در این پروژه، دوزیمتری به روش سه بعدی ژل پلیمر با اضافه شدن نانوذرات طلا به ژل پلیمر magica انجام شد. همچنین با استفاده از کد محاسباتی mcnpx ژل پلیمر به منظور مقایسه با کار آزمایشگاهی شبیه سازی شد. ژل پلیمر ساخته شده در این طرح در محدوده ی دوز cgy 600-0 خطی است و قدرت تفکیک دوز کمتر از 7/0 گری دارد. با اضافه شدن نانوذرات طلا به قطر 50 نانومتر و با غلظت های mm 1/0، mm 2/0 و mm 4/0 به ژل پلیمر ma...

Bullet holes play a major role in the trajectory determination of fired bullets, potentially suggesting where shots were from. Few methods are currently employed to estimate angles incidence bullets using bullet holes. The literature has stressed that knowledge about impact behavior specific bullet–substrate interfaces, including most viable method for estimating angle combination, requires emp...

Locality-Constrained Discriminative Learning and Coding Report Title This paper explores the enhancement by locality constraint to both learning and coding schemes, more specifically, discriminative low-rank dictionary learning and auto-encoder. Previous Fisher discriminative based dictionary learning has led to interesting results by learning more discerning sub-dictionaries. Also, the low-ran...

Spectral properties of sign symmetric matrices are studied. A criterion for sign symmetry of shifted basic circulant permutation matrices is proven, and is then used to answer the question which complex numbers can serve as eigenvalues of sign symmetric 3 × 3 matrices. The results are applied in the discussion of the eigenvalues of QM -matrices. In particular, it is shown that for every positiv...

We consider classes of models related to those introduced by Lehmann in 1953 and Sklar in 1959. Recently developed algorithms for finding profile NP likelihood procedures are discussed, extended and implemented for such models by combining them with the MM algorithm. In particular we consider statistical procedures for a regression model with proportional expected hazard rates, and for transfor...

Ignition of Nanocomposite Thermites by Electric Spark and Shock Wave Report Title Nanocomposite 8Al ·MoO3 thermite particles were prepared using arrested reactive milling and ignited using two experimental techniques. In spark ignition, a monolayer of powder was placed on a conductive substrate and heated in air by a pulsed electrostatic discharge. In shock ignition, an individual particle was ...

Context. Unbiased molecular line surveys are a powerful tool for analyzing the physical and chemical parameters of astronomical objects and are the only means for obtaining a complete view of the molecular inventory for a given source. The present work stands for the first such investigation of a photon-dominated region. Aims. The first results of an ongoing millimeter-wave survey obtained towa...

Myeloid cell leukemia-1 (Mcl-1, HGNC: 6943), a pro-survival member of the Bcl-2 family, plays a crucial role in Multiple Myeloma (MM) pathogenesis and drug resistance, thus representing a promising therapeutic target in MM. A novel strategy to inhibit Mcl-1 activity is the induction of ubiquitin-independent Mcl-1 degradation. Our own and other previous studies have demonstrated caspase-dependen...
