Human pressure, habitat heterogeneity and species traits jointly determine the level of dark diversity in coastal fish communities

open access: yesEcography, EarlyView.
Understanding how anthropogenic pressures and environmental gradients shape coastal fish communities is a central question in biogeography and marine conservation. Yet, the set of species expected to occur at a site given ecological conditions but being absent – the so‐called dark diversity – has received far less attention than observed species, even ...

Count Random Variables

open access: yesEncyclopedia
The observation of randomness patterns serves as guidance for the craft of probabilistic modelling. The most used count models—Binomial, Poisson, Negative Binomial—are the discrete Morris’ natural exponential families whose variance is at most quadratic ...

Modelling Count Data Time Series with Markov Processes Based on Binomial Thinning

open access: yes
We obtain new models and results for count data time series based on binomial thinning. Count data time series may have non-stationarity from trends or covariates, so we propose an extension of stationary time series based on binomial thinning such that ...

Spatio‐temporal dynamics of ringed seal density and habitat use in the Arctic's Last Ice Area

open access: yesEcography, EarlyView.
The Arctic is warming at approximately four times the global rate, driving widespread decline in sea ice extent, thickness, and seasonal duration. The ecological consequences of these rapid changes remain poorly understood within the Last Ice Area, a region that includes northern Ellesmere Island and the northwest of Greenland, projected to retain ...

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

open access: yesGeological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Twelve‐Month Outcomes of a Preventive Dysphagia Intervention in Patients With Head and Neck Cancer—A Randomized Study

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Radiation‐associated dysphagia is common after radiotherapy for head and neck cancer and may occur early or years later. The effect of preventive exercises might be undermined by poor adherence. Aim To evaluate the effect of a simple preventive exercise protocol on swallowing function up to 12 months after radiotherapy.

Stationary Underdispersed INAR(1) Models based on the Backward Approach

open access: yesRevstat Statistical Journal
Most of the stationary first-order autoregressive integer-valued (INAR(1)) models in the literature have been developed using the idea of binomial thinning. Two approaches have been adopted to establish the distributional properties of a stationary INAR(

Clinicoepidemiologic Profile of Oral Kaposi Sarcoma in People Living With HIV: A Systematic Review and Meta‐Analysis

open access: yesHead &Neck, EarlyView.
ABSTRACT Background To characterize the clinicoepidemiologic profile of HIV‐associated oral Kaposi sarcoma (OKS) and quantitatively synthesize its frequency, anatomical distribution, and temporal patterns across antiretroviral therapy (ART) eras. Methods Six databases and gray literature were searched.

Double‐VISTA technique with connective tissue graft or acellular dermal matrix for treating multiple recessions associated with non‐carious cervical lesions: A retrospective study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This retrospective study evaluated whether clinical outcomes differed between connective tissue graft (CTG) and allogeneic solvent‐dehydrated acellular dermal matrix (ADM) for treating multiple gingival recessions associated with non‐carious cervical lesions (NCCLs) using partial restoration and the double‐vestibular incision ...
