DEI, antisemitism, and transgender athletes are not the real reasons for these attacks on higher education. They’re excuses to give the Trump regime power over America’s colleges and universities.
Why do Trump and his lackeys want this power?
They’re following Hungarian president Viktor Orbšn’s playbook for creating an “illiberal democracy”
– an authoritarian state masquerading as a democracy. The playbook goes like this:
First, take over military and intelligence ope…

Implantation studies of low-energy positive muons in niobium thin films
Here we study the range of keV positive muons $μ^+$ implanted in Nb$_2$O$_5$($x$ nm)/Nb($y$ nm)/SiO$_2$(300 nm)/Si [$x$ = 3.6 nm, 3.3 nm; $y$ = 42.0 nm, 60.1 nm] thin films using low-energy muon spin spectroscopy (LE-$μ$SR). At implantation energies 1.3 keV $\leq E \leq$ 23.3 keV, we compare the measured diamagnetic $μ^+$ signal fraction $f_{\mathrm{dia.}}$ against predictions derived from implantation profile simulations using the TRIM.SP Monte Carlo code. Treating the implanted $μ^+$ as l…

The fediverse is often full of drama with admins falling out with each other and defederations, and threats and tears.
Now, with the public spat between the Twitter admin and the TruthSocial admin, the rest of the world gets to enjoy a similar spectacle!
They can't defederate of course, because Twitter never became open enough and TruthSocial was already defederated by everyone as soon as it existed.
Only on Fedi can you get the full experience of a public spat and defederation, because only on Fedi can the admins really at-mention and and directly reply and take the final dramatic action of a flouce-defederation.
Trump fans who are Twitter users can't port their followers over to TruthSocial, and Turther Musk fans can't just migrate their account to Twitter.
They're stuck.
So you see Fedi really is the best when it comes to massive public spats between admins and this current admin-drama is only getting more attention because it's between two of the worst people in the world.

Capacitance-based Fermion parity read-out and predicted Rabi oscillations in a Majorana nanowire
Recent experiments have measured flux dependent capacitance at radio frequencies leading to the potential for a fast parity read-out of a Majorana qubit. In this work we argue that the quantum dot used in the capacitance measurement can be reasonably approximated by a non-interacting weakly coupled orbital. We then predict the measured flux and parity dependent capacitance for several parameter regimes of the disordered Majorana nanowire model that are both topological and trivial. Following th…

Principal Context-aware Diffusion Guided Data Augmentation for Fault Localization
Test cases are indispensable for conducting effective fault localization (FL). However, test cases in practice are severely class imbalanced, i.e. the number of failing test cases (i.e. minority class) is much less than that of passing ones (i.e. majority class). The severe class imbalance between failing and passing test cases have hindered the FL effectiveness. To address this issue, we propose PCD-DAug: a Principal Context-aware Diffusion guided Data Augmentation approach that generate syn…

My fair city of Roanoke attained “Bee City USA” status in 2022, which aims to “promote healthy, sustainable habitats for bees and other pollinators, responsible for the reproduction of nearly 90% of the world’s flowering plant species and one in every three bites of food we eat.”
Last night, a couple of garden clubs teamed up with the city to screen a new PBS Nature documentary, “My Garden of a Thousand Bees”.

My Garden of a Thousand Bees
New PBS documentary following wildlife filmmaker Martin Dohrn as he films more than 60 species of bees in his urban garden in Bristol, England, during the COVID-19 2020 lockdown.

Quenching of excitons at grain boundaries in C60 thin films
Exciton lifetimes play a critical role in the performance of organic optoelectronic devices. In this work, we investigate how the presence of multiple rotational domains, and therefore grain boundaries, impacts exciton dynamics in thin films of C60/Au(111) using time and angle-resolved photoemission spectroscopy (TR-ARPES). We find that films with multiple rotational domains exhibit shorter exciton lifetimes and evidence of exciton-exciton annihilation, even when one domain predominates. Scanni…

Quantum confinement theory of ultra-thin films: electronic, thermal and superconducting properties
The miniaturization of electronic devices has led to the prominence, in technological applications, of ultra-thin films with a thickness ranging from a few tens of nanometers to just about 1-2 nanometers. While these materials are still effectively 3D in many respects, traditional theories as well as ab initio methods struggle to describe their properties as measured in experiments. In particular, standard approaches to quantum confinement rely on hard-wall boundary conditions, which neglect th…
