Neuron Depot: keeping your colleagues in sync by combining modern cloud storage services, the local file system, and simple web applications
Neuroscience today deals with a "data deluge" derived from the availability of high-throughput sensors of brain structure and brain activity, and increased computational resources for detailed simulations with complex output. We report here (1) a novel approach to data sharing between collaborating scientists that brings together file system tools and cloud technologies, (2) a service implementing this approach, called NeuronDepot, and (3) an example application of the service to a complex use case in the neurosciences. The main drivers for our approach are to facilitate collaborations with a transparent, automated data flow that shields scientists from having to learn new tools or data structuring paradigms. Using NeuronDepot is simple: one-time data assignment from the originator and cloud based syncing thus making experimental and modeling data available across the collaboration with minimum overhead. Since data sharing is cloud based, our approach opens up the possibility of using new software developments and hardware scalabitliy which are associated with elastic cloud computing. We provide an implementation that relies on existing synchronization services and is usable from all devices via a reactive web interface. We are motivating our solution by solving the practical problems of the GinJang project, a collaboration of three universities across eight time zones with a complex workflow encompassing data from electrophysiological recordings, imaging, morphological reconstructions, and simulations
Familial Mediterranean fever, Inflammation and Nephrotic Syndrome: Fibrillary Glomerulopathy and the M680I Missense Mutation
BACKGROUND: Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by inflammatory serositis (fever, peritonitis, synovitis and pleuritis). The gene locus responsible for FMF was identified in 1992 and localized to the short arm of chromosome 16. In 1997, a specific FMF gene locus, MEFV, was discovered to encode for a protein, pyrin that mediates inflammation. To date, more than forty missense mutations are known to exist. The diversity of mutations identified has provided insight into the variability of clinical presentation and disease progression. CASE REPORT: We report an individual heterozygous for the M680I gene mutation with a clinical diagnosis of FMF using the Tel-Hashomer criteria. Subsequently, the patient developed nephrotic syndrome with biopsy-confirmed fibrillary glomerulonephritis (FGN). Further diagnostic studies were unremarkable with clinical workup negative for amyloidosis or other secondary causes of nephrotic syndrome. DISCUSSION: Individuals with FMF are at greater risk for developing nephrotic syndrome. The most serious etiology is amyloidosis (AA variant) with renal involvement, ultimately progressing to end-stage renal disease. Other known renal diseases in the FMF population include IgA nephropathy, IgM nephropathy, Henoch-Schönlein purpura as well as polyarteritis nodosa. CONCLUSION: To our knowledge, this is the first association between FMF and the M680I mutation later complicated by nephrotic syndrome and fibrillary glomerulonephritis
Energy recovery from waste in India:an evidence-based analysis
The uptake of Waste-to-Energy (WtE) in India has not been successful and the majority of plants have failed to sustain operations. There is a lack of detailed on-the-ground research examining the causes of plant failures and the issues regarding the WtE supply chain. Thus, this study set out to identify how WtE practices in India can be improved by gathering and evaluating empirical evidence. Local government officers, industry practitioners and academics involved in waste management in India were consulted. Quantitative data were collected on three case study plants: an incinerator, a gasification plant and a plant co-firing waste with coal. The gathered information was evaluated by making a comparison with two European waste incinerators. The major problem with WtE in India has typically been perceived to be poor source segregation; however, the case study plants highlight that severe contamination has been occurring during transport and storage. In comparison to the European incinerators, the WtE plants in India had a low capital cost (around 1–2 million €/MW), but total particulate matter emissions were a hundred times higher, ranging from 65 to 75 mg/Nm3. We conclude with recommendations for delivery contracts, financial incentives and regulations on dumpsites, ash disposal and stack emission measurements
Latent variables and route choice behavior
In the last decade, a broad array of disciplines has shown a general interest in enhancing discrete choice models by considering the incorporation of psychological factors affecting decision making. This paper provides insight into the comprehension of the determinants of route choice behavior by proposing and estimating a hybrid model that integrates latent variable and route choice models. Data contain information about latent variable indicators and chosen routes of travelers driving regularly from home to work in an urban network. Choice sets include alternative routes generated with a branch and bound algorithm. A hybrid model consists of measurement equations, which relate latent variables to measurement indicators and utilities to choice indicators, and structural equations, which link travelers' observable characteristics to latent variables and explanatory variables to utilities. Estimation results illustrate that considering latent variables (i.e., memory, habit, familiarity, spatial ability, time saving skills) alongside traditional variables (e.g., travel time, distance, congestion level) enriches the comprehension of route choice behavior
Bioavailability of Iron, Zinc, Phytate and Phytase Activity during Soaking and Germination of White Sorghum Varieties
The changes in phytate, phytase activity and in vitro bioavailability of iron and zinc during soaking and germination of three white sorghum varieties (Sorghum bicolor L. Moench), named Dorado, Shandweel-6, and Giza-15 were investigated. Sorghum varieties were soaked for 20 h and germinated for 72 h after soaking for 20 h to reduce phytate content and increase iron and zinc in vitro bioavailability. The results revealed that iron and zinc content was significantly reduced from 28.16 to 32.16% and 13.78 to 26.69% for soaking treatment and 38.43 to 39.18% and 21.80 to 31.27% for germination treatments, respectively. Phytate content was significantly reduced from 23.59 to 32.40% for soaking treatment and 24.92 to 35.27% for germination treatments, respectively. Phytase enzymes will be activated during drying in equal form in all varieties. The results proved that the main distinct point is the change of phytase activity as well as specific activity during different treatment which showed no significant differences between the varieties used. The in vitro bioavailability of iron and zinc were significantly improved as a result of soaking and germination treatments
East Asia Institute
The East Asia Institute is an independent think tank in Korea, founded in May 2002. The EAI strives to transform East Asia into a society of nations based on liberal democracy, market economy, open society, and peace. To this end, the EAI works to propagate liberal values and ideas including diversity, tolerance, accountability, and transparency through research, education, and international exchange. The EAI was established to pursue and develop innovative and fresh ideas. By attracting and cooperating with leading scholars and experts from the world, the EAI has functioned as a knowledge network generating creative policy ideas.The EAI endeavors to see that these ideas become a reality. In this way, we can prepare a bright world for our future generation. The EAI is rooted in the belief that knowledge and good ideas can change the world.https://repository.upenn.edu/aboutthinktanks/1017/thumbnail.jp
