Using Intuitionistic Fuzzy Set for Anomaly Detection of Network Traffic From Flow Interaction (2018)

We present a method to detect anomalies in time series of flow interaction patterns. There are many existing methods for anomaly detection in network traffic, such as the number of packets. However, there is no established method to detect anomalies in time series of flow interaction patterns that can be represented as complex network. First, based on the proposed multivariate flow similarity method on temporal locality, a complex network model (MFS-TL) is constructed to describe the interactive behaviors of traffic flows. After analyzing the relationships between MFS-TL characteristics, temporal locality window, and multivariate flow similarity critical threshold, an approach for parameters determination was established. Observed the evolution of MFS-TL characteristics, three non-deterministic correlations were defined for network states (i.e., normal or abnormal). Furthermore, intuitionistic fuzzy set (IFS) is introduced to quantify three non-deterministic correlations, and an anomaly detection method is put forward for single characteristic sequence. In order to build an objective IFS, we design a Gaussian distribution-based membership function with a variable hesitation degree. To determine the mapping of IFS's clustering intervals to network states, a distinction index is developed. Furthermore, an IFS ensemble method (IFSE-AD) is proposed to eliminate the impacts of the inconsistent about MFS-TL characteristic to network state and to improve detection performance. Finally, we carried out extensive experiments on some network traffic datasets, and the results validate the effectiveness of our method and demonstrate the superiority of IFSE-AD to state-of-the-art approaches.
Determination of rigid-body pose from imprecise point position measurements (2011)

The determination of a rigid-body position and orientation from the position of a number of its points is one of the fundamental problems in kinematics. This problem arises in robotics, biomechanics, automatic guided vehicles, real-time control of space structures, etc. Under ideal conditions, it is possible to apply classical methods to find a body's position and orientation. However, in the presence of noise, these methods yield results that are unreliable and inconsistent. Two existing and a new method for determining position and orientation from noisy point coordinate data are presented. The theoretical analysis of the methods combined with an extensive simulation process led to conclusions about their behavior in different situations. The proposed method yields better orientation estimates than the other two methods, yielding reliable results both for absolute and relative position measurements and for low and high noise levels.
A new rapid differentiating solubility test for hemoglobin S. (1975)

A new test for sickling hemoglobin, SickleQuikTM, has been developed which has definitive advantages over existing turbidity tests. This test utilizes a biphasic liquid reagent system provided in individualized, ready-to-use reaction tubes which are stable at room temperature. The test differentiates homozygous from heterozygous S samples in less than eight minutes. Results are based on the color of a layer formed at the organic-aqueous interface and the color of the lower aqueous phase. Of more than 900 samples tested in independent laboratories, no false positive or false negative results occurred.
Learning based link adaptation in multiuser MIMO-OFDM (2013)

Link adaptation in multiple user multiple-input multiple-output orthogonal frequency division multiplexing communication systems is challenging because of the coupling between user selection, mode selection, precoding, and equalization. In this paper, we present a methodology to perform link adaptation under this multiuser setting, focusing on the capabilities of IEEE 802.11ac. We propose to use a machine learning classifier to solve the problem of selecting a proper modulation and coding scheme, combined with a greedy algorithm that performs user and spatial mode selection. We observe that our solution offers good performance in the case of perfect channel state information or high feedback rate, while those scenarios with less feedback suffer some degradation due to inter-user interference.
Bio-inspired resin acid-derived materials as anti-bacterial resistance agents with unexpected activities (2014)

Methicillin-resistant Staphylococcus aureus (MRSA), a complex of multidrug resistant Gram-positive bacterial strains, has proven especially problematic in both hospital and community-settings, resulting in increased mortality rates and hospitalization costs. Emergence of resistance even to vancomycin, the standard reference for MRSA treatment, builds up pressure for the search of novel alternatives. We report potent natural resin acid-based cationic antimicrobial compounds and polymers that exhibit surprising antimicrobial activity against a range of MRSA strains, yet are largely non-toxic against mammalian cells. Molecular dynamics simulations and dye-leakage assays with anionic phospholipid membrane mimics of bacteria demonstrate a membrane-lysing effect induced by unique fused ring structures of resin acids that may constitute the principal mechanism of action for selective lysis of bacterial cells over mammalian cells. Our antimicrobial materials are derived from an unlikely yet abundant natural source, and offer a novel alternative to currently-used approaches.
Surface decoration of carbon nanotubes and mechanical properties of cement/carbon nanotube composites (2008)

The present study investigated the effects of the method of surface decoration on the wetability of multi-walled carbon nanotubes (MWCNTs) and the mechanical properties of the cement paste incorporating these dispersions. The results showed that stable and homogenous dispersions of MWCNTs in water can be obtained by using surface functionalisation combined with decoration using polyacrylic acid polymers. The cement paste specimens incorporating these dispersions revealed good workability and an increase in the compressive strength of nearly 50% even with only a small addition of the MWCNTs, namely 0·045–0·15% of the cement weight. These results indicate the existence of chemical bonds between the OH groups of the functionalised MWCNTs and probably the CSH phase of the cement matrix, which enhanced the transfer of stresses. A second method that was studied included decoration of MWCNTs with polyacrylic acid polymers and gum Arabic. These dispersions appeared to be homogeneous only for approximately 2 h after which a progressive sedimentation occurred. Good workability was found for the cement pastes produced with all of the dispersions; the only significant difference being the slower hydration of the cement incorporating gum Arabic. The mechanical properties of the cement pastes incorporating MWCNTs treated with polyacrylic polymers were unchanged.

Proportional Disk I/O Bandwidth Management for Server Virtualization Environment (2008)

Many virtual machines are operated concurrently on a same physical machine. And service running on each virtual machine has different I/O requirement and priority. But, we can't guarantee that it has proper I/O bandwidth, because the I/O of virtual machine is treated as that of a process in normal system and there is no means to manage the I/O bandwidth for virtual machine. Therefore, we are hard to allocate I/O bandwidth to several virtual machines equally or discriminately. To solve the upper described problems, we propose a virtual machine-aware proportional share queuing scheduler, VM-PSQ, in server virtualization environment. To do that, we designed virtual machine unit scheduler and adopted the concept of time slice and schedule token to support the proportional share of I/O bandwidth. It recognizes each virtual machine I/O as independent system I/O. It enables us to allocate I/O bandwidth among many virtual machines equally or discriminately according to service priority or I/O requirement. This can make a good use of limited I/O bandwidth and guarantee the performance of specific virtual machine.

Mechanism of block by ZD 7288 of the hyperpolarization-activated inward rectifying current in guinea pig substantia nigra neurons in vitro (1995)

1. The effects of the novel bradycardic agent 4-(N-ethyl-N-phenylamino)-1,2-dimethyl-6-(methylamino) pyrimidinium chloride (ZD 7288) (Zeneca) were investigated on the hyperpolarization-activated cationic current (Ih) in guinea pig substantia nigra pars compacta neurons in vitro, using a single-microelectrode current-clamp/voltage-clamp technique. 2. Under current-clamp conditions, injection of large negative current pulses (0.1-0.5 nA, 400 ms) evoked a slow depolarizing "sag" in the electrotonic potential due to activation of the slow inward (anomalous) rectifier. In voltage-clamp recordings, hyperpolarizing voltage steps from a holding potential of -60 mV (close to resting potential) elicited slow inward current relaxations with kinetic properties similar to those seen for other neuronal Ihs. 3. ZD 7288 (10-100 microM) produced a consistent abolition of the electrotonic potential sag with no effect on membrane potential or spike properties. Under voltage clamp, Ih amplitude was clearly reduced in a time- and concentration-dependent manner (apparent half-maximum blocking concentration = 2 microM); full block of Ih was typically achieved after 10-15 min of exposure to 50 microM ZD 7288, with no significant recovery observed after 1 h of washing. 4. A similar (although more rapid) block of Ih was seen after application of 3-5 mM Cs+ (partially reversible after 30 min of washing). 5. Partial block of Ih by 10 microM ZD 7288 was accompanied by a reduction in the maximum amplitude of the Ih activation curve, a small negative shift in its position on the voltage axis, and a linearization of the steady-state current-voltage relationship. The estimated Ih reversal potential, however, remained unaffected. 6. In 10 microM ZD 7288, the time course of Ih activation and deactivation was significantly slowed (within the range of -70 to -120 mV for the activation time constant and -70 to -90 mV for the inactivation time constant). 7. Blockade of Ih by ZD 7288 or Cs+ was independent of prior Ih activation (i.e., non-use dependent). 8. Intracellular loading with ZD 7288 also abolished the sag in the electrotonic voltage response and Ih relaxations, suggesting an intracellular site of action. By contrast, intracellular Cs+ had no effect on Ih properties. 9. Block of Ih by ZD 7288 (but not Cs+) was relieved by prolonged cell hyperpolarization, manifested as a slowly developing (half-time approximately 20 s) inward current at a holding potential of -100 mV. 10. We propose that ZD 7288, when applied externally, may behave as a "lipophilic" quaternary cation, capable of passing into the cell interior to block Ih channels in their closed state; this compound may thus prove a useful research tool, in place of Cs+, for studying the properties and significance of Ih currents in controlling neuronal function.
Induction of nitrate uptake in maize roots: expression of a putative high-affinity nitrate transporter and plasma membrane H+-ATPase isoforms (2003)

An investigation was carried out to assess the effect of nitrate supply on the root plasma membrane (PM) H+-ATPase of etiolated maize (Zea mays L.) seedlings grown in hydroponics. The treatment induced higher uptake rates of the anion and the expression of a putative high-affinity nitrate transporter gene (ZmNRT2.1), the first to be identified in maize. Root PM H+-ATPase activity displayed a similar time-course pattern as that of net nitrate uptake and investigations were carried out to determine which of the two isoforms reported to date in maize, MHA1 and 2, responded to the treatment. MHA1 was not expressed under the conditions analysed. Genome analysis revealed that MHA2, described as the most abundant form in all maize tissues, was not present in the maize hybrid investigated, but a similar form was found instead and named MHA3. A second gene (named MHA4) was also identified and partially sequenced. Both genes, classified as members of the PM H+-ATPase subfamily II, responded to nitrate supply, although to different degrees: MHA4, in particular, proved more sensitive than MHA3, with a greater up- and down-regulation in response to the treatment. Increased expression of subfamily II genes resulted in higher steady-state levels of the enzyme in the root tissues and enhanced ATP-hydrolysing activity. The results support the idea that greater proton-pumping activity is required when nitrate inflow increases and suggest that nitrate may be the signal triggering the expression of the two members of PM H+-ATPase subfamily II.

Novel genetic association between the corneodesmosin (MHC S) gene and susceptibility to psoriasis (1999)

Psoriasis is an inflammatory skin disease of unknown origin, but with a clear genetic component. The strongest genetic association has been found with the major histocompatibility complex (MHC) region, and specifically between susceptibility to familial early onset psoriasis and human leukocyte antigen (HLA)-Cw6. The basis of this association of the HLA-C locus with disease pathogenesis is, however, not clear, and it is possible that other genes, or a combination of genes, in the HLA region are of functional importance. The MHC S gene is expressed specifically in keratinocyte differentiation and, being located 160 kb telomeric of HLA-C, is a plausible candidate gene. We analysed the allelic distribution of two polymorphisms in the MHC S gene (at +619 and +1243) in a case-control association study. We could confirm a significant association between psoriasis and HLA-Cw6 [odds ratio (OR) = 7.75]. No association was found between disease (or any subtypes) and the MHC S gene polymorphism at position +619, despite its close proximity to HLA-C and the strong linkage disequilibrium between the loci. However, a significant trend with the rarer allele at MHC S (+1243) and psoriasis was detected in the overall data set (OR = 2. 66; P = 2 [times] 10(-)9). This effect was most pronounced in the type 1a (early onset) psoriatics (OR = 3.43). Furthermore, homozygosity for the associated allele at MHC S (+1243) increased the risk of disease over that for carriage of HLA-Cw6 alone (OR = 9. 38), suggesting that allele 2 of MHC S (+1243) provides an additional risk in psoriasis susceptibility. The strong association found here, coupled with the biological involvement of the MHC S gene product corneodesmosin in skin physiology, implicates this locus (or a haplotype across HLA-C and MHC S ) in the impaired desquamation characteristic of psoriasis.
High-performance tantalum oxide capacitors fabricated by a novel reoxidation scheme (1990)

High-performance tantalum oxide capacitors with excellent reliability that were developed by a two-step oxidation scheme are discussed. An anodic reoxidation process is applied to the reactively sputter-deposited tantalum oxide films to make the densified oxide structure. The electrical and physical properties as well as the reliability of these two-step oxidized sputtered/anodized tantalum oxide films are shown to be much superior to those of conventional tantalum oxide films prepared by either anodization or sputtering alone. Capacitors made of the sputtered/anodized tantalum oxide film have greatly improved electrical properties and better reliability than anodized or sputtered tantalum oxide capacitors and are very useful for applications to high-capacity storage capacitors in future high-density VLSI memories.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Association between methylenetetrahydrofolate reductase (MTHFR) polymorphisms and susceptibility to Graves' ophthalmopathy (2016)

The pathogenesis of Graves' ophthalmopathy (GO) remains to be entirely elucidated. The present study aimed to determine the association between phenotypic expression of the MTHFR gene and susceptibility to GO in patients with Graves' disease (GD). A prospective case‑controlled study was conducted with 122 patients with GD and GO (n=72) or without GO (n=50) and 100 healthy controls in South Korea. Patient history, including smoking, nutritional status, thyroid function and antithyroid antibodies were investigated and clinical activity score, VISA classification (which includes vision, inflammation, strabismus and appearance/exposure) and orbit computed tomography were evaluated. Fasting plasma total homocysteine (tHcy) concentration was measured, and genotype analysis of the MTHFR gene was conducted. The TT homozygous genotype was associated with a two‑fold increased risk of GO [adjusted odds ratio (AOR), 2.19; 95% confidence interval (CI), 0.78‑6.14]. However, this result was not significant. The TT genotype significantly increased the risk of GO compared with that in healthy controls (AOR, 2.92; 95% CI, 1.11‑7.65). The MTHFR 677CT/1298AA genotype decreased the risk of GO in patients with GD (AOR, 0.26; 95% CI, 0.08‑0.91). tHcy levels in patients with GD without GO were significantly higher than in patients with GO, however, they were within the normal limit. The current study identified an association between MTHFR polymorphisms and GO. These results will aid understanding of the pathogenesis of GO and facilitate development of genetic therapeutic strategies.
Expression Strategy of the Potato Virus X Triple Gene Block (1991)

The mode of expression of the overlapping genes of the triple block positioned internally in potato virus X (PVX) RNA was examined. The results of In vitro translation of synthetic RNA transcripts and natural PVX-specific methylmercuric hydroxide-denatured dsRNAs suggest that the 25K protein is expressed as a single translation product of the 2.1 kb subgenomic (sg) RNA and that both the 12K and 8K proteins are expressed from the same 1.4 kb sgRNA.
Thermal effects on the wake of a heated circular cylinder operating in mixed convection regime (2011)

Abstract The thermal effects on the wake flow behind a heated circular cylinder operating in the mixed convection regime were investigated experimentally in the present study. The experiments were conducted in a vertical water channel with the heated cylinder placed horizontally and the flow approaching the cylinder downwards. With such a flow arrangement, the direction of the thermally induced buoyancy force acting on the fluid surrounding the heated cylinder would be opposite to the approach flow. During the experiments, the temperature and Reynolds number of the approach flow were held constant. By adjusting the surface temperature of the heated cylinder, the corresponding Richardson number ( $\mathit{Ri}= \mathit{Gr}/ {\mathit{Re}}^{2} $ ) was varied between 0.0 (unheated) and 1.04, resulting in a change in the heat transfer process from forced convection to mixed convection. A novel flow diagnostic technique, molecular tagging velocimetry and thermometry (MTV&T), was used for qualitative flow visualization of thermally induced flow structures and quantitative, simultaneous measurements of flow velocity and temperature distributions in the wake of the heated cylinder. With increasing temperature of the heated cylinder (i.e. Richardson number), significant modifications of the wake flow pattern and wake vortex shedding process were clearly revealed. When the Richardson number was relatively small ( $\mathit{Ri}\leq 0. 31$ ), the vortex shedding process in the wake of the heated cylinder was found to be quite similar to that of an unheated cylinder. As the Richardson number increased to ${\ensuremath{\sim} }0. 50$ , the wake vortex shedding process was found to be ‘delayed’, with the wake vortex structures beginning to shed much further downstream. As the Richardson number approached unity ( $\mathit{Ri}\geq 0. 72$ ), instead of having ‘Kármán’ vortices shedding alternately at the two sides of the heated cylinder, concurrent shedding of smaller vortex structures was observed in the near wake of the heated cylinder. The smaller vortex structures were found to behave more like ‘Kelvin–Helmholtz’ vortices than ‘Kármán’ vortices, and adjacent small vortices would merge to form larger vortex structures further downstream. It was also found that the shedding frequency of the wake vortex structures decreased with increasing Richardson number. The wake closure length and the drag coefficient of the heated cylinder were found initially to decrease slightly when the Richardson number was relatively small ( $\mathit{Ri}\lt 0. 31$ ), and then to increase monotonically with increasing Richardson number as the Richardson number became relatively large ( $\mathit{Ri}\gt 0. 31$ ). The average Nusselt number ( $ \overline{\mathit{Nu}} $ ) of the heated cylinder was found to decrease almost linearly with increasing Richardson number.
