A Novel Model, Recurrent Fuzzy Associative Memory, for Recognizing Time-Series Patterns Contained Ambiguity and Its Application (2004)

본 논문에서는 모호성을 포함하고 있는 시계열 패턴인식을 위한 새로운 인식모델인 순환퍼지기억장치를 제안한다. 순환퍼지기억장치는 기존의 퍼지기억장치에 순차적인 입력패턴를 처리하고 시간적 관련성을 표현할 수 있는 순환층을 추가함으로써 확장된 모델이다. 본 논문에서 제안하는 순환퍼지기억장치는 입력과 출력사이의 관련정도를 설정하기 위해 헤비안 방식의 학습알고리즘을 사용한다. 그리고 순환퍼지기억장치의 순환층에 필요한 가중치를 학습하기 위해서 오류역전파 알고리즘을 이용한다. 본 논문에서는 제안하는 모델을 음성신호의 경계를 추출하는 문제에 적용하여 성능을 평가한다. This paper proposes a novel recognition model, a recurrent fuzzy associative memory(RFAM), for recognizing time-series patterns contained an ambiguity. RFAM is basically extended from FAM(Fuzzy Associative memory) by adding a recurrent layer which can be used to deal with sequential input patterns and to characterize their temporal relations. RFAM provides a Hebbian-style learning method which establishes the degree of association between input and output. The error back-propagation algorithm is also adopted to train the weights of the recurrent layer of RFAM. To evaluate the performance of the proposed model, we applied it to a word boundary detection problem of speech signal.
A low-power analog CMOS vector quantizer (2002)

The authors describe the implementation and performance of what might be termed a 'Vector A/D Converter'. The IC stores a codebook of vectors on-chip, accepts a 16-element analog vector at the input, calculates the Euclidean distance between the input and all codevectors (referred to as global search), and outputs an 8-bit code to index the codevector closest to the input prompt. At a 5 MHz clock rate it dissipates less than 50 mW to quantize 16 element analog vectors once every 10 clock periods, giving a 30 Hz frame rate for a 512*512 pixel gray scale image.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The c-erbA alpha-encoded thyroid hormone receptor is phosphorylated in its amino terminal domain by casein kinase II. (1989)

The c-erbA alpha progenitor of the v-erbA oncogene of avian erythroblastosis virus (AEV) encodes a nuclear receptor for the thyroid hormone triiodothyronine (T3) which acts as a ligand-dependent transcription factor. As previously reported (Goldberg et al., EMBO J., 7, 2425-2433), the 46 kd chicken c-erbA alpha-encoded T3 receptor (ck-ErbA alpha) is phosphorylated at two major sites. Only one of these sites (Ser28/Ser29) is retained in the v-erbA-encoded P75gag-v-erbA protein. We report here the identification of the second phosphorylation site of ck-ErbA alpha as a single serine residue localized at position 12. We propose that casein kinase II, a protein kinase distributed in the cytosolic and nuclear compartments of a number of different tissues, is responsible for serine 12 phosphorylation on the following grounds. First, serine 12 is part of a sequence containing multiple acidic amino-acids, a feature common to all sites phosphorylated by casein kinase II in physiological substrates. Second, ck-ErbA alpha was found to be phosphorylated by purified casein kinase II in vitro at the same site, as defined by two-dimensional mapping experiments, as that observed in vivo. Third, conversion of serine 12 into an unphosphorylatable alanine residue by site directed mutagenesis abolishes the phosphorylation of ck-ErbA alpha by casein kinase II in vitro. Phosphorylation of serine 12 is likely to play a role in the modulation of ErbA alpha function since both serine 12 and the casein kinase II phosphorylation sequence motif are phylogenetically conserved in all known members of the c-erbA alpha gene family encoding T3 binding proteins. The codon specifying serine 12 in ck-ErbA alpha being precisely the point where recombination between gag and ck-c-erbA alpha occurred to generate v-erbA, our results furthermore suggest that deletion of serine 12 could contribute to the oncogenic activation of v-erbA.

A sense of touch begins to gather momentum (1981)

An extensive survey of over 300 reports worldwide shows that the state‐of‐the‐art in tactile sensing — defined as continuously variable touch sensing over an area where there is special resolution — is primitive. Only now is a new level of sophistication beginning to appear. However, for industrial systems the simplest may prove to be the most reliable.
Peranan Ibu dalam Pemeliharaan Kesehatan Gigi Anak dengan Status Karies Anak Usia Sekolah Dasar (2015)

Karies merupakan masalah gigi yang paling sering ditemukan pada anak usia sekolah dasar. Karies gigi adalah suatu penyakit infeksi yang merupakan proses demineralisasi progresif pada jaringan keras permukaan mahkota dan akar gigi yang sebenarnya dapat dicegah. Penyebab dari karies ini adalah adanya aktivitas mikroba dalam suatu karbohidrat yang dapat difermentasikan. Demineralisasi yang terjadi di jaringan keras gigi ini kemudian diikuti oleh kerusakan bahan organiknya. Invasi bakteri, kematian pulpa dan penyebaran infeksi ke jaringan periapikal dapat menyebabkan timbulnya rasa sakit. Rasa sakit tersebut dapat bertambah akibat mengonsumsi makanan atau minuman manis, bersuhu panas ataupun dingin. Orang tua sangat berperan dalam membentuk perilaku anak. Sikap dan perilaku orang tua, terutama ibu, dalam pemeliharaan kesehatan gigi memberi pengaruh yang cukup signifikan terhadap perilaku anak. Walaupun masih memiliki gigi sulung, orang tua harus memberikan perhatian serius pada anak. Pertumbuhan gigi permanen anak ditentukan oleh kondisi gigi sulung anak. Namun, masih banyak orang tua yang beranggapan bahwa gigi sulung hanya sementara dan akan digantikan oleh gigi permanen, sehingga mereka sering menganggap bahwa kerusakan pada gigi sulung bukan merupakan suatu masalah. Berdasarkan hal tersebut, peranan orang tua dalam memelihara kesehatan gigi merupakan salah satu faktor risiko yang menyebabkan karies pada anak.

Surface size, curvature analysis, and assessment of knee joint incongruity with MRI in vivo (2002)

Abstract The purpose of this study was to develop an MR‐based technique for quantitative analysis of joint surface size, surface curvature, and joint incongruity and to assess its reproducibility under in vivo imaging conditions. The surface areas were determined after 3D reconstruction of the joint by triangulation and the incongruity by Gaussian curvature analysis. The precision was tested by analyzing four replicated MRI datasets of human knees in 14 individuals. The algorithms were shown to produce accurate data in geometric test objects. The interscan precision was <4% (CV%) for surface area, 2.9–5.7 m −1 (SD) for the mean principal curvature, and 4.1–7.4 m −1 for congruence indices. Incongruity was highest in the femoropatellar joint (79.7 m −1 ) and lowest in the medial femorotibial joint (28.6 m −1 ). This technique will permit identification of the specific role of surface size, curvature, and incongruity as potential risk factors for osteoarthritis.

Tetra-<i>n</i>-butylammonium Fluoride as an Efficient Transesterification Catalyst for Functionalizing Cyclic Carbonates and Aliphatic Polycarbonates (2013)

We have developed a general method for the functionalization of cyclic carbonate monomers having a pentafluorophenyl ester substituent at the 5-position (MTC-OC<sub>6</sub>F<sub>5</sub>), as well as the postpolymerization modification of the subsequent polymer, poly(MTC-OC<sub>6</sub>F<sub>5</sub>), with alcohols. The transesterifications are achieved under mild conditions using catalytic tetra-<i>n</i>-butylammonium fluoride (TBAF) as the nucleophilic acyl transfer agent. As an organic-soluble form of fluoride, TBAF loadings as low as 5 mol % were sufficient in bringing about high conversions at room temperature. The mild reaction conditions preserved the integrity of the sensitive carbonate moieties even without the use of Schlenk techniques. In addition to commercial TBAF solutions, we also found solid-supported forms of TBAF to be effective for transesterification, thus enabling facile postreaction workup and purification. More importantly, with only minor adjustments to the reaction conditions, we show that TBAF also promotes the postpolymerization modification of poly(MTC-OC<sub>6</sub>F<sub>5</sub>), whereby fluoride-mediated transesterification with various alcohols proceeded quantitatively across the pendant pentafluorophenyl esters. Synthesizing a series of pendant ester-functionalized polycarbonates from a common precursor polymer was previously unattainable with existing methods, an issue that is now resolved by the current work.
Effects of Dimple Size and Depth on Golf Ball Aerodynamic Performance (2003)

Based on the three-dimensional CFD modeling method reported previously, systematic computational sensitivity studies of how the changes of dimple size, depth, number, coverage area, and distribution pattern will affect the golf ball aerodynamic performance have been made by considering those variables individually and then collectively. By using a new golf ball surface design with 344 identical single-sized circular dimples, but keeping the dimple distribution pattern and the dimple diameter unchanged, the dimple depth effect was first investigated by varying the dimple depressions from shallow to deep, and an optimum value corresponding to minimum drag loss has been found. Using the balls with same optimum dimple depth, drag results show the tendency of decreasing as the dimple diameter increases from small to large until a limit is reached. Beyond this limit, drag coefficient will remain to be a constant even with the further increases of the dimple diameter. Ball drag and lift results obtained and presented are not only for the whole ball, but also separately for the dimple occupied area and the dimple-free cage area. Influence of ball backspin motion to the magnitude of the dimple’s optimum depth value was found to be insignificant. Flow field solutions of velocity vectors, trace lines, pressure, and turbulence intensity have also been obtained, and some are used to show how the changes of dimple depth, dimple diameter, as well as the ball backspin motion, will affect the wake formation behind the ball both in size and shape.
An efficient method for broadband seismic illumination and resolution analyses (2015)

Summary We develop an efficient method to calculate the broadband seismic illumination and resolution. The point spreading function of seismic image contains the full information for illumination and resolution analyses. Physically, it is the image of a point scatter. Therefore we can obtain the illumination information by calculating the point spreading function. We develop a method to better calculate the point spreading function. The scattered waves from background structure are eliminated, Noise from higher-order inter-scatter multiples are investigated and properly avoided. By converting the point spreading function to the wavenumber domain, methods for illumination and resolution analyses in angle domain are also discussed.
A Two-Channel Asynchronous SAR ADC With Metastable-Then-Set Algorithm (2011)

A low power dual-channel asynchronous successive approximation register (ASAR) analog-to-digital converter (ADC) is presented. A metastable-then-set (MTS) algorithm is proposed with the aim of eliminating unnecessary decision operations in ASAR and its effects on power consumption and performance have been measured. The proposed flag synchronization technique minimizes the crosstalk between two asynchronous ADCs. A prototype ADC was implemented in 0.13-μm CMOS technology and operated under a 1.2 V supply. At a sampling rate of 17.5 MS/s, the ADC achieves a peak signal-to-noise and distortion ratio of 51.3 dB at 1.73 MHz input frequency. The measured total power dissipation of a single channel ADC is 570 μW and the figure of merit is 103 fJ/step.
Neste Oy gives product stability as much attention as conversion in visbreaking (1982)

This article describes how Finland's national oil company uses visbreaking in refining operations. Presents tables on soaking drum visbreaking gases and naphtha; and graphs of yields of distillates indicating stability, and light distillates yields with cracking degree. Goal is to run a unit to a defined stability limit resulting in optimal storage-stability of blended fuel oils. Suggests that the most important property of visbreaking residues is stability, which cannot be improved by blending with even the best cutter stocks. Cautions that viscosity of heavy fuel oils increases during long-time storage.

Tras el oportuno tratamiento estadistico observamos igualmente que no existian diferencias estadisticamente significativas entre los alumnos de los tres cursos de la especialidad. Finalmente consideramos que es util el desarrollo de esta metodologia en el ambito de la investigacion docente con vistas a establecer para cada unidad docente el patron de referencia de sus estilos predominantes de aprendizaje, pudiendo completarse en futuros estudios con un analisis longitudinal que determine la influencia que la edad puede desarrollar en las preferencias de los mismos alumnos.
Filter Backwashing Tests and Upflow Equalization (1968)

Suspended solids are determined in backwash samples collected every 15 sec at critical points in filters throughout the backwash operation. Eight plants were visited to observe some 23 variables. Cleansing action is decidedly nonuniform, being greatest under the sides of the troughs and decreasing toward the intertrough median. Corners generally washed most poorly. Disparity in upflow is caused by the directional influence of the troughs which negate the uniformity expected from the underdrains. Although various correctives are considered, only a V-shaped functionally perforated guidance baffle can be permanently effective.
Armed Separatism and Muslim Autonomy in the Southern Philippines (1999)

From 1972 to 1980, a ferocious war raged throughout the southern Philippines between Muslim separatist rebels and the Philippine military. An estimated 120,000 people died in the fighting, which also created one million internal refugees and caused more than 100,000 Philippine Muslims to flee to Malaysia. That war ended in a stalemate and for the next 18 years an uneasy and fragile cease-fire existed - one periodically broken by armed clashes between the military and separatist fighters who remain under arms in remote camps. A 1996 peace agreement between the Philippine government and the main rebel faction represents the first real progress towards a genuine settlement of the conflict and substantial political autonomy for Philippine Muslims. This article traces the remote and proximate causes of the Philippine Muslim (or Bangsamoro) rebellion and its consequences for ordinary Muslims.
Dual-V CC 8T-bitcell SRAM array in 22nm tri-gate CMOS for energy-efficient operation across wide dynamic voltage range (2013)

A 14KB 8T-bitcell SRAM array is demonstrated in 22nm tri-gate CMOS with fine-grain dual-VCC assist techniques. VMIN limiting 8T-bitcell nodes are boosted selectively during read and write to improve overall chip-VMIN. Measurements show 130-270mV lower VMIN with 27-46% lower power at 0.4-1.6GHz for varying amounts of boosting, array activity and voltage regulator efficiency.
Effect of overexpression of HOX genes on its invasive tendency in cerebral glioma (2015)

Transcription factors encoded by <i>HOX</i> genes are vital in the determination of cell fate and identity during embryonic development. In certain malignancies, <i>HOX</i> genes also behave as oncogenes. The present study demonstrated suppression of the invasive tendency of glioblastoma multiforme U-118 and U-138 cells by the introduction of the antisense fragments of <i>HOXA6</i> and <i>B13</i> genes using electroporation. The invasion index indicated 79 and 72% reductions in the invasive ability of antisense <i>HOXA6</i> and <i>B13</i>, respectively. No significant differences in the invasive index of the parental and mock cells of each <i>HOX</i> gene were observed (invasive index, 0.75-0.91; P=0.05). A reduction in invasion tendency was also observed following betulinic acid (BA) treatment: The results from the matrigel assay analysis clearly demonstrated a significant inhibition in the invasive behaviour of U-118 and U-138 cell lines from day 15 following BA treatment, with a maximum effect on day 30. The invasion index demonstrated 62 and 65% reductions in invasion ability in the U-118 and U-138 cell lines, respectively. The suppression of <i>HOXC6</i> and <i>B13</i> expression by the introduction of the corresponding antisense fragments in addition to BA reduced invasion tendency in U-118 and U-138 cell lines. The mechanism underlying the association between the <i>HOX</i> gene and invasive behavior in glioma cells is yet to be understood. However, the anti-invasive behavior of BA may aid understanding of the mechanism in future studies.
Phosphoinositide 3-OH Kinase Activates the β2Integrin Adhesion Pathway and Induces Membrane Recruitment of Cytohesin-1 (1998)

Signal transduction through phosphoinositide 3-OH kinase (PI 3-kinase) has been implicated in the regulation of lymphocyte adhesion mediated by integrin receptors. Cellular phosphorylation products of PI 3-kinases interact with a subset of pleckstrin homology (PH) domains, a module that has been shown to recruit proteins to cellular membranes. We have recently identified cytohesin-1, a cytoplasmic regulator of beta2 integrin adhesion to intercellular adhesion molecule 1. We describe here that expression of a constitutively active PI 3-kinase is sufficient for the activation of Jurkat cell adhesion to intercellular adhesion molecule 1, and for enhanced membrane association of cytohesin-1. Up-regulation of cell adhesion by PI 3-kinase and membrane association of endogenous cytohesin-1 is abrogated by overexpression of the isolated cytohesin-1 PH domain, but not by a mutant of the PH domain which fails to associate with the plasma membrane. The PH domain of Bruton's tyrosine kinase (Btk), although strongly associated with the plasma membrane, had no effect on either membrane recruitment of cytohesin-1 or on induction of adhesion by PI 3-kinase. Having delineated the critical steps of the beta2 integrin activation pathway by biochemical and functional analyses, we conclude that PI 3-kinase activates inside-out signaling of beta2 integrins at least partially through cytohesin-1.
Simultaneously Color-Depth Super-Resolution with Conditional Generative Adversarial Network (2017)

Recently, Generative Adversarial Network (GAN) has been found wide applications in style transfer, image-to-image translation and image super-resolution. In this paper, a color-depth conditional GAN is proposed to concurrently resolve the problems of depth super-resolution and color super-resolution in 3D videos. Firstly, given the low-resolution depth image and low-resolution color image, a generative network is proposed to leverage mutual information of color image and depth image to enhance each other in consideration of the geometry structural dependency of color-depth image in the same scene. Secondly, three loss functions, including data loss, total variation loss, and 8-connected gradient difference loss are introduced to train this generative network in order to keep generated images close to the real ones, in addition to the adversarial loss. Experimental results demonstrate that the proposed approach produces high-quality color image and depth image from low-quality image pair, and it is superior to several other leading methods. Besides, we use the same neural network framework to resolve the problem of image smoothing and edge detection at the same time.
