A method of counting the passing people by using the stereo images

The attempts to count the passing people by the image processing have been made some time ago. But the conventional methods could not count the passing people accurately unless there were very few of the passing people through the gate at one time. In this paper, we propose that passing people be accurately counted using images obtained by a stereo camera. In proposed method, the stereo camera is hung from the ceiling of the gate and the optical axis of the camera is set up so that the passing people could be observed from just overhead. In this system arrangement, if there are crowd people in the gate, then the data of the passing people are not overlapped each other on the obtained images. In addition, by using the stereo camera, the human region and road region on the obtained images are able to be segmented accurately, In this paper, we show some experimental results obtained by using a simple experimental system to verify effectiveness of the proposed method.
Solution to Linear Inverse Problem with MMV having Linearly Varying Sparsity Structure

In this paper, an extension to current algorithms dealing with inverse problem is considered. In stead of that invariant sparse profile of the solution vectors is concerned, we mainly focus on the problem with linearly varying sparse structures. Two methods are proposed to solve the linear inverse problem with the unknown linearly varying sparse structure by using MMV. In order to adapt to the linearly varying sparse profile of the solutions, one method, named LMMV (Linearly-MMV), introduces a new parameter and makes use of circular shift matrix to convert the new problem to the one with invariant sparse profile and new iterative algorithm is derived in principle of existing methods. Another method, named WMMV (Wide-MMV), attributes the change of the sparse structure of the solution vectors to the inaccuracy caused by the chosen dictionary and combines several rows of the dictionary together, which is equivalent to find a lower dimensional sparse solution and in turn gives a more robust algorithm. Numerical experiments with random dictionaries and applications to direction-of-arrival (DOA) estimation verify the validation of the proposed two methods and their superiority to some existing methods is illustrated.
An 1 GHz Class E LDMOS Power Amplifier

A class E power amplifier working at 1 GHz and with an LDMOS transistor as switching element has been developed. The circuit is implemented with lumped and distributed elements. An output power of 6.2 W at 69 % drain efficiency with a gain of 11 dB was obtained at 1 GHz. Both simulations and measurements of the amplifier are presented within this paper. This is to our knowledge the highest efficiency and output power reported for a class E amplifier at 1 GHz.
Lysine Decarboxylase Expression by Vibrio vulnificus Is Induced by SoxR in Response to Superoxide Stress

ABSTRACT Lysine decarboxylase expression by Vibrio vulnificus, which is up-regulated by CadC in response to acid stress, is also induced by SoxR in response to superoxide stress. SoxR binds to the promoter region of the cadBA operon, coding for a lysine-cadaverine antiporter (CadB) and a lysine decarboxylase (CadA). The induction of cadBA transcription by SoxR is independent of CadC. Cadaverine, which neutralizes the external medium, also appears to scavenge superoxide radicals, since increasing cellular cadaverine by elevating the gene dosage of cadBA significantly diminished the induction of Mn-containing superoxide dismutase under methyl viologen-induced oxidative stress. Consistently, a lack of cadaverine caused by mutation in cadA resulted in low tolerance to oxidative stress compared with that of the wild type.
Throughput and Fairness Improvement for WLANs with Long Propagation Delay Coexisting with Conventional WLANs

Long propagation delay in wireless local area networks (WLANs) such as long distance WLANs and WLANs with radio-over-fiber (RoF) technology increases frame collisions. In particular, when a conventional WLAN coexists with the WLAN with long delay, the propagation delay causes serious throughput degradation and unfairness between the uplink and the downlink in the WLAN with long delay. In this paper, we focus on WLANs with RoF technology (RoF WLANs), and to resolve these problems, we propose a method for improving system throughput and fairness between uplink and downlink transmissions. A numerical analysis based on the proposed model and a simulation evaluation show that the proposed method increases the total system throughput by 25% while achieving MAC-layer fairness between the uplink and downlink throughput for RoF WLANs, and increases the TCP throughput in RoF WLANs to the same level as conventional WLANs. Moreover, our proposed theoretical model for the coexistence of RoF and conventional WLANs agrees with the simulation results.
Gender, Depressive Symptoms and Patterns of Alcohol Use among College Students

Background: Serious alcohol-related negative consequences are associated with a number of drinking behaviors among college students. Thus, it is critical to identify students who are at greater risk for hazardous drinking. Although some studies have shown that depressive symptoms may be associated with alcohol use in this population, findings are not consistent. The current study extends previous research by investigating the relationship between depressive symptoms, daily alcohol use and compulsive drinking among college students and whether gender moderates these relationships. Sampling and Methods: The participants were 904 college students (495 females; mean age = 20.07 ± 1.85 years) who filled out questionnaires that focused on drinking behaviors and severity of depressive symptoms. Results: Gender moderated the relationship between depressive symptoms and daily alcohol consumption. In male college students, worse depressive symptoms were associated with increased daily alcohol use and with greater risk for compulsive drinking. In female college students, worse depressive symptoms increased the risk for compulsive drinking, but not for greater daily alcohol use. Conclusions: Results suggest that prevention programs aimed at decreasing harmful alcohol use among college students must take into consideration the role of both gender and depressive symptoms in the development of problematic drinking behaviors.
Efficient approximation to calculate time delay and dispersion in linearly chirped periodical microphotonic structures

The Bloch mode propagation through the chirped periodical structure is defined by its local dispersion relation. In a slowly varying structure its time delay is the integral of the local inverse group velocity along the propagation direction. The integration can be strongly simplified for linearly chirped structures if the assumption is made that the local dispersion relation is just a scaled and shifted version of the dispersion relation at the input. This assumption leads to exact solutions for the structures with locally uniaxial deformation and provides a good approximation for arbitrary structures with small chirps. The approach is demonstrated for high index contrast chirped Bragg mirrors and complicated photonic crystal waveguide structures, including coupled waveguides and a slow group velocity waveguide.
The validity of the Color Trail Test in the pre-driver assessment of individuals with acquired brain injury

Primary objective: To examine the validity of the Color Trails Test (CTT), a culture- fair analogue of the Trails Test, in the pre-driver assessment of individuals with acquired brain injury (ABI). Research design: Retrospective study. Methods and procedures: 30 participants with ABI completed the CTT and Useful Field of View (UFOV) in a driving rehabilitation clinic. Within the same week an on-road evaluation was conducted by a driving rehabilitation specialist, and a driving instructor. Results: 50% of the participants passed the on-road evaluation and 50% failed. Individuals who passed the on-road test performed the CTT1 and CTT2 faster than those who failed, however the difference between the pass/fail groups was significant only for the CTT1. A correlation analysis between the CTT subtests (CTT1 and CTT2) and the UFOV subtests revealed significant, moderate correlations between these measures. Conclusions: The CTT1 may contribute to the pre-driving screening by rapidly identifying those individuals who are most at risk for unsafe driving behaviors. Further studies are required with a larger representative sample.
A matching algorithm for catalytic residue site selection in computational enzyme design

A loop closure‐based sequential algorithm, PRODA_MATCH, was developed to match catalytic residues onto a scaffold for enzyme design in silico. The computational complexity of this algorithm is polynomial with respect to the number of active sites, the number of catalytic residues, and the maximal iteration number of cyclic coordinate descent steps. This matching algorithm is independent of a rotamer library that enables the catalytic residue to take any required conformation during the reaction coordinate. The catalytic geometric parameters defined between functional groups of transition state (TS) and the catalytic residues are continuously optimized to identify the accurate position of the TS. Pseudo‐spheres are introduced for surrounding residues, which make the algorithm take binding into account as early as during the matching process. Recapitulation of native catalytic residue sites was used as a benchmark to evaluate the novel algorithm. The calculation results for the test set show that the native catalytic residue sites were successfully identified and ranked within the top 10 designs for 7 of the 10 chemical reactions. This indicates that the matching algorithm has the potential to be used for designing industrial enzymes for desired reactions.
Applying observations of work activity in designing prototype data analysis tools

Designers, implementers, and marketers of data analysis tools typically have different perspectives than end users. Consequently, data analysts often find themselves using tools focused on graphics and programming concepts rather than concepts which reflect their own domain and the context of their work. Some user studies focus on usability tests late in development; others observe work activity, but fail to show how to apply that knowledge in design. This paper describes a methodology for applying observations of data analysis work activity in prototype tool design. The approach can be used both in designing improved data analysis tools, and customizing visualization environments to specific applications. We present an example of user-centered design for a prototype tool to cull large data sets. We revisit the typical graphical approach of animating a large data set from the point of view of an analyst who is culling data. Field evaluations using the prototype tool not only revealed valuable usability information, but initiated in-depth discussions about user's work, tools, technology, and requirements. <<ETX>>
Plasma Viremia and Cellular HIV-1 DNA Persist Despite Autologous Hematopoietic Stem Cell Transplantation for HIV-Related Lymphoma

Abstract: A cure of HIV-1 has been achieved in one individual through allogeneic stem cell transplantation with a CCR5[INCREMENT]32 homozygous donor. Whether myeloablation and autologous stem cell transplantation for lymphoma in patients on suppressive antiretroviral therapy can eliminate HIV-1 reservoirs is unknown. Low-level plasma viremia and total HIV-1 DNA and 2-LTR circles in blood mononuclear cells were quantified after autologous transplantation in 10 patients on suppressive antiretroviral therapy using quantitative polymerase chain reaction assays capable of single-copy nucleic acid detection. Plasma viremia was detectable in 9 patients, whereas HIV-1 DNA was detectable in all 10 patients, indicating that HIV-1 had not been eliminated.
Capacitance Expressions and Electrical Characterization of Tapered Through- Silicon Vias for 3-D ICs

Closed-form expressions of the parasitic insulator capacitance and the substrate capacitance for tapered through-silicon vias (T-TSVs) are proposed. The expressions are suitable for TSVs with high aspect ratio (thin and long). The maximum percentage errors between the calculated and simulated results for the insulator capacitance and the substrate capacitance are 1.86% and 3.75%, respectively. Then the equivalent circuit model of the T-TSV signal-ground pair is established and validated by comparison with the full-wave simulation results. Furthermore, the electrical characteristics of the T-TSV are evaluated with the proposed expressions. The results indicate that the T-TSV has longer latency and less crosstalk than the cylindrical TSVs.
A FCA-based Framework for Discovering Hidden Knowledge from Twitter Content

Web data mining is a hot research topic that is a technique used to crawl through various web resources to collect required information. As the importance of such web data mining has been recognized, extensive studies have been conducted actively to analyze the data in a Social Networking Service (SNS). In a SNS, a large amount of data, which has a variety of characteristics, is generated through voluntary participation of users, which is also called “big social data”. Big social data can identify not only content registered on the web but also the relations of the friends of users. In this paper, we introduce Formal Concept Analysis (FCA) as the basis for a practical and well founded methodological approach for web data analysis which identifies conceptual structures among data sets. As well as, we propose a framework for discovering hidden knowledge by using polarity from Twitter contents. Additionally, we show the experiments that demonstrate how our framework can be applied for knowledge discovery.
High-pressure granulites (retrograded eclogites) from the Hengshan Complex, North China Craton: petr

Both highand medium-pressure granulites have been found as because of the absence of modal minerals. The combination of petrographic textures, mineral compositions, metamorphic reaction enclaves and boudins in tonalitic–trondhjemitic–granodioritic gneisses in the Hengshan Complex. Petrological evidence from these history, petrogenetic grids and thermobarometric data defines a nearrocks indicates four distinct metamorphic assemblages. The early isothermal decompressional clockwise P–T path for the Hengshan prograde assemblage (M1) is preserved only in the high-pressure granulites, suggesting that the Hengshan Complex underwent initial granulites and represented by quartz and rutile inclusions within crustal thickening, subsequent exhumation, and cooling and retrothe cores of garnet porphyroblasts, and omphacite pseudomorphs gression. This tectonothermal path is considered to record a major that are indicated by clinopyroxene + sodic plagioclase symplectic phase of collision between two continental blocks, which resulted in intergrowths. The peak assemblage (M2) consists of clinopyroxene the final assembly of the North China Craton at >1·8 Ga. + garnet + sodic plagioclase + quartz ± hornblende in the high-pressure granulites and orthopyroxene + clinopyroxene + garnet + plagioclase + quartz in the medium-pressure granulites.
Public Key Threshold Multi-Message Signcryption (PK-TMMS) scheme with (t, n) shared verification

In this paper, Public Key Threshold Multi-Message Signcryption (PK-TMMS) scheme with (t, n) shared verification based on discrete logarithm problem is proposed. The (t, n) threshold is built based on the Shamir' secret sharing. The proposed scheme signcrypted multiple messages for each recipient using a multi-key generator. The multi-key generator played an important role for the communication overhead and computational cost saving in the PK-MM-MRS scheme. The proposed scheme has an efficient communication overhead and computational cost saving compared to Zheng multi-recipient signcryption scheme. The saving in communication overhead using the proposed scheme are 38.24 % for two messages, two recipients and 67.97 % for three messages, three recipients over Zheng multi-recipient signcryption scheme at the same parameters. The proposed scheme costs 50 % and 75 % less in computation cost for two and four signcrypted messages than does Zheng signcryption scheme. The saving in communication overhead and computational cost is increased as the number of messages and recipients increases.
Application traffic classification using payload size sequence signature

Recently, network traffic has become more complex and diverse because of the emergence of new applications and services. Therefore, the importance of application‐level traffic classification is increasing rapidly, and it has become a very popular research area. Although a lot of methods for traffic classification have been introduced in literature, they have some limitations to achieve an acceptable level of performance in real‐time application‐level traffic classification. In this paper, we propose a novel application‐level traffic classification method using payload size sequence signature. The proposed method generates unique payload size sequence signatures for each application using packet order, direction, and payload size of the first N packets in a flow and uses them to identify application traffic. The evaluation shows that this method can classify application traffic easily and quickly with high accuracy and completeness rates, over 99.93% and 93.45%, respectively. Furthermore, the method can classify each application traffic into its respective individual application. The evaluation shows that the method can classify all applications traffic, known and unknown (new) applications into their respective applications, and it can classify applications traffic that use the same application protocol or are encrypted into each other.
Quasar Feedback in the Ultraluminous Infrared Galaxy F11119+3257: Connecting the Accretion Disk Wind with the Large-scale Molecular Outflow

In Tombesi et al., we reported the first direct evidence for a quasar accretion disk wind driving a massive (>100 M⊙ yr−1) molecular outflow. The target was F11119+3257, an ultraluminous infrared galaxy (ULIRG) with unambiguous type 1 quasar optical broad emission lines. The energetics of the accretion disk wind and molecular outflow were found to be consistent with the predictions of quasar feedback models where the molecular outflow is driven by a hot energy-conserving bubble inflated by the inner quasar accretion disk wind. However, this conclusion was uncertain because the mass outflow rate, momentum flux, and mechanical power of the outflowing molecular gas were estimated from the optically thick OH 119 μm transition profile observed with Herschel. Here, we independently confirm the presence of the molecular outflow in F11119+3257, based on the detection of ∼±1000 km s−1 blue- and redshifted wings in the CO(1−0) emission line profile derived from deep ALMA observations obtained in the compact array configuration (∼2.″8 resolution). The broad CO(1−0) line emission appears to be spatially extended on a scale of at least ∼7 kpc from the center. Mass outflow rate, momentum flux, and mechanical power of (80–200) M⊙ yr−1, (1.5–3.0) LAGN/c, and (0.15–0.40)% , respectively, are inferred from these data, assuming a CO-to-H2 conversion factor appropriate for a ULIRG (R7 is the radius of the outflow normalized to 7 kpc, and LAGN is the AGN luminosity). These rates are time-averaged over a flow timescale of 7 × 106 yr. They are similar to the OH-based rates time-averaged over a flow timescale of 4 × 105 yr, but about a factor of 4 smaller than the local (“instantaneous”; ≲105 yr) OH-based estimates cited in Tombesi et al. The implications of these new results are discussed in the context of time-variable quasar-mode feedback and galaxy evolution. The need for an energy-conserving bubble to explain the molecular outflow is also reexamined.
A novel technique of retrograde nasal intubation for the Pierre Robin Sequence infant with a known difficult airway

and ⁄ or a large tongue, several maneuvers, including introduction of the ETT into the mouth prior to the insertion of the GVL, insertion of the ETT parallel and as proximal as possible to the blade, or insertion of the GVL nearer to the left corner of the mouth, may be attempted (3). When the distal end of the styletted ETT passes through the glottis, the ETT is rotated toward the right to reduce its anterior angulation and to facilitate alignment of the ETT with the axis of the trachea. Then the stylet is withdrawn, which helps to advance the ETT through the glottis into the trachea. To facilitate insertion of the ETT into the trachea, moreover, a slight rotation of the ETT is required after removing the stylet in some cases. If the difficulty to advance the ETT into the trachea still exists after above measures have been taken, the operator should reduce the upward lifting force of the GVL so that the patient’s head will be returned to the neutral position, and the ETT tip can be away from the anterior tracheal wall. Also, the patient’s head is slowly lifted (flexed). It makes long axis of the ETT to be more parallel to that of trachea. When a bougie is used to assist the intubation with a GVL, the operators must know that because of its elastic properties the conventional bougie (especially for pediatric version) tends to resume its linear form shortly after it has been configured to the patient requirements. In contrast, the modified Eschmann bougie can solve this problem satisfactorily because it includes a 1-mm steel wire core that provides the device with a memory feature (7), making it retain its desired shape during manipulation in the oropharynx. Once the modified Eschmann bougie is inserted the glottis, the ETT slides over it during visualization with the GVL. After the ETT enters the trachea, the modified Eschmann bougie is removed. During removal, it slides back within the walls of the ETT and resumes its initial shape, behaving like a conventional bougie that facilitates smooth extraction. Using these measures, we have not had any instances where the ETT could not be advanced into the trachea once the glottis is visualized in the pediatric patients undergoing the orotracheal intubation using a GVL.
