Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Stability conditions and quadratic differentials
稳定性条件 二次微分 三角分类
2023/5/6
Stability conditions on triangulated categories are introduced by Bridgeland. For 3-Calabi-Yau triangulated categories from quivers with potentials, the space of stability conditions on this triangula...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Meromorphic differentials and Teichmüller space
亚纯微分 泰希米勒空间 全纯二次微分
2023/4/17
In the late 1980s, Nigel Hitchin and Michael Wolf independently discovered a parametrization of the Teichmüller space of a compact surface by holomorphic quadratic differentials. In this talk, I will ...
New Rigorous Analysis of Truncated Differentials for 5-round AES
AES Truncated-Differential Cryptanalysis Distinguisher/Attack
2018/3/6
Since the development of cryptanalysis of AES and AES-like constructions in the late 1990s, the set of inputs (or a subset of it) which differ only in one diagonal has special importance. It appears i...
Improvements for Finding Impossible Differentials of Block Cipher Structures
block cipher cryptanalysis impossible differential
2017/12/19
In this paper we improve Wu and Wang's method for finding impossible differentials of block cipher structures. This improvement is more general than Wu and Wang's method that it can find more impossib...
From Higher-Order Differentials to Polytopic Cryptanalysis
crytpanalysis block ciphers higher-order
2017/3/27
Polytopic cryptanalysis was introduced at EUROCRYPT 2016 as a cryptanalytic technique for low-data-complexity attacks on block ciphers. In this paper, we give an account of how the technique was devel...
Significantly Improved Multi-bit Differentials for Reduced Round Salsa and ChaCha
Stream Cipher ChaCha Salsa
2016/12/7
ChaCha and Salsa are two software oriented stream ciphers that have attracted serious attention in academic as well as commercial domain. The most important cryptanalysis of reduced versions of these ...
New Automatic Search Tool for Impossible Differentials and Zero-Correlation Linear Approximations
Automatic search tool impossible differential zero-correlation linear
2016/7/13
Impossible differential cryptanalysis and zero-correlation linear cryptanalysis are two of the most useful cryptanalysis methods in the field of symmetric ciphers. Until now, there are several automat...
Are Educational Differentials In Mortality Increasing in the United States?
Educational Differentials Mortality Increasing the United States
2016/3/18
Because of the value that i ndividuals place on health and longevity, levels of mortality are among the most central indicators of social and economic well-being. Analysts are concerned not only with ...
Sex Mortality Differentials in the United States:The Role of Cohort Smoking Patterns
Sex differentials Mortality Cigarette smoking
2016/3/18
This paper demonstrates that, over the period 1948-2003, sex differentials in mortality in the age range 50-54 to 85+ widened and then narrowed on a cohort rather than on a period basis. The cohort wi...
Growing Educational Differentials in the Retreat from Marriage among Korean Men
Marriage Korea Educational Differentials Gender 2010 Korean Census
2016/3/17
Applying discrete-time hazard models to person-year data constructed from 1% microdata sample of 2010
Korean Census, we explore how men’s education affects their transition to first marriage, and how...
Low Probability Differentials and the Cryptanalysis of Full-Round CLEFIA-128
CLEFIA cryptanalysis weak keys
2016/1/26
So far, low probability differentials for the key schedule of block ciphers have been used as a straightforward proof of security against related-key differential attacks. To achieve the resistance, i...
Analysis of ARX Functions: Pseudo-linear Methods for Approximation, Differentials, and Evaluating Diffusion
ARX block ciphers hash functions
2016/1/6
This paper explores the approximation of addition mod 2n
by addition mod 2w, where
1 ≤ w ≤ n, in ARX functions that use large words (e.g., 32-bit words or 64-bit words). Three main areas
are explor...
This paper proposes a method of valuing air quality based on differences in
wages among cities. Using an urban location model it is shown that the supply of
labor to any city increases with the real...
EXPONENTIAL THURSTON MAPS AND LIMITS OF QUADRATIC DIFFERENTIALS
Quadratic differential decomposition limit model iteration exponential map classification
2015/8/26
In the theory of iterated rational maps, the easiest maps to understand are postcritically finite: maps whose critical orbits are all periodic or preperiodic. These maps are also the most important ma...
Determinants of urban-rural differentials of antenatal care utilization in Nigeria
Urban-rural differentials antenatal care utilization
2015/7/27
Demographic and public health studies have indicated urban-rural differences in the utilization of antenatal care services. However, factors accounting for the urban-rural differentials in Antenatal C...
