Loneliness is not associated with attention interference of negative social information: Evidence from four studies Open
Extended experiences of loneliness, defined as perceived social isolation, are associated with lasting impacts on health outcomes. One proposed mechanism through which loneliness contributes to health risk is heightened vigilance to cues o…
Biomolecular correlates of incubated sucrose-seeking within ventromedial prefrontal cortex are sex- and subregion-selective Open
The similar temporal profile of incubated food- vs. drug-craving has led to the hypothesis that these behavioral phenomena may involve common, time-dependent, biochemical adaptations within neural circuits governing motivated behavior. Pre…
Loneliness Is Associated With Decreased Support and Increased Strain Given in Social Relationships Open
Prolonged loneliness can be detrimental to both mental and physical health. However, variability in how individuals respond to loneliness can shape health outcomes. Here, we explored whether loneliness is related to perceptions of support …
Some Algebras With Trivial Rings of Differential Operators Open
Let $k$ be an arbitrary field. We construct examples of regular local $k$-algebras $R$ (of positive dimension) for which the ring of differential operators $D_{k}(R)$ is trivial in the sense that it contains no operators of positive order.…
White-Knuckled Prosociality: Loneliness increases willingness to exert effort to benefit others Open
Loneliness, or perceived social isolation, motivates individuals to foster their relationships while remaining vigilant to potential social threats. Lonely individuals must interpret the social cues they receive from others and respond acc…
Instability in the environment and children’s in-school self-regulatory behaviors Open
Introduction Experiences of chronic and/or extreme stress early in childhood are associated with altered self-regulatory behaviors. However, there is a range of variability in children’s behavioral outcomes after experiences of stress. Und…
How does loneliness impact emotion perception? A systematic review Open
Loneliness, or perceived social isolation, is linked to significant long-term consequences for health. One mechanism through which loneliness contributes to health risk is via shifts in social cognition, particularly increased vigilance fo…
Some algebras with trivial rings of differential operators Open
Let $k$ be an arbitrary field. We construct examples of regular local $k$-algebras $R$ (of positive dimension) for which the ring of differential operators $D_k(R)$ is trivial in the sense that it contains {\it no} operators of positive or…
Resting parasympathetic activity is associated with malodor‐induced change in perceived foreignness of speakers Open
Introduction To protect against infection, individuals have evolved context‐dependent pathogen‐avoidant strategies, including selective social behaviors aimed at avoiding foreign individuals who may possess greater risk of infection. Paras…
Ambiguity potentiates effects of loneliness on feelings of rejection Open
For social species, having strong and high-quality social relationships is an important safety cue. Loneliness occurs when an individual perceives they have insufficient relationships resulting in feelings of lack of safety. States of perc…
Values of the <i>F</i>‐pure threshold for homogeneous polynomials Open
We find a formula, in terms of , and , for the value of the ‐pure threshold for the generic homogeneous polynomial of degree in variables over an algebraically closed field of characteristic . We also show that in every characteristic and …
Somatovisceral Influences on Emotional Development Open
Frameworks of emotional development have tended to focus on how environmental factors shape children's emotion understanding. However, individual experiences of emotion represent a complex interplay between both external environmental inpu…
Lower bounds on the F-pure threshold and extremal singularities Open
We prove that if is a reduced homogeneous polynomial of degree , then its -pure threshold at the unique homogeneous maximal ideal is at least . We show, furthermore, that its -pure threshold equals if and only if and , where is a power of …
Values of the F-pure threshold for homogeneous polynomials Open
We find a formula, in terms of n, d and p, for the value of the F-pure threshold for the generic homogeneous polynomial of degree d in n variables over an algebraically closed field of characteristic p. We also show that, in every characte…
Approach motivation and loneliness: Individual differences and parasympathetic activity Open
Loneliness, or perceived social isolation, is linked to a number of negative long‐term effects on both mental and physical health. However, how an individual responds to feeling lonely may influence their risk for later negative health out…
Early life stress and perceived social isolation influence how children use value information to guide behavior Open
Learning the value of environmental signals and using that information to guide behavior is critical for survival. Stress in childhood may influence these processes, but how it does so is still unclear. This study examined how stressful ev…
Vaccine Search Patterns Provide Insights into Vaccination Intent Open
Despite ample supply of COVID-19 vaccines, the proportion of fully vaccinated individuals remains suboptimal across much of the US. Rapid vaccination of additional people will prevent new infections among both the unvaccinated and the vacc…
Geometry of Smooth Extremal Surfaces Open
We study the geometry of the smooth projective surfaces that are defined by Frobenius forms, a class of homogenous polynomials in prime characteristic recently shown to have minimal possible F-pure threshold among forms of the same degree.…
Thinking Clearly About Biology and Childhood Adversity: Next Steps for Continued Progress Open
In a previous Perspectives article, we described conceptual problems that pose challenges for research on the effects of childhood adversity and offered promising directions for future research on this topic. In a commentary on that articl…
Social relationships and children’s perceptions of adversity Open
Having sensitive, contingent, and supportive social relationships has been linked to more positive outcomes after experiences of early childhood adversity. Traditionally, social relationships are construed as moderators that buffer childre…
Odour Learning Bees Have Longer Foraging Careers Than Non-learners in a Natural Environment Open
Individual animals allowed the opportunity to learn generally outperform those prevented from learning, yet, within a species the capacity for learning varies markedly. The evolutionary processes that maintain this variation in learning ab…
Cubic surfaces of characteristic two Open
Cubic surfaces in characteristic two are investigated from the point of view of prime characteristic commutative algebra. In particular, we prove that the non-Frobenius split cubic surfaces form a linear subspace of codimension four in the…
Classification of Frobenius Forms in five variables Open
We classify Frobenius forms, a special class of homogeneous polynomials in characteristic $p>0$, in up to five variables over an algebraically closed field. We also point out some of the similarities with quadratic forms.
