Several fields still need primates

Fields with several Commuting Derivations

The existentially closed models of the theory of fields (of arbitrary characteristic) with a given finite number of commuting derivations can be characterized geometrically, in several ways. In each case, the existentially closed models are those models that contain points of certain differential varieties, which are determined by certain ordinary varieties. How can we tell whether a given syst...

We still need to operate at night!

INTRODUCTION In the past the National Confidential Enquiry into Peri-operative deaths (NCEPOD) have advocated a reduction in non-essential night-time operating in NHS hospitals. In this study a retrospective analysis of the emergency general surgical operative workload at a London Teaching centre was performed. METHODS All general surgical and vascular emergency operations recorded prospectiv...

A few scope details still need attention.

Yes , we still need Universal Grammar

In a recent paper [Lidz, J., Gleitman, H., & Gleitman, L. (2003). Understanding how input matters: Verb learning and the footprint of universal grammar. Cognition, 87, 151–178], we provided crosslinguistic evidence in favor of the following linked assertions: (i) Verb argument structure is a correlate of verb meaning; (ii) However, argument structure is not directly available to learners as a c...

Do we still need organic nitrates?

rganic nitrates are still quite frequently used for the reatment of acute and chronic angina, and acute and hronic congestive heart failure. When given acutely, their ffectiveness is undisputable; however, their long-term effiacy is substantially limited due to the development of olerance (1) and the induction of endothelial dysfunction (2), parameter that has prognostic significance in patient...
