Resistive switching in optoelectronic III-V materials based on deep traps.

Resistive switching random access memories (ReRAM) are promising candidates for energy efficient, fast, and non-volatile universal memories that unite the advantages of RAM and hard drives. Unfortunately, the current ReRAM materials are incompatible with optical interconnects and wires. Optical signal transmission is, however, inevitable for next generation memories in order to overcome the capacity-bandwidth trade-off.

[Comparative drug therapy study with scintigraphic control research].

By means of the 99m-Tc-pertechnitate joint scintigraphy the authors try to document the effect of antirheumatic drugs in 62 patients with rheumatoid arthritis. By measuring the changes of the synovial blood circulation, conclusions are drawn as to the degree of inflammation. When trying to make a quantitative assessment of the changes of inflammation as compared with a standardised reference region, particularly on the wrist joint, it was found that the activity increased on the reference region on the forearm and that proved to be a possible source of error.

Comparative study of quantitating 99mTc-EHDP uptake in sacroiliac scintigraphy.

Quantitative sacroiliac (SI) scintigraphy was performed 3 h after an i.v. injection of 16 mCi 99mTc-EHDP.
