Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Pore‐size‐controlled nanoconfinement of rubrene within UiO‐66 and UiO‐67 suppresses aggregation‐caused quenching and restores bright solid‐state emission. Geometric exclusion and energetic destabilization prevent parallel stacking, yielding solution‐like absorption and fluorescence quantum yields up to 25%.

Research on Ultra‐Wideband Pulse Current Method for DC Partial Discharge Measurement
High Voltage, EarlyView.ABSTRACT The conventional pulse current method is commonly used in AC or DC withstand voltage tests with partial discharge (PD) monitoring. Because of its relatively narrow measurement bandwidth, this method tends to ignore critical information in PD waveforms, making it difficult to eliminate pulse‐type interference under DC voltage conditions, where ...

BirdNET: Automated Detection for Monitoring Critically Endangered Lemurs from the Maromizaha Forest
Integrative Zoology, EarlyView.In this study, we evaluated the effectiveness of integrating PAM with BirdNET, a convolutional neural network originally developed for avian vocalization detection, to monitor two critically endangered lemurs, Indri indri and Varecia variegata, in Madagascar's Maromizaha rainforest.

Bandpass filtering in barium titanate
Applied Optics, 1988Real-time spatial filteirng is performed in BaTiO(3) using two different holographic geometries. In both geometries white light images of moderate intensity are used to filter selected portions of Fourier transform holograms written in the crystal. The result is a suppression of certain spatial frequencies in the reconstructed images.

White light images are used to perform real-time spatial filtering in BaTiO3 in two different geometries. White light images act as spatial filters by erasing certain frequency components of photorefractive Fourier transform holograms. As a result, these frequency components are suppressed in the reconstructed holographic images.

Bandpass filtering with lowpass filters
Journal of the Franklin Institute, 1963Abstract Lowpass filters may achieve the effects of bandpass filtering by heterodyning the bandpass wave to obtain the “in-phase” and “quadrature” components and filtering these with suitable lowpass filters. The impulse responses for the lowpass filters are determined in a simple way from the desired bandpass impulse response.

Ultrawideband Balanced Bandpass Filter
IEEE Microwave and Wireless Components Letters, 2011A broadside-coupled structure is utilized to design balanced bandpass filter (BPF) with ultrawideband performance. The top and bottom layers of the structure contain tapered microstrip patches. Those patches are coupled via tapered slots in the ground plane, which is located at the middle layer.

The technique of designing inductorless filters by replacing the inductors in conventional LC filters with gyrators and capacitors is considered for the special case of the high-quality channel bandpass filters used in multiplex telephony. One particular gyrator circuit, which has been found to be very satisfactory, using two operational amplifiers and
