description: This study analyzed 34 canned fish products, including 28 tuna specimens, 3 salmon specimens, 1 mackerel specimen, and 1 anchovy specimen, from 13 different brands purchased in Türkiye. The study aimed to determine metal/metalloid levels in canned fish and potential health risks for both children and adult consumers. The metal/metalloid levels in the samples were determined using an Inductively Coupled Plasma–Mass Spectrometer (ICP–MS), with the range of levels found as follows (mg/kg, ww): Fe (12.12–101.4), Cu (2.19–11.68), Zn (4.06–33.56), Se (0.24–10.74), Al (1.41–14.45), Cr (0.06–4.08), Pb (0.10–0.43), Cd (0.001–0.110), and As (0.01–0.13). Estimated weekly intake (EWI) levels were found that the consumption of canned fish products did not pose any risk based on the EWI levels and provisional tolerable weekly intake (PTWI) limits. However, three tuna samples had target hazard quotient (THQ) levels above the threshold (>1). Arsenic levels were found to increase the carcinogenic risk for child consumers if they heavily consumed 18 canned fish products, including 15 tuna, 2 salmon, and 1 mackerel. The maximum allowable consumption rates (CRmm) for each canned fish product were calculated monthly. Consequently, the consumption of canned fish by children can pose health risks.
Reactivities of indoleamine 2,3-dioxygenases
Creators: name: Kuo, Hsin Hen
Publisher: name: University of British Columbia
Year: 2013

description: The heme enzyme indoleamine 2,3-dioxygenase (IDO1) catalyzes L-Trp oxidation in non-hepatic mammalian tissues by inserting both atoms of dioxygen into the indole ring to form N-formylkynurenine. In the present work, IDO1 was found to oxidize β-NADH under aerobic conditions in the absence of other reactants. This reaction led to formation of the reactive dioxygen-adduct of this enzyme and supported the oxidation of L-Trp to N-formylkynurenine. These processes were accelerated by hydrogen peroxide, and inhibited by either superoxide dismutase or catalase. In contrast, anaerobic reaction of IDO1 with β-NADH required an electron-transfer mediator. It is proposed that trace amounts of peroxide formed by reaction of dioxygen with β-NADH lead to one-electron oxidation of this substrate by IDO1, whose products reduce dioxygen to superoxide which in turn reacts with the enzyme to form the dioxygen-adduct. Regeneration of peroxide through auto-oxidation of the dioxygen-adduct of IDO1 results in auto-catalytic formation of this enzyme product in the presence of β-NADH. IDO1 was also found to catalyze the oxidation of indole by hydrogen peroxide, both of which were independently thought to be non-substrate, and non-oxygen-donor, respectively. This reaction resulted in O ₂-independent formation of monooxygenated indoles and was not inhibited by superoxide dismutase or hydroxyl radical scavengers. Consumption of indole and peroxide exhibited a near one-to-one correspondence and isotopic labeling experiments identified peroxide as the source of oxygen incorporated by indole oxidation products. It is proposed that indole oxidation was coupled to oxygen transfer from ferryl species of IDO1 formed by reaction with peroxide by means of a peroxygenase activity that is mechanistically analogous to the peroxide-shunt activation of cytochrome P450 enzymes. A bacterial expression system for a human isozyme of IDO1 (IDO2) was constructed. Despite similar electronic properties to IDO1, recombinant IDO2 was far less efficient at catalyzing L-Trp oxidation. The midpoint reduction potentials and auto-oxidation kinetics of IDO2 were comparable to those of IDO1, arguing against enzyme oxidation as a significant contributor of diminished enzyme activity. It is proposed that differences in L-Trp binding properties of the isozymes are mainly responsible for this catalytic disparity.

description: We consider spatially homogeneous Lifshitz black hole solutions in five dimensional higher derivative gravity theories, which can be possible near horizon geometries of some systems that are interesting in the framework of gauge/gravity duality. We show the solutions belonging to the nine Bianchi classes in the pure R^2 gravity. We find that these black holes have zero entropy at non-zero temperatures and this property is the same as the case of BTZ black holes in new massive gravity at the critical point. In the most general quadratic curvature gravity theories, we find new solutions in Bianchi Type I and Type IX cases.

description: Intestinal organoids represent a three-dimensional cell culture system mimicking the mammalian intestine. The application of single-cell ablation for defined wounding via a femtosecond laser system within the crypt base allowed us to study cell dynamics during epithelial restitution. Neighboring cells formed a contractile actin ring encircling the damaged cell, changed the cellular aspect ratio, and immediately closed the barrier. Using traction force microscopy, we observed major forces at the ablation site and additional forces on the crypt sides. Inhibitors of the actomyosin-based mobility of the cells led to the failure of restoring the barrier. Close to the ablation site, high-frequency calcium flickering and propagation of calcium waves occured that synchronized with the contraction of the epithelial layer. We observed an increased signal and nuclear translocation of YAP-1. In conclusion, our approach enabled, for the first time, to unveil the intricacies of epithelial restitution beyond in vivo models by employing precise laser-induced damage in colonoids.

description: We examine here the acceleration of particles and high energy collisions in the the Janis-Newman- Winicour (JNW) spacetime, which is an extension of the Schwarzschild geometry when a massless scalar field is included. We show that while the center of mass energy of collisions of particles near the event horizon of a blackhole is not significantly larger than the rest mass of the interacting particles, in an analogous situation, it could be arbitrarily large in the JNWspacetime near the naked singularity. The high energy collisions are seen to be generic in the presence of a photon sphere in the JNW spacetime, whereas an extreme fine-tuning of the angular momentum of the colliding particles is required when the photon sphere is absent. The center of mass energy of collision near the singularity grows slowly for small and extremely large deviations from the Schwarzschild blackhole, but for intermediate strengths of the scalar field it rises moderately fast. As a possible and potentially interesting application, we point out that the presence of such high energy collissions may help the blackhole configurations to be distinguished from a naked singularity.

description: Using first principles methods, we investigate topological phase transitions as a function of exchange field in a Bi(111) bilayer. Evaluation of the spin Chern number for different magnitudes of the exchange field reveals that when the time reversal symmetry is broken by a small exchange field, the system enters the time-reversal broken topological insulator phase, introduced by Yang {\it et al.} in Phys. Rev. Lett. 107, 066602 (2011). After a metallic phase in the intermediate region, the quantum anomalous Hall phase with non-zero Chern number emerges at a sufficiently large exchange field. We analyze the phase diagram from the viewpoint of the evolution of the electronic structure, edge states and transport properties, and demonstrate that different topological phases can be distinguished by the spin-polarization of the edge states as well as spin or charge transverse conductivity.

description: Ein Realsplitting wie bei Geschiedenen oder eine Individualbesteuerung mit übertragbarem Grundfreibetrag sind traditionelle Reformoptionen für das Ehegattensplitting. Ihr Nachteil ist, dass sie die Grenzbelastungen des Einkommens von zweitverdienenden PartnerInnen kaum reduzieren und somit die Erwerbsbeteiligung von verheirateten Frauen nur wenig fördern. Ein weiterer Reformvorschlag sind Zusatzfreibeträge für Ehepaare. Diese sind aber schwer verständlich und begünstigen Beidverdiener-Paare mit mittleren und höheren Einkommen zusätzlich. Ein alternativer Steuerabzugsbetrag für Ehepaare stößt in Deutschland auf rechtliche Vorbehalte. Ein guter Kompromiss zwischen den verschiedenen Reformanforderungen wäre ein Realsplitting für Ehepaare mit einem Übertragungsbetrag in Höhe des Grundfreibetrags. Dieser Vorschlag genügt den rechtlichen Anforderungen, ist leicht verständlich, vermeidet Belastungen in den unteren und mittleren Einkommensgruppen, fördert die Erwerbsbeteiligung von Zweitverdienenden und erzielt ein gewisses Steuermehraufkommen.

description: Central and spin-spin potentials for charmonium, constructed from Nambu-Bethe-Salpeter amplitudes in lattice simulations of full QCD, are matched with results from perturbative QCD at an appropriate distance scale. This matching is made possible by defining the perturbative potentials through Fourier transforms with a low-momentum cutoff. The central (spin-independent) potential is compared with potentials derived from an expansion in powers of the inverse quark mass. A well-controlled continuation of the charmonium spin-spin potential from lattice QCD to short distances is performed. The mass splittings of the charmonium singlet and triplet states below the open charm threshold, obtained from the matched spin-spin potential, are in good agreement with the experimental values.

Shaping the Brown Dwarf Desert: Predicting the Primordial Brown Dwarf Binary Distributions from Turbulent Fragmentation

description: The formation of brown dwarfs (BDs) poses a key challenge to star formation theory. The observed dearth of nearby ($\leq 5$ AU) brown dwarf companions to solar-mass stars, known as the brown dwarf desert, as well as the tendency for low-mass binary systems to be more tightly-bound than stellar binaries, have been cited as evidence for distinct formation mechanisms for brown dwarfs and stars. In this paper, we explore the implications of the minimal hypothesis that brown dwarfs in binary systems originate via the same fundamental fragmentation mechanism as stars, within isolated, turbulent giant molecular cloud cores. We demonstrate analytically that the scaling of specific angular momentum with turbulent core mass naturally gives rise to the brown dwarf desert, as well as wide brown-dwarf binary systems. Further, we show that the turbulent core fragmentation model also naturally predicts that very low-mass (VLM) binary and BD/BD systems are more tightly-bound than stellar systems. In addition, in order to capture the stochastic variation intrinsic to turbulence, we generate $10^4$ model turbulent cores with synthetic turbulent velocity fields to show that the turbulent fragmentation model accommodates a small fraction of binary brown dwarfs with wide separations, similar to observations. Indeed, the picture which emerges from the turbulent fragmentation model is that a single fragmentation mechanism may largely shape both stellar and brown dwarf binary distributions during formation.

description: We study the perturbative renormalizability of chiral two pion exchange in nucleon-nucleon scattering for p- and d-waves within the effective field theory approach. The one pion exchange potential is fully iterated at the leading order in the expansion, a choice generating a consistent and well-defined power counting that we explore in detail. The results show that perturbative chiral two pion exchange reproduces the data up to a center-of-mass momentum of k_cm ~300 MeV at NNLO and that the effective field theory expansion convergences up to k_cm ~ 350 MeV.

description: We report the interplay between charge-density-wave (CDW) and superconductivity of 1$T$-Fe$_{x}$Ta$_{1-x}$S$_{2}$ ($0\leq x \leq 0.05$) single crystals. The CDW order is gradually suppressed by Fe-doping, accompanied by the disappearance of pseudogap/Mott-gap as shown by the density functional theory (DFT) calculations. The superconducting state develops at low temperatures within the CDW state for the samples with the moderate doping levels. The superconductivity strongly depends on $x$ within a narrow range, and the maximum superconducting transition temperature is 2.8 K as $x=0.02$. We propose that the induced superconductivity and CDW phases are separated in real space. For high doping level ($x>0.04$), the Anderson localization (AL) state appears, resulting in a large increase of resistivity. We present a complete electronic phase diagram of 1$T$-Fe$_{x}$Ta$_{1-x}$S$_{2}$ system that shows a dome-like $T_{c}(x)$.

description: In the special case of a spherically symmetric solution of Einstein equations coupled to a scalar massless field, we examine the consequences on the exact solution imposed by a semiclassical treatment of gravitational interaction when the scalar field is quantized. In agreement with the work of Doplicher, Fredenhagen and Roberts (DFR), imposing the principle of gravitational stability against localization of events, we find that the region where an event is localized, or where initial conditions can be assigned, has a minimal extension, of the order of the Planck length. This conclusion, though limited to the case of spherical symmetry, is more general than that of DFR, since it does not require the use of the notion of energy through the Heisenberg Principle, nor of any approximation as the linearized Einstein equations. We shall then describe the influence of this minimal length scale in a cosmological model, namely a simple universe filled with radiation, which is effectively described by a conformally coupled scalar field in a conformal KMS state. Solving the backreaction, a power law inflation scenario appears close to the initial singularity. Furthermore, the initial singularity becomes light like and thus the standard horizon problem is avoided in this simple model. This indication goes in the same direction as those drawn at a heuristic level from a full use of the principle of gravitational stability against localization of events, which point to a background dependence of the effective Planck length, through which a-causal effects may be transmitted.

Jährlich wertet das DIW Berlin die Entwicklung des Heizenergiebedarfs in deutschen Wohngebäuden anhand eines umfangreichen Datenbestands aus. In diesem Jahr werden zudem die daraus entstehenden CO₂-Emissionen berechnet und mit der Zielsetzung für das Jahr 2030 im Bundes-Klimaschutzgesetz verglichen. Der temperaturbereinigte Heizenergiebedarf im Jahr 2019 ist im Vergleich zum Vorjahr leicht gesunken. Auch die CO2-Emissionen der untersuchten Zwei- und Mehrparteienhäuser gingen zurück – seit 2010 um rund 21 Prozent. Allerdings ist der Rückgang vor allem den wärmeren Wintern zu verdanken; temperaturbereinigt nahmen die CO₂-Emissionen in der letzten Dekade nur um rund drei Prozent ab. In den kommenden zehn Jahren müssen private Haushalte ihre Emissionen deutlich stärker reduzieren, um das Klimaziel für 2030 zu erreichen. Stärkere Anreize für energieeffiziente Gebäudesanierungen könnten die höhere Förderrate für energetische Sanierung und die geplante CO2-Bepreisung ab dem Jahr 2021 schaffen. Nur durch weitere umfangreiche Maßnahmen kann die Lücke zwischen prognostizierten und zulässigen Emissionsmengen geschlossen werden.

title: A Study of the Collection and Sharing of Student Data with Virginia Universities

Publisher: name: Old Dominion University Libraries
Year: 2023

description: Data collection is a vital component in any organization in regards to keeping track of user activity, gaining statistics and improving the user experience, and user identification. While the underlying basis of data collection is understandable, the use of this data has to be closely regulated and documented. In many cases, the VCDPA (Virginia Consumer Data Protection Act) outlines the guidelines for data use, data controller responsibilities, and limitations however nonprofit organizations are exempt from compliance. Colleges and universities, although still held to some degree of limitation, range in permissiveness with what data they choose to collect and retain but more importantly how and who they share their data with. This study implemented the use of open-coding techniques to look into seventeen different public and private universities in the state of Virginia. Their privacy policies were looked over and compared to the guidelines of the VCDPA to see if Universities were to follow the Data Protection Act, would they uphold the assessments and guidelines. Each of the seventeen universities collected different information and had different policies about who they shared their data too, if at all. A rudimentary scale was created to put each University in a placement. A One on the scale showed that the University was very conservative with their data collection and did not allow any distribution of the University's data to be shared or sold to third party companies. They followed the necessary laws from the government (i.e., turning over student documentation in the case of an investigation, etc) and reserved all other data for the University. A Five on the scale represented an extremely permissive policy that shared data with third-parties and that would violate the VCDPA guidelines if they were held against them. Finally, after all the information was gathered and organized, the question arose of Should nonprofit organizations be held to the same guidelines as for-profits and why? The findings draw attention to the gap in accountability between for-profit and nonprofit organizations, and highlight how some nonprofits have taken advantage of the deliberate inattention and freedoms given to them.

description: We present the first statistical study of X-ray cavities in distant clusters of galaxies (z > 0.3). With the aim of providing further insight into how AGN feedback operates at higher redshift, we have analysed the Chandra X-ray observations of the Massive Cluster Survey (MACS) and searched for surface-brightness depressions associated with the Brightest Cluster Galaxy (BCG). The MACS sample consists of the most X-ray luminous clusters within 0.3 < z < 0.7 (median L_(X,RASS) = 7*10^44 erg/s), and out of 76 clusters, we find 13 with "clear" cavities and 7 with "potential" cavities (detection rate ~25 per cent). Most of the clusters in which we find cavities have a short central cooling time below 3 - 5 Gyrs, consistent with the idea that cavities sit predominantly in cool core clusters. We also find no evidence for evolution in any of the cavity properties with redshift, up to z~0.6. The cavities of powerful outbursts are not larger (or smaller) at higher redshift, and are not able to rise to further (or lesser) distances from the nucleus. The energetics of these outbursts also remain the same. This suggests that extreme "radio mode" feedback (L_(mech) > 10^44 erg/s) starts to operate as early as 7 - 8 Gyrs after the Big Bang and shows no sign of evolution since then. In other words, AGNs lying at the centre of clusters are able to operate at early times with extreme mechanical powers, and have been operating in such a way for at least the past 5 Gyrs.

description: We present a theoretical and experimental study of spin precession in the presence of both a static and an orthogonal oscillating magnetic field, which is nonresonant, not harmonically related to the Larmor precession, and of arbitrary strength. Due to the intrinsic nonlinearity of the system, previous models that account only for the simple sinusoidal case cannot be applied. We suggest an alternative approach and develop a model that closely agrees with experimental data produced by an optical-pumping atomic magnetometer. We demonstrate that an appropriately designed nonharmonic field makes it possible to extract a linear response to a weak dc transverse field, despite the scalar nature of the magnetometer, which normally causes a much weaker, second-order response.

Mutation of Andreev into Majorana bound states in long NS and SNS junctions

description: We study one-dimensional topological SN and SNS long junctions obtained by placing a topological insulating nanowire in the proximity of either one or two SC finite-size leads. Using the Majorana Polarization order parameter (MP) introduced in Phys. Rev. Lett. 108, 096802 (2012)(arxiv:1109.5697) we find that the extended Andreev bound states (ABS) of the normal part of the wire acquire a finite MP: for a finite-size SN junction the ABS spectrum exhibits a zero-energy extended state which carries a full Majorana fermion, while the ABS of long SNS junctions with phase difference $π$ transform into two zero-energy states carrying two Majorana fermions with the same MP. Given their extended character inside the whole normal link, and not only close to an interface, these Majorana-Andreev states can be directly detected in tunneling spectroscopy experiments.

Universal dynamics on the way to thermalisation

description: It is demonstrated how a many-body system far from thermal equilibrium can exhibit universal dynamics in passing a non-thermal fixed point. As an example, the process of Bose-Einstein (BE) condensation of a dilute cold gas is considered. If the particle flux into the low-energy modes, induced, e.g., by a cooling quench, is sufficiently strong, the Bose gas develops a characteristic power-law single-particle spectrum $n(k)\sim k^{-5}$, and critical slowing down in time occurs. The fixed point is shown to be marked by the creation and dilution of tangled vortex lines. Alternatively, for a weak cooling quench and particle flux, the condensation process runs quasi adiabatically, passing by the fixed point in far distance, and signatures of critical scaling remain absent.

MAC protocol design and resource management for distributed cognitive radio networks
Creators: name: Jha, Satish Chandra
Publisher: name: University of British Columbia
Year: 2013

description: Cognitive radio (CR) has drawn extensive attention as a promising technique to enable dynamic spectrum allocation in wireless networks in order to increase spectrum utilization. Since coordination and communication over wireless medium is mainly performed at medium access control (MAC) layer, design of a smart MAC is vital for successful deployment of distributed CR network (DCRN). In this thesis, we first investigate research challenges specific to DCRN MAC design and present an overview of current state-of-the-art DCRN MAC protocols. We then propose a MAC protocol called OMC-MAC to address major research issues in DCRN. The distributed architecture and uncertainty in resource availability make QoS provisioning a challenging problem in such networks. Therefore, we incorporate a QoS support module in OMC-MAC in order to provide QoS guarantee to delay sensitive applications. We also investigate adaptive admission control mechanism to limit QoS users in DCRN. Next, we propose resource allocation schemes based on cross-layer interaction between MAC and network layers to minimize network wide resource wastage in multi-hop DCRN. In multi-hop DCRN, loss of a packet after traveling some hops results in wasting all resources allocated to it in previous hops. We propose schemes to allocate transmit power favoring packets which have traveled more hops before reaching resource allocating node. Similar resource allocation schemes are also investigated for multi-hop distributed orthogonal frequency division multiple access network. Finally, we explore research challenges and potential solution approaches in achieving virtualized future generation cellular networks. Network virtualization (NV) has been envisioned as a promising approach to reshape future generation wireless networks by enabling coexistence of several heterogeneous virtual networks to efficiently share the same physical resources and infrastructure. Successful implementation of NV in cellular systems largely depends on virtualization of their radio access part. Therefore, we investigate research issues in virtualizing radio access of cellular systems. We also discuss the potential of MAC mechanism and resource management developed in this thesis in enabling NV.

description: Let $A$ be an algebra over a commutative ring $k$. We compute the center of the category of $A$-bimodules. There are six isomorphic descriptions: the center equals the weak center, and can be described as categories of noncommutative descent data, comodules over the Sweedler canonical $A$-coring, Yetter-Drinfeld type modules or modules with a flat connection from noncommutative differential geometry. All six isomorphic categories are braided monoidal categories: in particular, the category of comodules over the Sweedler canonical $A$-coring $A \ot A$ is braided monoidal. We provide several applications: for instance, if $A$ is finitely generated projective over $k$ then the category of left End_k(A)$-modules is braided monoidal and we give an explicit description of the braiding in terms of the finite dual basis of $A$. As another application, new families of solutions for the quantum Yang-Baxter equation are constructed: they are canonical maps $Ω$ associated to any right comodule over the Sweedler canonical coring $A \ot A$ and satisfy the condition $Ω^3 = Ω$. Explicit examples are provided.

description: Die Wohnraumversorgung ist ein wichtiger Indikator für das Wohlbefinden innerhalb einer Gesellschaft. In der DDR versprach die sozialistische Wohnungspolitik den BürgerInnen niedrige Mieten und einen hohen Kündigungsschutz. Dafür war die durchschnittliche Wohnraumqualität gering und die Möglichkeiten, die eigene Wohnsituation an individuellen Bedürfnisse anzupassen, äußerst beschränkt. Mit der Wende fielen diese Restriktionen und der Wohnungsmarkt wurde liberalisiert. Für die Bevölkerung Ostdeutschlands brachte diese Anpassung an den westdeutschen Wohnungsmarkt Vor- und Nachteile mit sich. Einerseits steht den ostdeutschen MieterInnen heute mehr Pro-Kopf-Wohnfläche zur Verfügung und sie berichten eine höhere Zufriedenheit mit ihren Wohnungen. Andererseits ist der Wohnraum teurer geworden, wodurch auch die Mietbelastung deutlich gestiegen ist. Für Menschen mit niedrigen Einkommen ist dieser Anstieg ausgeprägter als für Menschen mit hohen Einkommen. Dennoch sollte dieser Befund nicht als Anlass für eine Verstärkung restriktiver Eingriffe in den Wohnungsmarkt dienen. Mit Blick auf die gestiegene Mietbelastung sollte eher auf eine gezielte finanzielle Unterstützung benachteiligter Haushalte und eine Verbesserung der Rahmenbedingungen für die Ausweitung des Angebots an bezahlbarem Wohnraum gesetzt werden.
