We trace with high numerical accuracy the phase diagram of the Gaussian-core model, a classical system of point particles interacting via a Gaussian-shaped, purely repulsive potential. This model, which provides a reliable qualitative description of the thermal behavior of interpenetrable globular polymers, is known to exhibit a polymorphic fcc-bcc transition at low densities and reentrant melt...

Studies have investigated the relationship between XPD Lys751Gln and Asp312Asn genetic variants and risk of cutaneous basal cell carcinoma (BCC). However, the results remain inconclusive. We performed a meta-analysis, using a comprehensive strategy based on the allele model and a model-free approach, to investigate the association of between XPD Lys751Gln and Asp312Asn polymorphisms with BCC ri...

Super-efficiency data envelopment analysis (DEA) model is obtained when a decision making unit (DMU) under evaluation is excluded from the reference set. Because of the possible infeasibility of super-efficiency DEA model, the use of super-efficiency DEA model has been restricted to the situations where constant returns to scale (CRS) are assumed. It is shown that one of the input-oriented and ...

Basal cell carcinoma (BCC) belongs to the group of non-melanoma skin tumors and is the most common tumor in the western world. BCC arises due to mutations in the tumor suppressor gene Patched1 (Ptch). Analysis of the conditional Ptch knockout mouse model for BCC reveals that macrophages and dendritic cells (DC) of the skin play an important role in BCC growth restraining processes. This is base...

Data Envelopment Analysis (DEA) deals with evaluating a set of decision-making units (DMUs) based on nonparametric mathematical approaches. In classical DEA models, the given set of factors of DMUs is divided into two categories, inputs and outputs, while in some practical problems there are some measures whose membership to these categories is unclear. It means these factors treat different in...

The study of various countries rail transportation indicators is an appropriate criterion for evaluating the existing performance of Iranian railways. The experiences of other countries can be used to improve the efficiency of Iran’s rail transportation. At the beginning of the study, in order to compare the Iranian railway performance with railways of other countries, various efficiency indica...

The notion of pseudo-valuations (valuations) on a BCC-algebra is introduced by using the Buşneag’s model ([1–3]), and a pseudo-metric is induced by a pseudo-valuation on BCC-algebras. Conditions for a real-valued function to be an BCK-pseudo-valuation are provided. The fact that the binary operation in BCC-algebras is uniformly continuous is provided based on the notion of (pseudo) valuation.

A Monte Carlo simulation study is made of the phase diagram of the restricted primitive model and of the solid± liquid and solid± solid phase coexistence curves in particular. At low temperatures, there is liquid± bcc coexistence and with increasing density there is bcc± fcc coexistence. These coexistence curves end in a triple point (liquid± bcc ± fcc) above which only liquid± fcc coexistence ...

E-Government is one area of digitization that has been under way for several years in European countries. In this paper, we focus on identifying different indices are aimed at measuring digitalization or e-Government. The results the analysis showed there within EU, such as EGDI, EPI, LOSI, DGI, e-Government benchmark, Eurostat—Internet use, GII, DSGI, Going Digital toolkit, and DESI. Subsequen...
