Asymptotic Enumeration of Sparse Uniform Linear Hypergraphs with Given Degrees

A hypergraph is simple if it has no loops and no repeated edges, and a hypergraph is linear if it is simple and each pair of edges intersects in at most one vertex. For $n\geq 3$, let $r= r(n)\geq 3$ be an integer and let $\boldsymbol{k} = (k_1,\ldots, k_n)$ be a vector of nonnegative integers, where each $k_j = k_j(n)$ may depend on $n$. Let $M = M(n) = \sum_{j=1}^n k_j$ for all $n\geq 3$, and define the set $\mathcal{I} = \{ n\geq 3 \mid r(n) \text{ divides } M(n)\}$. We assume that $\mathcal{I}$ is infinite, and perform asymptotics as $n$ tends to infinity along $\mathcal{I}$. Our main result is an asymptotic enumeration formula for linear $r$-uniform hypergraphs with degree sequence $\boldsymbol{k}$. This formula holds whenever the maximum degree $k_{\max}$ satisfies $r^4 k_{\max}^4(k_{\max} + r) = o(M)$. Our approach is to work with the incidence matrix of a hypergraph, interpreted as the biadjacency matrix of a bipartite graph, enabling us to apply known enumeration results for bipartite graphs. This approach also leads to a new asymptotic enumeration formula for simple uniform hypergraphs with specified degrees, and a result regarding the girth of random bipartite graphs with specified degrees.
A Theory of Refractive Photo-Light-Path Triangulation

3D reconstruction of transparent refractive objects like a plastic bottle is challenging: they lack appearance related visual cues and merely reflect and refract light from the surrounding environment. Amongst several approaches to reconstruct such objects, the seminal work of Light-Path triangulation is highly popular because of its general applicability and analysis of minimal scenarios. A light-path is defined as the piece-wise linear path taken by a ray of light as it passes from source, through the object and into the camera. Transparent refractive objects not only affect the geometric configuration of light-paths but also their radiometric properties. In this paper, we describe a method that combines both geometric and radiometric information to do reconstruction. We show two major consequences of the addition of radiometric cues to the light-path setup. Firstly, we extend the case of scenarios in which reconstruction is plausible while reducing the minimal requirements for a unique reconstruction. This happens as a consequence of the fact that radiometric cues add an additional known variable to the already existing system of equations. Secondly, we present a simple algorithm for reconstruction, owing to the nature of the radiometric cue. We present several synthetic experiments to validate our theories, and show high quality reconstructions in challenging scenarios.
TAC-03 - A Supply-Chain Trading Competition

The Trading Agent Competition (TAC) has now become an annual fixture since its inception in 2000. The competition was conceived with the objective of studying automated trading strategies by focusing the research community on the development of competing solutions to a common trading scenario. The success of past TAC events has motivated broadening the scope of the competition beyond the context of the travel agent scenario used thus far. For the fourth edition of this competition, TAC-03, to be held in August 2003, the authors have created a novel supply-chain trading game with the aim of investigating automated agents in the context of dynamic supply-chain management.
PREPROCESSING OF EXPERIMENTAL DATA FOR USE IN MODEL BUILDING AND MODEL VALIDATION

A method for outlier detection based on the residual of system identification is presented in [1]. An alternative approach to this method is derived in this paper; outliers may cause large innovation processes (absolute values). Hence, such outliers may be detected by searching for samples having large innovation processes. In [2] it is proved that the innovation process can be identified directly from system input and system output data, without relying on models. This method is therefore well suited for outlier detection. In [3] it is shown that the innovation process identified by the method of [2] is identical to the residual of an ARX identification. Hence, the method to be derived in this paper can mathematically be proved to be a special case of the method presented in [1]: If an ARX algorithm is chosen for the system identification step in the method of [1], then the method of [1] and the method to be presented in this paper become mathematically identical. The latter method is tested on experimental data from the copper refining process of Xstrata Nikkelverk, Kristiansand, Norway. The MATLAB command delayest is used to estimate time delays between system inputs and system outputs in a dataset. A simulation study of delayest shows that the command is sensitive to: (i) The specified model order. (ii) Stochastic elements in the dataset. (iii) Whether all time delays are estimated during one execution of delayest, or whether only one time delay is estimated for each execution. delayest is also tested on experimental data from Xstrata Nikkelverk. These tests confirm that delayest is sensitive to the factors listed above.
CMOS bridging fault modeling

This paper analyses the general problem of the determination of the intermediate potentials created by a bridging fault. The analyses is made taking into account the bridge resistance value. It is shown that the fault is detectable as a logic error for a given range of bridge resistance values. But, in this range, the logic faulty value is independent of the bridge resistance value. A general electrical model which can be used to determine if a particular structure of transistors gives an intermediate voltage which is higher or lower than a given threshold voltage is proposed. A global procedure to simulate bridging fault is given. By using the proposed equations and model no SPICE simulation is required. <<ETX>>
Addiction as Mind—Body Bridge Commentary on Paper by Lisa Director

Director's paper calls our attention to the lack of attention to addiction in the relational literature. Clinical case studies of patients with chemical dependency may provide a window into the complexities of the mind—body connection in psychoanalysis. The transference—countertransference dimensions of the treatment of addicted individuals offer the therapist a privileged glimpse of the patient's internal object relations and thereby enable the therapist to gain greater understanding of the patient's characteristic problems in relationships with others.
HOW KNOWLEDGE INFLUENCED TWO INTERVENTIONS DESIGNED TO IMPROVE COMPREHENSION

Abstract The purpose of the present study was to compare two interventions designed to improve students’ comprehension of a problematic text. The first involved revising the text to improve coherence, and the second was designed to promote active engagement through asking inference‐promoting questions. Three groups of 18 fifth graders read either an original social studies text, a revised version of the text, or were asked questions while reading the original text. While the quantitative results showed no differences among the three groups in amount of information recalled and the number of questions answered correctly, qualitative analyses showed that those students who were asked questions tended to recall the central points in the passage. The lack of advantage for the revised text is in contrast to findings from previous research on promoting text comprehension through text revision. Explanations for this difference are offered by considering the unexpected effects of students’ knowledge. Further, the.
Stem Cell Review Series: Aging of the skeletal muscle stem cell niche

Declining stem cell function during aging contributes to impaired tissue function. Muscle‐specific stem cells (‘satellite cells’) are responsible for generating new muscle in response to injury in the adult. However, aged muscle displays a significant reduction in regenerative abilities and an increased susceptibility to age‐related pathologies. This review describes components of the satellite cell niche and addresses how age‐related changes in these components impinge on satellite cell function. In particular, we review changes in the key niche elements, the myofiber and the basal lamina that are in intimate contact with satellite cells. We address how these elements are influenced by factors secreted by interstitial cells, cells of the immune system, and cells associated with the vasculature, all of which change with age. In addition, we consider more distant sources of influence on the satellite cell niche that change with age, such as neural‐mediated trophic factors and electrical activity and systemic factors present in the circulation. A better understanding of the niche elements and their influence on the satellite cell will facilitate the development of therapeutic interventions aimed at improving satellite cell activity and ultimately tissue response to injury in aged individuals.
European female expatriate careers: critical success factors

The particular focus of this paper is female expatriates in Europe, which is a relatively under‐researched area. A total of 50 senior female expatriate managers were interviewed, representing a wide range of industry and service sectors. The aims of the paper are to highlight a number of critical factors which are necessary for successful female expatriate assignments. The results of the study show that female expatriates are disadvantaged in their careers because of the lack of organizational support which is readily available to their male counterparts. This lack of organizational support, together with the invisible barriers which constitute the glass ceiling, explain the relative scarcity of female expatriate managers.
Assemblage, adaptation and apps: Smartphones and mobile gaming

As scholars such as Goggin (2009a) have noted, the rapid uptake of ‘smartphones’ has reshaped the ways in which software developers, users, and academics consider the interrelationship between mobility, culture, technology hardware, and the Internet. In addition, this uptake has added a significant new layer of encrustations around what we might define as ‘standard’ uses of mobile technologies. Once limited to the playing of pre-loaded (offline) games on mobile handsets, smartphones have allowed for not only mobile interactivity and enhanced visuals, but also the possibility of downloading apps that allow the user to add multiple new dimensions to the gaming experience. These developments are but one more factor in ‘thinking about games as assemblage, wherein many varying actors and unfolding processes make up the site and action’ (Taylor 2009, 332). Taking the theoretical perspectives of adaptation (Goggin 2009a; Farnsworth and Austrin 2010) and assemblage (Taylor 2009; Goggin 2009b) we will discuss three apps linked to the enormously popular World of Warcraft game, and the ways in which these applications both reshape how we might think about and use technology, and how smartphones and mobile applications also reconfigure social, technological, and generic relations.
Re: High-dose compared with intermediate-dose methotrexate in children with a first relapse of acute lymphatic leukemia.

doses of folinic acid used (30 mg/m 2 after 1 g/m 2 intravenous MTX plus intrathecal MTX and 45 mg/m 2 intravenous MTX after 5 g/m 2 intravenous MTX plus intrathecal MTX) have caused significant neurotoxicity. More than 8% of patients had neurotoxicity when 25 mg/m 2 of folinic acid was given after 1 g/m 2 MTX. 3 A dose of 45 mg/m 2 was adequate to prevent neurotoxicity after 1 g/m 2 intravenous MTX together with intrathecal MTX. 4 L-folinic acid (37.5 mg/m 2 , equivalent to approximately 75 mg/m 2 folinic acid) resulted in neurotoxicity in 5.8% of children after 5 g/m 2 MTX. 5 A promise of improved prognosis by reducing the folinic acid dose was suggested by Borsi et al, 6 who showed a trend (but no statistical significance) toward better prognosis when less than 315 mg/m 2 folinic acid was given after 6 to 8 g/m 2 MTX: hardly justification for reducing the folinic acid dose to 15% of this critical value. Folic acid doses have been reduced again and again by the Berlin-Frankfurt-Munster (BFM) group in successive studies until the doses used here have been reached, by simply ignoring neurotoxicity. Neurotoxicity has been avoided with adequate folinic acid even with doses as high as 33.6 g/m 2 MTX. 7 Recently others have based claims that increasing the dose of folinic acid lowers cure rate on a rather flimsy base. The MTX and folinic acid doses were examined in 4 risk groups. The folinic acid levels were higher in relapsing patients in 2 groups and lower in the other 2: hardly convincing evidence! 8 Not all groups feel high- or intermediate-dose MTX is needed to treat ALL, and recently gene expression profiling seems to explain the lack of a consistent response to MTX. 9 However when MTX is used, the conclusion from this study should be that MTX doses be increased in future studies rather than reduced to 1 g/m 2 . “Minimal” dose folinic acid failed to improve prognosis and so this approach should be abandoned and appropriate doses that do not cause neurotoxicity should be adopted, such as 180 mg/m 2 folinic acid after 8 g/m 2 MTX. 10 I would suggest that a randomized study be performed comparing the toxicity and efficacy of “minimal” and “appropriate” doses of folinic acid after high-dose MTX to end this very deep controversy.
PVdF array characterisation for high frequency ultrasonic imaging

Polyvinylidenefluoride (PVdF) has been utilized for a number of years within ultrasonic hydrophones. However, polymeric materials have rarely been incorporated into medical imaging phased arrays due to lower emitted power levels (relative to PZT transducers), and higher transducer element impedance. PVdF's advantages as a transducer material lie in its inherent wide bandwidth and the potential to create high-resolution images whilst maintaining low transducer manufacturing costs. Here we report the fabrication and test of PVdF linear arrays with 28 /spl mu/m PVdF film with elements on a 250 /spl mu/m pitch. These arrays are connected to equipment that has been developed to perform transmit beamforming to a variable focal point, and receive echoes from single transducer elements that are close-coupled to a 48-channel array of amplifiers. A-line data can then be post processed to perform dynamic receive beamforming. Utilizing this equipment, measurements of pressure field distributions are presented, and compared with simulations, to determine the optimum number of pulsed elements. Using the arrays in pulse-echo mode, imaging quality is assessed with biological tissue samples and ultrasound phantoms. A prototype transducer, operated to produce ultrasound with >20MHz centre frequency, realized spatial resolution of <0.4mm laterally and 0.1mm axially, at a distance of 15mm from the transducer.
Antiatherosclerotic and Cardioprotective Potential of Acacia senegal Seeds in Diet-Induced Atherosclerosis in Rabbits

Acacia senegal L. (Fabaceae) seeds are essential ingredient of “Pachkutta,” a specific Rajasthani traditional food. The present study explored antiatherosclerotic and cardioprotective potential of Acacia senegal seed extract, if any, in hypercholesterolemic diet-induced atherosclerosis in rabbits. Atherosclerosis in rabbits was induced by feeding normal diet supplemented with oral administration of cholesterol (500 mg/kg body weight/day mixed with coconut oil) for 15 days. Circulating total cholesterol (TC), HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C), triglycerides, and VLDL-cholesterol (VLDL-C) levels; atherogenic index (AI); cardiac lipid peroxidation (LPO); planimetric studies of aortal wall; and histopathological studies of heart, aorta, kidney, and liver were performed. Apart from reduced atherosclerotic plaques in aorta (6.34 ± 0.72) and increased lumen volume (51.65 ± 3.66), administration with ethanolic extract of Acacia senegal seeds (500 mg/kg/day, p.o.) for 45 days to atherosclerotic rabbits significantly lowered serum TC, LDL-C, triglyceride, and VLDL-C levels and atherogenic index as compared to control. Atherogenic diet-induced cardiac LPO and histopathological abnormalities in aorta wall, heart, kidney, and liver were reverted to normalcy by Acacia senegal seed extract administration. The findings of the present study reveal that Acacia senegal seed extract ameliorated diet-induced atherosclerosis and could be considered as lead in the development of novel therapeutics.
Reaching for the Brass Ring of Psychometric Test Standards: Commenting on Slaney, Storey, and Barnes

Slaney, Storey, and Barnes (2011), in delineating guidelines for data-driven psychometric test evaluation, advocate modern test theory for extending a prescriptive framework proposed in Slaney and Maraun (2008). Here, with an emphasis on noncognitive tests, we begin with a historical review of psychological testing and the developments of testing theory up to current standards and practices. We argue that although the efforts of Slaney et al. are commendable and may be superior in a field in which classical test theory still dominates, they may fall upon deaf ears for two reasons. First, present psychology training is negligent in keeping up with recent developments in statistics and measurement. Second, the practical advantages of modern test theory over classical approaches have not yet been sufficiently demonstrated to test users. This is not to say modern theory cannot produce better tests, rather, when we consider that the ultimate criterion has been and will be predictive validity, old, unsophisticated, classically developed tests still seem to perform satisfactorily. The prescriptive guidelines put forth in Slaney et al. are therefore better understood as aspirational targets, as recommendations, as challenges for tomorrow's generations of test users and developers, and less like psychometric law.
AdS4 flux vacua in type II superstrings and their domain-wall solutions

We investigate the emergence of supersymmetric negative-vacuum-energy ground states in four dimensions. First, we rely on the analysis of the effective superpotential, which depends on the background fluxes of the internal manifold, or equivalently has its origin in the underlying gauged supergravity. Four-dimensional, supersymmetric anti-de Sitter vacua with all moduli stabilized appear when appropriate Ramond and Neveu-Schwarz fluxes are introduced in IIA. Geometric fluxes are not necessary. Then the whole setup is analyzed from the perspective of the sources, namely D/NS-branes or Kaluza-Klein monopoles. Orientifold planes are also required for tadpole cancellation. The solutions found in four dimensions correspond to domain walls interpolating between AdS4 and flat spacetime. The various consistency conditions (equations of motion, Bianchi identities and tadpole cancellation conditions) are always satisfied, albeit with source terms. We also speculate on the possibility of assigning (formal) entropies to AdS4 flux vacua via the corresponding dual brane systems.
Figurative language processing in atypical populations: the ASD perspective

This paper is intended to provide a critical overview of experimental and clinical research documenting problems in figurative language processing in atypical populations with a focus on the Autistic Spectrum. Research in the comprehension and processing of figurative language in autism invariably documents problems in this area. The greater paradox is that even at the higher end of the spectrum or in the cases of linguistically talented individuals with Asperger syndrome, where structural language competence is intact, problems with extended language persist. If we assume that figurative and extended uses of language essentially depend on the perception and processing of more concrete core concepts and phenomena, the commonly observed failure in atypical populations to understand figurative language remains a puzzle. Various accounts have been offered to explain this issue, ranging from linking potential failure directly to overall structural language competence (Norbury, 2005; Brock et al., 2008) to right-hemispheric involvement (Gold and Faust, 2010). We argue that the dissociation between structural language and figurative language competence in autism should be sought in more general cognitive mechanisms and traits in the autistic phenotype (e.g., in terms of weak central coherence, Vulchanova et al., 2012b), as well as failure at on-line semantic integration with increased complexity and diversity of the stimuli (Coulson and Van Petten, 2002). This perspective is even more compelling in light of similar problems in a number of conditions, including both acquired (e.g., Aphasia) and developmental disorders (Williams Syndrome). This dissociation argues against a simple continuity view of language interpretation.
Teaching Beginning Chess Skills to Students With Disabilities

Keith Storey is an associate professor of education, Chapman University, Concord, CA. Address correspondence to Keith Storey, Chapman University, 2600 Stunwell Drive # I 10, Concord, CA 94520 (e-mail: Storey@Chapman. Edu). hess is an ancient game that is popuC lar all over the world. In some countries, chess instruction in the schools is common because chess requires highlevel thinking skills (e.g., strategy building, problem solving, and spatial thinking) and improves the ability to concentrate. In addition, it provides motivation, independent critical thinking, an increased understanding of cause-effect relationships, patience, and self-reliance (Christiaen & Verholfstadt, 1978; Gelb & Keene, 1997; Horgan, 1987, 1990; Horgan & Morgan, 1990; Reimann, 1994). For example, Frank and D’Hondt (1979) found a statistically significant correlation between the ability to play chess well and spatial, numerical, administrative-directional, and paperwork abilities. Frank and D’Hondt (1979) also found that learning chess had a positive influence on the development of both numerical and verbal aptitudes. Unfortunately, in this country, formal chess instruction is rare in schools. This situation is changing, however, as more and more teachers learn the value of chess instruction (Killigrew, 1998). One of the most important components of educational reform is that of teaching higher order thinking skills (Jones, 1990). This reform focuses on changing the curriculum and on stressing the teaching of skills such as problem solving, critical thinking, and generalization to all students (Meyen, 1995). For students with disabilities, the curriculum should be designed to emphasize higher order thinking skills in addition to practical skills (Grossen, 1991; Leshowitz, 1993). As noted by Smith and Luckasson (l992), many researchers feel that students with disabilities often have poor problem-solving and thinking skills. In other words, they are not strategic learners. To learn efficiently, a student must be proficient in classifying (categorizing and grouping items or concepts together), associating (seeing relationships that exist among and between different knowledge bases), and sequencing (sorting and sequencing by factors such as size, weight, volume, time, and importance). These thinking skills (classifying, associating, and sequencing) help students approach learning tasks more purposefully (Smith & Luckasson, 1992). Chess shows students the rewards of
