1-Methyl-3-phenylimidazolidine-2-thione

Acta Crystallographica Section E, 2014
The asymmetric unit of the title cyclic thiourea derivative, C10H12N2S, comprises two molecules, each of which has a twist about the CH2—CH2 bond within the five-membered ring.

Testing for a unit root in the presence of a possible break in trend [PDF]

In this paper we consider the issue of testing a time series for a unit root in the possible presence of a break in a linear deterministic trend at some unknown point in the series.

(2,3-Di-2-pyridylpyrazine-κ2N2,N3)diiodidopalladium(II)

Acta Crystallographica Section E, 2011
The PdII ion in the title complex, [PdI2(C14H10N4)], is four-coordinated in a slightly distorted square-planar environment by the two pyridine N atoms of the chelating 2,3-di-2-pyridylpyrazine (dpp) ligand and two iodide anions.

Fading-Memory Quaternion-Based Kalman Filter for Quantum Channel PMD Compensation

IEEE Access
Polarization mode dispersion in optical fibers corrupts polarization-encoded quantum states through random, time- and frequency-varying rotations. Because quantum states cannot be directly measured and reused without disturbance, practical mitigation ...

Behaviour of Dickey-Fuller Unit Root Tests Under Trend Misspecification [PDF]

We analyse the case where a unit root test is based on a Dickey-Fuller regression whose only deterministic term is a fixed intercept. Suppose, however, as could well be the case, that the actual data generating process includes a broken linear trend.

Unique Set Cover on Unit Disks and Unit Squares

CoRR, 2016
We study the Unique Set Cover problem on unit disks and unit squares. For a given set $P$ of $n$ points and a set $D$ of $m$ geometric objects both in the plane, the objective of the Unique Set Cover problem is to select a subset $D'\subseteq D$ of objects such that every point in $P$ is covered by at least one object in $D'$ and the number of points ...
