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 ...

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

open access: yesBoreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Authoring Terrestrial Planets with Diffusion Models

open access: yesComputer Graphics Forum, EarlyView.
Abstract To support the design and subsequent generation of terrestrial planets for use in the creative media, we propose a solution that employs a generative model trained on satellite data from planetary bodies with a defined solid surface, such as the Earth and Mars.

Do Banks Learn From Natural Disasters? Evidence From the U.S. Financial Sector

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT This paper examines whether U.S. banks learn from natural disasters. We explore several potential channels of adjustment and find that exposed banks primarily respond by adopting precautionary capital measures. This behaviour is evident both in the long run, when assessing divergent trends in the evolution of equity over time, and in the short

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.

The roles of multinational enterprises in governing the sustainability of global supply chains

open access: yesInternational Journal of Management Reviews, EarlyView.
Abstract An extensive but fragmented body of research shows that multinational enterprises (MNEs) engage with multiple sustainability rules in global supply chains (GSCs) spanning the private, social and public governance sectors. MNEs perform diverse roles by either shaping or complying with these rules.

LAWS simulation: Sampling strategies and wind computation algorithms [PDF]

open access: yes
In general, work has continued on developing and evaluating algorithms designed to manage the Laser Atmospheric Wind Sounder (LAWS) lidar pulses and to compute the horizontal wind vectors from the line-of-sight (LOS) measurements. These efforts fall into
