Self‐Supervised Deep Learning Framework for Rician Distribution Based Denoising and Modeling of Multi‐b Prostate Diffusion MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Convolutional neural networks (CNNs) are evaluated for improved and accelerated denoising and Rician bias correction in multi‐b DW images with simultaneous signal modeling. Methods Prostate diffusion images from 46 individuals acquired at 20 linearly distributed b‐values (bmax=2000s/mm2)$$ {b}_{\mathrm{max}}=2000\kern0.3em \mathrm{s}/{\

Stein fillings of planar open books [PDF]

, 2015
We prove that if a contact manifold $(M,\xi)$ is supported by a planar open book, then Euler characteristic and signature of any Stein filling of $(M,\xi)$ is bounded.

Approximation of holomorphic mappings on strongly pseudoconvex domains

, 2009
Let D be a relatively compact strongly pseudoconvex domain in a Stein manifold, and let Y be a complex manifold. We prove that the set A(D,Y), consisting of all continuous maps from the closure of D to Y which are holomorphic in D, is a complex Banach ...

Stein complements in compact Kähler manifolds

Mathematische Annalen
Given a projective or compact K hler manifold X and a (smooth) hypersurface Y, we study conditions under which $X \setminus Y$ could be Stein. We apply this in particular to the case when X is the projectivization of the so-called canonical extension of the tangent bundle $T_M$ of a projective manifold M with Y being the projectivization of $T_M ...

Shifting the paradigm: An Indigenous knowledge‐based stewardship plan to replenish boreal caribou in Athabasca Chipewyan and Mikisew Cree First Nations' homelands

People and Nature, EarlyView.
Abstract Indigenous Peoples in northern Alberta, including Dené and Cree of the Athabasca Chipewyan and Mikisew Cree First Nations (ACFN and MCFN), have been using Indigenous laws and stewardship principles to care for their homelands for thousands of years. Since ACFN and MCFN signed Treaty 8 with Canada in 1899, Alberta's land management policies and

Eight lectures on Oka manifolds [PDF]

, 2015
Over the past decade, the class of Oka manifolds has emerged from Gromov's seminal work on the Oka principle. Roughly speaking, Oka manifolds are complex manifolds that are the target of "many" holomorphic maps from affine spaces.

The Hidden Costs of Coffee Production in the Eastern African Value Chains

Sustainable Development, EarlyView.
ABSTRACT There is increasing recognition that significant hidden costs associated with agrifood systems are not reflected in market prices. Coffee is among the three most traded agricultural commodities in the world and supports the livelihoods of more than 30 million smallholder households.

Stein manifolds M for which O(M) has the property Ω-tilda (Dedicated to Mikhail Mikhaylovich Dragilev on the occation of his 90th birthday) [PDF]

, 2013
In this note, we consider the linear topological invariant Ω-tilda for Fréchet spaces of global analytic functions on Stein manifolds. We show that O(M), for a Stein manifold M, enjoys the property Ω-tilda if and only if every compact subset of M lies ...

Lefschetz fibrations on compact Stein surfaces

, 2000
The existence of a positive allowable Lefschetz fibration on a compact Stein surface with boundary was established by Loi and Piergallini by using branched covering techniques.
