description: The conversion of ultracold atoms to molecules via a magnetic Feshbach resonance with a sinusoidal modulation of the field is studied. Different practical realizations of this method in Bose atomic gases are analyzed. Our model incorporates many-body effects through an effective reduction of the complete microscopic dynamics. Moreover, we simulate the experimental conditions corresponding to the preparation of the system as a thermal gas and as a condensate. Some of the experimental findings are clarified. The origin of the observed dependence of the production efficiency on the frequency, amplitude, and application time of the magnetic modulation is elucidated. Our results uncover also the role of the atomic density in the dynamics, specifically, in the observed saturation of the atom-molecule conversion process.

description: In this paper, we study regularity of solutions to linear evolution equations of the form $dX+AXdt=F(t)dt$ in a Banach space $H$, where $A$ is a sectorial operator in $H$ and $A^{-α} F \, (α>0)$ belongs to a weighted Hölder continuous function space. Similar results are obtained for linear evolution equations with additive noise of the form $dX+AXdt=F(t)dt+G(t)dW(t)$ in a separable Hilbert space $H$, where $W(t)$ is a cylindrical Wiener process. Our results are applied to a model arising in neurophysiology, which has been proposed by Walsh \cite{Walsh}.

description: Objective Transclival endoscopic endonasal approaches to the skull base are novel with few published cases.We report our institution’s experience with this technique and discuss outcomes according to the clival region involved. Design Retrospective case series. Setting Tertiary care academic medical center Participants All patients who underwent endoscopic endonasal transclival approaches for skull base lesions from 2008 to 2012. Main Outcome Measures Pathologies encountered, mean intraoperative time, intraoperative complications, gross total resection, intraoperative cerebrospinal fluid (CSF) leak, postoperative CSF leak, postoperative complications, and postoperative clinical course. Results A total of 49 patients underwent 55 endoscopic endonasal transclival approaches. Pathology included 43 benign and 12 malignant lesions. Mean follow-up was 15.4 months. Mean operative time was 167.9 minutes, with one patient experiencing an intraoperative internal carotid artery injury. Of the 15 cases with intraoperative cerebrospinal fluid (CSF) leaks, 1 developed postoperative CSF leak (6.7%). There were six other postoperative complications: four systemic complications, one case of meningitis, and one retropharyngeal abscess. Gross total resection was achieved for all malignancies approached with curative intent. Conclusions This study provides evidence that endoscopic endonasal transclival approaches are a safe and effective strategy for the surgical management of a variety of benign and malignant lesions.

description: The research project focused on the analysis of the work of Fabio Vacchi, born in Bologna in 1949, one of the most famous living Italian composers performed in Italy and abroad. The research was conducted mainly on the analysis of his musical theatre and in particular on the various stages of gestation of his new Opera ?The Magic Mirror?, libretto by Aldo Nove. This Opera is going to be staged in 2016, based on a heterogeneous writing that involves even the urban vocal style used by rappers. The composer Vacchi used ethnic and folk matrices of the past and the present with reference to areas of the Western repertoire, merging the different materials in a contemporary and personal style. His musical language is communicative, evocative and emotional as consistent and rigorous.

description: This essay investigates one of the most controversial aspects of the relationships between the Italian State and the Regions defined by the italian doctrine as ?contrattazione di legittimit�?, which refers to the negotiation of regional laws in order to overcome the objections of legitimacy raised by the Government. A significant part of the conflicts before the Italian Constitutional Court deals with this aspect which is evident in the numerous decisions with which the Court declares the proceeding or the contested subject matter terminated. This research looks into the ways in which this negotiation takes place highlighting at the same time its main issues. The analysis is also aimed at proposing suitable solutions for a system, like the Italian one, which lacks institutions where the state and the regional legislators can effectively cooperate. In so doing, a moment will be dedicated to the recent attempt of constitutional reform and to its ability to put an end to the ongoing conflicts between State and Regions.
ADAPTIVE AND IMPLICIT ONLINE LEARNING

Year: 2021

description: This thesis is dedicated to the study of online learning algorithms. In particular, after reviewing fundamental concepts in the theory of convex and online linear optimization, we provide a refined analysis of Implicit updates in the framework of Online Mirror Descent. We design a new adaptive algorithm based on it and carefully study its regret bound in the static case, linking it to the variability of the sequence of loss functions. Furthermore, we extend its application to the dynamic setting, studying its dynamic regret. In particular, we show that it achieves the optimal dynamic regret bound, when the quantities of interest are observable or known beforehand. On the other hand, in order to have a fully adaptive algorithm we show how to combine strongly adaptive algorithms with a simple greedy strategy. Finally, we focus on the well known problem of learning with expert advice. We review existing algorithm and describe an existing open problem. We provide some recent results and partial progress on how this problem could be addressed.

description: A dual thermal and electrical stimulator was developed to examine the central pathways that transmit noxious stimuli for intact dentition. This system allows computer-controlled stimulation of the canines of ferrets with either noxious heat or electrical stimuli. A set of in vitro studies demonstrated that the application of thermal stimuli to an intact tooth can produce pulpal temperatures above 43°C, which is perceived as a painful stimulus in humans. In a set of in vivo studies, it was demonstrated that heating an intact tooth at temperatures of at least 40°C, excited trigeminal brainstem neurons. Only 15% of the neurons activated by electrical stimulation responded to noxious heat applied to the canine. Eight of the 23 neurons were classified as nociceptive specific neurons and responded only to noxious stimulation of their cutaneous receptive fields. Fifteen of the 23 neurons were classified as wide dynamic range neurons and responded to both noxious and non-noxious stimulation applied to their cutaneous receptive fields. This new device can accurately deliver both thermal and electrical stimuli to an intact tooth, which allows an evaluation of the central neural circuits that respond to noxious stimulation of the dentition.

description: Precision radial velocities are required to discover and characterize planets orbiting nearby stars. Optical and near infrared spectra that exhibit many hundreds of absorption lines can allow the m/s precision levels required for such work. However, this means that studies have generally focused on solar-type dwarf stars. After the main-sequence, intermediate-mass stars (former A-F stars) expand and rotate slower than their progenitors, thus thousands of narrow absorption lines appear in the optical region, permitting the search for planetary Doppler signals in the data for these types of stars. We present the discovery of two giant planets around the intermediate-mass evolved star HIP65891 and HIP107773. The best Keplerian fit to the HIP65891 and HIP107773 radial velocities leads to the following orbital parameters: P=1084.5 d; m$_b$sin$i$ = 6.0 M$_{jup}$; $e$=0.13 and P=144.3 d; m$_b$sin$i$ = 2.0 M$_{jup}$; $e$=0.09, respectively. In addition, we confirm the planetary nature of the outer object orbiting the giant star HIP67851. The orbital parameters of HIP67851c are: P=2131.8 d, m$_c$sin$i$ = 6.0 M$_{jup}$ and $e$=0.17. With masses of 2.5 M$_\odot$ and 2.4 M$_\odot$ HIP65891 and HIP107773 are two of the most massive stars known to host planets. Additionally, HIP67851 is one of five giant stars that are known to host a planetary system having a close-in planet ($a

description: General relativity (GR) is the current description of gravity in modern physics. One of the cornerstones of GR, as well as Newton's theory of gravity, is the weak equivalence principle (WEP), stating that the trajectory of a freely falling test body is independent of its internal structure and composition. WEP is known to be valid for the normal matter with a high precision. However, due to the rarity of antimatter and weakness of the gravitational forces, the WEP has never been confirmed for antimatter. The current direct bounds on the ratio between the gravitational and inertial masses of the antihydrogen do not rule out a repulsive nature for the antimatter gravity. Here we establish an indirect bound of 0.13% on the difference between the gravitational and inertial masses of the positron (antielectron) from the analysis of synchrotron losses at the Large Electron-Positron collider (LEP). This serves as a confirmation of the conventional gravitational properties of antimatter without common assumptions such as, e.g., coupling of gravity to virtual particles, dynamics of distant astrophysical sources and the nature of absolute gravitational potentials.

description: The influence of a saturable nonlinearity on the modulation instability in oppositely directed coupler in the presence of high-order effects is investigated. By using the standard linear stability analysis, we obtain the instability gain that exhibits a significant change in the bands of instability due to the effects of a saturable nonlinearity. We also show that even in the presence of saturation there is no change in instability gain when we compare the results obtained for both channels not influenced by self-steepening effect or for both channels influenced by self-steepening effect but opposite in sign. Regarding the Raman effect, there is reflection symmetry (asymmetry) to the gain at zero perturbation frequency when the values of the Raman coefficients in each directional coupler are equal and with same (opposite) sign. For the anomalous group velocity dispersion regime we observe that the growth of the saturation parameter is followed by an increase in the null gain region near Ω = 0, enlarging the separation of the instability bands close to this point. Finally, we show that an efficient control of the modulation instability can be realized by adjusting self-steepening effect and intrapulse Raman scattering, even in the presence of a saturable nonlinearity.

description: Comprehensive knowledge of built-in batteries in waste electrical and electronic equipment (WEEE) is required for sound and save WEEE management. However, representative sampling is challenging due to the constantly changing composition of WEEE flows and battery systems. Necessary knowledge, such as methodologically uniform procedures and recommendations for the determination of minimum sample sizes (MSS) for representative results, is missing. The direct consequences are increased sampling efforts, lack of quality-assured data, gaps in the monitoring of battery losses in complementary flows, and impeded quality control of depollution during WEEE treatment. In this study, we provide detailed data sets on built-in batteries in WEEE and propose a non-parametric approach (NPA) to determine MSS. For the pilot dataset, more than 23 Mg WEEE (6500 devices) were sampled, examined for built-in batteries, and classified according to product-specific keys (UNUkeys and BATTkeys). The results show that 21% of the devices had battery compartments, distributed over almost all UNUkeys considered and that only about every third battery was removed prior to treatment. Moreover, the characterization of battery masses (BM) and battery mass shares (BMS) using descriptive statistical analysis showed that neither product- nor battery-specific characteristics are given and that the assumption of (log-)normally distributed data is not generally applicable. Consequently, parametric approaches (PA) to determine the MSS for representative sampling are prone to be biased. The presented NPA for MSS using data-driven simulation (bootstrapping) shows its applicability despite small sample sizes and inconclusive data distribution. If consistently applied, the method presented can be used to optimize future sampling and thus reduce sampling costs and efforts while increasing data quality.

description: Purpose—To assess the prevalence of postdischarge nausea and vomiting (PDNV) after Le Fort I osteotomy with and without the use of a multimodal antiemetic protocol shown to decrease postoperative nausea and vomiting (PONV). Materials and Methods—Consecutive patients undergoing Le Fort I osteotomy with or without additional procedures at a single academic institution formed the intervention cohort for an institutional review board–approved prospective clinical trial with a retrospective comparison group. The intervention cohort was managed with a multimodal antiemetic protocol. The comparison group consisted of consecutive patients who underwent similar surgical procedures at the same institution before protocol implementation. All patients were asked to complete a postdischarge diary documenting the occurrence of nausea and vomiting. Those who completed the diaries were included in this analysis. Data were analyzed with the Fisher exact test and the Wilcoxon rank sum test. A P value less than .05 was considered significant. Results—Diaries were completed by 85% of patients in the intervention group (79 of 93) and 75% of patients in the comparison group (103 of 137). Patients in the intervention (n = 79) and comparison (n = 103) groups were similar in the proportion of patients with validated risk factors for PDNV, including female gender, history of PONV, age younger than 50 years, opioid use in the postanesthesia care unit (PACU), and nausea in the PACU (P = .37). The prevalence of PDNV was unaffected by the antiemetic protocol. After discharge, nausea was reported by 72% of patients in the intervention group and 60% of patients in the comparison group (P = .13) and vomiting was reported by 22% of patients in the intervention group and 29% of patients in the comparison group (P = .40). Conclusion—Modalities that successfully address PONV after Le Fort I osteotomy might fail to affect PDNV, which is prevalent in this population. Future investigation will focus on methods to minimize PDNV.

description: Anthropogenic mineral residues are characterized by their material complexity and heterogeneity, which pose challenges to the chemical analysis of multiple elements. However, creating an urban mine knowledge database requires data using affordable and simple chemical analysis methods, providing accurate and valid results. In this study, we assess the applicability of simplified multi-element chemical analysis methods for two anthropogenic mineral waste matrices: (1) lithium-ion battery ash that was obtained from thermal pre-treatment and (2) rare earth elements (REE)-bearing iron-apatite ore from a Swedish tailing dam. For both samples, simplified methods comprising ‘inhouse’ wet-chemical analysis and energy-dispersive Xray fluorescence (ED-XRF) spectrometry were compared to the results of the developed matrix-specific validated methods. Simplified wet-chemical analyses showed significant differences when compared to the validated method, despite proven internal quality assurance, such as verification of sample homogeneity, precision, and accuracy. Matrix-specific problems, such as incomplete digestion and overlapping spectra due to similar spectral lines (ICP-OES) or element masses (ICP-MS), can result in quadruple overestimations or underestimation by half when compared to the reference value. ED-XRF analysis proved to be applicable as semi-quantitative analysis for elements with mass fractions higher than 1000 ppm and an atomic number between Z 12 and Z 50. For elements with low mass fractions, ED-XRF analysis performed poorly and showed deviations of up to 90 times the validated value. Concerning all the results, we conclude that the characterization of anthropogenic mineral residues is prone to matrix-specific interferences, which have to be addressed with additional quality assurance measures.

description: We have used diffraction gratings to simplify the fabrication, and dramatically increase the atomic collection efficiency, of magneto-optical traps using micro-fabricated optics. The atom number enhancement was mainly due to the increased beam capture volume, afforded by the large area (4cm^2) shallow etch (200nm) binary grating chips. Here we provide a detailed theoretical and experimental investigation of the on-chip magneto-optical trap temperature and density in four different chip geometries using 87Rb, whilst studying effects due to MOT radiation pressure imbalance. With optimal initial MOTs on two of the chips we obtain both large atom number (2x10^7) _and_ sub-Doppler temperatures (50uK) after optical molasses.

description: Objective: Late preterm (LPT) neonates account for over 70% of all preterm births in the US. Approximately 60% of LPT births are the result of non-spontaneous deliveries.The optimal timing of delivery for many obstetric conditions at LPT gestations is unclear, likely resulting in obstetric practice variation. The purpose of this study is to identify variation in the obstetrical management of LPT pregnancies. Study design: We surveyed obstetrical providers in NC identified from NC Medical Board and NC Obstetrical and Gynecological Society membership lists. Participants answered demographic questions and 6 multiple-choice vignettes on management of LPT pregnancies. Result: We obtained 215/859 (29%) completed surveys; 167 (78%) from Obstetrics/Gynecology, 27 (13%) from Maternal-Fetal Medicine, and 21 (10%) from Family Medicine physicians. Overall, we found more agreement on respondents’ management of chorioamnionitis (97% would proceed with delivery), mild preeclampsia (84% would delay delivery/expectantly manage), and fetal growth restriction (80% would delay delivery/expectantly manage). We found less agreement on the management of severe preeclampsia (71% would proceed with delivery), premature preterm rupture of membranes (69% would proceed with delivery), and placenta previa (67% would delay delivery/expectantly manage). Management of LPT pregnancies complicated by PPROM, FGR, and placenta previa vary by specialty. Conclusion: Obstetrical providers report practice variation in the management of LPT pregnancies. Variation might be influenced by provider specialty. The absence of widespread agreement on best practice might be a source of modifiable LPT birth.

description: ABSTRACT. Objective: This study examined relations between children’s susceptibility to alcohol use initiation and parents’ alcohol-specific beliefs, attitudes, and practices and whether these relations vary by parental alcohol use. Method: The sample comprised 1,050 pairs of mothers or mother surrogates and their third-grade children (51.8% female) recruited for a 4-year intervention trial. Families were recruited from school districts located primarily in North Carolina; the school districts provided permission for study recruitment materials to be distributed to families but were not otherwise involved in the research. Data are from the baseline cross-sectional telephone interviews conducted with the mothers and children. Children’s susceptibility to alcohol use initiation is based on child reports, and parental alcohol-specifi c beliefs, attitudes, and practices are based on maternal reports. Results: All parental alcohol socialization attributes were statistically signifi cantly associated as hypothesized with child susceptibility to alcohol use initiation. In the final full model, the mother’s disapproving attitude about child sipping and the interaction between mother–child communication and parental alcohol use frequency were uniquely signifi cantly associated with child susceptibility. Talking with the child about harmful consequences of alcohol use was associated with reduced child susceptibility in families where parents drank alcohol more frequently but had no relationship with child susceptibility in families where parents drank infrequently. Conclusions: The normative interactions that parents have with their elementary school children may inhibit or facilitate children’s susceptibility to alcohol use. To the extent that child susceptibility leads to early onset of use, prevention programs directed at parents to reduce child susceptibility are indicated.

description: Injections of large volumes of water into tight shale reservoirs allows the extraction of oil and gas not previously accessible. This large volume "super" fracking induces damage that allows the oil and/or gas to flow to an extraction well. The purpose of this paper is to provide a model for understanding super fracking. We assume that water is injected from a small spherical cavity into a homogeneous elastic medium. The high pressure of the injected water generates hoop stresses that reactivate natural fractures in the tight shales. These fractures migrate outward as water is added creating a spherical shell of damaged rock. The porosity associated with these fractures is equal to the water volume injected. We obtain an analytic expression for this volume. We apply our model to a typical tight shale reservoir and show that the predicted water volumes are in good agreement with the volumes used in super fracking.

description: Objectives—Decision aids are effective to improve decision-making, yet they are rarely tested in nursing homes (NHs). Study objectives were to 1) examine the feasibility of a Goals of Care (GOC) decision aid for surrogate decision-makers (SDMs) of persons with dementia; and 2) test its effect on quality of communication and decision-making. Design—Pre-post intervention to test a GOC decision aid intervention for SDMs for persons with dementia in NHs. Investigators collected data from reviews of resident health records and interviews with SDMs at baseline and 3-month follow up. Setting—Two NHs in North Carolina. Participants—18 residents who were over 65 years of age, had moderate to severe dementia on the Global Deterioration Scale (GDS=5,6,7), and an English-speaking surrogate decision-maker. Intervention—1) GOC Decision Aid video viewed by the SDM, and 2) a structured care plan meeting between the SDM and interdisciplinary NH team. Measurements—Surrogate knowledge, quality of communication with health care providers, surrogate-provider concordance on goals of care, and palliative care domains addressed in the care plan. Results—89% of the SDMs thought the decision aid was relevant to their needs. After viewing the video decision aid, SDMs increased the number of correct responses on knowledge-based questions (12.5 vs 14.2, P<.001). At 3 months they reported improved quality of communication scores (6.1 vs 6.8, P=.01) and improved concordance on primary goal of care with nursing home team (50% vs 8%, P=.003). The number of palliative care domains addressed in the care plan increased (1.8 vs 4.3, P<.001). Conclusion—The decision-support intervention piloted in this study was feasible and relevant for surrogate decision-makers of persons with advanced dementia in nursing homes, and it improved quality of communication between SDM and NH providers. A larger randomized clinical trial is underway to provide further evidence of the effects of this decision aid intervention.

description: The Green Information Systems research stream was initiated by leading information systems researchers to address climate change through information and communications technology. This paper responds to a call for practical research into the design of information systems that support consumers in their decision making in favour of sustainable products. We apply an exploratory approach to improve understanding of regional trust cues in the energy sector and how these could drive the sector’s decentralisation. We explore the still emerging phenomenon of regional text and imagery on digital user interfaces via a multi-method process including quantitative and qualitative content analysis. Our findings suggest that regional energy providers systematically employ regional textual and pictorial trust cues on their websites. We further lay the ground for future experimental work on this matter by defining terms and concepts and systematically capturing design elements. We outline practical implications for designing user interfaces in the energy sector and discuss how this could drive the sector’s platformisation and sustainabilisation. In addition, we discuss implications for consumers who could become the target of regional washing attempts, in other words providers applying regional cues to create a regional company image in the absence of actual regionality.

description: Congenital ocular toxoplasmosis is a significant cause of blindness. Retinochoroiditis is the most common finding, but other ocular manifestations include microphthalmus, nystagmus, strabismus, and ptosis. The serologic tests and lymphocyte stimulation test are the most useful aids in making the diagnosis. Pyrimethamine, sulfonamides, and corticosteroids are useful to treat active lesions. Primary care physicians, obstetricians, and ophthalmologists may help to prevent transmission of the disease and its serious ocular sequelae.
Tight-binding approach to understand photoelectron intensity from graphene for circularly polarized light

description: We have investigated the effect of imperfect circular polarization on the angle-resolved photoemission spectroscopy signal, using graphene as a prototypical system that can be understood within tight-binding formalism. We found that perfect left- and right-circularly polarized lights give the same photoelectron intensity distribution around a constant energy contour of the graphene $π$ band. On the other hand, upon breaking the purity of the polarization, photoelectron intensity starts to show circular dichroism, which is enhanced with further increasing the imperfection. Our results predict the existence of an additional factor for the circular dichroism observed in the photoemission signal from graphene and hence suggest the importance of experimental conditions to understand circular dichroism observed via photoemission spectroscopy.
On global inverse and implicit functions

description: Since the Hadamard Theorem, several metric and topological conditions have emerged in the literature to date, yielding global inversion and implicit theorems for functions in different settings. Relevant examples are the mappings between infinite-dimensional Banach-Finsler manifolds, which are the focus of this work. Emphasis is given to the nonlinear Fredholm operators of nonnegative index between Banach spaces. The results are based on good local behavior of $f$ at every $x$, namely: $f$ is a local homeomorphism or $f$ is locally equivalent to a projection. The general structure includes a condition that ensures a global property for the fibres of $f$, ideally, expecting to conclude that $f$ is a global diffeomorphism or equivalent to a global projection. A review of such these results and some relationships between different criteria are shown. Also, in this context, a global version of Graves Theorem is obtained.

Recognizing the Incestuous Family
Creators: name: Johnson, Mark S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1983

description: Family physicians are in the best position to diagnose incest because of the nature of their practice. Yet many cases of incest are not recognized by the medical community and many incest victims are thus untreated. There are several behavioral and medical clues to incest, which the family physician needs to know in order to recognize incest early and improve the prognosis. Treatment is directed at the whole family, rather than just the active participants. Further research is needed to improve the application of various treatment modalities.

Comparison of AP Supine vs PA Upright Methods of Chest Roentgenography in Infants and Young Children

description: Various arguments have been advanced for preferring either the AP recumbent projection or the PA upright projection in chest roentgenography of infants and young children. One prominent argument for PA projection is that it shows less magnification.In a search of the literature, no study could be identified that statistically compares the cardiothoracic ratios in a series of patients with simultaneous PA upright and AP supine chest roentgenograms. This study addresses that point and also examines other factors in the two different projections.A survey of pediatric radiology departments in the United States shows an overall preference for the AP supine projection by a factor of 2:1. Statistical analysis of the two methods in this study demonstrates no significant difference in the cardiothoracic ratios. All other factors considered, the authors are of the opinion that the AP supine projection is more desirable in the infant and young child.

description: The combination of plasmonic nanoparticles and graphene enhances the responsivity and spectral selectivity of graphene-based photodetectors. However, the small area of the metal-graphene junction, where the induced electron-hole pairs separate, limits the photoactive region to sub-micron length scales. Here, we couple graphene with a plasmonic grating and exploit the resulting surface plasmon polaritons to deliver the collected photons to the junction region of a metal-graphene-metal photodetector. This results into a 400% enhancement of responsivity and a 1000% increase in photoactive length, combined with tunable spectral selectivity. The interference between surface plasmon polaritons and the incident wave introduces new functionalities, such as light flux attraction or repulsion from the contact edges, enabling the tailored design of the photodetector's spectral response. This architecture can also be used for surface plasmon bio-sensing with direct-electric- readout, eliminating the need of complicated optics.

description: Questo capitolo si occupa della recente crisi finanziaria e del fallito tentativo di cambio di paradigma. Il movimento di protesta mondiale è stato inefficace nel avere un impatto sulle politiche e nel proporre un modello alternativo al capitalismo finanziario. Il movimento cooperativo e quello di protesta hanno molti punti in comune nonostante la mancanza di dialogo tra loro. Il movumento occupy ha bisogno di una alternativa fattibile e un piano di azione pragmatico per rendere la protesta più costruttiva e conseguentemente efficace. Senza una proposta fattibile e robusta, il movimento di protesta è destinato al declino o dovrà reinventarsi in una forma più radicale.
