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

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.

The ZmCOP1s–ZmCOL3 Module Enhances Late Flowering, Grain Yield and Grain Quality in Maize

Plant Biotechnology Journal, EarlyView.
ABSTRACT Flowering time is a key determinant of yield and regional adaptation in crops and is largely controlled by light signalling. In this study, we identified two maize orthologs of Arabidopsis CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1), designated ZmCOP1a and ZmCOP1b, which activate light signalling and reduce plant height. Loss‐of‐function mutants of

Biportal endoscopic foraminotomy of the L7–S1 neuroforamen in dogs: Description of surgical technique and ex vivo comparison with conventional open dorsolateral foraminotomy

Veterinary Surgery, EarlyView.
Abstract Objective (1) To establish a surgical technique for minimally invasive biportal endoscopic foraminotomy (BEF) of L7–S1 in dogs using arthroscopic equipment. (2) To compare BEF and dorsolateral foraminotomy (DF) and (3) to provide clinical results of the first client‐owned dog treated by way of BEF.

Mechanism of keyhole evolution and welding quality of electron beam welded magnesium alloy with scanning path variation via modeling and numerical study

Journal of Magnesium and Alloys
Welding quality of electron beam welded joint is usually susceptible to the stability of keyhole during welding process. The more stable the keyhole, the better the welding quality.

Microstructure and Fracture Behavior of Refill Friction Stir Spot Welded Joints of AA2024 Using a Novel Refill Technique

Metals, 2019
Keyhole at the end of a conventional friction stir welded (FSW) joint is one of the major concerns in certain applications. To address this issue, a novel keyhole refilling technique was developed for conventional friction stir spot welding (FSSW) using ...

Monitoring and Managing of Ergot Alkaloids in Cereal Grains: A Comprehensive Analysis of Analytical Challenges, Sampling Uncertainty, and Processing for Food Safety

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT Ergot alkaloids (EAs), toxic secondary metabolites produced by Claviceps purpurea, pose food and feed safety concerns for cereal grains, particularly rye and wheat. While EAs are most frequently associated with rye, their occurrence in other cereals has been increasingly reported across diverse regions.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.
