STUDENT TEACHERS SOCIALIZATION DEVELOPMENT BY TEACHING BLOG: REFLECTIONS AND SOCIALIZATION STRATEGIES

This study aims to probe into the cognitive sources and reflective content of student teachers’ socialization, such as job proficiency, goals and values, school culture, and role regulation by ‘teaching blog’. This paper utilizes eight student teachers of business, data processing, Chinese, English, science, and technology as subjects. Through Action Research, this study examines educational practices related to teaching practices, home teacher practices, administrative practices, and service learning from teaching blogs constructed by student teachers and online feedback. Moreover, this study collects qualitative data via in-depth interviews, tour visits, school meetings, teaching demonstrations, practice communications, and mail and analyzes the data with software by ATLAS.ti. Findings demonstrate as follows (1) student teachers’ teaching demonstration can enhance the socialization strategy of ‘job proficiency’; (2) teaching blog can present student teachers’ dialogues and feelings regarding ‘goals and values’ in the virtual community; (3) student teachers’ cognitive sources for socialization strategies of ‘school culture’ is based on peer student teachers, mentor teachers, and internet communities; and (4) socialization strategy of ‘role regulation’ is based on teacher certification and school expectations.
Review of Radiation Damage to Silicon Solar Cells

This paper reviews a large number of silicon solar cell irradiation experiments performed over the last 10 years, including 1-MeV and energy spectrum electron studies, and low-(100-keV) and high-energy (up to 155-MeV) proton studies on bare and covered silicon solar cells of several types. The results of satellite flight experiments on individual solar cells are also presented, as well as data from complete solar arrays and data on the new high-efficiency solar cells. Experimental evidence indicates that the percentage of degradation is smaller in thin solar cells than in thick ones, and that cells with high resistivity (10 ¿·cm) degrade less than cells with lower resistivity (1 ¿·cm). It is shown that high-efficiency silicon solar cells produced at COMSAT Laboratories and pilot production groups of these cells retain most of their increased power output under irradiation. It is emphasized that all surfaces and edges of the solar cells must be completely shielded from the large flux protons in the space environment. Insufficiencies in the published data are noted in certain areas, and recommendations for additional research are presented. Finally, an extensive bibliography is included.
Dynamic Traffic Grooming in Sliceable Bandwidth-Variable Transponder-Enabled Elastic Optical Networks

Traffic grooming has evolved to present some new features in sliceable bandwidth-variable transponder enabled elastic optical networks (SBVT-EON). One of the new features is “optical traffic grooming,” in which multiple optical flows from/to different sources/destinations can be groomed onto a sliceable transponder. When establishing a new connection request in SBVT-EON, a key problem is how to coordinate electrical and optical traffic grooming. In this study, we propose a three-layered auxiliary graph (AG) model to address mixed-electrical-optical grooming under dynamic traffic scenario. By adjusting the edge weights of AG, we can achieve various traffic-grooming policies for different purposes. Also, we propose two spectrum reservation schemes that can efficiently utilize the capacity of a transponder. We compare different traffic-grooming policies under two spectrum reservation schemes, and a tradeoff is shown to exist among the policies. We also evaluate their performances for different network topologies with different resource provisions.
A robust stability analysis approach for prediction of pilot in the loop oscillations

In this paper we deal with the analysis of Category II (nonlinear) Pilot in the Loop Oscillations (PIO). They are originated by a misadaptation between the pilot and the aircraft during some tasks in which tight closed loop control of the aircraft is required from the pilot, with the aircraft not responding to pilot commands as expected by the pilot himself. We propose a novel approach, based on robust stability analysis, which assumes that PIO are characterized by a limit cycle behaviour. In this approach the nonlinear elements are substituted by fictitious linear parameters, which can be considered time-invariant or time-varying. In the first case, by using ROBAN, a software tools based on polynomials methods developed by the authors, our approach is shown to recover the results of the Describing Function approach in the search for limit cycles. When the parameter is assumed to be time-varying, another method, based on the Quadratic Stability approach, gives a result which guarantees asymptotic stability (a stronger condition than the simple non existence of limit cycles) of the original nonlinear system. By the use of both methods a complete analysis of the nonlinear system can be performed. Finally, to demonstrate the use of the new proposed method in the prediction of Category II PIO, we apply our technique to a case study, namely the X-15 Landing Flare PIO [10].
Implementation of neural network for channel estimation in OFDM network

Channel estimation is an important field of interest in wireless OFDM networks. Lot of work has been done in this field, but only few techniques has presented good efficiency in channel estimation in OFDM network. This paper has presented the neural network based channel estimation for OFDM network using Raleigh channel. From result simulation, it has been concluded that obtained values of Mean Square Error (MSE) and Bit Error Rate (BER) are satisfactory using neural network in MATLAB environment.
When the Conversation Starts: An Empirical Analysis

We describe an exploratory study of what happens when a person en- ters a room where people are conversing, based on an analysis of 61 episodes drawn from the UTEP-ICT cross-cultural multiparty multimodal dialog corpus. We examine the reliability of coding of gaze and stance, and we develop a model for room-entry that accounts for observed differences in the behaviors of conversants, expressed as a state-transition model. Our model includes factors such as conversational task, not considered in existing social-force models, which appear to affect conversants' behaviors.
Harmonic-Suppressed Miniaturized-Element Frequency Selective Surfaces With Higher Order Bandpass Responses

We introduce a new technique for designing miniaturized-element frequency selective surfaces (MEFSSs) with bandpass responses and no spurious transmission windows over extremely large bandwidths. The proposed harmonic-suppressed MEFSSs consist of multiple metallic and dielectric layers. Each metallic layer is in the form of a two-dimensional arrangement of capacitive patches or an inductive wire grid with extremely sub-wavelength periods. Harmonic-free operation in these structures is achieved by using multiple, closely spaced capacitive layers with overlapping unit cells to synthesize a single, effective capacitive layer with a larger capacitance value. This allows for reducing the unit cell size of a conventional MEFSS considerably and moving the natural resonant frequencies of its constituting elements to considerably higher frequencies. Consequently, the spurious transmission windows of such MEFSSs, which are caused by these higher order harmonics, can be shifted to very high frequencies and an extremely broad frequency band free of any spurious transmission windows can be obtained. Using this technique, an MEFSS with a second-order bandpass response is designed to operate at 3.0 GHz with 20% fractional bandwidth and be free of spurious transmission bands up to 27.0 GHz. A prototype of this harmonic-free MEFSS is fabricated and experimentally characterized in the lab. Measurement results confirm harmonic-free operation of the proposed FSS for incidence angles in the ±60° range for both the TE and TM polarizations of incidence.
"Two out of three": an alternative method for codon reading.

An alternative method for codon reading, whereby only the first two codon nucleotides are recognized by the anticodon, is discussed and the experimental evidence for this "two of three" reading method is reviewed. Misreading of codons by the "two out of three" method could pose a significant threat to the fidelity of protein synthesis unless the genetic code is organized in such a way as to prevent this method from being used when it might compromise translational fidelity. Inspection of the genetic code shows that it is arranged in such a way that the "two out of three" reading method can be used without translational errors.
Scale-free network theory in studying the structure of the road network in Poland

This paper discusses the issue of statistical analysis of traffic flow in different regions of Poland. Such analysis allows us to identify “valuable (sensitive) areas” whose damage or blockage may provoke considerable disturbances or even a stoppage of traffic flow in the examined road network. The results of the studies indicate that the road network in Poland has the properties of a scale-free network. The distribution of the examined variables does not have a normal character, whereas the relationship between the number of nodes and the number of connections is a power-law feature.
The influence of feeding and aging on pork quality

The objective of the present thesis was to obtain a more basic understanding on how production factors such as feeding strategies and aging of the meat influence consumer-related pork quality attributes. Especially, post mortem colour characteristics of fresh pork and flavour development including warmed-over flavour in cooked pork as a function of feeding strategies have been further elucidated in the present thesis. It was found that diet-induced progress in early post mortem muscle temperature development affects the 3 colour and colour stability of pork during aging. Moreover, post-mortem colour development progressed differently in M. longissimus dorsi (LD) and in M. semimembranosus (SM). A gradual increase in the extent of blooming took place throughout aging in vacuum in the SM muscle; in contrast to a more complex colour progress during aging in the LD muscle. Moreover, discoloration was found to proceed faster in chops of SM compared to LD, especially after extended aging in vacuum. The observed diet and muscle effects might be coupled to the diet-induced change in post mortem temperature progress in the meat, which affects the activity of the inherent enzyme systems. Thus, dietary treatment and aging of the meat have a pronounced effect on colour and colour stability of pork. Moreover, it was found that diets with different sources of vegetable oil influence the fatty acid composition in pork without any pronounced effect on overall meat quality. However, positive correlations between specific fatty acids in the phospholipid fraction of LD and single sensory traits in pork from female pigs were established with polyunsaturated fatty acids and C18:2n-6 correlating to fried meat odour and sweet odour and with monounsaturated fatty acids and C18:1n-9 correlating to piggy flavour and sourish odour in freshly cooked pork. Finally, sensory attributes associated to warmed-over flavour and secondary lipid oxidation products formed during re-heating of cooked pork were positively correlated with gas-sensor responses (using electronic nose for detection of volatiles), and this supports the potential of e-nose systems as a quality control tool in the meat industry in the future.
Passivity-based control and Sliding Mode Control of hybrid DC power source applied to Hybrid Electric Vehicles

A Hybrid Electric Vehicle (HEV) is mainly composed of an Internal Combustion Engine (ICE) and an electrical machine. This electrical machine is connected to the DC power sources through an AC/DC inverter and DC/DC converters. Other than being used as a secondary source of the propulsion, this electrical machine together with the other electrical parts, may work as an “active flywheel” to compensate the torque ripples generated by ICE. These ripples are then “transferred” to the DC bus. A hybrid DC power source with battery as the main power and supercapacitor as the auxiliary power is explored in this paper. The DC part is modeled as a hybrid DC power source system with sinusoidal external current. Being different from other works where supercapacitors work as a rapid supplementary power during transient energy delivery or transient energy recovery, the supercapacitor studied here is used to absorb the consistent sinusoidal harmonic in the DC bus. Nonlinear control strategies are employed to achieve the objectives: Passivity-Based Control (PBC) is used to control the battery side bi-direction DC/DC converter to maintain the main power in the DC bus, and Sliding Mode Control (SMC) is applied to control the supercapacitor side bi-direction DC/DC converter to absorb the harmonic.
Vertical optical communication through stacked silicon wafers using hybrid monolithic thin film InGaAsP emitters and detectors

The authors report the first demonstration of vertical optical communication through stacked Si wafers using low-cost hybrid monolithic thin-film InGaAsP/InP emitters and detectors, designed for operation at 1.3 mu m. A thin-film InGaAsP homojunction light-emitting diode (LED) (4.5- mu m thick) was deposited onto a polished, nitride-coated Si wafer using a modified epitaxial liftoff technique. A InP/InGaAsP/InP p-i-n photodetector (4.5- mu m thick) was similarly deposited on an identically prepared Si wafer. The emitter and detector were then aligned, resulting in a stacked wafer configuration suitable for vertical through-wafer optical communication. This integration technique eliminates the need for direct growth of compound semiconductors onto Si. <<ETX>>
Biodiversity in the City: Fundamental Questions for Understanding the Ecology of Urban Green Spaces for Biodiversity Conservation

&NA; As urban areas expand, understanding how ecological processes function in cities has become increasingly important for conserving biodiversity. Urban green spaces are critical habitats to support biodiversity, but we still have a limited understanding of their ecology and how they function to conserve biodiversity at local and landscape scales across multiple taxa. Given this limited view, we discuss five key questions that need to be addressed to advance the ecology of urban green spaces for biodiversity conservation and restoration. Specifically, we discuss the need for research to understand how green space size, connectedness, and type influence the community, population, and life‐history dynamics of multiple taxa in cities. A research framework based in landscape and metapopulation ecology will allow for a greater understanding of the ecological function of green spaces and thus allow for planning and management of green spaces to conserve biodiversity and aid in restoration activities.
Visual Multiple Object Tracking with Improved Feature Detection and Kinect Color Depth Map

Tracking multiple objects in real-time videos represents a challenging area in the era of computer vision. This paper proposes a new method to track the multiple objects under different environment conditions such as rotation, illumination, blurred, occlusion, and many others. In addition, the kinect color depth image processing is used to estimate the distance of the objects. The tracking of multiple objects is formulated as classification task which competitively use the object features in the different video frames of the video sequences. To obtain the optimal configuration of feature classification, a neural network based framework is presented to make a global influence based on winner pixel estimation between the video frames. The objects are tracked efficiently in less time as compared with SIFT techniques and distance of objects is calculated with kinect based depth image processing. Experimental results are given for real-time scenes, and many experiments are conducted to examine the performance of the proposed approach. The proposed method resulted into efficient tracking of multiple objects in various conditions including rotation, scaling, occlusion, etc. The distance of multiple tracked objects is estimated using the kinect depth processing.
Inhibition of HDM 2 and Activation of p 53 by Ribosomal Protein L 23

The importance of coordinating cell growth with proliferation has been recognized for a long time. The molecular basis of this relationship, however, is poorly understood. Here we show that the ribosomal protein L23 interacts with HDM2. The interaction involves the central acidic domain of HDM2 and an N-terminal domain of L23. L23 and L11, another HDM2-interacting ribosomal protein, can simultaneously yet distinctly interact with HDM2 together to form a ternary complex. We show that, when overexpressed, L23 inhibits HDM2-induced p53 polyubiquitination and degradation and causes a p53-dependent cell cycle arrest. On the other hand, knocking down L23 causes nucleolar stress and triggers translocation of B23 from the nucleolus to the nucleoplasm, leading to stabilization and activation of p53. Our data suggest that cells may maintain a steady-state level of L23 during normal growth; alternating the levels of L23 in response to changing growth conditions could impinge on the HDM2-p53 pathway by interrupting the integrity of the nucleolus.
Angle variable holonomy in adiabatic excursion of an integrable Hamiltonian

If an integrable classical Hamiltonian H describing bound motion depends on parameters which are changed very slowly then the adiabatic theorem states that the action variables I of the motion are conserved. Here the fate of the angle variables is analysed. Because of the unavoidable arbitrariness in their definition, angle variables belonging to distinct initial and final Hamiltonians cannot generally be compared. However, they can be compared if the Hamiltonian is taken on a closed excursion in parameter space so that initial and final Hamiltonians are the same. The result shows that the angle variable change arising from such an excursion is not merely the time integral of the instantaneous frequency omega =dH/dI, but differs from it by a definite extra angle which depends only on the circuit in parameter space, not on the duration of the process. The 2-form which describes this angle variable holonomy is calculated.
Targeted interventions for difficult-to-treat asthma

Chronic persistent asthma has a significant burden in terms of healthcare-related expenses, decreased productivity and reduced quality of life for patients. Currently available guideline-directed therapy can control the majority of patients, but roughly one-third of patients will require additional care. This article reviews the barriers that hinder the ability of practitioners and patients to gain and maintain control of asthma, including inaccurate assessment measures, variability in patient response, and poor adherence. Strategies aimed at controlling difficult-to-treat disease, such as the use of biomarkers to assess control, are discussed. Newer and developing therapies that cater to specific types of asthmatic patients and may lead to improved outcomes in those patients for whom standard care is insufficient are also looked at.
Robustness analysis of nonlinear dynamic inversion control laws with application to flight control

This paper presents the development of robustness analysis tests for quasi-LPV models in the presence of time-varying, parametric uncertainty. The tests are applied for the robustness analysis of nonlinear dynamic inversion control laws giving sufficient conditions for assessing the nonlinear system's performance in the presence of bounded disturbances and uncertainty. The tests are formulated as linear minimisation problems subject to linear matrix inequality constraints and solved using a gridding procedure. An example is presented in which two nonlinear dynamic inversion control laws for the short-period dynamics of an aircraft are analysed.
Lessons from the Warwick and Chateau Chambord

As many managers continue to underperform the market and as active management becomes less effective, firms should consider the alternative of investment counseling, in which investment professionals attempt to add value by helping clients set objectives and policies. "New paradigm managers" would combine investment skill and multiproduct capability with the willingness to develop complex, long-term client relationships. Such organizations could reap great rewards by managing more funds for and thus earning more fees from each client.

Substantial heritable variation for susceptibility to Dothistroma septosporum within populations of native British Scots pine (Pinus

The threat from pests and pathogens to native and commercially planted forest trees is unprecedented and expected to increase under climate change. The degree to which forests respond to threats from pathogens depends on their adaptive capacity, which is determined largely by genetically controlled variation in susceptibility of the individual trees within them and the heritability and evolvability of this trait. The most signiﬁcant current threat to the economically and ecologically important species Scots pine ( Pinus sylvestris ) is dothistroma needle blight (DNB), caused by the foliar pathogen Dothistroma septosporum . A progeny-population trial of 4-year-old Scots pine trees, comprising six populations from native Caledonian pinewoods each with three to ﬁve families in seven blocks, was artiﬁcially inoculated using a single isolate of D. septosporum . Susceptibility to D. septosporum , assessed as the percentage of non-green needles, was measured regularly over a period of 61 days following inoculation, during which plants were maintained in conditions ideal for DNB development (warm; high humidity; high leaf wetness). There were signiﬁcant differences in susceptibility to D. septosporum among families indicating that variation in this trait is heritable, with high estimates of narrow-sense heritability (0.38 – 0.75) and evolvability (genetic coefﬁcient of variation, 23.47). It is concluded that native Scots pine populations contain sufﬁcient genetic diversity to evolve lower susceptibility to D. septosporum through natural selection in response to increased prevalence of this pathogen.
Ammonia sensing probe using shear horizontal surface acoustic wave technique

This study investigated an improved shear horizontal surface acoustic wave (SH-SAW) ammonia sensor based on L-glutamic acid hydrochloride. In order to satisfy Barkhausen criteria for oscillation and avoid mode hopping, it used coupling of modes (COM) theory to design a SH-SAW resonator. This SH-SAW sensor presented excellent reversibility, sensitivity, and repeatability when ammonia was in the ppb level. According to the signal-to-noise ratio of two, the estimated limit of detection (LOD) is 13.53 ppb.
