Overcoming Path Dependency with Entrepreneurial Self Efficacy
Year: 2013

Path dependency is an unfortunate behavior (Choi, 2011) Although researchers acknowledge the omnipresent nature of path dependent behavior (Gruber, 2010) especially in innovation processes and organizational developments (Mishina et al. 2012; Thrane et al. 2010) little research on understanding path dependency in the context of entrepreneurial and managerial decision making was carried out so far. Therefore, understanding antecedents and environmental conditions is the main focus of our research. This paper studies path dependent behavior when selecting and combining means to solve entrepreneurial and managerial problems under different conditions. We focus on entrepreneurial self efficacy (McGee et al. 2009) as its subdimensions can be utilized to distinguish entrepreneurs from managers (Chen et al. 1998) To account for several environmental conditions, we designed a unique experimental questionnaire inducing four specific scenarios in temporal order. We hypothesize that path dependency can be burst in specific situations.
Exfoliation and functionalization of a zirconium phosphate in one pot for waterborne epoxy coatings with enhanced anticorrosion performance
Year: 2020

Having high aspect ratio and excellent gas barrier property, two dimensional a zirconium phosphate nanosheets (a ZrP) are one of the promising anticorrosive nanofillers. In this work, under mild conditions, layered a ZrP were effectively exfoliated by Tris buffer solution and functionalized by situ polymerization of polydopamine (PDA) in one pot. And then the functionalized a ZrP (f ZrP) were introduced into waterborne epoxy (WEP) coatings that were applied on the mild steel for electrochemical corrosion tests. Results of TEM, XRD and AFM reveal that a ZrP are successfully exfoliated with an interlayer space of 1.72 nm and a thickness of 0.78 nm. Characterizations of FTIR spectra, TEM image and EDS mapping confirm that a ZrP are decorated by PDA. With PDA decoration, f ZrP gain a better compatibility with WEP than pristine a ZrP do, leading to a homogeneous distribution in the polymer matrix. And the exfoliation by Tris buffer provides f ZrP with high aspect ratio, which is beneficial for f ZrP/WEP to fight against the permeation of corrosive mediums. Therefore, after 15 day immersion in 3.5 wt% NaCl solution, the f ZrP/WEP composite coatings show high value of |Z0.01Hz| (1.90 x 107 O*cm2) which is about one order of magnitude over that of blank WEP coatings (2.33 x 106 O*cm2)
Multi Objective Electric Truck Path Optimization Model with Time Window
Venue: 2019 4th International Conference on Control, Robotics and Cybernetics (CRC)
Year: 2019

Aiming at the problem of electric truck path, an electric truck path optimization model with time window is proposed. The model considers the relationship between the speed of the electric truck, the load of the cargo, and the energy consumption, minimizing the total power consumption of the distribution center and the total advance or delay time. At the same time, simulation experiment is carried out by using the grey wolf algorithm. The comparison between the simulation results and the genetic algorithm shows that the grey wolf algorithm can solve the vehicle path planning with time window easily and effectively. It has better convergence and accuracy and is an effective way to solve such path optimization problems.
"I forgot that I'm disabled" interactions and sociability of teenagers with physical disabilities that practice sports]
Venue: Cadernos de saude publica
Year: 2020

The article analyzes the meanings assigned by teenagers with disabilities to experiences participating in group sports. The qualitative study, based on comprehensive critical analysis, drew on semi structured interviews with teens with physical disability. The results of the analysis pointed to three thematic lines: (1) the body, (2) sociability and group interactions, and (3) interactions outside the group. The sports setting features groups as a space for sociability, evoking autonomy, self esteem, and performance. Reconfiguration of the body with disability approached the able bodied ideal of the able body, which also shaped the challenges in interactions outside the group. In conclusion, the meanings legitimize hegemonic models of masculinity and femininity, and the able bodied ideal was mobilized as a common system for relevance among teenagers with physical disability that practice sports.

Enhanced c Fos expression in superior colliculus, paraventricular thalamus and septum during learning of cue reward association
Venue: Neuroscience
Year: 2010

Reward mediated associative learning is important for recognizing the significance of environmental cues. Such learning involves convergence of multimodal sensory inputs with circuits involved in affective and memory processes. Dopamine dependent plasticity in the striatum plays a pivotal role, but the wider circuits engaged in cue reward association are poorly understood. To identify candidate structures that may be of particular interest for further detailed electrophysiological and functional analysis, we quantified c Fos expression in a selection of brain structures. c Fos is a well known marker of cell activation with additional potential importance for synaptic plasticity. We compared c Fos expression between animals exposed to 100 pairings of a novel conditioned stimulus with a subsequent reward, and control animals exposed to the same number of cues and rewards, but where the cues and rewards occurred at random with respect to each other. We found significant increases in c Fos expression in the superior colliculus in the group exposed to cue reward pairing. This is consistent with previous recordings in conscious animals, showing modulation of phasic visual responses of single collicular neurons depending on their association with reward. Further, the data also suggest the possibility that the thalamic paraventricular nucleus and septal nuclei may be selectively activated during cue reward association learning. Little is known of the neurophysiological responses in these structures during such tasks, so the present results suggest they would be targets of interest for future single neuron recording experiments, designed to confirm whether the neurons show learning specific modulation.
Hygrothermal aging of flip chip assembled MOEMS
Year: 2017

Low cost and miniaturized solutions for assembly of optical microelectromechanical systems (MOEMS) are critical for increased exploitation of optical sensors and devices in consumer applications. Examples of applications based on optical sensors and devices already near or on the market are auto focus lenses and pico projectors for mobile phones, physiology measurement units for wearables, and high bandwidth free space optical communication links for our homes. In addition, extensive use of photonic integrated circuits is predicted to be mandatory in order to answer to the future needs for high data transfer rates in data centers. However, the main limitation for several of these applications is the complexity, the related cost of assembly, and the unknown reliability of several lower cost assembly solutions; polymer based solutions are e.g. prone to fail particularly fast in humid and warm conditions. In this work, a part of a European project called Lab4MEMS II, we study the feasibility of reducing the
Convergence Analysis of ISO/IEC 12207 and CMMI DEV: Complementary Result from Systematic Literature Review
Venue: CLEI Electron. J.
Year: 2017

The organizations and people are demanding more and better software products and services, which implies adequate processes for its development. In the context of the software industry, there are two models, the CMMI DEV and ISO/IEC 12207 that are influencing it. Though, they are evolving separately, recurrently they have been compared to determine its coverage (in both directions) In this study is analyzed the results of those comparisons (partials and completed) to determine if the models ISO/IEC 12207 and CMMI DEV converge at processes level. This study identified eight articles where the comparison is carried out between ISO/IEC 12207 and CMMI DEV. The results show that technique most used is the mapping comparisons between the models and according to the analyzed studies is not possible to determine whether there is convergence in the time. However, we found some items and criterions for use in comparisons.
Post transcriptional gene regulation by mRNA modifications
Venue: Nature Reviews Molecular Cell Biology
Year: 2017

The recent discovery of reversible mRNA methylation has opened a new realm of post transcriptional gene regulation in eukaryotes. The identification and functional characterization of proteins that specifically recognize RNA N6 methyladenosine (m6A) unveiled it as a modification that cells utilize to accelerate mRNA metabolism and translation. N6 adenosine methylation directs mRNAs to distinct fates by grouping them for differential processing, translation and decay in processes such as cell differentiation, embryonic development and stress responses. Other mRNA modifications, including N1 methyladenosine (m1A) 5 methylcytosine (m5C) and pseudouridine, together with m6A form the epitranscriptome and collectively code a new layer of information that controls protein synthesis.
Barriers to organizational adoption of EMR systems in family physician practices: A mixed methods study in Canada
Venue: Int. J. Medical Informatics
Year: 2014

EMR system can provide three main types of benefits: it can solve the logistical organization problems associated with paper systems; it can improve the quality of professionals' clinical decisions; and it can improve physicians' return on their practices by reducing the cost of managing clinical information. According to the 2012 Commonwealth Fund International Health Policy Survey, Canada ranked 10th out of 11 countries in terms of family physicians' adoption of EMR systems. Our main purpose is to investigate the reasons why so many primary care medical practices in this country have not decided to invest in these systems yet.  To achieve our main objective, a mixed methods study was performed. We first conducted a Delphi study with a panel of 21 experts made up of general practitioners with extensive professional experience and a very good understanding of the issues surrounding the introduction of health IT in private medical practices. As a second step, we collected and analyzed data from a large questionnaire survey of family physicians working in medical practices without EMR systems (n 431) RESULTS The Delphi study reveals that private medical practices are hindered by four types of barriers when faced with the initial decision to invest in an EMR system, namely, behavioral, cognitive or knowledge based, economic, and technological. Survey findings then indicate that the key challenges preventing private medical practices from investing in an EMR system are mainly related to economic and knowledge barriers. Surprisingly, we also found a cluster of medical practices which, although they have not invested in an EMR system, perceive no such barriers to adoption.  A thorough understanding of the barriers faced by family physician practices in adopting an EMR system would help governments and other key stakeholders target policies and measures in support of medical practices. The "one size fits all" approach to such policies and measures is clearly inappropriate, given this study's findings that many medical practices face practically no barriers to EMR adoption, and that others differ markedly as to the type of barriers faced, be they mostly "soft" such as knowledge barriers or "hard" such as economic barriers.
Quantum Byzantine Agreement via Hardy correlations and entanglement swapping
Venue: ArXiv
Year: 2014

We present a device independent quantum scheme for the Byzantine generals problem. The protocol is for three parties. Party $C$ is to send two identical one bit messages to parties $A$ and $B$ The receivers $A$ and $B$ may exchange two one bit messages informing the other party on the message received from $C$ A bit flipping error in one of the transmissions does not allow the receiving parties to establish what was the message of $C$ Our quantum protocol is based on Hardy's argument, which uses a set of conditions impossible for classical systems, but satisfied by predictions for a unique two qubit state. The scheme has the feature that if the messages of the Byzantine protocol are readable (that is give an unambiguous bit value for any of the receivers) then any error by $C$ (cheating by one of the commanding generals) is impossible. $A$ and $B$ do not have to exchange protocol messages to be sure of this.
The Impact of Government Debt, Expenditure and Taxes on Aggregate Investment and Productivity Growth
Year: 2016

In this paper we evaluate empirically the impact of fiscal policy on two key determinants of long term growth, i.e. private investment and productivity growth. We mostly focus on a panel of 20 OECD economies from 1970 to 2009, although we also present some estimates based on data for 80 developing economies. Our findings suggest that high public debt adversely affects both aggregate investment spending and productivity growth, through distortions related to the size of the public sector. We also find weak evidence of some nonlinear effects on productivity, with government debt becoming more detrimental when above 85 90% of GDP in advanded economies.

Gold nanoparticle mediated bubbles in cancer nanotechnology.
Venue: Journal of controlled release official journal of the Controlled Release Society
Year: 2020

Microbubbles (MBs) have been extensively investigated in the field of biomedicine for the past few decades. Ultrasound and laser are the most frequently used sources of energy to produce MBs. Traditional acoustic methods induce MBs with poor localized areas of action. A high level of energy is required to generate MBs through the focused continuous laser, which can be harmful to healthy tissues. As an alternative, plasmonic light responsive nanoparticles, such as gold nanoparticles (AuNPs) are preferably used with continuous laser to decrease the energy threshold and reduce the bubbles area of action. It is also well known that the utilization of the pulsed lasers instead of the continuous lasers decreases the needed AuNPs doses as well as laser power threshold. When well confined bubbles are generated in biological environments, they play their own unique mechanical and optical roles. The collapse of a bubble can mechanically affect its surrounding area. Such a capability can be used for cargo delivery to cancer cells and cell surgery, destruction, and transfection. Moreover, the excellent ability of light scattering makes the bubbles suitable for cancer imaging. This review firstly provides an overview of the fundamental aspects of AuNPs mediated bubbles and then their emerging applications in the field of cancer nanotechnology will be reviewed. Although the pre clinical studies on the AuNP mediated bubbles have shown promising data, it seems that this technique would not be applicable to every kind of cancer. The clinical application of this technique may basically be limited to the good accessible lesions like the superficial, intracavity and intraluminal tumors. The other essential challenges against the clinical translation of AuNP mediated bubbles are also discussed.
Isolation of CD4+ T cells and Analysis of Circulating T follicular Helper (cTfh) Cell Subsets from Peripheral Blood Using 6 color Flow Cytometry.
Venue: Journal of visualized experiments JoVE
Year: 2019

Aberrant T follicular helper (Tfh) cell activity is detectable in autoimmune conditions and their presence is associated with clinical outcomes when the lymph node microenvironment in B cell non Hodgkin's lymphoma is analyzed. Subsets of circulating T follicular helper cells (cTfh) the circulating memory compartment of Tfh cells in the blood, are also perturbed in disease and therefore represent potential novel predictive biomarkers. Peripheral blood based testing is advantageous because it is relatively non invasive and allows simple serial monitoring.This article describes a method for isolating CD4+ T cells from human blood, and further analysis by flow cytometry to enumerate cTfh cells and the proportions of their various subsets (cTfhPD 1 /hi, cTfh1,2,17 and cTfh1/17) The level of these subsets was then compared between normal subjects and patients with lymphoma. We found that the method was robust enough to obtain reliable results from routinely collected patient material. The technique we describe for the analysis can be easily adapted to cell sorting and downstream applications such as RT PCR.
Three dimensional (3D) printed tablets using ethyl cellulose and hydroxypropyl cellulose to achieve zero order sustained release profile
Venue: Cellulose
Year: 2019

The main objective of this study was to investigate the potential of coupling hot melt extrusion (HME) and 3D printing in order to design drug containing matrix tablets for the purpose of achieving zero order release. The effect of the blend ratio of ethyl cellulose (EC) and hydroxypropyl cellulose (HPC) carbamazepine (CBZ) as a model drug and triethyl citrate (TEC) on the mechanical and printability properties of extruded filaments was investigated. Filament formulation containing CBZ, EC and HPC (3, 64.7 and 32.3% w/w, respectively) and 20% w/w of TEC (by weight on the dry powder) showed optimum mechanical and printability properties and subsequently was printed into tablets (370 mg, 13 mm diameter, 3.5 mm thickness, cylinder shaped) at 187 degC. The printed tablets showed good uniformity in drug content and appropriate mechanical properties. The optimum filament showed first order drug release pattern, while the 3D printed tablets showed zero order drug release and slower drug release rate than the optimum filament. Overall, we have demonstrated that zero order release tablets can be prepared from a 2:1 ratio of EC to HPC, by combination of HME and 3D printing technologies with the capability of reducing dose frequency and adverse effects of drugs.
Wearable Wheelchair Mobility Performance Measurement in Basketball, Rugby, and Tennis: Lessons for Classification and Training
Venue: Sensors
Year: 2020

Athlete impairment level is an important factor in wheelchair mobility performance (WMP) in sports. Classification systems, aimed to compensate impairment level effects on performance, vary between sports. Improved understanding of resemblances and differences in WMP between sports could aid in optimizing the classification methodology. Furthermore, increased performance insight could be applied in training and wheelchair optimization. The wearable sensor based wheelchair mobility performance monitor (WMPM) was used to measure WMP of wheelchair basketball, rugby and tennis athletes of (inter )national level during match play. As hypothesized, wheelchair basketball athletes show the highest average WMP levels and wheelchair rugby the lowest, whereas wheelchair tennis athletes range in between for most outcomes. Based on WMP profiles, wheelchair basketball requires the highest performance intensity, whereas in wheelchair tennis, maneuverability is the key performance factor. In wheelchair rugby, WMP levels show the highest variation comparable to the high variation in athletes' impairment levels. These insights could be used to direct classification and training guidelines, with more emphasis on intensity for wheelchair basketball, focus on maneuverability for wheelchair tennis and impairment level based training programs for wheelchair rugby. Wearable technology use seems a prerequisite for further development of wheelchair sports, on the sports level (classification) and on individual level (training and wheelchair configuration)
