A fast counting method for generic order intermodulation products

Nonlinear devices such as amplifiers and electro-optical transducers introduce spurious signals known as intermodulations, especially when multiple signals at different frequencies access the system. In this paper an extension to the well known fast counting algorithm (FCA) for the intermodulations is presented and a comparison with slow counting algorithms is done. Carrier configuration is represented by means of indicator polynomials, and high-order Intermodulation products distribution can be computed in a fast way, extending the results restricted to third order intermodulations. Moreover, no particular assumption is done on the distribution of the carriers (i.e. they are not required to be equispaced). Comparisons are made in terms of accuracy and speed with slow direct counting algorithms.
Cluster analysis of Canonical Correlation coefficients for the SSVEP based brain-computer interfaces

In this paper, a novel method for detecting steady-state visual evoked potentials (SSVEP) using multiple channel electroencephalogram (EEG) data is presented. Accurate asynchronous detection, high speed and high information transfer rate can be achieved after a short calibration session. Spatial filtering based on the Canonical Corelation Analysis method proposed in [1] is used for identifying optimal combinations of electrode signals that cancel strong interference signals in the EEG. Data from a test group consisting of 21 subjects are used to evaluate the new methods and to compare results to standard spectrum analysis approach. Conducted research, for different length signal segments and five visual frequencies, showed improvement of both classification accuracy and detection speed.
Collocations of Complex Nouns : Evidence for Lexicalisation

This paper combines a corpus-based study of noun+verb collocations with an attempt to distinguish compositional, regularly formed compounds from lexicalised ones. We claim that morphologically regular, compositional compounds share most of their collocational preferences with their compound heads, whereas lexicalised compounds have their own collocational preferences, distinct or only marginally overlapping with those of their heads. We test this claim on corpus data for noun+verb collocations of 85 German simple nouns and their compounds (1,058 types). The extraction relies on stochastic parsing, since this procedure provides syntactically homogeneous data and frequency counts, which are input to the log-likelihood association measure, to compute significance scores for the combinations. The experiments seem to confirm our hypothesis: a collocational analysis of this kind can serve to identify lexicalised compounds. Being able to identify lexicalised compounds is relevant for lexicography in different respects: in the definition of the nomenclature of a dictionary, because lexicalised compounds should be included with priority, and in work on the micro structure, because collocations of a compound which are shared with the compound head may be treated extensively under the head, with only a reference or a pointer under the compound.
In vitro transfection of anti-tumor miR-101 induces BIM, a pro-apoptotic protein, expression in acute myeloid leukemia (AML)

Acute myeloid leukemia (AML) frequently relapses after initial treatment, though it is possible that drug resistance occurs. Hence, it seems necessary to develop novel therapies such as gene therapy specifically via miRNA transfection. MicroRNA-101 has been considered as a tumor suppressor in different types of cancer. It is demonstrated that exogenous miR-101 transfection is associated with decreased viability in AML in this paper. Besides, the increase of pro-apoptotic protein BIM expression in both mRNA and protein level has been illustrated. The recent findings provide an insight into the novel function of miR-101 in AML by activating BIM as an important mediator in intrinsic apoptosis pathways. Generally, miR-101 has been considered as a therapeutic target in our data and might have a valuable role in AML.
A Theory of Information Genetics: How Four Subforces Generate Information and the Implications for Total Quality Knowledge Management

This essay proposes a model called information genetics (IG) to elaborate on the origin of information generating. The model builds on a broad information generating force that is both cause and effect. Part I of this essay postulates this information generating force as the result of the interaction and intermediation among four subforces: Query, command, statement, and term-term bond. These subforces are described by a process called twisting-bonding/clipping-jointing. The effect of this process is elaborated by: (1) Analyzing the Information Generating Model (IGM); (2) Transfiguring the Mobius Strip into the Mobius Twist Model; and (3) Demonstrating the process of the Clipping-Jointing Model. These three models are defined, exemplified, and described in detail. In Part II, a Fuzzy Commonality Model (FCM) is introduced to describe and explain the formation of a network curvature and to measure the dynamics of the twisting-bonding/ clipping jointing process within any special subject information field. In Part III, a software program is developed through the FCM for citation data mining, infomapping, and information repackaging -the three key elements in total quality knowledge management (TQKM). The conceptual and data models are supported by practical examples and statistical data. Several information flows are displayed in parallel to show their twisting-bonding/clipping-jointing interaction and intermediation relationships. This paper discusses the significance and advantages of the information genetics models and their approachability and applicability for TQKM in infomapping and Web information representation. The meaning of the information genetics models is also examined from a global perspective.
Optimizing the rate of a correlated MIMO link jointly over channel estimation and data transmission parameters

We consider a single-user correlated MIMO channel with block fading, where each block is divided into training and data transmission phases. The receiver has a noisy CSI that it obtains through a channel estimation process, while the transmitter has partial CSI in the form of covariance feedback. We optimize the achievable rate jointly over the parameters of the training and data transmission phases. In particular, we first choose the training signal to minimize the channel estimation error, and then, develop an iterative algorithm to solve for the optimum training duration, the optimum allocation of power between training and data transmission phases, and the optimum allocation of power over the antennas during the data transmission phase.
Differential Evolution based Optimal Control of Induction Motor Serving to Textile Industry

This paper illustrates the importance of controllers on energy saving opportunity of partial loaded three-phase induction motor in textile mill (ring spinning frame) applications. The economics of a scalar controlled 100 HP induction motor is investigated with three topologies namely star-delta (S/D) connection, constant Volt/frequency (V/f) controller and Differential Evolution (DE) controller in steady-state conditions. In this study, the flux level in a machine has been considered to adjust to give minimum operating cost for the textile mill load. The flux controller improves the economics in terms of operating cost (energy cost and demand charge cost) and the test results show that the flux level in the most economic motor will be adjusted according to load and speed, particularly at light load. Standard benchmark problems (Rastingin and Griewank) have been considered for validation of the proposed DE controller for induction motor operating cost minimization. Case study also presented in this paper.
Nck-Interacting Ste20 Kinase Couples Eph Receptors to c-Jun N-Terminal Kinase and Integrin Activation

ABSTRACT The mammalian Ste20 kinase Nck-interacting kinase (NIK) specifically activates the c-Jun amino-terminal kinase (JNK) mitogen-activated protein kinase module. NIK also binds the SH3 domains of the SH2/SH3 adapter protein Nck. To determine whether Nck functions as an adapter to couple NIK to a receptor tyrosine kinase signaling pathway, we determined whether NIK is activated by Eph receptors (EphR). EphRs constitute the largest family of receptor tyrosine kinases (RTK), and members of this family play important roles in patterning of the nervous and vascular systems. In this report, we show that NIK kinase activity is specifically increased in cells stimulated by two EphRs, EphB1 and EphB2. EphB1 kinase activity and phosphorylation of a juxtamembrane tyrosine (Y594), conserved in all Eph receptors, are both critical for NIK activation by EphB1. Although pY594 in the EphB1R has previously been shown to bind the SH2 domain of Nck, we found that stimulation of EphB1 and EphB2 led predominantly to a complex between NIK/Nck, p62 dok , RasGAP, and an unidentified 145-kDa tyrosine-phosphorylated protein. Tyrosine-phosphorylated p62 dok most probably binds directly to the SH2 domain of Nck and RasGAP and indirectly to NIK bound to the SH3 domain of Nck. We found that NIK activation is also critical for coupling EphB1R to biological responses that include the activation of integrins and JNK by EphB1. Taken together, these findings support a model in which the recruitment of the Ste20 kinase NIK to phosphotyrosine-containing proteins by Nck is an important proximal step in the signaling cascade downstream of EphRs.
HEALTH AND DEMOGRAPHIC SURVEILLANCE SYSTEM PROFILE Profile: The Kilifi Health and Demographic Surveillance System (KHDSS)

The Kilifi Health and Demographic Surveillance System (KHDSS), located on the Indian Ocean coast of Kenya, was established in 2000 as a record of births, pregnancies, migration events and deaths and is maintained by 4-monthly household visits. The study area was selected to capture the majority of patients admitted to Kilifi District Hospital. The KHDSS has 260 000 residents and the hospital admits 4400 paediatric patients and 3400 adult patients per year. At the hospital, morbidity events are linked in real time by a computer search of the population register. Linked surveillance was extended to KHDSS vaccine clinics in 2008. KHDSS data have been used to define the incidence of hospital presentation with childhood infectious diseases (e.g. rotavirus diarrhoea, pneumococcal disease), to test the association between genetic risk factors (e.g. thalassaemia and sickle cell disease) and infectious diseases, to define the community prevalence of chronic diseases (e.g. epilepsy), to evaluate access to health care and to calculate the operational effectiveness of major public health interventions (e.g. conjugate Haemophilus influenzae type b vaccine). Rapport with residents is maintained through an active programme of community engagement. A system of collaborative engagement exists for sharing data on survival, morbidity, socio-economic status and vaccine coverage.
Joint Codebook Design for Multi-cell Noma

For spreading-based multiple access, whether orthogonal (OMA) or non-orthogonal (NOMA), the spreading sequences (signatures) are selected from a predefined codebook. When operating in a cellular system, intercell interference will be inherently present between close base stations that share the same resources. If the codebook is reused across the different cells, then intercell interference can cause a full collision of the interfering users in the code-domain, thus deteriorating their performance, especially those at the cell-edge. In this paper, we propose a method for reducing intercell interference by means of jointly designed codebooks. The criterion for the code-book design is to minimize the maximum cross-correlation between the signatures of the interfering cells. In order to obtain such code-books, we employ the algorithm of alternating projection. We finally apply the method to two interfering cells for both NOMA and OMA systems, with the users being uniformly distributed in the cells, and show that it can provide a considerable gain to the cell-edge users.
A reassessment of the factors affecting microtubule assembly and disassembly in vitro.

Current models of microtubule assembly from pure tubulin involve a nucleation phase followed by microtubule elongation at a constant polymer number. Both the rate of microtubule nucleation and elongation are thought to be tightly influenced by the free GTP-tubulin concentration, in a law of mass action-dependent manner. However, these basic hypotheses have remained largely untested due to a lack of data reporting actual measurements of the microtubule length and number concentration during microtubule assembly.Here, we performed simultaneous measurements of the polymeric tubulin concentration, of the free GTP-tubulin concentration, and of the microtubule length and number concentration in both polymerizing and depolymerizing conditions. In agreement with previous work we find that the microtubule nucleation rate is strongly dependent on the initial GTP-tubulin concentration. But we find that microtubule nucleation persists during microtubule elongation. At any given initial tubulin-GTP concentration, the microtubule nucleation rate remains constant during polymer assembly, despite the wide variation in free GTP-tubulin concentration. We also find a remarkable constancy of the rate of microtubule elongation during assembly. Apparently, the rate of microtubule elongation is intrinsic to the polymers, insensitive to large variations of the free GTP-tubulin concentration. Finally we observe that when, following assembly, microtubules depolymerize below the free GTP-tubulin critical concentration, the rate-limiting factor for disassembly is the frequency of microtubule catastrophe. At all time-points during disassembly, the microtubule catastrophe frequency is independent of the free GTP-tubulin concentration but, as the microtubule nucleation rate, is strongly dependent on the initial free GTP-tubulin concentration. We conclude that the dynamics of both microtubule assembly and disassembly depend largely on factors other than the free GTP-tubulin concentration. We propose that intrinsic structural factors and endogenous regulators, whose concentration varies with the initial conditions, are also major determinants of these dynamics.
Association between venous thromboembolism and perioperative allogeneic transfusion.

HYPOTHESIS Perioperative allogeneic blood product transfusion would be associated with venous thromboembolic complications in surgical patients. DESIGN Observational study using a state discharge database. SETTING Nonfederal acute care hospitals in Maryland performing colorectal cancer resections between January 1, 1994, and December 31, 2000. PATIENTS We obtained data on 14 014 adult patients having a primary diagnosis code for colorectal cancer and a primary procedure code for colorectal resection. MAIN OUTCOME MEASURES The primary outcome variable was a discharge diagnosis of venous thromboembolism (VTE). RESULTS Venous thromboembolism occurred in 1% of patients and was associated with an adjusted 3.8-fold increase in mortality (odds ratio, 3.8; 95% confidence interval, 2.1-6.8), a 61% increase in mean hospital length of stay, and a 72% increase in mean total hospital charges. Risk factors for VTE after adjustment included transfusion, female sex, age 80 years or older, moderate to severe liver disease vs no liver disease, admission through the emergency department, and low annual surgeon case volume. Transfusion was associated with an increase in the odds of developing VTE in women (odds ratio, 1.8; 95% confidence interval, 1.2-2.6) but not in men (odds ratio, 0.9; 95% confidence interval, 0.5-1.9). In the absence of transfusion, female compared with male sex was not associated with an increased risk of VTE (odds ratio, 1.2; 95% confidence interval, 0.8-1.7). CONCLUSIONS In this large observational study of patients undergoing colorectal cancer resection, perioperative allogeneic blood transfusion was associated with an increased risk of VTE in women but not in men. Given the substantial morbidity and mortality associated with VTE and the implication that this finding has for postoperative management in women, this association must be confirmed in independent studies.
Formation Tracking Control using Virtual Structures and Deconfliction

The work in this paper addresses an approach to 3D formation tracking control based on virtual structures. In this approach, the virtual structure specifies the formation position of each vehicle, and virtual leaders are constructed ahead of each position for the vehicles to follow. The velocity of the virtual structure is assumed to be piecewise-constant to provide zero steady-state error. In order to prevent transients from leading to collisions, deconfliction techniques are applied. Analysis of stability and performance is given, and results are demonstrated in simulation
It's a Boy Thing: The Role of the Internet in Young People's Psychological Wellbeing

Abstract The aim of this study was to assess the relationship between psychological wellbeing and Internet use among adolescents, focussing not only on time spent on the Internet, but also on the relative strength/importance of both face-to-face and Internet friendship networks. A sample of 336 young people aged between 15 and 21 years from a secondary school and a university population were surveyed. Results indicated that females with more online friends were higher on selfesteem and lower on loneliness than females with fewer online friends, but the opposite was true for males. A higher number of online regular friendships seemed to militate against self-esteem and was related to greater loneliness for males. For face-to-face friendships, the effects on wellbeing were in the same direction for males and females, but stronger for males. Those with more face-to-face friendships were higher on self-esteem and less lonely. In addition, young men who rated their online friendship networks as very important were more likely to have lower self-esteem and to be lonely. Actual time spent on the Internet was not a predictor of wellbeing for either sex when online and offline friendship factors were included in the regression equation.
Alleviating Traffic Congestion in Prishtina

This Honor Project paper analyzes the problem of traffic congestion in Prishtina. Firstly, factors that cause traffic congestion are identified. Understanding these factors provides some clues on potential contra measures. Secondly, economic and social effects are discussed to evaluate the importance of alleviating traffic congestion. Lastly, based on the existing city models, different strategies to resolving this problem are presented. In doing so, various designing and simulation tools are used to visualize and compare different scenarios. The research methodology for this project includes literature review, site visits, an in-depth interview, and surveys. I. Chapter 1 – Problem Statement The automobile has become a predominant way of traveling nowadays. The increasing number of households along with the increasing number of cars that a household owns hastens the increasing rate of traffic delay in the urban areas (“US Department of Transportation,” 2013). This suggests that this problem is growing exponentially and it should be persistently addressed in order to avert its negative consequences. Traffic jams hinder mobility, contribute in air pollution, waste fuel, and impede economic growth (“A Toolbox for Alleviating Traffic Congestion,” 1989). Traffic congestion has become an increasing problem in Prishtina as well. This phenomenon is vastly present during the rush hours of 8 to 9 AM and 4 to 5 PM. Taking into account that it negatively influences the economic and environmental aspect of society, resolving this issues is crucial for social well-being. This project conducts a careful analysis of factors that cause traffic blockages and uses this information to come up with different techniques and strategies to improve the existing situation. II. Chapter 2 – Literature Review A. Traffic Congestion According to Institute of Transporting Engineers, traffic congestion is a situation where “there are more people trying to use a given transportation facility during a specific period of
Cooperative Robot-Drone Agents for Obstacle Avoidance using Smart Vision

- Recent advancements in robotics and computer science are pushing the boundaries of exploration and our understanding of intelligent systems. These systems have the potential to interact with one another to solve difficult tasks, such as exploring a new planet or providing emergency assistance. Our research focuses on studying the interaction between an autonomous robot and drone and how they perceive and understand the environment to perform a given task. Utilizing advanced path-planning algorithms, image processing techniques, and various sensors for localization, the robot and drone can interact with the environment to solve generic tasks, such as finding an optimal path around a series of obstacles if the path is blocked utilizing a Greedy approach. Furthermore, the system is an adaptive learning model. The drone autonomously takes off and lands following the directions from the robot, increasing battery duration while providing the robot with additional sensory information. The robot and drone are two separate intelligent systems that work together solving different tasks utilizing the same dataset for learning and interacting.
Relationship between Phenolic and Antioxidant Concentration of Humulus lupulus and Alpha Acid Content

Abstract It has been well established that beer is an excellent source of polyphenols, due in part to the contribution of xanthohumol and other compounds from hops. The intent of this study was to explore the relationship between alpha acid content, antioxidant activity, and boil time in hops. Ten hops strains with different alpha acid contents were analyzed for phenolic antioxidant content via Total Phenolic Concentration (TPC) and Ferric Reducing Antioxidant Power (FRAP) assays. Each strain was boiled for 10, 30, or 60 min, consistent with typical beer brewing protocols. Phenolic and antioxidant content increased with boil time, with Citra hops showing higher phenolic content than other strains regardless of boil time. It appears that longer boil times yield higher TPC and FRAP concentrations regardless of alpha acid content. There was a nonstatistical inverse correlation between alpha acid and phenolic content; as a result, beers that use high alpha acid hops or short boil times may have lower TPC and FRAP concentration than beers that use low alpha acid hops and long boil times.
