Temperature Dependent Polarity Reversal in Au/Nb:SrTiO3 Schottky Junctions
, 2007 We have observed temperature-dependent reversal of the rectifying polarity in Au/Nb:SrTiO3 Schottky junctions. By simulating current-voltage characteristics we have found that the permittivity of SrTiO3 near the interface exhibits temperature dependence ...

Magnetostratigraphy of the Lower Triassic beds from Chaohu(China) and its implications for the Induan–Olenekian stage boundary. [PDF]
, 2009 A magnetostratigraphic study was performed on the lower 44 m of the West Pingdingshan section near Chaohu city, (Anhui province, China) in order to provide a magnetic polarity scale for the early Triassic.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Mathematical modeling of mechanosensitive reversal control in Myxococcus xanthus
Frontiers in MicrobiologyAdjusting motility patterns according to environmental cues is important for bacterial survival. Myxococcus xanthus, a bacterium moving on surfaces by gliding and twitching mechanisms, modulates the reversal frequency of its front-back polarity in ...

Indonesian Journal on Geoscience, 2014 DOI: 10.17014/ijog.v5i2.99Palaeomagnetism has a role to make a new stratigraphic nomenclature based on the earth magnetism of a nonperiodic reversal polarity phenomenon. Since this phenomenon has a global impact, it can be used as a potential correlation,

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Unusual Polar Conditions in Solar Cycle 24 and their Implications for Cycle 25
, 2016 We report on the prolonged solar-maximum conditions until late 2015 at the north-polar region of the Sun indicated by the occurrence of high-latitude prominence eruptions and microwave brightness temperature close to the quiet Sun level.

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Power reversal strategy through DC current reversal using a new bidirectional LCC HVDC system
International Journal of Electrical Power & Energy SystemsThis paper presents a new Line-Commutated Converter (LCC) High-Voltage Direct Current (HVDC) topology with bidirectional current capability. Based on the proposed topology, this paper further develops a control strategy that achieves power reversal ...
