Occupational therapy’s role with ventricular assist devices and the promotion of travel protocols

Natasha Chandra & Linda Suplicki
An option for individuals diagnosed with end-stage heart failure is to receive a ventricular assist device (VAD). In 2006, Shepherd and Wilding produced an article regarding occupational therapy’s role during the VAD process as they anticipated a growing need for this area of practice. Since that time, there continues to be a lack of supporting literature on occupational therapy’s important role with this population. Therefore, the purpose of this article is to explain an occupational...

Information Shocks, Jumps, and Price Discovery - Evidence from the U.S. Treasury Market

George Jiang, Ingrid Lo & Adrien Verdelhan
We examine large price changes, known as jumps, in the U.S. Treasury market. Using recently developed statistical tools, we identify price jumps in the 2-, 3-, 5-, 10-year notes and 30-year bond during the period of 2005-2006. Our results show that jumps mostly occur during prescheduled macroeconomic announcements or events. Nevertheless, market surprise based on preannouncement surveys is an imperfect predictor of bond price jumps. We find that a macroeconomic news announcement is often preceeded...

Historical (1901-1920), contemporary (1979-2013), and future (2061-2080) terrestrial life zones

Paul R. Elsen, Earl C. Saxon, B. Alexander Simmons, Michelle Ward, Brooke A. Williams, Hedley S. Grantham, Salit Kark, Noam Levin, Katharina-Victoria Perez-Hammerle, April E. Reside & James E. M. Watson
Datasets depicting historical (1901-1920), contemporary (1979-2013), and future (2061-2080) life zones as global rasters at 30 arc-second resolution in GeoTiff format are included, which were produced for the study "Accelerated shifts in terrestrial life zones under rapid climate change", published in Global Change Biology by Elsen et al. Life zones are determined by distinct combinations of biotemperature and precipitation and represent broad-scale ecosystem types (sensu Holdridge[1]). For the future period, life zone maps were produced...

Spatiotemporal specificity of correlated DNA methylation and gene expression pairs across different human tissues and stages of brain development

Kangli Wang, Rujia Dai, Yan Xia, Jianghua Tian, Chuan Jiao, Tatiana Mikhailova, Chunling Zhang, Chao Chen & Chunyu Liu
DNA methylation (DNAm) that occurs on promoter regions is primarily considered to repress gene expression. Previous studies indicated that DNAm could also show positive correlations with gene expression. Both DNAm and gene expression profiles are known to be tissue- and development-specific. This study aims to investigate how DNAm and gene expression are coordinated across different human tissues and developmental stages, as well as the biological significance of such correlations. By analyzing 2,239 samples with both...

Worldwide savanna monkey (Chlorocebus spp.) body measures

Christopher A. Schmitt, Trudy R. Turner, Jennifer Danzy Cramer, Joseph Lorenz, J. Paul Grobler, Clifford J. Jolly & Nelson B. Freimer
Objectives: Direct comparative work in morphology and growth on widely dispersed wild primate taxa is rarely accomplished, yet critical to understanding ecogeographic variation, plastic local varia- tion in response to human impacts, and variation in patterns of growth and sexual dimorphism. We investigated population variation in morphology and growth in response to geographic variables (i.e., latitude, altitude), climatic variables (i.e., temperature and rainfall), and human impacts in the vervet monkey (Chlorocebus spp.). Methods: We trapped...

Population assignment tests uncover rare long-distance larval dispersal events

Cassidy D'Aloia, Steven Bogdanowicz, Jose Andres & Peter Buston
Long-distance dispersal (LDD) is consequential to metapopulation ecology and evolution. In systems where dispersal is undertaken by small propagules, such as larvae in the ocean, documenting LDD is especially challenging. Genetic parentage analysis has gained traction as a method for measuring larval dispersal, but such studies are generally spatially limited, leaving LDD understudied in marine species. We addressed this knowledge gap by uncovering LDD with population assignment tests in the coral reef fish Elacatinus lori—a...

Inter- and intra-archipelago dynamics of population structure and gene flow in a Polynesian bird

Ethan Gyllenhaal, Xena Mapel, Tejashree Modak, Lucas DeCicco, Alivereti Naikatini, Ruth Utzurrum, Joshua Seamon, Jean-Claude Thibault, Alice Cibois, Michael Sorenson, Robert Moyle, Lisa Barrow & Michael Andersen
Islands are separated by natural barriers that prevent gene flow between terrestrial populations and promote allopatric diversification. Birds in the South Pacific are an excellent model to explore the interplay between isolation and gene flow due to the region’s numerous archipelagos and well-characterized avian communities. The wattled honeyeater complex (Foulehaio spp.) comprises three allopatric species that are widespread and common across Fiji, Tonga, Samoa, and Wallis and Futuna. Here, we explored patterns of diversification within...

Plant and bird phenology and plant occurrence from 1851 to 2020 (non-continuous) in Thoreau’s Concord, Massachusetts

Elizabeth R. Ellwood, Amanda S. Gallinat, Caitlin McDonough MacKenzie, Tara Miller, Abraham Miller-Rushing, Caroline Polgar & Richard B. Primack
Concord, Massachusetts, USA has served as an active location for phenological observations since philosopher and naturalist Henry David Thoreau began recording plant and animal occurrence and phenology in 1851. Since that time, numerous naturalists, scientists, and researchers have continued this tradition, creating an invaluable time series of 758 species in a single location. A total of 13,441 phenological records, spanning 118 years, now exist, with observations of many species ongoing. Relative abundance data for an...

Adaptive ontogeny in response to ambiguous cues

Julie Jung, James McDaniel & Karen Warkentin
As animals develop, their capacities to sense cues, assess threats, and perform actions change, as do the relative costs and benefits that underlie behavioural decisions. We presented ambiguous cues to test if hatching decisions of red-eyed treefrogs, Agalychnis callidryas, change developmentally following adaptive predictions based on changing costs of decision errors. These arboreal embryos hatch prematurely to escape from egg predators, cued by vibrations in attacks. Young embryos modulate hatching based on frequency and temporal...

Reproductive control via the threat of eviction in the clown anemonefish

Theresa Rueger, Tina Barbasch, Marian Wong, Maya Scrinivasan, Geoffrey Jones & Peter Buston
In social groups, high reproductive skew is predicted to arise when the reproductive output of a group is limited, and dominant individuals can suppress subordinate reproductive efforts. Reproductive suppression is often assumed to occur via overt aggression or the threat of eviction. It is unclear, however, whether the threat of eviction alone is sufficient to induce reproductive restraint by subordinates.Here,we test two assumptions of the restraint model of reproductive skew by investigating whether resource limitation...

Tribolium castaneum defensin 1 kills Moraxella catarrhalisin an in vitro infection model but does not harm commensal bacteria

Wilhelm Bertrams, Nora S. Lindhauer, Marie Christin Rieke, Anne Paas, Kerstin Hoffmann, Brandon Greene, Alexander Visekruna, Andreas Vilcinskas, Kerstin Seidel & Bernd Schmeck
Moraxella catarrhalis is a bacterial pathogen that causes respiratory tract infections in humans. The increasing prevalence of antibiotic-resistant M. catarrhalis strains has created a demand for alternative treatment options. We therefore tested 23 insect antimicrobial peptides (AMPs) for their activity against M. catarrhalis in a human in vitro infection model with primary macrophages, and against commensal bacteria. Effects on bacterial growth were determined by colony counting and growth curve analysis. The inflammatory macrophage response was...

Testing assumptions of nitrogen cycling between a temperate, model coral host and its facultative symbiont: symbiotic contributions to dissolved inorganic nitrogen assimilation

Laura DiRoberts, Alexa Dudek, Nicholas Ray, Robinson Fulweiler & Randi Rotjan
Coral symbioses are predicated on the need for mutual nutrient acquisition and translocation between partners. Carbon translocation is well-studied in this classic mutualism, while nitrogen (N) has received comparatively less attention. Quantifying the mechanisms and dynamics of N assimilation is critical to understanding the functional ecology of coral organisms. Given the importance of symbiosis to the coral holobiont, it is important to determine what role photosynthetic symbionts play in N acquisition. We used the facultatively...

Negotiations Over Parental Care: A Test of Alternative Hypotheses in the Clown Anemonefish

Tina Barbasch, Rebecca Branconi, Robin Francis, Madison Pacaro, Maya Srinivasan, Geoff Jones & Peter Buston
In species with biparental care, conflict arises over how much each parent provides to their offspring because both parents benefit from shifting the burden of care to the other. Here, we tested alternative hypotheses for how parents will negotiate offspring care using a wild population of clownfish (Amphiprion percula). We experimentally handicapped parents by fin-clipping the female in 23 groups, the male in 23 groups, and neither parent in 23 groups and measured changes in...

WaveMAP analysis of extracellular waveforms from monkey premotor cortex during decision-making

Eric Lee, Hymavathy Balasubramanian, Alexandra Tsolias, Stephanie Anakwe, Maria Medalla, Krishna Shenoy & Chandramouli Chandrasekaran
Cortical circuits are thought to contain a large number of cell types that coordinate to produce behavior. Current in vivo methods rely on clustering of specified features of extracellular waveforms to identify putative cell types, but these capture only a small amount of variation. Here, we develop a new method (WaveMAP) that combines non-linear dimensionality reduction with graph clustering to identify putative cell types. We apply WaveMAP to extracellular waveforms recorded from dorsal premotor cortex...

Data from: Hippocampal replay of experience at real-world speeds

Eric Denovellis, Anna Gillespie, Michael Coulter, Marielena Sosa, Jason Chung, Uri Eden & Loren Frank
Representations related to past experiences play a critical role in memory and decision-making processes. The rat hippocampus expresses these types of representations during sharp-wave ripple (SWR) events, and previous work identified a minority of SWRs that contain “replay” of spatial trajectories at ~20x the movement speed of the animal. Efforts to understand replay typically make multiple assumptions about which events to examine and what sorts of representations constitute replay. We therefore lack a clear understanding...

Observations of flowering phenology in Concord, Massachusetts, USA, 1963-1993

Abraham Miller-Rushing, Richard Primack & Elizabeth Ellwood
Phenology plays a vital role in understanding the impacts of climate change on plants. Observing and recording the dates that plants are in flower, over periods of years and decades, can elucidate patterns in how plants respond to warming temperatures, shifting precipitation regimes, and other effects of a changing climate. Long-term records of plant phenology are difficult to find. It is often the case that these records do not originate from scientific research studies but...

Three dimensional localization refinement and motion model parameter estimation for confined single particle tracking under low-light conditions: Simulation datasets

Ye Lin, Fatemeh Sharifi & Sean B. Andersson
The datasets store both motion and observation information of a single fluorescent sub-diffraction limit-sized particle moving in a three-dimensional confined environment. The confined motion is following a nonlinear model driven by non-Gaussian noise, the observation is formed by engineered Double-helix (DH) point spread function (PSF) and captured by scientific complementary metal-oxide semiconductor (sCMOS) camera. Based on our prior computationally efficient application of Sequential Monte Carlo - Expectation Maximization (SMC-EM), we extended it to handle the...

Mechanical MNIST crack path extended version

Saeed Mohammadzadeh & Emma Lejeune
The Mechanical MNIST Crack Path dataset contains Finite Element simulation results from phase-field models of quasi-static brittle fracture in heterogeneous material domains subjected to prescribed loading and boundary conditions. For all samples, the material domain is a square with a side length of 1. There is an initial crack of fixed length (0.25) on the left edge of each domain. The bottom edge of the domain is fixed in x (horizontal) and y (vertical), the...

Expectation maximization based framework for joint localization and parameter estimation in single particle tracking from segmented images - Simulation Data

Ye Lin & Sean B. Andersson
The datasets contain simulated Single Particle Tracking (SPT) data consisting of sequences of camera images of a single fluorescent sub-diffraction limit-sized particle undergoing two-dimensional diffusion. We simulated a variety of experimental conditions, including different Signal-to-Background Ratios (SBRs), two different camera types, different diffusion speeds, and two different settings for motion blur. SPT is a class of experimental methods and data analysis techniques for exploring the motion of individual biological macromolecules. Typical estimation algorithms split the...

Genetic relatedness in social groups of the emerald coral goby Paragobiodon xanthosoma creates potential for weak kin selection

Theresa Rueger, Peter Buston, Steven Bogdanowicz & Marian Wong
The explanation for why animals form social groups that include breeders and non-breeders is an evolutionary puzzle with some parts yet unsolved. Ecological constraints explain why non-breeders do not disperse to breed on their own, while social constraints explain why they do not contest to breed at home. Often kin selection explains why non-breeders behave cooperatively. Originally kin selection was assumed to play no role in social evolution in organisms with dispersive larval phases, such...

Microscale modelling of dielectrophoresis assembly processes

Marco Lauricella, Adriano Tiribocchi, Andrea Montessori, Fabio Bonaccorso, Sauro Succi & Keith A. Brown
This work presents a microscale approach for simulating the dielectrophoresis (DEP) assembly of polarizable particles under an external electric field. The model is shown to capture interesting dynamical and topological features, such as the formation of chains of particles and their incipient aggregation into hierarchical structures. A quantitative characterization in terms of the number and size of these structures is also discussed. This computational model could represent a viable numerical tool to study the mechanical...
