Hyperloss from coherent spatial-mode mixing in quantum-correlated networks [PDF]

Nature Communications
Quantum-correlated networks distribute quantum resources such as squeezed and entangled states. They are central to modern quantum technology, including photonic quantum computing, quantum communications, biological sensing and gravitational-wave ...

Evaluation of mismatch power loss in a PV string composed of series-connected modules: Theory versus experiment

Ain Shams Engineering Journal
Ground-installed PV power-systems are usually built in parallel-rows; each is composed of series-connected modules. With time, some modules got-polluted or −shaded differently. On damage, some modules may be replaced by others of different ratings.

Power Enhancement in Partial Shaded Photovoltaic System Using Spiral Pattern Array Configuration Scheme

IEEE Access, 2021
Partial shading causes mismatch losses in the solar PV system. In the PV array, the power output from the healthy PV modules is gone in vain due to the mismatch losses.

L-Shape Propagated Array Configuration With Dynamic Reconfiguration Algorithm for Enhancing Energy Conversion Rate of Partial Shaded Photovoltaic Systems

IEEE Access, 2021
Partial shading is an unavoidable factor that reduces the performance of solar PV systems. The PV system receives uneven irradiation due to partial shading which causes the mismatch loss.

Performance and Reliability Improvement of Partially Shaded PV Arrays by One-Time Electrical Reconfiguration

IEEE Access, 2022
Partial shading is the most unexpected scenario encountered by the arrays that degrade the performance causing power reduction, non-convex characteristics curves, losses, hotspot, module damage, and system failure. The adoption of various reconfiguration

Impact of Uneven Shading by Neighboring Buildings and Clouds on the Conventional and Hybrid Configurations of Roof-Top PV Arrays

IEEE Access, 2021
Partial shading is the commonly encountered scenario of building roof-top based PV arrays that mainly occur due to the shadow of the neighbouring buildings and clouds resulting in unexpected losses and deteriorated system performance.

A Scalable Hierarchical Dynamic PV Array Reconfiguration under Partial Shading

Energies, 2023
Photovoltaic (PV) arrays are often affected by partial shading (PS), which can significantly reduce their power output. Dynamic reconfiguration is a promising technique for mitigating the negative effects of PS by adjusting the electrical connections of ...

Information Loss Associated with Imperfect Observation and Mismatched Decoding [PDF]

Frontiers in Computational Neuroscience, 2011
We consider two types of causes leading to information loss when neural activities are passed and processed in the brain. One is responses of upstream neurons to stimuli being imperfectly observed by downstream neurons. The other is upstream neurons non-optimally decoding stimuli information contained in the activities of the downstream neurons.
