MOVEMENTS AND ACTIVITIES OF THE ATLANTIC BOTTLENOSE DOLPHIN, TURSIOPS TRUNCATUS, NEAR SARASOTA, FLORIDA

A tagging-observation program was conducted to study the behavioral ecology of Atlantic bottlenose dolphins near Sarasota, Florida. Forty-seven bottlenose dolphins (24 males, 23 females) werecaptured. tagged, and released a total of 90 times from 29 January 1975 through 25 July 1976. Tagged animals were identified during regular boat surveys, and information was collected on all individuals and groups encountered. A total of997 tagged or marked bottlenose dolphins were sighted. A population of bottlenose dolphins was identified in an estuarine-nearshore area extending about 40 km to the south from Tampa Bay and up to 3 km into the Gulfof Mexico. Social organization was characterized by small dynamic groups that appeared to be subunits ofa larger socially interacting herd. Average group size of 688 groups was 4.8 bottlenose dolphins (standard error = 0.16), Bottlenose dolphins concentrated in different areas seasonally, possibly in response to distribution changes of important prey species. Feeding strategies of the bottlenose dolphins apparently varied according to available water depth and differed from strategies of pelagic small cetaceans. Calving apparently occurred from spring to early fall.
Antijam capability analysis of RS-coded slow frequency-hopped systems

The application of Reed-Solomon codes in slow frequency-hopped systems has been extensively studied. Earlier investigations assumed an infinite interleaving length and considered partial-band noise jammers only. This paper extends previous efforts by analyzing the effect of finite interleaving length and the impact of band multitone jammers. We also explain why two-threshold (2T) erasure-insertion methods (EIM) are needed and examine their performance. Numerical results are presented to compare the effectiveness of the EIM and jammer types and to study the relationships among the hop rate, the interleaver size, and the code rate. The use of 2T-EIM necessitates the estimation of several additional channel and signal parameters. Simple and effective estimation algorithms are provided as well.
Self Organizing Neural Networks perform different from statistical k-means clustering

If Self Organizing Feature Maps (SOFMs) are enhanced by specially designed visualization algorithms like U-Matrix methods, they can be used for clustering. A common belief is, that the clustering abilities of this type of Artificial Neural Networks is identical or at least similar to the k-means algorithm used in statistics. In this paper we show by means of an nonlinear separable dataset, that the clustering abilities of SOFMs are quite different from the k-means algorithm. SOFMs were able to recognize clusters in a dataset where other statistical algorithms failed to produce meaningful clusters. The dataset used, called chainlink, may serve as a “benchmark” to compare clustering abilities of different algorithms.
A DOUBLY INEXACT INTERIOR PROXIMAL BUNDLE METHOD FOR CONVEX OPTIMIZATION

We propose a version of bundle method for minimizing a non-smooth convex function. Our bundle method have three features. In bundle method, we approximate the objective with some cutting planes and minimize the model with some stabilizing term. Firstly, it allows inexactness in this minimization. At the same time, evaluations of the objective and the subgradient are also required to generate the cutting planes. Secondly, inexact evaluation is also allowed. In this sense, our algorithm is doubly inexact. Thirdly, the stabilizing term are not assumed to be quadratic. We use interior proximal distance which was developed by Auslender and Teboulle, as the stabilizing term. We show that it globally converges to an optimal solution. Furthermore, it is also applicable to Lagrange relaxation problems. We show that both primal feasibility and optimality are asymptotically achieved.
E-CVFDT: An improving CVFDT method for concept drift data stream

Distribution of data stream is always changed in the real world. This problem is usually defined as concept drift [1]. The state-of-the-art decision tree classification method CVFDT[2] can solve the concept drift problem well, but the efficiency is debased because of its general method of handling instances in CVFDT without considering the types of concept drift. In this paper, an algorithm called Efficient CVFDT (E-CVFDT) is proposed to improve the efficiency of CVFDT. E-CVFDT introduces cache mechanism and treats the instances in three kinds of concept drift respectively, i.e. accidental concept drift, gradual concept drift, instantaneously concept drift. Besides, in E-CVFDT, the cached instances which have similar attributes will be sent in batches to calculate the information gain calculation rather than in sequence adopted by CVFDT. The experiments are carried out on the MOA platform. The results show that E-CVFDT algorithm achieves not only better efficiency but also higher accuracy than CVFDT algorithm.
Characterization and parameterization of dynamic wireless channels over long duration using evolutionary channel parameters

The characterization and parameterization of processes that arise in many fields of science and technology are very crucial. Of particular importance are dynamic processes whose statistics are time‐varying and are often modeled as stochastic processes. A typical example of such process is the wireless communication channel. Existing methods that are used to characterize and parameterize the dynamic stochastic wireless channel often consider short‐term duration over which the channel statistics are invariant. Conversely, this paper presents the characterization of the dynamic wireless communication channel over a long‐term duration where time/frequency channel realizations are obtained at sample intervals. To structure such channel realizations over a long duration, the idea of concatenating the ‘instantaneous’ channel realizations is presented. The resultant concatenated multivariable process is characterized using the concepts of process non‐summability and piecewise separability. Based on these concepts, the second‐order statistical parameterization of the concatenated stochastic process in both time and frequency domain is presented. The parameterization approach is based on fitting appropriate set of unit step functions that approximate the raw concatenated data using sets of evolutionary stationarity parameters. To illustrate the concepts developed in this paper, measurement‐based experiments and analysis are presented and adaptively applied to improve wideband multicarrier system performance.

1092-5171/02/2901-0068 ABSTRACT: Counseling older clients and their caregivers poses some unique challenges for speech-language pathologists and audiologists. This article provides basic guidelines for improving counseling exchanges with older adults. Clinicians are asked to consider the effects of physical and cognitive aging, social and economic influences, and clinician behaviors, experiences, and biases.
Research on Algorithm of Segment and Classification of audio in Broadcast

There are two common classes of audio, speech and music, in broadcast. An algorithm of segment and classification of audio designed in this paper will be applied to audio equalizer in the digital audio broadcasting transmitter. The algorithm described is based on zero crossing rate and energy that are able to separated non-silence segments from audio, and on Modified low energy ratio (MLER) and maximum likelihood criterion, which provides the ability to distinguish the two classes, speech and music. Modified low energy ratio is obtained on the basis of energy resulting in low computational complexity, leading to runs easily in real time. Experiment results to data show performance with the accuracy rate of over 96%.
A framed monochromatic x-ray microscope for ICF (invited)

The Laser Fusion Experiments Groups from the Laboratory for Laser Energetics (LLE) and the Los Alamos National Laboratory (LANL) have jointly developed an instrument capable of simultaneously space-, time-, and spectrally resolving x-ray emission from inertial confinement fusion (ICF) targets. Uses of the instrument include framed imaging of line emission from fuel or shell dopants and monochromatic backlighting. The x-ray imaging is accomplished with a Kirkpatrick-Baez (KB)-type four-image microscope, which has a best spatial resolution of ∼5 μm and a sensitive energy range of ∼2–8 keV. Time-resolved x-ray images are obtained with a pair of custom framing cameras, each of which records two of the four images in two independent 80-ps time intervals. In addition, the energy range of the images can be restricted to a narrow (monochromatic) spectral range (∼10–100 eV) by the introduction of diffracting crystals. This technique has been demonstrated with an e-beam-generated dc x-ray source, and at the LANL Tr.
Breaching of Triple-Brick Walls: Numerical Simulations

Explosive wall breaching will be a key war-fighter capability in future military operations by dismounted soldiers in urban terrain environments where the close proximity of urban structures, possibly occupied by noncombatants, significantly restricts the use of large demolition charges or large caliber direct-fire weapons. Because of this requirement, the US Army has focused considerable attention and resources to optimize breaching activities in urban terrain. As part of the Army's effort, the US Army engineer research and development center (ERDC) is conducting experimental and numerical investigations to improve wall breaching methods. The ongoing experimental and numerical programs will conduct comprehensive breaching research on a full range of urban construction materials. As a first step in this process, the ERDC conducted a successful baseline study of Composition C4 (C-4) breaching effectiveness against steel-reinforced-concrete walls. Recently, the research effort was extended to triple-brick walls. Numerical simulations of two selected experiments were conducted using the coupled Eulerian- Lagrangian code Zapotec. In these simulations, the brick and mortar were modeled as Lagrangian materials, and the C-4 was modeled as an Eulerian material.
Integrated approach to the in vivo genotoxic effects of a titanium dioxide nanomaterial using LacZ plasmid‐based transgenic mice

Titanium dioxide (TiO2) nanomaterials (NMs) are widely used in a diversity of products including cosmetics, pharmaceuticals, food, and inks, despite uncertainties surrounding the potential health risks that they pose to humans and the environment. Previous studies on the genotoxicity of TiO2 have reported discrepant or inconclusive findings in both in vitro and in vivo systems. This study explores the in vivo genotoxic potential of a well‐characterized uncoated TiO2 NM with an average diameter of 22 nm (NM‐102, from JRC repository) using several genotoxicity endpoints in the LacZ plasmid‐based transgenic mouse model. Mice were exposed by intravenous injection to two daily doses of NM‐102: 10 and 15 mg/kg of body weight/day. Micronuclei were analyzed in peripheral blood reticulocytes 42 hr after the last treatment. DNA strand breaks (comet assay) and gene mutations were determined in the spleens and livers of the same animals 28 days after the last treatment. Histopathological and cytological analyses were also performed in liver samples. Genotoxic effects were not detected in mice exposed to the nanosized TiO2 under the experimental conditions used, despite a moderate inflammatory response that was observed in the liver. Considering the biopersistence of TiO2 in mouse liver and the moderate inflammatory response, the possibility of a secondary genotoxic effect at higher doses and in conditions that result in a stronger inflammatory response, for example, within a longer time window, should be investigated further.

Local effects of various anions and H ions on dog limb and coronary vascular resistances.

The effect of intra-arterial infusion of an isosmotic solution of various sodium salts and acids on pressure gradients in the forelimb and heart was studied during constant rate blood perfusion. Forelimb resistance was reduced by Na pyruvate, Na acetate, Na nitrite, and Na citrate, by hydrochloric, nitric, lactic, pyruvic, acetic, and citric acids, and unchanged by NaCl, NaHCO3, NaNO3, and Na lactate. The molecular activity of Na acetate or Na nitrite exceeded that of Na pyruvate. All changes resulted mainly from fall of small vessel resistance. Na acetate also increased venous resistance, probably by a remote mechanism, and limb weight; the latter was more pronounced in the absence of artificial blood perfusion. Coronary resistance was decreased by Na acetate, Na nitrite, and Na citrate, increased slightly by NaHCO3, and unchanged by NaCl and Na lactate. Hence, the local effect of slight excess blood pyruvate, acetate, nitrite, citrate, or hydrogen is active arteriolar dilation, the activity of acetate or nitrite exceeds that of pyruvate, and acetate greatly increases tissue water storage.

ABSTRACT We describe a large outbreak involving a Klebsiella pneumoniae strain producing a plasmid-encoded ACC-1 type AmpC β-lactamase in a hospital caring for patients with motor impairment. The epidemic strain was isolated from 57 patients in six wards between September 1999 and May 2003 and caused clinical infections in 19 patients.
Transformer coupled novel noise cancellation technique for subthreshold UWB LNA

In this paper, a transformer coupled noise cancellation technique for subthreshold Ultra Wide Band (UWB) Low Noise Amplifier (LNA) is presented. This introduces a novel noise cancellation technique with current reuse topology and transformer coupling for better noise and gain performance. Moreover power consumption is considerably reduced by biasing both (two) stages in subthreshold region. This circuit is designed in UMC180nm process and simulated using SpectreRF simulator. This circuit achieved a maximum gain of 14dB and noise figure of 3.6dB over the 3dB bandwidth of 2.4-6GHz. This consumes 1.48mW of DC power from 1.5V supply. Hence the proposed circuit is very useful for WSN applications in ISM (2.4GHz) band and Ultra Wide Band (UWB) group I & II.

FACIL : Incremental Rule Learner for Classification of Data Streams

This paper describes an incremental classifier that provides a model formed by decision rules and border examples. Such examples are only linked with impure rules, so that they are instance–by–instance updated in order to describe decision boundaries. By means of this model, our approach can be seen as a multiple–window–based learning algorithm, using one window per impure rule. In addition, new examples can be classified by covering or distance such as the nearest neighbour algorithm. Furthermore, the algorithm can use an implicit forgetting heuristic so that positive and negative examples are removed from an impure rule when they are not the nearest neighbours one another.
Differential patterns of semaphorin expression in the developing rat brain

Semaphorins are a large family of cell‐surface and secreted proteins that have been shown to function as chemorepellents or inhibitors of growth cones of peripheral neurons, yet little is known about their role in patterning central pathways. In order to examine whether semaphorins may be involved in guiding the formation of the reciprocal thalamocortical connections in the rat, we have analysed the spatial and temporal expression of five recently identified rodent semaphorins (semB, C, D, F and G) using in situ hybridization. Transcripts of all five genes were present throughout the period examined (E15–P7) and displayed highly specific spatiotemporal distributions. We have based our discussion of putative semaphorin effects on their known functions as chemorepellents and found their spatiotemporal expression patterns compatible with such a role in several developmental events. Specifically, semaphorins are in the position to: (i) prevent neurite extension into the ventricular neuroepithelium throughout the brain; (ii) confer non‐permissive properties to the embryonic cortical plate, hence regulating the radial invasion of corticopetal afferents; (iii) confine axonal extension to the intermediate zone and subplate; (iv) maintain the fasciculated state of thalamocortical and corticothalamic axons, and prevent them from branching while they grow through the striatum; and (v) restrict the terminal arborizations of thalamic afferents to layer IV. The evidence that different semaphorin genes are often co‐expressed further suggests that the various molecules might interact in synergistic ways. Taken together, our results support the hypothesis that semaphorins could act as guidance signals in the development of the thalamocortical projections and suggest that innervation specificity is achieved through the combined action of multiple guidance cues. Furthermore, these data provide a basis for the design of functional assays and the study of mice carrying knockouts in specific semaphorin genes.
Comparison of the clinical and radiological outcomes of open reduction via medial and anterior approach in devleopmental dysplasia of the hip.

OBJECTIVES This study aims to investigate the effects of surgical approach on the clinical and radiological outcomes, the incidence of avascular necrosis (AVN), and the need for revision surgery in children undergoing open reduction via medial or anterior approach for developmental dysplasia of the hip (DDH). PATIENTS AND METHODS Forty-three hips of 36 patients (9 males, 27 females; mean age 13.8 month; range 6 to 18 months) treated for DDH, followed-up regularly for at least four years between January 1997 and December 2010, and who were aged five or above in the final control were included in this retrospective study. Patients were divided into two groups according to surgical approaches. Group 1 consisted of 21 hips of 19 patients who underwent open reduction through medial approach. Group 2 consisted of 22 hips of 17 patients who underwent open reduction through anterior approach. Groups were compared in terms of clinical and radiological outcomes as well as the incidence of AVN and the need for revision surgery. RESULTS There was no statistically significant difference between the groups with respect to clinical and radiological outcomes (p=0.407 and p=0.661, respectively). Similarly, there was no statistically significant difference between the groups in terms of AVN incidence and need for revision surgery (p=0.993 and p=0.170, respectively). On the other hand, acetabular index improved significantly in both groups at follow-up. CONCLUSION This study showed that open reduction via medial or anterior approach in DDH has similar clinical and radiological results, significant improvement was achieved in the acetabular index with both approaches, and no significant difference was present in the incidence of AVN and the need for revision surgery between the groups.
Cluster of DnaA Boxes Involved in Regulation of Streptomyces Chromosome Replication: from In Silico to In Vivo Studies

ABSTRACT In Streptomyces coelicolor, replication is initiated by the DnaA protein in the centrally located oriC region and proceeds bidirectionally until the replication forks reach the ends of the linear chromosome. We identified three clusters of DnaA boxes (H69, H24, and D78) which are in a relatively short segment of the chromosome centered on the oriC region. Of the clusters analyzed, D78 exhibited the highest affinity for the DnaA protein; the affinity of DnaA for the D78 cluster was about eightfold higher than the affinity for oriC. The high-affinity DnaA boxes appear to be involved in the control of chromosome replication. Deletion of D78 resulted in more frequent chromosome replication (an elevated ratio of origins to chromosome ends was observed) and activated aerial mycelium formation, leading to earlier colony maturation. In contrast, extra copies of D78 (delivered on a plasmid) caused slow colony growth, presumably because of a reduction in the frequency of initiation of chromosome replication. This suggests that the number of high-affinity DnaA boxes is relatively constant in hyphal compartments and that deletion of D78 therefore permits an increased copy number of either the chromosomal origin region or a plasmid harboring the D78 cluster. This system conceivably influences the timing of decisions to initiate aerial mycelial formation and sporulation.
The cosmic worm

Sometimes scientists would like to put their heads into interesting parts of their data sets and look around, but they are hampered by the "outside looking in" aspect of workstation-based visualization. At the Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago, we are attempting to break some of the visualization barriers with a distributed computing and visualization environment developed using the Cave Automatic Virtual Environment (CAVE) virtual reality theater. In particular, we are trying to provide physicists and astrophysicists at the National Center for Supercomputing Applications (NCSA) a new vehicle for scientific discovery. <<ETX>>
Redefining pT3 renal cell carcinoma in the modern era

The 2002 American Joint Committee on Cancer (AJCC) tumor classification for renal cell carcinoma (RCC) does not take into account concomitant venous invasion and extrarenal tumor extension (ERE). In the current study, the authors evaluated the prognostic significance of venous tumor thrombus (VTT) and its extent, the presence and location of ERE, and a combination of both features on survival after the surgical management of patients with pathologic T3 (pT3) RCC.
A novel honeycomb-like disk resonant gyroscope

This paper reports the design, fabrication and fundamental parameters testing of a novel honeycomb-like disk resonator gyroscope (HDRG). It has the same topological structure with the natural honeycomb and is composed of many interleaved hexagon cells, giving it the advantages of high space utilization ratio and excellent mechanical characteristics. Testing results show that it has about 17140Hz resonant frequency and the frequency split can be diminished to be <0.02Hz by electrostatic tuning. Q-factor and decay time constant under high level vacuum condition (0.004Pa) are about 81k and 1.507s respectively. The results demonstrate that this design is feasible and it has the ability to achieve high performance gyroscope standard.
