description: We investigate the ground and low excited states of a rotating, weakly interacting Bose-Einstein condensed gas in a harmonic trap for a given angular momentum. Analytical results in various limits, as well as numerical results are presented, and these are compared with those of previous studies. Within the mean-field approximation and for repulsive interaction between the atoms, we find that for very low values of the total angular momentum per particle, $L/N \to 0$, where $L \hbar$ is the angular momentum and $N$ is the total number of particles, the angular momentum is carried by quadrupolar ($|m| = 2$) surface modes. For $L/N =1$ a vortex-like state is formed and all the atoms occupy the $m=1$ state. For small negative values of $L/N-1$ the states with $m=0$ and $m=2$ become populated, and for small positive values of $L/N-1$ atoms in the states with $m=5$ and $m=6$ carry the additional angular momentum. In the whole region $0 \le L/N \le 1$ we have strong analytic and numerical evidence that the interaction energy drops linearly as a function of $L/N$. We have also found that an array of singly quantized vortices is formed as $L/N$ increases. Finally we have gone beyond the mean-field approximation and have calculated the energy of the lowest state up to order $N$ for small negative values of $L/N-1$, as well as the energy of the low-lying excited states.

description: Cloud computing is now a day’s become most attracted phenomena to use for a large-scale organization or for individual who need various network services with least cost. Normally, individual’s information is stored on public Cloud which is available to everyone for access. This fundamental raise some issue opposite to flexible services provided by Cloud providers, like Confidentiality, Integrity, Availability, Authorization and many more. To protect the data, lots ofoptions available now a days and most preferable way is to use encryption. Encryption only cannot provide enough protection while considering user’s sensitive information, as well as it consumes more time to process encryption anddecryption. To remove the burden of Cloud server, as well as to keep adequate security to user’s information in Cloud environment, in this paper, we propose a methodology for combining both techniques, viz. obfuscation and encryption. The user data may be encrypted if it requires security for its files or document, and the DaaS service of Cloud must be secured using obfuscation techniques. Using this two-way approach, we can say that the proposed scheme offers enough security towards anonymous access and preserve privacy even of the information available on Cloud Servers. We also aim to provide proper integrity checking mechanism, better access control mechanism which lessens the burden of Client as well as service provider.

description: On the basis of the Chalker-Coddington network model, a numerical and analytical study is made of the statistics of point-contact conductances for systems in the integer quantum Hall regime. In the Hall plateau region the point-contact conductances reflect strong localization of the electrons, while near the plateau transition they exhibit strong mesoscopic fluctuations. By mapping the network model on a supersymmetric vertex model with GL(2|2) symmetry, and postulating a two-point correlator in keeping with the rules of conformal field theory, we derive an explicit expression for the distribution of conductances at criticality. There is only one free parameter, the power law exponent of the typical conductance. Its value is computed numerically to be X_t = 0.640 +/- 0.009. The predicted conductance distribution agrees well with the numerical data. For large distances between the two contacts, the distribution can be described by a multifractal spectrum solely determined by X_t. Our results demonstrate that multifractality can show up in appropriate transport experiments.

description: Stock market direction prediction has always been a subject of interest for most market participants. It was observedin most of the literature, related to stock price prediction, they found difficult to compare and validate the performance of their price prediction models or methodology. To overcome this problem here we proposed a simplified generalized technique called Success Prediction Ratio (SPR) to compare and validate the performance of the stock price prediction model. In this study, we developed price prediction model using artificial neural network following technical analysis approach. Ten well known and reputed stock of National Stock Exchange has selected for analyzed the prediction performance of the model. At the last, wevalidate the performance of the model using Success Prediction Ratio. The study results show that proposed model outperforms in terms of percentage prediction and profitability.

description: Simulation is very easy and important way to analyse anyengineering concept or prototype model before converting itinto operational mode. Especially, simulation is very vital inthe designing of electronic circuits because it gives costeffective result in making of printed circuit board. There aremany simulation software available in the market and eachone has its own merits and demerits. Researchers normallyprefer to use appropriate simulation software forimplementing their research topic and analysing in all aspectsand thus better conclusion can be made very easy and quickly. MATLAB software is most popular simulation software in educational institutions and even for research laboratories. One of such research topics simulation in MATLAB software has been explained in this paper. IEEE Wireless Local Area Network (WLAN) 802.11ac based on Orthogonal Frequency Division Multiplexing (OFDM) technology has been simulated and tested for the purpose of studying synchronization issue in OFDM receiver. Paper focuses on basic principle of OFDM technology and its use in IEEE 802.11ac WLAN standard. It also describes IEEE 802.11ac WLAN simulation results in MATLAB software.

description: In this paper we propose that flux cancellation on small granular scales ($\lesssim 1000$ km) ubiquitously drives reconnection at a multitude of sites in the low solar atmosphere, contributing to chromospheric/coronal heating and the generation of the solar wind. We analyse the energy conversion in these small-scale flux cancellation events using both analytical models and three-dimensional, resistive magnetohydrodynamic (MHD) simulations. The analytical models -- in combination with the latest estimates of flux cancellation rates -- allow us to estimate the energy release rates due to cancellation events, which are found to be of the order $10^6-10^7$ erg cm$^{-2}$sec$^{-1}$, sufficient to heat the chromosphere and corona of the Quiet Sun and active regions, and to power the solar wind. The MHD simulations confirm the conversion of energy in reconnecting current sheets, in a geometry representing a small-scale bipole being advected towards an intergranular lane. A ribbon-like jet of heated plasma is accelerated upwards, that could also escape the Sun as the solar wind in an open-field configuration. We conclude that through two phases of atmospheric energy release -- pre-cancellation and cancellation -- the cancellation of photospheric magnetic flux fragments and the associated magnetic reconnection may provide a substantial energy and mass flux contribution to coronal heating and solar wind generation.

Furthermore, we show that this soliton can be regarded as an exact soliton in the full string field theory. The world-volume theory of the BPS Dp-brane constructed in this way becomes usual gauge theory on commutative R^{p+1}, instead of non-commutative plane. We also construct a D$p$-brane from non-BPS D(p-n)-branes by the ABS like configuration. We confirm that the Dp-brane has correct RR charges and the tension.

description: We consider a weakly-interacting, harmonically-trapped Bose-Einstein condensed gas under rotation and investigate the connection between the energies obtained from mean-field calculations and from exact diagonalizations in a subspace of degenerate states. From the latter we derive an approximation scheme valid in the thermodynamic limit of many particles. Mean-field results are shown to emerge as the correct leading-order approximation to exact calculations in the same subspace.

description: The Hubbard model describes a lattice system of quantum particles with local (on-site) interactions. Its free energy is analytic when βt is small, or βt^2/U is small; here, βis the inverse temperature, U the on-site repulsion and t the hopping coefficient. For more general models with Hamiltonian H = V + T where V involves local terms only, the free energy is analytic when β||T|| is small, irrespectively of V. The Gibbs state exists in the thermodynamic limit, is exponentially clustering and thermodynamically stable. These properties are rigorously established in this paper.

description: Even with several advancements in multilingual modeling, it is challenging to recognize multiple languages using a single neural model, without knowing the input language and most multilingual models assume the availability of the input language. In this work, we propose a novel bilingual end-to-end (E2E) modeling approach, where a single neural model can recognize both languages and also support switching between the languages, without any language input from the user. The proposed model has shared encoder and prediction networks, with language-specific joint networks that are combined via a self-attention mechanism. As the language-specific posteriors are combined, it produces a single posterior probability over all the output symbols, enabling a single beam search decoding and also allowing dynamic switching between the languages. The proposed approach outperforms the conventional bilingual baseline with 13.3%, 8.23% and 1.3% word error rate relative reduction on Hindi, English and code-mixed test sets, respectively.

description: Recently, the rise of large-scale vision-language pretrained models like CLIP, coupled with the technology of Parameter-Efficient FineTuning (PEFT), has captured substantial attraction in video action recognition. Nevertheless, prevailing approaches tend to prioritize strong supervised performance at the expense of compromising the models' generalization capabilities during transfer. In this paper, we introduce a novel Multimodal, Multi-task CLIP adapting framework named \name to address these challenges, preserving both high supervised performance and robust transferability. Firstly, to enhance the individual modality architectures, we introduce multimodal adapters to both the visual and text branches. Specifically, we design a novel visual TED-Adapter, that performs global Temporal Enhancement and local temporal Difference modeling to improve the temporal representation capabilities of the visual encoder. Moreover, we adopt text encoder adapters to strengthen the learning of semantic label information. Secondly, we design a multi-task decoder with a rich set of supervisory signals to adeptly satisfy the need for strong supervised performance and generalization within a multimodal framework. Experimental results validate the efficacy of our approach, demonstrating exceptional performance in supervised learning while maintaining strong generalization in zero-shot scenarios.

description: The production and consumption of information about Bitcoin and other digital-, or 'crypto'-, currencies have grown together with their market capitalisation. However, a systematic investigation of the relationship between online attention and market dynamics, across multiple digital currencies, is still lacking. Here, we quantify the interplay between the attention towards digital currencies in Wikipedia and their market performance. We consider the entire edit history of currency-related pages, and their view history from July 2015. First, we quantify the evolution of the cryptocurrency presence in Wikipedia by analysing the editorial activity and the network of co-edited pages. We find that a small community of tightly connected editors is responsible for most of the production of information about cryptocurrencies in Wikipedia. Then, we show that a simple trading strategy informed by Wikipedia views performs better, in terms of returns on investment, than classic baseline strategies for most of the covered period. Our results contribute to the recent literature on the interplay between online information and investment markets, and we anticipate it will be of interest for researchers as well as investors.

description: We explore simple models aimed at the study of social contagion, in which contagion proceeds through two stages. When coupled with demographic turnover, we show that two-stage contagion leads to nonlinear phenomena which are not present in the basic `classical' models of mathematical epidemiology. These include: bistability, critical transitions, endogenous oscillations, and excitability, suggesting that contagion models with stages could account for some aspects of the complex dynamics encountered in social life. These phenomena, and the bifurcations involved, are studied by a combination of analytical and numerical means.

description: A ME-EC method that uses transient isotachophoresis and a Pt black-modifed working electrode to enhance the signal and detect nitrite as well as other electrochemically active species was reported. First, a stacking method to enhance the signal of nitrite through the addition of NaCl to the run buﬀer was developed that provided a 5.2-fold decrease in the LOD for nitrite. Then, a procedure to modify a Pt working electrode with Pt black for the detection of nitrite was optimized. This electrode modification was then coupled with a ME-EC method, and a signal enhancement for nitrite, hydrogen peroxide, and ascorbic acid was obtained. The use of a Pt black-modified working electrode resulted in an increased sensitivity for nitrite. This method was then used to detect nitrite as an indicator of NO production in a bulk cell lysate sample. The incorporation of the tITP system and Pt black-modified working electrode improved the method previously reported by our group by increasing the sensitivity and decreasing the LOD.

A universal flow invariant in quantum field theory

Publisher: name: arXiv
Year: 2001
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: A flow invariant is a quantity depending only on the UV and IR conformal fixed points and not on the flow connecting them. Typically, its value is related to the central charges a and c. In classically-conformal field theories, scale invariance is broken by quantum effects and the flow invariant a_{UV}-a_{IR} is measured by the area of the graph of the beta function between the fixed points. There exists a theoretical explanation of this fact. On the other hand, when scale invariance is broken at the classical level, it is empirically known that the flow invariant equals c_{UV}-c_{IR} in massive free-field theories, but a theoretical argument explaining why it is so is still missing. A number of related open questions are answered here. A general formula of the flow invariant is found, which holds also when the stress tensor has improvement terms. The conditions under which the flow invariant equals c_{UV}-c_{IR} are identified. Several non-unitary theories are used as a laboratory, but the conclusions are general and an application to the Standard Model is addressed. The analysis of the results suggests some new minimum principles, which might point towards a better understanding of quantum field theory.

description: Lyman Limit systems (LLSs) trace the low-density circumgalactic medium and the most dense regions of the intergalactic medium, so their number density and evolution at high redshift, just after reionisation, are important to constrain. We present a survey for LLSs at high redshifts, $z_{\rm LLS} =3.5$--5.4, in the homogeneous dataset of 153 optical quasar spectra at $z \sim 5$ from the Giant Gemini GMOS survey. Our analysis includes detailed investigation of survey biases using mock spectra which provide important corrections to the raw measurements. We estimate the incidence of LLSs per unit redshift at $z \approx 4.4$ to be $\ell(z) = 2.6 \pm 0.4$. Combining our results with previous surveys at $z_{\rm LLS} <4$, the best-fit power-law evolution is $\ell(z) = \ell_* [(1+z)/4]^α$ with $\ell_* = 1.46 \pm 0.11$ and $α= 1.70 \pm 0.22$ (68\% confidence intervals). Despite hints in previous $z_{\rm LLS} <4$ results, there is no indication for a deviation from this single power-law soon after reionization. Finally, we integrate our new results with previous surveys of the intergalactic and circumgalactic media to constrain the hydrogen column density distribution function, $f(N_{\rm HI},X)$, over 10 orders of magnitude. The data at $z \sim 5$ are not well described by the $f(N_{\rm HI},X)$ model previously reported for $z \sim 2$--3 (after re-scaling) and a 7-pivot model fitting the full $z \sim 2$--5 dataset is statistically unacceptable. We conclude that there is significant evolution in the shape of $f(N_{\rm HI},X)$ over this $\sim$2 billion year period.

description: Bilayer two-dimensional electron systems formed by a thin barrier in the GaAs buffer of a standard heterostructure were investigated by magnetotransport measurements. In magnetic fields oriented parallel to the electron layers, the magnetoresistance exhibits an oscillation associated with the depopulation of the higher occupied subband and the field-induced transition into a decoupled bilayer. Shubnikov-de Haas oscillations in slightly tilted magnetic fields allow to reconstruct the evolution of the electron concentration in the individual subbands as a function of the in-plane magnetic field. The characteristics of the system derived experimentally are in quantitative agreement with numerical self-consistent-field calculations of the electronic structure.

description: In melt-blowing processes mico- and nanofibers are produced by the extrusion of polymeric jets into a directed, turbulent high-speed airflow. Up to now the physical mechanism for the drastic jet thinning is not fully understood, since in the existing literature the numerically computed/predicted fiber thickness differs several orders of magnitude from those experimentally measured. Recent works suggest that this discrepancy might arise from the neglect of the turbulent aerodynamic fluctuations in the simulations. In this paper we confirm this suggestion numerically. Due to the complexity of the process direct numerical simulations of the multiscale-multiphase problem are not possible. Hence, we develop a numerical framework for a growing fiber in turbulent air that makes the simulation of industrial setups feasible. For this purpose we employ an asymptotic viscoelastic model for the fiber. The turbulent effects are taken into account by a stochastic aerodynamic force model where the underlying velocity fluctuations are reconstructed from a $k$-$ε$ turbulence description of the airflow. Our numerical results show the significance of the turbulence on the jet thinning and give fiber diameters of realistic order of magnitude.

We construct an analysis based on quantities such as $H_T$ and the numbers of jets which are tagged as boosted tops, $W$s, or containing $b$-tags, and show that the LHC with 3~ab$^{-1}$ can discover top partners with masses up to around 2.5 TeV in the six top signature.

description: The Human-Computer Interaction (HCI) community has consistently focused on the experiences of users moderated by social media platforms. Recently, scholars have noticed that moderation practices could perpetuate biases, resulting in the marginalization of user groups undergoing moderation. However, most studies have primarily addressed marginalization related to issues such as racism or sexism, with little attention given to the experiences of people with disabilities. In this paper, we present a study on the moderation experiences of blind users on TikTok, also known as "BlindToker," to address this gap. We conducted semi-structured interviews with 20 BlindTokers and used thematic analysis to analyze the data. Two main themes emerged: BlindTokers' situated content moderation experiences and their reactions to content moderation. We reported on the lack of accessibility on TikTok's platform, contributing to the moderation and marginalization of BlindTokers. Additionally, we discovered instances of harassment from trolls that prompted BlindTokers to respond with harsh language, triggering further moderation. We discussed these findings in the context of the literature on moderation, marginalization, and transformative justice, seeking solutions to address such issues.

description: We propose an explicit construction of the deformation quantization of the general second-class constrained system, which is covariant with respect to local coordinates on the phase space. The approach is based on constructing the effective first-class constraint (gauge) system equivalent to the original second-class one and can also be understood as a far-going generalization of the Fedosov quantization. The effective gauge system is quantized by the BFV-BRST procedure. The star product for the Dirac bracket is explicitly constructed as the quantum multiplication of BRST observables. We introduce and explicitly construct a Dirac bracket counterpart of the symplectic connection, called the Dirac connection. We identify a particular star product associated with the Dirac connection for which the constraints are in the center of the respective star-commutator algebra. It is shown that when reduced to the constraint surface, this star product is a Fedosov star product on the constraint surface considered as a symplectic manifold.

From static repository to dynamic archive: An exploration of the evolution of NSIDC data services
Creators: name: Collins, Julia
Publisher: name: Zenodo

Subjects: data discovery, data access, use case development

description: As NSIDC celebrates its 30th anniversary, it does so in a computing environment unimaginable at its beginning. The reach of the Internet, and more specifically the protocols it supports (such as HTTP and FTP) enables options for data discovery and delivery that were impossible at NSIDC's inception. This changing cyber-infrastructure allows us to explore new ways of thinking about how a data archive can serve its users. It also requires us to respond to changes in the research questions being posed and examined, and the
 corresponding requirements for data discovery and access in the research process. Increasingly, climate research requires an interdisciplinary approach to answering its questions. Not only do users need help navigating the expanding volumes of data available at any one data archive, they also need to be able to use the data we provide in conjunction with data from other centers and disciplines. NSIDC's challenge is to position ourselves to respond to changes in user access patterns, analysis tools and requested data formats, while at the same time maintaining the integrity of the data center holdings and plan for long term data stewardship. This presentation will review work in progress to evolve NSIDC data systems and services. It will examine the process used to assess our current data services and the conclusions from that assessment, the design and implementation of exploratory web-
 based projects which address our next-generation data delivery roles and responsibilities, and preliminary feedback on the results of those projects.
STRING SIMILARITY BASED ON PHONETIC IN GUJARATI LANGUAGE USING GUJSIM ALGORITHM

description: Searching using top 10 search engine1 to find “ગ ાંધીજી” or “ગ ન્ધીજી” and surprised to see the result which far differs from one to another. As in the Gujarati language, both strings are correct. Therefore, String similarity algorithm is useful for text mining applications while we generate index – saving space and time, both. Basically, string similarity compares each character from both strings but it may not give the accurate result on highly rich Gujarati language due to different kinds of writing styles which depend on matras, reph, vatu, and diacritics on simple and compound alphabets. GUJSIM (GUJarati SIMilarity) algorithm is the hybrid approach to do strings similarity for the Gujarati language. Here, the author compares 70 strings pairs and GUJSIM algorithm which gives optimum percentage result. This algorithm also helps to reduce the percentage of index based on the unique string.

Monte Carlo Study of the S=1/2 and S=1 Heisenberg Antiferromagnet on a Spatially Anisotropic Square Lattice

description: We present a quantum Monte Carlo study of a Heisenberg antiferromagnet on a spatially anisotropic square lattice, where the coupling strength in the x-direction ($J_x$) is different from that in the y-direction ($J_y$). By varying the anisotropy $α$ from 0 to 1, we interpolate between the one-dimensional chain and the two-dimensional isotropic square lattice. Both $S=1/2$ and S=1 systems are considered separately in order to facilitate comparison. The temperature dependence of the uniform susceptibility and the spin-spin correlation length are computed down to very low temperatures for various values of $α$. For S=1, the existence of a quantum critical point at $α^{S=1}_c=0.040(5)$ as well as the scaling of the spin gap is confirmed. Universal quantities predicted from the ${\cal O}(3)$ nonlinear $σ$ model agree with our results at $α=0.04$ without any adjustable parameters. On the other hand, the $S=1/2$ results are consistent with $α^{S=1/2}_c=0$, as discussed by a number of previous theoretical studies. Experimental implications for $S=1/2$ compounds such as Sr$_2$CuO$_3$ are also discussed.

description: The temperature dependence of the diffuse scattering fine structure from disordered equiatomic CuAu was studied using {\it in situ} x-ray scattering. In contrast to Cu$_3$Au the diffuse peak splitting in CuAu was found to be relatively insensitive to temperature. Consequently, no evidence for a divergence of the antiphase length-scale at the transition temperature was found. At all temperatures studied the peak splitting is smaller than the value corresponding to the CuAuII modulated phase. An extended Ginzburg-Landau approach is used to explain the temperature dependence of the diffuse peak profiles in the ordering and modulation directions. The estimated mean-field instability point is considerably lower than is the case for Cu$_3$Au.

description: Star-forming regions are usually studied in the context of Galactic surveys, but dedicated observations are sometimes needed when the study reaches beyond the survey area. Here, we studied the G345.5+1.5 region, which is located slightly above the Galactic plane, to understand its star formation properties. We combined the LABOCA and $^{12}$CO(4$-$3) transition line observations complemented with the Hi-GAL and $\it{Spitzer}$-GLIMPSE surveys to study the star formation toward this region. We used the Clumpfind algorithm to extract the clumps from the 870$μ$m and $^{12}$CO(4$-$3) data. Radio emission at 36cm was used to estimate the number of HII regions and to remove the contamination from the free-free emission at 870$μ$m. We employed color-color diagrams and spectral energy distribution slopes to distinguish between prestellar and protostellar clumps. We studied the boundedness of the clumps through the virial parameter. Finally, we estimated the star formation efficiency and star formation rate of the region and used the Schmidt-Kennicutt diagram to compare its ability to form stars. Of the 13 radio sources that we found using the MGPS-2 catalog, 7 are found to be associated with HII regions corresponding to late-B or early-O stars. We found 45 870$μ$m clumps, and 107 $^{12}$CO clumps. More than 50\% of the clumps are protostellar and bounded and are able to host star formation. High SFR and SFR density values are associated with the region, with an SFE of a few percent. With submillimeter, CO transition, and short-wavelength infrared observations, our study reveals a population of massive stars, protostellar and bound starless clumps, toward G345.5+1.5. This region is therefore actively forming stars, and its location in the starburst quadrant of the Schmidt-Kennicutt diagram is comparable to other star-forming regions found within the Galactic plane.
