Microcavity platform for widely tunable optical double resonance
Authors: Flågan Sigurd , Maletinsky Patrick , Warburton Richard J. , Riedel Daniel 
Published: August 2022

Tunable open-access Fabry–Perot microcavities are versatile and widely applied in different areas of photonics research. The open geometry of such cavities enables the flexible integration of thin dielectric membranes. Efficient coupling of solid-state emitters in various material systems has been demonstrated based on the combination of high quality factors and small mode volumes with a large-range in situ tunability of the optical resonance frequency. Here, we demonstrate that by incorporating a diamond micromembrane with a small thickness gradient, both the absolute frequency and the frequency difference between two resonator modes can be controlled precisely. Our platform allows both the mirror separation and, by lateral displacement, the diamond thickness to be tuned. These two independent tuning parameters enable the double-resonance enhancement of nonlinear optical processes with the capability of tuning the pump laser over a wide frequency range. As a proof of concept, we demonstrate a

threshold for establishing Raman lasing is within reach. Our findings pave the way to the creation of a universal, low-power frequency shifter. The concept can be applied to enhance other nonlinear processes such as second harmonic generation or optical parametric oscillation across different material platforms.
A mixed methods study of community-based health insurance enrollment trends and underlying challenges in two districts of northeast Ethiopia: A proxy for its sustainability
Authors: Hussien Mohammed , Azage Muluken , Bayou Negalign Berhanu 
Published: August 2022

Background
The term "community-based health insurance" refers to a broad range of nonprofit, prepaid health financing models designed to meet the health financing needs of disadvantaged populations, particularly those in the rural and informal sectors. Due to their voluntary nature, such initiatives suffer from persistently low coverage in low- and middle-income countries. In Ethiopia, the schemes’ membership growth has not been well investigated so far. This study sought to examine the scheme’s enrollment trend over a five-year period, and to explore the various challenges that underpin membership growth from the perspectives of various key stakeholders.

Methods
The study employed a mixed methods case study in two purposively selected districts of northeast Ethiopia: Tehulederie and Kallu. By reviewing the databases of health insurance schemes, quantitative data were collected retrospectively from 2017 to 2021 to examine enrollment trends. Trends for each performance indicator were analyzed descriptively for the period under study. Face-to-face interviews were conducted with nine community members and 19 key informants. Study participants were purposely selected using the maximum variation technique. Interviews were audio recorded, transcribed verbatim, and translated into English. Thematic analysis was employed with both deductive and inductive coding approaches.

Results
Over the course of the study period, enrollment in the scheme at both districts exhibited non-linear trends with both positive and negative growth rates being identified. Overall, the scheme in Tehulederie has a relatively higher population coverage and better membership retention, which could be due to the strong foundation laid by a rigorous public awareness campaign and technical support during the pilot phase. The challenges contributing to the observed level of performance have been summarized under four main themes that include quality of health care, claims reimbursement for insurance holders, governance practices, and community awareness and acceptability.

Conclusions
The scheme experienced negative growth ratios in both districts, indicating that it is not functionally viable. It will fail to meet its mission unless relevant stakeholders at all levels of government demonstrate political will and commitment to its implementation, as well as advocate for the community. Interventions should target on the highlighted challenges in order to boost membership growth and ensure the scheme’s viability.

Published: August 2022

Background
COVID-19 has rapidly emerged as a global public health threat with infections recorded in nearly every country. Responses to COVID-19 have varied in intensity and breadth, but generally have included domestic and international travel limitations, closure of non-essential businesses, and repurposing of health services. While these interventions have focused on testing, treatment, and mitigation of COVID-19, there have been reports of interruptions to diagnostic, prevention, and treatment services for other public health threats.

Objectives
We conducted a scoping review to characterize the early impact of COVID-19 on HIV, tuberculosis, malaria, sexual and reproductive health, and malnutrition.

Methods
A scoping literature review was completed using searches of PubMed and preprint servers (medRxiv/bioRxiv) from November 1st, 2019 to October 31st, 2020, using Medical Subject Headings (MeSH) terms related to SARS-CoV-2 or COVID-19 and HIV, tuberculosis, malaria, sexual and reproductive health, and malnutrition. Empiric studies reporting original data collection or mathematical models were included, and available data synthesized by region. Studies were excluded if they were not written in English.

Results
A total of 1604 published papers and 205 preprints were retrieved in the search. Overall, 8.0% (129/1604) of published studies and 10.2% (21/205) of preprints met the inclusion criteria and were included in this review: 7.3% (68/931) on HIV, 7.1% (24/339) on tuberculosis, 11.6% (26/224) on malaria, 7.8% (19/183) on sexual and reproductive health, and 9.8% (13/132) on malnutrition. Thematic results were similar across competing health risks, with substantial indirect effects of the COVID-19 pandemic and response on diagnostic, prevention, and treatment services for HIV, tuberculosis, malaria, sexual and reproductive health, and malnutrition.

Discussion
COVID-19 emerged in the context of existing public health threats that result in millions of deaths every year. Thus, effectively responding to COVID-19 while minimizing the negative impacts of COVID-19 necessitates innovation and integration of existing programs that are often siloed across health systems. Inequities have been a consistent driver of existing health threats; COVID-19 has worsened disparities, reinforcing the need for programs that address structural risks. The data reviewed here suggest that effective strengthening of health systems should include investment and planning focused on ensuring the continuity of care for both rapidly emergent and existing public health threats.
“Don't Look at Me!”: Deviance and the Uncontrollable Image of Black Motherhood in Moonlight
Authors: Wooten Terrance 
Published: August 2022

Abstract
Contemporary movements against state-sanctioned violence have used rhetorical refrains to mark and practice dissent, as evidenced by the proliferation of “hands up, don't shoot”; “#sayhername”; and “#blacklivesmatter.” These refrains provide a specific discourse through which critiques of violence, surveillance, and economic injustice are galvanized, connecting activists and demonstrators across geospatial and temporal landscapes. Political refrains are more than just rallying cries; they also function as edicts, as commands that often disrupt the very practices they name. In this article, I argue that Barry Jenkins's use of the “Don't look at me!” refrain in Moonlight, expressed by Little/Black's mother, Paula, functions to name and obfuscate the racialized and gendered surveillance of Black deviance throughout the film. Set in the midst of the War on Drugs, culture of poverty thesis, and a post-Moynihan Report political culture that blamed the failure of the Black community on the Black matriarch, Moonlight offers an alternative reading strategy that instead of re-pathologizing Black motherhood and queer sociality actually renders visible and mutable the controlling images used to surveil and flatten Black subjectivity. Paula's “Don't look at me!” attempts to render her own body out of sight in order to ask viewers to look beyond her, to shift the pathologizing lens away from her to instead think of the various systems of power operating that inform her choices and epidermalize her body as a problem.

PERAMALAN INDEKS HARGA KONSUMEN INDONESIA MENGGUNAKAN METODE SEASONAL-ARIMA (SARIMA)
Authors: YAHYA ARYA 
Published: August 2022

The pattern of changes in the Consumer Price Index (CPI) is very important to observe from time to time because it is closely related to economic indicators such as the amount of money in circulation, exchange rates, interest rates, and other economic indicators. This study aims to form a model and predict the Indonesian Consumer Price Index using the SARIMA method. The data used in modeling are monthly CPI data for the period January 2012 to February 2022. The best model for predicting Indonesia's CPI is the SARIMA (0,1,1)(0,1,1)12 model. This study examines the CPI value in January and February 2022 which is not included in the estimation model, the estimation results (108,08 and 108,20) are very close to the actual CPI value issued by the Central Statistics Agency.
Discovering How to Do Reflexivity and Self-Reflexivity: A Longitudinal Empirical Research Findings
Authors: De Verlaine Emmanuelle 
Published: August 2022

Reflexivity is known to be a mental process where a person takes distance to oneself to analyze and take a critical perspective over own feelings, actions and intentions in order to realign own practice. Reflexivity is therefore a form of metacognitive brain functionality reaching a state of mind’s sense of acute awareness. The reflexivity’s functionality has been recognized as valuable to improve professional practices. The main gap in research and literature is to explicate how to do reflexivity and most of all, how to apply it to all aspects of human life toward self-actualization. This research aims at answering at: How to Do reflexivity and Self-Reflexivity? To answer this question a 17 year-long longitudinal Action-Research investigations reveals how to learn and practice reflexivity. This paper also reveals how reflexivity can be applied to aim at one’s well-being and self-actualization. The discussion addresses the long-term impact of practicing reflexivity coupled with mindfulness as an ability to reach self-liberation.
Urysohn and Hammerstein operators on Hölder spaces
Authors: Pötzsche Christian 
Published: August 2022

Abstract
We present an application-oriented approach to Urysohn and Hammerstein integral operators acting between spaces of Hölder continuous functions over compact metric spaces. These nonlinear mappings are formulated by means of an abstract measure theoretical integral involving a finite measure. This flexible setting creates a common framework to tackle both such operators based on the Lebesgue integral like frequently met in applications, as well as, e.g., their spatial discretization using stable quadrature/cubature rules (Nyström methods). Under suitable Carathéodory conditions on the kernel functions, properties like well-definedness, boundedness, (complete) continuity and continuous differentiability are established. Furthermore, the special case of Hammerstein operators is understood as composition of Fredholm and Nemytskii operators. While our differentiability results for Urysohn operators appear to be new, the section on Nemytskii operators has a survey character. Finally, an appendix provides a rather comprehensive account summarizing the required preliminaries for Hölder continuous functions defined on metric spaces.
LpHardy's identities and inequalities for Dunkl operators
Authors: Wang Jianxiong 
Published: August 2022

AbstractThe main purpose of this article is to establish theLp{L}^{p}Hardy’s identities and inequalities for Dunkl operator on any finite balls and the entire spaceRN{{\mathbb{R}}}^{N}. We also prove Hardy’s identities and inequalities on certain domains with distance function to the boundary∂Ω\partial \Omega. In particular, we use the notion of Bessel pairs introduced in Ghoussoub and Moradifam to extend Hardy’s identities for the classical gradients obtained by Lam et al., Duy et al., Flynn et al. to Dunkl gradients introduced by Dunkl. Our Hardy’s identities with explicit Bessel pairs significantly improve many existing Hardy’s inequalities for Dunkl operators.
Resource Orchestration in Hub-Based Entrepreneurial Ecosystems: A Case Study on the Seaweed Industry
Authors: Lu Baozhou , Zhang Song 
Published: August 2022

Abstract
Hub-based entrepreneurial ecosystems (HEEs) have become an important venue for entrepreneurship. This study examines how ecosystem-specific resources and capabilities are orchestrated by ecosystem actors (i.e., hub firms and ecosystem entrepreneurs) to support the development of new ventures in the context of HEEs. Using an explorative single case study approach, we uncover nine distinctive resource orchestration subprocesses that are grouped into three aggregate processes that help sustain enduring entrepreneurship in the HEE context. Our findings extend and complement the literature on entrepreneurship and ecosystems by developing a new resource orchestration model and by illustrating how resource orchestration in an HEE facilitates the synergies across ecosystem ventures as well as the synergies between hub firms and ecosystem entrepreneurs in coexploring and coexploiting new opportunities.

Authors: Mouhouche Faiza , Djafri Kahina , Dehmas Mokrane , Chibane Kahina , Ksentini Safa 
Published: August 2022

Abstract
In this article, a miniaturized patch antenna using fractal DGS and SRR DMS for GSM1800, C band and WiMAX applications is presented and investigated. Antenna miniaturization and multiband are accomplished by employing a fractal loop on the DGS structure and a split ring resonator slot in the patch. The proposed radiator has a hexagonal shape that operates at 6.8 GHz. To achieve downsize of 20.58, 38.22, 55.14 and 72.75% an antenna is designed using DGS and DMS structures for quad-band application appearing at 1.85, 3.05, 4.2, and 5.4 GHz. Simulated and tested data are investigated. The prototype antenna has adequate advantages, with a simple structure, compact size, multiband, and uniform radiation patterns.

Fractal analysis of retinal vasculature in relation with retinal diseases – an machine learning approach
Authors: Venkataramani Deepika , Veeranan Jeyalakshmi , Pitchai Latha 
Published: August 2022

Abstract
Diabetic retinopathy (DR) is caused by diabetes mellitus. Vision loss occurs as a result of DR. The goal of this study was to use the DIARETDB-1, DIARETDB-0, STARE, MESSIDOR, E-ophtha-EX, and E-ophtha-MA databases to do Fourier fractal analysis and see how it is related to retinal illnesses. Following the extraction and inversion of colour channels, blood vessel augmentation was conducted. For the blood vessel enhanced image, the fractal dimension was determined. For DR patients and normal patients, measures such as standard deviation, mean, and significance were calculated. In the E-ophtha-EX database, significance was realized. In the DIARETDB-1, STARE, and DIARETDB-0 databases, the mean fractal value for normal patients is higher than for DR patients. The STARE database’s forecast of the association between fractal dimensions and various retinal disorders and the E-ophtha-EX database’s accomplishment of significance are the study’s main highlights. This study also improved the robustness of the blood vessel extraction there and increased the accuracy of its diagnosis.

Tiefenscannende Interferometrie mit Unterabtastung in Kombination mit einem neuartigem RGB-Doppelpuls-Korrelations- Algorithmus zur Topographieerfassung
Authors: Gollor Pascal , Lehmann Peter 
Published: August 2022

Zusammenfassung
In diesem Beitrag wird ein Messsystem vorgestellt, das auf einem tiefenscannenden Micheslon-RGB-Interferometer zur Erfassung von 3DMikrotopographien beruht. Bei der Messung des Interferenzsignals wird bewusst das Nyquist-Shannon- Abtasttheorem verletzt, so dass die Messgeschwindigkeit im Vergleich zu einem klassischen Weißlichtinterferometer (WLI) signifikant erhöht werden kann, ohne auf die Vorteile des WLI, wie einen großen Eindeutigkeitsbereich und axialen Messbereich, verzichten zu müssen. Das RGBInterferometer wird mit einem Auswertealgorithmus kombiniert, der die Oberflächentopographie durch eine Korrelationsanalyse zwischen einem Mess- und einem Referenzsignal mit Nanometer-Höhenauflösung bestimmen kann. Der Messprozess wird anhand eines Stufenmessnormals experimentell validiert.
Eigenschaften und spezielle Phänomene von Dehnungssensoren aus Kohlenstoffpartikel-Elastomerverbunden
Authors: Mersch Johannes , Gerlach Gerald 
Published: August 2022

Zusammenfassung
Eine häufig untersuchte Materialklasse für Anwendungen, die hochdehnbare und nachgiebige Sensoren erfordern, sind Elastomere mit einem perkolativen Netzwerk aus Kohlenstoffpartikeln, z.B. Leitruß oder Kohlenstoffnanoröhrchen (CNT Carbon Nano Tubes). Diese haben für neuartige Anwendungen wie weiche Roboter oder Smart Textiles einige Vorteile gegenüber den etablierten Dehnmessstreifen. Gleichzeitig ist ihre Funktionsweise aber noch nicht ausreichend verstanden. Solche Materialien werden in dieser Arbeit als Dehnungssensoren in Bezug auf ihr dynamisches Verhalten untersucht und ihre aktuellen Limitierungen aufgezeigt. Dabei wird ersichtlich, dass derartige Sensoren unter dynamischen Belastungen eine nicht monotone Kennlinie aufweisen, die sich deutlich von der in quasi-statischen Versuchen unterscheidet. Aus den Ergebnissen und einem aufgestellten Netzwerkmodell werden zwei Strategien zur Verbesserung der Sensoreigenschaften abgeleitet, modelliert und experimentell analysiert. Erstens werden durch einen Schmelzspinnprozess verschiedene Grade von Anisotropie realisiert, der die CNT-Füllpartikel in Prozessrichtung orientiert. Zweitens wird durch eine zusätzliche auxetische Trägerstruktur eine lokal negative Querkontraktion erzeugt. Während die dadurch erzeugte Anisotropie nicht ausreichend ist, um eine Verbesserung der Sensoreigenschaften zu erreichen, kann die Dehnungssensitivität durch die auxetische Struktur deutlich gesteigert werden.
Erweiterungen zum Aufbau eines zwei Photonen basierten direkten Laserschreibers zur großflächigen, hochpäzisen Nanostrukturierung
Authors: Häcker Annika-Verena , Manske Eberhard 
Published: August 2022

Zusammenfassung
Zur Realisierung extrem feiner Strukturen spielen direkte Laserschreibprozesse, basierend auf Zwei-Photonen-Absorptionsverfahren (2PA), eine zentrale Rolle in der Mikro- und Nanofabrikation. Dafür ist neben einem Lasersystem ein hochpräzises Positioniersystem notwendig. Meist basieren diese Positioniersysteme auf Prinzipien, die ohne zusätzliche Stiching-Verfahren nur kleine Positionierbereiche ermöglichen. Für piezoelektrische Tische sind zum Beispiel nur einige hundert Mikrometer möglich. Auf Galvanometer-Scannern basierten Systemen können sogar nur Positionierbereiche von wenigen zehn Mikrometern realisiert werden. Um ohne zusätzliche Stiching Verfahren größere Fertigungsbereiche mit hoher Präzision für Mikro- und Nanostrukturierung zu ermöglichen, wurde ein Aufbau aus einem Femtosekundenlaser für 2PA und einer Nanopositionier- und Nanomessmaschine (NMM-1) entwickelt [3]. Die NMM-1 wurde an der TU Ilmenau zusammen mit der SIOS Meßtechnik GmbH entwickelt, mit einem Positioniervolumen von 25mm×25mm×5mm und einer Positionierauflösung im Sub-Nanometerbereich. Dieser Aufbau wurde in den letzten Jahren weiter entwickelt und Strukturbreiten konnten reduziert werden [2]. Der Schwerpunkt liegt dabei auf der Entwicklung einer funktionalen Einheit aus Femtosekundenlaser und NMM-1. Dies soll die Komplexität erhöhen und die Homogenität der geschriebenen Strukturen stark verbessern.
Minimal-invasive faseroptische Endomikroskopie für die Medizin
Authors: Dremel Jakob , Scharf Elias , Kuschmierz Robert , Czarske Jürgen 
Published: August 2022

Zusammenfassung
Endoskope sind für die minimalinvasive Chirurgie essenziell. Dabei ist vor allem ein hohes Auflösungsvermögen bei geringem Durchmesser gefordert. Kommerzielle auf Faserbündel basierte Verfahren verwenden aufgrund der gestörten Phaseninformation lediglich die Intensitätsinformation und erreichen so eine maximale Auflösung von 10 kpx bei einem Endoskopdurchmesser im mm-Bereich. Hier wird ein neuartiges Verfahren vorgestellt, welches durch empfangsseitige Kompensation der Phasenstörung eine Auflösung von ≈ 69 kpx bei gleichzeitig reduziertem Durchmesser von 400 μm erreicht.
