Fibronectin fragments and their role in inflammatory arthritis

Abstract Objectives: To identify potential immunopathogenic links between fibronectin(Fn) fragmentation and the inflammatory response in chronic joint disease. Methods: Scientific papers involving studies of Fn fragments and inflammatoryprocesses important in the pathogenesis of arthritis, including chondrolysis, synoviocyte growth and adhesion, polymorphonuclear leukocyte (PMN) and monocyte function, proteolysis, and immune complex activation were reviewed. In addition, reports identifying Fn fragments in synovial fluid (SF) were assessed. Results: A series of Fn fragments have been identified in arthritic SF by severalinvestigators. Fn and fragments ranging from 30 to 200 kd are present in elevated concentrations in inflammatory SF. SF Fn fragments display reduced affinity for fibrin and collagen. The 29- and 50-kd amino terminal fragments mediate release of proteoglycan from articular cartilage by RGD-independent mechanisms. Fn fragments can induce fibroblast gene expression of metalloproteinases or can act as proteinases themselves. A 90-kd plasmin generated fragment possesses homology with streptokinase. Fragments mediate PMN chemotaxis and enhance proliferation of CD4+ lymphocytes as well as binding to the C1q component of complement and influencing the behavior of immune complexes. Conclusions: Fn fragments can be functionally and biochemically characterizedin diseased SF Modification of fragment formation and inhibition of fragment function may have potential therapeutic value in the interruption of chronic synovial inflammation.
Modern Financial Theory, Corporate Strategy and Public Policy: Three Conundrums

Modern financial theory raises difficult issues for corporate strategy and public policy. Three such issues of significance to both theory and practice are delineated. Implications for researchers and practitioners are discussed.
Gender role orientation is associated with health-related quality of life differently among African-American, Hispanic, and White youth

This study examined the association between gender role orientation (GRO) and health-related quality of life (HRQOL) in youth, and how this relationship may differ between males and females as well as among African-American, White, and Hispanic individuals. GRO has been reported to influence serious health outcomes including cancer, heart disease, mental illness, and mortality rates. However, few studies have examined the link between GRO and health outcomes for children, even though gender identity is formed in childhood. Data were examined from 4824 participants in the Healthy Passages™ project, a population-based survey of fifth-grade children in three US metropolitan areas. Children reported their own HRQOL using the PedsQL and degree of female, male, and androgynous GRO using the Children’s Sex Role Inventory. Based on structural equations analysis, male GRO was positively associated with HRQOL for all racial/ethnic groups, regardless of sex, whereas female GRO was associated with better HRQOL for Hispanic and White females and poorer HRQOL for Hispanic males. Androgynous GRO was associated with better HRQOL among Hispanic and White females, but not males nor African-Americans of either sex. Racial/ethnic differences emerged for female and androgynous, but not male, GROs. Hispanic males are the only group for which GRO (female) was associated with poorer HRQOL. Future research should find ways to help youth overcome negative effects on health from gender beliefs and behavior patterns with sensitivity to racial/ethnic membership.
A non-well-founded primitive recursive tree provably well-founded for co-r.e. sets

We construct by diagonalization a non-well-founded primitive recursive tree, which is well-founded for co-r.e. sets, provable in Σ1 0. It follows that the supremum of order-types of primitive recursive well-orderings, whose well-foundedness on co-r.e. sets is provable in Σ1 0, equals the limit of all recursive ordinals ω1 ck .

Spill structure in intense beams

Fixed target studies of small branching ratio decay processes require intense beams and smooth spills. Longitudinal structure arises through collective effects, well below the coasting beam stability threshold. These structures have been observed at the Brookhaven AGS and dependence on intensity and momentum spread measured. Measurements and amelioration techniques have been developed and will be described.
A cell-averaging chebyshev spectral method for nonlinear fredholm-hammerstein integral equations

In this paper we present a cell-averaging Chebyshev spectral method for solving Fredholm-Hammerstein integral equations of the form . The method is first applied to an equivalent integral equation of the form , where the function z is approximated by a Chebyshev polynomial, z N , of the first kind. We then seek a Chebyshev polynomial solution y N to y via and establish the uniform convergence of y N to y. Illustrative examples are included and comparison is made with the existing methods in the literature.
Channel Density Minimization by Pin Permutation

We present in this paper a linear time optimal algorithm for minimizing the density of a channel (with exits) by permuting the terminals on the two sides of the channel. This compares favorably with the previously known near-optimal algorithm presented in [6] that runs in superlinear time. Our algorithm has important applications in hierarchical layout design of intergrated circuits. We also show that the problem of minimizing wire length by permuting terminals is NP-hard in the strong sense.
GENE SELECTION USING LOGISTIC REGRESSIONS BASED ON AIC, BIC AND MDL CRITERIA

In microarray-based cancer classification, gene selection is an important issue owing to the large number of variables (gene expressions) and the small number of experimental conditions. Many gene-selection and classification methods have been proposed; however most of these treat gene selection and classification separately, and not under the same model. We propose a Bayesian approach to gene selection using the logistic regression model. The Akaike information criterion (AIC), the Bayesian information criterion (BIC) and the minimum description length (MDL) principle are used in constructing the posterior distribution of the chosen genes. The same logistic regression model is then used for cancer classification. Fast implementation issues for these methods are discussed. The proposed methods are tested on several data sets including those arising from hereditary breast cancer, small round blue-cell tumors, lymphoma, and acute leukemia. The experimental results indicate that the proposed methods show high classification accuracies on these data sets. Some robustness and sensitivity properties of the proposed methods are also discussed. Finally, mixing logistic-regression based gene selection with other classification methods and mixing logistic-regression-based classification with other gene-selection methods are considered.
Treatment-Mediated Changes in Human Immunodeficiency Virus (HIV) Type 1 RNA and CD4 Cell Counts as Predictors of Weight Growth Failure, Cognitive Decline, and Survival in HIV-Infected Children

This meta-analysis of 5 large studies of the Pediatric AIDS Clinical Trials Group was undertaken to evaluate the predictive value of antiretroviral treatment-mediated changes in 3 markers of human immunodeficiency virus (HIV) type 1 disease progression-HIV-1 RNA level, CD4 cell count, and CD4 percentage-for weight growth failure, cognitive decline, and survival in HIV-infected children. Proportional hazards models were used to assess the prognostic value of the markers at baseline and after 24 weeks of treatment, with data from 1089 children. Among children receiving nucleoside with or without nonnucleoside reverse-transcriptase inhibitors, higher immunologic and lower virologic markers at baseline and after 24 weeks were significant independent predictors of survival, whereas virologic markers were significant predictors of weight growth and cognitive failure in children >1 year old. The finding of differential age effects on pediatric-specific clinical outcomes emphasizes the need for continued investigation of treatment effects in children.
Universal asset assessment system based on excel

At the 2009 IEEE International Conference on Technologies for Homeland Security the author presented a paper entitled “Comparing Apples to Oranges” which showed the fundamental problem of ranking assets on multiple-factors. In particular, the talk showed that programs like Carver2 cannot consistently order targets. In particular, the author contends that using a spreadsheet such as Excel™ permits users to do as good a job of assessing targets as more dedicated systems. To improve the usefulness of Excel™ for target selection, the author has written a module that permits the spreadsheet to identify Condorcet cycles so that users will get a more realistic understanding of the vulnerability of their various assets. This paper describes the theoretical basis for this module and illustrates its operation. This module is available from the author.
A pilot study of the feasibility and efficacy of the Strategies to Enhance Positive Parenting (STEPP) program for single mothers of children with ADHD.

Objective: The Strategies to Enhance Positive Parenting (STEPP) program was developed to address putative factors related to poor engagement in and outcomes following traditional behavioral parent training (BPT) for single mothers of children diagnosed with ADHD. Method: Twelve single mothers of children with ADHD were enrolled in an initial investigation of the feasibility and preliminary efficacy of the 9-week STEPP program. Results: Results indicated that the STEPP program was effective in reducing problematic child behavior and improving parental stress and psychopathology at posttreatment. The STEPP program resulted in high rates of treatment attendance and completion and consumer satisfaction with the program. However, results also indicated that the STEPP program did not improve childrens' overall psychosocial impairment and resulted in small effect size findings across measures. Conclusion: The results of the pilot study are encouraging but indicate a need to improve the potency and delivery of ce...
Addressing Diversity in STEM Education: Authenticity and Integration

This talk will reflect on the challenges of designing educational opportunities that broaden diversity in the ranks of future scientists and engineers. The speaker, who is Education Director at the California Nanosystems Institute (CNSI) at the University of California, Santa Barbara, will report on the design and evaluation of a program that integrates academic, career and social components to engage a community of undergraduates, graduate mentors and research faculty at UCSB. The program builds on key practices such as academic mentorship, community networking and early undergraduate research. Evaluation of this program, Expanding Pathways to Science, Engineering and Mathematics (EPSEM) indicates that it has been successful in recruiting and retaining students from under-represented (URM) groups into science, technology, engineering and math disciplines (STEM disciplines).
It's not easy being green: understanding home computer power management

Although domestic computer use is increasing, most efforts to reduce energy use through improved power management have focused on computers in the workplace. We studied 20 households to understand how people use power management strategies on their home computers. We saw computers in the home, particularly desktop computers, are left on much more than they are actively used suggesting opportunities for economic and energy savings. However, for most of our participants, the economic incentives were too minor to motivate them to turn off devices when not in use, especially given other frustrations such as long boot up times. We suggest research directions for home computer power management that could help users be more green without having to dramatically change their home computing habits.
Recent Advances in Cytokine Therapy in Leprosy

Lepromatous leprosy is characterized by a selective anergy to Mycobacterium leprae and its antigens. The inadequate immune response and the resulting reduced interferon-γ (IFN-γ) production lead to a lack of macrophage activation and unrestricted bacterial growth. Purified protein derivative of tuberculin induced a normal local immune response in many lepromatous leprosy patients. Interleukin-2 induced an accelerated equivalent of an antigen response in the skin. In both, monocytes and T cells were recruited, and changes in keratinocytes, including expression of major histocompatibility complex class II antigens, were induced
Removal of Respiratory Influences From Heart Rate Variability in Stress Monitoring

This paper addresses a major weakness of traditional heart-rate-variability (HRV) analysis for the purpose of monitoring stress: sensitivity to respiratory influences. To address this issue, a linear system-identification model of the cardiorespiratory system using commercial heart rate monitors and respiratory sensors was constructed. Subtraction of respiratory driven fluctuations in heart rate leads to a residual signal where the effects of mental stress become more salient. We experimentally validated the effectiveness of this method on a binary discrimination problem with two conditions: mental stress of subjects performing cognitive tasks and a relaxation condition. In the process, we also propose a normalization method that can be used to compensate for ventilation differences between paced and spontaneous breathing. Our results suggest that, by separating respiration influences, the residual HRV has more discrimination power than traditional HRV analysis for the purpose of monitoring mental stress/load.
The wrong white crystals: not salt but sugar as aetiological in hypertension and cardiometabolic disease

Cardiovascular disease is the leading cause of premature mortality in the developed world, and hypertension is its most important risk factor. Controlling hypertension is a major focus of public health initiatives, and dietary approaches have historically focused on sodium. While the potential benefits of sodium-reduction strategies are debatable, one fact about which there is little debate is that the predominant sources of sodium in the diet are industrially processed foods. Processed foods also happen to be generally high in added sugars, the consumption of which might be more strongly and directly associated with hypertension and cardiometabolic risk. Evidence from epidemiological studies and experimental trials in animals and humans suggests that added sugars, particularly fructose, may increase blood pressure and blood pressure variability, increase heart rate and myocardial oxygen demand, and contribute to inflammation, insulin resistance and broader metabolic dysfunction. Thus, while there is no argument that recommendations to reduce consumption of processed foods are highly appropriate and advisable, the arguments in this review are that the benefits of such recommendations might have less to do with sodium—minimally related to blood pressure and perhaps even inversely related to cardiovascular risk—and more to do with highly-refined carbohydrates. It is time for guideline committees to shift focus away from salt and focus greater attention to the likely more-consequential food additive: sugar. A reduction in the intake of added sugars, particularly fructose, and specifically in the quantities and context of industrially-manufactured consumables, would help not only curb hypertension rates, but might also help address broader problems related to cardiometabolic disease.
‘Our conception of non-partisanship means a partisan non-partisanship’: the search for political identity in the American Federation of Labor, 1947–1955

This article reconsiders the evolution of political action in the American Federation of Labor between 1947 and 1955 by examining the American Federation of Labor's (AFL's) first overtly political arm, Labor's League for Political Education. It argues that the key dynamic shaping labor's political activities in this crucial period was the tension between a tradition of non-partisanship and the imperatives of an evolving political landscape that made meaningful neutrality impossible. By 1952, decentralization, local autonomy, and non-partisanship had given way to a political identity marked by centralization, national coordination, and partisan alliances.
Taxing and Regulating College and University Endowment Income: The Literature's Perspective

College and university endowments have reported outstanding investment returns in recent years. While annual investment returns have averaged around 15.2%, colleges and universities have only been spending about 4.6% of their endowment assets each year. This has drawn the attention of the Senate Committee on Finance, which recently held a hearing regarding the accumulation of endowment income at colleges and universities and debated whether endowments should be taxed or regulated (for example, by the use of the minimum distribution requirement that applies to private foundations). This Article marshals and fuses the existing literature on endowments, the rationales for tax exemptions, the justifications for the unrelated business income tax, and the reasoning behind the private foundation minimum distribution requirements to determine whether a tax on endowment income or a minimum distribution requirement would be consistent with our current understanding of how colleges and universities should be taxed. The Article concludes that the existing literature would not justify taxing or regulating endowment accumulation and that any attempt to tax or regulate endowments should only be undertaken in light of a fundamental re-imagining of our tax exempt system.
Diagnosis of systemic candidiasis in smears of venous blood stained with Wright's stain.

A 63-year-old man with systemic candidiasis following multiple recent surgical procedures for correction of intestinal obstruction and an indwelling central venous pressure (CVP) catheter was first found to have Candida albicans by examination of a smear of venous blood stained with Wright’s stain. Descriptions of the organism and suggestions for the identification of similar cases are presented. This case report emphasizes that systemic candidiasis may first be detected by examination of a blood smear.
Movement constraints on interpersonal coordination and communication

The present study investigated how constraining movement affects interpersonal coordination and joint cognitive performance. Pairs of participants worked cooperatively to solve picture-puzzle tasks in which they conversed to identify differences between pictures in 3 degree-of-constraint conditions: both participants were free to move their hands (free-free; FF); both participants' hands were restrained (restrained-restrained; RR); and the hands of 1 participant were free while the hands of the other participant were restrained (free-restrained; FR). Eye tracking data were collected, and movement was measured at the waist, hand, and head. Data were analyzed using Cross-Recurrence Quantification Analysis (CRQ). Postural sway coordination, gaze coordination, and task performance were predicted to be highest in FF, followed by RR, and then by FR. Results showed the asymmetric FR condition generally exhibited lesser degrees of coordination than the symmetric Conditions FF and RR, and that the patterning of coordination in the symmetric conditions varied across the measured body segments. These results demonstrate that movement restraints affect not only interpersonal postural coordination, but also joint attention. Additionally, significant positive relationships were found between task performance and total amount of anterior-posterior movement measured at the head, hand and waist; number of utterances; and number of differences pairs found in the puzzles. These findings indicate a relationship between movement and task performance consistent with the hypotheses that both interpersonal coordination and cognitive performance are sensitive to local action constraints.
Upper and Lower Bound Estimation of Runway Throughput in the Presence of Uncertainty

Upper and lower bound estimation for runway capacity are presented in the presence of various uncertainties for a single runway airport. Currently, arrivals touch down on runways are either assumed to be predetermined and controllable, or fully controllable. Also, uncertainties in aircraft trajectories, whether they are on the ground or in the air, are dealt with reactively as opposed to proactively. As one of the solutions to these problems stated, a two stage stochastic model can be formulated to determine feasible and optimal schedule for both arrival and departure at runway, taxiway and ramp. In order to show the necessity of developing the stochastic model for optimizing arrival and departure schedule in feasible bound, several study cases are introduced along with the results using Monte-Carlo simulation for a single runway airport in this paper. In this study, both arrival and departure capacity are calculated for various service rates of runway for 1) predetermined/uncontrollable and 2) fully controllable arrival stream. Also, the case with and without uncertainty from arrival-departure interaction and taxi time distribution are included in Monte-Carlo simulation to study the effect of uncertainty. Although both arrival and departure capacity decrease with number of uncertainty added in the simulation, the average departure capacity increases by modifying the arrival stream from an non-integer to an integer problem while maintaining similar average arrival capacity, especially at busy hour of airport. This result shows the benefit of modifying the arrival stream as an integer problem for optimizing the runway resource as well as overall airport operation efficiency. Based on numerical results, predetermined/uncontrollable and controllable arrival stream are planned to be used for lower and upper bound estimation, respectively, in the presence of various uncertainty in two stage stochastic model in the future.

Diagenesis and porosity evolution of sandstones in Xujiahe Formation,Yuanba area

The sandstones in the Triassic Xujiahe Formation in Yuanba area are typical low-porosity and lowpermeability reservoirs. The diagenesis and porosity evolution of sandstones as well as their influences on reservoir physical properties were studied by means of ordinary and casting thin section microscopic identification,SEM and X-ray diffraction. The main diagenetic effects included compaction /pressolution,cementation,replacement,corrosion and cracking,among which the compaction /pressolution,siliceous and carbonate cementation effects greatly reduced native sandstone porosities and destructed sandstone reservoirs,while the chlorite rim cementation,corrosion and fracturing effects protected and improved reservoirs. At present,the sandstones in the Xujiahe Formation in Yuanba area have entered the middle diagenesis stage A,and partially in the middle diagenesis stage B. Most of the reservoir's primary porosities have been destroyed after severe diagenetic evolution,and the main pore types are secondary pores and associated cracks.
Electron Tomography of Paracrystalline 2D Arrays

Paracrystalline arrays possess specific types of disorder that reduce the structural information as well as resolution when spatially averaged over repeating motifs. Electron tomography combined with motif classification and averaging can solve the heterogeneity problem and provide information on the structural elements that give rise to the disorder. This chapter describes procedures that would be used in a typical tomography application to identify and characterize a paracrystalline specimen. Particular emphasis is given to actively contracting insect flight muscle, a specimen with particularly difficult to characterize structural heterogeneity and 2D paracrystalline arrays of myosin-V, from which a particularly high resolution motif average was obtained. All aspects of the study are described including data collection, merging of micrographs to produce the tomogram, alignment to an invariant structural element, classification and averaging of heterogeneous structures, and reassembly of focused class averages into high signal-to-noise ratio representations of the original raw repeats. Particular emphasis is placed on limitations of the various processes to produce the final class averages.
Processor performance modeling using regression method

Estimating and modeling processor performance for a given workload is important for many processor architects and benchmark developers. Developing a performance estimation method using analytical approach to estimate processor performance reduces the burden of relying on simulation approach which requires a simulator and trace sampling for a given benchmark. In this paper, we present a processor performance model using regression approach rather than simulated approach. The baseline for the model is implemented using SPEC CPU2006 benchmark with Nehalem processor. The model enables the changing of different processor micro-architecture parameters such as number of cores, processor core frequency and memory DIMM speed to estimate the CPU2006 performance for a different processor of similar architecture. The model is verified to estimate performance with 10% error margin between estimated and measured baseline.

On the skill of seasonal sea surface temperature forecasts in the California Current System and its connection to ENSO variability

The California Current System (CCS) is a biologically productive Eastern Boundary Upwelling System that experiences considerable environmental variability on seasonal and interannual timescales. Given that this variability drives changes in ecologically and economically important living marine resources, predictive skill for regional oceanographic conditions is highly desirable. Here, we assess the skill of seasonal sea surface temperature (SST) forecasts in the CCS using output from Global Climate Forecast Systems in the North American Multi-Model Ensemble (NMME), and describe mechanisms that underlie SST predictability. A simple persistence forecast provides considerable skill for lead times up to ~4 months, while skill above persistence is mostly confined to forecasts of late winter/spring and derives primarily from predictable evolution of ENSO-related variability. Specifically, anomalously weak (strong) equatorward winds are skillfully forecast during El Nino (La Nina) events, and drive negative (positive) upwelling anomalies and consequently warm (cold) temperature anomalies. This mechanism prevails during moderate to strong ENSO events, while years of ENSO-neutral conditions are not associated with significant forecast skill in the wind or significant skill above persistence in SST. We find also a strong latitudinal gradient in predictability within the CCS; SST forecast skill is highest off the Washington/Oregon coast and lowest off southern California, consistent with variable wind forcing being the dominant driver of SST predictability. These findings have direct implications for regional downscaling of seasonal forecasts and for short-term management of living marine resources.
Brief Thoughts on Zen and Behavior Therapy

Brief Thoughts on Zen and Behavior Therapy is presented by one of the leading researchers and clinicians in behavior therapy today: Marsha Linehan, creator of Dialectical Behavior Therapy. In it, Dr. Linehan describes her journey in becoming a behavior therapist and a Zen Roshi, elaborating on the similarities and differences between these two professions and identities. Dr. Linehan also highlights cultural influences on our perceptions of religion, including her analysis of the ways in which Buddhism is not necessarily mutually exclusive with other prominent world religions today; Dr. Linehan herself was raised in Catholicism. From her perspective, Zen is in line with mystical traditions, whereas behavior therapy is in line with science. The two coexist nicely when one remembers what many astronomers have posited: scientists who the study the universe ultimately become mystics themselves.
Electrocardiographic-Guided Technique for Placement of Ventriculoatrial Shunts: A Valid and Cost-Effective Technical Simplification.

Background Ventriculoatrial (VA) shunt is a routine technique for the treatment of hydrocephalus. The correct position at the superior vena cava–right atrium junction is generally assessed by radiography. We present the first experience of an alternative, nonradiographic technique to assess the distal end of the VA shunts through an electrocardiographic (EKG) method. The technique has developed from the large experience of central venous catheters (CVC) worldwide; the EKG-guided method is a common and validated alternative to standard radiologic control of the location of the tip of any CVC. Methods Five consecutive patients underwent VA shunt with venous catheter positioned with the EKG-guided technique. The position of the catheter tip was verified by standard chest radiography. Results Four men and 1 woman (mean age, 45.4 years) underwent VA shunt for hydrocephalus with the EKG-guided technique. The side of internal jugular vein puncture was the right side in 4 cases and the left side in 1 case. As confirmed by radiography, all VA shunt tips were located within the correct range. There was no radiologic evidence of procedure-related complication or catheters that had to be replaced. Conclusions The EKG-guided technique for VA shunts is as accurate as fluoroscopy, but simpler, more readily available, less expensive, safer, and more cost effective. It reduces the need of radiography and radiologic exposition for both patients and operators. The EKG method may be a valid and cost-effective alternative to standard radiologic control in VA shunts, as for any central venous access device, and could become the preferential method for confirming tip position during VA shunt surgery.
Animating the Image: Patch Work and Video Interactivity

This chapter charts the relation between the elliptical visual style of Tsukamoto Shinya’s early films, in particular Tetsuo: the Iron Man, and the economic shortcuts of low-budget animation, which compress spatial and temporal coordinates in the frame instead of aiming for seamless continuity. Lee highlights how Tetsuo transforms these anime techniques into a live-action display of discontinuity that harnesses the interval between frames to connect cinema to then-new video and interactive technologies. It points to the importance of this strategy for invigorating the flagging industry in the late 1980s and early 1990s: by mobilizing the aesthetics of popular media to generate a low-budget, sensorial style, Tetsuo confirmed the viability, both domestically and internationally, of a visceral film practice that privileged sensation over narrative.
He can read your mind: Perceptions of a character-guessing robot

After playing a five to seven minute character guessing game with a Nao robot, children answered questions about their perceptions of the robot's abilities. Responses from interactions with 30 children, ages eight to twelve, showed that when the robot made an attempt at guessing the participant's character, rather than being stumped and unable to guess, the robot was more likely to be perceived as being able to understand the participant's feelings and able to provide advice. Regardless of their game experience, boys were more likely than girls to feel they could have discussions with the robot about things they could not talk to other people about. This article provides details associated with the implementation of a game used to guess a character the children selected; a twelve question verbally-administered survey that examined their perceptions of the robot; quantitative and qualitative results from the study; and a discussion of the implications, limitations, and future directions of this research.
X-ray image guidance workflow development for in-vivo aneurysm treatment using a new retrievable asymmetric flow diverter (RAFD)

The vascular procedures during in–vivo aneurysms treatment with the Retrievable Asymmetric Flow Diverter (RAFD) prototype, require accurate x-ray image guidance and flow diversion assessment using angiography. The new device is made of a high porosity scaffold which supports a low-porosity patch used to divert the blood flow from the aneurysm. Two platinum markers have been added to allow stent placement in the longitudinal and azimuthal direction with regard to the aneurysm ostium. The retrievability of the device allows for multiple re-deployments until the placement is optimal. Eleven elastase aneurysms were created and treated with the new device. Placement was done using high definition x-ray fluoroscopy and optimal blood flow diversion was verified using angiography. Once the flow diversion was confirmed, the devices were deployed using electrolytic detachment. Angiograms pre- and post-stent placement were analyzed using parametric imaging based on dye dilution curves of injected contrast. Average values of the area under the curve (AUC), Meant Transit Time (MTT) and Peak Value (PV) for the aneurysms were measured and normalized to the values recorded in the main vessel. Fluoroscopy time for the device deployment was 15.30±5.30 minutes. Angiographic analysis indicated that average normalized values for: MTT increased 227%, AUC decreased 51% times while PV decreased 30%. In conclusion, the device was successfully deployed in eleven rabbits. Based on angiogram analysis, significant flow diversion has been observed. Overall this report demonstrates that the imaging workflow we developed for the new device placement was implemented successfully.
Off to infinity in finite time

W ithout collisions could the Newtonian n-body problem of point masses eject a particle to infinity in finite time? This intriguing century-old concern, which has motivated several interesting and deep mathematical conclusions, was recently resolved by Xia ([X1, 2]) in his Ph.D. dissertation; he proved that three-dimensional examples exist for all n ≥ 5. Later, Gerver [G] asserted that a similar behavior occurs with the planar 3n body problem but with an unknown and very large n value. Even the suggestion that our familiar Newtonian inverse square force law might allow such a counter-intuitive behavior is so surprising that it is reasonable to wonder how such an esotericsounding question was first raised. As we show in this brief survey, Xia’s result resolves a natural, fundamental problem raised by Poincare and Painleve about a century ago. The issue is to characterize the nature of “singularities” of n-body systems. Here, a singularity is a “time” value t = t∗ where analytic continuation of the solution fails. So, what constitutes a singularity? Let mj, rj be, respectively, the mass and position vector of the jth particle, and let rij = ‖ri − rj‖. From the equations of motion
Clinical Manifestations of Hypoparathyroidism

Most symptoms and clinical signs of hypoparathyroidism result from the associated hypocalcemia; thus, paresthesia, tetany, seizures, and hypocalcemic cardiomyopathy are classic presentations of the disease. These symptoms, however, may vary depending on several factors including the severity and rapidity of the development of hypocalcemia. In addition, there are large inter-individual differences in the threshold of serum calcium, below which symptoms manifest. Other features, most notably intracranial calcification, may not be directly related to low plasma calcium levels, but possibly to hyperphosphatemia or a high serum calcium–phosphate product. The rarity of the disease has made large and systematic natural history studies difficult.
Bounds for Matrix Coefficients and Arithmetic Applications

We explain an important result of Hee Oh [20] on bounding matrix coefficients of semi-simple groups and survey some applications.
Thermodynamics and Dynamics in the Vertical

Much can be learned about the local weather—the height at which clouds will form, the likelihood of thunderstorms or of an air-pollution episode— by analyzing the thermodynamics and dynamics of parcels of air moving up and down through the atmosphere. Such parcels move through an atmospheric environment in which the vertical forces, the weight of the air and the upward decrease in pressure, are in balance. This is termed hydrostatic balance. The first model in this chapter uses this balance to find the pressure and density of the atmosphere given the pressure at the ground and a vertical temperature profile. This model then becomes a component of the subsequent models, which include first the thermodynamics, dry and moist, and then the dynamics, of air moving vertically.
Recent Advances in Acute Lymphoblastic Leukemia

We have witnessed remarkable gains in the biological understanding and treatment of acute lymphoblastic leukemia (ALL) over the past decade.
Justice Beyond Dispute

This is a book review of Ethan Katsh and Orna Rabinovich-Einy’s Digital Justice: Technology and the Internet of Disputes. According to Katsh and Rabinovich-Einy, "disputes... are the collateral damage of innovation." While that may be true, it is also true that we do not all share the same risk of becoming collateral damage and that we do not share equally in the spoils of innovation. While the online dispute resolution approach championed in Digital Justice holds great promise for improving procedural justice in commercial and institutional transactions, its idealization of technology makes it unsuitable for resolving anti-social interactions facilitated by social media. The internet is currently overrun with violence, threats, revenge porn, propaganda, and conspiracy theories. These conflicts, which disproportionately burden women and racial, religious, and sexual minorities, are facilitated by powerful tech corporations with little incentive to pour their considerable resources into eliminating them. Resolving or preventing these disputes requires the rejection of technological determinism and engagement with the reality of consent, power, labor, and compromised intermediaries.

Vanishing racial disparities in drowning in Florida

Objectives To examine the change in the racial disparity in drowning in Florida from 1970 to 2015 and to analyse the contextual factors associated with white, black and Hispanic drowning rates in Florida from 2007 to 2015. Methods Our outcome variable is county-level annual drowning rates by race, ethnicity, sex and age group. We computed county-level contextual data, including emergency weather events, temperature, extreme weather, number of pools, quality of pools, coastline, swimming participation rates and prominent black competitive swim teams. Results Between 1970 and 1990, the disparity in drowning rates between white and black males in Florida decreased dramatically. By 2005, the overall age-adjusted drowning rates converged. This convergence was most striking for those aged 10–34 and 35–64. While the gap has declined dramatically, there remains a racial disparity in drownings among those aged 10–34. Conclusions Overall, racial disparities in drowning have disappeared in Florida. However, some disparities remain. There is a persistent disparity in drownings among those aged 10–34.

Maritime Security and Governance of the South Atlantic: The Nigerian Perspective

This chapter deals with maritime security and governance of the South Atlantic, principally from Nigeria’s perspective. The Gulf of Guinea in particular and the wider South Atlantic in general, have recently become a hotbed of piracy and other transnational crimes that impede legitimate maritime activities. Given the nature of transnational crimes and the jurisdictional and organizational complexity for setting up a maritime security operation, the growing range of threats and challenges tend to exceed the capacity of individual states to address them. Therefore, the chapter reassesses the levels of collaboration among the regional stakeholders and the prospects for setting up maritime security governance to tackle the potential threat and challenges, within the overarching framework of ‘South–South cooperation’. It also delineates Nigeria’s continued interest and commitment to promoting bilateral and multilateral initiatives in maritime security cooperation and governance with the goal of enhancing the safety and security of navigation, marine environmental protection as well as ensuring peaceful and cooperative maritime operations in the South Atlantic. Some policy recommendations are presented to broaden its engagements as a way to maintain peaceful stability and maritime security in the South Atlantic.
Environmentally-Controlled Near Infrared Spectroscopic Imaging of Bone Water.

We have designed an environmentally-controlled chamber for near infrared spectroscopic imaging (NIRSI) to monitor changes in cortical bone water content, an emerging biomarker related to bone quality assessment. The chamber is required to ensure repeatable spectroscopic measurements of tissues without the influence of atmospheric moisture. A calibration curve to predict gravimetric water content from human cadaveric cortical bone was created using NIRSI data obtained at six different lyophilization time points. Partial least squares (PLS) models successfully predicted bone water content that ranged from 0–10% (R = 0.96, p < 0.05, root mean square error of prediction (RMSEP) = 7.39%), as well as in the physiologic range of 4–10% of wet tissue weight (R = 0.87, p < 0.05, RMSEP = 14.5%). Similar results were obtained with univariate and bivariate regression models for prediction of water in the 0–10% range. Further, we identified two new NIR bone absorbances, at 6560 cm−1 and 6688 cm−1, associated with water and collagen respectively. Such data will be useful in pre-clinical studies that investigate changes in bone quality with disease, aging and with therapeutic use.
Re)orienting Food Activism toward Social Justice

First paragraph: A fitting place to begin a discussion about Joshua Sbicca’s new book, Food Justice Now!, is with a story he shares near the middle of the book, where readers are introduced to a progressive farm situated along the U.S.-Mexico border. Wild Willow offers education for new organic farmers, provides healthy food to local consumers, hosts community gatherings, and practices non-wage exchange for labor—approaches considerably more sustainable and community-oriented than those typically used in our current food system. The farm stops short, however, of inserting itself into any kind of movement to support the rights of those migrant workers who perilously navigate the border on which the farm sits or to advocate for humane immigration reform. In so doing (and in not so doing), Wild Willow provides alternatives for local growers and consumers, but it does not confront the systems that dictate and limit the range of what those alternatives can look like. As such, the farm and the border it is situated upon are a powerful metaphor for this book’s message. While most food-based activism does not take place in the literal face of racialized, economic, and political borders, it always does so in a figurative sense. Food activism ignores this to the detriment of social justice. So, what does it take to cross these boundaries, and why aren’t more food activists doing so? What does it look like when they do, and what has this looked like historically? A central purpose of this book is to answer these questions. In the process, it offers a constructive and hopeful challenge to movements narrowly focused on issues such as health or the environment to aim higher at social justice. . . .

Intraoperative use of low-profile alternating pressure mattress for prevention of hospital acquired pressure injury

Abstract Background Facility acquired pressure injury is a problem in all care settings. Further work is necessary to better understand and intervene in specific scenarios. The operating room has not been well studied with respect to pressure injury prevention. Our purpose was to study the efficacy of a low profile alternating pressure (AP) overlay to prevent operating room associated pressure injuries. Methods This was a prospective case control study conducted in the operating room and critical care unit of an urban quaternary care hospital in the United States. Neurosurgery patients undergoing surgery for 2 hours or longer in the supine position were included in the study and assigned to receive the AP overlay in the operating room and in the Neurosurgical Intensive Care Unit (NICU) or standard treatment (control). The patients were then followed daily until discharge. Standard protocols for pressure injury prevention were maintained. Demographic data, details of the operation, pressure injury risk factors and presence of hospital acquired pressure injuries (HAPI) were recorded. The primary outcome of interest was the incidence of HAPI in the AP group compared to the control group. Results 212 patients were enrolled into the study. 104 received the AP system whereas 108 did not. The average length of stay in the NICU for the AP group was 2.2+/− 1.6 days and 2.4 +/−0.5 days for the control group (p =0.078). The average OR case length was 4.5+/− 0.8 hours for the AP group and 3.9+/−1.2 hours for the controls (p = 0.014). In the AP group, 1 patient out of 104 (0.96%) developed a pressure injury whereas 7 patients out of 108 (6.48%) developed a pressure injury in the control group (p =0.014). There were no adverse events or unintended consequences resulting from use of the AP overlays in the operating room or NICU Conclusions Low Profile Alternating Pressure mats are a safe and effective way to prevent hospital acquired pressure injuries and should be considered in patients undergoing complex procedures with increased operative time.
