Parameterization (closure) schemes in numerical weather and climate prediction models account for the effects of physical processes that cannot be resolved explicitly by these models. Methods for finding physical parameterization schemes that preserve conservation laws of systems of differential equations are introduced. These methods rest on the possibility to regard the problem of finding con...

We put forward a new class of mechanisms. In this extended abstract, we exemplify our approach only for single-good auctions in what we call a conservative-Bayesian setting. (Essentially, no commonknowledge about the underlying distribution of the players’ valuations is required.) We prove that our mechanism is optimal in this challenging and realistic setting.

Conservative treatment of exomphalos or omphalocele recommended by us in our textbook and performed by us in suitable cases for many years is not a panacea but has a limited application (Grob, 1957). This is due to the fact that in a high percentage (according to our own experience in more than 40% of cases) primary complications are present, requiring an early operation, or the condition is so...

A conservative formulation of the Lorentz force is given here for magnetohydrodynamic (MHD) flows at a low magnetic Reynolds number with the current density calculated based on Ohm’s law and the electrical potential formula. This conservative formula shows that the total momentum contributed from the Lorentz force is conservative when the applied magnetic field is constant. For the case with a ...

OBJECTIVE Evaluate the cause of infertility and impairment of tubal reproductive functions in infertility patients, who suffered tubal pregnancy after conservative treatment, using laparoscopy, hysteroscopic tubal catheterization, and hydrotubation. METHODS Seventy-five infertility patients treated for tubal pregnancies were divided into two groups based on past treatment methods of their tub...
