AbstractSandstone channels are one of the best stratigraphic traps for hydrocarbon accumulation, and their depositional and composition make them difficult to detect on ordinary seismic data, especially in structurally affected onshore areas like the Western Desert of Egypt. The Western Desert of Egypt has many hydrocarbon-bearing reservoirs of various compositions like carbonates and sandstones with high production rates, and thus the Western Desert of Egypt is recognized as a hot spot for oil and gas exploration. One of the important reservoirs in the Lower Cretaceous “the Aptian sand” produced around 285 MBBLS cumulative oil of 22° API and still produces 102 BOPD. This reservoir has a channel-type depositional environment, and the dimensions of this channel could be resolved by good quality 3D seismic data in the moderately deep basins as the basins become deeper, the detection of the channel becomes increasingly challenging. This study aims to delineate the geometry of this reservoir and reveal the exposure from the Aptian sand channel in the Alamein area using the seismic attributes analogy on the re-processed 3D seismic data to determine the best drilling location for increasing the production from this reservoir. In this context, the relative acoustic impedance (RAI), iso-frequency components, and sweetness stratigraphic attribute analyses were conducted on the optimized seismic data and attested as important as they resolved the stratigraphic geological mystery in the structurally affected study area. These attribute analyses revealed the exposure from the distinctive meander channel of the Aptian sand for the first time in the study area nearby the producing Alamein field, where this channel was hard to be distinguished by the ordinary seismic interpretation methods and there is no drilled well penetrated the detected channel’s body. Upon the results, the conclusion and recommendation summaries to intensify the efforts to test the productivity of the detected channel to increase the production from this motivating reservoir by drilling a new well targeting the best structural locations of the channel body.

Authors: Lagacé M , Michoulas A , Demos M , Connolly M 
Published: June 2022

Background: Seizures in childhood absence epilepsy (CAE) are typically easily controlled with anti-seizure medications (ASMs). Factors predictive of treatment resistance remain unclear. Our objectives were to assess prevalence of neuropsychiatric problems and factors influencing treatment resistance in a cohort of CAE at a single centre. Methods: We retrospectively reviewed patients with CAE diagnosed between January 1999 and December 2016 with at least 1-year follow-up. Treatment resistance was defined as failure to respond to two appropriate ASMs. Exclusion criteria included eyelid myoclonia with absence, myoclonic absence, and generalized tonic-clonic (GTC) seizures prior to absence seizures. Results: The study population comprised 164 patients (65 males) with mean age at seizures onset of 6.1years. 21% had treatment-resistant seizures. The first ASM was Ethosuximide (63.4%), Valproic acid (23.2%), and Lamotrigine (6.7%). 32.9% of children had learning disabilities, 28.7% ADHD, and 12.8 % anxiety.A stepwise binary logistic regression analysis identified GTC seizures, learning disability (LD) and ongoing general spike and wave on EEG as predictors of treatment resistance. At last follow-up (average of 5.4 years), 43.3% of children were seizure-free off ASMs. Conclusions: 21% of children with CAE had treatment-resistant seizures. LD, GTC and failure of normalization of the EEG were associated with treatment resistance.
Textual, Material, Visual: Exploring an Epigraphic Approach to the History of Imperial China
Authors: Wang Jinping 
Published: June 2022

AbstractIn this article, I advance a recent epigraphic approach to historical study by foregrounding steles as a medium that functions both to communicate information and project authority publicly. Scholars taking this approach have explored distinctive genres of steles to transform our understanding of north China under Mongol rule. Through a case study, I show how a set of steles installed in the fifteenth-century rural world of north China transmitted authority and power not just through the content of their inscriptions but also through other written and unwritten information they stored. I give particular attention to the ways in which the inscriptions were materialized and visualized. In doing so, I argue that emphasizing the public communication function of steles challenges us to think beyond primary sources strictly in terms of their textual value to reflect more broadly on modes of transmission and the power dynamics contained within them.

AbstractThe future contributions of the Antarctic Ice Sheet to sea level rise will depend on the evolution of its surface mass balance (SMB), which could amplify/dampen mass losses increasingly observed at the ice sheet's edge. In situ constraints of SMB over annual-to-decadal timescales consist mostly of firn/ice cores that have a surface footprint $\sim$cm$^{2}$. SMB constraints also come from climate models, which have a higher temporal resolution but a larger surface footprint of several km$^{2}$. We use ice-penetrating radar data to obtain an intermediate spatial and temporal resolution SMB record over three ice rises along the Princess Ragnhild Coast. The co-located ice cores allow us to obtain absolute radar-derived SMB rates at a multi-annual-to-decadal temporal resolution. By comparing the ice core SMB measurements and the radar-derived SMB records, we determine that pointwise measurements of SMB are representative of a small surface area, $\sim 200-500$ m radius extending from the ice core drill site for the ice rises studied here, and that the pointwise measurements are systematically 7–15 cm w.e. a$^{-1}$ lower than the mean SMB value calculated for the whole ice rises. However, ice core records are representative of an entire ice rise's temporal variability at the temporal resolution examined.
Ruin probabilities with investments: smoothness, inegro-differential and ordinary differential equations, asymptotic behavior
Authors: Kabanov Yuri , Pukhlyakov Nikita 
Published: June 2022

AbstractThis study deals with the ruin problem when an insurance company having two business branches, life insurance and non-life insurance, invests its reserves in a risky asset with the price dynamics given by a geometric Brownian motion. We prove a result on the smoothness of the ruin probability as a function of the initial capital, and obtain for it an integro-differential equation understood in the classical sense. For the case of exponentially distributed jumps we show that the survival (as well as the ruin) probability is a solution of an ordinary differential equation of the fourth order. Asymptotic analysis of the latter leads to the conclusion that the ruin probability decays to zero in the same way as in the already studied cases of models with one-sided jumps.
Concilier les approches sociohistoriques et les approches ethnographiques dans l’étude du nationalisme : une analyse de cas de la résonnance de la bataille des Éperons d'or en Flandre
Authors: Poitras Dave , Dufour Frédérick Guillaume 
Published: June 2022

RésuméCet article a pour point de départ la querelle épistémologique survenue entre Anthony D. Smith et Jon E. Fox et Cynthia Miller-Idriss concernant les différentes approches du champ d’études du nationalisme. Alors que Fox et Miller-Idriss rejettent la pertinence d'une approche sociohistorique dans l’étude ethnographique du nationalisme, Smith considère l'ethnographie comme une pratique descriptiviste dénuée d'intérêt scientifique qui, de surcroit, fait abstraction des recherches sur la nation conduite au cours des dernières décennies. Afin de dénouer cette impasse, nous proposons une démarche méthodologique visant à concilier ces deux approches par l'entremise du concept de lieu de mémoire. À partir d'une étude de cas, la bataille des Éperons d'or et sa résonance dans les pratiques discursives, nous illustrons comment l'historicité du fait national peut s'avérer essentielle pour comprendre le fonctionnement de la nation au quotidien et nous éclairer sur la manière dont les Flamands se construisent en tant que sujets nationaux.
Mobile robots path planning and mobile multirobots control: A review
Authors: Hichri Bassem , Gallala Abir , Giovannini Francesco , Kedziora Slawomir 
Published: June 2022

AbstractMobile robots and multimobile robotic system usage for task achievement have been an emerging research area since the last decades. This article presents a review about mobile robot navigation problem and multimobile robotic systems control. The main focus is made on path planning strategies and algorithms in static and dynamic environments. A classification on mobile robots path planning has been defined in the literature and divided to classical and heuristic approaches. Each of them has its own advantages and drawbacks. On the other hand, the control of multimobile robots is presented and the control approaches for a fleet of robots are presented. Scientists found that using more than one robot as opposed to a single one presents many advantages when considering redundant task, dangerous tasks, or a task that scales up or down in time or that requires flexibility. They have defined three main approaches of multiple robots control: behavior-based approach, leader–follower approach, and virtual structure approach. This article addresses these approaches and provides examples from the literature.
Passive with control and raising in mainland Scandinavian
Authors: Engdahl Elisabet 
Published: June 2022

AbstractThis article gives an overview of the use of non-local passives in mainland Scandinavian, i.e. passives where the subject of the first verb is a thematic argument of a second verb. Three factors are important: whether V1 is a control verb or a raising passive, whether V2 is a passive participle or an infinitive and whether the passive is morphological or periphrastic. Danish and Norwegian allow passive control verbs such as forsøge ‘try’ with passive participles whereas this pattern is only found with semi-control verbs like begära ‘request’ in Swedish. In Swedish there is an alternative strategy for strict control verbs, viz. active control verb plus passive infinitive. All three languages allow both passive infinitival complements and passive participles with raising passives such as påstås ‘is claimed’. These passive constructions need to be distinguished from so called long passives and double passives where a passive feature on either V1 or V2 can spread to the adjacent verb.
Carbon Border Measures, Environmental Effectiveness and WTO Law Compatibility: Is There a Way Forward for the Steel and Aluminium Climate Club?
Authors: Leonelli Giulia Claudia 
Published: June 2022

AbstractWith its narrow focus on price-based policies and ‘explicit’ carbon prices, the EU carbon border adjustment mechanism (CBAM) aims to prevent carbon leakage by ensuring that imported products ‘bear’ the same exact economic costs ‘borne’ by EU products. The proposed US border carbon adjustment (BCA) and the recent proposal for a global steel and aluminium arrangement (GSAA), by contrast, reflect a broader focus on environmental equivalence and recourse to punitive or quasi-punitive remedies. All recently proposed carbon border measures suffer from specific limitations. Further, albeit to a different extent, they are all associated with problematic aspects in terms of WTO law compatibility. This research note enquires whether the GSAA could be fine-tuned at the regulatory design stage in such a way as to provide an environmentally effective and WTO law compatible way forward. The analysis illustrates that recourse to an installation-based approach, emission limit values and product standards would achieve these goals. Nonetheless, the implementation of this ambitious strategy would be fraught with political obstacles.

Published: June 2022

AbstractThis case note critically analyses the logic of M/VEnrica Lexieof 2020 with a particular focus on the issue of the immunityratione materiae. This judgment is important in terms of the development of the principle of sovereign immunity. It first reviews the background of the case and the judgment. It then examines (1) the basis of the principle of sovereign immunity and (2) the territorial exception and its relevance to the law of the sea. It criticizes the logic of the judgment, particularly on its reference to the United Nations Convention on Jurisdictional Immunities of States and Their Property, regardless of the fact that the instrument only applies to civil proceedings. Finally, it comments on the Award's implication for anti-piracy international cooperation.

Published: June 2022

AbstractSince the late 1970s, successive satellite missions have been monitoring the sun's activity and recording the total solar irradiance (TSI). Some of these measurements have lasted for more than a decade. In order to obtain a seamless record whose duration exceeds that of the individual instruments, the time series have to be merged. Climate models can be better validated using such long TSI time series which can also help to provide stronger constraints on past climate reconstructions (e.g., back to the Maunder minimum). We propose a 3‐step method based on data fusion, including a stochastic noise model to take into account short and long‐term correlations. Compared with previous products scaled at the nominal TSI value of ∼1361 W/m2, the difference is below 0.2 W/m2 in terms of solar minima. Next, we model the frequency spectrum of this 41‐year TSI composite time series with a Generalized Gauss‐Markov model to help describe an observed flattening at high frequencies. It allows us to fit a linear trend into these TSI time series by joint inversion with the stochastic noise model via a maximum‐likelihood estimator. Our results show that the amplitude of such trend is ∼−0.004 ± 0.004 W/(m2yr) for the period 1980–2021. These results are compared with the difference of irradiance values estimated from two consecutive solar minima. We conclude that the trend in these composite time series is mostly an artifact due to the colored noise.

Published: June 2022

AbstractOcean‐atmosphere dynamics in the north Pacific play an important role in the global climate system and influence hydroclimate in western North America. However, changes to this region's mean climate under increased atmospheric greenhouse gas concentrations are not well understood. Here we present new alkenone‐based records of sea surface temperature (SST) from the northeast Pacific from the mid‐Piacenzian warm period (approximately 3.3–3.0 Ma), an interval considered to be an analog for near‐future climate under middle‐of‐the‐road anthropogenic emissions. We compare these and other alkenone‐based SST records from the north Pacific to fully‐coupled climate model simulations to examine the impact of mid‐Pliocene CO2 and other boundary conditions on regional climate dynamics and to explore factors governing model disagreement about regional temperature patterns. Model performance varies regionally, with Community Earth System Model 1.2 (CESM 1.2) and CESM2 performing best in regions with greater warming like the California Margin, though these models underestimate the warming evidenced in our new proxy record and others from the region. Single forcing simulations reveal a strong influence for prescribed land surface changes and higher CO2 levels on coastal warming patterns along the California Margin in CESM2. Furthermore, differences in shortwave and longwave radiation and circulation between the models, likely related to changes in the atmospheric component of the model, may play a key role in the ability of models to capture regionally‐varying patterns of Pliocene warmth. Regional patterns of temperature change inferred from geochemical records could therefore help to understand the impacts of different model parameterization schemes on regional climate patterns.
Lagrangian Analysis of Moisture Sources of Precipitation in the Tianshan Mountains, Central Asia
Authors: Guan Xuefeng , Langhamer Lukas , Schneider Christoph 
Published: June 2022

AbstractThe moisture sources of precipitation in the Tianshan Mountains, one of the regions with the highest precipitation in Central Asia during 1979–2017 are comprehensively and quantitatively summarized by using a Lagrangian moisture source detection technique. Continental sources provide about 93.2% of the moisture for precipitation in the Tianshan Mountain, while moisture directly from the ocean is very limited, averaging only 6.8%. Central Asia plays a dominant role in providing moisture for all sub‐regions of the Tianshan Mountains. For the Western Tianshan, moisture from April to October comes mainly from Central Asia (41.4%), while moisture from November to March is derived primarily from Western Asia (45.7%). Nearly 13.0% of moisture to precipitation for Eastern Tianshan in summer originates from East and South Asia, and the Siberia region. There is a significant decreasing trend in the moisture contribution of local evaporation and Central Asia in the Eastern Tianshan during winter. The contribution of moisture from Europe to summer precipitation in the Central and Eastern Tianshan and the contribution of the North Atlantic Ocean to summer precipitation in the Northern, Central, and Eastern Tianshan also exhibit a decreasing trend. The largest increase in moisture in Western Tianshan stems from West Asia during extreme winter precipitation months. Europe is also an important contributor to extreme precipitation in the Northern Tianshan. The moisture from East and South Asia and Siberia during extreme precipitation months in both winter and summer is significantly enhanced in the Eastern Tianshan.

AbstractThe electrical penetration of the cell membrane is vital for determining the cell interior via impedance cytometry. Herein, we propose a method for determining the conductivity of the cell membrane through the tilting levels of impedance pulses. When electrical penetration occurs, a high-frequency current freely passes through the cell membrane; thus, the intracellular distribution can directly act on the high-frequency impedance pulses. Numerical simulation shows that an uneven intracellular component distribution can affect the tilting levels of impedance pulses, and the tilting levels start increasing when the cell membrane is electrically penetrated. Experimental evidence shows that higher detection frequencies (>7 MHz) lead to a wider distribution of the tilting levels of impedance pulses when measuring cell populations with four-frequency impedance cytometry. This finding allows us to determine that a detection frequency of 7 MHz is able to pass through the membrane of Euglena gracilis (E. gracilis) cells. Additionally, we provide a possible application of four-frequency impedance cytometry in the biomass monitoring of single E. gracilis cells. High-frequency impedance (≥7 MHz) can be applied to monitor these biomass changes, and low-frequency impedance (<7 MHz) can be applied to track the corresponding biovolume changes. Overall, this work demonstrates an easy determination method for the electrical penetration of the cell membrane, and the proposed platform is applicable for the multiparameter assessment of the cell state during cultivation.

AbstractPigs are valuable large animal models for biomedical and genetic research, but insights into the tissue- and cell-type-specific transcriptome and heterogeneity remain limited. By leveraging single-cell RNA sequencing, we generate a multiple-organ single-cell transcriptomic map containing over 200,000 pig cells from 20 tissues/organs. We comprehensively characterize the heterogeneity of cells in tissues and identify 234 cell clusters, representing 58 major cell types. In-depth integrative analysis of endothelial cells reveals a high degree of heterogeneity. We identify several functionally distinct endothelial cell phenotypes, including an endothelial to mesenchymal transition subtype in adipose tissues. Intercellular communication analysis predicts tissue- and cell type-specific crosstalk between endothelial cells and other cell types through the VEGF, PDGF, TGF-β, and BMP pathways. Regulon analysis of single-cell transcriptome of microglia in pig and 12 other species further identifies MEF2C as an evolutionally conserved regulon in the microglia. Our work describes the landscape of single-cell transcriptomes within diverse pig organs and identifies the heterogeneity of endothelial cells and evolutionally conserved regulon in microglia.
