Calibration and Compensation of the Scale Factor Errors in DTG POS

This paper proposes a calibration and compensation method of an inertial measurement unit (IMU) composed of two dynamically tuned gyros (DTGs) and three quartz accelerometers. Considering the DTG IMU for the position and orientation system (POS) used in the air remote sensing, it is found that the gyro scale factor has a hyperbolic relationship with the input angular rate and a linear relationship with the temperature shown from the experiments. Based on this, the equations of the gyro scale factor, the input angular velocity and the temperature are established by applying the least-square fit. Next, a hybrid multiposition calibration method of the IMU is given to estimate the error model parameters and compensate system errors. At last, a laboratory rate test and a car-mounted experiment are carried out to assess the efficiency of the proposed method. It is demonstrated from the experiment results that the attitude accuracy of the DTG POS can be improved with the calibration based on the compensation of scale factor errors.
Rituximab Pharmacokinetics in Patients With Rheumatoid Arthritis: B‐Cell Levels Do Not Correlate With Clinical Response

This study characterized the relationship between clinical response, serum rituximab concentrations, and peripheral B‐cell levels in patients with rheumatoid arthritis treated with rituximab. Data were analyzed from a double‐blind, phase IIa trial in which 161 patients with active rheumatoid arthritis despite continuing methotrexate were randomized to methotrexate alone (10–25 mg/wk), rituximab alone (single course: 1000 mg administered intravenously on days 1 and 15), rituximab plus cyclophosphamide (750 mg administered intravenously on days 3 and 17), or rituximab plus methotrexate. Serum samples for pharmacokinetic analysis were collected through 24 weeks, and peripheral circulating CD19+ B‐cell levels were measured through 48 weeks. All treatments were generally well tolerated, with no clinically relevant excess of adverse events leading to withdrawal among patients who received rituximab compared with those who received methotrexate alone. The proportions of patients who achieved an American College of Rheumatology score of 50 at week 24 were 13% (methotrexate alone), 33% (rituximab alone), 41% (rituximab plus cyclophosphamide), and 43% (rituximab plus methotrexate). Peripheral B‐cell depletion occurred by day 15 in all patients treated with rituximab. There was no relationship between B‐cell depletion and clinical response. Recovery of peripheral B cells was variable and showed no relationship with return of disease activity in patients who responded to rituximab. The mean terminal half‐life of rituximab was 19 to 22 days; pharmacokinetic parameters were similar whether rituximab was administered alone or with methotrexate or cyclophosphamide. Because the level of peripherally circulating B cells does not appear to correlate with a maintained clinical response in patients with rheumatoid arthritis, the timing of rituximab retreatment should be based on clinical symptoms rather than peripheral B‐cell levels.
Sécurité de la gestion dynamique des ressources basée sur la prise en compte des profils de consommation en ressources des machines virtuelles, dans un cloud IaaS. (Resource consumption profile-based attack detection in IaaS clouds)

La virtualisation materielle telle que mise en oeuvre dans le cloud computing, permet le partage de ressources materielles entre plusieurs machines virtuelles pouvant appartenir a differents utilisateurs. Ce partage des ressources constitue l’atout majeur de ces infrastructures,qui permet aux fournisseurs d’exploiter plus efficacement les ressources des centres de donnees, notamment a travers l’allocation dynamique des ressources. Cependant, le partage des ressources introduit de nouvelles contraintes de securite. Plusieurs travaux de l’etat de l’art ont demontre l’apparition de nouvelles strategies d’attaques propres aux infrastructures cloud computing, exploitant le partage des ressources. Neanmoins, il a aussi ete demontre qu’il est possible de tirer avantage de la position privilegiee de la couche de virtualisation pour offrir une meilleure securite que celle assuree dans les plate-formes traditionnelles d’hebergement en silo. Cette these poursuit deux axes de recherche complementaires. Le premier axe traite des nouvelles vulnerabilites liees aux infrastructures cloud computing. Nous avons demontre une attaque que nous appelons attaque par "migrations intempestives de machines virtuelles", dans laquelle un attaquant parvient a amener le systeme de gestion dynamique de ressources a migrer de facon abusive des machines virtuelles, par simple manipulation des quantites de ressources consommees par des machines virtuelles qui sont sous son controle. Nous avons demontre cette attaque sur une plate-forme constituee de cinq serveurs et analyse les conditions necessaires a son succes ainsi que l’exposition des clusters vis-a-vis de la vulnerabilite qu’elle exploite. Le second axe propose de tirer avantage de la position privilegiee de l’operateur qui dispose a la fois d’une vue multi-couches plus riche de l’utilisation des ressources et d’une vue plus globale des contextes d’execution des machines virtuelles, comparativement a la vue limitee de l’utilisateur, pour offrir une meilleure securite. Nous avons propose AMAD (Abusive VM Migration Attack Detection), un systeme de supervision, charge de detecter l’occurrence des attaques par migrations intempestives de machines virtuelles et d’identifier de facon automatique celles a l’origine de l’attaque. AMAD est implemente sur notre plate-forme d’experimentation et evalue a l’aide de traces de consommation de machines virtuelles collectees sur des clouds reels. Les resultats d’evaluation montrent qu’AMAD opere avec une bonne precision de detection.
Evolutionary matches of enzyme and transporter capacities to dietary substrate loads in the intestinal brush border.

Safety factors of enzymes and transporters are defined as the ratio of Vmax (maximal reaction rates at high substrate concentrations) to the reaction rate under actual physiological conditions. Although corresponding safety factors have been measured for macroscopic biological structures and for human-engineered structures, safety factors have been little studied at the molecular level. Some evolutionary considerations suggest that safety factors should be modestly in excess of 1.0 ("enough but not too much") and should tend to be similar for the various steps of a pathway consisting of two or more elements arranged in series. Hence we used a preparation of intact mouse small intestine to measure Vmax values (capacities) of brush-border sucrase (yielding glucose plus fructose) and of the brush-border glucose transporter, for comparison with each other and with dietary sucrose loads. Load was manipulated by varying dietary sucrose level or by studying lactating mice with increased energy requirements. Capacities both of sucrase and the glucose transporter increased with sucrose load (i.e., both proteins are inducible) and remained approximately matched to each other except on a carbohydrate-free diet. Their safety factors decreased from ca. 2.7 at low load to 1.0 at high load. Thus, neither sucrase nor the glucose transporter is the rate-limiting step for sucrose digestion; both steps are equally limiting. The modest safety factors and matched capacities must be genetically programmed through natural selection, with benefits of excess capacities being balanced against costs of biosynthetic energy and limited membrane space.
A family of asymptotically hyperbolic manifolds with arbitrary energy-momentum vectors

A family of non-radial solutions to the Yamabe equation, modeled on the hyperbolic space, is constructed using power series. As a result, we obtain a family of asymptotically hyperbolic metrics, with spherical conformal infinity, with scalar curvature greater than or equal to −n(n − 1), but which are a priori not complete. Moreover, any vector of Rn+1 is performed by an energy-momentun vector of one suitable metric of this family. They can in particular provide counter-examples to the positive energy-momentum theorem when one removes the completeness assumption.
Sarbanes Oxley Internal Control Requirements and Earnings Quality

This study investigates whether the internal control requirements of Section 302 and Section 404 of the Sarbanes-Oxley Act of 2002 are related to improved earnings quality. Using unexpected total and current accruals as measures of earnings quality, I test the association of internal control weaknesses disclosed under both sections and unexpected accruals for the disclosure year. I find level that the absolute level of unexpected accruals increases in the year internal control weaknesses are disclosed. This is consistent with an increase in earnings quality and suggests that in the internal control weaknesses disclosure year, management reverses, voluntarily or at the auditor's request, prior accruals that were too large. Comparing Sections 302 and 404 disclosures, I find that the magnitude of unexpected accruals is larger for Section 302 disclosures, implying that the nature and significance of the problems might more severe for Section 302 disclosures. For companies reporting an effective internal control in their Section 404 report, I find a decrease in the magnitude of unexpected accruals in the year of their first report. This result suggests that because of Section 404 formal internal control assessment process, firms improved their internal control and/or auditor increased their audit effort, resulting in management booking smaller accruals for events and transactions occurring in that year. Overall, my results suggest that the Sarbanes-Oxley Act internal control requirements resulted in an improved earnings quality.

Specifically, the paper views quality assurance in education as an effort and process of improving the general standard and value of education in order to benefit the recipients and the public at large. This is, in fact, the goals and targets which learners, teachers, staff and administration aspire to attain. The paper also reviews few
Serum mucin antigens casa and msa in tumors of the breast, ovary, lung, pancreas, bladder, colon, and prostate. A blind trial with 420 patients

Background. The tumor markers CASA (cancer‐associated serum antigen) and MSA (mammary serum antigen) have previously been shown to be useful in the clinical management of ovarian and breast carcinoma, respectively, but have not been assessed in other types of cancer. These assays were compared with carcinoem‐bryonic antigen (CEA) and prostate‐specific antigen (PSA) in a blind trial using sera from the Mayo Clinic‐National Cancer Institute (NCI) Diagnostic Serum Bank.

DEBT FINANCING AND FINANCIAL PERFORMANCE OF SMALL AND MEDIUM SIZE ENTERPRISES: EVIDENCE FROM KENYA

Debt ratios in large firms have been examined by a number of researchers while smaller firms have attracted less attention. The financial policies of large listed companies often differ from smaller firms because they raise funds by issuing debt or equity into capital markets. As such this study sought to investigate the effects of debt financing on the financial performance of SMEs. The objectives of the study were to determine the effects of long-term loans and short-term loans on SMEs financial performance. The study was guided by optimal capital structure theories. The study target 4122 SMEs in Eldoret town. Stratified sampling technique was used to select a sample size of 50 SME firms in Eldoret Town. The study collected quantitative secondary data from SMEs’ financial statements for three consecutive years (2011-2013). The reliability and validity of the data collection instrument was done using Cronbach Alpha. Multiple Regression analysis was used to test study hypothesis. The results revealed that short term loansβ=-0.304, and long term loans β=-0.155 had negative impact on financial performance of SMEs. The study concluded that long term and short term loans reduce financial performance of SMEs. The study recommends that SME should utilize loans, diversify for sustainability of revenue, keep proper books of accounts, offer clients sales contracts and lay down payment modes for trade credits, clearly stipulate the payment schedules, in order to deter poor credit and loan control policies and train their staff regularly while employing experienced internal and external auditors to improve on the internal control systems and book keeping.
A Compact Dual-Band Pattern Diversity Antenna by Dual-Band Reconfigurable Frequency-Selective Reflectors With a Minimum Number of Switches

A novel compact dual-band pattern diversity antenna is proposed. Dual-band reconfigurable frequency-selective reflectors are designed and applied to form a right-angle corner reflector antenna with reconfigurable patterns. With only one switch, the reconfigurable frequency-selective reflector can be controlled to be transmissive or reflective to vertically polarized waves at 2.45 and 5.25 GHz. By changing the combinations of the switch states, multiple patterns can be obtained. A dual-band feeding antenna designed via using the coupling effects is made to achieve well-matching conditions in all circumstances corresponding to various switch states at both frequencies. The measured results show good agreement with the calculated ones and demonstrate good pattern diversity virtues.
Inward Investment and Market Structure in an Open Developing Economy: A Case of Indiaâ€™s Manufacturing Sector

India announced series of liberalization measures since mid 1980s that inter-alia led to an unprecedented increase in the inflow of foreign direct investment (FDI). Evidence suggests that the rising inflows of FDI have influence on host country market structure though the direction is uncertain. Analytically, market structure has implications on the long run growth path of an economy through its effect on the allocation of economic resources among various economic activities including innovation. In this context, the objective of this paper is to analyze the bearing of FDI on market concentration with special reference to Indiaâ€™s manufacturing industries during the post-reform period. The study made use of firm level and product level data and panel regression techniques to fulfill the objective. The estimated model has shown a positive and significant influence of FDI on market concentration. If the result of the study is any indication, the increased inflow of FDI is likely to make Indiaâ€™s manufacturing sector more concentrated and calls for policy measures to mitigate undesirable outcomes of FDI inflows.
A Financial Leader’s Guide to Enhancing Long-Term Business Sustainability: ControllerFOCUS Model

The ControllerFOCUS concept was developed by Thammatucharee to provide controllers a strategic tool which will link together the operations and accounting objectives to accomplish the long-term business goals (Thammatucharee, 2009). The purpose of this paper is to provide a review of the construct of ControllerFOCUS concept, and to demonstrate the test result of the Controllership Index (CI) based on the researcher’s intervention in the case companies. The action research methodology was used at three selected companies through the questionnaire and observations. The results from this study showed fascinating levels of the controllership index indicating room for improvement in relevant areas, which supports the calls for changing roles of controller in supporting the business strategy implementation. For future research, the findings raise questions about the reliability of the CI and the possibility for adoption as a key performance indicator of the controller and the company performance for mutual strategic success.
Molecular diversity of Ca2+ channel beta subunits.

Introduction Voltage-gated Ca2+ channels have been extensively characterized in terms of their pharmacological, electrophysiological, biochemical, and molecular biological properties. Calcium channels are multisubunit complexes composed of an ion-conducting subunit, a ,, and smaller accessory subunits. Molecular cloning studies have concentrated on the a , subunit because it appears to determine the pharmacological and electrophysiological properties of the channel. In fact, expression of cloned a, subunits from skeletal muscle and cardiac muscle displayed I>-type CaZc-channel activity, whereas other distinct, yet related, a I subunits display N-type activity [l-31. So far, cDNAs from six a , genes have been cloned. Alignment of the deduced amino acid sequences reveals that these a,s are members of a superfamily that can be subdivided into I,-type and non-L-type Ca2+ channels. Despite experiments showing that the accessory subunits are capable of modulating the properties of a , subunits [2,4], cloning of these subunits has until recently received little attention. In this report, we summarize our cloning of Psubunit cDNAs derived from four distinct genes and present new data on alternatively spliced forms. We also summarize our expression studies using a representative member of each of these P subclasses.
A Transmit Power Control Algorithm for Data Acquisition Systems

Recently, wireless many-to-one networks have been attracting much attention and wireless sensor ad-hoc networks are applied to various applications. In ad-hoc networks using carrier sense multiple access with collision avoidance (CSMA/CA), the capacity is drastically decreased by the hidden node problem. In this paper, we assume a many-to-one network and propose a transmit power control (TPC) algorithm to avoid the hidden node problem. In our proposed TPC algorithm, a 1-hop area, a forced multi-hop area, and a multi-hop area are defined. All nodes in the 1-hop area adjust their transmit power as they can sense each other's transmit data, and all nodes in the forced multi-hop area and multi-hop area control their transmit power as they connect to a gateway (GW) with multi-hop and reduce the interference to nodes in the 1-hop area. The network capacity using the proposed TPC algorithm is evaluated by computer simulation. By this computer simulation, it is shown that the network capacity of TPC is better by about 2.6 times than that of No-TPC.
Contemporary Tourism and the Host Community in Less Developed Areas

The aim of this article is to re-examine the concept of community and of host and visitors' interaction in studies of tourism in less developed, remote areas. The re-examination proceeds along two lines: first, a critique of the concept of ‘community’, stressing the importance of its de-structuration into networks and linkages for the examination of the touristic process in those areas; and second, an examination of the changed nature of the host-tourist encounter under contemporary conditions of improved communications, the changing mix of tourists, and emergent ‘post-tourism’. This re-examination has significant implications for the study of the interface between tourist and host communities as well as for tourism management in less developed areas of the world.
The Performance Evaluation Research of Governmental Financial Investment in Science and Technology in Shandong Province Base on DEA

The academic circle and the government have paid close attention to the performance evaluation of governmental financial investment in science and technology. Having reviewed relevant literature home and abroad over the past years, the author has established an effective index system for such evaluation in line with the specific conditions of Shandong province. Besides, the author adopted Data Envelopment Analysis (DEA) to evaluate Shandong province's governmental financial investment in science and technology between 1998 and 2011. The author came up with such finding that in general the performance evaluation of governmental financial investment in science and technology of Shandong province was relatively effective, but problems remained such as the rather low proportion of governmental financial investment in science and technology in the overall provincial financial budget, and the deficient science and technology output, etc. KEYWORD: DEA; governmental financial investment in science and technology; performance evaluation
Insights into bunyavirus architecture from electron cryotomography of Uukuniemi virus

Bunyaviridae is a large family of viruses that have gained attention as “emerging viruses” because many members cause serious disease in humans, with an increasing number of outbreaks. These negative-strand RNA viruses possess a membrane envelope covered by glycoproteins. The virions are pleiomorphic and thus have not been amenable to structural characterization using common techniques that involve averaging of electron microscopic images. Here, we determined the three-dimensional structure of a member of the Bunyaviridae family by using electron cryotomography. The genome, incorporated as a complex with the nucleoprotein inside the virions, was seen as a thread-like structure partially interacting with the viral membrane. Although no ordered nucleocapsid was observed, lateral interactions between the two membrane glycoproteins determine the structure of the viral particles. In the most regular particles, the glycoprotein protrusions, or “spikes,” were seen to be arranged on an icosahedral lattice, with T = 12 triangulation. This arrangement has not yet been proven for a virus. Two distinctly different spike conformations were observed, which were shown to depend on pH. This finding is reminiscent of the fusion proteins of alpha-, flavi-, and influenza viruses, in which conformational changes occur in the low pH of the endosome to facilitate fusion of the viral and host membrane during viral entry.
