Smart Libraries

Can the smart city provide a new perspective for public and academic libraries? How does the smart city impact the libraries as cultural and scientific assets? And how can libraries contribute to the development of the smart city? An overview of recent library models, like the learning center or the green library, reveals affinities with the concept of the smart city, especially regarding the central role of information and the integration of technology, people, and institutions. From this observation, the paper develops the outline of a new concept of the smart library, which can be described in four dimensions, i.e., smart services, smart people, smart place, and smart governance. However, the smart library concept does not constitute a unique model or project, but a process, a way of how to get things done, that is less linear, less structured, and more creative and innovative. Also, smartness may not be a solution for all library problems.
The young intermediate-mass stellar object AFGL 490 – A disk surrounded by a cold envelope

AFGL 490 is a key target of the class of deeply embedded intermediate-mass young stellar objects in a transition stage to Herbig Be stars (L = 2.2-4.0 × 10 3 L� ). In this paper, we present a comprehensive set of single-dish line data which characterize the envelope of the source. In addition, observations of CS J = 2→1 and the corresponding continuum at 97.98 GHz have been obtained with the Plateau de Bure (PdB) interferometer, which are sensitive to the small-scale structure around the stellar source. The PdB line data show a bar-like elongated gas structure of 22000 AU × 6000 AU size with a position angle of ≈-45 ◦ . This bar represents the flattened inner envelope surrounding a disk-like structure (radius ≤500 AU) for which we find evidence very close to the young B star. Due to strong (self-)absorption in the velocity range vlsr = -12.5 . -15 km s −1 , only the outer line wings can be used to study the gas motion. Maps of the integrated red and blue line wing emission show two well-separated gas blobs around AFGL 490, which are interpreted as a disk. The 3 mm continuum interferometer map shows a point source at the position of AFGL 490 with a flux of 240 mJy. This flux translates into a total mass of 3-6 Mof the disk which is comparable to the stellar mass of about 8 M� . This configuration is unstable and will disappear in 10 3 -10 4 years due to gravitational instabilities. Photometric data from ISOPHOT and spectroscopic data from ISO-SWS have been obtained. Together with submillimetre continuum data a very complete spectral energy distribution of the envelope could be compiled. Analysis of the data shows that the central region of AFGL 490 has a steeper density gradient compared with the outer molecular envelope. All data clearly point to a low temperature (25-35 K) of this envelope. To determine the chemical state of the object, we determined the abundances of 13 molecules towards AFGL 490. The molecular line and ISO-SWS data are used to derive the gas-solid abundance ratios for H2O, CO, and CO2. The chemical results, such as the relatively low gas-to-solid ratios and the low CH3OH excitation, emphasize the presence of a cold molecular envelope. We found evidence for other outflow systems in the envelope around AFGL 490. Red-shifted and blue-shifted gas blobs with a separation of about 20000 AU were detected. Their centre is located roughly 3 �� to the south of AFGL 490, and their morphology implies that a deeply embedded low-mass object drives a jet which enters the denser envelope material at such a large distance. Two further outflow systems in the close neighbourhood of AFGL 490 could be identified. All these data point to the formation of a group of low-mass stars around AFGL 490. It is very remarkable that these outflows do not influence the global physical and chemical structure of the envelope.
Re-Re-Reply to 'The Impact of Microcredit on the Poor in Bangladesh: Revisiting the Evidence'

“The Impact of Microcredit on the Poor in Bangladesh: Revisiting the Evidence,” by David Roodman and Jonathan Morduch (2014) is the most recent of a sequence of papers and postings that seeks to refute the findings of the Pitt and Khandker (1998) article “The Impact of Group-Based Credit on Poor Households in Bangladesh: Does the Gender of Participants Matter? ” that microcredit for women had significant, favorable effects on poverty reduction. This response paper refutes the claims of Roodman and Morduch that were not addressed in the earlier World Bank working paper of Pitt and Khandker (2012). This response paper, like the Pitt and Khandker (2012) paper and others that preceeded it, shows that many of the Roodman and Morduch claims are based on a flawed econometric understanding and a lack of due diligence in formulating and interpreting statistical models.
The Interaction of Wings in Different Flight Modes of a Dragonfly

Flow fields around the wings of a live dragonfly (Pantala Flavenscens) have been studied using different visualization techniques. Flapping flight and tandem wing configuration are of particular interests for applications on micro air vehicles aimed to achieve similar flight agility as that of a dragonfly. High speed video recordings were used to determine core values of the flapping exhibited by the tethered specimen. These frames were also used to confirm wing alignment on PIV frames. A novel smoke visualization technique has been used to obtain base data for comparison with in phase flapping PIV results. The tethered dragonfly exhibited different flapping patterns which resulted in four distinct flow field structures; however, some were achieved by different flapping modes. In phase flapping is particularly interesting as it is considered a flight mode of the dragonfly when extra thrust are needed for maneuvering or take off. In some cases out of phase flapping generated two separate air streams that supposedly give more stability to the emerging dragonfly. This kind of flow structure has not been comprehensively studied yet. Experiments have been done in still air so the results are not affected by a mainstream flow like in the case of wind tunnel experiments. The general description of the flow fields found is discussed and some points were compared with earlier studies to support the development of tandem wing micro air vehicles.
Research of electro-explosive iron powder using the hydrolytic adsorption method

This work is aimed at solving the urgent problem associated with the diagnostic and forecasting of functional characteristics of finely dispersed materials. It considers the effect of primary acid-base center characteristics on the wetting process. The research of hydrolytic adsorption is carried out using the nano-dimensional iron powders. The powders were obtained by applying the method of electric explosion of conductors, after that they were passivated under different conditions. The identification of composition and structure of the passivating oxide film was carried out applying the method of transmission electron microscopy and X-ray diffraction analysis. The paper also describes the inhibition mechanism of hydrolytic adsorption on ferrioxide compounds with different composition and structure. The inhibition mechanism explains the hydrophilic / hydrophobic behavior of oxide compounds. The material of this article can be useful for its implementation in industrial, research and school laboratories.
Living without mitochondria : spermatozoa and spermatogenesis in two species of Urodasys (Gastrotricha, Macrodasyida) from dysoxic sediments

Abstract. The spermatozoa of two species of Macrodasyida (Gastrotricha), Urodasys anorektoxys and U. acanthostylis, show an ultrastructural organization diverging from one another and from other gastrotrichs: their main peculiarity is in the absence of mitochondria. In U. anorektoxys, the acrosome is a long, twisted column inserted into the nucleus, which is basally cylindrical, and the flagellum shows rows of peculiar, large globules parallel to the axonemal doublets. In U. acanthostylis, the acrosome is completely cork-screwed and surrounds the nucleus, and the tail shows columnar accessory fibers. At present, the absence of mitochondria in the mature sperm, and the peculiar fingerprint aspect of condensed chromatin are the only traits shared by the two species. The features of the spermatozoa of these two species of Urodasys widen the range of different models of gastrotrich spermatozoa, and place the genus in a peculiar position, from the spermatological point of view, within the Macrodasyida. The loss of mitochondria in mature spermatozoa is possibly related to either the dysoxic habitat of the two species or a peculiar fertilization mechanism.
Using numerical continuation to study “ large ” amplitude solutions to the 2 : 1 forced complex Ginzburg – Landau equation October 7 , 2014

Thus, steady state solutions depend on the parameter μ. The idea behind continuation is to try to use information about known solutions to find “nearby” solutions. This is possible by the implicit function theorem. For example, to find steady state solutions to equation (1.1), we look for zeros of the function fpu;μq :“ u2 ́ μ. Suppose that we know the exact solution u “ u ̊ for a fixed μ “ μ ̊; then it must be true that fpu ̊;μ ̊q “ 0. One can easily check that fupu ̊;μ ̊q ‰ 0 provided u ‰ 0; thus, by the implicit function theorem, there exists function gpμq for μ near μ ̊ so that fpgpμq;μq “ 0. The curve gpμq is the curve of equilibria in parameter space; see Figure 1. This means that to perform numerical continuation we need a method of finding zeros of functions.
Why Do People Trade?

Besides trading to save, manage risk, and speculate, people trade simply because they find it entertaining. In a survey of 1,300 German discount brokerage clients, respondents who indicate that they “enjoy investing” and “enjoy risky propositions” trade twice as much as their peers. In contrast, standard motives for trading such as saving and rebalancing explain little of the variation in trading activity across investors. Entertainment appears to be a straightforward explanation for why some people trade much more than others and why active traders underperform their peers after transaction costs.
D C ] 1 6 M ay 2 01 8 Loom : ExploitingWeight and Activation Precisions to Accelerate Convolutional Neural Networks

Loom (LM), a hardware inference accelerator for Convolutional Neural Networks (CNNs) is presented. In LM every bit of data precision that can be saved translates to proportional performance gains. Specifically, for convolutional layers LM’s execution time scales inversely proportionallywith the precisions of both weights and activations. For fully-connected layers LM’s performance scales inversely proportionally with the precision of the weights. LM targets areaand bandwidth-constrained System-on-a-Chip designs such as those found on mobile devices that cannot afford the multimegabyte buffers that would be needed to store each layer on-chip. Accordingly, given a data bandwidth budget, LM boosts energy efficiency and performance over an equivalent bit-parallel accelerator. For both weights and activations LM can exploit profilederived per layer precisions. However, at runtime LM further trims activation precisions at a much smaller than a layer granularity. Moreover, it can naturally exploit weight precision variability at a smaller granularity than a layer. On average, across several image classification CNNs and for a configuration that can perform the equivalent of 128 16b × 16b multiply-accumulate operations per cycle LM outperforms a state-of-the-art bit-parallel accelerator [1] by 4.38× without any loss in accuracy while being 3.54× more energy efficient. LM can trade-off accuracy for additional improvements in execution performance and energy efficiency and compares favorably to an accelerator that targeted only activation precisions. We also study 2and 4-bit LLM variants and find the the 2-bit per cycle variant is the most energy efficient.
Ecosystem wicks: Woodland trees enhance water infiltration in a fragmented agricultural landscape in eastern Australia

Since European settlement, Eucalyptus box woodlands have been substantially modified by agricultural practices, and in many areas in southern Australia are now restricted to scattered or clumped trees. We report here on a study to examine the impact of trees on water flow (infiltration) in an agricultural landscape with substantial areas of extant native vegetation. We examined infiltration through coarse- and fine-textured soils within four landscape strata, the zones below Eucalyptus melliodora and Callitris glaucophylla canopies, the intertree zone dominated by perennial grasses and a landscape homogenized by cultivation and dominated by annual crops. We measured sorptivity, the early phase of water flow, and steady-state infiltration with disc permeameters at two supply potentials. These different potentials enabled us to separate infiltration into (i) flow through large (biopores) and small pores and (ii) flow through small pores only where biopores are prevented from conducting water. On the fine-textured soils, both sorptivity and steady-state infiltration were significantly greater (approximately fivefold) under the timbered strata compared with the grassy slopes or cultivation. Differences were attributable to the greater proportion of macropores below the tree canopies compared with the nontimbered strata. The lack of a significant difference on the coarse-textured soils, despite their macropore status, was attributed to differences in surface litter and plant cover, which would maintain continuous macropores at the surface and thus conduct large amounts of water. The tendency of slopes covered by cryptogamic crusts and grasses to shed run-off and for the trees to absorb substantial quantities of water reinforced the important ecological service provided by trees, which moderates large run-off events and captures small amounts of water leaking from the grassy patches. In the absence of these 'ecosystem wicks', run-off would find its way into regional groundwater and contribute to rising salinity.

Functional characterization of ent-kaurene oxidase, MtKO, from Montanoa tomentosa (Zoapatle)

Kaurene oxidases are P450 proteins that catalyze the conversion of ent-kaurene into kaurenoic acid, the final enzymatic product with a wide range of pharmacological properties. We describe the functional characterization of an ent-kaurene oxidase (EC 1.14.13.78) isolated from Montanoa tomentosa after heterologous expression in Saccharomyces cerevisiae, as well as the detection of the enzymatic activity in the plant itself. In the presence of NADPH and FAD, the microsomal fraction from transformed INVSc1 cells, ent-kaurene produced ent-kaurenoic acid, which was confirmed by GC-MS analyses. The kinetic parameters for ent-kaurene using 0.5 mg of microsomal protein were Km app= 80.63±1.2 μM and V max app= 31.80±1.8 μmol-1mg-1h-1. Optimal temperature and pH were 30°C and 7.6, respectively. Similar kinetic parameters were observed when leaf microsomes from M. tomentosa were assayed under the same conditions as for yeast microsomes. This result strongly suggests that ent-kaurene oxidase activity is present in leaf microsomes. The enzymatic activity was competitively inhibited by paclobutrazol, with IC50=43.9 μM, implying that MtKO is resistant to inhibition by azolic-type compounds. This study confirmed the biochemical detection of ent-kaurene oxidase activity in the plant, and the heterologous functionality of a cDNA with an ent-kaurene oxidase identity from M. tomentosa (zoapatle).
Self-reinforcing graphene coatings on 3D printed elastomers for flexible radio frequency antennas and strain sensors

The emergence of the Internet of Things (IoT) necessitates the development of electronic components with various form factors and mechanical properties. 3D printing is an effective tool to realize objects with arbitrary form factors. Various 3D printable materials have recently been commercialized; among them, stretchable materials are particularly useful in the IoT because they enable adaptability in the dimensional change of the electronics. Most of these stretchable materials are, however, not electrically conductive; conductive coating can enable the functionality. Here, we propose a self-reinforcing conductive coating strategy, which reduced graphene oxide (RGO) self-assembles to wrap graphene nanoflakes (GNF) as a conductive binder that can also achieve mechanical integrity. The conductivity of the GNF-RGO coating reaches 4.47 × 104 S m−1. To demonstrate the potential applications of the GNF-RGO coating, applying the coating on 3D printed porous elastomers enabled flexible radio frequency (RF) antennas and strain sensors. The RF antenna shows high radiation efficiency and maintains excellent performance under bending conditions. The coating also produces a strain sensor with a gauge factor of ∼13 up to 40% of strain. We foresee that the electrically conductive GNF-RGO composite coating can provide versatile functionalization strategy in flexible electronics and in wearable biomedical devices.
Quantum-Chemical Design of Molecular Quantum-Dot Cellular Automata (QCA): A New Approach from Frontier Molecular Orbitals

Recently, research and development of next-generation devices have been very active (1). Quantum-dot cellular automata (QCA) (2) which is constructed frommany quantum dot cells (QDC, Fig. 1) is one of such new-generation devices. The QCAdevices such as amajority logic gate and a signal transmissionwire (Fig. 2) are expected to achieve a dramatic saving of energy and an increase in processing speed of computing since these devices are free from a current flow. Successful operations of several QCA devices have been already demonstrated (3; 4). However, for improvement in operation temperature and size of the QCA devices, the idea of molecular quantum-dot cellular automata (molecular QCA) devices (5), in which a QDC constructed from small metallic dots is replaced by a single molecule, was proposed. Toward the experimental operation of molecular QCA devices, syntheses of tetranuclear complexes (6–10) and simplified dinuclear complexes (11; 12), and single-molecule observation of the dinuclear complexes (13–16) have been paid attention. However, the capacity of molecular QCA devices for molecular computing is still not clear.
Role of the Thiol Redox Control in Myocardial Ischemia-Reperfusion Injury

In our experiments, we have been used isolated working hearts to study the role of redox-signaling mechanisms in cardioprotection. In the first part of our research, we studied the potential role of the peroxiredoxin 6 (Prdx6) in I-R induced injury. Prdx6 is a novel peroxidase enzyme belonging to the Prdx family, which in mammals contains five more peroxiredoxins (Prdx1–Prdx5). Like glutathione peroxidase (GSHPx) and catalase, Prdx6 possesses H2O2scavenging activities, and, like the former, it also removes hydroperoxides. Since significant amounts of catalase and GSHPx are present in the heart contributing toward the attenuation of H2O2 and hydroperoxides formed during I-R injury and thereby providing cardioprotection, we investigated whether Prdx6 also has any role in this process. In this study we used Prdx6/ mice to assess the role of Prdx6 in ischemic injury. Western blot analysis revealed the absence of any Prdx activity in the Prdx6 _ / _
The implementation of elder-care in France and Sweden: a macro and micro perspective

ABSTRACT This paper presents results from a comparative project on the implementation of elder-care in France and Sweden. The transition to requiring care is understood as a process, and elder-care is seen as a part of a more general organisation of social care that reflects different welfare traditions. An overview of elder-care on the institutional level in the two countries is supplemented by case studies from the perspective of older people which identify ways of co-operation between actors, such as public eldercare providers, family members and help provided by profit and non-profit organisations. The interviews include approximately 20 older persons in each country as well as a small number of administrators and adult children. The study sheds light on how policies are implemented on the local level and puts the focus on who actually does what and when for older persons with care needs. The different roles played by the state, the family, the market and civil society are examined. Family members in France take on a more active role both as co-ordinators of care and as actual caregivers. The study shows that gender and social class remain associated with caring but that such differences are much larger in France than in Sweden.
