Recent side-channel attacks on elliptic curve algorithms have shown that the security of these cryptosystems is a matter of serious concern. The development of techniques in the area of Template Attacks makes it feasible to extract a 256-bit secret key with only 257 traces. This paper enhances the applicability of this attack by exploiting both the horizontal leakage of the carry propagation du...

This paper develops a general equilibrium model with the purpose of identifying fundamental determinants of market structure and their welfare impact. The main effects are derived from the interaction between horizontal and vertical differentiation, induced by different sets of exogenous and endogenous sunk costs. The former are found to be positively correlated with market concentration and ma...

In this note the geometry of the indicatrix (I, L̃) is studied as a hypersurface of a complex Finsler space (M,L). The induced Chern-Finsler and Berwald connections are defined and studied. The induced Berwald connection coincides with the intrinsic Berwald connection of the indicatrix bundle. We considered a special projection of a geodesic curve on a complex Finsler space (M,L), called the ind...

We prove a $$C^m$$ Lusin approximation theorem for horizontal curves in the Heisenberg group. This states that every absolutely continuous curve whose velocity is $$m-1$$ times $$L^1$$ differentiable almost everywhere coincides with except on set of small measure. Conversely, we show result no longer holds if differentiability replaced by approximate differentiability. shows our optimal and hig...

0. Introduction. Minimal immersions from a Riemann surface M into Sn were studied by Calabi ([3]) and Chern ([4]), among many authors. To such an immesion F in S4, they found a holomorphic quartic form QF (to be defined in Section 1) on M . A superminimal immersion is one for which QF = 0, which is always the case when M = S 2. In [2], Bryant studied a superminimal immersion of a higher genus i...

OBJECTIVE Data investigating the possible disturbing influence of insulin in the vicinity of continuous glucose monitoring (CGM) is lacking. We investigated the hypothesis that high local insulin concentrations would interfere with sensor readings. RESEARCH DESIGN AND METHODS Two microdialysis sensors were inserted in the periumbilical region of 10 continuous subcutaneous insulin infusion (CS...

Through the establishment of ratary tiller system coordinate system; Firstly giving the analysis of soil grain not heel cover shell collision and the first meeting with cover shell collisions motion situation, through Matlab found the first meeting w...

Pelvic rotation (PR) is commonly seen in patients with idiopathic scoliosis (IS), but factors contributing to this phenomenon and its relationship with the surgical outcome are not well established.This retrospective study included 85 IS patients in 2 groups: thoracic curve dominance group (group A) and lumbar curve dominance group (group B). Pre- and postoperative PR was measured on standing p...

The Horizontal Chord Theorem states that if a continuous curve connects points A and B in the plane, then for any integer k there are points C and D on the curve such that −−→ AB = k −−→ CD. In this note, we discuss a few combinatorial-analysis problems related to this theorem and introduce a different formulation that gives way to generalizations on graphs. 1 THE NECKLACE OF PEARLS PROBLEM.
