Title: System and method for scoring test answer sheets having open-ended questions
Inventor: KUCINSKI BERNARD
IPC: G06Q30/02
Filed: 1998-07-13
Abstract: A scoring system and method include a distribution application for delivering an answer image to a qualified reader. The distributor prefetches a batch of answer images from long-term storage and caches them for retrieval and scoring. The scoring process includes displaying an answer based upon an answer image form along with a scoring protocol. Geometric tools are also available for assisting in scoring geometry tests. A routing system permits a reader to electronically pose a query to a supervisor and to continue working on another answer while the query is being addressed. A reader's effectiveness and efficiency can be monitored by distributing a calibration answer to the reader in transparent fashion and comparing the resulting score with a target score.

Title: Network based tariff acquisition system for roaming mobile subscribers
Inventor: RAHMAN TARIQ
IPC: H04M15/00
Filed: 1998-09-22
Abstract: A method of obtaining tariff rates on a plurality of candidate service providers accessible to a roaming mobile subscriber for use in choosing the most suitable candidate service provider in a visited area. The method includes initiating registration by the mobile subscriber to a first candidate service provider. A request for subscriber's profile information is made by the first candidate service provider to the subscriber's home service provider. Additionally, the first candidate service provider sends the intended tariff rate to be charged to the subscriber to the home provider. The home provider determines which other candidate providers are accessible by the subscriber and requests tariff information regarding these providers. The home provider may then determine the most suitable provider based on the received tariff information e.g. the lowest tariff. If the provider of the currently pending registration is determined to be the most suitable, the registration process continues and the subscriber remains registered with the first candidate service provider. If on the other hand a second candidate service provider is most suitable, the home provider notifies the subscriber of this information via an SMS message, for example. The subscriber can then register with the appropriate provider either manually or automatically in response to the notification.

Title: A role for the tat protein of hiv-1 in suppression of viral reverse transcriptase activity during late stages of viral replication
Inventor: WAINBERG MARK A
IPC: C12Q1/70
Filed: 2001-02-22
Abstract: We have examined the role of the human immunodeficiency virus type-1 (H1V-1) Tat protein in the regulation of reverse transcription. We show that a 2 exon- but not a 1-exon-form of Tat markedly suppressed cell-free reverse transcriptase (RT) activity.      Conversely, viruses expressing 2-exon-Tat (pNL43 and pNL101) showed rapid replication kinetics and more efficient endogenous RT activity compared with viruses expressing 1-exon Tat (pM1ex). The pM1ex virions as well as pM1ex-infected cells also contained higher levels of viral DNA than did either the pNL43 or pNL101 viruses, indicating that reverse transcription might have continued during later stages of viral replication in the absence of the second Tat exon. Moreover, degradation of viral genomic RNA was more apparent in the pM1ex virions. Accordingly, we propose that 2 exon Tat may help augment viral infectivity by suppressing the reverse transcription reaction during late stages of viral synthesis and by preventing the synthesis of potentially deleterious viral DNA products.~

Title: Channel allocation in a telecommunications system with asymmetric uplink and downlink traffic
Inventor: KRONESTEDT FREDRIC
IPC: H04W72/08
Filed: 1999-06-24
Abstract: In a synchronous cellular radio telecommunications network that employs a ti me division multiple access (TDMA) channel allocation scheme, an effective approach to allocating channels or time slots in a TDMA time frame containin g asymmetric downlink and uplink traffic channel fields can be achieved by dividing the downlink and uplink traffic channel fields into a number of regions, based on an expected level of intercell interference associated wit h each region. In addition, the level of susceptibility to intercell interference for each mobile unit operating in a given cell is continuously established. The allocation of channels or time slots is then carried out fo r each of the mobile units based on, among other things, the level of susceptibility associated with each of the mobile units, the level of expect ed intercell interference associated with each of the regions, and whether the channel or time slot is being allocated for the purpose of conveying information in the uplink or downlink traffic channel field.

Patent CA-2341519-A1 (CA)
Title: Gels and multilayer surface structures from boronic acid containing polymers
Inventor: HUBBELL JEFFREY A
IPC: A61K9/48
Filed: 1999-08-27
Abstract: Boronic acid containing polymers are used to form bioinert gels and multilayer surface structures. These polymers form cross-linked hydrogels, which are highly swollen in water. The cross-linking can either be chemical or physical. Water soluble polymers containing boronic acid groups, such as phenylboronic acid (PBA), can be physically cross-linked by mixing the polymers in water with other polymers containing hydroxyls or carboxylic acids. Alternatively, surfaces can be treated by stepwise incubation with a solution of the boronic acid containing polymer, followed by incubation with a solution of a diol or carboxylic acid containing polymer. Many successive layers can be generated, increasing the thickness of the formed structure at each step.  The bioinert gel or surface coating can be used for passivating the surfaces of medical implants (especially those based on transplanted tissue), or for passivating the surfaces of tissues in situ, decreasing the incidence or severity of such pathologic conditions as the formation of post-surgical adhesions, and thrombosis following angioplasty.
