Immunological Diversity Is a Cornerstone of Organismal Defense and Allorecognition across Metazoa
Authors: Buckley Katherine M , Dooley Helen 
Published: January 2022

Abstract
The ongoing arms race between hosts and microbes has fueled the evolution of novel strategies for diversifying the molecules involved in immune responses. Characterization of immune systems from an ever-broadening phylogenetic range of organisms reveals that there are many mechanisms by which this diversity can be generated and maintained. Diversification strategies operate at the level of populations, genomes, genes, and even individual transcripts. Lineage-specific innovations have been cataloged within the immune systems of both invertebrates and vertebrates. Furthermore, somatic diversification of immune receptor genes has now been described in jawless vertebrates and some invertebrate species. In addition to pathogen detection, immunological diversity plays important roles in several distinct allorecognition systems. In this Brief Review, we highlight some of the evolutionary innovations employed by a variety of metazoan species to generate the molecular diversity required to detect a vast array of molecules in the context of both immune response and self/nonself-recognition.
One Size Does Not Fit All: Diversifying Immune Function in the Skin
Authors: Naik Shruti 
Published: January 2022

Abstract
Our body’s most outward facing epithelial barrier, the skin, serves as the frontline defense against myriad environmental assailants. To combat these motley threats, the skin has evolved a sophisticated immunological arsenal. In this article, I provide an overview of the skin’s complex architecture and the distinct microniches in which immune cells reside and function. I review burgeoning literature on the synchronized immune, stromal, epithelial, and neuronal cell responses in healthy and inflamed skin. Next, I delve into the distinct requirement and mechanisms of long-term immune surveillance and tissue adaptation at the cutaneous frontier. Finally, by discussing the contributions of immune cells in maintaining and restoring tissue integrity, I underscore the constellation of noncanonical functions undertaken by the skin immune system. Just as our skin’s immune system benefits from embracing diverse defense strategies, so, too, must we in the immunology research community support disparate perspectives and people from all walks of life.

AbstractFor
$0<\lambda ,p<1$
, the Dirichlet–Morrey space
$\mathcal {D}_p^{\lambda } $
is the space of all analytic function on the unit disc such that the measure
$ |f'(z)|^2(1-|z|^2)^pdA(z)$
is a
$p\lambda $
-Carleson measure. In this paper, we show that the corona theorem and the Wolff theorem hold for the multiplier algebra of Dirichlet–Morrey spaces.
Zoonotic Chlamydiae as rare causes of severe pneumonia
Authors: Imkamp Frank , Albini Sarah , Karbach Michael , Kimmich Nina , Spinelli Carlotta , Herren Sebastian , Sprecher Remy , Meier Karin , Borel Nicole 
Published: January 2022

Zoonotic species of the Chlamydiaceae family should be considered as rare pathogenic agents of severe atypical pneumonia. A fatal case of a severe pneumonia due to Chlamydia psittaci was traced back to pet birds, and pneumonia in a pregnant woman was attributed to abortions in a sheep and goat flock, being the source of Chlamydia abortus. The two SARS‑CoV‑2-negative pneumonia cases presented here were investigated in an inter-disciplinary approach involving physicians and veterinarians. State-of-art molecular methods allowed the identification and genotyping of zoonotic Chlamydiae.

DECOLONIAL EDUCATION: the landscape and the black History in the narratives of downtown Rio de Janeiro
Abstract
This article starts from the systematization of interdisciplinary pedagogical practices (Geography and History) carried out throughout 2019 at the Federal Center for Technological Education Celso Suckow da Fonseca (CEFET), Maria da Graça Unit, to dialogue and debate on racial issues and the decolonial teaching. With this in mind, three field trips were made: first to the National Museum of Fine Arts, then to the UNESCO World Heritage site known as Little Africa and finally to the Praça XV de Novembro region. The activity brought new perspectives on the landscape of the city of Rio de Janeiro and led students to reflect on changes and permanencies in the use of urban space. These mediations were embodied through a series of publications made by students on social networks.

Published: January 2022

Salah satu ciri perkotaan, khususnya kota metropolitan adalah kepadatan penduduk yang tinggi, sempitnya lahan, karena banyak lahan yang digunakan untuk pemukiman dan pembangunan infrastruktur, serta terbatasnya ruang terbuka hijau. Kebutuhan pangan di wilayah perkotaan meningkat seiring bertambahnya jumlah penduduk. Sedangkan hasil pertanian semakin rendah, karena lahan pertanian yang semakin sempit. Pemanfaatan lahan terbatas, terutama halaman rumah terus diupayakan untuk memenuhi kebutuhan pangan keluarga. Budidaya sistem akuaponik pada prinsipnya menghemat penggunaan lahan dan meningkatkan efisiensi pemanfaatan hara dari sisa pakan dan metabolisme ikan. Model akuaponik mini ini mengitegrasikan budidaya ikan dan sayuran sekaligus pada lahan yang terbatas. Hasil yang dirasakan oleh mitra pengabdian adalah panen ikan lele dan panen sayur kangkung setelah dua hingga tiga minggu perawatan.

Measurement report: Particle-size-dependent fluorescence properties of water-soluble organic compounds (WSOCs) and their atmospheric implications for the aging of WSOCs
Authors: Qin Juanjuan , Tan Jihua , Zhou Xueming , Yang Yanrong , Qin Yuanyuan , Wang Xiaobo , Shi Shaoxuan , Xiao Kang , Wang Xinming 
Published: January 2022

Abstract. Water-soluble organic compounds (WSOCs) play important roles in atmospheric particle formation, migration, and transformation
processes. Size-segregated atmospheric particles were collected in a rural area of Beijing. Three-dimensional fluorescence spectroscopy was used to
investigate the optical properties of WSOCs as a means of inferring information about their atmospheric sources. Sophisticated analysis on
fluorescence data was performed to characteristically estimate the connections among particles of different sizes. WSOC concentrations and the average
fluorescence intensity (AFI) showed a monomodal distribution in winter and a bimodal distribution in summer, with the dominant mode in the
0.26–0.44 µm size range in both seasons. The excitation–emission matrix (EEM) spectra of WSOCs varied with particle size, likely due to
changing sources and/or the chemical transformation of organics. Size distributions of the fluorescence regional integration (regions III and V) and
humification index (HIX) indicate that the humification degree or aromaticity of WSOCs was the highest in the particle size range of
0.26–0.44 µm. The Stokes shift (SS) and the harmonic mean of the excitation and emission wavelengths (WH) reflected that
π-conjugated systems were high in the same particle size range. The parallel factor analysis (PARAFAC) results showed that humic-like substances
were abundant in fine particles (< 1 µm) and peaked at 0.26–0.44 µm. All evidence supported the fact that the humification
degree of WSOCs increased with particle size in the submicron mode (< 0.44 µm) and then decreased gradually with particle size, which
implied that the condensation of organics occurred in submicron particles, resulting in the highest degree of humification in the particle size range of
0.26–0.44 µm rather than in the < 0.26 µm range. Synthetically analyzing three-dimensional fluorescence data could efficiently reveal
the secondary transformation processes of WSOCs.

Abstract. Water clarity serves as a sensitive tool for understanding the
spatial pattern and historical trend in lakes' trophic status. Despite the
wide availability of remotely sensed data, this metric has not been fully
explored for long-term environmental monitoring. To this end, we utilized
Landsat top-of-atmosphere reflectance products within Google Earth
Engine in the period 1984–2018 to retrieve the average Secchi disk depth (SDD) for each lake in
each year. Three SDD datasets were used for model
calibration and validation from different field campaigns mainly conducted
during 2004–2018. The red / blue band ratio algorithm was applied to map SDD
for lakes (>0.01 km2) based on the first SDD dataset, where R2=0.79 and relative RMSE (rRMSE) =61.9  %. The other two datasets were used to validate the temporal transferability of the SDD estimation model, which confirmed the stable performance of the model. The spatiotemporal dynamics of SDD were analyzed at the five lake regions and individual lake scales, and the average, changing trend, lake number and area, and spatial distribution of lake SDDs across China were presented. In 2018, we found the number of lakes with SDD <2 m accounted for the largest proportion (80.93 %) of the total lakes, but the total areas of lakes with SDD of <0.5 and >4 m were the largest, both accounting for about 24.00 % of the total lakes. During 1984–2018, lakes in the Tibetan–Qinghai Plateau region (TQR) had the clearest water with an average value of 3.32±0.38 m, while that in the northeastern region (NLR) exhibited the lowest SDD (mean 0.60±0.09 m). Among the 10 814 lakes with SDD results for more than 10 years, 55.42 % and 3.49 % of lakes experienced significant increasing and decreasing trends, respectively. At the five lake regions, except for the Inner Mongolia–Xinjiang region (MXR), more than half of the total lakes in
every other region exhibited significant increasing trends. In the eastern
region (ELR), NLR and Yungui Plateau region (YGR), almost more than 50 % of the lakes that displayed increase or decrease in SDD were mainly distributed in the area range of 0.01–1 km2, whereas those in the TQR and MXR were primarily concentrated in large lakes (>10 km2). Spatially, lakes located in the plateau regions generally
exhibited higher SDD than those situated in the flat plain regions. The
dataset is freely available at the National Tibetan Plateau Data Center

Human health care against COVID-19 via environmental management
Authors: Paital Biswaranjan 
Published: January 2022

Although vaccines are successfully developed against Severe Acute Respiratory Syndrome Coronavirus-19 (COVID-19), and many anticancer, anti-malarial, antibiotic drugs have been repurposed against the disease, it has been just impossible to save valuable human lives in specific conditions. Therefore, medical care has been developed against COVID-19 but not fully able to save human life from the disease. As a result, the third wave is noticed in many countries. Preventive methods such as social distancing, wearing masks, and hand salinization have been accepted as the main strategies to break the chain of the disease. Due to the reduction in pollution under less or no industrial and vehicular operations, water and air ecosystems have been restored in an unseen manner. Especially, NO<sub>2</sub>, SO<sub>2</sub> and particulate matters etc. modulated higher expression of angiotensin-converting enzyme 2, the receptor of Severe Acute Respiratory Syndrome Coronavirus -2 in humans have also been emphatically documented. Therefore, along with medical care, environmental protection (especially to regulate NO<sub>2</sub> emissions) along with practicing COVID-19 guidelines is to be maintained fully to combat COVID-19 the disease. Human beings must use this knowledge and experience as a spotlight to save nature in current and future times.
DIGITIZATION OF THE HAKKA ANCESTOR WORSHIP CEREMONY
Authors: Акоева Наталья Борисовна , Чэнь Лилун 
Published: January 2022

«Мировая церемония предков хакка» - одна из самых влиятельных церемоний поклонения предкам в Китае. В 2011 году это мероприятие было включено в Национальный список нематериального культурного наследия. Благодаря слиянию и сосуществованию нескольких моделей взаимодействия в «церемонии поклонения предкам» и точному пониманию намерений мультимодального взаимодействия синхронизировано представление многоканального восприятия (визуального, звукового и сенсорного). На основе Node.js и Three.js технологий авторами была реализована цифровая система для «церемонии поклонения предкам». Цифровая модель представляет действия в двух залах: Хуайцзу, где можно выразить свои чувства памяти и помолиться за свои семьи, и Юйпин, где можно произвести интерактивные операции, такие как подношение свечей, подношение благовоний и т.п. Тесты показывают, что в системе достигается баланс между производительностью и удобством для пользователя, что дает реальное решение для оцифровки нематериального культурного наследия ритуального типа. Цифровой контент церемонии не ограничен во времени и пространстве, не требует использования сторонних плагинов и имеет быструю доступность, что может способствовать быстрому распространению и развитию «Церемонии предков мира хакка».
The Hakka World Ancestor Ceremony is one of the most influential ancestor worship ceremonies in China. In 2011, this event was included in the National List of Intangible Cultural Heritage. Due to the fusion and coexistence of several interaction models in the "ancestor worship ceremony" and an accurate understanding of the intentions of multimodal interaction, the representation of multi-channel perception (visual, sound and sensory) is synchronized. Based on Node.js and Three.js technologies, the authors implemented a digital system for the "ancestor worship ceremony". The digital model represents actions in two halls: Huaizu, where you can express your feelings of memory and pray for your families, and Yuping, where you can perform interactive operations, such as offering candles, offering incense, etc. Tests show that the system achieves a balance between performance and user-friendliness, which provides a real solution for digitizing intangible cultural heritage of the "ritual" type. The digital content of the ceremony is not limited in time and space, does not require the use of third-party plug-ins and has rapid availability, which can contribute to the rapid spread and development of the "Ceremony of the Ancestors of the Hakka World".
