Searching for high-redshift centimeter-wave continuum, line and maser emission using the Square Kilometer Array

We discuss the detection of redshifted line and continuum emission at radio wavelengths using a Square Kilometer Array (SKA), specifically from low-excitation rotational molecular line transitions of CO and HCN (molecular lines), the recombination radiation from atomic transitions in almost-ionized hydrogen (radio recombination lines; RRLs), OH and water maser lines, as well as from synchrotron and free-free continuum radiation and HI 21-cm line radiation. The detection of radio lines with the SKA offers the prospect to determine the redshifts and thus exact luminosities for some of the most distant and optically faint star-forming galaxies and active galactic nuclei (AGN), even those galaxies that are either deeply enshrouded in interstellar dust or shining prior to the end of reionization. Moreover, it provides an opportunity to study the astrophysical conditions and resolved morphologies of the most active regions in galaxies during the most active phase of star formation at redshift z~2. A sufficiently powerful and adaptable SKA correlator will enable wide-field three-dimensional redshift surveys at chosen specific high redshifts, and will allow new probes of the evolution of large-scale structure (LSS) in the distribution of galaxies. The detection of molecular line radiation favours pushing the operating frequencies of SKA up to at least 26 GHz, and ideally to 40 GHz, while very high redshift maser emissions requires access to about 100 MHz. To search for LSS the widest possible instantaneous field of view would be advantageous.Comment: 12 pages, 2 figures. To appear in "Science with the Square Kilometer Array," eds. C. Carilli and S.

Realizing the Technical Advantages of Star Transformation

Data warehousing and business intelligence go hand in hand, each gives the other purpose for development, maintenance and improvement. Both have evolved over a few decades and build upon initial development. Management initiatives further drive the need and complexity of business intelligence, while in turn expanding the end user community so that business change, results and strategy are affected at the business unit level. The literature, including a recent business intelligence user survey, demonstrates that query performance is the most significant issue encountered. Oracle\u27s data warehouse 10g.2 is examined with improvements to query optimization via best practice through Star Transformation. Star Transformation is a star schema query rewrite and join back through a hash join, which provides extensive query performance improvement. Most data warehouses exist as normalized or in 3rd normal form (3NF), while star schemas in a denormalized warehouse are not the norm . Changes in the database environment must be implemented, along with agreement from business leadership and alignment of business objectives with a Star Transformation project. Often, so much change, shifting priorities and lack of understanding about query optimization benefits can stifle a project. Critical to the success of gaining support and financial backing is the official plan and demonstration of return on investment documentation. Query optimization is highly complex. Both the technological and business entities should prioritize goals and consider the benefits of improved query response time, realizing the technical advantages of Star Transformation

Development of a Desktop Reference for Medication Assisted Treatment (MAT)

This project was to develop a physician desktop reference to assist with medication assisted treatment (MAT) for opioid use disorder. It was developed in conjunction with MAT team members and family medicine physicians to serve as a reference of both commonly needed medical information and local contact information for community resources.https://scholarworks.uvm.edu/fmclerk/1594/thumbnail.jp

The Impact of the Participation Rate - Whatever it is -on University Enrolment

In the period from 1960 to 1976 the participation rate in university education increased dramatically and has since fallen. During this same period the size of the university age group doubled, so there was a period of great expansion in university enrolment. Popula- tion projections show a decline of the order of 20% in the size of the university age group between 1982 and 1996, and many believe that university enrolments must inevitably drop too, although the participation rate will be a major determinant of what happens. The factors which influence participation rates using the period 1960 to 1978, and the way in which participation rates are measured are examined. This is then applied to a discussion of the level of undergraduate enrolment in the period to 1996.De 1960 à 1976 le taux de participation dans les études universitaires a augmenté d'une manière spectaculaire. Depuis lors il est tombé. Pendant cette même période le nombre de la population en âge de fréquenter l'Université a doublé, de façon qu 'il y a eu une grande augmentation dans les inscriptions. Les études qui ont été faites sur la population montrent qu 'entre 1982 et 1996 il y aura une diminution de l'ordre du 20% dans le nombre des per-sonnes qui ont l'âge requis pour fréquenter l'Université. Par conséquent, l'on croit que les inscriptions doivent inévitablement diminuer aussi, bien que le taux de participation soit le facteur déterminant de ce qui arrive. Les facteurs qui influencent les taux de participa-tion pendant la période de 1960 à 1978 et le mode de calcul des taux de participation sont examinés. Ceci, par la suite, fait l'objet d'une discussion sur le niveau d'inscription aux études sousgraduées dès maintenant à 1996

THE ANGULAR DEPENDENCE OF ACOUSTIC SCATTERING STATISTICS FOR ROCKY SEAFLOORS

Understanding the performance of automatic detection algorithms requires a thorough understanding of the physical processes that affect the acoustic scattering statistics of sonar imagery. Many studies have reported on the scattering statistics of the seafloor generally, and recent work has quantified the dependence of scintillation index (SI) on range for sandy seafloors. This study examined the angular dependence of acoustic scattering statistics for rocky seafloors, which display complex spatial texture. Synthetic aperture sonar (SAS) images of rocky outcrops near Bergen, Norway, were categorized by texture and analyzed using scintillation index, relative scattering strength, and mixture model parameters with respect to grazing angle. The different rock textures displayed distinct scattering statistics across all methods of analysis. SI was generally found to increase with decreasing grazing angle and scattering strength was found to increase with increasing grazing angle, though variation was seen between textures. A three component model was found to perform the best for the smooth and weathered/pitted textures whereas a four component model performed the best for the stepped texture. All textures were best represented by less complex models at higher grazing angles, consistent with studies conducted on sandy seafloors. SAS imagery was provided by the Norwegian Defence Research Establishment.Distribution Statement A.
