What does a binary black hole merger look like? [PDF]
, 2015 We present a method of calculating the strong-field gravitational lensing caused by many analytic and numerical spacetimes. We use this procedure to calculate the distortion caused by isolated black holes and by numerically evolved black hole binaries ...

Multimodal Locomotion of Soft Robots
Advanced Intelligent Systems, EarlyView.This review comprehensively surveys recent advances in multimodal locomotion within soft robotics. Typical locomotion modes are summarized and categorized. Furthermore, the underlying mechanisms enabling multimodal locomotion are discussed and classified into three primary categories: active control‐based, reconfiguration‐based, and environment ...

Time delay of photons coupled to Weyl tensor in a regular phantom black hole
European Physical Journal C: Particles and Fields, 2020 Time delay of the photons coupled to the Weyl tensor in a regular phantom black hole is investigated in both weak and strong deflection gravitational lensing. We find that the time delay in the weak deflection lensing strongly depends on the phantom hair

Possible Discrimination of Black Hole Origins from the Lensing Rate of DECIGO and B-DECIGO Sources
The Astrophysical Journal, 2023 In this paper, we forecast the expected detection rates and redshift distributions of gravitationally lensed gravitational waves (GWs) from three different mass distributions of primordial black holes (PBHs) and two stellar formation models of ...

, 2021 Strong gravitational lensing of gravitational waves can produce duplicate signals separated in time with different amplitudes. We consider the case in which strong lensing produces identifiable gravitational-wave events and weaker sub-threshold signals ...

Resolving the discrepancy between X-ray and gravitational lensing mass measurements for clusters of galaxies [PDF]
, 1997 We present a detailed comparison of mass measurements for clusters of galaxies using ASCA and ROSAT X-ray data and constraints from strong and weak gravitational lensing.

Anatomical Sciences Education, EarlyView.Abstract While gamified learning platforms show promise for engaging digital learners and promoting active learning, evidence of their effectiveness in predicting academic outcomes remains limited. This study examined how engagement patterns and incentives impact academic outcomes in a gamified environment to determine whether a formative question bank

Periodontology 2000, EarlyView., 2023 Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

Quasar Milli-lensing and Cold Dark Matter (TNG50) Subhaloes. I. Image Splitting
The Astrophysical JournalWe use numerical mass density profiles from the TNG50 simulation to study the impact of gravitational milli-lensing by dark matter subhaloes on the images of lensed quasars.

The necessity of dark matter in MOND within galactic scales
, 2007 To further test MOdified Newtonian Dynamics (MOND) on galactic scales -- originally proposed to explain the rotation curves of disk galaxies without dark matter -- we study a sample of six strong gravitational lensing early-type galaxies from the CASTLES
