Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

Advanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

MIMO-OFDM System Performance and Parameter Estimations in Presence of Design Imperfections

IEEE Access
Most of the MIMO-OFDM analyses in the literature assume idealized receiver conditions in terms of time and frequency synchronization, and sampling clock offset.

Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Grayscale Photomasks Enable Noncontact Optical Patterning of Hydroxypropyl Cellulose Gels for Dynamic Art

Advanced Functional Materials, EarlyView.
Mask‐encoded UV exposure translates digital color information into pixel‐resolved structural‐color patterns in hydroxypropyl cellulose gels. Gaussian‐process‐guided calibration links UV processing conditions, wavelength, and mask opacity, enabling parallel fabrication of multicolor images in a single 10 s exposure.

Quantifying the improvement of MMSE equalizers by faster sampling rates

, 2017
The efficiency of faster than symbol rate sampled MMSE equalizers, which is generally considered as a remedy to time or phase errors, is explicitly analyzed accounting for practical channel conditions and pulse shaping filter.

Learning Rate Updating Methods Applied to Adaptive Fuzzy Equalizers for Broadband Power Line Communications

EURASIP Journal on Advances in Signal Processing, 2004
This paper introduces adaptive fuzzy equalizers with variable step size for broadband power line (PL) communications. Based on delta-bar-delta and local Lipschitz estimation updating rules, feedforward, and decision feedback approaches, we propose ...

Ligand Assisted Epitaxial Growth of CsPbBr3 Microcrystal Resonators With Record ‐Low Lasing Thresholds

Advanced Functional Materials, EarlyView.
Solution‐based ligand‐assisted epitaxial growth (LAEG) yields high‐quality CsPbBr3 microcrystals on different substrates with superior morphology, passivated surfaces, and high photoluminescence quantum yield. These robust micro‐resonators achieve record‐low room‐temperature lasing thresholds of 7.2 kW·cm−2 and maintain operational stability up to 90 ...

Importance sampling simulation for evaluating the lower-bound BER of the Bayesian DFE

, 2002
We extend the importance sampling (IS) simulation technique of Iltis, originally derived for Bayesian equalizers, to evaluate the lower-bound bit error rate (BER) of the Bayesian decision feedback equalizer (DFE) under the assumption of correct decisions

Equality of Opportunity and Equality of Outcome

Center for Educational Policy Studies Journal, 2016
The report on the findings of extensive empirical research on equality of educational opportunities carried out in the US on a very large sample of public schools by Coleman and his colleagues has had a major impact on education policy and has given rise to a large amount of research and various interpretations.

Triangle equalizers - a probabilistic approach, part 1 [PDF]

, 2016
An equalizer of a triangle is a line which divides it into two regions having equal areas as well as equal perimeters. Every triangle has at least one and at most three equalizers.
