In plant breeding,unmanned aerial vehicles(UAVs)carrying multispectral cameras have demonstrated increasing utility for high-throughput phenotyping(HTP)to aid the interpretation of genotype and environment effects on morphological,biochemical,and physiological traits.A key constraint remains the reduced resolution and quality extracted from“stitched”mosaics generated from UAV missions across large *** can be addressed by generating high-quality reflectance data from a single nadir image per *** this study,a pipeline was developed to derive reflectance data from raw multispectral UAV images that preserve the original high spatial and spectral resolutions and to use these for phenotyping *** steps involved(i)imagery calibration,(ii)spectral band alignment,(iii)backward calculation,(iv)plot segmentation,and(v)*** step was designed and optimised to estimate the number of plants and count sorghum heads within each breeding *** a derived nadir image of each plot,the coefficients of determination were 0.90 and 0.86 for estimates of the number of sorghum plants and heads,***,the reflectance information acquired from the different spectral bands showed appreciably high discriminative ability for sorghum head colours(i.e.,red and white).Deployment of this pipeline allowed accurate segmentation of crop organs at the canopy level across many diverse field plots with minimal training needed from machine learning approaches.

用牛顿力学分析舞蹈运动可以深入了解美学的表演,不仅对学生和教师,而且对舞蹈观众也是有价值的。大多数的舞蹈爱好者-舞蹈演员、教师和观众-认为舞蹈是一种有音乐伴奏的人体运动的纯粹美学表演艺术。他们承认对舞蹈演员的要求是传播舞蹈动作设计师和舞蹈演员设想的看得见的象。很多人也认识到舞蹈欣赏的问题依赖于认识表演好这些运动的困难-使物理上复杂的步子显得平滑而庄重。然而,为了理解表演者

A great deal of has been written about the challenges of a legal profession that resists change and sub-optimizes clients’benefits,and even more ink has been spilled on the opportunities and threats of *** laws are falling further behind an accelerating,dynamic world,the gap between businesses and opaque legal functions widens with the latter being perceived often as fire-fighting cost *** article calls out the opportunity of AI,specifically machine learning,and its impact on decision making as an opportunity for business leaders to elevate lawyers to contribute further to corporate strategies and *** the implications of machine learning through the lens of each element of decision making,the article aims to bring the relevance of today’s ubiquitous transformations to the legal *** also reminds business leaders that the legal function will need some help,such as corporate legal strategists,to drive and sustain change that resides in the intersection of law,business and technology.

Well-Posedness of Stochastic Continuity Equations on Riemannian Manifolds

Chinese Annals of Mathematics,Series B 2024年第1期45卷 81-122页

作者： Luca GALIMBERTI kenneth H.KARLSEN Department of Mathematical Sciences NTNU Norwegian University of Science and TechnologyN-7491 TrondheimNorway Department of mathematics University of OsloP.O.Box 1053BlindernN-0316 OsloNorway

The authors analyze continuity equations with Stratonovich stochasticity,■ρ+divh[ρo(u(t,x)+∑_(i=1)^(N)a_(i)(x)w_(i)(t))]=0defined on a smooth closed Riemannian manifold M with metric *** velocity field u is perturbed by Gaussian noise terms Wi(t),:WN(t)driven by smooth spatially dependent vector fields a1(x),...,aN(x)on *** velocity u belongs to L_(t)^(1)W_(x)^(1,2)with divh u bounded in Lf,for p>d+2,where d is the dimension of M(they do not assume div_(h) u∈L_(t,x)^(∞)).For carefully chosen noise vector fields ai(and the number N of them),they show that the initial-value problem is well-posed in the class of weak L^(2) solutions,although the problem can be ill-posed in the deterministic case because of concentration *** proof of this“regularization by noise”result is based on a L^(2) estimate,which is obtained by a duality method,and a weak compactness argument.

我国现行法律解释对于正确实施法律和弥补立法粗疏等方面起到了积极作用,但是由于复杂的历史和现实原因,现行法律解释在制度和观念等方面均与法治存在冲突。这些冲突主要表现在法律解释的法律依据的规范性程度差;在法律解释主体方面存在立法解释和检察解释,行政解释权过大等。
