Linear sparse array synthesis using Modified Bayesian Optimization Algorithm

In this paper, a new approach for sparse array synthesis is proposed. It is based on the use of a recently introduced improved version of the Bayesian Optimization Algorithm (BOA), named Modified BOA (M-BOA), that has already proved its outperforming capabilities with respect to the standard BOA as well as other well-know optimization approaches. Moreover, in opposite to what is generally done relatively to sparse arrays, here an asymmetric configuration is considered, so that the number of control parameters that could be managed by the optimizer is doubled. The results on several configurations show that the sparse arrays designed with the approach here introduced outperform those synthesized with other techniques. As a proof of concept, the results relative to a 37 element linear sparse array are here presented and discussed.
Evaluating Reranking Methods based on Link Co-occurrence and Category in Wikipedia

We often use search engines in order to find appropriate documents on the Web. However, it is often the case that we cannot find desired information easily by giving a single query. In this paper, we present a method to extract related words for the query by using the various features of Wikipedia and rank learning. We aim at developing a system to assist the user in retrieving Web pages by reranking search results.
Recognition of blurred license plate images

In video forensics, to recognize objects in low-resolution frames is a commonly seen problem. In this paper, we propose a systematic way to recognize blurred license plate images. Our method only uses one license plate image and character segmentation is not necessary. The process involves three steps. First, using single-character templates, we identify the positions of characters on a license plate and estimate the corresponding character list. Then, the position of a special symbol on the license plate is estimated. Finally, to refine the recognition results, we expand the single-character templates to multiple-character templates. The experiment results demonstrate the efficacy of our method in recognizing characters in blurred license plate images.
The Impacts of Information-Sharing Mechanisms on Spatial Market Formation Based on Agent-Based Modeling

There has been an increasing interest in the geographic aspects of economic development, exemplified by P. Krugman’s logical analysis. We show in this paper that the geographic aspects of economic development can be modeled using multi-agent systems that incorporate multiple underlying factors. The extent of information sharing is assumed to be a driving force that leads to economic geographic heterogeneity across locations without geographic advantages or disadvantages. We propose an agent-based market model that considers a spectrum of different information-sharing mechanisms: no information sharing, information sharing among friends and pheromone-like information sharing. Finally, we build a unified model that accommodates all three of these information-sharing mechanisms based on the number of friends who can share information. We find that the no information-sharing model does not yield large economic zones, and more information sharing can give rise to a power-law distribution of market size that corresponds to the stylized fact of city size and firm size distributions. The simulations show that this model is robust. This paper provides an alternative approach to studying economic geographic development, and this model could be used as a test bed to validate the detailed assumptions that regulate real economic agglomeration.
A Compact Model for Single-Poly Multitime Programmable Memory Cells

A compact model for the single-poly multitime programmable (MTP) memory cells is presented in this paper for the first time. It is based on the charge balance approach, while the traditional old model is on the fixed capacitive coupling approach. The proposed cell model has been implemented by Verilog-A and integrated into commercial SPICE simulator. The model supports both dc and transient analyses, and the simulated results are consistent very well with those from device simulation and measurement, whereas the results by the traditional old model deviate substantially. Furthermore, the comprehensive optimization of the MTP cells is made feasible thanks to the new model, such as device size, high voltage ramp rate, and reliability prediction. As a result, this compact cell model will be very useful for the designers to evaluate and optimize a single-poly MTP cell.
On the number of full levels in tries

We study the asymptotic distribution of the fill‐up level in a binary trie built over n independent strings generated by a biased memoryless source. The fill‐up level is the number of full levels in a tree. A level is full if it contains the maximum allowable number of nodes (e.g., in a binary tree level k can have up to 2k nodes). The fill‐up level finds many interesting applications, e.g., in the internet IP lookup problem and in the analysis of level compressed tries (LC tries). In this paper, we present a complete asymptotic characterization of the fill‐up distribution. In particular, we prove that this distribution concentrates on one or two points around the most probably value k = ⌊log1/qn − log log log n + 1 + log log(p/q)⌋, where p > q = 1 − p is the probability of generating the more likely symbol (while q = 1 − p is the probability of the less likely symbol). We derive our results by analytic methods such as generating functions, Mellin transform, the saddle point method, and analytic depoissonization. We also present some numerical verification of our results. © 2004 Wiley Periodicals, Inc. Random Struct. Alg. , 2004

Intercultural language learning: cultural mediation within the curriculum of Translation and Interpreting studies

This paper addresses the interrelationship of languages and cultures in the process of learning/teaching English in Translation Faculties in Spain. The fact that languages cannot be separated from their social and cultural contexts of use is widely recognised nowadays. In addition, for the last decade, intercultural language learning has been highlighted as a main objective of language acquisition, the term �intercultural� implying a back-and-forth movement across languages and cultures, a development of an understanding of one�s own language and culture in relation to a second one. Building on a comprehensive review of the literature in the field of culture in language teaching, intercultural competence, and intercultural learning and teaching, the present paper aims at providing a framework for designing a curriculum for intercultural language learning and cultural mediation in Translation Faculties in Spain
Quantitative risk assessment to enhance aeromacs security in SESAR

This paper presents the simulation results relevant to the 15.2. 7 Working Package of the European SESAR Project1. The main goal was to conduct a risk assessment of network security for the AeroMACS airport network. The risk analysis is based on a new approach for network security assessment that measures quantitatively the network risk level. Critical aspects such as the impact of a successful attack on a node and the risk propagation of that attack within an aeronautical wireless airport communication network have been taken into account. We specifically focus on the access network vulnerabilities, and a first network risk study is conducted for a predefined scenario. Some security guideline are provided to enhance the security policies and to improve the end-to-end security using some additional mechanisms such as certificate-based authentication.
Analysis of the chicken retina with an adaptive optics multiphoton microscope

The structure and organization of the chicken retina has been investigated with an adaptive optics multiphoton imaging microscope in a backward configuration. Non-stained flat-mounted retinal tissues were imaged at different depths, from the retinal nerve fiber layer to the outer segment, by detecting the intrinsic nonlinear fluorescent signal. From the stacks of images corresponding to the different retinal layers, volume renderings of the entire retina were reconstructed. The density of photoreceptors and ganglion cells layer were directly estimated from the images as a function of the retinal eccentricity. The maximum anatomical resolving power at different retinal eccentricities was also calculated. This technique could be used for a better characterization of retinal alterations during myopia development, and may be useful for visualization of retinal pathologies and intoxication during pharmacological studies.
Crystal structure of 1,7,8,9-tetrachloro-4-(2-fluorobenzyl)-10,10-dimethoxy-4-azatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione

In the title compound, C17H12Cl4FNO4, the configuration of the cycloalkene skeleton is endo,cis. The benzene ring is twisted by 71.01 (11)° from the attached pyrrolidine ring. In the crystal, one of the methine groups of the fused-ring system forms a weak C—H⋯O hydrogen bond. The other methine groups participates in a C—H⋯F interaction to the same adjacent molecule. Together, these generate [010] chains.
A Web-Based Cultural Competency Training for Medical Students: A Randomized Trial

Background:The objectives of this research were to compare a Web-based curriculum with a traditional lecture format on medical students' cultural competency attitudes using a standardized instrument and to examine the internal consistency of the standardized instrument. Methods:In 2010, we randomized all 180 1st-year medical students into a Web-based (intervention group) or a lecture-based (control group) cultural competency training. The main outcome was the overall score on the Health Belief Attitudes Survey (1 = lowest, 6 = highest). We examined internal consistency with factor analysis. Results:No differences were observed in the overall median scores between the intervention (median 5.2; 25th percentile [Q1] 4.9, 75th percentile [Q3] 5.5) and the control groups (median 5.3, Q1 4.9, Q3 5.6) (P = 0.77). The internal consistency of the 2 main subcomponents was good (Cronbach's alpha = 0.83) to acceptable (Cronbach's alpha = 0.69). Conclusions:A Web-based and a lecture-based cultural competency training strategies were associated with equally high positive attitudes among 1st-year medical students. These findings warrant further evaluation of Web-based cultural competency educational interventions.
Observer design of discrete-time T-S fuzzy systems via an efficient multi-instant fuzzy observer

The problem of reducing conservatism of observer design of discrete-time Takagi-Sugeno fuzzy systems is addressed via a new kind of fuzzy observer. The so-called multi-instant fuzzy observer is parameter-dependent on both past-time and current-time normalized fuzzy weighting functions. Since more information about the underlying fuzzy systems could be involved into observer design, the conservatism of observer design for discrete-time Takagi-Sugeno fuzzy systems can be significantly reduced. In particular, some existing fuzzy observers are special cases of the multi-instant fuzzy observer proposed in this paper. Finally, a numerical example is given to illustrate the effectiveness of the proposed results.
Building Construction Sets by Tiling Grammar Simplification

This paper poses the problem of fabricating physical construction sets from example geometry: A construction set provides a small number of different types of building blocks from which the example model as well as many similar variants can be reassembled. This process is formalized by tiling grammars. Our core contribution is an approach for simplifying tiling grammars such that we obtain physically manufacturable building blocks of controllable granularity while retaining variability, i.e., the ability to construct many different, related shapes. Simplification is performed by sequences of two types of elementary Operations: non‐local joint edge collapses in the tile graphs reduce the granularity of the decomposition and approximate replacement Operations reduce redundancy. We evaluate our method on abstract graph grammars in addition to computing several physical construction sets, which are manufactured using a commodity 3D printer.

An Efficient Corpus Based Part-of-Speech Tagging with GEP

Text corpora which are tagged with part-of-speech (pos) information are useful in many areas of linguistic research. This paper proposes a model of Genetic Expression Programming (GEP) for pos tagging. GEP is used to search for appropriate structures in function space. After the evolution of sequence of tags, GEP can find the best individual as solution. Before simulation, a set of appropriate parameters of algorithm is fitted. Experiments on Brown Corpus show that the proposed model can achieve higher accuracy rate than Genetic Algorithm model and HMM model.
Innovatief werkgedrag en stress als reacties op roloverlading en rolambiguïteit

Volgens de roltheorie (Kahn, Wolfe, Quinn, Snoek & Rosenthal, 1964) oefenen alle leden in een organisatie, van typiste tot directeur, een specifieke rol uit. Een rol is te definieren als een set van taakgebonden gedragingen die van de rolbekleder wordt verwacht teneinde de individuele taakuitvoering en taakafstemming met andere rolbekleders te reguleren (Jones, 2001). In de uitoefening van een rol kunnen rolproblemen optreden, zoals roloverlading en rolambiguiteit. Er is sprake van roloverlading wanneer een medewerker te veel taken tegelijk moet uitvoeren, of wanneer hij of zij te weinig tijd heeft om de vereiste taken adequaat uit te voeren (Kahn et al., 1964). Voorgaand onderzoek heeft aangetoond dat medewerkers innovatief werkgedrag toepassen als een strategie om roloverlading effectief te kunnen hanteren (Bunce & West, 1994; Janssen, 2000; West, 1989). Een innovatieve hantering van roloverlading kan bijvoorbeeld bestaan uit de ontwikkeling en introductie van nieuwe werkmethoden waardoor de taken sneller en adequater kunnen worden uitgevoerd, zodat de roloverlading afneemt.
A new T-type NPC-based submodule for modular multilevel cascaded converters

This paper presents a novel 4-Level T-Type Neutral-Point-Clamped (4LT2-NPC) submodule for modular multilevel cascaded converter (MMCC) family. Using the proposed modules in the cascaded converters is advantageous in reducing the number of submodules, thus reducing the dimensions of the converter. It is also shown; this new solution can contribute not only in reduction of converter submodules, but can also offer additional controllability in controlling the converter and overcome the typical NPC multilevel submodule drawback of dc capacitor voltage balancing limitation. The switching states and capacitor balancing of the new submodule are analyzed and a balancing scheme is introduced. The operation of the proposed submodule in MMCC is validated by simulation results.
CHANGES IN THE SUBMILLI-AND MILLISECOND KINETICS OF DARK RELAXATION OF DELAYED FLUORESCENCE IN TOBACCO LEAVES UNDER CONDITIONS OF BACTERIAL INFECTION BY PSEUDOMONAS SYRINGAE PV . TABACI

The influence of Pseudomonas syringae pv. tabaci from the first to tenth day after infections on three tobacco cultivars – Nevrokop 1146, transgenic Nevrokop 1146 and Aurea mutant was studied. The kinetics of dark relaxation of delayed fluorescence in the time range from 200 μs to 5.5 ms were investigated. A drop in the quantum yield of delayed fluorescence in the sensitive cultivar Nevrokop 1146 was established. An enhancement of the characteristic times with the development of the infection was observed. In both sensitive cultivars – Nevrokop 1146 and Aurea mutant – more considerable changes were established in the submilliseconds component (300–800 μs). The damages of the photosynthetic apparatus as possible results of bacterial infection were mainly in the acceptor side of photosystem 2 and were connected to the electron transfer between QA and QB. The damages in the Aurea mutant were more pronounced, while the changes in the transgenic plants from the 1st to the 10th day after infection were weaker. Therefore the infection by Pseudomonas syringae pv. tabaci did not considerably affect the primary photosynthetic reactions in photosystem 2 of the transgenic plants.
Joint torque servo of a high friction robot manipulator based on time-delay control with feed-forward friction compensation

This paper addresses a torque control method in a high friction robot manipulator. A stiction feed-forward compensator is proposed to eliminate the control problem caused by the nonlinear friction and disturbance. In order to control a robot manipulator with unknown effects, a time-delay control method is used to control the torque. One degree of freedom flexible joint robot manipulator with a joint torque sensor is used to show the performance of the proposed control method.
Treatment of intracranial aneurysms by embolization with coils: a systematic review.

BACKGROUND Embolization with coils is increasingly used for the treatment of intracranial aneurysms. To assess the percentage of complications, the percentage of aneurysm occlusion, and the short-term outcome, we performed a systematic review of studies on embolization with controlled detachable or pushable coils. SUMMARY OF REVIEW To find studies on embolization with coils, we performed a MEDLINE search from January 1990 to March 1997, checked all reference lists of the studies found, performed a Science Citation Index search on Guglielmi, and hand searched recent volumes of 25 journals. Two authors independently extracted data by means of a standardized data extraction form from 48 eligible studies totalling 1383 patients. Permanent complications of embolization with controlled detachable coils occurred in 46 of 1256 patients (3.7%; 95% CI, 2.7% to 4.9%); 400 of 744 aneurysms (54%; 95% CI, 50% to 57%) were completely occluded. By means of weighted linear regression, no relation between baseline characteristics and outcome measurements was found. The results in the prespecified subgroups of patients with a ruptured aneurysm, an unruptured aneurysm, or a basilar bifurcation aneurysm were essentially the same as the overall results. CONCLUSIONS Short-term results indicate that embolization with coils is a reasonably safe treatment for patients with an unruptured aneurysm and for patients with aneurysmal subarachnoid hemorrhage. The effectiveness in terms of complete occlusion of the aneurysm is moderate. Randomized trials are warranted to compare surgical clipping with embolization with coils.
Structure-Function Studies on Small Heat Shock Protein Oligomeric Assembly and Interaction with Unfolded Polypeptides*

The small heat shock protein (smHSP) and α-crystallin genes encode a family of 12–43-kDa proteins which assemble into large multimeric structures, function as chaperones by preventing protein aggregation, and contain a conserved region termed the α-crystallin domain. Here we report on the structural and functional characterization of Caenorhabditis elegansHSP16-2, a 16-kDa smHSP produced only under stress conditions. A combination of sedimentation velocity, size exclusion chromatography, and cross-linking analyses on wild-type HSP16-2 and five derivatives demonstrate that the N-terminal domain but not most of the the C-terminal extension which follows the α-crystallin domain is essential for the oligomerization of the smHSP into high molecular weight complexes. The N terminus of HSP16-2 is found to be buried within complexes which can accommodate at least an additional 4-kDa of heterologous sequence per subunit. Studies on the interaction of HSP16-2 with fluorescently-labeled and radiolabeled actin and tubulin reveal that this smHSP possesses a high affinity for unfolded intermediates which form early on the aggregation pathway, but has no apparent substrate specificity. Furthermore, both wild-type and C-terminally-truncated HSP16-2 can function as molecular chaperones by suppressing the thermally-induced aggregation of citrate synthase. Taken together, our data on HSP16-2 and a unique 12.6-kDa smHSP we have recently characterized demonstrate that multimerization is a prerequisite for the interaction of smHSPs with unfolded protein as well as for chaperone activity.
Biological Mutualistic Models Applied to Study Open Source Software Development

The evolution of the Web has allowed the generation of several platforms for collaborative work. One of the main contributors to these advances is the Open Source initiative, in which projects are boosted to a new level of interaction and cooperation that improves their software quality and reliability. In order to understand how the group of contributors interacts with the software under development, we propose a novel methodology that adapts Lotka-Volterra-based biological models used for host-parasite interaction. In that sense, we used the concept mutualism from social parasites. Preliminary results based on experiments on the Github collaborative platform showed that Open Source phenomena can be modeled as a mutualistic system, in terms of the evolution of the population of developers and repositories.
