The discovery of Jupiter–like planets with high eccentricities raises the question of how these eccentricities are produced. We propose that eccentric giant planets (EGPs) could be formed in open star clusters as a result of purely dynami-cal processes. It is found that at least 3% of the giant planets around stars in open clusters can develop high eccentricities due to multi-body gravitational...

We present a method to control the size of giant unilamellar vesicles (GUVs), in which biochemical reaction can be encapsulated and conducted, with the aid of microfluidics. GUVs were formed by passing the water-in-oil (W/O) emulsion droplets through the second oil/water interface by centrifugation. Last year we showed that, by controlling the size of the initial W/O emulsion with a flow-focusi...

Background: The term gossypiboma denotes a mass of cotton that is accidentally retained in the body postoperatively. Case Report: Our case describes a 40-year-old female patient with a giant abdominal mass that occurred 9 years after a cesarean section delivery. Computed tomography scan and magnetic resonance imaging showed a 20-cm mass. A laparoscopic retrieval was performed with the placement...

We give an update on our OZ Survey to find more extremely metal poor (EMP) stars with [Fe/H] < —3 dex through mining the database of the Hamburg/ESO Survey. We present the most extreme such stars we have found from -̂ 1550 moderate resolution follow up spectra. One of these, HE1424—0241, has highly anomalous abundance ratios not seen in any previously known halo giant, with very deficient Si, mo...

We define pure intuitionistic differential nets, extending Ehrhard and Regnier’s differential interaction netswith the exponential box of Linear Logic.Normalization of the exponential reduction and confluence of the full one is proved. Though interesting and independent on their own, these results are directed and adjusted to give a translation of Boudol’s untyped λ-calculus with multiplicities...

We present a multiwavelength analysis of a compact group of galaxies infalling at high speed into the dynamically young cluster Abell 1367. Peculiar morphologies and unusually high Hα emission are associated with two giant galaxies and at least ten dwarfs/extragalactic HII regions, making this group the region with the highest density of star formation activity ever observed in the local cluste...

As part of our MITACS research project at Simon Fraser University, we have investigated algorithms for integer factorization and computing discrete logarithms. We have implemented a quadratic sieve algorithm for integer factorization in Maple to replace Maple’s implementation of the MorrisonBrillhart continued fraction algorithm which was done by Gaston Gonnet in the early 1980’s. We have also ...

Cystic abdominal tumors are extremely common and now a day they are diagnosed more frequently due to availability of better imaging modalities. Presentations of huge cysts have become rare as most of them are diagnosed and treated early. Still we get reports of patients with huge benign abdominal cysts and many of them are serous cyst adenoma of ovary. Sometimes, it becomes very difficult to id...

We present the results of a study of the morphology of the dwarf galaxy population in Abell 868, a rich, intermediate redshift (z=0.154) cluster which has a galaxy luminosity function with a steep faint-end slope (α=–1.26±0.05). A statistical background subtraction method is employed to study the B −R colour distribution of the cluster galaxies. This distribution suggests that the galaxies cont...

Extremely large optical Kerr non-linearities (n2) and (n4) were measured in two closed degenerate two-level transitions in the caesium D2 line when a probe and a coupling laser simultaneously probed and coupled the hyperfine structure in an atomic beam. The magnitude of the measured non-linearities in both transitions were found to be a function of the coupling laser intensity and of the probe ...
