influence of 13 soybean cultivars (356, m4, m7, m9, clark, sahar, jk, bp, williams, l17, zane, gorgan3 and dpx) on the life table parameters of the cotton bollworm, helicoverpa armigera (hã¼bner) was studied at 25 â± 1â°c, relative humidity of 65 â± 5% and a photoperiod of 16: 8 (l: d) h. the survival rate (lx) of individuals developed to adults from the initial cohort on the mentioned cultivar...

the common green lacewing is an important natural enemy used for pest control in greenhouses. it is also very common in many agricultural systems. hence, studying lethal and sublethal effects of insecticides on this predator would be useful. toxicity of endosulfan, imidacloprid and indoxacarb was assessed on 1st instar larvae of chrysoperla carnea (stephens) in laboratory. residual bioassays we...

Predictors are inevitable components in the state-of-theart microprocessors and branch predictors are actively discussed from many aspects. Performance of a branch predictor largely depends on the dynamic behavior of the executing program, however, we have no effective metrics to represent the nature of program behavior quantitatively. In this paper, we introduce an information entropy idea to ...

It is well known that the origin-destination (O-D) flow table of a subnetwork is not only determined by trip generation and distribution, but also by traffic routing and diversion, due to the existence of internal-external, external-internal and externalexternal flows. This result indicates the variable nature of subnetwork O-D flows. This paper discusses an elastic O-D flow table estimation pr...

the side-effects of amitraz, buprofezin and propargite were studied on encarsia formosa (gahan)in the laboratory, using a life table response experiment and the iobc system for their toxicity. bioassayswere conducted by dipping bean leaves containing third instar nymphs of the whitefly trialeurodesvaporariorum (westwood), parasitized by e. formosa, in insecticide solutions or caging adult paras...

t Parametric models for the entire age pattern of mortality have been suggested by Heligman and Pollard (1980) and Carriere (1992). The former is designed to fit the classical mortality pattern while the latter is supported by a statistical theory. Insights into their papers motivate us to consider a variation of the Heligman-Pollard model. We also apply these models to the 1993 Hong Kong Assur...

OBJECTIVES To explore various methods to quantify the burden of mortality, with a special interest for the more recent method at the core of calculations of disability adjusted life years (DALY). DESIGN Various methods calculating the age schedule at death are applied to two historical life table populations. One method calculates the "years of life lost", by multiplying the numbers of deaths...

In this paper, we propose a maximum entropy-based model, which can mathematically explain the biomolecular event extraction problem. The proposed model generates an event table, which can represent the relationship between an event trigger and its arguments. The complex sentences with distinctive event structures can be also represented by the event table. Previous approaches intuitively design...

Fatigue damage is an irreversible progression which can be represented by the entropy increase, and it is well known that the second law of thermodynamics can describe an irreversible process. Based on the concept of entropy, the second law of thermodynamics can provide the changing direction of system. In the current study, a new entropy increment model is developed based on the frame work of ...
