Detection of CMB-Cluster Lensing using Polarization Data from SPTpol.

We report the first detection of gravitational lensing due to galaxy clusters using only the polarization of the cosmic microwave background (CMB). The lensing signal is obtained using a new estimator that extracts the lensing dipole signature from stacked images formed by rotating the cluster-centered Stokes QU map cutouts along the direction of the locally measured background CMB polarization gradient. Using data from the SPTpol 500  deg^{2} survey at the locations of roughly 18 000 clusters with richness λ≥10 from the Dark Energy Survey (DES) Year-3 full galaxy cluster catalog, we detect lensing at 4.

Sustaining the Lives of Art Objects.

This article explores the complex process of sustaining the lives of art objects and considers ways in which conservation efforts in art museums parallel cultural humility cultivation among health care professionals. Conservators and scientists at the Art Institute of Chicago grapple with a number of ethical questions that emerge when preserving and caring for objects with complicated histories and entangled networks of stakeholders. What follows is an examination of these issues in relation to objects in the Art Institute's collection and the larger histories of art museums and medicine.

What Do Warhol, Pollock, and Murakami Teach Us About AI in Health Care?

As with medicine, artistic practice has a historical relationship with technologies. As technology advances, artists and medical practitioners will struggle with the complexities of introducing artificial intelligence into pursuits that have long been defined as fundamentally human. How will intelligent mechanization continue to aid efforts in art and medicine, even as it complicates them? Which new dilemmas will arise as essentially human pursuits are ever more deeply aligned with the rise of thinking machines?

Southeast Atmosphere Studies: learning from model-observation syntheses.

Concentrations of atmospheric trace species in the United States have changed dramatically over the past several decades in response to pollution control strategies, shifts in domestic energy policy and economics, and economic development (and resulting emission changes) elsewhere in the world. Reliable projections of the future atmosphere require models to not only accurately describe current atmospheric concentrations, but to do so by representing chemical, physical and biological processes with conceptual and quantitative fidelity. Only through incorporation of the processes controlling emissions and chemical mechanisms that represent the key transformations among reactive molecules can models reliably project the impacts of future policy, energy and climate scenarios.

Measurement of emotional contagion using synchronization of heart rhythm pattern between two persons: Application to sales managers and sales force synchronization.

The purpose of this study was to measure emotional contagion, determine its direction, and compare the intensity between positive and negative contagion using the synchronization of heart rhythm pattern (HRP). A total of 64 undergraduate students (32 women and 32 men) participated in the experiment, and were randomly categorized as either leaders or followers. Followers were required to imitate the facial expression (happy and sad) of the leader (emotional contagion) or of a facial image (emotional non-contagion).

Bioinspired, Spine-Like, Flexible, Rechargeable Lithium-Ion Batteries with High Energy Density.

The rapid development of flexible and wearable electronics proposes the persistent requirements of high-performance flexible batteries. Much progress has been achieved recently, but how to obtain remarkable flexibility and high energy density simultaneously remains a great challenge. Here, a facile and scalable approach to fabricate spine-like flexible lithium-ion batteries is reported.

The Emergence and Persistence of Queerness: Conversing Through Visual Culture Within a Generation.

In this article, the authors explore the work of becoming queer within the Millennial generation. Collaborative in nature, their investigation turns to three key popular-culture texts of the 1990s-Will & Grace, Rent, and MTV's Spring Break-that were central to their then-emerging sense of self. Staged as an intragenerational conversation, the authors look to create space to unpack the connections, anecdotal by design, between popular texts and changing ideas of queer identity and community.

Recent molecular systematic studies of Cantharellus cibarius sensu lato have revealed previously unknown species in different regions of North America. This study investigates yellow chanterelles in the Midwest using phylogenetic analysis of three DNA regions: nuc rDNA internal transcribed spacer 2 (ITS2) and 28S sequences and translation elongation factor 1α gene (EF1α). This analysis reveals a locally common taxon Cantharellus chicagoensis sp.

The Colors of Keith Haring: A Spectroscopic Study on the Materials of the Mural Painting Tuttomondo and on Reference Contemporary Outdoor Paints.

To date, little attention has been given to the scientific investigation of modern and contemporary mural paintings. This paper reports on: (1) the in situ spectroscopic analyses of the mural Tuttomondo (1989) painted by Keith Haring (1958-1990) in Pisa (Italy); and (2) the laboratory characterization of acrylic paints produced by Caparol Italy GmbH & Co., the original supplier of paint materials to the artist for the mural.

B→πll Form Factors for New Physics Searches from Lattice QCD.

The rare decay B→πℓ^{+}ℓ^{-} arises from b→d flavor-changing neutral currents and could be sensitive to physics beyond the standard model. Here, we present the first ab initio QCD calculation of the B→π tensor form factor f_{T}. Together with the vector and scalar form factors f_{+} and f_{0} from our companion work [J.

Determination of |V(us)|| from a lattice QCD calculation of the K → πℓν semileptonic form factor with physical quark masses.

We calculate the kaon semileptonic form factor f+(0) from lattice QCD, working, for the first time, at the physical light-quark masses. We use gauge configurations generated by the MILC Collaboration with Nf = 2 + 1 + 1 flavors of sea quarks, which incorporate the effects of dynamical charm quarks as well as those of up, down, and strange. We employ data at three lattice spacings to extrapolate to the continuum limit.

Gynandromorphs as indicators of modularity and evolvability in ants.

Gynandromorphs, individuals that display a mosaic of male and female tissues or cell populations, have been extensively documented in solitary and social insects for over 100 years. Yet the evolutionary significance of gynandromorphs has remained obscure. Here we describe our discovery of a gynandromorph in the hyperdiverse ant genus Pheidole whose pattern of bilateral head mosaicism occurs repeatedly across a wide range of ant species.

Electron energy loss spectroscopy elucidates the elusive darkening of zinc potassium chromate in Georges Seurat's A Sunday on La Grande Jatte--1884.

The color darkening of selected brushstrokes of Georges Seurat's A Sunday on La Grande Jatte--1884 was noted as early as 1892. Artificial aging of model systems containing zinc yellow (K(2)O·4ZnCrO(4)·3H(2)O) mixed with linseed oil successfully replicated the phenomena observed on La Grande Jatte. Electron energy loss spectroscopy measurements performed on the uppermost few microns of thin sections of the paint layers (obtained with focused ion beam milling) determined that samples which turned olive green (aged at 90% RH, with SO(2) and light) contain mostly the altered species Cr(III) and that the ochre-yellow coloration of specimens aged at 50% RH with SO(2) and light is due to the presence of dichromate ions (Cr (VI)).

Identification of organic colorants in fibers, paints, and glazes by surface enhanced Raman spectroscopy.

Organic dyes extracted from plants, insects, and shellfish have been used for millennia in dyeing textiles and manufacturing colorants for painting. The economic push for dyes with high tinting strength, directly related to high extinction coefficients in the visible range, historically led to the selection of substances that could be used at low concentrations. But a desirable property for the colorist is a major problem for the analytical chemist; the identification of dyes in cultural heritage objects is extremely difficult.

Chemical fingerprinting of ready-mixed house paints of relevance to artistic production in the first half of the twentieth century. Part I: Inorganic and organic pigments.

This study reports the multi-analytical investigation of ready-mixed house paints used by artists such as Pablo Picasso (1881-1973) in the first half of the twentieth century. The pigment composition of paint swatches on four historic paint sample cards from the Art Institute of Chicago reference collection was characterized by thorough screening using Fourier transform infrared (FT-IR) and X-ray fluorescence (XRF) spectroscopies, followed by Raman spectroscopy when necessary. Spectroscopic investigations highlighted the dominance of zinc-based whites, the consistent choice of particular pigments or their mixtures, as well as the avoidance of others to achieve the various hues on the sample cards.

Noninvasive methods for the investigation of ancient Chinese jades: an integrated analytical approach.

This paper reports on an integrated analytical approach for the noninvasive characterization of Chinese nephrite samples, encompassing both geological reference specimens and museum objects. Natural variations induced by cationic substitutions, as well as human-induced alterations such as heating, which both affect color, are the focus of this contribution. Totally noninvasive methods of analysis were used, including X-ray fluorescence spectroscopy, Raman microspectroscopy, visible reflectance spectroscopy and X-ray diffraction; moreover, the feasibility of using a portable Raman spectrometer for the in-field identification of jades has been demonstrated.

Psychological symptoms of art students seeking psychotherapy.

Descriptive data concerning type and severity of psychological symptoms of 162 art students seeking psychotherapy at an art school counseling service were obtained. These undergraduate and graduate students who presented for consecutive intakes over one year completed the Symptom Checklist-90-R. Women reported more severe symptomatology than men.

Essentialism, social constructionism, and the history of homosexuality.

Social constructionism is the view that homosexuality is not an atemporal and acultural phenomenon. Rather, homosexuality exists only within certain cultures and within certain time periods, most obviously Europe and North America after the nineteenth century. Essentialism is the view that homosexuality is an essential feature of human beings and that it could be found, in principle at least, in any culture and in any time.
