Photon production from an anisotropic quark-gluon plasma [PDF]

open access: yes, 2006
We calculate photon production from a quark-gluon plasma which is anisotropic in momentum space including the Compton scattering and quark/anti-quark annihilation processes.

Hold-up in multiple banking: evidence from SME lending [PDF]

open access: yes, 2010
This paper analyzes loan pricing when there is multiple banking and borrower distress. Using a unique data set on SME lending collected from major German banks, we can instrument for effective coordination between lenders, carrying out a panel estimation.

A discriminating probe of gravity at cosmological scales

open access: yes, 2007
The standard cosmological model is based on general relativity and includes dark matter and dark energy. An important prediction of this model is a fixed relationship between the gravitational potentials responsible for gravitational lensing and the ...

Supplementing risk adjustment with high‐risk pooling using historical data for identifying the high risks

open access: yesJournal of Risk and Insurance, Volume 92, Issue 1, Page 166-202, March 2025.
Abstract Many regulated health insurance markets with community‐rated premiums rely on risk adjustment (RA) to mitigate insurer‐incentives to risk select. However, insurers remain typically undercompensated for chronically ill enrollees. We use historical data on health spending and risk adjuster information to identify individuals undercompensated by ...

An entirely analytical cosmological model

open access: yes, 2008
The purpose of the present study is to show that in a particular cosmological model, with an affine equation of state, one can obtain, besides the background given by the scale factor, Hubble and deceleration parameters, a representation in terms of ...

Cosmological Solutions on Atiyah-Hitchin Space in Five Dimensional Einstein-Maxwell-Chern-Simons Theory

open access: yes, 2010
We construct non-stationary exact solutions to five dimensional Einstein-Maxwell-Chern-Simons theory with positive cosmological constant. The solutions are based on four-dimensional Atiyah-Hitchin space.

Two-Field Quintom Models in the w-w' Plane [PDF]

open access: yes, 2006
The w-w' plane, defined by the equation of state parameter for the dark energy and its derivative with respect to the logarithm of the scale factor, is useful to the study of classifying the dynamical dark energy models.

Registration of ‘Goliath LJ’ and ‘Colossus LJ’ forage soybean cultivars with the long juvenile trait and glyphosate resistance

open access: yesJournal of Plant Registrations, Volume 19, Issue 1, January/April 2025.
Abstract ‘Colossus LJ’ (Reg. no. CV‐563, PI 692622) and ‘Goliath LJ’ (Reg. no. CV‐562, PI 692621) soybean [Glycine max (L.) Merr.] cultivars were developed by the Clemson University Pee Dee Research and Extension Center in Florence, SC, and released as forage maturity group (MG) VII and MG VIII glyphosate‐tolerant cultivars, respectively. After release,

Reply to `Can infrared gravitons screen $\Lambda$?'

open access: yes, 2008
We reply to the recent criticism by Garriga and Tanaka of our proposal that quantum gravitational loop corrections may lead to a secular screening of the effective cosmological constant.

Molecular and functional in vivo characterisation of murine Dectin‐1 isoforms

open access: yesEuropean Journal of Immunology, Volume 54, Issue 11, November 2024.
Dectin‐1 is a C‐type lectin receptor for the innate sensing of fungi. This receptor exists in two major isoforms in mice differing in a stalk domain, which determines their degradative pathway. Here, we characterise the properties of the two isoforms in a cellular context and using a newly established in vivo model. Abstract Dectin‐1 is a C‐type lectin‐
