We study the usage of negation in JSON Schema data modeling. Negation is a logical operator rarely present type systems and schema description languages, since it complicates decision problems: many software tools, but also formal frameworks for working with Schema, do not fully support negation. This motivates us to whether actually used practice, which aims, could—in principle—be replaced by ...

Hierarchical social networks appear in a variety of contexts, such as the on-line social network Twitter, the social organization of companies, and terrorist networks. We examine a dynamic model for the disruption of information flow in hierarchical social networks by considering the vertex-pursuit game Seepage played in directed acyclic graphs (DAGs). In Seepage, agents attempt to block the mo...

We show that Kempen and Harbusch’s (Cognition (2003) this issue) arguments against our claims cannot be upheld. On the one hand, their alternative account of our data that is based on the availability of constructions with object-experiencer verbs is not compatible with the literature on the processing of these types of sentences in German. Moreover, their allegation that we failed to conduct a...

The patient opened the package of suppositories and looked at the pharmacist with a puzzled expression. He took one of the suppositories in his hand as he spoke to the pharmacist in Spanish. The pharmacist answered in English, “I don’t understand Spanish” and pointed to his mouth, “Can you speak any English?” The patient saw the pharmacist’s gesture, smiled, nodded, and placed the capsule in hi...

We present MatrixView (MV) – a setup to increase immersion in video conferencing systems. MV consists of a pan-tilt video camera mounted on a car which moves along a horizontal track. The car moves in such a way, that the user is kept in the center of the image (“Matrix” movie effect, see Figure 1). Using this setup in a video conference application, enables a remote user to manipulate his virt...

1. Head-bobbing of pigeons during walking and landing was studied using high-speed motion photography. 2. The analysis of film records indicated that head-bobbing whilst walking consists of two phases: one where the head is 'locked' in space but moves backward relative to its forward moving body; and another where it is thrust rapidly forward to a new position. 3. The fact that head-bobbing is ...

This paper examines downward price rigidity in Iranian house market and discusses whether this characteristic would result in an asymmetric relationship between house price and monetary policy. To test the downward house price rigidity the threshold GARCH model is employed. The asymmetric adjustment to monetary policy is examined using the asymmetric cointegration and error correction models. T...

We present a retinal-surgery telemanipulation system with submicron precision that is compact enough to be head-mounted and that uses a full range of existing disposable instruments. Two actuation mechanisms are described that enable the use of actuated instruments, and an instrument adapter enables quick-change of instruments. Experiments on a phantom eye show that telemanipulated surgery resu...

Stimulation of tentacle-specific cell differentiation by the neuropeptide head activator was investigated in Hydra magnipapillata. Tentacle-specific sensory nerve cells were identified by a monoclonal antibody, NV1. Treatment of hydra with 1 pM head activator for 18 h stimulated differentiation of NV1 nerve cells and tentacle epithelial cells in tissue from the distal gastric region. Head tissu...
