Highly accurate machine learning prediction of crystal point groups for ternary materials from chemical formula

open access: yesScientific Reports, 2022
One of the most challenging problems in condensed matter physics is to predict crystal structure just from the chemical formula of the material. In this work, we present a robust machine learning (ML) predictor for the crystal point group of ternary ...

Multicomponent Solar Cells with High Fill Factors and Efficiencies Based on Non-Fullerene Acceptor Isomers

open access: yesMolecules, 2022
Multicomponent organic solar cells (OSCs), such as the ternary and quaternary OSCs, not only inherit the simplicity of binary OSCs but further promote light harvesting and power conversion efficiency (PCE).

Role of ternary hybrid nanofluid in the thermal distribution of a dovetail fin with the internal generation of heat

open access: yesCase Studies in Thermal Engineering, 2022
The primary goal of this research is to examine the thermal variance in a dovetail fin under fully wet conditions with ternary hybrid nanofluid ZnFe2O4 +MnZnFe2O4 +NiZnFe2O4- H2O taking temperature and humidity ratio differences into account as driving ...

Enumeration of balanced ternary designs

open access: yesDiscrete Applied Mathematics, 2004
A \((V,B; \rho_1,\rho_2, R; K,\Lambda)\) balanced ternary design consists of a pair \(({\mathcal V}, {\mathcal B})\), where \({\mathcal V}\) is a \(V\)-set of points and \({\mathcal B}\) is a collection of \(B\) \(K\)-multisubsets of \({\mathcal V}\), called blocks, such that each point appears a total of \(R\) times in the blocks with no block ...

Schaefer's theorem for graphs [PDF]

open access: yes, 2015
Schaefer's theorem is a complexity classification result for so-called Boolean constraint satisfaction problems: it states that every Boolean constraint satisfaction problem is either contained in one out of six classes and can be solved in polynomial ...

Ternary All-Polymer Solar Cells With 8.5% Power Conversion Efficiency and Excellent Thermal Stability

open access: yesFrontiers in Chemistry, 2020
All-polymer solar cells (all-PSCs) composed of polymer donors and acceptors have attracted widespread attention in recent years. However, the broad and efficient photon utilization of polymer:polymer blend films remains challenging. In our previous work,

Arithmetic with binary-encoded balanced ternary numbers [PDF]

open access: yes2013 Asilomar Conference on Signals, Systems and Computers, 2013
Ternary number representation and arithmetic, based on the radix-3 digit set {-1, 0, ;1}, has been studied at various times in the history of digital computing. Some such studies concluded that we should abandon ternary in favor of binary computation.

Stability of bicontinuous cubic phases in ternary amphiphilic systems with spontaneous curvature [PDF]

open access: yes, 1999
We study the phase behavior of ternary amphiphilic systems in the framework of a curvature model with non-vanishing spontaneous curvature. The amphiphilic monolayers can arrange in different ways to form micellar, hexagonal, lamellar and various ...

Epitaxial designs for maximizing efficiency in resonant tunnelling diode based terahertz emitters [PDF]

open access: yes, 2018
We discuss the modelling of high current density InGaAs/AlAs/InP resonant tunneling diodes to maximize their efficiency as THz emitters. A figure of merit which contributes to the wall plug efficiency, the intrinsic resonator efficiency, is used for the ...

Constructions of balanced ternary designs [PDF]

open access: yesJournal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1990
AbstractA construction for balanced ternary designs is given. Based on the designs so obtained, a construction of partially balanced ternary designs is given, which gives balanced ternary designs and series of symmetric balanced ternary designs in special cases.
