In the mid eighties, the System Architecture Research Centre at City University developed a message-passing, UNIX compliant micro kernel (Meshix) for our own scalable distributed memory architecture (Topsy). Over the last two years we have been engaged in a research programme aimed at learning from this experience, and developing a new operating system based on these lessons. The result is the ...

Introduction Based in Tel Aviv, Israel, Seraphim Sense Ltd is the creator of the Angel sensor, a wearable wristband with the capacity to track the user's vital signs. Founded by Eugene Jorov and Amir Schlomovich, the Angel device is the company’s first product and has been under development for the past two years. In 2013, Seraphim Sense launched a crowdfunding campaign on the web-based platfor...

We tested the effect of social isolation on the aggressiveness of an Amazonian fish: Astronotus ocellatus. Ten juvenile fishes were transferred from a group aquarium (60 x 60 x 40 cm) containing 15 individuals (without distinguishing sex) to an isolation aquarium (50 x 40 x 40 cm). Aggressiveness was tested by means of attacks on and displays toward the mirror image. The behavior was video-reco...

Based on a sample of 539 angel investors, we empirically test the impact of new ventures’ resource acquisition/allocation strategies in different development stages on angels’ abnormal returns and their extremeness. Our findings suggest that at earlier stages, ventures whose entrepreneurs focus more on securing new resources tend to not only give angel investors lower abnormal returns, but also...

rhaetian strata from the nayband formation of the tabas block, east- central iran, were studied palynologically. the materialexamined contained moderately diverse and well-preserved dinoflagellate cyst assemblages which lead to the identification ofrhaetogonyaulax rhaetica zone. the assigned age of this dinozone (rhaetian) is justified by plant fossils such as equisetitesarenaceus, scytophyllum...

This paper develops a theory of how angel and venture capital markets interact. Entrepreneurs first receive angel then venture capital funding. The two investor types are ‘friends’ in that they rely upon each other's investments. However, they are also ‘foes,’ because at the later stage the venture capitalists no longer need the angels. Using a costly search model we derive the equilibrium deal...

The kinematics of turning manoeuvres and the distance-time performance in escape responses of startled angelfish {Pterophyllum eimekei) are investigated employing high-speed cinematography (400Hz). All escape responses observed are C-type fast-starts, in which the fish assumes a C shape at the end of the initial body contraction (stage 1). Kinematic analysis of the subsequent stage (stage 2) al...
