Beating the Standard Model *
نویسنده
چکیده
Although our beloved standard model of quarks and leptons offers a complete, consistent and correct description of most particle phenomena, lots of vexing questions remain unanswered, such as: Why are the gauge group and the fermion masses what they are? Why three families of quarks and leptons? What breaks electroweak symmetry? How about gravity? Leaving such profound meta-questions to supersymmetrists, string theorists and their successors, we shall beat on two unrelated and more modest puzzles: the origin of CP violation and the reported observation of cosmic-ray events with unexpectedly high energies.

Use of Carbon dioxide versus air blower in on-pump beating-heart coronary artery bypass surgery
Introduction: The use of carbon dioxide blower has been recognized as the standard of care in patients undergoing beating coronary artery bypass grafting (CABG) due to higher solubility and lower risk of embolization. On the other hand, the compressed air blower has gone out of use since air can be easily trapped and is less soluble which can cause coronary embolism. The prese...
متن کاملOn-Pump Beating Coronary Artery Bypass in High Risk Coronary Patients
Background: There are some conflicting results with Conventional Coronary Artery Bypass Grafts (CCABG) with arrested heart in coronary high-risk patients. Moreover, performing off-pump CABG in these cases may be associated with serious complications. The objective of this study is to evaluate the efficacy of the on-pump beating CABG (OPBCABG) in coronary high-risk patients in comparison with th...
متن کاملModification of ciliary beating in sea urchin larvae induced by neurotransmitters: beat-plane rotation and control of frequency fluctuation
The modification of ciliary beating by neurotransmitters in sea urchin larvae at the four-armed pluteus stage was analyzed in terms of the direction of beating and fluctuation in the beat period. Application of dopamine to Pseudocentrotus depressus causes the cilia to turn their beat plane but retain its characteristic planar feature up to the complete 'reversal' of the beat direction. This new...

Symmetric and asymmetric knots, as two original knots, possess different physical and mechanical properties that influence the function of a carpet. Jufti and U knots give different properties to the carpet compared to the original ones. If they were used to produce specific properties, they would enhance the carpet's quality. However, nowadays their applications are considered as methods that ...

Background: It is generally accepted that the selective adenosine triphosphate-dependent potassium channel openers (KATP openers) have a dramatic role in the treatment of some cardiovascular disorders. The aim of this study was to investigate the effects of diazoxide, a potent ATP-related potassium channel opener, on spontaneously beating isolated rat atria to achieve more accurate approaches t...
