Revisiting matrix-based inversion of scanning mobility particle sizer (SMPS) and humidified tandem differential mobility analyzer (HTDMA) data
Authors: Petters Markus D. 
Published: December 2021

Abstract. Tikhonov regularization is a tool for reducing noise amplification
during data inversion. This work introduces RegularizationTools.jl,
a general-purpose software package for applying Tikhonov regularization
to data. The package implements well-established numerical algorithms
and is suitable for systems of up to ∼ 1000 equations.
Included is an abstraction to systematically categorize specific inversion
configurations and their associated hyperparameters. A generic interface
translates arbitrary linear forward models defined by a computer function
into the corresponding design matrix. This obviates the need to explicitly
write out and discretize the Fredholm integral equation, thus facilitating
fast prototyping of new regularization schemes associated with measurement
techniques. Example applications include the inversion involving data
from scanning mobility particle sizers (SMPSs) and humidified tandem
differential mobility analyzers (HTDMAs). Inversion of SMPS size distributions
reported in this work builds upon the freely available software
DifferentialMobilityAnalyzers.jl. The speed of inversion is
improved by a factor of ∼ 200, now requiring between
2 and 5 ms per SMPS scan when using 120 size bins. Previously reported
occasional failure to converge to a valid solution is reduced by switching
from the L-curve method to generalized cross-validation as the metric
to search for the optimal regularization parameter. Higher-order inversions
resulting in smooth, denoised reconstructions of size distributions
are now included in DifferentialMobilityAnalyzers.jl. This
work also demonstrates that an SMPS-style matrix-based inversion can
be applied to find the growth factor frequency distribution from raw
HTDMA data while also accounting for multiply charged particles.
The outcome of the aerosol-related inversion methods is showcased
by inverting multi-week SMPS and HTDMA datasets from ground-based
observations, including SMPS data obtained at Bodega Marine Laboratory
during the CalWater 2/ACAPEX campaign and co-located SMPS and HTDMA
data collected at the US Department of Energy observatory located
at the Southern Great Plains site in Oklahoma, USA. Results show
that the proposed approaches are suitable for unsupervised, nonparametric
inversion of large-scale datasets as well as inversion in real time
during data acquisition on low-cost reduced-instruction-set architectures
used in single-board computers. The included software implementation
of Tikhonov regularization is freely available, general, and domain-independent
and thus can be applied to many other inverse problems arising in
atmospheric measurement techniques and beyond.
ChAP 1.0: a stationary tropospheric sulfur cycle for Earth system models of intermediate complexity
Authors: Eliseev Alexey V. , Gizatullin Rustam D. , Timazhev Alexandr V. 
Published: December 2021

Abstract. A stationary, computationally efficient scheme ChAP 1.0 (Chemical and Aerosol Processes, version 1.0) for the sulfur cycle in the troposphere is developed. This scheme is designed for Earth system models of intermediate complexity (EMICs). The scheme accounts for sulfur dioxide emissions into the atmosphere, its deposition to the surface, oxidation to sulfates, and dry and wet deposition of sulfates on the surface. The calculations with the scheme are forced by anthropogenic emissions of sulfur dioxide into the atmosphere for 1850–2000 adopted from the CMIP5 dataset and by the ERA-Interim meteorology assuming that natural sources of sulfur into the atmosphere remain unchanged during this period. The ChAP output is compared to changes of the tropospheric sulfur cycle simulations with the CMIP5 data, with the IPCC TAR ensemble, and with the ACCMIP phase II simulations. In addition, in regions of strong anthropogenic sulfur pollution, ChAP results are compared to other data, such as the CAMS reanalysis, EMEP MSC-W, and individual model simulations. Our model reasonably reproduces characteristics of the tropospheric sulfur cycle known from these information sources. In our scheme, about half of the emitted sulfur dioxide is deposited to the surface, and the rest is oxidised into sulfates. In turn, sulfates are mostly removed from the atmosphere by wet deposition. The lifetimes of the sulfur dioxide and sulfates in the atmosphere are close to 1 and 5 d, respectively. The limitations of the scheme are acknowledged, and the prospects for future development are figured out. Despite its simplicity, ChAP may be successfully used to simulate anthropogenic sulfur pollution in the atmosphere at coarse spatial scales and timescales.
Identifying the dynamic evolution and feedback process of water resources nexus system considering socioeconomic development, ecological protection, and food security: A practical tool for sustainable water use
Authors: Tan Yaogeng , Dong Zengchuan , Guzman Sandra M. , Wang Xinkui , Yan Wei 
Published: December 2021

Abstract. The accelerated consumption of water resources caused by
the rapid increase in population and urbanization is intensifying the
complex interactions across water resources, socioeconomic development,
ecological protection, and food security (WSEF), which causes not only the
imbalance between water supply and demand but also the vulnerability of
both food and ecological systems. Therefore, identifying the dynamic
coevolution and feedback process is one of the most crucial ways of achieving the goal of sustainable water use. In this study, we developed an integrated modeling framework to better identify the dynamic interaction and coevolution process of the nexus across WSEF systems in the context of
sustainable water uses by coupling system dynamic (SD) model and
multi-objective optimization model. The SD model is used to simulate both
the dynamic interaction of each agent and the coevolution process of the
whole nexus system by positive/negative feedback loops. The multi-objective
optimization model is used to quantify the negative feedback loops of the SD model by generating the optimal scheme of different water users. Finally, the model uncertainty considering different weighting factors is analyzed. The framework is applied to the upper reaches of the Guijiang River basin, China. Results show that (i) the rapid economic growth increases the conflict between the water uses for socioeconomic development and ecological protection, intensifying the ecological awareness and resulting in more water shortages of socioeconomic and food agents, which is unable to support such rapid development. (ii) Once the economic growth rate decreases, water resources are able to support economic development with a decreased overload index and stable crop yield, which further contributes to water sustainability. (iii) The river ecological agent is the critical factor that affects the robustness of the model. (iv) The equal consideration of each water usage is the most beneficial to sustainable development. These results highlight the importance of water resources management, considering the tradeoffs across multiple stakeholders, and give a strong reference to policymakers for comprehensive urban planning.
The effectiveness of antibiotic cement-coated nails in post-traumatic femoral and tibial osteomyelitis – comparative analysis of custom-made versus commercially available nails
Authors: Garabano Germán , del Sel Hernán , Rodriguez Joaquin Anibal , Perez Alamino Leonel , Pesciallo Cesar Angel 
Published: December 2021

Abstract. Background: The first objective of this
retrospective study was to assess infection control rates in patients with
chronic post-traumatic osteomyelitis (CPTO) of the femur or tibia treated
with antibiotic cement-coated nails. The second objective was to compare the
efficacy of custom-made nails versus commercially available
antibiotic-coated nails in terms of infection control and need for
reoperation. Methods: We reviewed a consecutive series of CPTO
patients treated with antibiotic-coated nails who had a minimum follow-up of
24 months. We recorded the characteristics of the initial injury, the type
of nail used, cement–nail debonding, infecting microorganisms, operating
time, infection control, need for reoperation, and failure rate. We
performed a comparative analysis between nails manufactured in the operating
room (i.e., custom-made) and those commercially available. Results:
Thirty patients were included. The affected bones were the femur
(n=15) and the tibia (n=15). Twenty-one of the 30 initial
injuries were open fractures. Staphylococcus aureus was the most frequently
isolated microorganism (50 %). Sixteen patients were treated with
custom-made nails and 14 with commercially available antibiotic-coated
nails. At the time of extraction, four out of five custom-made antibiotic-coated
nails experienced cement–bone debonding. Commercial nails were associated
with shorter operating times (p<0.0001). The overall infection
control rate was 96.66 %. Eight (26.66 %) patients needed reoperation.
There was one failure (3.33 %) in the group treated with custom-made
antibiotic-coated nails. We did not find significant differences between
nail types in terms of reoperation, infection control, and failure rate.
Conclusions: The use of antibiotic cement-coated nails proved
useful in CPTO treatment. Commercially available nails had significantly
shorter operating times and did not present cement–bone debonding during
removal. Our results seem to indicate that both nail types are similar in
terms of infection control and reoperation rates.
Recent changes in London English. An overview of the main lexical, grammar and discourse features of Multicultural London English (MLE)
Authors: Palacios Martínez Ignacio Miguel 
Published: December 2021

This paper is intended to provide an overview of the main lexical, grammar and discourse features of the so-called Multicultural London English (MLE), a recent multiethnolect that can be regarded as a new development of London popular speech with the addition of traits from a pool of other sociolects and varieties of English, namely Caribbean and Jamaican English, and with a high proportion of young speakers. The data here analysed have been extracted from multiple sources, such as the London English Corpus (LOE), the Bergen Corpus of London Teenage Language (COLT), dictionaries, magazines, films, TV series, song lyrics and social media, mainly Twitter.
Particular attention is paid to those grammar and discourse features which can be considered as the most innovative, such as the quotative this is + pronoun, man used as a personal pronoun, the overuse of a set of vocatives (brother, mate, boy, guy(s), bastard, dickhead), the invariant tags innit and you get me, the adjectives proper and bare used as intensifiers, a high presence of negative vernacular forms (ain’t, third person singular don’t), never as negative preterite and a high proportion of negative concord structures. As regards lexis, a wide range of borrowings and loan words from other varieties and languages are recorded together with an excessive amount of general vague nouns and general extenders.

FDA approval of Pfizer-BioNTech: Evaluating the significance of mRNA vaccine approval
Authors: Monawwer Syed Abdullah , Naeem Raahim 
Published: December 2021

The COVID-19 pandemic has devastated the global demographics, claiming more than 4.8 million deaths globally as of October 2021. Mass vaccination is currently the best defense strategy against the virus, which has led to efforts towards the global distribution of COVID-19 vaccines. However, due to the urgency to inoculate, not all vaccines had received federal endorsement by the Food and Drug Administration (FDA) of the United States of America. The FDA is widely considered one of the foremost authorities on drug safety, which is why their ratification of an mRNA vaccine produced by Pfizer, Inc. and BioNTech is a landmark for vaccinology. Although the vaccine was already in distribution, vaccine hesitancy was exacerbated by the lack of timely FDA approval, resulting in the overall lower than expected vaccination rates. Another detrimental factor was distrust in COVID-19 vaccines, based on the widespread claims of adverse effects, despite the vaccine safety being demonstrated in multiple studies. Not only are these new vaccines on a pace to outperform the traditional attenuated virus vaccines, their underlying technology and the use of the RNA molecule ushers in a new era, in which vaccines can be applied and adjusted quicker and for a broader spectrum of targets.

Published: December 2021

In a highly competitive manufacturing environment, it is critical to balance production time and cost simultaneously. Numerous attempts have been made to provide various solutions to strike a balance between these factors. However, more effort is still required to address these challenges in terms of labour productivity. This study proposes an integrated substitution and management improvement technique for enhancing the effectiveness of labour resources and equipment. Furthermore, in the context of time-cost optimization with optimal labour productivity, an extremal-micro genetic algorithm (Ex-μGA) model has been proposed. A real-world case from the labour-intensive medium-scale bus body fabricating industry is used to validate the proposed model performance. According to the results, the proposed model can optimize production time and cost by 34 % and 19 %, respectively, while maintaining optimal labour productivity. In addition, this study provides an alternative method for dealing with production parameter imbalances and assisting production managers in developing labour schedules more effectively.

De werkzaamheden van de Eerste Kamer: een getalsmatige benadering
In de media duikt regelmatig het commentaar op dat de Eerste Kamer zich steeds politieker opstelt en steeds meer op de Tweede Kamer begint te lijken. Dit artikel beoogt te abstraheren van staatrechtelijke analyses van individuele politieke casus en de werkzaamheden van de Eerste Kamer in de voorbije twintig jaar meer cijfermatig en vanuit een vogelvluchtperspectief te bezien. In dat kader zijn tellingen gedaan op het niveau van Senatoren en fracties, van de Kamer en van de Kamercommissies. De gepresenteerde cijfers leveren niet bepaald het beeld op dat zich in deze periode ingrijpende wijzigingen hebben voorgedaan in de werkwijzen en opstelling van Senatoren. Het politieke handwerk laat zich echter moeilijk vatten in statistieken. Idealiter baseren onderzoeken naar een eventueel veranderende rol van de Eerste Kamer zich daarom op kwantitatief én kwalitatief onderzoek.
