, 2012 . The deep polar ice cores provide reference records commonly employed in global correlation of past climate events. However, temporal divergences reaching up to several thousand years (ka) exist between ice cores over the last climatic cycle.

Annals of Gastroenterological Surgery, EarlyView.In rectal cancer surgery, this study examined the risk factors for urinary dysfunction and the effect of autonomic nervous system resection extent on urinary dysfunction. Autonomic nervous system resection and lateral lymph node dissection were independent risk factors for urinary dysfunction.

Annals of Gastroenterological Surgery, EarlyView.The hepatospleno volume ratio and prealbumin levels 3 mo after major hepatectomy for perihilar cholangiocarcinoma are significant predictors of postoperative chronic liver failure (PCLF). The importance of this finding is that it emphasizes the need for targeted postoperative nutritional support and regular screening endoscopy to mitigate the risk of ...

Quantized Fields and Chronology Protection [PDF]
arXiv, 2000 Several recent possible counterexamples to the Chronology Protection Conjecture are critically examined. The ``adapted'' Rindler vacuum state constructed by Li and Gott for a conformal scalar field in Misner space is extended to nonconformally coupled and self-interacting scalar fields.

Trivial Lagrangians in the Causal Approach [PDF]
arXiv, 2015 We prove the non-uniqueness theorem for the chronological products of a gauge model. We use a cohomological language where the cochains are chronological products, gauge invariance means a cocycle restriction and coboundaries are expressions producing zero sandwiched between physical states.

Chronology protection in stationary 3D spacetimes [PDF]
, 2011 We address chronology protection in stationary, rotationally symmetric spacetimes in 2+1 dimensional gravity, focusing on the case of negative cosmological constant. We show that, if such spacetimes contain closed timelike curves, they belong to one of the following two classes: (i) bad asymptotics: the boundary itself contains closed timelike curves ...

Chronology of Elasticians [PDF]
Nature, 1886 IN forming a chronological list of writers on elasticity I have been unable to ascertain the following dates, which I should be much obliged if any of your readers would kindly supply: Mariotte (ne pres de Dijon vers 1620, Marie). Is nothing more definite known as to the date of his birth?
