Scaling up MIMO: Opportunities and Challenges with Very Large Arrays [PDF]

open access: yes, 2012
This paper surveys recent advances in the area of very large MIMO systems. With very large MIMO, we think of systems that use antenna arrays with an order of magnitude more elements than in systems being built today, say a hundred antennas or more ...

Improving the Characteristics of the Direct FOC Strategy in DFIG‐Based Wind Turbine Systems Using FOIDD and FOPD Controllers

open access: yesEnergy Science &Engineering, Volume 14, Issue 2, Page 999-1021, February 2026.
This study presents a new control strategy for doubly fed induction generator (DFIG) wind turbine systems to overcome the limitations of traditional direct field control using proportional‐integral (DFOC‐PI) regulators, which are sensitive to coefficient changes and lead to low power quality.

DPC-Net: Deep Pose Correction for Visual Localization

open access: yes, 2018
We present a novel method to fuse the power of deep networks with the computational efficiency of geometric and probabilistic localization algorithms. In contrast to other methods that completely replace a classical visual estimator with a deep network ...

Distinct 5′ UTR Requirements for Translation of the Bicistronic X/P mRNA Among Avian Orthobornaviruses

open access: yesMicrobiology and Immunology, Volume 70, Issue 2, Page 80-90, February 2026.
ABSTRACT Orthobornaviruses express X and the phosphoprotein (P) from a bicistronic X/P mRNA, and these proteins regulate polymerase activity. In mammalian orthobornaviruses, the 5′ untranslated region (5′ UTR) of the X/P mRNA controls the translational balance between X and P and thereby promotes efficient replication.

Physical Proximity With Social Support Regulates Vigilance to Threat: Evidence From Startle Reactivity During Emotional Stress Induction

open access: yesPsychophysiology, Volume 63, Issue 2, February 2026.
ABSTRACT Access to social support during emotional stress is one of the most important factors for the successful regulation of stress‐induced psychophysiological activation, and is predictive of improved health and well‐being. In this research we wanted to deepen our understanding of this buffering effect, focusing on the modulation of the startle ...
