The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?
Marine Ecology, EarlyView.ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Single-Stage Double-Buck Topologies with High Power Factor [PDF]
Journal of Power Electronics, 2011 This paper presents two topologies for single-stage single-phase double-buck type PFC converters, designed to operate at high power factor, near sinusoidal input currents and adjustable output voltage. Unlike the known buck type PFC topologies, in which the output voltage is always lower than the maximum input voltage, the proposed converters can ...

Mathematical Finance, EarlyView.ABSTRACT We study a dynamic portfolio optimization problem under the mean–variance–variance (M‐V‐V) criterion proposed by Maccheroni et al. It is an analogue of the Arrow–Pratt approximation to the well‐known smooth ambiguity model. Under the standard Black–Scholes framework, we derive fully explicit equilibrium investment strategies in which a DM's ...

Inference on the Attractor Space via Functional Approximation
Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 643-657, August 2026.ABSTRACT This paper discusses semiparametric inference on hypotheses on the cointegration and the attractor spaces for I(1) linear processes with moderately large cross‐sectional dimension. The approach is based on sample canonical correlations and functional approximation of Brownian motions, and it can be applied both to the whole system and or to ...

Time-sharing power supply full-bridge buck mode dual-input DC-DC converter
Dianzi Jishu Yingyong, 2020 In the distributed generation system with multiple new energy joint supply, using a multi-input DC-DC converter instead of multiple single input DC-DC converters can simplify the circuit structure and reduce the cost.

Population Ecology, Volume 68, Issue 3, July 2026.We removed the most critical connection(s) of experimental habitat networks inhabited by Daphnia carinata to completely separate them into two sub‐networks. The results showed reduced population size and stability across different topologies after the loss of connectivity.

Eletrônica de Potência, 2019 This paper introduces a new family of nonisolated dc-dc converters that are generated by the integration of the active switched-capacitor (ASCC) and the conventional commutation cell (CCC). Based on the commutation cell concept, the new conceived hybrid

An Optimal Edge Data Caching Scheme Based on Improved Particle Swarm Optimization
Concurrency and Computation: Practice and Experience, Volume 38, Issue 13, July 2026.ABSTRACT Mobile Edge Computing (MEC) alleviates the performance bottlenecks of traditional cloud computing in latency‐sensitive scenarios by moving computational resources to network edge nodes. In recent years, numerous research efforts have focused on developing edge data caching (EDC) strategies that enable app vendors to enhance caching performance

Impact of QSW‐ZVS on Input EMI Filter Design in DC‐DC Converters
International Journal of Circuit Theory and Applications, Volume 54, Issue 7, Page 3545-3554, July 2026.This paper analyzes the impact of quasi‐square wave zero voltage switching (QSW‐ZVS) on passive EMI filter design for DC‐DC buck converters. The extra element theorem (EET) is used to derive the design quantities that ensure converter performance is not altered, and the resulting damping element values are compared with those of traditional converters.
