description: We present some preliminary results from an on-going study of the evolution of stellar populations in rich clusters of galaxies. This sample contains core line-strength measurements from 183 galaxies with b_J <= 19.5 from four clusters with ~0.04. Using predictions from stellar population models to compare with our measured line strengths we can derive relative luminosity-weighted mean ages and metallicities for the stellar populations in each of our clusters. We also investigate the Mgb'-sigma and Hbeta_G'-sigma scaling relations. We find that, consistent with previous results, Mgb' is correlated with sigma, the likely explanation being that larger galaxies are better at retaining their heavier elements due to their larger potentials. Hbeta', on the other hand, we find to be anti-correlated with sigma. This result implies that the stellar populations in larger galaxies are older than in smaller galaxies.

description: The article discusses a non-contact control system based on a brain computer interface for a robot cart using Neuroplay-8Cap equipment. This neuroheadset has 8 dry electrodes. To control the robot, 5 commands were used: stop, go forward, go back, turn left, and turn right. The commands are compared with motor imaginary movements of the arms, legs and the inactive phase. To classify EEG data, an algorithm based on Riemannian geometry was used, the maximum accuracy of which was 64.8% for all tests. It is assumed that the classification accuracy can be further improved by optimizing the settings of the Riemannian classifier.

description: The methodology utilized in much of the demand systems literature sets out to empirically test consumer theory in a logical positivist manner, but, inevitably the theory fails. If Karl Popper's agenda were consistently ~pplied the theory would cease to exist. Yet, economists are uneasy about destroying old dictums. So, empirically unsupported theoretical constraints are imposed on the data. If the theory is assumed to always hold ( an apriorist philosophy) then it should not be tested, and should be imposed from the beginning.

 Diagnosis. Pereon depressed, segments 5–7 fused; urosome of 2 segments. Accessory flagellum absent; epistome produced; maXilla 1 inner plate greatly reduced, non-setose, outer plate with 9 spines; maXilla 2 without facial setae; maXilliped palp 4 blunt; gnathopod 2 of female nearly as large as that of male; brood plates on pereopods 2–4; uropod 2 without rami, uropod 3 absent.
 Remarks. Fusion of the cuticle segments of posterior pereonites 5 to 7 is inconsistent within the genus (Laubitz, 1984). Laetmatophilus triceratops sp. nov. has clearly fused pereonites 5 to7 which can be readily observed from the SEM images (Fig. 2A,B).

description: Temporal networks are widely used to represent a vast diversity of systems, including in particular social interactions, and the spreading processes unfolding on top of them. The identification of structures playing important roles in such processes remains largely an open question, despite recent progresses in the case of static networks. Here, we consider as candidate structures the recently introduced concept of span-cores: the span-cores decompose a temporal network into subgraphs of controlled duration and increasing connectivity, generalizing the core-decomposition of static graphs. To assess the relevance of such structures, we explore the effectiveness of strategies aimed either at containing or maximizing the impact of a spread, based respectively on removing span-cores of high cohesiveness or duration to decrease the epidemic risk, or on seeding the process from such structures. The effectiveness of such strategies is assessed in a variety of empirical data sets and compared to baselines that use only static information on the centrality of nodes and static concepts of coreness, as well as to a baseline based on a temporal centrality measure. Our results show that the most stable and cohesive temporal cores play indeed an important role in epidemic processes on temporal networks, and that their nodes are likely to represent influential spreaders.

title: The merchant princes of Nassau: the maintenance of political hegemony in The Bahamas 1834-1948
Creators: name: Themistocleous, Rosalyn
Publisher: name: University of Kent
Year: 2022

description: The former slave owning class in The Bahamas fought a rearguard action to defendits political, economic and social hegemony. It shaped the local Abolition Act of1834 to meet its own requirements, particularly to ensure apprentices would remainin a position of subservience and obedience.The initial period of concern for the welfare and rights of the freedmen onthe part of the Imperial Government soon waned and the white oligarchy was leftto govern the newly emancipated without much interference from London.Imperial Government policy also aided the elite in preventing the formation of aclass of independent, peasant freeholders. On the Out Islands labour orsharecropping tenancies, squatting and the working of commonage were the norm.Coercive labour systems procured a stable and dependent workforce in a number ofindustries. The cash economy was limited outside of Nassau and themerchant/landowners were in possession of the little available capital.Tough laws, designed to keep the lower classes in awe and fear ofauthorities, were passed by a Legislature dominated by the white elite. Much morewas spent on law and order than education or social reforms. The Bahamascontinued to be governed under the seventeenth century Old Representative systemand the ruling class stubbornly protected its rights and privileges. But theconstitutional system was not a responsible one and hardly representative. Openvoting, inequitable constituencies, a franchise weighted in favour of the propertiedclasses, non-payment of representatives and plural voting ensured the return of thewhite Nassau merchants. The agro-commercial elite had a limited vision beyondits own interests, particularly in regard to financial policy. There were manystruggles between the Legislature and the Governors over control of finance andexpenditure, reaching its climax in the 1930s when the Governor insisted onReserve Powers. The Colonial Office investigated the possibilities but realisedthat, barring a crisis, the initiative had to come from the Assembly, which wouldnever have arisen in The Bahamas.The ruling whites experienced little challenge from the coloured and blackmiddle classes. They sought to assimilate themselves into white society anddistanced themselves from the black lower classes. They were generallyconservative in their views. The non-whites did not attempt to form a politicalparty, despite the fact Bahamian society became more polarised in the 1920s and1930s. No leaders emerged to take advantage of the discontent. After the 1942Riot, the ruling whites made a few limited concessions that safeguarded theirdominance

description: In the framework of percolation of color sources, the transverse momentum distribution in heavy ion and $p+p$ collisions at all centralities and energies are shown to follow a universal behaviour. The width of the distribution depends on the fluctuations of the number of color sources per cluster. At low densities, there are only independent single color sources, no fluctuations occurs and the distribution is described by a single exponential. At very high densities, only one cluster of many color sources appears and therefore there are not fluctuations either and the hardness of the distribution is suppressed. The Cronin effect in this framework is due to a maximum of the fluctuations which decreases as the density increases. We obtain a good agreement with experimental data including the low $p_T$ behaviour and the spectra for different particles. We show that the transverse momentum and multiplicity distributions are related to each other in a defined way. This point is satisfied by the experimental data on $p+p$ collisions at different energies.

description: With the 1 ifting of the ban on commodity options, in 1983, new alternatives for marketing soybeans became available. Because options are new there has been 1 imited research on the impact they have on farmers' returns and risk. The objectives of this study were to: 1) test how option strategies perform compared to futures and cash strategies, 2) evaluate strategies that sell options as well as multiple option positions, and 3) compare adjustment strategies to set and hold stfategies. The evaluation criteria were returns measured as the weighted average revenue per bushel, and risk measured as the average negative deviation below total cost of production. This study modeled a Northern Indiana farmer marketing 500 acres of soybeans per year from 1975 to 1988. A computer simulation was developed to evaluate 48 different marketing strategies. The marketing strategies fell in four general classes: 1) Control Strategies, 2) Timing Strategies, 3) Cost of Production Strategies, and 4) Technical Analysis Strategies. Results indicate that options generated 9 of the top 10 revenue producing strategies and 5 of the 10 lowest risk producing strategies. Non-speculative put and call combination strategies achieved near optimum results, while the adjustment by capturing pre-harvest price moves.

description: The dynamics of non-polar diatomic molecules interacting with a far-detuned narrow-band laser field, that only may drive rotational transitions, is studied. The rotation of the molecule is considered both classically and quantum mechanically, providing links to features known from the heavy symmetric top. In particular, quantum decoherence in the molecular rotation, being induced by spontaneous Raman processes, is addressed. It is shown how this decoherence modifies the rotational dynamics in phase space.

title: The impact of energy structure transition on the electric utility industry
Creators: name: Xiong, Chu
Publisher: name: University of Reading
Year: 2025

description: Being the largest emitter of greenhouse gas, the electric utility industry plays a key role 
in the energy structure transition. However, the substantial investment required for the 
transition poses a huge financial challenge for them. This thesis aims to investigate the 
specific impact of energy structure transition on the electric utility industry and seeks 
to provide valuable implications. 
The first study examines the impact of energy structure transition on the electric utilities’
capital structure. It reveals that the inclusion of energy variables improves the average 
leverage prediction accuracy by 12%. Notably, wind (solar) energy negatively
(positively) contributes to firms’ gearing. Next, firms’ leverage adjustment speed is in 
line with the dynamic trade-off theory and adjusts quickly, with a half-life of 0.67 years 
for book leverage. Therefore, electric utilities can use more loans for solar projects and 
internal accruals or alternative financing for wind projects. Effective policies should be 
implemented to encourage the development of green credit and bonds. 
The second study investigates whether energy structure transition affects electric 
utilities’ risk exposure. The results manifest that including the energy variables 
significantly improves the classification accuracy of systematic, idiosyncratic, and total 
risks. Both wind and solar energy show negative correlation with systematic risk. 
Meanwhile, wind (solar) energy is negatively (positively) correlated with idiosyncratic 
and total risks. Given the different impacts of wind and solar energy on systematic and 
idiosyncratic risks, a sophisticated allocation between them should be designed to 
minimise total risk. Further, electric utilities should diversify financing sources beyond 
equity for higher-risk solar projects.
The third study proposes a new business model for electric supply utilities for utilising 
energy storage. The findings confirm that renting cloud energy storage can significantly reduce costs and maximise profits for electricity supply utilities. The biggest saving 
reaches 24.5%. With the rapid fall in battery prices, the proposed strategy will be more 
advantageous.

The first shows that ternary Swap, ternary Not and ternary Toffoli gates are universal for the realization of arbitrary $n\times n$ ternary quantum switching networks without ancilla bits. The second result proves that all $n\times n$ quantum ternary networks can be generated by Not, Controlled-Not, Multiply-Two, and Toffoli gates. Our approach is constructive. key words: ternary quantum logic synthesis, quantum circuit optimization, group theory.

description: The relaxation function theory of doped two-dimensional $S=1/2$ Heisenberg antiferromagnetic (AF) system in the paramagnetic state is presented taking into account the hole subsystem as well as both the electron and AF correlations. The expression for fourth frequency moment of relaxation shape function is derived within the $t-J$ model. The presentation obeys rotational symmetry of the spin correlation functions and is valid for all wave vectors through the Brillouin zone. The spin diffusion contribution to relaxation rates is evaluated and is shown to play a significant role in carrier free and doped antiferromagnet in agreement with exact diagonalization calculations. At low temperatures the main contribution to the nuclear spin-lattice relaxation rate, $^{63}(1/T_1)$, of plane $^{63}$Cu arises from the AF fluctuations, and $^{17}(1/T_1)$, of plane $^{17}$O, has the contributions from the wavevectors in the vicinity of $(π,π)$ and small $q \sim 0$. It is shown that the theory is able to explain the main features of experimental data on temperature and doping dependence of $^{63}(1/T_1)$ in the paramagnetic state of both carrier free La$_2$CuO$_4$ and doped La$_{2-x}$Sr$_x$CuO$_4$ compounds.

De surcroît, les magistris sont le plus souvent désignés par leur seul prénom.

John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Natatolana rekohu Bruce, 2003
 Natatolana rekohu Bruce, 2003: 4, figs. 1–4.
 Type material. Holotype, NIWA H831, male (19.5 mm). Paratypes, NIWA P1380, 533 (18.5, 20.0, 20.5, 23.3, 24.0 [dissected] mm), 13♀♀ (non-ovigerous 17.5–26.5 mm), 3 mancas (8.5, 9.1, 12.0 mm). None examined. Type locality: Chatham Rise, 46°38.24'S 178°31.39'E, 2769 m.
 Material examined. 10, AM P65202, from type locality.
 Diagnosis. Eyes: vestigial. Interocular furrow: moderately developed, distinct but not extending across the cephalon. Frontal lamina: lateral margins concave but not medially constricted, narrowing toward apex. Antenna: c. 0.19× as long as body, reaching to middle of pereonite 3. Coxal plates: furrows strongly developed, on all coxae. Pleonite 2: ventral posterolateral margin not produced. Pleonite 4: apex slightly rounded. Pleotelson: broad, length 0.7× basal width; anterodorsal depression absent; anterolateral margins convex; posterolateral margins convex; apex not produced, lateral margins converging smoothly to a point, or rounded; with 12–18 RS. Pereopod 2: propodus with 3–7 RS on palm. Pereopod 3: propodus with 4 RS on palm. Pereopod 7: basis narrow, width 0.39× length; distance between anterior margin and medial carina less than between posterior margin and medial carina; posterior margin with setae on more than proximal half. Penes: present. Pleopod 2 appendix masculina: just shorter than endopod, 0.9× length of endopod; margins very strongly curved laterally; broad; apex not at angle to adjacent margins, club shaped with a lateral notch. Uropods: exopod slightly shorter than endopod, 0.87× the length of the endopod.
 Size. Males 18.5–24.0mm, females 17.5–24.5mm, both with a mean of 21mm; mancas 8.5–12.0mm.
 Remarks. Natatolana rekohu is most similar to N. imicola. It can be distinguished from that species by (in N. rekohu) the greater number of robust setae on the propodal palm of pereopods 1–3 and the (generally) greater number of robust setae on the margins of the pleotelson and uropods. These two species can be separated from other species of Natatolana in which the eyes are vestigial or absent by: the presence of coxal furrows on all coxae; the distinctive club shaped appendix masculina of male specimens; and the ischium of pereopod 3 having the anterodistal angle not weakly produced relative to that of pereopods 1–2.
 Distribution and ecology. Chatham Rise, southeast of New Zealand. At a depth of 2799 m. Scavenger.

A divergent volume for black holes calls for no "firewall"

description: The presumption that Hawking radiations are thermally distributed can be considered to result from their entanglement with the internal degrees of freedom for a black hole. This leads to the "firewall" paradox if unitary evolution continues into Page's time when a black hole evaporates away half of its initial entropy. However, if the interior of a black hole houses sufficient degrees of freedom to maintain entanglement with the outside at all times, unitarity can be preserved during the complete radiation process and no firewall will be required. This paper proposes a scenario that rescinds firewall by introducing the concept of volume for a black hole. Based on the operational definition by Christodoulou and Rovelli [1], we show that the volume and its associated entropy for a collapsed black hole diverges if the final evaporation stage is treated using noncommutative space. This implicates the interior of a black hole possesses adequate space to store information for a black hole of any mass, like the inside of a "magician's bag".

description: The truck on the UBC farm is nearing the end of its life. It has reached the point where continued maintenance is more costly than the purchase of a replacement. A replacement vehicle that is either a ten passenger van or a small pickup truck is required. Three options were considered to meet this requirement: joining a car co-op and sharing a vehicle over a longer period of time, purchasing a used vehicle that meets the requirements and purchasing a used diesel vehicle that is converted to run on fuel consisting of 20% biodiesel or more. Economically and environmentally, joining a car co-op is worse than buying a used vehicle and there is little if any social benefit. The overall costs were found to be greater than using an used vehicle and the availability of vehicles was poor. Buying a used gasoline vehicle is much cheaper initially than a diesel vehicle, but does not allow for any future conversion to a more environmentally fuel source. Buying a used diesel vehicle and using it without modification allows for the use of B5 biodiesel from plant ops. Conversion to biodiesel allows for the use of higher blends but the benefit of any blend above 20% is overshadowed by the cost and lack of biodiesel sources around campus. A blend of 20% is only provided by UBC’s CHBE Sustainability Club, and is a newly emerging source of biodiesel; however, the biodiesel has not yet reached the market. The recommendation therefore, is to purchase a used diesel vehicle and to use it without modification. If at a future point in time higher blends of biodiesel become economically viable and readily available, the option to modify the vehicle is still open.

description: Quenched lattice-QCD data on the dressed-quark Schwinger function can be correlated with dressed-gluon data via a rainbow gap equation so long as that equation's kernel possesses enhancement at infrared momenta above that exhibited by the gluon alone. The required enhancement can be ascribed to a dressing of the quark-gluon vertex. The solutions of the rainbow gap equation exhibit dynamical chiral symmetry breaking and are consistent with confinement. The gap equation and related, symmetry-preserving ladder Bethe-Salpeter equation yield estimates for chiral and physical pion observables that suggest these quantities are materially underestimated in the quenched theory: || by a factor of two and f_pi by 30%.

description: We discuss the two-photon exchange contribution to observables which involve lepton helicity flip in elastic lepton-nucleon scattering. This contribution is accessed through the spin asymmetry for a lepton beam polarized normal to the scattering plane. We estimate this beam normal spin asymmetry at large momentum transfer using a parton model and we express the corresponding amplitude in terms of generalized parton distributions.

description: The SC and CS stars are thermal-pulsing AGB stars with C/O ratio close to unity. Within this small group, the Mira variable BH Cru recently evolved from spectral type SC (showing ZrO bands) to CS (showing weak C2). Wavelet analysis shows that the spectral evolution was accompanied by a dramatic period increase, from 420 to 540 days, indicating an expanding radius. The pulsation amplitude also increased. Old photographic plates are used to establish that the period before 1940 was around 490 days. Chemical models indicate that the spectral changes were caused by a decrease in stellar temperature, related to the increasing radius. There is no evidence for a change in C/O ratio. The evolution in BH Cru is unlikely to be related to an on-going thermal pulse. Periods of the other SC and CS stars, including nine new periods, are determined. A second SC star, LX Cyg, also shows evidence for a large increase in period, and one further star shows a period inconsistent with a previous determination. Mira periods may be intrinsically unstable for C/O ~ 1; possibly because of a feedback between the molecular opacities, pulsation amplitude, and period. LRS spectra of 6 SC stars suggest a feature at wavelength > 15 micron, which resembles one recently attributed to the iron-sulfide troilite. Chemical models predict a large abundance of FeS in SC stars, in agreement with the proposed association.
