Radio Continuum Studies of Ultra-Compact and Short Orbital Period X-Ray Binaries
We present the radio continuum counterparts to the enigmatic ultra-compact X-ray binaries (UCXBs); a black hole or neutron star accreting from a hydrogen-deficient white dwarf donor star, with short orbital periods ($<$ 80 minutes). For the sample of UCXBs hosted by globular clusters (GCs), we search for whether certain GC properties are more likely to enhance UCXB formation. We determine that GCs which host UCXBs are drawn from a distinct population in terms of cluster concentration, core radi…

A Comprehensive Multiwavelength Study of the OH Megamaser galaxy IRAS 09320+6134
We present a multiwavelength study of the gas distribution, kinematics and excitation of the OH megamaser galaxy IRAS 09320+6134 (UGC 5101) using Gemini Multi-Object Spectrograph Integral Field Unit, Hubble Space Telescope, and Very Large Array observations. The HST ACS F814W i-band and H$α$ + [N II] $λλ$ 6548,84 narrow-band images indicate that this galaxy is a late-stage merger. The ionized gas emission in the inner $\sim$ 2 kpc radius, traced by the GMOS data, is consistent with two kinem…

Integrated phononic waveguide on thin-film lithium niobate on diamond
We demonstrate wavelength-scale phononic waveguides formed by transfer-printed thin-film lithium niobate (LN) on bulk diamond (LNOD), a material stack that combines the strong piezoelectricity of LN with the high acoustic velocity and color-center compatibility of diamond. We characterize a delay line based on a 100 micron long phononic waveguide at room and cryogenic temperatures. The total insertion loss through the device at 4 kelvin is -5.8 dB, corresponding to a >50% transducer efficiency,…

Electronic conduction in copper-graphene composites with functional impurities
Coal-derived graphene-like material and its addition to FCC copper are investigated using ab initio plane wave density functional theory (DFT). We explore ring disorder in the sp2 carbon, and functional impurities such as oxides (-O), and hydroxides (-OH) that are common in coal-derived graphene. The electronic density of states analysis revealed localized states near the Fermi level, with functional groups contributing predominantly to states below the Fermi level, while carbon atoms in non-he…

Chemical segregation analysed with unsupervised clustering
Molecular emission is a powerful tool for studying the physical and chemical structures of dense cores. The distribution and abundance of different molecules provide information on the chemical composition and physical properties in these cores. We study the chemical segregation of three molecules (c-C$_3$H$_2$, CH$_3$OH, CH$_3$CCH) in the starless cores B68 and L1521E, and the prestellar core L1544. We applied the density-based clustering algorithms DBSCAN and HDBSCAN to identify chemical and …

Concentration profiles of OH and H$_2$O$_2$ in plasma-treated water: influence of power, gas mixture and treatment distance
Plasma liquid interactions are important for a range of applications. For these, H$_2$O$_2$ and OH represent two key reactive species, whose concentrations in liquids need to be controlled for effective application outcomes. Here, a combination of gas and liquid simulations is used to study the concentration profiles of H$_2$O$_2$ and OH in water treated by a radio-frequency-driven plasma jet, with a glass capillary between the electrodes, operated in He with admixtures of water vapour. Simulat…

End-to-End Photodissociation Dynamics of Energized H$_2$COO
The end-to-end dynamics of the smallest energized Criegee intermediate, H$_2$COO, was characterized for vibrational excitation close to and a few kcal/mol above the barrier for hydrogen transfer. From an aggregate of at least 5 $μ$s of molecular dynamics simulations using a neural network-representation of CASPT2/aug-cc-pVTZ reference data, the branching ratios into molecular products HCO+OH, CO$_2$+H$_2$, or H$_2$O+CO was quantitatively determined. Consistent with earlier calculations and rec…

Experimental Design for Semiparametric Bandits
We study finite-armed semiparametric bandits, where each arm's reward combines a linear component with an unknown, potentially adversarial shift. This model strictly generalizes classical linear bandits and reflects complexities common in practice. We propose the first experimental-design approach that simultaneously offers a sharp regret bound, a PAC bound, and a best-arm identification guarantee. Our method attains the minimax regret $\tilde{O}(\sqrt{dT})$, matching the known lower bound for …

A Multi-Electronic-State Model to Interpret the Apparent Anomalous Arrhenius Curve of OH HO$_2$ $\to$ O$_2$ H$_2$O

A Multi-Electronic-State Model to Interpret the Apparent Anomalous Arrhenius Curve of OH + HO$_2$ $\to$ O$_2$ + H$_2$O
A comprehensive multi-electronic-state model for OH + HO2 -> O2 + H2O has been developed through extensive multi-reference configuration interaction (MRCI) calculations, aiming to elucidate two key experimental observations: (1) an unusually deep and narrow ``well'' in the Arrhenius curve near 1100K and (2) a slightly negative temperature dependence in the range of 200K~500K. Moreover, the present model can serve as the basis for constructing multi-state Hamiltonian in multi-dimensional quantum…

Proof of a magnificent conjecture
Motivated by super-Yang-Mills theory on a Calabi-Yau 4-fold, Nekrasov and Piazzalunga have assigned weights to $r$-tuples of solid partitions and conjectured a formula for their weighted generating function. We define $K$-theoretic virtual invariants of Quot schemes of 0-dimensional quotients of $\mathcal{O}_{\mathbb{C}^4}^{\oplus r}$ by realizing them as zero loci of isotropic sections of orthogonal bundles on non-commutative Quot schemes. Via the Oh-Thomas localization formula, we recover N…
