Novel method to predict body weight in children based on age and morphological facial features (2014)

A new and novel approach of predicting the body weight of children based on age and morphological facial features using a three-layer feed-forward artificial neural network (ANN) model is reported. The model takes in four parameters, including age-based CDC-inferred median body weight and three facial feature distances measured from digital facial images. In this study, thirty-nine volunteer subjects with age ranging from 6-18 years old and BW ranging from 18.6-96.4 kg were used for model development and validation. The final model has a mean prediction error of 0.48, a mean squared error of 18.43, and a coefficient of correlation of 0.94. The model shows significant improvement in prediction accuracy over several age-based body weight prediction methods. Combining with a facial recognition algorithm that can detect, extract and measure the facial features used in this study, mobile applications that incorporate this body weight prediction method may be developed for clinical investigations where access to scales is limited.

Approximate Formulas for Line Capacitance and Characteristic Impedance of Microstrip Line (1981)

A numerically efficient and accurate method for the derivation of line capacitance and characteristic impedance of a thin microstrip line is discussed. Galerkin's method is found to give highly accurate results when only one or two basis functions are used. We use three methods to derive approximate formulas for microstrip line capacitance and characteristic impedance. Asymptotic lower bounds derived through the variational method and matched asymptotic expansion methods give expressions which reveal the functional forms of these approximate formulas. Seminumerical approximation gives rise to formulas usable on a desk calculator. It is found that there is excellent agreement between the seminumerical formulas, the asymptotic formula derived through matched asymptotic expansions and numerically derived results.
Hardening extended memory access control schemes with self-verified address spaces (2017)

In this paper we revisit the security properties of extended access control schemes that are used to protect application secrets from untrusted system software. We demonstrate the vulnerability of several recent proposals to a class of attacks we call mapping attacks. We argue that protection from such attacks requires verification of the address space integrity and propose the concept of self-verified address spaces (SVAS), where the applications themselves are made aware of the requested changes in the page mappings and are placed in charge of verifying them. SVAS equips an application with a customized verification model with several attractive functional and performance properties. We implemented the attacks and a complete prototype of SVAS in Linux and the QEMU emulator. Our results demonstrate that SVAS can prevent mapping attacks on extended access control systems with minimal performance overhead, hardware modifications and software complexity.

Significance Messages: An Integrated Display Concept (1988)

This paper describes one integral display concept — Significance Messages — which communicates the significance of a numerical value of some continuous parameter. The Significance Messages System combines a variety of kinds of raw data using software techniques from artificial intelligence in order to build a qualitative scale that communicates what a numeric value of some parameter means about the state of the application world given the current context. The Significance Messages concept is built as a generic “shell” that knows about different kinds of qualitative states, contextual factors, and heuristics to focus on relevant data. The designer enters domain specific, parameter specific knowledge about alarm setpoints, automatic system setpoints, etc. and about the specific contextual factors that are relevant to the interpretation of that parameter in order to create a particular Significance Message Display for a particular application.
Movimiento vecinal y cultura política democrática en castilla y león. El caso de valladolid (1964-1986) (2011)

Esta Tesis supone rescatar para la historiografia contemporanea espanola un colectivo tan importante como obviado por los historiadores: las asociaciones de vecinos.
 Son bastantes los trabajos y en general de muy reciente aparicion, que se refieren someramente al papel crucial del tejido asociativo vecinal en la caida del entramado franquista y consolidacion del modelo democratico actual, pero nunca se ha abordado a fondo la cuestion. ?Hasta que punto las asociaciones de vecinos ayudaron al establecimiento de unas nuevas pautas democraticas? Esta tesis intenta responder a esta cuestion y a otras muchas.
 Respecto a los contenidos, resulta una interesante historia comparada de Castilla y Leon, al estudiar sus capitales de provincia, descubriendo en cuales se desarrollo plenamente el movimiento asociativo vecinal, cuales fueron sus recursos, cuales sus metodos, exitos y fracasos, etc. Ademas esa comparacion se hace extensiva a casos nacionales, como son el del propio Madrid o Barcelona. La tesis, obviamente, analiza de forma exhaustiva al movimiento asociativo vecinal castellano y leones, centrandose en el mas fuerte de ellos, el vallisoletano, determinando sus inicios, composicion, metodos, reivindicaciones, logros, etc.
Junto a esto, sus relaciones con otros movimientos, desde las administraciones locales a los partidos politicos opositores pasando por los principales agentes de la contestacion al franquismo: la Iglesia (con el fenomeno de los curas obreros), el movimiento obrero y el estudiantil. Movimientos que siguen a veces caminos paralelos y otras es imposible separar, pues muchas de las gentes que destaquen en el ambito vecinal, descollaran tambien en el obrero, politico, etc.
 La meta final de la tesis es dilucidar la aportacion de las asociaciones de vecinos de Valladolid a la cultura politica de la Transicion; como y hasta que punto ayudaron o participaron en el cambio de una sociedad desmovilizada a otra activa y vigilante para con sus derechos de ciudadania, desentranando su pasado y perfilando su futuro.
Application of Radial Ray Based Segmentation to Cervical Lymph Nodes in CT Images (2013)

The 3D-segmentation of lymph nodes in computed tomography images is required for staging and disease progression monitoring. Major challenges are shape and size variance, as well as low contrast, image noise, and pathologies. In this paper, radial ray based segmentation is applied to lymph nodes. From a seed point, rays are cast into all directions and an optimization technique determines a radius for each ray based on image appearance and shape knowledge. Lymph node specific appearance cost functions are introduced and their optimal parameters are determined. For the first time, the resulting segmentation accuracy of different appearance cost functions and optimization strategies is compared. Further contributions are extensions to reduce the dependency on the seed point, to support a larger variety of shapes, and to enable interaction. The best results are obtained using graph-cut on a combination of the direction weighted image gradient and accumulated intensities outside a predefined intensity range. Evaluation on 100 lymph nodes shows that with an average symmetric surface distance of 0.41 mm the segmentation accuracy is close to manual segmentation and outperforms existing radial ray and model based methods. The method's inter-observer-variability of 5.9% for volume assessment is lower than the 15.9% obtained using manual segmentation.
B119 Boiling Heat Transfer and Flow Patterns in a Narrow Vertical Annulus (2001)

Experiments of flow boiling of water at 0.11MPa were conducted in a vertical narrow annulus for the inlet subcooling of 10 to 50 K and mass velocity of 100 to 750 kg/m^2s. Measured boiling curves show existence of enhancement regions of heat transfer. Visual observation identified flow patterns peculiar to narrow space. Isolated bubbles generated at lower heat fluxes are deformed and spread rapidly over the whole narrow annulus. At higher heat fluxes, the narrow space are filled with vapor mass and dry patches are seen on the heating tube Flow patterns are different from those in conventional large tubes
Non-impact printer power and motor control system on a chip (2002)

An integrated circuit chip set has been developed that realizes a color nonimpact printer power supply and motor control system. The two ICs include three switch mode PWM controllers, two unipolar stepper motor drivers, a DC motor H-bridge, a serial control port, and a host of peripheral system functions. Focus is placed on power management and how individual circuits are customized to minimize on-chip power dissipation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Current and Promising Pharmacotherapies, and Novel Research Target Areas in the Treatment of Alcohol Dependence: A Review (2011)

Harmful alcohol use is a risk factor in more than 60 diseases and injuries resulting in approximately 2.5 million deaths per year worldwide. In the United States (US) and Europe, there are only a few medications approved for alcohol dependence (AD) however, these medications have only been moderately effective and there is a crucial need for more effective treatments. This review briefly summarizes research on currently approved medications for AD, as well as promising medications like topiramate, baclofen and ondansetron. Topiramate is likely the most promising new treatment for AD, however, further research is needed to determine the optimal dose and appropriate length of treatment. Baclofen, a GABA(B) agonist, is a promising medication as a treatment for AD, especially for patients with AD and severe liver disease. Ondansetron has shown promising results as a potential medication for AD, but only within a certain subtype of individuals. This review also discusses more recent findings on other potential pharmacotherapies for AD, such as serotonin-specific reuptake inhibitors (SSRIs; i.e. sertraline), aripiprazole and prazosin, as well as on some examples of other potentially interesting new neuropharmacological targets (i.e. cannabinoid receptors, CRF, NPY, ghrelin). Finally, the present review also discusses the attempts to personalize medication for AD treatment by alcohol typology and pharmacogenetics.

Adsorption and diffusion of CO2 in CPO-27–Ni beads (2019)

The present work involves the scale-up and characterization of CPO-27–Ni metal organic framework using a range of experimental techniques aimed at determining equilibrium and kinetic parameters to assess its potential for post-combustion carbon capture. CPO-27–Ni was prepared from its precursors by molecular gastronomy methods in kilogram scale. Adsorption of isotherms of pure CO2 and N2 were obtained for different temperatures on these beads, using a volumetric apparatus and the isotherms were fitted to a dual-site Langmuir model. A series of experiments were then carried out in the volumetric apparatus by dosing a known volume of CO2 and the pressure was monitored with time. The diffusional time constants were then extracted by fitting the series of curves to an isothermal diffusion model. From the time constants, the values of the diffusivities were obtained and compared with the values obtained from first principles correlations, which employed the pore size, and the porosity values from independent mercury porosimetry experiments. The results from the analysis showed that the transport of CO2 in the beads was well described by a combination of Knudsen and viscous diffusion mechanisms. Experiments were also carried out using a zero-length column (ZLC) apparatus by preparing a 10% CO2–He and 10% CO2–N2 mixture. The analysis of the ZLC curves showed that the two different carrier gases had an effect of the long-time slope, indicating the presence of a macropore-controlled diffusion mechanism.
Learning latent representations of nodes for classifying in heterogeneous social networks (2014)

Social networks are heterogeneous systems composed of different types of nodes (e.g. users, content, groups, etc.) and relations (e.g. social or similarity relations). While learning and performing inference on homogeneous networks have motivated a large amount of research, few work exists on heterogeneous networks and there are open and challenging issues for existing methods that were previously developed for homogeneous networks. We address here the specific problem of nodes classification and tagging in heterogeneous social networks, where different types of nodes are considered, each type with its own label or tag set. We propose a new method for learning node representations onto a latent space, common to all the different node types. Inference is then performed in this latent space. In this framework, two nodes connected in the network will tend to share similar representations regardless of their types. This allows bypassing limitations of the methods based on direct extensions of homogenous frameworks and exploiting the dependencies and correlations between the different node types. The proposed method is tested on two representative datasets and compared to state-of-the-art methods and to baselines.
The secret life of CFTR as a calcium‐activated chloride channel (2013)

cAMP-stimulated anion conductance is defective in cystic fibrosis (CF). The regulatory domain of CFTR, the anion channel protein encoded by the CF gene, possesses an unusually high density of consensus sequences for phosphorylation by protein kinase A (14 in a stretch of <200 amino acids). Thus it is not surprising that CFTR is viewed primarily as a cAMP-stimulated anion channel, and most studies have focused on this mode of activation. However, there is growing evidence that CFTR also responds to Ca(2+)-mobilizing secretagogues and contributes substantially to cholinergic and purinergic responses in native tissues. G protein-coupled receptors that signal through Gαq can stimulate CFTR channels by activating Ca(2+)-dependent adenylyl cyclase and tyrosine kinases, and also by inhibiting protein phosphatase type 2A. Here we review evidence for these novel mechanisms of CFTR activation and discuss how they may help explain previous observations.
Multivalent Aptamer‐Functionalized Single‐Strand RNA Origami as Effective, Target‐Specific Anticoagulants with Corresponding Reversal Agents (2021)

Anticoagulants are commonly utilized during surgeries and to treat thrombotic diseases like stroke and deep vein thrombosis. However, conventional anticoagulants have serious side-effects, narrow therapeutic windows, and lack safe reversal agents (antidotes). Here, an alternative RNA origami displaying RNA aptamers as target-specific anticoagulant is described. Improved design and construction techniques for self-folding, single-molecule RNA origami as a platform for displaying pre-selected RNA aptamers with precise orientational and spatial control are reported. Nuclease resistance is added using 2'-fluoro-modified pyrimidines during in vitro transcription. When four aptamers are displayed on the RNA origami platform, the measured thrombin inhibition and anticoagulation activity is higher than observed for free aptamers, ssRNA-linked RNA aptamers, and RNA origami displaying fewer aptamers. Importantly, thrombin inhibition is immediately switched off by addition of specific reversal agents. Results for single-stranded DNA (ssDNA) and single-stranded peptide nucleic acid (PNA) antidotes show restoration of 63% and 95% coagulation activity, respectively. To demonstrate potential for practical, long-term storage for clinical use, RNA origami is freeze-dried, and stored at room temperature. Freshly produced and freeze-dried RNA show identical levels of activity in coagulation assays. Compared to current commercial intravenous anticoagulants, RNA origami-based molecules show promise as safer alternatives with rapid activity switching for future therapeutic applications.
Using conduction modes basis functions for efficient electromagnetic analysis of on-chip and off-chip interconnect (2002)

In this paper, we present an efficient method to model the interior of the conductors in a quasi-static or full-wave integral equation solver. We show how interconnect cross-sectional current distributions can be modeled using a small number of conduction modes as basis functions for the discretization of the mixed potential integral equation (MPIE). Two examples are presented to demonstrate the computational attractiveness of our method. In particular, we show how our new approach can successfully and efficiently capture skin effects, proximity effects and transmission line resonances.
Evaluation of a recycling bioreactor for biosurfactant production by <i>Pseudomonas aeruginosa</i><scp>MR01</scp> using soybean oil waste (2015)

BACKGROUND This study deals with the large‐scale production of biosurfactant from soybean oil soapstock by Pseudomonas aeruginosa MR01 . The production of biosurfactant was carried out in a newly designed bioreactor equipped with recycling flow under three operational conditions. Kinetic studies were conducted at both shake flask and 5‐L bioreactor scales during fermentation in a soapstock medium. Mathematical equations were developed to model the kinetic patterns at both scales. RESULT Statistical analyses demonstrated the goodness of fit, with regression r‐squared, R 2 , between 0.97and 0.99 for different models. Furthermore, biosurfactant concentration in the bioreactor including the recycling flow, which was switched on and off during a 6‐h period, reached 25.5 g L −1 ( Y P /S =0.9) which showed 41.5% and 21.5% growth compared with experiments conducted in a shake flask and a non‐recycling‐flow bioreactor, respectively. Moreover, the crude biosurfactant at a concentration of 24 mg L −1 was observed to have lowered the surface tension of double‐distilled water from 72 mN m −1 to 28.5 mN m −1 and displayed an emulsification index ( E24 ) of 63% against kerosene. CONCLUSION The results showed the recycling‐flow bioreactor to be a feasible model for further large‐scale studies of biosurfactants. © 2015 Society of Chemical Industry
Development of Universal Breakaway Steel Post for Bullnose Median Barrier (2012)

A new fracturing-bolt universal breakaway steel post (UBSP) was developed and evaluated for use as a replacement for the controlled-release terminal (CRT) wood post currently used in the Thrie beam bullnose system. After numerous steel post concepts were investigated, a fracturing-bolt steel post was selected as the most promising design. The fracturing-bolt steel post successfully matched the strength and dynamic behavior of the CRT wood post in three impact orientations. The UBSP was incorporated into the Thrie beam bullnose barrier system and subjected to three full-scale vehicle crash tests according to the Test Level 3 guidelines provided in NCHRP Report 350. Test Designations 3–30, 3–31, and 3–38 were chosen to evaluate the performance of the Thrie beam bullnose system with UBSPs. All three full-scale crash tests demonstrated that the UBSP performed in a satisfactory manner in the bullnose system, as the vehicle was captured and safely brought to a controlled stop. On the basis of the successful completion of the three full-scale crash tests, it is recommended that the UBSP be considered a safe alternative to CRT posts in the original Thrie beam bullnose median barrier system. It is also noted that the performance of the UBSP suggests that it may have additional applications, including in long-span guardrail, end terminals, and guardrail in mow strips or encased in pavement.
The Fog of Numbers (2020)

In times of economic turbulence, revisions to GDP data can be sizable, which makes conducting economic policy in real time during a crisis more difficult. A simple model based on Okun’s law can help refine the advance data release of real GDP growth to provide an improved reading of economic activity in real time. Applying this to data from the Great Recession explains some of the massive GDP revisions at that time. This could provide a guide for possible revisions to GDP releases during the current coronavirus crisis.
