This paper presents the design principles, implementation, and evaluation of the RETOS operating system which is specifically developed for micro sensor nodes. RETOS has four distinct objectives, which are to provide (1) a multithreaded programming interface, (2) system resiliency, (3) kernel extensibility with dynamic reconfiguration, and (4) WSN-oriented(More)
Three new (2-4) and one known (1) sphingolipid were identified in the MeOH extract of Bombycis Corpus 101A. Their structures were elucidated as (4E,2S,3R)-2-N-octadecanoyl-4-tetradecasphingenine (1), (4E,6E,2S,3R)-2-N-eicosanoyl-4,6-tetradecasphingadienine (2), (4E,2S,3R)-2-N-eicosanoyl-4-tetradecasphingenine (3), and(More)
— This paper introduces a component-based network management system for wireless sensor networks. The research is motivated by a variety of problems that occur due to the unpredictable behavior of wireless sensor networks. Once sensor nodes are deployed, the inner behavior of a sensor field can only be analyzed by monitoring incoming data packets at the(More)
Piwi-interacting RNAs (piRNAs) are recently discovered, endogenous small non-coding RNAs. piRNAs protect the genome from invasive transposable elements (TE) and sustain integrity of the genome in germ cell lineages. Small RNA-sequencing data can be used to detect piRNA activations in a cell under a specific condition. However, identification of cell(More)
The exponential increase of genomic data brought by the advent of the next or the third generation sequencing (NGS) technologies and the dramatic drop in sequencing cost have driven biological and medical sciences to data-driven sciences. This revolutionary paradigm shift comes with challenges in terms of data transfer, storage, computation, and analysis of(More)
MOTIVATION To understand the dynamic nature of the biological process, it is crucial to identify perturbed pathways in an altered environment and also to infer regulators that trigger the response. Current time-series analysis methods, however, are not powerful enough to identify perturbed pathways and regulators simultaneously. Widely used methods include(More)
Drought-stress can cause major economic loss and is a serious issue to address in agriculture. Defining the molecular pathways in how a plant responds to drought-stress may prove valuable in developing new drought-resistant plants. In this study, we identified several novel drought-responsive regulatory coding and noncoding transcripts in rice, Oryza sativa(More)
Drought tolerance is an important trait related to growth and yield in crop. Until now, drought related research has focused on coding genes. However, non-coding RNAs also respond significantly to environmental stimuli such as drought stress. Unfortunately, characterizing the role of siRNAs under drought stress is difficult since a large number of(More)
SUMMARY IEEE 802.16m is an advanced air interface standard which is under development for IMT-Advanced systems, known as 4G systems. IEEE 802.16m is designed to provide a high data rate and a Quality of Service (QoS) level in order to meet user service requirements, and is especially suitable for mobilized environments. There are several factors that have(More)
