We examine in a unified framework three recent perspectives on country risk: debt intolerance, original sin, and currency mismatches. We find statistical evidence supporting aspects of all three, though the strength of that support varies considerably across hypotheses and a number of open questions remain. Our evidence is consistent with the view that good domestic macroeconomic and structural...

To determine if individuals with extensive exposure to rodent habitats were infected with Sin Nombre hantavirus (SNV), we evaluated forest and park service personnel from the region of endemicity in the southwestern United States. Information about work and recreational activities, including exposure to rodents and a history of recent illnesses, was obtained via a standardized questionnaire. Se...

Problem P01: Compute the first N decimal digits after the decimal point of sin(sin(sin 1)), rounded toward zero. We have sin(sin(sin 1)) ≈ 0.678: the first N decimal digits after the decimal point match the first N mantissa digits. We use a target decimal precision N1 > N , and a binary precision p. We compute x = ◦(sin 1), y = ◦(sinx), z = ◦(sin y), with all roundings to nearest. It is easy to...

To determine how the memory B cell population elicited to one epitope might be used in immune responses to other, structurally related epitopes, we explored the phenomenon of original antigenic sin. Strain A/J mice reproducibly respond to immunization with p-azophenylarsonate (Ars) by production of anti-Ars antibodies encoded predominantly by a single VH gene segment (VHIdCR). The structural an...

in a structural analysis, the “rebellion & decline” theme creates a narrative structure in which eleven stories of shāhnāmeh – equal to 3.18 per cent of the whole epic – are included, which makes it the tenth largest sequence of the shāhnāmeh. this narrative structure (sequence) consists of initial tranquillity, the king’s rebellion, his decline, and ultimate tranquillity. the epical theme of r...

When a new infectious disease emerges, memory cells from previous exposure to related, but different, micro-organism may become activated. This phenomenon has been termed the original antigenic sin. induced antibodies against related would be not functional, sin impair effectivity of primary response. Otherwise, turn out virtue because response contribute elimination emerging disease.

In a new simple application of the non-Abelian discrete symmetry A4 to chargedlepton and neutrino mass matrices, we show that for the current experimental central value of sin 2θ13 ≃ 0.1, leptonic CP violation is necessarily large, i.e. | tan δCP | > 1.3. The non-Abelian discrete symmetry A4 was introduced [1, 2, 3] to achieve the seemingly impossible, i.e. the existence of a lepton family symm...
