description: We study the ability to control d-dimensional quantum systems (qudits) encoded in the hyperfine spin of alkali-metal atoms through the application of radio- and microwave-frequency magnetic fields in the presence of inhomogeneities in amplitude and detuning. Such a capability is essential to the design of robust pulses that mitigate the effects of experimental uncertainty and also for application to tomographic addressing of particular members of an extended ensemble. We study the problem of preparing an arbitrary state in the Hilbert space from an initial fiducial state. We prove that inhomogeneous control of qudit ensembles is possible based on a semi-analytic protocol that synthesizes the target through a sequence of alternating rf and microwave-driven SU(2) rotations in overlapping irreducible subspaces. Several examples of robust control are studied, and the semi-analytic protocol is compared to a brute force, full numerical search. For small inhomogeneities, < 1%, both approaches achieve average fidelities greater than 0.99, but the brute force approach performs superiorly, reaching high fidelities in shorter times and capable of handling inhomogeneities well beyond experimental uncertainty. The full numerical search is also applied to tomographic addressing whereby two different nonclassical states of the spin are produced in two halves of the ensemble.

description: Tra i detrattori della Citizen Science (CS), è pensiero comune che i dati raccolti dai cittadini (sensu lato) non siano qualitativamente validi per essere utilizzati in lavori di ricerca scientifica. Nonostante i numerosi studi che dimostrano l’infondatezza di questa opinione, rimane difficile poter far affermare i protocolli di raccolta dati basati sulla CS, come strumenti utili ad esempio, per il monitoraggio ambientale. CS4Rivers è un progetto di CS dell’Università di Siena, sviluppato nell’ ambito del National Biodiversity Future Center (NBFC) con fondi PNRR, che intende valutare la qualità degli habitat e la biodiversità del fiume Ombrone e dei suoi tributari. Tra le componenti dell’ecosistema fluviale che si intende analizzare, c’è anche la vegetazione riparia, data la sua fondamentale funzione ecologica di cui beneficia direttamente il fiume e il territorio circostante. In questo lavoro vengono presentati i risultati preliminari relativi alla qualità dei dati raccolti dai cittadini con una protocollo semplificato ideato ad hoc (RIVE) per il monitoraggio della vegetazione riparia. I dati di copertura percentuale di 12 specie target ricercate dai cittadini sono stati confrontati con quelli campionati da esperti botanici.
title: Learning from machine learning: prediction of age-related athletic performance decline trajectories

description: Factors that determine individual age-related decline rates in physical performance are poorly understood and prediction poses a challenge. Linear and quadratic regression models are usually applied, but often show high prediction errors for individual athletes. Machine learning approaches may deliver more accurate predictions and help to identify factors that determine performance decline rates. We hypothesized that it is possible to predict the performance development of a master athlete from a single measurement, that prediction by a machine learning approach is superior to prediction by the average decline curve or an individually shifted decline curve, and that athletes with a higher starting performance show a slower performance decline than those with a lower performance. The machine learning approach was implemented using a multilayer neuronal network. Results showed that performance prediction from a single measurement is possible and that the prediction by a machine learning approach was superior to the other models. The estimated performance decline rate was highest in athletes with a high starting performance and a low starting age, as well as in those with a low starting performance and high starting age, while the lowest decline rate was found for athletes with a high starting performance and a high starting age. Machine learning was superior and predicted trajectories with significantly lower prediction errors compared to conventional approaches. New insights into factors determining decline trajectories were identified by visualization of the model outputs. Machine learning models may be useful in revealing unknown factors that determine the age-related performance decline.

description: This study aims to evaluate the efficiency of electric fishing and seine-net/dip-net to obtain quantitative and qualitative data on the fish community of low conductivity streams in the semi-arid region of Bahia, Brazil. Samplings were collected in 15 streams in the region of Chapada Diamantina. Two homogeneous stretches with 50 m each were selected and closed with blocking nets. Zippin analysis was used to evaluate the suitability of each capture method. Differences in abundance, richness, composition of species, and length of specimens captured were compared for each method. Twenty-nine species were collected, twenty-four using electric fishing, and twenty-one using seine-net/dip-net. There were no significant differences between methods as for abundance, richness, composition of species, and length of the individual captured. There were no significant differences in capturability. Both methods have high values of sample efficiency (SE). Therefore, electric fishing and seine-net/dip-net are equally effective on describing qualitatively and quantitatively the fish community. It is noteworthy that for an ideal choice of collection method, the geomorphological characteristics of the streams must be taken into account since they exert a direct influence on both collection methods.

description: Guava (Psidium guajava) leaf is commonly used as a medicine against gastroenteritis and child diarrhea by those who cannot afford or do not have access to antibiotics. This study was aimed to determine the antibacterial activity of Guava leaf (Psidium guajava) extracts on E. coli using agar well diffusion method. Two different extracts were obtained from the guava leaf (aqueous-soluble and ethyl acetate soluble extracts). Psidium guajava leaves were extracted with water and ethyl acetate using maceration extraction method. Phytochemical screening of the Psidium guajava leaf extracts was carried out using standard methods. Agar well diffusion and agar dilution methods were employed to determine the zone of inhibition, minimum inhibitory concentration, and minimum bactericidal concentration. The antibacterial test results showed that the Psidium guajava ethyl acetate and aqueous extracts have potential antimicrobial activity against Gramnegative bacteria. The Ethyl acetate extract showed the maximum zone of inhibition on test isolates (17mm at 100mg/ml) While the Aqueous extract showed the least inhibitory effect on test isolates (8mm at a concentration of 12.5mg/ml). The minimum inhibitory concentration (MIC) showed that both E. coli isolates was sensitive to both Ethyl acetate and aqueous extract (at the lowest concentration of 12.5mg/ml). The minimum bactericidal concentration (MBC) of aqueous extract was 100mg/ml for both the isolates and ethyl acetate extract for 50mg/ml for both the isolates, this result indicate that Guava leaf extracts have antibacterial activities against the test isolates, and the Ethyl acetate extract is more effective compared to the aqueous extract.

description: We demonstrate a z-axis accelerometer which uses waveguided light to sense proof mass displacement. The accelerometer consists of two stacked rings (one fixed and one suspended above it) forming an optical ring resonator. As the upper ring moves due to z-axis acceleration, the effective refractive index changes, changing the optical path length and therefore the resonant frequency of the optical mode. The optical transmission changes with acceleration when the laser is biased on the side of the optical resonance. This silicon nitride "Cavity-enhanced OptoMechanical Accelerometer" (COMA) has a sensitivity of 22 percent-per-g optical modulation for our highest optical quality factor (Q_o) devices

description: While automatic detection of point sources in astronomical images has experienced a great degree of success, less effort has been directed towards the detection of extended and low-surface brightness features. At present, existing telescopes still rely on human expertise to reduce the raw data to usable images and then to analyse the images for non-pointlike objects. However, the next generation of radio telescopes will generate unprecedented volumes of data making manual data reduction and object extraction infeasible. Without developing new methods of automatic detection for extended and diffuse objects such as supernova remnants, bent-tailed galaxies, radio relics and halos, a wealth of scientifically important results will not be uncovered. In this paper we explore the response of the Circle Hough Transform to a representative sample of different extended circular or arc-like astronomical objects. We also examine the response of the Circle Hough Transform to input images containing noise alone and inputs including point sources.

One-step error correction for multipartite polarization entanglement

Publisher: name: arXiv
Year: 2011
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We present two economical one-step error-correction protocols for multipartite polarization-entangled systems in a Greenberger-Horne-Zeilinger state. One uses spatial entanglement to correct errors in the polarization entanglement of an N-photon system, resorting to linear optical elements. The other uses frequency entanglement to correct errors in the polarization entanglement of an N-photon system. The parties in quantum communication can obtain a maximally entangled state from each N-photon system transmitted with one step in these two protocols, and both of their success probabilities are 100%, in principle. That is, they both work in a deterministic way, and they do not largely consume the less-entangled photon systems, which is far different from conventional multipartite entanglement purification schemes. These features may make these two protocols more useful for practical applications in long-distance quantum communication.

description: Sarcophagid experts have made several efforts to associate biodiversity data and comprehend where each species occurs, but comprehensive faunal inventories remain scarce. Our aim was to provide a list of distributional patterns and endemic species and allow assessment of the sampling effort conducted within Brazilian biomes. We produced a dataset of Brazilian sarcophagids and overlaid with a biome map, to investigate distributional patterns, endemism and to build species accumulation curves. Additionally, we calculated nonparametric asymptotic species richness estimators and extrapolation of species diversity (Hill numbers). Our dataset comprised 288 sarcophagid species, which 21 were identified as endemic. The biomes with the highest species richness were the Atlantic Rainforest and the Amazon Forest, and no biome exhibited a stabilized asymptotic curve. This is the first proposal of listing Sarcophagidae species by biomes and essential to understand the spatial distribution of this family in Brazil. We present maps and richness estimators that allow identifying gaps and guiding survey planning.

description: Crocodilians injuries are indicators of their health and social interactions. We analyzed the prevalence and distribution of injuries in spectacled caiman (Caiman crocodilus chiapasius) from the Biosphere Reserve of La Encrucijada (BRLE) in relation to the habitat, size, and sex of individuals. We collected data on injuries in caimans captured during nocturnal surveys (2014–2022) in the estuary and swamps of the BRLE. We determined the sex of each caiman, measured their snout–vent length, and registered the type of injury and body region where injuries were detected. From all records, 102 of 301 caimans (33.9%) presented injuries and they were more likely to be injured in the estuary than in the swamps, probably due to the presence of a larger sympatric crocodile species in the estuary (Crocodylus acutus). Sex had no effect on the proportion of injured individuals, but larger caimans have a higher probability of being injured than smaller ones, explained by an ontogenetic change in the individuals’ behaviors. Habitat, sex, and size class of individuals do not influence the number of injuries on different body regions. The tail was the most injured body region (17.6% of individuals), followed by the abdomen (13.0%), back (12.6%), head (9.6%), and extremities (4.0%).

description: It was shown that tunneling current flowing through a system with Coulomb correlations leads to charge redistribution between the different localized states. Simple model consisting of two electron levels have been analyzed by means of Heisenberg motion equations taking into account all order correlations of electron filling numbers in localized states exactly. We consider various relations between Coulomb interaction and localized electron energies. Sudden jumps of electron density at each level in a certain range of applied bias have been found. We found that for some parameter range inverse occupation in the two-level system appeared due to Coulomb correlations. It was shown also that Coulomb correlations lead to appearance of negative tunneling conductivity at certain relation between the values of tunneling rates from the two electronic levels.

description: Nanoscopic rings pierced by external magnetic fields and asymmetrically connected to wires behave in sharp contrast with classical expectations. By studying the real-time evolution of tight-binding models in different geometries, we show that the creation of a magnetic dipole by a bias-induced current is a process that can be reversed: connected rings excited by an internal ac flux produce ballistic currents in the external wires. In particular we point out that, by employing suitable flux protocols, single-parameter nonadiabatic pumping can be achieved, and an arbitrary amount of charge can be transferred from one side to the other. We also propose a set up that could serve a memory device, in which both the operations of {\it writing} and {\it erasing} can be efficiently performed.

We also investigate the magnetic remanence and the electric coercivity.

description: Thermal properties of few-fermion (n < 5) systems are investigated. The dependence of the heat capacity on the topology and shape of the cavity containing the particles is analyzed. It is found that the maximum of the heat capacity, occuring at low T, discussed recently by Toutounji for a system with n = 1 fermions, is even more visible for n = 2, but fades away for n = 3 and 4. For large T, the classical behavior is obtained; however, when T -> 0, the heat capacity tends to zero exponentially, not linearly, as in macroscopic and even mesoscopic systems. The physical relevance of these results is discussed.

Year: 2019

description: Background: Gram-positive bacteria are common causes of both community acquired and nosocomial infections. This is compounded by the development of multi-drug resistance in this group of bacteria. The aim of this study is to characterize and evaluate drug susceptibility profile of Gram-positive cocci isolated from different clinical samples in the study area.

Objective: The main objective of this study was to determine the prevalence of gram positive cocci and multidrug resistance pattern of Gram positive cocci isolated from different clinical samples.

Methods: A laboratory based cross-sectional study was conducted to determine the prevalence of multidrug resistant strains of Gram-positive bacteria isolated from 792 patients referred to Arsho Advanced Medical Laboratory, from January to April 2018.Different clinical samples were collected and inoculated onto primary isolation culture media, blood culture bottles and blood agar. Preliminary identification was carried on based on number, type, morphology appearance of colonies and Gram reaction after growth on culture media. Identification and drug susceptibility testing also carried out by GP and AST-GP71 cards of the VITEK 2 compact systems

description: We derive and solve a Fokker-Planck equation for the stationary distribution of the free energy, in a model of unzipping of double-stranded DNA under external force. The autocorrelation function of the random DNA sequence can be a general form, including long range correlations. In the case of Orstein-Uhlenbeck noise, characterized by a finite correlation length, our result reduces to the exact result of Allahverdyan et al, with the average number of unzipped base pairs going as ~1/f^2 in the white noise limit, where f is the deviation from the critical force. In the case of long range correlated noise, where the integrated autocorrelation is divergent, we find that is finite at f=0, with its value decreasing as the correlations become longer range. This shows that long range correlations actually stabilize the DNA sequence against unzipping. Our result is also in agreement with the findings of Allahverdyan et al, obtained using numerical generation of the long range correlated noise.

Nonlinear Excitations in Strongly-Coupled Fermi-Dirac Plasmas

Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: In this paper we use the conventional quantum hydrodynamics (QHD) model in combination with the Sagdeev pseudopotential method to explore the effects of Thomas-Fermi nonuniform electron distribution, Coulomb interactions, electron exchange and ion correlation on the large-amplitude nonlinear soliton dynamics in Fermi-Dirac plasmas. It is found that in the presence of strong interactions significant differences in nonlinear wave dynamics of Fermi-Dirac plasmas in the two distinct regimes of nonrelativistic and relativistic degeneracies exist. Furthermore, it is remarked that first-order corrections due to such interactions (which are proportional to the fine-structure constant) are significant on soliton dynamics in nonrelativistic plasma degeneracy regime rather than relativistic one. In the relativistic degeneracy regime, however, these effects become less important and the electron quantum-tunneling and Pauli-exclusion dominate the nonlinear wave dynamics. Hence, application of non-interacting Fermi-Dirac QHD model to study the nonlinear wave dynamics in quantum plasmas such as compact stars is most appropriate for the relativistic degeneracy regime.

description: This paper presents the Discrete Wavelet based fusion techniques for combining perceptually important image features. SPIHT (Set Partitioning in Hierarchical Trees) algorithm is an efficient method for lossy and lossless coding of fused image. This paper presents some modifications on the SPIHT algorithm. It is based on the idea of insignificant correlation of wavelet coefficient among the medium and high frequency sub bands. In RE-MSPIHT algorithm, wavelet coefficients are scaled prior to SPIHT coding based on the sub band importance, with the goal of minimizing the MSE.

Ab Initio Estimates of the Size of the Observable Universe

description: When one combines multiverse predictions by Bousso, Hall, and Nomura for the observed age and size of the universe in terms of the proton and electron charge and masses with anthropic predictions of Carter, Carr, and Rees for these masses in terms of the charge, one gets that the age of the universe should be roughly the inverse 64th power, and the cosmological constant should be around the 128th power, of the proton charge. Combining these with a further renormalization group argument gives a single approximate equation for the proton charge, with no continuous adjustable or observed parameters, and with a solution that is within 8% of the observed value. Using this solution gives large logarithms for the age and size of the universe and for the cosmological constant that agree with the observed values within 17%.

description: The relativley large spread in the derived metallicities ([Fe/H]) of M dwarfs shows that various approaches have not yet converged to consistency. The presence of strong molecular features, and incomplete line lists for the corresponding molecules have made metallicity determinations of M dwarfs difficult. Furthermore, the faint M dwarfs require long exposure times for a signal-to-noise ratio sufficient for a detailed spectroscopic abundance analysis. We present a high-resolution (R~50,000) spectroscopic study of a sample of eight single M dwarfs and three wide-binary systems observed in the infrared J-band. The absence of large molecular contributions allow for a precise continuum placement. We derive metallicities based on the best fit synthetic spectra to the observed spectra. To verify the accuracy of the applied atmospheric models and test our synthetic spectrum approach, three binary systems with a K-dwarf primary and an M-dwarf companion were observed and analysed along with the single M dwarfs. We obtain a good agreement between the metallicities derived for the primaries and secondaries of our test binaries and thereby confirm the reliability of our method of analysing M dwarfs. Our metallicities agree well with certain earlier determinations, and deviate from others. We conclude that spectroscopic abundance analysis in the J band is a reliable method for establishing the metallicity scale for M dwarfs. We recommend its application to a larger sample covering lower as well as higher metallicities. Further prospects of the method include abundance determinations for individual elements.

title: When Older Adults Use Moodle To Learn Languages...
Creators: name: Wainwright, Jodi Emma
Publisher: name: The Open University
Year: 2023

description: This thesis deals with the underexplored intersection of digital language learning and older adult learners. It is framed within a sociocultural perspective and considers the three dimensions of learning: cognitive, affective and social. The central argument of this thesis is that older adult language learners can benefit from using Moodle as a social learning space that gives them the chance to engage in a community of practice. Moodle also provides pedagogical support, enabling learners to develop their knowledge and skills and use the target language to communicate with others. The overarching question is, what are the challenges and/or rewards for older adults using Moodle to learn languages? Following an interpretive, socio-constructivist paradigm, semi-structured interviews were analysed using inductive methods, and stimulated recall interviews were analysed using deductive analysis methods. These data were supported with extracts from the Moodle platform. The findings showed that digital language learning can be a liberating activity for older adults when part of a blended format. The online format offers compensatory benefits that enable positive outcomes for all learners. Using technologies such as Moodle is a new experience and learners sometimes feel anxious or unsure of their abilities. Through working with peers and/or family members, learners have proved they can overcome this fear and have come to enjoy participating in Moodle. As populations in societies around the world age, there will be an increase in the number of older adults studying foreign languages. This thesis demonstrates how the construction of online social learning spaces for older adult language learners can help by giving them the chance to participate in a community of practice, possibilities for language development, and the freedom to exercise agency.
A comment on the relation between diffraction and entropy

description: Diffraction methods are used to detect atomic order in solids. While uniquely ergodic systems with pure point diffraction have zero entropy, the relation between diffraction and entropy is not as straightforward in general. In particular, there exist families of homometric systems, which are systems sharing the same diffraction, with varying entropy. We summarise the present state of understanding by several characteristic examples.

Optical and Near-IR long-term monitoring of NGC3783 and MR2251-178: evidence for variable near-IR emission from thin accretion discs

description: We present long term near-IR light curves for two nearby AGN: NGC3783 and MR2251-178. The near-IR data are complemented with optical photometry obtained over the same period of time. The light curves in all bands are highly variable and good correlations can be seen between optical and NIR variations. Cross-correlation analysis for NGC 3783 suggests that some disc near-IR emission is present in the J-band flux, while the H and K-bands are dominated by emission from a torus located at the dust sublimation radius. For MR2251-178 the cross-correlation analysis and the optical-near-IR flux-flux plots suggest that the near-IR flux is dominated by disc emission. We model the optical to near-IR Spectral Energy Distributions (SED) of both sources and find that disc flaring might be a necessary modification to the geometry of a thin disc in order to explain the observations. The SED of MR2251-178 gives some indications for the presence of NIR emission from a torus. Finally, we consider the implications of the standard alpha disc model to explain the different origin of the variable NIR emission in these AGN.

description: Electromagnetic tracking (EMT) can partially replace X-ray guidance in minimally invasive procedures, reducing radiation in the OR. However, in this hybrid setting, EMT is disturbed by metallic distortion caused by the X-ray device. We plan to make hybrid navigation clinical reality to reduce radiation exposure for patients and surgeons, by compensating EMT error.

Our online compensation strategy exploits cycle-consistent generative adversarial neural networks (CycleGAN). Positions are translated from various bedside environments to their bench equivalents, by adjusting their z-component. Domain-translated points are fine-tuned on the x–y plane to reduce error in the bench domain. We evaluate our compensation approach in a phantom experiment.

Since the domain-translation approach maps distorted points to their laboratory equivalents, predictions are consistent among different C-arm environments. Error is successfully reduced in all evaluation environments. Our qualitative phantom experiment demonstrates that our approach generalizes well to an unseen C-arm environment. 

Adversarial, cycle-consistent training is an explicable, consistent and thus interpretable approach for online error compensation. Qualitative assessment of EMT error compensation gives a glimpse to the potential of our method for rotational error compensation.

description: Lecture notes for the Brazilian School on Statistical Mechanics, Natal, Brazil, July 2011. The five lectures introduce to the description of entanglement in many-particle systems and review the ground-state entanglement features of standard solvable lattice models. This is done using a thermodynamic formulation in which the eigenvalue spectrum of a certain Hamiltonian determines the entanglement properties. The methods to obtain it are discussed and results, both analytical and numerical, for various cases including time evolution are presented.
