Comparison of smallest eigenvalues and extremal points for third and fourth order three point boundary value problems.
… positive eigenvalues is obtained. These results are then extended to the nth order problem using two different methods. One method involves finding the Green's function for –u⁽ⁿ⁾ = 0 satisfying the higher order boundary conditions, and the other involves making a substitution that allows us …

A topological generalization of Schwarz' lemma
… But a geometrical interpretation of Zorn*s results is impossible without severe additional restrictions on the space and the families of transformations. The present paper proves a geometrical version of Schwarz' lemma by metrical-topological methods. The proof is applicable to the euclidean KL …

Born-Oppenheimer Corrections Near a Renner-Teller Crossing
… the parameter originally used by Renner. For 0 < bË < 1, we prove self-adjointness of the leading order Hamiltonian, that it has purely discrete spectrum, and that its eigenfunctions and their derivatives decay exponentially. Perturbation theory and finite difference calculations suggest that …

Numerical and Analytical Analysis of Vortex Induced Vibrations of a Pipeline Close to Seabed
… that the proposed model is validated. The results show that the numerical results seem to match the experimental data broadly and the model is fairly robust.<br/><br/>Moreover, to further understand the proposed model, the analytical solutions are obtained and analysed. To get the analytical …

The Prevalence of Temporomandibular Disorder in African Americans
… pilot study collected a convenience sample of adult residents of the Dallas, Texas metropolitan area to estimate the prevalence of temporomandibular disorder (TMD) in African Americans. Additionally, the study also collected the same data on Caucasians for comparisons against the African American …

Climate change information and analyst expectations
… this discussion into security prices. Results suggest analysts’ incorporation of climate information remains nascent and we should exercise caution in assuming analysts broadly incorporate climate-related information. My findings add to our understanding of how market participants process …

Design of Asymmetric Slope Fractional Band Reject Filters
… of designing asymmetric-slope band reject filters. Two new non-conventional transfer functions are presented based on the concept of fractional Laplacian operator, s^(α) where 0 < α < 1. It is possible to achieve asymmetric slopes, large values of notch magnitude up to 90 dB and high Q values …

Hypermaps: constructions and operations
… construct those hypermaps, and we extend the result<br/>to nonorientable hypermaps.<br/><br/>A classification of all operations of finite order in oriented hypermaps is<br/>given, and a detailed study of one of these operations (the duality operation)<br/>is developed. Adapting the notion of …

RF wave observations in beam-plasma discharge
The Beam Plasma. Discharge (BPD) has been produced in the large vacuum chamber at Johnson Space Center (2 x 3 m) using an energetic electron beam of moderately high perveance (K ~ 1.4 x 1^-6 A V^-3/2). A more complete expression of the threshold current IC taking into account the pitch angle …

Predictive role of fresh and post-selection total motile sperm count in the success of autologous and oocyte-donor ICSI cycles [Ruolo predittivo del numero totale di spermatozoi mobili su campione fresco e post-selezione nel successo dei cicli ICSI autologhi e con ovodonazione]
… l’ICSI, che teoricamente dovrebbero superare molte delle limitazioni legate al fattore maschile. Tuttavia, la letteratura mostra risultati eterogenei riguardo al reale impatto dei parametri seminali sugli esiti clinici, suggerendo la necessità di individuare indicatori più sensibili. In questo …

A Bayesian approach to computing Brauer groups of cubic surfaces
… of X and a confidence level > r for the result. The algorithm runs by sampling lifts of Frobenius at many primes of good reduction and relies on Chebotarev’s density theorem and Bayesian inference to produce, with confidence level > r, a subgroup of the Weyl group of E_6. This subgroup …

Fasciola hepatica cystatins: recombinant production, biochemical characterisation and efficacy as vaccines
Fasciolosis, resulting from infection with the digenetic trematode (flatworm) Fasciola hepatica, is of major global economic importance in ruminants, such as cattle and sheep, and is now recognised as an important zoonosis. Following ingestion by the mammalian host, the parasite migrates through …

Quaternary Silver Bismuth Chalcogenide Halides Ag - Bi - Q - X (Q = S, Se; X = Cl, Br): Syntheses and Crystal Structures
… the degree of substitution of Bi by Ag with 1/2 <= x <= 1. Their structures are built up from two alternating types of modules denoted A and B that are stacked parallel to (001). In module A, rows of edge-sharing [MZ6] octahedra (Z = X and/or Q); M = Ag and/or Bi) running parallel to [010] …

Identification of Two Novel Genome-Wide Significant Single Nucleotide Polymorphisms, associated with Barrett’s Oesophagus, determined by further Replication of a Genome-Wide Association Study
Barrett's oesophagus (BE) is a common premalignant condition to oesophageal adenocarcinoma (EAC). A previous genome-wide association study (GWAS) identified BE susceptibility Single Nucleotide Polymorphisms (SNPs) on chromosome 6p21, within the HLA region, and16q23, where the closest protein-coding …

The role of Marine Renewable Energy structures and biofouling communities in promoting self-sustaining populations of Non-Native Species
Novel environments and biological communities created by the large-scale deployment of Marine Renewable Energy Devices (MREDs) have the potential to promote the spread of non-native species (NNS). Knowledge of how community composition resident on MREDs is shaped by geography, local hydrodynamics …

The Design and Analysis of Reliable Communication Networks
In this study, a communication network is represented by a graph, and the problem of designing a network that will operate as reliably as possible is investigated. Failure of the network is associated with the removal of a set of nodes which disconnects the graph or by the removal of a set of edges …
