Information Extraction from Single and Multiple Sentences
Some Information Extraction (IE) systems are limited to extracting events expressed in a single sentence. It is not clear what effect this has on the difficulty of the extraction task. This paper addresses the problem by comparing a corpus which has been annotated using two separate schemes: one which lists all events described in the text and another listing only those expressed within a singl...

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولSingle photons from coupled quantum modes: supplementary information
Assuming that the population remains small, one can truncate at given values of n1 and n2 to yield a finite set of differential equations. For an initial condition, we take the population to be zero, that is, ρ1,1,1,1 = 1 with all other elements of the density matrix set to zero. Eq. A.6 can then be solved numerically (we used the Adams-Moulton-Bashforth procedure) until a steady state is reach...
متن کاملComment on “ Extraction of work from a single thermal bath in the quantum regime ” Hal
In a recent Letter [1] Allahverdyan and Nieuwenhuizen presented a series of calculations on a quantum system coupled to a quantum heat bath, and made a rather sensational conclusion that the second law of thermodynamics may be violated as a “consequence of quantum coherence in the presence of the slightly off-equilibrium nature of the bath.” However, as we shall explain here, one can use the st...
