Abstract
In this study, we explore whether Zoom is a viable method for collecting data for sociophonetic research, focusing on vocalic analysis. We investigate whether recordings collected through Zoom yield different acoustic measurements than recordings collected through in-person recording equipment, for the exact same speech. We analyze vowel formant data from 18 speakers who recorded Zoom conversations at the same time as they recorded themselves with portable recording equipment. We find that, overall, Zoom recordings yield lower raw F1 values and higher F2 values than recording equipment. We also tested whether normalization affects discrepancies between recording methods and found that while discrepancies still appear after normalizing with the Watt and Fabricius modified method, Lobanov normalization largely minimizes discrepancies between recording methods. Discrepancies are also mitigated with a Zoom recording setup that involves the speaker wearing headphones and recording with an external microphone.
Lessons learned: the long view

Abstract
The COVID-19 pandemic has substantially altered the fabric of life around the globe, raising crucial questions about the nature of language usage in person and online. But as researchers embark on new studies (or continuations of pre-COVID research), just as essential are considerations of what our responsibilities as researchers are to our participants now. In this article, we share our reflections upon the experience of conducting research in two different post-disaster contexts: after Hurricane Katrina in New Orleans, Louisiana, and after the Christchurch earthquakes in New Zealand. We describe the issues faced by researchers and participants alike in these locales and we recount the decisions that we made, as many of the same decision processes are being faced by researchers currently navigating data collection due to COVID-19 and its aftermath. These decisions are of course contextually dependent, though our examples draw from two very different situations, comparing and contrasting how various forces, timelines, and regionally specific issues may come into play for researchers in a context of upheaval. In this “long view” essay, we provide a retrospective account of practical tips and ethical considerations for researchers embarking on a similar track.
Simulation of Gaussian random field in a ball
Authors: Kolyukhin Dmitriy , Minakov Alexander 
Published: February 2022

Abstract
We address the problem of statistical simulation of a scalar real Gaussian random field inside the unit 3D ball. Two different methods are studied: (i) the method based on the known homogeneous isotropic power spectrum developed by Meschede and Romanowicz
[M. Meschede and B. Romanowicz,
Non-stationary spherical random media and their effect on long-period mantle waves,
Geophys. J. Int. 203 2015, 1605–1625]
and (ii) the method based on known radial and angular covariance functions suggested in this work. The first approach allows the extension of the simulation technique to the inhomogeneous or anisotropic case. However, the disadvantage of this approach is the lack of accurate statistical characterization of the results. The accuracy of considered methods is illustrated by numerical tests, including a comparison of the estimated and analytical covariance functions. These methods can be used in many applications in geophysics, geodynamics, or planetary science where the objective is to construct spatial realizations of 3D random fields based on a statistical analysis of observations collected on the sphere or within a spherical region.

Abstract
Since late 2019, the beginning of coronavirus disease 2019 (COVID-19) pandemic, transmission dynamics models have achieved great development and were widely used in predicting and policy making. Here, we provided an introduction to the history of disease transmission, summarized transmission dynamics models into three main types: compartment extension, parameter extension and population-stratified extension models, highlight the key contribution of transmission dynamics models in COVID-19 pandemic: estimating epidemiological parameters, predicting the future trend, evaluating the effectiveness of control measures and exploring different possibilities/scenarios. Finally, we pointed out the limitations and challenges lie ahead of transmission dynamics models.

Abstract
Naturwissenschaftliche Informationen, insbesondere die chemische Zusammensetzung der Objekte, können Hinweise auf die Hintergründe der Objektherstellung liefern, die der alleinigen kunsthistorischen Begutachtung verborgen blieben. Es können nicht nur Fragen nach dem Prozess, Zeitpunkt und Ort der Herstellung beantwortet werden. Die chemische Analyse gibt auch Hinweise auf Ereignisse und Veränderungen, die erst nach der Fertigstellung des Objektes erfolgten. So werden Alterungsphänomene oder historische Überarbeitungen und Restaurierungen aufgedeckt, aber auch Konservierungsstrategien zur Erhaltung der Kunstwerke unterstützt. Durch den technologischen Fortschritt im Bereich der röntgenanalytischen Methoden, die berührungsfrei, ohne Probennahme und ohne Schädigung für das Untersuchungsobjekt arbeiten, erschließen sich dem Analytiker erstmalig Möglichkeiten, auch sehr wertvolle und fragile Objekte zerstörungsfrei zu untersuchen.
Performance demonstration for humanitarian demining
Authors: Müller Christina , Scharmach Martina , Gaal Mate , Guelle Dieter , Lewis Adam , Sieber Alois 
Published: February 2022

Abstract
Because the demining process is always connected with a danger for human beings, it is necessary to make sure the proper functioning of mine searching equipment in detecting mines. Detecting a hidden target by penetrating physical interaction of rays or waves is similar to non-destructive testing. The non-destructive testing profession developed procedures to check the reliability of testing. These procedures, like the performance demonstration where the successful detections are statistically evaluated against false call rates and their implementation in an industrial standard (ASME section XI appendix VIII) are used as a template. A first adoption to demining was accomplished in the prescription for blind trials in the CEN workshop agreement CWA 14747: 2003 for test and evaluation of metal detectors. Within an ITEP project a number of blind trials were carried out to learn about the necessary statistical basis of those trials to achieve true, reproducible and repeatable results to give guidance for the selection and improvement of metal detectors. The special focus in this first investigation was on the influence of the human factor due to the different degree of experience of the operators and the influence of the soil.
Ways to control the inaccuracy of old and new results of measurements of the elastic properties of metallic elements
Authors: Buch Alfred 
Published: February 2022

Abstract
The older and newer results of measurements of elastic properties often show a large scatter of values, and not always do new tests result in more accurate values. The fact that for many metals there is often a need of new tests is not only associated with better test methods and machines, but also with the dissatisfaction with the older results, because they present different results for the same metals. Sometimes the handbook editors cannot decide if a new test presents a better value, and publish different results, leaving the reader with the option to decide, which value seems to be better. Of course, this cannot satisfy the researchers using the handbooks and thus, the present contribution shows some ways to select accurate values.
Nonlocal effects in temporal metamaterials
Authors: Rizza Carlo , Castaldi Giuseppe , Galdi Vincenzo 
Published: February 2022

Abstract
Nonlocality is a fundamental concept in photonics. For instance, nonlocal wave-matter interactions in spatially modulated metamaterials enable novel effects, such as giant electromagnetic chirality, artificial magnetism, and negative refraction. Here, we investigate the effects induced by spatial nonlocality in temporal metamaterials, i.e., media with a dielectric permittivity rapidly modulated in time. Via a rigorous multiscale approach, we introduce a general and compact formalism for the nonlocal effective medium theory of temporally periodic metamaterials. In particular, we study two scenarios: (i) a periodic temporal modulation, and (ii) a temporal boundary where the permittivity is abruptly changed in time and subject to periodic modulation. We show that these configurations can give rise to peculiar nonlocal effects, and we highlight the similarities and differences with respect to the spatial-metamaterial counterparts. Interestingly, by tailoring the effective boundary wave-matter interactions, we also identify an intriguing configuration for which a temporal metamaterial can perform the first-order derivative of an incident wavepacket. Our theoretical results, backed by full-wave numerical simulations, introduce key physical ingredients that may pave the way for novel applications. By fully exploiting the time-reversal symmetry breaking, nonlocal temporal metamaterials promise a great potential for efficient, tunable optical computing devices.
Femtosecond imaging of spatial deformation of surface plasmon polariton wave packet during resonant interaction with nanocavity
Authors: Ichiji Naoki , Otake Yuka , Kubo Atsushi 
Published: February 2022

Abstract
The spatiotemporal dynamics of a surface plasmon polariton (SPP) wave packet (WP) that interacts with a plasmonic nanocavity on a metal surface are investigated via femtosecond time-resolved two-photon fluorescence microscopy and numerical calculations. The nanocavity, which consists of a metal–insulator–metal (MIM) laminar structure (longitudinal length: ∼100 nm), behaves as a subwavelength meta-atom possessing discretized eigenenergies. When a chirp-induced femto-second SPP WP is incident on the nanocavity, only the spectral component matching a particular eigenenergy is transmitted to continue propagation on the metal surface. This spectral clipping induces a spatial peak shift in the WP. The shift can be controlled by tuning the eigenenergy or chirp.
Vortex radiation from a single emitter in a chiral plasmonic nanocavity

Published: February 2022

Abstract
Manipulating single emitter radiation is essential for quantum information science. Significant progress has been made in enhancing the radiation efficiency and directivity by coupling quantum emitters with microcavities and plasmonic antennas. However, there has been a great challenge to generate complex radiation patterns such as vortex beam from a single emitter. Here, we report a chiral plasmonic nanocavity, which provides a strong local chiral vacuum field at an exceptional point. We show that a single linear dipole emitter embedded in the nanocavity will radiate to vortex beam via anomalous spontaneous emission with a Purcell enhancement factor up to ∼1000. Our scheme provides a new field manipulation method for chiral quantum optics and vortex lasers at the nanoscale.

Abstract
Novel results on conformable Bessel functions are proposed in this study. We complete this study by proposing and proving certain properties of the Bessel functions of first order involving their conformable derivatives or their zeros. We also establish the orthogonality of such functions in the interval [0,1]. This study is essential due to the importance of these functions while modeling various physical and natural phenomena.

Published: February 2022

AbstractMetal oxides are ideal for the fabrication of gas sensors: they are sensitive to many gases while allowing the device to be simple, tiny, and inexpensive. Nonetheless, their lack of selectivity remains a limitation. In order to achieve good selectivity in applications with many possible interfering gases, the sensors are inserted into anelectronic nosethat combines the signals from nonselective sensors and analyzes them with multivariate statistical algorithms in order to obtain selectivity. This review analyzes the scientific articles published in the last decade regarding electronic noses based on metal oxide nanowires. After a general introduction, Section 2 discusses the issues related to poor intrinsic selectivity. Section 3 briefly reviews the main algorithms that have hitherto been used and the results they can provide. Section 4 classifies the recent literature into fundamental research, agrifood, health, security. In Section 5, the literature is analyzed regarding the metal oxides, the surface decoration nanoparticles, the features that differentiate the sensors in a given array, the application for which the device was developed, the algorithm used, and the type of information obtained. Section 6 concludes by discussing the present state and points out the requirements for their use in real-world applications.
Pitting corrosion induced on high-strength high carbon steel wire in high alkaline deaerated chloride electrolyte
Authors: Lee Siaw Foon , García Jose Fullea , Yap Seong Shan , Hui David 
Published: February 2022

Abstract
Electrochemical response causing pitting corrosion of high-strength high carbon steel wire in deaerated electrolyte at pH 13.4 due to different chloride ion (Cl−) concentrations was investigated using open circuit potential, cyclic potentiodynamic polarization, and anodic potentiostatic application (APA) within the passive zone. Results showed that the higher the Cl− concentration, the more negative the corrosion potential becomes. In the high alkaline pH 13.4 without the presence of free oxygen gas the Cl− concentration could reach up to 1 M not showing pitting potential. An inverse relationship between anodic potentials (APs) and Cl− concentrations was found and the rate of corrosion within passive period was almost a constant, not influenced by the Cl− concentrations. Faraday´s law failed to predict the mass loss when active pitting corrosion occurred. Green rust and hydrogen gas were observed during active pitting corrosion under APA. Pitting corrosion mechanism in the deaerated high alkaline electrolyte was then proposed. This work deduces that in the deaerated electrolyte at pH 13.4 with the presence of Cl−, it is essential to apply the APs within the safety margin on the high-strength high carbon steel wire to avoid active pitting corrosion and hydrogen embrittlement.
„aber ich finds ein bisschen HEIkel eben,“
Authors: Hauser Stefan , Kreuz Judith 
Published: February 2022

AbstractIn a growing number of schools, class councils are a regularly practiced interactional format to support pupils’ participation in decision making processes as well as the development of social competence. Whether class councils should also be used to resolve social conflicts, however, is controversial. While the class council is viewed as a suitable opportunity to discuss the pupils’ diverging views in many studies, others are highly critical of this idea, citing the potential effects of conflicting requirements. In this article, we take a conversation analytical approach to how the rhetorical practices and social competence of 9- to 15-year-old pupils and the teacher involvement affect the ways in which conflicts are resolved. Focusing on practices of addressing and social positioning, we analyse how the complex requirements of collective conflict resolution are interactionally dealt with during class councils. Our analysis shows that, on a structural level, the participants are confronted with three facets of processing and resolving social conflicts: reconstruction, resolution and organization. Against the backdrop of these core categories, we propose several practical considerations aimed at increasing teachers’ awareness of the interactional requirements of collaborative conflict resolution.
Crystal structure of a hexacationic Ag(I)-pillarplex-dodecyl-diammonium pseudo-rotaxane as terephthalate salt
Authors: Heidecker Alexandra A. , Bohn Moritz , Pöthig Alexander 
Published: February 2022

Abstract
A new pseudo-rotaxane, consisting of a tubular, organometallic Ag-pillarplex ring and dodecyldiammonium axle component, is introduced and investigated towards potential non-covalent interactions by Full Interaction Maps (FIMs). FIMs predict regions of probable supramolecular interactions solely at the organic ligands, namely the rim and the aromatic rings of the pillarplex. The results were compared to structural parameters experimentally obtained by single-crystal X-ray diffraction. The pseudo-rotaxane was crystallized as a hydrated terephthalate salt, and the molecular and the crystal structure are discussed. The experimentally observed interactions are quantified using Hirshfeld surface analysis. In contrast to the FIMs prediction, four different interaction modes can be experimentally observed in the solid-state: encapsulation of a guest molecule, hydrogen bonding, π- and metal interactions.
Temporal Context Modulates Encoding and Retrieval of Overlapping Events
Authors: Smith Devyn E. , Moore Isabelle L. , Long Nicole M. 
Published: March 2022

Overlap between events can lead to interference because of a trade-off between encoding the present event and retrieving the past event. Temporal context information, “when” something occurred, a defining feature of episodic memory, can cue retrieval of a past event. However, the influence of temporal overlap, or proximity in time, on the mechanisms of interference is unclear. Here, by identifying brain states using scalp EEG from male and female human subjects, we show the extent to which temporal overlap promotes interference and induces retrieval. In this experiment, subjects were explicitly directed to either encode the present event or retrieve a past, overlapping event while perceptual input was held constant. We find that the degree of temporal overlap between events leads to selective interference. Specifically, greater temporal overlap between two events leads to impaired memory for the past event selectively when the top-down goal is to encode the present event. Using pattern classification analyses to measure neural evidence for a retrieval state, we find that greater temporal overlap leads to automatic retrieval of a past event, independent of top-down goals. Critically, the retrieval evidence we observe likely reflects a general retrieval mode, rather than retrieval success or effort. Collectively, our findings provide insight into the role of temporal overlap on interference and memory formation.SIGNIFICANCE STATEMENTWhen a present event overlaps with an event from the past, this leads to a trade-off between the tendency to encode the present event versus retrieve the past event. Here we show that, when two events are experienced nearby in time, the memory system is biased toward a retrieval state and that subsequent memory for the past event is impaired. These findings suggest an influence of bottom-up temporal factors on both interference and the trade-off between memory states.
Perceptual Weighting of V1 Spikes Revealed by Optogenetic White Noise Stimulation
Authors: Day-Cooney Julian , Cone Jackson J. , Maunsell John H. R. 
Published: March 2022

During visually guided behaviors, mere hundreds of milliseconds can elapse between a sensory input and its associated behavioral response. How spikes occurring at different times are integrated to drive perception and action remains poorly understood. We delivered random trains of optogenetic stimulation (white noise) to excite inhibitory interneurons in V1 of mice of both sexes while they performed a visual detection task. We then performed a reverse correlation analysis on the optogenetic stimuli to generate a neuronal-behavioral kernel, an unbiased, temporally precise estimate of how suppression of V1 spiking at different moments around the onset of a visual stimulus affects detection of that stimulus. Electrophysiological recordings enabled us to capture the effects of optogenetic stimuli on V1 responsivity and revealed that the earliest stimulus-evoked spikes are preferentially weighted for guiding behavior. These data demonstrate that white noise optogenetic stimulation is a powerful tool for understanding how patterns of spiking in neuronal populations are decoded in generating perception and action.SIGNIFICANCE STATEMENTDuring visually guided actions, continuous chains of neurons connect our retinas to our motoneurons. To unravel circuit contributions to behavior, it is crucial to establish the relative functional position(s) that different neural structures occupy in processing and relaying the signals that support rapid, precise responses. To address this question, we randomly inhibited activity in mouse V1 throughout the stimulus-response cycle while the animals did many repetitions of a visual task. The period that led to impaired performance corresponded to the earliest stimulus-driven response in V1, with no effect of inhibition immediately before or during late stages of the stimulus-driven response. This approach offers experimenters a powerful method for uncovering the temporal weighting of spikes from stimulus to response.
Anthony Trollope’s Leap in the Dark
Authors: Vignola Michael 
Published: March 2022

Michael Vignola, “Anthony Trollope’s Leap in the Dark: The Temporality of Victorian Political Reform and Victorian Women’s Suffrage” (pp. 321–353)
Anthony Trollope’s Phineas Finn (1867; 1869) depicts the seminal expansion of democracy under the Second Reform Act, an event that had yet to conclude when he finished composing the novel. This unique circumstance gives rise in the novel to anticipations that await real-world contingencies to become legible. Phineas Finn’s thick particularities thus bring into focus the temporality of reform characterized by the indeterminacy encoded in the phrase “a leap in the dark.” Attention to the circulation of the phrase and its evocation in Phineas Finn reveals the centrality of women’s suffrage to the project of democratic reform, particularly in its promise to realign the boundaries of political and private life.
