The Impact

For many years, food engineers have attempted to describe physical phenomena such as heat and mass transfer in food via mathematical models. Still, the impact and benefits of computer-aided engineering are less established in food than in most other industries today. Complexity in the structure and composition of food matrices are largely responsible for this gap. During processing of food, its temperature, moisture, and structure can change continuously, along with its physical properties. We summarize the knowledge foundation, recent progress, and remaining limitations in modeling food particle systems in four relevant areas: flowability, size reduction, drying, and granulation and agglomeration. Our goal is to enable researchers in academia and industry dealing with food powders to identify approaches to address their challenges with adequate model systems or through structural and compositional simplifications. With advances in computer simulation capacity, detailed particle-scale models are now available for many applications. Here, we discuss aspects that require further attention, especially related to physics-based contact models for discrete-element models of food particle systems.

The Impact

The Department of Justice's pattern-or-practice police reform program has been an unprecedented event in American policing, intervening in local and state law enforcement agencies as never before and requiring a sweeping package of reforms. The program has reached reform settlements with forty agencies, including twenty with judicially enforced consent decrees. Academic research on the program, however, has been fairly modest. Social scientists have largely focused on a few selected issues. There is no study of the full impact of the program on one agency, and there is no comprehensive study of the impact of the program as a whole. Evaluations of individual agencies have been generally favorable, although with backsliding in some agencies. This review argues that the combination of several major goals and the various elements of specific consent decree reforms have created a web of accountability that is unmatched by any previous police reform effort.

Highly Virulent

Ancient enzootic associations between wildlife and their infections allow evolution to innovate mechanisms of pathogenicity that are counterbalanced by host responses. However, erosion of barriers to pathogen dispersal by globalization leads to the infection of hosts that have not evolved effective resistance and the emergence of highly virulent infections. Global amphibian declines driven by the rise of chytrid fungi and chytridiomycosis are emblematic of emerging infections. Here, we review how modern biological methods have been used to understand the adaptations and counteradaptations that these fungi and their amphibian hosts have evolved. We explore the interplay of biotic and abiotic factors that modify the virulence of these infections and dissect the complexity of this disease system. We highlight progress that has led to insights into how we might in the future lessen the impact of these emerging infections.

We reassess progress in the field of biomolecular modeling and simulation, following up on our perspective published in 2011. By reviewing metrics for the field's productivity and providing examples of success, we underscore the productive phase of the field, whose short-term expectations were overestimated and long-term effects underestimated. Such successes include prediction of structures and mechanisms; generation of new insights into biomolecular activity; and thriving collaborations between modeling and experimentation, including experiments driven by modeling. We also discuss the impact of field exercises and web games on the field's progress. Overall, we note tremendous success by the biomolecular modeling community in utilization of computer power; improvement in force fields; and development and application of new algorithms, notably machine learning and artificial intelligence. The combined advances are enhancing the accuracy and scope of modeling and simulation, establishing an exemplary discipline where experiment and theory or simulations are full partners.

Liquid Liquid Phase Separation

Lateral organization in the plane of the plasma membrane is an important driver of biological processes. The past dozen years have seen increasing experimental support for the notion that lipid organization plays an important role in modulating this heterogeneity. Various biophysical mechanisms rooted in the concept of liquid–liquid phase separation have been proposed to explain diverse experimental observations of heterogeneity in model and cell membranes with distinct but overlapping applicability. In this review, we focus on the evidence for and the consequences of the hypothesis that the plasma membrane is poised near an equilibrium miscibility critical point. Critical phenomena explain certain features of the heterogeneity observed in cells and model systems but also go beyond heterogeneity to predict other interesting phenomena, including responses to perturbations in membrane composition.

This article reviews existing research on board diversity. What role does diversity of board members play in board governance, and how does it influence firm behavior and firm value? First, given the recent focus on board diversity among institutional investors and regulators, we present stylized facts and time trends in board diversity. Second, we discuss the dimensions of diversity that have been examined in the literature. Third, we study the determinants of board diversity. Finally, we assess the research on the effects of board diversity on firm performance and outcomes. We discuss the endogeneity challenges of studying the impact of diversity on firm value and review the main approaches that existing studies have used to address endogeneity. We conclude with suggestions for future research on board diversity. Expected final online publication date for the Annual Review of Financial Economics, Volume 13 is March 2021.

Diet and nutrition are intricately related to cancer prevention, growth, and treatment response. Preclinical rodent models are a cornerstone to biomedical research and remain instrumental in our understanding of the relationship between cancer and diet and in the development of effective therapeutics. However, the success rate of translating promising findings from the bench to the bedside is suboptimal. Well-designed rodent models will be crucial to improving the impact basic science has on clinical treatment options. This review discusses essential experimental factors to consider when designing a preclinical cancer model with an emphasis on incorporating these models into studies interrogating diet, nutrition, and metabolism. The aims of this review are to ( a) provide insight into relevant considerations when designing cancer models for obesity, nutrition, and metabolism research; ( b) identify common pitfalls when selecting a rodent model; and ( c) discuss strengths and limitations of available preclinical models.

Brain–machine interfaces (BMIs) promise to restore movement and communication in people with paralysis and ultimately allow the human brain to interact seamlessly with external devices, paving the way for a new wave of medical and consumer technology. However, neural activity can adapt and change over time, presenting a substantial challenge for reliable BMI implementation. Large-scale recordings in animal studies now allow us to study how behavioral information is distributed in multiple brain areas, and state-of-the-art interfaces now incorporate models of the brain as a feedback controller. Ongoing research aims to understand the impact of neural plasticity on BMIs and find ways to leverage learning while accommodating unexpected changes in the neural code. We review the current state of experimental and clinical BMI research, focusing on what we know about the neural code, methods for optimizing decoders for closed-loop control, and emerging strategies for addressing neural plasticity.

The Impact

Despite their enormous potential impact on population health and health inequities, police violence and use of excessive force have only recently been addressed from a public health perspective. Moving to change this state of affairs, this article considers police violence in the USA within a social determinants and health disparities framework, highlighting recent literature linking this exposure to mental health symptoms, physical health conditions, and premature mortality. The review demonstrates that police violence is common in the USA; is disproportionately directed toward Black, Latinx, and other marginalized communities; and exerts a significant and adverse effect on a broad range of health outcomes. The state-sponsored nature of police violence, its embedding within a historical and contemporary context of structural racism, and the unique circumstances of the exposure itself make it an especially salient and impactful form of violence exposure, both overlapping with and distinct from other forms of violence. We conclude by noting potential solutions that clinicaly psychology and allied fields may offer to alleviate the impact of police violence, while simultaneously recognizing that a true solution to this issue requires a drastic reformation or replacement of the criminal justice system, as well as addressing the broader context of structural and systemic racism in the USA.

Whether there are common features inherent to the psychology of Indigenous peoples around the globe has been the subject of much debate. We argue that Indigenous peoples share the experience of colonization and its social and psychological consequences. We develop this argument across four sections: ( a) the global history of colonization and social inequalities; ( b) aspects concerning identity and group processes, including the intergenerational transmission of shared values, the connection with nature, and the promotion of social change; ( c) prejudice and discrimination toward Indigenous peoples and the role of psychological processes to improve relations between Indigenous and non-Indigenous peoples; and ( d) the impact of historical trauma and colonialism on dimensions including cognition, mental health, and the well-being of Indigenous peoples as well as the basis for successful interventions that integrate Indigenous knowledge. Finally, we address future challenges for research on these topics. Expected final online publication date for the Annual Review of Psychology, Volume 73 is January 2022.

Imperfect medication adherence remains the biggest predictor of treatment failure for patients with tuberculosis. Missed doses during treatment lead to relapse, tuberculosis resistance, and further spread of disease. Understanding individual patient phenotypes, population pharmacokinetics, resistance development, drug distribution to tuberculosis lesions, and pharmacodynamics at the site of infection is necessary to fully measure the impact of adherence on patient outcomes. To decrease the impact of expected variability in drug intake on tuberculosis outcomes, an improvement in patient adherence and new forgiving regimens that protect against missed doses are needed. In this review, we summarize emerging technologies to improve medication adherence in clinical practice and provide suggestions on how digital adherence technologies can be incorporated in clinical trials and practice and the drug development pipeline that will lead to more forgiving regimens and benefit patients suffering from tuberculosis.
