Introduction: The Ingredients of a Masterpiece

Subjects: Music

description: I believe that the study of music can justifiably include the study of any aspect of musical behavior, including the study of the teaching of music as well as the study of the teaching about music. With this in mind, some time ago I had the idea that it would be an interesting departure for Current Musicology to examine the teaching of music survey courses, with particular attention paid to "masterpieces" courses-of the type that constitutes the music component of Columbia's undergraduate Core Curriculum. I wanted views from outside Columbia-indeed, from outside the research university setting-as well, so I solicited articles from scholar-administrators at a conservatory and at a liberal arts college. I am therefore pleased to present, in this special section of Current Musicology #65, the viewpoints of Peter Rojcewicz, from The Juilliard School in Manhattan, and of Sean Williams, from The Evergreen State College in Olympia, Washington. Annalisa Swig Poirel, an early music scholar here at Columbia, provides a look at the issue from within the research university itself; my own contribution makes mention of some of the unspoken, and too often unexamined, musical "givens" that contribute to the production, dissemination, and consumption of the Masterpieces of Western Music.
CoRoT target HD 51844: a delta Scuti star in a binary system with periastron brightening

description: The star HD 51844 was observed in CoRoT LRa02 as a Seismo target which turned out to be an SB2 system. The 117 days long light curve revealed delta Scuti pulsation in the range of 6 to 15 d^{-1} where four frequencies have amplitudes larger than 1.4 mmag and a rich frequency spectrum with amplitudes lower than 0.6 mmag. Additionally, the light curve exhibits a brightening event recurring every 33.5 days with a maximum of 3 mmag and a duration of about 5 days. Thus, this star can be considered as a heartbeat candidate. The radial velocities from spectroscopy confirmed an eccentric binary system with nearly identical masses and physical parameters. The brightening event of the light curve coincides with the maximum radial velocity separation showing that the brightening is in fact caused by tidal distortion and/or reflected light. One component displays large line profile variations, while the other does not show significant variation. The frequency analysis revealed a quintuplet structure of the four highest-amplitude frequencies, which is due to the orbital motion of the pulsating star.

On the monodromy problem for the four-punctured sphere

description: We consider the monodromy problem for the four-punctured sphere in which the character of one composite monodromy is fixed, by looking at the expansion of the accessory parameter in the modulus $x$ directly, without taking the limit of the quantum conformal blocks for infinite central charge. The integrals which appear in the expansion of the Volterra equation, involve products of two hypergeometric functions to first order and up to four hypergeometric functions to second order. It is shown that all such integrals can be computed analytically. We give the complete analytical evaluation of the accessory parameter to first and second order in the modulus. The results agree with the evaluation obtained by assuming the exponentiation hypothesis of the quantum conformal blocks in the limit of infinite central charge. Extension to higher orders is discussed.

title: CARDIAC EFFECTS OF OBESITY DURING PREGNANCY IN C57BL/6J MICE
Creators: name: Dudick, Kayla
Publisher: name: University of Kentucky Libraries
Year: 2020
Subjects: subject: FOS: Health sciences

description: Objective: Pregnancy requires profound cardiac and metabolic adaptation. Left ventricular (LV) mass is increased in response to pregnancy, but is not associated with cardiac damage. In contrast, obesity-mediated cardiac hypertrophy is pathological. Data from animal studies indicate dietary fatty acid composition may have a protective effect during states of extreme cardiac physiological adaptation. In contrast, aberrant cardiac metabolism is a hallmark of disease. Over a third of reproductive-age women in the United States are obese, but there is a paucity of data describing the effect of obesity on maternal cardiac adaptation to pregnancy. The objective of this study was to determine the effects of high-fat feeding during pregnancy on cardiac hypertrophy and metabolism in a mouse model of diet-induced obesity.

Methods/Results:Female C57BL/6J mice (8 weeks old) were fed a high fat (HF; 60% kcal from fat) or a control low fat (LF; 10% kcal from fat) diet for 8 weeks, then were either crossed with male mice to become pregnant (P) or remained non-pregnant (NP) controls. At gestational day 18, cardiac function was quantified by echocardiography in LF- and HF-fed P and NP females. On gestational 19 day, mice were euthanized for tissue collection. HF-fed females had significantly increased body weight compared to LF-fed controls, and body weight was increased in P compared to NP mice. In response to pregnancy, LF-, but not HF-fed, mice had significantly increased LV mass (P Acaa2, Acox1,and Acadl (genes regulated long-chain fatty acid oxidation) and Cpt1b (regulating fatty acid transport into the mitochondria) were upregulated with both HF-feeding and pregnancy. In contrast, Ehhadh, a gene regulating production of medium chain fatty acids during fatty acid oxidation, was increased in pregnant mice, but only in the LF mice, and the expression was significantly reduced in HF- compared to LF-fed pregnant mice.

Conclusions: Physiological cardiac hypertrophy in response to pregnancy was observed in LF-fed, but not HF-fed mice. In contrast, HF-fed pregnant mice had increased RWT compared to LF-fed pregnant mice. While fatty acid utilization was increased with HF-feeding and pregnancy, the expression of Ehhadh was reduced in HF- compared to LF-fed mice. Medium chain fatty acids are demonstrated in the literature to be protective against pathological cardiac remodeling in experimental animals. Taken together, these data suggest obesity may impair protective fatty acid utilization pathways in pregnancy to promote adverse cardiac remodeling.

description: Das Fotoalbum ist in besonderer Weise für die Problematisierung von Materialitätsfragen im
 Digitalen prädestiniert. Dass Alben Objekte sind, wird zwar nicht vergessen, bleibt aber in
 digitalen Bildarchiven weitgehend irrelevant, solange die darin enthaltenen Fotografien für
 Nutzer:innen abrufbar bleiben. Was einst Album war, wird in der Regel in Einzelbilder und
 Einzelseiten aufgelöst. Das steht im Kontrast zur eigensinnigen Materialität von Fotoalben.
 Ihre Strukturen werden nicht nur durch einzelne Bilder bestimmt, sondern durch die Logik
 des Verhältnisses der Bilder, ihre Abfolge, ihre Beschriftungen und ihre Diskontinuitäten.
 Dennoch bleibt der dreidimensionale Albumkörper, sozusagen das Nicht-Bild, im Digitalisat
 visuell in Form von Einband, Vorsatzblätter, Trennseiten, leere Seiten und Kordeln enthalten.
 Noch immer herrscht in der Forschung eine teils strenge Unterscheidung zwischen
 Archivobjekt und dessen Reproduktion, die sich auf Vorstellungen von Autor:innenschaft,
 Original und Aura stützt. Ausgehend von Beispielen aus der Praxis der Digitalisierung von Fotoalben aus dem
 Dissertationsprojekt geht der Beitrag der Frage nach, inwiefern eine Übersetzung der
 Materialität ins Digitale einen Wechsel in der Wahrnehmung auslöst. Besondere
 Aufmerksamkeit gilt dabei den oben genannten Nicht-Bildern. Wo beginnt das (digitale)
 Fotoalbum und wo hört es auf? Wie ändert die Digitalität unseren Umgang mit Fotoalben?
 Der Beitrag verfolgt dabei das Ziel, in zweierlei Hinsicht auf das Fotoalbum als
 vielversprechenden Forschungsgegenstand aufmerksam zu machen. Zum einen als Foto-
 Objekt, das durch seine Materialität seine Geschichte vergegenwärtigt und zum anderen vor
 dem Hintergrund von digitalen Technologien wie 3D und IIIF (International Image

description: Broadband coronagraphy with deep nulling and small inner working angle has the potential of delivering images and spectra of exoplanets and other faint objects. In recent years, many coronagraphic schemes have been proposed, the most promising being the optical vortex phase mask coronagraphs. In this paper, a new scheme of broadband optical scalar vortex coronagraph is proposed and characterized experimentally in the laboratory. Our setup employs a pair of computer generated phase gratings (one of them containing a singularity) to control the chromatic dispersion of phase plates and achieves a constant peak-to-peak attenuation below $1\cdot 10^{-3}$ over a bandwidth of 120 nm centered at 700 nm. An inner working angle of ~λ/D is demonstrated along with a raw contrast of 11.5 magnitudes at 2λ/D.

description: Only a subset of patients who enter stage 3 chronic kidney disease (CKD) progress to stage 4. Identifying which patients entering stage 3 are most likely to progress could improve outcomes, by allowing more appropriate referrals for specialist care, and spare those unlikely to progress the adverse effects and costliness of an unnecessarily aggressive approach. We hypothesized that compared to non-progressors, patients who enter stage 3 CKD and ultimately progress have experienced greater loss of renal function, manifested by impairment of metabolic function (anemia, worsening acidosis and mineral abnormalities), than is reflected in the eGFR at entry to stage 3. The purpose of this case-controlled study was to design a prediction model for CKD progression using laboratory values reflecting metabolic status. Using data extracted from the electronic health record (EHR), two cohorts of patients in stage 3 were identified: progressors (eGFR declined >3 ml/min/1.73m2/year; n = 117) and non-progressors (eGFR declined <1 ml/min/1.73m2; n = 364). Initial laboratory values recorded a year before to a year after the time of entry to stage 3, reflecting metabolic complications (hemoglobin, bicarbonate, calcium, phosphorous, and albumin) were obtained. Average values in progressors and non-progressors were compared. Classification algorithms (Naïve Bayes and Logistic Regression) were used to develop prediction models of progression based on the initial lab data. At the entry to stage 3 CKD, hemoglobin, bicarbonate, calcium, and albumin values were significantly lower and phosphate values significantly higher in progressors compared to non-progressors even though initial eGFR values were similar. The differences were sufficiently large that a prediction model of progression could be developed based on these values. Post-test probability of progression in patients classified as progressors or non-progressors were 81% (73% − 86%) and 17% (13% − 23%), respectively. Our studies demonstrate that patients who enter stage 3 and ultimately progress to stage 4 manifest a greater degree of metabolic complications than those who remain stable at the onset of stage 3 when eGFR values are equivalent. Lab values (hemoglobin, bicarbonate, phosphorous, calcium and albumin) are sufficiently different between the two cohorts that a reasonably accurate predictive model can be developed.

New Musicologies, Old Musicologies: Ethnomusicology and the Study of Western Music*
Creators: name: Stock, Jonathan P. J.
Publisher: name: Columbia University
Year: 1997
Subjects: Music

description: Ethnomusicology currently engages with the study of Western music in two principal ways. On the one hand, there are specific ethnomusicological studies that focus on aspects of Western musical traditions. Examples include Paul Berliner's analysis of improvisation in jazz (1994), Philip Bohlman's study of chamber music as ethnic music in contemporary Israel (1991), and the examinations of music schools and conservatories by Bruno Nettl (1995) and Henry Kingsbury (1988). These works, in and of themselves, offer explicit and direct indication of what an ethnomusicological approach to Western music involves and what manner of insights can be produced thereby. Second, and more diffusely, ethnomusicological research plays into the study of Western music through musicologists' adoption, adaptation, and application of ethnomusicological techniques and concepts: some musicologists have drawn from specific ethnographies of non Western musical traditions, and others have made recourse to the standard texts of ethnomusicological theory and practice (such as Merriam 1964 and Nettl 1983). This article discusses the recent diversification of traditional musicology and the serious consideration by musicologists of ethnomusicological theory and practice.

is to determine the efficiency and inefficiency in the operation of
the Bureau of Power and Light of Los Angeles, California, as it exists
at the present time. This will be more on the order of a government
investigation than a purely engineering thesis. An engineering thesis
consists or reports based on experiments and tests, etc., while the
present undertaking will consist of investigation of the facts concerning
the organization, operation and conduct of the business of the
Bureau of Power and Light. The facts presented were obtained from
several sources: (1) the writer's knowledge of the business; (2) books
written on municipal ownership; (3) reports published by the Bureau, and
(4) personal interviews with men connected with the organization. I
have endeavored to draw conclusions from the facts thus obtained, as to

description: Random walks are a primary means for extracting information from large-scale graphs. While most real-world graphs are inherently dynamic, state-of-the-art random walk engines failed to efficiently support such a critical use case. This paper takes the initiative to build a general random walk engine for dynamically changing graphs with two key principles: (i) This system should support both low-latency streaming updates and high-throughput batched updates. (ii) This system should achieve fast sampling speed while maintaining acceptable space consumption to support dynamic graph updates. Upholding both standards, we introduce Bingo, a GPU-based random walk engine for dynamically changing graphs. First, we propose a novel radix-based bias factorization algorithm to support constant time sampling complexity while supporting fast streaming updates. Second, we present a group-adaption design to reduce space consumption dramatically. Third, we incorporate GPU-aware designs to support high-throughput batched graph updates on massively parallel platforms. Together, Bingo outperforms existing efforts across various applications, settings, and datasets, achieving up to a 271.11x speedup compared to the state-of-the-art efforts.

Malaria--Economic aspects

description: Malaria is commonly associated with poverty. Macro-level estimates show strong links between malaria and poverty, and increasing evidence suggests that the causal link between malaria and poverty runs in both directions. However, micro-level (household and population) analyses on the linkages between malaria and poverty have often produced mixed results. The Gambia Malaria Indicator Survey (MIS) 2010/11 was carried out between November 2010 and January 2011. Laboratory-confirmed malaria and wealth quintiles were used to assess the association of socio-economic status and malaria infection in children and the general population. Simple and multiple logistic regressions and survey data analysis procedures, including linearized standard errors to account for cluster sampling and unequal selection probabilities were applied. Children (six to 59 months) from the second, third, fourth and richest quintiles were significantly less likely to have malaria compared to children from the poorest quintiles. Children (five to 14 years) from the fourth and richest quintiles were also significantly less likely to have malaria compared to those from the poorest quintiles. The malaria burden has shifted from the under-five children (six to 59 months) to children aged five to 14 years. Malaria prevalence was significantly higher in the Central River Region compared to the Upper River Region; and males bear the malaria brunt more than females. Children (six to 59 months) and children (five to 14 years) living in houses with poor walls, floors, roofs and windows were significant associated with higher prevalence of malaria. However, in the general population, only poor wall housing materials were associated with higher prevalence of malaria. Investments in strategies that address socio-economic disparities and improvements in the quality of housing could, in the long term, significantly reduce the malaria burden in the poorest communities.
Membrane potential based assay for SLC6A9 using HEK-293 SLC6A9 OE cells

description: FLIPR® membrane potential dye measures changes of charges across the cell membrane, upon activation of SLC6A9. The assay allows the detection of ion channel and transporter modulation by increasing or decreasing the fluorescent signal as cellular membrane potential changes. When cells are depolarized dye enters the cells, causing an increase in fluorescent signal, conversely, cells hyperpolarization results in dye exit and decreased fluorescence. The transport of glycine in glutamatergic synapse is carried out by SLC6A9, a Na+/Cl--dependent carrier molecule. The primary role of SLC6A9 is to maintain glycine concentrations below saturation level at postsynaptic NMDA receptors. It operates bidirectionally: it decreases synaptic glycine concentration when operates in normal mode and releases glycine from glial cells as operates in a reverse mode.

description: Individuals with extensive support needs, including those who have autism spectrum disorder and are classified as level 3 in the area of social communication, are more likely than same-age peers to display delays in age-appropriate social communication and engagement in activities. To address these issues, special education teachers, in collaboration with related-service providers, should create social communication and engagement objectives. Once objectives are identified, teachers can plan for and implement environmental arrangement (EA) strategies to promote these behaviors in a natural context. EA strategies are a long-standing approach to creating a communication-rich environment and can be used alone or paired with systematic teaching strategies. In addition, embedding opportunities for social communication and engagement within and across activities can be challenging and, as such, requires careful planning. Teachers can use a communication matrix to create a plan for addressing these social communication objectives throughout the school day.

description: Our aim was to study the light curve periodicity of the solar analogue V352 CMa and in particular show that the presence or absence of periodicity in low amplitude light curves can be modelled with the Continuous Period Search (CPS) method. We applied the CPS method to 14 years of V-band photometry of V352 CMa and obtained estimates for the mean, amplitude, period and minima of the light curves in the selected datasets. We also applied the Power Spectrum Method (PSM) to these datasets and compared the performance of this frequently applied method to that of CPS. We detected signs of a $11.7 \pm 0.5$ year cycle in in the mean brightness. The long-term average photometric rotation period was $7.24 \pm 0.22$ days. The lower limit for the differential rotation coefficient would be $|k| > 0.12$, if the law of solar surface differential rotation were valid for V352 CMa and the period changes traced this phenomenon. Signs of stable active longitudes rotating with a period of $7.157 \pm 0.002$ days were detected from the epochs of the light minima with the Kuiper method. CPS performed better than the traditional PSM, because the latter always used a sinusoidal model for the data even when this was clearly not the correct model.

description: Females of the solitary digger wasp tribe Philanthini, called the beewolves (Hymenoptera, Crabronidae), cultivate strains of symbiotic bacteria that belong to the genus Streptomyces in unique and highly specialized glands in their antennae. The glands consist of large reservoirs that are surrounded by numerous gland cell complexes (class III). The symbionts are cultivated inside the reservoirs and are probably provisioned with nutrients secreted from the surrounding glands and/or sequestered from the hemolymph. The wasp female delivers the bacteria into the subterranean brood cell prior to oviposition. Fully grown larvae take up the bacteria and apply them to their cocoon. There the bacteria produce several antibiotics that protect the wasp offspring against fungus infestation. Hitherto Streptomyces bacteria were detected in the antennae of 38 species of the Philanthini. However, a detailed morphological analysis of the antennal glands is only available for a few species. In order to shed light on the evolutionary history of the association between beewolf wasps and bacteria, we investigated the morphology of the antennal glands of another 14 Philanthus species from the Palearctic, Paleotropic, and Nearctic. We generated 3D-models of the glands based on serial semithin sections and/or micro-CT (μCT). Despite broad similarities in number and structure of antennal glands, the results revealed interspecific differences with regard to overall shape, complexity, and relative size of the reservoirs as well as the number of the surrounding gland cell units. Mapping the morphology of all species studied so far on the phylogeny (that parallels geographical distribution) revealed that related species share similarities in gland morphology, but there are notable differences between lineages. In particular, compared to the North American species the European and African species possess more complex gland structures with a higher number of gland cells. We discuss morphological, ecological, and physiological aspects and provide scenarios for the evolution of the antennal glands of the Philanthini as symbiont cultivation organs.

description: In an earlier paper it was argued that the conventional double-scaling limit of an O(N)-symmetric quartic quantum field theory is inconsistent because the critical coupling constant is negative and thus the integral representing the partition function of the critical theory does not exist. In this earlier paper it was shown that for an O(N)-symmetric quantum field theory in zero-dimensional spacetime one can avoid this difficulty if one replaces the original quartic theory by its PT-symmetric analog. In the current paper an O(N)-symmetric quartic quantum field theory in one-dimensional spacetime [that is, O(N)-symmetric quantum mechanics] is studied using the Schroedinger equation. It is shown that the global PT-symmetric formulation of this differential equation provides a consistent way to perform the double-scaling limit of the O(N)-symmetric anharmonic oscillator. The physical nature of the critical behavior is explained by studying the PT-symmetric quantum theory and the corresponding and equivalent Hermitian quantum theory.

description: The enormous fiscal pressures facing trauma centers may lead trauma centers to reduce nurse staffing and to make increased use of less expensive and less skilled personnel. The impact of nurse staffing and skill mix on trauma outcomes has not been previously reported. The goal of this study was to examine whether nurse staffing levels and nursing skill mix are associated with trauma patient outcomes. We used data from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample to perform a cross-sectional study of 70,142 patients admitted to 77 Level I and Level II centers. Logistic regression models were used to examine the association between nurse staffing measures and (1) mortality, (2) healthcare associated infections (HAI), and (3) failure-to-rescue. We controlled for patient risk factors (age, gender, injury severity, mechanism of injury, comorbidities) and hospital structural characteristics (trauma center status - Level I versus Level II, hospital size, ownership, teaching status, technology level, and geographic region). A 1% increase in the ratio of licensed practical nurse (LPN) to total nursing time was associated with a 4% increase in the odds of mortality (adj OR 1.04; 95% CI: 1.02-1.06; p = 0.001) and a 6% increase in the odds of sepsis (adj OR 1.06: 1.03-1.10; p
Older adults’ home- and community-based care service use and residential transitions: a longitudinal study

description: As Home-and Community-Based Services (HCBS), such as skilled nursing services or personal care services, have become increasingly available, it has become clear that older adults transit through different residential statuses over time. Older adults may transit through different residential statuses as the various services meet their needs. The purpose of this exploratory study was to better understand the interplay between community-dwelling older adults’ use of home- and community-based services and their residential transitions. The study compared HCBS service-use patterns and residential transitions of 3,085 older adults from the Second Longitudinal Study of Aging. Based on older adults’ residential status at the three follow-up interviews, four residential transitions were tracked: (1) Community-Community-Community (CCC: Resided in community during the entire study period); (2) Community-Institution-Community (CIC: Resided in community at T1, had lived in an institution at some time between T1 and T2, then had returned to community by T3); (3) Community-Community-Institution (CCI: Resided in community between at T1, and betweenT1 and T2, including at T2, but had used institutional services between T2 and T3); (4) Community-Institution-Institution (CII: Resided in community at T1 but in an institution at some time between T1 and T2, and at some time between T2 and T3.). Older adults’ use of nondiscretionary and discretionary services differed significantly among the four groups, and the patterns of HCBS use among these groups were also different. Older adults’ use of nondiscretionary services, such as skilled nursing care, may help them to return to communities from institutions. Personal care services (PCS) and senior center services may be the key to either support elders to stay in communities longer or help elders to return to their communities from institutions. Different combinations of PCS with other services, such as senior center services or meal services, were associated with different directions in residential transition, such as CIC and CII respectively. Older adults’ differing HCBS use patterns may be the key to explaining older adults’ transitions. Attention to older adults’ HCBS use patterns is recommended for future practice. However, this was an exploratory study and the analyses cannot establish causal relationships.

description: It is well known that any given density rho(x)can be realized by a determinantal wave function for N particles. The question addressed here is whether any given density rho(x) and current density j(x) can be simultaneously realized by a (finite kinetic energy) determinantal wave function. In case the velocity field v(x) =j(x)/rho(x) is curl free, we provide a solution for all N, and we provide an explicit upper bound for the energy. If the velocity field is not curl free, there is a finite energy solution for all N\geq 4, but we do not provide an explicit energy bound in this case. For N=2 we provide an example of a non curl free velocity field for which there is a solution, and an example for which there is no solution. The case $N=3 with a non curl free velocity field is left open.

Metabolic syndrome

description: Current smoking is associated with type 2 diabetes mellitus and impaired glucose tolerance but its association with the metabolic syndrome (metS), particularly with sufficiently sampled African American representation, has not been clearly established. To assess whether a) metS is associated with smoking; b) any increased risk of metS among smokers is independent of body mass index (BMI) compared with non-smokers; c) smoking status is differentially associated with the metS and its components across different ethnic groups. Cross sectional analysis of the Multi-Ethnic Study of Atherosclerosis (MESA) a community population-based sample free of cardiovascular disease. Current smokers (N = 769) had higher risk of metS (odds ratio [OR, 95% confidence interval]: 1.4, 1.1-1.7) versus never (reference, N = 2981) and former smokers (1.0, 0.8-1.1, N = 2163) and for metS components: high waist circumference (WC) (OR:1.9, 1.2-2.1), low high density lipoprotein cholesterol (HDL-C) (1.5, 1.3-1.8), elevated plasma triglycerides (TG) (OR:1.4, 1.2-1.7) as well as high C-reactive protein (CRP, an inflammatory marker) concentration (OR: 1.6,1.3-2.0) compared to never and former smokers after adjustment for BMI. A smoking status by ethnicity interaction occurred such that African American current and former smokers had greater likelihood of low HDL-C than White counterparts. Conclusions: This study found that smoking is associated with the metS and despite the lower BMI of current smokers the prevalence of low HDL-C, elevated TG and CRP is higher among them than among non-smokers. African Americans generally have higher HDL-C than Whites but smoking wipes out this advantage. Multi-Ethnic Study of Atherosclerosis (MESA) ClinicalTrials.gov Identifier: NCT00005487
The Colorado River - a Source of Water and Power for Los Angeles

description: The rapid growth and development of Los Angeles City
and County has been one of the phenomena of the present age. The
growth of a city from 50,600 to 576,000, an increase of over 1000%
in thirty years is an unprecedented occurrence. It has given rise
to a variety of problems of increasing magnitude.

Chief among these are: supply of food, water and shelter development of industry and markets, prevention and removal
of downtown congestion and protection of life and property.
These, of course, are the problems that any city must face.
But in the case of a community which doubles its population
every ten years, radical and heroic measures must often be
taken.
Membrane potential based assay for SLC5A7 using HEK-293 SLC5A7 OE cells

Subjects: Transport assay

description: FLIPR® membrane potential dye measures changes of charges across the cell membrane, upon activation of SLC5A7. The assay allows the detection of ion channel and transporter modulation by increasing or decreasing the fluorescent signal as cellular membrane potential changes. When cells are depolarized dye enters the cells, causing an increase in fluorescent signal, conversely, cells hyperpolarization results in dye exit and decreased fluorescence. SLC5A7 is a hemicholinium-3 (HC-3)-sensitive transporter that mediates choline uptake by pre-synaptic terminal with a stoichiometry of 1 Na+: 1 choline. Therefore, being this transport electrogenic, it is eligible to be studied using the Membrane Potential dye.

Orlando Innamorato di Matteo Maria Boiardo: rielaborato e reso in versione abbreviata per ragazzi/Orlando in Love: abridged and translated for young readers

Italian literature

description: Malory's Italian contemporary Matteo Maria Boiardo (1441-1494) brought together the epic Carolingian stories of the hero Roland and the Arthurian romances of the Breton cycle, thereby creating the new genre of the "romance epic. " His poem Orlando Innamorato (Orlando in Love) is populated with knights, damsels, giants, wizards,fairies, and monsters, in alternating episodes of love, magic, adventure, and warfare, sometimes told through the creative rewriting of classical texts such as Homer's Odyssey and Ovid's Metamorphoses. This 35,440 verse 'chivalric poem has never been adapted for young readers before, either in Italian or translation. This adaptation remains faithful to the fast-paced richness and playful flavor of the original. It also maintains Boiardo's technique of "entrelacement, weaving together various narrative threads in an alternating manner, while highlighting episodes that have a strong thematic coherence. Although Boiardo states that his goal is merely to entertain, his stories present positive and negative models of behavior which encourage loyalty, self-control, self-knowledge, perseverance, honesty, and a sense of responsibility to others. It is my  hope that this taste of Boiardo's poem will arouse in the reader the desire to read the complete romance epic, available in a superb translation by Charles S. Ross.

description: Spins of negatively charged nitrogen-vacancy (NV$^-$) defects in diamond are among the most promising candidates for solid-state qubits. The fabrication of quantum devices containing these spin-carrying defects requires position-controlled introduction of NV$^-$ defects having excellent properties such as spectral stability, long spin coherence time, and stable negative charge state. Nitrogen ion implantation and annealing enable the positioning of NV$^-$ spin qubits with high precision, but to date, the coherence times of qubits produced this way are short, presumably because of the presence of residual radiation damage. In the present work, we demonstrate that a high temperature annealing at 1000$^\circ$C allows 2 millisecond coherence times to be achieved at room temperature. These results were obtained for implantation-produced NV$^-$ defects in a high-purity, 99.99% $^{12}$C enriched single crystal chemical vapor deposited diamond. We discuss these remarkably long coherence times in the context of the thermal behavior of residual defect spins. [Published in Physical Review B {\bf{88}}, 075206 (2013)]
