Objective: To establish that the laparoscopic approach to colorectal resection is safe with regards to postoperative morbidity and mortality in patients eighty years of age and over. Methods: Prospectively collected data for consecutive patients aged eighty years and older who underwent laparoscopic colorectal resection by the same surgeon (Dr. Daniel R. Kozman) from 1st January 2009 till 31st ...

We used functional magnetic resonance imaging (fMRI) to longitudinally examine brain plasticity arising from long-term, intensive simultaneous interpretation training. Simultaneous interpretation is a bilingual task with heavy executive control demands. We compared brain responses observed during simultaneous interpretation with those observed during simultaneous speech repetition (shadowing) i...

a r t i c l e i n f o This paper presents both analytics and numerical simulation results relevant to proposals for carbon motivated regional trade agreements summarized in Dong and Whalley (2010). Unlike traditional regional trade agreements, by lowing tariffs on participant's low carbon emission goods and setting penalties on outsiders to force them to join such agreements, carbon motivated r...

The Copenhagen interpretation According to modern physics, the world is made up from small bits of energy, called ‘quanta’. Each object in the world is a quantum system, made up of individual quanta acting together. In effect, this is like saying that the world and its objects are made up of interacting particles, except that quanta are not quite particles. The trouble is that quanta sometimes ...

We postulate bulk universal quantum computing (QC) cannot be achieved without surmounting the quantum uncertainty principle, an inherent barrier by empirical definition in the regime described by the Copenhagen interpretation of quantum theory the last remaining hurdle to bulk QC. To surmount uncertainty with probability 1, we redefine the basis for the qubit utilizing a unique form of M-Theore...

Probabilistic models (developped by workers such as Boltzmann, on foundations due to pioneers such as Bayes) were commonly regarded merely as approximations to a deterministic reality before the roles were reversed by the quantum revolution (under the leadership of Heisenberg and Dirac) whereby it was the deterministic description that was reduced to the status of an approximation, while the ro...

Anthropogenic emissions of greenhouse gases activate a number of feedback processes in the climate system. Scientists warn that some feedbacks can lead to abrupt and irreversible changes in climate dynamics, called tipping points. The threat of tipping points plays a major role in demands for aggressive emission reductions and for limiting warming to 2◦C, as agreed upon in the Copenhagen Accord...
