Long life green emitting matrix display based on organic light emitting diode is reported. The pixel number is 96×60, equivalent pixel size 0.4×0.4 mm 2, and the pixel gap 0.1 mm. An image with no crosstalk between pixels is obtained. The average luminance of these pixels at duty cycle of 1/64 is 100 cd/m 2, and the power consumption is 0.6 W. The dark room contrast of 1∶100 is achieved without using a polarization filter.

We experimentally demonstrate mode-division multiplexed(MDM)transmission using eight orbital angular momentum(OAM)modes over a single span of 100-km low-attenuation and low-crosstalk ring-core fiber(RCF).Each OAM mode channel carries 10 wavelength-division multiplexing(WDM)signal channels in the C band,with each WDM channel in turn transmitting 16-GBaud quadrature phase-shift keying signal.An aggregate capacity of 2.56 Tbit/s and an overall spectral efficiency of 10.24 bit/(s·Hz)are realized.The capacity-distance product of 256(Tbit/s)·km is the largest reported so far for OAM fiber communications systems to the best of our knowledge.Exploiting the low crosstalk between the OAM mode groups in the RCF,the scheme only requires the use of modular 4×4 multiple-input multiple-output processing,and it can therefore be scaled up in the number of MDM channels without increasing the complexity of signal processing.

Hepatocellular carcinoma(HCC) is one of the most lethal malignancies in the world. Several signaling pathways,including the wingless/int-1(Wnt) signaling pathway,have been shown to be commonly activated in HCC. The Wnt signaling pathway can be triggered via both catenin β1(CTNNB1)-dependent(also known as "canonical") and CTNNB1-independent(often referred to as "non-canonical") pathways. Specifically,the canonical Wnt pathway is one of those most frequently reported in HCC. Aberrant regulation from three complexes(the cell-surface receptor complex,the cytoplasmic destruction complex and the nuclear CTNNB1/T-cell-specific transcription factor/lymphoid enhancer binding factor transcriptional complex) are all involved in HCC. Although the non-canonical Wnt pathway is rarely reported,two main non-canonical pathways,Wnt/planar cell polarity pathway and Wnt/Ca2+ pathway,participate in the regulation of hepatocarcinogenesis. Interestingly,the canonical Wnt pathway is antagonized by non-canonical Wnt signaling in HCC. Moreover,other signaling cascades have also been demonstrated to regulate the Wnt pathway through crosstalk in HCC pathogenesis. This review provides a perspective on the emerging evidence that the aberrant regulation of Wnt signaling is a critical mechanism for the development of HCC. Furthermore,crosstalk between different signaling pathways might be conducive to the development of novel molecular targets of HCC.

研究目的:"运动是良医"这一理念由美国运动医学会于2007年正式提出,并在全球范围内得到认可。但运动是如何改善健康,其中具体机制尚未完全清楚。先前的研究发现肌肉与骨骼是单纯的机械性耦连关系即肌肉提供载荷而骨提供附着点,临床研究也证实缺少肌肉载荷的骨的密度和机械性能也都出现显著性下降。但近几年的研究发现肌肉和骨骼可以作为内分泌器官来分泌相关的因子从而相互影响,由肌纤维分泌出的肌肉因子如Myostatin、IL-6、IGF-1、FGF-2等细胞因子通过发挥自分泌、旁分泌和内分泌作用来影响骨代谢,骨分泌的相关因子如Osteocalcin、FGF23、PGE2、Wnt-3a也在一定程度上影响肌组织的代谢和功能,即肌肉和骨骼不仅存在机械上的耦连关系,也存在生理上的耦连。其中骨组织通过骨吸收和骨形成这一过程进行不断的进行自我更新,由破骨细胞主导骨的吸收过程,成骨细胞主导骨的形成过程。骨再生与骨吸收之间的不平衡所导致的骨代谢失衡是许多骨病发病的基础。目前对于骨相关疾病治疗手段大多集中药物与手术治疗,相比于这两种治疗手段,运动疗法具有成本低、副作用小和参与程度高等特点。因此本研究通过离体实验,从肌骨"crosstalk"的角度出发来观察机械应力刺激对成肌诱导分化后的成肌细胞的相关成骨因子表达的影响,从而探究利用肌肉因子来改善和调控骨代谢,为运动改善骨骼健康提供更多的理论据。研究方法:(1)成肌细胞成肌诱导分化实验:复苏冻存C2C12细胞系,用Dulbecco’s modified Eagle medium(DMEM)培养基(10%胎牛血清)培养至细胞密度90%以上进行传代,传至第3代后接种于6孔细胞培养板中,在培养液中加入成肌诱导分化剂DMEM(2%马血清、1%青霉素和链霉素),将C2C12细胞系在成肌分化诱导剂的作用下培养2天,诱导分化结束后观察细胞状态进行牵拉。(2)机械牵张成肌细胞实验:在进行成肌诱导分化后采用Flexcell-5000细胞应力加载系统对小鼠C2C12成肌细胞系进行机械牵张干预,采用10%牵张强度,0.125Hz,单次刺激时间为4小时的牵张方案对成肌细胞进行为期2、4天的牵张刺激,牵张结束后提取各组RNA,逆转录后使用荧光定量PCR检测相关成骨因子的表达:OSX(Osterix)、Runx2(runt-related transcription factor 2)。(3)所有实验结果用均数±标准差(x±SD)表示,使用SPSS 22.0软件对实验数据进行分析处理,主要采用的统计学方法为组内比较使用配对样本T检验,组间样本比较使用独立样本T检验,以Pcrosstalk"的角度为运动改善骨健康提供了更多的理论依据。

Periodic Modulation of Nonlinearity in a Two-Core Photonic Crystal Fiber: A Numerical Investigation

＜正＞A new method is presented to suppress the cross-talk of high speed digital circuits,when the rise time and fall time of transmitted signal are shorter than 500ps.The proposed method is to use alternative smoothly changing phase-velocity microstrip lines （Alter-P lines） on printed circuit board.A pair of Alter-p lines are composed of a homogeneous line and a period structured slow-wave line,which makes the phase velocity difference between neighboring tracks. Preliminary theoretical analysis,with the quasi-TEM and no lost approximation,proves the cross-talk between tracks can be controlled by the phase constant difference of the tracks.Simulation and experiment have shown that the cross-talk is lower than conventional parallel microstrip lines.

We present a numerical investigation of the propagation and the switching of ultra-short pulses (100 fs) in a two-core nonlinear coupler of photonic crystal fibers constructed with periodically modulated the non-linearity fiber (PMNL-PFC). Our simulations are taking into account different amplitude and frequency modulations of the PMNL-PFC. A coupler for coupling whose length is Lc = 1.8 cm, the transmission characteristics, the compression factor, the crosstalk (Xtalk) and extinction ratio (Xratio) levels of the first order solitons were studied for low to high pump energies considering 2Lc. By an analysis on the reference channel (channel 2), it is observed that at low modulation frequencies an increase occurs in the switching power increasing transmission efficiency. For high modulation frequencies, the transmitted energy efficiency loses. The switching pulses are stronger for low frequency and high amplitude modulation. The Xtalk is a function of the measurement made on the secondary channel (channel 1). It was observed that this unwanted high-frequency energy increases to lessen the measure of the amplitude modulation. In summary, we have demonstrated that introduction of a non-linearity profile takes the periodically modulated PMNL-PFC to strong variations at transmission efficiency, Xtalk, Xratio a function of frequency and modulation amplitude and the input power.
