description: Background: Chronic ankle instability, developing from ankle sprain, is one of the most common sports injuries. Besides it being an ankle issue, chronic ankle instability can also cause additional injuries. Investigating the epidemiology of chronic ankle instability is an essential step to develop an adequate injury prevention strategy. However, the epidemiology of chronic ankle instability remains unknown. Therefore, the purpose of this study was to investigate the epidemiology of chronic ankle instability through valid and reliable self-reported tools in active populations. Methods: An electronic search was performed on PubMed and Web of Science in July 2020. The inclusion criteria for articles were peer-reviewed, published between 2006 and 2020, using one of the valid and reliable tools to evaluate ankle instability, determining chronic ankle instability based on the criteria of the International Ankle Consortium, and including the outcome of epidemiology of chronic ankle instability. The risk of bias of the included studies was evaluated with an adapted tool for the sports injury review method. Results: After removing duplicated studies, 593 articles were screened for eligibility. Twenty full-texts were screened and finally nine studies were included, assessing 3804 participants in total. The participants were between 15 and 32 years old and represented soldiers, students, athletes and active individuals with a history of ankle sprain. The prevalence of chronic ankle instability was 25%, ranging between 7 and 53%. The prevalence of chronic ankle instability within participants with a history of ankle sprains was 46%, ranging between 9 and 76%. Five included studies identified chronic ankle instability based on the standard criteria, and four studies applied adapted exclusion criteria to conduct the study. Five out of nine included studies showed a low risk of bias. Conclusions: The prevalence of chronic ankle instability shows a wide range. This could be due to the different exclusion criteria, age, sports discipline, or other factors among the included studies. For future studies, standardized criteria to investigate the epidemiology of chronic ankle instability are required. The epidemiology of CAI should be prospective. Factors affecting the prevalence of chronic ankle instability should be investigated and clearly described.

Detecting a rotation in the epsilon Eridani debris disc

description: The evidence for a rotation of the epsilon Eridani debris disc is examined. Data at 850 micron wavelength were previously obtained using the Submillimetre Common User Bolometer Array (SCUBA) over periods in 1997-1998 and 2000-2002. By chi-square fitting after shift and rotation operations, images from these two epochs were compared to recover proper motion and orbital motion of the disc. The same procedures were then performed on simulated images to estimate the accuracy of the results. Minima in the chi-square plots indicate a motion of the disc of approximately 0.6'' per year in the direction of the star's proper motion. This underestimates the true value of 1'' per year, implying that some of the structure in the disc region is not associated with epsilon Eridani, originating instead from background galaxies. From the chi-square fitting for orbital motion, a counterclockwise rotation rate of ~2.75 degrees per year is deduced. Comparisons with simulated data in which the disc is not rotating show that noise and background galaxies result in approximately Gaussian fluctuations with a standard deviation +/-1.5 degrees per year. Thus counterclockwise rotation of disc features is supported at approximately a 2-sigma level, after a 4-year time difference. This rate is faster than the Keplerian rate of 0.65 degrees per year for features at ~65 AU from the star, suggesting their motion is tracking a planet inside the dust ring. Future observations with SCUBA-2 can rule out no rotation of the epsilon Eridani dust clumps with ~4-sigma confidence. Assuming a rate of about 2.75 degrees per year, the rotation of the features after a 10-year period could be shown to be >1 degree per year at the 3-sigma level.

description: Globular clusters (GCs) are dense, gravitationally bound systems of thousands to millions of stars. They are preferentially associated with the oldest components of galaxies, and measurements of their composition can therefore provide insight into the build-up of the chemical elements in galaxies in the early Universe. We report a massive GC in the Andromeda Galaxy (M31) that is extremely depleted in heavy elements. Its iron abundance is about 800 times lower than that of the Sun, and about three times lower than in the most iron-poor GCs previously known. It is also strongly depleted in magnesium. These measurements challenge the notion of a metallicity floor for GCs and theoretical expectations that massive GCs could not have formed at such low metallicities.

description: Accurate measurements of the mass distribution in galaxy and cluster halos are essential to test the cold dark matter (CDM) paradigm. The cosmological model predicts a universal shape for the density profile in all halos, independent of halo mass. Its profile has a `cuspy' centre, with no evidence for the constant density core. In this paper we carry out a careful analysis of twelve galaxy clusters, using Chandra data to compute the mass distribution in each system under the assumption of hydrostatic equilibrium. Due to their low concentration, clusters provide ideal objects for studying the central cusps in dark matter halos. The majority of the systems are consistent with the CDM model, but 4 objects exhibit flat inner density profiles. We suggest that the flat inner profile found for these clusters is due to an underestimation of the mass in the cluster centre (rather than any problem with the CDM model), since these objects also have a centrally peaked gas mass fraction. We discuss possible causes for erroneously low mass measurements in the cores of some systems.

The central importance of such a type formulas is beyond any doubt. Recent publications do confirm this historically established experience. Its links via umbrality to combinatorics are known at least since Rota and Mullin source papers then up to recently extended by many authors to be indicated in the sequel.

description: With the help of a real effort experiment, we analyze if tax evasion depends on the amount of effort invested to generate income. In three treatments, subjects were either endowed with income or had to work moderately or hard to earn it. In line with prospect theory, subjects evaded more taxes when they worked hard for their income. We find little evidence for the prediction that tax evasion in the endowed treatment is higher than in the moderate work treatment.
Optical spectroscopy of 4U 1812-12: an ultra-compact X-ray binary seen through an H II region

description: The persistent, low-luminosity neutron star X-ray binary 4U 1812-12 is a potential member of the scarce family of ultra-compact systems. We performed deep photometric and spectroscopic optical observations with the 10.4 m Gran Telescopio Canarias in order to investigate the chemical composition of the accreted plasma, which is a proxy for the donor star class. We detect a faint optical counterpart (g~25, r~23) that is located in the background of the outskirts of the Sharpless 54 H II region, whose characteristic nebular lines superimpose on the X-ray binary spectrum. Once this is corrected for, the actual source spectrum lacks hydrogen spectral features. In particular, the Halpha emission line is not detected, with an upper limit (3 sigma) on the equivalent width of <1.3 A. Helium (He I) lines are neither observed, albeit our constraints are not restrictive enough to properly test the presence of this element. We also provide stringent upper limits on the presence of emission lines from other elements, such as C and O, which are typically found in ultra-compact systems with C-O white dwarfs donors. The absence of hydrogen features, the persistent nature of the source at low luminosity, as well as the low optical to X-ray flux ratio confirm 4U 1812-12 as a compelling ultra-compact X-ray binary candidate, for which we tentatively propose a He-rich donor based on the optical spectrum and the detection of short thermonuclear X-ray bursts. In this framework, we discuss the possible orbital period of the system according to disc instability and evolutionary models.

What niche did human cooperativeness evolve in?

description: The Prisoner’s Dilemma (PD) is widely used to model social interaction between unrelated individuals in the study of the evolution of cooperative behaviour in humans and other species. Many effective mechanisms and promotive scenarios have been studied which allow for small founding groups of cooperative individuals to prevail even when all social interaction is characterised as a PD. Here, a brief critical discussion of the role of the PD as the most prominent tool in cooperation research is presented, followed by two new objections to such an exclusive focus on PD-based models of social interaction. It is highlighted that only 2 of the 726 combinatorially possible strategically unique ordinal 2x2 games have the detrimental characteristics of a PD and that the frequency of PD-type games in a space of games with random payoffs does not exceed about 3.5%. Although these purely mathematical considerations do not compellingly imply that the relevance of PDs is overestimated, it is proposed that, in the absence of convergent empirical information about the ancestral human social niche, this finding can be interpreted in favour of a so far rather neglected answer to the question of how the founding groups of human cooperation themselves came to cooperate: Behavioural and/or psychological mechanisms which evolved for other, possibly more frequent, social interaction situations might have been applied to PDtype dilemmas only later. Human cooperative behaviour might thus partly have begun as a cooptation.

An inclusive cross section of 41.4(12) mb was obtained for the reaction, compared to a theoretical prediction of 85.4 mb, hence only 48(2)% of the theoretical cross section is exhausted. This reduction in the observed spectroscopic strength is consistent with that found for lighter well-bound nuclei. One-neutron removal spectroscopic factors of 0.58(11) to the ground state and 3.7(2) to all excited states of $^{56}$Ni were deduced.

description: This paper provides a theoretic model for the analysis of cartel formation in an industry that is subject to profit shocks. The competitive or collusive conduct of a firm is determined by a decision maker who maximizes the present value of utility that accrues to him by earning a share of the firm's profit. The paper assumes that, first, factors like progressive taxation, shareholders' preference for smooth profits, or risk aversion may make the utility function of the decision maker rise concavely in the profits of the firm. Second, collusion causes the decision maker a dis-utility by violating legal and, thus, ethical or social norms. This disutility is independent from the level of profits. Concavity has adverse effects on collusion by making the decision maker value the additional utility from, first, establishing a new cartel, second, deviating from an existing cartel and, third, being punished for this deviation higher when the industry is in a bad state with low profits. Under these conditions, a negative profitability shock must be rather persistent to trigger cartel formation. Persistence prevents a newly formed cartel from falling apart quickly as the intense punishment in this state would also persist for a long time.
Microscopic shell-model counterpart of the Bohr-Mottelson model

description: In the present paper we demonstrate that there exists a fully microscopic shell-model counterpart of the Bohr-Mottelson model by embedding the latter in the microscopic shell-model theory of atomic nucleus within the framework of the recently proposed fully microscopic proton-neutron symplectic model (PNSM). For this purpose, another shell-model coupling scheme of the PNSM is considered in which the basis states are classified by the algebraic structure $SU(1,1) \otimes SO(6)$. It is shown that the configuration space of the PNSM contains a six-dimensional subspace that is closely related to the configuration space of the generalized quadrupole-monopole Bohr-Mottelson model and its dynamics splits into radial and orbital motions. The group $SO(6)$ acting in this space, in contrast, e.g., to popular IBM, contains an $SU(3)$ subgroup which allows to introduce microscopic shell-model counterparts of the exactly solvable limits of the Bohr-Mottelson model that closely parallel the relationship of the original Wilets-Jean and rotor models. The Wilets-Jean-type dynamics in the present approach, in contrast to the original collective model formulation, is governed by the microscopic shell-model intrinsic structure of the symplectic bandhead which defines the relevant Pauli allowed $SO(6)$, and hence $SU(3)$, subrepresentations. The original Wilets-Jean dynamics of the generalized Bohr-Mottelson model is recovered for the case of closed-shell nuclei, for which the symplectic bandhead structure is trivially reduced to the scalar or equivalent to it irreducible representation.

description: In evolutionary models of indirect reciprocity, reputation mechanisms can stabilize cooperation even in severe cooperation problems like the prisoner’s dilemma. Under certain circumstances, conditionally cooperative strategies (“cooperate iff your partner has a good reputation”) cannot be invaded by any other strategy that conditions behavior only on own and partner reputation. Still, the evolutionary version of backward induction can lead to a breakdown of this kind of indirect reciprocity. Backward induction, however, requires strategies that count and then cease to cooperate in the last, last but one, last but two, … game they play. These strategies are unlikely to exist in natural settings.
We present two new findings. (1) Surprisingly, the same kind of breakdown is also possible without counting. Opportunists using rare golden opportunities for defection can invade conditional cooperators. This can create further golden opportunities, inviting the next wave of opportunists, and so on, until cooperation breaks down completely. (2) Cooperation can be stabilized against these opportunists by letting an individual’s initial reputation be inherited from that individual’s parent. This ‘inclusive reputation’ mechanism can cope with any observably opportunistic strategy. Offspring of opportunists who successfully exploited a conditional cooperator cannot repeat their parents’ success because they inherit a bad reputation, which forewarns conditional cooperators in later generations.

description: Some say that, while the future is often chancy, the past cannot be. I disagree: I say that the past can be chancy, in some possible situations. Specifically, I say that past chanciness is possible in some cases of backwards causation; that is, in some cases whereby a later event causes an earlier one. In this dissertation, I defend the possibility of past chanciness, along with a view of chance that permits it. First, I set out a commonly endorsed and intuitively plausible view of chance, according to which chance is intimately related to time, and the past cannot be chancy. Then, using a particular case of backwards causation, I raise two problems for this view, and argue that it ought to be rejected. Finally, I propose and defend an alternative view, according to which chance is intimately related to causation, not time. According to this view, past chanciness is possible: it's not the past that can't be chancy, but rather the causal history. I argue that this causal view of chance delivers many of the benefits of its temporal cousin, while correctly handling cases of backwards causation, including our problem case. I defend the causal view against potential objections, and conclude that we ought to accept it.

description: In this paper, we explore the determinants of newswire coverage of Federal Reserve (Fed) communications. Our sample covers all 344 forward‐looking communications made in the period May 1999–May 2004. We find, first, that there is a higher likelihood of newswire coverage for monetary policy reports and speeches by Chairman Greenspan than for testimony and speeches by other Fed members. Furthermore, communications with an explicit monetary policy inclination or tone different from the current interest rate path are particularly likely to be covered. However, the release of important macroeconomic news reduces the likelihood of newswire coverage. Second, speeches by regional Fed presidents are relatively less likely to be reported than speeches by Board members. Nevertheless, newswire coverage of Fed president speeches is more likely if central bank communication is stale. Finally, our results indicate that Ben Bernanke played a distinguished role even before his chairmanship.

description: Mutual aid among villagers in developing countries is often the only means of insuring against economic shocks. We use “lab-in-the-field experiments” in Cambodian villages to study solidarity in established and newly resettled communities. Our experimental participants were part of an agricultural land-distribution project for which they signed up voluntarily. Half of our sample voluntarily resettled one and a half years before this study. Playing a version of the “solidarity game,” we identify the effect of voluntary resettlement on willingness to help anonymous fellow villagers. We find that resettled farmers transfer substantially less money to their fellow villagers than farmers who have not resettled. Our experimental results indicate greater vulnerability on the part of resettled households in the initial years after resettlement.

description: We present an experimental demonstration of Additive Point Source Localization (APSL), a sparse parametric imaging algorithm that reconstructs the 3D positions and activities of multiple gamma-ray point sources. Using a handheld gamma-ray detector array and up to four $8$ $μ$Ci $^{137}$Cs gamma-ray sources, we performed both source-search and source-separation experiments in an indoor laboratory environment. In the majority of the source-search measurements, APSL reconstructed the correct number of sources with position accuracies of ${\sim}20$ cm and activity accuracies (unsigned) of ${\sim}20\%$, given measurement times of two to three minutes and distances of closest approach (to any source) of ${\sim}20$ cm. In source-separation measurements where the detector could be moved freely about the environment, APSL was able to resolve two sources separated by $75$ cm or more given only ${\sim}60$ s of measurement time. In these source-separation measurements, APSL produced larger total activity errors of ${\sim}40\%$, but obtained source separation distances accurate to within $15$ cm. We also compare our APSL results against traditional Maximum Likelihood-Expectation Maximization (ML-EM) reconstructions, and demonstrate improved image accuracy and interpretability using APSL over ML-EM. These results indicate that APSL is capable of accurately reconstructing gamma-ray source positions and activities using measurements from existing detector hardware.

description: When attempting to measure gun ownership in the United States, the
problem of missing administrative data arises, making it necessary to find a
valid proxy. Several such proxies are employed in economic studies, one of
which is the fraction of “suicides by firearm” of “all suicides” (FSS). My work
validates this proxy from out-of-sample data, namely, Austrian administrative
data on firearm licenses. I also reevaluate, with appropriate statistical
methods, a result on firearms and suicide from the medical that is often used
for public policy advocacy. This result is, unfortunately, heavily biased due
to ignoring a well-known fallacy and thus can be only partially confirmed.
The audible space : attuning the Orpheum in downtown Vancouver

description: We live in a culture that readily and pervasively privileges the eye over the ear. Architecture is regarded increasingly as picturesque images by spectators at distance and in isolation. Building starts to lose their plasticity and the close connection with the language and wisdom of the body. However, every touching experience of architecture is multi-sensory. Therefore, architecture involves seven realms of sensory experiences which interact and infuse each other in a continuum. The thesis attempts to locate at the aural realm as a theoretical departure point and to explore ways of counterbalancing the unconscious tendency concerning retinal dominance. It is intended to recapture the fading sensuality, tactility and embodied essence of architecture. The study of audible space corresponds to one specific perceptual phenomenon as the starting point. This is not intended slightly to undermine the reality mat in architectural synthesis, different sensory categories overlap. The experiment attempts to explore and reinstate the relationship between architecture and sound. It seeks to trace for the seams which tie together their adjacencies and to overhear the different mutations of visual sound and acoustical space. Concepts and methodologies that signify the role of sound in architectural and environmental design will be investigated. The project, hypothetically the extension of the Orpheum Theater, will serve as the vehicle for the petrifying the theoretical investigation.. The project attempts to discover room and potential for improvements between the conflicting forces. The locale's charm lies in its specificity and complexity as an enduring historical local musical precinct, a neighborhood of depopulated and deteriorating street life. The study at this particular locale also tries to scrutinize the architectural relationship between the old and new and the possible regain of eminent public activities in public spaces resultant from inappropriate urban planning strategy.

description: This paper empirically analyzes the determinants of individual tourism-related adaptation to climate change, i.e. the stated choice of alternative travel destina-tions due to increasing temperatures in the future. By examining the tourism sector, our study investigates an industry which was not extensively considered in economic analyses of climate change so far in spite of its worldwide huge eco-nomic relevance and strong sensitivity to global warming. Our empirical analysis on the basis of unique representative data from 5370 German tourists first re-veals a non-negligible extent of tourism-related adaptation to climate change in the amount of more than 22% of the respondents. Our micro-econometric analysis with binary probit models implies strong positive effects of a high awareness of climate change effects, increasing age as indicator for vulnerability of climate change, as well as a high adaptive capacity (measured by disposable financial resources) on this type of adaptation. The estimation results suggest no single significant effect of a high educational level or a high level of information on ad-aptation to climate change, but a positive interaction effect (which was, in con-trast to former studies, estimated according to Ai and Norton 2003 and Norton et al. 2004). Our empirical results underline several challenges for the tourism in-dustry and policy makers in order to transform the tourism infrastructure and to diversify holiday offers. They additionally reveal important focus groups of tour-ists such as (the increasing group of) elderly persons who are crucial for the de-velopment of successful future product strategies in the tourism sector.

description: The frequency flicker of an oscillator, which appears as a 1/f^3 line in the phase noise spectral density, and as a floor on the Allan variance plot, originates from two basic phenomena, namely: (1) the 1/f phase noise turned into 1/f frequency noise via the Leeson effect, and (2) the 1/f fluctuation of the resonator natural frequency. The discussion on which is the dominant effect, thus on how to improve the stability of the oscillator, has been going on for years without giving a clear answer. This article tackles the question by analyzing the phase noise spectrum of several commercial oscillators and laboratory prototypes, and demonstrates that the fluctuation of the resonator natural frequency is the dominant effect. The investigation method starts from reverse engineering the oscillator phase noise in order to show that if the Leeson effect was dominant, the resonator merit factor Q would be too low as compared to the available technology.

description: We consider the problem of optimizing expensive black-box functions over discrete spaces (e.g., sets, sequences, graphs). The key challenge is to select a sequence of combinatorial structures to evaluate, in order to identify high-performing structures as quickly as possible. Our main contribution is to introduce and evaluate a new learning-to-search framework for this problem called L2S-DISCO. The key insight is to employ search procedures guided by control knowledge at each step to select the next structure and to improve the control knowledge as new function evaluations are observed. We provide a concrete instantiation of L2S-DISCO for local search procedure and empirically evaluate it on diverse real-world benchmarks. Results show the efficacy of L2S-DISCO over state-of-the-art algorithms in solving complex optimization problems.

Logistic regression

description: School shootings are often used in public policy debate as a justification for increased regulation, based on qualitative arguments. However, to date, no effort has been made to find valid qualitative arguments. However, to date, no effort has been made to find valid quantitative evidence for the claims bolstering the regulation recommendations. In defense of this absence of evidence, it is usually argued that the rarity of such events does not allow the employment of quantitative methods. This paper, using a simulation study, shows that, based on the number of shool shootings in the United States and Germany combined, the well-known method of logistic regression can be applied to a case-control study, making it possible to at least test for an association between hypothesized influential variables and the occurrences. Moderate relative risks, explained by an observed variable, would lead to a high power of appropriate test. A moderate number of cases generated by such a variable would suffice to show a significant association.

description: In this paper, we analyze the relationship between certain characteristics of incumbent central bank governors and their interest‐rate‐setting behavior. We focus on (i) occupational backgrounds, (ii) party affiliation, and (iii) experience in office and estimate augmented Taylor rules for 20 OECD countries and the period 1974–2008. Our findings are as follows. First, the tenures of central bank governors who are affiliated with a political party are characterized by a relatively dovish monetary policy stance, irrespective of their partisan ideology. Second, party affiliation appears to be more important than occupational background, i.e., all bankers with(out) a party affiliation behave very similarly to each regardless of their specific occupational background. Third, party members react significantly less to inflation and more to output the longer they stay in office.

description: Path-integral ab initio molecular dynamics (PI-AIMD) calculations have been employed to probe the nature of chloride ion solvation in aqueous solution. Nuclear quantum effects (NQEs) are shown to weaken hydrogen bonding between the chloride anion and the solvation shell of water molecules. As a consequence, the disruptive effect of the anion on the solvent water structure is significantly reduced compared to what is found in the absence of NQEs. The chloride hydration structure obtained from PI-AIMD agrees well with information extracted from neutron scattering data. Inparticular, the observed satellite peak in the hydrogen-chloride-hydrogen triple angular distribution serves as a clear signature of NQEs. The present results suggest that NQEs are likely to play acrucial role in determining the structure of saline solutions.

description: Abstract

Understanding the risks associated with soil erosion and drainage patterns is essential for agricultural output. In the research 9 sub-watersheds of the Bennihalla catchment located in semi-arid regions is studied to priorities for soil erosion-threat through morphometric investigation with the help of Geospatial methods and weighted sum approaches (WSA). ArcGIS was used to build drainage networks; SRTM DEM to delineate sub-watersheds and morphometric parameters (linear, relief and area) following standard formulas. The said parameters used to rank and prioritize sub-watersheds. A weighted sum approach (WSA) and cross-correlation of 18 morphometric parameters were used to approximate the compound factor. The compound factors for various sub-watersheds ranged from 0.0052 to 4.412. Lowest compound factor was given the highest priority. Sub-watersheds were classified as very good, good, moderate, low, and very low according to their compound factor value. The results indicated that, SW1 and SW 9 are influenced by respectively lowest and highest soil erosion threats, the other sub watershed that also need. Soil conservation measures include .SW7, and SW5 (1980.67 km2 area).

description: We present Spitzer observations at 3.6 and 4.5 microns and a near-infrared IRTF SpeX spectrum of the irradiated brown dwarf NLTT5306B. We determine that the brown dwarf has a spectral type of L5 and is likely inflated, despite the low effective temperature of the white dwarf primary star. We calculate brightness temperatures in the Spitzer wavebands for both the model radius, and Roche Lobe radius of the brown dwarf, and conclude that there is very little day-night side temperature difference. We discuss various mechanisms by which NLTT5306B may be inflated, and determine that while low mass brown dwarfs (M<35 MJup) are easily inflated by irradiation from their host star, very few higher mass brown dwarfs are inflated. The higher mass brown dwarfs that are inflated may be inflated by magnetic interactions or may have thicker clouds.

description: The shape and alignment of silver nanoparticles embedded in a glass matrix is controlled using silicon ion irradiation. Symmetric silver nanoparticles are transformed into anisotropic particles whose larger axis is along the ion beam. Upon irradiation, the surface plasmon resonance of symmetric particles splits into two resonances whose separation depends on the fluence of the ion irradiation. Simulations of the optical absorbance show that the anisotropy is caused by the deformation and alignment of the nanoparticles, and that both properties are controlled with the irradiation fluence.

description: This study considers the factors behind municipality amalgamations in Japan from fiscal year 1999 to 2005 using event history analysis. We use discrete-time logit model and 21,165 parson-year data. Our findings show that the central government’s “carrot and stick” policy strongly influenced municipality amalgamations for those with high ratios of inter-governmental grants to total revenue. Moreover, neighboring municipalities became the trigger for the amalgamation of other municipalities.

description: Using the Keck Interferometer, we spatially resolved the orbit of the pre-main sequence binary, Haro 1-14c, for the first time. We present these interferometric observations along with additional spectroscopic radial velocity measurements of the components. We performed a simultaneous orbit fit to the interferometric visibilities and the radial velocities of Haro 1-14c. Based on a statistical analysis of the possible orbital solutions that fit the data, we determined component masses of M_1 = 0.96 (+0.27/-0.08) Msun and M_2 = 0.33 (+0.09/-0.02) Msun for the primary and secondary, respectively, and a distance to the system of 111 (+19/-18) pc. The distance measurement is consistent with the close distance estimates of the Ophiuchus molecular cloud. Comparing our results with evolutionary tracks suggests an age of 3-4 Myr for Haro 1-14c. With additional interferometric measurements to improve the uncertainties in the masses and distance, we expect the low-mass secondary to provide important empirical data for calibrating the theoretical evolutionary tracks for pre-main sequence stars.

description: This paper uses survival analysis to examine the time taken to carry out municipality amalgamation in Japan in terms of both forming the amalgamation committee and completing amalgamation. The results show that municipalities that depend on localm allocation tax grants as a revenue source, those that have an incentive to become a city that has special administrative discretions, and those that jointly manage local services form a committee and complete amalgamation more quickly. Further, municipalities that have high local public debt tend not to form committees. These findings show that the central government’s “carrot-and-stick” policy has strongly influenced municipality amalgamation.

description: © 2014 Ji et al. Secreted microRNAs (miRNAs) enclosed within extracellular vesicles (EVs) play a pivotal role in intercellular communication by regulating recipient cell gene expression and affecting target cell function. Here, we report the isolation of three distinct EV subtypes from the human colon carcinoma cell line LIM1863 - shed microvesicles (sMVs) and two exosome populations (immunoaffinity isolated A33-exosomes and EpCAM-exosomes). Deep sequencing of miRNA libraries prepared from parental LIM1863 cells/derived EV subtype RNA yielded 254 miRNA identifications, of which 63 are selectively enriched in the EVs - miR-19a/b-3p, miR-378a/c/d, and miR-577 and members of the let-7 and miR-8 families being the most prominent. Let-7a-3p∗, let-7f-1-3p∗, miR-451a, miR-574-5p∗, miR-4454 and miR-7641 are common to all EV subtypes, and 6 miRNAs (miR-320a/b/c/d, miR-221-3p, and miR-200c-3p) discern LIM1863 exosomes from sMVs; miR-98-5p was selectively represented only in sMVs. Notably, A33-Exos contained the largest number (32) of exclusively-enriched miRNAs; 14 of these miRNAs have not been reported in the context of CRC tissue/biofluid analyses and warrant further examination as potential diagnostic markers of CRC. Surprisingly, miRNA passenger strands (star miRNAs) for miR-3613-3p∗, -362-3p∗, -625-3p∗, -6842-3p∗ were the dominant strand in A33-Exos, the converse to that observed in parental cells. This finding suggests miRNA biogenesis may be interlinked with endosomal/exosomal processing.
