Octave bandwidth photonic fishnet-achromatic-metalens

Nature Communications, 2020
Here the authors demonstrate all-dielectric fishnet-achromatic-metalenses from the visible to the near-infrared region. This metalens performs efficiently independent of polarization over about an octave from 640 nm to 1200 nm.

The oscillatory response of the electroretinogram and neuronal adaptation

Acta Ophthalmologica, EarlyView.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

An extension of the basic local independence model to multiple observed classifications

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The basic local independence model (BLIM) is appropriate in situations where populations do not differ in the probabilities of the knowledge states and the probabilities of careless errors and lucky guesses of the items. In some situations, this is not the case. This work introduces the multiple observed classification local independence model

Hierarchical Differentiable Fluid Simulation

Computer Graphics Forum, EarlyView.
We introduce a two‐step algorithm that significantly reduces memory usage for solving control problems using differentiable fluid simulation techniques: our method first optimizes for bulk forces at reduced resolution, then refines local details over sub‐domains while maintaining differentiability. In trading runtime for memory, it enables optimization

Octave-YOLO: Cross frequency detection network with octave convolution

CoRR
Despite the rapid advancement of object detection algorithms, processing high-resolution images on embedded devices remains a significant challenge. Theoretically, the fully convolutional network architecture used in current real-time object detectors can handle all input resolutions.

Layer3D: A 3D Layered Representation for Multiview Vector Graphics

Computer Graphics Forum, EarlyView.
Abstract We present Layer3D, a novel 3D neural representation that models objects as collections of decomposable neural implicit primitives. These primitives enable the generation of layered images with consistent correspondences across viewpoints, establishing a flexible framework for multiview vector graphics decomposition.

Attenuated selective attention during visual perspective taking in autism: A combined behavior, ERP, and pupillometry study

Journal of Child Psychology and Psychiatry, EarlyView.
Background Altered social cognition in autism may be influenced by difficulties in domain‐general functions, such as selective attention. Here, we manipulated the requirement for selective attention during a visual perspective taking (VPT) task and used neurophysiological indices to delineate underlying mechanisms.

The tympanic covering layer contributes to basilar membrane elasticity potentially influencing human frequency resolution and speech perception

Journal of Anatomy, EarlyView.
In this study we show for the first time that the human basilar membrane contains elastin produced by the so‐called tympanic covering layer. It is believed to play an important functional role in human cochlear tuning, particularly low frequencies linked to our remarkable speech and music perception.

The cochlear morphometry compendium: High‐resolution synchrotron measurements and normative reference values

Journal of Anatomy, EarlyView.
In this study, 100 cadaveric temporal bones underwent synchrotron radiation phase‐contrast imaging. Images were segmented to produce 3D surface mesh models for morphological analysis. Measurements obtained for all cochleae included: standard gross dimensions, various cochlear lengths including basilar membrane length, detailed intracochlear scalar ...
