Base station and service social network and its application in cellular networks (2017)

With the rapid development of wireless networks, the fourth-generation (4G) communication network is becoming increasingly popular and the fifth-generation (5G) network is expected to be commercialized by 2020. Many types of new services are being gradually applied mobile terminals with increasingly complex data in terms of diversity, scale, and dimension. It has become a popular research topic to optimize the base station deployment as well as resource scheduling strategy to meet various service requirements based on the cognizing of cellular network service pattern. We introduce a social network analysis method and propose a novel method to build service social network and base station social network (BSSN) for typical wireless network based on a study of wireless big data in practical networks. Additionally, traffic fluctuations can be predicted based on selected several typical very important base stations (VIBS), and caching strategies for cellular network can be optimized based on BSSN. This work provides insights and possible solutions for traffic monitoring, congestion prevention, network deployment and optimization, as well as resource scheduling optimization based on the characteristics of big data in cellular network.
Optimal nonlinear design of marine borehole seismic surveys (2013)

ABSTRACT We explore DN-optimization, a recently introduced method in optimal experimental design theory, as a tool to minimize the forecasted postinversion model uncertainty in marine borehole seismic applications. The DN-criterion is a design objective function crafted specifically for nonlinear data-model relationships and, when used in conjunction with greedy, sequential optimization algorithms, is among the first of its kind to be computationally efficient enough for industrial-scale applications. The benefits and disadvantages of greedy algorithms are briefly discussed, and one of the most popular, the Construction algorithm, is confirmed to take (nearly) linear time, as predicted by theory. The DN-criterion is rederived here to show that restrictive assumptions in its original derivation were unnecessary. This new derivation is cast in terms of expected likelihood ratios, which quantify the discriminability of geomodels constrained by observed seismic data. A 3D vertical seismic profiling (VSP) survey and a walkaway VSP survey are DN-optimized for a site in the Gulf of Mexico, from which several potential applications are identified, including: (1) prescribing the maximum radius of 3D VSP spirals; (2) a novel annular-spiral 3D VSP geometry to reduce acquisition time and cost; (3) a novel azimuthal-walkaway geometry for presurvey acquisition; (4) identifying optimal data for rapid postacquisition quality control and quick-look inversion; (5) optimizing data decimation to facilitate the analysis of massive data sets which cannot be practically analyzed in toto; and (6) optimizing source vessel placement for offset/azimuth checkshots.
NMR structure of the principal neutralizing determinant of HIV-1 displayed in filamentous bacteriophage coat protein (1997)

An NMR approach for structure determination of short peptides displayed on the surface of filamentous bacteriophage virions is demonstrated using the hexapeptide GPGRAF that constitutes the principal neutralizing determinant of HIV-1. This peptide was inserted near the N terminus of the major coat protein of bacteriophage fd. NMR studies of the recombinant protein solubilized in detergent micelles showed that the inserted peptide adopts a double bend S-shaped conformation that is similar to the antibody-bound structure determined by X-ray crystallography. This indicates that a peptide displayed on the bacteriophage coat protein has an enhanced propensity to adopt a conformation similar to that found in the native protein from which it is derived. This approach may be generally applicable to the structure determination of peptide epitopes and other small peptides.
A Universal Microprocessor Controlled Heart Rhythm Control System (2005)

In this paper, we present the theoretical basis for a microprocessor controlled heart rhythm control system. In this system, we integrate biosensors with electrical signals derived from the heart or circulatory system. This information is processed by a microprocessor to select the appropriate timing and treatment to control the rhythm disturbance. These treatments include antibradycardia pacing, antitachycardia pacing, cardioversion, and/or defibrillation.
Remote Sensing Information Processing (2007)

Abstract One unique feature in the remote sensing problems is that a significant amount of data are available, from which desired information must be extracted. Progress in computer science and engineering has contributed significantly to the major advances on information processing in remote sensing. Areas of information processing include, but are not limited to, image processing and segmentation, pattern recognition and neural networks, knoweldge‐based method and data or information fusion, image compression, image mining, and so on. Many of the techniques can be lumped into the topic of transform method or component analysis In this article, we will provide an overview of the topics listed above and then some discussion of the independent component analysis along with some computer results.
Temporary-tattoo for long-term high fidelity biopotential recordings (2016)

Electromyography is a non-invasive method widely used to map muscle activation. For decades, it was commonly accepted that dry metallic electrodes establish poor electrode-skin contact, making them impractical for skin electromyography applications. Gelled electrodes are therefore the standard in electromyography with their use confined, almost entirely, to laboratory settings. Here we present novel dry electrodes, exhibiting outstanding electromyography recording along with excellent user comfort. The electrodes were realized using screen-printing of carbon ink on a soft support. The conformity of the electrodes helps establish direct contact with the skin, making the use of a gel superfluous. Plasma polymerized 3,4-ethylenedioxythiophene was used to enhance the impedance of the electrodes. Cyclic voltammetry measurements revealed an increase in electrode capacitance by a factor of up to 100 in wet conditions. Impedance measurements show a reduction factor of 10 in electrode impedance on human skin. The suitability of the electrodes for long-term electromyography recordings from the hand and from the face is demonstrated. The presented electrodes are ideally-suited for many applications, such as brain-machine interfacing, muscle diagnostics, post-injury rehabilitation, and gaming.
Closed-Loop Fluid Resuscitation (2013)

The results indicate that the controller is highly effective in targeting optimal blood and stroke volumes, regardless of weight, contractility or starting blood volume.
Glycosaminoglycans are involved in bacterial adherence to lung cells (2017)

Taken together, these data demonstrate that the GAG chains of the cell surface are involved in the adhesion of bacterial adhesins to lung cells. Heparan sulfate seems to be the main species implicated, and binding is dependent on the sulfation pattern of the molecule. These data could facilitate the development of new anti-infective strategies, enabling the development of new procedures for blocking the interaction between pathogens and lung cells more effectively.
p62/SQSTM1, a Central but Unexploited Target: Advances in Its Physiological/Pathogenic Functions and Small Molecular Modulators (2020)

p62/SQSTM1, encoded by gene <i>SQSTM1</i>, is widely known as an adaptor protein of selective autophagy to promote aggregate-prone proteins for degradation. It is also a stress-induced scaffold protein involved in Nrf2 activation to resist oxidative stress. Multiple domains of p62 interact with several essential pathways implicated in cell differentiation and proliferation, placing p62 at a significant position to mediate cell survival and apoptosis. The p62 protein has been suggested as a potential target in recent years, since its abnormal expression or <i>SQSTM1</i> gene mutation is tightly associated with various diseases including cancer such as hepatocellular carcinoma and prostate cancer, neurodegenerative disorders such as Alzheimer's disease and amyotrophic lateral sclerosis, atherosclerosis, and Paget's disease of bone. In this review, we will discuss the relationship between p62 and these diseases, and we attempt to put forward novel methods for current diagnosis or therapy by regulating the p62 expression level.
Dancing the numinous: sacred and spiritual techniques of contemporary American belly dancers. (2012)

In this paper, I explore how contemporary American practitioners of belly dance (as Middle Eastern dance and its many varieties are often called in the English-speaking world) conceptualize not only the spiritual dimensions of their dance, but also how the very notion of performance affects sacred and spiritual dance practices. Drawing on interviews with this community, I describe the techniques of sacred and spiritual belly dancers, how these dancers theorize performance, and how the conflicts inherent to patriarchal mind-body dualism are resolved in these practices. My purpose here is twofold: to document an emergent dance tradition and to analyze its meanings in the relevant social context.
Vascular Cell Apoptosis (1999)

These findings suggest that the effect of cytokines such as TGF-beta1 on cell fate is contextual and is modulated by cell-matrix interactions in a cell type-specific manner.
Land administration and rural development : two cases from Thailand (1999)

Experience in Thailand sheds light on one of the key dimensions of land administration: its contribution to improving natural resource management and reducing rural poverty. The two projects under review were separate and discrete interventions that were not part of an overall strategy for rural development: jon their own terms, one failed and the other succeeded. Both could have been more effective if they had been based on a broader dialogue. However, when these projects were designed--before the financial crisis of 1997--the government of Thailand was not interested in a broad program of Bank assistance. Lessons from these projects confirm that poverty reduction and natural resource management objectives can best be achieved through projects that are, indeed, part of a broader strategy for rural development.
Long-range order and short-range order study on CoCrPt/Ti films by synchrotron x-ray scattering and extended x-ray absorption fine structure spectroscopy (2002)

The long-range order (LRO) and short-range order (SRO) of CoCrPt/Ti/NiP perpendicular media films were studied by synchrotron x-ray scattering and extended x-ray absorption fine structure (EXAFS) spectroscopy in order to correlate their effects with the magnetic properties. The thickness of the magnetic media films and the NiP seed layers were kept constant, whereas the Ti underlayer thickness was varied. The increase of out-of-plane coercivity and squareness was related to the increase in the crystallinity and texture of CoCrPt (002), which first increased and then decreased with increasing Ti thickness. The best magnetic properties were observed for the magnetic film grown on the 30 nm Ti underlayer. The improvement was associated with the local atomic environment in which a relatively ordered Co, and disordered Cr and Pt existed. This suggests that a higher degree of Co and Cr phase segregation contributed to the enhancement of the magnetic properties. The LRO and SRO results are consistent with the magnetic properties.
Core Competencies for Cardiac Rehabilitation/Secondary Prevention Professionals (2011)

Cardiac rehabilitation/secondary prevention (CR/SP) services are typically delivered by a multidisciplinary team of health care professionals. The American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR) recognizes that to provide high-quality services, it is important for these health care professionals to possess certain core competencies. This update to the previous statement identifies 10 areas of core competencies for CR/SP health care professionals and identifies specific knowledge and skills for each core competency. These core competency areas are consistent with the current list of core components for CR/SP programs published by the AACVPR and the American Heart Association and include comprehensive cardiovascular patient assessment; management of blood pressure, lipids, diabetes, tobacco cessation, weight, and psychological issues; exercise training; and counseling for psychosocial, nutritional, and physical activity issues.
Proton MR Spectroscopy of the Brain in AIDS Dementia Complex (1992)

Proton MR spectroscopy of the brain has been undertaken in 8 healthy volunteers and in 11 patients with human immunodeficiency virus infection and varying stages of AIDS dementia complex (ADC). Spectral appearances in patients with no ADC or early ADC were not significantly different from normal volunteers. Spectra from patients with moderate to severe ADC exhibited significant reductions in levels of N-acetyl aspartate (NAA) relative to creatine (Cr) and also showed elevations in choline containing compounds (relative to Cr). Because NAA is though to be a metabolic marker for normally functioning neurons, these findings suggest the presence of neuronal injury or loss in moderate to severe ADC. The significance of these findings is discussed.
The Effects of Food Color on Perceived Flavor (2000)

This research investigates the role that food color plays in conferring identity, meaning and liking to those foods and beverages that assume many flavor varieties. In a taste test experiment manipulating food color and label information, 389 undergraduates at a public university (53% male and 47% female; 79% between 18 and 21 years of age) were assigned the task of evaluating a successful brand of powdered fruit drink. Results from this study indicate that food color affects the consumer’s ability to correctly identify flavor, to form distinct flavor profiles and preferences, and dominates other flavor information sources, including labeling and taste. Strategic alternatives for the effective deployment of food color for promotional purposes at the point of purchase are recommended.
Lycium barbarum polysaccharides protected human retinal pigment epithelial cells against oxidative stressinduced apoptosis (2015)

AIM: To investigate the protective effect and its mechanism of lycium barbarum polysaccharides(LBP)against oxidative stress-induced apoptosis in human retinal pigment epithelial cells.METHODS: ARPE-19 cells, a human retinal pigment epithelial cell lines, were exposed to different concentrations of H2O2 for 24h, then cell viability was measured by Cell Counting Kit-8(CCK-8) assay to get the properly concentration of H2O2 which can induce half apoptosis of APRE-19. With different concentrations of LBP pretreatment, the ARPE-19 cells were then exposed to appropriate concentration of H2O2, cell apoptosis was detected by flow cytometric analysis. Expression levels of Bcl-2 and Bax were measured by real time quantitative polymerase chain reaction(RT-PCR) technique.RSULTS: LBP significantly reduced the H2O2-induced ARPE-19 cells’ apoptosis. LBP inhibited the H2O2-induced down-regulation of Bcl-2 and up-regulation of Bax.CONCLUSION: LBP could protect ARPE-19 cells from H2O2-induced apoptosis. The Bcl-2 family had relationship with the protective effects of LBP.
The molecular biology of histochemical staining by cationic phthalocyanin dyes: the design of replacements for Alcian Blue (1980)

Four cationic copper phthalocyanin dyes are compared with Alcian Blue 8G for specificity of interaction with a range of natural and synthetic polyanions. The CEC system is used to estimate dye-substrate affinities. The results support the hypothesis that the tissue staining pattern of Alcian Blue is determined by (a) exclusion of the dye from polynucleotide stacked base pairs by steric hindrance due to bulky substituents on the chromophore and (b) the presence of pendant quaternary charges whose affinity for negative sites on polyanionic substrates is without regard for the precise chemical nature of the anion. These conclusions, and practical considerations lead to the choice of quaternized Astra Blue 6GLL as a replacement for Alcian Blue (now no longer manufactured). It is superior to Alcian Blue in pH range, and stability in solution. It is easily prepared from a readily available precursor.
Ibandronate: A Comparison of Oral Daily Dosing Versus Intermittent Dosing in Postmenopausal Osteoporosis (2001)

The objective of this study was to compare efficacy and safety of continuous versus intermittent oral dosing of ibandronate. Two hundred forty women aged 55-75 years with postmenopausal osteoporosis were randomized to active treatment or placebo. Similar total doses of ibandronate were provided by treatment regimens with either continuous 2.5 mg of ibandronate daily (n = 81) or intermittent 20 mg of ibandronate every other day for the first 24 days, followed by 9 weeks without active drug (n = 78). The placebo group (total, n = 81) was crossed over after 12 months to receive either continuous (n = 37) or intermittent ibandronate (n = 35). By 24 months, bone mineral density (BMD) had increased significantly relative to baseline in both active treatment groups. The continuous and intermittent groups showed statistically equivalent increases in lumbar spine BMD of +5.64% (+/-0.53) and +5.54% (+/-0.53) and in total hip of +3.35% (+/-0.40) and +3.41% (+/-0.40), respectively (per protocol population). Biochemical markers of bone turnover decreased significantly in both treatment groups. The level of marker suppression was similar, although the intermittent group displayed, as expected, more fluctuation over the treatment period. The frequency of adverse events was similar in the treatment groups. In conclusion, the intermittent and continuous regimens showed equivalent changes in BMD and bone turnover. These results confirm previous preclinical findings indicating that the efficacy of ibandronate depends on the total oral dose given rather than on the dosing schedule. This supports development of new flexible dosing regimens targeted to minimize the frequency of dosing, which are expected to improve convenience and lead to enhanced long-term patient compliance.
Design Principles for Trap-Free CsPbX<sub>3</sub> Nanocrystals: Enumerating and Eliminating Surface Halide Vacancies with Softer Lewis Bases (2018)

We introduce a general surface passivation mechanism for cesium lead halide perovskite materials (CsPbX<sub>3</sub>, X = Cl, Br, I) that is supported by a combined experimental and theoretical study of the nanocrystal surface chemistry. A variety of spectroscopic methods are employed together with ab initio calculations to identify surface halide vacancies as the predominant source of charge trapping. The number of surface traps per nanocrystal is quantified by <sup>1</sup>H NMR spectroscopy, and that number is consistent with a simple trapping model in which surface halide vacancies create deleterious under-coordinated lead atoms. These halide vacancies exhibit trapping behavior that differs among CsPbCl<sub>3</sub>, CsPbBr<sub>3</sub>, and CsPbI<sub>3</sub>. Ab initio calculations suggest that introduction of anionic X-type ligands can produce trap-free band gaps by altering the energetics of lead-based defect levels. General rules for selecting effective passivating ligand pairs are introduced by considering established principles of coordination chemistry. Introducing softer, anionic, X-type Lewis bases that target under-coordinated lead atoms results in absolute quantum yields approaching unity and monoexponential luminescence decay kinetics, thereby indicating full trap passivation. This work provides a systematic framework for preparing highly luminescent CsPbX<sub>3</sub> nanocrystals with variable compositions and dimensionalities, thereby improving the fundamental understanding of these materials and informing future synthetic and post-synthetic efforts toward trap-free CsPbX<sub>3</sub> nanocrystals.
Control Camera and Light Source Positions using Image Gradient Information (2007)

In this paper, we propose an original approach to control camera position and/or lighting conditions in an environment using image gradient information. Our goal is to ensure a good viewing condition and good illumination of an object to perform vision-based task (recognition, tracking, etc.). Within the visual servoing framework, we propose solutions to two different issues: maximizing the brightness of the scene and maximizing the contrast in the image. Solutions are proposed to consider either a static light and a moving camera, either or a moving light and a static/moving camera. The proposed method is independent of the structure, color and aspect of the objects. Experimental results on both synthetic and real images are finally presented.
Nodalization Applied to Helicopters (1973)

<div class="htmlview paragraph">A new passive vibration isolation method has been developed which offers less static deflection and lower transmissibility at the operating frequency than conventional passive isolators. The method consists of attaching the object to be isolated to nodal points which are developed when an elastic beam is excited by a vibrating source. Attachment at the nodes dynamically decouples the driving and driven systems in a frequency band making isolation independent of the mass of the driven system. The immediate application is to eliminate helicopter fuselage vibration; however, because of its generality, it can be used wherever conventional isolators are used in isolating a limited range of vibration frequencies.</div>
An investigation of dapsone compliance using an isoniazid-marked formulation (1983)

In a study conducted among out-patients in Hyderabad, it was shown that the precision of the dapsone/creatinine method for monitoring dapsone compliance could be improved if patients were prescribed specially fo rmulated dapsone capsules containing 6 mg isoniazid as an innocuous marker. Urine samples were obtained by means of surprise home visits; the ingestion of the isoniazid marker was revealed by a simple colorimetric procedure which gives reliably positive results for about 18 h. The study showed that such capsules were acceptable to the patients and, in the short run, were taken more regularly than the standard tablets. However, a small proportion of patients took both capsules and tablets very irregularly, indicating that poor compliance was not overcome by simply changing the dapsone formulation.
