Laser Measurement of Building Vibration and Displacement

open access: yesShock and Vibration, 2000
This paper considers four laser systems used by the Building Research Establishment (BRE) to investigate the behaviour of structures. Lasers enable remote measurements of vibration and displacement to be taken where access to a structure is difficult or ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

All-fiber multimode interference micro-displacement sensor [PDF]

open access: yes, 2013
We report an all-fiber micro-displacement sensor based on multimode interference (MMI) effects. The micro-displacement sensor consists of a segment of No-Core multimode fiber (MMF) with one end spliced to a segment of single mode fiber (SMF) which acts ...

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 ...

MEASURING THE DISPLACEMENT AND REPLACEMENT OF GOVERNMENT HEALTH EXPENDITURE [PDF]

open access: yesHealth Economics, 2013
ABSTRACTResearch assessing the relationship between government health expenditure and development assistance for health channeled to governments (DAHG) has not considered that this relationship may depend on whether DAHG is increasing or decreasing. We explore this issue using general method of moments estimation and a panel of financial flows data ...

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Metasurface-enabled achromatic high-precision optical displacement sensor

open access: yesAPL Photonics
Optical displacement sensors are widely employed in various fields due to their broad measurement range, high resolution, and exceptional precision. However, their sensitivity and measurement accuracy are inherently limited by the frequency stability of ...

High-precision non-contact probes based on spectral confocal technology

open access: yesJournal of Measurement Science and Instrumentation, 2023
To solve the problems of small measurement range and poor accuracy of the spectral confocal non-contact probes, a four-piece lens group with a large measurement range is designed.
