Differences of resting fMRI and cognitive function between drug-naïve bipolar disorder and schizophrenia

BMC Psychiatry, 2022
Background: Bipolar disorder (BD) and schizophrenia (SC) have many similarities in clinical manifestations. The acute phase of BD has psychotic symptoms, while SC also has emotional symptoms during the onset, which suggests that there is some uncertainty

Color-coordinate system from a 13th-century account of rainbows. [PDF]

, 2014
We present a new analysis of Robert Grosseteste’s account of color in his treatise De iride (On the Rainbow), dating from the early 13th century. The work explores color within the 3D framework set out in Grosseteste’s De colore [see J. Opt. Soc. Am.

Plane elasticity solution for a half-space weakened by a circular hole and loaded by a concentrated force

Journal of the Mechanical Behavior of Materials, 2013
We present a complete analytical solution for the plane elasticity problem of a concentrated force acting on a half-space weakened by a circular hole. The solution is based on the algorithm proposed by G.B.

Sine-Gordon/Coulomb Gas Soliton Correlation Functions and an Exact Evaluation of the Kosterlitz-Thouless Critical Exponent [PDF]

, 2004
We present an exact derivation for the asymptotic large distance behavior of the spin two-point correlation function in the XY-model. This allows for the exact obtainment of the critical exponent $\eta=1/4$ at the Kosterlitz-Thouless transition that ...

Functional magnetic resonance imaging studies in bipolar disorder in resting state: A coordinates-based meta-analysis

Psychiatry Research: Neuroimaging
Exploring changes in the intrinsic activity of the brain in people with bipolar disorder (BD) is necessary. However, the findings have not yet led to consistent conclusions. In this regard, this paper aims to extract more obvious differential brain areas and neuroimaging markers, for the purpose of providing assistance for early clinical diagnosis and ...

A Pair of Perfectly Conducting Disks in an External Field

Mathematical Modelling and Analysis, 2015
A pair of non-overlapping perfectly conducting equal disks embedded in a two-dimensional background was investigated by the classic method of images, by Poincar´e series, by use of the bipolar coordinates and by the elliptic functions in the previous ...

A collimated jet and an infalling-rotating disk in G192.16-3.84 traced by H2O maser emission [PDF]

, 2006
We report H2O masers associated with the massive-star forming region G192.16-3.84 observed with the new Japan VLBI network at three epochs spanned for two months, which have revealed the three-dimensional kinematical structure of the whole \h2o maser ...

Turkey’s Foreign Policy in the Post-Bipolar System of Coordinate

Journal of International Analytics, 2021
Turkey's foreign policy in the first decade after the collapse of the bipolar system retained features of its continuity in comparison with the Cold War: the Kemalist principles of laicism and the choice in favor of further Westernization, with its orientation towards cooperation with the EU and Euro-Atlantic structures remained firmly in place. However,
