Stephanie Forsythe和todd Macallen，二人相识于建筑，却相信小型的，可触摸的物体对切身的空间感受有着更为真实而强烈的影响。认为家具的设计过程提高了他们建筑设计时对人体尺度和切身感受的认知。相反的，家具产品的设计也得益于他们建筑设计时对大环境的考量和空间的塑造。在这种碰撞中，不断地去探索艺术、建筑和设计的重叠领域，醉心于空间的创造及材料、结构的创新，于是molo诞生了。

使用点探测视觉任务和融入真实疼痛刺激的视觉任务,以疼痛-中性、中性-中性图片为实验材料,采用眼动追踪技术,测量慢性疼痛患者对疼痛线索的动态注视偏向指标,并进一步考察这些指标对6个月后慢性疼痛强度和功能损伤变化的预测作用。研究发现,点探测视觉任务中,慢性疼痛患者在前3个时间窗上(0~500 ms、500~1000 ms、1000~1500 ms)对疼痛线索的注视偏向显著高于对中性线索的注视偏向,但在第四个时间窗上(1500~2000ms)不存在差异;融入真实疼痛刺激的视觉任务中,慢性疼痛患者在4个时间窗上对疼痛线索的注视偏向均显著高于对中性线索的注视偏向。分层标准多元回归模型和机器学习回归模型均发现,慢性疼痛患者在两个任务中对疼痛线索的晚期注视偏向(1000~1500ms、1500~2000ms两个时间窗),均可以独立预测6个月后慢性疼痛强度和功能损伤的维持。研究结果表明,尽管慢性疼痛患者对疼痛线索从注意早期就表现出注视偏向,但是只有晚期的注视偏向能够预测慢性疼痛的维持。

Background: Premature cervical softening and shortening may be considered an early mechanical failure that predispose to preterm birth. Purpose: This study aims to explore the applicability of an innovative cervical tactile ultrasound approach for predicting spontaneous preterm birth (sPTB). Materials and Methods: Eligible participants were women with low-risk singleton pregnancies in their second trimester, enrolled in this prospective observational study. A Cervix Monitor (CM) device was designed with a vaginal probe comprising four tactile sensors and a single ultrasound transducer operating at 5 MHz. The probe enabled the application of controllable pressure to the external cervical surface, facilitating the acquisition of stress-strain data from both anterior and posterior cervical sectors. Gestational age at delivery was recorded and compared against cervical elasticity. Results: CM examination data were analyzed for 127 women at 240/7 - 286/7 gestational weeks. sPTB was observed in 6.3% of the cases. The preterm group exhibited a lower average cervical stress-to-strain ratio (elasticity) of 0.70 ± 0.26 kPa/mm compared to the term group’s 1.63 ± 0.65 kPa/mm with a p-value of 1.1 × 10−4. Diagnostic accuracy for predicting spontaneous preterm birth based solely on cervical elasticity data was found to be 95.0% (95% CI, 88.5 - 100.0). Conclusion: These findings suggest that measuring cervical elasticity with the designed tactile ultrasound probe has the potential to predict spontaneous preterm birth in a cost-effective manner.

青藏高原及其周缘褶皱-冲断带变形方式和时限是验证高原形成众多大陆岩石圈变形动力学端员模型的关键。近年发展起来的断层泥自生伊利石K-Ar定年技术为精确限定褶皱-冲断带变形时限提供了有效手段。鲜水河—安宁河—小江断裂系作为伴随印度-欧亚板块碰撞造山和高原物质侧向挤出过程形成的大型左旋走滑断裂系,其变形过程可为解译印度-欧亚板块碰撞远程应力向东传递方式提供关键证据。本文选取安宁河断裂冕宁—西昌段作为研究对象,在详细构造解析以明确其构造运动学特征的基础上,开展了断层泥自生伊利石K-Ar定年研究,以期精确限定安宁河断裂脆性变形的时间。构造解析表明安宁河断裂在近EW向挤压作用下经历了冲断变形,断层带发育碎斑岩和断层泥,指示为脆性变形。安宁河断裂不同粒级断层泥样品的黏土矿物学和伊利石K-Ar定年分析揭示,随着样品粒级减小,高温2M1型伊利石含量相对低温1M/1Md型伊利石含量逐渐减少,其K-Ar年龄总体呈变年轻趋势,表明不同粒级伊利石K-Ar年龄是由碎屑2M1型和自生1M/1Md型两个多型端员组成的混合年龄。伊利石年龄分析获得自生1M/1Md型伊利石的年龄为(42.6±9.4)Ma,表明安宁河断裂经历了始新世中期的冲断变形。结合前人构造变形、沉积学、低温热年代学和古地磁等研究,我们认为始新世中期青藏高原腹地及其周缘褶皱-冲断带发生准同期的构造挤压变形,其动力学机制可能与印度-欧亚板块硬碰撞以及青藏高原地块的陆内俯冲所导致的先存构造带活化有关。始新世中期安宁河断裂发生冲断变形直接证明印度-欧亚板块碰撞初期的远程应力已传递至青藏高原东南缘地区。
