Authors: Avramchikova Nadezhda , Erygin Yuri , Rozhnov Ivan , Erygina Lilia , Ivanov Denis
Published: August 2023

Globalization is a process of worldwide economic, political and cultural integration and unification. The authors determined that the processes of globalization are due to economic feasibility. But, at the same time, since the effects of globalization are distributed, as a rule, unevenly and cause contradictions in the financial sector, the excessive integration and interdependence of countries exacerbate the crisis in social development. It is noted that, due to the evolution of social development, all states must to participate in the processes of globalization, however, one should adhere to a policy to reduce the impact of global problems at the level of an individual country and around the world. It is possible to avoid the negative impact of global processes by systematizing them and analyzing in detail the causes of problems. A study was made of the causes of global problems and their systematization was carried out according to the main features. It is concluded that states face the difficult task of finding new forms of interaction or transforming and improving existing elements of interaction between various international institutions and finding mutually beneficial compromises.

Authors: Krylov Pavel A. , Tretyakova Anna V.
Published: August 2023

Fighting against desertification is one of the priorities in the world. In areas subject to desertification, there is a deficiency of heavy metal ions, such as Fe, Mn, Zn, Co, Cu and Ni, which are involved in the implementation of metabolic processes in woody plants. In this study, an assessment metal-dependent proteins and an analysis of the structural homology between them in Quercus robur, Robinia pseudoacacia, Gleditsia triacanthos, Ulmus pumila and Fraxinus excelsior used in agroforestry of arid territories was carried out. Bioinformatic analysis included multiple alignment of amino acid sequences using the Ugene program by the ClustalW algorithm (BLOSUM62 matrix). According to the results of studying the plants metalloproteome, it was found that Quercus robur has 18 proteins, Robinia pseudoacacia – 24, Gleditsia triacanthos – 3, Ulmus pumila – 19, Fraxinus excelsior – 14 metal-dependent proteins. The main part of metal-dependent proteins is involved in photosynthesis and respiration, in particular Fe, Zn and Co-dependent proteins. Multiple alignment showed a high degree of protein homology between species of woody plants, where similarity varied from 65% to 100%. The results can be used to create new agricultural technologies for productivity management and the formation of adaptation to adverse environmental factors.
Forms of mercury in soils and its accumulation by herbs in the zone of influence of the sludge storage of a chlor-alkali plant (Southern Baikal region)
Authors: Gordeeva Olga , Pastukhov Mikhail
Published: August 2023

Total concentrations of Hg in soils and the narrow-leaved fireweed Chamaenerion angustifolium L., as well as the forms of Hg presence in soils by the method of sequential extractions were examined to study the processes of mobilization-immobilization of Hg in the soils of the territory of the chlor-alkali plant sludge storage and the features of the bioaccumulation of this element in herbs. The determination of Hg in all samples was carried out by the atomic absorption method. High concentrations of Hg in soils near the sludge storage have been established. In almost all soil samples the amount of Hg is above the regional background. Fractionation showed that Hg in soils is found mainly in organic, strongly bound and sulfide fractions. Due to the low concentrations of Hg mobile fractions, water- and acid-soluble, a relatively low accumulation of Hg in Chamaenerion angustifolium L. was found, which was also facilitated by the barrier properties of the herb roots. Nevertheless, the accumulation of predominantly organic and strongly bound forms of Hg in soils indicates a high potential for Hg mobilization from these fractions due to changes in various physicochemical and biogeochemical properties of soils.

Published: August 2023

Uzbekistan is one of the most water resources limited regions and it needs better sustainable water management. The global ecological problem as the Aral Sea disaster makes it more urgent not only for one nation but also for the all CentralAsian region. Region needs to be developed by following SDG and the same time to save water resources. The balance of the ground water resources in the region is environmentally safe and enough by quantity and also hydrologically. It is due to the use of huge number of the water wells as artesian and also drainage wells. At the UZWATER National center of SamSACU the studies on the clogging deposits as the chemically and mineralogically multicomponent complex composition particles and their removal/declogging rehabilitation of the water wells are carried out. A rehabilitation technology effective for the region with dry and hot climate and environmentally safe water wells by using complex reagents such as oxyethylidenediphosphonic acid and nitrilotrimethylphosphonic acid in combination with carbon dioxide will help to remove of the clogging deposits and a stable filtration process and work of the water wells.

Authors: Sharafutdinov Ulugbek , Razhabboev Ibodulla , Kadirova Zukhra , Daminova Shakhlo , Koldarov Albert , Atamuratova Malokhat
Published: August 2023

The aim of the study is to elucidate the effect of simultaneous sorption of uranium with different concomitant impurities that are contained in underground leaching solutions (sulfates, chlorides, nitrates, phosphates, silicates, iron, aluminum, and manganese) at pH = 1.2. Different sorption isotherms are studied for the uranium sorption by the strongly basic anion-exchange resin (BO020): (i) uranium and a number of concomitant impurities; (ii) uranium in the presence of the studied impurities. The negative effect of impurities is manifested at low uranium concentrations. With an increase in uranium concentration, the depressing effect of impurities (Al, Fe, Mn) becomes less. The most negative effect is exerted by nitrates in the amount of 0.4 g/L, silicates - 0.3 and 1 g/L, chloride -1 g/L. The phosphorus contributes to better sorption of uranium in the low concentration range of 0.02 to 0.200 g/L but becomes a depressant at higher concentrations.

Published: August 2023

The article considers the problem of propagation of proper normal waves in a two-layer pipe, paying to attention the rheological properties of the material. The main purpose of the work is to develop a methodology, an algorithm for investigation the problems of wave propagation in extended two-layer dissipatively inhomogeneous cylindrical structures. The main integro-differential equations in the article are obtained on the basis of methods of the theory of visco-elasticity. In the course of the study, the method of separation of variables, the freezing method, the Muller method and the Godunov orthogonal run method were used. In this paper, for structurally inhomogeneous extended cylindrical mechanical systems, the dependences of several modes (three and four) of the complex phase velocity (real and imaginary parts) on the wave number are comparatively estimated; the results of calculations are compared with experimental and theoretical data of other researchers, and the use of asymptotic and numerical methods for solving dispersion equations with complex output parameters is justified.

Published: August 2023

The article presents the results of theoretical studies of vertical and deflecting vibrations of two-stroke screws with a wavy surface and conveyor screws with a curved base and an elastic element. Based on the analysis of the obtained graphs of the relations of laws and motion parameters, their optimal values are justified. Here, the options for applying rubber gaskets to bearing bearings are considered in two versions, that is, with the same and two different types of stencils. When the rubber bushings of the bearing supports are taken in two different elasticities, the change laws of the vibration of the screw are obtained depending on the size of the supports, the moment of inertia of the screw and the change of the technological resistance force.

Published: August 2023

The article considers a method for solving the problem of structural design of modernized networks of non-request measuring instruments of a ground-based control complex for navigation stations of a space complex. The object of research is satellite geodetic networks using mobile monitoring stations. The type of such networks is information and control systems distributed over the territory, dispersed in space. Structurally, they are determined by multifunctional sets of stationary and mobile elements with advanced technical means for receiving, transmitting and processing information. It is shown that in the structural design of satellite geodetic networks, special attention is paid to the cost of the network, since this can significantly reduce the cost of field work associated with the use of mobile monitoring stations. An analysis of various approaches to the formation of the structure of such systems was carried out, which showed that the tasks of formation can be divided into two groups: the formation of the topological structure of the system and the formation of the functional structure of the system. The paper presents the stages of the analytical and simulation procedure, which includes optimization and simulation models and allows solving the problem of structural design of satellite geodetic networks.

Published: August 2023

A dependence of the distance between the rolls on the radis of the roll, the thickness of the processed material, and the coefficient (angle) of friction of the processed material on the surface of the roll coating were theoretically studied. An experimental study revealed the dependence of the distance between the rolls on the intensity of the load, the radius of the roll, and the thickness of the material being processed. It was found that with an increase in the roll radius and load intensity, and with a decrease in the thickness of the material being processed, the distance between the rolls decreases.

Models of language production and the temporal organization of
lexical access
Authors: Schiller Niels O. , Alario F.-Xavier
Published: August 2023

This chapter focusses on models of language
production and the temporal organization of the processes involved
in lexical access. Albert Costa contributed significantly to
advancing our understanding of lexical access. Through the
investigation of multilingual speakers, he added an important
dimension to this discussion. Here, we provide a discussion of
discrete and cascaded/interactive accounts of lexical access and
summarize some of the crucial experimental evidence that has been
offered for and against these different theories, roughly over the
years when Albert contributed to these debates. We will also discuss
whether or not lexical selection is competitive and what research on
multilingual speech production contributed to our knowledge on
lexical access. The discussion is mainly restricted to behavioral
data, with some references to electrophysiological studies. We
conclude that considering the experimental evidence a strict version
of discrete processing models is difficult to maintain. Research on
bilingual language production has made important contributions to
the discussion, however, the picture is not yet complete.
Effects of foreign-accented speech on language comprehension
processes and social cognition*
Authors: Rodriguez-Cuadrado Sara , Romero Rivas Carlos
Published: August 2023

In this chapter, we review the literature on how
foreign-accented speech modulates cognitive processes related to
language comprehension and describe the interactions between native
and non-native speakers. First, we focus on how language
comprehension processes are modulated when native listeners listen
to foreign-accented speakers. Whilst the results about
acoustic-phonetic and syntactic processing are relatively consistent
throughout the literature on the subject, there is currently a
debate on what the effects of foreign-accented speech are on
lexical-semantic processing. Secondly, we analyze the literature on
how foreign listeners process foreign-accented speech, a field of
research that has grown recently. Then, we discuss how native and
non-native speakers align with one another during verbal
interactions. Finally, we examine the cognitive biases that native
listeners show when interacting with non-native speakers that
modulate social cognition processes.

This book addresses an under-researched area within populism studies: the discourse of supporters of populist parties. Taking the 2019 European elections as their case study, the authors analyse how supporters in eleven different countries construct identities and voting motivations on social media. The individual chapters comprise a range of methods to investigate data from different social media platforms, defining populism as a political strategy and/or practice, realised in discourse, that is based on a dichotomy between “the people”, who are unified by their will, and an out-group whose actions are not in the interest of the people, with a leader safeguarding the interests of the people against the out-group. The book identifies what motivates people to vote for populist parties, what role national identities and values play in those motivations, and how the social media postings of populist parties are recontextualised in supporters’ comments to serve as a voting motivation.
Scotland
Authors: Demata Massimiliano
Published: August 2023

This chapter analyses the discourse and political
identity of the supporters of the SNP (Scottish National Party) as expressed
in their responses to the tweets published on the party’s official Twitter
account (@theSNP) during the 2019 European election campaign. The chapter
uncovers the way SNP supporters choose to display their position vis-à-vis
the different issues raised by the party’s eclectic political programme by
backing, ignoring or criticising the official party line. Most posts by the
SNP leadership avoided explicit mentions of independence but rather emphasised
the necessity for Scotland to reject Brexit and remain in the EU. However,
these posts are often re-negotiated by SNP supporters on the basis of their
own identity as European or, most often, Scottish, as they foregrounded
independence as the ideological backbone of their brand of populism.

In this final chapter, we will answer our overall research
questions, comparing findings across the various contexts investigated in
the preceding chapters. In doing so, we will point out what voting
motivations, aspects of national identities and ways of recontextualising
original posts are shared across countries and which ones are specific to a
given political context. This comparison will be followed by a review of the
different methodologies that we used and a discussion on how far a given
methodology may have influenced the findings. We will reflect on ethical
considerations before the chapter finishes with a section on the
contributions and limitations of the research and an outlook on possible
future work.
Germany
Authors: Miglbauer Marlene
Published: August 2023

This chapter addresses how populist conceptualisations
and right-wing populist rhetoric are drawn upon by Alternative für
Deutschland (Alternative for Germany, AfD) supporters on Facebook when
expressing support for AfD and constructing in- and outgroups. 1479 direct
replies to the original post covering the election campaign for the 2019 EU
election in four threads were selected from the official AfD Facebook page.
Findings disclose that populist conceptualisations such as ‘saving’ and
speaking for ‘the people’, denouncing the elite and belittling outgroups are
crucial drivers for voting AfD and identity constructions of in- and
outgroups. AfD supporters draw on linguistic resources specific to social
media (e.g. emojis) and populist discourse in their comments resulting in
populist and right-wing rhetoric being manifest in AfD supporters’
discourse.
Croatia and Slovenia
Authors: Šarić Ljiljana
Published: August 2023

This chapter analyses the argumentation of populist
parties’ supporters in Croatia and Slovenia in the context of the 2019
European Parliament elections. It focuses on two countries that are rather
different in terms of populist tendencies, juxtaposing right-wing (Slovenia)
and left-wing (Croatia) supporters’ voices. The analysis concentrates on the
topics and motivations most frequently addressed in Facebook comments on an
election video posted by the Croatian leftist populist party Živi zid, and
online comments on news stories posted by people supporting right-wing
populist parties in Slovenia. The focus is on examining identities that they
discursively construct for themselves and their political favourites on the
one hand, and for Others (e.g., other parties and their supporters) on the
other.
Italy
Authors: Reggi Valeria
Published: August 2023

The Italian Northern League (Lega Nord),
now simply “Lega”, and its leader Matteo Salvini exemplify the tenets and
discursive style of right-wing populism, in which polarised discourse is
imbued with nationalistic overtones. The study focuses on the comments on
Salvini’s posts on Twitter by his supporters in the last six weeks before
the European elections of 2019. The aim is to foreground what motivations
encouraged the support for populist parties, with a focus on the role played
by national identity and by the strategies that were chosen to
recontextualise the original posts. To achieve this purpose, the textual
and visual components of sample comments are analysed qualitatively and
quantitatively under the lens of multimodal discourse analysis in order to
determine which populist themes they reproduced and, drawing on appraisal
analysis, understand the evaluation most frequently associated with
them.
The autistic dialogue
Authors: Sterponi Laura , Barbetta Pietro , Valtellina Enrico
Published: August 2023

From his early texts on language, consciousness, and
ideology, to his later contributions to literary criticism, Mikhail
Bakhtin’s theory centers speech in the dynamics of communicative exchanges.
This chapter considers how Bakhtinian notions such as dialogue,
double-voicing, and heteroglossia offer significant analytic purchase for
understanding autistic phenomena, notably autistic language and autistic
semiosis more broadly, what we refer to as autistic voice.
By way of empirical demonstration, the authors examine everyday verbal
exchanges between autistic children, their family members, and tutors in
home contexts. These verbal exchanges were video recorded, transcribed and
analyzed employing an integrated methodology, which combines linguistic,
discourse, and acoustic analyses, highlighting the dialogues’ simultaneous
singularity and multiplicity. Our examination yields an understanding of the
autistic voice as inherently polyphonic, oriented to dialogue and
creativity.
Death and traumatic affect on Twitter
Authors: Hughes Jessica M.F.
Published: August 2023

References to death appear frequently in activist
discourse. Activists make death matter on- and offline when they speak the
names of people killed, hold die-ins and vigils, mention the number of lives
lost, and tell the stories or share pictures of those who have died. This
chapter examines how death materializes in digital activism on Twitter.
Using a relational ontological approach (Cooren, 2018) to analyze agents and relationships evident in
tweets about death in her own Twitter profile, the author works to
understand how references to death are used in digital disability activism
and what kinds of affective impact references to death might have on Twitter
users. Taking as a focal point disability activists’ responses to comments
about COVID-19 deaths made by the Director of the US Centers for Disease
Control and Prevention, the analysis demonstrates how references to death
are used to mobilize activists, hold authorities to account, and reframe
states of affairs to center the needs of vulnerable community members.
Putting this case study in dialogue with other references to death on
Twitter reveals the power of traumatic affect (Richardson, 2018), a force that materializes in the
body and positions audience members in moral relation with those who have
died.
(Im)politeness and plot advancement in screen translation
Authors: Pak Kamilla
Published: August 2023

This contribution explores the workings of linguistic (im)politeness in plot advancement in the context of audiovisual translation with a focus on English-Korean film subtitling, which represents a transfer between considerably remote linguacultures that rely on very different pragmalinguistic means of expressing interpersonal meanings. Challenges of interlingual subtitling are associated with cultural asynchrony both between the source and target cultures and between the verbal component recreated in a different language and the original semiotic system. The discussion is based on examples from relatively recent mainstream fiction films that demonstrate some of the solutions deployed by screen translators in order to capture and re- or co-create the interpersonal effects of the original that have direct bearing on the general plot development.
Chef knows best
Authors: Gordon Cynthia , Nguyen Naomee-Minh
Published: August 2023

Our analysis of translation, broadly understood, on an episode of My Family Feast – an Australian TV series hosted by British celebrity chef Sean Connolly that highlights the cultures and cuisines of immigrant Australians – shows how the family’s recipes are constructed as unfamiliar and “exotic” while the chef’s ultimate professional – and white, Western, and male – authority over (their) food is maintained. In the episode, the chef assists members of a Vietnamese-Australian family as they prepare dishes for a cultural festival. Extending Heritage’s (2012) “epistemics in action” and linking it to Tovares’ (2005, 2020/2021) “intertextuality in action,” we demonstrate how ingredient quantities are introduced and translated through speech act and action sequences (e.g., query/response, cooking action/assessment), translations between Vietnamese and English (in subtitling especially), and the chef’s voiceover metacommentary.
Mechanical and magnetocaloric adjustable properties of Fe3O4/PET deformed nanoparticle film
Authors: Fan 范 Fengguo 凤国 , Duan 段 Lintong 林彤
Published: August 2023

The flexibility of nanoparticle films is a topic of rapidly growing interest in both scientific and engineering researches due to their numerous potential applications in a broad range of wearable electronics and biomedical devices. This article presents the elucidation of the properties of nanoparticle films. Here, a flexible film is fabricated based on polyethylene terephthalate (PET) and magnetic iron oxide at the nanoscale using layer-by-layer technology. The 2D thin flexible film material can be bent at different angles from 0° to 360°. With an increase in elastic deformation angles, the magnetocaloric effect of the film gradually increases in the alternating magnetic field. The test results from a vibrating sample magnetometer and a low-frequency impedance analyzer demonstrate that the film has a good magnetic response and anisotropy. The magnetocaloric effect and magnetic induction effect are controlled by deformation, providing a new idea for the application of elastic films. It combines the flexibility of the nanoparticle PET substrate and, in the future, it may be used for skin adhesion for administration and magnetic stimulation control.
Special breathing structures induced by bright solitons collision in a binary dipolar Bose–Einstein condensates
Authors: Zhang 张 Gen 根 , Lv 吕 Li-Zheng 李政 , Gao 高 Peng 鹏 , Yang 杨 Zhan-Ying 战营
Published: August 2023

We numerically investigate the breathing dynamics induced by collision between bright solitons in a binary dipolar Bose–Einstein condensates, whose dipole–dipole interaction and contact interaction are attractive. We identify three special breathing structures, such as snakelike special breathing structure, mixed breathing structure, and divide breathing structure. The characteristics of these breathing structures can be described by breathing frequency Ω, maximum breathing amplitude A and lifetime τ, which can be manipulated by atomic number Ni
and interspecies scattering length a
12. Meanwhile, the above breathing structures can realize the process of quasi-transition with a reasonable Ni
and a
12. Additionally, the collision of two special breathing structures also can bring more abundant breathing dynamics. Our results provide a reference for the study of soliton interactions and deepen the understanding of soliton properties in a binary dipolar Bose–Einstein condensates.
Grain-refining effects and mechanism of novel Al-Nb-B refiner on Al-Mg-Si alloy: phase-field simulation and experiment study
Authors: Jun Li , Haitao Jiang , Xiaoyan Wu
Published: August 2023

In this paper, the grain-refining effect of Al-Nb-B refiner in wrought Al alloys and corresponding refining mechanism was investigated using phase-field simulation and experiment methods. Through experimental statistics and data correction, the seed radius introduced by Al-Nb-B refiner into Al alloy melt and the corresponding quantitative density distribution data were obtained, and a seed density model (SDM) model has been established. On this basis, a multi-phase field method (MPFM) combined with the calculation of phase diagram (CALPHAD) has been employed to simulate the α-Al grain evolution of Al-Mg-Si alloy during the solidification process with the help of thermodynamic database. Experimental studies showed that the addition of 0.03 wt% Nb (Adding by Al-1.93Nb-0.22B master alloy) significantly reduced the grain size from 956.4 μm to about 219.4 μm, and the grain size slowly decreased to 192.3 μm by continuing to add refiner to 0.09 wt% Nb. Meanwhile, the simulation results demonstrated that after the addition of refiners, dendrite morphology transformed from the relatively developed dendrites with secondary and tertiary dendrites to a fine and uniform equiaxed shape. Simulation and experimental studies showed quantitative agreement. In addition, the results also prove that the addition of Al-Nb-B refiner can provide high-quality and stable heterogeneous nucleation particles.

The frequency of vanadium dioxide (VO2) oscillators is a fundamental figure of merit for the realization of neuromorphic circuits called oscillatory neural networks (ONNs) since the high frequency of oscillators ensures low-power consuming, real-time computing ONNs. In this study, we perform electrothermal 3D technology computer-aided design (TCAD) simulations of a VO2 relaxation oscillator. We find that there exists an upper limit to its operating frequency, where such a limit is not predicted from a purely circuital model of the VO2 oscillator. We investigate the intrinsic physical mechanisms that give rise to this upper limit. Our TCAD simulations show that it arises a dependence on the frequency of the points of the curve current versus voltage across the VO2 device corresponding to the insulator-to-metal transition (IMT) and metal-to-insulator transition (MIT) during oscillation, below some threshold values of

. This implies that the condition for the self-oscillatory regime may be satisfied by a given load-line in the low-frequency range but no longer at higher frequencies, with consequent suppression of oscillations. We note that this variation of the IMT/MIT points below some threshold values of

is due to a combination of different factors: intermediate resistive states achievable by VO2 channel and the interplay between frequency and heat transfer rate. Although the upper limit on the frequency that we extract is linked to the specific VO2 device we simulate, our findings apply qualitatively to any VO2 oscillator. Overall, our study elucidates the link between electrical and thermal behavior in VO2 devices that sets a constraint on the upper values of the operating frequency of any VO2 oscillator.
Monthly virtual water transfers on the U.S. electric grid

Published: August 2023

Water consumed by power plants is transferred virtually from producers to consumers on the electric grid. This network of virtual transfers varies spatially and temporally on a sub-annual scale. In this study, we focused on cooling water consumed by thermoelectric power plants and water evaporated from hydropower reservoirs. We analyzed blue and grey virtual water flows between balancing authorities in the United States electric grid from 2016 to 2021. Transfers were calculated using thermoelectric water consumption volumes reported in Form EIA-923, power plant data from Form EIA-860, water consumption factors from literature, and electricity transfer data from Form EIA-930. The results indicate that virtual water transfers follow seasonal trends. Virtual blue water transfers are dominated by evaporation from hydropower reservoirs in high evaporation regions and peak around November. Virtual grey watertransfers reach a maximum peak during the summer months and a smaller peak during the winter. Notable virtual blue water transfers occur between Arizona and California as well as surrounding regions in the Southwest. Virtual grey water transfers are greatest in the Eastern United States where older, once-through cooling systems are still in operation. Understanding the spatial and temporal transfer of water resources has important policy, water management, and equity implications for understanding burden shifts between regions.
Quantum vector fields via quantum doubles and their applications
Authors: Gurevich Dimitry , Saponov Pavel
Published: August 2023

By treating generators of the reflection equation algebra corresponding to a Hecke symmetry as quantum analogs of vector fields, we exhibit the corresponding Leibniz rule via the so-called quantum doubles. The role of the function algebra in such a double is attributed to another copy of the reflection equation algebra. We consider two types of quantum doubles: these giving rise to the quantum analogs of left vector fields acting on the function algebra and those giving rise to quantum analogs of the adjoint vector fields acting on the same algebra. Also, we introduce quantum partial derivatives in the generators of the reflection equation algebra and then at the limit

Published: August 2023

We assessed the risk of acquiring severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from household and community exposure according to age, family ties, and socioeconomic and living conditions using serological data from a nationwide French population-based cohort study, the Epidémiologie et Conditions de Vie (EpiCoV) Study. A history of SARS-CoV-2 infection was defined by a positive anti-SARS-CoV-2 enzyme-linked immunosorbent assay immunoglobulin G result in November–December 2020. We applied stochastic chain binomial models fitted to the final distribution of household infections to data from 17,983 individuals aged ≥6 years from 8,165 households. Models estimated the competing risks of being infected from community and household exposure. The age group 18–24 years had the highest risk of extrahousehold infection (8.9%, 95% credible interval (CrI): 7.5, 10.4), whereas the oldest (≥75 years) and youngest (6–10 years) age groups had the lowest risk, at 2.6% (95% CrI: 1.8, 3.5) and 3.4% (95% CrI: 1.9, 5.2), respectively. Extrahousehold infection was also associated with socioeconomic conditions. Within households, the probability of person-to-person transmission increased with age, from 10.6% (95% CrI: 5.0, 17.9) among children aged 6–10 years to 43.1% (95% CrI: 32.6, 53.2) among adults aged 65–74 years. Transmission was higher between partners (29.9%, 95% CrI: 25.6, 34.3) and from mother to child (29.1%, 95% CrI: 21.4, 37.3) than between individuals related by other family ties. In 2020 in France, the main factors identified for extrahousehold SARS-CoV-2 infection were age and socioeconomic conditions. Intrahousehold infection mainly depended on age and family ties.

Published: August 2023

Motivation

Single-cell sequencing technology has become a routine in studying many biological problems. A core step of analyzing single-cell data is the assignment of cell clusters to specific cell types. Reference-based methods are proposed for predicting cell types for single-cell clusters. However, the scalability and lack of preprocessed reference datasets prevent them from being practical and easy to use.

Results

Here, we introduce a reference-based cell annotation web server, CellAnn, which is super-fast and easy to use. CellAnn contains a comprehensive reference database with 204 human and 191 mouse single-cell datasets. These reference datasets cover 32 organs. Furthermore, we developed a cluster-to-cluster alignment method to transfer cell labels from the reference to the query datasets, which is superior to the existing methods with higher accuracy and higher scalability. Finally, CellAnn is an online tool that integrates all the procedures in cell annotation, including reference searching, transferring cell labels, visualizing results, and harmonizing cell annotation labels. Through the user-friendly interface, users can identify the best annotation by cross-validating with multiple reference datasets. We believe that CellAnn can greatly facilitate single-cell sequencing data analysis.

Availability and implementation

The web server is available at www.cellann.io, and the source code is available at https://github.com/Pinlyu3/CellAnn_shinyapp.
