Building a case for a Planck-scale-deformed boost action: the Planck-scale particle-localization limit

, 2005
"Doubly-special relativity" (DSR), the idea of a Planck-scale Minkowski limit that is still a relativistic theory, but with both the Planck scale and the speed-of-light scale as nontrivial relativistic invariants, was proposed (gr-qc/0012051) as a ...

Quantum Time Uncertainty in a Gravity's Rainbow Formalism [PDF]

, 2004
The existence of a minimum time uncertainty is usually argued to be a consequence of the combination of quantum mechanics and general relativity. Most of the studies that point to this result are nonetheless based on perturbative quantization approaches,

Automated analysis of postictal generalized electroencephalogram suppression for SUDEP risk stratification

Epilepsia Open, EarlyView.
Abstract Sudden unexpected death in epilepsy (SUDEP) affects more than 3000 individuals annually, yet objective and scalable biomarkers to assess risk remain limited. Postictal generalized electroencephalogram suppression (PGES) has been proposed as a potential biomarker, but its quantification is often subjective and variable.

Some Traveling Wave Solutions to the Fifth-Order Nonlinear Wave Equation Using Three Techniques: Bernoulli Sub-ODE, Modified Auxiliary Equation, and G′/G-Expansion Methods

Journal of Mathematics, 2023
The fifth-order nonlinear wave equation contains terms involving higher-order spatial derivatives, such as uxxx and uxxxxx. These terms are responsible for dispersion, which affects the shape and propagation of the wave.

Knot in Cen A: Stochastic Magnetic Field for Diffusive Synchrotron Radiation?

, 2007
The emission of relativistic electrons moving in the random and small-scale magnetic field is presented by diffusive synchrotron radiation (DSR). In this Letter, we revisit the perturbative treatment of DSR.

Mapping Alkyne Chemical Space—Classifying the Reactivity of Alkynes in Semihydrogenation and beyond Using a Data Science Framework

Helvetica Chimica Acta, EarlyView.
A data science framework integrating DFT featurization and hierarchical clustering was used to map the chemical space of over 2700 alkynes into six subsets before using experimental data for Ni3Zn‐catalyzed semihydrogenation and applying a logistic regression model to categorize substrates by reactivity.

Encryption of a Message by HillAli Cipher and Security of Routing Path by DSR in Wireless Sensor Network

Journal of Communications Software and Systems
A Wireless Sensor Network (WSN) is a collection of sensors that communicate or track a specific object. It is used in many fields of war, architecture, or espionage, but the wireless sensor network faces challenges in securing the path or the message ...

Doubly Special Relativity and de Sitter space

, 2003
In this paper we recall the construction of Doubly Special Relativity (DSR) as a theory with energy-momentum space being the four dimensional de Sitter space.

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...
