Morphologic responses of osteoblast-like cells in monolayer culture to ELF electromagnetic fields.

Osteoblast-like cells (MC 3T3-E1) were exposed for 24 h, immediately after plating, to a 60 Hz, 0.7 mT rms magnetic flux density, sufficient to induce an electric field of 0.5 mV/m rms, in order to investigate the influence of ELF field exposure on cell morphology. Using phase contrast images of the live cells, computerized image-analysis permitted rapid and objective quantification of cell length, width, area, perimeter, circularity and angular orientation. While the field-exposed cells were consistently smaller than sham treated cells, the morphologic alterations were not significantly different in the exposed cell population when cell orientation was not considered. When analyzed with respect to cell orientation, cells oriented parallel to the induced electric field (orthogonal to the applied magnetic field) demonstrated a significant decrease in cell length and an increase in roundness. These results confirm and extend previous studies on the morphologic adaptation of cells to low level ELF electromagnetic fields. The results suggest that the observed responses most likely depend on the induced electric field, with a field intensity threshold well below 1 mV/m. Further, these results provide important clues to the specific mechanism by which such low level fields may be capable of influencing cell behavior, and help to explain some of the difficulties in obtaining robust responses in in vitro EMF experiments.
Modifying parent‐child interactions in a disadvantaged family

Abstract An economically disadvantaged toddler, identified by a health care facility as evidencing developmental lag, was involved in a preventively oriented behavioral intervention. The program focused on identifying and modifying deficit mother‐child interactional patterns. Over the course of the seven session home intervention, considerable increases were noted in the child's compliance to parental requests and parental use of praise. Important ancillary changes included increases in frequency of child vocalizations and improvements in cognitive development.
Seasonal variability in response ofIps pini (Coleoptera: Scolytidae) to ipsdienol in New York.

In May,Ips pini in New York did not respond in the field to 50–98.5% (R)-(−)-ipsdienol (synthetic). In September, beetles responded strongly to 50–60% (R)-(−)-ipsdienol (synthetic). In May and June, New York beetles showed marked preference for their own males over Arizona males, which produce an average of 94.1% (R)-(−)-ipsdienol. This suggested that ipsdienol stereochemistry alone does not ensure activity and that an additional compound is necessary for attraction in May. In the second year of field tests, attraction to synthetic ipsdienol and male beetles was tested in the spring, summer, and fall. There was response only to males in the spring and mid-summer and to both males and synthetic ipsdienol in the late summer and fall, causing a significant treatment x sampling period (date) interaction. Laboratory-reared beetles were not significantly more attracted to ipsdienol than to a blank airstream in laboratory assays, while male volatiles were significantly more attractive than ipsdienol and the blank. These data demonstrate that there is one or more unknown semiochemicals necessary for pheromonal response and that the behavioral activity of synthetic ipsdienol varies seasonally.
A unified approach to IFIR filter design using B-spline functions

An efficient procedure is presented for the design of interpolated finite impulse response (IFIR) filters with linear phase. The algorithm uses the uniform B-spline function as an interpolator and solves the optimal Chebyshev approximation problem on the appropriate subinterval. The technique can be used for the design of general low-pass, high-pass and bandpass filters. Although the number of multiplications of the IFIR filter is dependent on the bandwidth and the center frequency of the desired filter, this approach nearly always provides a substantial reduction in complexity when compared to other FIR and IFIR design procedures. >
Widespread and extensive lengthening of 3′ UTRs in the mammalian brain

Remarkable advances in techniques for gene expression profiling have radically changed our knowledge of the transcriptome. Recently, the mammalian brain was reported to express many long intergenic noncoding (lincRNAs) from loci downstream from protein-coding genes. Our experimental tests failed to validate specific accumulation of lincRNA transcripts, and instead revealed strongly distal 3' UTRs generated by alternative cleavage and polyadenylation (APA). With this perspective in mind, we analyzed deep mammalian RNA-seq data using conservative criteria, and identified 2035 mouse and 1847 human genes that utilize substantially distal novel 3' UTRs. Each of these extends at least 500 bases past the most distal 3' termini available in Ensembl v65, and collectively they add 6.6 Mb and 5.1 Mb to the mRNA space of mouse and human, respectively. Extensive Northern analyses validated stable accumulation of distal APA isoforms, including transcripts bearing exceptionally long 3' UTRs (many >10 kb and some >18 kb in length). The Northern data further illustrate that the extensions we annotated were not due to unprocessed transcriptional run-off events. Global tissue comparisons revealed that APA events yielding these extensions were most prevalent in the mouse and human brain. Finally, these extensions collectively contain thousands of conserved miRNA binding sites, and these are strongly enriched for many well-studied neural miRNAs. Altogether, these new 3' UTR annotations greatly expand the scope of post-transcriptional regulatory networks in mammals, and have particular impact on the central nervous system.
New tests of the universality of free fall.

We use a continuously rotating torsion balance to make new tests of the universality of free fall (UFF). We study differential accelerations of Be-Cu and Be-Al test-body pairs in the fields of Earth, the Sun, our Galaxy, and in the direction of the cosmic microwave dipole. We also compare the acceleration towards the Sun and our galactic center of Cu and single-crystal Si in an Al shell (this pair of bodies approximates the elemental compositions of Earth's core and the Moon or Earth's crust, respectively). In terms of the classic UFF parameter \ensuremath{\eta}, our Earth-source results are \ensuremath{\eta}(Be,Cu)=(-1.9\ifmmode\pm\else\textpm\fi{}2.5)\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}12}$ and \ensuremath{\eta}(Be,Al)=(-0.2\ifmmode\pm\else\textpm\fi{}2.8)\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}12}$ where all errors are 1\ensuremath{\sigma}. Thus our limit on UFF violation for Be and a composite Al/Cu body is \ensuremath{\eta}=(-1.1\ifmmode\pm\else\textpm\fi{}1.9)\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}12}$. Our solar-source results are \ensuremath{\Delta}a(Be,Cu) =(-3.0\ifmmode\pm\else\textpm\fi{}3.6)\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}12}$ cm/${\mathrm{s}}^{2}$, \ensuremath{\Delta}a(Be,Al)=(+2.4\ifmmode\pm\else\textpm\fi{}5.8)\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}12}$ cm/${\mathrm{s}}^{2}$, and \ensuremath{\Delta}a(Si/Al,Cu)=(+3.0 \ifmmode\pm\else\textpm\fi{}4.0)\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}12}$ cm/${\mathrm{s}}^{2}$. This latter result, when added to the lunar laser-ranging result that senses both composition-dependent forces and gravitational binding-energy anomalies, yields a nearly model-independent test of the UFF for gravitational binding energy at the 1% level.
Comparing Analytic Techniques to Classify Dyadic Relationships: An Example Using Siblings

Several methods exist for typologizing dyadic relationships. The present study reviews the utility of methods for typologizing relationships, exploring the strengths and weaknesses of 3 different approaches, and applying them to the study of adolescent sibling relationships. The 3 methods examined are a priori methods, cluster analysis, and mixture models. Each approach was used to analyze the same data taken from a cross section of a longitudinal study of 384 families with adolescent children. Clustering appeared to favor a 2-type solution whereas the mixture model approach supported 4 types. The 3 strategies are discussed in terms of their statistical rigor and utility in the study of close relationships.
Therapeutic remodeling of myeloma chromatin

Multiple myeloma cells dysregulate critical oncogenes and tumor suppressor genes by a number of mechanisms. In addition to genetic changes, there are less well-studied epigenetic changes that can result in the silencing of tumor suppressor genes and contribute to disease progression. These heritable
On conditions for self-healing in distributed software systems

This paper attempts to identify one of the necessary conditions for self-healing, or self-repair, in complex systems, and to propose means for satisfying this condition in heterogeneous distributed software. The condition identified here is the following: For a system with a wide and open range of possible configurations to be self healing, it must possess suitable regularities, which can be relied upon to be satisfied by all possible configurations of the system, and which must be invariant of its failures. We observe that self-healing in physical artifacts, as well as in biological systems, are largely based on regularities engendered by the laws of nature. But since laws of nature have no effective sway over the behavior of software, we propose means for imposing artificial laws over a given distributed system, which are designed to induce desired regularities in them. We demonstrate the efficacy of the proposed approach by applying it to a simple example of electronic purchasing in enterprise systems.
Analysis of substrate thermal gradient effects on optimal buffer insertion

This paper studies the effects of the substrate thermal gradients on the buffer insertion techniques. Using a non-uniform temperature-dependent distributed RC interconnect delay model, the buffer insertion problem is analyzed and design guidelines are provided to ensure the near-optimality of the signal performance in the presence of the thermal gradients. In addition, the effect of temperature-dependent driver resistance on the buffer insertion is studied. Experimental results show that neglecting thermal gradients in the substrate and the interconnect lines can result in non-optimal solutions when using standard buffer insertion techniques and that these effects intensify with technology scaling.

Conflict in Business-to-Business e-Commerce (B2B): A Study of B2B Relational Structure and Perceptions of Conflict, Power, and Relationship Success

This field study investigates how the relational structure of business-to-business (B2B) e-commerce relationships affects perceptions of conflict, power, and success in e-commerce relationships. Data from interviews with employees in 82 U.S. organizations reveal that employees in community-oriented B2B structures perceive themselves as experiencing more process conflict than do employees in buyer/supplier-oriented structures. Also, employees in community-oriented B2B structures perceive more organizational power. Furthermore, the B2B e-commerce relational structure was found to moderate the relationship between perceived organizational power and the number of reported conflict incidents. Specifically, in buyer/supplier structures, power differences were associated with low conflict and in community-oriented structures power differences were associated with high levels of conflict.
Power harvesting for low power wireless sensor network

This paper presents a design of an inset fed square patch array and singly fed rectangular stacked patch array operating in the 2.45 GHz ISM band for RF energy harvesting. The goal of the design is to harness and store energy from the surrounding environment which can be used in wireless sensor nodes (WSN). On the basis of simulation results obtained by FEKO simulation software, the VSWR, return loss, radiation pattern, gain all meet the design requirements. Results show that dc voltage of 0.2167 V and 0.2203 V can be achieved at ≈−31.8 dBW received energy level from single layer and stacked array designs respectively at 2.45 GHz IEEE 802.11b band. This would correspond to potential working distance of 6m in both cases.
The Social Contexts of Focus Groups

This article argues that focus group discussions are shaped by multiple social contexts, a fact that is often ignored by researchers. Using data from a focus group study of the effects of violence on everyday life, this article provides an analysis of four such contexts: the associational, status (especially gender), conversational, and relational contexts. These multiple and overlapping contexts foster both problematic silences (lack of disclosure) and problematic speech (strategic shaping of comments) in group discussions. These processes limit the usefulness of focus groups as a tool for understanding individual thoughts, feelings, or experiences. However, they make focus groups an excellent site for analyzing the processes of social interaction. The article concludes with suggestions for improving the implementation and interpretation of focus groups in light of this analysis.
Analysis of a class of cluster-based multiprocessor systems

In this thesis, a cluster-based multiprocessor system is described. Analytical modeling techniques have been developed to compute the cluster-based system reliability. The bandwidth availability is analytically evaluated for uniform and favorite memory references. The results obtained for the cluster-based system are compared with those of the crossbar and multiple-bus systems for the same values of system parameters. The cluster-based system reliability and bandwidth availability are enhanced by proposing a slight modification of the cluster-based system architecture; and the reliability and bandwidth availability of the modified system are analytically evaluated showing the resulting enhancement due to the proposed modification. The cluster-based system reduces the network complexity by employing two levels of hierarchy. However, a number of levels greater than two may be needed in systems that have a large number of processors and memory modules, since the goal is to reduce the network complexity without losing much of the performance. The hierarchy of the cluster-based system is extended to any arbitrary number of levels m by introducing a generalized class of m-level hierarchical multiprocessor systems. This system is equivalent to the well-known crossbar system when there is no hierarchy (m = 1), and to the cluster-based system when the number of levels equals two (m = 2). The performance of the m-level hierarchical multiprocessor system is analyzed in terms of the system bandwidth for both hierarchical nonuniform reference (H N R) and uniform reference (U R) models. The results show that for higher rate of local requests the m-level system performs fairly closely to the crossbar system and outperforms a typical multiple-bus system (with the number of buses equal to half the number of processors). The bandwidth of the m-level system is evaluated for different values of m and the results are compared with those of a crossbar system (m = 1). Finally, expressions are derived for the reliability and the bandwidth availability of the m-level hierarchical multiprocessor system for any arbitrary number of levels m for H N R and U R models. The reliability and bandwidth availability results obtained for the m-level system are compared with those of the crossbar and multiple-bus systems.

The Influence of Mining and Human Immunodeficiency Virus Infection Among Patients Admitted for Retreatment of Tuberculosis in Northern Tanzania.

Abstract. In tuberculosis (TB)–prevalent settings, patients admitted for retreatment of TB may account for a high burden of poor treatment outcome. We performed a retrospective cohort study to characterize retreatment patients and outcomes at a TB referral hospital in northern Tanzania. From 2009 to 2013, 185 patients began a retreatment regimen, the majority for relapse after prior treatment completion. Men accounted for an unexpected majority (88%), 36 (20%) were human immunodeficiency virus (HIV) infected and for 45 (24%) mining was their primary occupation. A poor outcome (death, default, or persistent smear positivity after 7 months of treatment) was found in 37 (23%). HIV infection was the only significant predictor of poor outcome (adjusted odds ratio [aOR] = 2.50, 95% confidence interval [CI] = 1.07–5.83, P = 0.034). Interventions to minimize need for retreatment or improve retreatment success may be regionally specific. In our setting, community-based diagnosis and management among at-risk subpopulations such as miners and those HIV infected appear of highest yield.
Are three colonies of Neostromboceros albicomus, a candidate biological control agent for Lygodium microphyllum, the same host biotype?

ABSTRACTThree colonies of Neostromboceros albicomus, a candidate biological control agent of Lygodium microphyllum, were barcoded using the D2 expansion domain, to determine which of two biotypes they represented. The first colony, collected in 2005 and 2007, was used for the initial host range testing. Colonies collected in 2012 and 2014 are currently being used to finalise this testing. All three colonies were collected in Trat Province, Thailand and all three populations show identical sequences to the N. albicomus biotype which prefers L. microphyllum as its host plant. The N. albicomus biotype that uses L. flexuosum as its host plant differs by a single nucleotide, a difference which may reflect cryptic speciation.
Solid state 13C NMR analysis of vulcanized rubbers. XVI. The competitive vulcanization of natural rubber and polybutadiene blends

Abstract Solid state 13C NMR was used to study the competitive vulcanization of blends of natural rubber and high cis polybutadiene. A NMR sampling technique utilizing the stacked homopolymers was developed that helps to determine the spectral differences occurring due to competitively vulcanizing an elastomer blend. The small amount of interfacial crosslinking was expected to be undetectable but has been tentatively observed. Concentration of crosslinks at the interface may occur from limited solubility of curative species in both rubbers. The NMR spectra also showed inhibition of cis-trans isomerization in natural rubber with addition of polybutadiene.

Continuity in General Nonconvex Economies (with Applications to the Convex Case)

There are numerous instances in economics where nonconvexities are inherent to the problem at hand. The obvious cases are those of increasing marginal rates of substitution and increasing returns in the Arrow-Debreu model (cf. Starr [7], Arrow-Hahn [1]). Nonconvexities are also inherent in transactions (Heller [4], Heller-Starr [6]) and in models of optimal taxation with administrative cost (Heller-Shell [5]). Nonconvexities also arise in the theory of externalities (Starrett [8]).
Hormone glucagon: electrooxidation and determination at carbon nanotubes

The oxidation of glucagon, which is one of the key hormones in glucose homeostasis, was studied at electrodes modified with carbon nanotubes (CNT) that were dispersed in a polysaccharide adhesive chitosan (CHIT). Such electrodes displayed improved resistance to fouling, which allowed for the investigation of both the electrolysis/mass spectrometry and electroanalysis of glucagon. The off-line electrospray ionization and tandem mass spectrometric analyses showed that the -4 Da mass change to glucagon upon electrolysis at CNT was due to the electrooxidation of its tryptophan (W25) and dityrosine (Y10, Y13) residues. The methionine residue of glucagon did not contribute to its oxidation. The amperometric determination of glucagon yielded the limit of detection equal to ∼20 nM (E = 0.800 V, pH 7.40, S/N = 3), sensitivity of 0.46 A M(-1) cm(-2), linear dynamic range up to 2.0 μM (R(2) = 0.998), response time <5 s, and good signal stability. Free tryptophan and tyrosine yielded comparable analytical figures of merit. The direct amperometric determination of unlabeled glucagon at CHIT-CNT electrodes is the first example of a rapid alternative to the complex analytical assays of this peptide.
Feasibility Study of an Electronic Interface Between Internet-Based Survivorship Care Plans and Electronic Medical Records.

Purpose:Survivorship care plans (SCPs) are recommended for all cancer survivors. Myriad barriers to implementation exist. This study was performed to evaluate the feasibility of interface development between an SCP and an electronic medical record (EMR).Methods:An information technology application was developed to extract data from the EMR in use at our center (Epic). Data were transferred to autopopulate an Internet-based tool for creation of SCPs (LIVESTRONG Care Plan) that had been previously used for the creation of more than 35,000 plans.Results:Data (demographic characteristics, surgeries, chemotherapy drugs, radiation site) were extracted from the EMR and transferred to the care plan platform, without transfer of protected health information. Care plans were created and transferred back to the EMR. During clinical testing, SCPs were created by nurse practitioners during scheduled clinic visits for 146 sequential, eligible patients (67% breast cancer, 33% colorectal cancer). All patients received c...
Collection development in partnership with youth: Uncovering best practices

Young people represent a significant portion of public and school library users, so collection development policies and procedures should involve these constituents, particularly with the advent of technology. Youth information needs can be culled from circulation and demographic statistics, student work, surveys, and interviews. Selection criteria should be reviewed in light of student input. Issues of access vs. ownership highlight ways that youth can help select online resources, and aid in their effective use. Student work itself constitutes an innovative part of the collection. Finally, student advisory boards can systematically help develop and maintain responsive collections.
Third-Order Nonlinear Optical Effects in Organic Polymeric Films

This paper presents some recent theoretical and experimental work carried out in the author’s laboratory on the nonlinear optical properties of organic polymers. The ab initio SCF theory has been used with the finite field method to calculate the third order nonlinearity of conjugated structures in order to understand the effect of conjugation and the role of substituents. Experimental studies of third order resonant nonlinearlty in polythiophenes and cumylphenoxy phthalocyanine, the latter in the form of Langmuir-Blodgett films, are presented using femtosecond degenerate four wave mixing.
Combined Tight-Binding and Numerical Electrodynamics Understanding of the STEM/EELS Magneto-optical Responses of Aromatic Plasmon-Supporting Metal Oligomers

The optical-frequency magnetic and electric properties of cyclic aromatic plasmon-supporting metal nanoparticle oligomers are explored through a combination of scanning transmission electron microscopy (STEM)/electron energy-loss spectroscopy (EELS) simulation and first-principles theory. A tight-binding-type model is introduced to explore the rich hybridization physics in these plasmonic systems and tested with full-wave numerical electrodynamics simulations of the STEM electron probe. Building from a microscopic electric model, connection is made at the macroscopic level between the hybridization of localized magnetic moments into delocalized magnetic plasmons of controllable magnetic order and the mixing of atomic pz orbitals into delocalized π molecular orbitals of varying nodal structure spanning the molecule. It is found that the STEM electrons are uniquely capable of exciting all of the different hybridized eigenmodes of the nanoparticle assembly—including multipolar closed-loop ferromagnetic and a...
Microgrid and Its Application in Earthquake Prevention and Disaster Reduction

Microgrid offers a new idea to solve the technical challenge brought by the interconnection of distributed generation and reduce the affects of natural disaster such as earthquake on power grid. In this paper the concept of microgrid and present situation of the research in this field home and abroad are described. Based on the materials related to the lessons from the Hanshin Earthquake occurred in Japan in the year of 1995 that is released by the Cabinet Office of Japan and the empirical research situation of emergency disaster prevention system in the earthquake early warning system of Japan, and taking the demonstration project of regional energy supply system in Etchujima Campus of Tokyo University of Marine Science and Technology for example, the role that microgrid could play in the energy supply for earthquake refuge is expounded. Finally, the key topics of microgrid to be researched in depth in the application of earthquake prevention and disaster reduction are summarized.
The myth: in vivo degradation of polypropylene-based meshes

Polypropylene is a base polymer used in biomaterial applications, including sutures and mesh products, for the treatment of pelvic organ prolapse, stress urinary incontinence, and hernia repairs. Previous studies have dismissed the value of formulation additives employed in polypropylene, and the importance and necessity of an effective mesh explant cleaning protocol when characterizing explanted devices. However, both are critical to understanding the alleged degradation of polypropylene-based meshes. An effective, nondestructive, hydrolytic cleaning process, supplemented with light microscopy (LM), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) data, was used to evaluate 78 explanted Prolene meshes (with duration of implantation ranging from 0.4 to 11.7 years). The cleaning process exposed clean, unoxidized, nondegraded Prolene fibers with smooth surfaces and with no visible evidence of gradient-type or ductile damage. LM showed identical translucent and sometimes clear, cracked/flaking material on both blue and clear fibers, instead of clear cracked/flaking material on the clear fibers and blue cracked/flaking material on the blue fibers. FTIR confirmed progressive protein removal and loss of protein absorption intensity after each cleaning step. Our effective cleaning of explanted Prolene meshes and subsequent analyses showed that they did not degrade in vivo, confirming the in vivo stability of properly formulated polypropylene. Instead, the cracked layer that some researchers have identified as degraded Prolene is an adsorbed protein–formaldehyde coating, resulting from the well-established formalin–protein fixation process, which occurs immediately upon placing an explant in formalin.
First Metatarsal Head and Medial Eminence Widths with and Without Hallux Valgus.

Background: Resection of the medial eminence in hallux valgus surgery is common. True hypertrophy of the medial eminence in hallux valgus is debated. No studies have compared metatarsal head width in patients with hallux valgus and control patients. Methods: We reviewed 43 radiographs with hallux valgus and 27 without hallux valgus. We measured medial eminence width, first metatarsal head width, and first metatarsal shaft width in patients with and without radiographic hallux valgus. Results: Medial eminence width was 1.12 mm larger in patients with hallux valgus (P < .0001). Metatarsal head width was 2.81 mm larger in patients with hallux valgus (P < .001). Metatarsal shaft width showed no significant difference (P = .63). Conclusions: Metatarsal head width and medial eminence width are significantly larger on anteroposterior weightbearing radiographs in patients with hallux valgus. However, frontal plane rotation of the first metatarsal likely accounts for this difference.
Direct measurement of resolution in volumetric imaging systems

The resolution of 2D imaging systems is frequently described by experimental estimates of the point, line, or edge spread function. It is shown that a response function across the normal to a boundary between two homogeneous volumes can provide a measure of resolution. The set of surface boundary voxels is determined by applying a simple threshold. The normal distance of every voxel to the surface is computed and an accumulator bin is incremented by the voxel's gray level. This results in an aggregate surface response function, which is related to 3D point, line, and plane spread functions. This method can be applied to general boundary interfaces where precise surface normals are known, such as those on a sphere or plane. Results of applying this method to volumetric cone beam X-ray CT data are shown. >

Transition goals for youth with social, emotional, and behavioral problems: Parent and student knowledge

ABSTRACTTransition planning is a mandated component of individualized education plans (IEPs) designed to ensure successful transition to adult life for students with disabilities. Students with social, emotional, and behavioral (SEB) needs experience poor post-school outcomes, suggesting a need for more effective transition planning. This study evaluated student and parent knowledge of employment and training goals in IEPs and the match between goals and student future planning. Ninety-three high school students and parents reported their IEP participation and knowledge of goals and responses were compared to goals in their IEPs. Results indicated that students and parents had limited knowledge of goals and a low match between the goals and student's future plans. Transition goals were frequently broad in relation to student specific future plans, potentially indicating a lack of student input and consideration of student interests and preferences in transition planning. Recommendations are discussed to h...
Optimized detection of particulates from liquid samples in the aerosol phase: Focus on black carbon

ABSTRACTOperational parameters for a single particle soot photometer (SP2) and a CETAC Marin-5 nebulizer were optimized for detection of particulates aerosolized from liquid samples. The sensitivity of nebulization efficiency on nebulizer input gas pressure, liquid sample flow rate, and alcohol doping of the sample were explored. The nebulization efficiency of the Marin-5 was found to be roughly independent of applied gas pressure once above a minimum pressure. The nebulization efficiency changed by ∼50% for an order of magnitude change in liquid sample flow. Doping the sample with isopropyl alcohol at a 1:1 ratio results in a ∼50% relative increase in nebulization efficiency over a broad range of liquid flows. These results should apply to all particulate materials in the size range studied. SP2 operational parameters including sheath and sample flow were explored to optimize detection of refractory black carbon (rBC) specifically via coupling to the nebulizer. The SP2 tested samples up to 5 cc s−1 with ...
Morbidity and Mortality Associated With Medications Used in the Treatment of Depression: An Analysis of Cases Reported to U.S. Poison Control Centers, 2000–2014

Objective:The authors sought to determine the relative morbidity and mortality associated with drugs used to treat depression and to examine specific clinical effects associated with serious outcomes.Method:The National Poison Data System, which receives exposure reports from regional poison centers serving the United States, Puerto Rico, and the District of Columbia, was queried for single drug exposures in individuals 12 years and older during the period 2000–2014. Medications included were antidepressants, atypical antipsychotics, anticonvulsants, lithium, and other medications used in the treatment of depression. The main outcomes were the morbidity index (the number of serious outcomes per 1,000 exposures) and the mortality index (the number of fatal outcomes per 10,000 exposures).Results:During this 15-year period, there were 962,222 single substance exposures to the 48 medications studied. Serious outcomes rose 2.26-fold and in linear fashion over the 15 years. While tricyclic and monoamine oxidase...
Papillary fibroelastoma arising from the coumadin ridge

Cardiac papillary fibroelastomas (CPF) are rare cardiac tumors, mostly found on the valvular surfaces in the heart. These tumors are frond like in nature and are benign, intracardiac masses, rarely causing any hemodynamic disturbances. However, excision of these masses is indicated due to their propensity to embolize. We present a case report of the tumor found on the coumadin ridge, causing transient ischemic attacks in a patient. We performed complete excision of the tumor via median sternotomy on cardiopulmonary bypass support with cardiac arrest. The diagnosis was confirmed by histological examination. The patient had an uneventful postoperative course and was discharghed on postoperative day 4. She has had complete resolution of her symptoms post excision. The diagnosis of the mass was confirmed on histological examination.
Complications of Surgery After Pelvic Radiation

Radiation therapy is an important modality in the management of pelvic malignancies. Of cancer diagnosed in the year 2005, approximately 45% of male patients (prostate, rectal, bladder) and 25% of female patients (uterine, rectal, cervical, and bladder) had pelvic malignancies. More than half of all patients diagnosed with cancer receive radiation as part of their treatment.
The Human Machine

Throughout this handbook man will be considered in his relationship to the surrounding environment. He may be under water wearing a scuba outfit or living in an underwater habitat, but, because of his respiratory needs, the environment will always involve air or other respirable gas either at atmospheric pressure or under increased pressure. Man will also be considered in relationship to the various pieces of equipment he uses, works with, or lives in. In many situations he will be part of a closed loop, but always with remarkable feedback potential. The cybernetic man-machine relationship will be evident in most of the underwater work man engages in.
A comparison of multiple methods for mapping local-scale mesquite tree aboveground biomass with remotely sensed data

Abstract A local-scale mesquite tree (Prosopis glandulosa Torr.) aboveground biomass map contribute to our understanding of the spatial distribution of woody plant aboveground biomass, and carbon stocks and fluxes in rangeland ecosystems. The objective of the study was examining a methodological approach to use airborne lidar data and multispectral imagery to create very high spatial resolution local-scale mesquite tree aboveground biomass maps by comparing three statistical methods and identifying significant prediction variables. The three statistical methods were the stepwise regression, the least absolute shrinkage and selection operator (LASSO), and the random forests. These methods were applied to establish the mesquite tree aboveground biomass equations and model from the in-situ mesquite tree aboveground biomass with the lidar metrics and multispectral data. The results showed the stepwise regression and LASSO had limited adj-R2 and MSE. However, the random forests method with combined multispectral imagery and lidar data presented acceptable MSE and R2 (1.08 Mg ha−1 and 0.37). In summary, the random forests method with combined multispectral imagery and lidar data offered the most reliable and reasonable combination to generate a very high spatial resolution local-scale mesquite tree aboveground biomass map.
The EDGI new take on EDGE: EUS-directed transgastric intervention (EDGI), other than ERCP, for Roux-en-Y gastric bypass anatomy: a multicenter study.

Background and study aims Indications for accessing the duodenum, and/or excluded stomach in Roux-en-Y gastric bypass (RYGB) patients extend beyond diagnosis and treatment of pancreaticobiliary maladies. Given the high technical and clinical success of EUS-directed transgastric ERCP (EDGE) in RYGB anatomy, we adopted this transgastric (anterograde) approach to evaluate and treat luminal and extraluminal pathology in and around the excluded gut in RYGB patients. EUS-directed transgastric intervention (“EDGI”), other than ERCP, is the terminology we have chosen to describe this heterogenous group of transgastric diagnostic and/or interventional endoscopic procedures (transgastric interventions) performed via a lumen-apposing mental stent (LAMS) in select patients with RYGB. Patients and methods A multicenter (n = 4), retrospective study of RYGB patients with suspected luminal or extraluminal pathology, in or around the duodenum and/or excluded stomach, underwent EDGI using LAMS between December 2015 and January 2019. Results A total of 14 patients (78.6 % women; mean age, 55.7 + 12.4 years) underwent EDGI via LAMS. Technical and clinical success rates of EDGI were 100 %. The most common transgastric interventions were diagnostic EUS of extraluminal pathology (n = 6, 42.7 %) and endoscopic biopsy of gastroduodenal luminal abnormalities (n = 5, 35.7 %). Two moderate-severity adverse events due to LAMS maldeployment occurred during EUS-JG creation (14.3 %), and each instance was successfully rescued with a bridging stent. Conclusions A variety of gastroduodenal luminal and extraluminal disorders in RYGB patients can be effectively diagnosed and managed using EDGI via LAMS.
Chapter 25 – International Nuclear Power

Publisher Summary This chapter concentrates on the status and trends of nuclear power plants. In the decade of the 1990s, three major economic movements tended to dominate the nuclear electric industry of the world. These were privatization, globalization, and deregulation. In privatization, facilities are sold by a government to private industry to raise cash and potentially achieve better performance. Globalization involves the purchase of companies across national borders—for example, Entergy of New Orleans buying London Electricity and then selling it to Electricite de France. Consolidation into multinational companies also is popular. Deregulation opens up new options for sources of supply of electrical energy to customers. The preceding three processes tend to make the nuclear power situation abroad more fluid and complex. In Europe, it is the European Union that is the driving force behind deregulation, rather than by states as in the United States. At the social/political level, the strength of opposition to all aspects of nuclear energy has a decided influence on actions of politicians. The resultant conflict between government and industry in some countries results in stagnation or the demise of nuclear power. The need for power and the lack of fuel resources in many countries has prompted the adoption of nuclear reactors for electric power. As of the end of 2007 there were 104 operating reactors in the United States and 339 abroad. The leading countries, in decreasing order of operating nuclear power, are the United States, France, Japan, Germany, and Russia. The decline in United States reactors planned and under construction over the years is balanced by the rise in non-United States reactors.

Semantics-aware typographical choices via affective associations

With the tens of thousands of fonts that are now readily available, it is non-trivial to select the most suitable font for a given use case. Considering the impact of the choice of font on human perception of the text, there is a strong need for semantic font search and recommendation. Aiming to fulfill this need, we induce a typographical lexicon providing associations between words and fonts. For this purpose, we determine font vectors for basic and complex emotions, based on word similarities, antonymy information, and Plutchik’s Wheel of Emotions. We create a large font lexicon, named FontLex, relying on emotion associations between the words and the fonts. We evaluate our results through user studies and find that for the majority of the evaluated words, the fonts recommended by FontLex are preferred. We also further extend the dataset using synonyms of font attributes and emotion names. Finally, using CNN embeddings of the fonts, we expand our attribute score assignment to new fonts. The resulting FontLex resource provides mappings between 6.7K words and 2K fonts. Our proof of concept application demonstrates how FontLex can be invoked to obtain semantic font recommendation for poster design.
Tandem mass tagged dataset used to characterize muscle-specific proteome changes in beef during early postmortem period.

Abstract Bovine longissimus lumborum (LL) and psoas major (PM) muscles biopsy samples were collected from four carcasses (n = 4) at 45 min, 12 h, and 36 h postmortem from a commercial beef processing facility. Proteins present in the early postmortem LL and PM proteomes were identified and quantified using tandem mass tag (TMT) labelled, fractionated peptides coupled to liquid chromatography tandem mass spectrometry (LC-MS/MS). The data are supplied in this article and are related to “Tandem mass tag labeling to characterize muscle-specific proteome changes in beef during early postmortem period” by Zhai et al. [1].
Conventional Angiography in the Assessment of Recently Symptomatic Patients with Ipsilateral Carotid Stenosis.

Abstract Background and Purpose Benefits of revascularization for moderate and severe (≥50%) carotid stenosis were established based on digital subtraction angiography (DSA). We aimed to assess the discrepancy between invasive and non-invasive angiography in a consecutive, prospective cohort of patients with recent stroke and non-invasive imaging suggesting ≥50% ipsilateral carotid stenosis. Materials and Methods We reviewed prospectively-collected data for consecutive patients admitted with recent stroke/TIA and ≥50% ipsilateral carotid stenosis on non-invasive imaging over 28 months. All patients underwent DSA to confirm the degree of stenosis per NASCET criteria. All patients with Results 148 symptomatic patients with ≥50% ipsilateral carotid stenosis on CTA (82%) and MRA (18%) underwent DSA to confirm degree of stenosis. Median age was 73 years and 64% were male. DSA demonstrated Conclusion In nearly one-in-five cases with recent stroke due to ipsilateral carotid stenosis deemed to be candidates for revascularization based on CTA or MRA, DSA led to institution of medical therapy only due to insufficiently severe stenosis. In patients treated with medical therapy based on the findings of

A feasibility study of time of flight cone beam computed tomography imaging.

BACKGROUND The time of flight (TOF) cone beam computed tomography (CBCT) was recently shown to reduce the X-ray scattering effects by 95% and improve the image CNR by 110% for large volume objects. The advancements in X-ray sources like in compact Free Electron Lasers (FEL) and advancements in detector technology show potential for the TOF method to be feasible in CBCT when imaging large objects. OBJECTIVE To investigate the feasibility and efficacy of TOF CBCT in imaging smaller objects with different targets such as bones and tumors embedded inside the background. METHODS The TOF method used in this work was verified using a 24 cm phantom. Then, the GATE software was used to simulate the CBCT imaging of an 8 cm diameter cylindrical water phantom with two bone targets using a modeled 20 keV quasi-energetic FEL source and various TOF resolutions ranging from 1 to 1000 ps. An inhomogeneous breast phantom of similar size with tumor targets was also imaged using the same system setup. RESULTS The same results were obtained in the 24 cm phantom, which validated the applied CBCT simulation approach. For the case of 8 cm cylindrical phantom and bone target, a TOF resolution of 10 ps improved the image contrast-to-noise ratio (CNR) by 57% and reduced the scatter-to-primary ratio (SPR) by 8.63. For the case of breast phantom and tumor target, image CNR was enhanced by 12% and SPR was reduced by 1.35 at 5 ps temporal resolution. CONCLUSIONS This study indicates that a TOF resolution below 10 ps is required to observe notable enhancements in the image quality and scatter reduction for small objects around 8 cm in diameter. The strong scattering targets such as bone can result in substantial improvements by using TOF CBCT.
