We study the negative thermal expansion(NTE) properties and effect of Na insertion on the NTE of the framework material GaFe(CN)6 by first-principles calculations based on density functional theory within the quasi-harmonic approximation. The calculated results show that the material exhibits NTE due to the low transverse vibrational modes of the CN groups. The modes demonstrate larger negative values of the mode Grüneisen parameters. Once Na is introduced in the framework of the material, it prefers to locate at the center of the quadrates of the framework material and binds to the four N anions nearby. As a consequence, the transverse vibrational mode of the CN group is clearly hindered and the NTE of the material is weakened. Our theoretical calculations have clarified the mechanisms of NTE and the effect of the guest Na on the NTE of the framework material. 展开更多

B lymphoma Moloney murine leukemia virus insertion region 1 (BMI1), a core member of polycomb repressive complex 1 (PRC1), has been intensely investigated in the field of cancer epigenetics for decades. Widely known as a critical regulator in cellular physiology, BMI1 is essential in self-renewal and differentiation in different lineages of stem cells. BMI1 also plays a significant role in cancer etiology for its involvement in pathological progress such as epithelial–mesenchymal transition (EMT) and cancer stem cell maintenance, propagation, and differentiation. Importantly, overexpression of BMI1 is predictive for drug resistance, tumor recurrence, and eventual therapy failure of various cancer subtypes, which renders the pharmacological targeting at BMI1 as a novel and promising therapeutic approach. The study on prostate cancer, a prevalent hormone-related cancer among men, has promoted enormous research advancements in cancer genetics and epigenetics. This review summarizes the role of BMI1 as an oncogenic and epigenetic regulator in tumor initiation, progression, and relapse of prostate cancer. 展开更多

A high-performance single-pole single-throw(SPST) RF switch for mobile phone RF front-end modules(FEMs) was designed and characterized in a 0.13 μm partially depleted silicon-on-insulator(PD SOI) process. In this paper, the traditional seriesshunt configuration design was improved by introducing a suitably large DC bias resistor and leakage-preventing PMOS, together with the floating body technique. The performance of the RF switch is greatly improved. Furthermore, a new Ron × Coff testing method is also proposed. The size of this SPST RF switch is 0.2 mm2. This switch can be widely used for present 4 G and forthcoming 5 G mobile phone FEMs. 展开更多

Slot insertion design has proven to be an effective method to increase the bandwidth in the designof microstrip antenna. In this paper, the slot insertion design is applied to the flexible ultra-wideband (UWB)antenna. A flexible rectangular UWB monopole antenna is proposed and fabricated with O-slot design usingthe transfer printing method. By simulating the influence of O-slot design parameters on electromagneticperformance of the antenna, an optimized antenna design is obtained to keep the reflection coefficient under-10 dB with the frequencies ranging from 3.5 to 17.8 GHz when the antenna is bent with curvature radiusas small as 11 mm. The effect of bending on the reflection coefficient is analyzed. Mechanical simulationsindicate that the existence of O-slot can reduce the strain concentration on the metal layer of antenna, whichenhances the flexibility of the antenna. 展开更多

Many countries which seek to understand the acoustic performance of railway noise barriers have established standards for the conduct of in-situ experiments.However,there are no universally acknowledged receiver positions for the evaluation of the barrier performance,a fact which may be leading to uncertainty over the noise reduction capabilities of available barriers.In terms of the descriptor of the barrier performance,the general recommendation is the A-weighted sound pressure level,although the latter is considered to underestimate low frequencies for railway noise barrier.Thus,in this study,the comparison of receiver positions and the descriptors among existing Chinese,ISO and European standards were investigated.Based upon a combination of diffraction theory and standards,a rearrangement of receiver positions and one-third-octave-band analysis were proposed.In addition,in line with improved methods,an in-situ measurement of insertion loss for a 1.5 m high railway noise barrier was designed and conducted.The results of the experiment validate as effective and applicable the new receiver positions.These results also suggest that one-third-octave-band analysis is indispensable. 展开更多

In a periodic real-time system scheduled with the Earliest Deadline First(EDF)algorithm,it is necessary to compress some current tasks to avoid overloading if new task requests to run.Compressing a task means that its period is prolonged while its computation time keeps unchanged.An interesting problem is to find the earliest time to release new tasks without any deadline missing,that is,the earliest smooth insertion time.In this paper,a general frame to calculate the earliest time with multiple rounds of deadline checking is given,which shows that the checking can be done from the request time of the new tasks.A smart way is provided and proved,which takes the value of theΔchecking of the current round as the time step to the next.These techniques potentially reduce the amount of the calculation and the number of the rounds of the checking to get the earliest time.Simulation results are also given to support the conclusion. 展开更多

Genetically modified(GM)organisms are widely adopted.However,their safety assessments and control are still of special concern to the public.Identifying and localizing transgene insertion is an essentially prerequisite step.In this study,2 independent transgene soybean lines were selected(LB4-AtDCGS-1-20-5-2 and CGS-ZG11)as typical cases.Both lines contained expression cassette of At-DCGS that encoding a feedback-insensitive cystathionine gamma-synthase to produce higher level methionine(Met).LB4-At-DCGS-1-20-5-2 was whole genome sequenced with one paired-end 500 bp library and two mate-paired 1 kb and 2 kb libraries using Illumina HiSeq sequencing platform.CGS-ZG11 was sequenced with only one paired-end 500 bp library.Both genomes were assembled,and 2 scaffold sequences(1 for each line)were screened out by aligning with transgene.Then the transgene insertion and its flanking regions in soybean genome were further identified and confirmed by PCR cloning and Sanger sequencing.Results showed that these 2 transgene lines had single copy of inserted transgene.Their transgene insertion contents were identified,which facilitates further safety assessment.These results indicated that genome assembly using high throughput sequencing is a powerful tool for identifying transgene insertions,even with limited knowledge. 展开更多

Long terminal repeat retrotransposons(LTR-RTs) are a predominant group of plant transposable elements(TEs) that are an important component of plant genomes. A large number of LTR-RTs have been annotated in the genomes of the agronomically important oil and vegetable crops of the genus Brassica. Herein, full-length LTR-RTs in the genomes of Brassica and other closely related species were systematically analyzed. The full-length LTR-RT content varied greatly(from 0.43% to 23.4%) between different species, with Gypsy-like LTR-RTs constituting a primary group across these genomes. More importantly, many annotated LTR-RTs(from 10.03% to 33.25% of all detected LTR-RTs) were found to be enriched in localized hotspot regions. Furthermore, all of the analyzed species showed evidence of having experienced at least one round of a LTR-RT burst, with Raphanus sativus experiencing three or more. Moreover, these relatively ancient LTR-RT amplifications exhibited a clear expansion at specific time points. To gain a further understanding of this timing, Brassica rapa, B. oleracea, and R. sativus were examined for the presence of syntenic regions, but none were present. These findings indicate that these LTR-RT burst events were not inherited from a common ancestor,but instead were species-specific bursts that occurred after the divergence of Brassica species. This study further exemplifies the complexities of TE amplifications during the evolution of plant genomes and suggests that these LTR-RT bursts play an important role in genome expansion and divergence in Brassica species. 展开更多
