Design and Implementation of Autopilot System for Quadcopter Firas

In this paper, a full approach of modeling and control of a four rotor unmanned air vehicle (UAV) known as quadcopter aircraft is presented. The main features of the quadcopter’s structure are across-shaped aerial vehicle, cross intersection columns leading to composition of two diagonals of a square. Four motors have been attached to the end of the cross intersection. The body angular rate ( ) of all motors is the key to the control of the quadcopter. The dynamics system modeling is examined to understand the force growth in play. The control algorithm is represented by the smart Fuzzy controller address the stability and robustness. The genetic algorithm (GA) is involved in constructing the flight controller due to its effectiveness and efficiency in optimization of the control systems. The control strategies represented by the smart Fuzzy controller was linked with the GA to obtain further improvements in the system response in both the transient and steady states. The GA is used as an optimization technique because it is becoming a very common tool for resolving optimization problems and it is employed to effectively secure optimal solutions. The Matlab Simulink is a great tool which was used to test the efficiency and the accuracy of the developed system.
Analysis of Herpes Simplex 1 and 2 IgG and IgM Antibodies in Pregnant Women and their Neonates

Objectives: (1) Assessment of prevalence of herpes simplex virus 1 (HSV-1) and herpes simplex virus 2 (HSV-2) antibodies in pregnant mothers visiting the antenatal clinic and delivery room in King Fahd Hospital of the University (KFHU) in Al-Khobar, Saudi Arabia and (2) assessment of prevalence of HSV-1 and HSV-2 antibodies in cord blood in the delivery room in KFHU. Material and methods: Laboratory methods used included the type-specific enzyme linked immunosorbent assay to assess HSV-1 and HSV-2 IgM and IgG antibodies in the sera. Results: generated from the samples of pregnant mothers (N=459) showed that 90.5% have detectable levels of HSV-1 IgG antibodies, 6.5% have detectable level of HSV-2 IgG antibodies, 4.3% have detectable levels of HSV-1 IgM antibodies and 0.5% have detectable level of HSV-2 IgM antibodies. As for the cord blood samples (N=459), the IgG antibody reactivity was exactly the same as the corresponding mothers for both HSV-1 and HSV-2. However, only three cord blood samples have detectable levels of HSV-1 IgM antibodies, and none have detectable antibodies for HSV-2 IgM antibodies. Conclusions: Because both HSV-1 and HSV-2 can infect pregnant women and their neonates, assessment of HSV infection in pregnant women and neonates will help in proper management of HSV infection and will also be useful for epidemiological purposes.
Assessment of 3-D Printing Technologies for Millimeter-Wave Reflectors

Three different 3-D printing technologies—stereolithography, fused deposition modeling, and HP Multi Jet Fusion technology—are compared to build a parabolic reflector operating at 100 GHz. Fabrication tolerance and surface roughness before and after metallization are accurately measured. The performance of the reflectors is measured in the near field, and it is compared against an optical grade reflector. In this way, the performance of the final product is thoroughly assessed.
Effects of episodic flooding on the net ecosystem CO2 exchange of a supratidal wetland in the Yellow River Delta

Episodic flooding due to intense rainfall events is characteristic in many wetlands, which may modify wetland‐atmosphere exchange of CO2. However, the degree to which episodic flooding affects net ecosystem CO2 exchange (NEE) is poorly documented in supratidal wetlands of coastal zone, where rainfall‐driven episodic flooding often occurs. To address this issue, the ecosystem CO2 fluxes were continuously measured using the eddy covariance technique for 4 years (2010–2013) in a supratidal wetland in the Yellow River Delta. Our results showed that over the growing season, the daily average uptake in the supratidal wetland was −1.4, −1.3, −1.0, and −1.3 g C m−2 d−1 for 2010, 2011, 2012, and 2013, respectively. On the annual scale, the supratidal wetland functioned as a strong sink for atmospheric CO2, with the annual NEE of −223, −164, and −247 g C m−2 yr−1 for 2011, 2012, and 2013, respectively. The mean diurnal pattern of NEE exhibited a smaller range of variation before episodic flooding than after it. Episodic flooding reduced the average daytime net CO2 uptake and the maximum rates of photosynthesis. In addition, flooding clearly suppressed the nighttime CO2 release from the wetland but increased its temperature sensitivity. Therefore, effects of episodic flooding on the direction and magnitude of NEE should be considered when predicting the ecosystem responses to future climate change in supratidal wetlands.
Clinical, Hematological, and Biochemical Alterations in Olive Flounder Paralichthys olivaceus Following Experimental Infection by Vibrio scophthalmi

Hematological analysis can provide crucial information for monitoring the health of fish. However, there is no current information available regarding hematological changes in olive flounder following infection by Vibrio scophthalmi. In this study, hematological and biochemical alterations were determined in olive flounder infected by the high virulence strain (HVS) and low virulence strain (LVS) of V. scophthalmi. Survival in serum, skin mucus, and macrophages of olive flounder was also compared between the HVS and LVS. The results demonstrated that the hematocrit value in infected fish declined from 23.4% at 0 h to 18.0% at 168 h post infection. The total protein concentration in fish infected with the HVS was significantly higher than in fish infected with the LVS and a non-infected control. Lysozyme activity was significantly different between infected and control fish. The HVS survived in serum and cell numbers increased substantially, while cell numbers of the LVS in serum decreased. These changes in hematological characteristics in fish infected by V. scophthalmi can be used as an effective and sensitive index to monitor the physiological and pathological conditions of fish. The survival and reproduction of V. scophthalmi in host serum, skin mucus, and macrophages play a major role in systemic infection and can serve as a virulence indicator for different strains.
How Quantum is a "Quantum Walk"?

We consider the question of characterizing quantumness of so-called quantum random walks. Our measure is based on comparing a quantum walk with its associated nearest classical random walk, and transcends the existing measures in finding quantum properties. We also introduce a technique to attribute a classical random walk to a quantum walk by a contraction noise channel. We then define total quantumness for a walk as the minimum quantum relative entropy of a walker with respect to its genuinely classical cousin. This stronger nonclassicality measure is shown to include quantum coherence as well, and thus can have numerous applications. We discuss several examples to represent how this measure behaves under various quantum or classical noise scenarios. In particular, we employ our quantumness measures to investigate energy transfer or quantum transport on graphs, which has recently gained much attention and applications, e.g., in photosynthesis. We show that a nonvanishing quantumness measure unambiguously implies that a quantum-walk-based process can reach a higher energy/transport efficiency compared to its classical counterparts, and that decay noises do not necessarily kill all quantum effects in such processes---whence providing a partial explanation for why such processes may outperform relevant classical effects.
Title The effects of cardioactive drugs on cardiomyocytes derived from human induced pluripotent stem cells

Developing effective drug therapies for arrhythmic diseases is hampered by the fact that the same drug can work well in some individuals but not in others. Human induced pluripotent stem (iPS) cells have been vetted as useful tools for drug screening. However, cardioactive drugs have not been shown to have the same effects on iPS cell-derived human cardiomyocytes as on embryonic stem (ES) cell-derived cardiomyocytes or human cardiomyocytes in a clinical setting. Here we show that current cardioactive drugs affect the beating frequency and contractility of iPS cell-derived cardiomyocytes in much the same way as they do ES cell-derived cardiomyocytes, and the results were compatible with empirical results in the clinic. Thus, human iPS cells could become an attractive tool to investigate the effects of cardioactive drugs at the individual level and to screen for individually tailored drugs against cardiac arrhythmic diseases.
University's Entrepreneurship Education: Creating Meaningful Impression for New Generation

Entrepreneurship has a tremendous impact on the economic development of a country. As can be expected, many public policies foster the development of self- entrepreneurship in times of unemployment, praise the creation of firms and con- sider the willingness to start new ventures as a sign of good fortune. Are those behaviours inherent to a human being, to his genetic code, his psychology or can students, younger children or even adults be taught to become entrepreneurs? What should be the position of universities, of policy makers and how much does it matter for a country? This book presents several articles, following different research approaches to answer those difficult questions. The researchers explore in particular the psychology of entrepreneurship, the role of academia and the macroeconomic impact of entrepreneurship.
On the Usability of Parallel Coordinates Plots for Representing Behavioral Attributes in LMS Platforms

This paper investigates the suitability of using Data Visualization, specifically Parallel Coordinates Plots (PCP), as an instrument for helping distance learning instructors identify students with poor performance. To answer this question, we developed a web application that lets users generate and interact with PCPs and evaluated it with usability tests inspired by the NOVIS framework — a usability framework specifically designed for evaluating data visualizations. The results show that PCPs and Data Visualization are perceived, by distance learning instructors, as an invaluable tool for following student progress on Virtual Learning Environments.
The potential of unmanned aerial systems for sea turtle research and conservation: A review and future directions

The use of satellite systems and manned aircraft surveys for remote data collection has been shown to be transformative for sea turtle conservation and research by enabling the collection of data on turtles and their habitats over larger areas than can be achieved by surveys on foot or by boat. Unmanned aerial vehicles (UAVs) or drones are increasingly being adopted to gather data, at previously unprecedented spatial and temporal resolutions in diverse geographic locations. This easily accessible, low-cost tool is improving existing research methods and enabling novel approaches in marine turtle ecology and conservation. Here we review the diverse ways in which incorporating inexpensive UAVs may reduce costs and field time while improving safety and data quality and quantity over existing methods for studies on turtle nesting, at-sea distribution and behaviour surveys, as well as expanding into new avenues such as surveillance against illegal take. Furthermore, we highlight the impact that high-quality aerial imagery captured by UAVs can have for public outreach and engagement. This technology does not come without challenges. We discuss the potential constraints of these systems within the ethical and legal frameworks which researchers must operate and the difficulties that can result with regard to storage and analysis of large amounts of imagery. We then suggest areas where technological development could further expand the utility of UAVs as data-gathering tools; for example, functioning as downloading nodes for data collected by sensors placed on turtles. Development of methods for the use of UAVs in sea turtle research will serve as case studies for use with other marine and terrestrial taxa.
Evaluation of pre/post-fire differenced spectral indices for assessing burn severity in a Mediterranean environment with Landsat Thematic Mapper

In this study several pre/post-fire differenced spectral indices for assessing burn severity in a Mediterranean environment are evaluated. GeoCBI (Geo Composite Burn Index) field data of burn severity were correlated with remotely sensed measures, based on the NBR (Normalized Burn Ratio), the NDMI (Normalized Difference Moisture Index) and the NDVI (Normalized Difference Vegetation Index). In addition, the strength of the correlation was evaluated for specific fuel types and the influence of the regression model type is pointed out. The NBR was the best remotely sensed index for assessing burn severity, followed by the NDMI and the NDVI. For this case study of the 2007 Peloponnese fires, results show that the GeoCBI–dNBR (differenced NBR) approach yields a moderate–high R 2 = 0.65. Absolute indices outperformed their relative equivalents, which accounted for pre-fire vegetation state. The GeoCBI–dNBR relationship was stronger for forested ecotypes than for shrub lands. The relationship between the field data and the dNBR and dNDMI (differenced NDMI) was nonlinear, while the GeoCBI–dNDVI (differenced NDVI) relationship appeared linear.
OXYGEN UPTAKE AND TRANSPORT DURING HYPOXIC EXPOSURE IN THE STURGEON

Gill ventilation, stroke volume and frequency, ! ~,, 02 utilization and oxygen uptake, and dorsal aortic blood oxygen tension, content, pH and oxygen affinity have been determined during normoxia and during a range of hypoxic exposures in the sturgeon, Acipenser transmontanus. In air-equilibrated water gill ventilation was 350 ml/kg/min, ! o utilization was 35 40! 'i, and oxygen uptake at 15 C was 55 60 ml O2/kg/h. Dorsal aortic blood Po~ was 90 m m Hg and blood 02 content at a normal pHa of 7.84 was 7.0 voI ";,. Vg fell considerably through a reduction in branchial stroke volume when Pxo: was reduced from 150 to 100 mm Hg. Al though ,;, utilization remained unchanged, Vo2 was halved, clearly identifying Acipenser as an 02 conformer with a critical 02 tension just below air saturation. At a PIo_~ of 60 mm Hg ~/o2 was only 15'),o of that at normoxic levels falling to only 5')o at a Plo~ of 30 mm Hg. There was no hypoxic bradycardia. There was no repayment of an oxygen debt even after severe hypoxic exposure in Acipenser, and pHa remained unchanged under all experimental conditions, a response incompatible with lactate or succinate production. It is concluded that the sturgeon reduces total energy expenditure during hypoxic exposure, rather than switching from aerobic to anaerobic metabolism.

RAF Kinases: Pathway, Modulation and Modeling

The Ras/RAF/MEK/ERK cascade is a central cellular signal transduction pathway involved in cell proliferation, differentiation, and survival where RAF kinases are pivotal kinases implicated in cancer. The development of specific irreversible kinase inhibitors is a rewarding but difficult aim. A novel synthetic approach including a lyophilization step allowed us the synthesis of a diphenyl urea compound with an epoxide moiety (compound 1). Compound 1 possessed inhibitory activity in vitro. In cell culture experiments, a strong activation of the RAF signaling pathway was observed, an effect which is known from several other RAF kinase inhibitors and is here reported for the first time for a diphenyl urea compound. Furthermore, we developed a mathematical model of the Ras/RAF/MEK/ERK cascade demonstrating how stimuli induce different signal patterns and thereby different cellular responses, depending on the ratio between B-RAF and C-RAF. Additionally the effect of the tumor suppressor DiRas3 (also known as Noey2 or ARHI) on RAF signaling was studied. I could show that DiRas3 down-regulates the mitogenic pathway by inhibition of MEK.
The autodependogram: a graphical device to investigate serial dependences

In this article the serial dependences between the observed time series and the lagged series, taken into account one‐by‐one, are graphically analysed by what we have chosen to call the ‘autodependogram’. This tool is a sort of natural nonlinear counterpart of the well‐known autocorrelogram used in the linear context. The autodependogram is based on the simple idea of using, instead of autocorrelations at varying time lags, the χ2‐test statistics applied to convenient contingency tables. The efficacy of this graphical device is confirmed by real and artificial time series and by simulations from certain classes of well‐known models, characterized by randomness and by different kinds of linear and nonlinear dependences.
MEMORY : SYSTEMS , ABILITIES , DEFICITS , DISORDERS

Memory function is critical to daily life, and includes a variety of specific abilities that, at their core, enable information to be stored (at least briefly) for future use. Most memory abilities are evolutionarily primitive but have been elaborated at least to some degree in humans, although episodic memory is thought to be evolutionarily recent and its existence in many animal species is debated. Four major forms of memory are episodic, semantic, working, and procedural memory (Budson and Price, 2005, 2007). The focus of this discussion is on episodic memory, but the other forms of memory will be briefly reviewed since the clinical evaluation (and experimental probing) of a specific memory ability usually requires the interpretation of function in these other domains.
Linux Memory Forensics: Expanding Rekall for Userland Investigation

The field of memory forensics is getting more important in forensic investigations for obtaining valuable data of a running system. Besides kernel artifacts, there might be also plenty of interesting data in the heap of a user space process, but unfortunately, that area has not yet received the attention it deserves in the forensic field. This paper shows that the heap of user applications may also be a rich source of information including data like credentials that can be helpful in a forensic investigation. With the help of the HeapAnalysis plugins, previously published by Block, we examined the heap of selected Linux userland software and managed to identify data of interest and also certain application-internal structures, which link those data snippets together. The result of our analysis is a set of plugins for the Rekall framework, enabling an investigator to automatically extract process-related information such as login credentials, command history and file information for those applications.
On the Need of Class Ratio Insensitive Drift Tests for Data Streams

Early approaches to detect concept drifts in data streams without actual class labels aim at minimizing external labeling costs. However, their functionality is dubious when presented with changes in the proportion of the classes over time, as such methods keep reporting concept drifts that would not damage the performance of the current classification model. In this paper, we present an approach that can detect changes in the distribution of the features that is insensitive to changes in the distribution of the classes. The method also provides an estimate of the current class ratio and use it to adapt the threshold of a classification model trained with a balanced data. We show that the classification performance achieved by such a modified classifier is greater than that of a classifier trained with the same class distribution as the current imbalanced data.
Expression of p 16 predicts poor outcome for patients with gastrointestinal stromal tumors

Gastrointestinal stromal tumors are the most common mesenchymal tumors found in the gastrointestinal tract. Their biological behavior is still predicted by a consensus scheme proposed by the U.S. National Institutes of Health. In this study, we investigated the prognostic significance of p16 protein expression in gastrointestinal stromal tumors. Expression of p16 protein was observed in 42.4% (92/217) of tumors and was significantly associated with a high mitotic count, tumor necrosis, recurrence or metastasis, and a higher-risk group. Patients with p16expressing gastrointestinal stromal tumors showed a shorter overall survival and disease-free survival than those without p16 expression; however, p16 expression was not an independent prognostic factor. The risk of malignant behavior and the presence of recurrence or metastasis were independent prognostic factors. Expression of p16 protein predicts poor outcome and can be a useful marker to predict relapse or metastasis and aggressive behavior in gastrointestinal stromal tumors.
A New [Combinatorial] Proof of the Commutativity of Matching Polynomials for Cycles

We prove some functional equations involving the (classical) matching polynomials of path and cycle graphs and the $d$-matching polynomial of a cycle graph. A matching in a (finite) graph $G$ is a subset of edges no two of which share a vertex, and the matching polynomial of $G$ is a generating function encoding the numbers of matchings in $G$ of each size. The $d$-matching polynomial is a weighted average of matching polynomials of degree-$d$ covers, and was introduced in a paper of Hall, Puder, and Sawin. Let $\mathcal{C}_n$ and $\mathcal{P}_n$ denote the respective matching polynomials of the cycle and path graphs on $n$ vertices, and let $\mathcal{C}_{n,d}$ denote the $d$-matching polynomial of the cycle $C_n$. We give a purely combinatorial proof that $\mathcal{C}_k (\mathcal{C}_n (x)) = \mathcal{C}_{kn} (x)$ en route to proving a conjecture made by Hall: that $\mathcal{C}_{n,d} (x) = \mathcal{P}_d (\mathcal{C}_n (x))$.
A spread-spectrum clock generator with triangular modulation

In this paper, a spread-spectrum clock generator (SSCG) with triangular modulation is presented. Only a divider and a programmable charge pump are added into a conventional clock generator to accomplish the spread-spectrum function. The proposed circuit has been fabricated in a 0.35-/spl mu/m CMOS single-poly quadruple-metal process. The proposed SSCG can generate clocks of 66, 133, and 266 MHz with center spread ratios of 0.5%, 1%, 1.5%, 2%, and 2.5%. Experimental results confirm the theoretical analyses.
Migrants' New Transnational Habitus: Rethinking Migration Through a Cosmopolitan Lens in the Digital Age

This article puts forward a cosmopolitan reading of international migration, focusing on the role played by ICTs in generating new ways of living together and acting transnationally in the digital era. After underlining some of the complex dimensions of the transnational debate and the limits of methodological nationalism, I will argue that revisiting the national–transnational nexus by adopting an ‘inclusive cosmopolitan’ stance would lead to a better understanding of the dialogically ubiquitous condition of the modern migrant. An analysis of Internet use by Romanian professionals in Toronto and their transnational families will shed light on the mechanisms through which ICTs produce connected lifestyles, enhance the capacity to harness otherness, and facilitate socialisation beyond borders, thus generating new transnational habitus.
