We report on near-body measurements of temperature and nitric oxide (NO) concentration in the hypersonic flows around a cylindrical test article in the Caltech T5 reflected shock tunnel. Flow measurements were made at 50 kHz using tunable diode laser absorption spectroscopy, deploying six lasers to probe an array of quantum state-specific transitions. Laser beams were positioned both in the freestream and behind the bow shock at specific locations deemed pertinent to computational fluid dynamics comparison and kinetic model evaluation. The fractions of laser beam pathlengths behind the shock in different spatial regions were also discerned, thus providing a measurement of shock location. This study consists of six total experiments (“shots”) across two Mach [Formula: see text] conditions, characterized by total enthalpies of 8 and [Formula: see text] and freestream velocities of 3.5 and [Formula: see text], respectively. Freestream measurements generally concur with prior works in the T5, but with some non-trivial differences. Shock-layer measurements span from 2000 to 6000 K and feature noteworthy and expected variety among different zones within the post-shock region. Thermal equilibrium is generally held throughout the flowfield, but chemical nonequilibrium is commonly observed. NO is the primary spectroscopic target, but measurements of carbon monoxide, carbon dioxide, water, and atomic oxygen provide supplementary insights.
Characteristic Vibrational and Rotational Relaxation Times for Air Species from First-Principles Calculations
Authors: Torres Erik , Schwartzentruber Thomas E. 
Published: August 2024

We present molecular-scale computational rotational-vibrational relaxation studies for [Formula: see text], [Formula: see text], and [Formula: see text]. Characteristic relaxation times for diatom-diatom and diatom-atom interactions are calculated using direct molecular simulation (DMS), with ab initio potential energy surfaces (PESs) as the sole model input. Below approximately 8000 K our [Formula: see text], [Formula: see text], and [Formula: see text] vibrational relaxation times agree well with the Millikan–White (M&W) correlation, but gradually diverge at higher temperatures. Park’s high-temperature correction produces a relatively steeper temperature rise compared to our estimates. DMS further shows that, with increasing temperature, the gap between vibrational and rotational relaxation times shrinks for all species. At [Formula: see text] their magnitudes become comparable and a clear distinction between both energy modes becomes meaningless. For other interactions, our DMS results differ substantially from the M&W correlation, both in magnitude and temperature dependence. Our predicted [Formula: see text] vibrational relaxation times are noticeably shorter due to vibration-vibration transfer. For [Formula: see text] we observe minimal temperature dependence. Our [Formula: see text] and [Formula: see text] predictions follow the M&W temperature trend at values roughly one order of magnitude smaller. For [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] we generate partial data due to currently incomplete PES sets. These first-principles-derived relaxation times are useful for informing relaxation models in gas-kinetic and fluid-dynamics simulations of high-enthalpy flows.
Importance of biomarkers in streptococcal acute tonsillitis & peritonsillar abscess
Authors: Unal Onur , Kumbul Yusuf Cagdas , Akin Vural 
Published: August 2024

Background & objectives
Acute tonsillitis is a disease that can often be cured with medical treatment. However, complications may occur during this disease process. One of these complications is peritonsillar abscess. In recent years, biomarkers have been frequently used in the diagnosis of diseases. The aim of the study was to reveal whether peritonsillar abscess develops after acute tonsillitis, and acute tonsillitis can be differentiated using biomarkers and which biomarker has higher predictive value for this differentiation.

Methods
The control group consisted of individuals who were operated for septoplasty in the otolaryngology clinic, and the acute tonsillitis group consisted of individuals diagnosed with acute tonsillitis in the same clinic. Both groups were statistically compared in terms of mean platelet volume (MPV), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), systemic immune inflammation index (SII), infection discrimination index (IDI), plateletcrit (PCT) and lymphocyte to monocyte ratio (LMR) biomarkers. Statistically, significant biomarker values were compared between the subgroups in the tonsillitis group of those who had only acute tonsillitis and those who had peritonsillar abscess due to acute tonsillitis. Receiver operating characteristics (ROC) curve analysis was performed on biomarkers for their ability to predict the presence of peritonsillar abscess.

Results
When the individuals who had only acute tonsillitis and those who had acute tonsillitis with peritonsillar abscess were compared in terms of biomarkers, there was a statistically significant difference between the mean MPV, SII and PCT (P=0.010, 0.021, 0.023, respectively). ROC analysis was performed to calculate the sensitivity and specificity of MPV, PCT and SII for the diagnosis of acute tonsillitis with peritonsillar abscess (sensitivity-specificity for MPV 51.9–72.7%, for SII 94.2–32.7%, for PCT 71.2–50.9%, respectively).

Interpretation & conclusions
MPV, SII and PCT biomarkers may be useful to help clinicians predict peritonsillar abscess due to acute tonsillitis.

Objectives:
Achieving a ‘good death’ is one of the important goals of palliative care. Providing goal-concordant care and an environment tailored to the patient’s preferences can contribute to a ‘good death’. However, the concordance rate between the preferred and actual places of death among advanced cancer patients in Japan is less explored. This study aimed to identify the concordance between patients’ preferred and actual places of death and the associated factors among patients with advanced cancer in Japan.

Materials and Methods:
Patients with advanced cancer who underwent chemotherapy at Tohoku University Hospital between January 2015 and January 2016 were enrolled and followed up for 5 years. The enrolled patients were asked about their preference for their place of death. The response options were: “Own home,” “General ward” and “Palliative care unit (PCU).” We compared the actual place of death with the patient’s preference through a follow-up review of the medical records.

Results:
A total of 157 patients with advanced cancer were enrolled between January 2015 and January 2016. Of these patients, 22.9% (11/48) died at home according to their preference, 64.0% (16/25) in the general ward and 37.9% (11/29) in the PCU. Only thirty-seven (37.3%) patients died where they wanted, based on the comparison between patients’ preferences and actual places of death.

Conclusion:
The concordance rate between the preferred and actual places of death is not high in Japan. Improving concordance between patients’ preferences and actual places of death has the potential to improve end-of-life care.
