Year: 2010
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: The propagation of bound optical waves along the surface of a one-dimensional (1-D) photonic crystal (PC) structure is considered. A unified description of the waves in 1-D PCs for both s- and p-polarizations is done via an impedance approach. A general dispersion relation that is valid for optical surface waves with both polarizations is obtained, and conditions are presented for long-range propagation of plasmon-polariton waves in nanofilms (including lossy ones) deposited on the top of the 1-D PC structure. A method is described for designing 1-D PC structures to fulfill the conditions required for the existence of the surface mode with a particular wavevector at a particular wavelength. It is shown that the propagation length of the long-range surface plasmon-polaritons can be maximized by wavelength tuning, which introduces a slight asymmetry in the system.

description: PURPOSE: To report a case of bilateral acute posterior multifocal placoid pigment epitheliopathy (APMPPE) evaluated by optical coherence tomography (OCT), fundus autofluorescence (AF) and microperimetry, both in the acute phase and after resolution of symptoms. METHODS: Complete ophthalmological evaluation, including fluorescein angiography, OCT, AF, and microperimetry upon presentation and 1 month later, after lesions have subsided. An attempt to correlate the findings on presentation and changes after resolution is performed using the results of these new investigational techniques. RESULTS: APMPPE showed hyperreflectance in OCT at the level of the outer retinal layers, without increase in retinal thickness. AF revealed early decreased fluorescence due to a masking effect, and later reveals increased fluorescence after resolution of OCT findings. Function is disturbed at the lesion sites, as shown by microperimetry, and later returns to near normal values on microperimetry. CONCLUSION: APMPPE shows outer retinal layers changes on OCT, which resolve totally after subsidence of the acute phase. AF shows areas of increased fluorescence after resolution, with near normal return of function on microperimetry.
Relevant momentum components of gluons for confinement and chiral symmetry breaking

description: We investigate which momentum components of gluons induce color confinement and spontaneous chiral symmetry breaking in lattice QCD. For this purpose, we formulate a lattice framework to introduce the momentum cutoff of the gluon field. Using this framework, we calculate the quark-antiquark potential, the color flux tube, the chiral condensate, and the Dirac spectrum. Our results suggest that confinement and chiral symmetry breaking are induced by somehow different momentum components of gluons.

Publisher: name: The Science world a Monthly e magazine
Year: 2023

description: Palm oil is one of the basic edible vegetable oils which is used in almost every food processing industry. The palm oil is derived from the oil palm. Globally, about 80% fractions of oil palm are used for edible purposes. Therefore, for a healthy life, the quality of palm oil should be good. The process of palm oil manufacturing is same as other vegetable oil manufacturing. Both palm oil and palm kernel oil are rich sources of saturated fatty acids esterified with glycerol, around 50% and 80%, respectively. To become tolerable for human consumption, palm oil and palm kernel oils should be refined/purified. As other vegetable oils, palm oil refining involves four major steps which are neutralization, degumming, bleaching and deodorization. These four steps were jointly known as the refining process.

description: Cast gold partial crowns (CGPC) are an accepted means of restoring posterior teeth with extended lesions. However, for esthetic reasons, CGPC are being increasingly substituted with partial ceramic crowns (PCC). The aim of the present prospective split-mouth study was to compare the clinical performance of PCC and CGPC. There were 29 patients (male 12, female 17) who participated in the investigation for a total of 58 restorations. In each patient, one CGPC (Degulor C) and one PCC (Vita MarkII/Cerec III) were placed. CGPC were inserted using conventional zinc-phosphate cement (Harvard); PCC were adhesively luted to the cavities (Variolink II/Excite). The restorations were clinically rated using modified United States Public Health Service (USPHS) criteria at baseline and 1 and 2 years after placement. The median patient age was 38 years (range 25-54). There were 29 of the CGPC and 14 PCC placed in molars, while 15 PCC were placed in premolars. All patients were available for the 1- and the 2-year recall. One PCC (1.7%) failed and had to be replaced after 2 years in situ. The rest of the restorations were functional without need of replacement. The evaluation using USPHS criteria revealed no statistically significant differences between CGPC and PCC with the exception of anatomic form: PCC showed occlusal chipping in two cases without need of replacement. From these data, it can be concluded that PCC may provide an esthetic and tissue-conservative alternative to CGPC. However, long-term studies comparing the clinical performance and longevity of cast gold and ceramic partial crowns for posterior teeth are desirable.
Can layered-structure effects be observed, if the Fermi surface is closed?

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: By analyzing the longitudinal conductivity in a quantizing magnetic field directed perpendicularly to the crystal lattice layers, it has been demonstrated that the layered-structure effects can be observed not only in crystals with highly open Fermi surfaces, as was conventionally believed earlier, but also in crystals with closed ones. The calculations were carried out in the constant-relaxation-time approximation. In weak magnetic fields, layered-structure effects manifest themselves as a phase retardation of Shubnikov--de Haas oscillations and a certain increase of the relative contribution made by the latter. In the range of high magnetic fields, there exists an optimal interval, in which the layered-structure effects reveal themselves in the form of a sharp non-monotonous dependence of conductivity on the magnetic field. In addition, it has been shown that the layered-structure effects result in a decrease of the proportionality factor between the magnetoresistance and the magnetic induction in the longitudinal Kapitsa effect. The longitudinal conductivity of layered crystals in ultra-quantum magnetic fields has also been analyzed. It is shown that the following dependences of the magnetoresistance on the magnetic field can be obtained, depending on the model used for the filling of the single Landau subband and on whether the longitudinal conductivity is considered to be of either the drift or diffusion type: $ρ_{zz}\propto TB^{2}$,\ $ρ_{zz}\propto B^{3}$, and $ρ_{zz}\propto B^{4}$.

description: BACKGROUND AND PURPOSE: For accurate positioning of the prostate in external radiotherapy, transabdominal ultrasound localization and positioning systems are available. Reports have stated that probe pressure applied during image acquisition causes clinically relevant prostate displacement. The aim of this study was to investigate the prostate displacement due to the pressure applied during transabdominal ultrasound image acquisition with the BAT ultrasound system. MATERIAL AND METHODS: For ten patients who had undergone iodine-125 seed implantation for brachytherapy of prostate cancer, X-ray simulations were performed before and during ultrasound image acquisition. The iodine seeds are visible on the X-ray images, representing the position of the prostate. The simulator's crosshair, indicating the isocenter, was used as reference coordinate system. For each patient the change in prostate position was calculated based on the seed positions during and after ultrasound examination. RESULTS: A maximum displacement of the prostate of 2.3 mm in anteroposterior and 1.9 mm in craniocaudal direction and a rotational change of up to 2.5 degrees were observed. If the system was not handled correctly and too much pressure was applied, a shift of the prostate of up to 10 mm could be induced. CONCLUSION: Compared to the prostate displacement due to changes in rectal filling, which according to Crook et al. can be as much as 1.7 cm, the maximum displacement of less than 0.3 cm caused by the probe pressure is negligible. However, proper education of the staff and preparation of the patient are essential for the safe use of the system.
A Coupled Map Lattice Model for Rheological Chaos in Sheared Nematic Liquid Crystals

description: A variety of complex fluids under shear exhibit complex spatio-temporal behaviour, including what is now termed rheological chaos, at moderate values of the shear rate. Such chaos associated with rheological response occurs in regimes where the Reynolds number is very small. It must thus arise as a consequence of the coupling of the flow to internal structural variables describing the local state of the fluid. We propose a coupled map lattice (CML) model for such complex spatio-temporal behaviour in a passively sheared nematic liquid crystal, using local maps constructed so as to accurately describe the spatially homogeneous case. Such local maps are coupled diffusively to nearest and next nearest neighbours to mimic the effects of spatial gradients in the underlying equations of motion. We investigate the dynamical steady states obtained as parameters in the map and the strength of the spatial coupling are varied, studying local temporal properties at a single site as well as spatio-temporal features of the extended system. Our methods reproduce the full range of spatio-temporal behaviour seen in earlier one-dimensional studies based on partial differential equations. We report results for both the one and two-dimensional cases, showing that spatial coupling favours uniform or periodically time-varying states, as intuitively expected. We demonstrate and characterize regimes of spatio-temporal intermittency out of which chaos develops. Our work suggests that such simplified lattice representations of the spatio-temporal dynamics of complex fluids under shear may provide useful insights as well as fast and numerically tractable alternatives to continuum representations.

description: AIM: Longitudinal course and genotype-phenotype correlation in patients and carriers with heterozygous mutations in hBEST1 (bestrophin). METHODS: Thirteen patients and seven possible carriers were characterised by mutation analysis with SSCPA and direct sequencing, clinical examination and fundus autofluorescence (AF). Electrophysiology (EOG and mfERG) and optical coherence tomography (OCT) were additionally performed whenever possible. RESULTS: We identified seven different heterozygous mutations in ten unrelated families with Best disease. I296del was the most frequent mutation. Five of nine individuals with I295del and two of three with N99K were asymptomatic carriers. One patient with I295del mutation had funduscopically unilateral Best disease. In three children (all with I295del), EOG initially showed a clearly present light peak that deteriorated during 5 years of follow-up in two of them. Increased AF corresponded well to funduscopically visible lesions. During 3-6 years of follow-up, the lesion area did not change significantly, but there were obvious changes in the inner structure of the lesion. CONCLUSION: In the present series I295del, the most frequent mutation in our study, and N99K showed reduced penetrance. EOG was normal in young patients even if prime signs were visible. The lesion area did not depend on the mutation and did not correlate with VA. Lower VA was associated with a more irregular AF pattern due to scarring or haemorrhage. Our results indicate a disease causing effect that is cumulative over time.

At the intersection of risk : understanding youth who experience both homelessness and parental mental illness
Creators: name: Raithby, Tess
Publisher: name: University of British Columbia
Year: 2018

description: Youth of parents experiencing mental illness are overrepresented amongst homeless and street-involved youth. Understanding the relationship between parental mental illness and youth wellbeing within this population is vital to providing support. This study had two objectives. The first was to describe the lives of youth experiencing this crossover of homelessness and parental mental illness. The second was to determine the relationship between the number of parents experiencing mental illness that a youth has and their wellbeing. Youth with parents experiencing mental illness were at higher risk for relational, environmental, physical and mental health challenges than their street-involved peers who did not have parents with mental illness. Youth who reported both parents as having mental illness experienced the greatest difficulty, followed by youth with one parent with mental illness, then by youth with neither parent with mental illness, suggesting that the challenge experienced was incremental to the number of parents with mental illness. The only area of wellbeing where youth of parents with mental illness did not differ from their peers without parents with mental illness was in their school attendance and aspirations, as well as their thoughts on where they would be in the future, which were largely hopeful. As this population becomes known to front line workers, policy influencers, and policy makers, there is a need for further support that fits with their unique needs. The resources that the youth identified as needed in communities across British Columbia were safe and affordable housing, job training, food, mental health supports, and more. Acknowledging this population of youth experiencing the intersection of both homelessness and parental mental illness means bringing to light their prevalence as well as addressing their difficulties with appropriate and wanted services.
Robust diagnosis of acute bacterial and viral infections via host gene-expression-rank based ensemble machine learning algorithm: a multicohort model development and validation study
Creators: name: Shen, Yifei
Publisher: name: Zenodo
Year: 2024

description: Background

The accurate and prompt diagnosis of infections is essential for improving patient outcomes and preventing bacterial drug resistance. Host gene expression profiling as an approach to infection diagnosis holds great potential in assisting early and accurate diagnosis of infection.

Methods

To improve the precision of infection diagnosis, we developed InfectDiagno, a rank-based ensemble machine learning algorithm for infection diagnosis via host gene expression patterns. Eleven datasets were used as training datasets for the method development and the InfectDiagno algorithm was optimized by the multicohort training samples. Ten datasets were used as independent validation datasets for the method. We further validated the diagnostic capacity of InfectDiagno in a prospective clinical cohort.

Results

After selecting 100 feature genes based on their gene expression ranks for infection prediction, we trained a classifier using both a Noninfected-vs-Infected area under the receiver-operating characteristic curve (Area under the curve (AUC) 0.95 (95% CI 0.93–0.97)) and a Bacterial-vs-Viral AUC 0.95 (95% CI 0.93–0.97).  We then used the Noninfected/Infected classifier together with the Bacterial/Viral classifier to build a discriminating infection diagnosis model. The sensitivity was 0.931 and 0.872, and specificity 0.963 and 0.929, for bacterial and viral infections, respectively. We then applied InfectDiagno to a prospective clinical cohort (N = 517), and found it to classify 95% of the samples correctly.

Conclusions

Our study shows that the InfectDiagno algorithm is a powerful and robust tool to accurately identify infection in a real-world patient population, which has the potential to profoundly improve clinical care in the field of infection diagnosis.

description: Omega Centauri is no longer the only globular cluster known to contain multiple stellar populations, yet it remains the most puzzling. Due to the extreme way in which the multiple stellar population phenomenon manifests in this cluster, it has been suggested that it may be the remnant of a larger stellar system. In this work, we present a spectroscopic investigation of the stellar populations hosted in the globular cluster Omega Centauri to shed light on its, still puzzling, chemical enrichment history. With this aim we used FLAMES+GIRAFFE@VLT to observe 300 stars distributed along the multimodal red giant branch of this cluster, sampling with good statistics the stellar populations of different metallicities. We determined chemical abundances for Fe, Na, O, and n-capture elements Ba and La. We confirm that Omega Centauri exhibits large star-to-star variations in iron with [Fe/H] ranging from ~ -2.0 to ~ -0.7 dex. Barium and lanthanum abundances of metal poor stars are correlated with iron, up to [Fe/H] -1.5, while they are almost constant (or at least have only a moderate increase) in the more metal rich populations. There is an extended Na-O anticorrelation for stars with [Fe/H]

description: Primary cells in culture have a limited capacity to divide and soon reach a non-proliferative state. This cellular senescence limits the investigation of cells derived from human pulp concerning cellular pathways, gene regulation, mechanisms of dentin formation, or responses to material exposure. To overcome this problem, primary human pulp-derived cells were established and transfected with a plasmid containing coding sequences of Simian Virus 40 (SV40) large T-antigen. This resulted in the establishment of several cell clones showing an extension of life span. Expression of T-antigen transcripts and protein was verified by reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry. Primary human pulp cells were cultured until senescence (i.e. up to passage 7) and transfected cells could be cultured to passage 18 after transfection, when a cellular crisis with massive cell death occurred. One clone escaped from crisis and has been maintained in culture for 55 wk. Experiments were performed to characterize transfected cells in comparison to primary cells. Cell morphology and proliferation were analyzed, and expression of cell-specific gene transcripts and proteins (including collagen types I and III, alkaline phosphatase, bone sialoprotein, osteocalcin, and dentin sialophosphoprotein and dentin matrix protein I) was detected by RT-PCR and immunohistochemistry. Transfection of human pulp-derived cells resulted in an immortalized cell line retaining many of the phenotypic characteristics observed in primary cells.

description: NKT cells are activated by CD1d and show an immune regulating function. Here, we investigated whether DX5+ NKT cells could be used to reduce colitis in a chronic colitis mouse model and studied the potential immunological mechanisms involved. Chronic colitis was induced either by transfer of enriched CD62L+ CD4+ T cells to severe-combined-immunodeficient mice or by feeding dextran sodium sulfate to immune competent mice. DX5+ NKT cells were transferred to mice with chronic colitis. Co-transfer of DX5+ NKT cells, but not CD8+ control cells, prevented the onset of colitis, and the immune regulatory effect of DX5+ NKT cells was completely abrogated by injecting CD1d blocking antibody. Moreover, DX5+ NKT cells reduced established colitis in both chronic colitis models. In vitro, DX5+ NKT cells induced cell death of colon-infiltrating lymphocytes isolated from diseased mice. This effect was inhibited in the presence of either anti-CD1d or anti-programmed death ligand-1 (PD-L1) blocking antibodies. The specific potency of DX5+ NKT cells in regulating chronic colitis in two mouse models is demonstrated. In vitro testing suggests that DX5+ NKT cells activated by CD1d induce cell death of colitis-inducing lymphocytes, which is mediated through PD-L1. Therefore, DX5+ NKT cells could be important in the regulation of immune responses associated with chronic colitis.

These quantities are essential, already at the level of generating gauge configurations, being obvious candidates to tune the strange and charm quark masses to their physical values. In particular, we address the problems related to the twisted mass flavor and parity symmetry breaking, which arise when considering a non-degenerate (c,s) doublet. We propose and verify the consistency of three methods to extract the K and D meson masses in this framework.

description: BACKGROUND: Andermann syndrome (OMIM 218000) is an autosomal recessive motor-sensory neuropathy associated with developmental and neurodegenerative defects. The cerebral MRI reveals a variable degree of agenesis of the corpus callosum. Recently, truncating mutations of the KCC3 gene (also known as SLC12A6) have been associated with Andermann syndrome. METHODS: The authors assessed clinically and genetically three isolated cases from Germany and Turkey with symptoms consistent with Andermann syndrome. RESULTS: The authors detected four novel mutations within the KCC3 gene in their patients: two different truncating mutations in the first patient, a homozygous truncating mutation in the second, and a homozygous missense mutation in the third patient. In contrast to the classic phenotype of the Andermann syndrome linked to truncating KCC3 mutations the phenotype and the course of the disease linked to the missense mutation appeared to be different (i.e., showing additional features like diffuse and widespread white matter abnormalities). CONCLUSIONS: Not only truncating but also missense mutations of the KCC3 gene are associated with Andermann syndrome. Different types of KCC3 mutations may determine different clinical phenotypes.
Low-mass visual companions to nearby G-dwarfs

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Complete census of wide visual companions to nearby G-dwarf stars can be achieved by selecting candidates from the 2MASS Point-Source Catalog and checking their status by second-epoch imaging. Such data are obtained for 124 candidates with separations up to 20", 47 of which are shown to be new physical low-mass stellar companions. A list of visual binaries with G-dwarf primaries is produced by combining newly found companions with historical data. Maximum likelihood analysis leads to the companion frequency of 0.13+-0.015 per decade of separation. The mass ratio is distributed almost uniformly, with a power-law index between -0.4 and 0. The remaining uncertainty in the index is related to modeling of the companion detection threshold in 2MASS. These findings are confirmed by alternative analysis of wider companions in 2MASS, removing the contamination by background stars statistically. Extension of this work will lead to a complete detection of visual companions - a necessary step towards reaching unbiased multiplicity statistics over the full range of orbital periods and, eventually, understanding the origin of multiple systems.

Beginning as an undergraduate student during the 1960s, when he covered Hesburgh and Notre Dame for the Associated Press, to 2014 when he conducted his last visit with the frail ninety-seven-year-old priest, Schmuhl maintained a unique relationship with Father Hesburgh. Over time, Hesburgh's meetings with Schmuhl evolved into a friendship, which is documented in this personal and warmhearted portrait of the man who was for decades considered the most influential priest in America. Fifty Years with Father Hesburgh: On and Off the Record contains excerpts and commentary from various interviews Schmuhl conducted with Father Hesburgh about his service as Notre Dame's president, including the most difficult years of his presidency during the 1960s, when Notre Dame and other college campuses were in turmoil because of student protests against the Vietnam War and other issues. Knowing and working with four popes and nine U.S. presidents, Father Hesburgh was a moral force in virtually all major social issues of his day, including civil rights, peaceful uses of atomic energy, third-world development, and immigration reform. Schmuhl records Hesburgh's candid reflections on the U.S. presidents with whom he worked and his assessment of the years after he left the university's presidency and maintained an active life of service in retirement. Schmuhl expresses his devotion and respect in the chapters about Hesburgh's twilight decades. He describes how Hesburgh dealt with macular degeneration and blindness in his later years, enlisting students to read the New York Times and other publications to him. During the 1990s and the first years of the twenty-first century, Father Ted was, as he liked to say, 'everybody's grandfather.' His open-door policy extended beyond students to faculty, staff, alumni, and campus visitors, and continued right up until the end of his life. Throughout the book, Schmuhl captures the essence, spirit, and humanity of a great leader.\u000a\u000a\u00A9 University of Notre Dame\\u000a\u000aCopyright for most content is held by The University of Notre Dame.

description: Advances in image and video capturing technologies, coupled with the introduction of innovative Multiview displays, present new opportunities and challenges to content providers and broadcasters. New technologies that allow multiple views to be displayed to the end-user, such as Super Multiview (SMV) and Free Viewpoint Navigation (FN), aim at creating an immersive experience by offering additional degrees of freedom to the user. Since transmission bitrates are proportional to the number of the cameras used, reducing the number of capturing devices and synthesizing/generating intermediate views at the receiver end is necessary for decreasing the required bandwidth and paving the path toward practical implementation. View synthesis is the common approach for creating new virtual views either for expanding the coverage or closing the gap between existing real camera views, depending on the type of Free Viewpoint TV application, i.e., SMV or 2D walk-around-scene-like (FN) immersive experience. In these implementations, it is common for the majority of the cameras to have dissimilar characteristics and different viewpoints often yielding significant luminance and chrominance discrepancies among the captured views. As a result, synthesized views may have visual artifacts, caused by incorrect estimation of missing texture in occluded areas and possible brightness and color differences between the original real views. In this thesis, we propose unique view synthesis methods that address the inefficiencies of conventional view synthesis approaches by eliminating background leakage and using edge-aware background warping and inter-pixel color interpolation techniques to avoid deformation of foreground objects. Improved occlusion filling is achieved by using information from a temporally constructed background. We also propose a new view synthesis method specifically designed for FN applications, addressing the challenge of brightness and color transition between consecutive virtual views. Subjective and objective evaluations showed that our methods significantly improve the overall objective and subjective quality of the synthesized videos.

description: OBJECTIVE: During the last 2 decades, right/left hemisphere dominance was supposed to affect the immune system differently. Experimental and clinical observations indicate that the left hemisphere plays a crucial role in the development of the immune system. The true relationship between immune response and acute ischemic stroke laterality remains to be elucidated. METHODS: We studied acute right-handed stroke patients admitted to a single acute neurology department with a specialized stroke unit. Being part of our clinical protocol, blood samples were taken within the first 24 h after the onset of stroke symptoms. The medical record of each patient was reviewed, and demographic, clinical laboratory (key criteria: C-reactive protein, CRP, and white blood cell count, WBC) and neuroimaging information was retrieved. All data were presented descriptively, and bivariate test statistics, ANOVA (log-transformed data) or linear correlations were calculated. RESULTS: Fifty-six of the 187 patients admitted to our Stroke Unit between October 2003 and March 2004 with different stroke subtypes according to the TOAST criteria were retrospectively evaluated in order to characterize the impact of stroke laterality on immunoregulatory response measured by CRP levels and WBC. Correlation analysis revealed that left-sided ischemic stroke yielded a significantly higher correlation between CRP levels and WBC. Following left-sided stroke, a more marked variability in CRP and WBC was found compared to patients with right-sided ischemic stroke, although ANOVA did not show significant differences between immune response values as a function of stroke subtypes. CONCLUSIONS: We identified an association between stroke laterality and immunoregulatory response in patients with acute ischemic stroke. Left-sided stroke may be considered as a direct risk factor for infectious disease or immune deficits and should attract special attention. However, these preliminary results need be confirmed by controlled studies.

description: P2P computing lifts taxing issues in various areas of computer science. The largely used decentralized unstructured P2P systems are ad hoc in nature and present a number of research challenges. In this paper, we provide a comprehensive theoretical survey of various state-of-the-art search and replication schemes in unstructured P2P networks for file-sharing applications. The classifications of search and replication techniques and their advantages and disadvantages are briefly explained. Finally, the various issues on searching and replication for unstructured P2P networks are discussed.

description: Define a random variable $ξ_n$ by choosing a conjugacy class $C$ of the Sylow $p$-subgroup of $S_{p^n}$ by random, and let $ξ_n$ be the logarithm of the order of an element in $C$. We show that $ξ_n$ has bounded variance and mean order $\frac{\log n}{\log p}+O(1)$, which differs significantly from the average order of elements chosen with equal probability.

description: BACKGROUND: Photodynamic therapy (PDT) with 5-aminolaevulinic acid (ALA) is an effective and safe treatment option for the treatment of actinic keratosis (AK). Incoherent lamps are often used, matching the absorption maxima of ALA. OBJECTIVES: A comparative trial was performed to evaluate the efficacy of recently developed light-emitting diodes (LEDs). METHODS: Human epidermal keratinocytes were incubated for 24 h with ALA (100, 200, 300, 400 or 500 micromol L(-1)) and irradiated consecutively using either an incoherent halogen lamp (lambda(em) = 580-750 nm; 24 J cm(-2); 40 mW cm(-2)) or an LED system (lambda(em) = 633 +/- 3 nm; 3, 6, 12 or 24 J cm(-2); 40 mW cm(-2)). Topical ALA-PDT was performed on 40 patients with AK (n = 584) in a symmetrical distribution suitable for two-sided comparison. After incubation with ALA (20% in cream base) irradiation was performed with the incoherent lamp (100 J cm(-2); 160 mW cm(-2)) on one side and the LED system (40 J cm(-2); 80 mW cm(-2)) on the opposite side followed by re-evaluation up to 6 months. RESULTS: No significant differences between the LED system (3, 6, 12 or 24 J cm(-2)) and the incoherent light source (24 J cm(-2)) regarding cytotoxicity was found in vitro. The complete remission rate yielded in the in vivo investigation was also not significantly different at 6 weeks (P = 0.95), 3 months (P = 0.75) and 6 months (P = 0.61) following therapy. Six weeks following therapy complete remission rates of 84.3% (LED system) and 82.8% (incoherent lamp) were achieved. There was also no significant difference between both light sources regarding pain during light treatment (P = 0.67), patient satisfaction (P = 1.0) or cosmesis (P = 1.0) following therapy. CONCLUSIONS: These results show the efficacy of an LED system for ALA-PDT both in vitro and in vivo. ALA-PDT with the LED system showed a noninferiority regarding the clinical outcome in the treatment of AK compared with the incoherent lamp.

description: An initial local excitation in a confined quantum system evolves exploring the whole system, returning to the initial position as a mesoscopic echo at the Heisenberg time. We consider a two weakly coupled spin chains, a spin ladder, where one is a quantum channel while the other represents an environment. We quantify decoherence in the quantum channel through the attenuation of the mesoscopic echoes. We evaluate decoherence rates for different ratios between sources of amplitude fluctuation and dephasing in the inter-chain interaction Hamiltonian. The many-body dynamics is seen as a one-body evolution with a decoherence rate given by the Fermi golden rule.

description: In this paper we investigate the electron-phonon contribution to the resistivity of suspended single layer graphene. In-plane as well as flexural phonons are addressed in different temperature regimes. We focus on the intrinsic electron-phonon coupling due to the interaction of electrons with elastic deformations in the graphene membrane. The competition between screened deformation potential vs fictitious gauge field coupling is discussed, together with the role of tension in the suspended flake. In the absence of tension, flexural phonons dominate the phonon contribution to the resistivity at any temperature $T$ with a $T^{5/2}_{}$ and $T^{2}_{}$ dependence at low and high temperatures, respectively. Sample-specific tension suppresses the contribution due to flexural phonons, yielding a linear temperature dependence due to in-plane modes. We compare our results with recent experiments.
