  • This study examines the relationship between bank efficiency and earnings management (EM) using a large sample of banks from 22 frontier market countries from 2011 - 2018, We hypothesise that EM via loan loss provision (LLP) and loan loss reserves (LLR) adversely impacts bank efficiency. Employing stochastic frontier analysis as a technical efficiency measurement, and random effects and truncated regression to reveal their relationship, we find support for this prediction. Also, in three of the five geographic regions tested, efficiency scores are higher for larger banks.

  • Single-molecule RNA fluorescence in situ hybridization (smFISH) provides unparalleled resolution in the measurement of the abundance and localization of nascent and mature RNA transcripts in fixed, single cells. We developed a computational pipeline (BayFish) to infer the kinetic parameters of gene expression from smFISH data at multiple time points after gene induction.

  • Allele-specific expression is traditionally studied by bulk RNA sequencing, which measures average expression across cells. Single-cell RNA sequencing allows the comparison of expression distribution between the two alleles of a diploid organism and the characterization of allele-specific bursting.

  • This measure, developed for evaluating customer churn uplift models, extends the maximum profit measure for evaluating customer churn prediction models. While introducing the MPU measure, we describe the generally applicable liftup curve and liftup measure for evaluating uplift models as counterparts of the lift curve and lift measure that are broadly used to evaluate predictive models.

  • Electrochemical noise measurements have been applied to electrochemical systems that show stochastic behavior. The standard area of study that benefits from this stochastic analysis is localized corrosion modes like pitting and crevice corrosion. Application of electrochemical noise measurements to battery systems, though rare, is recently becoming more popular. The present contribution first establishes a method of analyzing electrochemical voltage noise data for NiCd batteries, then follows four samples of batteries in terms of voltage noise throughout their lifetimes.

  • This study applies a combination of DEA (Data Envelopment Analysis) model and the SFA (Stochastic Frontier Analysis) model to measure the impacts of M&A activities on the banking efficiency in Vietnam from 2011 to 2018. The results show that merge and acquisition (M&A) activities had a positive effect that reflects in an increase of the index of banking efficiency from 2011 to 2013.

  • The paper aims to enrich previous findings for an emerging banking industry such as Vietnam, reporting the difference between the parametric and nonparametric methods when measuring cost efficiency. The purpose of the study is to assess the consistency in issuing policies to improve the cost efficiency of Vietnamese commercial banks.

  • Interest in understanding the mechanisms that lead to a particular composition of the Gut Microbiota is highly increasing, due to the relationship between this ecosystem and the host health state. Particularly relevant is the study of the Relative Species Abundance (RSA) distribution, that is a component of biodiversity and measures the number of species having a given number of individuals.

  • The Stochastic Process Model (SPM) represents a general framework for modeling the joint evolution of repeatedly measured variables and time-to-event outcomes observed in longitudinal studies, i.e., SPM relates the stochastic dynamics of variables (e.g., physiological or biological measures) with the probabilities of end points (e.g., death or system failure).

  • The Partially-Observed Boolean Dynamical System (POBDS) signal model is distinct from other deterministic and stochastic Boolean network models in removing the requirement of a directly observable Boolean state vector and allowing uncertainty in the measurement process, addressing the scenario encountered in practice in transcriptomic analysis.

  • Cells operate in an uncertain environment, where critical cell decisions must be enacted in the presence of biochemical noise. Information theory can measure the extent to which such noise perturbs normal cellular function, in which cells must perceive environmental cues and relay signals accurately to make timely and informed decisions.

  • This paper extends the work of Chen and Chang (2010) and attempts to present a model for the optimal investment threshold and the real option value under price uncertainty from a different aspect of entry probability. I measure a financing policy by the debt ratio, a weight for the proportion of funding by debt relative to funding by equity. The weight is exogenously embedded in the stochastic optimization of an investment opportunity under price uncertainty. An entry probability, indicating the likelihood of an investment action optimally taken at a future time instant, is derived.

  • This paper measures the cost inefficiency of Vietnamese commercial banks from 2011 to 2014. Stochastic frontier analysis (SFA) is used to estimate the cost frontier. The average cost inefficiency of the whole banking system is 7.36% under intermediation approach. Findings show that state-owned banks and banks with bigger size are more efficient than joint stock or smaller ones. Negative relationships are found between efficiency and deposit-to-loan ratio as well as bank‟s age.

  • Total and lobar depositions of fungal particles in the human lung were calculated for the workers in a cotton spin factory using an updated version of the Monte Carlo transport and deposition code IDEAL. The study is based on nasal breathing under light exercises activity with a standard functional residual capacity (FRC) of 3300 ml, tidal volume (VT) of 1250 ml and breathing frequency (f) of 20 min1 . The present calculation is based on our previous measurements of the size distribution of fungal particles in the cotton spin factory using six-stage Andersen impactor as a viable sampler.

  • For a given finite positive measure on an interval I ⊆ R, a multiple stochastic integral of a Volterra kernel with respect to a product of a corresponding Gaussian orthogonal stochastic measure is introduced. The Volterra kernel is taken such that the multiple stochastic integral is a multiple iterated stochastic integral related to a parameterized Hermite polynomial, where parameter depends on Gaussian distribution of an underlying one-dimensional stochastic integral.
