Universal Minimum Heat Leak on Low-Temperature Metallic Electrical Leads
, 2006 Low-temperature electronic systems require electrical leads which have low electrical resistance to provide bias current I without excessive voltage drop V. But proper cryogenic design also requires high thermal resistance to maintain a minimum heat leak

Multiomics analysis reveals that microbiota regulate fat and muscle synthesis in chickens
Poultry Science: Intestinal microbiota regulates the host metabolism, including fat metabolism and muscle development in mammals; however, studies on the interactions between the gut microbiome and in chickens with respect to fat metabolism and muscle development are ...

Brassinosteroids participate in the control of basal and acquired freezing tolerance of plants [PDF]
, 2016 Brassinosteroids (BRs) are growth-promoting plant hormones that play a role in abiotic stress responses, but molecular modes that enable this activity remain largely unknown. Here we show that BRs participate in the regulation of freezing tolerance.

Optimization of leaf morphology in relation to leaf water status: A theory. [PDF]
, 2020 The leaf economic traits such as leaf area, maximum carbon assimilation rate, and venation are all correlated and related to water availability. Furthermore, leaves are often broad and large in humid areas and narrower in arid/semiarid and hot and cold ...

Joining lead wires to thin platinum alloy films [PDF]
, 1983 A two step process of joining a lead wire to .000002 m thick platinum alloy film which rests upon an equally thin alumina insulating layer which is adhered to a metal substrate is described.

Normal metal - superconductor tunnel junction as a Brownian refrigerator [PDF]
, 2007 Thermal noise generated by a hot resistor (resistance $R$) can, under proper conditions, catalyze heat removal from a cold normal metal (N) in contact with a superconductor (S) via a tunnel barrier. Such a NIS junction acts as Maxwell's demon, rectifying

Medium-frequency electrical resistance sintering of oxidized C.P. iron powder [PDF]
, 2018 Commercially pure (C.P.) iron powders with a deliberate high degree of oxidation were consolidated by medium-frequency electrical resistance sintering (MF-ERS). This is a consolidation technique where pressure, and heat coming from a low-voltage and high-
