The characters of love: the case of “The Time Traveler’s Wife”

The Characters of Love is the title of a 1960 book by John Bayley, in which the author argued that love is a condition of a character, in so far it enables the writer to develop an interest in other personalities and explore them. In a period when literature was accused of paying attention primarily to the writer’s own consciousness, making it the centre of characterisation, and becoming, as a result, increasingly solipsistic and self-referential, Bayley set out to criticise this mode and encourage alternative approaches. In this article, I will borrow Bayely’s polysemic term to make a different point with reference to The Time Traveler’s Wife (2005) 1. I will argue that in this novel the characters are only too exclusively characters of love: love is at once the novel’s theme, plotting device, and a crucial aspect of characterization. What is lacking is an independent background that transcends the characters conceived in this way. The result is a different form of solipsism and self-referentiality. The story fails to fill out the narrative space, create a vivid reality, or raise questions about the ways in which this reality relates to ordinary life. These issues are closely related to the model of romantic love the story chooses to endorse, which will, therefore, be examined in some detail.
NT security in an open academic environment

Stanford Linear Accelerator Center (SLAC) was faced with the need to secure its PeopleSoft/Oracle business system in an academic environment which only has a minimal firewall. To provide protected access to the database servers for NT-based users all over the site while not hindering the lab's open connectivity with the Internet, we implemented a pseudo three-tier architecture for PeopleSoft with Windows Terminal Server and Citrix MetaFrame technology. The client application and Oracle database were placed behind a firewall, and access was granted via an encrypted link to a thin client. Authentication in the future will be through two-factor token cards. NT workstations in the business system unit were further secured through switched network ports and an automated installation process that included SMB signing and disabling LM Authentication in favor of NTLMv2. The hardened workstations then accessed the business system through the Citrix Secure ICA client. How these security measures affected our mixed environment (Windows9x, Samba, Transarc AFS clients, Pathworks, developers, researchers) is discussed.
Fish Consumption Patterns and Mercury Advisory Knowledge Among Fishers in the Haw River Basin.

Background Fish consumption has numerous health benefits, with fish providing a source of protein as well as omega-3 fatty acids. However, some fish also contain contaminants that can impair human health. In North Carolina, the Department of Health and Human Services has issued fish consumption advisories due to methylmercury contamination in fish. Little is known about local fishers' consumption patterns and advisory adherence in North Carolina. Methods We surveyed a consecutive sample of 50 fishers (74.6% positive response rate) who reported eating fish caught from the Haw River Basin or Jordan Lake. They provided information on demographic characteristics, species caught, and the frequency of local fish consumption. Additionally, fishers provided information on their knowledge of fish consumption advisories and the impact of those advisories on their fishing and fish consumption patterns. Results The majority of participants were male (n = 44) and reported living in central North Carolina. Catfish, crappie, sunfish, and large-mouth bass were consumed more frequently than other species of fish. Of the fishers surveyed, 8 reported eating more than 1 fish meal high in mercury per week, which exceeds the North Carolina advisory recommendation. Most participants (n = 32) had no knowledge of local fish advisories, and only 4 fishers reported that advisories impacted their fishing practices. Limitations We sampled 50 fishers at 11 locations. There is no enumeration of the dynamic population of fishers and no way to assess the representativeness of this sample. Conclusions Additional outreach is needed to make local fishers aware of fish consumption advisories and the potential health impacts of eating high-mercury fish, which may also contain other persistent and bioaccumulative toxins.
ORNITHISCHIAN DINOSAURS AND THE ORIGIN OF BIRDS.

The class Aves is an important constituent of the modern vertebrate fauna but the origin of birds is far from clear. One reason for this is that birds are poorly represented in the fossil record. This is especially true for the Triassic and Jurassic periods during which the group must have originated and developed (Fig. 1). Fortunately one early genus, the Upper Jurassic Archaeopteryx, is represented by two complete individuals from the fine-grained Solenhofen limestone of Bavaria, Germany. The associated impressions of feathers with both individuals shows that Archaeopteryx was definitely a bird, but the skeleton (Fig. 2B) shows a mosaic of reptilian and avian features. Modern birds also show certain features in their anatomy that justifies their description as "feathered reptiles" or, more specifically, as "feathered archosaurs." The archosaurs or ruling reptiles include the crocodiles, the two groups of dinosaurs (ornithischians and saurischians) that dominated the Mesozoic terrestrial scene and the pterodactyls or flying reptiles (Fig. 1). These four groups of higher archosaurs probably originated independently sometime in the Triassic from different lines of thecodonts, the basal archosaurian stock (Fig. 1). It is generally assumed that birds were derived from a fifth line of thecodonts somewhat like the facultatively bipedal Euparkeria (Fig. 2D) from the Lower Triassic of South Africa. According to Heilmann (1916, 1926) this active thecodont took to the trees to become an arboreal "Proavis" that developed gliding as an aid to jumping between branches. Heilmann (1916, 1926) concluded that birds and dinosaurs had completely separate origins from within the thecodonts and that any similarities were the result of parallelism and convergence. These conclusions have been accepted by most workers (e.g. de Beer, 1954, 1964; Boker, 1927; Ewer, 1965; Simpson, 1946; Steiner, 1917; Swinton, 1958, 1960, 1964; Tucker, 1938). However, I consider that the unique resemblance in the form of the pubis of ornithischians and birds (see below) may indicate a closer relationship between these two groups. The purpose of this paper is to review various features relevant to this problem and, in addition, to show that the arboreal "Proavis" was probably derived from a cursorial ground-living biped.

What Are You Going to Do, Talk Me to Death? Exploring the Narrative State in Interactive Entertainment.

We present a case study of narrative in an interactive game environment exploring how motivating text is used to create a narrative state in the mind of the player. This state in turn lends meaning to subsequent actions. We examine a set of text blocks from the game that tell a coherent, static story over a small play area and discuss the functions that text serves and the techniques used to accomplish them. We use this as a platform to explore how the narrative state might be varied to give insight into a more interactive narrative experience.
Epidemiologic evidence for the role of indoor tobacco smoke as an initiator of human breast carcinogenesis.

Earlier research suggested an appreciable latent period between the time of exposure to indoor tobacco smoke and the detection of breast cancer. A close relationship was found in the U.S. between state breast cancer mortality from 1978 through 1981 and state cigarette sales from 1950 through 1954 (R = 0.64, p less than 0.001). The correlation declined for sales in subsequent years but remained highly significant until 1970, but not thereafter. Thus, it appears that the role of indoor tobacco smoke in breast carcinogenesis is that of an initiator and/or an early-stage promoter in the process that leads after 15 to 30+ years to cancer. Trends in cigarette consumption from 1915 to 1965 paralleled breast cancer incidence in Connecticut women from 1935 to 1989. The 1953 and 1975 peaks in incidence were related to 1930 and 1953 peaks in cigarette consumption, respectively, showing a 22.5-year latent period. The drop in cigarette sales in the mid-1950s was followed by a surge to new highs in sales in the early 1960s in the great majority of the states. Approximately 23 years later, breast cancer incidence rates in the mid-1980s in all nine SEER populations are reflecting that surge in cigarette sales, rising to an all-time high in 1985. The earliest declines in breast cancer incidence should occur in New York and Connecticut, where cigarette sales have fallen most dramatically. By the year 2015, white women in the South, currently living with the men with the highest lung cancer rates in the U.S., are expected to show the highest breast cancer rates in the country.
User-Defined Types

This chapter provides an overview on the Structured Query Language's (SQL) structured user-defined types and the approaches to use them. The term “user-defined type” may seem to be pretty much self-explanatory. The use of type is, of course, meant to imply “data type,” that is, a data type that can be the type of some piece of data in the environment under discussion. In an SQL environment, this would normally be the data type of a column in a table, of an SQL variable in an SQL-invoked routine written in SQL, or of a parameter to an externally invoked SQL routine. SQL database systems have always had a selection of built-in data types that are available for use in applications. They range from types specified in the SQL standard (like INTEGER and SMALLINT, CHARACTER and CHARACTER VARYING, and DATE, TIME, and TIMESTAMP) to proprietary types defined by individual database system products (such as Sybase's SMALLMONEY and IMAGE types or Oracle's NUMBER and RAW types). SQL's object model is at once simpler than and more complex than Java language. Java is one of the most popular object-oriented programming languages today, and SQL's object facilities were quite consciously designed to be similar to Java's in many respects. The reasons for the greater complexity deal entirely with the difficulties caused by the fact that SQL manages persistent data that is described by equally persistent metadata.
Can Blood Pressure Responses to the Valsalva Maneuver Predict Orthostatic Hypotension? (S18.006)

OBJECTIVE: To evaluate if indices of cardiovascular adrenergic function derived from the Valsalva maneuver (VM) can predict orthostatic hypotension (OH). BACHGROUND: We recently demonstrated that the magnitude of late phase II and BP recovery time (PRT) following the VM are not only highly reproducible, but provide strong separation between groups of patients with different degrees of adrenergic impairment. It is unknown if and how well adrenergic indices derived from the VM can predict OH. DESIGN/METHODS: We randomly selected 29 subjects with normal cardiovascular adrenergic function, 28 with mild/moderate, and 29 with severe adrenergic failure based on routine laboratory testing. Indices were derived for each subject from two technically adequate VMs as follows: BP drop and pulse pressure compression during early phase II, BP recovery during late phase II, BP overshoot during phase IV, PRT, 50[percnt] PRT, and baroreflex sensitivity index. These indices were then correlated with the magnitude of orthostatic BP changes during head-up tilt. ROC curves were utilized to define cut-off values. RESULTS: All adrenergic indices showed a significant correlation with the magnitude of orthostatic BP changes during tilt. The by far strongest correlation was found for PRT (R²=0.70, p<0.0001); a cut-off value of 7 seconds had a sensitivity of 87[percnt] and specificity of 91[percnt] to predict an orthostatic BP drop of at least 20mmHg systolic and/or 10mmHg diastolic. The same cut-off value predicted an orthostatic BP drop of at least 30mmHg systolic and/or 15mmHg diastolic with a sensitivity of 97[percnt] and specificity of 87[percnt]. CONCLUSIONS: Parameters used to assess adrenergic function derived from the VM are associated with the magnitude of orthostatic BP change induced by head-up tilt. This association is strongest for PRT, which can be a useful indicator to predict the occurrence of OH during head-up tilt. Supported by NIH (K23NS075141, U54NS065736, UL1RR24150) and Mayo Funds.

Immunologic Changes in Critically III Patients After Anesthesia and Surgery

Summary Host defenses and immune competence are to some degree impaired in all patients by disease and the events of anesthesia and surgery. The effects of anesthesia per se are usually small in comparison, but are not without consequence, particularly for critically ill patients. It is hoped that heightened awareness combined with greater knowledge of these problems will improve our patients’ outcomes.
Negative emotional reactivity moderates the relations between family cohesion and internalizing and externalizing symptoms in adolescence

Abstract Lower family cohesion is associated with adolescent internalizing and externalizing problems. However, there are likely individual differences in youth's responses to family processes. For example, adolescents higher in negative emotional reactivity, who often exhibit elevated physiological responsivity to context, may be differentially affected by family cohesion. We explored whether youth's negative emotional reactivity moderated the relation between family cohesion and youth's symptoms and tested whether findings were consistent with the diathesis-stress model or differential susceptibility hypothesis. Participants were 651 adolescents ( M = 12.99 ± .95 years old; 72% male) assessed at two time points (Time 1, ages 12–14; Time 2, age 16) in Pittsburgh, PA. At Time 1, mothers reported on family cohesion and youth reported on their negative emotional reactivity. At Time 2, youth reported on their symptoms. Among youth higher in negative emotional reactivity, lower family cohesion predicted higher symptoms than higher family cohesion, consistent with the diathesis-stress model.
Preliminary Design of a Robotic System for Catching and Storing Fresh Market Apples

Abstract: This paper presents the preliminary design of a two-link planar manipulator for fresh market apple catching. Rather than use the harvesting manipulator to place picked apples in a storage container, the secondary system catches and stores apples at the point of fruit separation in order to minimize path length and improve cycle time. Monte Carlo simulations were used to select link lengths and joint limits. The design includes two low cost stepper motors and a vacuum assisted end-effector. After fabrication, laboratory studies were conducted to measure the system’s repeatability and validate the proof-of-concept. A conservative estimate of repeatability is 20 mm, which is within the catching end-effector’s effective workspace. During integrated system testing in the lab, the secondary system caught all harvested fruit. Likewise, the pick-and-catch technique resulted in an approximately 50 percent reduction in overall cycle time compared to the conventional pick-and-place method. Future work will include development of an end-effector prototype with soft elements to minimize fruit bruising.
Electrical and photonic off-chip interconnection and system integration

The ever increasing demand of bandwidth density at low energy budgets has motivated innovations in 2.5D and 3D integration. However, a comprehensive solution allowing electrical and photonic interconnection for short and long-range interconnects remains largely missing. Furthermore, thermal coupling between stacked chips remains a critical bottleneck before leveraging the true potential of 3D integration. Addressing some of these challenges, a large-scale interconnected system using a silicon bridging concept with optical and electrical I/Os which allows the coexistence of electrical and photonic interconnects, and a unique thermal isolation scheme for 3D integrated systems are discussed.
THE EFFECT OF A PHOSPHATE BUFFER AND MAGNESIUM CARBONATE ON QUALITY ATTRIBUTES OF COOKED GREEN VEGETABLES1

Color is one of the major problems in cooked green vegetables, particularly when held on a steam table prior to serving. To improve color retention, two compounds, a phosphate buffer and MgCO3, were added to frozen beans, peas, and spinach prior to cooking and during an hour long hold on a simulated steam table at 180 ± 5 F. Samples were taken after cooking in boiling water and thereafter at 20, 45, and 60 min intervals. Analyses were done for color, ascorbic acid, pH, and texture. Levels of phosphate buffer and MgCO3 used, improved color of vegetables without a disproportionate decrease in ascorbic acid as compared to the control. Since treated vegetables became excessively soft during a steam table bold of 20 min or more, these additives cannot be recommended to maintain color in cooked, whole frozen green vegetables. It would seem, however, that their addition to purees would be advantageous since texture is not an important consideration.
High temperature shape memory alloy Ni50.3Ti29.7Hf20 torque tube actuators

The torsional behavior of Ni-rich Ni50.3Ti29.7Hf20 (at%) high-temperature shape memory alloy tubes was investigated under pure torsion loading. Torque tubes with varying geometry including outer diameter, wall thickness, and length were subjected to constant-torque thermal cycling at stresses ranging from 0 to 500 MPa (0–175 N m). It was found that the wall thickness had a notable effect on the transformation temperatures where thick-walled tubes transformed at lower temperatures when compared to the thin-walled form. In all tube outer diameters, shear strains were found to be in the order of 6% obtained at stresses above 300 MPa. At lower stresses, little to no effect of wall thickness was observed, but the influence increased at higher stresses where thin-walled tubes generated approximately 2% less strain when compared to the solid forms. Two-way shape memory effect was also evaluated after 20 cycles and was found to reach ~3% strain when cycled at high stresses.
MRI of patients with implanted cardiac devices

Cardiac implanted electronic devices (CIEDs) have historically been regarded as a contraindication for performing magnetic resonance imaging (MRI), limiting the availability of this exam for large numbers of patients who may have otherwise benefited from the unique diagnostic capabilities of MRI. Interactions between CIEDs and the magnetic field associated with MRI systems have been documented, and include potential effects on CIED function, lead heating, and force/torque on the generator. Several device manufacturers have developed "MR-Conditional" CIEDs with specific hardware and software design changes to optimize the device for the MR environment. However, a substantial body of evidence has been accumulating that suggests that MRI may be safely performed in patients with either conditional or nonconditional CIEDs. Institutional policies and procedures, including preexam screening and assessment by skilled electrophysiology personnel and intraexam monitoring, allow MRI to be safely performed in CIED patients, as evidenced by at least two, large multicenter prospective studies and multiple smaller, single-institution studies. Cross-departmental collaboration and a robust safety infrastructure at sites that perform MRI should allow for the safe imaging of CIED patients who have a clinical indication for the study, regardless of the conditionality status of the device.

The Monophyletic Plectomycetes: Ascosphaerales, Onygenales, Eurotiales

In this chapter, we discuss the Plectomycetes as a monophyletic group of ascomycete fungi including the traditional orders Ascosphaerales, Onygevales, Eurotiales, as well as their strictly mitosporic relatives. In its original usage, the term Plectomycetes referred to any of the ascomycetes that produced asci within a completely closed sexual structure (ascoma, pl. ascomata), often termed a cleistothecium (Gr. kleistos,closed; theke, case) (Malloch 1981). More recently, phylogenetic analyses based on DNA sequences have demonstrated that many, but not all, of the cleistothecial ascomycetes belong to a monophyletic clade, which has been named the Plectomycetes (Berbee and Taylor 1994). This chapter is about the fungi belonging to that clade, and the justification for this usage is discussed in detail in Section III. A list of recognized genera is given in Table 1.
Contextual effect in second language perception and production of Mandarin tones

Abstract A robust contextual effect is well documented in native tone perception and production but less well studied in non-native speech. The current study examined English-speaking learners’ Mandarin tone perception and production with varying preceding and following tones. Fifteen intermediate-level learners performed an Identification and a Reading task with disyllabic stimuli encompassing various tone combinations. The results revealed that the learners’ accuracy rates and error patterns varied in the initial and final position as well as in different tonal environments. For example, the learners predominantly misidentified T3 as T4 in the initial position when the following tone was T1, but rarely made such an error in the final position. In the Reading task, on the other hand, the learners frequently misproduced T3 as T2 in the final position, but often misproduced T2 as T3 in the initial position, especially when the following tone was T1. The learners’ overall accuracy and error rates in Identification correlated with those in Reading, indicating comparable tone perception and production abilities. However, there were some significant differences between perception and production with regard to T3. These findings suggest that the prosodic position and surrounding tones both have a significant effect on the learners’ performance with L2 tones, and that the effect differs in perception and production.
Recovery of xenon from air over ZIF-8 membranes

Continuous ZIF-8 membranes effectively separated air/Xe gas mixtures. These membranes showed air permeances as high as 3.94 × 10−8 mol m−2 s−1 Pa−1 and separation selectivities as high as 12.4 for an air/Xe molar feed composition of 9 : 1. These membranes separated air from Xe via molecular sieving, preferential adsorption, and diffusivity differences.
Characterization of the Gap Junction Protein Connexin56 in the Chicken Lens by Immunofluorescence and Immunoblotting

Results. Connexin56 translated in vitro showed a single band with an electrophoreuc mobility of approximately 66 kd. Multiple bands of 67 to 90 kd were detected in immunoblots of chicken lens homogenates using antibodies raised against a peptide from Cx56. Most, if not all, of these bands represented different phosphorylated forms of Cx56, because immunoreactive Cx56 was detected as a doublet of 65 to 67 kd after treatment of lens homogenates with alkaline phosphatase. Indirect immunofluorescence demonstrated diat Cx56 was localized at membrane appositions between lens fibers and bow region cells. Levels of Cx56 increased from embryonic days 4 to 15; thereafter, levels remained fairly constant until hatching, after which they declined. Before embryonic day 9, the slowest migrating bands were not as abundant as they were at later ages. After embryonic day 20, less Cx56 was observed by immunofluorescence in the nucleus than in the cortex; however, both regions had similar levels of Cx56 as measured by immunoblotting. The pattern of bands differed between die two lens regions, suggesting differential protein modification. Immunoreactive Cx56 bands of 35 to 38 kd were detected unless homogenates were prepared in die presence of ediylenediaminetetraacetic acid (EDTA). Cx56 was also detected in lentoid-containing primary cultures derived from chicken lens. Conclusions. Cx56 is a phosphoprotein. Its appearance and modification by phosphorylation, as detected by immunoblotting, correlate with lens fiber differentiation. Invest Ophthalmol VisSci. 1994;35:41O9-4117.
Aortic impedance and compliance in hypertensive rats.

We compared aortic impedance and compliance in normotensive control and hypertensive Wistar rats. Hypertension was induced by unilateral nephrectomy plus steroid and salt water administration. After at least 8 wk of sustained hypertension (tail-cuff systolic pressures greater than 172 mmHg), open-chest ascending aortic micromanometric pressures and electromagnetic flows were measured. We used a frequency-modulated pacing method to enhance the energy content of the pressure and flow signals at specific low frequencies and their multiples. Impedance spectra were calculated using both Fourier series and spectral analysis methods. Compliance was calculated from the low-frequency impedance moduli, assuming a windkessel model for the arterial system. During pentobarbital sodium anesthesia under baseline conditions, the hypertensive rats had higher total resistance (219,000 vs. 126,000 dyn.s.cm-5), higher characteristic impedance (7,334 vs. 5,377 dyn.s.cm-5), larger first zero crossing of impedance phase angle (13.9 vs. 10 Hz), larger ratio of backward to forward pressure waves (0.67 vs. 0.48), and lower compliance (0.00498 vs. 0.00720 ml/mmHg) than controls. The differences between the groups were eliminated when the blood pressures of the hypertensive rats were normalized by vasodilation with nitroprusside or when the control rats were made hypertensive by vasoconstriction with phenylephrine. Thus the hemodynamic alterations appear to be secondary to the increased blood pressure. These base-line differences and the responses to vasoactive drugs are similar to findings in humans, suggesting that this rat model is a good hemodynamic model of human hypertension.
My Music, Their Music, and the Irrelevance of Music Education

In the late 1980s, researchers in the Music in Daily Life Project at the State University of New York at Buffalo set out to interview people about music in their lives.1 No prescriptions were put on who could be interviewed, and the interview format was open-ended, beginning simply with the question, “What is music about for you?” Among the 150 people who participated was a cross section of the population of Buffalo: children and elders; men and women; students, artists, at-home parents, and blue- and white-collar workers; and Whites and people of color. On the whole, it was one of the first studies of its kind in the United States, providing a wide snapshot of American music—not as an historical genre to be learned, or as a professional lifestyle to ogle, but as a diverse and changing set of practices in people’s everyday lives squeezed between, and often given meaning by, family obligations, life crises, work deadlines, and school chores.
The Medical Management of Heart Failure

The management of chronic heart failure has two goals. One is to produce short-term relief of symptoms and improvement in quality of life. The other is to slow or halt the progressive process of cardiac and peripheral dysfunction in heart failure that leads to long-term disability and shortened life expectancy. The former strategy is confined to patients with symptoms of heart failure; this may include exertional intolerance, shortness of breath or orthopnea, peripheral edema, or fatigue. It is important to recognize that not all heart failure is accompanied by congestive symptoms. Furthermore, some symptoms of heart failure may be subtle, leading to a reduced quality of life without the usual overt manifestations of heart failure. Therapy aimed at slowing progression of the disease is applicable in patients without symptoms as well as in those with symptoms. Left ventricular (LV) dysfunction may long antedate overt symptoms of heart failure, and the progressive nature of this LV dysfunction can potentially be prevented by aggressive therapeutic efforts. Indeed, treatment of heart failure symptoms must be accompanied by aggressive attempts to prevent progression of the disease, because the presence of symptoms identifies a patient whose condition is likely to progress in the absence of aggressive intervention. We therefore divide the therapeutic approaches for heart failure into these two separate categories.
Proper Management of the Patient with a Malignant Colorectal Polyp

Polyps containing invasive carcinoma have the potential for lymph node metastasis. Certain histologic features can be used to predict which cancers are likely to have metastasized after endoscopic polypectomy and therefore will need further surgical reduction. Management decisions should be based on the risks of metastasis compared to the risk and benefit of surgical intervention.

A conceptual framework to approach conservation of Indian modernist heritage

ABSTRACT: Preservation community over the last fifty years have developed philosophical and technical competence in managing various cultural heritage. However, it is yet to come in terms with the challenges pertaining to Modernist architecture, the latest to come under the umbrella of ‘heritage'. Conserving Modernist Heritage involves many technical and philosophical challenges. Lack of recognition and protection, absence of a shared methodological approach, dearth of public appreciation, obsolescence in term of functionality, sustainability and adaptability are some of the challenges that needs to be tackled while dealing with built heritage of the Modernist era. The transplantation and development of modernist architectural principles in every country was deeply influenced by the socio-political and economic agenda of the country. Therefore, concepts of heritage conservation require to be flexible in interpretation and region specific with respect to Modernist heritage. A conceptual framework needs to be developed with full understanding of the socioeconomic, cultural and historical contexts of the region/country under study. This paper aims to develop a conceptual framework to determine appropriate conservation approach for Modernist Heritage in India. Modernist Heritage in India does not qualify the ‘age' criteria defined by heritage legislations of the country and hence is not protected by the government. With the loss of one of its most significant and iconic modernist landmark, the need for an immediate framework becomes indispensable in India to recognize and protect the remaining significant Modernist heritage resources. The paper is based on a systematic literature review of pertinent sources on concepts such as heritage value assessment, community engagement, authenticity and its association with Indian Modernist heritage. The paper deduces that in order to develop an approach to recognize and protect Modernist Heritage of India, a collective understanding is critical, which involves three key dimensions: established/ existing frameworks, experts and local community.

Imaging Approaches for Coronary Artery Anomalies: Purpose and Techniques

Comprehensive discussion of alternative techniques in imaging coronary artery anomalies (CAAs) in different diagnostic scenarios. At primary screening, intramural course essentially correlates with stenosis and clinical repercussion in some types of CAAs. Potential clinical aims in imaging patients with CAAs may be primary screening, severity evaluation, preoperative planning, and postoperative follow-up. Appropriate techniques are echocardiography, magnetic resonance imaging, computed tomography angiography, and intravascular ultrasound (IVUS). Rarely, IVUS may be needed in patients with potentially serious CAAs and has unique advantages and limitations. IVUS data are essential for in-depth knowledge of mechanisms of coronary dysfunction (exercise-related dynamic stenosis of variable severity) and for indicating interventional treatment. In adolescents or adults, intramural course of an anomalous coronary artery is the only important feature accompanied by stenosis of potential severity and is especially relevant in patients with a high-risk status (elite sport athletes, military recruits).
TCT-779 An Updated Meta-Analysis of Radial Versus Femoral Access for Percutaneous Intervention in the Context of Aggressive Bleeding Avoidance Strategies

Recent meta-analyses of randomized clinical trials (RCTs) have shown that in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI), transradial access (TRA) improves the mortality rate compared with transfemoral access (TFA), possibly because of decreased
CHAPTER 1 – Complexity

Publisher Summary Complexity has been defined as a large number of things that interact in a nonsimple way (Simon, 1965). Some would argue that quantity is not a requirement for complexity. This concept lies at the heart of general systems theory. Finite, partly emotional, and partly logical minds that are windows for seeing the world have complexities of their own. These internal complexities must themselves be understood because it is believed that construction of reality is relative to physical and behavioral makeup. This chapter explores the nature of complexity itself and some of the current problems facing society. Systems ideas have been applied in a diversity of real life problems ranging from food distribution to medicine. Still the practical value of systems thinking in such areas has been questioned and criticized.
High Resolution (0.0005 cm 1 ) Spectroscopy of Carbon Disulfide with Interleaved Mid-IR Frequency Combs

We measured the high-resolution absorption spectrum of the carbon disulfide (CS 2 ) v3v+1 band using a broadband dual-comb subharmonic OPO system. The 14.5-MHz effective resolution was achieved by interleaving eight comb spectra with 115-MHz intermodal spacing.

The Best-Loved Self

In this chapter, I shine the spotlight on the teacher’s best-loved self. I begin by tracing my journey to discovering the unnamed phenomenon in my own and others’ research programs. My ongoing search eventually led to the lexis, the best-loved self, an apt phrase Schwab used to signify that teachers are more than the subject matter they teach. I then interweave concepts and ideas from other researchers who arrived at similar understandings. After that, I dive deeply into my own research program and examine expressions of the best-loved self in the experiential accounts of Daryl, Bernadette, Helen, and Anna Dean, together with Ashley Thomas, Shi Tan, and other teachers who have appeared in my published works. Lastly, I capture expressions of my best-loved self in the context of my professional life.
Inductance Dual Model and Control of Multiphase Coupled Inductor Buck Converter

This paper presents an inductance dual model for designing coupled inductors in multiphase buck converters. The model is derived as a topological dual of the reluctance model of a multiphase coupled inductor, yielding an inductance-based equivalent circuit with simplified equations for evaluating the transient and steady state performance. The model clearly relates the magnetic geometry to a lumped circuit model, allowing visualization of coupling relationships and magnetic flux in SPICE. The model is conducive to state space and transfer function analysis. The dynamic equations of the M-phase coupled inductor buck converter are derived. It is revealed that the duty ratio to output voltage transfer function of a multiphase coupled inductor buck converter is equivalent to that of a single-phase buck converter. The inductance dual is leveraged to design a programmable coupled inductor that modulates the center leg reluctance to improve the control bandwidth.

The Dynamics of the Alfvénic Oval

Abstract The auroral oval is a well-established concept, introduced more than five decades ago. The Alfvenic oval, on the other hand, is a very recent concept, which has been revealed in both observational and numerical studies. This is the first review of the global Alfvenic oval, while also defining primary, secondary and tertiary layers of the Alfvenic oval. The focus lies on the large-scale dynamic properties of the global Alfvenic oval in relation to the AE index, substorm phases, storm phases and solar wind/IMF conditions. Statistical data recorded above and below the nominal auroral acceleration region are reviewed, together with results from global simulation studies that have reproduced the Alfvenic oval. The Alfvenic oval's relation to the auroral oval is also reviewed. This review demonstrates that the Alfvenic oval is well enough defined and investigated to give it its name, and it demonstrates that our understanding allows for the prediction of the Alfvenic oval under various conditions.
Statistical sparsity-based learning for ultra-wideband radar signal reconstruction

This work presents a novel method to reconstruct ultra-wideband radar signals over their entire bands when only a portion of the spectrum is available. The inherent sparse configuration of sensing radars is exploited to develop a robust wideband synthesizing framework. The proposed approach consists of the following two steps: 1) A radar signal model is developed which allows for a sparse representation of the target’s signature over wide bandwidths. 2) A flexible statistical model is introduced to solve the sparse model of Step 1 in a Bayesian framework. By imposing Gamma-Gaussian sparsity promoting priors on the target’s signature, the model improves the sensing accuracy. In addition, by introducing a Gaussian mixture model of noise, any non-deterministic density of noise or jamming can be accurately approximated. This significantly increases robustness in complex environments. The proposed approach is verified through the development of an ultra-wideband (12–110 GHz) radar system consisting of canonical-spherical targets. Monte Carlo simulations are carried out to compare the performance of the proposed statistical method when the data missing rate is 25% with other methods in the literature. It is shown that the proposed model has closed-form solutions and is robust to complex environments with satisfying performance. As the noise distribution violates the single Gaussian assumption, other relevant methods in the literature fail to recover the model with a large RMS error (< 0.50). In contrast, our method has a maximum RMS of only 0.11.

"Through the Beautiful Red": The Use of the Color Red as the Triple-Goddess in Sylvia Plath's Ariel

The color red appears in nineteen of the Ariel poems. These nineteen "red poems" and their placement in the collection create a pattern of purification and rebirth from which a single character emerges. 1 The first four red poems deal with the female body. The next eight red poems connect the female body with the body of mother earth, specifically in night or pre-dawn settings. The next six of the nineteen red poems are poems that deal with forgetfulness, the death of the physical body, and purging of personal history in order to be reborn. The last red poem, "Stings," completes the cycle of female rebirth and purification in these Ariel poems. Red is Sylvia Plath's "Triple-Goddess." To understand the Triple-Goddess, we must first look back to Robert Graves's The White Goddess. Despite the controversy surrounding Graves's research, there is no doubt about his influence on Sylvia Plath. 2 Susan Bassnett writes in Sylvia Plath: An Introduction to the Poetry that "Graves' book appealed both because of its celebration of poetry and of the idea of the poet but also because of his investigations into the mythical sources of the creation of poetry" (58). While connecting obscure myths, beginning with the legend of Jason, the Argonauts and the Golden Fleece, Graves aims to unite different religious cults through matriarchy. Graves states his thesis: "the language of poetic myth anciently current in the Mediterranean and Northern Europe was a magical language bound up with popular religious ceremonies in honour of the Moon-goddess, or Muse, some of them dating from the Old Stone Age, and that this remains the language of true poetry—'true' in the nostalgic modern sense of 'the unimprovable original, not as a synthetic substitute' (Graves 9-10) and claims the "function of poetry [as] religious invocation of the Muse" (Graves 14). Graves mythologizes all women into the Triple-Goddess
