Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

open access: yesAdvanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...

単葉函数のTaylor係数について

open access: yes, 1967
ある面分Dで一価正則でかつ単葉である函数f(z)については従来多くの結果が得られている。ここではこれ等の結果について初等的に別な角度から少し論究してみることにする。順序として先ず面積定理から初める。(定理)w=f(z)=z+Σ^^∞__(a_n)/(z_n)を∞>|z|>1で正則かつ単葉とするとΣ^^∞__n|a_n|^2≦1(証明)|z|=r(r>1)のw平面への写像の閉曲線をCとし,Cで囲まれた面積をJとすると,w=f(z)=u+ivとおくとJ=∫_cudv今,z=re^とおいて上式を変形するとJ=∫

Dielectric Permittivity Tensor of Muscovite for Next Generation All Van Der Waals Broadband Photonic Components

open access: yesAdvanced Optical Materials, EarlyView.
Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

First observation of Λ+ c → ΛK+ π0 and evidence of Λ+ c → ΛK+ π + π -

open access: yes
We present the first observation of the singly Cabibbo-suppressed decay Lambda thorn c ->Lambda K thorn pi 0with asignificance of5.7 sigma and the first evidence of Lambda thorn c ->Lambda K thorn pi thorn pi-decay with a significance of3.1 sigma,basedone thorn e-annihilation data recorded by the BESIII detector at the BEPCII collider.

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

open access: yesAdvanced Optical Materials, EarlyView.
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

Piezoresistivity Enhancement by Graphite Flake Alignment in Thin Composite Films for Dielectric Elastomer Switches

open access: yesAdvanced Robotics Research, EarlyView.
This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.
