believe that a hallmark of good science is that it can be explained concisely in simple, jargon-free terms to a non-scientist. Karl von Frisch, the famous Nobel laureate who championed the study of honeybee behaviour, is said to have commented that a good scientific seminar should be organized in three parts. The first part should consist of material that the audience already knows, so that the...

Low-energy g-ray spectra were collected from Am, Co, Ba, Au, Cs and U using a 3.4 3.4 5.7mm CdZnTe detector utilizing an insulated Frisch ring. The CdZnTe detector was fabricated from a single crystal and a copper shim was used as the Frisch collar. Room-temperature energy resolution of 1.45% full-width half-maximum (FWHM) was obtained for Cs at 661.7 keV without electronic correction. The dete...

background: people’s quality of life plays an important role in their life satisfaction and life satisfaction is an important factor in the mental health of the society. therefore, knowing efficient and effective methods and techniques that can be effective in increasing the quality of life, is considered as an important step in improving individuals ‘satisfaction and increasing their mental he...

A collimated Au source was used to determine the charge collection efficiency (CCE) at several locations along the length of a 3.4 x 3.4 x 5.5 mm CdZnTe bar detector both in planar configuration and with Frisch collars of varying length. For each configuration, a 0.50 mm long region spanning the width of the device was irradiated with 411 keV gamma rays produced by a neutron activated gold foil...

In his 1950 book Bees: Their Vison, Chemical Senses, and Language, Karl von Frisch recounts his decades of research into how honey bees perceive the world, concluding “The bee’s life is like a magic well: the more you draw from it, the more it fills with water.” (von Frisch, 1950). Sixty-five years on, science continues to draw from that magical well, and we have learned a tremendous amount abo...

This paper describes a new approach for identifying autoregressive models from a finite number of measurements, in presence of additive and uncorrelated white noise. As a major novelty, the proposed approach deals with frequency domain data. In particular, two different frequency domain algorithms are proposed. The first algorithm is based on some theoretical results concerning the so–called dy...

This paper generalizes the model of Becker, Grossman, and Murphy (1994) to the multivariate case. The multivariate model generates Frisch demand functions where current consumption is related to prices of all goods, and lagged and future consumption of all goods. The theoretical restrictions are that current price effects (holding lagged and future consumption constant) are negative definite, a...
