Encoding Occupancy in Memory Location for Efficient and Compact High‐Resolution Voxel Structures

open access: yesComputer Graphics Forum, EarlyView.
We encode information about geometric structure into the pointers of a sparse voxel directed acyclic graph (SVDAG). Each pointer carries information about the structure of the node it points to. Our encoding improves ray tracing performance and reduces model size in memory.

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

open access: yesConservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

A link between increased temperature and avian body condition in a logged tropical forest

open access: yesConservation Biology, EarlyView.
Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Implicit Promises and the Timing of Defined‐Benefit Pension Plan Freezes

open access: yesFinancial Management, EarlyView.
ABSTRACT Firms time defined‐benefit (DB) plan freezes after CEO turnovers to protect CEO retirement benefits from cost cuts affecting the wider workforce. We document a significant increase in voluntary CEO turnovers just before the freeze, without notable post‐freeze changes.

An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We study the stability of cryptocurrency systems through difficulty adjustment. Bitcoin's difficulty adjustment algorithm (DAA) exhibits instability when the reward elasticity of the hash rate is high, implying that a sharp price reduction could disrupt the current Bitcoin system.

Cryptocurrency Bubbles and Costly Mining

open access: yesInternational Economic Review, EarlyView.
ABSTRACT This paper develops a model of a cryptocurrency by incorporating mining into the otherwise standard search‐theoretic monetary framework. As usual, multiple equilibria exist. To obtain a sharp prediction on whether a cryptocurrency' s value will last in the future, I propose a notion of equilibrium refinement based on the feature that mining ...

Miners' Reward Elasticity and Stability of Competing Proof‐of‐Work Cryptocurrencies

open access: yesInternational Economic Review, EarlyView.
ABSTRACT Proof‐of‐Work cryptocurrencies employ miners to sustain the system through algorithmic reward adjustments. We develop a stochastic model of the multicurrency mining and identify conditions for stable transaction speeds. Bitcoin's algorithm requires hash supply elasticity <$<$1 for stability, while ASERT remains stable for any elasticity and ...
