Low-Complexity Distributed Compression in Wireless Sensor Networks

In this paper, we develop a distributed compression technique that has low decoding and encoding computational complexity. The proposed scheme exploits both temporal and spatial correlations between nodes in distributed sensor networks. In case of events occurring, the values of both spatial and temporal might change and the compression technique needs to adjust its rate to the changes automatically. Our proposed algorithm reactively changes its compression rate to adapt to the variations in the correlations. This algorithm uses the well-known compressive sensing algorithm to exploit the spatial correlation. Rate less codes were adopted to generate the measurements. The number of measurements are adjusted based on the temporal correlations among sensors. When sensor readings are changing slowly, the compression rate is improved by reducing the number of measurements. In case of any event that significantly changes the signal readings, the algorithm generates more measurements to guarantee recovery of signal at the base station. The experimental results done over data gathered by 64 temperature sensors and also Matlab simulation results reveal that our algorithm is flexible to adapt the variations in the sensor readings, while it keeps the compression rate the minimum.
Linguistic landscape as a reflection of the linguistic and ideological conflict in the Valencian Community

Abstract The Valencian Community is an area in Spain where Valencian, a variety of Catalan, is the co-official language along with Spanish. Differently from other bilingual areas in Spain, the unique historical circumstances that the Valencian Community underwent have led to the current linguistic and ideological conflict in the area. The historical division between Spanish versus Valencian, with Spanish being the high prestige language, was reinforced during Franco's dictatorship. After Franco's death, there was a slow process of language normalisation intended to reinforce the use of the local language. In Valencia, this situation was hindered by the birth of a secessionist movement claiming that Valencian and Catalan were two different languages. This ideological situation frames the language policy in Valencia and is reflected in the public space. This paper analyses 248 linguistic landscape items collected in two urban sites representing public and private institutions. The data uncover existing conf...
Determination of the Relative Partial Molar Enthalpy of Decyldimethylphospine Oxide in H2O and D2O at 25°C

The relative partial molar enthalpy of decyldimethylphosphine oxide has been determined in H2O and D2O from infinite dilution to about 8 mm at 25°C. The shapes of the resulting curves resemble those previously reported for ionic but not nonionic surfactants and are inconsistent with existing models of micelle formation. The enthalpy of micelle formation (corresponding to the maximum value of the relative partial molar enthalpy of the surfactant) was 12,900 ± 200 cal/mol in H2O and 10,600 ± 200 cal/mol in D2O. The cmc was lower in D2O than in H2O as expected (3.64 versus 4.2 mm).

Polychlorinated Dibenzo-p-dioxins and Dibenzofurans in Sediments from Siskiwit Lake, Isle Royale

Polychlorinated dibenzo-p-dioxins and dibenzofurans were found in sediment from Siskiwit Lake on Isle Royale, Lake Superior, a location which can receive only atmospheric inputs. The source of these compounds is the atmospheric transport of dioxins and furans formed by combustion of domestic and chemical waste.
Image processing and data acquisition optimization for acoustic radiation force impulse imaging of in vivo breast masses

Acoustic Radiation Force Impulse (ARFI) imaging utilizes brief, high-energy acoustic pulses to excite tissue and ultrasonic correlation based tracking methods to monitor the resulting tissue displacement, which reflects the relative mechanical properties of tissue (i.e. stiffer tissue displaces less). ARFI image contrast is optimized utilizing tightly focused radiation force excitations at multiple axial and lateral locations throughout a 2D field of view. In an ongoing, IRB approved, clinical study, suspicious breast lesions are interrogated in vivo via multi-focal-zone ARFI prior to undergoing core biopsy. A Siemens SONOLINE Antares (TM) scanner and VF10-5 probe were configured to acquire ARFI data from multiple focal-zones and lateral locations. Data was acquired in real-time, and processed off-line. Processing included: filtering, parametric data analysis, normalization and combination of the multiple focal-zone data, and automatic edge detection. ARFI sequences were designed with varying pushing pulse frequencies and intensities. Contrast to noise ratio was evaluated in a tissue mimicking phantom for lesions at different depths using the different pushing pulse sequences. For shallower lesions (depth=10mm), CNR was higher than for deeper lesions, and did not vary appreciably for the different push sequences. For deeper lesions (depth=20mm), CNR increased with increasing push pulse intensity and decreasing push pulse frequency. With the pushing pulse transmit intensity calibrated (in a homogeneous phantom) to achieve uniform displacement at all axial depths, in vivo results yielded poor SNR at depth and did not achieve overall uniform displacement. In vivo, image quality improved with increasing push pulse intensity. To date, 27 masses have been interrogated using multi-focal-zone ARFI and overall good structural agreement exists between B-mode and ARFI images. Normalization and blending facilitate image generation from ARFI interrogation using different intensities at different focal depths.
Standard measures of right ventricular function assessment in adult patients with acute sickle cell crises.

Abstract Chronic sickle cell (SC) disease is known to cause pulmonary hypertension (PH) which eventually affects right as well as left ventricular function. However, the acute effects of SC crisis on right ventricular (RV) function in adults have not been well described. Our echocardiography database was queried for patients followed in the outpatient hematology clinic, who were admitted with SC crises, and had an inpatient echocardiogram. Comparisons of RV fractional area change (RVFAC) and tricuspid annular peak systolic excursion (TAPSE) were then made to a group of healthy patients and a group with mild PH. TAPSE was normal in patients with SC disease (3.05±0.56). However, the SC patients had significantly larger RV's compared to controls and mild PH patients (31.33±7.23 cm 2 vs. 19.07±4.49 cm 2 and 21.51±6.07 cm 2 , respectively, P P =0.4). We found no correlation between hemoglobin level (8.1±2.5 g) and RVFAC, TAPSE, or PH severity. We found that adult patients admitted with SC crises have frequent dilatation of the RV with an abnormal reduction in RVFAC, despite normal TAPSE values. Therefore, caution should be exercised in using TAPSE to estimate RV function in this patient population.

Correlations in the structure and function of human placental lactogen and human growth hormone. I. Modification of the disulfide bonds.

The two disulfide bonds of human placental lactogen (hPL) and human growth hormone (hGH) were chemically modified, and the lactogenic and immunologic activities of the derivatives were compared with those of the native unmodified hormones. Reduction and alkylation with iodoacetamide and iodoacetic acid selectively disrupted the two bonds, resulting in the formation of the S—carbamidomethyl and S—carboxymethyl derivatives, respectively. Performic acid oxidation converted the half—cystine residues to cysteic acid, oxidized the methionine residues to methionine sulfone and destroyed the single tryptophan residue in each hormone. The lactogenic potency of the derivatives, as measured by the stimulation of casein synthesis in vitro in mammary gland explants, was completely retained; immunologic activity, on the other hand, was markedly decreased or abolished. Neither the tertiary structure contributed by the two disulfide bonds in each molecule nor the presence of intact methionine and tryptophan residues is e...
A Modular Organization of the Human Intestinal Mucosal Microbiota and Its Association with Inflammatory Bowel Disease

Abnormalities of the intestinal microbiota are implicated in the pathogenesis of Crohn's disease (CD) and ulcerative colitis (UC), two spectra of inflammatory bowel disease (IBD). However, the high complexity and low inter-individual overlap of intestinal microbial composition are formidable barriers to identifying microbial taxa representing this dysbiosis. These difficulties might be overcome by an ecologic analytic strategy to identify modules of interacting bacteria (rather than individual bacteria) as quantitative reproducible features of microbial composition in normal and IBD mucosa. We sequenced 16S ribosomal RNA genes from 179 endoscopic lavage samples from different intestinal regions in 64 subjects (32 controls, 16 CD and 16 UC patients in clinical remission). CD and UC patients showed a reduction in phylogenetic diversity and shifts in microbial composition, comparable to previous studies using conventional mucosal biopsies. Analysis of weighted co-occurrence network revealed 5 microbial modules. These modules were unprecedented, as they were detectable in all individuals, and their composition and abundance was recapitulated in an independent, biopsy-based mucosal dataset 2 modules were associated with healthy, CD, or UC disease states. Imputed metagenome analysis indicated that these modules displayed distinct metabolic functionality, specifically the enrichment of oxidative response and glycan metabolism pathways relevant to host-pathogen interaction in the disease-associated modules. The highly preserved microbial modules accurately classified IBD status of individual patients during disease quiescence, suggesting that microbial dysbiosis in IBD may be an underlying disorder independent of disease activity. Microbial modules thus provide an integrative view of microbial ecology relevant to IBD.
Hindered rotation in N-methylformamide. A peptide-bond model system*†

Summary Barriers to rotation about the C-N bond in the cis and trans isomers of N-methylformamide have been determined by n.m.r. spectroscopy. Representative values are 20.7 and 22.0 kcal/mole. Arrhenius parameters have also been determined. These results are compared with C-N barriers for N,N-dimethylformamide and unsubstituted formamide. The data suggest that C-N rotational barriers for N-methyl amides may be similar to those for their N,N-dimethyl derivatives.
Neurodevelopmental Predictors in Extra Corporeal Membrane Oxygenation (ECMO) and Near ECMO Survivors at 2.5 to 6 years of Age 1685

A Comparative Study of Locally Conservative Numerical Methods for Darcy's Flows

Abstract This paper presents a comparative study on locally mass-conservative numerical methods for Darcy's flows. The classical mixed finite element method (MFEM) is compared with the newly developed discontinuous finite volume method (DFVM) with and without weak over-penalization (WOP). These numerical methods are tested on three representative problems in porous media flows. In particular, locality, accuracy of numerical solutions, computational costs, and implementation issues are examined. The study indicates that the discontinuous finite volume methods could be viable alternatives to the classical mixed finite element method for Darcy's flows.
A Study on Solid Phase Reactions of Ni and Pt on Si-Ge Alloys as Contacts to Ultra-Shallow P+N Junctions for CMOS Technology Nodes Beyond 70nm

Recently, selectively deposited SiGeB alloys have been proposed to form ultra-shallow source/drain junctions for 35-70 nm CMOS. The technology provides super-abrupt junctions with above equilibrium dopant activation at temperatures lower than 800°C. In addition to their low resistivities, the lower bandgap of SiGeB provides the potential advantage of reducing the Schottky barrier height and therefore, the junction contact resistance. This is a critical concern for future CMOS technology nodes since the contact resistance will dominate the MOSFET series resistance unless new technologies yielding contact resistivities near 10−8 ω−cm2 are developed. This paper examines the solid phase reactions of Ni and Pt with SiGeB alloys in order to form self-aligned low resistivity contacts. The results show that both Ni and Pt can form germanosilicides with low sheet resistances. Furthermore, both metals can form self-aligned contacts with a contact resistivity near 10−8 ω−cm2.

A flexible model for quantitative comparisons of nitrogen mineralization patterns

Patterns of N mineralization vary widely between ecosystems, making intra- and interexperimental comparisons difficult at best. A flexible model, the Richards model, is suggested as a way of making comparisons. By changing its shape parameter, a flexible model can fit multiple mechanistic models, including first-order and logistic models. The scale-independent shape parameter (m) is a continuous variable that can be statistically analyzed to determine changes or differences in patterns. The model was tested with (1) simulations based on other mechanistic models; and with N mineralization data on soils from (2) urban and rural sites in New York; (3) forest soils in Alberta, Canada; and (4) arid and semiarid soils in Morocco. In all examples, the model was capable of fitting the data nearly as well as other specific models. With data based on the m values, soils in Morocco and organic horizons of coniferous forests in Alberta showed the same range in N mineralization patterns, although the soils varied in the amount of mineralizable N by an order of magnitude and time to reach maximum mineral N production by two-fold.
An electron microscopic study of chloroplast condition in summer and winter inPinus strobus

1. When leaf and bark tissues ofPinus strobus were fixed in osmium, embedded in methacrylate, and sectioned, winter-type chloroplasts appeared as distinct, intact entities under the electron microscope, although often closely appressed to one another in the folds or sides of the cells. 2. Grana and lamellae were clearly visible in winter as well as in summer; the principal change from summer to winter appeared to be the loss of starch and perhaps also “fat droplets”. 3. The larger size of the summer chloroplasts is apparently the result of starch grain growth, but may also be caused by partial vacuolization of chloroplasts in summer. Permanganate-fixed bark cells contained unvacuolated chloroplasts in summer. 4. In winter, a network or reticulmn occurred in all living cells, apparently emeshing mitochondria as well as chloroplasts, and in sieve cells extending through the plates. In summer, this reticulum appeared to be less extensive than in winter.
Study of the resistance behavior of anatase and rutile thick films towards carbon monoxide and oxygen at high temperatures and possibilities for sensing applications

Abstract The resistance changes of thick films of titania were examined in the presence of CO at elevated temperatures ranging from 500 to 1000 °C. Three materials were examined, commercial samples of anatase and rutile and a Cr3+-doped rutile prepared in the laboratory. The anatase film exhibited a n-type response to both oxygen and CO in the tested O2 range of 2–21% and CO from 10 to 2000 ppm at 600 °C, with the response disappearing beyond 700 °C. On the other hand, the rutile films showed an entirely different electrical behavior. Until 1000 °C, p-type response was observed to oxygen concentrations from 2 to 21%. With CO concentrations up to 2000 ppm, p-type behavior was observed in 2–21% oxygen concentrations between 600 and 700 °C. However, when the temperature was above 750 °C, an n-type behavior to CO with concentrations ranging from 200 to 2000 ppm was observed, and response was observed until 850 °C. A coating of colloidal platinum on the rutile film induced a transition of the response of the thick film from p to n-type to both oxygen and CO at 600 °C. With the Cr-rutile sample, p-type behavior was observed for both CO and O2. The possible mechanisms for the observed p–n transition of the two rutile films are discussed. Strategies for developing CO sensors for high temperature applications based on the above observations are formulated.
Abstract 4034: The role of CYP33 in MLL target gene repression

This study further elucidates the role of CYP33 in gene transcription by studying the effects of CYP33 overexpression and siRNA-mediated down-regulation on the expression of MLL target genes such as c-MYC, p21, p27, and HOXA9. CYP33 is a cis-trans prolyl isomerase (PPIase) which mediates repression of HOX gene expression after binding to the 3 rd PHD finger of MLL through its own RRM domain. Upon binding to MLL, CYP33 increases recruitment of HDAC to the MLL repression domain which in turn leads to deacetylation of histone H3. This ultimately causes repression of MLL target genes (Xia et al. 2003). Chromosomal translocations involving the MLL gene (Mixed Lineage Leukemia) can lead to the production of fusion proteins with any of more than 60 different partner proteins and is implicated in the initiation of leukemia. Expression of MLL fusion proteins leads to increased expression of MLL target genes such as HOXA7, HOXA9 and MEIS1 (Hess et al., 2010). MLL-fusion proteins lack the 3 rd PHD finger and therefore, lose their ability to bind CYP33; in the presence of these fusion proteins CYP33 can no longer repress MLL target genes. A mutation in CYP339s PPIase domain, leads to an enzymatically inactive CYP33 which can still bind to MLL. Upon overexpression of MLL and CYP33, HDAC is recruited to the MLL complex, as demonstrated by co-immunopreciptiation. However, when the CYP33 PPIase mutant is overexpressed, the lack of PPIase activity prevents the recruitment of HDAC to MLL. As a consequence the chromatin retains the acetylation mark on histone H3 and, although the CYP33 PPIase mutant binds MLL, no repression of MLL target genes is observed. Conversely, upon knockdown of wild-type CYP33, MLL target gene expression and H3K27Ac are increased. This study aids in the understanding of how MLL and CYP33 modulate gene function and helps to identify some of the mechanisms involved in hematopoietic development and leukemia.

What drives opposition to high-voltage transmission lines?

This paper critically reviews theoretical and empirical research from planning, social psychology, and political science relevant to the siting of high-voltage transmission lines (HVTLs). Siting of new HVTLs is important to reducing the emissions of greenhouse gases from the electricity sector as well as meeting demands for reliable power. We synthesize existing research by developing a meso-level framework that integrates and extends existing individual-level theories to better account for the nested impact of social interactions and institutional variables on siting outcomes. We apply our framework to a HVTL case in California where community based opposition was effective due to the perceived high risk of the project and where trust in institutions was low. Statutory p for using existing right-of-ways, land use attributes, and political lobbying were also important in explaining the HVTL siting outcome.
A format language

One of the most primitive parts of a formula language is its specification of input-output actions within the framework of the language. While the specification is intrinsically more complex, say, than the evaluation of an arithmetic expression, most of the difficulties associated with input-output specification arise from the fact that the desired operations have not been properly defined using the framework of a programming language. Indeed, the complexity largely disappears when a programming language is constructed to specify input-output actions. The point to be made here is that the definition of an appropriate programming language makes more rational and simpler all three phases of the input-output programming cycle: (i) source program construction, (ii) object program construction, (iii) object program execution.
A cure for crime: Can mental health treatment diversion reduce crime among youth?

Youth crime is a serious social problem, as is the high proportion of young offenders in the juvenile justice system who have mental disorders. A recent policy innovation applies the theory of therapeutic jurisprudence and diverts youth with mental disorders to treatment in lieu of further court processing. The expansion of mental health diversion programs reflects an increasingly popular view that there is a causal relationship between youth mental disorders and crime. Policymakers who share this view place greater emphasis on rehabilitation and treatment as a way to reduce crime, rather than on stricter punishment. This paper considers the policy issues around youth mental health diversion programs. In addition, it evaluates the effect of a mental health diversion program for youth that was implemented in Texas. The paper finds that mental health diversion can be used effectively to delay or prevent youth recidivism.
Proton Distributions in High-Energy Proton-Proton Collisions

The spectrum of protons in proton-proton collisions is analyzed in terms of a fragmentation model. Particular attention is devoted to the strength of the isobar production and the energy dependence of the background. The model reproduces the shape and energy dependence of the proton spectrum in a very detailed way. Some problems of identifying production mechanisms from these data are discussed.

RABBIT POX : II. PATHOLOGY OF THE EPIDEMIC DISEASE.

The lesions found in animals with epidemic rabbit pox have been described in this paper. The most distinctive gross lesion in all organs and tissues was the small nodule or papule which was found to consist of mononuclear infiltration and necrosis. Diffuse lesions were also found in which the infiltration was widespread and accompanied by edema, hemorrhage and extensive necrosis of affected tissues and organs. The possibility of the diffuse lesions being due to the action of secondary invaders was considered, but available evidence indicated that the different types, including pneumonia, represented reactions to a single causative agent. Moreover, an intimate relationship was observed to exist between lesions and small blood vessels in which primary endothelial damage was usually apparent. The degree of vascular damage generally corresponded to the extent of the lesion and it is probable that this in turn corresponded to the dose of the causative agent. The close analogy between the clinical manifestations and pathological processes of this disease in the rabbit and small pox in man led to the conclusion that the disease in the rabbit is essentially the same as small pox, and that it is probably produced by a virus closely related to the virus of small pox. Available evidence indicated that the infection originated in the Institute and that it spread in atypical form or masked by some other disease until it reached the breeding colony as a clearly defined epidemic infection.

DIAGNOSTIC SPECIFICITY AND POSSIBLE PATHOGENETIC SIGNIFICANCE OF INCLUSIONS IN SYNOVIAL LEUCOCYTES.

Synovial fluid leucocytes from 70 patients with rheumatoid arthritis contained cytoplasmic inclusions; homogenates of these cells gave positive tests for rheumatoid factor in 66 (94 per cent), including 15 who had no demonstrable rheumatoid factor in serum or synovial fluid. Similar inclusions were seen in 14 of 71 patients with other rheumatic diseases, but only 3 (4 per cent) gave positive tests for rheumatoid factor. The inclusions apparently consisted of phagocytized precipitates containing rheumatoid factor; in vitro phagocytosis of rheumatoid factor-fraction II precipitates activated lysosomal enzymes.

SALTINE CRACKER FLAVOR: PREPARING A MIXTURE TO ENHANCE CRACKER FLAVOR

The amount of free amino and organic acids produced in 25-hour fermentation were measured. A mixture to enhance cracker flavor was prepared. The mixture was added to a short-time saltine cracker formula (2 hr fermentation). Sensory evaluation showed that the mixture fully duplicates flavor and aroma for 25 hr fermentation.
Theoretical Predictions For Continuous Slurry Feeding of a Glass Melter

Radioactive defense waste currently stored at the Savannah River Plant in liquid form is to be immobilized by incorporation into a borosilicate glass. The glass melter for this process will consist of a refractory lined tank enclosed in a water-cooled, steel vessel and fed by an aqueous slurry of glass frit plus radioactive waste. As an aid to understanding the melting process and scaling data from small melters, conservation principles were used to develop equations for predicting the melt rate for a feedpile of arbitrary radius plus additional information regarding feedpile behavior and energy consumption.
Self-evaluations of antidepressants.

Antidepressant clinical drug trials conducted from 1955–1972 are analyzed to determine the most frequently used patient self-rating scales and to estimate their relative sensitivities (validities). Other analyses suggest how the methodology of the trials may have influenced measurement sensitivity. Interpretive problems are discussed, and some tentative recommendations are presented.
Microstructure and magnetic properties of zone melt textured YBa2Cu3O6+x with BaSnO3 additions

Abstract The effect of BaSnO3 additions on the microstructure and magnetic properties of zone melt textured YBa2Cu3O6+x (YBCO) wires has been investigated. BaSnO3 additions improve the magnetization properties over similarly textured YBCO wires in low fields, but do not show a noticeable improvement at higher fields (> 2 T). Microstructural effects of BaSnO3 include a reduction in size of 211 precipitates and a decrease in the YBCO platelet width. Magnetic critical current densities (Jc) in excess of 8 × 104 A/cm2 in zero field, and 2.0 × 104 A/cm2 at 1 T are observed. The improvement in low field properties are observed to peak at a YBCO:BaSnO3 molar ratio of 3:1, and then degrade with additional BaSnO3 additions.

Low take-off angle XPS of oxidic planar model NiWγ-Al2)O3 catalysts

Abstract Low take-off angle X-ray photoelectron spectroscopy (XPS) was used to study planar models of the oxidic form of the NiW γ- Al 2 O 3 hydrotreating system. Planar alumina films, grown anodically, were sequentially impregnated with solutions containing tungsten and nickel, and then calcined at 200, 350, and 500 °C. XPS analyses were done using take-off angles of 90, 65, 40, and 10 °. The results from the planar models were compared to XPS results (normal take-off angle) from “real” or powdered catalysts. The powdered catalysts consisted of powders made by sequential impregnation of γ-alumina and of a commercial NiOWO 3 γ- Al 2 O 3 catalyst, both of which were calcined at 450 and 750 °C. Compositional effects for the models appear to indicate that the addition of a small amount of Ni dramatically increases the surface tungstate species (as evidenced by the W 4f Al 2p ratio at low take-off angles); this is consistent with the powder data in that a small addition of Ni does not decrease the W Al ratio. Calcination effects truly show similar trends in both the planar models and the powdered catalysts. Nickel appears to migrate into the support at the highest calcination temperatures while tungsten is redistributed on the outermost surface. Oxidic planar models that show quite similar surface spectroscopic characteristics and similar surface chemistry to real hydrotreating catalysts can be feasibly prepared.
Observation of line shifts and line profiles in an inductively coupled argon plasma

Abstract Shifts in spectral line positions of argon, iron, barium, calcium and strontium are addressed in this preliminary study of the effect of pressure, and electron density on wavenumber position in the 27.12 MHz inductively coupled plasma (ICP). We report line shifts for three sets of data in an argon ICP. The first set of data shows the effect of power (1.1, 1.5, 1.9 kW) on shifts of argon (21 lines) and iron (28 lines) lines in the ultraviolet and visible. The second set of data gives shifts of 25 Ar lines in the near infrared (i.r.) and far visible at 1.1 kW. The third set of data concerns prominent ion lines of calcium, barium and strontium. Commercial hollow cathode lamps (HCL) were used to obtain unshifted line positions. The Los Alamos Fourier Transform Spectrometer was used to obtain the data.
Head lice infestation: single drug versus combination therapy.

To the Editor — Hipolito et al1 reported their interesting observations on the efficacy of 3 treatments for head louse infestations (HLIs), and made specific recommendations for combined treatment with 1% permethrin and trimethoprim/sulfamethoxazole (TMP/SMX). Several problems are evident in their methodology and interpretation, however, and their choice of therapy may be inappropriate. The diagnostic criteria the authors used for HLIs included the presence of lice (adults or nymphs) …
Comparing evaporative sources of terrestrial precipitation and their extremes in MERRA using relative entropy

AbstractA quasi-isentropic, back-trajectory scheme is applied to output from the Modern-Era Retrospective Analysis for Research and Applications (MERRA) and a land-only replay with corrected precipitation to estimate surface evaporative sources of moisture supplying precipitation over every ice-free land location for the period 1979–2005. The evaporative source patterns for any location and time period are effectively two-dimensional probability distributions. As such, the evaporative sources for extreme situations like droughts or wet intervals can be compared to the corresponding climatological distributions using the method of relative entropy. Significant differences are found to be common and widespread for droughts, but not wet periods, when monthly data are examined.

Management of Conventional Mass Casualty Incidents: Ten Commandments for Hospital Planning

The successful management of mass casualty incidents (MCIs) requires standardization of planning, training, and deployment of response. Recent events in the United States, most importantly the Hurricane season in 2005, demonstrated a lack of a unified response plan at local, regional, state, and federal levels. A standard Israeli protocol for hospital preparedness for conventional MCIs, produced by the Office of Emergency Preparedness of the Israeli Ministry of Health, has been reviewed, modified, adapted, and tested in both drills and actual events at a large university medical center in the United States. Lessons learned from this process are herein presented as the10 most important steps (ie, Commandments) to follow when preparing hospitals to be able to respond to conventional MCIs. The standard Israeli emergency protocols have proved to be universally adaptable, flexible, and designed to be adapted by any healthcare institution, regardless of its size and location.
PIECEWISE-CONSTANT MAGNITUDE FILTERS USING ALLPASS SECTIONS.

A new configuration of allpass filters is proposed for designing multiband filters which approximate a piecewise-constant magnitude response. A procedure for deriving the individual allpass building blocks from elliptic filters is presented. A numerical procedure for approximating an equiripple response is also described.
Adrenergic responsiveness in vitro of iris dilator muscle from rabbits with experimentally induced thyroid disorders

Abstract The in vitro adrenergic responsiveness of iris dilator muscles from control, hypothyroid, and hyperthyroid rabbits was determined. Hypothyroidism was induced by surgical removal of the thyroid gland and hyperthyroidism was induced by injection of thyroxine. Dose-response relationships were determined for norepinephrine (an alpha adrenergic agonist) and isoproterenol (a beta adrenergic agonist). ED 50 values indicate increases in the affinity of α and β receptors in both thyroid disorders. Differences in the maximum responses of tissues to the adrenergic agonists may indicate changes in the populations of receptors, i.e. increased density of α receptors in hypothyroid tissues and decreased density in hyperthyroidism with no statistically significant changes in β receptors.

Defining and satisfying the computing requirements of the EOS scientific computing facilities at NASA/MSFC

The computing requirements of the individual scientific computing facilities (SCFs) have been evaluated. The requirements under consideration include CPU-intensive vector and scalar processing, visualization, data storage, connectivity, and I/O peripherals. A hierarchy consisting of shared and individual resources is proposed to most effectively meet the total SCF computing requirements. This hierarchy includes a supercomputer class vector processor; a high-end scalar multiprocessor workstation; a high-speed, large capacity file server; a few medium to high-end visualization workstations; and low to medium range personal graphics workstations.
Purification and in vitro activities of the Bacillus subtilis TnrA transcription factor.

Abstract The Bacillus subtilis nitrogen regulatory protein TnrA was purified and its interaction with the nrgAB regulatory region examined. The TnrA protein activates transcription from the nrgAB promoter in vitro . DNase I footprinting and methylation protection experiments demonstrated that TnrA binds to an inverted repeat, upstream of the −35 region of the nrgAB promoter. Gel mobility retardation assays were used to determine the affinity of TnrA for its DNA-binding site. The equilibrium dissociation binding constant for the interaction of TnrA with the nrgAB promoter fragment was 7.7 nM under the conditions used here. Mutations in the TnrA consensus sequence that reduce nrgAB expression in vivo were found to reduce significantly the in vitro affinity for TnrA. An A + T rich region located upstream of the TnrA-binding site was found to be necessary for optimal transcriptional activation. A mutant protein, TnrA HTH , was constructed in which the putative helix-turn-helix DNA-binding motif was altered by exchanging two arginine residues for alanine residues. The TnrA HTH protein was unable to activate the in vivo expression of nrgAB and had an in vitro affinity for the nrgAB promoter that was significantly lower than that of the wild-type protein.
Platelet-activating factor acetylhydrolase: is it good or bad for you?

Purpose of review Although findings obtained from various studies are inconclusive in determining whether plasma platelet-activating factor acetylhydrolase, or lipoprotein-associated phospholipase A2, plays a proatherogenic or antiatherogenic role in atherosclerosis, many recent reviews appear to favor it as a risk factor for coronary artery disease. To provide a contrasting view, this review focuses on the enzyme's antiatherogenic and antiinflammatory properties. Recent findings A recent report demonstrates that plasma platelet-activating factor acetylhydrolase activity increases in men and women with stable angina or acute coronary syndromes, supporting previously published data that plasma levels of the protein are independently and positively associated with the risk of coronary artery disease. In contrast, at least four lines of evidence indicate that the enzyme has strong antiatherogenic properties: (1) it inhibits the effects of LDL oxidation, (2) genetic deficiency of plasma levels constitutes a risk factor for vascular diseases including atherosclerosis, (3) adenoviral transfer of the protein reduces atherosclerosis in apolipoprotein E-deficient mice, and (4) pretreatment of an electronegative LDL subfraction isolated from hypercholesterolemic human plasma with a recombinant platelet-activating factor acetylhydrolase completely abolishes the proapoptotic effects of the electronegative LDL on vascular endothelial cells. Additionally, treatment with the recombinant product reduced mortality from severe sepsis in a phase IIb clinical trial. In an animal study, transfection of tumor cells with platelet-activating factor acetylhydrolase inhibited tumor growth at the site of implantation. Summary Plasma platelet-activating factor acetylhydrolase becomes progressively activated as atherosclerosis progresses, but lines of evidence indicate that the enzyme possesses potent antiatherogenic and antiinflammatory properties. This raises the question of whether increased activity is a cause or a result of atherosclerosis and, consequently, whether inhibiting the enzyme's activities may decelerate or accelerate the progress of the disease.
Exploration of global oceanic ridge system unfolds

Less than 10% of the global mid-ocean ridge system has been studied in detail. To remedy this problem, a program called Ridge Interdisciplinary Global Experiments (RIDGE) is integrating observational, experimental, and theoretical studies into a decade-long effort to understand the geological, geochemical, and biological processes responsible for creating new oceanic crust along this system of ridges on the ocean floor. RIDGE tackles many scientific fronts simultaneously—since the first field program went to sea in 1991, more than 60 field programs, experimental and laboratory investigations, and theoretical studies involving over 70 investigators have been supported.
Should Proton Pump Inhibitors Be Withheld From Patients Taking Clopidogrel? The Issue That Has Been Giving Me Heartburn!

Both the Food and Drug Administration in the USA and the European Medicines Agency, have published warnings against the coadministration of clopidogrel with proton pump inhibitors (PPIs). Accordingly, many patients attempting to fill prescriptions for a PPI and clopidogrel (or even worse, a PPI with clopidogrel and aspirin, or with clopidogrel, aspirin, and an anticoagulant) are warned by pharmacists and often by providers not to take them together. Accordingly, some patients have delayed initiating the PPI and others the clopidogrel until they spoke with their physician and have experienced stent thrombosis and worse as a result. It is timely, therefore, that a talented group of investigators from Duke would study the quality of the evidence supporting the existence of a clinically relevant interaction between PPIs and clopidogrel, reported in this issue of Circulation: Cardiovascular Quality and Outcomes .1 Briefly, the investigators found that all randomized trials (they included 4 in their analysis) examining the issue suggest that no clinically detectable interaction exists, but that most of the 36 observational studies they analyzed suggest that an interaction does exist that patients on clopidogrel and a PPI have more thrombotic events that those taking clopidogrel without a PPI. The authors conclude that unmeasured confounders in the observational studies are the likely explanation of the discordant findings between randomized control trials and observational studies, and call for more studies examining the issue.

Calculations on ground and excited state potential energy surfaces of floppy free radicals: HC4H2, HC3NH, and HC3O

Abstract Ab initio calculations using the 6-311G(d, p) basis set at the QCISD and CCSD(T) levels were undertaken on the ground and lowest excited electronic states of the isoelectronic carbon-chain free radicals, HC4H2, HC3NH and HC3O. The equilibrium geometry for each molecule is a Cs structure with four electrons in a″ orbitals, and the lowest excited states are characterized by configurations with three, five, and six a″ electrons. The effective vibrational potential energy surfaces of these states along the two lowest frequency in-plane bending coordinates were investigated in order to assess the trend in large-amplitude motions and isomerization across different electronic configurations in a series of isoelectronic molecules. The (4-a″) ground state potential surfaces of HC3NH and HC3O are subject to the Renner-Teller effect, and intersect the (5-a″) excited state surfaces at linear 2π states of at 2300 cm−1 and 8400 cm−1, respectively, above the energy of the equilibrium geometries. The (3-a″) states of HC3O and HC3NH lie 27 000 cm−1 and 24 000 cm−1 above the (4-a″) equilibrium states, respectively, and form Renner-Teller pairs with the (6-a″) tates. Although two minima are found for HC3O and HC3NH on the (3-a″) surface, none of these minima is stable with respect to planarity. The (5-a″) surface of HC4H2 has a single minimum at a C2v structure, which is unstable with respect to the ground state. The (3-a″) surface has two minima, both of which are stable. Equilibrium structures, excitation energies, and potential surface properties for these structures are reported.
