Anisotropic community turn‐over at habitat edges informs on assembly drivers: simulation and empirical test on soil macrofauna

open access: yesOikos, EarlyView.
Biodiversity dynamics in heterogeneous landscapes is the result of a complex interplay between movement processes of organisms within and between habitat patches, and niche filtering processes due to spatially varying environmental conditions. Disentangling the relative influences of these different processes on community assembly and dynamics is a ...

Policy Capacity Under Decentralization: Kindergarten Education Reforms in the Philippines

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT The paper examines the relationship between policy capacity and policy effectiveness in decentralized governance setups. It challenges the conventional view that policy functions should only be decentralized when requisite capacities already exist at lower levels of government. Instead, the paper proposes that capacity can follow function ‐ as

Linear Transformations between Multipartite Quantum Systems That Map the Set of Tensor Product of Idempotent Matrices into Idempotent Matrix Set

open access: yesJournal of Function Spaces and Applications, 2013
Let Hn be the set of n×n complex Hermitian matrices and 𝒫n (resp., 𝒯n) be the set of all idempotent (resp., tripotent) matrices in Hn. In l-partite quantum system Hm1Tml=⊗1lHmi, ⊗1l𝒫mi (resp., ⊗1l𝒯mi) denotes the set of all decomposable elements ⊗1lAi ...

Biomolecular Interaction Prediction in the Pre‐ and Post‐AlphaFold Era: The 8th CAPRI Evaluation

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT We report on the 8th CAPRI Evaluation period, capturing the assessment of CAPRI Rounds 47 to 55 (excluding the CASP and COVID‐related Rounds), which have witnessed the transition to AI‐driven prediction tools such as AlphaFold and related alternatives. The prediction Rounds in this evaluation are characterized by a high level of difficulty due

Multiplicative Perturbations of Convoluted C-Cosine Functions and Convoluted C-Semigroups

open access: yesJournal of Function Spaces and Applications, 2013
We obtain the multiplicative perturbation theorems for convoluted C-cosine functions (resp., convoluted C-semigroups) and n-times integrated C-cosine functions (resp., n-times integrated C-semigroups) for n∈ℕ.

Betulin Protects Against Cardiac Hypertrophy by Improving AMPK/Nrf2‐Dependent Mitochondrial Function

open access: yesPhytotherapy Research, EarlyView.
Betulin effectively mitigates pressure overload‐induced cardiac hypertrophy in both Ang II‐infused and TAC‐operated mice. Mechanistically, betulin activated AMPK phosphorylation, promoted Nrf2 nuclear translocation, and upregulated antioxidant genes (HO‐1 and NQO‐1), thereby restoring mitochondrial function in cardiomyocytes.

Frequency Shaping for Improving a Trade‐Off Between Control and Privacy Performance: Beyond Differential Privacy

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In privacy protection of control systems, a trade‐off between control performance and privacy level is often pointed out. Our goal in this paper is to improve this trade‐off by shaping the frequency of noise added for privacy protection when the control objective is to track a reference signal, which is taken as a piece of information whose ...

Generalizations of Morphic Group Rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
An element a in a ring R is called left morphic if there exists b∈R such that 1R(a)=Rb and 1R(b)=Ra. R is called left morphic if every element of R is left morphic.

Initial State Privacy of Nonlinear Systems on Riemannian Manifolds

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In this paper, we investigate initial state privacy protection for discrete‐time nonlinear closed systems. By capturing Riemannian geometric structures inherent in such privacy challenges, we refine the concept of differential privacy through the introduction of an initial state adjacency set based on Riemannian distances.

When does category spanning hurt or help producers?

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Scholars have theorized many factors shaping whether category spanning helps or hurts producers. We first synthesize evidence by meta‐analyzing 25 years of empirical research, which reveals a null effect of spanning on average, yet with significant subsample heterogeneity. To unpack it, we theorize and find that spanning hurts
