Closed-loop brain stimulation augments fear extinction in male rats
Nature Communications, 2023 Dysregulated fear reactions can result from maladaptive processing of trauma-related memories. In post-traumatic stress disorder (PTSD) and other psychiatric disorders, dysfunctional extinction learning prevents discretization of trauma-related memory ...

Coding and noncoding transcriptomes of NODULIN HOMEOBOX (NDX)-deficient Arabidopsis inflorescence
Scientific Data, 2023 Arabidopsis NODULIN HOMEOBOX (NDX) is a plant-specific transcriptional regulator whose role in small RNA biogenesis and heterochromatin homeostasis has recently been described. Here we extend our previous transcriptomic analysis to the flowering stage of

Early Diagnosis of COVID-19 Images Using Optimal CNN Hyperparameters
Diagnostics, 2022 Coronavirus disease (COVID-19) is a worldwide epidemic that poses substantial health hazards. However, COVID-19 diagnostic test sensitivity is still restricted due to abnormalities in specimen processing.

Journal of Empirical Finance, 2009 Conventional momentum strategies exhibit substantial time-varying exposures to the Fama and French factors. We show that these exposures can be reduced by ranking stocks on residual stock returns instead of total returns. As a consequence, residual momentum earns risk-adjusted profits that are about twice as large as those associated with total return ...

Overlap singularity and time evolution in integrable quantum field theory
Journal of High Energy Physics, 2018 We study homogeneous quenches in integrable quantum field theory where the initial state contains zero-momentum particles. We demonstrate that the two-particle pair amplitude necessarily has a singularity at the two-particle threshold.

Relevant gluonic energy scale of spontaneous chiral symmetry breaking from lattice QCD [PDF]
, 2010 We analyze which momentum component of the gluon field induces spontaneous chiral symmetry breaking in lattice QCD. After removing the high-momentum or low-momentum component of the gluon field, we calculate the chiral condensate and observe the roles of

Angular Momentum and Energy-Momentum Densities as Gauge Currents [PDF]
, 2002 If we replace the general spacetime group of diffeomorphisms by transformations taking place in the tangent space, general relativity can be interpreted as a gauge theory, and in particular as a gauge theory for the Lorentz group.

SSRN Electronic Journal, 2017 A new type of momentum based on past return signs is introduced, called Returns Signal Momentum. This is mainly driven by sign dependence, which is positively related to average return and negatively related to return volatility. An empirical application using a universe of commodity and financial futures offers supporting evidence to this momentum ...
