"In a regulatory filing on Monday, Trump Media said it lost $58.2 million in 2023, compared with a profit of $50.5 million in 2022.
The Truth Social owner generated just $4.1 million in revenue, although that was up from $1.5 million in 2022.”
Honest question: how do you have $50M profit on $1.5M revenue? I seem to misunderstand the terms.

Trump’s net worth plunges $1 billion as his media stock tumbles
Truth Social owner Trump Media & Technology Group disclosed Monday that it lost more than $58 million and generated very little revenue in 2023.

Integrity is getting harder to find.
Twenty-four ways to know if you have it:
First, what integrity's not:
Doing what's popular instead of what's right
Acting differently in private than in public
Saying one thing and doing another
Letting fear dictate your decisions
Taking credit for others' work
Valuing success over ethics
Hiding your mistakes
Following the crowd
Turning a blind eye
Making excuses

Role of stress/strain in tailoring the magnetic and transport properties of magnetic thin films and multilayers
Magnetic anisotropy is a fundamental property of magnetic materials that determines the alignment of the spins along the preferential direction, called the easy axis of magnetization. Magnetic polycrystalline thin films offer several advantages over magnetic epitaxial thin films because of fabrication flexibility, higher coercivity and improved magnetic stability, higher magnetoresistance (useful in magneto-resistive devices such as magnetic field sensors and MRAM cells), cost-effectiveness and…

No U(1) 'electric-magnetic' duality in Einstein gravity
We revisit the question of whether classical general relativity obeys, beyond the linearised order, an analogue of the global U(1) electric-magnetic duality of Maxwell theory, with the Riemann tensor playing the role analogous to the field strength. Following contradictory claims in the literature, we present a simple gauge-invariant argument that the duality does not hold. The duality condition is the conservation of the helicity charge. Scattering amplitudes of gravitons in general relativity…

Direct, simple, and efficient computation of all components of the virtual-casing magnetic field in axisymmetric geometries with Kapur-Rokhlin quadrature
In a recent publication (Toler et al. 2023), we demonstrated that for axisymmetric geometries, the Kapur-Rokhlin quadrature rule provided an efficient and high-order accurate method for computing the normal component, on the plasma surface, of the magnetic field due to the toroidal current flowing in the plasma, via the virtual-casing principle. The calculation was indirect, as it required the prior computation of the magnetic vector potential from the virtual-casing principle, followed by the …

Integer and fractional quantum anomalous Hall effects in pentalayer graphene
We critically analyze the recently reported observation of integer (IQAHE) and fractional (FQAHE) quantum anomalous Hall effects at zero applied magnetic field in pentalayer graphene. Our quantitative activation and variable range hopping transport analysis of the experimental data reveals that the observed IQAHE and FQAHE at different fillings all have similar excitation gaps of the order of $5-10$ K. In addition, we also find that the observed FQAHE manifests a large hidden background contact…

Evolution of Berry Phase and Half-Metallicity in Cr$_2$Te$_3$ in Response to Strain, Filling, Thickness, and Surface Termination

Evolution of Berry Phase and Half-Metallicity in Cr$_2$Te$_3$ in Response to Strain, Filling, Thickness, and Surface Termination
Cr$_2$Te$_3$ is a ferromagnetic, quasi-two-dimensional layered material with perpendicular magnetic anisotropy, strong spin-orbit coupling, and non-trivial band topology. The non-trivial topology results in an intrinsic anomalous Hall conductivity (AHC) that switches sign under filling and biaxial strain. Thin films can exhibit half metallicity. Using density functional theory combined with maximally localized Wannier functions, we reveal the physical origins of the sensitivity of the sign of t…

I wish I could convey how awesome it could be to appreciate the come up to success it would be with other people instead of focusing on the people that disowned me and discarded me during my success. I'm on the way up and the following people have helped me: <null> Success is important, and I plan to take all of you people that have taken me up with me. <still null>
