While a user’s preference is directly reflected in the interactive choice process between her and the recommender, this wealth of information was not fully exploited for learning recommender models. In particular, existing collaborative filtering (CF) approaches take into account only the binary events of user actions but totally disregard the contexts in which users’ decisions are made. In thi...

RATIONALE Orbital compartment syndrome (OCS) is a rare occurrence after transvenous embolization of indirect carotid-cavernous fistula (CCF). A lateral canthotomy and cantholysis are the most commonly performed surgical interventions. In our case, as the acute OCS occurred immediately after an uneventful transvenous embolization, an orbital floor orbitectomy was performed. PATIENT CONCERNS He...

We provide a constructive proof of Border’s theorem [Bor91, HR15a] and its generalization to reduced-form auctions with asymmetric bidders [Bor07, MV10, CKM13]. Given a reduced form, we identify a subset of Border constraints that are necessary and sufficient to determine its feasibility. Importantly, the number of these constraints is linear in the total number of bidder types. In addition, we...

BACKGROUND Anaemia increases morbidity and mortality in patients with congestive cardiac failure (CCF). Few studies have examined the prevalence of anaemia and its impact among patients with CCF in sub-Saharan Africa. We assessed the prevalence of anaemia and its influence on treatment outcome in patients with CCF attending a large referral hospital in Kampala, Uganda. METHODS Echocardiograph...

Inhibitors of carbohydrate-hydrolysing enzymes play an important role for the treatment of diabetes. One of the therapeutic methods for decreasing of postprandial hyperglycemia is to retard absorption of glucose by the inhibition of carbohydrate- hydrolysing enzymes, such as α-glucosidase, in the digestive organs. To investigate the therapeutic potential of compounds from natural sources, Calli...

Human walking involves coordinated movement between lower limbs. Locomotion is a neuromuscular activity and hence it is affected by mental tasks. Many studies on gait parameter e.g. stride length, gait speed, cadence and percentage of gait cycle in a double limb stance has been performed to determine the effect of a mental task on locomotive task. The knee being an important joint for locomotiv...

Fused filament fabrication (FFF) has been used to create prototypes and functional parts for various applications using plastic filaments. It also extended the use of continuous fibers reinforcing thermoplastic polymers. This study aims optimize deposition design a coextruded carbon fiber (CCF) composite with polyethylene terephthalate glycol?modified (PETG) filament. The characterizations on r...

We report the case of a recurrent carotid cavernous fistula (CCF) originating from a giant cerebral aneurysm (GCA) after placement of a covered stent. A 47-year-old woman presented with sudden onset of severe headache, and left-sided exophthalmos and ptosis. Cerebral angiography revealed a CCF caused by rupture of a GCA in the cavernous segment of the left internal carotid artery. Two covered s...

BACKGROUND Carotid cavernous fistula (CCF) is an abnormal communication between the carotid artery and the cavernous sinus. The pathogenesis of spontaneous CCF remains unclear, although sinus thrombosis is known to be a predisposing factor for dural arteriovenous fistula. Because spontaneous CCFs are mainly of the dural type, we considered that thrombogenic conditions, such as, protein S defici...
