ABSTRACT Some interaction-powered supernovae have long rise times of more than 100 d. We show that such are naturally expected if cirumstellar matters (CSM) a flat density structure (s ≲ 1.5, where ρCSM∝r−s). In cases, bolometric luminosities from the CSM interaction keep increasing as interacts with outer layers SN ejecta. Thus, time is determined by dynamical time-scale in which reverse shock...

The interaction between nucleotides and carbon nanotubes (CNTs) is a subjectof many investigations for treating diseases but there are many questions in this field thatremain unanswered. Because of experimental methods involve assumptions andinterpretation besides limitations, there are many problems that the best study for them isusing theoretical study. Consequently, t...

the interaction of radiation with cells and tissues has a random nature. therefore, understanding the random nature of cell killing that is determined by poisson distribution statistics is an essential point in education of radiation biology. radbiostat is a newly developed educational matlab-based software designed for computer-assisted learning of the target theory in radiation biology. altho...

The interaction between nanoparticles and biomolecules such as protein andDNA is one of the major instructions of nanobiotechnology research. In this study,we have explored the interaction of adenine nucleic base with a representativegolden cluster (Au13) by using dispersion corrected density functional theory(DFT-D3) within GGA-PBE model of theory. Various active sites ...

This paper presents an efficient optimization procedure to find the optimal shapes of double curvature  arch  dams  considering  fluid–structure  interaction  subject  to  earthquake  loading. The optimization is carried out using a combination of the magnetic charged system search, big bang-big crunch algorithm and artificial neural network methods. Performing the finite element  analysis  dur...

Multi-word expressions (MWEs) are difficult to define and also difficult to annotate. Some of them cause serious errors in the traditional annotation pipeline tokenization – morphological analysis – morphological disambiguation. Many cases of incorrect annotation in Czech corpora are known. To narrow the research topic, we focus only in fixed MWEs – those with fixed word order and no ellidable ...

Identifying whether a multi-word expression (MWE) is compositional or not is important for numerous NLP applications. Sense induction can partition the context of MWEs into semantic uses and therefore aid in deciding compositionality. We propose an unsupervised system to explore this hypothesis on compound nominals, proper names and adjective-noun constructions, and evaluate the contribution of...
