description: The variability in the infrared to millimetre emission from microquasar GRS 1915+105 is believed to be dominated by the system's relativistic jet. In this paper we develop a time-dependent version of the Blandford & Koenigl (1979) jet emission model and apply it to the oscillations in the infrared and millimetre emission from GRS 1915+105 observed by Fender & Pooley (2000). The resulting model provides a reasonable description of the observed flux oscillations from GRS 1915+105. From a fit of the observed time lag between the flux peaks in the infrared and millimetre emission together with the flux normalisation we were able to determine the model parameters for the GRS 1915+105 jet. We find that to achieve the observed flux levels with the model requires an unphysically large electron density within the jet. We therefore conclude that the Blandford & Koenigl (1979) model cannot explain these observations, either because it does not provide the correct description of the emission from microquasar jets, or because the observed emission variations do not originate in the jet.

description: There is an evident and rapid trend towards the adoption of evaluation exercises for national research systems for purposes, among others, of improving allocative efficiency in public funding of individual institutions. However the desired macroeconomic aims could be compromised if internal redistribution of government resources within each research institution does not follow a consistent logic: the intended effects of national evaluation systems can result only if a "funds for quality" rule is followed at all levels of decision-making. The objective of this study is to propose a bibliometric methodology for: i) large-scale comparative evaluation of research performance by individual scientists, research groups and departments within research institution, to inform selective funding allocations, and ii) assessment of strengths and weaknesses by field of research, to inform strategic planning and control. The proposed methodology has been applied to the hard science disciplines of the Italian university research system for the period 2004-2006.

description: Gravitational radiation tends to drive gravity modes in rotating neutron stars unstable. For an inviscid star, the instability sets in when the rotation frequency is about 0.7 times the corresponding mode frequency of the nonrotating star. Neutron stars with spin frequencies $\go 100$ Hz are susceptible to this instability, with growth time of order years. However, it is likely that viscous dissipation suppresses the instability except for a narrow range of temperatures around $10^9$ K. We also show that the viscosity driven instability of g-modes is absent.

description: Our current research is about speed of time in various celestial bodies (especially planets and stars). The speed of time on celestial bodies (planets or stars) is a new concept which can be simply explained as: - Imagine you have landed on a certain planet and stayed there for some time. And after that you`ve gone to other planet whose size is different from the first planet. In both these cases, you will observe or experience that time is running at different speed, rate or interval. Or you will experience different time speed in both the planets (i.e. time is running faster on one planet and slower on another). This concept is known as the concept of speed of time on a planet. I also called it as “shrest theory”. For example, 1) if you are throwing an exactly same ball at an aim with same magnitude while being at two different planets, then you will observe that the ball will hit aim at different time (i.e. one will hit earlier and other will hit later) due to different value of speed of time in those two planets. 2) If you run/walk on two different planets with same magnitude, you will find that you are taking different time to reach the destination. 3) Astronaut walking on moon with equal magnitude will do movements with different velocity as compared to astronaut walking on earth due to different speed of time. In our research paper, I have mentioned all the factors and quantities on which the speed of time in celestial body depends. We have experimental examples and calculated proofs about my concept (including important formula for calculating speed of time in different planets). The formula of speed of time has expressed the value of speed of time in numerical value with suitable units, symbols and dimensions which are proving 100 % applicable on planets. My concept has revealed various answers about different time speeds occurring in different planets or celestial bodies and could also help us in understanding the nature of time more efficiently. To make this research possible, we have first studied the nature of time in a planet, observed the movements of various planets, collected all data and factors affecting speed of time, conducted several experiments (which is mentioned in my research paper) and finally created an equation/formula for speed of time on a planet. It will be our extreme honor, if higher authorities such as scientists, researchers, experts, explorers and innovative minds will read our concept, refer it for future use and suggest changes if any.

description: 4. Evolvulus ovatus Fernald. (1898: 33).
 Lectotype (designated here):— MEXICO. “ Acapulco, on a shady hillside”, 1894, Edward Palmer 313 (lectotype US00111220 [digital image!], isolectotype, F0054777F [digital image!], GH00054424 [digital image!], K000613105 [digital image!])
 Notes: —When Merritt Lyndon Fernald (1898) described E. ovatus, he mentioned the collection of Edward Palmer 313 without indicating the herbarium where it was housed. We located four specimens from this collection in herbaria F, GH, K and US. We chose the specimen deposited in the US (US 00111220; Fig. 9) as the lectotype because it has more preserved vegetative and reproductive characters, and for being in the herbarium where Edward Palmer deposited his main type collections.
 Morphological relationships and characterization: —This species is easily identified by the stems decumbent to erect, leaves ovate or elliptical, corolla up to 5 mm diameter. It is morphologically similar to E. cordatus, and their relationship is discussed under the comment of this species.
 Distribution and conservation status: — Evolvulus ovatus occurs in Brazil, Colombia, Mexico and Venezuela. In Brazil, it occurs in the northeastern (Ceará, Maranh„o, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas states) and southeastern regions (Minas Gerais State) in caatinga and Atlantic forest domains on sandy soils or rocky outcrops. This species is designated as Least Concern (LC) due to its EOO estimated at 10,017,302.718 km 2. In Brazil, populations of this species were found in a protected area (Floresta Nacional do Araripe in Ceará State).

description: An abnormal frenum affects the gingival health when it is attached too closely to the gingival margin. This may be because the patient fails to control plaque accumulation in the area or due to muscle pull in the maxillary labial region. In addition to this, it may also cause aesthetic concerns or compromise the result of orthodontic treatment for midline diastema and lead to recurrence of such cases. We are hereby presenting ten cases in which five abberant frenums were operated using scalpel and compared with other five frenectomies done using diode laser. Materials and Methods: Ten subjects from the with abnormal frenum attachment in the maxillary anterior region were randomly assigned to have treatment either with a conventional technique or with a diode laser. Comparison of the effects of soft tissue diode laser and the conventional technique on the degree of intra and post?operative bleeding, pain, swelling and wound healing experienced by patients after frenectomy surgery was done. Results: Statistical analysis was done by calculating mean, standard deviation and statistical significance of the data. According to our observation, patients treated with diode laser showed less post-operative bleeding, pain and swelling compared to the scalpel group. There was no statistical significant difference in wound healing in both the groups. Conclusion: Diode laser can be considered as a good option for periodontal surgical procedures as it provides better patient perception and comfort compared to the conventional scalpel technique.

description: Spin-based coherent information processing and encoding utilize the precession phase of spins in magnetic materials. However, the detection and manipulation of spin precession phases remain a major challenge for advanced spintronic functionalities. By using simultaneous electrical and optical detection, we demonstrate the direct measurement of the precession phase of Permalloy ferromagnetic resonance driven by the spin-orbit torques from adjacent heavy metals. The spin Hall angle of the heavy metals can be independently determined from concurrent electrical and optical signals. The stroboscopic optical detection also allows spatially measuring local spin-torque parameters and the induced ferromagnetic resonance with comprehensive amplitude and phase information. Our study offers a route towards future advanced characterizations of spin-torque oscillators, magnonic circuits, and tunnelling junctions, where measuring the current-induced spin dynamics of individual nanomagnets are required.

description: The practice of collaboration, and particularly international collaboration, is becoming ever more widespread in scientific research, and is likewise receiving greater interest and stimulus from policy-makers. However, the relation between research performance and degree of internationalization at the level of single researchers still presents unresolved questions. The present work, through a bibliometric analysis of the entire Italian university population working in the hard sciences over the period 2001-2005, seeks to answer some of these questions. The results show that the researchers with top performance with respect to their national colleagues are also those who collaborate more abroad, but that the reverse is not always true. Also, interesting differences emerge at the sectorial level. Finally, the effect of the nation involved in the international partnership plays a role that should not be ignored.
title: Development participation and adoption intention of ICT for informed decision-making in urban public services: dashboard for Jakarta traffic police patrolling allocations
Creators: name: Syahrial, Taufiq
Publisher: name: University of Glasgow
Year: 2025

description: This thesis investigates the development participation and adoption intention of Information and Communication Technology (ICT) for informed decision-making in urban public services, using a dashboard as an ICT example and Jakarta Traffic Police’s patrolling allocation as the use case of decision-making. This research addresses the gaps in understanding Data-Driven Decision-Making (DDDM) in the public sector and the limited study of government-to-employee (G2E) ICT adoption. It also aims to investigate the underexplored role of user participation in the development and adoption of government ICT. Furthermore, this research underscores the need for qualitative insights to inform the development of quantitative hypotheses, particularly where traditional technology acceptance models like TAM and UTAUT may overlook key public sector contextual factors.

The study is divided into two phases: requirement elicitation and adoption intention examination. In the first phase, semi-structured interviews with Jakarta traffic police were conducted to explore their decision-making processes within a Data-Driven Decision-Making (DDDM) framework and identify preferred features for a user-centred dashboard, leading to the development of a tailored prototype. In the second phase, semi-structured interviews were conducted to develop original hypotheses, focusing on public sector-specific contextual factors. These were then quantitatively tested to examine the factors influencing the traffic police's behavioural intention to adopt the dashboard.

The novel contributions of this research include the development of the original contextual hypotheses and identifying new motivational factors influencing government employees’ ICT adoption, such as interoperability expectations, social incentives, and user experience-related factors. The research also highlights the importance of user participation in enhancing the intention to adopt ICT tools in the public sector. The study provides practical insights for improving public service delivery through data-driven tools and contributes to refining ICT adoption theories in public sector contexts while offering evidence-based recommendations that integrate both technological advancements and human insights to foster more resilient and adaptive decision-making.

description: Context: In Italy, little is known about the territorial distribution of the frailty status. Aims: To compare frailty- and multimorbidity-prevalence in the elderly population of two Italian regions. Methods: This study examined randomized samples of elderly (both community dwelling and institutionalized) assisted by general practitioners. Frailty was evaluated through the CSHA-Scale, multimorbidity through the Charlson-Score. The relation between frailty and multimorbidity was studied through a logistic model. Both crude and standardized prevalences were calculated. Results: One hundred and sixteen physicians assisted 176,503 patients highly representative of Italian people. In a randomized sample of 4,531 older people, the sex–age-standardized prevalence of Frailty (standard population: Italy) was 25.74% (24.63–26.85%). Age-standardized prevalence for males was 20.08% (18.46–21.71%) and 30.00% (28.54–31.57%) for females. Using the sex–age-standardization pooled sample, the prevalence of frailty was significantly higher in Sicily than Veneto (28.74% [27.03–30.46%] vs 22.30% [20.94–23.67%]. This study did not find differences in the prevalence of multimorbidity: Veneto 20.76% (19.21–22.31%); Sicily 22.05% (20.33–23.77%). Both “to be female” and “to live in Sicily” were shown to be predictors of frailty OR for being female = 1.64 (1.42–1.88); OR for living in Sicily = 1.27 (1.11–1.46). Multimorbidity was an independent frailty-predictor only for those aged < 85: OR of Charlson Index ≥ 4 for ages < 85 = 3.44 (2.88–4.11), OR for ages ≥ 85 = 1.44 (0.97–2.12). Limitations: (1) This study considered patients assisted by doctors, not a random sample of the general population. (2) The cross-sectional nature of the study limits the interpretation of the relationships between frailty and multi-morbidity. (3) Few covariates were available for our multivariate models. Conclusions: More than 1/4 of elderly persons are shown to be frail (1/5 of males and 1/3 of females). Frailty is more frequent in Sicily, while multimorbidity does not differ between the two regions. This could be due to regional differences in the organization of care networks dedicated to elderly patients.

description: It is well known that, in the first-order formalism, pure three-dimensional gravity is just the BF theory. Similarly, four-dimensional general relativity can be formulated as BF theory with an additional constraint term added to the Lagrangian. In this paper we show that the same is true also for higher-dimensional Einstein gravity: in any dimension gravity can be described as a constrained BF theory. Moreover, in any dimension these constraints are quadratic in the B field. After describing in details the structure of these constraints, we scketch the ``spin foam'' quantization of these theories, which proves to be quite similar to the spin foam quantization of general relativity in three and four dimensions. In particular, in any dimension, we solve the quantum constraints and find the so-called simple representations and intertwiners. These exhibit a simple and beautiful structure that is common to all dimensions.

We subdivide these transforms into two classes in such a way that the uniform convergence criteria is remarkably different on each class. In more detail, we have the transforms satisfying $μ+ν=0$ (such as the classical Hankel transform), that generalize the cosine transform, and those satisfying $0

description: An information theoretic measure is derived that quantifies the statistical coherence between systems evolving in time. The standard time delayed mutual information fails to distinguish information that is actually exchanged from shared information due to common history and input signals. In our new approach, these influences are excluded by appropriate conditioning of transition probabilities. The resulting transfer entropy is able to distinguish driving and responding elements and to detect asymmetry in the coupling of subsystems.

description: Gaussian Boson Sampling is a model of photonic quantum computing where single-mode squeezed states are sent through linear-optical interferometers and measured using single-photon detectors. In this work, we employ a recent exact sampling algorithm for GBS with threshold detectors to perform classical simulations on the Titan supercomputer. We determine the time and memory resources as well as the amount of computational nodes required to produce samples for different numbers of modes and detector clicks. It is possible to simulate a system with 800 optical modes postselected on outputs with 20 detector clicks, producing a single sample in roughly two hours using $40\%$ of the available nodes of Titan. Additionally, we benchmark the performance of GBS when applied to dense subgraph identification, even in the presence of photon loss. We perform sampling for several graphs containing as many as 200 vertices. Our findings indicate that large losses can be tolerated and that the use of threshold detectors is preferable over using photon-number-resolving detectors postselected on collision-free outputs.

description: Atomistic simulations of thermodynamic properties of magnetic materials rely on an accurate modelling of magnetic interactions and an efficient sampling of the high-dimensional spin space. Recent years have seen significant progress with a clear trend from model systems to material specific simulations that are usually based on electronic-structure methods. Here we develop a Hamiltonian Monte Carlo framework that makes use of auxiliary spin-dynamics and an auxiliary effective model, the temperature-dependent spin-cluster expansion, in order to efficiently sample the spin space. Our method does not require a specific form of the model and is suitable for simulations based on electronic-structure methods. We demonstrate fast warm-up and a reasonably small dynamical critical exponent of our sampler for the classical Heisenberg model. We further present an application of our method to the magnetic phase transition in bcc iron using magnetic bond-order potentials.

description: In a previous paper with Gibbons [CMP 120 (1987) 295] we derived a list of three dimensional symmetric space $σ$-model obtained by dimensional reduction of a class of four dimensional gravity theories with abelian gauge fields and scalars. Here we give a detailed analysis of their group theoretical structure leading to an abstract parametrization in terms of `triangular' group elements. This allows for a uniform treatment of all these models. As an interesting application we give a simple derivation of a `Quadratic Mass Formula' for strictly stationary black holes.

description: In this paper we explore the effects of self-obscuration in protostellar disks with a radially decreasing temperature gradient and a colder midplane. We are motivated by recent reports of resolved dark lanes (`hamburgers') and (sub)mm spectral indices systematically below the ISM value for optically thin dust $α_{\rm ISM} =3.7$. We explore several model grids, scaling disk mass and varying inclination angle $i$ and observing frequency $ν$ from the VLA Ka band ($\sim 37$ GHz) to ALMA Band 8 ($\sim 405$ GHz). We also consider the effects of decreasing the index of the (sub-)mm dust opacity power law $β$ from 1.7 to 1. We find that a distribution of disk masses in the range $M_{\rm disk} = 0.01-2~M_\odot$ is needed to reproduce the observed distribution of spectral indices, and that assuming a fixed $β=1.7$ gives better results than $β=1$. A wide distribution of disk masses is also needed to produce some cases with $α<2$, as reported for some sources in the literature. Such extremely low spectral indices arise naturally when the selected observing frequencies sample the appropriate change in the temperature structure of the optically thick model disk. Our results show that protostellar disk masses could often be underestimated by $> \times10$, and are consistent with recent hydrodynamical simulations. Although we do not rule out the possibility of some grain growth occurring within the short protostellar timescales, we conclude that self-obscuration needs to be taken into account.

De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. 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: We observed the post-common-envelope eclipsing binary with a white dwarf component, QS Vir, using the 1.88 m telescope of Kotammia Observatory in Egypt. The new observations were analyzed together with all multicolor light curves available online (sampling a period of 25 yr), using a full-feature binary system modeling software based on Roche geometry. This is the first time complete photometric modeling was done with most of these data. QS Vir is a detached system, with the red dwarf component underfilling its Roche lobe by a small margin. All light curves feature out-of-eclipse variability that is associated with ellipsoidal variation, mutual irradiation and irregularities in surface brightness of the tidally distorted and magnetically active red dwarf. We tested models with one, two, and three dark spots and found that one spot is sufficient to account for the light curve asymmetry in all data sets, although this does not rule out the presence of multiple spots. We also found that a single spotted model cannot fit light curves observed simultaneously in different filters. Instead, each filter requires a different spot configuration. To thoroughly explore the parameter space of spot locations, we devised a grid-search procedure and used it to find consistent solutions. Based on this, we conclude that the dark spot responsible for light curve distortions has been stable for the past 15 yr, after a major migration that happened between 1993 and 2002, possibly due to a flip-flop event.

description: We show that the Calogero and Calogero-Sutherland models possess an N-body generalization of shape invariance. We obtain the operator representation that gives rise to this result, and discuss the implications of this result, including the possibility of solving these models using algebraic methods based on this shape invariance. Our representation gives us a natural way to construct supersymmetric generalizations of these models, which are interesting both in their own right and for the insights they offer in connection with the exact solubility of these models.

description: Background: High levels of sedentary time increases the risk of cardiovascular disease, including recurrent stroke. Objective: This study aimed to identify factors associated with high sedentary time in community-dwelling people with stroke. Methods: For this data pooling study, authors of published and ongoing trials that collected sedentary time data, using the activPAL monitor, in community-dwelling people with stroke were invited to contribute their raw data. The data was reprocessed, algorithms were created to identify sleep-wake time and determine the percentage of waking hours spent sedentary. We explored demographic and stroke-related factors associated with total sedentary time and time in uninterrupted sedentary bouts using unique, both univariable and multivariable, regression analyses. Results: The 274 included participants were from Australia, Canada, and the United Kingdom, and spent, on average, 69% (SD 12.4) of their waking hours sedentary. Of the demographic and stroke-related factors, slower walking speeds were significantly and independently associated with a higher percentage of waking hours spent sedentary (p = 0.001) and uninterrupted sedentary bouts of >30 and >60 min (p = 0.001 and p = 0.004, respectively). Regression models explained 11–19% of the variance in total sedentary time and time in prolonged sedentary bouts. Conclusion: We found that variability in sedentary time of people with stroke was largely unaccounted for by demographic and stroke-related variables. Behavioral and environmental factors are likely to play an important role in sedentary behavior after stroke. Further work is required to develop and test effective interventions to address sedentary behavior after stroke.

description: Amorphous systems have rapidly gained promise as novel platforms for topological matter. In this work we establish a scaling theory of amorphous topological phase transitions driven by the density of lattice points in two dimensions. By carrying out a finite-size scaling analysis of topological invariants averaged over discrete and continuum random geometries, we discover unique critical properties of Chern and $\mathbb{Z}_2$ glass transitions. Even for short-range hopping models the Chern glass phase may persist down to the fundamental lower bound given by the classical percolation threshold. While the topological indices accurately satisfy the postulated one-parameter scaling, they do not generally flow to the closest integer value in the thermodynamic limit. Furthermore, the value of the critical exponent describing the diverging localization length varies continuously along the phase boundary and is not fixed by the symmetry class of the Hamiltonian. We conclude that the critical behaviour of amorphous topological systems exhibit characteristic features not observed in disordered systems, motivating a wealth of new research directions.

description: Further analysis of X-ray spectroscopy results recently obtained from the MOS CCD cameras on-board XMM-Newton provides a detailed description of the hot and cool X-ray emitting plasma in Cas A. Measurement of the Doppler broadening of the X-ray lines is consistent with the expected ion velocities, ~1500 km/s along the line of sight, in the post shock plasma. Assuming a constant total pressure throughout the remnant we estimate the total remnant mass as 10 Msun and the total thermal energy as 7E43 J. We derive the differential mass distribution as a function of ionisation age for both X-ray emitting components. This distribution is consistent with a hot component dominated by swept up mass heated by the primary shock and a cool component which are ablated clumpy ejecta material which were and are still being heated by interaction with the preheated swept up material. We calculate a balanced mass and energy budget for the supernova explosion giving 1E44 J in ejected mass; approximately 0.4 Msun of the ejecta were diffuse with an initial rms velocity of 15000 km/s while the remaining ~1.8 Msun were clumpy with an initial rms velocity of ~2400 km/s. Using the Doppler velocity measurements of the X-ray spectral lines we can project the mass into spherical coordinates about the remnant. This provides quantitative evidence for mass and energy beaming in the supernova explosion. The mass and energy occupy less than 4.5 sr (<40 % of the available solid angle) around the remnant and 64 % of the mass occurs in two jets within 45 degrees of a jet axis. We calculate a swept up mass of 7.9 Msun in the emitting plasma and estimate that the total mass lost from the progenitor prior to the explosion could be as high as ~20 Msun.

description: In national research assessment exercises that take the peer review approach, research organizations are evaluated on the basis of a subset of their scientific production. The dimension of the subset varies from nation to nation but is typically set as a proportional function of the number of researchers employed at each research organization. However, scientific fertility varies from discipline to discipline, meaning that the representativeness of such a subset also varies according to discipline. The rankings resulting from the assessments could be quite sensitive to the size of the share of articles selected for evaluation. The current work examines this issue, developing empirical evidence of variations in ranking due changes in the dimension of the subset of products evaluated. The field of observation is represented by the scientific production from the hard sciences of the entire Italian university system, from 2001 to 2003.
