    The purpose of this article is to identify the key elements of market determinants of bond yield and the external borrowing environment. A reasonably integrated bond market is safer for both investors as well as issuers. It assesses the robustness of integration in corporate bond yields. Research method applied in this particular study includes the overview of theoretical concepts, literature review and analysis of secondary yield data. The results revealed significant differences between the sensitivity of coupon bonds and zero coupon bonds. It demonstrated stronger relationship between bond yield, money markets and external credit markets, respectively. Modern bond portfolios can be constructed focusing on factors beyond coupon rates, duration and credit rating, respectively. The outcome or further research could focus on examining alternate anchors against secured overnight short term financing rates

    Let GG be a graph with vertex set VV and of order n=∣V∣n = |V|, and let δ(G)\delta(G) and Δ(G)\Delta(G) be the minimum and maximum degree of GG, respectively. Two disjoint sets V1,V2⊆VV_1, V_2 \subseteq V form a coalition in GG if none of them is a dominating set of GG but their union V1∪V2V_1\cup V_2 is. A vertex partition Ψ={V1,…,Vk}\Psi=\{V_1,\ldots, V_k\} of VV is a coalition partition of GG if every set Vi∈ΨV_i\in \Psi is either a dominating set of GG with the cardinality ∣Vi∣=1|V_i|=1, or is not a dominating set but for some Vj∈ΨV_j\in \Psi, ViV_i and VjV_j form a coalition. The maximum cardinality of a coalition partition of GG is the coalition number C(G)\mathcal{C}(G) of GG. Given a coalition partition Ψ={V1,…,Vk}\Psi = \{V_1, \ldots, V_k\} of GG, a coalition graph \CG(G, \Psi) is associated on Ψ\Psi such that there is a one-to-one correspondence between its vertices and the members of Ψ\Psi, where two vertices of \CG(G, \Psi) are adjacent if and only if the corresponding sets form a coalition in GG. In this paper, we partially solve one of the open problems posed in Haynes et al. \cite{coal0} and we solve two open problems posed by Haynes et al. \cite{coal1}. We characterize all graphs GG with δ(G)≤1\delta(G) \le 1 and C(G)=n\mathcal{C}(G)=n, and we characterize all trees TT with C(T)=n−1\mathcal{C}(T)=n-1. We determine the number of coalition graphs that can be defined by all coalition partitions of a given path. Furthermore, we show that there is no universal coalition path, a path whose coalition partitions defines all possible coalition graphs

    Thermodynamics of the oxidation of ZrB2-TiB2, ZrB2-SiC and ZrB2-B4C ceramics

    The thermodynamics of the oxidation of three-high temperature ZrB2-based ceramics (ZrB2-TiB2, ZrB2-SiC and ZrB2-B4C) has been studied in order to find the stability domain of zirconium diboride, in terms of temperature, partial pressure of oxygen and composition, in which it is protected against oxidation. In the case of the ZrB2-TiB2 binary system, a plot of log pO2vs. 1/T in the temperature range of 500-2000 K and another plot of pO2 (x1014) vs.xTiB2 for T=2000 K are made taking into account the two-extreme possibilities of no solubility and 100% solid solubility between ZrB2 and TiB2, respectively. A plot of log pCOvs. log pO2 is made for 1773 K for the systems ZrB2-SiC and ZrB2-B4C. It was found that the ZrB2-TiB2 ceramics does not have sufficient oxidation resistance in the temperature range of 500-2000 K. ZrB2 of ZrB2-SiC ceramics can be protected under 1 atmosphere oxygen or in air if the liquid borosilicate (with the chosen composition, 70% B2O3-30% SiO2), which is an intermediate product, provides a kinetic barrier to the continuation of oxidation by forming an impervious layer on the exposed surfaces. In contrast, the ZrB2-B4C ceramics does not produce the borosilicate upon oxidation. In view of the volatility of pure liquid B2O3, it is recommended that the ZrB2-B4C ceramics can be used at a lower temperature, perhaps below 1373 K, when the vapour pressure of B2O3 is significantly small

    Protein evolution: intrinsic preferences in peptide bond formation: a computational and experimental analysis

    Get PDF
    Two possibilities exist for the evolution of individual enzymes/proteins from a milieu of amino acids, one based on preference and selectivity and the other on the basis of random events. Logic is overwhelmingly in favour of the former. By protein data base analysis and experiments, we have provided data to show the manifestation of two types of preferences, namely, the choice of the neighbour and its acceptance from the amino end (left) or the carboxyl end (right). The study tends to show that if the 20 proteinous amino acids were made to combine in water, the resulting profile would be nonrandom. Such selectivity could be a factor in protein evolution

    Cops and robber on subclasses of P5P_5-free graphs

    Full text link
    The game of cops and robber is a turn based vertex pursuit game played on a connected graph between a team of cops and a single robber. The cops and the robber move alternately along the edges of the graph. We say the team of cops win the game if a cop and the robber are at the same vertex of the graph. The minimum number of cops required to win in each component of a graph is called the cop number of the graph. Sivaraman [Discrete Math. 342(2019), pp. 2306-2307] conjectured that for every t≥5t\geq 5, the cop number of a connected PtP_t-free graph is at most t−3t-3, where PtP_t denotes a path on tt~vertices. Turcotte [Discrete Math. 345 (2022), pp. 112660] showed that the cop number of any 2K22K_2-free graph is at most 22, which was earlier conjectured by Sivaraman and Testa. Note that if a connected graph is 2K22K_2-free, then it is also P5P_5-free. Liu showed that the cop number of a connected (PtP_t, HH)-free graph is at most t−3t-3, where HH is a cycle of length at most tt or a claw. So the conjecture of Sivaraman is true for (P5P_5, HH)-free graphs, where HH is a cycle of length at most 55 or a claw. In this paper, we show that the cop number of a connected (P5,HP_5,H)-free graph is at most 22, where H∈{C4H\in \{C_4, C5C_5, diamond, paw, K4K_4, 2K1∪K22K_1\cup K_2, K3∪K1K_3\cup K_1, P3∪P1}P_3\cup P_1\}

    INFORMATION CONTENT OF STOCKS IN CALL AUCTION OF SHORTER DURATION IN EMERGING MARKET

    Pre-open auctions have been widely implemented across trading exchanges. Pre-open auctions tend to reduce information asymmetry and trading risks. Call auctions have been encouraged to enhance price discovery. This paper explores the shifts in information content of the pre-market auction session over time. We derive that the information content of the pre opening auction did improve little after a gap of two months. We conclude that the intraday 15 minutes realized volatility was influenced by information content in the pre-market. We demonstrate that volatility is the cause of order imbalance or a cause of poor information content. The investigation of the related volatility in the futures segment provides interesting insights on the unusual pre-market imbalances visualized on days close to expiry of futures

    An Augmented Taylor rule for India’s Monetary Policy: Does Governor Regime Matters?

    Get PDF
    This paper examined the monetary policy stance in India during the governors’ regime of Jalan- Reddy-Subbarao- Rajan. An Augmented Taylor Rule is employed to estimate monetary policy response for each period using monthly data. The results revealed that the governor regime matters in the monetary policy response. When output gap has been an important concern during Jalan, Subbarao and Rajan’s period, inflation remained a major concern for Reddy and Rajan’s regime. Interestingly, the interest rate is highly responsive to changes in exchange rate during Rajan period. These findings are consistent with the conditions of economy during those periods. In addition, the exchange rate and output gap remained a greater concern for policy maker in post-crisis period. Nevertheless, we find policy inertia during all regimes

    The crafting of uracils with enhanced stacking potential

    Get PDF
    Uracils having enhanced stacking profile are of interest from diverse vantages ranging from the chemical simulation of transcription to the design of novel anti viral agents. This objective has been realized by synthetic strategies leading to uracils having,inter alia, pseudo aromatic and hydrophobic rings crafted to the 5-6 location and ionophore and hydrophobic chains affixed at the C-5 and nitrogen atoms. Endeavours to prepare a 5-2' uracil-pyrimidine composite have led to novel uracil arising from 2-O → =CH(COOR)2 transformation and a tethered malonic acid pyrimidine complex
