description: We present high angular resolution observations of the HCN(1-0) emission (at ~1" or ~34 pc), together with CO J = 1-0, 2-1, and 3-2 observations, toward the Seyfert 2 nucleus of M51 (NGC 5194). The overall HCN(1-0) distribution and kinematics are very similar to that of the CO lines, which have been indicated as the jet-entrained molecular gas in our past observations. In addition, high HCN(1-0)/CO(1-0) brightness temperature ratio of about unity is observed along the jets, similar to that observed at the shocked molecular gas in our Galaxy. These results strongly indicate that both diffuse and dense gases are entrained by the jets and outflowing from the AGN. The channel map of HCN(1-0) at the systemic velocity shows a strong emission right at the nucleus, where no obvious emission has been detected in the CO lines. The HCN(1-0)/CO(1-0) brightness temperature ratio at this region reaches >2, a value that cannot be explained considering standard physical/chemical conditions. Based on our calculations, we suggest infrared pumping and possibly weak HCN masing, but still requiring an enhanced HCN abundance for the cause of this high ratio. This suggests the presence of a compact dense obscuring molecular gas in front of the nucleus of M51, which remains unresolved at our ~1" (~34 pc) resolution, and consistent with the Seyfert 2 classification picture.

description: This study aims to verify the relationship between of social exclusion of older people living in rural areas and their depression, taking experiences of discrimination into consideration, as a meditated effect. Data from a survey taken from 800 elderly people, 65 years old and older and living in rural areas, were used. Frequency analysis, descriptive statistical analysis, and path analysis were conducted using STATA13 and MPLUS 7. Based on the results of path analysis, medical exclusion did not directly affect depression, except when mediated by experiences of discrimination. Lifelong education exclusion and material exclusion had a direct influence on depression. Residential exclusion not only directly affected depression, it was also influential when mediated by experiences of discrimination. Results suggested policies and interventions to prevent the incidence of depression incurred by social exclusion of the elderly in rural areas.

description: This article explores how trauma theory has become influential in recent years in the fields of child welfare, out-of-home care and youth justice. It argues that this has brought with it some serious concerns. These include a belief that trauma informed approaches provide the answer to most or even all the challenges faced in human service delivery and that it applies equally across a diverse range of clients. There is also a lack of clarity about the definitions and nature of trauma including the conflation of different types of adversity, and some evidence of rigid, unthinking applications of theory, research findings and clinical propositions.

description: The angiotensinogen M235T polymorphism in humans is linked to differential expression of the human angiotensinogen gene (AGT) gene and hypertension, but the homeostatic responses resulting from this polymorphism are not known. We therefore investigated how mice respond to five genetically determined levels of mouse angiotensinogen gene (Agt) expression covering the range associated with the M235T variants. By using high-throughput molecular phenotyping, tissue RNAs were assayed for expression of 10 genes important in hypertension. Significant positive and negative responses occurred in both sexes as Agt expression increased twofold, including a three-fold increase in aldosterone synthase expression in adrenal gland, and a two-fold decrease in renin expression in kidney. In males, cardiac expression of the precursor of atrial natriuretic peptide B and of adrenomedullin also increased approximately twofold. The relative expression of all genes studied except Agt differed significantly in the two sexes, and several unexpected relationships were encountered. A highly significant correlation between renal expression of the angiotensin type 1a receptor and kallikrein, independent of Agt genotype, is present in females (P < 0.0001) but not males (P = 0.4). The correlation between blood pressure (BP) and liver Agt expression within the five Agt genotypes is significant in females (P = 0.0005) but not in males (P = 0.2), whereas correlation of BP with differences between the genotypes is less in females (P = 0.06) than in males (P = 0.001). The marked gender differences in gene expression in wild-type mice and the changes induced by moderate alterations in Agt expression and BP emphasize the need to look for similar differences in humans.

description: The long-term effect of exposure to DNA alkylating agents is entwined with the cell's genetic capacity for DNA repair and appropriate DNA damage responses. A unique combination of environmental exposure and deficiency in these responses can lead to genomic instability; this “gene–environment interaction” paradigm is a theme for research on chronic disease etiology. In the present study, we used mouse embryonic fibroblasts with a gene deletion in the base excision repair (BER) enzymes DNA β-polymerase (β-pol) and alkyladenine DNA glycosylase (AAG), along with exposure to methyl methanesulfonate (MMS) to study mutagenesis as a function of a particular gene–environment interaction. The β-pol null cells, defective in BER, exhibit a modest increase in spontaneous mutagenesis compared with wild-type cells. MMS exposure increases mutant frequency in β-pol null cells, but not in isogenic wild-type cells; UV light exposure or N-methyl-N′-nitro-N-nitrosoguanidine exposure increases mutant frequency similarly in both cell lines. The MMS-induced increase in mutant frequency in β-pol null cells appears to be caused by DNA lesions that are AAG substrates, because overexpression of AAG in β-pol null cells eliminates the effect. In contrast, β-pol/AAG double null cells are slightly more mutable than the β-pol null cells after MMS exposure. These results illustrate that BER plays a role in protecting mouse embryonic fibroblast cells against methylation-induced mutations and characterize the effect of a particular combination of BER gene defect and environmental exposure.

description: To diversify the agricultural exports of Korea, this study selected Mongolia, which is located closest to China, as a sampling area and sought ways to promote the export of fresh agricultural products to Mongolia. This study analyzed the contributing factors to the export, such as Mongolian consumers’ purchasing intentions, as well as the purchasing price of fresh Korean products in Mongolia, using the Heckman two stage correction model. Based on the results of the analysis, this study suggested the following policy implications. First, Mongolian consumers’ intention of purchasing fresh Korean produce was higher when consumers were younger in age, from a bigger city, had higher income, or had any past experience visiting Korea. Therefore, it was is necessary to understand the demographic characteristics of Mongolian consumers and then actively use niche marketing strategies. Second, the purchase intention of Mongolian consumers towards fresh Korean produce increased when buying behavior occurred in department stores rather than traditional markets. Hence, we proposed a strategy for fresh Korean products to prioritize sales locations; department stores and traditional markets. Third, it was necessary to seek ways for reducing the price of fresh Korean produce, which was too high in Mongolia due to high air transportation costs.
Nonlinear partial differential equations and applications: Gene expression profiling of isogenic cells with different TP53 gene dosage reveals numerous genes that are affected by TP53 dosage and identifies CSPG2 as a direct target of p53

description: TP53 does not fully comply with the Knudson model [Knudson, A. G., Jr. (1971) Proc. Natl. Acad. Sci. USA 68, 820–823] in that a reduction of constitutional expression of p53 may be sufficient for tumor predisposition . This finding suggests a gene-dosage effect for p53 function. To determine whether TP53 gene dosage affects the transcriptional regulation of target genes, we performed oligonucleotide-array gene expression analysis by using human cells with wild-type p53 (p53 +/+), or with one (p53 +/−), or both (p53 −/−) TP53 alleles disrupted by homologous recombination. We identified 35 genes whose expression is significantly correlated to the dosage of TP53. These genes are involved in a variety of cellular processes including signal transduction, cell adhesion, and transcription regulation. Several of them are involved in neurogenesis and neural crest migration, developmental processes in which p53 is known to play a role. Motif search analysis revealed that of the genes highly expressed in p53 +/+ and +/− cells, several contain a putative p53 consensus binding site (bs), suggesting that they could be directly regulated by p53. Among those genes, we chose CSPG2 (which encodes versican) for further study because it contains a bona fide p53 bs in its first intron and its expression highly correlates with TP53 dosage. By using in vitro and in vivo assays, we showed CSPG2 to be directly transactivated by p53. In conclusion, we developed a strategy to demonstrate that many genes are affected by TP53 gene dosage for their expression. We report several candidate genes as potential downstream targets of p53 in nonstressed cells. Among them, CSPG2 is validated as being directly transactivated by p53. Our method provides a useful tool to elucidate additional mechanisms by which p53 exerts its functions.

description: Mammalian sulfoglycolipids comprise two major members, sulfatide (HSO3-3-galactosylceramide) and seminolipid (HSO3-3-monogalactosylalkylacylglycerol). Sulfatide is a major lipid component of the myelin sheath and serves as the epitope for the well known oligodendrocyte-marker antibody O4. Seminolipid is synthesized in spermatocytes and maintained in the subsequent germ cell stages. Both sulfoglycolipids can be synthesized in vitro by using the isolated cerebroside sulfotransferase. To investigate the physiological role of sulfoglycolipids and to determine whether sulfatide and seminolipid are biosynthesized in vivo by a single sulfotransferase, Cst-null mice were generated by gene targeting. Cst−/− mice lacked sulfatide in brain and seminolipid in testis, proving that a single gene copy is responsible for their biosynthesis. Cst−/− mice were born healthy, but began to display hindlimb weakness by 6 weeks of age and subsequently showed a pronounced tremor and progressive ataxia. Although compact myelin was preserved, Cst−/− mice displayed abnormalities in paranodal junctions. On the other hand, Cst−/− males were sterile because of a block in spermatogenesis before the first meiotic division, whereas females were able to breed. These data show a critical role for sulfoglycolipids in myelin function and spermatogenesis.

Pheromone induction promotes Ste11 degradation through a MAPK feedback and ubiquitin-dependent mechanism
Creators: name: Errede, B.
name: Esch, R. K.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: Ste11 is the mitogen-activated protein kinase (MAPK) kinase kinase in the MAPK cascades that mediate mating, high osmolarity glycerol, and filamentous growth responses in Saccharomyces cerevisiae. We show stimulation of the mating pathway by pheromone promotes an accelerated turnover of Ste11 through a MAPK feedback and ubiquitin-dependent mechanism. This degradation is pathway specific, because Ste11 is stable during activation of the high osmolarity glycerol pathway. Because the steady-state amount of Ste11 does not change significantly during pheromone induction, we infer that maintenance of MAPK activation involves repeated cycles in which naïve Ste11 is activated and then targeted for degradation. This model predicts that elimination of active Ste11 would rapidly curtail MAPK activation upon attenuation of the upstream signal. This prediction is confirmed by the finding that blocking ubiquitin-dependent Ste11 degradation during pheromone induction abolishes the characteristic attenuation profile for MAPK activation.

description: The measurement of the deflection of starlight during a total solar eclipse on May 29, 1919 was the first verification of general relativity by an external team of scientists, brought Einstein and his theory to the attention of the general public, and left a legacy of experimental testing that continues today. The discovery of gravitational lenses turned Einstein's deflection into an important tool for astronomy and cosmology. This article reviews the history of the 1919 measurement and other eclipse measurements, describes modern measurements of the effect using radio astronomy, and of its cousin, the Shapiro time delay, and discusses gravitational lenses.

description: The ATR protein is a member of the phosphoinositide 3-kinase-related kinase family and plays an important role in UV-induced DNA damage checkpoint response. Its role as a signal transducer in cell cycle checkpoint is well established, but it is currently unclear whether ATR functions as a damage sensor as well. Here we have purified the ATR protein and investigated its interaction with DNA by using biochemical analysis and electron microscopy. We find that ATR is a DNA-binding protein with higher affinity to UV-damaged than undamaged DNA. In addition, damaged DNA stimulates the kinase activity of ATR to a significantly higher level than undamaged DNA. Our data suggest that ATR may function as an initial sensor in the DNA damage checkpoint response.

description: This study analyzes changes in the profitability and productivity of Korean rice farms. Also we decomposes changes in the profitability into changes in terms-of-trade, technical change, technical efficiency change, scale efficiency change and mix efficiency change. To be specific, we constructs Lowe index which is ideal for the measurement of quantity change. Also, we apply data envelopment analysis methodology for decomposing TFP into the several efficiency measures. Farm production cost survey covering the period 2003 to 2016 is incorporated. The results show that the terms-of-trade would have the largest and negative effects on farms’ profitability. Also, rice farms in Korea are technically efficient, but they exhibited much lower mix efficiency. Lastly, farm operator’s age would have negative effects on farms’ mix efficiency, while larger farms tend to have greater mix efficiencies than smaller farms.

description: In prior work we introduced a pure type assignment system that encompasses a rich set of property types, including intersections, unions, and universally and existentially quantified dependent types. This system was shown sound with respect to a call-by-value operational semantics with effects, yet is inherently undecidable. In this paper we provide a decidable formulation for this system based on bidirectional checking, combining type synthesis and analysis following logical principles. The presence of unions and existential quantification requires the additional abiity to visit subterms in evaluation position before the context in which they occur, leading to a tridirectional type system. While soundness with respect to the type assignment system is immediate, completeness requires the novel concept of contextual type annotations, introducing a notion from the study of principal typings into the source program.

description: We propose a new antenna configuration of a torsion-bar antenna (TOBA) and study its performance. A TOBA is a novel type of an antenna for low-frequency gravitational waves (GWs) which consists of two bar-shaped orthogonal test masses. Previously only the rotation of the bars on the horizontal plane had been considered as output signals. In this paper, we introduce a new antenna configuration for a TOBA to incorporate two additional outputs by measuring the rotation of the bars on the vertical planes. Such a triple-output TOBA can be regarded as a network of three coincident but misaligned interferometric detectors. We investigate its event detection rate and its parameter accuracies using Fisher analysis. We find that since the triple-output TOBA can discriminate two polarization modes of a short-duration GW signal even with a single antenna thanks to having three independent outputs, it improves the detection rate and the accuracies of waveform parameters drastically.

description: Pre-mRNA splicing takes place in a large and highly dynamic complex known as the spliceosome. Here we report the optimization of a maltose-binding protein (MBP) affinity-purification method to isolate functional spliceosomes for electron microscopic analysis. Visualization of the spliceosome preparations revealed distinct 40–60 nm particles. Immunogold-conjugated antibodies to spliceosome components specifically label these particles, which are eliminated by treatment with either RNase or protease. Moreover, spliceosomes assembled on two different pre-mRNAs are indistinguishable. This first visualization of purified functional spliceosomes assembled in vitro reveals striking structural features, including one or more central cavities and multiple elongate lobes.

The recent FOPI data for the $^3$H$/$$^3$He ratio are compared with UrQMD calculations using 13 Skyrme interactions (all exhibiting similar values of iso-scalar incompressibility but very different density dependences of the symmetry energy). It is found that the $^3$H$/$$^3$He ratio is sensitive to the nuclear symmetry energy at sub-saturation densities. Model calculations with moderately soft to linear symmetry energies are in agreement with the experimental FOPI data. This result is in line with both, the recent constraints on the low-density symmetry energy available in the literature and our previous results for the high-density symmetry energy obtained with the elliptic flow of free nucleons and hydrogen isotopes as a sensitive probe.

description: We investigate hierarchical structures of the European countries by using debt as a percentage of Gross Domestic Product (GDP) of the countries as they change over a certain period of time. We obtain the topological properties among the countries based on debt as a percentage of GDP of European countries over the period 2000-2011 by using the concept of hierarchical structure methods (minimal spanning tree, (MST) and hierarchical tree, (HT)). This period is also divided into two sub-periods related to 2004 enlargement of the European Union, namely 2000-2004 and 2005-2011, in order to test various time-window and observe the temporal evolution. The bootstrap techniques is applied to see a value of statistical reliability of the links of the MSTs and HTs. The clustering linkage procedure is also used to observe the cluster structure more clearly. From the structural topologies of these trees, we identify different clusters of countries according to their level of debts and economic ties. Our results show that by the debt crisis, the less and most affected Eurozones economies are formed as a cluster with each other in the MSTs and hierarchical trees.

description: Are work values a cause (Weber) or consequence (Marx) of the economic environment? The collapse of the Soviet Union at the end of 1991 provides a unique opportunity to investigate this link. Using data collected from an employee survey conducted in over 340 workplaces in Armenia, Azerbaijan and Russia, we investigate generational differences in adherence to the Protestant work ethic (PWE). Our results indicate that Marx was 'right' about the link between work values and economic environment. That is, despite economic and cultural differences emerging during the transformation process, in all three countries, participating workers born after 1981 adhere more strongly to PWE than workers born before 1977. Moreover, the estimate magnitudes are very similar across these economically and culturally diverse countries. More generally, PWE adherence is stronger among participating workers with an internal locus of control and among supervisors. PWE adherence also tends to be stronger among participants with high relative earnings, as well as among those working in organizations that reward hard work with the chance to develop new skills or learn new things. © 2013 Elsevier B.V.

description: FtsZ, the major cytoskeletal component of the bacterial cell-division machine, assembles into a ring (the Z-ring) that contracts at septation. FtsZ is a bacterial homolog of tubulin, with similar tertiary structure, GTP hydrolysis, and in vitro assembly. We used green fluorescent protein-labeled FtsZ and fluorescence recovery after photobleaching to show that the E. coli Z-ring is extremely dynamic, continually remodeling itself with a half-time of 30 s. ZipA, a membrane protein involved in cell division that colocalizes with FtsZ, was equally dynamic. The Z-ring of the mutant ftsZ84, which has 1/10 the guanosine triphosphatase activity of wild-type FtsZ in vitro, showed a 9-fold slower turnover in vivo. This finding implies that assembly dynamics are determined primarily by GTP hydrolysis. Despite the greatly reduced assembly dynamics, the ftsZ84 cells divide with a normal cell-cycle time.

Καθότι έχουν ήδη διεξαχθεί αρκετές μελέτες που αφορούν αυτόν τον τομέα, μικρός είναι ο αριθμός αυτών, οι οποίες ερευνούν της επιμέρους μεταβλητές του ESG Score και της επίδρασης τους στην χρηματοοικονομική αποδοτικότητα των επιχειρήσεων. Επίσης, προηγούμενες μελέτες έχουν προβεί σε ένα εύρος αποτελεσμάτων, για τα οποία υπάρχει η εξής κατηγοριοποίηση: η υπεύθυνη ή / και διαφανής λειτουργία των επιχειρήσεων έχει θετική επίδραση στη χρηματοοικονομική τους απόδοση, η υπεύθυνη ή / και διαφανής λειτουργία των επιχειρήσεων έχει αρνητική επίδραση στη χρηματοοικονομική τους απόδοση και η υπεύθυνη ή / και διαφανής λειτουργία των επιχειρήσεων δεν επηρεάζει καθόλου την χρηματοοικονομική τους απόδοση. Στην παρούσα μελέτη χρησιμοποιήθηκαν δεδομένα από 7.911 επιχειρήσεις όλων των κλάδων που δραστηριοποιούνται στην Ευρωπαϊκή Ένωση για την περίοδο 2004 – 2020. Όσον αφορά στη σύνθετη μεταβλητή ESG, φαίνεται πως αυτή επηρεάζει αρνητικά την απόδοση των επιχειρήσεων όπως αυτή μετράται με τα λογιστικά μέτρα, ενώ υπάρχει μη-γραμμική σχέση αντίστροφου U με την απόδοση των επιχειρήσεων όταν αυτή μετράται με τα χρηματιστηριακά μέτρα. Επιπροσθέτως, για την Εταιρική Κοινωνική Ευθηνή (CSR) βρέθηκε μη-γραμμική σχέση αντίστροφου U με την λογιστική αλλά και χρηματιστηριακή απόδοση των επιχειρήσεων. Τέλος, όσον αφορά στην επίδραση της διαφανούς λειτουργίας των επιχειρήσεων, βρέθηκε αρνητική επίδραση στην χρηματοοικονομική απόδοσης τους.

description: More and more states have passed laws that allow individuals to use marijuana for medical purposes. There is an ongoing, heated policy debate over whether these laws have increased marijuana use among non-patients. In this paper, I address that question empirically by studying marijuana possession arrests in cities from 1988 to 2008. I estimate fixed effects models with city-specific time trends that can condition on unobserved heterogeneities across cities in both their levels and trends. I find that these laws increase marijuana arrests among adult males by about 15-20%. These results are further validated by findings from data on treatment admissions to rehabilitation facilities: marijuana treatments among adult males increased by 10-20% after the passage of medical marijuana laws.

description: The parent article (Gosselin (2022)) introduces the Euclidean scattering coefficient (ESC), a new statistical tool that captures the denseness of the data, adjusted to amplify the possible existence of multimodality. ESC is tailored to large multivariate samples and might open avenues in fields as diverse as precision medicine, ecology, and econometrics.
 This Figshare data support the article by providing supplemental figures, R codes corresponding to simulations in figures/supplemetal figures and the appendix that describes the asymptotic limit of ESC in biveariate data as the intermodal distance increases.
Searching for dilepton resonances below the Z mass at the LHC

description: We consider LHC searches for dilepton resonances in an intermediate mass range, $\sim 10 -80$ GeV. We adopt a kinetically mixed $Z'$ as an example of weakly coupled new physics that might have evaded detection at previous experiments but which could still be probed by LHC dilepton spectrum measurements in this mass range. Based on Monte Carlo simulations, we estimate that existing data from the 7 and 8 TeV LHC could be used to test values of the kinetic mixing parameter $ε$ several times smaller than precision electroweak upper bounds, were an appropriate analysis to be carried out by one of the experimental collaborations.

DESIRED: A database of high-quality spectra to study fundamental problems in ionized nebulae
Creators: name: García-Rojas, Jorge
Publisher: name: Zenodo
Year: 2024

description: We present preliminary results based on a homogeneous analysis of the DEep Spectra of Ionized REgions Database (DESIRED), a compilation of high signal-to-noise ratio optical spectra of photoionized nebulae. The database comprises more than 1800 spectra of Galactic and extragalactic HII regions and H II galaxies, and more than 200 spectra of planetary nebulae (PNe), as well as other photoionized nebulae such as ring nebulae or Herbig-Haro objects. The analysis of a first reduced version (190 objects) of this database has revealed important implications for various astrophysical problems, such as the presence of temperature fluctuations to explain the abundance discrepancy problem in HII regions (Méndez-Delgado et al. 2023a), or the effects of electron density inhomogeneities on the temperature structure of the nebulae (Méndez-Delgado et al. 2023b). In this poster, we focus on the potential of DESIRED to address some open problems in chemical abundances in PNe.
Structural and elastic properties of a confined 2D colloidal solid: a molecular dynamics study

description: We implement molecular dynamics simulations in canonical ensemble to study the effect of confinement on a $2d$ crystal of point particles interacting with an inverse power law potential proportional to $r^{-12}$ in a narrow channel. This system can describe colloidal particles at the air-water interface. It is shown that the system characteristics depend sensitively on the boundary conditions at the two {\it walls} providing the confinement. The walls exert perpendicular forces on their adjacent particles. The potential between walls and particles varies as the inverse power of ten. Structural quantities such as density profile, structure factor and orientational order parameter are computed. It is shown that orientational order persists near the walls even at temperatures where the system in the bulk is in fluid state. The dependence of elastic constants, stress tensor elements, shear and bulk modulii on density as well as the channel width is discussed. Moreover, the effect of channel incommensurability with the triangular lattice structure is discussed. It is shown that incommensurability notably affects the system properties. We compare our findings to those obtained by Monte Carlo simulations and also to the case with the periodic boundary condition along the channel width. .

Recruitment of intron-encoded and co-opted proteins in splicing of the bI3 group I intron RNA

description: Detectable splicing by the Saccharomyces cerevisiae mitochondrial bI3 group I intron RNA in vitro is shown to require both an intron-encoded protein, the bI3 maturase, and the nuclear-encoded protein, Mrs1. Both proteins bind independently to the bI3 RNA. The bI3 maturase binds as a monomer, whereas Mrs1 is a dimer in solution that assembles as two dimers, cooperatively, on the RNA. The active six-subunit complex has a molecular mass of 420 kDa, splices with a kcat of 0.3 min−1, and binds the guanosine nucleophile with an affinity comparable to other group I introns. The functional bI3 maturase domain is translated from within the RNA that encodes the intron, has evolved a high-affinity RNA-binding activity, and is a member of the LAGLIDADG family of DNA endonucleases, but appears to have lost DNA cleavage activity. Mrs1 is a divergent member of the RNase H fold superfamily of dimeric DNA junction-resolving enzymes that also appears to have lost its nuclease activity and now functions as a tetramer in RNA binding. Thus, the bI3 ribonucleoprotein is the product of a process in which a once-catalytically active RNA now obligatorily requires two facilitating protein cofactors, both of which are compromised in their original functions.

description: Although consumers take the use of foods into account when they make purchase decisions, most studies on food consumption have analyzed food demand only by food items without considering it. For accurate analysis on food purchase behavior, it is necessary to classify and analyze foods according to their uses. This study estimated processed food demand in Korea by using the UDAIDS (Usage Differentiated AIDS) model and the data of household account books. Also, it conducted a comparative analysis on the estimation results from the AIDS model and the UDAIDS model. Through the analysis, it found that a food demand analysis using the latter produces more accurate results.
