Dissecting the Diffuse Emission of the Galaxy with the HAWC Observatory
Galactic diffuse gamma-ray emission is produced by the interaction of high-energy cosmic rays propagating through the Milky Way with interstellar gas and radiation fields. Its measurement can provide crucial insights into the acceleration and transport of cosmic rays throughout our Galaxy. Here, we present a new analysis of the TeV Galactic diffuse gamma-ray emission using 8 years of HAWC data. This data was processed with the updated Pass 5 processing, enhancing the sensitivity and resolution …

Detecting and characterising the magnetic field of exoplanets
Magnetic fields play a crucial role in planetary evolution and habitability. While the intrinsic magnetic fields of solar system planets are relatively well understood, the magnetic properties of exoplanets remain largely unconstrained, despite their potential ubiquity. Detecting exoplanetary magnetic fields is essential to advancing our understanding of planetary habitability beyond the solar system. This paper focuses on two promising spectropolarimetric techniques for detecting magnetic fiel…

Computational Modelling of Thixotropic Multiphase Fluids
Multiphase systems are ubiquitous in engineering, biology, and materials science, where understanding their complex interactions and rheological behavior is crucial for advancing applications ranging from emulsion stability to cellular phase separation. This study presents a numerical methodology for modeling thixotropic multiphase fluids, emphasizing the transient behavior of viscosity and the intricate interactions between phases. The model incorporates phase-dependent viscosities, interfacia…

Harnessing the Power of Interleaving and Counterfactual Evaluation for Airbnb Search Ranking
Evaluation plays a crucial role in the development of ranking algorithms on search and recommender systems. It enables online platforms to create user-friendly features that drive commercial success in a steady and effective manner. The online environment is particularly conducive to applying causal inference techniques, such as randomized controlled experiments (known as A/B test), which are often more challenging to implement in fields like medicine and public policy. However, businesses face…

Mapping Magnetic Fields from Clouds to Cores with PRIMAger
High-resolution, wide-area mapping of magnetic field geometries within molecular clouds, and the star-forming filaments and cores within them, is crucial in order to understand the role of magnetic fields in the star formation process. We therefore propose an unbiased survey of star-forming molecular clouds within 0.5 kpc of the Earth in polarized light with the PRIMAger Polarimetry Imager. We will map magnetic fields over entire molecular clouds at linear resolutions of $\sim10^{-3}-10^{-2}$ p…

Looks like the #dana floods in Valencia last October. Massive rainfall in a matter of hours like nothing people have experienced before.
Dozens dead, many missing.
And the US Administration wants to do everything possible to slow the transition away from greenhouse gas emitting society.

Statistics of Residual Stress in Random Microstructures: Mean-Field Estimates and Full-Field Validations
Fluctuations of local fields are crucial for the prediction of failure in random composites across different scales as well as estimating the inelastic behaviour of it. This can be quantified statistically through second moments of the local fields, which can be quickly estimated using mean field homogenization (MFH). However, the exact fluctuation field can be estimated using full-field methods though it comes at the cost of intensive computational resources and limited scalability to complex …

Influence of oxygen-defects on intraband terahertz conductivity of carbon nanotubes
The exceptional charge transport properties of single-walled carbon nanotubes (SWCNTs) enable numerous ultrafast optoelectronic applications. Modifying SWCNTs by introducing defects significantly impacts the performance of nanotube-based devices, making defect characterization crucial. This research tracked these effects in oxygen plasma-treated SWCNT thin films. Sub-picosecond electric fields of varying strengths and additional photoexcitation were used to assess how defects influence charge c…

Kelvin-Helmholtz instability in binary fluids with miscibility gap
The isothermal spatio-temporal evolution of an interface between binary fluids, with temperature sensitive miscibility gap, subjected to shear flow is investigated using direct numerical simulations. The thermophysical properties and the interfacial tension in such fluids exhibit a dynamic temperature dependence based on the degree of miscibility. These fluid pairs can therefore be deployed in crucial microfluidic applications involving enhancement of liquid-liquid mass transfer. In this study,…
