Published: December 2022

Background. Biliary cystadenomas and cystadenocarcinomas are rare cystic tumors of the liver. Complicated differential diagnostics for simple cysts often leads to errors in surveillance of patients with these tumors. Cystadenoma and cystadenocarcinoma should be suspected upon detection of single or multilocular cystic neoplasms of the liver with septa and blood flow loci  in the cyst wall, especially in middle-aged women. The localization of the tumor is critical. The most common localization is segment IV of the liver. Urgent intraoperative biopsy is required to determine the extent of surgery.

Case description. Clinical observations with analysis of the examination and treatment data of two female patients aged 38 and 56 were presented. Both clinical observations illustrate the underestimation of the preoperative examination data that served as a ground for diagnosis of liver cysts with inadequate extent of surgery. In the first case, the resection was incomplete, and, as such, the biliary cystadenoma recurred in the resection area, the capsule of the neoplasm was ruptured and an encysted fluid collection was formed. In the second case, lack of histological examination of the excised neoplasm, due to confidence in its morphological verification as a cyst, resulted in cystadenoma recurrence in the resection zone with metastasis to the contralateral lobe of the liver.

Conclusion. Hepatic cystadenomas and cystadenocarcinomas are often misdiagnosed as simple cysts. These tumors should be suspected in central localization of the tumor in the liver, especially in young women. The clinical and instrumental symptomatology and radiological semiotics of the disease require careful evaluation. The recurrence of a cystic lesion in the resection zone in a patient previously operated for a hepatic cyst serves as an additional signal for detecting biliary cystadenoma. Rational strategy for surgical management of cystic liver lesions should include hepatectomy within healthy tissues (both anatomical and atypical) with mandatory intraoperative ultrasound and urgent histological examinations.
Occipital condyle fracture caused by minor head trauma
Authors: Hayashi Seiya , Umakoshi Michiari , Yunoki Masatoshi , Hirashita Koji
Published: December 2022

Background:

Occipital condyle fractures (OCF) are commonly identified in patients suffering from severe craniocerebral trauma. Here, we present a 57-year-old male whose computed tomography (CT)-documented atlanto-occipital dislocation (AOD), due to just minor trauma was successfully managed with bracing alone.

Case Description:

A 57-year-old male presented with the right upper neck pain following a motor vehicle accident. The screening cervical CT scan revealed a fracture of the right occipital condyle, while the subsequent dynamic X-rays showed no instability or AOD. The patient was treated with a hard cervical collar, and over the next 6 months, remained asymptomatic. The 6-month repeat craniocervical CT scan additionally confirmed spontaneous fusion at the fracture site.

Conclusion:

Patients who have sustained even mild craniocervical trauma may develop AOD attributed to an OCF. It is critical to screen these patients early with CT and X-ray studies so they can be successfully managed with bracing alone, and avoid the need for surgery to address the delayed onset of instability.
Primary midbrain germinoma relapse-free for 5 years: A case report
Authors: Oshima Akito , Kimura Toshikazu , Akabane Atsuya , Inoue Tomohiro
Published: December 2022

Background:

The biology and clinical course of intracranial germinomas differ as per their location of occurrence. Germinoma of the primary midbrain is particularly rare, and its clinical features, treatment strategies, and long-term prognosis remain uncertain.

Case Description:

A 39-year-old man who had been diagnosed with midbrain germinoma by open biopsy through the occipital transtentorial approach had undergone chemoradiotherapy and achieved 5 years with no recurrence.

Conclusion:

Germinomas should be considered as a differential diagnosis for adolescents and young adult men with mesencephalic tumors, and reliable sampling followed by chemoradiotherapy must be performed.

Published: December 2022

The selective functionalization of non-activated C(sp3)—H bonds is a major challenge in chemistry. Here, we have developed an [Au]-catalyzed C(sp3)-H activation of common 1 bromoalkynes into a library of diverse 3D-scaffolds. The reaction was shown to proceed via an unknown before mechanism: a concerted [1,5]-H shift / C—C bond formation involving a gold-stabilized vinylcation-like transition state. The most salient feature of this methodology is the ability to functionalize in a predictable way non-activated C(sp3)—H bonds without any sort of electronic, geometric, or conformational bias.
Modulating the lifetime of DNA motifs using visible light and small molecules
Authors: Wimberger Laura , Rizzuto Felix , Beves Jonathon
Published: December 2022

Here we regulate the formation of dissipative assemblies built from DNA using a merocyanine photoacid that responds to visible light. The operation of our system, and the relative distribution of species within it, are controlled by irradiation time, initial pH value, and the concentration of a small molecule binder that inhibits the reaction cycle. This approach is modular, does not require DNA modification, and can be used for several DNA sequences and lengths. Our system design allows for waste-free control of dissipative DNA nanotechnology, towards the generation of non-equilibrium, life-like nanodevices.

Authors: Ribeiro José Carlos , Matos Mariana
Published: December 2022

Este trabalho visa discutir os elementos que permeiam as performances de influenciadoras de moda plus size na plataforma digital Instagram. Para tal, aplica conceitos da Teoria Dramatúrgica proposta por Erving Goffman, levando em consideração tanto a complexidade da relação entre a moda e os corpos gordos quanto as particularidades que envolvem as interações sociais ocorridas em ambientes digitais. Foi realizada a observação não participante com três dos principais perfis de influenciadoras digitais de moda plus size brasileiras no Instagram: Thais Carla, Letticia Munniz e Ju Romano. A partir do exame dos dados, duas categorias de análise foram propostas: (1) A imagem pública que compõe as performances de influenciadoras digitais de moda plus size no Instagram e (2) As dinâmicas interacionais associadas às performances de influenciadoras digitais de moda plus size com suas seguidoras no Instagram. Concluímos que, por meio das performances exercidas, as influenciadoras transmitem para as suas seguidoras uma imagem de autoaceitação corporal, adotam estratégias que gerenciam suas interações com o intuito de preservar suas imagens públicas pessoais, mantêm a credibilidade e o sentido de representatividade perante as seguidoras e usam a moda como instrumento de ruptura de paradigmas opressores em relação ao corpo gordo.

Authors: Sousa Bárbara Lethicya Silva , Cantanhede Severina Coelho da Silva , Cantanhede Leonardo Baltazar , Sousa Diana Araujo de
Published: December 2022

Os Textos de Divulgação Científica (TDC) divulgam a ciência de forma clara e acessível para o público em geral, permitindo a articulação dos saberes científicos com a sociedade em geral. Assim, propostas de inclusão de TDC no ambiente escolar têm se destacado como um caminho viável para atender diferentes necessidades de aprendizagem recorrentes na Educação Básica. Neste trabalho, investigamos o potencial do uso de TDC no Ensino Médio como um recurso didático para o ensino da Química. Para tanto, elaboramos e aplicamos uma estratégia didática pautada no uso do TDC da Revista Ciência Hoje, seção O Leitor Pergunta A sacola de amido pode ser uma solução menos danosa ao ambiente, do que as sacolas tradicionais? (Edição 305, julho/2013, nº. 53). A escolha do TDC foi orientada, considerando a relevância do assunto e a discussão da pergunta, como forma de facilitar o estudo do conteúdo de polímeros. A análise e a viabilidade da utilização dos TDC foram realizadas pelo uso de questionário no formato Likert, além de questões discursivas. O somatório dos índices positivos de análise apresentou valor próximo a 90%. Sob o ponto de vista pedagógico, o TDC possibilitou debates a partir da sistematização dos conhecimentos científicos associados à discussão do conteúdo polímeros, integrando problemáticas sociais, como a poluição ambiental, descarte, reciclagem, plásticos e lixo que estão presentes nas discussões do conteúdo polímeros, contribuindo para o exercício da cidadania dos estudantes, a partir de uma maior consciência ambiental sob a utilização de sacolas plásticas.
E A PARTE DA HISTÓRIA QUE NÃO É CONTADA? REFLEXÕES FEMINISTAS SOBRE A HISTÓRIA DA CIÊNCIA
Authors: Lima Ana Luíza , Soares Márlon Herbert Flora Barbosa
Published: December 2022

Compreendendo a importância das discussões de gênero e das mulheres na ciência, o presente artigo propõe, a partir de um olhar feminista, apresentar a história de algumas cientistas, em especial as primeiras mulheres aceitas nas universidades ocidentais. O presente estudo possui um caráter teórico e tem por objetivo analisar alguns aspectos e períodos da história da construção científica, como forma de evidenciar o processo de exclusão e invisibilização das cientistas nos períodos em destaque. É salutar destacar que a escolha pela abordagem feminista para a análise histórica da ciência se deu, especialmente, pelo caráter político, social e interseccional dos movimentos feministas. A partir do exposto, foi possível constatar a contradição nos ideais de neutralidade, objetividade e isenção de posicionamentos políticos/religiosos, ao qual a construção científica se baseou, em especial no que cerne as discussões de gênero. Diante de uma construção científica que invisibilizou, deslegitimou e excluiu as cientistas, além de terem tido seus saberes apropriados, a ciência ainda hoje permanece dentro de parâmetros misóginos e segregadores. Sendo assim, essa pesquisa propõe a urgência de reflexões e discussões de gênero nas comunidades científicas.
Shoulder abduction strength is correlated with acromiohumeral distance in patients with acute subacromial impingement syndrome symptoms but not with supraspinatus tendon thickness regardless of disease stage
Authors: Yesilyaprak Sevgi Sevi , Karabay Damla , Turksan Halime Ezgi , Erduran Mehmet
Published: December 2022

We aimed to investigate the relationships of isometric and eccentric shoulder abduction strength with acromiohumeral distance and supraspinatus tendon thickness based on the disease stage in patients with subacromial impingement syndrome. Eighty-two patients with subacromial impingement syndrome were assessed. Acromiohumeral distance and supraspinatus tendon thickness were measured using ultrasonography. Isometric and eccentric shoulder abduction strength were measured with a hand-held dynamometer. Spearman’s correlation coefficients were calculated. Isometric (rho = 0.428, p=.021) and eccentric (rho = 0.487, p=.007) shoulder abduction strength showed moderate correlations with acromiohumeral distance in patients with acute symptoms (n = 29). There was no relationship between acromiohumeral distance and abduction strength in patients with chronic symptoms (n = 53) (p>.050). Supraspinatus tendon thickness showed no significant correlation with abduction strength (p>.050). These findings suggest that the relationship between acromiohumeral distance and abduction strength differs according to disease stage. However, supraspinatus tendon thickness was not correlated with abduction strength regardless of disease stage. In patients with acute subacromial impingement syndrome symptoms increasing shoulder abduction strength may be a potential strategy to improve acromiohumeral distance.
"more cars and fewer hen houses": New Zealand interior and landscape architectures of the 1960s
Authors: McCarthy Christine
Published: December 2022

In New Zealand most extant dolls' houses from the second half of the twentieth century are home-made. The venture by the Auckland firm Jomax into mass-producing a single-storey dolls' house in the mid-sixties was unusual. This venture may have been spurred on by the traditional two-storey dolls' houses being produced by the New Zealand Tri-ang factory, also in Auckland. The Jomax "Little Princess" dolls' house does not, like the New Zealand Tri-ang houses, reflect a UK heritage, but is clearly a New Zealand house similar in form to many being built and published in the 1960s. Jomax also made sets of modern-style furniture suitable for fitting out its four rooms and a hallway. The paper examines the interiors of this New Zealand-designed house and compares them with those of UK (Tri-ang) and East German (Gottschalk) toy houses of the same vintage. The comparison explores the interiors, with their obvious differences and some similarities, and asks whether they reflect the full-scale versions of the time, or whether they were to some extent aspirational.

NZSS 1900 Model Building By-law: a planned evolution
Authors: Isaacs Nigel
Published: December 2022

Twenty-five years after its publication, NZSS 95:1935 "Model Building By-law" was starting to show its age. The 1961 City Engineers conference requested it be reorganised to put general requirements first and design requirements later. The NZ Standards Institute's (NZSI) Bylaw Sectional Committee thought this a good idea, although to avoid confusion changed the designation of the new series to NZSS 1900. From late 1963 to mid-1964, NZSS 95 was reissued as NZSS 1900. The 14 parts of NZSS 95 became 11 chapters of NZSS 1900, initially by reprinting with new covers. Over the next 20 years the chapters were modified, revised, split, or amalgamated.On 1 April 1966 NZSI became the Standards Association of New Zealand (SANZ), and 'New Zealand Standard Specifications" (NZSS) became "New Zealand Standards" (NZS). By late 1966 the revision and publication of NZS 1900 was nearly complete. For the future a five yearly review cycle was planned. However, storm clouds were ahead. NZS 1900 had a mixture of: legal requirements; design and construction requirements; quantitative requirements; and codes of practice. The resultant documents were considered to be hard to: use; inspect on site; and revise. In late 1969 the Standards Council was looking forward to a revision separating requirements (fixed, unchanging and rarely alternative) from solutions (changing as technology develops, often with alternatives). The "means of compliance" could be provided for the majority of users, while other solutions were available as desired or required. This set the scene for the Building Act 1991 and New Zealand Building Code.The paper reviews the development of NZS 1900, exploring the similarities and differences to NZSS 95. As an example of the process, the evolution of the requirement for windows for ventilation will be examined.
Is the Get-passive Really that Adversative?
Authors: Coto Villalibre Eduardo
Published: December 2022

The characteristics commonly attributed to central get-passives in the relevant literature include the possibility of taking an overtly expressed agent by-phrase, a dynamic meaning conveyed by the lexical verb, an animate and human referent who is at the same time responsible for the action expressed in the clause, and an adversative semantic implication of the past participle. This paper focuses on one of the abovementioned features: the semantic implication of get-passives, that is, whether the event described in the clause is beneficial or favorable for the subject (get awarded, get elected, get promoted), adversative or unfavorable for the subject (get arrested, get killed, get shot), or semantically neutral (get printed, get sent, get written). Data collected from a corpus-based analysis of the spoken British English component and other spoken ESL components of the International Corpus of English (ICE) will be deployed to argue against those claims which define the get-passive as a predominantly negative or adversative construction in Present-Day English.

Published: December 2022

Dengan berkembangnya teknologi informasi secara signifikan, keamanan data merupakan aspek penting dalam sistem teknologi informasi. Terutama didalam mengamankan distribusi dokumen dalam suatu jaringan komputer. Citra digital merupakan dokumen berbasis gambar yang sering tidak dipedulikan dampak negatifnya bila dimanfaatkan oleh orang yang tidak bertanggung jawab. Banyak terjadi manipulasi gambar dengan bentuk yang tidak berkenan dan pemilik gambar aslinya merasa dirugikan karena gambar yang telah dimanipulasi telah menunjukkan gambar yang buruk baginya. Untuk itu dibutuhkan suatu sistem yang bisa memberikan solusi untuk masalah tersebut. Pada penelitian ini akan dibahas suatu sistem kriptografi untuk mengamankan data citra menggunakan algoritma ElGamal. Citra yang dienkripsi yaitu citra RGB 24 bit dengan format JPG/JPEG. Hasil dari sistem ini adalah citra RGB 24 bit yang tidak dapat dikenali lagi (sudah teracak) dari citra aslinya.  Dengan adanya sistem ini dapat mengamankan data gambar dari pihak-pihak yang tidak berkepentingan, sehingga hanya pihak-pihak tertentu saja yang dapat melihat bentuk asli dari gambar yang disimpan atau yang didistribusikan.

Dynamic Communities: Plotting a New Course
Authors: J Hafer Andy
Published: December 2022

Dynamic Communities was a company that forms and administers Software User Groups. Each group had a thriving membership which shared knowledge and information among each constituent in the community. Active participation by employees of member companies led to stronger competency in the software and eventually higher return on software investment for their employer. Programs and features of membership in a User Group ranged from online aspects (such as interactive discussion forums and downloadable content libraries) to in-person events (including training, certifications, and large-scale conferences). Companies joined in membership, paying an annual membership fee, to allow its employees access to the programs and features of the community.

Through the first twelve years of existence, Dynamic Communities counted on double-digit growth in revenue from membership fees. However, it flattened. As technology evolved and social media became more pervasive, it had become easier and easier for individuals to replicate many of the learning features that made membership in a Dynamic Communities User Group exclusive. Persons found highly specialized information just by working the search engines. No longer was Dynamic Communities able to simply put online content behind a firewall and expect members to pay to access it.

Revenue from membership fees made up about 19% of the company’s annual revenue but was eroding. Dynamic Communities executive team was faced with a dilemma of trying to revise its membership model in an environment of significant change while still maintaining its revenue sources. This case challenges the reader to assess price and product mix strategies.

“I DREAM OF BEING WITH MY COLLEAGUES IN THE SOVIET UNION”: THE PROBLEM OF REPATRIATION AMONG ÉMIGRÉ ARTISTS IN FRANCE (1920S-1930S)
Authors:   Russian State University for the Humanities, Krasnoslobodtsev Konstantin V.
Published: December 2022

In the first years after the revolution, the relations between the intelligentsia and the young Soviet government were more complicated than those of other social groups. Among the emigrant artists, there is a whole range of models of relations with the Bolsheviks: from military emigration, irreconcilable opponents of the “Sovdepia” through doubters who kept neutrality, to fierce supporters. The artists had a large “period of reflection” during which it is necessary to determine their attitude to the new government. However, it was possible to maintain the status of “ambivalent emigration” only for a short time. The intelligentsia did not have a special amnesty to return, but the Soviet government tried to return cultural and artistic figures. They were treated not with the tools of mass agitation, but with personal influence, sometimes with the help of relatives who remained in Russia. In relation to artists, arguments were used appealing to their creative self-realization, the demand and “necessity” of their art at home. Features of repatriation among Russian emigrant artists in France are considered by the author on the basis of archival documents.
“HISTORY OF THE PEOPLES OF THE USSR” BY YU.V. GAUTHIER AT MGIAI (1936/1937 ACADEMIC YEAR)
Authors:   Russian State University for the Humanities, Taratorkin Phillip G.
Published: December 2022

The article considers in historiographical context the main problems, topics and subjects of the unpublished lecture course “The History of the Peoples of the USSR”, delivered by Academician Yu.V. Gautier at the Moscow State Historical and Archival Institute (MGIAI) in the academic year 1936/37. In the lecture course are seen those priorities and benchmarks which are due to the specifics of the historiographical process of those years, but at the same time are evident many fundamental principles and foundations of understanding of the Russian historical process, typical for historians of the “old school”, forced to adapt their lives to the circumstances of the new historiographical life.
THE NOTIONS ABOUT THE FEAR OF GOD IN THE “TALE OF BYGONE YEARS” AND THE “INSTRUCTION” OF VLADIMIR MONOMAKH
Authors:   Russian State University for the Humanities, Borisova Svetlana A.
Published: December 2022

The category of the Fear of God has changed over time despite its apparent immutability. The article discusses the semantics of the concept of the Fear of God and the notions associated with it, based on the “Tale of Bygone Years” and Vladimir Monomakh’s “Instruction”. The author of the article analyzes all mentions of “the Fear of God” in the selected sources, paying special attention to the context of the expression. The research has shown that, to describe the Fear of God, the chronicler mainly uses quotations, especially from sacred texts. With their help, the chronicler conveys his ideas about the studied category. The analysis of the sources reveals that the Fear of God should not be considered as an emotion, but as a long-term state or feeling that positively influenced the person’s way of life. The Fear of God was the result of a conscious choice and the basis for the life of a pious Christian. In addition, the Fear of God was close to the states of awe and joy that emerge during worship. Particularly important for the chronicler was the connection between the Fear of God and the concept of wisdom, which was believed to spring from the former. The Fear of God was the basis of knowledge perceived as a process of understanding God
THE CAMPAIGN TO “CLEANSE” THE PARTY AND STATE APPARATUS IN THE SATIRICAL MAGAZINE “CROCODILE” (1929–1930)
Authors:   Russian State University for the Humanities, Yurganov Andrei L.
Published: December 2022

The article discusses the campaign to “purge” the party and state apparatus, which was planned in 1928 and carried out in 1929. That campaign was personally directed by Stalin, general secretary of the Central Committee of the VKP(b). The article studies the mechanism of adapting party decisions on “purges” with respect to propaganda in the satirical magazine Crocodile, which was published in huge circulations. Party decisions on paper are one thing; their implementation in images and symbols of Soviet daily life understandable to a mass audience is another. The campaign had one goal – to intimidate society and create conditions for the transition to a more mass repression, while abandoning the new economic policy. The fundamental differences between the purge of the party apparatus and the purge of the state apparatus are explored.

Aims: Several studies have been performed that compare the accuracy of Robotic-Assisted Total Knee Arthroplasty (RATKA) to conventional instrumentation as well as navigation to conventional instrumentation, yet there is a lack of studies comparing RATKA to navigation. The purpose of this study is to evaluate the accuracy of a contemporary image free navigation system for TKA in a cadaveric study using the same methodology as used previously to access the accuracy of a RATKA system and conventional instrumentation. Methods: Four orthopaedic surgeons performed bi-lateral TKA on 18 pelvis-to-toe cadaveric specimens without implantation using the BrainLab Knee3 navigation system. Preoperative and postoperative computed tomography (CT) scans were taken to access the resection accuracy of the navigation system relative to the planned alignment targets recorded intraoperatively. Results: The mean error in femoral coronal angle was 1.08° ± 0.87° compared to 1.39° ± 0.95° conventional and 0.63° ± 0.50° RATKA; the differences between navigation and RATKA were statistically significant. The mean error in the tibial coronal angle was 1.24° ± 1.13° compared to 1.65° ± 1.29° conventional and 0.93° ± 0.72° RATKA. The mean error in femoral flexion was 2.13° ± 1.87° compared to 3.27° ± 2.51° conventional and 1.21° ± 0.90° RATKA; the differences between navigation and manual and navigation and RATKA were statistically significant. The mean errors in the femoral rotation (navigation 1.30° ± 1.38°, conventional 1.00° ± 0.70°, RATKA 1.04° ± 0.81°) and tibial slope (navigation 1.89° ± 1.28°, conventional 1.63° ± 1.39°, RATKA 1.62° ± 1.13°) were similar between the groups. Conclusion: This study showed that for some metrics navigation improves resection accuracy compared to conventional instrumentation and RATKA further improves resection accuracy compared to CAS.
Accuracy Evaluation of Image-Based Virtual Fixtures in Robotic Laminectomy
Authors: Vossel Manuel , Theisgen Lukas , Radermacher Klaus , de la Fuente Matías
Published: December 2022

The accuracy of image-based computer assisted orthopedic surgery highly depends on the accuracy of the registration step as well as image acquisition, planning and tool calibration. In this paper the accuracy of those steps is evaluated exemplarily for a robotic laminectomy.

A high-resolution test bench was designed to compare the actual location of an object and the position to which the robotic system guides the surgical tool according to the image-based plan.

Depending on the distance between the patient reference array and the tool array, average accuracies from 0.14 mm ± 0.17 mm to 0.42 mm ± 0.15 mm with a maximum error of 0.59 mm were measured.

This very high accuracy is in the range of the thickness of the spinal dura mater.
ARCH-COMP22 Repeatability Evaluation Report
Authors: Johnson Taylor T
Published: December 2022

The repeatability evaluation for the 6th International Competition on Verifying Con- tinuous and Hybrid Systems (ARCH-COMP’22) is summarized in this report. The compe- tition took place as part of the workshop Applied Verification for Continuous and Hybrid Systems (ARCH) in 2022, affiliated with the 41st International Conference on Computer Safety, Reliability and Security (SAFECOMP’22). In its sixth edition, 25 tools had submit- ted artifacts through a Git repository for the repeatability evaluation, which were applied to solve benchmark instances through 7 competition categories. The majority of partic- ipants adhered to the specifications of this year’s repeatability evaluation, which was to submit scripts to automatically install and execute tools in containerized virtual environ- ments (specifically Dockerfiles to execute within Docker containers). Some categories used performance evaluation information from a common execution platform. The repeatability results represent a snapshot of current tools and the types of benchmarks on which they are well suited, and so that others may repeat their analyses. Due to the diversity of problems in verification of continuous and hybrid systems, as well as basing on standard practice in repeatability evaluations, we evaluate the tools with pass and/or failing of being repeatable.

There is controversy regarding the effect of different approaches on recovery after THR. Collecting detailed relevant data with satisfactory compliance is difficult.

Our retrospective observational multi-center study aimed to find out if the data collected via a remote coaching app can be used to monitor the speed of recovery after THR using the anterolateral (ALA), posterior (PA) and the direct anterior approach (DAA).

771 patients undergoing THR from 13 centers using the moveUP platform were identified. 239 had ALA, 345 DAA and 42 PA. There was no significant difference between the groups in the sex of patients or in preoperative HOOS Scores. There was however a significantly lower age in the DAA (64,1y) compared to ALA (66,9y), and a significantly lower Oxford Hip Score in the DAA (23,9) compared to PA (27,7). Step count measured by an activity tracker, pain killer and NSAID use was monitored via the app. We recorded when patients started driving following surgery, stopped using crutches, and their HOOS and Oxford hip scores at 6 weeks.

Overall compliance with data request was 80%. Patients achieved their preoperative activity level after 25.8, 17,7 and 23.3 days, started driving a car after 33.6, 30.3 and 31.7 days, stopped painkillers after 27.5, 20.2 and 22.5 days, NSAID after 30.3, 25.7, and 24.7 days for ALA, DAA and PA respectively. Painkillers were stopped and preoperative activity levels were achieved significantly earlier favoring DAA over ALA. Similarly, crutches were abandoned significantly earlier (39.9, 29.7 and 24.4 days for ALA, DAA and PA respectively) favoring DAA and PA over ALA. HOOS scores and Oxford Hip scores improved significantly in all 3 groups at 6 weeks, without any statistically significant difference between groups in either Oxford Hip or HOOS subscores.

No final conclusion can be drawn as to the superiority of either approach in this study but the remote coaching platform allowed the collection of detailed data which can be used to advise patients individually, manage expectations, improve outcomes and identify areas for further research.

We present the results of a friendly competition for formal verification of continuous and hybrid systems with nonlinear continuous dynamics. The friendly competition took place as part of the workshop Applied Verification for Continuous and Hybrid Systems (ARCH) in 2022. This year, 6 tools Ariadne, CORA, DynIbex, JuliaReach, Kaa and KeYmaera X (in alphabetic order) participated. These tools are applied to solve reachability analysis problems on six benchmark problems, two of them featuring hybrid dynamics. We do not rank the tools based on the results, but show the current status and discover the potential advantages of different tools.
