To achieve precise photometry, we present a new image-differencing technique that is implemented for the first time on the ROTSE SN photometry pipeline. With this method, we find up to a 20% increase in the detection efficiency and significant reduction in residual rms scatter of the SN lightcurves when compared to the previous pipeline performance. We use the published optical spectra and broadband photometry of well-studied SNe IIP to establish temporal models for ejecta velocity and photospheric temperature evolution for our SNe IIP population. This study yields measurements that are competitive with other methods even when the data are limited to a single epoch during the photospheric phase of SNe IIP. Using the fully reduced ROTSE photometry and optical spectra, we apply these models to the respective photometric epochs for each SN in the ROTSE IIP sample. This facilitates the use of the Expanding Photosphere Method (EPM) to obtain distance estimates to their respective host galaxies. We then perform cosmological parameter fitting using these EPM distances, from which we measure the Hubble constant to be 72.9(-4.3)(+5.7)kms(-1)Mpc(-1) , which is consistent with the standard Lambda CDM model values derived using other independent techniques.

However, the PA signal is prone to changes in bulk composition, leading to relative uncertainties in measurements of up to 10%, due to the complex dependence of the sensitivity of a PA system (S) on the thermal and acoustic properties of the gas sample. A novel calibration and concentration calculation method is proposed to keep the relative accuracy of the PA measurements in the few percentages range even in case of large-scale composition variations. The main novelty of the proposed method is that it tackles the complex dependence of the PA system's sensitivity in a way that while it varies the resonance frequency of the calibration gas, it keeps the heat capacity ratio of calibration gases at a constant value. We prove that it determines the analyte's concentration with relative accuracy of about 1 %, even when the composition of the gas varies drastically. It rigorously compensates for the frequency and heat capacity ratio dependence of S and for the dependence of the half-width of the resonance curve of the PA cell on the thermal and acoustic properties of the gas. Although the reported demonstration measurements are executed in a relatively simple gas mixture, the proposed method has widespread applicability in high-precision monitoring. © 2024 The Authors LA - English DB - MTMT ER - TY - JOUR AU - Farkas, Dávid AU - Szikora, Szilárd AU - Jijumon, A S AU - Polgár, Tamás Ferenc AU - Patai, Roland AU - Szütsné Tóth, Mónika Ágnes AU - Bugyi, Beáta AU - Gajdos, Tamás AU - Bíró, Péter AU - Novák, Tibor AU - Erdélyi, Miklós AU - Mihály, József TI - Peripheral thickening of the sarcomeres and pointed end elongation of the thin filaments are both promoted by SALS and its formin interaction partners JF - PLOS GENETICS J2 - PLOS GENET VL - 20 PY - 2024 IS - 1 PG - 31 SN - 1553-7390 DO - 10.1371/journal.pgen.1011117 UR - https://m2.mtmt.hu/api/publication/34506131 ID - 34506131 N1 - Institute of Genetics, Biological Research Centre, Szeged, Hungary Institute of Biophysics, Biological Research Centre, Szeged, Hungary Doctoral School of Theoretical Medicine, University of Szeged, Szeged, Hungary University of Pécs, Medical School, Department of Biophysics, Pécs, Hungary Department of Optics and Quantum Electronics, University of Szeged, Szeged, Hungary University of Szeged, Department of Genetics, Szeged, Hungary Export Date: 29 January 2024 Correspondence Address: Mihály, J.; Institute of Genetics, Hungary; email: mihaly.jozsef@brc.hu AB - During striated muscle development the first periodically repeated units appear in the premyofibrils, consisting of immature sarcomeres that must undergo a substantial growth both in length and width, to reach their final size. Here we report that, beyond its well established role in sarcomere elongation, the Sarcomere length short (SALS) protein is involved in Z-disc formation and peripheral growth of the sarcomeres. Our protein localization data and loss-of-function studies in the Drosophila indirect flight muscle strongly suggest that radial growth of the sarcomeres is initiated at the Z-disc. As to thin filament elongation, we used a powerful nanoscopy approach to reveal that SALS is subject to a major conformational change during sarcomere development, which might be critical to stop pointed end elongation in the adult muscles. In addition, we demonstrate that the roles of SALS in sarcomere elongation and radial growth are both dependent on formin type of actin assembly factors. Unexpectedly, when SALS is present in excess amounts, it promotes the formation of actin aggregates highly resembling the ones described in nemaline myopathy patients. Collectively, these findings helped to shed light on the complex mechanisms of SALS during the coordinated elongation and thickening of the sarcomeres, and resulted in the discovery of a potential nemaline myopathy model, suitable for the identification of genetic and small molecule inhibitors.
