Efficient learning of quantum noise

Robin Harper, Steven Flammia & Joel Wallman
Noise is the central obstacle to building large-scale quantum computers. Quantum systems with sufficiently uncorrelated and weak noise could be used to solve computational problems that are intractable with current digital computers. There has been substantial progress towards engineering such systems. However, continued progress depends on the ability to characterize quantum noise reliably and efficiently with high precision. Here we introduce a protocol that comprehensively and efficiently characterizes the error rates of quantum noise and...

Supporting data to: Evolution of realized Eltonian niches across Rajidae species

Oliver Shipley, Joseph Kelly, Joseph Bizzarro, Jill Olin, Robert Cerrato, Michael Power & Michael Frisk
The notion that closely related species resemble each other in ecological niche space (i.e., phylogenetic dependence) has been a longstanding, contentious paradigm in evolutionary biology, the incidence of which is important for predicting the ecosystem-level effects of species loss. Despite being examined across a multitude of terrestrial taxa, many aspects of niche conservatism have yet to be explored in marine species, especially for characteristics related to resource use and trophic behavior (Eltonian niche characteristics, ENCs)....

Data from: Diverse and complex muscle spindle afferent firing properties emerge from multiscale muscle mechanics

Kyle Blum, Brian Horslen, Kenneth Campbell, Brian Horslen, Paul Nardelli, Stephen Housley, Timothy Cope & Lena Ting
Despite decades of research, we lack a mechanistic framework capable of predicting how movement-related signals are transformed into the diversity of muscle spindle afferent firing patterns observed experimentally, particularly in naturalistic behaviors. Here, a biophysical model demonstrates that well-known firing characteristics of mammalian muscle spindle Ia afferents – including movement history dependence, and nonlinear scaling with muscle stretch velocity – emerge from first principles of muscle contractile mechanics. Further, mechanical interactions of the muscle spindle...

The Loss of Playfulness

Janet Jones
How does social distancing affect our sense of self? Our ability to create ourselves? In this article, I explore the value of interacting with strangers for our sense of self and the impact of COVID-19 safety measures on our relationships with others. Specifically, I suggest that strangers can offer us opportunities to try on new identities but that this opportunity is lost as the public realm erodes because of the COVID-19 pandemic.

Analytic dataset informing prediction of subterranean cave and mine ambient temperatures

Meredith McClure, Daniel Crowley, Catherine Haase, Liam McGuire, Nathan Fuller, David Hayman, Cori Lausen, Raina Plowright, Brett Dickson & Sarah Olson
Caves and other subterranean features provide unique environments for many species. The importance of cave microclimate is particularly relevant at temperate latitudes where bats make seasonal use of caves for hibernation. White-nose syndrome (WNS), a fungal disease that has devastated populations of hibernating bats across eastern and central North America, has brought renewed interest in bat hibernation and hibernaculum conditions. A recent review synthesized current understanding of cave climatology, exploring the qualitative relationship between cave...

Data from: Down by the riverside: Riparian edge effects on three monkey species in a fragmented Costa Rican forest

Laura Bolt, Amy Schreier, Kristofor Voss, Elizabeth Sheehan & Nancy Barrickman
Rivers represent natural edges in forests, serving as transition zones between landscapes. Natural edge effects are important to study to understand how intrinsic habitat variations affect wildlife as well as the impact of human-induced forest fragmentation. We examined the influence of riparian and anthropogenic edge on mantled howler, white-faced capuchin, Central American spider monkeys, and vegetation structure at La Suerte Biological Research Station (abbreviated as LSBRS), Costa Rica. We predicted lower monkey encounter rate, tree...

Disentangling interactions among mercury, immunity, and infection in a Neotropical bat community

Daniel Becker, Kelly Speer, Jennifer Korstian, Dmitriy Volokhov, Hannah Droke, Alexis Brown, Catherene Baijnauth, Ticha Padgett-Stewart, Hugh Broders, Raina Plowright, Thomas Rainwater, Brock Fenton, Nancy Simmons & Matthew Chumchal
Contaminants such as mercury are pervasive and can have immunosuppressive effects on wildlife. Impaired immunity could be important for forecasting pathogen spillover risks, as many land-use changes that generate mercury contamination also bring wildlife into close contact with humans and domestic animals. However, the interactions among contaminants, immunity, and infection are difficult to study in natural systems, and empirical tests of possible directional relationships remain rare. We capitalized on extreme mercury variation in a diverse...

Tactic-specific antimicrobial activity suggests a parental care function for accessory glands in a marine toadfish

Meghan Pepler, Hindra Hindra, Jessica Miller, Marie Elliot & Sigal Balshine
Males of some species possess extra reproductive organs called accessory glands which are outgrowths of the testes or sperm duct. These organs have a well-established role in reproduction; however, they also appear to have other important functions that are less understood. Here we investigate the function of the highly complex accessory glands of a marine toadfish, Porichthys notatus, a fish with two reproductive male types: large care-providing ‘guarder’ males and small non-caring ‘sneaker’ males. While...
