Molecular dynamics （MD） computer simulation techniques, as a powerful tool commonly utilized by the liquid crystal display （LCD） community, usually are employed for computing the equilibrium and transport properties of a classical many body system, since they are very similar to real experiments in many respects. In this paper we pre- sent molecular dynamics computer simulation results taken for a mixture of the two different kinds of nematic liq- uid crystals （LCs）. We calculated rotational viscosity from Brownian behavior with friction of the mean director of the mixture comprising pentylcyanobiphenol （5CB） and decylcyanobiphenol （10CB） by using molecular dynamics computer simulation, where intermolecular potential parameter is Generalized AMBER force field （GAFF）. Our computed results show a good agreement with the experimental results.

Spatial distributions of plasma parameters such as electron density, electron temperature and electric potential were investigated using a commercial simulation software （COMSOLTM） to predict the effects of antenna configuration in a large area inductively cou- pled plasma （ICP） system for flat panel displays. Nine planar antenna sets were evenly placed above a ceramic window. While the electron density was influenced by both the input current and gas pressure, the electron temperature and electric potential were dominantly affected by the gas pressure.

Dear Editor,I am Dr. Jungyul Park from the Division of Oculoplasty, Department of Ophthalmology, Pusan National University Hospital, Busan, Korea. I am writing to present a case of direct approach to thrombosed superior ophthalmic vein of recalcitrant indirect carotid cavernous fistula which was failed to treat with multiple conventional embolization treatment. To our knowledge this is very challenging procedure to the ophthalmologist, and not well described in literatures, especially in thrombocythemia patient with thrombosed superior ophthalmic vein.

A rational design of efficient low-band-gap non-fullerene acceptors(NFAs)for high-performance organic solar cells(OSCs)remains challenging;the main constraint being the decrease in the energy level of the lowest unoccupied molecular orbitals(LUMOs)as the bandgap of A-D-A-type NFAs ***,the short current density(J_(sc))and open-circuit voltage(V_(oc))result in a trade-off relationship,making it difficult to obtain efficient ***,three NFAs(IFL-ED-4 F,IDT-ED-4 F,and IDTT-ED-2 F)were synthesized to address the above-mentioned issue by introducing 3,4-ethylenedioxythiophene(EDOT)as aπ-*** NFAs exhibit relatively low bandgaps(1.67,1.42,and 1.49 eV,respectively)and upshifted LUMO levels(-3.88,-3.84,and-3.81 eV,respectively)compared with most reported low-band-gap ***,the photovoltaic devices based on IDT-ED-4 F blended with a PBDB-T donor polymer showed the best power conversion efficiency(PCE)of 10.4%with a high J_(sc) of 22.1 mA cm^(-2) and Voc of 0.884 V among the examined *** contrast,IDTT-ED-4 F,which was designed with an asymmetric structure of the D-p-A type,showed the lowest efficiency of 1.5%owing to the poor morphology and charge transport properties of the binary ***,when this was introduced as the third component of the PM6:BTP-BO-4 Cl,complementary absorption and cascade energy-level alignment between the two substances could be ***,the IDTT-ED-4 F-based ternary blend device not only improved the Jscand Voc,but also achieved a PCE of 15.2%,which is approximately 5.3%higher than that of the reference device with a minimized energy loss of 0.488 *** addition,the universality of IDTT-ED-2 F as a third component was effectively demonstrated in other photoactive systems,specifically,PM6:BTPe C9 and PTB7-Th:IEICO-4 *** work facilitates a better understanding of the structure–property relationship for utilizing efficient EDOT-bridged NFAs in high-performance OSC applications.

We consider a class of n-dimensional Pompeiu equations and that of Pexider equations and their Hyers Ulam stability problems in the spaces of Schwartz distributions. First, reducing the given distribution version of functional equations to differential equations we find their solutions. Secondly, using approximate identities we prove the Hyers Ulam stability of the equations.

Our previous study evaluated the in vitro and in vivo antioxidant activities of sulfated polysaccharides from a Celluclastassistedextract of Hizikia fusiforme (HFPS). The results indicate that HFPS possesses potent antioxidant activity and suggestthe potential use of HFPS to combat photoaging. In this study, we investigated the ultraviolet (UV) protective effect of HFPSin vitro in keratinocytes (HaCaT cells) and in vivo in zebrafish. The results indicate that HFPS significantly reduced thelevel of intracellular reactive oxygen species (ROS) and improved the viability of UVB-irradiated HaCaT cells. In addition,HFPS remarkably decreased apoptosis formation in UVB-irradiated HaCaT cells in a dose-dependent manner. The in vivotest results also demonstrate that HFPS significantly reduced intracellular ROS levels, cell death, NO production, and lipidperoxidation levels in UVB-irradiated zebrafish in a dose-dependent manner. These results suggest that HFPS possessesstrong in vitro and in vivo UV-protective effects, making it a potential ingredient in the cosmeceutical industry.
