Reduced-order digital twin and latent data assimilation for global wildfire prediction
Authors: Zhong Caili , Cheng Sibo , Kasoar Matthew , Arcucci Rossella
Published: May 2023

Abstract. The occurrence of forest fires can impact vegetation in
the ecosystem, property, and human health but also indirectly affect the
climate. The Joint UK Land Environment Simulator – INteractive Fire and Emissions
algorithm for Natural envirOnments (JULES-INFERNO) is a global land surface model, which simulates
vegetation, soils, and fire occurrence driven by environmental factors.
However, this model incurs substantial computational costs due to the high
data dimensionality and the complexity of differential equations. Deep-learning-based digital twins have an advantage in handling large amounts of
data. They can reduce the computational cost of subsequent predictive models
by extracting data features through reduced-order modelling (ROM) and then
compressing the data to a low-dimensional latent space. This study proposes
a JULES-INFERNO-based digital twin fire model using ROM techniques and deep
learning prediction networks to improve the efficiency of global wildfire
predictions. The iterative prediction implemented in the proposed model can
use current-year data to predict fires in subsequent years. To avoid the
accumulation of errors from the iterative prediction, latent data
assimilation (LA) is applied to the prediction process. LA manages to
efficiently adjust the prediction results to ensure the stability and
sustainability of the prediction. Numerical results show that the proposed
model can effectively encode the original data and achieve accurate
surrogate predictions. Furthermore, the application of LA can also
effectively adjust the bias of the prediction results. The proposed digital
twin also runs 500 times faster for online predictions than the original
JULES-INFERNO model without requiring high-performance computing (HPC)
clusters.

Published: May 2023

Abstract. The ability to understand and predict coarse-sediment transport in torrent catchments is a key element for the protection against and prevention of the associated hazards. In this study, we collected data describing sediment supply at 99 torrential catchments in the northern French Alps. The sample covers a wide range of geomorphic activity: from torrents experiencing debris flows every few years to fully forested catchments exporting small bed load volumes every decade. These catchments have long records of past events and sediment supply to debris basins. The mean annual, the 10-year return period and the reference volume (i.e., the 100-year return level or the largest observed volume) of sediment supply were derived for the studied torrents. We examined the relationships between specific sediment supply volumes and many explanatory variables using linear regression and random forest approaches. Results showed that the ratio of sediment-contributing area (bare soil or rock) to catchment area is the most important predictor of the specific sediment production volumes (m3 km−2). Other variables such as the Melton index or the indices of sediment connectivity also have an influence. Several predictive models were developed in order to estimate the sediment supply in torrents that are not equipped with debris basins.

Abstract. Snow is a critical water resource for the western United States and many regions across the globe. However, our ability to accurately measure and monitor changes in snow mass from satellite remote sensing, specifically its water equivalent, remains a challenge. To confront these challenges, NASA initiated the SnowEx program, a multiyear effort to address knowledge gaps in snow remote sensing. During SnowEx 2020, the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) team acquired an L-band interferometric synthetic aperture radar (InSAR) data time series to evaluate the capabilities and limitations of repeat-pass L-band InSAR for tracking changes in snow water equivalent (SWE). The goal was to develop a more comprehensive understanding of where and when L-band InSAR can provide SWE change estimates, allowing the snow community to leverage the upcoming NASA–ISRO (NASA–Indian Space Research Organization) SAR (NISAR) mission. Our study analyzed three InSAR image pairs from the Jemez Mountains, NM, between 12 and 26 February 2020. We developed a snow-focused multi-sensor method that uses UAVSAR InSAR data synergistically with optical fractional snow-covered area (fSCA) information. Combining these two remote sensing datasets allows for atmospheric correction and delineation of snow-covered pixels within the radar swath. For all InSAR pairs, we converted phase change values to SWE change estimates between the three acquisition dates. We then evaluated InSAR-derived retrievals using a combination of fSCA, snow pits, meteorological station data, in situ snow depth sensors, and ground-penetrating radar (GPR). The results of this study show that repeat-pass L-band InSAR is effective for estimating both snow accumulation and ablation with the proper measurement timing, reference phase, and snowpack conditions.
What distinguishes 100-year precipitation extremes over central European river catchments from more moderate extreme events?
Authors: Ruff Florian , Pfahl Stephan
Published: May 2023

Abstract. Historical extreme flooding events in central European river catchments caused high socioeconomic impacts. Previous studies have analysed single events
in detail but have not focused on a robust analysis of the underlying extreme precipitation events in general, as historical events are too rare for a
robust assessment of their generic dynamical causes. This study tries to fill this gap by analysing a set of realistic daily 100-year large-scale
precipitation events over five major European river catchments with the help of operational ensemble prediction data from the ECMWF. The dynamical
conditions during such extreme events are investigated and compared to those of more moderate extreme events (20 to 50 year); 100-year precipitation
events are generally associated with an upper-level cutoff low over central Europe in combination with a surface cyclone southeast of the specific
river catchment. The 24 h before the event is decisive for the exact location of this surface cyclone, depending on the location and
velocity of the upper-level low over western Europe. The difference between 100-year and more moderate extreme events varies from catchment to
catchment. Dynamical mechanisms such as an intensified upper-level cutoff low and surface cyclone are the main drivers distinguishing 100-year
events in the Oder and Danube catchments, whereas thermodynamic mechanisms such as a higher moisture supply in the lower troposphere east of the
specific river catchment are more relevant in the Elbe and Rhine catchments. For the Weser and Ems catchment, differences appear in both dynamical and
thermodynamic mechanisms.

Published: May 2023

Re-engineer clinical teaching through innovative approaches such as virtual reality (VR) and Serious Gaming (SG) may increase patient safety. While several studies have focused on the experiences and perceptions of learners about VR and SG, few have if any have focused on the instructors. We reviewed and appraised published evidence to establish the experiences and intention to adopt VR and SG in clinical teaching. Relevant articles were sourced from five databases (PubMed/Medline, Informit, +A Education, ProQuest-ERIC, and CINHAL-EBSCO host). Experiences of clinical trainers were reported using the technological, pedagogical, and content knowledge (TPACK) model. The intention to adopt VR and SG was synthesized using the Technology Adoption Model (TAM). Clinical trainers had a positive attitude towards VR and SG. Those with longer professional experience were less likely to adopt VR and SG, while more experienced trainers were more likely to benefit from VR and SG. VR and SG are practical pedagogies for clinical instruction, but training is required for novice users. Cost-benefit analysis of VR and SG as clinical training approaches is needed.
Reproducibility of Statistical Hypothesis Tests
Authors: Coolen Frank
Published: May 2023

Reproducibility is of great importance for scientific research. While many practical issues affecting reproducibility have received much attention in recent years, the reproducibility of statistical inferences has received rather little attention. This talk presents an overview of our recent development of methods to quantify reproducibility of statistical hypothesis tests using nonparametric predictive inference (NPI). Reproducibility is considered to be a predictive problem, with emphasis on the probability that a repeat of a test will lead to the same conclusion as an actual test. After introducing the basics of NPI, its application to reproducibility of basic tests is illustrated for small sample sizes. For larger sample sizes, or more complicated tests, approximate methods for computation are presented.

Published: May 2023

The characteristics of an anisotropic medium over hydrocarbons are studied using phase methods based
on amplitude-modulated signals. Experimental studies of the phase characteristics of the surface impedance in the
mode of amplitude-modulated signals have been carried out. Two components of the surface impedance are analyzed
for this mode. A study was made of the influence of probing signal modes on the characteristics of an anisotropic
medium over deposits based on a two-channel measurement scheme. A method for registering the boundaries
of hydrocarbon deposits is proposed, based on the use of phase methods for searching and identifying
hydrocarbon deposits (HCW) in the mode of amplitude-modulated signals. The research results can be used
in the development of radio engineering systems for searching and delineating oil and gas deposits and their
application for exploration geophysics.

Giorgio Agamben’in giriştiği ekonomi politiğin jenealojisi ve yeminin arkeolojisi bağlamında kutsallığın dilinin batı felsefesinde yarattığı muallak alakaya bakmak vesilesiyle, Homo Sacer’in ilk cildinde egemenliğin paradoksu olarak karşımıza çıkan istisna hâlinin nasıl da ilahiyatçı bir selamet ekonomisinden kaynaklandığını fark ederiz. Böyle bir selamet ekonomisi idare etmenin malik olmayı sağladığı litürjik ve doksolojik gelenek hattında kurulurken, bu selamet ekonomisini yürürlüğe koyan, dilin sembolik olarak fiilileşmesidir. İstisnai olarak yürürlükte olan bu sembolik ekonominin dilinin ontolojiyi (fiilî olanın hükmüyle iradi buyruk formunda — varoluş pahasına —) ödev ahlakına tabi kıldığını gösteren Agamben’in (yine bu dilin içinde) varlığı başka türlü istimal eden bir hayat formunun misalini verdiğine tanıklık edildiğinde ise, bunun bizatihi dilin imkânı olarak aynı ekonomi politiğin bir sui-istimalini sağladığını söyleyebilme fırsatı doğar.

Descartes’ın rüya şüpheciliği, uyku ve uyanıklık halinin nasıl ayırt edileceği üzerine gelişmiştir. Descartes, ‘Şu an rüyada olmadığımı nereden bilebilirim?’ sorusu ile rüyayı, epistemik şüphesinin merkezine oturtmaktadır. Descartes sonrası Kartezyen rüya şüpheciliğini de belirleyen bu problem, epistemik şüpheden ontolojik şüpheye de evrilmiş ve rüya konusu hem epistemolojinin hem ontolojinin konusu haline gelmiştir. Bu aşamada odaklanılan husus, “Rüyalarımızın bilinçli deneyimler midir?” sorusudur.

Bu makale Descartes'ın rüya şüpheciliğinden daha ziyade, "Rüyalarımız bilinçli deneyimler midir?" sorusu çerçevesinde çağdaş filozoflar Malcolm ve Dennett'in Kartezyen rüya şüpheciliğine yönelik eleştirilerine odaklanmaktadır. Rüyaların felsefi bir analizle nasıl çözüleceğinin örneklerini sunan bu iki filozofun, Kartezyen Rüya şüpheciliğine alternatif geliştirdikleri rüya anlayışı ele alınmıştır.

Bungus Bay Ferry Terminal is the only access for vehicles and passengers between Padang City and the Mentawai Islands Regency. Mentawai Islands Regency is a separate district from West Sumatra Province, which is located in the westernmost island of Sumatra and is surrounded by the waters of the Indian Ocean. There are 2 (two) Ro - Ro ships belonging to PT. ASDP Indonesia Ferry (Persero) Padang branch serving the Padang - Mentawai Islands route. The existence of this Ferry Port is very important in an effort to support economic development and progress in the Mentawai Islands. However, at this time the crossing port zoning system has not been implemented which causes the traffic flow pattern of passengers and vehicles at this port to not run well. It is necessary to implement a Ferry Port zoning system with zoning restrictions based on PM 29/2016 concerning the Sterilization of Ferry Ports and to apply regulations on traffic flow patterns for passengers and vehicles based on SK.242 / HK.104 / DRJD / 2010 concerning Technical Guidelines for Cross Traffic Management.

Sape Port is a port managed by PT. ASDP Indonesia Ferry (Persero) Sape Branch. At this time at the Sape Crossing Port there are still several shortcomings because there are still many people and unauthorized vehicles that can easily enter the port area, causing the port to become less orderly, there are still crossings between vehicles that will enter the ship and vehicles those who get out of the ship, and hawkers selling their goods in the area around the pier. This is due to the absence of a zoning system that is in accordance with the Minister of Transportation Regulation Number 29 of 2016 concerning the Sterilization of Ferry Ports. So that in the activity of getting on and off of passengers and loading and unloading vehicles, there are several obstacles, including the absence of zoning implementation at the port which causes unauthorized people to enter prohibited areas, and the mixing of passengers and vehicles when getting on or off the ship. To analyze this, refer to the Regulation of the Minister of Transportation Number 29 of 2016 concerning the Sterilization of Ferry Ports and SK.242 / HK.104 / DRJD / 2010 concerning Technical Guidelines for Ferry Traffic Management. The analysis used is zoning analysis, analysis of equipment that supports the zone system, and analysis of vehicle flow patterns. In order to smoothen the flow of cargo traffic both entering the port area and cargo going out of the Ferry Port area, namely by implementing a zoning system based on the Minister of Transportation Regulation Number 29 of 2016 concerning Ferry Port Sterilization and regulation of traffic flow patterns in accordance with SK.242 /HK.104/DRJD/2010 concerning Technical Guidelines for Pedestrian Traffic Management and adding equipment that supports the zone system such as signs needed to support safety and comfort. The desired pattern of vehicle movement is to rearrange the lanes of vehicles that leave and enter the ship so that the delivery / pick-up does not enter the prohibited area and assign officers to regulate traffic so that it runs more orderly. To regulate passenger movement patterns so as not to mix with vehicles that would endanger the safety of passengers and vehicles.
