Viewing Branch Brook Park: the history and future of landscape representation
Creators: name: Luo, Mouli
Publisher: name: No Publisher Supplied
Year: 2020

description: This thesis discusses how graphic representation is used in design, to make design decisions and inform visitors about park design, history and use. Using Branch Brook Park as an example, this thesis examines the initial historic representations of the Park, its documented changes over time, and representations that can expose the process to park visitors. This thesis found that technologies like Augmented Reality could facilitate visitor engagement in the landscape by providing cultural and historic context embedded in a digital/virtual platform. This approach could also initiate new ways for park administrators to engage in public outreach.

description: Blantyre City, located in Southern Region, Malawi, is characterized by high rates of malaria, HIV/AIDS, maternal mortality and an increasing burden of non-communicable diseases, such as cancer. Despite progress in reducing child mortality, children in Blantyre and Malawi are still dying of preventable causes such as neonatal complications, pneumonia and diarrhea. Malnutrition levels are also high. Additional challenges facing the health care delivery system in Blantyre include persistent stock-outs of drugs and medical supplies, insufficient essential medical equipment and an inadequate number of ambulances.

description: The Los Angeles Harbor at San Pedro with its natural advantages, and
the big development of these now underway, will very soon be the key to
the traffic routes of Southern California. The Atchison, Topeka, and Santa
Fe railway company realizing this and, not wishing to be caught asleep, has
planned to build a line from El Segundo to the harbor. The developments of
the harbor are not the only developments taking place in these localities
and the proposed new line is intended to include these also.

description: Over the last few decades, quantum chemistry has progressed through the development of computational methods based on modern digital computers. However, these methods can hardly fulfill the exponentially-growing resource requirements when applied to large quantum systems. As pointed out by Feynman, this restriction is intrinsic to all computational models based on classical physics. Recently, the rapid advancement of trapped-ion technologies has opened new possibilities for quantum control and quantum simulations. Here, we present an efficient toolkit that exploits both the internal and motional degrees of freedom of trapped ions for solving problems in quantum chemistry, including molecular electronic structure, molecular dynamics, and vibronic coupling. We focus on applications that go beyond the capacity of classical computers, but may be realizable on state-of-the-art trapped-ion systems. These results allow us to envision a new paradigm of quantum chemistry that shifts from the current transistor to a near-future trapped-ion-based technology.

description: With the installation by the Pacific Electric Railway
of a bus system in Pasadena to supplant most of its trolley
lines, the problem of the comparison of the costs of the two
systems naturally presented itself. The study here undertaken
was originally started as just a comparison of the motor
bus and Birney Safety Car, but as the work progressed it seemed
advisable to include the trolley bus as well - a method of
transportation that is comparatively new as far as development
is concerned, but which seems to be finding increasing favor
in the East.
Optically-Selected BLR-less Active Galactic Nuclei from the SDSS Stripe82 Database I: The Sample
Creators: name: Zhang, Xue Guang
Publisher: name: arXiv
Year: 2013
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: This is the first paper in a dedicated series to study the properties of the optically selected BLR-less AGNs (Active Galactic Nuclei with no-hidden central broad emission line regions). We carried out a systematic search for the BLR-less AGNs through the Sloan Digital Sky Survey Legacy Survey (SDSS Stripe82 Database). Based on the spectral decomposition results for all the 136676 spectroscopic objects (galaxies and QSOs) with redshift less than 0.35 covered by the SDSS Stripe82 region, our spectroscopic sample for the BLR-less AGNs includes 22693 pure narrow line objects without broad emission lines but with apparent AGN continuum emission $R_{AGN}>0.3$ and apparent stellar lights $R_{ssp}>0.3$. Then, using the properties of the photometry magnitude RMS ($RMS$) and the Pearson's coefficients ($R_{1, 2}$) between two different SDSS band light curves: $RMS_k>3\times RMS_{M_k}$ and $R_{1, 2}>\sim0.8$, the final 281 pure narrow objects with true photometry variabilities are our selected reliable candidates for the BLR-less AGNs. The selected candidates with higher confidence levels not only have the expected spectral features of the BLR-less AGNs, but also show significant true photometry variabilities. The reported sample at least four-times enlarges the current sample of the BLR-less AGNs, and will provide more reliable information to explain the lack of the BLRs of AGNs in our following studies.

Aryan Mundus and Sexual Inversion: Eliot's Edition of Nightwood
Creators: name: Vandenburg, Margaret
Publisher: name: Columbia University
Year: 1998
Subjects: Literature
Gender identity
Sex role

description: Despite its notorious sexual politics, Djuna Barnes's Nightwood gained considerable literary respectability when T. S. Eliot endorsed the first American edition with his Introduction. The presiding dean of Modernist letters at Faber and Faber in London, Eliot could distinguish even obscure writers with a single stroke of his editorial pen. Though his decision to publish Djuna Barnes's wildly subversive Nightwood suggests that an antic disposition lurked beneath his studied propriety, he expurgated several of the manuscript's most transgressive episodes, thus diminishing the redemptive role of sexual inversion in the novel. Eliot admits in his Introduction that “it took me, with this book, some time to come to an appreciation of its meaning as a whole”, but his editorial deletions indicate he overlooked the symbolic significance of inversion as the antithesis of Aryan essentialism in the manuscript. With uncanny prescience, Nightwood forecasts the nightmare of Nazi genocide and gendercide, creating a Parisian underground of expatriate inverts in exile from the deadly cultural “hygiene” of fascism. Analysis of the deleted manuscript passages restores the full force of Barnes's antifascist polemic in which inversion ultimately wins the day.
The multivariate Charlier polynomials as matrix elements of the Euclidean group representation on oscillator states

description: A family of multivariate orthogonal polynomials generalizing the standard (univariate) Charlier polynomials is shown to arise in the matrix elements of the unitary representation of the Euclidean group E(d) on oscillator states. These polynomials in d discrete variables are orthogonal on the product of d Poisson distributions. The accent is put on the d=2 case and the group theoretical setting is used to obtain the main properties of the polynomials: orthogonality and recurrence relations, difference equation, raising/lowering relations, generating function, hypergeometric and integral representations and explicit expression in terms of standard Charlier and Krawtchouk polynomials. The approach is seen to extend straightforwardly to an arbitrary number of variables. The contraction of SO(3) to E(2) is used to show that the bivariate Charlier polynomials correspond to a limit of the bivariate Krawtchouk polynomials.

description: This report details the work of a Spring 2011 Advanced Urban Planning Studio at Columbia University. Running between January - May 2011, students examined the challenges of regional planning for the inter-municipal Consortium of Leste Fluminense (CONLESTE) in response to Petrobras'Rio de Janeiro Petrochemical Complex (Comperi). Comperij is a megadevelopment project whose physical size and projected economic and social impacts are unprecedented in the region and in Latin America as a whole. The studio course included collaboration with the multiple stakeholders active in the project, including national, state and municipal government actors, Petrobras and other members of the private sector as well as international organizations and academic institutions. The stdio's engagement in te project joined the work of these actors, most of whom have been involved since the announcement of Comperj in 2006. This report offers recommendations to the different stakeholders for improving collaboration in regional planning for the reshaping of space and socio-economic dynamics in the region in manners that leverage Comperj as a catalyst to bring about greater environmental sustainability, social equity, and regional prosperity.
Blurry Access: A Bibliographic Analysis of Transparency Literature
Creators: name: Cruz Romero, Roberto
Publisher: name: Zenodo
Year: 2022

description: This review of the transparency literature has shown the evolution of the field through the prism of bibliographic and methodological data. In doing so, we have shed light into underlying disparities that go in line with arguments of structural problems and historical relations in socio-political contexts. We have highlighted the irony of the field in researching a topic that, due to determinants beyond the control of scholars (though OA policies may slowly generate a structural change), is in itself little transparent. The blurriness of the state of research in transparency and accountability helps us to address the overall debate of academic production in a critical manner, engaging with issues such as publishing and funding. These latter elements should suppose gateways for a wider diffusion of knowledge, yet they have seem to function as gatekeepers, undermining the duality we argue about – transparency as object and as medium. Though the first one may be well-developed and methodologically rich, the second one remains blurry in regard to the way knowledge is distributed.

description: Among the three branches of musicology-historical musicology, theory, and ethnomusicology it is the relationship between the last two that is most distant and tenuous.It is not difficult to see why. In terms of their subject matter, the theorist's domain (mainly Classical, Romantic, and twentieth century art music) is essentially a subdomain of the historical musicologist's (Western art music as a whole); and this, in turn, is non overlapping with the ethnomusicologist's (everything else). The more serious divide between ethnomusicology and theory, however, is in their philosophy and approach. This article discusses the rhythm and meter, and different aspects of African music through an analysis of Agawu's work.
Physical effects of gas envelopes with different extension on the collapse of a gas core

description: In this paper we study the gravitational collapse of a molecular hydrogen gas cloud composed of a core plus a gas envelope surrounding the core. We numerically simulate the collapse of four cloud models to take a glimpse to the time evolution of several dynamic variables, such as the angular momentum and the $aem$ ratio, as well as the ratios between the thermal and rotational energies with respect to the potential gravitational energy, denoted as $α$ and $β$, respectively, among others. We re-take those models introduced by Arreaga et.al (Astronomy and Astrophysics, {\bf Vol. 509}, (2010), pag. A96.) in the present paper in order to produce different outcomes of the collapsing cloud characterized in terms of the aforementioned dynamical variables. Such characterization was missing in the paper by Arreaga et.al (Astronomy and Astrophysics, {\bf Vol. 509}, (2010), pag. A96.), and here we show that the gas envelope extension effects on the collapsing core can be quantitatively compared.

Does Developmental Education Improve Labor Outcomes? Evidence from Two States.

Subjects: Community college students--Education
Community colleges

description: Nationally, about two thirds of community college students are referred to developmental education. Thus far, research on the effectiveness of developmental education has focused on students’ academic outcomes; in this paper, we examine the economic consequences of developmental education for students. Using longitudinal student-unit record data from two large community college systems linked to wage record data, we estimate the labor market returns to developmental credits versus college-level credits for two cohorts of students who attended community college in North Carolina and Virginia. While both states’ implemented new placement exams and developmental education course structures and curricula beginning in 2012, during the time period under study, both states’ developmental education programs and policies were fairly traditional and similar to those of other states nationwide. We find that, in both states, earning developmental reading and writing credits led to an increase in earnings, which is primarily attributed to an increased likelihood of employment. These findings suggest that earning developmental English credits may represent an improvement in academic literacy skills that are valuable in the labor market and improve individuals’ employability. In contrast, in both states, developmental math credits had negative impacts on earnings. That is, the opportunity costs associated with developmental math credits, particularly for those assigned to the lowest levels of the developmental math (and thus to the longest course sequences), tended to outweigh the potential labor market value these credits may bring. The negative impact of developmental math coursework on wages provides support for nationwide efforts to shorten the long-sequence structure of developmental mathematics, and to teach math skills that are applicable to students’ real-world needs.

description: Recent work on Ultra Long Period Cepheids (ULPCs) has suggested their usefulness as a distance indicator, but has not commented on their relationship as compared with other types of variable stars. In this work, we use Fourier analysis to quantify the structure of ULPC light curves and compare them to Classical Cepheids and Mira variables. Our preliminary results suggest that the low order Fourier parameters of ULPCs show a continuous trend defined by Classical Cepheids after the resonance around 10 days. However their Fourier parameters also overlapped with those from Miras, which make the classification of long period variable stars difficult based on the light curves information alone.

description: Rebleeding is a frequent complication of peptic ulcer bleeding (PUB). The associated prognosis remains rather unclear because previous studies generally also included non-ulcer lesions. We aimed to identify predictors for rebleeding; clarify the prognostic consequence of rebleeding; and develop a score for predicting rebleeding. Nationwide cohort study of consecutive patients presenting to hospital with PUB in Denmark from 2006–2014. Logistic regression analyses were used to identify predictors for rebleeding, evaluate the association between rebleeding and 30-day mortality, and develop a score to predict rebleeding. Patients with persistent bleeding were excluded. Among 19,258 patients (mean age 74 years, mean ASA-score 2.4), 10.8% rebled, and 10.2% died. Strongest predictors for rebleeding were endoscopic high-risk stigmata of bleeding (Odds Ratio (OR): 2.12 [95% Confidence Interval (CI): 1.91–2.36]), bleeding from duodenal ulcers (OR: 1.87 [95% CI: 1.69–2.08]), and presentation with hemodynamic instability (OR: 1.55 [95% CI: 1.38–1.73]). Among patients with all three factors (7.9% of total), 24% rebled, 50% with rebleeding failed endoscopic therapy, and 23% died. Rebleeding was associated with increased mortality (OR: 2.04 [95% CI: 1.78–2.32]). We were unable to develop an accurate score to predict rebleeding. Rebleeding occurs in ∼10% of patients with PUB and is overall associated with a two-fold increase in 30-day mortality. Patients with hemodynamic instability, duodenal ulcers, and high-risk endoscopic stigmata are at highest risk of rebleeding. When rebleeding occurs in such patients, consultation with surgery and/or interventional radiology should be obtained prior to repeat endoscopy.

The present study focuses on the role of matrix metalloproteinases (MMPs) in a novel mouse model of MM-induced brain damage. The model is based on intracisternal infection of BALB/c mice with a serogroup C Neisseria meningitidis strain. Mice were infected with meningococci and randomised for treatment with the MMP inhibitor batimastat (BB-94) or vehicle. Animal survival, brain injury and host-response biomarkers were assessed 48 h after meningococcal challenge. Mice that received BB-94 presented significantly diminished MMP-9 levels (p

description: Genomic translocation events frequently underlie cancer development through generation of gene fusions with oncogenic properties. Identification of such fusion transcripts by transcriptome sequencing might help to discover new potential therapeutic targets. We developed TRUP (Tumor-specimen suited RNA-seq Unified Pipeline) (https://github.com/ruping/TRUP), a computational approach that combines split-read and read-pair analysis with de novo assembly for the identification of chimeric transcripts in cancer specimens. We apply TRUP to RNA-seq data of different tumor types, and find it to be more sensitive than alternative tools in detecting chimeric transcripts, such as secondary rearrangements in EML4-ALK-positive lung tumors, or recurrent inactivating rearrangements affecting RASSF8.

description: There are currently no comparative data on the efficacy and safety of vedolizumab and ustekinumab in ulcerative colitis (UC) after anti-TNF therapy fails. We retrieved the full datasets of two observational, multicentre, retrospective studies of patients with UC for whom anti-TNF therapy failed and the patients were then treated with either vedolizumab or ustekinumab. The outcomes included steroid-free clinical remission, clinical remission, treatment persistence, colectomy, hospitalization, and serious and infectious adverse events. Propensity scores weighted comparison was applied. In total, 121 patients were included in the vedolizumab group and 97 were included in the ustekinumab group. At week 14 and week 52, in the weighted cohort, no difference was found between vedolizumab and ustekinumab for steroid-free clinical remission (OR = 0.55 [0.21–1.41], p = .21 and 0.94 [0.40–2.22], p = .89, respectively). There was no difference between vedolizumab and ustekinumab for secondary outcomes such as clinical remission, hospitalization, UC-related surgery, treatment persistence and serious and infectious adverse events. In patients with UC for whom anti-TNF therapy failed, no difference was found between vedolizumab and ustekinumab after propensity scores weighted comparison. Further studies are required to determine predictive factors of the efficacy of both biological agents.
Shifts in research priorities in Latin America and the Caribbean (LAC) during COVID-19 times

description: Science has, since the start of the COVID-19 pandemic, never looked so important to the everyday lives of people everywhere. The characterization of the virus; development of tests for infection; therapeutics to reduce the severity of the disease; information infrastructure to track the spreading; use of epidemiological models to predict the consequences of interventions; and the development of vaccines—all are dependent on scientific expertise and capability. Most countries have benefited from the pre-existence of a strong scientific and technical research base to this pandemic. The scientific community in LAC also responded massively to the pandemic. Between 2020-2021 COVID-19 related papers represented 6% of all COVID-19 related research in the World and between 2 and 3% of total scientific output (all areas) in the region. Before 2020, we could only identify in WoS 135 papers related to “coronavirus” by LAC authors. In 2020-2021 we identified 5302 COVID-19 related publications in WoS (40x more). In comparison, the topic with the second highest growth rate between 2018-2019 and 2020-2021 is “Microplastics” which increased 109% (1x) between periods.We identified the 141 researchers from LAC that were very prolific (5 or more pubs) in publishing COVID-19 related research publications in 2020-2021 and represented around 14% of total COVID-19 in the region. Overall, we found that the research areas where the most productive COVID-19 LAC researchers came from were highly related and relevant for COVID-19 (e.g. “Virology - Tropical Diseases”, “Assisted Ventilation”, “Immunology”, and “HIV”). This indicates that, as expected, when a new crisis emerges the scholars better able to produce new knowledge related to an emergent issue are the ones closer to the research space of that new research area. We found some exceptions that made large switches in their research areas (e.g. “Sports Science”, “Obstetrics & Gynecology”), which also reveals that the scientific community has sufficient flexibility to shift attention rapidly to major issues if there are clear incentives. Most of these switches were done without significantly sacrificing research effort on other research areas. Some notable exceptions include “Sports Science”, “Assisted Ventilation” and “Stem Cell Research”, that loss more than 25% of their publications in 2018- 2019.
Cantilena and Antiphon: Music for Marian Services in Late Medieval England
Creators: name: Lefferts, Peter M.
Publisher: name: Columbia University
Year: 1990
Subjects: Music

description: One of the most important contributions to studies of medieval music in recent years was made by Ernest Sanders as editor of volume two of English Music for Mass and Offices (volume XVII in the series Polyphonic Music of the Fourteenth Century). Sanders was particularly responsible for the editions of a large proportion of the surviving repertoire of polyphonic cantilenas, a major genre in terms of numbers of pieces and inherent musical value that heretofore has received little attention in the musicological literature, aside from Sanders's own contributions. The cantilena holds a place in the fourteeth-century English polyphonic repertoire roughly equivalent to that of the votive antiphon in the fifteenth century, though it is a much less familiar and less widely traveled genre. Stylistically, cantilenas form a complex category of works, but one that has nonetheless a clearly defined core.

description: The relationships between galaxies of intermediate stellar mass and moderate luminosity active galactic nuclei (AGNs) at 110^42.3 erg s^-1 disappear from the blue cloud/green valley where they were hosted predominantly by star-forming systems with disk and irregular morphologies. These results are even clearer when the rest-frame colors are corrected for dust reddening. At z~2.2, the ultraviolet spectra of active galaxies (including two Type 1 AGNs) show possible gas outflows with velocities up to about -500 km s^-1 that are not observed neither in inactive systems at the same redshift, nor at lower redshifts. Such outflows indicate the presence of gas that can move faster than the escape velocities of active galaxies. These results suggest that feedback from moderately luminous AGNs (logL_X<44.5 erg s^-1) played a key role at z>~2 by contributing to outflows capable of ejecting part of the interstellar medium and leading to a rapid decrease in the star formation in host galaxies with stellar masses 10

description: RNA sequencing (RNA-seq) is the current gold-standard method to quantify gene expression for expression quantitative trait locus (eQTL) studies. However, a potential caveat in these studies is that RNA-seq reads carrying the non-reference allele of variant loci can have lower probability to map correctly to the reference genome, which could bias gene quantifications and cause false positive eQTL associations. In this study, we analyze the effect of this allelic mapping bias in eQTL discovery. We simulate RNA-seq read mapping over 9.5 M common SNPs and indels, with 15.6% of variants showing biased mapping rate for reference versus non-reference reads. However, removing potentially biased RNA-seq reads from an eQTL dataset of 185 individuals has a very small effect on gene and exon quantifications and eQTL discovery. We detect only a handful of likely false positive eQTLs, and overall eQTL SNPs show no significant enrichment for high mapping bias. Our results suggest that RNA-seq quantifications are generally robust against allelic mapping bias, and that this does not have a severe effect on eQTL discovery. Nevertheless, we provide our catalog of putatively biased loci to allow better controlling for mapping bias to obtain more accurate results in future RNA-seq studies.

description: In contrast to the neutral population cycles of the deterministic mean-field Lotka--Volterra rate equations, including spatial structure and stochastic noise in models for predator-prey interactions yields complex spatio-temporal structures associated with long-lived erratic population oscillations. Environmental variability in the form of quenched spatial randomness in the predation rates results in more localized activity patches. Population fluctuations in rare favorable regions in turn cause a remarkable increase in the asymptotic densities of both predators and prey. Very intriguing features are found when variable interaction rates are affixed to individual particles rather than lattice sites. Stochastic dynamics with demographic variability in conjunction with inheritable predation efficiencies generate non-trivial time evolution for the predation rate distributions, yet with overall essentially neutral optimization.

description: Exposure to perinatal anxiety affects disease susceptibility in offspring but studies on the association between perinatal anxiety and gene polymorphisms are lacking. This study aimed to elucidate the interaction between perinatal anxiety and polymorphisms in antioxidant defense and innate immunity genes on the development of respiratory tract infections (RTIs) during early infancy. Trait anxiety levels in 440 women were assessed by the State-Trait Anxiety Inventory during late gestation. The occurrence of RTIs, including bronchiolitis, during the first year of life was assessed by parent-reported doctor diagnosis. Polymorphisms in glutathione S-transferase P-1 (GSTP1, rs1695) and CD14 (rs2569190) were genotyped using the TaqMan assay. Copy number variations of GSTT1 were measured by real-time polymerase chain reaction. Exposure to high levels of perinatal anxiety increased the risk of bronchiolitis in the first year of life (adjusted odds ratio [aOR], 1.30; 95% confidence interval [CI]: 1.00–1.80), in particular among children with the AG + GG genotype of GSTP1 or the GSTT1 null genotype (aOR 3.36 and 2.79). In infants with the TC + CC genotype of CD14, high levels of perinatal anxiety were associated with an increased risk of upper RTI, lower RTI, and bronchiolitis (aOR 2.51, 4.60, and 4.31, respectively). Perinatal maternal anxiety levels affect the occurrence of bronchiolitis in offspring. The effect of perinatal anxiety on the occurrence of bronchiolitis during infancy was influenced by genetic polymorphisms in antioxidant defense and innate immunity genes.

description: In a conventional positron source driven by a few GeV electron beam, a high amount of heat is loaded into a positron converter target to generate intense positrons required by linear colliders, and which would eventually damage the converter target. A hybrid target, composed of a single crystal target as a radiator of intense gamma--rays, and an amorphous converter target placed downstream of the crystal, was proposed as a scheme which could overcome the problem.This paper describes the development of an intense positron source with the hybrid target. A series of experiments on positron generation with the hybrid target has been carried out with a 8--GeV electron beam at the KEKB linac. We observed that positron yield from the hybrid target increased when the incident electron beam was aligned to the crystal axis and exceeded the one from the conventional target with the converter target of the same thickness, when its thickness is less than about 2 radiation length. The measurements in the temperature rise of the amorphous converter target was successfully carried out by use of thermocouples. These results lead to establishment to the evaluation of the hybrid target as an intense positron source.

description: There are two distinct etiologies of esophago-gastric junctional adenocarcinomas (EGJACs): one associated with extensive gastric mucosal atrophy (GA), resembling non-cardiac gastric cancers; and the other related to gastro-esophageal reflux disease, resembling esophageal adenocarcinoma. In this study, we investigated the associations between the visceral fat area (VFA) and EGJACs separately in the two subtypes of EGJACs, depending on the extent of background GA. Sixty-four consecutive patients with EGJACs (Siewert type 2) were enrolled from a population-based database in Akita Prefecture, Japan, between 2014 and 2019. Two age- and sex-matched healthy controls were randomly assigned to each EGJAC case. The extents of GA were evaluated endoscopically, and the VFA values were measured based on computed tomography images. Logistic regression analyses were performed to investigate the associations between EGJACs and the VFA. Study subjects were classified into 2 subgroups depending on the extent of endoscopic GA: 29 (45.3%) without and 35 (54.7%) with extensive GA. Multivariable regression analyses revealed that a VFA of ≥100 cm2 was significantly associated with EGJACs in subjects without extensive GA [odds ratio (95% confidence interval): 2.65 (1.08–6.54)], while there was no such association in subjects with extensive GA [odds ratio (95% confidence interval): 1.52 (0.60–3.83)]. The contribution of the VFA to the etiology of EGJACs seems to differ depending on the extent of background GA, with the VFA more prominently associated with EGJACs in subjects without extensive GA than in those with it, providing further rationale concerning the heterogeneous nature of EGJAC etiology.

description: The most stringent bounds on the absolute neutrino mass scale come from cosmological data. These bounds are made possible because massive relic neutrinos affect the expansion history of the universe and lead to a suppression of matter clustering on scales smaller than the associated free streaming length. However, the resulting effect on cosmological perturbations is relative to the primordial power spectrum of density perturbations from inflation, so freedom in the primordial power spectrum affects neutrino mass constraints. Using measurements of the cosmic microwave background, the galaxy power spectrum and the Hubble constant, we constrain neutrino mass and number of species for a model independent primordial power spectrum. Describing the primordial power spectrum by a 20-node spline, we find that the neutrino mass upper limit is a factor three weaker than when a power law form is imposed, if only CMB data are used. The primordial power spectrum itself is constrained to better than 10 % in the wave vector range $k \approx 0.01 - 0.25$ Mpc$^{-1}$. Galaxy clustering data and a determination of the Hubble constant play a key role in reining in the effects of inflationary freedom on neutrino constraints. The inclusion of both eliminates the inflationary freedom degradation of the neutrino mass bound, giving for the sum of neutrino masses $Σm_ν< 0.18$ eV (at 95 % confidence level, Planck+BOSS+$H_0$), approximately independent of the assumed primordial power spectrum model. When allowing for a free effective number of species, $N_{eff}$, the joint constraints on $Σm_ν$ and $N_{eff}$ are loosened by a factor 1.7 when the power law form of the primordial power spectrum is abandoned in favor of the spline parametrization.

description: We present a theory of the intrinsic anomalous Hall effect in a model of a doped Weyl semimetal, which serves here as the simplest toy model of a generic three-dimensional metallic ferromagnet with Weyl nodes in the electronic structure. We analytically evaluate the anomalous Hall conductivity as a function of doping, which allows us to explicitly separate the Fermi surface and non Fermi surface contributions to the Hall conductivity by carefully evaluating the zero frequency and zero wavevector limits of the corresponding response function. We show that this separation agrees with the one suggested a long time ago in the context of the quantum Hall effect by Streda.

description: Les collections ostéologiques sont un outil indispensable à toute étude archéozoologique. Néanmoins, bon nombre d’archéozoologues travaillant dans le domaine de l’archéologie préventive n’ont pas accès quotidiennement à une ostéothèque digne de ce nom du fait, notamment, de la répartition inégale des principales collections de comparaison sur le territoire national. Ainsi, à partir de 2016, le service archéologique du Grand Reims a mené une réflexion dans le but de constituer une ostéothèque plus étoffée avec la nécessaire mise en place d’une chaîne opérationnelle allant de l’acquisition du cadavre animal à sa préparation ostéologique.
description: Osteological collections are an indispensable tool for any archaeozoological study. Nevertheless, many archaeozoologists working in preventive archaeozoology don’t have daily access to an osteological collection worthy of the name, mainly due to the fact that main comparative collections are unevenly distributed throughout the country. Since 2016, the archaeological service of “Grand Reims” has been thinking about how to build up a more extensive osteological collection, requiring the implementation of an operational chain from the acquisition of the animal’s corpse to its osteological preparation.

description: The Linda Vista Bridge spans the Arroyo Seco about a
quarter of a mile above the Colorado Street Bridge, but
serves an entirely different territory; as there is no road
between there on the west bank. Los Angeles, Hollywood, and
several of the beach cities can be reached by the way of
the Colorado Street Bridge. The Linda Vista Bridge carries
the traffic to the northwest of Pasadena, that is, Flintridge, Linda Vista, Montrose, Sunland. After leaving the
bridge, the road follows the west bank of the Arroyo almost
to the mouth of the canyon; then to the west along the
foot of the mountains and into the San Fernando Valley.
