Crystal Melting and Wall Crossing Phenomena
This paper summarizes recent developments in the theory of Bogomol'nyi-Prasad-Sommerfield (BPS) state counting and the wall crossing phenomena, emphasizing in particular the role of the statistical mechanical model of crystal melting. This paper is divided into two parts, which are closely related to each other. In th…
Numerical calculation of near field scalar diffraction using angular\n spectrum of plane waves theory and FFT
t is a known fact that near field diffraction or Fresnel diffraction\ncalculations are difficult to perform exactly. It is in general necessary to\nmake some approximations in order to obtain a more suitable form. In this work,\na numerical implementation based on angular spectrum theory for near field\ndiffraction is…

Boundary effects on the end-to-end distance statistics of confined semiflexible polymers
The constraints imposed by nano- and microscale confinement on the conformational degrees of freedom of thermally fluctuating biopolymers is utilized in contemporary nano-devices to specifically elongate and manipulate single chains. A thorough theoretical understanding and quantification of the statistical conformati…

Estudo da dependência da condutividade com a microestruturade ligas Cu-Ni com diferentes dopagens
Copper and its alloys have various applications from manufactured artefacts to sophisticated equipments and stands out as conductive material due to high electrical and thermal conductivity. Its mechanical properties are moderate, as high corrosion resistance, high ductility. The choice of copper as a study material w…
Chapter Coated poultry products
Introduction The consumption of chicken and turkey meat has increased dramatically over the last seve ral decades. This increase in consumption can be attributed to the marketing and innovation of the poultry industry. Value-added processing is a term that means adding convenience and variety for the consumer while in…
NIF Target Assembly Metrology and Results
Abstract not provided
Report of the Bulk Working Group
The world in general and the USA in particular are facing an oncoming energy shortage. One key mechanism to provide carbon-free energy is nuclear fission. At this point, 20% of the US electrical power grid is supplied by nuclear energy. (Interestingly, it is 50% in Illinois.) European nations such as Sweden (50% nucle…

Highly conductive boron‐doped hydrogenated microcrystalline silicon films obtained by hot wire deposition
Abstract The growth of highly conductive boron doped microcrystalline silicon by the hot wire method was studied. Various series of films were deposited to investigate the influence of the deposition parameters on conductivity, crystallinity and (void‐related) microstructure. Maximum (room temperature) conductivities…
Finite Element Analysis and Damage Indices for Flexural Behavior of Rural Concrete Composites
In this article, finite element analysis using commercial software ANSYS 10 for rural fibrous concrete composite beams under flexural static loading is presented. Also damage indices for different fibrous beams under flexural cyclic loading are obtained using the available simple damage index formula. Rural fibers suc…
Investigation of CO2 insertion into lanthanide amides, alkoxides, and mixed amide/alkoxides
A novel set of lanthanide (Ln) alkoxycarbonates, [Ln(μ-CO2-DBP)(DBP)2]2 where Ln = lanthanide; and DBP = OC6H3-2,6-C(CH3)3, were isolated from a systematic study of the insertion of CO2(g) (referred to as CO2) into the Ln-O bonds of a series of new lanthanide alkoxides, Ln(OR)3. This study was undertaken to determine…
Recent advancements in technology of compact laser plasma EUV sources
The recent advancements in technology of compact laser plasma EUV sources based on a gas puff target are presented in the paper. The sources have been developed for application in processing materials using EUV radiation in the wavelength range from about 5 nm to about 50 nm that is efficiently produced in result of i…
Reinvestigation of KMg1/3Nb2/3OPO4
The crystal structure of potassium magnesium niobium oxide phosphate, KMg(1/3)Nb(2/3)OPO(4), which was described in the space group P4(3)22 [McCarron & Calabrese, (1993 ▶). J. Solid State Chem.102, 354-361], has been redetermined in the revised space group P4(1). Accordingly, the assignment of the space group P4(3)22…

Nano-aquarium fabrication with cut-off filter for mechanism study of Phormidium assemblage
We demonstrate fabrication of microfluidic chips integrated with different functional elements such as optical filters and optical waveguide for mechanism study of gliding movement of Phormidium to a seedling root using a femtosecond (fs) laser. Fs laser direct writing followed by annealing and successive wet etching…
FE based online model for the prediction of work roll thermal profile in hot strip rolling
Prediction and control of the thermal deformation of the work roll is vital for enhancing product quality in hot strip and plate rolling. In this paper, the authors present an online model for the prediction of the work roll thermal profile. The model is developed on the basis of an integrated finite element model for…
A large pulmonary arteriovenous malformation: a classical scenario
A huge pulmonary arteriovenous malformation (PAVM) presenting with a classical triad of cyanosis, polycythemia and clubbing of the fingers in a 12-year-old boy was confirmed on spiral computed tomography (CT) angiography. Considering the lesion size, central location and its large feeding and drainage vessels, the pat…
