Patient-controlled analgesia at the end of life at a pediatric oncology institution.

Background Patient controlled anesthesia (PCA) is increasingly used to manage pain in pediatric cancer patients and is important in the treatment of escalating pain at the end of life. The description of the use of opioid PCA in this population has been limited.
Diverse strategies targeting α7 homomeric and α6β2* heteromeric nicotinic acetylcholine receptors for smoking cessation

Preclinical studies suggest that a diversity of nicotinic acetylcholine receptors (nAChRs) with different sensitivities to nicotine may contribute to tobacco addiction. Using rodent intravenous nicotine self-administration as a preclinical model with good predictive validity for therapeutic efficacy for tobacco cessation, investigators have identified heteromeric α6β2* and homomeric α7 nAChRs as promising novel therapeutic targets to promote smoking abstinence (*denotes possible assembly with other subunits). The data suggest that diverse strategies that target these subclasses of nAChRs, namely inhibition of α6β2* nAChRs and stimulation of α7 nAChRs, will support tobacco cessation. α6β2* nAChRs, members of the high-affinity family of β2* nAChRs, function similarly to α4β2* nAChRs, the primary target of the FDA-approved drug varenicline, but have a much more selective neuroanatomical pattern of expression in catecholaminergic nuclei. Although activation of β2* nAChRs facilitates nicotine self-administration, stimulation of α7 nAChRs appears to negatively modulate both nicotine reinforcement and β2* nAChR function in the mesolimbic dopamine system. Although challenges and caveats must be considered in the development of therapeutics that target these nAChR subpopulations, an accumulation of data suggests that α7 nAChR agonists, partial agonists, or positive allosteric modulators and α6β2* nAChR antagonists, partial agonists, or negative allosteric modulators may prove to be effective therapeutics for tobacco cessation.
Use of Statistics From National Data Sources to Inform Rehabilitation Program Planning, Evaluation, and Advocacy:

Data on people with disabilities can be used to confirm service needs and to evaluate the resulting impact of services. Disability statistics from surveys and administrative records can play a meaningful role in such efforts. In this article, the authors describe the array of available data and statistics and their potential uses in rehabilitation service planning and evaluation. They discuss the 2000 Decennial Census Long Form, the American Community Survey, the National Health Information Survey, the National Health Information Survey on Disability, the Current Population Survey Annual Demographics Survey, the Survey of Income and Program Participation, and the Health and Retirement Survey, administrative records such as the Rehabilitation Services Administration (RSA) 911 and the Social Security Administration (SSA) Title 2 and Title 16 records, and matched data such as linked RSA and SSA records. They also provide examples of applications of these data sets to rehabilitation service planning and evalu...
Graduate medical education financing: Effect of the balanced budget act of 1997

Summary The Balanced Budget Act of 1997 limits the number of house staff that will be funded by Medicare in a given hospital (exceptions are allowed, but with penalties). It also provides an incentive for hospitals to reduce the number of house staff trained since they will be funded on a 3-year rolling average and it reduces IME payments by 29% over 5 years.
Constraints on r-process nucleosynthesis in accretion disks

Systems in which accretion drives an outflow from a region near a compact object may enrich the interstellar medium in r-process elements. A detailed assessment of the efficacy of this mechanism for the r-process is presented here, taking into account the constraints imposed by typical accretion-disk conditions. It is concluded that r-process elements are unlikely to have been made in this way, largely because the total production is too low, by a factor of about 100,000, to explain the observed abundances.
Analysis of a Composite Piezoelectric Circular Plate With Initial Stresses for MEMS

The paper presents a mechanical analysis of the multi-layer circular composite plate For MEMS devices. Each layer of the plate is assumed to have different radius, material properties and initial stresses. Governing equations for the composite plate are derived based on the classical laminated plate theory, and analytical soultions have been developed for static deflection of the initially stressed plate due to transverse pressure loading as well as for a given electric field in the piezoelectric layer. A nonlinear finite elernent analysis of the plate is also performed. The analytical result match the FE results for the range of parameters used in the microphone design. The analytical model will be useful in the design and optimization of MEMS devices containing circular piezoelectric composite plates and diaphragms.Copyright © 2002 by ASME
A comprehensive analysis of group scheduling heuristics in a job shop cell

This paper describes a broad-based simulation study of the performance of two-stage group scheduling heuristics in a job shop cell. The objective of this study was to examine the direct and interactive effects of a variety of shop factors on the performance of the best, previously reported, group scheduling heuristics. A set of traditional single-stage scheduling heuristics were examined as well. Shop factors considered include: setup to runtime ratio, cell load level and variability of inter-arrival times. An assumption common to group scheduling research which provides for an equal division of the part family into subfamilies is also examined. This is accomplished through the creation of an alternative scenario where the majority of the parts are assigned to one subfamily, i.e. one subfamily dominates the part family population. The effects of set up to runtime ratio and cell load have been examined in previous group scheduling research, but not in conjunction with the inter-arrival time variability fac...
A Rhetorical Response to Hurricane Katrina

It begins with a reaction to the initial depictions of Katrina, continues with a discussion of the use of symbols to socially construct its aftermath, and concludes with key questions that the strengths of rhetorical theory allow the critic to ask and answer.
Hereditary Crooked Toes in Chickens

Abstract The prevalence of a morphological defect known popularly as crooked or curly toes is apparently increasing to a considerable extent in poultry flocks. This is indicated by requests for information regarding the defect, appearing in the popular poultry press. Persons requesting this information are usually interested to know if birds with crooked toes should be used for breeding purposes. Most answers have indicated that it is safe to do so, stating that the defect was caused by a riboflavin deficiency or due to managemental factors such as smooth, slick floors, crowding under hovers, etc. The object of this note is to bring forth evidence that while the two types of crooked toes mentioned above are of undoubted occurrence there is still another type, determined genetically, which is indistingusihable from that due to managemental factors. Figure 1a shows the expression in a relatively mild form while Figure 1b shows a more . . .
Stiff Eyes in Stiff-Person Syndrome

The clinical findings of stiff-person syndrome (SPS) include trunk and limb muscle stiffness and paroxysmal cramps. Antibodies directed against glutamic acid decarboxylase (GAD) has been associated with SPS. We report a patient with SPS and anti-GAD antibodies (antiGAD-Abs) with a prominent supranuclear gaze palsy and bradykinesia mimicking progressive supranuclear palsy (PSP). ### Case report. A 45-year-old former fighter pilot presented with an 18-month history of stiffness and gait problems that began with several falls backwards while training for a marathon. Six months later, she noted stiffness of the left arm and leg. She reported painful back and limb spasms when startled by touch. Her history was notable for pernicious anemia. Examination (video) including head thrust revealed a supranuclear vertical gaze palsy and vertical greater than horizontal saccade hypometria with prolonged saccade latency. Vertical pursuits were saccadic, but horizontal pursuits were normal. Convergence was impaired. She had a mildly masked facies, asymmetrically increased axial and limb tone, bradykinetic gait and limb movements, and no arm swing while walking. The remainder of the examination was unremarkable. Brain and spinal cord MRI scans showed mild cortical atrophy. EMG showed continuous motor activity at rest, normal 3-Hz repetitive stimulation, and a mild sensory neuropathy. CT of the chest, abdomen, and pelvis were normal. An extensive evaluation including …

Estimation of Biomass Heat Storage Using Thermal Infrared Imagery: Application to a Walnut Orchard

A new method to estimate tree biomass heat storage from thermal infrared (TIR) imaging of biomass surface temperature is presented. TIR images of the canopy are classified into trunk, branches, and leaves. The one-dimensional heat equation in cylindrical coordinates is forced with trunk and branch surface temperatures to simulate the temperature distribution and heat storage in tree trunks and branches. Assuming uniform leaf temperatures, heat storage in leaves is computed from the surface temperature of the leaves separately for the sunlit upper and shaded lower canopy. The sum of trunk, branches, leaf, and air heat storage gives the canopy heat storage. Measurements in a walnut orchard near Davis, California, in early June 2007 showed that biomass heat storage was of the same order as air heat storage and about 1% of daytime and 9% of nighttime net radiation.
A comparison of cyanobacterial bloom dynamics in freshwater, estuarine and marine environments

Abstract Cyanobacterial blooms are diagnostic of accelerating eutrophication in freshwater (FW) and estuarine (E) ecosystems. In full salinity marine (M) ecosystems blooms are more closely controlled by physical than trophic conditions. FW and E blooms are initiated and exacerbated by (1) excessive nutrient (N and P) loading. (2) high surface water temperatures (> 20°C). (3) persistent water column stratification. (4) long water residence time. and (5) organic matter enrichment. Physical–chemical forcing features can act synergistically to control bloom potential. Factors additionally favouring cyanobacterial blooms include (1) low dissolved inorganic carbon concentrations (especially in FW), (2) low total and dissolved N: P ratios. (3) close metabolic coupling between sediments and water column, and (4) high irradiance, long daylength. FW and E blooms are closely controlled by hydrodynamic and salinity alterations. The ability of nuisance taxa (nuisance characteristics include hypoxia and anoxia, toxicit...

Hydrogen and helium spectra in large magnetic fields

The energy levels and wave functions of hydrogen and helium atoms in the presence of large (∼107G) magnetic fields are found by assuming that the eigenvalues and eigenvectors may be approximated by those of a truncated Hamiltonian matrix. In these atoms, fields of this size produce, in addition to the usual Paschen-Back effect, a quadratic Zeeman effect. This contributes an upward shift to the energy of all levels, which at sufficiently high fields dominates the Paschen-Back splitting. The behavior of a number of eigenvalues and wave functions as a function of magnetic field is presented. The effects of the field on the wavelengths and strengths of the components of Hβ and the helium lines λλ 4471, 4026 and 4120 as well as the forbidden λ 4025 are examined. In hydrogen the lines are split into components attributed to the now nondegenerate transitionsnlm l→n′l′m′l. In helium forbidden lines are excited, which may develop strengths larger than those of the allowed lines.
Proton dose calculation based on in-air fluence measurements

Proton dose calculation algorithms—as well as photon and electron algorithms—are usually based on configuration measurements taken in a water phantom. The exceptions to this are proton dose calculation algorithms for modulated scanning beams. There, it is usual to measure the spot profiles in air. We use the concept of in-air configuration measurements also for scattering and uniform scanning (wobbling) proton delivery techniques. The dose calculation includes a separate step for the calculation of the in-air fluence distribution per energy layer. The in-air fluence calculation is specific to the technique and—to a lesser extent—design of the treatment machine. The actual dose calculation uses the in-air fluence as input and is generic for all proton machine designs and techniques.
Synthesis and characterization of macroporous chitosan/calcium phosphate composite scaffolds for tissue engineering

Chitosan scaffolds reinforced by beta-tricalcium phosphate (beta-TCP) and calcium phosphate invert glass were fabricated with a low-cost, bioclean freeze-drying technique via thermally induced phase separation. The microstructure, mechanical performance, biodegradation, and bioactivity of the scaffolds were studied. The composite scaffolds were macroporous, and the pore structures of the scaffolds with beta-TCP and the glass appeared very different. Both the compressive modulus and yield strength of the scaffolds were greatly improved, and reinforced microstructures were achieved. The bioactivity tests showed a continuous decrease in both Ca and P concentrations of a simulated body fluid (SBF) after the scaffolds with beta-TCP were immersed in the SBF for more than 20 h, which suggests that an apatite layer might be formed on the scaffolds. However, the same was not observed for the pure chitosan scaffolds or the scaffolds incorporated with the glass. This was further confirmed by micrographs from scanning electron microscopy. This study suggests that the desirable pore structure, biodegradation rate, and bioactivity of the composite scaffolds might be achieved through controlling the ratio of chitosan and calcium phosphates or beta-TCP and the glass.
Effect of Chemisorbed Water on the Magnetic Quenching of Orthopositronium in Silicon Dioxide Powders

Positron-annihilation angular-correlation measurements have been made on compressed pellets of powdered Si${\mathrm{O}}_{2}$. The results show an anomolously strong magnetic quenching of orthopositronium which disappears with the removal of chemisorbed water.
Planar coupler devices of multimode fiber optics

In this paper we report on investigations of the multimode planar approach to fiber-optic coupler development. The planar approach, which utilizes photolithographic processing, is promising because of its versatility and high reproducibility. Our results indicate that this approach is indeed versatile and may lead to potential savings over conventional fabrication techniques. However, the major problem that remains to be solved is the reduction of interface losses.
On partially conserved currents

Abstract It is observed that the hypothesis of partially conserved leptonic weak interaction currents, which has been proposed by several authors, implies that the fundamental meson-baryon interaction be invariant under a certain group constructed from these currents. The only candidate for this group that is consistent with experiment and that does not require the introduction of an exorbitant number of spinless mesons is the eight-dimensional rotation group. The associated meson-baryon coupling is one first proposed by Gursey. This group does not seem to have any connection with the approximate symmetries of the strong interactions; thus we reject the notion of partially conserved currents.
Study of mask corner rounding effects on lithographic patterning for 90-nm technology node and beyond

This paper presented an integrated simulation framework linking our in-house mask writer simulator and the optical lithography simulation engines to include the mask corner rounding effect in lithographic performance evaluations. In the writer simulator, a modified two-dimensional Gaussian function is used as the functional form of the convolution kernel (point spread function). Parameters of the kernel function for different writing machines are automatically extracted from scanning electron microscope (SEM) photographs of simple mask pattern geometries. The convolution results of the kernel and the mask layout form the intensity distribution for pattern definition. The isocontour of the resulting image at the desired level of bias can be regarded as a good approximation of the mask shape obtained from a real mask writer. The writer simulator then saves the contour data as the user-specified format of mask file for subsequent lithography simulations. With the aid of this simulation tool, the impacts of mask corner rounding effects on two-dimensional OPCed pattern for 90-nm and 65-nm node lithography processes are quantitatively evaluated. The results show the line end shortening (LES) is greatly influenced by mask corner rounding effects. The LESs in the 65-nm node process are over twice of those in the 90-nm node process. The resolution capability of a 2-stage 16X mask manufacturing process was also studied in this paper. Simulation results indicate the ArF lithography might be required to make this innovative mask-making technology suitable for 90-nm generation and beyond.
The Pathogenesis of Eosinophilic Esophagitis: Beyond the Eosinophil

Over the past two decades, eosinophilic esophagitis (EoE) has undergone a remarkable transformation. What used to be a rare, case-reportable condition about which little was known, is now widely recognized as an important cause of upper GI morbidity and the subject of intense research activity. The clinical syndrome has been defined, treatment trials have been performed, and guidelines for diagnosis and management have been published.[1] In parallel with this has been a rapid increase in our understanding of the pathogenesis and genetic basis of EoE.[2–5] While the consensus is that EoE is an allergic/immune-mediated condition in which the eosinophil plays a central role, recent data suggest that ‘non-eosinophil cell types’ play important, and possibly crucial, roles as well. The allergic basis for the disease is based on several lines of evidence. Patients with EoE have a high burden of concomitant atopic conditions,[6–10] allergen-free elemental diets cause nearly universal improvement in symptoms and resolution of eosinophilia,[11, 12] and there is a seasonal variation in EoE, possibly due to aeroallergens.[10, 13–16] Prompted by the review by Zhang and colleagues in this issue of Digestive Diseases and Sciences,[17] this editorial summarizes the role of the eosinophil and several other cell types in the pathogenesis of EoE, including lymphocytes, mast cells, fibroblasts, and epithelial cells. Recognizing and characterizing the role of the non-eosinophil cell types is likely to be central to future advances in the diagnosis and treatment of EoE.
Assessment of algal farm designs using a dynamic modular approach

Abstract The notion of renewable energy provides an important mechanism for diversifying an energy portfolio, which ultimately would have numerous benefits including increased energy resilience, reduced reliance on foreign energy supplies, reduced GHG emissions, development of a green energy sector that contributes to economic growth, and providing a sustainable energy supply. The conversion of autotrophic algae to liquid transportation fuels is the basis of several decades of research to competitively bring energy-scale production into reality; however, many challenges still remain for making algal biofuels economically viable. Addressing current challenges associated with algal production systems, in part, requires the ability to assess spatial and temporal variability, rapidly evaluate alternative algal production system designs, and perform large-scale assessments considering multiple scenarios for thousands of potential sites. We introduce the development and application of the Algae Logistics Model (ALM) which is tailored to help address these challenges. The flexible nature of the ALM architecture allows the model to: 1) interface with external biomass production and resource assessment models, as well as other relevant datasets including those with spatiotemporal granularity; 2) interchange design processes to enable operational and economic assessments of multiple design configurations, including the integration of current and new innovative technologies; and 3) conduct trade-off analysis to help understand the site-specific techno-economic trade-offs and inform technology decisions. This study uses the ALM to investigate a baseline open-pond production system determined by model harmonization efforts conducted by the U.S. Department of Energy. Six sites in the U.S. southern-tier were sub-selected and assessed using daily site-specific algae biomass productivity data to determine the economic viability of large-scale open-pond systems. Results show that costs can vary significantly depending on location and biomass productivity and that integration of novel dewatering equipment, order of operations, and equipment scaling can also have significant impacts on economics.
Advancements in the selective inhibition sintering process development

Selective inhibition sintering (SIS) is a new layer-based rapid prototyping process that fabricates parts by joining polymer powder particles in the part's body to form a coherent solid and by preventing particles from joining at the part's boundary to form edges. This paper presents the fundamentals of the SIS process, its dedicated path generator, material selection research and the application of response surface methodology which has led to optimum performance, given various factors affecting part strength, surface quality and dimensional accuracy.
Male calling behavior, female discrimination and acoustic interference in the Neotropical treefrog Hyla microcephala under realistic acoustic conditions

Anuran choruses are acoustically complex assemblages of calling males. Little is known about the behavior of males or females in such natural sound environments. I studied calling behavior of males of Hyla microcephala in nature by using an interactive computer-based system that allowed me to simulate call interruptions by a number of males. I also monitored the calling behavior of groups of four to six males. When a male is interrupted by the call of another frog, he increases the spacing between the notes of his call. Responses of this kind are strongest to the loudest neighbor, and some males may ignore interruptions by all but a single close male. Interruptions using synthetic calls with silent gaps indicated that males respond vocally to reductions in sound intensity as brief as 20 ms. This ability helps to explain how males can rapidly alternate notes during pairwise interactions. Amounts of acoustic overlap between pairs of males in the choruses were usually below 10% of an individual's total calling time during bouts. The time a male spent calling that was free of acoustic interference by any other male ranged from 34–92% of his total calling time. When group size was decreased, this unobstructed calling time increased. Previous research showed that females of H. microcephala discriminate against calls that overlap so that the call pulse-train structure is degraded. Here I show that a 6 dB difference in intensity between the overlapped calls is sufficient to reduce the degradative effect of call interference. Females were also given a choice between interfering calls broadcast from two adjacent and two widely separated speakers. An angular separation between speakers of 120° was insufficient to elicit a preference for the separated sources. Together, data on behavior of males and females indicated that males actively reduce acoustic interference with those loud individuals most likely to degrade seriously the temporal structure of their calls.
The addition of hydrogen atoms to diacetylene and the heats of formation of i-C4H3 and n-C4H3.

In this article, we discuss in detail the addition of hydrogen atoms to diacetylene and the reverse dissociation reactions, H + C{sub 4}H{sub 2} {leftrightarrow} i-C{sub 4}H{sub 3} (R1) and H + C{sub 4}H{sub 2} n-C{sub 4}H{sub 3} (R2). The theory utilizes high-level electronic structure methodology to characterize the potential energy surface, Rice-Ramsperger-Kassel-Marcus (RRKM) theory to calculate microcanonical/J-resolved rate coefficients, and a two-dimensional master-equation approach to extract phenomenological (thermal) rate coefficients. Comparison is made with experimental results where they are available. The rate coefficients k{sub 1}(T, p) and k{sub 2}(T, p) are cast in forms that can be used in chemical kinetic modeling. In addition, we predict values of the heats of formation of i-C{sub 4}H{sub 3} and n-C{sub 4}H{sub 3} and discuss their importance in flame chemistry. Our basis-set extrapolated, quadratic-configuration-interaction with single and double excitations (and triple excitations added perturbatively), QCISD(T), predictions of these heats of formation at 298 K are 130.8 kcal/mol for n-C{sub 4}H{sub 3} and 119.3 kcal/mol for the i-isomer; multireference CI calculations with a nine-electron, nine-orbital, complete-active-space (CAS) reference wavefunction give just slightly larger values for these parameters. Our results are in good agreement with the recent focal-point analysis of Wheeler et al. (J.more » Chem. Phys. 2004, 121, 8800-8813), but they differ substantially for {Delta} H{sub f 298}{sup 0}(n-C{sub 4}H{sub 3}) with the earlier diffusion Monte Carlo predictions of Krokidis et al.« less
Alcohol skin preparation causes surgical fires

INTRODUCTIONSurgical fires are a rare but serious preventable safety risk in modern hospitals. Data from the US show that up to 650 surgical fires occur each year, with up to 5% causing death or serious harm. This study used the National Reporting and Learning Service (NRLS) database at the National Patient Safety Agency to explore whether spirit-based surgical skin preparation fluid contributes to the cause of surgical fires. METHODSThe NRLS database was interrogated for all incidents of surgical fires reported between 1 March 2004 and 1 March 2011. Each report was scrutinised manually to discover the cause of the fire. RESULTSThirteen surgical fires were reported during the study period. Of these, 11 were found to be directly related to spirit-based surgical skin preparation or preparation soaked swabs and drapes. CONCLUSIONSDespite manufacturer's instructions and warnings, surgical fires continue to occur. Guidance published in the UK and US states that spirit-based skin preparation solutions should co...

A LABORATORY INVESTIGATION OF ALTERNATIVE TRANSFER PRICING MECHANISMS.

Abstract In this study, we conduct a laboratory experiment to evaluate three alternative mechanisms for pricing transfers between a buyer and a seller. The three mechanisms are: (1) a direct negotiation mechanism with which either party suggests terms of trade that the other can accept or reject; (2) a traditional mechanism where the transfer price and quantity are determined by the intersection of the reported demand and supply schedules of the buyer and seller, respectively; and (3) the Ronen-McKinney mechanism which computes the transfer quantity in the same way as the traditional mechanism, but is designed to give different transfer prices to the buyer and seller in order to induce them to truthfully report their respective schedules. For all periods of the experiment, the direct negotiation mechanism is the least efficient of the three due to the high frequency of bargaining impasses. The efficiency of the traditional mechanism and the efficiency of the Ronen-McKinney mechanism are indistinguishable from one another. However, in the last four periods of the experiment where the data exhibit less volatility, the efficiencies of all three mechanisms are indistinguishable from each other. When truthful reporting is considered, the Ronen-McKinney mechanism had the least amount of misreporting followed by the traditional mechanism and then the direct negotiation mechanism.
An amino‐terminal lysine residue of rat connexin40 that is required for spermine block

Spermine blocks connexin40 (Cx40) gap junctions, and two cytoplasmic amino-terminal domain glutamate residues are essential for this inhibitory activity. To further examine the molecular basis for block, we mutated a portion of a basic amino acid (HKH) motif on the Cx40 amino-terminal domain. Replacement of the Cx40 H15 + K16 residues with the Q15 + A16 sequence native to spermine-insensitive connexin43 (Cx43) gap junctions increased the equilibrium dissociation constant (Kd) and reduced the maximum inhibition by spermine. The corresponding electrical distance (δ) approximation was decreased by about 50%. The transjunctional voltage (Vj)-dependent gating of homotypic Cx40 H15Q + K16A mutant gap junctions was also significantly reduced. The minimum normalized steady-state junctional conductance (Gmin) increased from 0.17 to 0.72, with an increase in the half-inactivation voltage from 48 to 60 mV. However, the unitary junctional conductance (γj; 160 pS) was only slightly altered, and the relative cation/anion conductance and permeability ratios were unchanged from wild-type Cx40 gap junction channels. The relative K+/Cl− permeability (PK/PCl) ratio increased from six to ten when [KCl] was reduced to 25% of normal. These data suggest that the HKH motif at positions 15–17 is important to the conformational structure of the putative voltage sensor and spermine receptor of Cx40, without causing significant alteration of the electrostatic surface charge potentials that contribute to the ion selectivity of this gap junction channel.
Illuminator design for the printing of regular contact patterns

Abstract Diffraction patterns of two different contact arrays of 0.32 μm pitch are investigated using the AIMS TM tool and analyzed using Fourier analysis. We introduce a simple method to analytically predict the pupil pattern for an arbitrary periodic mask feature. A circular illuminator is split up into components that produce varying amount of interference at the wafer plane and it is shown that contrast can be enhanced by excluding certain parts of this illuminator. The optimized illuminator depends only on stepper parameters and mask geometry.
Thespian: using multi-agent fitting to craft interactive drama

There has been a growing interest in designing multi-agent based interactive dramas. A key research challenge faced in the design of these systems is to support open-ended user interaction while ensuring dramatic user experiences and consistent character personalities. Autonomous agents with reactive and planning abilities are well suited for realizing characters that both adapt to user interactions and are consistent with their own goals. However, agents are often created manually and with extensive programming effort, that excludes authoring by non-technical authors. Thespian is a framework for realizing interactive drama that seeks to reduce programming effort. To start, an author provides linear scripts of the drama. An automated fitting algorithm then configures agents to behave according to the scripts via automated tuning of goal parameters. This capability allows authors to design in a familiar way by writing scripts. Thespian also supports reuse of characters and story elements. Given these advantages, new scenarios can be developed with less programming effort. We discuss the use of Thespian in fitting characters in the Tactical Language Training System and in a Grimms' fairy tale. We also present preliminary experiments on migrating characters between these stories.
Evolving concepts regarding transient ischemic attacks

Transient ischemic attack (TIA) represents one end of the spectrum of focal brain ischemia, the other being completed infarction or ischemic stroke. The evolving technologic advancements in neuroimaging continue to change and sharpen the definition, epidemiology, and management of TIA. As a powerful risk factor for ischemic stroke, TIA deserves widespread public and physician education, urgent attention and investigation, and rapid management. The recognition and treatment of TIA provides an excellent opportunity for stroke prevention that is often missed or poorly recognized among physicians.
Use of analytic expressions for the calculation of equilibrium distributions of polycyclic aromatic hydrocarbons in benzene flames

The thermodynamic properties of twenty isomer groups in six series of benzenoid polycyclic aromatic hydrocarbons and first members of seven higher series have been used to explore their thermodynamic stabilities in a near-sooting benzene flame studied by Bittner and Howard. Since the thermodynamic properties of isomer groups are linear in carbon number within a homologous series, analytic expressions for the equilibrium distribution can be used. On the basis of the assumption that the successive isomer groups in an homologous series are formed from benzene by the addition of acetylene and the production of molecular hydrogen, equilibrium distributions of isomer groups within six series have been calculated at various heights in this flame. The competition between these six isomer groups and the first members of higher series up to circumcircumcoronene (C 96 H 24 ) has been studied by calculating equilibrium partial pressures. These calculations show that the first members of series above coronene remain very stable at levels above 8 mm, where C 10 H 8 , C 14 H 10 , and C 16 H 10 decline for thermodynamic reasons. These calculations show the usefulness of isomer group properties and emphasize the simplifications resulting from the linear dependence of the standard Gibbs energies of formation on carbon number. They also show the usefulness of calculations based on observed partial pressures of acetylene, molecular hydrogen, and benzene.
The consequences of acculturation to service delivery and research with Hispanic families

The experience of working with Hispanic children and their parents is compared with the existing professional literature. Although the literature acknowledges partially the importance of acculturation, the consequences of acculturation to service delivery and working with Hispanics as research subjects are seldom addressed. These consequences are demonstrated in four areas: as a cause of family problems, in the attitudes of Hispanics toward speaking Spanish and English, in the status of folk healers in the Hispanic community, and in attitudes toward the delivery of human services. The failure to take into account the consequences of acculturation can contribute to the further underutilization of mental health services by Hispanic families.
Central generation of swimming activity in the hydrozoan jellyfish Aequorea aequorea

Swimming in Aequorea is controlled by a network of electrically coupled neurons (swim motorneurons) located in the inner nerve ring. The network is made up of the largest neurons in the ring, up to 22 μm in diameter. Intracellular recordings from swim motorneurons reveal slow membrane potential oscillations and a superimposed barrage of synaptic “noise.” The synaptic noise, but not the slow oscillations, is eliminated in seawater containing an elevated Mg++ concentration. The swim motorneurons produce a rapid burst of two to eight action potentials preceding each contraction of the subumbrella. Spontaneous bursting persists in high-Mg++ seawater. Injected ramp currents indicated a “bursty” character of the swim motorneurons as suprathreshold depolarizations produced repetitive bursting with an increasing burst frequency with increased depolarization. Hyperpolarizing currents locally blocked spiking in swim motorneurons. Intercellular coupling was demonstrated with Lucifer Yellow injection and dual electrode recordings. In dye fills, only the large neurons of the inner nerve ring were dye-coupled. Two pieces of evidence suggest that swim motorneurons activate the overlying epithelial cells via chemical synapses. First, direct synaptic connections have been noted in ultrastructural examination of the inner nerve ring region. Second, dual recordings from a swim motorneuron and an epithelial cell reveal a 1:1 correspondence between neuron spikes and epithelial synaptic potentials. The synaptic potentials occur with a latency as short as 3 ms which is constant in any one recording session. The results suggest that the swim motorneuron network of Aequorea not only performs a motorneuron function, but also serves as the pattern generator for swimming activity.
Fracture processes in polymeric materials. V. Dependence of the ultimate properties of poly(methyl methacrylate) on molecular weight

The influence of molecular weight on the fracture surface energy, Young's modulus, tensile strength, and inherent flaw size in poly(methyl methacrylate) has been determined. In common with other mechanical properties, the dependence of the fracture surface energy on molecular weight can be represented by γ = A – (B/M), where M is the molecular weight, and A and B are arbitrary constants. By extrapolation, the upper limiting value is 1.55 × 105 ergs/cm.2, while the surface energy, and hence the tensile strength, should become zero for a polymer of molecular weight 25,000. This value is in good agreement with that found directly from brittle strength measurements.
Small sample properties of estimators in the autocorrelated error model: a review and some additional simulations

This paper provides a review of the literature concerning estimation in time series regression with first-order autocorrelated disturbances. Some additional simulation results confirm that the Cochrane-Orcutt estimator should not be used to correct for autocorrelation whether the explanatory variable is trended or not. Preferred estimators include a Bayesian estimator, full maximum likelihood and the iterative Prais-Winsten estimator.
Sequential chemotherapy and irradiation in advanced stage endometrial cancer: A Gynecologic Oncology Group phase I trial of doxorubicin-cisplatin followed by whole abdomen irradiation.

Abstract Objectives The optimal treatment regimen for advanced stage endometrial carcinoma (EC) is yet to be established. The objective of this study was to evaluate the feasibility and toxicity of delivering sequential doxorubicin–cisplatin (AC) followed by whole abdomen irradiation (WAI). Methods Patients with stage III/IV EC with 2 each) followed by WAI plus para-aortic and/or true pelvic boost. Outcome objectives were feasibility of the regimen, acute toxicity and chronic irradiation toxicity monitored for at least one year after completing treatment. Results Thirty-one patients were entered onto the study. Twenty-nine were evaluable for feasibility of the regimen, and 22 patients were evaluable for chronic radiation toxicity with a median follow-up of 21 months. Three patients (14%) experienced severe chronic toxicity including one treatment-related death. The five-year progression-free survival (PFS) and overall survival (OS) was 52.5% and 60.1% respectively. Conclusions The results from the first stage of this study found this regimen of sequential AC followed by WAI eligible for further study. Although toxicity was not excessive at the time of completion of the first stage, there was insufficient interest by the Gynecologic Oncology Group to continue study of this regimen; therefore, a conclusion regarding feasibility and chronic toxicity in an expanded cohort as initially intended is not possible. The risk of recurrence in advanced EC is sufficiently high that may warrant further investigation of sequential chemotherapy and WAI.
Continuous rational functions on real and $p$-adic varieties

This note studies, and partially solves, 3 elementary questions about continuous rational functions on real (and p-adic) algebraic varieties: Can one restrict such a function to a subvariety? Can one extend such a function from a subvariety? Which linear equations can be solved using such functions?
IMPROVED ANALYSIS OF TIME‐RESOLVED SINGLE PHOTON COUNTING FLUORESCENCE DATA OF EXCIMER/EXCIPLEX SYSTEMS USING A DUAL ANALYSIS ITERATED RECONVOLUTION PROGRAM ON A DEDICATED LABORATORY MICROCOMPUTER

A novel iterative reconvolution program for the simultaneous analysis of two sets of time-resolved single photon counting (TRSPC) fluorescence data is described. Each set of data may be fit to a function containing up to three exponential terms and any of the parameters may be constrained to both sets. This dual analysis approach offers great advantages for the study of a coupled photokinetic scheme such as an excimer or exciplex system, both in terms of the accuracy of the results and in the simplicity and speed of the analysis.
Nickel Thin Film Coatings on Steels with Electroless Plating and Sputter Deposition

Nickel thin films were coated on steel substrates applying both electroless plating and sputter deposition techniques. The deposition rates and thin film properties including crystal structures, microhardness, scratch resistance, and cross section microstructures were determined. The coating thickness of electroless nickel followed a parabolic rate relationship with time whereas that of sputter deposited nickel varied linearly with time. For up to I μm coating thickness, the rate of electroless plating is about ten times as fast as that of sputter deposition under the experimental conditions of this study. X-ray diffraction analysis showed that sputter deposited Ni had clear crystallinity and electroless plated Ni was amorphous. The microhardness of sputter deposited Ni is higher than that of electroless plated Ni. Scratch tests of coated steel showed that adhesion of electroless nickel coatings was superior to that of sputter deposited nickel.

Structural design using a wind tunnel test program and a risk analysis

Abstract A wind study procedure is presented that is compatible with the level of risk criteria used in ANSI A58.1 (1982). This procedure uses wind tunnel results and a risk analysis to select design wind forces. The uncertainty analysis requires the estimation of the mean, coefficient of variation and probability density function for all random variables.
Design and experimental verification of real-time mechanisms for middleware for networked control

Networked control systems give rise to several new problems which need to be resolved for successful development of such control systems. One of the most important is to develop a software framework with appropriate architecture and mechanisms for rapid, reliable, and evolvable distributed control applications. In particular, timeliness in the interaction among entities which constitute the overall control loop is one of the crucial requirements that must be provided by the platform. We discuss the issues related to the design and implementation of such mechanisms to support timeliness requirements. We describe the design of real-time enhancements to Etherware, a middleware for distributed control systems that has been developed in the Information Technology Convergence Laboratory at the University of Illinois. We further evaluate the performance of the designed middleware through a distributed inverted pendulum control application. We demonstrate the satisfactory performance of the unstable system even under several sophisticated run-time functionalities such as component upgrade and migration. We demonstrate that stability is maintained even under each of these tests as well as a computational stress test.
A macroscopic model for plastic flow in metal-matrix composites

Abstract A micromechanically based continuum model is developed to analyze the enhancement of plastic properties of particulate-reinforced metal-matrix composites over matrix materials. The composite is idealized as uniformly distributed periodic arrays of unit cells. Each unit cell consists of a rigid inclusion surrounded by a plastically deforming material. An energy method is adopted to obtain the overall constitutive relation for the composite on the basis of the local nonuniform deformation fields. Effects of particle volume fractions and shapes (e.g. whiskers, discs, etc.) as well as the matrix properties on the flow properties of the composite are obtained. The results are in good agreement with experimental observations and finite element analyses found in the literature. An explicit expression is also proposed, providing a means for evaluating various factors affecting the strength of composites.
