Ch Ch Ch changes: How Action Phase Functional Leadership, Team Human Capital, and Interim vs. Permanent Leader Status Impact Post transition Team Performance
Year: 2017

This study addresses the following: (1) does a team leader change along with the quality of the team's human capital affect post change team performance? (2) is functional leadership of the team's human capital a driver of post change team performance? and (3) should interim vs. permanent leaders manage the team's human capital differently? We analyzed archival data from Major League Baseball teams who had undergone an in season manager change (N 129) Team performance improved after a leader change, and the quality of the team's strategic and non strategic core human capital were positively related to post change performance. New leaders who engaged in more active functional leadership of the strategic core human capital enhanced the positive effects of human capital quality. Additionally, active functional leadership enhanced the positive effects of strategic core human capital for interim replacement leaders, but not for permanent replacement leaders. This study extends theory and practice on the importance of functional team leadership and human capital following a leader transition. As such, our results provide actionable knowledge for organizations and managers who are part of leadership transitions. This empirical study leverages a unique sample to provide insights into the implications of team leader transitions. The results of this study shed light on the impact that leader transitions which involve "interim" and "permanent" replacements may have on post transition team performance and how these different types of leaders should leverage the inherent human capital that exists within the team.
A Novel Image Quality Assessment Index for EdgeAware Noise Reduction in Low Dose Fluoroscopy:Preliminary Results
Venue: 2020 International Conference on e Health and Bioengineering (EHB)
Year: 2020

X ray fluoroscopy is a medical imaging modality that provides continuous real time screening of patient's organs and various radiopaque surgical objects. Fluoroscopy usually requires long and unpredictable exposure times, thus radiation intensity must be heavily reduced to limit patient's dose. This gives rise to the well known Poisson noise, which results in very poor image quality. Commercial fluoroscopes usually improve image quality via real time temporal averaging, which produces motion blur in moving scenes. The Noise Variance Conditioned Average (NVCA) algorithm exploits the a priori knowledge of Poisson noise statistics to provide efficient noise reduction, while preserving the edges of moving objects. However, accurate setting of NVCA parameters is required to achieve the best results, and this could be supported by image quality assessment (IQA) indices. This study presents a novel, edge aware IQA index, named Sensitivity of Edge Detection (SED) and compares it against the well established Feature Similarity (FSIM) index, to assess their efficiency in determining the optimal parameters for NVCA. The preliminary results obtained in this study suggest SED could be more efficient than FSIM in identifying the best trade off between noise reduction and edge preservation, and could be also used to determine the optimal parameters of other denoising algorithms.
Automated multi sensor color video fusion for nighttime video surveillance
Venue: The IEEE symposium on Computers and Communications
Year: 2010

In this paper, we present an automated color transfer based video fusion method to attain real time color night vision capability for night time video surveillance. We utilize simple RGB Color transfer technique to fused pseudo colored video frames without conversion to any uncorrelated color space. We investigated that final color fusion results greatly depend on the selection of target color Image. Therefore, rather than using any arbitrary target color image based on mere general visual anticipation, we have automated target color image selection using structural similarity and color saturation. We further apply color enhancement to improve final appearance of color fused images. Subjective and objective quality evaluations greatly indicate the effectiveness of our color video fusion method for nighttime video surveillance applications.
Can Project Managers' Emotional Intelligence Contribute to the Success of Construction Projects?
Year: 2019

Today, the challenges faced by a construction project manager are to improve the level of efficiency and overall productivity levels while at the same time maintaining harmonious relationships with stakeholders. They need to be able to communicate and interact at an all level and know how to use tools and methods to improve outcomes. Although Emotional Intelligence is an individual capability concerning a project team, it can provide a level of motivation and energy for the entire project team to detect and avoid any sign of project failure. To be aligned appropriately, a good project manager should be able to evaluate and track potential risks and make clear plans and manage the project. This article examines Emotional Intelligence as one of the drivers for the project manager's achievement and shows how to combine Emotional Intelligence and effective project management. If Emotional Intelligence focuses mainly on the level of communication within management staff, the ultimate goal of project management is to avoid defects during and after project, efficient time management, overall cost controlled, and comprehensive project planning structured thoroughly into achieving a successful project. The question is, in the end, "Can project managers' Emotional intelligence contributes to the success of construction projects?" By combining several critical aspects of Emotional Intelligence, this paper proposes a more comprehensive approach to how construction project management is managed in the future.
Evaluation of early age performance of reinforced concrete pile cap
Year: 2017

The acceleration of construction in terms of early formwork removal or premature loading has a critical effect on the total construction cost. In order to perform the acceleration correctly, good decisions must be made. This paper provides a simple structural analysis method based on the strut and tie modelling which helps to make such decisions. The strength and stiffness development of concrete at early age is reviewed in the most relevant construction codes and the most suitable formulations are recommended. Then, the strength and stiffness development functions are introduced into the strut and tie model and the two dimensional or three dimensional structural analysis can be performed. The effect of creep is also included in terms of the creep coefficient so that the long term consequences of the accelerated construction can be also evaluated. The proposed method is demonstrated in an example of a reinforced concrete pile cap. The method is useful either for engineering practice or for a quick rough verification of complex numerical simulations of hardening concrete when prematurely loaded.

Crucial role of the REFe2 intergranular phase on corrosion resistance of Nd La Ce Fe B sintered magnets
Year: 2018

Poor corrosion resistance is one major concern of RE2Fe14B type (RE, rare earth) sintered magnets due to the large electrode potential difference between the ferromagnetic matrix phase and the RE rich intergranular phase. The phase constituent within the intergranular region of high cost performance Nd La Ce Fe B magnets, however varies with the La/Ce substitution level, and extra REFe2 phase forms over a critical La/Ce content. In this work, we performed a comparative study of two magnets prepared by single main phase (SMP, sintering the Nd La Ce Fe B powders free of REFe2 phase) or by binary main phase (BMP, sintering the mixture of Nd Fe B and Nd La Ce Fe B powders containing REFe2 phase) approaches to reveal the role of REFe2 phase on the corrosion resistance. The results show that the BMP magnet with additional REFe2 intergranular phase exhibits much better corrosion resistance against both hot/humid and saline environments than the SMP one having merely conventional RE rich intergranular phase. It is attributed to that the REFe2 phase with higher electrode potential than RE rich phase stabilizes the intergranular regions and lowers the driving force for electrochemical corrosion. Besides, REFe2 phase that locates mainly at the triple junctions suppresses the corrosion propagation and blocks the subsequent dissolution of RE2Fe14B grains. The Nd La Ce Fe B BMP magnets with improved corrosion resistance as well as the formerly reported superior magnetic performance to SMP ones are appealing for practical applications.
One Year Patient Outcomes for Robotic Arm Assisted versus Manual Total Knee Arthroplasty.
Venue: The journal of knee surgery
Year: 2019

Although there are many studies on the alignment advantages when using the robotic arm assisted (RAA) system for total knee arthroplasty (TKA) there have been questions regarding patient reported outcomes. Therefore, the purpose of this study was to use this index to compare: (1) total, (2) physical function, and (3) pain scores for manual versus RAA patients. We compared 53 consecutive RAA to 53 consecutive manual TKAs. No differences in preoperative scores were found between the cohorts. Patients were administered a modified Western Ontario and McMaster Universities Osteoarthritis Index satisfaction survey preoperatively and at 1 year postoperatively. The results were broken down to: (1) total, (2) physical function, and (3) pain scores. Univariate analysis with independent samples t tests was used to compare 1 year postoperative scores. Multivariate models with stepwise backward linear regression were utilized to evaluate the associations between scores and surgical technique, age, sex, as well as body mass index (BMI) Statistical analyses were performed with a p 0.05 to determine significance. The RAA cohort had significantly improved mean total (6 6 vs. 9 8 points, p 0.03) and physical function scores (4 4 vs. 6 5 points, p 0.02) when compared with the manual cohort. The mean pain score for the RAA cohort (2 3 points [range, 0 14 points] was also lower than that for the manual cohort (3 4 points [range, 0 11 points] (p 0.06) On backward linear regression analyses, RAA was found to be significantly associated with more improved total (b coefficient [b] 0.208, standard error [SE] 1.401, p 0.05) function (b 0.216, SE 0.829, p 0.05) and pain scores (b 0.181, SE 0.623, p 0.063) The RAA technique was found to have the strongest association with improved scores when compared with age, gender, and BMI. This study suggests that RAA patients may have short term improvements at minimum 1 year postoperatively. However, longer term follow up with greater sample sizes is needed to further validate these results.
Carbon Based Metal Free Electrocatalysis for Energy Conversion, Energy Storage, and Environmental Protection
Venue: Electrochemical Energy Reviews
Year: 2018

Carbon based metal free catalysts possess desirable properties such as high earth abundance, low cost, high electrical conductivity, structural tunability, good selectivity, strong stability in acidic/alkaline conditions, and environmental friendliness. Because of these properties, these catalysts have recently received increasing attention in energy and environmental applications. Subsequently, various carbon based electrocatalysts have been developed to replace noble metal catalysts for low cost renewable generation and storage of clean energy and environmental protection through metal free electrocatalysis. This article provides an up to date review of this rapidly developing field by critically assessing recent advances in the mechanistic understanding, structure design, and material/device fabrication of metal free carbon based electrocatalysts for clean energy conversion/storage and environmental protection, along with discussions on current challenges and perspectives.
Female Bias in Systemic Lupus Erythematosus is Associated with the Differential Expression of X Linked Toll Like Receptor 8
Venue: Front. Immunol.
Year: 2015

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by the production of anti nuclear antibodies. SLE is one of many autoimmune disorders that have a strong gender bias, with 70 90% of SLE patients being female. Several explanations have been postulated to account for the severity of autoimmune diseases in females, including hormonal, microbiota, and gene dosage differences. X linked toll like receptors (TLRs) have recently been implicated in disease progression in females. Our previous studies using the 564Igi mouse model of SLE on a Tlr7 and Tlr9 double knockout background showed that the presence of Tlr8 on both X chromosomes was required for the production of IgG autoantibodies, Ifn I expression and granulopoiesis in females. Here, we show the results of our investigation into the role of Tlr8 expression in SLE pathogenesis in 564Igi females. Female mice have an increase in serum pathogenic anti RNA IgG2a and IgG2b autoantibodies. 564Igi mice have also been shown to have an increase in neutrophils in vivo, which are major contributors to Ifn a expression. Here, we show that neutrophils from C57BL/6 mice express Ifn a in response to 564 immune complexes and TLR8 activation. Bone marrow derived macrophages from 564Igi females have a significant increase in Tlr8 expression compared to male derived cells, and RNA fluorescence in situ hybridization data suggest that Tlr8 may escape X inactivation in female derived macrophages. These results propose a model by which females may be more susceptible to SLE pathogenesis due to inefficient inactivation of Tlr8.
A PSICOLOGIA PODE SER UMA CIENCIA DA MENTE
Year: 2012

Muitos psicologos, como os filosofos antes deles, olharam dentro de si mesmos para a explicacao de seus comportamentos. Eles sentiram [felt] sentimentos e observaram processos mentais por meio da introspeccao. Entretanto, a introspeccao nunca foi muito satisfatoria. Os filosofos reconheceram sua inadequacao, embora insistindo que esse e, todavia, o unico meio de autoconhecimento. Os psicologos outrora ja tentaram aprimora la pelo uso de observadores treinados e dos instrumentos de metal [brass instruments] sobre os quais Willian James teve opiniao desfavoravel. A introspeccao ja nao e mais muito usada. Psicologos cognitivistas podem ver representacoes e podem ate argumentar que elas sao as unicas coisas que podem ser vistas, mas eles nao afirmam que veem a si mesmos processando as. Ao contrario, como os psicanalistas, que enfrentam o mesmo problema com processos que nao podem ser vistos porque sao inconscientes, voltaram se para a teoria. Teorias, contudo, precisam de confirmacao, e por isso muitos se voltaram para a ciencia do cerebro, em que se pode dizer que os processos sao inspecionados [inspected] em vez de serem observados instrospectados [introspected].3 Se a mente e "o que cerebro faz" o cerebro pode ser estudado como qualquer outro orgao. Consequentemente, entao, a ciencia do cerebro deveria dizer nos o que significa construir uma representacao da realidade, armazenar uma representacao na memoria, converter uma intencao em acao, sentir alegria ou tristeza, tirar uma conclusao logica, e assim por diante.
Word level Textual Adversarial Attacking as Combinatorial Optimization
Venue: ACL
Year: 2020

Adversarial attacks are carried out to reveal the vulnerability of deep neural networks. Textual adversarial attacking is challenging because text is discrete and a small perturbation can bring significant change to the original input. Word level attacking, which can be regarded as a combinatorial optimization problem, is a well studied class of textual attack methods. However, existing word level attack models are far from perfect, largely because unsuitable search space reduction methods and inefficient optimization algorithms are employed. In this paper, we propose a novel attack model, which incorporates the sememe based word substitution method and particle swarm optimization based search algorithm to solve the two problems separately. We conduct exhaustive experiments to evaluate our attack model by attacking BiLSTM and BERT on three benchmark datasets. Experimental results demonstrate that our model consistently achieves much higher attack success rates and crafts more high quality adversarial examples as compared to baseline methods. Also, further experiments show our model has higher transferability and can bring more robustness enhancement to victim models by adversarial training. All the code and data of this paper can be obtained on https:/github.com/thunlp/SememePSO Attack.
A Study on Influencing Factors of Low Frequency Sound Wave Fire Extinguisher
Venue: 2020 8th International Conference on Power Electronics Systems and Applications (PESA)
Year: 2020

In daily life, fire accidents will happen at any time, but the way to put the fires off has not changed. Most of them are put out with water or chemicals, which cause secondary pollution to the surrounding environment and even cause irreversible damage to some items. The fire is very destructive, and people are paying more attention to fire prevention, so many places have prepared fire extinguishers. Public fire extinguishers include dry powder fire extinguishers, carbon dioxide fire extinguishers, foam fire extinguishers, but they will face some difficult problems in the application. Dry powder fire extinguishers and foam fire extinguishers will pollute the surrounding environment of the fire and they are not easy to restore to the previous state, beside, the wrong operation of carbon dioxide fire extinguishers in a confined space will also cause harm to the health of people in the fire scene. The new low frequency acoustic fire extinguisher is proposed in this article. It could eliminate fire hazards and avoid secondary damage to the place. This type of fire extinguisher provides the least destructive and cleanest fire fighting method.
Simulation of a Novel Configuration for Luminescent Solar Concentrator Photovoltaic Devices Using Bifacial Silicon Solar Cells
Year: 2020

In this study, a novel configuration for luminescent solar concentrator photovoltaic (LSC PV) devices is presented, with vertically placed bifacial PV solar cells made of mono crystalline silicon (mono c Si) This LSC PV device comprises multiple rectangular cuboid lightguides, made of poly (methyl methacrylate) (PMMA) containing Lumogen dyes, in particular, either Lumogen red 305 or orange 240. The bifacial solar cells are located in between these lightguide cubes and can, therefore, receive irradiance at both of their surfaces. The main aim of this study is to theoretically determine the power conversion efficiency (PCE) of five differently configured LSC PV devices. For this purpose, Monte Carlo ray tracing simulations were executed to analyze the irradiance at receiving PV cell surfaces, as well as the optical performance of these LSC PV devices. Five different LSC PV devices, with different geometries and varying dye concentrations, were modeled. To maximize the device efficiency, the bifacial cells were also attached to the back side of the lightguides. The ray tracing simulations resulted in a maximum efficiency of 16.9% under standard test conditions (STC) for a 15 x 15 cm2 LSC PV device, consisting of nine rectangular cuboid 5 x 5 x 1 cm3 PMMA lightguides with 5 ppm orange 240 dye, with 12 vertically positioned 5 x 1 cm2 bifacial cells in between the lightguides and nine 5 x 5 cm2 PV cells attached to the back of the device. If the cells are not applied to the back of this LSC PV device configuration, the maximum PCE will be 2.9% (under STC) where the LSC PV device consists of 25 cubical 1 x 1 x 1 cm3 PMMA lightguides with 110 ppm red 305 dye and 40 vertically oriented bifacial PV cells of 1 x 1 cm2 in between the lightguides. These results show the vast future potential for LSC PV technologies, with a higher performance and efficiency than the common threshold PCE for LSC PV devices of 10%
