Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Bandit-Based Power Control in Full-Duplex Cooperative Relay Networks
No full textFunding Information: ACKNOWLEDGMENT The work of T. Charalambous was supported by the Academy of Finland under Grant 317726. Publisher Copyright: © 2021 IEEE.Full-duplex relaying is an enabling technique of sixth generation (6G) mobile networks, promising tremendous rate and spectral efficiency gains. In order to improve the performance of full-duplex communications, power control is a viable way of avoiding excessive loop interference at the relay. Unfortunately, power control requires channel state information of both source-relay and relay-destination channels, as well as of the loop interference channel, thus resulting in increased overheads. Aiming to offer a low-complexity alternative for power control in full-duplex relay networks, we adopt reward-based learning in the sense of multi-armed bandits. More specifically, we provide bandit-based power control algorithms, relying on acknowledgements/negative-acknowledgements observations by the relay. The proposed algorithms avoid the need for channel state information acquisition and exchange, and can be employed in a distributed manner. Performance evaluation results in terms of outage probability, average throughput and accumulated regret over time highlight an interesting performance-complexity trade-off compared to optimal power control with full channel knowledge and significant performance gains over the cases without power control and random power level selection.Peer reviewe

No full textThis is a generalizability attempt on the claim 4 claim:
Most importantly, there was a significant certainty x objective ambivalence interaction, B = .04,t(169) = 2.28, p = .02, 95% CI: [.01, .07].
from Luttrell et al (2016).
The statistical evidence is: B = .04,t(169) = 2.28, p = .02, 95% CI: [.01, .07].
The original claim states that attitudinal certainty is most strongly positively related to naturally-occuring attitude stability when attitudinal ambivalence is low. That is, given a specific attitude, those highest in attitudinal certainty, who also are low in ambivalence, will show the lowest variability in this specific attitude across time.
We test whether the conceptual variables attitude certainty and attitude ambivalence also predict attitude stability in response to an active persuasion attempt. This will occur in a self-persuasion paradigm. We test whether when participants are instructed to produce counter-attitudinal arguments, whether certainty and ambivalence also interact to predict resistance to persuasion? This generalizes the original finding from the domain of natural fluctuation in attitudes to the domain of active persuasion.
We also generalize by testing whether different measures of ambivalence and certainty yield similar results predicting attitudes in response to self-persuasion attempts. The original study found that measures of “objective” ambivalence interacted with certainty to predict differences in attitude stability. However, other work (e.g. Clarkson et al., 2008) shows that ambivalence induced in the form of homo- versus heterogenous information about an attitude object can interact with certainty (operationalized as source credibility). We use both the ambivalence measure used by Luttrell and a different measure of subjective ambivalence to see whether this effect generalizes.
The original claim had to do with the durability of the attitude across two time points. We generalize this test to other correlates of attitude strength. We test whether the effects of certainty and ambivalence may also be observed using measures of behavioral intentions, attribution of liked vs. disliked policies to the person who is the attitude object, and a measure of intergroup emotions.
Specifically, we expect that T1 attitude will be less strongly associated with T2 behavioral intentions, attribution of liked vs. disliked policies to an attitude target, and intergroup emotions about the attitude target for those higher in attitude certainty and ambivalence--that certainty and ambivalence will interact
Pelevin’s Trinity in the novel “t”: author – protagonist – reader
No full textThe article attempts to interpret Pelevin's artistic strategy in the novel "T" by exploring its subject organization and addressing the key problems of the author, the protagonist, and the reader as they are seen by the researcher. The article analyzes the peculiarities of constructing the narrative reality in the novel "T", and goes on to discuss Pelevin's philosophic models of the development of the humankind, and the emergence of his new anthropology
Measuring industry-science links through inventor-author relations: A profiling method
No full textIn this pilot study we examine the performance of text-based profiling in recovering a set of validated inventor-author links. In a first step we match patents and publications solely based on their similarity in content. Next, we compare inventor and author names on the highest ranked matches for the occurrence of name matches. Finally, we compare these candidate matches with the names listed in a validated set of inventor-author names. Our text-based profile methodology performs significantly better than a random matching of patents and publications, suggesting that text-based profiling is a valuable complementary tool to the name searches used in previous studies.innovation; industry-science links; text-based profiling;
Wave turbulence of a rotating array of quantized vortices in the T → 0 temperature limit
No full textThe dynamics of quantized vortices in the zero temperature limit is currently of great interest, particularly in the case of the Fermi superfluid He-B. Here we study wave turbulence, generated by the librating motion of a rotating cylindrical container filled with He-B, in the limit of vanishing viscous forces at temperatures . The polarization of the quantized vortices with respect to the axis of rotation is measured using non-invasive NMR techniques. We observe a decrease of the polarization when the librating motion is started, and a two-stage relaxation process when the modulation of the rotation velocity is stopped. The first relaxation process is associated with the dissipation of large-scale flow stored in inertial waves and the solid body rotation of the vortex array. From the decay of these energy reservoirs we determine the rate of energy dissipation of large-scale flow. The later second process is related to the relaxation of Kelvin waves on individual vortices. This process is monitored by the recovery of the polarization. The existence of a Kelvin wave cascade at the lowest temperatures is currently a central open question. We supply some evidence for the cascade
