Remarks of President Joe Biden -- State of the Union Address As Prepared for Delivery | The White House
The United States Capitol Good evening.  Mr. Speaker. Madam Vice President. Members of Congress. My Fellow Americans.  In January 1941, President Franklin Roosevelt came to this chamber to speak to the nation.  He said, “I address you at a moment unprecedented in the history of the Union.”  Hitler was on the march. War was raging in Europe.  President Roosevelt’s purpose was to wake up the…

Understanding Physical Breakdowns in Virtual Reality
Virtual Reality (VR) moves away from well-controlled laboratory environments into public and personal spaces. As users are visually disconnected from the physical environment, interacting in an uncontrolled space frequently leads to collisions and raises safety concerns. In my thesis, I investigate this phenomenon which I define as the physical breakdown in VR. The goal is to understand the reasons for physical breakdowns, provide solutions, and explore future mechanisms that could perpetuate s…

Tilings of Flat Tori by Congruent Hexagons
Convex hexagons that can tile the plane have been classified into three types. For the generic cases (not necessarily convex) of the three types and two other special cases, we classify tilings of the plane under the assumption that all vertices have degree $3$. Then we use the classification to describe the corresponding hexagonal tilings of flat tori and their moduli spaces.

Well-posedness of the 2D surface quasi-geostrophic equation in variable Lebesgue spaces
In this paper, we are mainly concerned with the well-posedness of the dissipative surface quasi-geostrophic equation in the framework of variable Lebesgue spaces. Based on some analytical results developed in the variable Lebesgue spaces and the $L^{p}$-$L^{q}$ decay estimates of the fractional heat kernel, we establish, for the 2D dissipative surface quasi-geostrophic equation, the global well-posedness in the space $\mathcal{L}^{p(\cdot)}_{\frac{2}{α-1}}(\mathbb{R}^{2},L^{\infty}(0,\infty))$…

As lawmakers prepare to take up NOAA funding, conservation groups demand $300M spending hike for endangered marine species
The agency’s program for protecting marine mammals, sea turtles and other threatened wildlife remains underfunded, advocates say — while some species face extinction by as early as midcentu.

Nonstandard diffeology and generalized functions
We introduce a nonstandard extension of the category of diffeological spaces, and demonstrate its application to the study of generalized functions. Just as diffeological spaces are defined as concrete sheaves on the site of Euclidean open sets, our nonstandard diffeological spaces are defined as concrete sheaves on the site of open subsets of nonstandard Euclidean spaces, i.e. finite dimensional vector spaces over (the quasi-asymptotic variant of) Robinson's hyperreal numbers. It is shown that…
