It has become evident that mitral valve (MV) repair is the preferable treatment for the majority of patients presenting with severe mitral regurgitation (MR). This success clearly testifies that the surgical procedure is accessible, reproducible and is carrying excellent long-lasting results. From the pre-extracorporeal circulation's era to the last percutaneous approaches, a large variety of t...

A general problem confronting archaeologists is the seriation (or sequence-dating) problem. Sir W.M. Flinders Petrie, a famous archeologist, was the first to formulate this interesting and important problem in mathematical terms almost one hundred years ago. The problem of trying to chronologically order grave sites in a cemetery where each grave contains (or does not contain) a number of diffe...

Chronologically, the first was by the United Nations in its series on the ‘World’s Social Situation’. Although not mentioned, I must begin by acknowledging that I drafted the report, which was revised by the UN DESA Secretariat, with significant cuts and insertion of ILO statistics, on which I was not invited to comment. The Report’s origins lay in a desire to consider trends in patterns of wor...

We calculate the four-wave-mixing signal of excitons generated at k(4) = k(1) + k(2) - k(3) by two pulsed entangled photon pairs (k(1), k(2))and(k(3), k(4)), where all four modes are chronologically ordered. Entangled photons offer an unusual combination of bandwidths and temporal resolution not possible by classical beams. Contributions from different resonances can be selected by varying the ...

This study tackles the historical methodology of Al_Muhibi in his book (Kulaste AL'ather), It also aims at shedding light on very distinguished through Kulaste AL'ather, and is one most important translation books that period. The results indicated followed own style he was careful selection words to maintain meaning, chose rhetorical methods, out content comprehensiveness translations, confine...

Fuzzy time series approaches, which do not require the strict assumptions of traditional time series approaches, generally consist of three stages. These stages are called as the fuzzification of crisp time series observations, the identification of fuzzy relationships and the defuzzification, respectively. All of these stages play an important role on the forecasting performance of the model. ...

Historically, coronaviruses have been recognized as a cause of minor respiratory infections in humans. However, the recent identification of three novel human coronaviruses, one causing severe acute respiratory syndrome (SARS), has prompted further examination of these viruses. Previous studies of geographically and chronologically distinct Human coronavirus 229E (HCoV-229E) isolates have found...

Yeast chronological lifespan (CLS) is extended by multiple genetic and environmental manipulations, including caloric restriction (CR). Understanding the common changes in molecular pathways induced by such manipulations could potentially reveal conserved longevity mechanisms. We therefore performed gene expression profiling on several long-lived yeast populations, including anade4∆mutant defec...

Much corpus-linguistic research is concerned with the development of particular parameters over time. For example, in L1/L2 acquisition/learning, the syntactic development of a child/learner is approximated on the basis of how mean lengths of utterances (MLU), t-unit-based measures, or IPSyn values change over time (cf. Shirai and Andersen 1995 or Ortega 2003). Similarly, in historical linguist...
