Losses, hopes, and expectations for sustainable futures after COVID
Authors: Lewandowsky Stephan , Facer Keri , Ecker Ullrich K. H. 
Published: November 2021

AbstractThe COVID-19 pandemic has caused immense distress but also created opportunity for radical change. Two main avenues for recovery from the pandemic have been discussed: A “back to normal” that foregrounds economic recovery, and a sustainable and progressive “build back better” approach that seeks to address global problems such as inequality and climate change. The article reports two experiments conducted on representative British and American samples (N = 600 andN = 800, respectively, for the two experiments) that show that people in both countries overall prefer a progressive future to a return to normal, although that preference is stronger on the political left and center-left with ambivalence prevailing on the right. However, irrespective of political leanings, people consider a return to normal more likely than a progressive future. People also mistakenly believe that others want the progressive scenarios less, and the return to normal more, than they actually do. The divergence between what people want and what they think others want represents an instance of pluralistic ignorance, which arises when public discourse is not reflecting people’s actual opinions. Publicizing public opinion is thus crucial to facilitate a future with broad support. In additional open-ended items, participants cited working from home, reduced commuting, and a collective sense of civility as worth retaining post pandemic.
Queering the web archive: A xenofeminist approach to gender, function, language and culture in the London French Special Collection
Authors: Huc-Hepher Saskia 
Published: November 2021

AbstractBased on the author’s experience of curating a collection of migrant community web objects within the UK Web Archive, this paper combines conceptual interrogation with empirical analysis. The central premise is that the incorporation of multilingual, diasporic micro-archives serves to queer the anglophone UK Web Archive, or “patriarchive”, by dismantling steadfast binaries and implicit postcolonial hegemonies. The article challenges Jacques Derrida’s contention that themal d’archiveis the result of the archive’s ‘troubling’ duality, and posits, on the contrary, that such boundary-crossings are the very incarnation of a positive, transgressive form of xenofeminism (XF). From the dualism at the origin of the archive itself, to that comprised in the concept of genre/gender, and from the spatiotemporal in-betweenness of the archived diasporic (web)site to the translanguaging present therein, the article demonstrates how the diasporic micro-archive is the embodiment of a non-binary, trans-inclusive XF ideology. Taking French migrant women’s blogs preserved in the London French Special Collection as a primary source and examining their transformation over time, the paper explores how blog repurposing can be apprehended as a technomaterialist XF act and how the blogs’ increasing multimodal translanguaging bears witness to a form of culturo-linguistic transitioning that transcends binary hybridity.
A deep-learning model for predictive archaeology and archaeological community detection
Authors: Resler Abraham , Yeshurun Reuven , Natalio Filipe , Giryes Raja 
Published: November 2021

AbstractDeep learning is a powerful tool for exploring large datasets and discovering new patterns. This work presents an account of a metric learning-based deep convolutional neural network (CNN) applied to an archaeological dataset. The proposed account speaks of three stages: training, testing/validating, and community detection. Several thousand artefact images, ranging from the Lower Palaeolithic period (1.4 million years ago) to the Late Islamic period (fourteenth century AD), were used to train the model (i.e., the CNN), to discern artefacts by site and period. After training, it attained a comparable accuracy to archaeologists in various periods. In order to test the model, it was called to identify new query images according to similarities with known (training) images. Validation blinding experiments showed that while archaeologists performed as well as the model within their field of expertise, they fell behind concerning other periods. Lastly, a community detection algorithm based on the confusion matrix data was used to discern affiliations across sites. A case-study on Levantine Natufian artefacts demonstrated the algorithm’s capacity to discern meaningful connections. As such, the model has the potential to reveal yet unknown patterns in archaeological data.
Probing the adsorption behavior and free energy landscape of single-stranded DNA oligonucleotides on single-layer MoS2 with molecular dynamics
Authors: Saikia Nabanita 
Published: November 2021

Abstract
Interfacing single-stranded DNA (ssDNA) with 2D transition metal dichalcogenides are important for numerous technological advancements. However, the molecular mechanism of this process, including the nature of intermolecular association and conformational details of the self-assembled hybrids is still not well understood. Here, atomistic molecular dynamics simulation is employed to study the distinct adsorption behavior of ssDNA on a single-layer MoS2 in aqueous environment. The ssDNA sequences [T10, G10, A10, C10, U10, (GT)5, and (AC)5] are chosen on the basis that short ssDNA segments can undergo a spontaneous conformational change upon adsorption and allow efficient sampling of the conformational landscape. Differences in hybridization is attributed to the inherent molecular recognition ability of the bases. While the binding appears to be primarily driven by energetically favorable van der Waals π-stacking interactions, equilibrium structures are modulated by the ssDNA conformational changes. The poly-purines demonstrate two concurrently competing π-stacking interactions: nucleobase–nucleobase (intramolecular) and nucleobase–MoS2 (intermolecular). The poly-pyrimidines, on the other hand, reveal enhanced π-stacking interactions, thereby maximizing the number of contacts. The results provide new molecular-level understanding of ssDNA adsorption on the MoS2 surface and facilitate future studies in design of functional DNA/MoS2 structure-based platforms for DNA sequencing, biosensing (optical, electrochemical, and electronic), and drug delivery.

Abstract

Objective. The aim of this prospective cohort study, performed during a 10 d training camp, was to analyze the effect of a series of successive speed-power training sessions on the concurrent circadian changes in resting leg skin temperature and blood creatine kinase (CK) levels and to determine the correlation between them. Approach. Seventeen elite sprinters, aged 22–31 years, were examined. Every morning and evening, capillary blood samples were drawn to assay CK levels. Lower limb skin temperature was measured simultaneously, and thermal images were taken using an infrared camera. Main results. From the first day of the training camp, the base temperature levels began to drop to obtain a significant reduction from the 6th day (male) and from the 8th day (female) to the end of the camp. Simultaneously, CK levels increased in the male group from 8th to the end of the camp, but it did not change significantly in females. Regarding the circadian rhythm, the CK levels always rose during the day and declined during the night. The temperature decreased during the day and increased during the night until the 6th day. After that, the temperature changed oppositely till the end of camp, i.e. it increased during the day and decreased during the night. This could suggest that the training microcycle should last about a week because after this time there may be a disturbance in the temperature circadian rhythm and a significant CK accumulation Significance. Multi-day speed-power training induced a progressive reduction in resting skin temperature and an elevation in CK levels. It also altered the circadian rhythm of the body skin temperature, which may indicate that after about 6 d of regular exercise, physiological deregulation may occur.
The attachment length in orificed hollow cathodes
Authors: Wordingham C J , Taunay P-Y C R , Choueiri E Y 
Published: November 2021

Abstract
A first-principles approach to obtain the attachment length within a hollow cathode with a constrictive orifice, and its scaling with internal cathode pressure, is developed. This parameter, defined herein as the plasma density decay length scale upstream of (away from) the cathode orifice, is critical because it controls the utilization of the hollow cathode insert and influences cathode life. A two-dimensional framework is developed from the ambipolar diffusion equation for the insert-region plasma. A closed-form solution for the plasma density is obtained using standard partial differential equation techniques by applying an approximate boundary condition at the cathode orifice plane. This approach also yields the attachment length and electron temperature without reliance on measured plasma property data or complex computational models. The predicted plasma density profile is validated against measurements from the NSTAR discharge cathode, and calculated electron temperatures and attachment lengths agree with published values. Nondimensionalization of the governing equations reveals that the solution depends almost exclusively on the neutral pressure-diameter product in the insert plasma region. Evaluation of analytical results over a wide range of input parameters yields scaling relations for the variation of the attachment length and electron temperature with the pressure-diameter product. For the range of orifice-to-insert diameter ratio studied, the influence of orifice size is shown to be small except through its effect on insert pressure, and the attachment length is shown to be proportional to the insert inner radius, suggesting high-pressure cathodes should be constructed with larger-diameter inserts.
Scalar and Dirac quasinormal modes of scalar-tensor-Gauss-Bonnet black holes *

Published: November 2021

Abstract
This study explores the scalar and Dirac quasinormal modes pertaining to a class of black hole solutions in the scalar-tensor-Gauss-Bonnet theory. The black hole metrics in question are novel analytic solutions recently derived in the extended version of the theory, which effectively follows at the level of the action of string theory. Owing to the existence of a nonlinear electromagnetic field, the black hole solution possesses a nonvanishing magnetic charge. In particular, the metric is capable of describing black holes with distinct characteristics by assuming different values of the ADM mass and the magnetic charge. This study investigates the scalar and Dirac perturbations in these black hole spacetimes; in particular, we focus on two different types of solutions, based on distinct horizon structures. The properties of the complex frequencies of the obtained dissipative oscillations are investigated, and the stability of the metric is subsequently addressed. We also elaborate on the possible implications of this study.
Features of a negative ionization wave development preceding the full breakdown in a long capillary tube wrapped with a continuous or fine-sectioned grounded electrode
Authors: Akishev Yu S , Karalnik V B , Petryakov A V 
Published: November 2021

Abstract
The experimental results on the study of negative ionization wave propagating along a long capillary tube are presented. The ionization wave was initiated by high-voltage pulse of negative polarity. The propagation of this surface ionization wave precedes and influences the establishment of complete electric breakdown within the tube. The spreading of this wave is accompanied by the surface charge deposition. The usage of the fine-sectioned outer electrode allows one to find out the general features of a negative ionization wave. The main of them is the tight correlation between local currents determining the formation of local surface charge and visual discharge images taken by the fast camera characterizing the pace of the ionization wave propagation.

Authors: Kozlov B A , Makhanko D S 
Published: November 2021

Abstract
This article presents the results of “electrical wind” investigations in CO2–laser mixtures at superatmospheric (1–12 atm) pressures. It is established that for a fixed value of the unipolar corona discharge current, the gas flow velocity does not depend on the pressure, but is determined by the chemical composition of the working mixture. The maximum values of the “electrical wind” velocity are achieved in carbon dioxide and molecular nitrogen and their values are 3.2 and 2.9 ms−1. In typical laser mixtures CO2:N2:He = 1:1:1 – 1:1:3 the velocity of the “electrical wind ” are in the range from 2.5 to 1.5 ms−.
Formation of dense plasma on the surface of a stainless steel conductor in superstrong magnetic fields

Published: November 2021

Abstract
In experiments on the GIT-12 megaampere generator, the characteristics of conductors made of AISI 321 stainless steel were investigated in the microsecond regime of increasing superstrong magnetic fields. In this regime, a skin explosion of the conductor material takes place with the formation of a dense plasma and its expansion into the interelectrode gap of the vacuum transmission line. The values of the characteristic magnetic field B0 = 100 T are determined, above which there is the effect of nonlinear diffusion of the magnetic field into the conductor, and the critical magnetic field BCT ≅ 260 T, the excess of which leads to the formation of dense plasma on the surface of the massive conductor. A method is proposed for increasing the critical magnetic field on the surface of a conductor up to 1.5 times by choosing the optimal thickness of the conducting surface, and criteria for its determination are given. The effect of increasing the critical magnetic field on the surface of a two-layer sample and creating a pressure in the Mbar range until the moment of formation and expansion of explosion products of an inner conductor with high conductivity has been tested.

Published: November 2021

Abstract
This work is devoted to the study of the effect of the duration of ion nitriding by glow discharge on the physical and mechanical properties of tool steel with different initial structure. We used specimens of R6M5 tool steel with a coarse-grained structure obtained after annealing at a temperature of 850°C and with a fine-grained structure obtained after severe plastic deformation by torsion discharge. With an increase in the duration of ion nitriding, the thickness of the hardened layer and wear resistance increase. The combination of plastic deformation with ion nitriding by glow discharge increases the adsorption and diffusion rate of the saturating element due to the creation of a highly fragmented and disoriented fine-grained structure and contributed to reduction in processing time.

Authors: Lee M.J. , Ko B.R. , Ahn S. 
Published: November 2021

Abstract
A real-time Data Acquisition (DAQ) system for the CULTASK axion haloscope experiment was constructed and tested.
The CULTASK is an experiment to search for cosmic axions using resonant cavities,
to detect photons from axion conversion through the inverse Primakoff effect in a few GHz frequency range in a very high magnetic field
and at an ultra low temperature. The constructed DAQ system utilizes a Field Programmable Gate Array (FPGA) for data processing and Fast Fourier Transformation.
This design along with a custom Ethernet packet designed for real-time data transfer enables 100% DAQ efficiency,
which is the key feature compared with a commercial spectrum analyzer.
This DAQ system is optimally designed for RF signal detection in the axion experiment,
with 100 Hz frequency resolution and 500 kHz analysis window.
The noise level of the DAQ system averaged over 100,000 measurements is around -111.7 dBm.
From a pseudo-data analysis, an improvement of the signal-to-noise ratio due
to repeating and averaging the measurements using this real-time DAQ system was confirmed.
Application of groundwater modeling to predict the effectiveness of various peat dome restoration methods in Pulang Pisau District, Central Kalimantan Province

Published: November 2021

Abstract
A number of Indonesian Peat Hydrological Units (Kesatuan Hidrologis Gambut/KHG) have undergone severe degradation and require an effective restoration measure to increase their ecological, social, and economic function. A peat dome located in Garung village, Pulang Pisau District, Central Kalimantan Province, was selected in this research. It aimed to apply the mathematical modeling to predict the effect of various restoration methods on the sustainability of ecological functions of peak dome in this area and reveal the advantage and disadvantages of each specified method. The groundwater model was performed in this research to simulate the influence of four different restoration methods on the groundwater level of the peak dome. The water budget and the hydraulic conductivity of groundwater assigned in the modeling were derived from the previous research done in the other village within the same Peat Hydrological Units. Meanwhile, the soil property data and the other data related to groundwater and canal properties were obtained from the field measurement at the location during the rainy season. The result of modeling indicates that the restoration method employing a combination of canal backfilling and revegetation affects the most effectively the rising groundwater level of peat dome in the model domain, followed by the individual canal backfilling and canal blocking methods, respectively. The modeling approach enables us to prove the outcome of each applied restoration method toward the area of peak dome having groundwater level lower than 40 cm. In order to be able to apply this model in the other peatland area, a model validation utilizing the field measurement of hydraulic conductivity, groundwater level, and the canal water level is necessary to be carried out throughout the year, particularly during the dry season.

Published: November 2021

Abstract
The water quality of the Sunter River in Jakarta was classified as heavily polluted due to activities around the river, both domestic and non-domestic. As one of the environmental parameters for water quality, the presence of Escherichia coli (E. coli) is normally found any natural environment, and under certain conditions it can become resistant to antimicrobials due to genetic mutations. The mutated E. coli produces Extended Spectrum Beta-Lactamase (ESBL) enzymes and has a higher survival ability in antibiotic-contaminated river water, thus potentially endangering public health. This study was aimed to evaluate the effect of environmental factors on the abundance of ESBL producing E. coli and their resistance to antibiotic cefotaxime. Sampling was conducted in six locations representing the upstreams and the downstreams of Sunter River, following the Global Surveillance guidelines. E. coli strains were isolated using Tryptone Bile X-glucuronide (TBX) agar medium (with and without the addition of cefotaxime 4μg/ml) and the antibiotic sensitivity test of ESBL E. coli was conducted by performing a double-disk test. The results showed that the highest average abundance of ESBL E. coli was found in the sample taken from Sindang Station (904.24 x 104 colony per unit (CFU) / 100 mL) and the lowest was from Sunter Station (1,58 x 104 CFU / 100 mL). The results of the Bivariate Pearson correlation analysis showed that temperature, pH, and salinity were negatively correlated with the abundance of ESBL-producing E. coli bacteria.
