Integrated single image super resolution based on sparse representation

This paper presents a new and efficient approach for single-image super-resolution based on sparse signal recovery. This approach uses a co-occurrence trained dictionary of image patches that obtained from a set of observed low- and high-resolution images. The linear combination of the dictionary patches can recover every patch, then each patch that used on the low-resolution image, can be recovered by the dictionary patches. Since the recovered patch is a linear combination of some patches, the noise of every patch, aggregated in the recovered patch, then we prefer a linear combination which is more sparse rather than other combinations. So the sparse representation of patches can filter the noise in the solution. Recently this approach has been used in single image super-resolution problem. These methods calculate the sparse representation of every patches separately and set it to the recovered high-resolution image. So the complexity of such methods are very high and for suitable solution the parameters of algorithm must be estimated, therefore, this process (recover all patch with an iterative algorithm and parameter estimation for each iterate) is very time consuming. This paper presents an integrated method for recovering a low-resolution image based on sparse representation of patches with one step and recover whole image together.
Failure Prediction in Hardware Systems

We analyze hardware sensor data to predict failures in a high-end computer server. Features are extracted using sensor windows and potential failure windows. We then train radial basis function networks on these features and achieve a 0.87 true positive rate and 0.10 false positive rate for predicting failures using a data set where failures and non-failures are equally likely. This shows that sensor data can be used to predict failures in hardware systems. We conclude by discussing the effects of costs, benefits, and prediction accuracy in the context of infrequent hardware failures.
Critical Behavior and Griffiths-McCoy Singularities in the Two-Dimensional Random Quantum Ising Ferromagnet

We study the quantum phase transition in the two-dimensional random Ising model in a transverse field by Monte Carlo simulations. We find results similar to those known analytically in one-dimension. At the critical point, the dynamical exponent is infinite and the typical correlation function decays with a stretched exponential dependence on distance. Away from the critical point there are Griffiths-McCoy singularities, characterized by a single, continuously varying exponent, z', which diverges at the critical point, as in one-dimension. Consequently, the zero temperature susceptibility diverges for a RANGE of parameters about the transition.
Deletion of Beta‐2‐Microglobulin Ameliorates Spinal Cord Lesion Load and Promotes Recovery of Brainstem NAA Levels in a Murine Model of Multiple Sclerosis

We used genetic deletion of β2‐microglobulin to study the influence of CD8+ T cells on spinal cord demyelination, remyelination, axonal loss and brainstem N‐acetyl aspartate levels during the acute and chronic phases of Theiler's murine encephalomyelitis virus (TMEV) infection. We used β2m−/− and β2m+/+ B10.Q mice (of H‐2q background) normally susceptible to TMEV‐induced demyelination. Over the disease course, β2m+/+ mice had increasing levels of demyelination and minimal late‐onset remyelination. In contrast, β2m−/− mice had steady levels of demyelination from 45–390 dpi and remyelination was extensive and more complete. Early in the disease, brainstem NAA levels drop in both strains, but accordingly with remyelination and axonal preservation, NAA recover in β2m−/− mice despite equivalent brainstem pathology. At 270 dpi, β2m+/+ mice had significantly fewer spinal cord axons than β2m−/− mice (up to 28% less). In addition, β2m+/+ mice lost axons of all calibers, whereas β2m−/− mice had a modest loss of only medium‐ and large‐caliber axons. This study further supports the hypothesis that CD8+ T cells are involved in demyelination, and axonal loss following Theiler's virus‐induced demyelination.
An effective hair removal algorithm for dermoscopy images

Dermoscopy is one of the major imaging modalities used in the diagnosis of pigmented skin lesions. Due to the difficulty and subjectivity of human interpretation, computerized image analysis techniques have become important tools in this research area. Hair removal from skin lesion images is one of the key problems for the precise segmentation and analysis of the skin lesions. In this study, we present a new scheme that automatically detects and removes hairs from dermoscopy images.
La mémoire procédurale : validité du concept et des méthodes d'évaluation

Proposee de longue date par les philosophes, la distinction memoire/ habitude correspond aujourd'hui aux concepts de memoire declarative et de memoire procedurale largement utilises en neuropsychologie. La place de la memoire procedurale dans les architectures theoriques de la memoire varie toutefois selon les auteurs. De plus, differentes epreuves sont proposees pour son evaluation mais une analyse cognitive de ces tâches fait largement defaut. Cet article montre en quoi les modeles d'apprentissage developpes en psychologie experimentale, en particulier par Anderson et Ackerman, peuvent se reveler pertinents pour mieux comprendre la memoire procedurale au plan theorique et mieux utiliser les epreuves qui sont censees l'evaluer. Nous illustrons notre demarche avec des epreuves procedurales couramment utilisees en neuropsychologie : le rotor test, la lecture en miroir et la tour de Hanoi.
Activity-dependent modulation of endocytosis by calmodulin at a large central synapse

Although Ca2+/calmodulin has been suggested to play a role during endocytosis, it remains unknown if binding of Ca2+ to calmodulin is essential for initiating endocytosis or if this interaction only has a modulatory effect on endocytosis. In this study, using time-resolved capacitance measurements at the rat calyx of Held synapse, the role of calmodulin in endocytosis was examined. Our results demonstrate that blocking calmodulin with an inhibitory peptide, which interfers with the binding of calmodulin to downstream targets, slowed the rate of endocytosis, but only when accompanied by high Ca2+ influx. In response to a short train of action potential-like stimulation, blocking calmodulin had no effect on endocytosis. Furthermore, we have identified conditions in which inhibition of calmodulin fails to affect the rate of endocytosis, but nevertheless retards recruitment of synaptic vesicles to the fast-releasing vesicle pool responsible for synchronous release. The results indicate that calmodulin facilitates endocytosis in an activity-dependent manner but is not mandatory for endocytosis, and suggest that calmodulin modulates an endocytotic intermediate process, which in turn affects synaptic vesicle recruitment and membrane fission.
The Elephant on the Couch: Side-Effects of Psychotherapy

Australian and New Zealand Journal of Psychiatry 2009; 43:787 794Although we take it as a given that many psy-chotherapies are efficacious, form a cornerstone ofmuch current practice, and are valued by manypatients, there is a dissonance in the way in whichphysical therapies and psychotherapies are consid-ered in terms of their cost benefit ratio. Any potentintervention has both the capacity to cure and toharm. For drug-based therapeutic trials, adverseevent monitoring is mandatory. By contrast, evalua-tion of psychotherapy has historically weighted the‘benefit’side of the equation. For example, is aparticular type of psychotherapy effective, is onepsychotherapy superior to another, or does psy-chotherapy benefit a particular condition? At first pass it might appear bizarre to questionwhether psychotherapy could be harmful or havesubstantive side-effects, with Nutt and Sharpe re-cently observing that there is an ‘assumption . thatas psychotherapy is only talking . no possible harmcould ensue’[1]. Certainly, patients rarely raise suchconcerns. By contrast, when a psychotropic drug isprescribed, most patients inquire about likely drugside-effects, while medico-legal injunctions oblige thepractitioner to detail and document substantive side-effects.Why the dissonance across those treatment mod-alities if we accept the principle that all effectivetreatments risk ad erse e ents? In arguing against thecommon assumption that adverse events of psy-chotherapy are slight, we offer several examples toargue that substantive costs can emerge from bothacts of omission and commission.ImpactofinappropriatepsychotherapyIf psychotherapy is provided as the only orprincipal therapy for a condition for which it is eitherinappropriate or ineffective, the patient may beexposed to a lengthy period of ongoing symptomsand disability an adverse outcome. As ‘acts ofomission’, such paradigm failures can be distinctive,with the Osheroff case being a well-documentedexample.As detailed by Shorter, Osheroff, a 42-year-oldphysician, was admitted to Chestnut Lodge withsymptoms of psychotic depression, received near-daily intensive psychotherapy and, over his 7 monthadmission, was denied medication despite his ownrequests [2]. Subsequently transferred to anotherhospital, he recovered after receiving psychotropicmedication, although his wife had left him, he hadlost his hospital accreditation and his medical partner‘ousted him from their joint practice’during hisextended hospitalization. Osheroff sued for malprac-tice on grounds that he should have received medica-tions of demonstrated efficacy rather than intensivepsychotherapy.ImpactofinappropriatepsychotherapistbehaviourPsychiatric patients are commonly highly troubledand vulnerable, whether personality based, and/or a
Privacy preserving research based on association rule algorithm

Privacy protection based on association rules aim is to find a data set of the original approach, making the mining of sensitive rules is to implement a data mining process is not to be found. To efficiently achieve privacy protection, this article combine the PPARM algorithm and IMBA algorithm, through the operation of sensitive items to do less, it will hidden sensitive rules more greater degree. It is making little effect on non-sensitive rules at the same time. That is making loss rate of the rules of the original database smaller. Theoretical and experimental results show that the algorithm is highly efficient, is a better method related to privacy protection.
Effect of plasma treated ITO substrate on inkjet printing of conductive ink

In this paper, we investigate the effect to inkjet printing by modifying the surface condition of the substrate by plasma treatment as a possible processing technique to improve the printability and repeatability of ink-jet printed conductive ink on ITO coated substrate, and to identify the relationship between process parameters and property. Oxygen plasma surface treatment has been found to increase the surface energy of ITO coated substrates used in OLED. Uniform dots and lines were the desired print pattern. Surface energy of the treated film was quantified through the measurements of contact angles using a commercial conductive ink PEDOT-PSS. In addition, surface roughness and morphology of the treated ITO films were investigated to identify their effect on printability of the polymer. As surface treatment is also known to affect electrical properties of ITO, sheet resistance was studied. Results show that oxygen plasma improved the print quality dramatically and by varying plasma conditions used. Experimental data also showed that surface energy changed with storage time after treatment. Contact angle increased from 13deg to 50deg after 48 hours.
Placement Optimization of Energy and Information Access Points in Wireless Powered Communication Networks

The applications of wireless power transfer technology to wireless communications can help build a wireless powered communication network (WPCN) with more reliable and sustainable power supply compared to the conventional battery-powered network. However, due to the fundamental differences in wireless information and power transmissions, many important aspects of conventional battery-powered wireless communication networks need to be redesigned for efficient operations of WPCNs. In this paper, we study the placement optimization of energy and information access points in WPCNs, where the wireless devices (WDs) harvest the radio frequency energy transferred by dedicated energy nodes (ENs) in the downlink, and use the harvested energy to transmit data to information access points (APs) in the uplink. In particular, we are interested in minimizing the network deployment cost with minimum number of ENs and APs by optimizing their locations, while satisfying the energy harvesting and communication performance requirements of the WDs. Specifically, we first study the minimum-cost placement problem when the ENs and APs are separately located, where an alternating optimization method is proposed to jointly optimize the locations of ENs and APs. Then, we study the placement optimization when each pair of EN and AP is colocated and integrated as a hybrid access point, and propose an efficient algorithm to solve this problem. Simulation results show that the proposed methods can effectively reduce the network deployment cost and yet guarantee the given performance requirements, which is a key consideration in future applications of WPCNs.
A Mathematica q-Analogue of Zeilberger's Algorithm Based on an Algebraically Motivated Approach to q-Hypergeometric Telescoping

A dynamometer for monitoring the tension in a pair of spaced, elongated members. A pen, actuated by a sensor means, measures the tension in the pair of spaced, elongated members, and places indicia upon a continuously moving chart. The indicia is related to the magnitude of the measured tension and is in the form of spaced-apart, individual curves or plots. Hence the pen contacts the chart for a first time interval; and thereafter, the pen is lifted from the chart for a second time interval so as to cyclically place the indicia upon the chart at successive intervals of time. More specifically, the dynamometer measures the tension in a rod string. The rod string is reciprocated by a pumpjack unit located above the ground and drives a downhole pump. The dynamometer therefore cyclically measures the pumping characteristics of the well at successive, predetermined intervals of time and provides a permanent record which can be stored and subsequently consulted in order to determine the characteristics of the entire pumping unit over a projected interval of time.
Dimensionality Reduction in Controlling Articulated Snake Robot for Endoscopy Under Dynamic Active Constraints

This paper presents a real-time control framework for a snake robot with hyper-kinematic redundancy under dynamic active constraints for minimally invasive surgery. A proximity query (PQ) formulation is proposed to compute the deviation of the robot motion from predefined anatomical constraints. The proposed method is generic and can be applied to any snake robot represented as a set of control vertices. The proposed PQ formulation is implemented on a graphic processing unit, allowing for fast updates over 1 kHz. We also demonstrate that the robot joint space can be characterized into lower dimensional space for smooth articulation. A novel motion parameterization scheme in polar coordinates is proposed to describe the transition of motion, thus allowing for direct manual control of the robot using standard interface devices with limited degrees of freedom. Under the proposed framework, the correct alignment between the visual and motor axes is ensured, and haptic guidance is provided to prevent excessive force applied to the tissue by the robot body. A resistance force is further incorporated to enhance smooth pursuit movement matched to the dynamic response and actuation limit of the robot. To demonstrate the practical value of the proposed platform with enhanced ergonomic control, detailed quantitative performance evaluation was conducted on a group of subjects performing simulated intraluminal and intracavity endoscopic tasks.
A new formalization of minimum classification error using a Parzen estimate of classification chance

Ina previous work, we showed that the minimum classification error (MCE) criterion function commonly used for discriminative design of pattern recognition systems is equivalent to a Parzen window based estimate of the theoretical classification risk. In this analysis, each training token is mapped to the center of a Parzen kernel in the domain of a suitably defined random variable; the kernels are then summed and integrated over the domain of incorrect classifications, yielding the risk estimate. Here, we deepen this approach by applying Parzen estimation at an earlier stage of the overall definition of classification risk. Specifically, the new analysis uses all incorrect categories, not just the single best incorrect category, in deriving a "correctness" function that is a simple multiple integral of a Parzen kernel over the region of correct classifications. The width of the Parzen kernel determines how many competing categories to use in optimizing the resulting overall risk estimate. This analysis uses the classic Parzen estimation method to support the notion that using multiple competing categories in discriminative training is a type of smoothing that enhances generalization to unseen data.
Output organization of intermediate cerebellum of the monkey.

1. The goal of this study was to investigate the motor organization of monkey nucleus interpositus (NI) and neighboring regions of the lateral nucleus (NL) by correlating discharge of single neurons with active movements. Neurons were surveyed during free-form movements as well as during operation of six devices that required movement about specific forelimb joints. The paradigm allowed us to test the hypothesis that discharge of individual cells relates to movements about individual joints. 2. One hundred sixty-two isolated nuclear neurons from two monkeys were studied. Eighty-three percent showed large increases in discharge (an average of 3 times resting rate for forelimb neurons) during movement of one body part, either forelimb, hindlimb, mouth/face, or eyes. 3. Anterior interpositus contains neurons related to hindlimb movement in anterior regions and neurons related to forelimb movement in posterior regions. A mouth/face-related area exists in the dorsal-posterior regions and is continuous with a mouth/face area in the dorsal regions of NL. Posterior interpositus (NIP) showed no clear separation between forelimb and hindlimb neurons: forelimb neurons were encountered throughout the nucleus, and hindlimb neurons were encountered in the medial-anterior two thirds. A distinct eye movement area exists in lateral, posterior, and ventral regions of NIP. This area borders regions of NL that also contain eye movement-related neurons. 4. Forelimb interpositus neurons discharged strongly during reach and grasp; discharge rates were recorded for 41 neurons during a stereotyped reach and the average depth of modulation was 149 imp/s. Nineteen neurons that modulated during device tracking were also tested during reaching, and the depth of modulation was much greater during reaching. 5. Fifty-nine forelimb neurons were tested with device tracking. Twenty-seven (46%) produced no audible modulation, regardless of the joint being exercised. The remaining 32 neurons modulated during movement on at least one device (mean depth of modulation = 84 imp/s). Comparison of discharge during use of different devices revealed no strong evidence for device-specific discharge. 6. Discharge modulations during device tracking were phasic, preceded movement, and, for a small number of cells, showed consistent parametric relations to duration, amplitude, and velocity of movement. 7. Despite a clear somatotopy within NI and NL, there is no finer mapping based on active movements about individual joints within forelimb regions. Discharge modulation depends on movements involving the whole limb. Progress in understanding the function of intermediate cerebellum depends on determining the variables required to elicit consistent and high modulation of neural discharge.

Immune Recognition of Fungal Polysaccharides

The incidence of fungal infections has dramatically increased in recent years, in large part due to increased use of immunosuppressive medications, as well as aggressive medical and surgical interventions that compromise natural skin and mucosal barriers. There are relatively few currently licensed antifungal drugs, and rising resistance to these agents has led to interest in the development of novel preventative and therapeutic strategies targeting these devastating infections. One approach to combat fungal infections is to augment the host immune response towards these organisms. The polysaccharide-rich cell wall is the initial point of contact between fungi and the host immune system, and therefore, represents an important target for immunotherapeutic approaches. This review highlights the advances made in our understanding of the mechanisms by which the immune system recognizes and interacts with exopolysaccharides produced by four of the most common fungal pathogens: Aspergillus fumigatus, Candida albicans, Cryptococcus neoformans, and Histoplasma capsulatum. Work to date suggests that inner cell wall polysaccharides that play an important structural role are the most conserved across diverse members of the fungal kingdom, and elicit the strongest innate immune responses. The immune system senses these carbohydrates through receptors, such as lectins and complement proteins. In contrast, a greater diversity of polysaccharides is found within the outer cell walls of pathogenic fungi. These glycans play an important role in immune evasion, and can even induce anti-inflammatory host responses. Further study of the complex interactions between the host immune system and the fungal polysaccharides will be necessary to develop more effective therapeutic strategies, as well as to explore the use of immunosuppressive polysaccharides as therapeutic agents to modulate inflammation.
Acquired Ondine's curse: case report.

UNLABELLED We report and discuss the case of a 55-year old man who presented a history of stroke as well as chronic obstructive pulmonary disease. When admitted into the emergency room, he was diagnosed with a vertebro-basilar syndrome. A brain MRI showed a hyperintense area in the lower right brainstem laterally within the medulla, which corresponds to the area of the pathways descending from the autonomic breathing control center. During hospitalization, the patient had several episodes of prolonged apnea, mainly when asleep, having often to be "reminded" to breath. A tracheostomy was then performed with the patient under mechanical ventilation. Treatment with medroxyprogesterone, fluoxetine and acetazolamide was also started. He was discharged after 64 days breathing environmental air with no apparent episodes of apnea. He returned to the emergency room in the following day with a clinical picture of aspiration bronchopneumonia, followed by septic shock and death. CONCLUSION the Ondine's curse is one of the posterior stroke's presentation characterized by loss of automatic breathing and for the unpredictability of clinical evolution and prognosis. Such a syndrome has rarely been reported in adults and the diagnostic criteria are not consensual in the reviewed literature. Thus any diagnostic confirmation should be flexible. There are many therapeutic symptomatic options in such cases, ranging from pharmacologic approach, use of bilevel positive airway pressure and implantation of diaphragmatic pacemaker.
