Authors:   Delhi Technological University Department of Applied Mathematics, India, MISHRA NAV SHAKTI , DEO NAOKANT ,   Delhi Technological University Department of Applied Mathematics, India
Published: March 2024

The present paper deals with the Durrmeyer construction of operators based on a class of orthogonal polynomials called Apostol-Genocchi polynomials. For the proposed operators, we ﬁrst establish a global approximation result followed by its convergence estimate in terms of usual, r-th and weighted modulus of continuity. We further study the asymptotic type results such as the Voronovskaya theorem and quantitative Voronovskaya theorem. Moreover, we estimate the rate of pointwise convergence of the proposed operators for functions of bounded variation deﬁned on the interval (0,∞). Finally, the results are validated through graphical representations and an absolute error table.

In the present paper, we have introduced a new class of preinvexity namely hyperbolic type harmonic preinvex functions and to support this new deﬁnition, some of its algebraic properties are elaborated. By using this new class of preinvexity, we have established a few Hermite-Hadamard type integral inequalities. Some novel reﬁnements of Hemite-Hadamard type inequalities for hyperbolic type harmonic preinvex functions are presented as well. Finally, the Riemann-Liouville fractional version of the Hermite-Hadamard Inequality is established.

The primary aim of this research endeavor is to innovate a viable and user-friendly UV spectroscopic approach for quantifying formoterol and beclomethasone within metered dose inhalers (MDIs). These formulations, amalgamating Beclomethasone Dipropionate (BDP) and Formoterol Fumarate (FF), are extensively employed in managing bronchial asthma and chronic obstructive pulmonary diseases. Although analytical techniques already exist for assessing formoterol and beclomethasone in combination dry powder inhalers, this study concentrates on devising and validating a UV spectrophotometric method for simultaneously quantifying formoterol fumarate and Anhydrous Beclomethasone Dipropionate in Pressurized Metered Dose Inhalers (pMDIs). The estimation is performed at a wavelength of 240 nm for Beclomethasone Dipropionate and 216 nm for Formoterol Fumarate. Both drugs demonstrate satisfactory linearity within the concentration range of 10-30 μg/ml for BDP and 0.3 to 0.9 μg/ml for FF at wavelengths of 240 nm (r^2=0.999) and 216 nm (r^2=0.999), respectively. The Beer-Lambert law is adhered to within the concentration range of 10-30 μg/ml for BDP and 0.3-0.9 μg/ml for FF. The proposed methods are subjected to validation following ICH guidelines to assess accuracy, method precision, specificity, among other parameters. As a result, the proposed method can be effectively employed for the simultaneous determination of Beclomethasone Dipropionate and Formoterol Fumarate in routine analytical applications, offering a rapid and reliable solution for pharmaceutical analysis in the field.

Published: March 2024

In Romania, the issue of economic inequalities and regional convergence is one of the current important topics on which the attention of economic specialists and the decision-making factors is focused. In the actual context, the regional policy in Romania is implemented at regional level, the regions being formed by counties that have voluntarily associated on the basis of a convention signed by the representatives of the County Councils, respectively of the General Council of Bucharest. After the year 2000, the development regions faced two major crises: the global financial crisis (2008-2009) and the one caused by the COVID-19 pandemic (2020-2021). Both crises have caused important effects at regional level and both have been supported by a number of territorial strategies and policies, to which there was added the cohesion and regional development policy financed by the EU Structural Funds. The paper is based on the analysis of the differences between the regions of Romania, in the period 2008-2022, during the COVID-19 pandemic, by highlighting the differences between the dynamics of certain indicators, of the analysis of the GINI coefficients for measuring inequalities, trying to answer the question which of the two crises, financial or health, affected the level of territorial inequalities more and what was the evolution of the regions of Romania in these two sub-periods. Regarding the financial crisis versus the pandemic one, in the majority of the indicators, it was shown that the values of the Gini coefficients in the 2020-2022 were higher than the ones in 2008-2010 and also after the COVID-19 crisis the tendency of increased disparities was maintained. The only domains that were least affected by the pandemic were demography (rural population), transportation infrastructure and economic potential (companies with 10-49 employees).

The main objective of this paper is to present the relationship between poverty, unemployment and education reaching the occupational structure of poverty. In order to understand the interdependence of the three concepts, I have started with the review of the definitions given by renowned specialists in the study of poverty. Afterwards, I have analysed the causes, determinants and types of poverty. Subsequently, I have brought in the foreground the statistical data regarding the Romanian population in the period between 2018 and 2021, which reflect the extent to which the citizens of our country are exposed and especially the children of the scourge of poverty. I wanted to highlight the interdependence between the level of education, unemployment and poverty rate. I have reviewed the ongoing plans and strategies undertaken by the Romanian Government having as objective the eradication of poverty by ensuring a quality education, which is considered an effective instrument for breaking the vicious circle of poverty.

Published: March 2024

Freight transport is certainly the most important branch of transport and certainly one of the most important branches of the economy in general. There is a close link between transport and the evolution and development if mankind, which is why the field of transport has always been of great interest and has undergone a multitude of changes throughout the history. The development of the freight transport sector varies from country to country, with significant differences from one country to another. Freight transport in Romania has not been an area of great interest, and this lack of interest is reflected in the lack of investment needed to operate properly and to make this area attractive and economically efficient.

Combating poverty represents one of the challenges of the modern economy and Europe’s geopolitical situation contributes to worsening this problem. Economic growth and employment rate are determinants of the level of poverty in a society. Unemployment and its consequences are widely approached both in economic literature and in sociology and psychology. In the first part of the paper, we carried out a conceptual presentation of the economic and social consequences of unemployment at the national, individual, and family level. In the second part, starting from Okun’s law, we made an analysis of the relationship between the gross domestic product and unemployment rate for the period from 2005-2022 in Romania. In order to carry out the research, we used a series of statistical data regarding the unemployment rate available in the Monthly Bulletins of the National Bank of Romania (NBR) and data on GDP available on the website of the National Institute of Statistics of Romania (NIS). We worked with data regarding the situation in Romania from the first quarter of 2005 – fourth quarter of 2022. The conclusions of the paper converge towards the idea that unemployment is, nowadays, an increasingly complex phenomenon, being generated by a multitude of factors and which, in turn, determine multi-level direct and indirect consequences.

The last three years were characterized by a climate of drastic change due to a cumulus of disturbances and crises, namely the COVID-19 pandemic, inflation, energy crisis, military conflicts, banking fragilities, populism, disinformation, and the idea of deglobalization. These types of events may be interpretated either as antecedents of new and complex categories of risks or as stimulus for certain risks that have long been ignored. One central focus for worldwide policymakers is presently the country risk with all its components (sovereign risk, political risk, market risk, or systemic risk). Furthermore, due to the increase in public and private debt, the risks to which economies are exposed have multiplied. Is this the end of an era or just a temporary disequilibrium? This is one of the key questions among economists, academics, and policy makers around the world. The main purpose of this research is to analyse whether the Russian invasion of Ukraine negatively impacted the country risk of countries situated in the geographical proximity of the conflict area (Romania, Bulgaria, Estonia, Hungary, Czechia, Latvia, Lithuania, Poland, and Slovakia), as well as to determine whether relevant macroeconomic indicators such as debt/GDP, GDP/capita, inflation, or trade openness were deteriorated due to the war. The findings of this research reveal that all the analysed macroeconomic indicators deteriorated as a consequence of the high degree of uncertainty concerning the future economic prospects of these countries, especially inflation and debt/GDP. The results also indicate that the country ratings of the investigated group of countries were severely impacted by the Russian invasion of Ukraine. Although data corresponding for year 2023 show a slight improvement, the existing uncertainty continues to generate a disruptive effect on the markets.
Understanding Dog Behavior through Visual and Auditory Sensing Using Machine Learning
Authors: Lin Amy , Eastburn Mark
Published: March 2024

This work aims to understand a dog’s behavior towards environmental stimuli. Different from previous works, we collect multi-modality data including both video and audio data observed from the dog’s egocentric perspective. We propose to model the association between a dog’s reaction and the visual and auditory stimuli perceived by the dog using machine learning, in particular through an extended Convolutional Neural Network (eCNN). The eCNN model takes colored images, Short Time Fourier Transform (STFT) of audio, and motion fields extracted from image sequences as input, and outputs a prediction of the dog’s reaction, classified as Sit, Stand, Walk, or Smell. Our proposed model achieves promising prediction results, with an average accuracy of 79.02% over all four classes. We also evaluate model performance by separately using one of image, audio, and motion information. Our results show that the dog responds strongly to low-frequency sounds and various color differences in its field of view. These research findings provide valuable insights to understanding animal behavior and intelligence as well as insights for building robotic companion dogs.

Published: March 2024

. The reactivity of various precursors in the reaction of magnesia spinel formation: periclase, corundum and the combustion product of xerogel from aluminum nitrate with citric acid was compared. It has been established that the product of combustion without annealing is X-ray amorphous, which suggested its high chemical activity. When used, X-ray phase analysis showed a lower content of initial reagents compared to a mixture of periclase and corundum. The effect of mechanical pretreatment of reagents on spinel yield was analyzed. An increased efficiency of joint mechanoactivation of periclase and corundum, as well as the replacement of periclase with a product of xerogel combustion, was established.

Published: March 2024

Abstract. Clouds in Antarctica are key elements that affect radiative forcing and thus Antarctic climate evolution. Although the vast majority of clouds are composed of ice crystals, a non-negligible fraction is constituted of supercooled liquid water (SLW, water held in liquid form below 0 °C). Numerical weather prediction models have a great difficulty to forecast SLW clouds over Antarctica favouring ice at the expense of liquid water, and therefore incorrectly estimating the cloud radiative forcing. Remote sensing observations of SLW clouds have been carried out for several years at Concordia station (75° S, 123° E, 3233 m above mean sea level), combining active LIDAR measurements (SLW cloud detection) and passive HAMSTRAD microwave measurements (liquid water path, LWP). The present project aimed at in situ observations of SLW clouds using sondes developed by the company Anasphere, specifically designed for SLW content (SLWC) measurements. These SLWC sondes were coupled to standard meteorological pressure-temperature-humidity sondes from the Vaisala Company and released under meteorological balloons. During the 2021–2022 summer campaign, 15 launches were made, of which 7 were scientifically exploitable. Above a height of 400 m above ground level, we found that the SLWC sondes detected SLW clouds in a vertical range consistent with LIDAR observations. In nominal operation, the LWP values obtained either by HAMSTRAD or vertically-integrated from the SLWC sonde profiles were consistent in spite of their low values (< 10 g m-2). On some occasions far from nominal operation (surface fog, low vertical ascent of the balloon), the LWPs from the SLWC sonde were overestimated by a factor of 5–10 compared to the HAMSTRAD values. In general, the SLW clouds were observed in a layer close to saturation (U > 80 %) or saturated (U ~100–105 %) just below or at the lowermost part of the entrainment zone or capping inversion zone which exists at the top of the Planetary Boundary Layer and is characterized by an inflection point in the potential temperature vertical profiles. Our results are consistent with the theoretical view that SLW clouds form and pertain at the top of the Planetary Boundary Layer.
Planktonic foraminiferal assemblages as tracers of paleoceanographic changes within the Northern Benguela current system since the Early Pleistocene
Authors: Del Gaudio Arianna Valentina , Avery Aaron , Auer Gerald , Piller Werner Erwin , Kurz Walter
Published: March 2024

Abstract. The Benguela Upwelling System (BUS), located in the southeastern Atlantic Ocean, represents one of the world’s most productive regions. This system is delimited to the south by the Agulhas retroflection region. The northern boundary of the BUS is, instead, represented by the Angola Benguela Front (ABF), which is a thermal feature separating warm waters of the Angola Basin (including the South Atlantic Central Waters; SACW) from the cooler Benguela Oceanic Current (BOC). We performed statistical analyses on planktonic foraminiferal assemblages in 94 samples from Holes U1575A and U1576A, cored during International Ocean Discovery Program (IODP) Expedition 391. Drilled sites are located along the Tristan-Gough-Walvis Ridge (TGW) seamount track in the northern sector of the BUS (offshore the Namibian continental margin). The analyzed stratigraphic intervals span the Early-Late Pleistocene, marked by the Early-Middle Pleistocene Transition (EMPT; 1.40–0.40 Myr), during which important glacial-interglacial sea surface temperature (SST) variabilities occurred. This work provides novel insights on the local paleoceanographic evolution of the northern BUS and associated thermocline variability based on the ecological significance of the foraminiferal assemblages. Specifically, variations in the assemblage content allowed to characterize the different water masses (BOC, SACW, Agulhas waters) and reconstruct their interactions during the Quaternary. The interplay of the previously mentioned water masses induced perturbations in the BUS (ABF latitudinal shifts and input of tropical waters from the Agulhas retroflection region). Furthermore, we investigated the possible link between changes in the paleoceanographic conditions and climatic events (e.g., Benguela Niño/Niña-like phases and deglaciation stages) recorded since the EMPT.

Published: March 2024

Abstract. The RADIX (Rapid Access Drilling and Ice eXtraction) optical dust logger is part of the exploratory drilling system developed at the University of Bern. It was previously untested because no RADIX borehole reached to the depth of the required bubble-free ice. In June 2023, we tested the logger with an adapter for the large EastGRIP (East Greenland Ice-core Project) deep borehole. An excellent dust record was obtained for the Bølling-Allerød-Younger Dryas-Early Holocene period. The light scattered by the dust in the ice around the borehole was slightly higher than the detection range of the logger, requiring a reduction in the sensitivity for future deployments.
Improve iLOVECLIM (version 1.1) with a multi-layer snow model: surface mass balance evolution during the Last Interglacial
Authors: Hoang Thi-Khanh-Dieu , Quiquet Aurélien , Dumas Christophe , Born Andreas , Roche Didier M.
Published: March 2024

Abstract. During the Quaternary, ice sheets experienced several retreat-advanced cycles, strongly influencing climate patterns. In order to properly simulate these phenomena, it is preferable to use physics-based models instead of parameterizations to estimate surface mass balance (SMB) which has a strong influence on the ice sheet evolution. To further investigate the potential of these SMB models, this work evaluates BESSI (BErgen Snow Simulator), a multi-layer snow model with high computational efficiency, as an alternative to providing SMB for paleo studies. First, we validate the snow model using the regional climate model MAR (Modèle Atmosphérique Régional) as forcing and reference for the present-day climate over Greenland and Antarctic Ice Sheets. The evolution of SMB over the Last Interglacial period (LIG) (130–116 kaBP) is computed by forcing BESSI with transient climate forcing obtained from an Earth system model iLOVECLIM for both ice sheets. For present-day climate conditions, BESSI exhibits good performance compared to MAR despite a much simpler model set-up. The model also captures well the variation of SMB and its components during the LIG. Compared to the current simple melt estimation scheme of iLOVECLIM (ITM), BESSI is able to capture different SMB patterns for two particular ice sheet climate conditions thanks to its higher physical constraints while ITM displays a strong sensitivity to its parameters and input fields (temperature). The findings suggest that BESSI can provide more reliable SMB estimations for the iLOVECLIM framework to improve the model simulations of the ice sheet evolution and interactions with climate.
The effect of ice rheology on shelf edge bending
Authors: Buck W. Roger
Published: March 2024

Abstract. The distribution of water pressure on the vertical front of an ice shelf has been shown to cause downward bending of the edge if the ice has vertically uniform viscosity. Satellite lidar observations show upward bending of shelf edges for some areas with cold surface temperatures. A simple analysis shows that upward bending of shelf edges can result from vertical variations in ice viscosity. Such variations are an expected consequence of the temperature dependence of ice viscosity and temperature variations through a shelf. Resultant vertical variations in horizontal stress produce an internal bending moment that can counter the bending moment due to the shelf-front water pressure. Assuming a linear profile of ice temperature with depth and an Arrhenius relation between temperature and strain rate allows derivation of an analytic expression for internal bending moments. The effect of a power-law relation between stress difference and strain rate is also included analytically. The key ice rheologic parameter affecting shelf edge bending is the ratio of the activation energy, Q, and the power-law exponent, n. For cold ice surface temperatures and large values of Q/n, upward bending is expected, while for warm surface temperatures and small values of Q/n downward bending is expected. The amplitude of bending should scale with the ice shelf thickness to the power 3/2 and this is approximately consistent with a recent analysis of shelf edge deflections for the Ross Ice Shelf.

The mathematical apparatus of Nicolaus Copernicus's "De revolutionibus orbium coelestium" and its reception in secondary school education on the Polish territories from the 16th to the 21st century
Authors: Karpińska Karolina
Published: March 2024

W artykule dokonano analizy treści zawartych w rozdziałach XII, XIII i XIV pierwszej księgi „De revolutionibus orbium coelestium” Mikołaja Kopernika. Rozdziały te zawierają materiał trygonometryczny, na którym astronom oparł wszelkie rozważania dotyczące heliocentryzmu. W rozdziale XII zbudował tablice „cięciw w kole”, które dzisiaj nazwalibyśmy tablicami sinusów. W rozdziałach XIII i XIV zajął się rozwiązywaniem trójkątów płaskich i sferycznych. W niniejszym artykule ten aparat matematyczny został przeanalizowany ze współczesnego punktu widzenia, przy użyciu współczesnych oznaczeń i terminologii. Analizie została poddana recepcja matematyki Kopernika w nauczaniu szkolnym realizowanym na ziemiach polskich od XVI do XXI w.
The smile of fortune and the bitterness of fate. Alexander Sculteti
(c. 1485–1570), friend of Nicolaus Copernicus
Authors: Borawska Teresa
Published: March 2024

Urodzony ok. 1485 roku syn rajcy tczewskiego studiował najpierw w Krakowie (1503-1508), a następnie w Rzymie, gdzie zdobył dyplom doktora obojga praw. Dzięki swoim talentom oraz przynależności do „familii” kardynała Aleksandra Farnese (przyszłego papieża Pawła III) Sculteti uzyskał w 1514 roku kanonie w Dorpacie i w Hapsal, a w 1519 roku w Rewlu oraz we Fromborku. W obliczu reformacji Sculteti, dostrzegał konieczność reformy Kościoła, bronił praw Giesego, wyznaczonego przez schorowanego biskupa Maurycego Ferbera na swojego koadiutora. Naraził się wówczas biskupowi chełmińskiemu Janowi Dantyszkowi oraz sekretarzowi królewskiemu Stanisławowi Hozjuszowi. Oskarżony przez nich o złamanie celibatu oraz wyznawanie herezji został przez króla skazany na banicję, toteż jesienią 1540 roku wyjechał do Rzymu. Zaliczany był do kręgu zwolenników soboru trydenckiego i uczestniczył w jego otwarciu. Zmarł w 1570 roku Rzymie, a jego księgozbiór przeszedł na własność bractwa "S. Maria dell‵ Anima".

Gwangju ‘5·18 Road’ Branding Analysis Through the City Branding Mix Elements: Focusing on the OIPTCR Mix Elements
Authors:   Korean Association of Arts Management, Lee MuYong
Published: March 2024

This study started from the perspective that '5·18 Road' can play an important role in city branding in Gwangju. Based on the theoretical consideration of city branding strategy elements, the purpose of this study is to derive city branding mix elements and indicators, and apply them to systematically and comprehensively analyze the branding status of Gwangju 5·18 Road. The research contents include deriving the 'OIPTCR City Branding Mix Indicators' through the existing OIPTCR mix elements and city branding strategy elements research, arranging the process of promoting 5·18 Road, analyzing the current status of 5·18 Road branding, and deriving implications. The research method focused on literature research and content analysis, and case study applying empirical marketing and normative marketing methodology. As a result of the study, the 'OIPTCR City Branding Mix Indicators' (a total of 24 indicators, that is, 4 organization, 4 image, 5 product, 4 target, 4 channel, and 3 region), which are mix indicators for each element according to six elements of city branding mix (organization, image, product, target, channel, and region), was derived. As a result of applying and analyzing this to 5·18 Road, the project was promoted around a total of 18 indicators, and 6 indicators (1 organization, 2 image, 3 target) were found to have no project. The implications of this study are that it can contribute to the discussion of branding mix theory by deriving new city branding mix indicators, and that it can practically help revitalize the 5·18 Road business by theoretically, systematically, and comprehensively analyzing the current status of 5·18 Road branding.
