This paper develops a dielectrophoretic (DEP) chip with multi-layer electrodes and a micro-cavity array for programmable manipulations of cells and impedance measurement. The DEP chip consists of an ITO top electrode, flow chamber, middle electrode on an SU-8 surface, micro-cavity arrays of SU-8 and distributed electrodes at the bottom of the micro-cavity. Impedance sensing of single cells coul...

Security problems in micro-mobility are mostly related to trust establishment between mobile nodes and middle-boxes, i.e. mobile anchor points. In this paper, we present a secure micro-mobility architecture that scales well between administrative domains, which are already using different kind of network access authentication techniques. The trust between the mobile nodes and middle boxes is es...

(1.4) h(x, z) := detΦxz(x, z). If C is locally the graph of a canonical transformation, i.e., h(x, z) 6= 0, then ‖Tλ‖ = O(λ−d/2) (see Hörmander [15], [16]). If the projections have singularities then there is less decay in λ and in various specific cases the decay has been determined. In dimension d = 1 Phong and Stein [21] obtained a complete description of the L mapping properties, for the ca...

Crop coefficients (Kc) are important for the development of irrigation schedules, but few studies on Kc focus on saline soils. To propose the growth-stage-specific Kc values for sunflowers in saline soils, a two-year micro-plot experiment was conducted in Yichang Experimental Station, Hetao Irrigation District. Four salinity levels including non-salinized (ECe = 3.4–4.1 dS·m–1), low (ECe = 5.5–...

In recent years, Indian higher educational institutes grow rapidly. There is more competition between institutes for attracting students to get enrollment in their institutes. The admission process is conducted every year at the institute and it results in the recording of large amounts of data. But, in most of the cases this data is not properly utilized (or analyzed) and results in wastage of...

We examined young adult and late middle-aged male rats to test the hypothesis that gastrocnemius (a locomotor muscle) demonstrates reduced fiber size with aging, whereas soleus (a postural muscle) demonstrates atrophy of some fibers and compensatory hypertrophy in other fibers. Although body mass was greater in late middle-aged animals, mass was reduced in gastrocnemius but not soleus muscle. I...
