By using twist construction, we obtain a quantum groupoid D⊗qUqg for any simple Lie algebra g. The underlying Hopf algebroid structure encodes all the information of the corresponding elliptic quantum group-the quasi-Hopf algebras as obtained by Fronsdal, Arnaudon et. al. and Jimbo et. al..

A cross section of a human population (501 individuals) selected at random, and living in a Bolivian community, highly endemic for Chagas disease, was investigated combining together clinical, parasitological and molecular approaches. Conventional serology and polymerase chain reaction (PCR) indicated an active transmission of the infection, a high seroprevalence (43.3%) ranging from around 12%...

We consider a general class of boundary terms of the open XYZ spin-1/2 chain compatible with integrability. We have obtained the general elliptic solution of K-matrix obeying the boundary Yang-Baxter equation using the R-matrix of the eight vertex model and derived the associated integrable spin-chain Hamiltonian. 1+1 dimensional integrable models with boundaries find interesting applications i...

This research combines a phosphor-in-glass (PiG) YAG:Ce3+ with red liquid-type quantum dot (LQD) to invent high-quality white light-emitting diodes (WLEDs). When the PiG LQD-built WLEDs reach 100 mA, they provide heated illumination offering an outstanding color rendering index (CRI) (Ra=93.9, R9=97.7, and R13=98.1). The luminescent efficiency (LE) correlating chromatic temperature, correspondi...

Many countries shift substantial public resources across jurisdictions to mitigate spatial economic disparities. We use a general equilibrium model with multiple asymmetric regions, labor mobility, and costly trade carve out the aggregate implications of fiscal transfers. Calibrating for Germany, we find that transfers indeed deliver smaller disparities regions. This comes at cost lower nationa...

The article demonstrates a sample of spectrum in the phosphor-covered WLED (abbreviated as p-WLED) containing one blue chip, red chip along with phosphors green and yellow colors. We acquired p-WLEDs’ ideal CCTs, which is short for correlated color temperature range from 2700 K to 6500 using nonlinear program order optimize radiation’s lumen efficiency (LER) when R9 strong red's rendering index...

In this work, we firstly introduce notions of principal directed curves and donor which are associated a Frenet curve in the dual Lorentzian space D 3 1 D13 . We give some relations between curvature torsion curve. show that general helix is plane obtain equation by using position vector Then circle $\mathbb{D}^{2}$ or hyperbola $\mathbb{D}_{1}^{2}$ slant $\mathbb{D}_{1}^{3}$ helix, respectivel...

In this paper analytical study has been made to investigate a hybrid refrigerant consists of different refrigerants with mixing ratios and find out its effects on the performance cycle specify best that gives least environmental pollution. Firstly vapor compression refrigeration system analyzed several pure refrigerants( R11, R12, R13,R22,R23, R32, R41, R115, R116, R124, R125, R134a, R142a, R14...
