Abstract Imaging Cherenkov detectors form the backbone of particle identification (PID) at future Electron Ion Collider (EIC). Currently all designs for first EIC detector proposal use a dual Ring CHerenkov (dRICH) in hadron endcap, Detector Internally Reflected (DIRC) light barrel, and modular RICH (mRICH) electron endcap. These involve optical processes with many photons that need to be track...

Using a fluid treatment, it is shown that electrostatic waves with angular frequencies ~ ωci (ion cyclotron frequency) propagating at large angles to the ambient magnetic field can be excited in a magnetized plasma by perpendicular shear in the magnetic field aligned plasma flow. The role of density gradients in determining the stability of sheardriven EIC modes is also considered. PACS numbers...

To resolve the long-standing discrepancy between precision measurement of bottom quark forward-backward asymmetry at LEP/SLC and Standard Model prediction, we propose a novel method to probe $Zb\bar{b}$ coupling by measuring single-spin $A_e^b$ polarized lepton cross section in neutral current DIS processes with $b$-tagged jet HERA EIC. Depending on tagging efficiency final state $b$-jet, can a...

The solution structures of free Enzyme I (EI, ∼128 kDa, 575 × 2 residues), the first enzyme in the bacterial phosphotransferase system, and its complex with HPr (∼146 kDa) have been solved using novel methodology that makes use of prior structural knowledge (namely, the structures of the dimeric EIC domain and the isolated EIN domain both free and complexed to HPr), combined with residual dipol...

In chloroplasts of plants the xanthophyll cycle is suggested to function as a protection mechanism against photodamage. Two enzymes catalyze this cycle. One of them, violaxanthin de-epoxidase, transforms violaxanthin (Vio) to zeaxanthin (Zea) via antheraxanthin (Anth) and is bound to the lumenal surface of the thylakoid vesicles, when being in its active state. The other enzyme, Zea-epoxidase, ...

In this paper, an ontology-driven approach for the semantic analysis of video is proposed. This approach builds on an ontology infrastructure and in particular a multimedia ontology that is based on the notions of Visual Information Object (VIO) and Multimedia Information Object (MMIO). The latter constitute extensions of the Information Object (IO) design pattern, previously proposed for refin...

The fact that many famous denizens of Rijeka belong to different nationalities confirms this city's historic multicultural image. The life story of Erik Vio (1910-1966), renowned surgeon of international reputation, reflects the fate of many displaced residents of Rijeka who left to live in exile. After graduating in Rome, Vio worked as a medical doctor in Hong Kong for almost three decades. Th...
