A 1:2 Micro-Opto-Mechanical switch has been achieved using the combination of 2 technologies: `Integrated Optics' and `Micromachining on Silicon'. The commutation is obtained by means of the mechanical deflection of a cantilever beam driven by an electrostatic force. The first devices show promising characteristics.
EARTHING SYSTEM EVALUATION AND INFLUENCE ON PROTECTION PERFORMANCE IN RESONANTLY EARTHED MV NETWORKS (2009)

In Zagreb distribution area, Petersen coils are installed in five 110/10(20) kV substations. The advantages of resonantly earthed MV networks (continuous operation, arc self-extinction etc.) and some disadvantages (lower protection sensitivity) are well known. An overview of the procedure implemented before putting Peterson coils in operation is given, with emphasis on the earthing system evaluation, which has proved to be rather important. Protection testing should be performed for different types of faults. All data are given for two distribution areas in which Peterson coils have been recently installed.

An Innovative Design Approach To Reduce Drill String Fatigue (2004)

Abstract Fatigue and corrosion fatigue account for the majority of drill string failures.1,2 The complexity of fatigue and the drill string designer's inability to account for a great many factors affecting the mechanism make it impractical or impossible to accurately predict a component's fatigue life in cycles to failure. This paper describes the comparative design approach. This new approach normalizes many factors affecting fatigue that are generally unknown to the designer, allowing him or her to quantitatively compare the fatigue performance of available alternatives on the basis of what he or she does know. The method has already proven effective in field use.
Plasma metabolic profiling of dairy cows affected with clinical ketosis using LC/MS technology (2014)

Prioritization of online instructor roles: implications for competency‐based teacher education programs (2009)

Abstract Online instructors need to take on a multi‐dimensional role and to be an effective online educator they are required to possess a varied and wider range of competencies. Preparing teachers for online education involves preparing them for a wide variety of roles and developing related competencies. However, the extent of emphasis required to be placed on each of these roles or competencies during a teacher training program may vary according to its culture and the context. The investigation reported in this article obtained expert opinions with regard to the priority and criticality of eight online instructor roles identified in earlier research on online education. Pedagogical roles received the highest priority by the respondents, followed by professional, evaluator, social facilitator, technologist, advisor, administrator, and researcher roles. These results have implications for teacher education and further research pertaining to the context in India. Keywords: instructor competencyonline learningteacher preparation

Diamide: mechanisms of action and interactions with other sensitizers. (1978)

Diamide (diazenedicarboxylic acid bis [N,N′-dimethylamide]) is a hypoxic radiosensitizer that has at least two mechanisms of action, decreasing the survival curve shoulder at low concentrations and increasing the slope at high concentrations. Our present focus is on the shoulder effect, which we believe to be due to oxidation of cellular reducing species that normally effect rapid chemical repair of radiation-induced lesions.

A Novel Way To Synthesize Star Polymers in One Pot by ATRP of<i>N</i>-[2-(2-Bromoisobutyryloxy)ethyl]maleimide and Styrene (2003)

A one-pot approach to synthesize star polymers by atom transfer radical polymerization (ATRP) of N-[2-(2-bromoisobutyryloxy)ethyl]maleimide (BiBEMI) with a large excess of styrene (St) was described. It was based on preferential consumption of BiBEMI, as an inimer, through its copolymerization with St, to form a branched intermediate in situ as the multifunctional core, which initiated homopolymerization of the excessive St to produce a star polymer. The kinetic studies exhibited two polymerization stages corresponding to the formation of the core with a faster propagating rate and the formation of arms by homopolymerization of St, respectively. 1H NMR spectra showed that in core formation stage random copolymer was formed. Analysis of the basic hydrolyzed products of the core by MALDI−TOF mass spectroscopy confirmed the branched structure of the core. A “6”-shaped polystyrene was also formed simultaneously, and its structure was confirmed by MALDI−TOF mass spectroscopy. Lowering the reaction temperature and using less excessive St could decrease the content of this polymer. Star polymers were characterized by 1H NMR, hydrolysis, and intrinsic viscosity.
Design and fabrication of an off-axis see-through head-mounted display with an x–y polynomial surface (2010)

An off-axis optical system with an x-y polynomial surface for a see-through head-mounted display (HMD) is presented. With the use of an x-y polynomial surface, an off-axis see-through HMD system with one tilted spherical combiner and six relay optical lenses is designed. An off-axis see-through HMD with a 15 mm exit pupil, a 40 degrees x 30 degrees FOV, and 70 mm eye relief is achieved. Furthermore, a binocular off-axis see-through HMD prototype is fabricated and the performance of the system is experimentally tested; 972 cd/m(2) of luminance is measured at the position of the exit pupil of the HMD. A typical augmented reality image captured outdoors with the HMD prototype is also demonstrated.

Software and Hardware Co-designed Multi-level TLBs for Chip Multiprocessors (2011)

Translation Look aside Buffers (TLBs) have a significant impact on system performance. Numerous prior studies focus on TLBs design for uniprocessors. As the advent of chip multiprocessors (CMPs), we need shift to TLBs for chip multiprocessors. This paper presents a software-implemented level-two TLB -- SL2-TLB which is a shared level-two TLB for multiprocessors. It not only reduces the cost of TLB refill handler for every processor core, but also reduces the redundant TLB misses' cost for CMPs effectively. Today, CMPs typically employ private per-core TLBs. SL2-TLB together with the hardware TLBs make up a software-hardware co-designed multilevel TLB system which brings great benefit to system performance while avoiding changing the hardware TLB. So it is a convenient and efficient method for CMPs' TLB performance improvement. The benefit brought by SL2-TLB to SPECCPU2000 is less than that to SPECCPU2006, about 5% and 7% separately. Therein to, the average performance improvement of SPECint 2006 reaches about 12.7%. That is because the overhead for TLB refill is small when the cache is large enough to avoid a miss as walking the page table of applications with small memory footprints. The further optimization for SL2-TLB is kept the SL2-TLB table stay in L2 cache forever by the cache locking scheme. SL2-TLB together with cache locking scheme improves the performances by over 13% for SPECint 2006. And an average performance improvement of over 7% is brought to the new emerging parallel benchmark suite-Princeton Application Repository for Shared-Memory Computers (PARSEC). And all the above evaluations are done on Godson-3 processors which is the latest generation of China's most powerful microprocessor family.

Monitoring and Troubleshooting in Operational IP-TV System (2007)

When deploying large scale of QoS guaranteed IP-TV services over Triple-Play networks, there is a growing demand to access to the live network services, monitor in real time the broadcast chains, acquire the dynamic network parameters to ensure an uninterrupted, high quality service. Considering the difference of IP packet switching network and the de-facto transport stream (TS) standard of broadcast digital video network, this paper describes design consideration and implementation of a powerful embedded IP-TV monitor for real time monitoring the IP-TV QoS and using this equipment to construct a payload-aware monitoring network for on-line troubleshooting when the QoS deteriorate. The monitor should be designed to have ability to monitor and troubleshoot the blended combination of network status and digital TV quality in real time and cross layer way, meanwhile the procedures of monitoring does not interfere with the on-line services. This monitor can be deployed in the networks to measure the three ultimate metrics: IP cumulative jitter, packet loss and MPEG TS errors and provide helpful information about the network and service when service failed. Implementation and experimental results show promise of being practical in the real IP-TV trial networks.
Is thioredoxin the physiological vitamin K epoxide reducing agent? (1992)

E. coli thioredoxin plus thioredoxin reductase have previously been shown to replace dithiothreitol as the electron donor for mammalian liver microsomal vitamin K epoxide reduction in vitro. Such activity is dependent on detergent disruption of the microsomal membrane integrity. A previously characterized salicylate-inhibitable pathway for electron transfer from endogenous cytosolic reducing agents to the microsomal epoxide reducing warfarin-inhibitable enzyme is not inhibited by known alternate substrates and inhibitors of the thioredoxin system nor by antibodies against thioredoxin.
Extraction of Contextual Metadata from File System Interactions. (2009)

There is a diurnal variation in the mean incidence and amplitude of fetal breathing movements (FBMs) in sheep after approximately 120 days gestation. To determine whether this variation is caused by diurnal fluctuations in plasma glucose or prostaglandin (PG) concentrations, we studied two groups of pregnant sheep fed either once daily at 1100 h or every 2 h for 24 h. Maternal and fetal blood samples were taken every 2 h from 0900 to 0900 h the next day for assay of plasma glucose and PGE2 and PGF2 alpha concentrations. FBMs were recorded throughout the 24 h. The mean fetal plasma glucose concentrations of the once-daily and multifed groups were not different, but there was a significant difference between the two groups in the 24-h pattern of fetal glucose concentrations. In the once-daily fed group, plasma glucose concentrations reached a peak 8 h after maternal feeding and then declined, whereas in the multifed group, fetal plasma glucose concentrations reached a plateau and were constant from 1300 to 0900 h the next day. Fetal plasma PGE2 and PGF2 alpha concentrations did not show a significant change with time of day in either group. There was a significant diurnal variation in the incidence and amplitude of FBMs in each of the two feeding groups, and the 24-h pattern of FBMs did not differ significantly between groups. Therefore it would appear that the diurnal variation of FBMs is not a consequence of the maternal feeding regimen or diurnal changes in plasma glucose or PG concentrations.

AEBP1 upregulation confers acquired resistance to BRAF (V600E) inhibition in melanoma (2013)

An activating BRAF (V600E) kinase mutation occurs in approximately half of melanomas. Recent clinical studies have demonstrated that vemurafenib (PLX4032) and dabrafenib, potent and selective inhibitors of mutant v-raf murine sarcoma viral oncogene homolog B1 (BRAF), exhibit remarkable activities in patients with V600 BRAF mutant melanomas. However, acquired drug resistance invariably develops after the initial treatment. Identification of acquired resistance mechanisms may inform the development of new therapies that elicit long-term responses of melanomas to BRAF inhibitors. Here we report that increased expression of AEBP1 (adipocyte enhancer-binding protein 1) confers acquired resistance to BRAF inhibition in melanoma. AEBP1 is shown to be highly upregulated in PLX4032-resistant melanoma cells because of the hyperactivation of the PI3K/Akt-cAMP response element-binding protein (CREB) signaling pathway. This upregulates AEBP1 expression and thus leads to the activation of NF-κB via accelerating IκBa degradation. In addition, inhibition of the PI3K/Akt-CREB-AEBP1-NF-κB pathway greatly reverses the PLX4032-resistant phenotype of melanoma cells. Furthermore, increased expression of AEBP1 is validated in post-treatment tumors in patients with acquired resistance to BRAF inhibitor. Therefore, these results reveal a novel PI3K/Akt-CREB-AEBP1-NF-κB pathway whose activation contributes to acquired resistance to BRAF inhibition, and suggest that this pathway, particularly AEBP1, may represent a novel therapeutic target for treating BRAF inhibitor-resistant melanoma.
A 12-b, 10-MHz, 250-mW CMOS A/D converter (1996)

A 12-b, 10-MHz, 250-mW, four-stage analog-to-digital converter (ADC) was implemented using a 0.8-/spl mu/m p-well CMOS technology. The ADC based on a digitally calibrated multiplying digital-to-analog converter (MDAC) selectively employs a binary-weighted capacitor array in the front-end stage and a unit-capacitor array in the remaining back-end stages to obtain 12 b level linearity while maintaining high yield. All the analog and digital circuit functional blocks are fully integrated on a single chip, which occupies a die area of 15 mm/sup 2/ (4.2 mm/spl times/3.6 mm). Measured differential nonlinearity (DNL) and integral nonlinearity (INL) of the prototype are less than /spl plusmn/0.8 LSB and /spl plusmn/1.8 LSB, respectively.
THE INFLUENCE OF SOME OESTROGENS AND PROGESTOGENS ON THE ACTIVITY OF GLYCERYLPHOSPHORYLCHOLINE DIESTERASE IN RINSINGS OF THE RAT UTERUS (1964)

SUMMARY The effects of some oestrogens and progestogens on the glycerylphosphorylcholine (GPC) diesterase activity and the protein concentration of rinsings of the rat uterus have been studied in relation to changes in the weight of this organ. Both enzyme activity and protein concentration were increased by subcutaneous administration of oestradiol-3:17β, oestriol, oestrone and diethylstilboestrol to ovariectomized rats and these responses were inhibited by progesterone and 17α-ethyl-19-nortestosterone. The GPC diesterase activity and protein content of uterine rinsings were affected independently of each other and of changes in the uterine weight.
An Integrated Circuit/Packet Switching Local Area Network - Performance Analysis and Comparison of Strategies. (1986)

Abstract A new inhouse communication system is suggested integrating circuit switched services with variable bit-rate as well as packet-switched services with variable throughput rate. The advantages of LANs and PBXes will be combined in the new architecture. In this paper several strategies to achieve the integration of both switching principles on a ring system are presented. Performance evaluation is done by means of maximum PS-throughput calculation as well as simulations of the detailed system, resulting in mean waiting times for PS-messages under different offered PS- and CS-traffic load conditions
Emerging Understanding of the Mechanism of Action for Dimethyl Fumarate in the Treatment of Multiple Sclerosis (2018)

Dimethyl fumarate (DMF) is an effective treatment option for relapsing-remitting multiple sclerosis (MS), but its therapeutic mechanism of action has not been fully elucidated. A better understanding of its mechanism will allow for the development of assays to monitor its clinical efficacy and safety in patients, as well as guide the development of the next generation of therapies for MS. In order to build the foundation for determining its mechanism, we reviewed the manner in which DMF alters lymphocyte subsets in MS patients, its impact on clinical efficacy and safety, as well as its molecular effects in cellular and animal models. DMF decreases absolute lymphocyte counts, but does not affect all subsets uniformly. CD8<sup>+</sup> T-cells are the most profoundly affected, but reduction also occurs in the CD4<sup>+</sup> population, particularly within the pro-inflammatory T-helper Th1 and Th17 subsets, creating a bias toward more anti-inflammatory Th2 and regulatory subsets. Similarly, B-lymphocyte, myeloid, and natural killer populations are also shifted toward a more anti-inflammatory state. <i>In vitro</i> and animal models demonstrate a role for DMF within the central nervous system (CNS) in promoting neuronal survival in an Nrf2 pathway-dependent manner. However, the impact of DMF directly within the CNS of MS patients remains largely unknown.
Economic impacts of reduced milk production associated with papillomatous digital dermatitis in dairy cows in the USA (2006)

The goal of this study was to measure the economic impacts of reduced milk production associated with papillomatous digital dermatitis (PDD) in dairy cows in the USA, and of specific risk factors for PDD, in 1996. The method applied was an economic-welfare analysis of producer and consumer surplus, with the GUM Workbench used to analyse uncertainties in the measurements. Reduced milk production associated with PDD was found to reduce consumer surplus by Dollars 750 million +/- Dollars 580 million, and to increase the economic surplus of producers by Dollars 560 million +/- Dollars 470 million, with a net economic loss of Dollars 190 million +/- Dollars 130 million. An examination of the economic effects of specific epidemiologic risk factors for PDD showed that having dairy cows that were not born on the operation had important economic consequences associated with the disease, as did the type of land to which dairy cows had access during the winter months and the type of flooring on which cows walked. Washing hoof-trimming equipment between cows was an important biosecurity measure that was associated with reduced PDD. The epidemiologic model used also implicated hoof trimmers who trimmed cattle hooves on other operations as having an important economic impact associated with this disease, although this finding may have been erroneous.
Domain-Specific Language Design Requires Feature Descriptions (2002)

A domain-specific language (DSL) provides a notation tailored towards an application domain and is based on the relevant concepts and features of that domain. As such, a DSL is a means to describe and generate members of a family of programs in the domain. A prerequisite for the design of a DSL is a detailed analysis and structuring of the application domain. Graphical feature diagrams have been proposed to organize the dependencies between such features, and to indicate which ones are common to all family members and which ones vary. In this paper, we study feature diagrams in more details, as well as their relationship to domain-specific languages. We propose the Feature Description Language (FDL), a textual language to describe features. We explore automated manipulation of feature descriptions such as normalization, expansion to disjunctive normal form, variability computation and constraint satisfaction. Feature descriptions can be directly mapped to UML diagrams which in their turn can be used for Java code generation. The value of FDL is assessed via a case study in the use and expressiveness of feature descriptions for the area of documentation generators.
