The mass of the W boson, a mediator weak force between elementary particles, is tightly constrained by symmetries standard model particle physics. Higgs boson was last missing component model. After observation measurement provides stringent test We measure mass, MW, using data corresponding to 8.8 inverse femtobarns integrated luminosity collected in proton-antiproton collisions at 1.96 tera-electron volt center-of-mass energy with CDF II detector Fermilab Tevatron collider. A sample...
Endometriosis is an inflammatory chronic pain condition caused by uterine tissue growing outside of the uterus that afflicts at least 11% women (and people assigned female birth) worldwide. This results in a substantial burden to these women, and society large. Although endometriosis was first identified over 160 years ago, knowledge gaps remain, including confirmation disease's etiology. Research funding for limited, with from bodies like National Institutes Health (NIH) constituting only...

Using game balancing techniques can provide the right level of challenge and hence enhance player engagement for sport players with different skill levels. Digital technology support in sports, example, by adjusting players' intensity based on their heart rate. However, there is limited knowledge how to design such its impact user experience. To address this we created two novel enabled digitally augmenting a table tennis table. We adjusted more skilled player's performance inducing styles...
We combine the results of searches for standard model (SM) Higgs boson based on full CDF Run II data set obtained from sqrt[s]=1.96 TeV pp collisions at Fermilab Tevatron corresponding to an integrated luminosity 9.45 fb(-1). The are conducted bosons that produced in association with a W or Z boson, have masses range 90-150 GeV/c(2), and decay into bb pairs. An excess is present inconsistent background prediction level 2.5 deviations (the most significant local 2.7 deviations).

After 15-minute warm-down, the subjects performed 10 vertical...

Playing exertion games with others can be engaging. However, players different physical skill levels competing against each other experience reduced engagement because they are either not challenged enough, or too much. Balancing methods address this; however, there is only limited understanding of balancing in games. In this paper, we identify two distinct dimensional techniques: "internal adjustment" and "external adjustment". We report results from a study where measured player after...

The calf raise test (CRT) assesses plantarflexor strength and endurance, but normative data for children are scarce. Furthermore, contradictions exist on which factors associated with total repetitions, repetitions being the only metric considered. We quantified three of main CRT outcomes (repetitions, work, peak height) in 10-17 years explored their relationship various factors.
