In this paper the kurtosis of the logistic-exponential distribution is analyzed. All the moments of this survival distribution are finite, but do not possess closed-form expressions. The standardized fourth central moment, known as Pearson’s coeffi cient of kurtosis and often used to describe the kurtosis of a distribution, can thus also not be expressed in closed form for the logistic-exponent...

A variety of protein domain predictors were developed to predict protein domain boundaries in recent years, but most of them cannot predict discontinuous domains. Considering nearly 40% of multidomain proteins contain one or more discontinuous domains, we have developed DomEx to enable domain boundary predictors to detect discontinuous domains by assembling the continuous domain segments. Disco...

The recent outbreak of Ebola in West Africa will leave a legacy signifi cantly deeper than the morbidity and mortality caused directly by the disease. Ebola deaths have been disproportionately concentrated among health personnel. By May, 2015, 0·02% of Guinea’s population had died due to Ebola, compared with 1·45% of the country’s doctors, nurses, and midwives. In Liberia and Sierra Leone, the ...

We proposed a blind watermarking technique to embed the watermark in JPEG compressed domain. Low frequency DCT coeffi cients are extracted to form an M-dimensional vector. Watermarking is achieved by modifying this vector in order to point to the centroid of a particular cell. This cell is determined according to the extract ed vector, private keys and the watermark. A dual-key system is used t...

where Stock and Watson (call them SW1) impose the restriction that λ = 1, on the assumption that there is a random walk component in trend inflation, with an estimate of θ of at least 0.5, apparently with an upward trend in recent data. In data from 1980 onwards estimates of λ are significantly below unity, but not quantitatively far below, such that Stock and Watson’s (fixed coeffi cient) IMA ...

A self-contained proof is presented of the fact that any increasing, continuous preferences over contingent payoffs that admit a (possibly state-dependent) additive representation are scale (resp. translation) invariant if and only if they take the form of CRRA (resp. CARA) expected utility, with the probabilities and coeffi cient of risk aversion uniquely determined as part of the representati...

Appendix B.1 extends the results in Section 4 on the identification of average exogenous random coeffi cients to study a panel structure and proxies included in the Y equation. Appendix B.2 characterizes the OVB of nonparametric regression and IV methods when U enters the Y and W equations additively separably. Appendix B.3 characterizes the nonparametric regression bias for β̄(x, x∗|x∗, s) and ...

Using the short-term multi-sector econometric model, this paper discusses in detail the multiplier effect of public investment in Japan. After examining its fundamental characteristics, the differ ence in government investment multiplier by the pattern of investment distribution among indus tries and the factors causing such a difference are analyzed. According to the simulation results, the mu...

to date, most studies have focused on continuous aerobic training and there is not comprehensive information about the influence of discontinuous aerobic training on cardiovascular risk biomarkers. taking this into consideration, the purpose of the present study is to investigate the influence of an 8-week discontinuous aerobic training program (3×10 min) on cardiovascular risk biomarkers in in...
