Geodesics Using Mathematica [PDF]
, 2017 We describe surfaces and geodesics without assuming prior knowledge of differential geometry. This involves selecting and presenting basic definitions and theorems.

Metamorphic Geodesic Regression [PDF]
, 2012 We propose a metamorphic geodesic regression approach approximating spatial transformations for image time-series while simultaneously accounting for intensity changes. Such changes occur for example in magnetic resonance imaging (MRI) studies of the developing brain due to myelination.

The 2025 Kamchatka Earthquake and Tsunami: Cascading Impacts and Risks to Japan
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT On July 29th, 2025, a large earthquake (Mw 8.8) occurred near the Kamchatka Peninsula. This event caused a tsunami that reached Japan's Pacific coast, even though the source was far away. In this study, we analyze the characteristics of earthquakes and tsunamis and discuss how they relate to the recurrence possibility and risk in Japan.

Geodesics in digital pictures [PDF]
, 1978 Digital ares which are shortest paths between their endpoints are called (digital) geodesics. Several characterizations of such geodesics are given. In particular, it is shown that the are A is a geodesic if and only if equal chords of (subarcs of) A ...

Black-Box Optimization Using Geodesics in Statistical Manifolds
Entropy, 2015 Information geometric optimization (IGO) is a general framework for stochastic optimization problems aiming at limiting the influence of arbitrary parametrization choices: the initial problem is transformed into the optimization of a smooth function on a

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.

The Entropy-Based Quantum Metric
Entropy, 2014 The von Neumann entropy S( D ^ ) generates in the space of quantum density matrices D ^ the Riemannian metric ds2 = −d2S( D ^ ), which is physically founded and which characterises the amount of quantum information lost by mixing D ...

Frames of quasi-geodesics, visibility and geodesic loops
, 2023 In this paper we give a characterization in terms of ``quasi-geodesics frames' of visibility and existence of geodesic loops for bounded domains in $\mathbb C^d$ which are Kobayashi complete hyperbolic and Gromov hyperbolic.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Earthquake‐induced damage of structures can trigger cascading hazards, linking structural performance to nonstructural consequences. In current engineering practice, these two aspects are typically addressed separately, limiting the ability to account for such coupled effects in design.
