Rapidly rotating turbulent flow is characterized by the emergence of columnar structures that are representative of quasi-two-dimensional behavior of the flow. It is known that when energy is injected into the fluid at an intermediate scale Lf, it cascades towards smaller as well as larger scales. In this paper we analyze the flow in the inverse cascade range at a small but fixed Rossby number,...

The dielectric relaxation modes in low bismuth doped SrTiO3 were studied at temperatures 1.5–300 K and frequencies up to 1.8 GHz. We observe two modes, at 8 K ~mode I! and 65 K ~mode V!, which also occur in single-crystalline SrTiO3. With Bi doping, two further dielectric peaks, 18 K ~mode II! and 30 K ~mode III!, are induced in both real and imaginary parts of the permittivity on the quantum p...

The membrane-delimited activation of muscarinic K+ channels by G protein beta gamma subunits plays a prominent role in the inhibitory synaptic transmission in the heart. These channels are thought to be heterotetramers comprised of two homologous subunits, GIRK1 and CIR, both members of the family of inwardly rectifying K+ channels. Here, we demonstrate that muscarinic K+ channels in neonatal r...

Recent results from BaBar and Belle experiments on B ¯ B mixing and sin 2φ 1 are presented. Accuracy of ∆m d measurements has reached 1.2%. Higher order effects within the Standard Model or possible new physics effect that might appear in the B ¯ B mixing through non-zero ∆Γ/Γ, CP violation, or CP T violation have been explored. The BaBar and Belle results on sin 2φ 1 from the b → c¯ cs modes a...

Conditions for the establishment of small density perturbations in a self-gravitating two component fluid mixture are studied using a dynamical system approach. It is shown that besides the existence of exponentially growing and decaying modes, which are present for values of the perturbation wave-number k smaller than a critical value k M , two other, pure oscillatory, modes exist at all scale...

Numerical calculations of excess noise factors in low Fresnel number unstable resonators are described in detail. Computed mode profiles in one transverse dimension together with associated Petermann K-factors are presented; dynamical considerations such as injected wave excitation are also examined. The properties of the zero-order modes are consistent with virtual source theory and with a sim...

Far-infrared spectra of ferrimagnetic Dy3Fe5O12 single crystals have been studied in the spectral range between 12 and 700 cm−1 and in a wide temperature range between 5 K and 300 K using transmission spectroscopy and rotating analyzer ellipsometry. In the temperature range below TC = 16 K for the magnetic ordering of Dy3+ spins, a number of ligand field and Kaplan-Kittel (KK) exchange resonanc...

The recently observed B − → K − π 0 , ¯ K 0 π − and ¯ B 0 → K − π + decay modes appear to have nearly equal branching ratios. This suggests that tree and electroweak penguins play an important role, and inclusion of the latter improves agreement between factorization calculation and experimental data.

The far-infrared powder absorption spectra, between 10 cm-’ and 350 cm-‘, of seven BEDT-TTF salts that exhibit superconductivity at or near ambient pressure, have been measured as a function of temperature, between 5 K and 300 K. The temperature dependences of the peak frequencies, along with the measured deuterium isotopic frequency shifts, separated the lattice from the internal modes. The fr...
