With the rapid development of digital and intelligent information systems, display of radar situation interface has become an important challenge in the field of human-computer interaction. We propose a method for the optimization of radar situation interface from error-cognition through the mapping of information characteristics. A mapping method of matrix description is adopted to analyze the association properties between error-cognition sets and design information sets. Based on the mapping relationship between the domain of error-cognition and the domain of design information, a cross-correlational analysis is carried out between error-cognition and design *** obtain the relationship matrix between the error-cognition of correlation between design information and the degree of importance among design information. Taking the task interface of a warfare navigation display as an example, error factors and the features of design information are extracted. Based on the results, we also propose an optimization design scheme for the radar situation interface.

Objective The aim of the study was to detect circulating differentiated thyroid cancer （DTC） micrometas-tasis and to investigate the factors influencing their presence in the perioperative thyroiclectomy period. Methods DTC micrometastases in the peripheral blood were detected with flow cytometry, and patient clinical and pathological factors were analyzed in 327 DTC patients. Results Circulating blood micrometastases were present in the peripheral circulation at a higher rate 1 week postoperatively than preoperatively and at 4 weeks postoperatively （P 〈 0.05）. The preoperative pres- ence of circulating micrometastasis was associated with the size of the tumor and the presence of lymph node metastasis （P 〈 0.05）, but was not related to the degree of tumor differentiation （P 〉 0.05）. At 4 weeks postoperatively, the presence of circulating micrometastasis was not associated with tumor size or lymph node stage （P 〉 0.05）, but was associated with poorly differentiated tumors （P 〈 0.05）. Conclusion The presence of circulating DTC micrometastases correlates to tumor size, lymph node stage, and operative manipulation. The differentiation degree of the tumors were associated with the persistent presence of micrometastasis in the circulating blood.

Profiling of circular RNA N^(6)-methyladenosine in moso bamboo(Phyllostachys edulis)using nanopore-based direct RNA sequencing

Super spreaders play a pivotal role in epidemic propagation. The recent global outbreak of COVID-19, for instance,has been exacerbated by the presence of these super spreaders and alterations in the virus' s infectivity and virulence. This situation escalates the rapid spread of the disease in densely populated and highly mobile cities. Understanding super transmission events, which are instrumental in accelerating epidemic spread, can enhance control strategies for infectious diseases. This paper constructs a dynamic transmission network based on the SIRS model, composed of mobile nodes. It simulates infections caused by typical infected individuals and super spreaders during their movement, as well as aerosol-induced infections. The characteristics of super spreaders will be examined from three perspectives: infection probability, contact radius, and movement speed.

N6-methyladenosine(m^(6)A)is a prevalent modification in messenger RNAs and circular RNAs that play important roles in regulating various aspects of RNA ***,the occurrence of the m^(6)A modification in plant circular RNAs has not been reported.A widely used method to identify m^(6)A modifications relies on m^(6)A-specific antibodies followed by next-generation sequencing of precipitated RNAs(MeRIP-Seq).However,one limitation of MeRIP-Seq is that it does not provide the precise location of m^(6)A at single-nucleotide *** more recent sequencing techniques such as Nanopore-based direct RNA sequencing(DRS)can overcome such limitations,the technology does not allow sequencing of circular RNAs,as these molecules lack a poly(A)***,we developed a novel method to detect the precise location of m^(6)A modifications in circular RNAs using Nanopore *** first enriched our samples for circular RNAs,which we then fragmented and sequenced on the Nanopore platform with a customized *** this method,we identified 470 unique circular RNAs from DRS reads based on the back-spliced junction *** exonic circular RNAs,about 10%contained m^(6)A sites,which mainly occurred around acceptor and donor splice *** study demonstrates the utility of our antibody-independent method in identifying total and methylated circular RNAs using Nanopore *** method has the additional advantage of providing the exact location of m^(6)A sites at single-base resolution in circular RNAs or linear transcripts from non-coding RNA without poly(A)tails.

Objective: To review the evidence for tamsulosin as medical expulsive therapy in enhancing the effectiveness of distal ureteral stone clearance rate. Methods: We searched Pubmed/Medline, Embase, CBM and the Cochrane Library up to October 2011. All randomized controlled trials in which tamsulosin was evaluated with distal ureterolithiasis were eligible for the analysis. Outcome measure assessed was stone clearance rate. Two authors independently assessed study quality and extracted data. All data were analyzed using RevMan 5.1. Results: Thirteen studies involving 1067 participants met the inclusion criteria. Study duration ranged from 7 to 42 d. The pooled analysis showed an improvement of 41% in stone clearance rate of tamsulosin as medical expulsive therapy for distal ureteral calculi (RR=1.41, 95% CI=1.18 to 1.70). According to stone size (6 mm
