Malaria burden on Bioko Island has decreased significantly over the past 15 years. The impact of interventions malaria prevalence, however, recently stalled. Here, we use data from island-wide, annual indicator surveys to investigate human movement patterns and their relationship Plasmodium falciparum prevalence. Using geostatistical mathematical modelling, find that off-island travel is more prevalent in around capital, Malabo. odds infection among travelers are higher than rest population....
We consider the incidence of text "reuse" by researchers, via a systematic pairwise comparison content all articles deposited to arXiv.org from 1991--2012. measure global frequencies three classes reuse, and how chronic reuse is distributed among authors in dataset. infer baseline for accepted practice, perhaps surprisingly permissive compared with other societal contexts, clearly delineated set aberrant authors. find negative correlation between amount reused an article its influence, as...
Newly available datasets present exciting opportunities to investigate how human population movement contributes the spread of infectious diseases across large geographical distances. It is now possible construct realistic models disease dynamics for purposes understanding global-scale epidemics. Nevertheless, a remaining unanswered question best leverage new data parameterize movement, and whether one's choice model impacts modeled outcomes. We adapt three well-studied dynamics,...
Abstract Background In parts of Africa, women who become widowed lose housing, bank accounts, and other property must re-marry to avoid extreme poverty. To re-marry, some are required undergo widow “cleansing”—condomless sex with a man removes “impurities” ascribed her from husband’s death—and “inherited” as wife brother-in-law. This study explores how HIV biomedical structural interventions could reduce HIV-related harms associated these practices. Methods We adapted EMOD-HIV, an...
We perform the analog to "water bell" experiments with granular jets. Rebounding from cylindrical targets, wide jets produce sheets or cones shapes that mimic a zero-surface-tension liquid. The jets' particulate nature appears when number of particles in cross section is decreased: emerging structures broaden, gradually disintegrating into diffuse sprays. experiment has counterpart behavior quark-gluon plasmas generated by colliding heavy ions. There, high collision density gives rise...
Mosquitoes are important vectors for pathogens that infect humans and other vertebrate animals. Some aspects of adult mosquito behavior ecology play an role in determining the capacity vector populations to transmit pathogens. Here, we re-examine factors affecting transmission by mosquitoes using a new approach. Unlike most previous models, this framework considers behavioral states state transitions through sequence activity bouts. We developed individual-based simulation models called...
The Ross-Macdonald model has exerted enormous influence over the study of malaria transmission dynamics and control, but it lacked features to describe parasite dispersal, travel, other important aspects heterogeneous transmission. Here, we present a patch-based differential equation modeling framework that extends with sufficient skill complexity support planning, monitoring evaluation for Plasmodium falciparum control. We designed generic interface building structured, spatial models based...
The effective bandwidth of a bus and external communication ports can be increased by using variant data compression techniques that compacts words instead streams. compaction is performed caching the high order bits into table sending index along with low bits. A coherent at receiving end expands word it original form. Compaction/expansion units placed between processor memory, local bus, devices access system bus. Simulations have shown over 90% all informative transferred sent in single...
To understand and model public health emergencies, epidemiologists need data that describes how humans are moving interacting across physical space. Such has traditionally been difficult for researchers to obtain with the temporal resolution geographic breadth is needed study, example, a global pandemic. This paper Colocation Maps, which spatial network datasets have developed within Meta's Data For Good program. These Maps estimate often people from different regions colocated: in...
This paper proposes a technique that enables performing multi-cycle (multiplication, division, square-root …) computations in single cycle. The is based on the notion of memoing: saving input and output previous calculations using if encountered again. especially suitable for Multi-Media (MM) processing. In MM applications local entropy data tends to be low which results repeated operations same datum.The inputs outputs assembly level are stored cache-like lookup tables accessed...
The HIV/AIDS epidemic remains critical in sub-Saharan Africa, with UNAIDS establishing "95-95-95" targets to optimize HIV care. Using the Zimbabwe Population-based Impact Assessment (ZIMPHIA) geospatial data, this study aimed identify patterns these and determinants impacting care continuum underserved Zimbabwean communities. Analysis techniques, including Gaussian kernel interpolation, optimized hotspot, multivariate k-means clustering, were utilized establish spatial cluster regional...
A majority of the papers published in leading computer architecture conferences use SPEC CPU2000, or its predecessor CPU95, which has become de facto standard for measuring processor and/or memory-hierarchy performance. However, most cases a subset suite's benchmarks are simulated. For example: 27 were ISCA 2002, 16 used CINT2000, 4 whole suite, and only 3 explained their omissions.This paper quantifies extent this phenomenon ISCA, Micro, HPCA conferences: 173 surveyed, 115 from CINT, but 23...

For several decades, computer scientists have been arguing which mean is more appropriate for summarizing performance: the harmonic or geometric. We show that many test cases used in past to discredit one other are either artificial incidental. Changing only of benchmarks may result totally different conclusions.In addition, we conclude SPEC CPU2000 benchmark suite, choice averaging has very little influence on relative standing machines. Therefore, decision purchase system rather then...
A facility for x-ray computed microtomography (CMT) is operating as a national user earth and environmental sciences research on the bending magnet beamline at GeoSoilEnviroCARS sector Advanced Photon Source (APS). We present an analysis of source noise in reconstructed data, compared to data similar samples from another instrument. also report careful characterization CCD detector, new highspeed collection strategies, applications high-pressure tomography.
The majority of papers published by computer architecture conferences use the SPEC benchmark suite to measure performance. However, many researchers only a subset suite. What's more surprising is how few people explain their reasons for subsetting.
Wires shrink less efficiently than transistors. Smaller dimensions increase relative delay and the probability of crosstalk. Solutions to this problem include adding additional latency with pipelining, using "fat wires" at higher metal levels, advances in process material technology. We propose a stopgap solution by applying decade old technique called bus-expanding problem. By exploiting low spatial temporal entropy data it is possible transfer m bits over n-bit wide bus single cycle (m > n...
Abstract Background Malaria elimination is the goal for Bioko Island, Equatorial Guinea. Intensive interventions implemented since 2004 have reduced prevalence, but progress has stalled in recent years. A challenge been malaria infections residents acquired during travel to mainland The present article quantifies how off-island contributes remaining prevalence on and investigates potential role of a pre-erythrocytic vaccine making further towards elimination. Methods transmission Island was...
In sub-Saharan Africa, HIV/AIDS remains a leading cause of death. The UNAIDS established the '95-95-95' targets to improve HIV care continuum outcomes. Using geospatial data from Zambia Population-based Impact Assessment (ZAMPHIA), this study aims investigate patterns in indicators and individual-level determinants that impede vulnerable communities, providing insights into factors associated with gaps.
Testing for correctness and reliability is a major challenge in the development deployment of cloud computing platforms. composed hundreds to thousands servers often cost-prohibitive because extensive amount hardware required. Simulation emulation, i.e., traditional alternatives hardware, are too abstract or slow testing production code environments with many servers. We propose approach that combines simulation emulation simulator runs on single processor yet enables management software as...
