BACKGROUND The functional localization of negativity bias, an influential index of emotion information processing, has yet to be identified. METHOD Depressed (n=47) and healthy participants (n=58) completed a clinical interview for DSM-IV Axis I disorders, symptom checklists, a behavioral task to measure negativity bias, and then viewed positive and negative images of social and nonsocial sce...

It has been widely believed that the non-negativity and the piecewise-constant constraints guarantee a unique solution to an interior tomographic problem. This letter points out that if the number of views is finite, the non-negativity and the piecewise-constant constraints do not guarantee a unique solution to an interior tomographic problem and the reconstruction could be biased by a constant...

This study investigates speakers’ assessment of the evaluative polarity of the members of eight antonym pairs, e.g., fast–slow and warm–cold, that are not inherently evaluative, unlike antonyms such as good–bad, ugly–beautiful. The contentful structures foregrounded by fast–slow and warm–cold are SPEED and TEMPERATURE, repectively, but the properties that they evoke may also be profiled against...

We investigated whether people monitor the outcomes of their own and their partners' individual actions as well as the outcome of their combined actions when performing joint actions together. Pairs of pianists memorized both parts of a piano duet. Each pianist then performed one part while their partner performed the other; EEG was recorded from both. Auditory outcomes (pitches) associated wit...

The Real Nonnegative Inverse Eigenvalue Problem (RNIEP) is that of characterizing all possible real spectra of nonnegative matrices. In this work we list some inclusion relations between several sufficient conditions and we study the negativity and the realizability margin of a spectrum with respect to these conditions.

There is an extensive literature on the negativity bias, including its conceptualization, measurement, temporal stability (individual differences), and neural and genetic associations. Hibbing et al. posit that the difference across individuals in the negativity bias is a key factor in determining political predisposition. The measures and paradigms developed in this literature provide a means ...

Man-made composite materials called "metamaterials" allow for the creation of unusual wave propagation behavior. Acoustic and elastic metamaterials in particular, can pave the way for the full control of sound in realizing cloaks of invisibility, perfect lenses and much more. In this work we design acousto-elastic surface modes that are similar to surface plasmons in metals and on highly conduc...

We study three different measures of quantum correlations---entanglement spectrum, entanglement entropy, and logarithmic negativity---for a ($1+1$)-dimensional massive scalar field in flat space-time. The spectrum for the discretized ground state indicates crossover zero-mode regime, which is further substantiated by an analytical treatment both entropy negativity. exact nature this depends on ...

  Effects of visual deprivation on the induction of epileptiform activity were studied in layer II/III of mature rat primary visual cortex. Field potentials were evoked by stimulation of layer IV in slices from control and dark-reared (OR) rats. Picrotoxin (PTX)-induced epileptic activity was characterized by spontaneous and evoked epileptic field potentials (EFPs). The results showed that OR s...

Background: The diagnosis of B-cell acute lymphoblastic leukemia (B-ALL) on the basis of the World Health Organization (WHO) recommendations in 2016 requires the expression of CD19 with CD79a (CD79a), cCD22 and CD10. CD79a is an integral B cell antigen expressed at all stages. Its absence in B-ALL has only been rarely reported. In this study, we described three cases of B-ALL showing complete l...
