An algorithm for network-based gene prioritization that encodes knowledge both in nodes and in links
No full textBackground: Candidate gene prioritization aims to identify promising new genes associated with a disease or a biological process from a larger set of candidate genes. In recent years, network-based methods - which utilize a knowledge network derived from biological knowledge - have been utilized for gene prioritization. Biological knowledge can be encoded either through the network's links or nodes. Current network-based methods can only encode knowledge through links. This paper describes a new network-based method that can encode knowledge in links as well as in nodes. Results: We developed a new network inference algorithm called the Knowledge Network Gene Prioritization (KNGP) algorithm which can incorporate both link and node knowledge. The performance of the KNGP algorithm was evaluated on both synthetic networks and on networks incorporating biological knowledge. The results showed that the combination of link knowledge and node knowledge provided a significant benefit across 19 experimental diseases over using link knowledge alone or node knowledge alone. Conclusions: The KNGP algorithm provides an advance over current network-based algorithms, because the algorithm can encode both link and node knowledge. We hope the algorithm will aid researchers with gene prioritization. © 2013 Kimmel, Visweswaran
Subrings of K[y1, …, yt] of the type D + I
No full textAbstractIn this paper we consider the affine domain R = K[y1, …, y1] (where K is a field) having krull dimension n > 0 and subrings of R of the form S = D + I (where D is a subring of K and I is a nonzero proper ideal of R). In Section 1 we characterize when S is Noetherian. In Section 2 we determine when S is a Zero-divisor ring and when S is a Laskerian ring. We prove in Section 3 that S is a strong S-ring if and only if D is a strong S-ring and K is algebraic over D. We determine in Section 4 when S is an N-ring
Prime divisors of powers of ideals in some Laskerian rings
No full textAbstractLet R be a Noetherian domain. Let I be a nonzero proper ideal of R such that for all prime ideals Q associated to the ideal I, the associated graded ring of R with respect to Q is an integral domain. Let S be a subring of R such that I is contained in S and S/I is a zero-dimensional Laskerian ring. Then for any proper ideal B of S there exists a positive integer ‘m’ depending on B, such that the set of associated prime ideals of Bn for any n ≥ m equals the set of associated prime ideals of Bm

Laskerian pairs
No full textAbstractFor a commutative ring T with identity and a subring R of T containing the identity element of T, (R, T) is called a ‘Laskerian pair’ (LP) resp. a ‘strongly Laskerian pair’ (SLP) if every ring A with R ⊆ A ⊆ T is Laskerian (resp. strongly Laskerian). In Section 1 we characterize when (R, R[X]) is an LP where R is a ring and X is an indeterminate over R. In Section 2, necessary and sufficient conditions are determined in order that (R, K) is an LP where K is a field containing R. For an integral domain R, we answer in Section 3 when (R, S-1R) is an LP where S is a multiplicatively closed subset of R with 0 S. In Section 4, we characterize when (K, R) is an LP where R is an affine ring over a field K. For an LP (R, T) we determine in Section 5 relations between the Krull dimensions of R and T
Wideband FM demodulation by injection-locked division of frequency deviation
No full textA novel and useful wideband FM demodulator operating across an 8 GHz IF bandwidth for application in low-power, wideband heterodyne receivers. The demodulator includes an n-stage ring oscillator that is injection locked to a wideband input signal. Locking to the input frequency, it divides the FM deviation by n, thereby facilitating as well as reducing the energy required for wideband demodulation. The quadrature-phased output of the ring oscillator is auto correlated using a low-power folded CMOS mixer capable of detecting FM up to 400 Mb/s over a 2-10 GHz IF frequency range.MicroelectronicsElectrical Engineering, Mathematics and Computer Scienc

Going Into labor: (un)making mothers in India's transnational surrogacy markets
No full textIn this study, I am concerned with the practices of representation and labor control that enable the extraction of value from the bodies of working class women in India’s transnational surrogacy markets. Recent ethnographic studies on transnational surrogacy in India have conceptualized surrogacy as a form of waged labor and focused on critically examining the structure of surrogacy markets and the production of mother-workers. This study builds on these ethnographic approaches towards surrogacy as labor, and analyzes the discourses and the practices of labor control that enable service providers to extract value from the women’s bodies; a large part of this value accrues from their treatment as disposable. I begin by analyzing the discourses around surrogate mothers in three key sites of representation, that is, the news media, service provider websites and the draft legislation that is set to regulate the use of assisted reproductive technologies in India. Subsequently, I critically examine my interactions with service providers in New Delhi to unearth the mechanisms of disciplining and surveillance that are used to control, discipline and ensure productivity of the surrogate labor. My findings suggest that surrogate mothers are always framed within the competing discourses of “exploitation” and “empowerment” in the press, while the service providers represent them within the frames of “opportunity”. In the draft legislation, the rights of surrogate mothers are based on the market-based assumptions about reproductive autonomy and the disposability of working class women’s bodies. A critical examination of my interactions with service providers, and their recruitment and disciplining strategies, reveals the ways by which labor is effectively disciplined and controlled for value extraction. Thus, this study highlights some of the ways by which working class women’s labor is exploited and their bodies are treated as disposable. Future studies should attend to the ways in which the surrogate mothers experience these practices that they are subject to and whether, or not, disrupt the production of the “ideal” mother-worker.Women's and Gender Studie

Renu village : an ethnography of north Indian fiction
No full texttextThe Hindi author Phanishwarnath Renu (1921-1977) is credited with initiating the “regional” literary genre in India—a form characterized in part by its use of village song and performance. Renu's work is unusual for the deep debt it owes to his village's performance community; he described himself as a product of folksong, and there are hundreds of textual examples of village song in his writing. Both the songs performed in Renu's village, and also those performed in his fiction, are products of sensibilities local to the folklore region of northeast Bihar. This dissertation draws on textual analysis and on fieldwork in Renu's village, Aurahi-Hingana, and uses a performative approach to explore this Hindi author's unusual station on the border of written and oral tradition.
Renu was no passive reproducer of song, but a performer himself, and for certain individuals in his village Renu was a singer first and writer second. Some illiterate village singers even claim him as one of their own. He had a direct hand in shaping the life of his community's folklore as a singer and teacher, and his influence is such that he has become a character within the twenty-first-century village performance repertory. If Renu was a performer, then there is something to be gained from considering his writing as a performance category. The songs in his writing inhabit space, geography, and history—they are worldly—in the same way that live performances of village song inhabit the world. This dissertation proposes a contrapuntal method of reading both fiction and performance that demonstrates the multi-layered complexity of one of Hindi's much-loved authors, and affirms the many layers, the complexity, and the importance of the song tradition to which that author belonged.Asian Studie
HERMES Radio: Energy and Spectral Efficient Transmitter architectures for small satellites
No full textAs the complexity of nanosatellite missions have increased over time, the data generated on-board nanosatellites have increased multiple folds. As a result, there is a need to downlink large amounts of data. Multiple nanosatellite missions have started using spectral efficient modulation schemes recommended in DVB.S2 and DVB.S2X to make the best use of the available spectrum. One of the main challenges in adopting higher order modulation schemes is to power-efficiently upconvert and amplify the baseband signals. All the lost efficiency in converting the DC power to the RF output is dissipated as heat and the relatively small thermal mass of nanosatellites poses thermal management challenges. As a first step to addressing the challenge of improving the power efficiency of the communication module, optimization techniques to improve the Peak to Average Power Ratio (PAPR) of the modulation schemes (16/32-APSK) are discussed in this paper. The PAPR of 16-APSK reduces by ~2 dB by incorporating filtering techniques discussed in this paper. Further, a well-known efficiency and linearity enhancement technique; Out-phasing/LINC (Linear Amplification using Non-linear Components) is discussed. As a variant of the out-phasing architecture, a novel approach is proposed using two circularly polarized antenna to transmit the constant envelope signals in opposite polarizations and signal combining is performed at the receiver. Simulations results are used to demonstrate how higher efficiencies can be achieved using the proposed architecture.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic
