Low frequency modulation of jets in quasigeostrophic turbulence

open access: yes, 2016
Quasigeostrophic turbulence on a beta-plane with a finite deformation radius is studied nu- merically, with particular emphasis on frequency and combined wavenumber-frequency do- main analyses.

Weather‐Induced Positive Sentiment and Insider Trading

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT Exploiting variations in sunshine exposure near insiders' locations, we find that weather‐induced positive sentiment leads to higher insider purchases, albeit with lower performance. Overoptimism induced by abnormally good weather serves as the underlying mechanism. The effect is more pronounced when insiders' purchase decisions are fuelled by

Decadal Rapid Change in Energetic Carrying Capacity for Juvenile Chum Salmon in the Sanriku Coast

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Adult returns to coastal rivers in Sanriku, located near the southernmost area of chum salmon distribution, have declined since 2010. Climate‐induced fluctuations in juvenile prey availability may affect growth and survival, which are linked to adult returns.

Update Heat Flow Density Map for Portugal [PDF]

open access: yes, 2010
New thermal conductivity, heat production and temperature data obtained in Portugal were used to produce a new heat flow density map. Heat flow density values in Portugal vary between 42 and 115 mW/m2 and allow the extrapolation of temperatures to depths

Multi‐objective maritime vessel routing with safety considerations

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The routing of maritime vessels is a challenging optimization problem that involves finding an adequate balance between conflicting and multiple objectives. This paper proposes a methodology based on inverse optimization to find appropriate objective weights that account for conflicting objectives. To formulate the inverse optimization problem,

Three Spin Spiky Strings in beta-deformed Background

open access: yes, 2012
We study rigidly rotating strings in $\beta$-deformed $AdS_5\times S^5$ background with one spin along AdS$_5$ and two angular momenta along $S^5$. We find the spiky string solutions and present the dispersion relation among various charges in this ...

Harnessing Human Mobility Data for Applied Economic Research: Current Knowledge, Challenges, and Emerging Opportunities

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT This paper reviews how large‐scale mobility data can enhance economic analyses, highlighting its contributions to understanding travel behavior, labor markets, social interactions, and health outcomes. We discuss its advantages over traditional mobility data sources, which include real‐time location information and fine spatial resolution ...

Adaptive Estimation for Weakly Dependent Functional Times Series

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We propose adaptive mean and autocovariance function estimators for stationary functional time series under 𝕃p−m‐approximability assumptions. These estimators are designed to adapt to the regularity of the curves and to accommodate both sparse and dense data designs.

A Note on Local Polynomial Regression for Time Series in Banach Spaces

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT This work extends local polynomial regression to Banach space‐valued time series for estimating smoothly varying means and their derivatives in non‐stationary data. The asymptotic properties of both the standard and bias‐reduced Jackknife estimators are analyzed under mild moment conditions, establishing their convergence rates.
