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. …

“The EU’s most senior diplomat, Kaja Kallas, said the bloc would keep ‘options on the table’ to pressure Israel’s government if there was no improvement in the ‘catastrophic’ humanitarian situation in Gaza. According to several diplomatic sources she did not endorse any one of 10 sanctions options drawn up by her team, after an earlier EU review found ‘indications’ Israel was in breach of human rights commitments.”

Filmmaker and artist Cauleen Smith on valuing community over status – The Creative Independent
Filmmaker and artist Cauleen Smith discusses the gift of failure, making small moves, and the enduring wisdom of Sun Ra.

For the first time in U.S. history, there are more Americans over 62 than under 18.
With the national workforce getting older every year, many economists argue that having people keep working longer than they used to would help maintain a robust labor market.
But it can be hard for many older adults to stay employed past the age of 62, the year they typically become eligible for early Social Security retirement benefits, even when their health is good.
In part, that’s becaus…

Trump administration ends a federal program helping older people get jobs since the 1960s
The White House left the program out of its proposed 2026 budget due to what it said was a failure at moving older workers into unsubsidized employment.

Galois module structures and the Hasse principle in twist families via the distribution of Selmer groups
We address several seemingly disparate problems in arithmetic geometry: the statistical behaviour of the Galois module structure of Mordell--Weil groups of a fixed elliptic curve over varying quadratic extensions; the frequency of failure of the Hasse principle in quadratic twist families of genus $1$ hyperelliptic curves; and the Hasse principle for Kummer varieties. The common technical ingredient for all of these is a result on the distribution of $2$-Selmer ranks in certain sparse families …

Upcycling solar glass waste to use in solid-state lithium batteries
Nanyang Technological University researchers have milled solar panel glass waste for use in cathodes used in solid state lithium metal batteries. When used as a functional filler in solid polymer electrolyte (SPE) material, the resulting battery performance was maintained over 80 charge cycles with an 8.3 % improvement over the reference device.

EUV Late Phase Flares as Observed by EVE and AIA Onboard the Solar Dynamics Observatory
Context. EUV late phase (ELP) flares exhibit a second peak in warm coronal emissions minutes to hours after the main peak of the flare. This phase is all but negligible, yet it is still poorly understood what role it plays across the solar cycle and what governs it. Aims. We present a statistical analysis of ELP flares over four years between May 2010 and May 2014 based on properties like eruptivity, magnetic configuration, and late-phase duration, delay and strength in order to understand wh…

Hybrid Table-Assisted and RL-Based Dynamic Routing for NGSO Satellite Networks
This letter investigates dynamic routing in Next-Generation Satellite Orbit (NGSO) constellations and proposes a hybrid strategy that combines precomputed routing tables with a Deep Q-Learning (DQL) fallback mechanism. While fully RL-based schemes offer adaptability to topology dynamics, they often suffer from high complexity, long convergence times, and unstable performance under heavy traffic. In contrast, the proposed framework exploits deterministic table lookups under nominal conditions an…
