Intensive leak standards for helium leak detection
Journal of Physics: Conference Series, 2021 Abstract The article discusses the main reasons for the demand for gas leak standards with a flow range of 5⋅10-7 to 5⋅10-4 Pa⋅m3/s, for helium leak detection. The high flow Leak Standards Vactron VKT are presented.

Enhanced leak detection in water distribution systems using GFCC-based signal processing techniques
Physics OpenLeak detection in water distribution systems remains a significant challenge, especially for small-scale leaks masked by noise. This study proposes an advanced signal processing approach using Gammatone Frequency Cepstral Coefficients (GFCC) combined ...

Use of PVDF Wire Sensors for Leakage Localization in a Fluid-Filled Pipe
Sensors, 2020 The detection and location of pipeline leakage can be deduced from the time difference between the arrival leak signals measured by sensors placed at the pipe access points on either side of a suspected leak.

Data Leak Detection as a Service [PDF]
, 2013 We describe a network-based data-leak detection (DLD) technique, the main feature of which is that the detection does not reveal the content of the sensitive data. Instead, only a small amount of specialized digests are needed. Our technique – referred to as the fuzzy fingerprint detection – can be used to detect accidental data leaks due to human ...

Pressure Change Leak Detection Based on Lagrange Interpolation Formula
SICE Journal of Control, Measurement, and System Integration, 2017 The pressure change method of leak testing has the serious disadvantage of being susceptible to ambient temperature change. Two or more successive leak tests are typically performed to eliminate the error caused by such change.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes
FEBS Letters, EarlyView.Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

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 ...
