Discharge and nutrients interact to determine trophic structure in a wetland: Evidence from a landscape‐scale manipulation

open access: yesLimnology and Oceanography, EarlyView.
Abstract Identifying drivers of consumer biomass patterns and community structure is complex for managed freshwater ecosystems that are sensitive to nutrients and drought. In the Florida Everglades, flow restoration is expected to reintroduce discharge across an expansive wetland, yet most research on consumers has focused on water depth and dry ...

A Step‐by‐Step Workflow for Performing In Silico Clinical Trials With Nonlinear Mixed Effects Models

open access: yesCPT: Pharmacometrics &Systems Pharmacology, EarlyView.
ABSTRACT In silico clinical trials (ISCT) are computational frameworks that employ mathematical models to generate virtual patients and simulate their responses to new treatments, treatment regimens, or medical devices via simulations mirroring real‐world clinical trials.

Divisibility of binomial coefficients by powers of two

open access: yes, 2017
For nonnegative integers $j$ and $n$ let $\Theta(j,n)$ be the number of entries in the $n$-th row of Pascal's triangle that are not divisible by $2^{j+1}$. In this paper we prove that the family $j\mapsto\Theta(j,n)$ usually follows a normal distribution.

Statistical Complexity of Quantum Learning

open access: yesAdvanced Quantum Technologies, EarlyView.
The statistical performance of quantum learning is investigated as a function of the number of training data N$N$, and of the number of copies available for each quantum state in the training and testing data sets, respectively S$S$ and V$V$. Indeed, the biggest difference in quantum learning comes from the destructive nature of quantum measurements ...

Nitrogen enrichment promotes isopods through reduced carbon and nitrogen stoichiometric mismatch with understorey plants

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract As key detritivores and fungal grazers, terrestrial isopods (Isopoda: Oniscidea) play crucial roles in mediating ecosystem processes. Although nitrogen enrichment represents a major global change driver known to modify soil food webs, its long‐term effects on the ...

Complex effects of climatic variation on bumblebee queen fitness

open access: yesJournal of Animal Ecology, EarlyView.
A dearth of data on the health of wild‐insect populations hinders efforts to fully grasp the extent of historical population declines or unravel the mechanisms driving these effects. We help fill this data deficit by testing how climatic variation affects health, reproduction, size and survival in bumblebees—important insect pollinators.
