description: To investigate the predictive factors associated with physical impairment among older patients with type 2 diabetes mellitus (T2DM) in Japan and to examine the potential impact of physical impairment on patient-reported health outcomes in this population. A cross-sectional analysis was conducted using patient-reported data from the 2012–2014 Japan National Health and Wellness Survey. Physical impairment was measured using the Physical Component Summary (PCS) score of the Short-Form 36-Item Health Survey (SF-36) three-component model (using Japanese norms). Older T2DM patients (≥65 years old; n = 1511) were dichotomized into physically impaired (PCS ≤ 25th percentile; n = 378) and non-physically impaired (PCS > 25th percentile; n = 1133). Work productivity (absenteeism, presenteeism and overall work impairment), activity impairment and healthcare resource utilization were compared between these groups. Age, female sex, low and high body mass index (BMI), diabetes-related complications, cardiovascular events, unawareness of having hypoglycemic events in the past 3 months, and lack of regular exercise were significant factors associated with physical impairment in multivariable analysis. The physically impaired group reported significantly more regular outpatient visits (13.48 vs. 10.16, respectively, p p = .005), greater presenteeism (27.8% vs. 12.2%, p = .001), overall work impairment (30.0% vs. 13.0%, p = .001) and overall activity impairment (39.5% vs. 17.2%, p < .001) than the non-physically-impaired group after adjusting for covariates. This study identified age, BMI, diabetes-related comorbidities, history of cardiovascular events and lack of exercise as key predictors associated with physical impairment in older patients with T2DM in Japan, which predicted low work productivity as well as activity impairment. This study provides support that physical impairment in patients with T2DM may lead to low work productivity and activity impairment.

Subjects: Uncategorized

description: Background: Psychological distress is frequently observed in neurodegenerative diseases (NDDs), including Huntington’s disease (HD), impacting function, quality of life (QOL), caregiver burden, and illness cost. As psychological resilience can protect against negative outcomes and aid in successful adjustment to illness, understanding what enhances psychological resilience allows us to offer support to people with NDDs. In addition, although executive functioning (EF) has been linked to resilience / psychological wellbeing, its psychological distress buffering qualities in HD have not been studied.Literature review: Eighteen articles were reviewed to investigate factors associated with psychological resilience in NDDs. Studies with varied aims and methodologies were found. Resilience factors were divided into core, internal and external categories. Contradicting evidence was found regarding relationships between resilience and physical function. Fatigue appears to be associated with less resilience. Positive associations were found between resilience and mental health and various psychological / QOL factors. Social connectedness and intervention were discovered to be linked to resilience. The evidence for resilience enhancing interventions suggests that resilience can be modified.Research report: This quantitative longitudinal study explored whether EF abilities predict psychological resilience in HD. The secondary aim was to investigate characteristics of the sample and make comparisons between premanifest and manifest HD groups. Enroll-HD study dataset (N=495) was used to run analyses including descriptive statistics, t-tests / Mann-Whitney U tests, Pearson correlation, and multiple regression. Less EF related problem behaviours were found to predict higher psychological resilience. Less psychological distress, lower BMI and non-smoking were also found to predict higher resilience. The sample had clinically relevant levels of depression/anxiety and physical/functional impairment. The pre-manifest HD group was significantly less impaired than the manifest group in all domains.Critical appraisal: The research process, learning points, implications, and limitations were considered.

description: Objective: As part of the risk management plan in Europe, this study was conducted to characterize drug utilization patterns of Seasonique, a 91-day extended levonorgestrel-containing combined oral contraceptive (COCLNG). Methods: A retrospective observational study was conducted in France, Italy and Belgium using electronic medical record databases obtained from general practitioners (GPs) in all participating countries and gynecologists in France from 2015-2018. The study population included women receiving ≥1 prescription of 91-day COCLNG during the study period. Prescribing patterns of 91-day COCLNG were examined including: (1) treatment duration; (2) indication; (3) use of combined oral contraceptive (COC) before 91-day COCLNG initiation; and (4) switch from and to combined hormonal contraceptives (CHC) or other contraceptives. Results: A total of 235, 220, 207 and 659 women using 91-day COCLNG were identified in French, Italian and Belgian GP and French gynecologist databases, respectively. Across databases, 46%-76% of women were prescribed a single 91-day COCLNG prescription and median treatment duration ranged from 3-6 months. The most common indication was contraception (42%-81%), followed by menstrual migraines (2%-14%). Use of COC during the six months prior to 91-day COCLNG initiation was 14% across GP databases, but was lower (8%) in the French gynecologist database. The frequency of switching from 91-day COCLNG to CHCs or other contraceptives was generally low (5%-12%), with the highest proportion being among patients of French gynecologists. Conclusions: Findings indicate that 91-day COCLNG was prescribed for relatively short durations and predominantly as indicated for contraception. Most results were comparable across all participating countries.

description: To characterize burden of migraine in prevention-eligible patients compared with prevention non-eligible patients in the United States (US). Receipt of preventive therapy was also examined among prevention-eligible patients. This retrospective study utilized data from the 2017 US National Health and Wellness Survey linked with medical and pharmacy claims. Patients aged ≥18 years who self-reported experiencing migraine and had confirmed evidence of migraine (≥1 medical or pharmacy claim) were included. Prevention eligibility was based on number of headache days in the past 30 days (prevention-eligible: ≥4 and prevention non-eligible: <4). Descriptive statistics summarized study variables; bivariate and multivariable analyses were conducted to examine the association of prevention-eligibility status with outcomes. Analyses included 450 patients, 291 (65%) prevention-eligible, and of these 56 (19%) received preventive therapy. Overall, patients were 42.98 ± 14.51 years old; 84% were female. Prevention-eligible patients reported significantly more migraine headache days in the past 6 months (29.27 ± 37.96 vs. 8.61 ± 7.88), had lower mental component summary scores (35.80 ± 2.73 vs. 37.90 ± 2.96), and more presenteeism (47.30 ± 2.98% vs. 37.90 ± 2.60%), overall work impairment (46.30 ± 2.87% vs. 37.90 ± 2.55%) and activity days missed due to migraine (8.16 ± 3.05 vs. 3.82 ± 1.58) than prevention non-eligible patients (all pp=.002) and activity days lost due to migraine (18.39 ± 28.08 vs. 10.69 ± 21.43, p=.015) than those not receiving preventive therapy. Prevention-eligible patients experience greater burden due to migraine, including more headache days, worse health-related quality-of-life, and greater work and activity impairment than prevention non-eligible patients.
A Dog’s Life: An Interdisciplinary Study of Human-Animal Relationships in Roman Britain

description: Dogs were a key animal in the Roman Empire, appearing in numerous texts, art and artefacts. Newly conquered provinces were affected by this enthusiasm, showing abrupt change in the types of dogs kept, with 'dwarf' dogs appearing for the first time (Bartosiewicz 2010; Colominas 2016). How underlying attitudes changed is a question that has been asked of other aspects of provincial Roman life. This includes new rituals, buildings and diets (King 1999b; 2001; Mattingly 2011: 223-228), but rarely interactions with live animals, despite their capacity to influence human society.Previous study examined single burials, selected only one attribute for study (Baxter 2006; Clark 1995; Harcourt 1974; MacKinnon and Belanger 2006), or were limited by poor recording in published reports (MacKinnon 2010a). To avoid this problem, I chose 85 skeletons from Iron Age and Roman Britain to analyse directly. A purpose-built ‘biography’ system brought several types of analysis, including pathology, together to track the lives and deaths of each dog. I also collected a background dataset from published reports and databases.Universally found across Britain, only a slight preference for canines was found on Southern, urban and military sites. The skeletal evidence indicated that traumatic and age-related lesions were equally common before and after the Conquest of AD43, suggesting continuity in how dogs were treated day-to-day. Yet congenital conditions, such as dwarfism and dental crowding, rose dramatically during the Roman occupation. New genetic stock was likely imported into Britain.Exploring these skeletons as individual biographies revealed the stories of dogs that were abused, cared for, and changed the lives of the humans around them. Ultimately, dogs have been an excellent ‘case animal’ to map cultural transformation in Roman Britain, and an indicator of where old ideas prevailed despite new dogs. Or perhaps the conquerors and conquered were not so different in this regard.
Fractional dynamics in nonlinear magnetic metamaterials

description: We examine the existence of nonlinear modes and their temporal dynamics, in arrays of split-ring resonators, using a fractional extension of the Laplacian in the evolution equation. We find a closed-form expression for the dispersion relation as a function of the fractional exponent as well as an exact expression for the critical coupling between rings, beyond which no fractional magnetoinductive wave can exist. We also find the low-lying families of bulk and surface nonlinear modes and their bifurcation diagrams. Here the phenomenology is similar for all exponents and resembles what has been observed in other discrete evolution equations, such as the DNLS. The propagation of an initially localized magnetic excitation is always ballistic, with a `speed' that is computed in exact form as a function of the fractional exponent. For a given exponent, it increases with an increase in coupling up to a critical coupling value, beyond which the ballistic speed could diverge inside the fractional interval $[0,1]$. Examination of the modulational instability shows that it tends to increase with an increase in the fractional exponent, where the decay proceeds via the formation of filamentary structures that merge eventually and form pure radiation. The dynamical selftrapping around an initially localized excitation increases with the fractional exponent, but it also shows a degree of trapping in the linear limit. This trapping increases with a decrease in the exponent and can be explained by near-degeneracy considerations.

description: We present a plane wave/pseudopotential implementation of the method to calculate electron transport properties of nanostructures. The conductance is calculated via the Landauer formula within formalism of Green's functions. Nonorthogonal Wannier-type atomic orbitals are obtained by the sequential unitary rotations of virtual and occupied Kohn-Sham orbitals, which is followed by two-step variational localization. We use these non-orthogonal Wannier type atomic orbitals to partition the Kohn-Sham Hamiltonian into electrode-contact-electrode submatrices. The electrode parts of the system are modeled by two metal clusters with additional Lorentzian broadening of discrete energy levels. We examined our implementation by modeling the transport properties of Na atomic wires. Our results indicate that with the appropriate level broadening the small cluster model for contacts reproduces odd-even oscillations of the conductance as a function of the nanowire length.

description: In the sentiment attitude extraction task, the aim is to identify <> -- sentiment relations between entities mentioned in text. In this paper, we provide a study on attention-based context encoders in the sentiment attitude extraction task. For this task, we adapt attentive context encoders of two types: (1) feature-based; (2) self-based. In our study, we utilize the corpus of Russian analytical texts RuSentRel and automatically constructed news collection RuAttitudes for enriching the training set. We consider the problem of attitude extraction as two-class (positive, negative) and three-class (positive, negative, neutral) classification tasks for whole documents. Our experiments with the RuSentRel corpus show that the three-class classification models, which employ the RuAttitudes corpus for training, result in 10% increase and extra 3% by F1, when model architectures include the attention mechanism. We also provide the analysis of attention weight distributions in dependence on the term type.

description: We consider the small-volume dynamics of nonsupersymmetric orbifold and orientifold field theories defined on a three-torus, in a test of the claimed planar equivalence between these models and appropriate supersymmetric ``parent models". We study one-loop effective potentials over the moduli space of flat connections and find that planar equivalence is preserved for suitable averages over the moduli space. On the other hand, strong nonlinear effects produce local violations of planar equivalence at special points of moduli space. In the case of orbifold models, these effects show that the "twisted" sector dominates the low-energy dynamics.

Is FIRST J102347.6+003841 Really a Cataclysmic Binary?

description: The radio source FIRST J102347.6+003841 was presented as the first radio-selected cataclysmic. In the discovery paper, Bond et al. (2002) show a spectrum consistent with a magnetic AM Her-type system and a light curve with rapid, irregular flickering. In contrast, Woudt, Warner, and Pretorius (2004) found a smoothly-varying light curve with a period near 4.75 h and one minimum per orbit, indicating a dramatic change. We present time-resolved spectra showing a superficially normal, mid-G type photosphere, with no detectable emission lines. The absorption-line radial velocity varies sinusoidally, with semi-amplitude 268 +- 4 km/s, on the orbital period, which is refined to 0.198094(2) d. At this orbital period the secondary's spectral type is atypically early, suggesting an unusual evolutionary history. We also obtained BVI photometry around the orbit. The light curve resembles that given by Woudt et al., and the color modulation is consistent with a heating effect. A simple illumination model matches the observations strikingly well with a Roche-lobe filling secondary near 5650 kelvin being illuminated by a primary giving out around 2 solar luminosities. The modest amplitude of the observed modulation constrains the orbital inclination to be less than about 55 deg, unless the gravity darkening is artificially reduced. The resulting primary star mass is above the Chandrasekhar limit (assuming conventional gravity darkening). We examine the possibility that the compact object in this system is not a white dwarf, in which case this is not actually a cataclysmic variable. On close examination, FIRST J102347.6+003841 defies easy classification.

description: The Prescription Opioid Misuse and Abuse Questionnaire was developed to identify prescription opioid abuse and misuse among patients with chronic pain, however evidence of construct validity and reproducibility is needed. Chronic pain patients were recruited from five Department of Defense Military Health System clinics across the United States. Construct validity was examined using subjective clinician-reported and patient-reported measures as well as objective information (e.g., hair/urine drug screens and electronic medical records). Test-retest reliability was assessed across 2-time points among a subgroup of patients with stable chronic pain. Of 3,263 screened patients, 938 (28.7%) met eligibility and were enrolled; 809 (86.2%) completed the Prescription Opioid Misuse and Abuse Questionnaire. Construct validity was supported by comparison to other validated questionnaires and hair and urine screens which yielded high agreements with patient reports on the Prescription Opioid Misuse and Abuse Questionnaire. Electronic medical record data supported patients’ Prescription Opioid Misuse and Abuse Questionnaire responses regarding physician and emergency room visits and opioid refills. The Prescription Opioid Misuse and Abuse Questionnaire had excellent test-retest reliability; the percentage agreement between the two Prescription Opioid Misuse and Abuse Questionnaire administrations was high (>90%) for most questions. Results suggest that the Prescription Opioid Misuse and Abuse Questionnaire is a valid and reproducible tool that can be used to assess the presence of prescription opioid misuse and abuse among patients with chronic pain.

description: Difficulties arise when conceptual modeling lacks ontological clarity and rigorous definitions, which is especially the case in the relationship construct. Evidence shows that use of relationships is often problematic when it comes to communicating the form of meaning of an application domain. Research on this topic is important because relationships are central to a number of approaches and commonly used by practitioners. In this paper, we study the notion of relation or relationship in the context of conceptual modeling. Specifically, we focus on the notion of relationship used in the entity-relationship (ER) model. The ER model is scrutinized through a new form of conceptual modeling called the thinging machine (TM) to pursue further understanding of the semantics of the relationship concept. The ER model is composed of three fundamental categories (i.e., entity, relationship and attribute), whereas TM is built from one ontological category called the thing/machine (thimac). Several ER diagrams are re-casted as TM diagrams, creating a categorical collision with interesting implications regarding the status of the conception of relationship in a conceptual model. The re-modeling shows that the relational construct is dissipated into TM flows of things and chronology of events.

Seniors' perceptions of respectful nursing care during admission to acute care psychiatric units
Creators: name: Dawson, Thomas Peter
Publisher: name: University of British Columbia
Year: 2009

description: Seniors who have a mental illness are a particularly vulnerable population. Not only do they have to cope with the incapacities caused by their mental illness but may also suffer societal discrimination because of their age and being mentally ill. These two forms of discrimination are known as ageism and stigma of mental illness respectively. Both of these two phenomena devalue a person and create feelings of low self-worth. The opposite however, can be attributed to respect, which bestows value on the person. It is therefore, reasonable to speculate that respectful care may counter the negativities of discrimination and thus play an important part in promoting health in mentally ill seniors. This qualitative study explored whether seniors who were admitted to an acute psychiatric unit received respectful care from nurses and what the indicators of respectful care were for these seniors. Semi-structured interviews were conducted with five seniors who had experienced an admission on an acute psychiatric unit. Interpretative analysis was used to identify common themes in the participants' descriptions of respectful nursing care. The findings suggested that all five participants felt they received respectful nursing care; no incidents of disrespectful nursing care were identified by the participants. Four themes relating to respectful care emerged from the findings. The first three themes related to indicators of respectful care: courteousness, attentiveness to patients' needs and treating patients as people. These three themes appeared to acknowledge and sustain the participants' individuality. Participants felt that nurses displayed genuine interest in them as people while being attentive to their needs. A fourth theme, which appeared to be an antagonist to respect, was conceptualized as "too busy"; participants described how indicators of respect diminished during times when the nurses' workload appeared to increase. Participants did not blame nurses for the reduction of respectful care during these busy periods. Recommendations for nursing practice, education, policy and research are described in the final chapter.

description: We study the environmental dependence of the formation epoch of dark matter haloes in the Millennium Simulation: a ten billion particle N-body simulation of standard LambdaCDM cosmology. A sensitive test of this dependence - the marked correlation function - reveals highly significant evidence that haloes of a given mass form earlier in denser regions. We define a marked cross-correlation function, which helps quantify how this effect depends upon the choice of the halo population used to define the environment. The mean halo formation redshift as a function of the local overdensity in dark matter is also well determined, and we see an especially clear dependence for galaxy-sized haloes. This contradicts one of the basic predictions of the excursion set model of structure formation, even though we see that this theory predicts other features of the distribution of halo formation epochs rather well. It also invalidates an assumption usually employed in the popular halo, or HOD, models of galaxy clustering, namely that the distribution of halo properties is a function of halo mass but not of halo environment.

description: Introduction: Phenylketonuria (PKU) is a rare autosomal recessive disorder caused by a deficiency of phenylalanine hydroxylase (PAH). Its prevalence is estimated to be 1:10,000 in Europe. PKU is the commonest congenital inborn error of metabolism. The aim of our study was to investigate the characteristics of clinical practice in relation to PKU in Italy, in order to raise awareness about the current management and therapeutic approaches adopted. Methods: Six Italian experts conducted a systematic literature review as well as an internal survey to investigate the relevant clinical aspects. Collectively, the expert panel managed a total of 678 PKU patients treated in the early stages of the condition over a 16-year period across six centers. Results: The management of PKU varied markedly between centers, with differences in the composition of the multidisciplinary team, dietary treatments, compliance and adherence to management, tetrahydrobiopterin use, and patient follow-up. Patients were mostly managed by a pediatric reference center from the initial PKU diagnosis during newborn screening until adulthood, without transition to a specialized adult clinician. Fogginess, concentration reduction, low attention, anxiety, irritability, memory deficit, headache, and unstable mood were common features in patients with uncontrolled blood phenylalanine levels (generally above 600 µmol/L). Conclusion: A homogeneous and shared approach to the management of PKU patients is important. Our survey demonstrates the current management of PKU in Italy, with the aim of promoting the implementation of therapeutic strategies and follow-up, increased patient compliance and adherence, and the achievement of the phenylalanine level targets recommended by European Union guidelines. Emerging therapies are likely to become a standard treatment for patients unable to comply with diet therapy and maintain their phenylalanine levels below the threshold values.

description: We calculate the spectra of ultra-high-energy cosmic rays (UHECRs) in an explicit top-down model based on the decays of metastable neutral `crypton' states in a flipped SU(5) string model. For each of the eight specific 10th-order superpotential operators that might dominate crypton decays, we calculate the spectra of both protons and photons, using a code incorporating supersymmetric evolution of the injected spectra. For all the decay operators, the total UHECR spectra are compatible with the available data. Also, the fractions of photons are compatible with all the published upper limits, but may be detectable in future experiments.

description: Bitcoin being a safe haven asset is one of the traditional stories in the cryptocurrency community. However, during its existence and relevant presence, i.e. approximately since 2013, there has been no severe situation on the financial markets globally to prove or disprove this story until the COVID-19 pandemics. We study the quantile correlations of Bitcoin and two benchmarks -- S\&P500 and VIX -- and we make comparison with gold as the traditional safe haven asset. The Bitcoin safe haven story is shown and discussed to be unsubstantiated and far-fetched, while gold comes out as a clear winner in this contest.

description: The infrared conductivity of NaxCoO2 is studied as a function of doping and temperature for x between 0.5 and 1. Charge localization in CoO2 layers shows up through a far-infrared peak (FIP) in the infrared conductivity which coexists with a small Drude contribution. Long-range ordering at x = 0.5 is confirmed to create a far-infrared gap, in addition to the FIP. At high x, the formation of a Spin-Density Wave reported below 22 K dramatically shifts the FIP to higher energy when x is incommensurate with the lattice, indicating an abrupt deepening of the localizing potential. The in-plane E1u phonon lifetime is shown to be sensitive to both "freezing" and ordering of the mobile Na+ ions. A comparison with the behavior of the FIP shows that such "freezing" is not the only origin of charge localization in the CoO layers.

The effect of iron and light co-limitation on the oceanic diatom : Pseudo-nitzshia granii

Publisher: name: University of British Columbia

description: Light and iron (Fe) Co-limitation occur in temperate, Fe-limited regions in seasons where days are short and the mixed layer is deeper than the euophotic zone. In the first part of this study, the effect of light and Fe co-limitation on Pseudo-nitzschia granii isolated from the NE Subarctic Pacific was investigated. This was one of the first studies to investigate the effect of Fe and light on the physiology of oceanic, pennate diatoms in artificial seawater. Fe-limited P. granii grew at slower rates than Fe-replete cells, and the former showed signs of chlorosis and silica deficiency. P. granii was efficient at utilizing light, especially low light. Light and Fe were found to affect different aspects of photosynthesis. Whereas Fe affected the quantum yield of photosynthesis, light affected photochemical efficiency. Despite low growth rates, P. granii was able to survive and grow under Fe-limitation. This was possibly because Fe limitation increased the activity of non-photochemical quenching mechanisms, allowing the cells protection against photodamage. Overall, growth rates were directly related to the rate of linear electron transport through the cells. In the second part of this thesis, interaction of light and temperature on the physiology of P. granii was investigated. Studies on the combined effects of light and temperature, especially in temperate phytoplankton, are rare. Both light and temperature were found to influence growth rates. Temperature dependency decreased with decreasing light. Cellular chlorophyll displayed a modal response to temperature and light. Photosynthetic yield and efficiency were generally depressed at low and high temperatures. Unlike in green algae and some cyanobacteria, low-temperature acclimation in P. granii was not similar to high light acclimation.

description: Let A and B be subsets of Z/pZ such that |A+B| < |A|+|B|+2. We prove that, if |A|>3, |B|>4, |A+B| 52, then A and B are included in arithmetic progressions with the same difference and of size |A|+2 and |B|+2 respectively. This extends the well-known theorem of Vosper and a recent result of Rodseth and one of the present authors.

description: Today, brushless DC motors (BLDCM) have been used in many applications replacing to brushed DC motors. Compared to brushed DC motors, BLDCM offer improved reliability, longer life, smaller size, and lower weight. Besides, BLDCM have become more popular in applications where efficiency is a critical concern and, generally speaking, a BLDCM is considered to be a high-performance motor capable of providing large amounts of torque over a wide speed range. In this paper, a research on sensorless control method which can drive a BLDCM smoothly from standstill to high speeds without position or speed sensors is carried out. Initial rotor position as well as speed of motor at a low speed range is estimated based on the inductance variation principle while at higher speed, the back EMF technique is applied. This sensorless control algorithm is modeled and simulated with MATLAB/SIMULINK software to verify the abilities of the method. The drive control scheme has been implemented on a single-chip controller (STM32F103) and experimental results reveal that the control procedure can work smoothly.

description: Considering Ginsparg-Wilson type fermions dynamically in lattice QCD simulations is a challenging task. The hope is to be able to approach smaller pion masses and to eventually reach physical situations. The price to pay is substantially higher computational costs. Here we discuss first results of a dynamical implementation of the so-called Chirally Improved Fermions, a Dirac operator that obeys the Ginsparg-Wilson condition approximately. The simulation is for two species of mass-degenerate quarks on 12^3x24 lattices with spatial size up to 1.55 fm. Implementation of the Hybrid Monte-Carlo algorithm and an analysis of the results are presented.

description: We discuss the cosmological amplification of tensor perturbations in a simple example of brane-world scenario, in which massless gravitons are localized on a higher-dimensional Kasner-like brane embedded in a bulk AdS background. Particular attention is paid to the canonical normalization of the quadratic action describing the massless and massive vacuum quantum fluctuations, and to the exact mass-dependence of the amplitude of massive fluctuations on the brane. The perturbation equations can be separated. In contrast to de Sitter models of brane inflation, we find no mass gap in the spectrum and no enhancement for massless modes at high curvature. The massive modes can be amplified, with mass-dependent amplitudes, even during inflation and in the absence of any mode-mixing effect.

description: We present archival high resolution X-ray imaging observations of 25 nearby LINERs observed by ACIS on board Chandra. This sample builds on our previously published proprietary and archival X-ray observations, and includes the complete set of LINERs with published black hole masses and FIR luminosities that have been observed by Chandra. Of the 82 LINERs observed by Chandra, 41 (50%) display hard nuclear cores consistent with an AGN. The nuclear 2-10 keV luminosities of these AGN-LINERs range from ~ 2 X 10^38 ergs s^-1 to ~ 1 X 10^44 ergs s^-1. Reinforcing our previous work, we find a significant correlation between the Eddington ratio, L bol/LEdd, and the far-IR (FIR) luminosity, LFIR, as well as the IR brightness ratio, LFIR/LB in the host galaxy of AGN-LINERs that extends over seven orders of magnitude in Lbol/LEdd. Combining our AGN-LINER sample with galaxies from other AGN subclasses, we find that this correlation is reinforced in the full sample of 129 AGN, extending over almost nine orders of magnitude in Lbol/LEdd. Using archival and previously published observations of the 6.2 mm PAH feature from the Infrared Space Observatory (ISO), we find that it is unlikely that dust heating by the AGN dominates the FIR luminosity in our sample of AGN. Our results may therefore imply a fundamental link between the mass accretion rate (Mdot), as measured by the Eddington ratio, and the star formation rate (SFR), as measured by the FIR luminosity.

description: Purpose. Needle placement is a challenging problem for applications such as biopsy or brachytherapy. Tip force sensing can provide valuable feedback for needle navigation inside the tissue. For this purpose, fiber-optical sensors can be directly integrated into the needle tip. Optical coherence tomography (OCT) can be used to image tissue. Here, we study how to calibrate OCT to sense forces, e.g. during robotic needle placement. Methods. We investigate whether using raw spectral OCT data without a typical image reconstruction can improve a deep learning-based calibration between optical signal and forces. For this purpose, we consider three different needles with a new, more robust design which are calibrated using convolutional neural networks (CNNs). We compare training the CNNs with the raw OCT signal and the reconstructed depth profiles. Results. We find that using raw data as an input for the largest CNN model outperforms the use of reconstructed data with a mean absolute error of 5.81 mN compared to 8.04 mN. Conclusions. We find that deep learning with raw spectral OCT data can improve learning for the task of force estimation. Our needle design and calibration approach constitute a very accurate fiber-optical sensor for measuring forces at the needle tip.
