B6.KI mice were immunized with spleen cells from B6.K2, a Qa2-subregion congenic strain. Cytotoxic T cells were generated that recognize two target antigens controlled by this region. One of the target antigens is Qa-2. This was demonstrated by the findings that pretreatment of target cells with monoclonal anti-Qa-2 antibody blocked lysis of target cells, and Qa-2 target antigens and serologica...

While question answering (QA) with neural network, i.e. neural QA, has achieved promising results in recent years, lacking of large scale real-word QA dataset is still a challenge for developing and evaluating neural QA system. To alleviate this problem, we propose a large scale human annotated real-world QA dataset WebQA with more than 42k questions and 556k evidences. As existing neural QA me...

The unprecedented volume of information on the Web brings the practical difficulties for the information consumers to assess the quality of information. The wide variety of web users and distinct situations at their hands pose the difficulties to the quality assessment (QA) process, which must be customizable according to the information consumer’s needs. To that end, we (1) introduce the Web Q...

In this paper, the results of two industrial case studies on software project management are presented. These case studies revealed key problem areas in software project management and also proved that there is a serious lack in training of software project managers. To reduce these deficiencies, we suggest a new approach for teaching project management: simulating software projects. The simula...

objective: the cerebellum is a key structure involved in coordinated motor planning, cognition, learning and memory functions. this study presents a permanent model of a toxin produced cerebellar lesion characterized according to contemporary motor and cognitive abnormalities. materials and methods: in this experimental study, slow administration of quinolinic acid (qa, 5 μl of 200 μmol, 1 μl/m...

We previously reported important differences in resistance to Taenia crassiceps murine cysticercosis between BALB/c substrains. It was suggested that resistance might correlate with expression of the nonclassic class I major histocompatibility complex (MHC) Qa-2 antigen; BALB/cAnN is Qa-2 negative and highly susceptible to T. crassiceps, whereas BALB/cJ expresses Qa-2 and is highly resistant. I...

BACKGROUND AND OBJECTIVES Measurement of blood flow rate (Qa) is used to monitor dialysis access, AV fistulas, and grafts. Indicator dilution measurements of the recirculation (R) induced by reversal of hemodialysis blood lines are commonly used. This plus the dialysis circuit flow (Qb) allows calculation of Qa. R also changes the conductivity, which can be measured by a conductivity cell in th...

Recent biochemical characterization of the T23-encoded Qa-1 molecule revealed an additional higher molecular mass species of 50 kD coprecipitated with the 48-kD Qa-1 molecule in H-2b and H-2d mouse strains. We now demonstrate that the 50-kD protein coprecipitated with Qa-1 is the class I-a antigen Ld in all H-2Ld-positive mouse strains examined. Furthers analyses of a panel of recombinants reve...

AbstractTable Question Answering (Table QA) refers to providing precise answers from tables answer a user’s question. In recent years, there have been lot of works on table QA, but is lack comprehensive surveys this research topic. Hence, we aim provide an overview available datasets and representative methods in QA. We classify existing for QA into five categories according their techniques, w...

Quaternary ammonium (QA) blockers are well-known structural probes for studying the permeation pathway of voltage-gated K+ channels. In this study we have examined the effects of a series of n-alkyl-trimethylammonium compounds (Cn-QA) on batrachotoxin (BTX)-activated Na+ channels from skeletal muscle incorporated into planar lipid bilayers. We found that these amphipathic QA compounds (Cn-QA wh...
