We propose a new gradient method for quadratic programming, named SDC, which alternates some SD iterates with some gradient iterates that use a constant steplength computed through the Yuan formula. The SDC method exploits the asymptotic spectral behaviour of the Yuan steplength to foster a selective elimination of the components of the gradient along the eigenvectors of the Hessian matrix, i.e...

In this study, the authors tested the cultural transmission of vocal traditions in cowbirds (Molothrus ater). Young cowbirds from a South Dakota (SD) population were housed over winter with adults of the SD population or with adults from an Indiana (IN) population. Song differences between the original SD and IN adult models were acquired by South Dakota culture (SDC) and Indiana culture (INC) ...

Fast Fourier transform (FFT) has played a significant role in digital signal processing field, especially in the advanced communication systems, such as orthogonal frequency division multiplexing (OFDM) and asymmetric digital subscriber line. An efficient combined single-path delay commutator-feedback (SDC-SDF) radix-2 pipelined fast Fourier transform architecture, which includes log 2 − 1 SDC ...

Network clustering is an important technique used in many large-scale distributed systems. Given good design and implementation, network clustering can significantly enhance the system's scalability and efficiency. However, it is very challenging to design a good clustering protocol for networks that scale fast and change continuously. In this paper, we propose a distributed network clustering ...

Gene-specific and chromosome-wide mechanisms of transcriptional regulation control development in multicellular organisms. SDC-2, the determinant of hermaphrodite fate in Caenorhabditis elegans, is a paradigm for both modes of regulation. SDC-2 represses transcription of X chromosomes to achieve dosage compensation, and it also represses the male sex-determination gene her-1 to elicit hermaphro...

Statistical Agencies are faced with increasing demands by users to release more detail and high quality statistical data. This requires examining the trade off between managing disclosure risk below tolerable thresholds and disseminating “fit for purpose” data with as much information as possible. In particular, protecting Census data containing whole population counts is one of the greatest SD...

Salivary duct carcinoma (SDC) is a distinctive and aggressive neoplasm. The most frequent site of origin is the parotid gland, followed by the submandibular gland. SDC originating in the minor salivary glands, particularly in the ectopic glands within the mandible, is extremely rare. We describe a 62-year-old man with SDC in the mandible, who presented with a painless lump in the right submandi...

This report presents a case of salivary duct carcinoma (SDC) responding to multiple lines of androgen blockade, including a rapid response to abiraterone. This case represents the first published report of SDC responding to abiraterone and illustrates that androgen receptor expressing SDC may be treated with multiple lines of androgen blockade, including newer agents such as abiraterone. The Oh...

The present paper focuses on evaluating the interobserver reliability of the 'Welfare Quality(®) Animal Welfare Assessment Protocol for Growing Pigs'. The protocol for growing pigs mainly consists of a Qualitative Behaviour Assessment (QBA), direct behaviour observations (BO) carried out by instantaneous scan sampling and checks for different individual parameters (IP), e.g. presence of tail bi...

The electrochemical behavior of chemical vapor deposition (CVD) grown porous films of Sm-doped ceria (SDC) for hydrogen oxidation has been evaluated by impedance spectroscopy using a point contact geometry at a temperature of 650 °C. Porous SDC films, 950 nm in thickness, were deposited on both sides of single-crystal YSZ(100). Pt paste was applied over the surface of one SDC layer to create a ...
