Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation

Advanced Functional Materials, EarlyView.
Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

The Integer Nucleolus of Directed Simple Games: A Characterization and an Algorithm

Games, 2017
We study the class of directed simple games, assuming that only integer solutions are admitted; i.e., the players share a resource that comes in discrete units.

Secret sharing scheme with general access structure based on integer programming [PDF]

Jisuanji gongcheng, 2019
In order to simplify the access structure and ensure that all integer programming have solutions,a scheme is proposed to apply integer programming directly to the secret sharing of general access structure.By constructing integer programming,the secret ...

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

Advanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

On the integer solutions of quadratic equations

Journal für die reine und angewandte Mathematik (Crelles Journal), 2004
The main purpose of the paper is to present an algorithm that decides whether an arbitrary quadratic equation with rational coefficients ( in arbitrarily many unknowns) has a solution in positive integers. The algorithm given is in fact more general, and gives further information: it considers integral solutions restricted to lie in the region bounded ...

Surface Functionalization Modulates Collective Cell Behavior Near Topological Defects Induced by Topographical Patterning

Advanced Materials Interfaces, EarlyView.
Strongly adhered cells align with concentric circular ridges and exhibit predominantly tangential motion, whereas weakly adhered cells fail to follow topographical guidance and display enhanced radial inward motion. ABSTRACT Living cells establish long‐range orientational order through collective alignment, giving rise to topological defects whose ...

Laser‐Induced Local De‐Doping in Organic Semiconductors

Advanced Materials Technologies, EarlyView.
The polymer PBTTT‐C14 doped with the small molecule acceptor F4TCNQ is considered as a benchmark material system. Mask‐free, microscale patterning of the doping level via laser‐induced heating and sublimation of dopant molecules is shown. Controlling laser irradiance and swath spacing allows dopant level control with laser‐limited resolution, opening ...
