Group communication system based on MAC-over-IP (2003)

We have researched a regional personal computer (PC) communication network system to provide group communication services to regional community members cost-effectively. Its LAN-like environment enables pre-registered users to communicate with each other using a PC at any time. An STM-based system, which transfers Ethernet frames to/from users' PCs using HDLC (high-level data link control) protocol over ISDN access lines, has already been developed. Access systems that directly provide an Ethernet interface to users such as shared STM-PDS (synchronous transfer mode passive double star) and cable modem systems have recently been introduced. The communication services provided with the current access systems are basically Internet protocol (IP) services. Such access systems will be required to support protocol-free communication services as well as group communication services. We propose a new system architecture that is applicable to many kinds of access systems including shared STM-PDS and cable modem systems. It is based on MAC-over-IP where Ethernet frames from users' PC are encapsulated into IP packets in the edge device and filtered using the PC MAC (media access control) addresses in the center node. This paper describes the system architecture and its operations. The system can provide protocol-free services and guaranteed security to users. The processing load of the center node is reduced by cutting through the decapsulation of MAC-over-IP packets by controlling the ARP (address resolution protocol) packets. Performance evaluation results for a prototype system are presented.
Identification of Serum Biomarkers for Biliary Tract Cancers by a Proteomic Approach Based on Time-of-Flight Mass Spectrometry (2010)

Biliary tract cancers (BTCs) are lethal malignancies currently lacking satisfactory methods for early detection and accurate diagnosis. Surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) is a promising diagnostic tool for this disease. In this pilot study, sera samples from 50 BTCs and 30 cholelithiasis patients as well as 30 healthy subjects from a population-based case-control study were randomly grouped into training set (30 BTCs, 20 cholelithiasis and 20 controls), duplicate of training set, and blind set (20 BTCs, 10 cholelithiasis and 10 controls); all sets were analyzed on Immobilized Metal Affinity Capture ProteinChips via SELDI-TOF-MS. A decision tree classifier was built using the training set and applied to all test sets. The classification tree constructed with the 3,400, 4,502, 5,680, 7,598, and 11,242 mass-to-charge ratio (m/z) protein peaks had a sensitivity of 96.7% and a specificity of 85.0% when comparing BTCs with non-cancers. When applied to the duplicate set, sensitivity was 66.7% and specificity was 70.0%, while in the blind set, sensitivity was 95.0% and specificity was 75.0%. Positive predictive values of the training, duplicate, and blind sets were 82.9%, 62.5% and 79.2%, respectively. The agreement of the training and duplicate sets was 71.4% (Kappa = 0.43, u = 3.98, P < 0.01). The coefficient of variations based on 10 replicates of one sample for the five differential peaks were 15.8-68.8% for intensity and 0-0.05% for m/z. These pilot results suggest that serum protein profiling by SELDI-TOF-MS may be a promising approach for identifying BTCs but low assay reproducibility may limit its application in clinical practice.
Experimental demonstration of plasmon enhanced energy transfer rate in NaYF4:Yb3+,Er3+ upconversion nanoparticles (2016)

Energy transfer upconversion (ETU) is known to be the most efficient frequency upconversion mechanism. Surface plasmon can further enhance the upconversion process, opening doors to many applications. However, ETU is a complex process involving competing transitions between multiple energy levels and it has been difficult to precisely determine the enhancement mechanisms. In this paper, we report a systematic study on the dynamics of the ETU process in NaYF4:Yb(3+),Er(3+) nanoparticles deposited on plasmonic nanograting structure. From the transient near-infrared photoluminescence under various excitation power densities, we observed faster energy transfer rates under stronger excitation conditions until it reached saturation where the highest internal upconversion efficiency was achieved. The experimental data were analyzed using the complete set of rate equations. The internal upconversion efficiency was found to be 56% and 36%, respectively, with and without the plasmonic nanograting. We also analyzed the transient green emission and found that it is determined by the infrared transition rate. To our knowledge, this is the first report of experimentally measured internal upconversion efficiency in plasmon enhanced upconversion material. Our work decouples the internal upconversion efficiency from the overall upconverted luminescence efficiency, allowing more targeted engineering for efficiency improvement.
A review of real-time software engineering methodologies for developing a wall-climbing robot control firmware (2002)

Designing and developing software for autonomous robot control system is a challenging task. Issues related to real-time control, embedded system and artificial intelligence are involved in the software development process. This type of software must be developed with proper software methodology or well-defined development process in order to increase the productivity and quality of the software design and software products. This paper presents a review of two real-time software development methodologies and compares their suitability for developing real-time control software for a wall-climbing robot under development at Universiti Teknologi Malaysia (UTM).
MEASUREMENT OF THE FRICTION AND LUBRICITY PROPERTIES OF CONTACT LENSES (1995)

PEMFC Poisoning with H2S: Dependence on Operating Conditions (2007)

H2S is a well known poison for polymer electrolyte fuel cells. In this work we have found that the severity of H2S poisoning depends on H2S concentration, dosage, cell temperature and anode humidification. We found catalyst poisoning by H2S was cumulative and highly irreversible. After poisoning, further cell operation on neat hydrogen resulted only in modest performance recovery. Full recovery could usually be attained after repetitive cyclic voltammetry between 0 and 1.4 V. We discuss improvements of cell tolerance to H2S and performance recovery using other strategies, such as holding the cell at open circuit and anode air bleed during operation. We discuss the possible implications of H2S crossover on cathode performance.

CFTR and MDR: ABC Transporters with Homologous Structure but Divergent Function (2003)

While a gene family by definition will have homologies in sequence, the “functional genomics” or characterization of the functionality of siblings can reveal significant differences. One gene family that shares an ATPbinding cassette (ABC) sequence motif is comprised of members named “ABC Transporters.” Until 1989, the members of this family were primarily ATPases that pumped compounds out of cells and many were linked to multidrug resistance (MDR). Hence, at that time the function of the members of the ABC gene family appeared equally homologous to their structure. Since then the discovery of new members, like the cystic fibrosis transmembrane conductance regulator (CFTR) Cl- channel and the sulfonylurea receptor (SUR), increased diversity and the homologous structure seemed to no longer link to homologous function. In this mini-review we will introduce two parallel investigations, separated by 10 years, where researchers re-examined the functionality of the human ABC transporters, CFTR and MDR, under the hypothesis that the structurally similar ABC transporters must have similarities in function.
Human interleukin-5 expressed in <i>Escherichia coli</i> has <i>N</i>-terminal modifications (1992)

Recombinant human interleukin-5 exists as four major isoforms all possessing N-terminal methionine. Peptide mapping and subsequent analysis by fast-atom-bombardment mass spectrometry (f.a.b.-m.s.) have shown that N-terminal modifications are the cause of the charge heterogeneity. In order of decreasing abundance, these are unmodified methionine, retention of N-terminal formyl group, oxidation of N-terminal methionine to sulphoxide and carbamoylation of the N-terminus. These results were confirmed by analysis of the reduced and alkylated intact protein by electrospray-ionization mass spectrometry. The implications of these findings for the production and characterization of recombinant proteins are briefly discussed.
Ariadne: An Eclipse-based system for tracking originality of source code (2007)

In this paper we introduce Ariadne, an Eclipse-based system for tracking the originality of source code in collaborative software development environments in which software reuse is a common practice. We describe its architecture within the Eclipse framework, the originality metadata of which it keeps track, and the history clue—the data structure used to implement the tracking mechanism. We also discuss the implementation of the Ariadne client, the main component of the system, and show how digital signatures are used to validate the integrity of the metadata-handling process. We demonstrate the functions of Ariadne in two typical scenarios: tracking of software bugs and generating originality claims for Certificate of Originality reports. Although our Eclipse-based prototype is designed to handle Java source code, our approach can be extended to other kinds of artifacts.
Clinical practice guidelines for the perioperative nutritional, metabolic, and nonsurgical support of the bariatric surgery patient—2013 update: Cosponsored by american association of clinical endocrinologists, The obesity society, and american society for metabolic & bariatric surgery* (2013)

The development of these updated guidelines was commissioned by the AACE, TOS, and ASMBS Board of Directors and adheres to the AACE 2010 protocol for standardized production of clinical practice guidelines (CPG). Each recommendation was re-evaluated and updated based on the evidence and subjective factors per protocol. Examples of expanded topics in this update include: the roles of sleeve gastrectomy, bariatric surgery in patients with type-2 diabetes, bariatric surgery for patients with mild obesity, copper deficiency, informed consent, and behavioral issues. There are 74 recommendations (of which 56 are revised and 2 are new) in this 2013 update, compared with 164 original recommendations in 2008. There are 403 citations, of which 33 (8.2%) are EL 1, 131 (32.5%) are EL 2, 170 (42.2%) are EL 3, and 69 (17.1%) are EL 4. There is a relatively high proportion (40.4%) of strong (EL 1 and 2) studies, compared with only 16.5% in the 2008 AACE-TOS-ASMBS CPG. These updated guidelines reflect recent additions to the evidence base. Bariatric surgery remains a safe and effective intervention for select patients with obesity. A team approach to perioperative care is mandatory with special attention to nutritional and metabolic issues.
Pharmacological evidence for the involvement of the endogenous opioid system in the response to local inflammation in the rat paw (1995)

We have investigated the role of the endogenous opioid system (EOS) on the inflammatory response induced by subplantar (s.p.) injection of saline (SS) and carrageenan (CA) in the hindpaw of the rat. The administration of intraperitoneal (i.p.) naloxone was used in order to unmask the effects of endogenous opiates released during peripheral inflammation. Three groups of rats received one of the following s.p. treatments: SS, CA, or no injection (NI). Pain pressure threshold (PPT), paw volume (edema) and local temperature were evaluated in baseline conditions and 3 h after treatment. In each group, the effects of i.p. vehicle, naloxone and (+)-naloxone (0.1 mg/kg) were also investigated. Both SS and CA induced a significant inflammatory response with hyperalgesia, edema and local hyperthermia. The i.p. administration of naloxone but not that of (+)-naloxone 15 min prior to testing, significantly increased edema in all groups of treatment (P < 0.05), without altering PPT or local temperature. Two-way ANOVA revealed that treatment and drugs, as well as their interaction, had a significant impact on edema which was related to the effects of CA and naloxone. Our findings illustrate the involvement of the EOS in the physiological response to local injury, regulating microvascular leakage in the inflamed tissues.
Sources of Resistance to Pepino mosaic virus (PepMV) in Tomato (2007)

The disease incited by Pepino mosaic virus (PepMV) is currently a serious problem for tomato ( Solanum lycopersicum L.) crops in several European countries. A collection of accessions from different Solanum species was screened to find sources of resistance to PepMV. All plants of S. lycopersicum , S. lycopersicum var. cerasiforme , S. pennellii Correll, S. cheesmaniae (L. Riley) Fosberg, S. habrochaites S. Knapp & D.M. Spooner, S. neorickii D.M. Spooner, G.J. Anderson & R.K. Jansen, S. pimpinellifolium L., S. basendopogon Bitter, S. canense Rydb., S. caripense Humb. & Bonpl. ex Dunal, and S. muricatum Aiton accessions showed a 100% systemic infection rate, high viral accumulation, and apparent symptoms. In some accessions of the species S. chilense (Dunal) Reiche and S. peruvianum L., a variable percentage of plants without systemic infection was observed. Although all plants of ECU-335 accession of S. ochranthum Dunal showed systemic infection by PepMV, the symptoms were mild and the levels of viral accumulation were low. PepMV was not detected in plants of AN-CA-214 accession of S. pseudocapsicum L. No symptoms were observed either on inoculated leaves or on growing leaves. The use of the latter two species is limited considering that they cannot be sexually crossed with cultivated tomato. As a result, S. chilense and S. peruvianum are the most promising species in the search for sources of resistance to PepMV.
Poliomyelitis Prevention in the United States: Updated Recommendations of the Advisory Committee on Immunization Practices (ACIP) (2000)

These recommendations of the Advisory Committee on Immunization Practices (ACIP) for poliomyelitis prevention replace those issued in 1997. As of January 1, 2000, ACIP recommends exclusive use of inactivated poliovirus vaccine (IPV) for routine childhood polio vaccination in the United States. All children should receive four doses of IPV at ages 2, 4, and 6-18 months and 4-6 years. Oral poliovirus vaccine (OPV) should be used only in certain circumstances, which are detailed in these recommendations. Since 1979, the only indigenous cases of polio reported in the United States have been associated with the use of the live OPV. Until recently, the benefits of OPV use (i.e., intestinal immunity, secondary spread) outweighed the risk for vaccine-associated paralytic poliomyelitis (VAPP) (i.e., one case among 2.4 million vaccine doses distributed). In 1997, to decrease the risk for VAPP but maintain the benefits of OPV, ACIP recommended replacing the all-OPV schedule with a sequential schedule of IPV followed by OPV. Since 1997, the global polio eradication initiative has progressed rapidly, and the likelihood of poliovirus importation into the United States has decreased substantially. In addition, the sequential schedule has been well accepted. No declines in childhood immunization coverage were observed, despite the need for additional injections. On the basis of these data, ACIP recommended on June 17, 1999, an all-IPV schedule for routine childhood polio vaccination in the United States to eliminate the risk for VAPP. ACIP reaffirms its support for the global polio eradication initiative and the use of OPV as the only vaccine recommended to eradicate polio from the remaining countries where polio is endemic.
Fault-tolerant wormhole routing in tori (1994)

We present a method to enhance wormhole routing algorithms for deadlock-free fault-tolerant routing in tori. We consider arbitrarily-located faulty blocks and assume only local knowledge of faults. Messages are routed via shortest paths when there are no faults, and this constraint is only slightly relaxed to facilitate routing in the presence of faults. The key concept we use is that, for each fault region, a fault ring consisting of fault free nodes and physical channels can be formed around it. These fault rings can be used to route messages around fault regions. We prove that at most four additional virtual channels are sufficient to make any fully-adaptive algorithm tolerant to multiple faulty blocks in torus networks. As an example of this technique, we present simulation results for a fully-adaptive algorithm and show that good performance can be obtained with as many as 10% links faulty.
Optimization of frame-like film bulk acoustic resonators for suppression of spurious lateral modes using finite element method (2005)

Film bulk acoustic resonators (FBARs) are comprised of a piezoelectric layer sandwiched between two electronically conductive layers that serve as electrodes. The portion of the piezoelectric film included between the overlap of the electrodes forms an acoustic cavity. The primary vibration mode of this cavity is that in which sound waves propagate in a longitudinal direction perpendicular to the plane of the electrodes. Unfortunately, the electric field also excites other spurious lateral vibration modes, These spurious lateral resonances near the main resonance of the resonator show up as a ripple in the pass band of filters. Frame-like FBARs have been proposed to eliminate the generation of the spurious lateral modes. The frame-like FBAR structures comprise a frame-like electrode confining a central area. The width and thickness of the frame-like electrode are arranged so that the displacement relating to the piezoelectrically excited strongest resonance mode is substantially uniform in the central area. In such a structure, the spurious resonances have often only a weak coupling. We apply the finite element method to investigate the effect of the frame-like FBARs on the suppression of lateral modes and find the optimal design of frame-like electrodes.
Highly efficient UHF‐band Si power MOSFET for RF power amplifiers (1994)

Abstract A low‐voltage/high‐efficiency Si power MOSFET has been developed for power amplifiers in mobile wire less telephone. Using submicrometer metal gate and self‐aligned drain contact structures, the on‐voltage and the output capacitance were reduced and the cutoff frequency was increased. As a result, compared with the conven tional device, the power‐added efficiency was increased by 10 percent. the power‐added efficiency was 60 percent at 1.5 GHz when the output power was 1 W. With 50‐kHz offset in digital modulation, leakage power between adjacent channels of 50 dBc, and output power of 0.8 W, the power‐added efficiency was 53 percent. It was confirmed that the Si MOSFET had an excellent linear power amplification characteristic in the ultrahigh‐frequency (UHF) band.

[Relationship between aflatoxin and sclerotia production in aspergillus flavus]. (1996)

Eighty strains of Aspergillus flavus (AF) isolated from grain produced in Zhejiang Province were studied experimentally on their abilities of sclerotia production, and 51.3% of the strains could produce sclerotia in Czapek solution agar containing 3% sodium nitrate at 30 C incubation for 12 days, with an average diameter of 827 +/- 131 microns, and no toxigenic S strain producing abundant small sclerotia was found. Most of the toxigenic strains producing sclerotia were L strain. There were no significant difference in the rates and amount of sclerotia production between toxigenic and a toxigenic strains. There was difference in diameter of sclerotia produced between them, with a smaller one in the toxigenic strains.

Design and Strand Tests of a Fusion Cable Composed of Coated Conductor Tapes (2013)

The design of a flat cable suitable for future fusion reactors has been carried out. The cable consists of twisted round strands, which are composed of tapes stacked between copper profiles. According to calculations, the strand twist pitch and the cable twist pitch should be at least 1.5 or 2 m long to limit the strain and thus the reduction of the critical current. A 4-m-long strand (Ø6.2 mm) was fabricated on a continuous stacking and soldering line to demonstrate that the scaling up to industrial production is feasible. The strand can carry about 940 A in self-field at 77 K. The critical current evolution under bending strain was measured but it turned out to be rather fragile in “hard” bending direction. Three types of joints between strands were also manufactured and tested at 77 K.
