MEMS-Switched, Frequency-Tunable Hybrid Slot/PIFA Antenna (2009)

A microelectromechanical systems (MEMS)-switched, frequency-tunable hybrid slot/planar inverted-F antenna (PIFA) is demonstrated. The antenna occupies a small printed circuit board (PCB) space and is capable of operating between 2 and 5 GHz with three digital tuning steps. The measured mismatch-corrected efficiency is better than 60% between 2 and 5 GHz. The specific absorption rate (SAR) for an input power of 100 mW is less than 0.45 W/kg averaged over 1 g of tissue and 0.31 over 10 g of tissue assuming a system duty cycle of 0.5.
Research on Online Quiz Scheme Based on Double-Layer Consortium Blockchain (2018)

The students' online quiz is a way to realize the informatization and modernization of higher education. To solve the problem that the scoring process is non-transparent, injustice and the final results are easy to be changed, an online quiz scheme based on Double-layer Consortium Blockchain is proposed. The scheme achieves the public verification of students' answers and the answer records cannot be tampered with but can be traced. Besides, group signature is used to solve the problem of anonymous abuse in blockchain applications. In addition, the storage pressure of sub-chains' nodes can be further reduced by adding the prime-chain's index to the sub-chains.
Video Summarization with Long Short-term Memory (2016)

We propose a novel supervised learning technique for summarizing videos by automatically selecting keyframes or key subshots. Casting the problem as a structured prediction problem on sequential data, our main idea is to use Long Short-Term Memory (LSTM), a special type of recurrent neural networks to model the variable-range dependencies entailed in the task of video summarization. Our learning models attain the state-of-the-art results on two benchmark video datasets. Detailed analysis justifies the design of the models. In particular, we show that it is crucial to take into consideration the sequential structures in videos and model them. Besides advances in modeling techniques, we introduce techniques to address the need of a large number of annotated data for training complex learning models. There, our main idea is to exploit the existence of auxiliary annotated video datasets, albeit heterogeneous in visual styles and contents. Specifically, we show domain adaptation techniques can improve summarization by reducing the discrepancies in statistical properties across those datasets.
Technical overview of the German program to develop superconducting AC generators (1983)

At the Technical University of Munich, a superconducting 320kVA generator has been taken into operation for experimental purposes. KWU and Siemens are running an extensive program to develop superconducting (SC) generators of commercial size. This development program is described in detail, and reports are given about the experimental work on three major components, namely the superconducting field winding, the cryogenic cooling system and the helium transfer equipment
Observation of multi-GeV breakdown thresholds in dielectric wakefield structures (2007)

An experiment designed to test the breakdown threshold of a dielectric subjected to the GV/m-scale electric-fields of an intense electron-beam has been completed. In this experiment at the final focus test beam (FFTB) facility, the 28.5 GeV SLAC electron beam was focused down and propagated through short fused-silica capillary-tubes with internal diameters of as little as 100 mum. The electric field at the inner surface of the tubes was varied from about 1 GV/m to 22 GV/m by adjusting the longitudinal compression of the electron bunch. We observed a sharp increase in optical emissions from the capillaries in the middle part of this surface field range which we believe indicates the transition between sustainable field levels and breakdown. If this initial interpretation is correct, the multi-GV/m surfaced fields that were sustained equate to on axis accelerating field of several GV/m.
Three-dimensional (3D) structure model and its parameters for poplar shelterbelts (2010)

The spatial functions of surface area density(vegetative surface area per unit canopy volume) and cubic density(vegetative volume per unit canopy volume) have been used as two three-dimensional(3D) structural descriptors for shelterbelt.The functions were defined by models as a general case.However,sub-models such as surface area,volume,and corresponding distributions were not explicitly defined for poplar trees,which are a dominant woody species in shelterbelts all over China,and this limits applications of the models in China and elsewhere.In order to define and develop these sub-models for shelterbelts,poplar trees were destructively sampled from multiple-row shelterbelts and then were measured for their surface area and volume.Using these measurements,we estimated parameters to define their equations explicitly.Based on the architecture and planting patterns of trees in shelterbelts,the distribution of the surface areas and volumes vertically and across the width for different tree heights were constructed for the three components of trunks,branches and leaves.Incorporating the defined equations into the models,we described the 3D structure of a multiple-row poplar shelterbelt.The results showed that,the spatial change in magnitude of surface area density(0.215-10.131 m2/m3) or cubic density(0.00007-0.04667 m3/m3) in shelterbelts is large and their distributions are not uniform.The assumption for boundary-layer flow modeling efforts that the 3D distribution of shelterbelt structure was uniform is not the case in field.The 3D structure model not only can be used to model the flow field as influenced by each tree component,but also can express the entire aerodynamic characteristics of a shelterbelt.The methodologies and equations that are developed in this study can be applied to estimate the 3D structure of a shelterbelt with a design similar to our studied poplar shelterbelts in terms of species composition and planting patterns.The fitted models can be used to describe the 3D aerodynamic structure of field shelterbelts.Furthermore,an improved description of shelterbelt structure has great potential to improve the simulation of boundary layer flows as influenced by that shelterbelt.Such insights can eventually be used to quantify the design of shelterbelt structure and/or adjustment for managing the function of shelterbelts and their effects on microclimate.
Variable-Configuration Resonator (VCR) with Three Diode-Laser End-Pumped Nd:YAG Rods (1997)

The maximum pump-power range for stable fundamentalmode operation of longitudinally pumped solid-state lasers depends only on material constants. The stability range was increased by developing a versatile and scale-able end-pumped high-power multi-Nd:YAG-rod laser resonator that exploits the enhanced stability of ring cavities. The stability properties of this variable-configuration resonator (VCR) led to the opportunity for a novel Q-switching technique.
Directed DNA Metallization (2006)

Genes of interest can be selectively metallized via the incorporation of modified triphosphates. These triphosphates bear functions that can be further derivatized with aldehyde groups via the use of click chemistry. Treatment of the aldehyde-labeled gene mixture with the Tollens reagent, followed by a development process, results in the selective metallization of the gene of interest in the presence of natural DNA strands.
The constituent equations of piezoelectric bimorphs (1991)

A brief review of applications of piezoelectric bimorphs is presented. The constituent equations which describe the behavior of piezoelectric bimorphs for various mechanical boundary conditions are derived. The internal energy density of infinitesimally small volume elements in thermodynamic equilibrium is calculated in the presence of a voltage on the electrodes, a clamped cantilever beam condition on one side of the beam and a set of three different classical boundary conditions on the other side of the beam. These are a mechanical moment M at the end of the beam, a force F perpendicular to the beam, applied at its tip, and a uniformly distributed body force p. The total internal energy content is calculated by integrating over the entire volume of the beam. Two different beam configurations are considered: parallel polarizations of the two adjoining elements of the beam with an internal electrode; and antiparallel orientation without an internal electrode. The canonical conjugate of the moment is calculated as the angular deflection at the tip of the beam α, while that of the force at the tip is the local vertical deflection δ. The canonical conjugate of the uniform load on the beam is found to be the volume displacement V of the beam. The canonical conjugate of the voltage across the electrodes is the charge on the electrodes. The equations are given in the direct form, with external parameters (M, V), (F, V), and (p, V) as independent variables and also in a linear combination with (M, F, p, V) as variables. These constituent equations can be used to calculate the behavior of the bimorph under any condition that can be described as a linear combination of forces at the tip, moments at the tip and uniform loads on the entire beam. This allows us to use the bimorph as a black box, without having to consider its internal movement or charges.
Simultaneous measurement of mode conversion coefficients and mode dependent losses in the frequency domain (1981)

A simplified method for the measurement of mode conversion coefficients and mode dependent losses is proposed. The method utilizes sinusoidally modulated light instead of optical pulses and is applied to step-index multimode fibers. The results obtained by frequency domain measurement agree satisfactorily with those obtained by time domain measurement. It is confirmed that frequency domain measurements make it simple to obtain mode conversion coefficients and mode dependent losses. Experiments also show that mode dependent losses in the fibers are roughly independent of the mode order, and that the dynamic equilibrium is attained after propagation over a few kilometers even in available step-index fibers.
Antibody transport and internalization into tumours. (1990)

Internalization of monoclonal antibody (MAb) conjugates is an important feature of tumour targeting, both with respect to the therapeutic action of substances coupled to the antibody and to retention of radionuclides. Problems of analysing internalization in vitro and in vivo, of manipulating internalization, and of evaluating the involvement of normal tissues are illustrated by recent experimental data and are discussed in the light of published evidence.
Boron Nitride Nanopores: Highly Sensitive DNA Single‐Molecule Detectors (2013)

The first electronic measurement of DNA translocation through ultrathin BN nanopores is demonstrated. BN nanopores show much higher detection sensitivity compared with SiN nanopores. BN has a spatial resolution as graphene. The ultrathin BN nanopores provide substantial opportunities in realizing high-spatial-sensitivity nanopore electrical devices for various applications.
Theoretical Study of the Oxidation of Nickel Thiolate Complexes by O<sub>2</sub> (1996)

Qualitative ab initio theory is used to compare the electronic structures of nickel dithiolate complexes and the monosulfinates arising from O2 oxidations. The results are used to examine the electronic factors involved in the reaction mechanism. The frontier molecular orbitals (FMOs) of the dithiolate complexes are dominated by contributions from S p orbitals. Upon oxidation, the FMOs are dominated by sulfinate O atoms. This is consistent with a mechanism involving nucleophilic attack on O2 by the thiolate S-donors and suggests that the reaction stops after the oxidation of a single S atom because of this change in electronic structure.

Tunable Capacitors with Programmable Capacitance-Voltage Characteristic (1998)

We report the design and fabrication of a mi cromechanical tunable capacitance device with a lithographically-programmable capacitance-voltage (C V) characteristic. Device prototypes utilizing a contact "zipping" actuator achieve a 25% tuning range with a linear C-V characteristic. Three significant results are described: (1) realization of a device with a large capac itive tuning range and programmable C-V device char acteristics, (2) development of a stable zipping actuator using fl at structures, and (3) development of an auto mated meshed simulation/optimization technique used to design the device.
Epidermal growth factor-mediated apoptosis of MDA-MB-468 human breast cancer cells. (1994)

MDA-MB-468 human breast cancer cells lack estrogen receptors, overexpress epidermal growth factor (EGF) receptors, and are growth inhibited by EGF. We show that treatment of MDA-MB-468 cells with EGF leads to inhibition of cell proliferation, fragmentation of DNA into nucleosomal oligomers, and the development of apoptotic morphology. This treatment is associated with increased expression of c-myc, c-fos, jun family members, and transforming growth factor beta 1 mRNA and with partial proteolytic cleavage of poly(ADP-ribose) polymerase and lamin B. The observation that EGF can mediate apoptosis in EGF receptor-overexpressing cells has important implications for clinical efforts directed at the EGF receptor.
The Evaluation of Specialized Cements (2002)

Abstract In recent years specialized cements have been developed for use in the oilfield. These cements have ranged from very lightweight to very heavy cements. They have included additives such as glass or ceramic beads to alter their properties. With an increased use of these cements, concerns have risen about the cement evaluation. Quite often the question is asked, "Can we evaluate these cements?" rather than, "How do we evaluate these cements?" This paper will discuss some logging techniques that can be used to evaluate these new cements. The desire to cement longer casing intervals without exceeding the formation fracture gradient has led to the use of very light weight cements. These cements have low acoustic impedance values that are not much higher than the acoustic impedance values of drilling fluids. The compressive strength of these cements can also vary significantly. Acoustic impedance and compressive strength are the properties that cement evaluation tools use to differentiate between the fluids and the solids in the casing formation annulus. To identify these differences it is critical that the proper logging techniques and input parameters are selected for the sonic and ultrasonic tools. A statistical analysis of acoustic impedance measurements from the ultrasonic tools has also proven to be valuable for the evaluation of these special cements. Examples from Alaska, and other areas where these types of cements are being used to solve difficult completion problems, will be shown to demonstrate the use of these cement evaluation techniques.
Role of GluK1 Kainate Receptors in Seizures, Epileptic Discharges, and Epileptogenesis (2014)

Kainate receptors containing the GluK1 subunit have an impact on excitatory and inhibitory neurotransmission in brain regions, such as the amygdala and hippocampus, which are relevant to seizures and epilepsy. Here we used 2-amino-3-(3-hydroxy-5-tert-butylisoxazol-4-yl) propanoic acid (ATPA), a potent and selective agonist of kainate receptors that include the GluK1 subunit, in conjunction with mice deficient in GluK1 and GluK2 kainate receptor subunits to assess the role of GluK1 kainate receptors in provoking seizures and in kindling epileptogenesis. We found that systemic ATPA, acting specifically via GluK1 kainate receptors, causes locomotor arrest and forelimb extension (a unique behavioral characteristic of GluK1 activation) and induces myoclonic behavioral seizures and electrographic seizure discharges in the BLA and hippocampus. In contrast, the proconvulsant activity of systemic AMPA, kainate, and pentylenetetrazol is not mediated by GluK1 kainate receptors, and deletion of these receptors does not elevate the threshold for seizures in the 6 Hz model. ATPA also specifically activates epileptiform discharges in BLA slices in vitro via GluK1 kainate receptors. Olfactory bulb kindling developed similarly in wild-type, GluK1, and GluK2 knock-out mice, demonstrating that GluK1 kainate receptors are not required for epileptogenesis or seizure expression in this model. We conclude that selective activation of kainate receptors containing the GluK1 subunit can trigger seizures, but these receptors are not necessary for seizure generation in models commonly used to identify therapeutic agents for the treatment of epilepsy.
Human Langerhans cells induce distinct IL-22-producing CD4 <sup>+</sup> T cells lacking IL-17 production (2009)

IL-22 is a cytokine that acts mainly on epithelial cells. In the skin, it mediates keratinocyte proliferation and epidermal hyperplasia and is thought to play a central role in inflammatory diseases with marked epidermal acanthosis, such as psoriasis. Although IL-22 was initially considered a Th17 cytokine, increasing evidence suggests that T helper cells can produce IL-22 even without IL-17 expression. In addition, we have shown the existence of this unique IL-22-producing T cell in normal skin and in the skin of psoriasis and atopic dermatitis patients. In the present study, we investigated the ability of cutaneous resident dendritic cells (DCs) to differentiate IL-22-producing cells. Using FACS, we isolated Langerhans cells (LCs; HLA-DR(+)CD207(+) cells) and dermal DCs (HLA-DR(hi)CD11c(+)BDCA-1(+) cells) from normal human epidermis and dermis, respectively. Both LCs and dermal DCs significantly induced IL-22-producing CD4(+) and CD8(+) T cells from peripheral blood T cells and naive CD4(+) T cells in mixed leukocyte reactions. LCs were more powerful in the induction of IL-22-producing cells than dermal DCs. Moreover, in vitro-generated LC-type DCs induced IL-22-producing cells more efficiently than monocyte-derived DCs. The induced IL-22 production was more correlated with IFN-gamma than IL-17. Surprisingly, the majority of IL-22-producing cells induced by LCs and dermal DCs lacked the expression of IL-17, IFN-gamma, and IL-4. Thus, LCs and dermal DCs preferentially induced helper T cells to produce only IL-22, possibly "Th22" cells. Our data indicate that cutaneous DCs, especially LCs, may control the generation of distinct IL-22 producing Th22 cells infiltrating into the skin.

Over-the-Top Content Delivery (2014)

In this tutorial we present state of the art and challenges ahead in over-the-top content delivery. It particular, the goal of this tutorial is to provide an overview of adaptive media delivery, specifically in the context of HTTP adaptive streaming (HAS) including the recently ratified MPEG-DASH standard. The main focus of the tutorial will be on the common problems in HAS deployments such as client design, QoE optimization, multi-screen and hybrid delivery scenarios, and synchronization issues. For each problem, we will examine proposed solutions along with their pros and cons. In the last part of the tutorial, we will look into the open issues and review the work-in-progress and future research directions.
Fast Predictive Oxygen Charge Control of a Diesel Engine (2007)

Every control system of a diesel engine tries to supply the combustion chamber with the mixture of fresh gas and recirculated exhaust gas adequate to the requested injection quantity. Usually, this mixture is expressed in particular by a combination of intake manifold pressure, measured locally, and fresh air flow measured at a substantial distance from the combustion chamber. As the amount of exhaust recirculation is subject to many disturbances and uncertainties, standard control approaches are not satysfying, especially during transients, and the emission targets are met essentially by reducing the dynamics of fuel injection by so called smoke maps. In this paper, we discuss the possibility to design an oxygen charge control which estimates the available oxygen amount in the intake manifold - after the mixture of fresh and recirculated exhaust gas - using an oxygen sensor. To reduce the effect of modeling errors or of bandwidth limitations, the comparison with the standard choice of variables is performed using data based multilinear models and an explicit MPC to compute the control signals. Comparisons performed on a production engine on a dynamic test bench confirm that the approach is able to provide a better oxygen control during transients.
Significant Interference with Hepatitis B Virus Replication by a Core-nuclease Fusion Protein (2001)

Hepatitis B virus (HBV), a small DNA containing virus that replicates via reverse transcription, causes acute and chronic B-type hepatitis in humans. The limited success of current therapies for chronic infection has prompted exploration of alternative strategies. Capsid-targeted viral inactivation is a conceptually powerful approach that exploits virion structural proteins to target a degradative enzyme specifically into viral particles. Its principal feasibility has been demonstrated in retroviral model systems but not yet for a medically relevant virus outside the retrovirus family. Recently, we found that C proximal fusion to the HBV capsid protein of the Ca(2+)-dependent nuclease (SN) from Staphylococcus aureus yields a chimeric protein, coreSN, that in Escherichia coli coassembles with the wild-type capsid protein into particles with internal SN domains. Here we show that, in HBV co-transfected human hepatoma cells, less than 1 coreSN protein per 10 wild-type core protein subunits reduced titers of enveloped DNA containing virions by more than 95%. The antiviral effect depends on both an enzymatically active SN and on the core domain. CoreSN does not block assembly of RNA containing nucleocapsids but interferes with proper synthesis of viral DNA inside the capsid, or leads to rapid DNA degradation. Our data suggest an intracellular nuclease activation that, owing to the characteristics of HBV morphogenesis, is nonetheless highly virus specific. HBV may therefore be particularly vulnerable to the capsid-targeted viral inactivation approach.
