Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：SOME PROPERTIES OF STATIONARY CONTINUOUS STATE BRANCHING PROCESSES
稳态 连续状态 分支过程 性质
2023/4/14
We consider the genealogical tree of a stationary continuous state branching process with immigration. For a sub-critical stable branching mechanism, we consider the genealogical tree of the extant po...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Branching random walks driven by products of random matrices
随机矩阵 乘积驱动 分支随机 游走
2023/4/18
A branching random walk is a system of particles, where each particle gives birth to new particles of the next generation, which move on $\mathbb R^d$ according to some probability law. In this talk, ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Multitype branching processes in random environments
随机环境 多类型 分支进程
2023/4/18
We consider a branching process with a random environment, in which the reproduction law of generation $n$ depends on the random environment at time n, unlike a constant distribution assumed in the cl...
Transcriptome sequencing of active buds from Populus deltoides CL. and Populus×zhaiguanheibaiyang reveals phytohormones involved in branching
Transcriptome sequencing Populus deltoides CL. Populus×zhaiguanheibaiyang
2023/6/5
Branching in woody plants affects their ecological benefits and impacts wood formation. To obtain genome-wide insights into the transcriptome changes and regulatory mechanisms associated with branchin...
Effects of inhibiting starch branching enzymes on molecular and crystalline structures of starches from endosperm different regions in rice
Crystalline structure Endosperm regional tissue Molecular structure Rice Starch Starch branching enzyme
2023/8/9
Mature endosperm was separated regionally into different parts in three rice cultivars, Te-qing (TQ), Wu-xiang 9915 (WX9915) and Guang-ling-xiang-nuo (GLXN), and their transgenic lines with inhibition...
Cooking, morphological, mechanical and digestion properties of cooked rice with suppression of starch branching enzymes
Cooked rice In situ gelatinization Pasting properties Rheological properties Starch branching enzyme Textural properties
2023/8/9
Kernel components and some physicochemical properties of cooked rice were investigated and compared between a popular japonica rice Wu-xiang 9915 (WX) and its transgenic line (WX-SBEI/IIb-) with suppr...
Efficient Attribute-Based Signatures for Unbounded Arithmetic Branching Programs
attribute-based signatures arithmetic branching programs arithmetic span programs
2019/4/10
This paper presents the first attribute-based signature (ABS) scheme in which the correspondence between signers and signatures is captured in an arithmetic model of computation. Specifically, we desi...
Cryptanalyses of Branching Program Obfuscations over GGH13 Multilinear Map from NTRU Attack
Obfuscation multilinear maps graded encoding schemes
2018/5/11
In this paper, we propose cryptanalyses of all existing indistinguishability obfuscation (iO) candidates based on branching programs (BP) over GGH13 multilinear map. To achieve this, we introduce two ...

Terrestrial LiDAR L-system Branching structure Point cloud data Topology structure
2018/5/14
For the purpose of extracting productions of some specific branching plants effectively and realizing its 3D reconstruction, Terrestrial LiDAR data was used as extraction source of production, and a 3...
GGH15 Beyond Permutation Branching Programs: Proofs, Attacks, and Candidates
Graded encodings indistinguishability obfuscation
2018/4/19
We present new constructions of private constrained PRFs and lockable obfuscation, for constraints (resp. functions to be obfuscated) that are computable by general branching programs. Our constructio...

2016/6/17
Secure multilinear maps (mmaps) have been shown to have remarkable applications in cryptography, such as program obfuscation and multi-input functional encryption (MIFE). To date, there has been littl...
The paper develops a theory of branching spatiotemporal histories that accommodates indeterminism and the insights of general relativity. A model of this theory can be viewed as a collection of overla...
