description: We use AdS/QCD holographic Distributions Amplitudes for the vector mesons $ρ$ and $K^*$ in order to predict the radiative decays $B \to ργ$ and $B \to K^* γ$ as well as the semileptonic decays $B \to ρl ν$ and $B \to K^* μ^+ μ^-$. For the radiative decays, we find that the AdS/QCD DAs offer the advantage of avoiding end-point singularities when computing power suppressed contributions. For the semileptonic decays $B \to ρl ν$ and $B \to K^* μ^+ μ^-$, we compare our predictions to the latest BaBar and LHCb data respectively.

description: The objectives were to i) assess the effect of enhanced-efficiency nitrogen (N) fertilizers (EENF) [maleic itaconic acid copolymer (NSN) or 3,4-dimethylpyrazole phosphate (DMPP)] and urea on potato (Solanum tuberosum L.) tuber yield, N agronomic efficiency (NAE), N recovery efficiency in tuber (NREtuber) and plant (NREplant), N physiological efficiency, residual inorganic N in soil at harvest (Nresidual) and N losses (Nlosses) and ii) determine the impact of the amount of drainage water on NAE and Nlosses. On-farm experiments were conducted in seven sites with two fertilizers (EENF and urea) and two N rates (0 and 100 kg N ha−1). A N mass balance was used to calculate Nlosses. At two sites (one with NSN and one with DMPP), tuber yield response to N was greater with EENF than urea (avg. 5.0 Mg ha−1). NAE, NREtuber and NREplant were 17%, 31% and 25% higher with EENF than urea, respectively. These efficiencies decreased as drainage water increased. The estimated Nlosses were 12% lower with EENF, being the reduction particularly relevant with increasing drainage water. Therefore, using EENF in combination with irrigation management that ensures low drainage water amounts is essential for maximizing the fertilizer use efficiency and minimizing Nlosses in potato production systems.

description: This study focuses on heavy metals distribution and their ecological risk in river water, bed sediment, and suspended particulate matter (SPM) along the Ganga River basin. Overall abundance of the metals followed the sequence, Fe > Al > Mn > Pb > Ni > Cd > Cr > Zn > Co in water, Al > Fe > Mn > Zn > Cr > Cu > Ni > Co > Pb > Cd in bed sediment, while Al > Fe > Mn > Cr > Zn > Ni > Cu > Pb > Co > Cd in SPM. Among the abundant metals, Fe and Mn average concentrations exceeded BIS and WHO limits in river water. Similarly, Fe, Cd, and Zn, and most metals exceeded local background concentrations in bed sediment and SPM, respectively. Major ion chemistry in water signified carbonate weathering dominance during the time of sampling. Generally, Mn, Ni, Cu, Cr, and Co were derived from natural weathering and erosion, while Zn, Cd, and Pb were derived from both natural and anthropogenic sources. Metal index (MI) for river water showed that 27% of the locations were anthropogenically affected, whereas contamination factor and ecological risk assessment indicated highest contamination and risk from Cr and Cd in suspended sediments around urban centers in the middle basin. Furthermore, the confluence of Chambal and Yamuna increased heavy metal load in Yamuna and Ganga, respectively. The study highlighted the role of the water–sediment interaction indicating SPM is acting as a sink for metals followed by bed sediment.

description: Understanding the role that quantum entanglement plays as a resource in various information processing tasks is one of the crucial goals of quantum information theory. Here we propose a new perspective for studying quantum entanglement: distributed computation of functions without communication between nodes. To formalize this approach, we propose identity games. Surprisingly, despite of no-signaling, we obtain that non-local quantum strategies beat classical ones in terms of winning probability for identity games originating from certain bipartite and multipartite functions. Moreover we show that, for majority of functions, access to general non-signaling resources boosts success probability two times in comparison to classical ones, for number of outputs large enough.

description: We studied the effect of 17 beta-estradiol (E) on the proliferation and alkaline phosphatase activity of cultured UMR106 cells, a clonal osteoblastic cell line. Growth rates were reduced and alkaline phosphatase activity was increased in cells incubated for 2 days in medium containing E (10(-8) M). In contrast, E had no effect on the growth rates or alkaline phosphatase of a human fibroblastic cell line, S90E. The effect of E was not observed with low cell density or at confluence. 1,25-Dihydroxyvitamin D3 antagonized the response to E. Preincubation of the cells with dexamethasone, a potent inducer of differentiation, reversed the effect of E or 1,25-dihydroxyvitamin D3. These results indicate that cellular and/or extracellular factors such as cell density, the phase of the cell cycle, the state of differentiation, and the presence or absence of other steroids influenced the response of UMR106 cells to E. Serum was removed from the culture medium to minimize the effect of the steroids, growth factors, and nutrients present in serum. A striking stimulation of alkaline phosphatase by E occurred with serum-free conditions. This stimulation was biphasic over an E concentration from 10(-12) to 10(-8) M, with the peak response at 10(-10) M. The action of E on UMR106 cells was metabolite-specific, since the isomer 17 alpha-estradiol produced no effect on proliferation rates or alkaline phosphatase activity. The cyclic AMP response to parathyroid hormone (residues 1-34) was not altered by E treatment of these cells. In contrast, dexamethasone exposure did increase the cyclic AMP response to parathyroid hormone. These results demonstrate a direct effect of E on an osteoblastic cell line. They also raise the possibility that similar or identical actions of E occur in cultured normal osteoblasts.
An investigation into the effects of resonant acoustic mixing on energetic materials
Creators: name: Homan, Jordan
Publisher: name: Imperial College London

description: Energetic materials are highly complicated composite materials, designed to produce tailored outputs. A large part of their behaviour depends on the sample being a homogeneous material. As such, the processing of energetic materials is critical to optimise performance. Traditional methods are based around intrusive blade mixers, which take time, and due to safety considerations, do not necessarily produce a consistent material. Resonant acoustic mixing (RAM) is a novel non-intrusive technique which propagates acoustic vibrations into a sealed sample vessel. It is more efficient in both time and material, and opens up avenues for mixing novel materials. This programme is a comparative study designed to determine if RAM impacts energetic materials in comparison to a planetary mixed baseline. Starting with two-phase inert composites the composition was scaled up to a mimic PBX and then to a live PBX. A variation of characterisation was conducted; mechanical testing was conducted via dynamic mechanical analysis, hardness testing and split Hopkinson pressure bar. Thermal characterisation was conducted by thermo mechanical analysis and differential scanning calorimetry/thermogravimetric analysis. Chemical analysis was conducted by nuclear magenetic resonance and density testing was conducted by pycnometry. In addition, hazard testing and functionality testing was conducted on the explosive samples. The research found that mixing via RAM did not impact the material; however, it also highlighted a potential limitation. Several of the RAM compositions demonstrated significantly weaker mechanical properties due to poor curing of the binder caused by inconsistent distribution of the isocyanate through the material.

description: We present a symmetry analysis of electronic bandstructure including spin-orbit interaction close to the insulating gap edge in monolayer black phosphorus ('phosphorene'). Expressions for energy dispersion relation and spin-dependent eigenstates for electrons and holes are found via simplification of a perturbative expansion in wavevector $k$ away from the zone center using elementary group theory. Importantly, we expose the underlying symmetries giving rise to substantial anisotropy in optical absorption, charge and spin transport properties, and reveal the mechanism responsible for valence band distortion and possible lack of a true direct gap.

description: Mexico is the center of origin of maize and one of the phenomena that imperil maize conservation is transgene presence. Although previous studies have documented transgene presence in Mexican landraces, to date there is no countrywide transgene monitoring protocol, nor systematic analyses assessing which factors could be related with transgene presence and dispersal. In this work, we propose a geographically representative sampling protocol and present empirical data from three sampled states: Mexico City, Oaxaca and Chiapas. To further investigate which environmental and social variables could be associated with transgene presence, we carried out a data mining approach. To assess transgene presence in collected maize samples, we used Real-Time PCR, finding that transgenes were widely distributed across sampled localities: 33% of the localities in Chiapas, 25% in Mexico City and 11% in Oaxaca. The data mining approach allowed us to identify state-specific spatial associations in Chiapas and Oaxaca. In Chiapas, a higher probability of transgene presence appeared related to the coexistence of industrialized maize agriculture, while in Oaxaca it was related with seed exchange. We discuss the importance of implementing a national biomonitoring protocol to increase our understanding of the sources that enable transgene presence and dispersal.
An insulin-like growth factor (IGF) binding protein enhances the biologic response to IGF-I.

description: The insulin-like growth factors IGF-I and IGF-II circulate in blood bound to carrier proteins. The higher molecular mass IGF-binding protein complex (150 kDa) is composed of subunits, and one subunit that forms this complex is growth hormone dependent. In addition, many cell types and tissues secrete another form of IGF binding protein that is not growth hormone dependent. Both forms of the IGF binding protein are believed to inactivate the IGFs and to function as delivery systems to tissues. This conclusion was based on studies that determined the effects of impure preparations of these binding proteins or that examined the effect of these proteins only on the insulin-like actions of the IGFs. We report here that a pure preparation of the extracellular form of the IGF binding protein (purified from human amniotic fluid) markedly potentiated replication of several cell types in response to human IGF-I. Secondary cultures of human, mouse, and chicken embryo fibroblasts as well as porcine aortic smooth muscle cells showed marked enhancement of their DNA synthesis response (2.8- to 4.4-fold increases) to IGF-I in the presence of this protein. These responses were synergistic since the sum of the responses to either IGF-I or to the binding protein alone was between 8 and 17% of the increase obtained in cultures exposed to both peptides. The binding protein not only potentiated the DNA synthesis response but also enhanced the increase in cell number in response to IGF-I. This stimulation is specific for growth factors that bind to the binding protein since incubation with insulin, which binds to the type I IGF receptor but not to the binding protein, did not result in potentiation of this response. We conclude that a form of IGF binding protein that is present in extracellular fluids and is secreted by many types of cells can markedly potentiate the cellular response to IGF-I.

description: To exert their effects, glucocorticoid receptor complexes interact selectively with DNA sequences known as glucocorticoid regulatory elements. We have studied the interaction between human glucocorticoid receptors and mouse mammary tumor virus (MMTV) DNA by means of a procedure that permits analysis after immobilization of the receptor on nitrocellulose. Proteins from crude cytosolic or nuclear extracts were electrophoresed on NaDodSO4/PAGE gels, soaked in a urea buffer to remove NaDodSO4, transferred to nitrocellulose, and probed with nick-translated MMTV [32P]DNA in a 5% nonfat dry milk buffer, which minimizes nonselective DNA-protein interactions. We present evidence that MMTV [32P]DNA interacts selectively with the glucocorticoid receptor. These data include comigration of [3H]dexamethasone mesylate-labeled band and bound MMTV [32P]DNA on gel electrophoresis systems; localization of DNA-binding activity in the cytosol of cells incubated with steroid at 0 degrees C and in the nucleus and cytosol of cells incubated at 37 degrees C; binding of the MMTV DNA to highly purified receptor; and absence of MMTV DNA binding activity in extracts from cells whose receptor has been down-regulated. Furthermore, glucocorticoid receptors analyzed under these conditions exhibit selective binding to DNA fragments that contain glucocorticoid regulatory elements.

description: A discontinuous representation of the forelimb body surface in area 3b is proposed. Two different methods were used: single-neuron receptive-field (RF) mapping in unanesthetized cats (maximal RF) and multiunit RF mapping in deeply anesthetized cats (minimal RF). Ten or more maximal RFs were sampled in each of 14 near-radial microelectrode penetrations. In 6 penetrations, the maximal RFs of all sampled neurons (despite prominent variations in RF size and shape) shared in common a small skin area--termed the "RF center." Each of the remaining penetrations had to be divided into at least two segments (6 penetrations) or three segments (2 penetrations), for all maximal RFs mapped in a segment to include a common skin site. In six penetrations, after maximal RFs were mapped, deep general anesthesia was induced and minimal RFs were mapped in the same penetration at cortical sites separated by 150 microns. Minimal RFs closely matched the RF centers defined by maximal RFs in the same penetration. In penetrations that mapped two or three RF centers, a rapid transition in minimal RF position was detected at the same cortical site where the shift in RF center was detected. Closely spaced penetrations revealed discrete cortical columns, having the size and shape of 350- to 400-microns-diameter irregular hexagons, such that the identical minimal RF was mapped at any site within a column. The forelimb body surface in cat 3b thus appears to be represented by a mosaic of discrete columns--an organization similar to the whisker representation in rodent primary somatosensory cortex.

In der alltäglichen Tätigkeit als Fachkraft in der Heimerziehung zeigt sich sehr prägnant die Bedeutung von konstanter Bindungsqualität der Kinder und Jugendlichen zu ihren Bezugspersonen. Diese notwendige Bindungskontinuität steht jedoch einer hohen Fluktuation der Fachkräfte und Fachkräftemangel gegenüber. In dem Forschungsfeld der Heimerziehung gibt es jedoch bisher nur wenige empirische Studien, welche die Gründe für den Ausstieg und den Verbleib in der Heimerziehung untersuchen. Im Rahmen des Masterstudienganges „Innovationsmanagement in der Sozialen Arbeit“ mit dem Innovationsschwerpunkt „Kinder-, Jugend- und Familienhilfe“ der Katholischen Hochschule NRW (Abteilung Köln) soll das oben skizzierte „Fluktuations-Problem“ analysiert werden. Alle beteiligten Studierenden haben den Schwerpunkt der Kinder-, Jugend- und Familienhilfe in Rahmen des Masterstudiengangs gewählt, sind ebenfalls als Sozialarbeiter:innen und Sozialpädagog:innen tätig und weisen somit sowohl berufliche Erfahrungen in der Praxis als auch eine theoretische und fachliche Expertise auf.

description: Almost all homosexual patients with acquired immunodeficiency syndrome are also actively infected with human cytomegalovirus (HCMV). We have hypothesized that an interaction between HCMV and human immunodeficiency virus (HIV), the agent that causes acquired immunodeficiency syndrome, may exist at a molecular level and contribute to the manifestations of HIV infection. In this report, we demonstrate that the immediate-early gene region of HCMV, in particular immediate-early region 2, trans-activates the expression of the bacterial gene chloramphenicol acetyltransferase that is fused to the HIV long terminal repeat and carried by plasmid pHIV-CAT. The HCMV immediate-early trans-activator increases the level of mRNA from the plasmid pHIV-CAT. The sequences of HIV that are responsive to trans-activation by the HCMV immediate-early region are distinct from HIV sequences that required for response to the HIV tat. The stimulation of HIV gene expression by HCMV gene functions could enhance the consequences of HIV infection in persons with previous or concurrent HCMV infection.

description: The functions of epithelia that line small airways in mammalian lungs are unknown. To gain insight into the role of small-airway epithelia in lung liquid balance, Clara cells were isolated from excised rabbit lungs by enzymatic digestion, enriched by centrifugal elutriation and density centrifugation, and further purified by differential adherence to collagen matrices. The resulting cell population was composed of 85% Clara cells, 3% ciliated cells, and less than 1% macrophages. The remainder of the cells were not definitively identified. The transepithelial potential difference peaked on day 3 in culture. Preparations studied in Ussing flux chambers exhibited a potential difference of 8 mV (apical bath negative), a resistance of 500 ohm X cm2, and an equivalent short-circuit current (ISCeq) of 16 microA/cm2. Inhibition of the Na+/K+-ATPase by ouabain abolished ISCeq. Exposure of the apical surface to amiloride or replacement of Na+ in the apical bathing solution with an impermeant cation (N-methyl-D-glucamine) decreased ISCeq by 66% and 93%, respectively. Neither amiloride in the basolateral bathing solution, nor bumetanide, nor isoproterenol significantly altered basal ISCeq. These findings indicate that Clara cells in culture form polarized monolayers, Clara cells transport Na+ from the apical to the basolateral bathing solution, and the small airways of the rabbit may function in liquid absorption.

description: Semantic enhancement of existing metadata schemas for data documentation and exchange is presented, to cover the fundamental concepts needed within the DOME4.0 project. Concepts from the DCAT RDF vocabulary (and from the RDF schema which DCAT depends on) for the description of datasets and data services (and catalogues) have been mapped in an enriched semantic framework provided by the Elementary Multiperspective Material Ontology (EMMO). This is done by imposing constraints that enable
 the usage of the original DCAT concepts into an OWL 2 DL framework.
 A mapping ontology from DCAT together with an ontology extension of the EMMO in order to deal with specific data concepts is provided in a public repository. Results of this mapping will be ported into the OntoCommons Top Reference Ontology. This will make it usable also by other ontological approaches (e.g. BFO, DOLCE). This work offers innovative value via (i) providing the means to bridge between the state of the art widely used top level ontologies and widely used web standard metadata schemas/vocabularies;
 and (ii) presenting a novel means of ontologising such metadata schemas and bringing them to a high-level semantic logic.
 A first example of combination of syntactic description of data and semantic mapping, is also provided.

description: Lentropin, a factor present in the vitreous humor of the eye, stimulates lens fiber differentiation from chicken embryo lens epithelial cells in vitro. Lentropin has been partially purified but has not been isolated in sufficient quantity or purity for direct comparison with other growth and differentiation factors. Previous studies have shown that insulin and fetal bovine serum share with lentropin the ability to stimulate lens fiber formation from cultured epithelial cells. In the present study, a number of hormones and growth factors were assayed for lentropin activity. Of those tested, the only substances that had this activity were the insulin-like growth factors (IGFs) somatomedin C (Sm-C/IGF-I) and multiplication-stimulating activity (MSA/IGF-II). Sm-C/IGF-I was approximately 30 times more potent than insulin or MSA/IGF-II in promoting fiber cell formation. A monoclonal antibody to human Sm-C/IGF-I inhibited purified Sm-C/IGF-I, fetal bovine serum, and chicken vitreous humor from stimulating fiber cell differentiation in vitro. This antibody has been shown not to crossreact with insulin and did not block insulin-stimulated lens fiber formation. These findings indicate that lentropin is related to the IGFs and that these factors may play important roles in controlling cell differentiation, in addition to their better-known ability to stimulate cell division.

description: Introduction: The demand to increase reliability and reduce maintenance costs drives the search for new condition monitoring solutions of machines. Bearings are of special interest in this matter as they are main contributors to machine downtime. Therefore, this article investigates the electric behavior of a hydrodynamic journal bearing using impedance measurement.

Methods: For that purpose measurements are taken in boundary lubrication, mixed lubrication and hydrodynamic lubrication of a hydrodynamic journal bearing. In order to interpret the behaviour observed in these measurements, a phenomenological model is developed using the quantitative working space model. The measurement results are also interpreted using analogies to the Stribeck curve as a known tribological model. Additionally, measurements in mixed lubrication are analysed in detail.

Results: These measurements show that the electric behaviour of journal bearings changes significantly within the mixed lubrication regime. This change in behaviour shows three distinct states within mixed lubrication which helps to identify destructive operating conditions. Furthermore, the measurements potentially allow the detection of deformation or damage of the bearing in mixed lubrication.

Discussion: The quantitative analysis of the electric behaviour of journal bearings is possible in the mixed lubrication regime and can be used in future to extract condition and operating information from a system during operation.

description: Biosurfactants can be potentially used in food, cosmetics, pharmaceuticals, and environmental remediation because of their biodegradability and low toxicity. However, it is very challenging to recover biosurfactants from fermented broth as they are temperature-sensitive and present at dilute concentrations. This study aims to develop an alternative process that uses cloud point extraction (CPE) to recover lipopeptides biosurfactant from cell-free broth of Bacillus sp. GY19. The nonionic surfactant, Triton X-100, was selected as the aqueous-based solvent for CPE. Under the optimal conditions lipopeptides concentration in Triton X-100 was 23,000 mg/L, which is 14.8-folds higher than that in cell-free broth. Lipopeptides and Triton X-100 exerted a positive synergistic effect in reducing the critical micelle concentration of mixed micelles with a β value of −1.9. This could be considered a co-benefit of using CPE for biosurfactant recovery. Two techniques for back extraction of lipopeptides after the CPE process were proposed. Silica gel 60 selectively adsorbed Triton X-100 with 44% removal, while maintaining lipopeptides recovery at 86%. Cold acetone precipitation could remove 99% of Triton X-100 by precipitating lipopeptides. However, a 1%(w/v) SDS solution had to be used to re-solubilize the dehydrated lipopeptide
title: A Case Study in Software Reuse: The RNTDS Architecture

description: It has been asserted that the most significant gains in software productivity will come from increased levels of software reuse. Some economic models for predicting savings through software reuse exist, but none are based on actual project experience. This paper surveys those models and presents the results of a case study, the Restructured Naval Tactical Data Systems (RNTDS) architecture, in the light of those models. According to the models, software reuse via the RNTDS architecture has enabled the production of fourteen major computer programs at five to twenty-one percent of the cost to create them without software reuse. Organizational characteristics cited by the Software Engineering Institute as promoting reuse hold true for the RNTDS architecture. The high degree of software reuse in the architecture (89 to 99 percent reuse across fourteen programs) was made possible by a high degree of common functionality and from the use of design techniques which exploited it. A reusable component is not more expensive to produce a "non-reusable" one. Increased architectural and repository costs were equally offset by decreased component testing requirements. Also included in this paper are a brief survey of the software reuse state of the art and annotated and general software reuse bibliographies.

description: Protein I (P.I) is the major outer membrane protein of Neisseria gonorrhoeae and serves as a porin. By using oligonucleotide probes derived from the known amino-terminal sequence of the mature protein, we have cloned the gene encoding the P.I of gonococcal strain FA19 in three overlapping fragments and determined the DNA sequence. The gene sequence predicts a protein with characteristics typical of the porins of other Gram-negative bacteria. A clone expressing P.I in Escherichia coli was obtained by removing a portion of the P.I gene promoter and reconstructing the entire P.I gene in a position just downstream from a phage T7 promoter. Expression of P.I was then achieved by introducing this recombinant plasmid into an E. coli strain containing an inducible T7 polymerase gene. The clone produced a protein that was identical in size to native P.I and reacted with anti-P.I monoclonal antibodies. Prolonged expression of the protein apparently was lethal for E. coli, possibly explaining failures to clone an intact P.I gene with its own promoter.

description: In skeletal muscle, dihydropyridine receptors and dihydropyridine-sensitive Ca2+ channels are preferentially localized in the transverse tubular membranes. Starting with an antigenic membrane fraction enriched in rabbit muscle transverse tubules (T-tubules), several monoclonal antibodies were produced by a fusion of spleen cells from an immunized BALB/c mouse with P3 X 63Ag.8.6.5.3 mouse myeloma cells. Antibodies were screened according to a scheme designed to select IgG immunoglobins that recognized a determinant specifically associated with the T-tubule membrane. Antibodies that fulfilled the screening criteria were used in in vitro planar bilayer recording of the activity of the dihydropyridine-sensitive Ca2+ channel present in T-tubules. Cells producing one antibody (Ab 21) survived cloning dilution and stably produced a monoclonal antibody (mAb21-4) that increased the rate of single channel opening when interacting with the internal side of the channel protein. mAb21-4 immobilized by covalent crosslinking on beads (Affi-Gel 10) consistently immunoprecipitated polypeptide bands with the following electrophoretic mobility: Mr values of greater than or equal to 175,000; 90,000; 55,000; and 34,000.

description: We have examined the effect on respiration of the steroid hormone progesterone, administered either intravenously or directly into the medulla oblongata in anesthetized and paralyzed male and female cats. The carotid sinus and vagus nerves were cut, and end-tidal PCO2 and temperature were kept constant with servo-controllers. Phrenic nerve activity was used to quantitate central respiratory activity. Repeated doses of progesterone (from 0.1 to 2.0 micrograms/kg, cumulative) caused a sustained (greater than 45 min) facilitation of phrenic nerve activity in female and male cats; however, the response was much more variable in females. Progesterone injected into the region of nucleus tractus solitarii, a respiratory-related area in the medulla oblongata, also caused a prolonged stimulation of respiration. Progesterone administration at high concentration by both routes also caused a substantial hypotension. Identical i.v. doses of other classes of steroid hormones (17 beta-estradiol, testosterone, and cortisol) did not elicit the same respiratory effect. Pretreatment with RU 486, a progesterone-receptor antagonist, blocked the facilitatory effect of progesterone. We conclude that progesterone acts centrally through a steroid receptor-mediated mechanism to facilitate respiration.

description: Many practitioners and researchers in this field consider money to bethe centrepiece of complementary currencies. This paper identifies asecond line of thinking, through which the discourse on an‘alternative economy’ had a significant influence on the developmentof these social innovations during the 1980s and 1990s. This articlediscusses two questions: The first one concerns the influence of, andthe relationship between these two lines of thought. A monetary focusgradually superseded earlier interpretations of these systems andeventually occupied a dominant position. Is there sufficient commonground between researchers of cryptocurrencies and traditionalcomplementary currencies to share a single discourse network? Thesecond question concerns the potential of local currencies withstrictly limited convertibility. Against the background of animpending recession this article offers a perspective of how newlydesigned complementary currencies can become viable elements of analternative economic structure beside the capitalism economy.

description: We report on a systematic study of the structural, magnetic and transport properties of high-purity 1T-VS$_2$ powder samples prepared under high pressure. The results differ notably from those previously obtained by de-intercalating Li from LiVS$_2$. First, no Charge Density Wave (CDW) is found by transmission electron microscopy down to 94 K. Though, \textit{ab initio} phonon calculations unveil a latent CDW instability driven by an acoustic phonon softening at the wave vector ${\bf q}_{CDW} \approx$ (0.21,0.21,0) previously reported in de-intercalated samples. A further indication of latent lattice instability is given by an anomalous expansion of the V-S bond distance at low temperature. Second, infrared optical absorption and electrical resistivity measurements give evidence of non metallic properties, consistent with the observation of no CDW phase. On the other hand, magnetic susceptibility and NMR data suggest the coexistence of localized moments with metallic carriers, in agreement with \textit{ab initio} band structure calculations. This discrepancy is reconciled by a picture of electron localization induced by disorder or electronic correlations leading to a phase separation of metallic and non-metallic domains in the nm scale. We conclude that 1T-VS$_2$ is at the verge of a CDW transition and suggest that residual electronic doping in Li de-intercalated samples stabilizes a uniform CDW phase with metallic properties.

description: The Saccharomyces cerevisiae RAD3 gene, which is required for cell viability and excision repair of damaged DNA, encodes an 89-kDa protein that has a single-stranded DNA-dependent ATPase activity. We now show that the RAD3 protein also possesses a helicase activity that unwinds duplex regions in DNA substrates constructed by annealing DNA fragments of 71-851 nucleotides to circular, single-stranded M13 DNA. The DNA helicase activity is dependent on the hydrolysis of ATP, has a pH optimum of approximately 5.6, and is inhibited by antibodies raised against a truncated RAD3 protein produced in Escherichia coli. The RAD3 helicase translocates along single-stranded DNA in the 5'----3' direction. The direction of RAD3 helicase movement is consistent with the possibility that it unwinds DNA duplexes in advance of the replication fork during DNA replication.
