Modern distribution system analysis is informed by growing amounts of data, and much of this data is either directly or indirectly derived from measurements taken from the grid edge. As the dynamics of the distribution grid become more important to the system as a whole due to large amounts of DERs and the potential for operation of the whole grid at much lower levels of inertia, the dynamics of devices and the measurements themselves taken within the distribution system are becoming more important if not critical. This panel will explore areas of research related to sensor and measurement dynamics impacting distribution grid stability, state estimation and power quality.

The proliferation of climate change makes extreme weather events increasingly more common and more severe. Electric utilities around the globe strive to maintain continuity of service to all customers and to promptly restore any component that has suffered an outage. The issues arising due to power outages most times propagate to non-grid factors, including the health of the local community, access to critical facilities and other economic, social and community aspects.  With this motivation, this panel will include talks from experts to provide insight on current and emerging measures to increase resilience to major events, such as hurricanes, floods, and wildfires. The panel will convey the experience of these utilities when assessing damage, calculating the societal impact of the energy not served, and the incorporation of improved design, non-wires alternative, and enhanced weather forecast in their planning.

The effect of a dopamine antagonist and an agonist on rats’ perception of reward quantity : an examination of the anhedonia hypothesis
Creators: name: Martin-Iverson, Mathew Thomas
Publisher: name: University of British Columbia
Year: 2010

description: A procedure was developed to determine the effect of a dopamine (DA) antagonist (haloperidol) and a DA agonist (d-amphetamine) on rats' perceptions of the hedonic value of food. Eighteen rats were trained to discriminate between two quantities of sweet food pellets (1 and 4), in a forced-choice two-lever successive discrimination procedure. To control for non-specific perceptual effects of the treatments, the rats were also trained to discriminate between 1 and 4 tones. It was established that rats attended to the value of food, as well as the proportional differences in quantity, when discriminating food quantities. This was accomplished by altering the value of the food in two ways. Firstly, "hunger" was altered by changing the degree of food deprivation during testing. Secondly, unsweetened food pellets were introduced as probe cues. These two methods of altering the value of food pellets were utilized while quantity generalization gradients were determined, by presenting animals with 1,2, 3 and 4 numbers of stimuli as probe cues. Two measures were derived from these generalization gradients: the point of subjective equality (PSE), which is the calculated number of stimuli that would maintain responses equally distributed between the two levers, and the slope of the gradient. The PSE primarily reflects perceptual processes, while the slopes of the gradients provide an index of performance impairment. It was observed that decreasing the value of food by either decreasing food deprivation or reducing the sweetness of the food pellets resulted in the rats perceiving a given quantity of food as larger than before these treatments (decreased the food PSE). Neither altering food deprivation nor introducing novel tone probes had an effect on the numerical attributes of tones, as reflected by the tone PSE. Haloperidol (0.030, 0.50 and 0.083 mg/kg, i.p.) produced a statistically significant, but slight dose-dependent performance deficit, as reflected by the slope of the generalization gradients. It did not affect the perception of food pellet quantities at any dose, as reflected by the food PSE. Haloperidol decreased the number of tones a given quantity was perceived as by rats (increased the tone PSE). Amphetamine (0.25, 0.50 and 1.0 mg/kg, i.p.) decreased the perception of a given quantity of food (increased the food PSE) in a dose-dependent manner, without a significant effect on performance. Thus, amphetamine enhanced the hedonic value of food. Amphetamine also increased rats' perceptions of a given number of tones (decreased the tone PSE). It therefore appears that while d-amphetamine can enhance the perceived hedonic value of food, haloperidol has no effect on rats' perceptions of the hedonic value of food. Furthermore, evidence that DA systems are involved in the mechanism of an "internal clock" or "counter" was obtained.

description: For the first time, Gallium Nitride(GaN)-based Gunn diodes with side-contact and fieldplate technologies were fabricated and measured with reliable characteristics. A high negative differential resistance (NDR) region was characterised for the GaN Gunn effect using side-contact technology. The I-V measurement of the THz diode showed the ohmic and the Gunn effect region with high forward current of 0.65 A and high current drop of approximately 100 mA for a small ring diode width wd of 1.5µm with 600 nm effective diode height hd at a small threshold voltage of 8.5 V. This THz diode worked stable due to good passivation as protection from electro-migration and ionisation between the electrodes as well as a better heat sink to the GaN substrate and large side-contacts. The diodes can provide for this thickness a fundamental frequency in the range of 0.3 - 0.4 THz with reliable characteristics.
title: Investigation of collectivity in the neutron-rich 142Xe
Creators: name: Henrich, Corinna

description: The neutron-rich 142Xe lies north-east of the doubly-magic 132Sn, in a region that is not only describable by nuclear theory with single-particle and mean-field approaches, but also became accessible in experiments in recent times. Since the astrophysical r process passes through the area, understanding the structure of nuclei therein may provide insight into the A=130 peak in the solar-element abundances. Furthermore, 144Ba, a nucleus that exhibits strong octupole collectivity, lies in the immediate proximity just two protons above 142Xe. In order to gain understanding on the evolution of quadrupole and octupole collectivity in this region, a Coulomb excitation experiment was carried out using the MINIBALL and C-REX setup at the HIE-ISOLDE facility, CERN. Several reduced transition strengths of low-lying transitions along with the spectroscopic quadrupole moments of the respective states could be determined. Additionally, new low-spin low-energy states, interpreted as part of a gamma band, demonstrated for the first time in this isotope, could be identified, and the location of the 3- state supported. The results are compared to SCCM and LSSM calculations.

Our approach, which is based on time-dependent current-density-functional theory, is applicable well beyond the linear-response regime and produces both spin-charge separation and spin-drag-induced broadening of the spin packets.

description: We investigate the total kinetic powers (L_j) and ages (t_age) of powerful jets in FR II radio galaxies by comparison of the dynamical model of expanding cocoons with observations. We select four FR II radio sources (Cygnus A, 3C 223, 3C 284, and 3C 219), for which the mass-density profiles of intracluster medium (ICM) are known in the literature. It is found that large fractions > 0.02 - 0.7 of the Eddington luminosity (L_Edd) are carried away as a kinetic power of jet. The upper limit of estimated 2 L_j / L_Edd are larger than unity (< 10) for some sources, suggesting a possibility of super-Eddington mass accretions. As a consequence of the large powers, we also find that the total energy stored in the cocoon (E_c) exceeds the energy derived from the minimum energy condition for the energy of radiating non-thermal electrons and magnetic fields (E_min): 4< E_c /E_min <310. This implies that most of the energy in cocoon is carried by invisible components such as thermal leptons (electron and positron) and/or protons.

description: In this work, hybridization of nonmetal nitrogen-doped carbon dots (NCQDs) with ZnO nanorods (NRs) is utilized towards better photocatalytic degradation of rhodamine B under ultraviolet (UV) irradiation. The structural characterization is confirmed by XRD, XPS, FTIR and HRTEM measurements, while, optical properties have been investigated using UV-visible absorbance spectroscopy and photoluminescence study. The dye degradation using ZnO NR is recorded as ~69%, while the performance of ZnO/NCQD climbs up to ~90%, after nine minutes of UV irradiation. Furthermore, the reusability test suggests better stability of ZnO/NCQD than bare ZnO under photocorrosion. The cyclic voltammetry study confirms that the photoinduced electron-hole pairs originate from the heterojunction established between the interfaces of NCQD and ZnO. An insight on the photocatalytic excellence of ZnO/NCQD system is drawn from the density functional theory study. This indicates that appropriate band alignment of the heterostructure constituents is the key factor in this experimental attempt towards environment remedy.

description: [Abridged] Most exoplanets detected so far are close-in planets, which are likely to be affected by tidal dissipation in their host star. To get a complete picture of the evolution of star-planet systems one needs to consider the impact of tides within both stellar radiative and convective zones. We aim to provide a general formalism to assess tidal dissipation in stellar radiative zones for all spectral types, allowing for the study of the dynamics of a given system throughout stellar evolution. We investigate the influence of stellar structure and evolution on tidal dissipation in the radiative core of low-mass stars. From the study of adiabatic oscillations throughout the star, we compute the energy flux transported by progressive internal gravity waves and the induced tidal torque. We then study the influence of stellar structure and evolution on tidal dissipation of solar-type stars from the pre-main sequence (PMS) to the red giant branch (RGB). For a given star-planet system, tidal dissipation reaches a maximum value on the pre-main sequence for all stellar masses. On the main sequence (MS), it decreases to become almost constant. The dissipation is then several orders of magnitude smaller for F-type stars than for G and K-type stars. During the Sub-Giant phase and the RGB, tidal dissipation increases by several orders of magnitude, along with the expansion of the stellar envelope. We show that the dissipation of the dynamical tide in the convective zone dominates the evolution of the system during most of the PMS and the beginning of the main sequence. Tidal dissipation in the radiative zone then becomes the strongest contribution during the Sub-Giant phase and the RGB. We also find that the dissipation of a metal-poor star is stronger than the dissipation of a metal-rich star during the PMS, the Sub-Giant phase and the RGB.

description: We consider a situation where an $N$-level system (NLS) is coupled to a heat bath without being necessarily thermalized. For this situation we derive general Jarzinski-type equations and conclude that heat and entropy is flowing from the hot bath to the cold NLS and, vice versa, from the hot NLS to the cold bath. The Clausius relation between increase of entropy and transfer of heat divided by a suitable temperature assumes the form of two inequalities which have already been considered in the literature. Our approach is illustrated by an analytical example.

description: The electron doping of undoped high-$T_c$ cuprates via the transfer of charge from manganites (or other oxides) using heterostructure geometries is here theoretically discussed. This possibility is mainly addressed via a detailed analysis of photoemission and diffusion voltage experiments, which locate the Fermi level of manganites above the bottom of the upper Hubbard band of some cuprate parent compounds. A diagram with the relative location of Fermi levels and gaps for several oxides is presented. The procedure discussed here is generic, allowing for the qualitative prediction of the charge flow direction at several oxide interfaces. The addition of electrons to antiferromagnetic Cu oxides may lead to a superconducting state at the interface with minimal quenched disorder. Model calculations using static and dynamical mean-field theory, supplemented by a Poisson equation formalism to address charge redistribution at the interface, support this view. The magnetic state of the manganites could be antiferromagnetic or ferromagnetic. The former is better to induce superconductivity than the latter, since the spin-polarized charge transfer will be detrimental to singlet superconductivity. It is concluded that in spite of the robust Hubbard gaps, the electron doping of undoped cuprates at interfaces appears possible, and its realization may open an exciting area of research in oxide heterostructures.

description: We consider the allocation of $m$ balls into $n$ bins with incomplete information. In the classical Two-Choice process a ball first queries the load of two randomly chosen bins and is then placed in the least loaded bin. In our setting, each ball also samples two random bins but can only estimate a bin's load by sending binary queries of the form "Is the load at least the median?" or "Is the load at least 100?". For the lightly loaded case $m=O(n)$, Feldheim and Gurel-Gurevich (2021) showed that with one query it is possible to achieve a maximum load of $O(\sqrt{\log n/\log \log n})$, and posed the question whether a maximum load of $m/n+O(\sqrt{\log n/\log \log n})$ is possible for any $m = Ω(n)$. In this work, we resolve this open problem by proving a lower bound of $m/n+Ω( \sqrt{\log n})$ for a fixed $m=Θ(n \sqrt{\log n})$, and a lower bound of $m/n+Ω(\log n/\log \log n)$ for some $m$ depending on the used strategy. We complement this negative result by proving a positive result for multiple queries. In particular, we show that with only two binary queries per chosen bin, there is an oblivious strategy which ensures a maximum load of $m/n+O(\sqrt{\log n})$ for any $m \geq 1$. Further, for any number of $k = O(\log \log n)$ binary queries, the upper bound on the maximum load improves to $m/n + O(k(\log n)^{1/k})$ for any $m \geq 1$. Further, this result for $k$ queries implies (i) new bounds for the $(1+β)$-process introduced by Peres et al (2015), (ii) new bounds for the graphical balanced allocation process on dense expander graphs, and (iii) the bound of $m/n+O(\log \log n)$ on the maximum load achieved by the Two-Choice process, including the heavily loaded case $m=Ω(n)$ derived by Berenbrink et al. (2006). One novel aspect of our proofs is the use of multiple super-exponential potential functions, which might be of use in future work.

Publisher: name: IEEE
Year: 2022

More and more inverter-based resources (IBRs) such as wind and solar generation, are integrated into power grids. IBRs pose many operation challenges including intermittence and low inertia resulting in large frequency variations, and low fault currents causing protection malfunction. In addition, unprecedent dynamic phenomena were observed in the real-world, e.g., large-scale solar PV tripping in California after transmission outage, low-frequency oscillations observed in both Texas and Australia after transmission outages due to IBRs with weak grid interconnections, to name a few. Accurate and computationally efficient dynamic stability assessment (DSA) for IBR-dominated power systems is an urgent need, and IBRs being “black-boxes” to grid operators seems to be the biggest hurdle. This panel session brings a group of government leaders, industry experts, inverter manufacturers, and academia researchers together to discuss the challenges for DSA, propose mitigation strategies, and reshape DSA for the changing grid. Specifically, industry experts will describe success stories, along with limitations of the current DSA practices, and the desired outcomes of DSA. New DSA strategies and tools to address those challenges, e.g., dynamic assessment relying on black-box models, model validation using measurement data, will be explored.

description: Here we develop an original approach to investigate the grand canonical partition function of the multicomponent mixtures of Boltzmann particles with hard-core interaction in finite and even small systems of the volumes above 20 fm$^3$. The derived expressions of the induced surface tension equation of state are analyzed in details. It is shown that the metastable states, which can emerge in the finite systems with realistic interaction, appear at very high pressures at which the hadron resonance gas, most probably, is not applicable at all. It is shown how and under what conditions the obtained results for finite systems can be generalized to include into a formalism the equation for curvature tension. The applicability range of the obtained equations of induced surface and curvature tensions for finite systems is discussed and their close relations to the equations of the morphological thermodynamics are established. The hadron resonance gas model on the basis of the obtained advanced equation of state is worked out. Also, this model is applied to analyze the chemical freeze-out of hadrons and light nuclei with the number of (anti-)baryons not exceeding 4, including the most problematic ratios of hyper-triton and its antiparticle. Their multiplicities were measured by the ALICE Collaboration in the central lead-lead collisions at the center-of-mass energy $\sqrt{s_{\rm NN}} =$ 2.76 TeV.

description: This thesis explores the mechanism of cultural translations of Shakespeare’s plays, which have been frequently performed in Korea and Japan from 2000 to 2014. I particularly focus on the theatrical aesthetic of performers’ bodies to investigate how modern Korean and Japanese directors perceive their own cultural and social contexts as well as Shakespeare’s text. Rather than emphasising the theatrical effect of Shakespeare’s poetic language, modern Korean and Japanese directors have been more concerned with constructing the presence of the actor/character for the history of a theatrical aesthetic emphasising performers’ physical sensibility. In this context, as a symbolic form, the performers’ bodies allow us to re-examine the value of traditional practice and the notion of cultural identity while exploring new ways of performing Shakespeare in line with contemporary audience expectations. Historically, Korea and Japan share several critical moments in adapting Shakespeare from its translation during the period of Japanese colonisation to the dynamic changes of theatre forms and acting styles influenced by avant-garde movements. In many ways, however, Korean and Japanese directors have pursued different approaches in performing Shakespeare based on their indigenous theatrical conventions and cultural contexts. By examining the performers’ physical presentation in eight productions of Shakespeare’s two comedies – A Midsummer Night’s Dream and Twelfth Night – in Korea and Japan, this thesis attempts to deal with two main subjects: the cultural psychology that motivates the directors to portray supernatural aspects of human life; and the concept of gender and sexuality by studying performers’ physical expressions and their semiotic meanings in relation to particular cultural contexts. Through a comparative study between Korean and Japanese productions, this thesis shows how these subjects are explored by each director, looking at the cultural meanings behind their different attitudes and vision in adapting Shakespeare’s plays for a modern theatre.

description: Background
Mycobacterium tuberculosis (M.tb) infection in adults increases incident type 2 diabetes and atherosclerotic cardiovascular disease risk. It is unknown if this cardiometabolic detriment occurs in the young. We investigated whether young persons with latent tuberculosis infection (LTBI) have worse cardiometabolic health than uninfected peers.
Methods
Peripubescent adolescents (12-15 years old) and older adolescents/young adults (16-30 years old) were assessed for LTBI by tuberculin skin testing (induration ≥10mm). Outcomes included fasting plasma glucose (FPG), HbA1c, c-peptide, NTproBNP, hs-Troponin T, CRP, ferritin, diabetes/prediabetes (FPG ≥5.6 mmol/L and/or HbA1c ≥5.7%) and homeostatic model of insulin resistance (HOMA2-IR). LTBI cases were propensity score-matched 1:4 with TB-uninfected controls on sociodemographics to estimate adjusted median (adjMedian), mean differences (adjMD), and odds ratios (adjOR) of cardiometabolic indices.
Results
Seventy-five LTBI cases were matched with 300 TB uninfected peers. Among older participants, LTBI associated with higher inflammation [adjMedian (IQR) CRP: 0.22 (0.05, 0.34) vs. 0.11 (0.04, 0.35) mg/dL; p=0.027; ferritin: 55.0 (25.1, 90.3) vs. 41.1 (29.5, 136.2) ng/mL; p=0.047], but not among peripubescent adolescents. No meaningful differences were observed in FPG [adjMD (95%CI): -0.05 (-0.22, 0.12) mmol/L; p=0.57], HbA1c [0.0 (-0.17, 0.17) %; p=0.98] or diabetes/prediabetes prevalence [adjOR (95%CI): 0.9 (0.29, 2.29); p=0.85], insulin secretion/resistance, NTproBNP, or hs-Troponin T by LTBI status.
Conclusion
Older adolescents and young adults with LTBI had higher inflammation than those without LTBI while cardiometabolic profiles were similar. Unlike adults, M.tb infection in young people may not be associated with cardiometabolic derangement, though the longterm consequences of chronic inflammation require further study.

description: In this paper, we propose a simple yet effective method to deal with the violation of the Closed-World Assumption for a classifier. Previous works tend to apply a threshold either on the classification scores or the loss function to reject the inputs that violate the assumption. However, these methods cannot achieve the low False Positive Ratio (FPR) required in safety applications. The proposed method is a rejection option based on hypothesis testing with probabilistic networks. With probabilistic networks, it is possible to estimate the distribution of outcomes instead of a single output. By utilizing Z-test over the mean and standard deviation for each class, the proposed method can estimate the statistical significance of the network certainty and reject uncertain outputs. The proposed method was experimented on with different configurations of the COCO and CIFAR datasets. The performance of the proposed method is compared with the Softmax Response, which is a known top-performing method. It is shown that the proposed method can achieve a broader range of operation and cover a lower FPR than the alternative.

description: The gamma-ray source 3HWC J1928+178, discovered by HAWC, is coincident with the 82 kyr pulsar PSR J1928+1746, located 4 kpc away. It has not been reported by any Imaging atmospheric Cherenkov Telescope (IACT), until the recent detection of emission from this region by H.E.S.S., using an analysis adapted to extended sources. No counterpart in GeV gamma-rays from Fermi-LAT data or in X-ray has been reported so far. In this contribution, I give the multiwavelength context of the region surrounding 3HWC J1928+178 and present a multi-component model derived using the Multi-Mission Maximum Likelihood framework (3ML). I explore the possibility to model the gamma-ray emission of 3HWC J1928+178 by an extended source with continuous diffuse emission. Together with the age of the pulsar and its extended nature, it may indicate a transition from a pulsar wind nebulae to a halo, where the electrons have started to cool and diffuse away from the source.

description: The traditional oil supply chain suffers from various shortcomings regarding crude oil extraction, processing, distribution, environmental pollution, and traceability. It offers an only a forward flow of products with almost no security and tracking process. In time, the system will lag behind due to the limitations in quality inspection, fraudulent information, and monopolistic behavior of supply chain entities. Inclusion of counterfeiting products and opaqueness of the system urge renovation in this sector. The recent evolution of Industry 4.0 leads to the alternation in the supply chain introducing the smart supply chain. Technological advancement can now reshape the infrastructure of the supply chain for the future. In this paper, we suggest a conceptual framework utilizing Blockchain and Smart Contract to monitor the overall oil supply chain. Blockchain is a groundbreaking technology to monitor and support the security building of a decentralized type supply chain over a peer-to-peer network. The use of the Internet of Things (IoT), especially sensors, opens broader window to track the global supply chain in real-time. We construct a methodology to support reverse traceability for each participant of the supply chain. The functions and characteristics of Blockchain and Smart Contract are defined. Implementation of Smart Contracts has also been shown with detailed analysis. We further describe the challenges of implementing such a system and validate our framework's adaptability in the real world. The paper concludes with future research scope to mitigate the restrictions of data management and maintenance with advanced working prototypes and agile systems achieving greater traceability and transparency.

description: The influence of the pressure of a chemically inert carrier-gas on the nucleation rate is one of the biggest puzzles in the research of gas-liquid nucleation. Different experiments can show a positive effect, a negative effect, or no effect at all. The same experiment may show both trends for the same substance depending on temperature, or for different substances at the same temperature. We show how this ambiguous effect naturally arises from the competition of two contributions: nonisothermal effects and pressure-volume work. Our model clarifies seemingly contradictory experimental results and quantifies the variation of the nucleation ability of a substance in the presence of an ambient gas. Our findings are corroborated by results from molecular dynamics simulation and might have important implications since nucleation in experiments, technical applications, and nature practically always occurs in the presence of an ambient gas.

description: We study pocket universes which have zero cosmological constant and non-trivial boundary topology. These arise from bubble collisions in eternal inflation. Using a simplified dust model of collisions we find that boundaries of any genus can occur. Using a radiation shell model we perform analytic studies in the thin wall limit to show the existence of geometries with a single toroidal boundary. We give plausibility arguments that higher genus boundaries can also occur. In geometries with one boundary of any genus a timelike observer can see the entire boundary. Geometries with multiple disconnected boundaries can also occur. In the spherical case with two boundaries the boundaries are separated by a horizon. Our results suggest that the holographic dual description for eternal inflation, proposed by Freivogel, Sekino, Susskind and Yeh, should include summation over the genus of the base space of the dual conformal field theory. We point out peculiarities of this genus expansion compared to the string perturbation series.

description: The feasibility of chalcogenide rib waveguides working at lambda = 10.6 microns has been demonstrated. The waveguides comprised a several microns thick Te2As3Se5 film deposited by thermal evaporation on a polished As2S3 glass substrate and further etched by physical etching in Ar or CF4/O2 atmosphere. Output images at 10.6 microns and some propagation losses roughly estimated at 10dB/cm proved that the obtained structures behaved as channel waveguides with a good lateral confinement of the light. The work opens the doors to the realisation of components able to work in the mid and thermal infrared up to 20 microns and even more.
