rGO/CuO/PEDOT nanocomposite formation, its characterisation and electrochemical performances for supercapacitors

Supercapacitor properties of rGO, CuO, PEDOT and rGO/CuO at [rGO]o/[CuO]o = 1:1; 1:1.5; 1:2 and rGO/CuO/PEDOT nanocomposite at [rGO]o/[CuO]o/[EDOT]o = 1:1:1; 1:1:3; 1:1:5 were investigated using chemical reduction of GO and in-situ polymerisation process. SEM-EDX, HRTEM, BET surface area analysis confirm the nanocomposite formations. Nanocomposite materials are also analysed through FTIR-ATR, Raman, TGA-DTA, GCD, CV and EIS. The highest specific capacitance of C sp = 156.7 F/g at 2 mV/s is determined as rGO/CuO/PEDOT at [rGO]o/[CuO]o/[EDOT]o = 1:1:5. In addition, two-electrode supercapacitor device for rGO/CuO/PEDOT at [rGO]o/[CuO]o/[EDOT]o = 1:1:5 are found to provide a maximum specific energy (E = 14.15 Wh/kg at 20 mA) and specific power (P = 24730 W/kg at 50 mA), electrical serial resistance (ESR = 13.33 Ω) with good capacity retention after 3000 cycles. An equivalent circuit model of LR1(CR2)(QR3) is proposed to interpret the EIS data. The supercapacitor performance of the rGO/CuO/PEDOT nanocomposite electrode indicates the synergistic effect of hybrid supercapacitors. GRAPHICAL ABSTRACT
Microstructure and Texture Inhomogeneity after Large Non-Monotonic Simple Shear Strains: Achievements of Tensile Properties

In this study, for the first time, the effect of large non-monotonic simple shear strains on the uniformity of the tensile properties of pure Cu specimens was studied and justified by means of microstructural and textural investigations. A process called simple shear extrusion, which consists of two forward and two reversed simple shear straining stages on two different slip planes, was designed in order to impose non-monotonic simple shear strains. Although the mechanism of grain refinement is continuous dynamic recrystallization, an exceptional microstructural behavior and texture were observed due to the complicated straining path results from two different slip planes and two pairs of shear directions on two different axes in a cycle of the process. The geometry of the process imposes a distribution of strain results in the inhomogeneous microstructure and texture throughout the plane perpendicular to the slip plane. Although it is expected that the yield strength in the periphery reaches that of the center by retardation, it never reaches that value, which results in the different deformation modes of the center and the periphery. The occurrence of shear reversal in each quarter of a cycle results in the elimination of some of the boundaries, an increase in the cell wall thickness, and a decrease in the Taylor factor. Change in the shear plane in each half of a cycle leads to the formation of cell boundaries in a different alignment. Since the direction of the shear and/or the shear plane change frequently in a cycle, the texture of a sample after multi-cycles of the process more closely resembles a random orientation.
A Study of Hand Back Skin Texture Patterns for Personal Identification and Gender Classification

Human hand back skin texture (HBST) is often consistent for a person and distinctive from person to person. In this paper, we study the HBST pattern recognition problem with applications to personal identification and gender classification. A specially designed system is developed to capture HBST images, and an HBST image database was established, which consists of 1,920 images from 80 persons (160 hands). An efficient texton learning based method is then presented to classify the HBST patterns. First, textons are learned in the space of filter bank responses from a set of training images using the l1 -minimization based sparse representation (SR) technique. Then, under the SR framework, we represent the feature vector at each pixel over the learned dictionary to construct a representation coefficient histogram. Finally, the coefficient histogram is used as skin texture feature for classification. Experiments on personal identification and gender classification are performed by using the established HBST database. The results show that HBST can be used to assist human identification and gender classification.
A Highly Organized Structure Mediating Nuclear Localization of a Myb2 Transcription Factor in the Protozoan Parasite Trichomonas vaginalis

ABSTRACT Nuclear proteins usually contain specific peptide sequences, referred to as nuclear localization signals (NLSs), for nuclear import. These signals remain unexplored in the protozoan pathogen, Trichomonas vaginalis. The nuclear import of a Myb2 transcription factor was studied here using immunodetection of a hemagglutinin-tagged Myb2 overexpressed in the parasite. The tagged Myb2 was localized to the nucleus as punctate signals. With mutations of its polybasic sequences, 48KKQK51 and 61KR62, Myb2 was localized to the nucleus, but the signal was diffusive. When fused to a C-terminal non-nuclear protein, the Myb2 sequence spanning amino acid (aa) residues 48 to 143, which is embedded within the R2R3 DNA-binding domain (aa 40 to 156), was essential and sufficient for efficient nuclear import of a bacterial tetracycline repressor (TetR), and yet the transport efficiency was reduced with an additional fusion of a firefly luciferase to TetR, while classical NLSs from the simian virus 40 T-antigen had no function in this assay system. Myb2 nuclear import and DNA-binding activity were substantially perturbed with mutation of a conserved isoleucine (I74) in helix 2 to proline that altered secondary structure and ternary folding of the R2R3 domain. Disruption of DNA-binding activity alone by point mutation of a lysine residue, K51, preceding the structural domain had little effect on Myb2 nuclear localization, suggesting that nuclear translocation of Myb2, which requires an ordered structural domain, is independent of its DNA binding activity. These findings provide useful information for testing whether myriad Mybs in the parasite use a common module to regulate nuclear import.
Electrospun Nanofibers in Tissue Engineering

The field of tissue engineering and regenerative medicine is a fast growing scientific field. Many diseases and injuries that result in the loss of organ or tissue functions currently lack treatments which restore those functions and the patient to a desirable quality of life. Many current treatments could greatly benefit from incorporation of bioengineered organs and tissues, and investigation into this field shows great promise for modern medicine. Tissue engineering hypothesizes that by incorporating appropriate cells in the context of a threedimensional scaffold and then implanting the cell-scaffold construct into an injury or defect, that the cells and scaffold will provide both active and passive healing properties. Various scaffolding systems exist and are generally made from natural and/or synthetic polymers. Scaffolds can be fabricated by many methods including solvent casting and particulate leaching, melt molding, rapid prototyping, phase separation, and many others (Yang et al., 2001). Of particular interest to the subject of nanofibers is electrospinning, which has seen widespread use in the field of tissue engineering due to the ease of use, scalability, adaptability, and capacity to form fibers on both the micro and nano scale (Sill & von Recum, 2008). In constructing scaffolds for tissue engineering it is ideal to provide cells with an environment which closely resembles their native extracellular matrix (ECM). The spinning of nanofibers allows for a connected and porous scaffold which can mimic the ECM of many tissue types structurally, chemically, and mechanically. The ECM is a largely proteinaceous cellular environment that varies greatly between tissue types. In most tissue types the ECM is composed of a highly interconnected network of proteins such as collagen and elastin, and proteoglycans such as perlecan (Lodish et al., 2008). These molecules link together to form a functional environment in which cells live, move, receive and transmit signals, and which provides structural support to the cells, tissue, and organ as a whole. The composition of molecules in the ECM has a strong influence on the structural properties of the tissue which it helps compose. For example, in tissues which must stretch and bend, such as the muscle of the heart, elastin is a necessary ECM component which lends elasticity to the tissue when found in sufficient quantities (Lodish et al., 2008). Similar examples may be found in all tissue types, exemplifying the common theme of structure supplying function found throughout biology. The ECM is approximately nano scale and fibrous, though the fiber orientation depends on the tissue type. For example, dermis has randomly oriented fibers so as to provide structural support when stretched in different directions, while ligaments have a highly directional ECM so as to provide support in the direction of stress.
Effect of Formulation Factors on In Vitro Corneal Permeation of Fluconazole Through Excised Sheep Cornea

Fungal keratitis is a corneal inflammation with blurred vision and painful eye, which can be treated with fluconazole eye drops. The aim of the study was to find out effect of various formulation parameters on in vitro corneal permeation of fluconazole eye drops. The corneal permeation studies were conducted using freshly excised sheep cornea, mounted between donor and receptor chambers of an all glass modified Frenz diffusion cell, containing 11 ml of ringer bicarbonate (pH 7.4, 34 o ±1 o C). At the end of the experiment, each cornea (freed from sclera) was weighed, soaked in 1 ml. methanol, dried overnight at 90 °C and reweighed. From the difference in weights corneal hydration was calculated. Formulation of pH 6 and concentration 2% containing phosphate buffer and mannitol as tonicity modifier, butyl alcohol as preservative, HPMC as viscosity modifier shows maximum permeation. The effects of different formulation parameters on corneal permeation were characterized and the model formulation of fluconazole was developed on the basis of the result. Even though, the marketed formulation (Zocon) comprised of 0.3% w/v of fluconazole and our model formulation contained only 0.2% w/v of fluconazole, the amount of fluconazole permeated from model formulation was much greater than the marketed formulation.
The time-triggered model of computation

The Time-Triggered (TT) model of computation is a model for the representation and analysis of the design of large hard real time systems. Central to this model is the concept of temporal accuracy of real time information. The TT model consists of four building blocks, interfaces that contain temporally accurate data, a communication subsystem that connects interfaces, a host computer that reads input data from interfaces and writes output data to interfaces and a transducer that transforms the information representation in the environment into the digital form of the interface and vice versa. These four building blocks can be used recursively to describe arbitrary large hard real time systems. The TT model separates cleanly the design of the interaction pattern among components from the design of the components themselves. It thus supports a compositional design. In the final section the TT model is compared to the client server model.
Time-Space Lower Bounds for Directed st-Connectivity on Graph Automata Models

Directed st-connectivity is the problem of detecting whether there is a path from a distinguished vertex s to a distinguished vertex t in a directed graph. We prove time--space lower bounds of $ST = \Omega({n^{2} \log n \over \log (n \log n/S)})$ and $S^{1 \over 2}T = \Omega(m (n \log n)^{1 \over 2})$ for directed st-connectivity on Cook and Rackoff's jumping automaton for graphs (JAG) model [SIAM J. Comput. , 9(1980), pp. 636--652], where n is the number of vertices and m the number of edges in the input graph, S is the space, and T the time used by the JAG. These lower bounds are simple and elegant, they approach the known upper bound of T = O(m) when S approaches $\Theta(n \log n)$, and they are the first time--space tradeoffs for JAGs with an unrestricted number of jumping pebbles.
Impact of antiphosholipid biology in maternal Down syndrome screening

Women with antiphospholipid (aPL) biology present obstetric complications. The α‐fetoprotein (AFP) serum levels of these patients are higher than in general population. Because AFP is involved in the calculation of the risk of trisomy 21 (T21), we studied the effect of AFP variations in the presence of aPL during T21 screening.
The ipc/HYDRA tool chain for the analysis of PEPA models

PEPA is a popular stochastic process algebra and a powerful formalism for describing performance models of communication and computer systems. We augment the current state-of-the-art in the analysis of PEPA models by presenting a tool set that cannot only perform steady-state and transient analysis, but also response time analysis. Response time densities and quantiles are important performance metrics which are used to specify service level agreements (SLAs) and benchmarks. HYDRA is a tool specialising in response time analysis of large Markov systems based on stochastic Petri nets. By using the imperial PEPA compiler (ipc), we can generate a HYDRA model from a PEPA model and obtain steady-state, transient and response time measures based on the original PEPA description.
Statistical Parsing Algorithms for Lexi-calized Tree Adjoining Grammars

STATISTICAL PARSING ALGORITHMS FOR LEXICALIZED TREE ADJOINING GRAMMARS Anoop Sarkar Supervisor: Professor Aravind Joshi The goal of this dissertation is two-fold: to develop the theory of probabilistic Tree Adjoining Grammars (TAGs) and to present some practical results in the form of e cient parsing and estimation algorithms for probabilistic TAGs.

The practical results in parsing and estimation of probabilistic TAGs are developed with a view towards an increasingly unsupervised approach to the training of statistical parsers and language models. In particular, this proposal contains the following results: An algorithm for determining de ciency in a generative model for probabilistic TAGs. A novel chart based head-corner parsing algorithm for probabilistic TAGs. A probability model for statistical parsing and a co-training method for training this parser which combines labeled and unlabeled data. An algorithm for computing pre x probabilities which can be used to predict the word most likely to occur after an initial substring of the input.
Recently emerging advancements in halloysite nanotubes polymer nanocomposites

ABSTRACT Recently, as a result of their superior thermal stability, high aspect ratios, biocompatibility, mechanical properties, and ease of availability, halloysite nanotubes (HNTs), naturally sourced nanomaterials exhibiting one dimensionality and hollow tubular nanostructures have attracted global interests due to their potential utilization in polymer nanocomposites. Polymer nanocomposites (PNCs) filled with HNTs exhibits highly improved toughness, tensile and ﬂexural strength, and elastic moduli. HNT-polymer nanocomposites (HNT-PNCs) have also demonstrated enhanced thermal stability, fire hindrance and peculiar crystallization attributes. As a result of their tubular microstructure and biocompatibility, HNT-PNCs have revealed excellent drug encapsulating and releasing affinities, giving them significant utilization as drug purveyors, in tissue engineering and scaffolding. In present elucidation, novel recently emerging trends in fabrication, functionalization and application of HNT-PNCs in medicine, pharmaceuticals, aerospace and automobile industries are presented. Past, current and future market prospects of HNT-PNCs are also presented. Graphical Abstract
Question Answering Experiments and Resources

MIT CSAIL’s entries for the TREC Question Answering track (Voorhees, 2006) explored the effects of new document retrieval and duplicate removal strategies for ‘list’ and ‘other’ questions, established a baseline for other systems in the interactive task, and focused on question analysis and paraphrasing, rather than incorporation of external knowledge, in the factoid task. Many of the individual subsystems are largely unchanged from last year. We found that document retrieval strategy has an influence on performance in the different kinds of tasks later in the pipeline. Our other changes from last year did not immediately yield clear lessons. We present a question analysis data set and interannotator agreement indicators for the ciQA task that we hope will spur further evaluation.
Daydream Believer: Rumination, Self-Reflection and the Temporal Focus of Mind Wandering Content

Current research into mind-wandering is beginning to acknowledge that this process is one of heterogeneity. Following on from previous findings highlighting the role of self-focus during mind wandering, the present study aimed to examine individual differences in rumination and self-reflection and the impact such styles of self-focus may have on mind-wandering experiences. Thirty-three participants were required to complete the Sustained Attention Response Task (SART), aimed at inducing mind-wandering episodes, whilst also probing the content of thought in terms of temporal focus. Self-report questionnaires were also administered after the SART to measure dispositional differences in style and beliefs regarding mind-wandering and assessments of individual differences in rumination and self-reflection. Those individuals with reflective self-focus showed a strong positive association with positive and constructive thoughts. Critically, ruminative self-focus was positively associated with a tendency for the mind to wander towards anguished fantasies, failures and aggression, but it was also positively associated with positive and constructive thoughts. Furthermore, while dispositional differences in self-focus showed no relationship with the temporal perspective of thoughts when probed during a cognitive task, performance on the task itself was related to whether participants were thinking about the past, present or future during that activity. Such findings are discussed in line with previous research, and provide a further step towards accounting for the heterogeneous nature of mind-wandering.

Resilient Design for Process and Runtime Variations

Computing systems, ranging from high performance computers such as servers to embedded systems such as smart phones and handheld medical devices, have been working their way into many aspects of daily life. As a result, semiconductor industry has encountered persistent pressure to improve chip performance and functionality while decreasing cost and time to market. Down-scaling of the transistor feature size, increasing operating frequencies, and increasing transistor count per chip are the most important drivers to allow for high performance. However, these drivers also pose a major challenge due to parameter variations at manufacturing and runtime, induced by imperfections in the manufacturing process and variations in workloads and environment. Parameter variations are considered as the dominant source of lifetime and performance limiters of circuits, increasing the chip failure rate. Nevertheless, the circuits have to be designed to maintain a specific level of performance and power consumption over a specified lifetime in the presence of parameter variations. The main objective of this thesis is to tackle the impact of parameter variations in order to improve the chip performance and extend its lifetime. To achieve this goal, it is required to: 1) understand and analyze parameter variations and consider their interdependency, 2) develop fast and accurate reliability evaluation platforms to incorporate the combined effects of variations and transistor aging into Very Large Scale Integration (VLSI) design process, 3) develop techniques to track and monitor lifetime-delay-power changes of the chip during in-field operation, and 4) develop design-time and runtime adaptive techniques for alleviating the effects of variations to guarantee the resilience of the chip throughout its lifetime This thesis presents a set of unified analysis and design techniques for resilient systems in the presence of combined effects of parameter variations. First, a holistic agingand variation-aware timing analysis framework is de-
