Base Semantics—A Novel Approach for Minimizing Malware Detection Rules

open access: yesSECURITY AND PRIVACY, Volume 9, Issue 6, November/December 2026.
ABSTRACT The rapid evolution of malware variants has increasingly undermined traditional signature‐based detection techniques, which are easily evaded through obfuscation and polymorphism that preserve malicious functionality. This challenge is particularly acute in Internet of Things (IoT) environments, where device heterogeneity, resource constraints,

The Balloon Lidar Experiment BOLIDE [PDF]

open access: yes, 2019
The Balloon Lidar Experiment BOLIDE was the first mesospheric lidar system carried by a long duration balloon. As part of NASA’s PMC-Turbo balloon payload, the lidar was launched from Kiruna, Sweden in July 2018 on a six day mission to northern Canada.

Direct Measurement of Explosive Impulse From Contact to the Ultra‐Near Field

open access: yesPropellants, Explosives, Pyrotechnics, Volume 51, Issue 10, Page 1721-1736, October 2026.
ABSTRACT Measurement of impulse from explosive charges in contact and ultra‐near‐field regimes remains poorly characterised due to the short duration of loading, high strain rates, and the difficulty of obtaining direct momentum‐based measurements.

Island life in the Cretaceous - faunal composition, biogeography, evolution, and extinction of land-living vertebrates on the Late Cretaceous European archipelago

open access: yesZooKeys, 2015
The Late Cretaceous was a time of tremendous global change, as the final stages of the Age of Dinosaurs were shaped by climate and sea level fluctuations and witness to marked paleogeographic and faunal changes, before the end-Cretaceous bolide impact ...

Oceans, Lakes, and Stromatolites on Mars

open access: yesAdvances in Astronomy, 2020
Billions of years ago, the Northern Hemisphere of Mars may have been covered by at least one ocean and thousands of lakes and rivers. These findings, based initially on telescopic observations and images by the Mariner and Viking missions, led ...

Experimental Aeolian Abrasion of Basalt Sands as an Analog for Producing Martian Dust

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Dust covers a significant portion of Mars' surface, with dust storms periodically engulfing the planet. Despite this, the origins of Martian dust are poorly understood, especially for ancient dust deposits. To address this deficit, we conducted experiments to replicate the mechanical abrasion of saltating sand grains in a Martian desert dune ...

A Comparison of Automated Bolide Detection Methods [PDF]

open access: yes, 2023
Bolide recording and analysis are crucial so meteoroid fragments can be found, a lightcurve analyzed, and its trajectory calculated. The Spalding Allsky Camera Network (SACN) generates videos and composite images of the night sky that are potential ...

Болід [Bolid]

open access: yes, 2004
БОЛІ́Д (від грец. βολίς – метальний спис) – яскравий метеор, блиск якого при спостереженні з Землі перевищує блиск планети Венера. Тому яскраві Б. можна спостерігати і вдень. Б. – тверді космічні частинки, які входять у земну атмосферу зі швидкістю від 11 до 72 км/сек. і мають ма... ⚠️ Цей запис містить лише бібліографічні метадані.

Life After Impact: Paleobathymetric Gradients in Post‐K/Pg Nannoplankton Boom‐Bust Successions

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract The Cretaceous/Paleogene (K/Pg) bolide impact ∼66 Ma caused the near‐demise of calcareous nannoplankton–key primary producers and major components of the biological pump that exports organic and inorganic carbon to the deep sea. Despite their ecological significance, resolving the exact impact of nannoplankton's mass extinction on ecosystem ...
