Household Predictors of Incidence of Malaria in Northern Uganda: Its Implication for Future Malaria Control

Background: Use of indoor residual spraying (IRS), long-lasting insecticidal nets (LLINS) and treatment with artemisinin-based combination therapy (ACT) have been greatly promoted in northern Uganda but the region still records highest number of malaria cases with prevalence up to 63%. This study assesses household predicators of malaria in the region and its impact on incidence of malaria at household levels.Methods: A cross-sectional study was conducted in four districts of Gulu, Oyam, Kitgum and Agago covering sixteen known hyper-endemics villages with high malaria burden in northern Uganda. In total, 193 households were surveyed. Data was collected through pre-tested structured questionnaires and systematically coded and analyzed using R software.Results:Women headed 58% of the 193 households surveyed. Six hundred and five (605) individuals were declared to have spent a night in the 193 households surveyed. Nighttime is when mosquitoes mostly gain access to victims in the study area. On average, there were two bed nets per household and out of the 605 individuals declared, 502 502 (86%) spent the night prior to interview under a bed net. Despite this effort, these households still reported malaria incidences in the last three months. Overall, children were prone to malaria more than adults by a ratio of 3:2, and in general, malaria incidences were strongly related to lack of bed nets or use thereof, and also linked directly to the number of individuals in a house. Households without bed nets controlled malaria by means of IRS in combination with closing doors (with the hope of keeping mosquitos at bay), draining stagnant water pool where mosquitos lay their eggs, trimming mosquito covers (grass) around homestead and/or receiving treatment after malaria incidences. When given a choice between insecticides (IRS) and treated bed nets, 1 in 3 households preferred treated bed nets. At the same time, bed nets were perceived unnecessary once IRS was applied. If true, the driving force to spraying insecticides indoor then becomes lack of a bed net. Conclusions:Household predicators of incidence of malaria in northern Uganda includes bed nets, use of treated bed nets, and indoor residual spraying with households not practicing any of these bearing the heaviest burden of malaria. Hierarchical clustering on principal components (HCPC) clusters households into four types in northern Uganda, 1) household that use bed nets and sleep in houses sprayed with insecticides; 2) households that use bed nets but no indoor residual spraying with insecticides; 3) households that have no bed nets and no indoor residual spraying; and 4) test bed nets before use. An opportunity therefore arises for tailoring malaria messages to fit each cluster of households given that clustering here appears not to be random. Malaria incidence was higher in children as compared to the adults that necessities having guidelines for management of interventions in local community setting.
Passive Synthetic Aperture Radar Imaging Using Commercial OFDM Communication Networks

Abstract : Modern communication systems provide myriad opportunities for passive radar applications. OFDM is a popular waveform used widely in wireless communication networks today. Understanding the structure of these networks becomes critical in future passive radar systems design and concept development. This research develops collection and signal processing models to produce passive SAR ground images using OFDM communication networks. The OFDM-based WiMAX network is selected as a relevant example and is evaluated as a viable source for radar ground imaging. The monostatic and bistatic phase history models for OFDM are derived and validated with experimental single dimensional data. An airborne passive collection model is defined and signal processing approaches are proposed providing practical solutions to passive SAR imaging scenarios. Finally, experimental SAR images using general OFDM and WiMAX waveforms are shown to validate the overarching signal processing concept.

Accountable

This chapter explores attempts to hold sovereign actors accountable in the legal sense. At the same time, the chapter shows that legal accountability is precisely what the classic theory of sovereignty rules out—and precisely what people have struggled for, in episode after episode. It also explores startling cases where mere criticism is reviled as an outrageous affront to sovereignty. These two matters are tied: legal accountability turns out to be another kind of affront. The chapter also addresses accountability in terms of international law and politics. It considers the actions of diplomats in the face of sovereign authority, and also discusses the United Nations under this context.
An Evaluation of the Architecture Analysis and Design Language for Automobile Applications : Technical Report: C4-01 TR M52

Due to the growing complexity of software systems in modern automo- biles, the software architecture design phase becomes more and more important. Useful tools and languages are speci¯cally needed to man- age this complexity. Recently, the Architecture Analysis and Design Language (AADL) has been proposed as a modeling language for crit- ical systems and this language is becoming increasingly popular in the automobile industry. In order to test whether AADL is suitable for modeling software in automobile systems, we provide in this technical report a critical evaluation of the capabilities and features of this new language. Speci¯cally, we evaluate AADL against a set of requirements that have been identi¯ed based on an exhaustive literature review and experiences gained from modeling an Adaptive Cruise Control (ACC) in AADL. The objective of this paper is to evaluate the suitability of AADL and identify gaps that would require future research and devel- opment.
Projection-type methods with alternating inertial steps for solving multivalued variational inequalities beyond monotonicity

In solving variational inequalities, the inertial extrapolation step is a highly powerful tool in algorithmic designs and analyses mainly due to the improved convergence speed that it contributes to the algorithms. However, it has been discovered that the presence of the inertial extrapolation steps in these methods for solving variational inequalities makes them lose some of their attractive properties, for example, the Fejér monotonicity (with respect to the solution set) of the sequence generated by projection-type methods for solving variational inequalities is lost when the iterative steps involve an inertial term, which makes these methods sometimes not converge faster than the corresponding algorithms without an inertial term. To avoid such a situation, we present two new projection-type methods with alternated inertial extrapolation steps for solving multivalued variational inequality problems, which inherit the Fejér monotonicity property of the projection-type method to some extent. Furthermore, we prove the convergence of the sequence generated by our methods under much relaxed assumptions on the inertial extrapolation factor and the multivalued mapping associated with the problem. Moreover, we establish the convergence rate of our methods and provide several numerical experiments of the new methods in comparison with other related methods in the literature.
Measuring the Average Thickness of a Plate Using a Bayesian Method and Free Vibration Data

Abstract : In this paper a model-based approach is taken to identify certain geometric and/or material parameters for a structure. Specifically, the focus is on determining the average thickness of a thin, fully-clamped plate undergoing free vibration. The methodology is described and then implemented in an experimental setting using the measured free response of a plate. The practical SHM scenario driving this investigation is corrosion, since the extent of corrosion damage is often described in terms of the effective thickness of the plate, i.e. how much of the plate s thickness is still structurally intact. Data are gathered from three resistive strain gages, placed at arbitrary locations and orientations. Using the experimental response and a finite element model, a Bayesian approach is taken to estimate the plate thickness, h. This thickness could then be used to infer the extent of the damage, had corrosion been present. The results show that even with limited, noisy vibration data valuable information regarding the geometry and material characteristics of a plate can be successfully estimated.
Institutional Arrangement, Technological Innovation and Application Evolution: The Rise of China’S Emerging Computing Infrastructure

This paper tries to explore the interaction of institutional arrangement, technological innovation and application evolution underlying the impressive growth of China’s computing infrastructure. Drawing upon the actor-network theory, we construct a framework to explain how the elements identified forge the evolution of the sector. Our study hopes to provide the analytical lens and explanatory power to probe this growth process under the emerging contexts. We conduct an in-depth case study on the growth of China’s emerging computing infrastructure to justify the framework. Chinese government has been deeply involved in the development of the computing infrastructures including the systems of supercomputing and cloud computing to build a nationwide computing backbone network. In the resent emerging of cloud computing, the networks which involved in much more diversified actors with heterogeneous interests are shaping under a more open setting. However, the facility-oriented strategies by the dominant state-owned players still exert great challenge to the cloud computing development which needs sustainable benefits generated from the infrastructure. Our paper tries to provide a systematic understanding on the growth of China’s emerging computing infrastructure and offer some important insights to the emerging industries in other large emerging countries.
Biomimetic Micro Air Vehicle Testing Development and Small Scale Flapping-Wing Analysis

Abstract : The purpose of this research was to develop testing methods capable of analyzing the performance of a miniature flapping-wing mechanism that can later be adapted for the development a biomimetic flapping-wing micro air vehicle (MAV). Three small scale flapping mechanisms capable of single plane flapping, flapping with active pitch control, and flapping/pitch with out-of-plane movement were designed using SolidWorks. The flapping-only model was fabricated on an Objet 3-dimensional printer and miscellaneous parts. The flapping mechanism was mounted on a supported by air bearings, and thrust was measured for a variety of conditions. The testing was conducted using wings composed of carbon fiber and Mylar in four different size configurations, with flapping speeds ranging from 3.5 - 15 Hertz. The thrust was measured using an axially mounted 50 gram load cell which resulted in an accuracy of +/- 0.1 gram. The flapping mechanism was then mounted on a 6-component force balance to measure dynamic loading, which demonstrated the ability to gather time-accurate data within a single flapping stroke at speeds as high as 15 Hz. High speed cameras were also used for capturing images of how the structure of the wing changed at various testing conditions. Overall this research successfully demonstrated testing procedures that can be utilized in developing small scale flapping-wing micro air vehicles.
ER documents categorization and explanation

Background Emergency room reports are a specific kind of text, posing specific challenges to natural language processing techniques. In this setting, violence episodes on women, elderly and children are often under-reported. Categorizing textual descriptions as containing violence-related injuries vs. non-violence-related injuries, is thus a relevant task, to the ends of devising alerting mechanisms to track violence episodes. Methods We present a system to detect episodes of violence from the textual descriptions contained in emergency room reports. It employs a deep neural network for categorizing textual ER reports data. Additionally, the system complements such output by making explicit which elements corroborate the interpretation of the record as reporting about violence-related injuries. To these ends we designed a novel hybrid technique for filling semantic frames that employs distributed representations of the terms herein, along with syntactic and semantic information. Results We tested our system on a set of real data of emergency room reports, coming from an Italian branch of the EU-Injury Database (EU-IDB) project, annotated by hospital staff. Our experimentation shows that the system produces accurate categorization (of violent vs. non violent records), paired with interesting results on the explanation of such output. At times, it also allowed unveiling annotation errors committed by hospital staff. Conclusions In the last few years deep architectures and word embeddings have been compared to a tsunami hitting AI and the area concerned with natural language processing. Only at a later time we have been realizing that the stunning output of deep networks needed to be explained: our proposal, combining distributed and symbolic (frame-like) representations are a possible answer to this pressing request for interpretability. Although the present application is focused on the medical domain, the proposed methodology is general and, in principle, it can be extended to further application areas and categorization tasks.
Perspectives of chitosan nanofiber/film scaffolds with bone marrow stromal cells in tissue engineering and wound dressing

Objective (s): Several methods have been proposed for repairing defects and damages, one of which is cell therapy. Bone marrow stromal cells seem to be suitable for this purpose. On the other hand, many biometric materials are used to improve and correct the defects in the body. Nanofibers are widely used in the medical industry, especially in tissue engineering, as scaffolds in wound healing and wound dressing. Chitosan/polyethylene oxide nanofibers can be a suitable replacement for routine wound coverages. Hence, this study was conducted to present a combination of these methods.Materials and Methods: Chitosan/polyethylene oxide nanofibers and thin films of chitosan were produced and optimized by electron microscopy, on which the bone marrow stromal cells were then cultivated. Interactions between the cells and these biomaterials were investigated through viability, morphology, immunocytochemistry and electron microscopy of cells after 6 days. All data were analyzed using Student’s t-test and one-way ANOVA tests in SPSS version 16. PResults: It seems that the high viscosity of chitosan prevents the formation of nanofibers, while chitosan/polyethylene oxide solutions with 80/20 and 90/10 ratios produce perfect, regular, bead free and non-toxic nanofibers with average diameter of 240±10 and 220±10 nm, respectively. The results of immunocytochemistry and viability showed that the cells had relatively high proliferation on the thin chitosan membranes, while the results of the electron microscopy showed that the morphology of cells was better on the nanofibers than on the thin membrane of chitosan.Conclusion: Since bone marrow stromal cells were grown well on chitosan-nanofibers, each of them alone was used in the therapeutic methods. It is better to consider a combination of two methods as the treatment method, especially in tissue engineering and cell therapy.
Surface-active substance monolayer stability after its formation

The effect of different concentrations of K+, Na+, Ca2+, Ni2+, Al3+ and Fe3+ ions on surface-active substance monolayer stability has been studied using molecular mechanics method. For numerical calculations, energy potential Amber was used. Arachidic acid was chosen as a surface-active substance for monolayer formation because it is insoluble in water at normal conditions. Energy stability values representing system stability was calculated for different ion concentrations. It is established that the most stable system is formed by trivalent metal ions and that system stability decreases together with ionic charge. For each type of ions, a concentration value corresponding to most optimal stability was found with further increase of ion concentration leading to decrease of stability.
Calculation and compilation of the unsteady-lift functions for a rigid wing subjected to sinusoidal gusts and to sinusoidal sinking oscillations

The total lift responses to sinusoidal sinking oscillations and to sinusoidal gusts have been calculated, largely from existing information, for wings of various plan forms in subsonic and supersonic flow. For most of the cases considered, closed-form expressions are given and the final results are presented in the form of plots of the square of the modulus of the lift coefficient for wings in a sinusoidally oscillating gust field and in the form of the real and imaginary parts of the lift coefficient for wings undergoing sinusoidal sinking oscillations.
Transmission Line based Envelope Amplifier for Envelope Tracking in PA Systems

The aim of this thesis was to investigate the possibility of using a transmission line (TL) based converter as an envelope amplifier (EA) for envelope tracking in a radio frequency power amplifier (RF PA) system. A TL based EA can supply fast voltage modulation but requires impedance match between the characteristic impedance of the TL, and the PA’s supply terminal impedance (STI). Hence, a first step in this thesis was to investigate the characteristics of the PA’s STI. A second step was to construct a prototype of an EA, using a lumped transmission line as energy accumulator. The EA was then tested together with the PA in order to draw further conclusions whether a TL based EA is suitable for ET of PA systems. The result from the PA characterization provided two descriptions of the STI. However, the EA prototype was designed after the STI description that seemed to enable a beneficial ET operation. Despite the PA characterization it was, and still is, a bit unclear what features of the STI a pulsed supply voltage would excite during an EA to PA integration. However, the result from the integration indicated a non beneficial STI behavior. The conclusion from this report is that the studied inverse class F GaN PA does not seem to be suitable for ET with a TL based EA.
The strategies of Polish immigrant women in their search for entry into the professional labour market in Canada

This paper explores strategies of five Polish immigrant women in their search to enter the professional labour market in Canada. This study focuses on the most effective methods these women utilized in order for them to become successful. This study found that, despite their challenges and experiences, their way to success was strongly influenced by four main strategies they used to overcome these barriers. These are: use of Canadian government and other employment services/programs; networking within own ethnic community; improving their proficiency in English; and perseverance in the process of search for employment in Canada. This major research paper shows that there is much to learn from the strategies used by these Polish professional immigrant women for entering the professional labour market in Canada. The results will be presented in the form of research implications and practical applications for policy-makers, non-governmental organizations, and researchers.
Formulation of green nano-fertilizer to enhance the plant growth through slow and sustained release of nitrogen.

Fertilizers are chemical compounds applied to promote plant growth. It is applied either through the soil or by foliar feeding. Artificial fertilizers are inorganic fertilizers formulated in appropriate concentration to supply the nutrients. Nitrogen is an important source which is essential for the growth of plant. Urea is the most widely used water soluble plant nitrogen source. Due to leaching the nitrogen content in the soil gets decreased due to leaching. So NUE (Nitrogen utilization efficiency) is low. Urea modified hydroxyapatite particles have been employed to agriculture, because of their higher NUE and slow release of the nitrogen to the soil. These maximize the NUE utilization by plants and minimize the adverse effects to the environment. Hydroxyapatite was prepared using chemical combination of ortho phosphoric acid and calcium hydroxide. Then prepared colloidal hydroxyapatite was kept in refrigerator for overnight. Powdered hydroxyapatite molecule was prepared in different concentration (10%, 20%, 30% and 40%) and was mixed with nanourea molecule using ultrasonicator. Urea modified composite molecule was applied to the field green gram (Vigna radiata) as both seed treated and directly applied to soil. Urea modified HA particle has the highest pH of 7.81 compared to that of normal urea. Seed germination was observed in all the pot. HA particle treated seed shows the good germination of 100% towards the yield whereas urea alone gives only 70% of seed germination. Height of the plant clone of HA treated as 11.8cm for 5days time interval in contrast Urea alone treated has only 10cm and density also low compared to HA treat. Nitrogen release was estimated by using nitrate estimation. Nitrate estimation of HA particle was calculated as 100μg/ml whereas urea treated was calculated as 50μg/ml. In this context, we concluded that Hydroxyapatite molecule shows the good utilization of nitrogen source. So it has the better yield than other conventional fertilizer.
