description: The research examined effect of climate variability on yield of the two dominant cool weather cereals (wheat and barley) in central highland and Arssi grain plough farming systems of Ethiopia using eight round unbalanced panel data (1994-2014). The stochastic frontier model result revealed that production inputs for producing wheat and barley in the two farming system had significant effect. Crop season rainfall increment had negative and significant effect on technical efficiency of smallholders to produce wheat as to the model result. Technical efficiency of two crops responded differently for cropping season rainfall variability, in which wheat had negative and significant interaction with it while barley had positive. Given this, cropping season temperature had significant and positive effect on technical efficiency of both wheat and barley. Having this into account, yield of the two crops responded similarly for changes in production inputs like working capital, human labor and fertilizer. In general, rainfall inconsistency at the different stages of the production period had strong effect on yield of the two crops. Given this, the study forwarded an assignment to plant scientists in order to have further investigation on how the two crops responded differently to temperature variability.

description: Rice plays an especial role in Iranian households' nutrition basket. The volatilities of its price during recent years caused consumers' dissatisfaction. This paper investigates spillover effects of price volatilities (at the wholesale and retail levels) in the Guilan Province rice market. The Generalized Autoregressive Conditional Hetroscedasitic (GARCH) model was used for the monthly time period of 1999 to 2013. As the results of the unit root tests showed, the monthly time series of Sadri-Momtaz variety wholesale price and Sadri-Momtaz variety retail price have unit roots in zero frequency or they are I(1). Considering the amounts of trace and maximum eigen values statistics, there is a long-run relationship between Sadri- Momtaz variety wholesale and retail monthly price time series. Coefficients of normalized cointegration vector showed that, with one percent increase (decrease) in retail price, it would be likely that wholesale price could increase (decrease) by 0.99 percent. Results of GRACH model revealed that spillover effects exist from the retail price to the wholesale price and vice versa. In addition, price volatility in retail and wholesale levels had positive and significant effects on its own level price volatility. Accordingly, providing proper policy packages in both supply and demand sides were advised.

description: Following the method already developed for studying the actions of GL_q(2,C) on the Clifford algebra C(1,3) and its quantum invariants (Commun. in Algebra 27, 1843-1878(1999)), we study the action on C(1,3) of the quantum group GL_2 constructed by Dipper and Donkin. We are able of proving that there exists only two non-equivalent cases of actions with nontrivial "perturbation". The space of invariants are trivial in both cases. We also prove that each irreducible finite dimensional algebra representation of the quantum group GL_2, q^m\neq 1, is one dimensional. By studying the cases with zero "perturbation" we find that the cases with nonzero "perturbation" are the only ones with maximal possible dimension for the operator algebra \Re.

description: In this study, musculoskeletal disorders, energy consumption and input costs of paddy labors have been studied in cultivation, crop protection, and harvesting rice in Northern Iran, Guilan province. The sample size of the study consisted of 74 paddy workers of the study region. The data were collected through Nordic questionnaire and semi-structured interviews. The results indicated that the labor input energy of cultivation, crop protection, and harvesting were 674.6, 356.8 and 205.9 MJha-1, respectively. The total labor input costs were determined to be 22,860,000 IRRs ha-1. Lower back, back and knees were the most common areas where paddy workers were feeling pain. There were significant differences among the age, working hours and working years of healthy and relatively healthy poor paddy workers (p<0.01). One-fifth of the selected farmers self-reported that their health was at a very poor level. Overall, considering the relatively high costs and the different types of common musculoskeletal disorders related to rice cultivation in this province and also the side effects of using the painkillers in the working season, it is recommended to invest and accelerate the process of mechanization of rice farming in Guilan Province of Iran.

description: We present radiation-magnetohydrodynamic simulations aimed at studying evolutionary properties of H\,{\normalsize II} regions in turbulent, magnetised, and collapsing molecular clouds formed by converging flows in the warm neutral medium. We focus on the structure, dynamics and expansion laws of these regions. Once a massive star forms in our highly structured clouds, its ionising radiation eventually stops the accretion (through filaments) toward the massive star-forming regions. The new over-pressured H\,{\normalsize II} regions push away the dense gas, thus disrupting the more massive collapse centres. Also, because of the complex density structure in the cloud, the H\,{\normalsize II} regions expand in a hybrid manner: they virtually do not expand toward the densest regions (cores), while they expand according to the classical analytical result towards the rest of the cloud, and in an accelerated way, as a blister region, towards the diffuse medium. Thus, the ionised regions grow anisotropically, and the ionising stars generally appear off-centre of the regions. Finally, we find that the hypotheses assumed in standard H\,{\normalsize II}-region expansion models (fully embedded region, blister-type, or expansion in a density gradient) apply simultaneously in different parts of our simulated H\,{\normalsize II} regions, producing a net expansion law ($R \propto t^α$, with $α$ in the range of 0.93-1.47 and a mean value of $1.2 \pm 0.17$) that differs from any of those of the standard models.

description: Separation of glow stick dyes adhered to a cotton swab using liquid CO2 provides an engaging demonstration of several chemical concepts including polarity, kinetics, chemiluminescence, and the importance of CO2 a green solvent. The simple protocol allows access to a broad range of students. Differential polarities of the glow stick dyes allow certain dyes to be preferentially dissolved in liquid CO2, leaving other dyes adhered onto cotton. Both TCPO (bis(2,4,6-trichlorophenyl)oxalate) and H2O2, which together provide the necessary reaction for chemiluminescence, are present in both the extracted liquid and cotton upon dissipation of CO2. Thus, it is possible to compare the emission spectrum of the extracted fluid to that of the original glow stick and the residue left on the cotton swab. Emission peaks resulting from the presence of polar dyes in the original glow stick and on the cotton are routinely observed to be missing in the extracts.

description: We argue that an ionic lattice surrounded by a Fermi liquid changes phase several times under pressure, oscillating between the symmetric phase and a low-symmetry dimerized structure, as a consequence of Friedel oscillations in the pair potential. Phase oscillations explain the tendency towards dimerization which has been recently reported for the light alkali metals under high pressure. Moreover, a restoring of the symmetric phase is predicted for such elements at an even higher density.

description: For Einstein's General Relativity (GR) or the alternatives suggested up to date the vacuum energy gravitates. We present a model where a new measure is introduced for integration of the total action in the D-dimensional space-time. This measure is built from D scalar fields $φ_{a}$. As a consequence of such a choice of the measure, the matter lagrangian $L_{m}$ can be changed by adding a constant while no gravitational effects, like a cosmological term, are induced. Such Non-Gravitating Vacuum Energy (NGVE) theory has an infinite dimensional symmetry group which contains volume-preserving diffeomorphisms in the internal space of scalar fields $φ_{a}$. Other symmetries contained in this symmetry group, suggest a deep connection of this theory with theories of extended objects. In general {\em the theory is different from GR} although for certain choices of $L_{m}$, which are related to the existence of an additional symmetry, solutions of GR are solutions of the model. This is achieved in four dimensions if $L_{m}$ is due to fundamental bosonic and fermionic strings. Other types of matter where this feature of the theory is realized, are for example: scalars without potential or subjected to nonlinear constraints, massless fermions and point particles. The point particle plays a special role, since it is a good phenomenological description of matter at large distances. de Sitter space is realized in an unconventional way, where the de Sitter metric holds, but such de Sitter space is supported by the existence of a variable scalar field which in practice destroys the maximal symmetry. The only space - time where maximal symmetry is not broken, in a dynamical sense, is Minkowski space. The theory has non trivial dynamics in 1+1 dimensions, unlike GR.

Nearly Overconvergent Forms and p-adic L-Functions for Symplectic Groups

Subjects: subject: Mathematics

description: We reformulate Shimura's theory of nearly holomorphic forms for Siegel modular forms using automorphic sheaves over Siegel varieties. This sheaf-theoretic reformulation allows us to define and study basic properties of nearly overconvergent Siegel modular forms as well as their p-adic families. Besides, it finds applications in the construction, via the doubling method, of p-adic partial standard L-functions associated to Siegel cuspidal Hecke eigensystems. We illustrate how the sheaf-theoretic definition of nearly holomorphic forms and Maass--Shimura differential operators helps with the choice of the archimedean sections for the Siegel Eisenstein series on the doubling group Sp(4n) and the study of the p-adic properties of their restrictions to Sp(2n)*Sp(2n). The selection of archimedean sections, together with p-adic interpolation considerations, then naturally gives the sections at the place p. We compute p-adic zeta integrals corresponding to those sections. Finally, we construct the p-adic standard L-functions associated to ordinary families of Siegel Hecke eigensystems and obtain their interpolation properties.
Selenium status : Elk River Valley, BC

Year: 2009

description: The status of investigations into the effects (changes to a Valued Ecosystem Component [VEC]) or impacts (effects adversely affecting the utility or viability of a VEC) of selenium in the Elk River Valley, BC are reviewed. Previous studies focused on the abundant lotic (flowing water) habitats in the Valley and found limited effects (reduced sandpiper egg hatchability) but no impacts (overall sandpiper productivity higher than the regional norm). More recent studies have focused on less abundant high-risk lentic areas where selenium effects are more likely. Effects studies have been conducted with: red-winged blackbirds; various waterfowl species; Columbia spotted frogs; longnosed suckers. Based on studies conducted to date, current levels of selenium in the Valley do not appear to be having large-scale negative effects or impacts. However, some negative effects do appear to be occurring on a more localized level in some of the high-risk lentic areas. Studies are underway to assess whether or not there are population-level impacts in these lentic areas and, if so, their extent and significance. The possibility of management actions will be assessed accordingly.

description: Analytic arguments and numerical simulations show that bosonic ultra-light dark matter (ULDM) would form cored density distributions (`solitons') at the center of galaxies. ULDM solitons offer a promising way to exclude or detect ULDM by looking for a distinctive feature in the central region of galactic rotation curves. Baryonic contributions to the gravitational potential pose an obstacle to such analyses, being (i) dynamically important in the inner galaxy and (ii) highly non-spherical in rotation-supported galaxies, resulting in non-spherical solitons. We present an algorithm for finding the ground state soliton solution in the presence of stationary non-spherical background baryonic mass distribution. We quantify the impact of baryons on the predicted ULDM soliton in the Milky Way and in low surface-brightness galaxies from the SPARC database.

description: The zeta and eta-functions associated with massless and massive Dirac operators, in a D-dimensional (D odd or even) manifold without boundary, are rigorously constructed. Several mathematical subtleties involved in this process are stressed, as the intrisic ambiguity present in the definition of the associated fermion functional determinant in the massless case and, also, the unavoidable presence (in some situations) of a multiplicative anomaly, that can be conveniently expressed in terms of the noncommutative residue. The ambiguity is here seen to disappear in the massive case, giving rise to a phase of the Dirac determinant - that agrees with very recent calculations appeared in the mathematical literature - and to a multiplicative anomaly - also in agreement with other calculations, in the coinciding situations. After explicit, nontrivial resummation of the mass series expansions involving zeta and eta functions, the results are expressed in terms of quite simple formulas.

description: We address quantum decision theory as a convenient framework to analyze process discrimination and estimation in qubit systems. In particular we discuss the following problems: i) how to discriminate whether or not a given unitary perturbation has been applied to a qubit system; ii) how to determine the amplitude of the minimum detectable perturbation. In order to solve the first problem, we exploit the so-called Bayes strategy, and look for the optimal measurement to discriminate, with minimum error probability, whether or not the unitary transformation has been applied to a given signal. Concerning the second problem, the strategy of Neyman and Pearson is used to determine the ultimate bound posed by quantum mechanics to the minimum detectable amplitude of the qubit transformation. We consider both pure and mixed initial preparations of the qubit, and solve the corresponding binary decision problems. We also analyze the use of entangled qubits in the estimation protocol and found that entanglement, in general, improves stability rather than precision. Finally, we take into account the possible occurrence of different kinds of background noise and evaluate the corresponding effects on the discrimination strategies.

description: PRISTIMANTIS TRACHYBLEPHARIS SPECIES GROUP
 Definition: The Pristimantis trachyblepharis species group is strongly supported in our phylogeny. Members of this group share the following morphological traits: (1) tympanic membrane present (except for P. minimus) and tympanic annulus distinct; (2) cranial crests absent; (3) dentigerous processes of vomer usually present; (4) males without vocal slits (except for P. minimus) and nuptial pads; (5) dorsal skin smooth to weakly tuberculate; (6) scapular folds distinct (except for P. minimus); (7) discs of fingers and toes narrowly expanded to expanded; (8) Finger I shorter than Finger II; (9) toes with narrow lateral fringes (except for P. minimus); (10) Toe V slightly longer to longer than Toe III; and (11) small size (SVL range in adult females from 14.08 to 23.76 mm, in adult males 11.04 to 16.80 mm).
 Content: The Pristimantis trachyblepharis species group comprises eight described species (four of them are described below): P. albujai Brito et al., 2017, P. aquilonaris Lehr et al., 2007, P. minimus Terán-Valdez & Guayasamin, 2010, P. nanus, P. pramukae, P. trachyblepharis (Boulenger, 1918), P. ujucami and P. ventristellatus.
 Distribution (Figs 3, 4): Eastern Andean slopes of central and southern Ecuador, and northern Peru, in five provinces: Morona Santiago, Pastaza, Tungurahua and Zamora Chinchipe in Ecuador and Huancabamba (Piura Department) in Peru. Species inhabit Eastern Montane Forest and Eastern Foothill Forest (Ron et al., 2019), between 981 and 2567 m a.s.l. They are found on low vegetation from the ground up to a height of 300 cm in forested areas with low vegetation.
 Remarks: According to our phylogeny, the P. trachyblepharis species group is strongly supported as sister to a clade composed of 18 species (Supporting Information, Figs S3, S 4) that have been included in several different groups (e.g. P. chalceus group, P. myersi group and P. unistrigatus group) or have not been assigned to any group (Hedges et al., 2008; Padial et al., 2014).

description: Purpose: Signaled by the completion of the Human Genome Project in 2003, rapid and escalating discovery in genome science has initiated a paradigm shift in education training and healthcare practices. This shift has required healthcare educators and professionals to possess a level of genetic and genomic literacy and competency. The current study was designed to survey the current state of the perceptions of genetics and genomics in educational and clinical practices within the field speech-language pathology. Method: Seventy-five program directors of degree programs and 265 speech-language pathologists participated in two web-based surveys. Results: Program directors and speech-language pathologist reported to be aware of recent genetic and genomic advancements in speech-language pathology. Ninety-six percent of program directors expected graduated students to demonstrate competency in genetic and genomic related clinical services. Thirty-six percent of program directors reported graduated students were prepared to understand genetics. Seventy-three percent of speech-language pathology programs offered genetic content in their curricula. In comparison, eighty-three percent of speech-language pathologists reported performing genetic related services within their clinical practices. Less than half of respondents reported confidence in performing clinical services. Speech-language pathologists reported minimal to no knowledge of at least 85% of genetic or genomic principles related to speech-language pathology. Sixty-three percent of speech-language pathologists reported their degree-training program had not prepared them to understand genomics in speech-language pathology. Results of a needs index revealed discrepancies between perceptions of speech-language pathologist's performed clinical services and program director's expected competencies, and between level of perceived preparedness and perceived knowledge. Thematic analysis across perceptions, course content, expected competencies, clinical services, and areas of knowledge reflected principles of Mendelian inheritance and single gene disorders. This "medical genetics" perspective is one typically used prior to the completion of Human Genome Project in 2003. Conclusion: The results of this investigative study suggest the field of communication sciences and its disorders is not keeping pace with the demands of new advancements in genetics and genomics. Several discrepancies may contribute to misconceptions and misinformation surrounding genetics and genomic in speech-language pathology. This study provides a foundation for discussion of curriculum reform at the graduate level and policy changes in standard practices of speech-language pathologists at the national level.

description: Strong gravitational lensing from black holes results in the formation of relativistic images, in particular, relativistic Einstein rings. For objects with event horizons, the radius of the unstable light ring (photon sphere) is the lowest radius at which a relativistic image might be formed. For horizonless ultracompact objects, additional relativistic images and rings can form inside this radius. In this paper, we provide an analytical approach to deal with strong gravitational lensing from such ultracompact objects, which is substantially different from the black hole cases, first reported by Bozza. Here, our analysis indicates that the angular separations and magnifications of relativistic images inside the unstable light ring (photon sphere) might be several orders of magnitude higher compared to the ones outside it. This indicates fundamental differences in the nature of strong gravitational lensing from black holes and ultracompact objects.

description: The Green Chemistry Initiative (GCI) is a student-led group founded in 2012 with the primary mission of promoting green chemistry education at the University of Toronto. In order to achieve this, the GCI’s activities have included undergraduate curriculum development, arrangement of an external speaker seminar series, and organization of an annual three-day symposium along with biweekly trivia challenges. To broaden education beyond the Department of Chemistry, a successful YouTube video campaign articulating the Twelve Principles of Green Chemistry in an accessible manner has also been undertaken (acquiring over 40,000 views), in addition to monthly blog posts and conference/outreach presentations. Descriptions of these activities are discussed in this paper, along with the resulting impact they have had. Through such efforts, undergraduate and graduate students are showing a growing understanding of the relevance of green chemistry in today’s world, with the GCI serving as a platform for similar groups to build upon across Canada.
Negative Modes in Vacuum Decay

description: A vacuum, a classically stable state, can decay to another vacuum by virtue of quantum tunneling. Although vacuum decay is an interesting topic itself in field theory, when it combines with gravity, it has wider applications and plays an essential role to understand the very early universe. The semi-classical solution of vacuum decay is well-described by the WKB approximation both in flat space and in curved space. Meanwhile, if we consider the configuration space of fields, we encounter many kinds of problems related with gravitational fields since the mode spectrum in curved space turns out to have an infinite number of negative modes in a de Sitter background. Despite of infinitely many negative modes, the regime in the weak gravity limit can be smoothly connected to flat space. To understand this, I discuss the nature of vacuum decay and various topics about negative modes in this thesis.

Assuming U-spin symmetry (i.e., $d \leftrightarrow s$ interchange symmetry) for the strong-interaction parts of these two channels, we find that their corresponding direct CP-violating asymmetries are ${\cal A}^{}_{\rm CP} (K^+ K^-) \simeq \left(-7.7 \pm 1.5\right) \times 10^{-4}$ and ${\cal A}^{}_{\rm CP} (π^+ π^-) \simeq \left(7.7 \pm 1.5\right) \times 10^{-4}$. The CP-forbidden transition $e^+ e^- \to D^0\bar{D}^0 \to \left(K^+ K^-\right)^{}_D \left(π^+ π^-\right)^{}_D$ on the $ψ(3770)$ resonance is therefore expected to have a rate of ${\cal O}(10^{-10})$ or smaller under U-spin symmetry, and it can be observed at a high-luminosity super-$τ$-charm factory if at least $10^{10}$ pairs of coherent $D^0$ and $\bar{D}^0$ events are accumulated.

description: In this paper we present three new extrasolar planets from the Qatar Exoplanet Survey (QES). Qatar-8b is a hot Saturn, with Mpl = 0.37 Mjup and Rpl = 1.3 Rjup, orbiting a solar-like star every Porb = 3.7 days. Qatar-9b is a hot Jupiter with a mass of Mpl = 1.2 Mjup and a radius of Rpl = 1 Rjup, in a Porb = 1.5 days orbit around a low mass, Mstar = 0.7 Msun, mid-K main-sequence star. Finally, Qatar-10b is a hot, Teq ~ 2000 K, sub-Jupiter mass planet, Mpl = 0.7 Mjup, with a radius of Rpl = 1.54 Rjup and an orbital period of Porb = 1.6 days, placing it on the edge of the sub-Jupiter desert.

Negotiated Openness: U.S.-Japan Financial Negotiations and the Network of Financial Officials

description: This study examines the role of intergovernmental negotiations in facilitating liberalization of finance in terms of market opening to foreign business. The theoretical focus is on the significance of the international network of financial officials. Recognized as a highly technical area, the financial issues have been often separated from other issue areas in trade negotiations, and administered by a small number of governmental financial experts. However, in reality, the exclusivity of financial officials on this issue largely resulted from their preexisting international network; these officials behaved strategically to maintain this exclusivity in such an institutional context. Yet, financial issues became politicized overtime and more actors, including politicians and governmental agencies other than financial authorities participated in the negotiations after the late 1980s.
           I argue that the structure of intergovernmental negotiations can have a significant impact on the outcomes of those negotiations. If negotiations are held exclusively among a small number of financial officials who share the understanding of the issues on the table and have long-term relationships with each other, the demands and offers in the negotiations tend to be more moderate and realistic, and the outcomes involve incremental changes. On the other hand, when the issues are politicized and more actors are involved, the demands tend to be tougher and the negotiations often break off.
           To assess this assertion, this study examines the United States-Japan financial negotiations, which were the world's first intergovernmental negotiations on financial liberalization, started in 1983. Initiated as bilateral negotiations, the financial negotiations were later incorporated into a multilateral framework, which changed the institutional settings. This study divides a series of bilateral negotiations into four periods. In the first period, the financial authorities started the bilateral negotiation. The second period followed in the late 1980s and the early 1990s, when the involvement of the American Congress had brought a considerable change in the nature and the outcome of the negotiation. In the third time period, the bilateral negotiations were held under the multilateral framework of the General Agreement on Tariffs and Trade (GATT). The case of financial services negotiations and that of insurance are compared in this period, as different sets of actors were involved in them.
           In conclusion, the study discusses the implications of the United States-Japan financial negotiations for the more recent developments in opening up the financial markets of newly industrialized economies.
Hard dilepton production from a weakly magnetized hot QCD medium

description: We have computed the hard dilepton production rate from a weakly magnetized deconfined QCD medium within one-loop photon self-energy by considering one hard and one thermomagnetic resummed quark propagator in the loop. In the presence of the magnetic field, the resummed propagator leads to four quasiparticle modes. The production of hard dileptons consists of rates when all four quasiquarks originating from the poles of the propagator individually annihilate with a hard quark coming from a bare propagator in the loop. Besides these, there are also contributions from a mixture of pole and Landau cut part. In weak field approximation, the magnetic field appears as a perturbative correction to the thermal contribution. Since the calculation is very involved, for a first effort as well as for simplicity, we obtained the rate up to first order in the magnetic field, i.e., ${\cal O}[(eB)]$, which causes a marginal improvement over that in the absence of magnetic field.

Negative regulation of gene expression by the tumor suppressor p53
Creators: Barsotti, Anthony M.
Publisher: name: Columbia University
Year: 2011
Subjects: Biology

description: The tumor suppressor p53 inhibits the expression of a substantial number of genes whose protein products serve to promote cell survival or cell cycle progression, thereby ensuring efficient execution of p53-dependent apoptosis, cell-cycle arrest or senescence. Furthermore, p53-mediated repression has also been shown to participate in pathways that regulate diverse cellular processes, including angiogenesis, maintenance of pluripotency, and metabolic flux. p53 inhibits gene expression by both direct and indirect means. Briefly, p53 can block transcription through direct DNA binding, association with transcription factors, and through the induction of genes whose functional products facilitate downstream repression. Indirect regulation of gene repression by p53 often involves induction of intermediary factors that fall into several categories: proteins (e.g. p21), microRNAs (e.g. miR-34a), and lincRNAs (lincRNA-p21). This dissertation discusses multiple aspects of p53-dependent gene repression and presents novel targets of p53-mediated regulation. Specifically, we have found that p53 down-regulates the transcription of the oncogenic transcription factor FoxM1. Mechanistically, this repression is largely dependent upon the p53-inducible gene p21, and consequently involves the Rb-family of tumor suppressors. Functionally, p53-dependent repression of FoxM1 contributes to the maintenance of a stable G2 cell cycle arrest in response to DNA-damage. In addition, we have identified PVT1 as a novel target of p53-transactivation. PVT1 encodes both spliced non-coding RNAs (ncRNA), as well as a series of microRNAs (miR-1204, miR-1205, miR-1206, miR-1207-5p, miR-1207-3p and miR-1208). p53 upregulates PVT1 ncRNA, primary microRNAs, and mature miR-1204. Ectopic expression of miR-1204 induces changes in cell fate that are consistent with the role of p53 (cell death, cell cycle arrest), thus miR-1204 is likely to represent a functional target of p53 at the PVT1 locus.
A Sussex Dissenting Family: The Ridges of Westgate Chapel, Lewes

description: Members of the widely extended Sussex family of Ridge were prominent in the affairs of the congregation of Westgate Chapel, Lewes from the late 17th century until the 1870s. This article examines the part the Ridges (as trustees and principal subscribers) played in the life of the chapel and the part that it (as meeting-house and social centre) played in theirs. Jn the belief that religious developments are best studied in their wider political, social and economic context some attempt is also made to find out how far the family's Nonconformist principles affected their everyday lives. Contrary to the popular view, which associates Nonconformity with urban trade and industry, most of the Ridges were farmers and a few were landlords rich enough to live off their rents. But they all lived unostentatiously. They seem to have exhibited the 'plain living and high thinking' characteristic of the old English Presbyterians. Some of them were well read in theology and philosophy, and one of them founded the first Lewes library. A number took an active part in public affairs, serving as constables, overseers of the poor, tax assessors and ( in one instance) as an inspector of militia. All members of the family who were worshipping at Westgate when Thomas Walker Horsfield was minister probably supported his liberal stance in political matters. Jn one way or another the Ridges made a significant contribution to the social and religious life of their locality over a period of two centuries.
Masses and decays of the bottom-charm hybrid meson $c \bar{b} g$

description: We study gluonic excitations inside a $B_{c} $ meson in the constituent gluon model, treating a bottom-charm hybrid meson $ c \bar{b} g $ as a three-body system. We obtain the mass spectra for the hybrid mesons with magnetic gluon and electric gluon and see that their lowest states appear above the $ D B $ threshold. Also, we consider the decays of the low-lying states of the hybrid meson into $ DB , \; D^{*} B, DB^{*} $, $ D^{*}B^{*} $, $ D_{s} B_{s} $, and $D_{s} B_{s}^{*} $ mesons, developing an existing model for the strong decays. We estimate their partial decay widths and find that the widths have a heavy dependence on the final meson states. We argue that the accuracy of our model will be tested experimentally when the branching ratios of the decays are measured. Our results suggest that there could be a prospect that the hybrid meson will be discovered as its first excited state rather than its lowest state.
