The study on the low profile array with high gain (2009)

In this paper, a novel quasi-dipole antenna together with a new type of microstrip feed network is presented. The antenna is realized by stacking two substrate layers which are separated by a common ground board. The quasi-dipole, of which the two arms can be of any reasonable shape, are printed on double sides of the upper substrate and fed by a coaxial cable. The antenna exhibits a small size and a good overall performance in terms of wide band, high gain, low cross polarization level and low backward radiation. To verify the design, the elements are used to form a 4 × 8 array by designing a novel microstrip feed network, in which quasi-orthogonal feed lines are employed and simplified by combining parallel and serial feeding technologies. Excellent correlation between the simulated and measured results shows that it is a good candidate in large array antennas for satellite communication applications.
VBPR: Visual Bayesian Personalized Ranking from Implicit Feedback (2016)

Modern recommender systems model people and items by discovering or `teasing apart' the underlying dimensions that encode the properties of items and users' preferences toward them. Critically, such dimensions are uncovered based on user feedback, often in implicit form (such as purchase histories, browsing logs, etc.); in addition, some recommender systems make use of side information, such as product attributes, temporal information, or review text.However one important feature that is typically ignored by existing personalized recommendation and ranking methods is the visual appearance of the items being considered. In this paper we propose a scalable factorization model to incorporate visual signals into predictors of people's opinions, which we apply to a selection of large, real-world datasets. We make use of visual features extracted from product images using (pre-trained) deep networks, on top of which we learn an additional layer that uncovers the visual dimensions that best explain the variation in people's feedback. This not only leads to significantly more accurate personalized ranking methods, but also helps to alleviate cold start issues, and qualitatively to analyze the visual dimensions that influence people's opinions.
Vision-based Landing Site Evaluation and Trajectory Generation Toward Rooftop Landing (2014)

Autonomous landing is an essential function for micro air vehicles (MAVs) for many scenarios. We pursue an active perception strategy that enables MAVs with limited onboard sensing and processing capabilities to concurrently assess feasible rooftop landing sites with a vision-based perception system while generating trajectories that balance continued landing site assessment and the requirement to provide visual monitoring of an interest point. The contributions of the work are twofold: (1) a perception system that employs a dense motion stereo approach that determines the 3D model of the captured scene without the need of geo-referenced images, scene geometry constraints, or external navigation aids; and (2) an online trajectory generation approach that balances the need to concurrently explore available rooftop vantages of an interest point while ensuring confidence in the landing site suitability by considering the impact of landing site uncertainty as assessed by the perception system. Simulation and experimental evaluation of the performance of the perception and trajectory generation methodologies are analyzed independently and jointly in order to establish the efficacy of the proposed approach.
Embedded 5 V-to-3.3 V voltage regulator for supplying digital IC's in 3.3 V CMOS technology (1998)

A fully integrated 5 V-to-3.3 V supply voltage regulator for application in digital IC's has been designed in a 3.3 V 0.5 /spl mu/m CMOS process. The regulator is able to deliver peak current transients of 300 mA, while the output voltage remains within a margin of 10% around the nominal value. The circuit draw's a static quiescent current of 750 /spl mu/A during normal operation, and includes a power-down mode with only 10 /spl mu/A current consumption. The die area is 1 mm/sup 2/, and can be scaled proportional to the maximum peak current. Special precautions have been taken to allow 5 V in the 3.3 V process.
Mapping Quantum Circuits to IBM QX Architectures Using the Minimal Number of SWAP and H Operations (2019)

The recent progress in the physical realization of quantum computers (the first publicly available ones---IBM's QX architectures---have been launched in 2017) has motivated research on automatic methods that aid users in running quantum circuits on them. Here, certain physical constraints given by the architectures which restrict the allowed interactions of the involved qubits have to be satisfied. Thus far, this has been addressed by inserting SWAP and H operations. However, it remains unknown whether existing methods add a minimum number of SWAP and H operations or, if not, how far they are away from that minimum---an NP-complete problem. In this work, weaddress this by formulating the mapping task as a symbolic optimization problem that is solved using reasoning engines like Boolean satisfiability solvers. By this, we do not only provide a method that maps quantum circuits to IBM's QX architectures with a minimal number of SWAP and H operations, but also show by experimental evaluation that the number of operations added by IBM's heuristic solution exceeds the lower bound by more than 100% on average. An implementation of the proposed methodology is publicly available at http://iic.jku.at/eda/research/ibm_qx_mapping.
Preoperative hCGβ and CA 72‐4 are prognostic factors in gastric cancer (2004)

In gastric cancer, the role of tumour markers in assessment of prognosis is unconfirmed. In our study, we evaluated the prognostic significance of serum tumour markers carcinoembryonic antigen (CEA), CA 19-9, CA 72-4, CA 242 and free beta subunit of human chorionic gonadotropin (hCGbeta) in gastric cancer. Preoperative serum samples were obtained from 146 patients with gastric cancer, including 29 with stage I, 11 with stage II, 42 with stage III and 64 patients with stage IV cancer. Quantitation of CEA, CA 19-9, CA 72-4 and CA 242 in serum was performed with commercial assays. HCGbeta was measured with an in-house immunofluorometric assay based on monoclonal antibodies specific for the free beta-subunit of hCG. Survival analysis was performed with Kaplan-Meier life-tables and log-rank test, and with multivariate Cox regression analysis. Disease-specific cumulative 2-year survival rate was 40%. Serum levels of CEA, CA 72-4, CA 242 and hCGbeta showed significant correlation with stage (p<0.027); for CA 19-9 the association was of borderline significance (p=0.056). Of the studied markers, CA 19-9, CA 72-4, CA 242 and hCGbeta were found to be prognostic factors in univariate analysis (p< 0.022). In multivariate analysis, stage had the statistically most significant association with prognosis followed by hCGbeta, tumour histology according to the Laurén classification and by CA 72-4. In gastric cancer, tumour markers hCGbeta and CA 72-4 are independent prognostic factors in addition to stage and histological type of the tumour.
Atomic Layer Deposition of W:Al<sub>2</sub>O<sub>3</sub>Nanocomposite Films with Tunable Resistivity (2013)

Abstract Nanocomposite tungsten‐aluminum oxide (W:Al 2 O 3 ) thin films were prepared by atomic layer deposition (ALD) using tungsten hexafluoride (WF 6 ) and disilane (Si 2 H 6 ) for the W ALD and trimethyl aluminum (TMA) and H 2 O for the Al 2 O 3 ALD. Quartz crystal microbalance (QCM) measurements performed using various W cycle percentages revealed that the W ALD inhibits the Al 2 O 3 ALD and vice versa. Despite this inhibition, the relationship between W content and W cycle percentage was close to that predicted by theoretical calculations based on the growth per cycle values of binary compounds. Depth profiling XPS showed that the (W:Al 2 O 3 ) films were uniform in composition and contained Al, O, and metallic W as expected, but also included significant F and C. Cross‐sectional TEM revealed the composite film structure to be metallic nanoparticles (∼1 nm) embedded in an amorphous matrix. The resistivity of these composite films could be tuned in the range of 10 12 –10 8 Ω cm by adjusting the W cycle percentage between 10% and 30%W. These films have applications in electron multipliers as well as electron and ion optics.
Acute Loss of miR-221 and miR-222 in the Atherosclerotic Plaque Shoulder Accompanies Plaque Rupture (2015)

Atherosclerotic plaque rupture is accompanied by a loss of miR-221 and miR-222 and an increase in p27Kip1 mRNA expression in the plaque shoulder, suggesting an association between these miRNAs and atherosclerotic plaque stability.
Invariant geometry of spin-glass states (1987)

We study how the geometry of spin-glass states changes under redefinitions of the metric. We show that in mean-field theory the property of ultrametricity is robust. We present numerical evidence suggesting that in the more realistic D=2 and D=3 spin-glass models a stronger result may hold, namely that the choice of metric is to a large extent unique.
Phosphopeptide enrichment by IEF (2006)

In our efforts to improve the identification of phosphopeptides by MS we have used peptide IEF on IPG strips. Phosphopeptides derived from trypsin digests of single proteins as well as complex cellular protein mixtures can be enriched by IEF and recovered in excellent yields at the acidic end of an IPG strip. IPG peptide fractionation in combination with MS/MS analysis has allowed us to identify phosphopeptides from tryptic digests of a cellular protein extract.
New liquid polysulfide polymer terminated with silyl group (2004)

Abstract The terminal SH of liquid polysulfide polymer was capped with a silyl group. This polymer was hydrolyzed immediately by moisture at ambient temperature and returned to the original polymer. The compounds of this new polymer and the various curing agents of the conventional polysulfide polymer became moisture curable and of use as one‐component sealants and adhesives. The curing speed of these compounds is very fast compared with that of not only conventional one‐component polysulfide sealants, by more than three times, but also of other one‐component sealants at 20°C under 30% humidity. Their storage stability is good. Their cured products showed physical properties comparable to those of the two‐component polysulfide compounds. In particular, the compound of this polymer and isocyanate prepolymer showed good elasticity and good weatherability. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 93: 2642–2649, 2004
Somatic gene transfer into the lactating ovine mammary gland (2002)

The ovine mammary gland turned out to be a very well suited as a model system for evaluation and optimization of various gene transfer protocols.
Performance Characteristics of the COBAS AMPLICOR Hepatitis C Virus MONITOR Test, Version 2.0 (2000)

We evaluated the performance characteristics of the COBAS AMPLICOR Hepatitis C Virus (HCV) MONITOR Test, version 2.0. Dilution studies using patient specimens demonstrated a lower limit of detection of 1,000 copies per milliliter. The assay was linear from 1,000 to 1 million HCV RNA copies per milliliter. Within-run precision and between-run precision were acceptable (approximately 0.100 and 0.14 SD for log10 [copies per milliliter]). A comparison of this version of the test (y), with the manual AMPLICOR HCV MONITOR Test, version 1.0 (x), yielded the following Deming regression equation: y = 1.004(+/- 0.04)x + 0.654(+/- 0.22); Sy/x¿D = 0.336; n = 92; r2 = 0.846; r = 0.920. Further comparison of the COBAS version 2.0 assay (x) with the QUANTIPLEX HCV bDNA Test (y) yielded the following Deming regression equation: y = 0.943 (+/- 0.130)x + 0.473 (+/- 0.717); Sy/x¿D = 0.194; n = 26; r2 = 0.600; r = 0.774. Version 2.0 detected the spectrum of HCV genotypes better than version 1.0.
Bispecific F(ab′γ)<sub>3</sub> antibody derivatives for redirecting unprimed cytotoxic T cells (1991)

Bispecific F(ab'gamma)3 derivatives have been constructed by selective coupling of monoclonal antibody Fab'gamma fragments, using the cross-linker o-phenylenedimaleimide attached to hinge-region sulfhydryl groups. All the derivatives were designed to redirect the cytotoxic activity of circulating human T lymphocytes, via their CD2, CD3 or CD5 molecules, against 51Cr-labeled chicken red blood cells (CRBC) or the human lymphoblastoid cell line, Namalwa. The composition of F(ab'gamma)3 molecules was controlled by the selection of Fab'gamma for initial attachment of cross-linker, allowing production of derivatives with either two anti-effector and one anti-target Fab'gamma arms or vice versa. Bispecific F(ab'gamma)3 derivatives, recruiting peripheral blood lymphocytes (PBL) via CD3 as effectors against CRBC, gave titers in redirected cellular cytotoxicity assays which were consistently 25-100 times higher than those given by an equivalent F(ab'gamma)2 reagent, with full activity being retained down to antibody concentrations of 1 ng/ml. The allocation of valencies--two anti-target/one anti-effector or the converse--was not important in determining the increase in titer. No significant lysis was seen when recruiting PBL via CD2 or CD5. It was notable that these CD3-specific derivatives yielded good tumor-cell lysis when using fresh, unprimed PBL as effectors. The increased activity over a bispecific F(ab'gamma)2 was apparent both in titer and the maximum level of lysis achieved. Blocking studies with excess Fab'gamma suggested that the potency of F(ab'gamma)3 derivatives lie in the strength of bridging between effector and target cells. This high avidity contact could favor metabolic activation in either the target or effector cell, or could increase the efficiency of lytic machinery already triggered.
Randomized Phase III Study Comparing Paclitaxel/Cisplatin/ Gemcitabine and Gemcitabine/Cisplatin in Patients With Locally Advanced or Metastatic Urothelial Cancer Without Prior Systemic Therapy: EORTC Intergroup Study 30987 (2012)

The addition of paclitaxel to GC provides a higher response rate and a 3.1-month survival benefit that did not reach statistical significance. Novel approaches will be required to obtain major improvements in survival of incurable urothelial cancer.
Unique block molecules based on glycerol skeleton as C‐3 building blocks for liquid crystals formation by self‐assembly and their future potential for the “nano‐chemistry” (2003)

Abstract Studies on design of liquid crystalline block molecules with non‐conventional mesophase morphoplogies have been proposed by Tschierske and co‐workers. These block molecules have a rigid core, a lateral substituent, and an alkyl chain segmenting blocks from each other. Related to this, diglyceryl alkyl ethers found by us have glycerol as a rigid core, a lateral substituent, and an alkyl chain similar to the Tschierske design. These two cases are compared with each other with regard to the relationship between the molecular structure and the liquid crystalline morphologies and other properties. Recently, new soft materials suitable for liquid crystals exhibiting self‐assembly of phase‐segregated structures have been designed. Typical examples of such “block” molecules containing glycerol having a C‐3 building block include: (i) undecyl‐glycerylether‐ modified siloxane derivatives with a siloxane segment as the rigid core and alkyl chains with 2, 3‐dihydroxypropoxy group as a hydrophilic group at a lateral or terminal position of the siloxane segment; (ii) novel hyper branched dendrimers forming the basis of polyglycerol nanocapsules with a core‐shell molecular architecture; (iii) carbon nanotubes based on cyclodextrins (CDs); (iv) polymerizable amphiphilic diacetylene‐containing phospholipids suitable for construction of functional nanocomposites. This is done by self‐assembly and polymerization of diacetylene creating a “block molecular structure” with a polyacetylene chain as a rigid core segment, the lipid headgroups as the hydrophilic segment, and terminal flexible alkyl chains. On the basis of these results, future potential of block molecules as a soft building material for liquid crystalline structures was discussed.
BOX: Browsing objects in XML (2000)

The latest Internet markup languages support the representation of structured information and vector graphics. In this paper we describe how these languages can be used to publish software engineering diagrams on the Internet. We introduce BOX, a portable, distributed and interoperable approach to browsing UML models with off-the-shelf technology. Our approach to browsing UML models leverages XML and related specifications, such as the Document Object Model (DOM), the XML Metadata Interchange (XMI) and the Vector Markup Language (VML). BOX translates a UML model that is represented in XMI into VML. VML can be directly displayed in Internet browsers, such as Microsoft's Internet Explorer 5. BOX enables software engineers to access and review UML models without the need to purchase licenses of tools that produced the models. BOX has been successfully evaluated in two industrial case studies. The case studies used BOX to make extensive domain and enterprise object models available to a large number of stakeholders over corporate intranets and the Internet. We show how XML and the BOX architecture can be applied to other software engineering notations. We also argue that the approach taken in BOX can be applied to other domains that have already started to adopt XML and have a need for graphic representation of XML information. These include browsing gene sequences, chemical molecule structures and conceptual knowledge representations. Copyright © 2000 John Wiley & Sons, Ltd.
New Approaches for Bacteriotherapy: Prebiotics, New-Generation Probiotics, and Synbiotics (2015)

The gut microbiota has a significant role in human health and disease. Dysbiosis of the intestinal ecosystem contributes to the development of certain illnesses that can be reversed by favorable alterations by probiotics. The published literature was reviewed to identify scientific data showing a relationship between imbalance of gut bacteria and development of diseases that can be improved by biologic products. The medical conditions vary from infectious and antibiotic-associated diarrhea to obesity to chronic neurologic disorders. A number of controlled clinical trials have been performed to show important biologic effects in a number of these conditions through administration of prebiotics, probiotics, and synbiotics. Controlled clinical trials have identified a limited number of prebiotics, probiotic strains, and synbiotics that favorably prevent or improve the symptoms of various disorders including inflammatory bowel disease, irritable bowel syndrome, infectious and antibiotic-associated diarrhea, diabetes, nonalcoholic fatty liver disease, necrotizing enterocolitis in very low birth weight infants, and hepatic encephalopathy. Studies have shown that probiotics alter gut flora and lead to elaboration of flora metabolites that influence health through 1 of 3 general mechanisms: direct antimicrobial effects, enhancement of mucosal barrier integrity, and immune modulation. Restoring the balance of intestinal flora by introducing probiotics for disease prevention and treatment could be beneficial to human health. It is also clear that significant differences exist between different probiotic species. Metagenomics and metatranscriptomics together with bioinformatics have allowed us to study the cross-talk between the gut microbiota and the host, furthering insight into the next generation of biologic products.
Gene Expression in Temporal Lobe Epilepsy (2007)

Gene Expression in Temporal Lobe Epilepsy Is Consistent with Increased Release of Glutamate by Astrocytes. Lee TS, Mane S, Eid T, Zhao H, Lin A, Guan HZ, Kim JH, Schweitzer J, King-Stevens D, Weber P, Spencer SS, Spencer DD, de Lanerolle NC. Mol Med . 2007;13( 1 2 ):1–13. Patients with temporal lobe epilepsy (TLE) often have a shrunken hippocampus that is known to be the location in which seizures originate. The role of the sclerotic hippocampus in the causation and maintenance of seizures in temporal lobe epilepsy (TLE) has remained incompletely understood despite extensive neuropathological investigations of this substrate. To gain new insights and develop new testable hypotheses on the role of sclerosis in the pathophysiology of TLE, the differential gene expression profile was studied. To this end, DNA microarray analysis was used to compare gene expression profiles in sclerotic and non-sclerotic hippocampi surgically removed from TLE patients. Sclerotic hippocampi had transcriptional signatures that were different from non-sclerotic hippocampi. The differentially expressed gene set in sclerotic hippocampi revealed changes in several molecular signaling pathways, which included the increased expression of genes associated with astrocyte structure (glial fibrillary acidic protein, ezrin-moesin-radixin, palladin), calcium regulation (S100 calcium binding protein beta, chemokine (C-X-C motif) receptor 4) and blood-brain barrier function (Aquaaporin 4, Chemokine (C-C- motif) ligand 2, Chemokine (C-C- motif) ligand 3, Plectin 1, intermediate filament binding protein 55kDa) and inflammatory responses. Immunohistochemical localization studies show that there is altered distribution of the gene-associated proteins in astrocytes from sclerotic foci compared with non-sclerotic foci. It is hypothesized that the astrocytes in sclerotic tissue have activated molecular pathways that could lead to enhanced release of glutamate by these cells. Such glutamate release may excite surrounding neurons and elicit seizure activity.
Optical phonon modes and crystal structure of NaLaF4 single crystals (2006)

Polarized Raman scattering and infrared reflectivity measurements have been used to investigate the crystal structure of Czochralski-grown NaLaF4 single crystals. The phonon symmetries, the simultaneous presence of polar modes in the infrared and Raman spectra, as well as the observation of piezoelectric resonance, helped us to identify the P6¯ group as the correct one for this crystal. This material belongs to a family of sodium lanthanide tetrafluorides (NaLnF4) crystals, whose photoluminescence efficiency is comparable to LiYF4. Therefore, NaLaF4 crystals may be important in the development of diode pumped up-conversion solid-state lasers. The number and behavior of the observed optical phonon modes were analyzed in terms of group theory predictions for the group symmetry found. A few anomalies in the phonon characteristics are discussed in terms of cationic disorder in the crystal lattice.
