Search for a heavy particle decaying to a top quark and a light quark in pp ¯ collisions at √s=1.96 TeV.

We present a search for a new heavy particle X produced in association with a top quark, pp[over ¯]→t(X→t[over ¯]q) or pp[over ¯]→t[over ¯](X[over ¯]→tq[over ¯]), where q stands for up quarks and down quarks. Such a particle may explain the recent anomalous measurements of top-quark forward-backward asymmetry. If the light-flavor quark (q) is reconstructed as a jet (j), this gives a t[over ¯]+j or t+j resonance in tt[over ¯]+jet events, a previously unexplored experimental signature.

The influence of stress, depression, and anxiety on PSA screening rates in a nationally representative sample.

Background: Prostate-specific antigen (PSA) testing for prostate cancer is controversial, with concerning rates of both overscreening and underscreening. The reasons for the observed rates of screening are unknown, and few studies have examined the relationship of psychological health to PSA screening rates. Understanding this relationship can help guide interventions to improve informed decision-making for screening.

A study on community perceptions of common cancers, determinants of community behaviour and program implementation in New Delhi, India.

Assessment of perceptions of the community, the determinants and development of their behavior regarding common malignancies, helps in establishing evidence-based activities for prevention and early diagnosis of cancer. However information on this important aspect is lacking in our country. Qualitative methods were here used to obtain information through in depth interviews and Focus Group Discussions (FGDs) with all categories of identified stakeholders.

In addition to requiring exactly one lepton, large missing transverse momentum, and at least six jets, the invariant mass of nearby jet pairs is used to identify high transverse momentum W bosons. In data corresponding to an integrated luminosity of 1.
