Asteroidal quadruples in non rooted path graphs [PDF]

open access: yes, 2019
A directed path graph is the intersection graph of a family of directed subpaths of a directed tree. A rooted path graph is the intersection graph of a family of directed subpaths of a rooted tree. Rooted path graphs are directed path graphs.

Non-crossing shortest paths in planar graphs with applications to max flow, and path graphs [PDF]

open access: yes, 2023
This thesis is concerned with non-crossing shortest paths in planar graphs with applications to st-max flow vitality and path graphs. In the first part we deal with non-crossing shortest paths in a plane graph G, i.e., a planar graph with a fixed planar

Aspect-Category-Opinion-Sentiment Quadruple Extraction with Implicit Aspects and Opinions

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2021
Product reviews contain a large number of implicit aspects and implicit opinions. However, most of the existing studies in aspect-based sentiment analysis ignored this problem.

Asteroidal Sets and Dominating Targets in Graphs [PDF]

open access: yes
The focus of this Ph.D. thesis is on various distance and domination properties in graphs. In particular, we prove strong results about the interactions between asteroidal sets and dominating targets. Our results add to or extend a plethora of results on

Spruce Budworm Defoliation Influences Greenhouse Gas Concentrations in Streams

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract One of the most significant natural disturbances in the Canadian boreal and hemiboreal forest is tree defoliation by eastern spruce budworm (SBW), which may increase nutrient and carbon inputs to catchment soils, and in runoff. Closely connected to catchments, headwater streams are known to be significant emitters of greenhouse gases (GHGs ...

On the Stability Barrier of Hermite Type Discretizations of Advection Equations

open access: yesNumerical Methods for Partial Differential Equations, Volume 42, Issue 1, January 2026.
ABSTRACT We establish a stability barrier for a class of high‐order Hermite‐type discretization of 1D advection equations underlying the hybrid‐variable (HV) and active flux (AF) methods. These methods approximate both cell averages and nodal solutions and evolve them in time simultaneously.

Meteorological Tsunamis: From Local Hazard to Global Relevance

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Research on meteorological tsunamis or meteotsunamis—long ocean waves in the tsunami frequency band generated by propagating atmospheric disturbances which resonantly enhance ocean waves—has grown significantly in recent decades. This expansion is due to progress in (a) ocean and atmospheric measurements, including advanced instrumentation ...

Sulfur‐bearing serpentine in carbonaceous chondrites

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 12, Page 2864-2890, December 2025.
Abstract A correlative multi‐technique approach, including electron microscopy and X‐ray synchrotron work, has been used to obtain both structural and compositional information of a sulfur‐bearing serpentine identified in several carbonaceous chondrites (Winchcombe CM2, Aguas Zarcas CM2, Ivuna CI, and Orgueil CI), and in Ryugu samples returned by the ...

Growth of asteroids, planetary embryos, and Kuiper belt objects by chondrule accretion [PDF]

open access: yesScience Advances, 2015
Chondrules, tiny spheres found in primitive meteorites, accumulate through gas drag to form asteroids and planetary embryos. Chondrules are millimeter-sized spherules that dominate primitive meteorites (chondrites) originating from the asteroid belt. The

A Study Demonstrating That Using Gravitational Offset to Prepare Extraterrestrial Mobility Missions Is Misleading

open access: yesJournal of Field Robotics, Volume 42, Issue 7, Page 3772-3794, October 2025.
ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...
