摘要： Disclosed is a monolithic integrated circuit (IC) computing device with multiple independent process cores (multicore) and embedded, non-volatile resistive memory serving as system memory. The resistive system memory is fabricated above the substrate, and logic circuits embodying the process cores are fabricated on the substrate. In addition, access circuitry for operating on the resistive system memory, and circuitry embodying memory controllers, routing devices and other logic components is provided at least in part on the substrate. Large main memory capacities of tens or hundreds of gigabytes (GB) are provided and operable with many process cores, all on a single die. This monolithic integration provides close physical proximity between the process cores and main memory, facilitating significant memory parallelism, reduced power consumption, and eliminating off-chip main memory access requests.

摘要： Wood fibers possess natural unique hierarchical and mesoporous structures that enable a variety of new applications beyond their traditional use. For the first time we dramatically modulate the propagation of light through random network of wood fibers. A highly transparent and clear paper with transmittance >90% and haze 90% and haze >90% is also achieved. A thorough investigation of the relation between the mesoporous structure and the optical properties in transparent paper was conducted, including full-spectrum optical simulations. We demonstrate commercially competitive multi-touch touchscreen with clear paper as a replacement for plastic substrates, which shows excellent process compatibility and comparable device performance for commercial applications. Transparent cellulose paper with tunable optical properties is an emerging photonic material that will realize a range of much improved flexible electronics, photonics and optoelectronics.

摘要： A method and apparatus for monitoring arterial properties, including systolic and diastolic pressure levels, of a subject is provided, in which a hardware processor receives and analyzes ballistocardiogram (BCG) data of the subject. A non-transient computer readable medium, accessible by the hardware processor, contains instructions that, when executed by the hardware processor, identify features of the BCG waveform and determine the arterial properties therefrom. For example, a diastolic pressure level may be determined from a time interval between the ‘I’ and ‘J’ peaks of the waveform and a systolic pressure level determined from the amplitude difference between the ‘J’ and ‘K’ peaks of the waveform in combination with the ‘I-J’ time interval or amplitude difference. A physical mechanism for the BCG data is disclosed that enables other arterial properties of the subject to be determined from the BCG data alone or from the BCG data in combination with other measurements.

摘要： Solar cell substrates require high optical transparency, but also prefer high optical haze to increase the light scattering and consequently the absorption in the active materials. Unfortunately there is a tradeoff between these optical properties, which is exemplified by common transparent paper substrates exhibiting a transparency of about 90% yet a low optical haze (
摘要翻译：太阳能电池基板需要高的光学透明度，而且还优选高的光学雾度以增加光散射并因此增加活性材料的吸收。不幸的是，在这些光学性质之间存在折衷，其通过透明度为约90％但光学雾度低（<20％）的普通透明纸基材为例。在这项工作中，我们引进了一种新型的木纤维透明纸，显示了超高光学透明度（〜96％）和超高雾度（〜60％），从而为太阳能电池设备提供了最佳的基板设计。与先前证明的由木质纤维素纳米纤维组成的纳米纤维相比，我们的新型透明纸在透光率和雾度方面具有更好的双重性能，而且以低得多的成本制造。这种高性能，低成本的透明纸是潜在的革命性材料，可能会影响新一代环保印刷电子产品。

摘要： The present application is drawn to a synthetic, polymer hydrogel-based material, which is able to actively induce the body's natural hemostatic coagulation process in blood or acellular plasma. The present invention provides the development of a primary amine containing polymer hydrogel capable of inducing blood coagulation and delivering therapeutics for hemostatic or wound care applications, and a method of forming such a primary amine containing polymer hydrogel capable of inducing the blood coagulation process. The primary amine containing polymer hydrogel is able to achieve the same end result as biological-based hemostatics, without the innate risk of disease transmission or immunological response, and at a fraction of the price. Furthermore, due to its inherent hydrogel-based design the material has the capability of arresting blood loss while simultaneously delivering therapeutics in a controlled manner, potentially revolutionizing the way in which wounds are treated.
