Published: September 2022

Timor Island, Indonesia has complex geological structures related to its tectonic history. There is an existing subsurface geological model that is based on geophysical data. It is limited to the regional crustal scale and has a relatively low spatial resolution. The objective of our study was to delineate the sedimentary basin configuration of the area, both laterally and vertically, based on gravity data. Spectral analysis of the Bouguer anomaly allowed for anomaly enhancement by wavenumber domain filtering. Two main basins were identified from elongated low gravity anomalies that follow a SW-NE trend, i.e., the Central Basin and the Atambua Basin. The 2½D gravity modeling of selected profiles perpendicular to the regional structural direction revealed the sedimentary fills of the basins and the basement based on their densities. The Bobonaro mélanges and Viqueque sequences dominate and overlay the syn-rift (Kekneno sequences) and post-rift (Kolbano sequences) with varying lithology. These para-autochthon sediments are dominated by shale and carbonaceous rocks. Their respective thicknesses and depths of burial imply the possibility of hydrocarbon generation. The underlying basement may be associated with the Australian crust protruding from the south.

Published: September 2022

This study aims to develop an assessment instrument to measure student collaboration and responsibility skills in the context of case-based physics learning that is valid, reliable, and practical. This type of research is called research development (R&D) using the 7 stages adapted from (Borg & Gall, 1989). Product validation was carried out to assess aspects of construction, substance, and language. The results of expert validation of the assessment instrument to measure collaboration and responsibility skills were 88.72% and 85.43%, with very valid criteria. Then, this assessment instrument was tested on 30 students and analyzed using the Rasch model. Based on the results of the test data analysis, we obtained that: (1) 14 items of the collaboration instrument and 9 items of the responsibility instrument were declared valid; (2) the reliability of the collaboration and responsibility skills assessment instrument was 0.82 and 0.71 with perfect and good criteria; and (3) the average value of the practicality test of the collaboration and responsibility skills assessment instrument was 90.72% and 91.80% with very high criteria.

Authors: Brito Eduardo Felipe de Sousa , Silva Leonardo Firmiano da , Araújo Jamille Carla Oliveira
Published: September 2022

O Seguro de vida envolve o risco da pessoa do próprio segurado, ou seja, a integridade física e a vida do próprio segurado, de modo que o interesse do segurado é que sua vida, saúde e integridade física estejam segurados contra imprevistos, como doenças, invalidez, acidentes e morte. De acordo com Leone Trindade Sene (2006) o seguro de vida é o contrato pelo qual o segurador se obriga, em contraprestação ao recebimento do prêmio a pagar ao segurado ou terceiros indicados no contrato importância, seja parte do capital ou do prêmio, quando ocorrer evento previsto no contrato do seguro de vida. Domingos, Afonso, Krieger Filho (2005) afirmam que o seguro de vida é um tipo de seguro que presta o serviço de garantir ao segurado e as pessoas indicadas no contrato recebam determinada quantia em dinheiro na ocorrência de algum evento previsto no contrato relacionado a vida. Portanto, o presente trabalho tem como objetivo verificar o percentual de indivíduos que possuem seguro de vida em duas universidades situadas na região nordeste do paraense na Universidade Federal do Pará (UFPA) -Campus Bragança e Universidade Federal e Rural da Amazônia (UFRA) -Campus Capanema. Para tanto, foi aplicado um questionário para aferir o percentual de pessoas que possuem seguro de vida, que o consideram importante e o perfil da população estudada, como idade, formação acadêmica e gênero. Após aplicação do questionário, foi registrado a participação de 61 (sessenta e um) indivíduos das instituições de ensino, dentre esses: docentes, discente e técnicos administrativos em educação. Analisada as respostas, a pesquisa revelou que a maioria dos entrevistados em duas universidades públicas federais na região nordeste paraense não possuem seguro de vida 70,5% eque apenas 29,5% dos entrevistados possuem seguro de vida. Porém, foi identificado que 73% consideram o seguro de vida importante, embora que não o possuam.Embora a maioria não tenha seguro de vida, o nível de pessoas que o possuem está acima da média brasileira, que é de 19%, e próximo à média mundial que é 32% de acordo com um estudo realizado na Universidade de Oxford. A pesquisa revela que apesar da maioria dos entrevistados não têm seguro de vida, a maioria absoluta o considera importante 77%, o que mostrando um grande paradoxo. Concluímos que os acadêmicos de duas instituições de ensino na região nordeste paraense possuem o percentual maior quando comparado a média brasileira. E, se aproxima da média mundial.

Published: September 2022

O que mais chama atenção e interesse por parte das pessoas para se trabalhar em uma determinada empresa é a qualidade de vida no trabalho. Tendo em vista essas informações, este artigo tem como objetivo apresentar o perfil de gestão de uma empresa produtora de Dendê em Tomé-Açu/PA. Trata-se de uma abordagem quali-quantitativa, de caráter descritivo e de campo, através da aplicação de um questionário, em escala Likert (1932) de cinco pontos, aplicada na área administrativa da empresa. Os resultados indicam que grande parte dos gestores é do sexo feminino, estão na faixa de 31 a 40 anos, possuem pós-graduação completa e estão parcialmente satisfeitos com a autonomia, a exposição de ideias, treinamento, entre outras. No entanto, um índice elevado de colaboradores declarou que suas atividades são estressantes e muitos se mantiveram neutros em questões como remuneração e valorização dos mesmos na visão da empresa. Se percebeu ainda, que a maioria dos colaboradores que apresentaram insatisfação com autonomia e privacidade foram do sexo feminino, um fato que precisa ser sanado, já que são maioria na gestão da empresa e também as que possuem maior formação.

Published: September 2022

One of the biggest challenges today is how to present data to users in a clear and easy way in different domains of application. One way to do this is to tell stories with data, as this makes it possible to improve user engagement and understanding of a given context. By using narrative elements, it is possible to provide readers with better explanations of what is being presented. To understand the research scenario about this topic, a systematic review of the literature was performed, through a snowballing procedure. As results, the main characteristics of these visualizations were identified as well as the genres and tools used in their development, and the main visualization techniques used. These results demonstrate that the most used genres are slideshows, data comics, annotated charts, magazine style, and flow chart. One of the main open questions is about the genres used for each - different - type of data, demonstrating that the topic is emerging and necessary.
Performance Analysis of Bulk Synchronous Parallel Algorithms
Authors: Martins Wellington Santos
Published: September 2022

In the last few years, there has been considerable interest in general purpose computational models of parallel computation to permit independent development of hardware and software. The BSP and related models represent an important step in this direction. This paper presents a methodology for the performance analysis of bulk synchronous parallel algorithms based on parameters which reflect the two-level memory hierarchy advocated by these models. A parallel sorting algorithm is taken as a case study where it is shown a close agreement between theoretical and experimental results.
The Performance of Cache Coherency in SCI-based Multiprocessors
Authors: Hexsel Roberto A. , Topham Nigel P.
Published: September 2022

The Scalable Coherent Interface (SCI) is an IEEE/ANSI standard that defines a hardware platform for scalable shared-memory multiprocessors. This paper contains a quantitative performance evaluation of SCI-connected multiprocessors that assesses both the communication and cache coherence subsystems. 1D, 2D and 3D tori with 16 and 64 nodes are investigated. For the architecture (100MHz Sparc, 2 levels of caches) and workload simulated, it was found that raw network bandwidth seen by a processing element is under 100Mbytes/s. The 3-D toros is 10-15% faster than the 2-D toros for programs that generate high leveis of network traffic. Otherwise, the differences in performance between 2-D and 3-D tori are negligible.

Published: September 2022

This paper presents the resource tuning in a multipath superscalar architecture model. The main goal of this model is to provide a high bandwidth for superscalar architectures that need a high instruction throughput. This architecture has an aggressive fetch mechanism to increase the number of instructions available to the execution stage of the pipeline, allowing a high number of instructions to be executed per cycle. To achieve this, instructions from multiple paths are fetched in the same clock cycle. The model results in a reduction of the occurrence of breaks in the flow. A more detailed study into the resource distribution throughout the architecture is needed. Simply increasing the number of resources to support throughput is not recommended, given the prohibitive implementation costs. The resource tuning of this superscalar architecture is then an important focus of research, to balance resource requirements and to tune them.

Published: September 2022

The difficulty of parallel applications to attain reasonable performance levels has motivated the development of performance debugging tools such as Paradyn, StormWatch, and Carnival. Although, developers have usually demonstrated tool capabilities on different kind of applications, often no evaluation of tool effectiveness has been reported from less especialized users facing the task of developing efficient parallel applications with the only support of performance debugging tools. This paper begins to fill this gap. More specifically, we evaluate the effectiveness of Carnival to support the development of software DSM applications by programmers having little background on parallel programming and performance debugging tools. Using Carnival we port four parallel applications to TreadMarks, a well-known software DSM system. Two applications (Raytrace and LU) are from the SPLASH-2 suite and other two applications (TSP and IS) belong to the TreadMarks application benchmarks. Our results show that the causes of synchronization and communication problems in the applications were precisely diagnosed by Carnival. In addition, Carnival diagnostics enabled simple code modifications that increased application performance by up to a factor of 2 in TreadMarks applications and as much as 46 times in Splash2 applications. The main difficulty we faced was Carnival large trace files specially in Raytrace which could be solved by augmenting the granularily of the application instrumentation. In overall, Carnival offers a simple and friendly interface for performance vizualization. Our conclusion is that Carnival offers an effective tool to implement efficient software DSM applications.

Evaluation of Immune Response in Asymptomatic Children with Parents withCOVID-19
Authors: ONUR Hakan , RAHMANALI ONUR Arzu
Published: September 2022

Objective: From a public health perspective, understanding the pathogenesis and transmission of SARS-CoV-2 in children is important both in understanding the role of the pediatric population in the transmission and spread dynamics of the epidemic, and in controlling the severity of the pandemic. The present study investigated the role of children in the spread of COVID-19 infection.

Methods: Children, who applied to the Pediatrics Outpatient Clinic for routine check-ups between May and June 2021, with no symptoms and were not tested with RT-PCR for COVID-19 although their parents and close relatives were diagnosed with COVID-19 in the last 6 months, were evaluated prospectively.

Results: Thirty-five cases, 20 of whom were male, were included in the study. While 17 of the children had contact with only 1 case, 18 of them had contact with 2 or more cases. While the mean antibody values for IgG of the subjects with one contact were 1.55±1.93 S/C and IgG-spike was 910.6±1512.02 AU/mL, the mean antibody values for IgG of the subjects with 2 or more contacts were 2.21±2.07 S/C and 1289.15±1750.49 AU/mL for IgG-spike. Twelve of the cases came into contact with patients in autumn, 21 in winter, and 2 in spring.

Conclusion: As the virus spreads in the community, the dynamics and clinical features of the disease will change. There should be data with more cases in a wider geographical distribution. However, studies show that children are not the primary source of households to date. It was observed that the severity of the disease and more than one contact did not affect the severity of the disease in terms of antibody level.

The One-Over-Many Argument and Common Things
Authors: Crivelli Paolo ,   Philosophy Documentation Center
Published: September 2022

In On Ideas, Aristotle presents and criticizes an argument for ideas referred to as “the One-over-Many.” On the basis of an uncontroversial fact concerning a group (for instance, the fact that each of the many men is a man), the One-over-Many infers that there is something predicated of each of the members of the group (for instance, that there is something predicated of each of the many men). It then tries to show that the thing predicated in common is an idea. Aristotle criticises this argument by claiming that if it were sound it would show that there are ideas of negations, a result which the Platonists should reject. Since Aristotle himself refuses the existence of “common things,” i.e., Aristotelian universals, of negations, he is committed to the view that the One-over-Many fails to prove the existence not only of ideas, but also of “common things.”
The Development of a Planning Boat Model and Environmental Measurements for Free Running Model Tests
Authors: Wang Xinguo , Sallam Omar , Moulton David , Fürth Mirjam
Published: September 2022

For decades, the performance and efficiency of High Speed Craft (HSC) have been tested and evaluated in towing tanks; these tests are performed under ideal conditions. During towed testing the scaled model is often only free to move in heave and pitch and the effect of surge cannot be evaluated. Self propelled tests are rare meaning the drag, noise and turbulence of the thruster propellers are not considered. This paper presents a detailed step by step workflow of designing and manufacturing a self-propelled (HSC) to be tested in a calm water free running test in the Offshore Technology Research Center (OTRC) wave basin in Texas A&M University. The paper shows the hull parametric design, thruster and propeller selection and the data acquisition system design. The study includes a quantitative and qualitative comparison for the effect of the propeller hull interaction, results are compared with exciting towing tank data for the same hull geometry. An experimental straight forward motion step response is implemented to identify the vehicle speed transfer function for closed loop forward speed controller design. The paper also presents the use of computer vision applications in the experiment measurements such as the Visual-SLAM algorithm for the accurate 6-DOF HSC motion tracking and the use of the stereo-vision for studying the wave pattern downstream of the hull quantitatively and qualitatively.
Quantifying Interfaces in General Arrangement Drawings
Authors: Gaspar Henrique , Andrews David
Published: September 2022

An algorithm for quantifying interfaces in general arrangement 2D drawings is the core of this work. The method here presented builds upon an unpublished prototype developed in 2015, representing each relevant GA space as a two-dimensional design block, heavily inspired by the design building block (DBB) philosophy. An algorithm checks the interfaces of all design blocks in real-time and presents a matrix with the quantification. Both algorithm and interactive web-application are available online for use and scrutiny. The idea is relatively simple, almost ludic, but to the knowledge of the authors no similar method has been public available yet. Fancy data-driven graphics are used to grasp interpretations of these values. A proposal for diverse use of interaction data in GA is mentioned in the discussion, as well as an invitation for colleagues to reproduce and improve the method.
The Hydrodynamics of Elogrid
Authors: Tanttari Juha , Hämäläinen Raimo , Rautaheimo Patrik
Published: September 2022

The ship hull hydrodynamics impact to global energy consumption is about quarter of all energy used in the world. The amount of fuel consumed in an average Panamax container is over 200t per day.

The ship hydrodynamics is improved by careful design of the body, but also all the appendages needed in the ship are aligned with streamlines to avoid excess resistance. The bow thruster tunnels and propeller units providing transversal thrust forces for maneuvering purposes are typically adding ship total resistance 2-3% per tunnel. The additional resistance from the tunnels is commonly decreased by vertical grid bars mounted in the opening – those reduce the resistance to 1-2% per tunnel. However those grids typically decrease the maneuverability increasing the propeller thrust resistance 7-12% depending on grid density and design. Vertical grids density having best performances reducing tunnel additional resistance contribute highest thrust losses.

Elogrids (pat.pend) A new design for the tunnel opening grids has been developed to maintain the impact decreasing additional resistance at same level with commonly used dense vertical grids, but instead of reducing the thrust - keep or improve the thrust forces from the tunnel thrusters when needed in maneuvering. Basic idea of the stator type Elogrids is with the bars and circles prevent water flow into the tunnels while ship steaming and improve the propeller performances with same components to concentrate propeller jet produced at propeller pressure side and improve the flow pattern into the propeller at suction side.

Testing The Elogrid performances has been simulated by computational fluid dynamics, designed based on the dimensions optimized and manufactured. Now these first pilots of the Elogrids has been installed to a passenger ferry with two Dp=2.4m tunnels and also tested in full scale.

The testing of Elogrids include bollard pull tests to find these impact on thrust forces, vibrations and noise – and comparison of ship fuel economy before and after installation of Elogrids. The fuel economy comparison need as similar circumstances as possible to detect the impact reliably. Main challenge is slightly different conditions each time the ferry operates. A huge amount of ship data is needed to get statistically reliable results.

Conclusions The full scale testing of Elogrids show 1.5% reduction of additional resistance, simulated results are between 2 – 2.5%. Compensating the draught differences lead test results closer to simulated values. Bollard pull testing show in average 5% improvement to thrust when Elogrids were installed, simulated values were between 1.6-3.6%.

The simulated values were proposing bit higher saving potential, possibly explained with draught differences in test and simulation data, and for pull test they were noticed to be slightly conservative when compared to test results. The vibration levels dropped 12% in average after grids were installed.
Learning Design From Day One of Undergraduate Studies
Authors: Birmingham Richard
Published: September 2022

All engineering courses, including naval architecture, have to ensure that the students gain a firm grasp of both analysis and synthesis techniques. However there is a significant difference between how these two are dealt with in educational programmes: analysis techniques are conventionally taught in detail and extensively throughout the three or four years of an undergraduate course, while synthesis is often ignored until the final stages of a degree programme, and then dealt with in a relatively cursory fashion. This is understandable as analysis techniques are far more involved, and require many hours of study to grasp and, more fundamentally, it can be asked, how can you synthesise a solution without first learning to analyse and evaluate it? However naval architects are essentially designers, so it would clearly be beneficial if our students were learning the entire process of design, meaning both analysis and synthesis, from the earliest stages of their programmes.

This paper will report on the recent experience at Newcastle University where, following a review and reorganisation of our undergraduate programmes, design theory and practice has been introduced to the course from day one. In the paper the rational for the reorganisation will be briefly outlined, but the main focus of the paper will be on the teaching and learning process, which has involved presenting the students with a series of paper and cardboard boat design challenges that they have to respond to by undertaking design-and-build exercises throughout the first semester of their course. Despite the students having little of no knowledge of analysis techniques the challenges introduce them to the concepts of elicitation, creativity, synthesis, optimisation, satisfycing, evaluating, and of virtual prototyping.

As the marine industry looks to develop and integrate autonomous vessels and platforms into the global fleet, new design challenges emerge as the complexity of the vessel design process increases in parallel with the growing need for larger and more diversified multi-disciplinary design teams. The design of autonomous vessels presents the need for novel marine designs with the use of diverse skill sets, knowledge sets, and technical backgrounds from the early stages of the design process. In developing novel marine designs, explicit, implicit, and tacit knowledge is needed for the development of successful concepts. Given the novelty and complexity of autonomous vessels, a significant amount of conditional, path dependent tacit knowledge is required in the design process. To form successful designs and to form a foundation for future development of autonomous vessels, it is critical that methods and frameworks be developed to represent, share, and codify necessary tacit knowledge and its interdependencies within system design in explicit form ahead of full product development.

To be able to account for the multidimensional relationships that should, could or will exist between design parameters and associated design decisions, a bridge between implicit and tacit knowledge is needed. One approach to bridging the gap between tacit and implicit knowledge is through the shared conceptualization of an ontology. Due to the fact that ontologies can separate concepts and define context-dependent relationships, ontologies have the possibility to enable the understanding of potential design implications associated with integration of the multiple contextual views of design artifacts within a singular framework. This paper will provide a survey of the current uses of ontologies and their possible applications ranging from concept to detailed design across naval design generally and autonomous vessels specifically.

Although, occupational injuries and fatalities onboard merchant ships show decreasing trends over the years, they are still significantly above the rates observed in the land based industries.

This study critically evaluates the maritime occupational injuries and fatalities in international merchant shipping over the last 20 years by reviewing the reported studies and publications; available major data sources and taxonomies around the world with an aim of identifying the causes of those injuries and fatalities. The study, also present the detailed results of the systematic analysis of occupational accident database highlighting main causal factors.

The analyses are carried out by studying the injuries and fatalities separately, in order to have a deeper understanding and better identification of the circumstances leading to injuries and fatalities. The study also presents the design and operational deficiencies leading to occupational accidents onboard merchant ships.

Results of the data analyses clearly indicate that fall overboard of a person is the top immediate causal factor for fatalities, while slips, trips and falls on the same level is the top immediate causal factor for injuries.
To blind or not to blind
Authors: Baeza Noci Jose
Published: September 2022

During this COVID-19 pandemic, I was invited to review several papers from well-reputed and high-impact factor journals. Surprisingly, the review of these papers was not blind, allowing me to know the authors and their institutions.

Not blinding the reviews allows reviewers to decide whether accept or not the task and can predispose the reviewer's final decision. What was more striking for me was to know that some authors do not accept blind reviews.

In our journal, all papers are blindly reviewed by two well-reputed reviewers with expertise in the topic. BLINDLY. Even our copyeditor, who checks and corrects English language mistakes, is blind to the paper's authorship.

Although the time for publishing is sometimes long, the edition process is systematic and thoughtful, even changing or adding some reviewers when necessary. All the process but creating the PDF files is voluntary and free, done by different WFOT members.

In issue 6, we have collected different topic papers; the paper from Recio deserves special mention, as it has belonged to grey literature since 2007. I read this paper in 2008, but I have not been able to contact ANY of the authors till recently Dr. Javier Cespedes found Dr. Marizta Palma that authorized its publication in our journal.

Issue 7 will be the Proceedings of the 7th Meeting of the WFOT that will take place in Bucharest in 2022.

We are now collecting papers for issue 8.
2014 Doboj Floods – Consequences and Hazard Elimination Activities
Authors: Amidžić Goran
Published: September 2022

The Republic of Srpska is susceptible to natural disasters, with particular regard to floods. Floods had caused human losses and property damage to both civilian and commercial facilities, road infrastructure and other infrastructure, on several occasions, including the 2014 floods. It is not always possible to predict natural disasters but human and material losses may be reduced if institutions undertake planned prevention activities and educate the population in terms of flood protection and risk reduction. The paper addresses floods as the natural disaster to which the Republic of Srpska is susceptible due to a long network of non-regulated water streams and frequent heavy rains. A special attention is paid to the floods which heavily affected the city of Doboj in 2014 as we analyze the activities on hazard elimination and consequence mitigation. The analysis is based on the study, assessment and plans designed in order to protect the city from floods in near future. Along with that we analyzed the impact of floods on the changes in the size of traffic flow requirements on the part of the M-17 road damaged in floods.

Acute myeloid leukaemia (AML) cells interact and modulate components of their surrounding microenvironment into their own benefit. Stromal cells have been shown to support AML survival and progression through various mechanisms. Nonetheless, whether AML cells could establish beneficial metabolic interactions with stromal cells is underexplored. By using a combination of human AML cell lines and AML patient samples together with mouse stromal cells and a MLL-AF9 mouse model, here we identify a novel metabolic crosstalk between AML and stromal cells where AML cells prompt stromal cells to secrete acetate for their own consumption to feed the tricarboxylic acid cycle (TCA) and lipid biosynthesis. By performing transcriptome analysis and tracer-based metabolic NMR analysis, we observe that stromal cells present a higher rate of glycolysis when co-cultured with AML cells. We also find that acetate in stromal cells is derived from pyruvate via chemical conversion under the influence of reactive oxygen species (ROS) following ROS transfer from AML to stromal cells via gap junctions. Overall, we present a unique metabolic communication between AML and stromal cells and propose two different molecular targets, ACSS2 and gap junctions, that could potentially be exploited for adjuvant therapy.

Although vaccination is broadly used in North American swine breeding herds, managing swine influenza is challenging primarily due to the continuous evolution of influenza A virus (IAV) and the ability of the virus to transmit among vaccinated pigs. Studies that have simultaneously assessed the impact of vaccination on the emergence of IAV reassortment and genetic variation in pigs are limited. Here, we directly sequenced 28 bronchoalveolar lavage fluid (BALF) samples collected from vaccinated and unvaccinated pigs co-infected with H1N1 and H3N2 IAV strains, and characterized 202 individual viral plaques recovered from 13 BALF samples. We identified 54 reassortant viruses that were grouped in 17 single and 16 mixed genotypes. Notably, we found that prime-boost vaccinated pigs had less reassortant viruses than nonvaccinated pigs, likely due to a reduction in the number of days pigs were co-infected with both challenge viruses. However, direct sequencing from BALF samples revealed limited impact of vaccination on viral variant frequency, evolutionary rates, and nucleotide diversity in any IAV coding regions. Overall, our results highlight the value of IAV vaccination not only at limiting virus replication in pigs but also at protecting public health by restricting the generation of novel reassortants with zoonotic and/or pandemic potential.

Background:

Variants of concern (VOCs) of SARS-CoV-2 have caused resurging waves of infections worldwide. In the Netherlands, the Alpha, Beta, Gamma, and Delta VOCs circulated widely between September 2020 and August 2021. We sought to elucidate how various control measures, including targeted flight restrictions, had impacted the introduction and spread of these VOCs in the Netherlands.

Methods:

We performed phylogenetic analyses on 39,844 SARS-CoV-2 genomes collected under the Dutch national surveillance program.

Results:

We found that all four VOCs were introduced before targeted flight restrictions were imposed on countries where the VOCs first emerged. Importantly, foreign introductions, predominantly from other European countries, continued during these restrictions. After their respective introductions into the Netherlands, the Alpha and Delta VOCs largely circulated within more populous regions of the country with international connections before asymmetric bidirectional transmissions occurred with the rest of the country and the VOC became the dominant circulating lineage.

Conclusions:

Our findings show that flight restrictions had limited effectiveness in deterring VOC introductions due to the strength of regional land travel importation risks. As countries consider scaling down SARS-CoV-2 surveillance efforts in the post-crisis phase of the pandemic, our results highlight that robust surveillance in regions of early spread is important for providing timely information for variant detection and outbreak control.
