2014 Optical pumping of ground state 3He has several peculiar features because nuclear polarization is first obtained in the metastable 2 3S state and then transferred to the ground state (indirect optical pumping); this introduces non-linearities in the equation of evolution of the populations. Here we present a numerical calculation of the kinetics of optical pumping in 3He, which allows a de...

A 73-year-old woman with depressive disorder was found unconscious at home by her daughter, and was admitted to our hospital. On admission, her body temperature was 28.0. Electrocardiogram (ECG) showed sinus bradycardia and prolonged QT interval (Picture 1 left panel). Prominent J wave was found in leads V3-6 (1). The small notch in leads I, III, AVL and V2 was also indicative of J wave (arrows...

Patients that have survived Out-of-Hospital Cardiac Arrest usually develop some degree of neurological problems. A common treatment to mitigate neurological damage is mild therapeutic hypothermia (MTH). However, MTH has adverse effects, including arrhythmia. In order to explore the mechanisms of arrhythmia linked to MTH, we took measures on a temperature controlled experimental model which simu...

We consider the influence of dust charge fluctuations on damping of the dust-ion-acoustic waves. It is assumed that all grains have equal masses but charges are not constant in time they may fluctuate in time. The dust charges are not really independent of the variations in the plasma potentials. All modes will influence the charging mechanism, and feedback will lead to several new interesting ...

Inhomogeneities in wave propagation conditions near and below the solar surface have been detected by means of time-distance helioseismology. Here we calculate the effect of temperature inhomogeneities on the travel times of sound waves. A temperature increase, e.g. in active regions, not only increases the sound speed but also lengthens the path along which the wave travels because the expansi...

[1] There is proxy evidence that the pronounced east-west temperature difference observed today across the equatorial Pacific Ocean may not have existed in the early Pliocene (4–5 Ma BP) and that the east Pacific cold tongue developed gradually toward the end of the Pliocene (2 Ma BP). The east Pacific temperature influences weather and climate worldwide, and the Pliocene climate may be an inst...

[1] Temperature, salinity, velocity, and wind from a mooring at 0 N, 23 Ware used along with satellite data for sea surface temperature and sea level to examine the contribution of tropical instability waves (TIWs) to the energy and heat balance of the equatorial Atlantic mixed layer. The TIWs appear as periodic 20–30 day fluctuations of currents, temperature, and salinity, which intensify begi...

The solutions of a renormalized BCS equation are studied in three space dimensions in s, p and d waves for finite-range separable potentials in the weak to medium coupling region. In the weak-coupling limit, the present BCS model yields a small coherence length ξ and a large critical temperature, Tc, appropriate for some high-Tc materials. The BCS gap, Tc, ξ and specific heat Cs(Tc) as a functi...

The single-electron transistor is the fastest and most sensitive electrometer available today. Single-electron pumps and turnstiles are also being explored as part of the global effort to redefine the ampere in terms of the fundamental physical constants. However, the possibility of electrons tunnelling coherently through these devices, a phenomenon known as co-tunnelling, imposes a fundamental...

Detection of spectral satellite holes by polarization spectroscopy is proposed as a method to measure the line-narrowed eleo tronic absorption spectrum of a large molecule in an amorphous solid at low temperature. The linewidths of the zero-phonon holes yield information about molecular dephasing and the correlation of the inhomogeneous distribution of the two molecular transitions involved in ...
