Carbapenemase inhibitors

&NA; Carbapenemase inhibitors play a critically important role in prevention of carbapenem resistance. In the current review, based on studied articles from PubMed, Google Scholar and Scopus, we summarize the current state of carbapenemase inhibitors and their importance in clinical use. Clavulanic acid, sulbactam and tazobactam are traditional &bgr;-lactam\class A carbapenemase inhibitors. Avibactam; relebactam and boronic acid-based inhibitors including PRX7009, &bgr;-lactamase inhibitory protein II, Zinc01807204 and Zinc02318494 compounds are also novel and non-&bgr;-lactam\class A carbapenemase inhibitors. In the case of metallo-&bgr;-lactamase inhibitors, EDTA, thioester derivatives, propionic acid, maleic acid, succinic acid and phthalic acid derivatives are reputed inhibitors. There are limited oxacillinase (OXA) inhibitors because of the variability in amino acid sequence of OXAs. Boronic acid-based compounds and penicillin sulfone derivatives are promising candidates for the development of OXA-carbapenemase inhibitors. Although the prospect for non-&bgr;-lactam inhibitors is better, but the available inhibitors are mostly developed against plasmid-mediated carbapenemases, and other clinically important carbapenemases are increasing throughout the world. Despite in-vitro activity of aforementioned inhibitors, few of them are in clinical use. Side effects followed by inhibitors and also carbapenemase inhibitor resistance indicate the clinical need for development of novel, effective and nontoxic inhibitors to overcome carbapenemase-mediated resistance in bacteria.
Improving Transfer of Learning in a Computer Based Classroom.

This report describes a program for improving the transfer of the learning of different techniques used in computer applications. The targeted population consisted of sophomores and juniors in a suburban high school in a middle class community. The problem was documented through teacher surveys, student surveys, anecdotal records and behavioral checklists. Analysis of probable causes revealed that students lack motivation, have an inability to organize their thinking, and lack confidence and prior knowledge of computer applications. Faculty reported that students have inability to share ideas and knowledge, that they easily give up on a problem, and have difficulty transferring techniques from one problem to another. A review of research literature suggested that students are not taught how to transfer and that transfer will happen on its own. Students do not have a mental working model of the actual workplace setting and do not understand how their present learning will transfer into a real world problem. A review of solutions strategies by researchers in the field, combined with an analysis of the problem setting resulted in the selection of three major categories of intervention: provide a real world problem for the students to solve, demonstrate computer application techniques that transfer from one application to another, and make the students more aware of their own thinking. Post intervention data indicated that the targeted students demonstrated an improvement of their transfer of learning skills. (Contains 26 references.)

Information transfer in a flocking robot swarm

In this dissertation, we propose and study methods for information transfer within a swarm of mobile robots that coordinately move, or flock, in a common direction. We define information transfer as the process whereby robots share directional information in order to coordinate their heading direction. We identify two paradigms of information transfer: explicit information transfer and implicit information transfer. In explicit information transfer, directional information is transferred via communication. Explicit information transfer requires mobile robots equipped with a a communication device. We propose novel communication strategies for explicit information transfer, and we perform flocking experiments in different situations: with one or two desired directions of motion that can be static or change over time. We perform experiments in simulation and with real robots. Furthermore, we show that the same explicit information transfer strategies can also be applied to another collective behavior: collective transport with obstacle avoidance. In implicit information transfer, directional information is transferred without communication. We show that a simple motion control method is sufficient to guarantee cohesive and aligned motion without resorting to communication or elaboratesensing. We analyze the motion control method for its capability to achieve flocking with and without a desired direction of motion, both in simulation and using real robots. Furthermore, to better understand its underlying mechanism, we study thismethod using tools of statistical physics, showing that the process can be explained in terms of non-linear elasticity and energy-cascading dynamics.
Rotational quadratic function neural networks

The authors present a novel architecture, known as the rotational quadratic function neuron (RQFN), to implement the quadratic function neuron (QFN). Although with some loss in the degree of freedom in the boundary formation, RQFN possesses some attributes which are unique when compared to QFN. In particular, the architecture of RQFN is modular, which facilitates VLSI implementation. Moreover, by replacing QFN by RQFN in a multilayer perceptron (MP), the fan-in and the interconnection volume are reduced to that of MP utilizing linear neurons. In terms of learning, RQFN also offers varieties such as the separate learning paradigm and the constrained learning paradigm. Single-layer MP utilizing RQFNs have been demonstrated to form more desirable boundaries than the normal MP. This is essential in the scenario where either the closure of the boundary or boundaries of higher orders are required. <<ETX>>
Dependability where the mobile world meets the enterprise world

Maji, Amiya K. Ph.D., Purdue University, May 2015. Dependability where the Mobile World Meets the Enterprise World. Major Professor: Saurabh Bagchi. As we move toward increasingly larger scales of computing, complexity of systems and networks has increased manifold leading to massive failures of cloud providers (Amazon Cloudfront, November 2014) and geographically localized outages of cellular services (T-Mobile, June 2014). In this dissertation, we investigate the dependability aspects of two of the most prevalent computing platforms today, namely, smartphones and cloud computing. These two seemingly disparate platforms are part of a cohesive story—they interact to provide end-to-end services which are increasingly being delivered over mobile platforms, examples being iCloud, Google Drive and their smartphone counterparts iPhone and Android. In one of the early work on characterizing failures in dominant mobile OSes, we analyzed bug repositories of Android and Symbian and found similarities in their failure modes [ISSRE2010]. We also presented a classification of root causes and quantified the impact of ease of customizing the smartphones on system reliability. Our evaluation of Inter-Component Communication in Android [DSN2012] show an alarming number of exception handling errors where a phone may be crashed by passing it malformed component invocation messages, even from unprivileged applications. In this work, we also suggest language extensions that can mitigate these problems. Mobile applications today are increasingly being used to interact with enterpriseclass web services commonly hosted in virtualized environments. Virutalization suffers from the problem of imperfect performance isolation where contention for lowlevel hardware resources can impact application performance. Through a set of rigorous experiments in a private cloud testbed and in EC2, we show that interference
Steady modes and sliding modes in the relay control systems with time delay

The relay control systems with time delay are considered. We show that the time delay does not allow to realize an ideal sliding mode, but implies oscillations, whose stability is determined by one discrete parameter-oscillation frequency. Any motion of scalar discontinuous delay system turns into a steady mode-a motion with a constant frequency. Such steady modes have all properties of sliding modes. The problem of stability of steady modes in three main cases autonomous, quasiautonomous and periodic is considered. It is shown that in autonomous and quasiautonomous cases only steady modes with zero frequency are stable. At the same time this modes are non-asymptotically stable. The structural stability of steady modes in the periodic case is investigated. The resonances are singled out. The existence of the slow stable periodic solution of the multidimensional singularly perturbed relay system with time delay is proved. At last, we design a direct adaptive control of relay type with time delay that extinguishes parasite auto-oscillations in this model.
Inter-space and intra-space transformations for sensor array processing

The use of inter-space and intra-space transformations are considered for improving the transient performance of the LMS processor and reducing the dimension of the weight vector, respectively. Within the context of sensor array processing, a subband LMS algorithm is described for inter-space processing and a cross-spectral subspace selection metric is presented for intraspace transformations. The transform operators may be combined with the generalized sidelobe canceller signal blocking matrix. <<ETX>>
Modelling Perceptual Quality and Visual Saliency for Image and Video Communications

The evolution of advanced radio transmission technologies for third and future generation mobile radio systems has paved the way for the delivery of mobile multimedia services. This is further enabled through contemporary video coding standards, such as H.264/AVC, allowing wireless image and video applications to become a reality on modern mobile devices. The extensive amount of data needed to represent the visual content and the scarce channel bandwidth constitute great challenges for network operators to deliver an intended quality of service. Appropriate metrics are thus instrumental for service providers to monitor the quality as experienced by the end user. This thesis focuses on subjective and objective assessment methods of perceived visual quality in image and video communication. The content of the thesis can be broadly divided into four parts. Firstly, the focus is on the development of image quality metrics that predict perceived quality degradations due to transmission errors. The metrics follow the reduced-reference approach, thus, allowing to measure quality loss during image communication with only little overhead as side information. The metrics are designed and validated using subjective quality ratings from two experiments. The distortion assessment performance is further demonstrated through an application for filter design. The second part of the thesis then investigates various methodologies to further improve the quality prediction performance of the metrics. In this respect, several properties of the human visual system are investigated and incorporated into the metric design. It is shown that the quality prediction performance can be considerably improved using these methodologies. The third part is devoted to analysing the impact of the complex distortion patterns on the overall perceived quality, following two goals. Firstly, the confidence of human observers is analysed to identify the difficulties during assessment of the distorted images, showing, that indeed the level of confidence is highly dependent on the level of visual quality. Secondly, the impact of content saliency on the perceived quality is identified using region-of-interest selections and eye tracking data from two independent subjective experiments. It is revealed, that the saliency of the distortion region indeed has an impact on the overall quality perception and also on the viewing behaviour of human observers when rating image quality. Finally, the quality perception of H.264/AVC coded video containing packet loss is analysed based on the results of a combined subjective video quality and eye tracking experiment. It is shown that the distortion location in relation to the content saliency has a tremendous impact on the overall perceived quality. Based on these findings, a framework for saliency aware video quality assessment is proposed that strongly improves the quality prediction performance of existing video quality metrics.
Speech signal analysis and synthesis via Fourier-Bessel representation

This paper concerns with the Fourier-Bessel (FB) representation of speech signal and its application in speech analysis and synthesis. The Fourier-Bessel representation of the speech signal is obtained using Bessel function as a basis set. This is accomplished by determining the Fourier-Bessel series expansion coefficients Cmof the short-time speech signal at successive instants of time. The successive sets of coefficients are then displayed in time-index-coefficient (t-m-Cm) plot. The patterns on the plot yield discriminating feature for the spoken words and may be used as speech feature for speech recognition. Unlike the spectrogram which represents the spectral magnitude content of the signal, the (t-m-Cm) plot is the complete characterization of the time-domain signal. It is demonstrated that good quality intelligible speech signal can be reconstructed using only a small portion of information contained in the (t-m-Cm) plots. Examples showing discriminating (t-m-CM) plots and reconstructed speech using only a small portion of information in the plot are given for vowel, stop, fricative and affricate.

Review: Nicholas Rescher, Plausible Reasoning. An Introduction to the Theory and Practice of Plausibilistic Inference

to be a "quasi-universal" disposition. The having of <j> nomically entails the having of tj/ iff (Vx)(4>? x D (ip/4>)x). A counterfactual of the form "if it had been that <£x, then it would have been that i/rx " is taken to be true iff x has the dispositional property (il>/<f>). In the final chapter the author argues that a "conceptualistic" approach to necessity and possibility is the only viable one. It is maintained that any careful analysis of the meaning of modal notions ultimately requires the introduction of mental capacities. Consider a dispositional property. We characterize it in terms of what an individual that exemplifies it would do in certain non-actual circumstances. This characterization introduces a kind of hypothetical consideration which, the author feels, can be explicated only in mentalistic terms. An analysis of "what would happen if" must ultimately be given in terms of what it is possible for a mind to conceive. Talk about possibility can thus be reduced to talk about the actual capabilities of actual minds. Against this one could argue that there is an important sense in which at least some modal notions are mind independent. To say e.g. that x is water soluble is to predicate a property of x. It is true that this property is often characterized by talk about what x would do if placed in water. It does not follow from this, however, that the predicated property is "mind dependent. " It does not follow that the truth-conditions for 'x is water soluble' must contain a reference to mental capacities. Two final points. As indicated, properties play a fundamental role in the proposed theory. Unfortunately there is very little discussion of, for example, the problems surrounding the individuation of properties. Since supernumeraries are individuated via their properties, this omission is an important one. The author's use of the phrase 'mere possibility' is inconsistent. Initially a mere possibility is a possibility involving a supernumerary. In the last chapter a mere possibility covers any possible but non-actual entity. Although not a serious error, this does lead to some easily avoidable confusion.
Adjustment of the primitive parameters of the simulated annealing heuristic

In this paper, the best setting for primitive parameters of simulated annealing fitted on traveling salesman problem is selected by using the design of experiment, response surface methodology and goal programming. There are 6 parameters in that 3 of them are tuned on two-up and down- levels. The three others are tuned on multi levels. A factorial plan 2 3 with 4 central points is used for two-level parameters. Multilevel parameters are tuned by design of experiment. At the end a goal programming model is used to select the best parameters.
MPEG-2 over ATM for video dial tone networks: issues and strategies

Market growth for PC multimedia and digital video owes largely to the rapid adoption of ISO compression standards by the industry. For video dial tone (VDT) services, the MPEG-2 set of standards have clearly emerged as the preferred coding method for VDT networks. For point-to-point switched video or multimedia connections, ATM has emerged as the technology of choice for switching and transport. This article describes how compressed digital video is transported over a VDT network, what some of the issues are, and how they are being addressed by the industry. It describes a generic VDT reference architecture, and the delivery method of video and multimedia information over such a network. >
Motis - an mos timing simulator

A new circuit simulator is described which combines the gate-to-gate signal propagation technique used in logic simulators with detailed device representation and circuit analysis at the gate level. MOTIS is specialized for analyses of MOS logic circuits during the prelayout and postlayout phases of a design. The device modeling takes account of the back-gate bias effects and the bidirectionality of transmission gates. The simulation mechanism and the detailed device modeling lead to simulation of the dependence of propagation delays on input waveforms. The loading and device capacitances are assumed to be constant and bootstrapping effects are not simulated. The simulator has been implemented on a minicomputer having a 32K-word memory of 16-bit words, a disk module, and a storage CRT/keyboard terminal. This configuration allows simulation of circuits having 1000 gates with an operational speed of approximately 2 ms of real time per gate per nanosecond of circuit time.
A Novel Device for Measuring Forces in Endoluminal Procedures

In this paper a simple but effective measuring system for endoluminal procedures is presented. The device allows measuring forces during the endoluminal manipulation of tissues with a standard surgical instrument for laparoscopic procedures. The force measurement is performed by recording both the forces applied directly by the surgeon at the instrument handle and the reaction forces on the access port. The measuring system was used to measure the forces necessary for appropriate surgical manipulation of tissues during transanal endoscopic microsurgery (TEM). Ex-vivo and in-vivo measurements were performed, reported and discussed. The obtained data can be used for developing and appropriately dimensioning novel dedicated instrumentation for TEM procedures.
Applications of fuzzy logic to the control of an autonomous underwater vehicle

Describes applications of fuzzy logic to the control of an autonomous underwater vehicle (AUV). One application described here is a fuzzy logic six degree-of-freedom flight control system by the Ocean Voyager, an AUV currently under development. Heading, pitch, and depth are controlled simultaneously by three separate fuzzy logic controllers, each a function of setpoint error and error rate. An additional fuzzily constrained integrator compensates for frictional effects and setpoint error. The fuzzy controllers were tested and show good performance over a range of velocities. Another application described is a docking controller for the Ocean Voyager. This controller enables the AUV to dock with another underwater vehicle. Both moving and stationary targets are allowed. The fuzzy rule base recursively drives the vehicle toward intermediate fuzzy goals that become more precise as the final target is approached. The fuzzy goal approach does not rely on high accuracy maneuvers or waypoints. Docking proceeds as long as the AUV remains in a funnel of acceptable intermediate positions. Performance of the docking controller was tested by simulation. <<ETX>>
Fuzzy logic controller with dynamic rule set

The authors present a control methodology that enables a fuzzy controller to watch its output and if necessary change the inference rules by iterative steps. They present the simulation results obtained with a classic fuzzy logic controller model that uses the max-min composition for the inference rule system and calculates a singleton from the fuzzy set of the output by means of the center of gravity method of H. -J. Zimmerman (1990). Then they present a fuzzy logic controller model with a dynamic rule set (FCD). The results of the simulation carried out with the new FCD are discussed and compared with those for the classic controller. <<ETX>>
Analysis of Large-Scale Data from Human Activities on the Web

This work focuses on data mining and machine learning using large-scale datasets, with an emphasis on Web information, social computing, and on-line social networks. These datasets are becoming more numerous, and as the Web's reach grows, it is important to understand these datasets for two reasons. First, better understanding of the systems generating the data allows us to improve the systems. For example, by looking at where search queries come from, we can better select what results and advertisements to display. Second, an in-depth understanding of the data allows us to leverage it for a variety of purposes. For instance, by looking at the geographic sources of queries we can discover the reach of various ideas. In particular we will develop new algorithms to deal with these large datasets, answering the subtle and nuanced questions that require a huge amount of data and novel methodology. We will examine large social networks, and processes related to these networks such as group formation and network evolution. We will also look at data from web search, showing that it is a rich source of information which, when combined with IP address geolocation can tell us a great deal about the geographic extent of various terms. In addition to learning about these systems, we will also design algorithms for improving them. Through the use of server logs, we will show how changing content can be scheduled more optimally on web pages. Finally, we will examine some of the privacy implications of this style of research, showing a negative result which illustrates how careful we must be with our data.
