Conformity

Conformity

Conformity is the change in a person’s behavior to go along with the group, even if that person does not agree with the group.

Conformations of Butane

Conformations of Butane

Unlike ethane and propane that have only two major conformations, butane has more than two conformers. The staggered form of butane in which the bulky methyl groups on the two carbons are placed on opposite sides, that is, at a dihedral angle of 180°, is the lowest energy, most stable form — called the anti conformer. This conformation is stabilized due to the absence of steric repulsion between the largely spaced out methyl groups. The other two staggered conformations are...

Long-patch Base Excision Repair

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Conformations of Cycloalkanes

Conformations of Cycloalkanes

Adolf von Baeyer attempted to explain the instabilities of small and large cycloalkane rings using the concept of angle strain — the strain caused by the deviation of bond angles from the ideal 109.5° tetrahedral value for sp3 hybridized carbons. However, while cyclopropane and cyclobutane are strained, as expected from their highly compressed bond angles, cyclopentane is more strained than predicted, and cyclohexane is virtually strain-free. Hence, Baeyer’s theory that...

Conformations of Cyclohexane

Conformations of Cyclohexane

Cyclohexane does not exist in a planar form due to the high angle and torsional strain it would experience in the planar structure. Instead, it adopts non-planar chair and boat conformations.
The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal...

Conformations of Ethane and Propane

Conformations of Ethane and Propane

In an organic molecule, free rotation about the carbon-carbon single bond results in energetically different conformers of the molecule. Due to this rotation, called the internal rotation, ethane has two major conformations — staggered and eclipsed.
Staggered conformation is a low energy and more stable conformation with the C-H bonds on the front carbon placed at 60°dihedral angles relative to the C-H bonds on the back carbon, leading to a reduced torsional strain. In staggered...

Background:

High-density electromyography (HD-sEMG) requires reliable electrode-skin contact.
Integrating HD-sEMG with ultrasound imaging presents challenges due to probe and electrode interference.

Purpose of the Study:

To develop and validate a novel dry electrode grid (ReGrid) for HD-sEMG that is highly conformable and ultrasound-transparent.
To assess the feasibility of simultaneous HD-sEMG and ultrasound acquisition using ReGrid.

Main Methods:

Fabrication of a thin-film polyurethane membrane with inkjet-printed silver electrodes and traces.
Mechanical conformability and ultrasound transparency testing.
In-vivo evaluation on tibialis anterior muscle, recording HD-sEMG signals with and without an ultrasound probe.

Main Results:

ReGrid demonstrated excellent conformability to curved surfaces and complete ultrasound transparency without artifacts.
Low and stable electrode-skin impedance with noise levels comparable to gel-based electrodes.
Simultaneous HD-sEMG and ultrasound acquisition showed no significant impact on signal quality, conduction velocity, or decomposition outcomes.

Conclusions:

ReGrid is a viable technology for combined HD-sEMG and ultrasound applications.
The electrode's properties enable novel integrated imaging and electrophysiological assessments.
This facilitates advanced research in areas like 3D and panoramic ultrasound integrated with HD-sEMG.
