Bacillus spp. and Clostridium spp. form a specialized cell type, called a spore, during a multistep differentiation process that is initiated in response to starvation. Spores are protected by a morphologically complex protein coat. The Bacillus anthracis coat is of particular interest because the spore is the infective particle of anthrax. We determined(More)
We build a general equilibrium model of occupation choice, where the risks inherent in a technology embodying a new innovation are only vaguely known (ambiguous), whereas the old technology has known risks. Using the Arrow-Hurwicz criterion to characterise decision-making in the face of ambiguity, we distinguish agents according to their degree of ambiguity(More)
One of the pitfalls of FPGA design is the relatively long implementation time when compared to alternative architectures, such as CPU, GPU or DSP. This time can be greatly reduced however by using tools that can generate hardware systems in the form of a hardware description language (HDL) from high-level languages such as C, C++, or Python. Such(More)
Entrepreneurs may undertake investments when returns cannot be precisely evaluated: they are decisive. Lenders may require high compensation to place funds in those ventures: they are cautious. We analyze optimal ¯nancing contracts between entrepreneurs and lenders. Decisiveness and cautiousness are characterized using Bewley's (1986) incomplete preferences(More)
HYPOTHESIS Exposure to ciprofloxacin/dexamethasone, but not ofloxacin, prolongs tympanic membrane (TM) healing. BACKGROUND Exposure to hydrocortisone has been shown to delay TM wound healing. No published studies have compared the effects of ciprofloxacin/dexamethasone and ofloxacin on TM healing. METHODS Noninfected TM perforations were created in 30(More)
A 62-year-old man presented to the emergency department one week after accidentally drinking an alkaline cleaning agent stored in unlabeled bottle. The day of the incident the patient presented to an outside hospital where he was admitted for an upper endoscopy of the esophagus which was found to be negative for acute injury. An initial chest X-ray taken(More)
