On the Lebesgue nonlinear transformations

In this paper, we introduce a quadratic stochastic operators on the set of all probability measures of a measurable space. We study the dynamics of the Lebesgue quadratic stochastic operator on the set of all Lebesgue measures of the set [0,1]. Namely, we prove the regularity of the Lebesgue quadratic stochastic operatorsComment: 11 page

Which blood group will dominate in Malaysia in the future

A blood group provides an ideal opportunity for the study of human variation without cultural prejudice. It can be easily classified for many different genetically inherited blood typing systems. Also significant is the fact that we rarely take blood types into consideration in selecting mates. A few people know their own type today and no one did prior to 1900. As a result, differences in blood type frequencies around the world are most likely due to other factors than social discrimination. All human populations share the same 29 known blood systems, although they differ in the frequencies of specific types. When we donate blood or have surgery, a small sample is usually taken in advance for at least ABO and Rh systems typing. You inherited your blood types from your parents and the environment in which you live cannot change them. We have learned a good deal about how common each of the ABO blood types is around the world. It is quite clear that the distribution patterns are complex. About 21% of all people in the world share the A allele. The highest frequencies of A are found in small, unrelated populations, especially the Blackfoot Indians of Montana (30-35%), the Australian Aborigines (many groups are 40-53%). Overall in the world, B is the rarest ABO blood allele. Only 16% of humanity have it. Note that it is highest in Central Asia and lowest among the indigenous peoples of the Americas and Australia. The O blood type is very common around the world. About 63% of humans share it. Type O is particularly high in frequency among the indigenous populations of Central and South America, where it approaches 100%. The rest of people in the world are sharing AB blood allele. One of the interesting problems in blood group distributions is that if we know the current blood group distributions of the society then can we predict the blood groups distributions in the future. By concerning this problem, we collected some data from Pahang and Kuala Lumpur states of Malaysia and provided a mathematical model of the human blood group transmission. By means of his model, he tried to predict the future blood group distributions in Malaysia (Pahang and Kuala Lumpur states). In this poster, we are going to present our results

Isoamylase profile of mung bean seedlings treated with high temperature and gibberellic acid

Heat stress is one of the common abiotic stresses and is the most harmful factor affecting the growth and productivity of any crop. Heat stress can reduce number of morphological and physiological properties of any living organism. Gibberellic acid (GA3), a plant growth hormone is also known for resistance of number of abiotic stresses like heat stress. Effect of high temperatures and GA3 were evaluated in terms of amylase isozymes in four mung bean genotypes. Twenty four hours old seedlings of four mung bean genotypes (NM 19-19, NM 20-21, NM 121-123 and NCM 89) were exposed to lethal temperature (50°C), pretreated with 40°C prior to lethal temperature with and without 100 μM GA3. Polyacryamide gel electrophoresis (7.5%) revealed five isoamylases all together in different samples; however, variations were seen among control and treated samples of different genotypes. It was observed that Amy 2 was present in all samples. A very light band of Amy 5 was seen only in treated samples of 0 h of all genotypes, similarly Amy 4 was specific to treated samples at 0 h harvest of NM 20-21 and NCM 89. Application of GA3 during unstressed condition (A1), showed no prominent induction in amylase activity for all genotypes except for NCM 89 at 24 and 72 h. However, the induction in amylase was seen when the pretreatment of 100 μM GA3 was given during mild (B1or B2) or lethal temperature (C) for all genotype at some harvests.Keywords: Gibberellic acid, heat stress, Isoamylase, mung beanAfrican Journal of Biotechnology Vol. 12(13), pp. 1495-149

Effect of heat stress on lipid peroxidation and antioxidant enzymes in mung bean (Vigna radiata L) seedlings

The aim of this research was to estimate the effects of heat stress on lipid peroxidation and antioxidant enzymes in seedlings of four mung bean genotypes (NM 19-19, NM 20-21, NM 121-123 and NCM 89). Sterilized seeds were grown in petri dishes at optimum temperature (30°C) for 24 h, exposed to 50°C for 2 h (lethal temperature) as well as pretreated to 40°C for 1 h prior to 50°C for 2 h. Changes in malondialdehyde (MDA) content which is an indicator of lipid peroxidation and the activity of guaiacol peroxidase (POD), ascorbate peroxidase (APX), superoxide (SOD) and catalase (CAT) were measured. The results showed that the growth in lethal temperature was extremely poor which improved when pretreatment of 40°C was applied before 50°C. The content of MDA in seedlings treated with lethal temperature was highest at any harvest, which reduced when seedlings were pretreated with 40°C prior to lethal stress. Variable response of antioxidant enzymes activity amongst different genotypes was observed. POD and SOD activities increased under stress in all genotypes except in NM 20-21, APX activity also increased under heat stress in all genotypes. However, the activity of CAT showed reduction under stress for NM 19-19 and NM 121-123 but increase in NM 20-21 and NCM 89. Low MDA content and increased antioxidant enzymes under heat stress were observed in NM 19-19, indicating that it was most thermotolerant genotype. However, high MDA content with decreased activity of antioxidant enzymes were detected in NM 20-21 which could be suggested a least thermotolerant genotypeKeywords: Antioxidant enzymes, lethal temperature, mung bean, malandialdehyde, lipid peroxidationAfrican Journal of Biotechnology Vol. 12(21), pp. 3196-320

Multidirectional force and torque sensor for insect flight research

This paper discusses the development of a multidirectional force sensor for the investigation of the flight dynamic of a tethered fly. The proposed sensor combines the well-understood concepts of piezoresistive force sensing with a unique design that allows for the measurement of forces with more than one degree of freedom (DOF). In addition, the system has been fabricated to support the fly inside a virtual reality arena. The sensor is fabricated on a wafer-level using standard MEMS technology, By directly measuring the thrust, lift, yaw and side slip generated by the fly, complex aerodynamics mechanisms due to rapidly rotating and flapping wings can be better understood

Mutation and Chaos in Nonlinear Models of Heredity

In this short communication, we shall explore a nonlinear discrete dynamical system that naturally occurs in population systems to describe a transmission of a trait from parents to their offspring. We consider a Mendelian inheritance for a single gene with three alleles and assume that to form a new generation, each gene has a possibility to mutate, that is, to change into a gene of the other kind. We investigate the derived models. A numerical simulation assists us to get some clear picture about chaotic behaviors of such models.Comment: The paper is 12 page

Fog computing enabled cost-effective distributed summarization of surveillance videos for smart cities

[EN] Fog computing is emerging an attractive paradigm for both academics and industry alike. Fog computing holds potential for new breeds of services and user experience. However, Fog computing is still nascent and requires strong groundwork to adopt as practically feasible, cost-effective, efficient and easily deployable alternate to currently ubiquitous cloud. Fog computing promises to introduce cloud-like services on local network while reducing the cost. In this paper, we present a novel resource efficient framework for distributed video summarization over a multi-region fog computing paradigm. The nodes of the Fog network is based on resource constrained device Raspberry Pi. Surveillance videos are distributed on different nodes and a summary is generated over the Fog network, which is periodically pushed to the cloud to reduce bandwidth consumption. Different realistic workload in the form of a surveillance videos are used to evaluate the proposed system. Experimental results suggest that even by using an extremely limited resource, single board computer, the proposed framework has very little overhead with good scalability over off-the-shelf costly cloud solutions, validating its effectiveness for IoT-assisted smart cities.

IPACK2005-73221 MULTIDIRECTIONAL FORCE AND TORQUE SENSOR FOR INSECT FLIGHT RESEARCH

ABSTRACT This paper focuses on the development of a microsensor system that can simultaneously measure multidirectional forces generated by a tethered fly. The proposed sensor combines the well-understood concepts of piezoresistive force sensing with a very unique design that not only allows the measurement forces with more than one degree of freedom (DOF) but will simultaneously support the fly inside a virtual reality arena. The sensor is fabricated on a wafer-level using standard MicroElectro-Mechanical System or MEMS technology. By a directly measuring the thrust, lift, yaw and side slip generated by the fly, complex aerodynamics mechanisms due to rapidly rotating and flapping wings can be better understood
