Colemanus keeleyorum (Braconidae, Ichneutinae s. l.): a new genus and species of Eocene wasp from the Green River Formation of western North America

open access: yesJournal of Hymenoptera Research, 2015
A new genus and species of Ichneutinae s. l., Colemanus keeleyorum Fisher, is described from the Eocene Green River Formation in Colorado, USA. Colemanus was placed on a phylogenetic hypothesis using morphological data.

Does Amount of Information Support Aesthetic Values?

open access: yesFrontiers in Neuroscience, 2022
Obtaining information from the world is important for survival. The brain, therefore, has special mechanisms to extract as much information as possible from sensory stimuli.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

open access: yesFEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Panel Unit Root Tests by Combining Dependent 𝑃 Values: A Comparative Study

open access: yesJournal of Probability and Statistics, 2011
We conduct a systematic comparison of the performance of four commonly used 𝑃 value combination methods applied to panel unit root tests: the original Fisher test, the modified inverse normal method, Simes test, and the modified truncated product method (

Fisher hypothesis: UK evidence over a century [PDF]

open access: yesApplied Economics Letters, 2004
Using annual data over a long time horizon from 1900 to 2000 for the UK, this study finds the existence of a Fisher relation via Johansen cointegration tests. The cointegrating relationship between the two variables suggests a significant long-run equilibrium with a positive coefficient of more than one during the stated period.

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

open access: yesFEBS Letters, EarlyView.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Use of higher severity fire areas by female Pacific fishers on the Kern Plateau, Sierra Nevada, California, USA

open access: yesWildlife Society Bulletin, 2015
The Pacific fisher (Pekania pennanti) is a rare and imperiled forest carnivore, with a genetically distinct and isolated population living in the southern Sierra Nevada mountains of California, USA.

Combined Tests of The Fisher and Expectation Hypothesis

open access: yesBrazilian Review of Econometrics, 1989
The role played by in inflationary expectations in the detennination of nominal rates of interest is evaluated within the framework of the Fischer and Expectation Theory of the term structure of interest rates for Argentina during the period June 1977 - June 1982.
