BACKGROUND There is good evidence that psychotic symptoms segregate into symptom dimensions. However, it is still unclear how these dimensions are associated with risk indicators and other clinical variables, and whether they have advantages over categorical diagnosis in clinical practice. We investigated symptom dimensions in a first-onset psychosis sample and examined their associations with ...

One-way wave equations (OWWEs), derived from rational approximations, C(s) to I/x/1 S 2, are considered. Absorbing boundary conditions obtained from these OWWEs are easily implemented, producing systems of differential equations at the boundary which are different from those produced by rational approximations, r(s) to x/1 s 2. Although these systems are different, a particular choice of differ...

We present robust constraints from the Sloan Digital Sky Survey (SDSS) on the shape and distribution of the dark matter halo within the Milky Way (MW). Using the number density distribution and kinematics of SDSS halo stars, we probe the dark matter distribution to heliocentric distances exceeding ∼10 kpc and galactocentric distances exceeding ∼20 kpc. Our analysis utilizes Jeans equations to g...

The initiation and termination of tachyeardias were studied in five patients with Wolff-Parkinson-White syndrome, type A. In all patients, electrical stimulation was performed from the right side of the heart. In three patients the effect of induced left-sided premature beats was studied as well. In contrast to patients with WolffParkinson-White syndrome, type B, there was difficulty in initiat...

Let G be a connected linear algebraic group, let V be a finite dimensional algebraic G-module, and let a and b be two elements of V . We describe a constructive way to find out whether the G-orbit of a lies in the closure of the G-orbit of b.

For a graph G = (V,E), a set S ⊆ V is a [1, 2]-set if it is a dominating set for G and each vertex v ∈ V \S is dominated by at most two vertices of S, i.e. 1 ≤ |N(v)∩S| ≤ 2. Moreover a set S ⊆ V is a total [1, 2]-set if for each vertex of V , it is the case that 1 ≤ |N(v)∩S| ≤ 2. The [1, 2]-domination number of G, denoted γ[1,2](G), is the minimum number of vertices in a [1, 2]-set. Every [1, 2...

Let N , k, t, and v be positive integers. Let C be an N × k array with entries from an alphabet Σ of size v; we typically take Σ = {0, . . . , v − 1}. When (ν1, . . . , νt) is a t-tuple with νi ∈ Σ for 1 ≤ i ≤ t, (c1, . . . , ct) is a tuple of t column indices (ci ∈ {1, . . . , k}), and ci 6= cj whenever νi 6= νj , the t-tuple {(ci, νi) : 1 ≤ i ≤ t} is a t-way interaction. The array covers the ...
