description: Neodeightonia C. Booth, in Punithalingam, Mycological Papers 119: 17 (1970), MycoBank MB3450
Neodeightonia was introduced by Booth based on N. subglobosa on dead culms of Bambusa arundinacea from Sierra Leone (Punithalingam 1969). von Arx & Müller (1975) transferred N. subglobosa to Botryosphaeria and consequently reduced Neodeightonia to synonymy under Botryosphaeria. However, based on morpho-molecular data, Phillips et al. (2008) reinstated Neodeightonia as a separate lineage in Botryosphaeriaceae distinct from Botryosphaeria. Neodeightonia species are characterized by hyaline, aseptate ascospores with bipolar germ pores, surrounded by a membrane that swells in water acquiring a wing-like appearance, and hyaline, aseptate conidia that may become pigmented, 1-septate and smooth to finely roughened or striate (Liu et al. 2012, Phillips et al. 2013, 2019) (Table 4). They are typically associated with monocotyledonous plants and are mostly restricted to palms (Arecaceae) and bamboos (Poaceae) (Punithalingam 1969, Phillips et al. 2008, Liu et al. 2012, Adamčík et al. 2015, Dai et al. 2017), being primarily reported as saprobes, although a few have been reported as pathogens causing leaf spots and leaf, rachis and root rot (Ligoxigakis et al. 2013, Bengyella et al. 2015, Nishad & Ahmed 2020, Shabong & Kayang 2022, Zhang & Song 2022). Given the synonymies proposed and the species introduced herein, nine species known from culture are included in Neodeightonia based on morphological and phylogenetic analyses, namely N. chamaeropicola sp. nov., N. licuriensis (Adamčík et al. 2015), N. microspora (Dai et al. 2017), N. palmicola (Liu et al. 2010), N. phoenicum (Phillips et al. 2008), N. rattanica, N. rattanicola (Konta et al. 2016a), N. septata (Wu et al. 2022) and N. subglobosa (Phillips et al. 2008). Of these, seven have been reported from palms (N. chamaeropicola, N. licuriensis, N. palmicola, N. phoenicum, N. rattanica, N. rattanicola and N. septata), while the remaining two have been reported from bamboos (N. microspora and N. subglobosa). Recently Botryosphaeria mucosa was transferred to Neodeightonia by Zhang et al. (2021b) based on morphological analysis, but since no molecular data are available for this species its status cannot be confirmed.

description: We study the immersion of a ferromagnetic nanowire within a nematic liquid crystal using a lattice Boltzmann algorithm to solve the full three-dimensional equations of hydrodynamics. We present an algorithm for including a moving boundary, to simulate a nanowire, in a lattice Boltzmann simulation. The nematic imposes a torque on a wire that increases linearly with the angle between the wire and the equilibrium direction of the director field. By rotation of these nanowires, one can determine the elastic constants of the nematic.

description: Mesoscale molecular assemblies on the cell surface, such as cilia and filopodia, integrate information, control transport and amplify signals. Synthetic devices mimicking these structures could sensitively monitor these cellular functions and direct new ones. The challenges in creating such devices, however are that they must be integrated with cells in a precise kinetically controlled process and a device's structure and its precisely structured cell interface must then be maintained during active cellular function. Here we report the ability to integrate synthetic micro-scale filaments, DNA nanotubes, into a cell's architecture by anchoring them by their ends to specific receptors on the surfaces of mammalian cells. These filaments can act as shear stress meters: how anchored nanotubes bend at the cell surface quantitatively indicates the magnitude of shear stresses between 0-2 dyn per cm2, a regime important for cell signaling. Nanotubes can also grow while anchored to cells, thus acting as dynamic components of cells. This approach to cell surface engineering, in which synthetic biomolecular assemblies are organized within existing cellular architecture, could make it possible to build new types of sensors, machines and scaffolds that can interface with, control and measure properties of cells.

The G-dwarf problem in the Galactic spheroid

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Using two alternative [O/H]-[Fe/H] dependences, the empirical oxygen abundance distribution (EGD) is deduced from two different samples of old objects, available in the literature. Under the assumption that each distribution (with the addition of a third one previously known) is typical for the corresponding subsystem, the EGD of the Galactic spheroid is determined weighting by mass. A fit to the data is provided by simple models of chemical evolution implying both homogeneous and inhomogeneous mixing, where star formation is inhibited during halo formation and enhanced during bulge formation, with respect to the disk. The theoretical oxygen abundance distribution (TGD) is first determined for the halo and the bulge separately, and then for the Galactic spheroid weighting by mass. Simple models implying inhomogeneous mixing are able to fit an empirical age-metallicity relation (EAMR) recently determined from a homogeneous sample of globular clusters, which shows a non monotonic trend characterized by large dispersion. Some possible implications related to the formation of Galactic spheroid and disk are also discussed.

description: We present the results of rest-frame ultraviolet spectroscopic observations of a sample of 14 z~3 star-forming galaxies in the SSA22a field. These spectra are characterized by unprecedented depth in the Lyman-continuum region. For the first time, we have detected escaping ionizing radiation from individual galaxies at high redshift, with two of the 14 objects showing significant emission below the Lyman limit. We also measured the ratio of emergent flux density at 1500 AA to that in the Lyman-continuum region, for the individual detections (C49 and D3) and the sample average. If a correction for the average IGM opacity is applied to the spectra of the objects C49 and D3, we find f_1500/f_900,corr(C49)=4.5 and f_1500/f_900,corr(D3)=2.9. The average emergent flux-density ratio in our sample is =22, implying an escape fraction ~4.5 times lower than inferred from the composite spectrum in Steidel et al. (2001). If this new estimate is representative of LBGs, their contribution to the metagalactic ionizing radiation field is J_nu(900)~2.6x10^{-22} erg/s/cm^2/Hz/sr, comparable to the contribution of optically-selected quasars at the same redshift. The sum of the contributions from galaxies and quasars is consistent with recent estimates of the level of the ionizing background at z~3, inferred from the HI Ly-alpha forest optical depth. There is significant variance among the emergent far-UV spectra in our sample, yet the factors controlling the detection or non-detection of Lyman-continuum emission from galaxies are not well-determined. Because we do not yet understand the source of this variance, significantly larger samples will be required to obtain robust constraints on the galaxy contribution to the ionizing background at z~3 and beyond (abridged).

description: L'Aide Médicale à Mourir (AMM) est un sujet d'actualité au Canada. Légalisé en 2016, cette aide de fin de vie reprenant les notions d'euthanasie volontaire active et de suicide médicalement assisté, est sujette à débat depuis l'affaire Rodriguez de 1992. C'est en 2019, lors de la décision suivant l'affaire Truchon que la question de la maladie mentale entre dans les discussions parlementaires suite au retrait du critère de mort naturelle raisonnablement prévisible. Cette introduction suscite un certain problème : l'absence d'une définition consensuelle entourant la maladie mentale. Dès lors, comment légiférer l'intégration d'un terme qui n'a pas de définition claire ? Au travers des débats parlementaires concernant les projets de loi C-7, C- 39 et C-62, nous étudierons de quelle manière l'absence de contours clairs entourant la maladie mentale conduit à l'inclusion des personnes suicidaires dans cette catégorie. Cette situation soulève, au sein des débats, des questions sur la volonté des personnes atteintes de maladie mentale de recourir à l'AMM, un critère essentiel pour déterminer leur admissibilité à cette procédure.

description: Controlling the temporal mode shape of quantum light pulses has wide ranging application to quantum information science and technology. Techniques have been developed to control the bandwidth, allow shifting in the time and frequency domains, and perform mode-selective beam-splitter-like transformations. However, there is no present scheme to perform targeted multimode unitary transformations on temporal modes. Here we present a practical approach to realize general transformations for temporal modes. We show theoretically that any unitary transformation on temporal modes can be performed using a series of phase operations in the time and frequency domains. Numerical simulations show that several key transformations on temporal modes can be performed with greater than 95% fidelity using experimentally feasible specifications.

We propose constructing a scintillator-based experiment, FORward MicrOcharge SeArch (FORMOSA) in this location, and estimate the corresponding sensitivity projection. We show that FORMOSA can discover millicharged particles in a large and unexplored parameter space, and study strongly interacting dark matter that cannot be detected by ground-based direct-detection experiments. The newly proposed LHC Forward Physics Facility (FPF) provides an ideal structure to host the full FORMOSA experiment.

description: Despite great advances in the area of Semantic Web, industry rather seldom adopts Semantic Web technologies and their storage and query concepts. Instead, relational databases (RDB) are often deployed to store business-critical data, which are accessed via REST interfaces. Yet, some enterprises would greatly benefit from Semantic Web related datasets which are usually represented with the Resource Description Framework (RDF). To bridge this technology gap, we propose a fully automatic approach that generates suitable RDB models with REST APIs to access them. In our evaluation, generated databases from different RDF datasets are examined and compared. Our findings show that the databases sufficiently reflect their counterparts while the API is able to reproduce rather simple SPARQL queries. Potentials for improvements are identified, for example, the reduction of data redundancies in generated databases.

description: We extend studies of micro-solvation of carbon monoxide by a combination of high-resolution IR spectroscopy and ab initio calculations. Spectra of the (H2O)4-CO and (D2O)4-CO pentamers are observed in the C-O stretch fundamental region (~2150 cm-1). The H2O containing spectrum is broadened by predissociation, but that of D2O is sharp, enabling detailed analysis which gives a precise band origin and rotational parameters. Ab initio calculations are employed to confirm the assignment to (water)4-CO and to determine the structure, in which the geometry of the (water)4 fragment is a cyclic ring very similar to the isolated water tetramer. The CO fragment is located "above" the ring plane, with a partial hydrogen bond between the C atom and one of the "free" protons (deuterons) of the water tetramer. Together with previous results on D2O-CO, (D2O)2-CO, and (D2O)3-CO, this represents a probe of the four initial steps in the solvation of carbon monoxide at high resolution.

First language maintenance : the comparison of Chinese immigrant parents’ attitudes, the children’s language use patterns and their family environments
Creators: name: Tsai, Huei-Tzu
Publisher: name: University of British Columbia
Year: 2009

description: An exploratory study was conducted to investigate Chinese parents' attitudes toward their children's first language maintenance. Interviews were conducted to collect data from a total of 30 parents who came from two distinct socioeconomic and educational backgrounds. Fifteen parents sent their children to a university lab preschool (ULP group) and the other fifteen enrolled their children in a community-based day care (CDC group) in a Chinese-speaking neighborhood in Vancouver. The Family Environment Scale (FES) (Moos, 1974) was also used to collect information about the family social and emotional dynamics. All parents from both groups felt that it was important for their children to maintain their Chinese. However, it was found that parents and children from the CDC group used more Chinese than parents and children from the ULP group in most situations. Furthermore, the CDC parents were more concerned about the academic and literacy aspects of the language learning while the ULP parents were more personal and social oriented. These two groups of parents had similar scores in almost every sub-scale of the FES except for the sub-scales of active-recreational orientation, organization, and conflict. In the sub-scales of active-recreational orientation and organization, the ULP families had higher scores than the CDC families and there was a statistical significance between these two groups. The CDC group scored higher than the ULP group in the subscale of conflict and the scores of these two groups were statistically different. It was also found that there were positive correlations between some sub-scales scores in the FES and the language use patterns in the ULP group.

description: We present near-infrared polarimetric images of the dusty circumstellar envelope (CSE) of IRAS 19306+1407, acquired at the United Kingdom Infrared Telescope (UKIRT) using the UKIRT 1-5 um Imager Spectrometer (UIST) in conjunction with the half-waveplate module IRPOL2. We present additional 450 and 850 um photometry obtained with the Sub-mm Common User Bolometer Array (SCUBA) at the James Clerk Maxwell Telescope (JCMT), as well as archived Hubble Space Telescope (HST) F606W- and F814W-filter images. The CSE structure in polarized flux at J- and K-bands shows an elongation NNE-SSW with two bright scattering shoulders NW-SE. These features are not perpendicular to each other and could signify a recent `twist' in the outflow axis. We model the CSE using an axisymmetric light scattering (ALS) code to investigate the polarization produced by the CSE, and an axisymmetric radiation transport (DART) code to fit the SED. A good fit was achieved with the ALS and DART models using silicate grains, 0.1-0.4 um with a power-law size distribution of a^-3.5, and an axisymmetric shell geometry with an equator-to-pole contrast of 7:1. The spectral type of the central star is determined to be B1I supporting previous suggestions that the object is an early PN. We have constrained the CSE and interstellar extinction as 2.0 and 4.2 mag respectively, and have estimated a distance of 2.7 kpc. At this distance the stellar luminosity is ~4500 L_sun and the ~5300 yrs with a mass-loss rate of ~3.4x10^-5 M_sun yr^-1.

description: Wireless Sensor Networks (WSNs) are often deployed to serve mission-critical applications in inhospitable environments such as battlefield and territorial borders. Inter-node communication is essential for WSNs to effectively fulfill their tasks. In hostile setups, the WSN may be subject to damage that severs the network connectivity and disrupts the application. The network must be able to recover from the failure and restore connectivity so that the designated tasks can be carried out. Given the unattended operation of the network, the recovery should be performed autonomously. In this thesis we present AuR, an algorithm for Autonomous Repair of damaged WSN topologies. AuR operates in a distributed manner to restore connectivity in the event of multiple node failures. The design principle of AuR is based on modeling connectivity between neighboring nodes as a modified electrostatic interaction based on Coulomb's law between charges. The recovery process is initiated locally at nodes that have lost neighbors. These nodes spearhead the movement in the direction of loss so as to reconnect with other disjoint nodes. The performance of the algorithm is validated through simulation

description: Atherosclerosis is an accumulation of lipid-rich plaques within arteries and a leading cause of death worldwide. Chronic low-grade inflammation is characteristic of atherosclerosis, where monocytes and macrophages play a critical role in the progression or regression of plaque. Dipeptidyl peptidase 4 (DPP4) is increased in conditions of metabolic dysfunction, and there is a strong association between monocyte DPP4 and the development of atherosclerosis. However, a causal mechanism linking increased monocyte DPP4 activity and atherogenesis remains to be revealed. We hypothesize that DPP4 regulates proteins in circulation and in macrophages to drive inflammation and atherosclerosis progression. Using in vivo and in vitro inflammatory models, we identified that DPP4 activity is increased during inflammation, and Dpp4 mRNA is upregulated in pro-inflammatory polarized macrophages. We also found that mononuclear phagocyte DPP4 may have a role in regulating circulating immune cell populations. Ependymin-related 1 (EPDR1) was identified as a DPP4 substrate via N-terminal enrichment mass spectrometry, where transcript expression was decreased in pro-inflammatory and anti-inflammatory polarized BMDMs from males. Additionally, we found correlations between circulating DPP4 protein and Hba1c and LDLc, while both DPP4 activity and protein correlated with HDLc in patients. EPDR1 increased with age and correlated with LDLc and plasma triglycerides in apoe⁻ᐟ⁻ mice, while EPDR1 decreased with age in patients. These data suggest a role of DPP4 and EPDR1 in inflammation, macrophage phenotype, and metabolic dysfunction.

description: It has been previously shown that pannexin 1 (Panx1) channels, well known for their role in ATP release, play a key role in myogenesis. However, its role in muscle development remains to be elucidated. Using a novel skeletal-muscle-specific Panx1 knockout (Panx1^smKO) mouse model, this thesis highlights the influences Panx1 plays in muscular development and maintenance, as well as in muscle function. Loss of Panx1 led to a fiber-type switch coinciding with smaller fibers in both the tibialis anterior (TA) and soleus (SOL) muscles, reduced strength, and increased fatigue resistibility in adult male mice. Notably, these mice were observed to have fewer quiescent satellite cells (SCs) with a reduction in commitment to the myogenic lineage and a decline in fusion capabilities. Additionally, Panx1 was found to be preferentially localized among fiber-types leading to smaller type I fibers in the SOL of male mice, which is likely linked to fewer SCs in this muscle at juvenile age. On the other hand, the reduction in fiber size found in the TA due to loss of Panx1 was instead due to a switch in fiber type composition. In adult mice, both muscles Panx1^smKO had less quiescent SCs. In terms of muscle function, we found that loss of Panx1 led to reduced muscle strength, but increased resistance in male mice. Notably, all the effects resulting from loss of Panx1 in the skeletal muscle identified here in male mice were non-significant in females. Collectively, these results indicate that Panx1 plays sex-specific and muscle-specific roles in skeletal muscle development, maintenance of normal fiber type composition and quiescent SC pool, as well as in muscle function.

description: A brief narrative on how the effective radius and isophotal diameters were accepted as galaxy size measures is presented. Evidence suggests that these parameters were defined only based on observational premises, independent of any astrophysical theories. An alternative, new physically motivated size definition based on the expected gas density threshold required for star formation in galaxies is discussed. The intrinsic scatter of the size-stellar mass relation using the new size measure is 0.06 dex, three times smaller than that of the relation with the effective radius as size. The new physically motivated size measure can be adopted in upcoming deep, wide imaging surveys.

Possible Effects of Shorter-Chained Poly-and Perfluoroalkyl Substances (PFAS) Exposure on Metabolic Processes

description: The extensive use of per- and polyfluoroalkyl substances (PFAS) have sparked significant public health concerns due to their increased persistence in the environment and negative impacts on human health. Developing evidence has suggested perfluorooctanoic acid (PFOA), a well known PFAS, to contribute to the formation of metabolic syndrome. The replacement of PFOA with shorter-chained perfluoroalkyl carboxylic acids (PFCAs), such as perfluoroheptanoic acid (PFHpA) and perfluorohexanoic acid (PFHxA), has been rising. However, their impact on adipogenesis and the development of metabolic syndrome is unknown. The aim of this study was to investigate the effect of PFOA, PFHpA and PFHxA on adipogenesis in 3T3-L1 preadipocytes. All three chemicals induced adipogenesis at higher concentrations. Results demonstrated increased adipogenic marker expression and increased lipid accumulation within cells, upon PFCA treatment. We then looked at the activation of PPARγ and PPARα upon PFCA treatments. Results showed that PFOA activated both PPARγ and PPARα, while PFHpA and PFHxA only activated PPARα, suggesting that the mechanism which PFHpA and PFHxA induce adipogenesis is PPARα-mediated. Further research is required to confirm the mechanism which PFOA induces adipogenesis.

description: This qualitative study aimed to explore how people perceive and experience surveillance in the context of cancel culture. Surveillance Imaginary Theory and Moral Reasoning Theory drove the research question: how do social media users describe the construction of surveillance in the context of cancel culture? A sample of eleven individuals was recruited by convenience sampling and snowball sampling. Data were collected from semi-structured interviews. Data analysis applied an Interpretive Content Analysis approach of inductive coding to generate three main themes. Social media users described the construction of surveillance as negotiating in/visibility, including weighting the benefits and risks of different audience groups, balancing the risk of exposure against social responsibility, and constructing distinctions in visibility norms.
Shot noise of interference between independent atomic systems

description: We study shot (counting) noise of the amplitude of interference between independent atomic systems. In particular, for the two interfering systems the variance of the fringe amplitude decreases as the inverse power of the number of particles per system with the coefficient being a non-universal number. This number depends on the details of the initial state of each system so that the shot noise measurements can be used to distinguish between such states. We explicitly evaluate this coefficient for the two cases of the interference between bosons in number states and in broken symmetry states. We generalize our analysis to the interference of multiple independent atomic systems. We show that the variance of the interference contrast vanishes as the inverse power of the number of the interfering systems. This result, implying high signal to noise ratio in the interference experiments, holds both for bosons and for fermions.

description: The supersoft X-ray binary RX J0513.9-6951 shows cyclic changes between optical-low / X-ray-on states and optical-high / X-ray-off states. It is supposed to be accreting close to the Eddington-critical limit and driven by "accretion wind evolution". We seek to derive the variations in the characteristic time scales of the long-term optical light curve and to determine the implications for the physical parameters of the system. We used existing and new optical monitoring observations covering a total time span of 14 years and compared the durations of the low and high states with the model calculations of Hachisu & Kato. The cycle lengths and especially the durations of the optical high states show a longterm modulation with variations that, according to the accretion wind evolution model, would imply variations in the mass transfer rate by a factor of 5 on timescales of years.

description: Cigarette users often cite stress as a major barrier to quitting smoking. Though never examined directly, past research suggests that possessing a greater ability to exert self-control over one's behavior might weaken the negative impact that perceived stress has over smoking cessation. The present study examined the impact of perceived stress, self-control and their interaction on use of the processes of change for quitting smoking. An internet-based survey was completed by 130 adult current smokers (Mage = 29.45; SD = 10.26; 62.3% Female; 70% White) who were considering quitting in the next 6 months. Self-report measures assessed perceived stress, self-control, process use, and a number of smoking- and quitting-related variables. Analyses examined the unique, direct effects of both perceived stress and self-control on process use, and whether self-control moderated the relation between perceived stress and process use. Perceived stress was found to have a small, negative effect on use of Behavioral processes (t [127] = -1.49, f ? = 0.02) and Counterconditioning (t [127] = -2.05, f ? = 0.03). Further, self-control was found to have a small buffering effect on the negative relation between perceived stress and Counterconditioning (t [126] = 1.88, f ? = 0.03). No other direct or interaction effects were found. Further research is needed to explore the potentially buffering effect of self-control on the process of quitting smoking. If future studies support self-control as a buffer, self-control-building strategies may prove helpful in promoting quitting among cigarette users for whom stress represents a hurdle to cessation.

description: Authorship attribution is the study of determining the author of a document by analyzing its contents. Different techniques have been developed over the years in order to accomplish this goal. Computers have aided in the development of these methods over the past few decades by providing a way to quickly process large amounts of data. Until recently most studies focused on corpora composed of books, plays, and papers. I applied the methods that have proven to work well on various corpora to the Enron email corpus. I focused on using function words and n-grams to determine the authorship of emails. I then selected the method that worked the best by evaluating how well they clustered a user's emails together and by how well each method separated the emails from different users apart.

description: During the AKP (Justice and Development Party) era since 2002, Turkey visibly transformed from a secular country to a more Islamist-prone one, where the goal of raising "a pious generation" was declared as part of a top-down Islamization project. This thesis examines the mobilizing power of religion for populist appeals in politics as part of the government's religious nation-building project. The AKP's attempts at transforming the Turkish public space and politics along religious lines have been widely studied. However, the transformation of religious discourse in Turkey since the 2016 military coup attempt - thought to be led by the Gülen Movement, an influential Islamic order, and a former ally of the government - has been relatively less investigated. Based on a qualitative content analysis of the post-2016 Friday sermons issued by the Diyanet (the Directorate of Religious Affairs), the centralized government institution that runs the affairs of Sunni Islam in the country, this thesis provides an in-depth account of the AKP and President Erdoğan's expansionist politics, which underpin the use of religion in a way that aligns with their national-populist rhetoric and ideals. The findings suggest that in differentiation from the populist register that was found in Diyanet's Friday sermons, the Diyanet's rhetoric actively mobilizes "civilizationism", which frames the Turkish nation primarily as a religious community that spearheads the Muslim civilization, understood as a "geography of the heart", against its internal and external enemies. Beyond Turkey, the case of the Diyanet and its direct relation to civilizationism affirms the need to study populism as a phenomenon that embodies not only particular nationalisms, but also broader, civilizational worldviews.
Indefinite Sturm-Liouville operators $ (\sgn x) (- \frac{d^2}{dx^2} +q(x))$ with finite-zone potentials

description: The indefinite Sturm-Liouville operator $A = (\sgn x)(-d^2/dx^2+q(x))$ is studied. It is proved that similarity of $A$ to a selfadjoint operator is equivalent to integral estimates of Cauchy integrals. Also similarity conditions in terms of Weyl functions are given. For operators with a finite-zone potential, the components $\Aess$ and $\Adisc$ of $A$ corresponding to essential and discrete spectrums, respectively, are considered. A criterion of similarity of $\Aess$ to a selfadjoint operator is given in terms of Weyl functions for the Sturm-Liouville operator $-d^2/dx^2+q(x)$ with a finite-zone potential $q$. Jordan structure of the operator $\Adisc$ is described. We present an example of the operator $A = (\sgn x)(-d^2/dx^2+q(x))$ such that $A$ is nondefinitizable and $A$ is similar to a normal operator.

Motivation and Independent Persistence in Childhood Food Allergy

description: Childhood food allergy requires parents to be protective to prevent accidental exposure to potentially fatal allergens. Over time, this protective parenting style may become overgeneralized and negatively impact food allergic children's development of self-regulatory persistence. Video-recorded sessions of 66 food allergic children and 67 healthy age-matched controls (ages 3-7) working on two puzzles alongside their mothers were coded for both maternal and child behaviors. Maternal involvement, children's overall persistence, and children's independent persistence were calculated. Questionnaires of parenting style completed by mothers were also included in analyses. As expected, children's persistence on both the easy and difficult puzzles significantly increased with children's age. However, the food allergic and healthy control groups did not significantly differ in maternal involvement, overall persistence, or independent persistence. Further, exploratory moderation analyses were not supported. Future research should continue to explore parenting behaviors and children's self-regulation in childhood food allergy.

description: We explain how gapped quantum spin liquids, both conventional and 'fractonic', may be unambiguously diagnosed experimentally using the technique of multidimensional coherent spectroscopy. 'Conventional' gapped quantum spin liquids (e.g. $Z_2$ spin liquid) do not have clear signatures in linear response, but do have clear fingerprints in non-linear response, accessible through the already existing experimental technique of two dimensional coherent spectroscopy. Type I fracton phases (e.g. X-cube) are (surprisingly) even easier to distinguish, with strongly suggestive features even in linear response, and unambiguous signatures in non-linear response. Type II fracton systems, like Haah's code, are most subtle, and may require consideration of high order non-linear response for unambiguous diagnosis.

description: We discuss the seminal article in which Le Bellac and Lévy-Leblond have identified two Galilean limits of electromagnetism [1], and its modern implications. Recent works have shed a new light on the choice of gauge conditions in classical electromagnetism. We discuss various applications and experiments, such as in quantum mechanics, superconductivity, electrodynamics of continuous media, etc. Much of the current technology, where waves are not taken into account, is actually based on Galilean electromagnetism

description: A hadronic chiral SU(3) model is applied to neutron and proto-neutron stars, taking into account trapped neutrinos, finite temperature and entropy. The transition to the chirally restored phase is studied and global properties of the stars like minimum and maximum masses and radii are calculated for different cases. In addition, the effects of rotation on neutron star masses are included and the conservation of baryon number and angular momentum determine the maximum frequencies of rotation during the cooling.
Multiwavelength constraints on the unidentified Galactic TeV sources HESS J1427$-$608, HESS J1458$-$608, and new VHE $γ$-ray source candidates

description: The H.E.S.S. Galactic Plane Survey (HGPS) revealed 78 TeV sources among which 47 are not clearly associated with a known object. We present a multiwavelength approach to constrain the origin of the emission from unidentified HGPS sources. We present a generic pipeline that explores a large database of multiwavelength archival data toward any region in the Galactic plane. Along with a visual inspection of the retrieved multiwavelength observations to search for faint and uncataloged counterparts, we derive a radio spectral index that helps disentangle thermal from nonthermal emission and a mean magnetic field through X-ray and TeV data in case of a leptonic scenario. We also search for a spectral connection between the GeV and the TeV regimes with the Fermi-LAT cataloged sources that may be associated with the unidentified HGPS source. We complete the association procedure with catalogs of known objects and with the source catalogs from instruments whose data are retrieved. The method is applied on two unidentified sources, namely HESS J1427$-$608 and HESS J1458$-$608, for which the multiwavelength constraints favor the pulsar wind nebula (PWN) scenario. We model their broadband nonthermal spectra in a leptonic scenario with a magnetic field $B \lesssim 10$ $μ$G, which is consistent with that obtained from ancient PWNe. We place both sources within the context of the TeV PWN population to estimate the spin-down power and the characteristic age of the putative pulsar. We also shed light on two possibly significant $γ$-ray excesses in the HGPS: the first is located in the south of the unidentified source HESS J1632$-$478 and the second is spatially coincident with the synchrotron-emitting supernova remnant G28.6$-$0.1. The multiwavelength counterparts found toward both $γ$-ray excesses make these promising candidates for being new very-high energy $γ$-ray sources.
