Synthesis and Characterization of Ruthenium(II) Hydrido and Hydroxo Complexes Bearing the 2,6-Bis(di-tert-butylphosphinomethyl)pyridine Ligand

The reaction of [Ru(CO)2Cl2]n with 2,6-bis(di-tert-butylphosphinomethyl)pyridine) (PNP) and then anion exchange yields [Ru(PNP)(CO)2Cl]PF6 (1). Reaction of 1 with AgBF4, in acetone, followed by acetonitrile and then anion exchange gave [Ru(PNP)(CO)2(CH3CN)](PF6)2 (2); reaction of 2 with water gave [Ru(PNP)(CO)2OH]PF6 (3), whereas reaction of 2 with aqueous KOH led to [Ru(PNP)(CO)(CH3CN)H]PF6 (4). Complexes 3 and 4 have been structurally characterized.
Acoustic emission source identification using longwaveguide sensors

Abstract Acoustic emission from flaw growth and other sources is obtained by loading a medium-sized steel pressure vessel. Waveforms from the growth of three flaws are distinguishable on the basis of the characteristic impact response of the waveguide and the source mechanism. Evidence is presented that, although brittle fracture may be the fundamental process occurring in both flaw growth and oxide rupture, the manner in which these processes occur allows identification of the source.
Tectonic implications of mid-Tertiary dikes in west-central New Mexico

The N30°–35°W trend of three long basaltic andesite dikes in west-central New Mexico indicates a least principal horizontal stress direction of N55°–60°E at the time the dikes were emplaced 28 m.y. ago. This stress direction agrees with recently proposed tectonic models for the region, suggesting that northeast-southwest extension was pervasive over both the early Basin and Range and Colorado Plateau provinces and the southern Rocky Mountains at this time.
Complexes of Hydrogen Peroxide with Dioxoactinide(VI) Species in Aqueous Carbonate and Bicarbonate Media. Formation of An(VI)–H2O2 Complexes

The spectra for 1:1 complexes formed between triscarbonatouranium(VI) + H2O2 and triscarbanatoneptunium(VI) + H2O2 are presented. The respective rates of formation (25°C, 0.05 M NA2CO3) are 565 ± 41 M−1 s−1 and (2.19 ± .01) X 103 M−1 s−1. The corresponding activation parameters are ΔH* = 67.8 ± 3.2 kJ/m, 43.6 ± 2.0 kJ/m, ΔS* = 30 ± 11 J/m °K and −36 ± 7 J/m °K, respectively. The U(VI) complex appears to be stable over a period of months while the Np(VI) complex is formed as a transient species that disappears via a complex process.
Microstructure and Mineral Chemistry of Synroc‐D

Synroc-D is a polyphase nuclear waste ceramic optimally consisting of zirconolite, perovskite, an ulvospinel-rich solid solution, a hercynitic spinel solid solution, and nepheline. A continuous intergranular glass phase is also present, which may aid in densification, but decreases the waste form's durability in aqueous environments, as does the presence of nepheline. The major radionuclides are distributed in the following manner: (1) Uranium is immobilized in zirconolite and perovskite, (2) the lanthanides and strontium are immobilized in perovskite, (3) cesium is distributed between nepheline and glass. The partitioning of tetravalent uranium and trivalent actinides may prove useful as surrogates for tetravalent and trivalent actinides, respectively. The spinels are free of radionuclides and provide a degree of microencapsulation for the radio-nuclide-bearing phases. Values of mineral-mineral partition coefficients are largely dependent on powder preparation; the choice of zirconia reagent is of particular importance.
A systematic approach for supply chain improvement using design structure matrix

Supply chain is a complex system that involves many system elements from various functional areas. Performance of a supply chain heavily depends on the effectiveness of communication and coordination among these system elements and functional areas. However, a large and complex supply chain usually makes it difficult to coordinate and thus degrades its performance. This paper focuses on the development of a systematic approach with the following objectives: (1) to identify and quantify the interactions among the system elements in a supply chain; (2) to decompose the large interdependent group of system elements into smaller and manageable sub-groups; and thus (3) to improve the structure of the supply chain system. A supply chain system is first decomposed into subsystems and system elements from which the interactions (i.e., independent, dependent and interdependent relationships) are studied and documented by design structure matrix (DSM). Next, the interaction strengths among the related system elements are quantified. Cluster analysis is used to decompose the large interdependent group into smaller ones in order to provide a better supply chain system structure. The effectiveness of this systematic approach is demonstrated by an illustrative example. The result shows that it is able to improve the system structure of a supply chain that will be useful for the supply chain reengineering.

The Challenges, Influences, and Experiences of Slavic Immigrant Education in the U.S

In the today’s diverse society, it is necessary for educators to understand and be familiar with the values, ideas, attitudes, beliefs, experiences, and social and cultural contexts that have shaped the lives of their students in order to provide optimal learning opportunities. This article is a synthesis of research regarding the challenges, influences, and experiences of Slavic students in the United States at the primary and secondary school levels. Due to the lack of research concerning Slavic students in the United States, this article has examined literature surrounding the experiences of immigrant students, English Learners (ELs), and Slavic students in an attempt to find common ground.
Zero-Parameter Problems

In the second chapter I derived general formulas that enable one to write phase and log-amplitude variances, power spectral densities, and Strehl ratios as integrals. Different cases differ only in the appearance of different filter functions. In the last chapter explicit filter functions were derived for a variety of problems. With the use of these filter functions, integrands contain the following functions: sin (x), cos (x), sin2 (x), cos2 (x), J ν (x), J ν (x) J μ (x), J ν 2 (x), exp (x), (1 + x) − p, (x − 1)−p U(x− 1), and K (x).
On Modern Clause-Learning Satisfiability Solvers

In this paper, we present a perspective on modern clause-learning SAT solvers that highlights the roles of, and the interactions between, decision making and clause learning in these solvers. We discuss two limitations of these solvers from this perspective and discuss techniques for dealing with them. We show empirically that the proposed techniques significantly improve state-of-the-art solvers.
Healthcare-associated infections among patients in a large burn intensive care unit: incidence and pathogens, 2008-2012.

Burn injuries are a common source of morbidity and mortality in the United States, with an estimated 450,000 burn injuries requiring medical treatment, 40,000 requiring hospitalization, and 3,400 deaths from burns annually in the United States. Patients with severe burns are at high risk for local and systemic infections. Furthermore, burn patients are immunosuppressed, as thermal injury results in less phagocytic activity and lymphokine production by macrophages. In recent years, multidrug-resistant (MDR) pathogens have become major contributors to morbidity and mortality in burn patients. Since only limited data are available on the incidence of both device- and nondevice-associated healthcare-associated infections (HAIs) in burn patients, we undertook this retrospective cohort analysis of patients admitted to our burn intensive care unit (ICU) from 2008 to 2012.

Status of the SNS cryomodule test

The cryomodule tests are on going to have better understandings of physics as a whole and eventually to provide safe and reliable operation for neutron production. Some features are revealed to be interesting issues and need more attentions than expected, such as operating condition, collective effects between cavities, HOM coupler issues, end-group stability, cavity-coupler interactions, and vacuum/gas physics, waiting for more investigations. Up to now SNS cryomodules were mainly tested at 2.1 K/4.4 K, 10 pulse per second (pps) and 30 pps/60 pps tests are under progress. This paper presents briefly the experiences and the observations during tests of cryomodules.
Models for Inuktitut-English Word Alignment

This paper presents a set of techniques for bitext word alignment, optimized for a language pair with the characteristics of Inuktitut-English. The resulting systems exploit cross-lingual affinities at the sublexical level of syllables and substrings, as well as regular patterns of transliteration and the tendency towards monotonicity of alignment. Our most successful systems were based on classifier combination, and we found different combination methods performed best under the target evaluation metrics of F-measure and alignment error rate.
KELT: A Wide-Field Survey of Bright Stars for Transiting Planets

The Kilodegree Extremely Little Telescope (KELT) is a wide-field (26◦×26◦) robotic survey telescope currently operating in Sonoita, AZ. Assembled from commercial and off-theshelf devices, KELT currently surveys ∼ 40% of the Northern sky with sufficient precision to detect transiting planets around bright (8 < V < 12) stars. In the past several years of operation, over 30,000 science images have been acquired. Planet candidate selection and follow-up are currently underway. A brief overview of past and present survey operations, the data reduction pipeline, and initial results follows below. 1. Science Goals and Current Status Extra-solar planet discoveries of the past 10+ years have created a burgeoning new field in Astronomy. Following the design guidelines of Pepper et al. (2003), KELT was assembled to find the transiting planets around bright (8 < V < 12) stars. The brightest of these (8 < V < 10) have yet to be fully explored by current radial velocity and transit surveys. In addition to the many inherent advantages of transiting systems, the brightest systems lend themselves well to high precision follow-up and thus more sophisticated science programs. With its current survey parameters, KELT has been fully operational since mid 2006 and has acquired roughly 30,000 science images, each with several thousand stars at or below 1% photometry. At present, full-scale data reduction and candidate selection are underway.
Que: a sensor network rapid prototyping tool with application experiences from a data center deployment

Several considerable impediments stand in the way of sensor network prototype applications that wish to realize sustained deployments. These are: scale, longevity, data of interest, and infrastructure integration. We present a tool, Que, which assists those sensor network deployments transitioning from prototypes to early production environments by addressing these issues. Que is able to simulate realistic deployments with faithful data, provide fast and iterative feedback on operations, and compose applications quickly in a platform-independent manner. We demonstrate Que's applicability via tests against our new data center environment-monitoring deployment, DataCenter.NET.

Understanding Head and Hand Activities and Coordination in Naturalistic Driving Videos

In this work, we propose a vision-based analysis framework for recognizing in-vehicle activities such as interac- tions with the steering wheel, the instrument cluster and the gear. The framework leverages two views for activity analysis, a camera looking at the driver's hand and another looking at the driver's head. The techniques proposed can be used by researchers in order to extract 'mid-level' information from video, which is information that represents some semantic understanding of the scene but may still require an expert in order to distinguish difficult cases or leverage the cues to perform drive analysis. Unlike such information, 'low-level' video is large in quantity and can't be used unless processed entirely by an expert. This work can apply to minimizing manual labor so that researchers may better benefit from the accessibility of the data and provide them with the ability to perform larger-scaled studies. I. INTRODUCTION
Improving MPI-HMMER's scalability with parallel I/O

We present PIO-HMMER, an enhanced version of MPI-HMMER. PIO-HMMER improves on MPI-HMMER's scalability through the use of parallel I/O and a parallel file system. In addition, we describe several enhancements, including a new load balancing scheme, enhanced post-processing, improved double-buffering support, and asynchronous I/O for returning scores to the master node. Our enhancements to the core HMMER search tools, hmmsearch and hmmpfam, allow for scalability up to 256 nodes where MPI-HMMER previously did not scale beyond 64 nodes. We show that our performance enhancements allow hmmsearch to achieve between 48× and 221× speedup using 256 nodes, depending on the size of the input HMM and the database. Further, we show that by integrating database caching with PIO-HMMER's hmmpfam tool we can achieve up to 328× performance using only 256 nodes.
Spatial patterns of land surface phenology relative to monthly climate variations: US Great Plains

We extracted and mapped six land surface phenological metrics including: (1) the peak normalized difference vegetation index (NDVI), (2) peak date, (3) start of season (SOS), (4) end of season (EOS), (5) length of growing season (LOS), and (6) cumulative NDVI from 2000 to 2009 using Moderate-Resolution Imaging Spectroradiometer (MODIS) images covering the United States (US) Great Plains. Their patterns relative to monthly precipitation, maximum temperature, minimum temperature, and dew points were analyzed using multiple linear regression, stepwise selection, and geographically weighted regression (GWR) analysis. Both peak NDVI and cumulative NDVI had similar spatial patterns. Their values decreased along an east to west gradient. Peak date and SOS also showed compatible patterns. The southeastern Great Plains had the earliest SOS, peak date, and the longest LOS, given its warmer temperatures and greater precipitation. Dew points in March and October as well as the maximum temperature in April highly infl...
Combinatorial Chemistry as Applied to the Discovery of Agrochemicals

Combinatorial chemistry is a proven tool for lead generation and exploration in the discovery of novel therapeutic agents. In contrast, combinatorial chemistry approaches to lead generation for agrochemical discovery are in their infancy. This report summarizes the first reported examples of the application of combinatorial chemistry or parallel synthesis to the discovery of new fungicides, insecticides, and herbicides for crop protection. The synthesis and biological activity (in vitro or in vivo) of each compound library is described. The examples include the synthesis and testing of libraries of discrete small molecules as well as the preparation of pools of compounds and subsequent deconvolution of the active pools. Compound classes covered include amides, esters, ureas, N-substituted glycines and 2-amino-4-aryloxypyrimidines. These examples clearly demonstrate the potential of the technology to significantly impact the discovery of crop protection chemicals in the coming decade. Keywords: agrochemical discovery; 2-amino-4-aryloxypyrimidine; combinatorial chemistry; combinatorial library; fungicide; N-substituted glycine; herbicide; insecticide; insect nicotinic acatylcholine receptor; parallel synthesis; peptoid; N-phenylurea; pyrazolecarboxamide; scatalone dehydratase; solid-phase synthesis
Influence of translocation strategy and mating system on the genetic structure of a newly established population of island ptarmigan

Island populations and populations established by reintroductions are prone to extinction, in part because they are vulnerable to deterministic and stochastic phenomena associated with geographic isolation and small population size. As population size declines, reduced genetic diversity can result in decreased fitness and reduced adaptive potential, which may hinder short- or long-term population viability. We used 32 microsatellite markers to investigate the conservation genetics of a newly established population of Evermann’s Rock Ptarmigan (Lagopus muta evermanni) at Agattu Island, in the western Aleutian Archipelago, Alaska. We found low genetic diversity (observed heterozygosity = 0.41, allelic richness = 2.2) and a small effective population size (Ne = 28.6), but a relatively large Ne/N ratio = 0.55, which was attributed to multiple paternity in 80% of the broods and low reproductive skew among males (λ = 0.29). Moreover, successful breeding pairs were less related to each other than random male–female pairs. For conservation efforts based on reintroductions, a mating system with high rates of multiple paternity may facilitate retention of genetic diversity, thereby reducing the potential for inbreeding in small or isolated populations. Our results underscore the importance of quantifying genetic diversity and understanding the breeding behavior of translocated populations.
Preferred speed and cost of transport: the effect of incline

Preferred speed is the behavioral tendency of animals to utilize a relatively narrow set of speeds near the middle of a much broader range that they are capable of using within a particular gait. Possible explanations for this behavior include minimizing musculoskeletal stresses and maximizing energetic economy. If preferred speed is determined by energetic economy (cost of transport, CT), then shifts in preferred speed should produce shifts in CT. To test this hypothesis, preferred speeds were measured in trotting horses on the level and on an incline. The preferred trotting speed decreased from 3.29±0.24 m s -1 on the level to 3.05±0.30 m s -1 (means ± S.D., N=6) on an 11.8 % incline. The rate of oxygen consumption was measured as a function of trotting speed on a treadmill and was a curvilinear function of speed in all horses under both conditions (level and 10 % incline). This curvilinear relationship resulted in a CT that was a U-shaped function of speed. The speed at which CT was minimal (i.e. at which trotting was most energetically economical) was very near the preferred speed on the level and decreased on the incline, again to a speed near the preferred speed on the incline. Summary
Neural networks in RSCAD for intelligent real-time power system applications

Addition of load and generation over the existing transmission lines over the past several years has added to the complexity of the electric power network. Smart grid will have high uncertainty and variability owing to high penetration of intermittent energy sources such as wind and solar. At the same time, higher efficiencies and reliability is demanded and the electrical power network is being pushed closer to its operating limits. New equipments and technologies are being developed in order to cope with these requirements. It is necessary to have real-time simulation of power system phenomena, components, and intelligent methods of monitoring, communication and control under these changed scenarios in order to ensure stability, reliability, integrity and security of the electric power grid. The RTDS®, along with its graphical interface RSCAD, provides the ability to design and simulate power systems and controls, and perform hardware-in-the-loop studies. In this paper, neural networks (NN) library developed for RSCAD is applied to intelligent power system applications. The results show that the NN library developed in RSCAD can be an important tool in the study and development of intelligent methods for smart grid applications.
Beyond the stained back-drop

A 63-year-old-man presented to hospital with progressive low-back pain over the last 3 months. He also reported weight loss of 30 lbs in last 3 months. MRI of lower spine revealed 1 cm left-sided intradural extramedullary enhancing lesion at S1-level, with mass effect on the thecal sac (figure 1A,B). Given the clinical history and location of the lesion, MRI of the entire spine (cervical, thoracic and lumbosacral region), and brain were ordered to rule out drop metastasis. Brain MRI showed ring enhancing lesion with a fluid level in the left frontal lobe (figure 1C,D). Cervical spine MRI revealed a midline soft tissue enhancing mass (figure 1E,F). Brain lesion and cervical soft tissue mass were excised surgically. Histopathology revealed hyperchromatic …
Confocal imaging of transmembrane voltage by SEER of di-8-ANEPPS

Imaging, optical mapping, and optical multisite recording of transmembrane potential (Vm) are essential for studying excitable cells and systems. The naphthylstyryl voltage-sensitive dyes, including di-8-ANEPPS, shift both their fluorescence excitation and emission spectra upon changes in Vm. Accordingly, they have been used for monitoring Vm in nonratioing and both emission and excitation ratioing modes. Their changes in fluorescence are usually much less than 10% per 100 mV. Conventional ratioing increases sensitivity to between 3 and 15% per 100 mV. Low sensitivity limits the value of these dyes, especially when imaged with low light systems like confocal scanners. Here we demonstrate the improvement afforded by shifted excitation and emission ratioing (SEER) as applied to imaging membrane potential in flexor digitorum brevis muscle fibers of adult mice. SEER—the ratioing of two images of fluorescence, obtained with different excitation wavelengths in different emission bands—was implemented in two commercial confocal systems. A conventional pinhole scanner, affording optimal setting of emission bands but less than ideal excitation wavelengths, achieved a sensitivity of up to 27% per 100 mV, nearly doubling the value found by conventional ratioing of the same data. A better pair of excitation lights should increase the sensitivity further, to 35% per 100 mV. The maximum acquisition rate with this system was 1 kHz. A fast “slit scanner” increased the effective rate to 8 kHz, but sensitivity was lower. In its high-sensitivity implementation, the technique demonstrated progressive deterioration of action potentials upon fatiguing tetani induced by stimulation patterns at >40 Hz, thereby identifying action potential decay as a contributor to fatigue onset. Using the fast implementation, we could image for the first time an action potential simultaneously at multiple locations along the t-tubule system. These images resolved the radially varying lag associated with propagation at a finite velocity.
Reversal of Penicillin-Induced L-Phase Growth of Haemophilus influenzae by Spermine and Its Effects on Antibiotic Susceptibility

Spermine at a concentration of 0.001 m initiated the reversion of penicillin-induced L-phase growth of Haemophilus influenzae to bacillary growth on penicillin L-phase medium. Reversion of L-phase colonies to bacillary colonies required 3 to 5 days. This spermine reversal of variant growth also occurred on penicillin induction medium in the presence of concentrations of tetracycline, erythromycin, and chloramphenicol that were not bactericidal for L-phase or bacillary inocula until 48 or more hr. Spermine was without protective effect against streptomycin and kanamycin, which were, in combination with penicillin, bactericidal at 24 hr. Spermine protection of L-phase variants against antibiotic toxicity was, therefore, related to initiation (by spermine) or bacillary growth from round bodies that survived for 24 or more hr at bacteriostatic levels of antibiotic.
Setting Rules for Post-ablation and Follow-Up

Focal therapy has emerged as a less aggressive treatment alternative for a highly select group of men with early stage prostate cancer. Despite advances in ablative technology and imaging, focal therapy is still considered to be experimental or investigative by most centers. In addition, focal therapy has been broadly defined including a wide range of treatment modalities and templates. As a result of these issues, no standardized criteria or consensus protocols have been adopted for post-ablation oncological and functional follow-up and surveillance. In an effort to move closer to the adoption of a more unified approach, we review the relevant literature and suggest guidelines for post-ablation biopsies, use of PSA data, imaging, patient functional evaluation, and reporting of side effects.
Estrogen and progesterone receptors in lymphangioleiomyomatosis, epithelioid hemangioendothelioma, and sclerosing hemangioma of the lung.

The therapeutic options in the treatment of lung neoplasia usually have not included hormonal therapy, unlike those for primary tumors of other sites (e.g., breast). However, two mesenchymal proliferations of lung, lymphangioleiomyomatosis and epithelioid hemangioendothelioma (EHE), and one epithelial tumor, sclerosing hemangioma (SH), have a significant female predilection and may benefit from such hormonal therapy. The authors investigated five cases each of EHE and lymphangioleiomyomatosis and four cases of SH for expression of estrogen and progesterone receptors and 17-beta estradiol in paraffin-embedded tissue. Only one case each of lymphangioleiomyomatosis and The therapeutic options in the treatment of lung neoplasia usually have not included hormonal therapy, unlike those for primary tumors of other sites (e.g., breast). However, two mesenchymal proliferations of lung, lymphangioleiomyomatosis and epithelioid hemangioendothelioma (EHE), and one epithelial tumor, sclerosing hemangioma (SH), have a significant female predilection and may benefit from such hormonal therapy. The authors investigated five cases each of EHE and lymphangioleiomyomatosis and four cases of SH for expression of estrogen and progesterone receptors and 17-beta estradiol in paraffin-embedded tissue. Only one case each of lymphangioleiomyomatosis and EHE expressed 17-beta estradiol. All of the other cases were negative. These findings are contrary to the viewpoint held in published literature, especially in case reports of lymphangioleiomyomatosis, describing patients with positive estrogen and progesterone receptor results. Consequently, a number of issues must be considered in the clinical and immunohistochemical evaluation of the estrogen and progesterone receptor status of these rare pulmonary neoplasms.
Void structure and permeability of paper relative to that of wood

SummarySignificant positive associations were found between urinary taurine excretion and 2 measures of adaptive behavior, cottage placement and I.Q. scores. The correlation ratio between cottage placement and taurine excretion was Eyx = .41. I.Q. score regressed on taurine excretion yielded a coefficient of .32. Both associations are significant at the 5% level.
Non–vitamin K antagonist oral anticoagulant reversal: hope is on the horizon

Abstract Background Non–vitamin K oral anticoagulants have become an attractive alternative to warfarin when patients require anticoagulation. Until recently, one of the biggest challenges to these agents was the lack of specific reversal of their anticoagulation when bleeding occurs or urgent/emergent procedures are required. Data Sources This article is a narrative review of peer-reviewed publications with particular attention to authors that are experts in the field, society guidelines, and government publications. Conclusions Development of several drugs has led to agent-specific reversal. Idarucizumab has gained approval in the United States for reversal of dabigatran. Andexanet alfa has completed promising phase III trials for the reversal of factor Xa inhibitors. Aripazine (PER977) has shown promise as a universal reversal agent against non–vitamin K antagonist oral anticoagulants and heparin products.
A Framework for Boosting Revenue Incorporating Big Data

Complex industry partnerships, innovative strategies, and cross-cutting industry competition, challenge business leaders in making strategic and operational decisions that support growth and competitiveness. Companies seeking to inform their business decisions by leveraging “big data” face challenges in processing and analyzing such large and rapid datasets. However leveraging big data can create value for businesses. Although various frameworks exist for implementing analytics, few accommodate the implementation of big data analytics. Our goal is to develop a framework by studying big data on a micro and macro level and examining how companies can use big data to boost revenue through creating value. This research is augmented by an in-depth examination of industry giant Amazon.com. Our results provide a framework that enhances traditional analytical frameworks through the integration of big data analytics. Our findings indicate that an integrated framework provides enhanced insights to decision makers seeking to create value for their businesses.

Surgical outcome of spelenectomy in Thalassemia major in children.

OBJECTIVE To determine the surgical outcome of splenectomy in children with thalassemia major. METHODS It is an observational and descriptive study conducted in Department of Paediatric Surgery in collaboration with hematology, radiology, anesthesia and paediatric intensive care department at The Children's Hospital and the Institute of Child Health, Multan during the period of September 2007 to September 2013. A total of 50 patients suffering from thalassemia major already diagnosed and under management reffered from haematology department for splenectomy were included in this study. After admission, patients were assessed on the basis of history, clinical examination, and necessary investigations before surgery and later on follow-up. Investigations carried were CBC, PT, APTT, Viral markers, ECG, X-ray Chest, abdominal ultrasonography and ECHO if necessary. Splenectomy was performed after prophylactic vaccination against post splenectomy infections. Follow up was performed for at least two years. Blood transfusion requirements and number of hospital visits per annum before and after splenectomy were calculated and results analyzed statistically using SPSS-20. RESULTS Fifty patients were included in this study. Out of these fifty, 43 (86%) male and 7(14%) were female with a mean age of 9 years. Average blood transfusion requirement was 250 ml/kg/year, interval of blood transfusion was two weeks and twenty five visits per year before splenectomy. After splenectomy, requirement of blood transfusion reduced to 125ml/kg/year, interval between transfusion increased to one month and hospital visits reduced up to twelve per year. CONCLUSION Blood transfusion requirement and number of hospital visits per year are decreased and interval between transfusions is increased after splenectomy. Splenectomy should not be delayed when indicated. Preoperative vaccination decreases the chance of post splenectomy infection.
Impact of cytogenetic abnormalities on outcome of bone marrow transplants in acute myelogenous leukemia in first remission.

This study analyzed the impact of cytogenetic abnormalities on outcome of 1516 HLA-identical sibling bone marrow transplants for acute myelogenous leukemia (AML) in first remission reported to the International Bone Marrow Transplant Registry by 188 centers. 708 patients (47%) had cytogenetic studies performed. Transplant outcome in these subjects was similar to the 808 in whom cytogenetic studies were not performed. One or more cytogenetic abnormalities were detected in 284 (40%) of subjects studied. Relapse rates were higher and leukemia-free survival lower in patients with poor prognosis abnormalities vs those with no abnormality or with good or intermediate prognosis abnormalities (relative risk of relapse 2.40, P < 0.01 ; relative risk of treatment failure 1.68, P < 0.03). We conclude that cytogenetic abnormalities correlated with increased relapse in patients treated with chemotherapy. HLA-identical sibling transplants are similar.
The World of the Cell

Man’s imagination has always been captivated by the thought of unexplored worlds, of lands and planets other than our own. The cell is a wonderful world discovered almost three hundred years ago and still but partially explored. This is the world—a complex, fascinating, and often beautiful world—that will be considered in this volume. The major aim will be to examine the cell and its parts as a combination of form and function. We will first consider the development of knowledge about the cell.
Social distance and network structures: Social distance and network structures

This paper proposes a tractable model that allows us to analyze how agents' perception of relationships with others determines the structures of networks. In our model, agents are endowed with their own multidimensional characteristics and their payoffs depend on the social distance between them. We characterize the clustering coefficient and average path length in stable networks, and analyze how they are related to the way agents measure social distances. The model predicts the small-world properties under a class of social distance that violates the triangle inequality. Allowing for heterogeneity in link-formation costs, the model also accommodates other well documented empirical patterns of social networks such as skewed degree distributions, positive assortativity of degrees, and clustering-degree correlation.
Silicon carbide phononic crystals for high f.Q micromechanical resonators

This paper demonstrates silicon carbide phononic crystal cavities for RF and microwave micromechanical resonators. We demonstrate design and simulation of silicon carbide/air phononic crystals used as Bragg acoustic mirrors to confine energy in a silicon carbide cavity. Aluminum nitride piezoelectric transducers are used for drive and sense of silicon carbide overtone cavities at 2.3GHz with quality factors exceeding 3,500 in air. This approach enables decoupling of the piezoelectric material from the cavity quality factor, resulting in high f.Q products at microwave frequencies. The silicon carbide phononic crystal cavities are fabricated in a CMOS-compatible process, for integration in wireless communication systems.
A Fuzzy Logic Controller Design for Nuclear Power Plant

Abstract A fuzzy logic controller design for a wide-range reactor temperature control is presented. Typically, fuzzy logic controllers are designed based on expert's knowledge of the process. However this approach has its limitations in the fact that the controller is hard to optimize. In this paper a method to automate the optimizing process using a simplified Kalman filter approach is presented. The resulting controller displayed good stability and performance robustness characteristics for a wide range of operation.
Observation of an fcc–Co nanolayer grown between CoO and amorphous Si

The thermodynamically crystallographic phase of Co at ambient conditions is hexagonal-close-packed. However, it has been found that given a crystallographic support from a suitable substrate, the high-temperature face-centered-cubic phase can be stabilized in thin films. We performed cross-sectional high-resolution transmission electron microscopy on a Si substrate/Si buffer/Co/CoO/Cu$$_{41}$$ Ni$$_{59}$$ /Nb/Cu$$_{41}$$ Ni$$_{59}$$ /Si-cap heterostructure (all layer thicknesses in the nanometer range). We analyzed lattice spacings and angles of the Co layer and neighbouring layers. While in the present study, there is no obvious support for an fcc structure by the amorphous Si buffer and the CoO (spinel structure), only an fcc phase of the Co layer (of about 5 nm thickness) is in agreement with the obtained results. However, the detailed mechanism of phase stabilization remains unresolved.

Lack of Consensus in Physician Recommendations Regarding Return to Driving After Cervical Spine Surgery.

Study design A cross-sectional study. Objective The goal of this study is to investigate how surgeons differ in collar and narcotic use, as well as return to driving recommendations following cervical spine surgeries and the associated medico-legal ramifications of these conditions. Summary of background data Restoration of quality of life is one of the main goals of cervical spine surgery. Patients frequently inquire when they may safely resume driving after cervical spine surgery. There is no consensus regarding postoperative driving restrictions. This study addresses how surgeons differ in their recommendations concerning cervical immobilization, narcotic analgesia, and suggested timeline of return to driving following cervical spine surgery. Methods Surgeons at the Cervical Spine Research Society annual meeting completed anonymous surveys assessing postoperative patient management following fusion and nonfusion cervical spine surgeries. Results Seventy percent of surgeons returned completed surveys (n = 71). About 80.3% were orthopedic surgeons and 94.2% completed a spine fellowship. Experienced surgeons (>15 years in practice) were more likely to let patients return to driving within 2 weeks than less experienced surgeons (47.1% vs. 24.3%, P = 0.013) for multilevel anterior discectomy and fusion (ACDF) and laminectomy with fusion procedures. There were no differences between surgeons practicing inside and outside the USA for prescribing collars or return to driving time. Cervical collars were used more for fusions than nonfusions (57.7% vs. 31.0%, P = 0.001). Surgeons reported 75.3% of patients ask when they may resume driving. For cervical fusions, 31.4% of surgeons allowed their patients to resume driving while restricting them with collars for longer durations. Furthermore, 27.5% of surgeons allowed their patients to resume driving while taking narcotics postoperatively. Conclusion This survey-based study highlights the lack of consensus regarding patient "fitness to drive" following cervical spine surgery. The importance of establishing evidence-based guidelines is critical, as recommendations for driving in the postoperative period may have significant medical, legal, and financial implications. Level of evidence 5.
Some Combinatorially Defined Matrix Classes

In this section we consider the symmetric group of permutations of a finite set and their partial order known as the Bruhat order. Regarding a permutation as a permutation matrix, this partial order is related to Gaussian elimination and leads to the matrix Bruhat decomposition of a nonsingular matrix, and then to a characterization of ags in a vector space. We also describe a correspondence between permutations that are involutions (symmetric permutation matrices) and a certain class of nonnegative integral matrices.
Pipeline Embolization for Salvage Treatment of Previously Stented Residual and Recurrent Cerebral Aneurysms

Introduction This study assessed the safety and effectiveness of the Pipeline embolization device (PED) for persistent and recurrent aneurysms previously treated with either a vascular reconstruction device (VRD) or a flow diverter (FD). Methods A prospective, IRB-approved database was analyzed for patients treated with PED for aneurysms previously treated with a stent. Results Twenty procedures were performed on 18 patients, 11 with prior FD, 7 with VRD, and 2 previously treated with both. Overall, 15 aneurysms were saccular (75%), and size was 13.5 ± 7.6 mm. Location was internal carotid artery (ICA) in 14 cases (70%) and posterior circulation in 6 cases (30%). Average prior treatments were 1.7. Previously FD cases were re-treated at an average of 18.1 months from most recent treatment. Each case used 1 device, 82% with distal coverage and 82% with proximal coverage of prior stent. Balloon remodeling was performed in 3 cases (27%) and no in-stent thrombosis was observed. Previously VRD stent-coiled cases were re-treated at an average of 87.5 months. These cases used on average 1.9 devices, 89% with distal and 100% proximal coverage. Adjunctive coiling was performed in 1 case (11%), balloon remodeling in 5 cases (56%), and 2 cases (28%) developed thrombosis that resolved with abciximab. Re-VRD cases were longer (59.1 vs. 33.7 min, p = 0.02) than re-FD. Angiographic follow-up was available for 16 cases (80%). In re-FD, occlusion was complete in 56% and partial progressive in 33% at 17.1 months digital subtraction angiography. In re-VRD, occlusion was complete in 57% and partial progressive in 27% at 8.1 months. Two complications occurred (10%), including one asymptomatic cervical ICA occlusion and one stent occlusion with associated mortality (5%). Clinical follow-up was 17.8 months on average (range 0.5-51.9). Conclusions Salvage flow diversion for previously stented aneurysms is technically challenging but offers good prospects of aneurysm obliteration with acceptable complication rates.
Anger and Aggression Among Military Personnel

The nature of the military, with regard to both its organizational mission and its training procedure, inherently involves the occurrence of anger and aggression. Although this point is obvious, there is no existing delineation of the forms that these phenomena take in military organizations, and there is little systematic work on the environmental determinants of anger and aggression among military personnel outside of combat. Yet, various conditions of the training regimens, role strain, and interpersonal conflict within an authoritarian organizational structure can induce strong emotions and result in either direct or displaced hostility.
Ontology Development and its Utility in QTL Data Annotation

Two ontologies have been developed to characterize traits in vertebrate species. The Vertebrate Trait Ontology (VT) is a vocabulary of terms describing measurable or observable characteristics related to the morphology, physiology, or development of vertebrates. The livestock Product Trait Ontology (PT) defines those characteristics relevant to products produced by or obtained from animals maintained for use and/or profit. Both ontologies are being used to annotate data in the Animal QTL Database, providing a common basis for comparisons across databases or between species. The VT and PT will benefit the livestock production industry by implementing standardized trait nomenclature to enhance animal improvement accuracy and to unambiguously utilize research outcomes.
Fascial manipulation vs. standard physical therapy practice for low back pain diagnoses: A pragmatic study.

Abstract Background Connective tissue mobility alters motor unit recruitment, but the restoration of fascial mobility allows for optimal motor function. The Fascial Manipulation® (FM®) method is a multiplanar approach that assesses and treats the mobility of deep fascia in specific anatomical locations where motor units converge. Objectives To assess the effects of FM® vs. standard physical therapy treatment (SPT) in patients with low back pain (LBP). Design Six-months controlled clinical trial. Method 102 participants with LBP received SPT or FM®. Numeric Pain Rating Scale (NPRS), 15- point Global Rating of Change (GROC), and Oswestry Disability Index (ODI) were used to monitor progress. Results The FM® group had a significantly lower ODI (p Conclusions FM® appears to improve NPRS, GROC, and ODI more than SPT. FM® may provide an effective treatment technique for LBP.
Metal-Alkyne and Metallacyclobutene Reactivity toward a Diazoacetamide: Conversion to Highly Functionalized 1,3-Diene Complexes and Oxametallacyclopentadienes

Here we report the first reactions of metal-alkyne and metallacyclobutene complexes with a diazoacetamide. Reaction of (η5-C5H5)(PPh3)Co[η2-(R3Si)C≡C(SO2Ar)] (1-TMS, R = Me, Ar = C6H5; 1-TIPS, R = CH(CH3)2, Ar = p-C6H4CH3) and 2-diazo-N,N-dimethylacetamide, N2CH(CONMe2) (7), produces the oxametallacyclopentadiene complexes (η5-C5H5)(SO2Ar)Co[κ2-O═C(NMe2)CC(H)═C(R3Si)] (8-TMS, R = Me, Ar = C6H5; 8-TIPS, R = CH(CH3)2, Ar = p-C6H4CH3). The conversion of 1 and 7 to 8 involves the loss of PPh3, two nitrogen atoms, and a single carbon atom from the starting materials, as well as cleavage of a carbon–sulfur bond and formation of a sulfinato (−SO2Ar) ligand. The cobalt-alkyne complex, (η5-C5H5)(PPh3)Co(η2-PhC≡CPh) (1-Ph), undergoes reaction with 7 to give the cobalt-diene complex (η5-C5H5)Co[η4-(Z,E)-CH(CONMe2)═CPhCPh═CH(CONMe2)] (9-ZE). Treatment of the cobaltacyclobutene, (η5-C5H5)(PPh3)Co[κ2-(3-ethoxycarbonyl)-1-(phenylsulfonyl)-2-(trimethylsilyl)-1-propene-1,3-diyl] (3-TMS), with 7 leads to regio- and diaster...
