SUPRAORBITAL KEYHOLE CRANIOTOMY IN SURGERY OF INTRA- AND EXTRA-AXIAL BRAIN TUMORS

Опухоли головы и шеи, 2017
Background. Priority objectives of surgical neurooncology (diagnosis verification, tumor cytoreduction, and preservation of patient’s functional status) can be achieved both through traditional neurosurgical approaches and through the use of keyhole ...

On Outage Probability and Diversity-Multiplexing Tradeoff in MIMO Relay Channels [PDF]

, 2010
Fading MIMO relay channels are studied analytically, when the source and destination are equipped with multiple antennas and the relays have a single one. Compact closed-form expressions are obtained for the outage probability under i.i.d. and correlated

Frozen Differential Scattering in Reconfigurable Complex Media

Laser &Photonics Reviews, EarlyView.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

The Dependence of Properties on Structural Features in Macro/Micro Levels for PBF‐LB Fabricated Porous NiTi Alloy

Rare Metals, EarlyView.
ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

The access and invasiveness-based classification of medical procedures to clarify non-invasive from different forms of minimally invasive and open surgery

Journal of Minimal Access Surgery
Background: The rapid development of less invasive and traumatic medical procedures has resulted in a mixture of terms used to describe them, without any agreed definition for each.

Minimization of Porosity in E11018‐G Low‐Alloyed Steel Processed by Laser Powder Directed Energy Deposition

steel research international, EarlyView.
The processability of the E11018‐G by laser powder directed energy deposition (LP‐DED) is investigated. The effects of powder moisture, ambient humidity, and laser remelting on LP‐DED parts’ porosity are shown. A strong influence of the atomizing gas is observed.

‘The Good Couscous That Pleases Us!’: The Meanings of Enduring Imperialist Imagery in Postcolonial French Food Advertising, 1970–2000

Gender &History, EarlyView.
ABSTRACT This article examines a wave of Orientalism‐inspired food commercials that appeared on television in France between 1975 and 2000. Older commercials for couscous were more banal, emphasizing a given product's superiority or affordability. Around 1975, however, there was a concerted shift in the advertising; new spots contained exoticized ...
