Sarcopenia And Current Research Using Ames Dwarf Mice: A Research Study, Amanda Sodemann Jan 2014

Sarcopenia And Current Research Using Ames Dwarf Mice: A Research Study, Amanda Sodemann

Physical Therapy Scholarly Projects

This research project focused on the differences observed in muscle fiber composition and surface area between wild type mice and Ames dwarf mice as they aged. A mouse model was utilized because the skeletal muscle framework of mice closely resembles that of human muscle; thus, the observations seen within the mice may also be seen within humans as they age. Comparisons between the wild type and dwarf mice include a smaller cross-sectional muscle area in a dwarf mouse and no drastic change in the percentages of fast and slow twitch muscle fibers as the dwarf mouse ages. Furthermore, differences in …

Tropical Pacific Influence On The Source And Transport Of Marine Aerosols To West Antarctica, Alison S. Criscitiello, Sarah B. Das, Kristopher B. Karnauskas, Matthew J. Evans, Karen E. Frey, Ian Joughin, Eric J. Steig, Joseph R. Mcconnell, Brooke Medley Jan 2014

Tropical Pacific Influence On The Source And Transport Of Marine Aerosols To West Antarctica, Alison S. Criscitiello, Sarah B. Das, Kristopher B. Karnauskas, Matthew J. Evans, Karen E. Frey, Ian Joughin, Eric J. Steig, Joseph R. Mcconnell, Brooke Medley

Geography

The climate of West Antarctica is strongly influenced by remote forcing from the tropical Pacific. For example, recent surface warming over West Antarctica reflects atmospheric circulation changes over the Amundsen Sea, driven by an atmospheric Rossby wave response to tropical sea surface temperature (SST) anomalies. Here, it is demonstrated that tropical Pacific SST anomalies also influence the source and transport of marine-derived aerosols to theWest Antarctic Ice Sheet. Using records from four firn cores collected along the Amundsen coast of West Antarctica, the relationship between sea ice-modulated chemical species and large-scale atmospheric variability in the tropical Pacific from 1979 to …

Geodesy- And Geology-Based Slip-Rate Models For The Western United States (Excluding California) National Seismic Hazard Maps, Mark D. Petersen, Yuehua Zeng, Kathleen M. Haller, Robert Mccaffrey, William C. Hammond, Peter Bird, Morgan Moschetti, Zheng-Kang Shen, Jayne Bormann, Wayne R. Thatcher

Geology Faculty Publications and Presentations

The 2014 National Seismic Hazard Maps for the conterminous United States incorporate additional uncertainty in fault slip-rate parameter that controls the earthquake-activity rates than was applied in previous versions of the hazard maps. This additional uncertainty is accounted for by new geodesy- and geology-based slip-rate models for the Western United States. Models that were considered include an updated geologic model based on expert opinion and four combined inversion models informed by both geologic and geodetic input. The two block models considered indicate significantly higher slip rates than the expert opinion and the two fault-based combined inversion models. For the hazard …

Fifty-one undergraduate students enrolled in a general education biology course at a southeastern university participated in this three-week experimental study. The researcher used the Metacognitive Self-Regulation Scale of the Motivated Strategies for Learning …


Analysis And Optimization Of A Protocol For Mobile Element Discovery In Sensor Networks, Francesco Restuccia, Giuseppe Anastasi, Marco Conti, Sajal K. Das Jan 2014

Analysis And Optimization Of A Protocol For Mobile Element Discovery In Sensor Networks, Francesco Restuccia, Giuseppe Anastasi, Marco Conti, Sajal K. Das

Computer Science Faculty Research & Creative Works

Recent studies have demonstrated that mobile elements (MEs) are an efficient solution to help decrease dramatically energy consumption in wireless sensor networks (WSNs). However, in most of cases, sensors use duty cycle schemes to save energy, and unless the ME mobility pattern is deterministic, each sensor node has to discover the presence of the ME in the nearby area before starting to exchange data with it. Therefore, in such wireless sensor networks with mobile elements (in short, WSN-MEs), the definition and analysis of a protocol for efficient ME discovery becomes of fundamental importance. In this paper, we propose an extensive …

Impact Of Location History Collection Schemes On Observed Human Mobility Features, Alicia Rodriguez-Carrion, Sajal K. Das, Celeste Campo, Carlos Garcia-Rubio

Computer Science Faculty Research & Creative Works

Human mobility knowledge is key for urban planning or mobility model's design. Therefore, estimating reliable mobility parameters is crucial to lay an unbiased foundation. However, most works estimating such features rely on datasets made up of the history of mobile network cells where the user is located when she makes active use of the network, known as Call Data Records (CDRs), or every time their device connects to a new cell, without taking into account cell changes not caused by movement. Could we accurately characterize human mobility with such datasets? In this work we consider three approaches to collect network-based …

Exploring Optimization And Caching For Efficient Collection Operations, Venkata Krishna Suhas Nerella, Swetha Surapaneni, Sanjay K. Madria, Thomas Weigert

Computer Science Faculty Research & Creative Works

Many large programs operate on collection types. Extensive libraries are available in many programming languages, such as the C++ Standard Template Library, which make programming with collections convenient. Extending programming languages to provide collection queries as first-class constructs in the language would not only allow programmers to write queries explicitly in their programs but it would also allow compilers to leverage the wealth of experience available from the database domain to optimize such queries. This paper describes an approach to reduce the run time of programs involving explicit collection queries by performing run time query optimization that is effective for …

Qos Aware Geographic Opportunistic Routing In Wireless Sensor Networks, Long Cheng, Jianwei Niu, Jiannong Cao, Sajal K. Das, Yu Gu Jan 2014

Qos Aware Geographic Opportunistic Routing In Wireless Sensor Networks, Long Cheng, Jianwei Niu, Jiannong Cao, Sajal K. Das, Yu Gu

Computer Science Faculty Research & Creative Works

QoS routing is an important research issue in wireless sensor networks (WSNs), especially for mission-critical monitoring and surveillance systems which requires timely and reliable data delivery. Existing work exploits multipath routing to guarantee both reliability and delay QoS constraints in WSNs. However, the multipath routing approach suffers from a significant energy cost. In this work, we exploit the geographic opportunistic routing (GOR) for QoS provisioning with both end-to-end reliability and delay constraints in WSNs. Existing GOR protocols are not efficient for QoS provisioning in WSNs, in terms of the energy efficiency and computation delay at each hop. To improve the …

Complexity Of The Soundness Problem Of Workflow Nets, Guan Jun Liu, Jun Sun, Yang Liu, Jin Song Dong Jan 2014

Complexity Of The Soundness Problem Of Workflow Nets, Guan Jun Liu, Jun Sun, Yang Liu, Jin Song Dong

Research Collection School Of Computing and Information Systems

Classical workflow nets (WF-nets for short) are an important subclass of Petri nets that are widely used to model and analyze workflow systems. Soundness is a crucial property of workflow systems and guarantees that these systems are deadlock-free and bounded. Aalst et al. proved that the soundness problem is decidable for WF-nets and can be polynomially solvable for free-choice WF-nets. This paper proves that the soundness problem is PSPACE-hard for WF-nets. Furthermore, it is proven that the soundness problem is PSPACE-complete for bounded WF-nets. Based on the above conclusion, it is derived that the soundness problem is also PSPACE-complete for …


The Challenge Of Continuous Mobile Context Sensing, Rajesh Krishna Balan, Youngki Lee, Kiat Wee Tan, Archan Misra Jan 2014

The Challenge Of Continuous Mobile Context Sensing, Rajesh Krishna Balan, Youngki Lee, Kiat Wee Tan, Archan Misra

Research Collection School Of Computing and Information Systems

In this paper, we highlight the challenge of continuously sensing context data from mobile phones. In particular, we show that the energy cost of this type of continuous sensing is extremely high if a) accuracy is desired, and b) power optimisations do not work well if multiple tasks are sensing concurrently. Our results are derived from our experience in building the LiveLabs context sensing platform. We present results for different types of sensing tasks; ranging from simple sensing using just one sensor all the way to multi-sensor sensing performed by concurrent high-level tasks. We end with a discussion of the …


Privacy-Preserving Ad-Hoc Equi-Join On Outsourced Data, Hwee Hwa Pang, Xuhua Ding Jan 2014

Privacy-Preserving Ad-Hoc Equi-Join On Outsourced Data, Hwee Hwa Pang, Xuhua Ding

Research Collection School Of Computing and Information Systems

In IT outsourcing, a user may delegate the data storage and query processing functions to a third-party server that is not completely trusted. This gives rise to the need to safeguard the privacy of the database as well as the user queries over it. In this article, we address the problem of running ad hoc equi-join queries directly on encrypted data in such a setting. Our contribution is the first solution that achieves constant complexity per pair of records that are evaluated for the join. After formalizing the privacy requirements pertaining to the database and user queries, we introduce a …

In addition to the problem formulation …


Online Multiple Kernel Similarity Learning For Visual Search, Hao Xia, Chu Hong Hoi, Rong Jin, Peilin Zhao Jan 2014

Online Multiple Kernel Similarity Learning For Visual Search, Hao Xia, Chu Hong Hoi, Rong Jin, Peilin Zhao

Research Collection School Of Computing and Information Systems

Recent years have witnessed a number of studies on distance metric learning to improve visual similarity search in content-based image retrieval (CBIR). Despite their successes, most existing methods on distance metric learning are limited in two aspects. First, they usually assume the target proximity function follows the family of Mahalanobis distances, which limits their capacity of measuring similarity of complex patterns in real applications. Second, they often cannot effectively handle the similarity measure of multimodal data that may originate from multiple resources. To overcome these limitations, this paper investigates an online kernel similarity learning framework for learning kernel-based proximity functions …


Cross-Domain Password-Based Authenticated Key Exchange Revisited, Liqun Chen, Hoon Wei Lim, Guomin Yang Jan 2014

Cross-Domain Password-Based Authenticated Key Exchange Revisited, Liqun Chen, Hoon Wei Lim, Guomin Yang

Research Collection School Of Computing and Information Systems

We revisit the problem of secure cross-domain communication between two users belonging to different security domains within an open and distributed environment. Existing approaches presuppose that either the users are in possession of public key certificates issued by a trusted certificate authority (CA), or the associated domain authentication servers share a long-term secret key. In this article, we propose a generic framework for designing four-party password-based authenticated key exchange (4PAKE) protocols. Our framework takes a different approach from previous work. The users are not required to have public key certificates, but they simply reuse their login passwords, which they share …
