Low-Noise Repetition-Rate Multiplication by Injection Locking and Gain- Saturated Amplification

Low-noise repetition-rate multiplication of optical pulses is demonstrated through harmonic injection locking of a mode-locked laser and gain-saturated amplification by a semiconductor optical amplifier (SOA). The approach employs strong optical injection for lowering the repetition-rate phase noise, followed by gain-saturated SOA for suppression of pulse intensity irregularities. In this way, we can achieve low phase noise level and high side-mode suppression ratio (SMSR) at the same time. Experimentally, we show repetition-rate multiplication of a 250-MHz commercial mode-locked laser to 1-GHz repetition-rate, with 3% modulation depth, 33-dB SMSR, and 14-fs absolute rms timing jitter (when integrated from 10 kHz to 10 MHz offset frequency).
Experience Upgrading Control Systems at the Gemini Telescopes

The real-time control systems for the Gemini Telescopes were designed and built in the 1990s using stateof-the-art software tools and operating systems of that time. These systems are in use every night, but they have not been kept up-to-date and are now obsolete and also very labor intensive to support. This led Gemini to engage in a major effort to upgrade the software on its telescope control systems. We are in the process of deploying these systems to operations, and in this paper we review the experience and lessons learned through this process and provide an update on future work on other obsolescence management issues.
Structural alterations in grey matter volume related to autobiographical memory retrieval

Autobiographische Erinnerungen werden haufig als grundlegende Voraussetzung fur die intrinsisch generierten Gedankengange des neuronalen Default Mode Netzwerkes (DMN) angesehen. Der emotionale Gehalt einer personlichen Erinnerung unterscheidet sich traditionell auf zwei Ebenen, der Valenz und der Intensitat eines Ereignisses. Bisher wurde struktureller Variabilitat auf neuronaler Ebene innerhalb des DMN in Bezug auf das Abrufen emotionaler personlicher Erinnerungen wenig Aufmerksamkeit geschenkt. Das Ziel dieser Studie war es, die strukturelle Variabilitat zwischen gesunden Probanden in Abhangigkeit der Variablen Valenz und Intensitat zu untersuchen. Regionale Unterschiede im Volumen der grauen Hirnsubstanz wurden mittels voxel-basierter Morphometrie (VBM) und DARTEL untersucht. Positive Valenz korrelierte signifikant mit hoherem Volumen grauer Hirnsubstanz im inferioren frontalen Gyrus und im Hippocampus sowie parahippocampalem Gyrus. Diese Regionen werden mit der Ruckerinnerung als auch mnestischen Zugangs- und Konstruktionsprozessen assoziiert. Negative Valenz korrelierte mit groserem Volumen der grauen Hirnsubstanz im linken medialen frontalen Gyrus. Des weiterem konnte gezeigt werden, dass geringere Intensitat mit signifikant hoherem Volumen der grauen Hirnsubstanz in den Kernbereichen des DMN, dem posterioren cingularen Cortex, dem inferioren temporalen Gyrus und dem medialen frontalen Gyrus korrelierte. Insgesamt zeigen die Ergebnisse dieser Studie strukturelle Variabilitat innerhalb vieler Regionen des DMN und seiner Subsysteme, die mit mnestischen Mechanismen des autobiographischen Erinnerns in Verbindung stehen.
Long term outcomes of on-pump CABG versus off-pump CABG

Objective: Assess the long-term outcomes including mortality, revascularization and myocardial infarction events to determine whether off-pump CABG is more effective for patients compared to onpump CABG procedures. Methods: Studies were found using PubMed with the search term, “on and off pump CABG” which yielded 1736 studies. After assessing for records within 5 years the search was narrowed to 370 articles and then down to 353 because some articles were not available in full-text. Our search was then divided into first looking at randomized control trials and meta-analysis availability from the 353 articles meeting our criteria. After narrowing our search for only randomized control trials, we were left with 47 articles. We lastly went back to the 353 articles and narrowed that search to only available metaanalysis which gave us 27 options. The final studies were chosen based on their relation to our clinical question. Results: Studies show that there are no significant differences in the number of events sustained (or occurring) after both the off-pump CABG and on-pump CABG procedures. This was evident by results that varied between the three studies in which all percentages were close in number of events per population. Conclusion: In regard to deciding whether to perform on-pump CABG or off-pump CABG, the physician and patient need to make a joint decision based on the patient’s comorbidities and the physician’s experience as a surgeon. There is not conclusive evidence that one approach is more effective than the other.
A 3D Virtual Sketching System Using NURBS Surfaces and Leap Motion Controller

A 3D sketching system is presented for transforming an ideation to an actual CAD model using Human Computer Interaction (HCI). The system uses a Leap motion controller to capture human gestures, and translated them by a recognition model. The pinch and pull gestures are used to represent actions for flexible manipulations on control points coordinates of NURBS surfaces. The continuous motion of the designers hands is converted to morphological/geometrical and mathematical values. Both cases of single and dual hands are developed, offering the designer a variety of resolution tools to convey their ideas and creativity.
Existing and Emerging Approaches to Treating Chronic Inflammatory Demyelinating Polyneuropathy

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare disabling disease with an incompletely understood autoimmune etiology. Differentiating the condition from other neurological diseases can be challenging and appropriate treatment is often delayed. Intravenous immunoglobulin (IVIg), plasmapheresis, corticosteroids and subcutaneous immunoglobulin (SCIg) have all been demonstrated to be beneficial in placebo-controlled, randomized clinical trials. Corticosteroids, including methylprednisolone and dexamethasone are effective and frequently used in CIDP but their long-term use is limited by side effects. One of the most commonly prescribed treatments for CIDP is IVIg which diminishes inflammatory processes and prevents disease progression. Treatment with IVIg has proven effective in randomized, double blind, placebo controlled, clinical trials and the results support its use in CIDP. For some patients, the benefit of IVIg, is limited by the frequency of infusions and systemic side effects such as flu-like symptoms, headache, and nausea. Other effective treatments for CIDP include corticosteroids that are associated with serious side effects in long-term use and plasmapheresis which requires specialized facilities. More recently, SCIg has been demonstrated in double blind, placebo-controlled studies to be effective for maintenance use in CIDP in patients whose disease has been controlled by IVIg. In a large clinical trial, 0.2 g/kg and 0.4 g/kg body weight doses of 20% SCIg equivalent to 1 mL/kg or 2 mL/kg, respectively, administered weekly, demonstrated efficacy in CIDP and were well tolerated. Immunomodulating treatments such as cyclophosphamide, mycophenolate mofetil and rituximab have also shown efficacy in select populations with CIDP.
A New Ratio Statistic to Test Mean Change Point in Long Memory Time Series

In this paper, we propose a new ratio statistic to test mean change point in long memory time series. We derive the test statistic converges to a non-degenerate distribution under the null hypothesis and that it diverges to infinity under the alternative of a change-point with constant height. Furthermore, we estimate the long memory parameters and approximate the critical values of the statistic by the Sieve Bootstrap method. We show the size and power properties of our test through numerical simulations and the performance is inspiring. Finally, we illustrate the effectiveness of this method through a set of actual data.
Soil resilience under different scenarios of fire recurrence and severity in Pinus forest ecosystems affected by large wildfires

Fire is as a global phenomenon that represents one of the main disturbances in the Mediterranean Pinus forest ecosystem. It is also considered to be a soil forming factor and temporary modifier of soil properties. The degree of this impact depends on different factors such as pre-fire conditions, the type of soils affected, topographic and metereological characteristics and fire-regime attributes (e.g. fire size, recurrence, burn severity). In the last few decades, the fire regime is changing in some regions of the world including the Iberian Peninsula. This is the result of land abandonment, fire suppression policies and climate change. These factors generate a more favourable environment for the occurrence of large forest fires that may play a key role in affecting the natural rates and patterns of soils structure and functioning. As a consequence, both resiliency and sustainability of Mediterranean Pinus forest could be engaged. This survey is aimed at getting to know the effects of combined fire-regime attributes (recurrence and severity) on soil biochemical properties from a medium-term perspective (four years). The study was conducted in the Sierra del Teleno mountain range (León province; NW Iberian Peninsula). The climate is Mediterranean with 2-3 months’ dryness in summer. Soils are acidic (pH around 4.8) and mainly classified as Cambisol and Leptosol. A large wildfire occurred on August 19 th 2012 affected an area of 119 km 2 (103 km 2 being occupied by Pinus pinaster Ait. forests). In this wildfire, a fire recurrence-severity map was elaborated by remote sensing methods, and validated using ground truth and with the information provided by the Regional Administration. We characterized fire recurrence throughout a 16-year period (1998-2014). Fire severity was measured by the dNBR (difference of the Normalized Burn Ratio) spectral index, and classified according to the ground reference values of the CBI (Composite Burn Index). We differentiated four scenarios of recurrence (low and high) and severity (low and high), and established a minimum of five 30m*30m field plots in each of the four recurrence-severity scenarios. In each field plot, we collected soil samples from a depth of 0-3 cm four years after the fire, and analysed the enzymatic activities β-glucosidase, urease, and acid-phosphatase and microbial biomass carbon. Four years after the fire, it can be observed that fire-regime attributes have a great influence on the resilience of soil properties. In the scenario of low recurrence-high severity, which means the highest intensity fire, decreased phosphatase and urease activities and soil microbial biomass carbon. This scenario showed a slight resilience to β-glucosidase activity but marked depletion in the other soil properties. High recurrence scenarios favour the recovery of soil biochemical and microbial properties. Soil enzymatic activities and microbial biomass could be a proxy to identify the general state of soil health after large fires.
Applying backfilling over a non-dedicated cluster

The resource utilization level in open laboratories of several universities has been shown to be very low. Our aim is to take advantage of those idle resources for parallel computation without disturbing the local load. In order to provide a system that lets us execute parallel applications in such a non-dedicated cluster, we use an integral scheduling system that considers both Space and Time sharing concerns. For dealing with the Time Sharing (TS) aspect, we use a technique based on the communication-driven coscheduling principle. This kind of TS system has some implications on the Space Sharing (SS) system, that force us to modify the way job scheduling is traditionally done. In this paper, we analyze the relation between the TS and the SS systems in a non-dedicated cluster. As a consequence of this analysis, we propose a new technique, termed 3DBackfilling. This proposal implements the well known SS technique of backfilling, but applied to an environment with a MultiProgramming Level (MPL) of the parallel applications that is greater than one. Besides, 3DBackfilling considers the requirements of the local workload running on each node. Our proposal was evaluated in a PVM/MPI Linux cluster, and it was compared with several more traditional SS policies applied to non-dedicated environments.
Pinpointing Mechanisms of a Mechanistic Treatment: Dissociable Roles for Overt and Covert Attentional Processes in Acute and Long-Term Outcomes Following Attention-Bias Modification

Biased patterns of attention toward threat are implicated as key mechanisms in anxiety that can be modified through automated intervention (attention-bias modification; ABM). Intervention refinement and personalized dissemination efforts are substantially hindered by gaps in understanding the precise attentional components that underlie ABM’s effects on symptoms—particularly with respect to longer-term outcomes. Seventy adults with transdiagnostic anxiety were randomized to receive eight sessions of active ABM (n = 49) or sham training (n = 21). Reaction time and eye-tracking data, collected at baseline, posttraining, and 1-month follow-up, dissociated multiple core attentional processes spanning overt and covert processes of engagement and disengagement. Self-reported symptoms were collected out to 1-year follow-up. Covert disengagement bias was specifically reduced by ABM, unlike all other indices. Overt disengagement bias at baseline predicted acute post-ABM outcomes, whereas covert engagement bias was nonspecifically predictive of symptom trajectories out to 1-year follow-up. Results suggest unique and dissociable roles for each discrete mechanism.
Robust Space–Frequency Joint Representation for Remote Sensing Image Scene Classification

Remote sensing image scene classification is a fundamental problem, which aims to label an image with a specific semantic category automatically. Recent progress on remote sensing image scene classification is substantial, benefitting mostly from the powerful feature extraction capability of convolutional neural networks (CNNs). Even though these CNN-based methods have achieved competitive performances, they only construct the representation of the image in location-sensitive space-domain. As a result, their representations are not robust to rotation-variant remote sensing images, which influence the classification accuracy. In this paper, we propose a novel feature representation method by introducing a frequency-domain branch to the traditional only-space-domain architecture. Our framework takes full advantages of discriminative features from space domain and location-robust features from the frequency domain, providing more advanced representations through an additional joint learning module, a property that is critically needed to perform remote sensing image scene classification. Additionally, our method produces satisfactory performances on four public and challenging remote sensing image scene data sets, Sydney, UC-Merced, WHU-RS19, and AID.
Enhanced Buck-Boost dc-dc Converter with Positive Output Voltage

In this paper, a new transformerless buck-boost converter is presented. The voltage gain of the converter is higher than the classic boost converter, classic buck-boost converter, CUK and SEPIC converters. The proposed converter advantage is buck-boost capability. The proposed converter topology is simple; therefore, the converter control is simple. The converter has one main switch. Hence, the switch with low switching and conduction losses can be used. The stress of the main switch is low; therefore, switch with low on-state resistance can be selected. The principles of the converter and mathematic analyses are presented. The validity of the accuracy of calculations is verified by the experimental results.
p-Channel GaN Transistor Based on p-GaN/AlGaN/GaN on Si

In this letter, we demonstrate a recessed-gate p-channel MISFET using a p-GaN (70 nm)/Al <sub>0.2</sub>Ga<sub>0.8</sub>N (15 nm)/GaN heterostructure grown by metalorganic chemical vapor deposition (MOCVD) on a Si substrate. A major benefit of such epi-structure is that it contains both a 2-dimensional electron gas (2-DEG) and a 2-dimensional hole gas (2-DHG), hence making it suitable for the GaN-based complementary circuit implementation. In addition, the 2-DEG at the interface of the AlGaN/GaN heterostructure is depleted due to the p-GaN layer on top giving rise to normally- OFF operation for the n-channel transistors.

Topology Control in an Indoor Wireless Sensor Network using Realistic Propagation Models

Topology Control in an Indoor Wireless Sensor Network using Realistic Propagation Models Gagan Goel Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2014 This thesis considers the problem of designing an energy-efficient communication backbone for a wireless sensor network deployed in an indoor environment. We propose and implement a Topology Control scheme to determine optimal sensor node transmission power levels that maintain a desired level of network connectivity. Power optimized singly connected network is constructed using a Minimum Spanning Tree based formulation. To achieve fault-tolerance, we employ a Matroid Intersection based approach to construct a Minimum Cost Rooted k-Outconnected Spanning Subgraph, basis for the computation of a Minimum Power k-Connected Spanning Subgraph, k > 1. Realistic wireless channel assumptions are made to construct the optimized network topologies. Field measurements are performed in an indoor office setup to characterize the channel parameters and hence evaluate the accuracy of various path loss models suitable for such propagation environments. Network simulations validate the necessity of exercising Topology Control to achieve network longevity.

The overall base composition of the whole mitochondrial genome was A (27.86%), T (24.88%), G (17.16%), and C (30.10%) with an AT bias of 52.94%. The longest protein-coding genes of these species was ND5, whereas the shortest ATP8.
Determination of Barreling of Aluminum Solid Cylinders During Cold Upsetting Using Genetic Algorithm

This study presents Genetic Programming models for the formulation of barreling of aluminum solid cylinders during cold upsetting based on experimental results. The maximum and minimum radii of the barreled cylinders having different aspect ratio (d/h= 0.5, 1.0 and 2.0) were measured for various frictional conditions (m=0.1-0.4). The change in radii with respect to height reduction showed different trends before and after folding, therefore, the corresponding reduction ratios of folding were also determined by using incremental upsetting. Genetic programming models were prepared using the experimental results with the input variables of the aspect ratio, the friction coefficient, and the reduction in height. The minimum and maximum barreling radii were formulated as output taking the folding into consideration. The performance of proposed GP models are quite satisfactory (R2 = 0.908-0.998). Keywords: Upset, forging, barreling, bulging, axisymmetric compression.
Evaluation of the Mobility Station in Domagkpark, Munich

The Mobility Station of Domagkpark opened on May 31, 2016 with many members already registered at its main provider, STATTAUTO Munchen. One year later, the number of registered members has doubled and the effects of the measure are visible in the district. It is a small private mobility station that provides the inhabitants of the district of Domagkpark with car-sharing and bike-sharing services, promoting electro mobility through the use of electric vehicles. The present thesis has evaluated the Mobility Station of Domagkpark, considering its impact on selected key performance indicators. The findings show that a private mobility station can have a significant impact on car ownership reduction and vehicle kilometres travelled. Also, it can influence positively the travel behaviour of the inhabitants of a district. Through an impact and process evaluation regarding the framework of the CIVITAS initiative co-financed by the European Commission, positive findings have been made that support further similar sustainable mobility measures. The impact evaluation consisted on a survey conducted among the inhabitants of the district between the months of April and May, 2017. For the process evaluation, different interviews with stakeholders of the project were done as well as a learning history workshop.
