Abstract
Powerful relativistic jets in active galactic nuclei (AGN) are believed to be originated from the accretion of material onto the supermassive black hole (SMBH)1. The nearby radio galaxy M87 is one of the best examples of this phenomenon, and the recent detection of a black-hole shadow with the Event Horizon Telescope provided compelling evidence for this paradigm2. However, whether the central SMBH in M87 has a spin or not, a fundamental parameter of a BH along with the mass, remains unconstrained by observations since the appearance of the photon ring is rather insensitive to the spin2-4. A clue to this challenge is to trace the long-term evolution of the innermost jet base where the central BH and accretion disk tightly regulate its flow dynamics. Here we report an extensive analysis of the morphological evolution of the M87 jet nozzle based on 170 high-resolution radio images spanning more than two decades. The ensemble of the data reveals a periodic (a period of 11 years) variation of the jet direction with a peak-to-peak amplitude of ~10 deg on the sky. A successful fit of a precession model to the data as well as general-relativistic magnetohydrodynamic simulations strongly supports the presence of a spinning BH in M87, inducing a Lense-Thirring precession of a misaligned accretion disk by the frame-dragging effect5. Our results suggest that jet precession with a spinning BH can commonly exist in other more distant AGN but had evaded detection due to the small magnitude and long period of position angle variation.

Published: March 2023

Abstract
Background
Junctional epidermolysis bullosa is a rare skin and mucosal disorder characterized by blister formation in response to minor trauma and extracutaneous manifestations. There have been no reports of cardiac surgery and prognostication in patients with epidermolysis bullosa due to skin and mucosal fragility.
Case presentation:
A 55-year-old man presented with congenital junctional epidermolysis bullosa, hypertension, and vasospastic angina. He complained of dyspnea on exertion, and transthoracic echocardiography revealed severe aortic valve regurgitation, moderate aortic valve stenosis (tricuspid valve), and severe mitral valve regurgitation. Considering that the skin condition in the right chest wall was relatively healthy, the right thoracotomy approach was preferred and totally endoscopic concomitant mitral valve repair and aortic valve replacement were performed using a sutureless bioprosthetic valve (Perceval™ (Corcym, Group, Milan, Italy)). Polyurethane and silicon dressing foams were used to protect the skin at the site of contact with the bag valve mask, arterial pressure catheter, intravenous catheter, and the tracheal intubation tube. Vertical mattress sutures were used for the skin sutures. The postoperative course was uneventful, and the patient was discharged nine days after the operation. There was no indication for reoperation until three years follow-up period.
Conclusions
The totally endoscopic concomitant aortic and mitral valve surgery using Perceval™ prosthesis can be performed safely in patients with junctional epidermolysis bullosa by adequate protection of the skin and mucosa.

Abstract
Objectives: This study aims to assess the effectiveness of a multidomain intervention program on the change in functional status of hospitalized older adults.
Design: This single-arm, prospective, non-randomized interventional study investigates the efficacy of a multidomain interventional program including cognitive stimulation activity, simple exercises, frailty education, and nutrition counseling.
Setting and participants: At a tertiary hospital in southern Taiwan, 352 eligible patients were sequentially enrolled. Included patients were aged ≥65 years (mean age, 79.6 ± 9.0 years; 62% male), scored 3–7 on the Clinical Frailty Scale (CFS), and were hospitalized in the geriatric acute ward.
Intervention: Those receiving standard care (physical rehabilitation and nutrition counseling) during January–July 2019 composed the historical control group. Those receiving the multidomain intervention during August–December 2019 composed the intervention group.
Measurements: The primary outcome was the change in activities of daily life (ADL), as assessed using the Katz Index and a generalized estimating equation model. The length of hospital stay, medical costs, and re-admission rates were secondary outcomes.
Results: Participants undergoing intervention (n = 102; 27.9%) showed greater improvements in the ADL and CFS during hospitalization (ADL adjusted estimate, 0.61; 95% CI, 0.11–1.11; p = 0.02; CFS adjusted estimate, −1.11; 95% CI, −1.42– −0.80; p < 0.01), shorter length of hospital stay (adjusted estimate, −5.00; 95% CI, −7.99– −2.47; p < 0.01), lower medical costs (adjusted estimate, 0.58; 95% CI, 0.49–0.69; p < 0.01), and lower 30- and 90-day readmission rates (30-day adjusted OR [aOR], 0.12; 95% CI, 0.27–0.50; p < 0.01; 60-day aOR, 0.04; 95% CI, 0.01–0.33; p < 0.01) than did controls.
Conclusions: Participation in the multidomain intervention program during hospitalization improved the functional status and decreased the hospital stay length, medical costs, and readmission rates of frail older people.

Abstract
This study assessed changes in the sociodemographic structure, land use, diet and nutritional status of the population of a rural village in West Java, Indonesia between 2000–2001 and 2015–2017. This was a period of rapid socioeconomic change in the country. Over this period, the village’s population increased by 50%. The growing population was largely engaged in non-agricultural employment within the village or in nearby cities, and the village maintained its function as a farming village without major changes in the local land use or ecosystem. In 2000, the diet, nutritional intake and health status of the villagers were fairly uniform. Indicators based on BMI, for example, classified 98% of target children and 70% of target mothers as ‘normal’, regardless of household economic status. However, by 2015, more people worked outside the village and dependence on a market economy had increased. Dependence on food from outside the village, such as processed foods that are cheap and easy to obtain and store, had also increased. Foods such as cassava, taro, and sweet potatoes, which were grown and consumed in 2000, were not consumed in 2015. The amount of beans, nuts, and vegetables consumed had also decreased. Additionally, the use and sharing of natural resources and the accompanying knowledge transfer had been gradually lost. As a result, variation in diet, nutritional intake, and health conditions within the village significantly increased over time, and overnutrition and undernutrition coexisted by 2015.
Comparison of Central Venous Catheter Thoracic Drainage with Traditional Closed Thoracic Drainage after Minimally Invasive Surgery for Esophageal Cancer: A Retrospective Study
Authors: Zhao Yang , Ma Yue , Bai xia , Wang Tao , Song Dong , Li Tao 
Published: March 2023

Abstract
Background
To compare the effectiveness and safety of central venous catheter thoracic drainage (CVC-TD) with traditional closed thoracic drainage (TCTD) after minimally invasive surgery for esophageal cancer.
Methods
We conducted a retrospective study of 103 patients who underwent minimally invasive surgery for esophageal cancer at our institution between January 2017 and December 2019. Forty-four patients received CVC-TD, while 59 patients received TCTD. We compared the following outcomes between the two groups: drainage volume, drainage duration, incidence of postoperative complications (including pleural effusion, pneumonia, and atelectasis), length of hospital stays, and overall survival.
Results
The drainage volume and duration were similar between the two groups. However, the incidence of postoperative complications was significantly lower in the CVC-TD group than in the TCTD group (p < 0.05). The length of hospital stay was also shorter in the CVC-TD group (p < 0.05). There was no significant difference in overall survival between the two groups.
Conclusion
CVC-TD is a safe and effective alternative to TCTD after minimally invasive surgery for esophageal cancer. It may help reduce the incidence of postoperative complications and shorten the length of hospital stay. Further studies are needed to confirm these findings.
Subfossil chironomid assemblages as indicators of remedial efficacy in the historically contaminated St. Lawrence River at Cornwall, Ontario
Authors: Armstrong Isaac , Moir Katherine , Ridal Jeffrey , Cumming Brian 
Published: March 2023

Abstract
Long-term data are required to quantify the impacts of historic industrial pollution and subsequent remedial action on the nearshore benthic community in the St. Lawrence River Area of Concern at Cornwall, Ontario. Specifically, high-quality temporal records are needed to understand changes in benthic invertebrate assemblages in response to multiple possible drivers including industrial pollution, environmental heterogeneity, and climate warming. We compare long-term records of subfossil chironomid assemblages and geochemical variables among sediment cores from two Cornwall sites with differing pollution histories and a minimally disturbed downstream reference site. Chironomids were functionally absent from the Cornwall sediment cores when mercury and zinc concentrations were elevated. As metal concentrations decreased in more recent sediment intervals, chironomid abundance and the relative abundance of pollution-sensitive taxa increased. Recently deposited sediment in all three sediment cores display increased relative abundance of warm-water, macrophyte-associated taxa. We conclude that these temporal changes in chironomid assemblages provide evidence for ecological recovery for both of the impacted sites, consistent with the objectives of the current management strategy. These findings advance our understanding of industrial impacts on fluvial chironomid ecology, directly inform local management strategies, and further develop the application of chironomids as bioindicators for contaminated sediments.
Ground Joinability and Connectedness in the Superposition Calculus
Authors: Duarte André , Korovin Konstantin 
Published: March 2023

Abstract
Problems in many theories axiomatised by unit equalities (UEQ), such as groups, loops, lattices, and other algebraic structures, are notoriously difficult for automated theorem provers to solve. Consequently, there has been considerable effort over decades in developing techniques to handle these theories, notably in the context of Knuth-Bendix completion and derivatives. The superposition calculus is a generalisation of completion to full first-order logic; however it does not carry over all the refinements that were developed for it, and is therefore not a strict generalisation. This means that (i) as of today, even state of the art provers for first-order logic based on the superposition calculus, while more general, are outperformed in UEQ by provers based on completion, and (ii) the sophisticated techniques developed for completion are not available in any problem which is not in UEQ. %In particular, this includes key simplifications such as ground joinability, which have been known for more than 30 years. In fact, all previous completeness proofs for ground joinability rely on proof orderings and proof reductions, which are not easily extensible to general clauses together with redundancy elimination. In this paper we address this limitation and extend superposition with ground joinability, and show that under an adapted notion of redundancy, simplifications based on ground joinability preserve completeness. Another recently explored simplification in completion is connectedness. We extend this notion to ``ground connectedness'' and show superposition is complete with both connectedness and ground connectedness. %We implemented ground joinability and connectedness in a theorem prover, iProver, the former using a novel algorithm which we also present in this paper, and evaluated over the TPTP library with encouraging results.
An integrated AHP-PROMETHEE II ranking method to evaluate the resilience of sewer networks considering urban flood and ground collapse risks
Authors: Zhang Chuanli , Kwon Soonwon , Oh Jeill , Park Kyoohong 
Published: March 2023

Abstract
The aim of this study is to present criteria to evaluate the resilience of sewer networks related to ground collapse and urban flooding likely to occur in a specific region and then to determine the ranks of the sewer networks resilience of the selected regions to show the applicability of the analytic hierarchy process (AHP) and the Preference Ranking Organization Method for Enriching Evaluations (PROMETHEE II) method. Fourteen evaluation criteria representing resistance, reliability, redundancy, and response and recovery are presented and their weights are estimated by the AHP by asking questionnaires to 10 sewer experts, leading to the result that the sub-criteria of reliability showed the highest importance, followed by the length ratio of good pipelines (under resistance) and adequacy of the flow capacity of the bypass pipelines (under redundancy). Four separate small blocks of drainage areas (total area of 3.57 km2; sewer length of 50.6 km) in Seoul are chosen for the case study. Using appropriate preference functions and thresholds for each evaluation criterion for PROMETHEE II application yields the resilience rankings of four blocks as Block III &gt; Block IV &gt; Block I &gt; Block II. A sensitivity analysis was also carried out by changing the weights.

Published: March 2023

В статье рассмотрена динамика формирования карьерных ориентаций у студентов психологического направления. Актуальность исследования объясняется важностью понимания особенностей профессиональной направленности будущих профессионалов. Понимание и сознание собственных якорей карьеры важно для любой личности, желающей построить успешную и комфортную карьеру. Обобщенное рассмотрение системы ценностей в профессиональном плане позволяет составить общий портрет будущего специалиста, что позволит работодателям создавать оптимальные условия для успешного найма сотрудников. Новизна работы заключается в проведении лонгитюдного исследования якорей карьеры на одной и той же группе на протяжение 3 лет, что позволяет делать более объективные выводы о изменения карьерных предпочтений, нежели чем при проведении исследования на разных группах. Во Введении автором обозревается актуальность исследования, а также основные теоретические подходы, обозревающие такой феномен как «Якоря карьеры». Для исследования проводилось анкетирование группы студентов психологического направления из 20 человек на первом, втором и третьем курсе обучения. В разделе «Методы» представлены основные способы анализа теоретических и эмпирических данных. Результаты исследования показывают наличие значимых различий между данными, полученными на первом и втором курсе, обнаружены изменения в определение приоритетных якорей карьеры среди группы на каждом году обучения. В разделе «Обсуждение результатов» автор отмечает, что несформированность и малая дифференцированность карьерных ориентаций в целом характерна для студентов психологов, в особенности на первом курсе из-за отсутствия необходимого опыта и знаний, наличия мифов и обыденных установок относительно будущей профессиональной деятельности. Также отмечено, что в процессе обучения так или иначе будет формироваться разочарование относительно некоторых особенностей будущей карьеры, в связи с чем также меняются профессиональные предпочтения.

Во введении автор раскрывает актуальность исследования современных медиа как образовательного ресурса. Современные социальные сети, в особенности «TikTok» зачастую воспринимаются как исключительно развлекательные. Однако, в последние годы возникла тенденция публикации в «TikTok» различного обучающего контента, который может способствовать вовлечению молодых людей в интересующие их области. В разделе «Методы» приводятся используемые автором инструменты и методики сбора данных. Были применены: анкетирование участников исследования с помощью авторской методики и тестирование студентов с помощью методики А.А. Реана «Методика диагностики позитивной (надежда на успех) и негативной (боязнь неудачи) мотивации». Также автором был использован метод математической обработки данных результатов экспериментального исследования. В качестве эмпирического объекта исследования выступали студенты-психологи (60 человек), преимущественно возраста 19 лет. В разделе «Результаты» говорится о том, что из всех опрошенных на вопрос об использовании социальной сети TikTok вариант «Да, использую» выбрало большинство человек, что составило 70,7 % от общего числа респондентов. Основной вопрос, считают ли участники опроса данный вид контента полезным в повышении мотивации к изучению психологии показал, что большая часть респондентов согласны или скорее согласны, чем не согласны (92,7 %). В обсуждении результатов приводятся исследования других авторов, изучающих данную проблему. В заключении приводятся итоги проведённого исследования. Таким образом, путем авторского опроса было выявлено, что социальная сеть TikTok оказывает положительное влияние на вовлеченность в изучении психологии. 59,5 % опрошенных. Результаты показали, что 88,1 % считают данный вид контента способным повысить заинтересованность (вовлеченность) в изучении психологии.
Structure-Function Relationship of Homogentisate 1,2-dioxygenase:
Understanding the Genotype-Phenotype Correlations in the Rare Genetic
Disease Alkaptonuria
Authors: Bernini Andrea , Spiga Ottavia , Santucci Annalisa 
Published: March 2023

Abstract:
Alkaptonuria (AKU), a rare genetic disorder, is characterized by the accumulation of homogentisic
acid (HGA) in organs, which occurs because the homogentisate 1,2-dioxygenase (HGD) enzyme
is not functional due to gene variants. Over time, HGA oxidation and accumulation cause the
formation of the ochronotic pigment, a deposit that provokes tissue degeneration and organ malfunction.
Here, we report a comprehensive review of the variants so far reported, the structural studies on
the molecular consequences of protein stability and interaction, and molecular simulations for pharmacological
chaperones as protein rescuers. Moreover, evidence accumulated so far in alkaptonuria research
will be re-proposed as the bases for a precision medicine approach in a rare disease.
EdTech and the Saudi EFL learners: Bane or boon?
Authors: Aljafen Bandar Saleh 
Published: March 2023

Educational technology in the English as a Foreign Language (EFL) classroom has great potential to usher in innovativeness and authenticity in the language instruction and learning processes apart from facilitating collaboration, cooperation, and engagement. Consequently instruction can take newer pathways that ensure these qualities along with enhancing learners’ language skills. Data on the application of edtech tools were gathered from 60 undergraduate EFL learners and four teachers at Qassim University, Saudi Arabia. The free version of Grammarly was found to be the one most accessed by the participants for grammar and language enrichment in academic writing assignments, followed by Writer, Scribens, and Ginger, in that order. Teachers, on the other hand, were apprehensive of learners’ dependence on apps and perceived these as hurdles in their learning as they got corrected and improved versions of their writing but without detailed explanations which encouraged a tendency in the learners to rely on these free apps.
