Completely Positive Map from M4(C) to M5(C) on Positive Semidefinite Matrices

Abstract/Overview Positive Maps Are Essential In the Description of Quantum Systems. However, Characterization Of The Structure Of The Set Of All Positive Maps Is A Challenge In Mathematics And Mathematical Physics. We Construct A Linear Positive Map From M4 To M5 And State The Conditions Under Which They Are Positive And Completely Positive (Copositivity Of Positive).

Jump Diffusion Logistic Brownian Motion with Dividend Yielding Asset

Abstract/Overview Jump diffusion processes have been used in modern finance to capture discontinuous behavior in asset pricing. Logistic Brownian motion for asset security prices shows that naturally asset security prices would not usually shoot indefinitely due to the regulating factor that may limit the asset prices. Geometric Brownian motion cannot accurately reflect all behaviors of stock quotation therefore, Merton who was involved in the process of developing the Black-Scholes model...

Nutritional Composition and Sensory Properties of Wheat Muffins Enriched with Gonimbrasia Zambesina, Walker Caterpillar Four

Abstract/Overview Sub-Saharan Africa still bears the greatest forms of malnutrition. Attention is shifting to the use of edible insects in forms which are acceptable to people irrespective of their social status and level of civilization in efforts to alleviate protein malnutrition. Gonimbrasia zambesina (Lepidoptera: Saturniidae) caterpillars emerge seasonally in the coastal part of Kenya and despite their rich nutritional profile, their consumption is low. This study was thus undertaken...

Effect of Nitrogen Nutrition on the Intensity of Cercospora Leaf Spot of Mulberry

Abstract/Overview Leaf spot (Cercospora moricola, Cooke) is a disease that negatively influences the yield of mulberry (Morus alba L.) plants. To determine the effect of nitrogen levels on the incidence and severity of leaf spot an experiment was carried out on mulberry plants. The nitrogen levels included 0, 100, 200 and 300 kg ha-1 ,which were applied in two splits coinciding with the two rainy seasons. The study design was randomized complete block design (RCBD) with three replications...

Physicochemical and Functional Properties of Edible Dung Beetle Larvae (Scarabaeus satyrus) Flours and Oils and their Significance in Human Nutrition

Abstract/Overview The potential of edible insects in alleviating the nutritional challenges facing humans has led to an increased interest in their utilization. Edible insects contain substantial amounts of protein and fats, which are very important macronutrients that confer useful functional and physicochemical properties to foods. However, the functional properties of these nutrients have not been given sufficient attention, limiting their use as ingredients in diets and food products....

Growth and Economic Performance of African Catfish (Clarias gariepinus Burchell,1822) Fed Diets Containing Black Soldier Fly Larvae Hermetia illucens Linnaeus, 1758)

Abstract/Overview Insect meals have been proposed as a potential alternative protein source for replacing fishmeal (FM), the key ingredient in aquaculture diets, yet is the most scarce and expensive. However, not much work has been done on the effects of replacing FM with black soldier fly (Hermetia illucens ) larvae meal (BSFLM) on the growth and economic performance of African catfish (Clarias gariepinus) fingerlings. This study investigated the effect of replacing FM with BSFLM on the ...

Effects of Drying on the Nutritional, Sensory and Microbiological Quality of Edible Stinkbug (encosternum delgorguei)

Abstract/Overview Entomophagy has recently gained attention as a potential solution to the problems of food and nutritional security. One example is the consumption of edible stinkbug. Different drying techniques may affect the nutritional, microbiological and sensory properties of the edible stinkbugs. Thus, the study assessed the effects of toasting, microwave, oven and sun drying on the nutritional composition, microbiological quality and sensory attributes of processed edible stinkbug...

Topological Data Analysis of COVID-19 Using Artificial Intelligence and Machine Learning Techniques in Big Datasets of Hausdorff Spaces

Abstract/Overview In this paper, we carry out an in-depth topological data analysis of COVID-19 pandemic using artificial intelligence and machine learning techniques. We show the distribution patterns of the pandemic all over the world, when it was at its peak, with respect to big datasets in Hausdorff spaces. The results show that the world areas, which experience a lot of cold seasons, were affected most.

Use of Information Communication Technologies by Cricket Farmers

Abstract/Overview Cricket farming is an upcoming enterprise to Most households in rural communities. Apparently, there is no documented evidence on how farmers access agricultural information on cricket value chain. This study was carried out to assess the use of information communication technologies (ICTs) by farmers to access value chain information. ICTs application in cricket farming means ease to access cricket value chain information and improved interaction between cricket farmers...

Variability in Nutrient Composition of the Edible Long- Hornedgrasshopper (Ruspolia Differens) in Uganda and its Potential in Alleviating Food Insecurity

Abstract/Overview Ruspolia differens Serville (Orthoptera: Tettigonidae) is a highly nutritious and luxurious insect delicacy that is consumed as a food source in many African countries. However, the nutrient profile of R. differens in different geographical regions have received limited research interest. Here, we provide comprehensive evidence of geographical impact on the nutrient profile of R. differens and its potential to meet the recommended dietary intake of the population. Our re...

Computation of the Fault-Tolerant Metric Dimension of Certain Networks

Abstract *e notion of metric dimension originated in the twentieth century by the work done by Slater [1, 2] and latter independently by Harary and Melter [2]. *e initial concept was introduced to locate the intruder in any network but the development and impact of the notion was far reaching in coming years. Several applications of metric related network parameters can be seen in social networking, navigation, communications, and engineering, pharmaceutical chemistry. *e fault tolerance of ...

Classification of Ideals in Banach Spaces

Abstract Let an operator T belong to an operator ideal J, then for any operators A and B which can be composed with T as BTA then BTA J. Indeed, J contains the class of finite rank Banach Space operators. Now given L(X, Y ). Then J(X, Y ) L(X, Y ) such that J(X Y ) = {T : X Y : T }. Thus an operator ideal is a subclass J of L containing every identity operator acting on a one-dimensional Banach space such that: S + T J(X, Y ) where S, T J(X, Y ). If W,Z,X, Y ,A L(W,X),B L(Y,Z) then BTA J(W,Z...

Mathematical Modelling and Simulation of Competition for Students’ Population Via Influence And Economic Factors With Holling Type Ii Response

Abstract The increase in Kenyan population attracted the establishment of more schools, both public schools and private schools. This was due to the need to cater for the increasing number of students being enrolled in schools. Moreover, the dynamics of students’ population both in public schools and private schools have created the changes in the schools’ population. This occurs through transfer from one category of school to the other, through completion of the learning period and thro...

On Certain Spaces of Ideal Operators

Abstract We determine some important spaces of ideal operators and ideal characteristics. Special consideration is given to Frechet spaces, Spaces of finite rank operators and spaces of Hahn-Banach extension operators. The characteristics of ideals and related properties in these spaces as well as in some of their dual spaces are obtained.

Matrices of the Zero Divisor Graphs of Classes of 3-Radical Zero Completely Primary Finite Rings

Abstract The study of finite completely primary rings through the zero divisor graphs, the unit groups and their associated matrices, and the automorphism groups have attracted much attention in the recent past. For the Galois ring R′ and the 2-radical zero finite rings, the mentioned algebraic structures are well understood. Studies on the 3-radical zero finite rings have also been done for the unit groups and the zero divisor graphs Γ(R). However, the characterization of the matrices as...
