Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

, 2012 The primordial curvature perturbation zeta may be generated by some curvaton field sigma, which is negligible during inflation and has more or less negligible interactions until it decays.

More on the Non-Gaussianity of Perturbations in a Nonminimal Inflationary Model
Advances in High Energy Physics, 2018 We study nonlinear cosmological perturbations and their possible non-Gaussian character in an extended nonminimal inflation where gravity is coupled nonminimally to both the scalar field and its derivatives.

Examining Non-Gaussianities in 1+1 Dimensions [PDF]
openThis thesis focuses broadly on how to measure Non-Gaussianity, the deviation of perturbations from statistical Gaussianity. Observationally constraining Primordial Non-Gaussianity (PNG) in galaxy surveys will help elucidate the physics of the early ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer
Advanced Functional Materials, EarlyView.Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Non-Gaussianity from the inflationary trispectrum
, 2007 We present an estimate for the non-linear parameter tau(NL), which measures the non-Gaussianity imprinted in the trispectrum of the comoving curvature perturbation, zeta.

Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Integration of Low‐Voltage Nanoscale MoS2 Memristors on CMOS Microchips
Advanced Functional Materials, EarlyView.This article presents the first monolithic integration of nanoscale MoS2‐based memristors into the back‐end‐of‐line of foundry‐fabricated CMOS microchips in a one‐transistor‐one‐resistor (1T1R) architecture. The MoS2‐based 1T1R cells exhibit forming‐free, nonvolatile resistive switching with ultra‐low operating voltages, low cycle‐to‐cycle variability ...

Non-Gaussianity from Particle Production during Inflation
Advances in Astronomy, 2010 In a variety of models the motion of the inflaton may trigger the production of some non-inflaton particles during inflation, for example via parametric resonance or a phase transition.
