Sobrevida y libertad de reoperación en pacientes sometidos a tratamiento endovascular de enfermedades de la aorta (2018)

Introduction: The endovascular management for diseases of the aorta has increased as an option for patients of high risk for conventional open surgery. The short-term mortality, disease-free and reoperation results, show favourable outcomes compared to open surgery, but there are no results available in this country for the medium (1-12 months) and long-term (&gt;1 year). Methods: A bi-directional cohort study, in which the retrospective segment was conducted on patients subjected to endovascular management with an aortic replacement, and the prospective segment on the follow-up of the patients. Results: A total of 194 patients, subjected to endovascular treatment and met the inclusion criteria, were identified between April 2002 and December 2015. The follow-up was completed in 82.2% of cases. There were 92 (56.8%) cases of abdominal aorta with a mean follow-up of 4.9 years (95% range; 2.5-8.9). The calculated survival was 92% at one year, 86% at 2 years, and 66.4% at 5 years. The period free of disease was 88.7% at one year, 86.4% at 2 years, and 78.5% at 10 years, with 13 patients requiring re-operation. There were 67 cases of thoracic aorta, with a mean follow-up of 5.3 years (95% range; 2.9-10.2). The calculated survival was 94% at one year, 90.7% at 2 years, and 75.2% at 5 years. The period free of disease was 88.7% at one year, 86.4% at 2 years, and 78.5% at 10 years, and 9 patients required re-operation. Conclusions: The results obtained are favourable and are encouraging to continue offering the endovascular approach since the re-operation survival is similar to that reported in the literature. © 2018 Sociedad Colombiana de Cardiología y Cirugía Cardiovascular
Decomposition synthesis of tuneable, macroporous carbon foams from crystalline precursors via in situ templating (2014)

A flexible, sustainable, one-step thermal decomposition route for the synthesis of hierarchical, heteroatom doped carbon foams is presented. Task-specific semi-organic crystals combine functions for three different purposes: the carbon and heteroatom source, a foaming agent (CO2) and an in situ generable template (NaCl). Insights to the decomposition pathway were gained through FTIR/MS coupled TGA and an ultrafast out-of-furnace heating procedure and the products were analysed with (HR)SEM/TEM, EELS, FTIR, and N2 sorption. The resulting macroporous carbon foams are excellent supports for metallic nanoparticles due to their hierarchical structure, high surface area and tuneable heteroatom contents. This was demonstrated for catalytically active copper or the magnetic CoNi alloy for water purification.
Group <scp>VII E</scp>thylene <scp>R</scp>esponse <scp>F</scp>actor diversification and regulation in four species from flood‐prone environments (2014)

Flooding events negatively affect plant performance and survival. Flooding gradients thereby determine the dynamics in vegetation composition and species abundance. In adaptation to flooding, the group VII Ethylene Response Factor genes (ERF-VIIs) play pivotal roles in rice and Arabidopsis through regulation of anaerobic gene expression and antithetical survival strategies. We investigated if ERF-VIIs have a similar role in mediating survival strategies in eudicot species from flood-prone environments. Here, we studied the evolutionary origin and regulation of ERF-VII transcript abundance and the physiological responses in species from two genera of divergent taxonomic lineages (Rumex and Rorippa). Synteny analysis revealed that angiosperm ERF-VIIs arose from two ancestral loci and that subsequent diversification and duplication led to the present ERF-VII variation. We propose that subtle variation in the regulation of ERF-VII transcript abundance could explain variation in tolerance among Rorippa species. In Rumex, the main difference in flood tolerance correlated with the genetic variation in ERF-VII genes. Large transcriptional differences were found by comparing the two genera: darkness and dark submergence-induced Rumex ERF-VIIs, whereas HRE2 expression was increased in submerged Rorippa roots. We conclude that the involvement of ERF-VIIs in flooding tolerance developed in a phylogenetic-dependent manner, with subtle variations within taxonomic clades.

Design of 120&amp;#x2236;1 frequency divider for a 12.6 GHz phase-locked loop (2014)

A 120:1 frequency divider in 65-nm CMOS process is proposed. As a critical part of a 12.6 GHz PLL, the divider circuit divides the 12.6 GHz signal by a factor of 120 to achieve a 105 MHz reference signal. The design includes an 8:1 analog common mode logic (CML) divider followed by a 15:1 digital frequency divider. The measurement results show that it achieves a low phase noise of -109 dBc/Hz at 1 MHz offset, and a wide locking range from 8.3 GHz to 13.9 GHz. The size of the fabricated divider is 0.3 × 0.1 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .
Structure Analysis of ZnO–TeO<sub>2</sub> Glasses by Means of Neutron Diffraction and Molecular Dynamics (1996)

Structures of x ZnO–(1- x ) TeO 2 glasses ( x =0.1, 0.2, 0.3) were investigated by means of neutron diffraction and molecular dynamics. Modified Keating three-body potential and imaginary negative point charge were applied to the simulation, which successfully represented complex structure units in tellurite glasses. It was concluded that TeO 3+1 was a dominant component in the network structure of the zinc tellurite glasses. The fraction of the TeO 3+1 unit was almost independent of the amount of ZnO. Zinc atoms are considered to play a role in network formation in the glasses, which was estimated on the basis of the coordination state of tellurium.
Universal Value Function Approximators (2015)

Value functions are a core component of reinforcement learning systems. The main idea is to to construct a single function approximator V (s; θ) that estimates the long-term reward from any state s, using parameters θ. In this paper we introduce universal value function approximators (UVFAs) V (s, g; θ) that generalise not just over states s but also over goals g. We develop an efficient technique for supervised learning of UVFAs, by factoring observed values into separate embedding vectors for state and goal, and then learning a mapping from s and g to these factored embedding vectors. We show how this technique may be incorporated into a reinforcement learning algorithm that updates the UVFA solely from observed rewards. Finally, we demonstrate that a UVFA can successfully generalise to previously unseen goals.
Manufacture and demonstration of organic photovoltaic‐powered electrochromic displays using roll coating methods and printable electrolytes (2012)

Abstract Electrochromic devices (ECDs) were prepared on flexible substrates using spray coating and slot‐die coating methods. The electrochromic materials were the conjugated electroactive polymers, poly((2,2‐bis(2‐ethylhexyloxymethyl)‐propylene‐1,3‐dioxy)‐3,4‐thiophene‐2,5‐diyl) as a vibrantly colored active material (ECP‐Magenta) and poly( N ‐octadecyl‐(propylene‐1,3‐dioxy)‐3,4‐pyrrole‐2,5‐diyl) as a minimally colored, charge balancing material (MCCP). Two electrolyte systems were compared to allow development of fully printable and laminated devices on flexible substrates. Devices of various sizes, up to 7 × 8 cm 2 , are demonstrated with pixelated devices containing pixel sizes of 4 × 4 mm 2 or 13 × 13 mm 2 . The transmission contrast exhibited by the devices, when switched between the fully bleached and fully colored state, was 58% at a visible wavelength of 550 nm, and the devices exhibited switching times of &lt;10 s. Additionally, we demonstrate the utilization of printed organic photovoltaic devices (with or without the use of a lithium‐polymer battery) to power the devices between the colored and bleached state, illustrating a self‐powered ECD. © 2012 Wiley Periodicals, Inc.

Real-Time Analysis of Hand Gesture Recognition with Temporal Convolutional Networks (2022)

In recent years, the successful application of Deep Learning methods to classification problems has had a huge impact in many domains. (1) Background: In biomedical engineering, the problem of gesture recognition based on electromyography is often addressed as an image classification problem using Convolutional Neural Networks. Recently, a specific class of these models called Temporal Convolutional Networks (TCNs) has been successfully applied to this task. (2) Methods: In this paper, we approach electromyography-based hand gesture recognition as a sequence classification problem using TCNs. Specifically, we investigate the real-time behavior of our previous TCN model by performing a simulation experiment on a recorded sEMG dataset. (3) Results: The proposed network trained with data augmentation yields a small improvement in accuracy compared to our existing model. However, the classification accuracy is decreased in the real-time evaluation, showing that the proposed TCN architecture is not suitable for such applications. (4) Conclusions: The real-time analysis helps in understanding the limitations of the model and exploring new ways to improve its performance.
An Angiotensin II (Ang II) Type 1 Receptor Blocker, Telmisartan, Improves Insulin Resistance in KK-A(y) Diabetic Mice. (2006)

Metabolic syndrome is strongly associated with insulin resistance and consists of a constellation of factors such as hypertension and hyperlipidemia that raise the risk for cardiovascular diseases and diabetes mellitus. The renin-angiotensin system (RAS) plays a pivotal role in the pathogenesis of diabetes and cardiovascular disease (CVD) in hypertensive patients. Further, recently, the interruption of the RAS has been shown to prevent the onset of diabetes in hypertensive patients. However, whether telmisartan, an angiotensin II type 1 receptor blocker (ARB) with selective peroxisome proliferator-activated receptor-γ (PPAR-γ) agonistic property could improve insulin sensitivity is not fully understood. In this study, we studied the effects of telmisartan on insulin sensitivity in KK-A(y) mice, an obese type 2 diabetic animal. Although there was no significant difference in body weight, food consumption, and glucose levels between the two groups, plasma insulin, triglycerides and non-esterified fatty acid levels were significantly decreased in telmisartan-treated KK-A(y) mice, compared with control KK-A(y) mice. The present findings suggest that telmisartan could exert a beneficial effect on insulin sensitivity in diabetic animals. Inhibition of the RAS by telmisartan, a selective agonist of PPAR-γ, may become a promising strategy for the treatment of hypertensive patients with metabolic syndrome and/or insulin resistance.
A coordinated multipoint transmission method employing vehicle position information for taxi radio systems (2016)

This paper proposes a simple coordinated multipoint (CoMP) transmission method for taxi radio systems. The feature of the proposed method is to realize CoMP only by using the vehicle position information, which enables us to free from a significant renewal of facilities. The proposed approach is inspired by the idea that the channel capacity based on the inter-cell interference (ICI) can be represented by the communication distance which is easily obtained from the vehicle position information. In addition, the proposed method is applicable to more than 3 cells by using the same approach applied to 2 cells. The effectiveness of the proposed method is demonstrated in comparison with the case of no coordination (w/o CoMP) under the practical scenario based on the taxi radio system.

Ambipolar transport in Mn2CoAl films by ionic liquid gating (2017)

We demonstrate ambipolar transport and modulation of electronic properties of Mn2CoAl (MCA), one of the most promising candidates for spin gapless semiconductors (SGSs), by using ionic liquid gating in electronic double-layer transistors. The carrier concentration and mobility of MCA films were systematically changed with carrier polarity inversion from the p- to the n-type by the gating technique. The ambipolar transport is one of the most significant properties of SGSs and strongly promotes the gapless features of MCA. The present results pave the way for the use of MCA as a spin source of both spin-polarized electrons and holes.
Type 1 and type 2 cytokine dysregulation in human infectious, neoplastic, and inflammatory diseases (1996)

In the mid-1980s, Mosmann, Coffman, and their colleagues discovered that murine CD4+ helper T-cell clones could be distinguished by the cytokines they synthesized. The isolation of human Th1 and Th2 clones by Romagnani and coworkers in the early 1990s has led to a large number of reports on the effects of Th1 and Th2 on the human immune system. More recently, cells other than CD4+ T cells, including CD8+ T cells, monocytes, NK cells, B cells, eosinophils, mast cells, basophils, and other cells, have been shown to be capable of producing "Th1" and "Th2" cytokines. In this review, we examine the literature on human diseases, using the nomenclature of type 1 (Th1-like) and type 2 (Th2-like) cytokines, which includes all cell types producing these cytokines rather than only CD4+ T cells. Type 1 cytokines include interleukin-2 (IL-2), gamma interferon, IL-12 and tumor necrosis factor beta, while type 2 cytokines include IL-4, IL-5, IL-6, IL-10, and IL-13. In general, type 1 cytokines favor the development of a strong cellular immune response whereas type 2 cytokines favor a strong humoral immune response. Some of these type 1 and type 2 cytokines are cross-regulatory. For example, gamma interferon and IL-12 decrease the levels of type 2 cytokines whereas IL-4 and IL-10 decrease the levels of type 1 cytokines. We use this cytokine perspective to examine human diseases including infections due to viruses, bacteria, parasites, and fungi, as well as selected neoplastic, atopic, rheumatologic, autoimmune, and idiopathic-inflammatory conditions. Clinically, type 1 cytokine-predominant responses should be suspected in any delayed-type hypersensitivity-like granulomatous reactions and in infections with intracellular pathogens, whereas conditions involving hypergammaglobulinemia, increased immunoglobulin E levels, and/or eosinophilia are suggestive of type 2 cytokine-predominant conditions. If this immunologic concept is relevant to human diseases, the potential exists for novel cytokine-based therapies and novel cytokine-directed preventive vaccines for such diseases.
Direct Synthesis of Photosensitive Poly(benzoxazole) (2001)

Poly(o-hydroxyamide) (3) as a poly(benzoxazole) precursor was prepared by the polycondensation of 2, 2-bis(3-amino-4-hydroxyphenyl)hexafluoropropane (1) and N, N′-isophtaloylbis(benzoxazoline-2-thione) (2) in N-methylpyrrolidinone. The resist from the polymerization solution was formulated with diazonaphtoquinone without isolation of 3. A clear positive pattern with 8μm line and space could be obtained when the film was exposed to g-line (436nm), followed by developing with a 0.8wt% aqueous tetramethylammoniumhydroxide (TMAH) solution. The sensitivity and contrast were determined g-line as 80mJ/cm2 and 2.2 respectively. The positive image was successfully converted to poly(benzoxazole) pattern by thermal treatment.
A novel, ataxic mouse model of Ataxia Telangiectasia caused by a clinically relevant nonsense mutation (2020)

Abstract Ataxia Telangiectasia (A-T) and Ataxia with Ocular Apraxia Type 1 (AOA1) are devastating neurological disorders caused by null mutations in the genome stability genes, A-T mutated ( ATM ) and Aprataxin ( APTX ), respectively. Our mechanistic understanding and therapeutic repertoire for treating these disorders is severely lacking, in large part due to the failure of prior animal models with similar null mutations to recapitulate the characteristic loss of motor coordination (i.e., ataxia) and associated cerebellar defects. By increasing genotoxic stress through the insertion of null mutations in both the Atm (nonsense) and Aptx (knockout) genes in the same animal, we have generated a novel mouse model that for the first time develops a progressively severe ataxic phenotype associated with atrophy of the cerebellar molecular layer. We find biophysical properties of cerebellar Purkinje neurons are significantly perturbed (e.g., reduced membrane capacitance, lower action potential thresholds, etc.), while properties of synaptic inputs remain largely unchanged. These perturbations significantly alter Purkinje neuron neural activity, including a progressive reduction in spontaneous action potential firing frequency that correlates with both cerebellar atrophy and ataxia over the animal’s first year of life. Double mutant mice also exhibit a high predisposition to developing cancer (thymomas) and immune abnormalities (impaired early thymocyte development and T-cell maturation), symptoms characteristic of A-T. Lastly, by inserting a clinically relevant nonsense-type null mutation in Atm , we demonstrate that S mall M olecule R ead- T hrough (SMRT) compounds can restore ATM production, indicating their potential as a future A-T therapeutic.

Physical Layer Anti-jamming Technique Using Massive Planar Antenna Arrays (2020)

Wirelessly connected devices play a vital role in people's daily life, especially with the significant rise in the number of devices connected to the Internet and the huge data being generated everyday. However, the open nature of the wireless channels makes them vulnerable to several threats. One of these major threats is jamming attacks which try to disrupt the reception of the useful signal by a receiver. In this paper, we propose a physical layer security anti-jamming method using massive planar antenna arrays. A receiver is assumed to perform anti-jamming against a single jammer trying to degrade the communication link between two parties. A large database of possible antenna array configurations with different radiation patterns is generated. Two methods are proposed for searching through the database. In the first, searching through the database gives the configuration with the deepest null towards the jammer, while in the second, we identify the configuration with the largest maximum to null ratio. The signal-to-interference-plus-noise-ratio is the chosen metric of performance for evaluating the chosen array configurations by both methods. Supporting simulation results validate the effectiveness of the proposed anti-jamming strategy.
Bias-Compensated Diffusion Pseudolinear Kalman Filter Algorithm for Censored Bearings-Only Target Tracking (2019)

This letter proposes a novel bias-compensated diffusion pseudolinear Kalman filter algorithm for censored bearings-only target tracking. The proposed algorithm considers two biases caused by the censored bearing angle measurements and the correlation between the measurement vector and the pseudolinear noise. First, the inverse Mills ratio is used to rebuild the uncensored measurements, which can efficiently compensate the bias arising from the censored measurements. Then, we present a bias analysis for the censored diffusion pseudolinear Kalman filter to develop a bias compensation method, leading to the BC-DPLKF-C algorithm. Simulation results show the improved performance of the proposed Kalman filter compared with existing algorithms.

The scoring system indicated several significant correlations between the score and preoperative patient status.
All-fiber laser source for CARS microscopy based on fiber optical parametric frequency conversion (2012)

A novel approach for an all-fiber mono-laser source for CARS microscopy is presented. An Yb-fiber laser generates 100 ps pulses, which later undergo narrowband in-fiber frequency conversion based on degenerate four-wave-mixing. The frequency conversion is optimized to access frequency shifts between 900 and 3200cm-1, relevant for vibrational imaging. Inherently synchronized pump and Stokes pulses are available at one fiber end, readily overlapped in space and time. The source is applied to CARS spectroscopy and microscopy experiments in the CH-stretching region around 3000cm-1. Due to its simplicity and maintenance-free operation, the laser scheme holds great potential for bio-medical applications outside laser laboratories.
