Biochemistry of bladder cancer invasion and metastasis. Clinical implications.

SUMMARY In bladder cancer, the finding of infiltration signals the capability of a tumor to behave in an aggressive manner and potentially create a life-threatening situation. The ability to invade is carried in the tumor cell's complement of biochemical pathways as well as in its inability to preserve or restore rather than to disrupt normal tissue architecture. What determines the activation and deployment of these biochemical activities is unclear. That they occur, however, and can distinguish aggressive cancers likely to metastasize from cancers whose behavior is benign, is not. Recognizing and identifying these distinctions is an important step in designing new therapies to prevent a tumor's potential aggressive behavior, possibly reverse or at least contain any extensions that have occurred, and ultimately convert a potentially life-threatening situation to one with a more benign prognosis.
Peer victimization linked to negative affect in children with and without ADHD

Abstract Objective Children with ADHD are more likely to experience peer victimization relative to unaffected peers. Affect appears to be an important factor in determining which children are likely to experience peer victimization, as peers typically prefer children who demonstrate less negative and more positive affect. In this study, we explored the association between child affect and peer victimization in children with and without ADHD. Method One hundred and four 8–12 year old children (59 ADHD, 45 non-ADHD) and their parents completed measures of peer victimization. Parents completed an Ecological Momentary Assessment protocol whereby they rated the child's affect three times daily for 28 days. Results Hierarchical linear regression analyses significantly supported the relation of negative affect to peer victimization in both child- and parent-report, with parent-report of peer victimization moderated by child ADHD diagnostic status. Conclusion Overall, this study suggested that negative affect plays an important role in peer victimization in children with and without ADHD.
Plenary lecture III: intrusion detection in modern optical networks and countermeasures

Optical networks are considered to be intrusion-resistant by virtue of the fiber medium. the common belief is that the optical fiber is difficult to tap, as compared to copper wire and to wireless media. In fact, this is a simplistic view because stripping a cable and tapping a fiber with tools that are commercially available is a relatively simple task to the sophisticated intruder. Moreover, because the fiber link is many kilometers long, the fiber cannot be guarded; this presents a tremendous opportunity and flexibility to the intruder to select the point of intrusion unnoticed. Therefore, it is important that the network is sophisticated enough to monitor and detect intrusions, differentiate from possible component failure and degradation, and upon detection of fiber attacks, it executes automatic countermeasures, outsmarting the intruder. In this talk, we describe automatic intrusion detection methods and countermeasure strategies in modern optical networks.
A Purple Primaries Protocol for Progressive Policy Victories in "Deep Red" American States

An interpretive monopoly is a narrative that defines what one must believe or do to maintain status with an ingroup while simultaneously creating a disfavored outgroup. The oppression of gays and lesbians can easily be traced to dominant narratives that function as interpretive monopolies. Because of how gays and lesbians are marginalized by interpretive monopolies, this article looks not only at the narrative communities that support oppressive narratives, but at the institutions that sustain them. Functioning as homogeneous policy networks in America's "deep red" states, these sustaining institutions have created a political climate in which some interpretive monopolies have become the law of the land. Based on this theoretical approach, a novel solution is proposed: an information communication technology that will facilitate the efficient functionality of expansive heterogeneous policy networks. In the process, a mechanism for changing the outcomes of Tea Party-dominated primary elections emerges as a...
Thermodynamic analysis of a directly heated oxyfuel supercritical power system

Abstract Directly heated supercritical oxy-fuel gas turbines have potential to provide a higher thermal efficiency and lower pollutant emissions compared to current gas turbine systems. Motivated by the advantages of an oxyfuel-based directly heated supercritical power system, this paper presents an analysis of different operating conditions using ASPEN HYSYS®. This study first investigates the efficiency of gaseous or liquid methane and oxygen feed systems. T-s and P-v diagrams are generated and compared to each other to determine which is more efficient. The analysis revealed that the entropy generated during the combustion process for a liquid feed system is approximately three times higher than when methane and oxygen are compressed in gaseous form and delivered to the combustor and burned. To mitigate the high temperatures (3300 K) of the methane and oxygen combustion reaction, carbon dioxide is recirculated. For this portion of the system, the use of gaseous and liquid carbon dioxide recirculation loops and their corresponding efficiencies are determined. The investigation shows that the system yielded a higher net efficiency of 55.1% when gaseous carbon dioxide is recirculated as a diluent with liquid methane and oxygen delivery to the combustor.
Neurofilament Transport in Axonal Regeneration

Regenerating axons have been intensively studied with regard to the mechanisms and determinants of elongation, and several lines of evidence suggest that the delivery of cytoskeletal proteins (tubulin and actin, in particular) are correlates of outgrowth and may be rate limiting (see Lasek and Hoffman, 1976; Wujck and Lasek. 1983). In addition lo changes in axonal length, regeneration involves marked changes in axonal caliber and in cytoskeletal composition. The rcgcneraling axon provides the best available system in which to test critically the hypotheses underlying several of our recent studies. These hypotheses are that neurofilament content is the major correlate of axonal caliber and that axonal neurofilament content is, in turn, determined, in large part, by neurofilament delivery via slow axonal transport. This review will first summarize the general problem of the determinants of axonal caliber and then focus on recent data from regenerating nerves. These data can be considered in terms of three regions of the regenerating axon—the proximal stump, the maturing sprouts, and the distal sprouts.
The Postsynaptic Density: There Is More than Meets the Eye.

The postsynaptic density (PSD), apparent in electron micrographs as a dense lamina just beneath the postsynaptic membrane, includes a deeper layer, the “pallium,” containing a scaffold of Shank and Homer proteins. Though poorly defined in traditionally prepared thin-section electron micrographs, the pallium becomes denser and more conspicuous during intense synaptic activity, due to the reversible addition of CaMKII and other proteins. In this Perspective we review the significance of CaMKII-mediated recruitment of proteins to the pallium with respect to both the trafficking of receptors and the remodeling of spine shape that follow synaptic stimulation. We suggest that the level and duration of CaMKII translocation and activation in the pallium will shape activity-induced changes in the spine.
Benefit assessment of water-heater management on residential demand response: An event driven approach

Analysis, modeling and development of residential demand response schemes are vital for the next generation active distribution systems. Among residential level deferrable loads thermally controllable loads have shown a great potential to be the candidates for increasing the flexibility of power distribution network. This paper evaluates the benefits of managing residential electric water heater set-points to reduce the overall cost of electricity in the presence of day-ahead forward price at distribution level. Three unique features, (i) consumer comfort by providing more hot water at the time of usage, (ii) reducing residential indoor temperature variations and (iii) reducing the health concerns due to water temperature regulations are addressed in this work. Randomly specified residential units, along with the thermal dynamics are used. ASHRAE standards are used in this work to ensure physical limitations are accurately represented. The results show that appropriately controlling the water heater temperature will be of great value to both utility and consumer demand response programs.
Towards a Machine-Oriented Aesthetics: On the Power of Art

The paper deals with the problem of a position of art as traditionally seen from the field of philosophy; more precisely, it points to the core of this philosophical attitude which marginalizes art, treating it as prosthesis, almost erasing it. Investigating the terms such as Beauty and expressivism, this paper addresses the problem of materiality of art, leading it to the questions of meaning, doing and producing. Using Deleuze and Guattari’s theories, author turns to a machine-oriented aesthetics, which affects everything inside and outside of its field in its pluripotency. In the other words, what is explained and proposed is a kind of machinic-oriented aesthetics, as something which is able to capture something of the difference that the artwork makes.
Dried blood spots: An evaluation of utility in the field.

Abstract Background Use of dried blood spots (DBS) offers advantages over serum samples in studies conducted in resource-poor settings. The aim of this study was to compare the number of adequate spots collected across different demographic groups. Methods Five DBS were collected from 3316 individuals aged 0–49 years in Tianjin, China for a measles antibody study; DBS were rated “adequate” or “inadequate.” Linear regression, with the number of adequate DBS on a card as the outcome variable, was used to test for predictors of DBS adequacy. Results There were 0 adequate DBS for 23% of participants and 5 adequate DBS for 24%. Mean number of adequate DBS was 1.68 in infants ( Conclusions DBS are an alternative for adults and children but pose challenges in infants, and improve with experience. In a resource-limited environment or in a scenario where more invasive techniques like venipuncture may be less accepted by the study population, DBS can be the preferred technique to efficiently obtain serum specimens for analyte testing.
Direct Substrate Identification with an Analog Sensitive (AS) Viral Cyclin-Dependent Kinase (v-Cdk).

Viral cyclin-dependent kinases (v-Cdks) functionally emulate their cellular Cdk counterparts. Such viral mimicry is an established phenomenon that we extend here through chemical genetics. Kinases contain gatekeeper residues that limit the size of molecules that can be accommodated within the enzyme active site. Mutating gatekeeper residues to smaller amino acids allows larger molecules access to the active site. Such mutants can utilize bio-orthoganol ATPs for phosphate transfer and are inhibited by compounds ineffective against the wild type protein, and thus are referred to as analog-sensitive (AS) kinases. We identified the gatekeeper residues of the v-Cdks encoded by Epstein–Barr virus (EBV) and human cytomegalovirus (HCMV) and mutated them to generate AS kinases. The AS-v-Cdks are functional and utilize different ATP derivatives with a specificity closely matching their cellular ortholog, AS-Cdk2. The AS derivative of the EBV v-Cdk was used to transfer a thiolated phosphate group to targeted protein...

Which Interventions Are Useful

Many interventions have been tested to improve medication adherence. Interventions can vary from simple pillboxes or blister packs to complex interventions with considerable involvement of health care providers and/or technology. This chapter provides some suggestions for intervention approaches. Both providers and researchers must also keep in mind, however, that adherence interventions are not universally effective for all patients or populations. When seeking to improve adherence, the best results are likely going to be achieved by tailoring approaches to the situations and needs of individual patients.
Trapping and Other Strategies for Control of Cucumber Beetle in Muskmelon

Introduction Spotted and striped cucumber beetles (Diabrotica undecimpunctata howardi and Acalymma vittata) that vector a bacteria that causes bacterial wilt in cucurbits are the major pest in Iowa muskmelon fields. Growers currently spray insecticides to control these insects on a oneto two-week preventive schedule. Use of large amounts of chemical can be expensive and damaging to beneficial pollinators and the environment. We investigated the success of the prototype Trece trap-and-bait system—soon to be Organic Materials Review Institute approved— in controlling these beetles. The traps chemically lure beetles to insecticide-treated baits inside the traps, placed some distance away from the muskmelon crop. We also tested three other management methods in combination with the traps: Reemay® row covers, slitted row covers, and transplants treated with BioYield® (rhizobacterial) potting soil.
Nerve Blocks, Trigger Points, and Intrathecal Therapy for Chronic Pain

Pain, an experience that is both sensory and emotional, profoundly affects an individual’s physiological and psychological being. It should be managed in the context of the whole person. Interventional pain management is best practiced as an aspect of a multidisciplinary approach for pain relief. This chapter will provide an overview of the common peripheral nerve, neuraxial and sympathetic blocks, trigger point injection, and intrathecal therapy for chronic pain from diseases across the life course. Discussions will also provide sufficient details on how the procedures are performed, their efficacy and complications.
Insulin-like growth factor binding proteins in the nervous system.

Insulin-like growth factor binding proteins (IGFBPs) are a group of discrete but structurally related polypeptides,1–3 which bind and modulate the biological activity of insulin-like growth factors (IGFs) I and II.4–9 Since available evidence suggests that IGF-I and -II participate in growth, metabolism, differentiation, and injury repair,10–24 to name just a few biologic processes in which IGFs are implicated, IGFBPs may have important regulatory actions in these and other diverse biological processes.
Neuromuscular Junction (NMJ): Postsynaptic Basal Lamina

The extracellular matrix occupying the space between the nerve terminal and the muscle cell is the synaptic basal lamina. The synaptic basal lamina serves at least two important roles. First, it is a mechanical link that tightly attaches the nerve terminal to the twitching muscle cell. Second, there are molecules in the synaptic basal lamina that are crucial for the cell-to-cell signaling that is required for the function of the synapse. Molecules in the synaptic basal lamina are regulated by proteases that remove specific components. Thus, the synaptic basal lamina is integral to the structure and function of the synapse.
Multivariate Analyses of Risk Factors for Noncontact Anterior Cruciate Ligament Injuries

This chapter reviews investigations that have used multivariate approaches to determine the risk factors associated with increased risk of suffering ACL injury. One study assessed the effect of sport, level of play, and gender. Other studies analyzed the effect of demographic characteristics, joint laxity, lower extremity alignment, and strength. Several investigations have assessed the effect of knee geometric characteristics in increasing the incidence of noncontact ACL injury.

ThreatZoom: neural network for automated vulnerability mitigation

Increasing the variety and quantity of cyber threats becoming the evident that traditional human-in-loop approaches are no longer sufficient to keep systems safe. To address this momentous moot point, forward-thinking pioneers propose new cyber security strategy using automation to build a more efficient and cheaper defense. Associating large number of unpatchable CVEs (vulnerability descriptions) generated everyday to appropriate CWE (weakness) and CAPEC (attack pattern) can be used to automatically infer the expected impact and corresponding mitigation course of actions for that new CVE. Routinely, adversary exploits a vulnerability to trigger a cyber attack where this vulnerability results from a product or system weakness. Hence, finding a common system weakness associated with a vulnerability within a particular product can help to identifying the software, system, or architecture flaw and the potential attack impacts. This identification leads to prevent, detect, and mitigate those flaws. On the other hand, after recognizing the cause and the effect of a vulnerability, discovering the procedural-oriented description of the attack to create behavioral observables for detection and mitigation is necessary that can be derived from CAPEC and ATTCK. Mapping the CWE to CAPEC and ATTCK which provides pre-TTP and post-TTP respectively where TTP stands for Tactics, Techniques, and Procedures. Having all CWE, CAPEC, and ATTCK in one hand enables us to find corresponding mitigation for each one. On the other hand, extracting threat actions provided by each of these concepts leads to find another type of mitigation coming from Critical Security Controls (CSC).In this proposal, the target is to do mapping all the way from CVE to CAPEC and ATTCk automatically using machine learning, deep learning, and natural language processing and find the appropriate mitigation for each one and then find a proper patch as course of action defense. So far, we have introduced a neural network model which successfully classifies CVE to CWE automatically and as working on a deep learning model to classify CWEs to CAPEC.
Urban background noise affects breeding song frequency and syllable-type composition in the Northern Mockingbird

The Northern Mockingbird (Mimus polyglottos) is a successful urban adaptor known to display flexibility in foraging, nesting, and anti-predator behavior. Its vocal behavior is also complex, with a breeding song composed of a wide variety of non-mimetic and mimetic elements, or “syllable types.” We tested the hypothesis that Northern Mockingbird adaptation to urban settings includes changes in its vocal behavior in noisy urban environments. We studied an urban/suburban mockingbird population to test the effect of urban background noise on breeding song frequency and syllable-type composition. Given that urban noise overlaps most strongly with low-frequency vocalizations, a phenomenon known as “signal masking,” we predicted a positive association between noise levels and mockingbird average peak frequency (a measure of vocalization power). We further predicted a positive effect of noise levels on the peak frequency of the lowest-pitched syllable type in a mockingbird's song, no effect on the peak frequency of the highest-pitched syllable type, and thus a negative effect on mockingbird peak frequency range. Lastly, we predicted a negative effect of background noise on the use of syllable types experiencing heavy signal masking and, conversely, a positive effect on the use of syllable types experiencing minimal signal masking. We found a significant positive effect of noise levels on both average peak frequency and peak frequency of the lowest-pitched syllable type, but no effect on the peak frequency of the highest-pitched syllable type and peak frequency range. In addition, as background noise levels increased, we found significant declines in the percentages of heavily masked syllable types (1–3 kHz) and significant increases in the percentages of syllable types in the 3–5 kHz range; percentages of syllable types >5 kHz were, however, unaffected by background noise. These results were consistent with the hypothesis that Northern Mockingbird breeding songs change in pitch and syllable-type composition in noisy settings, providing further evidence that songs of urban-adapting species differ in noisy environments.

A Precision Bandgap Voltage Reference Using Curvature Elimination Technique

A bandgap voltage reference circuit using a curvature elimination approach is proposed. Curvature elimination is achieved by a weighted subtraction of the outputs of two basic bandgap circuits that have the same functional form as the curvature. The reference is implemented in a 130nm CMOS process and generates a nominal output voltage of approximately 1.24V. Simulation results predict the proposed circuit can achieve a temperature coefficient of 0.5ppm/°C over the temperature range from 0°C to 100°C.
Generational and Time Period Differences in American Adolescents’ Religious Orientation, 1966–2014

In four large, nationally representative surveys (N = 11.2 million), American adolescents and emerging adults in the 2010s (Millennials) were significantly less religious than previous generations (Boomers, Generation X) at the same age. The data are from the Monitoring the Future studies of 12th graders (1976–2013), 8th and 10th graders (1991–2013), and the American Freshman survey of entering college students (1966–2014). Although the majority of adolescents and emerging adults are still religiously involved, twice as many 12th graders and college students, and 20%–40% more 8th and 10th graders, never attend religious services. Twice as many 12th graders and entering college students in the 2010s (vs. the 1960s–70s) give their religious affiliation as “none,” as do 40%–50% more 8th and 10th graders. Recent birth cohorts report less approval of religious organizations, are less likely to say that religion is important in their lives, report being less spiritual, and spend less time praying or meditating. Thus, declines in religious orientation reach beyond affiliation to religious participation and religiosity, suggesting a movement toward secularism among a growing minority. The declines are larger among girls, Whites, lower-SES individuals, and in the Northeastern U.S., very small among Blacks, and non-existent among political conservatives. Religious affiliation is lower in years with more income inequality, higher median family income, higher materialism, more positive self-views, and lower social support. Overall, these results suggest that the lower religious orientation of Millennials is due to time period or generation, and not to age.
Safety of micro-mobility: Analysis of E-Scooter crashes by mining news reports.

Abstract Dockless electric scooters (E-Scooters) have emerged as a popular micro-mobility mode for urban transportation. This new form of mobility offers riders a flexible option for massive first-/last-mile trips. Despite the popularity, the limited regulations of E-Scooters raise numerous safety concerns among the public and agencies. Due to the unavailability of well-archived crash data, it is difficult to understand and characterize current state quo of E-Scooter-involved crashes. This paper aims to shorten the gap by analyzing a set of reported crash data to describe the patterns of crashes related to E-Scooter use. Specifically, massive media reports were searched and investigated for constructing the crash dataset. Key crash elements such as rider demographics, crash type, and location were organized in an information table for analysis. From 2017 to 2019, there were 169 E-Scooter-involved crashes identified from the news reports across the country. Through the descriptive analysis and cross tabulation analysis, the distinct characteristics of these reported crashes were highlighted. Overall, there was a growing trend for the reported E-Scooter-involved crashes unevenly distributed among the States. The distribution of the crashes across different groups of users, facilities, time periods, and severity levels also showed skewed patterns toward a subset of categories. The quantitative analyses also provide some supportive evidences for warranting the discussion on key issues, including helmet use, riding under influence (RUI), vulnerable riders, and data deficiency. This study highlights the importance of public awareness and timely developing safety countermeasures to mitigate crashes involving E-Scooters.
High-sensitivity CEST mapping using a spatiotemporal correlation-enhanced method.

Purpose To obtain high-sensitivity CEST maps by exploiting the spatiotemporal correlation between CEST images. Methods A postprocessing method accomplished by multilinear singular value decomposition (MLSVD) was used to enhance the CEST SNR by exploiting the correlation between the Z-spectrum for each voxel and the low-rank property of the overall CEST data. The performance of this method was evaluated using CrCEST in ischemic mouse brain at 11.7 tesla. Then, MLSVD CEST was applied to obtain Cr, amide, and amine CEST maps of the ischemic mouse brain to demonstrate its general applications. Results Complex-valued Gaussian noise was added to CEST k-space data to mimic a low SNR situation. MLSVD CEST analysis was able to suppress the noise, recover the degraded CEST peak, and provide better CrCEST quality compared to the smoothing and singular value decomposition (SVD)-based denoising methods. High-resolution Cr, amide, and amine CEST maps of an ischemic stroke using MLSVD CEST suggest that CrCEST is also a sensitive pH mapping method, and a wide range of pH changes can be detected by combing CrCEST with amine CEST at high magnetic fields. Conclusion MLSVD CEST provides a simple and efficient way to improve the SNR of CEST images.

Postoperative healing in the diabetic foot is impacted by discharge destination

The aim of this study was to evaluate the impact of discharge destination on diabetes-related limb salvage surgery outcomes post-hospitalisation. This was a single-centre, observational, descriptive study of 175 subjects with diabetes who underwent limb salvage surgery of a minor foot amputation or wide incision and debridement for an acutely infected diabetic foot ulcer (DFU). Comparisons were made between subjects discharged home vs a skilled nursing facility (SNF) for 12 months postoperatively. Univariate, multivariate, and time-to-event analyses were performed. The SNF discharge group (n = 40) had worse outcomes with longer healing time (P = .022), more rehospitalisations requiring a podiatry consult (P = .009), increase of subsequent ipsilateral major lower-extremity amputation (P = .028), and a higher mortality rate (P = .012) within the 12-month postoperative period. There was no significant difference between the cohorts in surgically cleared osteomyelitis (P = .8434). The Charlson Comorbidity Index values for those discharged home and those in a short-term nursing facility were similar (P = .3819; home x ¯ =5.33 ± 2.84 vs SNF x ¯ =5.75 ± 2.06). The planned discharge destination after limb salvage surgery among people with an acutely infected DFU should be an added risk factor for healing outcomes. Patients discharged to SNFs experience additional morbidity and mortality compared with patients discharged home post-hospitalisation.
Message-of-the-Day (MOTD) Banner Language Variations as an Adaptive Honeypot Deterrent of Unauthorized Access

This study investigates the effect of a Message-of-the-Day (MOTD) system banner, written in three languages: English, Russian, and Chinese, on deterring unauthorized access to publicly accessible systems. Banners have been used in both the physical and cyberspace realms as a method of signalling to trespassers that the defending entity is aware of, and directing against, malicious activity. We created a honeypot infrastructure with three ssh servers for each language variant, and measured the attempts of unauthorized access over a course of a regular week. The results suggest that the MOTD banner written in Russian attracted at least twice as many attempts of unauthorized access as the English and Chinese MOTD banners. The Russian MOTD banner received 38% of the attempts from US IP addresses with 3.710 failed password login attempts per session and 51% of the attempts from Chinese IP addresses with 2.958 failed password login attempts per session on average. This ratio, on the English MOTD banner, was US IP addresses: 52%, 3.986 failed password login attempts and Chinese IP addresses: 27%, 2.367 failed password login attempts. On the Chinese MOTD banner this ratio was US IP addresses: 48%, 2.568 failed password login attempts and Chinese IP addresses: 27%, 2.858 failed password login attempts. We discuss the implications of these results for incorporating language variations in MOTD banners as a deterrence strategy.

Design and Control of Hoverable Bionic Flapping Wing Micro Air Vehicle

Hoverable Flapping Wing Micro Air Vehicle (FWMAV) is a new concept aircraft which imitates the flight mode of hummingbirds or insects. It has excellent mobility, flexibility, concealment, and can demonstrate hovering, forward flight and other maneuvers, which has attracted wide attention. In this research, a prototype of hoverable FWMAVs is designed and built for the research of control method, and the research on flight attitude estimation and attitude control algorithm are carried out. The hardware devices such as flight control board and remote control are designed and developed independently, also we devised the software control system to realize the communication between software and hardware, then the algorithm is verified on the experimental platform. The prototype of the aircraft weighs 27.24g, and can take off under the flapping frequency of 20Hz. On the experimental platform, relying on the hardware control circuit and software control algorithm, it can realize the attitude control of roll and pitch, and demonstrate hovering flight for two minutes.
Self-Organized Teams: A Contradictory Technique to Motivate Personnel

The self-organized team is a core technique in the modern software development methodologies known as agile techniques. It improves the ability of a team to make efficient decision and move a project toward the ultimate goal. This technique has been recognized as a motivational practice in many companies, while in others applying it produced a sufficient negative impact. In this article the meaning of the practice is revised. We study cases when applying it would have positive or negative effect and how we can improve the efficiency of that even in a negative case.
Triacylglycerol Movement in Enterocytes

This chapter covers the movement of triacylglycerols (TGs) within enterocytes. Relatively little is known about how TG vectorially transits the intestinal absorptive cell compared to other aspects of intestinal cellular function. Intracellular TG movement is important because in humans, the intestine must absorb 100 to 150 gm of fat per day on a typical Western diet, which, if inefficiently done, may result in steatorrhea, the excessive excretion of fat in the stool, and may also lead to fat-soluble vitamin deficiencies. Normally, the end result of the complex process of lipid absorption is the export of TG containing long-chain fatty acids (FA) into the lymph in a unique, specialized lipoprotein particle, the chylomicron (Green and Glickman, 1981) and a slightly more dense particle, the very low density lipoprotein (VLDL, Ockner et al., 1969b; Tso et al, 1987). More recent studies have begun to shed some light on how TG moves from its site of synthesis in the endoplasmic reticulum (ER) to its exit site at the basolateral membrane of the enterocyte as shown schematically in Fig. 1.
A Note on Deconstruction

For example, Paul de Man: "A deconstruction always has for its target to reveal the existence of hidden articulations and fragmentations within assumed monadic totalities." He is telling us that language qualifies what it says. Deconstructionists, keen on "sub-texts" promoted by the uncon scious, think it does this involuntarily. They don't give the writer much credit. But literary language at its highest reach (poetry), often testifies against itself, wittingly too. Life, endlessly tangled, is the poet's business, and the questions it raises need yes-and-no answers. You won't catch de Man & Co. putting it that way, however. Still, the "hidden" meanings part, though turning literary study into a parlor game, gets two cheers from me. At least it improves on thus-we-see critics who make the text redundant except for its punch line. Husserl, a spokesman for deconstruction's German wing, calls their ideational kernel Bedeutung. (Less sophisticated readers call it the "moral.") He and associates agree that its version of meaning is partial. The opposite of partial isn't plenary, though, not on their reading, and deconstruction's ideal text is amorphous. Derrida's "Des Tours de Babel" (1985), evading the rigid structures Bedeutung insists on, sponsors more meanings than we know what to do with. This plenitude, or rather surfeit, is "post-structuralist" exactly and sees to it that meaning dies "of its own too much." "Des" is "some," also "from the" or "concerning," while "tours," meaning "towers," means "twists" and "turns," including "turns of phrase." Put the first two words in the title together and they sound like "detour," descriptive of the text. "Babel" is a place name, that is, itself alone, but signifies the confusion of tongues. You can't clear it up, either: "no theorization, inasmuch as it is produced in a language, will be able to dominate the Babelian perfor mance." But check out Derrida's approximation and see.
The Asymptotic Equivalence of Investing with and without Replacement

Consider the following scenarios for a sequence of vectors X/sub1/, X/sub 2/,..., X/sub n/ of price relatives corresponding to the history of a finite collection of stocks over a period of n investment periods: 1) Nothing is known about the sequence of vectors; 2) The vectors in the sequence are known, although the order is not known and the vectors are drawn independently with replacement from this set; 3) The collection of vectors is known, although the order is unknown, but the vectors are drawn without replacement from this set.
Cultural, Biochemical, and Immunological Properties of Mima, Herellea, and Flavobacterium Species

From study of cultural and biochemical characteristics of 40 strains of Herellea, Mima, or Flavobacterium species, a proposed schema for identification was developed. The reactions observed by agglutination, gel diffusion, and immunofluorescence suggest antigenic heterogeneity of this group of organisms.
Course 3 - Geometric Singular Perturbation Analysis of Neuronal Dynamics

The chapter discusses models for neuronal systems and dynamical systems methods for analyzing these models. The discussion focuses primarily on models which include a small parameter and results in which geometric singular perturbation methods are used to analyze the network behavior. An informal introduction to the geometric theory of dynamical systems is presented. The notions of phase space, local and global bifurcation theory, stability theory, oscillations, and geometric singular perturbation theory are described. All of these techniques are very important in the analysis of models for neuronal systems. The chapter explains how dynamical systems methods are used to analyze properties of a single neuron model. The dynamics of small networks of neurons are discussed. Conditions are given for when these networks exhibit either synchronous or desynchronous rhythms. This analysis easily generalizes to larger systems where excitatory-inhibitory networks are considered. The chapter presents a discussion on a model for activity patterns in the Basal Ganglia, a part of the brain involved in the generation of movements.
Museum spaces as psychological affordances: representations of immigration history and national identity.

The present research draws upon a cultural psychological perspective to consider how psychological phenomena are grounded in socio-cultural contexts. Specifically, we examine the association between representations of history at Ellis Island Immigration Museum and identity-relevant concerns. Pilot study participants (N = 13) took a total of 114 photographs of exhibits that they considered as most important in the museum. Results indicate that a majority of the photographs reflected neutral themes (n = 81), followed by nation-glorifying images (n= 24), and then critical themes that highlight injustices and barriers faced by immigrants (n= 9). Study 1 examines whether there is a preference for glorifying images, and if that preference is related to cultural-assimilationist conceptions of national identity (i.e., defining American identity in dominant group standards). We exposed a new sample of participants (N = 119) to photographs reflecting all three themes. Results indicate that participants expressed greater liking for glorifying images, followed by neutral images, and critical images. National identity moderated within-subject variation in liking scores. Study 2 included 35 visitors who completed a survey before engaging with the museum or after their visit. Results indicate that participants who had completed their visit, compared to participants who had not entered the museum, reported (i) higher endorsement of cultural-assimilationist identity, and (ii) increased support for exclusive immigration policies. Study 3 exposed participants (N = 257) to glorifying, critical, or neutral images. Results indicate that participants who were exposed to glorifying images, especially those endorsing cultural-assimilationist identity, demonstrate decreased perception of current-day racial injustice, and increased ethnocentric enforcement bias. We discuss how engagement with privileged narratives may serve dominant group ends and reproduce systems of privilege.
Pragmatic estimates of the proportion of pediatric inpatients exposed to specific medications in the USA.

Purpose To provide pragmatic national estimates of the proportion of hospitalized pediatric patients exposed to specific drugs in the USA. Methods We used Premier Perspective Database and the Pediatric Health Information System data including specific drug exposures of 1.15 million inpatients <18years old in 411 general and 52 children’s hospitals throughout the USA in 2006, extrapolating this information into the probability-based Kids’ Inpatient Database, which has demographic and clinical characteristics but no drug exposure data. We used a multivariable stratified resampling (MSR) technique to estimate the proportion of drug exposure for the 700 most commonly used drugs and performed additional stability and sensitivity analyses for 19 drugs. Results The estimated proportion of pediatric inpatients exposed to specific drugs in 2006 ranged from high levels such as that of acetaminophen (17.36; 95%CI: 17.32, 17.41) to rare exposures such as bosentan (0.0018; 95%CI: 0.0013, 0.0023). Additional analyses for 19 drugs revealed that the MSR estimates were close to estimates generated by multivariable multiple imputation, with a maximum absolute difference of 0.03 for acetaminophen (17.36 vs. 17.33) and famotidine (1.90 vs. 1.93), and that even with 50% of the hospitals removed at random, the proportion estimates did not vary by more than 2.5-fold at the upper 97.5 percentile. Conclusions These pragmatic national estimates of the proportion of pediatric inpatient drug exposures, generated using an MSR technique, provide a context for interpretation of drug-related adverse event reports and prioritization of pediatric pharmacology research. © 2013 The Authors.

Trends in the disapproval and use of marijuana among adolescents and young adults in the United States: 2002–2013

AbstractBackground: Despite policy changes related to the use and distribution of marijuana in cities and states across the country, few studies have examined changes in disapproval and use of marijuana among American youth. Objectives: To examine trends in disapproval and use of marijuana among adolescents and young adults in the United States. Method: We employed nationally representative data spanning the period of 2002–2013. Analyses were based on self-reported measurements from 105,903 younger adolescents (aged 12–14); 110,949 older adolescents (aged 15–17); and 221,976 young adults (aged 18–25). Results: Between 2002 and 2013 the proportion of adolescents aged 12–14 reporting “strong disapproval” of marijuana use initiation increased significantly from 74.4–78.9%. Concurrently, a significant decrease in past 12-month marijuana use (OR = 0.98, 95% CI = 0.97–0.99) was observed among younger adolescents. No significant trend was observed for marijuana use disapproval among adolescents aged 15–17 betwee...
Multi-pulse electron diode development for flash radiography

Presently the Self Magnetic Pinch (SMP) diode is successfully utilized for flash radiography with pulsed power drivers. However, it is not capable of more than one pulse. Multi-pulse single-axis radiography is most preferred since it provides images of time-evolving dynamic targets. In an SMP diode, because the anode cathode (A-K) gap is very small (∼1–2 cm), the debris from the anode converter target arrives soon after the first pulse and completely destroy the cathode electron emitter, and thus the diode cannot produce a second pulse. We propose a feasibility study to scientifically evaluate the idea of decoupling the anode converter from the cathode electron emitter. This work will be based on two successful previous works we have accomplished: first, making a very small pencil-like beam in a magnetically immersed foilless diode (M.G. Mazarakis et al., Applied Physics Letters, 7, pp. 832 (1996)); and second, successfully demonstrating the two-pulse operation of a foilless diode with the RIIM accelerator (M. G. Mazarakis et al., Applied Physics 64 part I pp. 4815, (1988) Our approach will combine the above experimentally demonstrated successful work. The generated beam of 40–50 kA will be propagated in the same diode magnetic solenoid for a sufficient distance before striking the converter target. This way the diode could be multi-pulsed before the target debris reaches the cathode. Although the above describes the option of a foilless diode and a solenoidal transport system, a similar design could be made for a non-immersed low emittance 10 kA velvet emitter foilless diode.
