A novel compact dual‐band bandpass filter using spiral‐shaped microstrip resonators (2010)

Abstract In this letter, a dual‐band bandpass filter is proposed by consisting of spiral‐shaped microstrip resonators. Meanwhile, a skew‐symmetric tapped feed structure is applied to introduce two transmission zeros on both sides of individual passbands, and thereby improve the filter selectivity. The measured results of the designed third‐order dual‐band bandpass filter for 2.4/5.2 GHz wireless local area network applications are in good agreement with the simulated predictions. Moreover, the filter has a size reduction of 40%, as compared with the conventional square open‐loop bandpass filters. © 2010 Wiley Periodicals, Inc.

Highly reliable, complementary atom switch (CAS) with low programming voltage embedded in Cu BEOL for Nonvolatile Programmable Logic (2011)

A novel complementary atom switch (CAS) embedded in Cu BEOL has been developed to realize low programming voltage of 2V and extremely high disturbance reliability of OFF-state (T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.1</sub> >;10 years at 1V, 125°C). The decrement of solid-electrolyte density successfully reduces the programming voltage down to 2V. Two bipolar resistive-change elements such as atom switches are connected in series with opposite direction, in which the two OFF-state elements complementarily divide the voltage stress, greatly enlarging the OFF-state lifetime. The highly reliable, complementary atom switch is a promising device for energy efficient, Nonvolatile Programmable Logic (NPL).
Low power storage cycle budget distribution tool support for hierarchical graphs (2000)

In data-dominated applications, like multimedia and telecommunications applications, storage and transfers are the most important factors in terms of energy consumption, area and system performance. Several steps which optimize these costs are present in our systematic data transfer and storage exploration methodology. In the important step discussed in this paper, the cycle budget available for background storage transfers is globally distributed over the application's memory accesses that are typically grouped in the loop and function hierarchy. This is crucial for meeting the real-time constraints with a customized memory organisation without counteracting the memory size and energy budget optimizations achieved by earlier steps in our script. This paper proves the effectiveness of the prototype tool on driver applications of several application domains. It clearly shows the tradeoff between power, area and speed.
Microstrip equivalent parasitics modeling of RFIC interconnects (2007)

We experimentally demonstrate a modeling methodology for inductive parasitics of RFIC interconnects. The method exploits the equivalence between a microstrip line and the cross section of a multi metal layer CMOS fabrication process. The proposed model is applied on an oscillator fabricated in a standard 0.18μm mixed mode CMOS process. We compare the experimental results of the phase noise of the oscillator so fabricated with the simulation results using the microstrip equivalent model for the interconnects. The simulation and experimental results match very closely.
Coupled VO2 oscillators circuit as analog first layer filter in\n convolutional neural networks (2020)

In this work we present an in-memory computing platform based on coupled VO2\noscillators fabricated in a crossbar configuration on silicon. Compared to\nexisting platforms, the crossbar configuration promises significant\nimprovements in terms of area density and oscillation frequency. Further, the\ncrossbar devices exhibit low variability and extended reliability, hence,\nenabling experiments on 4-coupled oscillator. We demonstrate the neuromorphic\ncomputing capabilities using the phase relation of the oscillators. As a\napplication, we propose to replace digital filtering operation in a\nconvolutional neural network with oscillating circuits. The concept is tested\nwith a VGG13 architecture on the MNIST dataset, achieving performances of 95%\nin the recognition task.\n
Query languages and a unifying framework for non-traditional data models (1993)

Data models differ in the types of modeling constructs that they provide and hence in the types of applications that they support. The inability of traditional data models to support the increasingly complex database applications has inspired the creation of several advanced data models. This dissertation describes research on non-traditional data models from the perspective of designing query languages for the models and finding a common framework for describing them.
Query languages are designed for two different data models--the nested relational model and the list-structure model. The nested relational model is a recursive extension of the relational model which allows values in a relation to be relations. The query language that is designed is a recursive extension of the relational algebra. Since the query language mirrors the recursive nature of the model it overcomes some of the problems of languages that are simplistic extensions of the relational algebra and is hence better suited for the kinds of applications that the model is meant to support.
Most models, like the relational and nested relational models, support set-oriented applications. The list-structure model is targeted towards applications that require support for complex objects based on lists. A query language based on list-oriented operations is designed for this model. The language reflects both the recursively hierarchical and the list-based structure of the model.
The use of logic as a unifying framework for describing data models is investigated. From a practical point of view, this is an initial step towards designing systems that can provide the capabilities of several different models. From a theoretical perspective, it gives us a common framework for defining database concepts and for describing and comparing data models. Some ideas on how the framework may be used to study semantic equivalences of data models are also presented.
Supramolecular-Directed Chiral Induction in Biaryl Derivatives (2009)

A thermodynamically controlled resolution has allowed for the generation of diastereomerically enriched complexes, by chirality transfer from an enantiopure building block to a dynamically racemic biaryl derivative. A switchable sense of induction could be achieved depending on the substituents of the chiral block.
Population Structure and Antimicrobial Resistance Profiles of Streptococcus suis Serotype 2 Sequence Type 25 Strains (2016)

Strains of serotype 2 Streptococcus suis are responsible for swine and human infections. Different serotype 2 genetic backgrounds have been defined using multilocus sequence typing (MLST). However, little is known about the genetic diversity within each MLST sequence type (ST). Here, we used whole-genome sequencing to test the hypothesis that S. suis serotype 2 strains of the ST25 lineage are genetically heterogeneous. We evaluated 51 serotype 2 ST25 S. suis strains isolated from diseased pigs and humans in Canada, the United States of America, and Thailand. Whole-genome sequencing revealed numerous large-scale rearrangements in the ST25 genome, compared to the genomes of ST1 and ST28 S. suis strains, which result, among other changes, in disruption of a pilus island locus. We report that recombination and lateral gene transfer contribute to ST25 genetic diversity. Phylogenetic analysis identified two main and distinct Thai and North American clades grouping most strains investigated. These clades also possessed distinct patterns of antimicrobial resistance genes, which correlated with acquisition of different integrative and conjugative elements (ICEs). Some of these ICEs were found to be integrated at a recombination hot spot, previously identified as the site of integration of the 89K pathogenicity island in serotype 2 ST7 S. suis strains. Our results highlight the limitations of MLST for phylogenetic analysis of S. suis, and the importance of lateral gene transfer and recombination as drivers of diversity in this swine pathogen and zoonotic agent.

Fabrication of Nanostructured Platinum with Multilevel Porosity for Low Impedance Biomedical Recording and Stimulation Electrodes (2015)

We report a new lithography-free technology to fabricate porous metal electrodes with multiple levels of porosity, from macroporous – about 1 μm pore diameter – down to nanoporous – 3 nm diameter. The hierarchical combination of mesopores and nanopores allows deeper layers of the electrode to be better accessible for the liquid the electrode is immersed in, aiming to further reduce the impedance of microscale electrodes for biomedical applications. Up to 1000x reduction in impedance was measured in the first experiments, combined with a 230x increase in charge injection capacity. Next to presenting the new and widely applicable (beyond Pt) fabrication process, this is also the first time hierarchical porosity is used in biomedical electrode fabrication.
MP-trie (2016)

As spatial data being collected by various industries (e.g., telecommunication, insurance, automotive) is on the increase, indexing and answering queries extremely quickly is necessary. This paper proposes a new mechanism, Mobile PATRICIA-trie (MP-trie), for fast queries on moving objects that provides a 1000x improvement in performance over state-of-the-art spatial indexing mechanisms. We reduce the problem of spatial indexing to that of prefix-matching over binary strings, which is then coupled with off-the-shelf commercially available content-addressable memory (commonly used in IP routers for forwarding table lookups). We validate our approach on data collected from a real-world deployment in Stockholm, Sweden across 2000 cars for a period of one month.
A new approach in teaching power electronics control of electrical drives using real-time systems (2002)

A new approach in teaching power electronics and electrical drives is achieved at the Flexible Drives System Laboratory (FDSL) from Aalborg University by using the new Total Development Environment (TDE) concept that allows a full visual block-oriented programming of dynamic real-time systems to be done using the Matlab/Simulink environment. Basics in electrical drives and advanced control of PWM inverter fed induction machines courses are successfully using the new facility and an increased student enrollment is expected in the coming years.
Ultra fast relay with small communication requirements (2013)

Protection relays play a very important role in network security. Both the network stability and energy availability depend to a great extent on algorithms and protection concepts. This paper presents a novel, very fast protection algorithm that is based on directional comparison. The algorithm is robust against many states and phenomena appearing in the network, e.g. load flow fluctuation, power swings or frequency deviations. The method is also robust against some phenomena connected with secondary system design like CTs saturation, synchronisation deviation or the transient effects in CVTs. The small communication requirements mean that this concept can be applied in existing power networks protected by differential relays with limited band width. The main idea of the algorithm as well as an example is presented in this paper. (4 pages)
A Compact CNN-DBLSTM Based Character Model for Online Handwritten Chinese Text Recognition (2017)

Recently, character model based on integrated convolutional neural network (CNN) and deep bidirectional long short-term memory (DBLSTM) has been demonstrated to be effective for online handwritten Chinese text recognition (HCTR). However, the reported CNN-DBLSTM topologies are too complex to be practically useful. In this paper, we propose a compact CNN-DBLSTM which has small footprint and low computation cost yet be able to accommodate multiple receptive fields for CNN-based feature extraction. By using the training set of a popular benchmark database, namely CASIA-OLHWDB, we trained a compact CNN-DBLSTM by a connectionist temporal classification (CTC) criterion with a multi-step training strategy. Combined this character model with a character trigram language model, our online HCTR system with a WFSTbased decoder has achieved state-of-the-art performance on both CASIA and ICDAR-2013 Chinese handwriting recognition competition test sets.

Partial denaturation of mouse DNA in preparative cesium chloride density gradients at alkaline pH (1976)

A new technique--partial denaturation of DNA in equilibrium CsCl density gradients at pH 11.4--is used to determine the distribution of intermediate states in the melting of mouse DNA. When the technique is applied in the preparative ultracentrifuge, the DNA is fractionated according to stability. Neutralization of the partially denatured fractions results in the recovery of most of the DNA in its native form. The individual fractions are more homogeneous than the total DNA: they have decreased density heterogeneity (smaller band widths), neutral CsCl buoyant densities that differ from the average, and more homogeneous melting profiles with melting temperatures that differ from the average.
Predictive power of indices derived from models of biological dynamic systems (2008)

We are given a reliable parametric model of a system whose structure and parameter values can be obtained by an identification experiment. Often, one or more indices can be determined as a function of model parameters, i.e. an index is a function that maps the parameter space into the real line. The aim of these indices is to incorporate as much information as possible on a certain phenomenon of interest described by the model. The paper proposes an approach to compare competitive indices in terms of predictive power of system output. The new concept is applied to the minimal model of glucose kinetics, by comparing the performance of two different insulin sensitivity indices whose objective is to describe insulin ability to control glucose.

GUIDED WAVE TRAVEL TIME TOMOGRAPHY FOR BENDS (2011)

The concept of predictive maintenance using permanent sensors that monitor the integrity of an installation is an interesting addition to the current method of periodic inspections. Guided wave tomography has been developed to map the wall thickness using the travel times of guided waves. The method has been demonstrated for straight pipes. The extension of this method to bends is not straightforward because natural focusing occurs due to geometrical path differences. This yields a phase jump, which complicates travel time picking. Because ray‐tracing is no longer sufficient to predict the travel times a recursive wave field extrapolation has been developed. The method uses a short spatial convolution operator to propagate a wave field through a bend. The method allows to calculate the wave field at the detector ring, including the phase jump as a consequence of the natural focusing. The recursive wave field extrapolation is done in the space‐frequency domain. Therefore dispersion effects can be included easily in the forward modeling. Comparison with measurements shows the accuracy of the method.

This represents the first general method for the ortho-dimethylation of tyrosine derivatives and offers a practical approach for preparing this synthetically important building block. Notably, throughout the reaction sequence no racemization occurs at the susceptible α-chiral centers.

Polymer Solar Cells with Long-Term Thermal Stability and High-Efficiency Based on Photocrosslinkable Donor-Acceptor Conjugated Polymers (2011)

This work reports on the long-term thermal stability of highly efficient organic photovoltaic devices (OPVs) based on donor-acceptor copolymers. Photocrosslinkable derivatives of a thieno[3,4-c]pyrrole-4,6-dione (TPD)-based polymer were developed and used as electron donating material in BHJ solar cells. By synthetically tuning the amount of photocrosslinkable moiety in the polymer and by employing UV-mediated photocrosslinking, it was possible to fabricate OPV devices with high power conversion efficiency (PCE) and excellent thermal stability. In particular, after 72 h of thermal annealing at 150 °C, an average PCE of 4.6% was obtained with a short circuit current density (J SC) of 10.1 mA/cm2, an open circuit voltage (V OC) of 0.85 V, and a fill factor (FF) of 54%. The peak PCE obtained was as high as 4.7%. In addition, the choice of fullerene acceptor in the BHJ was found to be critical not only for achieving high PCE but also for stabilizing the morphology of the active layer at high temperature. Atomic force microscopy (AFM) was employed to investigate the surface morphology of the active layer in both crosslinked and non-crosslinked films before and after annealing.
Coupled RT-fluxgates (2006)

A novel system, based on oscillating coupled hysteretic fluxgates, that allows the measuring of weak magnetic fields is presented here. The core device is the "residence times differences fluxgate" magnetometer (RT-fluxgate). The coupling of such systems via a linear unidirectional connection can lead to synchronized oscillations past a critical value of the coupling coefficient. The oscillation signal is very sensitive to small changes in target magnetic field and thus this coupled device can be used to quantify a weak target signal. A device prototype has been developed, and experimental characterizations showed oscillation phenomena and frequency shift in the presence of dc target signal as expected.
