Utilizzando i telescopi Ngts, un team di ricercatori ha progettato un nuovo metodo per individuare i pianeti con un periodo di rotazione attorno alla propria stella molto lungo, rilevando nuovamente il pianeta Ngts-11b – scoperto da Tess nel 2018 – tra centinaia di mondi perduti. La riscoperta di questi pianeti potrebbe spianare la strada alla ricerca di mondi nella zona abitabile di lontani sistemi planetari. Tutti i dettagli su ApJ Letters
Adiabatic Splitting, Transport, and Self-Trapping of a Bose-Einstein Condensate in a Double-Well Potential

description: We show that the adiabatic dynamics of a Bose-Einstein condensate (BEC) in a double well potential can be described in terms of a dark variable resulting from the combination of the population imbalance and the spatial atomic coherence between the two wells. By means of this dark variable, we extend, to the non-linear matter wave case, the recent proposal by Vitanov and Shore [Phys. Rev. A 73, 053402 (2006)] on adiabatic passage techniques to coherently control the population of two internal levels of an atom/molecule. We investigate the conditions to adiabatically split or transport a BEC as well as to prepare an adiabatic self trapping state by the optimal delayed temporal variation of the tunneling rate via either the energy bias between the two wells or the BEC non-linearity. The emergence of non-linear eigenstates and unstable stationary solutions of the system as well as their role in the breaking down of the adiabatic dynamics is investigated in detail.

Il Very Large Telescope dell'Eso ha catturato la prima immagine in assoluto di una giovane stella simile al Sole accompagnata da due esopianeti giganti. Le immagini di sistemi con più esopianeti sono estremamente rare e – fino ad ora – gli astronomi non avevano mai osservato direttamente più di un pianeta in orbita intorno a una stella simile alla nostra. Le osservazioni possono aiutare gli astronomi a capire come si sono formati e come si sono evoluti i pianeti intorno al Sole
Identifying Supermassive Black Hole Binaries with Broad Emission Line Diagnosis

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: Double-peaked broad emission lines in Active Galactic Nuclei (AGNs) may indicate the existence of a bound supermassive black hole (SMBH) binary where two distinct broad line regions (BLRs) contribute together to the line profile. An alternative interpretation is a disk emitter origin for the double-peaked line profile. Using simple BLR models, we calculate the expected broad line profile for a SMBH binary at different separations. Under reasonable assumptions that both BLRs are illuminated by the two active SMBHs and that the ionizing flux at the BLR location is roughly constant, we confirm the emergence of double-peaked features and radial velocity drifts of the two peaks due to the binary orbital motion. However, such a clear double-peaked feature only arises in a particular stage of the binary evolution when the two BHs are close enough such that the line-of-sight orbital velocity difference is larger than the FWHM of the individual broad components, while the two BLRs are still mostly distinct. Prior to this stage, the velocity splitting due to the orbit motion of the binary is too small to separate the emission from the two BLRs, leading to asymmetric broad line profiles in general. When the two BHs are even closer such that the two BLRs can no longer be distinct, the line profile becomes more complex and the splitting of the peaks does not correspond to the orbital motion of the binary. In this regime there are no coherent radial velocity drifts in the peaks with time. Asymmetric line profiles are probably a far more common signature of binary SMBHs than are double-peaked profiles. We discuss the temporal variations of the broad line profile for binary SMBHs and highlight the different behaviors of reverberation mapping in the binary and disk emitter cases, which may serve as a feasible tool to disentangle these two scenarios.

description: In a flat universe dominated by dark energy, the Integrated Sachs-Wolfe (ISW) effect can be detected as a large-angle cross-correlation between the CMB and a tracer of large scale structure. We investigate whether the inconclusive ISW signal derived from 2MASS galaxy maps can be improved upon by including photometric redshifts for the 2MASS galaxies. These redshifts are derived by matching the 2MASS data with optical catalogues generated from SuperCOSMOS scans of major photographic sky surveys. We find no significant ISW signal in this analysis; an ISW effect of the form expected in a LambdaCDM universe is only weakly preferred over no correlation, with a likelihood ratio of 1.5:1. We consider ISW detection prospects for future large scale structure surveys with fainter magnitude limits and greater survey depth; even with the best possible data, the ISW cross-correlation signal would be expected to evade detection in >~ 10% of cases.

Canada and League sanctions, 1919-1936
Creators: name: Saywell, John Tupper
Publisher: name: University of British Columbia
Year: 2012

description: In 1919 Canada became a member of the League of Nations. In so doing she accepted the obligation to support the maintenance of peace by the collective measures defined in the League Covenant. This included the preservation of the territorial integrity and political independence of every League member against external aggression by the application of financial, economic and, if necessary, military measures. These sanctions were outlined in Article 10 and Article 16 of the Covenant. Canada accepted these obligations with mixed feelings. Some elements in the Dominion opposed from the beginning the assumption of any external obligations. Others considered the enhancement of the nation's international status as outweighing the burden of sanctions. Very few were of the opinion that it was to Canada's advantage to play an active role in the League and do all in her power to preserve peace by joining in collective measures against an aggressor. As time passed both government policy and public opinion became more hostile towards Canadian commitments to the League. From the Paris Peace Conference of 1919 to the Fourth Assembly in 1922 Conservatives and Liberals alike attempted to remove or dilute the irksome obligations. Canada initiated an attack on Article 10 and supported the movement for the weakening of Article 16. The effect on Canada of the abstention of the United States was immediate and profound. The period between the wars was marked by an ever increasing intimacy in the relations between the two states. Every Canadian government closely watched the prevailing attitude in the United States and supported any action by the League which might facilitate the entry of the United States. In addition, Canada's position on the continent of North America was used as an excuse for a negative role in the League. The government of Canada refused to accept the draft treaties or the Geneva Protocol for it was believed that these schemes increased the obligation to participate in collective measures. The Pact of Paris, on the other hand, was accepted with some enthusiasm. It contained no specific obligations and was endorsed by the United States. The economic depression, the failure of collective security and the breakdown of the League of Nations, and the rise of armed dictatorships increased the isolationist sentiment in Canada. By the end of 1935 the great majority of Canadians were inclined to favor a North American policy of aloofness towards Europe and the League. Their natural sympathies lay with the isolationism of the United States. Throughout the period from 1919 to 1926, from the birth to the death of the League of Nations, Canada's policy towards League sanctions was one of negation. This policy was subscribed to by every Canadian government and was supported by the Canadian people. This paper surveys the more prominent features and outstanding incidents of Canadian policy and opinion with regard to League sanctions.

description: Let $k\ge 0,a\ge 1$ and $b\ge 0$ be integers. We define the arithmetic function $g_{k,a,b}$ for any positive integer $n$ by $g_{k,a,b}(n):=\frac{(b+na)(b+(n+1)a)...(b+(n+k)a)} {{\rm lcm}(b+na,b+(n+1)a,...,b+(n+k)a)}.$ Letting $a=1$ and $b=0$, then $g_{k,a,b}$ becomes the arithmetic function introduced previously by Farhi. Farhi proved that $g_{k,1,0}$ is periodic and that $k!$ is a period. Hong and Yang improved Farhi's period $k!$ to ${\rm lcm}(1,2,...,k)$ and conjectured that $\frac{{\rm lcm}(1,2,...,k,k+1)}{k+1}$ divides the smallest period of $g_{k,1,0}$. Recently, Farhi and Kane proved this conjecture and determined the smallest period of $g_{k,1,0}$. For the general integers $a\ge 1$ and $b\ge 0$, it is natural to ask the interesting question: Is $g_{k,a,b}$ periodic? If so, then what is the smallest period of $g_{k,a,b}$? We first show that the arithmetic function $g_{k,a,b}$ is periodic. Subsequently, we provide detailed $p$-adic analysis of the periodic function $g_{k,a,b}$. Finally, we determine the smallest period of $g_{k,a,b}$. Our result extends the Farhi-Kane theorem from the set of positive integers to general arithmetic progressions.

description: Have you ever asked yourself what the basis of your search engine autocompletions is? For example, when it was suggested that you search for what it feels like to have heartburn, whilst your intended search seemed to have nothing to do with it at all. There is not yet a standard for explaining such automated decisions. Moreover, today's explainable AI (XAI) frameworks focus strongly on individual interests, while a societal perspective falls short. This article will give an introduction to communication in XAI and introduce the figure of the public advocate as a possibility to include collective interests in XAI frameworks. The article is based on the thoughts of Dr. Theresa Züger, Dr. Hadi Asghari, Johannes Baeck and Judith Faßbender during the XAI Clinic in Autumn 2021.

description: We suggest that the solution to the cosmological vacuum energy puzzle is linked to the infrared sector of the effective theory of gravity interacting with standard model fields, with QCD fields specifically. We work in the framework of low energy quantum gravity as an effective field theory. In particular, we compute the vacuum energy in terms of QCD parameters and the Hubble constant $H$ such that the vacuum energy is $ε_{vac} \sim H \cdot m_q\la\bar{q}q\ra /m_{η'} \sim (3.6\cdot 10^{-3} \text{eV})^4$, which is amazingly close to the observed value today. The QCD ghost (responsible for the solution of the $U(1)_A$ problem) plays a crucial rôle in the computation of the vacuum energy, because the ghost's properties at very large but finite distances slightly deviate (as $\sim H / \Lqcd $) from their infinite volume Minkowski values. Another important prediction of this framework states that the vacuum energy owes its existence to the asymmetry of the cosmos. Indeed, this effect is a direct consequence of the embedding of our Universe on a non-trivial manifold such as a torus with (slightly) different linear sizes. Such a violation of cosmological isotropy is apparently indeed supported by WMAP, and will be confirmed (or ruled out) by future PLANCK data.

Investigation of nonlocal information as condition for violations of Bell inequality and information causality

description: On the basis of local realism theory, nonlocal information is necessary for violation of Bell's inequality. From a theoretical point of view, nonlocal information is essentially the mutual information on distant outcome and measurement setting. In this work we prove that if the measurement is free and unbiased, the mutual information about the distant outcome and setting is both necessary for the violation of Bell's inequality in the case with unbiased marginal probabilities. In the case with biased marginal probabilities, we point out that the mutual information about distant outcome cease to be necessary for violation of Bell's inequality, while the mutual information about distant measurement settings is still required. We also prove that the mutual information about distant measurement settings must be contained in the transmitted messages due to the freedom of measurement choices. Finally we point out that the mutual information about both distant outcome and measurement settings are necessary for a violation of information causality.

description: We investigated the entropy bounds of the three types of statistics: para-Bose, para-Fermi and infinite statistics. We showed that the entropy bounds of the conventional Bose, Fermi statistics and their generalizations to parastatistics obey the $A^{3/4}$ law, while the entropy bound of infinite statistics obeys the area law. This suggests a close relationship between infinite statistics and quantum gravity.

description: Various versions of the definition of nonclassical symmetries existing in the literature are analyzed. Comparing properties of Lie and nonclassical symmetries leads to the conclusion that in fact a nonclassical symmetry is not a symmetry in the usual sense. Hence the term "reduction operator" is suggested instead of the name "operator of nonclassical symmetries". It is shown that in contrast to the case of single partial differential equations a satisfactory definition of nonclassical symmetries for systems of such equations has not been proposed up to now. Moreover, the cardinality of essential nonclassical symmetries is discussed, taking into account equivalence relations on the entire set of nonclassical symmetries.

A study of the ecology of beaver in central British Columbia
Creators: name: Cottle, Walter Henry
Publisher: name: University of British Columbia
Year: 2012

description: Prior to the present work no studies had been made of the ecology of beaver in the glaciated areas of the intermountain plateau of British Columbia, Field studies for this study were carried out in the forested areas of the Cariboo and Chilcotln Districts of the Province during the summers of 1949 and 1950. In 1950 these studies were limited to the trapllne of Mr. E. Collier, Meldrum Creek, B. C. Two pair of live beaver were released on Collier's trapline by the British Columbia Game Department in 1942 and by 1950 these had increased to twenty-one colonies in addition to animals harvested in 1950. Studies were made of some conditions affecting this increase. Examination of areas inhabited by beaver showed that although water is apparently important to the animals as protection from the climate and for escape from certain enemies, it also provides the means whereby the beaver store winter food. Records were kept of the water levels of nine beaver ponds and these showed that beaver dams act as a regulating mechanism and tend to prolong the flow of water in Meldrum Creek. A number of techniques were used to determine the food habits of beaver on the study area and these revealed that although beaver consume mostly the bark of aspen and willow, a number of other foods were taken. A study of the conditions affecting the rate of growth and reproduction of aspen was made. Tallies were made of the stumps of the aspen trees cut in 1949 by beaver of twelve colonies and of trees in sample areas in stands available to these colonies. Such tallies showed that beaver cut all sizes of aspen without preference and that the mean weight of barks and twigs made available by cutting was approximately thirty-seven hundred pounds per colony. Studies of the rate of cutting by beaver In relation to the availability and to the rate of reproduction of aspen demonstrated that beaver on the study area occupy two somewhat distinct habitats, namely lakes and streams. Populations on lakes tend to be stable as there is sufficient reproduction in the large stands available to maintain the stand during use by beaver. Populations on creeks eat out their food supplies and are thus forced to emigrate. By developing the aquatic habitat beaver were observed to have increased the habitat suitable to a number of other species of vertebrates.

Un team di ricercatori guidato dall’astrofisico romano Claudio Ricci, oggi in Cile all'Università Diego Portales di Santiago, ha osservato per la prima volta la corona di un buco nero supermassiccio scomparire nell’arco di appena 40 giorni, per poi riapparire nei due anni successivi. A innescare la drastica trasformazione potrebbe essere stata la collisione con una stella

description: We study the detectability of the gravitational waves (GWs) from the Q-ball formation associated with the Affleck-Dine (AD) mechanism, taking into account both of the dilution effect due to Q-ball domination and of finite temperature effects. The AD mechanism predicts the formation of non-topological solitons, Q-balls, from which GWs are generated. Q-balls with large conserved charge $Q$ can produce a large amount of GWs. On the other hand, the decay rate of such Q-balls is so small that they may dominate the energy density of the universe, which implies that GWs are significantly diluted and that their frequencies are redshifted during Q-ball dominated era. Thus, the detectability of the GWs associated with the formation of Q-balls is determined by these two competing effects. We find that there is a finite but small parameter region where such GWs may be detected by future detectors such as DECIGO or BBO, only in the case when the thermal logarithmic potential dominates the potential of the AD field. Otherwise GWs from Q-balls would not be detectable even by these futuristic detectors: $Ω_{\rm GW}^0<10^{-21}$. Unfortunately, for such parameter region the present baryon asymmetry of the universe can hardly be explained unless one fine-tunes A-terms in the potential. However the detection of such a GW background may give us an information about the early universe, for example, it may suggest that the flat directions with $B-L=0$ are favored.
