Fused Collapsing for Wide BVH Construction

Computer Graphics Forum, EarlyView.
Abstract We propose a novel approach for constructing wide bounding volume hierarchies on the GPU by integrating a simple bottom‐up collapsing procedure within an existing binary bottom‐up BVH builder. Our approach directly constructs a wide BVH without traversing a temporary binary BVH as done by previous approaches and achieves 1.4 – 1.6 × lower ...

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

Computer 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.

Miss-Triggered Content Cache Replacement Under Partial Observability: Transformer-Decoder Q-Learning

Mathematics
Content delivery networks (CDNs) face steadily rising, uneven demand, straining heuristic cache replacement. Reinforcement learning (RL) is promising, but most work assumes a fully observable Markov Decision Process (MDP), unrealistic under delayed ...

0.001% and counting: Revisiting the price rounding tax

Contemporary Economic Policy, EarlyView.
Abstract In 1991 and 2008, Israel abolished the equivalents of 1¢ and 5¢ coins, respectively, effectively eliminating low‐denomination coins and introducing rounding in cash transactions. When totals were rounded up, shoppers incurred a small rounding tax.

China inside out: Explaining silver flows in the triangular trade, c. 1820s‒70s

The Economic History Review, EarlyView.
Abstract This paper analyses a new large dataset of silver prices, as well as silver and merchandise trade flows in and out of China in the crucial decades of the mid‐nineteenth century when the Empire was opened to world trade. Silver flows were associated with the interaction between heterogeneous monetary preferences and availability of specific ...

Between famine and freedom: Food prices during the Indonesian War of Independence, 1945–9

The Economic History Review, EarlyView.
Abstract This paper investigates how the Indonesian War of Independence (1945‒9) influenced staple food prices, and how fluctuations in those prices, in turn, shaped the trajectory and dynamics of the conflict. We compiled a dataset comprising more than 8600 prices for staple foods covering the entire Indonesian archipelago from 1939‒49, allowing us to
