We present a measurement of the tt production cross section in pp collisions at square root s = 1.96 TeV which uses events with an inclusive signature of significant missing transverse energy and jets. This is the first measurement which makes no explicit lepton identification requirements, so that sensitivity to W --> tau nu decays is maintained. Heavy flavor jets from top quark decay are identified with a secondary vertex tagging algorithm. From 311 pb(-1) of data collected by the Collider Detector at Fermilab, we measure a production cross section of 5.8 +/- 1.2(stat)(-0.7)(+0.9)(syst) pb for a top quark mass of 178 GeV/c2, in agreement with previous determinations and standard model predictions.

Objective: To provide evidence that catastrophizing is the primer of the cognitive-behavioural model of fear of movement/(re)injury (FAM).
Design: A cross-sectional analysis of 180 outpatients with chronic non-specific low back pain who completed the Pain Catastrophizing Scale (PCS), the Tampa Scale of Kinesiophobia (TSK), the Roland-Morris Disability Questionnaire (RMDQ), the Hospital Anxiety and Depression Scale - Depression (HADS-D), and a pain intensity numerical rating scale (NRS). The intercorrelations of the outcome measures were estimated using Pearson's correlation coefficient (r), and regression analyses were used to examine their predictive values by following the left side of the FAM clockwise from the PCS (p = 0.

Purpose: This study investigates how Mandarin-English bilingual students in Canada produce Mandarin tones and how this is influenced by factors such as tone complexity, cross-linguistic influences, and speech input.
Method: Participants were 82 students enrolled in a Chinese bilingual program in Western Canada. Students were recruited from Grades 1, 3, and 5 and divided into two groups based on their home language backgrounds: The heritage language group had early and strong input in Mandarin, and the second language (L2) group received mostly English input at home.

Rabies is a zoonotic infectious disease of global distribution that impacts human and animal health. In rural Latin America, rabies negatively impacts food security and the economy due to losses in livestock production. The common vampire bat, Desmodus rotundus, is the main reservoir and transmitter of rabies virus (RABV) to domestic animals in Latin America.

Objective: To investigate the association of noncigarette tobacco products with cardiovascular health outcomes.
Design, Setting, And Participants: This cohort study was conducted within the Cross Cohort Collaboration Tobacco Working Group by harmonizing tobacco-related data and conducting a pooled analysis from 15 US-based prospective cohorts with data on the use of at least 1 noncigarette tobacco product ranging between 1948 and 2015.

Background And Objectives: Timely access to specialist care is crucial in expeditious diagnosis and treatment. Our study aimed to assess the time patients wait from being referred by a physician to seeing a neurologist using Medicare data. Specifically, we evaluated differences in access related to sex, race/ethnicity, geography, and availability of neurologists.
