Segmentation of Liver Metastases Using a Level Set Method with Spiral-Scanning Technique and Supervised Fuzzy Pixel Classification (2008)

In this paper a specific method is presented to facilitate the semi-automatic segmentation of liver metastases in CT images. Accurate and reliable segmentation of tumors is e.g. essential for the follow-up of cancer treatment. The core of the algorithm is a level set function. The initialization is provided by a spiral-scanning technique based on dynamic programming. The level set evolves according to a speed image that is the result of a statistical pixel classification algorithm with supervised learning. This method is tested on CT images of the abdomen and compared with manual delineations of liver tumors.
Joint Optimization of Radio and Computational Resources for Multicell Mobile-Edge Computing (2015)

Migrating computational intensive tasks from mobile devices to more resourceful cloud servers is a promising technique to increase the computational capacity of mobile devices while saving their battery energy. In this paper, we consider an MIMO multicell system where multiple mobile users (MUs) ask for computation offloading to a common cloud server. We formulate the offloading problem as the joint optimization of the radio resources-the transmit precoding matrices of the MUs-and the computational resources-the CPU cycles/second assigned by the cloud to each MU-in order to minimize the overall users' energy consumption, while meeting latency constraints. The resulting optimization problem is nonconvex (in the objective function and constraints). Nevertheless, in the single-user case, we are able to compute the global optimal solution in closed form. In the more challenging multiuser scenario, we propose an iterative algorithm, based on a novel successive convex approximation technique, converging to a local optimal solution of the original nonconvex problem. We then show that the proposed algorithmic framework naturally leads to a distributed and parallel implementation across the radio access points, requiring only a limited coordination/signaling with the cloud. Numerical results show that the proposed schemes outperform disjoint optimization algorithms.
Fuzzy Controller for Wall-Climbing Microrobots (2004)

This paper presents a fuzzy control system that incorporates sensing, control and planning to improve the performance of the wall-climbing microrobots in unstructured environments. After introduction of the robot system, a task reference method is proposed which is based on a fuzzy multisensor data fusion scheme. The method provides a novel mechanism to efficiently integrate task scheduling, action planning and motion control in a unified framework. A robot gait generation method is described which switches the robot locomotion between different motion modes with the help of a finite state machine driven by sensory information. A fuzzy motion controller is designed to improve control performance and reduce power consumption by the suitable selection of fuzzy sets and inference methods, as well as the definition of corresponding membership functions and control rule bases. A fuzzy logic compensator is developed to compensate the gravitational effects according to different robot configurations and task situations. Experimental results prove the validity of the proposed methods.
Modified printed crescent patch antenna for Ultrawideband RFID (UWB-RFID) tag (2008)

In this paper we present the design of a modified crescent antenna for Ultrawideband (UWB) Radio Frequency identification (RFID) tag. Different studies to optimize the design of this antenna for the UWB-RFID system have been performed, particularly to overcome the main challenges such as minimizing the size of the antenna, improving its read range, and the effects of the metallic objects on the antenna performance. As a result of this study, the proposed antenna has a maximum read range between 5.4 m and 7.5 m with the ability to work in the UWB when the antenna is close to metallic objects.

Expression of biologically active human corticosteroid binding globulin by insect cells: acquisition of function requires glycosylation and transport. (1991)

Human corticosteroid binding globulin (hCBG) is a 50- to 55-kDa serum glycoprotein that binds cortisol and progesterone with high affinity. To map the steroid-binding domain and to investigate the folding pathways of hCBG, we have established an expression system based on infection of insect cells with a recombinant baculovirus encoding hCBG. Infected Spodoptera frugiperda (Sf9) cells secrete immunoreactive hCBG at high levels (16-24 pmol per 10(6) cells per 40 h), and the recombinant protein binds cortisol with an affinity and specificity equivalent to that of human serum-derived hCBG. Thus, this system has the potential to provide large amounts of wild-type and mutant hCBGs for physical-chemical analysis. Cotranslational asparagine-linked glycosylation is essential for acquisition of steroid-binding capability, as shown by the lack of cortisol-binding activity of unglycosylated hCBG secreted in the presence of tunicamycin. Golgi-associated oligosaccharide processing, however, is not required for activity, as demonstrated by the endoglycosidase H susceptibility of the fully active, secreted glycoprotein. Comparison of the steroid-binding properties of intracellular and secreted hCBG with that synthesized in vitro in the rabbit reticulocyte lysate system suggests that this protein undergoes a maturation process during transport through the secretory pathway. This system will be useful for identifying the molecular determinants of biological function in hCBG.

Current status and prospects of mfsfets and related devices (1997)

Abstract Novel applications of MFSFET (metal-ferroelectric-semiconductor field effect transistor) arrays to single-transistor-cell-type digital memories and to analog memories for storing the synaptic weight in artificial neural networks are first discussed. In these arrays, a ferroelectric film is sandwiched with Si stripes which are formed with npn regions on an insulating substrate, and metal stripes placed perpendicular to the Si stripes, and MFSFETs are formed at the cross points of both stripes. It is emphasized that the packing density of FETs is very high, since no via-hole exists in the array area. Then, recent progress of MFSFETs and related devices is reviewed, which includes PZT/Ir/IrO2/poly-Si/SiO2/Si, PZT/CeO2/Si, PZT/SrTiO3/Si,SrBi2Ta2O9/SiO2/Si,BaMgF4/Si, BaMgF4/Pt/SiO2/Si, and so on.
Metagility: Managing Agility for competitive advantage in new product development (2017)

Agile methodologies have become a popular and widely accepted method for managing software development. Since the inception of the Agile Manifesto over ten years ago, agile development techniques have superseded waterfall methods in many, if not most, software development organizations. Despite its apparent success, many companies have struggled with the adoption and implementation of agile, and exactly what level of adoption provides the most agility. Agility is commonly held in the literature to be constructed of elements external to a company or project but may in fact be composed of both external and internal elements. The exact relationship of the adoption of agile development techniques and their relationship to the actual agility of a business remain unclear. A primary contributor to this uncertainty is the somewhat amorphous definition of agile itself. In academic literature, the concept is still relatively young and loosely defined. In practice, organizations have largely opted for a hybrid approach to agile, mixing its concepts and methods with existing Stage Gate or waterfall methodologies. This has made the management of agile even more complex. Crucially, there is no definition or criterion available to determine the appropriate mix of agile and waterfall processes in an embedded software development context nor is there a method to determine the impact of one against the other. This paper examines the results of an interpretive case study as to how stakeholders manage both market and process agility in an embedded systems context via a hybrid agility implementation and product genesis to achieve “true agility”. Thus, we provide the notion of agile vorticity, as the point at which market and process agility collide to produce business momentum at a specific point of innovation within the agile business vortex.
Optical Emission Detection of Charged Particles after Selective Laser Ionization of Mercury Atoms in a Buffer Gas (1997)

A method for the optical detection of the resonance ionization signal of mercury atoms in a buffer gas is described that is based on the emission from buffer gas atoms that are collisionally excited by interactions with electrons in a strong electric field. The first observations of this phenomenon are reported here, along with comparisons between optical and electrical detection. Advantages of a pulsed electric field over a continuous field are described. A wide range of possible applications for this type of gas phase detector are suggested.

Robust Speech Hashing for Content Authentication (2009)

Robust hashing for multimedia authentication is an emerging research area. A novel key-dependent robust speech hashing based on speech production model is proposed in this letter. Robust hash is calculated based on linear spectrum frequencies (LSFs) which model the vocal tract. The correlation between LSFs is decoupled by discrete cosine transformation (DCT). A randomization scheme controlled by a secret key is applied in hash generation for random feature selection. The hash function is key-dependent and collision resistant. Meanwhile, it is highly robust to content preserving operations as well as having high accuracy of tampering localization.

Combating opiate dependence: a comparison among the available pharmacological options (2004)

Pharmacotherapies for heroin addiction may target opiate withdrawal symptoms, facilitate initiation of abstinence and/or reduce relapse to heroin use either by maintenance on an agonist or antagonist agent. Available agents include opioid agonists, partial opioid agonists, opioid antagonists and alpha 2 -agonists for use during managed withdrawal and long-term maintenance. Experimental approaches combine alpha 2 -agonists with naltrexone to reduce the time of opiate withdrawal and to accelerate the transition to abstinence. Recently, buprenorphine has been introduced in the US for office-based maintenance, with the hope of replicating the success of this treatment in Europe and Australia. Naloxone has been added to buprenorphine in order to reduce its potential diversion to intravenous use, whilst facilitating the expansion of treatment. Although comprehensive substance abuse treatment is not limited to pharmacotherapy, this review will focus on the rationale, indications and limitations of the range of existing medications for detoxification and relapse prevention treatments. The two major goals of pharmacotherapy are to relieve the severity of opiate withdrawal symptoms during the managed withdrawal of the opioid and to prevent relapse to heroin use either after abstinence initiation or after being stabilised on a long-acting opiate agonist, such as methadone.
Medical ultrasound image reconstruction using distributed compressive sampling (2013)

This paper investigates ultrasound (US) radiofrequency (RF) signal recovery using the distributed compressed sampling framework. The “correlation” between the RF signals forming a RF image is exploited by assuming that they have the same sparse support in the 1D Fourier transform, with different coefficient values. The method is evaluated using an experimental US image. The results obtained are shown to improve a previously proposed recovery method, where the correlation between RF signals was taken into account by assuming the 2D Fourier transform of the RF image sparse.
Empirical study on the role of aesthetic attributes of packaging on rural consumers in contest of packed restaurant food in dist. morena of Gwalior (M.P.) (2014)

Packaging was nicely defined as an extrinsic element of the product-an attribute that is related to the product but does not form part of the physical product itself in 1972 by Olson and Jacoby. Since then various definitions has evolved and many industrial practices has brought revolution in the packaging. Previously where packaging performed the function of just protection, preservation, now it is working as a marketing tool and promotion aid. Various attributes of packaging are identified which can attract the customers. In today's time of cut throat competition when industries are trying their hard to explore every possible aspect, one of the aspects that has come into picture is a feel which customer gets from the product i.e. aesthetic element. These elements in packaging can be color, size, design, material used, graphics and labeling. If marketer knows in advance which element of packaging has what kind of influence on consumers then they can plan their marketing plan accordingly. This research work focus on studying the relationship between various elements of packaging and consumer preferences for packed restaurant food in Morena dist. Near Gwalior of Madhya Pradesh.
Efficient parallel pipelinable VLSI architecture for finding the maximum binary number (1994)

The paper presents an architecture for finding the maximum among a group of k-bit binary numbers suitable for implementation in VLSI. This is done by first presenting a simple algorithm that is easily mapped into VLSI circuits with minimum complexity. A major objective of the design was to determine an efficient parallel pipelinable circuit for finding the maximum when all the bits are available in parallel. Such a unit could be used as an integral part of the Add-Compare-Select (ACS) unit of the Viterbi decoder or any other device that may require the use of a maximum finding circuit in its implementation. Another objective of the paper is to demonstrate that many of the asymptotically optimal algorithms for this problem may be inefficient for a practical VLSI implementation. This is because often these algorithms are written for an entirely different system model. The cost analysis and operational speed of the algorithm are addressed from the implemental point of view as opposed to the more traditional approach of analysing the cost and operational speed based on the number of computations and the number of processors irrespective of the degree of complexity of the units and other relevant routing issues.
Contactless Palmprint Identification Using Deeply Learned Residual Features (2020)

Contactless and online palmprint identification offers improved user convenience, hygiene, user-security and is highly desirable in a range of applications. This paper proposes an accurate and generalizable deep learning-based framework for the contactless palmprint identification. Our network is based on fully convolutional network that generates deeply learned residual features. We design a soft-shifted triplet loss function to more effectively learn discriminative palmprint features. Online palmprint identification also requires a contactless palm detector, which is adapted and trained from faster-R-CNN architecture, to detect palmprint region under varying backgrounds. Our reproducible experimental results on publicly available contactless palmprint databases suggest that the proposed framework consistently outperforms several classical and state-of-the-art palmprint recognition methods. More importantly, the model presented in this paper offers superior generalization capability, unlike other popular methods in the literature, as it does not essentially require database-specific parameter tuning, which is another key advantage over other methods in the literature.
Modulation of the apelin/APJ system in heart failure and atherosclerosis in man (2010)

We have detected changes in the apelin/APJ system in human diseased cardiac and vascular tissue. The decrease in receptor density in heart failure may limit the positive inotropic actions of apelin, contributing to contractile dysfunction. The contribution of the increased apelin levels in atherosclerotic coronary artery to disease progression remains to be determined. These data suggest a potential role for the apelin/APJ system in human cardiovascular disease.
Surprise-Based Intrinsic Motivation for Deep Reinforcement Learning (2017)

Exploration in complex domains is a key challenge in reinforcement learning, especially for tasks with very sparse rewards. Recent successes in deep reinforcement learning have been achieved mostly using simple heuristic exploration strategies such as $ε$-greedy action selection or Gaussian control noise, but there are many tasks where these methods are insufficient to make any learning progress. Here, we consider more complex heuristics: efficient and scalable exploration strategies that maximize a notion of an agent's surprise about its experiences via intrinsic motivation. We propose to learn a model of the MDP transition probabilities concurrently with the policy, and to form intrinsic rewards that approximate the KL-divergence of the true transition probabilities from the learned model. One of our approximations results in using surprisal as intrinsic motivation, while the other gives the $k$-step learning progress. We show that our incentives enable agents to succeed in a wide range of environments with high-dimensional state spaces and very sparse rewards, including continuous control tasks and games in the Atari RAM domain, outperforming several other heuristic exploration techniques.
Configuration management in an open architecture system power system control (1993)

The hardware and software operating environments for power system automation are described. Software portability and distributed databases are discussed. It is seen that in order to configure a system of computing elements that share information in an open architecture environment, a common system manager with respect to configuration, database and failover must reside at the system level, with elements residing at each logical node.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
GROα Is Highly Expressed in Adenocarcinoma of the Colon and Down-Regulates Fibulin-1 (2006)

Elevated expression of GROalpha is frequent in adenocarcinoma of the colon and is associated with down-regulation of the matrix protein fibulin-1 in experimental models and in clinical samples. GROalpha overexpression abrogates contact inhibition in cell culture models, whereas inhibition of GROalpha expression is associated with apoptosis. Importantly, coexpression of fibulin-1 with GROalpha abrogates key aspects of the transformed phenotype, including tumor formation in a murine xenograft model. Targeting GRO proteins may provide new opportunities for treatment of colon cancer.

Theory of Giant Magnetoresistance in Metallic Superlattices (1991)

The random exchange potential at the interfaces between magnetic and nonmagnetic layers is proposed to be an origin of the giant magnetoresistance in metallic superlattices. The material dependence of the potential is calculated for transition metal elements. An analysis using the Boltzmann equation shows that the theoretical results of the potential explain the giant magnetoresistance observed.
