Distribution in Türkiye: Adana, Antalya, Burdur, Denizli, İçel, Karaman, Osmaniye (Özdikmen, 2022)
Male genitalia (Fig. 4 G): Total length of aedeagus 3.1 mm. Median lobe is strongly curved especially along the struts in lateral view, median struts separated up to medio-proximal. Median lobe slightly outward proximally, with wavy lateral edges. Median lobe with a triangular apex, an enlarged median orifice, and triangular edge of the median foramen. Tegmen with a vague roof part. Lateral lobes of tegmen converged at a slight angle inward, fingerlike shaped, 4.58 times longer than width; with orangeish hairs at apex. Ring part basally separated, parallel from base to distal, curved distally.
Spermatheca (Fig. 3 c): Spermatheca 0.25 mm, moderately chitinized; body convex basally, curving inward apically.
Stenurella bifasciata (Müller, 1776) was the most abundant species collected, with 175 individuals followed by Pseudovadonia livida Danilevsky, 2013) with 137 individuals. Other abundant species included Stictoleptura fulva with 75 individuals. The species with the fewest individuals were Anastrangalia sanguinolenta, Leptura aurulenta, and Stictoleptura rufa (Table 2).
Ecological studies on habitat preferences and sampling methods (Table 2), revealed that Rhv-In (Herbaceous vegetation near fields and roads-Insect net) had the greatest species diversity, followed by Shp-In (Herbaceous vegetation near streams-Insect net), F-Pt (Forest-Pheromone trap)and Fghv-In (Forest ground herbaceous vegetation-Insect net) (Fig. 7).
Field studies were conducted from April to October, with additional specimens collected by various researchers. When analyzed by month; 11 species were recorded in May, 14 in June, 16 in July, and two in August (Fig. 8). Lepturini species appear to be are most active in May, June, and July, with the fewest species collected in August, likely due to rising temperatures. One species was recorded only in May, three only in June, and four only in July (Table 2).
Specimens were also divided by altitude (250-meter intervals) The most species were recorded between 751– 1000m (13 species), followed by 1251–1500m (12 species), 251-500m, 501–750m, and 1001–1250m (11 species each), 0–250m (6 species), 1501–1750m (3 species), and 1751–2000m (1 species) (Fig. 9).

description: In this work, we propose a method for the compression of the coupling matrix in volume\hyp surface integral equation (VSIE) formulations. VSIE methods are used for electromagnetic analysis in magnetic resonance imaging (MRI) applications, for which the coupling matrix models the interactions between the coil and the body. We showed that these effects can be represented as independent interactions between remote elements in 3D tensor formats, and subsequently decomposed with the Tucker model. Our method can work in tandem with the adaptive cross approximation technique to provide fast solutions of VSIE problems. We demonstrated that our compression approaches can enable the use of VSIE matrices of prohibitive memory requirements, by allowing the effective use of modern graphical processing units (GPUs) to accelerate the arising matrix\hyp vector products. This is critical to enable numerical MRI simulations at clinical voxel resolutions in a feasible computation time. In this paper, we demonstrate that the VSIE matrix\hyp vector products needed to calculate the electromagnetic field produced by an MRI coil inside a numerical body model with $1$ mm$^3$ voxel resolution, could be performed in $\sim 33$ seconds in a GPU, after compressing the associated coupling matrix from $\sim 80$ TB to $\sim 43$ MB.

description: This paper is devoted to the study of leading twist light cone wave function of $η_c$ meson. The moments of this wave function have been calculated within three approaches: potential models, nonrelativistic QCD and QCD sum rules. Using the results obtained within these approaches the model for the light cone wave function of leading twist has been proposed. Being scale dependent light cone wave function has very interesting properties at scales $μ> m_c$: improvement of the accuracy of the model, appearance of relativistic tail and violation of nonrelativistic QCD velocity scaling rules. The last two properties are the properties of real leading twist light cone wave function of $η_c$ meson.

description: We study a purely leptonic signature of the Randall-Sundrum scenario with Standard Model fields in the bulk at LHC: the contribution from the exchange of Kaluza-Klein (KK) excitations of gauge bosons to the clear Drell-Yan reaction. We show that this contribution is detectable (even with the low luminosities of the LHC initial regime) for KK masses around the TeV scale and for sufficiently large lepton couplings to KK gauge bosons. Such large couplings can be compatible with ElectroWeak precision data on the Zff coupling in the framework of the custodial O(3) symmetry recently proposed, for specific configurations of lepton localizations (along the extra dimension). These configurations can simultaneously reproduce the correct lepton masses, while generating acceptably small Flavour Changing Neutral Current (FCNC) effects. This LHC phenomenological analysis is realistic in the sense that it is based on fermion localizations which reproduce all the quark/lepton masses plus mixing angles and respect FCNC constraints in both the hadron and lepton sectors.

description: Simulating the full dynamics of a quantum field theory over a wide range of energies requires exceptionally large quantum computing resources. Yet for many observables in particle physics, perturbative techniques are sufficient to accurately model all but a constrained range of energies within the validity of the theory. We demonstrate that effective field theories (EFTs) provide an efficient mechanism to separate the high energy dynamics that is easily calculated by traditional perturbation theory from the dynamics at low energy and show how quantum algorithms can be used to simulate the dynamics of the low energy EFT from first principles. As an explicit example we calculate the expectation values of vacuum-to-vacuum and vacuum-to-one-particle transitions in the presence of a time-ordered product of two Wilson lines in scalar field theory, an object closely related to those arising in EFTs of the Standard Model of particle physics. Calculations are performed using simulations of a quantum computer as well as measurements using the IBMQ Manhattan machine.

The analysis makes use of 324 million e+e- --> BB events recorded by the BaBar experiment at the PEP-II e+e- storage ring. By analyzing the pi+pi-pi0 Dalitz plot distribution and the B+/- --> D(pipipi0)K+/- branching fraction and decay rate asymmetry, we calculate parameters related to the phase gamma of the CKM unitarity triangle. We also measure the magnitudes and phases of the components of the D0 --> pi+pi-pi0 decay amplitude.

description: We present a search for new planetary-mass members of nearby young moving groups (YMGs) using astrometry for 694 T and Y dwarfs, including 447 objects with parallaxes, mostly produced by recent large parallax programs from UKIRT and Spitzer. Using the BANYAN $Σ$ and LACEwING algorithms, we identify 30 new candidate YMG members, with spectral types of T0$-$T9 and distances of $10-43$ pc. Some candidates have unusually red colors and/or faint absolute magnitudes compared to field dwarfs with similar spectral types, providing supporting evidence for their youth, including 4 early-T dwarfs. We establish one of these, the variable T1.5 dwarf 2MASS J21392676$+$0220226, as a new planetary-mass member ($14.6^{+3.2}_{-1.6}$ M$_{\rm Jup}$) of the Carina-Near group ($200\pm50$ Myr) based on its full six-dimensional kinematics, including a new parallax measurement from CFHT. The high-amplitude variability of this object is suggestive of a young age, given the coexistence of variability and youth seen in previously known YMG T dwarfs. Our four latest-type (T8$-$T9) YMG candidates, WISE J031624.35$+$430709.1, ULAS J130217.21$+$130851.2, WISEPC J225540.74$-$311841.8, and WISE J233226.49$-$432510.6, if confirmed, will be the first free-floating planets ($\approx2-6$ M$_{\rm Jup}$) whose ages and luminosities are compatible with both hot-start and cold-start evolutionary models, and thus overlap the properties of the directly-imaged planet 51 Eri b. Several of our early/mid-T candidates have peculiar near-infrared spectra, indicative of heterogenous photospheres or unresolved binarity. Radial velocity measurements needed for final membership assessment for most of our candidates await upcoming 20$-$30 meter class telescopes. In addition, we compile all 15 known T7$-$Y1 benchmarks and derive a homogeneous set of their effective temperatures, surface gravities, radii, and masses.

Semiclassical Quantisation of Finite-Gap Strings

Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We perform a first principle semiclassical quantisation of the general finite-gap solution to the equations of a string moving on R x S^3. The derivation is only formal as we do not regularise divergent sums over stability angles. Moreover, with regards to the AdS/CFT correspondence the result is incomplete as the fluctuations orthogonal to this subspace in AdS_5 x S^5 are not taken into account. Nevertheless, the calculation serves the purpose of understanding how the moduli of the algebraic curve gets quantised semiclassically, purely from the point of view of finite-gap integration and with no input from the gauge theory side. Our result is expressed in a very compact and simple formula which encodes the infinite sum over stability angles in a succinct way and reproduces exactly what one expects from knowledge of the dual gauge theory. Namely, at tree level the filling fractions of the algebraic curve get quantised in large integer multiples of hbar = 1/lambda^{1/2}. At 1-loop order the filling fractions receive Maslov index corrections of hbar/2 and all the singular points of the spectral curve become filled with small half-integer multiples of hbar. For the subsector in question this is in agreement with the previously obtained results for the semiclassical energy spectrum of the string using the method proposed in hep-th/0703191. Along the way we derive the complete hierarchy of commuting flows for the string in the R x S^3 subsector. Moreover, we also derive a very general and simple formula for the stability angles around a generic finite-gap solution. We also stress the issue of quantum operator orderings since this problem already crops up at 1-loop in the form of the subprincipal symbol.

In doing so, we highlight several deficiencies in defending against XSW. Using this real-world contemporary example as motivation, we introduce a guideline for more secure XML signature processing that provides practitioners with easier access to the effective countermeasures identified in the current state of research.

description: We discuss the existence of the light scalar meson K^*_0(800) (also called kappa) in a rigorous way, by showing the presence of a pole in the pi K --> pi K amplitude on the second Riemann sheet. For this purpose, we study the domain of validity of two classes of Roy-Steiner representations in the complex energy plane. We prove that one of them is valid in a region sufficiently broad in the imaginary direction. From this representation, we compute the l=0 partial wave in the complex plane with neither additional approximation nor model dependence, relying only on experimental data. A scalar resonance with strangeness S=1 is found with the following mass and width: E_kappa = 658 \pm 13 MeV and Gamma_kappa = 557 \pm 24 MeV.

description: We study the growth of bipartite networks in which the number of nodes in one of the partitions is kept fixed while the other partition is allowed to grow. We study random and preferential attachment as well as combination of both. We derive the exact analytical expression for the degree-distribution of all these different types of attachments while assuming that edges are incorporated sequentially, i.e., a single edge is added to the growing network in a time step. We also provide an approximate expression for the case when more than one edge are added in a time step. We show that depending on the relative weight between random and preferential attachment, the degree-distribution of this type of network falls into one of four possible regimes which range from a binomial distribution for pure random attachment to an u-shaped distribution for dominant preferential attachment.

The considered model is the continuous one defined in Janson 2000. An ${\ell}$-component is a connected component with ${\ell}$ edges more than vertices. $\ell$ is also called the \textit{excess} of such component. As our main result, we show that when $\ell$ and ${n \over \ell}$ are both large, the expected number of vertices that ever belong to an $\ell$-component is about ${12}^{1/3} {\ell}^{1/3} n^{2/3}$. We also obtain limit theorems for the number of creations of $\ell$-components.

The human melanoma-associated antigen p97 is attached to the plasma membrane by a glycosyl-phosphatidylinositol anchor
Creators: name: Food, Michael Robert
Publisher: name: University of British Columbia
Year: 2008

description: Melanotransferrin, or p97 is a cell surface glycoprotein which was first described as a marker antigen for human melanoma cells. Although p97 has a high level of amino acid sequence homology to human serum transferrin and lactoferrin its function has not yet been determined. One feature that distinguishes p97 from the other members of the transferrin family is the presence of a stretch of 24 hydrophobic amino acids at the C-terminus. In all previous studies, this sequence was thought to form a proteinacious transmembrane domain. In this study, however, sensitivity to bacterial phosphatidylinositol-specific phospholipase C, biosynthetic labelling with [³H]-ethanolamine, and partitioning in Triton X-114, were used to establish that p97 is expressed at the cell surface as a glycosyl-phosphatidylinositol anchored protein. As well, this anchor was shown to be present in p97 on human tumor lines and it apparently confers no special intracellular transport properties on the molecule. These findings raise important questions about the function of p97 and the possible involvement of this protein in a cellular iron uptake system that is independent from the transferrin/ transferrin receptor system.

Short-scalelength plasma spectroscopy
Creators: name: Forsman, Andrew
Publisher: name: University of British Columbia
Year: 2008

description: Traditional x-ray plasma spectroscopy techniques employ long scalelength laser-produced plasmas in an attempt to moderate the density and temperature gradients present in the ablation plasma. These approaches have the disadvantages that the large plasma may lead to significant opacity effects, lasers having substantial power must be used and numerical simulations of the laser-produced plasma frequently must be used to interpret the data. As an alternative technique the use of short-scalelength plasmas as sources for x-ray spectroscopy have been investigated. High-resolution silicon K-shell spectra from a short-scalelength, laser-produced plasma have been obtained in temporally and spatially integrated measurements. Density-sensitive line-intensity ratios of the helium like satellites and that of the lithium-like satellites are employed simultaneously with temperature-sensitive line-intensity ratios between the helium and lithium-like satellites to assess their diagnostic value. A constant, uniform plasma model is used to interpret the data. It appears that the emission of dielectronic satellite lines is dominated by a region with a relatively well-defined density and temperature in the ablation zone.

ERP correlates of interference and inhibitory control in adults with high and low-level subclinical ADHD symptoms
Creators: name: Hislop, IM
Publisher: name: University of Tasmania

description: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by elevated rates of inattention, impulsivity, and hyperactivity in child and adult populations. ADHD research has identified a specific link between ADHD diagnosis and impairment in the executive functions of attention, specifically within interference and inhibitory control. The current study aimed to enhance the existing body of literature by observing an adult sample with high and low subclinical levels of ADHD symptomology, a deviation from the established child-dominant, clinically diagnosed samples. The current study incorporated the use of electroencephalography (EEG) to record and compare the neural and behavioural correlates of individuals during engagement in a novel hybrid Flanker Go/NoGo task aimed at eliciting interference and inhibitory control processes simultaneously. High and low ADHD symptom groups were established on the basis of Adult ADHD Self-Report Scale (ASRS) v1.1 scores and compared across the behavioural variables of reaction time and accuracy. Neural differences were recorded across the frontal FZ and FCz electrodes with the N2 EEG component used as the neurological measure of interference and inhibitory control. Results identified no statistically significant differences across high and low ADHD symptom groups in behavioural or neural correlates. The findings of the current study were inconsistent with prior child and male-dominated research, indicating future investigations may benefit from further exploring the neural and behavioural correlates of adult and female ADHD presentations.

description: We study a class of gauge groups that can automatically yield a perturbatively exact Peccei-Quinn symmetry, and we outline a model in which the axion quality problem is solved at all operator dimensions. Gauge groups belonging to this class can also enforce and protect accidental symmetries of the clockwork type, and we present a toy model where an `invisible' axion arises from a single breaking of the gauge and global symmetries.

description: We study circle compactifications of 6d superconformal field theories giving rise to 5d rank 1 and rank 2 Kaluza-Klein theories. We realise the resulting theories as M-theory compactifications on local Calabi-Yau 3-folds and match the prepotentials from geometry and field theory. One novelty in our approach is that we include explicit dependence on bare gauge couplings and mass parameters in the description which in turn leads to an accurate parametrisation of the prepotential including all parameters of the field theory. We find that the resulting geometries admit "fibre-base" duality which relates their six-dimensional origin with the purely five-dimensional quantum field theory interpretation. The fibre-base duality is realised simply by swapping base and fibre curves of compact surfaces in the local Calabi-Yau which can be viewed as the total space of the anti-canonical bundle over such surfaces. Our results show that such swappings precisely occur for surfaces with a zero self-intersection of the base curve and result in an exchange of the 6d and 5d pictures.

description: Deuteron and anti-deuteron production in Z decays has been observed in the ALEPH experiment at LEP. The production rate of anti-deuterons is measured to be 5.9+-1.8+-0.5 10^-6 per hadronic Z decay in the anti-deuteron momentum range 0.62 to 1.03 GeV/c. The coalescence parameter B_2, which characterizes the likelihood of anti-deuteron production, is measured to be 0.0033+-0.0013 GeV^2 in Z dedays. These measurements indicate that the production of anti-deuterons is suppressed in e+e- collisions compared to pp and photoproduction collisions.

description: It is uncertain whether or not low-mass Population III stars ever existed. While limits on the number density of Population III stars with $M_{\ast} \approx 0.8~M_{\odot}$ have been derived using Sloan Digital Sky Survey (SDSS) data, little is known about the occurrence of Population III stars at lower masses. In the absence of reliable parallaxes, the spectra of metal-poor main sequence (MPMS) stars with $M_{\ast} \lesssim 0.8~M_{\odot}$ can easily be confused with cool white dwarfs. To resolve this ambiguity, we present a classifier that differentiates between MPMS stars and white dwarfs based on photometry and/or spectroscopy without the use of parallax information. We build and train our classifier using state-of-the-art theoretical spectra and evaluate it on existing SDSS-based classifications for objects with reliable Gaia DR2 parallaxes. We then apply our classifier to a large catalog of objects with SDSS photometry and spectroscopy to search for MPMS candidates. We discover several previously unknown candidate extremely metal-poor (EMP) stars and recover numerous confirmed EMP stars already in the literature. We conclude that archival SDSS spectroscopy has already been exhaustively searched for EMP stars. We predict that the lowest-mass primordial-composition stars will have redder optical-to-infrared colors than cool white dwarfs at constant effective temperature due to surface gravity-dependent collision-induced absorption from molecular hydrogen. We suggest that the application of our classifier to data produced by next-generation spectroscopic surveys will set stronger constraints on the number density of low-mass Population III stars in the Milky Way.

It's Cloud's Illusions I Recall: Mixing Drives the Acceleration of Clouds from Ram Pressure Stripped Galaxies

description: Ram Pressure Stripping can remove gas from satellite galaxies in clusters via a direct interaction between the intracluster medium (ICM) and the interstellar medium. This interaction is generally thought of as a contact force per area, however we point out that these gases must interact in a hydrodynamic fashion, and argue that this will lead to mixing of the galactic gas with the ICM wind. We develop an analytic framework for how mixing is related to the acceleration of stripped gas from a satellite galaxy. We then test this model using three "wind-tunnel" simulations of Milky Way-like galaxies interacting with a moving ICM, and find excellent agreement with predictions using the analytic framework. Focusing on the dense clumps in the stripped tails, we find that they are nearly uniformly mixed with the ICM, indicating that all gas in the tail mixes with the surroundings, and dense clumps are not separate entities to be modeled differently than diffuse gas. We find that while mixing drives acceleration of stripped gas, the density and velocity of the surrounding wind will determine whether the mixing results in the heating of stripped gas into the ICM, or the cooling of the ICM into dense clouds.

description: Unerwünschte Berührungen und Kollisionen zwischen benachbarten Schrauben sind technische Probleme mit entsprechender Sicherheitsrelevanz. Sie werden durch Lageimperfektionen verursacht, die sowohl systematisch als auch zufällig beim Einschrauben entstehen. Um Ursachen von solchen Lageimperfektionen zu untersuchen, wurden fast 1200 Einschraubversuche in BSH, BSP und FSH durchgeführt. Für variierende Untersuchungsparameter wurde die Abweichung zwischen dem geplanten und dem tatsächlichen Austrittspunkt der Schrauben ermittelt. Die Ergebnisse belegen, dass der Winkel α zwischen Schraubenachse und Faserrichtung des Holzes, die Schlankheit sowie die Spitzenausführung einer Schraube und der Einschraubwinkel die Ausprägung von Lageimperfektionen signifikant beeinflussen. Ferner wurden Methoden zur Minimierung von Lageimperfektionen in fast 600 Einschraubversuchen untersucht. Präzise hergestellte Pilotbohrungen erwiesen sich dabei als wirksames Mittel zur Reduzierung von Lageimperfektionen.
title: Tn3 resolvase-catalysed recombination: Assembly and activation of the site I synapse
Creators: name: Olorunniji, Femi John
Publisher: name: University of Glasgow
Year: 2006

description: The assembly and catalytic activation of the site I synapse in resolvase-catalysed recombination was investigated by a combination of mutagenesis and chemical modification of DNA substrates. The binding and catalytic properties of activated Tn3 resolvase mutants were compared with those of wild-type resolvase with the aim of understanding how activating mutations deregulate site I synapsis and catalysis. The findings indicate that structural changes in the resolvase-site I dimer complex are important for the formation of a stable site I synapse. Efficient catalysis of site I x site I recombination by activated resolvase mutants is highly correlated with formation of stable site I synapse in polyacrylamide bandshift assays. Conserved residues that are presumed to form the active site of resolvase were mutated in activated mutants of Tn3 resolvase, and the binding, synapsis and catalytic properties of the mutant resolvases were characterised. Certain mutations in putative active site residues of resolvase resulted in decrease in the yield and/or stability of the site I synapse, while mutations in another set of residues in the putative active site destabilised the dimer complex and stabilised the site I synapse. These results suggest a role for the active site in site I synapsis. Methylphosphonate replacements of phosphodiester groups close to the scissile position in site I show that direct contact of resolvase with the centre of site I is important for synapsis, but not necessarily for binding. Such contacts are not seen in the published structures of the site 1 synapse. The apparent lack of contact between catalytic residues and the DNA in cocrystal resolvase structures suggests that the engagement of catalytic residues with the substrate is at the point of catalytic activation. The results of site I cleavage experiments with resolvase mutants show that while several conserved residues are important for the recombination activity of resolvase, only a few of these are essential for the activation of the catalytic process. The effects of methylphosphonate substitution at the phosphate immediately 3' to the scissile position on site I cleavage suggests a catalytic role for this phosphate, such as recruitment of positively charged catalytic residues into the active site prior to catalysis.

description: This thesis showcases the donor-site engineering in PdII-mediated coordination complexes, yielding distinctive supramolecular architectures, including the molecular cage, bowl, ring and capsule focuses on the donor-site-controlled self-assembly of supramolecules as well as their distinct fullerene binding abilities. Afterwards, the assembled cage is able to selectively bind C60 from fullerene soot, and develops into a recyclable system of C60 purification controlled by solvent effects. The novel bowl structure is not only found to serve as a supramolecular protecting group, which allows selective mono-functionalization of its guest, but is also capable of being connected by a second ligand to hierarchically assemble into a molecular capsule which can accommodate two fullerene molecules within its inner cavity. In addition, a non-traditional nitrogen donor, namely naphthyridine, is shown to manifest a dislocated arrangement in the PdII coordination sphere owing to the repulsive effect between adjacent electron-pairs. A synergy between quinoline donors and naphthyridine donors as well as template effect of guests is further exploited to generate heteroleptic cages. At last, a newly designed fullerene-based ligand can assemble with PdII into a coordination cage bearing four fullerene molecules in the periphery. All compounds have been fully characterized by multiple analytic techniques, such as NMR spectroscopy, mass spectrometry and single crystal X-ray structural analysis.
