Abstract:

The fundamental focus of field theory is the investigation of algebraic extensions of fields, while the investigation of the structures of algebra known as groups is what is covered in group theory. The Galois theory is a branch of algebraic mathematics that studies the connection between these two other subfields of the subject. Everest Galois, a French mathematician, is credited with being the first person to have the idea for it, which he had around the turn of the 19th century. Galois theory offers a complete view of the solutions that may be found for polynomial equations and investigates

Abstract: When we look at a picture, we tend to remember it by enriching the constructed mental representation with elements not present but probable outside the current view. The tendency to remember the perceived view with a broader scope is known as boundary extension (BE). Does BE benefit from paying reduced attention to the picture? While attention plays a central role in memory, only a few studies to date have investigated this question in the field of BE. In this research, participants completed a BE task in single- and dual-task conditions. The results indicate that BE is eliminated wh

We study the structure of function fields of plane quartic curves by using projections. Taking a point P ∈ ℙ2, we define the projection from a curve C to a line l with the centre P. This projection induces and extension field k (C)/k (ℙ1). By using this fact, we study the field extension k (C)/k (ℙ1) from a geometrical point of view. In this note, we take up quartic curves with singular points.

A novel single camera combined with Risley prisms is proposed to achieve a super-resolution (SR) imaging and field-of-view extension (FOV) imaging method.

For the FOV extension, we provide a new scheme for the scanning position path of the Risley prisms and the number of image acquisitions, which improves the acquisition efficiency and reduc

Through the regularization downward continuation of gravity and magnetic anomalies, the depth of the field source can be solved. However, due to the Gibbs effect, the horizontal resolving power of the field source is poor.

Abstract:

The latest technical development in the field of positron emission tomography/computed tomography (PET/CT) imaging has been the extension of the PET axial field-of-view. As a result of the increased number of detectors, the long axial field-of-view (LAFOV) PET systems are not only characterized by a larger anatomical coverage but also by a substantially improved sensitivity, compared with conventional short axial field-of-view PET systems. In clinical practice, this innovation has led to the following optimization: (1) improved overall image quality, (2) decreased duration of PET examinations,

Abstract:

Several limitations reduce the field of view in radio-interferometry. With an optical array, two of them can be overcome to some extent according to the beam combination method. A beam combination in the pupil plane can completely overcome one of them. In the image plane, a beam combination obeying the rules of geometrical optics can overcome both limitations in principle, but is difficult to achieve in practice. We discuss particularly the real case of a Michelson Stellar Interferometer where a periscope partially re-introduces these limitations, yielding a trade-off between the extension of

Truncation artifacts in MVCT can compromise registration accuracy with the planned kilovoltage computed tomography (KVCT) and hinder subsequent MVCT-based adaptive planning.

Classical motion of a charged particle in an electromagnetic field is described by the Lorentz equation in terms of the field components. The field is defined by the infinitesimal gauge group elements associated with closed curves. The Lorentz equation may be derived from the action principle with an appropriate Lagrangian. The Lagrangian may also be used to associate group elements with curves in the space-time manifold. The action principle is shown here to be an equivalence relation between the infinitesimal elements so defined for a collection of closed curves and the identity element. Thi

Abstract:

We employed a double-layer coupled diffractive optical element, based on metasurfaces and diffraction gratings, which exhibits wavefront modulation and chromatic dispersion compensation. Utilizing this double-layer coupled diffractive optical element in the optical information transmission process of a diffractive waveguide allows for the transmission of color image information using a single-layer waveguide structure. Our results demonstrate that, under the conditions of a field of view of 47° × 47°, an entrance pupil size of 2.9 × 2.9 mm2, and an exit pupil extension size of 8.9 mm, the unif

Abstract:

The dependence of photochemistry on excitation wavelength is not a recently observed phenomenon; nonetheless, it has, surprisingly enough, been largely ignored in the field. The reasons for this situation are not fully understood but might be related to a provisional extension of Kasha’s rule to photochemistry, or perhaps to a difficulty to justify the kind of short time-scales implied in such photochemistry, that challenges the usually held view giving predominance to fast internal conversion and vibrational relaxation. Regardless of the reasons, it is still a matter of fact that a complete a

Access to appropriate and timely agricultural extension services has remained an enduring input in the alleviation of rural poverty. A pluralistic approach to agricultural extension services by government, farmer-based organizations, non-governmental organizations (NGOs) and active participants in the agricultural value chain will help facilitate the needed advisory services in order to achieve improvement in livelihoods and reduce vulnerability. The exponential growth rate resulting in a population explosion, fast-rising vagaries in technology use, heightened increase in livelihood vulnerabil

Full text

Abstract:

Holotomography is an extension of computed tomography where samples with low X-ray absorption can be investigated with higher contrast. In order to achieve this, the imaging system must yield an optical resolution of a few micrometers or less, which reduces the measurement area (field of view = FOV) to a few mm at most. If the sample size, however, exceeds the field of view (called local tomography or region of interest = ROI CT), filter problems arise during the CT reconstruction and phase retrieval in holotomography. In this paper, we will first investigate the practical impact of these filt

Abstract:

Laser focusing of atoms has emerged as a viable form of nanofabrication. Structures are formed by focusing chromium atoms as they deposit onto a surface. The focusing occurs in a standing-wave laser field in one or two dimensions, resulting in arrays spaced at exactly half the laser wavelength (λ/2 = 212�78 nm). Atomic force, scanning electron, and transmission electron microscopies are used to view the fabricated structures. Improvements in the technique, including narrowing of the linewidth and extension to two dimensions are discussed. Theoretical predictions for the shape of the deposited

Because field trials often necessitate less detailed measurments than are possible in a true research environment, they are often believed to represent a poorer form of science. However, this is a very short-sighted view because there are particular benefits to be derived from carefully designed and conducted field trials which cannot be satisfied by smaller, more detailed studies.Within the context of reproduction research the objective is to understand the basic physiological mechanisms controlling reproduction, and to identify the nature and extent of reproductive wastage and its causes.

Abstract:

Mucoceles of the paranasal sinuses cause progressive distension of the bony walls and induce compressive symptoms. Although rare, cases of massive intracranial extension have occurred. We believe that an endoscopic transnasal approach is the best choice for such huge mucoceles because it is the least invasive and can provide an adequate surgical field of view for wide marsupialization. However, the results of long-term follow-up after endoscopic transnasal surgery have not been reported.

Abstract:

We propose to analyze a modified electromagnetism inspired from the gauge sector of the Standard Model extension (SME). From the point of view of a canonical formulation, we carried out the usual analysis on the constraints structure of the odd sector (Carroll–Field–Jackiw term) and a Maxwell term with an effective metric. This effective metric is obtained by a vectorial decomposition of the CPT-even term, that is absorbed in the ordinary Maxwell term. Using symplectic projector method (SPM), we obtain the dispersions relations and we have verified conditions of stability to determine the vali
