Stability of a Floquet Bose-Einstein condensate in a one-dimensional optical lattice

Motivated by recent experimental observations (C.V. Parker {\it et al.}, Nature Physics, {\bf 9}, 769 (2013)), we analyze the stability of a Bose-Einstein condensate (BEC) in a one-dimensional lattice subjected to periodic shaking. In such a system there is no thermodynamic ground state, but there may be a long-lived steady-state, described as an eigenstate of a "Floquet Hamiltonian". We calculate how scattering processes lead to a decay of the Floquet state. We map out the phase diagram of the system and find regions where the BEC is stable and regions where the BEC is unstable against atomic collisions. We show that Parker et al. perform their experiment in the stable region, which accounts for the long life-time of the condensate ($\sim$ 1 second). We also estimate the scattering rate of the bosons in the region where the BEC is unstable.
Non-linear response of buckled beams to 1:1 and 3:1 internal resonances

Abstract The non-linear response of a buckled beam to a primary resonance of its first vibration mode in the presence of internal resonances is investigated. We consider a one-to-one internal resonance between the first and second vibration modes and a three-to-one internal resonance between the first and third vibration modes. The method of multiple scales is used to directly attack the governing integral–partial–differential equation and associated boundary conditions and obtain four first-order ordinary-differential equations (ODEs) governing modulation of the amplitudes and phase angles of the interacting modes involved via internal resonance. The modulation equations show that the interacting modes are non-linearly coupled. An approximate second-order solution for the response is obtained. The equilibrium solutions of the modulation equations are obtained and their stability is investigated. Frequency–response curves are presented when one of the interacting modes is directly excited by a primary excitation. To investigate the global dynamics of the system, we use the Galerkin procedure and develop a multi-mode reduced-order model that consists of temporal non-linearly coupled ODEs. The reduced-order model is then numerically integrated using long-time integration and a shooting method. Time history, fast Fourier transforms (FFT), and Poincare sections are presented. We show period doubling bifurcations leading to chaos and a chaotically amplitude-modulated response.
RIDING CROP APPARATUS FOR STRIKING A HORSE

A riding crop for striking a horse having a shaft formed of a rigid interior pole having a resilient exterior cover and a unitary popper is defined by an elongated body. The riding crop additionally includes a handle covering or positioned adjacent to the proximal end of the shaft. The popper is positioned over or adjacent to the distal end of the shaft, with the shaft extending between the handle and the popper. The handle provides a surface that allows a user to hold the riding crop and the popper is the portion of the riding crop intended to contact a horse. The popper is defined by an oblong, bulbous member which is formed as a unitary one-piece structure and which includes an aperture that extends longitudinally through the popper from the end which forms the distal end to the shaft
Ecological diversity of land vertebrates through the largest extinction in earth history

Contemporary Earth’s ecosystems are threatened by accelerating extinction rates, but their responses to biodiversity losses are not detectable on short time scales. However, many large-scale biodiversity crises, or ‘mass extinctions’, occurred in the past and played a fundamental role in evolution. For instance, modern-style ecosystems originated from the worst biodiversity crisis in Earth history (PTME) at the Permian-Triassic boundary (~252 million years ago). The PTME killed over 70% of vertebrate species and created opportunities for new groups to diversify. After the extinction, Triassic land vertebrate assemblages were transformed, and new species diversified in ecological roles that were unexploited in Permian ecosystems. This suggests that extinctions may change the evolutionary trajectory of ecosystems and increase ecological complexity. Nevertheless, the ecological impacts of mass extinctions on ecosystems are still poorly understood. For the first time, this project critically investigates how the ecological structure and composition of land ecosystems changed across the PTME and its connection to biodiversity recovery. We will target the fossil record of exceptionally preserved Permian-Triassic ecosystems, alongside new field data from critical, but poorly sampled time intervals. Using a suite of novel approaches modified from modern ecology, we will quantify changes in ecological diversity, richness and stability of land ecosystems and major vertebrate groups. These patterns will be used to understand what factors drive biodiversity and the evolution of ecosystems during and after times of crisis. Through a comprehensive training and knowledge exchange programme, the experienced researcher and hosts will bring together and integrate their expertise in palaeontology, biology, quantitative techniques, and macroevolution to deliver this timely, innovative, and interdisciplinary project that will address fundamental ecological questions.
Du couvent au collège : relations, circulations et conflits entre San Pablo et San Gregorio à Valladolid

Cet article vise à explorer la relation entre deux importantes institutions dominicaines basées à Valladolid. Toutes deux ont joué un rôle clé dans la promotion et la consolidation de la réforme de l'Ordre en Castille à la fin du xve siècle. La fondation du Colegio de San Gregorio en 1487 par Alonso de Burgos, frère dominicain et évêque de Palencia, sur des terres cédées par le couvent voisin de San Pablo, marque le début de ces relations tortueuses. Cependant, le souhait du prélat, selon les statuts du Collège, était de garantir une vie harmonieuse entre les deux communautés. L'article analyse comment la disposition du collège a été conçue en fonction du passage des frères du couvent au collège, pour suivre des cours universitaires, et vice versa.
Analyzing and Enforcing Security Mechanisms on Requirements Specifications

[Context and motivation] Security mechanisms, such as firewalls and encryption, operationalize security requirements, such as confidentiality and integrity. [Question/problem] Although previous work has pointed out that the application of a security mechanism affects system specifications, there is no systematic approach to describe and analyze this impact. [Principal ideas/results] In this paper, we investigate more than 40 security mechanisms that are well documented in security pattern repositories in order to better understand what they are and how they function. [Contribution] Based on this study, we propose a conceptual model for security mechanisms, and evaluate this model against 20 security mechanisms. Using the conceptual model, we provide a systematic process for analyzing and enforcing security mechanisms on system requirements. We also develop a prototype tool to facilitate the application and evaluation of our approach.

Membrane-Associated Glucose-Methanol-Choline Oxidoreductase Family Enzymes PhcC and PhcD Are Essential for Enantioselective Catabolism of Dehydrodiconiferyl Alcohol

ABSTRACT Sphingobium sp. strain SYK-6 is able to degrade various lignin-derived biaryls, including a phenylcoumaran-type compound, dehydrodiconiferyl alcohol (DCA). In SYK-6 cells, the alcohol group of the B-ring side chain of DCA is initially oxidized to the carboxyl group to generate 3-(2-(4-hydroxy-3-methoxyphenyl)-3-(hydroxymethyl)-7-methoxy-2,3-dihydrobenzofuran-5-yl) acrylic acid (DCA-C). Next, the alcohol group of the A-ring side chain of DCA-C is oxidized to the carboxyl group, and then the resulting metabolite is catabolized through vanillin and 5-formylferulate. In this study, the genes involved in the conversion of DCA-C were identified and characterized. The DCA-C oxidation activities in SYK-6 were enhanced in the presence of flavin adenine dinucleotide and an artificial electron acceptor and were induced ca. 1.6-fold when the cells were grown with DCA. Based on these observations, SLG_09480 ( phcC ) and SLG_09500 ( phcD ), encoding glucose-methanol-choline oxidoreductase family proteins, were presumed to encode DCA-C oxidases. Analyses of phcC and phcD mutants indicated that PhcC and PhcD are essential for the conversion of (+)-DCA-C and (−)-DCA-C, respectively. When phcC and phcD were expressed in SYK-6 and Escherichia coli , the gene products were mainly observed in their membrane fractions. The membrane fractions of E. coli that expressed phcC and phcD catalyzed the specific conversion of DCA-C into the corresponding carboxyl derivatives. In the oxidation of DCA-C, PhcC and PhcD effectively utilized ubiquinone derivatives as electron acceptors. Furthermore, the transcription of a putative cytochrome c gene was significantly induced in SYK-6 grown with DCA. The DCA-C oxidation catalyzed by membrane-associated PhcC and PhcD appears to be coupled to the respiratory chain.

Homo mimeticus: theory and criticism

Mimesis is one of the most influential concepts in Western thought. Originally invoked to define humans as the “most imitative” creatures in classical antiquity, mimesis (imitation) has recently been at the centre of theoretical debates in the humanities, social sciences, and the neurosciences concerning the role of “mimicry,” “identification,” “contagion,” and “mirror neurons” in the formation of subjectivity. And yet, despite the growing confirmations that imitation is constitutive of human behaviour, mimesis still tends to be confined to the sphere of realistic representation. The HOM project combines approaches that are usually split in different areas of disciplinary specialization to provide a correction to this tendency.

Conceived as a trilogy situated at the crossroads between literary criticism, cinema studies, and critical theory, HOM’s outcomes will result in two monographs and accompanying articles that explore the aesthetic, affective, and conceptual implications of the mimetic faculty. The first, radically reframes a major proponent of anti-mimetic aesthetics in modern literature, Oscar Wilde, by looking back to the classical foundations of theatrical mimesis that inform his corpus; the second considers the material effects of virtual simulation by looking ahead to new digital media via contemporary science-fiction films; and the third establishes an interdisciplinary dialogue between philosophical accounts of mimesis and recent discoveries in the neurosciences. Together, these new perspectives on homo mimeticus reconsider the aesthetic foundations of a major literary author, open up a new line of inquiry in film studies, and steer philosophical debates on mimesis in new interdisciplinary directions.
Onset of Convective Rainfall During Gradual Late Miocene Rise of the Central Andes

Separated About Lift The uplift history of the Andes of South America is a contentious issue, with the two main hypotheses polarizing from rapid growth between roughly 10 and 7 million years ago to more gradual elevation over most of the past 40 million years. The oxygen isotopic composition of soil carbonates has been used as a proxy for altitude and to measure the timing of uplift. Poulsen et al. (p. 490 , published online 1 April) applied a global atmospheric general circulation model to show that the oxygen isotopic composition changes seen in carbonates formed in the late Miocene were driven more by changes in the amount of precipitation than by the altitude at which the precipitation forms. Consequently, it seems that oxygen isotopes are not a reliable paleoaltimeter, and Andean uplift may not have been as precipitate as thought.
Transient deformation of karst aquifers due to seasonal and multiyear groundwater variations observed by GPS in southern Apennines (Italy)

We present GPS, hydrological, and GRACE (Gravity Recovery and Climate Experiment) observations in southern Apennines (Italy) pointing to a previously unnoticed response of the solid Earth to hydrological processes. Transient patterns in GPS horizontal time series near to large karst aquifers are controlled by seasonal and interannual phases of groundwater recharge/discharge of karst aquifers, modulating the extensional similar to 3 mm/yr strain within the tectonically active Apennines. We suggest that transient signals are produced, below the saturation level of the aquifers and above a poorly constrained depth in the shallow crust, by time-dependent opening of subvertical, fluid-filled, conductive fractures. We ascribe this process to the immature karstification and intense tectonic fracturing, favoring slow groundwater circulation, and to multiyear variations of the water table elevation, influenced by variable seasonal recharge. The vertical component displays seasonal and multiyear signals more homogeneously distributed in space and closely correlated with estimates of total water storage from GRACE, reflecting the elastic response of the lithosphere to variations of surface water loads. The different sensitivities of vertical and horizontal components to the hydrologically induced deformation processes allow us to spatially and temporally resolve the different phases of the water cycle, from maximum hydrological loading at the surface to maximum hydrostatic pressure beneath karst aquifers. Finally, we suggest that transient deformation signals in the geodetic series of the Apennines are correlated to large-scale climatic patterns (Northern Atlantic Oscillation) through their influence on precipitation variability and trends at the regional scale.
Mould production technology for internal combustion engine blocks castings

“The aim of the project is to implement an integrated technology for the production of specialised foundry pressurised moulds for the production of internal combustion engine blocks for the automotive industry. One of the key elements of the above-mentioned integrated technology is the technology of making sockets for thermocouple sensors in a housing of deep (40 cm) sockets while maintaining a narrow dimensional tolerance, i.e. > 0,01 mm (to date tolerance not exceeding 0,1 mm). This technology, in the form of a technological line for honing (working holes for thermopolar sensors) was filed for a patent claim as an invention in October 2015 BC. “Honing Machine” under number P.414371. The main objective of the project will therefore be to introduce a new generation of foundry pressurised moulds on the domestic and international market as a product for the foundry industry focused on production for the automotive industry. “
Enhancing brain function and cognition via artificial entrainment of neural oscillations

Neural oscillations are ubiquitous in the human brain and have been implicated in diverse cognitive functions to support both neural communication and plasticity. Their functional relevance is further supported by a large number of studies linking various cognitive deficits (e.g., attention deficit hyperactivity disorder, ADHD) with abnormal neural oscillations. However, this field of research faces two important problems: First, there is only correlative, but no causal evidence linking cognitive deficits to abnormal neural oscillations in humans. Second, there is virtually no theory-driven mechanistic approach that generates insights into how oscillations within and across neural networks are linked to human behavior. In this project, I propose to take decisive steps to provide a long-needed neurophysiological characterization—via (1) computational modelling, (2) electrophysiological measures, and (3) novel non-invasive manipulations of cortical rhythms—on how neural oscillations contribute to two types of cognitive processes that are fundamental for many aspects of human behavior: attention and short-term memory. I will go a step further by demonstrating that it is possible to augment performance in these cognitive functions with the design of non-invasive brain stimulation protocols individually tailored to the theory-driven neurocomputational characterizations and electrophysiological signatures of each individual. This will result in the applied goal of deriving new neuro-computational assays that can detect deviant network interactions causally related to cognitive functions, which is key for then renormalizing those functions in neuropsychological conditions such as ADHD. Thus, if successful, my proposed work will ultimately result in novel, low-cost, and painless non-invasive neural interventions for a wide range of neuropsychological disorders tied to abnormal neural oscillations.
Transit time of CME/shock associated with four major geo-effective CMEs in solar cycle 24

Abstract The kinematics of coronal mass ejection (CME) in the interplanetary medium is very important in the concept of space-weather. Main aim of this paper is to study the propagation of four major geo-effective CMEs and their associated shocks observed in solar cycle 24. The arrival of interplanetary shocks and CMEs of these events near the Earth is seen from the ACE/wind in situ data available in OMNI data base. The CMEs considered in this study have a wide range of initial speeds 500–1900 km/s in the LASCO field of view, comprising of two slow CMEs ( V  ∼ 500 km/s), one fast CME ( V  ∼ 1800 km/s) and one moderate speed CME ( V  ∼ 800 km/s). The observed transit time of these events are compared with transit time estimated using the empirical shock arrival model (ESA). Especially, we utilize (i) different acceleration – speed equations reported in the literature from the observations made in the last few decades and (ii) various acceleration cessation distances ( Acd ) In addition, we compared the estimated and observed transit time with that from the Drag Based Model (DBM). From the result of this analysis, we demonstrated that each CME behaves in its own way in the interplanetary medium and their propagation is governed by the CME initial speed, interplanetary acceleration and acceleration cessation distances. In the present paper, we found (i) which acceleration equation is better for the transit time calculations (ii) importance of the CME acceleration cessation distances (iii) reducing the transit time error in CME forecasting. Based on these results and on Zhao and Dryer (2014) review (that included physics-based models), the realistic statistics should be based on real-time studies, not on post-mortem case studies.
Two-Dimensional Monte Carlo Simulation of DGSOI MOSFET Misalignment

In this paper, we investigate the gate misalignment effects in a 10-nm double-gate silicon-on-insulator MOSFET transistor with a 2-D Monte Carlo simulator. Quantum effects, which are of special relevance in such devices, are taken into account by using the multivalley effective conduction-band-edge method. Different gate misalignment configurations have been considered to study the impact on device performance, finding a current improvement when the gate misalignment increases the source-gate overlapping. Moreover, our results show that a 20% gate misalignment can be assumed for a drain current deviation smaller than 10%. Finally, the validity of the obtained results was assessed with a set of simulations for devices that have different gate lengths, silicon thicknesses, and oxide thicknesses.
