Functionalized graphene oxide for clinical glucose biosensing in urine and serum samples

A novel clinical glucose biosensor fabricated using functionalized metalloid-polymer (silver-silica coated with polyethylene glycol) hybrid nanoparticles on the surface of a graphene oxide nanosheet is reported. The cyclic voltammetric response of glucose oxidase modification on the surface of a functionalized graphene oxide electrode showed a surface-confined reaction and an effective redox potential near zero volts, with a wide linearity of 0.1–20 mM and a sensitivity of 7.66 μA mM−1 cm−2. The functionalized graphene oxide electrode showed a better electrocatalytic response toward oxidation of H2O2 and reduction of oxygen. The practical applicability of the functionalized graphene oxide electrode was demonstrated by measuring the peak current against multiple urine and serum samples from diabetic patients. This new hybrid nanoarchitecture combining a three-dimensional metalloid-polymer hybrid and two-dimensional graphene oxide provided a thin solid laminate on the electrode surface. The easy fabrication process and retention of bioactive immobilized enzymes on the functionalized graphene oxide electrode could potentially be extended to detection of other biomolecules, and have broad applications in electrochemical biosensing.

Feelings about the self and body in eating disturbances: The role of internalized shame, self-esteem, externalized self-perceptions, and body shame

Abstract Objective: To investigate the roles of feelings of low self-worth (internalized shame and low self-esteem), externalized self-perceptions (self-objectification and body surveillance), body shame, and depressive symptoms in directly and indirectly explaining variance in eating disorder (ED) pathology across two studies. Study 1: In 403 women, internalized shame and self-esteem were found to each be independently associated with ED pathology, over and above one another, depressive symptoms, age and BMI. Further, body shame fully mediated the relationships between ED pathology and internalized shame and self-esteem, controlling for one another, depressive symptoms, age and BMI. Study 2: In a different sample of 548 women, Structural Equation Modeling (SEM) revealed that a path model in which internalized shame predicts ED pathology both directly and indirectly via self-objectification, body surveillance, body shame, and depressive symptoms demonstrated very good fit for the data and explained 68% of the variance in ED pathology. General conclusions: Results support an understanding of EDs as disorders of self, in which negative feelings about the self (internalized shame and low self-esteem) are displaced onto the body (in the form of externalized self-perceptions and body shame) and are associated with increases in depressive symptoms and ED pathology, both directly and indirectly.
A colour face image database for benchmarking of automatic face detection algorithms

With increasing research in the area of face segmentation, new methods for detecting human faces automatically are being developed. However, less attention is being paid to the development of a standard face image database to evaluate these new algorithms. This paper recognizes the need for a colour face image database and creates such a database for direct benchmarking of automatic face detection algorithms. The database has two parts. Part one contains colour pictures of faces having a high degree of variability in scale, location, orientation, pose, facial expression and lighting conditions, while part two has manually segmented results for each of the images in part one of the database. This allows direct comparison of algorithms. These images are acquired from a wide variety of sources such as digital cameras, pictures scanned in from a photo-scanner and the World Wide Web. The database is intended for distribution to researchers. Details of the face database such as the development process and file information along with a common criterion for performance evaluation measures is also discussed in this paper.
Signal filtering in PID control

The major input signals entering the PID controller are; the setpoint, the process output, and measurable load disturbances. By feeding these signals through suitable filters, the properties of the feedback loop can be improved significantly. This presentation will treat setpoint handling, feedforward from load disturbances, TITO (two input two output) control, noise filtering, and process dynamics compensation. An industrial case from the steel industry is also discussed.
Conversing about aging and practice

ABSTRACT Using four open-ended questions, individual conversations were conducted with 20 professionals from 10 fields of practice in aging. Professionals were over 60 years of age, had worked in the field at least 10 years, and personally considered themselves elders. This project found that they were aware of their personal aging process, were knowledgeable about resources, had considered their values, beliefs, and interests, and had developed an “aging plan” that would optimize a meaningful and enjoyable quality of life. They generally viewed themselves positively, had a strong sense of identity, accepted the changes that come with aging, and maintained an active and engaged lifestyle. They understood the commonalities of aging, but also respected and valued the uniqueness of each individual’s experiences. Aging had significantly affected their professional practice as well, primarily by increasing empathy, sensitivity, understanding, and patience, as well as through greater awareness and special attention to meaningful communication with clients and patients. Their personal aging awareness had a generally positive effect on professional practice. Practitioners’ thoughts and experiences with their own aging can both serve as a model for the general public and be utilized to programs to assist seniors in remaining vital members of society
Map Matching Scheme for Position Estimation of Planetary Explorer in Natural Terrain

This paper describes a position identification method to precisely estimate the relative movement onboard of an autonomous explorer in such natural terrain as Moon or Mars. This paper proposes a new map matching scheme that registers the visual information of consecutive robot positions and expresses the robot displacement in a common coordinate system. Local elevation maps of the environment are therefore retrieved from the 3D perception of a stereo camera. The proposed scheme consists of three main steps: feature point extraction from map data, matching of features points using triangle configurations and a voting procedure, and direct calculation of the robot displacement in six degrees of freedom using quaternions. The effectiveness of the proposed method is confirmed by computer simulations with synthetic terrain and experiments with stereo perception.
A new coupled inductor multilevel inverter based on switched DC sources

A new multilevel inverter is proposed in this paper. In the proposed topology, the output current is increased (in comparison with the switches current) using the coupled-inductors at the output stage of the inverter. It consists of two parts; one part includes the floating dc voltage sources connected by the power electronic switches in a special arrangement and the other part includes two power electronic switches. These two parts are connected to each other by a coupled-inductor. Most of the switches in the proposed topology have low current and voltage ratings making it suitable for high-current and also high-voltage applications. Also, the number of power components is reduced in the proposed topology. The 9-level case of the proposed topology has been investigated in details and its pulse-width modulation (PWM) based control is presented. The simulation results of the 9-level inverter are presented to verify its performance and control.
Maximizing spectral utilization in WDM systems by microwave domain filtering of tandem single sidebands

We present an optical tandem single-sideband receiver that enables the detection of signals having different information in the two sidebands of the same optical carrier. The technique relies on the use of a dual-electrode Mach-Zehnder modulator and achieves heterodyne detection without the use of an optical local oscillator. Sharp filtering requirements are met in the electrical domain, eliminating the need for wasteful guardbands.
Pointed and copointed Hopf algebras as cocycle deformations

We show that all finite dimensional pointed Hopf algebras with the same diagram in the classification scheme of Andruskiewitsch and Schneider are cocycle deformations of each other. This is done by giving first a suitable characterization of such Hopf algebras, which allows for the application of a result of Masuoka about Morita-Takeuchi equivalence and of Schauenburg about Hopf Galois extensions. The "infinitesimal" part of the deforming cocycle and of the deformation determine the deformed multiplication and can be described explicitly in terms of Hochschild cohomology. Applications to, and results for copointed Hopf algebras are also considered.
The morphosyntax of the periphrastic future under negation in Cypriot Greek

In Cypriot Greek, the negated future is marked by the element tha, which appears instead of the expected present tense copula and a selected subordinating element. This paper documents the distribution of this item for the first time, and presents an analysis in Distributed Morphology that analyzes tha as a portmanteau morpheme realizing two heads in the context of negation. This analysis requires that spans (or targets of Fusion) can include a verb and the head of its C complement.
Kinodynamic Motion Planning: A Novel Type Of Nonlinear, Passive Damping Forces And Advantages

T his article extends the capabilities of the harmonic potential field (HPF) approach to planning to cover both the kinematic and dynamic aspects of a robot's motion. The suggested approach converts the gradient guidance field from a harmonic potential to a control signal by augmenting it with a novel type of damping forces called nonlinear, anisotropic, damping forces (NADFs). The combination of the two provides a signal that can both guide a robot and effectively manage its dynamics. The kinodynamic planning signal inherits the guidance capabilities of the harmonic gradient field. It can also be easily configured to efficiently suppress the inertia-induced transients in the robot's trajectory without compromising the speed of operation. The approach works with dissipative systems as well as systems acted on by external forces without needing the full knowledge of the system's dynamics. Theoretical developments and simulation results are provided in this article. The HPF approach to planning is emerging as a powerful paradigm for the guidance of autonomous agents. Since it was suggested in the mid-late 1980s [1], [2], the approach is continuously being developed to meet the stringent requirements operation in a real-life environment imposes on an agent. Until now, the approach has amassed many attractive properties crucial for enhancing goal reachability. The approach is provably correct, driving the agent to a successful conclusion if the task is manageable and providing an indication if the task is intractable. It can be used to guide the motion of an arbitrarily shaped agent in an unknown environment regardless of its geometry or topology, relying only on the sensory data acquired online by the agent's finite-range sensors. The method can also impose a variety of constraints on the agent's trajectory such as regional avoidance and directional constraints [3]–[8]. Harmonic functions are also Morse functions and a general form of the navigation functions suggested in [13] (see ''Navigation Functions''). A planner may be defined as an intelligent, purposive, context sensitive controller that can instruct an agent on how to deploy its motion actuators (i.e., generate a control signal) so that a target state may be reached in a constrained manner. Traditionally, a planning task is distributed at two stages: a high-level control (HLC) and a low-level control (LLC). The HLC stage receives data about the environment, the target of the agent, and constraints on its behavior. It then simultaneously processes these data to generate a reference plan or …
On Extending the Primary-copy Database Replication Paradigm

In database replication, primary-copy systems sort out easily the problem of keeping replicate data consistent by allowing only updates at the primary copy. While this kind of systems are very efficient with workloads dominated by read-only transactions, the update-everywhere approach is more suitable for heavy update loads. However, it behaves worse when dealing with workloads dominated by read-only transactions. We propose a new database replication paradigm, halfway between primary-copy and update-everywhere approaches, which permits improving system performance by adapting its configuration to the workload, by means of a deterministic database replication protocol which ensures that broadcast writesets are always going to be committed.
Monosyllable Isolated Word Recognition for Tamil language using Continuous Density Hidden Markov Model

Developments in the communication technology have influenced the research trends to focus on speech technology. An Automatic Speech Recognition (ASR) may be classified into two based on the basic acoustic unit it can handle and they are word based or sub word based like phoneme, syllable, morpheme, senone. Hidden Markov Model (HMM) is the popular statistical model used in ASR and it assigns probability to the sequence of acoustic features extracted from the speech signal. Continuous Density Hidden Markov Models (CD-HMM) in which the observations are continuous and they are the important component of modern ASR Systems. Mel Frequency Cepstral Coefficients (MFCC) of the spoken words are used as training speech vectors to create CD-HMM which aid in recognition. This paper outlines the word based Isolated Word Recognition (IWR) for monosyllable words of Tamil language using CD-HMM and compares the result.
Data Envelopment Analysis of Relative Efficiencies of Public and Private Institutions of Higher Learning

There has been considerable public debate surrounding the efficiency of higher education in the United States. Using Data Envelopment Analysis, we look at the efficiency of a majority of the institutions of higher learning in the United States. Using two different approaches, we find some evidence that private institutions of higher learning are more efficient than public ones. In particular, masters and bachelors-granting institutions with unrestricted revenue greater than 85% are more efficient than those with less than 85%. Public institutions tend to have more restricted funding, suggesting that their stakeholders constrain them from operating on the frontier.
Speech recognition over bluetooth wireless channels

This paper studies the effect of Bluetooth wireless channels on distributed speech recognition. An approach for implementing speech recognition over Bluetooth is described. We simulate a Bluetooth environment and then incorporate its performance, in the form of packet loss ratio, into the speech recognition system. We show how intelligent framing of speech feature vectors, extracted by a fixed-point arithmetic front-end, together with an interpolation technique for lost vectors, can lead to a 50.48% relative improvement in recognition accuracy. This is achieved at a distance of 10 meters, around the maximum operating distance between a Bluetooth transmitter and a Bluetooth receiver.
Task-level timing models for guaranteed performance in multiprocessor networks-on-chip

We consider a dynamic application running on a multiprocessor network-on-chip as a set of independent jobs, each job possibly running on multiple processors. To provide guaranteed quality and performance, the scheduling of jobs, jobs themselves and the hardware must be amenable to timing analysis. For a certain class of applications and multiprocessor architectures, we propose exact timing models that effectively co-model both the computation and communication of a job. The models are based on interprocessor communication (IPC) graphs [4]. Our main contribution is a precise model of network-on-chip communication, including buffer models. We use a JPEG-decoder job as an example to demonstrate that our models can be used in practice to derive upper bounds on the job execution time and to reason about optimal buffer sizes.
A TRPA1-dependent mechanism for the pungent sensation of weak acids

Acetic acid produces an irritating sensation that can be attributed to activation of nociceptors within the trigeminal ganglion that innervate the nasal or oral cavities. These sensory neurons sense a diverse array of noxious agents in the environment, allowing animals to actively avoid tissue damage. Although receptor mechanisms have been identified for many noxious chemicals, the mechanisms by which animals detect weak acids, such as acetic acid, are less well understood. Weak acids are only partially dissociated at neutral pH and, as such, some can cross the cell membrane, acidifying the cell cytosol. The nociceptor ion channel TRPA1 is activated by CO2, through gating of the channel by intracellular protons, making it a candidate to more generally mediate sensory responses to weak acids. To test this possibility, we measured responses to weak acids from heterologously expressed TRPA1 channels and trigeminal neurons with patch clamp recording and Ca2+ microfluorometry. Our results show that heterologously expressed TRPA1 currents can be induced by a series of weak organic acids, including acetic, propionic, formic, and lactic acid, but not by strong acids. Notably, the degree of channel activation was predicted by the degree of intracellular acidification produced by each acid, suggesting that intracellular protons are the proximate stimulus that gates the channel. Responses to weak acids produced a Ca2+-independent inactivation that precluded further activation by weak acids or reactive chemicals, whereas preactivation by reactive electrophiles sensitized TRPA1 channels to weak acids. Importantly, responses of trigeminal neurons to weak acids were highly overrepresented in the subpopulation of TRPA1-expressing neurons and were severely reduced in neurons from TRPA1 knockout mice. We conclude that TRPA1 is a general sensor for weak acids that produce intracellular acidification and suggest that it functions within the pain pathway to mediate sensitivity to cellular acidosis.
Effect of dynamical spectral weight redistribution on effective interactions in time-resolved spectroscopy

The redistribution of electrons in an ultrafast pump-probe experiment causes significant changes to the spectral distribution of the retarded interaction between electrons and bosonic modes. We study the influence of these changes on pump-probe photoemission spectroscopy for a model electron-phonon coupled system using the nonequilibrium Keldysh formalism. We show that spectral rearrangement due to the driving field preserves an overall sum rule for the electronic self-energy, but modifies the effective electron-phonon scattering as a function of energy. Experimentally, this pump-modified scattering can be tracked by analyzing the fluence or excitation energy dependence of population decay rates and transient changes in dispersion kinks.
The dynamics of collective sorting robot-like ants and ant-like robots

A distributed sorting algorithm, inspired by how ant colonies sort their brood. is presented for use by robot teams. The robots move randomly, do not communicate. have no hierarchical organisation, have no global representation. can only perceive objects just in front of them, but can distinguish between objects of two or more types with a certain degree of error. The probability that they pick up or put down an object is modulated as a function of how many of the same objects they have met in the recent past This generates a positive feed-back that is sufficient to coordinate the robots' activity, resulting in their sorting the objects into common clusters. While less efficient than a hierarchically controlled sorting, this decentralised organisation offers the advantages of simplicity, flexibility and robustness.
