Parameterized models for crosstalk analysis in high-speed interconnects (2009)

We present a new parametric macromodeling technique for lossy and dispersive multiconductor transmission lines (MTLs), that is suitable to interconnect modeling. It is based on a recently introduced spectral approach for the analysis of lossy and dispersive MTLs extended by utilizing the Multivariate Orthonormal Vector Fitting (MOVF) technique to build parametric macromodels in a rational form. They can handle design parameters, such as substrate or geometrical layout features, in addition to frequency. The presented technique is suited to generate state-space models and synthesize equivalent circuits, which can be easily embedded into conventional SPICE-like solvers. Parametric macromodels allow to carry out design space exploration, design optimization and crosstalk analysis efficiently. A numerical example validates the proposed approach in both frequency and time domain and is focused on the crosstalk analysis.
Differentiated security in wireless networks (2002)

This report presents a three step solution to the differentiated security and self-configuration problem in wireless network where users are able to come and go as they wish. Differentiated security is about giving different user's different access rights towards a surrounding infrastructure. Access rights can in some systems be bought and in others they may be related to a users location or real life status. Self-configuration is about minimizing the configuration effort needed by network users. First a generic architecture is presented, which provides an abstract solution without any requirements on specific techniques or tools. Thereafter a prototype specification and a prototype implementation are derived from the architecture. They show that the desired system is feasible and relatively easy to construct, using well known tools for resource discovery, security and address handling.
FIR Analog Filter Dependence of HCG-Based Hollow-Core Waveguides upon Varying of Waveguide Parameters (2011)

Personalized diversification of complementary recommendations with user preference in online grocery (2023)

Complementary recommendations play an important role in surfacing the relevant items to the customers. In the cross-selling scenario, some customers might present more exploratory shopping behaviors and prefer more diverse complements, while other customers show less exploratory (or more conventional) shopping behaviors and want to have a deep dive of less diverse types of complements. The existence of two distinct shopping behaviors reflects users' different shopping intents and requires complementary recommendations to be adaptable based on the user's shopping intent. Although many studies focus on improving the recommendations through post-processing techniques, such as user-item-level personalized ranking and diversification of recommendations, they fail to address such a requirement. First, many user-item-level personalization methods cannot explicitly model the preference of users in two types of shopping behaviors and their intent on the corresponding complementary recommendations. Second, most of the diversification methods increase the heterogeneity of the recommendations. However, users' intent on conventional complementary shopping requires more homogeneity of the recommendations, which is not explicitly modeled. The present study tries attempts to solve these problems by the personalized diversification strategies for complementary recommendations. To address the requirement of modeling heterogenized and homogenized complementary recommendations, we propose two diversification strategies, heterogenization and homogenization, to re-rank complementary recommendations based on the determinantal point process (DPP). We use transaction history to estimate users' intent on more exploratory or more conventional complementary shopping. With the estimated user intent scores and two diversification strategies, we propose an algorithm to personalize the diversification strategies dynamically. We demonstrate the effectiveness of our re-ranking algorithm on the publicly available Instacart dataset.
Efficient DSP Architecture for High-Quality Audio Algorithms (2005)

This paper presents specialized DSP instructions and their hardware architecture for high-quality audio algorithms, such as the MPEG-2/4 advanced audio coding (AAC), Dolby AC-3, MPEG-2 backward compatible (BC), etc. The proposed architecture is specially designed and optimized for the IMDCT (inverse modified discrete cosine transform), and Huffman decoding in the AAC decoding algorithm. Performance comparisons show a significant improvement compared with TMS320C62/spl times/ and ASDSP21060 for the IMDCT computation. Furthermore, the dedicated Huffman accelerator performs the decoding process in only one cycle. The proposed DPU (data processing unit) consists of 107,860 gates and achieves 150 MIPS.
An ultrasensitive spintronic strain‐gauge sensor and a spin‐MEMS microphone (2018)

Abstract This review provides the spintronic strain‐gauge sensor (Spin‐SGS) based on a magnetic tunnel junction (MTJ) with a high gauge factor in excess of 5000, which was realized by adopting a novel amorphous Fe‐B‐based sensing layer with high magnetostriction and low coercivity in a high magnetoresistance Mg‐O barrier MTJ. This review also provides a demonstration of novel “Spintronic MEMS (Spin‐MEMS) microphone,” in which a series of Spin‐SGSs are integrated onto a bulk micromachined diaphragm. The Spin‐MEMS microphone exhibits a signal‐to‐noise ratio (SNR) of 57 dB(A) due to the high strain sensitivity of the Spin‐SGSs.

Investigation of the strength development of autoclaved aerated concrete (2018)

Abstract Although the chemical reactions occurring throughout the production process of autoclaved aerated concrete (AAC) are well‐known today, the physicochemical stability of the greencake during its expansion is not fully understood. The order in which reactions occur during the greencake setting, the reaction speed, their impact on the temperature, the viscosity, or the bubble formation remain unclear. The objective of this research is to better understand the contribution of different factors such as the quality of raw materials like quicklime, cement, or sulfate carrier on the expansion and strength development of the AAC greencake, with a focus on the temperature development. The impact of the raw materials is investigated on the hydration or slaking of the quicklime and on the greencake growth, while the strength development of the stabilizing mineral paste is studied using rheology. It is shown that the temperature profile in the greencake is governing the stability during the greencake growth, and is impacted by the amount and nature of the raw materials used. External temperature control and/or wise choice of raw materials may thus allow for a fundamental revision of mix compositions.
Hodgkin Lymphoma in Adolescents Treated with Adult Protocols: An Analysis From the German Hodgkin Study Group (GHSG). (2009)

Abstract Abstract 719 Introduction: The standard of care for adolescent Hodgkin lymphoma (HL) patients is undefined, particularly the choice between adult and pediatric protocols. We thus analyzed and compared risk factors, outcome and incidence of secondary malignancies in adolescents and young adults treated within study protocols of the German Hodgkin Study Group (GHSG) to evaluate whether adolescents represent a distinct patient group. Patients and Methods: 3785 patients of all stages treated within the second (HD4-HD6, 1988-1993) and third (HD7-HD9, 1993-1998) trial generation of the GHSG were retrospectively analyzed. 557 patients were adolescents aged 15 to 20 and 3228 patients were young adults aged 21 to 45. Treatment consisted of chemo- and/or radiotherapy. Results: The risk factors large mediastinal mass (more than 1/3 of the maximum intrathoracic diameter) and involvement of three or more lymph node areas were more common in adolescents (30.2% vs. 20.9% and 67.7% vs. 58.7%, respectively, p&lt;.001). The incidence of other risk factors did not differ significantly between age groups. With a median follow-up of 81 months for freedom from treatment failure (FFTF) and 85 months for overall survival (OS), FFTF rates in both groups were comparable (p=.305) while adolescents had a superior OS (p=.008). 6-year FFTF estimates were 80.2% and 79.7%, 6-year OS estimates were 93.6% and 90.9% in adolescents and young adults, respectively. Young adults had a higher risk to develop secondary malignancies. Secondary malignancy rates were 1.6% (9 of 557) in adolescents and 3.1% (101 of 3228) in young adults with secondary hematological malignancies (AML/MDS, NHL) representing the majority of cases in both groups (6/9 in adolescents and 55/101 in young adults). Since adolescents differ from young adults in terms of cancer risk in the general population, standardized incidence ratio (SIR) and absolute excess risk (AER) per 100.000 person-years were calculated. The SIR was higher in adolescents (5.56 vs. 4.58) while the AER was higher in young adults (394 vs. 194). However, differences between age groups were not significant for both. Conclusions: There are only slight differences between adolescents and young adults regarding risk factors, outcome and incidence of secondary malignancies. Therefore, treatment with adult protocols can be considered effective and safe in adolescent HL patients. Disclosures: No relevant conflicts of interest to declare.
dg2pix: Pixel-Based Visual Analysis of Dynamic Graphs (2020)

Presenting long sequences of dynamic graphs remains challenging due to the underlying large-scale and high-dimensional data. We propose dg2pix, a novel pixel-based visualization technique, to visually explore temporal and structural properties in long sequences of large-scale graphs. The approach consists of three main steps: (1) the multiscale modeling of the temporal dimension; (2) unsupervised graph embeddings to learn low-dimensional representations of the dynamic graph data; and (3) an interactive pixel-based visualization to simultaneously explore the evolving data at different temporal aggregation scales. dg2pix provides a scalable overview of a dynamic graph, supports the exploration of long sequences of high-dimensional graph data, and enables the identification and comparison of similar temporal states. We show the applicability of the technique to synthetic and real-world datasets, demonstrating that temporal patterns in dynamic graphs can be identified and interpreted over time. dg2pix contributes a suitable intermediate representation between node-link diagrams at the high detail end and matrix representations on the low detail end.
Revisiting Heme Mechanisms. A Perspective on the Mechanisms of Nitric Oxide Synthase (NOS), Heme Oxygenase (HO), and Cytochrome P450s (CYP450s) (2008)

Despite the essential biological importance of reactions that involve heme, mechanisms of heme reactions in enzymes like nitric oxide synthase (NOS), heme oxygenase (HO), and cytochrome P450s (CYP450s) are still not well-understood. This Perspective on NOS, HO, and CYP450 mechanisms is written from the point of view of the heme chemistry. Steps in the classical heme catalytic cycle are discussed based on the specific environment within each of these enzymes. Elucidation of the mechanisms of NOS inactivation by some substrate analogues provides important mechanistic clues to the NOS catalytic mechanism. On the basis of mechanistic studies of NOS inactivation by amidine analogues of l-arginine and other previous mechanistic results, a new mechanism for NOS-catalyzed l-arginine NG-hydroxylation (the first half of the catalytic reaction) is proposed in this Perspective. The key step in the second half of the NOS catalytic reaction, the internal electron transfer between the substrate and heme, is discussed on the basis of mechanistic results of NOS inactivation by NG-allyl-l-arginine and the structures of the substrate intermediates. Elucidation of the mechanism of NOS inactivation by amidines, which leads to heme degradation, also provides important mechanistic implications for heme oxygenase-catalyzed heme catabolism. Focusing on the meso-hydroxylation step during inactivation of NOS by amidines as well as the HO-catalyzed reaction, the essential nature of the heme-oxygen species responsible for porphyrin meso-hydroxylation is discussed. Finally, on the basis of the proposed heme degradation mechanism during NOS inactivation and the HO-catalyzed reaction, the mechanism for the formation of the monooxygenated heme species in P450-catalyzed reactions is discussed.

Well-Placement Optimization in Heavy Oil Reservoirs Using a Novel Method of In Situ Steam Generation (2018)

Determination of optimal well locations plays an important role in the efficient recovery of hydrocarbon resources. However, it is a challenging and complex task. The objective of this paper is to determine the optimal well locations in a heavy oil reservoir under production using a novel recovery process in which steam is generated, in situ, using thermochemical reactions. Self-adaptive differential evolution (SaDE) and particle swarm optimization (PSO) methods are used as the global optimizer to find the optimal configuration of wells that will yield the highest net present value (NPV). This is the first known application, where SaDE and PSO methods are used to optimize well locations in a heavy oil reservoir that is recovered by injecting steam generated in situ using thermo-chemical reactions. Comparison analysis between the two proposed optimization techniques is introduced. On the other hand, laboratory experiments were performed to confirm the heavy oil production by thermochemical means. CMG STARS simulator is utilized to simulate reservoir models with different well configurations. The experimental results showed that thermochemicals, such as ammonium chloride along with sodium nitrate, can be used to generate in situ thermal energy, which efficiently reduces heavy-oil viscosity. Comparison of results is made between the NPV achieved by the well configuration proposed by the SaDE and PSO methods. The results showed that the optimization using SaDE resulted in 15% increase in the NPV compared to that of the PSO after 10 years of production under in situ steam injection process using thermochemical reactions.

Influenza Viruses Suitable for Studies in Syrian Hamsters (2022)

Several small animal models, including mice, Syrian hamsters, guinea pigs, and ferrets are used to study the pathogenicity, transmissibility, and antigenicity of seasonal and pandemic influenza viruses. Moreover, animal models are essential for vaccination and challenge studies to evaluate the immunogenicity and protective efficacy of new vaccines. However, authentic human influenza viruses do not always replicate efficiently in these animal models. Previously, we developed a high-yield A/Puerto Rico/8/34 (PR8-HY) vaccine virus backbone that conferred an increased virus yield to several seasonal influenza vaccines in eukaryotic cells and embryonated chicken eggs. Here, we show that this PR8-HY genetic backbone also increases the replication of several seasonal influenza viruses in Syrian hamsters compared to the authentic viruses. Therefore, the PR8-HY backbone is useful for animal studies to assess the biological properties of influenza viral HA and NA.
Electronic compass sensor (2006)

In this paper, we describe a new two respective three axis integrated IMC Hall-ASIC that can be used as a single chip electronic compass and applied in portable low cost electronic equipment like wrist watches and mobile phones. The electronic compass chip consists of ring shaped integrated ferromagnetic concentrators (IMC), a CMOS integrated circuit and an excitation coil manufactured by direct bonding onto the chip surface. The IMC Hall ASIC measures the two in-plane magnetic field components Bx and By and the vertical component Bz of the Earth's magnetic field. The IMC Hall sensor exhibits an excellent sensitivity of 8000 V/T for the X and Y axis which yields an in-plane heading accuracy of +/-1/spl deg/, whereas the field in the Z-axis is measured with a lower sensitivity of 800 V/T. The high sensitivity characteristics are obtained by integrating magnetic flux concentrators directly on the Hall-ASIC, which amplifies the Earth's magnetic field by a factor of 10. Furthermore, the compass sensors provides a low energy method to eliminate the perming effect (remnant field effect after subjecting to strong magnetic fields).
DETROIT: Data Collection, Translation and Sharing for Rapid Vehicular App Development (2022)

DETROIT is an open-source vehicle-agnostic end-to-end framework for vehicular data collection, translation and sharing that facilitates the rapid development of automotive apps. With vehicles becoming increasingly connected, unlocking sheer amounts of data from the in-vehicle network (IVN) can accelerate the development of many useful apps. Unlike existing commercial and academic solutions that can only access a restricted set of standardized emission-related sensor data and lack feasible data accessibility by third-party developers, DETROIT offers a convenient interface to develop apps which can access a broad range of powertrain-related sensors and car-body events thanks to crowd-sourcing vehicular translation tables by fully automated CAN bus reverse-engineering. DETROIT is developed with the objectives of simplicity, scalability, privacy and liability. To the best of our knowledge, this is the first end-to-end framework consisting of a frontend, backend and a developer portal to cover vehicular data collection, translation and sharing with app developers. Besides an extensive framework benchmark to show the light resource overhead and feasibility of DETROIT, we also have evaluated it by reimplementing two existing mobility apps from academia. Developers have reported that DETROIT offers high sensor fidelity, enhanced application flexibility, as well as low implementation complexity.
A Stress Gradient-enhanced Piezoelectric Actuator Composite (GEPAC) with Integrated Ultrasonic NDE Capability for Continuous Health Monitoring (2004)

Stress gradient-enhanced piezoelectric actuator composites (GEPACs) are unimorph, curved actuators that can be used as low-frequency actuators embedded, for instance, within an aircraft skin. The actuator is made of a thin PZT ceramic layer bonded between two composite layers with different coefficients of thermal expansion. These curved actuators provide large bending motion. Actuators have been manufactured with segmented upper electrodes so that they can also be used at ultrasonic frequencies to monitor continuously the integrity of the actuator itself. It is shown that the actuator can be used to detect interfacial defects such as debonding between the piezoelectric layer and the outer layers. The input signal is a one-cycle burst at 1 MHz. The time domain signals recorded experimentally are compared with predictions from a finite element model. It is shown that the presence of a debonding defect can convert a symmetric pulse into a primarily antisymmetric wave. A simple correlation technique is used to estimate the size of the debonding region.
