description: Symmetry-protected zero modes in arrays of coupled optical elements have attracted considerable attention because they are expected to be robust against coupling disorders. In the Hermitian limit, zero modes are dark ones, i.e. the intensity in one sublattice vanishes; yet, in a non-Hermitian counterpart, zero modes can be bright and feature π/2 phase difference between sublattices. In this work, we report on the direct observation of a lasing zero mode in a non-Hermitian three coupled nanocavity array. We show efficient excitation for nearly equal pump power in the two extreme cavities. Furthermore, its efficiency can be dynamically controlled by pumping the center cavity. The realization of zero mode lasing in large arrays of coupled nanolasers has potential applications in laser-mode engineering and it opens up promising avenues in optical computing.

description: We argue that the existence of solitons in theories in which local symmetries are spontaneously broken requires spacetime to be enlarged by additional coordinates that are associated with large local transformations. In the context of gravity theories the usual coordinates of spacetime can be thought of arising in this way. E theory automatically contains such an enlarged spacetime. We propose that spacetime appears in an underlying theory when the local symmetries are spontaneously broken.

description: Bundles of filaments and motors are central to contractility in cells. The classic example is striated muscle, where actomyosin contractility is mediated by highly organized sarcomeres which act as fundamental contractile units. However, many contractile bundles in vivo and in vitro lack sarcomeric organization. Here we propose a model for how contractility can arise in actomyosin bundles without sarcomeric organization and validate its predictions with experiments on a reconstituted system. In the model, internal stresses in frustrated arrangements of motors with diverse velocities cause filaments to buckle, leading to overall shortening. We describe the onset of buckling in the presence of stochastic actin-myosin detachment and predict that buckling-induced contraction occurs in an intermediate range of motor densities. We then calculate the size of the "contractile units" associated with this process. Consistent with these results, our reconstituted actomyosin bundles contract at relatively high motor density, and we observe buckling at the predicted length scale.

description: Until the German reunification, public perception of the graves and cemeteries of Soviet prisoners of war has been rather marginal in both German states, in Europe and in the Soviet Union. Due to Stalinist repression, the names of Russian prisoners of war were intentionally not named; captivity remained a taboo issue in the soviet sphere of control until the collapse of the Soviet Union. During the Cold War, the cemeteries of Russian prisoners of war on the sites of former camps were reshaped and reinterpreted. It is only after the discussions that started in the mid-1990s regarding the participation of the Wehrmacht in war crimes that the graves and cemeteries of Russian prisoners of war are treated in a scholarly way. The article sketches this continuous process in an European context.

description: The composition and amount of interstellar dust within gamma-ray burst (GRB) host galaxies is of key importance when addressing selection effects in the GRB redshift distribution, and when studying the properties of their host galaxies. As well as the implications for GRB research, probing the dust within the high-z hosts of GRBs also contributes to our understanding of the conditions of the interstellar medium and star-formation in the distant Universe. Nevertheless, the physical properties of dust within GRB host galaxies continues to be a highly contended issue. In this paper we explore the mean extinction properties of dust within the host galaxies of a sample of 17 GRBs with total host galaxy visual extinction Av<1 (=0.4), covering a redshift range z=0.7-3.1. We find the average host extinction curve to have an ultraviolet slope comparable to that of the LMC, but with little evidence of a 2175Angs dust extinction feature as observed along Milky Way and LMC sightlines. We cannot at present rule out the presence of a 2175Angs feature, and both the standard SMC and LMC extinction curves also provide good fits to our data. However, we can reject an extinction curve that has a UV slope as flat as the mean Milky Way extinction curve, whilst also having a 2175Angs feature as prominent as seen in the mean Milky Way extinction curve. This is in contrast to the clear detection of a 2175Angs bump and the flatter extinction curves of some more heavily extinguished GRBs (Av>1), which may be indicative of there being a dependence between dust abundance and the wavelength dependence of dust extinction, as has been previously speculated.

description: Topological magnetic structures are promising candidates for resilient information storage. An elementary example are spin helices in one-dimensional easy-plane quantum magnets. To quantify their stability, we numerically implement the stochastic Schrödinger equation and time-dependent perturbation theory for spin chains with fluctuating local magnetic fields. We find two classes of quantum spin helices that can reach and even exceed ground-state stability: Spin-current-maximizing helices and, for fine-tuned boundary conditions, the recently discovered "phantom helices". Beyond that, we show that the helicity itself (left- or right-rotating) is even more stable. We explain these findings by separated helical sectors and connect them to topological sectors in continuous spin systems. The resulting helical protection mechanism is a promising phenomenon towards stabilizing helical quantum structures, e.g., in ultracold atoms and solid state systems. We also identify an - up to our knowledge - previously unknown new type of phantom helices.

description: Quantum phases of matter are characterized by the underlying correlations of the many-body system. Although this is typically captured by a local order parameter, it has been shown that a broad class of many-body systems possesses a hidden non-local order. In the case of bosonic Mott insulators, the ground state properties are governed by quantum fluctuations in the form of correlated particle-hole pairs that lead to the emergence of a non-local string order in one dimension. Using high-resolution imaging of low-dimensional quantum gases in an optical lattice, we directly detect these pairs with single-site and single-particle sensitivity and observe string order in the one-dimensional case.

description: Quasi-one-dimensional electron systems display intrinsic instability towards long-range ordered phases at sufficiently low temperatures. The superconducting orders are of particular interest as they can possess either singlet or triplet pairing symmetry and frequently compete with magnetism. Here we report on muon spin rotation and relaxation ($\mathrmμ$SR) study of Rb$_2$Mo$_3$As$_3$ characterised by one of the highest critical temperatures $T_{\rm c}=10.4\ \mathrm{K}$ among quasi-one-dimensional superconductors. The transverse-field $\mathrmμ$SR signal shows enhanced damping below $T_{\rm c}$ due to the formation of vortex lattice. Comparison of vortex lattice broadening against single gap $s-$, $p-$ and $d-$wave models shows the best agreement for the $s-$wave scenario but with the anomalously small superconducting gap, $Δ_0$, to $T_{\rm c}$ ratio of $2Δ_0/k_{\rm B}T_{\rm c}=2.74(1)$. The alternative nodal $p-$wave or $d-$wave scenarios with marginally worse goodness of fit would yield more realistic $2Δ_0/k_{\rm B}T_{\rm c}=3.50(2)$ and $2Δ_0/k_{\rm B}T_{\rm c}=4.08(1)$, respectively, and thus they cannot be ruled out when accounting for the superconducting state in Rb$_2$Mo$_3$As$_3$.

Distribution, abundance, and management implications of the grizzly bear and mountain caribou: in the Mountain Creek watershed of Glacier National Park, British Columbia

description: Bibliography: p. 147-154.
description: This study was initiated to provide Glacier National Park planners-managers with information on the distribution and abundance of grizzly bears and mountain caribou in the remote and little-visited Mountain Creek watershed. Observations and food habits studies suggested that grizzlies were distributed on avalanche slopes and in other forest openings in spring and early summer, and in berry producing habitat and alpine areas in late summer and autumn. A density of one grizzly to 13 miles was estimated for the Mountain Creek watershed. This figure was comparable to a density of one grizzly to 12 miles which has been determined for other watersheds of Glacier Park. Observations suggested that mountain caribou followed an annual "double migration," similar to that reported in Wells Gray Park. Caribou were observed at and above timberline in summer and winter, and in low elevation forest in autumn and spring. An estimated 25 mountain caribou inhabited the northwestern regions of Glacier Park. Their ranges included both provincial and national park adjacent lands. The observational data are interpreted in the light of comparable ecological and behavioural information available on these two species; and management directions are explored. Recommendations include the following: 1. Because the grizzly and caribou are wide-ranging, "wilderness-demanding" species (i.e., sensitive to human activities), provisions for their survival in Glacier Park will simultaneously accrue benefits to many other less-demanding members of the mountain ecosystem. The accordant use of the grizzly and caribou as ''wilderness indicator species" is a recommended management technique. 2. The boundaries of Glacier Park fail to include the total range requirements of the grizzly bear and mountain caribou. A protective corridor must be established adjacent to the park in order to provide for the perpetual maintenance of self-sustaining populations of grizzlies and caribou. In this protective unit, land-use policies can be implemented to control overkill, habitat alteration, and other disturbance. 3. In Glacier Park, certain critical ranges of grizzly bears and mountain caribou qualify as national park special ecological reserves. 4. The specific sensitivities of grizzlies and caribou to human visitation remain to be determined. Carrying capacities for visitors in wilderness areas should be calculated. 5. The grizzly bear requires additional management considerations because of potential conflicts with humans. Some areas in the Mountain Creek watershed were identified where visitors have a greater chance of meeting grizzlies. Also implicit in management is the elimination of artificial food sources both in and near the park.

Evolving utopias : an overview of three representative Punjabi works from 1890s, 1910s & 1930s
Creators: name: Shason, Jan-Paul
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines literary works from three critical periods in the history of colonial Panjab. The purpose of the examination is to understand the Panjabi society’s responses to the Raj and to trace the region’s social and intellectual history through these works. The first work, the 1898 ‘historical novel’ Sundari by Bhai Vir Singh, is from a time when the communities of the Panjab had begun to form collective responses to the new rulers and the Western education, religion and ideas they represented. It reflects the period of communal identity-building taking place by the three indigenous communities of Muslims, Hindus and Sikhs. From the 1910s, Ghadar Lahir di Kawita, the poetry of Ghadar (the political revolution contemplated by the mostly-Panjabi émigrés in the United States and Canada) just before the World War, reflects their response to the mis-treatment they receive in North America. Their desire and plans to regain personal and social honour is to vanquish their enemy, the British Raj. The world-view of this semi-literate community of the Panjabi diaspora is considerably different from the faith-based identity-building ideology of Sundari. From the 1930s, two nearly concurrent anthologies, Sawe Pattar and Kasumbharha, by the modern poet Mohan Singh are examined to trace the evolution of Punjabi into a modern language and of the region’s communities towards a more secular society. The three critical periods so examined through representative literary works show the evolution of Panjabi society’s aspirations from communalism to nationalism of political revolution to the building together of a secular society on “progressive” universalist grounds. These literary works idealize the aspirations of the society at three critical periods of history in differing responses to the challenges of those particular times by creating three different, and evolving, utopias.

description: Transition Path Theory (TPT) provides a rigorous statistical characterization of the ensemble of trajectories connecting directly, i.e., without detours, two disconnected (sets of) states in a Markov chain, a stochastic process that undergoes transitions from one state to another with probability depending on the state attained in the previous step. Markov chains can be constructed using trajectory data via counting of transitions between cells covering the domain spanned by trajectories. With sparse trajectory data, the use of regular cells is observed to result in unstable estimates of the total duration of transition paths. Using Voronoi cells resulting from k-means clustering of the trajectory data, we obtain stable estimates of this TPT statistic, which is generalized to frame the remaining duration of transition paths, a new TPT statistic suitable for investigating connectivity.

description: We present results of broad band photometric reverberation mapping (RM) to measure the radius of the broad line region, and subsequently the black hole mass (M$_{\rm BH}$), in the nearby, low luminosity active galactic nuclei (AGN) NGC 4395. Using the Wise Observatory's 1m telescope equipped with the SDSS g$'$, r$'$ and i$'$ broad band filters, we monitored NGC 4395 for 9 consecutive nights and obtained 3 light curves each with over 250 data points. The g$'$ and r$'$ bands include time variable contributions from H$β$ and H$α$ (respectively) plus continuum. The i$'$ band is free of broad lines and covers exclusively continuum. We show that by looking for a peak in the difference between the cross-correlation and the auto-correlation functions for all combinations of filters, we can get a reliable estimate of the time lag necessary to compute M$_{\rm BH}$. We measure the time lag for H$α$ to be $3.6 \pm 0.8 $ hours, comparable to previous studies using the line resolved spectroscopic RM method. We argue that this lag implies a black hole mass of M$_{\rm BH} = (4.9 \pm 2.6) \times 10^{4}$ \Msun .

description: We investigate a many-body wave function for particles on a cylinder known as Laughlin's function. It is the power of a Vandermonde determinant times a Gaussian. Our main result is: in a many-particle limit, at fixed radius, all correlation functions have a unique limit, and the limit state has a non-trivial period in the axial direction. The result holds regardless how large the radius is, for fermions as well as bosons. In addition, we explain how the algebraic structure used in proofs relates to a ground state perturbation series and to quasi-state decompositions, and we show that the monomer-dimer function introduced in an earlier work is an exact, zero energy, ground state of a suitable finite range Hamiltonian; this is interesting because of formal analogies with some quantum spin chains.

Rotavirus infection is of public health concern because it is highly contagious and yet can be prevented. Diarrhoea ranks third among the common causes of mortality in Zambia among under-fives which accounts for about 9%. Statistics obtained at Ndola District Health Management Office revealed that despite high coverage of rotavirus vaccine, diarrhoea incidence had risen over the years from 2011 to 2015 by 32.9/1000. When the rotavirus enters the body through ingestion, it infects the stomach and intestinal tract (gastroenteritis) damaging the cells of the small intestine making it difficult for the absorption of water and nutrients by the body Currently stool is not routinely tested for rotavirus infection, making it difficult to determine its incidence and effectiveness of rotavirus vaccine (RotarixTM), an intervention that was put in place on 27th November 2013 to mitigate diarrhoea disease. The objective of this study is to determine the incidence of rotavirus infection among under-fives attending health centres in selected communities of Ndola. Purposive sampling was used to select 380 under-fives aged 3 months - 36 months who presented at health facilities with diarrhoea, vomiting and fever. Stool specimen was tested for rotavirus infection using Combi-Strip Rapid Diagnostic Test. The study was conducted at the specified period in time from 1st March 2017 to 28th September 2017 to determine relationships and associations among suspected variables using cross-sectional analytic community-based study design. Statistical Package for Social Science software was used for data analysis. Tests used included Pearson’s Chi-square and logistic regression. Results have revealed 11% incidence rate of rotavirus infection and significant statistical association among severity categories of rotavirus infection with the uptake of rotavirus vaccine (p ≤ 0.001). Children who took two recommended doses of the vaccine 185 (59.5%) were more likely to have a mild category (< 7 scores) of rotavirus infection. In conclusion, results indicate that rotavirus vaccine reduces the incidence and if a child has diarrhoea it is less severe which yields good outcomes.

description: We provide the exact analytic solution of the stochastic Schrödinger equation describing an harmonic oscillator interacting with a non-Markovian and dissipative environment. This result represents an arrival point in the study of non-Markovian dynamics via stochastic differential equations. It is also one of the few exactly solvable models, for infinite dimensional systems. We compute the Green's function; in the case of a free particle, and with an exponentially correlated noise, we discuss the evolution of Gaussian wave functions.

description: Jerusalem sites representing the Passion of Christ shape the landscape of Catholic Central Europe. Several architectural evocations of Jerusalem commemorate contemporary agony, namely local victims of the World Wars. Placing soldiers within the narrative of Christ’s Way of the Cross serves a political-ideological agenda as well as a psychological need of local populations, giving meaning to the soldiers' deathsand placing them in a salvific context. In this paper two case studies, the Calvary of Klagenfurt and the Way of the Cross in Syców (Groß-Wartenberg), are presented to highlight this phenomenon.

description: We assume that the sample height measured using AFM is reduced due to contact deformation. The Herz contact theory is applied for the quantitative description. General numerical solution is found. Analytical approximations for specific contact geometry are derived for the case of cylindrical sample. It is found that theoretical description are consistent with experimental data. The developed approach has allowed to determine elastic parameters of individual microobjects adsorbed on a surface of solid substrate.

Year: 2017

description: This article discusses the ways in which society has dealt with and deals with the graves of soldiers who were sentenced to death by military jurisdiction during the Nazi regime. It pleads for a more in depth consideration of this group of victims, and suggests appropriate possibilities for remembrance. After a survey of the interment regulations of the Third Reich and the relocation of such graves in the 1950s and 1960s, two examples are given which try to make these victims visible in Germany's commemorative culture. Finally, the potential of war cemeteries for remembering and historical learning is analyzed as well as the benefits that may derive from the inclusion of these victims of military jurisdiction into contemporary commemorative culture.

0231 The Great Ball Game Hall of Prague Castle: Its Appearance and Function in the Context of Habsburg Renaissance Ballcourts
Creators: name: Dobalová, Sylva
Publisher: name: RIHA Journal
Year: 2019

description: The Great Ball Game Hall of Prague Castle, dating from the years 1567–1569 and built for Emperor Maximilian II, presents an exceptional architectural realization. Apart from the representative appearance of the Great Ball Game Hall also its unusual scale is singular: It is roughly twice as long as was the custom and as was recommended by the Trattato del giuoco della palla by Antonio Scaino (Ferrara 1555). The dimensions of the building are linked to the question of how the Great Ball Game Hall was actually used. Archival sources from the time of the reign of Emperor Rudolf II indicate that it was used probably for the pallone game and not for the game of tennis. From the framework given by the historiography of Renaissance sports and recreation evolves the hypothesis that also covered buildings for the pallone game existed – contrary to the dominant opinion that the game was played exclusively outdoors.

description: We present the overview and current results of an ongoing optical/NIR monitoring of seven GLQs with the 2-m Liverpool Robotic Telescope. The photometric data over the first seven years of this programme (2005-2011) are leading to high-quality light curves, which in turn are being used as key tools for different standard and novel studies. While brightness records of non-lensed distant quasars may contain unrecognized extrinsic variations, one can disentangle intrinsic from extrinsic signal in certain GLQs. Thus, some GLQs in our sample allow us to assess their extrinsic and intrinsic variations, as well as to discuss the origin of both kinds of fluctuations. We also demonstrate the usefulness of GLQ time-domain data to obtain successful reverberation maps of inner regions of accretion disks around distant supermassive black holes, and to estimate redshifts of distant lensing galaxies.

description: For families of Hamiltonians defined by parts that are local, the most general definition of a symmetry algebra is the commutant algebra, i.e., the algebra of operators that commute with each local part. Thinking about symmetry algebras as commutant algebras allows for the treatment of conventional symmetries and unconventional symmetries (e.g., those responsible for weak ergodicity breaking phenomena) on equal algebraic footing. In this work, we discuss two methods for numerically constructing this commutant algebra starting from a family of Hamiltonians. First, we use the equivalence of this problem to that of simultaneous block-diagonalization of a given set of local operators, and discuss a probabilistic method that has been found to work with probability 1 for both Abelian and non-Abelian symmetries or commutant algebras. Second, we map this problem onto the problem of determining frustration-free ground states of certain Hamiltonians, and we use ideas from tensor network algorithms to efficiently solve this problem in one dimension. These numerical methods are useful in detecting standard and non-standard conserved quantities in families of Hamiltonians, which includes examples of regular symmetries, Hilbert space fragmentation, and quantum many-body scars, and we show many such examples. In addition, they are necessary for verifying several conjectures on the structure of the commutant algebras in these cases, which we have put forward in earlier works. Finally, we also discuss similar methods for the inverse problem of determining local operators with a given symmetry or commutant algebra, which connects to existing methods in the literature. A special case of this construction reduces to well-known ``Eigenstate to Hamiltonian" methods for constructing Hermitian local operators that have a given state as an eigenstate.

description: We study tetrahedron maps, which are set-theoretical solutions to the Zamolodchikov tetrahedron equation, and their matrix Lax representations defined by the local Yang--Baxter equation. Sergeev [S.M. Sergeev 1998 Lett. Math. Phys. 45, 113--119] presented classification results on three-dimensional tetrahedron maps obtained from the local Yang--Baxter equation for a certain class of matrix-functions in the situation when the equation possesses a unique solution which determines a tetrahedron map. In this paper, using correspondences arising from the local Yang--Baxter equation for some simple $2\times 2$ matrix-functions, we show that there are (non-unique) solutions to the local Yang--Baxter equation which define tetrahedron maps that do not belong to the Sergeev list; this paves the way for a new, wider classification of tetrahedron maps. We present invariants for the derived tetrahedron maps and prove Liouville integrability for some of them. Furthermore, using the approach of solving correspondences arising from the local Yang--Baxter equation, we obtain several new birational tetrahedron maps, including maps with matrix Lax representations on arbitrary groups, a $9$-dimensional map associated with a Darboux transformation for the derivative nonlinear Schrödinger (NLS) equation, and a $9$-dimensional generalisation of the $3$-dimensional Hirota map.

0138 George Kubler Shifting South: Architecture History Following Geopolitics
Creators: name: Santos, Eliana Sousa
Publisher: name: RIHA Journal
Year: 2016

description: This essay aims to present the shifting relations between North America and the South - South America and the South of Europe - through the work of the historian George Kubler. At the beginning of his career as a scholar, Kubler was invited by the Department of State to participate in a conference on inter-American relations. Later, with the positioning of the United States in World War II, the transatlantic relationship between the US and Europe became more prominent. Kubler’s research interests followed this change: His research shift from South America to peripheral Southern Europe reflects an availability of funding given his country's geopolitical interests. So far, artists and other scholars have praised Kubler’s vast work regarding the art and architecture of different 'Souths' mainly as a sign of 'nonalignment' and of his attention to the condition of peripheral countries.

0140 The Greek Pavilion in the Exposition Internationale des Arts et Techniques dans la Vie Moderne
Creators: name: Kosmadaki, Polina
Publisher: name: RIHA Journal
Year: 2016

description: This paper discusses the impact of the ideological trends of the Exposition Internationale des Arts et Techniques dans la Vie Moderne which took place in Paris, in 1937, on Greece's national participation in the exhibition. The modern artworks it showcased will serve as a case study to investigate notions of regionalism. The paper considers the conception and realisation of the Greek pavilion in association with the Exposition's affirmed focus on regionalism and examines the relation between nationalism and regionalism at that time. The Greek pavilion and its artists will also be discussed in regard to the local ideologies they expressed or contributed to generate. The aim of this paper is to highlight how, on the occasion of the 1937 exhibition, the Greek quest for a new form of national art – an authentic expression of "Greekness" able to overturn the European perception, which identified the "Greek" with the "classical" – converged or diverged from European regionalist and nationalist discourses as expressed by the exhibition's commissioner, as well as to draw attention to the paradoxes of this connection.
