description: In this work we present a micromagnetic study of the performance potential of bit-patterned (BP) magnetic recording media via joint optimization of the design of the media and of the magnetic write heads. Because the design space is large and complex, we developed a novel computational framework suitable for parallel implementation on compute clusters. Our technique combines advanced global optimization algorithms and finite-element micromagnetic solvers. Targeting data bit densities of $4\mathrm{Tb}/\mathrm{in}^2$, we optimize designs for centered, staggered, and shingled BP writing. The magnetization dynamics of the switching of the exchange-coupled composite BP islands of the media is treated micromagnetically. Our simulation framework takes into account not only the dynamics of on-track errors but also of the thermally induced adjacent-track erasure. With co-optimized write heads, the results show superior performance of shingled BP magnetic recording where we identify two particular designs achieving write bit-error rates of $1.5\mathrm{x}10^{-8}$ and $8.4\mathrm{x}10^{-8}$, respectively. A detailed description of the key design features of these designs is provided and contrasted with centered and staggered BP designs which yielded write bit error rates of only $2.8\mathrm{x}10^{-3}$ (centered design) and $1.7\mathrm{x}10^{-2}$ (staggered design) even under optimized conditions.

description: The ATLAS collaboration has recently reported the results of a low-mass Higgs-boson search in the di-photon final state based on the full Run 2 data set. The results are based on an improved analysis w.r.t. the previous analysis, which included a part of the Run 2 data, with a substantially better sensitivity. The ``model-dependent'' search carried out by ATLAS shows an excess of events at a mass of about 95.4 GeV with a local significance of $1.7\,\sigma$. The results are compatible with a previously reported excess at the same mass, but somewhat higher significance of $2.9\,\sigma$, from the CMS collaboration, also based on the full Run 2 data set. Combining the two results (neglecting possible correlations) we find a signal strength of $\mu_{\gamma\gamma}^{\rm ATLAS+CMS} = 0.27^{+0.10}_{-0.09}$, corresponding to an excess of $3.2\,\sigma$. In this work, we investigate the implications of this result, updating a previous analysis based solely on the CMS Run 2 data. We demonstrate that the ATLAS/CMS combined di-photon excess can be interpreted as the lightest Higgs boson in a Two-Higgs doublet model that is extended by a complex singlet (S2HDM) of Yukawa types II and IV, while being in agreement with all other experimental and theoretical constraints.

description: Abstract

This study evaluates Bhina Bhakti Husada Hospital's Pharmacy Installation performance using the Balanced Scorecard. Financially, Inventory Turnover Ratio (ITOR), Growth Ratio on Sales, and Gross Profit Margin were assessed. ITOR increased (3.8 to 7.26), but remained below norms. Growth Ratio on Sales rose (10.2% to 46%), improving sales. Gross Profit Margin enhanced (23.4% to 35.2%), indicating better profitability. The customer perspective focused on service quality and satisfaction. Servqual analysis and Importance Performance Analysis (IPA) indicated service quality fell short of expectations, yet met ministry standards. Internally, dispensing time met service criteria, but drug availability (88.7% to 92%) suffered due to stock and procurement issues, though fast service was enabled by information systems. Training participation grew (80% to 85%), while employee turnover (21% to 30%) remained high, denoting retention challenges. Dominant delegative leadership style and positive organizational culture were noted. Overall, Pharmacy Installation showed financial growth, sales improvement, and efficiency. Challenges in customer satisfaction, drug availability, and employee retention suggest the need for hospital action to enhance performance and satisfaction.

description: Cosmological observations indicate that most of the matter in the Universe is Dark Matter. Dark Matter in the form of Weakly Interacting Massive Particles (WIMPs) can be detected directly, via its elastic scattering off target nuclei. Most current direct detection experiments only measure the energy of the recoiling nuclei. However, directional detection experiments are sensitive to the direction of the nuclear recoil as well. Due to the Sun's motion with respect to the Galactic rest frame, the directional recoil rate has a dipole feature, peaking around the direction of the Solar motion. This provides a powerful tool for demonstrating the Galactic origin of nuclear recoils and hence unambiguously detecting Dark Matter. Furthermore, the directional recoil distribution depends on the WIMP mass, scattering cross section and local velocity distribution. Therefore, with a large number of recoil events it will be possible to study the physics of Dark Matter in terms of particle and astrophysical properties. We review the potential of directional detectors for detecting and characterizing WIMPs.

description: Gravitational waves from a first-order cosmological phase transition, at temper-atures at the MeV-scale, would arguably be the most exciting explanation of the commonred spectrum reported by the NANOGrav collaboration, not the least because this would bedirect evidence of physics beyond the standard model. Here we perform a detailed analysisof whether such an interpretation is consistent with constraints on the released energy de-riving from big bang nucleosynthesis and the cosmic microwave background. We find that aphase transition in a completely secluded dark sector is strongly disfavoured with respect tothe more conventional astrophysical explanation of the putative gravitational wave signal interms of supermassive black hole binaries. On the other hand, a phase transition in a darksector that subsequently decays, before the time of neutrino decoupling, remains an intriguingpossibility to explain the data. From the model-building perspective, such an option is easilysatisfied for couplings with the visible sector that are small enough to evade current colliderand astrophysical constraints. The first indication that could eventually corroborate such aninterpretation, once the observed common red spectrum is confirmed as a nHz gravitationalwave background, could be the spectral tilt of the signal. In fact, the current data alreadyshow a very slight preference for a spectrum that is softer than what is expected from theleading astrophysical explanation.

description: We compare global predictions from the EAGLE hydrodynamical simulation, and two semi-analytic (SA) models of galaxy formation, L-GALAXIES and GALFORM. All three models include the key physical processes for the formation and evolution of galaxies and their parameters are calibrated against a small number of observables at $z\approx 0$. The two SA models have been applied to merger trees constructed from the EAGLE dark matter only simulation. We find that at $z\leq 2$, both the galaxy stellar mass functions for stellar masses $M_*<10^{10.5} M_{\odot}$ and the median specific star formation rates (sSFRs) in the three models agree to better than $0.4$~dex. The evolution of the sSFR predicted by the three models closely follows the mass assembly history of dark matter haloes. In both EAGLE and L-GALAXIES there are more central passive galaxies with $M_*<10^{9.5} M_{\odot}$ than in L-GALAXIES. This difference is related to galaxies that have entered and then left a larger halo and which are treated as satellites in GALFORM. In the range $010^{9.5} M_{\odot}$ differ in some instances by an order of magnitude, while the stellar mass-size relation in EAGLE is a factor of $\approx 2$ tighter than for the two SA models. Our results suggest the need for a revision of how SA models treat the effect of baryonic self-gravity on the underlying dark matter. The treatment of gas flows in the models needs to be revised based on detailed comparison with observations to understand in particular the evolution of the stellar mass-metallicity relation.

Berends-Giele recursion for double-color-ordered amplitudes
Creators: name: Mafra, Carlos R.
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Tree-level double-color-ordered amplitudes are computed using Berends--Giele recursion relations applied to the bi-adjoint cubic scalar theory. The standard notion of Berends--Giele currents is generalized to double-currents and their recursions are derived from a perturbiner expansion of linearized fields that solve the non-linear field equations. Two applications are given. Firstly, we prove that the entries of the inverse KLT matrix are equal to Berends--Giele double-currents (and are therefore easy to compute). And secondly, a simple formula to generate tree-level BCJ-satisfying numerators for arbitrary multiplicity is proposed by evaluating the field-theory limit of tree-level string amplitudes for various color orderings using double-color-ordered amplitudes.

description: Collaborative filtering-based recommender systems (RecSys) rely on learning representations for users and items to predict preferences accurately. Representation learning on the hypersphere is a promising approach due to its desirable properties, such as alignment and uniformity. However, the sparsity issue arises when it encounters RecSys. To address this issue, we propose a novel approach, graph-based alignment and uniformity (GraphAU), that explicitly considers high-order connectivities in the user-item bipartite graph. GraphAU aligns the user/item embedding to the dense vector representations of high-order neighbors using a neighborhood aggregator, eliminating the need to compute the burdensome alignment to high-order neighborhoods individually. To address the discrepancy in alignment losses, GraphAU includes a layer-wise alignment pooling module to integrate alignment losses layer-wise. Experiments on four datasets show that GraphAU significantly alleviates the sparsity issue and achieves state-of-the-art performance. We open-source GraphAU at https://github.com/YangLiangwei/GraphAU.

description: The naming game has become an archetype for linguistic evolution and mathematical social behavioral analysis. In the model presented here, there are $N$ individuals and $K$ words. Our contribution is developing a robust method that handles the case when $K = O(N)$. The initial condition plays a crucial role in the ordering of the system. We find that the system with high Shannon entropy has a higher consensus time and a lower critical fraction of zealots compared to low-entropy states. We also show that the critical number of committed agents decreases with the number of opinions and grows with the community size for each word. These results complement earlier conclusions that diversity of opinion is essential for evolution; without it, the system stagnates in the status quo [S. A. Marvel et al., Phys. Rev. Lett. 109, 118702 (2012)]. In contrast, our results suggest that committed minorities can more easily conquer highly diverse systems, showing them to be inherently unstable.

description: Ultracold atomic gases have recently become a driving force in few-body physics due to the observation of the Efimov effect. While initially observed in equal mass systems, one expects even richer few-body physics in the heteronuclear case. In previous experiments with ultracold mixtures of potassium and rubidium, an unexpected non-universal behavior of Efimov resonances was observed. In contrast, we measure the scattering length dependent three-body recombination coefficient in ultracold heteronuclear mixtures of $^{39}\mathrm{K}$-\87Rb and $^{41}\mathrm{K}$-\87Rb and do not observe any signatures of Efimov resonances for accessible scattering lengths in either mixture. Our results show good agreement with our theoretical model for the scattering dependent three-body recombination coefficient and reestablish universality across isotopic mixtures.

description: We here present a fresh approach to Frenkel excitons in cubic semiconductor crystals, with a special focus on the spin and spatial degeneracies of the electronic states. This approach uses a second quantization formulation of the problem in terms of creation operators for electronic states on all lattice sites -- their creation operators being true fermion operators in the tight-binding limit valid for semiconductors hosting Frenkel excitons. This operator formalism avoids using cumbersome ($6N_s$ x $6N_s$) Slater determinants -- 2 for spin, 3 for spatial degeneracy and $N_s$ for the number of lattice sites -- to represent state wave functions out of which the Frenkel exciton eigenstates are derived. A deep understanding of the tricky Coulomb physics that takes place in the Frenkel exciton problem, is a prerequisite for possibly diagonalizing this very large matrix analytically. This is done in three steps: (i) the first diagonalization, with respect to lattice sites, follows from transforming excitations on the $N_s$ lattice sites $\mathbf{R}_\ell$ into $N_s$ exciton waves $\mathbf{K}_n$, by using appropriate phase prefactors; (ii) the second diagonalization, with respect to spin, follows from the introduction of spin-singlet and spin-triplet electron-hole pair states, through the commonly missed sign change when transforming electron-absence operators into hole operators; (iii) the third diagonalization, with respect to threefold spatial degeneracy, leads to the splitting of the exciton level into one longitudinal and two transverse modes, that result from the singular interlevel Coulomb scattering in the small $\mathbf{K}_n$ limit.

description: To study body ownership and control, illusions that elicit these feelings in non-body objects are widely used. Classically introduced with the Rubber Hand Illusion, these illusions have been replicated more recently in virtual reality and by using brain-computer interfaces. Traditionally these illusions investigate the replacement of a body part by an artificial counterpart, however as brain-computer interface research develops it offers us the possibility to explore the case where non-body objects are controlled in addition to movements of our own limbs. Therefore we propose a new illusion designed to test the feeling of ownership and control of an independent supernumerary hand. Subjects are under the impression they control a virtual reality hand via a brain-computer interface, but in reality there is no causal connection between brain activity and virtual hand movement but correct movements are observed with 80% probability. These imitation brain-computer interface trials are interspersed with movements in both the subjects' real hands, which are in view throughout the experiment. We show that subjects develop strong feelings of ownership and control over the third hand, despite only receiving visual feedback with no causal link to the actual brain signals. Our illusion is crucially different from previously reported studies as we demonstrate independent ownership and control of the third hand without loss of ownership in the real hands.

description: The currently operating FASER experiment and the planned Forward Physics Facility (FPF) will detect a large number of neutrinos produced in proton-proton collisions at the LHC. In addition to neutrinos from pion and kaon decays, a significant contribution is expected from the decay of charmed hadrons, particularly for electron and tau neutrino flavors. In this work, we investigate two QCD formulations for the production of charm quarks in $pp$ collisions: the next-to-leading order collinear factorization and the $k_T$-factorization approach. We use state of the art fragmentation schemes to obtain hadron cross-sections and validate them against corresponding LHCb data. These calculations are then used to predict the forward neutrino flux from charm hadron decays. We further scrutinize the impact of varying QCD parameters, such as scales, the selection of parton distribution functions, and the modeling of fragmentation, on these predictions. We find that the measurement of forward neutrino flux will serve as a complementary tool to probe QCD dynamics and will offer valuable insights for astroparticle physics.

description: We consider two protocols for the measurement of the temporal correlation functions of a dichotomic variable Q appearing in Leggett-Garg type inequalities. The protocols measure solely whether Q has the same or different sign at the ends of a given time interval. They are inspired, in part, by a decoherent histories analysis of the two-time histories of Q although the protocols are ultimately expressed in macrorealistic form independent of quantum theory. The first type involves an ancilla coupled to the system with two sequential CNOT gates, and the two-time histories of the system are determined in a single final time measurement of the ancilla. It is non-invasive for special choices of initial system states and partially invasive for more general choices. Modified Leggett-Garg type inequalities which accommodate the partial invasiveness are discussed. The quantum picture of the protocol shows that for certain choices of primary system initial state the protocol is undetectable with respect to final system state measurements, although it is still invasive at intermediate times. This invasiveness can be reduced with different choices of ancilla states and the protocol is then similar in flavour to a weak measurement. The second type of protocol is based on the fact that the behaviour of Q over a time interval can be determined from knowledge of the dynamics together with a measurement of certain initial (or final) data. Its quantum version corresponds to the known fact that when sets of histories are decoherent, their probabilities may be expressed in terms of a record projector, hence the two-time histories in which Q has the same or different sign can be determined by a single projective measurement. The resulting protocol resembles the decay-type protocol proposed by Huelga and collaborators (which is non-invasive but requires a stationarity assumption).

description: Identical particle correlations at fixed multiplicity are considered by means of quantum canonical ensemble of finite systems. We calculate one-particle momentum spectra and two-particle Bose-Einstein correlation functions in the ideal gas by using a recurrence relation for the partition function. Within such a model we investigate the validity of the thermal Wick's theorem and its applicability for decomposition of the two-particle distribution function. The dependence of the Bose-Einstein correlation parameters on the average momentum of the particle pair is also investigated. Specifically, we present the analytical formulas that allow one to estimate the effect of suppressing the correlation functions in a finite canonical system. The results can be used for the femtoscopy analysis of the A+A and p+p collisions with selected (fixed) multiplicity.

description: We explore the momentum analyticity of the static transverse polarization tensor of a 2+1 dimensional holographic superconductor in its normal phase with a nonzero chemical potential, aiming at finding the holographic counterpart of the singularities underlying the Friedel-like oscillations of an ordinary field theory. We prove that the polarization tensor is a meromorphic function with an infinite number of poles located on the complex momentum plane off real axis. With the aid of the WKB approximation these poles are found to lies asymptotically along two straight lines parallel to the imaginary axis for a large momentum magnitude. The similarity between the holographic Green's function and that of an weakly coupled ordinary field theory (e.g., 2+1 dimensional QED) regarding the location of the momentum singularities offers further support to the validity of the gauge/gravity duality.

Making-Kompetenzen

description: Das folgende Making-Kompetenz-Framework besteht aus 24 Kompetenzen. Jede Kompetenz beinhaltet in Anlehnung an das Kompetenzverständnis von Weinert (2001) und an das Making-Verständnis von Maurer/Ingold (2023) Wissensbestände, Haltungen und Fertigkeiten, die im Framework jeweils in sechs Indikatoren abgebildet sind. Auf eine systematische Hierarchisierung der Indikatoren wird verzichtet, da Making-Aktivitäten gegenstandsbedingt über kognitive Operationen hinausgehen. Stattdessen sind die Formulierungen an Schüler:innen der Mittelstufe adressiert, so dass diese in Lage sind, anhand der Indikatoren auch Selbsteinschätzungen vorzunehmen. Bei den erstgenannten Indikatoren in jeder Kompetenz handelt es sich in der Regel um Wissensaspekte. Die nachfolgenden Indikatoren sind eher auf der Ebene von Haltungen und Fertigkeiten zu verorten. Die Wissensbestände sind jeweils Bestandteil und Voraussetzung für den Kompetenzerwerb, müssen aber nicht zwingend zuerst erworben werden. Die Einteilung in Personale Kompetenzen, Soziale Kompetenzen, Methodenkompetenzen und Fachkompetenzen orientiert sich an der Klassifizierung in gängigen Lehr-und Bildungsplänen.
Spacetime Quanta? : The Discrete Spectrum of a Quantum Spacetime Four-Volume Operator in Unimodular Loop Quantum Cosmology
Creators: name: Bunao, Joseph
Publisher: name: arXiv
Year: 2016
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: This study considers the operator $\hat{T}$ corresponding to the classical spacetime four-volume $\tilde{T}$ (on-shell) of a finite patch of spacetime in the context of Unimodular Loop Quantum Cosmology for the homogeneous and isotropic model with flat spatial sections and without matter sources. Since the spacetime four-volume is canonically conjugate to the cosmological "constant", the operator $\hat{T}$ is constructed by solving its canonical commutation relation with $\hatΛ$ - the operator corresponding to the classical cosmological constant on-shell $\tildeΛ$. This conjugacy, along with the action of $\hat{T}$ on definite volume states reducing to $\tilde{T}$, allows us to interpret that $\hat{T}$ is indeed a quantum spacetime four-volume operator. The discrete spectrum of $\hat{T}$ is calculated by considering the set of all $τ$'s where the eigenvalue equation has a solution $Φ_τ$ in the domain of $\hat{T}$. It turns out that, upon assigning the maximal domain $D(\hat{T})$ to $\hat{T}$, we have $Φ_τ\in D(\hat{T})$ for all $τ\in\mathbb{C}$ so that the spectrum of $\hat{T}$ is purely discrete and is the entire complex plane. A family of operators $\hat{T}^{(b_0,ϕ_0)}$ was also considered as possible self-adjoint versions of $\hat{T}$. They represent the restrictions of $\hat{T}$ on their respective domains $D(\hat{T}^{(b_0,ϕ_0)})$ which are just the maximal domain with additional quasi-periodic conditions. Their possible self-adjointness is motivated by their discrete spectra only containing real and discrete numbers $τ_m$ for $m=0,\pm1,\pm2,...$.

Surveying Residential Burglaries: A Case Study of Local Crime Measurement

description: We consider the problem of estimating the incidence of residential burglaries that occur over a well-defined period of time within the 10 most populous cities in North Carolina. Our analysis typifies some of the general issues that arise in estimating and comparing local crime rates over time and for different cities. Typically, the only information we have about crime incidence within any particular city is what that city's police department tells us, and the police can only count and describe the crimes that come to their attention. To address this, our study combines information from police-based residential burglary counts and the National Crime Victimization Survey to obtain interval estimates of residential burglary incidence at the local level. We use those estimates as a basis for commenting on the fragility of between-city and over-time comparisons that often appear in both public discourse about crime patterns.
