Impacts of nature deprivations during the COVID-19 pandemic: A pre-post comparison [PDF]

open access: yesarXiv, 2023
Nature provides a myriad of intangible and non-material services to people. However, urbanites are increasingly disconnected from the natural world. The consequences of this progressive disconnection from nature remain difficult to measure as this process is slow and long-term monitoring or large-scale manipulation on nature experiences are scarce ...

Population and species neighbor identity impact trait–trait relationships and plant performance

open access: yesPopulation Ecology, EarlyView.
We evaluated how populations and species identity influence plant performance and trait outcomes in mixtures, and assessed trait variation among populations of two forb species native to the western United States (Dieteria canescens and Heterotheca villosa) following three interaction treatments (single‐population monoculture, two‐population mixture ...

Dirichlet is Natural [PDF]

open access: yesElectronic Notes in Theoretical Computer Science, 2015
AbstractGiry and Lawvere's categorical treatment of probabilities, based on the probabilistic monad G, offer an elegant and hitherto unexploited treatment of higher-order probabilities. The goal of this paper is to follow this formulation to reconstruct a family of higher-order probabilities known as the Dirichlet process. This family is widely used in

The dual nature of TDC – bridging dendritic and T cells in immunity

open access: yesFEBS Letters, EarlyView.
TDC are hematopoietic cells combining dendritic and T cell features. They reach secondary lymphoid organs (SLOs) and peripheral organs (liver and lungs) after FLT3‐dependent development in the bone marrow and maturation in the thymus. TDC are activated and enriched in SLOs upon viral infection, suggesting that they might play unique immune roles, since

Assessment of Road Crossings for Improving Migratory Fish Passage in the Winnicut River Watershed [PDF]

open access: yes, 2009
This report summarizes the results of a river continuity assessment focused on roadstream crossings. The Winnicut River is the site of a restoration project that removed a head-of-tide dam and resulted in the only free-flowing major tributary to the ...

The nature and ethics of natural experiments [PDF]

open access: yesJournal of Medical Ethics, 2015
Natural experiments are an important methodology often used to answer research questions that would, otherwise, be impossible to address, or employed because of ethical concerns about the use of randomisation to interventions that carry known risks.

FoxO1 signaling in B cell malignancies and its therapeutic targeting

open access: yesFEBS Letters, EarlyView.
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

Naturalness Evaluation of Natural Language Generation in Task-oriented Dialogues using BERT [PDF]

open access: yesarXiv, 2021
This paper presents an automatic method to evaluate the naturalness of natural language generation in dialogue systems. While this task was previously rendered through expensive and time-consuming human labor, we present this novel task of automatic naturalness evaluation of generated language.

Natural Disaster and Natural Selection [PDF]

open access: yesSSRN Electronic Journal, 2013
In this paper, we investigate whether a natural selection mechanism works for firm exit. By using data of firms after a devastating earthquake, the Great Tohoku Earthquake, we examine the impact of firm efficiency on firm exit both inside and outside the earthquake-affected areas. We find evidence suggesting that more efficient firms are less likely to
