SUPER MAGIC AND ANTIMAGIC LABELINGS OF DISJOINT UNION OF PLANE GRAPHS Ali Ahmad, Martin Bača, Marcela Lascsáková, Andrea Semaničová-Feňovčíková 2,3 College of computer and information system, Jazan University, Jazan, Saudi Arabia Department of Appl. Mathematics and Informatics, Technical University, Košice, Slovak Republic Abdus Salam School of Mathematical Sciences, G. C. University, Lahore, Pakistan ahmadsms@gmail.com, martin.baca@tuke.sk, marcela.lascsakova@tuke.sk, andrea.fenovcikova@tuke.sk ABSTRACT: Suppose G is a finite plane graph with vertex set V(G) and edge set E(G). A d-antimagic labeling of type (1,1,0) of G is a one-to-one map from V(G)E(G) onto the integers 1,2,. ,|V(G)|+|E(G)| with the property that the labels of the vertices and edges surrounding the face add up to a weight of that face and the weights of all s-sided faces form an arithmetic progression of difference d. A d-antimagic labeling is called super if the smallest possible labels appear on the vertices. In this paper, we investigate the existence of super d-antimagic labelings of type (1,1,0) for disjoint union of plane graphs for several values of difference d. The work was supported by Higher Education Commission Pakistan Grant HEC(FD)/2007/555 and by Slovak VEGA Grant 1/0130/12.
Comparing intermittency and network measurements of words and their dependence on authorship

Many features of texts and languages can now be inferred from statistical analyses using concepts from complex networks and dynamical systems. In this paper, we quantify how topological properties of word co-occurrence networks and intermittency (or burstiness) in word distribution depend on the style of authors. Our database contains 40 books by eight authors who lived in the nineteenth and twentieth centuries, for which the following network measurements were obtained: the clustering coefficient, average shortest path lengths and betweenness. We found that the two factors with stronger dependence on authors were skewness in the distribution of word intermittency and the average shortest paths. Other factors such as betweenness and Zipf's law exponent show only weak dependence on authorship. Also assessed was the contribution from each measurement to authorship recognition using three machine learning methods. The best performance was about 65% accuracy upon combining complex networks and intermittency features with the nearest-neighbor algorithm of automatic authorship. From a detailed analysis of the interdependence of the various metrics, it is concluded that the methods used here are complementary for providing short- and long-scale perspectives on texts, which are useful for applications such as the identification of topical words and information retrieval.
The biomechanics effects of back and front pack load carriage for human locomotion

This paper described an investigation into the biomechanical effects of back and front load carriage on human locomotion performance. Ten young male subjects walked on a level under five conditions (10kg front pack, 20kg front pack, without load, 10kg backpack and 20kg backpack). For each subject, the self-selected speed was maintained at all conditions to minimize the effect of speed on gait dynamics. The kinematic and kinetic effects results during front pack or back pack load carriage were obtained with walking experiments. Analysing kinematics and kinetic during different carriage broadens the knowledge regarding the development of exercise-related injuries, while helping to inform the human-centred design process for future load carrying systems.
The explanation of effective factors on the healthy lifestyle of the nursing students' view: A qualitative study

Nurses have a key role in improving the client's health and their lifestyle is effective in representing services to the patients and client. This study aims to investigate the nursing students' perception about the effective factors on their healthy lifestyle. This study was done qualitatively with the content analysis approach and through 20 semi-structured and deep interviews with undergraduate nursing students of Tehran city. The participants were selected through purposive sampling. Data were analyzed using qualitative content analysis. All interviews were recorded, transcribed, and reviewed. Also, codes were extracted. Based on centrality, codes were put in a sub-category and then by reviewing sub-categories again, they were put in categories and finally, a theme was determined. During the process of content analysis, theme on the effective factors on nursing students' healthy life style was revealed. The theme included 9 categories: ``the perception of effective factors on health promotion'', ``having enough time'', ``inner factors'', ``work-related factors or activity'', ``environmental factors'', ``knowledge and awareness'', ``individual factors'', ``social factors'', and ``perceived priorities''. The participants believed that various and widespread factors affected their health promotion level. The extension of these factors demands the complete attention to different health dimensions and how to improve it by person, family, and community.

Resistance of Southern African varieties of sugarcane to Chilo sacchariphagus (Lepidoptera: Crambidae) in Mozambique, and development of a non-destructive field resistance rating system.

While completing preand post-release surveys of sugarcane fields for release of the pupal parasitoid Xanthopimpla stemmator against Chilo sacchariphagus in Mozambique, it was noticed that there were differences in infestation levels in similarly aged varieties of sugarcane at Acucareira de Mozambique and Companhia de Sena sugar estates. Both these estates had recently imported numerous South African varieties of sugarcane. It was also noticed that the intensity of infestation of some of these varieties by C. sacchariphagus was different to the intensity of infestation of the same varieties by Eldana saccharina under South African conditions. These differences are discussed. In addition, a difference between varieties was also noted in the degree of damage to the top leaves of different varieties of young sugarcane by early instar C. sacchariphagus. This led to the development of a promising non-destructive method of evaluating the resistance of these varieties against this borer. Comparison of the non-destructive method with the destructive stalk dissection methods showed some correlation. The method and correlations are described.
Title Symbol timing recovery for generalized minimum shift keyingmodulations in software radio receiver

A new symbol timing estimator for generalized MSK signals is proposed. It is based on the squaring algorithm and has a feedforward structure. The proposed timing estimator is fully-digital and is suitable for implementation in software radios. The performance in AWGN channel is compared with the Modified Cramer-Rao bound and that of the ML algorithm. The proposed timing estimator is found to have a performance close to that of the ML algorithm, but with a lower implementation complexity.
Proton Adsorption Selectivity of Zeolites in Aqueous Media: Effect of Si/Al Ratio of Zeolites

In addition to their well-known uses as catalysts, zeolites are utilized to adsorb and remove various cations from aqueous system. The adsorption of the cations is ascribed to the negative charge of zeolites derived from isomorphous substitution of Si by Al. The amount of Na+ adsorption on 4A, X, Y, Na-P1 and mordenite type zeolites were determined in aqueous media, in a two-cation (Na+ and H+) system. Although each zeolite has a constant amount of negative charge, the amount of Na+ adsorption of each zeolite decreased drastically at low pH−pNa values, where pH−pNa is equal to log{(Na+)/(H+)}. By using the plot of the amount of Na+ adsorption versus pH−pNa, an index of the H+ selectivity, which is similar to the pKa of acids, of each zeolite was estimated, and the index tended to increase with decreasing Si/Al ratio of zeolites. These indicate that zeolites with lower Si/Al and higher negative charge density have higher H+ adsorption selectivity, and in fact, such a zeolite species (4A and X) adsorbed considerable amount of H+ even at weakly alkaline pH region. The adsorption of H+ results in the decrease of cation adsorption ability, and may lead to the dissolution of zeolites in aqueous media.
On the Number of Times an Integer Occurs as a Binomial Coefficient

Let N(t) denote the number of times the integer t > 1 occurs as a binomial coefficient ; that is, N(t) is the number of solutions of t = (n in integers n and r. r We have N(2) = 1, N(3) = N(4) = N(5) = 2, N(6) = 3, etc. In a recent note in the research problems section of the MONTHLY, D. Singmaster [1] proved that N(t) = O(log t). He conjectured that N(t) = 0(1) but pointed out that this conjecture, if it is in fact true, is perhaps very deep. In [1] and [5], Singmaster points out that N(t) = 6 for the following values of t <_ been shown by Singmaster [5] and D. Lind [6] that N(t) >_ 6 inflaitely often. Sing-master has verified that the only value of t <_ 2 48 for which N(t) >_ 8 is t = 3003, for which N(t) = 8. In this note we obtain some additional information about the behavior of N(t). In Theorem 1 we prove that the average and normal order of N(t) is 2 ; in fact, we prove somewhat more than this, namely, the number of integers t, 1 < t 5 x, for which N(t) > 2 is 0(\/x). (See [4] p. 263 and p. 356, for the definitions of average and normal order .) In Theorem 2 we give an upper bound for N(t) in terms of the number of distinct prime factors of t. Our main result is Theorem 3, in which we show that (1) can be improved to N(t) = O(log t/log log t). Finally, in Theorem 4, we consider the related problem of determining the number of representations of an integer as a product of consecutive integers. THEOREM 1. The average and normal order of N(t) = 2 .
Pediatric Cortical Dysplasia: Correlations between Neuroimaging, Electrophysiology and Location of Cytomegalic Neurons and Balloon Cells and Glutamate/GABA Synaptic Circuits

Seizures in cortical dysplasia (CD) could be from cytomegalic neurons and balloon cells acting as epileptic ‘pacemakers’, or abnormal neurotransmission. This study examined these hypotheses using in vitro electrophysiological techniques to determine intrinsic membrane properties and spontaneous glutamatergic and GABAergic synaptic activity for normal-pyramidal neurons, cytomegalic neurons and balloon cells from 67 neocortical sites originating from 43 CD patients (ages 0.2–14 years). Magnetic resonance imaging (MRI), 18fluoro-2-deoxyglucose positron emission tomography (FDG-PET) and electrocorticography graded cortical sample sites from least to worst CD abnormality. Results found that cytomegalic neurons and balloon cells were observed more frequently in areas of severe CD compared with mild or normal CD regions as assessed by FDG-PET/MRI. Cytomegalic neurons (but not balloon cells) correlated with the worst electrocorticography scores. Electrophysiological recordings demonstrated that cytomegalic and normal-pyramidal neurons displayed similar firing properties without intrinsic bursting. By contrast, balloon cells were electrically silent. Normal-pyramidal and cytomegalic neurons displayed decreased spontaneous glutamatergic synaptic activity in areas of severe FDG-PET/MRI abnormalities compared with normal regions, while GABAergic activity was unaltered. In CD, these findings indicate that cytomegalic neurons (but not balloon cells) might contribute to epileptogenesis, but are not likely to be ‘pacemaker’ cells capable of spontaneous paroxysmal depolarizations. Furthermore, there was more GABA relative to glutamate synaptic neurotransmission in areas of severe CD. Thus, in CD tissue alternate mechanisms of epileptogenesis should be considered, and we suggest that GABAergic synaptic circuits interacting with cytomegalic and normal-pyramidal neurons with immature receptor properties might contribute to seizure generation.
Design of Pulse Waveform for Waveform Division Multiple Access UWB Wireless Communication System

A new multiple access scheme, Waveform Division Multiple Access (WDMA) based on the orthogonal wavelet function, is presented. After studying the correlation properties of different categories of single wavelet functions, the one with the best correlation property will be chosen as the foundation for combined waveform. In the communication system, each user is assigned to different combined orthogonal waveform. Demonstrated by simulation, combined waveform is more suitable than single wavelet function to be a communication medium in WDMA system. Due to the excellent orthogonality, the bit error rate (BER) of multiuser with combined waveforms is so close to that of single user in a synchronous system. That is to say, the multiple access interference (MAI) is almost eliminated. Furthermore, even in an asynchronous system without multiuser detection after matched filters, the result is still pretty ideal and satisfactory by using the third combination mode that will be mentioned in the study.
Systemic Arterial Response to Exercise in Patients With Aortic Valve Stenosis

Background— Systemic arterial hemodynamics play an important role in the assessment of the severity and hemodynamic consequences of aortic valve stenosis (AVS). Methods and Results— Systemic vascular resistance, total arterial compliance, effective arterial elastance, and aortic characteristic impedance were derived from high-fidelity catheter recordings of ascending aortic pressure and blood flow velocity at rest and with supine bicycle exercise in 18 patients with AVS and 11 control subjects. Mean aortic pressure was similar between groups. At rest, systemic vascular resistance (AVS patients, 1426±318 dynes · s · cm−5; control subjects, 107±228 dynes · s · cm−5; P<0.01), arterial elastance (AVS patients, 1.38±0.36 mm Hg/mL; control subject, 0.99±0.15 mm Hg/mL; P<0.002), and aortic characteristic impedance (AVS patients, 107±23 dynes · s · cm−5; control subjects, 76±30 dynes · s · cm−5; P<0.01) were increased, whereas total arterial compliance was lower (AVS patients, 0.737±0.19×10−3 cm5/dyne; control subjects, 1.155±0.27×10−3 cm5/dyne; P<0.001) in AVS. With exercise, total arterial compliance increased in control subjects (rest, 1.155±0.27×10−3 cm5/dyne; exercise, 1.421±0.49×10−3 cm5/dyne; P<0.05) but did not change in AVS patients (rest, 0.737±0.19×10−3 cm5/dyne; exercise, 0.769±0.21×10−3 cm5/dyne; P=0.2). Arterial elastance increased on exercise in AVS patients (rest, 1.38±0.36 mm Hg/mL; exercise, 1.57±0.44; P<0.01). Aortic characteristic impedance remained elevated on exercise (AVS patients, 122±30 dynes · s · cm−5; control subjects, 80±43 dynes · s · cm−5; P=0.01). Stroke flow increased significantly in both AVS patients (rest, 229±69 mL/s; exercise, 256±78 mL/s; P<0.01) and control subjects (rest, 230±37 mL/s; exercise, 406±69 mL/s; P<0.001), although the increment was much attenuated in AVS. On multiple regression, the increase in stroke flow was related to the decrease in systemic vascular resistance (P=0.03), increase in total arterial compliance (P=0.03), and decrease in arterial elastance (P=0.02). Conclusions— These results indicate a pressure-independent increase in the steady and pulsatile components of the arterial load in patients with AVS under resting conditions. Persistent “stiffening” of the arterial system is an important contributor to the diminished stroke output response to exercise in AVS.
The McGill University Health Centre Cancer Pain Clinic: A Retrospective Analysis of an Interdisciplinary Approach to Cancer Pain Management

Context. The McGill University Health Center (MUHC) Cancer Pain Clinic offers an interdisciplinary approach to cancer pain management for patients. The core team includes a nurse clinician specialist in oncology and palliative care, a palliativist, an anaesthetist, and a radiation oncologist. This tailored approach includes pharmacological and nonpharmacological therapies offered concurrently in an interdisciplinary fashion. Objectives. Description of the interdisciplinary MUHC cancer pain approach and analysis of treatments and outcomes. Methods. A retrospective analysis of new outpatients completing two subsequent visits (baseline and follow-ups: FU1, FU2) was conducted. Variables included (a) symptom severity measured by the Edmonton Symptom Assessment Scale, (b) pain and disability measured with the Brief Pain Inventory, and (c) analgesic plan implementation including pharmacological and nonpharmacological therapies. Results. 71 charts were reviewed. Significant pain relief was achieved consistently at FU1 and FU2. The average pain severity decreased by 2 points between initial assessment and FU2. More than half (53%) of patients responded with a pain reduction greater than 30%. Severity of other symptoms (i.e., fatigue, nausea, depression, and anxiety) and disability also decreased significantly at FU2. The total consumption of opioids remained stable; however, the consumption of short acting preparations decreased by 52% whereas the prescription of nonopioid agents increased. Beyond drug management, 60% of patients received other analgesic therapies, being the most common interventional pain procedures and psychosocial approaches. Conclusion. The MUHC interdisciplinary approach to cancer pain management provides meaningful relief of pain and other cancer-related symptoms and decreases patients' disability.
Chemically induced skin carcinogenesis: Updates in experimental models (Review)

Skin cancer is one of the most common malignancies affecting humans worldwide, and its incidence is rapidly increasing. The study of skin carcinogenesis is of major interest for both scientific research and clinical practice and the use of in vivo systems may facilitate the investigation of early alterations in the skin and of the mechanisms involved, and may also lead to the development of novel therapeutic strategies for skin cancer. This review outlines several aspects regarding the skin toxicity testing domain in mouse models of chemically induced skin carcinogenesis. There are important strain differences in view of the histological type, development and clinical evolution of the skin tumor, differences reported decades ago and confirmed by our hands-on experience. Using mouse models in preclinical testing is important due to the fact that, at the molecular level, common mechanisms with human cutaneous tumorigenesis are depicted. These animal models resemble human skin cancer development, in that genetic changes caused by carcinogens and pro-inflammatory cytokines, and simultaneous inflammation sustained by pro-inflammatory cytokines and chemokines favor tumor progression. Drugs and environmental conditions can be tested using these animal models. keeping in mind the differences between human and rodent skin physiology.
The Canada-France Redshift Survey. I. Introduction to the Survey, Photometric Catalogs, and Surface Brightness Selection Effects

The Canada-France Redshift Survey has been undertaken to provide a large well-defined sample of faint galaxies at high redshift in which the selection criteria match as closely as possible those of samples of nearby galaxies. The survey is designed to have a median redshift of z ~ 0.6 corresponding to a look-back time of half the present age of the Universe for Omega ~ 1. Such a survey can then be used for studying many different aspects of the evolution of galaxies over the interval 0 < z < 1. In this paper we describe the selection of the fields, the multicolor imaging observations and the construction and validation of the photometric catalogs. Particular attention is paid to quantifying the unavoidable selection effects in surface brightness and their impact on the survey is assessed in the context of the properties of known populations of galaxies. The photometric catalogs contain several thousand objects brighter than I_{AB}< 22.5 and are essentially complete for central surface brightnesses as faint as $\mu_{AB}(I)$ $\sim$ 24.5 mag arcsec$^{-2}$. This should be sufficient to include both normal surface brightness galaxies and prototypes of extreme low surface brightness galaxies.
On motifs and functional modules in complex networks

Although the emergence of motifs certainly reflects functional constraints and design principles underlying complex networks, our studies on digital circuits and a transcriptional regulatory network indicate that motifs are not “basic” functional building blocks as many claimed before, since most motif instances do not represent independent units that are functionally separable from the rest of the network. We also argue that the over-representation of motifs arises not because motifs are fundamental network fragments, but as a result of (1) predesigned basic functional modules consisting of motif-clusters, and (2) cross-module connections involving buses in the circuits and global regulators in the transcriptional regulatory network.
Dealing With Constraints in Sensor-Based Robot Control

A framework is presented in this paper for the control of a multisensor robot under several constraints. In this approach, the features coming from several sensors are treated as a single feature vector. The core of our approach is a weighting matrix that balances the contribution of each feature, allowing the taking of constraints into account. The constraints are considered as additional features that are smoothly injected in the control law. Multisensor modeling is introduced for the design of the control law, drawing similarities with linear quadratic control. The main properties are exposed and we propose several strategies to cope with the main drawbacks. The framework is validated in a complex experiment, illustrating various aspects of the approach. The goal is the positioning of a six-DOF robot arm with 3-D visual servoing. The considered constraints are both eye-in-hand and eye-to-hand visibility, together with joint limit avoidance. The system is thus highly overdetermined, yet the task can be performed while ensuring several combinations of constraints.
Selective Relaying in Cooperative OFDM Systems: Two-Hop Random Network

In this paper, we investigate two selective relaying schemes in cooperative OFDM systems. Selective OFDMA relaying, where the relay selection is performed in a per-subcarrier manner, and selective OFDM relaying, where one best relay among the L potential relays is selected to relay the entire OFDM block, are compared in a two-hop random network. The outage performance of equal bit allocation (EBA), where each subchannel has the same number of bits, and bit loading (BL), where bits are adaptively allocated to each subchannel, are analyzed and compared for these two approaches. The outage analysis clearly shows that a significant performance gain can be achieved by selective OFDMA relaying, whether EBA or BL is employed, compared with selective OFDM relaying. The performance gain remains the same for different relay locations. With EBA, the performance gain increases with an increase in L and N, the number of independent subchannels. For BL, the performance gain also increases with an increase in R, the average number of bits per subchannel, in addition to L and N. Centralized and decentralized implementation issues are also considered. For EBA, selective OFDMA relaying scheme is preferred because of its superior performance and simple decentralized implementation. For BL, selective OFDMA relaying scheme is a good choice for centralized systems and selective OFDM relaying is more suitable for decentralized systems at the expense of a loss in performance.
