Can Corpus Similarity-Based Self-Annotation Assist Information Retrieval? (2014)

The use of external means to annotate corpora to assist in retrieval is gaining research attention. These external means include user provided annotations, use of linkages between documents (eg. the web), use of knowledge bases such as wikipedia, etc. However, for corpora that are internally generated within an enterprise, most of these methods are not readily applicable.

Indirect Air Conditioning Using Water As Refrigerant; Indirect gekoeld ventileren met water als koudemiddel (2007)

Evaporative adiabatic cooling, using water as refrigerant, is one of the oldest existing types of air conditioning. Indirect operating dew point cooling also based on the evaporating of water, relates to new developments which are now entering the market. These systems are characterized by discharging the evaporated moisture towards the open air and extreme low energy consumption. It makes cooling possible where this would hardly be feasible because of energy reasons. These systems are an alternative to the use of F-gases and contribute to the European policy to reduce the emission of CO2. [Dutch] Dit artikel heeft betrekking op indirect werkende dauwpuntkoeling en de daarop gebaseerde uitvoeringsvorm waarbij door het terugvoeren van een deel van de gekoelde lucht naar het natte deel van de koeler een extra adiabatische koeling wordt bereikt. Om een duidelijk beeld te schetsen wordt eerst ingegaan op adiabatische koeling. Het artikel is door ISSO in samenwerking met StatiqCooling opgesteld, als voorstudie op een hog nader samen te stellen ISSO-publicatie.
Preliminary study of motorcycle lanes capacity in Malaysia (2001)

In Malaysia, motorcycles represented more than halves of all registered vehicle population. In addition, motorcyclist contributed almost 70% of all injuries I accidents on Malaysian roads. This alarming figure warrants for some roads safety strategies targeted specifically on motorcyclists. An effective engineering approach to tackle this problem is by segregating these vulnerable roads users from other motorized traffic through the provision of an exclusive motorcycle lane. Prior to constructing an exclusive motorcycle lane, there is a need to understand the parameters involved in capacity analysis used to assess the supply side, quality of flow and also the design life of this facility. In order to comprehend the relative significance of these parameters, data were collected at five spots along the existing motorcycle track of Federal Highway Route 2. The Greenshields’ method and multiple regression technique were then applied to scrutinize the data. The analysis resulted with the development of preliminary models on the relationships between flow, density and mean speed on motorcycle lanes. Further, a simple regression model that relates the saturation flow (capacity) and effective width of motorcycle lane was established.
High suppression of the short-channel effect in ultrathin SOI n-MOSFETs (2003)

High suppression of threshold voltage roll-off and subthreshold slope characteristics have been experimentally shown in ultrathin SOI n-MOSFETs in the 40-135 nm gate length regime, and the effectiveness of an ultrathin SOI layer to prevent the short channel effect was experimentally confirmed.
Development of a New Pulsatile Extracorporeal Life Support Device Incorporating a Dual Pulsatile Blood Pump (2006)

A new pulsatile extracorporeal life support device (ECLS) has been developed, designed to sustain pulsatile blood flow during emergency cardiopulmonary resuscitations and cardiopulmonary operations. This device features two identical pulsatile pumps that operate alternately and can therefore provide blood inflow in a more uniform manner than similar systems featuring a single-pump configuration. In order to confirm the presumed benefits of this newly-developed dual pulsatile pump configuration, we have conducted a series of in vitro experiments designed to compare the properties of the new system with a single pump system, specifically with regard to pump delivery rate and active filling efficiency. Our results reveal that the dual pump configuration can, indeed, deliver a higher flow than can the single-pump system, and exhibits an active filling efficiency superior to that of the single-pump configuration. We performed a series of animal experiments to measure the pulsatility of the dual-pump configuration in terms of equivalent energy pressure (EEP). In order to measure EEP, we measured femoral arterial pressure and pump outflow. The results of our animal experiments revealed that the newly-developed pulstile ECLS exhibits sufficient pulsatility in terms of the EEP considerations.
Time‐temperature superposition principle application to the hygrothermal discoloration of colored high‐density polypropylene/wood composites (2014)

Discoloration kinetics of wood plastic composites (WPCs) made of recycled high density polyethylene (HDPE) during accelerated hygrothermal aging test at 45–65°C was conducted by means of time‐temperature superposition principle (TTSP). Color parameters measured with a spectrophotometer by CIELAB color system showed that L* and Δ E* increased while a* and b* decreased with aging time and temperature. A single horizontal shift was adequate for the superposition of color parameter master curves, indicating temperature can be used as accelerating factor to the discoloration of the studied WPCs. The regression line for Arrhenius plot showed a linearity for color parameters ( R 2 = 0.9996), suggesting TTSP concept can be used to analyze and predict the discoloration kinetics of WPCs at low aging temperature. The prediction of color parameters at ambient aging temperature (21°C) can be extended to 7.2 years. The activation energy calculated from color parameters using TTSP method was 85.5 kJ/mol and similar to the reported values of HDPE thermal relaxation reactions calculated from other methods in the open literature.

Naturwissenschaftliche, ethische und rechtliche Empfehlungen zur klinischen Translation der Forschung mit humanen induzierten pluripotenten Stammzellen und davon abgeleiteten Produkten (2020)

In der öffentlichen Debatte wurden humane induzierte pluripotente Stammzellen (hiPS-Zellen) im Vergleich zu humanen embryonalen Stammzellen (hES-Zellen) oft als moralisch unproblematische Alternative zur verbrauchenden Forschung mit Embryonen dargestellt. Doch bei genauerer Betrachtung wird klar, dass insbesondere die klinische Translation der Forschung mit hiPS-Zellen und davon abgeleiteten Produkten eigene ethische, aber auch naturwissenschaftliche und rechtliche Probleme aufwirft. Im Jahr 2016 hat die International Society for Stem Cell Research (ISSCR) Leitlinien für die klinische Translation der Stammzellforschung veröffentlicht. Diese Leitlinien beziehen sich allerdings nicht exklusiv auf hiPS-Zellen und berücksichtigen ferner nicht die Perspektiven aller beteiligten Stakeholder. Für die Ausgestaltung der klinischen Translation der hiPS-Zell-Forschung ist sowohl die Schaffung geeigneter naturwissenschaftlicher und rechtlicher Rahmenbedingungen als auch angemessener ethischer Vorgaben dringend erforderlich. Der durch das Bundesministerium für Bildung und Forschung geförderte deutsch-österreichische Forschungsverbund „ClinhiPS“ entwickelte zu diesem Zweck die vorliegenden naturwissenschaftlichen, ethischen und rechtlichen Empfehlungen zur klinischen Translation der Forschung mit hiPS-Zellen und davon abgeleiteten Produkten.
Robust Model-free Reinforcement Learning with Multi-objective Bayesian\n Optimization (2019)

In reinforcement learning (RL), an autonomous agent learns to perform complex\ntasks by maximizing an exogenous reward signal while interacting with its\nenvironment. In real-world applications, test conditions may differ\nsubstantially from the training scenario and, therefore, focusing on pure\nreward maximization during training may lead to poor results at test time. In\nthese cases, it is important to trade-off between performance and robustness\nwhile learning a policy. While several results exist for robust, model-based\nRL, the model-free case has not been widely investigated. In this paper, we\ncast the robust, model-free RL problem as a multi-objective optimization\nproblem. To quantify the robustness of a policy, we use delay margin and gain\nmargin, two robustness indicators that are common in control theory. We show\nhow these metrics can be estimated from data in the model-free setting. We use\nmulti-objective Bayesian optimization (MOBO) to solve efficiently this\nexpensive-to-evaluate, multi-objective optimization problem. We show the\nbenefits of our robust formulation both in sim-to-real and pure hardware\nexperiments to balance a Furuta pendulum.\n
Predictive Channel Quantization and Beamformer Design for MIMO-BC with Limited Feedback (2007)

For a cellular system based on frequency division duplexing where the base station (BS) is equipped with multiple antennas and the mobile terminals (MTs) have one antenna each, we propose joint techniques to a) feed back channel state information from MTs to the BS, b) design the beamformer and c) schedule downlink transmissions. We propose that both BS and MT predict channel variations, and the feedback (FB) information from MT to BS is given by the prediction error. For the beamformer design we both consider a zero forcing approach and investigate a new solution based on the minimum mean square error criterion, which takes into account the quantization error. By exploiting the FB information, we derive approximated expressions of the signal to noise ratio relative to each MT, used at BS to perform scheduling with an efficient greedy algorithm. Performance assessment on realistic 3GPP channel models show that the proposed techniques provide a significant improvement of the network throughput at a lower FB rate than existing solutions.
US professional football: The demand for game‐day attendance in 1991 (1994)

Abstract This paper examines the factors which affect game‐day attendance at National Football League games during the 1991 season. Using a Tobit analysis, the model includes economic as well as quality of game variables as explanatory variables. This analysis reveals that: higher ticket prices reduce attendance with the demand appearing to be inelastic; and a winning home team spurs game‐day attendance.
[Selection of advantage prediction model for forest fire occurrence in Tahe, Daxing'an Mountain]. (2014)

This study chose zero-inflated model and Hurdle model that have been widely used in economic and social fields to model the fire occurrence in Tahe, Daxing'an Mountain. The AIC, LR and SSR were used to compare the models including zero-inflated Poisson model (ZIP), zero-inflated negative binomial model (ZINB), Poisson-Hurdle model (PH) and negative Binomial Hurdle (NBH) (two types, four models in total) so as to determine a better-fit model to predict the local fire occurrence. The results illustrated that ZINB model was superior over the other three models (ZIP, PH and NBH) based on the result of AIC and SSR tests. LR test revealed that the negative binomial distribution was suitable to both the "count" portion of zero-inflated model and hurdle model. Furthermore, this paper concluded that the zero-inflated model could better fit the fire feature of the study area according to the hypotheses of the two types of models.
Digital micromirror device as a diffractive reconfigurable optical switch for telecommunication (2013)

Digital micromirror devices (DMDs) by their high-switching speed, stability, and repeatability are promising devices for fast, reconfigurable telecommunication switches. However, their binary mirror orientation is an issue for conventional redirection of a large number of incoming ports to a similarly large number of output fibers, like with analog micro-opto electro-mechanical systems. We are presenting here the use of the DMD as a diffraction-based optical switch, where Fourier diffraction patterns are used to steer the incoming beams to any output configuration. Fourier diffraction patterns are computer-generated holograms that structure the incoming light into any shape in the output plane. This way, the light from any fiber can be redirected to any position in the output plane. The incoming light can also be split to any positions in the output plane. This technique has the potential to make an “any-to-any,” true nonblocking, optical switch with high-port count, solving some of the problems of the present technology.
Tool Use Specific Adult Neurogenesis and Synaptogenesis in Rodent (Octodon degus) Hippocampus (2013)

We previously demonstrated that degus (Octodon degus), which are a species of small caviomorph rodents, could be trained to use a T-shaped rake as a hand tool to expand accessible spaces. To elucidate the neurobiological underpinnings of this higher brain function, we compared this tool use learning task with a simple spatial (radial maze) memory task and investigated the changes that were induced in the hippocampal neural circuits known to subserve spatial perception and learning. With the exposure to an enriched environment in home cage, adult neurogenesis in the dentate gyrus of the hippocampus was augmented by tool use learning, but not radial maze learning, when compared to control conditions. Furthermore, the proportion of new synapses formed in the CA3 region of the hippocampus, the target area for projections of mossy fiber axons emanating from newborn neurons, was specifically increased by tool use learning. Thus, active tool use behavior by rodents, learned through multiple training sessions, requires the hippocampus to generate more novel neurons and synapses than spatial information processing in radial maze learning.
Cassava brown streak disease: a threat to food security in Africa (2015)

Cassava brown streak disease (CBSD) has emerged as the most important viral disease of cassava (Manihot esculenta) in Africa and is a major threat to food security. CBSD is caused by two distinct species of ipomoviruses, Cassava brown streak virus and Ugandan cassava brown streak virus, belonging to the family Potyviridae. Previously, CBSD was reported only from the coastal lowlands of East Africa, but recently it has begun to spread as an epidemic throughout the Great Lakes region of East and Central Africa. This new spread represents a major threat to the cassava-growing regions of West Africa. CBSD-resistant cassava cultivars are being developed through breeding, and transgenic RNA interference-derived field resistance to CBSD has also been demonstrated. This review aims to provide a summary of the most important studies on the aetiology, epidemiology and control of CBSD and to highlight key research areas that need prioritization.
Technical Efforts for Energy-Saving Operation of Linear Metros in Japan (2019)

This paper reply reports the newest technical challenge of energy-saving automatic train operation (ATO) in a Japanese linear metro from 2016 through 2018. Based on the fundamental energy-saving strategy established in the eco-rail project by Japan Subway Association (JSA) from 2013 through 2016 in which possibly long coasting and power-limiting regenerative braking scheme, the authors proposed design of the energy-saving running profile with longer coasting by enhancing powering acceleration and evaluated the energy-saving performance through numerical calculations as well as on-track vehicle tests on a commercial linear metro line in Osaka-City. The reduction of the total traction-energy of six percent in total was confirmed in spite of the worse powering energy loss of linear induction motors according to larger slip frequency for the powering acceleration enhancement.
Electrical Properties of All-Perovskite Oxide (SrRuO3/BaxSr1-xTiO3/SrRuO3) Capacitors (1997)

Thin film capacitors consisting totally of perovskite oxides ( SrRuO 3 /Ba x Sr 1- x TiO 3 (20 nm) / SrRuO 3 ) were fabricated on Si and SrTiO 3 substrates by rf magnetron sputtering. The dielectric constants for polycrystalline and single-crystal epitaxial films were observed to be 274 and 681, respectively. The lowest SiO 2 equivalent thickness for the single-crystal epitaxial capacitor was 0.11 nm. The leakage current density was less than 1×10 -7 A/cm 2 for a bias of ±1.2 V. The electrical properties of all-perovskite oxide capacitors were compared with those of samples with Pt top electrodes, and large differences in the values of the dielectric constant were observed. These are explained in terms of differences in the interface between the dielectric and the top electrode and the possible existence of a low- ε layer at the interface between the Pt top electrode and Ba x Sr 1- x TiO 3 . In addition, the origin of the large difference in the dielectric constants for polycrystalline and single-crystal epitaxial capacitors are discussed in terms of the lattice distortion in Ba x Sr 1- x TiO 3 .
Synthetic Diversity from a Versatile and Radical Nitrating Reagent (2019)

We leverage the slow liberation of nitrogen dioxide from a newly discovered, inexpensive succinimide-derived reagent to allow for the C-H diversification of alkenes and alkynes. Beyond furnishing a library of aryl β-nitroalkenes, this reagent provides unparalleled access to β-nitrohydrins and β-nitroethers. Detailed mechanistic studies strongly suggest that a mesolytic N-N bond fragmentation liberates a nitryl radical. Using in situ photo-sensitized, electron paramagnetic resonance spectroscopy, we observed direct evidence of a nitryl radical in solution by nitrone spin-trapping. To further exhibit versatility of N-nitrosuccinimide under photoredox conditions, the late-stage diversification of an extensive number of C-H partners to prepare isoxazolines and isoxazoles is presented. This approach allows for the formation of an in situ nitrile oxide from a ketone partner, the presence of which is detected by the formation of the corresponding furoxan when conducted in the absence of a dipolarophile. This 1,3-dipolar cycloaddition with nitrile oxides and alkenes or alkynes proceeds in a single-operational step using a mild, regioselective, and general protocol with broad chemoselectivity.

Impact of an anemia clinic on emergency room visits and hospitalizations in patients with anemia of CKD pre-dialysis. (2007)

Enrollment in a dedicated nurse-managed anemia clinic is significantly associated with reduced emergency room visits and hospitalizations in patients with pre-end stage CKD. These associative findings justify future prospective analyses to establish causality.
Standardization of resilience & survivability, and autonomic fault-management, in evolving and future networks: An ongoing initiative recently launched in ETSI (2013)

Resilience and Survivability in networks is an area which is growing fast, mainly due to the fact that these vital desired properties for a network, protocol, application, or service behaviour, are now receiving a lot of attention from industry, research, academia, and standardization groups-thanks to the emergence of autonomic & cognitive management and control paradigms for the evolving networks in recent years. In characterizing the resilience properties of a system or individual functional entities of a system, the area of autonomics is extending the traditional scope and meaning of resilience in networks, by including self-diagnosing and self-repairing/self-healing behaviours, as well as proactive resilience to various types of challenges i.e. adverse conditions of operation and incidents (including fault-activations and security attacks and threats). This goes beyond the protection and restoration techniques for survivable networks found in protocols such as SDH, ATM, and IP-Fast-Re-route. What is becoming crucial for the global community is the establishment of standardized frameworks that can be applied for implementing interoperable systems that exhibit resilience properties in their own capacity and collaboratively as networked systems. This paper reports on a recently launched initiative in ETSI (European Telecommunications Standards Institute) that is aimed at standardizing resilience, survivability, autonomic fault-management and autonomic security management. We outline the types of concepts and architectural principles that are standardizable from resilience, survivability, and autonomic fault and security management point of view. We present and discuss a candidate evolvable architectural framework for standardization that unifies resilience, survivability and autonomic fault-management within a single holistic framework. It unifies the aspects by defining the responsible Functional Blocks (FBs) and their interworking in the realization of resilience, survivability, autonomic fault-management and autonomic security management in systems and networks. We show how research results in these areas can now be contributed to developing and relying on a commonly-shared (i.e. common baseline) unified standardized framework, by adopting, enhancing and evolving the framework presented in this paper as standardization activity (open to all technical experts/researchers to now join).
Cross-domain recommendations without overlapping data (2014)

Cross-domain recommender systems adopt different techniques to transfer learning from source domain to target domain in order to alleviate the sparsity problem and improve accuracy of recommendations. Traditional techniques require the two domains to be linked by shared characteristics associated to either users or items. In collaborative filtering (CF) this happens when the two domains have overlapping users or item (at least partially). Recently, Li et al. [7] introduced codebook transfer (CBT), a cross-domain CF technique based on co-clustering, and presented experimental results showing that CBT is able to transfer knowledge between non-overlapping domains. In this paper, we disprove these results and show that CBT does not transfer knowledge when source and target domains do not overlap.
Normal vs tangential polarizations in metasurfaces (2017)

In this study we categorize metasurfaces with respect to the direction of their polarization currents i.e., either tangential or normal to the metasurface plane. We theoretically investigate whether or not normal polarization currents can add extra degrees of freedom in engineering the reflection and transmission characteristics of functional metasurfaces. We then present a general formalism in which two different metasurface design scenarios with distinct polarization directions perform equally in engineering desired reflection and/or transmission properties. The result of our study provides a valuable tool to choose the most convenient approach in the design of functional metasurfaces.
