Abstract

We study the optical and near-infrared luminosities and detectability of radioactively powered electromagnetic transients ('macronovae') occuring in the aftermath of binary neutron star and neutron star black hole mergers. We explore the transients that result from the dynamic ejecta and those from different types of wind outflows. Based on full nuclear network simulations we calculate the resulting light curves in different wavelength bands. We scrutinize the robustness of the results by comparing a) two different nuclear reaction networks and b) two macronova models. We explore in particular how sensitive the results are to the production of alpha-decaying trans-lead nuclei. We compare two frequently used mass models: the Finite-Range Droplet Model (FRDM) and the nuclear mass model of Duflo and Zuker (DZ31). We find that the abundance of alpha-decaying trans-lead nuclei has a significant impact on the observability of the resulting macronovae. For example, the DZ31 model yields considerably larger abundances resulting in larger heating rates and thermalization efficiencies and therefore predicts substantially brighter macronova transients. We find that the dynamic ejecta from NSNS models can reach peak K-band magnitudes in excess of -15 while those from NSBH cases can reach beyond -16. Similar values can be reached by some of our wind models. Several of our models (both wind and dynamic ejecta) yield properties that are similar to the transient that was observed in the aftermath of the short GRB 130603B. We further explore the expected macronova detection frequencies for current and future instruments such as VISTA, ZTF and LSST., Comment: 18 pages, 15 figures

Abstract

With the R$^{3}$B-LAND setup at GSI we have measured exclusive relative-energy spectra of the Coulomb dissociation of $^{18}$C at a projectile energy around 425~AMeV on a lead target, which are needed to determine the radiative neutron-capture cross sections of $^{17}$C into the ground state of $^{18}$C. Those data have been used to constrain theoretical calculations for transitions populating excited states in $^{18}$C. This allowed to derive the astrophysical cross section $\sigma^{*}_{\mathrm{n}\gamma}$ accounting for the thermal population of $^{17}$C target states in astrophysical scenarios. The experimentally verified capture rate is significantly lower than those of previously obtained Hauser-Feshbach estimations at temperatures $T_{9}\leq{}1$~GK. Network simulations with updated neutron-capture rates and hydrodynamics according to the neutrino-driven wind model as well as the neutron-star merger scenario reveal no pronounced influence of neutron capture of $^{17}$C on the production of second- and third-peak elements in contrast to earlier sensitivity studies.

Abstract

A $^{238}$U projectile beam was used to create cadmium isotopes via abrasion-fission at 410 MeV/u in a beryllium target at the entrance of the in-flight separator FRS at GSI. The fission fragments were separated with the FRS and injected into the isochronous storage ring ESR for mass measurements. The Isochronous Mass Spectrometry (IMS) was performed under two different experimental conditions, with and without B$\rho$-tagging at the dispersive central focal plane of the FRS. In the experiment with B$\rho$-tagging the magnetic rigidity of the injected fragments was determined by an accuracy of $2\times 10^{-4}$. A new method of data analysis, using a correlation matrix for the combined data set from both experiments, has provided mass values for 25 different isotopes for the first time. The high selectivity and sensitivity of the experiment and analysis has given access even to rare isotopes detected with a few atoms per week. In this letter we present for the $^{129,130,131}$Cd isotopes mass values directly measured for the first time. The Cd results clearly show a very pronounced shell effect at $N=82$ which is in agreement with the conclusion from $\gamma$-ray spectroscopy of $^{130}$Cd and confirms the assumptions of modern shell-model calculations., Comment: 7 pages, 5 figures, 3 tables

Abstract

We present a study of nucleosynthesis for conditions of high Ye outflows from Neutron Star Mergers (BNSs). We investigate the effect of new beta–decay rates measurements and uncertainties in nuclear masses of the newly measured 84,85Ga to the r–process nucleosynthesis calculations. The impact of these quantities to the production of the elements of the r–process abundance pattern for A

Abstract

To analyze the positivity rate and titer of antinuclear antibody (ANA), as well as nuclear pattern and target antigen of ANA in healthy pregnant women during early pregnancy in Qingdao area. A prospective cohort study design was used to include a total of 9 528 healthy pregnant women registered at the Women and Children's Hospital Affiliated to Qingdao University from March 2023 to June 2024.Indirect immunofluorescence assay (IIF) was used to detect ANA, its titer and cell staining pattern. Fifteen specific antibodies were tested using the magnetic bar code immunofluorescent luminescence method. Logistic regression model was used to analyze the risk factors of pregnancy with autoimmune disease(AID). The results showed that among 9 528 pregnant women in early pregnancy, 1 346 cases (14.1%) were positive of ANA, including 1 011 cases with a titer of 1∶100 (10.6%), 236 cases (2.5%) with a titer of 1∶320, and 99 cases (1.0%) were detected at a titer >1∶320. Among the 1 346 ANA-positive pregnant women, nuclear granular type accounted for the highest proportion (483 cases, 35.9%), followed by speckled type (347 cases, 25.8%) and cytoplasmic type (176 cases, 13.1%).Then, pregnant women with ANA titers ≥1∶100 were detected 15 specific antibodies.Anti-SSA was tested in 121 cases accounted for the majority, followed by 110 cases with anti-Ro-52, 56 cases with anti-SSB, 51 cases with anti-mitochondrial M2 subtype antibodies and 37 cases with anti-centromere B. In conclusion,in healthy pregnant women in Qingdao area, ANA positivity rate was 14.1%, and the titer of ANA was mainly at 1∶100.The predominant nuclear patterns were nuclear granular and speckled types.The specific autoantibodies were mainly anti-SSA antibodies and anti-Ro-52 antibodies.The detection of ANA and specific autoantibodies is of great significance for early prediction, diagnosis, and intervention of autoimmune diseases during pregnancy.

Abstract

Penetrating injuries of the paranasal sinuses due to foreign bodies are rare, especially as a result of a traffic accident. Here we report a patient with a ballpoint pen lodged in his left eye following a traffic accident. The pen extended from the medial aspect of the left orbit, through the left ethmoid sinus and the nasal septum, to the right sphenoid sinus. We removed the pen uneventfully using endoscopic sinus surgery. There are no similar reports in the English literature and we therefore present this case because of its rarity.
