We demonstrate a projection lithography method that induces optical index changes in a flexible polymer cable that is continuously translated through the image plane. We demonstrate that a static spot pattern generates a grid of waveguides along the cable length via a continuous extrusion process. Rotations or scaling of the optical spot array can fabricate image inverters or magnifying face pl...

primary sedimentary and secondary structural and diagenetic processes are responsible for heterogeneity in carbonate reservoirs and recognition of these factors is very essential subject in modeling these reservoirs. image logs are very useful for identification of structures and small scale sedimentary features. in this research, using image analysis of formation microimager log (fmi) in a dri...

Optimizing water injection rate distribution in waterflooding operations is a vital reservoir management aspect since capacities may be constrained due to geographic location and facility limitations. Traditionally, numerical grid-based simulation used for waterflood performance evaluation prediction. However, the approach can time-consuming expensive with vast amount of wells data mature field...

The essential mechanisms and virulence factors enabling Brucella species to survive and replicate inside host macrophages are not fully understood. The authors previously reported that a putative guanosine 5'-diphosphate 3'-diphosphate (ppGpp) mutant (spoT mutant) of Brucella abortus failed to replicate in HeLa cells. The present study showed that the pattern of surface proteins and morphologic...

We present surface temperature maps for the FK Comae-type star HD 199178 (V1794 Cygni) calculated from high resolution spectra obtained in 1994 and 1995. The spot pattern evolves, but all maps reveal a large cool spot remaining nearly at the same high latitude. The main spot is 1200 – 1600 K cooler than the mean surface temperature. The observed slightly flat bottomed absorption lines would usu...

In the petroleum industry, artificial intelligence has been applied in seismic and logging interpretation, accurate modeling, optimized drilling operations, well dynamics prediction, safety warning, etc. However, field-scale application deployment remain a challenge due to lack of sufficiently powerful algorithms for integration multi-granularity data time space domain, construction deep-learni...
