    • The invention includes a method of dehydration of a sugar using a dehydration catalyst and a co-catalyst within a reactor. A sugar is introduced and H 2 is flowed through the reactor at a pressure of less than or equal to about 300 psig to convert at least some of the sugar into an anhydrosugar product. The invention includes a process for producing isosorbide. A starting material comprising sorbitol is flowed into a reactor. H 2 is counter flowed through the reactor. The starting material is exposed to a catalyst in the presence of a co- catalyst which comprises at least one metal. The exposing is conducted at a hydrogen pressure of less than or equal to 300 psig within the reactor and the hydrogen removes at least some of any water present during the exposing and inhibits formation of colored byproducts.

    • The invention provides a virtual assembly design environment (VAE) that can simulate axial and planar constrained motion for multiple parts in any combination and application order. Each sequence of assembly operations can be recorded and stored for later usage. A guidance mechanism may be employed by a user to assist in performing the assembly operations. Dynamic simulation methods may be used to simulate object behavior in the VAE using physical laws and collision detection algorithms. The physical properties of the parts can be created in a separate CAD system (including mass properties). In the invention, physical property information is transferred from the CAD system to a virtual reality environment where it is used in dynamic simulations. The parts behave realistically in the user's hand, constrained on the base part, or moving freely in space. A swept volume can be generated directly in the CAD system which is more accurate and compact than those created using numerical methods and can be easily processed by CAD systems. A swept volume trajectory editing mechanism has been implemented. Real time bi-directional data transfer between the VR environment and the CAD system has been achieved. The user can perform parametric design modifications in the virtual environment through a CAD system.
    • 本发明提供了一种虚拟装配设计环境(VAE),其可以以任何组合和应用顺序模拟多个部件的轴向和平面约束运动。 装配操作的每个顺序都可以被记录并存储以供以后使用。 用户可以使用指导机制来辅助执行组装操作。 动态仿真方法可用于使用物理定律和碰撞检测算法来模拟VAE中的对象行为。 零件的物理属性可以在单独的CAD系统中创建(包括质量属性)。 在本发明中,物理属性信息从CAD系统转移到虚拟现实环境中,在虚拟现实环境中用于动态模拟。 这些部件在用户的手中表现得真实,限制在底座部分上,或者在空间中自由移动。 扫描体积可以直接在CAD系统中生成,比使用数值方法创建的更精确和更紧凑,并且可以通过CAD系统轻松处理。 扫描音量轨迹编辑机制已经实施。 VR环境和CAD系统之间的实时双向数据传输已经实现。 用户可以通过CAD系统在虚拟环境中执行参数化设计修改。

    • The present invention relates to novel porous matrix composites and formulations for controlled protein delivery and the uses therefor. The present invention also provides methods of synthesizing such protein delivery systems. The composites comprise affinity sites embedded in the matrix where the affinity sites are functionalized with nucleic acid aptamers having high affinity for proteins to be released. The aptamers function as binding affinity sites for the proteins to be released. In certain embodiments, release rates are controlled by tuning the binding affinity of the nucleic acid aptamerd to the proteins at a desired level. In yet other embodiments, complementary oligonucleotides that hybridize with the aptamerd are employed to trigger accelerated release of the proteins when desired. Various in situ injectable hydro gels functionalized with aptamers are provided for treating a condition and disease in a subject in need of a therapeutic protein.
