description: How do party positions in a multidimensional space affect party identification? This article argues that when parties take consistent ideological positions across dimensions, they clarify their brand, fostering party identifications. An analysis that uses data from the European Social Survey and the Chapel Hill Expert Survey provides evidence for this argument. The results also indicate that the effect particularly holds for the less educated and politically less interested. In addition, ideological inconsistency affects individual parties’ electoral appeal, as parties that take different positions on two dimensions tend to have a smaller partisan base. The results provide important insights into how multidimensional party competition shapes the development of party attachments.

description: We point out that the effective channel for the interfacial thermal conductance, the inverse of Kapitza resistance, of metal-insulator/semiconductor interfaces is governed by the electron-phonon interaction mediated by the surface states allowed in a thin region near the interface. Our detailed calculations demonstrate that the interfacial thermal conductance across Pb/Pt/Al/Au-diamond interfaces are only slightly different among these metals, and reproduce well the experimental results of the interfacial thermal conductance across metal-diamond interfaces observed by Stoner et al. [Phys. Rev. Lett. 68, 1563 (1992)] and most recently by Hohensee et al. [Nature Commun. 6, 6578 (2015)].

How Can Automated Feedback Engage Middle School Students in Developing and Explaining Models?
Creators: name: Yinuo Hu

description: Developing and using models can improve middle students’ understanding of complex scientific phenomena. Providing automated feedback during modeling activities has the potential to support students in rich scientific discourse while actively engaging in modeling practices. However, existing studies on automated feedback often focus on how feedback can help students work on multiple-choice responses. To address the gap in the literature, this study used video data from a larger NSF project (#1552114) to explore how automated feedback helped 8th-grade students develop, revise, and explain scientific models of unobservable scientific phenomena.

description: We employ the nuclear lattice effective field theory (NLEFT), an efficient tool for nuclear ab initio calculations, to solve the asymmetric multihadron systems. We take the $DD^*K$ three-body system as an illustration to demonstrate the capability of the method. Here the two-body chiral interactions between $D$, $D^*$, and $K$ are regulated with a soft lattice regulator and calibrated with the binding energies of the $T_{cc}^+$, $D^{*}_{s0}(2317)$, and $D_{s1}(2460)$ molecular states. We then calculate the three-body binding energy using the NLEFT and analyze the systematic uncertainties due to the finite volume effects, the sliding cutoff, and the leading-order three-body forces. Even when the three-body interaction is repulsive (even as large as the infinite repulsive interaction), the three-body system has a bound state unambiguously with binding energy no larger than the $D_{s1}(2460)D$ threshold. To check the renormalization group invariance of our framework, we extract the first excited state. We find that when the ground state is fixed, the first excited states with various cutoffs coincide with each other when the cubic size goes larger. In addition, the standard angular momentum and parity projection technique is implemented for the quantum numbers of the ground and excited states. We find that both of them are $S$-wave states with quantum number $J^{P}=1^-$. Because the three-body state contains two charm quarks, it is easier to be detected in the Large Hadron Collider.

description: We have observed regions of three galaxy clusters at z$\sim$ [0.06, 0.09] (Abell85, Abell1205, Abell2440), as well as calibration sources with the Nancay radiotelescope (NRT) to search for 21 cm emission and fully characterize the FPGA based BAORadio digital backend. The total observation time of few hours per source have been distributed over few months, from March 2011 to January 2012, due to scheduling constraints of the NRT, which is a transit telescope. Data have been acquired in parallel with the NRT standard correlator (ACRT) back-end, as well as with the BAORadio data acquisition system. The latter enables wide band instantaneous observation of the [1250, 1500]MHz frequency range, as well as the use of powerful RFI mitigation methods thanks to its fine time sampling. A number of questions related to instrument stability, data processing and calibration are discussed. We have obtained the radiometer curves over the integration time range [0.01,10 000] seconds and we show that sensitivities of few mJy over most of the wide frequency band can be reached with the NRT. It is clearly shown that in blind line search, which is the context of HI intensity mapping for Baryon Acoustic Oscillations, the new acquisition system and processing pipeline outperforms the standard one. We report a positive detection of 21 cm emission at 3 sigma-level from galaxies in the outer region of Abell85 at 1352 MHz (14 400 km/s) corresponding to a line strength of 0.8 Jy km/s. We observe also an excess power around 1318 MHz (21 600 km/s), although at lower statistical significance, compatible with emission from Abell1205 galaxies. Detected radio line emissions have been cross matched with optical catalogs and we have derived hydrogen mass estimates.

description: Political participation opportunities have been expanding for years, most recently through digital tools. Social media platforms have become well integrated into civic and political participation. Using a cross-national sample from the United States, United Kingdom and France, this article examines whether acts of participation associated with social media should be classified using a traditional, five-factor solution to the structure of participatory acts. The distinction between online and offline participation is set aside, focusing instead on acts supported and enabled by social media, and in particular on differences between the use of Twitter and Facebook. The analysis shows that acts enabled by social media do not load with traditional factors in the structure of participation. Political acts employing Twitter and Facebook are distinct in the factor structure of participation.

description: Decay of $^{210}$Po compound nucleus formed in light and heavy-ion induced fusion reactions has been analyzed simultaneously using a consistent prescription for fission barrier and nuclear level density incorporating shell correction and its damping with excitation energy. Good description of all the excitation functions have been achieved with a fission barrier of 21.9 $\pm$ 0.2 MeV. For this barrier height, the predicted statistical pre-fission neutrons in heavy-ion fusion-fission are much smaller than the experimental values, implying the presence of dynamical neutrons due to dissipation even at these low excitation energies ($\sim$ 50~MeV) in the mass region A $\sim$ 200. When only heavy-ion induced fission excitation functions and the pre-fission neutron multiplicities are included in the fits, the deduced best fit fission barrier depends on the assumed fission delay time during which dynamical neutrons can be emitted. A fission delay of (0.8 $\pm$ 0.1 )$\times 10^{-19}$ s has been estimated corresponding to the above fission barrier height assuming that the entire excess neutrons over and above the statistical model predictions are due to the dynamics. The present observation has implication on the study of fission time scale/ nuclear viscosity using neutron emission as a probe.

Speech Perception in Spatially Separated Speech: Effect of Talker Orientation

name: Braza, Meredith
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Spatial release from masking (SRM) refers to the improved ability to recognize target speech when target and masker stimuli are spatially separated on the horizontal plane. Laboratory assessment of SRM often involves measurement of speech recognition in two spatial conditions: one in which target and interfering speech originate from directly in front of the listener, and another in which target speech originates from the front of the listener while interfering speech originates from one or both sides of the listener. 
The vast majority of research investigating SRM has been conducted with target and masker speech stimuli recorded from a microphone placed directly in front of the talker (0 azimuth). As a result, most data on SRM in listeners with normal hearing (NH) simulate a listening situation involving competing talkers that directly face the listener. 
In the real world, masking speech is produced by talkers with a range of head orientations relative to the listener. The extended high-frequency content of the masker speech at the listener’s ears will vary accordingly. The overall purpose of this study was to determine if masker talker orientation (60 degrees versus versus 0 degrees azimuth) has an effect on SRM in children and adults with NH.

description: We study quantum electrodynamics with 2+1 dimensional massless Dirac fermion around a Coulomb impurity. Around a large charge with atomic number Z > 137, the QED vacuum is expected to collapse due to the strong Coulombic force. While the relativistic quantum mechanics fails to make reliable predictions for the fate of the vacuum, the heavy ion collision experiment also does not give clear understanding of this system. Recently, the "atomic collapse" resonances were observed on graphene where an artificial nuclei can be made. In this paper, we present our nonperturbative study of the vacuum structure of the quasiparticles in graphene with a charge impurity which contains multi-body effect using bosonization method.

description: In 2011, 21% of people (age 5 or above) in the United States spoke a language other than English at home (US Census). There is a growing need for assessments that are sensitive to developmental language disorder (DLD, also commonly-known as specific language impairment, SLI) and specific enough to exclude typically-developing English language learners and bilingual children. A variety of tools have been developed for assessing DLD, many of which have been used with bilingual children. Dollaghan and Horner (2011) conducted a meta-analysis of tools that were available prior to July 2009. An updated synthesis and evaluation of current research would help clinicians make evidence-based decisions in their work with bilingual children.

Research question: What conclusions can be drawn from recent diagnostic tests of accuracy (DTAs) regarding currently-available and experimental measures for the identification of Developmental Language Disorder (DLD) in school-age bilingual children?

description: There is a pressing need to accelerate therapeutic strategies against the syndromes caused by frontotemporal lobar degeneration, including symptomatic treatments. One approach is for experimental medicine, coupling neurophysiological studies of the mechanisms of disease with pharmacological interventions aimed at restoring neurochemical deficits. Here we consider the role of glutamatergic deficits and their potential as targets for treatment. We performed a double-blind placebo-controlled crossover pharmaco-magnetoencephalography study in 20 people with symptomatic frontotemporal lobar degeneration (10 behavioural variant frontotemporal dementia, 10 progressive supranuclear palsy) and 19 healthy age- and gender-matched controls. Both magnetoencephalography sessions recorded a roving auditory oddball paradigm: on placebo or following 10 mg memantine, an uncompetitive NMDA-receptor antagonist. Ultra-high-field magnetic resonance spectroscopy confirmed lower concentrations of GABA in the right inferior frontal gyrus of people with frontotemporal lobar degeneration. While memantine showed a subtle effect on early-auditory processing in patients, there was no significant main effect of memantine on the magnitude of the mismatch negativity (MMN) response in the right frontotemporal cortex in patients or controls. However, the change in the right auditory cortex MMN response to memantine (vs. placebo) in patients correlated with individuals' prefrontal GABA concentration. There was no moderating effect of glutamate concentration or cortical atrophy. This proof-of-concept study demonstrates the potential for baseline dependency in the pharmacological restoration of neurotransmitter deficits to influence cognitive neurophysiology in neurodegenerative disease. With changes to multiple neurotransmitters in frontotemporal lobar degeneration, we suggest that individuals' balance of excitation and inhibition may determine drug efficacy, with implications for drug selection and patient stratification in future clinical trials.

Fast Radio Bursts: unveiling their local environments via high-resolution images
Creators: name: Marcote, Benito
Publisher: name: Zenodo
Year: 2022

description: Fast Radio Bursts (FRBs) are millisecond duration, extremely luminous bursts detected at radio frequencies. Hundreds of FRBs have been detected to date, since their discovery fifteen years ago, but their nature still remains unclear. To be able to clearly identify the systems associated to the production of FRBs, it is critical to determine the local environments where FRBs occur. Due to the large distances to these extragalactic sources, we need a large number of very precise localizations that can only be carried out with very long baseline interferometric (VLBI) observations. We have been conducting VLBI observations during the last years to unveil the local environments of FRBs with the European VLBI Network (EVN), currently the only instrument capable of localizing FRBs down to the milliarcsecond level. This level of precision was critical to associate the first localized FRB, 20121102A, to the inside of a low-metallicity star-forming region in a dwarf galaxy and physically related it to a compact (< 0.7 pc) persistent radio source (Chatterjee et al. 2017; Marcote et al. 2017; Tendulkar et al. 2017), and a second repeating FRB, 20180916B, to just outside the edge of a prominent star-forming region of a nearby spiral galaxy (Marcote et al. 2020). Within the PRECISE project (Pinpointing REpeating ChIme Sources with EVN dishes) we keep a monitoring of repeating FRBs on a regular basis. PRECISE aims to push these localizations to a new level: localizing tens of these FRBs with milliarcsecond accuracy, with the ultimate goal of disentangling the environments where FRBs can be produced via statistical studies of the common properties observed in different FRBs. In this talk I will make a review on FRBs and the current state of the art of this field, discuss the importance of milliarcsecond localizations, the PRECISE project, and the localizations achieved until now, which have unveiled a variety of environments where FRBs can be found that challenges multiple models, including the localization of FRB 20200120E in a completely unexpected environment: the inside of a globular cluster in M81 (Kirsten, Marcote, et al. 2022).

description: In this paper we study a spectrum $K(\mathcal{V}_k)$ such that $π_0 K(\mathcal{V}_k)$ is the Grothendieck ring of varieties and such that the higher homotopy groups contain more geometric information about the geometry of varieties. We use the topology of this spectrum to analyze the structure of $K_0[\mathcal{V}_k]$ and show that classes in the kernel of multiplication by $[\mathbb{A}^1]$ can always be represented as $[X]-[Y]$ where $X$ and $Y$ are varieties such that $[X] \neq [Y]$, $X\times \mathbb{A}^1$ and $Y\times \mathbb{A}^1$ are not piecewise isomorphic, but $[X\times \mathbb{A}^1] =[Y\times \mathbb{A}^1]$ in $K_0[\mathcal{V}_k]$. Along the way we present new proofs of the result of Larsen--Lunts on the structure on $K_0[\mathcal{V}_k]/([\mathbb{A}^1])$.

Impact of Cognitive Training on Dementia Prevention

description: With an ever-growing elderly population, the number of people with dementia is expected to triple by 2050 (Dementia, 2017). Dementia prevention is an increasingly critical issue that needs to be addressed. Mild cognitive impairment is considered an intermediate, subclinical stage between normal cognition and dementia. The most common subtype, amnestic MCI (a-MCI), is thought to be a strong predictor of future dementia (Tangalos and Petersen, 2018). It has been reported that individuals with a-MCI progress to dementia at a rate of 12-15% per year compared to 1-2% for healthy adults (Kinsella et al., 2009). A number of studies have implemented cognitive therapies for adults with MCI, but few have analyzed the long-term results of such therapies regarding cognitive decline. This prompted the authors to systematically review studies of cognitive intervention in adults with MCI and evaluate whether intervention prevents further cognitive decline into dementia.

description: The medical and scientific response to emerging and established pathogens is often severely hampered by ignorance of the genetic determinants of virulence, drug resistance and clinical outcomes that could be used to identify therapeutic drug targets and forecast patient trajectories. Taking the newly emergent multidrug-resistant bacteria Mycobacterium abscessus as an example, we show that combining high-dimensional phenotyping with whole-genome sequencing in a phenogenomic analysis can rapidly reveal actionable systems-level insights into bacterial pathobiology. Through phenotyping of 331 clinical isolates, we discovered three distinct clusters of isolates, each with different virulence traits and associated with a different clinical outcome. We combined genome-wide association studies with proteome-wide computational structural modelling to define likely causal variants, and employed direct coupling analysis to identify co-evolving, and therefore potentially epistatic, gene networks. We then used in vivo CRISPR-based silencing to validate our findings and discover clinically relevant M. abscessus virulence factors including a secretion system, thus illustrating how phenogenomics can reveal critical pathways within emerging pathogenic bacteria.

description: Filters whose porosity decreases with depth are often more efficient at removing solute from a fluid than filters with a uniform porosity. We investigate this phenomenon via an extension of homogenization theory that accounts for a macroscale variation in microstructure. In the first stage of the paper, we homogenize the problems of flow through a filter with a near-periodic microstructure and of solute transport due to advection, diffusion, and filter adsorption. In the second stage, we use the computationally efficient homogenized equations to investigate and quantify why porosity gradients can improve filter efficiency. We find that a porosity gradient has a much larger effect on the uniformity of adsorption than it does on the total adsorption. This allows us to understand how a decreasing porosity can lead to a greater filter efficiency, by lowering the risk of localized blocking while maintaining the rate of total contaminant removal.

description: Twisted magnetic fields should be ubiquitous in flare-producing active regions where the magnetic fields are strongly non-potential. It has been shown that reconnection in helical magnetic coronal loops results in plasma heating and particle acceleration distributed within a large volume, including the lower coronal and chromospheric sections of the loops. This scenario can be an alternative to the standard flare model, where particles are accelerated only in a small volume located in the upper corona. We use a combination of MHD simulations and test-particle methods, which describe the development of kink instability and magnetic reconnection in twisted coronal loops using resistive compressible MHD, and incorporate atmospheric stratification and large-scale loop curvature. The resulting distributions of hot plasma let us estimate thermal X-ray emission intensities. The electric and magnetic fields obtained are used to calculate electron trajectories using the guiding-centre approximation. These trajectories combined with the MHD plasma density distributions let us deduce synthetic HXR bremsstrahlung intensities. Our simulations emphasise that the geometry of the emission patterns produced by hot plasma in flaring twisted coronal loops can differ from the actual geometry of the underlying magnetic fields. The twist angles revealed by the emission threads (SXR) are consistently lower than the field-line twist present at the onset of the kink-instability. HXR emission due to the interaction of energetic electrons with the stratified background are concentrated at the loop foot-points in these simulations, even though the electrons are accelerated everywhere within the coronal volume of the loop. The maximum of HXR emission consistently precedes that of SXR emission, with the HXR light-curve being approximately proportional to the temporal derivative of the SXR light-curve.

description: From an outsider’s point of view at age twenty-two I appeared to be successful. Yet, I was an active alcoholic. I sought help through Alcoholics Anonymous (A.A.). I have been sober for over five and a half years. I still attend A.A. meetings on a regular basis. I have seen people transform from a selfish, hopeless state of mind, into a confident selfless, successful member of society. People go through this transformation in A.A. on a regular basis by working the twelve steps and practicing A.A.’s twelve traditions. I am incredibly grateful for the life and gifts the program of A.A. has given me. However, along with most things in life, A.A. is not a perfect program. A.A. was designed by two middle class white males in the 1930s who wrote the twelve steps and traditions. Since A.A. is a spiritually based program, it does not have anyone in charge and the twelve traditions were created as guidelines for each A.A. group to follow in order to ensure the program’s success. However, through my research this summer, I learned that the interpretations of the traditions have varied from its original text, creating a male dominate space where the abuser of sexual assault, often go unpunished because subconsciously, people do not want to criticize A.A. or kick an individual out of the meeting space.
Observation of impedance oscillations in single walled carbon nanotube bundles excited by high frequency signals

description: We report experimental observation of impedance oscillations in single-walled carbon nanotubes measured from 100 MHz to 65 GHz on coplanar wave guides and a power law dependence of the differential conductance with bias voltage. From the crossover of the real and imaginary parts of the complex impedance observed in the range of 10 GHz, we estimate a long lifetime of 15 ps that can support the claim of ballistic transport. By measuring the scattering parameters at high-frequencies of a few aligned single-walled bundles at low temperatures we show that, this observation is strongly influenced by the number of tubes available.

description: Public opinion polarisation can impair society’s ability to reach a democratic consensus in different political issue areas. This appears particularly true when the polarisation of opinions coincides with clearly identifiable social groups. The literature on public opinion polarisation has mostly focussed on the US two-party context. We lack concepts and measures that can be adapted to European countries with multi-party systems and multi-layered group identities. This article proposes a conceptualisation of polarisation between groups in society. It presents a measure that captures the overlap of ideology distributions between groups. The two-step empirical framework includes hierarchical IRT models and a measure for dissimilarity of distributions. The second part presents an empirical application of the measure based on survey data from Switzerland (1994–2016), which reveals insightful dynamics of public opinion polarisation between party supporters and education groups.
Non-circular skyrmion and its anisotropic response in thin films of chiral magnets under tilted magnetic field

description: We study the equilibrium and dynamical properties of skyrmions in thin films of chiral magnets with oblique magnetic field. The shape of an individual skyrmion is non-circular and the skyrmion density decreases with the tilt angle from the normal of films. As a result, the interaction between two skyrmions depends on the relative angle between them in addition to their separation. The triangular lattice of skyrmions under a perpendicular magnetic field is distorted into a centered rectangular lattice for a tilted magnetic field. For a low skyrmion density, skyrmions form a chain like structure. The dynamical response of the non-circular skyrmions depends on the direction of external currents.
