MeerKAT 1.3 GHz Observations of Supernova Remnants

open access: yesThe Astrophysical Journal Supplement Series
We present full Stokes MeerKAT L -band (856–1712 MHz) observations of 36 high-latitude supernova remnants (SNRs). Sensitive, high-dynamic-range images show a wealth of structure. G15.1−1.6 appears to be a H ii region rather than an SNR.

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

open access: yesIntegrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

Prey Partitioning in a Diverse Carnivore Community: Implications for Reintroduced Fishers in Washington

open access: yesAnimal Conservation, EarlyView.
Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...

Blind FIR Channel Estimation in the Presence of Unknown Noise [PDF]

open access: yes, 2005
In this thesis, we present three algorithms for blind estimation of the finite impulse response (FIR) channels in the presence of unknown noise. The algorithms are developed considering different available system resources: 1) If only one receiving ...

Weekend Overload: Day‐to‐Day Fluctuations of Outdoor Recreation Affect Wild Mammals' Space‐Use in a Popular Forest Reserve Near Florence, Italy

open access: yesAnimal Conservation, EarlyView.
In an urban‐adjacent forested area, we investigated the spatial and temporal distribution of the wild mammal community in relation to day‐to‐day fluctuations of human presence occurring between working days and weekends. We deployed 52 camera‐traps systematically within an EU Natura 2000 area located within the metropolitan area of Florence, central ...

Sanitation felling against the European spruce bark beetle: A matter of intensity and forest type Tagli fitosanitari contro il bostrico tipografo: una questione di intensità e tipologia forestale

open access: yesAgricultural and Forest Entomology, EarlyView.
We assess the effect of sanitation felling performed in 2022 in North‐Eastern Italy on bark beetle damage that occurred in 2023 across eight spruce forest types, as evaluated using multispectral satellite imagery. Bark beetle damage was reduced only at very high or very low sanitation felling rates.

Intercooperation and open innovation: Unleashing cooperative firms’ innovation potential

open access: yesAnnals of Public and Cooperative Economics, EarlyView.
Abstract This research examines how interorganizational cooperation impacts the innovation performance of cooperative firms. Existing literature asserts that there are limitations in the innovation capabilities of cooperatives. This study seeks to challenge that assumption and explore whether the nature of such firms enhances their cooperation with ...

Active surveillance for intermediate risk prostate cancer: the Manitoba Prostate Center experience

open access: yesBJU International, EarlyView.
Objectives To report long‐term oncological outcomes of men with intermediate‐risk prostate cancer managed with active surveillance at a single centre. Subjects/Patients and Methods We retrospectively analysed a prospectively maintained Manitoba Prostate Centre active surveillance database.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

open access: yesBoreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...
