Taxation and housing markets with search frictions
Year: 2019

Housing taxation is an important policy instrument that shapes households' choices about homeownership and renting as well as the evolution of the housing market. We study the effects of housing taxation in a model with search and matching frictions in the property market and a competitive rental market. We show a new transmission channel for a housing tax reform that works through a 'shifting' effect from landlords to tenants. We calibrate the model in order to estimate the long run effects of the recent Italian housing market taxation reforms and the extent of property tax capitalization on house prices. We show that property taxation on owner occupied dwellings has a negative effect on property and rental prices, whereas taxes on second homes have opposite qualitative effects. The simultaneous increase in both these instruments may mitigate the dynamics of prices and rents as well as the change in the ratio between the share of owners and renters, leading to a partial capitalization taxation on prices.
Topological Characterization of Periodically Driven Quantum Systems
Year: 2010

Topological properties of physical systems can lead to robust behaviors that are insensitive to microscopic details. Such topologically robust phenomena are not limited to static systems but can also appear in driven quantum systems. In this paper, we show that the Floquet operators of periodically driven systems can be divided into topologically distinct (homotopy) classes, and give a simple physical interpretation of this classification in terms of the spectra of Floquet operators. Using this picture, we provide an intuitive understanding of the well known phenomenon of quantized adiabatic pumping. Systems whose Floquet operators belong to the trivial class simulate the dynamics generated by time independent Hamiltonians, which can be topologically classified according to the schemes developed for static systems. We demonstrate these principles through an example of a periodically driven two dimensional hexagonal lattice model which exhibits several topological phases. Remarkably, one of these phases supports chiral edge modes even though the bulk is topologically trivial.

Year: 2016

Opisthorchiasis is a health problem in rural communities of Thailand, particularly in the northeast and north regions. Therefore, this study aimed to investigate raw fish consuming behavior related to liver fluke infection among the population at risk for opisthorchiasis and cholangiocarcinoma (CCA) A cross sectional descriptive study was conducted in Meuang Yang district, Nakhon Ratchasima province, northeast Thailand, between June and October 2015. Participants were screened for CCA, and samples who had a high score of CCA risk were purposively selected. A predesigned questionnaire was utilized to collect the data from all participants. X2 test was used for analysis of associations between demographic data and raw fish consumption. The results revealed that participants had past histories of stool examination (33.0% liver fluke infection (21.0% praziquantel use (24.0% raw fish consumption (78.0% relatives family consuming raw fish (73.0% and relatives family with CCA (3.0% Participants consumed several dished related to liver fluke infection, mainly raw fermented fish (13.0% under smoked catfish (5.00% raw pickled fish (4.00% and raw spicy minced fish salad (3.00% The most common types of cyprinoid fish were Barbodes gonionotus (39% Hampala dispar (38% Puntius brevis (37% Cyclocheilichthys armatus (33% Puntioplites proctozysron (32% and Luciosoma bleekeri (30% respectively. Participants had a low level of knowledge (mean=3.79, SD=0.74) moderate attitude (mean=7.31, SD=7.31) and practice (mean=38.64, SD=6.95) regarding liver fluke prevention and control. Demographic variables like age >36 years old; X2 test=17.794, p value=0.001) education (primary school; X2 test=18.952, p value=0.001) marital status (married; X2 test=12.399, p value=0.002) and income <5,000 baht; X2 test=27.757, p value=0.015) were significantly associated with raw fish consumption. This result indicates that the population had risk consumption for liver fluke infection particularly of various cyprinoid fishes that are 2nd intermediate hosts. Therefore, health education is required to improve their behavior.

A frequency reconfigurable slot antenna using PIN diodes
Venue: 2009 Asia Pacific Microwave Conference
Year: 2009

In this paper, a frequency reconfigurable slot antenna using PIN diodes is proposed. The proposed structure is based on an open end straight slot line on the bottom layer and a microstrip line input on the top layer. By means of the two PIN diodes and the associated dc bias network, the proposed antenna has the ability to alternatively switch the operating frequency. The proposed antenna is made of FR4 substrate and use commercial PIN diodes. The measured results agree with simulated results, and further verify the design concept. The proposed antenna can be applied in the commercial wireless communication due to its low cost and low profile properties.
A Systematic Review and Meta Analysis on Microsurgical Safety and Efficacy of Profunda Artery Perforator Flap in Breast Reconstruction
Venue: Journal of oncology
Year: 2019

The profunda artery perforator (PAP) flap was first applied in breast reconstruction in 2010 by Robert J. Allen. It provided an alternative for autologous breast reconstruction in addition to traditional donor sites. Currently, literature reporting its microsurgical safety and efficacy is relatively sparse and heterogeneous.  To clarify the evidence regarding microsurgical safety and efficacy of PAP flap in breast reconstruction, which may contribute to future surgical decision making.  Multiple databases were systematically searched by two independent reviewers. The result was statistically analyzed with Meta command of R GUI 3.5.1. The proportions with 95% confidence intervals (CIs) were calculated by using random effect model.  There were 12 studies including 516 PAP flaps meeting the inclusion criteria. The pooled surgical success rate was 99% (95% CI: 97% 100% and overall rate of complications was 23% (95% CI: 18% 27% The most common individual complication was wound dehiscence with incidence of 6% (95% CI: 4% 9% The seroma rate was 2% (95%CI: 0% 6% The hematoma rate was 1% (95% CI: 0% 2% The partial necrosis rate was 2% (95% CI: 0% 5% The rate of total flap loss was 1% (95% CI: 0% 3%  To date, this study is the first meta analysis of microsurgical efficacy and safety evaluation of the PAP flap in breast reconstruction. This present work confirmed that the PAP flap is safe and reliable in breast reconstruction with high success rate, but a relatively low complication rate. Moreover, it might be more than an alternative to the deep inferior epigastric perforator flap (DIEP) in microsurgical breast reconstruction in selected patients.
An Effective Way for Brain Tumor Detection using Morphological Operations and SVM Classifier
Year: 2017

13 Abstract Brain is highly specialized organ which helps as control center for functions of the body. Tumor is quick uncontrolled growth of cells. MRI imaging plays an important role in brain tumor analysis and diagnosis. Two dime nsional MRI images are used to process and identify tumor r egion. MRI images are generally degraded with different types of noise. So these noise are removed using pre processing techni ques which improves the visual appearance of image without dis turbing original image attributes. Pre Processing will be p erformed at early stages before dealing with tumor detection an d segmentation. MRI image segmentation will be perfor med to accurately identify region of interest from the images. Feature extraction will be done to capture visual content o f image by using GLCM and region prop method. Later segmentation, shape and texture features associated will image wi ll be extracted. Based on these extracted features brain image will be classified into abnormal and normal. The performance of this system is evaluated based on training performance c lassification accuracies to provide the precise and accurate resu lts.
Using visualizations to review a group's interaction dynamics
Venue: CHI Extended Abstracts
Year: 2006

We present a visualization system for reviewing the turn taking patterns in a face to face meeting. Without the need to directly observe a group, a user can use the system to gain insight into the interaction dynamics of a meeting. We evaluated the visualizations by asking outside observers to make qualitative judgments about the individuals represented visually, and then compared their assessments to our own, made from direct observation of the meetings.
Real time, label free, intraoperative visualization of peripheral nerves and micro vasculatures using multimodal optical imaging techniques.
Venue: Biomedical optics express
Year: 2018

Accurate, real time identification and display of critical anatomic structures, such as the nerve and vasculature structures, are critical for reducing complications and improving surgical outcomes. Human vision is frequently limited in clearly distinguishing and contrasting these structures. We present a novel imaging system, which enables noninvasive visualization of critical anatomic structures during surgical dissection. Peripheral nerves are visualized by a snapshot polarimetry that calculates the anisotropic optical properties. Vascular structures, both venous and arterial, are identified and monitored in real time using a near infrared laser speckle contrast imaging. We evaluate the system by performing in vivo animal studies with qualitative comparison by contrast agent aided fluorescence imaging.

Heroic ecologies: embodied heroic leadership and sustainable futures
Year: 2017

The purpose of this paper is to demonstrate heroism as an embodied system of leadership and well being. Heroic leadership is presented as a baseline for sustainable futures and global health.  This paper presents an embodied reading of heroic leadership and its sustainable development across five stages. It outlines its core functions, its grounding in self leadership through physical and mental trauma and its holistic benefits, resulting in the development of the Heroic Leadership Embodiment and Sustainable Development (HLESD) model. The efficacy of HLESD is demonstrated in an empirical case study of heroism promotion and education: the Hero Construction Company and the Heroic Imagination Project.  Heroic leadership is revealed as an emergent, dynamic and distributed form of sustainable development.  This paper demonstrates the critical connections between heroism, sustainability, embodied leadership and well being and how they stand to benefit from each other, individuals and communities at large.  The implementation of HLESD in educational, counselling and broader contexts in consultation with a wide range of professionals stands to offer significant benefits to pedagogies, clinical practice, holistic therapies and twenty first century societies, at both the community and policy level.  The emerging field of heroism science and the use of heroic leadership as an interdisciplinary tool is a novel approach to well being, which holds immense potential for the imagining and fostering of sustainable personal and collective futures.

Dynamic Neural Turing Machine with Soft and Hard Addressing Schemes
Venue: ArXiv
Year: 2016

We extend neural Turing machine (NTM) model into a dynamic neural Turing machine (D NTM) by introducing a trainable memory addressing scheme. This addressing scheme maintains for each memory cell two separate vectors, content and address vectors. This allows the D NTM to learn a wide variety of location based addressing strategies including both linear and nonlinear ones. We implement the D NTM with both continuous, differentiable and discrete, non differentiable read/write mechanisms. We investigate the mechanisms and effects of learning to read and write into a memory through experiments on Facebook bAbI tasks using both a feedforward and GRUcontroller. The D NTM is evaluated on a set of Facebook bAbI tasks and shown to outperform NTM and LSTM baselines. We have done extensive analysis of our model and different variations of NTM on bAbI task. We also provide further experimental results on sequential pMNIST, Stanford Natural Language Inference, associative recall and copy tasks.

Siantar Top Tbk) Dibawah bimbingan Pembimbing Skripsi I Ibu Nurlaila Harahap, SE, MA dan Pembimbing Skripsi II Ibu Kusmilawaty, SE, M.Ak. Modal kerja merupakan unsur yang sangatpenting bagi perusahaan karena tanpa modal kerja yang cukup, aktivitas operasional perusahaan tidak dapat dilangsungkan. Dengan berkembangnya dunia usaha yang semakin pesat saat ini sehingga terjadi persaingan yang ketat diantara perusahaan sejenis, memperoleh kecukupan modal tersebut menjadi faktor utama yang perlu diperhatikan. Untuk dapat bersaing dengan perusahaan lainnya, perusahaan harus dapat mengelola seluruh kekayaan, kewajinan dan modal yang dimiliki semaksimal mungkin sehingga kegiatan operasional perusahaan dapat berjalan baik. Analisis dan penggunaan modal kerja, rasio likuiditas, current ratio, sering digunakan sebagai indikator untuk menilai efektivitas dan efisiensi modal kerja suatu perusahaan dan mengukur kemampuannya dalam melunasi seluruh kewajiban jangka pendeknya. Penelitian ini dilakukan pada perusahaan industri makanan ringan yakni PT. Siantar Top Tbk untuk periode 2011 2015. Tujuan penelitian ini adalah untuk mengetahui laporan sumber dan penggunaan modal kerja dalam meningkatkan likuiditas perusahaan. Metode penelitian yang digunakan adalah metode kualitatif deskriptif, yaitu metode yang berusaha mengumpulkan data yang sesuai keadaan yang sebenarnya, menyajikan dan menganalisisnya sehingga dapat memberikan perbandingan yang cukup jelas mengenai objek yang diteliti dan kemudian dapat ditarik suatu kesimpulan. Dari hasil penelitian dan pembahasan yang dilakukan, penulis melihat bahwa sumber modal kerja terbesar perusahaan berasal dari Laba bersih. Sedangkan sumber lainnya berasal dari berkurangnya asset tetap, bertambahnya kewajiban imbalan pasca kerja dan bertambahnya kewajiban jangka panjang perusahaan. Sedangkan penggunaan modal kerja ditujukan untuk pembayaran cash deviden, pembelian aktiva tetap, dan membayar kewajiban jangka panjang. Pengelolaan Sumber dan Penggunaan Modal kerja perusahaan pada kurun waktu 5 tahun yaitu tahun 2011 sampai dengan 2015 sudah cukup baik. Jika dilihat hasil rasio likuiditas, rasio likuiditas PT. Siantar Top Tbk sudah cukup baik. Hasil dari rasio likuiditas PT. Siantar Top Tbk menunjukkan bahwa dari kurun waktu 5 (lima) tahun perusahaan hanya mengalami kenaikan/peningkatan likuiditas dari tahun 2011 ke tahun 2012 yaitu sebesar 2,22 dan 2,76. Sedangkan pada tiga tahun lainnya yaitu 2013, 2014, dan 2015 rasio likuiditas lebih rendah yaitu sebesar 2,44, 2,09 dan 2,37. Kata Kunci Sumber dan Penggunaan Modal Kerja, Likuiditas
Moving object tracking in video surveillance using YOLOv3 and MeanShift
Venue: International Conference on Graphic and Image Processing
Year: 2019

Video surveillance is widely used and plays a huge role in society. Due to surveillance videos are often continuously produced, using these videos to track objects is a challenge for conventional moving object tracking methods. In this paper, in order to deal with the fast moving object and the problem of target occlusion, we propose an object tracking method based on YOLOv3 and MeanShift combined with Kalman filter aiming to improve the speed and accuracy of tracking. We use YOLOv3 to realize the detection and use the MeanShift combined with Kalman filter to track the target. The results of the experiment show that our method has achieved good results.
Binary Constrained Deep Hashing Network for Image Retrieval without Human Intervention
Venue: ArXiv
Year: 2018

Learning compact binary codes for image retrieval problem using deep neural networks has attracted increasing attention recently. However, training deep hashing networks is challenging due to the binary constraints on the hash codes, the similarity preserving properties, and the requirement for a vast amount of labelled images. To the best of our knowledge, none of the existing methods has tackled all of these challenges completely in a unified framework. In this work, we propose a novel end toend deep hashing approach, which is trained to produce binary codes directly from image pixels without human intervention. In particular, our main contribution is to propose a novel pairwise loss function, which simultaneously encodes the distances between pairs of binary codes, and the binary quantization error. We propose an efficient parameter learning algorithm for this loss function. In addition, to provide similar/dissimilar images for our pairwise loss function, we exploit 3D models reconstructed from unlabeled images for automatic generation of enormous similar/dissimilar pairs. Extensive experiments on three image retrieval benchmark datasets demonstrate the superior performance of the proposed method.
