Proteins are involved in virtually every biological process and in order to function, it is necessary for these polypeptide chains to fold into the unique, native conformation. This folding process can take place rapidly. NMR line shape analyses and transverse relaxation measurements allow protein folding studies on a microsecond-to-millisecond time scale. Together with an overview of current a...

We suggest that a series of merged interaction regions interacted with the solar wind termination shock for several years prior to its crossing by Voyager 1 in December 2004 and created the observed spectral shape of energetic particles. We also find that the charge-state of He with 3 to 70 MeV/nuc and O with 1 to 14 MeV/nuc is +1 and that the rigidity dependence of the diffusion coefficient fr...

We study collisions between two strongly interacting atomic Fermi gas clouds. We observe exotic nonlinear hydrodynamic behavior, distinguished by the formation of a very sharp and stable density peak as the clouds collide and subsequent evolution into a boxlike shape. We model the nonlinear dynamics of these collisions by using quasi-1D hydrodynamic equations. Our simulations of the time-depend...

Economic crises, natural disasters, armed conflict and infectious disease outbreaks, amongst others, present interlinked challenges for small businesses have generated a recent wealth of research across varied fields. Therefore, this article outlines an analytical lens suggesting how SMEs experience shocks crises that focuses on the nature (i) business, (ii) shock (iii) response within given co...

Introduction: The Shock Compression Laboratory in the Department of Earth and Planetary Sciences at Harvard is a new facility for the study of impact and collisional phenomena. The following describes the experimental capabilities of the laboratory (Fig. 1). Shockwave experiments. The laboratory contains a 40-mm single stage launch system, manufactured by Physics Applications Inc., capable of a...

ABSTRACT We present a new $2\rm \, Ms$Chandra observation of the cluster merger Abell 2146, which hosts two huge M ∼ 2 shock fronts each ${\sim }500\rm kpc$ across. For first time, we resolve and measure width shocks. The best-fitting for bow is $17\pm 1\rm upstream $10.7\pm 0.3\rm kpc$. A narrow collisionless will appear broader in projection if its smooth shape warped by local gas motions. sh...

in this paper we investigate the effect of oil price shocks on stock market index in iran, by using of a structural var (svar) approach. we used four variables in the model namely kilian index, global oil supply, real oil price and real stock market index. the data are monthly and spanning the period 1997m10-2014m12. we identify the effect of four different shocks on stock market including oil ...
