Mixed Mode Filters (Short Papers) (1974)

Mixed mode bandpass filters are described which utilize alternating TE/sub 011//spl deg/ and TE/sub n11//spl deg/ circular waveguide cavity modes. This novel filter configuration exhibits both excellent unloaded Q and spurious mode response characteristics. The use of mixed resonant modes makes possible the design of microwave filters for both in-line side wall connected cylindrical resonators as well as folded planar filter configurations, whereby cross-coupling between selected resonators can be realized.
REGION-BASED TONE MAPPING FOR EFFICIENT HIGH DYNAMIC RANGE VIDEO CODING (2016)

In this paper, we address the problem of efficient High Dynamic Range (HDR) video coding. For this purpose, we introduce a new representation which segments the HDR image into low-range and high-range regions which are independently tone mapped. This representation allows preserving more information, leading to a higher visual quality of the reconstructed HDR image.
The inactivation of glyphosate by various soils and metal salts* (1978)

Summary: Résumé: Zusammenfassung A root bioassay was used to determine the effect of various soils, and the chloride salts of Fe +++ , Fe ++ , Al +++ , Ca ++ , K + , and Na + on the activity of glyphosate (N‐(phosphonomethyl)glycine]. Mineral soils significantly reduced the inhibitory effects of glyphosate on root growth. One muck soil inactivated glyphosate, but another muck soil and bentonite clay had little effect. Soils with the greatest inactivation capabilities had high concentrations of weak‐acid‐extractable iron. Glyphosate inactivation showed no correlation between cation exchange capacity and organic matter of the muck soils. FeCl 3 , FeCl 2 and AlCl 3 , significantly reduced the activity of glyphosate, and, when allowed to stand in solution, combinations of FeCl 3 and glyphosate formed a precipitate. CaCl 2 , KCl and NaCl did not inactivate glyphosate. Inactivation du glyphosate par divers sols et sels métalliques Un test biologique sur racines a été utilisé pour déterminer l'action de divers sols et de sels chlorés de Fe +++ , Fe ++ , Al ++ , Ca ++ , K + , et Na + sur I'activité du glyphosate N‐(phosphono‐méthyl) glycine. Les sols minéraux ont réduit significativement les effets inhibiteurs du glyphosate sur la croissance des racines. Un sol organique a inactivé le glyphosate, mais un autre sol organique, ainsi que la bentonite. n'ont eu que peu d'effet. Les sols qui ont présenté les plus grandes possibilités d'inactivation renfermaient des concentrations élevées dc fcr extractible par des acides faibles. II n'a pas été observé, en ce qui concerne l'inactivation du glyphosate, de corrélation entre la capaeité d'échange des cations et la teneure matiére organique des sols organiques. FeCl 3 , FeCl 2 , et AlCl 3 ont significativement réduit l'activité du glyphosate et, lorsqu'ils ont été mis en présenceen solution, la combinaison de FeCl 3 et du glyphosate a provoqué la formation d'un précipité, CaCl 2 , KCl et NaCl n'ont pas inactivé le glyphosate. Die Inaktivierung von Glyphosat durch verschiedene Böden und Metallsalze Die Wirkung verschiedener Bödden und der Chloride von Fe +++ , Fe ++ , Al +++ , Ca ++ , K + und Na + auf die Aktivität von Glyphosat N‐(Phosphonomethyl)glycin wurde mit einem Wurzel‐Biotest festgestellt. Mineralische Böden verringerten signifkant den Hemmeffekt von Glyphosat auf das Wurzelwachstum. Durch einen der organischen Böden wurde Glyphoat inaktiviert, ein anderer und das Tonmineral Bentonit, wirkten jedoch nur wenig inaktivierend. Böden mit der stärksten Inaktivierungsfähigkeit besassen hohe Konzentrationen an mit schwacher Säure extrahierbarem Eisen. Die Inaktivierung von Glyphosat war nicht mil der Kationen‐Austauschkapazität und dem Gehalt der Böden an organischer Substanz korreliert Durch FeCl 3 , FeCl 2 und AlCl 3 wurde die Aktivitat von Glyphosat signifikant verringert. Wenn FeCl 3 und Glyphosat in Lösung zusammengebracht wurden, bildete sich beim Stehenlassen dieser Kombination ein Niederschlag. CaCl 2 , KCl und NaCl wirkten auf Glyphosat nicht inaktivierend.
Goal-oriented Object Importance Estimation in On-road Driving Videos (2019)

We formulate a new problem as Object Importance Estimation (OIE) in on-road driving videos, where the road users are considered as important objects if they have influence on the control decision of the ego-vehicle's driver. The importance of a road user depends on both its visual dynamics, e.g., appearance, motion and location, in the driving scene and the driving goal, \emph{e.g}., the planned path, of the ego vehicle. We propose a novel framework that incorporates both visual model and goal representation to conduct OIE. To evaluate our framework, we collect an on-road driving dataset at traffic intersections in the real world and conduct human-labeled annotation of the important objects. Experimental results show that our goal-oriented method outperforms baselines and has much more improvement on the left-turn and right-turn scenarios. Furthermore, we explore the possibility of using object importance for driving control prediction and demonstrate that binary brake prediction can be improved with the information of object importance.
Market for hot gas filtration (1998)

Filtration competes with electrostatic precipitation as a method of removing particles from hot gas. Since the first cement kiln precipitator was installed 70 years ago to protect orange groves in California, precipitators have been the equipment of choice for hot gas purification applications. However the development of high temperature fabrics and rigid candles has allowed this alternative technology to make inroads in the industrial boiler, waste incineration, and utility boiler segments as this article reports.
Postprandial Glucose Regulation and Diabetic Complications (2004)

Atherosclerotic disease accounts for much of the increased mortality and morbidity associated with type 2 diabetes. Epidemiological studies support the potential of improved glycemic control to reduce cardiovascular complications. An association between glycosylated hemoglobin (HbA(1c)) level and the risk for cardiovascular complications has frequently been reported. Most epidemiological data implicate postprandial hyperglycemia in the development of cardiovascular disease, whereas the link between fasting glycemia and diabetic complications is inconclusive. Moreover, in many studies, postprandial glycemia is a better predictor of cardiovascular risk than HbA(1c) level. Postprandial glucose may have a direct toxic effect on the vascular endothelium, mediated by oxidative stress that is independent of other cardiovascular risk factors such as hyperlipidemia. Postprandial hyperglycemia also may exert its effects through its substantial contribution to total glycemic exposure. The present review examines the hypothesis that controlling postprandial glucose level is an important strategy in the prevention of cardiovascular complications associated with diabetes.
<i>In vivo</i> modulation of foreign body response on polyurethane by surface entrapment technique (2010)

Implanted polymeric materials, such as medical devices, provoke the body to initiate an inflammatory reaction, known as the foreign body response (FBR), which causes several complications. In this study, polyurethane (Tecoflex®, PU) surface modified with the nonionic surfactant Tween80® (PU/T80) and the cell adhesive PLL-RGD peptide (PU/PLL-RGD) by a previously described entrapment technique were implanted in the peritoneal cavity of Wistar rats for 30 days. Implants were retrieved and examined for tissue reactivity and cellular adherence by various microscopic and analytical techniques. Surface-induced inflammatory response was assessed by real-time PCR based quantification of proinflammatory cytokine transcripts, namely, TNF-α and IL-1β, normalized to housekeeping gene GAPDH. Cellular adherence and their distribution profile were assessed by microscopic examination of H&E stained implant sections. It was observed that PU/PLL-RGD followed by the bare PU surface exhibited severe inflammatory and fibrotic response with an average mean thickness of 19 and 12 μm, respectively, in 30 days. In contrast, PU/T80 surface showed only a cellular monolayer of 2-3 μm in thickness, with a mild inflammatory response and no fibrotic encapsulation. The PU/PLL-RGD peptide-modified substrate promoted an enhanced rate of macrophage cell fusion to form foreign body giant cell (FBGCs), whereas FBGCs were rarely observed on Tween80®-modified substrate. The expression levels of proinflammatory cytokines (TNF-α and IL-1β) were upregulated on PU/PLL-RGD surface followed by bare PU, whereas the cytokine expressions were significantly suppressed on PU/T80 surface. Thus, our study highlights modulation of foreign body response on polyurethane surfaces through surface entrapment technique in the form of differential responses observed on PLL-RGD and Tween80® modified surfaces with the former effective in triggering tissue cell adhesion thereby fibrous encapsulation, while the later being mostly resistant to this phenomenon.
Special Article: Chronic granulomatous disease in the United Kingdom and Ireland: a comprehensive national patient-based registry (2008)

There are no epidemiological studies from the British Isles of chronic granulomatous disease, characterized by recurrent, life-threatening bacterial and fungal infections and inflammatory sequelae. Patients were enrolled in a national registry and medical records were analysed. Of 94 subjects, 69 had X-linked disease, 16 had autosomal recessive disease and nine were unknown. Prevalence was 7.5/million for 1990-99 and 8.5/million for 1980-89. Suppurative adenitis, abscesses and pneumonia presented commonly. Twenty-three of 30 patients who underwent high resolution computerized tomography had chronic respiratory disease. Inflammatory sequelae included bowel stricture and urogenital tract granulomata. Growth failure was common; 75% of those measured were below the population mean. All patients received prophylactic antibiotics and 93% anti-fungal prophylaxis. Interferon gamma was used to treat infection, but rarely as prophylaxis. Despite prophylaxis, estimated survival was 88% at 10 years but 55% at age 30 years. Morbidity remains significant, severe infectious complications common. Curative treatments including stem cell transplantation should be considered for patients with frequent or serious complications.
Determination of channel temperature in AlGaN/GaN HEMTs grown on sapphire and silicon substrates using DC characterization method (2002)

Self-heating effects and temperature rise in AlGaN/GaN HEMTs grown on silicon and sapphire substrates are studied, exploiting transistor DC characterization methods. A negative differential output resistance is observed for high dissipated power levels. An analytical formula for a source-drain current drop as a function of parasitic source resistance and threshold voltage changes is proposed to explain this behavior. The transistor source resistance and threshold voltage is determined experimentally at different elevated temperatures to construct channel temperature versus dissipated power transfer characteristic. It is found that the HEMT channel temperature increases rapidly with dissipated power and at 6 W/mm reaches values of /spl sim/320/spl deg/C for sapphire and /spl sim/95/spl deg/C for silicon substrate, respectively.
Bicistronic DNA Vaccines Simultaneously Encoding HIV, HSV and HPV Antigens Promote CD8+ T Cell Responses and Protective Immunity (2013)

Millions of people worldwide are currently infected with human papillomavirus (HPV), herpes simplex virus (HSV) or human immunodeficiency virus (HIV). For this enormous contingent of people, the search for preventive and therapeutic immunological approaches represents a hope for the eradication of latent infection and/or virus-associated cancer. To date, attempts to develop vaccines against these viruses have been mainly based on a monovalent concept, in which one or more antigens of a virus are incorporated into a vaccine formulation. In the present report, we designed and tested an immunization strategy based on DNA vaccines that simultaneously encode antigens for HIV, HSV and HPV. With this purpose in mind, we tested two bicistronic DNA vaccines (pIRES I and pIRES II) that encode the HPV-16 oncoprotein E7 and the HIV protein p24 both genetically fused to the HSV-1 gD envelope protein. Mice i.m. immunized with the DNA vaccines mounted antigen-specific CD8⁺ T cell responses, including in vivo cytotoxic responses, against the three antigens. Under experimental conditions, the vaccines conferred protective immunity against challenges with a vaccinia virus expressing the HIV-derived protein Gag, an HSV-1 virus strain and implantation of tumor cells expressing the HPV-16 oncoproteins. Altogether, our results show that the concept of a trivalent HIV, HSV, and HPV vaccine capable to induce CD8⁺ T cell-dependent responses is feasible and may aid in the development of preventive and/or therapeutic approaches for the control of diseases associated with these viruses.
[Metabolic syndrome and nephrolithiasis]. (2011)

Recent epidemiological studies revealed an association of obesity, diabetes mellitus, hypertension and metabolic syndrome (MetS) with kidney stone disease. We examined how these disorders cause kidney stones. A clinical study on 467 patients with nephrolithiasis at our institution revealed that clustering of MetS traits increased the risk of uric acid stone formation by decreasing urinary pH. A subsequent study analyzing detailed data from 30,448 patients enrolled in the 6th Nationwide Survey on Urolithiasis in Japan showed that clustering of MetS traits were associated with an increased severity of the kidney stone disease and elevated urinary excretion of calcium, uric acid and oxalate. Finally, the OLETF rats, an animal model of MetS, showed lower urinary pH, decreased citrate excretion, and increased uric acid and calcium excretion. In addition, the administration of pioglitazone, an agent that improves insulin resistance, significantly increased the urinary pH. These results indicate that MetS causes changes in urinary constituents, leading to an increased risk of both uric acid and calcium oxalate stone formation. We suggest that kidney stone disease should be considered as a component of MetS and that the improvement in insulin resistance by means of diet and lifestyle changes and medical therapy might help to prevent this disorder.
Heat-Processed Photoresist for Holographic Data Storage Applications (1973)

The experimental evaluation of a new heat-processed photoresist is reported with reference to holographic data storage applications. Two attractive features of the photoresist are (1) holographic reconstruction parameters comparable to the best photographic emulsions and (2) orthochromatic exposure sensitivity optimized for the 488-nm line of an argon laser. The preparation, use, and general properties of the photoresist are discussed, and relevant experimental data for important holographic parameters such as diffraction efficiency and storage density are presented.
On the existence theorems of Kantorovich, Miranda and Borsuk. (2004)

Abstract. The theorems of Kantorovich, Miranda and Borsuk all give conditions on the existence of a zero of a nonlinear mapping. In this paper we are concerned with relations between these theorems in terms of generality in the case that the mapping is finite-dimensional. To this purpose we formulate a generalization of Miranda’s theorem, holding for arbitrary norms instead of just the-norm. As our main results we then prove that the Kantorovich theorem reduces to a special case of this generalized Miranda theorem as well as to a special case of Borsuk’s theorem. Moreover, it turns out that, essentially, the Miranda theorems are themselves special cases of Borsuk’s theorem.
Fast Handover Mechanism for Efficient Mobility Support in ZigBee Networks (2006)

This paper proposes a method to endow the mobility to the Zigbee protocol which is a short distance wireless communication technology among the standards of wireless sensor networks. The Zigbee has a low price, long life battery, simple structure and connectivity. So it is a suitable standard for the short distance wireless communication of . As the Zigbee does not support the mobility, additional factors should be studied to deal adeptly with the diverse change in the real field. By solving the problem that the previous connection and binding table of the Zigbee end device should be reset due to the Zigbee end device address variation when the Zigbee end device moves from the present router to another router, this paper presents the method to communicate without data loss or disconnection.
A new, simple and exact result for calculating the probability of error for two-dimensional signal constellations (2002)

The author presents a simple integral expression for calculating the exact probability of a symbol error for an arbitrary array of signal points. The integrand contains only elementary functions and the range of integration is finite. The approach is introduced by applying it to M-ary phase shift keying (MPSK). The special case of M=2 gives novel and possibly useful expressions for calculating the Gaussian tail probability function and the related complementary error function. The approach is outlined for polygonal decision regions, and results are given for 16-point signal constellations. A method of obtaining, not exact, but even simpler and highly accurate expressions for symbol error probability when the latter is less than a few hundredths is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Network Modeling Identifies Molecular Functions Targeted by miR-204 to Suppress Head and Neck Tumor Metastasis (2010)

Due to the large number of putative microRNA gene targets predicted by sequence-alignment databases and the relative low accuracy of such predictions which are conducted independently of biological context by design, systematic experimental identification and validation of every functional microRNA target is currently challenging. Consequently, biological studies have yet to identify, on a genome scale, key regulatory networks perturbed by altered microRNA functions in the context of cancer. In this report, we demonstrate for the first time how phenotypic knowledge of inheritable cancer traits and of risk factor loci can be utilized jointly with gene expression analysis to efficiently prioritize deregulated microRNAs for biological characterization. Using this approach we characterize miR-204 as a tumor suppressor microRNA and uncover previously unknown connections between microRNA regulation, network topology, and expression dynamics. Specifically, we validate 18 gene targets of miR-204 that show elevated mRNA expression and are enriched in biological processes associated with tumor progression in squamous cell carcinoma of the head and neck (HNSCC). We further demonstrate the enrichment of bottleneckness, a key molecular network topology, among miR-204 gene targets. Restoration of miR-204 function in HNSCC cell lines inhibits the expression of its functionally related gene targets, leads to the reduced adhesion, migration and invasion in vitro and attenuates experimental lung metastasis in vivo. As importantly, our investigation also provides experimental evidence linking the function of microRNAs that are located in the cancer-associated genomic regions (CAGRs) to the observed predisposition to human cancers. Specifically, we show miR-204 may serve as a tumor suppressor gene at the 9q21.1-22.3 CAGR locus, a well established risk factor locus in head and neck cancers for which tumor suppressor genes have not been identified. This new strategy that integrates expression profiling, genetics and novel computational biology approaches provides for improved efficiency in characterization and modeling of microRNA functions in cancer as compared to the state of art and is applicable to the investigation of microRNA functions in other biological processes and diseases.

Airbnb research: an analysis in tourism and hospitality journals (2020)

Purpose The purpose of this study is to examine Airbnb research using bibliometric methods. Using research performance analysis, this study highlights and provides an updated overview of Airbnb research by revealing patterns in journals, papers and most influential authors and countries. Furthermore, it graphically illustrates how research themes have evolved by mapping a co-word analysis and points out potential trends for future research. Design/methodology/approach The methodological design for this study involves three phases: the document source selection, the definition of the variables to be analyzed and the bibliometric analysis. A statistical multivariate analysis of all the documents’ characteristics was performed with R software. Furthermore, natural language processing techniques were used to analyze all the abstracts and keywords specified in the 129 selected documents. Findings Results show the genesis and evolution of publications on Airbnb research, scatter of journals and journals’ characteristics, author and productivity characteristics, geographical distribution of the research and content analysis using keywords. Research limitations/implications Despite Airbnb having a history of 10 years, research publications only started in 2015. Therefore, the bibliometric study includes papers from 2015 to 2019. One of the main limitations is that papers were selected in October of 2019, before the year was over. However, the latest academic publications (in press and earlycite) were included in the analysis. Originality/value This study analyzed bibliometric set of laws (Price’s, Lotka’s and Bradford’s) to better understand the patterns of the most relevant scientific production regarding Airbnb in tourism and hospitality journals. Using natural language processing techniques, this study analyzes all the abstracts and keywords specified in the selected documents. Results show the evolution of research topics in four periods: 2015-2016, 2017, 2018 and 2019.
