Advances in Triboelectric Nanogenerators With Rotating Structure
Carbon Energy, EarlyView.The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions
Canadian Journal of Statistics, EarlyView.Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

Neurobiological correlates of obsessive‐compulsive disorder (OCD): A narrative review
Ibrain, EarlyView.Obsessive‐compulsive disorder (OCD) is a common and disabling, as well as underdiagnosed, neuropsychiatric condition characterized by involuntary and unwanted obsessions and/or compulsions often accompanied by states of severe anxiety, distress and shame, as well as other comorbid disorders. Despite the extensive literature available to date, only some

Recursive and Cyclic Constructions for Double‐Change Covering Designs
Journal of Combinatorial Designs, EarlyView.ABSTRACT A double‐change covering design (DCCD) is a v $v$‐set V $V$ and an ordered list L ${\mathscr{L}}$ of b $b$ blocks of size k $k$ where every pair from V $V$ must occur in at least one block and each pair of consecutive blocks differs by exactly two elements. It is minimal if it has the fewest blocks possible and circular when the first and last

JSFA reports, Volume 5, Issue 3, Page 113-124, March 2025.Abstract Background Most pure maple syrup produced in North America is produced from the sap of sugar maple trees (Acer saccharum). Interest is growing to utilize other maple species in different regions of North America outside the native range of sugar maple.

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This paper proposes a novel extension of the classical cobweb price model by incorporating behavioral inventory responses through an anticipatory mini‐storage mechanism. In many real‐world commodity markets, persistent price oscillations occur even when classical stability conditions are theoretically satisfied, an inconsistency traditional ...

Naval Research Logistics (NRL), EarlyView.ABSTRACT This paper examines the impacts of Volume‐Based Procurement (VBP) policies on pharmaceutical supply chains, with a focus on the strategic behaviors of manufacturers. VBP aims to reduce costs and stabilize supplies by centralizing procurement through competition based on volumes and prices.

Finding Maximum Weight 2‐Packing Sets on Arbitrary Graphs
Networks, EarlyView.ABSTRACT A 2‐packing set for an undirected, weighted graph G=(V,E,w)$$ G=\left(V,\kern0.3em E,\kern0.3em w\right) $$ is a subset 𝒮⊆V such that any two vertices v1,v2∈𝒮 are not adjacent and have no common neighbors. The Maximum Weight 2‐Packing Set problem that asks for a 2‐packing set of maximum weight is NP$$ \mathbf{NP} $$‐hard. Next to 13 novel data

The DNA of Calabi–Yau Hypersurfaces
Fortschritte der Physik, EarlyView.Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Journal of Field Robotics, EarlyView.ABSTRACT Planetary exploration is rapidly gaining importance within the space research community. Autonomous locomotion of rovers requires consideration of several mobility aspects to ensure safety, including avoiding hazardous areas that can cause the robot to become immobilized in soft soil or damaged in sharp terrains.
