This paper presents a nattiral extension of the new4 introdticed “anti-face” method to event detection, both in the image and in the feattire domains. In the caJe of the image domain (video segtience$ we create spatio-temporal templates by stacking the video framw, and the detection is pe formed on these templates. In order to recogzixe the motion of feattires in a video segtience, the spatial ...

The primary energetic processes driving the functional proton pump of bacteriorhodopsin take place in the form of complex molecular dynamic events after excitation of the retinal chromophore into the Franck-Condon state. These early events include a strong electronic polarization, skeletal stretching, and all-trans-to-13-cis isomerization upon formation of the J intermediate. The effectiveness ...

The photocycle and vibrational dynamics of bacteriorhodopsin in a lipid nanodisc microenvironment have been studied by steady-state and time-resolved spectroscopies. Linear absorption and circular dichroism indicate that the nanodiscs do not perturb the structure of the retinal binding pocket, while transient absorption and flash photolysis measurements show that the photocycle which underlies ...

BACKGROUND The aim of this study was assessment the risk management status of waste anesthetic gases in academicals hospitals in Iran to prevent from harmful effects of these gases on employees' health. METHODS A descriptive-analytic study was designed in 2011. Standard structured checklist developed by ECRI institute (Emergency Care Research Institute) was applied. Checklists were filled ons...

WINTER 2015 5 As George Bernard Shaw once observed, being slandered is better than being ignored. So maybe AI researchers should be happy about what’s been happening lately. After decades of pundits and philosophers arguing that AI is provably impossible, suddenly that argument has been replaced with the assertion that not only is it possible, but superhuman AI is so inevitable that it is the g...

Solid waste collection, transfer and transportation (SWCTT) is a fundamental component of solid waste management systems that contributes to both the costs and environmental emissions associated with managing solid waste. The objective of this study is to project the fuel consumption and fuel costs of SWCTT in Tehran from 2018 to 2032. A further objective is to evaluate the air pollutant emissi...

spliced and polyadenylated mRNA, and pre-mRNA tranEukaryotic cells must execute a complex program to scripts engineered to be synthesized by RNA polymergenerate mature functional messenger RNA (mRNA). ase III in mammalian cells fail to be spliced (Sisodia et After the transcription of a nuclear gene by RNA polyal., 1987). Greenleaf (1993) proposed that the negative merase II (RNA Pol II) is ini...

The Behavior Modification Program at the Humane Society of Boulder Valley addresses behavioral problems of dogs by using counter-conditioning, changing a stimulus from positive to negative, and desensitization, decreasing the emotional response to a stimulus, on a variety of behavioral issues. One of the most prevalent issues is food guarding and is addressed through the Food Care Protocol. The...

Both sexes of the turquoise-browed motmot, Eumomota superciliosa, display their long-racketed tail in an exaggerated side-to-side wag display in two contexts. In the first, the wag display is performed in the presence of predators (predator-elicited wag display), and evidence supports the hypothesis that the signal functions as a pursuit-deterrent signal (Murphy 2006, Behavioral Ecology, 17, 54...

Actin-based organelle movements are driven by the related multifunctional myosin motors of class V in animals and fungi and class XI in plants. The versatility of these motors depends critically on their C-terminal globular tail domain that allows them to bind to a broad variety of cargo molecules. Regulation of this motor-cargo attachment is frequently employed to modulate organelle movement. ...
