Published: July 2023

Background
Women who use hormonal contraception face delayed return of fertility upon discontinuation. There was limited evidence of fertility return after hormonal contraceptive discontinuation in the study area. Hence this study assessed fertility return after hormonal contraceptive discontinuation and associated factors among pregnant women attending Family Guidance Association Ethiopia (FGAE) Dessie model clinic, Northeast Ethiopia, 2019.

Methods
A cross-sectional study was conducted on 423 samples selected by using systematic random sampling. Data were collected by face-to-face interview using a pretested and structured questionnaire and reviewing client records. Data were entered using Epi Data version 3.1 and analyzed using SPSS version 23. Both bi-variable and multivariable binary logistic regressions were used to identify predictors of delayed fertility return. Adjusted odds ratio (AOR) along with a 95% Confidence Interval (CI) was used to measure the strength and the direction of the association and statistical significance was declared at a P-value less than 0.05.

Result
The proportion of fertility return among currently pregnant women after discontinuation of any hormonal contraceptive methods was 88.6% (95% CI; (85.6%-92%)). The proportion of fertility return among Depo-Provera, implant, Intrauterine Contraceptive Device (IUCD), and Oral Contraceptive Pill (OCP) users was 75%, 99.1%, 100%, and 97.8% respectively. Age, (AOR = 5.37, (95% CI; (1.48, 13.6)) and using Depo-Provera (AOR = 4.82, 95% CI; (1.89, 14.2)) had a significant association with delayed fertility return.

Conclusions
The proportion of fertility return among women after discontinuation of any hormonal contraceptive methods was high. Age and using Depo-Provera had a positive association with delayed fertility return. This study recommends a contraceptive counseling approach that addresses concerns about delay in the return of fertility after hormonal contraceptive discontinuation to avoid confusion among family planning users.

Published: July 2023

Introduction
Many healthcare workers have switched from face-to-face clinical supervision to telesupervision since the onset of the COVID-19 pandemic. Given the rise in prevalence of telesupervision and continuing remote working arrangements, telesupervision is no longer only limited to rural areas. As this remains an under-investigated area, this study aimed to explore supervisor and supervisee first hand experiences of effective telesupervision.

Methods
A case study approach combining in-depth interviews of supervisors and supervisees, and document analysis of supervision documentation was used. De-identified interview data were analysed through a reflective thematic analysis approach.

Results
Three supervisor-supervisee pairs from occupational therapy and physiotherapy provided data. Data analysis resulted in the development of four themes: Benefits vs limitations and risks, not often a solo endeavour, importance of face-to-face contact, and characteristics of effective telesupervision.

Discussion
Findings of this study have confirmed that telesupervision is suited to supervisees and supervisors with specific characteristics, who can navigate the risks and limitations of this mode of clinical supervision. Healthcare organisations can ensure availability of evidence-informed training on effective telesupervision practices, as well as investigate the role of blended supervision models to mitigate some risks of telesupervision. Further studies could investigate the effectiveness of utilising additional professional support strategies that complement telesupervision, including in nursing and medicine, and ineffective telesupervision practices.
From positional representation of numbers to positional representation of vectors
Authors: Farkas Izabella  Ingrid , Pelantová Edita , Svobodová Milena 
Published: July 2023

To represent real m-dimensional vectors, a positional vector system given by a non-singular matrix M ∈ ℤm×m and a digit set Ɗ ⊂ ℤm is used. If m = 1, the system coincides with the well known numeration system used to represent real numbers. We study some properties of the vector systems which are transformable from the case m = 1 to higher dimensions. We focus on an algorithm for parallel addition and on systems allowing an eventually periodic representation of vectors with rational coordinates.
Zagadnienie podmiotowości prawnej prebendy w świetle uregulowań kościelnych i państwowych
Authors: Skoczykłoda Paweł 
Published: July 2023

Artykuł przedstawia zagadnienie podmiotowości prawnej prebend, zwanych też beneficjami, które od wieków stanowiły istotną część organizacji kościelnej. Aby mogły swobodnie realizować swoje zadania, Kościół katolicki przyznawał im osobowość prawną, co w średniowieczu było w pełni uznawane przez ówczesne systemy państwowe. Jednak wraz z laicyzacją Europy uznawanie prebend za osoby prawne przestało być automatyczne, a z czasem państwa zupełnie przestały uznawać beneficja za podmiot prawa świeckiego. Mimo to dalej były one traktowane przez Kościół jako jego jednostki organizacyjne, uprawnione do posiadania własnego majątku. Choć dziś prebendy nie są już spotykane, dalej wynikają z nich liczne wątpliwości praktyczne. Autor poszukuje rozwiązania problemu przysługiwania własności beneficjom i przedstawia złożoną ewolucję podejścia do owej materii w Polsce. Pozwala to ustalić, iż nieruchomości, których własność przysługiwała przed laty prebendom, powinny zostać przypisane tym podmiotom prawnym Kościoła, z którymi działalność beneficjum była związana, lub tym, które realnie korzystały z nieruchomości prebend po zaprzestaniu przez nie działalności.
Properties of a subclass of analytic functions defined by Riemann-Liouville fractional integral applied to convolution product of multiplier transformation and Ruscheweyh derivative
Authors: Alb Lupaş Alina , Acu Mugur 
Published: July 2023

Abstract
The contribution of fractional calculus in the development of different areas of research is well known. This article presents investigations involving fractional calculus in the study of analytic functions. Riemann-Liouville fractional integral is known for its extensive applications in geometric function theory. New contributions were previously obtained by applying the Riemann-Liouville fractional integral to the convolution product of multiplier transformation and Ruscheweyh derivative. For the study presented in this article, the resulting operator is used following the line of research that concerns the study of certain new subclasses of analytic functions using fractional operators. Riemann-Liouville fractional integral of the convolution product of multiplier transformation and Ruscheweyh derivative is applied here for introducing a new class of analytic functions. Investigations regarding this newly introduced class concern the usual aspects considered by researchers in geometric function theory targeting the conditions that a function must meet to be part of this class and the properties that characterize the functions that fulfil these conditions. Theorems and corollaries regarding neighborhoods and their inclusion relation involving the newly defined class are stated, closure and distortion theorems are proved, and coefficient estimates are obtained involving the functions belonging to this class. Geometrical properties such as radii of convexity, starlikeness, and close-to-convexity are also obtained for this new class of functions.

Abstract
Supercritical hydrothermal combustion, as a quick homogeneous oxidizing process, offers a promising treatment option for industrial wastewater. This paper established a computational fluid dynamics model of a water-cooled hydrothermal combustion burner to investigate the thermal flame characteristics. The effects of the fuel mass flow rate, fuel concentration, initial reactor temperature, reaction pressure, and oxidant temperature on the thermal combustion ignition were revealed. The results indicate that the fuel concentration (from 10 wt% to 60 wt%) and initial reactor temperature (from 623 to 773 K) had less effect on the ignition temperature. In contrast, the ignition temperature increases by 398 K with increasing fuel mass flow rate (from 24 kg h−1 to 1080 kg h−1). As the oxygen temperature increases (from 273 to 673 K), the ignition temperature gradually decreases to 573 K and then increases. An increase in reaction pressure can facilitate a decrease in ignition temperature to a certain extent, and the optimal reaction pressure is 25 MPa. This study provides a vital reference for a hydrothermal burner’s scale-up design and ignition operation.
The Kantian Sublime Reflected in the Kierkegaardian Sublime
Authors: Parding Mathias 
Published: July 2023

Abstract
Occupying a seemingly minor role in the authorship of Kierkegaard, the concept of “the sublime” has not received much attention in the reception, compared to that of other more prominent concepts. This could essentially imply one of two things: either that the sublime is not an important theme for Kierkegaard, or that it is so pervasively present, that the reader does not know how to conceive it, let alone get a hold of a tangible definition of it. Proceeding from the latter assumption, this article expounds in what sense the sublime occupies a pivotal role in Kierkegaard’s philosophy mediating between the aesthetic and the religious sphere. Using the Kantian conceptual framework of the sublime as my continual point of reference, I wish to show how Kierkegaard both remains loyal to certain aspects of this heritage, and at the same time transports the sublime to an entirely new plateau. Setting the stage for a modern discourse of the sublime will enable us to see in what sense the sublime enters a central position in Kierkegaard’s philosophy, being the feeling that awakens the individual from his social immurement and propels him into his path of self-realization.
The Hong Kong Reception of Kierkegaard: From the 1950s to the Present
Authors: Ka Pok Tam Andrew 
Published: July 2023

Abstract
Early in the 1950s, Kierkegaard’s philosophy had already been introduced to the academic circle of Hong Kong, which was an in-betweener between Chinese and Western cultures. Nevertheless, while Kierkegaard was frequently discussed by the Japanese philosophers of the Kyoto school, Hong Kong Chinese philosophers (remarkably New Confucians) from the 1950s to the 2010s rarely appreciate Kierkegaard’s philosophy. This paper argues that these Chinese philosophers are uninterested in Kierkegaard because their major concerns are the preservation of traditional Chinese culture in Hong Kong, and Kierkegaard’s philosophy seems to be irrelevant to their visions and missions, and Kierkegaard’s Christian ontology seems to be inconsistent with New Confucian ontology.
The Second War Between the States: How the United States Became the World’s Best Tax Haven
Authors: Moran Beverly 
Published: July 2023

Abstract
We want government to help us prosper. For working people, prosperity requires employment and employment requires business. After World War II, most of the world was either devastated or underdeveloped leaving the United States without foreign competition. Local competition took its place. The States and local governments competed against one another on their natural resources, access to transportation, infrastructure, schools, and work force. These are the products of government spending. Some States did not have much to attract economic development. They created their own attributes instead. For example, right to work laws attracted companies that wanted to avoid unions and no usuary limits attracted credit card companies who wanted to charge high rates. Other States offered tax holidays. Move here and pay no tax for ten years. But saving money in taxes lost its appeal when other jurisdictions offered even more. Rather than build good sewage systems or roads for everyone, towns provided free infrastructure built to company specifications in addition to tax incentives. By the 1970s, firms learned that they could get States and localities to bid against one another. Each providing a package of bigger incentives. We can see the result of these races to the bottom in cities and towns that gave companies whatever they wanted only to find themselves with vacant factories and roads leading to nowhere. While the States were competing with one another, the rest of the world was emerging from war. Like the States, these countries wanted to help their citizens prosper. For those without natural resources or great infrastructure or educated workers, one alternative was to become a tax haven. A tax haven is the other side of a tax incentive. With tax incentives, a government gives up the right to tax in the hope that a firm's relocation will bring its citizens success. In a tax haven, a government hopes to improve its citizens’ fortune by helping a foreign taxpayer avoid another government’s taxes. Whether tax incentive or tax haven, in the end, the result is the same. The stakes get higher and higher. The companies and foreign taxpayers move from site to site. They take everything they can get and then convince another government to give more. Now a decade of investigative journalism shows that not only are the States in race to the bottom with their own tax revenues, but they are also transforming themselves into tax havens thus helping foreign taxpayers deplete their home countries’ revenues. This paper is a cautionary tale. It shows what makes the United States the world's favorite tax haven and examines what we can expect if this trend continues.

Abstract
This research aimed to evaluate the eradication efficacy, safety, and gastrointestinal symptom relief rates of empirical bismuth quadruple therapy, high-dose dual therapy, and resistance gene-based triple therapy in primary eradication patients in Yangzhou, China. It also investigated the possible factors influencing the success of different Helicobacter pylori eradication regimens. A single-center, prospective, open-label, randomized controlled study was performed from December 2020 and October 2021, in which 255 patients with H. pylori infection were assigned in a 1:1:1 ratio to the three different groups. Our results showed that high-dose dual therapy (91.0%, 71/78) and resistance gene-based triple therapy (94.9%, 75/79) achieved eradication rates and compliance equivalent to those of empirical bismuth quadruple therapy (85.3%, 64/75) in the per-protocol analysis, while high-dose dual therapy had lower rates of adverse events (11.5%, 9/78, P < 0.05), fewer side effects, and greater safety. Most patients’ gastrointestinal discomfort symptoms improved after eradication of H. pylori. Poor compliance (P < 0.05) and antibiotic resistance (P < 0.05) were risk factors for the efficacy of H. pylori eradication. Therefore, the appropriate regimen can be individualized for eradication therapy in clinical practice according to the patient’s resistance and tolerance to the drug.

Abstract
Clinical presentation of central nervous system (CNS) infections caused by varicella-zoster virus (VZV) is highly sophisticated, making identification challenging. We retrospectively reported 18 cases of VZV neurologic disease confirmed by metagenomic next-generation sequencing (mNGS). The detection rate of mNGS was higher than that of PCR assay (100 vs 66.7%, p < 0.05) and serum IgM antibody (100 vs 68.8%, p < 0.05) measurement. Of the 18 cases, five patients were diagnosed with acute meningitis, three with acute meningitis combined with facial neuritis, three with acute meningitis combined with polycranial neuritis, and the remaining seven with various clinical diagnoses. Typical clinical symptoms included headache (15), fever (9), and rash (11). Cranial or spinal MRI showed abnormalities in 12 patients, and 17 patients had obvious neurological symptoms. The predominant genotype of VZV in this study was genotype J (100%, 10/10). All patients were treated with acyclovir/penciclovir and dexamethasone, 16 recovered and 2 died. Our study highlights the good performance of mNGS in diagnosing CNS infection caused by VZV. It could provide additional diagnostic evidence in patients with diverse clinical spectrum and variable manifestations.

Abstract
The decarburization layer can be detrimental and lead failures in press hardened steels. This work investigates the effect of decarburization layer on the fatigue crack origination and growth on press hardened parts of uncoated 22MnB5 steel. The decarburization layer was analyzed by light microscope, scanning electron microscope, and microhardness measurements. It was found that decarburization layer has two distinct zones indicating complete and partial decarburization. To understand the effect of decarburization on crack origination, high cycle fatigue tests were performed on samples from press hardened parts in decarburized and polished (nondecarburized) conditions. The results have shown that the fatigue performance of press hardened steels in polished condition outperforms the fatigue samples in decarburized condition. In fractographic investigations, it was seen that decarburization is not only responsible for crack origination but also affects crack propagation by having full and partial decarburization zones. The full decarburization zone was acted as surface crack origination source. In the partial decarburization zone, the crack propagation behavior was changed by a complex phase microstructure of bainite, ferrite, and martensite.

Published: July 2023

Abstract
Weyl semimetals hold great promise in revolutionizing nonreciprocal optical components due to their unique topological properties. By exhibiting nonreciprocal magneto-optical effects without necessitating an external magnetic field, these materials offer remarkable miniaturization opportunities and reduced energy consumption. However, their intrinsic topological robustness poses a challenge for applications demanding tunability. In this work, we introduce an innovative approach to enhance the tunability of their response, utilizing multilayered configurations of twisted anisotropic Weyl semimetals. Our design enables controlled and reversible isolation by adjusting the twist angle between the anisotropic layers. When implemented in the Faraday geometry within the mid-IR frequency range, our design delivers impressive isolation, exceeding 50 dB, while maintaining a minimal insertion loss of just 0.33 dB. Moreover, the in-plane anisotropy of Weyl semimetals eliminates one or both polarizers of conventional isolator geometry, significantly reducing the overall dimensions. These results set the stage for creating highly adaptable, ultra-compact optical isolators that can propel the fields of integrated photonics and quantum technology applications to new heights.
COMPETÊNCIAS DIGITAIS NO CONTEXTO IBÉRICO: UM ESTUDO DE EVIDÊNCIAS
Authors: Santos Cassio , Pedro Neuza , Mattar João , Carrascal Silvia 
Published: July 2023

Introducción. Las Tecnologías de la Información y la Comunicación (TIC) son esenciales para comprender las recientes transformaciones económicas, sociales, políticas y culturales, teniendo el poder público un importante papel en la provisión de un acceso adecuado y satisfactorio a las necesidades de la sociedad moderna para todas las personas sin distinción de clase social o nivel de educación. Metodología. La literatura indica la posición destacada de España en materia de competencias digitales en comparación con otros Estados-Miembros. Este artículo pretende profundizar en esta evidencia en la Península Ibérica, en consideración de varios factores: (a) los datos del Digital Economy & Society Index (DESI); (b) el volumen de producción científica sobre competencia digital; (c) los proyectos catalogados en DigComp into action; y (d) las estructuras y acciones de apoyo a las competencias digitales, a través de enfoques metodológicos cuantitativos y cualitativos. Resultados. Portugal ha mostrado en los últimos años una inversión en el proceso de digitalización, pero muy cercana a la media de los Estados-Miembros, ocupando la 15ª posición en el DESI. Por el contrario, España ocupa la 7ª posición en el DESI y la 13ª en PIB per cápita, presentando España datos más favorables sobre el resto de los factores estudiados. Discusión. Varias políticas públicas y acciones implementadas por España contribuyen ciertamente al resultado del país, lo que puede ser fácilmente identificado en los parámetros de producción científica y en el análisis DigComp into Action. Se identificó que Portugal estaba a la vanguardia en el desarrollo de marcos de referencia y certificación de competencias digitales (2008); sin embargo, con una brecha significativa en la implementación de programas dirigidos a las competencias digitales, se identificó el movimiento opuesto en España. Conclusiones. La continuidad de las acciones y programas puede haber sido un promotor de las otras evidencias encontradas, como el número más significativo de proyectos mapeados en DigComp Into Action, tener el 13º PIB per cápita de los Estados-Miembros y estar posicionado en el 7º puesto de DESI.
