BACKGROUND The Parent-Infant Relationship Global Assessment Scale (PIR-GAS) signifies a conceptually relevant development in the multi-axial, developmentally sensitive classification system DC:0-3R for preschool children. However, information about the reliability and validity of the PIR-GAS is rare. A review of the available empirical studies suggests that in research, PIR-GAS ratings can be b...

The retrieval of information from a remote database server typically demands providing the server with some search terms to assist with the retrieval task. However, keeping the search terms private without undermining the server’s ability to retrieve the desired information is a common requirement for many privacy-preservingsystems. Private information retrieval (PIR) provides a cryptographicme...

Private information retrieval (PIR) is normally modeled as a game between two players: a user and a database. The user wants to retrieve some item from the database without the latter learning which item is retrieved. Most current PIR protocols are ill-suited to provide PIR from a search engine or large database: (i) their computational complexity is linear in the size of the database; (ii) the...

A series of Oligocene through Early Miocene terrestrial deposits preserved in the foothills of the Zinda Pir Dome of western Pakistan produce multiple, superposed fossil mammal localities. These include small mammal assemblages that shed light on the evolution of rodent lineages, especially Muroidea, in South Asia. Nine small mammal localities span approximately 28-19 Ma, an interval encompassi...

This work demonstrates the feasibility of building a PIR system with performance similar to non-PIR systems in real situations. Prior Chor PIR systems have chosen block sizes that are theoretically optimized to minimize communication. This (ironically) reduces the throughput of the resulting system by roughly 50x. We constructed a Chor PIR system called upPIR that is efficient by choosing block...

Allergy is caused by immune effector cells, including mast cells and basophils. Cellular signaling that activates these effector cells is regulated by different inhibitory receptors on their surface. We show that human leukocyte immunoglobulin (Ig)-like receptor (LILR) B2 and its mouse orthologue, paired Ig-like receptor (PIR)-B, constitutively associate to major histocompatibility complex (MHC...

Sensitization of C57BL/6 (B6, H-2b) splenocytes against normal BALB/c (H-2d) leukocytes (B6 a/BALB) in bulk MLC induced CTL reactive against the syngeneic (H-2b) nonimmunogenic lymphoma PIR-2, in addition to the CTL directed against the corresponding (H-2d) allotargets. However, MLC-derived lymphocytes did not directly exhibit anti-PIR-2 cytotoxicity in spite of the high anti-PIR-2 CTL frequenc...

In recent years, the subject of online privacy has been attracting much interest, especially as more Internet users than ever are beginning to care about the privacy of their online activities. Privacy concerns are even prompting legislators in some countries to demand from service providers a more privacy-friendly Internet experience for their citizens. These are welcomed developments and in s...

A Private Information Retrieval (PIR) scheme is a protocol in which a user retrieves a record out of N from a replicated database, while hiding from the database which record has been retrieved, as long as the different replicas do not collude. A specially interesting sub-field of research, called singledatabase PIR, deals with the schemes that allow a user to retrieve privately an element of a...
