Although LTE-Advanced system is targeted at enhancing the users’ throughput and increasing connection reliability, however user’s mobility tends to degrade the efficiency of the services and applications in terms of throughput degradation and outage probability reduction. Particularly this is during the handover from the source to the target eNBs. Therefore, the Carrier Aggregation (CA) techniq...

Affinity monolith chromatography (AMC) is a type of liquid chromatography that uses a monolithic support and a biologically related binding agent as a stationary phase. AMC is a powerful method for the selective separation, analysis, or study of specific target compounds in a sample. This review discusses the basic principles of AMC and recent developments and applications of this method, with ...

Weather critically influences fire behaviour. Antecedent conditions control availability and moisture content of the fuels, and thus influence the likelihood of ignition. Once a fire is established, its behaviour is influenced by temperature, humidity and wind. Of these, fire behaviour is perhaps most sensitive to changes in wind speed, as evidenced by the sensitivity of the McArthur Forest Fir...

In this paper, we propose a Double-Space Time Transmit Diversity (D-STTD) communication system with Adaptive Modulation and Coding (AMC) scheme and analyze its performance using simulation experiments. The simulation results show that the probability of selecting a high Modulation and Coding Scheme (MCS) level increased as the Signal to Noise Ratio (SNR) improved. Furthermore, the D-STTD commun...

German pronouns (er(MALE/masculine), sie(FEMALE/feminine)) that refer to a person are determined by the biological gender (MALE/FEMALE) and/or syntactic gender (masculine/feminine) of the person. Pronouns (er(masculine), sie(feminine)) that refer to a thing are determined by the syntactic gender of this thing (Garten [garden]masculine, Tasche [hand-bag]feminine). The study aimed to investigate ...

Background: We have reported that arterial micro-calcification (AMC) of vascular access has a negative impact on access patency and cardiovascular mortality in hemodialysis (HD) patients. Because AMC is diagnosed by histologic examination, it cannot be commonly performed. Coronary artery calcification (CAC) is quite common and known risk factors of cardiovascular mortality in HD patients. It ca...

To improve the robustness and reliability of wireless transmissions, two complementary link adaptation techniques are employed: adaptive modulation and coding (AMC) at the physical layer and hybrid automatic retransmission request (HARQ) at the medium access control layer. Because of their effectiveness in combating errors induced by the wireless channel, AMC and HARQ are now integral component...

The monitoring of both cold and warm season hydrologic processes in headwater watersheds is critical for accurate water resource monitoring in many alpine regions. This work presents a new method that explores the simultaneous use of remotely sensed surface soil moisture (SM) and snow depth (SD) retrievals to improve hydrological modeling in such areas. In particular, remotely sensed SM and SD ...

in today's world, quality improvement of basic medical education is a must for training physicians who are able to meet the growing health needs of our society. one way for quality assurance in higher education including medical education is to develop a system of accreditation which has been in medical education authorities' constant focus recently. this article is a review of national accredi...
