Carotid-cavernous fistulas (CCFs) pose an anatomically and physiologically challenging problem for clinicians. The most common method of treatment for these lesions is transvenous endovascular embolization via the inferior petrosal sinus or the facial vein. When transvenous access is not possible, an alternate approach must be devised. We describe a case example with bilateral Barrow Type B CCF...

Recently, changes in society have brought about the rediscovery of continuous cover forestry (CCF) as a forest management approach that helps to create multifunctional forests. However, practice CCF is only used relatively small area world, and its development potential unclear. We studied owners practising act niche experimenters provide clear-cutting-oriented Estonian with experience for spec...

This paper systematically investigates comoving Mpc scale intergalactic medium (IGM) environment around galaxies traced by the Ly$\alpha$ forest. Using our cosmological hydrodynamic simulations, we investigate IGM-galaxy connection at $z=2$ two methods: (I) cross-correlation analysis between and fluctuation of forest transmission ($\delta_\text{F}$); (II) comparing overdensity neutral hydrogen ...

In this short note, we demonstrate a simple and practical ORAM that enjoys an extremely simple proof of security. Our construction is based on a recent ORAM due to Shi, Chan, Stefanov and Li [SCSL11], but with some crucial modifications, which significantly simply the analysis. ∗Cornell University. {chung,rafael}@cs.cornell.edu Chung is supported in part by NSF Award CCF-1214844 and Pass’ Sloan...

INTRODUCTION This case report presents the pressure-lowering effect of transluminal fistula occlusion in a patient suffering from secondary glaucoma due to carotid cavernous fistula (CCF). CASE REPORT A 76-year-old Caucasian woman presented with dilated epibulbar vessels with elevated intraocular pressure (IOP, >30 mmHg) as well as glaucomatous excavations of the optic disc in both eyes. Cere...

Here we report a 79-year-old woman who presented with a 7-day history of headache, nausea, vomiting, and was found to have proptosis and ptosis. Laboratory findings showed hyponatremia, hypocortisolism, secondary hypothyroidism and low follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels. CT angiography (CTA) showed a vascular lesion in sella causing a mass affect on the pitui...

We show that given a satisfiable instance of the 2-to-1 Label Cover problem, it is NP-hard to find a ( 23 24 + )-satisfying assignment. ∗Department of Computer Science, University of Toronto.

We report a case of a ruptured aneurysm of the anomalous cerebellar artery originating from internal carotid artery presenting with a carotid cavernous fistula (CCF). An initial angiogram showed the typical appearance of a CCF with a direct fistulous tract with focal aneurysmal dilation from the ascending cavernous segment of the right internal carotid artery. A postembolization angiogram of th...

This paper presents an improved algorithm for computing the Combinatorial Canonical Form (CCF) of a layered mixed matrix A = Q T , which consists of a numerical matrix Q and a generic matrix T . The CCF is the (combinatorially unique) nest block-triangular form obtained by the row operations on the Q-part, followed by permutations of rows and columns of the whole matrix. The main ingredient of ...

This paper presents an efficient analytical approach using Composite Cost Function (CCF) for solving the Economic Dispatch problem with Multiple Fuel Options (EDMFO). The solution methodology comprises two stages. Firstly, the CCF of the plant is developed and the most economical fuel of each set can be easily identified for any load demand. In the next stage, for the selected fuels, CCF is eva...
