We present a calculation of the single top quark cross section for proton-antiproton interactions with √ s = 1.8 TeV at the Fermilab Tevatron collider. We examine the effects of top mass, parton distribution functions, QCD scale, and collision energy, on each of the component production mechanisms, and study the kinematic distributions for standard model electroweak production. At the upgraded ...

Previous studies of the QED systematic uncertainties on the LEP measurement of the W-boson mass, MW, have used idealized event selections and fitting procedures. In this paper, the Monte Carlo tandem of KoralW and YFSWW is used to investigate how the full experimental MW extraction procedure affects these estimates. It is found that the kinematic fitting used in the experimental determination o...

BACKGROUND Alzheimer's disease (AD) is the most common neurodegenerative dementia of old age, and the leading chronic disease contributor to disability and dependence among older people worldwide. Clinically, AD is characterized by a progressive cognitive decline that interferes with the ability to perform the activities of daily living. Handwriting and drawing are complex human activities that...

The kinematics of a robot with many degrees of freedom is a very complex function. Learning this function for a large workspace with a good precision requires a huge number of training samples, i.e., robot movements. In this paper, we introduce the Kinematic Bézier Map (KB-Map), a parameterizable model without the generality of other systems but whose structure readily incorporates some of the ...

I discuss the kinematic fitting program KWFIT and some general lessons learned in applying kinematic fitting to particle physics data. Though originally written for CLEO use, KWFIT is a general standalone program. KWFIT encodes standard constraints involving vertexing, mass, energy, 4-momentum and back-to-back tracks. A powerful capability is its ability to build “virtual particles” from a set ...

The most precise top quark mass measurements use kinematic reconstruction methods, determining the top mass parameter of a Monte Carlo event generator m_{t}^{MC}. Because of hadronization and parton-shower dynamics, relating m_{t}^{MC} to a field theory mass is difficult. We present a calibration procedure to determine this relation using hadron level QCD predictions for observables with kinema...

Although graphomotor differences and variability of performance have been observed in children with attention deficit hyperactivity disorder (ADHD), no study has investigated whether this variability manifests in the kinematic graphomotor domain in adults with ADHD. Fourteen ADHD and 20 control participants wrote a novel grapheme and common word on a digitizing tablet 30 times each, with ADHD p...

conclusions zebris movement analysis system is a highly reliable instrument for the measurement of gait parameters at different speeds in healthy athletes and those after acl reconstruction surgery. this implies its use in the assessment and treatment process of gait deficits in such a clinically important population. background reconstruction surgery is one of the treatment methods after an an...

time–area method is one of the most widely applied techniques of watershed routing, and can be potentially used as a distributed model. in this paper, a fundamental flaw in the arrangement of subareas in the original time-area histogram is identified for one-dimensional flow. this is conducted on the basis of comparing time-area hydrograph with that of the kinematic wave theorem. accordingly, a...

We study the phenomenology of a supersymmetric bulk in the scenario of large extra dimensions. The virtual exchange of gravitino KK states in selectron pair production in polarized e+e− collisions is examined. The leading order operator for this exchange is dimension six, in contrast to that of graviton KK exchange which induces a dimension eight operator at lowest order. Some kinematic distrib...
