Privacy-Preserving Synthetic Continual Semantic Segmentation for Robotic Surgery.

Deep Neural Networks (DNNs) based semantic segmentation of the robotic instruments and tissues can enhance the precision of surgical activities in robot-assisted surgery. However, in biological learning, DNNs cannot learn incremental tasks over time and exhibit catastrophic forgetting, which refers to the sharp decline in performance on previously learned tasks after learning a new one. Specifically, when data scarcity is the issue, the model shows a rapid drop in performance on previously learned instruments after learning new data with new instruments. The problem becomes worse when it limits releasing the dataset of the old instruments for the old model due to privacy concerns and the unavailability of the data for the new or updated version of the instruments for the continual learning model. For this purpose, we develop a privacy-preserving synthetic continual semantic segmentation framework by blending and harmonizing (i) open-source old instruments foreground to the synthesized background without revealing real patient data in public and (ii) new instruments foreground to extensively augmented real background. To boost the balanced logit distillation from the old model to the continual learning model, we design overlapping class-aware temperature normalization (CAT) by controlling model learning utility. We also introduce multi-scale shifted-feature distillation (SD) to maintain long and short-range spatial relationships among the semantic objects where conventional short-range spatial features with limited information reduce the power of feature distillation. We demonstrate the effectiveness of our framework on the EndoVis 2017 and 2018 instrument segmentation dataset with a generalized continual learning setting.

The annual update GLODAPv2.2023: the global interior ocean biogeochemical data product

Abstract. The Global Ocean Data Analysis Project (GLODAP) is a synthesis effort providing regular compilations of surface to bottom ocean biogeochemical bottle data, with an emphasis on seawater inorganic carbon chemistry and related variables determined through chemical analysis of seawater samples. GLODAPv2.2023 is an update of the previous version, GLODAPv2.2022 (Lauvset et al., 2022). The major changes are as follows: data from 23 new cruises were added. In addition, a number of changes were made to the data included in GLODAPv2.2022. GLODAPv2.2023 includes measurements from more than 1.4 million water samples from the global oceans collected on 1108 cruises. The data for the now 13 GLODAP core variables (salinity, oxygen, nitrate, silicate, phosphate, dissolved inorganic carbon, total alkalinity, pH, chlorofluorocarbon-11 (CFC-11), CFC-12, CFC-113, CCl4, and SF6) have undergone extensive quality control with a focus on the systematic evaluation of bias. The data are available in two formats: (i) as submitted by the data originator but converted to World Ocean Circulation Experiment (WOCE) exchange format and (ii) as a merged data product with adjustments applied to minimize bias. For the present annual update, adjustments for the 23 new cruises were derived by comparing those data with the data from the 1085 quality-controlled cruises in the GLODAPv2.2022 data product using crossover analysis. SF6 data from all cruises were evaluated by comparison with CFC-12 data measured on the same cruises. For nutrients and ocean carbon dioxide (CO2), chemistry comparisons to estimates based on empirical algorithms provided additional context for adjustment decisions. The adjustments that we applied are intended to remove potential biases from errors related to measurement, calibration, and data-handling practices without removing known or likely time trends or variations in the variables evaluated. The compiled and adjusted data product is believed to be consistent to better than 0.005 in salinity, 1 % in oxygen, 2 % in nitrate, 2 % in silicate, 2 % in phosphate, 4 µmol kg−1 in dissolved inorganic carbon, 4 µmol kg−1 in total alkalinity, 0.01–0.02 in pH (depending on region), and 5 % in the halogenated transient tracers. The other variables included in the compilation, such as isotopic tracers and discrete CO2 fugacity (fCO2), were not subjected to bias comparison or adjustments. The original data, their documentation, and DOI codes are available at the Ocean Carbon and Acidification Data System of NOAA National Centers for Environmental Information (NCEI), which also provides access to the merged data product. This is provided as a single global file and as four regional ones – the Arctic, Atlantic, Indian, and Pacific oceans – under https://doi.org/10.25921/zyrq-ht66 (Lauvset et al., 2023). These bias-adjusted product files also include significant ancillary and approximated data, which were obtained by interpolation of, or calculation from, measured data. This living data update documents the GLODAPv2.2023 methods and provides a broad overview of the secondary quality control procedures and results.

Assessing the performance of a radioactive waste repository over geological timescales: past experience and the way forward

The successful implementation of plans to develop a repository for radioactive waste in the United Kingdom will require an assessment of the ability of the facility to meet appropriate regulatory safety criteria at all stages during its construction, operation and after closure. As part of this assessment, an environmental safety case (ESC) will be presented and this will contain a collection of claims, arguments and evidence which collectively demonstrate that long-term safety can be achieved and maintained. Natural analogues (NA) can be helpful in demonstrating understanding of aspects of repository performance by, for example, providing evidence that certain materials can survive for long periods. Appropriate NAs can be critical to providing long-term practical demonstrations to support the theoretical and mathematical arguments of the ESC and they may have a significant role in the overall process understanding. As part of the ongoing repository development programme in the UK, an updated version of an existing catalogue of NA studies (focussed on the requirements of the ESC) has been produced and the background to NA studies in general, and to the catalogue in particular, are presented here. Thematic collection: This article is part of the Sustainable geological disposal and containment of radioactive waste collection available at: https://www.lyellcollection.org/topic/collections/radioactive

Scaling up and implementing the digital Survivorship Passport tool in routine clinical care – The European multidisciplinary PanCareSurPass project

BackgroundChildhood cancer survivors (CCS), of whom there are about 500,000 living in Europe, are at an increased risk of developing health problems [1–6] and require lifelong Survivorship Care. There are information and knowledge gaps among CCS and healthcare providers (HCPs) about requirements for Survivorship Care [7–9] that can be addressed by the Survivorship Passport (SurPass), a digital tool providing CCS and HCPs with a comprehensive summary of past treatment and tailored recommendations for Survivorship Care. The potential of the SurPass to improve person-centred Survivorship Care has been demonstrated previously [10,11]. MethodsThe EU-funded PanCareSurPass project will develop an updated version (v2.0) of the SurPass allowing for semi-automated data entry and implement it in six European countries (Austria, Belgium, Germany, Italy, Lithuania and Spain), representative of three infrastructure healthcare scenarios typically found in Europe. The implementation study will investigate the impact on person-centred care, as well as costs and processes of scaling up the SurPass. Interoperability between electronic health record systems and SurPass v2.0 will be addressed using the Health Level Seven (HL7) International interoperability standards. ResultsPanCareSurPass will deliver an interoperable digital SurPass with comprehensive evidence on person-centred outcomes, technical feasibility and health economics impacts. An Implementation Toolkit will be developed and freely shared to promote and support the future implementation of SurPass across Europe. ConclusionsPanCareSurPass is a novel European collaboration that will improve person-centred Survivorship Care for CCS across Europe through a robust assessment of the implementation of SurPass v2.0 in different healthcare settings.

Reliability testing of the Health of the Nation Outcome Scales 2018.

The Health of the Nation Outcome Scales (HoNOS) is a widely used clinical measure designed to rate and monitor the outcomes of service users accessing specialist mental healthcare. Since its development (in 1996), numerous research studies have confirmed the HoNOS captures the aspects of care that it purports to (validity), and that clinicians' ratings are consistent both over time, and between different raters (reliability). In 2018, the HoNOS was reviewed with updates made to some terminology and other revisions intended to remove ambiguity in the guidance for raters. However, although the new version (HoNOS 2018) was accompanied by a recommendation that its validity and reliability be re-tested this was not undertaken. To our knowledge, this is the first study to re-assess the updated tool's reliability by measuring the level of agreement between different raters. Our findings confirm that there is an acceptable level of consistency between student mental health nurses that have been trained to use the (new) HoNOS 2018. The HoNOS is nationally mandated for use by all specialist mental healthcare providers in the UK. Our findings provide some assurance that, with appropriate update training and monitoring of organisational-level data sets, the original HoNOS glossary can safely be replaced with the HoNOS 2018 to ensure more contemporary routine outcome measurement can occur. INTRODUCTION: The Health of the Nation Outcome Scales (HoNOS) is a well-established clinician rated outcome measure for use in mental health services. Following an international review, an updated version (HoNOS 2018) was published with a recommendation that its psychometric properties be re-tested prior to widespread implementation. To date, only one such study has been published. To test the inter-rater agreement levels for HoNOS 2018. Third-year student mental health nurses received training to complete the HoNOS 2018. Following this timetabled session, they were each invited to independently rate two, randomly selected, videos of (simulated) patient interviews. The resulting data were then analysed to calculate the tool's internal consistency and inter-rater agreement levels. The 55 participants provided 106 ratings from four vignettes. Cronbach's alphas and McDonalds omegas confirmed the revised tool's internal consistency was acceptable. Average measure intraclass correlation coefficients for the four patient vignettes indicated excellent reliability. This study provides initial assurance that the HoNOS 2018 is a reliable clinician rated outcome measure suitable for use in routine clinical practice by relatively inexperienced mental health practitioners with limited training.

Design and analysis of ELM-based predefined time sliding mode adaptive controller for PMLM position control under physical constraints

Achieving accurate position tracking for robotics and industrial servo systems is an extremely challenging task, particularly when dealing with control saturation, parameter perturbation, and external disturbance. To address these challenges, a predefined time convergent sliding mode adaptive controller (PTCSMAC) has been proposed for a permanent magnet linear motor (PMLM). A novel sliding mode surface (SMS) with predefined time convergence PDTC has been constructed, which ensures that the error converges to zero within the prescribed time. The system not only meets the expected performance standards but also has a uniformly bounded motor speed. The trajectory tracking error in SMS is proven to converge to zero within the predefined time. This predefined time stability of the closed-loop system has been demonstrated by using the Lyapunov stability criterion with PDTC. The convergence time (CT) can be arbitrarily set, and the upper bound of it is not affected by the initial value and control parameters of the system. A new updated version of extreme learning machine (ELM) is introduced to approximate the uncertain part of the system based on PDTC. The ELM is also provided with the hyperbolic tangent function to estimate the saturation constraint. This is done by converting the function into a linear function concerning the unconstrained control input variable. Then, based on established stability, a novel sliding mode adaptive controller (PTCSMAC) with predefined time convergence is designed. The convergence time (CT) of the controller is unaffected by the initial conditions as well as the control parameters. The rigorous numerical simulations on the PMLM model with complex disturbances verify the strong robustness and high-precision tracking characteristic of the proposed control law.

Wilderness Medical Society Clinical Practice Guidelines for the Prevention and Treatment of Heat Illness: 2024 Update.

The Wilderness Medical Society (WMS) convened an expert panel in 2011 to develop a set of evidence-based guidelines for the recognition, prevention, and treatment of heat illness. The current panel retained 5 original members and welcomed 2 new members, all of whom collaborated remotely to provide an updated review of the classifications, pathophysiology, evidence-based guidelines for planning and preventive measures, and recommendations for field- and hospital-based therapeutic management of heat illness. These recommendations are graded based on the quality of supporting evidence and the balance between the benefits and risks or burdens for each modality. This is an updated version of the WMS clinical practice guidelines for the prevention and treatment of heat illness published in Wilderness & Environmental Medicine. 2019;30(4):S33-S46.

Baba is Y'all 2.0: Design and Investigation of a Collaborative Mixed-Initiative System

This paper describes a new version of the mixed-initiative collaborative level designing system: Baba is Y'all, as well as the results of a user study on the system. Baba is Y'all is a prototype for AI-assisted game design in collaboration with others. The updated version includes a more user-friendly interface, a better level-evolver and recommendation system, and extended site features. The system was evaluated via a user study where participants were required to play a previously submitted level from the site and then create their own levels using the editor. They reported on their individual process creating the level and their overall experience interacting with the site. The results have shown both the benefits and limitations of this mixed-initiative system and how it can help with creating a diversity of ‘Baba is You’ levels that are both human and AI designed while maintaining their quality.

Virtues and vocation: An historical perspective on scientific integrity in the twenty-first century

According to the Dutch chemist Gerrit Jan Mulder (1802–1880), the principal aim of university education was character building and moral edification. Professional training was of secondary importance. Mulder’s ideas about the vocation and moral mission of the university professor can serve as a historical counterpart to later Weberian, Mertonian, and contemporary ideas on the ethos of science. I argue that a revaluation of the moral precepts that Mulder saw as defining the life of an academic is helpful in dealing with the problems of late modern science, such as the replication crisis and research misconduct. Addressing such problems must start in the university classrooms. To empower students to internalize the principles of responsible conduct of research, we need an updated version of Mulder’s idea of the university professor as a moral agent.

The effectiveness of a school-based phonics instructional material

The updated version of the national English curriculum for compulsory education was released in 2022. In this updated version, phonics was also required. Although studies about phonics were uprising again after the release of the new curriculum, most of the previous studies did not specify phonics instruction approach or obtain a larger sample size. Besides, previous studies called for a school-based phonics instructional material to enhance English as a foreign language (EFL) beginners’ word recognition ability at word level. To bridge the gap, the researchers compiled a phonics instructional material based on synthetic phonics approach in light of the new national English curriculum and bottom-up reading model. To evaluate the effectiveness of such a phonics material, a number of 366 EFL students from three strata across two schools participated in this quasi-experiment via stratified random sampling technique. They experienced a pre-test, 16 weeks of training via the phonics material, a post-test as well as a delayed retention test, which was held three months later. The results of both independent t-test and paired samples t-test have indicated that the newly compiled phonics material can improve EFL students’ word recognition ability up to 50% and that the knowledge was well-retained after a period of time as practices went on. The results have further implied that to better implement phonics instruction and to radically improve EFL students’ reading ability, the solution might be to assign time in the extra-curriculum service to teach phonics via explicit and systematic synthetic phonics instruction tailored according to the school-based phonics material.

Assessment of radiation environmental risks for fish fauna of the cooling pools of a number of operating nuclear power plants

Relevance. The need to assess radiation risks for the main types of fish in pools that are under the constant influence of the nuclear power plants. Aim. To assess the radiation environmental risks for the ichthyofauna of cooling pools of the operating nuclear power plants, to analyze the sources and features of formation of the radiation risks at different stages of their operation. Objects: monitoring studies of radiation environmental risks for reference fish species in cooling reservoirs of the Leningrad, Beloyarsk and Novovoronezh NPP. Methods. Calculation of the exposure dose rate and quantitative assessment of the risk of exposure to technogenic radionuclides of the ichthyofauna of the cooling pools of the Beloyarskaya, Leningradskaya and Novovoronezhskaya NPPs were carried out using the international computer complex of the updated version of ERICA Tool 2.0. Results. The paper demonstrates that the radiation ecological risks for the ichthyofauna in the cooling pools of the operating nuclear power plants are caused by the combined effect of radioisotopes of the different origin. The features of the formation of the radiation risks for each pool are specific and depend on the current radiation situation. The cooling pool of the Beloyarskaya NPP is characterized by a pronounced dependence of the radiation load on the types of operating power units. The ichthyofauna experienced the greatest radiation risks during the operation of the first two power units with thermal reactors AMB-100 and AMB-200. The decommissioning of the first power units and the construction of the units with the fast neutron reactors (BN-600 and BN-800) led to a significant reduction in the radiation load on the ichthyofauna of the cooling pool. At present, the radiation risks are caused mainly by the influence of 90Sr, which is almost not discharged from the Beloyarskaya NPP into the cooling pools, but has a predominantly global origin. Therefore, the formation of the risks is more associated with atmospheric fallout of 90Sr, and not with the operation of the nuclear power plant. The radiation risks for the ichthyofauna of the Leningradskaya NPP cooling pool are caused by the combined effect of 137Cs as a result of the radiation accident at the Chernobylskaya NPP and radionuclides with induced activity (14C; 60Co; 3H 54Mn and 65Zn), the origin of which may be associated with the operation of the nuclear reactors of the NPP. The level of radiation risk for the fish fauna of the Novovoronezhskaya NPP cooling pool for 2009–2019 increased 2.2 times due to an increase in the content of 60Co in many components of the pool. As a result, 81.7% of the radiation risks in demersal fish species were formed by the influence of 60Co. It cannot be ruled out that the increase in the 60Co content in the cooling pool of the Novovoronezhskaya NPP is a consequence of radioactive contamination of the groundwater as a result of the 1985 accident. The ecological risks for the fish fauna in all cooling pools are two to three orders of magnitude lower than the maximum allowable hazard coefficient. Thus, the normal operation of the nuclear power plants does not create unacceptable radiation risks that pose a real environmental threat to the fish fauna of the cooling pools.

QTL analysis of femaleness in monoecious spinach and fine mapping of a major QTL using an updated version of chromosome-scale pseudomolecules.

Although spinach is predominantly dioecious, monoecious plants with varying proportions of female and male flowers are also present. Recently, monoecious inbred lines with highly female and male conditions have been preferentially used as parents for F1-hybrids, rather than dioecious lines. Accordingly, identifying the loci for monoecism is an important issue for spinach breeding. We here used long-read sequencing and Hi-C technology to construct SOL_r2.0_pseudomolecule, a set of six pseudomolecules of spinach chromosomes (total length: 879.2 Mb; BUSCO complete 97.0%) that are longer and more genetically complete than our previous version of pseudomolecules (688.0 Mb; 81.5%). Three QTLs, qFem2.1, qFem3.1, and qFem6.1, responsible for monoecism were mapped to SOL_r2.0_pseudomolecule. qFem3.1 had the highest LOD score and corresponded to the M locus, which was previously identified as a determinant of monoecious expression, by genetic analysis of progeny from female and monoecious plants. The other QTLs were shown to modulate the ratio of female to male flowers in monoecious plants harboring a dominant allele of the M gene. Our findings will enable breeders to efficiently produce highly female- and male-monoecious parental lines for F1-hybrids by pyramiding the three QTLs. Through fine-mapping, we narrowed the candidate region for the M locus to a 19.5 kb interval containing three protein-coding genes and one long non-coding RNA gene. Among them, only RADIALIS-like-2a showed a higher expression in the reproductive organs, suggesting that it might play a role in reproductive organogenesis. However, there is no evidence that it is involved in the regulation of stamen and pistil initiation, which are directly related to the floral sex differentiation system in spinach. Given that auxin is involved in reproductive organ formation in many plant species, genes related to auxin transport/response, in addition to floral organ formation, were identified as candidates for regulators of floral sex-differentiation from qFem2.1 and qFem6.1.

Reported Decreases in Diversity, Equity, and Inclusion Practices in Environmental Education Organizations

Background: STEM achievement gaps affect marginalized students nation-wide. Environmental education (EE) does not currently nor historically represent a wide range of demographic backgrounds, and increasing concerns demonstrate the effects this can have on pedagogy of the field and the success of its students. Purpose: This research focuses on measures being reported by EE organizations in Wisconsin, and nearby regions, in their work to address diversity, equity, and inclusion (DEI) with consideration to inclusive practices, instructional materials, and overall pedagogy of EE. Methodology/Approach: In 2021, a web-based survey was emailed to 140 EE organization leaders and an updated version was emailed to 112 EE organization leaders in 2023. Responses were analyzed to determine the status of EE across the state and trends across years. Findings/Conclusions: The data does demonstrate a need for equity in EE, specifically supporting students with different learning needs or from underrepresented backgrounds. DEI initiative importance versus resources allocated is disjointed. Lack of consistent collection of demographic data leads EE organizations to fall short of DEI action. Implications: In order to better support learning and positive outcomes, it is significant that environmental educators reevaluate their practices to meet the needs of the growingly diverse students across the country.

Graphic materials have been prepared that describe the structure and logic of the module being developed. The technology stack used is presented, and the results of testing the updated version of the graphical shell using the example of one of the classic problems of continuum mechanics are presented. The results of the research were summed up, the tasks completed were noted, the expected practical value of the development and possible ways for further research in this direction were indicated, the repository with the source code of the graphical shell on the GitHub service was updated.

Accuracy and Reproducibility of Virtual Reality Perimetry in Children.

To determine normal threshold values for the 24-2 program of the VisuALL-K (Olleyes, Inc), a portable static automated virtual reality perimeter that uses a video game-based testing modality on an updated version of the algorithm and to repeat the test to assess retest variability. This prospective cohort study included 19 participants (aged 8 to 17 years) with healthy afferent systems. Participants performed two 24-2 automated perimetry tests on the virtual reality perimeter device. Mean age was 12.7 ± 2.5 years; 53% were boys and 47% were girls. Mean test location threshold was 30.5 ± 4.0 dB for test 1 and 31.3 ± 2.8 dB for test 2. Sensitivity decreased with eccentricity as expected (-0.17 dB per degree). Bland-Altman analysis showed a repeatability coefficient of ±5.1 dB for mean deviation, meaning that 95% of retest values were within ±5 dB of the threshold value for the first test. Higher thresholds for the first test regressed toward the mean values in the second test, indicating a learning effect. Intraclass correlation coefficient for mean deviation between test 1 and test 2 was 0.70 (0.55 to 0.80, P < .0001). Mean time to completion for the virtual reality perimeter was 5.1 ± 1.5 min/eye. The VisuALL-K virtual reality perimeter provided an assessment of the visual field in normal children aged 8 to 17 years. A shallow hill of vision was demonstrated. A notable learning effect was demonstrated, with repeatability difference wider than other published head-mounted display perimeters. [J Pediatr Ophthalmol Strabismus. 2024:61(4):262-266.].

The Promotion of Traditional Values through Films and Television Programmes: The Moscow Patriarchate and the Orthodox Encyclopaedia Project (2005–2022)

On 26 May 2011, the Russian People’s World Council issued a document entitled The Basic Values: The Fundaments of National Unity. The document, prepared by the Synodal Department for Church–Society Cooperation, provided a catalogue of 17 traditional values whose general framework was constituted by a combination of freedom, unity, patriotism, family, and devotion. At that time, the Moscow Patriarchate considered religious faith to be the foundation of traditional values and it continues to do so. The defence and promotion of traditional Russian spiritual and moral values were also central in the Russian National Security Strategy (2015); this was the case in the updated version of this document as well, put out in July 2021. Furthermore, they have been the core of the Moscow Patriarchate’s participation in the Council of Europe and of Patriarch Kirill’s speeches about the war in Ukraine. Finally, on 9 November 2022, The Foundations Of State Policy For The Preservation Of Spiritual And Moral Values was approved. This framework permits us to understand the strict interplay between the Church and the State in the Russian Federation and to see why it is important to refer to the concept of post-secularism when talking about the role of religion in post-Soviet Russia. Proceeding from the Abstract, the present paper aims to analyse this interplay in a specific sector of visual culture: the cinema and television industries. Manuel Castells highlighted the relevance of cultural values in the age of information and the connection between the values and social mobilization that follows it. He pointed out that the Internet has become a way to render this connection predominant, inevitably leading to the development of social movements and networks that have a religious basis. This is unquestionably true; surveys conducted by the Russian Public Opinion Research Center (OJSC «VCIOM») and by Nevafilm Research confirm that a high percentage of Russians watch films not only at the cinema or on television (especially the older generations) but also on the Internet (as far as the younger generations are concerned). The importance of this market is also confirmed by the success of the cinema and TV distributor Orthodox Encyclopaedia (2005); in the words of the philosopher Sergei Kravets, who, commenting on it during an interview published in 2006 by the website Sedmits.ru, declared that the expression “orthodox cinema” can be understood as a way to express Russian culture. He asserts that “the fact that today Orthodox films have begun to appear on the central TV channels testifies that Russian film producers and viewers have apparently begun to be aware of themselves as Orthodox, to feel that they are bearers of a special Orthodox culture. [..]”. At the same time, consideration should be given to the importance of the Russian Orthodox Church and the Minister of Culture’s condemnation of films such as Matilda or Monastery. In addition, it is important to consider that, according to a survey conducted in 2022 by the Levada Center, Russian people consider television the most reliable source of information (54%). The long-term implications of this tendency may have very important effects, not only in terms of its objectives but also in terms of the consideration that, after the beginning of the war, many Western film distributors withdrew their licenses from Russia. This paper will analyse “the effect of religion on the institutional system, the regulatory environment of the media and the public sphere” by studying the features of films and TV programs distributed by Orthodox Encyclopaedia, their relations with traditional values promoted both by the Kremlin and the Church, how these have contributed to strengthening the interplay between the Minister of Culture and the Moscow Patriarchate, and the impact this process has had on Russian society and Russia’s relations with the European and Western World in the 2005–2022 period. A list of the films and TV programs being discussed will be provided, and then statements about the project and reviews of the serials and films will be analysed. The analysis will be conducted mainly through the official sites of the Russian Orthodox Church and the Kremlin and by browsing the Integrum database.

Practical Aspects for Applying Picard Iterations to the SIR Model Using Actual Data

The updated version of the Picard method for solving systems of differential equations is employed to solve the SIR system. A local performance of the Picard iteration algorithm combined with the Gauss-Seidel approach is applied to the SIR model. The integral form of the SIR model, in addition to the use of Gauss-Seidel philosophy (using the most recent calculated values), achieved more accuracy in the computational work than those obtained using the differential forms. Documented data regarding the spread of corona virus 19 in the Kingdom of Saudi Arabia region from April to the end of December 2020 were used to calculate the corresponding actual values for the parameters and the initial conditions. Due to efficient management and to obtain representable behaviours, we restricted the size of the study to only 1% of the population. The global characteristics of the integral formulation have affected the calculations accurately. The initial conditions and the model’s parameters are established depending on the documented data. The results illustrate the superiority of the updated Picard formulation over the classical Picard within their domain of convergence. The results of this study illuminate and validate the importance of mathematical modeling. These findings can provide valuable insights into mathematical modeling for those involved in environmental health research, especially those responsible for devising strategic plans.

Numerical-model-derived intensity–duration thresholds for early warning of rainfall-induced debris flows in a Himalayan catchment

Abstract. Debris flows triggered by rainfall are catastrophic geohazards that occur compounded during extreme events. Few early warning systems for shallow landslides and debris flows at the territorial scale use thresholds of rainfall intensity–duration (ID). ID thresholds are mostly defined using hourly rainfall. Due to instrumental and operational challenges, current early warning systems have difficulty forecasting sub-daily time series of weather for landslides in the Himalayas. Here, we present a framework that employs a spatio-temporal numerical model preceded by the Weather Research And Forecast (WRF) Model for analysing debris flows induced by rainfall. The WRF model runs at 1.8 km × 1.8 km resolution to produce hourly rainfall. The hourly rainfall is then used as an input boundary condition in the spatio-temporal numerical model for debris flows. The debris flow model is an updated version of Van Asch et al. (2014) in which sensitivity to volumetric water content, moisture-content-dependent hydraulic conductivity, and seepage routines are introduced within the governing equations. The spatio-temporal numerical model of debris flows is first calibrated for the mass movements in the Kedarnath catchment that occurred during the 2013 North India floods. Various precipitation intensities based on the glossary of the India Meteorological Department (IMD) are set, and parametric numerical simulations are run identifying ID thresholds of debris flows. Our findings suggest that the WRF model combined with the debris flow numerical model shall be used to establish ID thresholds in territorial landslide early warning systems (Te-LEWSs).
