A detailed discussion of the point in polygon problem for arbitrary polygons is given. Two concepts for solving this problem are known in literature: the even-odd rule and the winding number, the former leading to ray-crossing, the latter to angle summation algorithms. First we show by mathematical means that both concepts are very closely related, thereby developing a first version of an algor...

Let C be a binary linear self-dual doubly-even code of length n and minimal weight d. Such codes exist only if 12 = 0 (mod 8). We put II = 24r + 8s, s = 0, 1, 2. It follows from the work of Gleason [2] and of Mallows and Sloane [6] that d s 4r + 4. C is called extremal if d = 4r + 4. In the following, an extremal code means a binary linear self-dual doubly-even extremal code. We use the set-the...

Individuals nonconsciously and unintentionally pursue goals they associate with relationship partners (Fitzsimons & Bargh, 2003; Shah, 2003). Here, we demonstrate conditions under which individuals nonconsciously and unintentionally reject goals they associate with relationship partners and instead pursue opposing goals. In Experiment 1, participants were subliminally primed with the name of a ...

We show that the ring of the weight enumerators of a self-dual doubly even code dn in arbitrary genus is finitely generated. Indeed enough elements to generate it are given. The latter result is applied to obtain a minimal set of generators of the ring in genus two.

Using a new method, we examined whether incidental perception of need-rewarding (positive) objects unintentionally prepares motor action. Participants who varied in their level of need for water were presented with glasses of water (and control objects) that were accompanied by go and no-go cues that required a response (key-press) or withholding a response. Importantly, if need-rewarding objec...

Studies based on closed claims are very important in our efforts to improve patient safety. For patients, complications of anaesthesia can be compared with ‘friendly fire’. Harm is done unintentionally by somebody whose aim was to help. Patients may be seriously injured or even die due to a complication of anaesthesia, and such events may also lead to serious psychological consequences for the ...

When eyewitnesses are exposed to misinformation about an event from a co-witness, they often incorporate this misinformation in their recall of the event. The current research aimed to investigate whether this memory conformity phenomenon is due to change in the witness‟s memory for the event, or to social pressures to conform to the co-witness‟s account. Participants were shown a crime video a...
