Thermal stability and phase transformation of $α$-, $κ(ε)$-, and $γ$-Ga$_2$O$_3$ thin films to $β$-Ga$_2$O$_3$ under various ambient conditions
Phase transitions in metastable $α$-, $κ(ε)$-, and $γ$-Ga$_2$O$_3$ films to thermodynamically stable $β$-Ga$_2$O$_3$ during annealing in air, N$_2$, and vacuum have been systematically investigated via in-situ high-temperature X-ray diffraction and scanning electron microscopy. These respective polymorphs exhibited thermal stability to around 471-525$^\circ$C, 773-825$^\circ$C, and 490-575$^\circ$C before transforming into $β$-Ga$_2$O$_3$, across all tested ambient conditions.

Periodic orbits near collision in a restricted four-body problem for the eight choreography
We study orbits near collision in a non-autonomous restricted planar four-body problem. This restricted problem consists of a massless particle moving under the gravitational influence due to three bodies following the figure-eight choreography. We use regularized coordinates in order to deal numerically with motions near collision, and reversing symmetries to study both theoretically and numerically certain type of symmetric periodic orbits of the restricted system. The symmetric periodic orbi…

A census of graph-drawing algorithms based on generalized transversal structures
We define graph drawing algorithms which simultaneously generalize several classical ones. More precisely, we consider the following algorithms: (a) Fusy's algorithm for the straight-line grid drawing of planar triangulations, based on transversal structures, (b) Barrière and Huemmer's algorithm for the straight-line grid drawing of planar quadrangulations, based on separating decompositions, (c) He's algorithm for the orthogonal drawing of 3-valent planar maps, based on transversal stru…

Filled Colloidal Gel Rheology: Strengthening, Stiffening, and Tunability
Filler-induced strengthening is ubiquitous in materials science and is particularly well-established in polymeric nanocomposites. Despite having similar constituents, colloidal gels with solid filling exhibit distinct rheology, which is of practical interest to industry (e.g., lithium-ion batteries) yet remains poorly understood. We show, using experiments and simulations, that filling monotonically enhances the yield stress (i.e., strength) of colloidal gels while the elastic modulus (i.e., st…

Socratic Planner: Inquiry-Based Zero-Shot Planning for Embodied Instruction Following
Embodied Instruction Following (EIF) is the task of executing natural language instructions by navigating and interacting with objects in 3D environments. One of the primary challenges in EIF is compositional task planning, which is often addressed with supervised or in-context learning with labeled data. To this end, we introduce the Socratic Planner, the first zero-shot planning method that infers without the need for any training data. Socratic Planner first decomposes the instructions into …

Layer Coherence Origin of Intrinsic Planar Hall Effect in 2D Limit
The intrinsic planar Hall effect has attracted intensive interest inspired by recent experiments. Existing theories of this effect require three dimensional orbital motion, or strong spin-orbit coupling of certain forms, which do not exist in van der Waals thin films. Here, we uncover a new origin of the planar Hall effect - as an intrinsic property of layer coherent electrons - that allows its presence even in bilayer and trilayer atomically thin limit. As examples, we show that the effect can…

Got the Wiitek 10GbE copper SFP in and initial tests look pretty good. I'll put it through a bit more of its paces later, but I'm feeling a bit better with the dual 10GbE copper NICs in the new motherboard mostly because I'll be able to use them. #homelab #networking

New insights on the dynamics of satellite galaxies: effects of the figure rotation of a host galaxy
We investigate a mechanism to form and keep a planar spatial distribution of satellite galaxies in the Milky Way (MW), which is called the satellite plane. It has been pointed out that the ΛCDM cosmological model hardly explains the existence of such a satellite plane, so it is regarded as one of the serious problems in the current cosmology. We here focus on a rotation of the gravitational potential of a host galaxy, i.e., so-called a figure rotation, following the previous suggestion that th…

Can silica nanoparticles improve lithium transport in polymer electrolytes?
The question of if silica nanoparticles can enhance the ionic conductivity of a polymer electrolyte above its crystallization temperature has remained unclear for the two decades following the first experiments on these systems. We use Molecular Dynamics simulations to decipher the atomic scale mechanisms affecting the properties of LiTFSI-poly(ethylene oxide) electrolytes upon the addition of silica nanoparticles. At any ionic concentration, adding nanoparticles significantly decreases the con…

Bounding Clique Size in Squares of Planar Graphs
Wegner conjectured that if $G$ is a planar graph with maximum degree $Δ\ge 8$, then $χ(G^2)\le \left\lfloor \frac32Δ\right\rfloor +1$. This problem has received much attention, but remains open for all $Δ\ge 8$. Here we prove an analogous bound on $ω(G^2)$: If $G$ is a plane graph with $Δ(G)\ge 36$, then $ω(G^2)\le \lfloor\frac32Δ(G)\rfloor+1$. In fact, this is a corollary of the following lemma, which is our main result. If $G$ is a plane graph with $Δ(G)\ge 19$ and $S$ is a maximal c…
