Rise of the war machines: Charting the evolution of military technologies from the Neolithic to the Industrial Revolution
Plos One. 2021. Vol. 16. No. 10. Article e0258161.
What have been the causes and consequences of technological evolution in world history? In particular, what propels innovation and diffusion of military technologies, details of which are comparatively well preserved and which are often seen as drivers of broad socio-cultural processes? Here we analyze the evolution of key military technologies in a sample of pre-industrial societies world-wide covering almost 10,000 years of history using Seshat: Global History Databank. We empirically test previously speculative theories that proposed world population size, connectivity between geographical areas of innovation and adoption, and critical enabling technological advances, such as iron metallurgy and horse riding, as central drivers of military technological evolution. We find that all of these factors are strong predictors of change in military technology, whereas state-level factors such as polity population, territorial size, or governance sophistication play no major role. We discuss how our approach can be extended to explore technological change more generally, and how our results carry important ramifications for understanding major drivers of evolution of social complexity.

The article analyzes modern legislation regarding artificial termination of pregnancy in countries around the world. Depending on the grounds on which abortion is permitted, five groups of countries are distinguished. Estimates have shown that about 60% of women of reproductive age live in countries with liberal legislation, where abortion is allowed at the request of ...

Malaria control in Malawi relies primarily on long-lasting insecticide-treated nets (LLITNs) and indoor residual spraying (IRS), but transmission remains heterogeneous across districts. Previous research indicates that community-based environmental management strategies, such as routine drainage maintenance, vegetation removal, and effective household waste disposal, may reduce environmental conditions conducive to malaria vector proliferation. This study investigated the ...

The "sweep effect", the most well-known consequence of the multiple non-transferable vote system, is inconsistent. This may be related to the broad voting opportunities provided by the electoral system, which facilitate the formation of diverse voting strategies. In this study, these strategies are classified based on the prevailing models of candidate selection by voters and ...

Automated microscopic image analysis is essential for quantitative microbiology, yet manual acquisition and generic recognition models struggle with morphological variability and scene artifacts. We address both ends of this pipeline. First, we present a low-cost, open-source acquisition system, based on an Arduino UNO R3 microcontroller and NEMA 17 stepper motors, that automates focusing, magnification, and ...

This article explores the role of the term “tolerance” in Russian presidential discourse, 2000-2020. The word became de-politicized (used equally in liberal and in conservative contexts), functioning as a buzzword and as a symbol. As a buzzword, it stood “for all good things” and denoted the positive dynamics in Russia’s nationalities and foreign policies; as ...

In 2006, a “tolerance policy” was launched in St. Petersburg to address the growing xenophobia and the need to integrate labor migrants. Applying a bottom–up perspective, this study finds that this policy was symbolic – aimed at changing public attitudes, not at providing material outcomes. The direct implementers (the street-level bureaucracy), operating under governmental constraints, ...

This article examines the emergence and evolution of revolutionary museology in Imperial Russia between 1901 and 1917, addressing a previously understudied aspect of revolutionary culture. By analysing four successive attempts to establish revolutionary museums – the Russian Museum in Geneva (1901–1902), Maxim Gorky’s initiative on Capri (1912–1913), Vladimir Burtsev’s various projects, and the Petrograd House ...

DreamBooth-style personalization, which often relies on one or a few images, can memorize context (background, pose, lighting) rather than learning the subject’s identity, thereby reducing fidelity and limiting prompt-driven edits. P-LoRA (Probability LoRA) is introduced as a training-time modification that biases diffusion timestep sampling and utilizes importance weights, ensuring that the overall objective remains unchanged. ...

The stability of formal concepts and its generalization as robustness are considered in the paper. We use an approximation of stability in the form of Δ-measure for fast calculations. A computationally efficient method for calculating robustness based on subcontexts is presented. We also present a new method to analytically evaluate the number of preimages for ...

Numerous studies have provided compelling evidence that the probability distribution of avalanche sizes follows a power law, and that 1/f noise is present in the stochastic dynamics of landslides. We present a theoretical explanation of these phenomena within the framework of self-organized criticality theory, proposing a discrete-time model in the form of a sandpile cellular ...

A discrete-time model is presented for the self-organization of the X/Twitter social network to the edge of a phase transition, characterized by avalanche-like propagation of information in the network. The model is based on the analogy between the critical dynamics of the X social network and sandpile cellular automata with Manna rule on the Chung-Lu ...

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

Transformer-based Large Language Models (LLMs) rely on Key-Value (KV) cache to accelerate autoregressive decoding, but memory and compute requirements still grow with context length, limiting deployment on resource-constrained devices. Existing training-free KV cache compression methods mainly rely on attention-driven retention heuristics, which may under preserve structurally informative tokens under tight cache budgets, especially when such ...

For a subfield $\K$ of the field $\C$ of complex numbers, we consider curve and divisorial valuations on the algebra $\K[[x,y]]$ of formal power series in two variables with the coefficients in $\K$. We compute the semigroup Poincar\'e series and the classical Poincar\'e series of a (discrete, rank one) valuation on it. ...

The class of all ∗-continuous Kleene algebras, whose description includes an infinitary condition on the iteration operator, plays an important role in computer science. The complexity of reasoning in such algebras — ranging from the equational theory to the Horn one, with restricted fragments of the latter in between — was analyzed by Kozen (2002). This ...

We show that, in terms of closure ordinals, many infinitary calculi for ‘first-order’ logics of probability (i.e., for languages similar to those in [Abadi & Halpern 1994]) are as hard as possible: the corresponding closure ordinals coincide with the least non-constructive ordinal, denoted by $\omega_1^{\mathrm{CK}}$. ...
