This work presents RPM, a scalable anonymous communication protocol suite using secure multiparty computation (MPC) with the offline-online model. We generate random, unknown permutation matrices in secret-shared fashion and achieve improved (online) performance lightest overhead for clients compared to state of art robust protocols. Using square-lattice shuffling, we make our scale well as num...

Monodisperse beta-NaYF4:Yb,Tm nanocrystals with controlled size (25-150 nm), shape (sphere, hexagonal prism, and hexagonal plate), and composition (Yb: 20-40%, Tm: 0.2-5%) were synthesized from the thermolysis of metal trifluoroacetates in hot surfactant solutions. The upconversion (UC) of near-infrared light (980 nm) to ultra-violet (360 nm), blue (450 and 475 nm), red (650 and 695 nm) and inf...

Bulk Heterojunctions In article number 2206151, Xiaosheng Fang, Zhifeng Shi and co-workers develop a novel air induced formation of Cs3Bi2Br9/Cs3BiBr6 bulk heterojunction. Theoretical experimental characterization suggest that Cs3Bi2Br9 exhibits more stable structure in air. The heterojunction dual-band photodetection capabilities with UV main band (360 nm) peak responsivity 5.6 mA/W blue sub-b...

pyrolysis of low density polyethylene (ldpe) by equilibrium fluid catalytic cracking (fcc) was studied in a stirred reactor under different process parameters. in this work, the effect of process parameters such as degradation temperature (420-510°c), catalyst/polymer ratio (0-60%), carrier gas type (h2, n2, ethylene, propylene, ar and he), residence time and agitator speed (0-300 rpm) on the c...

The transport of living fish is an important part the farming process. usually causes stress. This study evaluated effects temperature and vibration frequency on water quality, blood biochemical parameters, gill histomorphology, oxidative stress, meat quality pearl gentian groupers after transport. First, 1-year-old (450 ± 25 g) were transported in plastic bags for 48 h, including following tre...
