Training Systems for Mechanization in Vineyards

Most 'Concord' vineyards in Arkansas have been trained to the Umbrella Kniffin (UK) system and pruned to a 30+10 schedule. In the Geneva Double Curtain (GDC) training system (a 1.2 m divided double curtain "T" type trellis) shoots are positioned vertically toward the vineyard floor. Under northern conditions, this system allows better distribution of fruiting spurs, reduced shading of interior ...

Aram Harrow - Quantum Monte Carlo vs Tunneling in Adiabatic Optimization

In this talk I'll present a quantum algorithm for solving semidefinite programs (SDPs). It has worst case running time O((nm)^1/2 r), with n and r the dimension and sparsity of the input matrices, respectively, and m the number of constraints. In contrast any classical method requires at least Omega(nm) time to solve the problem. I'll discuss how for some instances the algorithm might offer eve...

Epidemiology of gonococcal and chlamydial infections in Harrow and Brent.

OBJECTIVE To describe the epidemiology and associated clinical features of gonorrhoea and chlamydial infection and to develop a profile of sexually transmitted diseases (STDs) in an outer London health district. DESIGN Hospital-based retrospective study. SETTING Genitourinary medicine clinic, Northwick Park Hospital, Harrow and Brent Health Authority. SUBJECTS 70 male and female individua...

Rotary replication for freeze-etching

Rotary replication has been adapted to freeze-etching and evaluated using T4 polyheads, erythrocyte ghosts, and chloroplast membranes. Conventional electron microscopy, electron diffraction, and optical diffraction and filtering indicate that platinum-carbon rotary replication renders radially symmetrical contrast and 25 A resolution to freeze-etched specimens so as to clarify subunit structure...
