The long-term Swift monitoring of ESO 243-49 HLX-1 provides an opportunity to investigate the detailed timing and spectral behaviour of this hyper-luminous X-ray source. Swift has…
Hybrid integration methods for on-chip quantum photonics
Je-Hyung Kim, Shahriar Aghaeimeibodi, Jacques Carolan +2
The goal of integrated quantum photonics is to combine components for the generation, manipulation, and detection of non-classical light in a phase stable and efficient platform. S…
Phase Instability amid Dimensional Crossover in Artificial Oxide Crystal
Seung Gyo Jeong, Taewon Min, Sungmin Woo +13
Artificial crystals synthesized by atomic-scale epitaxy provides the ability to control the dimensions of the quantum phases and associated phase transitions via precise thickness…
Large Area Automated Characterisation of Chemical Vapour Deposition Grown Monolayer Transition Metal Dichalcogenides Through Photoluminescence Imaging
T. Severs Millard, A. Genco, E. M. Alexeev +5
CVD growth is capable of producing multiple single crystal islands of atomically thin TMDs over large area substrates, with potential control of their morphology, lateral size, and…
Why Do Masked Neural Language Models Still Need Common Sense Knowledge?
Sunjae Kwon, Cheongwoong Kang, Jiyeon Han +1
Currently, contextualized word representations are learned by intricate neural network models, such as masked neural language models (MNLMs). The new representations significantly…
Infrared study of Large scale h-BN film and Graphene/h-BN heterostructure
Kwangnam Yu, Jiho Kim, Chul Lee +5
We synthesize a series of CVD h-BN films and perform critical infrared spectroscopic characterization. For high-temperature (HT, Temp = 1400 degrees) grown h-BN thin film only E1u-…
ST-GRAT: A Novel Spatio-temporal Graph Attention Network for Accurately Forecasting Dynamically Changing Road Speed
Cheonbok Park, Chunggi Lee, Hyojin Bahng +5
Predicting road traffic speed is a challenging task due to different types of roads, abrupt speed change and spatial dependencies between roads; it requires the modeling of dynamic…
Reaching and violating thermodynamic uncertainty bounds in information engines
Govind Paneru, Sandipan Dutta, Tsvi Tlusty +1
Thermodynamic uncertainty relations (TURs) set fundamental bounds on the fluctuation and dissipation of stochastic systems. Here, we examine these bounds, in experiment and theory,…
