Molecular logic gates are capable of performing various logic tasks for biomarker detection, disease diagnostics and therapy, and controlling biological progress. Herein, we integrated multiple components of a logic device into a single DNA 3D nano-assembly with a triangular prism structure. Compared with the separate construction of each component in previously reported DNA logic gate systems,...

The GS (Genetic Selection) Principle states that biological selection must occur at the nucleotide-sequencing molecular-genetic level of 3'5' phosphodiester bond formation. After-the-fact differential survival and reproduction of already-living phenotypic organisms (ordinary natural selection) does not explain polynucleotide prescription and coding. All life depends upon literal genetic algorit...

An attempt has been made to use low-voltage alternating current to kill microorganisms such as Escherichia coli. The bactericidal effect depends on the energy passing through the suspension and on the time during which the cells are left standing in the medium after the treatment. Most of the toxicity is due to an indirect effect developed with unalterable electrodes in the presence of chloride...

This correspondence points out that the scope of application of the matrix model for MOS complex gates proposed by El.ziq and Su' does not cover general structures of this type. Also, an example is given to show that a complete detection test set for single stuck-at faults may not be able to detect all multiple faults in a fanout-free and irredundant MOS complex gate. Index Terms -Fault detecti...

(i) A 59-year-old Caucasian male presented at the casualty department complaining of pricking in the right eye. Symptoms were caused by a marginal infiltrate and this resolved on conventional therapy. A recurrence one month later also responded well. Each cornea presented an arcus senilis and, in the zone ofstroma affected by the arcus, an additional opacity could be seen. This was identical in...

Introduction Customary dissection in the Physical Therapy Anatomy Laboratory yielded a unilateral left-sided scapular ligament variation in a single cadaver. The embalmed specimen was a 58-year-old Caucasian male. The primary finding was a variant ligament which spanned across the supraspinous fossa in inferior to superior orientation. The suprascapular nerve and artery were seen passing under ...

administrative regulations for water flow decrease distribution efficiency and effect the economical operation of irrigation networks. complications in distribution systems and the decrease in availability of water require study of the hydraulic performance of existing flow control structures. control systems designed by neyrpic (zayandeh rud network) and usbr (doroodzan network) were investiga...
