Control and Estimation of Asynchronous Machines Using Fuzzy Logic

These techniques are traditionally solved using a mathematical model of the machine with fixed parameters. However, in a real machine, the stator and rotor resistances are altered by temperature and the inductances are altered by the magnetizing current values that change for example when the machine is running in the flux weakening region or by an improper detuning between the flux and torque producing currents. For these reasons, the induction machine shows properties of nonlinear and time-varying systems. Parameter variations degrade the system performance over the full range of motor operation and in extreme conditions this can lead to instability (Vas, 1999). To solve this problem the controller parameters have to be continuously adapted. This adaptation can be achieved using different techniques such as MRAC or model reference adaptive control (Zhen & Xu, 1998), sliding mode (Won & Bose, 1992), or self tuning PIDs (Astrom & Hagglung, 1996). For some of these techniques the motor parameters and load inertia must be calculated in real time, so there is a high processing requirement for the used processors.
Theorizing the Father-Child Relationship: Mechanisms and Developmental Outcomes

The aim of this article is to propose a theorization of the father-child relationship based on our current understanding of attachment, interactions between fathers and their young children, and human-specific adaptations. The comparison of mother-child and father-child interactions suggests that fathers play a particularly important role in the development of children’s openness to the world. Men seem to have a tendency to excite, surprise, and momentarily destabilize children; they also tend to encourage children to take risks, while at the same time ensuring the latter’s safety and security, thus permitting children to learn to be braver in unfamiliar situations, as well as to stand up for themselves. But this dynamic can only be effective in the context of an emotional bond between father and child; this relationship is termed the father-child activation relationship, in contrast to the mother-child attachment relationship aimed at calming and comforting children in times of stress. The activation relationship is developed primarily through physical play. It is postulated, in particular, that father-child rough-and-tumble play encourages obedience and the development of competition skills in children.
Neural correlates of attention and memory in the first year of life

Our understanding of the neural correlates involved in the development of attention and memory has lagged behind our knowledge of the behavioral manifestation of these abilities. This is unfortunate, as a more complete account of the brain bases for these aspects of development would likely contribute to a more thorough understanding of cognitive development in general. In this article we review previous studies from our laboratory examining recognition memory in 4‐, 6‐, and 8‐month‐old infants, and then describe more recent work with 12‐month‐old infants. From these data we conclude that the development of recognition memory lags behind that of attention. Specifically, by 4 months infants show event‐related potential (ERP) evidence of selectively attending to stimuli presented as briefly as 100 msec. Infants this same age are also able to distinguish a single novel stimulus from a single familiar stimulus. By 6 months, infants begin to distinguish between frequently and infrequently presented events, and.
Digital vs. Print: Reading Comprehension and the Future of the Book

The future of books and libraries is put into question by the increasing popularity of e-books and the use of computers as text platforms. In an effort to anticipate which reading platform—print, e-readers, or computers displays—will dominate in the coming years, recent research and experimental data on the suitability of each reading platform for reading comprehension will be considered, from the perspectives of optical issues, cognition, and metacognition. It will be shown that, while printed books are most conducive to learning from longer, more difficult texts, e-readers and computer displays offer convenience and some distinct advantages to readers in particular situations. This synthesis of current research will be helpful to librarians working in digital and print book purchasing and collection development, as well as those making long-range planning decisions.
Coprocytobiology: On the Nature of Cellular Elements from Stools in the Pathophysiology of Colonic Disease

Abstract The gastrointestinal epithelium is known to undergo constant and rapid renewal resulting in millions of cells being shed into the fecal stream every day. The conventional wisdom was that these cells disintegrate upon exfoliation and will not survive the transit through the intestinal tract. In 1990, we (P.N.) made the discovery that a significant number of these cells remain intact and viable and that they can be isolated. The implications of this important discovery became apparent when we demonstrated that these cells are exclusively of colonic origin, are anatomically representative of the entire colon, and can be used for clinical investigations of disease processes. The term coprocytobiology (CCB) was coined to encompass the broad range of applications of this new technology. The somatic cell sampling and recovery (SCSR) process involves the isolation of exfoliated colonocytes from a small sample of stool (≈1 g) collected and transported in a unique medium at ambient temperature, providing cells for the detection of a number of biomarkers of disease propensity. These exfoliated colonocytes express cytokeratins indicating epithelial lineage as well as colon‐specific antigen. Over the years, the study of exfoliated colonocytes has provided striking new insights into the biology of colon cancer and inflammatory bowel disease, including detection of p53 gene mutations, reverse transcriptase polymerase chain reaction amplification, and identification of CD44 splice variants, neoplasia‐associated specific binding of plant lectins, and expression of COX‐2, the inducible form of cyclooxygenase. The functional diversity of cells isolated by SCSR is revealed by the demonstration of cell surface markers such as secretory component, IgA, and IgG on the one hand and the amplification and cloning of the human insulin receptor and the expression of the multidrug resistance gene mdr‐1 on the other hand. This review portrays the immense potential of CCB as a powerful tool for investigating the pathophysiology of disease, identifying genetic variants in pharmacogenetics, assessment of mucosal immunity, and several other applications that use somatic cells.
Group-Induced Polarization in Simulated Juries

Group-induced shift effects observed on other response dimensions were extended to a simulated jury setting. Subjects first responded to eight hypothetical traffic cases which varied in the implication of guilt (high or low), then discussed half of these cases (two high guilt and two low guilt) in small groups, and finally responded again to all eight cases. As predicted, the simulated jury deliberations polarized the mean judgment of discussed cases. After discussing low guilt cases, subjects were, on the average, more extreme in their judgments of innocence and more lenient in recommended punishment, and after discussing high guilt cases shifted toward harsher judgments of guilt and punishment. These effects were not observed for cases which were not discussed.
Characteristics of the Synchronization of Brain Activity imposed by Finite conduction Velocities of axons

The electrical activity of neurons in brains fluctuates erratically both in terms of pulse trains of single neurons and the dendritic currents of populations of neurons. Obviously the neurons interact with one another in the production of intelligent behavior, so it is reasonable to expect to find evidence for varying degrees of synchronization of their pulse trains and dendritic currents in relation to behavior. However, synaptic communication between neurons depends on propagation of action potentials between neurons, often with appreciable distances between them, and the transmission delays are not compatible with synchronization in any simple way. Evidence is on hand showing that the principal form of synchrony is by establishment of a low degree of covariance among very large numbers of otherwise autonomous neurons, which allows for rapid state transitions of neural populations between successive chaotic basins of attraction along itinerant trajectories. The small fraction of covariant activity is extracted by spatial integration upon axonal transmission over divergent–convergent pathways, through which a remarkable improvement in signal-to-noise ratio is achieved. The raw traces of local activity show little evidence for synchrony, other than zero-lag correlation, which appears to be largely a statistical artifact. Brains rely less on tight phase-locking of small numbers of periodically firing neurons and more on low degrees of cooperativity achieved by order parameters influencing very large numbers of neurons. Brains appear to be indifferent to and undisturbed by widely varying time and phase relations between individual neurons and even large semi-autonomous areas of cortex comprising their mesoscopic neural masses.
Kinetic Rate Constant Prediction Supports the Conformational Selection Mechanism of Protein Binding

The prediction of protein-protein kinetic rate constants provides a fundamental test of our understanding of molecular recognition, and will play an important role in the modeling of complex biological systems. In this paper, a feature selection and regression algorithm is applied to mine a large set of molecular descriptors and construct simple models for association and dissociation rate constants using empirical data. Using separate test data for validation, the predicted rate constants can be combined to calculate binding affinity with accuracy matching that of state of the art empirical free energy functions. The models show that the rate of association is linearly related to the proportion of unbound proteins in the bound conformational ensemble relative to the unbound conformational ensemble, indicating that the binding partners must adopt a geometry near to that of the bound prior to binding. Mirroring the conformational selection and population shift mechanism of protein binding, the models provide a strong separate line of evidence for the preponderance of this mechanism in protein-protein binding, complementing structural and theoretical studies.
Colonization of high-elevation lakes by long-toed salamanders (Ambystoma macrodactylum) after the extinction of introduced trout populations

We surveyed high-elevation lakes for long-toed salamander (Ambystoma macrodactylum) larvae and trout in the northern Bitterroot Mountains of Montana, U.S.A. , in 1978, 1997, and 1998. Our objectives were to (i) test whether trout exclude salamander populations; (ii) determine whether lakes in which trout have gone extinct have since been colonized by salamanders; and (iii) estimate the rates of population extinction and colonization in lakes never stocked with trout. In agreement with previous work on the interactions between trout and long-toed salamanders, trout effectively excluded salamander populations from lakes. Somewhat surprisingly, however, salamanders managed to colonize lakes after the extinction of trout populations despite evidence of low levels of interpopulation dispersal in these salamander populations. In lakes never stocked with trout there was no evidence of a decline in salamander populations; 2 of these lakes were colonized and no populations went extinct.
The Moderating Effect of Travel Experience in a Destination on the Relationship Between the Destination Image and the Intention to Revisit

This article is the first outcome of a two-part study examining American college students' perceptions of South Korea as a travel destination. The study, as a whole, verifies whether students' destination image formation is affected differently by their travel experience in a destination. In other words, this article investigates whether students' travel experience during college reinforces their image formation in a destination and affects their future travel decision making and choices. A total of 770 valid questionnaires were collected from 4-year educational institutions in the United States through an online survey. Factor analysis and hierarchical multiple regression were used to determine the moderating effect of travel experience to a destination on the relationship between the destination image and the intention to revisit. The results of this study showed that the travel experience reinforced individuals' image of a destination collectively and positively affected the intention to revisit; however, findings revealed that students' travel experience at the destination has negatively influenced on their image if it is related to the cultural factor.
Suppression of Flicker Noise Up-Conversion in a 65-nm CMOS VCO in the 3.0-to-3.6 GHz Band

Flicker noise up-conversion in voltage-biased oscillators can be effectively suppressed by inserting resistances in series to the drain of the transconductor MOSFETs. This solution avoids the degradation of the start-up margin and the adoption of area-demanding resonant filters with proper tuning. This paper presents a detailed theoretical analysis of 1/f noise up-conversion and quantitatively addresses the impact of two major contributions, namely the Groszkowski effect and the loop delay caused by stray capacitances at the drain node of the transistors. A simple flow for the design of an oscillator with suppressed flicker noise up-conversion is presented which is based on first-order closed-form formulas. Finally , theoretical estimates are compared to experimental results on a 65-nm CMOS VCO covering the 3.0-3.6 GHz band.
Stochastic Geometric Coverage Analysis in mmWave Cellular Networks with a Realistic Channel Model

Millimeter-wave (mmWave) bands have been attracting growing attention as a possible candidate for next- generation cellular networks, since the available spectrum is orders of magnitude larger than in current cellular allocations. To precisely design mmWave systems, it is important to examine mmWave interference and SIR coverage under large-scale deployments. For this purpose, we apply an accurate mmWave channel model, derived from experiments, into an analytical framework based on stochastic geometry. In this way we obtain an analytical expression for the SIR coverage probability in mmWave cellular networks.

Multiple snapshot Beamspace Matrix Pencil method for direction of arrival estimation

Beamspace Matrix Pencil (BMP) method is a recently developed method which estimates Direction of Arrival (DOA) of plane wave signals in a computationally efficient way by utilizing a priori information in the form of rough estimate of DOA. However, in multiple snapshot scenarios its computational advantage over other matrix pencil methods is decreased. In this paper, we propose a Multiple Snapshot Beamspace Matrix Pencil (MSBMP) method which not only uses a priori information about DOA but also utilizes the frequency information (i.e. often available in sonar/radar applications). Consequently, the computational cost is further decreased without compromising the performance.
Direct binding targets of the stringent response alarmone (p)ppGpp

The Escherichia coli stringent response, mediated by the alarmone ppGpp, is responsible for the reorganization of cellular transcription upon nutritional starvation and other stresses. These transcriptional changes occur mainly as a result of the direct effects of ppGpp and its partner transcription factor DksA on RNA polymerase. An often overlooked feature of the stringent response is the direct targeting of other proteins by ppGpp. Here we review the literature on proteins that are known to bind ppGpp and, based on sequence homology, X‐ray crystal structures and in silico docking, we propose new potential protein binding targets for ppGpp. These proteins were found to fall into five main categories: (i) cellular GTPases, (ii) proteins involved in nucleotide metabolism, (iii) proteins involved in lipid metabolism, (iv) general metabolic proteins and (v) PLP‐dependent basic aliphatic amino acid decarboxylases. Bioinformatic rationale is provided for expanding the role of ppGpp in regulating the activities of the cellular GTPases. Proteins involved in nucleotide and lipid metabolism and general metabolic proteins provide an interesting set of structurally varied stringent response targets. While the inhibition of some PLP‐dependent decarboxylases by ppGpp suggests the existence of cross‐talk between the acid stress and stringent response systems.
Comparison of two different rest intervals on drop jump: effects on muscle damage markers

Comparison of two different rest intervals on drop jump: effects on muscle damage markers Study aim: To determine the effects of 60- or 180-s rest intervals between sets of drop jump (DJ) exercise on serum creatine kinase (CK) activity and perceived muscle soreness. Materials and methods: A group of 36 healthy male subjects aged 18 - 19 years performed 4 sets of 10 DJ, the rest intervals between sets amounting to 60 (Group A) or 180 s (Group B). Before, as well as 3, 24, 48, and 72 h post-exercise, blood was sampled for determining the activity of in serum CK activity and the perceived muscle soreness was reported. Two-way ANOVA (time x rest interval) was used in data analysis. Results: The DJ sessions induced muscle soreness and elevated serum CK activity (p<0.05). No significant between-group differences were found. Conclusion: Rest intervals of 1 - 2 min duration had no effect on the magnitude of changes in CK activity or perceived muscle soreness. This may be of practical importance when designing training which includes drop jumps.
An Organic/Inorganic Hybrid Membrane as a Solid “Turn-On” Fluorescent Chemosensor for Coenzyme A (CoA), Cysteine (Cys), and Glutathione (GSH) in Aqueous Media

The preparation of a fluorogenic sensory material for the detection of biomolecules is described. Strategic functionalisation and copolymerisation of a water insoluble organic sensory molecule with hydrophilic comonomers yielded a crosslinked, water-swellable, easy-to-manipulate solid system for water “dip-in” fluorogenic coenzyme A, cysteine, and glutathione detection by means of host-guest interactions. The sensory material was a membrane with gel-like behaviour, which exhibits a change in fluorescence behaviour upon swelling with a water solution of the target molecules. The membrane follows a “turn-on” pattern, which permits the titration of the abovementioned biomolecules. In this way, the water insoluble sensing motif can be exploited in aqueous media. The sensory motif within the membrane is a chemically anchored piperazinedione-derivative with a weakly bound Hg(II). The response is caused by the displacement of the cation from the membrane due to a stronger complexation with the biomolecules, thus releasing the fluorescent sensory moieties within the membrane.
Changes in Visual Object Recognition Precede the Shape Bias in Early Noun Learning

Two of the most formidable skills that characterize human beings are language and our prowess in visual object recognition. They may also be developmentally intertwined. Two experiments, a large sample cross-sectional study and a smaller sample 6-month longitudinal study of 18- to 24-month-olds, tested a hypothesized developmental link between changes in visual object representation and noun learning. Previous findings in visual object recognition indicate that children’s ability to recognize common basic level categories from sparse structural shape representations of object shape emerges between the ages of 18 and 24 months, is related to noun vocabulary size, and is lacking in children with language delay. Other research shows in artificial noun learning tasks that during this same developmental period, young children systematically generalize object names by shape, that this shape bias predicts future noun learning, and is lacking in children with language delay. The two experiments examine the developmental relation between visual object recognition and the shape bias for the first time. The results show that developmental changes in visual object recognition systematically precede the emergence of the shape bias. The results suggest a developmental pathway in which early changes in visual object recognition that are themselves linked to category learning enable the discovery of higher-order regularities in category structure and thus the shape bias in novel noun learning tasks. The proposed developmental pathway has implications for understanding the role of specific experience in the development of both visual object recognition and the shape bias in early noun learning.
Dobzhansky: 40 Years Later Nothing Makes Sense

Forty years ago Theodosius Dobzhansky, a scientist credited with developing the reigning paradigm of neo-Darwinism, published his iconic article with the famed title, “Nothing in Biology Makes Sense Except in the Light of Evolution. ” The intervening decades have seen his three predictions falsified; namely those regarding genetics and the tree of life, the role evolution theory would play in the progress of biological science, and one particular Arab sheik whom Dobzhansky identified by name. Dobzhanky’s claims are evaluated in the light of four decades of hindsight, much additional scientific research, and the continued development of the creation model. His arguments regarding the diversity of life, biological universals, and abiogenesis are answered in a point-by-point presentation.
Travel as interaction: encountering place and others

This article examines ‘encounters’, or interactions between tourists. The focus is on how social life is established and maintained, specifically the meaning of inter-tourist social interactions in the remote regions of Australia. The ways in which perceptions of the landscape frame these interactions are also considered. The meaning and significance of these interactions was found to be filtered through the prism of the tourists' occupation of a physically demanding, sometimes threatening and culturally unfamiliar landscape. Because of the rigours of the travel environment, tourists were keen to be in the company of others, but in encounters or relationships free of the obligation of ongoing attachment, without specific function, content or outcome. Their interactions with other tourists and the local populations enriched their understanding of the social and physical environment. Those interactions offered comfort and companionship in what they perceived to be a hostile and alien environment.
