Tunable plasmon modes and topological transitions in single- and bilayer semi-Dirac materials
We investigate the plasmonic response of single- and bilayer semi-Dirac materials under the influence of a tunable parameter $δ$ that governs topological transitions via Dirac cone generation/merging and incorporating band inversion terms. For single-layer systems, we demonstrate that the emergence of Dirac cones leads to an enhanced plasmon frequency range and that the plasmonic spectrum exhibits strong anisotropy, especially for finite $δ$ and vanishing inversion terms. In the bilayer confi…

A covariant scalar-field framework for singularity resolution and dark energy
We present a covariant scalar-field framework that unifies the space-time singularity resolution with dynamic dark energy. The theory extends general relativity by introducing a scalar field $Φ$ whose potential couples to the Lorentz-invariant quantity $X \equiv u_α u_β T^{αβ}_{\mathrm{matter}}$, ensuring manifest covariance. The resulting density-responsive scalar energy $ρ_Φ$ exhibits dual behavior: (i) in high-density regimes, it saturates at $ρ_Φ\leq AM_P^4/2$, providing a Planck-s…

An 11,000-Study Open-Access Dataset of Longitudinal Magnetic Resonance Images of Brain Metastases
Brain metastases are a common complication of systemic cancer, affecting over 20% of patients with primary malignancies. Longitudinal magnetic resonance imaging (MRI) is essential for diagnosing patients, tracking disease progression, assessing therapeutic response, and guiding treatment selection. However, the manual review of longitudinal imaging is time-intensive, especially for patients with multifocal disease. Artificial intelligence (AI) offers opportunities to streamline image evaluation…

The National Institutes of Health is responsible for more than 80% of the world’s grant investment in biomedical research.
Its funding has sparked countless medical breakthroughs
— on cancer, diabetes, strokes
— and plays a fundamental role in the development of pharmaceutical drugs.
Scientists compete vigorously for a slice of the more than $30 billion that the agency doles out annually;
they can spend years assembling grant applications that stretch thousand…

Science Shattered
The Trump administration cut research funding that sought cures for future pandemics, examined the causes of dementia and tried to prevent HIV transmission. More than 150 researchers shared with ProPublica what is being lost.

Welp I got suspended from Nexdoor for responding to the obvious maga disinformation about No Kings.. Noticed since I still can log in as my other account they did not take down the ones I responded to saying we were being paid to be there and lots of us were going to dress as the other side and make them look like fools per some politician named luna. From a website I would normally not link to but is where most on X facebook and apparently nextdoor are getting their news.

Luna Warns 'Leftists' in MAGA Gear May Disrupt No King's Protests
Congresswoman Anna Paulina Luna issued a warning to the public on Friday, claiming that leftist agitators posing in "MAGA gear" are looking to intentionally s

This grassy field has always been a beautiful buffer between the river and the train tracks that service the local waste management company that owns it. This time of year, wildflowers and butterflies are everywhere and it’s one of the highlights on this part of the greenway.
This week, I’ve noticed it’s suddenly begun to accumulate vintage fire and rescue vehicles. I don’t know what to make of it, but I hope it’s temporary.

NATO-Chef dringt auf höhere Militärausgaben
NATO-Generalsekretär Mark Rutte mahnt angesichts der geopolitischen Konfrontation mit Russland zu deutlich höheren Verteidigungsausgaben. "Wir müssen bereit sein", sagte er bei einem Besuch in Litauen. Der jetzige Zielwert der Militärallianz reiche bei weitem nicht aus. Auch der Gastgeber, Litauens Präsident Gitanas Nauseda, rief die Verbündeten dazu auf, deutlich mehr Geld ins Mili…

Ukraine-Liveblog: ++ Wadephul: Müssen Druck aufrechterhalten ++
Bundesaußenminister Wadephul hat nach einem Treffen mit US-Senator Graham eine gemeinsame harte Linie gegenüber Russlands Präsidenten Putin betont. Friedensforscher mahnen eine Verteidigungsstrategie für Europa an.

Marines are highly trained in combat and crisis response, with time in conflict zones like Syria and Afghanistan.
But that is starkly different from the role they will face now:
They could potentially be hit by L A hipsters carrying gas canisters and have to quickly decide how to respond
or face decisions about protecting an immigration enforcement agent from crowds.

Pentagon draws up rules for Marines deployed to LA protests
The Pentagon is scrambling to establish rules to guide U.S. Marines who could be faced with the rare and difficult prospect of using force against citizens on American soil, now that the Trump administration is deploying active duty troops to the immigration raid protests in Los Angeles. U.S. Northern Command said Monday that it's sending 700 Marines into the Los Angeles area to protect federal property and personnel. A U.S. official says troops will be armed with their normal service weapons b…

LinGuinE: Longitudinal Guidance Estimation for Volumetric Lung Tumour Segmentation
Segmentation of lung gross tumour volumes is an important first step in radiotherapy and surgical intervention, and is starting to play a role in assessing chemotherapy response. Response to a drug is measured by tracking the tumour volumes over a series of CT scans over a time period i.e. a longitudinal study. However, there currently exist few solutions for automated or semi-automated longitudinal tumour segmentation. This paper introduces LinGuinE, an automated method to segment a longitudin…

Generalinspekteur verteidigt geplante Militärausgaben
Der Generalinspekteur der Bundeswehr, Carsten Breuer, hat deutlich steigende Verteidigungsausgaben gerechtfertigt. Die diskutierten Ausgaben in Höhe von 3,5 Prozent des Bruttoinlandsprodukts seien nicht aus der Luft gegriffen, sagte der ranghöchste Soldat der Bundeswehr dem Spiegel. "Sie sind klar abgeleitet aus einer deutlichen Bedrohung durch Russland. Gegen diese Gefahr…
