Cingulate-Hippocampus Coherence and Trajectory Coding in a Sequential Choice Task
(Elsevier, 2013-11)Interactions between cortex and hippocampus are believed to play a role in the acquisition and maintenance of memories. Distinct types of coordinated oscillatory activity, namely at theta frequency, are hypothesized to ... -
Cingulate-motor circuits update rule representations for sequential choice decisions
(Springer Science and Business Media LLC, 2022)<jats:title>Abstract</jats:title><jats:p>Anterior cingulate cortex mediates the flexible updating of an animal’s choice responses upon rule changes in the environment. However, how anterior cingulate cortex entrains motor ... -
Cingulum-Callosal White-Matter Microstructure Associated with Emotional Dysregulation in Children: A Diffusion Tensor Imaging Study
(Elsevier BV, 2020)© 2020 The Author(s) Emotional dysregulation symptoms in youth frequently predispose individuals to increased risk for mood disorders and other mental health difficulties. These symptoms are also known as a behavioral risk ... -
Circadian Gating of the Cell Cycle Revealed in Single Cyanobacterial Cells
(American Association for the Advancement of Science, 2010-03)Although major progress has been made in uncovering the machinery that underlies individual biological clocks, much less is known about how multiple clocks coordinate their oscillations. We simultaneously tracked cell ... -
Circadian Rhythm Disruption Promotes Lung Tumorigenesis
(Elsevier, 2018-07)Circadian rhythms are 24-hr oscillations that control a variety of biological processes in living systems, including two hallmarks of cancer, cell division and metabolism. Circadian rhythm disruption by shift work is ... -
Circadian rhythm in critically ill patients: Insights from the eICU Database
(Elsevier BV, 2021-02) -
Circadian Rhythms in Rho1 Activity Regulate Neuronal Plasticity and Network Hierarchy
(Elsevier, 2015-07)Neuronal plasticity helps animals learn from their environment. However, it is challenging to link specific changes in defined neurons to altered behavior. Here, we focus on circadian rhythms in the structure of the principal ... -
Circle of Willis anomalies in Turner syndrome: Absent A1 segment of the anterior cerebral artery
(Wiley, 2019-10)Purpose: Turner syndrome (TS) is the most common sex chromosome disorder in women and is associated with a higher than expected death rate secondary to cerebrovascular disease, including stroke. This study evaluates the ... -
Circle Packing for Origami Design Is Hard
(AK Peters, Ltd. / CRC Press, 2011-06-21)Over the past 20 years, the world of origami has been changed by the introduction of design algorithms that bear a close relationship to, if not outright ancestry from, computational geometry. One of the first robust ... -
Circuit Lower Bounds for Nondeterministic Quasi-polytime from a New Easy Witness Lemma
(Society for Industrial & Applied Mathematics (SIAM), 2020)© 2020 Society for Industrial and Applied Mathematics. We prove that if every problem in N P has nk-size circuits for a fixed constant k, then for every N P -verifier and every yes-instance x of length n for that verifier, ... -
Circuit lower bounds for nondeterministic quasi-polytime: an easy witness lemma for NP and NQP
(Association for Computing Machinery (ACM), 2018-06)We prove that if every problem in NP has nk-size circuits for a fixed constant k, then for every NP-verifier and every yes-instance x of length n for that verifier, the verifier’s search space has an nO(k3)size witness ... -
A circuit mechanism for differentiating positive and negative associations
(Nature Publishing Group, 2015-04)The ability to differentiate stimuli predicting positive or negative outcomes is critical for survival, and perturbations of emotional processing underlie many psychiatric disease states. Synaptic plasticity in the basolateral ... -
Circuit models of stochastic genetic networks
(Institute of Electrical and Electronics Engineers, 2009-12)We use analogies between chemistry and subthreshold electronics to develop fast, scalable, digitally programmable hardware models of stochastic genetic networks. We also present experimental results from a prototype 0.18 ... -
Circuit synthesizable guaranteed passive modeling for multiport structures
(Institute of Electrical and Electronics Engineers (IEEE), 2010-09)In this paper we present a highly efficient algorithm to automatically generate circuit synthesizable dynamical models for passive multiport structures. The algorithm is based on a natural convex relaxation of the original ... -
Circuit-ABE from LWE: Unbounded Attributes and Semi-adaptive Security
(Springer, 2016-07)We construct an LWE-based key-policy attribute-based encryption (ABE) scheme that supports attributes of unbounded polynomial length. Namely, the size of the public parameters is a fixed polynomial in the security parameter ... -
Circuit-Selective Striatal Synaptic Dysfunction in the Sapap3 Knockout Mouse Model of Obsessive-Compulsive Disorder
(Elsevier, 2013-02)Background: Synapse-associated protein 90/postsynaptic density protein 95-associated protein 3 (SAPAP3) is an excitatory postsynaptic protein implicated in the pathogenesis of obsessive-compulsive behaviors. In mice, genetic ... -
CircuitAssist: Automatically Dispensing Electronic Components to Facilitate Circuit Building
(ACM|The Adjunct Publication of the 35th Annual ACM Symposium on User Interface Software and Technology, 2022-10-29) -
A Circuitous Route to Noncoding RNA
(American Association for the Advancement of Science (AAAS), 2013-04)Most genetic information is expressed as, and transacted by, proteins. Yet, less than 2% of the human genome actually codes for proteins, prompting a search for functions for the other 98% of the genome, once considered ... -
Circuits Resilient to Short-Circuit Errors
(ACM|Proceedings of the 54th Annual ACM SIGACT Symposium on Theory of Computing, 2022-06-09) -
Circuitscape in Julia: Empowering Dynamic Approaches to Connectivity Assessment
(Multidisciplinary Digital Publishing Institute, 2021-03-15)The conservation field is experiencing a rapid increase in the amount, variety, and quality of spatial data that can help us understand species movement and landscape connectivity patterns. As interest grows in more dynamic ...
