A Swarm of Bs

New physics signals containing five or more b-tagged jets, but without MET or leptons, could realistically be sitting within the current 8 TeV LHC data set without receiving meaningful constraints from any of the existing LHC searches at either ATLAS or CMS. This work provides several examples of simple, motivated models that yield final states containing many b-jets. To study the potential for uncovering new physics in these high b-jet multiplicity channels, this paper focuses on a natural supersymmetry scenario where each of the pair-produced stops decays to an on-shell chargino, which subsequently decays via an MFV-motivated, R-parity violating coupling. This gives rise to an eight-jet final state containing six b-quarks. Although no public measurements exist, estimates indicate that the standard model backgrounds in high b-jet multiplicity channels should be very small. To circumvent the background uncertainty, an asymmetric method is presented that utilizes two different techniques to conservatively exclude or to discover new physics in high b-jet multiplicity final states.Comment: 14 pages, 4 figures, 2 tables, journal versio

Diurnal and Seasonal Activity of Female Mutillids on a Michigan Sand Flat (Hymenoptera: Mutillidae)

Diurnal activity of mutillid females of a southwestern Michigan sand area was characterized in relation to sand surface temperature conditions. Seasonal abundance patterns weredetermined for four Dasymutilla species

NICMOS Observations of Luminous and Ultraluminous Infrared Galaxies

HST NICMOS observations of a sample of 24 luminous (LIGs: L_(IR) [8-1000 microns] = 10^(11.0-11.99) L_sun) and ultraluminous (ULIGs: L_(IR) > 10^(12.0) L_sun) infrared galaxies are presented. The observations provide, for the first time, high resolution HST imaging of the imbedded 1.1 - 2.2 micron nuclear regions of these mergers. All but one of the ULIGs are observed to have at least one compact (50-200 pc) nucleus, and more than half contain what appear to be blue star clusters. The warm infrared galaxies (i.e., the transition sources) are observed to have bright nuclei which account for most of the light of the galaxy. This, combined with the tendency for the light of ULIGs to become more centrally concentrated as a function of increasing wavelength, implies that most of their energy is generated within a region 50-200 pc across.Comment: LaTex, 6 pages with 1 postscript and 1 jpg figure, and 1 postscript table, To appear in the proc. of the Ringberg workshop on "Ultraluminous Galaxies: Monsters or Babies" (Ringberg castle, Sept. 1998), Ap&SS, in pres

Eulogy to Architecture: The Three-Dimensional Collage City of Nostalgia

In our time of existence on the Earth, human beings have designed and realized beautiful things. As we face the challenges that confront us today, we begin to understand the fragility of humankind’s creations. Many of the world’s cities and buildings lie in ruins, gazed at by tourists, studied by scholars, while more lie buried in the ground for hundreds of years, some never to be rediscovered. Everything around us is an accumulation of knowledge and ideas built upon for centuries, now facing questionable circumstances. Of course, the more recent Aleppo and other Middle Eastern cities have fallen subject to bombings over the past years, now lost forever. Climate change threatens coastal cities around the world; natural disasters unexpectedly take from our grasp things that we have had for centuries. Nothing is for certain. Nothing lasts forever. Every built structure, no matter the value, eventually falls. What if the earth is one day no longer ours? Its livelihood depends on us, and our sustained wars and climatic abuse continue to decay the soil we walk on and the air we breathe. Will humans be forced from the planet that we have forever called home? This project imagines a new world built on the framework of nostalgia. It is a eulogy to architecture, a compilation of fragments of our world to recreate a place once lost. The city is designed as a three-dimensionalization of Rowe’s Collage City so as to create an assemblage of parts that form a whole. Various scales of fragments of earth, ranging from single buildings to neighborhood fabrics, are arranged in a volumetric space. This space is located away from the gravitational pull of the Earth, making it possible to collage fragments vertically as well as horizontally. The city embraces both the beauty and imperfections of the collected places. To call it a utopia is forward, considering that the majority of each of the employed places were not originally designed as utopian; thus one cannot project utopianism upon them simply because they have a diĐerent context. One might question how an organic system of organization could ever be considered utopian, considering the lack of planning. However, if utopianism is based on the perfection of the human itself rather than the environment, this city aims to imbue a sense of nostalgia in each human mind, with the idea that these places are inherently important to us as a species and to our connection to Earth itself. This project is a visual essay about the importance of what humans have created for themselves on the Earth. It is a conceptual idea that aims to transcend fears of loss by giving hope for a new world collaged from existing fragments of built fabric

Methodologies for the Automatic Location of Academic and Educational Texts on the Internet

Traditionally online databases of web resources have been compiled by a human editor, or though the submissions of authors or interested parties. Considerable resources are needed to maintain a constant level of input and relevance in the face of increasing material quantity and quality, and much of what is in databases is of an ephemeral nature. These pressures dictate that many databases stagnate after an initial period of enthusiastic data entry. The solution to this problem would seem to be the automatic harvesting of resources, however, this process necessitates the automatic classification of resources as ‘appropriate’ to a given database, a problem only solved by complex text content analysis. This paper outlines the component methodologies necessary to construct such an automated harvesting system, including a number of novel approaches. In particular this paper looks at the specific problems of automatically identifying academic research work and Higher Education pedagogic materials. Where appropriate, experimental data is presented from searches in the field of Geography as well as the Earth and Environmental Sciences. In addition, appropriate software is reviewed where it exists, and future directions are outlined

Asthma management: an ecosocial framework for disparity research

Background: Asthma management disparities (AMD) between African and White Americans are significant and alarming. Various determinants have been suggested by research frameworks that affect the unfair distribution of resources for asthma management to groups who are more or less advantaged socially. Ecosocial models organize determinants into individual/family, healthcare, community, and sociocultural levels. Multilevel interventions can affect AMD through simultaneous actions on different levels and pathways between determinants. Objective: Provide a comprehensive summary of the known determinants of AMD. Method: Peer reviewed research frameworks of AMD from 1998-2009 were retrieved from PubMed/ Web of Science databases using (“Socioeconomic Factors”[Mesh] OR (“Healthcare Disparities”[Mesh] OR “Health Status Disparities”[Mesh])) AND “Asthma”[Mesh] AND “African Americans”[Mesh] OR “Ethnic Groups”[Mesh]). Abstracts assessed for a focus on AMD, and determinants. Articles were analyzed for ecosocial levels and determinants. Results: 13 research frameworks described 34 determinants. Compared to other levels, Individual/family levels had the most emphasis, and frameworks using healthcare and community levels were the most narrow in focus. Stress, poverty, violence/crime, quality of care, healthcare access, and indoor air quality were well described determinants. Conclusions: Multilevel investigations should include those well described determinants of AMD and increase knowledge of pathway interactions between healthcare and community levels
