On the expressiveness of spider diagrams and commutative star-free regular languages [PDF]

open access: yes, 2013
Spider diagrams provide a visual logic to express relations between sets and their elements, extending the expressiveness of Venn diagrams. Sound and complete inference systems for spider diagrams have been developed and it is known that they are ...

Regulating Autonomous Weapon Systems: Searching for African Solutions to Regional and Global Problems

open access: yesRegulation &Governance, EarlyView.
ABSTRACT Lethal autonomous weapon systems (LAWS), while offering strategic advantages in warfare, pose significant ethical, legal, and security risks, especially for countries in the Global South. This article examines how a philosophical perspective, rooted in African ethical and political thought, can enrich regional and global debates on regulating ...

Highlights in the knowledge of brown spider toxins

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2017
Brown spiders are venomous arthropods that use their venom for predation and defense. In humans, bites of these animals provoke injuries including dermonecrosis with gravitational spread of lesions, hematological abnormalities and impaired renal function.

Obesity and the Politics of Taddeo di Bartolo's Inferno

open access: yesRenaissance Studies, EarlyView.
ABSTRACT This paper examines Taddeo di Bartolo's depiction of Hell in the Collegiata di Santa Maria Assunta, the mother church of San Gimignano. In a striking departure from similar scenes of the period, the fresco, painted in the early fifteenth century, emphasizes the obesity of the sinners—suggesting a deliberate visual critique.

Gut Microbiome Diversity, Functional Potential, and Ecological Relevance of Hottentotta tamulus

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
Long‐read 16S sequencing uncovers the gut microbiome of H. tamulus. A highly conserved and low‐diversity bacterial community dominates the gut fauna. Bacillus and Mycoplasma lineages emerge as predominant candidate endosymbionts. Exploratory profiles reveal potential sex‐specific trends in microbial abundance.

What Can Spider Diagrams Say? [PDF]

open access: yes, 2004
Spider diagrams are a visual notation for expressing logical statements. In this paper we identify a well known fragment of first order predicate logic, that we call ESD, equivalent in expressive power to the spider diagram language.

Darwin's Naturalization Conundrum in the Azores: Scale‐Dependent Patterns of Arthropod Invasion

open access: yesDiversity and Distributions, Volume 32, Issue 10, October 2026.
ABSTRACT Aim To test the mechanisms governing the assembly of exotic arthropods within endemic‐rich island communities by evaluating Darwin's naturalization conundrum, which predicts that invasion success occurs through either functional dissimilarity from native species (Naturalization Hypothesis) or functional similarity with them (Pre‐adaptation ...

The Dual Prey-Inactivation Strategy of Spiders—In-Depth Venomic Analysis of Cupiennius salei

open access: yesToxins, 2019
Most knowledge of spider venom concerns neurotoxins acting on ion channels, whereas proteins and their significance for the envenomation process are neglected.

Persistence without prosperity at the upper range margin: Elevation, microhabitat buffering and biotic pressure in a range‐expanding spider

open access: yesEcological Entomology, Volume 51, Issue 5, Page 926-943, October 2026.
Anthropogenic linear features facilitate high‐elevation colonization. Parasitoid pressure declines markedly with elevation. Cocoon damage increases despite reduced parasitism at high elevation. Abstract The upper elevational range limits of thermophilic arthropods reflect constraints on population persistence rather than simple presence.
