A Novel Multi-Gene Detection Platform for the Analysis of miRNA Expression

open access: yesScientific Reports, 2018
The study of miRNAs and their roles as non-invasive biomarkers has been intensely conducted in cancer diseases over the past decade. Various platforms, ranging from conventional qPCRs to Next Generation Sequencers (NGS), have been widely used to analyze ...

Covariant and heavy quark symmetric quark models [PDF]

open access: yesPhysical Review D, 1994
There exist relativistic quark models (potential or MIT-bag) which satisfy the heavy quark symmetry (HQS) relations among meson decay constants and form factors. Covariant construction of the momentum eigenstates, developed here, can correct for spurious center-of-mass motion contributions.Proton form factor and M1 transitions in quarkonia are ...

Positive magnetoresistance induced by hydrodynamic fluctuations in chiral media

open access: yesJournal of High Energy Physics, 2021
We analyze the combined effects of hydrodynamic fluctuations and chiral magnetic effect (CME) for a chiral medium in the presence of a background magnetic field. Based on the recently developed non-equilibrium effective field theory, we show fluctuations

Measurement of the W boson polarization in top quark decays with the ATLAS detector [PDF]

open access: yes, 2012
This paper presents measurements of the polarization of W bosons in top quark decays, derived from tt− events with missing transverse momentum, one charged lepton and at least four jets, or two charged leptons and at least two jets.

Search for medium response to jet quenching via hadron chemistry around the quenched jets [PDF]

open access: yesEPJ Web of Conferences
We present a unique signal of medium response to jet quenching: the enhancement of baryon-to-meson ratios for associated particles at intermediate transverse momentum around the triggered quenched jets.

The colour of quarks [PDF]

open access: yesPhysics Letters B, 1996
It is shown that colour can only be defined on gauge invariant states. Since the ability to associate colour with constituent quarks is an integral part of the constituent quark model, this means that, if we want to extract constituent quarks from QCD, we need to dress Lagrangian quarks with gluons so that the result is gauge invariant.

Hierarchical Organization of Biomaterials in the Formation of Photonic Nanostructures

open access: yesAdvanced Science, EarlyView.
Natural organisms create vibrant structural colors through precisely organized nanostructures formed under mild biological conditions. This review explores how cellulose, chitin, corneous beta‐protein, and melanin form complex nanostructures across molecular, mesoscale, and tissue levels.
