A Case study - Splitting Supercells over Berlin on July 10, 2020
Authors: Feige Hendrik , Horn Christian , Gatzen Christoph
Published: March 2023

As known, the presence of vertical wind shear leads to the organization of supercell thunderstorms. Changes in the wind profile can affect isolated convection especially in the development stage and in relation to its behavior.

This study takes a closer look at the organization of storms initiating in an urban environment that can have impacts on public life and infrastructure. Therefore an exemplary weather event over east Germany should be discussed in greater detail. While considering our theoretical and conceptual knowledge about supercelluar convection, it is important to ask further questions about the given atmospheric parameters or the specific time of convective initiation, when covering these events. Also it is essential to be able to make statements about the static stability and the sources of moisture. The local effects of a region, that may have influences on the convective scale, can help us to explain observed short-term changes. Especially the DBZ radar reflectivity, as one of the most common nowcast tools, can provide useful insights into atmospheric dynamics in context to the current flow pattern.

By evaluating NWP model data and using different observations, a summary of the synoptic pattern will be given that set the stage for isolated thunderstorm development over Berlin on this day. With using our understanding of dynamics in relation to the storm scale, the accuracy of nowcasting these cells should be clarified. For this purpose, the concept of the dynamic split and the storm motion as predictive indicators will be applied. Could the convective mode have been estimated already in the forecast process?

The case study can be considered as a useful complement for nowcasting silimar events in the future.
Does Low-level Vertical Wind Shear Matter for Hail Production?
Authors: Kumjian Matthew , Lombardo Kelly , Nixon Cameron , Allen John
Published: March 2023

Vertical wind shear (or more precisely, bulk wind vector magnitude differences between specified altitudes) has long been used for severe convective storm science and forecasting, in part owing to its relative success in correlating to various storm behaviors and hazards. However, theoretical, modeling, and observational work has suggested that this success may arise because vertical wind shear is associated with and/or a proxy for other, more dynamically relevant environmental characteristics.

Recent research has explored various environmental controls on hail sizes in supercell storms, and found that vertical wind shear (and, by extension, hodograph shape) is an important determinant on a storm’s proclivity for hail production. Idealized numerical simulations of supercells showed that, as deep-layer shear increases (specifically, zonal shear in the 2-6 km AGL layer; this also means increased 0-6-km shear), the resulting broader updrafts increased hailstone residence time and thus size. Paradoxically, increasing the 0-2-km shear (predominantly, but not entirely, in the meridional direction) broadened the updraft but decreased hail size: increased southerly winds within the hail growth zone increased residence times along the main growth pathway. These studies left a lingering question: what is the underlying driver to changes in supercellular hail production, the low-level shear magnitude, its orientation relative to the deep-layer shear, or neither?    

To answer this question, we present the results of simple idealized numerical modeling experiments in which the low-level (0-2 km) vertical wind shear magnitudes and directions are systematically and independently varied, keeping all other environmental factors the same. The resulting storms are used to drive the Kumjian & Lombardo (2020) hailstone growth trajectory model. The simulations lead to differences in hail sizes produced, despite having identical 0-2-km shear values. Rather, the differences in storm motion and hodograph shape lead to markedly different low-level storm-relative wind profiles. As a consequence of varied low-level storm-relative wind speeds and directions, the mesocyclonic flow speeds and directions within the hail growth zone differ amongst the experiments, which directly affects residence times and thus hail growth.
EUMETSAT activities in training forecasters for using satellite data and applications
Authors: Strelec Mahović Nataša , Nietosvaara Vesa , Smiljanić Ivan
Published: March 2023

Recent surveys show that training in satellite meteorology in Europe is needed the most for: 1) better use of the existing and new products as well as being prepared for the future products from MTG and EPS-SG satellite data; 2)  forecasting and nowcasting of extreme and/or hazardous weather. These include the monitoring of convective environments and wider nowcasting applications and training on the operational use of integrated data sources, i.e. satellite data and other types of data and information. EUMETSAT, together with partners, is offering a wide range of training activities to answer these needs.  Target audience of the forecaster trainings are operational meteorologists (general, aviation and marine weather forecasters), trainers that train forecasters, users in different application areas, product and application developers, researchers, university teachers and students within EUMETSAT Member States, and even in wider Europe and Central Asia, as well as Africa, Middle East and Latin America.  

In Europe, training takes place through regional networks: NOMEK, BALTIC+, SEEMET and DACH in coordination with EUMeTrain, including also partner organizations and consortia (e.g. NWC SAF). These trainings are focused on everyday challenges of the operational forecasters, with special emphasis on applications of satellite data and products. Severe Convective Storms Testbeds run by ESSL are hands-on courses where forecasters learn how to use satellite, radar and model data in real-time for forecasting convective development and associated threats. Testbeds for Aviation forecasters, run by FMI, cover the topics important for aviation, such as icing, turbulence etc., using satellite and other data in operational forecast environment. International Summer school of Remote Sensing is more focused on data processing and visualization, and it serves more experienced users with hands-on activities in satellite data discovery and utilization.

In wider Europe as well as in Africa, Middle East and beyond the training takes place in cooperation with the VLab Centres of Excellence within the region, and is tailored to the regional needs. 

The paper will present the entire range of EUMETSAT training activities.
Developing a tile drainage module for Cold Regions Hydrological Model: Lessons from a farm in Southern Ontario, Canada
Authors: Kompanizare Mazda , Costa Diogo , Macrae Merrin , Pomeroy John , Petrone Richard
Published: March 2023

Abstract. Systematic tile drainage is used extensively in agricultural lands to remove excess water and improve crop growth; however, tiles can also transfer nutrients from farmlands to downstream surface water bodies, leading to water quality problems. There is a need to simulate the hydrological behaviour of tile drains to understand the impacts of climate or land management change on agricultural runoff. The Cold Regions Hydrological Model (CRHM) is a physically based, modular modelling system that enables the creation of comprehensive models appropriate for cold regions by including a full suite of winter, spring, and summer season processes and coupling these together via mass and energy balances. A new tile drainage module was developed for CRHM to account for this process in tile-drained landscapes that are increasingly common in cultivated basins of the Great Lakes and northern Prairies regions of North America. A robust multi-variable, multi-criteria model performance evaluation strategy was deployed to examine the ability of the module with CRHM to capture tile discharge under both winter and summer conditions. Results showed that soil moisture is largely regulated by tile flow and lateral flow from adjacent fields. The explicit representation of capillary rise for moisture interactions between the rooting zone and groundwater greatly improved model simulations, demonstrating its significance in the hydrology of tile drains in loam soils. Water level patterns revealed a bimodal behaviour that depended on the positioning of the capillary fringe relative to the tile. A novel aspect of this module is the use of field capacity and its corresponding pressure head to provide an estimate of drainable water and thickness of the capillary fringe, rather than a detailed soil retention curve that may not always be available. Understanding the bimodal nature of soil water levels provides better insight into the significance of dynamic water exchange between soil layers below drains to improve tile drainage representation in models.
Revisiting Early Jurassic Biscutaceae:Similiscutum giganteumsp. nov.
Authors: Mailliot Samuel , Mattioli Emanuela , Chaumeil Rodríguez Micaela , Pittet Bernard
Published: March 2023

Abstract. A large, broadly elliptical coccolith of the genus Similiscutum (Biscutaceae) was observed in sediments dated from the Lower Jurassic (upper Pliensbachian to Toarcian) coming from different localities of western Tethys, namely Portugal (Lusitanian Basin), France (Causses and Paris basins) and Spain (Subbetic area). This form is quite easy to find in the Toarcian GSSP (Global Stratotype Section and Point) of Peniche (Portugal), where the holotype has been described. More than 100 specimens of Similiscutum were digitally captured using a CCD camera, including this large form and two other related species, Similiscutum finchii and Similiscutum novum. The length and width of the coccoliths and the length and width of their central area were measured, and biometric analyses were performed. Results show that this large morphotype of Similiscutum is well characterized and easily differentiable by its size and morphology from the species S. finchii and S. novum, which are characterized by a similar extinction pattern in optical-microscope crossed polars . On the basis of combined differences in size and in central-area shape and structure, Similiscutum giganteum sp. nov. is introduced here.

Multi-station automatic classification of seismic signatures from the Lascar volcano database
Authors: Salazar Pablo , Yupanqui Franz , Meneses Claudio , Layana Susana , Yáñez Gonzalo
Published: March 2023

Abstract. This study was aimed to build a multi-station automatic classification system for volcanic seismic signatures such as hybrid, long period, tremor, tectonic, and volcano–tectonic events. This system was based on a probabilistic model made using transfer learning, which has, as the main tool, a pre-trained convolutional network named AlexNet. We designed five experiments using different datasets with data that were real, synthetic, two different combinations of these (combined 1 and combined 2), and a balanced subset without synthetic data. The experiment presented the highest scores when a process of data augmentation was introduced into processing sequence. Thus, the lack of real data in some classes (imbalance) dramatically affected the quality of the results, because the learning step (training) was overfitted to the more numerous classes. To test the model stability with variable inputs, we implemented a k-fold cross-validation procedure. Under this approach, the results reached high predictive performance, considering that only the percentage of recognition of the tectonic events (TC) class was partially affected. The results obtained showed the performance of the probabilistic model, reaching high scores over different test datasets. The most valuable benefit of using this technique was that the use of volcano seismic signals from multiple stations provided a more generalizable model which, in the near future, can be extended to multi-volcano database systems. The impact of this work is significant in the evaluation of hazard and risk by monitoring the dynamic evolution of volcanic centers, which is crucial for understanding the stages in a volcano’s eruptive cycle.
Wetting and drying cycles, organic amendments, and gypsum play a key role in structure formation and stability of sodic Vertisols
Authors: Niaz Sara , Wehr J. Bernhard , Dalal Ram C. , Kopittke Peter M. , Menzies Neal W.
Published: March 2023

Abstract. In the natural environment, soils undergo wetting and drying (WD) cycles due
to precipitation and evapotranspiration. The WD cycles have a profound
impact on soil physical, chemical, and biological properties and drive the
development of structure in soils. Degraded soils are often lacking
structure, and the effect of organic amendments and WD cycles on structure
formation of these soils is poorly understood. The aim of this study was to
evaluate the role of biotic and abiotic factors on aggregate formation and
stabilization of sodic soils after the addition of gypsum and organic
amendments (feedlot manure, chicken manure, lucerne pallets, and anionic
poly acrylamide). Amended soils were incubated at 25 ∘C over four
WD cycles, with assessment of soil microbial respiration, electrical
conductivity, pH, sodium adsorption ratio (SAR), aggregate stability in
water (ASWAT), aggregate size distribution, and mean weight diameter. Our
results demonstrate that WD cycles can improve aggregate stability after the
addition of amendments in sodic Vertisols, but this process depends on the
type of organic amendment. Lucerne pellets resulted in highest soil
microbial respiration, proportions of large macroaggregates (>2000 µm), and mean weight diameter. In contrast, dispersion was
significantly reduced when soils were treated with chicken manure, whilst
anionic polyacrylamide only had a transient effect on aggregate stability.
When these organic amendments were applied together with gypsum, the
stability of aggregates was further enhanced, and dispersion became
negligible after the second WD cycle. The formation and stability of small
macroaggregates (2000–250 µm) was less dependent on the type of
organic amendments and more dependent on WD cycles as the proportion of
small macroaggregates also increased in control soils after four WD cycles,
highlighting the role of WD cycles as one of the key factors that improves
aggregation and stability of sodic Vertisols.
A framework for time-dependent Ice Sheet Uncertainty Quantification, applied to three West Antarctic ice streams
Authors: Recinos Beatriz , Goldberg Daniel , Maddison James R. , Todd Joe
Published: March 2023

Abstract. Ice sheet models are the main tool to generate forecasts of ice sheet mass loss; a significant contributor to sea-level rise, thus knowing the likelihood of such projections is of critical societal importance. However, to capture the complete range of possible projections of mass loss, ice sheet models need efficient methods to quantify the forecast uncertainty. Uncertainties originate from the model structure, from the climate and ocean forcing used to run the model and from model calibration. Here we quantify the latter, applying an error propagation framework to a realistic setting in West Antarctica. As in many other ice-sheet modelling studies we use a control method to calibrate grid-scale flow parameters (parameters describing the basal drag and ice stiffness) with remotely-sensed observations. Yet our framework augments the control method with a Hessian-based Bayesian approach that estimates the posterior covariance of the inverted parameters. This enables us to quantify the impact of the calibration uncertainty on forecasts of sea-level rise contribution or volume above flotation (VAF), due to the choice of different regularisation strengths (prior strengths), sliding laws and velocity inputs. We find that by choosing different satellite ice velocity products our model leads to different estimates of VAF after 40 years. We use this difference in model output to quantify the variance that projections of VAF are expected to have after 40 years and identify prior strengths that can reproduce that variability. We demonstrate that if we use prior strengths suggested by L-curve analysis, as is typically done in ice-sheet calibration studies, our uncertainty quantification is not able to reproduce that same variability. The regularisation suggested by the L-curves is too strong and thus propagating the observational error through to VAF uncertainties under this choice of prior leads to errors that are smaller than those suggested by our 2-member “sample” of observed velocity fields. Additionally, our experiments suggest that large amounts of data points may be redundant, with implications for the error propagation of VAF.

Prescibable mHealth using built-in device sensors: A mixed methods exploration of a respiratory therapy app for smartphones
Authors:   , Baxter Clarence
Published: March 2023

Clinicians are cautious about embracing prescription of health and well-being (i.e., mHealth) smartphone apps to patients, citing a lack of evidence regarding safety, reliability and clinical validity as barriers to wider adoption. This doctoral thesis presents an exploration of a new smartphone mHealth app (QUT Inspire) which virtualises a longstanding respiratory therapy technique called Incentive Spirometry (i.e., ISy); this new app detects inspired breath sounds using the built-in phone microphone and displays responsive animated on-screen graphics to encourage engagement, effort and persistence with virtualised ISy therapy.
Zero-history blockchains and zero-knowledge contracts for the post quantum era
Authors:   , Alupotha Jayamine
Published: March 2023

We are living in the pre-quantum era, still wondering whether quantum computing is possible, akin to humankind 50 years ago who had no idea those room-filling computers could be shrunk into palm-sized mobile phones. In the interim, we must prepare our information systems, including decentralized blockchains, to withstand quantum adversaries. Alas, post-quantum cryptography comes with vastly more onerous space and time requirements, to the detriment of scalability. This work proposes new theories and protocols to achieve scalable blockchains that support privacy-preserving smart contracts, not only with classical security but also with post-quantum security.
Topic-based co-training and query-based semantic feature for text classification
Authors:   , Shayegh Boroujeni Parvaneh
Published: March 2023

The existing co-training methods for text classification have overlooked the relevance of their classifiers with the topic of their documents. In addition, they have overlooked the semantic relevance of the most important parts of the documents with the classes. This thesis addresses these gaps by developing a framework for text classification consisting of a topic-based co-training with fused-feature convolutional neural network and integrated semantic features by question-answering. Implementation results of this framework on popular datasets show that it outperforms the existing baseline methods including variants of support vector machine, naïve Bayes, decision tree, K-nearest neighbors, convolutional and recurrent neural networks.

: Heart failure is a multi-faceted and life threating syndrome. In the management of CHF, a gap between Guideline-Directed Medical Therapy (GDMT) and actual practice has been reported. An increase in the prevalence of co-morbid conditions and risk factors, such as increased body mass index (BMI), metabolic syndrome, and cigarette smoking may be some of the reasons behind the increased prevalence of HF
Reflections on the concept of respect for the rights and freedoms of the person in the special investigation activity
Authors: Glavan Boris
Published: March 2023

The paper is dedicated to elucidating one of the most controversial issues of the special investigation activity related to the content of the concept of respect for the rights and freedoms of the person. The uncertainty that initiated this research starts from the trivial question: what should be understood by respecting the rights and freedoms of the person, fundamental principle of the special investigation activity, given that, on the one hand, the measures specific to this type of activity, by their nature, do they interfere with the rights and freedoms of the person, and on the other hand, does the national legislature distinguish between the notion of respect for the rights and freedoms of the person and that of the authorized restriction of those rights and freedoms? At the same time, the factual data obtained through the special activity of investigations fall into the disgrace of the law if the rights and freedoms of the person are not respected. All these ambiguities together are the subject of this study.
Theoretical-conceptual aspects regarding the entitlement of the legal field concerned by the protection of environmental factors
Authors: Creţu Andrian
Published: March 2023

Accurate knowledge of the scope of a field or branches of law is an indispensable condition for the evolution of any branch of the legal system. This is also the case with environmental law. Despite the various debates on the correct name of the branch concerned with the protection of environmental factors, launched in the doctrinal space since its inception, today more and more specialists in the field use the phrase “environmental law” when referring to legal relations established during protection environmental protection, development, conservation and rational use of all environmental components, including anthropogenic ones. However, there is currently some controversy regarding the certainty of the legal segment of concern for the field of environmental law, often being confused with that of ecology science, superimposed even at the level of scientific and didactic approach. For this reason, we decided to end the discussions that further complicate matters, trying to show that ecology and the environment, respectively, environmental law are distinct areas, although very close, correlated and coexisting in the legal system.

A Study on Hair Design Works Using the Formative Elements of Frank Gehry’s Architecture
Authors: Lee Myoung-Joo , Seo Sun-Min
Published: March 2023

This research is to provide a new perspective and direction on original hair design by analyzing the formability of Frank Gehry architecture and visualizing the characteristics and producing three creative hair design works. The conclusions of this research are as follows. First, through domestic and international prior research and literature research, the formative characteristics of Frank Gehry's architecture are three types: organic structure, distortion and asymmetry, dismantling and overlapping. Second, after examining Frank Gehry's deconstructive architectural characteristics, We selected five representative buildings. Third, We made three hair design works by using various expression techniques to clearly reveal the formative characteristics of Frank Gehry's architecture. The characteristics and production process of the work were organized along with photos. Based on these hair design works, conclusions can be drawn as follows. First, The atypical form beauty in Frank Gehry architecture can be motive of rich hair design. Second, The expression of hair design can be expanded by providing formative features such as organic structure, distortion and asymmetry, dismantling and overlapping as morphological elements of hair design. Third, The materials and colors used in Frank Gehry architecture could be applied not only to hair design but also to beauty fields that can give artistic value such as makeup and nails. Based on the connection between architecture and hair, the Frank Gehry's morphological features can be reinterpreted as hair design and such creative designs can be presented beyond limitations through various techniques and approaches.

Published: March 2023

This study aims to investigate the anti-acne efficacy of the plant extract complex (PEC) consisting of Camellia sinensis L. leaf and Castanea crenata bur extract in vitro. The effect of PEC on anti-acne target including sebum production, Cutibacterium acnes (C. acnes)-induced inflammation, 5-alpha reductase activity and free radical scavenging activity was observed. The level of lipid production was measured through nile red staining in sebocytes to confirm the effectiveness of inhibiting sebum production, and C. acnes cultured medium (C. acnes CM) were treated on HEK293-hTLR2 cells to observe TLR2 activity. In addition, regulation of 5-alpha reductase activity was confirmed using rat liver microsomes, and antioxidant capacity was measured by DPPH assay. As a result, PEC showed the inhibitory effect on sebum production up to 59.02±5.13% at 100 μg/mL and the C. acnes CM with PEC treated group dramatically inhibited the TLR2 activity as much as the control level. At 100 μg/mL of the PEC, the activity of 5-alpha reductase enzyme activity was suppressed by about 20% compared to the group treated with rat microsomes, and the radical scavenging capacity was measured at 86.83±10.19. These results suggest that PEC, a complex extract of Camellia sinensis L. leaf and Castanea crenata bur, can be used as natural cosmetic raw materials that can relieve acne through inhibition of excessive sebum production, reduction of 5-alpha reductase activity, anti-inflammatory, and antioxidant properties.
The Impact of the Consumer-Brand Interaction and Relationship on Motivation to Buy Cosmetics in Social Media -Based on Cognitive Age-
Authors: Kim In-Ok , Kwon Oh-Hyeok
Published: March 2023

This study conducted a survey method to analyze the influence of the consumer-brand interaction and the consumer-brand relationship on the motivation to buy cosmetics based on the cognitive age of men and women in their teens and 50s with social media accounts. As a result, as a result of classifying cognitive age based on the actual age of the subjects and their perceived age, 'same cognitive group (61.2%)' > 'lower cognitive group (24.0%)' > 'higher cognitive group (14.8%)'. In the three groups, the consumer-brand interaction and the consumer-brand relationship showed a significant positive relationship, and the consumer-brand interaction and the motivation to buy cosmetics also showed a meaningful positive relationship. In addition, the consumer-brand relationship and the motivation to buy cosmetics also showed a significant positive relationship. Accordingly, the conclusion of this study was that the consumer-brand interaction and the consumer-brand relationship by subjective age group had a positive effect on the cosmetics purchase motive. As this study empirically analyzes the influence of cognitive age on cosmetics brand marketing in social media, it is considered to be a practical implication for establishing basic data and cosmetics sales strategies that can be used for marketing.
The Effects of Consumer Information Confusion and Choice Confusion on Purchasing-Related Behavior of Adult Men in Their 20s and 30s When Purchasing Basic Cosmetics in a Multi-Channel Environment
Authors: Kim Eun-Ju , Kim Ju-Youn
Published: March 2023

The purpose of this study is to understand the effects of consumer information confusion and choice confusion perceived by adult men in their 20s-30s on purchase-related behaviors for the purchase of basic skincare cosmetics in multichannel environment. The research subjects were adult men in their 20s-30s who had experiences in on/offline information search for the purchase of basic skincare cosmetics in Seoul, Gyeonggi, and Incheon region. From June 15 to July 15, 2022, an online survey using NAVER Form was conducted. Total 300 questionnaires were distributed and then 295 questionnaires were utilized for the final analysis after excluding five questionnaires with insincere responses. Using the SPSS WIN 21.0 Program for data analysis, this study conducted the frequency analysis, descriptive statistics analysis, factor analysis, correlation analysis, and multiple regression analysis. In the results of this study, when the information confusion got higher due to the overloaded information about basic skincare cosmetics on/offline, the behavior of delaying the purchase of basic skincare products was highly shown in adult men in their 20s-30s. Also, in case of the purchase of basic skincare cosmetics, there are many similar basic skincare cosmetic products in on/offline shops. When the confusion about the choice of basic skincare cosmetics suitable for one’s own skin type was higher, the behavior of delaying the purchase decision-making of basic skincare cosmetics was highly shown in adult men in their 20s-30s. In the results of this study, the adult men in their 20s-30s are facing much confusion about cosmetic information search and choice due to numerous cosmetic information on/offline, and also delaying their purchase for a moment as it is not directly connected to the purchase of cosmetics. This shows that the adult men in their 20s-30s are facing much confusion in the circumstance of choosing their basic skincare cosmetics among massive, exaggerated, and similar information about cosmetics in the information environment.

Hybris Syndrome as a Danger of Power
Authors: ȘENDREA Mariana
Published: March 2023

In the specialized literature, the Hybris Syndrome and the paradox of power are described as characteristics of authoritarian power, which have negative repercussions on society or the organization. Being, in fact, imminent characteristics of any power, within the authoritarian leadership style, it manifests itself most intensely. The phenomena of power paradox and Hubris Syndrome are important for the study of authoritarian thinking and behaviour, as they allow us to understand the mental and attitudinal factors that influence the formation of authoritarian leadership styles. The Hybris Syndrome is an occupational hazard that affects all leaders, whether they are managers, soldiers, politicians or scientists. The feeling of omnipotence and impunity can occur in leaders of any level and in any field of activity, but the risk increases with the rise in the hierarchical ladder and with the increase in the duration of the person's position.
Conceptual Analysis of the Term Diaspora through the Prism of the Contribution to the Economic Development of the Countries of Origin
Authors: CHIRVAS Cristina
Published: March 2023

The process of diaspora formation is usually conditioned by migration processes and the creation of migrant communities abroad is one of the effects of migration that bring with it a series of advantages for the countries of origin. Diaspora represents an active power, involved in almost all fields of activity of a society, therefore, in the specialized literature, the term itself is treated differently, depending on the field of study that addresses it. However, how can diaspora be defined, how can its size be assessed, how is this term different from migration, how the interest in the study of diaspora has evolved and what are the economic ramifications of diaspora actions for the countries of origin, are just some of the aspects that we propose to address during the research.
Approach of Some Economic and Mathematical Models of Production and Transportation Problems with Environmental Pollution Restrictions
Authors: BLANUȚA Ștefan , GODONOAGĂ Anatol
Published: March 2023

The paper addresses some decisionmaking processes in the economic areas of production and transport, focused on the optimization, in various aspects, of these processes. A special emphasis is given to capitalizing on optimal decisions, respecting traditional conditions and special restrictions imposed by the pollution phenomenon. Pollution is the consequence of economic activities in the respective fields. In most economic and mathematical models, the pollution functions define constraints, which can essentially reduce, compared to classical situations, the set of admissible solutions. For certain situations, constructive numerical algorithms are proposed, which could effectively and in real time solve the problems in question.

Published: March 2023

Food availability is one of the important pillars of food security. It is essential to ensure food availability in the world to avoid starvation. The key concern of the present study is to integrate the fluctuations in the growth rate of the population and important food crop production using time series data from 1950-2021. Semi-log compound growth rate models are applied for the projection, Cuddy-Della and Valle instability index are used for the stability analysis, and decomposition analysis models are applied to determine the contribution of factors toward production. Semi log compound growth rate model indicates that the population of Pakistan is increasing rapidly, while the contribution of productivity and area of all food crops are not enough to meet food sustainability. The growth rate in the area and production of Wheat, Rice, and Maize are positive, while it is negative for Sorghum (jawar), Millet (bajra), and Barley. For areas, a low degree of instability is prevailing for Wheat, Rice, Maize, Sorghum (jawar), and population, while the medium is for Millet (bajra) and Barley. For yield, the degree of instability is low for all food crops except Maize, which lies in the medium instability index. Semi log compound growth rate model was found best fitted for area and productivity for all food crops, while for the production side, it is found best for Wheat, Rice, and Maize and bit fit for Sorghum (jawar), Millet (bajra) and Barley. Decomposition analysis model predicted that crop productivity is a major concern to attain food security in Pakistan.
