Self-Supervised Deep Convolutional Neural Network for Chest X-Ray Classification
IEEE Access, 2021 Chest radiography is a relatively cheap, widely available medical procedure that conveys key information for making diagnostic decisions. Chest X-rays are frequently used in the diagnosis of respiratory diseases such as pneumonia or COVID-19.

Oxyfuel Combustion in IC Engines
, 2023 This chapter introduces principles, mixing, ignition and combustion and controls processes of oxyfuel combustion which aims to achieve CCS (Carbon Capture and Storage) in IC (Internal Combustion) engines. By replacing air with pure oxygen and using hot and/or cooled EGR as dilutant gas for controlling the combustion process and flame speed, the mixing ...

Experimental and numerical modeling of high speed ice impact onto rigid target [PDF]
, 2015 The core goal of this research is to develop an ice impact modelling methodology for ice impact on aircraft structures. The main current limitation of ice impact analysis is the ice constitutive model, so this research is focussed on the assessment and ...

Estimation of stresses in atmospheric ice during aeolian vibration of power transmission lines [PDF]
, 2010 Aeolian vibration in bare and iced cable was simulated using the theory of cable vibration. High frequency vibration creates stresses in the cable and consequently in the ice covering that cable, which may result in ice failure and eventually ice ...

Instrumented concrete pile tests – part 2: strain interpretation
, 2022 The incorporation of strain gauges (traditionally electrical resistance and vibrating wire gauges but increasingly fibre optic sensors) within concrete piles enables an enhanced understanding of the shear stress distribution along the pile shaft and the ...

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 ...

Instrumented concrete pile tests – part 1: a review of instrumentation and procedures
, 2022 Preliminary pile tests are becoming increasingly routine in piling projects, some of which are instrumented to help optimise working pile design. However, the execution of a successful test on an instrumented concrete pile (ICP) is not straightforward ...

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila
FEBS Letters, EarlyView.Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

Engineering Properties of Sea Ice [PDF]
Journal of Glaciology, 1977 AbstractAs the continental shelves of the Arctic become important as source areas for the oil and minerals required by human society, sea ice becomes an increasing challenge to engineers. The present paper starts with a consideration of the different fields of engineering which require information on sea ice with the tasks ranging from the design of ...
