“…These findings suggest that there is a consistent pattern of disparities among the different ethnic groups that have been lagging, suggesting that ethnicity could have an essential role in program effectiveness. These findings are consistent with previous studies showing that ethnicity influenced the utilization of maternal health services [47][48][49]. Specifically for the DRC, ethnicity plays a vital role in the acquisition, maintenance, and distribution of wealth [50] -which may influence the utilization of the MHCS.…”

This study assessed health inequality trends and the degree of maternal healthcare services utilization in the DRC, using two consecutive Demographic and Health Surveys, 2007 and 2013-2014. First, we assessed the changes in the magnitude of inequality in the utilization of MHCS using logistics and regressions. Second, we analyzed the distribution of inequality in each MHCS utilization variable using the Gini coefficient and the Lorenz curve. Third, we used the Wagstaff two groups concentration indices comparison method to assess health inequality trends. Finally, we fitted the concentration curves to estimate the inequality in the utilization of MHCS to the economic condition of women. Women were less likely to have their first ANC visit within the first trimester, less likely to receive checkups during ANC visits, and less likely to attend more ANC visits when living in eastern DRC compared to western DRC. Women in rural areas were less likely to have their last birth by C-section, and less likely to receive PNC than women in urban areas. Women with middle, richer, and richest wealth indexes were more likely to complete more ANC visits, more likely to deliver by C-section, most likely to receive PNC, and more likely to receive ANC than those with lower wealth indexes. Over time, inequality in the utilization of MHCS decreased for ANC and PNC but increased for the delivery by C-sections. These findings suggest that innovative strategies are still needed to improve the utilization of MHC services among poorer, rural, and underserved women in post-conflict DRC.

“…HYDJET++ model provides reasonable description of anisotropic flow in heavy-ion (small, intermediate, and large) collision systems at both RHIC and LHC energies [9][10][11]. The results show proper qualitative as well as quantitative explanation for the flow in spherical and deformed collision systems.…”

“…In recent decades, Relativistic Heavy Ion Collider (RHIC) at the BNL and Large Hadron Collider (LHC) at the CERN have conducted collider experiments, developing an understanding that the deformation of the colliding nuclei strongly affect the QGP observables studied in (ultra-) relativistic heavy-ion collisions [9][10][11]. One of the main motivations in this context has been elliptic flow v 2 [12].…”

“…For instance, significant enhancement was observed in v 2 {2} in deformed central 129 Xe-129 Xe collisions compared to that in case of spherical 129 Xe nucleus. 129 Xe nucleus is proposed to have a small quadrupole deformation, and the enhancement in flow can be seen in the articles [10,[32][33][34][35]. In another study, 238 U-238 U collisions with the nuclei having a substantial quadrupole deformation, also were observed to have an increase in the elliptic flow in ultra-central events [30,[36][37][38].…”

In the hydrodynamical description of heavy-ion collisions, the elliptic flow $${\textrm{v}}_{2}$$ v 2 and triangular flow $${\textrm{v}}_{3}$$ v 3 are sensitive to the quadrupole deformation $${\beta _{2}}$$ β 2 of the colliding nuclei. We produce $${\textrm{v}}_{2}$$ v 2 and $${\textrm{v}}_{3}$$ v 3 ratios qualitatively and quantitatively in most-central Xe–Xe collisions at 5.44 TeV. By employing HYDJET++ model, we study the sensitivity of anisotropic flow coefficients and mean transverse momentum to the quadrupole deformation and system-size in isotopic Xe–Xe collisions. Flow observables strongly depend on the strength of nucleon–nucleon scattering occurring in even-A and odd-A nuclei. Flow for odd-A nuclei is suppressed in comparison to flow in even-A collisions. There exists a linear inter-dependence between $${\textrm{p}}_{\textrm{T}}$$ p T integrated anisotropic flow and nuclear deformation. Mean transverse momentum signifies the fireball temperature in body–body and tip–tip collisions. There exists a negative linear correlation of $$\langle {\textrm{p}}_{\textrm{T}}\rangle $$ ⟨ p T ⟩ with collision system-size and a positive correlation with nuclear deformation. Flow measurements in high-energy, heavy-ion collisions using isotopic collision systems, offer a new precision tool to study nuclear structure physics. Observation of nuclear structure properties like nuclear deformation in a heavy-ion collision such as this would be very interesting.

“…ROS affects the physiological, biochemical, and metabolic processes of cells by causing oxidative stress (Yannarelli et al, 2006). Cyanobacteria have a great ability to adapt to harsh environmental conditions because they have evolved antioxidant systems that mitigate the ROS-induced negative effects (Pandey et al, 2022). Among them, the ASA-GSH cycle is one of the central and most e cient antioxidant systems for the removal of ROS and the maintenance of cellular redox balance.…”

Background Cyanobacteria capable of photosynthesis and nitrogen fixation are considered to be the most promising primary producers of biological life-support systems for Mars exploration, but there is limited information about their survival and growth in space flight or Mars-like environments. Results During the HH-21-5 Balloon-Borne Astrobiology Platform flight mission of the Chinese Academy of Sciences, Nostoc sp. cells were exposed to the Mars-like environment in the stratosphere (35 km altitude) for 2 h in the Temperature-Controlled Biological Samples Exposure Payload. The results showed that the survival rate was high, although analyses did reveal some damage to the cellular metabolic activity and morphology of the experimental samples. Transcriptome analyses revealed that Nostoc sp. activated a set of defense mechanisms under Mars-like radiation levels, which included DNA repair, protein repair of the photosynthetic system, and antioxidant enzymes. Conclusions Results suggest that Nostoc sp. has the potential to survive and grow in Mars-like conditions and that it may be a suitable primary producer in future attempts to colonize Mars using cyanobacteria-based biological life-support systems with groundwater available.
