ABSTRACT
The central regions of galaxies harbouring active galactic nuclei (AGNs) can be quite complex, especially at high activity, presenting, besides variability, a variety of phenomena related, e.g. to ionization/excitation mechanisms. A detailed study is necessary in order to understand better those objects. For that reason, we performed a multiwavelength analysis of the nuclear region of the nearby Seyfert galaxy NGC 7314, using an optical data cube obtained with the Integral Field Unit from the Gemini Multi-Object Spectrograph, together with Hubble Space Telescope images, X-ray data from the XMM–Newton and the Nuclear Spectroscopic Telescope Array and radio data from Atacama Large Millimeter/Submillimeter Array. The goals were to study the nuclear and circumnuclear emission, the emission of the AGN and the gas kinematics. The optical spectrum shows the emission of a Seyfert nucleus, with broad components in the H α and H β emission lines, characterising a type 1 AGN, with a spectrum rich in coronal emission lines. The spatial morphology of the [O iii] λ5007 suggests the presence of an ionization cone, west of the nucleus, meanwhile the east cone seems to be obscured by dust. An extended [Fe vii] λ6087 emission was also detected, which could be possibly explained by a scenario involving photoionization + shocks mechanisms. X-rays analyses showed that there are variations in the flux; however, we did not detect any variations in the column density along the line of sight. Its variability may be a consequence of changes in the AGN accretion rate.
Fundamental properties of red giants from Kepler and Gaia DR3 data: diagnostic potential of the mass–metallicity diagram
Authors: Yıldız M 
Published: November 2022

ABSTRACT
For solar-like oscillators, the asteroseismic relations connect the stellar mean density and surface gravity to observable properties of the oscillations. Since the space missions CoRoT and Kepler, the asteroseismic relations have been massively employed out of their theoretical domain of validity, that is the main-sequence solar-type stars, in particular for red giant stars. However, despite a surprisingly good performance of the asteroseismic relation with red giant stars, they are biased and attempts to parametrize the departure of the relations for evolved stars have been the subject of many recent efforts. In this study, we propose a new parametrization of the asteroseismic relations for red giants of radii up to ${\sim } 50\, \mathrm{R}_\odot$, based on a calibration performed with Gaia parallax data. We find that the asteroseismic scaling relations depend on metallicity and effective temperature. For this solution, we obtain a parallax offset of about −0.026 ± 0.001 mas, and radius ranges from 3.8 to 53.2 R⊙. Most stars have masses that range from 0.9 to 1.7 M⊙, with the star count peaking around 1.2 M⊙. We also use data of the eclipsing binaries with solar-like oscillating components for calibration and discuss the diagnostic potential of the mass–metallicity diagram for our understanding of the evolution of red giants and the chemodynamics of the Galactic disc. Using this diagram, we identify stars that lost and gained mass and estimate the minimum change in mass.
[O i] 6300 Å emission as a probe of external photoevaporation of protoplanetary discs
Authors: Ballabio Giulia , Haworth Thomas J , Henney W J 
Published: November 2022

ABSTRACT
We study the utility of the [O i] 6300 Å forbidden line for identifying and interpreting externally driven photoevaporative winds in different environments and at a range of distances. Thermally excited [O i] 6300 Å is a well-known tracer of inner disc winds, so any external contribution needs to be distinguishable. In external winds, the line is not thermally excited and instead results from the dissociation of OH, and we study how the line luminosity resulting from that process scales with the disc/environmental parameters. We find that the line luminosity increases dramatically with FUV radiation field strength above around 5000 G0. The predicted luminosities from our models are consistent with measurements of the line luminosity of proplyds in the Orion Nebula Cluster. The high luminosity in strong UV environments alone may act as a diagnostic, but a rise in the [O i]-to-accretion luminosity ratio is predicted to better separate the two contributions. This could provide a means of identifying external photoevaporation in distant clusters where the proplyd morphology of evaporating discs cannot be spatially resolved.

Objectives:
To explore trends in demographic characteristics of scleral lens (SL) practitioners and primary indications for SL fitting over 5 years.

Methods:
An online survey similar to the 2015 Scleral Lenses in Current Ophthalmic Practice Evaluation (SCOPE) study was designed and administered from November 8, 2019, through March 31, 2020, to attendees at two international contact lens meetings, members of the Scleral Lens Education Society, and participants in the 2015 SCOPE study. Practitioners reporting at least five completed SL fits were included in the analysis.

Results:
Of 922 respondents, 777 had fit at least five SLs: 63% from the United States (59 other countries were represented), findings similar to the 2015 survey, in which 799 respondents (72%) were US-based and 49 from other countries. Most practitioners were in community practice (76%) than academic practice (24%). In 2015, 64% were in community practice and 36% in academic practice. A median of 84% of SLs were fit for corneal irregularity, 10% for ocular surface disease, and 2% for uncomplicated refractive error. In comparison, the 2015 indications were 74%, 16%, and 10%, respectively. The median number of fits completed per practitioner was 100 (range, 5–10,000; mean [SD] 284 [717]; n=752). In 2015, the median was 36 (range, 5–3,600; mean [SD] 125 [299]; n=678).

Conclusions:
The number of experienced SL practitioners is increasing, as is international representation. Most practitioners practice in community rather than academic settings. SLs continue to be primarily prescribed for corneal irregularity and are rarely used solely for correction of refractive error.

ABSTRACTRecurrent disease outbreaks caused by different viruses, including the novel respiratory virus SARS-CoV-2, are challenging our society at a global scale; so better and handier virus detection methods would enable a faster response. Here, we present a novel nucleic acid detection strategy based on CRISPR-Cas9, whose mode of action relies on strand displacement rather than on collateral catalysis, using theStreptococcus pyogenesCas9 nuclease. Given a pre-amplification process, a suitable molecular beacon interacts with the ternary CRISPR complex upon targeting to produce a fluorescent signal. We show that SARS-CoV-2 DNA amplicons generated from patient samples can be detected with CRISPR-Cas9. Moreover, we show that CRISPR-Cas9 allows the simultaneous detection of different DNA amplicons with the same nuclease, either to detect different SARS-CoV-2 regions or different respiratory viruses. Collectively, this CRISPR-Cas9 R-loop usage for molecular beacon opening (COLUMBO) platform allows a multiplexed detection in a single tube, complements the existing CRISPR-based methods, and displays diagnostic potential.

AbstractMagnetic Particle Imaging (MPI) is a noninvasive imaging modality that exploits the saturation properties of superparamagnetic iron oxide particles (SPIOs). A major thrust of MPI research aims to sharpen the magnetic resolution of biocompatible SPIOs, which will be crucial for affordable and safe clinical translation. We recently reported on a new class of MPI tracers —called superferromagnetic iron oxide nanoparticles (SFMIOs) — which offer much sharper magnetic saturation curves. SFMIOs experimentally demonstrate 10-fold improvement inbothresolution and sensitivity. However, superferromagnetism is a relatively unexplored branch of physics and the nanoscale physics and dynamics of SFMIOs remain a mystery. Here we show experimentally that chaining of SPIOs can explain SFMIO’s boost in SNR and resolution. We show how concentration, viscosity, transmit amplitude, and pre-polarization time can all affect SPIO chain formation and SFMIO behavior. These experiments will inform strategies on SFMIO chemical synthesis as well as SFMIO data acquisition pulse sequences.

AbstractCartilaginous fishes are renowned for a keen sense of smell, a reputation based on behavioral observations and supported by the presence of large and morphologically complex olfactory organs. At the molecular level, genes belonging to the four families coding for most olfactory receptors in other vertebrates have been identified in a chimera and a shark, but it was unknown whether they actually code for olfactory receptors in these species. Here we describe the evolutionary dynamics of these gene families in cartilaginous fishes using genomes of a chimera, a skate, a sawfish and eight sharks. The number of putative OR, TAAR and V1R/ORA receptors is very low and stable whereas the number of putative V2R/OlfC receptors is higher and much more dynamic. In the catsharkScyliorhinus canicula, we show that many V2R/OlfC receptors are expressed in the olfactory epithelium in the sparsely distributed pattern characteristic for olfactory receptors. In contrast, the other three vertebrate olfactory receptor families are either not expressed (OR) or only represented with a single receptor (V1R/ORA and TAAR). The complete overlap of markers of microvillous olfactory sensory neurons with panneuronal marker HuC in the olfactory organ suggests the same cell type specificity of V2R/OlfC expression as for bony fishes, i.e. in microvillous neurons. The relatively low number of olfactory receptors in cartilaginous fishes compared to bony fishes could be the result of an ancient and constant selection in favor of a high olfactory sensitivity at the expense of a high discrimination capability.
Novel approach to stability analysis of DC drive with parameter uncertainty and perturbation in feedback system
Authors: Gopi Pasala 
Published: November 2022

Purpose
The purpose of this study is to analyze direct current (DC) drive stability, including parameter uncertainty and perturbation in the feedback loop, by computing disk margins.

Design/methodology/approach
Although the closed-loop stability analysis of a DC drive has been presented well in the referenced papers, the effect of parameter uncertainty and perturbation in the feedback loop has not yet been discussed well. In this study, the conventional and disk-based stability margins were measured and compared for the nominal parameters of the DC drive. Subsequently, the smallest disk-based margins that destabilize the feedback loop for a given perturbation are computed and compared with normal disk margins.

Findings
The disk-based margin offered by the DC drive controlled by the JAYA-PID controller is disk gain margins (DGM) = 8.41 dB and disk phase margin (DPM) = 48.410 and the smallest disk-based margin offered is DGM = 1.51 dB and DPM = 9.950. In addition, the effect of the modeled uncertainty on the disk stability margins was analyzed, and it was observed that the maximum allowable parameter uncertainty with the JAYA controller was 73% of its nominal parameters. The simulation results were validated using an experimental testbed.

Unveiling the impact of YouTube advertising on the cognitive attitude of Indian millennials
Authors: Anubha Anubha , Narang Daviender , Sharma Himanshu 
Published: November 2022

Purpose
YouTube (YT) has become a trend among millennials, and thus, marketers are trying to harness the power of it to communicate with them. Global marketers need to understand the mechanism of communicating via YT advertising (YTAD), especially in India that consists of 440 million millennials to re-strategize their YT communications. Consequently, this study aims to examine the influence of YTAD on the cognitive attitude, namely, brand awareness (BA) and brand knowledge (BK) of Indian millennials. The study also tests the moderating impacts of gender, device used for YT watching (DEYTW), duration and frequency of YT watching (DUYTW and FEYTW) on BA and BK.

Design/methodology/approach
Generalized linear model – analysis of variance has been used to investigate the proposed relationships in the study. Responses of 294 Indian millennials who watch YTAD regularly have been used for the final analysis. Moderating effects were also tested using Bonferroni pairwise comparisons.

Findings
The results revealed that YTAD significantly improves the cognitive attitude (BA and BK). However, gender was not found to have any moderating effect in the relationship of YTAD with BA, whereas moderating effects of gender were observed in the relationship of YTAD with BK. Furthermore, other moderators including DEYTW, DUYTW and FEYTW were found to have significant moderating impacts in the above-mentioned relationships.

Practical implications
In a country like India, comprising the largest millennial population of the world who spends a significant portion of their time in watching YT, it becomes crucial for global marketers to understand how the cognitive attitude (i.e. BA and BK) of millennials improves by watching YT advertisements. As it will help them in strategizing their communications on YT to get favourable consumers’ responses like purchase intention and actual purchase that may happen only when people have favourable cognitive attitude towards advertised brands.

Originality/value
The study offers new perspective to the field of communication by investigating the impact of YTAD on the cognitive attitude (i.e. BA and BK) of Indian millennials.
Contemporary spiritual seeking: understanding information interactions in contemplation and spirituality
Authors: Nangia Pranay , Ruthven Ian 
Published: November 2022

PurposeDiscussions in contemporary spirituality frequently highlight a phenomenon of spiritual seeking; moreover, people often describe their spiritual journeys in terms of a search. This paper takes a closer look at this metaphor by presenting a study that analysed spiritual seeking and its informational features in contemporary non-institutionalised settings.Design/methodology/approachIn this study, the authors conducted semi-structured interviews with thirteen spiritual teachers and speakers who were asked questions about spiritual seeking in contemporary non-institutionalised spirituality.FindingsThe authors' participants explained that contemporary spiritual seekers sought spiritual information as a result of affective, developmental and metaphysical concerns. Moreover, their analysis indicated that spiritual information-seeking behaviour incorporated practices such as prayer, yoga and meditation, and contemporary spiritual information interactions were facilitated through spiritual retreats, meditation classes, yoga classes and online social platforms.Research limitations/implicationsSince the authors focused on spiritual seeking in contemporary non-institutionalised settings, their findings cannot exhaustively represent all spiritual pursuits in contemporary society. Their study (1) identifies the informational features of contemporary spiritual seeking, (2) explains spiritual seeking as an activity that may theoretically reside within a broader framework of profound information interactions and (3) helps theorise the concept of qualitative profundity in information science research.Originality/valueThis study provides an intuitive contextual approach for undertaking information research in under-explored domains such as contemplation and spirituality.

Authors: McBee-Black Kerri 
Published: November 2022

PurposeThis study aimed to gain an in-depth and contextualized understanding of what impacted Scheier's commitment to addressing the apparel challenges of people with disabilities (PWDs) and how moral duty may have played a role in developing the adaptive design innovations used in the first-of-its-kind adaptive children's wear line.Design/methodology/approachTo achieve this goal, the study used the duty orientation (DO) theory and the social model of disability (SMD) theory to conduct a case study investigating Mindy Scheier's commitment to addressing the apparel challenges facing PWDs.FindingsThe result of the case study revealed three dominant themes that aligned with the DO theory: (a) duty to all PWDs, (b) duty to sacrifice and fight against all odds and (c) duty to solve the apparel challenges facing PWDs. Using the DO and the SMD theories, the themes illustrated how moral duty impacted Scheier's sacrifice and feeling of personal responsibility to address and solve the apparel challenges facing all PWDs.Originality/valueThis study demonstrated how the DO theory contextualized the launch of adaptive apparel into the mainstream fashion industry and how the apparel industry seems to have transitioned from a medical model of disability approach to an SMD to address the apparel needs of PWDs.

Heuristics in the wild: exploring fund manager decisions through the COVID pandemic
Authors: Gilcher Daniel 
Published: November 2022

Purpose
This paper aims to provide a novel explorative perspective on fund managers’ decisions under uncertainty. The current COVID pandemic is used as a unique reference frame to study how heuristics are used in institutional financial practice.

Design/methodology/approach
This study follows a grounded theory approach. A total of 282 diverse publications between October 2019 and October 2020 for 20 German mutual funds are qualitatively analyzed. A theory of adaptive heuristics for fund managers is developed.

Findings
Fund managers adapt their heuristics during a crisis and this adaptive process flows through three stages. Increasing complexity in the environment leads to the adaption of simplest heuristics around investment decisions. Three distinct stages of adaption: precrisis, uncertainty and stabilization emerge from the data.

Research limitations/implications
This study’s data is based on publicly available information. There might be a discrepancy between publicly stated and internal reasoning.

Practical implications
Money managers can use the provided framework to assess their decision-making in crises. The developed adaptive processes of heuristics can assist capital allocators who choose and rate fund managers. Policymakers and regulators can learn about the aspects of investor decisions that their actions and communication address. Teaching can use this study to exemplify the nature of financial markets as adaptive systems rather than static structures.

Originality/value
To the best of the author’s/authors’ knowledge, this study is the first to systematically explore the heuristics of professional money managers because they navigate a large-scale exogenous crisis.

Authors: Pieper Brandy , Krsmanovic Masha 
Published: November 2022

Purpose
The purpose of this study is to examine whether implicit bias exists within the graduate admissions process at a large public research university in the Southeast United States. Additionally, this research sought to identify the type of strategies graduate faculty in the USA use to assess their implicit bias and the support they may need to better recognize and gauge implicit bias during the graduate application review process.

Design/methodology/approach
This study used the use of a qualitative, phenomenological research design by conducting individual interviews with graduate faculty members that serve on admissions committees.

Findings
The findings revealed six themes in relation to the purpose of the study – bias recognition, faculty perceptions of their own bias, faculty perceptions on the bias of others, strategies for the application review process, admission committee safeguards and the need for implicit bias training.

Originality/value
The study outcomes are discussed in relation to the prior research and literature on this phenomenon. Additionally, the study presents research and practical implications, including actionable strategies for how its results can be practically applied.
