description: We investigate the symmetry constraints on the bispectrum, i.e. the three-point correlation function of primordial density fluctuations, in slow-roll inflation. It follows from the defining property of slow-roll inflation that primordial correlation functions inherit most of their structure from weakly broken de Sitter symmetries. Using holographic techniques borrowed from the AdS/CFT correspondence, the symmetry constraints on the bispectrum can be mapped to a set of stress-tensor Ward identities in a weakly broken 2+1-dimensional Euclidean CFT. We construct the consistency condition from these Ward identities using conformal perturbation theory. This requires a second order Ward identity and the use of the evolution equation. Our result also illustrates a subtle difference between conformal perturbation theory and the slow roll expansion.

description: With anomalies found in cosmic ray observations and unsolved questions of the Standard Model of particle physics like the discrepancy in the muon's anomalous magnetic moment, the idea of an U(1) extension of the Standard Model arose. This extension allows for the interaction of Dark Matter by exchange of a photon-like massive force carrier $A'$ not included in the Standard Model. We discuss the possibility to constrain the dark photon parameter space by using data taken from rare kaon decays. Therefore we analyze the decay $K\rightarrow μνA'$ as a signal process and calculate the expected Standard Model background. Using these results we calculate new limits on the $A'$ parameter space, providing motivations for new rare kaon decay experiments to extend the existing $A'$ bounds.

description: We present the results of 12CO J = 1-0 line observations of eleven Galactic supernova remnants (SNRs) obtained using the Seoul Radio Astronomy Observatory (SRAO) 6-m radio telescope. The observation was made as a part of the SRAO CO survey of SNRs between l = 70 and 190 deg, which is intended to identify SNRs interacting with molecular clouds. The mapping areas for the individual SNRs are determined to cover their full extent in the radio continuum. We used halfbeam grid spacing (60") for 9 SNRs and full-beam grid spacing (120") for the rest. We detected CO emission towards most of the remnants. In six SNRs, molecular clouds showed a good spatial relation with their radio morphology, although no direct evidence for the interaction was detected. Two SNRs are particularly interesting: G85.4+0.7, where there is a filamentary molecular cloud along the radio shell, and 3C434.1, where a large molecular cloud appears to block the western half of the remnant. We briefly summarize the results obtained for individual SNRs.

Retarded Green's Function Of A Vainshtein System And Galileon Waves

description: Motivated by the desire to test modified gravity theories exhibiting the Vainshtein mechanism, we solve in various physically relevant limits, the retarded Galileon Green's function (for the cubic theory) about a background sourced by a massive spherically symmetric static body. The static limit of our result will aid us, in a forthcoming paper, in understanding the impact of Galileon fields on the problem of motion in the solar system. In this paper, we employ this retarded Green's function to investigate the emission of Galileon radiation generated by the motion of matter lying deep within the Vainshtein radius r_v of the central object: acoustic waves vibrating on its surface, and the motion of compact bodies gravitationally bound to it. If λis the typical wavelength of the emitted radiation, and r_0 is the typical distance of the source from the central mass, with r_0 << r_v, then, compared to its non-interacting massless scalar counterpart, we find that the Galileon radiation rate is suppressed by the ratio (r_v/λ)^{-3/2} at the monopole and dipole orders at high frequencies r_v/λ>> 1. However, at high enough multipole order, the radiation rate is enhanced by powers of r_v/r_0. At low frequencies r_v/λ<< 1, and when the motion is non-relativistic, Galileon waves yield a comparable rate for the monopole and dipole terms, and are amplified by powers of the ratio r_v/r_0 for the higher multipoles.

Accretion onto Black Holes from Large Scales Regulated by Radiative Feedback. III. Enhanced Luminosity of Intermediate Mass Black Holes Moving at Supersonic Speeds

description: In this third paper of a series, we study the growth and luminosity of black holes (BHs) in motion with respect to their surrounding medium. We run a large set of two-dimensional (2D) axis-symmetric simulations to explore a large parameter space of initial conditions and formulate an analytical model for the accretion. Contrary to the case without radiation feedback, the accretion rate increases with increasing BH velocity $\vbh$ reaching a maximum value at $\vbh=2c_{\rm s,in}\sim 50$ km/s, where $c_{\rm s,in}$ is the sound speed inside the "cometary-shaped" \hii region around the BH, before decreasing as $\vbh^{-3}$ when the I-front becomes {\it R}-type (rarefied) and the accretion rate approaches the classical Bondi-Hoyle-Lyttleton solution. The increase of the accretion rate with $\vbh$ is produced by the formation of a {\it D}-type (dense) ionization front (I-front) preceded by a standing bow-shock that reduces the downstream gas velocity to transonic values. There is a range of densities and velocities where the dense shell is unstable producing periodic accretion rate peaks which can significantly increase the detectability of intermediate mass BHs. We find that the mean accretion rate for a moving BH is larger than that of a stationary BH of the same mass if the medium temperature is $T_\infty<10^4$ K. This result could be important for the growth of seed BHs in the multi-phase medium of the first galaxies and for building and early X-ray background that may affect the formation of the first galaxies and the reionization process.

description: We study the distribution of maxima (Extreme Value Statistics) for sequences of observables computed along orbits generated by random transformations. The underlying, deterministic, dynamical system can be regular or chaotic. In the former case, we will show that by perturbing rational or irrational rotations with additive noise, an extreme value law appears, regardless of the intensity of the noise, while unperturbed rotations do not admit such limiting distributions. In the case of deterministic chaotic dynamics, we will consider observables specially designed to study the recurrence properties in the neighbourhood of periodic points. Hence, the exponential limiting law for the distribution of maxima is modified by the presence of the extremal index, a positive parameter not larger than one, whose inverse gives the average size of the clusters of extreme events. The theory predicts that such a parameter is unitary when the system is perturbed randomly. We perform sophisticated numerical tests to assess how strong is the impact of noise level, when finite time series are considered. We find agreement with the asymptotic theoretical results but also non-trivial behaviour in the finite range. In particular our results suggest that in many applications where finite datasets can be produced or analysed one must be careful in assuming that the smoothing nature of noise prevails over the underlying deterministic dynamics.

Gender and social sciences involvement in technology development projects in energy (TR)
Creators: name: Derin Gure, Pinar
Publisher: name: Zenodo
Year: 2023

description: Even with the most sophisticated and advanced technologies, technological innovations in energy can fail to deliver results if society would not accept them. Under specific circumstances, changes in energy technologies might have certain economic and social benefits as well as costs to society. By detecting these, the socio-economic research on energy can put light on proper energy transition strategies for society, the industry, and policymakers. In the last years, European Commission, as well as TÜBITAK, started to emphasize the role of Social Sciences and Humanities (SSH) involvement in Technological Projects. This talk will aim to put the challenges, barriers as well as benefits (the low-hanging fruits) for the participation of SSH research on technological innovations. This talk will also aim to discuss the role of gender in technology development projects. Horizon Europe made it mandatory for the institutions to have a gender equality plan (GEP) before applying for Project funding. In addition to this, it became compulsory to include the gender dimension in the R&I content under Horizon Europe applications. The range of GEP and probable gender dimensions in energy R&I and its potential impact on Turkish research institutions will be discussed.

description: Convenience and safeguarding our home appliances have become an important issue when dealing with an advancement and growth of an economy. This research focuses on the design and construction of a Dual Sensor heat-monitoring system. The circuit works by monitoring temperature from an external input and comparing the temperature level with that of a preset temperature value. The power output of the circuit is cut off or switched OFF or an alarm is triggered ON if the temperature of the external input is equal to or, greater than the preset temperature value. The methodology involves the application of linear precision temperature sensors i.e., they generate a voltage that is directly proportional to the temperature. Basically the system is constructed using temperature sensors and comparators. The system is powered using a 12V power supply. The results of the tests showed that the power output of the circuit is switched OFF hence switching OFF the heating device or an alarm is triggered ON when the device exceeded a preset temperature level. The general operation of the system and performance is dependent on the temperature difference between the preset temperature value and external temperature intended to be monitored. The overall system was tested and found perfectly functional.

description: A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb-1 of sqrt(s) = 7 TeV proton-proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results.

description: The large N limit has been successfully applied to QCD, leading to qualitatively correct results even for N=3. In this work, we propose to treat the number N=3 of Standard Model generations as a large number. Specifically, we apply this idea to the neutrino anarchy scenario and study neutrino physics using Random Matrix Theory, finding new results in both areas. For neutrino physics, we obtain predictions for the masses and mixing angles as a function of the generation number N. The Seesaw mechanism produces a hierarchy of order 1/N^3 between the lightest and heaviest neutrino, and a theta(13) mixing angle of order 1/N, in parametric agreement with experimental data when N goes to 3. For Random Matrix Theory, this motivates the introduction of a new type of ensemble of random matrices, the "Seesaw ensemble." Basic properties of such matrices are studied, including the eigenvalue density and the interpretation as a Coulomb gas system. Besides its mathematical interest, the Seesaw ensemble may be useful in random systems where two hierarchical scales exist.

description: Composite of dextrose-derived oxygen-rich carbon spheres and graphene oxide, synthesised using a cost-effective and easy hydrothermal process, was used as an active material in two of the trending and promising energy storage devices. The surface morphology and properties of the composite were studied using scanning electron microscope, X-ray diffractometer, energy dispersive X-ray analysis, elemental mapping and Raman spectra. To analyse the electrochemical behaviour of the material, several electrochemical techniques such as cyclic voltammetry (CV), chronopotentiometry, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarisation study were used. The reversibility of Fe2+/Fe3+ redox species and resistance offered by electrolyte towards the modified electrode were studied using CV, EIS and Tafel studies. Further evaluation of efficacy of the active material towards the iron redox flow battery (IRFB) of 132 cm2 area was analysed by performing charge discharge studies at varied current densities. Substantial increase in the electrochemical performance of the IRFB with a coulombic efficiency (CE) 93% along with the good life cycle stability up to 25 cycles was observed. The composite was also used as a superior electrode material for supercapacitor application resulting in significant enhancement in the electrochemical performance with specific capacitance of 610 F g−1 and CE of 83% with 93% retention up to 1600 cycles.

description: Euclidean special geometry has recently been investigated in the context of Euclidean supersymmetric theories with vector multiplets. In the rigid case, the scalar manifold is described by affine special para-Kahler geometry while the target geometries of Euclidean vector multiplets coupled to supergravity are given by projective special para-Kahler manifolds. In this letter, we derive the Killing spinor equations of Euclidean N=2 supergravity theories coupled to vector multiplets. These equations provide the starting point for finding general supersymmetric instanton solutions.

description: In this work, BiPO4 (BPO)-based photocatalyst was successfully synthesized by a conventional hydrothermal strategy using bismuth nitrate pentahydrate (Bi(NO3)3·5H2O) and 1-ethyl-3-methylimidazolium dihydro phosphate ([EMIm]H2PO4). [EMIm]H2PO4 can serve as a phosphorus source and surfactant. Photocatalytic activities of the photocatalysts prepared were evaluated by the destruction of rhodamine B (RhB) and tetracycline (TC) under UV light irradiation, respectively. The results reveal that the sample (IL-BPO) synthesized with the assistance of ionic liquid exhibits enhanced photocatalytic activity in comparison with the reference BiPO4. The significantly improved photocatalytic activity of IL-BPO can be mainly attributed to the boosted separation of photoinduced electron-hole pairs (e−/h+) and richer oxygen vacancies (OVs).

The random phase approximation (RPA) is an efficient way to generate strength distributions. In order to better understand both theoretical systematics and uncertainties, we compare the Gamow-Teller strength distributions for a suite of nuclides and for a suite of interactions, including semi-realistic interactions in the $1p$-$0f$ space with the RPA and a separable multi-shell interaction in the quasi-particle RPA. We also compare with experimental results for GT$_-$ on ${54}$Fe.

description: We consider quiver theories in four dimensions with a large ultra-violet cutoff. These theories require that an ordered set of vacuum expectation values for the link fields develops dynamically and can be obtained from the coarse deconstruction of extra-dimensional theories in an AdS background. These full-hierarchy quiver theories form a large class which include AdS$_5$ models as a limit, but which have a distinctive phenomenology. As an example, in this paper we show that fermions can be introduced in a way that can at the same time generate the fermion mass hierarchy and have flavor violation consistent with experimental bounds, when the mass scale of the color-octect gauge excitation is above $3 {\rm TeV}$. We also show that electroweak precision constraints are satisfied by this mass scale, without the need to extend the gauge sector to protect against custodial violation.

description: Well-known examples, e.g. Paul McCartney who composed “Yesterday” because of a dream, have shown how dreams can inspire creativity. In a sample population of 2492 participants who completed an online questionnaire the goal of this study was to examine the frequency of dreams which stimulate creative ideas and help solving problems. Participants had on average both creative ideas and problem solving help by dreams once every other month. Factors such as gender, age, attitude towards dreams and personality traits influenced the frequency. Although all personality traits showed an impact on the frequency, Openness to Experience and Neuroticism had the strongest influence. Agreeableness and Conscientiousness showed negative correlations only with the creative ideas by dreams item. Persons with higher scores of Openness to Experience and Neuroticism were more often influenced by their dreams. Further research could have a look at persons working in creative fields and possible results of creative and problem solving dreams, e.g., new music, advertising slogans, website designs, and poems.

Further evaluation of efficacy of the active material towards the iron redox flow battery (IRFB) of 132 cm2 area was analyzed by performing charge discharge studies at varied current densities. Substantial increase in the electrochemical performance of the IRFB with a coulombic efficiency 93% along with the good life cycle stability up to 25 cycles was observed. The composite was also used as an superior electrode material for supercapacitor application resulting in significant enhancement in the electrochemical performance with specific capacitance of 610 Fg-1 and coulombic efficiency of 83% with 93% retention up to 1600 cycles.

description: Systems biology approaches combining theoretical modeling with experiments have been singularly successful in uncovering novel features of cellular phenomena. One such feature is that of binary gene expression in which the expression level is either low or high, i.e., digital in nature. This gives rise to two distinct subpopulations in a population of genetically identical cells. The fraction of cells in the high expression state is raised as the strength of the inducing signal is increased indicating that the response is not graded. In this review, we discuss the possible origins of binary gene expression with emphasis on three principal mechanisms: purely stochastic, positive feedback-based and emergent bistability. In the latter case, two stable expression states are obtained due to an autoregulatory positive feedback loop in protein synthesis along with cell growth retardation by the proteins synthesized. The theoretical foundations of the observed phenomena are described in each case.

description: We report a method of fabricating self-aligned, top-gated graphene field-effect transistors (GFETs) employing polyethyleneimine spin-on-doped source/drain access regions, resulting in a 2X reduction of access resistance and a 2.5X improvement in device electrical characteristics, over undoped devices. The GFETs on Si/SiO$_2$ substrates have high carrier mobilities of up to 6,300 cm$^2$/Vs. Self-aligned spin-on-doping is applicable to GFETs on arbitrary substrates, as demonstrated by a 3X enhancement in performance for GFETs on insulating quartz substrates, which are better suited for radio frequency applications.

description: We prove Suslin's local-global principle for principal congruence subgroups of Chevalley groups. Let $G$ be a Chevalley--Demazure group scheme with a root system $Φ\ne A_1$ and $E$ its elementary subgroup. Let $R$ be a ring and $I$ an ideal of $R$. Assume additionally that $R$ has no residue fields of 2 elements if $Φ=C_2$ or $G_2$. Theorem. Let $g\in G(R[X],XR[X])$. Suppose that for every maximal ideal $\m$ of $R$ the image of $g$ under the localization homomorphism at $\m$ belongs to $E(R_\m[X],IR_\m[X])$. Then, $g\in E(R[X],IR[X])$. The theorem is a common generalization of the result of E.Abe for the absolute case ($I=R$) and H.Apte--P.Chattopadhyay--R.Rao for classical groups. It is worth mentioning that for the absolute case the local-global principle was obtained by V.Petrov and A.Stavrova in more general settings of isotropic reductive groups.

description: Motivated by analogue models of classical and quantum field theory in curved spacetimes and their recent experimental realizations, we consider wave scattering processes of dispersive fields exhibiting two extra degrees of freedom. In particular, we investigate how standard superradiant scattering processes are affected by subluminal or superluminal modifications of the dispersion relation. We analyze simple 1-dimensional toy-models based on fourth-order corrections to the standard second order wave equation and show that low-frequency waves impinging on generic scattering potentials can be amplified during the process. In specific cases, by assuming a simple step potential, we determine quantitatively the deviations in the amplification spectrum that arise due to dispersion, and demonstrate that the amplification can be further enhanced due to the presence of extra degrees of freedom. We also consider dispersive scattering processes in which the medium where the scattering takes place is moving with respect to the observer and show that superradiance can also be manifest in such situations.

Year: 2023

description: The European Commission has supported a better integration of non-economic energy-Social Sciences and Humanities into the energy research and policy process in the last years. It is considered crucial that SSH topics and approaches are included in European funding strategies, and that the SSH community is included in selection processes. Energy transitions are not only technological and ecological challenges but also political and social ones. We need to draw on many kinds of knowledge – including evidence from the Social Sciences and Humanities (SSH). In this presentation, we explore the challenges in the integration of SSH approaches and methods in the energy domain and discuss several topics where energy SSH have produced more valuable results

description: To integrate 5G mobile radio into Time-Sensitive Networking (TSN), the 3rd Generation Partnership Project (3GPP) specified the model of a virtual 5G-TSN bridge. This contains TSN translators which map principles such as time synchronization and Quality of Service (QoS) mechanisms from TSN to 5G. However, practical implementations with fine-granular QoS differentiation are not available yet. Therefore, in this paper, we examine the transmission delays of frames of the eight TSN traffic classes by simulating different scenarios while varying the QoS parameters priority, periodicity, and frame length. Our research contribution includes indications for the 5G bridge delay and Packet Delay Budget (PDB) depending on the traffic characteristics in a converged wired and wireless 5G-TSN network. This serves as a basis for the development of TSN translators and finally of a joint QoS model.

description: Nicht zuletzt mit aktuellen „vPLC“-Offerten gewinnt der Einsatz von IT-Technologien wie Docker und Kubernetes zum Virtualisieren und Orchestrieren der Industrieautomation an Fahrt. Die IT verfügt über bewährte Blaupausen zum Strukturieren von Applikationen und deren virtueller Kommunikation auch in größeren Container-Systemen. In der Praxis stoßen Anwender, Entwickler, Experten und Forschende aus Automatisierung und Industrie-Kommunikation immer wieder auf überraschendes oder unerwünschtes Systemverhalten. Umfangreiche Online-Dokumentation und heutige Kommandozeilen-Werkzeuge sind dabei sowohl Hilfe als auch Hürde, um die virtuellen Systeme und Netzwerke zu durchdringen und diagnostizieren: warum kommen keine Telegramme in der Anlage an, warum gehen keine Daten die die Cloud, …? In der eigenen mehrjährigen Praxis als „containerisierter Systemarchitekt“ u.a. bei der Siemens „Industrial Edge“ ist deshalb das anfangs interne Projekt „Edgeshark“ entstanden und stetig weiterentwickelt worden. Siemens steuert nun das Projekt (MIT-Lizenz) zur Github OpenSource Community bei. In diesem Beitrag steht jedoch nicht das Werkzeug im alleinigen Mittelpunkt, sondern es soll vielmehr wie ein guter Ausbilder Interessierten einen einfachen Zugang zu verschiedenen Elementen der virtuellen (und auch realen) Kommunikation in Containersystemen ermöglichen. Der Zugang kann explorativ über eine Weboberfläche erfolgen, genauso kann Edgeshark auch per REST API einfach in neuen Aufgaben eingebunden werden. Weiterhin existiert eine Integration samt Live-Übertragung zum OpenSource-Werkzeug Wireshark.

description: LoRaWAN Range Extension for Environments with High Attenuation Martin Böhm, Olaf Gebauer, Diederich Wermser Research Group Communication Systems Ostfalia University Salzdahlumer Str. 46/48 38302 Wolfenbüttel, Germany {ma.boehm | ola.gebauer | d.wermser}@ostfalia.de Abstract: The deployment of widespread LPWAN sensor networks, such as LoRaWAN, in high attenuation environments like forests and mines, faces a significant challenge due to the considerable reduction in communication range. LoRaWAN gateways are typically deployed to expand network coverage. These gateways require internet connectivity, often realized using cellular networks. However, in such deployment areas, cellular coverage may be limited or entirely unavailable. The use of LoRaWAN range extenders to extend coverage is inevitable. However, current LoRaWAN range extenders provide only limited coverage extension as they lack multi-hop support, necessitating the presence of online gateways. In this work, a new approach for LoRaWAN range extenders, named the LoRaWAN GW2ED Range Extender, is presented. Briefly explained, the new solution combines a LoRaWAN gateway, a local middleware, and an LoRaWAN end-device without the need for internet access by the range extender. The new approach is compared to other range extender solutions. The implementation of the concept is illustrated by architecture and sequence diagrams. In field tests within a dense forest, each PoC LoRaWAN GW2ED Range Extender extended the LoRaWAN range by an additional kilometer. This new approach is fully compatible with the LoRaWAN specifications as well as with LoRaWAN Commercial Off-The-Shelf (COTS) end-devices.
