This paper proposes a method to reduce the supply voltage IR drop of 3D stacked-die systems by implementing an on-chip Buck Converter on Top die (BCT) scheme. The IR drop is caused by the parasitic resistance of Through Silicon Vias (TSV’s) used in the 3D integration. The IR drop reduction and the overhead associated with the BCT scheme are modeled and analyzed. A 3D stacked-die system is manuf...

the aim of this paper is to extend results established by h. onoand t. kowalski regarding directly indecomposable commutative residuatedlattices to the non-commutative case. the main theorem states that a residuatedlattice a is directly indecomposable if and only if its boolean center b(a)is {0, 1}. we also prove that any linearly ordered residuated lattice and anylocal residuated lattice are d...

Combination of solid-phase microextraction with gas chromatography enables rapid, repeated analysis of organic compounds in water. Fluazifop-p-butyl (FPB) (propanoic acid 2-[4-[[5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy] butyl ester) is the active substance in the herbicide Fusilade. Samples of distilled water were spiked with FPB in the laboratory and the analyte was isolated from the water ...

Novel field effect transistors with suspended graphene gates are demonstrated. By incorporating mechanical motion of the gate electrode, it is possible to improve the switching characteristics compared to a static gate, as shown by a combination of experimental measurements and numerical simulations. The mechanical motion of the graphene gate is confirmed by using atomic force microscopy to dir...

The recent increase in the notifications of tuberculosis infections has focused the attention of healthcare professionals on reasons for the disease's resurgence. This article describes how directly observed therapy and an enlightened approach to health promotion for groups of people perceived as being at risk, could prevent further increases in incidence.

A new direct method has been developed to determine protein-drug binding based on hollow fiber membrane solvent microextraction. Hollow-fiber membrane solvent microextraction coupled with high-performance chromatography with UV detection was employed to evaluate the binding characteristics of drugs to bovine serum albumin (BSA) and blood serum. It was found that the BSA and matrix in the blood ...

Wetting of simple liquids on rough surfaces is usually described either by the Cassie–Baxter model where drops are suspended over roughness features with air trapped below, or Wenzel impaled features. According to model, can be surfaces, whereas in easily released upon adding a small tilt. Surfaces very regular surface pattern, such as closely spaced micro-trenches, exhibit so-called High Hyste...
