Surface waterlogging reduces the patency of wheeled energy vehicles involved in the transportation of crops from the fields. At the same time, it should be noted that currently there is an acute shortage of wheeled power vehicles of high cross-country ability to perform the duties assigned to them for the transportation of agricultural goods. Based on the analysis of operational modes, structural capabilities of cars and the current state of the art, a design was proposed - a "Device for towing an on-board semi-trailer", which makes it possible to aggregate a serial high-terrain vehicle equipped with a winch device, with an on-board semi-trailer as part of transport and reloading modules, and capable of transferring part of its own load of the aggregated semi-trailer through loading the support bracket-drawbar and winch device to the running system, driving wheels and frame towing vehicle-a car in order to increase its cross-country ability, reduce slipping, increase productivity when performing work. The article offers a theoretical calculation of the operation of the proposed device, considers the reactions of the surface of motion, emerging and interacting force factors, which makes it possible to substantiate the geometric and power elements of its design.

An Intersection: The Contract Review Process, Measurement Decision Risk, and Measurement Uncertainty
Authors:   Rockwell Collins Inc., Gossman Travis
Published: March 2022

At the 2007 NCSLI Workshop and Symposium, Dr. Howard Castrup, in his presentation on ANSI/NCSL Z540.3, remarked to the audience "Don’t just make us report measurement uncertainty and then do nothing with that value." Ten years after that presentation, the calibration industry still struggles to heed Dr. Castrup’s advice. Much confusion remains on why there is more than just reporting an uncertainty value. There are three key areas that will be looked at in this paper: The contract review process, measurement uncertainty, and measurement decision risk. The goal is to inform the reader how these three concepts are related to each, how they affect the overall calibration process, and why this is important. Both the customer and the calibration lab have a responsibility to ensure that the proper measurement decision risk levels are set, communicated, and understood. Once the risk level is established and communicated, the calibration lab will then perform a calibration service that stays within the bounds of that risk level. The goal is to produce a calibration service that is both traceable and meets the customer's measurement decision risk requirement. And lastly, a calibration report must be generated containing the appropriate information.

Abstract. DMS emitted from the sea water is a key precursor to new particle formation, acting as a regulator in Earth’s warming climate system. However, DMS’s effects are not well understood in various ocean regions. In this study, we estimated DMS emissions based on a machine learning method and used the GEOS-Chem global 3D chemical transport model coupled with the TwO Moment Aerosol Sectional (TOMAS) microphysics scheme to simulate the atmospheric chemistry and radiative effects of DMS. The contributions of DMS to atmospheric SO42- aerosol and cloud condensation nuclei (CCN) concentrations along with their radiative effect over the Asian region were evaluated for the first time. Firstly, we constructed novel monthly-resolved DMS emissions (0.5° × 0.5°) for the year 2017 using a machine learning model. 4351 seawater DMS measurements (including the recent ones over the Chinese Sea) and 12 relevant environment parameters were selected for training. We found the model could predict the observed DMS concentrations with a correlation coefficient of 0.75 and fill the values in regions lack of observations. Across Asian Seas, the highest seasonal mean DMS concentration occurred in Mar-Apr-May (MAM), and we estimate annual DMS emission flux of 1.25 Tg (S), which accounts for 15.4 % of anthropogenic sulfur emissions over the entire simulation domain (covers most of Asia) in 2017. The model estimates of DMS and methane sulfonic acid (MSA), using updated DMS emissions, were evaluated by comparing with cruise survey experiments and long-term online measurement site data. The improvement in model performance can be observed compared with the global-database DMS emissions. The relative contributions of DMS to SO42- and CCN were higher in remote oceanic areas, which reached up to 88 % and 42 % of all sources. Correspondingly, the sulfate direct radiative forcing (DRF) and indirect radiative forcing (IRF) contributed by DMS ranged from -200 to -20 mW m-2 and -900 to -100 mW m-2, respectively, with levels varying by season. The strong negative IRF is mainly over remote ocean regions ( -900 to -600 mW m-2). Generally, the magnitude of IRF derived by DMS was twice as large as its DRF. This work provides insights into the source strength of DMS and its impact on climate, addressing knowledge gaps related to factors controlling aerosols in the marine boundary layer and their climate impacts.
Novel assessment of numerical forecasting model relative humidity with satellite probabilistic estimates

Published: March 2022

Abstract. A novel method of comparison between an atmospheric model and satellite
probabilistic estimates of relative humidity (RH) in the tropical atmosphere
is presented. The method is developed to assess the Météo-France
numerical weather forecasting model ARPEGE (Action de Recherche Petite Echelle Grande Echelle) using probability density
functions (PDFs) of RH estimated from the SAPHIR (Sondeur Atmosphérique du
Profil d'Humidité Intertropicale par Radiométrie) microwave sounder. The
satellite RH reference is derived by aggregating footprint-scale
probabilistic RH to match the spatial and temporal resolution of ARPEGE over
the April–May–June 2018 period. The probabilistic comparison is discussed
with respect to a classical deterministic comparison confronting each model
RH value to the reference average and using a set confidence interval. This
study first documents the significant spatial and temporal variability in
the reference distribution spread and shape. We demonstrate the need for a
finer assessment at the individual case level to characterize specific
situations beyond the classical bulk comparison using determinist “best”
reference estimates. The probabilistic comparison allows for a more
contrasted assessment than the deterministic one. Specifically, it reveals
cases where the ARPEGE-simulated values falling within the deterministic
confidence range actually correspond to extreme departures in the reference
distribution, highlighting the shortcomings of the too-common Gaussian
assumption of the reference, on which most current deterministic comparison
methods are based.
A case study of a ducted gravity wave event over northern Germany using simultaneous airglow imaging and wind-field observations

Abstract. An intriguing and rare gravity wave event was recorded on the night of 25 April 2017 using a multiwavelength all-sky airglow imager over northern
Germany. The airglow imaging observations at multiple altitudes in the
mesosphere and lower thermosphere region reveal that a prominent upward-propagating wave structure appeared in O(1S) and O2 airglow
images. However, the same wave structure was observed to be very faint in OH airglow images, despite OH being usually one of the brightest airglow
emissions. In order to investigate this rare phenomenon, the altitude
profile of the vertical wavenumber was derived based on colocated meteor
radar wind-field and SABER temperature profiles close to the event location.
The results indicate the presence of a thermal duct layer in the altitude
range of 85–91 km in the southwest region of Kühlungsborn, Germany.
Utilizing these instrumental data sets, we present evidence to show how a
leaky duct layer partially inhibited the wave progression in the OH airglow
emission layer. The coincidental appearance of this duct layer is responsible for the observed faint wave front in the OH airglow images compared O(1S) and O2 airglow images during the course of the night over northern Germany.
Combining seismic signal dynamic inversion and numerical modeling improves landslide process reconstruction

Published: March 2022

Abstract. Landslides present a significant hazard for humans, but continuous landslide monitoring is not yet possible due to their unpredictability. Post-event reconstruction based on field survey and remote sensing cannot provide full insight into the landslide movement process. Analysis and inversion of the seismic signals generated by landside movement has started to provide valuable data for understanding the entire process of landslide movement, from initiation to cessation, along with numerical simulation, but each method has shortcomings. Simple seismic signal analysis can detect landslide occurrence, but the propagation effect generates lags. Dynamic inversion based on long-period seismic signals gives the low-frequency curve of landslide dynamic parameters, but not the high-frequency characteristics. Numerical simulation can simulate the entire movement process, but results are strongly influenced by choice of model parameters. Developing a method for combining the three techniques has become a focus for research in recent years. Here, we develop such a protocol based on analysis of the 2018 Baige landslide (China). Seismic signal dynamic inversion results are used to verify the numerical simulation, and then the numerical simulation is dynamically constrained and optimized to obtain the best numerical value. We apply the procedure to the Baige event and, combined with field/geological survey, show it provides a comprehensive and accurate method for dynamic process reconstruction. We found that the Baige landslide was triggered by detachment of the weathered layer, with severe top fault segmentation. The landslide process comprised four stages: initiation, main slip, blocking, and deposition. Multi-method mutual verification effectively reduces the inherent ambiguity of each method, and multi-method joint analysis improves the rationality and reliability of the results. The approach outlined in this study could be used to support hazard prevention and control in sensitive areas.

Abstract. Knowledge about muon tomography has spread in recent years in the
geoscientific community and several collaborations between geologists and
physicists have been founded. As the data analysis is still mostly done by
particle physicists, much of the know-how is concentrated in particle
physics and specialised geophysics institutes. SMAUG (Simulation for Muons
and their Applications UnderGround), a toolbox consisting
of several modules that cover the various aspects of data analysis in a muon
tomographic experiment, aims at providing access to a structured data
analysis framework. The goal of this contribution is to make muon tomography
more accessible to a broader geoscientific audience. In this study, we show
how a comprehensive geophysical model can be built from basic physics
equations. The emerging uncertainties are dealt with by a probabilistic
formulation of the inverse problem, which is finally solved by a Monte Carlo
Markov chain algorithm. Finally, we benchmark the SMAUG results against
those of a recent study, which, however, have been established with an
approach that is not easily accessible to the geoscientific community. We
show that they reach identical results with the same level of accuracy and
precision.
Evaporation enhancement drives the European water-budget deficit during multi-year droughts
Authors: Massari Christian , Avanzi Francesco , Bruno Giulia , Gabellani Simone , Penna Daniele , Camici Stefania
Published: March 2022

Abstract. In a warming climate, periods with lower than average
precipitation will increase in frequency and intensity. During such periods,
known as meteorological droughts, the decline in annual runoff may be
proportionally larger than the corresponding decline in precipitation.
Reasons behind this exacerbation of runoff deficit during dry periods remain
largely unknown, and this challenges the predictability of when this
exacerbation will occur in the future and how intense it will be. In this
work, we tested the hypothesis that runoff deficit exacerbation during
droughts is a common feature across climates, driven by evaporation
enhancement. We relied on multidecadal records of streamflow and
precipitation for more than 200 catchment areas across various European climates,
which distinctively show the emergence of similar periods of exacerbated
runoff deficit identified in previous studies, i.e. runoff deficit on the
order of −20 % to −40 % less than what expected from precipitation
deficits. The magnitude of this exacerbation is two to three times larger for
basins located in dry regions than for basins in wet regions, and is
qualitatively correlated with an increase in annual evaporation during
droughts, in the order of +11 % and +33 % over basins characterized
by energy-limited and water-limited evaporation regimes, respectively. Thus,
enhanced atmospheric and vegetation demand for moisture during dry periods
induces a nonlinear precipitation-runoff relationship for low-flow regimes,
which results in an unexpectedly large decrease in runoff during periods of
already low water availability. Forecasting onset, magnitude, and duration
of these drops in runoff have paramount societal and ecological
implications, especially in a warming climate, given their supporting role
for safeguarding water, food, and energy. The outcome that water basins are
prone to this exacerbation of runoff deficit for various climates and
evaporation regimes makes further understanding of its patterns of
predictability an urgent priority for water-resource planning and management
in a warming and drier climate.

Abstract. Inversion tillage is a commonly applied soil cultivation practice in Europe, which though has been blamed for deteriorating topsoil stability and organic carbon (OC) content. In this study, the potential to reverse these negative effects in the topsoil by alternative agricultural management practices are evaluated in five long-term experiments (running from 8 to 54 years the moment of sampling) in Europe. Topsoil samples (0–15 cm) were collected and analysed to evaluate the effects of conservation tillage (reduced and no-tillage) or increased organic inputs of different origin (farmyard manure, compost, crop residues) combined with inversion tillage on topsoil stability, soil aggregates and within these, OC distribution. Effects from the treatments on the two main components of organic matter i.e., particulate (POM) and mineral associated (MAOM), were also evaluated. Reduced and no-tillage practices, as well as the additions of manure or compost, increased the aggregates mean weight diameter (MWD) and topsoil OC, as well as the OC corresponding to the different aggregate size fractions. The incorporation of crop residues had a positive impact on the MWD but a less profound effect on OC content both on total OC and on OC associated with the different aggregates. A negative relationship between the mass and the OC content of the microaggregates (53–250 μm) was identified in all experiments. There was no effect on the mass of the macroaggregates and the occluded microaggregates (mM) within these, while the corresponding OC contents increased with less tillage and more organic inputs. Inversion tillage led to less POM within the mM, whereas the different organic inputs did not affect it. In all experiments where the total POM increased, the total soil organic carbon (SOC) was also affected positively. We concluded that the negative effects of inversion tillage on topsoil can be mitigated by reducing the tillage intensity or by adding organic materials, optimally combined with non-inversion tillage methods.
Predicting the steady-state isochronal stratigraphy of ice shelves using observations and modeling

Published: March 2022

Abstract. Ice shelves surrounding the Antarctic perimeter decelerate ice discharge towards the ocean through buttressing. Ice-shelf evolution and integrity depend on the local surface accumulation, basal melting and on the spatially variable ice-shelf viscosity. These parameters are often poorly constrained by observations and introduce uncertainties in ice-sheet projections for the ice-sheet evolution. Isochronal radar stratigraphy is an observational archive for the atmospheric, oceanographic and ice-flow history of ice shelves with potential to assist model calibration. Here, we explore the possibility of using a simple and observationally driven ice-flow forward model to predict the ice-shelf stratigraphy for a given atmospheric- and oceanographic scenario. We validate this approach with the full Stokes ice-flow model Elmer/Ice and present a test case for the Roi Baudouin Ice Shelf (East Antarctica), where we compare model predictions with radar observations. The presented method enables us to investigate whether ice shelves are in steady-state and to delineate how much of the ice-shelf volume is determined by its local surface accumulation. This can be used to better understand variability in ice-shelf rheology and for estimations which ice shelves are particularly susceptible to changes of surface accumulation rates in the future. Moreover, the numerically efficient prediction of isochronal stratigraphy is a step forward towards integrating radar data into ice-flow models using inverse methods. This has potential to constrain ocean-induced melting beneath Antarctic ice shelves using the ever-growing archive of radar observations of internal ice stratigraphy.

Published: March 2022

Student’s grade retention is a key issue faced by many education systems, especially those in developing countries. In this paper, we seek to gauge the relevance of students’ personality traits in predicting grade retention in Brazil. For that, we used data collected in 2012 and 2017, in the city of Sertaozinho, countryside of the state of Sao Paulo, Brazil. The surveys taken in Sertaozinho included several socioeconomic questions, standardized tests, and a personality test. Moreover, students were in grades 4, 5, and 6 in 2012. Our approach was based on training machine learning models on the surveys’ data to predict grade retention between 2012 and 2017 using information from 2012 or before, and then using some strategies to quantify personality traits’ predictive power. We concluded that, besides proving to be fairly better than a random classifier when isolated, personality traits contribute to prediction even when using socioeconomic variables and standardized tests results.
Population Dynamics for Discrete Wasserstein Gradient Flows over Networks
Authors: Diaz-Garcia Gilberto , Uribe Cesar , Quijano Nicanor
Published: March 2022

We study the problem of minimizing a convex function over probability measures supported in a graph. We build upon the recent formulation of optimal transport over discrete domains to propose a method that generates a sequence that provably converges to a minimum of the objective function and smoothly transports mass over the edges of the graph. Moreover, we identify novel relation between Riemannian gradient flows and perturbed best response protocols that provide sufficient conditions for the convergence of the proposed algorithm. Numerical results show practical advantages over existing approaches with respect to the implementability and convergence rates.

We develop a generative neural network for the generation of sparse data in particle physics using a permutation invariant and physics-informed loss function. The input dataset used in this study consists of the particle constituents of hadronic jets due to its sparsity and the possibility of evaluating the network’s ability to accurately describe the particles and jets properties. A variational autoencoder composed of convolutional layers in the encoder and decoder is used as the generator. The loss function consists of a reconstruction error term and the Kullback-Leibler divergence between the output of the encoder and the latent vector variables. The permutation invariant loss on the particles’ properties is combined with two mean-squared error terms that measure the difference between input and output jets mass and transverse momentum, which improves the network’s generation capability as it imposes physics constraints, allowing the model to learn the kinematics of the jets.
University Students’ Positive and Negative Perceptions of Lifelong Learning: A Metaphoric Analysis
Authors: DEVECİ Tanju , BEDİRHANOĞLU İdris
Published: March 2022

In tertiary education, lifelong learning (LL) skills alongside technical skills need to be prioritized. Is it, however, correct to assume that all university students are familiar with LL? Even so, might some students believe that LL is a source of tension? One way to understand these aspects is through metaphors, commonly used to convey the meaning individuals attach to concepts. Thus, this study investigated 229 university students’ metaphoric perceptions of LL. Data were collected using a discourse completion task. Results revealed that the students had limited understanding of LL as reflected through their chosen metaphors. The metaphors most frequently used to define LL were “tree,” “life,” “universe” and “trip.” The students’ explanations pointed to a variety of attributes of LL, “continuity,” “limitlessness,” and “expansion of horizons” being the most frequent ones. There were also metaphors and attributes denoting negative perceptions. We recommend LL skills be made an integral part of curricula to enhance students’ potential for becoming lifelong learners.
"What we raise ourselves": Growing food sovereignty in the Mississippi Delta
Authors: Holmes Emily , Campbell Mary , Betz Ryan
Published: March 2022

This paper employs the concept of food sover­eignty, as conceived by La Via Campesina and developed by First Nations in North America and peasant farmer groups around the world, as a lens to assess the level of local control over the produc­tion, distribution, and consumption of food in the Mississippi Delta. We present research conducted through site visits, participant observation, focus groups, and surveys of communities affiliated with the Delta EATS public school garden program cur­rently operating in three Mississippi public elemen­tary schools. Our findings demonstrate low levels of food sovereignty but high levels of agency and ingenuity in accessing and obtaining desired foods, along with abundant interest in preserving and passing on traditional foodways. Community mem­bers express the desire to exert greater local control over food production, distribution, and consump­tion through community gardens, farmers markets, and cooking and food preservation classes. While food sovereignty is constrained by the current agri-food system of the Delta, programs such as Delta EATS and farmers cooperatives are enhancing local food sovereignty through farm-to-school programs that strengthen relationships between farmers and the community.

Propsilocerus Kieffer, 1923 shares morphological synapomorphies with Prodiamesinae
Authors: Baranov Viktor
Published: March 2022

In their comprehensive analysis Cranston et al. (2012) quite unexpectedly recovered a monophyletic Orthocladiinae, except that Propsilocerus Kieffer, 1923, was recovered as a representative of Prodiamesinae. In this short communication I show that Propsilocerus shares morphological synapomorphies with other Prodiamesinae – namely (i) an indirect tracheal connection of the pupal thoracic horn to the adult spiracle and (ii) a parallel-sided rami of female gonapophysis IX.
A home at last! Changania choui Tseng, 1965 belongs to Thienemanniella Kieffer, 1911 (Diptera: Chironomidae: Orthocladiinae)
Authors: Spies Martin , Borkent Art , Cranston Peter S. , Lin Xiao-Long , Tang Hong-Qu
Published: March 2022

The midge Changania choui Tseng, 1965 (Insecta, Diptera, Nematocera), originally described in the family Cecidomyiidae and recently transferred to the Ceratopogonidae, is recognised as an adult female in the Chironomidae, subfamily Orthocladiinae. The type material is missing, and the published description and illustrations are limited. Although the genus name Changania Tseng, 1965 becomes a new junior synonym of Thienemanniella Kieffer, 1911, Thienemanniella choui (Tseng 1965), new combination, should be treated as a nomen dubium.

Aim: To determine the relation between prevalence of Postpartum Depression and varying degrees of severity of Hypertensive Disorders in Pregnancy. Study design: A cross sectional study . Place & duration of study: Department of Obs. & Gynae, Avicenna Hospital, Lahore from June 2020 to December 2021. Methodology: A total of 220 women with and without hypertensive disorders of pregnancy (110 in each group) delivered during this period were enrolled in the study. A survey in the post partum period from second to sixth week postpartum was carried out. It was done according to the Edinburgh Postnatal Depression Scale (EPDS) to assess the effect of severity of Hypertensive disorders of pregnancy to develop new-onset postpartum depression. Results: 220 women were enrolled in the study. Among them Forty five women showed sign and symptoms of post partum depression. On the other hand 175 had no manifestation of depression according to the scale. The prevalence of PPD was 27 % (30/110) in women with hypertensive disorders, being twice the value in normotensive subjects (13.6%). The risk of Post partum depression surged with the aggressiveness of hypertensive disease in pregnancy. Conclusion: Preeclampsia has an independent association with Post partum depression. The risk of Post partum depressive disorder seemed to increase with the rising severity of hypertension in pregnancy. Therefore support and additional preventive strategies should be planned for women with Preeclampsia to reduce the likelihood of Post partum deterioration of mental health. Keywords: Hypertensive disorders in Pregnancy, Preeclampsia , Postpartum Depression.

Background: Diabetes type 2 and periodontitis has bi-directional relationship not only diabetes is a risk factor for periodontitis but periodontitis could have negative effect on glycemic control. Poor glycemic control is associated with reduced salivary pH. Aim: To compare the difference in salivary PH in patients with Periodontitis with or without Diabetes mellitus (Type 2). Method: A total of 348 consenting subjects were recruited for this investigation. There were 116 with diabetes mellitus and periodontitis, 116 with periodontitis but not diabetes and 116 patients with no periodontitis and diabetes. Salivary PH strips were used to determine the PH levels in each participant and recorded. Results: Participants with periodontitis and diabetes had decreased salivary PH of 6.16 ± 0.03 when compared with individuals with periodontitis who were not diabetic who had PH of 6.62 ± 0.04. The mean salivary PH was compared between the three groups (Control, Periodontitis and DM) where a statistically significant relationship was determined (P<0.05). Conclusion: Our study concluded that the salivary PH of patients with DM and periodontitis is lower than that of the control group. The difference in mean PH value between group 1, group 2 and group3 was statistically significant (P<0.05). Keywords: Periodontitis, Diabetes mellitus, salivary PH
Response of Homogeneous Conducting Sphere in Non-Integer Dimensional Space
Authors: Ahmed Saeed , Akbar M , Shahzad M Imran
Published: March 2022

In this paper, we have investigated electric potential and field analytically for homogeneous conducting sphere by solving the Laplacian equation in fractional dimensional space. The laplacian equation in fractional space describes complex phenomena of physics. The separation variable method is used to solve the Laplace differential equation. The mathematical formulae governing the interaction of a low-frequency source of electric current with a spherical anomaly are derived in fractional dimensional space. These formulae are used to determine the apparent resistivity and induced-polarization response. The potential due to the current point source in fractional space is derived using Gegenbauer polynomials. The electric field inrensity of the homogeneous conducting sphere is calculated using the electric potential due to a current point source outside the sphere. The results are compared analytically with classical results by setting the fractional parameter α=3.
