Natural arsenic with a unique order structure: potential for new quantum materials

Study of arsenic (As) provides guidelines for the development of next-generation materials. We clarify the unique structure of the third crystalline polymorph of natural As (Pnm21-As) by crystallographical experiment and the electronic structure by first-principles computational method. The crystal structure of Pnm21-As is a novel structure in which the basic portions of semi...

Adaptive Advantage of Myrmecochory in the Ant-Dispersed Herb Lamium amplexicaule (Lamiaceae): Predation Avoidance through the Deterrence of Post-Dispersal Seed Predators

Seed dispersal by ants (myrmecochory) is found worldwide, but the benefits that plants obtain from this mutualism remain uncertain. In the present study, we conducted laboratory experiments to demonstrate seed predator avoidance as a benefit of myrmecochory using the annual ant-dispersed herb Lamium amplexicaule, the disperser ant Tetramorium tsushimae, and the seed predatory...

Influence of Sedimentation of Atoms on Structural and Thermoelectric Properties of Bi-Sb Alloys

Functionally graded thermoelectric materials (FGTMs) have been prepared by sedimentation of atoms under a strong gravitational field. Starting samples of Bi x Sb1−x alloys with different composition x were synthesized by melting of metals and subsequent annealing of quenched samples. The thermoelectric properties (Seebeck coefficient, electrical conductivity) of the starting...

An Endoparasitoid Avoids Hyperparasitism by Manipulating Immobile Host Herbivore to Modify Host Plant Morphology

Many parasitic organisms have an ability to manipulate their hosts to increase their own fitness. In parasitoids, behavioral changes of mobile hosts to avoid or protect against predation and hyperparasitism have been intensively studied, but host manipulation by parasitoids associated with endophytic or immobile hosts has seldom been investigated. We examined the interactions...

Occurrence of Cicadulina bipunctata (Hemiptera: Cicadellidae) in southwestern Shikoku, Japan and comparisons of gall-inducing ability between Kyushu and Shikoku populations

The maize orange leafhopper Cicadulina bipunctata (Melichar) is an insect pest of cereal crops in tropical and subtropical regions of the Old World. This leafhopper induces gall symptoms characterized by stunted growth and swollen leaf veins on various Poaceae. Damage by C. bipunctata has been reported from Australia, the Philippines, China, Taiwan, and Japan. In Japan, C...

Phytohormones Related to Host Plant Manipulation by a Gall-Inducing Leafhopper

The maize orange leafhopper Cicadulina bipunctata (Hemiptera: Cicadellidae) induces galls characterized by growth stunting and severe swelling of leaf veins on various plants of Poaceae. Previous studies revealed that galls are induced not on feeding site but on distant, newly extended leaves during the feeding, and strongly suggested that some chemicals injected by the...

Secondary charged beam lines at the J-PARC hadron experimental hall

Three beam lines for secondary charged particles are constructed in the hadron experimental hall of J-PARC. The K1.8 beam line, which incorporates two separators, delivers clean beams of kaons up to 2 GeV/c. The K1.8BR beam line is a branch of K1.8, for low-momentum particles up to 1.2 GeV/c. The K1.1BR beam line is a shorter line designed for low-momentum kaons. Details of these...
