description: Целью исследований была оценка эффективности применения метода электрофореза запасных спирторастворимых белков зерна для первичного семеноводства сортов овса и ячменя селекции Научно-исследовательского института сельского хозяйства Северного Зауралья. Материалом для исследования послужили семьи сортов овса посевного Отрада, Фома и Тоболяк, а также сорта ячменя Абалак. Анализы поводили с 2014 по 2019 года в лаборатории селекции зернофуражных культур НИИСХ Северного Зауралья и лаборатории сортовой идентификации семян ГАУ Северного Зауралья. Установлено, что основу сортов Абалак составляет один биотип с частотой встречаемости 96,58%, генетическая формула гордеина сорта HRD A2 B8 F2. Среди проанализированных семей сорта Тоболяк преобладают (96,45%) семьи с генетической формулой авенина Avn A4 B8 C2, а сорта Фома – семьи с формулой Avn A4 B7 C1. Применение метода электрофореза в первичном семеноводстве сорта Отрада с 2014 по 2018 гг. позволило выявить и удалить из дальнейшего размножения семьи, относящиеся к сортовой примеси – сортовая чистота за годы исследований увеличилась с 75,16 до 95,27%, частота встречаемости гетерозигот снизилась с 15,96 до 4,52%. Общее число выявленных биотипов, отличающихся от основных биотипов сорта, снизилось в 10 раз. Генетическая формула сорта Отрада Avn A10+4 B4 C1. Установлено, что при первом применении метода электрофореза проламинов в системе первичного семеноводства нового сорта необходимо проанализировать не менее 700 семей. Это позволит определить биотипы, составляющие основу сорта, удалить из размножения сортовую примесь и гетерозиготы, а также получить эталонный спектр проламина сорта.

description: Every complex plane curve C determines a subscheme S of the $P^8$ of 3x3 matrices, whose projective normal cone (PNC) captures subtle invariants of C. In "Limits of PGL(3)-translates of plane curves, I" we obtain a set-theoretic description of the PNC and thereby we determine all possible limits of families of plane curves whose general element is isomorphic to C. The main result of this article is the determination of the PNC as a cycle; this is an essential ingredient in our computation in "Linear orbits of arbitrary plane curves" of the degree of the PGL(3)-orbit closure of an arbitrary plane curve, an invariant of natural enumerative significance.

description: One of the main challenges in teaching translation between Spanish and Italian with tourist texts are culture-specific items, both for their referential role – presenting a foreign reality and therefore attractive to the travellers’ eyes– and as functional markers within the communicative context in which they are employed. Although they could be labelled as mere extralinguistic problems since they are related to cultural differences, these culture-specific items might cause other kinds of problems, related to the author’s intention, or depending on the target context and audience of the translated text, i.e. pragmatic problems. So, apart from an exahustive documentation, including out of date bilingual dictionaries –providing, for instance, extended encyclopedic information– and Linguistic Istitutional sites such as Real Academia Española–providing information about neologisms or proper use of anglicisms–, before deciding the right translation strategy for rendering them, we have to take under consideration some other factors, such as the relevance of the culture-specific item and its functions within the specific text employed, as well as the text type and genre, the relationship between the two cultures, etc. In our didactic proposal we present a hybrid text type, the editorial hotel review, written by a travel journalist of El Pais, in which culture-specific words are employed with different purposes and, as a consequence, translation tecniques may vary. Finally, we will underline the relevance of the translator’s "internalised culture" of the language from which he/she translates, as well as his/her intercultural competence who helps to convey the functions of culture-specific items without forgetting the needs of the target audience and always keeping in mind that practical employment of the translated tourist text.

description: Представлены итоги применения инновационных селекционных технологий на основе теории эколого-генетической организации количественных признаков (ТЭГОКП) на основании подбора родительских пар с анализом максимально протяжённых родословных древ сортов – родителей и лим-факторов среды по фазам онтогенеза в зоне выведения каждого родителя. Проведённый фенотайпинг семи генетико-физиологических систем (ГФС), дающим плюсовые и минусовые вклады в урожай: аттракции, микрораспределения, адаптивности, полигенного иммунитета, лимитирующий фактор почвенного питания (N, P, K), толерантности к загущению, вариабельности фаз онтогенеза c лучшим сортом рабочей коллекции. На основании чего подбираются родители с плюсовыми вкладами ГФС в урожай. Проведённой гибридизацией у гибрида совмещаются плюсовые вклады в урожай всех названных ГФС, с последующим насыщением геномом одного из родителей с выраженным ГФС адаптивности. Последующие многолетние стабилизирующие пересевы комбинации устраняют эффекты доминирования, сверхдоминирования и гетерозисного эпистаза. Отбор элитных растений проводится в типичной динамике лим-факторам среды. Применив данную технологию было создано два новых сорта – среднеранняя Гренада – F5 [F1(Казахстанская раннеспелая × Тулунская 12) × Тулунская 12] и среднеспелая -Атланта-2 F9 [F1 (Aisi (оз.) × Латона) × 2 Латона]. Обе комбинации данных сортов имеют хорошо выраженную адаптивность. Цитогенетическая особенность протоплазмы материнских форм обоих сортов обеспечила им выносливость к бурой ржавчине и септориозу, а адаптивный потенциал отцовские сорта хорошо приспрособленные к зоне. Сорт Гренада благодаря хорошо выраженным хозяйственно-ценным признакам и урожайности, зарегистрирован Госкомиссией (2019-2020 гг.) по 9 и 10 регионам РФ. Атланта-2 – передана в Госкомиссию, на испытание с 2021 года.

description: We present magnetic suscceptibility and heat capacity data on a new S=1/2 two-leg spin ladder compound BiCu2PO6. From our susceptibility analysis, we find that the leg coupling J1/k_B is ~ 80 K and the ratio of the rung to leg coupling J2/J1 ~ 0.9. We present the magnetic contribution to the heat capacity of a two-leg ladder. The spin-gap Delta/k_B =3 4 K obtained from the heat capacity agrees very well with that obtained from the magnetic susceptibility. Significant inter-ladder coupling is suggested from the susceptibility analysis. The hopping integrals determined using Nth order muffin tin orbital (NMTO) based downfolding method lead to ratios of various exchange couplings in agreement with our experimental data. Based on our band structure analysis, we find the inter-ladder coupling in the bc-plane J2 to be about 0.75J1 placing the compound presumably close to the quantum critical limit.

description: Derivatives of BODIPY are popular fluorophores due to their synthetic feasibility, structural rigidity, high quantum yield, and tunable spectroscopic properties. While the characteristic absorption maximum of BODIPY is at 2.5 eV, combinations of functional groups and substitution sites can shift the peak position by +/- 1 eV. Time-dependent long-range corrected hybrid density functional methods can model the lowest excitation energies offering a semi-quantitative precision of +/- 0.3 eV. Alas, the chemical space of BODIPYs stemming from combinatorial introduction of -- even a few dozen -- substituents is too large for brute-force high-throughput modeling. To navigate this vast space, we select 77,412 molecules and train a kernel-based quantum machine learning model providing < 2% hold-out error. Further reuse of the results presented here to navigate the entire BODIPY universe comprising over 253 giga (253 x 10^9) molecules is demonstrated by inverse-designing candidates with desired target excitation energies.

description: The relationship between mesonic correlations and quantum condensates in the quark matter phase diagram is explored within a quantum field theoretical approach of the Nambu and Jona-Lasinio (NJL) type. Mean-field values in the scalar meson and diquark channels are order parameters signalling the occurrence of quark condensates, entailing chiral symmetry breaking (chi SB) and color superconductivity (2SC) in quark matter. We investigate the spectral properties of scalar and pseudoscalar meson excitations in the phase diagram in Gaussian approximation and show that outside the chi SB region where the pion is a zero-width bound state, there are two regions where it can be considered as a quasi-bound state with a lifetime exceeding that of a typical heavy-ion collision fireball: (A) the high-temperature chi SB crossover region at low densities and (B) the high-density color superconducting phase at temperatures below 100 MeV.

description: озимые сорта пшеницы выделяются интенсивностью, хорошо развитой вторичной корневой системой, устойчивостью к полеганию, выносливостью к распространённым патогенам и хорошим качеством зерна. В связи с этим, они являются прекрасным исходным материалом для создания интенсивных сортов мягкой яровой пшеницы. При этом важно: если использовать в гибридизации яровизированные озимые сорта, то из-за проявления термофитомутаций у них часто появляются формы с изменённой генетической составляющей, в большинстве своём, экстенсивной направленности. При использовании в гибридизации не яровизированных озимых сортов – при позднем (начало ноября) посеве, одновременно с яровыми формами, которые уходят в зиму в наклюнувшемся состоянии, они практически одновременно выколашиваются, что позволяет проводить гибридизацию неяровизированных озимых и яровых форм. При этом процесс расщепления у гибридов довольно длительный, до F10-F12. В данном случае адаптивные факторы озимых и яровых форм объединяются, что и объясняет выраженную адаптивность, интенсивность и хорошую продуктивность у отобранных из созданных популяций биотипов. Расщепление и формообразовательный процесс у созданных гибридов носит сложный характер. Оценка значимости гибридов проводится в первом – по проявлению гетерозиса и в последующих ранних, расщепляющихся (F2F3) поколениях, по урожаю и его составляющим. Выделено 39 озимых сортов различных агроэкотипов. Выявлена сортообразующая способность ряда из них. Среди изучаемых в селекционном процессе номеров 40% имеют в своём происхождении озимые сорта. Из 56 переданных на Государственное сортоиспытание сортов – 27 (48%) созданы с участием озимых форм. Это говорит о значимости озимых сортов как исходного материала в повышении потенциала мягкой яровой пшеницы.

description: We analyze numerical-relativity (NR) waveforms that cover nine orbits (18 gravitational-wave cycles) before merger of an equal-mass system with low eccentricity, with numerical uncertainties of 0.25 radians in the phase and less than 2% in the amplitude; such accuracy allows a direct comparison with post-Newtonian (PN) waveforms. We focus on one of the PN approximants that has been proposed for use in gravitational-wave data analysis, the restricted 3.5PN ``TaylorT1'' waveforms, and compare these with a section of the numerical waveform from the second to the eighth orbit, which is about one and a half orbits before merger. This corresponds to a gravitational-wave frequency range of $Mω= 0.0455$ to 0.1. Depending on the method of matching PN and NR waveforms, the accumulated phase disagreement over this frequency range can be within numerical uncertainty. Similar results are found in comparisons with an alternative PN approximant, 3PN ``TaylorT3''. The amplitude disagreement, on the other hand, is around 6%, but roughly constant for all 13 cycles that are compared, suggesting that only 4.5 orbits need be simulated to match PN and NR waves with the same accuracy as is possible with nine orbits. If, however, we model the amplitude up to 2.5PN order, the amplitude disagreement is roughly within numerical uncertainty up to about 11 cycles before merger.

description: This deliverable aims to use the relevant oceanographic and ecological data available for the area to test the links among oceanographic processes, explanatory variables, ES, performance indicators and management questions relevant for target species. To protect these sites and the services they provide, these models will be used to understand and predict how the man-induces changes and the resource exploitation could affect the target species at different spatial and temporal scales. The development of case studies on selected Natura 2000 (N2K) sites will also allow testing the usefulness and the relevance of the ecological observing system in the Adriatic Sea (ECOAdS) to support significant management objectives in biodiversity conservation.

“The church was built on a basilica plan.” Translating and mistranslating Italian churches’ panels

Year: 2019
Subjects: translation studies; mistranslation; tourism discourse; corpora

description: Because of its very nature, the tourism experience involves contact with different contexts and cultures, which, once the destination has been reached, may pose cultural and communicative problems because the tourist has to rely on what can be found in situ. In this context, the quantity, and especially the quality, of the information offered can influence the tourist’s enjoyment of the whole experience. This calls for the presence, at an attraction site, of translations of informative texts, whose quality is regarded as an indication of the attention and care taken by the destination for the satisfaction of visitors’ needs. Drawing on relevant scholars (Duran Muñoz; Sumberg; Cappelli “Translation”; Tognini and Manca) working in this context, this paper will investigate how texts provided as panels for visitors have been translated from Italian into English. Attention will be paid to panels found in a few Italian churches (in Milan), since, to the best of our knowledge, little if any research has been done on this topic. The focus of this investigation will be on the main linguistic features characterizing Italian texts and their English translations found on panels, including an analysis of lexical and syntactic elements employed by the authors to express the informative content of texts. Possible mistakes and inaccuracies in the translating process will be presented and explanations will be provided concerning how target language rules and conventions have been violated during the translation process. In addition, a series of possible solutions to improve the quality of this kind of specialized translation will be proposed, in order to suggest best practices.

description: We use double-resonant two-photon laser spectroscopy to measure the dynamic scalar polarizability of the rubidium 5$D_{3/2}$ level, $α^{S}_{5D_{3/2}}$, at a wavelength of $λ=1064$~nm. Since $λ$ is shorter than the photoionization (PI) limit of the Rb 5$D_{3/2}$ level, $α^{S}_{5D_{3/2}}$ depends on both bound-bound and bound-free transition matrix elements. The level also undergoes significant broadening due to PI. The $1064$-nm field is applied in the form of a deep optical lattice ($\sim10^{5}$~photon recoils) generated by an in-vacuum field-enhancement cavity. In our spectroscopic method, we use known dynamic polarizabilities to eliminate the need to measure the light intensity. Our method yields, in atomic units, $α^{S}_{5D_{3/2}}=-524(17)$, in agreement with estimates. Additionally, we extract the $5D_{3/2}$ photoionization cross section $σ$ at $1064$~nm from spectral linewidths; we find $σ=44(1)$~Mb.
The Construction of the Territorial Image in Tourism Websites: The Case of the Veneto Provinces
Creators: name: Cesiri, Daniela
Publisher: name: Altre Modernità

Subjects: language of tourism; computer-mediated communication; corpus linguistics; Veneto tourism promotion

description: Websites are popular platforms for institutional Tourist Boards that want to promote their territories to visitors from all over the world. When tourism promotion is directly conducted by local institutions it entails greater responsibilities for the promoters since they are the real, actual territory introducing itself to prospective tourists. Therefore, the construction of the territorial image is fundamental to convey the aspects that best symbolize the land and that, eventually, will be the reason why tourists will choose to visit the area. This study investigates how local institutions in the Italian region of Veneto promote their districts (a.k.a. ‘provinces’) both in English and in Italian. To do so, the official tourism websites of the seven Veneto provinces are considered. The corpora, composed of texts taken from the websites, are examined quantitatively and qualitatively to identify the most recurrent keywords used in the texts. The aim is to identify the most representative aspects chosen by the seven territories as their symbolic markers, i.e. elements typical of a destination that are selected to provide an iconic, but also stereotypical, image of the local culture they are promoting.

In this paper we give a delay-dependent stability criterion for a wide class of nonlinear stochastic systems including quantum spin systems. We utilize a semi-algebraic problem approach to incorporate the structure of density matrices. To show the effectiveness of the result, we derive a globally stabilizing control law for a quantum spin-1/2 systems in the face of feedback delays.

The proof is based on the theory of Generic Vanishing and higher regularity, and on the Evans-Griffith Syzygy Theorem in commutative algebra. Along the way we give a positive answer, in the setting of Kähler manifolds, to a question of Green-Lazarsfeld on the vanishing of higher direct images of Poincaré bundles. We indicate generalizations to arbitrary Fourier-Mukai transforms.

description: Cortical neurons are subject to sustained and irregular synaptic activity which causes important fluctuations of the membrane potential (Vm). We review here different methods to characterize this activity and its impact on spike generation. The simplified, fluctuating point-conductance model of synaptic activity provides the starting point of a variety of methods for the analysis of intracellular Vm recordings. In this model, the synaptic excitatory and inhibitory conductances are described by Gaussian-distributed stochastic variables, or colored conductance noise. The matching of experimentally recorded Vm distributions to an invertible theoretical expression derived from the model allows the extraction of parameters characterizing the synaptic conductance distributions. This analysis can be complemented by the matching of experimental Vm power spectral densities (PSDs) to a theoretical template, even though the unexpected scaling properties of experimental PSDs limit the precision of this latter approach. Building on this stochastic characterization of synaptic activity, we also propose methods to qualitatively and quantitatively evaluate spike-triggered averages of synaptic time-courses preceding spikes. This analysis points to an essential role for synaptic conductance variance in determining spike times. The presented methods are evaluated using controlled conductance injection in cortical neurons in vitro with the dynamic-clamp technique. We review their applications to the analysis of in vivo intracellular recordings in cat association cortex, which suggest a predominant role for inhibition in determining both sub- and supra-threshold dynamics of cortical neurons embedded in active networks.

description: One of the most significant materials in a solar panel is the glass, which provides transparency, UV protection as well as mechanical and chemical resistance. In this work, we describe the production of prototypes of four solar modules made using borosilicate, zinc-tellurite, Pr$^{3+}$ doped zinc-tellurite, and float glass as cover materials. The performance of these prototypes was evaluated under a solar simulator, and a device was developed to monitor all prototypes under real conditions. A comparison between indoor and outdoor measurements shows that outdoor results are fundamental to evaluate the performance of modified solar modules as the ones considered in this study. In addition, we demonstrate the fundamental role played by the refractive index of cover glasses in the performance of the prototypes, and discuss how this feature could be explored to achieve enhanced devices, as well as other benefits that may arise from this field of research.

description: We present a measurement of the branching fraction $B(D_s^+\toμ^+ν_μ)$ using a 548 fb$^{-1}$ data sample collected by the Belle experiment at the KEKB $e^+e^-$ collider. The $D_s$ momentum is determined by reconstruction of the system recoiling against $DKγX$ in events of the type $e^+e^-\to D_s^\ast DKX, D_s^\ast \to D_sγ$, where $X$ represents additional pions or photons from fragmentation. The full reconstruction method provides high resolution in the neutrino momentum and thus good background separation, equivalent to that reached by experiments at the tau-charm factories. We obtain the branching fraction $B(D_s^+\toμ^+ν_μ) = (6.44 \pm 0.76({\rm stat}) \pm 0.57({\rm syst})) \cdot 10^{-3}$, implying a $D_s$ decay constant of $f_{D_s} = (275 \pm 16({\rm stat}) \pm 12({\rm syst}))$ MeV.

description: We use the three lepton and missing energy "trilepton" signature to search for chargino-neutralino production with 2.0 inverse femtobarns of integrated luminosity collected by the CDF II experiment at the Tevatron ppbar collider. We expect an excess of approximately 11 supersymmetric events for a choice of parameters of the mSUGRA model, but our observation of 7 events is consistent with the standard model expectation of 6.4 events. We constrain the mSUGRA model of supersymmetry and rule out chargino masses up to 145 GeV/c^2 for a specific choice of parameters.

Среди изучаемых вариантов в питомнике конкурсного сортоиспытания в 2015-2020гг. выделен селекционный образец костреца безостого 4-2-20. Проведён сравнительный анализ его продуктивности и показателей качества зелёной массы с сортом-стандартом Лангепас. Образец 4-2-20 среднеспелый, вегетационный период от отрастания до созревания семян 97-114 дней. Урожайность зелёной массы (среднее за 6 лет) составила 23,3т/га, что выше показателя стандарта (21,1т/га) на 2,1т (9,0%). Средний выход сухого вещества составил 8,9 т/га, в благоприятные годы 9-10т/га. Растения в период укоса имели высоту 121 148см, облиственность 37-45%. Содержали 34 42% сухого вещества, 6,2-14% сырого протеина, 29 35% клетчатки. Сбор сырого протеина (среднее за 6 лет) составил 0,88 т/га, у сорта-стандарта – 0,75т/га, превышение на 0,13т/га (17%). Семенная продуктивность образца 4-2-20 за период испытаний была 0,16т/га, у стандарта Лангепас – 0,14т/га, превышение составило 0,02т/га (14%). Образец устойчив к полеганию, технологичен, рекомендуется для сенокосно-пастбищного использования. С возрастом травостой хорошо сохраняет продуктивность, что позволяет использовать его при посеве специальных газонов и в рекультивации нарушенных земель. Селекционный образец костреца безостого 4-2-20 имеет преимущество перед сортом-стандартом Лангепас по основным показателям продуктивности и может быть передан на Государственное сортоиспытание в 2020г. как новый сорт.

description: Graphene is a material of great potential in a broad range of applications, for each of which specific tuning of the materials properties is required. This can be achieved, for example, by covalent functionalization. We have exploited two protocols for surface grafting, either by diazonium salts or by nucleophilic exchange, to perform graphene covalent modification directly on a copper substrate, which is routinely used for the synthesis of the material, and investigated the difference in reactivity compared with other substrates. The successful functionalization was confirmed by Raman and surface-enhanced Raman spectroscopy, mass spectrometry, X-ray photoelectron spectroscopy and scanning electron microscopy with energy-dispersive X-ray spectroscopy. In addition, we have found that the copper substrate can serve as a plasmonic surface enhancing the Raman spectra. Furthermore, the covalent grafting was shown to tolerate the transfer process, thus allowing ex post transfer from copper to other substrates. This protocol avoids wet processing and enables an all-gas-phase transformation of functionalized graphene, which eliminates the main sources of contamination.
Stresses in heavy section electroslag joining
Creators: name: Ivo, Paulo Silveira
Publisher: name: University of British Columbia
Year: 2010

description: A study of the thermal stresses resulting in the Electroslag Joining Process as applied to heavy gauge forgings has been undertaken, since a survey of published reports on the process indicates that although solidification cracking ought to be a problem, apparently it is not routinely observed. Welding conditions which are known to produce solidification cracks in Electroslag Welding with wire electrodes were reported to make crack-free welds using ESJ plate electrodes. This study reports work on the thermal and stress fields developed during ESJ of 150 mm thick A36 steel plates. Conditions predicted by previous workers to form cracks with wire electrodes were established and found not to form cracks with plate electrodes. Measurements of stress and temperature during welding were made and found to agree well with a simple numerical model of the process. It is concluded that the thermal field of ESJ is sufficiently different to ESW that it can relax the stress field developed, even in a fully-constrained joint, to the point at which solidification cracking is no longer observed.
Cercando un yo en fuga: De lejanías de Rosalba Campra

Subjects: identity; autofiction; conversational poetry; intertextuality

description: The search for identity, characteristic of a considerable part of Hispanic American literature, is evident once again, in the poems collected under the title De lejanías by Rosalba Campra in which the author plays with the different formats of the “escrituras del yo” (Different ways to write about myself). However, in spite of this persistent investigation by the author, it is difficult for the reader to grasp her profile because it is continuously escaping, duplicating or it is uncertain or masked. Thus, the text becomes an oxymoron since it reaffirms with persistence an identity through a sentimental or nostalgic confession, but in tracking what is permanent it eludes the same intention of the search.

description: The results of ac and dc magnetic susceptibility isothermal magnetization and heat-capacity measurements as a function of temperature (T) are reported for Sr3NiRhO6 and Sr3NiPtO6 containing magnetic chains arranged in a triangular fashion in the basal plane and crystallizing in K4CdCl6-derived rhombohedral structure. The results establish that both the compounds are magnetically frustrated, however in different ways. In the case of the Rh compound, the susceptibility data reveal that there are two magnetic transitions, one in the range 10 -15 K and the other appearing as a smooth crossover near 45 K, with a large frequency dependence of ac susceptibility in the range 10 to 40 K; in addition, the features in C(T) are smeared out at these temperatures. The magnetic properties are comparable to those of previously known few compounds with partially disordered antiferromagnetic structure. On the other hand, for Sr3NiPtO6, there is no evidence for long-range magnetic ordering down to 1.8 K despite large value of paramagnetic Curie temperature.

description: There is a known tension between cosmological parameter constraints obtained from the primary CMB and those from galaxy cluster samples. One possible explanation could be certain types of groups or clusters of galaxy have been missed in the past. We aim to search for galaxy groups and clusters with particularly extended surface brightness distributions, by creating a new X-ray selected catalog of extended galaxy clusters from the ROSAT All-Sky Survey, using a dedicated algorithm optimized for extended sources. Through extensive simulations, the detection efficiency and sample purity are investigated. Previous cluster catalogs in X-ray and other wave-bands, as well as spectroscopic and photometric redshifts of galaxies are used for the cluster identification. We report a catalog of galaxy clusters at high galactic latitude based on the ROSAT All-sky Survey, named as RXGCC, which includes 944 groups and clusters. Out of it, 641 clusters have been identified through ICM emission previously (Bronze), 154 known optical and infrared clusters are detected as X-ray clusters for the first time (Silver), and 149 identified as clusters for the first time (Gold). Based on 200 simulations, the contamination ratio of the detections which were identified as clusters by ICM emission, and the detections which were identified as optical and infrared clusters in previous work is 0.008 and 0.100, respectively. Compared with Bronze sample, the Gold+Silver sample is less luminous, less massive, and has a flatter surface brightness profile. Specifically, the median flux in [0.1-2.4]keV band for Gold+Silver and Bronze sample is 2.496e-12 erg/s/cm^2 and 4.955e-12 erg/s/cm^2, respectively. The median slope of cluster profile is 0.76 and 0.83 for Gold+Silver and Bronze sample, respectively.

description: The coincidence site lattices of the root lattice $A_4$ are considered, and the statistics of the corresponding coincidence rotations according to their indices is expressed in terms of a Dirichlet series generating function. This is possible via an embedding of $A_4$ into the icosian ring with its rich arithmetic structure, which recently (arXiv:math.MG/0702448) led to the classification of the similar sublattices of $A_4$.

description: In previous work, the Hamilton-Jacobi equation has been associated with the metrics of general relativity and shown to be a generalized Dirac equation for quantum mechanics. This lends itself to a natural definition of wave-particle duality. This theory is now further developed to show that a free spinless quantum particle moving with velocity v obeys the standard wave equation of electro-magnetism. We also discuss the implications for the zitterbewegung problem and its relationship to isotropy. Moreover, it is shown that for the theory to be consistent, the momentum defined by the Hamilton-Jacobi function presupposes the existence of a universal parameter internal to the system defined by dt/m(t) for particles with mass, where t has the units of time and m = m(t) has the units of mass.

description: The compound Y2PdGe3 was earlier reported by us to be one of the very few ternary superconducting compounds (T_c= 3 K) belonging to the same structure as that of MgB2. Here we report the results of electrical resistivity, magnetization and heat capacity measurements at low temperatures on the solid solution with a nominal starting composition, Y2Pd(1-x)Pt(x)Ge3, to understand the influence of gradual replacement of Pd by Pt on T_c. The superconducting properties of this solution is distinctly interesting in the sense that the Tc varies monotonically with increasing x in sharp contrast to the non-monotonic variation for other isostructural solid solutions reported recently.
