Contrastive Similarity Matching for Supervised Learning.

Neural Comput 2021 Feb 22:1-29. Epub 2021 Feb 22.

John A. Paulson School of Engineering and Applied Sciences, Harvard University, Cambridge, MA 02138, U.S.A.

We propose a novel biologically plausible solution to the credit assignment problem motivated by observations in the ventral visual pathway and trained deep neural networks. In both, representations of objects in the same category become progressively more similar, while objects belonging to different categories become less similar. We use this observation to motivate a layer-specific learning goal in a deep network: each layer aims to learn a representational similarity matrix that interpolates between previous and later layers.

Strong spatial embedding of social networks generates nonstandard epidemic dynamics independent of degree distribution and clustering.

Proc Natl Acad Sci U S A 2020 09 8;117(38):23636-23642. Epub 2020 Sep 8.

Medical Research Council Centre for Global Infectious Disease Analysis, Department of Infectious Disease Epidemiology, School of Public Health, Imperial College London, London W2 1PG, United Kingdom;

Some directly transmitted human pathogens, such as influenza and measles, generate sustained exponential growth in incidence and have a high peak incidence consistent with the rapid depletion of susceptible individuals. Many do not. While a prolonged exponential phase typically arises in traditional disease-dynamic models, current quantitative descriptions of nonstandard epidemic profiles are either abstract, phenomenological, or rely on highly skewed offspring distributions in network models.

Why Teachers and Learners of Medicine Need Portraiture.

AMA J Ethics 2020 06 1;22(6):E499-504. Epub 2020 Jun 1.

Vice president of medical affairs and chief medical officer of Methodist Hospital in Omaha, Nebraska.

Medical and especially surgical teaching stresses the importance of careful observation, developing tolerance for ambiguity, and cultivating empathy for patients' and colleagues' experiences of receiving and giving health care. Portraiture is defined by portraitist Mark Gilbert as a collaborative process between subject and artist; sitting is as critical to this process as painting or drawing. This article draws upon the second author's work with Gilbert to examine how portraiture can motivate key teaching and learning goals in health professions education by facilitating learners' explorations of their own and others' biases, limitations, and approaches to gathering information from and about a source (eg, a subject or a patient).

Effects of Single Mutations on Protein Stability Are Gaussian Distributed.

Biophys J 2020 06 1;118(12):2872-2878. Epub 2020 May 1.

Department of Chemistry & Chemical Biology, Harvard University, Cambridge, Massachusetts. Electronic address:

The distribution of protein stability effects is known to be well approximated by a Gaussian distribution from previous empirical fits. Starting from first-principles statistical mechanics, we more rigorously motivate this empirical observation by deriving per-residue-position protein stability effects to be Gaussian. Our derivation requires the number of amino acids to be large, which is satisfied by the standard set of 20 amino acids found in nature. Read More

Meat eating in wild hamadryas baboons: Opportunistic trade-offs between insects and vertebrates.

Am J Primatol 2019 07 11;81(7):e23029. Epub 2019 Jul 11.

Department of Anthropology, The Graduate Center, City University of New York, New York, New York.

The consumption of meat may provide herbivorous animals with important nutrients that are scarce in their plant-based diet. Seasonal variation in plant food availability has been suggested to motivate dietary flexibility in a range of species and thus primates may seek more prey when key plant resources are unavailable. Alternatively, prey encounter rate may drive meat eating. Read More

Cross-Generational Transmission of Early Life Stress Effects on HPA Regulators and Bdnf Are Mediated by Sex, Lineage, and Upbringing.

Front Behav Neurosci 2019 9;13:101. Epub 2019 May 9.

Developmental Neuropsychobiology Laboratory, Department of Psychology, Northeastern University, Boston, MA, United States.

Early life stress (ELS) is a potent developmental disruptor and increases the risk for psychopathology. Various forms of ELS have been studied in both humans and rodents, and have been implicated in altered DNA methylation, gene transcription, stress hormone levels, and behavior. Although recent studies have focused on stress-induced epigenetic changes, the extent to which ELS alters HPA axis function and stress responsivity across generations, whether these effects are sex-specific, and how lineage interacts with upbringing to impact these effects, remain unclear.

Experimental observation of the polarization coherence theorem.

Opt Lett 2019 Jan;44(1):159-162

For light fields, the manifestation of correlations between fluctuating electric field components at different space-time points is referred to as coherence, whereas these correlations appearing between orthogonal electric field components at a single space-time point are referred to as polarization. In this context, a natural question is as follows: how are coherence and polarization interconnected? Very recently, a tight equality P=V+D, namely, the "polarization coherence theorem" (PCT) connecting polarization P with interference visibility V (measure of coherence) and distinguishability D (measure of which-path information) has been proposed [Optica4, 1113 (2017)OPTIC82334-253610.1364/OPTICA.
