Multifunctional metaoptics based on bilayer metasurfaces
(Light-Science & Appplications, 2019-09-04)
Optical metasurfaces have become versatile platforms for manipulating the phase, amplitude, and polarization of light. A platform for achieving independent control over each of these properties, however, remains elusive ...
Detecting web attacks with end-to-end deep learning
(Journal of Internet Services and Applications, 2019-08-27)
Web applications are popular targets for cyber-attacks because they are network-accessible and often contain vulnerabilities. An intrusion detection system monitors web applications and issues alerts when an attack attempt ...
Composite Electrode Ink Formulation for All Solid-State Batteries
(Journal of the Electrochemical Society, 2019-09-18)
Solid-state batteries employ composite electrodes which contain a solid ion conductor, a solid active material, a conductive additive, and a binder. The electrode microstructure fundamentally differs from electrodes in ...
Thermal block of action potentials is primarily due to voltage-dependent potassium currents: a modeling study
(Journal of Neural Engineering, 2019-06)
Objective. Thermal block of action potential conduction using infrared lasers is a new modality for manipulating neural activity. It could be used for analysis of the nervous system and for therapeutic applications. We ...
Cold exposure induces dynamic, heterogeneous alterations in human brown adipose tissue lipid content
(Scientific Reports, 2019-09-19)
Brown adipose tissue undergoes a dynamic, heterogeneous response to cold exposure that can include the simultaneous synthesis, uptake, and oxidation of fatty acids. The purpose of this work was to quantify these changes ...
Loss and Damage Estimation for Extreme Weather Events: State of the Practice
(Sustainability, 2019-08)
Extreme weather, climate-induced events that are episodic (e.g., hurricane, heatwave) or chronic (e.g., sea-level rise, temperature change) in nature, is occurring with increasing frequency and severity. This places a ...
Effects of Prolonged Head-Down Bed Rest on Cardiac and Vascular Baroreceptor Modulation and Orthostatic Tolerance in Healthy Individuals
(Frontiers in Pyhsiology, 2019-08-23)
Orthostatic intolerance commonly occurs after prolonged bed rest, thus increasing the risk of syncope and falls. Baroreflex-mediated adjustments of heart rate and sympathetic vasomotor activity (muscle sympathetic nerve ...
Engineered models to parse apart the metastatic cascade
(NPJ Precision Oncology, 2019-08-21)
While considerable progress has been made in studying genetic and cellular aspects of metastasis with in vitro cell culture and in vivo animal models, the driving mechanisms of each step of metastasis are still relatively ...
Electrically defined topological interface states of graphene surface plasmons based on a gate-tunable quantum Bragg grating
(Nanophotonics, 2019-08)
A periodic metagate is designed on top of a boron nitride-graphene heterostructure to modulate the local carrier density distribution on the monolayer graphene. This causes the bandgaps of graphene surface plasmon polaritons ...
Approximate Loop Unrolling
(CF '19 - PROCEEDINGS OF THE 16TH ACM INTERNATIONAL CONFERENCE ON COMPUTING FRONTIERS, 2019-04-30)
We introduce Approximate Unrolling, a compiler loop optimization that reduces execution time and energy consumption, exploiting code regions that can endure some approximation and still produce acceptable results. Specifically, ...
