Search for the X(5568) State Decaying into B_{s}^{0}π^{±} in Proton-Proton Collisions at sqrts=8  TeV.

A search for resonancelike structures in the B_{s}^{0}π^{±} invariant mass spectrum is performed using proton-proton collision data collected by the CMS experiment at the LHC at sqrt[s]=8  TeV, corresponding to an integrated luminosity of 19.7  fb^{-1}. The B_{s}^{0} mesons are reconstructed in the decay chain B_{s}^{0}→J/ψϕ, with J/ψ→μ^{+}μ^{-} and ϕ→K^{+}K^{-}. The B_{s}^{0}π^{±} invariant mass distribution shows no statistically significant peaks for different selection requiremen...

Collision tumor of glioblastoma and meningioma: case report and literature review.

Intracranial primary collision tumors of different histologic types are rare. Until now, it is still unclear about the occurrence of collision tumors.

Nonadiabatic Breaking of Topological Pumping.

We study Thouless pumping out of the adiabatic limit. Our findings show that despite its topological nature, this phenomenon is not generically robust to nonadiabatic effects. Indeed, we find that the Floquet diagonal ensemble value of the pumped charge shows a deviation from the topologically quantized limit which is quadratic in the driving frequency for a sudden switch on of the driving. This is reflected also in the charge pumped in a single period, which shows a nonanalytic behavior on top of an overal...

A qualitative exploration of driving stress and driving discourtesy.

Driving courtesy, and conversely driving discourtesy, recently has been of great interest in the public domain. In addition, there has been increasing recognition of the negative impact of stress upon the individual's health and wellbeing, with a plethora of interventions aimed at minimising stress more generally. The research literature regarding driving dis/courtesy, in comparison, is scant, with a handful of studies examining the dis/courteous driving behaviour of road users, and the relationship between...

Difference between car-to-cyclist crash and near crash in a perpendicular crash configuration based on driving recorder analysis.

Analyzing a crash using driving recorder data makes it possible to objectively examine factors contributing to the occurrence of the crash. In this study, car-to-cyclist crashes and near crashes recorded on cars equipped with advanced driving recorders were compared with each other in order to examine the factors that differentiate near crashes from crashes, as well as identify the causes of the crashes. Focusing on cases where the car and cyclist approached each other perpendicularly, the differences in th...

Analysis of vehicle collision accidents based on qualitative mechanics.

In this paper, a method for vehicle collision analysis based on qualitative mechanics is presented. In collisions where accurate quantitative information is difficult to gather, this analytic method can act as a useful complement. Based on qualitative dynamic theories, reasonings of various factors including qualitative vector, collision behavior, translational and rotational motion are suggested. Using the law of momentum conservation within the frame of rigid-body dynamics, vehicle collision analyses base...

Internal radiation dose estimation using multiple D-shuttle dosimeters for positron emission tomography (PET): a validation study using NEMA body phantom.

Internal radiation dosimetry plays an important role in ensuring the safe use of positron emission tomography (PET) technology and is a legal requirement in most countries. We propose a new technique to estimate the internal radiation dose in PET studies by means of multiple D-shuttle dosimeters attached on the body surface of the patient.

Bird-building collision risk: An assessment of the collision risk of birds with buildings by phylogeny and behavior using two citizen-science datasets.

Bird collisions with buildings are the second largest anthropogenic source of direct mortality for birds (365-988 million birds killed annually in the United States). Recent research suggests that this mortality occurs disproportionately across species. However, previous work had relied on regional and annual measures of relative species abundance. Our research identifies which species experience higher or lower collision rates than expected from local abundances using two sets of citizen science data: Minn...

Collision cross section (CCS) measurement by ion cyclotron resonance mass spectrometry with short-time Fourier transform.

Collision cross section (CCS) is an important shape parameter which is often used in molecular structure investigation. In Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), CCS affects ion signal damping shape due to the effect of ion-neutral collision. It is potential to obtain ion CCS value from FT-ICR MS with the help of proper ion-collision model.

Health and Safety Education in Auto Body Collision and Machine Tool Technology Programs in Vocational Colleges: Challenges and Opportunities.

Collision repair, machining, and metal manufacturing are industries with a large percentage of small businesses whose owners face unique challenges implementing health and safety regulatory requirements. Previous research found that 72% of collision repair technicians and 47% of machinists attended some classes or graduated from vocational colleges. Although health and safety is a mandatory part of the curricula for post-secondary vocational education, little is known about what, how, and when health and sa...

Effects of Driving Skill Training on Safe Driving in Older Adults with Mild Cognitive Impairment.

Driving cessation is strongly associated with adverse health outcomes in the older adults. Although there were numerous documentations of driving rehabilitation in disabled adults, the effects of interventions on safe driving were not clear in older adults with cognitive impairment who had low driving skills.

Driving under the influence of drugs: prevalence in road traffic accidents in Italy and considerations on "per se" limits legislation.

To present the prevalence and concentrations of drugs in blood samples of drivers involved in road traffic accidents (RTA) and to discuss the effects of adopting different concentration cut-off values proposed or applied in other European countries on the number of driving under the influence of drugs (DUID) offences.

How does intersection field of view influence driving safety in an emergent situation?

Restricted intersection field of view (IFOV) can influence drivers' hazard detection abilities and driving safety in an emergent traffic event. However, no field studies or crash-data analyses have been conducted to prove the adequateness of the current intersection sight-distance design standards, which are adopted to ensure that the approaching-intersection drivers have a sufficient field of view to detect traffic hazards and travel safely at intersections. In this study, we conducted a driving simulator ...

Simulated car driving and its association with cognitive abilities in patients with schizophrenia.

Patients with schizophrenia commonly suffer from impairments in various aspects of cognition. These deficits were shown to have detrimental effects on daily life functioning and might also impair car driving. This study is the first to examine driving behaviour of patients with schizophrenia using an advanced driving simulator, and to explore the role of cognitive abilities of people with schizophrenia for driving.

Mechanistic alternatives for peptide bond formation on the ribosome.

The peptidyl transfer reaction on the large ribosomal subunit depends on the protonation state of the amine nucleophile and exhibits a large kinetic solvent isotope effect (KSIE ∼8). In contrast, the related peptidyl-tRNA hydrolysis reaction involved in termination shows a KSIE of ∼4 and a pH-rate profile indicative of base catalysis. It is, however, unclear why these reactions should proceed with different mechanisms, as the experimental data suggests. One explanation is that two competing mechanisms m...

Thirteen physically active men (age: 21.2 ± 2.9 years, height: 175.6 ± 5.6 cm, body-mass: 72.4 ± 8.6 kg) performed a 5-m shuttle run test (6 × 30-s + 35-s of recovery in-between) during five experimental periods: fifteen days before Ramadan (BR), the first ten days of Ramadan (FR), the last ten ...

Vehicle ownership and other predictors of teenagers risky driving behavior: Evidence from a naturalistic driving study.

Risky driving behavior may contribute to the high crash risk among teenage drivers. The current naturalistic driving study assessed predictors for teenagers' kinematic risky driving (KRD) behavior and the interdependencies between them.

Driving style indicator using UDRIVE NDS data.

In order to analyze specific events while driving (such as a safety critical event [SCE] or secondary task), we were interested in studying whether driving behavior was unusual around the event. An indicator characterizing driving style (driving style indicator [DSI]) was estimated for each driver by using naturalistic data. The analysis of the gap in driving style could be calculated for a specific trip or even a time window and could help characterize events: a more risky situation when DSI was above aver...
