Convexity and translational invariance constraint on the exchange-correlation functional

open access: yes, 1996
Knowledge of the properties of the exchange-correlation functional in the form $\frac 1\lambda v_{xc}([\rho _\lambda ],\frac{{\bf r}}\lambda )$, where $\rho _\lambda ({\bf r})=$ $\lambda ^3\rho (\lambda {\bf r}),$ is important when expressing the ...

Dr. BFS [PDF]

open access: yesProceedings of the 56th Annual Design Automation Conference 2019, 2019
The flexible architectures of Field Programmable Gate Arrays (FPGAs) lend themselves to an array of data analytical applications, among which Breadth-First Search (BFS), due to its vital importance, draws particular attention. Recent attempts that off load BFS on FPGAs either simply imitate the existing CPU-or Graphics Processing Units (GPU)-based ...

Glossiphonia slovaca (Košel 1973) (Hirudinea: Glossiphoniidae) iz Save pri Čatežu: nova vrsta pijavke za Slovenijo in vprašanje njene taksonomske pripadnosti

open access: yesNatura Sloveniae, 2000
Leta 1995 je bil v Savi pri Termah Čatež najden za Slovenijo nov takson pijavke, katerega značilnosti se ujemajo z vrsto Glossiphonia slovaca (Košel 1973). Taksonomija te vrste in njenega sestrskega taksona G.

The distribution of butterflies (Lepidoptera: Rhopalocera) in Haloze, East Slovenia

open access: yesNatura Sloveniae, 2003
Almost nothing has been known about the butterfly fauna of Haloze prior to our survey. During our field trips, including an extensive survey carried within the framework of the Student Research Camp Videm 2002, surprisingly high butterfly diversity was ...

Magnetic explosions: role of the inductive electric field

open access: yes, 2012
Inclusion of the inductive electric field, ${\bf E}_{\rm ind}$ due to the temporally changing ${\bf B}$, in magnetic explosions is discussed, with emphasis on solar flares. Several roles played by ${\bf E}_{\rm ind}$ are identified: on a global scale, ${\

Searching for an algebra on CSP solutions

open access: yes, 2021
The Constraint Satisfaction Problem (CSP) is a problem of computing a homomorphism ${\mathbf R}\to {\bf \Gamma}$ between two relational structures, where ${\mathbf R}$ is defined over a domain $V$ and ${\bf \Gamma}$ is defined over a domain $D$.

Is the anisotropy of the upper critical field of Sr$_2$RuO$_4$ consistent with a helical $p$-wave state?

open access: yes, 2014
We calculate the angular and temperature $T$ dependencies of the upper critical field $H_{c2}(\theta,\phi,T)$ for the $C_{4v}$ point group helical $p$-wave states, assuming a single uniaxial ellipsoidal Fermi surface, Pauli limiting, and strong spin ...

Universal shift register implementation using quantum dot cellular automata

open access: yesAin Shams Engineering Journal, 2018
Quantum-dot Cellular Automata (QCA) demands to be a promising alternative of CMOS in ultra large scale circuit integration. Arithmetic and logic unit designs using QCA are of high research interest. A layout of four and eight bit universal shift register
