Data Acquisition And Processing

The use of computers in the analytical electron microscopy today shows three different trends (1) automated image analysis with dedicated computer systems, (2) instrument control by microprocessors and (3) data acquisition and processing e.g. X-ray or EEL Spectroscopy.While image analysis in the T.E.M. usually needs a television chain to get a sequential transmission suitable as computer input, the STEM system already has this necessary facility. For the EM400T-STEM system therefore an interface was developed, that allows external control of the beam deflection in TEM as well as the control of the STEM probe and video signal/beam brightness on the STEM screen.The interface sends and receives analogue signals so that the transmission rate is determined by the convertors in the actual computer periphery.

Different Types

Research into the norm of internality ( Beauvois & Dubois, 1988 ) has shown that the expression of internal causal explanations is socially valued in social judgment. However, the value attributed to different types of internal explanations (e.g., efforts vs. traits) is far from homogeneous. This study used the Weiner (1979 ) tridimensional model to clarify the factors explaining the social utility attached to internal versus external explanations. Three dimensions were manipulated: locus of causality, controllability, and stability. Participants (N = 180 students) read the explanations expressed by appliants during a job interview. They then described the applicants on the French version of the revised causal dimension scale and rated their future professional success. Results indicated that internal-controllable explanations were the most valued. In addition, perceived internal and external control of explanations were significant predictors of judgments.

Two aspects of the problem of corruption are discussed in the article. The first one concerns the evaluation of the level of corruption. The method of measuring the size of business corruption market is described. The specifics of its estimation as well as its relation with the main macroeconomic indexes are discussed. The second aspect regards the strategies of corruption reduction. The importance of establishing external control over the bureaucracy is noted. The failure of institutions transplantation as the main method of economic transformations is pointed out. The gaps in social knowledge are discussed, which decrease effectiveness of institutional borrowings.

Programmable Integrated Photonics (PIP) is a new paradigm that aims at designing common integrated optical hardware configurations, which by suitable programming can implement a variety of functionalities that, in turn, can be exploited as basic operations in many application fields. Programmability enables by means of external control signals both chip reconfiguration for multifunction operation as well as chip stabilization against non-ideal operation due to fluctuations in environmental conditions and fabrication errors. Programming also allows activating parts of the chip, which are not essential for the implementation of a given functionality but can be of help in reducing noise levels through the diversion of undesired reflections. After some years where the Application Specific Photonic Integrated Circuit (ASPIC) paradigm has completely dominated the field of integrated optics, there is an increasing interest in PIP justified by the surge of a number of emerging applications that are and will be calling for true flexibility, reconfigurability as well as low-cost, compact and low-power consuming devices. This book aims to provide a comprehensive introduction to this emergent field covering aspects that range from the basic aspects of technologies and building photonic component blocks to the design alternatives and principles of complex programmable photonics circuits, their limiting factors, techniques for characterization and performance monitoring/control and their salient applications both in the classical as well as in the quantum information fields. The book concentrates and focuses mainly on the distinctive features of programmable photonics as compared to more traditional ASPIC approaches.

The locus of control dimensions among senior Pharm.D. students electing post-Pharm.D. residencies (N=15) are compared with first (N = 60) and second year (N = 55) Pharm.D. students, as well as with senior Pharm.D. students not electing residencies (N=14). Volunteer clinical faculty [hospital (N=27) and community (N = 23) pharmacy preceptors] and full-time clinical faculty (N = 22) are also compared. The Reid-Ware three-factor internal-external scale was completed by the study population. The dimensions measured were: self-control, social systems control, and fatalism. This study was undertaken to: 1. compare the locus of control dimensions among senior pharmacy students electing post-Pharm.D. residencies with senior pharmacy students not electing post-Pharm.D. residencies (and with other pharmacy students) and 2. compare the locus of control dimensions among senior pharmacy students electing and not electing post-Pharm. D. residencies (and with other pharmacy students) with their clinical, hospital, and community faculty to identify personality congruence (i.e., similarities, differences) which might facilitate the development of patient oriented-interactive behaviors necessary for clinical practice. Self-control (SC) was the major factor that generated the significant difference in the seven groups. The clinical (full-time) faculty group is significantly different from the student groups with the exception of the P-3, residency students. Over 50 percent of the P-3 residency group responded more like the faculty groups than like other students, with more P-3 residency students responding like clinical faculty than any other student or faculty group. The implication is that a similar personality profile exists in terms of internal/external control for the P-3 residency and full-time clinical faculty groups. Professors may have influenced, stimulated, or motivated those students most like themselves to enter a residency program. Based on the data, it would appear desirable to profile pharmacy students and give those who have a strong internal self-control factor encouragement to pursue post-graduate academic or residency programs and to retain as many of those individuals as possible in the areas of pharmacy that directly influence patient care and the pharmacist's role on the health care team.

Modeling and simulation play an important role in transportation networks analysis. In the literature, authors have proposed many traffic and mobility simulations, with different features and corresponding to different contexts and objectives. They notably consider different scales of simulations. The scales refer to the represented entities, as well as to the space and the time representation of the transportation environment. However, we often need to represent different scales in the same simulation, for instance to represent a neighborhood interacting with a wider region. In this paper, we advocate for the reuse of existing simulations to build a new multi-scale simulation. To do so, we propose a middleware model to couple independent mobility simulations, working at different scales. We consider all the necessary processing and workflow to allow for a coherent orchestration of these simulations. We also propose a prototype implementation of the middleware. The results show that such a middleware is capable of creating a new multi-scale mobility simulation from existing ones, while minimizing the incoherence between them. They also suggest that, to have a maximal benefit from the middleware, existing mobility simulation platforms should allow for an external control of the simulations, allowing for executing a time step several times if necessary.

Manipulation of ions and molecules by external control at the nanoscale is highly relevant to biomedical applications. We report a biocompatible electrode-embedded nanofluidic channel membrane designed for electrofluidic applications such as ionic field-effect transistors for implantable drug-delivery systems. Our nanofluidic membrane includes a polysilicon electrode electrically isolated by amorphous silicon carbide (a-SiC). The nanochannel gating performance was experimentally investigated based on the current-voltage (I-V) characteristics, leakage current, and power consumption in potassium chloride (KCl) electrolyte. We observed significant modulation of ionic diffusive transport of both positively and negatively charged ions under physical confinement of nanochannels, with low power consumption. To study the physical mechanism associated with the gating performance, we performed electrochemical impedance spectroscopy. The results showed that the flat band voltage and density of states were significantly low. In light of its remarkable performance in terms of ionic modulation and low power consumption, this new biocompatible nanofluidic membrane could lead to a new class of silicon implantable nanofluidic systems for tunable drug delivery and personalized medicine.
