The Baouendi-Treves approximation Theorem for Gevrey classes and applications
In this work we show how to extend the seminal Baouendi-Treves approximation
theorem for Gevrey functions and ultradistributions. As applications we present
a Gevrey version of the approximate Poincar\'e Lemma and study
ultradistributions vanishing on maximally real submanifolds
Systemic lupus erythematosus and implications for the oral cavity
Systemic Lupus Erythematosus affects several people around the world
and because it is characterized as a chronic inflammatory disease of
multifactorial origin, and with systemic impairment, great attention
must be paid from diagnosis to treatment in order to optimize the entire
follow-up of the patient.
The dental doctor plays an important role in the diagnosis of the
condition and must be attentive to the early signs that can appear in
the oral cavity with a frequency of up to 21%.
In this way, through this bibliographic review, which has as main goal to
correlate Systemic Lupus Erythematosus with its direct consequences
in the oral cavity, it will be possible to help dentists in the diagnosis, to
understand in detail the development of the disease and what attitude
should be taken in its presence.info:eu-repo/semantics/publishedVersio
ANALISIS TATANIAGA KUBIS (Brassica Oleraceae) (Studi Kasus Di Desa Deles Kecamatan Bawang Kabupaten Batang)
Deles village is one of cabbages producers that located near with the economic central in Bawang District. The distance between Deles and Bawang which is near, has advantage for the cabbages farmer to distribute their agricultural produce. The objectives of the research are 1). To know the pattern of trading system 2). To determine the amount of profits earned by farmers in various pattern of trading system 3). To know the efficiency of cabbages trading system based on marketings margin, farmer's share, and profit ratio. The location of research selected by purposive method, that is Deles Village, because Deles Village is the largest producer of cabbage in Bawang District. The number of farmers were selected as respondent are 30 farmers who own land, which consist of 15 farmers from Mulya Sari farmers group and 15 farmers from Subur Makmur farmers group. Sampling method of marketing agencies conducted by snowball sampling method. The research used qualitative and quantitative analysis methods. Based on the results of the research, there are three pattern of cabbage trading system in Deles Village, which are zero level, one level, and two level of cabbage trading system. Zero level of cabbage consist of farmers ā consumers, the one level consist of farmers ā retailers ā consumers. and two level consist of farmers ā collectors ā retailers ā consumers. There are 5 farmers who are involved in zero level of cabbage trading system, 13 farmers who are involved in one level, and 12 farmers who are involved in two level. The biggest profits are obtained by farmers in cabbage trading system zero level, that is Rp 691,64 /kg. The most efficient cabbage is trading system two level, with a marketing margin of Rp 2.175 /kg, farmer's share of 20,90 %, and a profit ratio Rp 2,21 /kg
Neuronal assembly dynamics in supervised and unsupervised learning scenarios
The dynamic formation of groups of neuronsāneuronal assembliesāis believed to mediate cognitive phenomena at many levels, but their detailed operation and mechanisms of interaction are still to be uncovered. One hypothesis suggests that synchronized oscillations underpin their formation and functioning, with a focus on the temporal structure of neuronal signals. In this context, we investigate neuronal assembly dynamics in two complementary scenarios: the first, a supervised spike pattern classification task, in which noisy variations of a collection of spikes have to be correctly labeled; the second, an unsupervised, minimally cognitive evolutionary robotics tasks, in which an evolved agent has to cope with multiple, possibly conflicting, objectives. In both cases, the more traditional dynamical analysis of the systemās variables is paired with information-theoretic techniques in order to get a broader picture of the ongoing interactions with and within the network. The neural network model is inspired by the Kuramoto model of coupled phase oscillators and allows one to fine-tune the network synchronization dynamics and assembly configuration. The experiments explore the computational power, redundancy, and generalization capability of neuronal circuits, demonstrating that performance depends nonlinearly on the number of assemblies and neurons in the network and showing that the framework can be exploited to generate minimally cognitive behaviors, with dynamic assembly formation accounting for varying degrees of stimuli modulation of the sensorimotor interactions
Wigner phase space distribution as a wave function
We demonstrate that the Wigner function of a pure quantum state is a wave
function in a specially tuned Dirac bra-ket formalism and argue that the Wigner
function is in fact a probability amplitude for the quantum particle to be at a
certain point of the classical phase space. Additionally, we establish that in
the classical limit, the Wigner function transforms into a classical
Koopman-von Neumann wave function rather than into a classical probability
distribution. Since probability amplitude need not be positive, our findings
provide an alternative outlook on the Wigner function's negativity.Comment: 6 pages and 2 figure
A multi-objective-based approach for Fair Principal Component Analysis
In dimension reduction problems, the adopted technique may produce
disparities between the representation errors of two or more different groups.
For instance, in the projected space, a specific class can be better
represented in comparison with the other ones. Depending on the situation, this
unfair result may introduce ethical concerns. In this context, this paper
investigates how a fairness measure can be considered when performing dimension
reduction through principal component analysis. Since both reconstruction error
and fairness measure must be taken into account, we propose a
multi-objective-based approach to tackle the Fair Principal Component Analysis
problem. The experiments attest that a fairer result can be achieved with a
very small loss in the reconstruction error

New determinations of gamma-ray line intensities of the Ep = 550 keV and Ep = 1747 keV resonances of the 13-C(p,gamma)14-N reaction
Gamma-ray angular distributions for the resonances at Ep = 550 keV and 1747
keV of the radiative capture reaction 13-C(p,g)14-N have been measured, using
intense proton beams on isotopically pure 13-C targets. Relative intensities
for the strongest transitions were extracted with an accuracy of typically five
per cent, making these resonances new useful gamma-ray standards for efficiency
calibration in the energy range Egamma = 1.6 to 9 MeV.Comment: 17 pages, 6 figures, Nuclear Instruments and Methods, Sec. A,

Using metamemory measures and memory tests to estimate eyewitness free recall performance
Using a mock witness methodology, we investigated the predictive value of metamemory measures and objective memory tests as indicators of eyewitness free recall performance. Participants (n = 208) first completed a metamemory assessment that included assessments of self-rated memory capacity, memory development and use of strategies. In a separate session, participants watched a mock-crime video and provided a free recall account, followed by one out of four independent memory tests (i.e., free recall, cued recall, face recognition and general knowledge). Accuracy, amount of details reported, confidence and over/underconfidence in the eyewitness free recall were the main dependent variables. Results indicated three main findings: (1) subjective assessments of memory capacity were not related to eyewitness free recall performance; (2) although individual confidence and over/underconfidence was somewhat stable across different memory tests, accuracy was less stable; and (3) individuals with higher self-rated memory capacity had a slightly stronger confidence-accuracy relation in free recall. These results are discussed with respect to metamemory assessments and performance stability across memory tests of different domains
