Spatial spin-up of precipitation in limited-area convection-permitting simulations over North America using the CRCM6/GEM5.0 model
Authors: Roberge François , Di Luca Alejandro , Laprise René , Lucas-Picher Philippe , Thériault Julie
Published: February 2024

Abstract. A fundamental issue associated with the dynamical downscaling technique using limited-area models is related to the presence of a “spatial spin-up” belt close to the lateral boundaries where small-scale features are only partially developed. Here, we introduce a method to identify the distance from the border that is affected by the spatial spin-up (i.e., the spatial spin-up distance) of the precipitation field in convection-permitting model (CPM) simulations. Using a domain over eastern North America, this new method is applied to several simulations that differ on the nesting approach (single or double nesting) and the 3-D variables used to drive the CPM simulation. Our findings highlight three key points. Firstly, when using a single nesting approach, the spin-up distance from lateral boundaries can extend up to 300 km (around 120 CPM grid points), varying across seasons, boundaries and driving variables. Secondly, the greatest spin-up distances occur in winter at the western and southern boundaries, likely due to strong atmospheric inflow during these seasons. Thirdly, employing a double nesting approach with a comprehensive set of microphysical variables to drive CPM simulations offers clear advantages. The computational gains from reducing spatial spin-up outweigh the costs associated with the more demanding intermediate simulation of the double nesting. These results have practical implications for optimizing CPM simulation configurations, encompassing domain selection and driving strategies.

Published: February 2024

Abstract. Understanding the number and types of signatures that best describe streamflow time series is a crucial objective in hydrological science, serving applications such as catchment classification, hydrological model development and calibration. With the main objective of learning a minimal number of streamflow features, we employ an explicit noise conditional autoencoder (ENCA), which, together with meteorological forcings, allows for an accurate reconstruction of the whole streamflow time series. The ENCA architecture feeds the meteorological forcing to the decoder in order to incentivize the encoder to only learn features that are related to landscape properties. By isolating the effect of meteorology, these features can thus be interpreted as landscape fingerprints. The optimal number of features is found by means of an intrinsic dimension estimator. We train our model on the hydro-meteorologic time series data of 568 catchments of the continental United States from the CAMELS dataset. We compare the reconstruction accuracy with state-of-the-art models that take as input a subset of static catchment attributes (both climate and landscape attributes) along with the meteorological forcing variables. Our results suggest that available static catchment attributes compiled by experts account for almost all the relevant information about the rainfall-runoff relationship. Yet, these catchment attributes can be summarized by only two relevant learnt features (or signatures), while a third one is needed for about a dozen difficult catchments in the central US, mainly characterized by high aridity index and intermittent flow. The principal components of the learnt features strongly correlate with the baseflow index and aridity indicators, which is consistent with the idea that these indicators capture the variability of catchment hydrological response and relate to needed model complexity. The correlation analysis further indicates that soil-related and vegetation attributes are of high importance. Finally, in the attempt to interpret the learnt catchment features, we relate them to typical hydrological model components, with specific reference to the parameters of the GR4J model and their function on the hydrograph.
Bayesian physical–statistical retrieval of snow water equivalent and snow depth from X- and Ku-band synthetic aperture radar – demonstration using airborne SnowSAr in SnowEx'17
Authors: Singh Siddharth , Durand Michael , Kim Edward , Barros Ana P.
Published: February 2024

Abstract. A physical–statistical framework to estimate snow water equivalent (SWE) and snow depth from synthetic aperture radar (SAR) measurements is presented and applied to four SnowSAR flight-line data sets collected during the SnowEx'2017 field campaign in Grand Mesa, Colorado, USA. The physical (radar) model is used to describe the relationship between snowpack conditions and volume backscatter. The statistical model is a Bayesian inference model that seeks to estimate the joint probability distribution of volume backscatter measurements, snow density and snow depth, and physical model parameters. Prior distributions are derived from multilayer snow hydrology predictions driven by downscaled numerical weather prediction (NWP) forecasts. To reduce the signal-to-noise ratio, SnowSAR measurements at 1 m resolution were upscaled by simple averaging to 30 and 90 m resolution. To reduce the number of physical parameters, the multilayer snowpack is transformed for Bayesian inference into an equivalent one- or two-layer snowpack with the same snow mass and volume backscatter. Successful retrievals meeting NASEM (2018) science requirements are defined by absolute convergence backscatter errors ≤1.2 dB and local SnowSAR incidence angles between 30 and 45∘ for X- and Ku-band VV-pol backscatter measurements and were achieved for 75 % to 87 % of all grassland pixels with SWE up to 0.7 m and snow depth up to 2 m. SWE retrievals compare well with snow pit observations, showing strong skill in deep snow with average absolute SWE residuals of 5 %–7 % (15 %–18 %) for the two-layer (one-layer) retrieval algorithm. Furthermore, the spatial distributions of snow depth retrievals vis-à-vis lidar estimates have Bhattacharya coefficients above 94 % (90 %) for homogeneous grassland pixels at 30 m (90 m resolution), and values up to 76 % in mixed forest and grassland areas, indicating that the retrievals closely capture snowpack spatial variability. Because NWP forecasts are available everywhere, the proposed approach could be applied to SWE and snow depth retrievals from a dedicated global snow mission.

Published: February 2024

Abstract. Ice sheet mass loss from Antarctica is greatest in the Amundsen Sea sector, where “warm” modified Circumpolar Deep Water moves onto the continental shelf and melts and thins the bases of ice shelves hundreds of meters below the sea surface. We use nearly 1000 paired salinity and oxygen isotope analyses of seawater samples collected on seven expeditions from 1994 to 2020 to produce a time series of glacial meltwater inventory for the southeastern Amundsen Sea continental shelf. Deep water column salinity–δ18O relationships yield freshwater end-member δ18O values from -31.3±1.0‰ to -28.4±1.0‰, consistent with the isotopic composition of local glacial ice. We use a two-component meteoric water end-member approach that accounts for precipitation in the upper water column, and a pure glacial meteoric water end-member is employed for the deep water column. Meteoric water inventories are comprised of nearly pure glacial meltwater in deep shelf waters and of >74 % glacial meltwater in the upper water column. Total meteoric water inventories range from 8.1±0.7 to 9.6±0.8 m and exhibit greater interannual variability than trend over the study period, based on the available data. The relatively long residence time in the southeastern Amundsen Sea allows changes in mean meteoric water inventories to diagnose large changes in local melt rates, and improved understanding of regional circulation could produce well-constrained glacial meltwater fluxes. The two-component meteoric end-member technique improves the accuracy of the sea ice melt and meteoric fractions estimated from seawater δ18O measurements throughout the entire water column and increases the utility for the broader application of these estimates.

Published: February 2024

Abstract. In frozen cylinders composed of deuterium ice (Tm+3.8 ∘C) and 10 % water ice (Tm 0 ∘C), it is possible to track melt pathways produced by increasing the temperature during deformation. Raising the temperature to +2 ∘C produces water (H2O) which combines with the D2O ice to form mixtures of HDO. As a consequence of deformation, HDO and H2O meltwater are expelled along conjugate shear bands and as compactional melt segregations. Melt segregations are also associated with high-porosity networks related to the location of transient reaction fronts where the passage of melt-enriched fluids is controlled by the localized ductile yielding and lowering of the effective viscosity. Accompanying the softening, the meltwater also changes and weakens the crystallographic fabric development of the ice. Our observations suggest meltwater-enriched compaction and shear band initiation provide instabilities and the driving force for an enhancement of permeability in terrestrial ice sheets and glaciers.

Feria IV
Authors: Pescada Gonçalo
Published: February 2024

Feria IV, an original work written for accordion by Franco Donatoni, reflects the singularity of a composer who marked his time for his unique genius and creativity, innovating musical writing with deep influences from Webern, Boulez and Stockhausen. Based on the idea that the previously presented material could be reformulated in such a way that it would never run out, Donatoni developed a Bricolage concept in his music, directing rhythms, causing rapid changes in texture and reusing the materials from one piece to another. A frequent participant in Darmstad summer courses composition, his music is characterized by constant expressiveness, lyricism, enthusiasm and exaltation of spirit. The article is presented in three sections: general notions about the composer and work, interpretive analysis and the interpreter's point of view conclusions about Donatoni’s concept as a catalyst for the creative process.

Quality Control Analysis of Neomycin, Gramicidin and Triamcinolone in Ointment Formulation using HPLC Methodology: Methodology Development, Validation and Application
Authors: Pushpa M.S. Swarna , Rajeswari T. Raja
Published: February 2024

The combination of gramicidin (GMN), a bactericidal agent; neomycin (NMN), an aminoglycoside; and triamcinolone (TAA), a glucocorticoid, is used for treating eye infections that are accompanied by inflammation. The contents of GMN, NMN, and TAA in eye ointments must be monitored for quality. In this research, a quick, selective, and robust stability-indicating HPLC method has been developed for the concurrent assay of GMN, NMN, and TAA in bulk and ointment formulations. Analysis was performed using ODS, a250mm × 4.6mm column and mobile phase having 0.1% aqueous formic acid-acetonitrile with a ratio of 20:80 v/v; PDA analysis was performed at 225nm. The elution times for GMN, NMN, and TAA were 2.597min, 4.440min, and 3.251 min, respectively. The GMN, NMN, and TAA linear ranges were 0.625 µg/ml to 3.75 µg/ml, 6.25 µg/ml to 37.50µg/ml and 2.5µg/ml to 15.0µg/ml, respectively. The method is precise with 0.68-0.96% (GMN), 0.52-1.02% (NMN), and 0.26-0.62% (TAA) RSD values. The method is accurate with 98.75-101.25% (GMN), 98.61-100.33% (NMN), and 98.67-100.23% (TAA) recovery values. In degradation investigation, the degradant’s peak elution times are different from the elution times of GMN, NMN, and TAA. Thus, the proved specificity and stability indicating the power of the method. Finally, this developed analytical approach was efficaciously applied to a commercial ointment formulation containing afixed dose of GMN, NMN, and TAA, demonstrating its usefulness for quality control and degradation investigations on GMN, NMN, and TAA.

Authors: Bhattacharya Muniraj , Sarkar Oindreela , K. De Pintu
Published: February 2024

Fast dissolving oral film (FDOF) are drug delivery systems of the new days having one of the highest patient compliance, safety and are economical than most other dosage forms. Hydrophilic polymers when used as a vehicle come in contact with water get hydrated and thus allow drug release. Hydrophilic polymers also show an adherence property post hydration. Thus the hydrating and adhering properties of hydrophilic polymers makes it most suitable for producing fast dissolving oral film. Fast dissolving oral films are made to be administered into the buccal cavity of humans as the buccal cavity if having saliva and saliva help to hydrate the films leading to drug release. The buccal cavity in humans has a very high amount of blood supply system thus aids in faster drug entrance into the blood circulation. The fast dissolving oral films are capable of initiating drug release within seconds, without chewing and drinking. The instant bioavailability achieved bypassing the fast pass metabolism also adds as a salient feature. Various compositions of different polymers lead to differences in drug release rate of the films. Polymers such as Hydroxy Propyl Methyl Cellulose; Poly Vinyl Alcohol; Ethyl Cellulose; Sodium Carboxymethyl Cellulose are some common hydrophilic polymers that are used to produce fast dissolving oral films. Solvent casting; semi solid casting; hot melt extrusion; solid dispersion extrusion are some common methods of production of fast dissolving oral films. Immediate onset of action in a shorter period with improved bioavailability marked fast dissolving oral film, a dosage form of choice.

Authors: Nand Kumar Et al.
Published: February 2024

The reliability and robustness of communication networks are critical for ensuring seamless connectivity in today's interconnected world. However, network faults and failures can disrupt services, leading to significant downtime and financial losses. [1]In response to these challenges, self-healing networks empowered by artificial intelligence (AI) have emerged as a promising solution for proactively detecting and autonomously recovering from network faults. This paper presents a comprehensive review and analysis of AI-based approaches for fault detection and recovery in self-healing networks, aiming to enhance network reliability and minimize service disruptions. It provides an overview of the key challenges associated with traditional fault detection and recovery methods in communication networks.[2] It discusses the limitations of reactive approaches that rely on manual intervention or predefined rules to identify and mitigate network faults, highlighting the need for more proactive and adaptive solutions. Subsequently, the paper explores the role of artificial intelligence, particularly machine learning and deep learning techniques, in enabling self-healing capabilities in communication networks. By leveraging vast amounts of network data, AI algorithms can learn complex patterns and anomalies indicative of network faults, enabling timely detection and response. The paper reviews various AI-based fault detection techniques, including anomaly detection, supervised learning, and reinforcement learning approaches. It examines their strengths and limitations in different network environments, considering factors such as data availability, scalability, and real-time processing requirements. Furthermore, the integration of AI-based fault detection with network monitoring systems and telemetry data sources is discussed, highlighting the importance of comprehensive data-driven approaches for accurate fault identification. In addition to fault detection, the paper investigates AI-driven recovery mechanisms for self-healing networks. It explores proactive recovery strategies, such as predictive maintenance and network reconfiguration, enabled by AI-based predictive analytics. By harnessing the power of machine learning and deep learning, communication networks can achieve greater resilience, adaptability, and autonomy in mitigating network faults and ensuring uninterrupted service delivery.
‘Yo soy la única burra’ [I’m the only dumb one]. Not Anymore. An Intersectional Approach to Digital Inclusion
Authors: Silva Claudia , Mora Adolfo R. , Straubhaar Joseph D
Published: February 2024

This paper applies intersectionality theory to analyze the challenges and successes of vulnerable communities in developing techno-capital—a form of cultural capital that influences individuals’ technology adoption and usage. Through ethnographic methods, such as participant observations and interviews among a group of working-class US Latinas in central Texas, this work aims to explore why digital inclusion programs should go beyond the first and second levels of the digital divide. Our findings show that this group of women faced unique barriers to digital inclusion, such as skills, time, perceived self-exclusion, and self-doubt. Even when Internet access, devices, and knowledge existed in their homes, they felt they lacked the abilities to access them, thus reflecting complex gendered family dynamics. A two-year ethnography with a non-profit serving the youth and parents of their neighborhood revealed that even this organization had trouble recognizing multiple, interconnected issues arising from gender, household roles, and age on top of the other categories of issues faced by working-class Latino immigrants in a large urban enclave. However, intersectional analysis by the lead author, when working for the non-profit, enabled her to better see and make decisions to serve these women’s needs for digital inclusion and parent education.
Predicting cheating among married individuals based on sexual satisfaction and personality traits: A review
Authors: Somaye Robatmili  , Mahla Yazdani
Published: February 2024

This article discusses the prediction of cheating among married individuals based on two significant factors: sexual satisfaction and personality traits. Sexual satisfaction is an essential component of a healthy and fulfilling relationship, and individuals who experience a lack of fulfillment in their sexual lives may seek satisfaction outside their marriage. Personality traits play a crucial role in determining an individual's propensity for cheating, with several traits commonly associated with a higher likelihood of engaging in infidelity, including low levels of conscientiousness, high levels of impulsivity, narcissism, and a desire for novelty and excitement. While sexual satisfaction and personality traits each contribute to the prediction of cheating, their interaction can further enhance our understanding. Developing reliable predictive models for cheating based on sexual satisfaction and personality traits is a complex task, with researchers using various methods to discern patterns and make accurate predictions. Data analysis techniques, such as logistic regression and machine learning algorithms, have been applied to collected data on married individuals and their tendencies to cheat, achieving moderate success in predictive accuracy. However, it is essential to acknowledge the limitations of these predictions, such as individual circumstances, relationship dynamics, and other external variables that are not accounted for in these models. Privacy concerns and ethical considerations surrounding the monitoring of individuals' personal lives must also be taken into account. These predictive models should be used with caution and in conjunction with comprehensive counseling and support systems to maintain the integrity of relationships.
An evaluation of the federal Transition Incentives Program on land access for next-generation farmers
Authors: Horst Megan , Valliant Julia , Freedgood Julia
Published: February 2024

Next-generation farmers face immense challenges in securing land. In recent years, some state- and federal-level land access policy incentives (LAPIs) have been implemented to address these chal­lenges. In this paper, we assess the Transition Incentives Program (TIP), an initiative of the U.S. Department of Agriculture’s Conservation Reserve Program that is funded by Congressional farm bills. TIP offers landowners two years of financial incen­tives for leasing or selling to a beginning or socially disadvantaged farmer or rancher (categories of farmers defined by the U.S. Department of Agri­culture). In our study, we characterize TIP partici­pants to understand where and how TIP assists beginning and socially disadvantaged farmers and ranchers. Our findings demonstrate that TIP serves some landowners and next-generation farmers, primarily in the Midwest and Mountain West. We demonstrate a spatial mismatch between where next-generation farmers live and high rates of TIP participation. Variable participation may be due to inconsistent outreach and limits to the program design. We identify key barriers and provide insights to improve TIP and other land access programs for next-generation farmers.

O objetivo deste estudo foi avaliar o desempenho do método de descontaminação de Ogawa - Kudoh e a técnica de "swab"em meio de Ogawa (MOK), paralelamente à metodologia tradicional de Petroff em meio de Lowenstein - Jensen (MP) para o isolamento de micobactérias de espécimes clínicos de origem pulmonar e extrapulmonar. Foram analisadas 779 amostras de pacientes com suspeita clínica de tuberculose pulmonar e/ou micobacteriose. Destas, a positividade do MP foi de 13,96% e do MOK foi de 16,23% e a sensibilidade do MOK foi de 79% e a especificidade 94%. Observou-se ainda o crescimento das culturas mais rápido pelo MOK e uma menor contaminação. Pelos resultados obtidos, associados à simplicidade e baixo custo do método, o mesmo apresentou condições favoráveis de implantação na rotina laboratorial dos Laboratórios de Saúde Pública que apresentam escassos recursos humanos e materiais.

Foi realizado um levantamento de ocorrência de aflatoxinas B" B2' G" G" ocratoxina A e zearalenona em produtos alimentícios comercializados nas cidades de Rio Grande e Pelotas, RS. As amostras, produtos de arroz (47), milho (39) e trigo (79), foram coletadas em supermercados nos anos de 1996 e 1997. Foi empregado o multimetodo de camada delgada descrito por Soares (1987). A performance deste para cada tipo de produto estudado foi avaliada e os indicadores foram semelhantes aos da literatura para este tipo de método. Os resultados mostraram que 6,7% das amostras estavam contaminadas por micotoxinas. Os produtos de milho foram os que apresentaram níveis de aflatoxina B, (32 ug.Kg' ) acima dos limites permitidos pela legislação brasileira. Ocratoxina A foi encontrada em amostras de arroz (48 e 19 ug.Kg') e trigo (18 e 26 ug.Kg'). Zearalenona esteve presente em amostras de milho (163 ug.Kg' ) e farinhas de trigo (105 e 97 ug.Kg').

The Jigsaw Learning Model to Promote Engagement in the English Language Classroom: A Teacher’s Reflection
Authors: Suwartono Tono , Romdona Yaomal
Published: February 2024

Learning activities employing the lecture model have induced boredom among students and resulted in poor participation in the classroom, including in the English as a foreign language class. Low student participation in classrooms may impede the development of their skills. The jigsaw cooperative learning model provides an opportunity for students to collaborate and actively participate. This collaborative action research aims to assist students in addressing engagement issues in English lessons through the jigsaw cooperative learning model. The collaborative action research involved a cohort of 36 primary school students, comprising 20 females and 16 males, in the city of Purwokerto, Indonesia. Data was collected through observation, and the observational data obtained were then analyzed using descriptive statistics. After three cycles, student engagement increased from 56% (baseline) to 65.56%, 75.56%, and 79.44%, respectively. The desired criteria for intervention success (75%) were met in cycle 2, leading to the conclusion of the investigation in cycle 3. Based on the results, it can be inferred that the adoption of the jigsaw learning model has effectively enhanced student engagement in the English language class. Practical implications of the study are then presented.
Pengaruh Monosodium Glutamat Terhadap Pertumbuhan Vegetatif Tanaman Cabai Setan di Tanah Latosol
Authors: Faustina Ega , Febriyono Wahyu , Prayitno Restu Agus
Published: February 2024

Tanaman cabai memiliki nilai ekonomis yang tinggi karena tingkat konsumsi dikalangan masyarakat sangat tinggi. Tanah latosol pada umumnya adalah tanah yang mengalami pencucian lanjut sehingga fosfor (P) dalam tanah bersifat asam dan terikat dalam bentuk senyawa Al-P dan Fe-P. Pemupukan yang intensif di tanah Latosol diperlukan guna menambah kesuburan ditanah dan meningkatkan produksi cabai setan. MSG adalah salah satu alternatife pupuk yang dapat digunakan karena mengandung unsur makro yang dibutuhkan tanaman. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh MSG terhadap peningkatan pertumbuhan vegetatif tanaman cabai setan di tanah latosol. Penelitian ini dilaksanakan di Green House Universitas Peradaban, Kecamatan Paguyangan, Kabupaten Brebes, Jawa Tengah. Penelitian ini menggunakan Rancangan Acak Kelompok Lengkap 3 x 3 faktorial. Faktor pertama adalah dosis pupuk NPK (0 gr, 1 gr, 2 gr), sedangkan faktor kedua adalah dosis MSG (0 gr, 2 gr, 4 gr) sehingga total diperoleh 9 kombinasi perlakuan. Parameter yang diamati adalah pertambahan tinggi tanaman, pertambahan jumlah daun, dan pertambahan diameter batang tanaman. Hasil penelitian menunjukan bahwa tidak ditemukan adanya interaksi antara perlakuan pupuk NPK dengan perlakuan pupuk MSG. Pemberian Monosodium Glutamat 4 gr/ tanaman dapat meningkatkan tinggi tanaman sebanyak 14,07 cm dan jumah daun sebanyak 9 helai tanaman cabai setan dibandingkan dengan kontrol, sedangkan pemberian NPK 2 gr/ tanaman dapat meningkatkan tinggi tanaman 15,85 cm, jumlah daun sebanyak 10 helai, dan diameter batang sebanyak 1,5 cm tanaman cabai setan.
