This study aimed to compare the effect of pneumatised and non-pneumatised mastoid on the success of tympanoplasty in terms of rate of graft uptake and air-bone gap improvement. A comprehensive electronic search of PubMed Medline, Scopus, Web of Science and Cochrane Library was conducted in August 2020 for articles from 1990 to 2020. Selected studies were published in the English language, were conducted on human patients, were concerned with evaluating pre-operative mastoid pneumatisation on tympanoplasty success, were not laboratory studies and were not opinion studies. Five studies were included with 178 patients in the pneumatised group and 97 patients were included in the non-pneumatised group. Comparison between both groups was performed in terms of graft uptake rate and air-bone gap improvement. Although the pneumatised group showed better graft uptake rate than the non-pneumatised group, there was no statistically significant difference between the two groups in the success rate of tympanoplasty. Pneumatisation of the mastoid does not significantly affect the success rate of tympanoplasty.

We employ the SMASH transport model to provide event-by-event initial conditions for the energy-momentum tensor and conserved charge currents in hydrodynamic simulations of relativistic heavy-ion collisions. We study the fluctuations and dynamical evolution of three conserved charge currents (net baryon, net electric charges, and net strangeness) with a 4D lattice-QCD-based equation of state, NEOS-4D, in the hydrodynamic phase. Out-of-equilibrium corrections at the particlization are generalized to finite densities to ensure the conservation of energy, momentum, and the three types of charges. These theoretical developments are integrated within the X-SCAPE code as a unified framework for studying the nuclear matter properties in the Beam Energy Scan program.

The pseudorapidity distribution of charged hadrons produced in Au+Au collisions at a center-of-mass energy of $\\sqrt{{\\textrm{s}}_{\\textrm{NN}}}$ = 200 GeV is measured using data collected by the sPHENIX detector. Charged hadron yields are extracted by counting cluster pairs in the inner and outer layers of the Intermediate Silicon Tracker, with corrections applied for detector acceptance, reconstruction efficiency, combinatorial pairs, and contributions from secondary decays. The measured distributions cover |η| < 1.1 across various centralities, and the average pseudorapidity density of charged hadrons at mid-rapidity is compared to predictions from Monte Carlo heavy-ion event generators. This result, featuring full azimuthal coverage at mid-rapidity, is consistent with previous experimental measurements at the Relativistic Heavy Ion Collider, thereby supporting the broader sPHENIX physics program.

A comprehensive Bayesian analysis of the 3D dynamics of high-energy nuclear collisions is presented. We perform a systematic model-to-data comparison using simulations of large and small collision systems, and a broad range of measurements from the PHENIX, STAR, PHOBOS, and BRAHMS collaborations spanning nearly two decades of RHIC operations. In particular, we perform fully 3D multi-stage simulations including rapidity-dependent energy deposition with global energy conservation using the 3D Glauber model, along with relativistic viscous hydrodynamics with MUSIC. We calibrate the model on rapidity- and \\(p_T\\)-differential observables and analyze the respective constraints on initial state and transport properties they provide. We emphasize the additional constraints provided by rapidity-dependent measurements, the differences in large and small system calibrations, and the tension exhibited by particular observables. We use our calibrated model to make predictions of observables in p-Au and \\(^3\\)He-Au collisions. Furthermore, we facilitate direct comparison of experimental measurements by highlighting the dependence of flow measurements on the rapidity of the regions of interest and reference, as well as the importance of the centrality selection. In particular, we examine the apparent differences between the STAR and PHENIX \\(v_2\\) and \\(v_3\\) measurements in small systems.

The pseudorapidity distribution of charged hadrons produced in Au+Au collisions at a center-of-mass energy of \\(\\sqrt{s_\\mathrm{NN}} = 200\\) GeV is measured using data collected by the sPHENIX detector. Charged hadron yields are extracted by counting cluster pairs in the inner and outer layers of the Intermediate Silicon Tracker, with corrections applied for detector acceptance, reconstruction efficiency, combinatorial pairs, and contributions from secondary decays. The measured distributions cover \\(|\\eta| < 1.1\\) across various centralities, and the average pseudorapidity density of charged hadrons at mid-rapidity is compared to predictions from Monte Carlo heavy-ion event generators. This result, featuring full azimuthal coverage at mid-rapidity, is consistent with previous experimental measurements at the Relativistic Heavy Ion Collider, thereby supporting the broader sPHENIX physics program.

This paper reports measurements of the transverse energy per unit pseudorapidity (\\(dE_{T}/d\\eta\\)) produced in Au+Au collisions at \\(\\sqrt{s_{NN}} = 200\\) GeV, performed with the sPHENIX detector at the Relativistic Heavy Ion Collider (RHIC). The results cover the pseudorapidity range \\(\\left|\\eta\\right| < 1.1\\) and constitute the first such measurement performed using a hadronic calorimeter at RHIC. Measurements of \\(dE_{T}/d\\eta\\) are presented for a range of centrality intervals and the average \\(dE_{T}/d\\eta\\) as a function of the number of participating nucleons, \\(N_{\\mathrm{part}}\\), is compared to a variety of Monte Carlo heavy-ion event generators. The results are in agreement with previous measurements at RHIC, and feature an improved granularity in \\(\\eta\\) and improved precision in low-\\(N_{\\mathrm{part}}\\) events.
