Optimized Wide-Angle Metamaterial Edge Filters: Enhanced Performance with Multi-Layer Designs and Anti-Reflection Coatings

Photonics
This study presents a systematic optimization of wide-angle metamaterial long-pass (LP) edge filters based on silicon nanospheres (SiNP). Multi-layered configurations incorporating SiNP-meta-films and anti-reflection coating (ARC) elements not previously

Polypropylene – zinc oxide nanorod hybrid material for applications in separation processes

Chemical and Process Engineering, 2016
Hybrid filter material was obtained via modification of polypropylene (PP) nonwoven with nanosize zinc oxide particles of a high aspect ratio. Modification was conducted as a three-step process, a variant of hydrothermal method used for synthesis of nano-

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Circular prediction algorithms-hybrid filters [PDF]

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2003
The focus of the paper is on the development of a geometric algorithm as an alternative to the coordinated turn procedures. The fact that the trajectories of maneuvering targets are always smooth has been exploited to derive an algorithm, which constrains the predicted position of the target to lie on a circle formed by prior measurements.

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells

FEBS Open Bio, EarlyView.
Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Hybrid Active Power Filter Connected to a Photovoltaic Array [PDF]

Journal of Electrical and Electronics Engineering, 2009
The existence of nonlinear loads in the utility has been increasing at an unprecedented pace in recent years. These types of loads draw non-sinusoidal currents from the mains, causing harmonic distortion.

Power hybrid filter

TECNIA, 2007
This article shows the simulation results obtained from the study of a power electronic system, which significantly improves the performance of the conventional three-phase passive filter that is normally used for power factor compensation of non-linear loads.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Input filters for THD minimization and power factor improvement in rectifier-fed systems: A review

Franklin Open
Rectifiers are widely used in modern electronic equipment and electrical power systems (EPS) and constitute one of the primary sources of harmonic currents in distribution networks. These harmonics can distort the voltage at the point of common coupling (

Filtering in hybrid dynamic Bayesian networks [PDF]

2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004
We demonstrate experimentally that inference in a complex hybrid dynamic Bayesian network (DBN) is possible using the 2-time slice DBN (2T-DBN) from (D. Koller et al., Sequential Monte Carlo Methods in Practice: p.445-464, Springer-Verlag, NY, 2000) to model fault detection in a watertank system.
