Dual-mode operation of a neutron source, a concept [PDF]
, 1969 Pulsed neutron source operates in conjunction with a photomultiplier tube coupled to a gamma ray scintillation crystal. This allows measurements of gamma radiation from both inelastic scattering and thermal neutron capture in a single ...

AAA+ protein unfoldases—the Moirai of the proteome
FEBS Letters, EarlyView.AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

International Review of Research in Open and Distributed Learning, 2002 When it was created in 1995, the Universitat Oberta de Catalunya (UOC) served only 200 students and offered two degrees. Today, it has expanded its activities to serve over 20,000 students and 16 official degrees. UOC also offers more than 250 continuing

Metasurface Design for Dual-Mode Sensors Based on Broken Symmetry Structure
NanomaterialsDual-mode sensors are currently facing difficulties in achieving independent sensing of parameters as well as low sensitivity. In this paper, we propose a dual-mode sensor using the finite element method (FEM) based on a coupled silver–PDMS–gold (SPG ...

Thermal Control of a Dual Mode Parametric Sapphire Transducer
, 2009 We propose a method to control the thermal stability of a sapphire dielectric transducer made with two dielectric disks separated by a thin gap and resonating in the whispering gallery (WG) modes of the electromagnetic field. The simultaneous measurement

Electronics Letters, 2019 This Letter proposes a balanced dual‐mode substrate integrated waveguide (SIW) filter for the first time. Based on dual‐mode square SIW cavities, perturbation vias, and balanced ports, the quasi‐elliptic differential mode response with improved selectivity as well as high‐performance common mode suppression can be obtained conveniently.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
