Sustainable Cities and Communities from Malaysian Local Authorities Perspectives

Perspectives of Malaysian local authorities on the development of sustainable cities and communities (SCC) are examined in this study, with a focus on the effects of cost-benefit analysis (CBA), private finance initiatives, and risk management. Additionally, the challenges faced by local authorities in developing SCC are presented. A qualitative method was used, involving face-to-face interviews with local authorities. Content analysis was conducted, and the results show that CBA, private finance initiatives, and risk management have a significant impact on the development of SCC. The primary challenge in implementing SCC is the limited funding available to support their implementation. This study sheds light on the importance of considering CBA, private finance initiatives, and risk management in developing SCC from the perspective of Malaysian local authorities. The findings also highlight the need for more funding and resources to support SCC implementation in Malaysia.
Critical Points Of An Autoencoder Can Provably Recover Sparsely Used Overcomplete Dictionaries

In Dictionary Learning one is trying to recover incoherent matrices A∗ ∈ Rn×h (typically overcomplete and whose columns are assumed to be normalized) and sparse vectors x∗ ∈ R with a small support of size h for some 0 < p < 1 while being given access to observations y ∈ R where y = A∗x∗. In this work we undertake a rigorous analysis of the possibility that dictionary learning could be performed by gradient descent on Autoencoders, which are R → R neural network with a single ReLU activation layer of size h. Towards the above objective we propose a new autoencoder loss function which modifies the squared loss error term and also adds new regularization terms. We create a proxy for the expected gradient of this loss function which we motivate with high probability arguments, under natural distributional assumptions on the sparse code x∗. Under the same distributional assumptions on x∗, we show that, in the limit of large enough sparse code dimension, any zero point of our proxy for the expected gradient of the loss function within a certain radius of A∗ corresponds to dictionaries whose action on the sparse vectors is indistinguishable from that of A∗. We also report simulations on synthetic data in support of our theory. ∗Equal Contribution †rangamani.akshay@jhu.edu ‡amukhe14@jhu.edu aarora8@jhu.edu ¶tganapathi@salesforce.com ‖basu.amitabh@jhu.edu ∗∗spchin@cs.bu. edu ††trac@jhu.edu 1 ar X iv :1 70 8. 03 73 5v 1 [ cs .

Comparison of Economic Geography Contents in Turkey and Turkmenistan Geography Curriculum: Grades 10th, 11th and 12th

Education curricula are programs that include topics for students’ academic achievement and individual development. Geography curricula cover many subjects such as physical, human, economic and environmental issues. In this study, the economic geography contents of Turkey and Turkmenistan high school geography curricula were compared in the study. Firstly, the content of 10th, 11th and 12th grades in the geography programs of both countries was investigated and evaluated. The study is qualitative in nature as it is mainly based on document analysis. Economic geography topics in geography programs according to grade levels were examined and the similarities and differences between the economic geography subjects in the geography programs of both countries were determined. In both countries, economic geography subjects are included in the 12-year compulsory education, especially after the 10th grade. Moreover, both programsinclude economic geography topics from a local to global scale.
Inequality, Social Mobility and Redistributive Preferences

Previous studies on preferences for redistribution have shown that even though information on inequality changes concerns about inequality, it barely changes redistributive preferences. In an online experiment, we challenge previous results by showing US citizens a short video with facts on both inequality and social mobility and test the impact on different redistributive policies. Information on inequality of outcomes increases consensus on a more progressive tax system, whereas information on lack of equal opportunities increases participants’ preferences for redistribution via fiscal spending. Both informational treatments have a stronger impact when participants also learn that higher inequality is not a necessary part of economic development. All informational treatments have a stronger impact for citizens, who underestimate the current level of inequality and trust the government. JEL Classification: D31, D63, D90, H20, H40)
Characteristics, surgical outcomes, and influential factors of epilepsy in Sturge-Weber syndrome.

Few studies have reported the clinical presentation, surgical treatment, outcomes, and influential factors for patients with epilepsy and Sturge-Weber syndrome. This large-scale retrospective study continuously enrolled 132 patients with Sturge-Weber syndrome and epilepsy from January 2008 to December 2018 at our hospital to analyze their characteristics. Among these patients, 90 underwent epilepsy surgery, and their postoperative 2-year follow-up seizure, cognitive, and motor functional outcomes were assessed and analyzed. Univariable and multivariable logistic analyses were conducted to explore the influential factors. Among the Sturge-Weber syndrome patients for whom characteristics were analyzed (n = 132), 76.52% of patients had their first epileptic seizures within their first year of life. The risk factors for cognitive decline were seizure history≥2 years (adjusted odds ratio [aOR] = 3.829, 95% confidence interval [CI]: 1.810-9.021, p = 0.008), bilateral leptomeningeal angiomas (aOR = 3.173, 95% CI: 1.970-48.194, p = 0.013), age at onset < 1 year (aOR = 2.903, 95% CI: 1.230-6.514, p = 0.013), brain calcification (aOR = 2.375, 95% CI: 1.396-5.201, p = 0.021) and left leptomeningeal angiomas (aOR = 2.228, 95% CI: 1.351-32.571, p = 0.030). Of the patients who underwent epilepsy surgery (n = 90), 44 were subject to focal resection, and 46 underwent hemisphere surgery (19 anatomical hemispherectomies and 27 modified hemispherotomies). A postoperative seizure-free status, favorable cognitive outcomes, and favorable motor outcomes were achieved in 83.33%, 44.44%, and 43.33% of surgical patients, respectively. The modified hemispherotomy group had similar surgical outcomes, less intraoperative blood loss and shorter postoperative hospital stays than the anatomical hemispherectomy group. Regarding seizure outcomes, full resection (aOR = 11.115, 95% CI: 1.260-98.067, p = 0.020) and age at surgery < 2 years (aOR = 6.040, 95% CI: 1.444-73.367, p = 0.031) were positive influential factors for focal resection. Age at surgery < 2 years (aOR = 15.053, 95% CI: 1.050-215.899, p = 0.036) and infrequent seizures (aOR = 8.426, 95% CI: 1.086-87.442, p = 0.042; monthly vs. weekly) were positive influential factors for hemisphere surgery. In conclusion, epilepsy surgery resulted in a good postoperative seizure-free rate and favorable cognitive and motor functional outcomes and showed acceptable safety for patients with epilepsy and Sturge-Weber syndrome. Modified hemispherotomy is a less invasive and safer type of hemisphere surgery than traditional anatomic hemispherectomy with similar surgical outcomes. Early surgery may be helpful to achieve better seizure outcomes and cognitive protection, while the risk of surgery for young children should also be considered.
Limits of the Bogus Pipeline Condition: An Examination of Null Findings in an Experimental Study

This study examined the impact of three experimental conditions on antisemitism, right-wing authoritarianism (RWA), religious fundamentalism, and social desirability. Participants (N = 102) were university students (74.5% women; 49% non-Hispanic White/European American). Participants were randomly assigned to experimental conditions (i.e., control, bogus pipeline, altered bogus pipeline) and completed measures of demographics, social desirability, antisemitism, RWA, and religious fundamentalism. Analyses were conducted to examine differences in study variables across experimental groups. Results revealed significant differences in social desirability across bogus pipeline and altered bogus pipeline conditions, with social desirability being significantly lower in the bogus pipeline condition. Results were nonsignificant for antisemitism, RWA, and religious fundamentalism. Findings highlight potential limits in the efficacy of the bogus pipeline condition.
Demographic Characteristics and Business Performance: Evidence in Women Entrepreneurs

The existence of women entrepreneurs in the industrial world today deserves to be maintained and improved. There are several beneﬁts of women becoming entrepreneurs, namely creating jobs, encouraging economic growth and increasing social welfare. The existence of women entrepreneurs will continue to be maintained if women entrepreneurs are able to achieve good business performance. One of the factors that inﬂuence the business performance of women entrepreneurs is demographic characteristics. The purpose of this study was to analyze the effect of demographic characteristics consisting of age, business age, income and education level on the business performance of women entrepreneurs. The focus of this research is women entrepreneurs in West Sumatra. Data were collected using a questionnaire. This research uses multiple linear regression analysis technique. The results showed that age, business age and education level had a signiﬁcant positive effect on the business performance of women entrepreneurs. Based on the results of the study, it can be concluded that business performance is formed from the process and time and also matures the age and level of education of the women entrepreneurs.
Reduced Tetracycline Resistance When RpoS is Over-Produced Through Heat Shock in Escherichia coli

The stationary phase sigma factor, RpoS, present in Escherichia coli is responsible for the phenomenon known as cross-protection where the cell acquires secondary resistance to a stress factor once exposed to an unrelated primary stress. Previous studies have shown contradictory observations based on the effects of RpoS overproduction where one study observed a positive outcome and another study observed an inhibitory outcome. Our study tested the possibility that low levels of RpoS contributed to positive cellular protection and higher levels contributed to inhibition of cell protection. RpoS was overexpressed in both a wild type strain, BW28357, and Δ rpoS , BW28465, E. coli strain though heat shock at 45 °C for various lengths of time. Minimum inhibitory concentration (MIC) assays with tetracycline were performed in order to determine conferred levels of protection. RpoS was then isolated and quantified using Western blot. Western blot results revealed an increase in RpoS concentration with prolonged heat shock. Western blot analysis coupled with MIC results revealed that protection against tetracycline was diminished as RpoS expression was upregulated beyond a certain level. The gram-negative enteric bacterium, Escherichia coli , is
EpCAM expression negatively regulates E-cadherin function in colorectal carcinomas

Background This study aimed to characterise epithelial cell adhesion molecule (EpCAM) expression patterns in colorectal carcinomas (CRC) from Nigerian patients, its association with E-cadherin and tumour characteristics, to forecast patient selection for anti-EpCAM therapy among whom no data existed previously. Methods Tissue microarray blocks of formalin-fixed and paraffin-embedded CRC tissues, with their non-cancer margins of resection, were sectioned and stained with EpCAM and E-cadherin primary antibodies. Scoring for antibody staining was done semiquantitatively by combining staining proportion and intensity. The outcome was correlated with patient age, gender and tumour histological parameters with p ≤ 0.05 regarded as statistically significant. Results Sixty-three carcinoma tissues had staining status for the two markers and were included in this study. Of these, 36 (57.1%) showed positive EpCAM expression (immunoscore ≥3) out of which 83% (30/36 positive cases) were overexpressed (combined immunoscore ≥4) while 12 (19%) tissues were positive for E-cadherin. Non-tumour margins of resection tissues showed less EpCAM positivity in 24% (6/25) of histospots. The difference in staining between tumour and non-tumour margin tissues with EpCAM was significant (p < 0.001). Also, EpCAM overexpression was significantly associated with reduced E-cadherin (p < 0.035) expression in tumour cells. Tumour extent within the gut wall was equal (50% each) for early and late pT stages among EpCAM overexpressing tumours but two-thirds (8/12) of cases expressing E-cadherin had later pT stage paradoxically, while distant metastasis was negligible among tumours bearing both markers. Also, tumours overexpressing EpCAM had significant association with tumour-associated lymphocytes (p < 0.02 each). Conclusion CRC in this study preferentially overexpress EpCAM over E-cadherin whose strong cell-cell contact inhibitory role is weakened even when expressed, resulting in further local tumour spread. This, and the observed immune response, supports targeted therapy among eligible patients.

BIOLOŠKO AKTIVNI METABOLITI EKSTREMOFILNIH GLIVNIH VRST IZ RODU Wallemia: IZOLACIJA, STRUKTURA IN BIOLOŠKA AKTIVNOST

Rod Wallemia obsega tri vrste, Wallemia sebi, Wallemia ichthyophaga in Wallemia muriae. W. sebi je kserotolerofilna, ubikvitarna, z živili povezana mikotoksigena gliva, ki je bila do leta 2005 tudi edina znana vrsta omenjenega rodu. V dostopni literaturi je le skopo opisana bioloska aktivnost mikotoksinov, ki jih omenjena vrsta producira zatorej smo v doktorski nalogi podrobneje raziskali ucinek izoliranih glivnih metabolitov iz vrst Wallemia na rdece krvne celice, kaksno afiniteto izkazujejo do umetnih lipidnih veziklov ter tudi identificirali njihovo kemijsko strukturo. Ekstrakti, pridobljeni iz glivne biomase W. sebi s pomocjo kloroforma, superkriticnega CO2 in etanola, so izkazovali mocno hemoliticno aktivnost, ki je bila pri nižji vodni aktivnosti v rastnem gojiscu glive vecinoma izrazitejsa. V testu liticnosti eritrocitov se je izkazalo, da je hemoliza odvisna od koncentracije etanolnega ekstrakta ter je mocnejsa v primeru bolj fluidnih membran. Analiza etanolnega ekstrakta in ekstrakta pridobljenega s superkriticnim CO2, opravljena s plinsko kromatografijo z masno spektrometricnim detektorjem je pokazala prisotnost mesanice sterolov in nenasicenih mascobnih kislin. Slednje smo potrdili kot povzrociteljice hemolize v bioloskem testu. Liticna aktivnost W. sebi kaže na potencialno vlogo izoliranih metabolitov pri tvorbi lezij ob subkutanih infekcijah, pri pljucih poljedelcev ter po zaužitju kontaminiranih živil, z glivo W. sebi. V doktorski nalogi se prvic omenja tudi produkcija hemoliticno aktivnih metabolitov s strani drugih dveh vrst iz rodu Wallemia.
Sag-Free Initialization for Strand-Based Hybrid Hair Simulation

Lagrangian/Eulerian hybrid strand-based hair simulation techniques have quickly become a popular approach in VFX and real-time graphics applications. With Lagrangian hair dynamics, the inter-hair contacts are resolved in the Eulerian grid using the continuum method, i.e., the MPM scheme with the granular Drucker-Prager rheology, to avoid expensive collision detection and handling. This fuzzy collision handling makes the authoring process significantly easier. However, although current hair grooming tools provide a wide range of strand-based modeling tools for this simulation approach, the crucial sag-free initialization functionality remains often ignored. Thus, when the simulation starts, gravity would cause any artistic hairstyle to sag and deform into unintended and undesirable shapes. This paper proposes a novel four-stage sag-free initialization framework to solve stable quasistatic configurations for hybrid strand-based hair dynamic systems. These four stages are split into two global-local pairs. The first one ensures static equilibrium at every Eulerian grid node with additional inequality constraints to prevent stress from exiting the yielding surface. We then derive several associated closed-form solutions in the local stage to compute segment rest lengths, orientations, and particle deformation gradients in parallel. The second global-local step solves along each hair strand to ensure all the bend and twist constraints produce zero net torque on every hair segment, followed by a local step to adjust the rest Darboux vectors to a unit quaternion. We also introduce an essential modification for the Darboux vector to eliminate the ambiguity of the Cosserat rod rest pose in both initialization and simulation. We evaluate our method on a wide range of hairstyles, and our approach can only take a few seconds to minutes to get the rest quasistatic configurations for hundreds of hair strands. Our results show that our method successfully prevents sagging and has minimal impact on the hair motion during simulation.
Simulating cavitation over different scales and regimes

Cavitation is investigated over a range of scales and regimes for various flow configurations. At the bubble scale level, a volume-of-fluid (VOF) based incompressible flow solver is developed, and three canonical bubble collapse problems are simulated for validation. The results obtained from the VOF model show good agreement with past experiments and numerical simulations. The ability to study and track multiple bubbles is also incorporated in the context of the VOF model via a Lagrangian tagging algorithm. For cavitation inception, we study a shear layer at Re τ = 1500. Joint–PDFs of the flow invariants are obtained along the shear layer and the cores of the elongated vortices are found to be the regions most likely to experience inception. These regions have a rotation rate 4 × stronger than the stretching rate. Lastly, a fully compressible multi–scale method accounting for both the sheet cavities and the micro-bubbles is developed and validated. This model is applied to a case where both the unresolved and resolved bubble coexist and the findings are discussed.
Transcatheter Mitral Valve Replacement: Structural and Hemodynamic Analysis

Transcatheter mitral valve replacement (TMVR) is being developed to become a substitute therapy for surgery in prohibitive or high surgical risk patients to treat severe mitral regurgitation. A limited number of TMVR systems are under clinical evaluation. However, transcatheter mitral valve (TMV) long-term durability and hemodynamic performance is not known. TMV durability and hemodynamics must match with that of surgical bioprostheses for potential commercialization of TMVR. Experimental and computational approaches were used to find the leaflets’ three-dimensional anisotropic mechanical properties in a transcatheter Edwards SAPIEN 3 valve and a surgical Carpentier-Edwards PERIMOUNT Magna mitral valve and finite element (FE) simulations were conducted to obtain the stress distribution on both valves. Moreover, to visualize the flow field within the left heart, steady-state computational fluid dynamics (CFD) simulations were run. The FE simulations demonstrated that in a cardiac cycle, at peak systole, the highest stress value in the two bioprostheses was 4.75 and 16 MPa for the surgical and transcatheter heart valve, respectively. After studying the leaflet stress distributions and flow field, long-term durability may potentially be different between the two models. The results of CFD simulations could potentially show that TMVs with supraannular positioning have a higher risk of leaflet thrombosis as opposed to the intra-annular position.
