Some Like It Hot, Some Like It Warm: Phenotyping To Explore Thermotolerance Diversity [PDF]

open access: yes, 2012
Plants have evolved overlapping but distinct cellular responses to different aspects of high temperature stress. These responses include basal thermotolerance, short- and long-term acquired thermotolerance, and thermotolerance to moderately high ...

Transcriptome analysis identifies genes and co-expression networks underlying heat tolerance in pigs

open access: yesBMC Genetics, 2020
Background Heat stress adversely affects pig growth and reproduction performance by reducing feed intake, weight gain, farrowing rate, and litter size. Heat tolerance is an important characteristic in pigs, allowing them to mitigate the negative effects ...

Tunable stress and controlled thickness modification in graphene by annealing [PDF]

open access: yesACS NaNo 2,1033 (2008), 2008
Graphene has many unique properties which make it an attractive material for fundamental study as well as for potential applications. In this paper, we report the first experimental study of process-induced defects and stress in graphene using Raman spectroscopy and imaging.

Investigation of the Uniformity of Gel Shrinkage by Imaging Tracer Particles Using X‐Ray Microtomography

open access: yesAdvanced Engineering Materials, EarlyView., 2023
A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

Effect of In-vitro Heat Stress Challenge on the function of Blood Mononuclear Cells from Dairy Cattle ranked as High, Average and Low Immune Responders [PDF]

open access: yesBMC Vet Res 17, 233 (2021), 2021
The warming climate is causing livestock to experience heat stress at an increasing frequency. Holstein cows are particularly susceptible to heat stress because of their high metabolic rate. Heat stress negatively affects immune function, particularly with respect to the cell-mediated immune response, which leads to increased susceptibility to disease.

Breaking the Reynolds Analogy: Decoupling Turbulent Heat and Momentum Transport via Spanwise Wall Oscillation in Wall-Bounded Flow [PDF]

open access: yesarXiv, 2023
This work investigates spanwise wall oscillation (SWO) as a method to preferentially enhance heat transfer over drag in turbulent channel flow. Direct numerical simulations at $Re_\tau=180$ and $\Pr=1$ show set of wall-oscillation parameters reducing drag also decrease heat transfer similarly, maintaining coupled transport.

A micro-electro-mechanical-system-based thermal shear-stress sensor with self-frequency compensation [PDF]

open access: yes, 1999
By applying the micro-electro-mechanical-system (MEMS) fabrication technology, we developed a micro-thermal sensor to measure surface shear stress. The heat transfer from a polysilicon heater depends on the normal velocity gradient and thus provides the ...

Analysis of circulating-microRNA expression in lactating Holstein cows under summer heat stress.

open access: yesPLoS ONE, 2020
Korean peninsula weather is rapidly becoming subtropical due to global warming. In summer 2018, South Korea experienced the highest temperatures since the meteorological observations recorded in 1907.

"Reading Between the Heat": Co-Teaching Body Thermal Signatures for Non-intrusive Stress Detection [PDF]

open access: yesarXiv, 2023
Stress impacts our physical and mental health as well as our social life. A passive and contactless indoor stress monitoring system can unlock numerous important applications such as workplace productivity assessment, smart homes, and personalized mental health monitoring. While the thermal signatures from a user's body captured by a thermal camera can

Chaperones as integrators of cellular networks: Changes of cellular integrity in stress and diseases [PDF]

open access: yesIUBMB Life (2008) 60, 10-15, 2007
Cellular networks undergo rearrangements during stress and diseases. In un-stressed state the yeast protein-protein interaction network (interactome) is highly compact, and the centrally organized modules have a large overlap. During stress several original modules became more separated, and a number of novel modules also appear. A few basic functions,
