Search Engine Evaluation based on Search Engine Switching Prediction (2015)

In this paper we present a novel application of the search engine switching prediction model for online evaluation. We propose a new metric pSwitch for A/B-testing, which allows us to evaluate the quality of search engines in different aspects such as the quality of the user interface and the quality of the ranking function. pSwitch is a search session-level metric, which relies on the predicted probability that the session contains a switch to another search engine and reflects the degree of the failure of the session. We demonstrate the effectiveness and validity of pSwitch using A/B-testing experiments with real users of search engine Yandex. We compare our metric with recently proposed SpU (sessions per user) metric and other widely used query-level A/B metrics, such as Abandonment Rate and Time to First Click, which we used as our baseline metrics. We observed that pSwitch metric is more sensitive in comparison with those baseline metrics and also that pSwitch and SpU are more consistent with ground truth, than Abandonment Rate and Time to First Click.
Non-metallurgical bonding technology with super-narrow gap for 3D stacked LSI (2003)

The chip-stacking technologies with the thin devices in hyperfine pitch realize both of the strong demands for the high-speed signal transmission and the high-density packaging. The results of the experiments on the non-metallurgical bonding and encapsulation with nonconductive particle paste (NCP) are introduced. It realizes void-free encapsulation of under 10-/spl mu/m-thick gap, small warpage of 50-/spl mu/m-thick chip, and ohmic contact of all of 1844 bumps in 20-/spl mu/m-pitch. Additionally, it is found the flatness of chip backside is achieved sufficient level for the thin chip stacking process with hyper fine pitch interconnection.
On the Origin of the Negative Thermal Expansion Behavior of YCu (2019)

Among the intermetallics and alloys, YCu is an unusual material because it displays negative thermal expansion without spin ordering. The mechanism behind this behavior that is caused by the structural phase transition of YCu has yet to be fully understood. To gain insight into this mechanism, we experimentally examined the crystal structure of the low-temperature phase of YCu and discuss the origin of the phase transition with the aid of thermodynamics calculations. The result shows that the high-temperature (cubic CsCl-type) to low-temperature (orthorhombic FeB-type) structural phase transition is driven by the rearrangement of three covalent bonds, namely, Y-Cu, Y-Y, and Cu-Cu, which compete for the bonding energy and phonon entropy. At low temperatures, the mixing of Y and Cu does not take place easily because of the weak attractive force between these atoms expected from the small negative mixing enthalpy. This causes all three interactions to take part in the bonding, and Y and Cu are segregated to form an FeB-type structure, which is stabilized by internal energy. At higher temperatures, Cu ions are bound loosely with Y ions due to the large Y-Cu distance (3.01 Å), which results in large vibration entropy and stabilizes a CsCl-type crystal structure. In addition, the CsCl-type structure is reinforced by the Y-Y interaction between next-nearest neighbors, resulting in a smaller unit cell volume. The crystal structure has the simple cubic framework of Y containing Cu ions bound loosely at the cavity sites. The calculated frequency of the Y-like phonon modes is much higher than that of the Cu-like modes, indicating the presence of Y-Y covalent interactions in the CsCl-type phase.

Adaptive background interference removal for Fourier ptychographic microscopy (2018)

Fourier ptychographic microscopy (FPM) is a recently proposed computational imaging method that achieves both high resolution (HR) and wide field of view. In the conventional FPM model, the sample is assumed to be a 2D thin layer, and a series of low-resolution images at different illumination angles is used for HR image reconstruction. However, in practice, the sample complex amplitude distribution is usually mixed with some unknown background interferences. These background interferences may result from inhomogeneous media distribution or other defocusing layers, etc. The background interference will significantly degrade FPM reconstruction results, but so far it is not considered in the conventional FPM algorithm. Here, we propose a method that adaptively separates background interferences for each illumination angle. Experimental results show that the proposed method has a faster convergence speed and better reconstruction accuracy than the conventional FPM model.
Inhibitory Effect of KP-A038 on Osteoclastogenesis and Inflammatory Bone Loss Is Associated With Downregulation of Blimp1 (2019)

Excessive osteoclastic activity results in pathological bone resorptive diseases, such as osteoporosis, periodontitis, and rheumatoid arthritis. As imidazole-containing compounds possess extensive therapeutic potential for the management of diverse diseases, we synthesized a series of imidazole derivatives and investigated their effects on osteoclast differentiation and function. In the present study, we found that a novel imidazole derivative, KP-A038, suppressed receptor activator of nuclear factor-κB ligand (RANKL)-mediated osteoclastogenesis and bone-resorbing activity <i>in vitro</i> and attenuated lipopolysaccharide (LPS)-induced bone destruction <i>in vivo</i>. KP-A038 significantly inhibited the induction of nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1) and the expression of its target genes, including tartrate-resistant acid phosphatase (<i>Acp5</i>), cathepsin K (<i>Ctsk</i>), dendritic cell-specific transmembrane protein (<i>Dcstamp</i>), and matrix metallopeptidase 9 (<i>Mmp9</i>). KP-A038 upregulated the expression of negative regulators of osteoclast differentiation, such as interferon regulatory factor-8 (<i>Irf8</i>) and B-cell lymphoma 6 (<i>Bcl6</i>). Consistently, KP-A038 downregulated the expression of B lymphocyte-induced maturation protein-1 (Blimp1 encoded by <i>Prdm1</i>), a repressor for <i>Irf8</i> and <i>Bcl6</i>. Moreover, administration of KP-A038 reduced LPS-induced bone erosion by suppressing osteoclast formation <i>in vivo</i>. Thus, our findings suggest that KP-A038 may serve as an effective therapeutic agent for the treatment and/or prevention of bone loss in pathological bone diseases, including osteoporosis and periodontitis.

Enhancement of Speech Recognitions for Control Automation Using an Intelligent Particle Swarm Optimization (2012)

For over two decades, speech control mechanisms have been widely applied in manufacturing systems such as factory automation, warehouse automation, and industrial robotic control for over two decades. To implement speech controls, a commercial speech recognizer is used as the interface between users and the automation system. However, users' commands are often contaminated by environmental noise which degrades the performance of speech recognition for controlling automation systems. This paper presents a multichannel signal enhancement methodology to improve the performance of commercial speech recognizers. The proposed methodology aims to optimize speech recognition accuracy of a commercial speech recognizer in a noisy environment based on a beamformer, which is developed by an intelligent particle swarm optimization. It overcomes the limitation of the existing signal enhancement approaches whereby the parameters inside commercial speech recognizers are required to be tuned, which is impossible in a real-world situation. Also, it overcomes the limitation of the existing optimization algorithm including gradient descent methods, genetic algorithms and classical particle swarm optimization that are unlikely to develop optimal beamformers for maximizing speech recognition accuracy. The performance of the proposed methodology was evaluated by developing beamformers for a commercial speech recognizer, which was implemented on warehouse automation. Results indicate a significant improvement regarding speech recognition accuracy.
ABA triblock copolymers: from controlled synthesis to controlled function (2003)

The ABA amphiphilic block copolymers, poly(hydroxyethyl methacrylate-block-methylphenylsilane-block-hydroxyethyl methacrylate) (PHEMA–PMPS–PHEMA) and poly[oligo(ethylene glycol) methyl ether methacrylate-block-methylphenylsilane-block-oligo(ethylene glycol) methyl ether methacrylate] (POEGMA–PMPS–POEGMA) were successfully synthesised via atom transfer radical polymerisation (ATRP). Macroinitiators suitable for the ATRP of oligo(ethylene glycol) methyl ether methacrylate and 2-hydroxyethyl methacrylate were synthesised from the condensation reaction of α,ω-dihalopolymethylphenylsilane and 2′-hydroxyethyl 2-bromo-2-methylpropanoate. The copolymers were characterised using 1H NMR and 13C NMR spectroscopy and molecular weight characteristics were determined using size exclusion chromatography and 1H NMR. The aggregation behaviour of some of the copolymers in water was studied using transmission and scanning electron microscopy and dynamic light scattering. These revealed the prevalent aggregate species to be micelles. Larger aggregates of 300–1000 nm diameter were also observed. The UV induced degradation of the aggregates was studied by UV-Vis spectroscopy. The thermal behaviour of selected copolymers was studied by differential scanning calorimetry and microphase separation of the two components was demonstrated.
Inter-view coding for stereoscopic Digital Cinema (2008)

An inter-view coding scheme is proposed for stereoscopic video applications such as 3D Digital Cinema. It tackles inter-view redundancy with efficient inter-view disparity-compensated filtering. In the temporal dimension, intra-coding with JPEG2000 is used to meet Digital Cinema specific requirements in terms of latency and random access. Inter-view disparity, as well as uncovered areas, are efficiently addressed within the inter-view Haar transform, and the resulting overhead information only amounts to a few percents of the bitstream. The proposed stereoscopic coding scheme delivers both left and right views with a high level of quality and yields to significant improvement in terms of bitrate saving and image quality in comparison with simulcast.
VL-ROUTE: A Cross-Layer Routing Protocol for Visible Light Ad Hoc Network (2019)

Visible Light Ad Hoc Networks (LANETs)is being perceived as an emerging technology to complement Radio Frequency (RF)based ad hoc networks to reduce congestion in the overloaded RF spectrum. LANET is intended to support scenarios requiring dense deployment and high data rates. In Visible Light Communication (VLC), most of the attention has been centered around physical layer with emphasis on point-to-point communication. In this work, we focus on designing a routing protocol specifically to overcome the unique challenges like blockage and deafness that render routes in LANETs highly unstable. Therefore, we propose a cross-layer optimized routing protocol (VL-ROUTE)that interacts closely with the Medium Access Control (MAC)layer to maximize the throughput of the network by taking into account the reliability of routes. To accomplish this in a distributed manner, we carefully formulate a Route Reliability Score (RRS)that can be computed by each node in the network using just the information gathered from its immediate neighbors. Each node computes an RRS for every known sink in the network. RRS of a given node can be considered as an estimate of the probability of reaching a given sink via that node. The RSS value is then integrated to the utility based three-way handshake process used by the MAC protocol (VL-MAC)to mitigate the effects of deafness, blockage, hidden node, and maximize the probability of establishing full-duplex links. All these factors contribute towards maximizing the network throughput. Extensive simulation of VL-ROUTE shows 124% improvement in network throughput over a network that uses Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA)along with shortest path routing. Additionally, VL-ROUTE also showed up to 21% improvement in throughput over the network that uses VL-MAC along with a geographic routing.

Comprehensive Phylogenetic Reconstructions of Rift Valley Fever Virus: The 2010 Northern Mauritania Outbreak in the Camelus dromedarius Species (2014)

Rift valley fever (RVF) is a mosquito-borne disease of domestic and wild ruminants caused by RVF virus (RVFV), a phlebovirus (Bunyaviridae). RVF is widespread in Sub-Saharan Africa. In September of 2010, an RVF outbreak occurred in northern Mauritania involving mass abortions in small ruminants and camels (Camelus dromedarius) and at least 63 human clinical cases, including 13 deaths. In camels, serological prevalence was 27.5-38.5% (95% confidence interval, n=279). For the first time, clinical signs other than abortions were reported in this species, including hemorrhagic septicemia and severe respiratory distress in animals. We assessed the presence of RVFV in camel sera sampled during this outbreak and generated whole-genome sequences of RVFV to determine the possible origin of this RVFV strain. Phylogenetic analyses suggested a shared ancestor between the Mauritania 2010 strain and strains from Zimbabwe (2269, 763, and 2373), Kenya (155_57 and 56IB8), South Africa (Kakamas, SA75 and SA51VanWyck), Uganda (Entebbe), and other strains linked to the 1987 outbreak of RVF in Mauritania (OS1, OS3, OS8, and OS9).

Nucleoside Diphosphate Prodrugs (2008)

Nucleoside analogs are widely applied in antiviral and antitumor therapy. A severe limitation of these compounds arises from the need of biotransformation to the eventually active nucleoside triphosphates by stepwise addition of phosphate by kinases. This problem can be circumvented by employing reversibly masked nucleotides (prodrugs). However, the known concepts to bypass enzyme activation have almost exclusively been applied to nucleoside monophosphates. Here, we report on the transfer of the bis-(acyloxybenzyl)-concept (BAB-concept) from nucleoside monophosphates to nucleoside diphosphates (NDP) of the anti HIV drugs AZT and d4T. After successful synthesis and isolation of the compounds (BAB-NDPs), it was shown that these compounds exhibit promising hydrolytic properties ranging from high stability at physiological pH to very low stability in cellular extracts. Furthermore, we demonstrated that for some of the compounds a selective cleavage mechanism resulted in the exclusive delivery of the corresponding nucleoside diphosphate within 15 minutes without any degradation of the pyrophosphate unit, which is a unique result in the field of NDP-prodrugs.
A memristor-based third-order oscillator: beyond oscillation (2011)

This paper demonstrates the first third-order autonomous linear time variant circuit realization that enhances parametric oscillation through the usage of memristor in conventional oscillators. Although the output has sustained oscillation, the linear features of the conventional oscillators become time dependent. The poles oscillate in nonlinear behavior due to the oscillation of memristor resistance. The mathematical formulas as well as SPICE simulations are introduced for the memristor-based phase shift oscillator showing a great matching.

Fault Tolerant Platform for Communication and Distance Measurement in Highly Automated Driving (2020)

The dream towards fully autonomous vehicles brings a lot of challenges in terms of reliability, high performance computing and sensing capabilities in a vehicle. Nowadays, autonomous vehicles are equipped with several sensors, which allow the vehicle to sense everything on the road and to collect the information needed to drive safely. Altogether, these sensors generate a lot of data, roughly 4TB in a single day [1]. In order to process this abundance of sensory data faster and reliably, there is a need for high performance microcontroller units (MCUs) and fault tolerant data processing respectively. For this reason, we have developed a smart reconfigurable sensor (SRS) platform, which aims to solve the challenges of high performance computing and safety. An in-house fabricated entire silicon-based millimeter-wave transceiver, using IHP's 130 nm SiGe BiCMOS technology, is used as SRS front-end and software (SW) based triple modular redundancy (TMR) system is implemented for fault tolerant radar data processing. Our highly adaptive system supports fault tolerant modes (i.e. fail operational, fail safe), low power mode and distributed execution of tasks among different cores, all while meeting the strict automotive standards.
Multiplex systems for automobiles (1980)

Multiplexing is recommended as the best functional and most cost-effective approach for future automotive electrical wiring systems. The proven advantages of a multiplex control system are listed: reduced number of circuits, small gauge control wires, smaller installation space requirement, lower installation weight, expandability for added functions, and standardized harness configuration. Technology employed in multiplex data systems for automotive applications is discussed: Time Division Multiplex (TDM) systems, spoke and ring types of data links, and data word format and typical communication cycle for spoke type TDM systems. Electromagnetic compatibility considerations are addressed. Circuits are diagrammed for an OPTIPLEX test vehicle developed by General Motors, a 1979 Oldsmobile station wagon equipped with fiber optic steering column and door/seat multiplex harness systems.
Sheathless Electrospray from Polymer Microchips (2003)

In this study, sheathless electrospray from polymer microchips with conducting layer on the emitter tip is described for the first time. The electrospray emitter tips were fabricated directly from the end of the microchips that were made of polycarbonate or poly(methyl methacrylate) with injection molding. A variety of tip shapes and conducting coatings were evaluated using an electrospray time-of-flight mass spectrometer run in the sheathless mode. Stable electrospray was obtained both from hand-polished and machine-milled three-dimensional tips coated with either polymer-embedded gold particles or graphite particles as the conducting layer. Sputtered gold, on the other hand, suffered from poor stability mainly due to bad adhesion to the polymer tip. The durability of the different coatings was confirmed with electrochemical experiments under simulated electrospray conditions. The relative standard deviations of the response received from the ion current of the MS analysis were in the range of 3.5-12%. The detection limit for a standard mixture containing five neuropeptides was lower than 0.5 fmol. The low detection limit makes the emitter tips highly attractive for the analysis of low-abundance biological species.
