We develop a method to compute synthetic kilonova light curves that combines numerical relativity simulations of neutron star mergers and the $\texttt{SNEC}$ radiation-hydrodynamics code. describe our implementation initial boundary conditions, r-process heating, opacities for simulations. validate approach by carefully checking energy conservation is satisfied comparing results with those two ...
A subset of natural killer (NK) cells in normal mouse lymph node (LN) expresses CD127 (IL-7 receptor-α chain) and is thought to derive from the thymus. However, CD127(+) NK cells are found in the LN of athymic mice. Therefore, the origin of CD127(+) NK cells in the LN is unclear. Here, we have identified unique NK-cell progenitors (NKPs) in the LN that express the pan-NK cell marker CD49b and C...
زمینه و هدف: درد پس از تزریق عارضه شایع پروپوفول می باشد. پیشنهاد شده که نیتروگلیسیرین در همراهی با لیدوکائین می تواند در کاهش درد موثر باشد. هدف از این مطالعه مقایسه ترکیب لیدوکائین و نیتروگلیسیرین با لیدوکائین به تنهایی در تسکین درد ناشی از تزریق پروپوفول در بیماران تحت بیهوشی عمومی می باشد. مواد و روش کار: در یک کارآزمایی بالینی تصادفی دو سو کور، 90 بیمار در سه گروه دریافت کننده پلاسبو (گروه...
wych elm (ulmus glabra hudson) is one of the forest species in hyrcanian forests of iran and considered as threatened species due to its narrow ecological range, over-exploitation, as well as dutch elm disease. in order to evaluate the possibility of cryopreservation of ulmus glabra seeds for long-term preservation, seeds were collected from natural habitats and three pre-treatment methods incl...
Breast cancer is the most common site-specific cancer and is the second cause of mortality due to cancer in women. There are different prognostic factors including: axillary nodal status and tumor size(the most important factor), ER activity, PR, tumor grade and the type of histology. Other incompletely defined risk factors are: protease, catepstin, Her-2, etc. Her-2 is subtype 2 of E...
We consider a positive measure on [0,∞) and a sequence of nested spaces L0 ⊂ L1 ⊂ L2 · · · of rational functions with prescribed poles in [−∞, 0]. Let {φk}k=0, with φ0 ∈ L0 and φk ∈ Lk \ Lk−1, k = 1, 2, . . . be the associated sequence of orthogonal rational functions. The zeros of φn can be used as the nodes of a rational Gauss quadrature formula that is exact for all functions in Ln · Ln−1, a...
This study was undertaken to determine the roles of individual alpha/beta 1 integrin heterodimers in promoting cellular interactions with the different attachment-promoting domains of laminin (LN). To do this, antibodies to the integrin beta 1 subunit or to specific integrin alpha subunits were tested for effects on cell attachment to LN, to elastase fragments E1-4 and E1, derived from the shor...
Thermal processing of waste tyre and biomass through pyrolysis gasification provides a promising pathway to address issues raised by anthropogenic activities including energy security, management environmental sustainability. The study the kinetics underlying decomposition blend is an essential step understand their further reactions in reforming/cracking stage optimize use. Kinetics analysis t...
