As a car travels along a narrow city street, reflections off the glossy paint or side mirrors of parked vehicles can help the driver glimpse things that would otherwise be hidden from view, like a chi...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Rational points and homogeneous spaces over function fields of curves
曲线函数场 有理点 齐次空间
2023/4/17
In the last decade, there has been a growing interest in the study of rational points on homogeneous spaces of linear algebraic groups defined over fields having good arithmetical properties other tha...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Number of rational points of difference varieties in finite difference fields
有限差分域 差分簇 有理点数
2023/4/13
A difference field is a field with a distinguished automorphism. Automorphisms of a finite field are powers of the Frobenius map. In this talk, I will discuss how to estimate the number of rational po...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Birkhoff genericity for points on curves in expanding horospheres and Diophantine applications
星座图 曲线 Birkhoff泛型 丢番图应用
2023/5/16
Let $\{a(t):t \in \mathbb{R}\}$ be a diagonalizable subgroup of $SL(d,\mathbb{R})$ for which the expanded horosphere $U$ is abelian. By the Birkhoff ergodic theorem, for any point $x \in SL(d,\mathbb{...
Understanding past climate change 'tipping points' can help us prepare for the future
extreme climate change Earth system models hydrosphere

Of all the creatures on Earth, humans manipulate their environments the most. But, how far can we push it before something drastic happens? Scientists are calling for a better understanding of past ex...
Scientists last autumn revealed that the gas phosphine was found in trace amounts in Venus’ upper atmosphere. That discovery promised the slim possibility that phosphine serves as a biological signatu...
A Faster Constant-time Algorithm of CSIDH keeping Two Torsion Points
CSIDH post-quantum cryptography Isogeny-based cryptography
2019/4/3
At ASIACRYPT 2018, Castryck, Lange, Martindale, Panny and Renes proposed CSIDH, which is a key-exchange protocol based on isogenies between elliptic curves, and a candidate for post-quantum cryptograp...
We investigate the differential properties of a construction in which a given function F:F2n→F2nF:F2n→F2n is modified at K∈NK∈N points in order to obtain a new function GG. This is motivated by the qu...
STUDY ON CONTOROL POINTS LAYPUT BASED ON OBLIQUE PHOTOGRAPHY
Oblique Photography Layout of Control Points Density of Control Points Precision of Control Points
2018/5/15
In practical projects, suitable high-precision control points are often added in the adjustment calculation so as to accurately recover the relationships between different light beams at the time of p...
TIE POINTS EXTRACTION FOR SAR IMAGES BASED ON DIFFERENTIAL CONSTRAINTS
Synthetic Aperture Radar (SAR) Tie Points Matching Extraction Differential Constraints
2018/5/16
Automatically extracting tie points (TPs) on large-size synthetic aperture radar (SAR) images is still challenging because the efficiency and correct ratio of the image matching need to be improved. T...
EVALUATION OF PHOTOGRAMMETRIC BLOCK ORIENTATION USING QUALITY DESCRIPTORS FROM STATISTICALLY FILTERED TIE POINTS
Close range Photogrammetry Block orientation Tie points extraction Open source Data quality assessment
2018/6/4
Due to the increasing number of low-cost sensors, widely accessible on the market, and because of the supposed granted correctness of the semi-automatic workflow for 3D reconstruction, highly implemen...
THE EXAMINATION OF GATHERING POINTS’ CAPACITY REGARDING MOBILITY AND ACCESSIBILITY: CASE OF BAYRAKLI DISTRICT
