High-Rate Space Coding for Reconfigurable 2x2 Millimeter-Wave MIMO Systems

open access: yes, 2015
Millimeter-wave links are of a line-of-sight nature. Hence, multiple-input multiple-output (MIMO) systems operating in the millimeter-wave band may not achieve full spatial diversity or multiplexing.

Highly Reproducible, Vendor‐Agnostic, Motion‐Insensitive Liver PDFF Mapping at 0.55T, 1.5T, and 3T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and validate a vendor‐agnostic, motion‐insensitive proton‐density fat‐fraction (PDFF) quantification method. Methods Flip‐angle‐modulated (FAM) 2D chemical‐shift‐encoded (CSE) MRI for PDFF quantification was implemented in both the vendor‐agnostic platform Pulseq (“Pulseq‐FAM”) and one vendor‐specific platform (“GE‐specific ...

High Rate/Low Complexity Space-Time Block Codes for 2x2 Reconfigurable MIMO Systems

open access: yes, 2015
In this paper, we propose a full-rate full-diversity space-time block code (STBC) for 2x2 reconfigurable multiple-input multiple-output (MIMO) systems that require a low complexity maximum likelihood (ML) detector. We consider a transmitter equipped with

Plant secondary metabolites as a model for drug development [PDF]

open access: yes, 2018
Biljni sekundarni metaboliti su spojevi koji nisu nužni za rast i razvoj biljaka, ali im omogućavaju prilagodbu i preživljavanje u okolišu. Strukturna kompleksnost i raznolikost sekundarnih metabolita osigurala im je važnu ulogu u farmaceutskoj ...

Floral trait similarity at the community‐level increases reproductive success suggesting facilitation through pollinator sharing

open access: yesOikos, EarlyView.
The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...

Unveiling human–wildlife interactions in the context of livestock grazing abandonment and the return of large carnivores, ungulates and vultures: A stakeholder perspective

open access: yesPeople and Nature, EarlyView.
Abstract Pastoral practices remain a widespread economic activity across European mountain regions. However, the viability of this activity may be threatened by the recovery of large wild vertebrates associated with passive rewilding, leading to the so‐called human–wildlife conflicts.
