ESTand transcriptome analysis of cephalochordate amphioxusçpast , present and future

The cephalochordates, commonly known as amphioxus or lancelets, are now considered the most basal chordate group, and the studies of these organisms therefore offer important insights into various levels of evolutionary biology. In the past two decades, the investigation of amphioxus developmental biology has provided key knowledge for understanding the basic patterning mechanisms of chordates. Comparative genome studies of vertebrates and amphioxus have uncovered clear evidence supporting the hypothesis of two-round whole-genome duplication thought to have occurred early in vertebrate evolution and have shed light on the evolution of morphological novelties in the complex vertebrate body plan. Complementary to the amphioxus genome-sequencing project, a large collection of expressed sequence tags (ESTs) has been generated for amphioxus in recent years; this valuable collection represents a rich resource for gene discovery, expression profiling and molecular developmental studies in the amphioxus model. Here, we review previous EST analyses and available cDNA resources in amphioxus and discuss their value for use in evolutionary and developmental studies.We also discuss the potential advantages of applying high-throughput, next-generation sequencing (NGS) technologies to the field of amphioxus research.

Particle-number projected Bogoliubov-coupled-cluster theory: Application to the pairing Hamiltonian

Background: While coupled-cluster theory accurately models weakly correlated quantum systems, it often fails in the presence of strong correlations where the standard mean-field picture is qualitatively incorrect. In many cases, these failures can be largely ameliorated by permitting the mean-field reference to break physical symmetries. Symmetry-broken coupled-cluster, e.g., Bogoliubov-coupled-cluster, theory can indeed provide reasonably accurate energetic predictions, but the broken symmetry can compromise the quality of the resulting wave function and predictions of observables other than the energy. Purpose: Merging symmetry projection and coupled-cluster theory is therefore an appealing way to describe strongly correlated systems. One indeed expects to inherit and further improve the energetic accuracy of broken-symmetry coupled cluster while retaining proper symmetries. Methods: Independently, two different but related formalisms have been recently proposed to achieve this goal. The two formalisms are contrasted in this manuscript, with results tested on the Richardson pairing Hamiltonian. While the present paper focuses on the breaking and restoration of U(1) global-gauge symmetry associated with particle-number conservation, the symmetry-projected coupled-cluster formalism is applicable to other symmetries such as rotational (i.e., spin) symmetry. Results: Both formalisms are based on the disentangled cluster representation of the symmetry-rotated coupled-cluster wave function. However, they differ in the way that the disentangled clusters are solved. One approach sets up angle-dependent coupled-cluster equations, while the other involves first-order ordinary differential equations. The latter approach yields energies and occupation probabilities significantly better than those of number-projected Bardeen-Cooper-Schrieffer (BCS) and BCS coupled cluster and, when the disentangled clusters are truncated at low excitation levels, has a computational cost not too much larger than that of BCS coupled cluster. Conclusions: The high quality of results presented in this manuscript indicates that symmetry-projected coupled cluster is a promising method that can accurately describe both weakly and strongly correlated finite many-fermion systems.
Investigation of Localization Accuracy for UWB Radar Operating in Complex Environment

The aim of this paper is to investigate localization accuracy of ultra wideband (UWB) radar with a minimal antenna array taking in the account complexity of the real environment (extended and multiple targets, presence of wall or other obstacle in the line of sight, practical restrictions of antenna setting). Simulation-based results show how the localization accuracy depends on the radar range resolution, deployment of the radar antennas and the accuracy of ranges estimated between transmitting antenna-targetreceiving antenna. As the output, the distributions of the average localization errors in the monitored area are obtained. Their correctness is demonstrated by processing of the signals acquired by two M-sequence UWB radars with different range resolution and coverage.
Experimental Constraints on the Origin of the 1991 Pinatubo Dacite

Crystallisation and mantle-interaction experiments have been performed on the 1991 Pinatubo dacite to constrain its petrogenesis. In the dacite- H2O system at 1000 MPa, magnetite and either clinopyroxene or amphibole are the liquidus phases. No garnet is observed at this pressure. Dacite-mantle interaction at 920 MPa produces massive orthopyroxene crystallisation, in addition to amphibole ± phologopite. Amphibole crystallising in dacite at 1000 MPa faithfully reproduces aluminium-rich hornblende preserved in the cores of amphibole phenocrysts of the 1991 dacite, suggesting a high pressure stage of dacite crystallisation under high melt H2O contents (> 10 wt%) and low temperatures (< 950C). Altogether, plagioclase, amphibole and melt inclusion compositions suggest that the Pinatubo dacite was water-rich, oxidized and not much hotter than 900C, when emplaced in the shallow reservoir, in which most phenocrysts precipitated until the onset of the 1991 eruptions. The strongly fractionated REE pattern demands garnet somewhere during dacite genesis, which in turn requires high pressure derivation. Partial melting of subducted oceanic crust gives melts unlike the Pinatubo dacite. Interaction of these slab melts with sub-arc peridotite is unable to produce such type of dacite, nor is a direct mantle origin conceivable on the basis of mantle-dacite interaction experimental results. Dehydration melting of underplated basalts requires temperatures too high to match with petrological constraints and does not allow production of dacite melts having the low FeO/MgO, high H2O, Ni and Cr contents typical of Pinatubo-like magmas. On the face of chemical and phase equilibrium constraints, the most plausible origin of the Pinatubo dacite is via high pressure fractionation in the upper mantle of an hydrous, oxidised, primitive basalt that crystallises amphibole and garnet upon cooling, as shown by recent phase equilibrium work. Dacite melts so produced are directly expelled from the uppermost mantle or lower crust to shallow level storage reservoirs from which they erupt occasionally, following injection of H2O-poor mantle-derived basalts that can ascent without massive crystallisation unlike their hydrous counterparts, parental to dacite magmas, that rest at mantle depths. Dacites such as the Pinatubo one may thus witness particular H2O-rich conditions of the sub-arc mantle rather than the melting of a young and hot subducting oceanic plate.

Formation of silicon nanocrystals in sapphire by ion implantation and the origin of visible photoluminescence

Silicon nanocrystals, average sizes ranging between 3 and 7 nm, were formed in sapphire matrix by ion implantation and subsequent annealing. Evolution of the nanocrystals was detected by Raman spectroscopy and x-ray diffraction XRD. Raman spectra display that clusters in the matrix start to form nanocrystalline structures at annealing temperatures as low as 800 ° C in samples with high dose Si implantation. The onset temperature of crystallization increases with decreasing dose. Raman spectroscopy and XRD reveal gradual transformation of Si clusters into crystalline form. Visible photoluminescence band appears following implantation and its intensity increases with subsequent annealing process. While the center of the peak does not shift, the intensity of the peak decreases with increasing dose. The origin of the observed photoluminescence is discussed in terms of radiation induced defects in the sapphire matrix. © 2006 American Institute of Physics. DOI: 10.1063/1.2355543

The effect of estimation method and sample size in multilevel structural equation modeling

Multilevel structural equation modeling (multilevel SEM) has become an established method to analyze multilevel multivariate data. The first useful estimation method was the pseudobalanced method. This method is approximate because it assumes that all groups have the same size, and ignores unbalance when it exists. In addition, full information maximum likelihood (ML) estimation is now available, which is often combined with robust chi‐squares and standard errors to accommodate unmodeled heterogeneity (MLR). In addition, diagonally weighted least squares (DWLS) methods have become available as estimation methods. This article compares the pseudobalanced estimation method, ML(R), and two DWLS methods by simulating a multilevel factor model with unbalanced data. The simulations included different sample sizes at the individual and group levels and different intraclass correlation (ICC). The within‐group part of the model posed no problems. In the between part of the model, the different ICC sizes had no effect. There is a clear interaction effect between number of groups and estimation method. ML reaches unbiasedness fastest, then the two DWLS methods, then MLR, and then the pseudobalanced method (which needs more than 200 groups). We conclude that both ML(R) and DWLS are genuine improvements on the pseudobalanced approximation. With small sample sizes, the robust methods are not recommended.
THE EFFECTS OF SUBSIDIES ON PUBLIC TRANSIT LONG-RUN COSTS

This paper investigates sources of public transit long-run cost increases attributable to transit subsidies. The sources include wage, vehicle capital price and service increases. Service expansion is found to be the major source. Transit cost increases related to subsidies are classified as input price, output and finance effects of these subsidies. Transit costs are more responsive to federal operating subsidies, followed in declining order by local operating, state operating and capital subsidies, respectively.
Initiation of Mammalian Mitochondrial DNA Replication

Mitochondria produce most of the adenosine triphosphate required in a eukaryotic cell and they contain their own genome. The mitochondrial DNA (mtDNA) is a double stranded circular molecule that codes for proteins required for cellular respiration and RNA molecules involved in translation of these proteins. Replication of the mtDNA is therefore essential for cell viability and the aim of this thesis has been to understand the molecular mechanisms of mtDNA replication. In general, initiation of DNA replication involves a series of steps including recognition of an origin of replication, loading of replicative helicases, and synthesis of an RNA primer that can be used by DNA polymerases to initiate DNA synthesis. We have studied this process in mammalian mitochondria and demonstrate that the mitochondrial RNA polymerase (POLRMT) synthesizes the RNA primer required for initiation of lagging strand replication at the origin of light strand (OL). We have reconstituted, and in detail characterized, OL-dependent initiation of lagging strand replication in vitro using purified POLRMT and core factors of the mitochondrial replisome. We have also addressed how the TWINKLE helicase is loaded during initiation of leading strand replication. TWINKLE is a ring-shaped helicase and must be opened up to accommodate DNA in its central channel. Many helicases require specialized loading factor to assemble onto DNA, but we find that TWINKLE can function without such a factor. In the presence of the other components of the mitochondrial replisome, we show that TWINKLE can assemble on a DNA template resembling the mtDNA in vivo and support primer dependent initiation of DNA synthesis. Most mtDNA replication initiation events are prematurely terminated and do not result in duplication of the entire mtDNA molecule. We address the mechanisms responsible for this termination event and identify a highly conserved sequence with palindromic character located immediately downstream of the premature mtDNA replication termination site. Interestingly, transcription initiated at the heavy strand promoter (HSP) is also terminated at this region, suggesting that the termination sequence functions in a bidirectional manner. Based on the results of in vitro biochemistry and cell culture experiments, we propose that a trans-acting factor binds to the palindromic sequence and simultaneously directs termination of both mtDNA transcription and replication. MTERF1 binds specifically to an mtDNA sequence just downstream of the ribosomal RNA transcription unit. The function of MTERF1 has been debated and to elucidate its functional role in vivo, we here characterize an Mterf1 knock-out mouse model. We find that MTERF1 is non-essential and that the protein acts to prevent the transcription machinery from interfering with the downstream light strand promoter (LSP), an incidence that may disturb expression of coding genes, but also the formation of primers required for initiation of mtDNA replication.
Wechsler Adult Intelligence Scale, 3rd Edition (WAIS-III): Usefulness in the Early Detection of Alzheimer's Disease

We examined Alzheimer’s disease (AD) patients using a Japanese version of the Wechsler Adult Intelligence Scale, 3rd Edition (JWAIS-III) to clarify i) the significance of expansion of the indicated age range, ii) the characteristics of cognitive impairment in AD patients and iii) the efficacy of th neuropsychological assessment for the early detection of AD using the Digit Symbol subtest, which involves attention and episodic memory, and the Pairing supplementary test, which relates to digit symbol-incidental learning. The JWAIS-III was given to 43 AD patients (12 males and 31 females; mean age, 80.9 ± 6.3 years, who fulfilled the diagnostic cri teria for AD on the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSMIV) and the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer’s Disease and Related Disorders Association. Severity of dementia of the patients was classified according to Functional Assessment Staging (F) as follows: 9 patients in F3 (borderline), 15 in F4 (mild AD), 12 in F5 (moderate AD), 7 in F6 (somewhat severe AD) and none in F7 (severe AD). i) Mean intelligence quotients (IQs) were: Full Scale IQ 84.3 ± 14.0, Verbal IQ 84.6 ± 12.5 and Performance IQ 86.9 ± 15.5. Comparison of IQs and subtest scores of the patients aged 75 years or older assessed by standard scores for 70 to 74 years of age, which is the upper limit of the indicated age range on the WAIS-R (the previous version of the WAIS-III), with those assessed by the standard scores for the appropriate age revealed that the former were significantly lower in IQ and all subtest scores. ii) Significant differ ences were noted among the severities of dementia in the scores of 7 subtests for Similarities, Comprehension, Arithmetic, Digit Span, Letter-Number Sequencing, Digit Symbol and Symbol Search. iii) When both the Digit Symbol subtest scores of 7 points or more and the Digit Sumbol-Pairing supplementary test scores exceeding 10% of the cumulative percentile were regarded as normal, 11 of 15 (73.3%) patients in F4 (mild AD) could be detected. These find ings suggest that i) expansion of the indicated age range in the WAIS-III allows a more valid assessment of cognitive function in AD patients, ii) a marked decline in abstract thinking and verbal problem-solving ability and relative preservation of Perceptual organization are characteristics of cognitive impairment in AD patients and iii) a combination of the Digit Symbol subtest with the Pairing supplementary test is useful for the early detection of AD.
Photolithographic structuring of stretchable conductors and sub-kPa pressure sensors

This paper presents a novel method to prepare stretchable conductors and pressure sensors based on the gold/polydimethylsiloxane (PDMS) system. The gold films were sputtered onto structured PDMS surfaces produced with a photolithographic surface treatment with the aim of reducing tensile strains in the gold film. Scanning electron microscopy (SEM) and atomic force microscopy analyses showed that these 3D patterns reduce cracks and delaminations in the gold film. Electrical measurements indicate that the patterns also protect the films against repeated tensile cycling, although the un-patterned samples remained conducting as well after the completion of 120 cycles. The extrapolated resistivity value of the patterned sample (4.5 × 10−5 Ωcm) compares well with previously published data. SEM micrographs indicate that the pattern features deflect the cracks and therefore toughen the gold film. However, x-ray photoelectron spectroscopy and contact angle analyses indicate that the patterning process also slightly modifies the surface chemistry. This patterning method was used to prepare capacitive strain gauges with pressure sensitivity (ΔZ/Z)/P of 0.14 kPa−1 in the sub-kPa regime. Such stretchable and potentially conformal low-pressure sensors have not been produced before and could prove advantageous for many smart fabric applications.
Towards Identification of Areas of Reduced Risk in the Gulf of Finland, the Baltic Sea

A Lagrangian trajectory model, TRACMASS with the use of velocity fields calculated by the Rossby Centre (Swedish Hydrological and Meteorological Institute) circulation model, is employed to analyse trajectories of current-driven surface transport in the Gulf of Finland, the Baltic Sea, for the period of 1987-1991. Statistical analysis of trajectories is performed to calculate a map of probabilities for adverse impacts released in different sea areas to hit the coast. There is a clearly defined curve (equiprobability line) in the western part of the gulf from which the chances of the propagation of adverse impacts to either of the coasts are equal. The current-driven propagation of tracers from a wide area (of reduced risk) to the coast in the central and eastern parts of the gulf is unlikely within about three weeks. A safe fairway in terms of coastal protection goes over the equiprobability line and the area of reduced risk.
