IFRSs for financial instruments, quality of information and capital market’s volatility: an empirical assessment for Eurozone

This study examines the Eurozone stock markets’ reaction to a number of events associated with the post-implementation amendments of the IFRSs regarding financial instruments (IFRS 7, IFRS 9, IAS 32 and IAS 39). The adoption of these IFRSs is probably one of the most important recent changes in financial information environment. However, in order to contribute to an increase in financial stability, it is necessary to ensure an ex post stability of the regulatory framework. Based on this meta-argument, we have analyzed the inter-linkages between the episodes of higher market volatility and the amendments to the mentioned IFRSs, inside a binary dependent variable model. Overall, our findings suggest that the adoption of the IFRS can lead to a stabilization of European financial markets but this result is not necessary a robust one since investors prefer a higher stability on standards’ contents and application conditions.
Early Afterdepolarizations with Growing Amplitudes via Delayed Subcritical Hopf Bifurcations and Unstable Manifolds of Saddle Foci in Cardiac Action Potential Dynamics

Early afterdepolarizations (EADs) are pathological oscillations in cardiac action potentials during the repolarization phase and may be caused by drug side effects, ion channel disease or oxidative stress. The most widely observed EAD pattern is characterized by oscillations with growing amplitudes. So far, its occurence has been explained in terms of a supercritical Hopf bifurcation in the fast subsystem of the action potential dynamics from which stable limit cycles with growing amplitudes emerge. The novel contribution of this article is the introduction of two alternative explanations of EAD genesis with growing amplitudes that do not involve stable limit cycles in fast subsystems. In particular, we demonstrate that EAD patterns with growing amplitudes may alternatively arise due to a delayed subcritical Hopf bifurcation or an unstable manifold of a saddle focus fixed point in the full fast-slow system modelling the action potential. Our work extends the list of possible dynamical EAD mechanisms and may contribute to a classification of drug effects in preclinical cardiotoxicity testing.
Efficacy of Intense Pulsed Light Therapy in the Treatment of Facial Acne Vulgaris: Comparison of Two Different Fluences

Background: Acne vulgaris is the most common disease of the skin affecting adolescents and young adults causing psychological distress. The combination of antibiotic resistance, adverse effects of topical and systemic anti acne medications and desire for high tech approaches have all led to new enthusiasm for light based acne treatment. Intense pulse light (IPL) therapy has three modes of action in acne vulgaris i.e., photochemical, photo thermal and photo immunological. Aims: (1) to study efficacy of IPL therapy in facial acne vulgaris. (2) To compare two fluences - one normal and other subnormal on right and left side of face respectively. Methods: (Including settings and design and statistical analysis used). Total 45 patients in age group 16 to 28 years with inflammatory facial acne vulgaris were included in prospective study. Baseline data for each patient was recorded. All patients were given 4 sittings of IPL at 2 weeks interval and were followed for 2 months every 2 weeks. Fluence used was 35J/cm2 on right and 20J/cm2 on left side. Percentage reduction in lesion count was calculated at each sitting and follow up and graded as mild (0-25%), moderate (26-50%), good (51-75%) and excellent (76-100%). Side effects were noted. The results were analysed using Mann-Whitney Test. Results: On right side, excellent results were achieved in 10(22%), good in 22(49%) and moderate in 13(29%) patients. On left side excellent were results achieved in 7(15%), good in 19(42%) and moderate in 16(43%) patients. There was no statically significant difference noted in efficacy of two fluences used in treatment of facial acne vulgaris. Conclusions: IPL is a effective and safe option for inflammatory acne vulgaris with minimal reversible side effects. Subnormal fluence is as effective as normal fluence in Indian skin.

Novel Adaptive Control and State-Feedback Control Strategies to Finite-Time Stabilization of Discontinuous Delayed Networks

This paper is concerned with the finite-time stabilization problem for a class of delayed neural networks (DNNs) with discontinuous neuron activations. In order to stabilize the states of such DNNs in finite time, we design two classes of novel control strategies including switching adaptive control strategy and switching state-feedback control strategy. Based on the theory of differential inclusions, the famous finite-time stability theorem and the generalized Lyapunov functional method, several sufficient conditions are established to ensure the finite-time stabilization control of discontinuous DNNs. In addition, we also provide the settling time for stabilization which has an important significance in the application of neural networks for guaranteeing fast response. Finally, numerical examples are given to demonstrate the effectiveness of the proposed control strategies and main results.
Retrieval of Vertical Rain Rate Profile by Dual-Frequency Radar Data

Based on the success of the TRMM mission, GPM (Global Precipitation Measurement) mission was proposed. A dual-frequency precipitation radar (DPR) on the core satellite of GPM is expected to play a significant role in the mission (Iguchi, 2003). Testud (2004) described that there were two approaches, that is, “differential” (Iguchi and Meneghini 1995) and “integral” (Meneghini and Nakamura 1990) techniques in dual-frequency algorithm for the retrieval of rain rate profile. In this study, retrieval algorithm of vertical rain rate profile by dual-frequency radar was proposed in line with integral approach and applied to the NIED ground-based radar data.
Does Expectations Management Impair the Usefulness of Analyst Forecasts in Firm Valuation?

In this paper, I examine how expectations management for the purpose of meeting or beating analyst expectations (MBE) impairs the ability of analyst forecast-based valuation models to predict firms' intrinsic values. I predict that management's manipulation of analyst expectations introduces error in analyst forecasts and reduces their ability to proxy future expected earnings; consequently, valuation models estimated using these manipulated forecasts have less ability than those estimated using non-manipulated forecasts to predict firms' true intrinsic values. The results show that, consistent with my prediction, intrinsic value metrics estimated using manipulated forecasts have less ability to track stock price (as evidenced by their lower correlation with stock prices and less stationary V/P time-series) and to predict future returns. These results provide consistent evidence for the negative impact of expectations management on the ability of accounting valuation models to predict firm value. This study contributes to the literature in two major respects: (i) it introduces an improved measure of expectations management to MBE; and (ii) it proposes expectations management (forecast manipulation) as a new determinant of the ability of accounting valuation models to predict firm value.
Large Cell Neuroendocrine Carcinoma of the Nasopharynx: A Pediatric Case

Neuroendocrine tumors are rare, preferentially located in the gastrointestinal tract or in the lungs. We present the case of a 9-year-old child, presenting with a tissue mass involving the nasopharynx and associated with multiple pulmonary and bone metastases. The immunohistochemical analysis showed a proliferation of large tumor cells stained with Chromogranin A and Synaptophysin. The diagnosis of multimetastatic large cell neuroendocrine carcinoma was made. This tumor is infrequent in this location and particularly in children. This case describes the pathologic aspects and immunohistochemical results and presents a discussion of the differential diagnoses.
Glucose Uptake Kinetics and Transcription of HXTGenes in Chemostat Cultures of Saccharomyces cerevisiae *

The kinetics of glucose transport and the transcription of all 20 members of the HXT hexose transporter gene family were studied in relation to the steady statein situ carbon metabolism of Saccharomyces cerevisiae CEN.PK113-7D grown in chemostat cultures. Cells were cultivated at a dilution rate of 0.10 h−1 under various nutrient-limited conditions (anaerobically glucose- or nitrogen-limited or aerobically glucose-, galactose-, fructose-, ethanol-, or nitrogen-limited), or at dilution rates ranging between 0.05 and 0.38 h−1 in aerobic glucose-limited cultures. Transcription ofHXT1–HXT7 was correlated with the extracellular glucose concentration in the cultures. Transcription of GAL2, encoding the galactose transporter, was only detected in galactose-limited cultures. SNF3 and RGT2, two members of the HXT family that encode glucose sensors, were transcribed at low levels. HXT8–HXT17 transcripts were detected at very low levels. A consistent relationship was observed between the expression of individual HXT genes and the glucose transport kinetics determined from zero-transinflux of 14C-glucose during 5 s. This relationship was in broad agreement with the transport kinetics of Hxt1–Hxt7 and Gal2 deduced in previous studies on single-HXT strains. At lower dilution rates the glucose transport capacity estimated from zero-trans influx experiments and the residual glucose concentration exceeded the measured in situ glucose consumption rate. At high dilution rates, however, the estimated glucose transport capacity was too low to account for the in situ glucose consumption rate.
Governance and Intermediation Problems in Capital Markets: Evidence from the Fall of Enron

The financial reporting and disclosure problems at Enron, as well as the high market valuations for its stock raise troubling questions about the performance of capital market intermediaries, regulators and governance experts whose are supposed to ensure the effective functioning of the stock market. This paper examines the functions of key capital market intermediaries and analyzes how their own governance and incentive problems may have contributed to Enron's rise and fall. We conclude by proposing system modifications to resolve the observed problems.
Physiological Behaviour and Yield Performances of Hybrid Rice at Different Planting Dates in Aus Season

Two field experiments were conducted in 2009 and 2010 to evaluate some physiological traits and yield of three hybrid rice varieties (BRRI hybrid dhan2, Heera2, and Tia) in comparison to BRRI dhan48 in Aus season. The experiments involved four planting dates (1 April, 16 April, 1 May and 16 May). Compared to BRRI dhan48, hybrid varieties accumulated greater shoot dry matter at anthesis, higher flag leaf chlorophyll at 2, 9, 16 and 23 days after flowering (DAF), flag leaf photosynthetic rate at 2 DAF and longer panicles. However, hybrid varieties demonstrated smaller remobilization of shoot reserve to grain and photosynthetic rate of its flag leaf at 9 and 16 DAF than BRRI dhan48. Heera2 and BRRI hybrid dhan2 maintained significantly higher chlorophyll a:b ratio over Tia and BRRI dhan48 at 2, 9, 16 and 23 DAF in their flag leaf. Shoot reserve remobilization to grain exhibited higher degree of sensitivity to rising of minimum temperature in the studied hybrids compared to the inbred. Inefficient photosynthetic activities of flag leaf and poor shoot reserve translocation to grain resulted poor grain filling percentage in the test hybrids. Consequently the studied hybrids showed significantly lower grain yield ( ca . 36.7%) as compared to inbred BRRI dhan48, irrespective of planting date in Aus season.

ON MULTIDIMENSIONAL

We study the approximability of multidimensional generalizations of three classical packing problems: multiprocessor scheduling, bin packing, and the knapsack problem. Speciﬁcally, we study the vector scheduling problem, its dual problem, namely, the vector bin packing problem, and a class of packing integer programs . The vector scheduling problem is to schedule n d -dimensional tasks on m machines such that the maximum load over all dimensions and all machines is minimized. The vector bin packing problem, on the other hand, seeks to minimize the number of bins needed to schedule all n tasks such that the maximum load on any dimension across all bins is bounded by a ﬁxed quantity, say, 1. Such problems naturally arise when scheduling tasks that have multiple resource requirements. Finally, packing integer programs capture a core problem that directly relates to both vector scheduling and vector bin packing, namely, the problem of packing a maximum number of vectors in a single bin of unit height. We obtain a variety of new algorithmic as well as inapproximability results for these three problems.
Commercial and Investment Banks – United or Divided?

The concept of separation of commercial and investment banking has been the subject of debate since the great depression of the 1930’s. The US Congress saw the need to separate the two activities through the enactment of the Glass-Steagall Act of 1933. This argument resurfaced after the subprime crisis of 2007-2008 has resulted in the loss of approximately $1.1 trillion, with a dozen and a half large universal banks responsible for half of the losses (Wilmarth Jr, 2009). The global financial meltdown was subverted through the efforts of governments and central banks which subscribed $9 trillion for the support of institutions. The underpinning factor of this crisis was the amount of risk undertaken by too large to fail institutions with funds belonging to individuals (Blundell-Wignall, Atkinson and Roulet, 2014). The argument for the split-up of commercial and investment banking is not clear cut, however the most prominent argument suggest that the separation is necessary to ensure the separation of and protection of customer pledges from market risks (de Larosiere, 2012) ensuring that taxpayer funds are not used to avert risky investments.
Automatic construction of lexicons, taxonomies, ontologies, and other knowledge structures

Abstract, structured, representations of knowledge such as lexicons, taxonomies, and ontologies have proven to be powerful resources not only for the systematization of knowledge in general, but to support practical technologies of document organization, information retrieval, natural language understanding, and question‐answering systems. These resources are extremely time consuming for people to create and maintain, yet demand for them is growing, particularly in specialized areas ranging from legacy documents of large enterprises to rapidly changing domains such as current affairs and celebrity news. Consequently, researchers are investigating methods of creating such structures automatically from document collections, calling on the proliferation of interlinked resources already available on the web for background knowledge and general information about the world. This review surveys what is possible, and also outlines current research directions.
Preservation of Human Cornea

The successful outcome of the majority of corneal transplants depends on the presence of a viable corneal endothelium. This monolayer of cells lines the inner surface of the cornea and its primary function is to maintain corneal transparency by controlling the hydration of the collagenous stromal layer. Since human corneal endothelial cells do not readily proliferate, preservation of the endothelium is a primary aim of methods of corneal storage. Although some cryopreserved corneas have been transplanted successfully, the complexity of the cryopreservation technique and its potential for causing endothelial damage have limited its application. Hypothermia (2–8°C) is the most commonly applied method of storage, which allows storage for 7–14 days. Organ culture (28–37°C), which extends storage time to 4 weeks, is used widely in European eye banks. Graft outcomes for corneas stored by these two techniques appear similar.
Drying: An Excellent Method for Food Preservation

Drying is an ancient technique of food preservation & for extension of shelf-life of foods; and it also minimizes the transportation cost as well as the storage cost per unit product weight. Sun drying is the most common method to preserve the foods in rural area whereas in industries mechanical drying is in practice. Preservation of fruits and vegetables, meat, fish and food plants by drying in the sun or in the naturally dry air of the deserts and mountains has been practiced and is still a vital operation in the life of many rural communities. For the faster drying (i.e. time saving) and more versatility in commercial scale mechanical drying is the common technique to preserve the food stuffs.
Time‐related effects of estrogen withdrawal on proliferation‐ and cell death‐related events in MCF‐7 xenografts

Endocrine treatments for human breast cancer have been based largely upon the removal of estrogenic stimuli. The regression of tumors after estrogen deprivation has generally been characterized as being due to reduced proliferation but more recently has been recognized to also involve increased apoptosis. The aim of our experiments was to define the associated changes in certain proliferation‐ and cell death‐related biological parameters after hormone withdrawal from estrogen‐dependent MCF‐7 xenografts in athymic nude mice using immunohistochemical techniques. The baseline estrogen receptor (ER) level of this MCF‐7 xenograft was relatively low (average H score 23) but it was strongly Bcl‐2‐, PgR‐ and pS2‐positive, indicating the functional integrity of estrogen signaling. Changes in proliferation (Ki‐67), apoptosis, ER, progesterone receptor (PgR), cyclin D1, p27kip1, Bcl‐2 and Bax expression were assessed during the 2 weeks after estrogen deprivation. ER levels rose markedly after estrogen ablation, whereas PgR levels fell to about 10% of baseline and pS2 levels halved. The proportion of Ki‐67‐positive cells was unchanged after 24 hr but by day 14 had reduced by about 80%. The normal levels of cyclin D1 also reduced after estrogen withdrawal in contrast to the rapid increase in levels of cyclin‐dependent kinase inhibitor p27kip1. This latter increase appeared to occur in advance of the changes in Ki‐67. The proportion of apoptotic cells increased from a mean 1.5% at baseline to 2.9% after 3 days and 4.7% after 14 days. There were reductions in both Bcl‐2 and Bax staining but these appeared to be greater for Bcl‐2, effectively decreasing the Bcl‐2/Bax ratio. Our results provide a framework for the use of these parameters as intermediate markers in comparisons of hormonal agents for human breast cancer treatment. Int. J.

Information technology and the inferential gap.

In medical practice, an "inferential gap" exists in two contexts: the nonapplication of relevant existing evidence, and the absence of evidence germane to a particular clinical situation. Randomized controlled trials are the current gold standard of evidence development; however, they suffer limits of generalization to the "real world. " Conversely, observational studies might be more generalizable but are prone to bias, data inconsistency, and measurement error. The electronic health record offers hope for supporting the real-time presentation of information relevant to a clinical situation and serves as a platform for the conduct of large observational studies and novel quasi-experimental research.
Resource Allocation for Virtualized Wireless Networks with Backhaul Constraints

In this letter, we study resource allocation for wireless virtualized networks considering both the backhaul capacity of the infrastructure provider (InP) and the users’ quality-of-service (QoS) requirements. We focus on the profit gained by a mobile virtual network operator (MVNO), which is a middleman who buys physical resource from the InP, bundling them into virtual resources called slides before selling off the service providers. The objective of the MVNO is to maximize its profit while guaranteeing the backhaul constraint and users’ QoS by jointly allocating the slices and the uplink transmit power to the users. To solve the formulated mixed integer non-convex problem, we propose a distributed solution framework based on Lagrangian relaxation to a find suboptimal decision about slice and transmit power allocations. We further propose a low-complexity solution based on the concept of a matching game that does not require any global information. Numerical results are provided to evaluate the performance of the proposed schemes.
