description: In this paper, we investigated a set of narrow endemics of Centaurea subsect. Phalolepis from the mountains of South Italy (mainly Calabria and Salento), segregated from the widespread species Centaurea deusta, using microsatellite (SSR) markers. The goal was to analyse the genetic makeup (levels and structure) of C. deusta and the segregated species and verify whether genetic clusters were in agreement with current classification of the species. With C. deusta, we also carried out an ecological niche modelling (ENM) analysis to check its potential distribution under present climatic conditions and to project it to the Last Glacial Maximum (LGM). As also found in former studies with subsect. Phalolepis in Greece and Turkey using the same set of SSRs, genetic diversity for the segregated Italian species was higher than expected for narrow endemics with small populations. Genetic clusters, however, were not correlated with the described species and did not support the segregation of the purported narrow endemics from a widely defined C. deusta. The results of the ENM indicate that the Adriatic Sea was a migration corridor for C. deusta at the LGM.

description: In designing flight control system or developing high-level flight simulator, the accurate and comprehensive representation of the aerodynamic characteristics of an aircraft is required. In case of high manoeuvrable unstable aircraft, the identification of the aerodynamic characteristics can be challenging because of the engaged control system. In this paper, it is aimed to estimate aerodynamics characteristics of highly manoeuvrable unstable aircraft with engaged control system for simulation data. For this purpose, F-16 nonlinear aircraft is modelled using aerodynamic database is derived from a low speed wind tunnel test. In analysis of simulated data, equation error and output error methods in time domain are used to estimate aerodynamic parameters defined in model postulate. The goal is to find a compact model structure which has adequate complexity to capture the nonlinearities. Using FAA specified guidelines in terms of tolerances on each variables for short-period and Dutch-roll manoeuvres, the identified model is validated.

description: We present results for the {\em dynamical}\/ magnetic susceptibility of the $t$-$J$ model, calculated with the dynamical mean field theory. For $J=0$ we find enhanced ferromagnetic correlations but an otherwise relatively $\vec{q}$-independent dynamical magnetic susceptibility. For $J>0$ the explicit antiferromagnetic exchange leads to a dynamic spin structure factor with the expected peak at the antiferromagnetic Bragg point.

title: Computational Analysis of the Steric Gate Region in the Y-Family DNA Polymerases
Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2020

description: Background: The Y-family DNA polymerases specialize in translesion synthesis. This is ascribed to steric clashes with a residue near the active site, the steric gate and 2′-OH (hydroxyl) group. The steric gate provides by steric and physical constraints an effective mechanism for most DNA polymerases to selectively insert deoxyribonucleotides. Deoxyribonucleotides synthesis into DNA leads to replication stress and genomic instability. Defective replication leads to mutation in the protein sequences which can prevent the drug from binding to the target and consequently blocking treatment of disease. The aim of this research study was to determine the effectiveness of sequence pattern recognition to provide better insights into the Y-family DNA polymerases structure-function relationships. Methods and Materials: A combination of methods of computational structure analysis, correlated mutations, and sequence pattern recognition were used. Multiple Sequence Alignments (MSA) of the UmuC domain from PFAM were used to identify critical residues in the steric gate position. The Consurf database was used to calculate conservation score and COUSCOus was used to calculate correlated mutations of the conserved regions. Residue pair scores were used as an amino acid pair position comparison analysis in order to assess the predicted residue-residue interactions. Results: 17,662 aligned sequences (as of April 11th, 2020) from PFAM of the UmuC domain were used; of these, 13,768 sequences (78.0%) had phenylalanine (F) or tyrosine (Y) at the steric gate position, 369 sequences (2.1%) had another residue at steric gate position and 3,525 sequences (20.0%) had no known steric gate. 150 (4.3%) of these were found to be fragments and were not considered for the analysis. An example of the structure 5KFZ from the human DNA polymerase eta retrieved from PFAM yielded conservation scores from the consurf database that were plotted against the correlation values from COUSCOus in r. An intersection showed that residues that were highly conserved were similarly correlated. Conclusions: The steric gate of approximately 90% of organisms is as expected with tyrosine (Y) and phenylalanine (F) in this position. However, a small number of organisms have been known to have been a different residue at the position. Understanding how these organisms discriminate against deoxyribonucleotides will give insight on how are they able to function. Specific human DNA repair and lesion bypass polymerases have been proposed to be anticancer drug targets. For instance, Pol η (eta) appears to be specialized in bypass of cyclobutane pyrimidine dimers, a UV- induced lesion.

description: We define and study the Pfaffian state on Riemann surfaces with arbitrary metrics and an inhomogeneous magnetic field and derive its universal transport coefficients. Following a path integral approach, we compute the generating functional which encodes the linear response of the system to a variation of the background metric and the magnetic field and use it to compute the leading and sub-leading corrections to the charge density in a large-$N$ expansion. We also present the first derivation of gravitational anomaly contribution at O$(k^6)$ to the static structure factor for the Pfaffian state in the long wavelength limit.

description: The purpose of this investigation was to characterize 12-hr on-duty, 12-hr off-duty, and 24-hr noise exposures among U.S. Navy aircraft carrier support personnel. Noise dosimetry samples were collected for 47 aircraft carrier support personnel while at sea during airwing carrier qualifications. Leq measurements during 12-hr on-duty, 12-hr off-duty, and over 24-hr periods were compared to Threshold Limit Values. Four similar exposure groups (SEGs) were created based upon departmental assignment and similarity of work tasks: (1) Administration/Religious Ministries/Legal/Training, (2) Combat Systems/Operations, (3) Medical/Dental, and (4) Supply. Equivalent sound level (Leq) measurements in decibels “A” weighted (dBA) were compared to determine significant differences between each group according to 12-hr on-duty, 12-hr off-duty, and 24-hr periods. Mean 24-hr noise levels ranged from 69–88 dBA with 22% exceeding the 80 dBA Threshold Limit Value. Twelve-hr on-duty noise levels ranged from 71–90 dBA with 17% exceeding the 83 dBA 12-hr on-duty Threshold Limit Value. Twelve-hr off-duty noise exposure ranged from 68–84 dBA with 95% exceeding the 70 dBA American Conference of Governmental Industrial Hygienists threshold classified as effective quiet to allow for temporary threshold shift recovery. Welch Analysis of Variance and Dunnett T3 post hoc tests revealed SEG 2 had significantly higher 24-hr noise exposures than SEG 3 (p = 0.019) and SEG 4 (p = 0.045). SEG 2 had significantly higher 12-hr on-duty noise exposure than SEG 3 (p = 0.030). One Way Analysis of Variance revealed no significant differences between 12-hr off-duty noise exposures according to SEG (p = .096). Some aircraft carrier support personnel had 12-hr on-duty and 24-hr noise exposures exceeding Threshold Limit Values with a large proportion exceeding the 70 dBA effective quiet limit during 12-hr off-duty periods. Results suggest personnel that are typically considered low risk for hazardous noise exposure (<85 dBA) during 8-hr shifts may have a greater risk of noise exposure when considering full 12-hr and 24-hr shifts when working and living in close proximity.

description: PROMETHEUS is the Precursor of a new liquid rocket engine family designed for low-cost, flexibility and reusability. This project, undertaken through cooperation between CNES and Ariane Group, entered in ESA Future Launchers Preparatory Programme (FLPP) after the Ministerial Conference in December 2016, with Germany, Italy, Belgium, Sweden and Switzerland joining France in this programme. The aim of project is to design, produce, and test an advanced low-cost 100-tons class LOx/LCH4 reusable Engine. This engine, designed for 1M recurrent cost, targets also flexibility in operation through variable thrust, multiple ignitions, compatibility to main and upper stage operation, and minimized ground operations before and after flight. To reach those ambitious objectives, an extreme design-to-cost approach is mandatory, as well as innovative technologies and advanced industrial capabilities; among the major levers, there are the extensive recourse to Additive Manufacturing for the production of engine components, the introduction of a full electric command system and the on-board rocket engine computer (REEC) for engine management and monitoring. In addition, Prometheus programme promotes the application of agile and frugal methodologies to get maximum profit in product innovation and value creation in operation. Prometheus is key in the effort to prepare competitive future European access to space.

description: Recent results for higher-order corrections to the relation between the vector-boson masses in the Standard Model and Supersymmetry are summarized. In the Standard Model, the Higgs-mass dependence of the two-loop contributions to Delta r is studied. Exact results are given for the Higgs-dependent two-loop corrections associated with the fermions, i.e. no expansion in the top-quark and the Higgs-boson mass is made. The results for the top quark are compared with results of an expansion up to next-to-leading order in the top-quark mass. Agreement is found within 30 % of the two-loop result. In Supersymmetry, the two-loop QCD corrections to the stop- and sbottom-loop contributions to the rho parameter are presented. The two-loop corrections modify the one-loop contribution by up to 30 %; the gluino decouples for large masses. Contrary to the SM case where the QCD corrections are negative and screen the one-loop value, the corresponding corrections in the supersymmetric case are in general positive, increasing the sensitivity in the search for scalar quarks through their virtual effects in high-precision electroweak observables.

description: Several meters below the coastal ocean surface there are areas of high ecological activity that contain thin layers of concentrated motile phytoplankton. Gyrotactic trapping has been proposed as a potential mechanism for layer formation of bottom-heavy swimming algae cells, especially in flows where the vorticity varies linearly with depth (Durham, Stocker & Kessler, Science, vol. 323, 2009, pp. 1067-1070). Using a continuum model for dilute microswimmer suspensions, we report that an instability of a gyrotactically trapped cell-layer can arise in a pressure-driven plane channel flow. The linear stability analysis reveals that the equilibrium cell-layer solution is hydrodynamically unstable due to negative microswimmer buoyancy (i.e. a gravitational instability) over a range of biologically relevant parameter values. The critical cell concentration for this instability is found to be $N_c\simeq 10^4\textrm{cells}/\textrm{cm}^{3}$, a value comparable to the typical maximum cell concentration observed in thin layers. This result indicates that the instability may be a potential mechanism for limiting the layer's maximum cell concentration, especially in regions where turbulence is weak, and motivates the study of its nonlinear evolution, perhaps, in the presence of turbulence.

description: Bisphenol A is a commercially important chemical used to make polycarbonate plastic, epoxy resins, and other specialty products. Despite an extensive body of in vitro, animal and human observational studies on the effects of exposure to bisphenol A, no authoritative bodies in the U.S. have adopted or recommended occupational exposure limits for bisphenol A. In 2017, the National Institute for Occupational Safety and Health published a Draft process for assigning health-protective occupational exposure bands, i.e., an airborne concentration range, to chemicals lacking an occupational exposure limit. Occupational exposure banding is a systematic process that uses both quantitative and qualitative toxicity information on selected health effect endpoints to assign an occupational exposure band for a chemical. The Draft process proposes three methodological tiers of increasing complexity for assigning an occupational exposure band. We applied Tier 1 (based on the Globally Harmonized System of Classification and Labelling) and Tier 2 (based on authoritative sources/reviews) to assign an occupational exposure band to bisphenol A. Under both Tier 1 and 2, the occupational exposure band for bisphenol A was “E” (<0.01 mg/m3), an assignment based on eye damage. “E” is the lowest exposure concentration range, reserved for chemicals with high potential toxicity. If eye damage was excluded in assigning an air concentration exposure range, then bisphenol A would band as “D” (>0.01 to 0.1 mg/m3) under Tier 1 (based on reproductive toxicity and respiratory/skin sensitization) and under Tier 2 (based on specific target organ toxicity-repeated exposure). In summary, Tiers 1 and 2 gave the same occupational exposure band for bisphenol A when eye damage was included (“E”) or excluded (“D”) as an endpoint.

Negative specific heat from non-planar interactions and small black holes in AdS/CFT

Year: 2018
Subjects: subject: High Energy Physics - Theory (hep-th)

description: The gravity side of the gauge/gravity duality predicts the existence of small black holes with negative specific heat. A free theory of strings has a Hagedorn behavior, but it does not lead to negative specific heat. To understand such states one needs to consider a theory of interacting strings. In the dual gauge theory, the string interactions are related to non-planar diagrams. In this paper the simplest gauge matrix model of two free matrices, that has Hagedorn behavior is analyzed in detail. A simple double trace deformation of the Hamiltonian, proportional to square of the free Hamiltonian square with a negative sign that mimics a gravitational attraction is enough to produce states with negative specific heat perturbatively and one can still compute the equation of state relating the entropy and the energy. A more general argument based on non-planar interactions that are random and that grow faster in strength than the energy suggests that states with negative specific heat appear generically.

description: Rift Valley Fever Virus (RVFV) belongs to the genera Phlebovirus in the family Phenuviridae. It is an arbovirus, which can be transmitted by vector mosquitoes. RVFV infects livestock and humans. Infection of pregnant ruminants, including goats, sheep and cattle, results in high abortion rates. Rift Valley fever (RVF) ranges from subclinical to fatal and may cause fetal malformation. In adult sheep, the mortality rate is about 20% while lambs have a higher mortality rate. In humans, the incubation period for the virus is about 6-7 days and RVFV presents with a self-limiting febrile illness which includes malaise, headaches and nausea. In some cases the symptoms may progress to neurological disorders, hemorrhagic fever and/ or ocular disease. RVFV has been classified as a category A pathogen by the National Institute of Allergy and Infectious Diseases (NIAID) as it has the potential for an outbreak and poses the highest threat to national security. It is considered an overlap select agent by the Centers of Disease Control (CDC) and United States Department of Agriculture (USDA). There are currently no FDA approved therapies or vaccines available to the public for RVFV infection. It therefore is important to look at the interaction of viral proteins with host proteins so they can be targeted for therapeutics against RVFV. Gn is one of the glycoproteins of RVFV which plays an important role in the assembly of the virion. The host protein partners of RVFV Gn are largely unknown. Therefore, we aim to identify Gn protein partners using a proteomic-based approach (immunoprecipitation followed by mass spectrometry). To facilitate this analysis and to provide a tool for future research, two V5 tagged MP12 viruses were made namely V5Gn 105 and V5Gn 229 . Our data indicates that the recombinant viruses were functionally similar to the wild type MP12. Our research identified E3 Ubiquitin-protein ligase UBR4 (UBR4) as one of the host protein partners that interacts with RVFV Gn. Knockdown of UBR4 from cells decreases the viral titers from infected cells. Based on our findings that UBR4 knockdown cells have an increased retention of virions, we hypothesize that UBR4 plays a role in the egress of virions from the cells.

description: We report a silica glass nested capillary anti-resonant nodeless fiber with transmission and low bending sensitivity in the mid-infrared around 4000 nm. The fiber is characterized in terms of transmission over 1700-4200 nm wavelengths, revealing a mid-infrared 3500-4200 nm transmission window, clearly observable for a 12 m long fiber. Bending loss around 4000 nm is 0.5 dB/m measured over 3 full turns with 40 mm radius, going up to 5 dB/m for full turns with 15 mm radius. Our results provide experimental evidence of hollow-core silica fibers in which nested, anti-resonant capillaries provide high bend resistance in the mid-infrared. This is obtained for a fiber with large core diameter of over 60 um relative to around 30 um-capillaries in the cladding, which motivates its application in gas fiber lasers or fiber-based mid-infrared spectroscopy of COx or NxO analytes.

description: Today, most separation systems rely on pyrotechnic solutions. This is due to the large flight heritage and simplicity of this technology. However, during recent years, there is an increasing demand from payload suppliers to reduce the amount of shock loads transferred from the launcher in particular during the separation event. In order to achieve this improved payload comfort, RUAG develops a low shock separation system free of pyrotechnics. This paper gives an insight of the ESA funded research and development activities at RUAG Space with respect to new Payload Fairing separation systems.

description: In underdoped cuprates the normal state is highly anomalous and is characterized as a pseudogap phase. The question of how to describe the ``normal'' core of a superconducting vortex is an outstanding open problem. We show that the SU(2) formulation of the t-J model provides a description of the normal state as well as the vortex core. Interestingly, the pseudogap persists inside the core. We also found that it is likely that the core consists of a state which breaks translational symmetry due to the existence of staggered current which generate staggered magnetic field with very slow dynamics. This staggered flux state is likely to be the ground state for magnetic fields higher than $H_{c2}$. Experiments to test this picture are proposed.

description: Macrocyclic glycosides with unique 22-membered dimeric lactone skeleton, are rare occurring natural products. There are only ten compounds reported so far. Herein we reported the isolation and characterisation of five macrocyclic glycosides from Schoenoplectus tabernaemontani, including three new compounds (Schoenopolide A-C, 1–3) and two known ones, Berchemolide (4) and Clemoarmanoside B (5). Their structures were established on the basis of extensive analysis of spectroscopic data. In addition, the anti-oxidative activity of Berchemolide (4) against H2O2-induced of renal tubular epithelial (HK-2) cells was also evaluated.

description: We include the full second-order corrections to the static QCD potential in the analysis of the ttbar threshold cross section. There is an unexpectedly large difference between the QCD potential improved by the renormalization-group equation in momentum space and the potential improved by the renormalization-group equation in coordinate space. This difference remains even at a fairly short distance 1/r \simeq 100 GeV and its origin can be understood within perturbative QCD. We scrutinize the theoretical uncertainties of the QCD potential in relation to the ttbar threshold cross section. In particular there exists a theoretical uncertainty which limits our present theoretical accuracy of the ttbar threshold cross section at the peak to be not better than 6% within perturbative QCD.

description: During the last years, there is an increasing demand from launch primes and space satellite suppliers to improve the payload comfort during flight and increase the payload volume. An improved Fairing Acoustic Protection (FAP) would address both needs. This research investigates a sound absorbing surface in the inner face sheet of the payload fairing sandwich structure. The approach comprises the development of a prediction tool for acoustic impedance and absorption; validated by acoustic testing, such as impedance tube and alpha cabin measurements. Finally, the approach is applied to a real study case with a medium sized class Payload Faring (diameter 2.5 - 4.0 m).

description: Higher education well-being initiatives are in need of analysis within critical scholarship on the neoliberal university, on corporate well-being, and within the field of critical disability studies. Despite the proliferation of well-being initiatives in higher education, which is embedded in systems of neoliberalism and ableism, such an analysis is currently lacking within the aforementioned critical scholarship. Through a multi-method approach that combines content analysis with critical discourse analysis, I examine the ways in which higher education well-being initiatives perpetuate these interlocking hegemonies – neoliberalism and ableism – through their discourses of well-being. Through this analysis, it is evident that higher education well-being initiatives perpetuate notions of individual responsibility and other normative values of neoliberalism, obscuring the harmful systemic conditions in and outside of higher education that impact well-being. These well-being discourses also perpetuate ableist, medicalized notions of well-being and an uncritical, unnuanced pro-cure politics. They also broadly serve to other students, faculty and staff with mental disabilities. While most higher education well-being initiatives across the spectrum of institutions perpetuate neoliberalism and/or ableism in some way, some Historically Black Colleges and Universities and some Tribal Colleges and Universities demonstrate productive approaches to well-being that are rooted in the meeting of tangible community needs. Additionally, at predominantly white institutions, the co-optation of anti-racist liberation movements is evident as an emergent trend in need of further research. Finally, I argue for an embrace of feminist care ethics, conjoined with a political analysis of oppression, resistance and liberation, as a more meaningful and liberatory framework of care in contrast to the normative discourse of well-being predominant on higher education campuses.

description: The recent rapid growth in information technologies such as the internet and mobile phones have added new possibilities for interaction and communication. As groups, movements, and political organizations seek to spread their message to the widest possible audience they have adopted new social media technologies to gather support for their causes. Tibetans and Uyghurs are ethnic groups in China and surrounding countries that contain strong social movements around their cultural identity, geographic location, and political independence. This thesis analyzes how Tibetans and Uyghurs maintain their cultural identity under the umbrella dominance of China through social media use, using the example of more than 70,000 tweets that show how Tibetans and Uyghurs use different actors, strategies, and content used to promote culture and identity.

description: The thermal management of the power electronics cooling in the aeronautical sector is getting more attention in the recent years due to the progressive implementation of electrical systems in the aircrafts. In the context of new semiconductor materials, the use of highly efficient air cooling is again attracting attention. In this regard, the ICOPE Clean Sky project aims to develop new concepts of air cooled heat sinks that incorporate advanced thermal management materials such as Annealed Pyrolytic Graphite and Metal Matrix Composites, namely Aluminium Graphite. Moreover, the work deals with the integration of the newly developed heat sinks into a thermal management bay. This paper is intended to provide the current project development.
Nanoscale Substrate Roughness Hinders Domain Formation in Supported Lipid Bilayers

description: Supported Lipid Bilayers (SLBs) are model membranes formed at solid substrate surfaces. This architecture renders the membrane experimentally accessible to surface sensitive techniques used to study their properties, including Atomic Force Microscopy (AFM), optical fluorescence microscopy, Quartz Crystal Microbalance (QCM) and X-Ray/Neutron Reflectometry, and allows integration with technology for potential biotechnological applications such as drug screening devices. The experimental technique often dictates substrate choice or treatment, and it is anecdotally recognised that certain substrates are suitable for the particular experiment, but the exact influence of the substrate has not been comprehensively investigated. Here, we study the behavior of a simple model bilayer, phase separating on a variety of commonly used substrates, including glass, mica, silicon and quartz, with drastically different results. The distinct micron scale domains observed on mica, identical to those seen in free-floating Giant Unilamellar Vesicles (GUVs), are reduced to nanometer scale domains on glass and quartz. The mechanism for the arrest of domain formation is investigated, and the most likely candidate is nanoscale surface roughness, acting as a drag on the hydrodynamic motion of small domains during phase separation. Evidence was found that the physico-chemical properties of the surface have a mediating effect, most likely due to changes in the lubricating interstitial water layer between surface and bilayer.

description: Ditching is an emergency condition that ends with a controlled impact of the aircraft against water. Ditching analysis has four phases: aircraft conditions before impact; structural response during impact; sliding phase and subsequent floatation. The paper focuses in two of these phases, impact and floatation extensively showing how these two problems are solved in industry. In particular the paper compares three numerical ditching loads methodologies selecting the most suitable. Significant level of test validation using EU funded research program SMAES is shown. The paper ends with conclusions and proposals for further research in ditching.
