Caring for disabled husbands : wives' perspectives
Creators: name: Kelleher, Anne L.
Publisher: name: University of British Columbia
Year: 2010

description: There is presently an increasing trend towards deinstitutionalization of several different populations, including physically disabled adults. Although a variety of staffed resources provide for alternative care, 'home' and 'family' remain the primary resource in the community based care system. Given that the family of the 1980's has a decreased capacity to care due to such factors as increased mobility and loss of extended family networks we must be concerned with the continued viability of this resource. And, given that 'family’ is often a euphemism for 'nearest female relative' and that women's role in society has changed markedly in recent years the issue of women as caregivers is one of particularly urgent concern. This study is based on extensive interviews with eight women caring for disabled husbands. The interview schedule and methodology facilitated descriptive data regarding caregiving tasks as well as a comprehensive exploration of what was problematic about the day to day reality of caregiving for these women. The data analysis identified struggling with the 'role' of wife-caregiver, isolation and a changed marital dynamic as primary themes in the process of caregiving. This study provides some insight into what is problematic about caregiving for these wives and some suggestions for improving social work practice and providing more effective services in relation to this population.

REMARKS: Rondani (1861g: 389) described both sexes of Sarcophaga setipennis without specifying the exact number of specimens and not giving a range of lengths, but presumably from more than one specimen because he indicated: “ non rara [not rare]”. In his redescription of Sarcophaga setipennis Rondani (1862d: 107) specified the type locality: “ in collibus et planitie agri parmensis [Parmese hills and plains]; in Pedemontio [in Piedmont]”. Pape (1988: 15) designated a lectotype (♂) and paralectotypes (3 ♂♂, 4 ♀♀) but did not mention an additional three specimens: one in the MZUF, one in the MSNC, and one in the MSNPV (all are paralectotypes).

description: Accurate multi-class segmentation is a long-standing challenge in medical imaging, especially in scenarios where classes share strong similarity. Segmenting retinal blood vessels in retinal photographs is one such scenario, in which arteries and veins need to be identified and differentiated from each other and from the background. Intra-segment misclassification, i.e. veins classified as arteries or vice versa, frequently occurs when arteries and veins intersect, whereas in binary retinal vessel segmentation, error rates are much lower. We thus propose a new approach that decomposes multi-class segmentation into multiple binary, followed by a binary-to-multi-class fusion network. The network merges representations of artery, vein, and multi-class feature maps, each of which are supervised by expert vessel annotation in adversarial training. A skip-connection based merging process explicitly maintains class-specific gradients to avoid gradient vanishing in deep layers, to favor the discriminative features. The results show that, our model respectively improves F1-score by 4.4\%, 5.1\%, and 4.2\% compared with three state-of-the-art deep learning based methods on DRIVE-AV, LES-AV, and HRF-AV data sets.

description: We consider a family of models describing the evolution under selection of a population whose dynamics can be related to the propagation of noisy traveling waves. For one particular model, that we shall call the exponential model, the properties of the traveling wave front can be calculated exactly, as well as the statistics of the genealogy of the population. One striking result is that, for this particular model, the genealogical trees have the same statistics as the trees of replicas in the Parisi mean-field theory of spin glasses. We also find that in the exponential model, the coalescence times along these trees grow like the logarithm of the population size. A phenomenological picture of the propagation of wave fronts that we introduced in a previous work, as well as our numerical data, suggest that these statistics remain valid for a larger class of models, while the coalescence times grow like the cube of the logarithm of the population size.

description: A challenge in the Gauss sums factorization scheme is the presence of ghost factors - non-factors that behave similarly to actual factors of an integer - which might lead to the misidentification of non-factors as factors or vice versa, especially in the presence of noise. We investigate Type II ghost factors, which are the class of ghost factors that cannot be suppressed with techniques previously laid out in the literature. The presence of Type II ghost factors and the coherence time of the qubit set an upper limit for the total experiment time, and hence the largest factorizable number with this scheme. Discernability is a figure of merit introduced to characterize this behavior. We introduce preprocessing as a strategy to increase the discernability of a system, and demonstrate the technique with a transmon qubit. This can bring the total experiment time of the system closer to its decoherence limit, and increase the largest factorizable number.

description: A multitype Dawson-Watanabe process is conditioned, in subcritical and critical cases, on non-extinction in the remote future. On every finite time interval, its distribution is absolutely continuous with respect to the law of the unconditioned process. A martingale problem characterization is also given. Several results on the long time behavior of the conditioned mass process|the conditioned multitype Feller branching diffusion are then proved. The general case is first considered, where the mutation matrix which models the interaction between the types, is irreducible. Several two-type models with decomposable mutation matrices are analyzed too.

description: Bio-ethanol as fuel additive suffers of several limitations such as a low energy content per unit volume compared to gasoline, a high water solubility, a great corrosivity. Due to these concerns, it cannot be used in large proportion unless engines are modified [1]. Substitution of ethanol for butanol, in addition to the advantage of a greater calorific value associated to the higher alcohol, can avoid engine modification. Furthermore, it can be transported via the existing gasoline pipelines [1]. Thus, recently, production of fermentation-derived butanol has attracted renewed interest [2]. n-butanol is currently produced by biomass fermentation with Clostridium microorganisms (Acetone Butanol Ethanol or ABE fermentation) on the industrial scale in many industrialized countries [2]. Nevertheless, alternative routes to ABE fermentation are under development.

In this framework, the catalytic upgrade of ethanol into butanol is widely investigated. The process of alcohol dimerization to produce a higher alcohol is known as Guerbet reaction [3]. The reaction is not selective and, in addition to butanol, significant amounts of by-products as acetaldehyde and ethylene can be formed [3]. A suitable combination of both acid and basic sites and the addition of an active metal capable to provide hydrogenation/dehydrogenation properties are considered key-features to drive the reaction path towards the production of butanol.

In this work, a preliminary study of powder catalysts consisting in Ru or Ni dispersed on supports with different acid base character was done in a lab-scale rig which allowed us to select a chemical formulation which will be reproduced as catalytic pellets to be used in a pre-pilot scale rig. The best performance was obtained with 1%Ni/MgO powder catalyst. Best operating conditions were also defined. Catalytic pellets were produced using high surface area -Al2O3 commercial pellets as substrate which were coated with MgO by several impregnation cycles before adding nickel. Pellets were physically and chemically characterized to match their properties to those of the corresponding powder catalyst and their catalytic performance were preliminarily verified in the small scale rig before the final use in the large scale plant.

description: We study the properties and the molecular content of the host of a type-Ia supernova (SN1997ey). This z=0.575 host is the brightest submillimetre source of the sample of type-Ia supernova hosts observed at 450um and 850um by Farrah et al.. Observations were performed at IRAM-30m to search for CO(2-1) and CO(3-2) lines in good weather conditions but no signal was detected. The star formation rate cannot exceed 50 M_sol/yr. These negative results are confronted with an optical analysis of a Keck spectrum and other data archives. We reach the conclusion that this galaxy is a late-type system (0.7 L^B_*), with a small residual star-formation activity (0.2 M_sol/yr) detected in the optical. No source of heating (AGN or starburst) is found to explain the submillimetre-continuum flux and the non-CO detection excludes the presence of a large amount of cold gas. We thus suggest that either the star formation activity is hidden in the nucleus (with A_V ~ 4) or this galaxy is passive or anemic and this flux might be associated with a background galaxy.

TYPE LOCALITY: Rossi (1790: 287) gave no type locality in the redescription of Syrphus arcuatus (Linnaeus, 1758), but presumably it is Tuscany (Italy) because the work deals with insects “ in provinciis Florentina et Pisana collegit [collected in provinces of Florence and Pisa]”; “ in Italia centrali … in Italia media et meridionali [central and south Italy]” (Rondani 1845e: 196) [type locality for Chrysotoxum italicum Rondani, 1845].

CURRENT STATUS: junior synonym of Chrysotoxum intermedium Meigen, 1822 (Peck 1988: 60, Belcari et al. 1995a: 9).
REMARKS: Rondani (1845e: 196) proposed Chrysotoxum italicum for Syrphus arcuatus (Linnaeus, 1758) sensu Rossi (1790: 287), which he considered a new species. Rondani referred to Rossi’s redescription of Syrphus arcuatus, which was based on an unspecified number of specimens, and to an unspecified number of specimens in his collection. Therefore, the type material should be in the collections of Rossi and Rondani. According to Poggi & Conci (1996: 100) and Horn et al. (1990: 333) Rossi’s collection should be in the MNHUB. Fourteen syntypes were found in this study. No specimen under the name Syrphus arcuatus is present in the MNHUB (J. Pohl, pers. comm., December 2019).

description: We argue that a superconducting state with a Fermi-surface of Bogoliubov quasiparticles, a Bogoliubov Fermi-surface (BG-FS), can be identified by the dependence of physical quantities on disorder. In particular, we show that a linear dependence of the residual density of states at weak disorder distinguishes a BG-FS state from other nodal superconducting states. We further demonstrate the stability of supercurrent against impurities and a characteristic Drude-like behavior of the optical conductivity. Our results can be directly applied to electron irradiation experiments on candidate materials of BG-FSs, including Sr$_2$RuO$_4$, FeSe$_{1-x}$S$_x$, and UBe$_{13}$.

The process involves the dimerization of ethanol to butanol, generally known as Guerbet reaction. A lab-scale rig for screening catalysts suitably synthesized for this reaction has been developed. Catalysts with different surface properties, as the presence of acid and basic sites, with the possible addition of small amount of an active metal providing hydrogenation/dehydrogenation properties have been prepared.
Random Matrix Model for Eigenvalue Statistics in Random Spin Systems

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)
subject: FOS: Physical sciences

description: We propose a working strategy to describe the eigenvalue statistics of random spin systems along the whole phase diagram with thermal to many-body localization (MBL) transition. Our strategy relies on two random matrix (RM) models with well-defined matrix construction, namely the mixed (Brownian) ensemble and Gaussian $β$ ensemble. We show both RM models are capable of capturing the lowest-order level correlations during the transition, while the deviations become non-negligible when fitting higher-order ones. Specifically, the mixed ensemble will underestimate the longer-range level correlations, while the opposite is true for $β$ ensemble. Strikingly, a simple average of these two models gives nearly perfect description of the eigenvalue statistics at all disorder strengths, even around the critical region, which indicates the interaction range and strength between eigenvalue levels are the two dominant features that are responsible for the phase transition.

description: It has been proposed that paramagnetic materials exhibit a unique thermoelectric effect near the ferromagnetic transition point due to spin fluctuations. This phenomenon is often referred to as paramagnon drag. We calculate the contribution of this paramagnon drag to the Seebeck coefficient microscopically on the basis of the linear response theory. This leed to a general formula for the contribution to the Seebeck coefficient due to the paramagnon drag, and we clarify the conditions in which the Seebeck coefficient enhances near the ferromagnetic transition point for a single-band and isotropic system. Moreover, we calculate the Seebeck coefficients for a band $\varepsilon \propto k^n$ and a mixture of free-electron-like and flat bands.

description: India was under a grave threat from the second wave of the COVID-19 pandemic particularly in the beginning of May 2021. The situation appeared rather gloomy as the number of infected individuals/active cases had increased alarmingly during the months of May and June 2021 compared to the first wave peak. Indian government/state governments have been implementing various control measures such as lock-downs, setting up new hospitals, and putting travel restrictions at various stages to lighten the virus spread from the initial outbreak of the pandemic. Recently, we have studied the susceptible-exposed-infectious-removed(SEIR) dynamic modelling of the epidemic evolution of COVID-19 in India with the help of appropriate parameters quantifying the various governmental actions and the intensity of individual reactions. Our analysis had predicted the scenario of the first wave quite well. In this present article, we extend our analysis to estimate and analyze the number of infected individuals during the second wave of COVID-19 in India with the help of the above SEIR model. Our findings show that the people's individual effort along with governmental actions such as implementations of curfews, accelerated vaccine strategy are the most important factors to control the pandemic in the present situation and in the future.

description: We developed recently [A. Ferté, et al., J. Phys. Chem. Lett. 11, 4359 (2020)] a method to compute single site double core hole (ssDCH or K$^{-2}$) spectra. We refer to that method as NOTA+CIPSI. In the present paper this method is applied to the O K$^{-2}$ spectrum of the CO$_2$ molecule, and we use this as an example to discuss in detail its convergence properties. Using this approach, a theoretical spectra in excellent agreement with the experimental one is obtained. Thanks to a thorough interpretation of the shake-up states responsible for the main satellite peaks and with the help of a comparison with the O K$^{-2}$ spectrum of CO, we can highlight the clear signature of the two non equivalent carbon oxygen bonds in the oxygen ssDCH CO$_2$ dication.

description: This paper describes the workspace and the inverse and direct kinematic analysis of the VERNE machine, a serial/parallel 5-axis machine tool designed by Fatronik for IRCCyN. This machine is composed of a three-degree-of-freedom (DOF) parallel module and a two-DOF serial tilting table. The parallel module consists of a moving platform that is connected to a fixed base by three non-identical legs. This feature involves (i) a simultaneous combination of rotation and translation for the moving platform, which is balanced by the tilting table and (ii) workspace whose shape and volume vary as a function of the tool length. This paper summarizes results obtained in the context of the European projects NEXT ("Next Generation of Productions Systems").

description: In this thesis, a transfer function-based load model is determined for commercial and industrial load. This model is derived from the composite load model which consist of an induction motor and static load. This developed model is compared to composite load model by considering two cases: 1) a small motor composition load or commercial load and 2) higher motor composition load or industrial load. The research is conducted through MATLAB/Simulink simulation. In order to compare the dynamic response of developed model, a comparative study has been done between the two models. In addition, the influence of voltage and frequency dependency terms on the overall model accuracy for developed model has been evaluated through several case studies considering both voltage and frequency dependency disturbances. A short-term load forecast model is developed for an electrically heated house. This research work is based on experimental data collected by installing current sensors in a house in St. Johns, Newfoundland, Canada. The data was collected for three years and only one-year data is used for this model. The model is based on Recurrent Neural Network (RNN) with wavelet transform. The proposed model is verified by comparing other developed models in the literature through MATLAB deep learning toolbox and wavelet toolbox. The proposed model can more accurately forecast the load.

description: Psychische Auffälligkeiten zählen zu den häufigsten Belastungen im Kindes- und Jugendalter. Psychosoziale Ressourcen können einen protektiven Effekt zur Verhinderung ihrer Entstehung und Verminderung ihrer Ausprägungen haben. Dieser Zusammenhang wird hier nach sozialem Status bei 11- bis 17-Jährigen untersucht. Als Datengrundlage dient die zweite Folgeerhebung der Studie zur Gesundheit von Kindern und Jugendlichen in Deutschland (KiGGS Welle 2, 2014 – 2017). Psychische Auffälligkeiten wurden über Strengths and Difficulties Questionnaires erhoben; psychosoziale Ressourcen über Selbstangaben zu personalen, familiären und sozialen Ressourcen; der Sozialstatus über einen mehrdimensionalen Index, der auf Angaben der Eltern zu Bildung, beruflicher Stellung und Einkommen basiert. Die Analysen zeigen, dass 11- bis 17-Jährige, die über psychosoziale Ressourcen verfügen, seltener psychisch auffällig sind (weitgehend unabhängig von ihrem sozialen Status) und dass ein niedriger Sozialstatus häufiger mit psychischen Auffälligkeiten assoziiert ist als ein höherer. Auch die Verteilung der Ressourcen zeigt Unterschiede zuungunsten derer aus sozial schlechter gestellten Familien. Die Ergebnisse unterstreichen damit die Bedeutung von Maßnahmen der Prävention und Gesundheitsförderung, die auf die Stärkung von Ressourcen zielen. Die Maßnahmen sollten zur gesundheitlichen Chancengerechtigkeit beitragen, indem sie auf die Bedarfe benachteiligter Bevölkerungsgruppen ausgerichtet werden.

description: Quantum computing has been attracting tremendous efforts in recent years. One prominent application is to perform quantum simulations of electron correlations in large molecules and solid-state materials, where orbital degrees of freedom are crucial to quantitatively model electronic properties. Electron orbitals unlike quantum spins obey crystal symmetries, making the atomic orbital in optical lattices a natural candidate to emulate electron orbitals. Here, we construct atom-orbital qubits by manipulating $s$- and $d$-orbitals of atomic Bose-Einstein condensation in an optical lattice. Noise-resilient quantum gate operations are achieved by performing holonomic quantum control, which admits geometrical protection. We find it is critical to eliminate the orbital leakage error in the system. The gate robustness is tested by varying the intensity of the laser forming the lattice. Our work opens up wide opportunities for atom-orbital based quantum information processing, of vital importance to programmable quantum simulations of multi-orbital physics in molecules and quantum materials.

description: Residual wavefront errors in optical elements limit the performance of coronagraphs. To improve their efficiency, different types of devices have been proposed to correct or calibrate these errors. In this paper, we study one of these techniques proposed by Baudoz et al. 2006 and called Self-Coherent Camera (SCC). The principle of this instrument is based on the lack of coherence between the stellar light and the planet that is searched for. After recalling the principle of the SCC, we simulate its performance under realistic conditions and compare it with the performance of differential imaging.

Coalition Games with Cooperative Transmission: A Cure for the Curse of Boundary Nodes in Selfish Packet-Forwarding Wireless Networks

description: In wireless packet-forwarding networks with selfish nodes, applications of a repeated game can induce the nodes to forward each others' packets, so that the network performance can be improved. However, the nodes on the boundary of such networks cannot benefit from this strategy, as the other nodes do not depend on them. This problem is sometimes known as the curse of the boundary nodes. To overcome this problem, an approach based on coalition games is proposed, in which the boundary nodes can use cooperative transmission to help the backbone nodes in the middle of the network. In return, the backbone nodes are willing to forward the boundary nodes' packets. The stability of the coalitions is studied using the concept of a core. Then two types of fairness, namely, the min-max fairness using nucleolus and the average fairness using the Shapley function are investigated. Finally, a protocol is designed using both repeated games and coalition games. Simulation results show how boundary nodes and backbone nodes form coalitions together according to different fairness criteria. The proposed protocol can improve the network connectivity by about 50%, compared with pure repeated game schemes.

description: Two-dimensional crystals with angstrom-scale pores are widely considered as candidates for a next generation of molecular separation technologies aiming to provide extreme, exponentially large selectivity combined with high flow rates. No such pores have been demonstrated experimentally. Here we study gas transport through individual graphene pores created by low intensity exposure to low kV electrons. Helium and hydrogen permeate easily through these pores whereas larger species such as xenon and methane are practically blocked. Permeating gases experience activation barriers that increase quadratically with molecules' kinetic diameter, and the effective diameter of the created pores is estimated as ~2 angstroms, about one missing carbon ring. Our work reveals stringent conditions for achieving the long sought-after exponential selectivity using porous two-dimensional membranes and suggests limits on their possible performance.

description: Electrode is one of the most important factor affecting the performance of microbial fuel cell. To study the effect of composite electrodes on MFC, Fe2O3/graphite (F-G) and
MnFe2O4/PANI (M-P) composites were synthesized. Ferric oxide was incorporated with graphite to construct composite electrode. Manganese ferrite nanoparticles synthesized
from co-precipitation method were incorporated on PANI matrix. The spectral characterization of the prepared composites were performed by XRD, FT-IR and UV-
Visible Spectrophotometry. Crystalline structure was observed in case of F-G composite while semi-crystalline structure was observed in M-P composite.Electrochemical characterization of the composites was performed with the help of cyclic voltammetry and capacitance as well as current densities were calculated. Composite electrodes were evaluated for their performance as anode in the microbial fuel cell containing waste water as electrolyte and salt bridge as proton exchange membrane. It was found that both the composite electrodes, F-G with 4:3 ratio of Fe2O3 to graphite as well as M-P with 2:5 ratio of MnFe2O4 to PANI composite electrode, are suitable for MFC operation.

Modelling the energy dependencies of high-frequency QPO in black hole X-ray binaries

description: We model energy dependencies of the quasi periodic oscillations (QPO) in the model of disc epicyclic motions, with X-ray modulation caused by varying relativistic effects. The model was proposed to explain the high frequency QPO observed in X-ray binaries. We consider two specific scenarios for the geometry of accretion flow and spectral formation. Firstly, a standard cold accretion disc with an active X-ray emitting corona is assumed to oscillate. Secondly, only a hot X-ray emitting accretion flow oscillates, while the cold disc is absent at the QPO radius. We find that the QPO spectra are generally similar to the spectrum of radiation emitted at the QPO radius, and they are broadened by the relativistic effects. In particular, the QPO spectrum contains the disc component in the oscillating disc with a corona scenario. We also review the available data on energy dependencies of high frequency QPO, and we point out that they appear to lack the disc component in their energy spectra. This would suggest the hot flow geometry in the spectral states when high frequency QPO are observed.
