Interfaces in Numerical Relativistic hydrodynamics

open access: yes, 2010
This thesis investigates numerical techniques for modelling sharp interfacesbetween relativistic fluids. The motivation for this work lies in obtaining accuratemodels of neutron star interiors for use in multidimensional simulationsin general relativity.

Investigating the Cosmological Rate of Compact Object Mergers from Isolated Massive Binary Stars

open access: yesThe Astrophysical Journal
Gravitational-wave (GW) detectors are observing compact object mergers from increasingly far distances, revealing the redshift evolution of the binary black hole (BBH)—and soon the black hole–neutron star (BHNS) and binary neutron star (BNS)—merger rate.

Enhancement of Circular Dichroism in Chiral Dielectric Metasurfaces by Ion Beam Irradiation

open access: yesAdvanced Optical Materials, EarlyView.
Ion beam irradiation enables post fabrication tuning of dissipative losses in chiral dielectric metasurfaces composed of C4 symmetric silicon nanostructures. By tailoring the absorption toward critical coupling condition, circular dichroism is enhanced from 0.70 to 0.85, demonstrating a versatile route for maximizing optical chirality and polarization ...

Detecting Gravitational Wave Bursts from Stellar-mass Binaries in the mHz Band

open access: yesThe Astrophysical Journal
The dynamical formation channels of gravitational wave (GW) sources typically involve a stage when the compact object binary source interacts with the environment, which may excite its eccentricity, yielding efficient GW emission.

Scalable Task Planning via Large Language Models and Structured World Representations

open access: yesAdvanced Robotics Research, EarlyView.
This work efficiently combines graph‐based world representations with the commonsense knowledge in Large Language Models to enhance planning techniques for the large‐scale environments that modern robots will need to face. Planning methods often struggle with computational intractability when solving task‐level problems in large‐scale environments ...

A KKM-RESULT AND AN APPLICATION FOR BINARY AND NON-BINARY CHOICE FUNCTIONS [PDF]

open access: yes
By generalizing the classical Knaster-Kuratowski-Mazurkiewicz Theorem, we obtain a result that provides sufficient conditions to ensure the non-emptiness of several kinds of choice functions. This result generalizes well-known results on the existence of

On the formation of strange quark stars from supernova in compact binaries

open access: yesJournal of High Energy Astrophysics
Strange quark stars (SQSs), namely compact stars entirely composed of deconfined quark matter, are characterized by similar masses and compactness to neutron stars (NSs) and have been theoretically proposed to exist in the Universe since the 1970s.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

open access: yesAdvanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Shaping the Outflows of Binary AGB Stars

open access: yes, 2015
The required conditions for stars to evolve into planetary nebulae (PNe) continue to puzzle. Since PNe are found in a wide variety of shapes, processes that could sculpt circumstellar envelopes (CSEs) are being investigated.
