The multiple linear regression modelling algorithm ABSOLUT v1.0 for weather-based crop yield prediction and its application to Germany at district level
Authors: Conradt Tobias
Published: March 2021

Abstract. ABSOLUT v1.0 is an adaptive algorithm that uses correlations between time-aggregated weather data and crop yields for yield prediction. At its core, locally (i.e. district-) specific multiple linear regressions are used to predict the annual crop yield based on four weather aggregates and a linear trend in time. In contrast to other statistical yield prediction methods, the input weather features are not predefined or based on a limited number of observed correlations but they are exhaustively tested for maximum explanatory power across all of their possible combinations in all districts of the modelling domain. Principal weather variables (such as temperature, precipitation, or sunshine duration) are aggregated over two to six consecutive months from the 12 months preceding the harvest. This gives 45 potential input features per original weather variable. In a first step, this zoo of possible input features is subset to those very probably holding explanatory power for observed yields. The second, computationally demanding step is making out-of-sample predictions for all districts with all possible combinations of the remaining features. Step three selects the seven combinations of four different weather features that have the highest explanatory power averaged over the districts. Finally, the district-specific best performing regression among these seven is used for district predictions, and the results can be spatially aggregated. To evaluate the new approach, ABSOLUT v1.0 is applied to predict the yields of ten major crops at the district level in Germany based on two decades of yield and weather data from about 300 districts. When aggregated to the national level, the predictions explain 70–90 % of the observed variance between years depending on crop type and time frame considered. District-level performance maps for winter wheat and silage maize show areas with > 40 % variance explanation covering about two thirds of the country.

Abstract. The inclusion of soil wetness information in empirical landslide prediction models was shown to improve the forecast goodness of regional landslide early warning systems (LEWS). However, it is still unclear which source of information – numerical models or in-situ measurements – are of higher value for this purpose. In this study, soil moisture dynamics at 133 grassland sites in Switzerland were simulated for the period of 1981 to 2019 using a physically-based 1D soil moisture transfer model (CoupModel). A common parametrization set was defined for all sites except for site-specific soil hydrological properties, and the model performance was assessed at a subset of 14 sites where in-situ soil moisture measurements were available on the same plot. A previously developed statistical framework was applied to fit an empirical landslide forecast model, and ROC analysis was used to assess the forecast goodness. To assess the sensitivity of the landslide forecasts, the statistical framework was applied to different CoupModel parametrizations, to various distances between simulation sites and landslides, and to measured soil moisture from a subset of 35 sites for comparison with a measurement-based forecast model. We found that (i) simulated soil moisture is a skilful predictor for regional landslide activity, (ii) that it is sensitive to the formulation of the upper and lower boundary conditions, and (iii) that the information content is strongly distance-dependent. Compared to a measurement-based landslide forecast model, the model-based forecast performs better as the homogenization of hydrological processes and the site representation can lead to a better representation of triggering event conditions. However, it is limited in reproducing critical antecedent saturation conditions due to an inadequate representation of the long-term water storage.
The value of water isotope data on improving process understanding in a glacierized catchment on the Tibetan Plateau

Published: March 2021

Abstract. This study integrated a water isotope module into the hydrological model THREW which has been successfully used in high and cold regions. Signatures of oxygen stable isotope (18O) of different water inputs and stores were simulated coupling with the simulations of runoff generations. Isotope measurements of precipitation water samples and global precipitation isotope product, as well as assumed constant isotope signature of ice meltwater were used to force the isotope module. Isotope signatures of water stores such as snowpack and subsurface water were updated by an assumed completely mixing procedure. Fractionation effects of snowmelt and evapotranspiration were modeled in a Rayleigh fractionation approach. The isotope-aided model was subsequently applied for the quantifications of runoff components and estimations of mean water travel time (MTT) and mean residence time (MRT) in the glacierized watershed of Karuxung River on the Tibetan Plateau. Model parameters were constrained by three different combinations of observations including a single-objective calibration using streamflow measurement solely, a dual- objective calibration using both streamflow measurement and MODIS estimated snow cover area, and a triple- objective calibration using additionally isotopic composition of stream water. Modeled MTT and MRT was validated by estimate of a tracer-based sine-wave method. Results indicate that: (1) the proposed model performed quite well on simultaneously reproducing the observations of streamflow, snow cover area, and isotopic composition of stream water, despite that only precipitation water samples were available for tracer input; (2) isotope data helped to estimate more plausible contributions of runoff components (CRCs) to streamflow in the melting season, and improved the robustness of MTT and MRT estimations; (3) involving isotope data for the model calibration obviously reduced uncertainties of the quantification of CRCs and estimations of MTT and MRT, through better constraining the strong competitions among different runoff processes induced by meltwater and rainfall. Our results inform high value of water isotope data on improving process understanding in a glacierized basin on the Tibetan Plateau.
Bootstrap Aggregation for Model Selection in the Model-free
Formalism
Authors: Crawley Timothy , Palmer III Arthur G.
Published: March 2021

Abstract. The ability to make robust inferences about the dynamics of biological macromolecules using NMR spectroscopy depends heavily on the application of appropriate theoretical models for nuclear spin relaxation. Data analysis for NMR laboratory-frame relaxation experiments typically involves selecting one of several model-free spectral density functions using a bias-corrected fitness test. Here, advances in statistical model selection theory, termed bootstrap aggregation or bagging, are applied to 15N spin relaxation data, developing a multimodel inference solution to the model-free selection problem. The approach is illustrated using data sets recorded at four static magnetic fields for the bZip domain of the S. cerevisiae transcription factor GCN4.

Published: March 2021

Abstract. Mega-gullies and landslides pose significant hazards to urban development on steep terrain. Water resources infrastructure failures (WRIFs), such as leaks and breaks in water supply pipes, have been postulated as a trigger of mass movement events but data for validation has been challenging to acquire since earthwork proceeds quickly after events to repair roads and other infrastructure. Urban development in Tijuana, Mexico was monitored for a five-year period to document the occurrence of mega-gullies and landslides, including sediment volumes. A rapid assessment approach was developed based on photogrammetric observations from an unmanned aerial vehicle (UAV) and Structure from Motion (SfM) digital processing. Three hazardous mass-movement events were observed including two mega-gullies and one landslide. Furthermore, all three events were linked to WRIFs. Frequency analysis points to the annual probability of a WRIF-based erosion event in the range of 40–60 %, which is far higher than design levels typically used for urban stormwater infrastructure (5–10 %). Additionally, sediment modelling points to WRIF-based erosion as a non-negligible contributor to sediment generation. These results suggest that WRIFs are a significant contributor to erosion hazards facing urban development on steep terrain, and call for expanded monitoring to characterize the occurrence and modes of WRIF-based erosion events.
Evolution of surface deformation related to salt-extraction-caused sinkholes in Solotvyno (Ukraine) revealed by Sentinel-1 radar interferometry

Published: March 2021

Abstract. Rock salt has remarkable mechanical properties and high
economic importance; however, the strength of salt compared to other rocks
makes it a rather vulnerable material. Human activities could lead to
acceleration of the dissolution of soluble rock salt and collapse of
subsurface caverns. Although sinkhole development can be considered a local
geological disaster regarding the characteristic size of surface depressions,
the deformations can result in catastrophic events. In this study we report
the spatiotemporal evolution of surface deformation in the Solotvyno salt
mine area in Ukraine based on Sentinel-1 interferometric synthetic aperture
radar measurements. Although the mining operations were finished in 2010,
several sinkholes have been opened up since then. Our results show that
despite the enormous risk management efforts, the sinkholes continue to
expand with a maximum line-of-sight deformation rate of 5 cm/yr. The
deformation time series show a rather linear feature, and unfortunately no
slowdown of the processes can be recognized based on the investigated 4.5-year-long data set. We utilized both ascending and descending satellite
passes to discriminate the horizontal and vertical deformations, and our
results revealed that vertical deformation is much more pronounced in the
area. Analytical source modeling confirmed that the complex deformation
pattern observed by Sentinel-1 radar interferometry has a direct connection
to the former mining activity and is confined to the mining territory. With
the 6 d repetition time of Sentinel-1 observations, the evolution of
surface changes can be detected in quasi real time, which can facilitate
disaster response and recovery.
Drought impact in the Bolivian Altiplano agriculture associated with the El Niño–Southern Oscillation using satellite imagery data

Published: March 2021

Abstract. Drought is a major natural hazard in the Bolivian
Altiplano that causes large agricultural losses. However, the drought effect
on agriculture varies largely on a local scale due to diverse factors such
as climatological and hydrological conditions, sensitivity of crop yield to
water stress, and crop phenological stage among others. To improve the
knowledge of drought impact on agriculture, this study aims to classify
drought severity using vegetation and land surface temperature data, analyse
the relationship between drought and climate anomalies, and examine the
spatio-temporal variability of drought using vegetation and climate data.
Empirical data for drought assessment purposes in this area are scarce and
spatially unevenly distributed. Due to these limitations we used vegetation,
land surface temperature (LST), precipitation derived from satellite
imagery, and gridded air temperature data products. Initially, we tested the
performance of satellite precipitation and gridded air temperature data on a
local level. Then, the normalized difference vegetation index (NDVI) and LST
were used to classify drought events associated with past El
Niño–Southern Oscillation (ENSO) phases. It was found that the most
severe drought events generally occur during a positive ENSO phase (El
Niño years). In addition, we found that a decrease in vegetation is
mainly driven by low precipitation and high temperature, and we identified
areas where agricultural losses will be most pronounced under such
conditions. The results show that droughts can be monitored using satellite
imagery data when ground data are scarce or of poor data quality. The
results can be especially beneficial for emergency response operations and
for enabling a proactive approach to disaster risk management against
droughts.
Maximal power per device area of a ducted turbine

Published: March 2021

Abstract. The aerodynamic design of a ducted wind turbine for maximum total power coefficient was studied numerically using the axisymmetric Reynolds-averaged Navier-Stokes equations and an actuator disc model. The total power coefficient characterizes the rotor power per total device area, rather than the rotor area. This is a useful metric to compare the performance of a ducted wind turbine with an open rotor and can be an important design objective in certain applications. The design variables included the duct length, the rotor thrust coefficient, the angle of attack of the duct cross-section, the rotor gap, and the axial location of the rotor. The results indicated that there exists an upper limit for the total power coefficient of ducted wind turbines. Using an Eppler E423 airfoil as the duct cross-section, an optimal total power coefficient of 0.69 was achieved at a duct length of about 15 % of the rotor diameter. The optimal thrust coefficient was approximately 0.9, independent of the duct length and in agreement with the axial momentum analysis. Similarly independent of duct length, the optimal normal rotor gap was found to be approximately the duct boundary layer thickness at the rotor. The optimal axial position of the rotor was near the rear of the duct, but moved upstream with increasing duct length, while the optimal angle of attack of the duct cross-section decreased.

Dukungan keluarga atau orang terdekat terutama suami kepada ibu hamil untuk mendukung tujuan P4K sangat dibutuhkan. Dalam hal ini suami berperan aktif untuk memotivasi ibu hamil untuk memeriksakan kehamilannya ke tenaga kesehatan untuk mendapatkan pelayanan. Tujuan penelitian ini mengetahui dan membandingkan semua teori-teori dari buku maupun jurnal yang berkaitan dengandukungan suami untuk melaksanakan program Perencanaan Persalinan dan Pencegahan Komplikasi (P4K). Desain penelitian ini adalah menggunakan metode studi literatur.Sumber data dalam penelitian ini menggunakan data sekunder yang didapat dengan melakukan studi literatur dari jurnal-jurnal yang sesuai dengan topik penelitian dari tahun 2013-2020 sebanyak 10 jurnal. Berdasarkan hasil literatur review yang dilakukan oleh penulis, dapat disimpulkan bahwa dari hasil literatur review diketahui bahwa dukungan suami kepada ibu hamil terhadap program P4K ini masih kurang, hal ini karena mayoritas suami adalah bekerja di luar rumah sehingga tidak memiliki waktu untuk mengantarkan istrinya periksa kehamilan ke bidan serta kurang memperhatikan kondisi kesehatan istrinya. Sebagian besar ibu hamil dan suami merencanakan persalinannya pada saat mendekati waktu persalinan. Saran diharapkan tenaga kesehatan dapat mengoptimalkan pemberian informasi kepada ibu hamil tentang Program Perencanaan Persalinan dan Pencegahan Komplikasi (P4K) pada saat ibu hamil memeriksakan kehamilannya dan dilakukan secara rutin sehingga ibu hamil akan selalu mengingatnya.

Impact of OPEC activities on the global oil market
Authors: Orynbekova Aidana
Published: March 2021

This article is devoted to the main problems of interstate cooperation in the oil industry and the high role of the influence of the Organization of Petroleum Exporting Countries (OPEC) on the world economy. Thus, the process of transformation of OPEC from an inactive and inconspicuous organization in the world oil market, as well as the struggle of its members for universal world domination in the oil market. The increased economic growth of some countries in the past years led to the fact that the demand for oil began to exceed the supply, but the relevance of today dictates its own rules against the backdrop of the growing coronavirus pandemic. It is at the turn of the day that the negative factors and consequences of the global pandemic and its impact on oil prices are most clearly visible. The oil giants of the world economy are the OPEC member countries, which, as the current picture shows, fully control their oil resources and oil prices. Moreover, the current picture shows that oil has become the subject of major global speculation, showing that not only economic growth, the integrity of the world economy and the world order are under threat, but also the entire world energy balance.

This article is devoted to certain issues of the procedure for the consideration of information and reports on economic offenses, in terms of the effectiveness of state control over the transferred materials to authorized bodies requiring additional checks and examinations.
So, with the introduction in 2014 of the new Criminal and Criminal Procedure Codes of the Republic of Kazakhstan, the procedure for considering information and reports on offenses has radically changed, in particular, this has affected economic offenses. These changes have generated a number of unresolved issues in the timing and procedure for conducting inspections (audits, etc.) based on materials sent by the law enforcement body to the competent regulatory authorities to determine the amount of damage. A number of unresolved legislative gaps have arisen, which lead to inadequate state control and poor efficiency of consideration of these materials.

The experiment was carried out in a completely randomized design with 10 treatments in a parcel divided in time. Each plot consisted of 5 plants for analysis. Data were subjected to analysis of variance and when significant compared by Scott-Knott test (p> 0.05). Variables related to plant growth and the area under the disease progress curve (AUDPC) were evaluated. Assessments were performed at 67, 74 and 82 days after transplantation. There was no reduction in AUDPC for treatments compared to control. As for plant height (cm), the best treatments were Pichia sp. and Gonytrichum sp. with an increase in relation to control of 29.70% and 18.24%, respectively, and increased leaf area (cm2) by 27.42% and 19.85%, respectively. B. subtilis, Pichia sp. and Gonytrichum sp., increased total biomass by 42.31%, 32.82% and 21.44%, respectively. The filtrates application from Pichia sp., Filtrate from Gonytrichum sp., C. carbonica 12CH and B. subtilis provided better performance in the development of passion fruit plants with an increase in the main morphological attributes. The results show that the use of bio products improves the development of seedlings, especially the use of yeast and saprophytic fungi by controlling the biochemical and physiological processes of plants during development.

Published: March 2021

Health professions programs heavily depend on experiential learning to prepare learners for practice within the healthcare system. Learners acquire a significant proportion of patient care skills as they participate in experiential learning activities. As the coronavirus disease 2019 (COVID-19) pandemic disrupts education globally, educators have been challenged to reexamine existing teaching approaches to minimize the impact on experiential educational outcomes. This article describes how educators from the College of Pharmacy and College of Medicine at Qatar University utilized nontraditional teaching methods to ensure the continuation of experiential learning despite the disruption due to the pandemic.
Contrasting Geochemistry of Apatite from Peridotites and Sulfide Ores of the Jinchuan Ni-Cu Sulfide Deposit, NW China

Published: March 2021

Apatite is present within both the hosting lherzolite and sulfide ore at the Jinchuan magmatic Ni-Cu sulfide deposit of northwest China. Apatite grains within the lherzolite are generally large and hexagonal (>200 μm) and are associated with interstitial phlogopite and amphibole. These apatite grains contain ~0.9 wt % F, ~1 wt % Cl, 6,800 to 14,500 ppm rare earth elements (REE) and have in situ δ18OV-SMOW values of 5.10 to 6.38‰, all of which are indicative of crystallization from an evolved silicate magma. In comparison, the massive and disseminated sulfide ores contain fine-grained apatite (<200 μm) that is associated with sulfide minerals, phlogopite, and albite. These apatite grains contain sulfide inclusions that are indicative of crystallization almost coevally with or slightly later than the sulfide minerals. They are Cl-rich apatite with an average Cl of 5.6 wt % but F concentrations are below the limit of detection. They contain 1,860 to 2,300 ppm REE and have in situ δ18OV-SMOW values of 5.62 to 6.47‰. These data suggest that the sulfide-associated apatite formed from F- and REE-depleted, Cl-bearing sulfide melts. The apatite within the lherzolite was overprinted by later hydrothermal fluids as evidenced by the presence of abundant rounded and needle-like monazite and rare allanite inclusions within the apatite that formed as a result of a coupled metasomatism-reprecipitation process shortly after crystallization. Altered and fresh apatite domains have similar δ18O values, suggesting that this alteration was induced by postmagmatic hydrothermal fluids.

The apatite within the lherzolite and sulfide ore crystallized from two conjugate immiscible silicate and sulfide melts, respectively. Rare earth elements and F were preferentially partitioning into silicate melts, whereas most volatile components were mainly partitioned into the sulfide melts. The silicate magmas from which apatite crystallized were rich in light REE (LREE) relative to heavy REE (HREE). Volatile components in the sulfide melts changed the physicochemical conditions to enable such high-density melts to migrate upward and finally settle in the shallow chamber with silicate rocks.
Evolution of the Magmatic-Hydrothermal System at the Santa Rita Porphyry Cu Deposit, New Mexico, USA: Importance of Intermediate-Density Fluids in Ore Formation

The Santa Rita porphyry Cu deposit in New Mexico, USA, is characterized by a stockwork of three vein types that differ in morphology, mineralogy, and associated alteration assemblages. Early quartz veins associated with potassic alteration are composed of recrystallized granular quartz grains that host ubiquitous hypersaline liquid and vapor-rich fluid inclusions. The early quartz likely formed at high (≳500°C) temperatures and lithostatic pressures. Hypogene Cu mineralization at Santa Rita is in sulfide veins that reopened or crosscut the early quartz veins. The sulfide veins are surrounded by alteration halos containing chlorite and K-feldspar. Rare quartz crystals are present in some of these chalcopyrite and pyrite veins. The cores of the quartz crystals contain hypersaline liquid and vapor-rich fluid inclusions, whereas the rims mostly contain hypersaline liquid inclusions. The quartz crystals are interpreted to have formed close to the ductile-brittle transition as a result of the pressure drop from lithostatic to hydrostatic conditions. Formation of the quartz crystals was postdated by the deposition of Cu sulfides. Grain boundaries between the quartz and the sulfide minerals are irregular in shape, with sulfide crosscutting growth zones in the quartz. The Cu sulfides are interpreted to have formed from intermediate-density fluids that form secondary fluid inclusion assemblages in all earlier-formed quartz types. Microthermometric investigations showed that these fluid inclusion assemblages homogenize at ~385° to 435°C by critical or near-critical behavior and have salinities of <10 wt % NaCl equiv. The precipitation of Cu sulfides occurred as a result of cooling of these fluids following their escape from the lithostatic into the hydrostatic realm. Retrograde quartz solubility caused the corrosion of earlier-formed quartz during Cu sulfide deposition. The youngest veins at Santa Rita are composed of quartz and pyrite. These veins are associated with intense sericite alteration that overprinted all earlier alteration assemblages. The late quartz hosts primary and secondary liquid-rich fluid inclusions, but no intermediate-density fluid inclusions were identified. This quartz vein type formed at temperatures <360°C and hydrostatic pressures. The paragenetic relationships show that hypogene Cu mineralization at Santa Rita postdated potassic alteration of the host rocks. The Cu mineralization was formed by cooling intermediate-density fluids with critical or near-critical densities as they escaped from lithostatic to hydrostatic conditions.

This study aims to test whether profitability acts as a moderating variable that is able to moderate the influence of the company growth and capital structure on the firm value. The independent variables used in this study are company growth and capital structure, while profitability is the moderating variable.The research sample was taken from manufacturing industrial companies listed on the Indonesia Stock Exchange (IDX) during the period 2016 - 2018. The study used panel data which is a combination of cross section and time series data, with data analysis using multiple regression.The results showed that company growth and profitability had a positive effect on the firm value, while capital structure had does not effect. The results of the analysis show that profitability does not moderate the effect of company growth and capital structure on the firm value, the interaction of company growth and capital structure with profitability has a negative impact on the firm value.
