Abstract: Developing an understanding of the public discourse on COVID-19 vaccination on social media is important not only for addressing the ongoing COVID-19 pandemic but also for future pathogen outbreaks. There are various research efforts in this domain, although, a need still exists for a comprehensive topic-wise analysis of tweets in favor of and against COVID-19 vaccines. This study characterizes the discussion points in favor of and against COVID-19 vaccines posted on Twitter during the first year of the pandemic. The aim of this study was primarily to contrast the views expressed by both c s, their respective activity patterns, and their correlation with vaccine-related events. A further aim was to gauge the genuineness of the concerns expressed in antivax tweets. We examined a Twitter data set containing 75 million English tweets discussing the COVID-19 vaccination from March 2020 to March 2021. We trained a stance detection algorithm using natural language processing techniques to classify tweets as antivax or provax and examined the main topics of discourse using topic modeling techniques. Provax tweets (37 million) far outnumbered antivax tweets (10 million) and focused mostly on vaccine development, whereas antivax tweets covered a wide range of topics, including opposition to vaccine mandate and concerns about safety. Although some antivax tweets included genuine concerns, there was a large amount of falsehood. Both stances discussed many of the same topics from opposite viewpoints. Memes and jokes were among the most retweeted messages. Most tweets from both stances (9,007,481/10,566,679, 85.24% antivax and 24,463,708/37,044,507, 66.03% provax tweets) came from dual-stance users who posted both provax and antivax tweets during the observation period. This study is a comprehensive account of COVID-19 vaccine discourse in the English language on Twitter from March 2020 to March 2021. The broad range of discussion points covered almost the entire conversation, and their temporal dynamics revealed a significant correlation with COVID-19 vaccine–related events. We did not find any evidence of polarization and prevalence of antivax discourse over Twitter. However, targeted countering of falsehoods is important because only a small fraction of antivax discourse touched on a genuine issue. Future research should examine the role of memes and humor in driving web-based social media activity.

Abstract: Mild cognitive impairment (MCI) patients report memory problems greater than those normally expected with ageing, but do not fulfil criteria for clinically probable Alzheimer's disease. Accumulating evidence demonstrates that impaired performance on the Paired Associates Learning (PAL) test from the Cambridge Neuropsychological Test Automated Battery (CANTAB) may be sensitive and specific for early and differential diagnosis of Alzheimer's disease. We adapted the basic CANTAB PAL task for functional magnetic resonance imaging (fMRI) in order to examine the functional brain deficits, at encoding and retrieval separately, in patients with MCI compared to healthy matched volunteers. As well as investigating the main effects of encoding and retrieval, we characterized neural responses in the two groups to increasing memory load. We focused on changes in BOLD response in the hippoc us and related structures, as an a priori region of interest based on what is known about the neuropathology of the early stages of Alzheimer's disease and previous information on the neural substrates of the PAL task. We also used structural MRI in the same patients to assess accompanying structural brain abnormalities associated with MCI. In terms of the BOLD response, the bilateral hippoc al activation in the MCI and control groups depended upon load, the MCI patients activating significantly more than controls at low loads and significantly less at higher loads. There were no other differences between MCI patients and controls in terms of the neural networks activated during either encoding or retrieval of the PAL task, including the prefrontal, cingulate and temporal cortex. The functional deficit in hippoc al activation in the MCI patients was accompanied by structural differences in the same location, suggesting that the decrease in hippoc al activation may be caused by a decrease in the amount of grey matter. This is one of the first studies to have used both encoding and retrieval phases of a memory paradigm for fMRI in MCI patients, and to have shown that the BOLD response in MCI patients can show both hyperactivation and hypoactivation in the same in iduals as a function of memory load and encoding/retrieval. The findings suggest that performance on PAL might be a useful cognitive biomarker for early detection of Alzheimer's disease, especially when used in conjunction with neuroimaging.

Abstract: In this work, we implemented line-of-sight (LoS) ray tracing functionality to investigate problems in millimetre-wave propagation modelling and network planning in 3D city model environments. First, we validated an existing LoS propagation probability model expressed as an exponential rule with the link distance. By fitting ray tracing simulation results under different scenarios to the model, the relationships between key parameters in the model and factors including the building density and the transmitter height were qualitatively analysed. Next, we developed a network planning framework for a multi-hop outdoor urban network by formulating a mixed-integer linear programming problem which minimises the overall deployment cost through optimal site selection. Taking the sets of potential site locations and potential links as inputs, we selected a subset of the sites that comprise a tree-structured network that satisfies all the user demands at a minimum deployment cost. We also analysed the time required for solving this optimisation problem in order to provide a prediction of the execution time for larger-sized problems.

Abstract: We explore the potential of chromatic dispersion and polarization-mode dispersion (PMD) mitigation using Viterbi equalization in 10 Gb/s nonreturn-to-zero differential phase-shift keying (NRZ-DPSK) and differential quadrature phase-shift keying (NRZ-DQPSK) systems. We show through Monte Carlo simulations that using Viterbi equalization improves the performance of NRZ-OOK, NRZ-DPSK and NRZ-DQPSK receivers. For NRZ-DQPSK receiver with a Viterbi equalizer, the chromatic dispersion tolerance is about 5000 ps/nm and the 1st order PMD tolerance is about 160 ps at 3 dB OSNR penalty.
