Exploring emotions and multimodality in digitally augmented puppeteering (2008)

Recently, multimodal and affective technologies have been adopted to support expressive and engaging interaction, bringing up a plethora of new research questions. Among the challenges, two essential topics are 1) how to devise truly multimodal systems that can be used seamlessly for customized performance and content generation, and 2) how to utilize the tracking of emotional cues and respond to them in order to create affective interaction loops. We present PuppetWall, a multi-user, multimodal system intended for digitally augmented puppeteering. This application allows natural interaction to control puppets and manipulate playgrounds comprising background, props, and puppets. PuppetWall utilizes hand movement tracking, a multi-touch display and emotion speech recognition input for interfacing. Here we document the technical features of the system and an initial evaluation. The evaluation involved two professional actors and also aimed at exploring naturally emerging expressive speech categories. We conclude by summarizing challenges in tracking emotional cues from acoustic features and their relevance for the design of affective interactive systems.

Silicon interposer: A versatile platform towards full-3D integration of wireless systems at millimeter-wave frequencies (2015)

A 60-GHz transceiver module fully integrated on silicon interposer technology is demonstrated for the first time. The module includes a 65-nm CMOS RFIC transceiver and two antennas (transmit, receive) in a very compact volume (6.5×6.5×0.6 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> ). The fabrication process is presented. The design and measurements of the antenna demonstrate very good performances with a good impedance matching over the 57-66 GHz band and a gain up to 5 dBi in a compact area. Data transmissions at a raw data rate of up to 7 Gbps at 80 cm range and 3.5 Gbps at 2 m range were demonstrated. As an evolution towards full-3D integration on silicon interposer, a novel cavity-less design using a High-Impedance Surface (HIS) antenna is proposed and experimentally validated. As a perspective for large interposers' integration (including multiple transceivers and antenna arrays), the impact the BGA array distribution on the assembly's thermos-mechanical reliability for the HIS and classical configurations is investigated using finite-element analysis and an experimental setup.
Minority carrier diffusion length extraction in Cu<sub>2</sub>ZnSn(Se,S)<sub>4</sub>solar cells (2013)

We report measurement of minority carrier diffusion length (Ld) for high performance Cu2ZnSn(S,Se)4 (CZTSSe) solar cells in comparison with analogous Cu(In,Ga)(S,Se)2 (CIGSSe) devices. Our Ld extraction method involves performing systematic measurements of the internal quantum efficiency combined with separate capacitance-voltage measurement. This method also enables the measurement of the absorption coefficient of the absorber material as a function of wavelength in a finished device. The extracted values of Ld for CZTSSe samples are at least factor of 2 smaller than those for CIGSSe samples. Combined with minority carrier lifetime (τ) data measured by time-resolved photoluminescence, we deduce the minority carrier mobility (μe), which is also relatively low for the CZTSSe samples.
Backward adaptation for low delay vector excitation coding of speech at 16 kbit/s (2003)

To attain a very-low-delay speech coder at 16 kb/s while maintaining a quality acceptable for the public switched telephone network, low delay vector excitation coding (LD-VXC) is introduced. Backward adaptation is used to track the spectral characteristics of the signal without requiring any buffering of the input speech, thereby allowing a very low delay to be achieved in an analysis-by-synthesis structure. The algorithm differs markedly from conventional VXC or CELP (code-excited linear prediction) coders due to the use of backward adaptive linear prediction for modeling the time-varying short- and long-term correlation of speech. The LD-VXC coder provides very good speech quality at 16 kb/s, moderate complexity, a delay of under 2 ms, and a gentle degradation of quality with transmission errors. The algorithm was submitted to the CCITT as a candidate for a future 16-kb/s speech coding standard.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Human MxA Protein Confers Resistance to Semliki Forest Virus and Inhibits the Amplification of a Semliki Forest Virus-Based Replicon in the Absence of Viral Structural Proteins (1998)

Mx proteins form a small family of interferon (IFN)-induced GTPases with potent antiviral activity against various negative-strand RNA viruses. To examine the antiviral spectrum of human MxA in homologous cells, we stably transfected HEp-2 cells with a plasmid directing the expression of MxA cDNA. HEp-2 cells are permissive for many viruses and are unable to express endogenous MxA in response to IFN. Experimental infection with various RNA and DNA viruses revealed that MxA-expressing HEp-2 cells were protected not only against influenza virus and vesicular stomatitis virus (VSV) but also against Semliki Forest virus (SFV), a togavirus with a single-stranded RNA genome of positive polarity. In MxA-transfected cells, viral yields were reduced up to 1,700-fold, and the degree of inhibition correlated well with the expression level of MxA. Furthermore, expression of MxA prevented the accumulation of 49S RNA and 26S RNA, indicating that SFV was inhibited early in its replication cycle. Very similar results were obtained with MxA-transfected cells of the human monocytic cell line U937. The results demonstrate that the antiviral spectrum of MxA is not restricted to negative-strand RNA viruses but also includes SFV, which contains an RNA genome of positive polarity. To test whether MxA protein exerts its inhibitory activity against SFV in the absence of viral structural proteins, we took advantage of a recombinant vector based on the SFV replicon. The vector contains only the coding sequence for the viral nonstructural proteins and the bacterial LacZ gene, which was cloned in place of the viral structural genes. Upon transfection of vector-derived recombinant RNA, expression of the beta-galactosidase reporter gene was strongly reduced in the presence of MxA. This finding indicates that viral components other than the structural proteins are the target of MxA action.
Measurements and analysis of PLL jitter caused by digital switching noise (2001)

When integrating analog and digital circuits onto a mixed-mode chip, power supply noise coupling is a major limitation on the performance of the analog circuitry. Several techniques exist for reducing the noise coupling, of which one of the cheapest is separating the power supply distribution networks for the analog and digital circuits. Noise coupling from a digital noise-generating circuit through the power supply/substrate into an analog phase-locked loop (PLL) is analyzed for three different power supply schemes. The main mechanisms for noise coupling are identified by comparing different PLLs and varying their bandwidths. It is found that the main cause of jitter strongly depends on the power supply configuration of the PLL. Measurements were done on mixed-mode designs in a standard 0.25-/spl mu/m digital CMOS process with a low-resistivity substrate. The same circuits were also implemented with triple-well processing for comparisons.
Systems workplace for endoscopic surgery (2000)

With the advent of minimally invasive surgery (MIS) a decade ago, the requirements for operating rooms (OR) and their equipment have been increased. Compared with conventional open surgery, the new endoscopic techniques require additional tools. Television systems, for video-assisted image acquisition and visualisation, including cameras, monitors and light systems, as well as insufflators, pumps, high-frequency units, lasers and motorised therapy units, are nowadays usually made available on carts during endoscopic surgery. In conjunction with a set of endoscopic instruments, these high-tech units allow new operating techniques to be performed. The benefit for patients has become clear in recent years; however, the technical complexity of OR has also increased considerably. To minimise this problem for the OR personnel, the MIS concept 'OR1' (Operating Room 1) was developed and implemented. OR1 is a fully functional and integrated multi-speciality surgical suite for MIS. The centrepieces of the OR1 are the Storz Communication Bus (SCB) and the advanced image and data archiving system (Aida) from Karl Storz, Tuttlingen, Germany. Both components allow monitoring, access and networking of the MIS equipment and other OR facilities, as well as the acquisition, storage and display of image, patient and equipment data during the endoscopic procedure. A central user interface allows efficient, simplified operation and online clinical images. Due to the system integration, the handling of complex equipment is considerably simplified, logistical procedures in the OR are improved, procedure times are shorter and, particularly noteworthy, operative risk can be reduced through simplified device operation.
Rapamycin antagonizes NF-κB nuclear translocation activated by TNF-α in primary vascular smooth muscle cells and enhances apoptosis (2006)

Several lines of evidence support the view that rapamycin inhibits NF-kappaB. TNF-alpha, a potent inducer of NF-kappaB, is released after artery injury (e.g., balloon angioplasty) and plays an important role in inflammation and restenosis. We investigated the effect of rapamycin on NF-kappaB activation and apoptosis in vascular smooth muscle cells (VSMCs) stimulated with TNF-alpha. Using EMSA, we found that TNF-alpha caused NF-kappaB nuclear translocation in VSMCs after 1 h of incubation. Rapamycin inhibited IkappaBalpha degradation, thereby preventing nuclear translocation. Activation of NF-kappaB was accompanied by an increase of Bcl-xL and Bfl-1/A1 proteins, detected by Western blot assay, whereas rapamycin prevented the TNF-alpha-induced enhancement of these antiapoptotic proteins. The extent of apoptosis of VSMCs exposed to TNF-alpha was significantly enhanced by rapamycin. The effect of rapamycin appeared to be independent of the phosphatidylinositol 3-kinase/Akt-protein kinase B survival pathway, because the phosphatidylinositol 3-kinase inhibitor wortmannin neither prevented IkappaBalpha degradation nor increased apoptosis of cells incubated with TNF-alpha. Finally, we demonstrate that the large immunophilin FK-506 binding protein FKBP51 is essential for TNF-alpha-induced NF-kappaB activation in VSMCs. Our findings show that rapamycin inhibits NF-kappaB activation and acts in concert with TNF-alpha in induction of VSMC apoptosis.
SiC MOSFET gate drive design considerations (2015)

The purpose of this paper is to provide guidance on how to design gate driver circuits for Silicon Carbide (SiC) MOSFETs. There are new commercially available SiC MOSFETs available in discrete and module packages which are much faster and more efficient than their traditional IGBT counterparts. To take full advantage of these benefits we need to understand the requirements for a new breed of gate drivers that are tailored to meet the unique drive and protection characteristics of SiC MOSFETs. Traditional IGBT based fault protection schemes such as desaturation (desat) detection can be implemented with some modifications to protect SiC MOSFETs. However, due to the higher switching speed of the new SiC devices, it is worth another look at all the design and implementation aspects of a good SiC MOSFET gate driver.
Asymptotic Stress Fields for Thermomechanically Loaded Cracks in FGMs (2007)

The problem of a stationary crack in functionally graded materials (FGM), subjected to a combination of thermal and mechanical loading is considered. An asymptotic analysis coupled with Westergaard's stress function approach is used to characterize the stress field around the crack tip. Thermal and mechanical properties (e.g., elastic modulus, coefficient of thermal expansion, and thermal conductivity) are assumed to vary exponentially. The crack is assumed to be inclined to the direction of the property gradation. The thermal loading is taken to be a uniform heat flow in a direction inclined to the crack. The principal of superposition from linear elasticity is used to solve the problem, whereby the problem is divided into a number of subproblems. The first four terms in the expansion of the stress field are derived to explicitly bring out the influence of nonhomogeneity on the structure of the stress field. It is observed that the presence of heat flow produced no additional singularity and hence the classical inverse square root singularity still prevails around the crack tip. Using these stress field contours of constant maximum shear stress are generated and the effect of thermal loading on the crack-tip stress field is discussed.
Hyperalgesia induced in the rat by the amino-terminal octapeptide of nerve growth factor. (1991)

Nerve growth factor (NGF) in the mouse submandibular gland undergoes cleavage of its amino-terminal octapeptide when salivation is induced by epinephrine. The significance of this event is uncertain; cleaved NGF demonstrates bioactivity and no function has been attributed to the octapeptide produced (NGF-OP; Ser-Ser-Thr-His-Pro-Val-Phe-His). Enzyme inhibition studies indicating structural relatedness of NGF-OP and bradykinin (BK) prompted us to determine whether NGF-OP would elicit BK-like actions. We found that like BK, NGF-OP induced a decrease in mechanical nociceptive threshold (i.e., produced hyperalgesia) in the hairy skin of the rat. This effect was dose-dependent and sequence-specific; like BK it was attenuated by sympathectomy and indomethacin pretreatment. However, NGF-OP actions appeared to be distinct from those for BK in that tissue injury was required for NGF-OP to induce hyperalgesia. Furthermore, we found no evidence that NGF-OP bound to or activated BK receptors. Our data indicate that NGF-OP is a distinct mediator of hyperalgesia. We suggest that NGF-OP alters pain threshold in the injured target regions of NGF-responsive neurons.
IVUS elastography: a potential identifier of vulnerable atherosclerotic plaque (2002)

Rupture of atherosclerotic plaques is associated with acute myocardial infarction and unstable angina pectoris. Previously, plaque rupture has been associated with morphological features. In this study, the potential of intravascular elastography to detect stress concentrations that may indicate plaque vulnerability is investigated. Intravascular echograms and elastograms of excised human femoral arteries were determined using a custom made set-up. Next, sections were stained with picrosirius red and alpha-actin to counterstain collagen and smooth muscle cells (SMC), respectively. Human macrophage antibody staining was performed using anti-CD68 antibodies. Initial results of these experiments show that the strain in fatty tissue is higher than the strain in fibrous material. Furthermore, a plaque with all markers for plaque vulnerability revealed high strain levels at the vulnerable region within the plaque near the luminal border. These preliminary in vitro experiments indicate the potential of intravascular elastography to characterise different plaque components and to identify stress concentrations, one of the main indicators of plaque vulnerability. Additional validation studies will be required to evaluate the sensitivity and specificity of this technique.
Substrate-Directable Heck Reactions with Arenediazonium Salts. The Regio- and Stereoselective Arylation of Allylamine Derivatives and Applications in the Synthesis of Naftifine and Abamines (2011)

The palladium-catalyzed, substrate-directable Heck-Matsuda reaction of allylamine derivatives with arenediazonium salts is reported. The reaction proceeds under mild conditions, with excellent regio- and stereochemical control as a function of coordinating groups present in the allylamine substrate. The distance between the olefin moiety and the carbonylic system seems to play a key role regarding the regiocontrol. The method presents itself as robust, as simple to carry out, and with wide synthetic scope concerning the allylic substrates and the type of arenediazonium employed. The synthetic potential of the method is illustrated by the short total syntheses of the bioactive compounds naftifine, abamine, and abamine SG.
Exploring the deployment and adoption of RFID-enabled retail promotions management (2010)

This paper presents the development and deployment of an RFID-enabled system supporting promotions management. The system provides both back-end functionality to supply chain partners by measuring promotions effectiveness and front-end functionality to consumers by providing personalized selection of alternative promotion gifts. We report the system design and implementation, and discuss our experiences and lessons learned during the system deployment in two stages. The study reveals that deployment of RFID services in the retail context presents a number of technology and individual challenges in the form that require special treatment. These challenges refer to accurate readability of products, handling of exception events, health concerns, and consumer privacy. The study proposes specific implementation solutions for each challenge. We also performed a field study in a Greek retail outlet which revealed that shoppers evaluated more favorably the RFID augmented promotion management method compared to traditional methods. In terms of market acceptance, the results of a workshop with retailers and suppliers showcased that although the service provides multiple benefits to supply chain operations, factors related to cost, consumer privacy, and current maturity of RFID technology still prohibit the service's wide adoption by the industry. Finally, the results of a cost-benefit analysis indicate that the investment is financially viable, under certain assumptions, and breaks even after 3 years. Given the contextual details of the study, the lessons learned and the proposed deployment strategy may guide developers and organizations aspiring to adopt RFID to modify their strategies accordingly.
Laying Out Graphs Using Queues (1992)

The problem of laying out the edges of a graph using queues is studied. In a k-queue layout, vertices of the graph are placed in some linear order and each edge is assigned to exactly one of the k queues so that the edges assigned to each queue obey a first-in/first-out discipline. This layout problem abstracts a design problem of fault-tolerant processor arrays, a problem of sorting with parallel queues, and a problem of scheduling parallel processors. A number of basic results about queue layouts of graphs are established, and these results are contrasted with their analogues for stack layouts of graphs (the book-embedding problem). The 1-queue graphs (they are almost leveled-planar graphs) are characterized. It is proved that the problem of recognizing 1-queue graphs is NP-complete. Queue layouts for some specific classes of graphs are given. Relationships between the queuenumber of a graph and its bandwidth and separator size are presented. An apparent tradeoff between the queuewidth and the number of queues allowed in layouts of complete binary trees is indicated.

Finally the present status and future needs discussed.
High Performance Asymmetric Supercapacitors Based on Dual Phosphorus (P) and Nitrogen (N) co-Doped Carbon and Graphene-Polyaniline Electrodes (2017)

We report an asymmetric type hybrid supercapacitor device with ultrahigh-energy density by employing a dual phosphorus and nitrogen co-doped carbon (PNDC) and a graphene (G)–polyaniline (PANI) nanocomposite electroactive electrodes. Dual-doped carbon is synthesized by the microwave assisted technique and G-PANI was synthesized by the chemical oxidative polymerization technique. An asymmetric PNDC/G-PANI electrodes with ionic liquids (IL) as electrolytes in supercapacitor are found capable of increasing the operating voltage up to 4 V and electrodes with aqueous electrolytes in supercapacitor are capable of increasing the operating voltage up to 2 V. The size-uniform porous nanostructures of PNDC and G-PANI provide a continuous electron pathways and facilitate short ionic transportation process. Further, IL increases the wettability of the electrodes and exhibited ultra-high energy density of 114 Wh/kg and 13.7 kW/kg power density at a 2 A/g current density. Therefore, the asymmetric type hybrid supercapacitor based on G-PANI nanocomposite and microwave assisted PNDC electrodes is a cost effective ultra-high energy density supercapacitor with high rate capability.
Metabolic control of insulin gene expression and biosynthesis (1991)

The regulation of insulin production by pancreatic p cells is mediated by a number of circulating nutrients and hormones, of which glucose is the predominant physiological stimulus. Over short periods of 1-2 h glucose regulates. insulin biosynthesis mainly at the level of translation This is in keeping with the requirement to rapidly replenish insulin stores, secreted in response to elevated circulating glucose levels following food intake. In addition to the acute effect on translation, glucose also affects insulin mRNA production and stability over longer periods (Brundstedt & Chan, 1982; Nielsen et al. 1985; Welsh et al. 1985). Here we will describe some recent experiments, which have increased our understanding of how these transcriptional and translational processes respond to external stimuli.
The Impact of Technology Node Scaling on nMOS SPDT RE Switches (2008)

This work presents a comparison of three single-pole double-throw (SPDT) nMOS RF switches implemented in commercially available Si-based 180, 130, and 90 nm technologies. In addition, a new series-shunt switch is presented that offers a means to improve switch isolation. Measured results of these RF switches demonstrates how technology node scaling impacts RF switch design and provides insight into the complicated trade-offs between insertion loss, isolation, and linearity.
