9.3 A 40kHz-BW 90dB-SNDR Noise-Shaping SAR with 4× Passive Gain and 2<sup>nd</sup>-Order Mismatch Error Shaping (2020)

Noise-shaping (NS) SAR ADCs using passive loop filters have drawn increasing attention due to their simplicity, low power, zero static current, and PVT robustness. However, prior works show limited resolution (ENOB≤13b) due to two main challenges. The 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> one is thermal noise. Passive loop filters cannot provide gain [1]. Hence, their suppression of the comparator noise is limited. In addition, every capacitor switching introduces extra kT/C noise. To reduce noise, a passive gain of 2 is realized in [2]. It also realizes passive voltage summation, which obviates the need for a multipath comparator, further reducing the comparator noise. Nevertheless, it uses small capacitors for residue sampling to minimize signal attenuation, leading to a large total kT/C noise of 20kT/C (C is the DAC size). Also, its NTF is mild (zero at 0.5), leading to limited SQNR benefit. The 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup> challenge is DAC mismatch. Classic DEM is unsuitable for SARs with a high-resolution DAC due to excessive hardware cost. To reduce circuit complexity, Ref. [3] applies DEM only to the MSB part of the DAC, but the LSB part still produces considerable errors. The mismatch error shaping (MES) technique of [4] is well suited for high-resolution binary DACs due to low hardware complexity, but it has its own limitations. First, it can only achieve 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> -order shaping with limited error suppression capability. Also, being 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> -order, it has strong signal dependence and can produce considerable tones, especially at low input amplitudes. In addition, it suffers from signal range loss.
Sidelobe reduction in array-pattern synthesis using genetic algorithm (1997)

A simple and flexible genetic algorithm (GA) for pattern synthesis of antenna array with arbitrary geometric configuration is presented. Unlike conventional GA using binary coding and binary crossover, this approach directly represents the array excitation weighting vectors as complex number chromosomes and uses decimal linear crossover without a crossover site. Compared with conventional GAs, this approach has a few advantages: giving a clearer and simpler representation of the problem, simplifying chromosome construction, and totally avoiding binary encoding and decoding so as to simplify software programming and to reduce CPU time. This method also allows us to impose constraints on phases and magnitudes of complex excitation coefficients for preferable implementation in practice using digital phase shifters and digital attenuators. Successful applications show that the approach can be used as a general tool for pattern synthesis of arbitrary arrays.
MOTIVACIÓN DEL ACTO ADMINISTRATIVO Y BUENA ADMINISTRACIÓN (2013)

En 1978 publiqué una breve nota de jurisprudencia sobre la motivación del acto administrativo.Fue el primer trabajo doctrinario escrito en Uruguay en que se sostuvo y fundamentó el deber de la Administración de motivar sus decisiones como principio. Lo escribí con mi más profunda convicción, aunque con no poca preocupación porque al hacerlo me levanté contra la opinión dominante en nuestro medio representada por SAYAGUÉS LASO y CASSINELLI MUÑOZ, así como contra la, en ese entonces, jurisprudencia administrativa francesa, que tanto influyó en la construcción del derecho administrativo. Poco tiempo después REALescribió un enjundioso estudio sobre el tema, en el mismo sentido que el mío, pero con mayor penetración, que me permitió asentar y precisar mis ideas.
Kaposi's Sarcoma-Associated Herpesvirus K7 Induces Viral G Protein-Coupled Receptor Degradation and Reduces Its Tumorigenicity (2008)

The Kaposi's sarcoma-associated herpesvirus (KSHV) genome encodes a G protein-coupled receptor (vGPCR). vGPCR is a ligand-independent, constitutively active signaling molecule that promotes cell growth and proliferation; however, it is not clear how vGPCR is negatively regulated. We report here that the KSHV K7 small membrane protein interacts with vGPCR and induces its degradation, thereby dampening vGPCR signaling. K7 interaction with vGPCR is readily detected in transiently transfected human cells. Mutational analyses reveal that the K7 transmembrane domain is necessary and sufficient for this interaction. Biochemical and confocal microscopy studies indicate that K7 retains vGPCR in the endoplasmic reticulum (ER) and induces vGPCR proteasomeal degradation. Indeed, the knockdown of K7 by shRNA-mediated silencing increases vGPCR protein expression in BCBL-1 cells that are induced for KSHV lytic replication. Interestingly, K7 expression significantly reduces vGPCR tumorigenicity in nude mice. These findings define a viral factor that negatively regulates vGPCR protein expression and reveal a post-translational event that modulates GPCR-dependent transformation and tumorigenicity.
Enhancement of delayed skin hypersensitivity by neuraminidase in cancer patients. (1974)

Delayed skin hypersensitivity to specific antigen was enhanced when the antigen was given intradermally with Vibrio cholerae neuraminidase in sensitive subjects. No enhancement of skin test response was seen when inactivated enzyme was used. Neuraminidase exhibited no effect on negative skin-test response in non-sensitive recipients and no reaction at the site of this enzyme was observed in any instance, suggesting that the enhancement effect is immunological in nature.
Human identification using KnuckleCodes (2009)

The usage of finger knuckle images for personal identification has shown promising results and generated lot of interest in biometrics. In this work, we investigate a new approach for efficient and effective personal identification using KnuckleCodes. The enhanced knuckle images are employed to generate KnuckleCodes using localized Radon transform that can efficiently characterize random curved lines and creases. The similarity between two KnuckleCodes is computed from the minimum matching distance that can account for the variations resulting from translation and positioning of fingers. The feasibility of the proposed approach is investigated on the finger knuckle database from 158 subjects. The experimental results, i.e., equal error rate of 1.08% and rank one recognition rate of 98.6%, suggest the utility of the proposed approach for online human identification.
Event-Based User Classification in Weibo Media (2014)

Weibo media, known as the real-time microblogging services, has attracted massive attention and support from social network users. Weibo platform offers an opportunity for people to access information and changes the way people acquire and disseminate information significantly. Meanwhile, it enables people to respond to the social events in a more convenient way. Much of the information in Weibo media is related to some events. Users who post different contents, and exert different behavior or attitude may lead to different contribution to the specific event. Therefore, classifying the large amount of uncategorized social circles generated in Weibo media automatically from the perspective of events has been a promising task. Under this circumstance, in order to effectively organize and manage the huge amounts of users, thereby further managing their contents, we address the task of user classification in a more granular, event-based approach in this paper. By analyzing real data collected from Sina Weibo, we investigate the Weibo properties and utilize both content information and social network information to classify the numerous users into four primary groups: celebrities, organizations/media accounts, grassroots stars, and ordinary individuals. The experiments results show that our method identifies the user categories accurately.

Major psychiatric disorders in suicide and suicide attempters (2009)

Abstract Suicidal behaviour is closely connected with mental disorders. Virtually all mental disorders carry an increased risk of suicidal ideation, suicide attempt, and suicide. Psychiatric disorder may be an almost necessary, yet insufficient, risk factor for suicide. About 90 per cent of individuals who attempt or commit suicide meet diagnostic criteria for a psychiatric disorder, most often mood disorder, substance use disorders, psychoses, and personality disorders. The risk of suicidal behaviour in anxiety disorders and eating disorders, both having strong comorbidity with depression, is often underestimated. Under-treatment, comorbidity, treatment non-compliance and poor adherence, as well as a high frequency of non-responders are common problems and challenges in the treatment of suicidal persons. On the other hand, there is growing evidence of lower risk of suicidal behaviour during closely monitored long-term treatment of suicidal patients, indicating that treatment adherence is an important factor in medical suicide prevention.
Wireless communications and networking: an overview (2002)

This paper presents an overview of wireless local-area networks (LANs) and wireless personal area networks (PANS), with emphasis on the two most popular standards: IEEE 802.11, and Bluetooth. While there are many such surveys in the current literature and online, we attempt here to present wireless LANs and PANS in a unified fashion as a viable alternative to wired LANs, while stressing the remaining challenges and limitations.
Nurse Work Environments and Occupational Safety in Intensive Care Units (2006)

Using data collected from 39 intensive care units (ICUs) in 23 hospitals across the United States, the purpose of this study was to examine hospital structural characteristics, nurse characteristics, and nurses' working conditions' impact on occupational safety outcomes. ICU with more positive organizational climates had lower rates of occupational injuries and blood and body fluid exposures (p < .05). Similarly, ICUs in hospitals that had attained magnet accreditation had lower rates of negative occupational health incidents (p < .05). Hospital profitability was inversely related to rates of blood and body fluid exposure (p < .05). Monitoring nurses' working conditions and improving the organizational climate of hospitals is likely to improve the safety of the employee and the profitability of the hospital through improved system outcomes (such as lower turnover of the employees) as well as improve the quality of patient care delivered.
Temperature dependence of positronium decay rates in gases (2000)

The decay rate of orthopositronium (o-Ps) formed and thermalized in eight different gases is systematically investigated as a function of temperature. The o-Ps collisional quenching rate is observed to increase with temperature, T , for He, Ne, Ar, N 2 , ethane, methane, isobutane and neopentane. All of the gases except ethane and methane increase linearly over the investigated temperature range, 300 K < T < 600 K. Recent theoretical work for noble gases at elevated temperatures suggests a linear increase in the collisional quenching rate with temperature at the low densities used herein where collective phenomena such as bubble formation and density fluctuations are not present. When comparisons can be made with previous experimental results the agreement is generally poor. Precision o-Ps decay rate measurements using gases are also discussed concerning systematic effects due to the energy dependence of the collisional quenching rate.
An Improved Variable Step-Size LMS Algorithm (2011)

To improve the performance of LMS adaptive algorithm, in this paper a new variable step-size LMS algorithm is proposed based on the analysis of some variable step-size algorithms. Through establishing a new nonlinear relationship between the step size and the error, the algorithm eliminates the irrelevant noise and improves the convergence rate to obtain a better stability. And the computer simulation results are consistent with the theoretical analysis, which confirmed that the algorithm is superior to other algorithms on convergence rate, tracking speed and steady-state error.
Study on the Risk Factors of Flare in Systemic Lupus Erythematosus (2003)

Objective To investigate the risk factors of flare in systemic lupus erythematosus(SLE).Methods In this retrospective cohort study132cases of SLE were followed up for1～5years.The risk factors of SLE flare were analyzed by univariate and multivariate logistic regression with computer software,SPSS.Results Of the132patients,82cases had more than one flare,the total number of flares was115.The incidence of flare was0.22per patient-year.The frequency of flares within5years after diagnosis of SLE was higher than that in more than5years.By univariate logistic regression analysis the age younger than40years at the beginning of the study,age of disease onset younger than32years,stress,depression,overwork,pregnancy,suffering from infectious disease,and quick decreasing of prednisone dosage significantly increased the risk of flare(P0.05),while menopause,regular follow up,and receiving maintenance dose of prednisone therapy decreased the risk of flare.By multivariate logistic regression analysis the quick decreasing of prednisone dosage(OR=6.85),younger age of onset of the disease(OR=5.03),infectious disease(OR=4.24),overwork(OR=3.41),stress(OR=2.70)were independent risk factors for SLE flare(P0.05),while menopause(OR=0.14)decreased the risk of SLE flare(P0.05).Conclusions The quick decreasing of prednisone dosage,younger age of disease onset,infectious disease,overwork,stress were important risk factors for SLE flare.The SLE patients should be advised to avoid these risk factors in order to prevent from disease flare.

A low-light image enhancement method for both denoising and contrast enlarging (2015)

In this paper, a novel united low-light image enhancement framework for both contrast enhancement and denoising is proposed. First, the low-light image is segmented into superpixels, and the ratio between the local standard deviation and the local gradients is utilized to estimate the noise-texture level of each superpixel. Then the image is inverted to be processed in the following steps. Based on the noise-texture level, a smooth base layer is adaptively extracted by the BM3D filter, and another detail layer is extracted by the first order differential of the inverted image and smoothed with the structural filter. These two layers are adaptively combined to get a noise-free and detail-preserved image. At last, an adaptive enhancement parameter is adopt into the dark channel prior dehazing process to enlarge contrast and prevent over/under enhancement. Experimental results demonstrate that our proposed method outperforms traditional methods in both subjective and objective assessments.
The Effect of Ellagic Acid on Coagulation in Vivo (1966)

Abstract Ellagic acid shortens the silicone and glass clotting times of the blood of dogs, cats, rabbits and rats. The silicone clotting time is reduced so as to make it almost equal to the normal glass clotting time for 5 to 30 minutes after the injection of the agent. There is occasional acceleration of thromboplastin generation in dogs. No other clotting factors were altered significantly in our experiments. There were no obvious toxic effects of ellagic acid, and it appears to decrease bleeding in normal animals.
A comparison of three methods of extracting resonance information from predictor-coefficient coded speech (1976)

Three methods of extracting resonance information from predictor-coefficient coded speech are compared. The methods are finding roots of the polynomial in the denominator of the transfer function using Newton iteration, picking peaks in the spectrum of the transfer function, and picking peaks in the negative of the second derivative of the spectrum. A relationship was found between the bandwidth of a resonance and the magnitude of the second derivative peak. Data, accumulated from a total of about two minutes of running speech from both female and male talkers, are presented illustrating the relative effectiveness of each method in locating resonances. The second-derivative method was shown to locate about 98 percent of the significant resonances while the simple peak-picking method located about 85 percent.

The Effects of Local and Intravenous Anesthetics on Recombinant Rat VR1 Vanilloid Receptors (2003)

Vanilloid receptors (VR1) are activated by capsaicin, the pain-producing component of hot chili peppers. We suggest that local (but not IV general) anesthetics may have inhibitory actions on this receptor.
Sparse 2-D Canonical Correlation Analysis via Low Rank Matrix Approximation for Feature Extraction (2011)

Although 2-D canonical correlation analysis (2DCCA) has been proposed to reduce the computational complexity while reserving local data structure of image, the learned canonical variables of 2DCCA are the linear combination of all the original variables, which makes it hard to interpret the solutions and might have less generality. In this paper, we propose a sparse 2-D canonical correlation analysis (S2DCCA) to solve the drawbacks of the 2DCCA method and apply it to image feature extraction. The basic idea of S2DCCA is to impose two lasso penalties on the objective function of 2DCCA to obtain two sets of sparse projection directions via low rank matrix approximation. We conduct extensive experiments on both FERET and AR databases to evaluate the performance of the proposed method.
Carbodiimide-mediated cross-linking of RNA to nylon membranes improves the detection of siRNA, miRNA and piRNA by northern blot (2007)

The northern blot, or RNA gel blot, is a widely used method for the discovery, validation and expression analysis of small regulatory RNA such as small interfering RNA (siRNA), microRNA (miRNA) and piwi-interacting RNA (piRNA). Although it is straightforward and quantitative, the main disadvantage of a northern blot is that it detects such RNA less sensitively than most other approaches. We found that the standard dose of UV used in northern blots was not the most efficient at immobilizing small RNA of 20-40 nt on nylon membranes. However, increasing the dose of UV reduced the detection of miRNA by hybridization in northern blotting experiments. We discovered that using the soluble carbodiimide, EDC, to cross-link RNA to nylon membranes greatly improved the detection of small RNA by hybridization. Compared to standard UV cross-linking procedures, EDC cross-linking provided a 25-50-fold increase in the sensitivity of detection of siRNA from plants and miRNA or piRNA from mammalian cells. All types of hybridization probes tested benefited from the new cross-linking procedure. Cross-linking was dependent on a terminal phosphate and so, should be applicable to other related categories of small RNA.
Mobile robot localization using an electronic compass for corridor environment (2002)

This paper proposes a simple method for localization using an electronic compass. Electronic compasses are often used to detect the heading of mobile robots. However, electronic compasses have one drawback when used inside a building: they can easily be disturbed by electromagnetic sources (e.g., power lines) or large ferro-magnetic structures (e.g., bookshelves). However, this paper introduces another indoor application of electronic compasses. We take advantage of the magnetic field disturbances by using them as distinctive place recognition signatures. We first gather information about the changing heading as our robot travels along the hallway outside the lab, and then store this information. As the robot traverses the hallway, it gathers the information from the electronic compass and matches it with the pre-stored data. If a match is found, the robot can determine its current position. We use a sequential least-squares approximation approach for matching the signature. The simulation results will show that the robot can distinguish its location by using these signatures.
Pattern recognition with parallel associative memory (1990)

Recognizing specific patterns plays an important role in digital photogrammetry. A common task is locating special targets in an image, such as control points. The paper explores the applicability of Parallel Associative Memory (PAM) for searching targets in aerial photographs. The PAM we used in our research is based on the Nearest-Neighbor algorithm and uses the Hamming distance as a measure of closeness to discriminate patterns. This approach is particularly successful if the patterns can be described logically. Our research focused on targets typically used for ground control points. We tried to develop a method which parallel to the data acquisition process sorts out the approximate target positions where the precise localizations are needed. A library with different targets was entered into the PAM. Image patches that were moved across the image were constantly compared with the library by determining the Hamming distance. The results are encouraging. The majority of control points in different images were correctly identified and only a few targets were wrongly matched.
