Edge Sharpness Does Not Vary Between Palaeolithic Flake Technologies, With the Possible Exception of Levallois Débitage

open access: yesArchaeometry, EarlyView.
ABSTRACT Investigating why hominins adopted particular flake technologies during the Mid‐to‐Late Pleistocene is essential to understanding patterns of lithic innovation. This period witnessed the emergence of Levallois technologies (~350–250 ka) and later blades, each “replacing” earlier forms.

Lattice Points in Large Borel Sets and Successive Minima

open access: yes, 2005
Let $B$ be a Borel set in $\mathbb E^{d}$ with volume $V(B)=\infty$. It is shown that almost all lattices $L$ in $\mathbb E^{d}$ contain infinitely many pairwise disjoint $d$-tuples, that is sets of $d$ linearly independent points in $B$.

What Do Lithics Tell Us About Cultural Evolution? Insights From the Central African Record

open access: yesArchaeometry, Volume 68, Issue S3, Page S40-S49, June 2026.
ABSTRACT While Western historical narratives often incorporate a biased vision of human evolution—driven by a progressive view tied to a progressively evolving state of culture—this paper proposes combining archaeological lithic data with epistemological reflections to critique the modern regime of historicity, where progress is assumed as rational ...

SDFs from Unoriented Point Clouds using Neural Variational Heat Distances

open access: yesComputer Graphics Forum, EarlyView.
We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from unoriented point clouds. We first compute a small time step of heat flow (middle) and then use its gradient directions to solve for a neural SDF (right). Abstract We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from ...

Borel type asymptotic relation for entire Dirichlet series and $h$-measure of an exceptional sets

open access: yesМатематичні Студії
There are presented sufficient conditions for the entire Dirichlet series with monotonically increasing  sequence of exponents providing validity of Borel-type relation outside some set $E$ of finite $h$-measure, i.e. $m_h E=\int_E dh(x)

Medical Knowledge Integration Into Reinforcement Learning Algorithms for Dynamic Treatment Regimes

open access: yesInternational Statistical Review, EarlyView.
Summary The goal of precision medicine is to provide individualised treatment at each stage of chronic diseases, a concept formalised by dynamic treatment regimes (DTR). These regimes adapt treatment strategies based on decision rules learned from clinical data to enhance therapeutic effectiveness.

On Spatial Point Processes With Composition‐Valued Marks

open access: yesInternational Statistical Review, EarlyView.
Summary Methods for marked spatial point processes with scalar marks have seen extensive development in recent years. While the impressive progress in data collection and storage capacities has yielded an immense increase in spatial point process data with highly challenging non‐scalar marks, methods for their analysis are not equally well developed ...

Structure of the isotropic transport operators in three independent space variables [PDF]

open access: yes, 1969
Based on the idea of separation of variables, a spectral theory for the three-dimensional, stationary, isotropic transport operator in a vector space of complex-valued Borel functions results in continuous sets of regular and generalized ...

A note on generalised information criteria for structured sparse models

open access: yesInternational Statistical Review, EarlyView.
Summary We propose a generalised information criteria ( gic) that accounts for sparsity pattern in the model. We obtain both asymptotic and nonasymptotic results for model selection. Moreover, we show that the gic is useful for selecting the regularisation parameter in regularised m$$ m $$ estimation in high‐dimensional scenarios.
