description: We investigate the effect of the dipole-dipole interaction on the quantum jump statistics of three atoms. This is done for three-level systems in a V configuration and in what may be called a D configuration. The transition rates between the four different intensity periods are calculated in closed form. Cooperative effects are shown to increase by a factor of 2 compared to two of either three-level systems. This results in transition rates that are, for distances of about one wavelength of the strong transition, up to 100% higher than for independent systems. In addition the double and triple jump rates are calculated from the transition rates. In this case cooperative effects of up to 170% for distances of about one wavelength and still up to 15% around 10 wavelengths are found. Nevertheless, for the parameters of an experiment with Hg+ ions the effects are negligible, in agreement with the experimental data. For three Ba+ ions this seems to indicate that the large cooperative effects observed experimentally cannot be explained by the dipole-dipole interaction.

description: The Tamtsag Basin in NE Mongolia is part of a widespread basin system which formed during Late Jurassic and Cretaceous times (Graham et al. 2001, Qing-Ren et al. 2003). It is filled with continental sediments and volcanics which can reach up to 4 km in thickness. Rifting and subsequent basin inversion led to a complex basin geometry characterized by several horst and graben structures. The geodynamic causes for regional basin formation are discussed controversially and several hypothesis ranging from orogenic collaps via subduction rollback to collision-induced rifting have been put forward. Scientific research on the Mesozoic basins in Mongolia has so far concentrated on the East Gobi Basin to the south (Graham et al 2001, Prost 2004, Johnson 2004) and some work has also been published on the Hailar Basin (Qing-Ren et al. 2003), the northeastward continuation of the Tamtsag Basin into China. Fundamental data on the fill and tectonics of the Tamtsag Basin in between is still missing. This is partly due to poor exposure as most of the basin fill is covered by Cenozoic sediments and only locally, near the bordering faults, rocks are accessible for surface investigations. However, recent discoveries of oil in the Tamtsag and Hailar Basins have resulted in intense exploration activity and a strong interest in the area. This contribution describes the results of a field campaign in fall 2005 focusing on the basin fill while a companion paper (Davaa et al. this volume) deals with the basin structure and hydrocarbon potential of the Tamtsag Basin.

description: In order to determine the relationship between the faint X-ray and faint radio source populations, and hence to help understand the X-ray and radio emission mechanisms in those faint source populations, we have made a deep 1.4GHz Very Large Array radio survey of the 13h +38deg XMM/ROSAT X-ray Survey Area. From a combined data set of 10hours B configuration data and 14hours A configuration data, maps with 3.35'' resolution and a noise limit of 7.5uJy were constructed. A complete sample of 449 sources was detected within a 30' diameter region above a 4sigma detection limit of 30uJy, at the map centre, making this one of the deepest radio surveys at this frequency. The differential source count shows a significant upturn at sub-milliJansky flux densities, similar to that seen in other deep surveys at 1.4GHz (eg the Phoenix survey), but larger than that seen in the HDF which may have been selected to be under-dense. This upturn is well modelled by the emergence of a population of medium redshift starforming galaxies which dominate at faint flux densities. The brighter source counts are well modelled by AGNs.

title: The involvement of the Church of Pakistan in development
Creators: name: Sultan, Pervaiz
Publisher: name: The Open University
Year: 1997

description: This research critically examines the involvement of the Church of Pakistan in development of the poor people by way of a comparative case-study of two key dioceses, Multan and Hyderabad. The development priorities in the Dioceses studied have been defined and adopted mainly by the Diocesan Bishops of Multan and Hyderabad, J. V. Samuel and Bashir Jiwan who both by interaction with the local context as well as by exposure to externally produced theological discourses i. e. ecumenical and evangelical respectively, developed distinct approaches to mission and development in their dioceses, thus having `conscientization' and `evangelization' as specific aims of development respectively. Therefore, conscientization and evangelization as overruling diocesan motivating philosophies along with sample development projects have been analyzed. The diocesan aims of conscientization and evangelization were examined in the light of the `wholism' projected by the Biblical materials. The involvement of the Church of Pakistan in development has been highlighted in the contexts of a feudal and religiously biased national and the international secular development debate. With the objective of discussing the applicability of the two respective theologies for strengthening the mission understanding within the Church of Pakistan and the Church worldwide, the findings of this research have provided a base for the proposition of more realistic components of a theology of development for Pakistan.
Eiszerfallsformen, Esker sowie subglaziale und subaerische Talbildungen am Lütjensee / Forst Seebergen (Stormarn, Schleswig-Holstein)
Creators: name: Grube, Alf
Publisher: name: Geozon Science Media
Year: 2016

description: This article presents investigations of a diverse landscape in the young moraine area of southeastern Schleswig-Holstein (Stormarn county). The northern part of the study area represents a large basin, possibly a glacier basin influenced by glaciofluvial meltwaters or by dead ice. Organic sedimentation occurred in this basin from the Late-glacial (Bölling/Alleröd interstadial complex), followed by a longer lake phase and the growth of a fen after c. 5.000 14C a B.P. The central area of the basin was formed as ice-disintegration landscape – including kames, eskers and esker-like features. Ring-like glaciofluvial landform structures are interpreted as subcircular eskers. Kettle bogs developed in the centres of these landforms from c. 5.000 14C a BP (Atlantic/Subboreal) onwards. The southern and south-eastern part of the study area represents a smoothed moraine zone, that includes a glaciotectonically influenced Saalian core of till, sand and glacilacustrine sediment. Parallel aligned gullies were predominantly formed as tunnel valleys. Some parts of the channels are infilled with glaciolacustrine clays. Several channels, asymmetric in cross-profile, were shaped by periglacial slope denudation.

description: A birth-death lattice gas model about the influence of an environment on the fitness and concentration evolution of economic entities is analytically examined. The model can be mapped onto a high order logistic map. The control parameter is a (scalar) "business plan". Conditions are searched for growth and decay processes, stable states, upper and lower bounds, bifurcations, periodic and chaotic solutions. The evolution equation of the economic population for the best fitted companies indicates "microscopic conditions" for cycling. The evolution of a dynamic exponent is shown as a function of the business plan parameters.

description: Neural architecture search (NAS) has emerged as a promising avenue for automatically designing task-specific neural networks. Existing NAS approaches require one complete search for each deployment specification of hardware or objective. This is a computationally impractical endeavor given the potentially large number of application scenarios. In this paper, we propose Neural Architecture Transfer (NAT) to overcome this limitation. NAT is designed to efficiently generate task-specific custom models that are competitive under multiple conflicting objectives. To realize this goal we learn task-specific supernets from which specialized subnets can be sampled without any additional training. The key to our approach is an integrated online transfer learning and many-objective evolutionary search procedure. A pre-trained supernet is iteratively adapted while simultaneously searching for task-specific subnets. We demonstrate the efficacy of NAT on 11 benchmark image classification tasks ranging from large-scale multi-class to small-scale fine-grained datasets. In all cases, including ImageNet, NATNets improve upon the state-of-the-art under mobile settings ($\leq$ 600M Multiply-Adds). Surprisingly, small-scale fine-grained datasets benefit the most from NAT. At the same time, the architecture search and transfer is orders of magnitude more efficient than existing NAS methods. Overall, the experimental evaluation indicates that, across diverse image classification tasks and computational objectives, NAT is an appreciably more effective alternative to conventional transfer learning of fine-tuning weights of an existing network architecture learned on standard datasets.

description: The DAMA collaboration reported an annually modulated rate with a phase compatible with a Dark Matter induced signal. We point out that a slowly varying rate can bias or even simulate an annual modulation if data are analyzed in terms of residuals computed by subtracting approximately yearly averages starting from a fixed date, rather than a background continuous in time. In the most extreme case, the amplitude and phase of the annual modulation reported by DAMA could be alternatively interpreted as a decennial growth of the rate. This possibility appears mildly disfavoured by a detailed study of the available data, but cannot be safely excluded. In general, a decreasing or increasing rate could partially reduce or enhance a true annual modulation, respectively. The issue could be clarified by looking at the full time-dependence of the DAMA total rate, not explicitly published so far.

description: We show that thermodynamics is insufficient to probe the nature of the low energy dynamics of quantum impurity models and a more subtle analysis based on scattering theory is required. Traditionally, quantum impurity models are classified into one of two categories: Fermi liquids and non-Fermi liquids, depending on the analytic properties of the various thermodynamic quntities. We show, however, that even when a quantum impurity model is a Fermi liquid (an incoming electron at the Fermi level scatters elastically off the impurity), one may find singular thermodynamic behavior if characteristics of quasiparticles are not analytic near the Fermi surface. Prompted by this observation, we divide Fermi liquids into two categories: regular Fermi liquids and singular Fermi Liquids. The difference between regular Fermi liquids, singular Fermi liquids, and non-Fermi liquids fixed points is explained using properties of the many-body S-matrix for impurity quasiparticle scattering. Using the Bethe-Ansatz and numerical RG, we show that whereas the ordinary Kondo Model is a regular Fermi liquid the underscreened Kondo model is a a singular Fermi liquid. This results in a breakdown of Nozieres' Fermi liquid picture for the underscreened and explains the singular thermodynamic behavior noticed in Bethe Ansatz and large-N calculations. Furthermore, we show that conventional regular Fermi liquid behavior is re-established in an external magnetic field H, but with a density of states which diverges as 1/H. Possible connections with the field-tuned quantum criticality recently observed in heavy electron materials are also discussed.

The Appropriateness of Specific Package of Technological Practices for Weed Control in Peanut Cultivation in Jamaica

description: In Jamaica, scarce foreign exchange makes it very important to examine carefully every aspect of technology employed in agricultural production to ascertain its appropriateness to local conditions and particularly its labour employment opportunity. On small farms where a fraction of an acre is involved in peanut production it is most advantageous for optimum utilization of family labour to employ manual methods of weed control. In this way family income is optimized. Improved cultural practices and management involving maximization of land use would increase the efficiency and effectiveness of manual methods of weed control on small farms which collectively could supply Jamaica's needs for "ball park" peanuts. Peanut industrial development in Jamaica however depends on expansion of the size of individual areas devoted to this crop. With increased size of areas, manual methods of weed control become less desirable. It would be disastrous, as far as efficiency is concerned, to depend on a large number of hired workers employing manual methods of hired workers employing manual methods of weed control only on individually large areas of peanut production. Economy and competitiveness of the final product will dictate a shift to a higher level of technology and capitalization involving the use of chemicals and fuel powered cultivators. Although an integrated system involving all methods of weed control is essential for successful peanut production it would be unwise to specify any particular package of technological practices for weed control as the desirability of any practice or group of practices varies widely with circumstances and is determined by optimization of income, factor utilization and the satisfaction of well-being.

description: The interaction between the intersecting noncommutative D-branes (or membranes) is investigated within the M(atrix) theory. We first evaluate the spectrum of the off-diagonal fluctuation and see that there is a tachyon mode, which signals the instability of the intersecting branes. We next explain in detail how the tachyon modes (which are the off-diagonal fluctuations) can be combined with the original branes (which are the diagonal elements) to become a new diagonal matrix, which then represents the new recombined configurations after the tachyon condensation. The tachyon condensation configurations of the noncommutative branes we find are different from those of the commutative cases studied in the previous literatures.

description: Crop information relevant to weed control and weeds prevalent in peanut plantings are mentioned. Pre-planting and post-planting weed control treatments are discussed. Prior to planting attention should be focussed on effective control of perennial weeds and proper soil cultivation in order to reduce potential weed regeneration. Subsequently an adequate preemergence herbicide treatment should be practiced in preference to mechanical control to combat weeds in the crop. However, no herbicide treatment has been found for season-long control under the prevailing weather conditions in Suriname. Of the herbicides tested alachlor (1.70 — 2.60 has proven to be most appropriate. Very clean fields at harvest are obtained if hilling is practiced at about 4 weeks after sowing in addition to pre-emergence herbicide use. In general no adverse effects on the crop have been recorded, neither quantitatively nor qualitatively, following proper pre-emergence herbicide use. Compared with mechanical weeding, either by hand-hoe or machine equal or better yields have been obtained, the effect of hilling being slightly beneficial at best. Time recordings have shown that the total labour requirement for the traditional method of land preparation, weeding and hilling can be reduced from about 700 man hours/ha to 80-100 man hours/ha if small machines and herbicides are used. x=?t : kg active ingredient per ha

description: Awareness and adoption of chemical weed control in peanut farming and the use of communication channels among peanut cultivating farmers was studied. One and a half years after its introduction 17% of the farmers had adapted this innovation. A large group was still not aware of the innovation. Lack of knowledge was the major constraint to its adoption. Adescription is given of the process by which information on improved farm practices goes from the source, in this case the Agricultural Experiment Station, to the farmers. Constraints which may have hindered a more effective flow of information to the farmer are discussed.

description: COSINE-100 is a dark matter detection experiment that uses NaI(Tl) crystal detectors operating at the Yangyang underground laboratory in Korea since September 2016. Its main goal is to test the annual modulation observed by the DAMA/LIBRA experiment with the same target medium. Recently DAMA/LIBRA has released data with an energy threshold lowered to 1 keV, and the persistent annual modulation behavior is still observed at 9.5$σ$. By lowering the energy threshold for electron recoils to 1 keV, COSINE-100 annual modulation results can be compared to those of DAMA/LIBRA in a model-independent way. Additionally, the event selection methods provide an access to a few to sub-GeV dark matter particles using constant rate studies. In this article, we discuss the COSINE-100 event selection algorithm, its validation, and efficiencies near the threshold.

description: Die Yarimburgaz-Höhle am Bosporus ist die wichtigste Fundstelle für die mittelpleistozäne Archäologie und Paläontologie im nordöstlichen Mittelmeerraum und beinhaltet in diesem Zeitraum die reichste Fledermausfauna der Region. Aus der Lokalität werden hier die Chiropteren anhand von Crania, Mandibulae und Humeri untersucht. Es sind mindestens 14, eventuell bis zu 16 Arten aus den Gattungen Rhinolophus, Myotis, Miniopterus und Plecotus vorhanden, wodurch die bisherige Fossilfauna um weitere neun bis elf Arten ergänzt wird. Von den drei Sedimentationszyklen enthält der älteste, Zyklus I, die meisten Fledermausfunde. Unter den acht verschiedenen Arten sind Rhinolophus mehelyi und Myotis blythii am häufigsten vertreten und weisen auf mediterranes Klima mit kühlen, regnerischen Wintern und heißen, trockenen Sommern hin (Krystufek & Vohralik 2001). Aus Sedimentationszyklus II sind außer einer Mandibel von R. mehelyi keine weiteren Funde überliefert. Zyklus III beinhaltet mit insgesamt sechs Taxa wesentlich weniger Funde als Zyklus I. Darunter sind Myotis blythii und Miniopterus schreibersi die dominierenden Arten. Verglichen mit den Rodentia und Lagomorpha aus der Yarimburgaz-Höhle, die als Einwanderer des südrussischen Steppengürtels mehrere kälteangepaßte Arten umfassen und rezent nicht mehr in Thrazien vorkommen, kann ein inhomogenes Klima angenommen werden, mit wechselweise kühleren, trockeneren, aber auch wärmeren Phasen, welche durch die Fledermäuse angedeutet werden.

description: We report the results of an experimental investigation into the decay of turbulence in plane Couette-Poiseuille flow using 'quench' experiments where the flow laminarises after a sudden reduction in Reynolds number $Re$. Specifically, we study the velocity field in the streamwise-spanwise plane. We show that the spanwise velocity containing rolls, decays faster than the streamwise velocity, which displays elongated regions of higher or lower velocity called streaks. At final Reynolds numbers above 425, the decay of streaks displays two stages: first a slow decay when rolls are present and secondly a more rapid decay of streaks alone. The difference in behaviour results from the regeneration of streaks by rolls, called the lift-up effect. We define the turbulent fraction as the portion of the flow containing turbulence and this is estimated by thresholding the spanwise velocity component. It decreases linearly with time in the whole range of final $Re$. The corresponding decay slope increases linearly with final $Re$. The extrapolated value at which this decay slope vanishes is $Re_{a_z}\approx 656\pm10$, close to $Re_g\approx 670$ at which turbulence is self-sustained. The decay of the energy computed from the spanwise velocity component is found to be exponential. The corresponding decay rate increases linearly with $Re$, with an extrapolated vanishing value at $Re_{A_z}\approx 688\pm10$. This value is also close to the value at which the turbulence is self-sustained, showing that valuable information on the transition can be obtained over a wide range of $Re$.

Year: 1993

description: Verschieden alte, datierte Böden auf den Niederterrassen des Rheins werden mikromorphologisch charakterisiert und ausgewählte Merkmale dem Bodenalter gegenübergestellt. Klare Beziehungen zum Alter zeigen. Entkalkung und Tonwanderung. Bereits in der Gruppe der 1800jährigen Böden wird eine Entwicklung sichtbar. Ab 6000 Jahren kommen Parabraunerden vor. Stark entwickelt sind die Böden auf präholozänen Sedimenten. Die Bodenbildung in situ wird vom Wechselspiel aus Bodenentwicklung und -abtrag im Liefergebiet der Sedimente mitbestimmt. Die im Liefergebiet begonnene Silicatverwitterung läuft in der Aue weiter, während die Horizontdifferenzierung durch Tonverlagerung nach dem Transport in der Aue neu beginnt. Die Böden aus präholozänen Sedimenten können kurzstreckig verlagertes Material von Bt-Horizonten eemzeitlicher Böden enthalten. Die systematische Stellung der Böden wird diskutiert. Die Bedeutung der Tonwanderung zwischen Sandkörnern wird anhand verdichteter Böden des Versuchsgutes Wahn dargestellt.

description: We are concerned with sequences of graphs having a grid geometry, with a uniform local structure in a bounded domain $Ω\subset {\mathbb R}^d$, $d\ge 1$. We assume $Ω$ to be Lebesgue measurable with regular boundary and contained, for convenience, in the cube $[0,1]^d$. When $Ω=[0,1]$, such graphs include the standard Toeplitz graphs and, for $Ω=[0,1]^d$, the considered class includes $d$-level Toeplitz graphs. In the general case, the underlying sequence of adjacency matrices has a canonical eigenvalue distribution, in the Weyl sense, and we show that we can associate to it a symbol $f$. The knowledge of the symbol and of its basic analytical features provide many informations on the eigenvalue structure, of localization, spectral gap, clustering, and distribution type. Few generalizations are also considered in connection with the notion of generalized locally Toeplitz sequences and applications are discussed, stemming e.g. from the approximation of differential operators via numerical schemes.

description: In three field experiments conducted at the experimental farm of Coebiti the effects of nitrogen, phosphorus, potassium and lime on the growth and quality of sugar cane were studied for the past two years. Phosphate and potassium had significant positive effects on the leaf content, but not on the yield. Nitrogen did not influence both the leaf content and the yield. Liming raised the leaf content and the yield significantly, but reduced the sugar content, on the other hand. The effects of rock phosphate from Curasao, which raised the soil pH, were similar to those of liming. From the results of the first two years it was decided to lower the levels of the nitrogen, phosphorus and potassium dressings.

description: In spite of the part played by the Yam tuber in the clone perennity and economical value, its anatomy remains insufficiently studied. A simple study of D, alata, D. trifida, D. cayenensis, D. escu/enta and D. transversa sets up characters which enlighten tue species biology. In D. alata a very specific sclerenchymatous zone is interpreted as transfusion tissue. In all the species, cellular blocks, within the inner cortical parenchyma, make up the organizing poles of the tuber part set germination.
Mass-loss rates for hot luminous stars: the influence of line branching

Subjects: subject: Astrophysics (astro-ph)

description: The effect of photon frequency redistribution by line branching on mass-loss rates for hot luminous stars is investigated. Monte Carlo simulations are carried out for a range of OB-star models which show that previous mass-loss calculations which neglect non-resonance line scattering overestimate mass-loss rates for luminous O stars by ~20 per cent. For luminous B stars the effect is somewhat larger, typically ~50 per cent. A Wolf-Rayet star model is used to investigate line branching in the strong wind limit. In this case the effect of line branching is much greater, giving mass-loss rates that are smaller by a factor ~3 from computations which neglect branching.

description: If NISQ-era quantum computers are to perform useful tasks, they will need to employ powerful error mitigation techniques. Quasi-probability methods can permit perfect error compensation at the cost of additional circuit executions, provided that the nature of the error model is fully understood and sufficiently local both spatially and temporally. Unfortunately these conditions are challenging to satisfy. Here we present a method by which the proper compensation strategy can instead be learned ab initio. Our training process uses multiple variants of the primary circuit where all non-Clifford gates are substituted with gates that are efficient to simulate classically. The process yields a configuration that is near-optimal versus noise in the real system with its non-Clifford gate set. Having presented a range of learning strategies, we demonstrate the power of the technique both with real quantum hardware (IBM devices) and exactly-emulated imperfect quantum computers. The systems suffer a range of noise severities and types, including spatially and temporally correlated variants. In all cases the protocol successfully adapts to the noise and mitigates it to a high degree.

The effects of flossing with a chlorhexidine solution on interproximal gingivitis : a randomized controlled trial
Creators: name: Imai, Pauline H.
Publisher: name: University of British Columbia
Year: 2011

description: Background: Gingivitis, which is an inflammatory response of the gingival tissues to bacterial plaque, can be treated by brushing and flossing or using chlorhexidine (CHX). Objective: To determine whether floss presoaked in CHX would improve oral health relative to floss presoaked in placebo solution. Materials and methods: A 3 month, double-blinded, parallel, randomized control trial was conducted on 27 adults with a minimum of 10 bleeding sites, who were randomly assigned to dental floss with 0.12% CHX or a placebo solution (QS). Scaling, rubber cup prophylaxis, and flossing instructions were performed at Week -1. Subjects were assessed for probing depth (PD) with bleeding on probing (BOP), gingival index (GI), plaque index (PI), and stain index (SI) at Weeks 0, 6, and 12. Flossing compliance was monitored by self-reports and yards of dental floss used. Student t-tests, ANCOVA and Wilcoxon Signed-Rank were conducted. Results: Self-reported median flossing compliance was 100% for CHX and 93% for QS. A statistically significant reduction for PD in the CHX group at Week 6 (p = 0.029) and specifically, for the gingivitis sites at Week 6 (p = 0.006) and Week 12 (p = 0.005). Reductions in BOP were statistically significant for CHX group with moderate gingivitis (p = 0.0078). The CHX group had a statistically significant reduction in BOP in all areas of the oral cavity with the largest reductions occurring in the anterior areas (p = 0.011). All GI scores were statistically significant from Weeks 0 to 12 (p < 0.0001). Although not statistically significant, PI appeared to be constant for CHX group and increasing for QS group. The two groups did not differ significantly for SI. Conclusion: CHX applied via dental floss significantly reduced probing depths in shallow sulci and bleeding in subjects with moderate gingivitis. Further studies are suggested to determine the effects of CHX with different interdental aids, higher concentrations of CHX, and subjects with moderate to severe gingivitis.

description: Generation of extreme bright coherent synchrotron radiation in a short wavelength range is of remarkable interest in the synchrotron light source community. In this paper, a novel technique is adopted to produce the coherent radiation which uses an angular dispersion to enhance the micro-bunch by a tiny amplitude of energy modulation. This scheme can be inserted in a long straight section of a storage ring. A lattice design of an extreme-low emittance storage ring with 3.5 GeV energy is presented in this paper, which employs a higher order achromat (HOA) concept. We show the design results for the multi-bend achromat (MBA) lattice with an emittance of 20 pm-rad in about 900-meter circumference. Numerical simulations demonstrated that this angular dispersion induced micro-bunch scheme can be used to generate coherent radiation near soft x-ray region, the repetition rate can reach 10 kHz and the spectral brightness can reach 3*10^24phs/s/mm^2/mrad^2/0.1%BW.
X-ray Temperatures for the EMSS High Redshift Cluster Sample: Constraints on Cosmology and the Dark Energy Equation of State

description: We measure the X-ray temperature (and luminosity) with ASCA of all but one cluster in the Einstein Extended Medium Sensitivity Survey (EMSS) high redshift (z > 0.3) sample. We compare these data to a complete sample of low redshift clusters that also has temperature measurements, thereby providing cosmological constraints. We incorporate many improvements over our previous work. We find an allowed band in the Omega_{m0} - Omega_{Lambda0} plane of different orientation to the band of constraints provided by the supernovae Ia Hubble diagram and the cosmic microwave background fluctuations. All three bands intersect at the same place: Omega_{m0} ~ 0.3, Omega_{Lambda0} ~ 0.7. We measure the quintessence equation of state parameter to be w = -(0.42 pm 0.21) (68% confidence for 1 interesting parameter), consistent with previously determined upper limits. We measure the normalization of the mass fluctuation power spectrum to be sigms_8 = 0.66 pm 0.16 (68% confidence for 3 interesting parameters). Systematic errors are larger than the statistical errors only for sigma_8 with our sample, thus the errors for it depends on the details of the marginalization over the temperature - mass normalization.

description: Let $H$ be a non-semisimple Hopf algebra with antipode $S$ of dimension $pq$ over an algebraically closed field of characteristic 0 where $p \le q$ are odd primes. We prove that $\Tr(S^{2p})=p^2d$ where $d \equiv pq \pmod{4}$. As a consequence, if $p,q$ are twin primes, then any Hopf algebra of dimension $pq$ is semisimple.

description: We consider the trapping reaction A + B -> B in space dimension d=1, where the A and B particles have diffusion constants D_A, D_B respectively. We calculate the probability, Q(t), that a given A particle has not yet reacted at time t. Exploiting a recent formulation in which the B particles are eliminated from the problem we find, for t -> \infty, $Q(t) \sim \exp[-(4/\sqrtπ)(ρ^2 D_Bt)^{1/2} - (C ρ^2 D_A t)^{1/3} + ...]$, where $ρ$ is the density of B particles and $C \propto D_A/D_B$ for $D_A/D_B << 1$.
