De Rham cohomology and homotopy Frobenius manifolds

, 2012
We endow the de Rham cohomology of any Poisson or Jacobi manifold with a natural homotopy Frobenius manifold structure. This result relies on a minimal model theorem for multicomplexes and a new kind of a Hodge degeneration condition.Comment: 11 pages ...

A Natural Lignification Inspired Super‐Hard Wood‐Based Composites with Extreme Resilience

Advanced Materials, EarlyView.
Super‐hard wood‐based composites (WBC) are designed and developed inspired by the mesoscale homogeneous lignification process intrinsic to tree growth. This innovative hybrid structure is achieved by leveraging the infusion of low‐molecular‐weight phenol formaldehyde resin into the cell walls of thin wood slices, followed by a unique multi‐layer ...

Capillary‐Driven 3D Open Fluidic Networks for Versatile Continuous Flow Manipulation

Advanced Materials, EarlyView.
The capillary‐driven 3D open fluidic networks (OFNs), composed of connected polyhedral frames, enable precise, programmable, and versatile manipulation of unary, binary, and multiple continuous flows in both spatial and temporal dimensions. OFNs represent a significant leap beyond conventional microfluidics, unlocking new possibilities for selective ...

Recent STAR Jet Results of the High-Energy Spin Physics Program at RHIC

, 2017
The production of jets from polarized proton+proton collisions at STAR is dominated by quark-gluon and gluon-gluon scattering. The dijet double spin asymmetry (A\tsub{LL}) is sensitive to the polarized gluon distribution ($\Delta g(x)$).

Multiplexed Bio‐detection on an Interferometric Optical Waveguide Assembly

Advanced Materials Interfaces, EarlyView.
Multiplexed remote bio‐detection is demonstrated through an image conduit composed of 3012 individual cores and coated with interferometric layers. The proof of concept of biodetection is performed through the kinetic monitoring of two complementary DNA strands hybridization paving the way for applications in multiplex in situ biosensing, and ...

Recent results from STAR for parton distribution functions at low and high $x$ in proton-proton collisions [PDF]

arXiv
According to perturbative quantum chromodynamic calculations, in $pp$ collisions at $\sqrt{s} = $~200 and 510 GeV studied at RHIC, jet production in mid-pseudorapidity, $|\eta| <$ 1, is dominated by quark-gluon and gluon-gluon scattering processes. Therefore jets at RHIC are direct probes of the gluon parton distribution functions (PDFs) for momentum ...

Profile of differentially expressed miRNAs in high-grade serous carcinoma and clear cell ovarian carcinoma, and the expression of miR-510 in ovarian carcinoma

Molecular Medicine Reports, 2015
Improved insight into the molecular and genetic profile of different types of epithelial ovarian cancer (EOC) is required for understanding the carcinogenesis of EOC and may potentially be exploited by future targeted therapies.
