Fix-lines and stability domain in the vicinity of the coupled third order resonance

open access: yes, 2015
The single particle stability in a circular accelerator is of concern especially for operational regimes involving beam storage of hours. In the proximity to a resonance this stability domain shrinks, and the phase space fragments into a jungle of exotic

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

cAMP Accumulation Assays Using the AlphaScreen® Kit (PerkinElmer)

open access: yesBio-Protocol, 2013
Cyclic adenosine monophosphate (cAMP) is an intracellular signaling messenger derived from the catalytic conversion of ATP, and is a major product of activated Gs protein-coupled receptors. Conversely, formation of cAMP is inhibited by Gi protein-coupled

A SNAP coupled microresonator delay line

open access: yesOptics Express, 2013
A delay line fabricated of a chain of SNAP (Surface Nanoscale Axial Photonics) coupled microresonators is demonstrated. In contrast to resonant delay lines demonstrated to date, the slow light in this structure is enhanced by the 2R (Rotation + Reflection) effect realized due to the 3D propagation of light along the surface of a SNAP fiber.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Nonreciprocal and magnetically scanned miniaturized leaky-wave antennas using coupled transmission lines

open access: yesEPJ Applied Metamaterials, 2014
This paper presents a new class of magnetically scanned leaky wave antennas (LWAs), incorporating ferrite (or possibly magnetoelectric composite), for wide angle beamsteering.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Design of a Broadband Band-Pass Filter with Notch-Band Using New Models of Coupled Transmission Lines

open access: yesThe Scientific World Journal, 2014
We intend to design a broadband band-pass filter with notch-band, which uses coupled transmission lines in the structure, using new models of coupled transmission lines.
