El efecto de la relajación en pacientes con lumbalgia

Introducción: En Colombia, la lumbalgia es la tercera causa de consulta en los servicios de emergencia y la cuarta causa de consulta a medicina general. Del mismo modo, la carga de enfermedad es elevada, pues se deben tener en cuenta el costo de tratamiento y la incapacidad. Los tratamientos farmacológicos convencionales han demostrado su efectividad frente al placebo, aunque se han identificado efectos secundarios indeseables. En el tratamiento no farmacológico para el manejo de la lumbalgia han surgido las técnicas de relajación como importante y eficiente modalidad terapéutica y se han descrito modelos por los cuales la relajación podría alcanzar el alivio en las personas con lumbalgia. Objetivos: Realizar una revisión crítica, profunda y actualizada de la literatura sobre el efecto de la relajación en el tratamiento de la lumbalgia. Método: En el servidor Medline se cruzaron las expresiones MeSH mind-body therapies, relaxation therapy y back pain y se delimitaron los resultados a los estudios que tuvieran resúmenes disponibles, que fueran ensayos clínicos y metaanálisis, además de que estuvieran en inglés o español. Al final se obtuvieron 40 artículos. Conclusiones: La técnicas de relajación son un tratamiento efectivo en pacientes con lumbalgia. De su aplicación se beneficiarían grandes grupos de pacientes y su implementación reduciría los costos relacionados con la enfermedad; sin embargo, se necesitan mayores estudios sobre el tema.
Quantum criticality of one-dimensional multicomponent Fermi gas with strongly attractive interaction

Quantum criticality of strongly attractive Fermi gas with SU ( 3 ) ? > symmetry in one dimension is studied via the thermodynamic Bethe ansatz (TBA) equations. The phase transitions driven by the chemical potential &mgr; ? > , effective magnetic field H1, H2 (chemical potential biases) are analyzed at the quantum criticality. The phase diagram and critical fields are analytically determined by the TBA equations in the zero temperature limit. High accurate equations of state, scaling functions are also obtained analytically for the strong interacting gases. The dynamic exponent z = 2 ? > and correlation length exponent &ngr; = 1 / 2 ? > read off the universal scaling form. It turns out that the quantum criticality of the three-component gases involves a sudden change of density of states of one cluster state, two or three cluster states. In general, this method can be adapted to deal with the quantum criticality of multicomponent Fermi gases with SU ( N ) ? > symmetry.
Griffiths phase and its evolution with Mn-site disorder in the half-doped manganite Pr 0.5 Sr 0.5 Mn 1 − y Ga y O 3 ( y = 0.0 , 0.025, and 0.05)

We show Griffiths phase (GP)-like behavior in half-doped ${\text{Pr}}_{0.5}{\text{Sr}}_{0.5}{\text{MnO}}_{3}$ having ferromagnetic (FM) spin correlation above FM transition $({T}_{C})$ without any spontaneous magnetization. Temperature range and exponent of GP increase with Ga substitution at Mn site which is not related with structural disorder as Ga does not affect the structure, moreover, reduces Jahn-Teller active ${\text{Mn}}^{3+}$ ions. FM clusters both above and below ${T}_{C}$ reduces their size with Ga. Hence, it is considered that GP originates from phase inhomogeneity and evolves with addition of disorder due to change in its length scale.
Spontaneous Imbibition Oil Recovery by Natural Surfactant/Nanofluid: An Experimental and Theoretical Study

Organic surfactants have been utilized with different nanoparticles in enhanced oil recovery (EOR) operations due to the synergic mechanisms of nanofluid stabilization, wettability alteration, and oil-water interfacial tension reduction. However, investment and environmental issues are the main concerns to make the operation more practical. The present study introduces a natural and cost-effective surfactant named Azarboo for modifying the surface traits of silica nanoparticles for more efficient EOR. Surface-modified nanoparticles were synthesized by conjugating negatively charged Azarboo surfactant on positively charged amino-treated silica nanoparticles. The effect of the hybrid application of the natural surfactant and amine-modified silica nanoparticles was investigated by analysis of wettability alteration. Amine-surfactant-functionalized silica nanoparticles were found to be more effective than typical nanoparticles. Amott cell experiments showed maximum imbibition oil recovery after nine days of treatment with amine-surfactant-modified nanoparticles and fifteen days of treatment with amine-modified nanoparticles. This finding confirmed the superior potential of amine-surfactant-modified silica nanoparticles compared to amine-modified silica nanoparticles. Modeling showed that amine surfactant-treated SiO2 could change wettability from strongly oil-wet to almost strongly water-wet. In the case of amine-treated silica nanoparticles, a strongly water-wet condition was not achieved. Oil displacement experiments confirmed the better performance of amine-surfactant-treated SiO2 nanoparticles compared to amine-treated SiO2 by improving oil recovery by 15%. Overall, a synergistic effect between Azarboo surfactant and amine-modified silica nanoparticles led to wettability alteration and higher oil recovery.
A hardware architecture of skip/direct mode for AVS3

Skip/direct mode is one of the inter prediction modes in video coding, which achieves a high coding performance. In Audio and Video coding Standard-3(AVS3), skip/direct has improved more performance with more candidate modes. The candidate mode list is generated by numerous prediction directions with corresponded predicted motion vectors. However, it will result in higher computation complexities and challenges to parallel computation, especially for the hardware implementation. For resolving the problem, we propose a hardware architecture of skip/direct mode with a fast motion vector prediction (MVP) algorithm in this paper. Our architecture is designed with efficient pipeline schedules. And the fast MVP algorithm can reduce the number of MVP candidates efficiently. The fast MVP method is introduced by setting a search window, some unnecessary MVP are skipped, thereby reducing the computational complexity firstly. Then the proposed hardware architecture is given with efficient pipeline schedules in detail. The experimental results show that our architecture is able to meet the requirement of 3840x2160@60FPS with only 0.48% and 0.42% BD-Rate increase under the low delay P (LDP) and random access (RA) configurations, respectively.
The AARTFAAC All Sky Monitor: System Design and Implementation

The Amsterdam-ASTRON Radio Transients Facility And Analysis Center (AARTFAAC) all sky monitor is a sensitive, real time transient detector based on the Low Frequency Array (LOFAR). It generates images of the low frequency radio sky with spatial resolution of 10s of arcmin, MHz bandwidths, and a time cadence of a few seconds, while simultaneously but independently observing with LOFAR. The image timeseries is then monitored for short and bright radio transients. On detection of a transient, a low latency trigger will be generated for LOFAR, which can interrupt its schedule to carry out follow-up observations of the trigger location at high sensitivity and resolutions. In this paper, we describe our heterogeneous, hierarchical design to manage the 240 Gbps raw data rate, and large scale computing to produce real-time images with minimum latency. We discuss the implementation of the instrumentation, its performance, and scalability.
The Effect of Redshift Distortions on the Integrated Sachs-Wolfe Signal

We show that linear redshift distortions in the galaxy distribution can affect the ISW galaxy-temperature signal, when the galaxy selection function is derived from a redshift survey. We find this effect adds power to the ISW signal at all redshifts and is larger at higher redshifts. Omission of this effect leads to an overestimation of the dark energy density $\Omega_\Lambda$ as well as an underestimation of statistical errors. We find a new expression for the ISW Limber equation which includes redshift distortions, though we find that Limber equations for the ISW calculation are ill-suited for tomographic calculations when the redshift bin width is small. The inclusion of redshift distortions provides a new cosmological handle in the ISW spectrum, which can help constrain dark energy parameters, curvature and alternative cosmologies. Code is available on request and will soon be added as a module to the iCosmo platform (this http URL)
Exchange coupling in silicon quantum dots: Theoretical considerations for quantum computation

We study exchange coupling in Si double quantum dots, which have been proposed as suitable candidates for spin qubits due to their long spin coherence times. We discuss in detail two alternative schemes which have been proposed for implementing spin qubits in quantum dots. One scheme uses spin states in a single dot and the interdot exchange coupling controls interactions between unbiased dots. The other scheme employs the singlet and triplet states of a biased double dot as the two-level system making up the qubit and exchange controls the energy splitting of the levels. Exchange in these two configurations depends differently on system parameters. Our work relies on the Heitler-London approximation and the Hund-Mulliken molecular orbital method. The results we obtain enable us to investigate the sensitivity of the system to background charge fluctuations and determine the conditions under which optimal spots, at which the influence of the charge noise is minimized, may exist in Si double quantum dot structures.
Ecosystem Services Valuation for Estuarine and Coastal Restoration in Florida

Throughout Florida’s history, humans have altered the coastlines, leading to large-scale degradation of coastal ecosystems. This has led to the loss of associated ecosystem services, including products such as food and timber, and processes like coastal protection and disease control. Unfortunately, ecosystem restoration efforts have not always been a priority for coastal management. This 10-page literature review surveys the available ecosystem-service valuation literature for five of Florida’s coastal natural communities—oyster reefs, beach dunes, mangrove forests, seagrass beds, and salt marshes—to facilitate the quantification of ecosystem services to provide a better measure of the full impact of restoration efforts. Written by Susanna Blair, Carrie Adams, Tom Ankersen, Maia McGuire, and David Kaplan, and published by the UF Department of Sea Grant, January 2015.

Quasi-morphismes et difféomorphismes hamiltoniens

Dans ce travail, nous etudions differents invariants de nature algebrique et dynamique definis sur le groupe des diffeomorphismes hamiltoniens d'une surface fermee orientee. Occasionnellement, nous considererons egalement le groupe des diffeomorphismes hamiltoniens de certaines varietes symplectiques de dimension superieure. Ces invariants peuvent etre vus comme des generalisations du nombre de rotation de Poincare, et des vecteurs de rotations associes aux diffeomorphismes des surfaces. D'autre part, tous ces invariants sont relies a la theorie de la cohomologie bornee. Dans le premier chapitre nous construisons des quasi-morphismes sur le groupe des diffeomorphismes hamiltoniens d'une surface de genre strictement positif, qui sont des homomorphismes en restriction au sous-groupe des diffeomorphismes a support dans un ouvert diffeomorphe a un disque. Ces constructions sont motivees par une question de Entov et Polterovich. Dans le second chapitre nous construisons un quasi-morphisme defini sur le revetement universel du groupe des diffeomorphismes hamiltoniens d'une variete symplectique monotone. Le troisieme chapitre contient quelques resultats concernant les actions preservant l'aire sur les surfaces de reseaux dans les groupes de Lie semi-simples. Dans l'esprit du "programme de Zimmer", nous montrons comment l'existence de nombreux quasi-morphismes, combinee avec des theoremes d'annulation en cohomologie bornee, pourrait etre utile pour exclure l'existence d'actions de reseaux de rang superieur. Le dernier chapitre contient quelques remarques autour de la distance de Hofer.
A Harmonic-Mixing PLL Architecture for Millimeter-Wave Application

A low-noise synthesizer design in the millimeter-wave (mm-wave) range is complicated by the invariably large closed-loop gain and the high operation frequency of the voltage-controlled oscillator (VCO). To overcome these challenges, this work proposes a harmonic-mixing synthesizer system with a 188-dB figure-of-merit mm-wave VCO. The synthesizer extends the bandwidth to 5 MHz, thereby suppressing VCO noise. Importantly, DSM is not amplified by the $f_{\mathrm{ VCO}}/f_{\mathrm{ ref}}$ gain of the system. A prototype employing a 74-MHz reference achieves a −250-dB phase-locked loop (PLL) figure of merit with a measured 88-fs rms jitter.
Translational gaps and opportunities for medical wearables in digital health

A confluence of advances in biosensor technologies, enhancements in health care delivery mechanisms, and improvements in machine learning, together with an increased awareness of remote patient monitoring, has accelerated the impact of digital health across nearly every medical discipline. Medical grade wearables—noninvasive, on-body sensors operating with clinical accuracy—will play an increasingly central role in medicine by providing continuous, cost-effective measurement and interpretation of physiological data relevant to patient status and disease trajectory, both inside and outside of established health care settings. Here, we review current digital health technologies and highlight critical gaps to clinical translation and adoption. Description Medical wearables have considerable opportunities to drive forward digital health but important translational gaps still remain.
The HARPS search for southern extra-solar planets XVII. Six long-period giant planets around BD -1

We report the discovery of six new substellar companions of main-sequence stars, detected by multiple Doppler measurements with the instrument HARPS installed on the ESO 3.6 m telescope, La Silla, Chile. These extrasolar planets orbit the stars BD -17 0063, HD 20868, HD 73267, HD 131664, HD 145377, and HD 153950. The orbital characteristics that reproduce the observed data are presented, as well as the stellar and planetary parameters. Masses of the companions range from 2 to 18 Jupiter masses, and periods range from 100 to 2000 days. The observational data are carefully analysed for activity-induced effects, and we conclude that the observed radial velocity variations are of exoplanetary origin. Of particular interest is the very massive planet (or brown-dwarf companion) orbiting the metal-rich HD 131664 with m2 sini = 18.15 MJup and a 5.34-year orbital period. These new discoveries are consistent with the observed statistical properties of exoplanet samples known so far.
Rice Bug (suggested common name) Leptocorisa acuta (Thunberg) (Insecta: Hemiptera: Alydidae)

Broad-headed bugs belong to a well-known but relatively small family of plant-feeding true bugs, usually seen feeding on the foliage and flowers of leguminous and graminaceous crops. Leptocorisa acuta (Thunberg) can be found on many crop plants in the family Poaceae (grasses), especially rice, and is a reported pest of economic significance in rice-producing countries like India, Australia, and China. This 3-page fact sheet was written by Amelio Chi Serrano, Russell F. Mizell, III, and Morgan A. Byron, and published by the UF Department of Entomology and Nematology, December 2014. (Photo: Lary E.

Two step chromospheric Moreton wave excitation in a blast-wave scenario. A case study: the December 06, 2006 event

We examine the capability of a blast-wave scenario -associated to a coronal flare or to the expansion of CME flanksto reproduce a chromospheric Moreton phenomenon. We also simulate the Moreton event of December 06, 2006 considering both the corona and the chromosphere. To obtain a sufficiently strong coronal shock -able to generate a detectable chromospheric Moreton wavea relatively low magnetic field intensity is required, in comparison with the active region values. Employing reasonable coronal constraints, we show that a flare ignited blast-wave or the expansion of the CME flanks emulated as an instantaneous or a temporal piston model, respectively, are capable to reproduce the observations.
ISPA: Exploiting Intra-SM Parallelism in GPUs via Fine-Grained Resource Management

Emerging GPUs have multiple Streaming Multiprocessors (SM), while each SM is comprised of CUDA Cores and Tensor Cores. While CUDA Cores do the general computation, Tensor Cores are designed to speed up matrix multiplication for deep learning applications. However, a GPU kernel often either uses CUDA Cores or Tensor Cores, leaving the other processing units idle. Although many prior research works have been proposed to co-locate kernels to improve GPU utilization, they cannot leverage the Intra-SM CUDA Core-Tensor Core Parallelism. Specifically, ISPA designs persistent and elastic block to solve the thread slot and shared memory contention between co-located kernels. ISPA also adopts the register allocation method to manage the register contention. These resource management methods are applicable for both white-box kernels and <inline-formula><tex-math notation="LaTeX">$cudnn$</tex-math><alternatives><mml:math><mml:mrow><mml:mi>c</mml:mi><mml:mi>u</mml:mi><mml:mi>d</mml:mi><mml:mi>n</mml:mi><mml:mi>n</mml:mi></mml:mrow></mml:math><inline-graphic xlink:href="chen-ieq1-3214088.gif"/></alternatives></inline-formula> kernels.

Joint MCS Adaptation and RB Allocation in Cellular Networks Based on Deep Reinforcement Learning With Stable Matching

Joint modulation-coding scheme (MCS) adaptation and resource block (RB) allocation is an effective approach to guarantee different quality of service (QoS) requirements of all UEs under dynamic network environments. In this article, we consider a fifth generation (5G) cellular network with time-varying wireless channels, in which the BS serves multiple user equipments (UEs) under limited available RBs. We aim to minimize the total RB consumption subject to the rigorous constraints of each UE's QoS requirement. To attain this objective, this paper puts forth an online learning technique, referred to as integrated Deep Reinforcement learning and stable Matching (DeepRM), in the sense that the MCS adaptation and RB allocation decisions are conducted without acquiring the real-time channel quality indicator (CQI) feedback. DeepRM is a closed-loop framework, where the output of deep reinforcement learning (DRL) is imported into the stable matching to guide optimal RB allocation whilst the output of stable matching is fed into the DRL framework to assist efficient MCS decision-making. Specifically, in DeepRM, we first develop a powerful DRL algorithm, termed as Action-and-Reward Branching Deep Q-network (ARBDQ), by incorporating the action branch architecture into conventional DRL and modifying the traditional deep neural network training mechanism, to perform judicious MCS decisions on different links in parallel. Then, a new many-to-one stable matching algorithm, called adaptive deferred acceptance, is exploited to dynamically adjust the RB quota of each UE in a computationally efficient fashion. Simulation results demonstrate that compared with ACO-HM, OLLA-ADA, and ARBDQ-Random algorithms, DeepRM induces much less RB consumption while guaranteeing the QoS requirements of all UEs in various network scenarios. Furthermore, under miscellaneous QoS requirement, number of UEs, and CQI reporting period setups, DeepRM is more robust than other baselines.
Comparison of Traditional Image Segmentation Methods Applied to Thermograms of Power Substation Equipment

The variation in the thermal state of electrical energy substation equipment is normally associated with natural wear or equipment failure. This can be detected by infrared thermography, but technically it demands a long time to analyze these images. Computational analysis can allow an automated, more agile, and more efficient analysis to detect overheated regions in thermographic images. Therefore, it is necessary to segment the region of interest in the images; however, the results may diverge depending on the technique used. Thus, this article presents the improvement of four different techniques implemented in Python and applied in a substation under real operating conditions for a period of eleven months. The performance of the four methods was compared using eight statistical performance measures, and the efficiency was measured by the runtime. The segmentation results showed that the methods based on a threshold (Otsu and Histogram-Based Threshold) were fast, with processing times of 0.11 to 0.24 s, but caused excessive segmentation, presenting the lowest accuracy (0.160 and 0.444) and precision (0.004 and 0.049, respectively). The clustering-based methods (Cluster K-means and Fuzzy C-means) showed similar results to each other but were more accurate (0.936 to 1.000), more precise (0.965 to 1.000), and slower, with 2.55 and 38.8 s, respectively, compared to the threshold methods. The Fuzzy C-means method obtained the highest values of specificity, accuracy, and precision among the methods under analysis, followed by the Cluster K-means method.
The Theory of Massive Photons

This paper is concerned with the theory on the rest mass of the photon. The equations for the energy of the photon are developed. The theory predicts an equation for the “massive” photoelectric effect similar to the Einstein's original photoelectric effect. This new theory predicts that the value of the black hole's cutoff radius is a function of the frequency of the photons generated inside the black hole. This means that the black hole's event horizon is not a spherical surface but a three-dimensional shell. Because this formulation is not a gravity theory but a theory on massive photons, it cannot predict exactly the same Schwarzchild radius as general relativity. Despite of not being a gravity theory, this theory predicts that, should the equivalent mass of the photon equal its rest mass, the black hole cutoff radius would be equal to the Schwarzchild radius. I am convinced that the full potential of this formulation will be shown when it is used in conjunction with the Proca equations, the standard model and quantum gravity theories.
