Effective Hamiltonian for surface states of \ce{Bi2Te3} nanocylinders with hexagonal warping
, 2016 The three-dimensional topological insulator \ce{Bi2Te3} differs from other topological insulators in the \ce{Bi2Se3} family in that the effective Hamiltonian of its surface states on a flat semi-infinite slab requires the addition of a cubic momentum ...

The warping matrix of a knot diagram [PDF]
arXiv, 2015 We introduce the warping matrix which is a new description of oriented knots from a viewpoint of warping degree.

Advanced Materials Technologies, EarlyView.This study examines a soft gripper with a NiTiCu6 Shape Memory Alloy (SMA) wire embedded in a graphene nanoparticle (GNP)‐functionalized PDMS matrix. Comparing GNP‐enhanced and plain elastomer prototypes, results show that GNPs improve cooling rates, accelerating release by 40%, but increase energy consumption in low‐current activations.

Transverse shear warping functions for anisotropic multilayered plates
, 2012 In this work, transverse shear warping functions for an equivalent single layer plate model are formulated from a variational approach. The part of the strain energy which involves the shear phenomenon is expressed in function of the warping functions ...

Dielectric Barrier Discharge Electrothermal Heating and Additive Manufacturing of Thermoset Parts
Advanced Materials Technologies, EarlyView.3D printing of thermosets is difficult due to the low yield stress of most uncured resins. However, by locally heating resin using a non‐equilibrium plasma, layers can be partially cured and printing enabled. Plasma application to a liquid epoxy/carbon nanotube composite is observed to cause rapid surface heating and oxidation of the cured layers ...

CIAO: Cache Interference-Aware Throughput-Oriented Architecture and Scheduling for GPUs [PDF]
arXiv, 2018 A modern GPU aims to simultaneously execute more warps for higher Thread-Level Parallelism (TLP) and performance. When generating many memory requests, however, warps contend for limited cache space and thrash cache, which in turn severely degrades performance.

Dual‐Wavelength Vat Photopolymerization With Dissolvable, Recyclable Support Structures
Advanced Materials Technologies, EarlyView.Selective solubility vat photopolymerization (SSVP) uses a single resin to produce dissolvable thermoplastics and insoluble thermosets in a single 3D print. Wavelength‐selective curing and thermal post‐processing provide 3D spatial control over dissolution kinetics, enabling dissolvable support structures and programmable dissolution profiles.

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%
Advanced Robotics Research, EarlyView.Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

Relationship between cooling parameters and warping of hot rolled strips
工程科学学报, 2016 For 12-ram-thick hot-rolled X70 pipeline steel strips coiled at 500 ℃, a coupled thermomechanicalphase transition model in the laminar cooling process was established by MARC finite element software, and then the changes in temperature field, stress ...
