Cómo se explica el triunfo de Donald Trump (2016)

Donald Trump ha ganado las elecciones en Estados Unidos contra todo pronostico. Lo ha hecho con un discurso populista dirigido al trabajador blanco y varon norteamericano, que despresia la inmigracion. Trump es un personaje misogino que apela a los mas bajos instintos egoistas de la sociedad estadounidense. Ha ganado haciendo promesas inquietantes, que de llevarlas a cabo podrian hacer de los Estados Unidos de Emerica un pais proteccionista, en un panorama internacional incierto y peligroso. Temas aborda este debate contando con las opiniones de destacados analistas del panorama nacinal e internacional.
Implications of the Eighth Joint National Committee Guidelines for the Management of High Blood Pressure for Aging Adults (2015)

The recent 2014 Evidence-Based Guideline for the Management of High Blood Pressure in Adults from the Eight Joint National Committee Panel may significantly affect the aging US population. We performed a cross-sectional analysis of black and white participants in Atherosclerosis Risk in Communities who participated in the fifth study visit (2011-2013). Sitting blood pressure was calculated from the average of 3 successive readings taken after a 5-minute rest. Currently, prescribed antihypertensive medications were recorded by reviewing medication containers brought to the visit. Blood pressure control was defined using both the Seventh and Eighth Joint National Committee thresholds. Of 6088 participants (mean age, 75.6 [range, 66-90] years, 58.4% women; 23.2% black), 54.9% had either diabetes mellitus or chronic kidney disease. The prevalence of hypertension according to Seventh Joint National Committee thresholds was 81.9%, and 62.8% of the entire sample were at blood pressure goal. Using the Eighth Joint National Committee thresholds, 79.4% were at blood pressure goal (16.6% were reclassified as at-goal). Reclassification was higher for individuals with diabetes mellitus or chronic kidney disease (20.6%) when compared with individuals without either condition (11.6%). The use of antihypertensive medications in our cohort was high, with 75.0% prescribed at least 1 antihypertensive medication and 46.7% on ≥2 antihypertensive agents. In conclusion, in a US cohort of aging white and black individuals, ≈1 in 6 individuals were reclassified as having blood pressure at goal by Eighth Joint National Committee guidelines. Despite these less aggressive goals, >20% remain uncontrolled by the new criteria.
Reducing interprocess communication overhead through register windows (2002)

Inter-process communication (IPC) by message passing is a common paradigm of many operating system architectures. IPC performance is a critical part of overall system performance. Unfortunately, most architectures exhibit extremely high overhead for short communication. We present a combination of hardware and software primitives that effectively eliminate overhead in short message transfers. CPU registers act as a natural interface between task address spaces, making IPC more efficient and easier to implement than existing software solutions. Our performance study shows that using dynamically relocatable register windows can improve overall system performance by more than fifty percent over typical modern system architectures.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
An efficient meta-lock for implementing ubiquitous synchronization (1999)

Programs written in concurrent object-oriented languages, especially ones that employ thread-safe reusable class libraries, can execute synchronization operations (lock, notify, etc.) at an amazing rate. Unless implemented with utmost care, synchronization can become a performance bottleneck. Furthermore, in languages where every object may have its own monitor, per-object space overhead must be minimized. To address these concerns, we have developed a meta-lock to mediate access to synchronization data. The meta-lock is fast (lock + unlock executes in 11 SPARC™ architecture instructions), compact (uses only two bits of space), robust under contention (no busy-waiting), and flexible (supports a variety of higher-level synchronization operations). We have validated the meta-lock with an implementation of the synchronization operations in a high-performance product-quality Java™ virtual machine and report performance data for several large programs.
Transcriptomic signatures of SARS-CoV-2 and Influenza virus infections (2021)

Blood gene-expression was measured in 103 patients infected with SARS-CoV-2 (collectively named “COVID-19”) and compared to that of 22 patients infected with Influenza A or B (INFL) as well as 27 non-infected, healthy individuals (HLTY) COVID-19 patients were stratified according to the level of respiratory failure; 23 did not require oxygen support (“OXY0”), 40 received oxygen but no mechanical ventilation (“OXY1”) and 40 required mechanical ventilation (“TUBE”). In the latter group, 15 patients were sampled within the first 7 days in hospital (“TUBE early”) while 25 were sampled later (“TUBE late”).
Accuracy of a Provincial Prescription Database for Assessing Medication Adherence in Heart Failure Patients (2008)

These results suggest that PharmaNet data accurately reflect medication adherence for most patients. The MEMS system proved unreliable in several cases, illustrating the difficulty of identifying a gold standard for adherence assessment.
MCTF and scalability extension of H.264/AVC and its application to video transmission, storage, and surveillance (2005)

The extension of H.264/AVC hybrid video coding towards scalable video coding (SVC) using motion-compensated temporal filtering (MCTF) is presented. Utilizing the lifting approach to implement MCTF, the motion compensation features of H.264/AVC can be re-used for the MCTF prediction step and extended in a straightforward way for the MCTF update step. The MCTF extension of H.264/AVC is also incorporated into a video codec that provides SNR, spatial, and (similar to hybrid video coding) temporal scalability. The paper provides a description of these techniques and presents experimental results that validate their efficiency. In addition applications of SVC to video transmission and video surveillance are described.

Spectrum of HLA associations: the case of medically refractory pediatric acute lymphoblastic leukemia (2012)

Although studies of HLA and disease now date back some 50 years, a principled understanding of that relationship has been slow to emerge. Here, we examine the associations of three HLA loci with medically refractory pediatric acute lymphoblastic leukemia (pALL) patients in a case-control study involving 2,438 cases and 41,750 controls. An analysis of alleles from the class I loci, HLA-A and HLA-B, and the class II locus DRB1 illuminates a spectrum of extremely significant allelic associations conferring both predisposition and protection. Genotypes constructed from predisposing, protective, and neutral allelic categories point to an additive mode of disease causation. For all three loci, genotypes homozygous for predisposing alleles are at highest disease risk while the favorable effect of homozygous protective genotypes is less striking. Analysis of A-B and B-DRB1 haplotypes reveals locus-specific differences in disease effects, while that all three loci influence pALL; the influence of HLA-B is greater than that of HLA-A, and the predisposing effect of DRB1 exceeds that of HLA-B. We propose that the continuum in disease susceptibility suggests a system in which many alleles take part in disease predisposition based on differences in binding affinity to one or a few peptides of exogenous origin. This work provides evidence that an immune response mediated by alleles from several HLA loci plays a critical role in the pathogenesis of pALL, adding to the numerous studies pointing to a role for an infectious origin in pALL.
Electroless coating of Fe3Si on steel in the molten salt (2000)

The corrosion-resistive intermetallic compound Fe3Si could non-electrolytically coat pure iron and mild steel. The disproportional reaction between Si and Si4+ ions deposited the homogeneous Fe3Si layer on the Fe substrates, by using solid silicon and the molten salt composed of NaCl-KCl-NaF-Na2SiF6-SiO2. SiF4 gas evaporation prevented from continuous siliconization, when only Na2SiF6 was used as Si4+ ion source. By adding SiO2 into the salt as another source, the molten salt became endurable for repeated usage in air. The layer of Fe3Si single phase with silicon mole fractions of 24 ± 1 % grew thicker than 200 μm by immersing for a few hours at 973 – 1173K. Reines Eisen und kohlenstoffarme Stähle lassen sich mit der korrosionsfesten intermetallischen Verbindung Fe3Si ohne Elektrolyse beschichten. Die nicht proportionale Reaktion zwischen Si und Si4+-lonen sorgt mit Hilfe von festem Silicium und dem Salzbad bestehend aus NaCl-KCl-NaF-Na2SiF6-SiO2 für die Abscheidung einer homogenen Fe3Si-Schicht auf dem Eisensubstrat. Die SiF4-Verdampfung verhindert eine kontinuierliche Silicierung, solange ausschließlich Na2SiF6 als Si4+-lonenquelle dient. Gibt man dem Salz SiO2 als weitere lonenquelle hinzu, läßt sich das Salzbad für wiederholten Einsatz an Luft haltbar machen. Die einphasige Fe3Si-Schicht mit einem Siliciumstoffmengengehalt von 24 ± 1 % wird über 200 μm dick, wenn einige wenige Stunden bei 973 – 1173K eingetaucht wird.
Cover Picture: Solid‐State Molecular Nanomagnet Inclusion into a Magnetic Metal–Organic Framework: Interplay of the Magnetic Properties (Chem. Eur. J. 2/2016) (2015)

Solid-state incorporation of a single-ion magnet (SIM) within the pores of a magnetic 3D metal–organic framework (MOF) in a single-crystal to single-crystal process has been demonstrated. The resulting host–guest supramolecular aggregate affords the first deep study on the interplay of the internal magnetic field of the MOF and the slow magnetic relaxation of the SIM allowing the observation of a partial suppression of the quantum-tunneling effects operative in the SIM.

The effective microwave surface impedance of high T c thin films (1990)

The dependence of the effective surface impedance Zeff=Reff+iXeff of superconducting thin films on the film thickness d, on the magnetic field penetration depth λ, and on the dielectric properties of the substrate material is investigated theoretically by means of impedance transformations. It was found that the effective surface resistance Reff can be expressed by RSf(d/λ)+Rtrans where RS is the intrinsic surface resistance of the superconductor. The function f(d/λ) describes the altered current density distribution in the film. Rtrans arises from power transmission through the film. It depends on d and λ as well as on the dielectric properties of the substrate material and is significantly altered in the case of a resonant background. The effective surface reactance Xeff of a superconducting thin film can be expressed by XS cosh(d/λ) where XS=ωμ0λ is the intrinsic surface reactance. Measurements of Zeff at 87 GHz have been performed for YBa2Cu3O7−δ thin films grown epitaxially by laser ablation on SrTiO3, MgO, and LaAlO3. With the best films, Reff (77 K) values of 21 mΩ and RS (77 K) values of 8 mΩ were achieved. The temperature dependence of λ was found to be in good agreement to both weak-coupling BCS theory in the clean limit and the empirical two-fluid model relation with λ (0 K) values ranging from 140 to 170 nm and 205 to 250 nm, respectively.
Flowdometry: An Optical Flow and Deep Learning Based Approach to Visual Odometry (2017)

Visual odometry is a challenging task related to simultaneous localization and mapping that aims to generate a map traveled from a visual data stream. Based on one or two cameras, motion is estimated from features and pixel differences between frames. Because of the frame rate of the cameras, there are generally small, incremental changes between subsequent frames where optical flow can be assumed to be proportional to the physical distance moved by an egocentric reference, such as a camera on a vehicle. In this paper, a visual odometry system called Flowdometry is proposed based on optical flow and deep learning. Optical flow images are used as input to a convolutional neural network, which calculates a rotation and displacement for each image pixel. The displacements and rotations are applied incrementally to construct a map of where the camera has traveled. The proposed system is trained and tested on the KITTI visual odometry dataset, and accuracy is measured by the difference in distances between ground truth and predicted driving trajectories. Different convolutional neural network architecture configurations are tested for accuracy, and then results are compared to other state-of-the-art monocular odometry systems using the same dataset. The average translation error from the Flowdometry system is 10.77% and the average rotation error is 0.0623 degrees per meter. The total execution time of the system per optical flow frame is 0.633 seconds, which offers a 23.796x speedup over state-of-the-art methods using deep learning.
Effects of uremic toxins on hippocampal synaptic transmission: implication for neurodegeneration in chronic kidney disease (2021)

Patients affected by chronic kidney disease (CKD) have an increased risk of developing cognitive impairment. The cause of mental health disorders in CKD and in chronic hemodialysis patients is multifactorial, due to the interaction of classical cardiovascular disease risk factors, kidney- and dialysis-related risk factors with depression, and multiple drugs overuse. A large number of compounds, defined as uremic toxins that normally are excreted by healthy kidneys, accumulate in the circulations, in the tissues, and in the organs of CKD patients. Among the candidate uremic toxins are several guanidino compounds, such as Guanidine. Uremic toxins may also accumulate in the brain and may have detrimental effects on cerebral resident cells (neurons, astrocytes, microglia) and microcirculation. The present study aims to analyze the effect of Guanidine on hippocampal excitatory postsynaptic field potentials (fEPSPs) and in CA1 pyramidal neurons recorded intracellularly. Moreover, we compared these effects with the alterations induced in vitro by CKD patients derived serum samples. Our results show an increased, dose-dependent, synaptic activity in the CA1 area in response to both synthetic Guanidine and patient's serum, through a mechanism involving glutamatergic transmission. In particular, the concomitant increase of both NMDA and AMPA component of the excitatory postsynaptic currents (EPSCs) suggests a presynaptic mechanism. Interestingly, in presence of the lower dose of guanidine, we measure a significant reduction of EPSCs, in fact the compound does not inhibit GABA receptors allowing their inhibitory effect of glutamate release. These findings suggest that cognitive symptoms induced by the increase of uremic compounds in the serum of CKD patients are caused, at least in part, by an increased glutamatergic transmission in the hippocampus.
Blink rate as a measure of fatigue: A review. (1994)

Fatigue is one of many factors that can impact the ability of pilots and air traffic controllers (ATCs) to maintain their performance across time. This review of the literature is an outgrowth of a study concerning the relationship between several gaze measures and time on task (TOT) performance of subjects on an ATC monitoring task. Blink rate is one of several psychophysiological measures that has been proposed to assess fatigue associated with TOT. The acrimonious debate between Luckiesh and Tinker and Bitterman is evaluated and that portion of Luckiesh's results dealing with increases in blink rate as a function of TOT is well substantiated by the results of most other investigations. Some evidence is presented that variables, other than TOT, also affect blink rate, as well as data suggesting that the nature of the blink (blink closure duration) may be affected by TOT effects. The development of improved methodologies for detecting attentional lapses or the impaired ability of operators to perform on perceptually and cognitively demanding tasks will allow us to conduct improved evaluations of the effectiveness of various fatigue countermeasures.\n\n
Changes in Choroidal Thickness and Structure in Preeclampsia with Serous Retinal Detachment (2023)

Preeclampsia is a pregnancy-specific syndrome characterized by hypertension and proteinuria. We retrospectively investigated the clinical features, including choroidal layer thickness and luminal area to stromal area ratio, in a case series of preeclampsia with serous retinal detachment (SRD). The subjects were pregnant women with SRD during hospitalization for preeclampsia from October 2014 to June 2021. Based on medical records, affected eyes, time of onset, fundus examination findings, and subfoveal choroidal thickness (SCT), the choroidal layer thickness and choroidal vascular index (CVI) in each patient was examined. Thirteen eyes from seven patients (mean age 30.7 ± 4.7 years) were included in the study. In all cases, SRD improved without topical ocular treatment. The mean SCT at the initial visit was 424.4 ± 70.5 μm, and all patients had choroidal thickening, which significantly decreased to 286.0 ± 57.9 μm (p < 0.01) at the last visit. The mean choroidal inner layer was 162.7 ± 69.4 μm at the initial visit and 122.3 ± 35.5 μm at the final follow-up visit (p = 0.06), showing no significant difference; however, the mean choroidal outer layer was 261.7 ± 47.6 μm at the initial visit and 163.7 ± 37.1 μm at the final follow-up visit (p < 0.01), thus showing a significant decrease. The mean CVI was 67.2 ± 1.3% at the initial visit, yet it had significantly decreased to 65.4 ± 1.1% (p < 0.01) at the final follow-up visit. The findings of this study show that SRD with preeclampsia is associated with increased thickening of the choroidal outer layer, especially in the choroidal luminal area.
Empirical estimates of prostate cancer overdiagnosis by age and prostate-specific antigen (2014)

Prostate cancer overdiagnosis has a strong relationship to age and PSA level. Restricting screening in men over 60 to those with PSA above median (>1 ng/ml) and screening men over 70 only in selected circumstances would importantly reduce overdiagnosis and change the ratio of benefits to harms of PSA-screening.

Influence of reactive compatibilization on the structure and properties of PP/LDH nanocomposites (2011)

Abstract Polypropylene (PP)/layered double hydroxide (LDH) nanocomposites were prepared by the direct melt intercalation method using maleic anhydride grafted polypropylene (PP‐g‐MAH) as a reactive compatibilizer. The compatibilization effects provided by PP‐g‐MAH in different weight fractions and their influence on the structure and properties of the final nanocomposites were investigated. The interactions and structural morphology of the nanocomposites were examined by Fourier transform infrared spectroscopy, X‐ray diffraction and transmission electron microscopy. Thermal, mechanical and rheological properties of these nanocomposites were investigated as a function of compatibilizer concentration. The detailed morphological and X‐ray diffraction results revealed that the degree of LDH dispersion increases as the amount of PP‐g‐MAH increases. Study of the linear viscoelastic properties showed that the storage modulus G ′ is very sensitive to the microstructure of the nanocomposite. The thermal properties of the nanocomposites were significantly influenced by the weight fraction of PP‐g‐MAH due to the shielding and nucleating effect of exfoliated layers. Both the tensile strength and modulus showed substantial improvements with increasing PP‐g‐MAH content, while the elongation at break substantially decreased, although the presence of PP‐g‐MAH somewhat improves these values. The overall results showed that 10 wt% of compatibilizer is optimum to achieve nanocomposites with better performance. Copyright © 2011 Society of Chemical Industry
