In fission yeast, microtubules push against the cell edge, thereby positioning the nucleus in the cell center. Kinesin-8 motors regulate microtubule catastrophe; however, their role in nuclear positioning is not known. Here we develop a physical model that describes how kinesin-8 motors affect nuclear centering by promoting a microtubule catastroph...

In this paper, we analyse the influence of near-surface anomalies on the first arrivals of seismic waves. The traveltimes of first arrivals are calculated using the eikonal equation and are depicted in the form of the time–distance (t–x) graphs. We classify five simple geological models according to the shape of the t–x graphs and relate these resu...

In this paper we investigate the influence of near-surface anomalies on the first arrivals of seismic waves. The basic two-layer model is modified with the following anomalies: (1) circular cavity positioned in the upper layer, (2) buried circular object positioned in the upper layer, (3) part of the border between the layers is deformed into conca...

Cell polarity can be influenced by an electric field, but the mechanisms behind this response are poorly understood. A new paper shows that fission yeast cells change their direction of growth in an external electric field and suggests mechanisms based on the cortical pH gradient and on electrophoresis of membrane proteins.

The position of a division site in the rod-shaped bacterium E. coli is partially determined by pole-to-pole oscillations of the Min-family of proteins—MinC, MinD, and MinE. Furthermore, experiments reveal that MinD protein polymerizes on the membrane into filaments and that MinE protein forms an oscillating ring. We assume that MinD filaments are s...

We introduce a three-dimensional stochastic reaction-diffusion model to describe MinD/MinE dynamical structures in Escherichia coli. This model spontaneously generates pole-to-pole oscillations of the membrane-associated MinD proteins, MinE ring, as well as filaments of the membrane-associated MinD proteins. Experimental data suggest MinD filaments...

The odd-even nucleus 125Ce was studied via in-beam γ-ray spectroscopy using the 40Ca + 92Mo reaction at 190 MeV. Four rotational bands were observed, two of them being identified for the first time. New connecting transitions were identified between the bands, which leads to new spin assignment for one of the previously known bands. We propose J =...

The structures of high spin states in neutron-deficient nuclei below the Sn isotope chain close to doubly-magic 100Sn are dominated by the interplay between proton holes in the g9/2 orbit and neutrons distributed over several single-particle orbits between the N = 50 and N = 82 shell closures. In nuclei close to 100Sn, this interplay can be either...

Main features and some recent results of our calculations in the Interacting boson plus broken pair model (IBBPM) for even-even, Interacting boson fermion plus broken pair model (IBFBPM) for odd-even and Interacting boson fermion fermion model (IBFFM) for odd-odd nuclei are presented. Recently we have performed extensive calculations of excitation...

The recoil-distance Doppler-shift and Doppler-shift attenuation techniques were employed to determine for the first time lifetimes of high-spin states in 104Cd in the time range 0.3 ps<~τ<~1.2 ns. The nuclei were populated using the compound nucleus reaction 58Ni(50Cr, 4p) and the γ radiation from their decay was detected with the GASP spectrometer...

Excited states of 65Ga and 67Ga nuclei were populated through the 12C(58Ni,αp) and 12C(58Ni,3p) reactions, respectively, and investigated by in-beam γ-ray spectroscopic methods. The NORDBALL array equipped with a charged particle ball and 11 neutron detectors was used to detect the evaporated particles and γ rays. The level schemes of 65,67Ga were...

The 72As nucleus was studied via the (alpha,ngamma) reaction at 14.2 MeV bombarding energy. Single gamma-, gammagamma-coincidence, and internal conversion electron spectra were measured with Ge(HP) gamma-ray and superconducting magnetic lens plus Si(Li) electron spectrometers. On the basis of the internal conversion coefficients of 72As transitions...
