BACKGROUND The characteristics of human immunodeficiency virus (HIV) exposure that determine the induction of HIV-specific T cells and, in particular, T helper cells are not well understood. METHODS HIV-1 Gag- and Env-specific T helper cells were analyzed by use of an interferon (IFN)- gamma enzyme-linked immunosorbent spot (ELISPOT) assay and by use of IFN- gamma secretion flow cytometry. Re...

•It is reported the first endometrial stromal nodule (ESN) in the vagina.•This is an excepcionall ESN because it was not associated with endometriosis•It was successfully treated by local resection.•Primary vulvovaginal endometrial stromal neoplasms are rare (only 5 reported).

OBJECTIVE The Enriched Semantic Network (ESN) was introduced as an extension of the Unified Medical Language System (UMLS) Semantic Network (SN). Its multiple subsumption configuration and concomitant multiple inheritance make the ESN's relationship structures and semantic type assignments different from those of the SN. A technique for deriving the relationship structures of the ESN's semantic...

Interest in chaotic time series prediction has grown recent years due to its multiple applications fields such as climate and health. In this work, we summarize the contribution of works that use different machine learning (ML) methods predict series. It is highlighted challenge predicting larger horizon with low error, for task, majority authors datasets generated by systems Lorenz, Rössler Ma...

The development of specialist nursing practice has blurred the boundaries between medicine and nursing. This mainly qualitative study compares the structure of epilepsy specialist nurse (ESN) and consultant neurologist (CN) clinical interviews at first seizure presentation and opinion on diagnosis. Twenty patients with a suspected first seizure were randomly allocated for clinical review with a...

We prove that the sequence (eSn )n≥0 of excursions in the quarter plane corresponding to a nonsingular step set S ⊆ {0,±1} with infinite group does not satisfy any nontrivial linear recurrence with polynomial coefficients. Accordingly, in those cases, the trivariate generating function of the numbers of walks with given length and prescribed ending point is not D-finite. Moreover, we display th...

Reservoir computing (RC) refers to a new class of state-space models with a fixed state transition structure (the “reservoir”) and an adaptable readout from the state space. The reservoir is supposed to be sufficiently complex so as to capture a large number of features of the input stream that can be exploited by the reservoir-to-output readout mapping. The field of RC has been growing rapidly...

nvironmental degradation can inflict serious damage on poor people, because their livelihoods often depend on natural resource use, and their living conditions may offer little protection from pollution of the air, water and soil. At the same time, poverty-constrained options may induce the poor to deplete resources and degrade the environment at rates that are incompatible with long-term susta...
