Artemis simulations were run using the development branch of artemis https://github.com/ECP-WarpX/artemis
Some simulations in this paper were performed with different commit hashes of artemis and amrex, however, the input files should still work with the most recent development branch of artemis.
In the attached tar file, the input files, data, and scripts used to analyse simulation results shown in Figures 1, 2, 3, 4, and 6 of the paper are provided. To run the simulations on perlmutter GPUs, the code is compiled with USE_GPU=TRUE and USE_LLG=FALS
Importance of Glutamate Dehydrogenase (GDH) in Clostridium difficile Colonization In Vivo
No full textCitation: Girinathan, B. P., Braun, S., Sirigireddy, A. R., Lopez, J. E., & Govind, R. (2016). Importance of Glutamate Dehydrogenase (GDH) in Clostridium difficile Colonization In Vivo. Plos One, 11(7), 18. doi:10.1371/journal.pone.0160107Clostridium difficile is the principal cause of antibiotic-associated diarrhea. Major metabolic requirements for colonization and expansion of C. difficile after microbiota disturbance have not been fully determined. In this study, we show that glutamate utilization is important for C. difficile to establish itself in the animal gut. When the gluD gene, which codes for glutamate dehydrogenase (GDH), was disrupted, the mutant C. difficile was unable to colonize and cause disease in a hamster model. Further, from the complementation experiment it appears that extracellular GDH may be playing a role in promoting C. difficile colonization and disease progression. Quantification of free amino acids in the hamster gut during C. difficile infection showed that glutamate is among preferred amino acids utilized by C. difficile during its expansion. This study provides evidence of the importance of glutamate metabolism for C. difficile pathogenesis
p-Pheneylendiamine functionalized rGO/Si heterostructure Schottky junction for UV photodetectors
No full textIn this work, we report on p-Phenylenediamine (PPD) functionalized reduced graphene oxide (rG0)/Si hybrid-structure designed for UV photodetector applications (PD). The hybrid-structure was characterized by using Fourier Transform-infrared spectroscopy, X-ray photoelectron spectroscopy to confirm the formation of nano-hybrid structure and the experimental results confirmed the covalent bond between rGO and PPD. The diode parameters such as barrier height, series resistance, and ideality factor were estimated for both PPD functionalized rGO (PrGO)/Si and rGO/Si heterostructure by using I-V characteristics. The time-resolved photocurrent spectroscopy used to examine the photoresponse properties of both PrGO/Si and rGO/Si samples with UV light (lambda = 382 nm). The experimental results showed that PrGO/Si exhibited significant UV photoresponse than that of rGO/Si PD. The PrGO/Si heterostructure device exhibited photoresponsivity of 1.4 x 10(-3) A/W, which is 15 times higher than rGO/Si. The high photoresponse was attributed to the synergistic effects originated from the charge transfer between PPD and rGO. The results proved that PrGO is a promising material for high response photodetector applications.
Factors associated with prehospital delay in patients with acute stroke in South India
No full textBackground: Early hospital presentation is critical in the management of acute ischemic stroke. The effectiveness of stroke treatment is highly dependent on the amount of time lapsed between onset of symptoms and treatment. This study was aimed to identify the factors associated with prehospital delay in patients with acute stroke. Material and Methods: A cross-sectional descriptive study was conducted in Sri Ramachandra University Hospital, India. A total of 210 patients hospitalized in the stroke unit were included. Patients' data were obtained by interviewing the patient and/or accompanying family member and by reviewing their medical records using a standard questionnaire. Associations were determined between prehospital delay (≥4.5 h) and variables of interest by using univariate and multivariate logistic regression analyses. Results: The prehospital delay was observed in 154 patients (73.3%) and the median prehospital delay was 11.30 h. The following are the factors significantly (P < 0.05) attributed for the delay in presenting to the hospital: contextual factors like using public transport (bus), taxi, time of onset of symptoms, 7 pm–3 am; family history of stroke, perceived cognitive and behavioral factors like, wishing or praying for the symptoms to subside on its own, hesitation to travel due to long distance, delay in arranging transport, and arranging money for admission and wasting time by shopping for general practitioners, nursing homes, and hospitals. The presence of stroke symptom, headache, significantly decreased the prehospital delay. Conclusions: Prehospital delay is high in South India and influenced by clinical, contextual, and cognitive/behavioral factors

Camel Streptococcus agalactiae populations are associated with specific disease complexes and acquired the tetracycline resistance gene tetM via a Tn916-like element
No full textCamels are the most valuable livestock species in the Horn of Africa and play a pivotal role in the nutritional sustainability for millions of people. Their health status is therefore of utmost importance for the people living in this region. Streptococcus agalactiae, a Group B Streptococcus (GBS), is an important camel pathogen. Here we present the first epidemiological study based on genetic and phenotypic data from African camel derived GBS. Ninety-two GBS were characterized using multilocus sequence typing (MLST), capsular polysaccharide typing and in vitro antimicrobial susceptibility testing. We analysed the GBS using Bayesian linkage, phylogenetic and minimum spanning tree analyses and compared them with human GBS from East Africa in order to investigate the level of genetic exchange between GBS populations in the region. Camel GBS sequence types (STs) were distinct from other STs reported so far. We mapped specific STs and capsular types to major disease complexes caused by GBS. Widespread resistance (34%) to tetracycline was associated with acquisition of the tetM gene that is carried on a Tn916-like element, and observed primarily among GBS isolated from mastitis. The presence of tetM within different MLST clades suggests acquisition on multiple occasions. Wound infections and mastitis in camels associated with GBS are widespread and should ideally be treated with antimicrobials other than tetracycline in East Africa
Urban Asymmetries Ciudad Juarez, Mexico: Designing A Transferium ...... A point of Exchange
No full textThe MSc. graduation project dealt with understanding the implications of Neo liberal policies on the city of Juarez which lies on the US - Mexico border. In 2009 Ciudad Juarez was rated as “the most violent zone in the world outside of declared war zones” due to high crime rates, femisides, homicides, corruption, drug trafficking and multiple other problems. The city is also presently facing massive exodus and the abandoning of large portions of its housing stock due to the increase in violence and a prevailing low intensity war between the state and the drug cartels. The reasons for this asymmetrical development are multiple and point towards a complex mesh of forces that transgress the scope of the built environment. They encompass entangled dimensions of political economy and socio-economic developments, which eventually affect the built environment. With this background a six month intense research was carried out and a counter proposal group strategy was proposed on a prototype site Riberas Del bravo and eventually an Urban & architectural intervention was designed. Thus as part of my graduation project I designed a collective transport system comprising of three design elements the Transferium hub, the bus stops and the routes on the prototype site. The core design idea dealt with developing a time based concept, that allowed hybridization of the programme and hence catered to both peak and anti-peak hour differently. Firstly a strong east west axis was developed to regulate and accentuate the flow of people along the canal & public promenade proposed as part of the group strategy. These east west axis were flanged by three pavilions serving the Transferium and Community center on the two edges and a multipurpose market space at the center. The central multipurpose market space manifested itself further as Hawking zone courtyard, Mobile Market courtyard and Permanent Market. During the peak hour the Transferium expanded into the central multipurpose space and during the anti-peak hour the community market/activities expanded into the multipurpose space. Thus depending on the flow of vehicles the central multipurpose space grew or condensed in size catering to different activities.Urban AsymmetriesDelft School of DesignArchitectur
