Queenless groups of honey bee workers (Apis mellifera L.) respond with typical increases in their metabolic activity when exposed to queens. Volatile queen odors release 46.8% of the reaction in worker groups compared to combinations of volatile odors and non-volatile factors. Worker groups which were allowed to learn the odor of a given queen were able to discriminate between volatile odors of...

We have proposed, fabricated, and studied a new design of a high-speed optical non-volatile memory. The recoding mechanism of the proposed memory utilizes a magnetization reversal of a nanomagnet by a spin-polarized photocurrent. It was shown experimentally that the operational speed of this memory may be extremely fast above 1 TBit/s. The challenges to realize both a high-speed recording and a...

The volatile components in single-flowered and double-flowered Chinese narcissus were identified by headspace-solid phase microextraction (HS-SPME) coupled with GC and GC/MS. Changes in aroma during the vase-life (days 0, 1, 2, 3, 4, 5 and 6) of two samples were also studied. A total of 35 compounds were identified, of which all were present in single-flowered and 26 in double-flowered samples....

ion decouples the design of NVRAM module from the rest of the development platform and thus facilitates the accommodation of yet-to-come non-volatile memories.

By the end of the decade, computing designs will shift from a processor-centric architecture to a memorycentric architecture. At rack scale, we can expect a large pool of non-volatile memory (NVM) that will be accessed by heterogeneous and decentralized compute resources [3, 17]. Such memory-centric architectures will present challenges that today’s processor-centric OSes may not be able to add...

The virtualized storage stack used in enterprise data centers provides two mechanisms to enable virtualized applications to store and retrieve data, namely, virtual disks and network file systems. In this paper, we examine the pros and cons of using these two mechanisms to integrate emerging non-volatile memory devices, and show how neither of them provide low-overhead access to data without sa...

the volatile components of citrus aurantium l. flowers were characterized by gc-ms with two different extraction techniques, hydrodistillation (hd) and ultrasonic-assisted headspace solid phase microextraction (ua-hs-spme). in the spme method, the volatile components of the samples, irradiated by ultrasonic radiation, were collected on a polydimethyl siloxane (pdms) commercial fiber as well as ...

PURPOSE Marrubium crassidens, a plant belonging to the family Lamiaceae, was studied for its volatile components present in the aerial parts of the plant during the flowering stage. METHODS The essential oil of the plant obtained through hydrodistillation of the dried plant material was assessed for its chemical composition by GC/MS and GC-FID analyses. RESULTS Twenty-five compounds were id...

Korean cabbage, a member of the Brassicaceae family which also includes cauliflower, mustard, radish, and turnip plants, is a crucial leafy vegetable crop. Korean cabbage is harvested after completion of the leaf heading process and is often prepared for use in "baechu kimchi", a traditional Korean food. Many of the components in Korean cabbage are essential for proper human nutrition; these co...
