Analysis of CHIRPS and GPM-IMERG and Discharge Modeling with Transfer Function-GRU in Gembong Watershed, Pasuruan

Jurnal Teknik Pengairan
Rain gauges in Indonesia are often unevenly distributed, with significant gaps in data availability. As an alternative, satellite precipitation products (SPPE), such as CHIRPS and GPM-IMERG, are increasingly used for precipitation estimates. Additionally,

NbN Broadband Plasmonic Absorbers for Efficient Hot‐Carrier Injection Toward Improved Solar‐to‐Hydrogen Conversion

Advanced Science, EarlyView.
Niobium nitride (NbN) broadband plasmonic metasurface absorbers provide an efficient platform for solar‐energy conversion through hot‐carrier injection. Quasi‐epitaxial NbN features a low work function of 4.0 eV, reducing the interfacial injection barrier and facilitating charge transfer into adjacent photocatalysts.

Detection and estimation of generalized chirps using time-frequency representations4

, 1994
We propose techniques for the detection and parameter estimation of generalized chirps in the presence of noise. Generalized chirps are nonstationary signals characterized by group delays with specific dispersion law characteristics.

Phosphine Coordination to Ce, Nd, Np, and Pu in ArBiAMPtBu‐Supported Complexes and Their 2H and 13C Isotopologues

Advanced Science, EarlyView.
A dianionic ligand designed to encourage metal‐phosphine coordination—bis((3,5‐dimethylphenyl)amidomethyl)tertbutylphosphine (ArBiAMPtBu)—was employed in the synthesis of paramagnetic complexes of Ce, Nd, Np, and Pu, producing MI(ArBiAMPtBu)(thf)3.

A Compact and Fast Single‐Spike TTFS Encoder With Ultralow Operating Voltage for Efficient Neuromorphic Fourier Transform

Advanced Science, EarlyView.
A Pt/TaOx/V single‐spike TTFS encoder achieves ultralow‐voltage (∼0.35 V), high‐speed (∼100 ns) operation with simplified circuitry. Integrating bipolar nonuniform temporal encoding with a spiking‐DFT neuron model enables a neuromorphic FFT framework. Device‐calibrated simulations demonstrate high spectral fidelity across multitone, speech, and chirp ...

Validation of new satellite rainfall products over the Upper Blue Nile Basin, Ethiopia [PDF]

Atmospheric Measurement Techniques, 2018
Accurate measurement of rainfall is vital to analyze the spatial and temporal patterns of precipitation at various scales. However, the conventional rain gauge observations in many parts of the world such as Ethiopia are sparse and unevenly ...

Pairing Non‐Fullerene Acceptors With the Right Polymer: Impact of Phase Morphology and Short‐Range Transport on Charge Generation

Advanced Electronic Materials, EarlyView.
This study investigates polymer requirements for pairing with high‐efficiency non‐fullerene acceptors (NFA) in organic photovoltaics by comparing three polymer blends across varied phase morphologies. The generation of free charges is driven by fast transport‐assisted charge separation combined with slow intrinsic recombination.

Interactions of chirped and chirp-free similaritons in optical fiber amplifiers

Nonlinear Optics: Materials, Fundamentals and Applications, 2007
We obtain exact self-similar solutions to an inhomogeneous nonlinear Schrödinger equation, describing propagation of optical pulses in fiber amplifiers with distributed dispersion and gain. We show that there exists a one-to-one correspondence between such self-similar waves and solitons of the standard, homogeneous, nonlinear Schrödinger equation if a
