Abstract: Disclosed is a system and method for treating and preventing skin disorders. More particularly, the disclosed invention is directed toward the prevention of acne and acne scarring by treating sebaceous oil glands and the surrounding tissue with an exogenous chromophore composition and then exposing the target tissue to visible, infrared, or ultraviolet light to inhibit the activity of the oil gland and eliminate acne bacteria. The method of the present invention may be further augmented by enhancing the penetration of the topical composition into the oil gland and surrounding tissue through the use of procedures including enzyme peeling, microderm abrasion, or ultrasound.

Abstract: Human and mammalian skin undergoes a variety of changes associated with chronological aging. Various environmental factors, disease states and genetic disorders may accelerate both the appearance of aging skin and also the structural and functional changes associated with aging skin. Ultraviolet radiation from the sun is one of the classic known and well-defined means of accelerating or worsening the aging of the skin and this is frequently termed photoaging. Other environmental factors, such as oxidative stress, free radicals, environmental toxins such as ozone and cultural customs or habits such as tobacco smoking are other known probe accelerators in photo aging skin. A wide variety of other factors known and unknown contribute to accelerated or premature aging of the skin. This invention discusses methods where electromagnetic radiation, in particular, light, can be used to photobiomodulate the activity of living cells to delay, diminish, retard or even reverse the structural and functional effects of aging of the skin and other living cells and tissues. In particular methods described for improving the appearance, structure, function of aging skin, including up and down regulating the genotypic markers for the phenotype of aging skin.

Abstract: A mechanism that provides for communication of heartbeat signals from servers (call agents) to clients (gateways) in a packet telephony network environment. Clients listen for receipt of multicast heartbeats from any of the servers that may be part of a multicast group. A client assigned to a particular server for control messaging, upon failure to receive a response to a message sent to the assigned server and failure to receive a heartbeat from the assigned server, may select a second server from among the servers and re-send the message to the second server. Without receipt of heartbeat signals, the client defaults to a normal retry behavior for re-sending the message first to the assigned server a number of times before attempting to re-send the message to the second server. With receipt of the heartbeat from the second server, the client adopts an aggressive retry behavior by re-sending the message to the assigned server a lesser number of retries before attempting to re-send the message to the second server. The clients use the multicast heartbeats as a hint, allowing them to switch to the more aggressive retry behavior and consequently reduce the time to re-associate with a new server and re-establish a new security association (if IPsec is used), resulting in a drastic reduction in service delay due to server failures.

Abstract translation: 一种机制，用于在分组电话网络环境中提供从服务器（呼叫代理）到客户端（网关）的心跳信号的通信。 客户端收听来自任何可能是多播组一部分的服务器的组播心跳信号。 分配给特定服务器以用于控制消息收发的客户端，在未能接收到发送给所分配的服务器的消息的响应以及未能从所分配的服务器接收到心跳的响应时，可以从服务器中选择第二服务器并重新发送 消息到第二台服务器。 在没有收到心跳信号的情况下，客户端默认为正常的重试行为，以便在尝试将消息重新发送到第二个服务器之前先将消息首先发送到分配的服务器。 在从第二台服务器接收到心跳信号之后，客户端在尝试将消息重新发送到第二个服务器之前，通过将消息重新发送到分配的服务器进行较少数量的重试，从而采取积极的重试行为。 客户端使用组播心跳作为提示，允许他们切换到更积极的重试行为，从而减少与新服务器重新关联的时间，并重新建立新的安全关联（如果使用IPsec），导致 由于服务器故障导致的服务延迟急剧减少。

Abstract: The invention is directed to a method and apparatus for timing calibration in a PET scanner. According to one embodiment, the invention relates to a method for timing calibration in a PET scanner having a plurality of scintillator blocks. The method comprises: detecting, in a first scintillator block, a first radiation event, wherein the first scintillator block time-stamps the first radiation event; detecting, in a second scintillator block that is adjacent to the first scintillator block, a second radiation event that corresponds to the first radiation event, wherein the second scintillator block time-stamps the second radiation event; and determining a timing characteristic of the first scintillator block with respect to the second scintillator block based on a comparison between the time-stamps of the first radiation event and the second radiation event.

Abstract: A method for producing preferential damage to hair exiting mammalian skin. A agent having an average diameter for enabling the agent to penetrate the hair duct is selected. The agent is designed to attach to, or become physically incorporated into, the hair shaft, the hair follicle, the hair bulb or the hair duct. The agent has an electromagnetic radiation absorption characteristic which enables the agent to absorb a first wavelength of electromagnetic radiation from a skin-penetrating electromagnetic radiation source, such as a laser. The agent is applied to the skin so that the agent penetrates the skin and attaches to or becomes physically incorporated into the hair shaft, the hair follicle, the hair bulb or the hair duct. The agent is exposed to the first wavelength of electromagnetic radiation and absorbs the first wavelength of electromagnetic radiation.
