Technology has played an important role in biological recording for hundreds of years, from the invention microscope to microprocessor. We review current and emerging technologies that are changing way we study record natural world. From websites smartphones, data capture is becoming easier, faster more accessible. Increases volume wider participation raises concerns over quality, which being addressed with accurate sensors, automated validation tools, verification platforms utilize expert...

Many countries introduced rubella-containing vaccination (RCV) after 2011, following changes in recommended World Health Organization (WHO) strategies and external support. We evaluated the impact of these introductions.We estimated country-specific, region-specific, global Congenital Rubella Syndrome (CRS) incidence during 1996-2019 using mathematical modeling, including routine campaign coverage seroprevalence data.In 2019, WHO African Eastern Mediterranean regions had highest CRS (64 [95%...

BackgroundThere have been declines in global immunisation coverage due to the COVID-19 pandemic. Recovery has begun but is geographically variable. This disruption led under-immunised cohorts and interrupted progress reducing vaccine-preventable disease burden. There have, so far, few studies of effects on vaccine effects. We aimed quantify vaccine-coverage routine campaign services, identify regions that could particularly benefit from catch-up activities, establish if losses effect be...

Marked reductions in the incidence of measles and rubella have been observed since widespread use vaccines. Although no global goal for eradication has established, all six WHO regions set elimination targets. However, a gap remains between current control levels targets, as shown by large outbreaks 2017 2019. We aimed to model potential globally inform report 73rd World Health Assembly on feasibility eradication.In this study, we modelled probability 2020 2100 under different vaccination...

Under certain conditions, sighted and blind humans can use echoes to discern characteristics of otherwise silent objects. Previous research concluded that robust horizontal-plane object localisation ability, without using head movement, depends on information above 2 kHz. While a strong interaural level difference (ILD) cue is available, it was not clear if listeners were or the monaural necessarily accompanies ILD. In this experiment, 13 normal-hearing asked identify right-vs.-left position...

Abstract Background The last two decades have seen substantial expansion of childhood vaccination programmes in low and middle income countries (LMICs). Here we quantify the health impact these by estimating deaths disability-adjusted life years (DALYs) averted with ten antigens 98 LMICs between 2000 2030. Methods Independent research groups provided model-based disease burden estimates under a range coverage scenarios for pathogens: hepatitis B (HepB), Haemophilus influenzae type b (Hib),...

The basic reproduction number ( R 0 ) of an infection determines the impact its control. For many endemic infections, is often estimated from appropriate country-specific seroprevalence data. Studies sometimes pool estimates same region for settings lacking data, but reliability this approach unclear. Plausibly, indicator-based approaches could predict such settings. We calculated rubella 98 and correlated value against 66 demographic, economic, education, housing health-related indicators....

The goal of this research is to establish an experimental technique that can accurately quantify and model the acoustics underlying echolocation process in bats. ultimate outcome such a direction would be ability determine pair pressure signals created at positions bat’s ears due reflected portion energy carried by given emission pulse (be it frequency-modulated pulse, constant-frequency or series clicks). these provide solid basis for investigation modelling relevant physiological aspects...

Some blind people use echoes to detect discrete, silent objects support their spatial orientation/navigation, independence, safety and wellbeing. The acoustical features that for this are not well understood. Listening changes in spectral shape due the presence of an object could be important detection avoidance, especially at short range, although it is currently known whether possible with echolocation-related sounds. Bands noise were convolved recordings binaural impulse responses...

Biodiversity monitoring using audio recordings is achievable at a truly global scale via large-scale deployment of inexpensive, unattended recording stations or by crowdsourcing and species recognition on mobile devices. The ability, however, to reliably identify vocalising animal limited the fact that acoustic signatures interest in such are typically embedded diverse complex background. To avoid problems associated with modelling backgrounds, we build generative models bird sounds use...

Active echolocation is a sensory modality possessed by variety of mammals and used for the identification, classification localization objects. A multi stage model bat process has been with recordings rotated disks to plot frequency spectrums signals reaching each bats' ears. Recordings from objects made within human audible range have also use in psychoacoustic experiments aimed at validating preliminary studies that shown some ability localize using echolocation.
