Social media impact
information dissemination]

description: The rapid proliferation and widespread adoption of Web 2.0 websites and Internet/desktop applications have ushered in an era where students are empowered with an unprecedented wealth of information and a vast network of knowledge resources, all accessible with a simple click. This technological evolution has transformed the conventional methods of acquiring knowledge, eliminating the need for traditional approaches such as perusing books or visiting libraries. For the contemporary internet user or student, accessing the definition of a new term or solving a complex mathematical equation is just a click away. The scope of writing an essay on a favorite personality has transcended the confines of a limited set of 10 specific names, with platforms like Wikipedia providing expansive information.

The virtual realm has revolutionized exploration and learning, allowing individuals to traverse countries or tourist destinations virtually before physically visiting them. Platforms like YouTube have become instrumental in democratizing the acquisition of various arts and techniques through instructional videos. Social media has flourished, offering countless avenues to make friends, join groups, and engage in discussions on diverse topics through forums or dedicated social media groups. Additionally, the landscape of news dissemination has undergone a radical shift, breaking free from the constraints of print media and permeating various online platforms, from social media to dedicated websites and discussion forums.

This transformative shift in the dynamics of information access has not only altered the learning landscape but has also redefined the way individuals interact, share, and disseminate information. This paper explores the profound impact of Web 2.0 technologies on education, information dissemination, and social interaction. By examining the changes brought about by these technologies, we aim to understand the implications for students, educators, and society at large. The investigation encompasses diverse facets, including the evolving nature of research methodologies, the democratization of knowledge, and the changing dynamics of social connectivity

description: Starting from Nahm's equations, we explore BPS magnetic monopoles in the Yang-Mills Higgs theory of gauge group $Sp(4)$ which is broken to $SU(2)\times U(1)$. A family of BPS field configurations with purely Abelian magnetic charge describe two identical massive monopoles and one massless monopole. We construct the field configurations with axial symmetry by employing the ADHMN construction, and find the explicit expression of the metrics for the 12-dimensional moduli space of Nahm data and its submanifolds.

description: Campylobacter jejuni causes a leading human gastrointestinal infection which is associated with foodborne diarrhea, stomach cramping, and fever. In the recent years, numerous multidrug-resistant strains of C. jejuni has evolved and is considered in the priority pathogens category. Therefore, an increasing demand exists to develop an effective vaccine against Campylobacteriosis. The T cell and B cell epitopes from the FlaC protein were predicted using comprehensive immunoinformatics tools. The predicted epitopes were chosen based on their antigenicity, allergenicity, and toxicity profiles. Using the bioinformatics approach various physicochemical properties of the constructed vaccine were determined. The molecular docking analysis of the vaccine with the TLRs demonstrated that TLR5 has a higher binding affinity of −1159.0 kcal/mol. Molecular dynamics simulation has confirmed the stable association of the vaccine with TLR5. The immune response of the constructed vaccine was validated using immunostimulation. Based on this study, we recommend the formulation of a multi-epitope vaccine as a promising agent to effectively combat the dreadful campylobacteriosis infection.

description: We have carried out numerical hydrodynamic simulations of radio jets from active galactic nuclei using the PLUTO simulation code, with the aim of investigating the effect of different environments and intermittency of energy injection on the resulting dynamics and observable properties of the jet-inflated lobes. Initially conical jets are simulated in poor group and cluster environments. We show that the environment into which a radio jet is propagating plays a large role in the resulting morphology, dynamics and observable properties of the radio source. The same jet collimates much later in a poor group compared to a cluster, which leads to pronounced differences in radio morphology. The intermittency of the jet also affects the observable properties of the radio source, and multiple hotspots are present for multiple outburst jets in the cluster environment. We quantify the detectability of active and quiescent phases, and find this to be strongly environment-dependent. We conclude that the dynamics and observational properties of jets depend strongly on the details of energy injection and environment.

Duality, Phases, Spinors and Monopoles in SO(N) and Spin(N) Gauge Theories
Creators: name: Strassler, Matthew J.

Year: 1997
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Four-dimensional N=1 supersymmetric Spin(N) gauge theories with matter in the vector and spinor representations are considered. Dual descriptions are known for some of these theories. It is noted that when masses are given to all fields in the spinor representation, the dual gauge group G breaks to a group H such that π_2(G/H)=Z_2. The quantum numbers of the associated Z_2 monopole and those of the massive spinors are shown to agree, suggesting that the monopole is the image of the massive spinors under duality. It follows that electric sources in the spinor representation, needed as test charges to determine the phase of an SO(N) gauge theory, can be introduced as Z_2-valued magnetic sources in the dual nonabelian gauge theory. This fact is used to study the phases of SO(N) gauge theories with matter in the vector representation.

description: This paper proposes a method for compensation of dead-time effects for a fivephase inverter. In the proposed method an additional control subsystem was added to the field-oriented control (FOC) scheme in the coordinate system mapped to the third harmonic. The additional control loop operates in the fixed, orthogonal reference frame ( α - β coordinates) without the need for additional Park transformations. The purpose of this method is to minimize the dead-time effects by third harmonic injection in two modes of operation of the FOC control system: with sinusoidal supply and with trapezoidal supply. The effectiveness of the proposed control method was verified experimentally on a laboratory setup with a prototype five-phase interior permanent magnet synchronous machine (IPMSM). All experimental results were presented and discussed in the following paper.

description: Deep Neural Networks (DNNs) are becoming increasingly important as scientific tools, as they excel in various scientific applications beyond what was considered possible. Yet from a certain vantage point, they are nothing but parametrized functions of some data vector , and their ‘learning’ is nothing but an iterative, algorithmic fitting of the parameters to data. Hence, what could be special about them as a scientific tool or model? I will here suggest an integrated perspective that mediates between extremes, by arguing that what makes DNNs in science special is their ability to develop functional concept proxies (FCPs): Substructures that occasionally provide them with abilities that correspond to those facilitated by concepts in human reasoning. Furthermore, I will argue that this introduces a problem that has so far barely been recognized by practitioners and philosophers alike: That DNNs may succeed on some vast and unwieldy data sets because they develop FCPs for features that are not transparent to human researchers. The resulting breach between scientific success and human understanding I call the ‘Actually Smart Hans Problem’.

title: Faith, frolics, and femininity: re-evaluating Irene Dunne's Hollywood stardom
Creators: name: McKay, Ciara Patricia
Publisher: name: The University of Edinburgh

Subjects: subject: Irene Dunne
subject: Hollywood
subject: film studies
subject: feminist ideals
subject: misogyny

description: Irene Dunne (1898-1990) remained a top tier Hollywood star for over twenty years due to her ability to transform her stardom every few years without changing the core values of her persona, refreshing her career without neglecting the traits of independence, professionalism, and ambition which were key to her popularity. This thesis focuses on the moments when Dunne transformed her image arguing that she provided a rich, but currently underappreciated, example of feminine autonomy for mid-century audiences and beyond. I draw on a wide range of primary sources – including contemporary newspapers and magazines and Dunne’s personal archives – to argue that she has been undervalued within the film studies canon. Challenging views of her as one of Hollywood’s more conservative and ‘ladylike’ stars, I combine close film analysis with archival sources to highlight her promotion throughout her film career (1930-1952) of modern, feminist lifestyle choices for women which involved work outside the home, companionate marriage, and financial independence. I explore Dunne’s engagement with taboos such as divorce, adultery, and abortion in her early, pre-Code career. These subversive performances contradict critical views of her as a ‘perfect lady’ prevalent since the end of her film career in 1952. The thesis then considers how her unruly screwball comedy performances of drunkenness critiqued contemporary suppression of women’s visibility in public life. In the 1940s Dunne moved into playing mother roles, and I link these performances to her personal Catholic faith and devotion to the Virgin Mary. Dunne’s mid-1940s characters clearly called upon long-enduring traditions which placed Mary as an emblem of strength and perseverance for Catholic women. Finally, I identify Dunne’s centrality to changing contemporary attitudes on female middle age, emphasising her enduring appeal as the star of romantic dramas well into her late forties and early fifties as a corrective to classical Hollywood’s association with youthful starlets.

description: The phase diagram of the Blume--Capel model on a semi--infinite simple cubic lattice with a (100) free surface is studied in the pair approximation of the cluster variation method. Six main topologies are found, of which two are new, due to the occurrence of a first order surface transition in the phase with ordered bulk, separating two phases with large and small surface order parameters. The latter is a new phase and is studied in some detail, giving the behaviour of the order parameter profiles in two typical cases. A comparison is made with the results of a low temperature expansion, where these are available, showing a great increase in accuracy with respect to the mean field approximation.

Measurement of the Probability of Gluon Splitting into Charmed Quarks in Hadronic Z Decays
Creators: name: L3 Collaboration
Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: We have measured the probability, n(g->cc~), of a gluon splitting into a charm-quark pair using 1.7 million hadronic Z decays collected by the L3 detector. Two independent methods have been applied to events with a three-jet topology. One method relies on tagging charmed hadrons by identifying a lepton in the lowest energy jet. The other method uses a neural network based on global event shape parameters. Combining both methods, we measure n(g->cc~)= [2.45 +/- 0.29 +/- 0.53]%.

description: Some indications for tension have long been identified between cosmological constraints obtained from galaxy clusters and primary CMB measurements. Typically, assuming the matter density and fluctuations, as parameterized with Omega_m and sigma_8, estimated from CMB measurements, many more clusters are expected than those actually observed. One possible explanation could be that certain types of galaxy groups or clusters were missed in samples constructed in previous surveys, resulting in a higher incompleteness than estimated. We aim to determine if a hypothetical class of very extended, low surface brightness, galaxy groups or clusters have been missed in previous X-ray cluster surveys based on the ROSAT All-Sky Survey (RASS). We applied a dedicated source detection algorithm sensitive also to more unusual group or cluster surface brightness distributions. We found many known but also a number of new group candidates, which are not included in any previous X-ray / SZ cluster catalogs. In this paper, we present a pilot sample of 13 very extended groups discovered in the RASS at positions where no X-ray source has been detected previously and with clear optical counterparts. The X-ray fluxes of at least 5 of these are above the nominal flux-limits of previous RASS cluster catalogs. They have low mass ($10^{13} - 10^{14} M_{\odot}$; i.e., galaxy groups), are at low redshift (z<0.08), and exhibit flatter surface brightness distributions than usual. We demonstrate that galaxy groups were missed in previous RASS surveys, possibly due to the flat surface brightness distributions of this potential new population. Analysis of the full sample will show if this might have a significant effect on previous cosmological parameter constraints based on RASS cluster surveys.

description: The radiative spin-flip transition rates of heavy quarkonium states depend sensitively on the matrix elements of the effective confining interaction through the associated two-quark exchange current operator. The Hamiltonian model based on a scalar linear confining interaction with a single gluon exchange hyperfine term is shown to provide an adequate description of the $J/ψ\to η_cγ$ and $ψ(2S)\to η_cγ$ decay widths once the relativistic single quark magnetic moment operator is treated without approximation and the exchange current is taken into account. Predictions are given for the radiative spin-flip decay widths of the 1S,2S and 3S states of the $c\bar c$, $b\bar b$ and $B_c^+$ systems. In the B_c^+ system the gluon exchange current also contributes to the spin-flip transition rates.

We show that these CI Jordan type partitions are those satisfying specific numerical conditions; also, given the Hilbert function $H(A)$, they are completely determined by which higher Hessians of $A$ vanish at the point corresponding to the linear form. We also show new combinatorial results about such partitions, and in particular we give ways to construct them from a branch label or hook code, showing how branches are attached to a fundamental triangle to form the Ferrers graph.

Measurement of Longitudinal Spin Transfer to Lambda Hyperons in Deep-Inelastic Lepton Scattering

Year: 1999
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: Spin transfer in deep-inelastic Lambda electroproduction has been studied with the HERMES detector using the 27.6 GeV polarized positron beam in the HERA storage ring. For an average fractional energy transfer = 0.45, the longitudinal spin transfer from the virtual photon to the Lambda has been extracted. The spin transfer along the Lambda momentum direction is found to be 0.11 +/- 0.17 (stat) +/- 0.03 (sys); similar values are found for other possible choices for the longitudinal spin direction of the Lambda. This result is the most precise value obtained to date from deep-inelastic scattering with charged lepton beams, and is sensitive to polarized up quark fragmentation to hyperon states. The experimental result is found to be in general agreement with various models of the Lambda spin content, and is consistent with the assumption of helicity conservation in the fragmentation process.

description: Extending and growing a more diverse set of grain legumes is an opportunity to reduce the dependence on imported proteins as well as for diversifying agro-ecosystems. Lupine and soybean could be innovative solutions while offering a sustainable agronomic and economic alternative to organic farmers. Both species feature interesting characteristics for fodder production and for human consumption: while soybean is superior in grain protein content and oil, lupine is interesting for its high protein amount and especially its cysteine and methionine contents, which are scarce in locally produced grain legumes. In recent years, attempts have been made to study the feasibility of soybean cultivation in Sweden, showing that early maturing soybean cultivars could cope with the growing conditions even up to 59° N with up to 2.4 t ha-1 grain yield and a typical protein content of 39-41%. Further, it has been demonstrated that narrow-leafed lupine can grow at latitudes of 60° N. Despite these advancements, there is a lack of scientific evidence for cultivar selection, crop management and productivity to support the development and realization of commercial soybean and lupine production in Sweden. Moreover, the cultivation of these crops was never done in contrasting Scandinavian pedoclimatic zones, in which differences in growing season- and day length are major constraints.

description: The rapid advancement of technology has transformed the global landscape, turning the world into a tightly-knit global village. This transformative shift is particularly evident among higher education students, who find themselves increasingly immersed in a myriad of social media platforms. From cutting-edge iPhones to the latest online applications, students in universities are actively engaged in a diverse array of social media, ranging from popular blogs and social networking sites like Facebook, Snapchat, Instagram, Twitter, Skype, Google +, LinkedIn, WhatsApp, to content-sharing platforms such as YouTube.

Social media, as defined by Rouse (2013), encompasses online communication channels dedicated to community-based interaction, content-sharing, and collaboration. These platforms, including websites and applications facilitating fora, microblogging, social networking, and social bookmarking, serve as web-based tools that enable individuals to connect, share, and consume information. For university students, the use of social media extends beyond mere entertainment, with these platforms serving as invaluable learning tools, as highlighted by Al-Tarawineh (2014).

This paper explores the multifaceted role of social media in the lives of university students, addressing both positive and negative aspects of their engagement. On one hand, social media serves as a medium for social interaction, information retrieval, and leisure activities. On the other hand, it has found a place in the educational landscape, being utilized for teaching and learning purposes. However, amidst these positive applications, there is a growing concern about the negative consequences of excessive social media use. Students, in their quest for connection and information, also grapple with negative addictions such as involvement in cyber fraud, crime, bullying, harassment, and the consumption of explicit content (Graham & Kingsley, 2005).

Through an exploration of these various dimensions, this paper aims to provide insights into the evolving relationship between university students and social media. It delves into the dynamics of their engagement, examining the impact on both personal and academic spheres. The study seeks to contribute to the ongoing discourse on the integration of social media in higher education, shedding light on the challenges and opportunities it presents.Social Mediaz
Modelling background charge rearrangements near single-electron transistors as a Poisson process

description: Background charge rearrangements in metallic single-electron transistors are modelled in two-level tunnelling systems as a Poisson process with a scale parameter as only variable. The model explains the recent observation of asymmetric Coulomb blockade peak spacing distributions in metallic single-electron transistors. From the scale parameter we estimate the average size of the tunnelling systems, their density of states, and the height of their energy barrier. We conclude that the observed background charge rearrangements predominantly take place in the substrate of the single-electron transistor.

description: In the present paper we study the Faddeev-Popov path integral quantization of electrodynamics in an inhomogenious dielectric medium. We quantize all polarizations of the photons and introduce the corresponding ghost fields. Using the heat kernel technique, we express the heat kernel coefficients in terms of the dielectricity $ε(x)$ and calculate the ultra violet divergent terms in the effective action. No cancellation between ghosts and "non-physical" degrees of freedom of the photon is observed.

description: We demonstrate the local control of up to eight two-level systems interacting strongly with a microwave cavity. Following calibration, the frequency of each individual two-level system (qubit) is tunable without influencing the others. Bringing the qubits one by one on resonance with the cavity, we observe the collective coupling strength of the qubit ensemble. The splitting scales up with the square root of the number of the qubits, which is the hallmark of the Tavis-Cummings model. The local control circuitry causes a bypass shunting the resonator, and a Fano interference in the microwave readout, whose contribution can be calibrated away to recover the pure cavity spectrum. The simulator's attainable size of dressed states with up to five qubits is limited by reduced signal visibility, and -- if uncalibrated -- by off-resonance shifts of sub-components. Our work demonstrates control and readout of quantum coherent mesoscopic multi-qubit system of intermediate scale under conditions of noise.

description: The infinite-$U$ single impurity Anderson model for rare earth alloys is examined with a new set of self-consistent coupled integral equations, which can be embedded in the large $N$ expansion scheme ($N$ is the local spin degeneracy). The finite temperature impurity density of states (DOS) and the spin-fluctuation spectra are calculated exactly up to the order $O(1/N^2)$. The presented conserving approximation goes well beyond the $1/N$-approximation ({\em NCA}) and maintains local Fermi-liquid properties down to very low temperatures. The position of the low lying Abrikosov-Suhl resonance (ASR) in the impurity DOS is in accordance with Friedel's sum rule. For $N=2$ its shift toward the chemical potential, compared to the {\em NCA}, can be traced back to the influence of the vertex corrections. The width and height of the ASR is governed by the universal low temperature energy scale $T_K$. Temperature and degeneracy $N$-dependence of the static magnetic susceptibility is found in excellent agreement with the Bethe-Ansatz results. Threshold exponents of the local propagators are discussed. Resonant level regime ($N=1$) and intermediate valence regime ($|ε_f|

description: In this study, we examine the mechanism of nanopore-based DNA sequencing using a voltage bias across a graphene nanoribbon. Using density functional theory and a non-equilibrium Green's function approach, we determine the transmission spectra and current profile for adenine, guanine, cytosine, thymine, and uracil as a function of bias voltage in an energy minimized configuration. Utilizing the transmission current, we provide a general methodology for the development of a three nanopore graphene-based device that can be used to distinguish between the various nucleobases for DNA/RNA sequencing. From our analysis, we deduce that it is possible to use different transverse currents across a multi-nanopore device to differentiate between nucleobases using various voltages of 0.5, 1.3, and 1.6 V. Overall, our goal is to improve nanopore design to further DNA/RNA nucleobase sequencing and biomolecule identification techniques.

Exclusive production of vector mesons $ρ, ρ'$ and $ρ''$ by real and virtual photons

description: We present a non-perturbative QCD calculation of high-energy diffractive photo- and leptoproduction of vector mesons $ρ$, $ρ'$ and $ρ''$ on a nucleon. The initial photon splits up in a $q\bar{q}$-dipole and transforms into a vector meson by scattering on the quark-diquark nucleon. The dipole-dipole scattering amplitude is provided by the non-perturbative model of the stochastic QCD vacuum, the wave functions result from considerations on the light-cone. We assume the physical $ρ'$- and $ρ''$-states to be mixed states of an active 2S-excitation and a rest whose coupling to the photon is suppressed. We obtain good agreement with the experimental data and get an understanding of the markedly different spectrum in the $π^+π^-$-invariant mass for photoproduction and $e^+e^-$-annihilation.

description: We consider the Dirac equation in cylindrically symmetric magnetic fields and find its normal modes as eigenfunctions of a complete set of commuting operators. This set consists of the Dirac operator itself, the $z$-components of the linear and the total angular momenta, and of one of the possible spin polarization operators. The spin structure of the solution is completely fixed independently of the radial distribution of the magnetic field which influences only the radial modes. We solve explicitly the radial equations for the uniform magnetic field inside a solenoid of a finite radius and consider in detail the scattering of scalar and Dirac particles in this field. For particles with low energy the scattering cross section coincides with the Aharonov-Bohm scattering cross section. We work out the first order corrections to this result caused by the fact that the solenoid radius is finite. At high energies we obtain the classical result for the scattering cross section.

description: We investigated the pinning of flux lines in a superconducting film by a regular array of magnetic antidots. The sample consists of a Co/Pt multilayer with perpendicular magnetic anisotropy in which a regular pattern of submicron holes is introduced and which is covered by a type-II superconducting Pb film. The resulting ferromagnetic/superconducting heterostructure shows a pronounced asymmetric magnetization curve with respect to the field polarity. This asymmetry clearly demonstrates that the magnetic contribution dominates the pinning potential imposed by the magnetic antidots on the superconducting film.

description: A non-modal linear stability analysis (NMA) of the miscible viscous fingering in a porous medium is studied for a toy model of non-monotonic viscosity variation. The onset of instability and its physical mechanism are captured in terms of the singular values of the propagator matrix corresponding to the non-autonomous linear equations. We discuss two types of non-monotonic viscosity profiles, namely, with unfavorable (when a less viscous fluid displaces a high viscous fluid) and with favorable (when a more viscous fluid displaces a less viscous fluid) end-point viscosities. A linear stability analysis yields instabilities for such viscosity variations. In addition, we also show that to understand the spatiotemporal evolution of the perturbations it is necessary to analyse the viscosity gradient with respect to the concentration and the location of the maximum concentration $c_m$. For the favorable end-point viscosities, a weak transient instability is observed when the viscosity maximum moves close to the pure invading or defending fluid. This instability is attributed to an interplay between the sharp viscosity gradient and the favorable end-point viscosity contrast. We demonstrate the dissimilarity between the quasi-steady-state approach and NMA in finding the correct perturbation structure and the onset, for both the favorable and unfavorable viscosity profiles. The correctness of the linear perturbation structure obtained from the non-modal stability analysis is validated through nonlinear simulations. We have found that the nonlinear simulations and NMA results are in good agreement. In summary, a non-monotonic variation of the viscosity of a miscible fluid pair is seen to have a larger influence on the onset of fingering instabilities, than the corresponding Arrhenius type relationship.

Spin-Phonon Coupling in the Single-Layer Extended t-J Model

description: We consider the implications of spin-phonon coupling within the slave-boson, mean-field treatment of the extended t-J model of a high-temperature superconductor. In bilayer cuprates such as YBaCuO, where the $CuO_2$ plane is buckled, this interaction is linear in $O$ displacement along the c-axis, and the coupling constant is found to be large. The formation of a spin singlet causes additional contributions to the phonon self-energy, and we calculate from these the superconductive phonon anomalies. The magnitude and sign of the frequency shift and linewidth broadening for various mode symmetries correspond well with Raman and infra-red light scattering experiments, and with neutron scattering studies. In the t-J model, spin singlet formation and superconductivity do not coincide in the low-doping regime, giving rise to spin-gap features and a variety of temperature scales in the spin response observed by NMR and neutron investigations. Phonon anomalies in underdoped YBaCuO compounds indeed show evidence of spin-gap phenomena with the same characteristic temperature, suggesting that the theory may offer the possibility of a unified understanding of the anomalies in magnetic and lattice properties. While the origin of the superconducting interaction is electronic, this spin-phonon coupling affords the possibility of a small isotope effect, and our estimate is in good agreement with recent site-selective $O$-substitution experiments.
