Pondering over Focus on Form and Focus on FormS: Are There “Equivalent and Large Effects”?

open access: yesStudies in Applied Linguistics & TESOL, 2007
It is reassuring that Norris and Ortega's (2000) study echoes Long's (1983, as cited in Han, 2004) finding that instruction does positively impact classroom L2 acquisition, provided that appropriate instruction is implemented.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

The strong Popov form of nonlinear input–output equations; pp. 193–206 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2018
The equivalence transformations are applied to bring a system of nonlinear input–output (i/o) equations into a nonlinear equivalent of the Popov form, called the strong Popov form, under the assumption that the i/o equations already are in the strong ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

On a new discrete Mulholland-type inequality in the whole plane

open access: yesJournal of Inequalities and Applications, 2018
A new discrete Mulholland-type inequality in the whole plane with a best possible constant factor is presented by introducing multi-parameters, applying weight coefficients, and using Hermite–Hadamard’s inequality.

Utility Functions of Equivalent Form and the Effect of Parameter Changes on Optimum Decision Making [PDF]

open access: yes
We derive a class of utility functions that are equivalent with respect to a well-defined functional form. We study the case of constant relative risk aversion (of some order) to investigate on different equivalence relations in order to determine the ...

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Equivalent properties of a Mulholland-type inequality with a best possible constant factor and parameters

open access: yesJournal of Inequalities and Applications, 2019
By means of the weight coefficients, using the idea of introduced parameters and the techniques of real analysis, a Mulholland-type inequality with a homogeneous kernel and an equivalent form are provided.

On equivalence of binary forms

open access: yesJournal of Number Theory, 1983
AbstractIn this paper the question of equivalence of two binary forms is related to certain properties of the roots. A method is given to determine whether or not two forms are equivalent. This method applies to a wide class of forms, though not all.
