title: Konstantinopolis Rus Ressamlar Birliği'nin (1921-1923): Üyeleri Olan Leh Sanatçilarin İstanbul’daki Yaşamı
Creators: name: Aygün, Ekaterina
Publisher: name: Tarih Vakfı, Istanbul
Year: 2023

description: In this article, Ekaterina Aygün delves into the lives and artworks of three artists of Polish descent (Bolesław Cybis, V.P.T./V.P.-Tch./Viktor Prokopowicz-Czartoryski (В.П.-Ч.), Roman Bilinski) who resided and practiced their craft in Constantinople/Istanbul during the 1920s-1930s, following the 1917 revolution in the former Russian Empire. These artists were affiliated with the Union of Russian Painters in Constantinople, each pursuing distinct artistic directions and experiencing unique life trajectories. The article not only explores the similarities and differences among these individuals but also draws comparisons with other émigré artists from the former Russian Empire who were unable to relocate to the newly formed Poland.

description: This work analyzed the effect of the addition of single-wall carbon nanotubes (SWCNTs) on mechanical and electrical properties of cement composites through Molecular Dynamic simulations to contribute self-sensing functionality of structures. To model the atomic structure of the Calcium Silicate Hydrates (C-S-H) gel, Tobermorite 11Å was chosen. SWCNTs type Armchair (3,3) incorporated into the tobermorite structure in four different quantities (0.00%, 1.22%, 2.55% and 4.00% by weight of Tobermorite 11Å) were tested through simulations of applied uniaxial pressure, as well as simulations of applied electrical field, to study the effect of the concentration of carbon nanotubes in the cement composite. Results exhibited a higher tensile strength and a higher Young’s Modulus for the model Tob-CNT(4.00wt%) with values of 14.27 GPa and 165.46 GPa, respectively, while the model Tob-CNT(2.55wt.%) showed a stronger converse piezoelectric response with a calculated of 8.62 .

Effective mass of quasiparticles from thermodynamics

description: We discuss the potential advantages of calculating the effective mass of quasiparticles in the interacting electron liquid from the low-temperature free energy vis-a-vis the conventional approach, in which the effective mass is obtained from approximate calculations of the self-energy, or from a quantum Monte Carlo evaluation of the energy of a variational "quasiparticle wave function". While raw quantum Monte Carlo data are presently too sparse to allow for an accurate determination of the effective mass, the values estimated by this method are numerically close to the ones obtained in previous calculations using diagrammatic many-body theory. In contrast to this, a recently published parametrization of quantum Monte Carlo data for the free energy of the homogeneous electron liquid yields effective masses that considerably deviate from previous calculations and even change sign for low densities, reflecting an unphysical negative entropy. We suggest that this anomaly is related to the treatment of the exchange energy at finite temperature.

description: We demonstrate balanced-detection dual-comb spectroscopy (DCS) using two free-running mechanical sharing dual-comb fiber lasers assisted by an all-computational digital phase correction algorithm. The mutual coherence between the combs allows us perform mode-resolved spectroscopy of gaseous hydrogen cyanide by digitally compensating residual timing and offset frequency fluctuations of the dual-comb signal. Setting the repetition rate difference between the combs to 500 Hz (1.5 kHz) yields more than 2000 resolved radio frequency comb lines after phase correction in a 3-dB bandwidth centered at 1560 nm of wavelength. Through coadding the corrected interferograms (IGMs), we obtain a single time-domain trace with a SNR of 6378 (13960) and 12.64 (13.77) bits of dynamic range in 1 second of averaging. The spectral SNR of the coadded trace reaches 529 (585), corresponding to a figure of merit of SNR of 1.3$\times$10$^6$ (1.4$\times$10$^6$). The measured absorption spectrum of hydrogen cyanide agrees well with the HITRAN database.

Dynamics of electron currents in nanojunctions with time-varying components and interactions

description: We study the dynamics of the electron current in nanodevices where there are time-varying components and interactions. These devices are a nanojunction attached to heat baths and with dynamical electron-phonon interactions and a nanojunction with photon beams incident and reflected at the channel. We use the two-time nonequilibrium Green's functions technique to calculate the time-dependent electron current flowing across the devices. We find that whenever a sudden change occurs in the device, the current takes time to react to the abrupt change, overshoots, oscillates, and eventually settles down to a steady value. With dynamical electron-phonon interactions, the interaction gives rise to a net resistance that reduces the flow of current across the device when a source-drain bias potential is attached. In the presence of dynamical electron-photon interactions, the photons drive the electrons to flow. The direction of flow, however, depends on the frequencies of the incident photons. Furthermore, the direction of electron flow in one lead is exactly opposite to the direction of flow in the other lead thereby resulting in no net change in current flowing across the device.

description: We investigate the possibility to find an ultraviolet completion of the simple extensions of the Standard Model where baryon number is a local symmetry. In the context of such theories one can understand the spontaneous breaking of baryon number at the low scale and the proton stability. We find a simple theory based on SU(4)_C x SU(3)_L x SU(3)_R where baryon number is embedded in a non-Abelian gauge symmetry. We discuss the main features of the theory and the possible implications for experiments. This theory predicts stable colored and/or fractional electric charged fields which can give rise to very exotic signatures at the Large Hadron Collider experiments such as CMS and ATLAS. We further discuss the embedding in a gauge theory based on SU(4)_C x SU(4)_L x SU(4)_R which could define the way to achieve the unification of the gauge interactions at the low scale.

Disorder-enhanced topological protection and universal quantum criticality in a spin-3/2 topological superconductor

description: We study the Majorana surface states of higher-spin topological superconductors (TSCs) that could be realized in ultracold atomic systems or doped semimetals with spin-orbit coupling. As a paradigmatic example, we consider a model with p-wave pairing of spin-3/2 fermions that generalizes ${}^3\text{He-}B$. This model has coexisting linear and cubic dispersing Majorana surface bands. We show that these are unstable to interactions, which can generate a spontaneous surface thermal quantum Hall effect (TQHE). By contrast, nonmagnetic quenched disorder induces a surface conformal field theory (CFT) that is stable against weak interactions: topological protection is enhanced by disorder. Gapless surface states of higher-spin TSCs could therefore be robustly realized in solid state systems, where disorder is inevitable. The surface CFT is characterized by universal signatures that depend only on the bulk topological winding number, and include power-law scaling of the density of states, a universal multifractal spectrum of local density of states fluctuations, and a quantized ratio of the longitudinal thermal conductivity $κ_{xx}$ divided by temperature $T$. By contrast, $κ_{xx}/T$ for the clean surface without TQHE order would diverge as $T \rightarrow 0$. Since disorder stabilizes the conducting Majorana surface fluid and quantizes thermal transport, our results suggest a close analogy between bulk TSCs and the integer quantum Hall effect.

Effects of an Additional Conduction Band on Singlet-Antiferromagnet Competition in the Periodic Anderson Model

description: The competition between antiferromagnetic (AF) order and singlet formation is a central phenomenon of the Kondo and Periodic Anderson Hamiltonians, and of the heavy fermion materials they describe. In this paper, we explore the effects of an additional conduction band on magnetism in these models, and, specifically, on changes in the AF-singlet quantum critical point (QCP) and the one particle and spin spectral functions. To understand the magnetic phase transition qualitatively, we first carry out a self-consistent mean field theory (MFT). The basic conclusion is that, at half-filling, the coupling to the additional band stabilizes the AF phase to larger $f$ $d$ hybridization $V$ in the PAM. We also explore the possibility of competing ferromagnetic phases when this conduction band is doped away from half-filling. We next employ Quantum Monte Carlo (QMC) which, in combination with finite size scaling, allows us to evaluate the position of the QCP using an exact treatment of the interactions. This approach confirms the stabilization of AF order, which occurs through an enhancement of the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction. QMC results for the spectral function $A(\textbf{q},ω)$ and dynamic spin structure factor $χ(\textbf{q},ω)$ yield additional insight into the AF-singlet competition and the low temperature phases.

Precursor of Laughlin state of hard core bosons on a two leg ladder

description: We study hard core bosons on a two leg ladder lattice under the orbital effect of a uniform magnetic field. At densities which are incommensurate with flux, the ground state is a Meissner state, or a vortex state, depending on the strength of the flux. When the density is commensurate with the flux, analytical arguments predict the existence of a ground state of central charge $c = 1$, which displays signatures compatible with the expected Laughlin state at $ν=1/2$. This differs from the coupled wire construction of the Laughlin state in that there exists a nonzero backscattering term in the edge Hamiltonian. We construct a phase diagram versus density and flux in order to delimit the region where this precursor to the Laughlin state is the ground state, by using a combination of bosonization and numerics based on the density matrix renormalization group (DMRG) and exact diagonalization. We obtain the phase diagram from local observables and central charge. We use bipartite charge fluctuations to deduce the Luttinger parameter for the edge Luttinger liquid corresponding to the Laughlin state. The properties studied with local observables are confirmed by the long distance behavior of correlation functions. Our findings are consistent with a calculation of the many body ground state transverse conductivity in a thin torus geometry for parameters corresponding to the Laughlin state. The model considered is simple enough such that the precursor to the Laughlin state could be realized in current ultracold atom, Josephson junction array, and quantum circuit experiments.

description: We present a detailed derivation of the two sum rules relating the spin polarizabilities measured in real, virtual, and doubly-virtual Compton scattering. For example, the polarizability $δ_{LT}$, accessed in inclusive electron scattering, is related to the spin polarizability $γ_{E1E1}$ and the slope of generalized polarizabilities $P^{(M1,M1)1}-P^{(L1,L1)1}$, measured in, respectively, the real and the virtual Compton scattering. We verify these sum rules in different variants of chiral perturbation theory, discuss their empirical verification for the proton, and prospect their use in studies of the nucleon spin structure.

description: We present analytical results at four-loop level for the renormalization constants and anomalous dimensions of an extended QCD model with one coupling constant and an arbitrary number of fermion representations. One example of such a model is the QCD plus gluinos sector of a supersymmetric theory where the gluinos are Majorana fermions in the adjoint representation of the gauge group. The renormalization constants of the gauge boson, ghost and fermion fields are analytically computed as well as those for the ghost-gluon vertex, the fermion-gluon vertex and the fermion mass. All other renormalization constants can be derived from these. Some of these results were already produced in Feynman gauge for the computation of the beta-function of this model, which was recently published. Here we present results for an arbitrary gauge parameter.

description: Supported Ni catalysts (4,5% wt%) using a Ce-Zr oxide (18/82 molar ratio and a ceria rich surface) depicting advanced redox properties, were deposited by washcoating over cordierite honeycombs (230 and 400 cpsi). FIB-STEM unveiled nanostructure details otherwise undistinguishable by conventional techniques. The catalytic performance was evaluated in the dry reforming of methane al 700-900 degree C, using a CH4:CO2 1:1 feddstock, and exploring high Weight Hourly Space Velocity (115-346 L.g-1.h-1). The structured catalyts exhibited better performance than the corresponding powers, reaching values close to rhermodynamics limits for booth reactants conversion and H2/CO ratio, from 750 dgree C, and no deactivation was observed in prolongued experiments (24-48 h). This was related to both the high catalytic efficiency after being deposited with low loading on the cordierite and the intrinsic advantages of the monolithic reactor, like preventing from the kinetic control that operates in powdered samples under high WHSV or limiting the deactivation.

description: In this article, a complete analysis of the three muonic lepton-flavour violating processes $μ\to e γ$, $μ\to 3e$ and coherent nuclear $μ\to e$ conversion is performed in the framework of an effective theory with dimension six operators defined below the electroweak symmetry breaking scale $m_W$. The renormalisation-group evolution of the Wilson coefficients between $m_W$ and the experimental scale is fully taken into account at the leading order in QCD and QED, and explicit analytic and numerical evolution matrices are given. As a result, muonic decay and conversion rates are interpreted as functions of the Wilson coefficients at any scale up to $m_W$. Taking the experimental limits on these processes as input, the phenomenology of the mixing effects is investigated. It is found that a considerable set of Wilson coefficients unbounded in the simplistic tree-level approach are instead severely constrained. In addition, correlations among operators are studied both in the light of current data and future experimental prospects.

description: Formålet med projektet var at undersøge, om vi kunne reducere risikoen for sårinfektion hos ekstremt overvægtige kvinder (BMI ≥30) der fødte ved kejsersnit. Kvinderne blev randomiseret til en almindelig steril bandage eller en vakuumbandage, der blev påsat over kejsersnitssåret umiddelbart efter kejsersnitsoperationen. Bandagen var på tidspunktet for opstart af projektet en relativ ny (CE godkendt) form for vakuumbehandling.. Bandagen anvender undertryk til at fjerne væske og inficeret materiale fra såret samtidig med at undertrykket stimulerer til øget blodgennemstrømningen til sårkanterne.
Da vakuumbandagen er relativ dyr sammenlignet med en standard bandage udførte vi sideløbende en en økonomisk evaluering, hvor vi undersøgte om behandlingen er omkostningseffektiv i forhold til den nuværende behandling. I den økonomiske analyses indsamlede vi informationer om ressourceforbrug og sammenligne med de opnåede sundhedsgevinster.

description: This study aims to explore the association between arginase 1 (ARG1) genetic variation and susceptibility to type 2 diabetes (T2DM) vascular complications, a primary cause of morbidity and mortality in diabetics. ARG1, a risk gene for cardiovascular disease, was identified from GEO datasets GSE22255 and GSE58294. The ENCODE database identified four candidate single-nucleotide polymorphism (SNP) loci. Nine hundred ninety-two T2DM patients underwent SNP genotyping, and relevant biochemical markers were tested. Logistic regression analysis calculated the odds ratio (OR) and 95% confidence interval (CI) between ARG1 SNP and diabetic vascular complications. Out of 985 patients, 250 had CHD, with the TTTG group accounting for 64/250. This group showed a significant reduction in CHD risk (non-TTTG factor-adjusted OR = 1.61, 95% CI: 1.14–2.29, p = 0.008). The combination of the TTTG group, age, central obesity, and hypertension better predicted CHD risk (Area under the curve = 0.72, p < 0.001). ARG1 polymorphisms significantly impact vascular complications in T2DM patients, implying that ARG1 genetic variation may be a potential prevention and treatment target. ChiCTR1800015661

description: We perform a thorough study of the thermodynamic properties of a class of Lovelock black holes with conformal scalar hair arising from coupling of a real scalar field to the dimensionally extended Euler densities. We study the linearized equations of motion of the theory and describe constraints under which the theory is free from ghosts/tachyons. We then consider, within the context of black hole chemistry, the thermodynamics of the hairy black holes in the Gauss-Bonnet and cubic Lovelock theories. We clarify the connection between isolated critical points and thermodynamic singularities, finding a one parameter family of these critical points which occur for well-defined thermodynamic parameters. We also report on a number of novel results, including `virtual triple points' and the first example of a `$λ$-line'---a line of second order phase transitions---in black hole thermodynamics.

The Width Distribution of Loops and Strands in the Solar Corona -- Are we Hitting Rock Bottom ?

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

description: In this study we analyze {\sl Atmospheric Imaging Assembly (AIA)} and Hi-C images in order to investigate absolute limits for the finest loop strands. We develop a model of the occurrence-size distribution function of coronal loop widths, characterized by a lower limit of widths $w_{min}$, a peak width $w_p$, a peak occurrence number $n_p$, and a power law slope $a$. Our data analysis includes automated tracing of curvi-linear features with the OCCULT-2 code, automated sampling of the cross-sectional widths of coronal loops, and fitting of the theoretical size distribution to the observed distribution. With Monte-Carlo simulations and variable pixel sizes $Δx$ we derive a first diagnostic criterion to discriminate whether the loop widths are unresolved $(w_p/Δx \approx 2.5\pm0.2)$, or fully resolved (if $w_p/Δx > 2.7$). For images with resolved loop widths we can apply a second diagnostic criterion that predicts the lower limit of loop widths, $w_{min} \approx 3 (Δx_{crit}-0.37")$ as a function of the critical resolution $Δx_{crit}$. We find that the loop widths are marginally resolved in AIA images, but are fully resolved in Hi-C images, where our model predicts a lower limit of loop widths at $w_{min} \approx 100$ km and a most frequent (peak) value at $w_p \approx 300$ km, in agreement with recent results of Brooks et al. This result agrees with the statistics of photospheric granulation sizes and thus supports coronal heating mechanisms operating on the macroscopic scale of photospheric magneto-convection, rather than nanoflare heating models with unresolved microscopic scales.

description: We construct two new SL(2,Z) invariant vacua of type IIB string theory which are bound states of $(p,q)$ strings with $(m,n)$ 5-branes, written as ((F, D1), (NS5, D5)) and preserve 1/4 of the full space-time supersymmetries. For the first case, the strings live inside the 5-brane world-volume and in the second case the strings are perpendicular to the 5-brane world-volume. In the first case, naively one would expect an attractive interaction between the strings and the 5-branes due to attractive force between F and D5 and also between D1 and NS5. We find that 1/4 BPS bound state exists only when the vacuum moduli satisfy certain condition which is found to be consistent with the no-force condition between the branes. No such complication arises for the second case. The tension formulae and the various other descendant states which can be obtained by the application of T-duality for both these bound states are discussed.

description: The Batch Markov Modulated Poisson Process (BMMPP) is a subclass of the versatile Batch Markovian Arrival process (BMAP) which has been proposed for the modeling of dependent events occurring in batches (as group arrivals, failures or risk events). This paper focuses on exploring the possibilities of the BMMPP for the modeling of real phenomena involving point processes with group arrivals. The first result in this sense is the characterization of the two-state BMMPP with maximum batch size equal to K, the BMMPP2(K), by a set of moments related to the inter-event time and batch size distributions. This characterization leads to a sequential fitting approach via a moments matching method. The performance of the novel fitting approach is illustrated on both simulated and a real teletraffic data set, and compared to that of the EM algorithm. In addition, as an extension of the inference approach, the queue length distributions at departures in the queueing system BMMPP/M/1 is also estimated.

description: The objective of this study was to investigate the prognostic significance of the preoperative serum albumin-bilirubin (ALBI) score in patients with colorectal cancer (CRC). Preoperative ALBI data from 1506 CRC patients were categorized into high-value and low-value groups, and the clinicopathological characteristics of these groups were compared. A Cox proportional hazards regression model was employed to investigate the risk factors associated with distant metastasis. The Kaplan-Meier method and log-rank test were utilized to analyze the relationship between ALBI scores and 5-year distant metastasis-free survival (DMFS). The incidence of distant metastasis in group B (ALBI ≥ −2.4) was significantly higher at 28.81% compared to group A (ALBI < −2.4), which had an incidence of 23.36% (p = 0.018). ALBI score ≥ −2.4 was identified as an independent risk factor for postoperative distant metastasis of CRC (HR = 1.251, 95%CI: 1.021–1.533, p = 0.031). The incidence of 5-year DMFS was significantly lower in the ALBI ≥ −2.4 group compared to that observed in the ALBI < −2.4 group (χ2 = 5.97, p = 0.015, log-rank test). The ALBI score of ≥ −2.4 emerges as an independent risk factor for the occurrence of distant metastases following CRC surgery. This study analyzed the association between the ALBI score (an index of liver function) and postoperative distant metastasis in 1506 colorectal cancer (CRC) patients. Distant metastasis is where cancer has spread from the original tumor to other organs or lymph nodes. Patients with a high ALBI score (≥-2.4) had a significantly higher incidence of distant metastasis and a substantially lower 5-year distant metastasis-free survival (DMFS) compared to those with a low ALBI score (<-2.4). This is the first report linking the ALBI score to distant metastases, potentially guiding patient management.

description: Dry Dilution Refrigerators (DDR) based on pulse tube cryo-coolers have started to replace Wet Dilution Refrigerators (WDR) due to the ease and low cost of operation. However these advantages come at the cost of increased vibrations, induced by the pulse tube. In this work, we present the vibration measurements performed on three different commercial DDRs. We describe in detail the vibration measurement system we assembled, based on commercial accelerometers, conditioner and DAQ, and examined the effects of the various damping solutions utilized on three different DDRs, both in the low and high frequency regions. Finally, we ran low temperature, pseudo-massive (30 and 250 g) germanium bolometers in the best vibration-performing system under study and report on the results.

description: Aim: To investigate the association between serum complement 3 and 4 (C3 and C4) levels and clinical characteristics in osteoarthritis (OA) patients. Methods: This retrospective study included 361 OA patients divided into groups based on complement levels. Clinical data and laboratory test results, including C3, C4, ESR and CRP levels, were analyzed using non-parametric tests, Spearman correlation and multivariate regression. Results: The AC-OA group had lower PA, C3, C4, ESR, CRP and IgA levels compared with controls. C3 levels were positively correlated with ESR (r = 0.260, p < 0.001) and CRP (r = 0.243, p < 0.001). C4 levels also correlated with ESR (r = 0.175, p = 0.001) and CRP (r = 0.263, p < 0.001) and were significantly associated with the number of affected joints. Conclusion: Serum C4 levels are effective indicators of disease activity in OA, particularly in terms of joint involvement and CRP levels, while C3 levels showed no significant association. These findings suggest a potential role for C4 in predicting OA activity. Association of serum complement levels with clinical characteristics This study found a positive correlation between serum complements (C3 and C4) and OA patients' clinical characteristics and inflammatory activity indicators. Proposed tool for predicting OA activity The study proposes a convenient tool for predicting OA activity based on C3 and C4 levels. Clinical characteristics of patients with abnormal complement levels Changes related to complements and inflammatory markers such as ESR and CRP may play an essential role in the pathogenesis of AC-OA (comparison of clinical characteristics of OA patients with abnormal complement levels). Correlation between serum complements and disease activity indicators Complement levels are positively correlated with disease activity indicators of OA such as ESR and CRP (correlation between serum complements and disease activity indicators in OA patients). Association of C4 levels with the number of affected joints Lower C4 levels are more strongly associated with fewer affected joints (correlation between serum complement levels and the number of affected joints in OA patients). Types of joints affected by OA There is no significant association between C4 levels and the types of joints affected in OA patients (Correlation between serum complement levels and types of affected joints in OA patients). Effect of confounding factors on ESR Levels After excluding confounding factors, the significance of the correlation between C3 and C4 levels and ESR levels is reduced (Correlation between serum complement levels and ESR levels in OA patients). Association between C4 and CRP Levels C4 levels positively correlate with CRP levels (correlation between serum complement levels and CRP levels in OA patients).

description: Using HST, we identify circumnuclear ($100$-$500$ pc scale) structures in nine new H$_2$O megamaser host galaxies to understand the flow of matter from kpc-scale galactic structures down to the supermassive black holes (SMBHs) at galactic centers. We double the sample analyzed in a similar way by Greene et al. (2013) and consider the properties of the combined sample of 18 sources. We find that disk-like structure is virtually ubiquitous when we can resolve $<200$ pc scales, in support of the notion that non-axisymmetries on these scales are a necessary condition for SMBH fueling. We perform an analysis of the orientation of our identified nuclear regions and compare it with the orientation of megamaser disks and the kpc-scale disks of the hosts. We find marginal evidence that the disk-like nuclear structures show increasing misalignment from the kpc-scale host galaxy disk as the scale of the structure decreases. In turn, we find that the orientation of both the $\sim100$ pc scale nuclear structures and their host galaxy large-scale disks is consistent with random with respect to the orientation of their respective megamaser disks.

description: The event horizon of black holes and white holes can be achieved in the context of analogue gravity. It was proven for a sonic case that if these two horizons are close to each other their dynamics resemble a laser, a black hole laser, where the analogue of Hawking radiation is trapped and amplified. Optical analogues are also very successful and a similar system can be achieved there. In this work we develop the theory of optical black hole lasers and prove that the amplification is also possible. Then, we study the optical system by determining the forward propagation of modes, obtaining an approximation for the phase difference which governs the amplification, and performing numerical simulations of the pulse propagation of our system.

Generalized coherent states satisfying the Pauli principle in a nuclear cluster model

description: We propose a new basis state, which satisfies the Pauli principle in the nuclear cluster model. The basis state is defined as the generalized coherent state of the harmonic oscillator wave function using a pair of the creation operators and is orthogonal to the Pauli-forbidden states having smaller quanta. In the coherent basis state, the range parameter is changeable and controls the radial dilation. This property is utilized for the precise description of the relative motion between nuclear clusters. We show the reliability of this framework for the $2α$ system of $^8$Be in the semi-microscopic orthogonality condition model. We obtain the resonances and non-resonant continuum states of $2α$ with complex scaling. The resonance solutions and the phase shifts of the $α$-$α$ scattering agree with those using the conventional projection operator method to remove the Pauli-forbidden states. We further discuss the extension of the present framework to the multi-$α$ cluster systems using the SU(3) wave functions.
