The Dry Sliding Wear Properties of Nano-Sized TiCp/Al-Cu Composites at Elevated Temperatures

Nano-sized ceramic particle reinforced aluminum composites exhibit excellent room-temperature mechanical properties. However, there is limited research on the dry sliding wear behavior of those composites at elevated temperatures, which should be one of the major concerns on elevated temperature applications. Here the Al-Cu composites reinforced with nano-sized TiCp were fabricated. The dry sliding wear behaviors of the nano-sized TiCp/Al-Cu composites at various temperatures (140–220 °C) and loads (10–40 N) with different TiCp contents were studied, and the results showed that the nanocomposites exhibited superior wear resistance. For instance, the relative wear resistance of the 0.5 wt. % nano-sized TiCp/Al-Cu composite was 83.5% higher than that of the Al-Cu matrix alloy at 180 °C under 20 N, and was also 16.5% higher than that of the 5 wt. % micro-sized TiCp/Al-Cu composite, attributed to the pronounced Orowan strengthening effect of nanoparticles. The wear rates of the nanocomposites were always lower than those of the Al-Cu matrix alloy under the same test condition, which increased with the increase in temperature and load and with the decrease in TiCp content.

STRATEGIC MANAGEMENT AND THE USE OF INFORMATION AND COMMUNICATION TECHNOLOGIES BY SELECTED SOUTH AFRICAN AND AMERICAN STUDENTS

This article focuses on research conducted into the value of strategy teaching and the impact of current information communication technologies (ICTs) on the business life of students in South Africa and the United States (US). The first objective of the research was to assess students' perceptions of the value of strategic management on their business life and what online practices they currently employ. The second objective was to identify students' modes of ICT access, awareness about possible ICTs, influence of sharing, submitting, amending and using information, taking time away from studies, and so forth. The third objective was to establish some differences between the two research populations in South Africa and the US. The majority of students indicated that they experience significant value in their study of strategy and there were also significant differences between the two populations about the perceived value of the ICT activities they perform.

The clinical course of unipolar major depressive disorders.

A FUNDAMENTAL paradigmatic shift is occurring in the understanding of unipolar major depressive disorders (MDD) among the general public, by many public health experts, and by the practicing psychiatric community. Most people in our society no longer view depression as a mysterious sickness of spirit or emotional weakness, but rather as a disease of the brain and an important health problem. 1 International public health experts acknowledge the high prevalence of unipolar MDD 2 combined with the pervasive human misery and impairment associated with it, and have identified this disease in 1990 as the fourth-ranked cause of disability and premature death worldwide. 3 In parallel, the treatment of unipolar MDD has evolved from incarceration, exorcism, and prayer to classic psychoanalysis, and now in the modern era to treatment with empirically proven, effective antidepressant medications and depression-specific brief psychotherapies. Meta-analyses of 6 standardized treatment studies by Thase et al 4 have
A word graph based N-best search in continuous speech recognition

The authors introduce an efficient algorithm for the exhaustive search of N-best sentence hypotheses in a word graph. The search procedure is based on a two-pass algorithm. In the first pass, a word graph is constructed with standard time-synchronous beam search. The actual extraction of N-best word sequences from the word graph takes place during the second pass. With the implementation of a tree-organized N-best list, the search is performed directly on the resulting word graph. Therefore, the parallel bookkeeping of N hypotheses at each processing step during the search is not necessary. It is important to point out that the proposed N-best search algorithm produces an exact N-best list as defined by the word graph structure. Possible errors can only result from pruning during the construction of the word graph. In a postprocessing step, the N candidates can be rescored with a more complex language model with highly reduced computational cost. This algorithm is also applied in speech understanding to select the most likely sentence hypothesis that satisfies some additional constraints.
Regulation of the Resident Chromosomal Copy of c-myc by c-Myb Is Involved in Myeloid Leukemogenesis

ABSTRACT c-myb is a frequent target of retroviral insertional mutagenesis in murine leukemia virus-induced myeloid leukemia. Induction of the leukemogenic phenotype is generally associated with inappropriate expression of this transcriptional regulator. Despite intensive investigations, the target genes of c-myb that are specifically involved in development of these myeloid lineage neoplasms are still unknown. In vitro assays have indicated that c-myc may be a target gene of c-Myb; however, regulation of the resident chromosomal gene has not yet been demonstrated. To address this question further, we analyzed the expression of c-mycin a myeloblastic cell line, M1, expressing a conditionally active c-Myb–estrogen receptor fusion protein (MybER). Activation of MybER both prevented the growth arrest induced by interleukin-6 (IL-6) and rapidly restored c-myc expression in nearly terminal differentiated cells that had been exposed to IL-6 for 3 days. Restoration occurred in the presence of a protein synthesis inhibitor but not after a transcriptional block, indicating that c-myc is a direct, transcriptionally regulated target of c-Myb. c-myc is a major target that transduces Myb's proliferative signal, as shown by the ability of a c-Myc–estrogen receptor fusion protein alone to also reverse growth arrest in this system. To investigate the possibility that this regulatory connection contributes to Myb's oncogenicity, we expressed a dominant negative Myb in the myeloid leukemic cell line RI-4-11. In this cell line, c-myb is activated by insertional mutagenesis and cannot be effectively down regulated by cytokine. Myb's ability to regulate c-myc's expression was also demonstrated in these cells, showing a mechanism through which the proto-oncogene c-mybcan exert its oncogenic potential in myeloid lineage hematopoietic cells.

The Italian American Table: Food, Family, and Community in New York City

Best Food Book of 2014 by The Atlantic Looking at the historic Italian American community of East Harlem in the 1920s and 30s, Simone Cinotto recreates the bustling world of Italian life in New York City and demonstrates how food was at the center of the lives of immigrants and their children. From generational conflicts resolved around the family table to a vibrant food-based economy of ethnic producers, importers, and restaurateurs, food was essential to the creation of an Italian American identity. Italian American foods offered not only sustenance but also powerful narratives of community and difference, tradition and innovation as immigrants made their way through a city divided by class conflict, ethnic hostility, and racialized inequalities. Drawing on a vast array of resources including fascinating, rarely explored primary documents and fresh approaches in the study of consumer culture, Cinotto argues that Italian immigrants created a distinctive culture of food as a symbolic response to the needs of immigrant life, from the struggle for personal and group identity to the pursuit of social and economic power. Adding a transnational dimension to the study of Italian American foodways, Cinotto recasts Italian American food culture as an American "invention" resonant with traces of tradition.
Competing Risks and Multistate Models

Complex clinical endpoints are present in studies in cancer. Especially in studies on hematopoietic stem-cell transplantation (HSCT), various risks exist after HSCT. Patients can experience acute and chronic graft versus host disease (GVHD) or need to undergo immunosuppressive therapy (IST), a relapse can occur, or patients can die after relapse or without former relapse (nonrelapse mortality, NRM). Sometimes, endpoints can be reasonably combined in a composite endpoint, as, for example, relapse and NRM are combined into disease-free survival (DFS). In this case, standard survival techniques, as Kaplan–Meier estimation of the DFS probability, can be applied. Often, interest focuses on endpoints for which competing risks are present, as, for example, GVHD, with death without prior GVHD as competing risk. This results in a competing risks model, a special case of a multistate model. A more complex multistate model is required when the effects of events occurring in the course of the study on further disease process shall be investigated, as, for example, the effect of GVHD on relapse and NRM. Another endpoint of interest is time under IST. As patients usually experience multiple episodes of IST, thus switching back and forth between “IST” and “no IST” during follow-up, the multistate model used for analysis must be adapted for this event structure. The aim of this nontechnical report is to explain use and interpretation of Cox-type regression models suitable for the different situations in a randomized trial on the effects of anti-T-cell globulin as GVHD prophylaxis.

EFFICIENT FITTING OF MULTIPLANET KEPLERIAN MODELS TO RADIAL VELOCITY AND ASTROMETRY DATA

We describe a technique for solving for the orbital elements of multiple planets from radial velocity (RV) and/or astrometric data taken with 1 m s−1 and μas precision, appropriate for efforts to detect Earth-massed planets in their stars' habitable zones, such as NASA's proposed Space Interferometry Mission. We include details of calculating analytic derivatives for use in the Levenberg–Marquardt (LM) algorithm for the problems of fitting RV and astrometric data separately and jointly. We also explicate the general method of separating the linear and nonlinear components of a model fit in the context of an LM fit, show how explicit derivatives can be calculated in such a model, and demonstrate the speed up and convergence improvements of such a scheme in the case of a five-planet fit to published RV data for 55 Cnc.
Prediction Outcome History-Based Confidence Estimation for Load Value Prediction

Load instructions occasionally incur very long latencies that can significantly affect system performance. Load value prediction alleviates this problem by allowing the CPU to speculatively continue processing without having to wait for the slow memory access to complete. Current load value predictors can only correctly predict about forty to seventy percent of the fetched load values. To avoid the cycle-penalty for mispredictions in the remaining cases, confidence estimators are employed. They inhibit all predictions that are not likely to be correct. In this paper we present a novel confidence estimator that is based on prediction outcome histories. Profiles are used to identify the high-confidence history patterns. Our confidence estimator is able to trade off coverage for accuracy and vice-versa with great flexibility and reaches an average prediction accuracy over SPECint95 of as high as 99.3%. Cycle-accurate pipeline-level simulations show that a simple last value predictor combined with our confidence estimator outperforms other predictors, sometimes by over 100%. Furthermore, this predictor is one of two predictors that yield a genuine speedup for all eight SPECint95 programs.
The role of social capital in negotiating socio-economic needs

This study is an investigation which focuses on the existing body of literature covering the construct of social capital and fundamental human need theories, particularly the need to understand and find meaning. It examines these in relationship to learning, culture and activity theory. The study is a preliminary investigation with limited scope. The thesis establishes an explanatory analysis and accompanying conceptual framework to be tested by further research. A proposed meth9dology for data collection and ·analysis is included. The thesis takes a humanistic approach and proposes that fundamental human need satisfaction is foundational to human well-being and growth within people's varied lifeworlds. The study reveals that human interactions and value systems connect the concepts of social capital, fundamental human need and culture in the form of activities surrounding fundamental human need satisfaction. Regarding the construct of social capital and its elements of shared values, trust, norms, reciprocity and networks, the structural, relational and cognitive dimensions of social capital are proposed and examined. This thesis suggests that the elements of the social capital construct work together to facilitate human interactions aimed at satisfying fundamental human needs across different socio-cultural systems. It places particular ~mphasis on the learning process required to negotiate the range of socio-economic need satisfactions across different cultures. Tue study also discusses theories surrounding communitarian psychology as a precursor to the introduction of activity theory. Activitxi theory in this thesis is explained as a learning model emphasising human activity aimed at the satisfaction of fundamental human needs. This thesis further develops the activity theory model to demonstrate the role social capital plays as a resource. A resource, which when accessed, acts as a mediator of human interaction aimed at enabling the satisfaction of fundamental human needs. This model directly links human values to human activity-and stresses the link between human values, human action, and the satisfaction of fundamental human needs. The model demonstrates how human values have a direct effect on how a person perceives need-satisfying activities and what resources can be accessed and used in any activity. This thesis's explanatory analysis and associated conceptual :framework give rise to a set of propositions, questions and hypotheses. The thesis underpins and justifies the significance of, and need for, a future cross-cultural study for which a methodology is proposed. This proposed future study places at its centre the importance of human values as a pivotal point around which social capital is generated and maintained.
The utility of perceptive communication between distant wireless nodes

CSMA-based MAC protocols require wireless nodes to share the transmission medium with other nodes that are within carrier-sensing (CS) range. Hence, operations that depend on and can potentially affect the state of the shared medium, such as admission control, require coordination and information sharing among these nodes. The CS range of wireless nodes is traditionally much larger than the reception range. Nodes that are outside reception range but within CS range can sense packet transmissions; however, they are unable to decode the packet contents. Direct messaging between these nodes is therefore not feasible for information sharing. In this paper, we describe two perceptive approaches for communication with nodes within CS range. Our approaches exploit the ability of a node to detect a change in the strength of the carrier signal when a transmission is in progress. Information is encoded in, and inferred from, perceptible transmission characteristics, such as the duration of a transmission or the silence between adjacent transmissions. This paper evaluates the feasibility and effectiveness of our perceptive communication mechanisms on a hardware testbed. We implement a prototype of our solution on the Mica2 mote platform and test it in different network scenarios. Our results demonstrate that the durations of transmissions and silences can be correctly detected within a small margin of error in most situations, thus verifying the utility of our approach
Analysis and design of bridged NRD-guide coupler for millimeter-wave applications

A new nonradiative-dielectric (NRD)-guide directional coupler using two NRD waveguides interconnected with a bridge is proposed and demonstrated. Propagation constants of the bridged NRD-guide couplers are investigated with an electric-field integral-equation method, and modeling results show that there is a maximum of coupling coefficient when the thickness of the bridge is made around 0.68 of the plate separation. In this case, the coupling length is reduced approximately 60% and the bandwidth under the tolerance limits of /spl plusmn/0.5 dB of deviation for 3-dB coupling is nearly doubled with reference to its conventional counterparts. The use of a bridge not only improves the mechanical stability, but also makes the coupler performance reproducible. Experimental prototypes are fabricated with two 90/spl deg/ elbow bends that are used for the arms and the bridge-connected coupler section is terminated at both ends by tapered half-circle sections. A calibration procedure is used to remove mismatch effects between the NRD-guide and the rectangular waveguide in the measured results. Advantages of the new coupler as a passive component are shown for millimeter-wave integrated circuits.
Back Away From the Lecture Notes: Using a Simulation Game to Engage Social Studies Haters

Simulation games may increase student engagement in the social studies classroom. Papert (1991) states that constructionism allows students to build, whether tangible or intangible objects, and that the building and conversation around the building allows student to learn best. In this study, the researcher observed and interviewed participants, as well as wrote in a journal about the experience, regarding playing a simulation game about the Electoral College. The researcher utilized en vivo coding to facilitate data interpretation. The participants were 18 yearold students at a suburban high school in a metropolitan area in the southeastern United States. These participants were selected by self-identifying themselves as ‘social studies haters. ’ The researcher gathered data to determine if the simulation game has a relationship to engagement in the social studies classroom and examined with the simulation game, eLECTIONS, exercised elements of the Universal Design for Learning (UDL) theory to engage the participants. The researcher determined that self-identified social studies haters at this school more strongly engaged in the social studies content when they participated in the simulation game on the Electoral College. The research also determined UDL enhanced engagement in the simulation game. INDEX WORDS: Social students, Engagement, Simulation, Constructionism, Universal design for learning.

Logo Matching for Document Image Retrieval

Graphics detection and recognition are fundamental research problems in document image analysis and retrieval. As one of the most pervasive graphical elements in business and government documents, logos may enable immediate identification of organizational entities and serve extensively as a declaration of a document's source and ownership. In this work, we developed an automatic logo-based document image retrieval system that handles: 1) Logo detection and segmentation by boosting a cascade of classifiers across multiple image scales; and 2) Logo matching using translation, scale, and rotation invariant shape descriptors and matching algorithms. Our approach is segmentation free and layout independent and we address logo retrieval in an unconstrained setting of 2-D feature point matching. Finally, we quantitatively evaluate the effectiveness of our approach using large collections of real-world complex document images.
CONPASU-tool: A Concurrent Process Analysis Support Tool based on Symbolic Computation

This paper presents an analysis-method of concurrent proce sses with valuepassing which may cause infinite-state systems. The method c onsists of two steps: sequentialisation and state-reduction. In the sequential isation, the symbolic transition graph of a given concurrent process is derived by symbolic op erational semantics. In the state-reduction, the number of states in the symbolic tr ansition graph is reduced by removing needless internal transitions. Furthermore, thi s paper introduces an analysistool calledCONPASU, which implements the analysis-method, and demonstrates h ow CONPASU can be used for automatically analyzing concurrent process es. For example, it can extract abstract behaviors, which are useful for unde rstanding complex behaviors, by focusing on some interesting events.
Origin of the Radio Frequency Pulse Artifact in Simultaneous EEG-fMRI Recording: Rectification at the Carbon-Metal Interface

Simultaneous electroencephalograph-functional magnetic resonance imaging (EEG-fMRI ) recording has become an important tool for investigating spatiotemporal properties of brain events, such as epilepsy, evoked brain responses, and changes in brain rhythms. Reduction of noise in EEG signals during fMRI recording is crucial for acquiring high-quality EEG-fMRI data. The main source of the noise includes the gradient artifact, the radio frequency (RF) pulse artifact, and the cardiac pulse artifact. Since the RF pulse artifact is relatively small in amplitude, little attention has been paid to this artifact, and its origin is not well understood. However, the amplitude of the RF pulse artifact fluctuates randomly even if a very high EEG sampling rate is used, making it more salient than the gradient artifact after postprocessing for noise removal. In this paper, we investigate the cause of the RF pulse artifact in EEG systems that use carbon wires.
