description: Fractional calculus, in allowing integrals and derivatives of any positive order (the term "fractional" kept only for historical reasons), can be considered a branch of mathematical physics which mainly deals with integro-differential equations, where integrals are of convolution form with weakly singular kernels of power law type. In recent decades fractional calculus has won more and more interest in applications in several fields of applied sciences. In this lecture we devote our attention to wave propagation problems in linear viscoelastic media. Our purpose is to outline the role of fractional calculus in providing simplest evolution processes which are intermediate between diffusion and wave propagation. The present treatment mainly reflects the research activity and style of the author in the related scientific areas during the last decades.

description: Blazars constitute the most interesting and enigmatic class of extragalactic gamma-ray sources dominated by non-thermal emission. In this Letter, we show how the WISE infrared data make possible to identify a distinct region of the [3.4]-[4.6]-[12] micron color-color diagram where the sources dominated by the the thermal radiation are separated from those dominated by non-thermal emission, in particular the blazar population. This infrared non-thermal region delineated as the WISE Blazar Strip (WBS), it is a powerful new diagnostic tool when the full WISE survey data is released. The WBS can be used to extract new blazar candidates, to identify those of uncertain type and also to search for the counterparts of unidentified gamma-ray sources. We show one example of the value of the use of the WBS identifying the TeV source VER J 0648+152, recently discovered by VERITAS.

description: We study a variant of the ferromagnetic Potts model, recently introduced by Tamura, Tanaka and Kawashima, consisting of a ferromagnetic interaction among $q$ "visible" colours along with the presence of $r$ non-interacting "invisible" colours. We introduce a random-cluster representation for the model, for which we prove the existence of a first-order transition for any $q>0$, as long as $r$ is large enough. When $q>1$, the low-temperature regime displays a $q$-fold symmetry breaking. The proof involves a Pirogov-Sinai analysis applied to this random-cluster representation of the model.

description: Recent polarimetric surveys of extragalactic radio sources (ERS) at frequencies ν>1GHz are reviewed. By exploiting all the most relevant data on the polarized emission of ERS we study the frequency dependence of polarization properties of ERS between 1.4 and 86GHz. For flat-spectrum sources the median (mean) fractional polarization increases from 1.5% (2-2.5%) at 1.4GHz to 2.5-3% (3-3.5%) at ν>10GHz. Steep-spectrum sources are typically more polarized, especially at high frequencies where Faraday depolarization is less relevant. As a general result, we do not find that the fractional polarization of ERS depends on the total flux density at high radio frequencies, i.e >20GHz. Moreover, in this frequency range, current data suggest a moderate increase of the fractional polarization of ERS with frequency. A formalism to estimate ERS number counts in polarization and the contribution of unresolved polarized ERS to angular power spectra at Cosmic Microwave Background (CMB) frequencies is also developed and discussed. As a first application, we present original predictions for the Planck satellite mission. Our current results show that only a dozen polarized ERS will be detected by the Planck Low Frequency Instrument (LFI), and a few tens by the High Frequency Instrument (HFI). As for CMB power spectra, ERS should not be a strong contaminant to the CMB E-mode polarization at frequencies ν>70GHz. On the contrary, they can become a relevant constraint for the detection of the cosmological B--mode polarization if the tensor-to-scalar ratio is <0.01.

description: The above article deals with Friedrich Gilbert´s didactical writings on how to learn the Chinese script with the help of a method based on mnemonic principles. The underlying idea of this method (Gilbert calls it the “Mebiwegal Method”) is, that Chinese characters are easy to learn if you tag them with mnemonic labels and form verbal picture systems (“Bildsysteme”) for their graphemic components. Based on his method Gilbert published a Chinese Learners Dictionary which is in turn described and analysed. Finally the advantages and disadvantages of Gilberts method are discussed.

In my opinion, anyone now wishing to become an interpreter for Chinese, must as well as being informed on Chinese affairs, also acquire a specialist knowledge of the Federal Republic of Germany.

description: The report begins by providing an overview of the European landscape (See top half of Figure 1) that supports the CPS domain, covering a range of EU programmes, Industrial Associations, PPPs and supporting technology hubs. A survey of European technology providers has been performed (with a focus on Large Industry and SMEs) to identify stakeholders in the CPS ecosystem. This has identified the technologies being provided or currently under development, the targeted application domains, existing industrial alliances, and standards being supported or developed. This was done by surveying existing lists of technology providers actively engaged in CPS projects. Based on the outcomes of previous work considering worldwide market segmentation, market figures and competition analysis, opportunities for European stakeholders were then identified along with roadblocks.
The US market offers significant opportunities for European companies and there are major developments underway. However, US companies provide stiff competition in the CPS/IoT sector and currently dominate the area of platforms and the Internet. The report thus considers the current US orientations and support for the CPS/IoT domain (See lower half of Figure 1) using public information complemented by interviews and input from key US proponents such as NIST and NSF. This identified a number of technical areas where there are opportunities for European companies. The business opportunities in the US transportation, energy, manufacturing, health and wellbeing sectors are then considered also identifying entry barriers/roadblocks for European companies. Success stories of European technologies being exploited in the US were sought to identify lessons learnt that can be used to further the success of the European CPS and IoT industry. The report identifies common pitfalls and provides advice on the keys to success of taking European technologies to the US market considering, in particular, the challenges that face smaller companies.

description: The purpose of this study was to fabricate a conductive aligned nanofibrous substrate and evaluate its suitability and cytocompatibility with neural cells for nerve tissue engineering purposes. In order to reach these goals, we first used electrospinning to fabricate single-walled carbon-nanotube (SWCNT) incorporated poly(L-lactic acid) (PLLA) nanofibrous scaffolds and then assessed its cytocompatibility with olfactory ensheathing glial cells (OEC). The plasma treated scaffolds were characterized using scanning electron microscopy and water contact angle. OECs were isolated from olfactory bulb of GFP Sprague-Dawley rats and characterized using OEC specific markers via immunocytochemistry and flow cytometery. The cytocompatibility of the conductive aligned nano-featured scaffold was assessed using microscopy and MTT assay. We indicate that doping of PLLA polymer with SWCNT can augment the aligned nanosized substrate with conductivity, making it favorable for nerve tissue engineering. Our results demonstrated that SWCNT/PLLA composite scaffold promote the adhesion, growth, survival and proliferation of OEC. Regarding the ideal physical, topographical and electrical properties of the scaffold and the neurotrophic and migratory features of the OECs, we suggest this scaffold and the cell/scaffold construct as a promising platform for cell delivery to neural defects in nerve tissue engineering approaches.

description: Strain localization during plastic deformation drastically reduces the shear band stability in metallic glasses, ultimately leading to catastrophic failure. Therefore, improving the plasticity of metallic glasses has been a long-standing goal for several decades. In this regard, nanoglass, a novel type of metallic glass, has been proposed to exhibit differences in short and medium range order at the interfacial regions, which could promote the formation of shear transformation zones. In the present work, by introducing heterogeneities at the nanoscale, both crystalline and amorphous, significant improvements in plasticity are realized in micro-compression tests. Both amorphous and crystalline dispersions resulted in smaller strain bursts during plastic deformation. The yield strength is found to increase significantly in Cu–Zr nanoglasses compared to the corresponding conventional metallic glasses. The reasons for the mechanical behavior and the importance of nanoscale dispersions to tailor the properties is discussed in detail.

description: The early-K star T Cha, a member of the relatively nearby (D ~ 100 pc) epsilon Cha Association, is a relatively "old" (age ~7 Myr) T Tauri star that is still sporadically accreting from an orbiting disk whose inner regions are evidently now being cleared by a close, substellar companion. We report the identification, via analysis of proper motions, serendipitous X-ray imaging spectroscopy, and followup optical spectroscopy, of a new member of the epsilon Cha Association that is very likely a low-mass companion to T Cha at a projected separation of ~38 kAU. The combined X-ray and optical spectroscopy data indicate that the companion, T Cha B (= 2M1155-79), is a weak-lined T Tauri star (wTTS) of spectral type M3 and age ~<10 Myr. The serendipitous X-ray (XMM-Newton) observation of T Cha B, which targeted T Cha, also yields serendipitous detections of two background wTTS in the Chamaeleon cloud complex, including one newly discovered, low-mass member of the Cha cloud pre-MS population. T Cha becomes the third prominent example of a nearby, "old" yet still actively accreting, K-type pre-MS star/disk system (the others being TW Hya and V4046 Sgr) to feature a low-mass companion at very large (12-40 kAU) separation, suggesting that such wide-separation companions may affect the conditions and timescales for planet formation around solar-mass stars.

description: Magnetic refrigeration offers an energy efficient and environmental friendly alternative to conventional vapor‐cooling. However, its adoption depends on materials with tailored magnetic and structural properties. Here a high‐throughput computational workflow for the design of magnetocaloric materials is introduced. Density functional theory calculations are used to screen potential candidates in the family of MM'X (M/M’ = metal, X = main group element) compounds. Out of 274 stable compositions, 46 magnetic compounds are found to stabilize in both an austenite and martensite phase. Following the concept of Curie temperature window, nine compounds are identified as potential candidates with structural transitions, by evaluating and comparing the structural phase transition and magnetic ordering temperatures. Additionally, the use of doping to tailor magnetostructural coupling for both known and newly predicted MM'X compounds is predicted and isostructural substitution as a general approach to engineer magnetocaloric materials is suggested.

description: We present a spectroscopic study of the most massive stars in the young (4 Myr old) stellar cluster LH 95 in the Large Magellanic Cloud. This analysis allows us to complete the census of the stellar population of the system, previously investigated by us down to 0.4 solar masses with deep HST Advanced Camera for Surveys photometry. We perform spectral classification of the five stars in our sample, based on high resolution optical spectroscopy obtained with 2.2m MPG/ESO FEROS. We use complementary ground-based photometry, previously performed by us, to place these stars in the Hertzsprung-Russel diagram. We derive their masses and ages by interpolation from evolutionary models. The average ages and age spread of the most massive stars are found to be in general comparable with those previously derived for the cluster from its low mass PMS stars. We use the masses of the 5 sample stars to extend to the high-mass end the stellar initial mass function of LH 95 previously established by us. We find that the initial mass function follows a Salpeter relation down to the intermediate-mass regime at 2 Msun. The second most massive star in LH 95 shows broad Balmer line emission and infrared excess, which are compatible with a classical Be star. The existence of such a star in the system adds a constrain to the age of the cluster, which is well covered by our age and age spread determinations. The most massive star, a 60-70 Msun O2 giant is found to be younger (<1 Myr) than the rest of the population. Its mass in relation to the total mass of the system does not follow the empirical relation of the maximum stellar mass versus the hosting cluster mass, making LH 95 an exception to the average trend.

description: We propose indium (In) as a possible candidate for observing the permanent electric dipole moment (EDM) arising from the violations of parity (P) and time-reversal (T) symmetries. This atom has been laser cooled and therefore the measurement of its EDM has the potential of improving on the current best EDM limit for a paramagnetic atom which comes from thallium. We report the results of our calculations of the EDM enhancement factor due to the electron EDM and the ratio of the atomic EDM to the electron-nucleus scalar-pseudoscalar (S-PS) interaction coupling constant in In in the framework of the relativistic coupled cluster theory. It might be possible to get new limits for the electron EDM and the S-PS CP violating coupling constant by combining the results of our calculations with the measured value of the EDM of In when it is available. These limits could have important implications for the standard model (SM) of particle physics.

description: Several models for the simulation of photon elastic scattering are quantitatively evaluated with respect to a large collection of experimental data retrieved from the literature. They include models based on the form factor approximation, on S-matrix calculations and on analytical parameterizations; they exploit publicly available data libraries and tabulations of theoretical calculations. Some of these models are currently implemented in general purpose Monte Carlo systems; some have been implemented and evaluated for the first time in this paper for possible use in Monte Carlo particle transport. The analysis mainly concerns the energy range between 5 keV and a few MeV. The validation process identifies the newly implemented model based on second order S-matrix calculations as the one best reproducing experimental measurements. The validation results show that, along with Rayleigh scattering, additional processes, not yet implemented in Geant4 nor in other major Monte Carlo systems, should be taken into account to realistically describe photon elastic scattering with matter above 1 MeV. Evaluations of the computational performance of the various simulation algorithms are reported along with the analysis of their physics capabilities.

description: We investigate the properties of satellite galaxies that surround isolated hosts within the redshift range 0.01 < z < 0.15, using data taken as part of the Galaxy And Mass Assembly survey. Making use of isolation and satellite criteria that take into account stellar mass estimates, we find 3514 isolated galaxies of which 1426 host a total of 2998 satellites. Separating the red and blue populations of satellites and hosts, using colour-mass diagrams, we investigate the radial distribution of satellite galaxies and determine how the red fraction of satellites varies as a function of satellite mass, host mass and the projected distance from their host. Comparing the red fraction of satellites to a control sample of small neighbours at greater projected radii, we show that the increase in red fraction is primarily a function of host mass. The satellite red fraction is about 0.2 higher than the control sample for hosts with 11.0 < log M_* < 11.5, while the red fractions show no difference for hosts with 10.0 < log M_* < 10.5. For the satellites of more massive hosts the red fraction also increases as a function of decreasing projected distance. Our results suggest that the likely main mechanism for the quenching of star formation in satellites hosted by isolated galaxies is strangulation.

description: Despite the broad distribution of several species in Gleicheniaceae in the neotropical region, Diplopterygium is the only genus having a restricted distribution. Species of Gleicheniaceae occupy open (including anthropogenic) habitats and produce large amounts of wind-dispersed propagules – so why does Diplopterygium bancroftii, the only neotropical species in the genus, have a restricted distribution? We investigated if the restricted distribution of Diplopterygium in the Neotropics reflected the absence of suitable areas for the establishment. We used species distribution modelling to identify suitability areas during different periods of the Pleistocene (Last Glacial Maximum and Last Interglacial), the Holocene, and the present. The environmental suitability model at the present time corroborated the current distribution of D. bancroftii, and also evidenced additional suitable potential areas where the species has so far not been recorded, especially in eastern Brazil. In projections of the past, no connectivity was observed between suitable areas in the Andes and eastern Brazil. As neither the dispersal ability nor the absence of suitable areas at the present time or in the past were limiting factors to the range expansion of Diplopterygium, we discuss possible migration barriers and propose a hypothesis for its colonisation history in the Neotropics.
Der Einsatz von Drohnen in bewaffneten Konflikten

description: Drohnen werden in bewaffneten Konflikten seit 2001 zunehmend auch zu Kampfeinsätzen eingesetzt und ermöglichen hierbei eine Kriegsführung aus der Distanz, ohne eigene Soldaten zu gefährden. Gerade mit Blick auf die voranschreitenden technischen Entwicklungen ist davon auszugehen, dass die Anzahl der Kampfeinsätze von Drohnen hierbei noch weiter steigt. Daher stellt sich die Frage, inwieweit Drohnen bei ihrem Einsatz insbesondere dem humanitären Völkerrecht unterfallen und inwieweit sie fähig sind, internationales Recht einzuhalten. In diesem Rahmen ist darauf einzugehen, ob das humanitäre Völkerrecht auf Drohnen anwendbar ist, ob dieses Verbote oder Einschränkungen in Bezug auf Drohnen als Mittel der Kriegsführung trifft und ob sich darüber hinaus Einschränkungen im konkreten Einsatz ergeben. Drones have been used increasingly for combat in armed conflicts since 2001 and they enabled conflict parties to a long-distance warfare without the necessity to directly endanger their own soldiers in the battlefield. Thus, the question at hand is, whether drones fall under the scope of international humanitarian law and to which extent they are able to comply with its provisions. Therefore, this article elaborates, in how far international law, especially humanitarian law, is applicable to drones, if there are any proscriptions or restrictions arising to drones as means of warfare in armed conflict and further, if there are restrictions to be made regarding their concrete use in combat.

Imágenes de la conquista: el encuentro de Cajamarca en Crónica de la Conquista del Perú y en Verdadera Relación de la Conquista del Perú
Creators: name: Guarnieri Calò Carducci, Luigi
Publisher: name: Dipartimento di Lingue, Letterature e Culture moderne - Università di Bologna
Year: 2015
Subjects: Conquista del Perú; fuentes históricas; Atahualpa; Francisco Pizarro; regicidio

description: Las primeras noticias de la conquista del Perú nunca han dejado de ser objeto de estudio y reflexión. Los primeros documentos que describen el Perú y sus riquezas fueron traducidos al italiano muy pronto, poco después de su llegada a España. Algunos de ellos se perdieron, por lo que ahora hay sólo traducciones italianas que los reproducen. El conjunto de estos escritos constituye una fuente muy particul ar de noticias que se difundieron en Europa y que jugaron un papel importante en la construcción de la imagen del Perú en el siglo XVI. Aquí se propone un estudio de dos fuentes de la conquista del Perú a partir de las noticias del acontecimiento de Cajamarca.

El hipotexto figurativo en “Vista del amanecer en el trópico” de Guillermo Cabrera Infante
Creators: name: Ghezzani, Alessandra
Publisher: name: Dipartimento di Lingue, Letterature e Culture moderne - Università di Bologna
Year: 2015
Subjects: Cabrera Infante; Cuban history; ekphrasis; representation; (re)semantization; violence

description: Vista del amanecer en el trópico es la narración de las etapas más importantes de la historia de Cuba. El libro consta de 101 textos, o “viñetas”, algunos de los cuales son descripciones de imágenes (litografías, dibujos, pinturas, fotografías) relativas a personajes o hechos de aquella misma historia. El presente trabajo muestra los resultados de una investigación cuyos objetivos han sido: identificar las “figuras ausentes” (operación que hasta hoy la crítica ha pasado por alto), hallar la fuentes utilizadas por el escritor, ilustrar las estrategias discursivas que subyacen a su ilustración verbal y (re)semantización y, finalmente, evaluar cómo la selección de las imágenes y los modos de su representación contribuyen a expresar la visión de la historia de Cuba que surge del sistema temático y expresivo del libro.

description: Climate change is expected to drive trailing-edge range redistributions of arctic-alpine plant populations, bringing together immigrant plant ecotypes and soil microbial communities associated with already resident ecotypes. The goal of the present study was to assess growth performance and plant–microbe interactions between seedlings and native and foreign microbial communities in ecotypes of the cushion plant Silene acaulis from Europe and North America. Using seed sourced from Colorado, USA, and Ireland we grew Silene seedlings in sterile bulk soil with live inocula added from their own local soil and each other’s soil. We measured above-ground plant growth metrics, and analysed fungal and bacterial community composition using marker gene sequencing and microscopy. Seedlings growing in foreign soil inocula showed significantly greater biomass or shoot length compared to growth in home soil inocula. While seedling root microbiomes were overall convergent with each other compared to source soil inocula, significantly lower filtering of fungal taxa from the soil was observed for seedlings growing in foreign compared to home soil inocula. Foreign plant ecotypes from distant habitats may experience competitively beneficial effects when growing in local soil communities; however, the nature and generality of these interactions requires further analysis.

description: Natur und Kultur beziehungsweise Natur und Mensch sind keine Gegensätze. Sie gehören aus Sicht der Geowissenschaften zum System Erde. Die Diskussion um das „Anthropozän“ als neue erdgeschichtliche Epoche ist Ausdruck dafür. Dennoch sind wir geprägt von der Perspektive des Judentums, des Christentums und des Islam, die den Menschen hervorheben und ihm eine besondere Rolle oder Bedeutung zuschreiben. Daraus entsteht ein Dualismus, der zuweilen auch in Gegensätzliches umschlägt: Natur und Kultur – Gegensätze oder nur zwei Ansichten derselben Medaille?

El fiscal Roa Bastos: escenas del “Cristo paraguayo” y su guerra grande
Creators: name: Tovar, Paco
Publisher: name: Dipartimento di Lingue, Letterature e Culture moderne - Università di Bologna
Year: 2015
Subjects: Paraguay; Solano López; Guerra Grande; Mathias Grünewald; Cándido López

description: En 1993, Augusto Roa Bastos publica El fiscal, novel·∙la donde vuelve a interpretar un episodio de la historia contemporània del Paraguay, remitiendo, desde una perspectiva contemporà nia y frente a la dictadura de Alfredo Stroessner, a su Guerra Grande con las figuras del mariscal Solano López y doña Elisa Lynch. Historia y personajes, manejados al gusto de un tal Félix Moral, toman forma en la escritura de un libreto en cinematogràfic o sin realizar, fiel a los hechos; al describir otra versión de la realidad con destino a una producción fallida sobre el mismo asunto y en tono melodramático. Esa doble configuración, junto a una tercera referencia en clave historiogràfica de R. F. Burto n, tienen su correlato en la pintura de Mathias Grünewald y los cuadros de Cándido López. Todo ello se ofrece como un relato de naturaleza testimonial, dimensión literaria y valor simbólico.

name: Smarandache, Florentin
Publisher: name: arXiv
Year: 2011
Subjects: subject: General Mathematics (math.GM)
subject: FOS: Mathematics
subject: 15-xx

description: In this book for the first time the authors introduce the notion of real neutrosophic complex numbers. Further the new notion of finite complex modulo integers is defined. For every $C(Z_n)$ the complex modulo integer $i_F$ is such that $2F_i = n - 1$. Several algebraic structures on $C(Z_n)$ are introduced and studied. Further the notion of complex neutrosophic modulo integers is introduced. Vector spaces and linear algebras are constructed using these neutrosophic complex modulo integers.

El silencio de las imágenes. Las ilustraciones a Una excursión a los indios ranqueles
Creators: name: Salvioni, Amanda
Publisher: name: Dipartimento di Lingue, Letterature e Culture moderne - Università di Bologna
Year: 2015
Subjects: Argentinian Literature; Indians; Illustrations

description: Una excursión a los indios ranqueles, de L.V. Mansilla, ha sido definido como el único texto de la literatura argentina del siglo XIX que deja emerger las voces de los indígenas. Sin emb a r go, en la historia de su recepción dichas voces fueron silenciadas y el texto fue reducido a su dimensió n anecdótica, editado para la infancia con fines pedagógicos. Paradójicamente, a medida que los protagonistas indígenas enmudecían, se volvían más visibles, convertidos en imágenes, íconos, meras representaciones. El ensayo pretende demostrar que las ilust raciones del texto fueron centrales en ese proceso de desplazamiento y resemantización del texto.

OPTIMIZING INVENTORY MANAGEMENT STRATEGIES TO PREVENT ANTIRETROVIRAL (ARV) MEDICINE SHORTAGES IN HEALTH INSTITUTIONS: A COMPARATIVE ANALYSIS OF CENTRAL MEDICAL STORES AND MEDICAL RESCUE INTERNATIONAL BOTSWANA

description: Abstract  

This study explores the role of inventory management strategies in ensuring the availability of antiretroviral (ARV) medicines in health institutions. It investigates the effectiveness of these systems in addressing shortages by collecting data through interviews with representatives from the Central Medical Stores (CMS) in Gaborone West Industrial and Medical Rescue International Botswana (MRIB). Both institutions utilize distinct inventory management systems, and respondents concur that these systems have been instrumental in eliminating shortages. The occasional shortages encountered are attributed to logistical challenges in order processing rather than inefficiencies in the systems themselves. MRIB, operating under a retail license, faces additional challenges in procuring medicines from warehouse operators, further exacerbating shortages due to supplier acquisition difficulties. To mitigate shortages, both institutions collaborate by requesting supplies from each other, referring patients to other institutions, or temporarily changing medications. Neither CMS nor MRIB maintains buffer stock; instead, CMS undertakes a quantification process six to twelve months prior to ordering, with procurement dependent on whether the medication is sourced locally or internationally. MRIB, with a lead time of one to two days, orders from wholesalers as needed. Although not keeping safety stock reduces operational costs and prevents obsolete stock, implementing a two-bin inventory management system could further eliminate shortages. This system would ensure a continuous supply of medication, thereby minimizing disruptions in ARV provision.
La Guadalupana entre imagen e imaginario: la Virgen popular de Rodolfo Usigli
Creators: name: Di Matteo, Angela
Publisher: name: Dipartimento di Lingue, Letterature e Culture moderne - Università di Bologna
Year: 2015
Subjects: Virgin of Guadalupe; Corona de luz; Rodolfo Usigli; Mexican Theatre; Collective Consciousness

description: El objeto de este estudio es analizar la relación entre la imagen de la Virgen de Guadalupe y el imaginario colectivo mexicano en Corona de luz (1963) de Rodolfo Usigli. La obra trata sobre las presuntas apariciones del Tepeyac y revisa con ironía la tradi ción religiosa y las fuentes históricas. Aunque la Virgen nunca aparece en la escena, el público/lector no pierde el contacto con la imagen milagrosa de la morenita: este continuum entre imagen y texto sólo es posible gracias a la fuerza extraordinaria del icono guadalupano, profundamente arraigado en la identidad cultural mexicana.

description: Solid solution hardening in high entropy alloys was studied for the Cantor alloy using diffusion couples and nanoindentation. We study a continuous variation of the alloying content and directly correlate the nanoindentation hardness to the local composition up to the phase boundary. The composition dependent hardness is analysed using the Labusch model and the more recent Varvenne model. The Labusch model has been fitted to experimental data and confirms Cr as the most potent strengthening element. For comparison of the experimental hardness and the predicted yield strength of the Varvenne model, a concentration-dependent strain-hardening factor is introduced to account for strain hardening during indentation, which leads to a very good agreement between experiment and model. A study of the input parameters of the Varvenne model, performed by atomistic computer simulations, shows no significant effect of fluctuations in the atomic size misfit volumes or in the local shear modulus to the computed yield strength.

Group-theoretical approach to study atomic motion in a laser field

description: Group-theoretical approach is applied to study behavior of lossless two-level atoms in a standing-wave laser field. Due to the recoil effect, the internal and external atomic degrees of freedom become coupled. The internal dynamics is described quantum mechanically in terms of the SU(2) group parameters. The evolution operator is found in an explicit way after solving a single ODE for one of the group parameters. The translational motion in a standing wave is governed by the classical Hamilton equations which are coupled to the SU(2) group equations. It is shown that the full set of equations may be chaotic in some ranges of the control parameters and initial conditions. It means physically that there are regimes of motion with chaotic center-of-mass motion and irregular internal dynamics. It is established that the chaotic regime is specified by the character of oscillations of the group parameter characterizing the mean interaction energy between the atom and the laser field. It is shown that the effect of chaotic walking can be observed in a real experiment with cold atoms crossing a standing-wave laser field.
