Origin of photomultiplication in C60 based devices

description: In this manuscript, the origin of the photomultiplication effect was studied in C60 based devices by evaluating the wavelength dependent external and internal quantum efficiencies under various biases. The effect of materials with disordered structures on the photomultiplication effect was determined by intentionally integrating both ordered and disordered material structures into one organic solar cell device with a configuration of indium tin oxide/poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS)∕pentacene∕C60 fullerene/bathocuproine (BCP)/Al. Our results show that both the disordered structure of C60 and the charge trapping effect at the C60∕PEDOT:PSS interface contribute to the photomultiplication effect. By studying the C60-only single layer device, the charge trapping sites are identified to be at the C60 and PEDOT:PSS interface. The interfacial traps behave as an electronic valve that enables a significant increase in electron injection, which causes the photomultiplication phenomena. Quantitative comparisons indicate that photomultiplication induced by C60 disordered structure is much less significant than that by charge trapping at the interface.

description: Recently, electrical bistability was demonstrated in polymer thin films incorporated with metal nanoparticles [J. Ouyang, C. W. Chu, C. R. Szmanda, L. P. Ma, and Y. Yang, Nat. Mater. 3, 918 (2004)]. In this letter, we show the evidence that electrons are the dominant charge carriers in these bistable devices. Direct integration of bistable polymer layer with a light-emitting polymer layer shows a unique light-emitting property modulated by the electrical bistability. A unique negative differential resistance induced by the charged gold nanoparticles is observed due to the charge trapping effect from the nanoparticles when interfaced with the light-emitting layer.

description: Highly efficient white light emission was realized via the partial energy transfer from blue host polyfluorene (PF) to orange light emission dopant rubrene. A more balanced charge transport was achieved by adding an electron transport material, 2-(4-biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole (PBD), into the PF-rubrene system to enhance the electron transportation. Efficiency improvement by as much as a factor of 2 has been observed through the addition of PBD. These devices can easily reach high luminance at low driving voltages, thus achieving high power efficiency at high luminance (14.8, 13.5, and 12.0lm∕W at the luminances of 1000, 2000, and 4000cd/m2, respectively). Therefore, this performance is an important approach toward solid-state lighting application. The enhancement is mainly attributed to three factors: increased electron transport property of the host material, increased photoluminescence quantum efficiency, and the shifting of emission zone away from cathode contact. The reported efficiency is among the highest values reported in the white emission polymer light-emitting diodes.

description: Quaternion-valued wireless communication systems have been studied in the past. Although progress has been made in this promising area, a crucial missing link is lack of effective and efficient quaternion-valued signal processing algorithms for channel equalisation and beamforming. With most recent developments in quaternion-valued signal processing, in this work, we fill the gap to solve the problem and further derive the quaternion-valued Wiener solution for block-based calculation.

description: Accurate color reproduction is important in many applications of 3D printing, from design prototypes to 3D color copies or portraits. Although full color is available via other technologies, multi-jet printers have greater potential for graphical 3D printing, in terms of reproducing complex appearance properties. However, to date these printers cannot produce full color, and doing so poses substantial technical challenges, from the shear amount of data to the translucency of the available color materials. In this paper, we propose an error diffusion halftoning approach to achieve full color with multi-jet printers, which operates on multiple isosurfaces or layers within the object. We propose a novel traversal algorithm for voxel surfaces, which allows the transfer of existing error diffusion algorithms from 2D printing. The resulting prints faithfully reproduce colors, color gradients and fine-scale details.

Influence of composition and heat-treatment on the charge transport properties of poly(3-hexylthiophene) and [6,6]-phenyl C61-butyric acid methyl ester blends

description: Poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61-butyric acid methyl ester (PCBM) blends have been demonstrated to form highly efficient polymer photovoltaic devices. In this letter, the time-of-flight technique is used to investigate the influence of composition and heat treatment on charge transport properties of P3HT and PCBM blends. The transport of electrons and holes both display a transition from dispersive to nondispersive and return to dispersive again as the percentage of PCBM increases. A balanced mobility of both electron and hole is obtained at a composition of 1:1 weight ratio, and it is nearly independent of the electrical field in the range of our test. The increase in carrier mobility is attributed to the formation of a more-ordered structure in the blend. This structural ordering is further enhanced by slowly evaporating the solvent during film formation which results in additional increase in carrier mobility. However, no such effect is observed in thick films (∼200nm), indicating the presence of such high-degree ordering due to heat treatment.

description: We present a unified framework for a number of different ways of failing to generalize properly. During learning, sources of random information contaminate the network, effectively augmenting the training data with random information. The complexity of the function computed is therefore increased, and generalization is degraded. We analyze replicated networks, in which a number of identical networks are independently trained on the same data and their results averaged. We conclude that replication almost always results in a decrease in the expected complexity of the network, and that replication therefore increases expected generalization. Simulations confirming the effect are also presented.

description: In this work we study different classes of effective composite metrics proposed in the context of one-loop quantum corrections in bimetric gravity. For this purpose we consider contributions of the matter loops in form of cosmological constants and potential terms yielding two types of effective composite metrics. This guarantees a nice behaviour at the quantum level. However, the theoretical consistency at the classical level needs to be ensured additionally. It turns out that among all these possible couplings only one unique effective metric survives this criteria at the classical level.

description: We present a microscopic study on the impact of doping on the carrier dynamics in graphene, in particular focusing on its influence on the technologically relevant carrier multiplication in realistic, doped graphene samples. Treating the time- and momentum-resolved carrier-light, carrier-carrier, and carrier-phonon interactions on the same microscopic footing, the appearance of Auger-induced carrier multiplication up to a Fermi level of 300 meV is revealed. Furthermore, we show that doping favors the so-called hot carrier multiplication occurring within one band. Our results are directly compared to recent time-resolved ARPES measurements and exhibit an excellent agreement on the temporal evolution of the hot carrier multiplication for n- and p-doped graphene. The gained insights shed light on the ultrafast carrier dynamics in realistic, doped graphene samples

Compressed Sensing Recovery via Nonconvex Shrinkage Penalties

Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: The $\ell^0$ minimization of compressed sensing is often relaxed to $\ell^1$, which yields easy computation using the shrinkage mapping known as soft thresholding, and can be shown to recover the original solution under certain hypotheses. Recent work has derived a general class of shrinkages and associated nonconvex penalties that better approximate the original $\ell^0$ penalty and empirically can recover the original solution from fewer measurements. We specifically examine p-shrinkage and firm thresholding. In this work, we prove that given data and a measurement matrix from a broad class of matrices, one can choose parameters for these classes of shrinkages to guarantee exact recovery of the sparsest solution. We further prove convergence of the algorithm iterative p-shrinkage (IPS) for solving one such relaxed problem.

description: Based on mean field calculations with Skyrme interactions, we extract a constraint on the isovector effective mass in nuclear matter at saturation density $ρ_0$, i.e., $m_{v}^{\ast}(ρ_0)=(0.77\pm0.03) m$ by combining the experimental data of the centroid energy of the isovector giant dipole resonance (IVGDR) and the electric dipole polarizability $α_{\mathrm{D}}$ in $^{208}$Pb. Meanwhile, the isoscalar effective mass at $ρ_0$ is determined to be $m_{s}^{\ast}(ρ_0)=(0.91\pm0.05) m$ by analyzing the measured excitation energy of the isoscalar giant quadrupole resonance (ISGQR) in $^{208}$Pb. From the constrained $m_{s}^{\ast}(ρ_0)$ and $m_{v}^{\ast}(ρ_0)$, we obtain the isospin splitting of nucleon effective mass in asymmetric nuclear matter of isospin asymmetry $δ$ at $ρ_0$ as $[m_n^{\ast}(ρ_0,δ)-m_p^{\ast}(ρ_0,δ)]/m = Δm^*_1(ρ_0) δ+ O(δ^3)$ with the linear isospin splitting coefficient $Δm^*_1(ρ_0) = 0.33\pm0.16$. We notice that using the recently corrected data on the $α_{\mathrm{D}}$ in $^{208}$Pb with the contribution of the quasideuteron effect subtracted slightly enhances the isovector effective mass to $m_{v}^{\ast}(ρ_0)=(0.80\pm0.03) m$ and reduces the linear isospin splitting coefficient to $Δm^*_1(ρ_0) = 0.27\pm0.15$. Furthermore, the constraints on $m_{v}^{\ast}(ρ)$, $m_{s}^{\ast}(ρ)$ and $Δm^*_1(ρ)$ at other densities are obtained from the similar analyses and we find that the $Δm^*_1(ρ)$ increases with the density.

Identification of patient specific characteristics available upon hospital admission associated with nasal colonization of methicillin-resistant Staphylococcus aureus
Creators: name: Marylou Nicolazzo
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Polymerase chain reaction (PCR) nasal swabs are used for methicillin resistant Staphylococcus aureus (MRSA) colonization screening. Previous institutional data demonstrated that screening protocols based on admission unit resulted in a high yield of negative results and higher costs. The objective of this study was to determine risk factors associated with MRSA colonization for an improvement in targeted screening. This is a retrospective study of potential risk factors included for analysis based on availability within the medical record. Patients were included if admitted between 2016 and 2018 with a MRSA PCR screen obtained within 48 hours. Multivariate logistic regression was used to identify characteristics associated with MRSA colonization. Preliminary results using logistic regression (c-statistic = 0.81) included 9,269 MRSA negative and 2,427 MRSA positive encounters. Admission from a skilled facility (odds-ratio: 2.74), acute (6.92) or history of MRSA infection (2.63), homelessness (1.81), skin and subcutaneous tissue infection (1.71), chronic obstructive pulmonary disease (1.36), venous thromboembolism (1.41), and skin ulcer (1.44), were positively associated with MRSA colonization. The number of hospitalizations in the past 90 days and the number of hospitalizations in the past 91 to 365 days were not adequately generated in the MRSA negative group for analysis. Due to errors in data collection the results of this study are invalid. Further research is needed to determine the true effect of recent hospitalization on MRSA colonization and the cost effectiveness of adopting a risk-based predictive screening model.
Search for resonant t t-bar production in proton-proton collisions at sqrt(s) = 8 TeV

Year: 2015
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search is performed for the production of heavy resonances decaying into top-antitop quark pairs in proton-proton collisions at sqrt(s) = 8 TeV. Data used for the analyses were collected with the CMS detector and correspond to an integrated luminosity of 19.7 inverse femtobarns. The search is performed using events with three different final states, defined by the number of leptons (electrons and muons) from the t t-bar to W b W b decay. The analyses are optimized for reconstruction of top quarks with high Lorentz boosts, where jet substructure techniques are used to enhance the sensitivity. Results are presented for all channels and a combination is performed. No significant excess of events relative to the expected yield from standard model processes is observed. Upper limits on the production cross section of heavy resonances decaying to t t-bar are calculated. A narrow leptophobic topcolor Z' resonance with a mass below 2.4 TeV is excluded at 95% confidence level. Limits are also derived for a broad Z' resonance with a 10% width relative to the resonance mass, and a Kaluza-Klein excitation of the gluon in the Randall-Sundrum model. These are the most stringent limits to date on heavy resonances decaying into top-antitop quark pairs.

Evaluating the Killing Dynamics of Polymyxin B and Meropenem as Monotherapy and Combination Therapy Against Hypermutable Pseudomonas aeruginosa
Creators: name: Agegnehu, Bemnat
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Conserving the activity of the remaining viable last line antibiotic agents for the treatment of highly resistant Pseudomonas aeruginosa (PSA) is a critical challenge and data regarding treatment that is effective against hypermutant PSA is limited. To help overcome this challenge, the objective of this study is to perform phenotypic characterization of 33 PSA clinical isolates from cystic fibrosis (CF) patients, and evaluate the killing dynamics of monotherapy and combination therapy against hypermutable PSA. Phenotypic characterization was performed to detect hypermutators and bacterial susceptibilities for colistin (COL), polymyxin B (PMB), and meropenem (MEM) were evaluated. Static time–kill experiments were performed to determine the rate and extent of bacterial killing using PMB and MEM as monotherapy and combination therapy against hypermutatant and non-hypermutatant strains, PSA
203 and PSA 205, respectively. 6 out of the 33 (18%) PSA clinical isolates obtained from CF patients were determined to be hypermutators. Time-kill results demonstrated poor sustained killing of PMB monotherapy for both isolates. MEM 10 mg/L and MEM 40 mg/L concentrations in combination with PMB 0.5 mg/L and 1 mg/L resulted in regrowth at 8 h for both PSA 203 and PSA 205 isolates, while combination of PMB 2 mg/L and 4 mg/L resulted in sustained bactericidal killing. PMB based combination therapy resulted in superior pharmacodynamic activity compared to monotherapy with either drug, which is consistent with previous in vitro studies that have evaluated polymyxins in combination with carbapenems against highly resistant Gram-negative bacteria in non-CF patients.

description: Focus alternatives are words/phrases that can substitute for the focused constituent of an utterance. In “Carsten has picked [CHERRIES]F from the tree.”, (marked by pitch focus on cherries), the speaker wants to not only convey the fact that Carsten has picked cherries, but also to contrast cherries with other fruit that could have been picked, such as plums. Although focus alternatives are key to understanding the implicit aspects of an utterance, nothing is known about their neural representation. We directly contrasted neural representations of lexico-semantic similarity and focus alternative status using fMRI. Semantic relatedness was reflected in decreased activation in the bilateral superior temporal gyri. By contrast, processing of focus alternatives induced increased activations in the precuneus and the fronto-median wall, two regions previously implicated in discourse processing. These results suggest that focus alternative status is processed separately from semantic relatedness, at the level of discourse integration.

description: The BRITE (BRIght Target Explorer) constellation of nano-satellites performs seismology of bright stars via high precision photometry. In this context, we initiated a high resolution, high signal-to-noise, high sensitivity, spectropolarimetric survey of all stars brighter than V=4. The goal of this survey is to detect new bright magnetic stars and provide prime targets for both detailed magnetic studies and asteroseismology with BRITE. Circularly polarised spectra were acquired with Narval at TBL (France) and HarpsPol at ESO in La Silla (Chile). We discovered two new magnetic B stars: the B3V star i Car and the B8V component of the binary star Atlas. Each star was observed twice to confirm the magnetic detections and check for variability. These bright magnetic B stars are prime targets for asteroseismology and for flux-demanding techniques, such as interferometry.

The purpose of this study was to evaluate the time to first ADR for OPAT patients treated with beta-lactam (BL) therapies for diabetic foot infections (DFI) and osteomyelitis (OM).
Methods: This was a retrospective cohort study of patients enrolled in the UNC OPAT program between 1/2015 and 9/2018 for treatment of DFI or OM. Included patients received one of the following BL: cefepime, ceftriaxone, ertapenem, meropenem, and piperacillin/tazobactam. The primary outcome was time to first ADR during OPAT. Secondary outcomes were estimation of risk of ADR during OPAT for each medication, and ADR types and frequencies observed among patients treated with BL alone or with concomitant vancomycin or daptomycin.
Results: In this cohort, 178 OPAT patients received 193 OPAT courses, for a median duration of 42 days (IQR 38-50). The average patient age was 55 years, and 68% were male.  Kaplan-Meier estimated risk of at least one ADR in the first 8 weeks of therapy was 38.7% (95% CI 29.1% to 48.2%). Ertapenem was the most commonly prescribed BL (76 courses, 39%), followed by ceftriaxone (29, 15%), cefepime (41, 21%), piperacillin/tazobactam (30, 16%), and meropenem (17, 9%). Approximately 40% (76) patients received concomitant vancomycin. ADR was documented in 48 patients (27%) and 56 courses of therapy (29%). ADR resulted in 32 therapy changes and 8 readmissions.
Conclusions: More than one third of patients treated with BL for treatment of DFI and/or OM are at risk of ADR within 8 weeks. ADR commonly resulted in treatment changes, and possible hospital readmission. BL therapy is associated with significant ADR risk, and careful selection and monitoring is essential for optimal patient safety during OPAT.

In der alltäglichen Praxis der bundesdeutschen und europäischen Flüchtlingspolitik findet dies jedoch keine Berücksichtigung. Dies zu ändern, ist ein zentrales Anliegen von Flüchtlingsfrauen, die sich seit einiger Zeit politisch selbst organisieren: »women in exile« protestiert öffentlich gegen die prekären Lebensbedingungen und geht auf die Straße.

description: Introduction: The development of febrile neutropenia in patients receiving myelosuppressive chemotherapies can lead to complications such as infection, hospitalization, and interference in continuation of chemotherapy treatments. Pegfilgrastim (Neulasta®) is often utilized to decrease the risk of febrile neutropenia; however, pegfilgrastim-induced bone pain (PIBP) is a common, and potentially serious, side effect. High rates of PIBP suggest that novel prophylactic treatment strategies would be of significant clinical benefit, such as with gabapentinoids (e.g. gabapentin, pregabalin). The objective of this study is to evaluate the prior use of gabapentinoids in patients with lymphoma and to determine if their use demonstrates an effect on incidence of PIBP.

Methods: A retrospective chart review was conducted of patients who were treated for diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma and received pegfilgrastim (Neulasta®) at the University of North Carolina Medical Center between January 1st and December 31st, 2017. Patients were evaluated for incidence of PIBP and use of gabapentinoids (gabapentin or pregabalin) during chemotherapy treatment.

Results: A total of 135 patients were identified in the final analysis. The incidence of PIBP was 11.1% (N=15) within our DLBCL and follicular population combined, of whom 18.5% (N=25) were on a gabapentinoid therapy during the time they received chemotherapy and pegfilgrastim treatment (P=0.0456). All patients who received gabapentinoid therapies did not report bone pain.

Conclusions: Gabapentinoid use was significantly associated with a decrease in PIBP. Patients who reported PIBP did not receive prior gabapentinoids, supporting that gabapentinoid prophylaxis could reasonably be implemented. However, further study is warranted in a larger population experiencing PIBP to determine if gabapentinoids are associated with decreased PIBP and prospective prophylactic interventions are efficacious.

description: We consider deformations of unbounded operators by using the novel construction tool of warped convolutions. By using the Kato-Rellich theorem we show that unbounded self-adjoint deformed operators are self-adjoint if they satisfy a certain condition. This condition proves itself to be necessary for the oscillatory integral to be well-defined. Moreover, different proofs are given for self-adjointness of deformed unbounded operators in the context of quantum mechanics and quantum field theory.

description: The COVID-19 pandemic has undoubtedly impacted everyone around the globe. In 2020, many countries entered into a lockdown, transforming daily lifestyles into isolation. The SARS-CoV-2 virus that causes the disease COVID-19 slowly spread to different regions of the world, and the first cases of COVID-19 infection in Los Angeles County, California, were documented in mid-January 2020. In March 2020, Governor Gavin Newsom of California declared a state of emergency and implemented a stay-at-home order (1). Therefore, people were quarantined at home, and many “non- essential” businesses were closed, including schools. With no cure available and hospitals reaching maximum capacity, scientists raced to develop vaccines to immunize individuals against the virus. Meanwhile, wastewater technicians began collecting wastewater samples to monitor the presence of the SARS-CoV-2 virus shed from infected residents. We hypothesized that the presence of SARS-CoV-2 RNA in LA County wastewater would decrease as localized vaccination rates increased. Here, we describe a meta-analysis comparing two data sets; the vaccination progression data in Los Angeles County, and the wastewater surveillance PCR
A Systematic Review of the Role of Pharmacists in Vaccination Services in Lowand Middle-Income Countries
Creators: name: McMillan, Stephen

description: Background: Pharmacists’ role in vaccination has expanded in some countries with pharmacists having greater authority to perform various immunization activities, from vaccine storage, vaccine adverse event reporting, vaccination education and advocacy, to vaccine administration. However, pharmacists’ present involvement in vaccination services is poorly understood across low- and middle-income countries (LMICs).

Objective: To identify and synthesize evidence on pharmacists’ roles in vaccination in LMICs.

Methods: We searched three databases (PubMed, Embase, Scopus) and the gray literature to identify articles which described pharmacist involvement in vaccination services in LMICs. We abstracted data on reported roles of pharmacists in vaccination, as well as relevant country,
vaccines, and populations served.

Results: From the initial 612 records we identified, twenty-five (n=25) studies representing 22 LMICs met our inclusion criteria. The most commonly reported role of pharmacists in vaccination across identified LMICs was vaccine advocacy and education (n=15 countries). Pharmacist administered vaccination and storage of vaccines at pharmacies was reported in 8 countries. An additional 6 countries reported allowing vaccination at community pharmacies
by other healthcare professionals. Immunization related training for pharmacists was reported or required in 8 countries. Fewer studies reported that pharmacists have access to patient immunization records in their respective LMICs (n=6 countries) or had reported pharmacist
involvement in vaccine adverse event reporting (n=4 countries).

Conclusions: Pharmacists have the potential to play an important role in increasing access to vaccines and improving coverage, yet evidence of their role in immunization remains limited across LMICs. Greater documentation of pharmacists’ involvement in vaccination services in
LMICs is needed to demonstrate the value of successful integration of pharmacists in immunization programs.

description: The nuclear industry in the United States of America has accumulated about 70,000 metric tons of high-level nuclear waste over the past decades; at present, this waste is temporarily stored close to the nuclear power plants. The industry and the Department of Energy are now facing two related challenges: (i) will a permanent geological repository, e.g., Yucca Mountain, become available in the future, and if yes, when?; (ii) should the high-level waste be transported to interim storage facilities in the meantime, which may be safer and more cost economic? This paper presents a mathematical transportation model that evaluates the economic challenges and costs associated with different scenarios regarding the opening of a long-term geological repository. The model results suggest that any further delay in opening a long-term storage increases cost and consolidated interim storage facilities should be built now. We show that Yucca Mountain’s capacity is insufficient and additional storage is necessary. A sensitivity analysis for the reprocessing of high-level waste finds this uneconomic in all cases. This paper thus emphasizes the urgency of dealing with the high-level nuclear waste and informs the debate between the nuclear industry and policymakers on the basis of objective data and quantitative analysis.
