The precise knowledge of the QED initial state corrections is instrumental importance in studying high luminosity measurements $e^+e^-$ annihilation at facilities like LEP, International Linear Collider ILC, CLIC, a Giga-$Z$ facility, and planned FCC\_ee. Logarithmic up to $O(\alpha^6 L^5)$ are necessary with various subleading terms taken into account. This applies both inclusive measurement p...

Chloride intracellular channel proteins (CLICs) are multi-functional proteins that are expressed in various cell types and differ in their subcellular location. Two CLIC homologs, EXL-1 (excretory canal abnormal like-1) and EXC-4 (excretory canal abnormal- 4), are encoded in the Caenorhabditis elegans genome, providing an excellent model to study the functional diversification of CLIC proteins....

OBJECTIVES Few studies have investigated cognitive factors affecting learning of procedural skills in medical education. Cognitive load theory, which focuses on working memory, is highly relevant, but methods for measuring cognitive load during procedural training are not well understood. Using colonoscopy as an exemplar, we used cognitive load theory to develop a self-report instrument to meas...

We study the effects of non-commutative QED (NCQED) in fermion pair production, γ + γ → f + f̄ and Compton scattering, e + γ → e + γ. Noncommutative geometries appear naturally in the context of string/M-theory and gives rise to 3and 4-point photon vertices and to momentum dependent phase factors in QED vertices which will have observable effects in high energy collisions. We consider ee collide...

We consider the separate effects on four fermion processes, in the TeV energy range, produced at one loop by Sudakov logarithms of universal and not universal kind, working in the 't Hooft ξ = 1 gauge. Summing the various vertex and box contributions allows to isolate two quite different terms.The first one is a combination of vertex and box quadratic and linear logarithms that are partially un...
