General Split Helicity Gluon Tree Amplitudes in Open Twistor String Theory

, 2010
We evaluate all split helicity gluon tree amplitudes in open twistor string theory. We show that these amplitudes satisfy the BCFW recurrence relations restricted to the split helicity case and, hence, that these amplitudes agree with those of gauge ...

Late‐Holocene evolution of a small Sub‐Arctic glacier, Gljúfurárjökull (Tröllaskagi, northern Iceland)

Boreas, EarlyView.
Gljúfurárjökull, located on the Tröllaskagi Peninsula in northern Iceland, is a small glacier approximately 3.8 km in length. This study analyses the glacier's evolution through a combination of methods including: (i) geomorphological mapping, (ii) Cosmic‐Ray Exposure (CRE) dating, (iii) lichenometry and (iv) palaeoglacier reconstruction (volume ...

Antifungal activity of well-defined chito-oligosaccharide preparations against medically relevant yeasts.

PLoS ONE, 2019
Due to their antifungal activity, chitosan and its derivatives have potential to be used for treating yeast infections in humans. However, to be considered for use in human medicine, it is necessary to control and know the chemical composition of the ...

C32-C36 polymethyl alkenes in Black Sea sediments

Geochimica et Cosmochimica Acta, 1995
A series of novel C32-C36 polymethylhentriacontenes has been identified in near-surface sediments of the Black Sea. Hydrogenation of these components indicated that they possess the 5,8,14,24,27-pentamethyl-, 8,14,24,27-tetramethyl-, 8,14,24-trimethyl-, 8,14-dimethyl-, and 14- and 15-methylhentriacontane C skeletons, which was confirmed by synthesis of

Dynare replication of “A Model of Secular Stagnation: Theory and Quantitative Evaluation” by Eggertsson et al. (2019)

Economic Inquiry, Volume 63, Issue 2, Page 403-423, April 2025.
Abstract This paper replicates the study “A Model of Secular Stagnation: Theory and Quantitative Evaluation” by Eggertsson et al. using the Dynare toolkit. Replication is important as it confirms the results of the original article, provides a user‐friendly version using Dynare, and shows how to deal with large‐scale models with occasionally binding ...

The competitive interplay of 12‐oxophytodienoic acid (OPDA), protein thiols, and glutathione

The FEBS Journal, EarlyView.
12‐Oxophytodienoic acid (OPDA) is a phytohormone involved in plant growth and stress defense. Due to its cyclopentenone moiety, OPDA can form Michael adducts with thiol‐containing compounds such as glutathione and cysteine residues of proteins, resulting in alterations of the cellular redox regulatory network.

A Provincial Perspective of Nonlinear Okun’s Law for Emerging Markets: The Case of South Africa

Studia Universitatis Vasile Goldis Arad, Seria Stiinte Economice, 2020
A provincial analysis of Okun’s law in South Africa is provided in this article from 1996 to 2016. Empirically, we rely on the nonlinear autoregressive distributive lag (N-ARDL) model whilst the Corbae-Ouliaris filter is used to extract the ‘gap ...

The Dependence of the Soft X-ray Properties of LMXBs on the Metallicity of Their Environment

, 1998
We determine the X-ray spectral properties of a sample of low-mass X-ray binaries (LMXBs) which reside in globular clusters of M31, as well as five LMXBs in Galactic globular clusters and in the Large Magellanic Cloud using the ROSAT PSPC.
