Twin neural network regression

Applied AI Letters, Volume 3, Issue 4, December 2022., 2022
We propose to reformulate a regression problem into predicting differences between target values. This allows for leveraging consistency conditions which can be used as uncertainty estimates and enable the production of an ensemble of predictions while training only a single neural network.

Response of riparian vegetation to short‐ and long‐term hydrologic variation

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract Increasing demand for river water now conflicts with an increasing desire to maintain riparian ecosystems. Efficiently managing river flows for riparian vegetation requires an understanding of the time scale of flow effects, but this information is limited by the absence of long‐term studies of vegetation change in response to flow variation ...

Modeling net ecosystem carbon balance and loss in coastal wetlands exposed to sea‐level rise and saltwater intrusion

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract Coastal wetlands are globally important stores of carbon (C). However, accelerated sea‐level rise (SLR), increased saltwater intrusion, and modified freshwater discharge can contribute to the collapse of peat marshes, converting coastal peatlands into open water.

Predation thresholds for reintroduction of native avifauna following suppression of invasive Brown Treesnakes on Guam

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract The brown treesnake (BTS) (Boiga irregularis) invasion on Guåhan (in English, Guam) led to the extirpation of nearly all native forest birds. In recent years, methods have been developed to reduce BTS abundance on a landscape scale. To help assess the prospects for the successful reintroduction of native birds to Guåhan following BTS ...

Moments of Askey-Wilson polynomials [PDF]

Discrete Mathematics & Theoretical Computer Science, 2013
New formulas for the $n^{\mathrm{th}}$ moment $\mu_n(a,b,c,d;q)$ of the Askey-Wilson polynomials are given. These are derived using analytic techniques, and by considering three combinatorial models for the moments: Motzkin paths, matchings, and ...

Positive, complicated, distant, and negative: How different teacher‐student relationship profiles relate to students’ science motivation

Journal of Adolescence, Volume 94, Issue 8, Page 1150-1162, December 2022., 2022
Abstract Introduction Researchers note a consistent decline in adolescents’ motivation and participation in science. It is important to examine factors vital to students’ motivation in science, such as teacher‐student relationships (TSRs). Limited research in science has examined TSRs from a multidimensional or person‐centered perspective.

Three‐dimensional swimming behavior and activity of a mesopelagic fish

Limnology and Oceanography, Volume 67, Issue 12, Page 2677-2690, December 2022., 2022
Abstract Knowledge of the three‐dimensional behavior and activity patterns of mesopelagic fishes is crucial for understanding their role in ecological and biogeochemical processes in the ocean. We here show that the use of submerged stationary echosounders enables detailed analysis of three‐dimensional swimming behavior of small mesopelagic fishes in ...

Change in climatically suitable breeding distributions reduces hybridization potential between Vermivora warblers

Diversity and Distributions, Volume 29, Issue 2, Page 254-271, February 2023., 2023
Abstract Aim Climate change is affecting the distribution of species and subsequent biotic interactions, including hybridization potential. The imperiled Golden‐winged Warbler (GWWA) competes and hybridizes with the Blue‐winged Warbler (BWWA), which may threaten the persistence of GWWA due to introgression.

Properties of the є-expansion, Lagrange inversion and associahedra and the O (1) model

Journal of High Energy Physics, 2020
We discuss properties of the є-expansion in d = 4 − є dimensions. Using Lagrange inversion we write down an exact expression for the value of the Wilson-Fisher fixed point coupling order by order in є in terms of the beta function coefficients.

Defect and degree of the Alexander polynomial

European Physical Journal C: Particles and Fields, 2022
Defect characterizes the depth of factorization of terms in differential (cyclotomic) expansions of knot polynomials, i.e. of the non-perturbative Wilson averages in the Chern-Simons theory.
