智能化家庭室内蔬菜种植系统- E BLOOMING

随着社会的不断进步,城市化程度越来越深,人们的生活远离了耕种,取而代之的是生活在现代的高楼大厦里。没有土地,大家只能吃到从市场上买来的蔬菜,但是这些蔬菜中有很多是被农药或者化学物质污染。为了健康,一部分人开始在阳台或者楼顶自己种植生态无公害蔬菜。本课题旨在设计一种未来的家庭种植及智能化物联网的生活方式,从而实现环保、智能、健康的生活理念。

Comparative transcriptome analysis identifies differentially expressed genes between normal and late-blooming Siberian apricot

Blooming date is an important trait in fruit tree species.Although several quantitative trait loci confirming blooming date were identified in Prunus spp.,the molecular mechanism underlying it remains unclear.Arising from this,the transcriptomes of normal blooming and lateblooming Siberian apricot(P.sibirica L.)flower buds were analyzed using RNA-seq technology.A total of 68,855 unigenes were de novo assembled,among which 1204 were differentially expressed between normal and late blooming.Gene ontology enrichment analysis revealed that biological processes were enriched with metabolic processes.The catalytic-related gene transcripts between the two types of blooming were significantly changed in the molecular function.Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that 156 genes were successfully annotated and 75 pathways enriched.Genes for gibberellin biosynthesis were up-regulated in normal blooming,whereas abscisic acid degradation-related genes were also up-regulated in normal blooming.Moreover,circadian rhythms related genes including EARLY FLOWERING 4,LATE ELONGATED HYPOCOTYL and CIRCANDIAN CLOCK ASSOCIATED1 were all up-regulated in normal blooming,indicating that circadian rhythms have a very important role in controlling blooming date.Furthermore,zinc finger protein CONSTANS-LIKE 12 was blasted onto the quantitative trait loci region on linkage group 4 in peach.However,changes in the abundance of key flowering genes such as SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1,FLOWERING LOCU T,LEAFY and FLOWERING LOCUS C were not significantly different,indicating that further investigation should explore the function of these genes on blooming date.The outcomes of this study will provide a valuable platform for further research on the molecular mechanism of blooming date in Prunus.

Theoretical and experimental studies on high-power laser-induced thermal blooming effect in chamber with different gases

High-power laser induced thermal blooming effects in a closed chamber with three different gases are investigated theoretically and experimentally in this work. In the theoretical treatment, an incompressible gas turbulent model is adopted.In the numerical simulation the gas refractive index as a function of both the temperature and pressure is taken into consideration. In the experimental study the pump-probe technology is adopted. A high-power 1064-nm fiber laser with maximum output power of 12 k W is used to drive the gas thermal blooming, and a 50-m W high-beam-quality 637-nm laser diode(LD)is used as a probe beam. The influences of the gas thermal blooming in the chamber on the probe beam wavefront and beam quality are analyzed for three different gases of air, nitrogen, and helium, respectively. The results indicate that nitrogen is well suitable for restraining thermal blooming effect for high-power laser. The measured data are in good agreement with the simulated results.

Cardiac CT blooming artifacts:clinical significance,root causes and potential solutions

This review paper aims to summarize cardiac CT blooming artifacts,how they present clinically and what their root causes and potential solutions are.A literature survey was performed covering any publications with a specific interest in calcium blooming and stent blooming in cardiac CT.The claims from literature are compared and interpreted,aiming at narrowing down the root causes and most promising solutions for blooming artifacts.More than 30 journal publications were identified with specific relevance to blooming artifacts.The main reported causes of blooming artifacts are the partial volume effect,motion artifacts and beam hardening.The proposed solutions are classified as high-resolution CT hardware,high-resolution CT reconstruction,subtraction techniques and post-processing techniques,with a special emphasis on deep learning(DL)techniques.The partial volume effect is the leading cause of blooming artifacts.The partial volume effect can be minimized by increasing the CT spatial resolution through higherresolution CT hardware or advanced high-resolution CT reconstruction.In addition,DL techniques have shown great promise to correct for blooming artifacts.A combination of these techniques could avoid repeat scans for subtraction techniques.

英语句型的拓展方式及其练习活动设计

英语有系统的句型结构,主要包含简单句、复杂句和复合句三种句型。每种句型都遵循一定的句型拓展规律和思维模式。简单句的组建主要依赖动词完成,动词组建信息的多少常决定简单句的复杂程度。复杂句的产生源自简单句句子成分的复杂化和对词汇或主句等修饰限定成分的增加。复合句常由多个独立语句按照逻辑关系组建而成。清晰了解英语句型的拓展方式有助于教师改进句型教学方法。同时,在教学中,按照Bloom的教育目标分类,遵循从易到难的学习认知规律,设计各种句型拓展练习和活动,引导学生从记忆、理解应用、分析创造、评价层面训练掌握句型。

Inheritance of Perpetual Blooming in Rosa chinensis ‘Old Blush'

Perpetual blooming is one of the most important biological and economical traits in modern rose, while the genetic basis underlining the control of this trait is poorly investigated. With an aim in dissecting the genetic determinism of perpetual blooming, we developed six rose populations(OB, W, F1, F2, BC1 OB and BC1W) derived from a WOB population [interspecific diploid hybridization between Rosa chinensis ‘Old Blush'(OB) and R. wichuriana ‘Basye's Thornless'(W)]. Perpetual blooming is absent both in a F1 population with 296 individuals and a BC1 W population(W as the backcross parent) with 150 individuals. However, the perpetual blooming trait showed a typical 3︰1 segregation in a backcross population BC1 OB with OB as the backcross parent. In this population with 300 individuals, 83 plants had the perpetual blooming phenotype while the other 217 featured non-perpetual blooming, indicating that the perpetual blooming trait is very likely controlled by two recessive genes in R. chinensis(rpb1 and rpb2). These genetic data suggest that the inheritance of rose perpetual blooming may be controlled by a complex mechanism.

A verifiable essential secret image sharing scheme based on HLRs(VESIS-(t,s,k,n))

In traditional secret image sharing schemes,a secret image is shared among shareholders who have the same position.But if the shareholders have two different positions,essential and non‐essential,it is necessary to use essential secret image sharing schemes.In this article,a verifiable essential secret image sharing scheme based on HLRs is proposed.Shareholder's share consists of two parts.The first part is produced by the shareholders,which prevents the fraud of dealers.The second part is a shadow image that is produced by using HLRs and the first part of share.The verification of the first part of the shares is done for the first time by using multilinear and bilinear maps.Also,for verifying shadow images,Bloom Filters are used for the first time.The proposed scheme is more efficient than similar schemes,and for the first part of the shares,has formal security.

Lü Huanhu on “The Blooming Peach Flowers”

Appreciating a Chinese painting is a bit different from appreciating a Western painting.Chinese paintings are not overly realistic.For example,light,shadow and perspective are not stressed.One needs knowledge of Chinese culture to understand the lingering charm and subtle nuances.This painting depicts peach flowers on the shores of a river in spring.My inspiration originated from'The Tale of the Peach Blossom Spring'

Paper-cuts Like Red Flowers Blooming in the Snow

IN those days, when heavy snow sealed the mountain passes, it was only the sight of red paper-cuts on the windows which said to me there were people living in those houses covered with deep and solid snow. Every time I travel to the Northwest, I have come across paper-cutters who touch me so deeply that I can’t forget their faces even long after I return to the city. Sometimes in the harsh winters of the Northwest, there is no color but the monotonous white of the snow until the lively red of the paper-cuts spring into sight. These colorful, waiting things like cheerful signals of warmth and humanity,

基于Bloom分类法的CS1试题数据集的构建及其自动分类

课程评估是教学改革的一个关键环节,涉及教学案例、试题以及课堂教学等方面的内容。针对计算课程的试题评估,引入Bloom分类法,以普林斯顿大学和桂林电子科技大学“计算机科学导论”课程(CS1)的试题为语料库,给出针对CS1的Bloom分类法认知过程维度和知识维度的相应动词种子库和名词种子库,对试题所能达到的Bloom分类法二维矩阵的位置进行标注,构建CS1试题分类数据集。采用机器学习技术,给出CS1试题自动分类模型TFERNIE-LR,该模型由CSTFPOS-IDF算法、ERNIE模型和LR分类器3部分组成。CSTFPOS-IDF算法是在TFPOS-IDF算法的基础上,通过计算课程关键词权重因子,来提高模型对计算课程关键词的关注程度,生成词权重。同时,基于实体知识增强预训练模型ERNIE进行试题词语级向量嵌入,组合词权重和词语级向量生成用于自动分类的试题文本向量。最后,采用LR分类器将试题自动分类到Bloom分类法二维矩阵。实验结果表明,TFERNIE-LR模型具有良好的性能,在认知过程维度和知识维度上的加权精确率分别达到了83.3%和96.1%。
