The impact of pests and diseases on agricultural crops has been amplified due to global environmental changes, resulting in an estimated adverse effect 1.4 trillion dollars, which is approximately 5% the world's gross domestic product. Research was conducted various species parasitic entomophages, such as Aphidius matricaria Hal, gifuensis Ashm, Lysiphlebus japonica Tokawa, ervi fabarum Marsh, ...

A reflex electron beam glow discharge has been used as a plasma source for the generation of broad-area electron beams. An electron current of 120 A ( 12 A/cm2) was extracted from the plasma in 10 ps pulses and accelerated to energies greater than 1 keV in the gap between two grids. The scaling of the scheme for the generation of multikiloamp high-energy electron beams is discussed. E HAVE demo...

We test how donors respond to new information about a charity’s effectiveness. Freedom from Hunger implemented a test of its direct marketing solicitations, varying letters by whether they include a discussion of their program’s impact as measured by scientific research. The base script, used for both treatment and control, included a standard qualitative story about an individual beneficiary. ...

In recent years, with the rapid improvement of the performance of computers, new possibilities for real-time simulation technologies are emerging. In this study, we simulated the behavior of water in real time and combined this simulation with a measurement of the user’s 3D motion to simulate the interaction between water and light, as observed in Noctiluca. Noctiluca is oceanic plankton that p...

The influence of dust particles on the concentration of metastable neon atoms and ionization was investigated using the developed drift/diffusion model for plasma of positive column of glow discharge. The detailed de-excitation in neon was considered. In addition to usual plasma losses in dusty plasmas, the quenching of metastable atoms on dust particle surface was considered. The strong influe...

We are interested in establishing the correspondence between neuron activity and body curvature during various movements of C. Elegans worms. Given long sequences of images, specifically recorded to glow when the neuron is active, it is required to track all identifiable neurons in each frame. The characteristics of the neuron data, e.g., the uninformative nature of neuron appearance and the se...

Charities frequently announce contributions of donors as they accrue. Doing so induces donors to play a sequential-move rather than simultaneous-move game. We examine the conditions under which a charity prefers such sequential play. It is known that if donors only value contributions through their effect on the total provision of a public good, then the charity will not announce contributions ...
