Heidegger on Verfallenheit

The question of Heidegger’s reflections on technology is explored in terms of ‘living with’ technology and including the socio-theoretical (Edinburgh) notion of ‘entanglement’ towards a review of Heidegger’s understanding of technology and media, including the entertainment industry and modern digital life. I explore Heidegger’s reflections on Gelassenheit by way of the Japanese aesthetic conception of life and of art as wabi-sabi understood with respect to Heidegger’s Gelassenheit as the art of Verfallenheit.
Trends in underage tobacco sales: an update on the past decade of compliance checks in Hawai'i

Tobacco use remains the leading cause of preventable death in the United States and is a major concern in the adolescent population. Preventing youth from starting to smoke is a key public health priority, as a majority of adult smokers started smoking by age 18. Controlling access to tobacco in retail outlets has been shown to be an effective measure for reducing the use of tobacco among minors. In order to control the sales of tobacco to minors in the retail environment, the Synar Amendment requires states to conduct annual, random, and unannounced tobacco sales compliance inspections. Synar compliance inspections started in Hawai'i in 1996, reducing the sales of tobacco to minors almost 40.0% by 2003. The current paper aims to expand on past surveillance findings to examine the Synar compliance inspection results in Hawai'i from 2004 to 2013 and to identify factors associated with minors' successfully purchasing tobacco. Surveillance of the past ten years showed that noncompliance rates remained low, ranging from a high of 11.2% in 2008 to a low of 4.3% in 2012; this number was 7.5% in 2013. Three factors were significantly associated with successful tobacco purchases by a minor in 2013: whether a clerk requested a minor's identification, the gender of the minor, and whether self-service of tobacco products was available. Other significant factors varied by year. Findings from this study are needed for continued surveillance, to implement effective anti-tobacco policies, and to develop policies aimed at emerging tobacco products, such as electronic cigarettes.
Solid-to-solid oxidation of a vanadium(IV) to a vanadium(V) compound: chemisty of a sulfur-containing siderophore.

Visible light facilitates a solid-to-solid photochemical aerobic oxidation of a hunter-green microcrystalline oxidovanadium(IV) compound (1) to form a black powder of cis-dioxidovanadium(V) (2) at ambient temperature. The siderophore ligand pyridine-2,6-bis(thiocarboxylic acid), H2L, is secreted by a microorganism from the Pseudomonas genus. This irreversible transformation of a metal monooxo to a metal dioxo complex in the solid state in the absence of solvent is unprecedented. It serves as a proof-of-concept reaction for green chemistry occurring in solid matrixes.
Anticipatory Robot Control for Efficient Human-Robot Collaboration

Efficient collaboration requires collaborators to monitor the behaviors of their partners, make inferences about their task intent, and plan their own actions accordingly. To work seamlessly and efficiently with their human counterparts, robots must similarly rely on predictions of their users' intent in planning their actions. In this paper, we present an anticipatory control method that enables robots to proactively perform task actions based on anticipated actions of their human partners. We implemented this method into a robot system that monitored its user's gaze, predicted his or her task intent based on observed gaze patterns, and performed anticipatory task actions accord- ing to its predictions. Results from a human-robot interaction experiment showed that anticipatory control enabled the robot to respond to user requests and complete the task faster-2.5 seconds on average and up to 3.4 seconds-compared to a robot using a reactive control method that did not anticipate user intent. Our findings highlight the promise of performing anticipatory actions for achieving efficient human-robot teamwork.
Instruments for High Altitude Turbulence Measurements

*† ‡ Three instruments were analyzed to find the most appropriate method of measuring wind velocity fluctuations at an altitude of 60k feet at low velocities. The analysis of these instruments, a pitot-static tube, a propeller anemometer, and an ionic anemometer, was conducted to test the probability of the success of each, as well as make a recommendation as to which could be used onboard the High Altitude Airship (HAA) when it is ready for flight. From initial investigation, it appears that the ionic anemometer is the best instrument at HAA altitudes and speeds. The combination of low speed and low density result in very small total pressure values to use for velocity extraction or for angular acceleration of a propeller.
When Domains Spill Over The Relationships of Affective and Continuance Commitment With Work–Family Conflict Among Correctional Staff

Synthesis and characterization of conductive, biodegradable, elastomeric polyurethanes for biomedical applications

Biodegradable conductive polymers are currently of significant interest in tissue repair and regeneration, drug delivery, and bioelectronics. However, biodegradable materials exhibiting both conductive and elastic properties have rarely been reported to date. To that end, an electrically conductive polyurethane (CPU) was synthesized from polycaprolactone diol, hexadiisocyanate, and aniline trimer and subsequently doped with (1S)-(+)-10-camphorsulfonic acid (CSA). All CPU films showed good elasticity within a 30% strain range. The electrical conductivity of the CPU films, as enhanced with increasing amounts of CSA, ranged from 2.7 ± 0.9 × 10(-10) to 4.4 ± 0.6 × 10(-7) S/cm in a dry state and 4.2 ± 0.5 × 10(-8) to 7.3 ± 1.5 × 10(-5) S/cm in a wet state. The redox peaks of a CPU1.5 film (molar ratio CSA:aniline trimer = 1.5:1) in the cyclic voltammogram confirmed the desired good electroactivity. The doped CPU film exhibited good electrical stability (87% of initial conductivity after 150 hours charge) as measured in a cell culture medium. The degradation rates of CPU films increased with increasing CSA content in both phosphate-buffered solution (PBS) and lipase/PBS solutions. After 7 days of enzymatic degradation, the conductivity of all CSA-doped CPU films had decreased to that of the undoped CPU film. Mouse 3T3 fibroblasts proliferated and spread on all CPU films. This developed biodegradable CPU with good elasticity, electrical stability, and biocompatibility may find potential applications in tissue engineering, smart drug release, and electronics. © 2016 Wiley Periodicals, Inc.

A comparison of engineering controls for formaldehyde exposure during grossing activities in health care anatomic pathology laboratories

ABSTRACTThis article for the first time reports a large set of monitoring results for formaldehyde exposure during grossing activities in health care anatomic pathology laboratories, and compares the effectiveness of different local exhaust ventilation systems on the exposure. To control the confounding effects from grossing work load, sampling duration, and the sizes of specimens grossed, only 15-min short-term personal exposure samples collected during large tissue specimen grossing were used for the comparison of the effectiveness of these local exhaust systems. While we also collected long-term 8-hr time weighted average samples, these are not treated in this analysis. The systems examined were canopy receiving hoods, slot exhausts, and commercially available pre-manufactured backdraft grossing stations, both recirculating and ducted exhaust types. Out of over 2,000 personal short-term air samples, 307 samples from 163 surveys met the data selection criteria. Over a third of the data were less than th...
Finitely Generated Semigroups

This chapter contains basic properties of finitely generated commutative semigroups: Redei’s Theorem, various finiteness properties, and the Completion Theorem. The results indicate that these semigroups are assembled somehow from cancellative semigroups and nilsemigroups, arranged along a finite semilattice. This similarity to finite semigroups is pursued much further in the next chapter.
Populism, heroism, and revolution. Chávez’s cultural performances in Venezuela, 1999–2012

In recent decades, the sociological theory of action has paid a good deal of attention to the concept of performances. This is particularly the case for the Strong Program in Cultural Sociology’s notion of social or cultural performances. The concept presupposes, among other things, that in order to be successful, performances should be harmonic and avoid marked differentiations, sanctioning a dominant cultural structure. This article offers an example of how the opposite may be true, through an analysis of the contentious performances of Hugo Chavez in Venezuela (1999–2012). From these, I identify two main dynamics. One is of condensation, where events and agents are dragged into a populist framework, characterized by the binary opposition of the people vs. elites. The other dynamic is of displacement, where the meaning of revolution is changed (from moral, to political war, to socialist revolution). I conclude that, in the context of a Global South nation like Venezuela, the symbolic environment might be constituted by hybrid cultural structures, and charismatic leaders may interpellate dominant binary codes and highlight other, subordinated ones. This is relevant to stretch the use of performances beyond their original context, and provides clues for a performative theory of cultural change.
Apnea in a Term Infant

A 23-day-old male infant presents to the emergency department with apnea. ### Prenatal and Birth Histories: ### Case Presentation: After being fed and burped, the baby suddenly developed apnea. Emergency medical services were called after a short delay when the father, the primary caregiver, had called his mother and the baby’s mother at work. The duration of apnea was unknown. When the paramedics could not discern a heart rate, they started cardiopulmonary resuscitation and administered epinephrine via an intraosseous line. In the emergency department, a heart rate was obtained after 1 minute of resuscitation, and the infant was transferred promptly to the intensive care unit. The parents reported episodes of flexor posturing with eyes rolling back and tremulousness since birth that they described as seizures. ### Vital Signs: Temperature: 96.6°F (35.9° C) Heart …
Plasticity paves the way in an adaptive radiation

Phenotypic plasticity has been hypothesized to play a central role in the evolution of phenotypic diversity across species (West-Eberhard 2003). Through ‘genetic assimilation’, phenotypes that are initially environmentally induced within species become genetically fixed over evolutionary time. While genetic assimilation has been shown to occur in both the laboratory and the field (Waddington 1953; Aubret & Shine 2009), it remains to be shown whether it can account for broad patterns of phenotypic diversity across entire adaptive radiations. Furthermore, our ignorance of the underlying molecular mechanisms has hampered our ability to incorporate phenotypic plasticity into models of evolutionary processes. In this issue of Molecular Ecology, Parsons et al. (2016) take a significant step in filling these conceptual gaps making use of cichlid fishes as a powerful study system. Cichlid jaw and skull morphology show adaptive, plastic changes in response to early dietary experiences (Fig. 1). In this research, Parsons et al. (2016) first show that the direction of phenotypic plasticity aligns with the major axis of phenotypic divergence across species. They then dissect the underlying genetic architecture of this plasticity, showing that it is specific to the developmental environment and implicating the patched locus in genetic assimilation (i.e. a reduction in the environmental sensitivity of that locus in the derived species).
Bilateral Ophthalmic Artery Dissecting Aneurysms Presenting with Recurrent Epistaxis

We present a rare case of bilateral expanding traumatic pseudoaneurysms of the ophthalmic arteries, due to a gunshot. The aneurysms presented with epistaxis. After a failure of conservative management, coil embolization of the aneurysms resulted in complete occlusion, with preservation of flow in the parent vessels.
How Does Adding an Emphasis on Socioscientific Issues Influence Student Attitudes About Science, Its Relevance, and Their Interpretations of Sustainability?

ABSTRACT A general consensus exists among the leaders of both developed and developing nations that their citizens should be scientifically literate. Therefore, it is important for educational systems to provide students with access to pertinent scientific knowledge, an appreciation for the scientific processes, and the ability to evaluate scientific claims. Students' attitudes toward science and its relevance can serve to nurture or impede the development of their science literacy. Some researchers have proposed that we can improve students' attitudes toward science and foster science literacy by emphasizing the connections between science and society. We sought to determine if the repeated and explicit exposure to socioscientific issues through the use of InTeGrate course materials would result in positive changes to students' attitudes about science and its relevance. We collected data on student attitudes using the revised Scientific Attitude Inventory and the Changes in Attitude about the Relevance o...

FEM-BEM analysis of tyre-pavement noise on porous asphalt surfaces with different textures

AbstractPavement surface characteristics such as surface texture and acoustic absorption play important roles in tyre-pavement interaction noise. The present study aims to investigate the effects of pavement surface texture and porous surface on tyre-pavement noise using a coupled modelling approach with finite element method–boundary element (FEM-BEM) analysis. A radial tyre model was first built using FEM, and tyre surface accelerations under the excitation from pavement texture were obtained from modal analysis. The radiation sound fields caused by tyre vibration were then solved using BEM for noise prediction. Texture profiles and sound absorption coefficients of different pavement surface types were considered in the analysis. The prediction results were calibrated and validated with the measurements reported in the literature. The results show that, with proper calibration, the proposed numerical model can predict sound pressure levels and overall noise with specific inputs of surface texture spectr...
Vesicular Anthracycline Accumulation in Doxorubicin-Selected U-937 Cells: Participation of Lysosomes

The U-A10 cell line, a doxorubicin-selected variant of human U-937 myeloid leukemia cells, exhibits a redistribution of anthracyclines into a expanded vesicular compartment. The acidic nature of this compartment was confirmed by vital staining with a pH sensitive dye, LysoSensor yellow/blue DND-160. Identification of the vesicular compartment was performed by immunofluorescence analysis. Staining for the LAMP-1 and LAMP-2 antigens showed that the vesicles are enlarged lysosomes that are eccentrically placed near the nucleus of U-A10 cells. By contrast, the expression of the multidrug resistance-associated protein and the P-glycoprotein was observed predominately on the plasma membrane of the drug-resistant cells. The accumulation of daunorubicin into cellular compartments was quantified using radiolabeled drug. Exposing cells to 3[H]-daunorubicin and then isolating intact nuclei showed that nuclei from U-A10 cells accumulated twofold to threefold less anthracycline than nuclei from U-937 cells. However, when nuclei were isolated first and then exposed to 3[H]-daunorubicin, little difference in net nuclear drug accumulation was detected. Cytoplasts prepared from U-A10 and U-937 cells were exposed to 3[H]-daunorubicin to measure cytoplasmic drug accumulation. At external daunorubicin concentrations of 100 ng/mL or higher, cytoplasts from U-A10 cells accumulated significantly more daunorubicin than cytoplasts from U-937 cells. Moreover, studies with the lysosomotropic agent chloroquine showed that U-A10 cells accumulated twofold more chloroquine and showed twofold enhanced sensitivity to this agent as compared with parental U-937 cells. Fluorescence microscopy showed that chloroquine affects vesicular anthracycline sequestration in U-A10 cells with an associated increase in daunorubicin nuclear fluorescence. Although chloroquine did not alter anthracycline cytotoxicity in parental cells, it restored daunorubicin and doxorubicin sensitivity to U-A10 cells. Taken together, these studies demonstrate that U-A10 cells exhibit a redistribution of the lysosomal compartment. The trapping of drug into an expanded acidic vesicular compartment results in decreased nuclear drug accumulation and decreased cytotoxicity. Lysosomotropic agents, such as chloroquine, warrant further study as modulators of this acquired drug-resistance phenotype.
Novel Findings in Bone Biology: Impact on Bone Health for Women

The maintenance of bone integrity throughout life is critical for minimizing the risk of debilitating fractures, which most frequently occur in those with low bone mass (osteopenia) and frank osteoporosis. Bone dynamically adapts to mechanical stresses placed on it, as with increased exercise, but this adaptation may be modified by changes in circulating estrogen, altered oxidative status, and nutritional factors. This review addresses novel findings of the last decade as they affect bone health in women. Specific topics discussed include the negative impact of low energy availability due to prolonged caloric restriction, the surprising role of estrogen receptor-alpha in bone mechanotransduction, and how oxidative stress may be an important mechanism contributing to bone loss with aging and estrogen insufficiency.
Introgression in maize

The principal characteristics of maize and its two relatives, teosinte and Tripsacum are described. The manifestations of the introgression of teosinte into maize determined from experimental cultures can be recognized in prehistoric maize from Guatemala, Mexico, and the southwestern United States. This introgression, which began at least 2,000 years ago, is still proceeding in Mexico where maize and teosinte commonly grow in the same fields and hybridize frequently. Evidence is presented of the direct introgression of Tripsacum in several races of maize of South America. The introgression of teosinte and Tripsacum has contributed to the evolution of maize through gene recombination, mutagenic effects, and various types of heterotic phenomena. The role of introgression in the improvement of maize is discussed.
Measuring expressivity between ontology models

In this paper, we describe an ontology evaluation methodology that measures the expressivity difference between two similar ontology entities. An ontology entity can be an ontology model, class, or property. In this methodology, an entity is considered more expressive if it contains more relevant axioms than the other. In measuring the expressivity, the methodology takes into account all the components that make up the entity and all the axioms within it. The proposed methodology is based on an abstract ontology representation that we formally define in this paper. Moreover, the methodology has been validated using two case studies with a fragment of one of these cases studies shown here as an example.
ELLIPTIC PHASE BOUNDARIES BETWEEN NEMATIC AND SMECTIC PHASES

Boundaries in the pressure-temperature plane between nematic and smectic phases that resemble arcs of ellipses have been reported. They can be fitted to a quadratic expansion of the change of Gibbs function with temperature and pressure, and it is suggested that the unmeasured parts of the boundaries are ellipses. Phases with hyperbolic boundaries can probably exist.
Optimal Cell Associations and Degrees of Freedom of Locally Connected Interference Networks with Message Passing Decoding

We study the problem of finding the optimal cell association as well as the per user degrees of freedom (puDoF) in large interference networks with local connectivity, where each base station is connected to the mobile terminal with the same index as well as $L$ following mobile terminals. In order for a base station transmitter to transmit the message desired by a mobile receiver in the downlink, or for a base station receiver to decode the message transmitted by a mobile transmitter in the uplink, we have the necessary condition that the base station has to be associated with the mobile terminal. We assume that each mobile terminal can only be associated with $N_{c}$ base stations. The association constraint reflects a rate-limited backhaul network as well as potential handshaking overhead. We restrict our attention to cooperative zero- forcing schemes in the downlink and message passing decoding in the uplink. In previous work, this problem was settled when considering only the downlink, as well as when considering only the uplink for the case when $N_{c}\geq\frac{L}{2}$ . Here, we settle the problem when only the uplink is considered by providing a converse proof for the case when $N_{c} . We then show how this result combined with existing results in the literature settles the uplink-downlink average puDoF problem when $N_{c}\leq\frac{L}{2}$ . We finally make progress towards solving the average puDoF problem when $N_{c} > L$ , by fixing the uplink scheme to the uplink-only optimal scheme and then finding the optimal downlink scheme, and consequently the average puDoF under this constraint.
Real Age: Red Blood Cell Aging During Storage

Background During cold storage, some red blood cell (RBC) units age more rapidly than others. Yet, the Food and Drug Administration has set a uniform storage limit of 42 days. Objectives of this review are to present evidence for an RBC storage lesion and suggest that functional measures of stored RBC quality—which we call real age—may be more appropriate than calendar age. Methods During RBC storage, biochemical substances and byproducts accumulate and RBC shape alters. Factors that influence the rate of degradation include donor characteristics, bio-preservation conditions, and vesiculation. Better understanding of markers of RBC quality may lead to standardized, quantifiable, and operationally practical measures to improve donor selection, assess quality of an RBC unit, improve storage conditions, and test efficacy of the transfused product. Results The conundrum is that clinical trials of younger versus older RBC units have not aligned with in vitro aging data; that is, the units transfused were not old enough. In vitro changes are considerable beyond 28 to 35 days, and average storage age for older transfused units was 14 to 21 days. Conclusions RBC product real age varies by donor characteristics, storage conditions, and biological changes during storage. Metrics to measure temporal changes in quality of the stored RBC product may be more appropriate than the 42-day expiration date. Randomized trials and observational studies are focused on average effect, but, in the evolving age of precision medicine, we must acknowledge that vulnerable populations and individuals may be harmed by aging blood.
Mitral valve repair for severe mitral valve regurgitation during left ventricular assist device implantation.

Abstract Background The management of severe mitral regurgitation (MR) at the time of left ventricular assist device (LVAD) implantation is controversial. We adopted an approach of systematic repair of severe MR at the time of LVAD implantation and report our experience. Methods We performed mitral valve repair (MVr) on 78 consecutive patients with severe MR undergoing LVAD implantation at our institution between 2013 and 2017. We compared data on these patients to 28 historical controls with severe MR from the immediate preceding period between 2011 and 2013 where the MR was not treated, using Cox modeling and propensity score methods. Median follow-up time was 17.7 months. Results Patients who underwent MVr were younger than those who did not (non-MVr group) (55 vs 63 years; P = .006), but otherwise had similar preoperative characteristics. The incidence of 30-day mortality (2.6% vs 3.6%; P = .78) and other early major adverse events was similar in both groups. At 3 months, no patient in the MVr group had more than mild MR compared with 7 patients (29%) in the non-MVr group (P Conclusions Concurrent MVr at the time of LVAD implantation can be done safely without increase in perioperative adverse events. MVr may be associated with better reduction in severity of MR and may have potential benefit in terms of reduction in readmissions for heart failure.

Symmetry-adapted real-space density functional theory for cylindrical geometries: Application to large group-IV nanotubes

We present a symmetry-adapted real-space formulation of Kohn-Sham density functional theory for cylindrical geometries and apply it to the study of large X (X=C, Si, Ge, Sn) nanotubes. Specifically, starting from the Kohn-Sham equations posed on all of space, we reduce the problem to the fundamental domain by incorporating cyclic and periodic symmetries present in the angular and axial directions of the cylinder, respectively. We develop a high-order finite-difference parallel implementation of this formulation, and verify its accuracy against established plane-wave and real-space codes. Using this implementation, we study the band structure and bending properties of X nanotubes and Xene sheets, respectively. Specifically, we first show that zigzag and armchair X nanotubes with radii in the range 1 to $5\phantom{\rule{0.16em}{0ex}}\mathrm{nm}$ are semiconducting, other than the armchair and zigzag type III carbon variants, for which we find a vanishingly small bandgap, indicative of metallic behavior. In particular, we find an inverse linear dependence of the bandgap with respect to the radius for all nanotubes, other than the armchair and zigzag type III carbon variants, for which we find an inverse quadratic dependence. Next, we exploit the connection between cyclic symmetry and uniform bending deformations to calculate the bending moduli of Xene sheets in both zigzag and armchair directions, while considering radii of curvature up to $5\phantom{\rule{0.16em}{0ex}}\mathrm{nm}$. We find Kirchhoff-Love type bending behavior for all sheets, with graphene and stanene possessing the largest and smallest moduli, respectively. In addition, other than graphene, the sheets demonstrate significant anisotropy, with larger bending moduli along the armchair direction. Finally, we demonstrate that the proposed approach has very good parallel scaling and is highly efficient, enabling ab initio simulations of unprecedented size for systems with a high degree of cyclic symmetry. In particular, we show that even micron-sized nanotubes can be simulated with modest computational effort. Overall, the current work opens an avenue for the efficient ab initio study of 1D nanostructures with large radii as well as 1D/2D nanostructures under uniform bending.

Sport Pricing Research: Past, Present, and Future

Despite its inclusion as one of the core Ps of the traditional marketing mix, research on sport pricing has been noticeably underrepresented in the sport marketing literature. In their content analysis of Sport Marketing Quarterly (SMQ), Peetz and Reams (2011) found only one article out of 346 in the journal which was topically categorized as sport pricing research. The largest percentage of published articles in the journal involves market research of spectators and/or participants. While some of these articles may include elements related to price, the vast majority overlook this critical element of marketing. However, technological innovation has forever altered how sport consumers evaluate products and services. Eor example, fi'om the consumer perspective, advanced Internet search tools have created a highly informed and highly price-sensitive consumer, partially because of the reduced cost of price-shopping (search cost). It has long been established that prices influence consumer attitudes and behaviors (Zeithaml, 1988). As such, as prices change, so too will consumer responses. Therefore, when researchers examine consumer attitudes and behaviors, they must consider the effect of prices, particularly as more demand-based and dynamic pricing strategies emerge.

Measurement Investigation on Acoustic Noise Caused by “Singing” Capacitors on Mobile Devices

Acoustic noise from mobile devices can be annoying for customers. Multilayer ceramic capacitors (MLCCs) soldered on printed circuit board (PCB) are known to be a main source of acoustic noise. The PCB in these devices feature hundreds of MLCCs. In this paper, a measurement methodology to identify the major vibrating MLCCs on board is presented. Laser Doppler vibrometer scanning result is used to find the dominant MLCC source. The correlation between board vibration and acoustic noise is confirmed with microphone probe. As a result of the piezoelectric properties of MLCCs, the root cause of the vibration is analyzed from an electric point of view. The problematic MLCCs are find to share the same power line which renders the same noise peaks as in the vibration and sound pressure measurements. After replacing the vibrating MLCCs with low acoustic noise MLCCs, the board clearly shows decreased level of vibration.
Secure Pattern-Based Data Sensitivity Framework for Big Data in Healthcare

With the exponential growth in the usage of electronic medical records (EMR), the amount of data generated by the healthcare industry has too increased exponentially. These large amounts of data, known as “Big Data” is mostly unstructured. Special big data analytics methods are required to process the information and retrieve information which is meaningful. As patient information in hospitals and other healthcare facilities become increasingly electronic, Big Data technologies are needed now more than ever to manage and understand this data. In addition, this information tends to be quite sensitive and needs a highly secure environment. However, current security algorithms are hard to be implemented because it would take a huge amount of time and resources. Security protocols in Big data are also not adequate in protecting sensitive information in the healthcare. As a result, the healthcare data is both heterogeneous and insecure. As a solution we propose the Secure Pattern-Based Data Sensitivity Framework (PBDSF), that uses machine learning mechanisms to identify the common set of attributes of patient data, data frequency, various patterns of codes used to identify specific conditions to secure sensitive information. The framework uses Hadoop and is built on Hadoop Distributed File System (HDFS) as a basis for our clusters of machines to process Big Data, and perform tasks such as identifying sensitive information in a huge amount of data and encrypting data that are identified to be sensitive.
Epidemic situation of animal plague in Gansu section of Golmud-Dunhuang railway

Objective To summarize and analyze the epidemic situation and trend of animal plague in plague foci of Gansu section of Golmud-Dunhuang railway, and provide basic reference for prevention and control of the plague. Methods The quantity of Marmot, rate of carrying fleas and flea index, plague serological and etiology detection results, the cross analyzing results of the railway section and the animal plague foci in Gansu section of Dolmud-Dunhuang railway (Akesai and Subei counties) from 2010 to 2015 were analyzed via the retrospective analysis method. Results The total average density of Marmot of Golmud-Dunhuang railway crossing area Akesai and Subei counties was between 0.23- 0.41 per hectare between 2010 and 2015. The rate of parasitic dye fleas in plague foci of Akesai was between 11.30% and 32.65%, body flea index was 0.74- 1.84. The rate of parasitic fleas dye fleas in plague foci of Subei was between 5.34% and 14.07%, the flea index was 0.25- 2.04. The etiology detection Marmot plague of Akesai and Subei was 2 049, 142 of them were positive, the positive rate was 6.93%; 592 groups of vector were detected, 44 of them were positive; the positive rate was 7.43%. There was no statistically significant difference between inspection bacteria rate and parasitic vector inspection rate of Marmot (χ2= 0.014, P > 0.05). Totally 1 719 serums of Marmot were tested, 132 of them were positive, the positive rate was 7.68%. Totally 421 serums of Canis lupus familiaris were detected, 61 of them were positive, the positive rate was 14.49%. There was statistically significant difference between the serum positive rate of Marmot and Canis lupus familiaris(χ2= 19.116, P < 0.05). Totally 17 animal foci were found along the railway in 2013, the nearest distance of the foci of bid from construction was 0.5 km, popular area was 61.02 km2, and 1 360 people were directly threatened. Conclusions Animal plague in Akesai and Subei regions along Golmud-Dunhuang railway is highly active. So we must take effective measures to guarantee the smooth progress of railway construction.

BIN1 protein isoforms are differentially expressed in astrocytes, neurons, and microglia: neuronal and astrocyte BIN1 are implicated in tau pathology

Identified as an Alzheimer’s disease (AD) susceptibility gene by genome wide-association studies, BIN1 has 10 isoforms that are expressed in the Central Nervous System (CNS). The distribution of these isoforms in different cell types, as well as their role in AD pathology still remains unclear. Utilizing antibodies targeting specific BIN1 epitopes in human post-mortem tissue and analyzing mRNA expression data from purified microglia, we identified three isoforms expressed in neurons and astrocytes (isoforms 1, 2 and 3) and four isoforms expressed in microglia (isoforms 6, 9, 10 and 12). The abundance of selected peptides, which correspond to groups of BIN1 protein isoforms, was measured in dorsolateral prefrontal cortex, and their relation to neuropathological features of AD was assessed. Peptides contained in exon 7 of BIN1’s N-BAR domain were found to be significantly associated with AD-related traits and, particularly, tau tangles. Decreased expression of BIN1 isoforms containing exon 7 is associated with greater accumulation of tangles and subsequent cognitive decline, with astrocytic rather than neuronal BIN1 being the more likely culprit. These effects are independent of the BIN1 AD risk variant. Exploring the molecular mechanisms of specific BIN1 isoforms expressed by astrocytes may open new avenues for modulating the accumulation of Tau pathology in AD.
Techno-economic assessment of Fischer-Tropsch synthesis and direct methane-to-methanol processes in modular GTL reactors

Abstract The aim of this study is to perform a techno-economic assessment of the Fischer-Tropsch synthesis (FTS) process in a microchannel reactor (MCR) to produce clean syncrude, and the Direct Methane to Methanol (DMTM) process in a compact plant footprint. The operational and economic performances of the two processes were modeled using the Aspen HYSYS v7.2. The operational performance parameters include products yield and the economic performance parameters include net present value (NPV), payback period (PBP) and internal rate of return (IRR). In addition, the effects of tailgas recycle ratios and water integration on the performances of the FTS process and the effect of methane recycle ratios on the performances of the DMTM were investigated. The simulation results showed that the unit cost of the DMTM process was sensitive to the methane recycle ratio, however, that of the FTS in MCR was less sensitive to the tailgas recycle ratios. In order to maintain an IRR > 10 %, the tail gas recycle ratio of the FTS in MCR had to be greater than 8 % and 30 %, at CO conversions of 80 % and 72 %, respectively, whereas in the DMTM process, a minimum methane recycle ratio of 60 % was required to achieve any profitability. In addition, the DMTM process appeared to have significantly higher net energy requirements per product yield when compared with those of the FTS in MCR process; however, both processes had higher energy requirements than those of conventional GTL technologies.
The National Library of Medicine Global Health Events web archive, coronavirus disease (COVID-19) pandemic collecting

Since January 30, 2020, when the World Health Organization declared the SARS CoV-2 disease (COVID-19) to be a public health emergency of international concern, the National Library of Medicine’s (NLM’s) Web Collecting and Archiving Working Group has been collecting a broad range of web-based content about the emerging pandemic for preservation in an Internet archive. Like NLM’s other Global Health Events web collections, this content will have enduring value as a multifaceted historical record for future study and understanding of this event. This article describes the scope of the COVID-19 project; some of the content captured from websites, blogs, and social media; collecting criteria and methods; and related COVID-19 collecting efforts by other groups. The growing collection—2,500 items as of June 30, 2020—chronicles the many facets of the pandemic: epidemiology; vaccine and drug research; disease control measures and resistance to them; effects of the pandemic on health care institutions and workers, education, commerce, and many aspects of social life; effects for especially vulnerable groups; role of health disparities in infection and mortality; and recognition of racism as a public health emergency.
The Possibility of Non-Euclidean Geometry

By the latter half of the 18th century the problem of deducing Postulate 5 from Neutral geometry had become, in mathematical circles, notorious. The Encyclopedist Jean le Rond d’Alembert called it (1759) “le scandale des elements de geometrie.”
Performance and perception: A preliminary examination of factors that may motivate students to bounce back

This work in progress (WIP) uses a mixed methods approach to consider how student satisfaction and performance affect academic resilience. A previous study introduced a sink, struggle, and soar model to quantitatively assess positive adaptation after a poor exam performance. An underlying assumption was that quantitative measures of performance would align with a student’s perception that they need to bounce back. However, some students who performed well by external standards still exhibited a strong desire to positively adapt, while other students who performed relatively poorly appeared unmotivated to adapt. In both scenarios, there appeared to be a mismatch between external measures of performance and internal perceptions. As part of an ongoing study of resilience, in this WIP we qualitatively and quantitatively examine student satisfaction with their performance. Preliminary data suggest that students with lower satisfaction than performance tend to focus on factors within their control when evaluating their performance. By contrast students with higher satisfaction than performance tend to attribute their low performance to external factors outside their control. As we continue to explore academic resilience, we hope that considering student satisfaction will provide insights into how to understand and help subpopulations in the classroom.

Equity Price Sensitivity and Expected Inflation

The authors specify a regression model for equity price sensitivity, and using this model identify several factors that determine how sensitive the equity price will be to changes in expected inflation. Results suggest that portfolio managers who believe expected inflation will increase significantly should tilt their portfolios toward low-yielding companies making significant investments in real assets and rely heavily on nominal contracts as a funding source.
On Salience-Sensitive Sign Classification in Autonomous Vehicle Path Planning: Experimental Explorations with a Novel Dataset

Safe path planning in autonomous driving is a complex task due to the interplay of static scene elements and uncertain surrounding agents. While all static scene elements are a source of information, there is asymmetric importance to the information available to the ego vehicle. We present a dataset with a novel feature, sign salience, defined to indicate whether a sign is distinctly informative to the goals of the ego vehicle with regards to traffic regulations. Using convolutional networks on cropped signs, in tandem with experimental augmentation by road type, image coordinates, and planned maneuver, we predict the sign salience property with 76% accuracy, finding the best improvement using information on vehicle maneuver with sign images.
Conceptualizing a Hypermedia Design for Language Learning

AbstractWith the rapid development of interactive technology, design models for hypermedia programs need also to evolve to “fit the technology” (Jonassen, 1988). The complexity of the hypermedia environment and human learning requires a framework for analysis that allows for flexibility, fluidity of events, and active interplay among elements in conceptualizing an interactive multimedia program. Operating from a theoretical perspective that carefully defines principles and concepts is the initial requirement. These concepts define the nature of the transformations which will be informed by the choice of thematic and spatial metaphor to orient the learner/teacher as they interact with the complex and sometimes confusing materials and large databases on interactive multimedia programs that use a hypermedia presentation approach.
Neuromodulation of the Cervical Dorsal Root Ganglion for Upper Extremity Complex Regional Pain Syndrome—Case Report

Objective Targeting the dorsal column, spinal cord stimulation (SCS) serves as a treatment method for complex regional pain syndrome (CRPS). Certain anatomical pain distributions are difficult to treat with traditional SCS, including the distal extremities. We present a case where stimulation of the dorsal root ganglion (DRG) was performed to treat CRPS in the distal upper extremity. Case Report A 43-year-old female underwent a right elbow arthroscopy with open reduction and internal fixation after sustaining a radial head fracture. Several months after her surgery, she experienced hyperesthesia, skin color changes, decreased range of motion, weakness distal to the right olecranon, and was diagnosed with CRPS. Aggressive physical therapy, nonsteroidal anti-inflammatory drugs (NSAIDs), and neuropathic agents provided mild relief. Open capsular release, hardware removal, and chondral debridement of the elbow did not provide alleviation. A diagnostic stellate ganglion block provided complete relief for two weeks. A therapeutic block allowed one day of relief, followed by recurrence of her symptoms. She underwent an SCS trial for treatment. Scar tissue in the posterior epidural space prevented catheter advancement, causing it to exit the C6 foramen. Incidental stimulation of the DRG occurred. Results On follow-up, patient reported >70% relief of her pain. On the visual analog scale, her maximal pain decreased from 8/10 to 4/10, with resolution of her initial symptoms and ability to perform all of her activities of daily living. Conclusion To our knowledge, this is the only reported case of utilizing DRG stimulation for CRPS of the distal upper extremity. Neuromodulation of the DRG appears to be an effective option for targeting painful areas in CRPS.
Major Depressive Disorder in Children and Adolescents: Clinical Trial Design and Antidepressant Efficacy

Major depressive disorder is a common, chronic, recurring, and disabling illness in children and adolescents. Epidemiologic data suggest that the mean age at onset for depression is becoming younger. Antidepressants are widely used in pediatric patients despite a relatively small evidence base from randomized, controlled studies. Compared with the adult population, there are very few controlled studies of antidepressants in children and adolescents, and the studies that have been conducted do not unambiguously demonstrate efficacy. These findings in general are contrary to clinicians' experiences with antidepressants in this population. The different factors associated with the outcome of antidepressant studies in children and adolescents are reviewed. Developmental issues in pediatric patients, such as age of puberty and maturity of neural circuitry, are considered in the context of failed clinical trials. Review of existing controlled trials demonstrates a wide variety in study methodology. Factors such as the study location, methods of patient recruitment, small sample sizes, inclusion/exclusion criteria, study design, and choice of outcome measures all influence the ability of a study to detect differences between an antidepressant and placebo. In the current atmosphere of increased concern about antidepressant side effects, including suicidality, it is increasingly important that clinicians who treat depressed children and adolescents make informed therapeutic decisions based on data from well-controlled clinical trials.
