Granzyme B in skin aging, injury and repair
Creators: name: Hiebert, Paul Ryan
Publisher: name: University of British Columbia
Year: 2013

description: Granzyme B (GzmB) is a serine protease that can be released into the extracellular spaces by immune cells during chronic inflammation where it is capable of degrading several components of the extracellular matrix (ECM). Several chronic inflammatory skin diseases have demonstrated elevated levels of GzmB however the exact role of GzmB in the skin remains poorly understood. Apolipoprotein E (ApoE) is a protein highly expressed in the skin, where it can regulate inflammation through its anti-oxidative and anti-inflammatory properties. Mice deficient in ApoE develop an inflammatory skin phenotype when fed a high fat diet indicative of premature aging featuring ECM remodeling, hair graying, hair loss and frailty. I therefore hypothesized that GzmB contributes to skin aging, injury and impaired healing in ApoE knockout (ApoE-KO) mice through the degradation of ECM proteins. In the present dissertation, I identified the high fat diet-fed ApoE-KO mouse as a model that displays several characteristic features of skin aging including skin thinning and collagen disorganization. Further investigations also identified that high fat diet-fed ApoE-KO mice show defects in cutaneous wound healing such as delayed wound closure, reduced contraction and altered collagen content. These changes became worse with age and high fat diet. To test the role of GzmB in this process, GzmB/ApoE double knockout (DKO) mice were generated. These DKO mice were protected from skin thinning and collagen disorganization even when fed a high fat diet, suggesting that GzmB plays a role in ECM remodeling during aging of the skin in ApoE-KO mice. Further investigation revealed that GzmB-mediated degradation of the proteoglycan decorin is likely to be a key mechanism by which GzmB contributes to collagen disorganization and skin aging in ApoE-KO mice. Furthermore, DKO mice showed improved wound healing compared to ApoEKO mice featuring faster wound closure, increased contraction and reduced fibronectin degradation. In vitro cleavage assays revealed that fibronectin fragments generated by GzmB matched those identified in non-healing ApoE-KO mouse wounds. In summary, my findings suggest that extracellular GzmB contributes to skin aging and impaired healing in ApoE-KO mouse skin through the degradation of ECM components such as decorin and fibronectin.

description: Background: People with Type 2 diabetes (T2DM) face numerous financial barriers to diabetes self-management. An example of such a barrier is household food insecurity, or the inadequate or insecure access to food due to financial constraints. To address this issue, we designed FoodRx, a 12-month weekly healthy food incentive ($10.50/week/household member) program. Exploring users’ acceptability of FoodRx before incentive use (i.e., prospective acceptability) can provide insights into issues with low enrolment and help design programs that are better received by the target population. Objectives: To explore intended users’ prospective acceptability of the FoodRx design and delivery and identify factors that influence users’ prospective acceptability.Method: I used a qualitative descriptive approach and purposively recruited adults who did or did not want to use FoodRx. Participants received food incentive training and then completed a semi-structured interview guided by the Theoretical Framework of Acceptability. Interview transcripts and observational field notes of the training were analyzed using differential qualitative analysis guided by the socio-ecological model. Results: People who wanted to participate in FoodRx (n=10) perceived the incentive to be more acceptable than those who did not want to use it (n=5). I identified four themes that captured intrapersonal and contextual factors that influenced users’ prospective acceptability of FoodRx. The first theme included intrapersonal factors, including three subthemes (confidence, attitudes, and beliefs). Participants' prospective acceptability of FoodRx and the intrapersonal factors influencing acceptability were contextualized by the second, third, and fourth themes: ii) the shopping routines and roles of individuals in their social networks (social context), iii) access to and experience with food retailers (food retail context), iv) income and food access support to navigate the cost of living (economic context). Differences between the two subgroups of participants stemmed from gender and age-related experiences of household food insecurity and poverty.Conclusion: Prospective acceptability of FoodRx was influenced by individuals' gender- and age-related differences in intrapersonal factors and social, food retail, and economic contexts. Future healthy food prescription programs should consider contextual factors to better understand who participates and make relevant changes to design and delivery to improve program acceptability.

description: Nel volume qui recensito George Steiner si interroga sulla legittimità della trasmissione della tradizione filosofica e letteraria occidentale. L’indagine si concentra sul ruolo che la cultura ha svolto nell’evoluzione umana dalla Rivoluzione francese ai giorni nostri, esaminando tanto l’insopprimibile tendenza alla barbarie dell’uomo occidentale quanto la sua costante volontà di ricerca e di sviluppo intellettuale. Gli interrogativi posti sul compito che la cultura dovrebbe assolvere dopo le tragedie della prima metà del novecento – in particolare quella dell’Olocausto – sono, in questo senso, quanto mai attuali e pressanti.

description: From the holographic renormalizationg group viewpoint, while the scale transformation plays a primary role in the duality by providing the extra dimension, the special conformal transformation seems to only play a secondary role. We, however, claim that the space-time diffeomorphism is crucially related to the latter. For its demonstration, we study the holographic renormalization group flow of a foliation preserving diffeomophic theory of gravity (a.k.a. space-time flipped Horava gravity). We find that the dual field theory, if any, is only scale invariant but not conformal invariant. In particular, we show that the holographic trace anomaly in four-dimension predicts the Ricci scalar squared term that would be incompatible with the Wess-Zumino consistency condition if it were conformal. This illustrates how the foliation preserving diffeomophic theory of gravity could be inconsistent with a theorem of the dual unitary quantum field theory.

Tolerating intermittent hardware errors : characterization, diagnosis and recovery
Creators: name: Rashid, Layali
Publisher: name: University of British Columbia
Year: 2013

description: Over three decades of continuous scaling in CMOS technology has led to tremendous improvements in processor performance. At the same time, the scaling has led to an increase in the frequency of hardware errors due to high process variations, extreme operating conditions and manufacturing defects. Recent studies have found that 40% of the processor failures in real-world machines are due to intermittent hardware errors. Intermittent hardware errors are non-deterministic bursts of errors that occur in the same physical location. Intermittent errors have characteristics that are different from transient and permanent errors, which makes it challenging to devise efficient fault tolerance techniques for them. In this dissertation, we characterize the impact of intermittent hardware faults on programs using fault injection experiments at the micro-architecture level. We find that intermittent errors are likely to generate software visible effects when they occur. Based on our characterization results, we build intermittent error tolerance techniques with focus on error diagnosis and recovery. We first evaluate the impact of different intermittent error recovery scenarios on a processor's performance and availability. We then propose DIEBA (Diagnose Intermittent hardware Errors in microprocessors by Backtracing Application), a software-based technique to diagnose the fault-prone functional units in a processor.

description: We study a Langevin equation describing the Brownian motion of an object subjected to a viscous drag, an external constant force, and a solid friction force of the Coulomb type. In a previous work [H. Touchette, E. Van der Straeten, W. Just, J. Phys. A: Math. Theor. 43, 445002, 2010], we have presented the exact solution of the velocity propagator of this equation based on a spectral decomposition of the corresponding Fokker-Planck equation. Here, we present an alternative, exact solution based on the Laplace transform of this equation, which has the advantage of being expressed in closed form. From this solution, we also obtain closed-form expressions for the Laplace transform of the velocity autocorrelation function and for the power spectrum, i.e., the Fourier transform of the autocorrelation function. The behavior of the power spectrum as a function of the dry friction force and external forcing shows a clear crossover between stick and slip regimes known to occur in the presence of solid friction.

description: Using the effective-one-body (EOB) formalism and a time-domain Teukolsky code, we generate inspiral, merger, and ringdown waveforms in the small mass-ratio limit. We use EOB inspiral and plunge trajectories to build the Teukolsky equation source term, and compute full coalescence waveforms for a range of black hole spins. By comparing EOB waveforms that were recently developed for comparable mass binary black holes to these Teukolsky waveforms, we improve the EOB model for the (2,2), (2,1), (3,3), and (4,4) modes. Our results can be used to quickly and accurately extract useful information about merger waves for binaries with spin, and should be useful for improving analytic models of such binaries.

description: A lab scale study was carried out to investigate the electrocoagulation (EC) process for the treatment of oil-sands produced water. The target contaminant was silica, along with hardness causing ions calcium and magnesium. The viability of continuous treatment of produced water by EC was investigated for the first time, using both DC and polarity reversal (PR) operation. The performance of EC for treatment of both synthetic and field samples of produced water was evaluated under a range of charge loading (i.e., electrical charge passed per unit volume of water treated), flowrate, electrode area, and current density in a continuous flow EC treatment system. The results revealed that using iron or aluminum EC can effectively remove silica and other contaminants from synthetic and real produce water, with higher removal achieved using aluminum electrodes. In DC operation removal of contaminants increased with the charge loading, Al-EC was found to remove more than 90% of silica from a synthetic produced water at a charge loading of 1500 C/L and 8 mA cm-2 current density at all flow rates. Under the same operating conditions Fe-EC was found to remove from 56% to 81% of the silica as the flow rate was increased. The use of a hybrid combination of alternating Al and Fe electrodes for continuous EC treatment of produced water was investigated for the first time. The silica removal achieved with this system was 96% silica with an energy consumption of 1.53 kWh/m3 using periodic polarity reversal every 10 min. A novel concept of asymmetric polarity reversal with this combination of of Al and Fe electrodes was also investigated. Seven double sided electrodes (3 Fe and 4 Al) were immersed in the solution of synthetic produced water. Under these operating conditions (10 min & 30 sec) asymmetric polarity reversal time was able to achieve lower cell voltage (and hence energy consumption), and less electrode fouling were obtained, with a high silica removal of more than 95% from synthetic produced water, with an estimated operating cost of C$0.94/m3 at a charge loading of 2000 C/L, and a current density of 8 mA cm-2.

description: The main goal of this study is to explore the integration of Calgary Framework CALF20, [Zn2(1,2,4-triazolate)2(oxalate)], that was developed in Dr. Shimzu’s lab in three catalytic conversion processes. Each process was implemented in this project as a separate objective. Chapter 3 included developing an integrated device at Dr. Kibria’s lab, wherein MOF-based porous materials served as CO? concentrators, and subsequently, a Cu-based nanostructured catalyst electrochemically converts CO? to ethylene C2H4. Carbon fiber sheet Gas-Diffusion Layer (GDL) was used as a platform to conduct the current and support the MOF and Cu catalyst for CO? capture and electrochemical reduction reaction, respectively. One side of the GDL was coated with Zinc-based MOF. The MOF layer served as a CO? concentrator and a screening stage, where it allows a higher percentage of CO? molecules to pass through the fiber to the other side. The other side of the GDL was coated with Cu?O particles to catalyze the electrochemical reduction reaction. The spray coating technique was used to spray coat MOF and Cu?O onto the carbon fiber. Binary gas feed N? 90%/CO? 10% at a relative humidity (RH%) of 10%, 30%, and 70% was used for the electrochemical reduction experiments in a flow-cell configuration. The results showed high C2H4 selectivity, conversion efficiency, and catalyst stability at RH 10% and 30%. Chapter 4 included the use of metal-organic frameworks (MOFs) and combining the desirable features of homogeneous and heterogeneous catalysts for boosting the activity of CO?RR. Zn-based MOFs involving two different azolate functional ligands, i.e., 1,2,4-triazolate (Calgary Framework-20, CALF20) and 2-methylimidazole (zeolitic imidazolate framework-8, ZIF-8), were investigated for CO?RR in an alkaline flow cell electrolyzer. In Chapter 5, we synthesized a composite of photoactive TiO?/MOF material for CO? capture and photoconversion. The TiO?/MOF composites were implemented in a photocatalytic reactor set-up to corroborate the CO? capture and photocatalytic conversion process. CO product was identified. The composite proved its ability to increase the CO yield up to 4.51 ?mol g-1h-1 with 70% CALF20 in the composite compared to 2.98 and 1.88 ?mol g-1h-1 for TiO? and CALF20 separately.

description: Data from the Lunar Exploration Neutron Detector (LEND) Collimated Sensors for Epithermal Neutrons (CSETN) are used in conjunction with a model based on results from the Lunar Prospector mission to quantify the extent of the background in the LEND CSETN. A simple likelihood analysis implies that at least 90% of the lunar component of the LEND CSETN flux results from high energy epithermal neutrons passing through the walls of the collimator. Thus, the effective full-width at half-maximum of the LEND CSETN is comparable with that of the omni-directional Lunar Prospector Neutron Spectrometer. The resulting map of high energy epithermal neutrons offers the opportunity to probe the hydrogen abundance at low latitudes, and provide constraints on the distribution of lunar water.

description: This project uses Critical Discourse Analysis to trace the ways in which neocolonial and Orientalist discourses shape the experiences of disabled and Mad Muslim women within and through disability and mental health care systems. Grounded in postcolonial thinking, this project uses Transnational Feminism, Critical Disability and Mad Studies, and Critical Race Theory to confront how racist, ableist, and sanist discourses construct and shape the experiences of disabled and Mad Muslim women within help and care contexts. I problematize key discourses and social processes that maintain imperial hegemony and essentialist constructs through the social cognition and ideologies of helping and caring professionals. I also illustrate how disabled and Mad Muslim women navigate colonial discourses of help and care, negotiate and reclaim their transnational identities, and engage in discursive resistance and antisubordination. I conclude by inviting social workers and other help and care professionals to consider their roles in maintaining power and control or in dislodging systems of oppression. I also offer some recommendations to help social work education, research, and practice better understand the realities of disabled and Mad Muslim women and be true to its commitment to social justice and transformation.

description: The synthesis of porous and robust metal-organic frameworks (MOFs) from dehydration of hydrogen bonded metal-organic frameworks (HMOFs) is reported. These HMOFs consist of [Cr(H2O)6]3+ clusters that hydrogen bond to phosphonate ligands which are converted into MOFs by heating. This dehydration causes displacement of the aquo ligands around the metal center with phosphonate groups. The strength of the Cr(III) – phosphonate coordination bonds results in highly stable MOFs, maintaining order and function after exposure to harsh conditions. Chapter 1 gives a broad overview of how porous materials are synthesized and discusses stability aspects of MOFs. Chapter 2 then introduces the methods employed for this thesis. The concept of converting an HMOF to MOF is introduced in Chapter 3, where a new HMOF, H-CALF-50 is heated and converted into the MOF, CALF-50 Results show that the MOF is crystalline and porous, with a BET surface area of 603 m2/g. The stability of the MOF is demonstrated as its surface area and PXRD pattern remain unchanged after refluxing in water for 3 weeks and soaking in concentrated acids for several days. Chapter 4 is an in-depth study of the dehydration mechanism. Another HMOF, H-CALF-45, is dehydrated by heating at various rates and by refluxing in various solvents. In doing this, a different MOF is synthesized depending on the different dehydration conditions used. Following this, Chapter 5 explores a dehydration method by soaking the HMOF, H-CrL3, in a solution of Cu(II) ions, generating bimetallic MOFs CrL3-Cu1, CrL3-Cu2, and CrL3-Cu-hy. Each of these MOFs have different Cu(II)/Cr(III) ratios which has direct impact on their gas sorption properties and stability. Altering the amount of Cu(II) or Cr(III) can tune the properties of the framework. Work in Chapter 6 applies the strategies developed from Chapter 5 to a Ni(II) based HMOF, H-NiL3. This HMOF consists of [Ni(H2O)6]2+ that hydrogen bonds to the phosphonate ligand, H8L3. Cr(III) ions are doped into H-NiL3 to afford H-NiL3-Cr, which appears to occur via an HMOF-to-HMOF conversion. This thesis concludes by discussing the applicability of the HMOFs as intermediates to synthesizing selective, porous, and ordered MOFs.

description: There exist two deformations of standard electrodynamics that describe Lorentz symmetry violation in the photon sector: CPT-odd Maxwell-Chern-Simons theory and CPT-even modified Maxwell theory. In this article, we focus on the parity-odd nonbirefringent sector of modified Maxwell theory. It is coupled to a standard Dirac theory of massive spin-1/2 fermions resulting in a modified quantum electrodynamics (QED). This theory is discussed with respect to properties such as microcausality and unitarity, where it turns out that these hold. Furthermore, a priori, the limit of the theory for vanishing Lorentz-violating parameters seems to be discontinuous. Since it is not clear, whether this is a gauge artifact, the cross section for a physical process - modified Compton scattering - is calculated numerically. Despite the numerical instabilities occurring for scattering of unpolarized electrons off polarized photons in the second physical polarization state, it is shown that for Lorentz-violating parameters much smaller than 1 the modified theory approaches standard QED, which is strengthened by analytical investigations. Hence, the theory proves to be consistent, at least with regard to the investigations performed. This leads to the interesting result of having a well-defined parity-odd extension of QED.

description: Type II topoisomerases (TOP2s) are essential enzymes that resolve topological challenges to assist in genome maintenance across all domains of life. Human topoisomerase II-beta (TOP2B) is one of two TOP2 isoforms in humans and other mammals that is required for organismal development and has important functions in processes like gene transcription and genome organization. Emerging evidence has linked TOP2B to the cellular response to DNA damage; TOP2B has been linked to the formation of DNA double-stranded DNA breaks (DSBs) and chromosome translocations. However, the links between TOP2B and DNA damage require further investigation and elucidation.This project describes work, primarily focusing on microscopy techniques, undertaken to better understand the role of TOP2B in the cellular response to DNA damage. The application of microscopy to studying TOP2B recruitment to and retention at sites of DNA damage required the development of an optimized image analysis protocol for live-cell images of laser microirradiation experiments. That optimized protocol was then applied to a series of laser microirradiation experiments investigating the properties of TOP2B recruitment to and retention at sites of DNA damage. Potential interactions of TOP2B with the DNA-dependent protein kinase catalytic subunit (DNA-PKcs) and poly (ADP)-ribose polymerase 1 (PARP1) were identified. It was also identified that a second TOP2 isoform, TOP2A, recruits to sites of DNA damage. Investigations were also made into whether the absence of TOP2B leads to an increase in the number of DSBs formed in response to ionizing radiation. Taken together, the results presented in this thesis provide a foundation for a new role of TOP2B in the cellular response to DNA damage.

description: A search is presented for production of a heavy up-type quark (t') together with its antiparticle, assuming subsequent decay to a W boson and a b quark, t't'bar -> W+b W-bbar. The search is based on 1.04 fb^-1 of proton-proton collisions at sqrt(s) = 7 TeV collected by the ATLAS detector at the CERN Large Hadron Collider. Data are analyzed in the lepton+jets final state, characterized by a high transverse momentum isolated electron or muon, high missing transverse momentum and at least three jets. No significant excess of events above the background expectation is observed. A 95% C.L. lower limit is set at m(t') > 404 GeV.

description: In this research, sulfolane removal from contaminated waters by aerobic biodegradation and adsorption were investigated. Sulfolane, an industrial solvent commonly used for sweetening of natural gas has recently emerged as a contaminant of concern because of its widespread use and detection in groundwaters around many gas processing sites. In this study, aerobic biodegradation of sulfolane by Pseudomonas sp. strain or Archaea strain and mixed bacterial cultures were studied. The investigation included a study on Pseudomonas sp. which had been acclimated to water contaminated with sulfolane. Parametric studies on the impact of co-contaminant, initial sulfolane concentration and soil content on biodegradation of sulfolane by acclimated Pseudomonas sp. were also conducted. The results showed that Pseudomonas sp. performed much better than Archaea in degrading sulfolane. Pseudomonas sp. and Archaea added to aquifer sediments containing indigenous microbes achieved higher sulfolane degradation. Acclimation of Pseudomonas sp. to sulfolane environment sufficiently mitigated the lag period before the onset of biodegradation process. Batch and fixed-bed adsorption experiments were conducted using activated carbon to remove sulfolane from aqueous media. Nine different commercially available activated carbons with different particle sizes and surface characteristics were obtained, and their effectiveness in removing sulfolane from water were evaluated. The impact of operational parameters such as pH, temperature, water quality and presence of co-contaminants on sulfolane adsorption was also investigated. In addition, pilot scale experiments were conducted to assess the applicability of activated carbon adsorption under field conditions. The results indicated that coconut shell based activated carbon has the highest sulfolane adsorption capacity. It was also noted that adsorption was significantly affected by the presence of co-contaminants. The pilot study indicated that activated carbon can be used to remove sulfolane from groundwater.

description: The top quark pair production and decay are considered in the framework of the smeared-mass unstable particles model. The results for total and differential cross sections in vicinity of $t\bar{t}$ threshold are in good agreement with the previous ones in the literature. The strategy of calculations of the higher order corrections in the framework of the model is discussed. Suggested approach significantly simplifies calculations compared to the standard perturbative one and can serve as a convenient tool for fast and precise preliminary analysis of processes involving intermediate time-like top quark exchanges in the near-threshold region.

description: We solve the open question of the existence of four-qubit entangled symmetric states with positive partial transpositions (PPT states). We reach this goal with two different approaches. First, we propose a half-analytical-half-numerical method that allows to construct multipartite PPT entangled symmetric states (PPTESS) from the qubit-qudit PPT entangled states. Second, we adapt the algorithm allowing to search for extremal elements in the convex set of bipartite PPT states [J. M. Leinaas, J. Myrheim, and E. Ovrum, Phys. Rev. A 76, 034304 (2007)] to the multipartite scenario. With its aid we search for extremal four-qubit PPTESS and show that generically they have ranks (5,7,8). Finally, we provide an exhaustive characterization of these states with respect to their separability properties.

description: High intensity interval training (HIIT) consists of a series of work intervals interspersed by recovery phases. This popular exercise paradigm has been hypothesized to mitigate metabolic by-product accumulation and to result in a disconnect between the work completed and the neuromuscular, perceptual, and cardiovascular responses to exercises performed in the severe domain. The HIIT characteristics such as the duration of work and recovery phases may modulate metabolic perturbations and influence psychophysiological responses determining exercise performance. One technique used in conjunction with HIIT is blood flow restriction (BFR). It is currently unknown how the durations of HIIT work and recovery phases, and the superimposition of BFR influence the integration of neuromuscular, perceptual, and cardiorespiratory responses determining exercise tolerance. Additionally, it is unknown how modulating HIIT work and recovery durations influences subsequent neuromuscular recovery kinetics. This thesis includes two studies. The objective of the first study was to compare the psychophysiological responses determining exercise tolerance during shorter HIIT, longer HIIT, and constant load (CL) protocols. The objective of the second study was to compare the integration of neuromuscular, perceptual, and cardiorespiratory indices of exercise tolerance during 1:1 min work-to-passive rest ratio HIIT with and without the application of BFR in males and females. The first investigation illustrated that shorter HIIT resulted in a greater task duration and reduced psychophysiological stress at a work-matched timepoint, while no differences were demonstrated at task failure. Additionally, this study demonstrated that after task failure, compared to the HIIT protocols, CL led to the most rapid recovery of neuromuscular fatigue. The second study illustrated that the application of BFR during HIIT rest intervals reduced exercise duration and exacerbated the rate of neuromuscular, perceptual, and cardiorespiratory responses in comparison to non-occluded HIIT. Additionally, BFR resulted in a greater rate of fatigability compared to control in females than males. Collectively, the findings demonstrate that longer HIIT work periods and the application of BFR reduce exercise capacity, which can be attributed to modulated psychophysiological alterations. Overall, these results have important implications to further our understanding of the physiological adaptations to HIIT and exercise prescription methods.

description: Artificial intelligence (AI) empowers machines to mimic the behaviors and thoughts of humans. With this technology now being used in all walks of life, it powers many real-world applications, ranging from language understanding to facial recognition. This thesis explores AI applications in two fields: high dynamic range (HDR) imaging and entrepreneurial prediction. In HDR imaging, multi-exposure fusion (MEF) is the easiest way to produce an HDR image without expensive professional cameras. Employing AI in MEF highly enhances the quality of generated HDR images compared to traditional hand-crafted methods. The neural networks (NNs) in these AI applications tend to be complex, with excessive parameters and heavy calculation costs. Hence, we propose a lightweight NN for MEF, consisting mainly of depthwise and pointwise convolution. Experimental results show that this proposed technique could generate HDR images in extremely exposed regions with sufficient details to be legible. Our model outperforms other state-of-the-art approaches in peak signal-to-noise ratio (PSNR) score by 0.9 to 8.7 while achieving 16.7 to 306.2 times parameter reduction. We also successfully develop our lightweight NN model on a Raspberry Pi and a field-programmable gate array (FPGA).In entrepreneurial prediction, this study focuses on female entrepreneurial success enhancement, which is rarely researched by scholars. We collect survey data from the “From Lab to Fulfillment” workshop focused on developing entrepreneurial skills amongst female academics. To augment the collected tabular dataset, we utilize the variational autoencoder (VAE) technique to generate artificial data. After training five machine learning algorithms on the combined dataset of the original and synthetic data, the result manifests that artificial data can improve the training performance of the models. This preliminary result also shows that the NN is the optimal predictive model with 70.3% precision, 74.7% recall, and 79.2% F1-score metric results. Based on this, we retrain the NN model and get a preliminary experimental result that Good Communicator is the most critical factor for female entrepreneurs’ success.
