FUNCIONALIDADES AVANZADAS DE DVB-T2 PARA EL DISEÑO DE REDES DE TELEVISION DIGITAL TERRESTRE EN LATINOAMÉRICA (2013)

espanolDVB-T2 es el estandar de segunda generacion para la radiodifusion de servicios de Television Digital Terrestre (TDT) a receptores fijos, portables y moviles. DVB-T2 se ha convertido en el medio de transporte mas eficiente para la radiodifusion de servicios de TV en alta definicion (HDTV) y television tridimensional (3DTV) en aquellos paises pioneros que ya han desplegado redes TDT2 tales como UK, Italia, Suecia y Finlandia. En este articulo se describen las novedosas funcionalidades de DVB-T2 que lo convierten en el mas avanzado sistema de transmision para TDT con un alto grado de eficiencia, flexibilidad y robustez que ningun otro estandar puede igualar. Se analiza la gran flexibilidad de configuracion y mejora en rendimiento del estandar DVB-T2 comparado con su antecesor DVB-T y con el estandar de television disenado inicialmente en Japon, modificado en Brasil y adoptado en la mayor parte de los paises de America del Sur conocido como ISDB-TB. Adicionalmente se identifican los principales beneficios de planificar y desplegar una nueva red de TDT en paises de Latinoamerica haciendo uso de las funcionalidades avanzadas de DVB-T2. La posibilidad de emitir hasta 4 programas de HDTV en un mismo canal multiplex, la configuracion de redes de frecuencia unica (SFN) de gran tamano y con una unica frecuencia nacional, la transmision de servicios para cualquier tipo de recepcion en un mismo canal RF y la existencia de cajas de recepcion o Set Top Box (STB) mas economicos gracias a las economias de escala de la familia de estandares DVB, son algunas de las ventajas que ofrece este nuevo estandar DVB-T2. EnglishDVB-T2 is a second-generation standard for terrestrial broadcasting aimed at broadcasting to fixed, portable and mobile receivers. DVB-T2 has become the most efficient standard to broadcasting High Definition Television services HDTV and threedimensional television 3DTV in pioneers countries that have already deployed TDT2 networks such as UK, Italy, Sweden and Finland. This article describes the novel features of DVB-T2 that become it in the most advanced transmission system for DTT with high level efficient, flexible and robustness like any other standard. We analyzed the configuration flexibility and performance of DVB-T2 compared with its predecessor DVB-T and Japanese standard ISDB-T adopted in some Latin America countries. Moreover, this article analyses the main benefits of planning and deploying new TDT networks in the Andean region using the advanced features of DVB-T2. The possibility of broadcasting up to five HDTV programs in the same multiplex, large SFN networks with only one national frequency, broadcasting services to different scenario reception in the same RF channel and cheaper set top box due to the economies of scales of DVB are some of the main advantages of this new standard.
Polymerization of Methyl Methacrylate with Samarocene Complex Supported on Mesoporous Silica (2001)

Samarocene complex was supported on a series of mesoporous silica with various pore sizes. Polymerization of methyl methacrylate (MMA) by these catalysts provide highly syndiotactic PMMAs with higher molecular weights compared with those obtained by solution polymerization with homogeneous catalyst system.
Mesoporous Piezoelectric Polymer Composite Films with Tunable Mechanical Modulus for Harvesting Energy from Liquid Pressure Fluctuation (2016)

Harvesting mechanical energy from biological systems possesses great potential for in vivo powering implantable electronic devices. In this paper, a development of flexible piezoelectric nanogenerator (NG) is reported based on mesoporous poly(vinylidene fluoride) (PVDF) films. Monolithic mesoporous PVDF is fabricated by a template-free sol-gel-based approach at room temperature. By filling the pores of PVDF network with poly(dimethylsiloxane) (PDMS) elastomer, the composite's modulus is effectively tuned over a wide range down to the same level of biological systems. A close match of the modulus between NG and the surrounding biological component is critical to achieve practical integration. Upon deformation, the composite NG exhibits appreciable piezoelectric output that is comparable to or higher than other PVDF-based NGs. An artificial artery system is fabricated using PDMS with the composite NG integrated inside. Effective energy harvesting from liquid pressure fluctuation (simulating blood pressure fluctuation) is successfully demonstrated. The simple and effective approach for fabricating mesoporous PVDF with tunable mechanical properties provides a promising route toward the development of self-powered implantable devices.
Timber characterisation using a non-invasive TDR sensor (2009)

This paper utilizes the technique of Time Domain Reflectometry (TDR) to aid in the characterization of timber. The electric field of TDR sensor is very sensitive to moisture trapped within the timber and can thus be used to infer anomalies in the grain down to a depth of approximately 10 cm below its surface. This novel application of non-invasive TDR indicates the presence of timber characteristics such as size and frequency of knots, splits and decay by a time series analysis of the propagation delays as the TDR sensor probe is moved along the timber surface.
Vulvar vestibulitis and interstitial cystitis: a disorder of urogenital sinus-derived epithelium? (1993)

Because both the vestibule of the vulva and the bladder are derived from the urogenital sinus, we propose that the coexistence of vulvar vestibulitis and interstitial cystitis in some patients represents a generalized disorder of urogenital sinus-derived epithelium.
Direct Observation of Magnetochiral Effects through a Single Metamolecule in Microwave Regions (2014)

We report direct observation of magnetochiral (MCh) effects for the X-band microwaves through a single metamolecule consisting of a copper chiral structure and ferrite rod. A fictitious interaction between chirality and magnetism is realized in the metamolecule without intrinsic electronic interactions. The MCh effects are induced at the resonant optical activities by applying a weak dc magnetic field of 1 mT, and are increased with the magnetic field. The nonreciprocal differences in refractive indices are evaluated to be 10^{-3} at 200 mT.

Preventing the First Cesarean Delivery (2012)

With more than one third of pregnancies in the United States being delivered by cesarean and the growing knowledge of morbidities associated with repeat cesarean deliveries, the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the Society for Maternal-Fetal Medicine, and the American College of Obstetricians and Gynecologists convened a workshop to address the concept of preventing the first cesarean delivery. The available information on maternal and fetal factors, labor management and induction, and nonmedical factors leading to the first cesarean delivery was reviewed as well as the implications of the first cesarean delivery on future reproductive health. Key points were identified to assist with reduction in cesarean delivery rates including that labor induction should be performed primarily for medical indication; if done for nonmedical indications, the gestational age should be at least 39 weeks or more and the cervix should be favorable, especially in the nulliparous patient. Review of the current literature demonstrates the importance of adhering to appropriate definitions for failed induction and arrest of labor progress. The diagnosis of "failed induction" should only be made after an adequate attempt. Adequate time for normal latent and active phases of the first stage, and for the second stage, should be allowed as long as the maternal and fetal conditions permit. The adequate time for each of these stages appears to be longer than traditionally estimated. Operative vaginal delivery is an acceptable birth method when indicated and can safely prevent cesarean delivery. Given the progressively declining use, it is critical that training and experience in operative vaginal delivery are facilitated and encouraged. When discussing the first cesarean delivery with a patient, counseling should include its effect on future reproductive health.

Enhancing polarisation imaging through novel polarimetry and adaptive optics (2022)

. Precise polarisation imaging requires two key aspects – imaging resolution and vector information correctness. Errors in the state of polarisation (SOP) can disrupt these two aspects hence leading to imperfect interference at the focus, and incorrect vector states in the illumination or detection. Those issues will therefore lead to detrimental problems for high resolution polarisation sensitive optical systems, such as Stokes/Mueller confocal microscopes. The SOP errors can be introduced in different ways, which include pre-measurement processes, such as denoising, optimisation, and calibration, which are built on matrix calculation processes which would introduce an error amplification; or, other errors sources in optical systems such as focusing through stressed optical elements, due to Fresnel’s effects, or induced via polarising effects in materials or biological tissues Here we put forward two techniques to deal with those errors, including next generation polarimetry and next generation adaptive optics techniques. We first show a new polarimetry method that has the ability to map all polarisation analyser states into a single vectorially structured light field, hence all vector components are analysed in a single-shot. We extract the vectorial state through inference from a physical model of the resulting image, providing a single-step sensing procedure. These methods in effect circumvent these method-related error amplification, accumulation and complex preprocessing steps. We then show a new adaptive optics technology that can correct both phase and polarisation aberrations within the optical systems. We validate improvements in both vector field state and the focal quality of an optical system, through correction for commonplace vectorial aberration sources.
Le point sur la ventilation mécanique invasive — Les nouveaux modes automatisés Latest developments for invasive mechanical ventilation — The new automated modes (2011)

L’automatisation de la ventilation, souvent designee par le terme de « boucle de regulation », existe depuis longtemps et sous diverses formes. Il est en effet necessaire pour les ventilateurs modernes de fonctionner avec differentes boucles de regulation, ne serait-ce que pour administrer correctement les debits precis ou les concentrations d’oxygene. Cependant, lorsqu’il s’agit des modes de ventilation, il est interessant de distinguer trois niveaux de boucles de regulation, de maniere un peu schematique, mais utile a la comprehension et a la classification de ces modes.
An objective multi-layer QoE Evaluation for TCP video streaming (2015)

It's a challenge to effectively assess Quality of Experience (QoE) for TCP video streaming with network performance parameters, to resolve this problem, an objective hierarchical Evaluation for Transmission Control Protocol (TCP) video streaming is proposed under video playback scenarios. QoE assessment for TCP video streaming is resolved into two sub-steps. In the first place, in consideration of video playback performance parameters affecting QoE, the authors demonstrate three novel application-layer metrics. Further, impact of network status on video playback performance is investigated and the authors propose high level network-layer parameters. Then the correlation between the network-layer parameters and application-layer metrics is characterized through analysis and inference. In the secondly place, subjective tests are conducted to evaluate QoE from application-layer metrics. Ultimately, the authors validate analysis and model by simulations and experiments in real networks. The experimental study shows that the proposed method performs well in assessing QoE of TCP video streaming.
The Antipsychotic Olanzapine Interacts with the Gut Microbiome to Cause Weight Gain in Mouse (2020)

The second-generation antipsychotic olanzapine is effective in reducing psychotic symptoms but can cause extreme weight gain in human patients. We investigated the role of the gut microbiota in this adverse drug effect using a mouse model. First, we used germ-free C57BL/6J mice to demonstrate that gut bacteria are necessary and sufficient for weight gain caused by oral delivery of olanzapine. Second, we surveyed fecal microbiota before, during, and after treatment and found that olanzapine potentiated a shift towards an “obesogenic” bacterial profile. Finally, we demonstrated that olanzapine has antimicrobial activity in vitro against resident enteric bacterial strains. These results collectively provide strong evidence for a mechanism underlying olanzapine-induced weight gain in mouse and a hypothesis for clinical translation in human patients.
Three Generations of Cobalt Porphyrins as Catalysts in the Oxidation of Cycloalkanes (2018)

Three generations of cobalt porphyrins were synthesized, physicochemically characterized by FTIR and UV/Vis spectroscopy as well as cyclic voltammetry and applied as catalysts in the oxidation of cycloalkanes with atmospheric molecular oxygen under mild conditions. All examined catalysts were active in the tested reaction, and their catalytic activity varied with the nature and number of substituents on the porphyrin ring. Introduction of electron-withdrawing or electron-donating substituents at the porphyrin rings increases the activity of metalloporphyrin complexes. It was found, for the first time, that generation II cobalt porphyrins show higher activity in cycloalkane oxidation than cobalt porphyrins of generation III. The lower catalytic activity of generation III cobalt porphyrins can be attributed to the saddle-shaped deformation of the porphyrin macrocycle. DFT modeling of Co porphyrins and their interactions with molecular oxygen provided explanations for the observed effects. On the basis of prior reports and the obtained results, a reaction mechanism is proposed and discussed.
Free IGF-1, Intact IGFBP-4, and PicoPAPP-A are Altered in Acute Myocardial Infarction Compared to Stable Coronary Artery Disease and Healthy Controls (2018)

Insulin-like growth factor-1 (IGF-1) and its binding proteins have been implicated in the pathophysiology of coronary artery disease (CAD) and myocardial infarction (MI). We investigated components of the IGF-1 system in circulation at the time of acute MI and following reperfusion in relation to levels of stable CAD patients and controls. Patients with MI (MI Group, n=31) treated with percutaneous coronary intervention (PCI) were compared to patients with stable CAD subjected to scheduled PCI (CAD Group, n=40) and controls with symptoms mimicking CAD without stenosis in angiography (Control Group, n=43). The number and extent of stenosis were recorded. Total and free IGF-1, total and intact IGF binding protein (IGFBP)-3 and -4, pico-Pregnancy Associated Plasma Protein-A (PAPP-A), and the known markers ALT, AST, CK and CK-MB were measured at baseline and 6 or 24 h after the intervention. Patients with MI had higher free IGF-1 (p=0.003) and PAPP-A (p=0.011), but lower intact IGFBP-4 (p=0.006) compared with patients with stable CAD or healthy controls. None of the investigated molecules changed following reperfusion or correlated with the extent of stenosis. AST (p<0.001), CK (p<0.001) and CK-MB (p<0.001), were also higher. Free IGF-1, intact IGFBP-4 and PAPP-A could predict MI, but with lower accuracy than CK-MB. In conclusion, free IGF-1 levels are higher in MI compared to CAD patients and controls and this could result from increased cleavage of its binding protein IGFBP-4 by the higher PAPP-A levels. Free IGF-1, intact IGFBP-4, and/or PAPP-A are inferior to CK-MB as predictors or markers of myocardial damage.
Endocytosis of androgen-binding protein, clusterin, and transferrin in the efferent ducts and epididymis of the ram. (1991)

The amount of androgen-binding protein (ABP) in luminal fluid from the central caput epididymidis of the ram, on a per sperm basis, remains the same as that in rete testis fluid (RTF) entering the ductuli efferentes, although greater than 85% of the testicular protein is absorbed in proximal sites. To determine if ABP is spared from endocytosis in proximal sites and if proteins are differentially and selectively absorbed at specific sites in the excurrent ducts, we studied the endocytosis of ABP, clusterin, transferrin, and a 26/35-kd dimer isolated from ovine RTF. Each protein was labeled with colloidal gold and microinjected into the lumen of a ductulus efferens and five specific sites in the ductus epididymidis; uptake was quantified by electron microscopy. Endocytosis of each protein, including ABP, was substantially greater in the ductuli efferentes than in any site in the ductus epididymidis. More ABP was endocytosed in proximal regions of the epididymis than any other protein studied. Endocytosis of the 26/35-kd dimer, like ABP, was greater in proximal sites of the epididymis, whereas endocytosis of clusterin and transferrin was greater in distal sites. Thus, there was a differential absorption, since proteins were endocytosed in one or another specific region of the epididymis, depending on the protein. ABP was endocytosed in the ductuli efferentes and caput epididymidis in amounts similar to or greater than other major testicular proteins, and was not spared from endocytosis in the proximal excurrent ducts.(ABSTRACT TRUNCATED AT 250 WORDS)
Effect of β-Si3N4 Initial Powder Size on Texture Development of Porous Si3N4 Ceramics Prepared by Gel-Casting in a Magnetic Field (2016)

Textured porous Si3N4 ceramics with fine and coarse β-Si3N4 powders as the raw materials were prepared by gel casting in a strong magnetic field of 6T and subsequent pressureless sintering. These results showed that highly textured porous Si3N4 ceramics could be obtained by adjusting the ratio between fine and coarse β-Si3N4 powders in 6T. The Lotgering orientation factor in green bodies showed the value of 0.72∼0.74 with the increase of coarse powder content. The sintering process promoted texture development of the samples by Ostwald ripening owing to the big difference in the β-Si3N4 initial powder size. After sintering at 1800oC for 2 h, the degree of texture (Lotgering orientation factor) in the sample, prepared with fine and coarse powders at the ratio of 1:1, reached the maximum value (0.91), and it had relatively high density (66.91%) and low apparent porosity (34.51%). The crystallographic texture in porous Si3N4 ceramics led to the anisotropic bending strength. The method combined with gel casting in a strong magnetic field was beneficial for preparing highly textured porous ceramics with big and complex shape.
Dynamic Optimization through the use of Automatic Runtime Specialization (1999)

Profile­-driven optimizations and dynamic optimization through specialization have taken optimizations to a new level. By using actual run­time data, optimizers can generate code that is specially tuned for the task at hand. However, most existing compilers that perform these optimizations require separate test runs to gather profile information, and/or user annotations in the code. In this thesis, I describe run­time optimizations that a dynamic compiler can perform automatically --- without user annotations --- by utilizing real­time performance data. I describe the implementation of the dynamic optimizations in the framework of a Java Virtual Machine and give performance results.
Fusarium oxysporum f. sp. lycopersici causal agent of vascular wilt disease of tomato: Biology to diversity– A review (2019)

Tomato (<i>Lycopersicon esculentum</i>) is one of the widely grown vegetables worldwide. <i>Fusarium oxysporum</i> f. sp. <i>lycopersici</i> (<i>FOL</i>) is the significant contributory pathogen of tomato vascular wilt. The initial symptoms of the disease appear in the lower leaves gradually, trail by wilting of the plants. It has been reported that <i>FOL</i> penetrates the tomato plant, colonizing and leaving the vascular tissue dark brown, and this discoloration extends to the apex, leading to the plants wilting, collapsing and dying. Therefore, it has been widely accepted that wilting caused by this fungus is the result of a combination of various physiological activities, including the accumulation of fungal mycelia in and around xylem, mycotoxin production, inactivation of host defense, and the production of tyloses; however, wilting symptoms are variable. Therefore, the selection of molecular markers may be a more effective means of screening tomato races. Several studies on the detection of <i>FOL</i> have been carried out and have suggested the potency of the technique for diagnosing <i>FOL</i>. This review focuses on biology and variability of <i>FOL</i>, understanding and presenting a holistic picture of the vascular wilt disease of tomato in relation to disease model, biology, virulence. We conclude that genomic and proteomic approachesare greater tools for identification of informative candidates involved in pathogenicity, which can be considered as one of the approaches in managing the disease.
A comparison of technology trajectories between the global and the United States in smart grid (2011)

This study aims to compare the technology trajectories between the United States (U.S.) and the global nations in the smart grid field. Highly cited patents were collected from 2001/1/1 to 2010/12/31 and then were analyzed through bibliographic coupling method, sliding TCT-based citation window and Girvan-Newman clustering for being converted into a global technology trajectory map as well as a U.S. one. Firstly, results show that three of the global technology trajectories are time-lagged than its counterparts of the U.S. one, including electronic trading, dynamic power and workload management, and network monitoring through user profiles. Secondly, we found that two of the U.S. technology trajectories does exist but cannot be found in the global map, containing remote monitoring, automatic trading process and interface circuit system. Lastly, the conditional purchase offer management (CPO Management) and also the dynamic policy management (DPM) of the global trajectories are missing in the U.S. map.
