Cryopreservation of plant tissues in liquid nitrogen is now used for long-term conservation of vegetatively-propagated crops. Development of standard techniques for cryopreservation is important to the international plant-conservation community for successful implementation of storage protocols in diverse and internationally dispersed laboratories. Evaluation of the critical points of each pres...

Objective Women undergoing IVF cycles should go successfully through multiple points during the procedure (i.e., implantation, clinical pregnancy, no spontaneous abortion and delivery) to achieve live births. On the other there is a need to consider previous reproductive outcomes and as well as the current cycle. In this study, data on multiple cycles and multiple points during the IVF cycle ar...

This work presents new frequency-domain methods for the analysis and simulation of circuits based on a nonlinear resonator, with operation ranges delimited by turning points. Insightful analytical conditions fulfilled at these points are derived, which will enable an identification effect each circuit element their location in solution curve. The cusp points, or co-dimension two bifurcations me...

In real applications, there are situations where we need to model some problems based on uncertain data. This leads us to define an uncertain model for some classical geometric optimization problems and propose algorithms to solve them. In this paper, we study the k-center problem, for uncertain input. In our setting, each uncertain point Pi is located independently from other points in one of ...

OBJECTIVE To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on pregnancy rates (PR) in women undergoing ET. DESIGN Prospective, randomized, single-blinded placebo-controlled clinical trial. SETTING Research and laboratory facilities. PATIENT(S) A total of 309 patients, less than 45 years old, undergoing cryopreservation embryos transplant or fresh cycle IVF w...

double-diffusive mixed convection in a lid-driven square enclosure filled with al2o3-water is numerically investigated. two-dimensional nonlinear governing equations are discretized using the control volume method and hybrid scheme. the equations are solved using simpler algorithm. the results are displayed in the form of streamlines, isotherms, and iso-concentrations when the richardson number...

in this study, mixed convection heat transfer and local and global entropy generation in aventilated square cavity have been investigated numerically. the natural convection effect isachieved by a constant heat flux imposed at the bottom wall and cooled by injecting a coldfollow. in order to investigate the effect of port location, four different placementconfigurations of the inlet and outlet ...

Location-based services, navigation applications, emergency services, management of equipment in the field, and other locationdependent services need geographic location information about a Target (such as a user, resource or other entity). There is a need to securely gather and transfer location information for location services, while at the same time protecting the privacy of the individuals...

Our mental representation of the world is far from objective. For example, western Canadians estimate the locations of North American cities to be too far to the west. This bias could be due to a reference point effect, in which people estimate more space between places close to them than far from them, or to representational pseudoneglect, in which neurologically intact individuals favor the l...
