Evaluative conditioning induces changes in sound valence

open access: yesFrontiers in Psychology, 2012
Evaluative Conditioning (EC) has hardly been tested in the auditory domain, but it is a potentially valuable research tool. In Experiment 1 we investigated whether the affective evaluation of short environmental sounds can be changed using affective ...

Experimental extraction of effective refractive index and thermo-optic coefficients of silicon-on-insulator waveguides using interferometers [PDF]

open access: yes, 2015
We propose and demonstrate an accurate method of measuring the effective refractive index and thermo-optic coefficient of silicon-on-insulator waveguides in the entire C-band using three Mach-Zehnder interferometers.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

A Compact Triple-Band Negative Permittivity Metamaterial for C, X-Band Applications

open access: yesInternational Journal of Antennas and Propagation, 2017
We report a new design of triple-band electric metamaterial resonator (TBEMR) based on integration of open delta loops within square ring resonator. This metamaterial resonator has three distinct ε-negative regions (ENG) over C, X frequency bands.

A dual band left-handed metamaterial-enabled design for satellite applications

open access: yesResults in Physics, 2020
The focus of this research paper is to produce a novel left-handed metamaterial design for satellite frequency application. The broad usage of metamaterial in satellite application results in the creation of a compact and dual band exotic material. A new

A systematic TMRT observational study of Galactic $^{12}$C/$^{13}$C ratios from Formaldehyde

open access: yes, 2019
We present observations of the C-band $1_{10}-1_{11}$ (4.8 GHz) and Ku-band $2_{11}-2_{12}$ (14.5 GHz) K-doublet lines of H$_2$CO and the C-band $1_{10}-1_{11}$ (4.6 GHz) line of H$_2$$^{13}$CO toward a large sample of Galactic molecular clouds, through ...

Mechanisms of parasite‐mediated disruption of brain vessels

open access: yesFEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

A New Triple Band Microstrip Fractal Antenna for C-band and S-band Applications

open access: yesJournal of Microwaves, Optoelectronics and Electromagnetic Applications
Recently research show that some parameters such as the shapes of antenna patch and the ground plane when geometrically altered produces changes in the current density distribution of the planar structure and consequently in the resonant modes.
