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...
On Kummer Lines With Full Rational 2-torsion and Their Usage in Cryptography
Montgomery curves Edwards curves Kummer lines
2018/11/16
A paper by Karati and Sarkar at Asiacrypt'17 has pointed out the potential for Kummer lines in genus one, by observing that its SIMD-friendly arithmetic is competitive with the status quo. A more rece...
Parameterization of Edwards curves on the rational field Q with given torsion subgroups
Edwards curve twisted Edwards curve torsion subgroups
2018/1/29
This paper presents the basic concepts of the Edwards curves, twisted Edwards curves and the point addition laws on these curves. The main result is the parameterization of the Edward curve with the g...
Faster Algorithms for Isogeny Problems using Torsion Point Images
isogeny-based cryptography cryptanalysis
2017/6/15
There is a recent trend in cryptography to construct protocols based on the hardness of computing isogenies between supersingular elliptic curves. Two prominent examples are Jao-De Feo's key exchange ...
Torsion Limits and Riemann-Roch Systems for Function Fields and Applications
Algebraic curves Jacobian torsion limit
2016/1/23
The Ihara limit (or constant) A(q) has been a central problem of study in the asymptotic theory of global function fields (or equivalently, algebraic curves over finite fields). It addresses global ...
Construction of Arithmetic Secret Sharing Schemes by Using Torsion Limits
Algebraic function fields torsion limits Riemann-Roch systems of equations
2015/12/29
Recent results of Cascudo, Cramer, and Xing on the construction of
arithmetic secret sharing schemes are improved by using some new bounds
on the torsion limits of algebraic function fields. Further...
Emphysematous lesions in the right cranial lung lobe and torsion of the right medial lung lobe in a British shorthair cat: a case report
bullae lobular emphysema spontaneous pneumothorax
2015/12/17
A three-year-old male British shorthair cat that had exhibited progressive lethargy and intermittent
dyspnoea for 14 days was referred for evaluation of acute respiratory deterioration. Clinical fin...
ZERO LOCI OF ADMISSIBLE NORMAL FUNCTIONS WITH TORSION SINGULARITIES
NORMAL FUNCTIONS TORSION SINGULARITIES
2015/9/29
We show that the zero locus of a normal function on a smooth
complex algebraic variety S is algebraic provided that the normal function extends to a admissible normal function on a smooth compacti...
The lameness in a cryptorchid dog with intra-abdominal torsion of one of the two neoplastic testicles:a case report
cryptorchidism canine limp intestitial cell tumour testicular torsion meralgia paresthetica
2015/8/27
This report describes a case of hind limb lameness associated with intra-abdominal torsion of a neoplastic testicle in a dog. An 11-year-old, male, bilaterally cryptorchid dog was referred for third d...
ELLIPTIC CURVES WITH MAXIMAL GALOIS ACTION ON THEIR TORSION POINTS
ELLIPTIC CURVES MAXIMAL GALOIS ACTION TORSION POINTS
2015/8/26
Given an elliptic curve E over a number field k, the Galois action on the torsion points of E induces a Galois representation, ρE : Gal(k/k) → GL2(Z b). For a fixed number field k, we describe the ima...

DRINFELD MODULES MAXIMAL GALOIS ACTION TORSION POINTS
2015/8/26
To each Drinfeld module of generic characteristic defined over a finitely generated field, one can associate a Galois representation arising from the Galois action on its torsion points. Recent work o...

ABELIAN VARIETIES OVER LARGE ALGEBRAIC FIELDS INFINITE TORSION
2015/8/26
Let A be a non-zero abelian variety defined over a number field K and let K be a fixed algebraic closure of K. For each element σ of the absolute Galois group Gal(K/K), let K(σ) be the fixed field in ...
Thoracoscopic-assisted lung lobectomy using hem-o-lok clips in a dog with lung lobe torsion: a case report

2015/4/17
An eleven-year-old, 3-kg, intact female Maltese was presented for depression, anorexia and dyspnoea. Thoracic radiographs showed right-side pleural effusion, a vesicular emphysema pattern and consolid...
Left cranial lung torsion in a Bernese Mountain dog: a case report
lung lobe torsion Bernese dog
2015/4/15
Lung lobe torsion (LLT) is an uncommon pathology in small animal practice. In large breed dogs LLT effects are localized mainly to the middle lobe of the right lung. This report describes a case of le...
