Abstract: A method and processor for classifying documents are provided. Using a classification model with classifiers, items are classified into classes. The method includes acquiring a model for classification, creating a training dataset with items and class labels, and training a new classifier for an additional class not in the original set. This results in a modified model that includes both the original classifiers and the new classifier, allowing for classification into an expanded set of classes. The method involves generating a training dataset, training a new classifier, modifying the classification model, and determining a predicted class for items, including the new class.

Abstract: A method and an electronic device for generating an anonymized audio output are provided. The method, executable by the electronic device, comprises acquiring an audio recording of a speaker; stochastically determining a base pitch value based on at least a first probabilistic function; segmenting the original audio input into a plurality of audio segments, each of the plurality of audio segments being associated with a respective pitch. For each audio segment, the method further comprises generating a pitch adjustment value using a combination of the base pitch value of the segment and a value determined using a second probabilistic function; generating an adjusted audio segment by adjusting the pitch of the audio segment using the pitch adjustment value, the adjusted audio segment having an adjusted pitch that is different from the original pitch; generating the anonymized audio output by combining the adjusted audio segments.

Abstract: Web conferencing is enhanced with conversation groups having individual group volume controls. Multiple conversations are perceived by participants, the conversations having varied microphone volume levels that allows a participant to engage in one conversation group while, at the same time, listening in on other simultaneous conversations having a relatively lower volume setting. A user interface provides for user-selection of conversation groups in which to participate. Group conversations are established according to conditional rules related to number of participants and time lapse between mentions of a particular topic and/or multiple comments by a one participant responsive to another participant.

Abstract: Use of phosphorus-based material in preparation of medicament for treating tumors. The phosphorus-based material is selected from a material which is convertible to produce phosphate ions in an acidic environment, and the phosphorus-based material can be converted by tumor cells phagocytosis to produce a large number of phosphate ions to change the intraceullar environment and extracellular environment, thereby inhibiting proliferation of tumor cells and inducing death of tumor cells. This process has no significant effect on normal cell activities. By applying the phosphorus-based material to the preparation of a medicament for treating tumor in a manner as mentioned above, the amplification and metastasis of tumor cells can be effectively inhibited, thereby the metastasis of the tumor cells and recurrence of the tumor can be prevented more effectively, improving the therapeutic effect of the tumor. The phosphorus-based material has little effect on normal cells and tissues in the course of treatment.
