The resolved jet of 3C 273 at 150 MHz : Sub-arcsecond imaging with the LOFAR international baselines
(2022-02-01)Context. Since its discovery in 1963, 3C 273 has become one of the most widely studied quasars with investigations spanning the electromagnetic spectrum. While much has therefore been discovered about this historically ... -
Thermoresponsive Triblock‐Copolymers of Polyethylene Oxide and Polymethacrylates: Linking Chemistry, Nanoscale Morphology, and Rheological Properties
(2022-02-23)Abstract: Thermoreversible gels switch from a free‐flowing liquid state to an elastic gel mesophase upon warming, displaying the reverse transition upon cooling. While this phenomenon makes these advanced materials highly ... -
Predicting the Strength of Cohesive and Adhesive Interparticle Interactions for Dry Powder Inhalation Blends of Terbutaline Sulfate with α‑Lactose Monohydrate
(2023-09-08)Grid-based systematic search methods are used to investigate molecule–molecule, molecule–surface, and surface–surface contributions to interparticle interactions in order to identify the crystal faces that most strongly ... -
Low frequency radio properties of the $z>5$ quasar population
(2021-12-31)Optically luminous quasars at z > 5 are important probes of super-massive black hole (SMBH) formation. With new and future radio facilities, the discovery of the brightest low-frequency radio sources in this epoch would ... -
Shifting narratives of the Self – students’ experiences of chronicity and multiplicity in the management of chronic illness at university
(2023-09-30)Drawing on the chronic illness scholarship and identity theories, this paper aims to deepen the understanding of the biographical disruptions experienced by undergraduate students living with a long-term health condition. ... -
PRAiSE: resolved spectral evolution in simulated radio sources
(2022-04-30)We present a method for applying spatially resolved adiabatic and radiative loss processes to synthetic radio emission from hydrodynamic simulations of radio sources from active galactic nuclei (AGN). Lagrangian tracer ... -
Non-star-forming molecular gas in the Abell 1367 intra-cluster multiphase orphan cloud
(2022-02-04)We report the detection of CO emission in the recently discovered multiphase isolated gas cloud in the nearby galaxy cluster Abell 1367. The cloud is located about 800 kpc in projection from the center of the cluster and ... -
The Planck clusters in the LOFAR sky. I. LoTSS-DR2 new detections and sample overview
(2022-04-30)Context. Relativistic electrons and magnetic fields permeate the intra-cluster medium (ICM) and manifest themselves as diffuse sources of synchrotron emission observable at radio wavelengths, namely radio halos and radio ... -
The Numerical Inversion of the Laplace Transform in a Multi-Precision Environment.
(2022-05-23)This paper examines the performance of five algorithms for numerically inverting the Laplace transform, in standard, 16-digit and multi-precision environments. The algorithms are taken from three of the four main classes ... -
Hollywood’s Peerless Advocate for Israel: Max Nussbaum, ‘Rabbi to the Stars’
(2023-08-25)A neglected figure in the histories of Zionism, American Jewry and US-Israel relations, Max Nussbaum carved out a highly unusual place for himself in Hollywood after the Second World War. Known affectionately as the ‘Rabbi ... -
The environmental dependence of the stellar and gas-phase mass-metallicity relation at 2 < z < 4
(2022-08-30)In the local universe, galaxies in clusters show different properties compared to more isolated systems. Understanding how this difference originates and whether it is already in place at high redshift is still a matter ... -
Non-thermal radio continuum emission from young nearby stars
(2022-05-23)Young and magnetically active low-mass stars often exhibit non-thermal coronal radio emission due to the gyration of electrons in their magnetized chromospheres. This emission is easily detectable at centimeter wavelengths ... -
TRENDS AND PROSPECTS OF DIGITAL TWIN TECHNOLOGIES: A REVIEW
(2022-12-18)The plethora of technologically developed software and digital types of machinery are widely applied for industrial production and the digitalization of building technologies. The fourth industrial revolution and the ... -
“A Toste wett in Muskadine”: Preventing Miscarriage in Early Modern English Recipe Books c.1600–1780
(2022-11-29)Discussions about early modern miscarriage have considered in detail how women rationalised miscarriage framing the emotional burden of loss within the context of providence and sin. This valuable interpretation considers ... -
Inductive Transfer and Deep Neural Network Learning-Based Cross-Model Method for Short-Term Load Forecasting in Smarts Grids
(2023-05-23)In a real-world scenario of load forecasting, it is crucial to determine the energy consumption in electrical networks. The energy consumption data exhibit high variability between historical data and newly arriving data ... -
Experimental Validation of a Mitigation Method of Ferranti Effect in Transmission Line
(2023-02-14)Electric power transmission networks should be operated in efficient, safe, and reliable conditions. To improve the stability and transfer capability of power transmission, it is necessary to mitigate the Ferranti effect. ... -
Optimal Coordination of Directional Overcurrent Relays Using Hybrid Firefly–Genetic Algorithm
(2023-07-12)The application of directional overcurrent relays (DOCRs) plays an important role in protecting power systems and ensuring their safe, reliable, and efficient operation. However, coordinating DOCRs involves solving a highly ... -

Population statistics of intermediate-mass black holes in dwarf galaxies using the NEWHORIZON simulation
(2023-08-01)While it is well established that supermassive black holes (SMBHs) coevolve with their host galaxy, it is currently less clear how lower-mass black holes, so-called intermediate-mass black holes (IMBHs), evolve within their ... -
Tree-level color–kinematics duality implies loop-level color–kinematics duality up to counterterms
(2023-04-01)Color–kinematics (CK) duality is a remarkable symmetry of gluon amplitudes that is the key to the double copy which links gauge theory and gravity amplitudes. Here we show that the complete Yang–Mills action itself, including ...
