Left Sided Ptosis in Patient with Medical History of Migraine and Allergy: The Case Report of Probable Ophthalmoplegic Migraine

Ophtalmoplegic migraine is a very sophisticated condition characterized by ophtalmoplegia or ophtalmoparesis accompanied by ipsilateral headache. Previously considered as a type of migraine with cranial nerves palsy and finally has being interpreted as a recurrent painful ophthalmoplegic neuropathy.  We present the case of a female patient with medical history of migraine that developed left sided ptosis. We suppose that there may have been an allergic mechanism involved. We have not found any other reasonable explanation for the cause of the symptoms. Moreover, the patient exhibited acute hives accompanied by Quincke's edema. We suspect that it could be the expression of the cross reaction between allergens of orange and gadolinium based magnetic resonance contrast. After the treatment with steroids the symptoms diminished. Full range of diagnostic procedures has been applied to exclude secondary causes of the symptoms.  Clinicians are obliged to perform the wide differential diagnosis of the headache accompanied by oculomotor dysfunction. We suggest that in the cases of no objective cause of the symptoms, we should take into account ophtalmoplegic migraine. That might lead to more targeted diagnostic procedures and better therapy.
A framework for multi robot pose graph SLAM
Venue: 2016 IEEE International Conference on Real time Computing and Robotics (RCAR)

We introduce a software framework for real time multi robot collaborative SLAM. Rather than building a complete SLAM system, our framework is designed to enable collaborative mapping for existing (single robot) SLAM systems in a convenient fashion. The framework aggregates local pose graphs obtained from its multiple robots into a global pose graph, which it then feeds back to the robots to increase their mapping and localization effectiveness. The framework can potentially work with various SLAM algorithms, as long as they provide a pose graph with an image associated with each node, and absolute scaling. The merging of pose graphs is purely visual based and does not require well defined initial robot positions nor environment markers. To handle network delays, we propose a graph correction scheme that avoids using mutexes (and thus avoids modifying the existing SLAM system) by assuming local graph consistency. Furthermore, we propose a simple image feature filtering method that uses an associated depth image to filter image features unsuitable for scene recognition. We demonstrate the framework's functionality with several interior datasets that we have collected using three robots.
Articulated Robot Motion for Simultaneous Localization and Mapping (ARM SLAM)
Venue: IEEE Robotics and Automation Letters

A robot with a hand mounted depth sensor scans a scene. When the robot's joint angles are not known with certainty, how can it best reconstruct the scene? In this work, we simultaneously estimate the joint angles of the robot and reconstruct a dense volumetric model of the scene. In this way, we perform simultaneous localization and mapping in the configuration space of the robot, rather than in the pose space of the camera. We show using simulations and robot experiments that our approach greatly reduces both 3 D reconstruction error and joint angle error over simply using the forward kinematics. Unlike other approaches, ours directly reasons about robot joint angles, and can use these to constrain the pose of the sensor. Because of this, it is more robust to missing or ambiguous depth data than approaches that are unconstrained by the robot's kinematics.
Multi Robot Object Based SLAM
Venue: ISER

We propose a multi robot SLAM approach that uses 3D objects as landmarks for localization and mapping. The approach is fully distributed in that the robots only communicate during rendezvous and there is no centralized server gathering the data. Moreover, it leverages local computation at each robot (e.g. object detection and object pose estimation) to reduce the communication burden. We show that object based representations reduce the memory requirements and information exchange among robots, compared to point cloud based representations; this enables operation in severely bandwidth constrained scenarios. We test the approach in simulations and field tests, demonstrating its advantages over related techniques: our approach is as accurate as a centralized method, scales well to large teams, and is resistant to noise.
RGB D sensor based visual SLAM for localization and navigation of indoor mobile robot
Venue: 2016 International Conference on Advanced Robotics and Mechatronics (ICARM)

To increase the localization accuracy of the moving service robot in restaurant, A localization method and a landmark recognition method based on RGB and depth (RGB D) vision sensor is presented. Based on the landmarks, we utilized an Extend Kalman Filter(EKF) method to calculate robot position and pose. The path planning approach based on a differential flatness point to point trajectory planning is proposed for the robot. There are kinds of control manners which improved the enjoyment of human machine interface, such as mobile client and voice control. Finally, the proposed methods have been verified to be effective and feasible by experiment in indoor environments.

The adsorption of HCl on volcanic ash

Understanding the interaction between volcanic gases and ash is important to derive gas compositions from ash leachates and to constrain the environmental impact of eruptions. Volcanic HCl could potentially damage the ozone layer, but it is unclear what fraction of HCl actually reaches the stratosphere. The adsorption of HCl on volcanic ash was therefore studied from 76 to +150 degC to simulate the behavior of HCl in the dilute parts of a volcanic plume. Finely ground synthetic glasses of andesitic, dacitic, and rhyolitic composition as well as a natural obsidian from Vulcano (Italy) served as proxies for fresh natural ash. HCl adsorption is an irreversible process and appears to increase with the total alkali content of the glass. Adsorption kinetics follow a first order law with rate constants of 2.1310 6 s 1 to 1.8010 4 s 1 in the temperature range investigated. For dacitic composition, the temperature and pressure dependence of adsorption can be described by the equation lnc=1.26+0.27lnp 715.3/T, where c is the surface concentration of adsorbed HCl in mg/m2, T is temperature in Kelvin, and p is the partial pressure of HCl in mbar. A comparison of this model with a large data set for the composition of volcanic ash suggests that adsorption of HCl from the gas phase at relatively low temperatures can quantitatively account for the majority of the observed Cl concentrations. The model implies that adsorption of HCl on ash increases with temperature, probably because of the increasing number of accessible adsorption sites. This temperature dependence is opposite to that observed for SO2, so that HCl and SO2 are fractionated by the adsorption process and the fractionation factor changes by four orders of magnitude over a temperature range of 250 K. The assumption of equal adsorption of different species is therefore not appropriate for deriving volcanic gas compositions from analyses of adsorbates on ash. However, with the experimental data provided here, the gas compositions in equilibrium with the ash surfaces can be calculated. In particular, for dacitic composition, the molar ratio of S/Cl adsorbed to the ash surface is related to the molar S/Cl ratio in the gas phase according to the equation ln(S/Cl)adsorbed=2855T 1+0.28ln(S/Cl)gas 11.14. Our data also show that adsorption on ash will significantly reduce the fraction of HCl reaching the stratosphere, only if the initial HCl content in the volcanic gas is low <1 mol% For higher initial HCl concentrations, adsorption on ash has only a minor effect. While HCl scavenging by hydrometeors may remove a considerable fraction of HCl from the eruption column, recent models suggest that this process is much less efficient than previously thought. Our experimental data therefore support the idea that the HCl loading from major explosive eruptions may indeed cause severe depletions of stratospheric ozone.
Effect of disorders on topological phases in one dimensional optical superlattices

In a recent paper, Lang et al. proposed that edge states and topological phases can be observed in one dimensional optical superlattices. They showed that the topological phases can be revealed by observing the density profile of a trapped fermion system, which displays plateaus with their positions. However, disorders are not considered in their model. To study the effect of disorders on the topological phases, we introduce random potentials to the model for optical superlattcies. Our calculations show that edge states are robust against the disorders. We find the edge states are very sensitive to the number of the sites in the optical superlattice and we propose a simple rule to describe the relationship between the edge states and the number of sites. The density plateaus are also robust against weak disorders provided that the average density is calculated over a long interval. The widths of the plateaus are proportional to the widths of the bulk energy gaps when there are disorders. The disorders can diminish the bulk energy gaps. So the widths of the plateaus decrease with the increase of disorders and the density plateaus disappear when disorders are too strong. The results in our paper can be used to guide the experimental detection of topological phases in one dimensional systems.
Design of low phase noise substrate integrated waveguide oscillator based on complexquality factor (Qsc)
Venue: 2016 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)

A low phase noise substrate integrated waveguide (SIW) oscillator based on complex quality factor (Qsc) is presented. The oscillator employing a fourth degree cross coupled bandpass SIW filter is designed at the oscillation frequency for the feedback loop as a frequency stabilization element. In this paper, the peak frequency of the complex quality factor (Qsc) is adopted for oscillator design instead of designing the oscillator at groupdelay peak frequency conventionally. The measured phase noise performance of the developed oscillator is 141.4 dBc/Hz at 1MHz offset frequency with the figure of merit (FOM) of 198.3dBc/Hz.
Book Recommendation System through content based and collaborative filtering method
Venue: 2016 International Conference on Data Mining and Advanced Computing (SAPIENCE)

The online recommendation system has become a trend. Now a days rather than going out and buying items for themselves, reason being, online recommendation provides an easier and quicker way to buy items and transactions are also quick when it is done online. Recommended systems are powerful new technology and it helps users to find items which they want to buy. A recommendation system is broadly used to recommend products to the end users that are most appropriate. Online book selling Web sites now a days is competing with each other by considering many attributes. A recommendation system is one of the strongest tools to increase profits and retaining buyer. The existing systems lead to extraction of irrelevant information and lead to lack of user satisfaction. This paper presents Book Recommendation System (BRS) based on combined features of content based filtering (CBF) collaborative filtering (CF) and association rule mining to produce efficient and effective recommendation. For this we are proposing a hybrid algorithm in which we combine two or more algorithms, so it helps the recommendation system to recommend the book based on the buyer's interest.

Detecting Relic Gravitational Waves by Pulsar Timing Arrays: Effects of Cosmic Phase Transitions and Relativistic Free Streaming Gases

Relic gravitational waves (RGWs) generated in the early Universe form a stochastic GW background, which can be directly probed by measuring the timing residuals of millisecond pulsars. In this paper, we investigate the constraints on the RGWs and on the inflationary parameters by the observations of current and potential future pulsar timing arrays. In particular, we focus on effects of various cosmic phase transitions (e.g. e e annihilation, QCD transition and SUSY breaking) and relativistic free streaming gases (neutrinos and dark fluids) in the general scenario of the early Universe, which have been neglected in the previous works. We find that the phase transitions can significantly damp the RGWs in the sensitive frequency range of pulsar timing arrays, and the upper limits of tensor to scalar ratio r increase by a factor 2 for both current and future observations. However, the effects of free steaming neutrinos and dark fluids are all too small to be detected. Meanwhile, we find that, if the effective equation of state w in the early Universe is larger than 1/3, i.e. deviating from the standard hot big bang scenario, the detection of RGWs by pulsar timing arrays becomes much more promising.

Supply chain integration, landside operations and port accessibility in metropolitan Chicago

Seaports have traditionally been the focus of maritime logistics supply chains. Changing production patterns demanding greater end to end visibility by customers and accessibility to key inland population centers assume greater importance in the organization and design of transport resources and cargo flows. While synchronization of all aspects of the supply chain has become an operational necessity for firms, it is often held hostage to the efficiency of hinterland networks who must respond to a large group of stakeholders with sporadic coordination. This is particularly true when looking at the central US city and region of Chicago, a critical intermodal exchange point for truck, air and river barge traffic domestic and global, as well as a major central distribution location. This paper analyzes supply chain integration (SCI) efforts in the metropolitan Chicago region and considers efforts by public and private actors to collaborate for region wide SCI improvements. Pareto analysis suggests that concentrated freight corridors exist, influencing freight planning for regional transportation networks more directly than diffused regional freight movements. If the corridor service becomes less responsive or congested the corridor will move to different end nodes within the broad region. Regional planning must thus address national, regional, and local moves. Private/public sector infrastructure firms should address functional cooperation on SCI by focusing on corridors as well as local improvements.
Facilitating the Evolution of Esterase Activity from a Promiscuous Enzyme (Mhg) with Catalytic Functions of Amide Hydrolysis and Carboxylic Acid Perhydrolysis by Engineering the Substrate Entrance Tunnel
Venue: Applied and Environmental Microbiology

Promiscuous enzymes are generally considered to be starting points in the evolution of offspring enzymes with more specific or even novel catalytic activities, which is the molecular basis of producing new biological functions. Mhg, a typical a/b fold hydrolase, was previously reported to have both g lactamase and perhydrolase activities. However, despite having high structural similarity to and sharing an identical catalytic triad with an extensively studied esterase from Pseudomonas fluorescens, this enzyme did not show any esterase activity. Molecular docking and sequence analysis suggested a possible role for the entry of the binding pocket in blocking the entrance tunnel, preventing the ester compounds from entering into the pocket. By engineering the entrance tunnel with only one or two amino acid substitutions, we successfully obtained five esterase variants of Mhg. The variants exhibited a very broad substrate acceptance, hydrolyzing not only the classical p nitrophenol esters but also various types of chiral esters, which are widely used as drug intermediates. Site 233 at the entrance tunnel of Mhg was found to play a pivotal role in modulating the three catalytic activities by adjusting the size and shape of the tunnel, with different amino acid substitutions at this site facilitating different activities. Remarkably, the variant with the L233G mutation was a very specific esterase without any g lactamase and perhydrolase activities. Considering the amino acid conservation and differentiation, this site could be a key target for future protein engineering. In addition, we demonstrate that engineering the entrance tunnel is an efficient strategy to regulate enzyme catalytic capabilities.  Promiscuous enzymes can act as starting points in the evolution of novel catalytic activities, thus providing a molecular basis for the production of new biological functions. In this study, we identified a critical amino acid residue (Leu233) at the entry of the substrate tunnel of a promiscuous enzyme, Mhg. We found that substitution of this residue with smaller amino acids such as Gly, Ala, Ser, or Pro endowed the enzyme with novel esterase activity. Different amino acids at this site can facilitate different catalytic activities. These findings exhibited universal significance in this subset of a/b fold hydrolases, including Mhg. Furthermore, we demonstrate that engineering the entrance tunnel is an efficient strategy to evolve new enzyme catalytic capabilities. Our study has important implications for the regulation of enzyme catalytic promiscuity and development of protein engineering methodologies.
Flexible operation of CSIRO's post combustion CO2 capture pilot plant at the AGL Loy Yang power station

Flexible operation has the potential to significantly improve the economic viability of post combustion CO 2 capture (PCC) However, the impact of disturbances from flexible operation of the PCC process is unclear. The purpose of this study was to investigate the effects of flexible operation in a PCC pilot plant by implementing step changes for improved dynamic data reliability. The flexible operation campaign was conducted at the CSIRO PCC pilot plant at AGL Loy Yang using monoethanolamine (MEA) absorbent. The pilot plant was operated under a broad range of transient conditions (changing flue gas flow, liquid absorbent flow and steam pressure) to capture the dynamics of a PCC process during flexible operation. The study demonstrated that the dynamics of flue gas flow rate was faster than absorbent flow rate. The greatest CO 2 removal% was achieved at the lowest flue gas flow rate or at the highest absorbent flow rate; however, the latter provided improved energy efficiency. The steam pressure parameter could adjust the temperature of all columns simultaneously which can be used to compensate for effects from ambient conditions or heat losses. These results verify the technical feasibility of flexible PCC operation and provide a suitable dataset for dynamic model validation.
The gamma ray source AGL J2241+4454 as the possible counterpart of MWC 656

The AGILE satellite discovered the transient source AGL J2241+4454 in 2010 which triggered the study of the associated field allowing for the discovery of the first Be/black hole binary system: MWC 656. This binary was suggested to be the counterpart of AGL J2241+4454, but this is still not a firm association. In this work we explore the archival AGILE and Fermi/LAT data in order to find more transient events originating in the field of AGL J2241+4454 and address the possibility to link them to the accretion/ejection processes of MWC 656. We found a total of 9 other transient events with AGILE compatible with the position of AGL J2241+4454, besides the one from 2010. We folded this events with the period of the binary system and we did not find significant results that allow us to associate the gamma ray activity to any particular orbital phase. By stacking the 10 transient events we obtained a spectrum that extends between 100 MeV and 1 GeV, and we fitted it with a power law with photon index \Gamma} 2.3 0.2. We searched into the Fermi /LAT data in order to complement the gamma ray information provided by AGILE but no significant results arose. In order to investigate this apparent contradiction between the two gamma ray telescopes, we studied the exposure of the field of AGL J2241+4454 in both instruments finding significant differences. In particular, AGILE exposed for longer time and at lower off axis angle distance the field of AGL J2241+4454. This fact, together with the energy dependent sensitivity of both instruments, and the soft spectrum found in the stacking analysis, might explain why AGILE observed the transient events not seen by Fermi/LAT.
Spectrum of AGL mutations in Chinese patients with glycogen storage disease type III: identification of 31 novel mutations
Venue: Journal of Human Genetics

Glycogen storage disease type III (GSD III) a rare autosomal recessive disease characterized by hepatomegaly, fasting hypoglycemia, growth retardation, progressive myopathy and cardiomyopathy, is caused by deficiency of the glycogen debranching enzyme (AGL) Direct sequencing of human AGL cDNA and genomic DNA has enabled analysis of the underlying genetic defects responsible for GSD III. To date, the frequent mutations in different areas and populations have been described in Italy, Japan, Faroe Islands and Mediterranean area, whereas little has been performed in Chinese population. Here we report a sequencing based mutation analysis in 43 Chinese patients with GSD III from 41 families. We identified 51 different mutations, including 15 splice site (29.4% 11 small deletions (21.6% 12 nonsense (23.5% 7 missense (13.7% 5 duplication (9.8% and 1 complex deletion/insertion (2.0% 31 of which are novel mutations. The most common mutation is c.1735+1G>T (11.5% The association of AGL missense and small in frame deletion mutations with normal creatine kinase level was observed. Our study extends the spectrum of AGL mutations and suggests a genotype phenotype correlation in GSD III.
