This paper presents an efficient adaptive combination strategy for the distributed estimation problem over diffusion networks in order to improve robustness against spatial variation of signal and noise statistics network. The concept minimum variance unbiased is used derive proposed combiner a systematic way. mean, mean-square, steady-state performance analyses least-mean squares (LMS) algorithms with combiners are included stability convex rules proved. Simulation results show (i) that LMS...
Abstract The detection of visible damage (i.e., cracking, concrete spalling and crushing, reinforcement exposure, buckling fracture) plays a key role in postearthquake safety assessment reinforced (RC) building structures. In this study, novel approach based on computer‐vision techniques was developed for pixel‐level multicategory seismic RC components. A semantic segmentation database constructed from test photos structural Series datasets were generated the by applying image...
Cross entropy is a measure in machine learning and deep that assesses the difference between predicted actual probability distributions. In this study, we propose cross as performance evaluation metric for image classifier models apply it to CT classification of lung cancer. A convolutional neural network employed (DNN) classifier, with residual (ResNet) 50 chosen DNN archi-tecture. The data used comprise set. Two are built from datasets varying amounts data, cancer categorized into four...
This paper presents an efficient link probability control strategy for distributed estimation problems over probabilistic diffusion networks where the mean usage of communication resources is restricted. The proposed algorithm controls probabilities so that error minimized under given resource constraints. Simulation results show least-mean squares (LMS) with not only outperforms those static but also reduces amount communications among nodes.
This paper discusses "multi-tier mobile cloud computing" architecture, where small IT servers in users' proximity are utilized to execute a part of application processing. The way partitioning changes distribution processing loads and traffic, affects delay or battery usage. problem is that it unclear what partition brings better result. studies an abstract model execution multi-tier cloud, performance metrics, examines trade-offs among them. A prototype named Edge Accelerated Web Browsing...
Peptide hormones and neuropeptides constitute an important class of naturally occurring peptides that are generated from precursor proteins by limited proteolytic processing. An but unaddressed issue in peptidomics is to pin down novel bioactive a bulk peptide sequences provided tandem mass spectrometry. Here, we describe approach simultaneously screen for their target tissues. The principle behind this identify intact secretory have the ability raise intracellular calcium levels. In...
The Sparc64 VIIIfx eight-core processor, developed for use in petascale computing systems, runs at speeds of up to 2 GHz and achieves a peak performance 128 gigaflops while consuming as little 58 watts power. realizes six-fold improvement per watt over previous generation processors.
This is a reconnaissance report on the damage to buildings, bridges, and other structures caused by 2009 L'Aquila, Italy earthquake. The authors conducted site investigation during period of April 18–21, 2009. A detailed discussion facilities, as well possible mechanisms, presented. Geotechnical ground motions are also
Multi-access Edge Computing (MEC) can be defined as a model for enabling business oriented, cloud computing platform within multiple types of the access network (e.g., LTE, 5G, WiFi, FTTH, etc.) at close proximity subscribers to serve delay sensitive, context aware applications. To pull out most potential, MEC has designed infrastructure, support many kind IoT applications and their eco system, in addition sufficiently management mechanism. In this context, various research standardization...
X-linked sideroblastic anemia (XLSA), the most common form of congenital anemia, is caused by a germline mutation in erythroid-specific 5-aminolevulinate synthase (ALAS2) gene. In XLSA, defective heme biosynthesis leads to ring sideroblast formation because excess mitochondrial iron accumulation. this study, we introduced ALAS2 missense mutations on human umbilical cord blood-derived erythroblasts; hereafter, refer them as XLSA clones. clones that differentiated into mature erythroblasts...
Three major traditional Chinese medicines (TCM), Sho-saiko-To, Saiboku-To, and Sairei-To, consist of similar herbal prescriptions containing glycyrrhizin, which is a strong inhibitor 11 beta-hydroxysteroid dehydrogenase. We performed cross-over open trials in healthy subjects to clarify prednisolone pharmacokinetics on co-administration these preparations. All received single oral dose 10 mg before treatment with one the test After 2-week wash-out interval, they preparations for three days...
This paper presents an efficient adaptive combination strategy for diffusion algorithms over networks in order to improve the robustness against spatial variation of SNR network. The least-mean square (LMS) algorithm with proposed rule and its mean transient analysis are included. Simulation results show that LMS our combiners outperforms those existing static incremental algorithm.
Abstract. Tsunami fragility functions describe the probability of structural damage due to tsunami flow characteristics. Fragility developed from past events (e.g., 2004 Indian Ocean tsunami) are often applied directly, without modification, other areas at risk for purpose and loss estimations. Consequentially, estimates carry uncertainty disparities in construction standards coastal morphology between specific region which were originally derived where they being used. The main objective...
