Blowup for Biharmonic NLS [PDF]

open access: yesAnnales scientifiques de l'École normale supérieure, 2015
We consider the Cauchy problem for the biharmonic (i.\,e.~fourth-order) NLS with focusing nonlinearity given by $i \partial_t u = \Delta^2 u - \mu \Delta u -|u|^{2 \sigma} u$ for $(t,x) \in [0,T) \times \mathbb{R}^d$, where $0 < \sigma 4/d$, we prove a ...

Pharmacokinetics and safety of highly variable nitroglycerin lingual spray (NLS) versus US-licensed nitroglycerin lingual spray reference product (Nitrolingual®): a randomized, four-cycle, four-sequence, partially replicated crossover Phase I bioequivalence clinical trial [PDF]

open access: yesFrontiers in Pharmacology
PurposeIn this Phase I study, we aimed to evaluate the pharmacokinetic bioequivalence and the safety of a nitroglycerin lingual spray (NLS) compared with US-approved Nitrolingual in healthy subjects.MethodsSubjects (N = 56) were randomized 1:1 to receive

Threshold scattering for the 2D radial cubic-quintic NLS [PDF]

open access: yesCommunications in Partial Differential Equations, 2021
We consider the cubic-quintic nonlinear Schrödinger equation in two space dimensions. For this model, X. Cheng established scattering for data with mass strictly below that of the ground state for the cubic NLS. Subsequently, R. Carles and C.

Dbar‐approach to coupled nonlocal NLS equation and general nonlocal reduction [PDF]

open access: yesStudies in applied mathematics (Cambridge), 2021
The coupled nonlocal nonlinear Schrödinger (NLS) equation is studied by virtue of the 2×2 Dbar‐problem. Two spectral transform matrices are introduced to define two associated Dbar‐problems.

Advantages of Using Transfer Learning Technology with a Quantative Measurement

open access: yesRemote Sensing, 2023
The number of people living in cities is continuously growing, and the buildings in topographic maps are in need of frequent updates, which are costly to perform manually. This makes automatic building extraction a significant research subject.

A Novel Deep Multi-Image Object Detection Approach for Detecting Alien Barleys in Oat Fields Using RGB UAV Images

open access: yesRemote Sensing, 2023
Oat products are significant parts of a healthy diet. Pure oat is gluten-free, which makes it an excellent choice for people with celiac disease. Elimination of alien cereals is important not only in gluten-free oat production but also in seed production.

Mapping Small Watercourses from DEMs with Deep Learning—Exploring the Causes of False Predictions

open access: yesRemote Sensing, 2023
Vector datasets of small watercourses, such as rivulets, streams, and ditches, are important for many visualization and analysis use cases. Mapping small watercourses with traditional methods is laborious and costly.
