The Effects of Health Sector Fiscal Decentralisation on Availability, Accessibility, and Utilisation of Healthcare Services: A Panel Data Analysis
Authors: Rotulo Arianna , Paraskevopoulou Christina , Kondilis Elias
Published: December 2021

Background: Fiscal decentralisation (FD) is a widely implemented decentralisation policy consisting of the allocation of pooling and spending responsibilities from the central government to lower levels of governance within a country. In 2001, The Italian National Health System (Servizio Sanitario Nazionale, SSN) has introduced a strong element of FD, making regions responsible for their own pooling of resources and for their budgets. Despite the relevance, only few studies exist on health sector-FD in Italy, mostly looking at the effects of FD on infant mortality. Methods: This study performs a fixed-effects panel data analysis of Italian Regions and Autonomous provinces between the years 2001 and 2017, to investigate the effects of health sector-FD on availability, accessibility, and utilisation of healthcare services in Italy. Results: FD decreases availability of staff and hospital beds, decreases utilisation of care, measured by hospitalisation rates, and increases interregional patients’ mobility for healthcare purposes, a finding suggesting increased disparities in access to healthcare. These effects seem to be stronger for public – rather than private – services, and are more prominent in poorer areas. Conclusion: This evidence suggest that FD has created a fragmented and unequal healthcare system, in which levels of availability, utilisation of, and accessibility to resources – as well as the extent of public sector’s retrenchment – coincide with the wealth of the area.
BIARLAH PEREMPUAN YANG MENENTUKAN: TINJAUAN TEOLOGI SEKSUALITAS TERHADAP	KEBERADAAN PEREMPUAN BERDASARKAN KEJADIAN 2:21-25
Authors: Panjaitan Firman
Published: December 2021

Masalah seksualitas menjadi krusial ketika terjadi kekerasan seksual dalam keluarga, termasuk keluarga Kristen. Kekerasan seksual bisa berbentuk fisik dan non-fisik, dan salah satunya adalah tentang keputusan kehamilan seorang perempuan yang dibuat oleh laki-laki. Dikatakan sebagai bentuk kekerasan seksual, karena sesungguhnya yang memiliki rahim adalah perempuan, sehingga keputusan hamil atau tidak harus ditentukan oleh perempuan, bukan laki-laki. Oleh sebab itu, pemahaman seksualitas harus dikembangkan melalui pemahaman yang benar, agar dalam pernikahan dan keluarga Kristen tidak hidup di dalam kekerasan seksual. Jalan menuju hal tersebut adalah menggali pemahaman tentang seksualitas dalam Kejadian 2:21-25 guna membangun teologi seksualitas. Penelitian ini menggunakan metode kualitatif dengan pendekatan studi pustaka yang diperkaya dengan metode eksegesa tekstual terhadap Kejadian 2:21-25. Hasil penelitian mengungkapkan bahwa teologi seksualitas menghantar keluarga untuk menyadari bahwa kedudukan laki-laki dan perempuan adalah seimbang dan masing-masing memiliki haknya sehingga tidak boleh ada intervensi terhadap hak masing-masing. Perempuanlah yang menentukan hak rahimnya, bukan laki-laki.

El profesorado en nuestro contexto educativo se ha visto sumergido por los avances tecnológicos, provocando cambios en sus funciones, gestión académica y comunicación, convirtiéndose en guías, mediadores, facilitadores y motivadores de procesos de aprendizajes significativos y relevantes. Dicha situación refleja la importancia que asume en la actualidad la competencia digital docente. En el presente artículo se presenta un estudio realizado al profesorado de la Universidad de Cádiz, que tiene como objetivos conocer el perfil tecnológico y nivel competencial digital del profesorado de la universidad, así como la existencia de diferencias significativas en la autopercepción de las competencias digitales docentes según la rama de conocimiento a la que pertenecen. Para ello, se utilizó una metodología ex post facto de tipo descriptivo, lo que permite aplicarse una vez que el hecho ya ha sucedido, utilizando como instrumento el cuestionario DigCompEdu Check-in. Entre los resultados obtenidos se puede destacar: la necesidad de aportar una mayor relevancia y apoyo institucional a la formación en competencias digitales docentes, la necesidad de una mayor oferta formativa del profesorado universitario ante la escasa competencia digital docente, También se demuestra que las ramas de conocimiento pueden condicionar el desarrollo de la competência digtital docente en el professorado. El estudio realizado abre camino hacia la posibilidad de contemplar como plan de formación la creación de un entorno formativo que, bajo la arquitectura de t-MOOC ofrezca, de manera gratuita, capacitación del profesorado universitario.
Od dyktatury ekspertów do demokracji nieliberalnej
Authors: Grygieńć Janusz
Published: December 2021

Brak transparentności procesów decyzyjnych typowy dla demokracji liberalnych oraz związany z nim kryzys zaufania obywateli wobec instytucji politycznych to jedne z głównych przyczyn sukcesów odnoszonych przez stronników demokracji nieliberalnej. Zdaniem krytyków liberalizmu zbyt wiele decyzji współcześnie delegowanych jest do ciał nienadzorowanych demokratycznie. Zwolennicy koncepcji demokracji deliberacyjnej formułują różne remedia na tę sytuację. Nie czynią tego jednak stronnicy najpopularniejszej obecnie z wersji demokracji deliberacyjnej – podejścia systemowego do deliberacji. Autor artykułu twierdzi, że podejście to może legitymizować „niedemokratyczny liberalizm” – jedną z przyczyn kryzysu demokracji liberalnej. Celem artykułu jest prezentacja i ocena stosunku zwolenników podejścia systemowego do roli odgrywanej w procesie politycznym przez nienadzorowane demokratycznie gremia eksperckie.
Ultrafast phased-array imaging with pump excitation for closed-crack imaging
Authors: Ohara Yoshikazu , Haupert Sylvain , Li Sinan
Published: December 2021

Nondestructive evaluation of closed cracks is one of the most challenging problems in ultrasonic testing. Here, we propose a novel closed-crack imaging technique combining ultrafast phased-array with pump excitation. The pump excitation with kHz frequency can effectively induce the crack opening/closing behaviors since it can generate a large displacement of 1000 nm order. At the same time, ultrafast phased-array imaging, i.e. plane wave imaging, with MHz frequency stroboscopically captures the high-speed crack dynamics induced by pump excitation. We successfully proved the concept in a closed fatigue crack specimen.

The global air pollution is constantly increasing and causing negative effects on human health such as respiratory, cardiovascular diseases and cancers. Recently, pollution in Hanoi has become increasingly worse, especially when PM2.5 concentration is always at high level. Thus, PM2.5 prediction is of more urgency to issue early forecasts. Depending on air data including meteorological indicators and air pollution indicators collected in Hanoi, we have proposed a new characteristic extraction method that gave better results when uing the same algorithm compared to those of old methods. XGBoost algorithm was applied to predict the concentration of PM2.5 and the test showed that the accuracy of this algorithm is higher than that of other data mining algorithms while the training time is significantly lower.

Sidelink optimizations for layer-3 based IoT Relaying in 5G NR
Authors: narayanan Subin , Tsolkas Dimitris , Passas Nikos , Höglund Andreas , Liberg Olof
Published: December 2021

The effective support of 5G-Internet of Things (IoT) requires cellular service in deep coverage areas while providing long battery life for IoT devices which perform infrequent small data transmission towards the base station. Relaying is a promising solution to extend the coverage while at the same time meeting the battery life requirements of the IoT devices. Considering this, we analyze the suitability of layer-3 relaying over the 3GPP Release 16 NR-PC5 interface to support massive IoT applications. More precisely, we study the unicast connection establishment mechanism over the NR PC5 interface in a partial coverage scenario. Further, a set of optimizations on the Release 16 NR-PC5 procedure to effectively support massive IoT applications are proposed and analyzed. The obtained performance evaluation results which are presented in terms of data success probability, device power consumption, and signaling overhead, quantify how effectively the Release 16 NR-PC5 interface can support the requirement of IoT in the 5G and beyond era. The proposed sidelink small data transmission and frame-level access provides the largest gain overall and can reduce the device power consumption by an average of 68%, and signaling overhead by 15% while maintaining a data success probability of more than 90% in an IMT-2020 defined IoT traffic scenario.

Published: December 2021

Epilepsy affect almost 1% of the worldwide population. An early diagnosis of seizure types is a

crucial patient-dependent step for the treatment selection process. The selection of the proper treatment

relies on the correct identification of the seizure type. As such, identifying the seizure type has the

biggest immediate influence on therapy than the seizure detection, reducing the neurologist’s efforts

when reading and detecting seizures in EEG recordings. Most of the existing seizure detection and

classification methods are conceptualized following the patient-dependent schema thus fail to perform

well with unknown cases. Our work focuses on patient-independent schema for seizure type classification

and pays more attention to the explainability of the underlying attention mechanism of our method.

Using a channel-wise attention mechanism, a quantification of the EEG channels contribution is enabled.

Therefore, results become more interpretable and a visualization of brain lobes contribution by seizure

types is allowed. We evaluate our model for seizure detection and type classification on CHB-MIT and

the recently released TUH EEG Seizure, respectively. Our model is able to classify 8 seizure types with

an accuracy of 98.41%, directly from raw EEG data without any preprocessing. A case study showed a

high correlation between the neurological baselines and the interpretable results of our model. 
Il socialismo liberale: Carlo Rosselli
Authors: Ghiandelli Enno
Published: December 2021

In order to investigate issues somehow neglected, the paper tries to carefully outline both the economic and institutional aspect and the origins and development of the Florentine anti-fascist thought. Much has been written about Carlo Rosselli's liberal socialism; still interpretations are often based more on subjective views than on in-depth studies, and this is especially true when it is the current political situation which tries to interpret Rosselli’s thought. Several scholars approached Carlo Rosselli’s thought assuming that the adjective ‘liberal’ can be translated as ‘liberalistic’, that the noun ‘socialist’ can be replaced with ‘welfare’ (of a moderate sort in addition), and finally that the State he theorized proves little interventionist in social and economic life; but this does not seem to be a correct interpretative key.

Modern linguistics is characterized by anthropocentrism, in the center of its research attention are questions about a person based on his integrity and exclusivity. This article is devoted to the study of the verbalization of such basic emotions as fear and horror. The subject of the research is the features of the basic emotions of fear and horror in the modern Russian language. The work was carried out on the basis of the material of the National Corpus of the Russian Language. The purpose of the work is to identify and define the features of the verbalization of emotions fear and horror in the modern Russian language. The relevance of the study is due to the inevitable dependence of every sphere of a person's life on his emotional state. Despite the extensive study of emotions by psychology, psycholinguistics, linguistics, a number of questions remain in this problem. The materials of the Russian National Corpus provide great opportunities for studying the verbalization of the emotions of a native speaker of the Russian language in various genres and styles, which allows reaching a new level of research. The peculiarity of the study of emotions is found in the variety of linguistic means of their expression, which include the appropriate vocabulary, phraseological constructions and a certain compatibility. The novelty of the research lies in the fact that the comparative analysis of the verbalization of the basic emotions of fear and horror is carried out on the basis of the material of the National Corpus of the Russian language. In the course of the work, the following methods were used: descriptive, involving the analysis of both theoretical and empirical material, generalization and interpretation of the results obtained; component analysis; introspection method; comparative and comparative and statistical methods. The practical significance of the study is due to the fact that its materials and conclusions can be used in university courses in lexicology, lexicography, psycholinguistics.
Paremiological representation of concept “Word” (in the English, Russian and Uzbek Languages)
Authors: Galieva Margarita Rafaelovna
Published: December 2021

The aim of this article is to study the national-cultural specifics of the concept Word and peculiarities of its verbalization on the material of paremiological units of the English, Russian and Uzbek languages. The scientific novelty of the research is determined by the identification of the specific features of the verbalization of the image-bearing and evaluative components of the concept Word in the languages under consideration. The image-bearing component of the concept Word in each language is represented by metaphorical nominations, which, according to the way of reflecting cognitive thinking, are subdivided into objective, natural, ornithological and anthropomorphic. The evaluative component of the concept Word is characterized by the accentuation of evaluative component, which expressing cognitive-conceptual signs of a positive and negative character, forms the conceptual space of axiological dominants, a set of which forms a certain conceptosphere topical for a particular culture and gives opportunity of revealing the national identity of each linguoculture under consideration. As a result of the comparative and cross-cultural analysis of cognitive-conceptual features identified at the level of proverbial units, universal and national-specific features of the verbalization of the concept Word were determined. National and cultural specifics of the concept Word is determined by the peculiarities of the national perception of this concept by the representatives of the studied linguocultures in accordance with their axiological dominants. Analyzed units were compared according to the followings: a) metaphorical nominations and cognitive-conceptual features (image-bearing, evaluative) expressed by them; b) according to the degree of representation of cognitive-conceptual features in each of the languages under consideration; c) by the thematic relevance of the identified cognitive-conceptual features; d) on the basis of the presence/absence of cognitive-conceptual features in a particular linguistic culture.
Application of multiphase flow and droplet separation theory in modeling cough droplets contamination range to mitigate COVID-19 transmission: Do not stand too close to me!
Authors:   Petroleum Engineering Dept., College of Engineering and Petroleum, Kuwait University, Kuwait, M. Al-Safran Eissa
Published: December 2021

On March 11, 2020, the World Health Organization (WHO) declared that COVID-19 is a pandemic, warning the world of a health catastrophe and social, economic, and political disruptions. According to WHO, COVID-19 is transmitted by the transport of respiratory droplets generated by a violent respiratory event such as sneeze and cough directly to susceptible persons, or indirectly through surfaces. The aim of this study is to propose simple physical and mathematical models based on two-phase flow dynamics and droplet separation theory. The proposed mathematical model predicts the contamination range of ejected cough droplets, estimating the safe person-to-person social distance. As a result, the proposed simple model predicted a contamination range of 2.3 m for a male adult. In addition, to understand the behavior of ejected cough droplets, a sensitivity analysis is carried out to investigate the effect on contamination range of cough air flowrate, i.e., body/lung size, droplet size, and droplet drag coefficient. It is found that as the body/lung size decreases, i.e., lower cough flow rate, contamination range decreases, resulting in 1.9 m for an adult female, and 1.4 m for a child. In addition, the model predictions show an appreciable effect of droplet size, and droplet drag coefficient on cough contamination range. In particular, the effect of droplet drag coefficient is of interest, because of its relationship to ambient conditions such as temperature and relative humidity, in which both affect ambient air viscosity, and thus drag coefficient. This is important in investigating the contamination range and person-to-person social-distance as climate changes.

Published: December 2021

We report here a combination of transition metal-based ternary sodium magnate layered cathodes with the compositions of Na0.8Fe0.4Mn0.3Co0.2O2, Na0.8Fe0.4Mn0.3Ni0.2O2, Na0.8Fe0.4Mn0.3V0.2O2, Na0.8Fe0.4Mn0.3Ti0.2O2, in order to elucidate the precise metal contents for the superb performing positive electrode. Based on their stoichiometry, the transition metal combination of Na0.8Fe0.4Mn0.3Co0.2O2, O3-type crystal structure with R3m space group possess superior electrochemical behavior under the test of sodium-ion battery. When the charge-discharge capacities in the range of 2.0-4.2 V at 0.1 C are measured, it shows the comparatively higher performance of the first and second charge capacities of 162 mAhg-1, 170 mAhg-1 and discharge capacities of 157 mAhg-1, 154 mAhg-1, respectively. Moreover, it was remarkable to observe that the increasing/decreasing Co constituent substantially affects the performance and stability, but using the ternary combination in cathodes, a substantial reduction of Jahn-Teller distortion and increased biphasic characteristics were observed. The as-synthesized samples were characterized by FE-SEM, XRD, charge-discharge curve, EIS and cyclic voltammograms.

Published: December 2021

In developing countries, little information is available about solid-waste characteristics, determinants for adoption and performance-evaluation of municipal-waste management systems in Municipals. This study aimed: to characterize the municipal solid-wastes, collection, dumping and evaluate the efficiency and reliability of Municipal solid-waste management system. A total of 200 households were randomly sampled and interviewed. Data was analysed using Binary-Logistic Regression model to determine factors influencing collection and dumping of solid wastes. Results showed that biodegradable/organic wastes comprise a major fraction of solid-wastes produced. Factors that influenced solid-waste collection and dumping included: household-age, unavailability of solid-waste containers, inadequate collection/dumping space and weak legal-enforcement against poor-dumping. The waste system is constrained by inadequate transport facilities, inadequate space for temporal dumping; and lack of legal enforcement in matters of solid-waste poor handling. These have made the systems ineffective and unreliable. This study recommends involvement of all stakeholders in innovative approaches to uphold sustainable municipal sanity.

Flash C-H Chlorination of Ethylene Carbonate Using a New Photoflow Setup
Authors: Kasakado Takayoshi , Fukuyama Takahide , Nakagawa Tomohiro , Taguchi Shinji , Ryu Ilhyong

We report flash C-H chlorination of ethylene carbonate, which gives chloroethylene carbonate, a precursor to ethylene carbonate.  A novel photoflow setup designed for a gas-liquid biphasic reaction turned out to be useful for the direct use of chlorine gas in flow.  The setup employed sloped channels so as to make the liquid phase thinner, ensuring high surface to volume ratio.  When ethylene carbonate was introduced to the reactor, the residence time was measured to be 15 or 30 sec, depending on the slope of the reactor to be 15 or 5 °C, respectively.  Such short time exposition sufficed the photo C-H chlorination.  The partial irradiation of the flow channels sufficed for the C-H chlorination, which is consistent with the requirement of photoirradiation for the purpose of radical initiation. We also found that the contaminated water negatively influenced the performance of C-H chlorination.  The 100% selectivity for single chlorination required the low conversion of ethylene carbonate such as 9%, which was controlled by limited introduction of chlorine gas.  At a higher conversion of ethylene carbonate such as 63%, the selectivity for mono-chlorinated ethylene carbonate over di-chlorinated ethylene carbonate was 86%.  We found that the contaminated water negatively influenced the performance of the C-H chlorination.
Relationship between corrosion and nanoscale friction on a metallic glass
Authors: Ma Haoran , Bennewitz Roland
Published: December 2021

Metallic glasses are promising materials for micro-devices, where corrosion and friction limit their effectiveness and durability. We investigated nanoscale friction on a metallic glass in corrosive solutions after different immersion times using atomic force microscopy to elucidate the influence of corrosion on nanoscale friction. The evolution of friction upon repeated scanning cycles on the corroded surfaces reveals a bilayer surface oxide film, where the outer layer is removed by the scanning tip. Friction and adhesion after different immersion times in different solutions allow to compare the physicochemical processes of surface dissolution at the interfaces of the two layers. The findings contribute to the understanding of mechanical contacts with metallic glasses in corrosive conditions by exploring the interrelation of microscopic corrosion mechanisms and nanoscale friction.

XVI. yüzyıldan itibaren Kafkasya’yı hâkimiyeti altına almaya yönelik bir politika izlemeye başlayan ve 1864 yılında Kuzey Kafkasya’yı işgal eden Rusya, bölgede yaşayan Çerkesleri Osmanlı Devleti topraklarına göç etmeye zorlamıştır. 1850’lerde başlayan Çerkes göçleri 1862-1865 yılları arasında yoğunlaşmış ve 1860’ların sonuna kadar devam etmiştir. Sürekli isyanların yaşandığı Balkanlar’da Çerkeslerin savaşçılığından yararlanmak ve Müslüman nüfusunu arttırmak isteyen Osmanlı Devleti, bu dönemde 400.000’den fazla Çerkes’i Rumeli’ye yerleştirmiştir. 9.000-11.000 civarında Çerkes de Kosova’ya iskân edilmiştir. Kosova’ya gelen Çerkesler burada köyler kurmuşlardır. Yeni vatanlarında tarım ve hayvancılıkla uğraşmaya başlamışlardır. Ancak, Kosova’ya yerleştirilen Çerkeslerin büyük bir kısmı burada kalıcı olmamıştır. Avrupa devletlerinin 23 Aralık 1876’da toplanan İstanbul Konferansı’nda Çerkeslerin Balkanlar’ı terk etmesini istemesi ve 1877-1878 Osmanlı-Rus Savaşı, Kosova’da yaşayan Çerkeslerin bir kısmının Anadolu’ya ve Ortadoğu’ya göç etmesine sebep olmuştur. Kosova’da geriye kalan Çerkeslerin büyük çoğunluğu da Balkan Savaşları sırasında ve sonrasında bölgeden ayrılmıştır.

Bu çalışmada, 1864-1865 yıllarında Kosova’ya yapılan Çerkes göçü ve iskânını hazırlayan gelişmeler, göç ve iskân sırasında karşılaşılan sorunlar ve bu sorunların çözümü için izlenen politikalar ele alınmıştır.

Published: December 2021

The use of instrumental diagnosis methods is a way to form an individual strategy of rehabilitation treatment and effectiveness monitoring. However, there is a lack of methods for objective assessment of the muscle groups’ functional state in both patients with dorsopathy and healthy individuals, as well as incorrect use of existing diagnostic tools due to the lack of the regulatory framework. The subjects had no complaints on low back pain, and there was no history of pain episodes associated with spinal pathology. All the volunteers were comparable in height and weight before being included in the study. The study was conducted in accordance with the terms of the Helsinki Declaration, all subjects signed an informed consent before the start of diagnostic activities.
Aim. To determine the normative values of the strength of the flexor muscle group (FM) and extensor muscles (EM) of the lumbosacral spine and to establish the ratio of the obtained results to the automatic hardware norm.
Material and methods. The present clinical study included 22 healthy volunteers aged 23 to 61 years (the average age was 38.4±12.8 years), including 14 women (63.6%) and 8 men (36.4%).
Results and discussion. The results obtained demonstrate that the real normative indicators for MS and MR in healthy individuals can vary in the range from the hardware norm value calculated automatically by the device to a value of 20% lower. Exceeding this parameter is not a pathological deviation. When assessing the muscle strength, a decrease in this indicator is of physiological and clinical significance, since it reflects the dysfunction of this area and is a predictor of the pain syndrome chronicity.
Conclusion. The standard values findings allow us to assess correctly the initial clinical condition and use this instrumental method with biofeedback for patients with degenerative spinal lesion and non-specific pain in the lumbosacral region and patients who have undergone spinal surgery to develop individual rehabilitation programs. As a further prospect for the use of diagnostic systems with biofeedback, it is suggested that the examination plan should include the determination of the ratio of the FM strength to the EM strength, as well as the strength of the muscles involved in the lateral slopes of the trunk.

En los sistemas de producción de café la adopción de las tecnologías y prácticas agronómicas generadas por la investigación científica reduce la incertidumbre y el riesgo inherente de la actividad; contribuye significativamente al cambio técnico permitiendo incrementos sostenidos en la productividad, con menores costos unitarios de producción, logrando mayores ingresos brutos y aumentando el margen neto que determina la rentabilidad para la familia cafetera. En el cultivo de café, dada su condición de perenne, las decisiones que se tomen para definir el sistema de producción tienen implicaciones de largo plazo y deben obedecer a una adecuada planificación, pues corregir decisiones erradas tendría un alto costo para el caficultor. La estrategia implementada desde 2016 por la Gerencia Técnica de la Federación Nacional de Cafeteros “Más Agronomía, Más productividad, Más Calidad” tiene por objetivo hacer énfasis en la definición de un sistema de producción resiliente y la realización correcta y oportuna de prácticas agronómicas fundamentales, para garantizar niveles adecuados de productividad y por esa vía lograr rentabilidad de la finca cafetera. Las prácticas agronómicas que se deben llevar a cabo con rigurosidad son: Sembrar variedades mejoradas con resistencia durable a la roya; utilizar colinos de café de origen conocido; sembrar o renovar los cultivos en las épocas correctas; establecer la densidad de siembra óptima; definir los ciclos de renovación para mantener los cultivos jóvenes; conocer la acidez del suelo y corregirla para el cultivo de café; nutrir apropiadamente los cultivos; manejar la luminosidad del cultivo. La productividad implica la toma de decisiones correctas y oportunas por parte del caficultor para realizar inversiones en insumos y en labores, de manera que impacten la respuesta biológica del cultivo, mejoren la valoración del café pergamino seco que se comercializa, y afecten de la menor manera al medioambiente. Es por esto que, es importante tener conocimiento de la eficiencia económica de los costos asociados a las prácticas agronómicas. El propósito fundamental de este libro es difundir las ventajas económicas y agronómicas de las tecnologías mencionadas, mostrando su viabilidad técnica y económica con el objetivo de mejorar el desempeño económico de las fincas cafeteras, elevar su competitividad y, por lo tanto, contribuir al desarrollo rural de las regiones cafeteras colombianas.

On the Identification of Individual Gravitational-wave Image Types of a Lensed System Using Higher-order Modes

Published: December 2021

Similarly to light, gravitational waves can be gravitationally lensed as they propagate near massive astrophysical objects such as galaxies, stars, or black holes. In recent years, forecasts have suggested a reasonable chance of strong gravitational-wave lensing detections with the LIGO–Virgo–KAGRA detector network at design sensitivity. As a consequence, methods to analyze lensed detections have seen rapid development. However, the impact of higher-order modes on the lensing analyses is still under investigation. In this work, we show that the presence of higher-order modes enables the identification of individual image types for the observed gravitational-wave events when two lensed images are detected, which would lead to unambiguous confirmation of lensing. In addition, we show that higher-order mode content can be analyzed more accurately with strongly lensed gravitational-wave events.
