dimension 4 over finite fields
The Intersection of Two Fermat Hypersurfaces in P^3 via Computation of Quotient Curves
We study the intersection of two particular Fermat hypersurfaces in
over a finite field. Using the Kani-Rosen decomposition we study
arithmetic properties of this curve in terms of its quotients. Explicit
computation of the quotients is done using a Gr\"obner basis algorithm. We also
study the -rank, zeta function, and number of rational points, of the modulo
reduction of the curve. We show that the Jacobian of the genus 2 quotient
is -split
Barriers to older adults’ uptake of mobile-based mental health interventions
Background
To address increasing demand of mental healthcare treatments for older adults and the need to reduce delivery costs, healthcare providers are turning to mobile applications. The importance of psychological barriers have been highlighted in the uptake of mobile-based mental health interventions and efforts have been made to identify these barriers in order to facilitate initial uptake and acceptance. However, limited research has focused on older adults’ awareness of these applications and factors that might be hindering their use.
Objective
The purpose of this study was to explore the perceived barriers that older adults experience in the uptake of mobile-based mental health interventions.
Methods
Semi-structured interviews were conducted with a sample of 10 older adults, 50 years or older (female = 7, mean age = 68 years), who experienced periods of low mood. National Health Service applications were demonstrated to facilitate conversation and explore participants’ understanding of mental health and mobile-based mental health interventions. Thematic analysis was used to analyse the interview transcripts.
Results
The social ecological model was adopted as an organising framework for the thematic analysis which identified six distinct barriers to older adults’ uptake of mobile-based mental health interventions: mental electronic-health (e-health) awareness, interaction with technology, discontinuation, ‘seeing’ facilitates therapeutic alliance, incongruent role of the general practitioner and privacy and confidentiality.
Conclusions
Older adults experience a number of barriers to uptake ranging from the individual level to a macro, organisational level. The practical implications of these barriers are discussed such as the need for increased awareness of mobile-based mental health interventions among older adults
Communication is key during a public health threat like Zika and India has fallen short
Even if an isolated case is detected, the government needs to tell the public so as to prepare for the possibility of an outbreak
Formation of double ring patterns on Co2MnSi Heusler alloy thin film by anodic oxidation under scanning probe microscope
Double ring formation on Co2MnSi (CMS) films is observed at electrical
breakdown voltage during local anodic oxidation (LAO) using atomic force
microscope (AFM). Corona effect and segregation of cobalt in the vicinity of
the rings is studied using magnetic force microscopy and energy dispersive
spectroscopy. Double ring forma-tion is attributed to the interaction of
ablated material with the induced magnetic field during LAO. Steepness of
forward bias transport characteristics from the unperturbed region of the CMS
film suggest a non equilibrium spin contribution. Such mesoscopic textures in
magnetic films by AFM tip can be potentially used for memory storage
applications.Comment: 7 pages, 5 figure
Noise correction on LANDSAT images using a spline-like algorithm
Many applications using LANDSAT images face a dilemma: the user needs a certain scene (for example, a flooded region), but that particular image may present interference or noise in form of horizontal stripes. During automatic analysis, this interference or noise may cause false readings of the region of interest. In order to minimize this interference or noise, many solutions are used, for instane, that of using the average (simple or weighted) values of the neighboring vertical points. In the case of high interference (more than one adjacent line lost) the method of averages may not suit the desired purpose. The solution proposed is to use a spline-like algorithm (weighted splines). This type of interpolation is simple to be computer implemented, fast, uses only four points in each interval, and eliminates the necessity of solving a linear equation system. In the normal mode of operation, the first and second derivatives of the solution function are continuous and determined by data points, as in cubic splines. It is possible, however, to impose the values of the first derivatives, in order to account for shapr boundaries, without increasing the computational effort. Some examples using the proposed method are also shown
