description: We study the helicity and chirality transitions of a high-energy neutrino propagating in a Schwarzschild space-time background. Using both traditional Schwarzschild and isotropic spherical co-ordinates, we derive an ultrarelativistic approximation of the Dirac Hamiltonian to first-order in the neutrino's rest mass, via a generalization of the Cini-Touschek transformation that incorporates non-inertial frame effects due to the noncommutative nature of the momentum states in curvilinear co-ordinates. Under general conditions, we show that neutrino's helicity is not a constant of the motion in the massless limit due to space-time curvature, while the chirality transition rate still retains an overall dependence on mass. We show that the chirality transition rate generally depends on the zeroth-order component of the neutrino's helicity transition rate under the Cini-Touschek transformation. It is also shown that the chiral current for high-energy neutrinos is altered by corrections due to curvature and frame-dependent effects, but should have no significant bearing on the chiral anomaly in curved space-time. We determine the upper bound for helicity and chirality transitions near the event horizon of a black hole. The special case of a weak-field approximation is also considered, which includes the gravitational analogue of Berry's phase first proposed by Cai and Papini. Finally, we propose a method for estimating the absolute neutrino mass and the number of right-handed chiral states from the expectation values of the helicity and chirality transition rates in the weak-field limit.

description: Time-delayed feedback control, attributed to Pyragas (1992 Physics Letters 170(6) 421-428), is a method known to stabilise periodic orbits in low dimensional chaotic dynamical systems. A system of the form $\dot{\mathbf{x}}(t)=f(\mathbf{x})$ has an additional term $G(\mathbf{x}(t)-\mathbf{x}(t-T))$ introduced where $G$ is some `gain matrix' and $T$ a time delay. The form of the delay term is such that it will vanish for any orbit of period $T,$ therefore making it also an orbit of the uncontrolled system. This non-invasive feature makes the method attractive for stabilising exact coherent structures in fluid turbulence. Here we begin by validating the method for the basic flow in Kolmogorov flow; a two-dimensional incompressible Navier-Stokes flow with a sinusoidal body force. The linear predictions for stabilisation are well captured by direct numerical simulation. By applying an adaptive method to adjust the streamwise translation of the delay, a known travelling wave solution is able to be stabilised up to relatively high Reynolds number. We discover that the famous `odd-number' limitation of this time-delayed feedback method can be overcome in the fluid problem by using the symmetries of the system. This leads to the discovery of 8 additional exact coherent structures which can be stabilised with this approach. This means that certain unstable exact coherent structures can be obtained by simply time-stepping a modified set of equations, thus circumventing the usual convergence algorithms.

description: Many important differential equations model quantities whose value must remain positive or stay in some bounded interval. These bounds may not be preserved when the model is solved numerically. We propose to ensure positivity or other bounds by applying Runge-Kutta integration in which the method weights are adapted in order to enforce the bounds. The weights are chosen at each step after calculating the stage derivatives, in a way that also preserves (when possible) the order of accuracy of the method. The choice of weights is given by the solution of a linear program. We investigate different approaches to choosing the weights by considering adding further constraints. We also provide some analysis of the properties of Runge-Kutta methods with perturbed weights. Numerical examples demonstrate the effectiveness of the approach, including application to both stiff and non-stiff problems.
Updated Parameter Estimates for GW190425 Using Astrophysical Arguments and Implications for the Electromagnetic Counterpart

description: The progenitor system of the compact binary merger GW190425 had a total mass of $3.4^{+0.3}_{-0.1}$ M$_\odot$ (90th-percentile confidence region) as measured from its gravitational wave signal. This mass is significantly different from the Milky Way (MW) population of binary neutron stars (BNSs) that are expected to merge in a Hubble time and from that of the first BNS merger, GW170817. Here we explore the expected electromagnetic signatures of such a system. We make several astrophysically motivated assumptions to further constrain the parameters of GW190425. By simply assuming that both components were NSs, we reduce the possible component masses significantly, finding $m_1 = 1.85^{+0.27}_{-0.19}$ M$_\odot$ and $m_2 = 1.47^{+0.16}_{-0.18}$ M$_\odot$. However if the GW190425 progenitor system was a NS-black hole merger, we find best-fitting parameters $m_1 = 2.19^{+0.21}_{-0.17}$ M$_\odot$ and $m_2 = 1.26^{+0.10}_{-0.08}$ M$_\odot$. For a well-motivated BNS system where the lighter NS has a mass similar to the mass of non-recycled NSs in MW BNS systems, we find $m_1 = 2.03^{+0.15}_{-0.14}$ M$_\odot$ and $m_2 = 1.35 \pm 0.09$ M$_\odot$, corresponding to only 7% mass uncertainties. For all scenarios, we expect a prompt collapse of the resulting remnant to a black hole. Examining detailed models with component masses similar to our best-fitting results, we find the electromagnetic counterpart to GW190425 is expected to be significantly redder and fainter than that of GW170817. We find that almost all reported observations used to search for an electromagnetic counterpart for GW190425 were too shallow to detect the expected counterpart. If the LIGO-Virgo Collaboration promptly provides the chirp mass, the astronomical community can adapt their observations to improve the likelihood of detecting a counterpart for similarly "high-mass" BNS systems.

description: We report the serendipitous discovery of a bright galaxy (Gal-A) observed as part of the ALMA Large Program to INvestigate [CII] at Early times (ALPINE). While this galaxy is detected both in line and continuum emission in ALMA Band 7, it is completely dark in UV/optical filters and only presents a marginal detection in the UltraVISTA Ks band. We discuss the nature of the observed ALMA line, i.e. whether the emission comes from [CII] at z~4.6, or from high-J CO transitions at z~2.2. In the first case we find a [CII]-to-FIR luminosity ratio of log(L_[CII]/L_FIR)=-2.5, consistent with the average value for local star-forming galaxies (SFGs); in the second case, instead, the source would lie outside of the empirical relations between L_CO and L_FIR found in the literature. At both redshifts, we derive the star-formation rate (SFR) from the ALMA continuum, and the stellar mass (M*) by using stellar population synthesis models as input for LePHARE spectral energy distribution (SED) fitting. Exploiting our results, we believe that Gal-A is a Main-Sequence (MS), dusty SFG at z=4.6 (i.e. [CII] emitter) with log(SFR/[M/yr])~1.4 and log(M*/M)~9.7. This work underlines the crucial role of the ALPINE survey in making a census of this class of objects, in order to unveil their contribution to the global star-formation rate density (SFRD) of the Universe at the end of the Reionisation epoch.

description: The Chinese aquaculture industry, which employs millions of farmers and provides low cost protein for consumers worldwide, is critically important to domestic economic growth and global food security. Central to the safety of aquaculture products are farmers, who are ultimately responsible for following good production practices. We assess how farmers’ value system is related to on-farm decision-making, with particular attention given to the overuse of antibiotics, a major problem in this industry. Primary data was gathered through farmer interviews in three aquaculture-producing provinces in Southern China. Using a best-worst scaling framework, we find that producers care most about attributes and practices that are directly related to their operation and are impartial to consumer preferences. Our results show that producers who value food safety the most are more likely to stop using antibiotics in their operations.

description: Farmers generally produce multiple crops while selectively adopting modern technologies in them to meet various needs. The present study jointly determines the factors influencing decisions to adopt modern technologies (i.e., HYV seeds and/or fertilisers) in multiple food crops (i.e., rice, yam and cassava) using a survey data of 400 farmers from Nigeria by applying a multivariate probit model. Model diagnostic reveals that the decisions to adopt modern technologies are significantly correlated, implying that univariate analysis of such decisions are biased, thereby, justifying use of multivariate approach. Results reveal that 68% of the farmers grew at least two food crops. Output price is an important determinant of HYV adoption. Farming experience is positively associated with HYV adoption whereas remoteness of extension services is negatively associated. HYV technology adoption is relatively higher for small farms whereas large farms use more fertilisers. Access to credit positively influences modern technology adoption. High profit is the main motive for adopting modern technologies. Policy recommendations include investments in extension infrastructure and credit services as well as measures to stabilise and/or improve output price efficiency, e.g., government procurement of outputs during harvest, grading and standardisation of food crops, reducing transaction costs of marketing and trade policies.

description: We analyze the anisotropy profile of the Milky Way's smooth, diffuse stellar halo using SDSS/SEGUE blue horizontal branch stars and SDSS/SEGUE and LAMOST K giants. These intrinsically luminous stars allow us to probe the halo to approximately 100 kpc from the Galactic center. Line-of-sight velocities, distances, metallicities, and proper motions are available for all stars via SDSS/SEGUE, LAMOST, and Gaia, and we use these data to construct a full 7D set consisting of positions, space motions, and metallicity. We remove substructure from our samples using integrals of motion based on the method of Xue et al. We find radially dominated kinematic profiles with nearly constant anisotropy within 20 kpc, beyond which the anisotropy profile gently declines although remains radially dominated to the furthest extents of our sample. Independent of star type or substructure removal, the anisotropy depends on metallicity, such that the orbits of the stars become less radial with decreasing metallicity. For $-1.7

description: This research examined the scientific exploration of human memory; it presented the stages of research in memory and the evolution of techniques to study it. The early studies were interested in evaluating memory capacity in order to construct memory span curves. It's asserted that the types of the presented information (concrete versus abstract …) influence the number of items recalled. It appears also that retention varies with interval between presentation and recall. Other works investigated the effect of sex variable on memory performance. There was a growth in memory research within the cognitive paradigm, which leads to the elaboration of models of human memory functioning.

description: The objective of this study was to list and analyse risk management tools applicable in managing farm risks. A literature search of several large literature databases was conducted. By using risk management-related keywords, a total of 13,559 articles discussing risk management were identified. Of these, 157 articles were selected for closer analysis applicable to dairy, cattle, pig or crop production. Both journal articles and book chapters in English were included. The articles were categorized based on the applied risk focus and type of risk management tools presented. In accordance with this, potential farm risk management tools were searched from the research studies associated with production, assets, economics and finance, human health and safety, and the environmental risks on farms. An important outcome of the study was a tool case for farm risk management stages, in which either the potential farm risk tools can each be used to address a single risk or the tools can be holistically applied. Farmers face multi-risk management demands, but comprehensive literature studies on multi-risk management tools on farms have been rare. Farm risk management tools and information provided to farmers are not at a sufficient level if we compare them to the current risks and social demands that farmers are facing. The possible farm risks should be clarified to farmers that they can identify them on farms. Furthermore, in order to integrate farm risk management tools, the links between the risks should be made visible among farm operations and farm production processes. Complexity and usability are future challenges in the further development of tools for managing farm risks. Applying the new farm risk tools in a sustainable manner requires farm managers to adopt new knowledge management techniques. Education programmes are needed to address the new skills that are required, and communication and co-operation between different research disciplines is also necessary.

Entsprechend finden sich in der Literatur viele nur schwer nachvollziehbare geochronologische Folgerungen. Sie können allerdings auch dann falsch sein, wenn sie sich auf Ergebnisse aus Datenbanken ohne ausreichende Angaben über den Ursprung des datierten Materials und die angewandten analytischen Techniken beziehen. Diese Arbeit führt in die Beurteilung und Handhabung numerischer Altersangaben ein. Mit ihr können elementare Rechnungen und einfache statistische Tests korrekt ausgeführt werden. Entsprechende Beispiele veranschaulichen den Weg dazu. Die mit der Visualisierung von numerischen Altern in Form von einfachen und Dispersions-Histogrammen verbundenen Probleme werden diskutiert.

description: A light Higgs portal scalar could be abundantly produced in the earth's atmosphere and decay in large-volume neutrino detectors. We point out that the Hyper-Kamiokande detector bears a strong discovery potential of probing such particles in an uncharted parameter space that is actively explored by intensity frontier experiments including rare kaon decays. The signal we propose to look for is electron-positron pair creation that manifests as a double-ring appearing from the same vertex. Most of these pairs originate from zenith angles above the Hyper-K detector's horizon. This search can be generalized to other new light states and is highly complementary to beam experiments.

description: The current study examined the effect of working memory capacity (WMC) on word recognition speed (WRS) in Arabic second grade readers. We start from the hypothesis that WRS performance depends on WMC. Two groups of good and poor readers were tested on measures of WMC and WRS.The results show that high working memory (WM) span readers are more rapid in word recognition (WR) than low WM span readers. We found also high correlations between WMC and WRS, which means that WMC can be a good predictor of word recognition ability in Arabic orthography.

description: The phenomenon of spontaneous scalarisation of charged black holes (BHs) has recently motivated studies of various Einstein-Maxwell-scalar models. Within these models, different classes of BH solutions are possible, depending on the non-minimal coupling function $f(ϕ)$, between the scalar field and the Maxwell invariant. Here we consider the class wherein both the (bald) electrovacuum Reissner-Nordström (RN) BH and new scalarised BHs co-exist, and the former are never unstable against scalar perturbations. In particular we examine the model, within this subclass, with a quartic coupling function: $f(Φ) = 1+αΦ^4$. The domain of existence of the scalarised BHs, for fixed $α$, is composed of two branches. The first branch (cold scalarised BHs) is continuously connected to the extremal RN BH. The second branch (hot scalarised BHs) connects to the first one at the minimum value of the charge to mass ratio and it includes overcharged BHs. We then assess the perturbative stability of the scalarised solutions, focusing on spherical perturbations. On the one hand, cold scalarised BHs are shown to be unstable by explicitly computing growing modes. The instability is quenched at both endpoints of the first branch. On the other hand, hot scalarised BHs are shown to be stable by using the S-deformation method. Thus, in the spherical sector this model possesses two stable BH local ground states (RN and hot scalarised). We point out that the branch structure of BHs in this model parallels the one of BHs in five dimensional vacuum gravity, with [Myer-Perry BHs, fat rings, thin rings] playing the role of [RN, cold scalarised, hot scalarised] BHs.

description: Im westlichen Geiseltal (mittleres Elbe-Saalegebiet, westlich von Merseburg) waren spätglaziale und holozäne Serien großflächig aufgeschlossen. Sie lagen auf der Niederterrasse und dem Löß der Weichselkaltzeit. Im wesentlichen handelte es sich um limnische und telmatische Sedimente. Sie zeigten eine Gliederung in fünf Sedimentzyklen mit zwei präböllingzeitlichen Intervallen (Müchelner Intervalle 1 und 2), mit Bölling, Alleröd und Holozän. Die Kaltphasen waren durch Beckenschluffe, die warmen Phasen durch Mudden und Torfe, seit dem Alleröd auch durch Charatravertinsande gekennzeichnet. Im Alleröd war die Laacher-See-Tephra eingelagert. In der Jüngeren Dryas-Zeit entstanden zum letzten Male Frostspaltennetze. Für Ältere Dryas-Zeit, Alleröd und Jüngere Dryas-Zeit wurde mit Hilfe der Pollenanalyse die Vegetationsgeschichte ermittelt. Alle Horizonte sind durch Molluskenfaunen dokumentiert, die in ihrer wechselnden Zusammensetzung den detaillierten Klimaablauf erkennen lassen. Zugleich liegt eine der bedeutendsten spätglazialen Molluskensukzessionen Mitteleuropas vor.

description: We present a new model atmosphere analysis of nine central stars of planetary nebulae. This study is based on a new generation of realistic stellar model atmospheres for hot stars; state-of-the-art, hydrodynamically consistent, spherically symmetric model atmospheres that have been shown to correctly reproduce the observed UV spectra of massive Population I O-type stars. The information provided by the wind features (terminal velocity, mass loss rate) permits to derive the physical size of each central star, from which we can derive the stellar luminosity, mass and distance, without having to assume a relation between stellar mass and luminosity taken from the theory of stellar structure and AGB and post-AGB evolution. The results of our analysis are quite surprising: we find severe departures from the generally accepted relation between post-AGB central star mass and luminosity.

description: Erstmalig wurden für den Saale-Elbe-Raum — als geologisch gut erschlossenes Untersuchungsgebiet Mitteleuropas — systematisch gesammelte Proben durch Radiokarbon datiert. Somit ist es möglich, das weichseiszeitliche Alter der intakten und gekappten Niederterrasse zu bestätigen sowie die stark differenzierte holozäne Flußdynamik chronostratigraphisch zu erfassen. Die in der nacheiszeitlichen Flußgeschichte innerhalb eines komplexen Wirkungsgefüges ablaufenden Sedimentationsprozesse wurden in bestimmten Einzugsgebieten durch mittelbare anthropogene Eingriffe bereits seit neolithischer Zeit stark beeinflußt. Dies zeigt sich vor allem im Beginn und Verlauf der Auelehmakkumulation. Durch die radiometrische Datierung subfossiler Hölzer aus holozänen Flußschottern konnte ebenfalls für den mitteldeutschen Raum die Verdrängung der Kiefer durch die Eiche aus den Flußtälern bereits für das Boreal (ältestes 14C-Datum 8790 ± 140 BP) festgestellt werden. Dies stimmt gut mit Befunden aus anderen Flußgebieten vor allem des südlichen Mitteleuropas überein.

description: We prove some inequalities for the spectral radius of positive operators on Banach function spaces. In particular, we show the following extension of Levinger's theorem. Let $K$ be a positive compact kernel operator on $L^2(X,μ)$ with the spectral radius $r(K)$. Then the function $ϕ$ defined by $ϕ(t) = r(t K + (1-t) K^*)$ is non-decreasing on $[0, {1/2}]$. We also prove that $\| A + B^* \| \ge 2 \cdot \sqrt{r(A B)}$ for any positive operators $A$ and $B$ on $L^2(X,μ)$.

description: The search for primordial gravitational waves in the Cosmic Microwave Background (CMB) will soon be limited by our ability to remove the lensing contamination to $B$-mode polarization. The often-used quadratic estimator for lensing is known to be suboptimal for surveys that are currently operating and will continue to become less and less efficient as instrumental noise decreases. While foregrounds can in principle be mitigated by observing in more frequency bands, progress in delensing hinges entirely on algorithmic advances. We demonstrate here a new inference method that solves this problem by sampling the exact Bayesian posterior of any desired cosmological parameters, of the gravitational lensing potential, and of the delensed CMB maps, given lensed temperature and polarization data. We validate the method using simulated CMB data with non-white noise and masking on up to 650\,deg$^2$ patches of sky. A unique strength of this approach is the ability to jointly estimate cosmological parameters which control both the primordial CMB and the lensing potential, which we demonstrate here for the first time by sampling both the tensor-to-scalar ratio, $r$, and the amplitude of the lensing potential, $A_ϕ$. The method allows us to perform the most precise check to-date of several important approximations underlying CMB-S4 $r$ forecasting, and we confirm these yield the correct expected uncertainty on $r$ to better than 10%.

The role of emotional processes in memory functioning.
Creators: name: El-Mir, Mohammed

Subjects: Applied Psychology

description: Emotion affects information processing. Many researchers were interested in the interaction between emotional and cognitive components. It was asserted that emotional processes affect cognitive functions, especially memory. So, we intend to figure out the correlations between emotion and information processing. So, we examined the emotional learning, in addition to the interactions between physiological structures that underlay emotion and memory. Furthermore, we delved the mood-state dependent memory, and the role of emotional intensity in recallability of events and informations. Thereafter, we discussed some works that explored the effect of emotion on some main memory structures such as working memory and long-term memory. Data from many studies showed that emotional system interven in information processing, and thereupon influences encoding, storage and retrieval of information. So, in order to understand better the functioning of memory, we should take into consideration the role of emotions in memory processes.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: It has been observed by numerous authors that a quantum system being entangled with another one limits its possible entanglement with a third system: this has been dubbed the "monogamous nature of entanglement". In this paper we present a simple identity which captures the trade-off between entanglement and classical correlation, which can be used to derive rigorous monogamy relations. We also prove various other trade-offs of a monogamy nature for other entanglement measures and secret and total correlation measures.

description: Napjainkban az üzleti termékek, szolgáltatások és a technológia területén jelentős mértékű innovációnak, átalakulásnak vagyunk szemtanúi. A változások gyorsasága miatt a hagyományos menedzsmentmodellek és tervezés gyakran nem elég a szervezetek számára piaci pozíciójuk megőrzéséhez, fejlesztéséhez. Mindezek ellenére a vezetői módszerek és vezetési stratégiák a 20. század eleje óta kevéssé változtak. Ahhoz, hogy valós, értékelhető és fenntartható üzleti eredményeket tudjunk a jelenlegi környezetben felmutatni, alapvető megújulásra van szükség a stratégiai tervezés, a szervezeti hatékonyság, a szervezeti változások irányítása, a vállalati értékrend és a dolgozói elkötelezettség javítása területén. A tanulmányban ezen újszerű törekvések megvalósításának néhány lehetséges módszerét kívánom bemutatni az aktuális nemzetközi és hazai szakirodalom elemzése alapján. ------------------------------- Today, we are witnessing a significant innovation in business products, services and technology. Due to the rapid pace of changes, the traditional business planning and management often is not longer enough to develop or maintain the market positions of the organisations. However, the traditional management methods just a little have changed since the early 20th century. To make a real and valuable business results can be presented in the current environment, there is a need for a fundamental renewal of strategic planning, organizational effectiveness, organizational change management, corporate values and employee engagement. In this study I intend to present some implementations of possible methods of those directives, based on the analysis of current international and Hungarian scientific literature.

description: Near-infrared magneto-optical spectroscopy of single-walled carbon nanotubes reveals two absorption peaks with an equal strength at high magnetic fields ($>$ 55 T). We show that the peak separation is determined by the Aharonov-Bohm phase due to the tube-threading magnetic flux, which breaks the time-reversal symmetry and lifts the valley degeneracy. This field-induced symmetry breaking thus overcomes the Coulomb-induced intervalley mixing which is predicted to make the lowest exciton state optically inactive (or ``dark'').

Quantum and Classical Message Identification via Quantum Channels

description: We discuss concepts of message identification in the sense of Ahlswede and Dueck via general quantum channels, extending investigations for classical channels, initial work for classical-quantum (cq) channels and "quantum fingerprinting". We show that the identification capacity of a discrete memoryless quantum channel for classical information can be larger than that for transmission; this is in contrast to all previously considered models, where it turns out to equal the common randomness capacity (equals transmission capacity in our case): in particular, for a noiseless qubit, we show the identification capacity to be 2, while transmission and common randomness capacity are 1. Then we turn to a natural concept of identification of quantum messages (i.e. a notion of "fingerprint" for quantum states). This is much closer to quantum information transmission than its classical counterpart (for one thing, the code length grows only exponentially, compared to double exponentially for classical identification). Indeed, we show how the problem exhibits a nice connection to visible quantum coding. Astonishingly, for the noiseless qubit channel this capacity turns out to be 2: in other words, one can compress two qubits into one and this is optimal. In general however, we conjecture quantum identification capacity to be different from classical identification capacity.
