eDNA metabarcoding efficiently reveals fish communities across Philippine mangroves, uncovering spatial patterns driven by environmental factors. This powerful approach supports biodiversity conservation, guides fisheries management, and highlights the ecological and economic value of mangrove ecosystems.

Generalized predictive control of nonlinear systems of the Hammerstein form [PDF]
A nonlinear generalized predictive control algorithm based upon a Hammerstein model is presented. Stability of the closed-loop system is analyzed with a control horizon equal to one.

Output Consensus of Networked Hammerstein and Wiener Systems [PDF]
In this paper we consider the output consensus problem of networked Hammerstein and Wiener systems in a noisy environment. The Hammerstein or Wiener system is assumed to be open-loop stable, and its static nonlinearity is allowed to grow up but not faster than a polynomial. A control algorithm based on the distributed stochastic approximation algorithm

Abstract Adolescence is a critical period for developing coping capacities, yet global crises like the COVID‐19 pandemic and war displacement impose unprecedented stressors that can overwhelm existing resources. This study qualitatively explored and compared how adolescents in Germany (N = 20 experiencing pandemic lockdown, aged 11–16; N = 25 Ukrainian

Neural network‐based offset‐free model predictive control for nonlinear systems
Abstract This paper proposes an offset‐free model predictive control (MPC) framework for nonlinear systems modeled using neural network‐based nonlinear autoregressive models with exogenous inputs (NARX). To address plant‐model mismatch and ensure offset‐free tracking, the NARX model is augmented with an integrating disturbance model, resulting in an ...

Initial Undershoot in Discrete-Time Input–Output Hammerstein Systems
This paper considers initial undershoot in the step response of discrete-time, input-output Hammerstein (DIH) systems, which have linear unforced dynamics and nonlinear zero dynamics (ZD).

Abstract Mate value is theorized to be a key driver of romantic partner choice, yet the cognitive mechanism underlying romantic partner choice remains poorly understood. Here, we assess whether initial romantic partner choice can be predicted by a general‐purpose, computational cognitive model of value and choice.

In the in-band full-duplex(FD) systems, the self-interference (SI) power can be more than 100 dB higher than the power of the received data signal. In order to enable the FD transmission, several SI cancelation stages are needed in a FD transceiver.

Abstract We study a nonlinear ψ−$$ \psi - $$ Hilfer fractional‐order delay integro‐differential equation ( ψ−$$ \psi - $$ Hilfer FrODIDE) that incorporates N−$$ N- $$ multiple variable time delays. Utilizing the ψ−$$ \psi - $$ Hilfer fractional derivative ( ψ−$$ \psi - $$ Hilfer‐FrD), we investigate the Ulam–Hyers––Rassias (U–H–R), semi‐Ulam–Hyers ...

Essential dietary fatty acids affect intraspecific competition in herbivorous zooplankton
Abstract The trophic transfer efficiency at the pelagic phytoplankton‐zooplankton interface is—among other factors—governed by the dietary availability of polyunsaturated fatty acids (PUFAs) to herbivorous zooplankton. As most zooplankton taxa cannot synthesize PUFAs de novo, the phytoplankton PUFA composition is crucial for the herbivores' fitness. As
