Conversion of high-Ievel sublanguage queries to account for database changes

Over the past few years, technological advances in database management have introduced many new research and development problems. The problem of "application migration" of a database management system is one of them. It can be grossly divided into two closely related subproblems: the problem of database translation and the problem of application program conversion due to database changes. There are many reasons for database reorganization and restructuring. Some of these are (1) the change of the use environment of a DBMS, (2) the upgrading of hardware and software facilities, (3) the change from one database system to another, (4) the installation of a new DBMS, (5) the modification of an existing system for efficiency purposes, and (6) the change of database semantics. The database translation problem has been tackled with some success by the works reported in References 7-9, 13-16, 18, 20-24, 29. Some database changes, both structural and semantic ones, may require that the set of application programs written for the old database be modified or converted to account for the changes either for semantic reasons or for efficiency purposes. A well-designed DBMS, which is data independent, should normally not be affected by the changes made on the physical structure and access strategy because these types of database changes can be handled simply by changing the mappings from the external model to the conceptual model and from the conceptual model to the internal model. 6 However, few existing database systems are truly data independent. Physical placement of data and access strategies are often carried into the application programs. 3,4,12 Furthermore, some semantic changes of database will inevitably cause changes in both the schema and the subschema which the data sublanguage directly interacts. Very often, the sublanguage statements as well as the host language statements need to be modified. As with the area of database translation, application program conversion could feasibly be implemented by the user or system programmer, however, the task is such an enormous one that the personnel's time is not effectively optimized. Therefore, a need for some type of program conversion system is definitely warranted.
An interactive Augmented Reality system: A prototype for industrial maintenance training applications

In this paper, we present an innovative Augmented Reality prototype designed for industrial education and training applications. The system uses an Optical See-Through HMD integrating a calibrated camera and a laser pointer to interactively augment an industrial object with virtual sequences designed to train a user for specific maintenance tasks. The training leverages user interactions by simply pointing on a specific object component. The architecture of our prototype involves two main vision-based modules : camera localization and user-interaction handling. The first module includes markerless trackers for camera localization, which can deal with partial occlusions and specular reflections on the metallic object surfaces. In the second module, we developed fast image processing methods for red laser dot tracking. By combining these processing elements, the proposed system is able to interactively augment in real time an industrial object making the learning process more interesting and intuitive.
Robust Trade in Lemons Markets

A buyer and seller have the opportunity to exchange an indivisible good at a prespecified price. Each agent may be imperfectly informed, in an arbitrary way, about both his own value for the good and the other agent’s value. An observer knows the joint distribution of the two agents’ values, but does not know their information structure. We determine what lower bounds the observer can confidently predict for the expected gains from trade that can be realized in equilibrium. In particular, we show that the worst-case information structure — that minimizes the realizable gains from trade — involves no information asymmetries.

A PLL with ultra low phase noise for millimeter wave applications

An ultra low noise phase locked loop (PLL) for millimeter wave applications is presented. The complete design includes a mixer type phase detector, a divide-by-32 frequency divider, a VCO and an off-chip active low pass filter. A method for the phase noise optimization of the PLL is described. The chip was designed using a 0.8 µm SiGe HBT technology. The frequency can be tuned from 29.9 GHz to 33.1 GHz. The output phase noise is around −112 dBc/Hz at 1 MHz offset.
Identification of suitable reference genes by quantitative real-time PCR for gene expression normalization in sunflower

Quantitative real-time PCR (qPCR) is currently the most accurate method for detecting differential gene expression, but depends greatly on normalization with stably expressed housekeeping genes. Transcriptomics analyses and experimental validation in different plant species have shown that the reliability of these endogenous controls can be influenced by, growth conditions and organs/tissues examined. Thus, reliable validation of reference genes is required to ensure proper normalization. This paper presents a systematic comparison of ten potential reference genes in sunflower: five commonly used genes (Actin, Elongation Factor1, Plastid-encode RNA polymerase, Tubulin, and Ubiquitin, as ACT, EF1, PEP, TUB, and UBQ respectively), as well as five new candidates (Translation initiation factor, MicroRNA precursors 171 and 156, Ask-interacting protein, and Protein of unknown function, as ETIF5, MIR171, MIR156, SKIP, and UNK2 respectively). Reference gene expression stability was examined by qPCR across 20 biological samples, representing different tissues at various developmental stages. Expression of all 10 genes was variable to some extent, but that of ACT, UNK2, and EF1 was overall the most stable. A combination of ETIF5/UNK2/EF1 would be appropriate to use as a reference panel for normalizing gene expression data among vegetative tissues, whereas the combination of ACT/MIR156/UNK2 is most suitable for reproductive tissues. Reference genes selected in this study were further validated by examining relative expression of ahas1, one of three acetohydroxyacid synthase genes of sunflower. Our identification and validation of suitable normalizer genes will be of use to ensure accurate results in future transcriptomics studies in this crop.
The Importance of the Mentor–Mentee Relationship in Women’s Desistance From Destructive Behaviors

According to the literature on desistance, the process of reentering society after imprisonment is distinct from the process of desistance as the former is a broader, institutional process that may influence the latter. Scholars have also acknowledged gendered differences in both reentry and desistance processes. Among the array of players in the lives of formerly incarcerated individuals, mentors have become an increasingly popular form of social support in postincarceration programs—particularly for women in reentry. Given the increasing interest in mentoring programs, this study uses semistructured interviews with mentors (n = 10) and clients (n = 11) in a women’s postincarceration mentoring program to assess the role of mentors in the reentry process and the desistance process. It was found that mentors aid in these processes by serving as facilitators of change for women who are open to such change and by facilitating in constructive behavioral adjustments.
Reconstruction of scene models from sparse 3D structure

In this paper we present a geometric theory for reconstruction of surface models from sparse 3D data captured from N camera views which are consistent with the data visibility. Sparse 3D measurements of real scenes are readily estimated from image sequences using structure-from-motion techniques. Currently there is no general method for reconstruction of 3D models of arbitrary scenes from sparse data. We introduce an algorithm for recursive integration of sparse 3D structure to obtain a consistent model. This algorithm is shown to converge to the real scene structure as the number of views increases and to have a computational cost which is linear in the number of views. Results are presented for real and synthetic image sequences which demonstrate correct reconstruction for scenes containing significant occlusions.
Optimization of Chi-FRBCS-BigDataCS Fuzzy Rule-Based Classification System

In this work we present an optimization of the only Fuzzy Rule-Based Classification System that is able to face Big Data classification problems to date, i.e., Chi-FRBCS-BigDataCS. The aim of this optimization is to speed up the learning process of the algorithm without affecting the model obtained. Our proposal is based on the usage of Look-Up-Tables to pre-compute the membership degrees of the different linguistic labels, avoiding millions of computations. Furthermore, we propose a new data flow that: 1) takes advantage of the sorting and merging phases of MapReduce to group duplicated/conflicting rules and avoids an exhaustive search over the rule base; 2) removes the bottleneck caused by the execution of a single reducer by supporting as many reducers as needed. These adaptations have shown a significant improvement in terms of runtime without altering the model obtained by Chi-FRBCS-BigDataCS.
Base station location for energy efficient in wireless sensor network

Energy constraints of wireless sensor networks are an important challenge. Data Transmission requires energy. Distance between origin and destination has an important role in energy consumption. In addition, the location of base station has a large impact on energy consumption and a specific method not proposed for it. In addition, a obtain model for location of base station proposed. Also a model for distributed clustering is presented by cluster heads. Eventually, a combination of discussed ideas is proposed to improve the energy consumption. The proposed ideas have been implemented over the LEACH-C protocol. Evaluation results show that the proposed methods have a better performance in energy consumption and lifetime of the network in comparison with similar methods.
Introduction of an intraoral bone-lengthening device.

It has been demonstrated that distraction osteogenesis is an effective clinical tool with applications for the entire human skeleton. Therapeutic exploitation in the correction of the asymmetrical and hypoplastic mandible has been reported previously. However, the main criticism of this technique has been the residual cutaneous scars resulting from the surgical incision and the path of the expansion device. In order to obviate the need for skin incisions, we have developed and demonstrated the feasibility of a miniaturized mandibular bone lengthener that is suitable for intraoral placement. Ten growing mongrel dogs were studied. Under general anesthesia, a buccal mucosal incision was made along the oblique line, and the body and ramus of the mandible were exposed in a supraperiosteal plane. Two 2.0-mm half-pins were placed percutaneously in the area of the angle of the mandible, and two other pins were placed 3.5 cm anteriorly. The clamps of the lengthening device were then attached to the half-pins in an intraoral position. An osteotomy was made by connecting percutaneously made drill holes between the clamps in a line positioned posterior to the third molar. The mucosa was closed loosely over the device. Distraction was commenced on the eighth postoperative day. The results were assessed with pre- and post-lengthening photographs, cephalograms, and CT scans with three-dimensional reconstruction. All animals demonstrated a contralateral cross-bite. The newly developed bone also was examined histologically. The intraoral method of mandibular lengthening offers the same advantages of extraoral lengthening but without the need for a cutaneous incision and resulting scar.
Mutations outside the YMDD motif in the P protein can also cause DHBV resistant to Lamivudine.

AIM To observe the Lamivudine resistance character of a DHBV strain in vitro and in vivo, and to analyze if the Lamivudine resistance character is caused by gene mutation or by abnormity of the Lamivudine metabolism. METHODS Congenitally DHBV-negative Guangdong brown ducks and duck embryo liver cells were respectively taken as animal and cell model. The Lamivudine-susceptive DHBV and Lamivudine-resistant DHBV (LRDHBV) were infected and Lamivudine was administrated according to the divided groups. The changes of DHBV quantity in the animal and cell model were tested. Three Lamivudine-resistant and two Lamivudine-susceptive DHBV complete genomes were successfully amplified, sequenced and then submitted to GenBank. All the DHBV complete sequences in the GenBank at present were taken to align with the three LRDHBV to analyze the mutational points related to the Lamivudine-resistant mutation. RESULTS Both the animal and cell model showed that the large and the small dosage Lamivudine have no significant inhibitory effect on the LRDHBV. Five sequences of DHBV complete genomes were successfully cloned. The GenBank accession numbers of the three sequences of LRDHBV are AY521226, AY521227, and AY433937. The two strains of Lamivudine-susceptive DHBV are AY392760 and AY536371. The correlated mutational points are KorR86Q and AorE591T in the P protein. CONCLUSION The Lamivudine resistance character of this DHBV strain is caused by genome mutation; the related mutational points are KorR86Q and AorE591T and have no relations with the YMDD motif mutation.
Core Loss Analysis and Calculation of Stator Permanent-Magnet Machine Considering DC-Biased Magnetic Induction

In this paper, core loss characteristics of stator permanent-magnet (PM) machines are analyzed and calculated, in which the unique dc-biased magnetic induction is taken into account. The flux density variation patterns in some key points in a doubly salient PM (DSPM) machine are analyzed by the two-dimensional time-stepping finite-element method. To calculate the core loss of stator and other minor hysteresis loops under dc magnetic bias, core loss characteristics of silicon steel sheet under dc-biased induction condition are first tested by a simple test system based on traditional Epstein frame and a functional relationship between the change of dc-biased induction and hysteresis loss is proposed. Two core loss calculation methods considering rotational magnetization based on flux density waveform are improved to take the influence of dc-biased magnetic induction into consideration. The calculation results are verified by experiments on a prototype DSPM machine. The conclusions are also applicable to other kinds of stator PM machines.

Photoemission study of electronic structure of the half-metallic ferromagnet Co3Sn2S2

Surface electronic structure of polycrystalline and single-crystalline samples of the half-metallic ferromagnet Co3Sn2S2 was studied by means of angle-resolved and core-level photoemissions. The experiments were performed in temperature regimes both above and below a Curie temperature of 176.9 K. The spectroscopic results are compared to local-spin density approximation band-structure calculations for the bulk samples. It is found that the surface sensitive experimental data are generally reproduced by the bulk computation suggesting that the theoretically predicted half-metallic properties of Co3Sn2S2 are retained at the surface.
Cytokine-Like Protein 1(Cytl1): A Potential Molecular Mediator in Embryo Implantation

Cytokine-like protein 1 (Cytl1), originally described as a protein expressed in CD34+ cells, was recently identified as a functional secreted protein involved in chondrogenesis and cartilage development. However, our knowledge of Cytl1 is still limited. Here, we determined the Cytl1 expression pattern regulated by ovarian hormones at both the mRNA and protein levels. We found that the endometrial expression of Cytl1 in mice was low before or on the first day of gestation, significantly increased during embryo implantation, and then decreased at the end of implantation. We investigated the effects of Cytl1 on endometrial cell proliferation, and the effects on the secretion of leukemia inhibitory factor (LIF) and heparin-binding epidermal growth factor (HB-EGF). We also explored the effect of Cytl1 on endometrial adhesion properties in cell-cell adhesion assays. Our findings demonstrated that Cytl1 is an ovarian hormone-dependent protein expressed in the endometrium that enhances the proliferation of HEC-1-A and RL95-2 cells, stimulates endometrial secretion of LIF and HB-EGF, and enhances the adhesion of HEC-1-A and RL95-2 cells to JAR spheroids. This study suggests that Cytl1 plays an active role in the regulation of embryo implantation.
AAV-HGFK1 and Ad-p53 cocktail therapy prolongs survival of mice with colon cancer

This study tried to evaluate the application of a novel cancer gene therapy using recombinant adeno-associated virus (AAV) carrying the kringle 1 domain of human hepatocyte growth factor (AAV-HGFK1) in combination with recombinant adenovirus carrying p53 gene (Ad-p53). BALB/c and nude mice models of colon cancer were established and the mice were treated with AAV-HGFK1 alone or in combination with Ad-p53. Combination of AAV-HGFK1 and Ad-p53 significantly prolonged the survival of the mice and also significantly inhibited primary and secondary tumor growth. Histochemical examination of the tumors revealed that AAV-HGFK1+Ad-p53 combinatorial treatment not only induced necrosis and apoptosis in the tumors but also suppressed tumor angiogenesis. The antiangiogenesis effect could likely be attributed to the ability of AAV-HGFK1+Ad-p53 viral cocktail to inhibit endothelial cell migration and proliferation. AAV-HGFK1+Ad-p53 also inhibited tumor cell growth in vitro by inhibiting epidermal growth factor receptor phosphorylation. Therefore, AAV-HGFK1+Ad-p53 cocktail therapy has a significantly higher therapeutic effect than AAV-HGFK1 or Ad-p53 alone and is a novel promising gene therapy for colon cancer.

Experimentelle Bestimmung von Dosisratenauf Reiseflughöhen im solaren Minimum

Die Strahlenexposition in der zivilen Luftfahrt resultiert aus der Hohenstrahlung, die ein naturlicher Bestandteil der Umwelt ist und 1912 erstmals von Victor Franz Hess beschrieben wurde. Sie entsteht durch Wechselwirkungen primarer energiereicher Teilchen aus dem All mit Atomen in den oberen Schichten der Erdatmosphare. Die Intensitat des Strahlungsfeldes, dem das fliegende Personal ausgesetzt ist, ist abhangig von der Hohe, dem Breitengrad und der Sonnenaktivitat, die mit der Anzahl der Sonnenflecken korreliert und in einem 11-Jahres- Zyklus variiert. Die von der Sonne ins Weltall emittierten Sonnenwinde erzeugen ein Magnetfeld, das in Erdnahe die einfallende primare galaktische Strahlung ablenkt und dadurch die Hohenstrahlung beeinflusst. Das erzeugte Magnetfeld schwankt mit der Aktivitat der Sonne dahingehend, dass wahrend eines Minimums der Sonnenaktivitat das Magnetfeld ebenfalls am geringsten ist, was auf der Erde und auf Reiseflughohen eine maximale Strahlenexposition bedingt. Der Schutz des Fliegenden Personals vor Exposition durch kosmische Strahlung ist mit der Neufassung der Strahlenschutzverfassung im Jahr 2001 erforderlich geworden. Seitdem werden die Dosiswerte fur das Fliegende Personal in Deutschland erfasst und uberwacht. Aufgrund der Tatsache, dass die Messung der Exposition auf jedem Flug aufwendig ware und hohe Kosten verursachen wurde, wird die Strahlenexposition von Crewmitgliedern mit Computerprogrammen ermittelt und auf individuellen Dosiskonten dokumentiert. Die Rechenprogramme sollten regelmasig durch Messungen auf Reiseflughohen verifiziert werden. Im auslaufenden solaren Minimum wurden vom DLR (Deutschen Zentrum fur Luft- und Raumfahrt) auf verschiedenen Flugrouten Messungen durchgefuhrt, mit deren Hilfe die Bestimmung von Dosisraten fur einen bestimmten Punkt auf der Route moglich ist. Ziel dieser Arbeit ist die Analyse und Auswertung der mit einem TEPC (Tissue Equivalent Proportional Counter), verschiedenen Halbleiterdosimetern des Typs MDU-Liulin (mobile dosimetry unit) und mehreren so genannten Bubble Detektoren experimentell ermittelten Dosisraten auf Reiseflughohen. Dabei sollen die Abhangigkeiten der Dosisrate unter der Bedingung des solaren Minimums dargestellt und eine Formel zur Ermittlung der Dosisrate auf Reiseflughohen bestimmt werden. Zusatzlich sollen mit Hilfe der experimentellen Daten, die operationell beim DLR berechneten Dosiswerte verifiziert und mogliche Abweichungen analysiert, sowie Ergebnisse der verschiedenen Messgerate gegenubergestellt werden.
Differences in the cerebrovascular anatomy of C57Black/6 and SV129 mice

THE vascular architecture of the brain of C57Black/6 and SV129 mice was studied following microvascular injection of carbon black stained latex. The dorsal brain surface was photographed to determine the number, diameter, and position of pial anastomotic vessels between the middle and anterior cerebral arteries. The mean number and diameter of anastomoses were not significantly different, but the line of anastomoses interconnecting the half way points of anastomotic vessels was located significantly closer to the midline in C57Black/6 mice, demonstrating that the middle cerebral artery had a larger vascular supplying territory than in SV129 mice. This explains the larger infarct volume previously reported in C57Black/6 mice, and raises concerns about the use of C57Black/6 and SV129 mice as parent strains for genetically modified animals in stroke research.
