Growing evidence indicates that small, secreted peptides (SSPs) play critical roles in legume growth and development, yet the annotation of SSP-coding genes is far from complete. Systematic reannotation of the Medicago truncatula genome identified 1,970 homologs of established SSP gene families and an additional 2,455 genes that are potentially novel SSPs, previously unreported in the literatur...

The composition of the essential oil from ripe and unripe berries and leaves of Juniperus oxycedrus L. ssp. oxycedrus, Juniperus phoenicea ssp. turbinata and Juniperus communis ssp. communis was analyzed by GC-MS, and microbiological assays were carried out. Samples were collected in different localities (Sardinia, Italy) and hydro distilled. The yields ranged between 2.54% +/- 0.21 (v\w dried ...

The formation/loss of characterized traits in a given cultivated species is strongly affected by long-term artificial selection. Cowpea (V. unguiculata L. Walp.) is an important legume crop for many residences in the tropics and subtropics of the world, being consumed as either a grain, fodder or vegetable crop depending on local cultivation and consumption habits. Cowpea is believed to have or...

To provide constraints on the inversion of ocean sound speed profiles (SSPs), SSPs are often modeled using empirical orthogonal functions (EOFs). However, this regularization, which uses the leading order EOFs with a minimum-energy constraint on the coefficients, often yields low resolution SSP estimates. In this paper, it is shown that dictionary learning, a form of unsupervised machine learni...

Euclidean distance, Hausdorff distance and SSP distance are discussed, and SSP distance is used to improve Isomap algorithm. Two methods are put forward for improving Isomap algorithm. One is aligning input data of original Isomap algorithm, the other is modifying Isomap algorithm itself. SSP distance is used to search neighbors and compose neighborhood graph, and the plot for each dimension of...

This paper investigates authentication and secure data retrieval issues in Radio-Frequency IDentification (RFID)-aware wireless sensor networks. We propose a network architecture (ARIES) consisting of RFIDs and wireless sensor nodes, a mutual authentication protocol (AMULET), and a Secret Search Protocol (SSP). ARIES utilises RFID-aware sensor nodes to alleviate distance limitation problem in R...

Background: In current study, chemical composition and antibacterial activity of leaves and flowers essential oils of Origanum vulgare ssp. gracile against four food-borne pathogens including  Escherichia coli, Listeria monocytogenes, Salmonella thyphimurium and Staphylococcus aureus were examined. Methods: The different organs (leaves and flowers) of O. vulgare ssp. gracile were har...

Neurokinins, such as substance P (SP), modulate the reflex regulation of cardiovascular and respiratory function in the CNS, particularly in the nucleus tractus solitarius (NTS). There is considerable evidence of the action of SP in the NTS, but the precise effects have not yet been determined. Voltage-dependent Ca2+ channels (VDCCs) serve as crucial mediators of membrane excitability and Ca2+ ...
