BLUE: A New Class of Active Queue Management Algorithms (1999)

In order to stem the increasing packet loss rates caused by an exponential increase in network traffic, the IETF is considering the deployment of active queue management techniques such as RED [13]. While active queue management can potentially reduce packet loss rates in the Internet, this paper shows that current techniques are ineffective in preventing high loss rates. The inherent problem with these queue management algorithms is that they all use queue lengths as the indicator of the severity of congestion. In light of this observation, a fundamentally different active queue management algorithm called BLUE is proposed. BLUE uses packet loss and link idle events to manage congestion. Using simulation and controlled experiments, BLUE is shown to perform significantly better than RED both in terms of packet loss rates and buffer size requirements in the network. As an extension to BLUE, a novel technique for enforcing fairness among a large number of flows is described. In particular, this paper proposes and evaluates Stochastic Fair BLUE (SFB), a queue management algorithm which can identify and rate-limit non-responsive flows using a very small amount of state information.

Improving Resource Utilization of a Cloud-Based Testing Platform for Android Applications (2015)

The Cloud Testing Platform (CTP) is a cloud-based system for testing Android applications (apps). It can be used to test whether an Android app can provide consistent user experiences on diverse devices developed by different manufacturers with customized specifications and operating system versions. The CTP employs virtual machines (VMs) to interact with various mobile devices currently for performing tests. However, improper size of VM pool and unbalanced loads on devices can result in low resource utilization or increase the response time of tests. To manage the resources of CTP more effectively, this paper presents a resource adaptation strategy that can adjust the number of VMs dynamically based on the workload of CTP and the number of available devices and can balance the loads across multiple devices of the same type to improve their usages and the average waiting time of tests. Experimental results indicate that the proposed strategy can be promising on improving the resource utilization of CTP.
The polyhomeotic gene of Drosophila encodes a chromatin protein that shares polytene chromosome-binding sites with Polycomb. (1992)

The Polycomb group (PcG) genes in Drosophila melanogaster are required for maintenance of correct spatial expression of homeotic genes, and their products are thought to form either a regulatory network or act as a multimeric complex. Recently, it has been suggested that because of homology between Polycomb (Pc) and Su(var)205, PcG genes encode chromatin proteins required for the maintenance of a determined state in chromatin. The polyhomeotic (ph) gene is a member of the PcG of genes. We present DNA sequence of a ph cDNA, which encodes a 169-kD protein with a single putative zinc finger, a serine/threonine-rich region, and has glutamine repeats, suggesting that ph is a DNA-binding protein. Polyclonal antisera directed against ph protein bind to approximately 80 sites on polytene chromosomes. Most of these sites appear to be the same as those recognized by antibodies to Pc protein. ph protein binds to insertion sites of constructs containing DNA from the bithoraxoid (bxd) region of the Bithorax complex, showing that ph binding to chromatin is DNA dependent. The same bxd constructs are recognized by Pc protein, strongly supporting the hypothesis that ph and Pc interact directly.
Role of glutamate and GABA in the pathophysiology of epilepsy (1995)

Abstract Epilepsy, a paroxysmal disorder characterized by abnormal neuronal discharges, is common in children. While the causes of epilepsy are many, the fundamental disorder is secondary to abnormal synchronous discharges of a network of neurons. Whether or not a seizure occurs in a child depends upon the balance between excitability and inhibition. Central nervous system neurotransmitters have significant effects on neuronal excitability and play a pivotal role in brain excitability. The most common excitatory neurotransmitter in the brain, glutamate, has been implicated in both the initiation and propagation of seizures as well as brain damage that can occur following prolonged or repeated seizures. Gammaaminobutyric acid, the most common inhibitory neurotransmitter, usually suppresses seizure activity, although in absence seizure drugs that enhance GABA may exacerbate seizures. Experience with GABA indicates that certain neurotransmitters may have either anticonvulsant or proconvulsant effects depending on the neuronal networks involved. While other neurotransmitters also have effects on neuronal excitability, their function in epilepsy remains to be defined. © 1995 Wiley‐Liss, Inc.

Post-translational Disruption of the ΔF508 Cystic Fibrosis Transmembrane Conductance Regulator (CFTR)-Molecular Chaperone Complex with Geldanamycin Stabilizes ΔF508 CFTR in the Rabbit Reticulocyte Lysate (2000)

The DeltaF508 mutation of cystic fibrosis transmembrane conductance regulator (CFTR) is a trafficking mutant, which is retained and degraded in the endoplasmic reticulum by the ubiquitin-proteasome pathway. The mutant protein fails to reach a completely folded conformation that is no longer a substrate for ubiquitination ("stable B"). Wild type protein reaches this state with 25% efficiency. In this study the rabbit reticulocyte lysate with added microsomal membranes has been used to reproduce the post-translational events in the folding of wild type and DeltaF508 CFTR. In this system wild type CFTR does not reach the stable B form if the post-translational temperature is 37 degrees C, whereas at 30 degrees C the behavior of both wild type and mutant proteins mimics that observed in the cell. Geldanamycin stabilizes DeltaF508 CFTR with respect to ubiquitination only when added post-translationally. The interaction of wild type and mutant CFTR with the molecular chaperones heat shock cognate 70 (hsc70) and heat shock protein 90 (hsp90) has been assessed. Release of wild type protein from hsc70 coincides with the cessation of ubiquitination and formation of stable B. Geldanamycin immediately prevents the binding of hsp90 to DeltaF508 CFTR, and after a delay releases it from hsc70. Release of mutant protein from hsc70 also coincides with the formation of stable B DeltaF508 CFTR.
Differential activation pattern of redox-sensitive transcription factors and stress-inducible dilator systems heme oxygenase-1 and inducible nitric oxide synthase in hemorrhagic and endotoxic shock (2001)

These data suggest that AP-1 but not NF-kappaB activation is dependent on reactive oxygen intermediates in vivo and contributes to HO-1 gene expression. Thus, AP-1-dependent HO-1 induction under oxidative stress conditions may subserve a similar function as a stress-inducible vasodilator system as does NF-kappaB-dependent iNOS expression in liver inflammation.
Investigating Activity Patterns In Prehispanic Plazas: Weak Acid‐Extraction ICP–AES Analysis of Anthrosols at Classic Period El Coyote, Northwestern Honduras (2004)

Weak acid‐extraction ICP–AES analysis was performed to obtain multi‐elemental characterizations of anthropogenic sediments from plaza spaces that no longer contain artefacts and adjacent trash deposits at the prehispanic site of El Coyote in northwestern Honduras. Multivariate quantitative assessments of the anthrosol chemical data, along with associated inventories of midden materials, are examined to derive signatures for activity areas and refuse dumps that can be linked across portions of the site. The findings of this study permit the reconstruction of activity patterns in the site's main plaza and in its environs. This has important implications for understanding the relationship among ritual practice, craft production and political economy during the Late and Terminal Classic periods, c. ad 600–1000.
Quorum sensing inhibition activity of garlic extract and<i>p</i>-coumaric acid (2009)

Aims: The goal of this work was to investigate the influence of DMSO, garlic extract and p-coumaric acid on bacterial quorum sensing (QS). Methods and Results: The decreases in the QS responses of QS reporter strains Escherichia coli pSB401 and pSB536, Agrobacterium tumefaciens NTL4, Chromobacterium violaceum 5999 and wt 494, Pseudomonas putida IsoF/gfp and environmental Pseudomonas chlororaphis were quantified in relation to growth inhibitory effects. DMSO showed no significant QS-specific effects on the strains tested even at close-to-lethal concentrations. Garlic extracts antagonized the activity of QS receptors LuxR, AhyR and TraR, but were toxic at higher concentrations. P-coumaric acid fully inhibited QS responses of 5999, NTL4 and P. chlororaphis, with no influence on cell viability. Conclusions: The quorum sensing inhibition activity of garlic was extended to novel receptors, and p-coumaric acid was found to possess previously undescribed QS antagonist properties. Significance and Impact of the Study: The results suggest that p-coumaric acid might act as QS inhibitor. Further studies are required to understand its role in the regulation of QS and investigate structurally related compounds.
A low-power ASIC design for cell search in the W-CDMA system (2004)

This paper presents a low-power ASIC design for cell search in the wideband code-division multiple-access (W-CDMA) system. A low-complexity algorithm that is able to work satisfactorily under the effect of large frequency and clock errors is designed first. Then, a set of low-power measures are employed in the design of hardware architecture and circuits. Finally, through power analysis, critical blocks are identified and redesigned so as to further reduce the power consumption. The final design shows that the power is reduced by 51% from the original design of 133.6 mW to 65.49 mW, and its core area is also reduced by 31.9% from 3.4/spl times/3.4 mm/sup 2/ to 2.8/spl times/2.8 mm/sup 2/. The design is implemented and verified in a 3.3-V 0.35-/spl mu/m CMOS technology with clock rate 15.36 MHz.
Characterization of L5178Y cell phenotypes isolated during progression of the tumor-dormant state in DBA2 mice. (1984)

During the course of the L5178Y tumor-dormant state in DBA/2 mice, there is continual selection of a tumor cell subpopulation ("emergent" phenotype) from the uncloned original L5178Y population used to initiate the tumor-dormant state. In vivo and in vitro experiments show that the emergent-phenotype tumor cells are less capable than "original"-phenotype cells, which constitute the majority of the L5178Y cell inoculum, of restimulating cytolytic T-lymphocyte (CTL) activity in tumor-dormant mice and are less susceptible to lysis by those CTL. Both original- and emergent-phenotype tumor cells are capable of eliciting an immune CTL response in naive mice, but again emergent-phenotype cells are poorly lysed by this response. As a consequence of these characteristics, emergent-phenotype cells rapidly form ascitic tumors when used as a challenge in L5178Y cell-immunized mice and cannot establish a tumor-dormant state. Results presented here and in previous publications indicate that CTLs are the major host cells involved in the selection of emergent-phenotype L5178Y cells during the course of the tumor-dormant state. Heterogeneity of the tumor cell challenge inoculum is important in establishing the L5178Y tumor-dormant state. The state, once established, is maintained by an immune CTL response which is continuously being restimulated by the strongly immunogenic original-phenotype L5178Y cells. The tumor-dormant state terminates when the less immunogenic and more immunoresistant emergent-phenotype tumor cells predominate and escape the waning immune response.

Metal bacteriochlorophylls as PDT sensitizers have very good properties and this is a way to develop new PDT sensitizers.
Non-convergence of the L-curve regularization parameter selection method (1996)

The L-curve method was developed for the selection of regularization parameters in the solution of discrete systems obtained from ill-posed problems. An analysis of this method is given for selecting a parameter for Tikhonov regularization. This analysis, which is carried out in a semi-discrete, semi-stochastic setting, shows that the L-curve approach yields regularized solutions which fail to converge for a certain class of problems. A numerical example is also presented which indicates that this lack of convergence can arise in practical applications.
Detection of koi herpesvirus DNA in tissues of infected fish (2002)

A newly recognized herpesvirus, koi herpesvirus or KHV, causes a lethal disease in common carp, Cyprinus carpio , and its colourful strain known as koi or fancy carp. In this study, we report new outbreaks of the disease, present initial characterization of the KHV genome, and describe assays for detection of KHV DNA in infected cells and tissues of infected fish. Restriction endonuclease (RE) profiles of viral DNA derived from two epidemiologically distinct KHV isolates were identical to each other. Cloned KHV BamHI and SphI DNA probes specifically hybridized to KHV DNA, but not to DNAs derived from a variety of other fish herpesviruses. The KHV DNA probes detected KHV DNA in tissues of experimentally infected koi fish by DNA hybridization. The KHV specific polymerase chain assays (PCR) were developed for rapid detection and confirmation of KHV DNA in tissues of infected fish.
<scp>D</scp>‐aspartate modulates transcriptional activity in Harderian gland of frog, <i>Rana esculenta</i>: Morphological and molecular evidence (2005)

In the green frog, Rana esculenta, a substantial amount of D-aspartate (D-Asp) is found endogenously within the Harderian gland (HG) following its synthesis from L-aspartate (L-Asp) by an aspartate racemase. The frog HG is an orbital seromucoid gland that displays seasonal changes in secretory activity. Our in vivo experiments, consisting of i.p. injection of 2.0 mumol/g b.w. D-Asp in frogs collected during two periods of differing glandular activity (high or medium-low secretory activity), revealed that HG can to take up and accumulate D-Asp and that this amino acid may modulate the exocrine secretion through a kinase pathway. At a time when the gland shows relatively low secretory activity, i.p. administration of D-Asp rapidly induced activation of ERK1 and an increase in cells active in RNA synthesis. This increase in transcriptional activity was followed by a significant increase in mucous secretion. By contrast, administration of exogenous D-Asp when HG was showing high activity rapidly induced inhibition of both ERK1 and transcriptional activity. Since D-Asp is known to be recognized by receptors for N-methyl-D-aspartic acid (NMDA), it is possible that in the HG, D-Asp mediated NMDA activation may enhance the kinase pathway. The above activation of opposing stimulatory and inhibitory processes could reflect different levels of NMDA-receptor activity, which could vary as a function of the level of gland activity. This study provides the first evidence of a role for this excitatory amino acid in exocrine secretion. The effects of D-Asp in HG appear to be specific since they were not seen in frogs treated with other D- or L-amino acids with known excitatory effects on neurosecretion.
Investigation of Crystalline Iron-Platinum Nickel and Amorphous Rare Earth-Iron Alloys for Permanent Magnets. (1983)

Samarium-cobalt magnets have large-energy products but their cost is relatively high because of the use of expensive Sm and Co. A recent trend has been observed in industry to encourage conservation of cobalt and to find possible substitutes for this strategic material. The purpose of this program was to develop a permanent magnet without the use of cobalt which could be substituted for the AlNiCo commercial magnets. A number of magnetic materials were identified with properties that could be exploited in permanent magnet development. Contents: Experimental Techniques; Praseodymium-Iron-Gallium Alloys; Ternary Rare-Earth System; Praseodymium(Misch-Metal)-Terbium-Iron-Cobalt-Glass Former; Praseodymium-Iron(cobalt)-Glass Former; Iron-Platinum Based Alloys; Appendix: 'Characterization Studies of Rare Earth-Iron Magnetic Materials.
Comparison of the Evolutionary Strategies for the Surface Matching Based on Projective Area (2010)

This paper presents a research of applying some evolutionary strategies to obtain a 3-D surface from a 2-D patch in automotive styling. The patch is from an automotive sketch. In order to evaluate the efficiency of the surface matching based on the projective area overlapping, the simple strategy, the 1+1 evolutionary strategy, the μ+λ evolutionary strategy, and the improved simple strategy have been investigated to realise the optimal matching. The simulation results demonstrate that all the strategies applied here can tackle the surface matching problem. However, the improved simple strategy - the hybrid strategy - gives the better performances with the example of the windscreen parametric model for the evaluation.
The Genetic Basis of HIV-1 Resistance to Reverse Transcriptase and Protease Inhibitors. (2000)

HIV-1 drug resistance is caused by mutations in the reverse transcriptase (RT) and protease enzymes, the molecular targets of antiretroviral therapy. At the beginning of the year 2000, two expert panels recommended that HIV-1 RT and protease susceptibility testing be used to help select antiretroviral drugs for HIV-1-infected patients. Genotypic assays have been developed to detect HIV-1 mutations known to confer antiretroviral drug resistance. Genotypic assays using dideoxynucleoside sequencing provide extensive insight into the presence of drug-resistant variants in the population of viruses within an individual. However, the interpretation of these assays in clinical settings is formidable because of the large numbers of drug resistance mutations and because these mutations interact with one another and emerge in complex patterns. In addition, cross-resistance between antiretroviral drugs is greater than that anticipated from initial in vitro studies. This review summarises the published data linking HIV-1 RT and protease mutations to in vitro and clinical resistance to the currently available nucleoside RT inhibitors, non-nucleoside RT inhibitors, and protease inhibitors.

The ordering system uses the smart device to display the food picture on the menu by using augmented reality technology. The picking system let consumer use a smart device to take out food from dining cabinet by scan marker. It will reduce the mistake in ordering meal for foreigners, children or seniors who do not understand the country's language.
Load shedding, routing and frequency selection algorithms for high frequency hub networks (2002)

Described is a suite of integrated high frequency (HF) network management algorithms used in modelling a large Australian military HF tactical information network (HF Modernisation Project). The algorithms perform automatic node selection (routing), frequency selection and traffic load shedding in such a way as to maintain a high grade of service (GOS) for the highest priority traffic classes when a network is overloaded by offered traffic and when there are insufficient frequencies available to support traffic flows at times of poor ionospheric propagation and high spectral interference. We present simulation results which demonstrate the benefit and effectiveness of our algorithms in a large (205 node) hub network.
An Environment to Acknowledge the Interface between Affect and Cognition (1998)

Human intelligence is being increasingly redefined to include the all-encompassing effect of emotions upon what used to be considered ’pure reason’. With the recent progress of research in computer vision, speech/prosody recognition, and bio-feedback, real-time recognition of affect could very well prove to enhance humancomputer interaction considerably, as well as to assist further progress in the development of new emotion theories. We propose an adaptive system architecture designed to integrate the output of various multimodal subsystems. Based upon the perceived user’s state, the agent can adapt its interface by responding most appropriately to the current needs of its user, and provide intelligent multi-modal feedback to the user. We concentrate on one aspect of the implementation of such an environment: facial expression recognition. We give preliminary results about our approach which uses a neural network.
A zero-voltage and zero-current switching full bridge DC-DC converter with transformer isolation (2001)

A new primary-side-assisted zero-voltage and zero-current switching full bridge DC-DC converter with transformer isolation is proposed. The proposed DC-DC converter uses only one auxiliary transformer and two diodes to obtain ZCS for the leading leg. It has a simple and robust structure, and load current control capability even in short circuit conditions, The possibility of magnetic saturation due to asymmetricity of circuits or transient phenomena is greatly reduced, which is a very attractive feature in DC-DC converters with transformer isolation. The power rating of the auxiliary transformer is about 10% of that of the main transformer. Operation of a 12 kW prototype designed for welding application was verified by experiments.
Unsupervised Keypoint Learning for Guiding Class-Conditional Video Prediction (2019)

We propose a deep video prediction model conditioned on a single image and an action class. To generate future frames, we first detect keypoints of a moving object and predict future motion as a sequence of keypoints. The input image is then translated following the predicted keypoints sequence to compose future frames. Detecting the keypoints is central to our algorithm, and our method is trained to detect the keypoints of arbitrary objects in an unsupervised manner. Moreover, the detected keypoints of the original videos are used as pseudo-labels to learn the motion of objects. Experimental results show that our method is successfully applied to various datasets without the cost of labeling keypoints in videos. The detected keypoints are similar to human-annotated labels, and prediction results are more realistic compared to the previous methods.
Dynamics of the Entanglement between Two Oscillators in the Same Environment (2008)

We provide a complete characterization of the evolution of entanglement between two resonant oscillators coupled to a common environment. We identify three phases with different qualitative long time behavior. There is a phase where entanglement undergoes a sudden death. Another phase (sudden death and revival) is characterized by an infinite sequence of events of sudden death and revival of entanglement. In the third phase (no sudden death) there is no sudden death of entanglement, which persists for a long time. The phase diagram is described and analytic expressions for the boundary between phases are obtained. These results are applicable to a large variety of non-Markovian environments. The case of nonresonant oscillators is also numerically investigated.
