilingual Evaluation Understudy (BLEU) score for a batch of 50hand-drawn images at 87.86%.

血吸虫病是一种严重的世界性寄生虫病。控制血吸虫病的最佳方法之一是控制钉螺种群。目前多采用化学杀螺剂如氯硝柳胺控制钉螺。化学杀螺虽然杀螺效果好,但对水生生物的毒性和环境的污染问题难以克服。因此,我们试图寻找一种高效、低毒的生物源灭螺剂,以期避免化学杀螺剂的负面作用。苦葛是一种传统中药,用于治疗酗酒、心脏病、糖尿病等疾病,但鲜见苦葛用于杀螺报道。本研究以苦葛根为材料,通过水提法和有机溶剂提取法提取皂甙,并用于检测杀螺剂活性。结果表明,有机溶剂如乙醇提取物杀螺效果好于水提物。乙醇提取物杀螺效果具有时间效应和浓度效应,即随着处理时间的延长和处理浓度的增加,杀螺效果增加。其48小时、72小时、96小时的半数致死率LC分别为0.943mg/L、0.671mg/L和0.526mg/L,致死率LC分别为2.251mg/L、1.816mg/L和1.601mg/L,表现出较强的杀螺作用。用1/4LC、1/2LC和LC浓度乙醇提取物处理钉螺,测定钉螺肝脏生理指标,如总蛋白、肝糖原以及肝功能生理指标(酶谷氨酸-草酰乙酸转氨酶(GOT)和谷氨酸-丙酮酸转氨酶(GPT))。结果表明,钉螺肝脏总蛋白和肝糖原随处理时间延长和处理浓度增加,其含量显著低于对照,尤其肝糖原更甚。GOT和GPT含量总体呈先显著增趋势。表明苦葛提取物对钉螺能量代谢以及肝功能有明显损伤。通过高效液相色谱/质谱(HPLC-MS)进一步分析乙醇提取物,发现苦葛根提取物主要活性成分有皂苷A(20%)、B(19%)、C(14%)和D(24%)。总之,苦葛皂甙具有很强的杀螺作用,可作为潜在的植物源杀螺剂。其作用的毒理机制可能是皂甙导致钉螺能量耗竭,肝功能受损所致。

The basic objective of this work is to study the heat transfer of Casson fluid of non-Newtonian nature.The fluid is considered over a vertical plate such that the plate exhibits arbitrary wall shear stress at the boundary.Heat transfers due to exponential plate heating and natural convection are due to buoyancy force.Magnetohydrodynamic(MHD)analysis in the occurrence of a uniform magnetic field is also considered.The medium over the plate is porous and hence Darcy’s law is applied.The governing equations are established for the velocity and temperature fields by the usual Boussinesq approximation.The problem is first written in dimensionless form using some useful non-dimensional quantities and then solved.The exact analysis is performed and hence solutions via integral transform are established.The analysis of various pertinent parameters on temperature distribution and velocity field are reported graphically.It is found that pours medium permeability parameter retards the fluid motion whereas,velocity decreases with increasing magnetic parameter.Velocity and temperature decrease with increasing Prandtl number whereas the Grashof number enhances the fluid motion.Further,it is concluded from this study that the results obtained here are more general and in a limiting sense several other solutions can be recovered.The Newtonian fluid results can be easily established by taking the Casson parameter infinitely large i.e.,whenβ→∞.

Forest plays a vital role in the global biogeochemical cycles through a high rate of carbon sequestration and harboring biodiversity.However,local species diversity is declining while also becoming increasingly homogenized across communities.Although eff ects of local biotic processes(e.g.,speciesα-diversity and stand structural heterogeneity)and environmental factors on aboveground biomass(AGB)have been widely tested,there is a huge knowledge gap for the eff ect of regional biotic processes(i.e.,taxonomic and functionalβ-diversity)in forests.Here,we hypothesized that regional and local environmental factors along with biotic processes jointly regulate AGB through species shifts in tropical forests.Using piecewise structural equation modeling(pSEM),we linked climatic water availability,soil fertility,stand structural heterogeneity(either tree DBH inequality,height inequality,or stand density),speciesα-diversity,taxonomic or functionalβ-diversity(and its two components;β-turnover andβ-richness),and AGB across 189 inventory plots in tropical forests of Sri Lanka.Soil fertility and climatic water availability shaped local and regional biotic processes.Stand structural heterogeneity promoted speciesα-diversity but declinedβ-diversity(but increasedβ-taxonomic turnover).Speciesα-diversity and stand structural heterogeneity promoted AGB whereas taxonomic and functionalβ-diversity declined(butβ-taxonomic turnover increased)AGB.The relationships of AGB with speciesα-diversity andβ-diversity varied from signifi cant to nonsignifi cant positive depending on the specifi c combinations of stand structural heterogeneity metrics used.This study shows that local biotic processes could increase AGB due to the local and regional niche complementarity eff ect whereas the regional biotic processes could restrict AGB due to the regional selection or functional redundancy eff ect under favorable environmental conditions.We argue that biotic homogenization,as well as drought conditions,may have strong divergent impacts on forest functi

树木构型是木本植物为响应光照变化在其空间建造结构上的配置模式和形态体现。研究演替不同阶段共有种构型的变化可以剔除植物谱系的影响,反映植物构型特征与光资源供给性的关系。该研究在浙江宁波天童、南山和北仑3个次生演替序列上选择了5个演替共有种,分4个群落高度层级,对照分析了树高、冠幅深度和面积、枝条伸展方向、基径、叶片盖度和聚集度构型性状随演替的变化,并分析了与冠幅曝光指数的线性关系。结果表明:1)随着演替进行,冠幅厚度和面积、叶片盖度、叶片聚集度和基径逐步增加,但在个别相邻演替阶段增加不显著;2)随着演替进行,植物的垂直枝比例降低,水平枝比例增加;3)演替过程中植物冠幅曝光指数在各层级内都呈现出减小趋势;4)构型性状和植物冠幅曝光指数间存在显著的线性回归关系(p<0.001)。总之,随着常绿阔叶林演替进行,演替共有种构型的变化反映了物种功能类群由阳性先锋植物向耐阴植物的转化,其中,植物对光资源的适应是导致构型变化的主要原因。

回归模型可用于预测森林生态系统地上生物量,其中最为常用的是最小二乘回归模型。在预测灌木,尤其是多茎灌木的地上生物量时,最小二乘法与贝叶斯方法的比较很少被研究。我们开发了小叶锦鸡儿(Caragana microphylla Lam.)生物量预测模型。小叶锦鸡儿是科尔沁沙地广泛分布的多茎灌木,对减少风蚀、固定沙丘具有重要作用。本研究建立6种表征生物量的异速增长模型,并基于统计标准选择在预测生物量方面表现最佳的1种,然后分别用最小二乘法与贝叶斯方法对模型中的参数进行估计。参数估计过程中用自助法考察样本量大小的影响,同时区分测试集与训练集。最后,我们比较了最小二乘法与贝叶斯方法在小叶锦鸡儿地上生物量预测中的表现。异速增长的6个模型均达到显著水平,其中幂指数为1的模型表现最佳。研究结果表明,采用无先验信息与有先验信息的贝叶斯方法进行估计,得到的均方误差在测试集上低于最小二乘法。另外,基径作为预测变量在最小二乘法与贝叶斯方法中均不显著,表明在生物量预测模型中应谨慎选择合适变量。本研究强调贝叶斯方法、自助法和异速增长模型相结合能够提升沙地灌木生物量预测模型的准确度。

近年来,随着人们生活水平的提高和环保要求的提高,对天然可生物降解和环保纤维的需求在世界范围内不断增加。在诸多天然纤维中,黄麻是一种环保纤维,在诸多家庭作坊和工业生产中具有较大的应用潜力。黄麻纤维的低密度、低成本、可用性和良好的机械性能促使研究人员认为,在许多应用领域,尤其是在纺织复合材料领域,黄麻纤维是一种有前途的替代纤维。其在纤维增强聚合物复合材料（FRPC）中的应用日益广泛。FRPC由聚合物（热塑性塑料或热固性塑料）作为基体,纤维（合成纤维或天然纤维）作为增强材料。在FRPC中,纤维沿其纵向承受载荷,而增强纤维之间的应力则由聚合物基体传递。为了获得最佳的性能,必须形成牢固的基体与纤维的结合。另一方面,复合材料中天然纤维的主要不便之处在于纤维和基质之间的稠度差,以及高吸湿性。因此,在改变纤维表面特性时,应考虑采用碱性或冲刷处理,这也是常规纤维最常用的化学处理,同时用于增强热固性塑料和热塑性塑料。碱性或冲刷处理的本质变化是系统结构中氢键的中断,这种方式扩大了表面不匀度,以便更好地与基体结合。在其上面,处理扩大了在纤维表面发现的纤维素的测量,因此扩大了可想象的反应位点的数量。因此,在这项工作中,首先对黄麻纤维进行化学处理（酸预处理、碱处理或冲刷处理）。采用单向黄麻纤维组织制备了黄麻纤维/环氧树脂复合材料。考虑了复合材料的基本性能,如断裂延伸率、空隙率、初始模量、拉伸强度等。分析了经处理和未经处理或未经处理的黄麻纤维的扫描电子显微镜（SEM）图像和原子转移傅立叶变换红外光谱（ATR-FTIR）,以研究化学改性对纤维的影响。结果表明,化学处理或水洗处理对黄麻纤维复合材料的力学性能有显著影响,同时对复合材料中孔隙的排列也有显著影响。

Remote ischaemic conditioning for stroke: unanswered questions and future directions

Stroke & Vascular Neurology 2021年第2期6卷 298-309页

作者： Sheharyar Baig Bethany Moyle Krishnan Padmakumari Sivaraman Nair Jessica Redgrave arshad Majid ali ali Cerebrovascular Medicine The University of Sheffield Institute for Translational NeuroscienceSheffieldUK Neurosciences Sheffield Teaching Hospitals NHS Foundation TrustSheffieldUK Faculty of Medicine and Dentistry University of SheffieldSheffieldUK Geriatrics and Stroke Medicine Sheffield Teaching Hospitals NHS Foundation TrustSheffieldUK Sheffield NIHR Biomedical Research Centre The University of SheffieldSheffieldUK

Remote ischaemic conditioning(RIC)refers to a process whereby periods of intermittent ischaemia,typically via the cyclical application of a blood pressure cuff to a limb at above systolic pressure,confers systemic protection against ischaemia in spatially distinct vascular territories.The mechanisms underlying this have not been characterised fully but have been shown to involve neural,hormonal and systemic inflammatory signalling cascades.Preclinical and early clinical studies have been promising and suggest beneficial effects of RIC in acute ischaemic stroke,symptomatic intracranial stenosis and vascular cognitive impairment.Through systematic searches of several clinical trials databases we identified 48 active clinical trials of RIC in ischaemic stroke,intracerebral haemorrhage and subarachnoid haemorrhage.We summarise the different RIC protocols and outcome measures studied in ongoing clinical trials and highlight which studies are most likely to elucidate the underlying biological mechanisms of RIC and characterise its efficacy in the near future.We discuss the uncertainties of RIC including the optimal frequency and duration of therapy,target patient groups,cost-effectiveness,the confounding impact of medications and the absence of a clinically meaningful biomarker of the conditioning response.With several large clinical trials of RIC expected to report their outcomes within the next 2 years,this review aims to highlight the most important studies and unanswered questions that will need to be addressed before this potentially widely accessible and low-cost intervention can be used in clinical practice.

Deep Bimodal Fusion Approach for Apparent Personality Analysis

引用

Computers, Materials & Continua 2023年第4期75卷 2301-2312页

Personality distinguishes individuals’ patterns of feeling, thinking,and behaving. Predicting personality from small video series is an excitingresearch area in computer vision. The majority of the existing research concludespreliminary results to get immense knowledge from visual and Audio(sound) modality. To overcome the deficiency, we proposed the Deep BimodalFusion (DBF) approach to predict five traits of personality-agreeableness,extraversion, openness, conscientiousness and neuroticism. In the proposedframework, regarding visual modality, the modified convolution neural networks(CNN), more specifically Descriptor Aggregator Model (DAN) areused to attain significant visual modality. The proposed model extracts audiorepresentations for greater efficiency to construct the long short-termmemory(LSTM) for the audio modality. Moreover, employing modality-based neuralnetworks allows this framework to independently determine the traits beforecombining them with weighted fusion to achieve a conclusive prediction of thegiven traits. The proposed approach attains the optimal mean accuracy score,which is 0.9183. It is achieved based on the average of five personality traitsand is thus better than previously proposed frameworks.
