description: An efficient multi-mode quantum memory is a crucial resource for long-distance quantum communication based on quantum repeaters. We propose a quantum memory based on spectral shaping of an inhomogeneously broadened optical transition into an atomic frequency comb (AFC). The spectral width of the AFC allows efficient storage of multiple temporal modes, without the need to increase the absorption depth of the storage material, in contrast to previously known quantum memories. Efficient readout is possible thanks to rephasing of the atomic dipoles due to the AFC structure. Long-time storage and on-demand readout is achieved by use of spin-states in a lambda-type configuration. We show that an AFC quantum memory realized in solids doped with rare-earth-metal ions could store hundreds of modes or more with close to unit efficiency, for material parameters achievable today.

urn:lsid:zoobank.org:act: 9743A462-BB55-45D0-9BA6-1C1AB43DE9DC
Fig. 10; Table 6
Etymology
After the Latin nomen ‘ padus ’, meaning ‘twine, yarn’ and referring to the conch shape like a yarn reel.
Type material
Holotype ALGERIA • Gourara, Sebkha de Timimoun 14.5 km west-southwest of Timimoun; “ Dalle à Merocanites ” (Tournaisian-Viséan boundary interval); illustrated in Fig. 10; MB.C.30383.
Diagnosis
Species of Vestinautilus with strongly depressed, rounded-trapezoidal whorl profile (ww/wh ~ 2.10), venter broadly arched, ventrolateral shoulder defined by an angular margin produced by a broad ridge. A second, sharper ridge is located on the umbilical wall near the ventrolateral shoulder. Whorls weakly embracing, coiling very high (WER ~ 2.55). Ornament with delicate growth lines.
Description
Holotype MB.C.30383 is a rather well-preserved specimen with a diameter of 34 mm (Fig. 10). It is a subevolute conch (ww/dm = 0.90; uw/dm = 0.33) with a very high coiling rate (WER = 2.57). The diameter of the umbilical window is about 5 mm. The whorl profile is strongly depressed (ww/wh = 2.11) and rounded-trapezoidal in outline with a broadly arched venter. The flanks and the venter are fused together; they are separated from the convex umbilical wall by two longitudinal ridges, which are separated by a shallow longitudinal groove. While the outer of the two ridges is subangular in cross section, the inner one is sharp and probably raised only by shell material. The shell ornament consists of delicate growth lines, which are reinforced on the inner longitudinal ridge.
Remarks
Vestinautilus padus sp. nov. belongs to the species of the genus that possess a very broad whorl profile (ww/wh> 2.00) and an ornament with only a few spiral ridges. In this respect, V. cariniformis (Sowerby, 1825), V. paucicarinatus (Foord, 1891), V. pinguis (de Koninck, 1844) and V. semiplicatus are similar, but these four species have a concave venter at least in some phases in ontogeny (Sowerby 1825; de Koninck 1844; Foord 1891, 1900). Subvestinautilus crassimarginatus (Foord, 1900) and S. crateriformis (Foord, 1900) have a convex venter in all stages (Foord 1900), but they do not have the spiral ridges that are characteristic for V. padus sp. nov.

The colonies are organised in a dense web of thread-like stolons, mixed with sponges and settled on rocks. The white opaque zooids are 6mm in length with a red line encircling the base of each siphon (Fig. 12A). The lobes of the siphons have a white tip. This aspect is characteristic of the species. The gonads are not developed here but the anatomy is that described in Monniot & Monniot (2001). The geographic distribution of this species comprises Indonesia, the Philippines and the south western Indian Ocean at low depths.

description: We discuss $Z$ mediated flavour changing neutral currents within a model where the hierarchical quark and lepton masses are explained via a fourth vector-like family, together with a scalar sector consisting of two Higgs doublets augmented by a gauge singlet scalar field that spontaneously breaks an extra global $U(1)^{\prime}$ symmetry. The $Z$ mediated flavor violating interactions arise from the mixings between the SM fermions and the vector-like fermions, where the mixing is discussed in an analytic approximation and also exactly numerically. We first discuss charged lepton flavor violating (CLFV) $τ\rightarrow μγ, τ\rightarrow 3μ$ and $Z \rightarrow μτ$ decays and find that they cannot significantly constrain the masses of charged vector-like leptons. However, the $790 \text{GeV}$ mass bound arising from collider searches on vector-like lepton doublets can set further constraints on the model parameter space. We also consider rare $t \rightarrow c Z$ decays as well as unitarity violation in the CKM mixing in order to constrain the quark sector of the model under consideration.

description: Machine learning for materials discovery has largely focused on predicting an individual scalar rather than multiple related properties, where spectral properties are an important example. Fundamental spectral properties include the phonon density of states (phDOS) and the electronic density of states (eDOS), which individually or collectively are the origins of a breadth of materials observables and functions. Building upon the success of graph attention networks for encoding crystalline materials, we introduce a probabilistic embedding generator specifically tailored to the prediction of spectral properties. Coupled with supervised contrastive learning, our materials-to-spectrum (Mat2Spec) model outperforms state-of-the-art methods for predicting ab initio phDOS and eDOS for crystalline materials. We demonstrate Mat2Spec's ability to identify eDOS gaps below the Fermi energy, validating predictions with ab initio calculations and thereby discovering candidate thermoelectrics and transparent conductors. Mat2Spec is an exemplar framework for predicting spectral properties of materials via strategically incorporated machine learning techniques.

description: We study the condensation of localized closed string tachyons on AdS orbifolds both from the bulk and boundary theory viewpoints. We first extend the known results for AdS_5/Z_k to AdS_3/Z_k case, and we proposed that the AdS_3/Z_k decays into AdS_3/Z_k' with k' < k. From the bulk viewpoint, we obtain a time-dependent gravity solution describing the decay of AdS orbifold numerically. From the dual gauge theory viewpoint, we calculated the Casimir energies of gauge theory vacua and it is found that their values are exactly the same as the masses of dual geometries, even though they are in different parameter regimes of 't Hooft coupling. We also consider AdS_5 orbifold. The decay of AdS_5/Z_k is dual to the transition between the dual gauge theory vacua on R_t x S^3/Z_k, parametrized by different holonomies along the orbifolded spatial cycle. We constructed the instanton solutions describing the transitions by making use of instanton solutions on R_t x S^2.

Gunnar Ekelöf’s open-form poem A mölna elegy : problems of genesis, structure and influence
Creators: name: Thygesen, Erik
Publisher: name: University of British Columbia
Year: 2010

description: After being "work in progress" for nearly 23 years, Gunnar Ekelӧf’s long; "Waste Land" poem or quotation-mosaic A Mӧlna Elegy appeared in 1960. For the purposes of this study I have had access to the original manuscripts, notebooks and letters of Gunnar Ekelӧf. Part I As is also the case with T. S. Eliot's: The Waste Land, the critical appraisal of Gunnar Ekelӧf's open-form poem A Mӧlna Elegy has been marked by the dominance of a holistic approach to literature; the work has accordingly been described! either as chaotic and structureless and seen as reflecting Ekelӧf's evolving, contradictory views of art during the long period of genesis or the attempt has been made to reconcile the: chaotic impression which the poem makes with the traditional criterion of "textual, unity" by recourse to: the notion of musical structure or to the idea of the lyrical "I" as focal point and unifying principle. The first part of this: study has been devoted to: an examination of those extrinsic elements in Ekelӧf's world view and aesthetics which motivated his use of the open structure in A Mӧlna. Elegy: his aesthetics of the indistinct and interest in the: active reader role his aesthetics of the incomplete. Works by Egbert Faas, Umberto Eco and Fritjof Capra have provided the conceptual framework for the notion of the open-form, i.e. of Western art forms which make use of trains of thought common to Eastern mysticism and modern physics and to which the traditional notion of "organic unity" is not germane. Part II The second half of this study concerns itself with an exploration of the question of the supposed influence of T. S. Eliot on Gunnar Ekelӧf, the subject of considerable debate among Swedish critics; the centre of interest has been the possible influence of Eliot's Four Quartets on Ekelӧf's collection Ferry Song (1941) and, more importantly, the possible influence of The Waste Land on A Mӧlna Elegy. Several aspects of the Eliot-Ekelӧf interference hypothesis have been examined: the history of Eliot's supposed influence on Ekelӧf in critical circles; Ekelӧf's reception of Eliot-Ekelӧf’s attitude towards the concept of "influence"; his views on the question of his supposed dependency on Eliot; textual similarities in Ekelӧf's work which could conceivably be put forward in support of the Eliot-Ekelӧf influence hypothesis.

description: Context. Nanoflares are small impulsive bursts of energy that blend with and possibly make up much of the solar background emission. Determining their frequency and energy input is central to understanding the heating of the solar corona. One method is to extrapolate the energy frequency distribution of larger individually observed flares to lower energies. Only if the power law exponent is greater than 2, is it considered possible that nanoflares contribute significantly to the energy input. Aims. Time sequences of ultraviolet line radiances observed in the corona of an active region are modelled with the aim of determining the power law exponent of the nanoflare energy distribution. Methods. A simple nanoflare model based on three key parameters (the flare rate, the flare duration time, and the power law exponent of the flare energy frequency distribution) is used to simulate emission line radiances from the ions Fe XIX, Ca XIII, and Si iii, observed by SUMER in the corona of an active region as it rotates around the east limb of the Sun. Light curve pattern recognition by an Artificial Neural Network (ANN) scheme is used to determine the values. Results. The power law exponents, alpha 2.8, 2.8, and 2.6 for Fe XIX, Ca XIII, and Si iii respectively. Conclusions. The light curve simulations imply a power law exponent greater than the critical value of 2 for all ion species. This implies that if the energy of flare-like events is extrapolated to low energies, nanoflares could provide a significant contribution to the heating of active region coronae.

The transparent zooids 15mm tall are densely packed on mangrove roots (Fig. 12 B). The body is colourless except a pale pink tinge of the siphons. Transverse muscles extend over 2/3 of the body wall on each side. They are the only muscles in addition to the siphonal sphincters. The dorsal lamina in a plain membrane carries a languet at its margin at the level of each transverse vessel. Eighteen to twenty longitudinal vessels, almost all entire, lie above 20 rows of stigmata. The stomach has 3 oblique folds. The sperm duct ends in a papilla below the anus at the level of the 6th stigmata row.
 Kott (2003) estimates that E. ndouae is a synonym. This species is smaller, more pigmented, with fewer stigmatal rows but nevertheless mature with incubated larvae. Both species are very similar (Monniot C. 1991). The material is not abundant enough to validate.

Fig. 11; Table 7
Etymology
After the Latin ‘ concinnus ’, meaning ‘harmonic, elegant’ and referring to the ornament.
Type material
Holotype ALGERIA • Gourara, Sebkha de Timimoun 14.5 km west-southwest of Timimoun; “Dalle à Merocanites ” (Tournaisian-Viséan boundary interval); illustrated in Fig. 11; MB.C.30384.
Diagnosis
Species of Vestinautilus with weakly depressed, trapezoidal whorl profile (ww/wh ~ 1.45), venter flattened, ventrolateral shoulder defined by an angular margin produced by a distinct ridge. Another four sharp ridges are located on the outer umbilical wall and two on the outer ventral area. Whorls weakly embracing. Ornament with sharp growth lines on the flank, producing elongate granulation when crossing the spiral ridges; growth lines delicate on the venter forming a deep sinus.
Description
Holotype MB.C.30384 is an incomplete specimen 32 mm in diameter (Fig. 11). It is a thickly discoidal, subevolute conch (ww/dm ~ 0.50; uw/dm ~ 0.45) with a weakly depressed whorl profile (ww/wh ~ 1.45). The whorl profile is subtrapezoidal with a broadly rounded umbilical wall, flattened and weakly converging flanks, a narrowly rounded ventrolateral shoulder and an almost flat venter. The flanks and the marginal part of the venter bear seven ridges. The interspace between the 4 th and the 5 th ridges is deepened to a longitudinal groove. The shell ornament consists of sharp, biconvex growth lines, which are coarsest on the flank; they are even coarser and produce a granulation when crossing the ridges. The suture line is only visible in some parts; broadly rounded ventral and lateral lobes are visible.
Remarks
Vestinautilus concinnus sp. nov. belongs to the species of the genus with a rather slender conch and hence a rather low ratio of whorl width and whorl height; therefore, the new species is easily distinguishable
from most species of the genus including V. padus sp. nov. A fairly similar species is only V. semiglaber, but this species has seven spiral ridges on the flank (V. concinnus sp. nov. has only four) and a weakly concave venter (convex in V. concinnus sp. nov.) (Foord 1900).

description: Der Umgang mit zunehmenden arbeitsbedingten, psychischen Belastungen im Feld der Sozialen Arbeit stellt eine ernstzunehmende Herausforderung für Sozialarbeitende dar, insbesondere in Zeiten des demografischen Wandels und des Fachkräftemangels. Die vorliegende Arbeit geht der Frage nach, welche Strategien Frauenhausmitarbeiterinnen gegen psychische Belastungen am Arbeitsplatz anwenden. Die empirische Untersuchung erfolgte durch neun leitfadengestützte, problemzentrierte Interviews mit insgesamt zehn Frauenhausmitarbeiterinnen aus fünf Bundesländern, welche mithilfe der Grounded Theory-Methodik ausgewertet wurden. Es zeigte sich, dass die Mitarbeiterinnen durch die Zusammenarbeit mit den Klientinnen und die wahrgenommenen Belastungen am Arbeitsplatz wie Arbeitsinhalt, -organisation oder die (eigene) soziale Situation psychische Belastung erleben. Zur Bewältigung dieser Belastung dienen ihnen emotions- und problemorientierte Strategien. Zu den problemorientierten Strategien zählen das Besprechen der Probleme bei Fällen und Erlebtem mit Kolleginnen, Supervisorinnen und innerhalb des beruflichen Netzwerkes, das Setzen von Grenzen, beispielsweise durch eine Auftragsklärung und ein ausgewogenes Nähe-Distanz-Verhältnis sowie die Teilnahme an beruflichen Qualifizierungsmaßnahmen wie Fort- und Weiterbildungen. Auch die Strukturierung/Organisation der Arbeitsaufgaben, der Austausch mit dem Träger und das Besprechen der Problemsituation im Team zählen zu den problemorientierten Lösungsstrategien. Hinsichtlich der emotionsorientierten Bewältigung der psychischen Belastungen wenden die Mitarbeiterinnen Kontrastarbeit an, betreiben eine Uminterpretation der belastenden Situation, nutzen ihren Freizeitausgleich für erbrachte Dienste und besprechen ihre Probleme im privaten Umfeld.

description: We theoretically study the dynamics of typical optomechanical systems, consisting of a passive optical mode and an active mechanical mode, in the $\mathcal{PT}$- and broken-$\mathcal{PT}$-symmetric regimes. By fully analytical treatments for the dynamics of the average displacement and particle numbers, we reveal the phase diagram under different conditions and the various regimes of both $\mathcal{PT}$-symmetry and stability of the system. We find that by appropriately tuning either mechanical gain or optomechanical coupling, both phase transitions of the $\mathcal{PT}$-symmetry and stability of the system can be flexibly controlled. As a result, the dynamical behaviors of the average displacement, photons, and phonons are radically changed in different regimes. Our study shows that $\mathcal{PT}$-symmetric optomechanical devices can serve as a powerful tool for the manipulation of mechanical motion, photons, and phonons.

description: We investigate the influence on the density of states and the density of spin polarization for a two-dimensional hole gas with Rashba spin-orbit coupling under intense terahertz laser fields. Via Floquet theorem, we solve the time-dependent Schrödinger equation and calculate these densities. It is shown that a terahertz magnetic moment can be induced for low hole concentration. Different from the electron case, the induced magnetic moment is quite anisotropic due to the anisotropic spin-orbit coupling. Both the amplitude and the direction of the magnetic moment depend on the direction of the terahertz field. We further point out that for high hole concentration, the magnetic moment becomes very small due to the interference caused by the momentum dependence of the spin-orbit coupling. This effect also appears in two-dimensional electron systems.

description: The transformation of a Laguerre series $f (z) = \sum_{n=0}^{\infty} λ_{n}^{(α)} L_{n}^{(α)} (z)$ to a power series $f (z) = \sum_{n=0}^{\infty} γ_{n} z^{n}$ is discussed. Many nonanalytic functions can be expanded in this way. Thus, success is not guaranteed. Simple sufficient conditions based on the decay rates and sign patters of the $λ_{n}^{(α)}$ as $n \to \infty$ can be formulated which guarantee that $f (z$ is analytic at $z=0$. Meaningful result are obtained if the $λ_{n}^{(α)}$ either decay exponentially or factorially as $n \to \infty$. The situation is much more complicated if the $λ_{n}^{(α)}$ decay algebraically as $n \to \infty$. If the $λ_{n}^{(α)}$ ultimately have the same sign, the series expansions for the power series coefficients diverge, and the corresponding function is not analytic at $z=0. If the $λ_{n}^{(α)}$ ultimately have strictly alternating signs, the series expansions for the power series coefficients are summable and the power series represents an analytic function. In the case of simple $λ_{n}^{(α)}$, the summation of the divergent series for the power series coefficients can often be accomplished with the help of analytic continuation formulas for hypergeometric series, but if the $λ_{n}^{(α)}$ are more complicated, numerical techniques have to be employed. Certain nonlinear sequence transformations -- in particular the so-called delta transformation [E. J. Weniger, Comput. Phys. Rep. \textbf{10}, 189 -- 371 (1989), Eq. (8.4-4)] -- sum the divergent series occurring in this context effectively.

description: We report on experiments that demonstrate dynamical instability in a Bose-Einstein condensate at the band-edge of a one-dimensional optical lattice. The instability manifests as rapid depletion of the condensate and conversion to a thermal cloud. We consider the collisional processes that can occur in such a system, and perform numerical modeling of the experiments using both a mean-field and beyond mean-field approach. We compare our numerical results to the experimental data, and find that the Gross-Pitaevskii equation is not able to describe this experiment. Our beyond mean-field approach, known as the truncated Wigner method, allows us to make quantitative predictions for the processes of parametric growth and thermalization that are observed in the laboratory, and we find good agreement with the experimental results.

 The colonies are attached to the soft coral Carijoa. The yellow translucent zooids are 8mm in length on thin stolons. The siphons are retracted, they have numerous lobes. The atrial aperture is about ¼ the body length behind the oral opening. The musculature consists of transverse fibres in limited areas in the middle of each side, as figured in Monniot C. (1992 fig.2). The branchial sac is thin with 14 stigmata rows. The sperm duct is shorter than the rectum. The testis follicles do not encircle the ovary.
 E. sluiteri is widely distributed in the Indo-Pacific on all types of substrates at shallow depths. It differs from E.diaphanis by the colour, the terminal oral siphon and the lateral cloacal siphon, and a different muscular pattern.

description: Angesichts zunehmender Umweltprobleme und steigender Energiekosten wird die energetische Sanierung des Gebäudebestandes immer wichtiger. Insbesondere bei älteren Gebäuden, die noch nicht den heutigen energetischen Standards entsprechen, besteht ein großes Potenzial zur Reduzierung des Energieverbrauchs. Eine optimierte technische Gebäudeausrüstung (TGA) kann helfen, den Energieverbrauch deutlich zu senken und gleichzeitig den Komfort und die Effizienz des Gebäudebetriebs zu steigern. Die energetische Modernisierung von Gebäuden umfasst verschiedene Maßnahmen zur Verbesserung der Effizienz von Heizung, Lüftung, Kühlung und Beleuchtung. Dies kann durch den Einsatz von Wärmepumpen, die Erneuerung der Dämmung und intelligente Steuerungssysteme erreicht werden. Durch den Austausch veralteter Anlagen und den Einsatz neuer Technologien kann nicht nur der Energieverbrauch gesenkt, sondern auch der CO2-Ausstoß reduziert und damit ein wichtiger Beitrag zum Klimaschutz geleistet werden.

description: We report Hubble Space Telescope imaging obtained 155 days after the 2006 outburst of RS Ophiuchi. We detect extended emission in both [O III] and [Ne V] lines. In both lines, the remnant has a double ring structure. The E-W orientation and total extent of these structures (580+-50 AU at d=1.6kpc) is consistent with that expected due to expansion of emitting regions imaged earlier in the outburst at radio wavelengths. Expansion at high velocity appears to have been roughly constant in the E-W direction (v_{exp} = 3200+-300 km/s in the plane of the sky), with tentative evidence of deceleration N-S. We present a bipolar model of the remnant whose inclination is consistent with that of the central binary. The true expansion velocities of the polar components are then v = 5600+-1100 km/s. We suggest that the bipolar morphology of the remnant results from interaction of the outburst ejecta with a circumstellar medium that is significantly denser in the equatorial regions of the binary than at the poles. This is also consistent with observations of shock evolution in the X-ray and the possible presence of dust in the infrared. Furthermore, it is in line with models of the shaping of planetary nebulae with close binary central systems, and also with recent observations relating to the progenitors of Type Ia supernovae, for which recurrent novae are a proposed candidate. Our observations also reveal more extended structures to the S and E of the remnant whose possible origin is briefly discussed.

description: We present a type theory with some proof-irrelevance built into the conversion rule. We argue that this feature is useful when type theory is used as the logical formalism underlying a theorem prover. We also show a close relation with the subset types of the theory of PVS. We show that in these theories, because of the additional extentionality, the axiom of choice implies the decidability of equality, that is, almost classical logic. Finally we describe a simple set-theoretic semantics.

urn:lsid:zoobank.org:act: 42BD8B9E-A638-4C4F-9472-0B0EE6AB489E
Figs 12–13; Table 8
Diagnosis
Species of Planetoceras with moderately depressed, rounded-pentagonal whorl profile (ww/wh ~ 1.65), venter slightly flattened, ventrolateral shoulder broadly rounded. Umbilical margin subangular to narrowly rounded, umbilical wall steep, flattened. Whorls slightly embracing.
Etymology
After the Latin ‘ destrictum ’, meaning ‘sharp’ and referring to the angular umbilical margin.
Type material
Holotype ALGERIA • Gourara, Sebkha de Timimoun 14.5 km west-southwest of Timimoun; “Dalle à Merocanites ” (Tournaisian-Viséan boundary interval); illustrated in Fig. 12; MB.C.30385.
Description
Specimen MB.C.30385 is a fully chambered specimen with a diameter of 67 mm (Fig. 12). It is a stout, subinvolute conch (ww/dm = 0.76; uw/dm = 0.29) and has a depressed, subtrapezoidal whorl profile with a broadly rounded venter, a rounded ventrolateral shoulder, weakly flattened, slightly converging flanks,
a rounded umbilical margin and a rounded umbilical wall. It has a very high coiling rate (WER = 2.59). The specimen shows a morphological change in the shape of the umbilicus. During the last volution of the phragmocone, the umbilical margin changes from subangular to rounded. At the same time, the umbilical wall changes from flattened to rounded. The suture line extends nearly linearly across the venter and possesses a very shallow lobe on the flank (Fig. 13).
Remarks
Planetoceras destrictum sp. nov. differs from the species described from Belgium, the South Urals and North America in the flattened venter, which is rounded in those species. More similar is P. globatum (Sowerby, 1824), a species with a very similar whorl profile (Histon 1999) but a more slender conch (ww/dm ~ 0.55 at 58 mm dm) than P. destrictum sp. nov. (ww/dm ~ 0.76 at 67 mm dm). Planetoceras transforme sp. nov. (described below) has a much stouter conch (ww/dm ~ 0.85).

Die Auswertung zeigt, dass das verwendete Exoskelett nicht für die dafür vorgesehenen Arbeitsplätze geeignet ist, da es die Mitarbeiter bei ihren Tätigkeiten nur bedingt unterstützt. Ein Exoskelett muss die Nutzer ausreichend unterstützen und darf sie gleichzeitig nicht bei ihrer Arbeit einschränken. Für die erfolgreiche Einführung von Exoskeletten sollte ausreichend Zeit in die Planungsphase und die Auswahl des Produkts investiert werden. Alle beteiligten Personen sollten bereits in dieser Prozessphase eingebunden werden. Darüber hinaus sollte den Mitarbeitenden genügend Zeit gegeben werden, sich an die Arbeit mit Unterstützung durch das Gerät zu gewöhnen.

 Well spaced tiny zooids arise from long thin stolons (Fig. 13). The pale translucent yellow body is no more than 3mm in length. The oral aperture is terminal, the atrial siphon antero-dorsal, both sessile with 8 lobes. An unperforated area lies in front of the 5 stigmatal rows. The stomach is particularly long. This small species is characterised by a single horizontal muscle bundle crossing each side in its middle and dividing into two parts to enclose the atrial siphon (Monniot C. 1997 fig. 2B). This muscular pattern distinguishes P. multiclathrata from P.longigaster Monniot & Monniot, 2008 which has also a long stomach but longitudinal muscles.
 P. multiclathrata is widely distributed in warm shallow waters of all oceans.

description: We study the passage (translocation) of a self-avoiding polymer through a membrane pore in two dimensions. In particular, we numerically measure the probability distribution Q(T) of the translocation time T, and the distribution P(s,t) of the translocation coordinate s at various times t. When scaled with the mean translocation time , Q(T) becomes independent of polymer length, and decays exponentially for large T. The probability P(s,t) is well described by a Gaussian at short times, with a variance that grows sub-diffusively as t^α with α~0.8. For times exceeding , P(s,t) of the polymers that have not yet finished their translocation has a non-trivial stable shape.

description: In the present work we discuss cosmic strings in natural inflation. Our analysis is based entirely on the CMB quadrupole temperature anisotropy and on the existing upper bound on the cosmic string tension. Our results show that the allowed range for both parameters of the inflationary model is very different from the range obtained recently if cosmic strings are formed at the same time with inflation, while if strings are formed after inflation we find that the parameters of the inflationary model are similar to the ones obtained recently.

To be and build the glorious world : the educational thought and practice of Watson Thomson, 1899-1946
Creators: name: Welton, Michael Robert
Publisher: name: University of British Columbia
Year: 2010

description: "To Be and Build the Glorious World" examines the educational thought and practice of Watson Thomson, the most passionate and controversial of the activist educators who worked in Canada from the mid-1930s to the mid-1940s. Using a contextual biographical methodology, the evolution of Thomson's motivational structure and world-view is examined. The opening chapters identify the educative forces that shaped Thomson's transformative-communitarian educational philosophy. Subsequent chapters analyze the interplay of Thomson's transformative- communitarian vision with the Canadian context—Alberta, Manitoba and Saskatchewan. A critical examination of Thomson's educational thought and practice shows that he adopted a consistent modus operandi. For Thomson, study-groups were to be spearheads of social change. Guided by the vision of a new, fully co-operative society, these groups would gradually initiate a social and intellectual revolution. Thomson's spearhead theory, put into practice in many contexts, was most successful in Saskatchewan. There he found support in a left populist culture. Thomson's accomplishments as an adult educator were many. First, he had a significant impact on many individual lives, helping people to see life as an indivisible whole. Second, Thomson participated in, and initiated, a remarkable range of educational ventures, some successful, others not. Thomson's educational thought and practice raises important questions on the relationship between nonformal education, social movements and policy outcomes. Indeed, a close study of Watson Thomson's career reveals the existence of a gentle, but persistent movement towards cultural revitalization in Western Canada in the 1930s and 1940s. Further, it suggests the presence of some unexpected avant-garde themes in the life of the Canadian left. This thesis, then, "explains" Watson Thomson's educational thought and practice contextually. In so doing, it also offers an explanation of the previously undocumented histories of adult education in three prairie provinces.

 The relaxed zooids are erect above a colourless translucent mass (Fig. 14). The muscles have the same pattern as previously described (Monniot & Monniot 1996 figs A,B,C). The fibers issuing from the siphons run vertically, the most ventral of them curve to reach the endostyle, the most dorsal extend onto the abdomen. The thorax has a square shape with numerous stigmatal rows. The stomach is elongated with numerous thin longitudinal folds. The anatomical characters are uniform everywhere. D. angulata was previously found in the Philippines, Malaysia and Indonesia.

description: Patrick (Pat) Wall was a neurophysiologist and true pioneer in the science of pain. He discovered that the sensory information arising from receptors in our body, such as those for touch and heat, could be modified, or ‘gated’, in the spinal cord by other sensory inputs and also by information descending from the brain; this meant, as is now well recognized, that the final sensory experience is not necessarily predictable from the original pain-eliciting sensory input. He used this to explain the poor relationship between injury and pain, and to illustrate the fallacy of judging what someone ‘should’ be feeling from the sensory input alone. In 1969, together with his colleague, Ron Melzack, Pat proposed this ‘gate control theory of pain’ and the circuit diagram that summarized how central spinal cord circuits can modulate sensory inputs. Later on, he began to regret that ‘goddamned diagram’, which had come to dominate his life and work, but, like all great models, it paved the way for the future. Now, over 50 years after it was first published, molecular genetic dissection of dorsal horn neuronal circuitry has indisputably confirmed that sensory inputs are indeed ‘gated’ in the spinal cord dorsal horn. Through a career that started with a medical degree in Oxford, almost 20 years at Yale and MIT in the USA, and continued at UCL in London, Pat Wall was a highly influential, critical, creative and original thinker who revolutionized our understanding of the relationship between injury and pain, and who also became a champion for all who suffered from chronic pain.
