Discrete Gaussian for Differential Privacy
Authors: Canonne Clement , Kamath Gautam , Steinke Thomas
Published: August 2022

A key tool for building differentially private systems is adding Gaussian noise to the output of a function evaluated on a sensitive dataset. Unfortunately, using a continuous distribution presents several practical challenges. First and foremost, finite computers cannot exactly represent samples from continuous distributions, and previous work has demonstrated that seemingly innocuous numerical errors can entirely destroy privacy. Moreover, when the underlying data is itself discrete (e.g., population counts), adding continuous noise makes the result less interpretable.
With these shortcomings in mind, we introduce and analyze the discrete Gaussian in the context of differential privacy. Specifically, we theoretically and experimentally show that adding discrete Gaussian noise provides essentially the same privacy and accuracy guarantees as the addition of continuous Gaussian noise. We also present an simple and efficient algorithm for exact sampling from this distribution. This demonstrates its applicability for privately answering counting queries, or more generally, low-sensitivity integer-valued queries.

Authors: Khirallah Mustafa , Alkhomsan Asma
Published: July 2022

In this paper, we provided a new fourth-order optimal method. This method demands three functional evaluations, and according to Kung-Traub it is considered as one of the optimal methods with efficiency indicator I that reaches 1.587. Furthermore, we can extend its convergence to obtain a new sixth-order method where its efficiency indicator is 1.565. In this paper, we also discuss the convergence analysis of our new methods as it was established that the new methods have convergence orders four and six. Moreover, we will illustrate our study of the stability criterion of the new methods, and we will present the stability theorems along with some examples which prove that our methods are stable. Finally, we have discussed attraction basins for those suggestedmethods and compared them with methods that have the same order, and we have applied them for numerical examples to clarify the performance and efficiency of the proposed methods.

Authors: Alib Clarence , Magpantay Daryl M.
Published: July 2022

The interplay of groups and graphs has been a subject of interest by mathematics researchers nowadays. One particular instance is the identity graph of a group introduced by Kandasamy [5]. Moreover, the concept of a central graph of any graph is widely used by many graph theorists. The central graph of a graph G denoted by C(G) can be obtained by subdividing the edge of G exactly once and joining all the nonadjacent vertices of G in C(G). In this paper, we construct the central graph of the identity graph of finite cyclic group and investigate some of its graph properties.

Authors: Alomari Omar , Abudayah Mohammad , Ghanem Manal
Published: July 2022

A mixed graph D is a graph that can be obtained from a graph by orienting some of its edges. Let α be a primitive n th root of unity, then the α−Hermitian adjacency matrix of a mixed graph is defined to be the matrix Hα = [hrs] where hrs = α if rs is an arc in D, hrs = α if sr is an arc in D, hrs = 1 if sr is a digon in D and hrs = 0 otherwise. In this paper we study the cospectrality of the Hermitian adjacency matrix of a mixed graph.

Authors: Ibtihal.J.M  , Mohammad Ali J.
Published: July 2022

This research is defined a new neural network (NN) that depends upon a positive integer parameter using the multivariate square rational Bernstein polynomials. Some theorems for this network are proved, such as the pointwise and the uniform approximation theorems. Firstly, the absolute moment for a function that belongs to Lipschitz space is defined to estimate the order of the NN. Secondly, some numerical applications for this NN are given by taking two test functions. Finally, the numerical results for this network are compared with the classical neural networks (NNs). The results turn out that the new network is better than the classical one.

A Pegagogical Study of Geometric Relations between the Sums of Cubic Integer Numbers and the Sums of Square Integer Numbers with the Sums of Odd Numbers
Authors: Kobayashi Yukio
Published: July 2022

The geometric meaning of the sums of cubic and square numbers can be explained by expressing them as sums of consecutive odd numbers. By illustrating not only the equations but also simple diagrams, we can understand how these sums can be obtained. Geometrically viewing the relationship between series, rather than merely learning how to calculate them, helps studentsunderstand these series systematically. If natural numbers are expressed as sums of only 1, the sums of square numbers and of cubic numbers can be related to the multiplication of a vertical vector with a horizontal one whose components are all 1’s. This view is educational in showing that matrix multiplication is related to the calculation of series. The notion that concepts asdifferent as series and matrices are fundamentally and closely related is an important perspective in mathematics education.
Using the Sum of Triangular Numbers as the most Fundamental Number of Combinations Found using Heuristic Methods
Authors: Kobayashi Yukio
Published: July 2022

The same mathematical meaning can be expressed in many different ways. Students should deduce this and thus perceive that the different expressions have the same meaning. In this work, a pedagogical approach to the determination of various equations related to the sum of triangular numbers is presented as an example to show how students can deduce these different expressions and their meanings. The sum of triangular numbers is closely related to the sums of natural numbers, square numbers, and two consecutive numbers. These relationships can be found using a heuristic method in which the equations representing the sum of natural numbers are simply listed. Guiding students to discover the formula by themselves is important, rather than giving them the formula from the beginning and asking them to prove it. Triangular numbers are the fundamental numbers of combinations. The sum of $n$ consecutive triangular numbers is equal to $_{n+2}C_{3}$, as shown by combinatoric tree diagrams. The sum of the triangular numbers can be regarded as an extended version of the sum of the natural numbers.  The sum of square numbers is also related to the sum of triangular numbers, which is also easy to understand in terms of combinatorics. The combinatoric expression for the sum of triangular numbers can be extended to $\displaystyle \sum_{\ell=1}^{k-1}\ _{n-\ell}C_{k-1} =\ _{n}C_{k}$, which can be expressed as the sum of triangular numbers. This study provides an example of teaching material that broadens students’ view of a given equation by crossing different learning units such as combinatorics and algebra. The sum of triangular numbers discussed in this study is simply an example of developing the habit of considering various interpretations of the same formula, but even well known formulas can be utilized for this type of subject matter.
Molecular Dynamic (MD) Simulation and Modeling the Bio-molecular Structure of Human UDP glucose -6-dehydrogenase Isoform 1 (hUGDH) Related to Prostate Cancer
Authors: Adegoke Afeez Babatunde
Published: August 2022

Computational methods were used to investigate both the physical and chemical properties of UDP-glucose 6-dehydrogenase (hUGDH). Secondary structure analysis of the query model was done using the Self-Optimized Prediction method With Alignment (SOPMA), the secondary structure predictions comprise of 40.69% Alpha helixes (Hh), 17.61% Extended strand (Ee), 7.69% Beta turn (Tt) and 34.01% of Random coil (Cc) with aliphatic index of 90.00 and instability index of 33.26 which classify the protein model to be thermally stable irrespective of it environment. Comparative modeling was used to predict a reliable tertiary structure for hUGDH and the obtained 3-dimensional model was validated using DOPE score profile, Ramachandran plot, and the QMEAN Z-score. The DOPE score profile shows a high similarity between the model and the template as little or no disparity was found in the profile patterns. Ramachandran plot of the model also shows that 92.5% of the amino acid residues were found at the most favored regions which make it stereo-chemically stable. The QMEAN z-score of UDP-glucose 6-dehydrogenase was predicted to be -0.15. The superimposed structure of the model and the template also gave RMSD of 0.125. All this shows that the predicted model is of good quality. An RMSD and Rg run via molecular dynamics (MD) simulation equally shows that the protein model attained stability at around 10ns. Protein – Protein interaction (PPI) network was also generated for the model with a high confidence score from UDP-glucuronic acid decarboxylase 1 (UXS1) when interacted with the other twenty proteins. In addition, the docking studies of the model and 3PRJ receptors with two prostate cancer drugs i.e. Apalutamide and Darolutamide gave similar binding affinity ranging between 6.0kcal/mol – 8.0kcal/mol for the most favored binding of the two drugs. Hence, the model can serve as a molecular target for designing new inhibitors for prostate cancer
Effect of Infection With Scabies on The Adrenaline Hormone Of Patients With Chronic Diseases In Basra City/ Southern Iraq
Authors: Mnati Saeed F.
Published: August 2022

Scabies, a parasitic skin infestation by the burrowing “itch” mite Sarcoptes scabiei, causes significant health problems for children and adults worldwide. Crusted scabies is a particularly severe form of scabies in which mites multiply into the millions, causing extensive skin crusting. The symptoms and signs of scabies suggest host immunity to the scabies mite. The defense against stress is executed by the hypothalamic-pituitary-adrenal axis and the sympathetic-adrenal medullary system. Adrenal gland is a major effector organ of stress system. During stress, adrenal gland rapidly responds with increased secretion of glucocorticoids (GCs) and catecholamines into circulation, which hormones, in turn, affect metabolism, to provide acutely energy, vasculature to increase blood pressure, and the immune system to prevent it from extensive activation. . The current study examined (80) people, of whom (16) had negative control samples and (64) had scabies and had chronic diseases such as heart disease, diabetes, pressure, lung, liver, kidneys, ulcers, cancer, anemia and epilepsy, the current study recorded the highest levels of adrenaline using the associated immunosorbent assay technique With the enzyme (ELISA), which is (523 pg / ml) for patients suffering from chronic heart disease and infected with the scabies mite parasite and their number (14) out of (64) have other chronic diseases and their percentage was (21.88%) and the current study recorded the lowest levels of the hormone adrenaline. In patients with scabies and suffering from epilepsy at a rate (219 pg / ml) percentage (1.56%), which shows the hormone levels in patients with scabies and suffering from chronic diseases and comparing them with the control samples .

Authors: Abdullah Estabraq T.
Published: August 2022

In this paper, a simulation of the electrical performance for Pentacene-based top-contact bottom-gate (TCBG) Organic Field-Effect Transistors (OFET) model with Polymethyl methacrylate (PMMA) and silicon nitride (Si3N4) as gate dielectrics was studied. The effects of gate dielectrics thickness on the device performance were investigated. The thickness of the two gate dielectric materials was in the range of 100-200nm to maintain a large current density and stable performance. MATLAB simulation demonstrated for model simulation results in terms of output and transfer characteristics for drain current and the transconductance. The layer thickness of 200nm may result in gate leakage current points to the requirement of optimizing the thickness of different layers for better performance.

Published: August 2022

During the biomass densification can be recognized various technological variables and also material parameters which significantly influences the final solid biofuels (pellets, briquettes) quality. In this paper, we will present the research findings concerning relationships between technological and material variables during densification of cocoa husks. Cocoa husks, as an unused raw feedstock after chocolate production, is a typical product of food factory. The main goal of presented experimental research is to determine the effect of compression pressure and material particle size on final biofuels quality, and thus investigate the possibilities for densification of cocoa husks. Experimental research described in this paper was realized by single-axis densification, which was represented by experimental pressing stand. The effect of mentioned investigated variables on the final pellets density was determined. Mutual interactions of these variables on final pellets quality are showing the importance of mentioned variables during the densification process. Impact of raw material particle size on final biofuels quality was also proven by experimental research on semi-production pelleting plant. Research findings dealing with pelleting and briquetting possibilities are included.

Authors: Rahman Aqeel , Almallah Inass , Mousa Ahmed
Published: August 2022

Background:

The study area is located in the Southern Part (SD) of Iraq, between the Southwestern part of Al-Samawah city and northeastern part of Dhi-Qar Governorate. The lack of surface water for different usages requirements has led to search for new groundwater resources.  The study area is characterized by an arid to semi-arid climate with little rains and increase evaporation.

Materials and Methods:

Gravity methods and using GIS environment were used to delineate the subsurface structural lineaments in Salman Basin (SB) within Al-Muthanna province in Iraqi southern desert (SD). The Centre for Exploration Targeting (CET) was applied to gravity data; we were used CET technique to find any fractures, contact or faults that may occur within the study area. The data processing was carried out by using the OASIS montaj TM. Data is extracted from the Shuttle Radar Topography Mission (SRTM), Digital Elevation Model (DEM) with a spatial resolution of 90 m, and (land-sat 8) Image are used with Arc GIS Environment for delineation of the secondary basins (Abu-Hadeer, Al-kasir, Ashali, Kor al-tair, Shuwija, Abu marys).

Results:

The interpretation of the gravity data shows two prominent sets of lineaments. The first set is taken NW-NE direction perpendicular to the extensional structures, while the second set has NS-EW direction. Areas with high lineament density have the highest permeability, which means they have a higher possibility of gathering groundwater.

Memiliki anak berkebutuhan khusus membawa dampak bagi orang tua. Hal ini disebabkan karena perkembangan anak berkebutuhan khusus tentu berbeda dengan tahap perkembangan di mana anak tersebut memiliki karakteristik dan kebutuhan yang berbeda sehingga memengaruhi praktik parenting atau pola pengasuhan yang dilakukan orangtua. Parenting self-efficacy menjadi pembeda atas keberhasilan orang tua dalam mengasuh anak. Parenting self-efficacy sendiri diterjemahkan sebagai sebuah komponen kognitif dalam kompetensi pengasuhan (parenting) yang menunjukkan persepsi orang tua mengenai kompetensi yang dimilikinya dalam menjalankan perannya sebagai orang tua dan kemampuan untuk mempengaruhi perilaku dan perkembangan anak secara positif. Tujuan diadakannya pengabdian pada masyarakat ini adalah untuk memberikan pemahaman atau psikoedukasi kepada orang tua yang memiliki anak berkebutuhan khusus mengenai pentingnya parenting self efficacy dalam upaya meningkatkan keterlibatan orang tua dan mempebesar kemungkinan keberhasilan treatment yang dijalani oleh anak. Dari psikoedukasi yang telah diberikan, diharapkan orang tua dari anak-anak berkebutuhan khusus dapat mengetahui bagaimana dampak positif parenting self-efficacy orang tua terhadap kemajuan dan keberhasilan treatment anak.
Valuing cultural diversity of cities
Authors: Maré David C , Poot Jacques
Published: August 2022

This paper revisits whether cultural diversity is a source of local production and/or consumption amenities. We adapt the analytical framework of Roback (1982, 1988) and Chen & Rosenthal (2008) to estimate the impact of cultural diversity on city wage and rent premiums from hedonic regressions. We focus on New Zealand which – with high residential mobility and ease of setting up business – is particularly suited to this framework. Additionally, our estimates are based on a very large data set: complete unit record census data on individuals and dwellings in 110 urban areas spanning 32 years. Controlling for observed and unobserved city characteristics, and for the potential endogeneity of diversity, we find that cultural diversity serves as a local positive production amenity and a weakly negative consumption amenity. The results are mostly robust to measuring cultural diversity by birthplace, ethnicity or religion; and to using a range of measures of diversity. We conclude that the presence of people from different cultural backgrounds enhances the profitability of urban firms. In contrast, a city’s population has a weak preference for living near others who are culturally similar to them. The effects are stronger in larger cities.
Housing markets and migration – Evidence from New Zealand
Authors: Hyslop Dean , Le Trinh , Maré David C , Stillman Steven
Published: August 2022

This paper analyses the relationship between local area housing and population size and migrant-status composition, using population data from the 1986–2013 New Zealand Censuses, house sales price data from Quotable Value New Zealand, rent data from the Ministry of Business, Innovation and Employment, and building consents data from Statistics New Zealand. Measured at the Territorial Local Authority and Auckland Ward (TAW) area level, we estimate the elasticity of house prices with respect to population is 0.4-0.65, similar but smaller elasticity of apartment prices, but find no evidence of any local population effects on rents. We also estimate the elasticity of housing quantity with respect to population of about 0.9. Although international migration flows are an important contributor to population fluctuations, we find little evidence of systematic effects of international or domestic migrant composition of the local population on prices or quantity. In particular, despite there being a strong correlation between immigration and house price changes nationally, there is no evidence that local house or apartment prices are positively related to the share of new immigrants in an area. Repeating the analysis for more narrowly defined areas within Auckland, we estimate a smaller house price elasticity with respect to population in the range 0–0.15. Finally, our analysis suggests that longer-term housing supply is relatively elastic, and demand inelastic, with respect to price
Competition and productivity: Do commonly used metrics suggest a relationship?
Authors: Maré David C , Fabling Richard
Published: August 2022

We demonstrate the power of recently redeveloped productivity microdata to produce a range of meaningful competition indicators highlighting different aspects of industry competitiveness. Combining these competition metrics into composite indicators, we summarise the diverse range of competitive environments in New Zealand by clustering industries into four distinct groups. Estimating the relationship between competition and productivity within these groups provides some suggestive results that the tail of unproductive firms may be truncated when competition is greater, in part due to greater selection-to-exit based on productivity. Overall, the limited evidence we find for a direct relationship between competition and productivity does not necessarily imply that the two are unrelated, but more likely reflects that changes in competition in New Zealand over the sample period have not been particularly pronounced, making it difficult to identify a systematic relationship.
