description: We present the first James Webb Space Telescope/NIRCam-led determination of $79.5$. Their star formation main sequence is consistent with predictions from simulations. Lastly, we introduce an analytical framework to constrain main-sequence evolution at $z>7$ based on galaxy ages and basic assumptions, through which we find results consistent with expectations from cosmological simulations. While this work only gives a glimpse of the properties of typical galaxies that are thought to drive the reionization of the universe, it clearly shows the potential of JWST to unveil unprecedented details on galaxy formation in the first billion years.

Learning, motivation and emotion

description: Deficits in AS have a direct impact on executive functions and, particularly relevant, affect goal-directed behavior (Campabadal Delgado et al., 2016, p.7). Neuroimaging techniques reveal a highly distributed function, overlapping across different brain networks, both anatomically and functionally, but mainly located within the thalamo-frontoparietal lateralized network in the right hemisphere (RH). Moreover, it is also associated with emotionally laden learning (Bourne and Watling, 2015, p. 41; Cantú, Lera, and Baca, 2017, p.21). At present, there is no doubt that a relationship exists between emotion, motivation (EMM), and cognitive processes, especially attentional processes. This relationship and its effects on cognition in general have been well-studied, although based on the consulted literature, we believe that there are gaps in experimental research regarding the involvement of EMM processes and aspects such as learned helplessness (IA), attentional biases (SA), lack of activation (CA), and their relation to pathologies and learning difficulties, both in adults and adolescents.
CBCT Image Quality Assessment Testing Clinically Relevant Volume Orientation and Position
Creators: name: Kurzweg, Brittany
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Introduction and Objectives: Some physical measures of CBCT image quality correlate well with diagnostic image quality. Traditionally, these measures have been assessed in the center in a standard orientation. The purpose of this study was to test whether measures of image quality vary as a function of test tool location, orientation and dose. The second purpose was to determine if there was an association between objective and subjective image quality. Methods: CBCT objective image quality was assessed with one standard and three modified phantoms using five fields of view. The test tool was located at the center of the phantom (standard), at the periphery (Mod1), angled and at the center (Mod2), or angled plane and at the periphery (Mod3). Phantoms were imaged with a Carestream CS 9300 CBCT scanner (Carestream, Rochester, NY), using SDSR (180-250µm voxel/90kVp/64mAs) and LDLR (400µm voxel/85kVp/14.5mAs) for each field-of-view. Contrast-to-noise ratio (CNR) and 10% modulation transfer function (MTF) were assessed in three repeated volumes. Data were analyzed using ANOVA and Tukey’s HSD. Subjective image quality was assessed with a pairwise comparison of anatomical landmarks corresponding to the test tool locations and orientations. Data were analyzed using logistic regression. Results: CNR differed by phantom (p<0.0001) and dose (p<0.0001) for the 8x8 and 17x11 cm FOVs. Mod3 displayed significantly greater CNR than other phantoms. Low dose protocol provided higher CNR. MTF differed only by dose (p<0.0001) for the 8x8, 17x6, and 17x11 cm FOVs. SDSR provided higher MTF. Dose protocol was statistically significant for subjective image quality. Observers preferred images with higher MTF rather than higher CNR. Mod3 was negatively associated with observer preference. The 17x6cm FOV was positively associated with observer preference. Conclusions: CNR improved for a peripherally positioned angled test tool (Mod3). Reduced kVp and larger voxels appear to counteract the effect of reduced mAs producing improved CNR at LDLR. Thus, image quality parameters are different at the center of a CBCT volume when compared to the periphery, depend on the orientation of the object, and vary as a function of kVp and voxel size. Observers preferred images with a higher MTF rather than higher CNR.

description: We exploit James Webb Space Telescope (JWST) NIRCam observations from the GLASS-JWST-Early Release Science program to investigate galaxy stellar masses at z>7. We first show that JWST observations reduce the uncertainties on the stellar mass by a factor of at least 5-10, when compared with the highest quality data sets available to date. We then study the UV mass-to-light ratio, finding that galaxies exhibit a two orders of magnitude range of M/L_UV values for a given luminosity, indicative of a broad variety of physical conditions and star formation histories. As a consequence, previous estimates of the cosmic star stellar mass density - based on an average correlation between UV luminosity and stellar mass - can be biased by as much as a factor of ~6. Our first exploration demonstrates that JWST represents a new era in our understanding of stellar masses at z>7, and therefore of the growth of galaxies prior to cosmic reionization.

Assessing the Causes and Effects of Electoral Volatility: Party System Fragmentation, Time, and Executive Turnover
Creators: name: Shair-Rosenfield, Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: What effect do political parties and the system in which they function have on the amount of electoral instability generated during election periods? This study confirms that party system fragmentation, disaggregated into twin components of party system size and discontinuity, plays a deterministic role on volatility levels and that conceptual disaggregation improves the fit of this model over alternate models. Additionally, the inclusion of a time-sensitive control variable reveals the significant impact of interelection period length which had not been controlled for in earlier analyses. The results of this analysis do not uphold prior findings of region- or time-specific data with respect to alternative explanations of economic voting, institutional characteristics, or class cleavage structures. Finally, examination of the relationship between electoral volatility and executive turnover reveals that party system size and discontinuity, as well as time, can mitigate the negative effect of electoral volatility on executive policy tenure.

description: We study the quasiadiabatic dynamics of a one-dimensional system of ultracold bosonic atoms loaded in an optical superlattice. Focusing on a slow linear variation in time of the superlattice potential, the system is driven from a conventional Mott insulator phase to a superlattice-induced Mott insulator, crossing in between a gapless critical superfluid region. Due to the presence of a gapless region, a number of defects depending on the velocity of the quench appear. Our findings suggest a power-law dependence similar to the Kibble-Zurek mechanism for intermediate values of the quench rate. For the temporal ranges of the quench dynamics that we considered, the scaling of defects depends nontrivially on the width of the superfluid region.

The Impact of the NCAA Emerging Sports Program for Women on Title IX Compliance: A 10-Year Longitudinal Study
Creators: name: McCollum, Emilee
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: In 1993, the Emerging Sports Program for Women was created in an effort to combat the discrepancy seen in athletic participation rates of men compared to women in the NCAA. The Emerging Sports Program allows schools to provide additional athletics opportunities to women by lessening the requirements of becoming a full-status NCAA championship sport compared to a non-emerging sport. Until this point in time, no research has been conducted on the overall effectiveness of the Emerging Sports Program. This study provides a ten-year analysis of how the Emerging Sport Program impacted Title IX compliance of participation opportunities for women. Specifically, the substantial proportionality of schools that added an emerging sport between the academic years of 2004-2005 and 2013-2014 was calculated to determine any change in compliance from the addition of an emerging sport. The results show that the Emerging Sports Program has made a positive impact on Title IX compliance.

description: The 3D Bondi-Metzner-Sachs (BMS$_3$) algebra that is the asymptotic symmetry algebra at null infinity of the $1+2$D asymptotically flat space-time is isomorphic to the $1+1$D Carrollian conformal algebra. Building on this connection, various preexisting results in the BMS$_3$-invariant field theories are reconsidered in light of a purely Carrollian perspective in this paper. In direct analogy to the covariant transformation laws of the Lorentzian tensors, the flat Carrollian multiplets are defined and their conformal transformation properties are established. A first-principle derivation of the Ward identities in a $1+1$D Carrollian conformal field theory (CCFT) is presented. This derivation introduces the use of the complex contour-integrals (over the space-variable) that provide a strong analytic handle to CCFT. The temporal step-function factors appearing in these Ward identities enable the translation of the operator product expansions (OPEs) into the language of the operator commutation relations and vice versa, via a contour-integral prescription. Motivated by the properties of these step-functions, the $iε$-forms of the Ward identities and OPEs are proposed that permit for the hassle-free use of the algebraic properties of the latter. Finally, utilizing the computational techniques developed, it is shown that the modes of the quantum energy-momentum tensor operator generate the centrally extended version of the infinite-dimensional $1+1$D Carrollian conformal algebra.

description: Out-of-equilibrium systems continuously generate entropy, with its rate of production being a fingerprint of non-equilibrium conditions. In small-scale dissipative systems subject to thermal noise, fluctuations of entropy production are significant. Hitherto, mean and variance have been abundantly studied, even if higher moments might be important to fully characterize the system of interest. Here, we introduce a graphical method to compute any moment of entropy production for a generic discrete-state system. Then, we focus on a paradigmatic model of active particles, i.e., run-and-tumble dynamics, which resembles the motion observed in several microorganisms. Employing our framework, we compute the first three cumulants of the entropy production for a discrete version of this model. We also compare our analytical results with numerical simulations. We find that as the number of states increases, the distribution of entropy production deviates from a Gaussian. Finally, we extend our framework to a continuous state-space run-and-tumble model, using an appropriate scaling of the transition rates. The approach here presented might help uncover the features of non-equilibrium fluctuations of any current in biological systems operating out-of-equilibrium.

description: Motivated by the recent discovery of a charmonium $X(3960)$ in $B$ decays by the LHCb Collaboration, the likely existence of two bound/virtual states (denoted by $ X_{s\bar{s}}$ and $ X_{q\bar{q}}$) below the $D_{s}^{+}D_{s}^{-}$ and $\bar{D}D$ mass thresholds has been re-examined recently. In this work, we employ the effective Lagrangian approach to calculate their production rates in $B$ decays utilizing triangle diagrams. Our results show that the production yields of $B^{+}\to X_{s\bar{s}} K^{+}$ and $B^{+}\to X_{q\bar{q}} K^{+}$ are of the order of $10^{-4}$, in agreement with the relevant experimental data, which indicates that, if the $D_{s}^{+}D_{s}^{-}$ and $\bar{D}D$ bound states indeed exist, they can be detected in $B$ decays. Moreover, we calculate the production rate of $B^{+}\to X(3960) K^{+}$ assuming that $X(3960)$ is a resonant state of $D_{s}^{+}D_{s}^{-}$ and find that it is also of the order of $10^{-4}$ but a bit smaller than that as a $D_s^+D_s^-$ bound state.

description: Star-forming galaxies can exhibit strong morphological differences between the rest-frame far-UV and optical, reflecting inhomogeneities in star-formation and dust attenuation. We exploit deep, high resolution NIRCAM 7-band observations to take a first look at the morphology of galaxies in the epoch of reionization ($z>7$), and its variation in the rest-frame wavelength range between Lyman $α$ and 6000-4000Å, at $z=7-12$. We find no dramatic variations in morphology with wavelength -- of the kind that would have overturned anything we have learned from the Hubble Space Telescope. No significant trends between morphology and wavelengths are detected using standard quantitative morphology statistics. We detect signatures of mergers/interactions in 4/19 galaxies. Our results are consistent with a scenario in which Lyman Break galaxies -- observed when the universe is only 400-800 Myrs old - are growing via a combination of rapid galaxy-scale star formation supplemented by accretion of star forming clumps and interactions.

description: How passive galaxies form, and the physical mechanisms which prevent star formation over long timescales, are some of the most outstanding questions in understanding galaxy evolution. The properties of quiescent galaxies over cosmic time provide crucial information to identify the quenching mechanisms. Passive galaxies have been confirmed and studied out to $z\sim4$, but all of these studies have been limited to massive systems (mostly with $\log{(M_{\rm star}/M_{\odot})}>10.8$). Using James Webb Space Telescope (JWST) NIRISS grism slitless spectroscopic data from the GLASS JWST ERS program, we present spectroscopic confirmation of two quiescent galaxies at $z_{\rm spec}=2.650^{+0.004}_{-0.006}$ and $z_{\rm spec}=2.433^{+0.032}_{-0.016}$ (3$σ$ errors) with stellar masses of $\log{(M_{\rm star}/M_{\odot})}=10.53^{+0.18}_{-0.06}$ and $\log{(M_{\rm star}/M_{\odot})}=9.93^{+0.06}_{-0.07}$ (corrected for magnification factors of $μ=2.0$ and $μ=2.1$, respectively). The latter represents the first spectroscopic confirmation of the existence of low-mass quiescent galaxies at cosmic noon, showcasing the power of JWST to identify and characterize this enigmatic population.

We also examine the criteria of instability for commonly studied exotic compact objects with membranes, such as gravastars, AdS bubbles and thin-shell wormholes. For example, a gravastar which satisfies the weak energy condition turns out to be dynamically unstable. A thin-layer black hole mimicker is stable only if it has positive pressure and negative surface density (such as a wormhole), or vice versa.

description: In this paper, an on-chip photonic sampled and quantized analog-to-digital converter (ADC) on thin-film lithium niobate platform is experimentally demonstrated. Using two phase modulators as a sampler and a 5$\times$5 multimode interference (MMI) coupler as a quantizer, an 1 GHz sinusoidal analog input signal was successfully converted to a digitized output with a 20 GSample/s sampling rate. To evaluate the system performance, the quantization curves together with the transfer function of the ADC were measured. The experimental effective number of bits (ENOB) was 3.17 bit. The demonstrated device is capable of operating at a high frequency up to 70 GHz, making it a promising solution for on-chip ultra-high speed analog-to-digital conversion.
Measuring Religious Identity: How Religious Centrality and Identity Salience Relate to Adolescent Behavior
Creators: name: Morris, Sarah Margaret
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Sociologists of religion and adolescence often employ questions about how important religion is to an individual (religious centrality) in order to indirectly measure the likelihood that an individual will act on a religious identity (religious identity salience). While measures of religious centrality are seemingly indirect measures of religious identity salience, identity theorists have shown that as components of identity, centrality and salience are conceptually and empirically distinct. Utilizing the National Study of Youth and Religion, I take this research in identity theory and place it in a religious context to explore how these two components of religious identity are empirically and substantively related, and how their relationship affects our assessment of the association between religious identity and behavior. Findings include: 1) measures of religious centrality are not sufficient as indirect measures of religious identity salience; 2) religious identity salience only partially mediates the relationship between religious centrality and behavior, contrary to popular assumption; and 3) these two components of religious identity interact such that adolescents who have both high levels of religious centrality and high levels of religious identity salience have significantly different likelihoods of participating in certain behaviors than adolescents who have high levels of only one or the other. Implications for future research on religious identity and behavior are discussed.
Quantifying the lucky droplet model for rainfall

description: It is difficult to explain rainfall from ice-free clouds, because the timescale for the onset of rain showers is shorter than the mean time for collisions between microscopic water droplets. It has been suggested that raindrops are produced from very rare ' lucky' droplets, which undergo a large number of collisions on a timescale which is short compared to the mean time for a the first collision. This work uses large deviation theory to develop estimates for the timescale for the onset of a rain shower, as a function of the collision rate coefficients. The growth history of the fast-growing droplets which do become raindrops is discussed. It is shown that their first few collisions are always approximately equally spaced in time, regardless of how the mean time for typical droplets varies as a function of the number of collisions.

Distance Education Perspectives and Practices of Educators in an Allied Medical Program: A Grounded Theory Approach within the Phenomenological Tradition
Creators: name: Carungcong, Maria Freya T.
Publisher: name: Zenodo
Year: 2022

description: Framing the study within the Phenomenological Tradition, it asked the questions why do educators engage in distance education. To discover the meaning and purpose of distance education to educators in the allied medical field the study looked into the perspectives of the educators and their practices in Distance Education. The phenomenological tradition with the methodology of the grounded theory approach was applied in this study to gather data, analyze and understand the accounts of six teachers in an allied medical program at a private university. The phenomenological tradition in research can obtain authentic data by providing open ended questions and flexibility that may allow the participants to narrate salient events and experiences significant to distance education. By applying the strength of the traditional qualitative research approach to a methodical approach in data analysis, theory is built thru the analysis of relationships thru the components revealed within a phenomenon (Brower 1995, in Jeong, 2009). The outcome of the study presented the phenomenological model of distance education in an allied medical field that provides the perspectives, practices in teaching and transitioning to distance education. The study generated the TIE Theory on distance education that explains the essence of distance education. The TIE theory states the following on distance education: a)Transitioning to DE involves planning and provision of accessible learning resources to provide a formal mode of distance education that can promote the quality of life of the educators and the learners, (b) Instructional designing and technology are intertwined in the teaching practices of DE to address transactional distance and secure the integrity and quality of education, and (c) Education that is equivalent to face-to-face mode of education that uses varying modes of communication to address the needs of the learners, achieve learning and program outcomes and expand educational services. The TIE Theory can be the framework of distance education in allied medical education. With this theory, institutions would be able to provide an explanation for practicing DE in allied medical education and be guided when conducting needs assessment and program evaluations to maintain the quality of education

description: Galactic dust emission is often accounted for in cosmic microwave background (CMB) analyses by fitting a simple two-parameter modified blackbody (MBB) model in each pixel, which nominally accounts for the temperature and opacity of the dust. While this may be a good approximation for individual dust clouds, typically a number of such clouds are found along each line of sight and within each angular pixel, resulting in a superposition of their spectra. In this paper, we study the effects of this superposition on pixel-based foreground fitting strategies by modelling the spectral energy distribution (SED) in each pixel as the integral of individual MBB spectra over various physically-motivated statistical distributions of dust cloud properties. We show that fitting these SEDs with the simple two-parameter MBB model generally results in unbiased estimates of the CMB Stokes Q and U amplitudes in each pixel, unless there are significant changes in both the dust SED and polarization angle along the line of sight, in which case significant ($ > 10σ$) biases are observed in an illustrative model. We also find that the best-fit values of the dust temperature, $T_d$, and spectral index, $β_d$, are significantly biased away from the mean/median of the corresponding statistical distributions when the distributions are broad, suggesting that MBB model fits can give an unrepresentative picture of the physical properties of the dust at microwave wavelengths if not interpreted carefully. Using a Fisher matrix analysis, we also determine the experimental sensitivity required to recover the parameters of the $T_d$ and $β_d$ distributions themselves by fitting a probabilistic MBB model, finding that only the parameters of broad distributions can be measured by SED fitting on a single line of sight.

description: Assuming confirmation of the anomalies in semi-leptonic $B$-decays, their explanation in terms of the exchange of a massive vector leptoquark field, $U_μ^a$, of charge 2/3, appears to require the inclusion of $U_μ^a$ in the vector multiplet of the adjoint of Pati-Salam $SU(4)$, $\mathcal{G}_μ^A$, as well as the introduction of vector-like fermions, $F_j$, in the fundamental of $SU(4)$. We consider simplified models characterised by the nature of the $SU(4)$ symmetry (global or local), by the number of vector-like fermions, and by the couplings of the Higgs boson to SM fermions (direct or induced by mixing with the vector-like fermions). In all cases, we implement a minimal breaking of a $U(2)^n_f$ flavour symmetry, with a single motivated exception. We then perform a global fit including the main observables sensitive to exchanges of the $\mathcal{G}_μ^A$ at tree level and in loops dominated by logs insensitive to the UV completion.

description: The covariance matrices of power-spectrum (P(k)) measurements from galaxy surveys are difficult to compute theoretically. The current best practice is to estimate covariance matrices by computing a sample covariance of a large number of mock catalogues. The next generation of galaxy surveys will require thousands of large volume mocks to determine the covariance matrices to desired accuracy. The errors in the inverse covariance matrix are larger and scale with the number of P(k) bins, making the problem even more acute. We develop a method of estimating covariance matrices using a theoretically justified, few-parameter model, calibrated with mock catalogues. Using a set of 600 BOSS DR11 mock catalogues, we show that a seven parameter model is sufficient to fit the covariance matrix of BOSS DR11 P(k) measurements. The covariance computed with this method is better than the sample covariance at any number of mocks and only ~100 mocks are required for it to fully converge and the inverse covariance matrix converges at the same rate. This method should work equally well for the next generation of galaxy surveys, although a demand for higher accuracy may require adding extra parameters to the fitting function.

description: We present the serendipitous discovery of a late T-type brown dwarf candidate in JWST NIRCam observations of the Early Release Science Abell 2744 parallel field. The discovery was enabled by the sensitivity of JWST at 4~$μ$m wavelengths and the panchromatic 0.9--4.5~$μ$m coverage of the spectral energy distribution. The unresolved point source has magnitudes F115W = 27.95$\pm$0.15 and F444W = 25.84$\pm$0.01 (AB), and its F115W$-$F444W and F356W$-$F444W colors match those expected for other, known T dwarfs. We can exclude it as a reddened background star, high redshift quasar, or very high redshift galaxy. Comparison with stellar atmospheric models indicates a temperature of $T_{eff}$ $\approx$ 600~K and surface gravity $\log{g}$ $\approx$ 5, implying a mass of 0.03~M$_{\odot}$ and age of 5~Gyr. We estimate the distance of this candidate to be 570--720~pc in a direction perpendicular to the Galactic plane, making it a likely thick disk or halo brown dwarf. These observations underscore the power of JWST to probe the very low-mass end of the substellar mass function in the Galactic thick disk and halo.

description: Heritage speakers of Korean were recorded producing Korean and English stops and compared to the results of those produced by their non-heritage speaker peers in order to better understand the roles of first language attrition and language transfer, as well as the validity of the permanence hypothesis proposed in the Native Language Neural Commitment theory. The permanence hypothesis weighs age of first language acquisition as highly important in that after acquiring their sound categories, native speakers will persist in using those parameters throughout their lives. This study found that while the permanence hypothesis does have some credence in the participants’ Korean aspirated stops, which were produced like their childhood input (i.e. their parents’), it also encountered signs of first language attrition in the form of their ∆VOT, which was not produced like their parents’, and language transfer from Korean to English in the voiceless aspirated stop category, which was produced like a Korean stop in both languages. These results demonstrate the complexity of language acquisition, retention, and language transfer in bilinguals, and in heritage speakers in particular.

description: We prove an integral representation result for functionals with growth conditions which give coercivity on the space $SBD^p(Ω)$, for $Ω\subset\mathbb{R}^2$. The space $SBD^p$ of functions whose distributional strain is the sum of an $L^p$ part and a bounded measure supported on a set of finite $\mathcal{H}^{1}$-dimensional measure appears naturally in the study of fracture and damage models. Our result is based on the construction of a local approximation by $W^{1,p}$ functions. We also obtain a generalization of Korn's inequality in the $SBD^p$ setting.

description: The Butterfly’s Way, publié en 2001, relate, à travers 33 histoires brèves, l’expérience de la diaspora haïtienne, particulièrement en Amérique du Nord, qui, prise entre deux cultures, cherche à affirmer son identité. Cette thèse est une réflexion sur le processus de traduction française/créole d’une sélection de textes tirés de ce recueil. Notre intérêt dans cette traduction est de souligner le caractère haïtien des personnages à travers leur discours. La question posée était de savoir s’il était risqué ou non d’introduire le créole dans la traduction de TBW. Nous avons tenté d’y répondre à travers un parallèle entre les deux langues en présence en sol haïtien et leur comportement vis-à-vis l’une de l’autre, et des pistes de réflexion proposées par des chercheurs en traductologie et en linguistique.

Parkinson's Disease

description: Parkinson’s disease is a highly prevalent multifactorial neurodegenerative disorder caused by a complex cascade of interactions between various genetic and environmental factors. Due to this, the majority of cases are termed idiopathic. However, about 10% of PD cases are due to defined genetic factors. Interestingly, both idiopathic and familial cases of PD share mitochondrial dysfunction as a central component in the pathology of the disease. The mitochondrial protease, presenilin-associated rhomboid-like (PARL), is one such Parkinson's disease-linked gene, and is associated with diverse processes including mitochondrial dynamics, active inhibition of unnecessary apoptosis and mitophagy in Drosophila and yeast. Here, I investigated the role of the two zebrafish parl paralogs, parla and parlb, through stable CRISPR-Cas9 mediated mutagenesis. I injected wild type embryos with sgRNAs targeting parla and parlb loci, successfully producing indel mutations in parlb and multi-exon deletions in parla at mutation efficiencies of 74% and 40%, respectively. Through whole mount in situ hybridization experiments against th1, I saw no change in dopaminergic (DA) neuron development displayed by parlb mutants compared to wild types. Injection of parla splice blocking morpholinos into parlb mutants indicates that proper DA neuron development may depend principally on Parla function and loss of both Parla and Parlb function increases larval mortality. These results suggest a negative epistatic relationship between the parl paralogs as seen by the more severe phenotype observed in the loss of both Parla and Parlb function compared to the individual effects.

description: Kepler-289 is a three-planet system containing two sub-Neptunes and one cool giant planet orbiting a young, Sun-like star. All three planets exhibit transit timing variations (TTVs), with both adjacent planet pairs having orbital periods close to the 2:1 orbital resonance. We observe two transits of Kepler-289c with the Wide-field InfraRed Camera (WIRC) on the 200" Hale Telescope at Palomar Observatory, using diffuser-assisted photometry to achieve space-like photometric precision from the ground. These new transit observations extend the original four-year Kepler TTV baseline by an additional 7.5 years. We re-reduce the archival Kepler data with an improved stellar activity correction and carry out a joint fit with the Palomar data to constrain the transit shapes and derive updated transit times. We then model the TTVs to determine the masses of the three planets and constrain their densities and bulk compositions. Our new analysis improves on previous mass and density constraints by a factor of two or more for all three planets, with the innermost planet showing the largest improvement. Our updated atmospheric mass fractions for the inner two planets indicate that they likely have hydrogen-rich envelopes, consistent with their location on the upper side of the radius valley. We also constrain the heavy element composition of the outer saturn-mass planet, Kepler-289c, for the first time, finding that it contains 30.5 $\pm$ 6.9 $M_{\oplus}$ of metals. We use dust evolution models to show that Kepler-289c must have formed beyond 1~au, and likely beyond 3~au, and then migrated inward.

Blind testing of cross-linking/mass spectrometry hybrid methods in CASP11

description: Hybrid approaches combine computational methods with experimental data. The information contained in the experimental data can be leveraged to probe the structure of proteins otherwise elusive to computational methods. Compared with computational methods, the structures produced by hybrid methods exhibit some degree of experimental validation. In spite of these advantages, most hybrid methods have not yet been validated in blind tests, hampering their development. Here, we describe the first blind test of a specific cross-link based hybrid method in CASP. This blind test was coordinated by the CASP organizers and utilized a novel, high-density cross-linking/mass-spectrometry (CLMS) approach that is able to collect high-density CLMS data in a matter of days. This experimental protocol was developed in the Rappsilber laboratory. This approach exploits the chemistry of a highly reactive, photoactivatable cross-linker to produce an order of magnitude more cross-links than homobifunctional cross-linkers. The Rappsilber laboratory generated experimental CLMS data based on this protocol, submitted the data to the CASP organizers which then released this data to the CASP11 prediction groups in a separate, CLMS assisted modeling experiment. We did not observe a clear improvement of assisted models, presumably because the properties of the CLMS data-uncertainty in cross-link identification and residue-residue assignment, and uneven distribution over the protein-were largely unknown to the prediction groups and their approaches were not yet tailored to this kind of data. We also suggest modifications to the CLMS-CASP experiment and discuss the importance of rigorous blind testing in the development of hybrid methods.

Enlarging the notion of additivity of resource quantifiers

description: Whenever a physical quantity becomes essential to the realization of useful tasks, it is desirable to define proper measures or monotones to quantify it. In quantum mechanics, coherence, entanglement, and Bell nonlocality are examples of such quantities. Given a quantum state $\varrho$ and a quantifier ${\cal E}(\varrho)$, both arbitrary, it is a hard task to determine ${\cal E}(\varrho^{\otimes N})$. However, if the figure of merit $\cal{E}$ turns out to be additive, we simply have ${\cal E}(\varrho^{\otimes N})=N e$, with $e={\cal E}(\varrho)$. In this work we generalize this useful notion through the inner product ${\cal E}(\varrho^{\otimes N}) = \vec{N}\cdot \vec{e}$, where $\vec{e}=({\cal E}(\varrho^{\otimes i_1}), {\cal E}(\varrho^{\otimes i_2}),\dots,{\cal E}(\varrho^{\otimes i_q}) )$ is a vector whose $q$ entries are the figure of merit under study calculated for some numbers of copies smaller than $N$ ($1 \le i_1

Constraints on $s-\bar s$ asymmetry of the proton in chiral effective theory

description: We compute the $s-\bar s$ asymmetry in the proton in chiral effective theory, using phenomenological constraints based upon existing data. Unlike previous meson cloud model calculations, which accounted for kaon loop contributions with on-shell intermediate states alone, this work includes off-shell terms and contact interactions, which impact the shape of the $s-\bar s$ difference. We identify a valence-like component of $s(x)$ which is balanced by a $δ$-function contribution to $\bar s(x)$ at $x=0$, so that the integrals of $s$ and $\bar s$ over the experimentally accessible region $x > 0$ are not equal. Using a regularization procedure that preserves chiral symmetry and Lorentz invariance, we find that existing data limit the integrated value of the second moment of the asymmetry to the range $-0.07 \times 10^{-3} \leq \langle x(s-\bar s) \rangle \leq 1.12 \times 10^{-3}$ at a scale of $Q^2=1 $GeV$^2$. This is too small to account for the NuTeV anomaly and of the wrong sign to enhance it.
