Everything that has made this nation a shining beacon in any way whatsoever is being dismantled

Non-Ferroelectric to Ferroelectric Phase Transition in epitaxial Y:HfO$_2$ via Rapid Thermal Annealing Induced Nitrogen Doping
Oxygen vacancies are often essential for stabilizing the orthorhombic ferroelectric phase in HfO$_2$, with cationic doping widely employed to introduce such defects. In contrast, systematic studies on anionic doping to induce ferroelectricity remain largely in nascent stages. On epitaxial Y:HfO$_2$ grown on ITO buffered YSZ substrates that crystallize in a mixed monoclinic (non-polar) and orthorhombic (polar) phases, we introduce nitrogen doping via post deposition rapid thermal annealing (RTA)…

Best bounds for the dual Hardy operator minus identity on decreasing functions
The distance from the identity operator $I$ to $H^*$, the dual of the Hardy averaging operator, is studied on the cone of nonnegative, nonincreasing functions in Lebesgue space. The exact value is obtained. Optimal lower bounds are also given for difference, $H^*-I$, of these two operators acting on the same cone. A positive answer is given to a conjecture made in ``The norm of Hardy-type oscillation operators in the discrete and continuous settings'' by A. Ben Said, S. Boza, and J. Soria. Prep…

Bifurcation in optimal retirement
We study optimal consumption and retirement using a Cobb-Douglas utility and a simple model in which an interesting bifurcation arises. With high wealth, individuals plan to retire. With low wealth they plan to never retire. At a critical level of initial wealth they may choose to defer this decision, leading to a continuum of wealth trajectories with identical utilities.

GATEBLEED: Exploiting On-Core Accelerator Power Gating for High Performance & Stealthy Attacks on AI
As power consumption from AI training and inference continues to increase, AI accelerators are being integrated directly into the CPU. Intel's Advanced Matrix Extensions (AMX) is one such example, debuting on the 4th generation Intel Xeon Scalable CPU. We discover a timing side and covert channel, GATEBLEED, caused by the aggressive power gating utilized to keep the CPU within operating limits. We show that the GATEBLEED side channel is a threat to AI privacy as many ML models such as transform…
