Pressure Raman effects and internal stress in network glasses [PDF]

open access: yes, 2005
Raman scattering from binary GexSe1-x glasses under hydrostatic pressure shows onset of a steady increase in the frequency of modes of corner-sharing GeSe4 tetrahedral units when the external pressure P exceeds a threshold value Pc.

Metallic nanocrystals with low angle grain boundary for controllable plastic reversibility

open access: yesNature Communications, 2020
Advanced nanodevices require reliable nanocomponents where mechanically-induced irreversible structural damage should be largely prevented. However, a practical methodology to improve the plastic reversibility of nanosized metals remains challenging ...

Design and evaluation of practice-oriented materials fostering students’ development of problem-solving competence

open access: yesLUMAT, 2019
In a design-research project on problem-solving, theory-based and practice-oriented materials were developed with the goal of fostering systematical development of students’ problem-solving competence in a targeted manner by learning heuristics.

Non-Reversibility of Molecular Dynamics Trajectories [PDF]

open access: yes, 1996
We study the non-reversibility of molecular dynamics trajectories arising from the amplification of rounding errors. We analyse the causes of such behaviour and give arguments, indicating that this does not pose a significant problem for Hybrid Monte ...

Finding complex balanced and detailed balanced realizations of chemical reaction networks [PDF]

open access: yes, 2010
Reversibility, weak reversibility and deficiency, detailed and complex balancing are generally not "encoded" in the kinetic differential equations but they are realization properties that may imply local or even global asymptotic stability of the ...

Review of SERS Substrates for Chemical Sensing

open access: yesNanomaterials, 2017
The SERS effect was initially discovered in the 1970s. Early research focused on understanding the phenomenon and increasing enhancement to achieve single molecule detection. From the mid-1980s to early 1990s, research started to move away from obtaining

Some Liouville Theorems on Finsler Manifolds

open access: yesMathematics, 2019
We give some Liouville type theorems of L p harmonic (resp. subharmonic, superharmonic) functions on a complete noncompact Finsler manifold.

Microscopic analysis of the microscopic reversibility in quantum systems

open access: yes, 2011
We investigate the robustness of the microscopic reversibility in open quantum systems which is discussed by Monnai [arXiv:1106.1982 (2011)]. We derive an exact relation between the forward transition probability and the reversed transition probability ...

Significance of Eradication on Atrophic Gastritis and Intestinal Metaplasia [PDF]

open access: yesThe Korean Journal of Helicobacter and Upper Gastrointestinal Research, 2020
There has been an accumulation of data regarding the chemopreventive effects of Helicobacter pylori (H. pylori) eradication. However, it remains unclear how H. pylori infection causes gastric cancer (GC) and how H.
