Xlet-based, IESG(Integrated Electronic Service Guide) in ATSC-ACAP (2006)

This paper describes the outline of Integrated Electronic Service Guide(IESG) system and service. IESG service is designed to compose Electronic Program Guide(EPG), interactive TV service information such as TV portal service and genre information in ATSCACAP( Advanced Television System Committee -Advanced Common Application Platform). ACAP is a Java based data broadcasting standard for interactive TV service through digital TV set-top boxes. To make it possible, broadcasters have to transmit program scheduling information and interactive TV service information. However, terrestrial broadcasters adopting ATSC standard transmit only their own program guides, not those of other broadcasters because of lack of bandwidth and other business issues. This paper suggests an effective way of IESG service implementation in which, based on ACAP, PSIP standard is used to display a broadcaster's own channel program guide, and Return Channel is used for the program guide , genre information and interactive TV service of other broadcasters.
GaN MMIC broadband Doherty power amplifier (2013)

A quarter-wavelength transformer, phase compensation network, offset line are the bandwidth limiting factors of Doherty PAs. In this paper, we expand the bandwidth of the Doherty PA by employing a new structure. The conventional phase compensation network is merged into an input matching circuit and the offset line is resonated-out by an inductor. The quarter wavelength transformer has a low-Q characteristic compared to that of conventional one. With the proposed topology, a broadband Doherty PA is implemented using TriQuint 3MI 0.25μm GaN-HEMT MMIC process. Across 2.1-2.7 GHz, the implemented PA delivered a DE of over 40.5%, a gain of over 11.8 dB and ACPR of below -45dBc at an average power of over 33.2 dBm for LTE signal with a 6.5 dB peak-to-average power ratio. This fully integrated circuit has a chip-size of 3.5mm by 1.9mm.
PSoC-Stat: A single chip open source potentiostat based on a Programmable System on a Chip (2018)

In this paper we demonstrate a potentiostat built with a single commercially available integrated circuit (IC) that does not require any external electronic components to perform electrochemical experiments. This is done using the capabilities of the Programmable System on a Chip (PSoC®) by Cypress Semiconductor, which integrates all of the necessary electrical components. This is in contrast to other recent papers that have developed potentiostats but require technical skills or specialized equipment to produce. This eliminates the process of having to make a printed circuit board and soldering on electronic components. To control the device, a graphical user interface (GUI) was developed in the python programming language. Python is open source, with a style that makes it easy to read and write programs, making it an ideal choice for open source projects. As the developed device is open source and based on a PSoC, modification to implement other electrochemical techniques is straightforward and only requires modest programming skills, but no expensive equipment or difficult techniques. The potentiostat developed here adds to the growing amount of open source laboratory equipment. To demonstrate the PSoC potentiostat in a wide range of applications, we performed cyclic voltammetry (to measure vitamin C concentration in orange juice), amperometry (to measure glucose with a glucose strip), and stripping voltammetry experiments (to measure lead in water). The device was able to perform all experiments and could accurately measure Vitamin C, glucose, and lead.
Mechanical and electrical behaviour of an electric vehicles drive train due to the choice of the control-system (2011)

A future-orientated strategy for the use of energy within passenger cars is electrical energy. Due to this developpment there is a need of considering the conditioning of electrical energy to be used for electrical machines under conditions of an electric vehicle. Comparing a fixed step-size control-system with a space-vector based hysteresis-control (bang-bang-control), the high frequent influence to the whole power train is evaluated with a view to the electrical and mechanical subsystems. Furthermore the travelling comfort is a target of the study. As electrical drives for electric vehicles need to have a wide speed range and likewise be robust the chosen control processes are applied to a permanent magnetic synchronous machine (PMSM) [1]. This offers the opportunity of a gearless drive which by the way offers a big advantage in comparison to combustion engines. To connect the energy source to the PMSM there is an inverter which builds up three-phases and likewise a rectifier in the opposed direction with a set of IGBTs and integrated antiparallel diodes. The command signal is set by a torque demand as known in a traditional car with the help of an acceleration pedal. [2] [3] the mechanical part of the drive train is build by a double oscillator as it is close to reality.
Adsorption of human serum albumin to amberlite XAD‐7 resin (1979)

Abstract In the present study the conditions leading to tight binding of human serum albumin to the Amberlite XAD‐7 resin without the use of chemical coupling agents have been defined. Optimal binding (10.97 mm/kg dry XAD‐7) was achieved at p H 5.0 and adsorption conformed to a Langmuir isotherm. Theoretical analysis of the data suggest adsorption of a monolayer of albumin which is suported by the absence of visual surface coating on scanning electron micrographs. Binding of human serum albumin was reduced when two chemical coupling agents, glutaraldehyde and carbodiimide were included in the human serum albumin solution, the elution of adsorbed HSA from the resins under severe flow conditions was reduced, and the amount eluted was minimal in all instances.
Silicone Rubber Supporting IT Application of Selective Self-adhesive LSR for Keypads of Mobile Phone (2006)

Selective self-adhesive LSR (Liquid Silicone Rubber) offers good adhesion to thermoplastics, but does not adhere to the metal surfaces of molds, so it enables us to operate insert molding without any primers or to make a co-injection molding. This selective self-adhesive mechanism can be explained as follows: The adhesion promoter containing of functional groups X and Y in a molecule is insoluble in silicone polymer. The group X has similar structure to thermoplastic polymer while the group Y can be cross-linked with LSR. When the adhesion promoters added to the LSR migrate to the interface, group X tends to adjust themselves to make an interaction with thermoplastics, which results in strong bonding between LSR and thermoplastics. On the other hands there is a weak interaction between the adhesion promoters and metallic mold owing to the low reactivities of X and Y with metal surfaces.The selective self-adhesive LSR is mainly applied for keypads of mobile phone, for example, 1) plastic keypads of frame type, and 2) film keypads of filed with silicone rubber. For the frame type, this LSR is usually used through the insert molding to polycarbonate parts, and film keypads are made of polyurethane films with this LSR by the compression molding after dispensation. In both cases, there is a good reason to choose this selective self-adhesive LSR, not only skipping priming process but also reducing labor-costs by eliminating time-consuming handling process.
Seasonal Relevance in E-Commerce Search (2021)

Seasonality is an important dimension for relevance in e-commerce search. For example, a query jacket has a different set of relevant documents in winter than summer. For an optimal user experience, the e-commerce search engines should incorporate seasonality in product search. In this paper, we formally introduce the concept of seasonal relevance, define it and quantify using data from a major e-commerce store. In our analyses, we find 39% queries are highly seasonally relevant to the time of search and would benefit from handling seasonality in ranking. We propose LogSR and VelSR features to capture product seasonality using state-of-the-art neural models based on self-attention. Comprehensive offline and online experiments over large datasets show the efficacy of our methods to model seasonal relevance. The online A/B test on 784 MM queries shows the treatment with seasonal relevance features results in 2.20% higher purchases and better customer experience overall.
FULL PAPER (2015)

Caring' is a fundamental aspect to achieve successful education. A teacher who believes on students' potentials applies a student-centered learning process and stimulates them to be more active in learning process to show his/her "care". To overcome the problem of 'caring' for the elementary school teachers, Behavior Modeling Training is an effective approach to improve the 'caring' of the teachers because this model has clear guidance in changing the behavior. Whether there is any influence from Behavior Modeling Training to the 'caring' between the primary school teacher with and without the BMT approach is becoming the concentration of the problems to be answered in this study. This research is using the true experiment study with a pretest-posttest design in a control group. Subject of the research is two classes of 54 teachers in the fundamental grade (1-3) in the KKG 06 group in Sidoarjo. The sample is randomly selected while the collected data is statistically processed by using ANOVA analysis technique with the SPSS 20.0 program for windows. Based on the data analysis, the research found: (1) the application of BMT for primary teachers affect the 'caring' of the teachers, (2) the effectiveness of the application of BMT can be seen from the result of ANOVA statistical tests of control and experimental groups. The research simultaneously found the significant differences of the 'caring' between the teachers who were trained and not trained with BMT.
Structure and Mechanism of an Aspartimide‐Dependent Peptide Ligase in Human Legumain (2015)

Peptide ligases expand the repertoire of genetically encoded protein architectures by synthesizing new peptide bonds, energetically driven by ATP or NTPs. Here, we report the discovery of a genuine ligase activity in human legumain (AEP) which has important roles in immunity and tumor progression that were believed to be due to its established cysteine protease activity. Defying dogma, the ligase reaction is independent of the catalytic cysteine but exploits an endogenous energy reservoir that results from the conversion of a conserved aspartate to a metastable aspartimide. Legumain's dual protease-ligase activities are pH- and thus localization controlled, dominating at acidic and neutral pH, respectively. Their relevance includes reversible on-off switching of cystatin inhibitors and enzyme (in)activation, and may affect the generation of three-dimensional MHC epitopes. The aspartate-aspartimide (succinimide) pair represents a new paradigm of coupling endergonic reactions in ATP-scarce environments.
Distinct molecular mechanisms of acquired resistance to temozolomide in glioblastoma cells (2012)

Temozolomide (TMZ) is an alkylating chemotherapeutic agent that prolongs the survival of patients with glioblastoma. Clinical benefit is more prominent in patients with methylation of the O(6) -methyl-guanine DNA methyltransferase (MGMT) promoter. However, all patients eventually suffer from tumor progression because their tumors become resistant to TMZ. Here, we modeled acquired TMZ resistance in glioma cells in vitro to identify underlying molecular mechanisms. To this end, the glioma cell lines LNT-229, LN-308, and LN-18 were exposed repetitively to increasing concentrations of TMZ to induce a stable resistant phenotype (R) defined by clonogenic survival assays. The molecular mechanisms mediating acquired resistance were assessed by immunoblot, PCR, and flow cytometry. Rescue experiments were performed with siRNA-mediated candidate gene silencing. We found in LN-18 cells constitutively expressing MGMT a strong up-regulation of MGMT levels in TMZ-resistant cells. TMZ resistance in the MGMT-negative cell lines LNT-229 and LN-308 was not associated with de novo expression of MGMT. Instead, we found a down-regulation of several DNA mismatch-repair proteins in resistant LNT-229 cells. A TMZ-resistant phenotype was also achieved by silencing selected DNA mismatch repair proteins in parental LNT-229 cells. No obvious mechanism of resistance was identified in the third cell line, LN-308, except for reduced methylation of LINE-1 repetitive elements. In conclusion, we demonstrate that different molecular mechanisms may contribute to the development of acquired TMZ resistance in glioma cells, indicating the need to develop distinct strategies to overcome resistance.
Diastereoselective Dealkoxycarbonylation of Sulfur-Substituted Dialkyl Cyclopropane-1,1-dicarboxylates (1990)

In the dealkoxycarbonylation of dimethyl 2,2-dimethylcyclo- propane-1,1-dicarboxylate, 3-alkylthio or 3-arylthio substituents induce moderate diastereoselection. The analogous dealkoxycarbonylation of 3-alkylsulfonyl- or 3-arylsulfonyl-substituted cyclopropanes leads to an E diastereoselectivity of 100%.

An RF circuit model for carbon nanotubes (2003)

We develop an rf circuit model for single walled carbon nanotubes for both dc and capacitively contacted geometries. By modeling the nanotube as a nano-transmission line with distributed kinetic and magnetic inductance as well as distributed quantum and electrostatic capacitance, we calculate the complex, frequency dependent impedance for a variety of measurement geometries. Exciting voltage waves on the nano-transmission line is equivalent to directly exciting the yet-to-be observed one dimensional plasmons, the low energy excitation of a Luttinger liquid.
Vehicle Mobility and Communication Channel Models for Realistic and Efficient Highway VANET Simulation (2014)

Developing real-time safety and nonsafety applications for vehicular ad hoc networks (VANETs) requires understanding of the dynamics of the network topology characteristics since these dynamics determine both the performance of routing protocols and the feasibility of an application over VANETs. Using various key metrics of interest, including node degree, neighbor distribution, number of clusters, and link duration, we provide a realistic analysis of the VANET topology characteristics over time and space for a highway scenario. In this analysis, we integrate real-world road topology and real-time data extracted from the freeway Performance Measurement System (PeMS) database into a microscopic mobility model to generate realistic traffic flows along the highway. Moreover, we use a more realistic, recently proposed, obstacle-based channel model and compare the performance of this sophisticated model to the most commonly used and more simplistic channel models, including unit disk and lognormal shadowing models. Our investigation on the key metrics reveals that both lognormal and unit disk models fail to provide realistic VANET topology characteristics. We therefore propose a matching mechanism to tune the parameters of the lognormal model according to the vehicle density and a correlation model to take into account the evolution of the link characteristics over time. The proposed method has been demonstrated to provide a good match with the computationally expensive and difficult-to-implement obstacle-based model. The parameters of the proposed model have been validated to depend only on the vehicle traffic density based on the real data of four different highways in California.

Large scale integration for display screens (1976)

Solid state devices and circuits have now achieved a dominant position in most areas of electronics in which vacuum tubes formerly held sway. They have also opened up new areas of electronic applications ( e.g. computers, calculators) not accessible to the vacuum tube. In this triumphant march of solid state technology there is, however, one vacuum tube fortress that has held off all challengers, and seems as impregnable as ever --the TV tube!
Human Tumor Antigens Tn and Sialyl Tn Arise from Mutations in <i>Cosmc</i> (2008)

Neoplastic lesions typically express specific carbohydrate antigens on glycolipids, mucins, and other glycoproteins. Such antigens are often under epigenetic control and are subject to reversion and loss upon therapeutic selective pressure. We report here that two of the most common tumor-associated carbohydrate antigens, Tn and sialyl Tn (STn), result from somatic mutations in the gene Cosmc that encodes a molecular chaperone required for formation of the active T-synthase. Diverse neoplastic lesions, including colon cancer and melanoma-derived cells lines, expressed both Tn and STn antigen due to loss-of-function mutations in Cosmc. In addition, two human cervical cancer specimens that showed expression of the Tn/STn antigens were also found to have mutations in Cosmc and loss of heterozygosity for the cross-linked Cosmc locus. This is the first example of somatic mutations in multiple types of cancers that cause global alterations in cell surface carbohydrate antigen expression.
WITHDRAWAL FROM FREE-CHOICE ETHANOL CONSUMPTION RESULTS IN INCREASED PACKING DENSITY OF GLUTAMINE SYNTHETASE-IMMUNOREACTIVE ASTROCYTES IN THE PRELIMBIC CORTEX OF ALCOHOL-PREFERRING RATS (2006)

Excess activation of glutamatergic neurotransmission in the cerebral cortex following ethanol withdrawal is considered to contribute to significant behavioural disturbances, and to alcohol craving. Astrocytes may play a role in these manifestations because astrocytes are essential in the regulation of released glutamate and its conversion to glutamine through the enzyme glutamine synthetase (GS). However, it is unclear if withdrawal from free-choice ethanol drinking causes changes in the numbers of astrocytes expressing GS or the cytoskeletal protein of astrocytes glial fibrillary acidic protein (GFAP). Alcohol-preferring (P) rats exposed to free-choice ethanol drinking were either maintained without forced interruption of ethanol drinking, subjected to a 3-day withdrawal period at the end of 2 months, or subjected to three 3-day withdrawal periods along 6 months. At 2 months, P rats were also compared with alcohol-naïve alcohol non-preferring rats (NP) rats. Packing density of GS and GFAP-immunoreactive (IR) astrocytes was measured in sections from the prelimbic cortex (PLC) using the optical disector probe. An alcohol deprivation effect was observed in P rats with withdrawals during a 6-month ethanol drinking period. Ethanol withdrawal significantly increased the packing density of GS- and GFAP-IR astrocytes in the PLC of P rats as compared with P rats with continuous access to ethanol. In addition, there was a positive correlation between the pre-withdrawal ethanol consumption and the packing density of GS-IR astrocytes. The present results suggest the involvement of astrocytes in the regulation of the glutamatergic activation associated with withdrawal from free-choice ethanol consumption and point to differential adaptations of GS and GFAP to prolonged alcohol drinking in the PLC of P rats.
Partial purification of leaf lectin from Manihot esculenta and screening its fungicidal activity (2010)

Lectins have various biotechnological applications including their use in agriculture as antimicrobials and pesticides. Lectin from manioc leaf powder has been extracted, partially purified and evaluated in terms of its haemagglutination activity and fungicidal properties against Fusarium oxysporum. Ground, dried and the entire leaves of Manihot esculenta (Cacao cultivar) were extracted with distilled water and the protein extract was concentrated by precipitation in 80% saturated ammonium sulphate solution. The concentrated protein solution was partially purified on a Sepharose column and the unbound protein fraction was submitted to native and denaturing polyacrylamide gel electrophoresis. Lectin from manioc leaf powder exhibited a haemagglutination (HU) activity of 0.5 HU/100 μl and was stable over a wide temperatures range (up to 70°C). Four protein bands (of 13, 58, 61, 64 kDa) were identified in the unbound protein fraction obtained by column chromatography, and the presence of a lectin was demonstrated by the determination of an HA value of 0.5 HU/100 μl. The concentrated protein solution was not, however, active against F. oxysporum at concentrations up to 100 μg/ml.
