The present study determined the effect of dexmedetomidine (Dex) combined with flurbiprofen axetil (FA) on analgesia, immune response, and preservation of cognitive function in patients subjected to general anesthesia. We recruited 100 patients with thyroid surgery and randomly divided them into four groups: Dex (D), FA (F), Dex combined with FA (DF), and saline control (C). The extubation and ...
This paper presents a novel and non-destructive approach to the appearance characterization and classification of commercial pork, turkey and chicken ham slices. Ham slice images were modelled using directional fractal (DF(0°;45°;90°;135°)) dimensions and a minimum distance classifier was adopted to perform the classification task. Also, the role of different colour spaces and the resolution le...
Lel G be a graph with vertex connectivi2y k(G). An important measure of the fault tolerance of G is its faul&diameler df(G), which is defined as the maximum diameter resulting from the deletion of any set of nodes containing less than k(G) nodes. The robustness of G is often measured by comparing d/(G) with the diameter of Ihe fault-free G, namely d(G). In particular, a family of graphs G, is d...
DS-CDMA can achieve good bit error rate (BER) performance in a severe frequency-selective fading channel by using frequency-domain equalization (FDE) based on MMSE criterion instead of rake combining. FDE requires accurate channel estimation (CE). Recently, a decision feedback (DF)MMSE-CE using a fixed DF filter coefficient has been proposed. The DF filter coefficient is an important design par...
Travelers have the potential both to acquire and to spread dengue virus infection. The incidence of dengue fever (DF) among European travelers certainly is underestimated, because few centers use standardized diagnostic procedures for febrile patients. In addition, DF is currently not reported in most European public health systems. Surveillance has commenced within the framework of a European ...
The Animal Verbal Fluency (AVF) and Design Fluency (DF) structured and unstructured test versions were administered to N = 294 healthy native Dutch-speaking children who were aged between 6.56 and 15.85 years. The AVF and DF structured test scores increased linearly as a function of age, whilst the relation between age and the DF unstructured test score was curvilinear (i.e., the improvement in...
Resumo—Uma discussão acurada baseada no modelo de sistema apresentado em [1] é realizada. Mais especificamente, uma modelagem de sistema mais realı́stica para redes sem fio multiusuário com relay é proposta. A partir dessa nova modelagem, expressões exatas e em forma fechada para as probabilidades de outage de protocolos fixos decodifica-e-encaminha (F-DF) e protolocos seletivos DF (S-DF) são ob...
[Purpose] This study investigated the reliability of ankle dorsiflexion passive range of motion (DF-PROM) measurements obtained using a goniometer and Biodex dynamometer in stroke patients. [Subjects] Fifteen stroke patients participated in this study. [Methods] Ankle DF-PROM was assessed using a goniometer and Biodex dynamometer. Ankle DF-PROM was measured during two sessions with 7 days betwe...
The so-called holographic electron density theorem (HEDT) is analyzed from an algebraic perspective, and a brief analytical point of view is also given. The connection of the HEDT with quantum similarity measures (QSM) over electronic density functions (DF) is studied using GTO functions, atomic ASA DF, and promolecular ASA DF. Restricted integration of QSM over a box of finite side length is d...
