We present the mathematical foundation for a point-source method PSM to solve inverse electromagnetic perfect-conductor obstacle scattering problems. The PSM gives a new and explicit procedure how to compute locally from the far eld pattern E 1 an approximation for the total electric eld E near the unknown obstacle. The PSM then searches for the boundary of the obstacle as a zero-curve of p E w...

در این مقاله روشی نوین برای مدل‌سازی خطی پارامتر-متغیر (LPV) پلی‌تاپیک نامعین سیستم‌های قدرت بر اساس رویکرد نگاشت مجموعه پارامتر (PSM) بر پایه الگوریتم تحلیل مولفه‌های اصلی (PCA) ارائه شده است. ابتدا با خطی‌سازی معادلات سیستم حول مجموعه نقاطی از پاسخ گذرای دینامیکی، یک مدل LPV اولیه تولید می‌شود، سپس با به‌کارگیری تکنیک PSM برپایه الگوریتم PCA، تعداد مدل‌های خطی کاهش‌یافته و یک مدل پلی‌تاپیک کا...

We describe the production and characterisation of two monoclonal antibodies, zdc2 and zdd2, directed against the zebrafish Notch ligands DeltaC and DeltaD, respectively. We use our antibodies to show that these Delta proteins can bind to one another homo- and heterophilically, and to study the localisation of DeltaC and DeltaD in the zebrafish nervous system and presomitic mesoderm (PSM). Our ...

The Future Internet of Things (IoT) will connect billions of battery-powered radio-enabled devices. Some of them may need to communicate with each other and with Internet gateways (border routers) over multi-hop links. While most IoT scenarios assume that for this purpose devices use energy-efficient IEEE 802.15.4 radios, there are use cases where IEEE 802.11 is preferred despite its potentiall...

Somite formation in vertebrates depends on a molecular oscillator in the presomitic mesoderm (PSM). In order to get a better insight into how oscillatory expression is achieved in the zebrafish Danio rerio, we have analysed the regulation of her1 and her7, two bHLH genes that are co-expressed in the PSM. Using specific morpholino oligonucleotide mediated inhibition and intron probe in situ hybr...

PURPOSE The prognostic significance of positive surgical margins (PSM) in radical prostatectomy (RP) specimens remains unclear. While most studies have concluded that a PSM is an independent adverse prognostic factor, others report that surgical margin status has no effect on prognosis. One reason for these discordant conclusions is the variable number of patients with a PSM who receive adjuvan...

The life cycles of human papillomaviruses (HPVs) are intimately linked to the differentiation program of infected stratified epithelia, with both viral gene expression and replication being maintained at low levels in undifferentiated basal cells and increased upon host cell differentiation. We recently identified, in HPV-16, a negative regulatory element between the epithelial-cell-specific en...

OBJECTIVES We report on the development and psychometric properties of a scale to measure perceived sensitivity to medicines (PSM). Design.  The internal consistency, test-retest reliability, criterion-related, and predictive validity of the PSM Scale were evaluated using data collected as part of four previously published studies and one unpublished data set. METHODS Participants (n= 1,166) ...

Body skeletal muscles derive from the paraxial mesoderm, which forms in the posterior region of the embryo. Using microarrays, we characterize novel mouse presomitic mesoderm (PSM) markers and show that, unlike the abrupt transcriptome reorganization of the PSM, neural tube differentiation is accompanied by progressive transcriptome changes. The early paraxial mesoderm differentiation stages ca...

In the knowledge engineering field, models of expertise present interesting properties for reuse. In particular, Problem-Solving Methods (PSM), that identify generic lines of reasoning with specific uses of knowledge types, are good reusable components for knowledge modeling. In this paper we present a case study of PSM reuse, where we focus on two particular issues: (1) how to reuse a PSM by g...
