Limited Effects of Age on the Use of the Ankle and Counter-Rotation Mechanism in the Sagittal Plane
Authors: Van den Bogaart Maud , Bruijn Sjoerd , Spildooren Joke , Van Dieën Jaap , Meyns Pieter
Published: May 2023

During standing the center of mass (CoM) can be controlled relative to the base of support by applying ankle moments to shift the center of pressure (CoP mechanism). An additional mechanism is the counter-rotation mechanism, i.e., changing the angular momentum of segments around the CoM to change the direction of the ground reaction force. In this study, we assessed anteroposterior balance performance and the related use of these postural control mechanisms in children, younger and older adults. Sixteen children (6-9y), 17 younger adults (18-24y) and eight older adults (65-80y) performed bipedal upright standing trials of 16 seconds on a rigid surface and on three balance boards that could freely move in the sagittal plane, varying in height (15-19 cm). Full body kinematics were measured. Performance related outcome measures, i.e., the number of trials with balance loss and the Root Mean Square of the time series of the CoM acceleration (due to the CoP and counter-rotation mechanism) and the contributions of the CoP and counter-rotation mechanism to the CoM acceleration (in %) were calculated. Furthermore, selected kinematic measures, i.e., the orientation of the board and head and the Mean Power Frequency of board orientation and of CoM acceleration were calculated. Compared to younger adults, children and older adults showed a poorer balance performance. Across age groups and conditions, the contribution of the CoP mechanism to the total CoM acceleration was dominant, i.e., 95%-108%. The contribution of the counter-rotation mechanism was limited, i.e., 19%-31% (with totals higher than 100% indicating opposite effects of both mechanisms), since the counter-rotation mechanism would conflict with stabilizing the head in space. Furthermore, children did use the counter-rotation mechanism relatively more to accelerate the CoM compared to younger adults as they are possibly still learning to limit the contribution of the counter-rotation mechanism.
Critical Rationalism and Bayesianism
Authors: Olson Kent
Published: May 2023

Most accounts of the scientific method, e.g.s the Deductive-Nomological (D-N), Inductive Statistical (I-S), and so on, attempt to avoid Hume’s problem. Popper’s philosophy of critical rationalism and subjectivist Bayesianism come into conflict here on a number of points. The most noteworthy is on the problem of induction. That is, if science rests on induction (as Sir Francis Bacon would have it), and induction cannot be justified according to the strict demands of classical deductive validity without invoking a circularity, how can we say that science is rational? And how should scientists proceed? Bayesians utilizes a consistent multivalued logic that adheres to the Kolmogorov axioms. And on the other side, Sir Karl Popper maintains that the real logic of science is deductive. It is a myth that induction is even used. I will evaluate both claims through a third-party lens. That is, Micheal Ruse’ s epigenetic account of inferential reasoning. This is a modified version of Hume’s propensity theory. Ultimately, deductivism cannot explain how proto-humans behaved in the wild. How they grew smarter, became tool-using beings, and became the dominant species on the planet.

Authors: Bandyopadhyay Dr. Jatisankar , Karar Dipankar
Published: May 2023

Fire stations have to be situated carefully; in an emergency situation, the fire department should be able to reach its destination within time. The study exasperated to integrate Analytical Hierarchy Process (AHP) with Weighted Overlay analysis (WOA) in GIS to present a model for fire station location planning. The case study is carried out in the Asansol Sadar Subdivision of Paschim Bardhaman District, West Bengal, India. The study shows that there are 364.569 km2 of High-Risk Areas (most congested Settlements, industrial areas, and Coal Mining), 59.62 km2 of Moderate Risk, and 422.348 km2 of Low Risk. The results of this research introduce five sites that are most appropriate for establishing the new stations, which cover all the areas based on the fire response time, rules, and regulations. This analytical process considered densely populated shares of the cities and also the industrial neighborhoods in the Jamuria, Kulti – Barakar, Burnpur, Chittaranjan, and Churulia as mostly suitable zones for the new fire departments. The major advantages of the new proposed sites are accessibility to the accident-prone areas as per response time, setting in the most populated area of the zone, and the high potential for interventions, which can reduce the risk and loss of life and wealth.

ArmSpeech-POS: Eastern Armenian Part-of-Speech Tagged Corpus
Authors: Baghdasaryan Varuzhan H.
Published: May 2023

Text chunking, Part-of-speech (POS) tagging, and named entity recognition (NER) are fundamental tasks in natural language processing (NLP). Part-of-speech (POS) tagging involves assigning grammatical labels to words in a sentence. Research shows that Armenian is a low-resourced language and there are not enough materials for developing higher accurate part-of-speech tagging systems in the Armenian language. This paper presents a fresh dataset for POS tagging in Armenian that follows the naming conventions of both Penn Treebank and Universal Dependencies tagsets, with two versions available. The dataset consists of 6081 sentences that were automatically annotated and then manually verified. The data was sourced from Armenian news websites, focusing on topics such as culture, medicine, and lifestyle, as well as 22 Armenian fairytales. The reason for having two versions of the POS tagset was to ensure compatibility and integration with all-natural language processing tools and models that use these standards. By standardizing the tagset, it becomes easier to compare and evaluate the effectiveness of different POS tagging models. The paper also describes data collection, cleaning, preprocessing, and processing steps. The ISMA translator was used for the annotation of the dataset, which not only performs machine translation but also conducts a syntactic and semantic analysis of the text and assigns a POS tag for each word in the sentence. The final corpus contains 13 groups of part-of-speech tags and a total of 57160 tagged tokens including the distinction between singular and plural parts of speech.
Who speaks and who is heard on Facebook? Political mobilization and engagement patterns of partisanship and gender in Switzerland’s direct democracy
Authors: Maitra Julian , Hänggli Regula
Published: May 2023

This descriptive study investigates political mobilization and user engagement patterns on Facebook and associated partisan and gender discrepancies. It focuses on Switzerland, where political actors frequently seek to mobilize and shape citizens’ opinions before direct-democratic voting on wide-ranging policy issues. Using digital trace data from CrowdTangle, the analysis focuses on the posting frequency and received user interactions of 770 Swiss political actors’ Facebook pages. The analysis period covers 20 months, from November 2019 to July 2021, during which five popular votes occurred, and the sampled FB pages published more than 226,000 posts and received more than 18,000,000 user interactions. A descriptive quantitative analysis and a multiple regression analysis revealed an overall skewed pattern: Mobilization and user engagement are driven by small subsets of highly active and interacted-with FB pages. A few FB pages of the right-wing Swiss People’s Party and male politicians receive highly disproportionate user engagement – relative to more centrist parties and female politicians – but also relative to their electoral share in the national parliament. The results show that only a few dominant political voices are widely heard on Facebook, even if many speak. These insights are of interest beyond Switzerland, as Facebook and other social media platforms shape political discourse across liberal democracies.

Background One of fundamental components of general health and wellbeing is oral health. Among various oral diseases, periodontitis affects a large number of populations around the developed and underdeveloped countries of the world. The first step to manage this disease at the community level is to know its prevalence and trend. Therefore, this systematic review was planned to document the prevalence of periodontitis at the national and regional level.

Methods Literature was searched using various databases, such as PubMed, Google Scholar, Pak Medi net and Eric. Keywords used were “Prevalence”, “Periodontitis”, “Pakistan” “Prevalence of periodontitis in Pakistan”, “prevalence and/or periodontitis and/or Pakistan”. The research methodology was based on the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) to extract and later analyze relevant studies. Quality assessment of all the included studies was performed using Joanna Briggs Institute (JBI) critical appraisal checklist.

Results Thirty studies that fulfilled the inclusion criteria and reported the prevalence of periodontitis in the Pakistani population were included. A total of 17,757 subjects were included in the systematic review from 30 studies. The prevalence estimate of periodontitis (keeping 95%CI) was 37% from Punjab, 40% from Sindh, 20% from Khyber Pakhtunkhwa and 3% from Baluchistan.

Conclusion Based on our collection of data prevalence of periodontitis in Pakistan was found to be high. Therefore, it can be concluded that in Pakistan periodontitis is a serious dental issue that must be sorted out to improve the oral health related quality of life in this demographic part. This paper will serve as a baseline for planning future health policies to address this disease in the country.

Published: May 2023

Objective: To assess the understanding and knowledge of medical students regarding COVID-19 and to determine their ability in applying that knowledge as they could serve as potential workforce.

Methods: A quantitative approach was used to evaluate the knowledge of the medical students. The data was collected by an online cross-sectional survey conducted among students from 9 medical colleges across all provinces of Pakistan. The sample included 627 respondents. The survey was divided into two parts, the web-based information that a medical student acquires by self-motivation and information derived from social media that needs critical evaluation and further research to determine its authenticity. The second part included evaluation of knowledge about the pandemic in general with a focus on COVID-19 and its application. 

Results: There were a total of 627 respondents from medical colleges across Pakistan. The majority 98.1% (n=615) were aware of pandemic and 87% (n=546) were actively following the emerging evidence of COVID-19. An important feature was that 82.8% (n=519) of the medical students were willing to check for the authenticity of information. More than two third of medical students had adequate knowledge regarding importance of testing, vulnerable population and protective measures required to prevent spread of COVID-19. Respondents responded to observing the preventive measures with 91% observing social distancing, 86% maintaining personal hygiene and 72% wearing masks.                                                                                                  

Conclusions: Most of the medical students in Pakistan keep themselves abreast with developments in the pandemic. They are capable of understanding the scientific basis behind COVID-19 and have the ability to differentiate between scientific and nonscientific information.

An athlete suffers from many injuries in his sports career which may be due to some trauma or maybe atraumatic. Athletes involved in the sports of long-running remains worried about knee osteoarthritis (O.A) and a question always remain in a debate that physical activity is a risk of O.A and the athletes are running for osteoarthritis. This systematic review was conducted to synthesize the evidence on the quantitative association between participation in specific sports and the occurrence of Knee OA. This systematic review will also analyze the effect of sports injuries on knee OA.

Methods

Three electronic databases including PubMed, Scopus, and Springer link are selected for gathering the information and the articles for this study. This systematic review is based on the randomized control trials (RCTs), cohort and case-control studies published in the last 20 years (2000-2022) evaluating the symptomatic or asymptomatic tibiofemoral knee osteoarthritis change. The quality for study methodology was evaluated by using the Cochrane Effective Practice and Organization of Care Risk of Bias Tool and PRISMA checklist as a reference. Review manager, 5.4.1 Cochrane Collaboration was used for analyzing the risk for bias of individual studies.

Results

A total of 508 articles were searched and nine articles were selected to synthesized the results of this systematic review. Total nine articles are selected to conclude the results based on the inclusion criteria. Graph 1 is showing the study design and the number of included and excluded articles. The results are synthesized on the following levels using the PICOS model, i) comparison of running sports and incidence of knee osteoarthritis, ii) comparison of soccer, gender, and incidence of knee osteoarthritis, iii) comparison of anterior cruciate injury, the effect of treatment and incidence of knee osteoarthritis, and iv) comparison of training and prevention of knee osteoarthritis incidence.

Conclusion

Sports with more jumping, twisting, and knee injuries contribute to the prevalence of knee osteoarthritis. Knee osteoarthritis in athletes remains asymptomatic initially and it manifested after 15 to 20 years after the start of pathogenesis due to some knee injury, especially ACL and menisci injury.

Abstract. This study analyzes turbulent energy fluxes in the Arctic atmospheric boundary layer (ABL) using measurements with a small uncrewed aircraft system (sUAS). Turbulent fluxes constitute a major part of the atmospheric energy budget and influence the surface heat balance by distributing energy vertically in the atmosphere. However, only few in situ measurements of the vertical profile of turbulent fluxes in the Arctic ABL exist. The study presents a method to derive turbulent heat fluxes from DataHawk2 sUAS turbulence measurements, based on the flux gradient method with a parameterization of the turbulent exchange coefficient. This parameterization is derived from high-resolution horizontal wind speed measurements in combination with formulations for the turbulent Prandtl number and anisotropy depending on stability. Measurements were taken during the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) expedition in the Arctic sea ice during the melt season of 2020. For three example cases from this campaign, vertical profiles of turbulence parameters and turbulent heat fluxes are presented and compared to balloon-borne, radar, and near-surface measurements. The combination of all measurements draws a consistent picture of ABL conditions and demonstrates the unique potential of the presented method for studying turbulent exchange processes in the vertical ABL profile with sUAS measurements.

Abstract. Fine particulate matter (PM2.5) samples were collected between November 2020 and October 2021 at the Minzu University of China in Beijing and the n-alkyl nitrate concentrations in the PM2.5 samples were determined to investigate n-alkyl nitrate pollution and formation mechanisms. C9–C16 n-alkyl nitrate standards were synthesized and the n-alkyl nitrate concentrations in PM2.5 were determined by gas chromatography triple quadrupole mass spectrometry. Temporal trends in and correlations between particulate-bound n-alkyl nitrate, ozone, PM2.5, and nitrogen dioxide concentrations were investigated to assess the relationships between particulate-bound n-alkyl nitrate concentrations and photochemical reactions and identify the n-alkyl nitrate formation mechanisms. The n-alkyl nitrate concentrations in the PM2.5 samples were 9.67–2730 pg/m3, and the mean was 578 pg/m3. The n-alkyl nitrate homologue group concentrations increased as the carbon chain length increased, i.e, long-chain n-alkyl nitrates contributed more than short-chain n-alkyl nitrates to the total n-alkyl nitrate concentrations in PM2.5. The n-alkyl nitrate concentrations clearly varied seasonally and diurnally, the concentrations decreasing in the order winter > spring > autumn > summer and the mean concentrations being higher at night than in the day. The particulate-bound n-alkyl nitrate and ozone concentrations significantly negatively correlated despite gas-phase alkyl nitrate and ozone concentrations previously being found to positively correlate. This indicated that long-chain alkyl nitrates may not be produced during photochemical reactions. The particulate-bound n-alkyl nitrate concentrations followed the same trends as and significantly positively correlated with the PM2.5 and nitrogen dioxide concentrations. Nitrogen dioxide is an important contributor of nitrates in particulate matter. This indicated that particulate-bound n-alkyl nitrates may form through reactions between alkanes and nitrates on particulate matter surfaces. Particulate-bound n-alkyl nitrates are important components of PM2.5 during haze events and strongly affect atmospheric visibility. Particulate-bound n-alkyl nitrates are secondary pollutants that strongly influence haze pollution.

Abstract. Few studies have investigated the impact of new particle formation (NPF) on cloud condensation nuclei (CCN) in remote Antarctica, and none has elucidated the relationship between NPF and CCN production. To address that knowledge gap, we continuously measured the number size distribution of 2.5–300 nm particles and CCN number concentrations at King Sejong Station in the Antarctic Peninsula from January 1 to December 31, 2018. Ninety-seven new particle formation (NPF) events were detected throughout the year. The estimated median spatial scale of NPF around Antarctic peninsula was found to be approximately 155 km, indicating the large-scale of NPF events. Air back-trajectory analysis revealed that 80 cases of NPF events were associated with air masses originating over the ocean, followed by sea ice (12 cases), multiple (3 cases), and land (2 cases) regions. We present and discuss three major NPF categories: (1) marine NPF (2) sea ice NPF, and (3) multiple NPF. Our results showed that the photo-oxidation of oceanic biogenic precursors such as dimethyl sulfide (DMS) could be a key component in marine NPF events, whereas halogen compounds released from ice-covered areas could contribute to sea-ice NPF events. Terrestrial sources (wild life colonies, vegetation, and meltwater ponds) from Antarctica could affect aerosol production in multiple air masses. Out of 97 observed NPF events, 83 cases were characterized by the simultaneous increase in the CCN concentration by 2–270 % (median 44 %) in the following 1 to 36 hours (median 8 hours) after NPF events. Overall, Antarctic NPF events were found to be a significant source of particles with different physical characteristics and related to biogenic sources in and around the Antarctic Peninsula, which subsequently grew to cloud nuclei.
A practical method for assigning uncertainty and improving the accuracy of alpha-ejection corrections and eU concentrations in apatite (U–Th) ∕ He chronology

Published: May 2023

Abstract. Apatite (U–Th) / He (AHe) dating generally assumes that grains can
be accurately and precisely modeled as geometrically perfect hexagonal
prisms or ellipsoids in order to compute the apatite volume (V),
alpha-ejection corrections (FT), equivalent spherical radius
(RFT), effective uranium concentration (eU), and corrected (U–Th) / He
date. It is well-known that this assumption is not true. In this work, we
present a set of corrections and uncertainties for V, FT, and RFT
aimed (1) at “undoing” the systematic deviation from the idealized
geometry and (2) at quantifying the contribution of geometric uncertainty to
the total uncertainty budget for eU and AHe dates. These corrections and
uncertainties can be easily integrated into existing laboratory workflows at
no added cost, can be routinely applied to all dated apatite, and can even
be retroactively applied to published data. To quantify the degree to which
real apatite deviates from geometric models, we selected 264 grains that span
the full spectrum of commonly analyzed morphologies, measured their
dimensions using standard 2D microscopy methods, and then acquired 3D scans
of the same grains using high-resolution computed tomography (CT). We then
compared our apatite 2D length, maximum width, and minimum width
measurements with those determined by CT, as well as the V, FT, and
RFT values calculated from 2D microscopy measurements with those from
the “real” 3D measurements. While our 2D length and maximum width
measurements match the 3D values well, the 2D minimum width values
systematically underestimate the 3D values and have high scatter. We
therefore use only the 2D length and maximum width measurements to compute
V, FT, and RFT. With this approach, apatite V, FT, and
RFT values are all consistently overestimated by the 2D microscopy
method, requiring correction factors of 0.74–0.83 (or 17 %–26 %), 0.91–0.99
(or 1 %–9 %), and 0.85–0.93 (or 7 %–15 %), respectively. The 1σ
uncertainties in V, FT, and RFT are 20 %–23 %, 1 %–6 %, and
6 %–10 %, respectively. The primary control on the magnitude of the
corrections and uncertainties is grain geometry, with grain size exerting
additional control on FT uncertainty. Application of these corrections
and uncertainties to a real dataset (N=24 AHe analyses) yields 1σ
analytical and geometric uncertainties of 15 %–16 % in eU and 3 %–7 % in the
corrected date. These geometric corrections and uncertainties are
substantial and should not be ignored when reporting, plotting, and
interpreting AHe datasets. The Geometric Correction Method (GCM) presented
here provides a simple and practical tool for deriving more accurate FT
and eU values and for incorporating this oft neglected geometric
uncertainty into AHe dates.

Abstract. Wildfires change the hydrologic and geomorphic response of watersheds, which has been associated with cascades of additional hazards and management challenges. Among these post-wildfire events are shallow landslides and debris flows. This study evaluates post-wildfire mass movement trigger characteristics by comparing the precipitation preceding events at both burned and unburned locations. Landslide events are selected from the NASA Global Landslide Catalog (GLC). Since this catalog contains events from multiple regions worldwide, it allows a greater degree of inter-region comparison than many more localized catalogs. Fire and precipitation histories for each site are established using Moderate Resolution Imagine Spectroradiometer (MODIS) Burned Area and Climate Hazards group InfraRed Precipitation with Station data (CHIRPS) precipitation data, respectively. Analysis of normalized 7 d accumulated precipitation for sites across all regions shows that, globally, mass movements at burned sites are preceded by less precipitation than mass movements without antecedent burn events. This supports the hypothesis that fire increases rainfall-driven mass movement hazards. An analysis of the seasonality of mass movements at burned and unburned locations shows that mass-movement-triggering storms in burned locations tend to exhibit different seasonality from rainfall-triggered mass movements in areas undisturbed by recent fire, with a variety of seasonal shifts ranging from approximately 6 months in the Pacific Northwest of North America to 1 week in the Himalayan region. Overall, this paper offers an exploration of regional differences in the characteristics of rainfall-triggered mass movements at burned and unburned sites over a broad spatial scale and encompassing a variety of climates and geographies.
