The Proliferation of Definitions of Terrorism in International Law

open access: yesContemporary Challenges, 2020
This paper analyses the proliferation of definitions of terrorism in international law and across national jurisdictions. On the one hand, this paper argues that terrorism legislation mainly pursues a symbolic function in international and criminal law ...

Retinal Expression of the Drosophila eyes absent Gene Is Controlled by Several Cooperatively Acting Cis-regulatory Elements. [PDF]

open access: yesPLoS Genetics, 2016
The eyes absent (eya) gene of the fruit fly, Drosophila melanogaster, is a member of an evolutionarily conserved gene regulatory network that controls eye formation in all seeing animals.

Exact Chern-Simons / Topological String duality

open access: yes, 2015
We invoke universal Chern-Simons theory to analytically calculate the exact free energy of the refined topological string on the resolved conifold. In the unrefined limit we reproduce non-perturbative corrections for the resolved conifold found elsewhere

Rapid Micro-Motion Feature Extraction of Multiple Space Targets Based on Improved IRT

open access: yesRemote Sensing
Micro-motion feature extraction is of great significance for target recognition. However, traditional methods mostly focus on single target and struggle to correctly separate the severely overlapping micro-motion curves of multiple targets. In this paper,

Integrated Design of Multi-Constrained Snake Maneuver Surge Guidance Control for Hypersonic Vehicles in the Dive Segment

open access: yesAerospace, 2023
Focusing on the large maneuver penetration of the hypersonic glide vehicle with multiple constraints and uncertain disturbance, a robust integrated guidance and control law, which can achieve the snake-shape maneuver, is designed.

Unconstrained Astrometric Orbits for Hipparcos Stars with Stochastic Solutions [PDF]

open access: yes, 2006
A considerable number of astrometric binaries whose positions on the sky do not obey the standard model of mean position, parallax and linear proper motion, were observed by the Hipparcos satellite.

Multiple zeta functions: the double sine function and the signed double Poisson summation formula [PDF]

open access: yesCompositio Mathematica, 2004
Summary: We construct multiple zeta functions as absolute tensor products of usual zeta functions. The Euler product expression is established for the most basic case \(\zeta(s,\mathbb F_p)\otimes \zeta(s,\mathbb F_q)\) by using the signed double Poisson summation formula and the theory of the double sine function.

Exploring Physics-Informed Neural Networks for the Generalized Nonlinear Sine-Gordon Equation

open access: yesApplied Computational Intelligence and Soft Computing
The nonlinear sine-Gordon equation is a prevalent feature in numerous scientific and engineering problems. In this paper, we propose a machine learning-based approach, physics-informed neural networks (PINNs), to investigate and explore the solution of ...

High-Copy Transposons from a Pathogen Give Rise to a Conserved sRNA Family with a Novel Host Immunity Target

open access: yesMolecular Plant-Microbe Interactions
Small RNAs (sRNAs) are involved in gene silencing in multiple ways, including through cross-kingdom transfers from parasites to their hosts. Little is known about the evolutionary mechanisms enabling eukaryotic microbes to evolve functional mimics of ...

Log-sine evaluations of Mahler measures

open access: yes, 2010
We provide evaluations of several recently studied higher and multiple Mahler measures using log-sine integrals. This is complemented with an analysis of generating functions and identities for log-sine integrals which allows the evaluations to be ...
