Assessment of endotracheal tube intubation. Review of existing scales

Due to the complications associated with endotracheal intubation, contraindications should be assessed prior to initiating the procedure when possible. Several scales have been created to assess the ease of intubation. These intubation scales use numerous scoring systems combined with subjective assessments to provide a quantifiable suggestion for the patients difficulty of tracheal intubation. While there is no formal definition of what comprises a difficult intubation, some parameters include effort, number of attempts and complications. Some of the most common scales to assess this difficulty include the Mallampati score, the Cormack Lehane scale, the intubation difficulty scale, the level of difficulty of intubation, as well as the simplified airway risk index. There have been several other proposed methods as well that are less frequently used contributing to even less cohesion in the evaluation of airways

Modifications to the Properties of the Higgs Boson

We explore the impact of new SU(3)XSU(2)XU(1) invariant interactions characterized by a scale of order a TeV on Higgs boson properties. The Higgs production rate and branching ratios can be very different from their standard model values. We also discuss the possibility that these new interactions contribute to acceptable unification of the gauge couplings.Comment: Minor typos fixed. 8 pages, 5 figure

Reductions in prefrontal activation predict off-topic utterances during speech production

The ability to speak coherently is essential for effective communication, but little is known about the neural systems that support coherence. Here, the authors show that activity in two prefrontal cortex regions, BA10 and BA45, predicts the level of coherence in the speech of healthy older adults

Higgs boson phenomenology in tau(+)tau(-) final states at the LHC

We perform a detailed parton level study on the feasibility of the detection of a Higgs boson in the gluon fusion process $pp (gg+gq) \to h + jet \to \tau^+ \tau^- + jet$ at the Large Hadron Collider (LHC). The obtained results are applied to a few chosen Beyond the Standard Model (BSM) scenarios where the branching ratio of a Higgs boson decaying into a $\tau^+ \tau^-$ pair is enhanced as compared to the Standard Model (SM) case. We present the parameter space of the BSM scenarios that can be observed at the LHC and conclude that some regions of the parameter space can be probed with just a few $fb^{-1}$ of integrated luminosity. Noticeably, our results are presented in a form which potentially allows their application to any generic model giving rise to a $pp (gg+gq) \to h + jet \to \tau^+ \tau^- + jet$ signature.Comment: 20 pages, 13 figure
