TL;DR: In this article, a single-well softening model was used to control the nonlinear dynamics of an electrically actuated microbeam and the dynamic pull-in of the microbeam.
Abstract: This work deals with the problem of controlling the nonlinear dynamics, in general, and the dynamic pull-in, in particular, of an electrically actuated microbeam. A single-well softening model recently proposed by Gottlieb and Champneys [1] is considered, and a control method previously proposed by the authors is applied. Homoclinic bifurcation, which triggers the safe basin erosion eventually leading to pull-in, is considered as the undesired event, and it is shown how appropriate controlling superharmonics added to a reference harmonic excitation succeed in shifting it towards higher excitation amplitudes. An optimization problem is formulated, and the optimal excitation shape is obtained. Extensive numerical simulations aimed at checking the effectiveness of the control method in shifting the erosion of the safe basin are reported. They highlight good performances of the control method beyond theoretical expectations.

TL;DR: In the real-world setting, everolimus is safe and effective for the treatment of NETs of different origins, and this finding prompts caution when using this drug in pretreated patients and raises the issue of planning forEverolimus before PRRT and chemotherapy in the therapeutic algorithm for advanced NETs.
Abstract: Everolimus is a valid therapeutic option for neuroendocrine tumors (NETs); however, data in a real-world setting outside regulatory trials are sparse. The aim of this study was to determine everolimus tolerability and efficacy, in relation to previous treatments, in a compassionate use program. A total of 169 patients with advanced progressive NETs treated with everolimus were enrolled, including 85 with pancreatic NETs (pNETs) and 84 with nonpancreatic NETs (non-pNETs). Previous treatments included somatostatin analogs (92.9%), peptide receptor radionuclide therapy (PRRT; 50.3%), chemotherapy (49.7%), and PRRT and chemotherapy (22.8%). Overall, 85.2% of patients experienced adverse events (AEs), which were severe (grade 3–4) in 46.1%. The most frequent severe AEs were pneumonitis (8.3%), thrombocytopenia (7.7%), anemia (5.3%), and renal failure (3.5%). In patients previously treated with PRRT and chemotherapy, a 12-fold increased risk for severe toxicity was observed, with grade 3–4 AEs reported in 86.8% (vs. 34.3% in other patients). In addition, 63.3% of patients required temporarily everolimus discontinuation due to toxicity. Overall, 27.8% of patients died during a median follow-up of 12 months. Median progression-free survival (PFS) and overall survival (OS) were 12 months and 32 months, respectively. Similar disease control rates, PFS, and OS were reported in pNETs and non-pNETs. In the real-world setting, everolimus is safe and effective for the treatment of NETs of different origins. Higher severe toxicity occurred in patients previously treated with systemic chemotherapy and PRRT. This finding prompts caution when using this drug in pretreated patients and raises the issue of planning for everolimus before PRRT and chemotherapy in the therapeutic algorithm for advanced NETs.

TL;DR: In this paper, the authors reviewed and analyzed nearshore flows by means of the classic nonlinear shallow water equations with a specific focus on the interdependence between physical phenomena, model equations, and numerical schemes.
Abstract: Modeling of nearshore flows by means of the classic nonlinear shallow water equations is reviewed and analyzed with a specific focus on the interdependence between physical phenomena, model equations, and numerical schemes. Numerical benchmarking solutions for coastal applications are summarized. Strengths and limits of the nonlinear shallow water equations to reproduce the fundamental features of coastal flows are illustrated along with indications on needed improvements.

TL;DR: It is suggested that severe internal carotid artery stenosis can be considered as a marker of a faster rate of progression of the cognitive decline in AD and cerebral hemodynamic evaluation could be applied to identify patients at higher risk of rapid cognitive decline.
Abstract: The aim of this 12-month prospective study was to establish whether severe internal carotid artery stenosis is associated with faster progression of the cognitive impairment in patients with Alzheimer's disease (AD). Four hundred and eleven patients with AD underwent extracranial carotid Doppler ultrasound evaluation. Cerebrovascular reactivity to hypercapnia was measured by means of the breath-holding index (BHI) in those with severe carotid artery stenosis using transcranial Doppler ultrasonography. Cognitive status was quantified with the Mini Mental State Evaluation (MMSE). Ninety-eight patients had severe carotid artery stenosis, 41 right (group 1), and 57 left (group 2), while 313 had no significant stenosis (group 3). Group 1 and 2 patients showed an increased probability compared with group 3 patients to develop severe dementia (MMSE scores < 21) during the 12-month follow-up period: OR 2.36 (95% CI: 1.14-4.87) and OR 4.90 (95% CI: 2.65-9.04), respectively (p < 0.05, multiple logistic regression analysis). A BHI value ipsilateral to the stenosis < 0.69 predicted a worse MMSE score at 12 months irrespective of the side of the stenosis. These findings suggest that severe internal carotid artery stenosis can be considered as a marker of a faster rate of progression of the cognitive decline in AD. They also indicate that cerebral hemodynamic evaluation could be applied to identify patients at higher risk of rapid cognitive decline, who may benefit from aggressive treatment, and warrant investigation of the advantages of carotid revascularization procedures in these patients.
