Electron and photon structure functions at two loops
We present a fully analytic computation of the complete electron and photon structure functions, or QED lepton parton distribution functions (PDFs) up to two-loop order.

ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

Entanglement and Bell nonlocality in τ + τ − at the BEPC
Quantum entanglement and Bell nonlocality are two phenomena that occur only in quantum systems. In both cases, these are correlations between two subsystems that are classically absent.

ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.

Laser-assisted Light-by-light scattering in Born-Infeld and axion-like particle theories
The precision measurements of well-known light-by-light reactions lead to important insights of nonlinear quantum electrodynamics (QED) vacuum polarization.

Chemical Shift Separated and Compensated Ultra‐Short Echo‐Time Imaging
ABSTRACT Purpose To develop a modified binomial excitation scheme for ultra‐short echo‐time (UTE) imaging that allows for the separation of water and fat signals and the correction of chemical shift artifacts. Methods Theoretical derivation and numerical Bloch simulations were performed for a modified water‐excitation binomial pulse scheme to calculate

Quantum Information Measures of a Dirichlet Waveguide with Neumann Window(s)
ABSTRACT Engineering boundary conditions in low‐dimensional structures provides a simple yet powerful way of shaping how quantum information is stored and transported. We investigate a flat 2D Dirichlet waveguide containing one or two finite Neumann windows and compute the bound states in both position and momentum space as functions of the window ...

A Theory of the Boundaries of Banks With Implications for Financial Integration and Regulation
ABSTRACT We offer a theory of the “boundary of the firm” that is tailored to banks, recognizing the relevance of deposit financing and interbank lending as a substitute for integration. It is based on a single inefficiency that has been at the core of banking theory: risk‐shifting incentives in the interest of bank shareholders.

Neutrino trident scattering at near detectors
Neutrino trident scattering is a rare Standard Model process where a charged-lepton pair is produced in neutrino-nucleus scattering. To date, only the dimuon final-state has been observed, with around 100 total events, while the other channels are as yet

ChemBang: Expanding the Chemical Space Around Small Molecules
Schematic diagram of the underlying concepts behind ChemBang and the molecular generation process from a seed molecular structure by applying the three main categories of chemical transformations, namely, interchange of small substituents, replacement of ring systems, and scaffold enlargement by additional ring systems.
