Abstract Coherent optical memories will likely play an important role in future quantum communication networks. Among the different platforms, based on ladder-type orbital transitions atomic gasses offer high bandwidth (>100 MHz), continuous (on-demand) readout, and low-noise operation. Here we report upgraded setup of our previously-reported fast ladder memory, with improved efficiency life...

In this paper, in order to improve the efficiency of dye-sensitized solar cells, we introduced zirconia [ZrO2] nanofibers into a mesoporous titania [TiO2] photoelectrode. The photoelectrode consists of a few weight percent of ZrO2 nanofibers and a mesoporous TiO2 powder. The mixed ZrO2 nanofibers and the mesoporous TiO2 powder possessed a larger surface area than the corresponding mesoporous Ti...

In this paper, we analyze the statistical properties of school test scores and explore the implications for the design of school accountability systems. Using data from North Carolina, we decompose the variance of school-level test scores into a persistent component, sampling variation and other non-persistent shocks. We find that sampling variation and other nonpersistent components of school ...

This study aims to determine the genetic variance and heritability of yield component agronomic character some new plant type (NTP) rice genotypes planted on two different locations. The research was arranged in randomized complete block design (RCBD) with 12 treatments three replications as a blok nested location (in locations, i.e.: East Lampung Tanggamus. treatment consisted 10 genotypes, IP...
