A significant challenge in systems engineering and acquisition is to justify investments in system flexibility as opposed to buying more features or copies of a less-flexible systems. The Total Ownership Cost (TOC) has the advantages of having clear cause-effect relationships that are easy to understand and reason about. We present two TOC models for valuing flexibility that have been calibrate...
(UV) light-induced skin damage. On the other hand, overexposure to UV radiation can lead to a pathological increase in melanin production. Epidermal hyper-pigmentation results from the increased activity of melanogenic enzymes such as tyrosinase. Tyrosinase oxidizes the conversion of L-tyrosine to 3,4-dihydroxyphenylalanine (DOPA) and DOPA to DOPA quinone, which are the first two rate limiting ...
In this issue of The Journal of Nuclear Medicine, Gabriel et al. (1) report their experience with 68Ga-labeled 1,4,7,10tetraazacyclododecane-N,N9,N99,N999tetraacetic acid-D-Phe1-Tyr3-octreotide (68Ga-DOTA-TOC) PET in a series of 84 patients with neuroendocrine tumors (NET). PET was more accurate with a higher detection rate than somatostatin receptor scintigraphy (using 111In-DOTA-TOC or 99mTc-...
A table-of-contents (TOC) provides a quick reference to a document’s content and structure. We present the first study on identifying the hierarchical structure for automatically generating a TOC using only textual features instead of structural hints e.g. from HTML-tags. We create two new datasets to evaluate our approaches for hierarchy identification. We find that our algorithm performs on a...
To evaluate the relationship between total organic carbon (TOC) and Rock-Eval S2 (petroleum potential) of petroleum source rocks, atotal of 180 outcrop samples from the black organic matter–rich facies of Mesozoic strata from a locality of southwest of Iran wereinvestigated using Rock-Eval VI pyrolysis and Leco Carbon Analyzer. The linear regression is applied to determine the correlationbetwee...
امروزه سازمان ها دریافته اند که برای بقا در محیط پرتلاطم پیرامون خود نیاز به برنامه ریزی استراتژیک دارند. می توان مدیریت استراتژیک را بدینگونه تعریف کرد "هنر و علم تدوین، اجرا و ارزیابی تصمیمات وظیفه ای چندگانه که سازمان را قادر می سازد به هدف های بلند مدت خود دست یابد" همانطور که از تعریف استنباط می شود فرآیند مدیریت استراتژیک در برگیرنده سه مرحله می باشد: تدوین استراتژی ها، اجرای استراتژی ها...
BACKGROUND There is a paucity of data on how to deliver complex interventions that seek to reduce the treatment gap for mental disorders, particularly in sub-Saharan Africa. The need for well-documented protocols which clearly describe the development and the scale-up of programs and interventions is necessary if such interventions are to be replicated elsewhere. This article describes the use ...
To explore whether differences in vitamin K nutrition might, at least in part, underlie differences in fracture incidence between Asian and European populations, the vitamin K status of older individuals in Shenyang, China (eighty-six men, ninety-two women) and in Cambridge, UK (sixty-seven men, sixty-seven women) was compared. Dietary information was collected by food questionnaire in Shenyang...
Nansi Lake has been seriously affected by intensive anthropogenic activities in recent years. In this study, an extensive survey on spatial variation, pollution assessment as well as the possible sources identification of major nutrients (Total phosphorus: TP, Total nitrogen: TN, and Total organic carbon: TOC) in the surface sediments of Nansi Lake was conducted. Results showed that the mean co...
Toc is an experimental programming language based on occam that combines CSP-based concurrency with integrated specification of timing requirements. In contrast to occam with strict round-robin scheduling, the Toc scheduler is lazy and does not run a process unless there is a deadline associated with its execution. Channels propagate deadlines to dependent tasks. These differences from occam ne...
