Using Computational Significance and Resilience in System Software Stacks.:Keynote Talk

This talk explores how the runtime system and operating system can leverage metrics that express the significance and resilience of application components in order to reduce the energy footprint of parallel applications. We will explore in particular how software can tolerate and indeed exploit higher error rates in future processors and memory technologies that may operate outside their safe margins.

Immunoglobulin heavy chain sequence analysis in Waldenstrom's macroglobulinemia and immunoglobulin M monoclonal gammopathy of undetermined significance.

In this study, we used IGH sequence analysis to assess the maturational status of Waldenstrom's (WM) macroglobulinemia and its putative precursor immunoglobulin (Ig)-M monoclonal gammopathy of undetermined significance (MGUS). IGH sequence analysis was performed using standard methods in 23 cases (20 WM and 3 IgM MGUS as defined by consensus panel criteria). Waldenstrom's macroglobulinemia cases were characterized by heavily mutated IGH genes (median, 6.3%; range, 3.8%-13.9%) but without intraclonal variation (ICV). IgM MGUS was similarly characterized by somatic hypermutation (median, 7.5%; range, 7%-7.7%), but ICV was evident in 1 of the 3 cases. We would therefore conclude that WM is characterized by somatic hypermutation without ICV, which supports a derivation from postgerminal center/memory B cells. IgM MGUS is also characterized by somatic hypermutation but, in a manner similar to IgA/IgG MGUS, can be associated with ICV, although the significance of this remains unclear.

Ki-67 Proliferation Index in Gastric Cancer - Biologic Significance

Objectives/Introdution: Ki-67 protein has been used as an indicator of proliferation activity in tumor cells. In gastric cancer the prognostic value has not been fully understood. This study was designed to assess the biologic significance of Ki-67 proliferation index (PI) in gastric cancer. Material/Methods: Seventy-two patients with gastric cancer were evaluated. These patients underwent gastric resection, and the tumor tissue was stained immunohistochemically. Ki-67 PI was defined as the percentage of tumor cells positive for Ki-67. Ki-67 PI was correlated with clinicopathological characteristics and patient survival. Results: A low Ki-67 PI (less than or equal to 50%) was associated with poorly differentiated histology - diffuse type (p=0.009) and signet ring cells (p=0.004) - and younger age (p=0.022). A worse prognosis in patients with low Ki-67 PI was also found (a mean survival of 41.8 vs 63 months for high Ki-67 PI group), but not statistically significant (p=0.623, log rank test). Discussion/Conclusion: We found an inversely correlation between Ki-67 PI and histological differentiation grade. Patients in group with low Ki-67 PI are younger, with poorly differentiated histology and have a lower mean survival. Like other studies already suggested, we may have two different tumors phenotypes - highly invasive with low proliferative capability, and less invasive potential with higher proliferative ability. However, in this sample, no significant prognostic value was achieved between both.

Population Health Facility - Determination of Significance and Request for Comments on Scope of SEIS

The University is considering a proposal for site selection and construction of a new above and below grade building to create a physical convening space and compelling catalyst for Population Health endeavors across all three UW campuses, the region, and the world, creating a high profile marker for the UW’s commitment to Population Health, as outlined in President Ana Man Cauce’s May 2016 address to the community.

Evaluating the conservation of graffiti based on cultural significance.

Purpose – Graffiti, both ancient and contemporary, could be argued to be significant and therefore worthy of protection. Attaching value is, however, subjective with no specific method being solely utilised for evaluating these items. The purpose of this paper to help those who are attempting to evaluate the merit of graffiti to do so, by determining “cultural significance”, which is a widely adopted concept for attaching value to the historic built environment. The current Scottish system utilised to assess “cultural significance” is the Scottish Historic Environment Policy (SHEP) which shares many common features with other determinants of cultural significance in different countries. The SHEP document, as with other systems, could however be criticised for being insufficiently sensitive to enable the evaluation of historic graffiti due, in part, to the subjective nature of determination of aesthetic value. Design/methodology/approach – A review of literature is followed by consideration of case studies taken from a variety of historical and geographical contexts. The majority of examples of graffiti included in this paper have been selected for their relative high profile, previous academic study, and breadth of geographic spread. This selection will hopefully enable a relatively comprehensive, rational assessment to be undertaken. That being said, one example has been integrated to reflect commonly occurring graffiti that is typical to all of the built environment. Findings – The determination of aesthetic value is particularly problematic for the evaluator and the use of additional art‐based mechanisms such as “significant form”, “self expression” and “meaning” may aid this process. Regrettably, these determinants are also in themselves subjective, enhancing complexity of evaluation. Almost all graffiti could be said to have artistic merit, using the aforementioned determinants. However, whether it is “good” art is an all together different question. The evaluation of “good” art and graffiti would have traditionally been evaluated by experts. Today, determination of graffiti should be evaluated and value attached by broader society, community groups, and experts alike. Originality/value – This research will assist those responsible for historic building conservation with the evaluation of whether graffiti is worthy of conservation.

Evaluating historic graffiti based on cultural significance and definitions of art.

Many examples of historic graffiti have been shown to be worthy of attention and conservation. The examples discussed in this article have been selected for their previous academic study, enabling rational assessment. This work does not suggest that only those examples of historic graffiti that have been subject to academic investigation can be evaluated and classified. This article, the result of a collaboration between two individuals with complementary interests in building conservation and contextual studies in art and design, brings together formal techniques used in the assessment of cultural significance in traditional architectural conservation and established theories in the evaluation of art. It is the purpose of this work to help those who are attempting to evaluate the merit of graffiti to do so. The current Scottish system that assesses cultural significance may be incomplete in its evaluation of graffiti. This necessitates a supplementary investigation of the artistic characteristics and merit of graffiti. Almost all graffiti could be said to be 'art', using established definitions, but not 'good' art. This evaluation may only be undertaken by experts, as with other aspects of identification of cultural significance within the built environment.

Pathological validation and significance of micrometastasis in sentinel nodes in primary breast cancer

In embracing a multidisciplinary approach to the management of patients with sentinel node biopsy in breast cancer, the pathologist task is to screen sentinel nodes for possible metastasis. The consequences of missing sentinel node micrometastasis can directly influence treatment strategies, and this screening therefore has to be performed with more attention than usual. There is presently great diversity in the histopathological work-up of sentinel nodes, with many centres employing additional techniques such as immunohistochemistry, reverse transcription polymerase chain reaction or flow cytometry in addition to routine haematoxylin and eosin staining. In this review, we address the pathological validation and significance of micrometastasis in sentinel node biopsy in primary breast cancer
