description: The decays of $D$ mesons to $K l ν$ and $K^* l ν$ final states exhibit significant deviations from the predictions of heavy-quark symmetry, as one might expect since the strange quark's mass is of the same order as the QCD scale. Nonetheless, in order to understand where the most significant effects might lie for heavier systems (such as $B \to D lν$ and $B \to D^* lν$), the pattern of these deviations is analyzed from the standpoint of perturbative QCD and ${\cal O}(1/m_s)$ corrections. Two main effects are noted. First, the perturbative QCD corrections lead to an overall decrease of predicted rates, which can be understood in terms of production of excited kaonic states. Second, ${\cal O}(1/m_s)$ effects tend to cancel the perturbative QCD corrections in the case of $Klν$ decay, while they have minimal effect in $K^*lν$ decay.

Molecular mechanisms underlying staphylococcal induced osteomyelitis.

description: Osteomyelitis is a debilitating infectious disease of the bone. It is mainly caused by Staphylococcus aureus and Staphylococcus epidermidis, being the second one, the major cause of implant-related osteomyelitis. Osteomyelitis is associated with significant morbidity and mortality and it is mainly characterised by weakened bones due to progressive bone loss and in flammation . However, currently the mechanism through which either bone destruction or inflammation occurs in osteomyelitis patients is poorly understood. The data presented in this thesis shows that S. aureus and S. epidermidis bind differently to bone and follow distinct pathways in the initiation and progression of disease. While S. epidermidis interacts with osteoblast via SdrG binding to fibrinogen which in turn binds to an integrin receptor on the osteoblast surface, S. aureus uses a very specific interaction mediated by S. aureus protein A (SpA) and Tum or Necrosis factor receptor 1 (TNFR-1) to bind osteoblast. A study of the interaction between S. epidermidis and osteoblast demonstrated that S.epidermidis SdrG protein is involved in the inhibition of osteoblast growth but not in osteoblast d e a th following infection. On the othe r hand, investigation of the effect following SpA binding to TNFR-1 revealed this to be crucial in the activation o f the receptor pathway mediating multiple signals ultimately leading to suppression of bone growth together with bone destruction and inflammation . Here, it is shown th at upon infection with S. aureus, osteoblasts undergo apoptosis, through caspase 3 cleavage, and the activation of inflammatory processes occurs via NFkB activation associated with IkB degradation and the release of IL6. All of these events were prevented when blocking SpA or TNFR-1 or both, confirming the importance of this interaction in the onset and development of disease. The findings presented in this thesis describe for the first time interactions between Staphylococci and osteoblast and th e ir role in the progression of Staphylococcal induced osteomyelitis. Furthermore, this study may also highly contribute for the development of a novel or improved therapy for osteomyelitis patients using th e TNFR-1.

The appearance of a cosmological constant in the five dimensional Einstein--Hilbert action produces a special dilaton potential in the four dimensional effective string action. Cosmological scenarios implemented by our solutions are discussed.

Here $e>0$ is the perturbation parameter. Our approach, based on the topological degree theory and the averaging theory, permits to weaken the conditions in [K.R.

Health-based maximum contaminant level support document: Perfluorononanoic acid (PFNA)
Creators: name: No Name Supplied
Publisher: name: No Publisher Supplied
Year: 2015

description: A Health-based Maximum Contaminant Level (Health-based MCL) for perfluorononanoic acid (PFNA, C9) was developed to protect for chronic (lifetime) drinking water exposure. The Health- Based MCL is based on a study of developmental effects in which pregnant mice were exposed to PFNA for 16 days. The Health-based MCL is further supported by data on effects in the offspring in the same study, and on increased liver weight and other effects in additional rodent studies from the same and other laboratories. Benchmark dose modeling was performed on PFNA levels in blood serum that caused increased maternal liver weight in the pregnant mice. Appropriate uncertainty factors were applied to protect sensitive human subpopulations, account for differences between human and experimental animals, protect for chronic exposure, and account for the incomplete toxicology database for PFNA. Based on available toxicokinetic data from animal and humans, a ratio of 200:1 was used to estimate the increase in PFNA in human blood serum from ongoing exposure to a given concentration of PFNA in drinking water. A chemical specific Relative Source Contribution factor of 50% was developed based on the most recent NHANES data for the 95th percentile PFNA serum levels in the U.S. general population. Using this information, a Health-based MCL protective for chronic drinking water exposure of 13 ng/L (0.013 μg/L) was derived.

description: We propose to raise the critical temperature $T_c$ for superconductivity in doped C$_{60}$ molecular crystals by increasing the electronic density of states at the Fermi level $N(E_F)$ and thus the electron-phonon coupling constant in low-dimensional C$_{60}$ nanoarrays. We consider both electron and hole doping and present numerical results for $N(E_F)$, which increases with decreasing bandwidth of the partly filled $h_u$ and $t_{1u}$ derived frontier bands with decreasing coordination number of C$_{60}$. Whereas a significant increase of $N(E_F)$ occurs in 2D arrays of doped C$_{60}$ intercalated in-between graphene layers, we propose that the highest $T_c$ values approaching room temperature may occur in bundles of nanotubes filled by 1D arrays of externally doped C$_{60}$ or La@C$_{60}$, or in diluted 3D crystals, where quasi-1D arrangements of C$_{60}$ form percolation paths.

The energy gaps are observed to be increasing with decreasing $T_c$ values. The coherence peaks are asymmetric with the peaks at the filled states being larger than those at the empty ones. The asymmetry increases with decreasing $T_c$. The observed asymmetry and its $T_c$ dependence can be explained by considering the Mott insulating nature of the material at the undoped state.

description: An association between provenance variations in growth performance of the Japanese larch (Larix kaempferi) and climatic conditions in the provenances has been found in the natural distributional range in central Japan. To verify whether this association differs in northern Japan, outside of the original habitats, we examined stem productivity of 30-year-old trees planted in three test sites in the Nagano Prefecture in central Japan and three test sites in the Hokkaido Prefecture in northern Japan. The trees originated from 25 provenances throughout the whole range of the natural distribution. Stem-productivity variances of interactions between the test sites and provenances were relatively small. Provenance correlations in the stem productivity among most of the tests sites were positive. Climatic conditions in the provenances and test sites were summarized as two indices: a gradient of warmth and drought (higher temperature and less precipitation at lower elevations) and a cline of climatic seasonality (from the northwestern to southeastern sides of the Japanese mainland, with decreasing and increasing seasonal variations in temperature and precipitation, respectively). The maximum stem productivity among the provenances was frequently observed at both extremities of the warmth/drought gradient and on the southeastern side of the climate-seasonality cline. These associations were detected in test sites in both central and northern Japan. These findings suggest similar provenance variations in growth performance of the Japanese larch among different growing environments in Japan.

An Epidemiological Investigation of Adolescents and Symptomatic High Risk for Psychosis
Creators: name: Kelleher, Ian
Publisher: name: Royal College of Surgeons in Ireland
Year: 2019
Subjects: Uncategorized

description: Background: Epidemiological research has shown that hallucinations and delusions, the classic symptoms of psychosis, are far more prevalent in the population than actual psychotic disorder. These symptoms are especially prevalent in childhood and adolescence. Longitudinal research has demonstrated that psychotic symptoms in adolescence increase risk for psychotic disorder in adulthood. There has been little research, however, on the immediate clinicopathological significance of psychotic symptoms in adolescence and on the prevalence of prodromal risk syndromes in the community. Aims: Aim 1 : To assess the prevalence of psychotic symptoms and the association of psychotic symptoms with age and with DSM-IV Axis-1 psychopathology Aim 2: To assess the relationship between psychotic symptoms and suicidal behaviour Aim 3: To assess the neurocognitive profile of adolescents who report psychotic symptoms Aim 4: To assess the prevalence of prodromal risk syndromes in the population and assess associations with non-psychotic psychopathology and global functioning Method: Data from three population studies were used: Study 1 involved a school-based survey of 1,131 1 1 -to 13-year olds for psychotic symptoms, assessed using the Adolescent Psychotic Symptom Screener, and for emotional and behavioural symptoms of psychopathology, assessed using the Strengths and Difficulties Questionnaire. Studies 2 and 3 involved in-depth diagnostic interview assessments of psychotic symptoms and lifetime Axis-1 disorders in two community samples of 11-to 15-year olds, involving 423 adolescents in total. Psychotic symptoms, Axis-1 psychiatric disorders and suicidal behaviour were assessed using the Schedule for Affective Disorders and Schizophrenia (K-SADS). Global functioning was assessed using the Children’s Global Assessment Scale. Neurocognition was assessed using the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) consensus battery. Prodromal risk syndromes were assessed using the criteria of prodromal syndromes from the Structured Interview for Prodromal Syndromes. Results: A majority of community-based adolescents who reported psychotic symptoms had at least one lifetime diagnosable Axis-1 disorder on clinical interview: Study 2, Odds ratio (OR)=3.57, 95% confidence interval (CI95)=1.87-6.84, p Conclusions: The majority of adolescents who report psychotic symptoms have at least one lifetime diagnosable Axis-1 disorder and demonstrate poorer neurocognitive performance than controls. Prodromal risk syndromes are relatively common in the community, which has implications for the proposed DSM-V diagnosis of Attenuated Psychosis Syndrome. Psychotic symptoms are important risk markers for severe multiple Axis-1 disorders and suicidal behaviour and should be routinely assessed in child and adolescent psychiatric clinics.

An investigation of event-related potentials in adolescents with psychotic-like experiences
Creators: name: Murphy, Jennifer
Publisher: name: Royal College of Surgeons in Ireland
Year: 2019
Subjects: Uncategorized

description: It is well established that patients with schizophrenia exhibit a wide range of deficits in sensory and cognitive processing. Neurophysiological mechanisms underlying these abnormalities are also impaired in patients with schizophrenia, as well as in first episode and prodromal patients and in unaffected family relatives. Recent evidence has documented the presence of psychotic-like experiences (PLEs) and other risk factors for psychosis in the general population (Kelleher and Cannon, 2011; Van Os et al, 2000). Adolescence is a critical time period that is marked by an increased vulnerability for the development of psychopathology, particularly psychosis (Poulton et al, 2000). Research has documented a relationship between the onset of psychotic symptoms in adolescence and the development of a psychotic disorder in adulthood (Poulton et al, 2000). Therefore, this group can be conceptualised as an at-risk group for psychosis. This thesis examined neural correlates of sensory and cognitive processing in adolescents with PLEs from the general population. Using the event-related potential technique (ERP), we compared adolescents with PLEs to a group of age matched controls on tasks of auditory change detection, response inhibition, receptive language and semantic comprehension. The adolescents with PLEs were characterised by reductions in mismatch negativity (MMN) and P300 amplitude on tasks of auditory discrimination and language comprehension. In comparison to the controls, the adolescents with PLEs displayed delayed latency on the P300 component and prolonged latency on the N400 component on tasks of response inhibition and language comprehension, respectively. The abnormalities observed in these tasks were evident over frontal regions, which suggested possible evidence of early frontal dysfunction in this at-risk group. Evidence of impaired neurophysiological activity in adolescents with PLEs provides important information regarding risk for psychosis a t the level of the general population.

description: The complete relativistic $O(α^2)$ nuclear structure correction to the energy levels of ordinary (electronic) and muonic hydrogen-like atoms is investigated. The elastic part of the nuclear structure correction is derived analytically. The resulting formula is valid for an arbitrary hydrogenic system and is much simpler than analogous expressions previously reported in the literature. The analytical result is verified by high-precision numerical calculations. The inelastic $O(α^2)$ nuclear structure correction is derived for the electronic and muonic deuterium atoms. The correction comes from a three-photon exchange between the nucleus and the bound lepton and has not been considered in the literature so far. We demonstrate that in the case of deuterium, the inelastic three-photon exchange contribution is of a similar size and of the opposite sign to the corresponding elastic part and, moreover, cancels exactly the model dependence of the elastic part. The obtained results affect the determination of nuclear charge radii from the Lamb shift in ordinary and muonic atoms.

Hypothesis-Driven Proteomic Data-Analysis of Plasma from Subjects in the At-Risk Mental State

description: Strong evidence now supports an association between systemic abnormalities and schizophrenia pathology. Furthermore, the clinical outcome in schizophrenia is significantly improved by early identification and treatment. These factors are driving the search for blood-based biomarkers for the disorder. Promising biomarker findings are hampered however by a relative lack of studies in prodromal psychosis, such as the at-risk mental state (ARMS). Poor replication of findings, particularly across highthroughput mass-spectrometry studies, is also problematic. A technique which has begun to emerge prominently in recent years, Data-Independent Analysis (DIA), has the ability to overcome limitations in reproducibility associated with more traditional Data-Dependent Acquisition (DDA) methods due to its more comprehensive sampling nature. Participants were recruited from the UK Avon Longitudinal Study of Parents and Children (ALSPAC) cohort. Here, DIA coupled to cutting-edge bioinformatics is used to 1) identify and 2) validate candidate biomarkers for the transition from ARMS to psychotic disorder (age 11 ARMS subjects who transitioned to psychotic disorder at age 18; n=19 versus those who did not transition; n=17). Biomarker candidates were derived from the top pathway implicated in the literature on drug-free schizophrenia, the acute-phase response, for identification (53 proteins; target list 1) and from the results of DDA conducted on the same samples, for validation (19 proteins; target list 2). Four acute-phase proteins (SERPING1, ITIH3, AGT, and APOA1) were found to be differentially expressed in ARMS subjects who transitioned to psychosis, in comparison to those who did not. Three DDA derived biomarker candidates were similarly validated (F5, APOE and ITIH3). Here the potential of this particular DIA workflow as a high-throughput tool for biomarker identification and validation in schizophrenia is demonstrated. The identification of a small biomarker panel consisting of proteins converging on the acute-phase response and coagulation pathway provides an insight into the development of psychotic disorders and an opportunity for future biomarker studies in prodromal patients to build on the current findings.

description: In this paper we consider a class of nonlinear periodic differential systems perturbed by two nonlinear periodic terms with multiplicative different powers of a small parameter $e>0$. For such a class of systems we provide conditions which guarantee the existence of periodic solutions of given period $T>0$. These conditions are expressed in terms of the behaviour on the boundary of an open bounded set $U$ of $R^n$ of the solutions of suitably defined linearized systems. The approach is based on the classical theory of the topological degree for compact vector fields. An application to the existence of periodic solutions to the van der Pol equation is also presented.

description: Biogenic iron oxides (BioFeO) formed by Leptothrix sp. and Gallionella sp. were compared with chemically formed iron oxides (ChFeO) for their suitability to remove and recover phosphate from solutions. The ChFeO used for comparison included a commercial iron-based adsorbent (GEH) and chemically oxidized iron precipitates from groundwater. Despite contrary observations in earlier studies, the batch experiments showed that BioFeO do not have superior phosphate adsorption capacities compared to ChFeO. However, it seems multiple mechanisms are involved in phosphate removal by BioFeO which make their overall phosphate removal capacity higher than that of ChFeO. The overall phosphate removal capacity of Leptothrix sp. deposits was 26.3 mg P/g d.s., which could be attributed to multiple mechanisms. This included adsorption on the solid phase (6.4 mg P/g d.s.) as well as removal via precipitation and/or adsorption onto suspended complexes released from the BioFeO of Leptothrix sp. (19.6 mg P/g d.s.). Only a very small part of phosphorus (0.3 mg P/g d.s.) was retained in the Leptothrix sp. sheats during bacterial growth. Deposits of Gallionella sp. had an overall phosphate removal capacity of 39.6 mg P/g d.s. Significant amounts of phosphate were apparently incorporated into the Gallionella sp. stalks during their growth (31.0 mg P/g d.s.) and only one-fifth of the total phosphate removal can be related to adsorption (8.6 mg P/g d.s.). Their overall ability to immobilize large quantities of phosphate from solutions indicates that BioFeO could play an important role in environmental and engineered systems for removal of contaminants.

description: Long-term operation of a ground source heat pump (GSHP) in severe cold regions leads to a gradual decrease in subsurface soil temperature, affecting system performance. This paper proposes a solar assisted ground source heat pump (SAGSHP) system consisting of solar photovoltaic thermal (PV/T) and GSHP. Through TRNSYS software, the system was analyzed for 10 years of dynamic simulation in a severe cold region. The results are listed below: (1) The SAGSHP system is capable of effectively lessening the maximal temperature of photovoltaic (PV) modules in Changchun, Shenyang, and Harbin, China, by 21.73%, 13.67%, and 19.10%, respectively. The power generation efficiency of PV modules in these three locations can be maintained at about 22% year-round. (2) After ten years of operation, the coefficients of performance (COP) of the heat pumps have increased by 5.70%, 6.80%, and 5.01%, respectively, relative to the first year, showing good stability. (3) The soil temperatures at all three locations were stabilized during the ten years of operation. This study provides a theoretical basis for devising and installing SAGSHP in severe cold regions.

description: This paper investigates the much-debated Jurassic/Cretaceous (J/K) boundary as well as the Early Cretaceous climate using palynomorphs of the Chichali Formation, Upper Indus Basin, North Pakistan. Based on the palynostratigraphy, two dinoflagellates and one spore/pollen assemblage are recorded, suggesting a Kimmeridgian to Valanginian age for the sediments of the Chichali Formation. The palynostratigraphic results further suggest that the Tithonian to Berriasian strata are truncated along the J/K boundary. The warm and humid conditions are supported by the consistent dominance of ferns corresponding to the Schizaeaceae and the intermittent appearance of herbs from Gleicheniaceae. Such climatic conditions are further supported by the consistent presence of evergreen trees with a broad leave of Cyatheaceae and Matoniaceae. The warm and humid conditions are also supported by conifers of the Araucariaceae in association with Cycadaceae. Such conditions during the Valanginian are further supported by the switch from the Bajocian–Oxfordian shallow carbonates of the Samana Suk Formation to the Kimmeridgian–Valanginain clastics of the Chichali Formation. Hence, the expansion of warm and humid tropical flora to the middle latitude (∼40°S) during the Valanginain hints strongly for global warming instead of previously suggested global cooling.KEY POINTS:Palynostratigraphic investigation shows Kimmeridgian to Valanginian age for the Chichali Formation, Upper Indus Basin, Pakistan.The J/K boundary is marked by an unconformity along which the Tithonian to Berriasian time record is missing.The reconstruction of paleovegatation indicates warm humid climate during the Valanginian instead of previously reported global cooling.

description: The supernova impostor SN 2010da located in the nearby galaxy NGC 300, later identified as a likely supergiant B[e] high-mass X-ray binary, was simultaneously observed by NuSTAR and XMM-Newton between 2016 December 16 and 20, over a total time span of 310 ks. We report the discovery of a strong periodic modulation in the X-ray flux with a pulse period of 31.6 s and a very rapid spin-up, and confirm therefore that the compact object is a neutron star. We find that the spin period is changing from 31.71 s to 31.54 s over that period, with a spin-up rate of -5.56 x 10-7 s s-1, likely the largest ever observed from an accreting neutron star. The spectrum is described by a power-law and a disk black-body model, leading to a 0.3-30 keV unabsorbed luminosity of 4.7 x 10^39 erg s-1. Applying our best-fit model successfully to the spectra of an XMM-Newton observation from 2010, suggests that the lower fluxes of NGC 300 ULX1 reported from observations around that time are caused by a large amount of absorption, while the intrinsic luminosity was similar as seen in 2016. A more constant luminosity level is also consistent with the long-term pulse period evolution approaching an equilibrium value asymptotically. We conclude that the source is another candidate for the new class of ultraluminous X-ray pulsars.

description: We extend the Poisson bracket from a Lie bracket of phase space functions to a Lie bracket of functions on the space of canonical histories and investigate the resulting algebras. Typically, such extensions define corresponding Lie algebras on the space of Lagrangian histories via pull back to a space of partial solutions. These are the same spaces of histories studied with regard to path integration and decoherence. Such spaces of histories are familiar from path integration and some studies of decoherence. For gauge systems, we extend both the canonical and reduced Poisson brackets to the full space of histories. We then comment on the use of such algebras in time reparameterization invariant systems and systems with a Gribov ambiguity, though our main goal is to introduce concepts and techniques for use in a companion paper.

description: Biogenic iron oxides (BioFeO) formed by Leptothrix sp. and Gallionella sp. were compared with chemically formed iron oxides (ChFeO) for their suitability to remove and recover phosphate from solutions. The ChFeO used for comparison included a commercial iron based adsorbent (GEH) and chemically oxidized iron precipitates from groundwater. Despite contrary observations in earlier studies the batch experiments showed that BioFeO do not have superior phosphate adsorption capacities compared to ChFeO. However, it seems multiple mechanisms are involved in phosphate removal by BioFeO which make their overall phosphate removal capacity higher than that of ChFeO. The overall phosphate removal capacity of Leptothrix sp. deposits was 26.3 mg P/g d.s., which could be attributed to multiple mechanisms. This included adsorption on the solid phase (6.4 mg P/g d.s.) as well as removal via precipitation and/or adsorption onto suspended complexes released from the BioFeO of Leptothrix sp. (19.6 mg P/g d.s.). Only a very small part of phosphorus (0.3 mg P/g d.s.) was retained in the Leptothrix sp. sheats during bacterial growth. Deposits of Gallionella sp. had an overall phosphate removal capacity of 39.6 mg P/g d.s. Significant amounts of phosphate were apparently incorporated into the Gallionella sp. stalks during their growth (31.0 mg P/g d.s.) and only one-fifth of the total phosphate removal can be related to adsorption (8.6 mg P/g d.s.). Their overall ability to immobilize large quantities of phosphate from solutions indicate that BioFeO could play an important role in environmental and engineered systems for removal of contaminants.

description: We address the problem of determining finite subsets of Delone sets $\varLambda\subset\R^d$ with long-range order by $X$-rays in prescribed $\varLambda$-directions, i.e., directions parallel to non-zero interpoint vectors of $\varLambda$. Here, an $X$-ray in direction $u$ of a finite set gives the number of points in the set on each line parallel to $u$. For our main result, we introduce the notion of algebraic Delone sets $\varLambda\subset\R^2$ and derive a sufficient condition for the determination of the convex subsets of these sets by $X$-rays in four prescribed $\varLambda$-directions.

description: Although colonoscopy remains the gold standard for determining bowel diseases, it’s invasive and expensive. New non-invasive diagnostic methods are urgently needed as an initial screening modality. We aimed to investigate the value of fecal calprotectin (FC) and fecal immunochemical test (FIT) in differentiation of significant and non- significant bowel diseases. In this prospective study, consecutive individuals were included if they underwent colonoscopy for symptoms of lower gastrointestinal (GI) tract, positive fecal occult blood test, surveillance for IBD or colorectal cancer (CRC) screening. Diagnostic value of FC and FIT in discriminating significant bowel diseases (advanced neoplasia, active inflammatory bowel diseases or bowel inflammation due to other causes) and non-significant bowel diseases (normal, asymptomatic diverticulum, non-adenomatous polyp, or non-advanced neoplasia) were evaluated. Among 201 individuals included, 107 patients had significant bowel diseases. FC and FIT had an area under the curve (AUC) of 0.722 (95% confidence interval [CI] 0.653–0.792) and 0.797 (95%CI 0.734–0.860), respectively, for determining significant bowel diseases. Combination of FC and FIT predicted significant bowel diseases with an AUC, sensitivity, specificity, and accuracy of 0.832 (95% CI 0.775–0.890), 77.6%, 74.5%, and 76.1%, respectively. Moreover, combination of FC and FIT was more sensitive among patients with lower GI symptoms than asymptomatic individuals (80.8% vs. 74.1%) to identify significant bowel diseases. A single measurement of FC or FIT is not sufficiently accurate to identify patients with significant bowel disease. However, combination of FC and FIT can help increase the sensitivity, especially in patients with lower GI symptoms.
Polarization Profiles of Scattered Emission Lines. II. Upstream Dust Scattering in the HH 1 Jet

description: Detailed comparisons are made between observations of scattered light upstream of the head of the HH~1 jet and predictions of simple scattering models. It is shown that, in order to unambiguously determine the velocity of the head of the jet (bow shock) with respect to the upstream dust, existing spectroscopic observations are insufficient and that spectropolarimetric observations of the scattered light are necessary. Such an independent measure of the bow shock velocity is important in order to test ``multiple outflow'' theories of Herbig-Haro jets. It is also shown 2that the scattering dust must have a very forward-throwing scattering phase function ($\langle\cosθ\rangle\msim 0.7$) and slight evidence is found for a dust-gas ratio that is higher than average.
