Temperature-driven differential gene expression by RNA thermosensors
Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2014Many prokaryotic genes are organized in operons. Genes organized in such transcription units are co-transcribed into a polycistronic mRNA. Despite being clustered in a single mRNA, individual genes can be subjected to differential regulation, which is mainly achieved at the level of translation depending on initiation and elongation.

Graded Structural Polymorphism in a Bacterial Thermosensor Protein
Journal of the American Chemical Society, 2017Thermosensing is critical for the expression of virulence genes in pathogenic bacteria that infect warm-blooded hosts. Proteins of the Hha-family, conserved among enterobacteriaceae, have been implicated in dynamically regulating the expression of a large number of genes upon temperature shifts.

Unique temperature-activated neurons from pit viper thermosensors
American Journal of Physiology-Cell Physiology, 2004Rattlesnakes, copperheads, and other pit vipers have highly sensitive heat detectors known as pit organs, which are used to sense and strike at prey. However, it is not currently known how temperature change triggers cellular and molecular events that activate neurons supplying the pit organ.

Nanosized Thermosensors for Use in Explosions
MRS Proceedings, 2013ABSTRACTNanophase Eu-doped Y2(CO3)3 and Eu-doped Zr(OH)4 are seeded into explosive fireballs to record the temperatures inside the fireball. The heat from the explosion decomposes the materials and converts them into Eu-doped Y2O3 and Eu-doped ZrO2, respectively.

Microwave Power Mount Using a Quartz Thermosensor
IEEE Transactions on Instrumentation and Measurement, 1975A new-type power mount is developed which is capable of measuring microwave or millimeter-wave power using a quartz-crystal thermal sensor as the power detector. The principle of this power mount and experimental results are given.

Submicron QDs-containing Particles as Nano-thermosensors
Materials Today: Proceedings, 2016We have developed a facile approach to engineering ratiometric sensors nano-thermosensors (NTSs) with a core/shell structure. A layer of “smart” thermosensitive poly(N-vinylcaprolactam) doped with quantum dots (QDs) with the emission wavelength λem shell makes it possible to obtain fluorescence emission depending on temperature.

Thermosensor präzisiert die zyklische Werkzeug-Temperierung
Konstruktion, 2019Wenn in der Kunststofftechnik hochwertige Oberflächen oder feine Mikrostrukturen erzielt werden sollen, setzen Werkzeugbauer und Spritzgießer auf das „Z-System“ von Hotset. Gerade in der Serienproduktion von Formteilen für Consumer-Industrie und Automobilbau bietet diese hochflexible Lösung für die partielle und zyklische Kavitäten-Temperierung ...

Two thermosensors in Drosophila have different behavioral functions
Journal of Comparative Physiology A: Sensory, Neural, and Behavioral Physiology, 2001Insects inhabit extreme temperature environments and have evolved mechanisms to survive there. Small insects are especially susceptible to rapid changes in body temperature. Therefore, the rapid detection of environment and body temperature is important for their survival. Little, however, is known about the thermosensors that detect those temperatures.

Thermosensor diagnostics (TSD) of laser welding process
2010 International Conference on Advanced Optoelectronics and Lasers, 2010Hardware and software means of laser welding process monitoring were developed and tested in a couple of industrial application - both with pulse and cw lasers. Factors and criteria of thermodynamic stability for metal melting and seam forming thermal fields are discussed.
