Experiments and Discussion
We selected a set of cardiac CT data from the clinical data of the Chinese PLA General Hospital to verify the interactive system of the proposed medical 3D model.
First, we used VTK to perform pseudo-color processing on cardiac data.
Leap Motion could provide considerable data of fingers, palms, wrists, and elbows.
Data sampling was performed in a circle of 1s by analyzing the results.
Rotation The judgment criteria of rotation were the absolute difference between two adjacent roll data.

Tobacco (Nicotiana tabacum L.) is able to accumulate cadmium in leaves and reduction of cadmium content can reduce health hazards to smokers.
Data are presented as mean.
The presence of Cd also caused a reduction of the number of tobacco leaves and the largest leaf area (Fig. 1).

Accordingly, after 18 h of exposure, the impact energy decrement was determined at 31.5%, at a current density of 10 mA/cm2, whereas the corresponding reduction at 20 mA/cm2 reached 68%.
The data was collected over an extended period of time since the X-ray beam was directed onto the sample for an extended period of six sec per step (0.02o), thus allowing a more precise and detailed analysis of the crystallographic structure of steel specimens.
According to the results, hydrogen uptake caused a reduction in Charpy impact energy at higher current density, with the highest reduction to be measured at 20 mA/cm2 for 18h.
With increasing the current density and time of exposure, the severity of the observed fractures increased along with the corresponding impact energy reduction.
Ø Accordingly, hydrogen uptake caused a reduction in Charpy impact energy at higher current density.

A Hybrid Algorithm for Fast Detection and Resolution of Generalized Deadlocks in Distributed Systems

This paper proposes an algorithm which incorporates these two methods with the
following properties: first, it removes the reduction phase of the diffusing computation; second, it
encodes the dependency information to reduce message length, rather than transmitting it naively as
is.
We remove the reduction phase of reply propagation in the first type: that is, the proposed algorithm lets probes rather than replies carry the dependency information in order to expedite the detection activity.
It is the first algorithm that eliminates the reduction phase of the diffusing computation but is still able to detect deadlock without collecting all dependency information naively.
