Wave excitations of drifting two-dimensional electron gas under strong inelastic scattering

open access: yes, 2012
We have analyzed low-temperature behavior of two-dimensional electron gas in polar heterostructures subjected to a high electric field. When the optical phonon emission is the fastest relaxation process, we have found existence of collective wave-like ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Liquefaction Potential of Silty Sand in Simple Shear [PDF]

open access: yesMehran University Research Journal of Engineering and Technology, 2013
In this paper, the liquefaction potential of medium dense and dense sand layers was studied by performing constant volume (undrained) cyclic simple shear tests using cyclic simple shear apparatus. Strain-controlled approach was adopted.

The Influence of Mobility Rate on Spiral Waves in Spatial Rock-Paper-Scissors Games

open access: yesGames, 2016
We consider a two-dimensional model of three species in rock-paper-scissors competition and study the self-organisation of the population into fascinating spiraling patterns.

Dynamical Heterogeneity close to the Jamming Transition in a Sheared Granular Material

open access: yes, 2005
The dynamics of a bi-dimensional dense granular packing under cyclic shear is experimentally investigated close to the jamming transition. Measurement of multi-point correlation functions are produced.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Nonbinary LDPC-Coded Modulation System in High-Speed Mobile Communications

open access: yesIEEE Access, 2018
As a class of capacity-approaching codes, nonbinary low-density parity-check (LDPC) codes have attracted much attention because of noticeable performance.

Effect Of Initial Stress Anisotropy on The Cyclic Behaviour of Sand [PDF]

open access: yesEngineering and Technology Journal, 2005
Due mainly to the process of deposition under earth gravity , the behavior of in situ sand is inherently anisotropic , meaning the stress - strain - strength relations for the same sand may vary as the stress tensor rotates relative to the orientation of

Mobility induces global synchronization of oscillators in periodic extended systems [PDF]

open access: yes, 2010
We study synchronization of locally coupled noisy phase oscillators which move diffusively in a one-dimensional ring. Together with the disordered and the globally synchronized states, the system also exhibits several wave-like states which display local
