1. THE COMPOSED ZERO TRUNCATED LINDLEY-POISSON DISTRIBUTION
ABSTRACT In this paper, a new compounding distribution, named zero truncated Lindley-Poisson distribution is introduced. The probability density function, cumulative distribution function, survival function, failure rate function and quantiles expressions of it are provided. The parameters estimatives were obtained by six methods: maximum likelihood (MLE), o

2. A DISTRIBUTION FOR THE SERVICE MODEL
ABSTRACT In this paper, we propose a distribution that describes a specific system. The system has a heavy traffic, a fast service and the service rate depends on state of the system. This distribution we call the Maximum-Conway-Maxwell-Poisson-exponential distribution, denoted by MAXCOMPE distribution. The MAXCOMPE distribution is obtained by compound distr

3. Estimação clássica e bayesiana para relação espécieárea com distribuições truncadas no zero
Em ecologia, a compreensão da relação espécie-área (SARs) é de extrema importância para a determinação da diversidade de espécies e avaliar o impacto devido à destruição de habitats naturais. Neste estudo, observa-se o número de espécies em diferentes tamanhos de área. Estes estudos são abordados na literatura através de modelos não linear

4. Some goodness-of-fit methods for the Poisson plus added zeros distribution.
Methods for making inferences about the Poisson plus added zeros distribution and the truncated Poisson distribution are presented and illustrated with bacteriological data. Some of the methods are designed for testing the compatibility of the zero frequency with the Poisson distribution, whereas others are given for testing the goodness of fit for the trunc

5. Single-channel recordings of three types of calcium channels in chick sensory neurones.
1. T-, and L-type Ca2+ channels were studied in cell-attached patch recordings from the cell bodies of chick dorsal root ganglion neurones. All experiments were performed with isotonic BaCl2 (110 mM) in the recording pipette and with isotonic potassium aspartate in the bathing solution to zero the cell membrane potential. 2. L-type channels are distinguished

6. Single-channel measurement from the cyclic GMP-activated conductance of catfish retinal cones.
1. A patch of plasma membrane was excised, in the inside-out configuration, from the outer segment tip of a catfish cone and recorded electrically with a patch pipette. A solution of 118 mM-NaCl was present on both sides of the membrane. 2. With the solution outside the pipette containing a low concentration (typically several micromoles per litre) of cyclic

7. Non-stationary fluctuations of the potassium conductance at the node of ranvier of the frog.
Potassium currents were recorded from voltage-clamped nodes of isolated, myelinated axons of Rana pipiens. Nodes were maintained in a modified Ringer solution containing tetrodotoxin to block sodium current and 47.5 mM-potassium to minimize effects of extracellular potassium accumulation. Voltage protocols included depolarizing pulses lasting a few milliseco

8. Reflex responses at the human ankle: the importance of tendon compliance.
Subjects with active stretch reflexes responded to an imposed sinusoidal movement of the ankle joint with a reflex force whose amplitude and timing varied widely with changes in the frequency of movement. At some frequency between 6 and 8 Hz, the reflex force tended to offset the non-reflex component of resistance, and thus to reduce the total resistance to

9. Open-state substructure of inwardly rectifying potassium channels revealed by magnesium block in guinea-pig heart cells.
1. Outward single-channel currents through inwardly rectifying K+ channels of cardiac myocytes were studied in the open cell-attached configuration to clarify the mechanism of the rectification. The outward currents, which were not recorded in the cell-attached configuration, appeared after the inner surface of the patch was exposed to low-Mg2+ solution by r
