Conventional repair of total anomalous venous drainage without primary sutureless technique: surgical tips to prevent pulmonary vein obstruction
Venue: General Thoracic and Cardiovascular Surgery
Year: 2018

ObjectivesAlthough primary sutureless technique for total anomalous pulmonary venous drainage has been introduced to reduce postoperative pulmonary vein obstruction (PVO) controversy still exists about superiority of the procedure between the conventional repair and primary sutureless technique at the initial repair. In our unit, the conventional repair has been consistently used based on four important surgical policies: (1) mark incision lines between 2 chambers to gain anatomically natural alignment, (2) place precise stitches by "intima to intima" using monofilament suture, (3) adequate orifice size should be guaranteed in greater than expected mitral valve size, (4) do not hesitate to undertake a redo additional anastomosis by a different approach when an echocardiography shows the velocity more than 1.5 m/s. This study aims to evaluate mid term outcome of the conventional repair for total anomalous pulmonary venous drainage.MethodsBetween 2004 and 2016, consecutive 15 patients who underwent the conventional repair without the primary sutureless technique were included in this study. Survival, Freedom from reoperation, and PVO were retrospectively reviewed.ResultsMean follow up period was 4.6 3.7 years. Except for one patient who died of uncontrollable pleural effusion, all other patients survived with 5 year survival rate of 93.3% For the 14 survivors, there was no PVO, nor reoperation.ConclusionsFollowing these policies, the mid term outcome of the conventional total anomalous pulmonary venous drainage repair was excellent without the primary sutureless technique showing no obstruction. The conventional repair can be safely applied at the initial operation when the morphological condition allows for it.
Intelligent path planning for automated guided vehicles system based on topological map
Venue: 2012 IEEE Conference on Control, Systems Industrial Informatics
Year: 2012

Path planning is one of the key aspects of designing and implementing intelligent robots. This paper presents a novel path planning approach for automated guided vehicles (AGVs) In the proposed approach, the overall AGV control system is introduced and the environment is modeled as topological map. An improved version of classical Dijkstra's algorithm is developed aiming to find the globally optimal path which is a set of nodes of the warehouse topological map. Also, the local path planning is addressed by using a heuristics based algorithm A* algorithm which searches for the local minimum path between every two neighbor nodes of the global path. To assess the performance of the suggested algorithms, a number of simulation experiments are carried out for a range of scenarios. The result demonstrates the effectiveness of the algorithmic design and the AGV path planning solution.
Approaches and applications of semi blind signal extraction for communication signals based on constrained independent component analysis: The complex case
Venue: Neurocomputing
Year: 2013

Signals of interest (SOIs) extraction are a vital issue in the field of communication signal processing. A promising approach is constrained independent component analysis (cICA) This paper extends the conventional constrained independent component analysis framework to the case of complex valued mixing model and presents different prior information and different ways to be incorporated into the cICA framework. Two examples are demonstrated, ICA with cyclostationary constraint (ICA CC) and ICA with spatial constraint (ICA SC) The adaptive solution using the gradient ascent learning process is derived to solve the new constrained optimization problem in the ICA CC example, while the rough spatial information corresponding to the direction of arrival (DOA) of the SOI can be utilized to select the specific initial vector for the desired solution before the learning process in the ICA SC example. The corresponding experiment results show the efficacy and accuracy of the proposed algorithms.
Southern Ocean deep convection as a driver of Antarctic warming events
Year: 2016

Simulations with a free running coupled climate model show that heat release associated with Southern Ocean deep convection variability can drive centennial scale Antarctic temperature variations of up to 2.0 degC. The mechanism involves three steps: Preconditioning: heat accumulates at depth in the Southern Ocean; Convection onset: wind and/or sea ice changes tip the buoyantly unstable system into the convective state; Antarctic warming: fast sea ice albedo feedbacks (on annual decadal timescales) and slow Southern Ocean frontal and sea surface temperature adjustments to convective heat release (on multidecadal century timescales) drive an increase in atmospheric heat and moisture transport toward Antarctica. We discuss the potential of this mechanism to help drive and amplify climate variability as observed in Antarctic ice core records.

Parliamentary questions and oversight in the European Union
Year: 2011

Delegation in the European Union (EU) involves a series of principal agent problems, and the various chains of delegation involve voters, parties, parliaments, govern ments, the European Commission and the European Parliament. While the literature has focused on how government parties attempt to monitor EU affairs through committees in national parliaments and through Council committees at the EU level, much less is known about the strategies opposition parties use to reduce informational deficits regarding Euro pean issues.This article argues that the European Parliament (EP) offers opposition parties an arena to pursue executive oversight through the use of written parliamentary questions. Using a novel dataset on parliamentary questions in the EP, this article examines why Members of the European Parliament (MEPs) ask questions of specific Commissioners. It transpires that MEPs from national opposition parties are more likely to ask questions of Commissioners. Questions provide these parties with inexpensive access to executive scru tiny.This finding has implications for the study of parliamentary delegation and party politics inside federal legislatures such as the EP.

Synthesis of Bi2MoO6 Nanosheets with Rich Oxygen Vacancies by Postsynthesis Etching Treatment for Enhanced Photocatalytic Performance
Year: 2018

Controlled introduction of oxygen vacancies in metal oxide based photocatalysts could improve their charge carrier separation efficiencies to enhance their photocatalytic performances. In this work, oxygen vacancies were introduced in Bi2MoO6 nanosheets through a postsynthesis etching treatment by NaOH aqueous solution at room temperature for the first time, which removed the requirement of high temperature treatment, chemicals of high cost and environmental hazardness, or specific apparatus for the introduction of oxygen vacancies in previous studies. Furthermore, the crystal structure, morphology, optical properties, and energy band structures of these Bi2MoO6 nanosheets were not changed by this approach, which allowed the separation and illustration of the charge carrier separation role of oxygen vacancies for the photocatalytic performance enhancement. With the increase of oxygen vacancies, Bi2MoO6 nanosheets demonstrated improved electron hole separation efficiency and largely enhanced photocatalytic.
Adaptive Asynchronous Parallelization of Graph Algorithms
Venue: ACM Trans. Database Syst.
Year: 2020

This article proposes an Adaptive Asynchronous Parallel (AAP) model for graph computations. As opposed to Bulk Synchronous Parallel (BSP) and Asynchronous Parallel (AP) models, AAP reduces both stragglers and stale computations by dynamically adjusting relative progress of workers. We show that BSP, AP, and Stale Synchronous Parallel model (SSP) are special cases of AAP. Better yet, AAP optimizes parallel processing by adaptively switching among these models at different stages of a single execution. Moreover, employing the programming model of GRAPE, AAP aims to parallelize existing sequential algorithms based on simultaneous fixpoint computation with partial and incremental evaluation. Under a monotone condition, AAP guarantees to converge at correct answers if the sequential algorithms are correct. Furthermore, we show that AAP can optimally simulate MapReduce, PRAM, BSP, AP, and SSP. Using real life and synthetic graphs, we experimentally verify that AAP outperforms BSP, AP, and SSP for a variety of graph computations.
The Dual Role of Surfactant Protein D in Vascular Inflammation and Development of Cardiovascular Disease
Venue: Front. Immunol.
Year: 2019

Cardiovascular disease (CVD) is responsible for 31% of all global deaths. Atherosclerosis is the major cause of cardiovascular disease and is a chronic inflammatory disorder in the arteries. Atherosclerosis is characterized by the accumulation of cholesterol, extracellular matrix, and immune cells in the vascular wall. Recently, the collectin surfactant protein D (SP D) an important regulator of the pulmonary immune response, was found to be expressed in the vasculature. Several in vitro studies have examined the role of SP D in the vascular inflammation leading to atherosclerosis. These studies show that SP D plays a dual role in the development of atherosclerosis. In general, SP D shows anti inflammatory properties, and dampens local inflammation in the vessel, as well as systemic inflammation. However, SP D can also exert a pro inflammatory role, as it stimulates C C chemokine receptor 2 inflammatory blood monocytes to secrete tumor necrosis factor a and increases secretion of interferon g from natural killer cells. In vivo studies examining the role of SP D in the development of atherosclerosis agree that SP D plays a proatherogenic role, with SP D knockout mice having smaller atherosclerotic plaque areas, which might be caused by a decreased systemic inflammation. Clinical studies examining the association between SP D and cardiovascular disease have reported a positive association between circulatory SP D level, carotid intima media thickness, and coronary artery calcification. Other studies have found that circulatory SP D is correlated with increased risk of both total and cardiovascular disease mortality. Both in vitro, in vivo, and clinical studies examining the relationship between SP D and CVDs will be discussed in this review.
Buckling and post buckling of a stiff film resting on an elastic graded substrate
Year: 2012

Systems consisting of a hard layer resting on an elastic graded soft substrate are frequently encountered both in nature and industry. In this paper, we study the surface wrinkling problem of such a composite system subjected to in plane compression. The Young's modulus of the elastic substrate is assumed to vary along its depth direction. In particular, we investigate two typical variations in the modulus, described by a power function and an exponential function, respectively. Analytical solutions which permit to determine the critical compressive strain for the onset of wrinkling and the wrinkling wavelength are derived. A series of finite element simulations are performed to validate the theoretical solutions and demonstrate the prominent features of the postbuckling evolution of the system. The results may not only find applications in thin film metrology and surface patterning but also provide insight into the wrinkling phenomena of various living tissues.
The Potential Impact of COVID 19 on Student Learning and How Schools Can Respond
Venue: Educational Measurement, Issues and Practice
Year: 2020

There is no denying the impact that the coronravirus disease (COVID 19) outbreak has had on many aspects of our lives. This article looks at the potential impact of COVID 19 on student learning as schools abruptly morphed into virtual learning environments using data from several instructional, practice, and assessment solutions offered by Renaissance. First, three hypothetical learning scenarios are considered using normative data from Star assessments to explore the potential impact on reading and math test performace. Next, data on Focus Skills are used to highlight which grades may have missed the most foundational math and reading content if instruction was stopped or reduced. Last, data from two of Renaissance's practice tools are used to evaluate whether students were practicing key skills following school closures. The article concludes that academic decline will likely occur but may be tempered by the increased use of practice tools; effects may look different for math and reading; and may impact grades and schools differently. As such, schools may need to leverage decision making frameworks, such as the Multi tiered Systems of Support/Response to Intervention (MTSS/RTI) framework, more than ever to identify needs and target instruction where it matters most when school begins in fall 2020.
Further Evaluation of Teaching Behavior Technicians to Input Data and Graph Using GraphPad Prism.
Venue: Behavior analysis
Year: 2020

We replicated and extended Mitteer, Greer, Fisher, and Cohrs (2018) by examining the effects of a video model on inputting data into GraphPad Prism, which is a necessary skill for graph construction. We used a concurrent multiple probe across behavior design with two behavior technicians to assess data input and graphing skills separately prior to and during access to relevant video models. We evaluated the generality of the training procedures by assessing both skills during data input plus graphing sessions without access to the video models. The video models resulted in mastery of data input and graphing skills when assessed individually. We observed training effects generalize to data input plus graphing sessions once behavior technicians experienced all relevant video models. These results suggest that individuals should view both data input and graphing video models prior to depicting single case design data in Prism but that these skills can maintain at high levels of accuracy without continued access to the training materials.
Design optimization of electrostatic sensor electrodes via MOPSO
Year: 2020

An ideal electrostatic sensor with optimized electrodes is required for solid particles (SPs) velocity determination. The simplicity and reliability of the multi objective particle swarm optimization (MOPSO) imparted further impetus to the accurate determination of SPs velocity using electrostatic sensors. This paper reports a new design of electrostatic sensors via MOPSO, where the sensors geometry is determined using response surface methodology (RSM) Besides, electrode sensing factors including spatial sensitivity and statistical error of electrostatic sensors are considered for the optimization. Parameters such as electrode dimensions, velocity, and distribution of particles in the pipeline are found to greatly influence the electrodes sensing performance. Electrodes with different physical sizes were applied to find their optimal value to attain minimum statistical error and maximum spatial sensitivity, which were optimization targets. Following RSM and MOPSO methods, an electrode's optimum length of 0.6 cm and thickness of 0.5 cm has been achieved. It is established that the electrodes spatial sensitivity distribution appears uniform due to their size optimization. Furthermore, very thin electrodes with short length are determined to be prerequisite for sensitivity enhancement. Present study finds a theoretical basis for the electrostatic electrodes optimal design.
Metacognitive approach to narrative persuasion: the desirable and undesirable consequences of narrative disfluency
Venue: Media Psychology
Year: 2020

The current article tests the metacognitive proposition that the relative ease or difficulty with which narrative messages are processed can affect subsequent judgment. Challenging the assertion that experienced disfluency is mostly negative and undesirable, it is argued that disfluent (difficult to process) narratives are well positioned to facilitate narrative persuasion when people hold value laden beliefs. Using the controversial context of physician assisted suicide, two experiments (N1 204, N2 558) demonstrate that a metacognitive experience of difficulty is used to infer positions regarding the narrative message. The article then proceeds to test a theoretical model, showing that fluent narratives gain their strength by facilitating the experience of flow among ambivalent individuals, whereas disfluent narratives can challenge value laden beliefs by attenuating attitude certainty. Implications are discussed and future directions for a metacognitive approach to narrative persuasion are offered.
