Two planthopper species of the family Nogodinidae are added to the fauna of Vietnam, both from two localities in Thua Thien-Hue Province: Bach Ma National Park and Phong Dien District. The first species belongs to Goniopsarites Meng, Wang & Wang, 2014, G. mientrunganus Constant & Pham, sp. nov., and the second belongs to Pisacha Distant, 1906, P. yinggensis Meng, Wang & Wang, 2014. Pisacha yinggensis was previously recorded from Hainan Island, China. These new records greatly extend the distribution of both genera, which were known from southern China, Hainan and North Vietnam, to the south, reaching the mid area of Central Vietnam. Sexual dimorphism is reported in P. yinggensis for the first time. Illustrations of habitus and male terminalia of the new species are given as well as distribution maps and photographs of live specimens and their habitat. The family Nogodinidae now comprises nine species in Vietnam, with three of them present in Bach Ma National Park.

The Architecture Analysis and Design Language (AADL) is a SAE Standardfor the modeling of both the hardware and the software of embedded systems. The AADL standard is now mature and is today employed by numerous stakeholders in the domain of critical embedded real-time systems to address a large set of concerns: performances (latency, schedulability), safety, or security, ... The ADEPT workshop aims to present and report on current projects in the field of design, implementation, and verification of critical systems where AADL is a first-citizen technology. This article is a summary of the ADEPT 2022 workshop. [ABSTRACT FROM AUTHOR]

Dynamically ensuring the correctness of the functional behavior of a real-time embedded system is tedious, especially in the autonomous domain. Even though the current real-time task model provides sufficient information to perform basic schedulability tests, it is inadequate to be used in runtime monitoring to assert and guarantee the correctness of a system under hardware/- software malfunctions or malicious cyber attacks. In this article, we present a runtime monitoring approach based on a fine-grained model of real-time tasks. [ABSTRACT FROM AUTHOR]

This study presents a facial co-precipitation method to enrich low-valent manganese sites for iron-doped cryptomelane. Fourier-transform infrared spectroscopy exhibits a noticeable enhancement of both vibrations at 1041 and 1116 cm-1 ascribed to Mn3+-OH bond over as-prepared materials. X-ray diffraction, scanning electron microscopy, Raman spectroscopy, the temperature-programmed desorption of oxygen and inductively coupled plasma-mass spectrometry results all verify the increase in oxygen vacancies on iron-doped cryptomelane. The vital role of Mn3+-OH sites for adsorptive removal of acid blue 62 (AB62) was experimentally evident when adsorption capacity (Qe, mgAB62/gadsorbent) increased from 54 ± 1.3 mg/g (for non-doped cryptomelane) to 161 ± 6.7 mg/g (for Fe-0.15) at initial pH 5.7. The decrease of Qe from 313 mg/g (for initial pH 3.70) to 67 mg/g (for initial pH 9.95) over Fe-0.15 suggests protonation in acid media and deprotonation in basic media, reflecting efficient Mn3+-OH sites for reinforced interaction with sulfonate groups. The disappearance of sharp bands at 1041 and 1116 cm-1 after adsorption and the replenishment of a broad band at ∼1250 cm-1 over Fe-0.15 demonstrate the displacement of sulfonate groups by -OH species (from Mn3+-OH sites). Moreover, the deterioration of two stretching modes for O=S=O at 1187 and 1230 cm-1 after adsorption reveals the formation of a monodentate or bidentate complex. Kinetic studies confirm the compatibility of AB62 chemisorption over Fe-0.15 with the pseudo-second-order kinetic, Elovich, and Langmuir isotherm models. The current findings first support evidences for the AB62 chemisorption on iron-doped cryptomelane and a Fe-0.15-feasible adsorbent for removal of sulfonated anthraquinone dye.
