Facebook Mobile For Wave 3


Over the years Facebook has expanded to include multimedia content and sharing content initially posted by others on Facebook or elsewhere. All stuff that seems rudimentary to us now, but at the time were pioneering innovations from Facebook and other members of that first post-MySpace wave of social networks.




Facebook Mobile For Wave 3



Choose a background for your new videos such as your podcast or music cover art - You can also use a solid colour and add some text. To increase motion, and make your videos feel more dynamic you can add a waveform animation synced to your audio.


6. Tap on the lyrics to change what part of the song you want to feature. Using the sound wave-bar at the bottom, select a segment of the song. By default, it'll start in the middle of the chorus. You can also adjust the length of the snippet.


Mobility data from Facebook users were available from 22 March, and from mobile phone operators from 27 April. An analysis of the mobility patterns among approximately 6,600 Facebook users (Fig. 3a) shows that around 14.2% of users left Dhaka between 23 and 26 March, indicating a mass migration out of Dhaka to all areas of the country. The displacement of individuals from the city to other parts of the country is illustrated by the increase in the population relative to the baseline in rural areas such as Barisal. Note the large spike of movement associated with the evacuation of Barisal due to Cyclone Amphan in May13. Interestingly, from Fig. 3a, in areas such as Gazipur and Narayanganj, it is apparent that, after initial displacement, people returned in late April14; our data show that this was followed by a return to Dhaka in late May (Fig. 3a).


Given the daily migration of the Bangladeshi population into and out of major cities, the risk for sustained transmission and expansion of SARS-CoV-2 remains extremely high and limits the effectiveness of behavioural interventions. This highly mobile population seems to have rapidly transported lineages across the country. This occurred mainly when workers living and working in cities returned home to rural areas because schools, offices and other working places closed.


To investigate the emergence of lineages of concern Alpha (B.1.1.7) and Beta (B.1.351) in Bangladesh, a Nextstrain phylogenetic tree was built (Fig. 4). This revealed continuous transmission of lineage B.1.1.25 from the first wave and showed that B.1.1 and B.1.36 had been eliminated. Multiple introductions of Alpha B.1.1.7 occurred in Bangladesh after December 2020, but most were not established. More recently, in February 2021, a transmission chain became established in the community that resulted in non-travel-associated cases. Most concerning is the recent dominance of Beta (B.1.351), which has been assigned to a large number of cases that were not associated with travel and is responsible for 47% of our randomly sampled and recently sequenced cases. More than 85% of our Beta (B.1.351) sequences were sampled in Dhaka. Several other researchers who are sequencing viruses sampled in Bangladesh have deposited Beta (B.1.351) lineage sequences in GISAID (384 as of July 2021), indicating a lineage expansion and confirming that the dominance in our random sample is not a result of sampling bias. Further surveillance is necessary to investigate how this imported lineage has established and dominated the epidemic in Bangladesh so rapidly and what effect this lineage is having on transmissibility, mortality and immunity there.


In 2020, we sequenced 67 viral genomes from six administrative areas (divisions) of Bangladesh using a nanopore MinION device and combined these sequencing data with already-deposited global SARS-CoV-2 genomes (including 324 from Bangladesh COVID-19 cases) to show how early repeated international introductions into Bangladesh were replaced by endemic spread of three dominant lineages that dispersed the country in late March. Population mobility patterns analysed from digital trace and mobile phone data showed that the switch in the dynamics of SARS-CoV-2 genomic epidemiology coincided with migration out of cities to the rest of the country. In 2021, we again used nanopore sequencing to provide complete genome sequences of an additional 85 samples that were isolated between November 2020 and April 2021. The 2021 results revealed the presence of VOC Beta (B.1.351) in Bangladesh and its dominance in Dhaka, the capital of Bangladesh.


Our analyses of the genomic epidemiology of SARS-CoV-2 and population mobility in Bangladesh during the first wave of 2020 indicate that repeated international importations until late March were followed by a period of sustained community transmission that was consistent with a mass exodus from urban areas. A ban on international and domestic flights (21 March 2020) was probably the end point of international importations and 23 March marked the beginning of the expansion and dispersal of three dominant lineages in Bangladesh. The predicted introduction of SARS-CoV-2 into Bangladesh during mid-February is consistent with other global estimates that predicted that lineage B.1 was imported into Italy in late January but not detected until mid-February4,5.


Moreover, in an important differentiation from interventions that were in place during the first wave, the government of Bangladesh also imposed a restriction on intercity movement (beginning June 2021) to prevent mass migration disseminating SARS-CoV-2 and VOCs across Bangladesh.


The global incidence of VOCs has continued to rise linearly throughout 2021, and lessons learnt during initial waves in 2020 (such as spread through mass migration) must be applied to stem the curve of the ongoing pandemic and increasingly transmissible variants20. Our study shows what can be achieved locally as a result of international collaboration using continuous genomic surveillance. Our consortium is committed to continuing to provide information on SARS-CoV-2 as the situation develops to give the required support to the Government of Bangladesh as well as to any other similar country settings.

Internet and mobile providers have a responsibility in ensuring the privacy and safety of women using their services. It is imperative that they adequately inform users of available safety features such as privacy mechanisms. There should also be an effective redress mechanism that allows users to report violations they experience in social networks and that women should be involved in developing such a mechanism.


The Facebook cover photo size is 820 pixels wide by 312 pixels tall on desktop. However, mobile users will see 640 pixels wide by 360 pixels tall. The correct Facebook cover photo size is the first step to portraying the right image on social media.


Design, Setting, and Participants This longitudinal cohort study of 6595 participants from waves 1 (September 12, 2013, to December 14, 2014), 2 (October 23, 2014, to October 30, 2015), and 3 (October 18, 2015, to October 23, 2016) of the Population Assessment of Tobacco and Health study, a nationally representative cohort study of US adolescents, assessed US adolescents via household interviews using audio computer-assisted self-interviewing. Data analysis was performed from January 14, 2019, to May 22, 2019.
