Effects of Partner Workload and Increasing Environmental Temperature on Nestling Provisioning and Body Temperature in a Declining Aerial Insectivore

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT With climate change, birds will face increasing thermoregulatory demands, which may alter reproductive behaviors such as offspring provisioning. Experimental studies have shown that the provisioning capacity of female tree swallows (Tachycineta bicolor) is limited by their risk of overheating. Given that parental investment strategies may vary

Structure‐Aware Machine Learning for Polymers: A Hierarchical Graph Network for Predicting Properties From Statistical Ensembles

open access: yesMacromolecular Rapid Communications, EarlyView.
This work presents a structure‐aware graph convolutional network that models polymers as statistical ensembles to predict macroscopic properties. By combining topologically realistic graphs generated via kinetic Monte Carlo simulations with explicit molar mass distributions, the framework achieves high accuracy in classifying architectures and ...

Infinite flags and Schubert polynomials

open access: yesForum of Mathematics, Sigma
We study Schubert polynomials using geometry of infinite-dimensional flag varieties and degeneracy loci. Applications include Graham-positivity of coefficients appearing in equivariant coproduct formulas and expansions of back-stable and enriched ...

Wandering Motive and Its Appeal on Reluctantly Wandering Franz Schubert

open access: yesEtnoantropološki Problemi, 2016
Franz Schubert was not generous in commenting his own creative procedures, or in revealing his artistic inspirations. Therefore, it is even today not clear why Wilhelm Müller’s collection of poems entitled Winter journey attracted Schubert so strongly ...

The special Schubert calculus is real

open access: yes, 1998
We show that the Schubert calculus of enumerative geometry is real, for special Schubert conditions. That is, for any such enumerative problem, there exist real conditions for which all the a priori complex solutions are real.Comment: 5 ...

Osmolality of fortified human milk with contemporary human milk fortifiers

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Human milk fortification is critical to support preterm infant growth. Human milk fortifed to caloric densities above manufacturers’ recommendations are often necessary to achieve adequate growth. Fortified milk may be prepared 12–24 h before feeding, although practice variations exist.

Linking Environmental Health and Civic Health: An Analysis of Air Pollution and Charitable Giving

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT This study examines the effect of air pollution on charitable giving. We suggest that the burdens associated with poor air quality are associated with a dampening of civic and philanthropic engagement. Analyzing 12 years of county‐level data from the United States with fixed‐effects OLS and instrumental variables regressions, we identify a ...

Partial recovery of large seed arrival following ecological restoration in fragmented tropical rainforests

open access: yesOikos, EarlyView.
Forest restoration success depends crucially on the reinitiation of ecological processes such as seed arrival that drive natural regeneration. We know little about whether, by increasing and diversifying local seed sources to alleviate seed limitation, and attracting animal frugivores to alleviate dispersal limitation, restoration could shift seed ...
