Introduction: Neonatal mortality remains a major public health concern. According to the World Health Organisation (WHO), the number of newborns dying each year has fallen from 5 million in 1990 to 2.4 million in 2019. The aim of our study was to describe the main morbid conditions and their lethality in newborns admitted to the paediatric ward of the CSREF in Commune V. Methodology: We conducted a 12-month prospective descriptive and analytical study from August 2020 to July 2021. Results: During the 12 months of the study, out of 2654 neonates admitted to hospital, 216 met our inclusion criteria, i.e. 8%. Newborns admitted in the first few hours of life represented 99.54% of cases. Full-term newborns accounted for 65.74% of the total. Forty-eight percent of newborns had hypothermia on admission. The most common diagnosis was asphyxia in 55.56% of cases, followed by neonatal infection in 27.78% and prematurity in 10.65%. Death was recorded in 22.2% of cases. Asphyxia was the main cause of neonatal death, followed by prematurity in our context. Conclusion: Improving the prognosis of newborn babies will require a thorough understanding of neonatal pathologies and the implementation of a pre- and perinatal prevention policy.

近年来,非厄米系统,特别是宇称-时间(PT)对称系统引起的特殊物理现象吸引了许多科研人员。具有光谱退化性质的异常点(EP)和特征值分别为无限大及零的相干完美吸收-激光(CPAL)点是其中最为热门的研究课题。迄今为止,对于作为PT对称系统的破缺相和确定相边界的EP讨论已经有了非常多的成果。然而,针对CPAL点的理论分析和实验验证,相对于EP来说,仍有不足。与EP不同,CPAL点作为PT对称系统中破缺相中的一个特殊解,可能会表现出更加违反直觉的物理特征,而这些表现可能对研究非厄米物理学有着重要的意义。本文回顾了在不同物理子学科中关于CPAL现象的一些研究,包括光学、电子和电磁学、以及声学。此外,对于CPAL系统未来可能的发展方向及应用给出了一些设想。

Commercial application of lithium-sulfur(Li-S) batteries is hindered by the insulating nature of sulfur and the dissolution of polysulfides. Here, a bioinspired 3D urchin-like N-doped Murray's carbon nanostructure(N-MCN) with interconnected micro-meso-macroporous structure and a polydopamine protection shell has been designed as an effective sulfur host for high-performance Li-S batteries. The advanced 3D hierarchically porous framework with the characteristics of the generalized Murray's law largely improves electrolyte diffusion, facilitates electrons/ions transfer and provides strong chemisorption for active species, leading to the synergistic structural and chemical confinement of polysulfides. As a result,the obtained P@S/N-MCN electrode with high areal sulfur loading demonstrates high capacity at high current densities after long cycles. This work reveals that following the generalized Murray's law is feasible to design high-performance sulfur cathode materials for potentially practical Li-S battery applications.

This paper focuses on the economic development and urban morphology as well as its impact on the transportation system during the urban expansion of Shanghai in the last more than 20 years(1986-2008).Based on data from 3 comprehensive transport surveys of Shanghai since 1986,the changes in residential trip demand,vehicle use,and the spatial distribution of trips were studied to understand the demands on the transportation *** factors contributing to those changes in transportation demand were discussed,by which the conclusions were arrived:1) economic development promotes population growth and stimulates residential trip demand greatly;2) unsynchronized migration of population and job from central district to periphery district of Shanghai make trips and congestion diffuse in the same way;and 3) urban sprawl from a city center encourages the single-occupant vehicle mode,which imposes greater pressure on the roadway *** is concluded that urban development should coordinate with the transportation system planning and expansion.
