Routing in a peer-to-peer network is described. In an implementation, a method includes receiving at one of a plurality of nodes in a peer-to-peer network, an indication of a change in membership in the peer-to-peer network by another node in the peer-to-peer network. A report is broadcast that describes the change. The report is for receipt by each node referenced in a routing table included in the one node.

Disposable units in current use for performing PCR are limited by their heat block ramping rates and by the thermal diffusion delay time through the plastic wall as well as by the sample itself. This limitation has been overcome by forming a disposable plastic chip using a simple deformation process wherein one or more plastic sheets are caused, through hydrostatic pressure, to conform to the surface of a suitable mold. After a given disposable chip has been filled with liquid samples, it is brought into close contact with an array of heating blocks that seals each sample within its own chamber, allowing each sample to then be heat treated as desired.

The invention provides methods of treating neoplasia using combinations of target cell-specific replication competent adenoviral vectors and chemotherapy, radiation therapy or combinations thereof. The adenoviral vectors are target cell-specific for the particular type of neoplasia for which treatment is necessary and the combination with the chemotherapy and/or radiation leads to synergistic treatment over existing adenoviral therapy or traditional chemotherapy and radiation therapy.

A concentrated solar energy system includes a photovoltaic cell, an optical concentrator, a heat removal system, and means for providing thermal contact between the photovoltaic cell and the heat removal system. The optical concentrator is configured to direct concentrated solar energy to the photovoltaic cell such that the photovoltaic cell generates electricity and heat. The heat removal system removes heat from the photovoltaic cell. The means for providing thermal contact provides an effective thermal conductivity per unit length between the photovoltaic cell and the heat removal system of greater than about 50 kilowatts per square meter per degree Celsius.

An integrated optical auto focus and zooming system is provided, which includes a first optical lens, a first hollow casing, a second hollow casing, a plurality of piezoelectric elements. The first optical lens is placed in the first hollow casing, the first hollow casing and the second hollow casing are screwed with each other, and the plurality of piezoelectric elements are attached either on the first hollow casing or the second hollow casing. Upon the excitation of mechanical vibrations by the plurality of piezoelectric elements, a traveling wave is generated on the attached casing, so as to drive the other casing to rotate and then to move axially. Additional lens groups and casings can be added in the same way so to achieve multiple relative motions between lens groups and image sensor, and thus achieving the objectives of focusing and zooming. The present invention integrates the motor into the lens and hence eliminates the transmission mechanism, leading to simple structure, high efficiency, and multiple advantages in size, cost, and efficiency, etc., and thus can be very useful.
摘要:
A heat pump, and in particular a heat pump for heating a hot water supply is provided with an improved defrost mode. The defrost mode is actuated to remove frost from an outdoor evaporator that may accumulate during cold weather operation. An algorithm for operation of the defrost mode is developed experimentally by seeking to maximize the heat transfer provided by the refrigerant. A heating system condition is experimentally related to the heat transfer capacity. One then maximizes the average heat transfer capacity to determine the optimum initiation point for the defrost mode. Further, protections are included into the defrost mode. When the heat pump is utilized to heat hot water, methods are provided to prevent the water that remains in the heat exchanger from becoming unduly heated. In one method, the water pump may be periodically operated to move the water. In a second method, a control ensures the discharge pressure of the refrigerant leaving the compressor is reduced, and that the water pump is not stopped until that reduced temperature falls below a predetermined maximum. The temperature reduction is achieved through a dual control loop wherein a temperature that is too high results in a new desired discharge pressure. The control achieves the new desired pressure by controlling the expansion device. In another protection feature, as a control determines that the defrost mode is nearing its end, an evaporator fan is run to remove melted water from the evaporator coils, and also to ensure the refrigerant leaving the evaporator does not reach unduly high pressure or temperatures.
