Analysis of the effect of the fluid structure interface on elastic wave velocity in cornea like structures by OCE and FEM

Air pulse optical coherence elastography (OCE) is a promising technique for quantifying biomechanical properties of the cornea. This technique typically involves imaging and analysis of the propagation of the air pulse induced elastic waves to reconstruct corneal biomechanical properties using an analytical model. However, the effect of the fluid structure interface (FSI) at the corneal posterior surface on the elastic wave velocity is not accounted for in many models. In this study, we examined the effect of the FSI with OCE experiments on contact lenses with and without fluid in the posterior gap. Finite element models (FEM) also with and without the FSI, were constructed to simulate the elastic wave propagation based on the OCE measurements. The FEM and OCE results were in good agreement demonstrating the feasibility of the method. To further investigate the effect of the FSI, OCE experiments and subsequent FEM simulations were conducted on in situ rabbit corneas before and after rose bengal/green light corneal collagen cross linking (RGX) Both the OCE experiments and the FE simulations demonstrated that the FSI significantly reduced the group velocity of the elastic wave, and thus, should be considered when determining corneal biomechanical properties from an appropriate mechanical model. By matching the FEM calculated velocity to the OCE measured velocity, the corneal elasticity was quantified. The Young's modulus of the rabbit cornea before RGX was E??65??10 kPa at a controlled intraocular pressure (IOP) of 15 mmHg. After RGX, the Young's modulus increased to E??102??7 kPa at the same IOP.
Two cases of lung metastasis originating from acquired cystic kidney disease associated carcinoma

Case 1 involved a 70 year old man on hemodialysis for chronic nephritis for 19 years, who had undergone left nephrectomy for acquired cystic kidney disease (ACKD) associated renal cell carcinoma (RCC) (pT2aN0M0; stage II) 5 years earlier. An abnormal pulmonary nodule was detected on follow up chest computed tomography (CT) We performed wedge resection of the right lower lobe, and diagnosed metastatic lung tumor originating from ACKDassociated RCC histopathologically. Case 2 involved a 52 year old man on hemodialysis for diabetic nephropathy for 14 years, who had undergone bilateral nephrectomy for ACKD associated RCC (pT2aN0M0; stage II) 1 year earlier. An abnormal pulmonary nodule was detected on follow up CT. We performed wedge resection of the right lower lobe, and diagnosed metastatic lung tumor originating from ACKD associated RCC histopathologically. Although the prognosis of ACKD associated RCC is favorable and lung metastasis is rare, annual systemic screening appears important for good prognosis.
Accelerating poverty reduction in Mozambique challenges and opportunities

Over the past two decades Mozambique enjoyed robust and accelerating economic growth, yet strong economic progress only translated into modest poverty reduction. Not only poverty fell at slower pace than expected but the gains in income and consumption growth are unevenly distributed across the country and across groups of people. Some parts of the country especially the center and the north account for a disproportionate share of the poor. Overall, urban provinces tend to have lower poverty rates than rural provinces, particularly those in the central and northern parts of the country. Three factors contribute to the low equity outcomes in Mozambique: (i) unequal access to economic opportunities across regions and income groups; (ii) low productivity and market based growth in agriculture; and (iii) high vulnerability to weather shocks. Growth could have had a much larger impact on poverty reduction in Mozambique if its effects had not been offset by the observed increase in inequality. Accelerating poverty reduction requires addressing structural factors that undermine the inclusiveness of growth. The returns to growth have to be distributed more widely to invest in the most isolated parts of the country in for these regions to be able to seize the economic opportunities brought about by economic expansion and close the gap with the rest of the country. There is a need to deepen the investments in the human, physical and institutional capital of the country. Finally, given the high exposure of Mozambique to natural disasters, it is necessary to strengthen formal and informal risk management systems to avoid that the living standards of the population are highly influenced by major shocks out of their control.
Annona muricata: A comprehensive review on its traditional medicinal uses, phytochemicals, pharmacological activities, mechanisms of action and toxicity

Annona muricata L.  Annonaceae) is a tropical plant species known for its edible fruit which has some medicinal merits, but also some toxicological effects. This review focuses on the phytochemicals contents, bioactivity, biological actions and toxicological aspects of extracts and isolated compounds, as well as medicinal uses of A. muricata, with the objective of stimulating further studies on extracts and fruit pulp used for human consumption. Traditional medicinal uses of A. muricata have been identified in tropical regions to treat diverse ailments such as fever, pain, respiratory and skin illness, internal and external parasites, bacterial infections, hypertension, inflammation, diabetes and cancer. More than 200 chemical compounds have been identified and isolated from this plant; the most important being alkaloids, phenols and acetogenins. Using in vitro studies, extracts and phytochemicals of A. muricata have been characterized as an antimicrobial, anti inflammatory, anti protozoan, antioxidant, insecticide, larvicide, and cytotoxic to tumor cells. In vivo studies of the crude extracts and isolated compounds of A. muricata were shown to possess anxiolytic, anti stress, anti inflammatory, contraceptive, anti tumoral, antiulceric, wound healing, hepato protective, anti icteric and hypoglycemic activities. In addition, clinical studies support the hypoglycemic activity of the ethanolic extracts of A. muricata leaves. Mechanisms of action of some pharmacological activities have been elucidated, such as cytotoxic, antioxidant, antimicrobial, antinociception and hypotensive activities. However, some phytochemical compounds isolated from A. muricata have shown a neurotoxic effect in vitro and in vivo, and therefore, these crude extracts and isolated compounds need to be further investigated to define the magnitude of the effects, optimal dosage, mechanisms of action, long term safety, and potential side effects. Additionally, clinical studies are necessary to support the therapeutic potential of this plant.
Impact of Government Spending on Small and Medium Scale Businesses in Nigeria

This paper examines the impact of public expenditure on the output and productivity of small and medium scale enterprises in Nigeria using annual time series data for the period of 1970 2015. The experiment was conducted using the specifications of the law as outlined in the public expenditure literature. Including others methods and models, first, we check for the time series properties of the valuables used by applying the ADF, PP and the KPSS test statistics, also, the Johansen's co integration test procedure as well as the autoregressive distributed lag (ARDL) bounds testing approach were employed. Result of the study revealed that: Generally, all the variables were found to be stationary at their first differences, except government expenditure which was stationary at level. The result also shows a long run unidirectional causality from SMEs output and productivity to public expenditure. However, in other instances, there was bidirectional causality between SMEs output and productivity and public expenditure. Indeed, it was found that while causality runs from SMEs output and productivity to public expenditure in the long run, short run changes in SMEs output and productivity was cause by changes in public expenditure. The conclusion from these results is that while there is a strong support for Wagner's postulation of a long run tendency for public expenditure to grow relative to national income in Nigeria over the period 1970 2015, public expenditure still remains a veritable short term instrument that can be used to spur economic growth and development in Nigeria.
Utilizing a Simulation within an Online School Technology Leadership Course.

Online courses and programs have grown to become and continue to be a popular option for students. As part of an online Master's of Education in Instructional Technology program, students must complete a school technology leadership course. Leadership decision making, policy making, and how to have innovations take hold in a school settings are important things to learn about, but are even more important concepts for students to be able to practice. This case study details the reasoning behind, utilization of, adjustments to, and results from bringing a simulation into the program's online school technology leadership course. Results show that students found the simulation to provide a mostly authentic experience and grew to understand that they should view the simulation as a system, but some students were averse to risk taking and were not always able to adjust to details within the simulation that challenged their existing schema regarding technology leadership and how innovations are diffused within a school setting.
Scaling Up Youth Led Social Justice Efforts through an Online School Based Social Network.
Venue: American journal of community psychology

The exploration of social networking sites (SNS) in promoting social change efforts offers great potential within the field of community psychology. Online communities on SNS provide opportunities for bridging across groups, thus fostering the exchange of novel ideas and practices. Currently, there have only been limited efforts to examine SNS within the context of youth led efforts. To explore the potential of SNS to facilitate the diffusion of social justice efforts between distinct youth groups, we linked three school based youth led participatory action research projects involving 54 high school students through a SNS. This study offers an innovative methodological approach and framework, utilizing social network analysis and strategic sampling of key student informants to investigate what individual behaviors and online network features predict student adoption of social change efforts. Findings highlight prospective facilitators and barriers to diffusion processes within a youth led online network, as well as key constructs that may inform future research. We conclude by providing suggestions for scholars and practitioners interested in examining how SNS can be used to enhance the diffusion of social justice strategies, youth led engagement efforts, and large scale civic organizing.
Pilot test of StandUp, an online school based bullying prevention program

Bullying is a significant public health problem for students in schools. Prevention programs have addressed targets with some success; however, meta analyses find small effects among older youths. A pilot study was conducted with high school students to evaluate the potential efficacy of StandUp, a three session online program that delivers assessments and individualized guidance matched to bullying experiences and stage of readiness for using healthy relationship skills. Of the 113 students participating in the study, 88 completed all three intervention sessions. Use of healthy relationship skills increased significantly from session 1 to session 3. In addition, compared with session 1, participants at session 3 had reduced odds of perpetrating and experiencing emotional and physical bullying, and of passively standing by as others were bullied; odds ratios ranged from.29 to.63, with most bullying outcomes approaching or reaching statistical significance. StandUp is a bullying prevention program for adolescents that showed encouraging changes in behavior from first to third session in a small sample of high school students. Because it is easy to use, guarantees fidelity of administration, and does not require extensive staff time, StandUp may be a useful addition to the array of school based programs to address bullying.
The Private and Public Correlation Cost of Three Random Variables With Collaboration
Venue: IEEE Transactions on Information Theory

In this paper, we consider the problem of generating arbitrary three party correlations from a combination of public and secret correlations. Two parties called Alice and Bob share perfectly correlated bits that are secret from a collaborating third party, Charlie. At the same time, all three parties have access to a separate source of correlated bits, and their goal is to convert these two resources into multiple copies of some given tripartite distribution P(XYZ) We obtain a single letter characterization of the tradeoff between public and private bits that are needed to achieve this task. The rate of private bits is shown to generalize Wyner's classic notion of common information held between a pair of random variables. The problem we consider can be contrasted fruitfully with the task of secrecy formation, in which P(XYZ) is generated using public communication and local randomness but with Charlie functioning as an adversary instead of a collaborator. We describe in detail the differences between the collaborative and adversarial scenarios.
Noncovalent Immobilization of a Molecular Iron Based Electrocatalyst on Carbon Electrodes for Selective, Efficient CO2 to CO Conversion in Water.
Venue: Journal of the American Chemical Society

Catalysis of fuel producing reactions can be transferred from homogeneous solution to surface via attachment of the molecular catalyst. A pyrene appended iron triphenyl porphyrin bearing six pendant OH groups on the phenyl rings in all ortho and ortho' positions was immobilized on carbon nanotubes via noncovalent interactions and further deposited on glassy carbon. X ray photoelectron spectroscopy and electrochemistry confirm catalyst immobilization. Using the carbon material, highly selective and rapid catalysis of the reduction of CO2 into CO occurs in water (pH 7.3) with 480 mV overpotential. Catalysis could be sustained for hours without loss of activity and selectivity, and high turnover number was obtained.

Improving supply chain information sharing using Design for Six Sigma

Accurate and reliable information is needed to support decision making processes. Due to the large number of participants typically involved in supply chain operations, organizations often find thatitis difficult to effectively share information within a supply chain; hence, this research examined ways to improve information sharing within supply chain operations for one marine transportation services organization. An action research, case study approach used the Design for Six Sigma (DFSS) methodology to design an information technology solution that effectively communicates information between the layers within the supply chain regarding the movement of materials via inland tank barges. The comparative analysis of verification and baseline measurements conducted suggests this project was successful because the new process fulfilled the needs of the work environment for which it was designed. For the organization that participated in this research, the successful adoption of the new approach for information sharing improved communication and decision making within their supply chain. Este trabajo se fundamenta en la necesidad de contar con informacion precisa y fiable en los procesos de toma de decisiones.

Meta Path Based Top K Similarity Join In Heterogeneous Information Networks

Heterogeneous information networks (HINs) has received growing attention in a newly emerging network model. Clustering, classification and similarity search are the data mining tasks explored in HINs. Similarity join operation is required for many problems which is attracting attention from various applications on network data which includes friend recommendation, link prediction and online advertising. Similarity join is studied in homogeneous network but not studied in heterogeneous networks. The heterogeneity of the HINs are ignored completely by the previous research on similarity join which takes different semantic meanings. A Meta Path based Similarity join (MPS join) method to return the top k similar pairs of objects based on the user specified join path in a HIN is proposed and to prune expensive similarity computation by using BPLSH (Bucket Pruning based Locality Sensitive Hashing) indexing. When compared to the existing Link based Similarity join (LS join) method, this MPSjoin method derives various similarity semantics. The experimental results on real data sets shows the efficiency and effectiveness of the proposed approach.
Platinum single atom and cluster catalysis of the hydrogen evolution reaction
Venue: Nature communications

Platinum based catalysts have been considered the most effective electrocatalysts for the hydrogen evolution reaction in water splitting. However, platinum utilization in these electrocatalysts is extremely low, as the active sites are only located on the surface of the catalyst particles. Downsizing catalyst nanoparticles to single atoms is highly desirable to maximize their efficiency by utilizing nearly all platinum atoms. Here we report on a practical synthesis method to produce isolated single platinum atoms and clusters using the atomic layer deposition technique. The single platinum atom catalysts are investigated for the hydrogen evolution reaction, where they exhibit significantly enhanced catalytic activity (up to 37 times) and high stability in comparison with the state of the art commercial platinum/carbon catalysts. The X ray absorption fine structure and density functional theory analyses indicate that the partially unoccupied density of states of the platinum atoms' 5d orbitals on the nitrogen doped graphene are responsible for the excellent performance.
