Fermionic greybody factors of two and five-dimensional dilatonic black holes [PDF]
We study fermionic perturbations in the background of a two and five-dimensional dilatonic black holes. Then, we compute the reflection and transmission coefficients and the absorption cross section for fermionic fields, and we show numerically that the ...

Sparse Signals in the Cross‐Section of Returns
This paper uses a penalized regression known as the LASSO to identify rare, short-lived, “sparse” signals in the cross-section of returns. The LASSO boosts out-of-sample predictability in one-minute returns by 23% relative to OLS regressions. This out-of-

Total top-quark pair-production cross section at hadron colliders through O(αS(4)). [PDF]
We compute the next-to-next-to-leading order (NNLO) quantum chromodynamics (QCD) correction to the total cross section for the reaction gg → tt + X. Together with the partonic channels we computed previously, the result derived in this Letter completes ...

Background Prior systematic reviews highlight that accessing specialist healthcare to treat chronic conditions can be obstructed by variations in referral rates, inappropriate referrals, and poor communication.

242Pu absolute neutron-capture cross section measurement
The absolute neutron-capture cross section of 242Pu was measured at the Los Alamos Neutron Science Center using the Detector for Advanced Neutron-Capture Experiments array along with a compact parallel-plate avalanche counter for fission-fragment ...

Ultrahigh-Energy Neutrino-Nucleon Cross Sections and Perturbative Unitarity [PDF]
Unitarity relates the total cross section for neutrino-nucleon scattering to the neutrino-nucleon forward scattering amplitude. Assuming the validity of the perturbative expansion of the forward amplitude in the {\em weak} coupling constant, we derive a ...

ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...

Investigation of elastic scattering cross-sections of electron with neon atoms
In the present study, Integral [QI(E)], Momentum transfer [QM(E)] and Total [QT(E)] cross-sections have been successfully determined for the elastic scattering of electrons with Neon (Ne) atoms in intermediate incident energy range (100 – 500 eV).

Towards the high-accuracy determination of the 238U fission cross section at the threshold region at CERN - N-TOF [PDF]
The 238U fission cross section is an international standard beyond 2 MeV where the fission plateau starts. However, due to its importance in fission reactors, this cross-section should be very accurately known also in the threshold region below 2 MeV ...
