We propose a technique to assess the vulnerability of the power system state estimation. We aim at identifying the measurements that have a high potential of being the target of false data injection attacks. From the perspective of the adversary, such measurements have the following characteristics: ① being influential on the variable estimates;② corrupting their measured values is likely to be undetected. Additionally, such characteristics should not change significantly with the system operation condition. The proposed technique provides a systematic way of identifying the measurements with such characteristics. We illustrate our methodology on a 4-bus system, the New England 39-bus system, and the IEEE 118-bus test system, respectively.

A study was conducted to evaluate the effect of the dietary inclusion of full-fat flaxseed of full-fat sunflower seeds on performance parameters,egg quality parameters and egg yolk fatty acid profile in laying hens.A total of 150 Babcock Brown hens at 27 weeks of age were distributed in 3 experimental treatments,as follows:T1,control;T2,diet containing 13.5% full-fat whole flaxseed seeds;and T3,diet containing 13.5% full-fat ground sunflower *** and water were provided ad libitum and the experiment lasted for 8 *** significant differences were found on egg quality parameters,but total egg production and rate of lay were significantly(P <0.05) lower in the group receiving sunflower seeds compared with the control,and significant differences(P <0.05) in egg yolk saturated,monounsaturated,polyunsaturated,omega-6(n-6) and omega-3(n-3) fatty acids were observed,as well as in the n-6:n-3 *** results show that the dietary inclusion of 13.5% flaxseed full-fat seeds significantly increases the n-3 polyunsaturated fatty acid(PUFA) content in the eggs and lowers the n-6:n-3 ratio without affecting performance *** of full-fat sunflower seeds increases the n-6 PUFA content but affects total egg production and rate of *** studies are needed to determine the level of inclusion of full-fat sunflower seeds that does not affect performance.

As-cast HK40 steel was aged at 700, 800, or 900℃ for times as long as 2000 h. Microstructural characterization showed that the primary M_7C_3 carbide network contained a substantial content of manganese, in agreement with the microsegregation of manganese calculated by Thermo-Calc using the Scheil–Gulliver module. The dissolution of primary carbides caused the solute supersaturation of austenite and subsequent precipitation of fine M_(23)C_6 carbides in the austenite matrix for aged specimens. During prolonged aging, the carbide size increased with increasing time because of the coarsening process. A time–temperature–precipitation diagram for M_(23)C_6 carbides was calculated using the Thermo-CalcPRISMA software; this diagram showed good agreement with the experimental growth kinetics of precipitation. The fine carbide precipitation caused an increase in hardness; however, the coarsening process of carbides promoted a decrease in hardness. Nanoindentation tests of the austenite matrix indicated an increase in ductility with increasing aging time.

Many applications, including optical multiplexing, switching, and detection, call for low-cost and broadband photonic devices with polarization-independent operation. While the silicon-on-insulator platform is well positioned to fulfill most of these requirements, its strong birefringence hinders the development of polarizationagnostic devices. Here we leverage the recently proposed bricked metamaterial topology to design, for the first time, to our knowledge, a polarization-independent 2 × 2 multimode interference coupler using standard 220 nm silicon thickness. Our device can be fabricated with a single etch step and is optimized for the O-band,covering a wavelength range of 160 nm with excess loss, polarization-dependent loss, and imbalance below 1 dB and phase errors of less than 5°, as demonstrated with full three-dimensional finite-difference time-domain simulations.

Objective： To study the main clinical and histopathological features of 12 patients with Hodgkin＇s lymphoma （HL） diagnosed primarily from bone marrow （BM） involvement. Methods： We included 12 acquired immunodeficiency syndrome （AIDS） patients with HL assisted in the F. j. Mufiiz Infectious Diseases Hospital since january 2002 to December 2013. The diagnosis of ilL with primary BM involvement in patients was confirmed by clinical, histopathological, and immunohistochemical findings. Results： All patients presented ＂B＂ symptoms and pancytopenia. All of them had stage IV neoplasm disease because of BM infiltration. The median of CD4＋ T-cell counts was 114 cells/μL, and mixed cellularity （MC） was the most frequent histopathological subtype of 92% cases. Conclusion： When other causes are excluded, BM biopsy should be performed in AIDS patients with ＂B＂ symptoms and pancytopenia to evaluate BM infiltration by atypical lymphocytes.
