Abstract Antibody-dependent cellular cytotoxicity (ADCC) responses to viral infection are a form of antibody regulated immune mediated through the Fc fragment. Whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) triggered ADCC contributes COVID-19 disease development is currently not well understood. To understand potential correlation between and development, we analyzed activity neutralizing response in 255 individuals ranging from asymptomatic fatal infections over 1 year...

A typical data-dissemination sensor network consists of a large number nodes, which are normally energy-constrained and unlikely to be recharged in field. Redundant nodes often deployed increase robustness, extend lifetime. Target inquirer mobilities further bring more challenges large-scale networks. Frequent location updates for multiple inquirers targets can drain the limited onboard energy excessively. We present EEDD, an energy-efficient protocol address both target mobility problem...

It has been a big challenge to develop routing protocol that can meet different application needs and optimize paths according the topology change in mobile ad hoc networks. Basing their forwarding decisions only on local topology, geographic protocols have drawn lot of attentions recent years. However, inaccurate knowledge outdated destination position information lead inefficient even failure. Proactive distribution hardly adapt traffic demand. is also difficult pre-set parameters...

Background: It is unknown whether unstable chondral lesions observed during arthroscopic partial meniscectomy (APM) require treatment. We examined differences at 1 year with respect to knee pain and other outcomes between patients who had debridement (CL-Deb) those observation (CL-noDeb) of encountered APM. Methods: Patients were ≥30 years old undergoing APM randomized receive (CL-Deb group; n = 98) or (CL-noDeb; 92) Outerbridge grade-II, III, IV lesions. Outcomes evaluated preoperatively 8...

Group communications are important in mobile ad hoc networks (MANET). Multicast is an efficient method to implement the group communications. However, it challenging scalable, robust and multicast MANET due difficulty membership management, packet forwarding maintenance of a tree-or mesh-based structure over dynamic topology for large size or network size. We propose novel scalable geographic protocol (RSGM). Scalable management has been performed through zone-based structure, location...

Background: Chondral lesions are commonly encountered during arthroscopic partial meniscectomy (APM); however, it is unknown how these affect postoperative outcomes. Purpose: The authors compared outcomes among patients with and without unstable chondral 1 year after APM. Study Design: Cohort study; Level of evidence, 3. Methods: conducted a secondary analysis data from the ChAMP (Chondral Lesions Meniscus Procedures) randomized controlled trial. They following for that were left in situ...

Background: Bone marrow lesions (BMLs) have been found on magnetic resonance imaging in patients with meniscal tears. Purpose: We sought to determine the prevalence and location of BMLs, association between BMLs chondral lesions, pain without radiographic evidence degenerative joint disease who underwent arthroscopic partial meniscectomy (APM). Study Design: Cohort study; Level evidence, 2. Methods: performed a secondary analysis Chondral Lesions And Meniscus Procedures (ChAMP) randomized...

Understanding the limitation of solely relying on statistical significance, researchers have proposed methods to draw biomedical conclusions based clinical significance. The minimal clinically important significance is one most fundamental concepts study Based an anchor question usually available in patients' reported outcome, Hedayat et al. presented a method estimate using classification technique. However, their implicitly requires that binary outcome equally likely, i.e. balanced...

Generating keys and keeping them secret is critical in secure communications. Due to the "open-air" nature, key distribution more susceptible attacks wireless An ingenious solution generate common by two communicating parties separately without need of exchange or distribution, regenerate on needs.

The purpose of this study was to examine the effect debridement (CL-Deb) versus observation (CL-noDeb) unstable chondral lesions on knee pain 5 years after arthroscopic partial meniscectomy (APM) in patients enrolled Chondral Lesions And Meniscus Procedures (ChAMP) Trial. Secondarily, other symptoms, function, general health, and rate additional surgery affected were examined.Patients aged ≥30 who had an Outerbridge grade-II, III, or IV lesion when undergoing APM randomly allocated CL-Deb (n...

The Earth's weather system encompasses intricate data modalities and diverse understanding tasks, which hold significant value to human life. Existing data-driven models focus on single tasks (e.g., forecasting). Although these have achieved promising results, they fail tackle various complex within a unified model. Moreover, the paradigm that relies limited real observations for scenario hinders model's performance upper bound. In response limitations, we draw inspiration from in-context...

With the improved knowledge on clinical relevance and more convenient access to patient-reported outcome data, researchers prefer adopt minimal clinically important difference (MCID) rather than statistical significance as a testing standard examine effectiveness of certain intervention or treatment in trials. A practical method determining MCID is based diagnostic measurement. By using this approach, can be formulated solution large margin classification problem. However, only produces...

Abstract Human metapneumovirus (hMPV), a newly-recognized member of the Paramyxoviridae family, mediate serious lower respiratory tract illness in very young children, elderly and immunocompromised patients. The mechanisms that regulate host immune response to hMPV are largely unknown. IL-12b is an important mediator limiting lung inflammation Th2 responses. However, relative contributions viral pathogenesis have not been extensively studied. We observed infection induces robust sustained...
