The evaluation of geosites in the territory of National park „Kopaonik“(Serbia)

Open Geosciences, 2018
In the relatively small area of the National Park (NP) „Kopaonik“ a lot of exogenous and endogenous processes took part and continue to act until present day.

Saharan dust linked to European hail events [PDF]

Atmospheric Chemistry and Physics
Saharan dust significantly influences hail occurrence in Europe. Using Copernicus Atmosphere Monitoring Service (CAMS) and reanalysis data, crowd-sourced hail reports, lightning data, and radar measurements, we find a strong correlation between elevated ...

Quantum leakage detection using a model-independent dimension witness

, 2019
Users of quantum computers must be able to confirm they are indeed functioning as intended, even when the devices are remotely accessed. In particular, if the Hilbert space dimension of the components are not as advertised -- for instance if the qubits ...

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

The Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

The Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Mapping species-specific aboveground forest biomass for Guangxi using wall-to-wall airborne laser scanning data

Ecological Indicators
Estimates of aboveground forest biomass (AGB) and carbon fluxes, especially on a species-specific basis, over an extensive area are crucial in decision-making in forestry.

A Statistical Calibration Framework for Improving Non-Reference Method Particulate Matter Reporting: A Focus on Community Air Monitoring Settings

Atmosphere, 2020
Recent advancement in lower-cost air monitoring technology has resulted in an increased interest in community-based air quality studies. However, non-reference monitoring (NRM; e.g., low-cost sensors) is imperfect and approaches that improve data quality

Prospecting of Architectural Features Using LiDAR‐UAV Technology, Deep Neural Networks and Visualization Techniques: A Case Study in Kuélap and Cambolín (NW Peru)

Archaeological Prospection, EarlyView.
ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

Elevation shapes tree composition, structure and diversity more than soil properties in the Annapurna Conservation Area, Nepal

Trees, Forests and People
Despite Nepal's steep elevational gradients and ecological diversity, forest stand dynamics along these gradients remain poorly understood. Therefore, this study aimed to analyze how elevation (1500–4000 m) influences forest properties in the Sikles ...
