The Role of Institutional Ownership and Herding in Diversification Strategy (2002)

This paper aims at exploring the relative importance of institutional ownership and behavior of herding in the effect of diversification. I first examine the degree of significance on herding for stocks with different levels of institutional ownership. Many previous studies based on the US market argue that institutional investors may exhibit more herding behavior than the individual investors since there are more incentives for the institutional investors than for the individual investors to herd in their trading. Indeed, I find that stocks with higher (lower) mutual fund ownership tend to exert higher (lower) degree of herding. But the extent of herding is not as strong for the securities dealers. This implies that mutual fund managers exhibit more herding than securities dealers do. Next, I attempt to assess the diversification benefits for the portfolios with different levels of institutional ownership or different extent of herding. The evidence shows that the return association is higher (and consequently, the diversification benefit is lower) among stocks with larger institutional ownership than those with less institutional ownership. This pattern still exists even after controlling for the factors of industry, market capitalization and value/growth stocks. This finding implies that institutional ownership plays an important role in the stock diversification effect. Finally, I find that the institutional herding itself does not affect the stock diversification.
Abnormal Water Turnover Associated with Hypothalamic Obesity* (1981)

Experimental obesity produced in rats by stereotaxic lesions of the ventromedial hypothalamus (VMH) resulted in hyperphagia, polydipsia, polyuria, decreased urine osmolality, and enhanced excretion of total solute and urea. A 24-h water deprivation test revealed the inability of VMH-lesioned rats to increase urine antidiuretic hormone (ADH) excretion. Thus, destruction of the VMH area appears to be accompanied by impairment of ADH secretion, resulting in a diabetes insipidus syndrome that is partially masked by food restriction and improved by treatment with exogenous ADH.

<title>Radio frequency interference removal in a VHF/UHF deramp SAR</title> (1995)

This paper summarizes the results of an ARPA/Army sponsored program to develop innovative approaches for reducing the effects of multiple source of radio frequency interference (RFI) on synthetic aperture radars (SARs) operating in the frequency range of 100 MHz to 1000 MHz. Since the SAR signal can be modeled as wide band noise, the approach taken to achieve the objective was to model the RFI as a collection of tones within the desired SAR signal bandwidth. RFI suppression consisted of detecting the presence of and estimating the number of these tones, estimating their amplitude, phase, and frequency, and finally reconstructing the RFI and coherently subracting it from the original corrupted signal. Central to our approach was the use of a parametric maximum likelihood (PML) algorithm for the estimation of the parameters of the RFI tones. Although most of our effort was devoted to the evaluation of the performance obtainable from the PML algorithm, a variation of band-stop filtering, which is referred to as the Notch or Adaptive Mask algorithm, was also studied. Since the focus of this program was the development of algorithms for the ultra-wideband (UWB) P-3 SAR, which is a deramp SAR, a means of applying the PML algorithm to deramped RFI was also necessary. This paper will thus briefly describe the PML algorithm and how it can be applied to a deramp SAR, and it will then discuss the preformance of both RFI suppression algorithms and their computational complexity. As a result of this one year effort, two RFI algorithms have been developed that automatically remove 90 to 95 percent of the RFI that could have corrupted a SAR image.
The novel synchronous rectifier driving method for LLC series resonant converter (2012)

This paper proposes a current driving scheme for synchronous rectifier (SR) of the LLC series resonant converter. Because the magnetizing current of transformer is included in the primary winding of transformer, it cannot be used to generate the driving signals of SRs. To cancel the magnetizing current from primary current, the magnetizing current detector circuit is used. With the proposed driving scheme, the SR body diode conduction is reduced to almost zero. Moreover, the driving scheme eliminates the reverse recovery problem of SRs. Therefore, higher efficiency can be achieved. To verify the proposed method, a 300W LLC series resonant converter prototype is made.
A Convenient Synthesis of Phosphonic Anhydrides − Trimers [RPO2]3 (R =tert-Butyl, 2-Methylphenyl, 2,4,6-Trimethylphenyl): Their Structures and Reaction Products (1998)

By reaction of RP(O)Cl2 with RP(O)(OSiMe3)2, phosphonic anhydrides (RPO2)3 (R = tBu, 2-methylphenyl, 2,4,6-trimethylphenyl) 1a−c are conveniently obtained. In contrast to 1b and 1c, compound 1a is remarkably stable against protolysis. Intermediates of hydrolysis of 1a, namely tris(tert-butyl)triphosphonic acid (2) and bis(tert-butyl)diphosphonic acid (3), can also be isolated in good yield. The structures of 1−3 were determined mainly by NMR spectroscopy (1 H, 13C, 31P). Assuming an energetic preference for the chair conformations in solution, and considering the steric requirements of the bulky substituents R, configurations Ia (point group Cs, two R in equatorial positions) for 1a and b, and IIa (point group C3v, all R equatorial) for 1c are suggested. − Reaction of 1a with N-benzyloxycarbonylglycine (4) in methanol affords strong evidence that in the first step of peptide synthesis with (RPO2)3, a mixed anhydride of triphosphonic acid and the N-protected amino acid is formed. − The crystal structure of 1a (monoclinic, space group P21/n) widely corresponds to the suggested configuration Ia, but reveals an envelope conformation for the six-membered ring with a P3O2 plane in the crystal. In the crystal structure of the octahydrate of the disodium salt of 2 (monoclinic, space group P21/c), it can be seen that the polar end groups of the anions [tBu3P3O7]2− together with the water molecules and the Na+ cations, form hydrogen-bonded double-layers, strictly separated from each other by the non-polar tert-butyl groups of the anions.
Improved GPS Positioning for Motor Vehicles Through Map Matching (1994)

Absolute positioning systems, especially the Globa l Positioning System (GPS), are playing an increasing role in the tracking of motor vehicles. Such systems, however were net designed to specifically track motor vehicles. Apart from the start and finish of journeys, motor vehicles are restricted to the mad network; a fact not reflected by the position measurements. Techniques exist for carrecting the measurements according to a map of the network but a mathematical framework for this correction process is lacking. The author has develope d such a framework resulting in a map-aided estimation process that takes into account th e measurement noise statistics to optimally translate the raw position measurements onto the road network. The theoratical performance of this estimator is derived and compared with that achieved using GPS measurements. The effect that Selective Availability (SA) has on the map-aided estimator is analysed and a technique for reducing the effect of SA i s demonstrated In addition to the accuracy improvements, th e map-aided positioning framework also provides a means for readily incorporationg other sources of positioning information. Driver bchaviour, mad type, and vehicle dynamics can be used to make further improvements in positioning accuracy and road identitication.’
Design and Application of Preschool Education System Based on Mobile Application (2022)

With the rapid development of information technology in recent years, the country’s information reform in the field of education is advancing gradually. As the first link in the chain of lifelong education, the development of early childhood education informatization has become an essential component of the national education informatization construction. In order to better realize the gamification of early childhood education courses and strengthen the management and deepening of course resources, this paper analyzes the significance of the application of children’s games in teaching and the significance of the application of new media resources in children’s course games by combining the actual situation of education and the teaching advantages of new media resources. The paper studies the application of early childhood education teaching and the research on the development of gamification in early childhood education courses. In light of the fact that emerging preschool education products on the market cannot fully meet the requirements of preschool education informatization construction at the level of function and technology, this paper proposes a preschool education system based on mobile applications as well as a child-appropriate recommendation algorithm based on a multiattention mechanism. Experiments conducted on public data sets demonstrate that our algorithm is considerably superior to the benchmark algorithm.
Exercise- and Cough-induced Asthma (1970)

A case report of a patient in which exercise and cough induced asthmatic attacks is presented. Besides exercise, maximal voluntary hyperventilation, and repeated forced expirograms yielded each time an asthmatic attack. Coughing, spontaneously or imposed, precipitated also an asthmatic attack. A high flow rate is considered to be responsible for triggering asthmatic attacks through stimulation of airway receptors.
Posttreatment Changes in <i>Escherichia coli</i> Antimicrobial Susceptibility Rates among Diarrheic Patients Treated with Ciprofloxacin (2005)

Changes in antimicrobial resistance of Escherichia coli among deployed U.S. military personnel being treated for diarrhea were evaluated. Stool samples were collected pretreatment and on days 7, 14, and 28 posttreatment. Resistance to ciprofloxacin was noted in 13.3% of baseline specimens, and rates of resistance against multiple antibiotics increased dramatically from baseline to day 7 and then tapered off to return to pretreatment levels by day 28, except for ciprofloxacin, suggesting that population accumulative usage of fluoroquinolones may result in an incremental increase in resistance rates.
Privacy-preserving <i>k</i> -means clustering over vertically partitioned data (2003)

Privacy and security concerns can prevent sharing of data, derailing data mining projects. Distributed knowledge discovery, if done correctly, can alleviate this problem. The key is to obtain valid results, while providing guarantees on the (non)disclosure of data. We present a method for k-means clustering when different sites contain different attributes for a common set of entities. Each site learns the cluster of each entity, but learns nothing about the attributes at other sites.

Evidence-based pharmacotherapy of obsessive–compulsive disorder (2005)

Obsessive-compulsive disorder is a prevalent and disabling lifespan disorder. Clomipramine and the SSRIs have been found to be effective across the range of symptoms, both in acute and longer-term studies. Meta-analyses have reported a larger treatment effect for clomipramine relative to the SSRIs, but this is not supported by evidence from head-to-head comparator studies and, based on their superior safety and tolerability, SSRIs are the preferred option for long-term treatment in most cases. The treatment-effect is usually gradual and partial, and many patients fail to respond adequately to first-line treatment. Pharmacological options for refractory cases include switching SRI, increasing the dose, or augmenting with an antipsychotic agent. Novel strategies are under investigation for this highly morbid group. This paper reviews the key questions related to OCD pharmacotherapy, synthesizing evidence derived from randomized controlled trials, meta-analyses and consensus guidelines.
Table of Contents (2010)

This study evaluates the characteristics of the men who served in the volunteer military in combat occupations. It examines whether these characteristics stem from supply-side or demand-side decisions, or reflect class bias. The findings suggest that, on the supply side, men who had greater academic abilities were more likely to go to college, thereby avoiding military service and the possibility of serving in a combat occupation. On the demand side, the armed forces were more likely to exclude men with lower academic abilities but were more likely to assign such men in the military to combat occupations. Net of the impacts of these supply-side and demand-side decisions, men who served in combat occupations still differed from those who did not in terms of their family background. The impact of family background was stronger on entering the military than on being assigned to combat occupations once in the military.
A forward-viewing intravascular ultrasound catheter suitable for intracoronary use. (1997)

Current intravascular ultrasound (IVUS) catheters provide a transverse cross-sectional view of the blood vessel, thus limiting their ability to visualize severely stenosed or occluded vessels. Forward-viewing IVUS devices can overcome these limitations. Previously described forward-viewing IVUS catheters are mechanically complex, making them too bulky for use in coronary arteries. A new design for small-forward viewing IVUS catheters was developed. Using this design, flexible 5-Fr (1.6 mm diameter) and 8-Fr (2.6 mm diameter) prototype catheters up to 110 cm long, suitable for intravascular work, were constructed. Imaging of cadaver arterial segments was performed using these prototype catheters. Structures such as branches and plaque and features such as calcium were well seen with these catheters. Correlation of lumen dimensions measured with the IVUS catheters and by histology (HIST) was excellent: IVUS = 1.06 x HIST - 1.45 mm, r2 = 0.98. This new technology holds promise as a tool for guiding intravascular interventions.

IMPES Stability: Selection of Stable Timesteps (2003)

Summary An IMPES stability criterion is derived for multidimensional three-phase flow for black-oil and compositional models. The grid may be structured or unstructured. Tensor considerations are neglected. The criterion can be used to set the time steps in an IMPES formulation or as a switching criterion in an adaptive implicit model. The criterion extends previous work by accounting for three-phase flow, including capillary, gravity, and viscous forces, with all the possible cocurrent and countercurrent flow configurations in a general grid. The criterion derivation uses stability theory to the limits of its applicability, augmented by numerical experimentation, including extensive 1D tests and numerous field study datasets.

Videostroboscopy of Human Vocal Fold Paralysis (1992)

Previous stroboscopic studies of human vocal cord paralysis have been infrequent and have lacked documentation of the site of lesion. In order to study human laryngeal paralysis, the recurrent and superior laryngeal nerves were infiltrated unilaterally with lidocaine hydrochloride in three human volunteers. Vagal paralysis was simulated by combined (superior and recurrent) infiltration in one volunteer. Additionally, 20 patients with untreated laryngeal paralysis were studied from the voice laboratory at UCLA. In addition to videostroboscopic analysis, photoglottography and electroglottography were performed and synchronized with the stroboscopic images. The most significant finding in stroboscopy of the paralyzed larynx was the asymmetry of traveling wave motion. The traveling wave on the normal vocal fold had a faster wave velocity that created a phase difference in the vibration of the two folds. The wave also traversed a greater distance along the vocal fold mucosa on the normal side. No patient or volunteer with untreated laryngeal paralysis had a symmetric traveling wave, either in superior or recurrent laryngeal nerve paralysis. Synchronization with glottography indicated that the differentiated electroglottographic waveform provides useful information about the timing of glottic opening and closure in states of asymmetric laryngeal vibration. Implications for future studies and for the diagnosis of laryngeal paralysis are discussed.

Smurf2 Is a Ubiquitin E3 Ligase Mediating Proteasome-dependent Degradation of Smad2 in Transforming Growth Factor-β Signaling (2000)

Smads are important intracellular signaling effectors for transforming growth factor-beta (TGF-beta) and related factors. Proper TGF-beta signaling requires precise control of Smad functions. In this study, we have identified a novel HECT class ubiquitin E3 ligase, designated Smurf2, that negatively regulates Smad2 signaling. In both yeast two-hybrid and in vitro binding assays, we found that Smurf2 could interact with receptor-activated Smads (R-Smads), including Smad1, Smad2, and Smad3 but not Smad4. Ectopic expression of Smurf2 was sufficient to reduce the steady-state levels of Smad1 and Smad2 but not Smad3 or Smad4. Significantly, Smurf2 displayed preference to Smad2 as its target for degradation. Furthermore, Smurf2 exhibited higher binding affinity to activated Smad2 upon TGF-beta stimulation. The ability of Smurf2 to promote Smad2 destruction required the HECT catalytic activity of Smurf2 and depended on the proteasome-dependent pathway. Consistent with these results, Smurf2 potently reduced the transcriptional activity of Smad2. These data suggest that a ubiquitin/proteasome-dependent mechanism is important for proper regulation of TGF-beta signaling.
High Capacity Data Hiding for Binary Image Authentication (2010)

This paper proposes a novel data hiding scheme with high capacity for binary images, including document images, halftone images, scanned figures, text and signatures. In our scheme, the embedding efficiency and the placement of embedding changes are considered simultaneously. Given an M×N image block, the upper bound of the amount of bits that can be embedded of the scheme is nlog <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ((M×N)/n + 1) by changing at most n pixels. Experimental results show that the proposed scheme can embed more data, meanwhile maintain a better quality, and have wider applications than existing schemes.
Preparation and characterization of microcapsule containing epoxy resin and its self-healing performance of anticorrosion covering material (2011)

Microencapsulated healing agents that possess adequate strength, long shelf-life, and excellent bonding to the host material are required for self-healing materials. The in situ encapsulation method is demonstrated over an order of magnitude size reduction for the preparation of urea-formaldehyde (UF) capsules filled with a healing agent, a mixture epoxy resin of the epoxy 711 and E-51. Capsules with diameters as small as about 100 μm are achieved under the agitation rate of 800 r min−1. The capsules possess a uniform UF shell wall (4 μm average thickness). By using the analysis of scanning electronic microscope (SEM), thermal analysis (TG-DTA) and FTIR, the characteristics of the microcapsules were investigated respectively. Successful self-healing has been demonstrated for anticorrosion covering materials with microcapsules.

Protection against generalized autoimmunity of the nervous system (GANS), a novel animal model with combined features of EAE, EAN and EAU by a recombinant HIV-1 Tat<sub>37–72</sub>peptide-based multiple T cell epitope vaccine (1997)

A new model of multi-compartment auto-immune disease has been established to analyze the effects of polyvalent recombinant peptide vaccines. A synthetic gene encoding major pathogenic determinants for Lewis rats of guinea pig myelin basic protein (MBP68-84), bovine interphotoreceptor retinoid binding protein (IRBP1169-1191), and bovine P2 protein (P2,53-78) was used to induce Generalized Autoimmunity of the Nervous System (GANS), which is characterized by development of auto-immune infiltration of the brain and spinal cord, the eyes, the pineal organ and the peripheral nerves. Thus, this model integrates the prominent features of three auto-immune diseases: experimental autoimmune encephalomyelitis (EAE), neuritis (EAN) and uveitis (EAU). In this study, GANS was used to study the effect of HIV-1 Tat37-72 targeting peptide on vaccination by recombinant polyvalent T cell auto-antigen vaccine. Depending on the route of administration, the recombinant vaccine effectively protects against the development of auto-immune nervous system inflammation.
