Liquid Chromatography with a Fluorimetric Detection Method for Analysis of Paralytic Shellfish Toxins and Tetrodotoxin Based on a Porous Graphitic Carbon Column

Paralytic shellfish toxins (PST) traditionally have been analyzed by liquid chromatography with either pre- or post-column derivatization and always with a silica-based stationary phase. This technique resulted in different methods that need more than one run to analyze the toxins. Furthermore, tetrodotoxin (TTX) was recently found in bivalves of northward locations in Europe due to climate change, so it is important to analyze it along with PST because their signs of toxicity are similar in the bioassay. The methods described here detail a new approach to eliminate different runs, by using a new porous graphitic carbon stationary phase. Firstly we describe the separation of 13 PST that belong to different groups, taking into account the side-chains of substituents, in one single run of less than 30 min with good reproducibility. The method was assayed in four shellfish matrices: mussel (Mytillus galloprovincialis), clam (Pecten maximus), scallop (Ruditapes decussatus) and oyster (Ostrea edulis). The results for all of the parameters studied are provided, and the detection limits for the majority of toxins were improved with regard to previous liquid chromatography methods: the lowest values were those for decarbamoyl-gonyautoxin 2 (dcGTX2) and gonyautoxin 2 (GTX2) in mussel (0.0001 mg saxitoxin (STX)·diHCl kg−1 for each toxin), decarbamoyl-saxitoxin (dcSTX) in clam (0.0003 mg STX·diHCl kg−1), N-sulfocarbamoyl-gonyautoxins 2 and 3 (C1 and C2) in scallop (0.0001 mg STX·diHCl kg−1 for each toxin) and dcSTX (0.0003 mg STX·diHCl kg−1 ) in oyster; gonyautoxin 2 (GTX2) showed the highest limit of detection in oyster (0.0366 mg STX·diHCl kg−1). Secondly, we propose a modification of the method for the simultaneous analysis of PST and TTX, with some minor changes in the solvent gradient, although the detection limit for TTX does not allow its use nowadays for regulatory purposes.
Multiwarping for enhancing the frequency accuracy of digital waveguide mesh simulations

A multiwarping technique is introduced. The method is based on cascading frequency warping procedures and sample rate conversions. As a practical example, we show that with this new approach, the maximal frequency error of digital waveguide mesh simulations can be reduced by about 50%. This technique gives more degrees of freedom to attain a desired amount of nonlinear frequency shift still applying first-order allpass filters for processing finite-length digital impulse responses.

Structuring and Visualizing the Curricula with MIMA Search

Hideki Mima School of Engineering University of Tokyo Hongo 7-3-1, Bunkyo-ku, Tokyo 113-8656, Japan mima@t-adm.t. u-tokyo.ac. jp Abstract The main aim of the MIMA (Mining Information for Management and Acquisition) Search is to achieve “structuring knowledge” for accelerating knowledge exploitation in the domains of science and technology. The “structuring knowledge” that we define here indicates facilitating efficient knowledge acquisition and discovery of (new) knowledge contained in large textual collections by clarifying entire knowledge structures across domains. Currently, MIMA Search integrates modules: 1) knowledge storage, 2) (hierarchical) classification of knowledge, 3) analysis of knowledge, 4) visualization of knowledge. Several natural language processing techniques including information retrieval, automatic term recognition and term clustering are also exploited in the modules, aiming at integrating different types of knowledge sources (papers and patents, technologies and innovations) and knowledge domains, and simultaneously retrieving across different types of knowledge. We have applied MIMA Search to system for structuring and visualizing the curricula. Experiments using the syllabus data for the University of Tokyo’s Open Course Ware and school / department of engineering will also be mentioned.
Risk-sensitive plan execution for connected sustainable home

This paper presents a risk-sensitive model-based plan executive, p-Sulu, as well as its application to energy-efficient room temperature control of a smart residential building called Connected Sustainable Home. p-Sulu minimizes the use of heating and cooling by optimally controlling the incoming sunlight through a south-facing facade made of electrochromic glass windows, whose opacity can be changed. It also helps the residents to choose energy-efficient behaviors by making suggestions on their schedule, such as when to leave home and when to go to bed. Furthermore, in the presence of uncertainties in the solar radiation and the outdoor temperature, p-Sulu robustly operates within a user-specified upper bound on the probability of constraint violations. The resulting robust optimal scheduling and control problem is solved by iterative solution of mixed-integer linear programmings. We demonstrate by simulations that p-Sulu significantly reduces the energy consumption compared to existing control approaches, while successfully limiting the risk of failure to satisfy residents' requirements.
International Journal of Advanced Research in Computer Networking , Wireless and Mobile Communications

In this paper a technique is proposed to reduce the power consumption in clock distribution networks. Power has become a major issue in most VLSI designs. Power distribution in VLSI differs from product to product. However it is interesting to note that clock system and logic part itself consume most of total chip power. In practise a large portion of clock distribution network (CDN)s and flip flops. In this paper a reduced power flip flop design is used in CDNs. The simulations are done using Microwind and DSCH analysis software tools. Keywords— Flip-flop, full swing low swing, power, resonant clock
Optimal Data Mapping for Motion Compensation in H.264 Video Decoding

Long initial access cycles of SDRAM are the major performance burden of motion compensation in a video decoder. To minimize its effect while improve overall available memory bandwidth, this paper presents an optimal data mapping scheme for motion compensation in H.264 video coding. This scheme allocates the video data into suitable address and bank according to the access characteristics of SDRAM access and address transition in motion compensation. The resulted allocation can reduce the required bandwidth of motion compensation by 36% when compared to the previous design for 525SD video sequences.

A Low Power Consumption Implementation for WSN Nodes in Lumber Drying Kiln

Sensor network is receiving considerable attention as one of the key technologies to keep track of the parameters in the industrial field. Wireless sensor networks integrate sensor technology, embedded technology, and distributed information processing and network communication. The nodes of WSN serve the functions of perceiving and routing. Power consumption is the key factor affecting the longevity of nodes in practice. In this paper, we analyzed the power consumption of nodes in the network. Some methods are given in terms of hardware and software to reduce the sensor power consumption. A low power wireless sensor network nodes in the lumber drying kiln is designed and tested. Results show that this method is adaptive, feasible and prior to the other methods.
Pulmonary vascular wall stiffness: An important contributor to the increased right ventricular afterload with pulmonary hypertension

Pulmonary hypertension (PH) is associated with structural and mechanical changes in the pulmonary vascular bed that increase right ventricular (RV) afterload. These changes, characterized by narrowing and stiffening, occur in both proximal and distal pulmonary arteries (PAs). An important consequence of arterial narrowing is increased pulmonary vascular resistance (PVR). Arterial stiffening, which can occur in both the proximal and distal pulmonary arteries, is an important index of disease progression and is a significant contributor to increased RV afterload in PH. In particular, arterial narrowing and stiffening increase the RV afterload by increasing steady and oscillatory RV work, respectively. Here we review the current state of knowledge of the causes and consequences of pulmonary arterial stiffening in PH and its impact on RV function. We review direct and indirect techniques for measuring proximal and distal pulmonary arterial stiffness, measures of arterial stiffness including elastic modulus, incremental elastic modulus, stiffness coefficient β and others, the changes in cellular function and the extracellular matrix proteins that contribute to pulmonary arterial stiffening, the consequences of PA stiffening for RV function and the clinical implications of pulmonary vascular stiffening for PH progression. Future investigation of the relationship between PA stiffening and RV dysfunction may facilitate new therapies aimed at improving RV function and thus ultimately reducing mortality in PH.
Herpes Simplex Virus Latency-Associated Transcript Sequence Downstream of the Promoter Influences Type-Specific Reactivation and Viral Neurotropism

ABSTRACT Herpes simplex virus (HSV) establishes latency in sensory nerve ganglia during acute infection and may later periodically reactivate to cause recurrent disease. HSV type 1 (HSV-1) reactivates more efficiently than HSV-2 from trigeminal ganglia while HSV-2 reactivates more efficiently than HSV-1 from lumbosacral dorsal root ganglia (DRG) to cause recurrent orofacial and genital herpes, respectively. In a previous study, a chimeric HSV-2 that expressed the latency-associated transcript (LAT) from HSV-1 reactivated similarly to wild-type HSV-1, suggesting that the LAT influences the type-specific reactivation phenotype of HSV-2. To further define the LAT region essential for type-specific reactivation, we constructed additional chimeric HSV-2 viruses by replacing the HSV-2 LAT promoter (HSV2-LAT-P1) or 2.5 kb of the HSV-2 LAT sequence (HSV2-LAT-S1) with the corresponding regions from HSV-1. HSV2-LAT-S1 was impaired for reactivation in the guinea pig genital model, while its rescuant and HSV2-LAT-P1 reactivated with a wild-type HSV-2 phenotype. Moreover, recurrences of HSV-2-LAT-S1 were frequently fatal, in contrast to the relatively mild recurrences of the other viruses. During recurrences, HSV2-LAT-S1 DNA increased more in the sacral cord compared to its rescuant or HSV-2. Thus, the LAT sequence region, not the LAT promoter region, provides essential elements for type-specific reactivation of HSV-2 and also plays a role in viral neurotropism. HSV-1 DNA, as quantified by real-time PCR, was more abundant in the lumbar spinal cord, while HSV-2 DNA was more abundant in the sacral spinal cord, which may provide insights into the mechanism for type-specific reactivation and different patterns of central nervous system infection of HSV-1 and HSV-2.
Generative Workload Models of Internet Tra

With the World Wide Web (WWW) traac being the fastest growing portion of load on the internet, describing and characterizing this workload is a central issue for any performance evaluation study. In this paper, we present a Probabilistic Attributed Context Free Grammar (PACFG) 1] as a model for translating from a user oriented view of the workload (namely the conversations made within WWW browser windows) to the methods submitted to the Web servers (respectively to a proxy server). The characterization at this lower level is essential for estimating the traac on the net and are thus the starting point for evaluations of net traac.
Animal Pattern-Learning Experiments: Some Mathematical Background∗

A number of recent studies on the learning of invented patterns in symbol sequences by animals such as cottontop tamarins (Hauser, Chomsky & Fitch 2002:1578; Fitch & Hauser 2004; Hauser 2005; O’Donnell, Hauser & Fitch 2005), songbirds (Gentner 2005), and undergraduates (Fitch & Hauser 2004; Perruchet & Rey, in press) have shown interest in the contrast between two classes of sets of strings: the finite-state and the context-free. The claim of Fitch & Hauser (2004) is that tamarins can learn characteristic finitestate string patterns but not those that are context-free, while humans can learn both. Perruchet & Rey dispute the latter claim about humans; Gentner suggests that starlings show signs of being able to learn distinctively context-free patterns of recursion (self-embedding); and so on. Showing that a mechanism can learn some stringset in a certain class does not, of course, show that it can learn every stringset in that class (unless that stringset is complete for that class in the technical sense of computational complexity theory). But it is possible to provide evidence that the learnability boundary for some learning mechanism (the line between the stringsets it can and cannot learn) may fall between two hierarchically related stringset classes. One could do this by utilizing a pair of stringsets: one in the stronger (larger) class which cannot be learned (showing that not all stringsets in the stronger class are learnable) and one in the weaker (smaller) class which can be learned (showing that at least one stringset in the weaker class is learnable). But one would want to find a pair of stringsets that were relatively close to each other with respect to the hierarchy. One would not, for instance, choose a finite stringset and a strictly context-sensitive stringset if the aim was to find evidence that some mechanism could learn context-free but not context-sensitive stringsets.
Yik Yak: An Exploratory Study of College Student Uses and Gratifications

Publically launched in 2013 and discontinued in 2017, Yik Yak was an anonymous and geographically restricted social media application. A uses and gratifications theoretical framework and a mixed-methods research design were selected for this exploratory study regarding differences between Yik Yak users and nonusers. College students (n = 264) from a western university completed online surveys regarding Yik Yak in November of 2015. Results indicated that Yik Yak users were significantly younger than nonusers, and no significant differences were identified between Yik Yak users’ and nonusers’ reported time spent with other social media platforms (i.e., Facebook, Instagram, Twitter, and Snapchat). Qualitative results indicated that college students who used Yik Yak did so for informational, entertainment, agency-enhancement, and community-building purposes. Nonusers chose not to use Yik Yak because the application did not meet their needs, they were unaware of Yik Yak, and because of unfavorable content.
A systematic analysis of eight decades of incipient motion studies, with special reference to gravel‐bedded rivers

Data compiled from eight decades of incipient motion studies were used to calculate dimensionless critical shear stress values of the median grain size, . Calculated . values were stratified by initial motion definition, median grain size type (surface, subsurface, or laboratory mixture), relative roughness, and flow regime. A traditional Shields plot constructed from data that represent initial motion of the bed surface material reveals systematic methodological biases of incipient motion definition; . values determined from reference bed load transport rates and from visual observation of grain motion define subparallel Shields curves, with the latter generally underlying the former; values derived from competence functions define a separate but poorly developed field, while theoretical values predict a wide range of generally higher stresses that likely represent instantaneous, rather than time‐averaged, critical shear stresses. The available data indicate that for high critical boundary Reynolds numbers and low relative roughnesses typical of gravel‐bedded rivers, reference‐based and visually based studies have ranges of 0.052–0.086 and 0.030–0.073, respectively. The apparent lack of a universal for gravel‐bedded rivers warrants great care in choosing défendable values for particular applications.
Multicast Scaling Laws with Hierarchical Cooperation

A new class of scheduling policies for multicast traffic are proposed in this paper. By utilizing hierarchical cooperative MIMO transmission, our new policies can obtain an aggregate throughput of $\Omega\big((\frac{n}{k})^{1-\epsilon}\big)$ for any $\epsilon>0$. This achieves a gain of nearly $\sqrt{\frac{n}{k}}$ compared with non-cooperative scheme in \cite{paper:MulticastCapacityXYLi}. Between the two cooperative strategies in our paper, the converge-based one is superior to the other on delay, while the throughput and energy consumption performances are nearly the same. Moreover, to schedule the traffic in a converge multicast manner instead of the simple multicast, we can dramatically reduce the delay by a factor nearly $(\frac{n}{k})^\frac{h}{2}$, where $h>1$ is the number of the hierarchical layers. Our optimal cooperative strategy achieves an approximate delay-throughput tradeoff $D(n,k)/T(n,k)=\Theta(k)$ when $h\rightarrow\infty$. This tradeoff ratio is identical to that of non-cooperative scheme, while the throughput performance is greatly improved. Besides, for certain $k$ and $h$, the tradeoff ratio is even better than that of unicast.
A Revised Cepheid Distance to NGC 4258 and a Test of the Distance Scale

In a previous paper we reported a Hubble Space Telescope (HST) Cepheid distance to the galaxy NGC 4258 obtained using the calibrations and methods then standard for the Key Project. Here we reevaluate the Cepheid distance using the recently revised Key Project procedures. These revisions alter the zero points and slopes of the Cepheid period-luminosity (P-L) relations derived at the Large Magellanic Cloud (LMC), the calibration of the HST WFPC2 camera, and the treatment of metallicity differences. We also provide herein full information on the Cepheids described in the previous paper. Using the refined Key Project techniques and calibrations, we determine the distance modulus of NGC 4258 to be 29.47 ± 0.09 (unique to this determination) ±0.15 mag (systematic uncertainties in Key Project distances), corresponding to a metric distance of 7.8 ± 0.3 ± 0.5 Mpc and 1.2 σ from the maser distance of 7.2 ± 0.5 Mpc. Additionally, we place weak limits upon the distance to the LMC and upon the effect of metallicity in Cepheid distance determinations.
Metal Reduction and Iron Biomineralization by a Psychrotolerant Fe(III)-Reducing Bacterium, Shewanella sp. Strain PV-4

ABSTRACT A marine psychrotolerant, dissimilatory Fe(III)-reducing bacterium, Shewanella sp. strain PV-4, from the microbial mat at a hydrothermal vent of Loihi Seamount in the Pacific Ocean has been further characterized, with emphases on metal reduction and iron biomineralization. The strain is able to reduce metals such as Fe(III), Co(III), Cr(VI), Mn(IV), and U(VI) as electron acceptors while using lactate, formate, pyruvate, or hydrogen as an electron donor. Growth during iron reduction occurred over the pH range of 7.0 to 8.9, a sodium chloride range of 0.05 to 5%, and a temperature range of 0 to 37°C, with an optimum growth temperature of 18°C. Unlike mesophilic dissimilatory Fe(III)-reducing bacteria, which produce mostly superparamagnetic magnetite (<35 nm), this psychrotolerant bacterium produces well-formed single-domain magnetite (>35 nm) at temperatures from 18 to 37°C. The genome size of this strain is about 4.5 Mb. Strain PV-4 is sensitive to a variety of commonly used antibiotics except ampicillin and can acquire exogenous DNA (plasmid pCM157) through conjugation.
Self-Calibration of Camera-Equipped Robot Manipulators

A new approach to self-calibrate a camera-equipped robot manipulator is proposed in this paper. Self-calibration here means that the camera-robot system is capable of determining its geometric parameters without any external measurements and/or ground truth calibration data. With the proposed approach, one is able to identify all the rotational parameters and, up to a scale factor, all the translational parameters of a robotic system without any ground truth data. It is known from the computer vision literature that the extrinsic and intrinsic parameters of the camera can be obtained up to a scale factor by using the corresponding points of objects in a natural environment from an image sequence without knowing the positions of these object points. It is also well known that if the camera is treated as the tool of the robot, one is able to compute the corresponding robot pose directly from the camera-extrinsic parameters. An important question is how to determine the scale factors, which vary from one robot pose to another. It is discovered in this paper that if the robot pose measurement configurations follow a specially planned optimal trajectory, a unique scale factor can be used for all the poses measured along the trajectory. Thus, one is able to identify all the independent parameters of the robot with the poses measured in this manner with an inherently undetermined scale factor. One question remains: how do we obtain this unknown scale factor? Actually, the problem can be solved in a separate process. By two views of, say, a yardstick with the known length, the scale factor can be computed. If more than one measurement of the scale or measurements of multiple scales are provided from different viewing angles, the scale factor can be estimated with better accuracy in a least squares sense. Extensive simulation and experiment studies on a PUMA 560 robot reveal the convenience and effectiveness of the proposed approach.
The Transmission of Monetary Policy in a Multisector Economy

This article constructs and estimates a sticky-price, Dynamic Stochastic General Equilibrium model with heterogeneous production sectors. Firms in different sectors vary in their price rigidity, production technology, and the combination of material and investment inputs. In particular, firms buy inputs from all sectors using the actual Input–Output Matrix and Capital Flow Table of the U.S. economy. By relaxing the standard assumption of symmetry, this model allows idiosyncratic sectoral dynamics in response to monetary policy shocks. The model is estimated by the Generalized Method of Moments using sectoral and aggregate U.S. time series.
