Differential unitary space-time modulation （DUSTM）, which obtains full transmit diversity in slowly fiat-fading channels without channel state iufonnation, has generated significant interests recently. To combat frequency-selective fading, DUSTM has been applied to each subcarrier of an OFDM system and DUSTM-OFDM system was proposed. Both DUSTM and DUSTM-OFDM, however, are designed for slowly fading channels and suffer performance deterioration in fast fading channels. In this paper, two novel differential unitary space-time modulation schemes are proposed for fast fading channels. For fast fiat-fading channels, a subatrix interleaved DUSTM （SMI-DUSTM） scheme is proposed, in which matrix-segmentation and sub-matrix based interleaving are introduced into DUSTM system. For fast frequency-selective fading channels, a differential unitary space-frequency modulation （DUSFM） scheme is proposed, in which existing unitary space-time codes are employed across transmit antennas and OFDM subcarriers simultaneouslv and differential modulation is performed between two adjacent OFDM blocks. Compared with DUSTM and DUSTM-OFDM schemes, SMI-DUSTM and DUSFM-OFDM are more robust to fast channel fading with low decoding complexity, which is demonstrated by performance analysis and simulation resuits.

In this study,we prepared Fe_(2)O_(3)-Nb_(2)O_(5)binary mixed oxide catalysts using co-precipitation(CP),sol-gel(SG),and solid process(SR)methods and tested their *** the catalysts exhibited over 75%NO_(x)removal efficiency between 250℃and 400℃.Compared with the samples prepared by the SR method,catalyst synthesized using CP and SG methods possessed a larger specific surface area,which could compensate for the lower surface area-normalized reaction rate originat-ing from the insufficient reactive surface oxygen species,hence exhibiting a relatively high low-temperature apparent deNO_(x)***,at a high-temperature region,limited amount of reactive surface oxygen species,together with abundant strong acid sites,facilitated the proceeding of NH_(3)reduction of NO_(x),which well explained the higher apparent activity of the catalyst prepared by SG method than the other two *** seemed that specific surface area had an important role to play in the low-temperature apparent performance of the catalysts,while chemical properties mainly decided the activity at an elevated temperature.

The sequestosome 1/p62 protein has been implicated in the regulation of a multitude of cellular processes such as NF-κB signaling, NRF2-driven oxidative stress response, protein turnover through the ubiquitin-proteasome pathway and the autophagosome/lysosome pathway, apoptosis and cellular metabolism. The domain structure of p62 also reflects this functional complexity since the protein appears to be a mosaic of protein interaction domains and motifs. Deregulation of the level and function of p62 and/or p62 mutations have been linked to a number of human diseases including Paget＇s disease of the bone, obesity, liver diseases, tumorigenesis and neurodegenerative diseases such as amyotrophic lateral sclerosis and Alzheimer＇s disease. In this article, we review the current understanding of the involvement of p62 in cellular processes under physiologic and pathological conditions.

OBJECTIVE: To investigate the effect of electroacupuncture(EA) at acupoints on the pericardium meridian on the expression of phosphorylated Akt(p-Akt) protein in rat myocardium after ischemia and ***: Seventy Wistar rats were evenly randomized into seven groups: the sham operation group(group A), ischemia-reperfusion model Ⅰgroup(group B), ischemia-reperfusion model Ⅱgroup(group C), EA at Neiguan(PC 6) group(group D), EA at Ximen(PC 4) group(group E), EA at Hegu(LI 4) group(group F), and LY294002 + EA at Neiguan(PC 6) group(group G). All processes were monitored by electrocardiography. In group A, the left anterior descending coronary artery was only threaded without ligation for 100 min. In group B,the left anterior descending coronary artery was ligated for 40 min and reperfused for 60 min. The left anterior descending coronary artery in group C was ligated for 40 min and reperfused for 100 *** D, E, and F received EA for 20 min before undergoing ischemia for 40 min, and then received EA for 20 min before undergoing reperfusion for 60 min. Before modeling, group G was injected with LY294002(0.3 mg/kg) into the tail vein, and then underwent the same intervention as the other EA groups. After reperfusion, myocardial tissue from the left cardiac ventricle was collected to enable Western blot analysis of the p-Akt level, and analysis of electrocardiographic ***: In groups B and C, electrocardiography showed obvious elevation of the ST-segment Ⅱlead(ECG-STⅡ), while the ECG-STⅡvalues were significantly lower in groups D, E, and G(P < 0.01). The p-Akt levels in groups D and E were significantly greater than those in groups B and C(P < 0.01).Compared with all other groups, group G showed a significantly different expression of p-Akt(P < 0.01).CONCLUSION: The expression of p-Akt protein in cardiomyocytes was significantly greater in rats that were injected with LY294002 and received EA at Ximen(PC 4) compared with all other *** su
