Abstract: A method of repelling an insect pest such as a tick, mosquito or cockroach comprises applying to a subject or substrate, in an amount effect to repel the insect pest, a compound of Formula I: wherein R is C4-C20 linear or branched alkyl. Particularly preferred compounds of Formula (I) are 2-tridecanone and 2-undecanone.

Abstract: An electrochemical detection system which specifically detects selected nucleic acid segments is described. The system utilizes biological probes such as nucleic acid or peptide nucleic acid probes which are complementary to and specifically hybridize with selected nucleic acid segments in order to generate a measurable current when an amperometric potential is applied. The electrochemical signal can be quantified.

Abstract: The present invention provides non-peptide organic compounds that have a structure analogous to or reminiscent of the TMOF structure and have pesticidal activity. Thus the present invention concerns pesticidal compounds that inhibit digestion in pests by terminating or otherwise blocking synthesis of digestive enzymes by activating a TMOF receptor (collectively referred to herein as “pesticidal compounds”). The pesticidal compounds and other compounds of the present invention are usefully employed in the control of pests, particularly insect pests Such as mosquitoes, which ingest blood.

Abstract: Insecticidal compounds comprising an insecticidal peptide (e.g., juvenile hormone esters) or nucleic acid (e.g. Ea baculovirus) or insecticide covalently conjugated to a polymer are described. Methods of use thereof for controlling insects and compositions containing the same are also described.

Abstract: A flexible, intelligent electronic procurement method and system that emulates and learns from the adaptive behavior of a user trying to find a product in an electronic catalog. In contrast to existing methods and systems, the invention does not require the pre-loading of index hierarchies, it does not impose fixed structures on the user, it does not require the user to start ‘from scratch’ when looking for a new item, and it does not force the user to think like someone else. Instead, the invention allows the user to choose his own way to navigate catalogs of items, and then, by remembering successful search scenarios, and storing that knowledge in a dynamic, growing database (or ‘forest’) of collected search paths, or ‘trees’, the invention evolves ‘organically’ over time. Thus, the utility of the invention increases over time once implemented in a given environment.

Abstract: Methods of assaying insects for pesticide resistance and to identify insect species are based on feeding disruption caused by insecticide such as the biopesticide Bacillius thuringiensis toxin (Bt). Further provided are methods for monitoring insecticide resistance in a population of insects, as well as methods of screening compounds for insecticidal activity. Insecticide resistance can be assessed at the level of an individual insect or at population levels. Apparatus and dehydrated insect meal pads useful in such assays are described.

Abstract: Insecticidal compounds comprising an insecticidal peptide (e.g., Juvenile hormone esterase) or nucleic acid (e.g. a baculovirus) covalently conjugated to a water soluble polymer such as polyethylene glycol are described. Methods of use thereof for controlling insects such as moths, and compositions containing the same are also described.

Abstract: A system and method for authentication verifies the address of an information sender based on the sender's address, public key, and a digital signature. A portion of the sender's address is derived from the public key, such as by incorporating a portion of a hash of the public key with or without a modifier. The sender provides information including content data, the public key, the address, and the digital signature generated using the private key corresponding to the public key. Upon reception, the recipient verifies the address by recreating it from the public key. The signature is verified using the network address and public key. The recipient accepts the content data when both the address and signature are verified. The content data may include a communications parameter of the sender, such as a care-of address where the sender is a mobile device and the recipient is the sender's home agent.

Abstract: Disclosed is an authentication mechanism that enables an information recipient to ascertain that the information comes from the sender it purports to be from. This mechanism integrates a private/public key pair with selection by the sender of a portion of its address. The sender derives its address from its public key, for example, by using a hash of the key. The recipient verifies the association between the address and the sender's private key. The recipient may retrieve the key from an insecure resource and know that it has the correct key because only that key can produce the sender's address in the message. The hash may be made larger than the sender-selectable portion of the address. The recipient may cache public key/address pairs and use the cache to detect brute force attacks and to survive denial of service attacks. The mechanism may be used to optimize security negotiation algorithms.

Abstract: An apparatus and method of copy protection for use in digital data recorders such as DVD-RAM recorders, which includes embedding transmission time information into a digital data stream by digital watermarking and comparing the transmission time with the current time at the data recorder (30, 50). If the time difference is less than a threshold value it is presumed that the recording is for time-shifting purposes, namely recording a programme to watch later, which is generally allowed by copyright laws. If the time difference is greater than a threshold value it is presumed that the recording is an attempted unauthorised recording such as from a pre-recorded copy, and further recording is prevented.

Abstract: Methods of assaying insects for pesticide resistance and to identify insect species are based on feeding disruption caused by pesticides such as the biopesticide Bacillus thuringiensis toxin (Bt). The assay end-point is feeding disruption, measured by the fecal production of insects exposed to a diagnostic dose of pesticide in a test diet. Pesticide resistance can be assessed at the level of an individual insect or at population levels. Apparatus useful in such assays are described.
