A Miniaturized Metamaterial-Based Dual-Band 4×4 Butler Matrix With Enhanced Frequency Ratio for Sub-6 GHz 5G Applications

IEEE Access
This paper introduces an innovative $4 \times 4$ dual-band Butler matrix (BM) characterized by compactness and an enhanced frequency ratio (K). The design employs meandered lines and an interdigital capacitor (IDC) unit-cell-based composite right/left ...

Systematic Study of Separators in Air-Breathing Flat-Plate Microbial Fuel Cells—Part 2: Numerical Modeling

Energies, 2016
The separator plays a key role on the performance of passive air-breathing flat-plate MFCs (FPMFC) as it isolates the anaerobic anode from the air-breathing cathode.

Crossover from Reptation to Rouse dynamics in the Cage Model

, 2006
The two-dimensional cage model for polymer motion is discussed with an emphasis on the effect of sideways motions, which cross the barriers imposed by the lattice.

A rigorous measure of genome-wide genetic shuffling that takes into account crossover positions and Mendel’s second law

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance An important process in sexual organisms is the shuffling of maternal and paternal DNA in gametes by both crossing over and independent assortment of homologous chromosomes.

Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

Advanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...

Sequencing of Single Pollen Nuclei Reveals Meiotic Recombination Events at Megabase Resolution and Circumvents Segregation Distortion Caused by Postmeiotic Processes

Frontiers in Plant Science, 2017
Meiotic recombination is a fundamental mechanism to generate novel allelic combinations which can be harnessed by breeders to achieve crop improvement. The recombination landscape of many crop species, including the major crop barley, is characterized by

Structural Motifs in Soft Fibrous Tissues: Revealing Structure‐Mechanics Relationships in Deformation and Tear Resistance for Biomimetic Material Design

Advanced Healthcare Materials, EarlyView.
This review explores how soft fibrous tissues achieve their remarkable mechanical behavior through recurring structural motifs across multiple length scales. It highlights key advances in mimicking these features using fiber‐reinforced hydrogels and hierarchical composites, offering insights into mechanical compatibility, flaw tolerance, and tear ...

Superfluid density of states and pseudogap phenomenon in the BCS-BEC crossover regime of a superfluid Fermi gas

, 2010
We investigate single-particle excitations and strong-coupling effects in the BCS-BEC crossover regime of a superfluid Fermi gas. Including phase and amplitude fluctuations of the superfluid order parameter within a $T$-matrix theory, we calculate the ...
