We have continuously imaged the controlled motion of a single atom as well as of a small number of distinguishable atoms with observation times exceeding one minute. The Cesium atoms are confined to potential wells of a standing wave optical dipole trap which allows to transport them over macroscopic distances. The atoms are imaged by an intensified CCD camera, and spatial resolution near the d...

A new approach for an electrically driven microlaser based on a microdisk transferred onto Silicon is proposed. The structure is based on a quaternary InGaAsP p-i-n junction including three InAsP quantum wells, on a thin membrane transferred onto silicon by molecular bonding. A p++/n++ tunnel junction is used as the p-type contact. The technological procedure is described and first experimental...

To the Editor, The Indian Medical Gazette. Sir,?In some villages near Mandya in Mysore District, a few cases of dysentery were reported and the health officer in charge of the rural unit sent seven motions from patients suffering from the attack, and two water samples from wells that were reported to have caused dysentery after use, for bacteriological analysis. A relevant portion of this lette...

Bu çal??mada, Kapadokya Bölgesi’nin kamp turizmi aç?s?ndan mevcut durumunu incelemek ve bu kapsamda yeni bir turizm türü olarak glamping kapsam?nda bölgenin neler yapabilece?ine ili?kin öneriler sunabilmek amaçlanmaktad?r. Çal??mada birincil ikincil veriler kullan?lm??t?r. Birincil yar? yap?land?r?lm?? mülakatlardan, ise daha önce yap?lm?? çal??malardan elde edilmi?tir. verilerle GZTF (SWOT) an...

Blue shift of the heavy-hole peak of the photocurrent spectra has been observed, for the first time, in narrow GaAs/Alc4Ga.e6As asymmetric coupled quantum wells near the heavyhole resonance. With an external reverse bias of only 2.35 V, a maximum upward shift of the apparent peak position of 6.1 meV has been measured at 78 K. Sharp change of the inhomogeneous linewidth of the heavy-hole peak ha...
