description: Entangled states of rotating, trapped ultracold bosons form a very promising scenario for quantum metrology. In order to employ such states for metrology, it is vital to understand their detailed form and the enhanced accuracy with which they could measure phase, in this case generated through rotation. In this work we study the rotation of ultracold bosons in an asymmetric trapping potential beyond the lowest Landau level (LLL) approximation. We demonstrate that whilst the LLL can identify reasonably the critical frequency for a quantum phase transition and entangled state generation, it is vital to go beyond the LLL to identify the details of the state and quantify the quantum Fisher information (which bounds the accuracy of the phase measurement). We thus identify a new parameter regime for useful entangled state generation, amenable to experimental investigation.

description: We take an analytic approach to the CFT bootstrap, studying the 4-pt correlators of d > 2 dimensional CFTs in an Eikonal-type limit, where the conformal cross ratios satisfy |u| << |v| < 1. We prove that every CFT with a scalar operator ϕmust contain infinite sequences of operators O_{τ,l} with twist approaching τ-> 2Δ_ϕ+ 2n for each integer n as l -> infinity. We show how the rate of approach is controlled by the twist and OPE coefficient of the leading twist operator in the ϕx ϕOPE, and we discuss SCFTs and the 3d Ising Model as examples. Additionally, we show that the OPE coefficients of other large spin operators appearing in the OPE are bounded as l -> infinity. We interpret these results as a statement about superhorizon locality in AdS for general CFTs.

description: OER is a distinct way of learning in the modern era, without any geographical barriers and money. There are two types of OER depending on how it approaches its user, Open Course Ware (OCW) and MOOCs. In India, e-PG Pathshala is such an innovation maintained by UGCINFLIBNET and funded by MHRD. As part of its National Education Mission through ICT (NME-ICT), it is a wide e-learning platform in terms of its subject material and breadth of use as well. In this context, the present study is an attempt to assess the status of e-content modules of e-PG Pathshala in the different subject discipline. The findings of the study identified that among the two broad subject category, AHSS field occupied 62% of total uploaded modules and rest 38% covered by STEMM. In consecutive divisions of the subject field into five major subject discipline reveals that “Social Sciences” and “Arts, Humanities and Languages” contribute double concerning e-content modules than “Engineering, Technology and Management”, “Physical and Basic Sciences” and “Bio-Medical and Health Sciences”. Additional statistical analysis (Pearson’s Correlation test) shows that a strong positive correlation was observed between the two variables No. of Paper & No. of Uploaded Module (rp =0.683, p= <.001).

description: Double-slits provide incoming photons with a choice. Those that survive the passage have chosen from two possible paths which interfere to distribute them in a wave-like manner. Such wave-particle duality continues to be challenged and investigated in a broad range of disciplines with electrons, neutrons, helium atoms, C60 fullerenes, Bose-Einstein condensates and biological molecules. All variants have hitherto involved material constituents. We present a matterless double-slit scenario in which photons generated from virtual electron-positron pair annihilation in head-on collisions of a probe laser field with two ultra-intense laser beams form a double-slit interference pattern. Such electromagnetic fields are predicted to induce material-like behaviour in the vacuum, supporting elastic scattering between photons. Our double-slit scenario presents on the one hand a realisable method to observe photon-photon scattering, and demonstrates on the other, the possibility of both controlling light with light and non-locally investigating features of the quantum vacuum's structure.

description: This is a study of the number, capacity, and production of cooperative feed manufacturers in the U.S. formula feed industry. Cooperative mills with a capacity of 10,000 tons per year or more increased both the number of mills and total output. Number of establishments and production decreased for smaller mills. Formula feed production rose from 20 million tons in 1975 to 24 million tons in 1984. This production remained centered in the Corn Belt and Lake States regions. However, the Southeast saw the greatest increase in production by cooperatives and also the strongest market share of formula feed by cooperatives. Meal remains the most common feed form produced by cooperatives and dairy the most common livestock consumer group.

description: I study a multi-sender signaling game between an uninformed decision maker and two senders with common private information and conflicting interests. Senders can misreport information at a cost that is tied to the size of the misrepresentation. The main results concern the amount of information that is transmitted in equilibrium and the language used by senders to convey such information. Fully revealing and pure-strategy equilibria exist but are not plausible. I first identify sufficient conditions under which equilibria are essentially unique, robust, and always exist, and then deliver a complete characterization of these equilibria. As an application, I study the informative value of different judicial procedures.

description: We consider finite-dimensional nonlinear systems with linear part described by a parity-time (PT-) symmetric operator. We investigate bifurcations of stationary nonlinear modes from the eigenstates of the linear operator and consider a class of PT-symmetric nonlinearities allowing for existence of the families of nonlinear modes. We pay particular attention to the situations when the underlying linear PT-symmetric operator is characterized by the presence of degenerate eigenvalues or exceptional-point singularity. In each of the cases we construct formal expansions for small-amplitude nonlinear modes. We also report a class of nonlinearities allowing for the system to admit one or several integrals of motion, which turn out to be determined by the pseudo-Hermiticity of the nonlinear operator.

Thermodynamic scaling of dynamics in polymer melts: Predictions from the generalized entropy theory
Creators: name: Xu, Wen-Sheng
name: Freed, Karl F.

Year: 2013
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Many glass-forming fluids exhibit a remarkable thermodynamic scaling in which dynamic properties, such as the viscosity, the relaxation time, and the diffusion constant, can be described under different thermodynamic conditions in terms of a unique scaling function of the ratio rho^gamma/T, where rho is the density, T is the temperature, and gamma is a material dependent constant. Given the successes of the generalized entropy theory in elucidating the influence of molecular details on the universal properties of glass-forming polymers, this theory is extended here to investigate the thermodynamic scaling in polymer melts. The predictions of theory are in accord with the appearance of thermodynamic scaling for pressures not in excess of about 50 MPa. (The failure at higher pressures arises due to inherent limitations of a lattice model.) In line with arguments relating the magnitude of gamma to the steepness of the repulsive part of the intermolecular potential, the abrupt, square-well nature of the lattice model interactions lead, as expected, to much larger values of the scaling exponent. Nevertheless, the theory is employed to study how individual molecular parameters affect the scaling exponent in order to extract a molecular understanding of the information content contained in the exponent. The chain rigidity, cohesive energy, chain length, and the side group length are all found to significantly affect the magnitude of the scaling exponent, and the computed trends agree well with available experiments. The variations of gamma with these molecular parameters are explained by establishing a correlation between the computed molecular dependence of the scaling exponent and the fragility. Thus, the efficiency of packing the polymers is established as the universal physical mechanism determining both the fragility and the scaling exponent gamma.

description: Election data represent a precious source of information to study human behavior at a large scale. In proportional elections with open lists, the number of votes received by a candidate, rescaled by the average performance of all competitors in the same party list, has the same distribution regardless of the country and the year of the election. Here we provide the first thorough assessment of this claim. We analyzed election datasets of 15 countries with proportional systems. We confirm that a class of nations with similar election rules fulfill the universality claim. Discrepancies from this trend in other countries with open-lists elections are always associated with peculiar differences in the election rules, which matter more than differences between countries and historical periods. Our analysis shows that the role of parties in the electoral performance of candidates is crucial: alternative scalings not taking into account party affiliations lead to poor results.

description: Back in the mid eighties, a new branch of investigation which was related to the interaction of eta mesons with nuclei came into existence. It started with the theoretical prediction of possible exotic states of eta mesons and nuclei bound by the strong interaction and later developed into an extensive experimental program to search for such unstable states as well as understand the underlying interaction via eta meson producing reactions. The vast literature of experimental as well as theoretical works which studied various aspects of eta producing reactions such as the $π^+$ $n$ $\to ηp$, $p d \to ^3$He $η$, $p \,^6$Li $\to ^7$Be $η$ and $γ^3$He $\to η$ X, to name a few, had but one objective in mind: to understand the eta - nucleon ($ηN$) and hence the $η$-nucleus interaction which could explain the production data and confirm the existence of some $η$-mesic nuclei. In spite of these efforts, there remain uncertainties in the knowledge of the $ηN$ and hence the $η$-nucleus interaction. The present review is hence an attempt to bind together the findings in these works and draw some global and specific conclusions which can be useful for future explorations.

description: Polo-like kinase 1 (PLK1) is a conserved mitotic serine-threonine protein kinase, functions as a regulatory protein, and is involved in the progression of the mitotic cycle. It plays important roles in the regulation of cell division, maintenance of genome stability, in spindle assembly, mitosis, and DNA-damage response. PLK1 is consist of a N-terminal serine-threonine kinase domain, and a C-terminal Polo-box domain (regulatory site). The expression of PLK1 is controlled by transcription repressor in the G1 stage and transcription activators in the G2 stage of the cell cycle. Overexpression of PLK1 results in undermining of checkpoints causes excessive cellular division resulting in abnormal cell growth, leading to the development of cancer. Blocking the expression of PLK1 by an antibody, RNA interference, or kinase inhibitors, causes a subsequent reduction in the proliferation of tumour cells and induction of apoptosis in tumour cells without affecting the healthy cells, suggesting an attractive target for drug development. In this review, we discuss detailed information on expression, gene and protein structures, role in different diseases, and progress in the design and development of PLK1 inhibitors. We have performed an in-depth analysis of the PLK1 inhibitors and their therapeutic implications with special focus to the cancer therapeutics.

description: We present a new approach for spatiotemporal focusing through complex scattering media by wave front shaping. Using a nonlinear feedback signal to shape the incident pulsed wave front, we show that the limit of a spatiotemporal matched filter can be achieved, i.e., the wave amplitude at the intended time and focus position is maximized for a given input energy. It is exactly what is also achieved with time-reversal. Demonstrated with ultrasound experiments, our method is generally applicable to all types of waves.
Extreme-value statistics of networks with inhibitory and excitatory couplings

description: Inspired by the importance of inhibitory and excitatory couplings in the brain, we analyze the largest eigenvalue statistics of random networks incorporating such features. We find that the largest real part of eigenvalues of a network, which accounts for the stability of an underlying system, decreases linearly as a function of inhibitory connection probability up to a particular threshold value, after which it exhibits rich behaviors with the distribution manifesting generalized extreme value statistics. Fluctuations in the largest eigenvalue remain somewhat robust against an increase in system size but reflect a strong dependence on the number of connections, indicating that systems having more interactions among its constituents are likely to be more unstable.

Passive acoustic monitoring of harbour porpoise behaviour, distribution and density in tidal rapid habitats

description: Toothed whales produce regular echolocation clicks to sense their surroundings and hunt. These clicks can be detected on hydrophones allowing researchers to study and monitor animals, a methodology known as passive acoustic monitoring (PAM). PAM methods can be used to detect behaviours such as foraging, calculate the absolute abundance and determine the 3D positions of soniferous animals. However, this requires robust detection, species classification and localisation algorithms alongside a statistical framework to estimate animal density. Detection, classification and localisation methods were developed to obtain fine scale behavioural information of toothed whales which was then integrated with a distance sampling-based framework to estimate density. These methods were applied to calculate the behaviour, 3D distribution and density of harbour porpoises in a tidal stream habitat. Toothed whales produce clicks in sequences (clicks trains) which can provide information on behavioural state and aid in species identification. A click train detection algorithm was developed to extract these sequences and performance then tested on PAM data from sperm whales, delphinids and harbour porpoise datasets. Localisation in tidal rapids is difficult due to fast moving currents and high densities of toothed whales producing a complex soundscape. A drifting free-hanging vertical hydrophone array with movement sensors, click aliasing and track association algorithms was developed to collect geo-referenced 3D tracks of toothed whales in tidal streams. The full 4π beam profile of a free-swimming captive harbour porpoise was measured. This showed that harbour porpoises have significant acoustic energy at extreme off-axis angles (>30°) which has implications for detectability on PAM devices. Drifting sound recorders and vertical hydrophones arrays were used to survey a tidal rapid site. Detected click trains, dive data and the measured beam profile were used to inform simulations of detection probability of harbour porpoise clicks and calculate animal density and foraging rates.

description: Guanine-rich oligonucleotide (GRO) can be developed as an effective anticancer agent owing to its high selectivity, affinity and antiproliferative activity in cancer cells. In this study, to increase the potency of GRO29A, a 29-mer GRO aptamer against nucleolin, an overexpressed protein in cancer cells, GRO29A was incorporated into three or six pods of polypod-like structured DNA (polypodna), tripodna or hexapodna, respectively. The polypod-like structured GROs, tri-G3, consisting of one tripodna and three GRO29A, or hexa-G1, hexa-G3 or hexa-G6, each of which comprises one hexapodna and one, three or six GRO29A, respectively, were designed. Tri-G3, hexa-G1 and hexa-G3 were prepared in high yield, except for hexa-G6. Polypod-like structured GROs had quadruplex structures under physiological salt conditions, and degraded at a slower rate in buffer containing serum. Cellular interaction experiments using fluorescently labelled DNA samples showed that the uptake of hexa-G3 by nucleolin-positive MCF-7 cells was more than 2-fold higher than GRO29A, and the interaction was increasingly dependent on the number of GRO29A in the structures. Hexa-G3 inhibited the proliferation of MCF-7 cells in more than 40%, but not of CHO cells. These results indicate that polypod-like structured GROs are useful DNA aptamers with high selectivity and cytotoxicity against nucleolin-positive cancer cells.

Here it will be shown how the mignon-mechanism works in detail. In particular the Shubnikov group $A_4 + S (S_4 - A_4)$ will be used to describe the spectrum, and the mignetic ground state is explicitly given.

In the simulations, the tip and surface interact with a conservative nonlinear force, and the parameter space of approach distance and surface stiffness is explored. Approach experiments are carried out on three surfaces with widely varying stiffness. Qualitative similarities between simulations and experiment can be seen, but quantitative comparison is difficult due to the overly idealized tip-surface force model used in the simulation.

description: In situ scanning transmission electron microscopy (STEM) through liquids is a promising approach for exploring biological and materials processes. However, options for in situ chemical identification are limited: X-ray analysis is precluded because the liquid cell holder shadows the detector, and electron energy-loss spectroscopy (EELS) is degraded by multiple scattering events in thick layers. Here, we explore the limits of EELS for studying chemical reactions in their native environments in real time and on the nanometer scale. The determination of the local electron density, optical gap and thickness of the liquid layer by valence EELS is demonstrated. By comparing theoretical and experimental plasmon energies, we find that liquids appear to follow the free-electron model that has been previously established for solids. Signals at energies below the optical gap and plasmon energy of the liquid provide a high signal-to-background ratio regime as demonstrated for LiFePO4 in aqueous solution. The potential for using valence EELS to understand in situ STEM reactions is demonstrated for beam-induced deposition of metallic copper: as copper clusters grow, EELS develops low-loss peaks corresponding to metallic copper. From these techniques, in situ imaging and valence EELS offer insight into the local electronic structure of nanoparticles and chemical reactions.

description: Auf den Punkt ...
Eine in einem politikwissenschaftlichen Seminar durchgeführte Befragung von angehenden Abiturient/inn/en zeigt, dass viele kurz vor dem Abitur noch keine klare Entscheidung über ihren weiteren Bildungs- und Berufsweg getroffen haben und der Orientierungsbedarf groß ist.
Bei den Zukunftsplanungen steht der Wunsch nach einem Universitätsstudium ganz weit oben, insbesondere dann, wenn mindestens ein Elternteil selbst über einen Universitätsabschluss verfügt.
Fast die Hälfte der Schüler/innen könnte sich kurz vor dem Abitur vorstellen, im Anschluss eine Berufsausbildung aufzunehmen. Konkrete Schritte in diese Richtung hat jedoch zu diesem Zeitpunkt nur eine Minderheit unternommen.
Ein vielfältiges, durch die Schule initiiertes Angebot der Berufs- und Studienwahlorientierung kann dazu beitragen, dass die Abiturient/inn/en sich auf ihren weiteren Weg besser vorbereitet fühlen.
Die Eltern spielen eine wichtige Rolle; ihre Beratung und Unterstützung wird von den Abiturent/inn/en mehrheitlich positiv bewertet.

description: Interference is a major performance bottleneck in Heterogeneous Network (HetNet) due to its multi-tier topological structure. We propose almost blank resource block (ABRB) for interference control in HetNet. When an ABRB is scheduled in a macro BS, a resource block (RB) with blank payload is transmitted and this eliminates the interference from this macro BS to the pico BSs. We study a two timescale hierarchical radio resource management (RRM) scheme for HetNet with dynamic ABRB control. The long term controls, such as dynamic ABRB, are adaptive to the large scale fading at a RRM server for co-Tier and cross-Tier interference control. The short term control (user scheduling) is adaptive to the local channel state information within each BS to exploit the multi-user diversity. The two timescale optimization problem is challenging due to the exponentially large solution space. We exploit the sparsity in the interference graph of the HetNet topology and derive structural properties for the optimal ABRB control. Based on that, we propose a two timescale alternative optimization solution for the user scheduling and ABRB control. The solution has low complexity and is asymptotically optimal at high SNR. Simulations show that the proposed solution has significant gain over various baselines.

description: I analyze the correlation function of currents generated by the periodically driven quantum capacitor emitting single electrons and holes into the chiral waveguide. I compare adiabatic and non-adiabatic, transient working regimes of a single-electron emitter and find the striking difference between the correlation functions in two regimes. Quite generally for the system driven with frequency $Ω$ the correlation function depends on two frequencies, $ω$ and $\ell Ω- ω$, where $\ell$ is an integer. For the emitter driven non-adiabatically the correlation functions for different $\ell$ are similar and almost symmetric in $ω$. While in the case of adiabatic drive the correlation functions for $\ell \ne 0$ are highly asymmetric in $ω$ and exceed significantly the one corresponding to $\ell = 0$. Under optimal operating conditions the correlation function for odd $\ell$ is zero.

description: This study utilizes the TIMSS 2019 dataset to scrutinize the school engagement of 8th-grade students within the Turkish education system. Employing the Random Forest method, a data mining technique, we investigate factors in science and mathematics domains that are theorized to influence school engagement. The research delves into psychological elements, including lesson preferences, confidence in science, self-assurance, absenteeism, and the impact of teachers' instructional methods on school engagement, with a specific focus on student bullying. The sample comprises 3872 students in the science dataset and 3802 students in the mathematics dataset, resulting from data deletion and assignment processes from the original 4077 participants. Analysis utilized the open-source Python infrastructure, with the Orange 3.32 data mining program facilitating model setup. Evaluation metrics such as MSE, RMSE, MAE, and R2 values were employed to assess model performance. Results reveal commendable model performance, with values approximating zero in both science (MSE: 2.775, RMSE: 1.666, MAE: 1.267) and mathematics (MSE: 2.240, RMSE: 1.497, MAE: 1.131) domains. Variables accounted for 69.6% of school engagement in science and 75.7% in mathematics. The order of importance of variables exhibited substantial similarities in both areas, with student bullying identified as the most crucial factor. Our findings underscore the significance of addressing student bullying to enhance school engagement, emphasizing the psychological needs and attachment of middle school students. Future research endeavors should employ qualitative data collection methods, considering perspectives from students, peers, teachers, and parents. We recommend that education policies, particularly those crafted by the Turkish Ministry of National Education, prioritize sustained efforts to reduce and prevent student bullying in schools. School administrations, supported by counselors, should focus on diagnosing and mitigating bullying-related issues within and outside the school environment

description: Recently, Lobb and Nijhoff initiated the study of variational (Lagrangian) structure of discrete integrable systems from the perspective of multi-dimensional consistency. In the present work, we follow this line of research and develop a Lagrangian theory of integrable one-dimensional systems. We give a complete solution of the following problem: one looks for a function of several variables (interpreted as multi-time) which delivers critical points to the action functionals obtained by integrating a Lagrangian 1-form along any smooth curve in the multi-time. The Lagrangian 1-form is supposed to depend on the first jet of the sought-after function. We derive the corresponding multi-time Euler-Lagrange equations and show that, under the multi-time Legendre transform, they are equivalent to a system of commuting Hamiltonian flows. Involutivity of the Hamilton functions turns out to be equivalent to closeness of the Lagrangian 1-form on solutions of the multi-time Euler-Lagrange equations. In the discrete time context, the analogous extremal property turns out to be characteristic for systems of commuting symplectic maps. For one-parameter families of commuting symplectic maps (Bäcklund transformations), we show that their spectrality property, introduced by Kuznetsov and Sklyanin, is equivalent to the property of the Lagrangian 1-form to be closed on solutions of the multi-time Euler-Lagrange equations, and propose a procedure of constructing Lax representations starting from the maps themselves.

stellar coronal mass ejections

description: A lot has been done on an observational basis in the past with respect to stellar coronal mass ejections. Using the method of Doppler-shifted emission/absorption, still, only fast events can be unambiguously identified with erupting filaments/prominences. These often form the cores of CMEs on the Sun. From dM stars we know that there are numerous observations of Doppler-shifted emission events with projected velocities of 100-300km/s.
 Constraints are needed to better interpret those signatures which are potential CME candidates. We have chosen cloud modeling to constrain what might produce such signatures. We focus on one known event from the literature, found on the fast rotating dMe star V374 Peg, and find that both a filament and a prominence scenario reproduces the peak flux of the Doppler-shifted emission signatures, contrary to the solar case where filaments produce an absorption signature in the Balmer lines. The deduced parameters from modeling show values in the upper range of solar prominence parameters, except engfor temperature and area, which are larger. A prominence/filament eruption scenario is therefore very likely for the event found on V374 Peg.

description: Multi-band Hubble Space Telescope photometry reveals that the main sequence, sub-giant, and the red giant branch of the globular cluster NGC6752 splits into three main components in close analogy with the three distinct segments along its horizontal branch stars. These triple sequences are consistent with three stellar groups: a stellar population with a chemical composition similar to field halo stars (population a), a population (c) with enhanced sodium and nitrogen, depleted carbon and oxygen and enhanced helium abundance (Delta Y ~0.03), and a population (b) with an intermediate (between population a and c) chemical composition and slightly helium enhanced (Delta Y ~0.01). These components contain ~25% (population a), ~45% (population b), and ~30% (population c) of the stars. No radial gradient for the relative numbers of the three populations has been identified out to about 2.5 half mass radii.

description: We show that in supersymmetric axion models the axion supermultiplet obtains a sizable F-term due to a non-supersymmetric dynamics and it generally gives the gaugino masses comparable to the anomaly mediation contribution. Thus the gaugino mass relation predicted by the anomaly mediation effect can be significantly modified in the presence of axion to solve the strong CP problem.
