RNA guided nucleotide modification of ribosomal and non-ribosomal RNAs in archaea
Creators: name: Ziesche, Sonia Madlen
Publisher: name: University of British Columbia
Year: 2009

description: Archaea use ribonucleoprotein (RNP) machines similar to those found in the eukaryotic nucleolus to methylate ribose residues in nascent ribosomal RNA. The archaeal complex required for this 2'-O-ribose-methylation consists of the C/D box sRNA guide and three proteins, the core RNA binding aL7a protein, the aNop56 protein and the methyltransferase fibrillarin protein. These RNP machines were reconstituted in vitro from purified recombinant components, and were shown to have methylation activity when provided with a simple target oligonucleotide, complementary to the sRNA guide sequence (Omer et al., 2002). The accuracy in directing methylation to the correct nucleotide in the target of the in vitro reconstituted C/D box RNP was shown. To obtain a better understanding of the versatility and specificity of this reaction, the activity of reconstituted particles on more complex target substrates (including 5S rRNA, tRNA[sup Gln] and "double guide" oligonucleotides that exhibit either direct or reverse complementarity to both the D' and D box guides) has been examined. The natural 5S rRNA and tRNA[sup Gln] substrates were efficiently methylated in vitro, providing that the complementarity between guide and target was approximately ten base pairs in length, and lacked mismatches. Maximal activity of double guide sRNAs required that both methylation sites be present in cis on the target RNA. These experiments defined the minimum number of components and conditions required to achieve in vitro, RNA guide directed 2'-O-ribose methylation of ribosomal and non-ribosomal target RNA.

description: We perform local numerical experiments to investigate the nonlinear stability of thin, radially-stratified disks. We demonstrate the presence of radial convective instability when the disk is nearly in uniform rotation, and show that the net angular momentum transport is slightly inwards, consistent with previous investigations of vertical convection. We then show that a convectively-unstable equilibrium is stabilized by differential rotation. Convective instability is determined by the Richardson number Ri = N_r^2/(qΩ)^2, where N_r is the radial Brunt-Vaisala frequency and qΩis the shear rate. Classical convective instability in a nonshearing medium (Ri -> -infinity) is suppressed when Ri > -1, i.e. when the shear rate becomes greater than the growth rate. Disks with a nearly-Keplerian rotation profile and radial gradients on the order of the disk radius have Ri > -0.01 and are therefore stable to local nonaxisymmetric disturbances. One implication of our results is that the ``baroclinic'' instability recently claimed by Klahr & Bodenheimer is either global or nonexistent. We estimate that our simulations would detect any genuine growth rate > 0.0025Ω.

description: According to the 1998-2008 Henan Statistic Yearbook, Grey Forecasting Model and Time Series Model are used to forecast the carrying capacity of cultivated land in Henan Province. According to the contradiction between limited carrying capacity of cultivated land and the growth of population and food safety, we should strictly implement land use planning, enhance the land protection awareness of farmers, establish effective mechanism of cultivated land protection, promote the land ecumenical and intensive use, actively carry out the land consolidation, strengthen law enforce, and improve the land use efficiency in order to protect the cultivated land. Result shows that natural population growth rate is gradually reduced in Henan Province and the increasing trend is gradually slowed down, but the population pressure is still relatively great due to the immense population base. Total population of Henan Province will break through 100million people in the year 2010. In the years 2010-2025, grain yield per unit area in Henan Province show a steady growth trend, with the average annual growth of 10.27%. Existing cultivated land resources in Henan Province can only meet the needs of daily life at the level of adequate food and clothing. With the growth of population, shortage of cultivated land resources is becoming more and more apparent, which will eventually hinder the economic development and the improvement of people’s living standard in Henan Province.

description: We study the periodic cubic derivative non-linear Schrödinger equation (dNLS) and the (focussing) quintic non-linear Schrödinger equation (NLS). These are both $L^2$ critical dispersive models, which exhibit threshold type behavior, when posed on the line ${\mathbb R}$. We describe the (three parameter) family of non-vanishing bell-shaped solutions for the periodic problem, in closed form. The main objective of the paper is to study their stability with respect to co-periodic perturbations. We analyze these waves for stability in the framework of the cubic DNLS. We provide a criteria for stability, depending on the sign of a scalar quantity. The proof relies on an instability index count, which in turn critically depends on a detailed spectral analysis of a self-adjoint matrix Hill operator. We exhibit a region in parameter space, which produces spectrally stable waves. We also provide an explicit description of the stability of all bell-shaped traveling waves for the quintic NLS, which turns out to be a two parameter subfamily of the one exhibited for DNLS. We give a complete description of their stability - as it turns out some are spectrally stable, while other are spectrally unstable, with respect to co-periodic perturbations.

description: We report the first demonstration of quantum key distribution over a standard telecom fiber exceeding 100 km in length. Through careful optimisation of the interferometer and single photon detector, we achieve a quantum bit error ratio of 8.9% for a 122km link, allowing a secure shared key to be formed after error correction and privacy amplification. Key formation rates of up to 1.9 kbit/sec are achieved depending upon fiber length. We discuss the factors limiting the maximum fiber length in quantum cryptography.

description: Precise time-dependent measurements of the Z = 2 component in the cosmic radiation provide crucial information about the propagation of charged particles through the heliosphere. The PAMELA experiment, with its long flight duration (15th June 2006 - 23rd January 2016) and the low energy threshold (80 MeV/n) is an ideal detector for cosmic ray solar modulation studies. In this paper, the helium nuclei spectra measured by the PAMELA instrument from July 2006 to December 2009 over a Carrington rotation time basis are presented. A state-of-the-art three-dimensional model for cosmic-ray propagation inside the heliosphere was used to interpret the time-dependent measured fluxes. Proton-to-helium flux ratio time profiles at various rigidities are also presented in order to study any features which could result from the different masses and local interstellar spectra shapes.
Systematically Asymmetric Heliospheric Magnetic Field: Evidence for a Quadrupole Mode and Non-axisymmetry with Polarity Flip-flops

description: Recent studies of the heliospheric magnetic field (HMF) have detected interesting, systematic hemispherical and longitudinal asymmetries which have a profound significance for the understanding of solar magnetic fields. The in situ HMF measurements since 1960s show that the heliospheric current sheet (HCS) is systematically shifted (coned) southward during solar minimum times, leading to the concept of a bashful ballerina. While temporary shifts can be considerably larger, the average HCS shift (coning) angle is a few degrees, less than the $7.2^{\circ}$ tilt of the solar rotation axis. Recent solar observations during the last two solar cycles verify these results and show that the magnetic areas in the northern solar hemisphere are larger and their intensity weaker than in the south during long intervals in the late declining to minimum phase. The multipole expansion reveals a strong quadrupole term which is oppositely directed to the dipole term. These results imply that the Sun has a symmetric quadrupole S0 dynamo mode that oscillates in phase with the dominant dipole A0 mode. Moreover, the heliospheric magnetic field has a strong tendency to produce solar tilts that are roughly opposite in longitudinal phase. This implies is a systematic longitudinal asymmetry and leads to a "flip-flop" type behaviour in the dominant HMF sector whose period is about 3.2 years. This agrees very well with the similar flip-flop period found recently in sunspots, as well as with the observed ratio of three between the activity cycle period and the flip-flop period of sun-like stars. Accordingly, these results require that the solar dynamo includes three modes, A0, S0 and a non-axisymmetric mode. Obviously, these results have a great impact on solar modelling.

description: Taking Dalu Town, Bishan County, Chongqing as an example, general characteristics of peasants’ awareness of land property rights, as well as its differences at different ages, education degree and income level are discussed, according to the questionnaire survey on peasants’ awareness of land property rights in 14 villages. Four suggestions are put forward to improve the property right system, such as adhering to the reform direction of collective ownership, defining the owner of the collective, giving the complete ownership power to the owner, and ensuring the usufructuary right of land for peasants. Result shows that the understanding of land ownership is obscure and the tendency of land privatization is insignificant. Nearly 2/3 peasants think that rural land belongs to the collective. And the right of land disposition is unclear. For instance, the village committee or village collective usually disposes the land belonging to the community, which is an act in excess of authority. There are differences in the recognition of property among different groups. Peasant households with different ages, education degrees and income levels have unclear understandings of land ownership and the tendency of land privatization is insignificant. There are also certain differences in the recognition of land disposition right among groups. Peasant households with different ages, education degrees and income levels have unclear understandings of land disposition right and land disposition in excess of authority usually happens.

description: Teaching programming to K-12 students has become essential. In this context, App Inventor is a popular block-based programming environment used by a wide audience, from K-12 to higher education, including end-users to create mobile applications to support their primary job or hobbies. Although learning programming with App Inventor has been investigated, a question that remains is which programming concepts are typically used and how this compares to other block-based programming environments. Therefore, we explore the characteristics of App Inventor projects through a large-scale analysis of 88,606 apps from the App Inventor Gallery. We discovered that the size of App Inventor projects varies from projects with very few blocks to some surprisingly large projects with more than 60,000 blocks. In general, much fewer design components are used than programming blocks, as typically, to work properly, several programming blocks are necessary for each design component in an App Inventor project. In addition, we also compare our results with the analysis of 233,491 Scratch projects reported by Aivaloglou and Hermans [4]. Several differences can be observed, as in App Inventor projects events are more predominant, with lesser use of conditionals and loops. These findings may guide the decision on the adoption of App Inventor for teaching computing depending on the specific learning objectives or indicate the need for tailoring the curricula.

description: Variation of cultivated land quality in 10 major cities and its driving forces are introduced in recent 10 years. And economic development and population growth are the common driving forces for the reduction of cultivated land in coastal cities. Among them, economic development is the main driving force. Taking Huludao City as an example, driving factors of cultivated land variation in Huludao City are studied by Principal Component Analysis according to the relevant statistical data in the year 1998-2007. Result shows that in recent 10 years, total cultivated land area has increased in Huludao City, especially in the years 1998-2002. Driving force of cultivated land variation in Huludao City can be summarized as economic growth, population growth and agricultural science and technology development. Based on this, relevant measures toproject cultivated land are put forward: controlling population, reducing land pressure; strengthening the protection of cultivated land and basic farmland, stabilizing cultivated land quality and quantity, strictly controlling the nonagricultural scale of cultivated land, improving the level of land economical and intensive use. Enhancing land consolidation, reclamation and development, increasing agricultural science and technology input, and guiding the adjustment of agricultural structure.

description: Germanium-based alloys hold great promise for future spintronics applications, due to their potential for integration with conventional Si-based electronics. Mn5Ge3 exhibits strong ferromagnetism up to the Curie temperature Tc~295K. We use Point Contact Andreev Reflection (PCAR) spectroscopy to measure the spin polarization of Mn5Ge3 epilayers grown by solid phase epitaxy on Ge(111). In addition, we calculate the spin polarization of bulk Mn5Ge3 in the diffusive and ballistic regimes using density-functional theory. The measured spin polarization, Pc=43+/-5% is compared to our theoretical estimates, PDFT=10+/-5% and 35+/-5% in the ballistic and diffusive limits respectively.

description: We discuss duality relations in correlated electronic ladder systems to clarify mutual relations between various conventional and unconventional phases. For the generalized two-leg Hubbard ladder, we find two exact duality relations, and also one asymptotic relation which holds in the low-energy regime. These duality relations show that unconventional (exotic) density-wave orders such as staggered flux or circulating spin-current are directly mapped to conventional density-wave orders, which establishes the appearance of various exotic states with time-reversal and/or spin symmetry breaking. We also study duality relations in the SO(5) symmetry that was proposed to unify antiferromagnetism and d-wave superconductivity. We show that the same SO(5) symmetry also unifies circulating spin current order and s-wave superconductivity.

description: Related literatures about ecological fragile is reviewed; the current status of ecological environment in the upper Min River basin is summarized. Equations for calculating the ecological footprint and ecological carrying capacity, as well as the standards of evaluating the status of ecological security are introduced. When ecological carrying capacity is greater than ecological footprint, ecosystem in this region is in safe state, and vice verse. According to the research data about five counties in upper Min River Basin, ecological footprint per capita and ecological capacity per capita are calculated in upper Min River Basin. Result shows that ecological system is in safe state in general. Interference of human activities on natural ecosystem has not exceeded the threshold of natural ecological carrying capacity; economic and social development is sustainable. However, ecological demand of fossil energy land, building land and farmland is greater than the supply. There are deficits in ecological footprint component. Among them, deficit of farmland is relatively large, which is in overloaded state. From the viewpoint of a state, ecological security in the upper Min River basin is not optimistic. However, from the global viewpoint, it is in sustainable condition. Utilization of resources is relatively extensive in the upper Min River basin with unreasonable consumption structure. In addition, economic development is achieved at the expense of natural resources.

description: Video summarization aims to select representative frames to retain high-level information, which is usually solved by predicting the segment-wise importance score via a softmax function. However, softmax function suffers in retaining high-rank representations for complex visual or sequential information, which is known as the Softmax Bottleneck problem. In this paper, we propose a novel framework named Dual Mixture Attention (DMASum) model with Meta Learning for video summarization that tackles the softmax bottleneck problem, where the Mixture of Attention layer (MoA) effectively increases the model capacity by employing twice self-query attention that can capture the second-order changes in addition to the initial query-key attention, and a novel Single Frame Meta Learning rule is then introduced to achieve more generalization to small datasets with limited training sources. Furthermore, the DMASum significantly exploits both visual and sequential attention that connects local key-frame and global attention in an accumulative way. We adopt the new evaluation protocol on two public datasets, SumMe, and TVSum. Both qualitative and quantitative experiments manifest significant improvements over the state-of-the-art methods.

description: The fact that electrical current is carried by individual charges has been known for over 100 years, yet this discreteness has not been directly observed so far. Almost all current measurements involve measuring the voltage drop across a resistor, using Ohm's law, in which the discrete nature of charge does not come into play. However, by sending a direct current through a microelectronic circuit with a chain of islands connected by small tunnel junctions, the individual electrons can be observed one by one. The quantum mechanical tunnelling of single charges in this one-dimensional array is time correlated, and consequently the detected signal has the average frequency f=I/e, where I is the current and e is the electron charge. Here we report a direct observation of these time-correlated single-electron tunnelling oscillations, and show electron counting in the range 5 fA-1 pA. This represents a fundamentally new way to measure extremely small currents, without offset or drift. Moreover, our current measurement, which is based on electron counting, is self-calibrated, as the measured frequency is related to the current only by a natural constant.

description: The program HiggsBounds is a well-established tool for testing Beyond-the-Standard Model (BSM) theories with an extended Higgs sector against experimental limits from collider searches at LEP, Tevatron and LHC. Thus far, it could be applied to any neutral or charged Higgs bosons originating from the modified Higgs sector. Implicitly, these particles were assumed to exhibit a somewhat hierarchical Yukawa structure as present in the Standard Model, where in particular the couplings to first generation fermions could be neglected. In this work, we extend the HiggsBounds functionalities to go beyond these restrictions, thus making the code applicable to any neutral or charged BSM scalars. Moreover, we develop a new approach to implement experimental searches whose kinematic acceptance depends significantly on the values of the involved couplings. We achieve this by recasting the searches to general scalar models. Using this approach we incorporate relevant current experimental limits from LHC searches for exotic scalars, and present the implications of these limits for a dark matter scalar mediator model, a flipped Two-Higgs-Doublet Model and a supersymmetric model with R-parity violation.

Ni 3d related electron states appear due to formation of Ni clusters. We show the possibility of changing the minority-spin DOS with Ni doping, while the majority-spin DOS remains almost unchanged. The total magnetic moment decreases with excess Ni. The total energy calculations corroborate the experimentally reported changes in the Curie temperature and the martensitic transition temperature with x.

Neural Representations of Procedural Knowledge

Subjects: Neuroscience

description: Although declarative concepts (e.g., apple) have been shown to be identifiable from their fMRI signatures, the correspondence has yet to be established for executing a complex procedure like tying a knot. Seven participants were trained to tie seven knots. Their neural representations of these seven procedures were assessed with fMRI as they imagined tying each knot. A subset of the trained participants physically tied each knot in a later fMRI session. We demonstrate that: (1) procedural knowledge of tying a particular knot is reliably identified from its fMRI signature; (2) procedural signatures were found in frontal, parietal, motor, and cerebellar regions; and (3) planning to tie knots was reliably identifiable prior to physical tying, using a classifier trained on mental tying signatures, indicating the similarity of the procedural signatures in the two cases. The findings indicate that fMRI activation patterns can illuminate the representation and organization of procedural knowledge.

This noun bias is a robust feature of early word learning for children acquiring English; however, it is not clear that it is a universal feature of word learning. Gillette, Gleitman, Gleitman, and Lederer (1999) have shown that adults exhibit an analogous noun bias in a simulated word learning (SVL) task in which they watch silent video clips of mothers interacting with their toddlers, and are asked to identify target nouns and verbs uttered by the mothers. In previous work, Western adults correctly identified more nouns than verbs in this task. In the current work, adults from three different cultural groups (Western, Eastern, and Second Generation) were tested in two versions of the SVL task, and only Westerners showed consistent evidence of a noun bias. In Experiment 1, participants were tested in a version of the SVL task in which the mother/toddler pairs were Western. Westerners showed a robust noun bias in this task, but Second Generation and Eastern participants did not. In Experiment 2, participants were tested in a version of the SVL task in which the mother/toddler pairs were Eastern. Western and Second Generation participants showed a noun bias, but Easterners did not. In Experiment 3, a narrower definition of "Eastern" (compared to Experiment 1) was adopted, and participants were again tested in the Western version of the SVL task. All three groups showed a noun bias; however, the bias was strongest for Westerners, weaker for Second Generation participants, and weakest for Easterners. When results from the Eastern and Western versions of the task were compared, there was a clear interaction between the cultural background of participants and the version on which they were tested. Overall, the findings indicate that nouns are more readily identifiable in a simulated vocabulary learning task, but only Westerners show a robust noun bias in this task.

description: Most polymers are long-lasting and produced from monomers derived from fossil fuel sources. Bio-based and/or biodegradable plastics have been proposed as a sustainable alternative. Amongst those available, polyhydroxyalkanoate (PHA) shows great potential across a large variety of applications but is currently limited to packaging, cosmetics and tissue engineering due to its relatively poor physical properties. An expansion of its uses can be accomplished by developing nanocomposites where PHAs are used as the polymer matrix. Herein, a PHA biopolyester was melt blended with graphene nanoplatelets (GNPs) or with a 1:1 hybrid mixture of GNPs and carbon nanofibers (CNFs). The resulting nanocomposites exhibited enhanced thermal stability while their Young's modulus roughly doubled compared to pure PHA. The hybrid nanocomposites percolated electrically at lower nanofiller loadings compared to the GNP-PHA system. The electrical conductivity at 15 wt.% loading was ~ 6 times higher than the GNP-based sample. As a result, the electromagnetic interference shielding performance of the hybrid material was around 50% better than the pure GNPs nanocomposites, exhibiting shielding effectiveness above 20 dB, which is the threshold for common commercial applications. The thermal conductivity increased significantly for both types of bio-nanocomposites and reached values around 5 W K-1 m-1 with the hybrid-based material displaying the best performance. Considering the solvent-free and industrially compatible production method, the proposed multifunctional materials are promising to expand the range of application of PHAs and increase the environmental sustainability of the plastic and plastic electronics industry.

description: Firstly, the paper introduces some researches on the development of tourism in Sichuan by researchers at home from a perspective of policies, pointing out that in these researches on tourism development in Sichuan, innovative breakthroughs are lacking. Secondly, by studying on total retail sales of social consumer goods of Sichuan and Hangzhou these 2 places, tourism incomes and the number of tourists at home, selecting the degree of tourism dependence, the contribution rate of tourism to economy and the growth rate of economy which tourism brought these 3 standards, and according to some related statistics of Sichuan from 2002 to 2009, the paper makes a detailed study on influences of tourism on economy by means of Grey Relational analysis in terms of small samples and inadequate information. And analyzing the rates of dependence, contribution and pull coefficient of tourism on economy by comparing Sichuan with Hangzhou these 2 places. The results show that influence of tourism on goods consumption of Hangzhou is much bigger than that of Sichuan. The degree of dependence of GDP in Hangzhou is bigger than that in Sichuan. Except in 2006 and 2007, the contribution rate of tourism on economy and the power of accelerating of tourism of Hangzhou is bigger than that of Sichuan. And finally, this paper proposes that the government should increase the investment in places of scenic beauty and improve the management of the scenery to accelerate the development of tourism of Sichuan.

description: The ability of the grid marketing system for fed cattle to provide an efficient price transmission mechanism is investigated. Nerlove’s (1958) adaptive expectations approach is adopted to model the relationship between grid premiums (discounts) and the weekly relative supply of carcass quality attributes. Linear regression techniques are used to estimate Nerlove’s supply response function. Granger Causality tests are conducted to investigate the relationship between grid premiums (discounts) and the relative supply of carcass quality attributes. Regression estimates and the Granger Causality tests provide empirical support for the 2005 National Beef Quality Audit call for clearer market signals.

description: DeepGreen is an automated delivery service for open access articles. Originally conceived to take advantage of the so-called open access component—a secondary publication right in Alliance and National licences in Germany to promote green open access—it aims to streamline open access processes by automating the distribution of full-text articles and metadata from publishers to repositories. The service, developed by a consortium and funded by the German Research Foundation (DFG) in its initial phase, has successfully established itself as a national service, facilitating open access content distribution and contributing to Germany's open access infrastructure. As of December 2024, DeepGreen distributes articles from 14 publishers to 84 institutional repositories and 6 subject-specific repositories. This article describes the role of the DeepGreen service in Germany, its collaboration with publishers and the potential of automated processes for storing articles in open access repositories, which, as publicly owned institutional infrastructures, ensure sustainable access and provide secure, redundant storage.

description: We present a motivated exposition of the proof of the following Tverberg Theorem: For every integers $d,r$ any $(d+1)(r-1)+1$ points in $\mathbb R^d$ can be decomposed into $r$ groups such that all the $r$ convex hulls of the groups have a common point. The proof is by well-known reduction to the Bárány Theorem. However, our exposition is easier to grasp because additional constructions (of an embedding $\mathbb R^d\subset\mathbb R^{d+1}$, of vectors $φ_{j,i}$ and statement of the Barańy Theorem) are not introduced in advance in a non-motivated way, but naturally appear in an attempt to construct the required decomposition. This attempt is based on rewriting several equalities between vectors as one equality between vectors of higher dimension.

A Comparison of the Chemical Evolutionary Histories of the Galactic Thin Disk and Thick Disk Stellar Populations
Creators: name: Brewer, Mary-Margaret

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: We have studied 23 long-lived G dwarfs that belong to the thin disk and thick disk stellar populations. Abundances have been derived for 24 elements: O, Na, Mg, Al, Si, Ca, Ti, Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Zr, Ba, La, Ce, Nd, and Eu. We find that the behavior of [alpha/Fe] and [Eu/Fe] vs. [Fe/H] are quite different for the two populations. As has long been known, the thin disk O, Mg, Si, Ca, and Ti ratios are enhanced relative to iron at the lowest metallicities, and decline toward solar values as [Fe/H] rises above -1.0. For the thick disk, the decline in [alpha/Fe] and [Eu/Fe] does not begin at [Fe/H] = -1.0, but at -0.4. Other elements share this behavior, including Sc, Co, and Zn, suggesting that at least in the chemical enrichment history of the thick disk, these elements were manufactured in similar-mass stars. Combining our results for the oldest and longest-lived stars with prior work, we find clear signs for an independent origin for the Galactic thick disk. (Abridged)

description: In a recent paper, we have presented a generative adversarial network (GAN)-based model for unconditional generation of the mel-spectrograms of singing voices. As the generator of the model is designed to take a variable-length sequence of noise vectors as input, it can generate mel-spectrograms of variable length. However, our previous listening test shows that the quality of the generated audio leaves room for improvement. The present paper extends and expands that previous work in the following aspects. First, we employ a hierarchical architecture in the generator to induce some structure in the temporal dimension. Second, we introduce a cycle regularization mechanism to the generator to avoid mode collapse. Third, we evaluate the performance of the new model not only for generating singing voices, but also for generating speech voices. Evaluation result shows that new model outperforms the prior one both objectively and subjectively. We also employ the model to unconditionally generate sequences of piano and violin music and find the result promising. Audio examples, as well as the code for implementing our model, will be publicly available online upon paper publication.
