The present application discloses an evenly heating transducer and a preparation method therefor. The transducer includes a piezoelectric material layer; where the piezoelectric material layer is cylindrical and has a through hole in the middle, a support structure is disposed on an inner side of the through hole, and the piezoelectric material layer and an external device are connected via the support structure. A conductive layer is disposed on a surface of the piezoelectric material layer and an isolation strip is disposed on the conductive layer.

Disclosed is a method of determining efficacy of a cosmetic composition to inhibit an atmospheric pollutant from contacting skin, comprising the steps of: (i) filling a sample holder of known dimensions with known amount of said composition to form a layer of defined thickness therein, where said sample holder is amenable to fluorescence-based assay; (ii) depositing, on said layer, a known amount of a model fine particulate matter which resembles an atmospheric pollutant at least in size and which comprises a material responsive to fluorescence microscopy which is excitable by a wavelength (&#x3bb;) and which emits radiation (&#x3bb;) where (&#x3bb;)&#x2260;(&#x3bb;); (iii) irradiating said composition and said model fine particulate matter by said &#x3bb;and recording intensity of fluorescence at &#x3bb;a plurality of times for a defined period during which said model fine particulate matter interacts with said layer; and, (iv) determining, corrected intensity of fluorescence at &#x3bb;by the following equation; corrected Intensity=recorded intensity/average transmittance where said average transmittance is the average of the transmittance of the composition measured at &#x3bb;and &#x3bb;determined by Beer-Lambert law by measuring the absorbance at &#x3bb;and &#x3bb;, where the corrected intensity is inversely proportional to said efficacy of said composition.

Evaluating the efficacy of leave-on cosmetic compositions to protect skin from pollutants

Techniques for reconstructing a target hierarchy tree structure from profiling data of a computer system according to a predefined relational model, so as to obtain profiling information of a certain selected node. The predefined relational model is defined in advance according to a hierarchy tree structure of the profiling data, and is stored in an external storage system. The hierarchy tree structures can be constructed dynamically as required, thus the occupied amount of a memory can be seduced and users can view the profiling data freely.

Analyzing profiling data based on a rational model

The image data compression method involves the performing of steps: a block dividing step for dividing a computer processor pipeline statistic image to be displayed into a plurality of blocks with predetermined block width and block height; a block list creating step for creating a block list for indexed blocks containing meaningful pixels in the divided blocks such that the indexed blocks are associated with each other, wherein the meaningful pixels are pixels corresponding to the computer processor pipeline raw trace data; and a pixel information compressing step for compressing original pixel information on the meaningful pixels in the indexed blocks and storing it in the block list. Apparatus for performing the method is also provided.
