Technical aspects of dielectric spectroscopy measurements of liquid crystals
Authors: Perkowski P. , Łada D. , Ogrodnik K. , Rutkowska J. , Piecek W. , Raszewski Z. 
Published: May 2008

AbstractThe dielectric spectroscopy measurements were performed for antiferroelectric liquid crystalline mixture. For this purpose, the cells with ITO electrodes were prepared. It was found that it is not possible to detect some important relaxation modes in Sm A*, Sm C*, and Sm CA* phases. The own cell mode (related to cell properties, i.e., capacity and resistivity) covers the dielectric response of liquid crystalline medium. Dielectric measurements in cells with gold electrodes were done to show all possible relaxations in antiferroelectric liquid crystals (LCs).

Trinomial random walk with one or two imperfect absorbing barriers
Authors: El-Shehawey M. 
Published: May 2008

Abstract
Trinomial random walk, with one or two barriers, on the non-negative integers is discussed. At the barriers, the particle is either annihilated or reflects back to the system with respective probabilities 1 − ρ, ρ at the origin and 1 − ω, ω at L, 0 ≤ ρ,ω ≤ 1. Theoretical formulae are given for the probability distribution, its generating function as well as the mean of the time taken before absorption. In the one-boundary case, very qualitatively different asymptotic forms for the result, depending on the relationship between transition probabilities and the annihilation probability, are obtained.
On generalized measures of entropy and dependence
Authors: Kumar Parmil , Hooda D. 
Published: May 2008

Abstract
Various authors have studied extensions of Shannon’s entropy but their inferential properties and applications in applied sciences have not invited proper attention from researchers. In the present paper we explore the motivation and implication of using various classes of the generalized entropies and conditional entropies. We evaluate β-class and (α, β)-class entropies for multivariate normal density function. We also obtain the measures of dependence in terms of the classes of generalized entropies.
Responses of native and invasive plant species to selective logging in anAcacia koa‐Metrosideros polymorphaforest in Hawai'i
Authors: Friday James B. , Scowcroft Paul G. , Ares Adrian 
Published: May 2008

AbstractQuestions:Is the introduced timber speciesFraxinus uhdeiinvasive in Hawai'i? Has logging disturbance facilitated the spread ofFraxinusand other alien species?Location:Windward Mauna Kea, island of Hawai'i.Methods:We surveyed 29 plots which were established before selective logging of the native treeAcacia koain 1971 to determine ifFraxinusspread beyond the borders of an existing plantation and if other alien species increased. We created gaps in the canopy of theFraxinusplantation and measured seed rain and regeneration, and we sampled foliar and soil nutrients inside and around the plantation.Results:Basal area ofFraxinusincreased from 0.7 m2.ha‐1in 1971 to 10.8 m2.ha‐1in 2000.Fraxinuswas not found in plots that were located more than 500 m from those where it occurred in 1971 except along a road. Basal area ofAcacia koadecreased after logging but subsequently recovered. Occurrence of the alien vinePassiflora tarminianaand alien grassEhrharta stipoidesdecreased. Seedling regeneration ofFraxinuswas prolific in gaps but did not occur under the canopy. Basal area ofFraxinusdid not correlate with soil nutrient concentrations.Conclusions:Fraxinuswas able to regenerate following logging more rapidly than native tree species. Basal area growth ofFraxinuswas great enough to offset a decline in native trees and cause an increase in forest productivity. If theFraxinusplantation is harvested, managers should plan ways of favoring regeneration of the nativeAcaciawhich is more valuable both for timber and for conservation.

ContextChildren and adults with psychopathic traits and conduct or oppositional defiant disorder demonstrate poor decision making and are impaired in reversal learning. However, the neural basis of this impairment has not previously been investigated. Furthermore, despite high comorbidity of psychopathic traits and attention-deficit/hyperactivity disorder, to our knowledge, no research has attempted to distinguish neural correlates of childhood psychopathic traits and attention-deficit/hyperactivity disorder.ObjectiveTo determine the neural regions that underlie the reversal learning impairments in children with psychopathic traits plus conduct or oppositional defiant disorder.DesignCase-control study.SettingGovernment clinical research institute.ParticipantsForty-two adolescents aged 10 to 17 years: 14 with psychopathic traits and oppositional defiant disorder or conduct disorder, 14 with attention-deficit/hyperactivity disorder only, and 14 healthy controls.Main Outcome MeasureBlood oxygenation level–dependent signal as measured via functional magnetic resonance imaging during a probabilistic reversal task.ResultsChildren with psychopathic traits showed abnormal responses within the ventromedial prefrontal cortex (Brodmann area 10) during punished reversal errors compared with children with attention-deficit/hyperactivity disorder and healthy children (P &amp;lt; .05 corrected for multiple comparisons).ConclusionsTo our knowledge, this study provides the first evidence of abnormal ventromedial prefrontal cortex responsiveness in children with psychopathic traits and demonstrates this dysfunction was not attributable to comorbid attention-deficit/hyperactivity disorder. These findings suggest that reversal learning impairments in patients with developmental psychopathic traits relate to abnormal processing of reinforcement information.
Fabrication and Dielectric Characterization of Advanced BaTiO3/Polyimide Nanocomposite Films with High Thermal Stability
Authors: Dang Zhi‐Min , Lin You‐Qin , Xu Hai‐Ping , Shi Chang‐Yong , Li Sheng‐Tao , Bai Jinbo 
Published: May 2008

AbstractBarium titanate/polyimide (BaTiO3/PI) nanocomposite films with high dielectric permittivity (20), high breakdown strength (67 MV m−1), and high thermal stability are prepared by an in‐situ polymerization process. A very thin polymer layer (about 5 nm) is coated on the surface of nanosized BaTiO3 particles to form a core–shell‐like structure, which can guarantee homogeneous dispersion of the BaTiO3 particles in the PI matrix. It is confirmed that the core–shell‐like structure originates from both the electrostatic attraction between the precursor poly(amic acid) (PAA) and the BaTiO3 particles and the hydrogen bond interaction between PI and the BaTiO3 particles. Such a structure also has some influence on the dielectric properties and breakdown strength of films. After casting and degassing of the sticky film, the dielectric permittivity of the nanocomposite film is close to or even higher than that of submicrocomposite films, which is attributed to the advanced interfacial structure between the BaTiO3 and PI phases.
Evaluation of a clinic‐based cholinesterase test kit for the Washington State Cholinesterase Monitoring Program

Published: May 2008

AbstractBackgroundThe Washington State Cholinesterase Monitoring Program for pesticide handlers requires blood draws at local clinics, with samples tested at a central laboratory. At present, workers with inhibited cholinesterase activity may be re‐exposed before they can be removed from work. In this study we explored the option of on‐site testing at local clinics using the EQM Test‐mate Kit™, a portable cholinesterase test kit.MethodsTest kit cholinesterase activity measurements were performed on 50 blood samples by our research staff, and compared to measurements on the same samples by the Washington State Public Health Laboratory. Another set of samples was also analyzed with the test kit by medical staff at an eastern Washington clinic.ResultsTriplicate measurements with the test kit had a 3.3% average coefficient of variation (CV) for plasma cholinesterase (PChE), and a 3.5% average CV for erythrocyte cholinesterase (AChE) measurements. The kit's PChE measurements were similar to PHL measurements (average ratio of 0.98) when performed in the laboratory, but had a tendency to underestimate activity when used in the clinic setting (average ratio of 0.87). The kit systematically overestimated AChE activity by 42–48% relative to the PHL measurements, regardless of where the samples were analyzed.ConclusionsThis easy‐to‐use test kit appeared to be a viable method for clinic‐based PChE measurements, but was less consistent for AChE measurements performed in the clinic. Absolute measurements with the kit need to be evaluated carefully relative to standardized methods. Am. J. Ind. Med. 51:532–538, 2008. © 2008 Wiley‐Liss, Inc.
Gas Storage in Nanoporous Materials
Authors: Morris Russell E. , Wheatley Paul S. 
Published: May 2008

AbstractGas storage in solids is becoming an ever more important technology, with applications and potential applications ranging from energy and the environment all the way to biology and medicine. Very highly porous materials, such as zeolites, carbon materials, polymers, and metal‐organic frameworks, offer a wide variety of chemical composition and structural architectures that are suitable for the adsorption and storage of many different gases, including hydrogen, methane, nitric oxide, and carbon dioxide. However, the challenges associated with designing materials to have sufficient adsorption capacity, controllable delivery rates, suitable lifetimes, and recharging characteristics are not trivial in many instances. The different chemistry associated with the various gases of interest makes it necessary to carefully match the properties of the porous material to the required application.
Atraumatic complex transradial intervention using large bore sheathless guide catheter
Authors: Mamas M.A. , Fath‐Ordoubadi F. , Fraser D.G. 
Published: May 2008

AbstractThe Asahi sheathless guide catheter system is a hydrophilic catheter with a central dilator that does not require an introducer sheath during transradial percutaneous coronary intervention. Conventional sheath introducers are often 1‐ to 2F larger than the catheter itself; therefore, this system enables the use of a larger French catheter during procedures than would otherwise be possible using conventional techniques. We describe the use of a 7.5F sheathless guide catheter system with a smaller outer diameter than a conventional 6F introducer sheath in 16 cases performed transradially involving rotablation, crush stent bifurcation lesions, 7F proximal protection, and thrombectomy devices. Such cases would otherwise not always be possible if performed using conventional transradial techniques in patients with smaller radial artery sizes. © 2008 Wiley‐Liss, Inc.
