We present the radio light curves of lensed images of the gravitational lens B1422+231. The observations have been carried out using the VLA at 8.4 and 15 GHz over a period of 197 days. We describe a method to estimate the time delay from the observed light curves. Using this method, our cross-correlation analysis shows that the time delay between images B and A is 1.5±1.4d, between A and C is ...

A criticism of mechanism design theory is that the optimal mechanism designed for one environment can produce drastically different actions, outcomes, and payoffs in a second, even slightly different, environment. In this sense, the theoretically optimal mechanisms usually studied are not "robust." In order to study robust mechanisms while maintaining an optimal contracting approach, we study a...

Excessive consumption of acidic drinks and foods contributes to tooth erosion. The aims of the present in vitro study were twofold: (1) to assess the erosive potential of different dietary substances and medications; (2) to determine the chemical properties with an impact on the erosive potential. We selected sixty agents: soft drinks, an energy drink, sports drinks, alcoholic drinks, juice, fr...

BACKGROUND Studies have shown a correlation between bipolar disorder and diabetes mellitus. It is unclear if this correlation is a part of common pathophysiological pathways, or if medication for bipolar disorder has negative effects on blood sugar regulation. METHODS The Norwegian prescription database was analyzed. Prescriptions for lithium, lamotrigine, carbamazepine and valproate were use...

A short-term test in vitro is described, which can be used to detect resistance to cytostatic agents in leukaemic cells. Leukaemic cell suspensions were incubated with cytostatic agents and the resulting intracellular ATP concentrations were measured by a bioluminescence ATP assay. There was a clear dose-effect relationship in acute leukaemia and chronic lymphocytic leukaemia cells for drugs us...

We consider a model of self-propelled agents with spring-like interactions that depend only on relative positions, and not on relative orientations. We observe that groups of these agents self-organize to achieve collective motion (CM) through a mechanism based on the cascading of self-propulsion energy towards lower elastic modes. By computing the correlation functions of the speed and velocit...

Interstitial ̄uid pressure (IFP) is one of the main obstacles for macromolecular agents uptake and distribution in solid tumors. It has been demonstrated to reduce e€ectiveness of different macromolecular agents used in in vivo anti-tumor therapies, which on the other hand showed very good anti-tumor properties in in vitro conditions [L.T. Baxter, R.K. Jain, Microvascular Research 37 (1989) 77±...

This paper presents a non-manual design engineering method based on heuristic search algorithm to search for candidate agents in the solution space which formed by artificial intelligence agents modeled on the base of bionics. Compared with the artificial design method represented by meta-learning and the bionics method represented by the neural architecture chip, this method is more feasible f...

This paper presents a distributed intrusion detection system IDS, based on the concept of specialized distributed agents community representing agents with the same purpose for detecting distributed attacks. The semantic of intrusion events occurring in a predetermined network has been defined. The correlation rules referring the process which our proposed IDS combines the captured events that ...
