Species identity and spatial scale drive context‑dependent tree diversity effects in a Finnish forest experiment

Oikos, EarlyView.
Tree species diversity is known to affect tree growth and leaf traits, which in turn can influence various ecosystem processes. However, the reported direction of these tree diversity effects is inconsistent, indicating that their outcomes depend strongly on ecological context.

Astronomical adaptive optics: a review

PhotoniX
Since the concept of adaptive optics(AO) was proposed in 1953, AO has become an indispensable technology for large aperture ground-based optical telescopes aimed at high resolution observations.

Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

Effect of Adatom Energy on the Interfacial and Surface Morphology of Pulsed DC Sputtered Ruthenium Thin Films

Surface and Interface Analysis, EarlyView.
ABSTRACT In the present study, we have analyzed the growth profile of ruthenium (Ru) thin films, deposited using pulsed direct current (DC) magnetron sputtering technique, by varying the sputtering voltages in the range of 150–420 V. The grazing incidence X‐ray reflectivity (GIXRR), time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS), and atomic ...

Solar Adaptive Optics

Living Reviews in Solar Physics, 2011
Adaptive optics (AO) has become an indispensable tool at ground-based solar telescopes. AO enables the ground-based observer to overcome the adverse effects of atmospheric seeing and obtain diffraction limited observations.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

The SDSS-V Local Volume Mapper Telescope System

The Astronomical Journal
This paper presents the Local Volume Mapper (LVM) telescope system. LVM is one of three surveys that form the fifth generation of the Sloan Digital Sky Survey (SDSS-V), and it employs a coordinated network of four, 16 cm diameter telescopes feeding ...

Hunting regulations and movements of alpine reindeer

Wildlife Biology, EarlyView.
Most ungulate populations are regulated by hunting, and harvest rate is regulated through quotas and hunting season duration. Hunting is well known to affect behaviour of ungulates, but how annual variation in quotas and hunting season duration affects individual behaviour remains uncertain.

Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA

Wildlife Biology, EarlyView.
Dusky grouse Dendragapus obscurus are a montane forest grouse species with a paucity of information regarding their temporal and spatial resource use during critical times of high mortality and reproductive output. This lack of vital data may leave dusky grouse at risk of sub‐optimal management in many areas of their distribution, especially in the ...

YOLO‐GDCNN: Real‐Time Operating Point Detection for Live Working Robots in the Power Industry

High Voltage, EarlyView.
ABSTRACT In the power industry maintenance, the capability of live working robots to detect and operate with power components in real time is paramount. This paper proposes a cascaded detection framework for real‐time detection of live working operation points, named YOLO‐GDCNN. The framework consists of two parts.
