3d $$ \mathcal{N} $$ = 3 generalized Giveon-Kutasov duality
Authors: Kubo Naotaka , Nii Keita 
Published: April 2022

Abstract
We generalize the Giveon-Kutasov duality for the 3d $$ \mathcal{N} $$
N
= 3 U(N)k,k+nN Chern-Simons matter gauge theory with F fundamental hypermultiplets by introducing SU(N) and U(1) Chern-Simons levels differently. We study the supersymmetric partition functions and the superconformal indices of the duality, which supports the validity of the duality proposal. From the duality, we can map out the low-energy phases: for example, confinement appears for F + k − N = −n = 1 or N = 2F = k = −n = 2. For F + k − N < 0, supersymmetry is spontaneously broken, which is in accord with the fact that the partition function vanishes. In some cases, the theory shows supersymmetry enhancement to 3d $$ \mathcal{N} $$
N
= 4. For k = 0, we comment on the magnetic description dual to the so-called “ugly” theory, where the usual decoupled sector is still interacting with others for n ≠ 0. We argue that the SU(N)0 “ugly-good” duality (which corresponds to the n → ∞ limit in our setup) is closely related to the S-duality of the 4d $$ \mathcal{N} $$
N
= 2 SU(N) superconformal gauge theory with 2N fundamental hypermultiplets. By reducing the number of flavors via real masses, we suggest possible ways to flow to the “bad” theories.

Abstract
Recently, hypoglycemic drugs belonging to sodium-glucose cotransporter 2 inhibitors (SGLT2i) have generated significant interest due to their clear cardiovascular benefits for heart failure with preserved ejection fraction (HFpEF) since there are no effective drugs that may improve clinical outcomes for these patients over a prolonged period. But, the underlying mechanisms remain unclear, particularly its effects on ferroptosis, a newly defined mechanism of iron-dependent non-apoptotic cell death during heart failure (HF). Here, with proteomics, we demonstrated that ferroptosis might be a key mechanism in a rat model of high-salt diet-induced HFpEF, characterized by iron overloading and lipid peroxidation, which was blocked following treatment with canagliflozin. Data are available via ProteomeXchange with identifier PXD029031. The ferroptosis was evaluated with the levels of acyl-CoA synthetase long-chain family member 4, glutathione peroxidase 4, ferritin heavy chain 1, transferrin receptor, Ferroportin 1, iron, glutathione, malondialdehyde, and 4-hydroxy-trans-2-nonenal. These findings highlight the fact that targeting ferroptosis may serve as a cardioprotective strategy for HFpEF prevention and suggest that canagliflozin may exert its cardiovascular benefits partly via its mitigation of ferroptosis.

AbstractThe way in which retirement is conceptualized and measured is likely to influence the research findings. The previous literature has addressed a wide range of elements related to the complex work-to-retirement process, such as early, late and partial retirement, statutory retirement, work disability and unemployment paths to retirement, or different types of bridge employment. However, conceptual clarity in terms of connections between the different elements is called for. We introduce a conceptual framework of the work-to-retirement process to guide its future measurement. Together with information on the statutory retirement age, the main elements of the framework are based on employment and pension receipt, acknowledging that these may overlap. The framework is flexible to the user, providing the possibility to add various specifications—e.g. of types of employment, types of pension receipt, unemployment, and being outside the labour force—depending on the study context and aims. The framework highlights the complexity of the work-to-retirement process, bringing forth its multifaceted, multiphased and multidirectional features. Accounting for such complexity in later-life labour market dynamics helps to elaborate what is actually addressed when investigating “retirement”. Our conceptual framework can be utilized to enhance well-defined, precise and comparable measurement of the work-to-retirement process in studies.
Generalized kings and single-elimination winners in random tournaments
Authors: Manurangsi Pasin , Suksompong Warut 
Published: April 2022

AbstractTournaments can be used to model a variety of practical scenarios including sports competitions and elections. A natural notion of strength of alternatives in a tournament is a generalized king: an alternative is said to be a k-king if it can reach every other alternative in the tournament via a directed path of length at most k. In this paper, we provide an almost complete characterization of the probability threshold such that all, a large number, or a small number of alternatives are k-kings with high probability in two random models. We show that, perhaps surprisingly, all changes in the threshold occur in the range of constant k, with the biggest change being between $$k=2$$

k
=
2

and $$k=3$$

k
=
3

. In addition, we establish an asymptotically tight bound on the probability threshold for which all alternatives are likely able to win a single-elimination tournament under some bracket.
Russellian Representationalism and the Stygian Hues
Authors: Sharp William A. 
Published: April 2022

AbstractRepresentationalism is today the leading physicalist theory of the phenomenal character of perceptual experience. And Russellian representationalism, which identifies contents with extensions, is the leading iteration of that theory. If there exist phenomenally distinct experiences as of the impossible, then these wouldprima facieserve as counterexamples to the theory. In order that they definitively serve as counterexamples, it needs to be that there is no plausible account of the experiences on which they decompose into constituent elements each of which is unproblematic from the perspective of the theory. The contention of this paper is that thestygian color experiences, afterimage-experiences as of maximally dark, hued surfaces, of Churchland (Churchland, Philosophical Psychology 18:527–560, 2005) serve as counterexamples to Russellian representationalism.
Tales of Multifunctionality: a Systematic Quantitative Literature Review of Boomerangs Used as Retouchers in Australian Aboriginal Cultures
Authors: Martellotta Eva Francesca , Brumm Adam , Langley Michelle C. 
Published: April 2022

AbstractBoomerangs are among the most recognisable elements of Australian Aboriginal technology. In the popular mindset, the prevailing image of these wooden artefacts is that of thrown implements that return to the thrower, principally used for hunting animals. However, boomerangs have a deep multipurpose role in Indigenous societies, with just a few examples of their known functions, including fighting, digging, and making music (i.e., “clap sticks”). Recently, yet another function for boomerangs has been proposed (Martellotta et al., 2021): the functional modification of lithic tools (i.e., retouching)—a form of use that is almost unknown among non-Aboriginal researchers. Here, we provide the first comprehensive review of evidence for the use of boomerangs as lithic retouching tools (percussors). A detailed lexical analysis demonstrates similarities between Palaeolithic bone retouchers used for the same purposes as the Australian hardwood boomerangs, thus confirming our traceological hypothesis and the power of using a multidisciplinary approach in investigating Australia’s deep past. This paper provides the foundation for discussions surrounding the multipurpose concept behind many Aboriginal tools by focusing on the most iconic item. We propose that, in future studies, the complex technological and functional features of boomerangs should take precedence over their famous “returning effect”.
Are Extended Reality Interventions Effective in Helping Autistic Children to Enhance Their Social Skills? A Systematic Review
Authors: Roberts Rebecca , Stacey James , Jenner Susannah , Maguire Eloise 
Published: April 2022

AbstractAutistic children’s social skills do not always align with those of their neurotypical peers and research suggests that this can negatively impact quality of life. This review aimed to assess the effectiveness of extended reality (XR) interventions in helping autistic children to enhance their social skills. Five electronic databases were systematically searched and seventeen studies were identified. The majority targeted social-emotional reciprocity and were of relatively low quality. There was insufficient evidence to determine whether effects were generalisable, sustained or important to autistic people. Research in this field is in its infancy and evidence of effectiveness should be viewed with caution. Future studies should aim for high-quality, theory-driven research, and involve autistic people to ensure meaningful outcomes.PROSPERO ID: CRD42021229442
Could wavefunctions simultaneously represent knowledge and reality?
Authors: Hance Jonte R. , Rarity John , Ladyman James 
Published: April 2022

AbstractIn discussion of the interpretation of quantum mechanics the terms ‘ontic’ and ‘epistemic’ are often used in the sense of pertaining to what exists, and pertaining to cognition or knowledge respectively. The terms are also often associated with the formal definitions given by Harrigan and Spekkens for the wavefunction in quantum mechanics to be $$\psi $$
ψ
-ontic or $$\psi $$
ψ
-epistemic in the context of the ontological models framework. The formal definitions are contradictories, so that the wavefunction can be either $$\psi $$
ψ
-epistemic or $$\psi $$
ψ
-ontic but not both. However, we argue, nothing about the informal ideas of epistemic and ontic interpretations rules out wavefunctions representing both reality and knowledge. The implications of the Pusey–Barrett–Rudolph theorem and many other issues may be rethought in the light of our analysis.

Abstract
Purpose
To evaluate if a web-based telemedicine system (the Glucoonline® system) is effective to improve glucose control in insulin-treated patients with type 1 and type 2 diabetes, as compared to standard of care.

Methods
This was a prospective, randomized, controlled trial, carried out at three tertiary referral centers for diabetes in Italy. Adults with insulin-treated type 1 and type 2 diabetes, inadequate glycemic control, and no severe diabetes-related complications and/or comorbidities were eligible for this study. Patients were randomized to either perform telemedicine-assisted (Group A) or standard (Group B) self-monitoring blood glucose (SMBG) for 6 months. In Group A, patients received prompt feedback about their blood glucose levels and therapy suggestions from the study staff via phone/SMS, when appropriate. In Group B, patients had no remote assistance from the study staff between planned visits.

Results
123 patients were included in the final analysis. After 6 months, patients achieved a significant reduction in HbA1c in Group A (−0.38%, p < 0.05) but not in Group B (+ 0.08%, p = 0.53). A significant difference in the percentage of patients with HbA1c < 7% between Group A and Group B was found after 3 months (28.6% vs 11.1%, p = 0.02). Also, fewer patients (p < 0.05) with HbA1c > 8.5% were found in Group A vs Group B, respectively, after both 3 months (14.3% vs 35.2%) and 6 months (21.8% vs 42.9%).

Conclusions
The use of the Glucoonline™ system resulted in improved metabolic control. Telemedicine services have potential to support diabetes self-management and provide the patients with remote, prompt assistance using affordable technological equipment.

Creating supply chain resilience during and post-COVID-19 outbreak: the organizational ambidexterity perspective
Authors: Ocicka Barbara , Mierzejewska Wioletta , Brzeziński Jakub 
Published: April 2022

AbstractThis study aims to investigate the significance of organizational ambidexterity (OA) in creating supply chain resilience (SCRES) during and after the COVID-19 pandemic. The methodological triangulation is applied in this study. A literature review, semi-structured online interviews and insights from open webinars serve as the sources of data. A framework, based on three pillars: validation, positioning and evaluation of business practices, is used for data analysis. The dependencies between OA activities and SCRES strategies are presented. The authors discuss their evolution during and in the post-pandemic period and outline the SCM trends in a strategic perspective. This paper investigates a pathway for closing the gap between OA theory and industry practice to create SCRES during and post-COVID-19 outbreak. This article starts the discussion on creating SCRES through OA. Future quantitative and qualitative research should explore the applicability of OA to enhance SCRES in a dynamic environment. Understanding the critical connection between exploitation and exploration practices and how OA influences SCRES provides valuable insight into the subject to supply chain managers supporting them in pursuing their roles successfully in the times of crisis. This study is focused on two concepts, OA and SCRES, of critical importance for how practitioners manage supply chains in the times of crisis. The resilience of supply chains to crises is crucial for the well-being of societies.
Wie, wann und warum nutzen Schüler*innen Lerngelegenheiten im Unterricht? Eine übergreifende Diskussion der Beiträge zum Thementeil
Authors: Vieluf Svenja 
Published: April 2022

ZusammenfassungWas und wie viel in der Schule gelernt wird, hängt nicht nur von der Gestaltung des Lernangebotes ab, sondern auch davon, ob und wie dieses von den Schüler*innen genutzt wird. Zudem kann die Art der Nutzung von Lerngelegenheiten auch den Unterrichtsverlauf mitprägen. Nutzung zu verstehen ist insofern zentral, um die Wirksamkeit von Unterricht erklären zu können. Der vorliegende Diskussionsbeitrag hat zum Ziel, vier quantitative Analysen von Nutzungsprozessen vor der theoretischen Folie der Angebots-Nutzungs-Modelle integrierend zu diskutieren und dabei Antworten auf drei bis dato nicht abschließend beantwortete Fragen zu suchen: 1. Was ist Nutzung? 2. Wie lassen sich Nutzungsprozesse empirisch erfassen? 3. Wovon hängt es ab, ob Schüler*innen Lerngelegenheiten im Unterricht nutzen? Auf dieser Basis skizziere ich mögliche Entwicklungsrichtungen künftiger Forschung über Lernen im Unterricht. So argumentiere ich, dass besonders Analysen von Ursachen für individuelle Unterschiede in Schwankungen der Nutzung über die Zeit hinweg das Verständnis des Zusammenspiels zwischen Unterrichtsangebot, individuellen Merkmalen und der Nutzung des Angebotes weiter voranbringen können. Stärker berücksichtigt werden sollte künftig außerdem die theoretische Annahme, dass die Beziehungen zwischen diesen Faktoren in vielen Fällen reziprok und nicht monodirektional sind. Weiterhin könnte es fruchtbar sein, nicht nur typische Reaktionen auf bestimmte Unterrichtskonstellationen zu untersuchen, sondern Möglichkeitsräume, die durch spezifische Unterrichtsereignisse eröffnet werden, zu explorieren. Auf einer forschungspraktischen Ebene erscheint es – aufgrund der multiplen Herausforderungen bei der Messung von Nutzung – schließlich ratsam, künftig stärker auf Multi-Method-Designs zurückzugreifen.
Study of water quality, socio-economic status and policy intervention in spring ecosystems of Tripura, Northeast India
Authors: Barman Prabir , Ghosh Jayanta , Deb Sourabh 
Published: April 2022

AbstractSpring is vital in all hilly areas. Without question, springs have aided in the advancement of human civilization. Mountain springs supply water to rural families in the Northeast. This spring ecological study was conducted in Dhalai, Tripura, with socio-economic policy significance. The springs chosen were Jamircherra (JS) and Govindabari (GS). The seasonal features of each spring were studied. The monsoon season is used to bring the life-giving flow of perennial springs. Several water quality indicators like WT, pH, EC, TDS, Turb, TH, DO, BOD, Ca+2, Mg+2, Cl−, No3, Po4were examined to assess the risk of spring contamination. The most common aberrant results are samples having excessive phosphate (PO42−) and turbidity levels compared to norms. The spring's water quality was tested using the weighted arithmetic index methodology. The water quality at the two springs was adequate but not great throughout the year, causing human deaths from water-borne diseases. Thus, policy implementation was emphasized to save the spring and human life. A physicochemical evaluation of both springs was used to describe a techno-legal component of Environmental regulations.
Anosov flows on -manifolds: the surgeries and the foliations
Authors: BONATTI CHRISTIAN , IAKOVOGLOU IOANNIS 
Published: April 2022

AbstractEvery Anosov flow on a 3-manifold is associated to a bifoliated plane (a plane endowed with two transverse foliations
$F^s$
and
$F^u$
) which reflects the normal structure of the flow endowed with the center-stable and center-unstable foliations. A flow is
$\mathbb{R}$
-covered if
$F^s$
(or equivalently
$F^u$
) is trivial. On the other hand, from any Anosov flow one can build infinitely many others by Dehn–Goodman–Fried surgeries. This paper investigates how these surgeries modify the bifoliated plane. We first observe that surgeries along orbits corresponding to disjoint simple closed geodesics do not affect the bifoliated plane of the geodesic flow of a hyperbolic surface (Theorem 1). Analogously, for any non-
$\mathbb{R}$
-covered Anosov flow, surgeries along pivot periodic orbits do not affect the branching structure of its bifoliated plane (Theorem 2). Next, we consider the set
$\mathcal{S}urg(A)$
of Anosov flows obtained by Dehn–Goodman–Fried surgeries from the suspension flow
$X_A$
of any hyperbolic matrix
$A \in SL(2,\mathbb{Z})$
. Fenley proved that performing only positive (or negative) surgeries on
$X_A$
leads to
$\mathbb{R}$
-covered Anosov flows. We study here Anosov flows obtained by a combination of positive and negative surgeries on
$X_A$
. Among other results, we build non-
$\mathbb{R}$
-covered Anosov flows on hyperbolic manifolds. Furthermore, we show that given any flow
$X\in \mathcal{S}urg(A)$
there exists
$\epsilon>0$
such that every flow obtained from
$X$
by a non-trivial surgery along any
$\epsilon$
-dense periodic orbit
$\gamma$
is
$\mathbb{R}$
-covered (Theorem 4). Analogously, for any flow
$X \in \mathcal{S}urg(A)$
there exist periodic orbits
$\gamma_+,\gamma_-$
such that every flow obtained from
$X$
by surgeries with distinct signs on
$\gamma_+$
and
$\gamma_-$
is non-
$\mathbb{R}$
-covered (Theorem 5).
Benefits and Challenges of a Hybrid Distance Education Program for Autistic School-Age Students: Parent, Student and Teacher Perspectives
Authors: Haas Kaaren , Carter Mark , Stephenson Jennifer , Gibbs Vicki 
Published: April 2022

AbstractParents whose autistic1 child’s needs are not met within mainstream schooling may seek alternative modes of education, such as home or distance education. There is a paucity of research on the delivery of home or distance education programs for autistic students. This study reports on the experiences of parents, students and teachers in the inaugural year of Australia’s first hybrid distance education program (distance education with parent/carers as supervisors) specifically designed for autistic students. Interviews with eight parents, four students and two teachers gathered their perceptions of the program’s benefits, challenges and suggestions for improvements. All parents, students and teachers reported positive overall perceptions of and experiences in the program, and a range of outcomes for students and parents. Flexibility was identified as a key benefit of the program. Challenges identified included a lack of opportunities for students’ social interactions and the effort required of parents to support their child’s participation. Additional longitudinal research is needed to determine the long-term impact of programs of this type and to evaluate strategies for increasing student independence.

Published: April 2022

AbstractObjectivesThis study aimed: to evaluate the association between coronavirus disease 2019 infection and olfactory and taste dysfunction in patients presenting to the out-patient department with influenza-like illness, who underwent reverse transcription polymerase chain reaction testing for coronavirus; and to determine the sensitivity, specificity, and positive and negative predictive values of olfactory and taste dysfunction and other symptoms in these patients.MethodsPatients presenting with influenza-like illness to the study centre in September 2020 were included in the study. The symptoms of patients who tested positive for coronavirus on reverse transcription polymerase chain reaction testing were compared to those with negative test results.ResultsDuring the study period, 909 patients, aged 12–70 years, presented with influenza-like illness; of these, 316 (34.8 per cent) tested positive for coronavirus. Only the symptoms of olfactory and taste dysfunction were statistically more significant in patients testing positive for coronavirus than those testing negative.ConclusionDuring the pandemic, patients presenting to the out-patient department with sudden loss of sense of smell or taste may be considered as positive for coronavirus disease 2019, until proven otherwise.
