A design guide for 3-stage CMOS nested Gm-C operational amplifier with area or current minimization

A systematic design guide for 3-stage CMOS operational amplifier (op amp) with nested Gm-C frequency compensation (NGCC) was proposed. With the given specification such as gain-bandwidth (GB), the ratio of high frequency pole to GB, phase margin, input common-mode range, and load capacitance, the guide generates the design parameters that minimize total area or current. The test chip designed by the proposed guide was fabricated with a 0.18-mum CMOS process. The simulation results show reasonable performances with 1.2-V supply voltage, and the measurement results show low-voltage operations of the designed op amps with 0.6-V supply voltage.
A case of autoimmune polyglandular syndrome type III with a slowly progressive form of type‐1 diabetes mellitus that manifested in the course of autoimmune diseases

Autoimmune polyglandular syndrome (APS) is a group of disorders with multiple autoimmune endocrinopathies. Although the exact cause is not clear, genetic background and autoimmunity are known to be associated with its pathogenesis. There are three types of APS, some of which are often complicated by type-1 diabetes mellitus or Sjögren’s syndrome. However, Sjögren’s syndrome is an autoimmune exocrinopathy and is also complicated by various autoimmune disorders. Here we present a rare case of APS type III with a slowly progressive form of type-1 diabetes mellitus complicated by Sjögren’s syndrome, autoimmune thyroiditis, and probable systemic lupus erythematosus.
Oxidation of lindane in contaminated water under solar irradiation in the presence of photocatalyst and oxidizing agents

of lindane varying from 0.05×10 –2 M to 1.0×10 –2 M. The photooxidation and photocatalytic oxidation are studied in the presence of H2O2/K2Cr2O7 to check the effect of oxidizing agents on the rate of oxidation. The higher rate of oxidation is observed in the presence of H2O2 when compared to K2Cr2O7 in photocatalysis. The decrease in the concentration of lindane during oxidation is also followed by UV-visible absorption studies. The oxidation of lindane follows the first order kinetics and the value of the rate constant k, as calculated, is 0.43×10 –4 s –1 .
Stochastic optimisation methods and pattern search algorithms for augmented reality videoconferencing

This dissertation introduces a novel system for collaborative telepresence based on the mutual integration of two users’ surroundings into a consensus reality. Other than in classical videoconferences or immersive telepresence systems, there is no separation between the users’ environments. Instead, the users have the impression of standing in their own room and see their conversation partner rendered through a head mounted display, as if they shared the same physical space. The following pages describe the overall system architecture required to achieve this effect and provide an examination of the two core challenges arising from this interaction scenario. In order to integrate two differently shaped rooms into a shared environment, the position of the users and the layout of the floorspace must be aligned carefully. At first, the human pose tracking is considered in detail. This tracking of posture can be understood as a high dimensional optimisation problem in a stochastic framework. The central problem of approximating the observation likelihood of a given pose is discussed in detail. Furthermore, the integration of the resulting approximation function into an Annealing Particle Filter is described and evaluated extensively. Once the users’ poses and positions are known, their environment can be merged into a shared consensus reality. This leads to a second optimisation problem. Since the participating rooms can have very different layouts, discontinuities between the two spaces can destroy the illusion of co-presence. The problem is expressed through a series of energy functions, which can be approached as a maximisation problem. The design of these energy terms is discussed in detail and a thorough examination of their characteristics is given. Common to both topics is the expression of otherwise intractable problems in a global optimisation framework and their central role in driving the envisioned telepresence system. While the creation of the consensus reality sets the foundation for projecting two rooms into a common workspace, the human pose tracking then drives the interaction with virtual content. The goal is to provide a channel for communication over distance which incorporates not only visual and auditory cues, but allows the users to interact naturally by sharing the same physical space even if they are on different continents.
Cross‐Talk between Aging and Cancer

Abstract: The risk of having cancer increases with age probably because progenitor cells from mature organisms accumulate enough molecular lesions to evade the homeostatic control of their tissular contexts. Molecular lesions can be genetic (mutations, deletions, or translocations) and/or epigenetic. Epigenetic signaling, including DNA methylation and histone modification, is essential for normal development and becomes altered during Aging and by cancer. Several epigenetic alterations, such as global hypomethylation and CpG island hypermethylation, are progressively accumulated during Aging and directly contribute to cell transformation. Intriguingly, others, such as those involved in the control of telomere length and several epigenetic enzymes belonging to the family of nicotinamide adenine dinucleotide (NAD)(+) dependent deacetylases known as sirtuins, exhibit a well‐defined progression during Aging that is dramatically reverted in transformed cells. We discuss the biological significance of both groups of epigenetic modifications in terms of their relative contribution to ontogenic development, senescence, and cell proliferation.
]JERS-1 SAR data in forest biomass mapping in northern taiga zone

Forest biomass mapping was studied in a site in northern Finland (latitude 66deg). Two JERS SAR scenes that were acquired in a dry period were used. Locally derived linear regression models between forest stem volume and L-band SAR amplitude produced correlation coefficients of 0.7. An earlier regression model, which had been derived in a site in southern Finland, produced under-estimates of approximately 50 m3/ha in a study site where stem volume varied between 0 and 220 m3/ha.
Coefficient extraction for MPM using LSE, ORLS and SLS applied to RF-PA modeling

Three methods for extracting the behavioral modeling coefficients of the memory polynomial model are compared herein. The first one is the ordinary least square regression, which is widely used for adjusting model parameters; the second is the order recursive least squares, which is suitable for exploring the optimal nonlinearity order and memory depth by comparing subsequent errors while increasing the complexity of the model; and the third is called sequential least square, which is very attractive to be implemented and it only requires identifying the behavior of a power amplifier, and calculating the most accurate model coefficients for each measurement. The equations of the three methods were simulated in Matlab for the NXP 10W power amplifier with complex baseband data, and their implementation was evaluated with normalized mean square error. Also a comparison of their computational complexity based on Halstead metrics is given herein.
Clinical Applications of Breathing Regulation

Breathing training is widely used as an aid in reducing anxiety states, but several other applications also show promise. This article reviews evidence that normalizing breathing patterns may offer help in some cases of essential hypertension, angina, functional chest disorder, chronic obstructive pulmonary disease (COPD), and cardiac rehabilitation. Hyperventilation and hypo-ventilation, inhibited breathing, and breath suspension are all deviations from an optimal breathing pattern in which breathing volume is closely matched to metabolic needs. Such disordered breathing has varying effects on acid/base balance, arterial diameter, and sodium retention by the kidneys. Therefore, a chronic breathing imbalance can contribute to pathophysiology, which may be remediable to an extent by altering habitual breathing patterns.
Biomechanical studies on two anterior thoracolumbar implants in cadaveric spines.

STUDY DESIGN A biomechanical comparison of two commonly used anterior spinal devices: the Smooth Rod Kaneda and the Synthes Anterior Thoracolumbar Spinal Plate. OBJECTIVES To compare the stability imparted to the human cadaveric spine by the Smooth Rod Kaneda and Synthes Anterior Spinal Plate, and to assess how well these devices withstand fatigue and uni- and bilateral facetectomy. SUMMARY OF BACKGROUND DATA Biomechanical studies on the aforementioned and similar devices have been performed using synthetic, porcine, calf, or dog spines. As of the time of this writing, studies comparing anterior spinal implants using human cadaveric spines are scarce. METHODS An L1 corpectomy was performed on 19 spines. Stabilization was accomplished by an interbody wooden graft and the application of the Smooth Rod Kaneda in 10 spines and the Synthes Anterior Spinal Plate in the remaining 9. Biomechanical testing of the spines was performed in six degrees of freedom before and after stabilization, and after fatiguing to 5000 cycles of +/- 3 Nm of flexion and extension. Testing was repeated after uni- and bilateral facetectomy. RESULTS After stabilization, the Smooth Rod Kaneda was significantly more rigid than the anterior thoracolumbar bar spinal plate in extension. After fatigue, the Smooth Rod Kaneda was significantly stiffer than the anterior thoracolumbar spinal plate in flexion, extension, right lateral bending, left lateral bending, and right axial rotation. A significant decrease in stiffness was noted with the Synthes device in flexion after bilateral facetectomy compared with the stabilized spine. CONCLUSIONS The smooth Rod Kaneda device tends to be stiffer than the anterior thoracolumbar spinal plate, particularly in extension, exceeding the anterior thoracolumbar spinal plate in fatigue tolerance. The spine stabilized with the anterior thoracolumbar spinal plate is more susceptible to the destabilizing effect of bilateral facetectomy than than that stabilized with the Smooth Rod Kaneda. The additional rigidity encountered with the Smooth Rod Kaneda must be weighed against the simplicity of anterior thoracolumbar spinal plate application.
Transcription factor access to promoter elements

In eukaryotes, transcription factors, including both gene‐specific activators and general transcription factors (GTFs), operate in a chromatin milieu. Here, we review evidence from gene‐specific and genome‐wide studies indicating that chromatin presents an environment that is typically permissive for activator binding, conditional for pre‐initiation complex (PIC) formation, and inhibitory for productive PIC assembly within coding sequences. We also discuss the role of nucleosome dynamics in facilitating access to transcription factors (TFs) in vivo and indicate some of the principal questions raised by recent findings. J. Cell.

Modeling Workflow for Study of Functional Electrical Stimulation in Peripheral Nerves

Urinary dysfunctions are among the most devastating consequences of spinal cord injuries (SCI). Neurostimulation of intact sacral nerve roots innervating bladder is potentially a good alternative to the treatments using drugs and catheterization. A finer control over the electrical stimulation of sacral roots can be an enabling technology for developing advanced neurostimulation matching the patient needs. In this paper a modeling workflow to study axon behaviour in sacral nerve roots is presented. Simulation results show that the width and the amplitude of the stimulation electric pulses can be tuned to selectively recruit axons in sacral roots. A selective recruitment of axons innervating bladder is shown to be possible for pulse
WLC42-1: Multiple-Model Rao-Blackwellized Gauss-Hermite Filter for Joint Frequency Offset and Channel Estimator for the Semi-Blind MIMO-OFDM Receiver

In this paper, we propose a new statistical joint frequency offset and channel estimation for the blind MIMO-OFDM system, where a state and parameters of dynamic systems are unknown. To reduce a channel mismatch problem, we use the fixed structure interacting multiple model (FS-IMM) and the Rao-Blackwellized Gauss-Hermite filter to estimate a model-dependent channel and offset parameter, which enters an observation function in a nonlinear manner. The resulting structure consists of M parallel bank of Kalman filters driven by sampled nonlinear state variable sequences.
El análisis transaccional como técnica de recogida de datos para el estudio del comportamiento de los usuarios del catálogo en línea

Resumen: La mayor parte de los estudios del uso de los catalogos en linea estan basados en un pequeno conjunto de metodos de investigacion que, a menudo, son adoptados de las ciencias sociales. Los dos tipos de investigaciones mas importantes son las encuestas exploratorias y el analisis transaccional. El segundo consiste en examinar el propio proceso de interrogacion y es un metodo relativamente nuevo para registrar y estudiar la conducta humana generalmente de forma no intrusiva. El analisis visual de una transaccion permite rapidamente a los investigadores ponerse ellos mismos en el lugar del usuario y comenzar a pensar como la persona que llevo a cabo la sesion de busqueda. Para algunos investigadores esta tecnica es aun mas valiosa si se compara la conducta de busqueda real y las opiniones de los usuarios recogidas en cuestionarios y encuestas sobre su conducta. La comunicacion expone las posibilidades, aplicaciones y limitaciones de esta tecnica asi como los principales resultados de los analisis transaccionales mas importantes realizados en los catalogos en linea.
Spatiotemporal analysis of urban environment based on the vegetation–impervious surface–soil model

Abstract This study explores a spatiotemporal comparative analysis of urban agglomeration, comparing the Greater Toronto and Hamilton Area (GTHA) of Canada and the city of Tianjin in China. The vegetation–impervious surface–soil (V–I–S) model is used to quantify the ecological composition of urban/peri-urban environments with multitemporal Landsat images (3 stages, 18 scenes) and LULC data from 1985 to 2005. The support vector machine algorithm and several knowledge-based methods are applied to get the V–I–S component fractions at high accuracies. The statistical results show that the urban expansion in the GTHA occurred mainly between 1985 and 1999, and only two districts revealed increasing trends for impervious surfaces for the period from 1999 to 2005. In contrast, Tianjin has been experiencing rapid urban sprawl at all stages and this has been accelerating since 1999. The urban growth patterns in the GTHA evolved from a monocentric and dispersed pattern to a polycentric and aggregated pattern, while in Tianjin it changed from monocentric to polycentric. Central Tianjin has become more centralized, while most other municipal areas have developed dispersed patterns. The GTHA also has a higher level of greenery and a more balanced ecological environment than Tianjin. These differences in the two areas may play an important role in urban planning and decision-making in developing countries.

Rapid communication: linkage and physical mapping of the porcine melanocortin-4 receptor (MC4R) gene.

Genus and Species. Sus scrofa. Locus. Pig Melanocortin-4 Receptor (MC4R) gene. Source and Description of Primers. Primers were designed from well-conserved sequence regions between the human and rat MC4R genes (Genbank accession no. S77415 and U67863, respectively). The primers were used to amplify approximately 760 bp of the porcine MC4R gene from genomic DNA. The sequence of the PCR product showed 92.2 and 97.6% identities at the nucleotide and amino acid levels, respectively, to the corresponding human sequence. The porcine MC4R sequence has been submitted to GenBank (accession no. AF087937). Using this sequence, pig-specific primers were designed.
A novel algorithm for recovering the 3D motions of multiple moving rigid objects

A number of algorithms have been developed to determine the motion of rigid objects. Most of these algorithms work on single or multiple objects with single motion. However, in the real world, multiple motions are common place. In this paper, a novel algorithm for recovering the 3D motions of multiple moving rigid objects is derived. This new approach is able to determine the total number of motions in the system and to perform 3D motion-based segmentation by using incremental clustering. Then the motion of each independent rigid object can be recovered.

Phrase database Approach to structural and semantic disambiguation in English-Korean Machine Translation

In machine translation it is common phenomenon that machine-readable dictionaries and standard parsing rules are not enough to ensure accuracy in parsing and translating English phrases into Korean language, which is revealed in misleading translation results due to consequent structural and semantic ambiguities. This paper aims to suggest a solution to structural and semantic ambiguities due to the idiomaticity and non-grammaticalness of phrases commonly used in English language by applying bilingual phrase database in English-Korean Machine Translation (EKMT). This paper firstly clarifies what the phrase unit in EKMT is based on the definition of the English phrase, secondly clarifies what kind of language unit can be the target of the phrase database for EKMT, thirdly suggests a way to build the phrase database by presenting the format of the phrase database with examples, and finally discusses briefly the method to apply this bilingual phrase database to the EKMT for structural and semantic disambiguation.
Recognition of facial expressions using locally weighted and adjusted order Pseudo Zernike Moments

Recently, various approaches to facial expression recognition have been proposed, but they do not provide a powerful approach to recognize expressions from Partially Occluded Facial Images. Moreover, they usually are global and the importance of different areas in facial images is considered equally. In this paper, we propose a novel facial expression recognition approach based on locally weighted and adjusted order Pseudo Zernike Moments (PZM). PZM is one of the best descriptors that are robust to noise and rotation. In our system, the proposed method employs a local PZM to represent faces partitioned into patches. Also, in this paper, the maximum order of PZM is adjusted based on the importance of the local areas. An extensive experimental investigation is conducted using JAFFE, FG-Net and Radboud Faces databases. The encouraging experimental results demonstrate that the proposed method has significant improvement than other methods. Moreover, our system is robust to the changes on age, ethnicity, and gender.
