Second Generation of 'Miranda Procedure' for CP Violation in Dalitz Studies of B (\& D \& \tau) Decays

The `Miranda Procedure' proposed for analyzing Dalitz plots for CP asymmetries in charged B and D decays in a model-independent manner is extended and refined. The complexity of CKM CP phenomenology through order $\lambda^6$ is needed in searches for New Dynamics (ND). Detailed analyses of three-body final states other great advantages: (i) They give us more powerful tools for deciding whether an observed CP asymmetry rep- resents the manifestation of ND and its features. (ii) Many advantages can already be obtained by the `Miranda Procedure' without construction of a detailed Dalitz plot de- scription. (iii) One studies CP asymmetries independent of production asymmetries. We illustrate the power of a second generation Miranda Procedure with examples with time integrated rates for $B_d/\bar B_d$ decays to final states $K_S\pi+\pi-$ as trial runs with comments on $B^{\pm} \to K^{\pm}\pi^+\pi^-/K^{\pm}K^+K^-$.Comment: 29 pages, 7 figure

Are provisions and contingent liabilities priced by the market? An exploratory study in Portugal and the United Kingdom

Purpose: This paper aims to examine pricing differences regarding contingencies presented in statements of financial position or notes, which are considered an area for creative accounting. Design/methodology/approach: The authors have chosen two countries with different cultural environments to test the exploratory study. The sample includes companies using the International Accounting Standard (IAS) 37, which requires recognition of provisions while contingent liabilities are only disclosed, implying different impacts from underlying judgement related with contingencies. The authors apply a regression model based on the Ohlson equity-valuation framework. Findings: The most important conclusion is that market participants in both countries follow different patterns when incorporating information about provisions and contingent liabilities. More precisely, the results suggest that provisions are value-relevant, but incrementally less negative in Portugal. Contingent liabilities seem to have no value relevance. However, an exception exists for Portuguese companies having a risk committee board, in which case a significant market valuation of contingent liabilities is found and discounted in share prices. The existence of a risk committee corroborates the value relevance of this board, which is positively valued by market participants in both national cultures. Practical implications: The findings may make a contribution to the IASB research project on the IAS 37 and possible amendments to it (suspended until the revisions to the conceptual framework are finalized) and to the IASB prioritization of communication effectiveness of financial statements to all users. Originality/value: Value relevance of contingencies differentiating countries from two different national cultures and firms with a risk committee on the board of directors.info:eu-repo/semantics/acceptedVersio

Carotid Artery Dissection

A dissecção da artéria carótida interna é uma causa de AVC isquémico, particularmente em doentes jovens, sem aparentes factores de risco cérebro-vasculares. Métodos: Os autores descrevem o quadro clínico e achados imagiológicos (TAC, RMN e angiografia de subtracção digital) de cinco doentes internados consecutivamente na Unidade Cérebro-Vascular do Hospital de S. José, num período de dois meses, com o diagnóstico de oclusão da artéria carótida interna por provável dissecção. Discussão: O conjunto de casos clínicos apresentados salienta a heterogeneidade de formas de apresentação desta patologia, quer do ponto de vista clínico, quer imagiológico

Entanglement and Bell's inequality violation above room temperature in metal carboxylates

In the present work we show that a special family of materials, the metal carboxylates, may have entangled states up to very high temperatures. From magnetic susceptibility measurements, we have estimated the critical temperature below which entanglement exists in the cooper carboxylate \{Cu$_2$(O$_2$CH)$_4$\}\{Cu(O$_2$CH)$_2$(2-methylpyridine)$_2$\}, and we have found this to be above room temperature ($T_e \sim 630$ K). Furthermore, the results show that the system remains maximally entangled until close to $\sim 100$ K and the Bell's inequality is violated up to nearly room temperature ($\sim 290$ K)
