Ballistic Transport in Metallic Nanotubes with Reliable Pd Ohmic Contacts

Contacting metallic single-walled carbon nanotubes by palladium (Pd) affords highly reproducible ohmic contacts and allows for the detailed elucidation of ballistic transport in metallic nanotubes. The Pd ohmic contacts are more reliable than the titanium (Ti) previously used for ballistic nanotube devices. In contrast, Pt contacts appear to give nonohmic contacts to metallic nanotubes. For both ohmic and nonohmic contacts, the length of the nanotube under the metal contact area is electrically turned off. Transport occurs from metal to nanotube at the edges of the contacts. Measurements with large numbers of Pd-contacted nanotube samples reveal that the mean free path for defect scattering in SWNTs grown by chemical vapor deposition can be up to 4 Im. The mean free paths for acoustic phonon scattering are on the order of 500 nm at room temperature and . 4 Im at low temperatures. Ohmic contacts with minimum contact resistance are important to the fundamental characterization and realization of high-performance devices of electronic materials. Ohmic contacts to individual metallic single-walled carbon nanotubes (m-SWNTs) by Cr and Ti have enabled the observation
All-fiber repetition-rate stabilization of mode-locked lasers for ultralow-noise microwave generation

We demonstrate a novel all-fiber repetition-rate stabilization method of mode-locked lasers. The method is based on an all-fiber Michelson interferometer with a km-scale fiber delay line. By stabilizing the laser to a 7-km-long fiber delay, the absolute integrated rms timing jitter of mode-locked Er-fiber laser is suppressed from 10 ps to 6.5 fs over 1 s. The absolute frequency instability (Allan deviation) reaches 4.3×10-14 at 0.1 s.
Approximating Carathéodory's Theorem and Nash Equilibria

In this talk I will present an approximate version of Caratheodory’s theorem and its algorithmic applications. In particular, I will show that for every vector in the convex hull of a set of vectors X there exists a nearby (under p-norm distance, for p at least 2) vector that can be expressed as a convex combination of at most b vectors of X, where the bound b is independent of the dimension of the vectors. Given the significance of Caratheodory’s theorem, this approximate version is interesting in its own right. It also has notable algorithmic applications. Specifically, I will describe how this approximate version of Caratheodory’s theorem leads to a new algorithm for computing approximate Nash equilibria in two-player games. This algorithm, in particular, provides a polynomial-time approximation scheme for Nash equilibrium in games where the sum of the payoff matrices is sparse. Moreover, for arbitrary two-player games the running time of the algorithm matches the best-known upper bound, which is obtained in (Lipton, Markakis, and Mehta 2003).

Improvement, Learning and Retention of Skill at Visual Search

Three experiments examined factors responsible for improvement in visual search. In Experiment I three groups of subjects were each trained for 3000 trials to search for a particular set of target letters among a particular set of background letters. After intervals of 2, 4, or 6 weeks without further practice they were re-tested, either with the same displays or on new displays which they searched for the same target items among new background items. Negative transfer suggested that memory for specific cue-systems distinguishing target from background letters is retained for as long as 4 weeks. Experiment II examined performance of three very highly practised subjects. After 25 days practice, variations in the size of the target set no longer affected search time. This could not be explained by learning of specific cue systems, since after this amount of practice subjects showed perfect transfer to displays which they searched for the same target items among new background items. Experiment III suggested that practised subjects achieve this high level of competence by learning to make two independent successive decisions, first to locate any member of the target set on the display and next to identify which particular member of the target set has been located.
Chemical composition, antioxidant and antimicrobial properties of Rapa Catozza Napoletana (Brassica rapa L. var. rapa DC.) seed meal, a promising protein source of Campania region (southern Italy) horticultural germplasm.

BACKGROUND The present study is the first effort in a comprehensive evaluation of the nutritive and biological properties of the meal from Rapa Catozza Napoletana (RCN) (Brassica rapa L. var. rapa) cultivar seeds as a new and alternative source of proteins. RESULTS RCN seed meal revealed a good protein content (382.0 g kg(-1)) compared with conventional Brassica defatted meals. Total glucosinolates (6.0 g kg(-1)) were comparable to or even lower than those reported for other yellow- and brown-seeded cultivars. Low levels of both sinapine and phytic acid (10.0 and 10.0 g kg(-1) respectively) suggest a minor influence of these compounds on meal mineral availability. The meal revealed quite a high polyphenolic content (13.0 g kg(-1)) composed of flavonol and hydroxycinnamic derivatives. With regard to meal biological properties, a higher radical-scavenging potential than reducing capacity and a broad antimicrobial spectrum, mainly against food-borne pathogens, were detected. CONCLUSION RCN seed meal could be highly regarded as a component of human nutrition and animal feed for its good protein content, desirable amino acid profile and low antinutrient concentration. Results for the sample indicated appreciable antiradical activity and good properties for meal stability.
Intra-bone marrow injection of mesenchymal stem cells improves the femur bone mass of osteoporotic female rats

The effect of intra-bone injection of differentiated rat bone marrow mesenchymal stem cells (BMMSCs) into the femur of osteoporotic female rats was studied. Osteoporosis was induced in Wistar female rats by bilateral ovariectomy. Then, 0.75 million BMMSCs isolated from healthy rats were injected into the femurs of osteoporotic rats. Histomorphometric analysis and histology clearly revealed improvements in the treated group as compared to untreated group. In 2 months, the femurs of treated rats, unlike untreated rats, showed trabecular bone percentage almost similar to the femurs from control healthy rats. To confirm the origin of newly formed bone, the experiment was repeated with BMMSCs isolated from green fluorescent protein transgenic rats. Confocal microscopy demonstrated green fluorescent protein-positive cells at the surface of trabecular bone of the treated rats. We investigated in vitro osteogenic differentiation of BMMSCs isolated from osteoporotic rats by studying alkaline phosphatase activity, collagen synthesis, and the ability to form mineralized nodules. Osteoporotic BMMSCs showed less differentiation capabilities as compared to those isolated from healthy rats. The results clearly demonstrated the importance of BMMSCs in osteoporosis and that the disease can be treated by injection of BMMSCs.
Powered bipeds based on passive dynamic principles

We describe three bipedal robots that are designed and controlled based on principles learned from the gaits of passive dynamic walking robots. This paper explains the common control structure and design procedure used to determine the mechanical and control parameters of each robot. We present this work in the context of three robots: Denise, the Delft pneumatic biped, R1, a highly backdrivable electric biped, and R2, a hydraulic biped. This work illustrates the application of passive dynamic principles to powered systems with significant control authority
Large Ameloblastoma of Mandible: Our Experience with Intermaxillary Fixation

Ameloblastomas are benign dental tumors, constituting 15% of oral neoplasms, most frequent odontogenic tumor of the jaw. Patient presenting at a late stage usually presents with large swelling with facial deformity. We present a case of 50 years old male who presented with recurrent ameloblastoma on the left side of the mandible causing facial disfigurement and functional impairment. Adequate removal of the tumor required hemimandibulectomy and intermaxillary fixation was done without any bony reconstruction. We would like to focus on the excellent postoperative result with regard to facial symmetry and functional improvement obtained in this case, though the available management protocols differ and are more advanced in current scenario. This case report gives hope and guidance to the surgeons who face difficulty in managing the deforming benign bony tumors due to the unavailability of facility and funds to reconstruct.
Reliability and validity of medicine ball toss tests as clinical measures of core strength

BACKGROUND: Core strengthening is a signiﬁcant component of training programs utilized to optimize athletic performance, reduce injury, and facilitate return from injury. Reliable and valid clinical measures of core strength are necessary to determine the effectiveness of these programs. OBJECTIVE: The purpose was to determine the reliability and validity of three medicine ball toss tests (MBTs). METHODS: A total of 20 healthy, physically active individuals participated. Session one included isokinetic strength testing (trunk ﬂexion/extension, and right/left rotation) and MBTs (forward, backward, and right/left rotation); session two included only the MBTs. Average peak torque during strength testing and the average distance of three MBTs in each direction were analyzed. Intraclass correlations were calculated to determine the reliability of the MBTs between sessions, while validity between MBTs and strength was assessed though Pearson correlations. RESULTS: Signiﬁcant ICCs were observed between forward, backward, and right/left rotation MBTs (ICC = 0.835; ICC = 0.835; ICC = 0.870; ICC = 0.909; p < 0.001, respectively). No signiﬁcant correlations were observed between the MBTs and corresponding measures of strength. CONCLUSION: Results illustrate that MBTs have excellent reliability but are not related to isokinetic strength as measured by average peak torque. This lack of relationship may be due to differences in muscles examined, contraction type, and/or motion performed.
Distractor Heterogeneity versus Linear Separability in Colour Visual Search

D'Zmura, and Bauer, Jolicoeur, and Cowan demonstrated that a target whose chromaticity was linearly separable from distractor chromaticities was relatively easy to detect in a search display, whereas a target that was not linearly separable from the distractor chromaticities resulted in steep search slopes. This linear separability effect suggests that efficient colour visual search is mediated by a chromatically linear mechanism. Failure of this mechanism leads to search performance strongly influenced by number of search items (set size). In their studies, linear separability was confounded with distractor heterogeneity and thus the results attributed to linear separability were also consistent with the model of visual search proposed by Duncan and Humphreys in which search performance is determined in part by distractor heterogeneity. We contrasted the predictions based on linear separability and on the Duncan and Humphreys model by varying the ratios of the quantities of the two distractors and demonstrated the potent effects of linear separability in a design that deconfounded linear separability and distractor heterogeneity.
The Multiple Self-Aspects Framework: Self-Concept Representation and Its Implications

The multiple self-aspects framework (MSF) conceives of the self-concept as a collection of multiple, context-dependent selves. From this perspective, five principles are derived, addressing issues such as how context activates particular regions of self-knowledge and how self-relevant feedback affects self-evaluations and affect. Support for these principles is discussed. Furthermore, the MSF advances several novel predictions, including how active self-aspects filter one’s experiences and perceptions, how the impact of chronic accessibility is more circumscribed than previously realized, and how self-concept representation modulates the experience of affect. In addition, the MSF helps integrate isolated lines of research within several diverse literatures, including self-regulation, stability and variability for the self, the integration of others into the self-concept, and several individual difference factors as well. Overall, the current work speaks to issues of relevance to several subdisciplines in psychology (e.g., cultural, developmental, personality, social) interested in the self, providing conceptual and methodological insights.
New H2O masers in Seyfert and FIR bright galaxies III. The southern sample

Context. A relationship between the water maser detection rate and far infrared (FIR) flux densities was established as a result of two 22 GHz maser surveys in a complete sample of galaxies (Dec > −30°) with flux densities of >50 Jy and >30 Jy. Aims. We attempted to discover new maser sources and investigate the galaxies hosting the maser spots by extending previous surveys to southern galaxies with particular emphasis on the study of their nuclear regions. Methods. A sample of 12 galaxies with Dec 50 Jy was observed with the 70-m telescope of the Canberra deep space communication complex (CDSCC) at Tidbinbilla (Australia) in a search for water maser emission. The average 3σ noise level of the survey was 15 mJy for a 0.42 km s^(−1) channel, corresponding to a detection threshold of ∼0.1 L_☉ for the isotropic maser luminosity at a distance of 25 Mpc. Results. Two new detections are reported: a kilomaser with an isotropic luminosity L_(H_(2)O) ~ 5 L_☉ in NGC 3620 and a maser with about twice this luminosity in the merger system NGC 3256. The detections have been followed-up by continuum and spectral line interferometric observations with the Australia Telescope Compact Array (ATCA). In NGC 3256, a fraction (about a third) of the maser emission originates in two hot spots associated with star formation activity, which are offset from the galactic nuclei of the system. The remaining emission may originate in weaker centres of maser activity distributed over the central 50". For NGC 3620, the water maser is coincident with the nuclear region of the galaxy. Our continuum observations indicate that the nature of the nuclear emission is probably linked to particularly intense star formation. Including the historical detection in NGC 4945, the water maser detection rate in the southern sample is 15% (3/20), consistent with the northern sample. The high rate of maser detections in the complete all-sky FIR sample (23%, 15/65) confirms the existence of a link between overall FIR flux density and maser phenomena. A relation between H_(2)O and OH masers in the FIR sample is also discussed.
LOX-1 in Ischemic Stroke

LOX-1, an OLR1 gene product, has been found to be the receptor for oxidized low density lipoprotein (LDL) to induce endothelial dysfunction. Animal studies suggested that LOX-1 promotes atherosclerosis, aggravates myocardial infarction, and enhances restenosis. Although researchers have mainly focused on coronary artery disease, reports on ischemic stroke are gradually accumulating. In parallel, more human epidemiological and clinical studies are being reported. Here we describe ligands and the receptor LOX-1 separately to clarify the current status.
Schooling and Work: Social Constraints on Equal Educational Opportunity

In order effectively to socialize children to competence in the adult roles available to them, schools must produce a highly differentiated pool of graduates to fill the requirements of hierarchically stratified work roles in the United States. In this paper we compare how two public elementary schools in an upper-middle class and a lower-middle class neighborhood socialize children along the dimensions of cognitive competence, self-image, and relationship to authority. Our findings suggest that schools differentially socialize children to respond to authority so as to be competent in adult work roles similar to those currently held by their parents.
A Joint SW/HW Approach for Reducing Register File Vulnerability

The Register File (RF) is a particularly vulnerable component within processor core and at the same time a hotspot with high power density. To reduce RF vulnerability, conventional HW-only approaches such as Error Correction Codes (ECCs) or modular redundancies are not suitable due to their significant power overhead. Conversely, SW-only approaches either have limited improvement on RF reliability or require considerable performance overhead. As a result, new approaches are needed that reduce RF vulnerability with minimal power and performance overhead. This article introduces Application-guided Reliability-enhanced Register file Architecture (ARRA), a novel approach to reduce RF vulnerability of embedded processors. Taking advantage of uneven register utilization, ARRA mirrors, guided by a SW instrumentation, frequently used active registers into passive registers. ARRA is particularly suitable for control applications, as they have a high reliability demand with fairly low (uneven) RF utilization. ARRA is a cross-layer joint HW/SW approach based on an ARRA-extended RF microarchitecture, an ISA extension, as well as static binary analysis and instrumentation. We evaluate ARRA benefits using an ARRA-enhanced Blackfin processor executing a set of DSPBench and MiBench benchmarks. We quantify the benefits using RF Vulnerability Factor (RFVF) and Mean Work To Failure (MWTF). ARRA significantly reduces RFVF from 35% to 6.9% in cost of 0.5% performance lost for control applications. With ARRA’s register mirroring, it can also correct Multiple Bit Upsets (MBUs) errors, achieving an 8x increase in MWTF. Compared to a partially ECC-protected RF approach, ARRA demonstrates higher efficiency by achieving comparable vulnerability reduction at much lower power consumption.
Oncogenic ALK regulates EMT in non-small cell lung carcinoma through repression of the epithelial splicing regulatory protein 1

A subset of Non-Small Cell Lung Carcinoma (NSCLC) carries chromosomal rearrangements involving the Anaplastic Lymphoma Kinase (ALK) gene. ALK-rearranged NSCLC are typically adenocarcinoma characterized by a solid signet-ring cell pattern that is frequently associated with a metastatic phenotype. Recent reports linked the presence of ALK rearrangement to an epithelial-mesenchymal transition (EMT) phenotype in NSCLC, but the extent and the mechanisms of an ALK-mediated EMT in ALK-rearranged NSCLC are largely unknown. We found that the ALK-rearranged H2228 and DFCI032, but not the H3122, cell lines displayed a mesenchymal phenotype. In these cell lines, oncogenic ALK activity dictated an EMT phenotype by directly suppressing E-cadherin and up-regulating vimentin expression, as well as expression of other genes involved in EMT. We found that the epithelial splicing regulatory protein 1 (ESRP1), a key regulator of the splicing switch during EMT, was repressed by EML4-ALK activity. The treatment of NSCLC cells with ALK tyrosine kinase inhibitors (TKIs) led to up-regulation of ESRP1 and E-cadherin, thus reverting the phenotype from mesenchymal to epithelial (MET). Consistently, ESRP1 knock-down impaired E-cadherin up-regulation upon ALK inhibition, whereas enforced expression of ESRP1 was sufficient to increase E-cadherin expression. These findings demonstrate an ALK oncogenic activity in the regulation of an EMT phenotype in a subset of NSCLC with potential implications for the biology of ALK-rearranged NSCLC in terms of metastatic propensity and resistance to therapy.
Teaching Geriatrics Using an Innovative, Individual‐Centered Educational Game: Students and Educators Win. A Proof‐of‐Concept Study

Given the increasingly aging population, nearly every doctor will encounter elderly adults who present with multiple complex comorbidities that can challenge even experienced physicians. This may explain why many medical students do not have a positive attitude toward elderly adults and find the complexity of their problems overwhelming. It was hypothesized that a recently developed medical school geriatrics course, based on the game GeriatriX and designed specifically to address the complexities associated with decision‐making in geriatrics, can have a positive effect on attitudes toward geriatrics and on perceived knowledge of geriatrics. The effects of this game‐based course were evaluated as a proof of concept. The assessment was based on the Aging Semantic Differential (ASD) and a validated self‐perceived knowledge scale of geriatric topics. The usability of (and satisfaction with) GeriatriX was also assessed using a 5‐point Likert scale. After completion of the course, the ASD changed significantly in the geriatrics course group (n = 29; P = .02) but not in a control group that took a neuroscience course (n = 24; P = .30). Moreover, the geriatrics course group had a significant increase in self‐perceived knowledge for 12 of the 18 topics (P = .002), whereas in the control group self‐perceived knowledge increased significantly for one topic only (sensory impairment) (P = .04). Finally, the geriatrics students reported enjoying GeriatriX. This proof‐of‐concept study clearly supports the hypothesis that a 4‐week course using a modern educational approach such as GeriatriX can improve students' self‐perceived knowledge of geriatrics and their attitudes toward elderly adults.
PROMISCUITY DRIVES SEXUAL SELECTION IN A SOCIALLY MONOGAMOUS BIRD

Abstract Many socially monogamous species paradoxically show signs of strong sexual selection, suggesting cryptic sources of sexual competition among males. Darwin argued that sexual selection could operate in monogamous systems if breeding sex ratios are biased or if some males attract highly fecund females. Alternatively, sexual selection might result from promiscuous copulations outside the pair bond, although several recent studies have cast doubt on this possibility, in particular by showing that variance in apparent male reproductive success (number of social young) differs little from variance in actual male reproductive success (number of young sired). Our results from a long-term study of the socially monogamous splendid fairy-wren (Malurus splendens) demonstrate that such comparisons are misleading and do not adequately assess the effects of extra-pair paternity (EPP). By partitioning the opportunity for selection and calculating Bateman gradients, we show that EPP has a strong effect on male annual and lifetime fitness, whereas other proposed mechanisms of sexual selection do not. Thus, EPP drives sexual selection in this, and possibly other, socially monogamous species.
Constructing the Self and Changing Others: Reconsidering `Normative Power Europe'

The European Union (EU) is widely seen as a novel kind of actor in international politics. This has been captured succinctly by Ian Manner's term `normative power Europe'. This article reviews the literature on the concept of normative power and relates it to the earlier literature on civilian power. It argues that these concepts of power should be seen as part of the same discourse; a discourse which is not confined to the EU, but includes the cases of other great powers, such as the United States (US). The example of the US leads to a problematisation of `normative power Europe' that does not focus on the discrepancy between rhetoric and concrete policies, or on the inconsistencies of EU policies, but on the political effects of the construction of the EU as a normative power; i.e., on the power of the `normative power Europe' discourse. With illustrations drawn from the Euro-Mediterranean Partnership, Turkey-EU relations and the sanctions against Austria, I argue that this discourse establishes a particular identity for the EU through turning third parties into `others' and representing the EU as a positive force in world politics. The article concludes with a call for more reflexivity in the representation of the EU as a normative power.
