Multichannel intraluminal impedance (MII) is a new technique for evaluation of bolus transport. We evaluated esophageal function using bolus transport time (BTT) and contraction wave velocity (CWV) of liquid, semisolid, and solid boluses. Ten healthy subjects underwent MII swallow evaluation with various boluses of sterile water (pH 5), applesauce, three different sized marshmallows, and iced a...

Brainstem transmission time (BTT) was studied in 71 subjects ranging in age from one day to 29 years in order to find a mathematical expression to best describe the relationship between BTT and age. The mathematical function which relates BTT to age is exponential. Using this data, the BTT confidence limit was calculated for subjects from birth through to eight years. Repeated recordings of aud...

Most derivatives do not have simple valuation formulas and must be priced by numerical methods such as tree models. Although the option prices computed by a tree model converges to the theoretical value as the number of time steps increases, the distribution error and the nonlinearity error may make the prices converge slowly or even oscillate significantly. This paper introduces a novel tree m...

We prove that there are computable enumerable incomplete btt-degres with the anticupping property. In fact no simple set is btt cuppable in the (not necessarily computable enumerable) btt-degrees. This solves a question of Odifreddi and settles the situation for the one remaining reducibility where the answer was unknown.

novel electron-rich fused aromatic unit, namely benzo[1,2-b:3,4b’:5,6-d’’]trithiophene (BTT), which holds promise as a building block for semiconductor materials. In comparison with the wellknown benzo[1,2-b:4,5-b’]dithiophene (BDT), quantumchemical calculations (B3LYP/6-31G*) predict the BTT unit to 40 be of similar donor strength. Thus, with R being alkyl chains, BTT is predicted to act as a ...

Most derivatives do not have simple valuation formulas and must be priced by numerical methods. However, the distribution error and the nonlinearity error introduced by many numerical methods make the pricing results converge slowly or even oscillate significantly. This paper introduces a novel tree model, the bino-trinomial tree (BTT) model, for pricing a wide range of derivatives. The BTT red...

BACKGROUND Squamous cell carcinomas (SCC) of the oral tongue (OT) and of the base of the tongue and tonsils (BTT) differ with respect to etiology, treatment and prognosis. Human papillomavirus has been linked to the increased incidence of BTT, yet, the trends in incidence of BTT and OT tumors among gender and ethnic origin groups have not been well examined. We sought to examine the trend in ge...

Acute myocardial infarction (AMI) is a rare, potentially fatal and often unrecognized complication of blunt thoracic trauma (BTT). Heart injury is diagnosed in less than 10% of all cases of blunt thoracic trauma. Medical literature is scarce in publications about AMI caused by BTT (AMI-BTT). There is no specific protocol on this issue. We describe two cases of AMI-BTT in young patients who were...

BACKGROUND The diagnostic criterion for beta thalassemia trait (BTT) is elevated Hb-A(2) levels. Iron deficiency anemia (IDA) reduces the synthesis of Hb-A(2), resulting in reduced Hb-A(2) levels, so patients with co-pathological conditions BTT with IDA, may have a normal level of Hb-A(2). Many socio-economic factors like unawareness, poor diagnostic facilities, and cost of molecular diagnosis ...

remaining 161 cases with an HbA2 level ≤3.5% constituted the non-BTT group. In the BTT group 3 cases had concomitant iron deficiency. In the non-BTT group 120 cases had a serum ferritin level <15 ng/mL and were diagnosed as IDA; of the remaining 41cases, 12 had associated chronic illness indicative of ACD (anemia of chronic disease) and in the other 29 the cause of microcytosis could not be ide...
