Jet substructure as a new Higgs search channel at the LHC

It is widely considered that, for Higgs boson searches at the Large Hadron Collider, WH and ZH production where the Higgs boson decays to b anti-b are poor search channels due to large backgrounds. We show that at high transverse momenta, employing state-of-the-art jet reconstruction and decomposition techniques, these processes can be recovered as promising search channels for the standard model Higgs boson around 120 GeV in mass.Comment: 4 pages, 3 figure

Economic and Fiscal Impacts of Proposed LNG Facility in Robbinston, Maine

The purpose of this study is to examine the economic and fiscal impacts of the proposed Downeast LNG facility on the Town of Robbinston, Washington County, and the State of Maine. The economic impact analysis focuses on the employment and income that are associated with the LNG facility construction and operations. The fiscal impact analysis considers additional local and state tax revenues associated with the facility, as well as increased local government expenditures that are projected to result from the LNG project. This report does not address the environmental, homeland security, or energy security impacts of the LNG facility. In addition, this report does not estimate any changes in the price of delivered natural gas in Maine that could potentially result from a new major energy supplier

Jet substructure as a new Higgs search channel at the Large Hadron Collider

We show that W H and Z H production where the Higgs boson decays to bbbar can be recovered as good search channels for the Standard Model Higgs at the Large Hadron Collider. This is done by requiring the Higgs to have high transverse momentum, and employing state-of-the-art jet reconstruction and decomposition techniques.Comment: Talk presented by J.M.Butterworth at 34th International Conference on High Energy Physics, ICHEP08, Philadelphia, July 200

The Effect of Poststenotic Vessel Wall Compliance upon the Pulsus Tardus Phenomenon

Recent studies have investigated the detection of significant arterial stenoses through identification of the "pulsus tardus" phenomenon in Doppler waveforms obtained distal to the stenosis. The etiology of this phenomenon, however, has not yet been determined. Using an in vitro model based upon an electrical circuit analogy, the authors had as their objective to determine whether the compliance of the vessel wall immediately distal to a stenosis, in conjunction with the stenosis, is the cause of pulsus tardus. For a constant stenosis, it was found that the degree of pulsus tardus, as quantitated by the acceleration index, increased as the compliance of the poststenotic segment increased. It is concluded that pulsus tardus distal to an arterial stenosis is likely due to the compliance of the normally distensible artery, in conjunction with the stenosis. Pathological conditions that alter the compliance of the poststenotic segment may affect the degree of pulsus tardus, perhaps limiting its usefulness for upstream stenosis detection.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68136/2/10.1177_000331979404500703.pd

Sustainable Transportation for Maine’s Future

Maine is dependent on its transportation infrastructure for continued economic strength and growth, particularly on the 22,670 miles of public roads. Maine ranks fourteenth in the nation for the largest number of highway miles traveled annually per capita - 14,912 per year. Maine is highly reliant on its road system because large areas of the State lack transportation alternatives. This means that the current and future condition of the roadways is a major concern. How such a crucial infrastructure will continue to be supported and enhanced financially to meet the growing needs of the State must be considered carefully

The application of ultrasound during brain surgery

The use of intraoperative, real-time ultrasound imaging during intracranial neurosurgical procedures is described. This technique has proven to be extremely useful for localization of a wide variety of deep and superficial brain lesions, and for needle biopsy or aspiration of selected lesions. The precise localization provided by ultrasonic imaging shortens the time of surgery and increases the safety for the patient . Every type of primary and metastatic tumor of the brain has imaged well, and low-grade gliomas are often better defined with ultrasound than by computed tomographic scanning. Abscesses can be imaged and aspirated, and hematomas are easily imaged. A variety of vascular lesions including aneurysms and arteriovenous malformations can be localized and characterized. Structural abnormalities such as hydrocephalus and Arnold-Chiari malformation can be well delineated . L'emploi de l'échographie temps réel au cours des interventions neurochirurgicales cérébrales est décrit. Cet examen s'est montré extrêmement utile pour localiser un large éventail de lésions cérébrales superficielles ou profondes ainsi que pur pratiquer une biopsie aspiration de lésions spécifiques. La localisation précise des lésions grâce à l'image échographique diminue la durée de l'intervention et augmente la sécurité de l'acte opératoire. Toutes les lésions tumorales primitives ou métastatiques du cerveau sont bien mises en évidence; le glioma à son début est mieux détecté par l'échographie que par la tomodensitométrie. Les abcès se manifestent par des images particulières et peuvent être évacués par aspiration; les hématomes se traduisent également par des images bien définies. De nombreuses lésions vasculaires: anévrysmes et malformations artério-veineuses peuvent être décelées et localisées. Des anomalies structurales comme L'hydrocéphalie et la malformation d'Arnold-Chiari peuvent être délimitées. Se describe el uso intraoperatorio de ultrasonido de tiempo real en el curso de procedimientos neuroquirúrgicos intracraneanos. Esta técnica ha probado ser extremadamente útil para la localización de una amplia variedad de lesiones cerebrales profundas y superficiales y para la biopsia o aspiración con aguja de lesiones seleccionadas. La precisión en la localización que provee la ultrasonografía acorta el tiempo operatorio e incrementa la seguridad del paciente.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41278/1/268_2005_Article_BF01655829.pd
