Mode-Based Beamforming Arrays for Miniaturized Platforms (2008)

In this paper, a new and practical mode-based array concept is proposed. The key principle of this mode-based approach is the use of orthogonal radiation modes existing in highly coupled arrays as individual information channels so as to avoid mutual coupling and correlation. Consequently, mode-based arrays can be very compact in size but without suffering undesired effects such as impedance mismatch or pattern distortion. While providing a general theoretical discussion for this mode-based approach, a practical application example, namely, a compact electronically scanning array module is developed. With a suitable signal combining algorithm, the module is capable of forming and full 360 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">deg</sup> scanning of a high-gain radiation pattern in the azimuth plane. An experimental prototype has been fabricated on a traditional printed circuit board to validate the practicability of the proposed concept. Measurement results obtained are in good agreement with theoretical simulations, showing promising potential of mode-based array modules for modern miniaturized wireless devices.
Acoustruments (2015)

We introduce Acoustruments: low-cost, passive, and power-less mechanisms, made from plastic, that can bring rich, tangible functionality to handheld devices. Through a structured exploration, we identified an expansive vocabulary of design primitives, providing building blocks for the construction of tangible interfaces utilizing smartphones' existing audio functionality. By combining design primitives, familiar physical mechanisms can all be constructed from passive elements. On top of these, we can create end-user applications with rich, tangible interactive functionalities. Our experiments show that Acoustruments can achieve 99% accuracy with minimal training, is robust to noise, and can be rapidly prototyped. Acoustruments adds a new method to the toolbox HCI practitioners and researchers can draw upon, while introducing a cheap and passive method for adding interactive controls to consumer products.
Concentration-Gradient Stabilization with Segregated Counter- and Co-Ion Paths: A Quasistationary Depletion Front for Robust Molecular Isolation or Concentration (2017)

We study the spatiotemporal dynamics of a microfluidic system with a nonselective microfluidic channel gated by an ion-selective membrane which separates the ion flux paths of cations and anions. To preserve electroneutrality, the ionic concentration in the system is shown to converge to a specific inhomogeneous distribution with robust constant current fluxes. A circuit scaling theory that collapses measured asymptotic currents verifies that this is a generic and robust mechanism insensitive to channel geometry, ion selectivity, and electrolyte ionic strength. This first temporally stationary but spatially inhomogeneous depletion front can be used for modulating ionic current and for isotachophoretic isolation of low-mobility molecules and exosomes on small diagnostic chips for various medical applications that require robust high-throughput and integrated platforms.

Synthesis and characterization of block copolymers from 2‐vinylnaphthalene by anionic polymerization (2002)

Abstract The anionic polymerization of 2‐vinylnaphthalene (2VN) has been studied in tetrahydrofuran (THF) at −78 °C and in toluene at 40 °C. 2VN polymerization in THF, toluene, or toluene/THF (99:1 v/v) initiated by sec ‐butyllithium (sBuLi) indicates living characteristics, affording polymers with predefined molecular weights and narrow molecular weight distributions. Block copolymers of 2VN with methyl methacrylate (MMA) and tert ‐butyl acrylate (tBA) have been synthesized successfully by sequential monomer addition in THF at −78 °C initiated by an adduct of sBuLi–LiCl. The crossover propagation from poly(2‐vinylnaphthyllithium) (P2VN) macroanions to MMA and tBA appears to be living, the molecular weight and composition can be predicted, and the molecular weight distribution of the resulting block copolymer is narrow (weight‐average molecular/number‐average molecular weight < 1.3). Block copolymers with different chain lengths for the P2VN segment can easily be prepared by variations in the monomer ratios. The block copolymerization of 2VN with hexamethylcyclotrisiloxane also results in a block copolymer of P2VN and poly(dimethylsiloxane) (PDMS) contaminated with a significant amount of homo‐PDMS. Poly(2VN‐ b ‐nBA) (where nBA is n ‐butyl acrylate) has also been prepared by the transesterification reaction of the poly(2VN‐ b ‐tBA) block copolymer. Size exclusion chromatography, Fourier transform infrared, and 1 H NMR measurements indicate that the resulting polymers have the required architecture. The corresponding amphiphilic block copolymer of poly(2VN‐ b ‐AA) (where AA is acrylic acid) has been synthesized by acidic hydrolysis of the ester group of tert ‐butyl from the poly(2VN‐ b ‐tBA) copolymer. © 2002 Wiley Periodicals, Inc.

Data Prefetching and Data Forwarding in Shared Memory Multiprocessors (1994)

This paper studies and compares the use of data prefetching and an alternative mechanism, data forwarding, for reducing memory latency due to interprocessor communication in cache coherent, shared memory multiprocessors. Two multiprocessor prefetching algorithms are presented and compared. A simple blocked vector prefetching algorithm, considerably less complex than existing software pipelined prefetching algorithms, is shown to be effective in reducing memory latency and increasing performance. A Forwarding Write operation is used to evaluate the effectiveness of forwarding. The use of data forwarding results in significant performance improvements over data prefetching for codes exhibiting less spatial locality. Algorithms for data prefetching and data forwarding are implemented in a parallelizing compiler. Evaluation of the proposed schemes and algorithms is accomplished via execution-driven simulation of large, optimized, parallel numerical application codes with loop-level and vector parallelism. More data, discussion, and experiment details can be found in [1].
Additive Effect of Triphenylphosphine on the Living Polymerization of 1,3‐Butadiene with a Cobalt Dichloride‐Methylaluminoxane Catalytic System (2003)

Abstract The additive effect of triphenylphosphine (Ph 3 P) was investigated in 1,3‐butadiene polymerization with cobalt dichloride (CoCl 2 ) activated by methylaluminoxane (MAO); the catalytic system resulted in slowly‐initiated living polymerization with a high cis ‐1,4 content (about 99%) at 0 °C. The polymerization behavior, such as the relationship of polymer yield and number‐average molecular weight ( $\overline M _{\rm n}$ ) with polymerization time, was dependent on the amount of Ph 3 P added. In the presence of a small amount of Ph 3 P (Ph 3 P/Co = 0.025), the kinetic behavior qualitatively resembled that observed in the absence of Ph 3 P, which indicated that the catalytic system conducted slowly‐initiated living polymerization. An increase in the amount of Ph 3 P (Ph 3 P/Co > 0.025), however, caused chain transfer reaction. The 1 H NMR analysis of the produced polymers showed that Ph 3 P changed the microtacticity from 99% of cis ‐1,4 to 88% of 1,2‐unit, depending on the amount of Ph 3 P added. At the maximum amount of Ph 3 P (Ph 3 P/Co = 0.025) necessary for maintaining the livingness of the propagating species, 14% of the 1,2‐inserted unit was incorporated at the expense of the cis ‐1,4‐inserted unit. The addition of Ph 3 P (Ph 3 P/Co = 0.025) during the polymerization did not affect the livingness and gave a regio‐block copolymer of 1,3‐butadiene.

Traffic sign shape classification evaluation I: SVM using distance to borders (2005)

This paper deals with the detection and classification of traffic signs in outdoor environments. The information provided by traffic signs on roads is very important for the safety of drivers. However, in these situations the illumination conditions can not be predicted, the position and the orientation of signs in the scene are not known and other objects can block the vision of them. For these reasons we have developed an extensive test set which includes all kind of signs. In an artificial vision system, the key to recognize traffic signs is how to detect them and identify their geometric shapes. So, in this work we propose a method that uses a technique based on support vector machines (SVMs) for the classification. The patterns generated by the vectors represent the distances to borders (DtB) of the objects candidate to be traffic signs. Experimental results show the effectiveness of the proposed method.
Locoregional Therapies for Hepatocellular Carcinoma: A Critical Review From the Surgeon’s Perspective (2002)

Advances in locoregional therapies have led to a major breakthrough in the management of unresectable HCC, but the exact role of the various modalities needs to be defined by randomized studies. Novel thermoablative techniques provide the surgeon with an exciting opportunity to participate actively in the management of unresectable HCC. Locoregional therapies are also useful adjuncts in the management of patients with resectable or transplantable disease. Hence, surgeons must be equipped with the latest knowledge and techniques of ablative therapy to provide the most appropriate treatment for the wide spectrum of patients with HCC.
Characteristic Mode based antenna design — A straight forward approach to small form factor antenna integration (2015)

The Theory of Characteristic Modes proved to be a useful tool for the analysis and design of antennas integrated into various modern application. The metallic chassis of a smart phone can be excited by small coupling elements to effectively work as a multiband antenna or a multi antenna system with high isolation between its ports. Compact massive antenna arrays can be generated by exciting multiple modes on each array element. The array can then be either configured as a massive multi antenna system for MIMO or a multi mode beamforming array. For automotive applications the chassis of the car can be utilized as a whole as a terrestrial radio reception antenna or smaller chassis parts such as the rear view mirror can be excited to effectively work as antennas for mobile communications or car2× applications.

Epidemiology of Inhibitors inHaemophilia A (1996)

One of the most serious complications of the treatment of haemophilia A is the development of inhibitors. Former studies mostly considered the prevalence of inhibitor development, thus underestimating its true risk. Prevalences ranged widely (7-18%) probably due to the populations studied and the study design. Recent prospective previously untreated patients (PUP) studies were more comparable because of similar study designs. Eight PUP studies regarding the incidence of factor VIII inhibitors were analyzed: The inhibitor incidences (Independent of severity of haemophilia) ranged from 18.4 to 28%. Evaluating only severe haemophiliacs (factor VIII <2%) significantly higher incidences were found. After 9-36 exposure days (as medians inhibitor development occurred at 0.8-3.3 years of age (as medians).
Accurate noise variance estimation scheme for ordered successive detection in MIMO systems (2004)

Ordered successive MMSE detection (OSD) can achieve a good tradeoff between performance and complexity for multiple-input multiple-output (MIMO) wireless systems where different data streams are transmitted and received simultaneously over several equal number of transmit and receive antennas. However, over time-varying MIMO channels, the performance of OSD is degraded with realistic channel estimation. The accuracy of the generated nulling weights is improved by using a modified noise variance that takes into consideration the weights update lag error besides to the noise and channel estimation errors is proposed in this paper. Simulation results by using the proposed modified noise variance estimation scheme show significant performance improvements for OSD.
Increased ROS production in non-polarized mammary epithelial cells induces monocyte infiltration in 3D culture (2016)

Loss of epithelial cell polarity promotes cell invasion and cancer dissemination. Therefore, identification of factors that disrupt polarized acinar formation is crucial. Reactive oxygen species (ROS) drive cancer progression and promote inflammation. Here, we show that the non-polarized breast cancer cell line T4-2 generates significantly higher ROS levels than polarized S1 and T4R cells in three-dimensional (3D) culture, accompanied by induction of the nuclear factor κB (NF-κB) pathway and cytokine expression. Minimizing ROS in T4-2 cells with antioxidants reestablished basal polarity and inhibited cell proliferation. Introducing constitutively activated RAC1 disrupted cell polarity and increased ROS levels, indicating that RAC1 is a crucial regulator that links cell polarity and ROS generation. We also linked monocyte infiltration with disruption of polarized acinar structure using a 3D co-culture system. Gain- and loss-of-function experiments demonstrated that increased ROS in non-polarized cells is necessary and sufficient to enhance monocyte recruitment. ROS also induced cytokine expression and NF-κB activity. These results suggest that increased ROS production in mammary epithelial cell leads to disruption of cell polarity and promotes monocyte infiltration.
The asymptotic closed-loop approach to predictive vector quantizer design with application in video coding (2001)

The basic vector quantization (VQ) technique employed in video coding belongs to the category of predictive vector quantization (PVQ), as it involves quantization of the (motion compensated) frame prediction error. It is well known that the design of PVQ suffers from fundamental difficulties, due to the prediction loop, which have an impact on the convergence and the stability of the design procedure. We propose an approach to PVQ design that enjoys the stability of open-loop design while it ensures ultimate optimization of the closed-loop system. The method is derived for general predictive quantization, and we demonstrate it on video compression at low bit rates, where it provides substantial improvement over standard open and closed loop design techniques. Further, the approach outperforms standard DCT-based video coding.

Considerations in the Design of Materials for Solar‐Driven Fuel Production Using Metal‐Oxide Thermochemical Cycles (2013)

With demand for energy increasing worldwide and an ever‐stronger case building for anthropogenic climate change, the need for carbon‐neutral fuels is becoming an imperative. Extensive transportation infrastructure based on liquid hydrocarbon fuels motivates development of processes using solar energy to convert CO 2 and H 2 O to fuel precursors such as synthesis gas. Here, perspectives concerning the use of solar‐driven thermochemical cycles using metal oxides to produce fuel precursors are given and, in particular, the important relationship between reactor design and material selection is discussed. Considering both a detailed thermodynamic analysis and factors such as reaction kinetics, volatility, and phase stability, an integrated analytical approach that facilitates material design is presented. These concepts are illustrated using three oxide materials currently receiving considerable attention: metal‐substituted ferrites, ceria, and doped cerias. Although none of these materials is “ideal,” the tradeoffs made in selecting any one of them are clearly indicated, providing a starting point for assessing the feasibility of alternative materials developed in the future.
Finite-Element Analysis of Semiconductor Devices: The FIELDAY Program (1981)

The FIELDAY program simulates semiconductor devices of arbitrary shape in one, two, or three dimensions operating under transient or steady-state conditions. A wide variety of physical effects, important in bipolar and field-effect transistors, can be modeled. The finite-element method transforms the continuum description of mobile carrier transport in a semiconductor device to a simulation model at a discrete number of points. Coupled and decoupled algorithms offer two methods of linearizing the differential equations. Direct techniques are used to solve the resulting matrix equations. Pre- and post-processors enable users to rapidly generate new models and analyze results. Specific examples illustrate the flexibility and accuracy of FIELDAY.
Key management for secure lnternet multicast using Boolean function minimization techniques (1999)

The Internet provides no support for privacy or authentication of multicast packets. However, an increasing number of applications require secure multicast services in order to restrict group membership and enforce accountability of group members. A major problem associated with the deployment of secure multicast delivery services is the scalability of the key distribution protocol. This is particularly true with regard to the handling of group membership changes, such as member departures and/or expulsions, which necessitate the distribution of a new session key to all the remaining group members. As the frequency of group membership changes increases, it becomes necessary to reduce the cost of key distribution operations. This paper explores the use of batching of group membership changes to reduce the frequency, and hence the cost, of key re-distribution operations. It focuses explicitly on the problem of cumulative member removal and presents an algorithm that minimizes the number of messages required to distribute new keys to the remaining group members. The algorithm is used in conjunction with a new multicast key management scheme which uses a set of auxiliary keys in order to improve scalability. In contrast to previous schemes which generate a fixed hierarchy of keys, the proposed scheme dynamically generates the most suitable key hierarchy by composing different keys. Our cumulative member removal algorithm uses Boolean function minimization techniques, and outperforms all other schemes known to us in terms of message complexity.
Autism Spectrum Disorder â€“ Advances in Genomics and Impact of Early Behavioral Intervention (2018)

Autism spectrum disorder is a developmental disÂ­order characterized by persistent deficits in social interaction and communication, as well as by restricted, repetitive patterns of behavior or activities. It is a complex polygenic disorder. It occurs due to altered gene-environmental interacÂ­tion. There are several single nucleotide polymorphisms associated with autism spectrum disorder. Copy number variations are detected in several autism spectrum disorder probands. Recent studies have found novel candidate genes and point mutations associated with this disorder. Abnormal synaptic homeostasis is found to be a factor for autism spectrum disorder. Several genes are the key regulators of synaptic plasticity. Rare de novo and inherited copy number variations have been implicated in the genetic factors. The key to successful management of autism spectrum disorder is early behavioral intervention. Infant at risk should be provided very early intervention before full syndrome is present. Parent training interventions have an important role in the management of these children. Early interventions will improve the intelligence, adaptive behavior as well as the social and communication skills of the children with autism spectrum disorder.
