Direct visualization of light-driven atomic-scale carrier dynamics in space and time

Electronics is rapidly speeding up. Ultimately, miniaturization will reach atomic dimensions and the switching speed will reach optical frequencies. This ultimate regime of lightwave electronics, where atomic-scale charges are controlled by few-cycle laser fields, holds promise to advance information processing technology from today’s microwave frequencies to the thousand times faster regime of optical light fields. All materials, including dielectrics, semiconductors and molecular crystals, react to such field oscillations with an intricate interplay between atomic-scale charge displacements (polarizations)  and collective carrier motion on the nanometer scale (currents). This entanglement provides a rich set of potential mechanisms for switching and control. However, our ability to eventually realize lightwave electronics, or even to make first steps, will critically depend on our ability to actually measure electronic motion in the relevant environment: within/around atoms. The most fundamental approach would be a direct visualization in space and time. This project, if realized, will offer that: a spatiotemporal recording of electronic motion with sub-atomic spatial resolution and sub-optical-cycle time resolution, i.e. picometers and few-femtoseconds/attoseconds. Drawing on our unique combination of expertise covering electron diffraction and few-cycle laser optics likewise, we will replace the photon pulses of conventional attosecond spectroscopy with freely propagating single-electron pulses at picometer de Broglie wavelength, compressed in time by sculpted laser fields. Stroboscopic diffraction/microscopy will provide, after playback of the image sequence, a direct visualization of fundamental electronic activity in space and time. Profound study of atomic-scale light-matter interaction in simple and complex materials will provide a comprehensive picture of the fundamental physics allowing or limiting the high-speed electronics of the future.
Dynamic transmissions between the U.S. and equity markets in the MENA countries: New evidence from pre- and post-global financial crisis

In this paper we investigate equity returns and volatility co-movement between the U.S. and a group of large Middle East and North African stock markets before and after the global financial crisis in 2008. Our empirical evidence suggests that the pre-crisis relation with the U.S. was weak and negligible, before it jumped to a high level after the crisis. The large diversification in the pre-crisis period was negatively influenced by higher transmissions after the crisis. However, it did not completely disappear during periods of stress. Moreover, there is some evidence that the association with the U.S. has started to revert to its initial low level and therefore, we may conclude that the Middle East and North African equities are important diversifiers for U.S. investors; particularly in the long run.
Automorphisms of central extensions of type I von Neumann algebras

Abstract. Given a von Neumann algebra M we consider the central exten-sion E(M) of M. For type I von Neumann algebras E(M) coincides with thealgebra LS(M) of all locally measurable operators aﬃliated with M. In thiscase we show that an arbitrary automorphism T of E(M) can be decomposedas T = T a ◦ T φ , where T a (x) = axa −1 is an inner automorphism implementedby an element a ∈ E(M), and T φ is a special automorphism generated by anautomorphism φ of the center of E(M). In particular if M is of type I ∞ thenevery band preserving automorphism of E(M) is inner. 1. IntroductionIn the series of paper [1]-[3] we have considered derivations on the algebraLS(M) of locally measurable operators aﬃliated with a von Neumann algebraM, and on various subalgebras of LS(M). A complete description of derivationshas been obtained in the case of von Neumann algebras of type I and III.A comprehensive survey of recent results concerning derivations on various al-gebras of unbounded operators aﬃliated with von Neumann algebras is presentedin [4].It is well-known that properties of derivations on algebras are strongly cor-related with properties of automorphisms of underlying algebras (see e.g. [8]).Algebraic automorphisms of C
SECONDARY SYNCHRONIZATION SIGNAL DETECTION METHOD AND DEVICE

The present invention discloses a method for detecting a secondary synchronization signal, including: calculating a channel estimation compensation value of each sub-carrier of a Secondary Synchronization Signal (SSS) symbol in different Cyclic Prefix (CP) modes; obtaining a coherent accumulative result of even half frames and a coherent accumulative result of odd half frames of each sub-carrier according to the channel estimation compensation value of each sub-carrier of said SSS symbol; generating a SSS sequence; obtaining an index of the SSS sequence corresponding to an over-threshold value of a first round detection, determining indexes composed of the SSS sequence used in a second round detection according to said index, using coherent accumulative results of all the sub-carriers in the even and odd half frames and SSS sequences of all the sub-carriers to obtain an over-threshold value of the second round detection; and obtaining a CP mode, and calculating a cell ID and a radio frame boundary. The present invention further discloses apparatuses for detecting a secondary synchronization signal. The present invention greatly reduces the calculation quantity of the correlation calculation without increasing the additional resource consumption.
Rural migrants’ participation in old-age insurance: a case study of the inter-provincial migrant workers from Sichuan, China

ABSTRACTOld-age pension, a fundamental part of the Chinese social security system, is perceived by the Chinese government as the last support for rural-to-urban migrant workers upon retreating from the labor market. Using survey data collected by the authors, this paper examines a host of factors which influence migrant workers’ participation in the old-age scheme. The result shows that individual characteristics, employment status, attitudes toward old-age support and perception of the old-age pension system significantly differentiate two groups of migrant workers between those that have participated in and their counterparts who have not participated in the old-age pension schemes. Among a number of factors, age, educational attainment, holding labor contract, etc. are found to be significant factors influencing migrants’ behavior participating (or not participating) the available age-pension schemes. Policy implications for how to improve the rate of participation in existing old-age pension schemes a...

Peripartal changes in reticuloruminal pH and temperature in dairy cows differing in the susceptibility to subacute rumen acidosis

The present study aimed to investigate changes in the reticuloruminal pH and temperature dynamics in periparturient dairy cows. Reticuloruminal pH and temperature measurements were conducted from 7 d before until 8 d after parturition using indwelling sensors. Nine Simmental and 4 Brown Swiss dairy cows were fed a close-up total mixed ration (52.5% neutral detergent fiber, 5.68MJ of net energy for lactation per kg of dry matter) with additional 1kg/cow per d concentrate mixture (29.5% neutral detergent fiber and 6.25MJ of net energy for lactation per kg of dry matter), starting from 2 wk before the estimated calving date. Postpartum, all cows had free access to the same close-up diet and were gradually fed increasing amounts of a concentrate-rich total mixed ration for early-lactation cows (32.7% neutral detergent fiber, 7.22MJ of net energy for lactation per kg of dry matter). Data showed depressed reticuloruminal pH early postpartum, but only in the group of cows defined as subacute ruminal acidosis (SARA) susceptible (n=8), which had a higher duration time of pH <5.8 (753±82min/d) compared with SARA-tolerant cows (n=5; 15±6min/d). Also, compared with SARA-tolerant cows (112±91min/d), the SARA-susceptible group showed longer (1,049±75min/d) duration time of pH <6.0. When compared by breed, mean reticuloruminal pH tended to be lower in Simmental (6.16±0.03) than in Brown Swiss cows (6.25±0.05), but no differences were observed in the duration of pH <5.8 between breeds. Simmental cows produced more milk (30.4±1.2kg/d) compared with Brown Swiss cows (27.9±1.3kg/d). Neither total dry matter intake nor milk yield were different between SARA-susceptible and SARA-tolerant groups. However, SARA-tolerant cows consumed greater amounts of the close-up total mixed ration than their SARA-susceptible counterparts, whereas no difference was observed in the intake of the early-lactating total mixed ration between the groups. Reticuloruminal temperature was not affected by breed or SARA susceptibility. Interestingly, the mean reticuloruminal temperature and the time duration of temperature >39.5°C abruptly dropped from d 2 to 1 before calving by 0.35°C and 430min/d, respectively. In conclusion, the strong inter-animal variation in reticuloruminal pH responses suggests the need for more careful monitoring and differentiated feeding management of cows during the transition period, whereby the SARA-susceptible cows may require particular attention regarding feeding management and diet composition. The abrupt decrease in reticuloruminal temperature the day before parturition may enable this noninvasive method as a management tool for prediction of parturition time.

Developing Digital Control System Centrifugal Pumping Unit

Currently, the leading Russian oil companies engaged in the development of automatic control systems (ACS) oil equipment, to improve its efficiency. As an example of an object needed to optimize its work, a centrifugal pumping unit (CPU) can be specified. Frequency actuators provide an opportunity to run CPU in any algorithm, and many industrial controllers, are part of the automatic control system technological process (ACSTP), allow optimizing the operation of the centrifugal pumping unit and help determine the requirements for the development of digital automatic control system for CPU. The development of digital automatic control systems for such a complex nonlinear control object like CPU has several features that should be considered when designing control systems for that object.
Prevalence of<i>L</i><i>actobacillus plantarum</i>and<i>O</i><i>enococcus oeni</i>during spontaneous malolactic fermentation in Patagonian red wines revealed by polymerase chain reaction-denaturing gradient gel electrophoresis with two targeted genes

Background and Aims

Information regarding the composition and dynamics of microbial communities throughout winemaking is always valuable to control the process and contributes to improving the quality of wine. The aims of this work were to analyse the diversity of lactic acid bacteria (LAB) species present during the spontaneous malolactic fermentation (MLF) of Patagonian red wines, and to isolate and identify native LAB species.



Methods and Results

Samples of Merlot and Pinot Noir wines were collected during three vintages at one commercial cellar. Through polymerase chain reaction (PCR)-rpoB/denaturing gradient gel electrophoresis (DGGE), it was possible to identify 15 LAB species and through PCR-16S rRNA V3 region/DGGE, 11 LAB species, during spontaneous MLF of these wines, mostly, Oenococcus oeni and Lactobacillus plantarum. These two species were also largely recovered by culture and analysed by the random amplified polymorphic DNA–PCR technique. Isolates of these two LAB species exhibited considerable genotypic heterogeneity.



Conclusions

The prevalence of O. oeni and Lb. plantarum in all samples suggests that both species are involved in leading the spontaneous MLF of these Patagonian wines. The analysis of the LAB microbiota in wine by PCR-DGGE using two gene regions enabled addition to the number of species that can usually be detected during MLF.



Significance of the Study

The study offered a more complete knowledge of the LAB community present in wines in a cellar in the Argentine Patagonia during the spontaneous MLF. Our findings are particularly relevant, because they contribute to the possibility of designing an MLF starter composed of native strains of Lb. plantarum and O. oeni.
Simulating roman economies. studying the roman economy through computational network modelling and archaeological big data

SIMREC (Simulating Roman Economies) is an inter-disciplinary project that will explore the most hotly debated questions about the Roman economy: was the Roman Imperial trade market equally integrated as nowadays? How important were social networks for structuring this flow of information? It will address two methodological issues currently preventing scholars from answering these questions: limited use of archaeological big data and the lack of quantitative comparisons of complex hypotheses. SIMREC will combine recent advances in computational network science and simulation methods with increasingly available archaeological big datasets, enabled through focused training in these methods at the host institution. In doing so, SIMREC will significantly add to the accumulated knowledge on the Roman economy and will enable for the first time essential quantitative comparisons between the centuries-long Roman record and modern-day economies. The training and research offered by SIMREC will position the experienced researcher (ER) as an expert in network science and computational modelling for the study of the past, and will enable him to significantly influence paradigms and practice in Roman archaeology and history.

Modeling performing arts metadata and relationships in content service for institutions

The modeling of performing arts metadata is considered one of the most challenging problems, since performances add complexities related to events to the classical cultural heritage descriptors associated to physical objects. The most relevant lacks of the present models are related to the modeling of information connected to performers and performances, which are obviously distinguishing aspects of the performing arts and are essential for the preservation of our cultural heritage and literature, such aspects being strongly connected with performing arts. This paper presents the European Collected Library of Artistic Performance (ECLAP) semantic model that has been specifically defined for aggregating and enriching performing arts content coming from several content providers. ECLAP has been set up by the European Commission to play the role of content aggregator for Europeana. The proposed ECLAP semantic model addresses most of the identified problems. The proposed model has been compared with present standards and it is now supported by a graphic tool for user navigation among semantic relationships and Linked Open Data (LOD). The paper also describes the generation of LOD from the ECLAP semantic model and the mapping of ECLAP model to Europeana Data Model (EDM). The experience highlighted that some relevant elements produced, enriched and aggregated by ECLAP cannot be mapped into EDM, while the ECLAP model can address some of the details related to the performing arts which are not at present addressed by the available standards.
Abstract 3853: Predictive and prognostic analysis of KRAS and MSI markers in treatment of urban African American colorectal cancer patients

Proceedings: AACR Annual Meeting 2014; April 5-9, 2014; San Diego, CA

Background: Advancement of molecular analytic techniques has led to the discovery of a number of genetic biomarkers thought to be associated with prognosis and treatment outcomes in colorectal cancer (CRC).

Aim: To analyze response to treatment in a group of CRC patients as a function of their genetic background.

Method: A retrospective chart review of patients diagnosed with CRC from 2010- 2012 at Howard University Hospital was undertaken. African American (AA) patients diagnosed with CRC, the majority of whom received 5-Fluorouracil based chemotherapy, were selected. Data was collected from in-patient and out-patient records. Response to treatment was determined by Response Evaluation Criteria In Solid Tumors (RECIST) criteria from prior radiological investigations. The data was analyzed using Kaplan-Meier survival estimate and log rank test to compare the disease free survival (DFS) in correlation with clinical and genetic markers.

Results: There were 30 AA patients with CRC who received chemotherapy. The average age of the cohort was 59 years, 53 % (n=16) were females and 80% (n=24) of the CRCs were distal. There were 10% (n=3), 23% (n=7), 37% (n=11), and 30% (n=9) patients at stage I, II, III, and IV, respectively. After three years of follow-up, disease free survival was 0.37 (95%CI: 0.14-0.60). Patients with MSI-H (n=3) had worse DFS. Patients with wild-type (WT) KRAS (n=16) had better DFS than mutant KRAS (n=10). The type of chemotherapy received did not affect response.

Conclusions: DFS was worse in patients with a higher stage at the time of diagnosis, as well as, in patients with MSI-H versus MSS. Further study is warranted in AA since CRC patients with MSI-H historically have a better prognosis. DFS was found to be better in patients with WT KRAS, independent of chemotherapeutic regimen. These findings confirm that KRAS mutations negatively affected the prognosis in our study population.

The Unusual Compactness of Viral RNA

We present complementary experimental and computational studies of the relative sizes of equal-length long single-stranded (ss) RNA molecules. Comparison of viral, non-viral, coding and non-coding RNAs of length 2117 nucleotides (nt) shows viral RNA to have among the highest gel-mobilities and smallest hydrodynamic radii in solution. Using graph theoretical tools, we demonstrate that the measured sizes are correlated with the compactness of branching patterns in predicted secondary structure ensembles. Compactness is determined by the number and relative positions of 3-helix junctions, and is highly sensitive to the presence of rare higher-order (4 or more helix) junctions. RNAs from spherical viruses possess greater numbers of higher-order junctions than random sequences or those from non-spherical viruses. The importance of secondary structure topography as a determinant of global RNA size, and implications of compactness for viral assembly will be discussed.The accompanying native gel-electrophoresis image comparing RNAs of identical length shows they have significantly different hydrodynamic properties. Lane 1 contains the viral RNA, mutated viral sequences are in lanes 2-4, and lanes 5-9 show equal-length transcripts from arbitrary sections of the yeast genome. Lane 6 shows that RNAs with different sequences although mixed before electrophoresis are separable.View Large Image | View Hi-Res Image | Download PowerPoint Slide
