The accuracy of multibeam echosounder bathymetric measurement depends on the data sound speed layers within water column. This is necessary for correct modeling ray bending. It assumed that are horizontal and static, according to profile traditionally used in depth calculation. In fact, boundaries between varying masses can be curved oscillate. difficult assess parameters these movements based ...

Information concerning the location and distribution of presynaptic neurotransmitter release sites within anatomically labeled axons would be of value for a large number of studies in functional anatomy, development, and plasticity. Here we report a method for localizing presynaptic sites within identified arbors of interest using anterograde anatomical tracer injections to label axonal project...

The annual growth cycle of trees is the result of seasonal cues. The onset of winter triggers an endodormant state preventing bud growth and, once a chilling requirement is satisfied, these buds enter an ecodormant state and resume growing. MADS-box genes with similarity to Arabidopsis SHORT VEGETATIVE PHASE (SVP) [the SVP-like and DORMANCY ASSOCIATED MADS-BOX (DAM) genes] have been implicated ...

The role in flowering time of the MADS-box transcription factor fruitfulL (FUL) has been proposed in many works. FUL has been connected to several flowering pathways as a target of the photoperiod, ambient temperature, and age pathways and it is has been shown to promote flowering in a partially redundant manner with suppressor of overexpression of constans 1 (SOC1). However, the position of FU...

In this work we study speed-ups and time–space trade-offs for solving the shortest vector problem (SVP) on Euclidean lattices based on tuple lattice sieving. Our results extend and improve upon previous work of Bai–Laarhoven– Stehlé [ANTS’16] and Herold–Kirshanova [PKC’17], with better complexities for arbitrary tuple sizes and offering tunable time–memory tradeoffs. The trade-offs we obtain st...

PURPOSE The contamination rates associated with the preparation of medium-risk i.v. admixtures in a traditional practice site and in a class 1000 cleanroom were compared. METHODS Simulated product media fills served as the samples. Each investigator, a pharmacist and a pharmacy technician, prepared 500 vials and 500 small-volume parenteral (SVP) bags in five separate runs at a traditional pra...

An n-dimensional lattice is the set of all integral linear combinations of n linearly independent vectors in ' tm. One of the most studied algorithmic problems on lattices is the shortest vector problem (SVP): given a lattice, find the shortest non-zero vector in it. We prove that the shortest vector problem is NP-hard (for randomized reductions) to approximate within some constant factor great...

In the mosquito Aedes aegypti, vitellogenesis is activated via an ecdysteroid hormonal cascade initiated by a blood meal. The functional ecdysone receptor is a heterodimer composed of the ecdysone receptor (EcR) and ultraspiracle, the homolog of the retinoid X receptor. The precise tuning of this hormonal response requires participation of both positive and negative transcriptional regulators. ...

Purpose. Nowadays, in Quang Ninh coalfield, the mining activity quarries is increasing. For this purpose, mine roadways are dug and supported. After dug, they mainly supported by steel arches. Statistics fact show that about 85 % of roadway support structure at underground coal mines arch made SVP profile. The purpose study to calculate determine a reasonable distance for located under open-pit...
