HIGH-DIMENSIONAL EXPLORATORY ITEM FACTOR ANALYSIS BY A METROPOLIS–HASTINGS ROBBINS–MONRO ALGORITHM

A Metropolis–Hastings Robbins–Monro (MH-RM) algorithm for high-dimensional maximum marginal likelihood exploratory item factor analysis is proposed. The sequence of estimates from the MH-RM algorithm converges with probability one to the maximum likelihood solution. Details on the computer implementation of this algorithm are provided. The accuracy of the proposed algorithm is demonstrated with simulations. As an illustration, the proposed algorithm is applied to explore the factor structure underlying a new quality of life scale for children. It is shown that when the dimensionality is high, MH-RM has advantages over existing methods such as numerical quadrature based EM algorithm. Extensions of the algorithm to other modeling frameworks are discussed.
Picosecond synchronously pumped optical parametric oscillator based on chirped quasi-phase matching

We investigate and model a picosecond synchronously pumped optical parametric oscillator (OPO) based on an aperiodically poled lithium niobate (APPLN) nonlinear crystal with a chirped quasi-phase-matching (QPM) grating. We observe remarkable spectral features with an asymmetric OPO spectrum consisting of a main peak with lower side-lobes. Depending on the sign of the QPM chirp rate, the side-lobes are located either on the red or on the blue side of the main peak. Meanwhile, side-bands develop in the depleted pump spectrum. We attribute these features to cascaded sum-/difference-frequency generation processes which are quasi-phase matched at different positions in the APPLN crystal. A terahertz-generation cascading effect is also observed and characterized at high pump power.

This sign plays very important role in a diagnosis of complicated appendicitis like obstructive appendicitis.
Review of Economics

Standard economic theory assumes individual preferences to be fixed and exogenously given. This view has been challenged by numerous empirical observations. In reaction to those challenges, economic theory has been modified, mostly by including additional arguments into individuals’ utility functions. Among the approaches that tackle preference change are new consumer theory, habit formation, interdependent and status preferences, social and emotional influences, and reference point-dependent preferences. Hence, while standard economics largely abide by their assumption of stable preferences, an array of alternative approaches is now available to account for changing tastes. Some of these approaches are old and have been discussed in the literature for many decades while others are younger. However, all approaches have in common that they, in some cases surprisingly, have not made it to standard microeconomics textbooks. This survey aims at putting the approaches in perspective. For each of them, empirical evidence as well as methodological issues are discussed.
Optimal Control Approach for Active Local Driving Assistance in Mobility Aids

This paper presents a system capable of providing active short-term driving assistance of robot wheelchair (Fig. 1). Combining the intelligence of active assistance with the freedom of location independence, A local intention estimator is proposed to predict the user’s intention according to sensor data without map information. An optimal control method with smooth policy update is then applied to generate more intuitive and safer trajectories by smoothly combining the predicted user intention, current sensor data and expert training data from a human demonstrator.

A Simple Reconfiguration of Sensor to Sensor Less Control in BLDC Motor - Based EVs

This project deals with a reconfiguration strategy for sensor fault-tolerant control (FTC) in brushless DC motor based electric vehicle. The proposed active FTC system is based on two control techniques: Hall effect sensor in the case of healthy sensors and sensor less control method based on current feedback in the case of failed hall sensors. The main objective behind the reconfiguration from one control to another sensor-less control is to achieve a short and smooth transition when switching from a controller to another sensor less controller in the case of a sensor failure. The scheme describes the modeling of brushless DC motor drive based on sensored and sensor-less control methods. For sensored control, commutation logic is obtained from rotor position detection using hall effect sensor feedback. for sensor less control, it is obtained from current feed-back form the BLDC motor. The motor operations are modelled in MATLAB/SIMULINK the entire drive is simulated.
Promotion- and Prevention-Focused Job Crafting: A Theoretical Extension and Meta- Analytical Test

We refine and extend the job demands-resources job crafting model with reasoning from regulatory focus theory to account for theoretical and empirical inconsistencies in relationships between the crafting of challenging and hindering job demands with employee motivation, health, and work outcomes. We tested our refined and extended job demands-resources job crafting model using meta- analytic structural equation modeling. First, we differentiated promotion-focused job crafting (i.e., job crafting through increasing job resources and challenging job demands) from prevention-focused job crafting (i.e., job crafting through decreasing hindering job demands). Second, we showed that promotion-focused job crafting consistently facilitates employee motivation, health, and work outcomes, whereas prevention-focused job crafting hampers employee motivation, health, and work outcomes. Implications for future research and practices are discussed.
Impact of Service Quality on Customer Satisfaction (Cs) in the Online Service

Service quality is an important issue in service management and is a function of the differences between expectation and performance along an established set of quality dimensions. Considerable research has focused on the nature of service quality, and there is general acceptance that service quality is composed of a number of underlying dimensions. However, there is a lack of agreement on the exact nature of these dimensions. Five main dimensions of service quality include tangibles, reliability, responsibility, assurance and empathy. This study generally aims to examine the impact of Companies Commission of Malaysia (SSM) service quality on customer satisfaction (CS) in the online service. Specifically, the objectives of this study are (i) examining the relationship between the dimensions of SSM service quality and the level of satisfaction for counter service and (ii)exploring the level of satisfaction for SSM counter service. To achieve the purpose of the study, a validated questionnaire was administered in six areas of Malaysia namely Head Quarter, Kuala Lumpur, Putra Jaya, Selangor, Sunway Putra Mall, and UTC KL. The design of this research was a survey study and, in total, 525 questionnaires were collected. The collected questionnaires were analyzed using Statistical SPSS Software Version 18.0. Both descriptive statistics (frequencies and percentages) and inferential statistics (correlation and multiple regression analysis) were used for analyzing the data. The results showed that the majority of the respondents agreed with the SSM‟s counter services. Moreover, there was a strong, positive correlation between all the dimensions of SSM service quality in the areas of study.
An objective measurement of TMTF by using envelope of cABR

The temporal modulation transfer function (TMTF) has been proposed as a means for estimating temporal resolution. There are several problems that need to be overcome in the measurement of TMTF. For example, the threshold may be misjudged due to a lack of concentration by the measurement person as many judgment efforts are required, and the measurement task may be misunderstood due to limited language recognition ability. An appropriate objective measurement method is needed to avoid interference in the measurement process. We focused on cABR (auditory brainstem response to complex sounds) for objective measurement of TMTF because cABR faithfully represents several temporal acoustical features, including the envelope component of complex sound stimuli. The results for the temporal characteristic of cABR using SAM noise as complex sound stimuli can be used as an objective measurement of TMTF because the degree of cABR fluctuation was found to be related to the modulation depth of the stimuli and might be related to the modulation detection thresholds derived from TMTF.
1 Advances and Perspectives of Light-gated 2 Phosphodiesterases for Optogenetic Applications 3

Second messengers, cyclic adenosine 3'-5'-monophosphate (cAMP) and cyclic guanosine 9 3'-5'-monophosphate (cGMP) are playing important roles in many animal cells by regulating 10 intracellular signaling pathways and modulating cell physiology. Environmental cues like 11 temperature, light and chemical compounds can stimulate cell surface receptors and trigger the 12 generation of second messengers and the following regulations. Spread of cAMP and cGMP is 13 further shaped by cyclic nucleotide phosphodiesterases (PDEs) for orchestration of intracellular 14 microdomain signaling. However, localized intracellular cAMP and cGMP signaling requires 15 further investigation. Optogenetic manipulation of cAMP and cGMP offers new opportunities of 16 spatio-temporally precise study of their signaling mechanism. Light-gated nucleotide cyclases are 17 well developed and applied for cAMP/cGMP manipulation. Recently discovered rhodopsin 18 phosphodiesterase gene from protists established new and direct biological connection between 19 light and PDEs. Light-regulated PDEs are under development and of demand to complete the 20 toolkit of cAMP/cGMP manipulation. In this review, we summarize the state of the art, pros and 21 cons of artificial and natural light-regulated PDEs and discuss potential new strategies of 22 developing light-gated PDEs for optogenetic manipulation. 23
Area Minimization of the DTB Multiplexer A Chip Component with High Wire Density and Congestion

The DTB Multiplexer is a component within an NXP chip called the BAP3. DTB Multiplexer provides a testing functionality for the chip. This component is purely combinational, and requires no clock, however this makes the component wiring-costly. This high wiring requirement leads to the area constraint imposed by the wiring demand rather than cell area, and this also leads to the DTB multiplexer reducing the placement area available for other modules. With this method, the wiring area is going to be estimated as the amount of congestion, which would cause detour in the design which results in extra wiring. Here, the DTB multiplexer is placed by external method instead of using the place and route tools usually used by the design team. Instead, the placement is done on MATLAB which is later ported to the place and route tools using script. The placement algorithm implemented in MATLAB is primarily based on two algorithm, Dplace for initial preplacement, which in turn utilizes diffusion preplacement algorithm, and modified C-ECOP for the congestion reduction. More detailed congestion estimation done by using an additional routing estimation algorithm which is based on One-Steiner routing algorithm. The result indicates that the modified C-ECOP can be used to reduce congestion, thus wiring area when paired with a good initial placement algorithm, but the initial placement algorithm and detailed congestion estimation algorithm with One-Steiner could be further improved, and further work is needed to integrate the result with commercial place and route tools.

Launch Acceptable Region Calculation Procedure using R- Project and MARS Algorithm

In this work, Launch Acceptable Region (LAR) for smart munitions will be defined and an approach with Multivariate Adaptive Regression Splines (MARS) will be given[4]. LAR can be defined as a region where the target will be successfully reached if the weapon is released within this zone. There is a flexibility of choosing different release points within a zone for guided munitions by reshaping their trajectories during flight, but this is not the case for the unguided weapons because of their ballistic trajectories. Similar to the balistic algorithms that computes release points for unguided weapons, Launch Acceptable Reagion algorithm are being developed for guided weapons. Using the non parametric regression methods is one of the approachs for calculation of LAR using the data sets obtained from simulation results. In this work, the methodologies developed for calculation of LAR using R-Project will be presented. In General, there are two types of LARs. First one is the In Zone LAR in which the munition reaches the target by following the predefined waypoints and successfully performs the desired impact angle and attack azimuth. In Range LAR represents the zone in which the munition directly goes to target without following the waypoints and does not take account of the desired impact conditions (See Figure 1). [1] [2], [3].
Multilayered Miniaturized Hairpin Resonator for Bandpass Filter Design

This paper present a multilayered bandpass fllter (BPF) operating at 2GHz. Four miniaturized hairpin resonators are positioned in pairs, laid on two difierent conductor layers to obtain the BPF response. The multilayer conflguration allows more ∞exibility in controlling the variation on the coupling efiect of the resonators, namely the horizontal coupling efiect between resonators on the same layer and vertical coupling efiect between the top and bottom overlaid resonators. The overall dimensions of the prototyped BPF are 65mm by 26mm. It is fabricated on two FR4 substrates with relative permittivity, "r = 4:7. Validation of the BPF design is obtained via good agreement between the simulated and measured results.
Core–Shell Gold/Silver Nanoparticles for Localized Surface Plasmon Resonance-Based Naked-Eye Toxin Biosensing

: The Localized Surface Plasmon Resonance (LSPR) phenomenon provides a versatile property for biodetection. Herein, this unique feature was employed to build up a homogeneous optical biosensor to detect staphylococcal enterotoxin A (SEA) in solution down to very low levels by naked-eye readout. If the initial position of the LSPR band is located in the cyan region, even a small red shift (~2-3 nm) induced by Refractive index (RI) change close to the surface of nanoparticles (NPs), could make the light absorption transit from cyan to green and become visually detectable via a concomitant change in the complementary colors. In this work, we aimed at synthesizing two types of NPs based on compositionally complex core-shell NPs - Ag shell on AuNPs (Au@AgNPs) and Ag inside gold nanoshell (Ag@AuNPs). By controlling the thickness of the shells as well as their surface chemistry with anti-SEA antibody, the LSPR band was tuned to near 495 and 520 nm, for Ag@AuNPs and Au@AgNPs, respectively. The two particle systems were subsequently applied as transducers to spectroscopically and visually detect anti-SEA antibody - SEA interactions. Upon addition of SEA large red-shifts of the LSPR band were observed spectroscopically and the limits of detection (LOD) were estimated to 0.2 nM and 0.4 nM for the Au@AgNPs and Ag@AuNPs, respectively. Although the two sets of NPs gave almost identical LOD, the Ag@AuNPs whose initial position of the LSPR band was tuned in the cyan to green region (~500 nm) displayed a substantially more distinct color change from orange to red, as revealed by the by naked-eye. We foresee significant potential to this strategy in medical diagnostic and environmental monitoring, especially when basic laboratory infrastructure is sparse or non-existent.

Generating high-temporal and spatial resolution tir image data

Remote sensing imagery to monitor global biophysical dynamics requires the availability of thermal infrared data at high temporal and spatial resolution because of the rapid development of crops during the growing season and the fragmentation of most agricultural landscapes. Conversely, no single sensor meets these combined requirements. Data fusion approaches offer an alternative to exploit observations from multiple sensors, providing data sets with better properties. A novel spatio-temporal data fusion model based on constrained algorithms denoted as multisensor multiresolution technique (MMT) was developed and applied to generate TIR synthetic image data at both temporal and spatial high resolution. Firstly, an adaptive radiance model is applied based on spectral unmixing analysis of . TIR radiance data at TOA (top of atmosphere) collected by MODIS daily 1-km and Landsat – TIRS 16-day sampled at 30-m resolution are used to generate synthetic daily radiance images at TOA at 30-m spatial resolution. The next step consists of unmixing the 30 m (now lower resolution) images using the information about their pixel land-cover composition from co-registered images at higher spatial resolution. In our case study, TIR synthesized data were unmixed to the Sentinel 2 MSI with 10 m resolution. The constrained unmixing preserves all the available radiometric information of the 30 m images and involves the optimization of the number of land-cover classes and the size of the moving window for spatial unmixing. Results are still being evaluated, for the quality of the data streams required to our approach.
Institutional Knowledge at Singapore Management University Intraday Price Discovery in Emerging Equity Market: Analysis of SET50 Index, SET 50 Index Futures and THAIDEX SET50 (TDEX)

This study employs Vector Error Correction Model (VECM), information share and conditional information share methods to investigate price discovery in SET50 Index (cash index), SET50 Index Futures (futures index) and ThaiDex SET50 (exchange traded fund). Our findings indicate that there exists a long run relationship among three markets and a multi-market trading of derivatives markets and its underlying asset helps improve price efficiency. With respect to the degree of price formation process, SET50 Index Futures contributes most in price discovery process, followed by SET50 Index and ThaiDex SET50. share while SET50 Index and TDEX contribute approximately 35% and 10%, respectively. Panel C shows the upper and lower bounds of information shares. After permuting all orderings of variables in the Cholesky decomposition, the results demonstrate that the bounds of information shares for both upper and lower bounds of each market are not sensitive to the alternative orderings of variables. The results from the conditional information share reemphasis the important roles of futures, exchange traded funds and cash market index in price discovery process. This study investigates the price discovery during the overlapping trading hours of SET50 Index ( cash index ), SET50 Index Futures ( futures index ) and ThaiDex SET50 ( exchange traded fund). We employ three methods to document dynamic price discovery; Vector Error Correction Model (VECM), information share and conditional information share. Our results indicate that there exists the long run relationship among three markets.
