Revolutionary syndicalism is a radical political and economic ideology that developed in the late 19th century and continued to influence the 20th century. Its central aim was to place political and economic power directly in the hands of the working class through the organized strength of trade unions, rather than through traditional parliamentary or state-centered politics.

I was lucky to get invited on a tour of the University of Coimbra (Portugal) on a recent trip - apparently the 14th oldest university in Europe (1290), and the highlight was definitely the Joanine Library (Biblioteca Joanina). Photography is not permitted in the main library but we were allowed to take snaps in the 19th century vault. A truly remarkable piece of design combining function with beautiful decoration.

Making BERT Feel at Home. Modelling Domestic Space in 19th-Century British and Irish Fiction
We introduce a novel approach to detecting domestic space in literary texts beyond explicit spatial markers like “home” or “house.” Using a pre-trained English BERT model fine-tuned on manually annotated passages from a corpus of 19th-century British and Irish novels, we develop a method to operationalize and quantify domesticity in fiction. Our model captures the nuances of domestic space by analyzing contextual and relational cues rather than relying solely on toponymic and other expl…

Estimation of nanometer-thickness layer of 6B graphite: an experimental activity to study Ohm's law in higher education
Ohm's law is crucial for understanding electrical circuits and conductive materials. Formulated by Georg Simon Ohm in the 19th century, it describes the direct proportional relationship between electric voltage and electric current in ohmic conductors. Despite its apparent simplicity, the literature has pointed out that students at different educational levels have difficulty understanding it, especially due to the abstraction associated with the concepts of electric voltage, electric current, …

Track Component Failure Detection Using Data Analytics over existing STDS Track Circuit data
Track Circuits (TC) are the main signalling devices used to detect the presence of a train on a rail track. It has been used since the 19th century and nowadays there are many types depending on the technology. As a general classification, Track Circuits can be divided into 2 main groups, DC (Direct Current) and AC (Alternating Current) circuits. This work is focused on a particular AC track circuit, called "Smart Train Detection System" (STDS), designed with both high and low-frequency bands. …

Introduction to quantitative De Giorgi methods

Introduction to quantitative De Giorgi methods
The theory of De Giorgi (1958) and Nash (1959) solves Hilbert's 19th problem and constitutes a major advance in the analysis of PDEs in the 20th century. This theory concerns the Hölder regularity of solutions to elliptic and parabolic equations with non-regular coefficients, and it was extended by Moser (1960) to include the Harnack inequality. This course reviews the classical De Giorgi method in the elliptic and parabolic cases and introduces its recent extension to hypoelliptic equations w…

On the finite irreducible subgroups of $\mathrm{GL}_n(\mathbb{C})$ and $\mathrm{PGL}_n(\mathbb{C})$
The classification of the finite subgroups of $\mathrm{GL}_n(\mathbb{C})$ and $\mathrm{PGL}_n(\mathbb{C})$ is a classical problem in the field of finite group theory, dating back to the late 19th century with authors like Klein, Jordan, Blichfeldt, etc. Throughout its long history, many results concerning the classification have been scattered in the mathematical literature. In this survey, we explore many of the most relevant results related to the classification, its structure, and the lists …

Classical Fibonacci compositions

Abstract: There are three long-known types of restricted integer compositions whose counts match the Fibonacci sequence:\ one from ancient India and two from 19th century England. We give proofs of these enumeration results using tiling arguments and discuss how these can be used in combinatorial proofs of several Fibonacci number identities. With MacMahon's notion of conjugation, we show that, for every $n \ge 2$, the compositions of $n$ include subsets whose sizes satisfy the Fibonacci recurrence.

The dawn of alchemical free-energy methods in biomolecular simulations
From the onset of fundamental statistical mechanical constructs formulated in the late 19th century, alchemical free-energy methods slowly emerged and transitioned to become operational tools of biomolecular simulation applicable to a wide range of problems including protein-ligand binding for drug discovery research. This article reconstructs how statistical mechanical approaches such as thermodynamic integration and free-energy perturbation were reconfigured in the early 1980's to address the…
