We present an analytical result for the supercurrent across a superconductor/quantum-dot/superconductor junction. By converting the current integration into a special contour integral, we can express the current as a sum of the residues of poles. These poles are real and give a natural definition of the Andreev bound states. We also use the exact result to explain some features of the supercurrent transport behavior.

A dual-sided multiple fans system with a piezoelectric actuator （＂D-MFPA＂）, which is able to drive eight passive vibrating fans and provide two-directional air flows by using only one piezoelectric actuator, has been investigated in this study. Moreover, two types of the fan designs, viz. magnetic fan （MF） and composite magnetic fan （CMF） were also explored. In the investigation of the MF, the results indicated that the resonance frequency of the D-MFPA increased from 27.6 Hz to 66 Hz as the length of the carbon fiber plate （L） decreased from 55 mm to 35 mm. It also decreased the amplitude of the D-MFPA from 12.4mm to 4.8 mm. For CMF, the results showed that the resonance frequency decreased when the length of the Mylar plate （Et） increased, and the maximum decrease was from 66 Hz to 45 Hz when L= 35 mm and Er= 30 mm. Dimensionless heat convection number （MD_MFPA） was defined to describe and quantify the improvement in the thermal performance. The results showed that the optimal MO-MFPA of the single piezoelectric fan was 1,58 for cooling one heat source. By contrast, under the same power consumption, the D-MFPA not only cooled two heat sources but also displayed better thermal performance.

Digital printing brings the tremendous impacts not only to the printing industry but also to the publishing industry. Colleges could establish a “Printing and Publishing Center" to adopt the development of digital printing technology. It is necessary to build up a printing and publishing system to apply the digital printing’s characteristics to fulfill the functions of college education. This system must contain the functions of digital right management (DRM), Internet, and database management system (DBMS). It could print the partial chapters of one of more particular textbooks and publish the books by using the digital printing press in order to present the most updating information. It could fully use the benefits of print-on-demand, variable-data printing, and a short-run printing of digital printing. For the system, it could satisfy the needs of teachers and students in teaching and learning in college.

We present osteological evidence that a rhinocerotid skull belonging to a female Chilotherium wimani was bitten by a giant percrocutid, Dinocrocuta gigantea. Aided by comparative evidence of black rhino (Diceros bicornis) predation by extant spotted hyenas Crocuta crocuta, we interpret the healed wound on the C. wimani female as an injury incurred by the late Miocene D. gigantea. The hunting paleoecology of the giant percrocutid D. gigantea has long been speculated, but thus far no clear evidence has been discovered to point to the predatory habits of this carnivore. The present specimen of C. wimani provides evidence to indicate that the giant percrocutid shared similarities in predatory behavior to the modern spotted hyena: it was an active hunter in spite of the specialized bone-cracking craniodental morphology which imparted superb capability for processing bone.

The aim of this study was to determine the correlation of ultrasonographic estimates of testicular volume with true testicular volume and to compare the accuracy and precision of the three most commonly utilized formulas.A total of 15 patients underwent high-resolution ultrasonography(US)analysis for testicular volume before *** volume was calculated using three common formulas:(1)length(L)×width(W)×height(H)×0.52;(2)the empirical formula of Lambert:L×W×H×0.71;and(3)L×W^(2)×*** actual volume of each removed testis was estimated directly by a water displacement ***,four volume measurements were obtained for each of the 30 *** obtained data were analyzed by paired t-test and linear regression *** three US formula measurements significantly underestimated the true testicular *** largest mean biases were observed with US formula 1,which underestimated the true volume by 3.3 mL(31%).US formula 2 had a smaller mean difference from the true volume,with an underestimation of only 0.6 mL(6%).Regression analysis showed that formulas 1 and 2 had better R^(2) values than formula ***,all three US formulas displayed a strong linear relationship with the true volume(R^(2)=0.872−0.977;P<0.001).Among the commonly used US formulas,the empirical formula of Lambert(L×W×H×0.71)provided better accuracy than the other two formulas evaluated,and better precision than formula ***,the formula of Lambert is the optimal choice in clinical practice.
