Physical, chemical and biological attributes of soil surface are significantly affected by tillage practices and crop rotation. The objective of this study was to determine the short-term (2006-2009) effects of conventional and conservational tillage practices on selected soil physical properties of a heavy clay soil under two wheat-corn and wheatlegume rotation in a semi-arid Mediterranean...

We study the one-shot zero-error classical capacity of quantum channels assisted by quantum no-signalling correlations, and the reverse problem of simulation. Both lead to simple semi-definite programmings whose solutions can be given in terms of conditional min-entropies. We show that the asymptotic simulation cost is precisely the conditional min-entropy of the ChoiJamiołkowski matrix of the ...

Gaussian processes (GP) are a widely used model for regression problems in supervised machine learning. Implementation of GP regression typically requires O(n) logic gates. We show that the quantum linear systems algorithm [Harrow et al., Phys. Rev. Lett. 103, 150502 (2009)] can be applied to Gaussian process regression (GPR), leading to an exponential reduction in computation time in some inst...

Soil seed banks were sampled in undisturbed soil and after soil had been disturbed by tillage (tine, harrow or plough). Seeds were sorted by size and shape, and counted. Size-number distributions were fitted by power law equations that allowed the identification of self-similarity and self-affinity. Self-affinity and thus non-random size-number distribution prevailed in undisturbed soil. Self-s...

objective(s) the aim of this study was to investigate the presence of per-1-type esbls in drug resistant pseudomonas aeruginosa isolates. materials and methods during one-year period (2008-2009), following isolation and identification of 56 p. aeruginosa, the e-test method was performed for determination of minimal inhibitory concentration of ceftazidim. the isolates that they had mic≥16 µg/ml ...

background and objective: early determination of antibacterial susceptibility increases the success of therapy, decreases unnecessary use of antibacterial agents and side-effects, and lowers the overall healthcare cost. materials and methods: a rapid colorimetric method for antibacterial susceptibility testing named qui-sensitest (inovative biotechnology organization, istanbul, turkey) was eval...

introduction: it has been shown that joint click, an initial and common finding in internal derangement (id), respond to neither conservative treatment nor surgical intervention. this raises the question as to whether it must be treated in the absence of other pertinent signs and symptoms, so the aim of this study was to investigate and compare the mri findings of tmj in both normal subjects an...
