description: Stars of spectral types O and B produce neutron stars (NSs) after supernova explosions. Most of NSs are strongly magnetised including normal radio pulsars with $B \propto 10^{12}$ G and magnetars with $B\propto 10^{14}$ G. A fraction of 7-12 per cent of massive stars are also magnetised with $B\propto 10^3$ G and some are weakly magnetised with $B\propto 1$ G. It was suggested that magnetic fields of NSs could be the fossil remnants of magnetic fields of their progenitors. This work is dedicated to study this hypothesis. First, we gather all modern precise measurements of surface magnetic fields in O, B and A stars. Second, we estimate parameters for log-normal distribution of magnetic fields in B stars and found $μ_B = 2.83\pm 0.1$ $\log_{10}$ (G), $σ_B=0.65\pm 0.09$ for strongly magnetised and $μ_B = 0.14\pm 0.5$ $\log_{10}$ (G), $σ=0.7_{-0.27}^{+0.57}$ for weakly magnetised. Third, we assume that the magnetic field of pulsars and magnetars have $2.7$ DEX difference in magnetic fields and magnetars represent 10 per cent of all young NSs and run population synthesis. We found that it is impossible to simultaneously reproduce pulsars and magnetars populations if the difference in their magnetic fields is 2.7 DEX. Therefore, we conclude that the simple fossil origin of the magnetic field is not viable for NSs.

description: It has been demonstrated that quantum vacuum energy gravitates according to the equivalence principle, at least for the finite Casimir energies associated with perfectly conducting parallel plates. We here add further support to this conclusion by considering parallel semitransparent plates, that is, delta-function potentials, acting on a massless scalar field, in a spacetime defined by Rindler coordinates (tau,x,y,xi). Fixed xi in such a spacetime represents uniform acceleration. We calculate the force on systems consisting of one or two such plates at fixed values of xi. In the limit of large Rindler coordinate xi (small acceleration), we recover (via the equivalence principle) the situation of weak gravity, and find that the gravitational force on the system is just Mg, where g is the gravitational acceleration and M is the total mass of the system, consisting of the mass of the plates renormalized by the Casimir energy of each plate separately, plus the energy of the Casimir interaction between the plates. This reproduces the previous result in the limit as the coupling to the delta-function potential approaches infinity.

description: We report that Ly$α$-emitting galaxies (LAEs) may not faithfully trace the cosmic web of neutral hydrogen (HI), but their distribution is likely biased depending on the viewing direction. We calculate the cross-correlation (CCF) between galaxies and Ly$α$ forest transmission fluctuations on the near and far sides of the galaxies separately, for three galaxy samples at $z\sim2$: LAEs, [OIII] emitters (O3Es), and continuum-selected galaxies. We find that only LAEs have anisotropic CCFs, with the near side one showing lower signals up to $r=3-4~h^{-1}$ comoving Mpc. This means that the average HI density on the near side of LAEs is lower than that on the far-side by a factor of $2.1$ under the Fluctuating Gunn-Peterson Approximation. Mock LAEs created by assigning Ly$α$ equivalent width ($EW_\text{Ly$α$}^\text{obs}$) values to O3Es with an empirical relation also show similar, anisotropic CCFs if we use only objects with higher $EW_\text{Ly$α$}^\text{obs}$ than a certain threshold. These results indicate that galaxies on the far side of a dense region are more difficult to be detected ("hidden") in Ly$α$ because Ly$α$ emission toward us is absorbed by dense neutral hydrogen. If the same region is viewed from a different direction, a different set of LAEs will be selected as if galaxies are playing hide-and-seek using HI gas. Care is needed when using LAEs to search for overdensities.

description: Il tema delle trasformazioni epocali della religiosità, che Guardini affronta nel testo Das Ende der Neuzeit, non deve essere frettolosamente interpretato o semplicemente letto come una teoria della secolarizzazione. Esso intende piuttosto porre la questione ad un livello più profondo: quello del rapporto tra storia e libertà umana. In effetti è in questa prospettiva che il testo di Guardini è stato recepito nell’ambito della scuola fenomenologica friburghese, come dimostra l’originale teoria della storia di Max Müller.

description: We show three-dimensional magnetohydrodynamical simulations of core collapse supernova in which the progenitor has magnetic fields inclined to the rotation axis. The simulations employed a simple empirical equation of state in which the pressure of degenerate gas is approximated by piecewise polytropes for simplicity. Neither energy loss due to neutrino is taken into account for simplicity. The simulations start from the stage of dynamical collapse of an iron core. The dynamical collapse halts at $ t $ = 189 ms by the pressure of high density gas and a proto-neutron star (PNS) forms. The evolution of PNS was followed about 40 milli-seconds in typical models. When the initial rotation is mildly fast and the initial magnetic fields are mildly strong, bipolar jets are launched from an upper atmosphere ($ r \sim 60 {\rm km} $) of the PNS. The jets are accelerated to $ \sim 3 \times 10 ^4 $ km s$^{-1}$, which is comparable to the escape velocity at the foot point. The jets are parallel to the initial rotation axis. Before the launch of the jets, magnetic fields are twisted by rotation of the PNS. The twisted magnetic fields form torus-shape multi-layers in which the azimuthal component changes alternately. The formation of magnetic multi-layers is due to the initial condition in which the magnetic fields are inclined with respect to the rotation axis. The energy of the jet depends only weakly on the initial magnetic field assumed. When the initial magnetic fields are weaker, the time lag is longer between the PNS formation and jet ejection. It is also shown that the time lag is related to the Alfvén transit time. Although the nearly spherical prompt shock propagates outward in our simulations, it is ...

The Impact of COVID-19 on the Transition to School Among African American Children with Disabilities
Creators: name: Brown-Hollie, Jasmine Patrice
Publisher: name: University of Illinois at Chicago
Year: 2024

description: The coronavirus (COVID-19) pandemic drastically impacted children's educational experiences worldwide, as children and families were forced to navigate constant and unexpected changes all at once. Typical educational transitions for children were disrupted, like the transition to school, which can be seen as a critical period in a child’s education and can influence their later educational and life trajectories. Prior to the pandemic, African American children with disabilities have been shown to be less prepared for the transition to school, leading to an educational gap when compared to their White counterparts. Consequently, there is little known knowledge of how African American families of children with disabilities are preparing their children for this important transition. As the transition to school is essential to the educational outcomes of African American children with disabilities, this study sought to explore how the pandemic impacted the school readiness process for African American children with disabilities and delays during a time of heightened stress and crisis for families and educators.

description: We study theoretically a novel drug delivery system that utilizes the overexpression of certain proteins in cancerous cells for cell specific chemotherapy. The system consists of dendrimers conjugated with "keys" (ex: folic acid) which "key-lock" bind to particular cell membrane proteins (ex: folate receptor). The increased concentration of "locks" on the surface leads to a longer residence time for the dendrimer and greater incorporation into the cell. Cooperative binding of the nanocomplexes leads to an enhancement of cell specificity. However, both our theory and detailed analysis of in-vitro experiments indicate that the degree of cooperativity is kinetically limited. We demonstrate that cooperativity and hence the specificity to particular cell type can be increased by making the strength of individual bonds weaker, and suggest a particular implementation of this idea. The implications of the work for optimizing the design of drug delivery vehicles are discussed.

description: The preliminary qualitative phytochemical screening, quantitative alkaloids, flavonoids and saponins and antioxidant activity have been carried out on both the n-hexane, HCP and the ethyl acetate, ECP extracts obtained from honeybee residue collected from Chikun in Kaduna State, Nigeria. The crude honeybee was strained and its residue subjected to both phytochemical and antioxidant profiling using established procedures. The qualitative Phytochemical screening revealed the presence of both steroids and terpeniods in HCP while alkaloids, flavonoids and saponins were present in addition in ECP. Quantitatively, alkaloids (0.89±0.00 mg/g AE), flavonoids (9.69±0.40 mg/g RE) and saponins (1.08±0.08 mg/g DE) were evaluated in ECP. Both extracts exhibited antioxidant activity in a concentration dependent gradient. Crude honeybee residue is an alternative source of phytochemicals with relevance therapeutical potentials.

description: n La fine dell'epoca moderna (1950) Romano Guardini, filosofo e teologo, anticipa l'intero dibattito sulla post-modernità. Egli delinea i confini della modernità e pone in evidenza lo smarrimento dell'uomo dinnanzi al riaprirsi della domanda sull'origine dell'esistenza. Non è la logica stessa della modernità – si domanda Guardini – a metter capo ad un inaspettato ritorno del caos, interno ed esterno? «L'uomo sta nuovamente di fronte al caos...». Questo lavoro, in un armonico insieme di studiosi dalle differenti prospettive, propone una riflessione del Guardini critico della modernità e della trasformazione del concetto di “religiosità” che si è avuta durante la post-modernità. Esso vuole essere il tentativo di portare il lettore a riflettere su uno dei maggiori rischi dei tempi attuali, e cioè lo smarrimento di quella religiosità che ha reso tale l'arte e la cultura dell'Occidente, e che costituisce il terreno comune di una società in cui la libertà e la dignità umana non sono più valori da guadagnare, ma l'orizzonte in cui è possibile costruire e progredire. Proponiamo questo passo a introduzione dell'opera.

description: Temperature dependent (4K-300K) photoluminescence and transmission spectra are analyzed to study the effect of changing the different components of a perovskite compound, be it A, B, or X. Four different films are compared: FAMAPbSnI3, FAPbI3, FAMAPbI3, and FAPbBr3. The low temperature results highlight the changes that occur especially, underlying ones that are easily masked at room temperature. The overall Stokes shift is of similar magnitude at room temperature for the 3 Pb only based samples. This is governed by the interaction strength GammaLO, phonon energy ELO, and the exciton binding energy Eex. One exception to this behavior is the Sn-based FAMAPbSnI3 film which shows a lack of Stokes shift between the absorption and photoluminescence. However,the strong absorption (more than 100 meV) below the band gap is indicative of an excitonic feature that has a large density of states. Transient absorption measurements confirm the trends observed in continuous wave (CW) measurements, the 3 Pb only films all show the convolution of an excitonic feature within 20 meV of the band gap as a contributing factor to the photobleach along with a region of high energy PIA. However, the behavior for the Sn-based film is notably different (just as in the CW measurements) with an unusual low energy PIA and a lack of high energy PIA. The large low energy PIA is attributed to the large sub band gap absorption observed in the CW transmission/absorption measurements. Notably regardless of interchanging components, the slow cooling of carriers in metal-halide perovsites shows little effect of GammaLO, ELO, and Eex. As such, here it is proposed: while the initial cooling of carriers is attributed to LO phonons, the overall cooling of carriers is dominated by the intrinsic low thermal conductivity of all metal-halide perovskites which limits the dissipation of acoustic phonons in these systems.

description: In this work, we investigate the detailed theory of the supercoupling, anomalous tunneling effect, and field confinement originally identified in [M. Silveirinha, N. Engheta, Phys. Rev. Lett. 97, 157403, (2006)], where we demonstrated the possibility of using materials with permittivity near zero to drastically improve the transmission of electromagnetic energy through a narrow irregular channel with very subwavelength transverse cross-section. Here, we present additional physical insights, describe new applications of the tunneling effect in relevant waveguide scenarios (e.g., the "perfect" or "super" waveguide coupling), study the effect of metal losses in the metallic walls, and the possibility of using epsilon-near zero materials to confine energy in a subwavelength cavity with gigantic field enhancement. In addition, we systematically study the propagation of electromagnetic waves through narrow channels filled with anisotropic epsilon-near zero materials. It is demonstrated that these materials may have interesting potentials, and that for some particular geometries the reflectivity of the channel is independent of the specific dimensions or parameters of epsilon-near zero transition. We also describe several realistic metamaterial implementations of the studied problems, based on standard metallic waveguides, microstrip line configurations, and wire media.

description: We examine the phenomenology of the scalar fields in weak and Higgs sectors of minimal $R$-symmetric models, in particular the 'swino' and 'sbino', the scalar partners to the chiral fields that marry the electroweak gauge bosons in Dirac gaugino models. These fields are in adjoint representations of $SU(2)$ and $U(1)$ and have both $CP$-even and $CP$-odd components. The interactions of these new states are summarized, and decay widths are computed analytically to one loop order. We discuss the tree level contributions of these new states to the mass spectrum of MSSM sfermions. We also explore production cross sections and decay signatures at colliders for several chosen benchmarks. We find that large regions of parameter space are unconstrained by present collider data.

description: We analyze the Hawking radiation process due to collapsing configurations in the presence of superluminal modifications of the dispersion relation. With such superluminal dispersion relations, the horizon effectively becomes a frequency-dependent concept. In particular, at every moment of the collapse, there is a critical frequency above which no horizon is experienced. We show that, as a consequence, the late-time radiation suffers strong modifications, both quantitative and qualitative, compared to the standard Hawking picture. Concretely, we show that the radiation spectrum becomes dependent on the measuring time, on the surface gravities associated with different frequencies, and on the critical frequency. Even if the critical frequency is well above the Planck scale, important modifications still show up.

description: Collective spin operators for symmetric multi-quDit (namely, identical $D$-level atom) systems generate a U$(D)$ symmetry. We explore generalizations to arbitrary $D$ of SU(2)-spin coherent states and their adaptation to parity (multicomponent Schrödinger cats), together with multi-mode extensions of NOON states. We write level, one- and two-quDit reduced density matrices of symmetric $N$-quDit states, expressed in the last two cases in terms of collective U$(D)$-spin operator expectation values. Then we evaluate level and particle entanglement for symmetric multi-quDit states with linear and von Neumann entropies of the corresponding reduced density matrices. In particular, we analyze the numerical and variational ground state of Lipkin-Meshkov-Glick models of $3$-level identical atoms. We also propose an extension of the concept of SU(2) spin squeezing to SU$(D)$ and relate it to pairwise $D$-level atom entanglement. Squeezing parameters and entanglement entropies are good markers that characterize the different quantum phases, and their corresponding critical points, that take place in these interacting $D$-level atom models.

description: Massive access is one of the main use cases of beyond 5G (B5G) wireless networks and massive MIMO is a key technology for supporting it. Prior works studied massive access in the co-located massive MIMO framework. In this paper, we investigate the activity detection in grant-free random access for massive machine type communications (mMTC) in cell-free massive MIMO network. Each active device transmits a pre-assigned non-orthogonal pilot sequence to the APs and the APs send the received signals to a central processing unit (CPU) for joint activity detection. We formulate the maximum likelihood device activity detection problem and provide an algorithm based on coordinate descent method having affordable complexity. We show that the cell-free massive MIMO network can support low-powered mMTC devices and provide a broad coverage.

description: Talagrand's positivity principle states that one can slightly perturb a Hamiltonian in the Sherrington-Kirkpatrick model in such a way that the overlap of two configurations under the perturbed Gibbs' measure will become typically nonnegative. In this note we observe that abstracting from the setting of the SK model only improves the result and does not require any modifications in Talagrand's argument. In this version, for example, positivity principle immediately applies to the setting of Aizenman-Sims-Starr interpolation. Also, abstracting from the SK model improves the conditions in the Ghirlanda-Guerra identities and as a consequence results in a perturbation of smaller order necessary to ensure positivity of the overlap.

Applicability of some organizational behavior theories in the People's Republic of China

description: The recent economic and political developments in China, as a result of the open-door policy and commitment by Chinese leaders to attaining the national goals, have made it inevitable for Western theories of management to be introduced to Chinese managers. Transferability of these theories has become an important concern of the managers and scholars in management. The current study was thus intended to serve as a preliminary attempt to look into the applicability of some management theories in China's industries. The focal attention has been given to evaluation of theories in the areas of motivatoin and leadership. The selected theories of motivation include Maslow's need hierarchy theory, equity theory, and expectancy theory. Vroom and Yetton decision tree and Hollander's idiosyncracy credit theory of leadership have been chosen to provide discussion on leader behaviors. The basic assumptions and boundary conditions have been identified and examined in the context of Chinese cultural, social, and political systems. It was found that most theories evaluated are not applicable in China their preconditions for application are not met to the extent that managerial implications derived from them can create effects intended to enhance managerial effectiveness. Such inapplicability is the result of a wide range of differences in perception of man's role in society, value systems, and the corresponding organizational processes between Western and Chinese cultures.

description: Core temperature (TC) changes, alongside exercise, affect hemodynamic responses across different conduit and microvascular beds. This study investigated impacts of ecologically valid environmental heat and exercise exposures on cerebral, skin and retinal vascular responses by combining physiological assessments alongside computational fluid dynamics (CFD) modeling. Young, healthy participants (n = 12) were exposed to environmental passive heating (PH), and heated exercise (HE) (ergometer cycling), in climate-controlled conditions (50 mins, 40°C, 50% relative humidity) while maintaining upright posture. Blood flow responses in the common carotid (CCA), internal carotid (ICA) and central retinal (CRA) arteries were assessed using Duplex ultrasound, while forearm skin microvascular blood flow responses were measured using optical coherence tomography angiography. Three-dimensional retinal hemodynamics (flow and pressure) were calculated via CFD simulation, enabling assessment of wall shear stress (WSS). TC rose following PH (+0.2°C, p = 0.004) and HE (+1.4°C, p < 0.001). PH increased skin microvascular blood flow (p < 0.001), whereas microvascular CRA flow decreased (p = 0.038), despite unchanged ICA flow. HE exacerbated these differences, with increased CCA flow (p = 0.007), unchanging ICA flow and decreased CRA flow (p < 0.001), and interactions between vascular (CCA vs. ICA p = 0.018; CCA vs. CRA p = 0.004) and microvascular (skin vs. retinal arteriolar p < 0.001) territories. Simulations revealed patterns of WSS and lumen pressure that uniformly decreased following HE. Under ecologically valid thermal challenge, different responses occur in distinct conduit and microvascular territories, with blood flow distribution favoring systemic thermoregulation, while flow may redistribute within the brain.

description: The following article is going to discuss the Intelligent Design movement, which was born in the United States during the last decade of the twentieth century and became famous because of its critical statements toward Evolutionism. The main goal of this article is to expose, in a neutral way, the history of the movement, its topics, its supporters and critics. In the beginning, the article deals with the precursors of the Intelligent Design and the history of the Discovery Institute, organization which the exponents of the movement are part of. It follows the analysis of the reception of the Intelligent Design in Italy. The subsequent topic of the article is the thoughts of the most eminent members of the Discovery Institute: William Dembski, Michael Behe, Stephen Meyer and Douglas Axe. The final part focuses on the critics of the Intelligent Design, in particular the philosophers of science Telmo Pievani and Benjamin Jantzen.

description: A resonant state at $3.21^{+0.12}_{-0.04}$\,MeV, located just above the one-neutron separation threshold, was observed for the first time in $^{12}$Be from the $^{11}$Be\,$(d,p)^{12}$Be one-neutron transfer reaction in inverse kinematics. This state is assigned a spin-parity of $0^-$, according to the distorted-wave Born approximation (DWBA) and decay-width analysis. Gamow coupled-channel (GCC) and Gamow shell-model (GSM) calculations show the importance of the continuum-coupling, which dramatically influences the excitation energy and ordering of low-lying states. Various exotic structures associated with cross-shell intruding configurations in $^{12}$Be and in its isotonic nucleus $^{11}$Li are comparably discussed.
ente e il niente. La religione tra sacro e profano

description: In this essay I interpret the holy as an “absolute alterity” in relation to the profane. Therefore, if the profane correspond to the “world of things”, the holy correspond to “nothing”. Along their history, human beings have been trying to find a way to overcome such a disturbing “nothing”. Hence, religion is interpreted as a technique that is useful in defending humanity from the holy by concealing it through a fictional world.

description: If we distribute n qubits between two parties, which quantum pure states and distributions of qubits would allow all-versus-nothing (or Greenberger-Horne-Zeilinger-like) proofs of Bell's theorem using only single-qubit measurements? We show a necessary and sufficient condition for the existence of these proofs for any number of qubits, and provide all distinct proofs up to n=7 qubits. Remarkably, there is only one distribution of a state of n=4 qubits, and six distributions, each for a different state of n=6 qubits, which allow these proofs.

Системный анализ эвфемистических номинаций в политической сфере позволил выявить когнитивную модель - фрейм ОБОРОНА / DEFENCE, который активируется при описании средствами массовой информации ряда актуальных проблем, формирующих политическую повестку дня в выше указанный период времени, а также осуществить реконструкцию его субфреймов и их слотов, вербальные средства репрезентации которых представлены эвфемистическими номинациями. Использование эвфемистических номинаций, актуализирующих данную когнитивную модель становится эффективным средством манипулятивного воздействия на массового адресата, способствующим выполнению прагматической задачи создания положительного образа «своих» в политическом медиадискурсе.

description: Copper (Cu) is a necessary micro-element and plays important roles in many biochemical processes. However, excessive Cu intake can lead to multi-organ toxicity, especially in the spleen. To gain further insights into the specific mechanisms of splenic toxicity associated with Cu-induced metabolic disorders, 192 one-day-old chickens were selected and randomly divided into four groups for this study. The broilers were fed with diets containing Cu at final concentrations of 11, 110, 220 and 330 mg/kg for 49 days. The results showed that high dietary Cu caused nuclear shrinkage and mitochondrial vacuolization in the spleen and induced splenic injury through regulating the glutathione metabolism, pentose and gluconate interconversion, tryptophan metabolism and glycerophosphatidylcholine metabolism pathways. Moreover, excess Cu could disorder the mitochondrial dynamics via up-regulating the levels of Drp1, Parkin PINK1, and Dynein, and down-regulating the levels of Mfn1, Mfn2 and OPA1. Cu treatment increased the levels of LC3A, LC3B, mTOR, Beclin1, and ATG5 and decreased the p62 level to promote autophagy of splenocytes. Meanwhile, a high dose of Cu promoted splenocyte apoptosis by increasing the levels of p53, BAK-1, Bax, Cyt C and Caspase-3 and decreasing the level of Bcl-2. These results demonstrated that high dietary Cu could cause autophagy and apoptosis via inducing metabolic disturbances and disordering mitochondrial dynamics in the spleen of broiler chicken.

description: A constellation of $N=d-1$ Majorana stars represents an arbitrary pure quantum state of dimension $d$ or a permutation-symmetric state of a system consisting of $n$ qubits. We generalize the latter construction to represent in a similar way an arbitrary symmetric pure state of $k$ subsystems with $d$ levels each. For $d\geq 3$, such states are equivalent, as far as rotations are concerned, to a collection of various spin states, with definite relative complex weights. Following Majorana's lead, we introduce a multiconstellation, consisting of the Majorana constellations of the above spin states, augmented by an auxiliary, "spectator" constellation, encoding the complex weights. Examples of stellar representations of symmetric states of four qutrits, and two spin-$3/2$ systems, are presented. We revisit the Hermite and Murnaghan isomorphisms, which relate multipartite states of various spins, number of parties, and even symmetries. We show how the tools introduced can be used to analyze multipartite entanglement and to identify optimal quantum rotosensors, i.e., pure states which are maximally sensitive to rotations around a specified axis, or averaged over all axes.

description: The in-medium spectral functions of $ρ$ and $ω$ mesons and the broadening of the nucleon resonances at finite baryon density are calculated self-consistently by combining a resonance dominance model for the vector meson production with an extended vector meson dominance model. The influence of the in-medium modifications of the vector meson properties on the dilepton spectrum in heavy-ion collisions is investigated. The dilepton spectrum is generated for the C+C reaction at 2.0$A$ GeV and compared with recent HADES Collaboration data. The collision dynamics is then described by the Tübingen relativistic quantum molecular dynamics transport model. We find that an iterative calculation of the vector meson spectral functions that takes into account the broadening of the nucleon resonances due to their increased in-medium decay branchings is convergent and provides a reasonable description of the experimental data in the mass region $0.45\leq M \leq 0.75$ GeV. On the other side, the theoretical calculations slightly underestimate the region $m_π\leq M \leq 0.4$ GeV. Popular in-medium scenarios such as a schematic collisional broadening and dropping vector mesons masses are discussed as well.
