description: Der Weg zu einer datenbasierten Kreislaufwirtschaft ist mit zahlreichen Herausforderungen verbunden. Die Frage, wie die großen Mengen an Daten, die in jedem Lebenszyklus-Schritt der Materialien oder Produkte anfallen, sicher gesammelt und gelagert werden können, steht dabei ebenso im Raum wie die Frage, wie ein nahtloser Austausch und Verständnis zwischen verschiedenen Systemen und Akteuren sichergestellt werden kann. Dies impliziert die Notwendigkeit der Gewährleistung der Interoperabilität der Daten. 

Ein möglicher Ansatz zur Lösung dieser Problematik könnte in der Verwendung standardisierter Materialpässe in Kombination mit den neuesten Entwicklungen im Bereich der künstlichen Intelligenz bestehen. Im Rahmen dieses Workshops erforschen wir zusammen, inwiefern die genannten Entwicklungen die Kreislaufwirtschaft fördern und vorantreiben können. Dabei wird auch der Einsatz großer Sprachmodelle (LLMs) berücksichtigt.   

 Im Rahmen dieses Workshops erfolgt zunächst eine Einführung der Teilnehmer*innen in die Grundlagen von Materialpässen. Darauf aufbauend wird ein Überblick über die Unterschiede zwischen Materialpässen und digitalen Produktpässen bzw. Gebäudepässen gegeben. Im Anschluss erfolgt eine gemeinsame Betrachtung des gegenwärtigen Stands der Standardisierung von MPs, wobei sowohl gegenwärtige als auch zukünftige Herausforderungen und Potenziale erörtert werden. Ein besonderes Augenmerk gilt dabei den Potenzialen, die sich aus der Anwendung künstlicher Intelligenz bzw. großer Sprachmodelle (LLMs) ergeben.

description: We consider a Josephson junction where the weak-link is formed by a non-centrosymmetric ferromagnet. In such a junction, the superconducting current acts as a direct driving force on the magnetic moment. We show that the a.c. Josephson effect generates a magnetic precession providing then a feedback to the current. Magnetic dynamics result in several anomalies of current-phase relations (second harmonic, dissipative current) which are strongly enhanced near the ferromagnetic resonance frequency.
Three western species of the genus Habenaria willd : their relationship and crossability
Creators: name: Fisher, Emmy H.
Publisher: name: University of British Columbia
Year: 2010

description: Relationship and interfertility of Habenaria dilatata (lursh) Hook.,H. hyperborea (L.) R.Br, and H. saccata Greene was studied. Intraspecific and interspecific crosses were made. Chromosome counts of the three species showed 21 pairs of chromosomes in the cells, except for a small green-flowered population from Manning Park with n = 42 which was considered tetraploid and possibly of hybrid origin. These counts agree with earlier ones for the three species. Since creation of the genus Habenaria Willd» these species have been included under tribe Ophrydeae, which now has been changed to Orchideae, subtribe Orchidinae to conform with the rulings of the International Code of Botanical Nomenclature (1959)* In spite of apparently close relationships the species maintain their distinctness, even when growing sym-patrically, indicating barriers to outcrossing, or for plants growing in northerly regions, a lack of pollinators. Autogamous tendencies have therefore developed and H. dilatata and H. hyperborea are outcrossing or autogamous when the need arises. H. saccata seems to be self-sterile. Microsporogenesis in the species studied follows that of other orchids. The archesporial cell directly becomes the spore mother cell. All descendants of this cell stay together and divide together, forming a massula or pollen packet. Pollen mitosis results in the 2-nucleate pollen grain which is shed as such. The generative nucleus divides in the pollen tube, producing the 2 sperm nuclei, as the tube enters the ovary. Only the chalazal megaspore is functional. Three simultaneous divisions produce the monosporic, 8-nucleate Polygonum-type embryo sac. Fusion of the polar nuclei is the rule and takes place before fertilization. Triple fusion follows, hut the primary endosperm nucleus begins to degenerate usually before the r-ypote starts to divide. An haustorial susy ensor develops, which does not take part in the construction of the embryo proper. The mature embryo is an un differentiated body of 50-60 cells, suspended in the air-filled cavity of the reticulate testa. It takes from 3-4 weeks from pollination to saturation of the embryo. Intraspecific crosses were all successful. Interspecific crosses produced a higher percentage of seed with well developed embryos in IT. hyperborea x H. saccata crosses than in crosses between H. riil tata and either of the 2 other species. The tetraploid plants were successful both as seed and pollen parents. Regular meiosis would indicate allopolyploid origin. Artificial pollinations showed that gene flow is possible and that artificial crosses are easy to make. In nature isolating mec'r an isms must rrevent the species from losing their identity although hybridization may take place under favourable conditions. Control plants of H. dilatata and H, hyperhorea not emasculated and not protected showed a full seed set, indicating autocamy, whereas unpollinated H. sancata yielded only empty seed.

Educare alla gioia

description: The hypotheses that the author intends to make in her article is that presently, Integral Education can be one of the approaches adopted for school education which can promote a sense of “well-being” and an inner joy for the students and the teachers, who are important constituents and investments in the educational process. Here one accepts that with an Integral vision for education, it is possible to educate and to grow because this approach follows the path of liberty and the “joy of the being”. Two aspects come to light through this investigation: the training of teachers as “guides” and the sense of “well-being” present in the “free” schools. The latter supports what the hypothesis states, consequent research too indicates the same, which is that freedom is a necessary component of education, for a holistic development of the child (physical, mental and spiritual): that it promotes and helps recreate the experience of “Joy of being”. The conclusion that this article draws is based on the introductory elements, the prolegomena to theories of education: “Joy”, intended as the “guiding emotion” in education can also act as a condition of union with the Absolute.

We compare our results with the close-to-threshold experimental data. The pion-pion rescattering contribution is found there to be negligible. The predictions for future experiments with PANDA detector at High Energy Storage Ring (HESR) in GSI Darmstadt are presented. It is discussed how to cut off the dominant Roper resonance and double-$Δ$ excitation mechanisms leading to the $p p π^+ π^-$ channel in final state. Differential distributions in momentum transfers, transverse momentum, effective two-pions mass, relative azimuthal angle between pions, and pion rapidities are presented.

description: Datenmodellierung - Wie lassen sich Makro- und Sektormodelle verbinden? 

Modellierungen auf Makro-Ebene bauen in der Regel auf volkswirtschaftlichen Statistiken auf, denen eine genormte Klassifizierung zugrunde liegt. Dies ist oftmals anders, wenn primäre und sekundäre Stoffflüsse für einen Sektor modelliert werden: die Definition, was ein Sektor ist und was zu einem Sektor gehört bzw. mitgezählt wird, variiert je nach Fragestellung. Dies erschwert nicht nur die Vergleichbarkeit von sektoralen Studien, sondern auch die Einordnung von sektoralen Ergebnissen in ein volkswirtschaftliches Gesamtbild. Auch die Verbindungen von Sektoranalysen und gesamtwirtschaftlichen Analysen werden dadurch erschwert.  

  

In diesem Workshop wollen wir uns daher mit Fragen beschäftigen und Erfahrungen und Meinungen austauschen: 

Wie unterschiedlich oder gleich sind sektorale Studien zu CE?  

Welche Herausforderungen stellen sich durch die Unterschiedlichkeit? 

Welche Unterschiedlichkeit ist ein Problem, das es zu beheben gilt? Oder ist anything goes langfristig die Lösung? 

Gibt es minimale Standards oder eine gute Praxis der Dokumentation, die wir sinnvoll finden?

description: UO2 and (U,Pu)O2 solid solutions (the so-called MOX) nowadays are used as commercial nuclear fuels in many countries. One of the safety issues during the storage of these fuels is related to their self-irradiation that produces and accumulates point defects and helium therein. We present density functional theory (DFT) calculations for UO2, PuO2 and MOX containing He atoms in octahedral interstitial positions. In particular, we calculated basic MOX properties and He incorporation energies as functions of Pu concentration within the spin-polarized, generalized gradient approximation (GGA) DFT calculations. We also included the on-site electron correlation corrections using the Hubbard model (in the framework of the so-called DFT+U approach). We found that PuO2 remains semiconducting with He in the octahedral position while UO2 requires a specific lattice distortion. Both materials reveal a positive energy for He incorporation, which, therefore, is an exothermic process. The He incorporation energy increases with the Pu concentration in the MOX fuel.

description: Language is an essential factor of emancipation. Unfortunately, most of the more than 2,000 African languages are low-resourced. The community has recently used machine translation to revive and strengthen several African languages. However, the trained models are often bilingual, resulting in a potentially exponential number of models to train and maintain to cover all possible translation directions. Additionally, bilingual models do not leverage the similarity between some of the languages. Consequently, multilingual neural machine translation (NMT) is gaining considerable interest, especially for low-resourced languages. Nevertheless, its adoption by the community is still limited. This paper introduces English2Gbe, a multilingual NMT model capable of translating from English to Ewe or Fon. Using the BLEU, CHRF, and TER scores computed with the Sacrebleu (Post, 2018) package for reproducibility, we show that English2Gbe outperforms bilingual models (English to Ewe and English to Fon) and gives state-of-the-art results on the JW300 benchmark for Fon established by Nekoto et al. (2020). We hope this work will contribute to the massive adoption of Multilingual models inside the community. Our code is made accessible from Github.

description: CE has arrived at the company floor rather quickly. CSRD demands CE-specific indicators to be reported, the new ISO 59020 includes a whole range of CE indicators and CE-related decisions in product design and production also require trustworthy and comparable CE data compatible with and integrated into “conventional” decision support systems. The workshop aims at elaborating questions such as 

What CE data / indicators are companies supposed to report / disclose in the future? 

Which CE data / indicators are actually useful for companies to support decisions towards CE? 

What are the most important data sources for CE on the company floor?  

 The workshop consists of three parts. In the beginning, the two facilitators will provide brief insights and impulses to the questions above. Thereafter, the participants will choose topics they want to further discuss and elaborate in world café formats. Those results are presented and discussed in the concluding part of the workshop.

description: Performing hundreds of test runs and a source-code analysis, we empirically identified improved parameter configurations for the CryptoMiniSat (CMS) 5 for solving cryptographic CNF instances originating from algebraic known-plaintext attacks on 3 rounds encryption of the Small AES-64 model cipher SR$(3, 4, 4, 4)$. We finally became able to reconstruct 64-bit long keys in under an hour real time which, to our knowledge, has never been achieved so far. Especially, not without any assumptions or previous knowledge of key-bits (for instance in the form of side-channels, as in \cite{Mohamed2012algebraicSCA}). A statistical analysis of the non-deterministic solver runtimes was carried out and command line parameter combinations were defined to yield best runtimes which ranged from under an hour to a few hours in median at the beginning. We proceeded using an Automatic Algorithm Configuration (AAC) tool to systematically extend the search for even better solver configurations with success to deliver even shorter solving times. In this work we elaborate on the systematics we followed to reach our results in a traceable and reproducible way. The ultimate focus of our investigations is to find out if CMS, when appropriately tuned, is indeed capable to attack even bigger and harder problems than the here solved ones. For the domain of cryptographic research, the duration of the solving time plays an inferior role as compared to the practical feasibility of finding a solution to the problem. The perspective scalability of the here presented results is the object of further investigations.

This method is much more robust than approaches that calculate the group velocity directly and can be generalized to include additional physics, e.g. magnetic geometry. The results are verified with the gyrokinetic code GYRO [J. Candy and R. E. Waltz, J. Comp. Phys. 186, pp. 545-581 (2003)], the two-fluid code NLET [K. Hallatschek and A. Zeiler, Physics of Plasmas 7, pp. 2554-2564 (2000)], and analytical calculations. GAM propagation must be kept in mind when discussing the windows of GAM activity observed experimentally and the match between linear theory and experimental GAM frequencies.

description: The measurements of direct photons in $1.0 < p_{T} < 5.0 $GeV/$c$ for p+p and Au+Au collisions have been made through the virtual photon method at PHENIX. The fraction of the virtual direct photon component to the inclusive $e^{+}e^{-}$ yield is determined by a shape analysis using the $e^{+}e^{-}$ mass spectra in $m_{ee} < 300 $MeV/$c^{2}$ for $1.0 < p_{T} < 5.0 $GeV/$c$. The real direct photon spectra in p+p and Au+Au collisions are obtained from the virtual direct photon fractions, and a significant excess over a binary-scaled p+p result is seen in Au+Au collisions. Hydrodynamical models which reproduce the Au+Au result indicate the initial temperature of the matter is higher than the critical temperature of QGP. The d+Au data taken in 2008 are promising to evaluate the contribution of the nuclear effects because of its large statistics.

DEVELOPMENT AND VALIDATION OF A STABILITY-INDICATING HPLC ASSAY METHOD FOR FAMCICLOVIR IN MARKETED FORMULATIONS
Creators: name: Dr. Chandrakant P. Suryawanshi , Dr. Rajendra D. Wagh
Publisher: name: Zenodo
Year: 2024

description: The study focused on developing and validating a stability-indicating HPLC method for the assay of Famciclovir in pharmaceutical formulations. The identity of Famciclovir was confirmed through UV-visible wavelength scanning and FT-IR spectroscopy, revealing characteristic peaks aligned with its chemical structure. The UV-Visible spectra displayed a maximum absorption at 315 nm, with a highly linear calibration curve (R² = 0.998) across varying concentrations. Method optimization included fine-tuning chromatographic conditions, leading to successful separation using an Eclipse Plus column and a mobile phase of acetonitrile, methanol, and glacial acetic acid (45:25:15 v/v/v) at a flow rate of 1 ml/min.

Validation of the method showed excellent linearity, accuracy, precision, and robustness, supported by system suitability tests that ensured appropriate chromatographic performance. The assay of Famciclovir in pharmaceutical formulations demonstrated consistent accuracy and precision over three consecutive days. Forced degradation studies, including acid/base hydrolysis, oxidation, and exposure to thermal and photolytic stress, confirmed the method’s stability-indicating properties. Despite significant degradation, Famciclovir was effectively separated from its degradation products, confirming the specificity of the developed method.

description: A model for epidemic spreading on rewiring networks is introduced and analyzed for the case of scale free steady state networks. It is found that contrary to what one would have naively expected, the rewiring process typically tends to suppress epidemic spreading. In particular it is found that as in static networks, rewiring networks with degree distribution exponent $γ>3$ exhibit a threshold in the infection rate below which epidemics die out in the steady state. However the threshold is higher in the rewiring case. For $2

description: Human-performed annotation of sentences in legal documents is an important prerequisite to many machine learning based systems supporting legal tasks. Typically, the annotation is done sequentially, sentence by sentence, which is often time consuming and, hence, expensive. In this paper, we introduce a proof-of-concept system for annotating sentences "laterally." The approach is based on the observation that sentences that are similar in meaning often have the same label in terms of a particular type system. We use this observation in allowing annotators to quickly view and annotate sentences that are semantically similar to a given sentence, across an entire corpus of documents. Here, we present the interface of the system and empirically evaluate the approach. The experiments show that lateral annotation has the potential to make the annotation process quicker and more consistent.

description: We demonstrate the existence of heterotic-string vacua that are free of massless exotic fields. The need to break the non-Abelian GUT symmetries in k=1 heterotic-string models by Wilson lines, while preserving the GUT embedding of the weak-hypercharge and the GUT prediction sin^2θ_w(M(GUT))=3/8, necessarily implies that the models contain states with fractional electric charge. Such states are severely restricted by observations, and must be confined or sufficiently massive and diluted. We construct the first quasi-realistic heterotic-string models in which the exotic states do not appear in the massless spectrum, and only exist, as they must, in the massive spectrum. The SO(10) GUT symmetry is broken to the Pati-Salam subgroup. Our PS heterotic-string models contain adequate Higgs representations to break the GUT and electroweak symmetry, as well as colour Higgs triplets that can be used for the missing partner mechanism. By statistically sampling the space of Pati-Salam vacua we demonstrate the abundance of quasi--realistic three generation models that are completely free of massless exotics, rendering it plausible that obtaining realistic Yukawa couplings may be possible in this space of models.

Paradigm shifts in solar dynamo modeling

Year: 2009
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Selected topics in solar dynamo theory are being highlighted. The possible relevance of the near-surface shear layer is discussed. The role of turbulent downward pumping is mentioned in connection with earlier concerns that a dynamo-generated magnetic field would be rapidly lost from the convection zone by magnetic buoyancy. It is argued that shear-mediated small-scale magnetic helicity fluxes are responsible for the success of some of the recent large-scale dynamo simulations. These fluxes help in disposing of excess small-scale magnetic helicity. This small-scale magnetic helicity, in turn, is generated in response to the production of an overall tilt in each Parker loop. Some preliminary calculations of this helicity flux are presented for a system with uniform shear. In the Sun the effects of magnetic helicity fluxes may be seen in coronal mass ejections shedding large amounts of magnetic helicity.

description: The progress made by the entrepreneurial university, which is a newly emerging category in Hungarian higher education after its change of model, has not only deepened relations between universities and the industry and intensified the technology and knowledge transfer processes, but also increased the role of universities in shaping regional innovation policy. This transformation places co-operation between the actors of the regional innovation ecosystem and the relationships between the economic, governmental and academic systems into a new framework. The purpose of this paper is to describe the process of the change in the model through a specific example, and to outline the future possibilities of university involvement in the currently changing Hungarian innovation policy system.
Shockwaves and deep inelastic scattering within the gauge/gravity duality

description: Within the gauge/gravity correspondence, we discuss the general formulation of the shockwave metric which is dual to a 'nucleus' described by the strongly-coupled N=4 SYM theory in the limit where the number of colors Nc is arbitrarily large. We emphasize that the 'nucleus' must possess Nc^2 degrees of freedom per unit volume, so like a finite-temperature plasma, in order for a supergravity description to exist. We critically reassess previous proposals for introducing transverse inhomogeneity in the shockwave and formulate a new proposal in that sense, which involves no external source but requires the introduction of an 'infrared' cutoff which mimics confinement. This cutoff however plays no role when the shockwave is probed by a highly virtual projectile, so like in deep inelastic scattering. We consider two such projectiles, the dilaton and the R-current, and compute the respective structure functions including unitarity corrections. We find that there are no leading-twist contributions to the structure functions at high virtuality, meaning that there are no point-like constituents in the strongly coupled 'nucleus'. In the black-disk regime at low virtuality, the structure functions are suggestive of parton saturation with occupation numbers of order one. The saturation momentum Qs grows with the energy like Qs^2 ~ 1/x (with x the Bjorken variable), which is the hallmark of graviton exchanges and is also necessary for the fulfillment of the energy-momentum sum rules.

description: We have obtained deep optical spectrophotometry of 16 planetary nebulae in M33, mostly located in the central two kpc of the galaxy, with the Subaru and Keck telescopes. We have derived electron temperatures and chemical abundances from the detection of the [OIII]4363 line for the whole sample. We have found one object with an extreme nitrogen abundance, 12+log(N/H)=9.20, accompanied by a large helium content. After combining our data with those available in the literature for PNe and HII regions, we have examined the behavior of nitrogen, neon, oxygen and argon in relation to each other, and as a function of galactocentric distance. We confirm the good correlation between Ne/H and O/H for PNe in M33. Ar/H is also found to correlate with O/H. This strengthens the idea that at the metallicity of the bright PNe analyzed in M33, which is similar to that found in the LMC, these elements have not been significantly modified during the dredge-up processes that take place during the AGB phase of their progenitor stars. We find no significant oxygen abundance offset between PNe and HII regions at any given galactocentric distance, despite the fact that these objects represent different age groups in the evolution of the galaxy. Combining the results from PNe and HII regions, we obtain a representative slope of the ISM alpha-element (O, Ar, Ne) abundance gradient in M33 of -0.025 +/- 0.006 dex/kpc. Both PNe and HII regions display a large abundance dispersion at any given distance from the galactic center. We find that the N/O ratio in PNe is enhanced, relative to the HII regions, by approximately 0.8 dex.

description: Clusters of galaxies are the largest gravitationally bound objects in the Universe, containing about 10^15 solar masses of hot (10^8 K) gas, galaxies and dark matter in a typical volume of about 10 Mpc^3. Magnetic fields and relativistic particles are mixed with the gas as revealed by giant radio haloes, which arise from diffuse, megaparsec-scale synchrotron radiation at cluster center. Radio haloes require that the emitting electrons are accelerated in situ (by turbulence), or are injected (as secondary particles) by proton collisions into the intergalactic medium. They are found only in a fraction of massive clusters that have complex dynamics, which suggests a connection between these mechanisms and cluster mergers. Here we report a radio halo at low frequencies associated with the merging cluster Abell 521. This halo has an extremely steep radio spectrum, which implies a high frequency cut-off; this makes the halo difficult to detect with observations at 1.4 GHz (the frequency at which all other known radio haloes have been best studied). The spectrum of the halo is inconsistent with a secondary origin of the relativistic electrons, but instead supports turbulent acceleration, which suggests that many radio haloes in the Universe should emit mainly at low frequencies.

description: As one of the most prevalent neurodegenerative disorders, Parkinson's disease (PD) has a significant impact on the fine motor skills of patients. The complex interplay of different articulators during speech production and realization of required muscle tension become increasingly difficult, thus leading to a dysarthric speech. Characteristic patterns such as vowel instability, slurred pronunciation and slow speech can often be observed in the affected individuals and were analyzed in previous studies to determine the presence and progression of PD. In this work, we used a phonetic recognizer trained exclusively on healthy speech data to investigate how PD affected the phonetic footprint of patients. We rediscovered numerous patterns that had been described in previous contributions although our system had never seen any pathological speech previously. Furthermore, we could show that intermediate activations from the neural network could serve as feature vectors encoding information related to the disease state of individuals. We were also able to directly correlate the expert-rated intelligibility of a speaker with the mean confidence of phonetic predictions. Our results support the assumption that pathological data is not necessarily required to train systems that are capable of analyzing PD speech.

description: Recent works by Brown et al and Borras et al have explored numerical optimisation procedures to search for highly entangled multi-qubit states according to some computationally tractable entanglement measure. We present an alternative scheme based upon the idea of searching for states having not only high entanglement but also simple algebraic structure. We report results for 4, 5, 6, 7 and 8 qubits discovered by this approach, showing that many of such states do exist. In particular, we find a maximally entangled 6-qubit state with an algebraic structure simpler than the best results known so far. For the case of 7, we discover states with high, but not maximum, entanglement and simple structure, as well as other desirable properties. Some preliminary results are shown for the case of 8 qubits.

description: IL-1 blockers are beneficial in inflammation-associated pathologies, such as rheumatoid arthritis (Mertens 2009) and possibly also in the subgroup of patients with severe sepsis where the inflammasome pathway is involved (Shakoory 2016). Similar benefits were reported in children with secondary macrophage activation syndrome, including cases triggered by viral infections (Mehta 2020b). In this review we aim to assess the effectiveness of IL-1 blocking agents compared to placebo, standard of care or no treatment on outcomes in patients with COVID-19. This review is part of a larger project: the COVID-NMA project (Boutron 2020a). The COVID-NMA project aims to provide decision-makers with a complete, high-quality and up-to-date synthesis of evidence on interventions for the prevention and treatment of COVID 19. For this purpose, we perform a living mapping of all registered randomized controlled trials and a living evidence synthesis of data from RCTs. We developed a master protocol on the effect of all interventions for the prevention and treatment of COVID-19 (first published on April 8, 2020; an update on May 11, 2020, June 17, 2020, and September 8, 2020) (Boutron 2020b). We set-up a platform (https://covid-nma.com) where all our results are made available and updated weekly.
Comparative Study of BCS-BEC Crossover Theories above $T_c$: the Nature of the Pseudogap in Ultra-Cold Atomic Fermi Gases

description: This paper presents a comparison of two finite-temperature BCS-Bose Einstein condensation (BEC) crossover theories above the transition temperature: Nozieres Schmitt-Rink (NSR) theory and finite $T$-extended BCS-Leggett theory. The comparison is cast in the form of numerical studies of the behavior of the fermionic spectral function both theoretically and as constrained by (primarily) radio frequency (RF) experiments. Both theories include pair fluctuations and exhibit pseudogap effects, although the nature of this pseudogap is very different. The pseudogap in finite $T$-extended BCS-Leggett theory is found to follow a BCS-like dispersion which, in turn, is associated with a broadened BCS-like self energy, rather more similar to what is observed in high temperature superconductors (albeit, for a d-wave case). The fermionic quasi-particle dispersion is different in NSR theory and the damping is considerably larger. We argue that the two theories are appropriate in different temperature regimes with the BCS-Leggett approach more suitable nearer to condensation. There should, in effect, be little difference at higher $T$ as the pseudogap becomes weaker and where the simplifying approximations used in the BCS-Leggett approach break down. On the basis of momentum-integrated radio frequency studies of unpolarized gases, it would be difficult to distinguish which theory is the better. A full comparison for polarized gases is not possible since there is claimed to be inconsistencies in the NSR approach (not found in the BCS-Leggett scheme). Future experiments along the lines of momentum resolved experiments look to be very promising in distinguishing the two theories.

Dynamics of domain growth driven by dipolar interactions in a perpendicularly magnetized ultrathin film

description: Measurements of the ac magnetic susceptibility of perpendicularly magnetized Fe/2ML Ni/W(110) ultrathin films show a clear signature of the dynamics of domain growth and domain density changes in the striped domain pattern that this system supports. The susceptibility peak measured at different constant heating rates in the range 0.20 K/s < R < 0.70 K/s shifts to higher temperature as the heating rate is increased. Analysis using a relaxation model demonstrates quantitatively that the dynamics is driven by a non-equilibrium domain density at (nearly) zero field (i.e. by dipole interactions), and that the temperature shift is due to a response time determined by the pinning of local domain wall segments by structural defects. The fundamental time scale for relaxation of the domain density driven by dipole interactions is of order 10^5 times slower than the fundamental time scale for an individual Barkhausen step driven by an applied field. The increase in the fundamental time scale reflects the relative size of dipole and Zeeman energies, and the need for the correlated motion of many local domain wall segments to affect domain growth.

Estimating the Marginal Effect of a Continuous Exposure on an Ordinal Outcome using Data Subject to Covariate-Driven Treatment and Visit Processes

description: In the statistical literature, a number of methods have been proposed to ensure valid inference about marginal effects of variables on a longitudinal outcome in settings with irregular monitoring times. However, the potential biases due to covariate-driven monitoring times and confounding have rarely been considered simultaneously, and never in a setting with an ordinal outcome and a continuous exposure. In this work, we propose and demonstrate a methodology for causal inference in such a setting, relying on a proportional odds model to study the effect of the exposure on the outcome. Irregular observation times are considered via a proportional rate model, and a generalization of inverse probability of treatment weights is used to account for the continuous exposure. We motivate our methodology by the estimation of the marginal (causal) effect of the time spent on video or computer games on suicide attempts in the Add Health study, a longitudinal study in the United States. Although in the Add Health data, observation times are pre-specified, our proposed approach is applicable even in more general settings such as when analyzing data from electronic health records where observations are highly irregular. In simulation studies, we let observation times vary across individuals and demonstrate that not accounting for biasing imbalances due to the monitoring and the exposure schemes can bias the estimate for the marginal odds ratio of exposure.

description: We report a solution of the inverse Lagrangian problem for the first order Riccati differential equation by means of an analogy with the Friedmann equation of a suitable Friedmann-Lemaître-Robertson-Walker universe in general relativity. This analogous universe has fine-tuned parameters and is unphysical, but it suggests a Lagrangian and a Hamiltonian for the Riccati equation and for the many physical systems described by it.

description: :- These days, when an accident happens, people either hide from the emergency services or cause a lot of disturbance while reporting it, or the accident goes unreported and by the time help arrives, it’s too late. A comprehensive system has been developed to actively detect all types of traffic accidents and notify the appropriate parties. In the event of an accident, this includes the closest police station, hospitals, general ambulances, the registered owner of the vehicle involved in the accident, and their emergency contacts. In the event of a hit-and-run, the police can obtain the vehicle number of the accused vehicle. Numerous applications exist for vehicle detection in aerial pictures, and most vehicle detection techniques employ the bounding-box approach for localization. Using a private dataset, a convolutional neural network is proposed in this letter to detect cars. Based on experimental data, CNN performs better, with an accuracy rate of 94.54%.
