Citando Mario Juruna: imaginário linguístico e a transformação da voz indígena na imprensa brasileira

No presente artigo, revelo os mecanismos textuais que influentes editores de noticias empregaram para manipular a compreensao popular acerca de Mario Juruna, lider xavante que desempenhou um papel importante no avanco da democracia durante a ditadura militar brasileira e se tornou o primeiro indigena eleito para o Congresso Nacional. Argumento que os editores usaram as mensagens implicitas da representacao da linguagem para encetar mudancas na percepcao do publico a respeito do lider xavante, mudando, com isso, a opiniao a seu respeito. O caso Juruna evidencia que os recursos linguisticos sao ferramentas poderosas que instituicoes hegemonicas, como a imprensa e outros grupos dominantes, podem empregar para promover seus proprios interesses, influenciando a opiniao publica em questoes de importância politica e social.
Classical conditioning of heart rate and blood pressure in Macaca mulatta

Classical delay conditioning of heart rate, and of systolic and diastolic blood pressures, was carried out in 16 rhesus monkeys. Blood pressure and inter-systolic interval were measured from an in-dwelling arterial catheter; recordings were taken prior to conditioned stimulus (CS) on each trial, during a 20 sec visual stimulus that filled the conditioned-unconditioned stimulus (CS-UCS) interval, and following UCS (a brief electric tail-shock). The heart rate response both to CS and to UCS was biphasic (acceleration followed by deceleration); the blood pressure response functions were more complex, and were different for the CS and post-UCS periods. Comparison of the patterns of cardiac and blood pressure responses on any trial indicates a possible sequence of baroreceptor reflex activity.
Relation of the stacking fault energy to segregation at stacking faults and to the occurrence of phase boundaries in f.c.c. binary alloys

Abstract A calculation is made on the segregation of solute atoms at stacking faults in f.c.c. crystals under equilibrium conditions. The expression given by Dorm relating the concentrations of solute atoms in the faulted and unfaulted regions is rederived. A new expression is given for the equilibrium width of the stacking fault in terms of the solute concentration, which can be interpreted in terms of the balance of forces on each partial dislocation. On the assumption that the stacking fault energy is exactly the difference in the free energy of the f.c.c. and h.c.p. structures of the same composition and temperature, it is shown that the f.c.c. and h.c.p. phase boundary concentrations of the alloy may be related to the concentration dependence of the stacking fault energy. A numerical example for a hypothetical alloy illustrates the various aspects of the theory.
The introduction and naturalization of Schinus molle (pepper tree) in Riverside, California

Abstract In the late nineteenth century, an exotic tree from Peru, Schinus molle , was introduced for use in street planting at Riverside, California. Trees have since become naturalized in wildlands surrounding Riverside in areas with persistent moisture and bare soil, including riparian habitats, washes and springs, sites downslope from pavement which amplifies run-off, and irrigated citrus groves. The establishment of S. molle including seed viability and germination, seedling establishment, and phenology was evaluated from historical sources, field observations, and experimental tests in a lath house and the Agricultural Operations plot at the University of California, Riverside. Recruitment and migration of S. molle beyond the urban fringe has been slow, but cumulative because rare establishment is compensated by enduring survival. Phenotypic plasticity enables S. molle to adjust its phenology to a Mediterranean climate. Flowers and fruit develop continuously. Seeds are widely dispersed by birds, mammals, and water. Germination time varies inversely with temperature. Once well established seedling mortality was rare. Growth is greatest in the warm season until soil moisture is depleted. With continuous seed production and reliable dispersal the major bottleneck to establishment appears to be germination and seedling survival. While warm weather germination restricts establishment to occasional late spring and summer rains, it allows seedlings to flourish without competition from winter-active shrubs and grasses. S. molle maintains a continuous seed supply for germination whenever conditions are favorable. Autonomous development, free from interspecific interference, enables more efficient site occupation, allowing S. molle to grow as a tree in a shrubland.
A review of repeat prostate biopsies and the influence of technique on cancer detection: our experience

Background Follow-up of patients with an initial negative prostate biopsy, but surrounding whom a suspicion of prostate cancer persists, is difficult. In addition, debate exists as to the optimal technique for repeat prostate biopsy.
The Decomposition of Trimethylgallium and Trimethylaluminum on Si(100)

The decomposition of trimethylgallium (TMG) and trimethylaluminum (TMA) on Si(100) is studied by TPD, XPS, and EELS. It is found that the decomposition of TMG is largely an intramolecular process. First one of the methyl groups in the TMG reacts with a hydrogen in another methyl group liberating methane. This leaves a CH2 group bound to the gallium which is seen clearly in EELS. Subsequently, another hydrogen reacts with a methyl group producing additional methane. This leaves a gallium atom and a CH group on the surface. Hydrogen desorbs, while carbon is incorporated into the growing film. Careful calibration of the peak areas in the TPD data indicates that 2.1 ± 0.3 moles of methane, 0.5 ± 0.03 moles of hydrogen, 1 mole of gallium, and 0.95 ± 0.1 moles of surface carbon are produced for every mole of TMG which decomposes. Since, the decomposition ratio is independent of the state of the surface, the surface orientation, and the level of impurities on the surface, it appears that the surface is not a direct participant in the reaction. TMA adsorbs as dimers. However, the dimers decompose upon heating to 400 K. Thereafter, the chemistry of TMA decomposition is similar to that for TMG. Nonetheless, the product ratio varies with the TMA coverage, the state of the surface, and the aluminum coverage. Also, silicon-carbon bonds are evident at 600 K in EELS. It is suggested, therefore, that the decomposition of TMA is similar to that of TMG, except that methyl groups in TMA have a tendency to migrate to the support. In both TMA and TMG, carbon incorporation is an intrinsic part of the decomposition process. This suggests that TMA and TMG would not be appropriate source gases when one needs to produce films with very low carbon levels.
773-1 Endovascular Radiation Prior to Stent Implantation Inhibits Neointimal Proliferation in Porcine Coronary Arteries

Stent implantation has been shown to reduce restenosis by establishing a larger lumen not by reducing neointima formation. We have previously shown that ionizing radiation reduced neointima formation in a swine model of restenosis. The purpose of this study was to determine whether endovascular radiation of the coronary artery prior to stent implantation would affect neointima formation. Five normolipemic pigs underwent coronary angiography; segments of the LAD or the CX were chosen as targets for stenting. A high energy 192 lridium source was used to deliver 1400 cGy by random assignment to One of the vessels, then 3.5 mm tantalum stents were implantedin both arteries. All animals received aspirin 325 mg daily. They were killed at 30 days, and the coronary vasculature perfusion fixed with 10% formalin. The arteries were embedded in methyl methacrylate, and sectioned with the stents in place using a low-speed saw. Serial sections spanning the injury site were ground to 30 μm, stained with toluidine blue, then evaluated by histopathologic and morphometric techniques. The maximal intimal thickness (MIT), intimal area (IA), and vessel perimeter (VPI were measured from each section. Student's paired Hest was used for comparison of groups. Stent artery ratio was similar in the radiated artery 1.52 ± 0.55 versus control 1.50 ± 0.33. MIT, mm IA, mm 2 Vp, mm Control 0.9 ± 0.47 3.64 ± 1.52 10.6 ± 1.54 Irradiated 0.63 ± 0.28 2.34 ± 1.48 10.5 ± 0.62 P value 0.03 0.007 0.8 Conclusion Endovascular radiation prior to coronary stenting reduces neointima formation and may reduce further the restenosis rate after stent implantation.
Jet-cooled fluorescence spectra, Raman spectra, and potential energy surfaces of stilbenes

The jet-cooled fluorescence excitation spectra and dispersed fluorescence spectra of trans- stilbene (t-S) and 4-methoxy-trans-stilbene (MS) have been recorded and analyzed. Preliminary results for 4,4'-dimethyl-trans-stilbene have also been obtained. The high- temperature vapor-phase and liquid phase Raman spectra of these molecules along with cis- stilbene have also been recorded. The low-frequency vibrational modes have been assigned, and the vibrational progressions associated with the two phenyl torsions and the ethylinic internal rotation, which primarily governs the photoisomerization process, have been analyzed. For t-S and MS the two-dimensional phenyl torsion potential energy surfaces and the one-dimensional carbon-carbon double bond torsional potential energy functions for both the S0 and S1((pi) , (pi) *) states were determined. The barriers to simultaneous phenyl internal rotation are 3100 cm-1 for the ground state and 3000 cm-1 for the excited state. The data for the C equals C torsion are consistent with a trans yields cis barrier of 48.3 kcal/mole for the S0 state and a trans yields twist barrier of 2000 to 3500 cm-1 for the S1 state. For MS the barrier for simultaneous phenyl torsion for both the S0 and S1 states is 2860 cm-1. The C equals C torsional barrier for MS in both the S0 and S1 states is approximately 10% higher than that of t-S.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.

5-Hydroxytryptamine and transmission in sympathetic ganglia.

Abstract Rat stellate ganglia were isolated and maintained in a moist chamber in which they were intermittently immersed in physiological saline containing low concentrations of the compound under investigation. 5-Hydroxytryptamine (serotonin) in concentrations as low as 1.3×10-6 M reduced reversibly the threshold and increased the amplitude of responses to preganglionic stimulation. Certain antagonists of 5-hydroxytryptamine depressed reversibly the postsynaptic responses. Experiments in vivo supported this finding. It is suggested that 5-hydroxytryptamine facilitates transmission in the sympathetic ganglia of rats.
Subharmonic destruction of generalized chaos synchronization

A bifurcation of transition that destroys generalized chaos synchronization is considered. This transition frequently occurs in regimes of subharmonic chaos entrainment where synchronization can be abruptly terminated due only to an almost unnoticeable change in the shape of the driving attractor. We explore the main cause of this sensitivity and ascertain the mechanism behind this transition.
Taming Multivariate Data: Conceptual and Methodological Issues

Hyperspecificity in visual implicit learning: learning of spatial layout is contingent on item identity.

Humans conduct visual search faster when the same display is presented for a 2nd time, showing implicit learning of repeated displays. This study examines whether learning of a spatial layout transfers to other layouts that are occupied by items of new shapes or colors. The authors show that spatial context learning is sometimes contingent on item identity. For example, when the training session included some trials with black items and other trials with white items, learning of the spatial layout became specific to the trained color—no transfer was seen when items were in a new color during testing. However, when the training session included only trials in black (or white), learning transferred to displays with a new color. Similar results held when items changed shapes after training. The authors conclude that implicit visual learning is sensitive to trial context and that spatial context learning can be identity contingent.
Diagenetic and sedimentological controls on the composition of organic matter preserved in California Borderland Basin sediments

Compound-specific radiocarbon (14C) contents, stable carbon isotopes, and abundances of phytoplankton and vascular plant derived lipid biomarkers (alkenones and fatty acids) were obtained from Santa Barbara Basin and Santa Monica Basin sediments, along with radiocarbon contents of planktic foraminifera and total organic carbon. We investigated core-top and prebomb sediment intervals at sites from the flanks and depocenters of the basins deposited under contrasting bottom water oxygen concentrations. Bulk organic matter generally has the lowest radiocarbon levels of all sediment constituents measured, whereas planktic foraminifera tend to be the most radiocarbon enriched. Alkenones are systematically depleted in radiocarbon with respect to foraminifera. Short-chain (C14 ,C 16 ,C 18) fatty acids decrease rapidly in absolute abundance and relative to longer-chain (.C24) homologues from core-top to prebomb samples. The loss of short-chain fatty acids with depth is associated with 13C depletion of short-chain fatty acids, indicating preferential preservation of terrestrially derived fatty acids. Short-chain fatty acids tend to be more 14C-enriched relative to alkenones in core-top sediments, whereas longerchain homologues are generally the most radiocarbon depleted of the lipids studied here. Less refractory compounds (e.g., short-chain fatty acids) are thus enriched in radiocarbon with respect to more recalcitrant biomarkers (alkenones, long-chain fatty acids). The lower 14C content of more refractory compounds reflects a larger proportion of laterally supplied, preaged material. Greater preservation of labile organic compounds observed at the depocenters than in flank sediments results in the presence of ‘‘younger’’ biomarkers, underlining the important influence of selective degradation of labile compounds on their radiocarbon ages.
Simulated Hydrologic Responses to Climate Variations and Change in the Merced, Carson, and American River Basins, Sierra Nevada, California, 1900–2099

Hydrologic responses of river basins in the Sierra Nevada of California to historical and future climate variations and changes are assessed by simulating daily streamflow and water-balance responses to simulated climate variations over a continuous 200-yr period. The coupled atmosphere-ocean-ice-land Parallel Climate Model provides the simulated climate histories, and existing hydrologic models of the Merced, Carson, and American Rivers are used to simulate the basin responses. The historical simulations yield stationary climate and hydrologic variations through the first part of the 20th century until about 1975 when temperatures begin to warm noticeably and when snowmelt and streamflow peaks begin to occur progressively earlier within the seasonal cycle. A future climate simulated with business-as-usual increases in greenhouse-gas and aerosol radiative forcings continues those recent trends through the 21st century with an attendant +2.5 °C warming and a hastening of snowmelt and streamflow within the seasonal cycle by almost a month. The various projected trends in the business-as-usual simulations become readily visible despite realistic simulated natural climatic and hydrologic variability by about 2025. In contrast to these changes that are mostly associated with streamflow timing, long-term average totals of streamflow and other hydrologic fluxes remain similar to the historical mean in all three simulations. A control simulation in which radiative forcings are held constant at 1995 levels for the 50 years following 1995 yields climate and streamflow timing conditions much like the 1980s and 1990s throughout its duration. The availability of continuous climate-change projection outputs and careful design of initial conditions and control experiments, like those utilized here, promise to improve the quality and usability of future climate-change impact assessments.
Dynamic, multi-core cache coherence architecture for power-sensitive mobile processors

Today, mobile smartphones are expected to be able to run the same complex, memory-intensive applications that were originally designed and coded for general-purpose processors. However, these mobile processors are also expected to be compact, ultra-portable, and provide an always-on, continuous data access paradigm necessitating a low-power design. As mobile processors increasingly begin to leverage multi-core functionality, the power consumption incurred from maintaining coherence between local caches due to bus snooping becomes more prevalent. This paper explores a novel approach to mitigating multi-core processor power consumption in mobile smartphones. By using dynamic application memory behavior, one can intelligently target adjustments in the cache coherency protocol to help reduce the overhead of maintaining consistency when the benefits of multi-core shared cache coherence are muted. On the other hand, by utilizing a fine-grained approach, the proposed architecture can still respond to and enable the benefits of hardware cache coherence in situations where the performance improvements greatly outweigh the associated energy costs. The simulation results show appreciable reductions in overall cache power consumption, with negligible impact to overall execution time.
Screening of Novel Metal Oxide Photocatalysts by Scanning Electrochemical Microscopy and Research of Their Photoelectrochemical Properties

Photocatalyst arrays of a number of metal oxides were prepared by dispensing metal precursor solutions onto fluorine-doped tin oxide-coated glass followed by annealing at 500 °C for 3 h. These were screened by scanning electrochemical microscopy with a scanning optical fiber, and the results showed that all Sn-doped Cd−In−Bi, Zn−In, and W−Cd oxide photocatalysts produced enhanced photocurrents for specific metal ratios. The products of the photoelectrochemical (PEC) reaction could be detected electrochemically by a Au ring on the optical fiber. The PEC properties of larger electrodes were investigated, and the Zn−In and W−Cd oxide photocatalysts showed a much higher photoactivity than Sn-doped Cd−In−Bi. Even without catalysts, they showed visible light response for water oxidation to oxygen.
Potential for travertine formation: Fossil Creek, Arizona

Abstract Chemical analyses of water emanating from Fossil Springs in Central Arizona were conducted to predict changes in travertine deposition related to changes in stream discharge caused by diversion for hydroelectric power generation. During spring of 1996, water was sampled at 15 locations during normal seepage flow in a 6.7 km reach below Fossil Springs and at full baseflow during turbine maintenance. Analyses resulted in a rate of 11,923 kg d−1 of CaCO3 precipitated from 1218 l s−1 of water emanating from the springs, while flows of 5.6 l s−1 that seep past a diversion dam produced 46 kg d−1 of CaCO3 precipitation. Active travertine dams currently occur predominantly below the Irving hydroelectric powerplant with partial return of diverted flow back into the natural channel. The lower reach resulted in 519 kg d−1 of CaCO3 precipitated from the return of 56.6 l s−1 with a reduced rate of precipitation during surface runoff conditions due to a dilution effect. Artificial substrates were located at sites in the lower reach for comparison with mass transfer rates derived from changes in water chemistry. Comparison between actual precipitation rates and overall mass transfer rates suggested preferential deposition was occurring at dam locations. Rates of mass transfer for high flow were greater than lower flow. Overall, mass transfer rates for the upper reach were proportional to the flow velocities with total mass transfers for both flows being approximately equal.
Long survival after ovarian and hepatic metastasis from carcinoma of the large bowel: Report of a case

Herein we present the case of a woman who is now 19 years post abdominoperineal resection for a Dukes' C1 rectal carcinoma, 10 years post right hemicolectomy for a Duke's C1 carcinoma of the ascending colon and removal of a solitary hepatic metastasis and now 9 years post resection of an ovarian metastasis. She had 5-fluoracil, postoperatively. This is the ninth case reported in the literature of a 5-year survivor free of disease following oophorectomy for metastatic adenocarcinoma of the large bowel. The finding of ovarian and hepatic metastases from her colorectal carcinoma would have indicated a poor prognosis. We feel that those rare patients who have an unexpected long survival should be reported for accumulation of clinical data, illustration of their clinical management, and analyses of the applied therapeutic interventions.
Shape sensitive geometric permutations

We prove that a set of n unit balls in Rd admits at most four distinct geometric permutations, or line transversals, thus settling a long-standing conjecture in combinatorial geometry. The constant bound significantly improves upon the T(nd-1) bound for the balls of arbitrary radii. Intrigued by this large gap between the two bounds, we also investigate how the number of geometric permutations varies as a function of shape, size, and spacing of objects. Our results include a tight bound of 2d-1 on the geometric permutations of n disjoint rectangular boxes in Rd, and a constant bound on the geometric permutations for disks in the plane when the ratio between the largest to smallest disks is bounded. An important consequence of the former theorem is that if the smallest bounding boxes containing a set of geometric objects in Rd are pairwise disjoint, then those objects admit only 2d-1 permutations, which is a significant improvement on the O(n2d-2) bound known for general convex objects.
Microbial identification and antibiotic sensitivity testing, an aid for patients refractory to periodontal therapy. A report of 3 cases.

Abstract The importance of microbial surveillance is illustrated in 3 clinical cases. Each case demonstrated a continued lack of response to conventional periodontal treatment. Repeated bouts of periodontal abscess formation and bone Joss occurred over a 3- to 4- year period, despite numerous surgeries supplemented with antibiotics. As a result, patients were termed refractory to treatment and extensive microbiological analysis and sensitivity testing was performed. Following institution of the appropriate antibiotic and conservative therapy consisting of several sessions of scaling and root planing, each of these cases demonstrated a dramatic remission of disease progression. No further breakdown has been seen for a minimum of 21/2, years. While anecdotal in nature, these cases support the usefulness of microbial identification coupled with antibiotic sensitivity as an adjunct to conventional conservative periodontal therapy.
Real-time PCR provides improved detection and titer determination of bacteriophage

The plaque assay is the traditional method for the quantification of bacteriophage, particularly for lambda cloning vectors. Unfortunately, this technique is fraught with procedural difficulties, and the quality of the data obtained from this "gold standard" assay may be inaccurate due to the subjective interpretation of the results. The application of quantitative real-time PCR (QPCR) technology can address these issues and be a more accurate platform to evaluate phage growth conditions and quantify viral titers in phage preparations. QPCR, with an improved primer set specific for lambda phage and coupled with fluorescent dye detection of PCR products, was used to detect and quantify phages in lysates with no prior DNA purification. Phages were detected below one plaque-forming unit, and at least 89 viral copies were detected from a purified DNA sample. When unknown concentrations of various phage preparations were assessed using QPCR, they were attained more efficiently, with greater sensitivity and precision, and the method produced more accurate quantitative data spanning a wider linear range than those obtained by the plaque assay (six logs vs. one log, respectively). Finally, QPCR for the detection of phage has multiple applications, including conventional cloning and in alternative fields of study such as environmental sciences.
Cerebrovascular steal phenomenon in a patient undergoing dipyridamole nuclear perfusion cardiac imaging.

Summary Transient ischemic neurological deficits following intravenous dipyridamole administration during pharmacological cardiac stress test are seldom reported, but there can be serious vascular complications. We report a case of a 58-year-old Caucasian male who developed expressive aphasia after dipyridamole infusion during an elective dipyridamole-technetium cardiac stress test performed for chest pain. Computed tomography angiogram of the neck revealed a known total occlusion of the right internal carotid artery and 50% stenosis of the left internal carotid artery. The patient's aphasia spontaneously resolved within 24 h. In this paper, we report a unique case in which the administration of intravenous dipyridamole precipitated transient ischemic attack in a patient with stable asymptomatic bilateral carotid artery disease and prior carotid endarterectomy. We also discuss the intracerebral vascular steal phenomenon as a possible pathophysiological mechanism in this patient.
Cardiac testing and outcomes in infants after an apparent life-threatening event

Objectives We sought to determine the yield of cardiac testing and to identify predictors of cardiac disease in infants with an apparent life-threatening event (ALTE). Design Retrospective longitudinal cohort study. Setting Paediatric hospital providing primary and tertiary care that is part of an integrated healthcare system. Patients Infants hospitalised for an ALTE from 1999 to 2003. Main exposures Cardiac testing used at time of ALTE and results, and clinical risk factors for cardiac disease. Outcome measures Short-term (during hospitalisation) and long-term (through November 2009) follow-up for any diagnosis of significant cardiac anatomic or rhythm abnormality. Results Study criteria were met by 485 infants (mean age 1.9, SD±2.2 months; 49% boys). Cardiac testing was performed on 219 (45%) patients during ALTE hospitalisation, identifying two patients with significant cardiac disease (cardiomyopathy, ventricular pre-excitation). During 7.7 years of follow-up, three additional significant cardiac diagnoses (ventricular pre-excitation, frequent ventricular ectopy, moderate aortic stenosis) were identified. All cardiac tests had low positive predictive value (PPV). Significant cardiac disease was associated with prematurity (22% vs 80%, p=0.002), but not age, gender, prior ALTE or rescue breaths. Conclusions This longitudinal study of an ALTE cohort revealed significant cardiac disease in
Enhanced isotropic gradient operator

ABSTRACT We present a two‐dimensional (2D) gradient operator that produces more accurate results than known traditional operators such as Ando, Sobel and the so‐called Isotropic operator. We further extend the derivation to three‐dimensional (3D), a powerful feature missing in all conventional operators. We start by constructing a parameterized formula that generically represents all 2D numerical gradient operators. We then solve for the required parameter by equating this numerical gradient with that obtained analytically from a single Fourier harmonic (or, equivalently here, a stationary plane wave). As this parameter is frequency‐ and direction‐dependent (by virtue of the underlying Fourier harmonic), we construe a pragmatic version of it that is independent of these two variables yet capable of significantly reducing the error associated with traditional operators. Extension to 3D is achieved similarly; it requires dealing with two parameters as opposed to only one in the 2D case. Synthetic and real‐data results confirm higher accuracy from this operator than from traditional ones.
New concepts regarding the pathogenesis of amebiasis.

Our understanding of the pathogenesis of amebiasis has progressed significantly since Dr. Braude's description of the major clinical syndromes of amebic liver abscess. His hypothesis that invasive amebic strains must be resistant to complement-mediated lysis has been confirmed. We have also shown that Entamoeba histolytica activates complement by a unique mechanism, i.e., cleavage of C3 by an extracellular cysteine proteinase. Cysteine proteinases are important virulence factors encoded by at least three genes; one gene, acp1, is unique to invasive strains. The amebic cysteine proteinases are homologous to proteinases released by transformed cells and may represent a common mechanism of tissue invasion. The initial division of Entamoeba into invasive E. histolytica and noninvasive Entamoeba dispar by isoenzymes has been supported by genetic differences between amebae. Thus, a model of pathogenesis differentiating between two separate species of Entamoeba best explains the epidemiology, clinical syndromes, and pathology of amebiasis.
Granulocyte-macrophage colony stimulating factor (GM-CSF) and co-culture can affect post-thaw development and apoptosis in cryopreserved embryos.

Purpose: The objective of this study was to evaluate the effects of growth factor supplementation and Vero cell co-culture on apoptosis and development of frozen thawed one-cell mouse embryos. Methods: The following treatment regimens were assessed: (a) control medium (b) Vero cell co-culture and (c) growth factor supplemented medium. The individual growth factors tested were: GM-CSF, IGF-I, IGF-II, TNF-α, FGF-4, LIF, TGF-α, TGF-β, IL-6, PDGF and EGF. Blastocyst development and differentiation were monitored. At termination of the experiments, overall blastomere number and apoptosis were assessed using the TUNEL assay. Results: No differences were observed in blastulation and hatching rates. ICM differentiation in thawed embryos was notably improved with either co-culture or growth factor supplementation. The only growth factor significantly modulating apoptosis in thawed embryos was granulocyte-macrophage colony stimulating factor (GM-CSF). GM-CSF enhanced continued cell survival and prevented apoptosis but did not influence overall cell number in developing blastocysts. Vero cell co-culture significantly increased cell number in blastocysts (124±42 vs 100±44 in control; P<0.05). Embryonic apoptosis was higher in the co-cultured embryos. The increased presence of apoptotic cells in blastocysts of high cell number may reflect the regulatory role of apoptosis in balancing ICM: TE ratios. Conclusion: These data indicate that culture conditions can modulate post-thaw embryonic development and apoptosis.
On the stress-strain relation for skin

Abstract A simple model of the collagen fiber network in the dermis is used to calculate the strain level at which the stiffness of skin abruptly increases. The calculated critical strain level (57%) agrees roughly with experimental values. It is suggested that entry into the high-modulus region of the stress-strain curve of skin is simply a geometric effect, corresponding to thorough alignment, along the stress direction, of the fibers in the collagen network. The model finds use in systematizing data on the effect of age on the long-range extensibility of skin and on the morphological basis of skin extensibility along and across Langer's lines.
Idealized Numerical Simulations of Hurricane–Trough Interaction

Abstract A three-dimensional, nonhydrostatic, fine-resolution model, with explicitly resolved convective processes, is used to investigate the evolution of (a) a hurricane in two sheared flows, and (b) a hurricane interacting with four different upper-level lows. The negative impact of vertical shear on hurricane intensification is confirmed. The hurricanes display asymmetries that are most pronounced in higher shear flow. In both shear cases, the hurricane asymmetries seem to be related to a single upper-tropospheric outflow jet forcing convective activity below its right entrance region. Weak subsidence is confined to only part of the eye. Less eye subsidence leads to less inner-core warming, and hence a smaller fall in central surface pressure. A hurricane in zero flow (control) displays subsidence in the entire eye leading to a symmetric storm with a deep, strong warm core temperature anomaly and lower central surface pressure. In the weak shear and control cases, the radius of maximum wind (RMW) cont...
CMOS-MEMS resonant RF mixer-filters

An integrated CMOS-MEMS micromechanical resonant mixer-filter with potential for application in a single chip receiver is introduced. Air and anchor damping characterization show quality factor greater than 1500. Downconversion and filtering of signal frequencies as high as 3.2 GHz is achieved. This is the highest signal frequency applied so far to MEMS mixer-filters. Analytical calculations match well with the experimental measurements and are used to show that 0 dB mixer conversion loss is achievable. Co-simulation of the MEMS mixer with readout electronics identifies potential solutions to eliminate mixing feedthrough.
X-ray Diagnostics for Cavitating Nozzle Flow

Cavitation plays a critical role in the internal flow of nozzles such as those used in direct fuel injection systems. However, quantifying the vapor fraction in the nozzle is difficult. The gas-liquid interfaces refract and multiply scatter visible light, making quantitative extinction measurements difficult. X-rays offer a solution to this problem, as they refract and scatter only weakly. In this paper, we report on current progress in the development of several x-ray diagnostics for cavitating nozzle flows. X-ray radiography experiments undertaken at the Advanced Photon Source at Argonne National Laboratory have provided measurements of total projected void fraction in a 500 μm submerged nozzle, which have been directly compared with numerical simulations. From this work, it has been shown that dissolved gases in the liquid also result in the formation of vapor regions, and it is difficult to separate these multiple phenomena. To address this problem, the liquid was doped with an x-ray fluorescent bromine tracer, and the dissolved air substituted with krypton. The fluorescent emission of Br and Kr at x-ray wavelengths provide a novel measurement of both the total void fraction and the dissolved gas component, allowing both cavitation and dissolved gas contributions to be measured independently.

P-005 After MR Selection, Final Infarct Volume is Independent of Time to Thrombectomy for Anterior Large Vessel Occlusion Stroke

Purpose With thrombectomy for anterior circulation large vessel occlusion (ACLVO) stroke, time to recanalization is considered important, but collateral status may be a greater driver of outcome than time. We tested the hypothesis that patients with ACLVO stroke who present with a small core infarct on DWI would show similar good outcomes after thrombectomy, regardless of time from onset. Materials and methods A cohort of 49 patients treated with thrombectomy after MR selection for ACLVO stroke from 11/1/2012 until 5/15/2015 was retrospectively reviewed. Patients were selected for thrombectomy based on DWI screening with presentation core volume ≤100 age considered favorable. Patients were divided into early (n = 24) or extended (n = 25) treatment groups, with intention to treat ≤6 hours = early, and comparisons made with final infarct volume the primary outcome. Results Baseline characteristics were similar (early versus extended), including admission NIHSSS (IQR 13–19 versus 11–18). Recanalization ≥ TICI2B was 79% and 83% respectively. There was no significant difference in median final infarct volume (16 mL versus 22 mL, estimated difference +4 mL [95 CI: –13 – +19], p = 0.61) or median infarct growth (1 mL versus 5 mL, estimated difference 1.0 mL [95 CI: –7.0 – +10], p = 0.71). For decision to treat up to 20 hours after onset, time did not correlate with final infarct volume, Figure 1. Similar rates of complications and mortality were observed. Conclusion Using MR selection, similar good outcomes after thrombectomy for ACLVO stroke may be achieved well beyond 6 hours. Disclosures B. Cristiano: None. M. Pond: None. S. Basu: None. U.

Reproductive Experience may Positively Adjust the Trajectory of Senescence

Although aging is inexorable, aging well is not. From the perspective of research in rats and complementary models, reproductive experience has significant effects; indeed, benefits, which include better-than-average cognitive skills, a slowing of the slope of decline, and a healthier brain and/or nervous system well later into life. Work from our lab and others has suggested that the events of pregnancy and parturition, collectively referred to as reproductive experience—an amalgam of hormone exposure, sensory stimulation, and offspring behavioral experience and interaction—may summate to flatten the degree of decline normally associated with aging. Mimicking the effects of an enriched environment, reproductive experience has been shown to: enhance/protect cognition and decrease anxiety well out to two-plus years; result in fewer hippocampal deposits of the Alzheimer’s disease herald, amyloid precursor protein (APP); and, in general, lead to a healthier biology. Based on a suite of recent work in organisms as diverse as nematodes, flies, and mammals, the ubiquitous hormone insulin and its large family of related substances and receptors may play a major role in mediating some of the effects of RE on the parameters of aging studied thus far. We will discuss the current set of data that suggest mechanisms for successful biological and neurobiological aging, and the implications for understanding aging and senescence in their broadest terms.
Cyber-Physical Fingerprinting for Internet of Things Authentication: Demo Abstract

Current security and privacy solutions fail to meet the IoT requirements due to computational restrictions and portable nature of IoT objects. In this demo, a novel authentication framework is proposed that exploits the device-specific information to authenticate each object in the IoT. The framework is shown to effectively track the physical environment effects on objects. The experiment shows a sample IoT environment consisting of multiple Raspberry PI units operating as IoT objects. The proposed framework monitors the changes of the physical environment surrounding objects by examining the changes in the device-specific information of each IoT object. The scenario of an emulation attacker is presented in the demo as a case study. The attacker is capable of replicating all the transmitted messages and security keys of one of the IoT objects. Our proposed framework is able to effectively detect such an attack and improve the authentication accuracy for all IoT objects. -Demo Abstract.
Effective potential at three loops

The first complete three-loop calculation of the effective potential for a general renormalizable theory is presented. Detailed calculations of the effective potential inform our knowledge of vacuum structure and symmetry breaking in the Standard Model and beyond.
Simulated Neural Dynamics Produces Adaptive Stepping and Stable Transitions in a Robotic Leg

Animals exhibit flexible and adaptive behavior. They can change between modes of locomotion or modify the details of a step to better suit their environment. Insects have massively distributed control architectures in which each joint has its own central pattern generator (CPG), which is coordinated with its neighbors only through sensory information. Different modes of walking (forward, turning, etc.) can be produced by changing which CPGs are affected by which sensory information, called a reflex reversal. The presented robotic leg is controlled by a computational neuroscience model of part of the nervous system of the cockroach Blaberus discoidalis. It steps adaptively to correct for unexpected obstacles and can reverse reflexes to produce turning motions.
Chapter 15 Trends in Neural Modeling for Reach to Grasp

Summary The large variety of models of limb movement control reflect the diverse fields of researchers. Mechanical engineers and roboticists solve the engineering problems of kinematics, dynamics, and impedance control. Neural network researchers address problems in internal representation, learning, and execution of motor patterns. Researchers in computational neuroscience marry motor control functionality with neural anatomy and physiology. Here, we first review the use of optimality criteria to characterize point-to-point reaching movements in terms of the trajectory of the limb endpoint or joint angles. We then turn to behavioral studies which reveal internal motor representations. We look at neural network models: both artificial networks which generate trajectories using either supervised or reinforcement learning, and models of brain regions which control reach and grasp. Finally, we return to the behavioral level to model several phenomena, including perturbed reach, the speed/accuracy trade-off in reaching movements, and the coordination of reach and grasp.
Sartre аnd America

The article is devoted to the North American Sartre Society, which was founded in 1985. The author as its co-founder develops his point of view presenting during panel discussion of Sartre’s relations with the United States on the 2015 meeting. He devoted a lot of papers and books to Sartre’s philosophy. Some of them are presented in the references. The author reflects at a somewhat deeper level on Sartre’s attitudes towards USA in the context of its history and international relations, saying about philosopher’s contradictions, the strategy and tactics of his self-disinvitation. The author traces Sartre’s transition from one myth of America to another in later life. Sartre’s initial experiential encounter with the American reality was by no means entirely positive, but he did like New York City, feeling a sense of freedom in the midst of its crowds that he retained as an important part of his picture of America when back in France. Freedom, an open future, almost unlimited possibilities, and a lack of a sense of history of the sort by which Europe is shackled. Several events of the postwar world history such as Korean war, then Vietnam war paved the way for Sartre’s most salient later attitudes towards America. Meanwhile, Sartre had accepted an invitation to present lectures at Cornell University in 1965. But after American massive bombing of North Vietnam in 1965 Sartre responded by disinviting himself from Cornell by way of protest. Recounting these events, the author of the paper recalls so-called “Cornell Lectures”, which were saved in unfinished manuscript form and have been given the title “Morale et Histoire”. A serious interest in American political life is shown on Sartre’s and Beauvoir’s visit to Cuba as guests of Fidel Castro and Sartre’s participation in Lord Bertrand Russell’s independent War Crimes Tribunal.
Radiation Exposure to Personnel Obtaining Equine Appendicular Radiographs Using a Handheld Generator

Abstract Knowledge of radiation exposure in equine radiography is very limited. A study evaluating operator exposure confirmed the benefits of shielding, but exposure to personnel holding cassettes was not evaluated. This is an analytic study with the objective to measure and compare radiation exposures to personnel using a handheld generator with and without lead shielding. A cadaveric hindlimb was suspended to mimic standing position. Two dosimeters were placed at each of six locations from the generator and cassette to mimic locations of hands, trunk, and thyroid of personnel. At each location, one dosimeter was unshielded and the other was shielded. Six anatomic projections were performed, including lateromedial projections of the foot, metatarsophalangeal joint, tarsus, and stifle, as well as caudolateral–craniomedial oblique and caudocranial stifle projections. Comparisons between radiographer versus cassette holder exposure values were compared using the Wilcoxon signed rank test. Exposure was significantly (P
