description: We review theoretical models of Population III.1 star formation, focusing on the protostellar feedback processes that are expected to terminate accretion and thus set the mass of these stars. We discuss how dark matter annihilation may modify this standard feedback scenario. Then, under the assumption that dark matter annihilation is unimportant, we predict the mass of stars forming in 12 cosmological minihalos produced in independent numerical simulations. This allows us to make a simple estimate of the Pop III.1 initial mass function and how it may evolve with redshift.

description: Site-specific estimation of lime requirement requires high-resolution maps of soil organic carbon (SOC), clay and pH. These maps can be generated with digital soil mapping models fitted on covariates observed by proximal soil sensors. However, the quality of the derived maps depends on the applied methodology. We assessed the effects of (i) training sample size (5–100); (ii) sampling design (simple random sampling (SRS), conditioned Latin hypercube sampling (cLHS) and k-means sampling (KM)); and (iii) prediction model (multiple linear regression (MLR) and random forest (RF)) on the prediction performance for the above mentioned three soil properties. The case study is based on conditional geostatistical simulations using 250 soil samples from a 51 ha field in Eastern Germany. Lin’s concordance correlation coefficient (CCC) and root-mean-square error (RMSE) were used to evaluate model performances. Results show that with increasing training sample sizes, relative improvements of RMSE and CCC decreased exponentially. We found the lowest median RMSE values with 100 training observations i.e., 1.73%, 0.21% and 0.3 for clay, SOC and pH, respectively. However, already with a sample size of 10, models of moderate quality (CCC > 0.65) were obtained for all three soil properties. cLHS and KM performed significantly better than SRS. MLR showed lower median RMSE values than RF for SOC and pH for smaller sample sizes, but RF outperformed MLR if at least 25–30 or 75–100 soil samples were used for SOC or pH, respectively. For clay, the median RMSE was lower with RF, regardless of sample size.

Piers Plowman and the Poetics of Enigma: Riddles, Rhetoric, and Theology
Creators: name: Gruenler, Curtis A.
Publisher: name: University of Notre Dame
Year: 2023

description: In this book, Curtis Gruenler proposes that the concept of the enigmatic, latent in a wide range of medieval thinking about literature, can help us better understand in medieval terms much of the era's most enduring literature, from the riddles of the Anglo-Saxon bishop Aldhelm to the great vernacular works of Dante, Chaucer, Julian of Norwich, and, above all, Langland's _Piers Plowman_. Riddles, rhetoric, and theology-the three fields of meaning of _aenigma_ in medieval Latin-map a way of thinking about reading and writing obscure literature that was widely shared across the Middle Ages. The poetics of enigma links inquiry about language by theologians with theologically ambitious literature. Each sense of enigma brings out an aspect of this poetics. The playfulness of riddling, both oral and literate, was joined to a Christian vision of literature by Aldhelm and the Old English riddles of the Exeter Book. Defined in rhetoric as an obscure allegory, enigma was condemned by classical authorities but resurrected under the influence of Augustine as an aid to contemplation. Its theological significance follows from a favorite biblical verse among medieval theologians, 'We see now through a mirror in an enigma, then face to face' (1 Cor. 13:12). Along with other examples of the poetics of enigma, _Piers Plowman_ can be seen as a culmination of centuries of reflection on the importance of obscure language for knowing and participating in endless mysteries of divinity and humanity and a bridge to the importance of the enigmatic in modern literature. This book will be especially useful for scholars and undergraduate students interested in medieval European literature, literary theory, and contemplative theology.
Bures geodesics and quantum metrology

Year: 2023
Subjects: subject: Quantum Physics (quant-ph)

description: We study the geodesics on the manifold of mixed quantum states for the Bures metric. It is shown that these geodesics correspond to physical non-Markovian evolutions of the system coupled to an ancilla. Furthermore, we argue that geodesics lead to optimal precision in single-parameter estimation in quantum metrology. More precisely, if the unknown parameter $x$ is a phase shift proportional to the time parametrizing the geodesic, the estimation error obtained by processing the data of measurements on the system is equal to the smallest error that can be achieved from joint detections on the system and ancilla, meaning that there is no information loss on this parameter in the ancilla. This error can saturate the Heisenberg bound. Reciprocally, assuming that the system-ancilla output and input states are related by a unitary $e^{-i x H}$ with $H$ a $x$-independent Hamiltonian, we show that if the error obtained from measurements on the system is equal to the minimal error obtained from joint measurements on the system and ancilla then the system evolution is given by a geodesic. In such a case, the measurement on the system bringing most information on $x$ is $x$-independent and can be determined in terms of the intersections of the geodesic with the boundary of quantum states. These results show that geodesic evolutions are of interest for high-precision detections in systems coupled to an ancilla in the absence of measurements on the ancilla.

Monitoring a high--amplitude Delta Sct star for 152 days: discovery of 12 additional modes and modulation effects in the light curve of CoRoT 101155310

description: The detection of small-amplitude nonradial modes in high-amplitude Delta Sct (HADS) variables has been very elusive until at least five of them were detected in the light curve of V974 Oph obtained from ground-based observations. The combination of radial and nonradial modes has a high asteroseismic potential, thanks to the strong constraints we can put in the modelling. The continuous monitoring of ASAS 192647-0030.0=CoRoT 101155310 (P=0.1258 d, V=13.4) ensured from space by the CoRoT (Convection, Rotation and planetary Transits) mission constitutes a unique opportunity to exploit such potential. The 22270 CoRoT measurements were performed in the chromatic mode. They span 152 d and cover 1208 consecutive cycles. After the correction for one jump and the long-term drift, the level of the noise turned out to be 29 micromag. The phase shifts and amplitude ratios of the coloured CoRoT data, the HARPS spectra, and the period-luminosity relation were used to determine a self-consistent physical model. In turn, it allowed us to model the oscillation spectrum, also giving feedback on the internal structure of the star. In addition to the fundamental radial mode f1=7.949 c/d with harmonics up to 10f1, we detected 12 independent terms. Linear combinations were also found and the light curve was solved by means of 61 frequencies (smallest amplitude 0.10 mmag). The newest result is the detection of a periodic modulation of the f1 mode (triplets at +/-0.193 c/d centred on f1 and 2f1), discussed as a rotational effect or as an extension of the Blazhko effect to HADS stars. The physical model suggests that CoRoT 101155310 is an evolved star, with a slight subsolar metallic abundance, close to the terminal age main sequence. All the 12 additional terms are identified with mixed modes in the predicted overstable region.

description: Our recent results on {\em extended crystal PDE's} are generalized to PDE's in the category $\mathfrak{Q}_S$ of quantum supermanifolds. Then obstructions to the existence of global quantum smooth solutions for such equations are obtained, by using algebraic topologic techniques. Applications are considered in details to the quantum super Yang-Mills equations. Furthermore, our geometric theory of stability of PDE's and their solutions, is also generalized to quantum extended crystal PDE's. In this way we are able to identify quantum equations where their global solutions are stable at finite times. These results, are also extended to quantum singular (super)PDE's, introducing ({\em quantum extended crystal singular (super) PDE's}).

The cultural context of peer aggression in schools
Creators: name: Raia-Hawrylak, Alicia
Publisher: name: No Publisher Supplied
Year: 2019

description: This dissertation examines the organizational and group-level cultural processes that shape the context for peer interpersonal aggression in high schools. I use a mixed- methods approach to understand how behavioral norms in schools are formed at the organizational level of the school, and are communicated, enacted, and reshaped in small groups. The extent to which these norms vary in small groups, or classrooms, impacts the conditions for learning within them. Currently the majority of school victimization research focuses patterns of behavior at the school-wide level, without accounting for variation in micro-level contexts within the school. I situate the classroom as a key site of interactions between students. I use the School Climate Understanding and Building Aspirations (SCUBA) Survey to capture patterns of victimization and students’ perceptions and attitudes related to personal aspirations and school-wide norms. I conducted ethnographic observations in two high schools across a full academic year to observe grounded interactions over time. I also conducted in-depth interviews with students sampled from the observed classrooms. I argue that three main cultural factors shape the context for aggression in schools and classrooms. These are 1) academic and aspirational norms; 2) disciplinary norms and practices; and 3) the everyday practices that develop in classrooms. Variation in observed aggressive behavior between schools is primarily shaped by these cultural factors. Within school variation is primarily shaped by how these cultural elements are enacted within local classroom idiocultures, which are differentiated according to the classroom’s academic tracking level, the teacher, and the peer group. This study provides a grounded understanding of the cultural roots of aggressive behavior, and expands our understanding of how victimization varies across and within schools. Future efforts to reduce student interpersonal aggression and improve learning conditions should include measurement protocols and interventions focused on the key cultural factors identified, which take place at both the school-wide and classroom levels.

description: Tuberculosis (TB) is a communicable disease that is a major cause of ill health and a threat to health worldwide. Tuberculosis accounts for one of the top 10 causes of death worldwide and the leading cause of death from a single infectious agent which is M. tuberculosis (ranking above HIV/AIDS). If the patients are diagnosed on time and treated with first-line antibiotics for 6 months, most people who develop TB could be cured and onward transmission of infection could be reduced. Sustainable Development Goals Target 3.3 includes eliminating the TB epidemic by 2030. The End TB Strategy explains milestones (for 2025) and targets (for 2030 and 2035) for depletion in TB cases and deaths, 90% reduction in the number of TB deaths, and an 80% reduction in the TB prevalence rate compared with levels in 2015 are the targets for 2030. Evolution of Tuberculosis as Drug-resistant TB continues to be a public health threat. About half a million new cases of rifampicin-resistant TB (of which 78% had Multi-Drug-Resistant TB) were reported in 2018. India (27%), China (14%), and the Russian Federation (9%) bear the largest share of the global burden of TB patients. Diagnosis of MDR/RR-TB needs bacteriological confirmation of TB and testing for drug resistance using rapid molecular tests, sequencing technologies, or culture methods. Treatment requires a course of second-line drugs for at least 9 months and up to 20 months, held by counseling and monitoring for adverse events. Newer agents like Bedaquiline, Delamanid, Linezolid may be the key for the further treatment of MDR and XDR-TB although they are required to prove their safety in the treatment through proper monitoring and evaluations. The DUE study of TB medications helps in monitoring, evaluating, and make necessary modifications to the prescribing habits to achieve rational and cost-effective treatment. Although there are many challenges to tackle in front of the world if this has to be eliminated then the whole world has to come together and put its efforts towards ending it.

description: Interacting systems with $K$ driven particle species on a open chain or chains which are coupled at the ends to boundary reservoirs with fixed particle densities are considered. We classify discontinuous and continuous phase transitions which are driven by adiabatic change of boundary conditions. We build minimal paths along which any given boundary driven phase transition (BDPT) is observed and reveal kinetic mechanisms governing these transitions. Combining minimal paths, we can drive the system from a stationary state with all positive characteristic speeds to a state with all negative characteristic speeds, by means of adiabatic changes of the boundary conditions. We show that along such composite paths one generically encounters $Z$ discontinuous and $2(K-Z)$ continuous BDPTs with $Z$ taking values $0\leq Z\leq K$ depending on the path. As model examples we consider solvable exclusion processes with product measure states and $K=1,2,3$ particle species and a non-solvable two-way traffic model. Our findings are confirmed by numerical integration of hydrodynamic limit equations and by Monte Carlo simulations. Results extend straightforwardly to a wide class of driven diffusive systems with several conserved particle species.

description: The emergence of alternative stable states in forest systems has significant implications for the functioning and structure of the terrestrial biosphere, yet empirical evidence remains scarce. Here, we combine global forest biodiversity observations and simulations to test for alternative stable states in the presence of evergreen and deciduous forest types. We reveal a bimodal distribution of forest leaf types across temperate regions of the Northern Hemisphere that cannot be explained by the environment alone, suggesting signatures of alternative forest states. Moreover, we empirically demonstrate the existence of positive feedbacks in tree growth, recruitment and mortality, with trees having 4–43% higher growth rates, 14–17% higher survival rates and 4–7 times higher recruitment rates when they are surrounded by trees of their own leaf type. Simulations show that the observed positive feedbacks are necessary and sufficient to generate alternative forest states, which also lead to dependency on history (hysteresis) during ecosystem transition from evergreen to deciduous forests and vice versa. We identify hotspots of bistable forest types in evergreen-deciduous ecotones, which are likely driven by soil-related positive feedbacks. These findings are integral to predicting the distribution of forest biomes, and aid to our understanding of biodiversity, carbon turnover, and terrestrial climate feedbacks.

description: We describe Monte Carlo models for the dynamical evolution of the massive globular cluster 47 Tuc (NGC 104). The code includes treatments of two-body relaxation, most kinds of three- and four-body interactions involving primordial binaries and those formed dynamically, the Galactic tide, and the internal evolution of both single and binary stars. We arrive at a set of initial parameters for the cluster which, after 12Gyr of evolution, gives a model with a fairly satisfactory match to surface brightness and density profiles, the velocity dispersion profile, the luminosity function in two fields, and the acceleration of pulsars. Our models appear to require a relatively steep initial mass function for stars above about turnoff, with an index of about 2.8 (where the Salpeter mass function has an index of 2.35), and a relatively flat initial mass function (index about 0.4) for the lower main sequence. According to the model, the current mass is estimated at 0.9 million solar masses, of which about 34% consists of remnants. We find that primordial binaries are gradually taking over from mass loss by stellar evolution as the main dynamical driver of the core. Despite the high concentration of the cluster, core collapse will take at least another 20Gyr.

A primeira é a do gesto de publicação do autor, que, de acordo com o que propõe no seu último poema publicado, Conselho, tem por base a ideia de uma seleção apurada do que expõe ao mundo e de uma definição precisa dos moldes em que o faz. A segunda é a da intervenção pública, de índole crítica e sociopolítica, da qual não está ausente uma dimensão poética, performativa e provocatória. A terceira manifesta-se em textos de cariz biográfico por definição, como a sua correspondência, diários – alguns deles ficcionais, como o Livro do Desassossego ou A Educação do Estóico – ou apontamentos em que o literário se cruza com factos concretos da vida, como sejam a relação amorosa com Ofélia Queiroz, o desempenho de tarefas profissionais ou a dedicação a projetos de estudo, leitura e escrita.

description: Production of low-$p_T$ (soft) hadronic particles in high energy collisions constitutes a significant corner of special interests and problems, as the perturbative quantum chromodynamics (pQCD) does not work in this region. We have probed here into the nature of the light particle production in two symmetric nuclear collisions at two neighbouring energies with the help of two non-standard models. The results are found to be in good agreement with data. Despite this, as the models applied here are not intended to provide deep insights into the actual physical processes involved in such collisions, the phenomenological bounds and constraints which cannot be remedied for the present continue to exist.

description: We discuss large non-universality in the Higgs sector at high scale in supersymmetric theories, in the context of the Large Hadron Collider (LHC). In particular, we note that if ${m_{H_u}}^2-{m_{H_d}}^2$ is large and negative ($\simeq 10^6 {\rm ~GeV^2}$) at high scale, the lighter slepton mass eigenstates at the electroweak scale are mostly left chiral, in contrast to a minimal supergravity (mSUGRA) scenario. We use this feature to distinguish between non-universal Higgs masses (NUHM) and mSUGRA by two methods. First, we study final states with same-sign ditaus. We find that an asymmetry parameter reflecting the polarization of the taus provides a notable distinction. In addition, we study a charge asymmetry in the jet-lepton invariant mass distribution, arising from decay chains of left-chiral squarks leading to leptons of the first two families, which sets apart an NUHM scenario of the above kind.

description: While SUSY particles, if they exist at the TeV-scale, will be discovered at the Tevatron or the LHC, the determination of the SUSY-breaking scenario and its free parameters will require additional information, e.g. from a future International Linear Collider. We point out that such information, in particular on SUSY-particle mixing and the associated soft SUSY-breaking parameters, can also be obtained from measurements at existing or future polarized hadron colliders, since the polarization of initial-state quarks, transmitted through weak gauge bosons or squarks, can be strongly correlated with the helicity and gaugino/higgsino mixing of final-state sleptons, squarks, neutralinos and charginos.

description: The vertical wavenumber (VWN) characteristics during sudden stratospheric warming (SSW) events (2003–2016) is investigated for the first time using temperature observation of Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) on-board Thermosphere Ionosphere Mesosphere Energetics Dynamics (TIMED) satellite (for the altitude range of 20–70 km) and ERA-Interim reanalysis data (for the altitudes of 0.1–20 km). Highly negative VWN spectral slope value (approximately) of −4.82 (at 25° N, 77° E) and −4.41 (at 35° N, 77° E) at 40–50 km altitude is observed during the 2013 SSW event, a sort of which is not perceived in any other SSW events (2003–2016). The combined effect of planetary waves (PWs) with wavenumber 1 and 2 during 2013 SSW may be responsible for such distinctive observation near the peak temperature altitude. This study elicits the importance of polar vortex portraying that lower latitudes are affected if only the vortex splits and presents the first of its kind VWN characteristics during SSW events.

description: The report of a significant deviation of the CMB temperature anisotropies distribution from Gaussianity (soon after the public release of the WMAP data in 2003) has become one of the most solid WMAP anomalies. This detection grounds on an excess of the kurtosis of the Spherical Mexican Hat Wavelet coefficients at scales of around 10 degrees. At these scales, a prominent feature --located in the southern Galactic hemisphere-- was highlighted from the rest of the SMHW coefficients: the Cold Spot. This article presents a comprehensive overview related to the study of the Cold Spot, paying attention to the non-Gaussianity detection methods, the morphological characteristics of the Cold Spot, and the possible sources studied in the literature to explain its nature. Special emphasis is made on the Cold Spot compatibility with a cosmic texture, commenting on future tests that would help to give support or discard this hypothesis.

The elusive moral construct : an examination of remorse from a functional perspective
Creators: name: Baker, Alysha Taylor
Publisher: name: University of British Columbia

description: Little is known about the affective, cognitive, or functional underpinnings of remorse. The Dual Process Functional Theory (DPFT) of remorse offers a theoretical framework to build our understanding of remorse and the dual functions that it is hypothesized to serve: a self and social function. The self function refers to the distress experienced by the remorseful transgressor which contributes to the learning and/or reinforcement of social norms, helping ensure the individual does not commit the act again. Further, expressing remorse – most often through the means of an apology – communicates to others that the transgressor understands the moral violation and leads to relational repair (social function). Due to the social function of remorse, transgressors lacking remorse are highly motivated to feign it in hopes of garnering the benefits bestowed upon those perceived to be sincere. Given that it is frequently feigned, it is important to explore the manner in which remorse may be differentially communicated, and how accurately sincerity can be detected. The present dissertation tested the self and social functions proposed by the DPFT, and examined the ways in which genuine versus false remorse is appraised. Overall, findings supported both proposed functions of remorse in line with the DPFT. More specifically, the proposed cognitive (i.e., responsibility) and affective (i.e., distress) aspects of remorse were confirmed; however, given the low-stakes nature of the induction procedures, behavioural cues to remorse could not be identified. Further, the experience of remorse was associated with predicted outcomes that would communicate to a social group that the transgressor had learned from his/her actions. Interestingly, genuine and false remorse was differentiated by observers on various measures, including degree of remorsefulness, degree of sincerity, and likelihood of reoffending. Lastly, observers seemed well-attuned to the components of remorse in offenders’ statements in a sentencing hearing context, perceiving greater remorse when genuine facial expressions of distress and verbal descriptions of empathy for the victim were included.

description: This interdisciplinary study examined the relationship between bone density and drilling forces required during trans-pedicular access to the vertebra using fresh–frozen thoraco-lumbar vertebrae from two female body donors (A, B). Before and after biomechanical examination, samples underwent high-resolution CT-quantification of total bone density followed by software-based evaluation and processing. CT density measurements (n = 4818) were calculated as gray values (GV), which were highest in T12 for both subjects (GVmaxA = 3483.24, GVmaxB = 3160.33). Trans-pedicular drilling forces F (Newton N) were highest in L3 (FmaxB = 5.67 N) and L4 (FmaxA = 5.65 N). In 12 out of 13 specimens, GVs significantly (p < 0.001) correlated with force measurements. Among these, Spearman correlations r were poor in two lumbar vertebrae, fair in five specimens, and moderately strong in another five specimens, and highest for T11 (rA = 0.721) and L5 (rB = 0.690). Our results indicate that CT-based analysis of vertebral bone density acquired in anatomical specimens is a promising approach to predict the drilling force appearance as surrogate parameter of its biomechanical properties by e.g., linear regression analysis. The study may be of value as basis for biomechanical investigations to improve planning of the optimal trajectory and to define safety margins for drilling forces during robotic-assisted trans-pedicular interventions on the spine in the future.

description: We prove inverse theorems for the size of sumsets and the $L^q$ norms of convolutions in the discretized setting, extending to arbitrary dimension an earlier result of the author in the line. These results have applications to the dimensions of dynamical self-similar sets and measures, and to the higher dimensional fractal uncertainty principle. The proofs are based on a structure theorem for the entropy of convolution powers due to M.~Hochman.

description: We describe SR-POEM, a Galilean test of the weak equivalence principle, which is to be conducted during the free fall portion of a sounding rocket flight. This test of a single pair of substances is aimed at a measurement uncertainty of σ(η) < 10-16 after averaging the results of eight separate drops, each of 40 s duration. The weak equivalence principle measurement is made with a set of four laser gauges that are expected to achieve 0.1 pm/\sqrt{Hz}. We address the two sources of systematic error that are currently of greatest concern, magnetic force and electrostatic (patch effect) force on the test mass assemblies. The discovery of a violation (η\not= 0) would have profound implications for physics, astrophysics and cosmology.

description: If supersymmetry is relevant at the Fermi scale, the lack of any direct signal so far may require going beyond the Minimal Supersymmetric Standard Model. In this talk I briefly summarize a simple and concrete extension of the MSSM that takes these issues, including a way to address the flavour and the CP problems. In its fully natural range of parameters, the expected signals for LHC, dark matter and flavour physics are clear and generally quite different from the ones of the MSSM. Gauge coupling unification may be only approximate.

Existence and equilibration of global weak solutions to Hookean-type bead-spring chain models for dilute polymers

description: We show the existence of global-in-time weak solutions to a general class of coupled Hookean-type bead-spring chain models that arise from the kinetic theory of dilute solutions of polymeric liquids with noninteracting polymer chains. The class of models involves the unsteady incompressible Navier-Stokes equations in a bounded domain in two or three space dimensions for the velocity and the pressure of the fluid, with an elastic extra-stress tensor appearing on the right-hand side in the momentum equation. The extra-stress tensor stems from the random movement of the polymer chains and is defined by the Kramers expression through the associated probability density function that satisfies a Fokker-Planck-type parabolic equation, a crucial feature of which is the presence of a center-of-mass diffusion term. We require no structural assumptions on the drag term in the Fokker-Planck equation; in particular, the drag term need not be corotational. With a square-integrable and divergence-free initial velocity datum for the Navier-Stokes equation and a nonnegative initial probability density function for the Fokker-Planck equation, which has finite relative entropy with respect to the Maxwellian of the model, we prove the existence of a global-in-time weak solution to the coupled Navier-Stokes-Fokker-Planck system. It is also shown that in the absence of a body force, the weak solution decays exponentially in time to the equilibrium solution, at a rate that is independent of the choice of the initial datum and of the centre-of-mass diffusion coefficient.

description: Lime (Citrus aurantifolia Swingle) has a year round demand because of its utilization in food industry, indigenous medicine and domestic culinary. However, the production is highly seasonal. Hence, a study was conducted to evaluate the effect of cinnamon bark oil and hexanal incorporated bio-wax for extending its postharvest life. Lime cv. Local at optimum maturity was harvested and brought to the laboratory immediately. The bulk sample was divided into four replicated lots each containing 120 fruits. Two lots were dipped in the wax formulation for 45 s while the other two were kept as controls (no wax). Treated and control samples were stored in cold room (13°C ± 2°C; RH 90%) and ambient conditions (32°C ± 2°C; RH 70%) in plastic crates respectively. Evaluation of physicochemical attributes were conducted before treatment (day 0) and at 7-day intervals, until fruit exhibits limit of marketability. Bio-wax treatment decreased the rate of peel color deterioration and retarded the rate of increase in fruit firmness (P
