A flexible and portable harvesting-storage device by quasi-solid-state supercapacitor and dye-sensitized solar cell integration (2017)

In recent years the utilization of power in off grid conditions is dramatically increasing. For this reason research is putting much effort in obtaining improvements in energy storage devices efficiencies and in discovering alternatives concerning easiness of fabrication that can be industrially implemented. In this framework, integration of energy storage devices with energy harvesting systems is obtaining more and more significance since the amount of energy that can be stored especially in Electrochemical Double Layer Capacitors (EDLCs) is limited. To this purpose, herein we present an innovative flexible integrated device composed by a symmetrical aqueous EDLC and a TiO2 nanotubes-based Dye Sensitized Solar cell (DSSC). A UV photo-polymerized quasi-solid electrolyte was used in both sections. At first a self-standing flexible polymer matrix was fabricated starting from Bisphenol A ethoxylate dimethacrylate (BEMA) and poly (ethylene glycol) methyl ether methacrylate (PEGMA), adding a 3% by weight of 2hydroxy-2-methyl-1-phenyl-1-propanone (Darocur 1173) as photoinitiator. Then, the matrix was soaked in two different liquid electrolytes, a 2 M NaCl aqueous solution for the energy storage section and an Iodine-based liquid electrolyte for the DSSC unit. This is the first work in which this type of polymer electrolyte membrane is used for an EDLC. The electrodes were fabricated onto Stainless-steel and Titanium grids, for EDLC and DSSC respectively. TiO2 nanotubes were grown by means of anodic oxidation as photoanode semiconductor material, while EDLC active material was composed by 85% of graphene nanoplatelets and 15% of Acetylene Black. The harvesting-storage device (HSD) was sealed by a light-cured photo-polymerization method. The measured overall photon-to-electrical conversion and storage efficiency for the HSD was 1.02% under standard test conditions. This value increases for lower illumination conditions reaching 1.46% at 0.3 Sun.
Designing of portlet-based web portals (2008)

Diversas fuentes establecen que 'el 80% del exito de un proyecto de portal depende de la calidad de su diseno ', Es por ello que esta tesis ha tenido como objetivo hacer una propuesta de un metodo para el diseno de portales Web, especificamente aquellos que son integradores de portlets. El enfoque ha sido considerar al portal Web como una agregacion funcional o de servicios, y no una mera agregacion de paginas html. La funcionalidad, los servicios se ofreceran por medio de portlets Un portlet es una aplicacion interactiva, con interfaz de usuario incluida, que puede ser ofrecida a traves de una aplicacion Web.

Concretamente, se hace una propuesta basada en MDD (model-driven development). Se propone disenar los portales Web utilizando tres puntos de vista: las tareas que ofrecen, su orquestacion y su visualizacion. Para ello se ha disenado un metamodelo, SOP, con tres modulos, TASK, ORCHESTRATION y RENDERING, uno para cada perspectiva. Asi, el resultado del diseno de un portal Web sera un statechart (i.e., diagrama de transicion de estados), anotado con descripcion de la visualizacion. Ademas se ha descrito el proceso para la generacion automatica del codigo del portal Web a partir del diseno: se ha implementado la transformacion de este modelo independiente de la plataforma (SOP), en otro modelo dependiente de la plataforma, concretamente la plataforma eXo. 

Por otra parte, actualmente, practicamente la agregacion de portlets se limita a una de tipo side-by-side, donde los portlets se colocan uno junto al otro, de manera 'aislada'. Si varios portlets utilizan los mismos datos, o los datos obtenidos en uno se necesitan en otro, sera el propio usuario quien tendra que repetir la introduccion de los mismos. Con el objetivo de mejorar la usabilidad de los portales Web, esta tesis hace una segunda propuesta. Se basa en anotaciones semanticas de los portlets y los portales (definiendo los conceptos de ontologias de portlet y portal). La propuesta planteada es integrar las ontologias durante el diseno del portal Web y ademas definir reglas de inferencia para especificar la relacion entre conceptos. Estas reglas de inferencia y las instancias de las ontologias correspondientes se utilizaran para intercambiar datos entre los portlets, el propio portal sera el mediador.
The nesC language (2014)

We present nesC, a programming language for networked embedded systems that represent a new design space for application developers. An example of a networked embedded system is a sensor network, which consists of (potentially) thousands of tiny, lowpower "motes," each of which execute concurrent, reactive programs that must operate with severe memory and power constraints. nesC's contribution is to support the special needs of this domain by exposing a programming model that incorporates event-driven execution, a flexible concurrency model, and component-oriented application design. Restrictions on the programming model allow the nesC compiler to perform whole-program analyses, including data-race detection (which improves reliability) and aggressive function inlining (which reduces resource consumption). nesC has been used to implement TinyOS, a small operating system for sensor networks, as well as several significant sensor applications. nesC and TinyOS have been adopted by a large number of sensor network research groups, and our experience and evaluation of the language shows that it is effective at supporting the complex, concurrent programming style demanded by this new class of deeply networked systems.
Generalisable and distinctive 3D local deep descriptors for point cloud registration. (2021)

An effective 3D descriptor should be invariant to different geometric transformations, such as scale and rotation, repeatable in the case of occlusions and clutter, and generalisable in different contexts when data is captured with different sensors. We present a simple but yet effective method to learn generalisable and distinctive 3D local descriptors that can be used to register point clouds captured in different contexts with different sensors. Point cloud patches are extracted, canonicalised with respect to their local reference frame, and encoded into scale and rotation-invariant compact descriptors by a point permutation-invariant deep neural network. Our descriptors can effectively generalise across sensor modalities from locally and randomly sampled points. We evaluate and compare our descriptors with alternative handcrafted and deep learning-based descriptors on several indoor and outdoor datasets reconstructed using both RGBD sensors and laser scanners. Our descriptors outperform most recent descriptors by a large margin in terms of generalisation, and become the state of the art also in benchmarks where training and testing are performed in the same scenarios.
Out of the frying pan into the fire: the limits of loan finance in a capital subsidy context (2001)

This paper describes the difficulties that the South African Homeless People’s Federation has had to face, as the government housing subsidies to which its members are entitled have not been forthcoming. The Federation’s members are entitled to a housing subsidy of around US$ 1,500 - and there are housing developments all over South Africa built by Federation savings and loan groups that have demonstrated their capacity to build good quality homes with this. Because of the time taken to obtain housing subsidies, a special fund (the uTshani Fund) was set up to provide bridging loans so that members could start building their own homes. The Fund was to be sustained, as members obtained housing subsidies and repaid the loan thus making more funds available for other bridging loans. But most members who took out loans never received the subsidy and many now face difficulties in repaying these loans. This paper describes how the problem arose and how the Federation and its support NGO, People’s Dialogue on Land and Shelter, are seeking to address it. In doing so, it discusses the difficulties that movements of the urban poor face in reconciling the immediate needs of members (including access to housing) with strategies to obtain the long-term political changes that would allow such needs to be met sustainably.
Research on Power Flow Algorithm of LCC and VSC Hybrid Multi-Terminal AC-DC System (2018)

LCC and VSC are essentially different in the steady-state model and working principle. When the two converters are mixed and applied to the same multi-terminal HVDC transmission system, the steady-state mathematical model and the power flow calculation method have also changed accordingly. This paper first describes the steady-state model of the hybrid system. Then, based on the comprehensive consideration of the working principle and control mode of the two converters, the mathematical model of the power flow calculation of the hybrid system is derived. Furthermore, an alternating solution algorithm suitable for the hybrid system is proposed. Finally, the effectiveness and accuracy of the proposed algorithm are verified by a hybrid two-terminal DC transmission system and a hybrid three-terminal system.
Comparative Evaluation of Antipyretic Activity of Ibuprofen and Aspirin in Children with Pyrexia of Varied Aetiology (1984)

The antipyretic activity of ibuprofen and aspirin was compared in sixteen children with pyrexia due to upper respiratory tract infection and in twelve with fever due to other causes. All 28 children received ibuprofen (7 mg/kg of body-weight) and aspirin (15 mg/kg of body-weight) in a single dose on 2 consecutive days in a crossover manner. Rectal temperature was recorded prior to and at regular intervals up to 8 hours after drug administration. Analysis of the results indicate that ibuprofen and aspirin effectively lower temperature and the two drugs are comparable in their antipyretic activity. In conclusion, significant antipyretic activity, good tolerance profile and availability in syrup form make ibuprofen a useful substitute for aspirin in children with fever.
Studies in Xanthone chemistry (1993)

A series of 3,4-dihydro-9H-xanthen- 1 ,9(2H)-diones has been prepared by the condensation of 2-fluorobenzoyl chlorides with cyclohexane- I ,3-diones followed by Fries rearrangement and cyclisation of the intermediate 3-oxocyclohexenyl&#13;\n2-fluorobenzoates.&#13;\nConversion to spim[ 1 ,2,3,4-tetrahydro-9H-xanthen- 1 ,2'-[ 1 ,3] -dioxolane] -9-one occurred on treatment of the xanthendione with ethane- 1 ,2-diol and trimethylsilyl chloride. 3,4-Dihydro-4-methyl-9H-xanthen- 1 ,9(2H)-dione has been synthesised by quenching the lithium dienolate of the ketal with iodomethane.&#13;\nConjugate reduction of the xanthendione has been accomplished using sodium borohydride in pyridine to give 1hydroxy-2,3,4,4a-tetrahydro-9H-Xanthen-9-one whose chemistry has been investigated.&#13;\nTreatment of the xanthendione with tris(methylthio)methyllithium gave the 1,4-adduct. Subsequent mercuric ion catalysed solvolysis provided methyl 1 -hydroxy-2,3,4,4a-tetrahydro-9H-xanthen-9-one-4a-carboxylate which is the parent nng of the&#13;\nsecalonic acid series of natural products.&#13;\n4a-Alkyl derivatives have been prepared in excellent yield from the xanthendione and organocyanocuprate reagents. The corresponding Grignard reagents displayed less selectivity in their mode of addition.&#13;\nReaction of the 1 -hydroxytetrahydroxanthones with hydroxylamine gave 4-substituted 6,7-dihydro-3-(2-hydroxyphenyl)-2, I -benzisoxazoles resulting from ring cleavage of the xanthone nucleus. Dehydrogenation of these systems with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone and with palladium on charcoal catalyst has been explored.&#13;\nTreatment of 1 -hydroxy-2,3,4,4a-tetrahydro-9H-xanthen-9-ones with lithium diisopropylamide in tetrahydrofuran afforded dianions which provided an entry to 2-functionalised derivatives by quenching with electrophiles.&#13;\nAcid catalysed treatment of 1hydroxy2,3,4,4a-tetrahydro-9H-xanthen-9-One gave 3,4-dihydro-9H-xanthen-9-one by way of a retro-Michael ring cleavage-bond switch operation. The substituted analogues behaved similarly, although the products were&#13;\ndependent upon the nature of the substituents present.&#13;\nThe value of some 3,4-dihydro-9H-xanthen-9-ones as dienes in [4+21-cycloaddition reactions has been established with a variety of dienophiles.&#13;\nThe chemistry of some 2-(2-fluorobenzoyl)- I -hydroxy-2,3,4,4a-tetrahydroxanthones has been investigated. Treatment with DBU in toluene led to 4-(2-hydroxybenzoyl)- 9H-xanthen-9-ones, whereas with potassium carbonate in acetone novel 5H,13H-[l]benzopyrano[2,3 -ajxanthen -5, 1 3-diones were obtained. The mechanism of formation for these compounds is discussed.

Nonreciprocal transport in gate-induced polar superconductor SrTiO 3 (2020)

Polar conductors/superconductors with Rashba-type spin-orbit interaction are potential material platforms for quantum transport and spintronic functionalities. One of their inherent properties is the nonreciprocal transport, where the rightward and leftward currents become inequivalent, reflecting spatial inversion/time-reversal symmetry breaking. Such a rectification effect originating from the polar symmetry has been recently observed at interfaces or bulk Rashba semiconductors, while its mechanism in a polar superconductor remains elusive. Here, we report the nonreciprocal transport in gate-induced two-dimensional superconductor SrTiO<sub>3</sub>, which is a Rashba superconductor candidate. In addition to the gigantic enhancement of nonreciprocal signals in the superconducting fluctuation region, we found kink and sharp peak structures around critical temperatures, which reflect the crossover behavior from the paraconductivity origin to the vortex origin, based on a microscopic theory. The present result proves that the nonreciprocal transport is a powerful tool for investigating the interfacial/polar superconductors without inversion symmetry, where rich exotic features are theoretically prognosticated.
Altered Expression of SPINDLY Affects Gibberellin Response and Plant Development (2001)

Gibberellins (GAs) are plant hormones with diverse roles in plant growth and development. SPINDLY (SPY) is one of several genes identified in Arabidopsis that are involved in GA response and it is thought to encode an O-GlcNAc transferase. Genetic analysis suggests that SPY negatively regulates GA response. To test the hypothesis that SPY acts specifically as a negatively acting component of GA signal transduction, spy mutants and plants containing a 35S:SPY construct have been examined. A detailed investigation of the spy mutant phenotype suggests that SPY may play a role in plant development beyond its role in GA signaling. Consistent with this suggestion, the analysis of spy er plants suggests that the ERECTA (ER) gene, which has not been implicated as having a role in GA signaling, appears to enhance the non-GA spy mutant phenotypes. Arabidopsis plants containing a 35S:SPY construct possess reduced GA response at seed germination, but also possess phenotypes consistent with increased GA response, although not identical to spy mutants, during later vegetative and reproductive development. Based on these results, the hypothesis that SPY is specific for GA signaling is rejected. Instead, it is proposed that SPY is a negative regulator of GA response that has additional roles in plant development.
Multi-carrier DS-CDMA using frequency spread coding (2003)

A multi-carrier direct sequence code division multiple access (MC-DS-CDMA) system combined with frequency spread coding is proposed and investigated for the downlink. The proposed system exploits frequency diversity without additional redundancy by using frequency spread coding in a frequency-selective fading channel. Computer simulation results show its effectiveness in terms of average bit error rate and bandwidth efficiency. Furthermore, the proposed system is compared with a multi-carrier (MC)-CDMA system and a single-carrier (SC)-DS-CDMA system using a RAKE receiver.
Abstract 18995: Statins in Familial Hypercholesterolemia - Effects on Coronary Artery Disease and All-cause Mortality (2015)

Introduction: Heterozygous familial hypercholesterolemia (heFH) is characterized by high levels of low-density lipoprotein cholesterol (LDL-C) and increased risk for premature coronary artery disease (CAD) and death. Reduction of CAD and mortality by statins has not been properly quantified in heFH. The aim of the current study is to determine the effect of statins on CAD and mortality in heFH. Methods: All adult heFH patients identified by the Dutch FH screening program between 1994 and 2014 and registered in the PHARMO Database Network were eligible. Of these patients we obtained hospital, pharmacy (in- and outpatient), and mortality records in the period between 1995 and 2015. The effect of statins (time-varying) on CAD and all-cause mortality was determined using a Cox proportional hazard model, while correcting for the use of other lipid-lowering therapy, thrombocyte aggregation inhibitors, antihypertensive and antidiabetic medication (all time-varying). Furthermore, we used inverse probability for treatment weighting (IPTW) to account for differences between statin-treated and untreated patients regarding history of CAD before follow-up, age at start of follow-up and age of screening, as well as body mass index, LDL-C and triglycerides. Results: Of the 25,479 identified heFH patients, 11,021 gave informed consent to obtain their medical records, of whom 2,447 could be retrieved. We excluded 766 patients younger than 18. The remaining 1,681 heFH patients comprised our study population and these had very similar characteristics as compared to the 23,798 excluded FH patients, e.g. mean (SD) LDL-C levels were 214 (74) vs. 203 (77) mg/dL. Among 1,151 statin users, there were 133 CAD events and 15 deaths during 10,115 statin treated person-years, compared to 17 CAD events and 9 deaths during 4,965 person-years in 530 never statin users (combined rate: 14.6 vs. 5.2, respectively, p&lt;0.001). After applying IPTW to account for indication bias and correcting for use of other medications, the hazard ratio of statin use for CAD and all-cause mortality was 0.61 (0.40 - 0.93). Conclusions: In heFH patients, statins lower the risk for CAD and mortality by 39%.
Monolithic integration of a double heterostructure light-emitting diode and a field-effect transistor amplifier using molecular beam grown AlGaAs/GaAs (1983)

A surface emitting AlGaAs/GaAs double heterostructure light-emitting diode (LED) and an amplifier composed of three GaAs field-effect transistors have been first integrated on a single GaAs substrate. Molecular beam epitaxy has been extensively used to grow a six-layer heterostructure involving a high resistivity AlGaAs layer for electronic isolation. Input voltage to output optical power transfer characteristics are presented. It has also been shown that this integrated device successfully operates at the speed limited by the LED rise time, 7 ns in the present case.
Apolipoprotein E ε4 Allele and Lorazepam Effects on Memory in High-Functioning Older Adults (2005)

In cognitively intact, older adults, the effect of the APOE epsilon4 allele is not necessarily seen in the immediate response to benzodiazepine challenge. Rather, the APOE epsilon4 allele appears to affect the carrier's ability to recover from a cognitive challenge in a normal fashion, at least in a subgroup of subjects with relatively low baseline performance. This suggests that although carrying an APOE epsilon4 allele increases the risk for cognitive toxic effects, allele status alone is not a sufficient predictor of such effects. Studying the response to and the recovery from cognitive challenges may provide insights into the role of the APOE epsilon4 allele and its interaction with other factors in the development of Alzheimer disease and other age-related cognitive problems.
Alpha1-antitrypsin deficiency: forgotten etiology. (2010)

ESTIMATION OF BENDING RIGIDITY AND STRESS CONCENTRATION OF CIRCULAR HOLE VOID SLAB (2002)

Investigation on circular hole Void slab is executed to reduce the slab weight, in which cylindrical steel pipes or other materials are embedded in the center part of cross section in one direction. In this paper, the characteristics of the bending rigidity of the void slab and stress concentrations are confirmed and clarified by direct numerical method. The coefficients of bending rigidity in both directions and of stress concentrations are obtained in accordance with void diameter-thickness ratio. The purpose of this paper is in obtaining the basic design data. This numerical analysis is within the linear theory, and the yield or the limit strength and the final deformation states not evaluated.
Growth of GaN single crystals by a Ca- and Ba-added Na flux method (2011)

GaN substrates are desirable for fabricating ultra-violet LEDs and LDs, and high-power and high-frequency transistors. High-quality GaN single crystals can be obtained by using Na flux method, but the growth habit of bulk crystals must be controlled. In this study, we investigated the effects of additives (Ca, Ba) on the growth habit and impurity concentration in the crystals. The aspect ratio (c/a) of the crystals was increased by increasing the amount of additives, showing that the growth habit could be changed from the pyramidal shape to the prism shape. Ba concentration was below the detection limit (1x10<sup>15</sup> atoms/cm<sup>3</sup>).
