Analysis of isothermal annular jets: Comparison of computational fluid dynamics and experimental data
Authors: Moore Eric M. , Shambaugh Robert L. , Papavassiliou Dimitrios V. 
Published: August 2004

AbstractA computational fluid dynamics technique was developed for the simulation of airflow through an annular jet. The technique used a commercial simulation package with a Reynolds stress model for the simulation of turbulent flows. The model parameters were calibrated using available experimental data for circular and annular jets. It was found that, after this calibration, the computational results agreed well with experimental data (specifically, with the velocity magnitude, velocity decay rate, and the velocity spreading rate). The jet geometry studied was based on industrial melt‐blowing nozzles. The velocities studied varied from the low subsonic incompressible range to nearly sonic conditions. Based on both the computational and experimental results, a correlation was proposed that predicts the centerline velocity profiles in both the near‐ and far‐field regions. © 2004 Wiley Periodicals, Inc.

Alkoxysilane‐functionalized acrylic copolymer latexes. I. Particle size, morphology, and film‐forming properties
Authors: Huang Shiqiang , Fan Deqin , Lei Yanqiu , Huang He 
Published: August 2004

AbstractVia the conventional emulsion copolymerization of acrylic monomers and vinyl‐containing alkoxysilane monomers with three siloxane groups, siloxane groups were added to acrylic copolymers to make alkoxysilane‐functionalized acrylic copolymer latexes. In producing stable polymer latexes, seeded polymerization was superior to the other two processes, batch and continuous addition polymerization. The experimental results showed that vinyltriethoxysilane–acrylic copolymer latexes were capable of film forming. In contrast, the incorporation of methacryloxypropyl trimethoxysilane gave rise to the formation of highly crosslinked acrylic copolymer latexes, which had poor film‐forming properties. Relatively small monodispersed particles with particle sizes of less than 100 nm were formed. These particles had a core–shell structure, although some of them were asymmetric. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 94: 954–960, 2004
Investigation of the thermal properties of novel adamantane‐modified polybenzoxazine
Authors: Su Yi‐Che , Chen Wan‐Chun , Chang Feng‐Chih 
Published: August 2004

AbstractTwo novel structures of adamantane‐modified benzoxazines were synthesized from 4‐(1‐adamantyl)‐phenol through the incorporation of adamantane as a pendant group into the polybenzoxazine backbone. Both 1H‐NMR and Fourier transform infrared spectra were used to characterize these structures. The rigid structure of the adamantane tended to hinder the chain mobility (boat anchor effect) and substantially enhanced the thermal properties, including the glass‐transition temperature and decomposition temperature, especially for poly(6‐adamantyl‐3‐methyl‐3,4‐dihydro‐2H‐1,3‐benzoxazine). In the poly(6‐adamantyl‐3‐phenyl‐3,4‐dihydro‐2H‐1,3‐benzoxazine) system, however, the opposite result for the glass‐transition temperature was observed and it was interpreted as lower crosslinking density. The phenyl group was bulkier than the methyl group, and the movement of the molecular chain was hindered between bridging points during the curing process; this resulted in a lower crosslinking density and a lower glass‐transition temperature than those of poly(6‐adamantyl‐3‐methyl‐3,4‐dihydro‐2H‐1,3‐benzoxazine). © 2004 Wiley Periodicals, Inc.

When mitigation evidence makes a difference: effects of psychological mitigating evidence on sentencing decisions in capital trials
Authors: Barnett Michelle E. , Brodsky Stanley L. , Davis Cali Manning 
Published: August 2004

AbstractLittle empirical research has addressed the effects of psychological or psychosocial evidence on sentencing decisions. The present study found that death‐qualified mock jurors were more likely to sentence a defendant to death without mitigating evidence than in a case with mitigating evidence present. Mock jurors were less likely to assign a death sentence in cases that contained one of the following types of mitigating evidence: The defendant was (i) diagnosed with schizophrenia, not medicated, and suffered from severe delusions and hallucinations, (ii) drug addicted and high at the time of the murder, (iii) diagnosed as borderline mentally retarded during childhood, or (iv) severely physically and verbally abused by his parents during childhood.

An analysis of post‐booking jail diversion programming for persons with co‐occurring disorders
Authors: Shafer Michael S. , Arthur Brian , Franczak Michael J. 
Published: August 2004

AbstractFor persons with co‐occurring disorders, interaction with criminal justice systems is a frequent occurrence. As a result, a variety of diversionary programs have been developed nationwide. In this study, a total of 248 individuals with co‐occurring disorders of serious mental illness and substance use disorders who had been arrested and booked on misdemeanor charges participated in a post‐booking jail diversion program in two urban communities. A quasi‐experimental design was used with individuals assigned to diversion or non‐diversion status based upon the decision processes of the mental health–criminal justice systems. The effectiveness of the jail diversion program was evaluated from a variety of sources, including structured interviews, behavioral health service utilization patterns, and criminal justice recidivism patterns. Analyses revealed general main effects for time on many of the outcome variables, with few main effects or interaction effects detected on the basis of diversion status (diverted versus non‐diverted). Across all measures assessing mental health and substance abuse, study participants displayed improvements over time, irrespective of their diversion status or program location. Participants generally displayed no significant changes in their rates of accessibility to, or frequency of use of, the various mental health, substance abuse, and other services, and few changes for diversion status were detected with regard to service utilization. Although a number of indicators of criminality and violence were reduced over time, these reductions were statistically insignificant, with changes for diversionary status or time identified at follow‐up. These results are discussed in light of their implications for jail diversion programming and future research in this area. Copyright © 2004 John Wiley & Sons, Ltd.
Adjusting risk of recidivism: do judicial departures worsen or improve recidivism prediction under the Federal Sentencing Guidelines?
Authors: Krauss Daniel A. 
Published: August 2004

AbstractA limited amount of research exists examining the ability of clinical or intuitive adjustments of formalistic methods of decision‐making to improve upon predictive accuracy beyond that of the original measure. Using receiver operator characteristic (ROC) curves and the departure decisions of federal judges, the recidivism predictive utilities of two measures were compared. The two measures were the Criminal History category, based on the Federal Sentencing Guidelines (a formalistic procedure), and a re‐coded measure of criminal history derived from the sentences actually imposed by judges after they departed from the Guidelines upwards or downwards for recidivism reasons (an adjustment to the formalistic procedure). Both a 10 year post‐sentencing recidivism follow‐up and a 6 year uniform follow‐up period suggested that the Criminal History category performed poorly in predicting recidivism for this offender population, and that judicial departures not only failed to improve, but actually worsened, the predictive accuracy of pre‐departure judgments. Policy implications of the findings are discussed. Copyright © 2004 John Wiley & Sons, Ltd.

Clinical and epidemiologic characteristics of first primary tumors of the central nervous system and related organs among atomic bomb survivors in Hiroshima and Nagasaki, 1958–1995

AbstractBACKGROUNDAnalysis conducted in the Life Span Study (LSS) cohort of atomic bomb survivors in Hiroshima and Nagasaki found a significant dose‐related excess of tumors of the central nervous system (CNS) and the pituitary gland. The objective of the current study was to evaluate clinical and epidemiologic characteristics of first primary tumors of the CNS and the pituitary gland in this cohort and to compare them with characteristics among other populations.METHODSCNS and pituitary gland tumors that were diagnosed between 1958 and 1995 among 80,160 LSS cohort members were ascertained through Hiroshima and Nagasaki tumor registries, autopsy reports, and other sources. Pathologists reviewed all available records and slides to verify histologic diagnoses. Poisson regression analysis was used to model background incidence rates allowing for radiation effects.RESULTSMeningioma was the most common tumor among clinically diagnosed tumors, followed by neuroepithelial tumor, schwannoma, and pituitary tumor. The overall incidence of these tumors increased initially with age but declined among the elderly. For all age groups and for both genders, incidence increased over time. By contrast, when tumors diagnosed at autopsy were included, incidence rose continuously with age and was stable over time.CONCLUSIONSThe main characteristics of CNS and pituitary gland tumors diagnosed in the LSS cohort were consistent with the characteristics of “spontaneous” tumors observed in other population‐based studies. The predominance of meningiomas over neuroepithelial tumors in the Japanese population was noteworthy and warrants further investigation. The secular rise in incidence of all clinically diagnosed CNS and pituitary gland tumors is most likely to be attributable to the increased use of new imaging techniques. Cancer 2004.

An iterative thresholding algorithm for linear inverse problems with a sparsity constraint
Authors: Daubechies I. , Defrise M. , De Mol C. 
Published: August 2004

AbstractWe consider linear inverse problems where the solution is assumed to have a sparse expansion on an arbitrary preassigned orthonormal basis. We prove that replacing the usual quadratic regularizing penalties by weighted 𝓁p‐penalties on the coefficients of such expansions, with 1 ≤p≤ 2, still regularizes the problem. Use of such 𝓁p‐penalized problems withp< 2 is often advocated when one expects the underlying ideal noiseless solution to have a sparse expansion with respect to the basis under consideration. To compute the corresponding regularized solutions, we analyze an iterative algorithm that amounts to a Landweber iteration with thresholding (or nonlinear shrinkage) applied at each iteration step. We prove that this algorithm converges in norm. © 2004 Wiley Periodicals, Inc.
Sharp constants for Moser‐Trudinger inequalities on spheres in complex space ℂn
Authors: Cohn William S. , Lu Guozhen 
Published: August 2004

AbstractThe main results of this paper concern sharp constants for the Moser‐Trudinger inequalities on spheres in complex space ℂn. We derive Moser‐Trudinger inequalities for smooth functions and holomorphic functions with different sharp constants (see Theorem 1.1). The sharp Moser‐Trudinger inequalities under consideration involve the complex tangential gradients for the functions and thus we have shown here such inequalities in the CR setting. Though there is a close connection in spirit between inequalities proven here on complex spheres and those on the Heisenberg group for functions with compact support in any finite domain proven earlier by the same authors [17], derivation of the sharp constants for Moser‐Trudinger inequalities on complex spheres are more complicated and difficult to obtain than on the Heisenberg group. Variants of Moser‐Onofri‐type inequalities are also given on complex spheres as applications of our sharp inequalities (see Theorems 1.2 and 1.3). One of the key ingredients in deriving the main theorems is a sharp representation formula for functions on the complex spheres in terms of complex tangential gradients (see Theorem 1.4). © 2004 Wiley Periodicals, Inc.
On Nonexistence of type II blowup for a supercritical nonlinear heat equation
Authors: Matano Hiroshi , Merle Frank 
Published: August 2004

AbstractIn this paper we study blowup of radially symmetric solutions of the nonlinear heat equation ut = Δu + |u|p−1u either on ℝN or on a finite ball under the Dirichlet boundary conditions. We assume that the exponent p is supercritical in the Sobolev sense, that is,

We prove that if ps < p < p*, then blowup is always of type I, where p* is a certain (explicitly given) positive number. More precisely, the rate of blowup in the L∞ norm is always the same as that for the corresponding ODE dv/dt = |v|p−1v. Because it is known that “type II” blowup (or, equivalently, “fast blowup”) can occur if p > p*, the above range of exponent p is optimal.We will also derive various fundamental estimates for blowup that hold for any p > ps and regardless of type of blowup. Among other things we classify local profiles of type I and type II blowups in the rescaled coordinates. We then establish useful estimates for the so‐called incomplete blowup, which reveal that incomplete blowup solutions belong to nice function spaces even after the blowup time. © 2004 Wiley Periodicals, Inc.
Synthesis, Structural Characterization and Properties of Copper(II) and Zinc(II) Coordination Polymers with a New Bridging Chelating Ligand
Authors: Yong Guo‐Ping , Wang Zhi‐Yong , Cui Yong 
Published: August 2004

AbstractTwo new coordination polymers [Cu3(cpida)2(H2O)4]n·4nH2O (1) and [Zn(Hcpida)]n·nH2O (2) have been synthesized with a new bridging chelating ligand N‐(4‐carboxyphenyl)iminodiacetic acid (H3cpida). X‐ray diffraction analysis reveals that complex 1 consists of 1D parallelogram‐shaped molecular‐box chains constructed from unusual linear trinuclear CuII secondary building units (SBUs), which further extend into 2D layers by perfect parallel AA stacking. Complex 2 adopts a 2D framework comprised of tetrahedral ZnII centres isolated from each other by the bridging bidentate carboxylate groups of the Hcpida2− ligands. Compound 2 possesses alternate open and closed channels along the a direction. The dehydation and rehydration experiments showed that compound 2 undergoes a reversible inclusion process to some extent. However, the removal of guest water molecules from 1 results in the collapse of the polymeric networks owing to the loss of the coordinated water molecules. Compound 2 also shows strong photoluminescence and may be a good candidate for a photoactive or porous material. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
Double Catalytic Activation with Chiral Lewis Acid and Amine Catalysts
Authors: Kanemasa Shuji , Ito Kennosuke 
Published: August 2004

AbstractAn effective enantioselective synthetic method based on a new concept of double catalytic activation has been developed, in which both electrophile and nucleophile precursors are activated by use of catalytic amounts of chiral Lewis acid and amine base, respectively. This method has been successfully applied to enantioselective thiol conjugate additions, as well as to Michael reactions of malononitrile, nitromethane, and cyclic 1,3‐dicarbonyl compounds in the presence of DBFOX/Ph − nickel(II) aqua complexes with amines. This new method should be a powerful tool, especially when single catalytic activation of either nucleophiles or electrophiles is not sufficient to induce bond formation.
