COVID-19 has had a profound impact on society, but also on the operation of the power system. In this panel session we discuss the impact on HVDC systems/technology. Two aspects are covered: the differences in operational practices during the pandemic and new technology options which might get an accelerated breakthrough because of the covid-19 pandemic (e.g. remote maintenance procedures).

description: Airflow through the nasal cavity exhibits a wide variety of fluid dynamicsbehaviour due to the intricacy of the nasal geometry. The flow is naturallyunsteady and perhaps turbulent, despite CFD in the literature that assumesa steady laminar flow. Time-dependent simulations can be used to generatedetailed data with the potential to uncover new flow behaviour, although theyare more computationally intensive compared with steady-state simulations. Furthermore, verification of CFD results has relied on reported pressure drop(e.g. nasal resistance) across the nasal airway although the geometries usedare different. This study investigated the unsteady nature of inhalation atflow rates of 10, 15, 20, and 30 L/min. A scale resolving CFD simulationusing a hybrid RANS-LES model was used and compared with experimentalmeasurements of the pressure distribution and the overall pressure drop in thenasal cavity. The experimental results indicated a large pressure drop acrossthe nasal valve, as well as across the nasopharynx with the latter attributedto a narrow cross-sectional area. At a flowrate of 30 L/min, the CFD simula-tions showed that the anterior half of the nasal cavity displayed dominantlylaminar but disturbed flow behaviour in the form of velocity fluctuations. Theposterior half of the nasal cavity displayed turbulent activity, characterised byerratic fluctuating velocities, which was enhanced by the wider cross-sectionalareas in the coronal plane. At 15L/min, the flow field was laminar dominantwith very little disturbance confirming a steady-state laminar flow assumptionis viable at this flow rate.

description: This paper aims to describe the observable concentration tendencies of media, as important representatives of the cultural and creative industries, in urban centres. Besides the general advantages of urban agglomerations for knowledge-intensive and creative branches this papers highlights the importance of a lively and inspiring urban environment. A further argument for the increasing concentration is seen in the flexible organization of the production system in this industry. Hence, the work in these specific production networks benefits from the opportunities of a heterogeneous urban environment. The ongoing process of concentration is shown by a spatial analysis of employment in media and emphasizes the accomplished arguments.

description: ? Lithothamnion valens
(Fig. 3A, B)
DESCRIPTION
Thallus fruticose, with protuberances 2898-3017 µm in length and 826-1391 µm in diameter. Thallus monomerous, non-coaxial, cell fusions present both in the VC and PF. Cells of the VC measure 16 to 18 µm in length and 8 to 11 µm in diameter (Table 1). Cells of the PF 8 to 15 µm in length and 8 to 10 µm in diameter (Table 1), squarish to rectangular in shape. Conceptacles not observed.
REMARKS
The vegetative anatomy of the described specimens resembles to some extent to that of Lithothamnion valens Foslie (1909) in having large branched thallus, presence of zonation in the PF and numerous and multiple cell fusions (Basso et al. 1997). However, owing to absence of conceptacles, this form is only tentatively assignable to the genus Lithothamnion. Lithothamnion valens is one of the most common species of non-geniculate corallines identified in the Austrian Leitha Limestone (Basso et al. 2008). This species commonly shows a free-living, branching growthform and is endemic in present day Mediterranean Sea. Moussavian (1984) reported its oldest occurrence from the Priabonian of Northern Calcareous Alps. During lower to middle Miocene L. valens was distributed from Iraq to the Tertiary Piedmont Basin. However, the species was restricted to the Mediterranean region starting from the upper Miocene (Basso et al. 1997).

Traditional energy efficiency and demand response programs and measures are not well coordinated; however, a substantial body of emerging research and practical deployments is finding that actions taken to improve building energy efficiency affect demand response capabilities and vice versa. This panel will bring together a group of academic researchers, national laboratory researchers, and industry professionals from the power systems and smart buildings communities to discuss recent findings on the interplay between energy efficiency and demand response, and to propose ways to improve both energy efficiency and demand response through integrated approaches.

Dazu wird eine Systematisierung vorgeschlagen, nach der Bestimmungsgrößen der Clusterentwicklung auf der Ebene der Unternehmen, der Beziehungen und des Clusters als System unterschieden werden. Der theoretisch-konzeptionelle Rahmen wird genutzt, um im Rahmen der zweiten Zielsetzung das Phänomen unterschiedlicher Clusterentwicklungen empirisch zu erklären. Als Beispiel dienen zwei Cluster der Verpackungsmaschinenbau-Industrie in Deutschland, die sich zwischen 1998 und 2010 sehr unterschiedlich entwickelt haben. Methodisch wurde eine Untersuchung an zwei Zeitpunkten durchgeführt. Diese Vorgehensweise hebt sich von den gängigen Studien ab, die in der Regel eine Momentaufnahme des Clusters zum Untersuchungszeitpunkt vornehmen. Demgegenüber konnte umfangreiches Wissen bezüglich der Ausgangsbedingungen zu Beginn des Untersuchungszeitraums genutzt werden und in die Analyse einfließen.

Power grids around the world are experiencing a growing dependence on cyber and physical security concepts to ensure bulk power system reliability and resilience. As the operational technology (OT) and information technology (IT) systems collide, it is becoming increasingly important to ensure that security considerations are integrated into conventional planning, operations, design, and system restoration activities. Examples include supply chain, cloud computing, and other ensuring best cyber practices across the BPS and overall critical infrastructure ecosystem. Further, new and emerging technologies need to be integrated into BPS operations and design in a way that further improves the efficiency of the BPS to serve reliable power to its customers but is also implemented in a cyber-secure manner. This panel will explore these considerations in detail and a panel discussion will highlight key areas of work in this growing field of research and industry implementation.

Autocorrelations and Thermal Fragility of Anyonic Loops in Topologically Quantum Ordered Systems

description: Are systems that display Topological Quantum Order (TQO), and have a gap to excitations, hardware fault-tolerant at finite temperatures? We show that in surface code models that display low d-dimensional Gauge-Like Symmetries, such as Kitaev's and its generalizations, the expectation value of topological symmetry operators vanishes at any non-zero temperature, a phenomenon that we coined thermal fragility. The autocorrelation time for the non-local topological quantities in these systems may remain finite even in the thermodynamic limit. We provide explicit expressions for the autocorrelation functions in Kitaev's model. If temperatures far below the gap may be achieved then these autocorrelation times, albeit finite, can be made large. The physical engine behind the loss of correlations at large spatial and/or temporal distance is the proliferation of topological defects at any finite temperature as a result of a dimensional reduction. This raises an important question: How may we best quantify the degree of protection of quantum information in a topologically ordered system at finite temperature?

The role of photoperiod and endocrine factors in the control of nest-building and courtship in the male ring dove (Streptopelia risoria)
Creators: name: McDonald, Pam
Publisher: name: University of British Columbia
Year: 2010

description: Male ring doves ( Streptopelia risoria ) held on long days perform more nest-building than birds held on short days. This difference persists even if circulating androgen is maintained at similar levels in both groups by castration and treatment with exogenous testosterone. It therefore appears that daylength can alter nest-building through some means other than changes in gonadal androgen production. The experiments described in this thesis examined three mechanisms which might be responsible for the effect of daylength on male nest-building. The first series of experiments tested the hypothesis that nest-building activity is greater under long days as a result of increased aromatization of testosterone into estrogen. Castrated male doves were implanted with estradiol benzoate, testosterone propionate (TP), or a combination of TP and an aromatase inhibitor, ATD, and exposed to either long or short photoperiods. Males held under long days continued to build more actively, regardless of the type of hormone being used. The results thus indicate that differences in the rate of aromatization cannot account for the effect of photoperiod. In a second series of experiments an attempt was made to determine whether an increase in the production of hypothalamic luteinizing hormone releasing hormone (LHRH) under long daylengths stimulates nest-building, as a result of a synergism with testosterone. Long- and short-day castrated males were treated with exogenous TP or TP and LHRH to see if the influence of short daylengths could be reversed by LHRH. LHRH treatment had no effect on the nesting activity of either short- or long-day birds. Finally, several tests were performed which focussed on the role of the pineal gland. Removal of the pineal caused a decrease in nesting activity in long-day birds, but not in short-day birds. The effect of pinealectomy does not depend on the presence of the gonads, since the birds displayed similar responses following castration and testosterone treatment. In the second test, the ability, of pinealectomy to nullify the stimulatory influence of long daylengths was confirmed. In addition, injections of chicken pineal extract increased nest-building in pinealectomized and in short-day pineal-intact birds, suggesting that the pineal produces a substance which is capable of stimulating nesting activity. The identity of this substance is unknown. Pilot tests using melatonin failed to show any stimulatory effect of this compound on nesting behaviour. However, serotonin, which is also present in the pineal in high concentration, did increase nest-building in short-day pinealectomized males. These results indicate that in response to long daylengths the pineal gland of male doves releases a compound, possibly serotonin, which stimulates nest-building activity.
A unified description of diffractive deep inelastic scattering with saturation
Creators: name: Marquet, Cyrille
Publisher: name: arXiv
Year: 2007
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We propose a new description of inclusive diffraction in deep inelastic scattering (DIS). The diffractive structure functions are expressed in the dipole picture and contain heavy-quark contributions. The dipole scattering amplitude, a saturation model fitted on inclusive DIS data, features a saturation scale Q_s(x) larger than 1 GeV for x=10^{-5}. The q\bar{q}g contribution to the diffractive final state is modeled in such a way that both the large-Q^2 and small-beta limits are implemented. In the regime xpom<0.01 in which saturation is expected to be relevant, we obtain a parameter-free description of the HERA data with chi^2/points=1.2.

description: Transverse energy ($E_T$) has been measured with both of its components, namely hadronic ($E_T^{had}$) and electromagnetic ($E_T^{em}$) in a common phase space at mid-rapidity for 62.4 GeV Au+Au collisions by the STAR experiment. $E_T$ production with centrality and $\sqrt{s_{NN}}$ is studied with similar measurements from SPS to RHIC and is compared with a final state gluon saturation model (EKRT). The most striking feature is the observation of a nearly constant value of $E_T/N_{ch} \sim 0.8$ GeV from AGS, SPS to RHIC. The initial energy density estimated by the boost-invariant Bjorken hydrodynamic model, is well above the critical density for a deconfined matter of quarks and gluons predicted by lattice QCD calculations.

description: We report on experiments exploring the physics of dipolar quantum gases using a Chromium Bose-Einstein condensate (BEC). By means of a Feshbach resonance, it is possible to reduce the effects of short range interactions and reach a regime where the physics is governed by the long-range, anisotropic dipole-dipole interaction between the large ($6 μ_{\rm B}$) magnetic moments of Chromium atoms. Several dramatic effects of the dipolar interaction are observed: the usual inversion of ellipticity of the condensate during time-of flight is inhibited, the stability of the dipolar gas depends strongly on the trap geometry, and the explosion following the collapse of an unstable dipolar condensate displays d-wave like features.

DESCRIPTION
Growth form encrusting to foliose, thallus monomerous; the VC is non-coaxial with zonations in PF. The cells of VC more or less rectangular, measuring 16-20 µm in length and 12-14 µm in diameter (Table 1). Peripheral filaments composed of 6 to 12 cells thick, each zone showing a gradual transition of long and short cells, cells of the peripheral filaments measure 8-10 µm in length and 6-9 µm in diameter. Cell fusions present in both VC and PF. Epithallial cells are visible and non-flared in some specimens. Tetra/bisporangial conceptacles are multiporate, buried within the thallus, conceptacle roof distinct, conceptacles raised above the thallus surface. Conceptacle chambers 360 to 480 µm in diameter and 140 to 180 µm in height (Table 1).
REMARKS
The illustrated specimens are similar to the Phymatolithon calcareum (Pallas) Adey & McKibbin described from the upper Miocene of Santa Maria Island, Azores, NE Atlantic Ocean (Rebelo et al. 2014), but the encrusting to foliose growth form does not match the description of P. calcareum, which is commonly fruticose. For this reason, we leave this specimen in open nomenclature. According to Rasser & Piller (1999) the genus Phymatolithon is common in the late Eocene of the Austrian Molasse Zone.

Calibration of the relationship between our PWV measurements and opacity values at 225 GHz was made possible by simultaneous tipping radiometer observations. Based on this calibration, we present Las Campanas Observatory winter-time precipitable water vapor statistics, measured using the tipping radiometer, during a two month campaign. The median value of 2.8 +- 0.3 mm is consistent with that measured at the nearby La Silla Observatory during the VLT site survey.

description: In this paper by using the method of point canonical transformation we find that the Coulomb and Kratzer potentials can be mapped to the Morse potential. Then we show that the Pöschl-Teller potential type I belongs to the same subclass of shape invariant potentials as Hulthén potential. Also we show that the shape-invariant algebra for Coulomb, Kratzer, and Morse potentials is SU(1,1), while the shape-invariant algebra for Pöschl-Teller type I and Hulthén is SU(2).

(Fig. 3E)
DESCRIPTION
Growth form encrusting to warty, thallus measures 1141- 1322 µm in length and 600-715 µm in thickness, monomerous. Cells of the VC are coaxial, more or less rectangular in shape and measures 12 to 24 µm in length and 6 to 10 µm in diameter (Table 1). Cells of the PF are 8 to 25 µm in length and 6 to 20 µm in diameter (Table 1). A wavy zonation is present in the PF. Cell fusions clearly discernible both in the VC and PF. Epithallial cells not clearly visible.
REMARKS
Based on the presence of cell fusions both in VC and PF, zonations in the PF and monomerous thallus with coaxial VC the specimen is confidently assigned to the genus Mesophyllum. The vegetative anatomical features and growth form recall Mesophyllum curtum Lemoine, re-described from the Tortonian of Algeria (Aguirre & Braga 1998) and from the Langhian of southern Moravia, Carpathian Foredeep, Czech Republic (Hrabovský et al. 2015).

description: We report our progress on the development of pixellated imaging CZT detector arrays for our first-generation balloon-borne wide-field hard X-ray (20 - 600 keV) telescope, ProtoEXIST1. Our ProtoEXIST program is a pathfinder for the High Energy Telescope (HET) on the Energetic X-ray Imaging Survey telescope (EXIST), a proposed implementation of the Black Hole Finder Probe. ProtoEXIST1 consists of four independent coded-aperture telescopes with close-tiled (~0.4 mm gaps) CZT detectors that preserve their 2.5mm pixel pitch. Multiple shielding/field-of-view configurations are planned to identify optimal geometry for the HET in EXIST. The primary technical challenge in ProtoEXIST is the development of large area, close-tiled modules of imaging CZT detectors (1000 cm2 for ProtoEXIST1), with all readout and control systems for the ASIC readout vertically stacked. We describe the overall telescope configuration of ProtoEXIST1 and review the current development status of the CZT detectors, from individual detector crystal units (DCUs) to a full detector module (DM). We have built the first units of each component for the detector plane and have completed a few Rev2 DCUs (2x2 cm2), which are under a series of tests. Bare DCUs (pre-crystal bonding) show high, uniform ASIC yield (~70%) and ~30% reduction in electronics noise compared to the Rev1 equivalent. A Rev1 DCU already achieved ~1.2% FWHM at 662 keV, and preliminary analysis of the initial radiation tests on a Rev2 DCU shows ~ 4 keV FWHM at 60 keV (vs. 4.7 keV for Rev1). We therefore expect about

DESCRIPTION
Protuberances with a lumpy growth form.Thallus monomerous with presence of cell fusions in both VC and PF.The VC is coaxial (Fig. 3F) and the cells of VC measure 14-20 µm in length and 8-12 µm in diameter. The cells of PF measuring 14-31 µm in length and 8-28 µm in diameter. Multiporate conceptacles are flat, 229-235 µm in diameter and 71-96 µm in height (Table 1).
REMARKS
The features of thallus organization, growth form, anatomical features and nature of conceptacles are consistent with the description of Mesophyllum roveretoi provided by Basso et al. (2008) from the Miocene “ Lithothamnium Limestone ” of northern Croatia. The taxon stratigraphically ranges from the upper Eocene to the middle Miocene (Conti 1946; Fravega et al. 1987) (Table 2).

description: The unzipping of vortex lines using magnetic-force microscopy from extended defects is studied theoretically. We study both the unzipping isolated vortex from common defects, such as columnar pins and twin-planes, and the unzipping of a vortex from a plane in the presence of other vortices. We show, using analytic and numerical methods, that the universal properties of the unzipping transition of a single vortex depend only on the dimensionality of the defect in the presence and absence of disorder. For the unzipping of a vortex from a plane populated with many vortices is shown to be very sensitive to the properties of the vortices in the two-dimensional plane. In particular such unzipping experiments can be used to measure the ``Luttinger liquid parameter'' of the vortices in the plane. In addition we suggest a method for measuring the line tension of the vortex directly using the experiments.

description: An equivariant bundle gerbe à la Meinrenken over a $G$-manifold $M$ is known to be a special type of $S^1$-gerbe over the differentiable stack $[M/G]$. We prove that the natural morphism relating the Cartan and simplicial models of equivariant cohomology in degree 3 maps the Dixmier-Douady class of an equivariant bundle gerbe à la Meinrenken to the Behrend-Xu-Dixmier-Douady class of the corresponding $S^1$-gerbe.

description: 51. Dunhevedia crassa King, 1853
Localities and specimens found: 30 – 1♀.
Distribution and ecology. It is assumed that D. crassa is distributed throughout the world in warm latitudes, up to the south of temperate regions, but its worldwide populations still need to be revised (Smirnov 1996; Kotov et al. 2013 a, 2013b; Błędzki & Rybak 2016; Korovchinsky et al. 2021b). The species is widely known in the Oriental region (Fernando 1974, 1980; Idris & Fernando 1981; Idris 1983; Michael & Sharma 1988; Sanoamuang 1998; Rane 2002, 2005, 2011; Maiphae et al. 2005, 2008; Chatterjee et al. 2013; Korovchinsky 2013; Van Damme et al. 2013; Ji et al. 2015; Sinev & Yusoff 2015, 2018; Choedchim et al. 2017; Lopez et al. 2017; Sharma & Sharma 2017; Tiang-nga et al. 2020; Choedchim & Maiphae 2023; Dadykin et al. 2023). In Vietnam, it is registered throughout the country (Dang et al. 1980, 2002; Dang & Ho 2001; Sinev & Korovchinsky 2013; Gusakov et al. 2014).
Dunhevedia crassa is a littoral species which occurs, as a rule, in the sites with well developed vegetation in a variety of water bodies (mostly lentic), both permanent and temporary. It can tolerate a fairly high level of salinity (up to 25.9‰) (Idris 1983; Smirnov 1996; Dang & Ho 2001; Sinev & Korovchinsky 2013; Błędzki & Rybak 2016; Korovchinsky et al. 2021b; Choedchim & Maiphae 2023). We found the only female of the species in a small lake located very close to the sea (see Appendix 1).
Remarks. This species was originally described from Australia. On other continents, D. crassa may represent a group of similar species that so far require careful comparative analysis (Smirnov 1996; Kotov et al. 2013b; Korovchinsky et al. 2021b).

Harmonic voltage distortion remains an important issue in power networks and utilities are fully aware of the impact this creates on power quality. With the increasing number of power electronic loads, harmonic interactions and inverter based generation, e.g. PV and wind, the issue is likely to become more exacerbated in the future. The assessment should preferably run continuously with the statistical evaluation of results and not as a single-shot (at certain time instant) or two-step (before and after the connection of installation) procedure. The aim of the panel is to present the main results of the Cigre Working Group C4.42 “ Continuous assessment of low-order harmonic emissions from customer installations, which tackles this issue.
