description: We calculate some ${\cal O}(α_s^2)$ corrections to the JIMWLK kernel in the framework of the light-cone wave function approach to the high energy limit of QCD. The contributions that we consider originate from higher order corrections in the strong coupling and in the density of the projectile to the solution of the classical Yang-Mills equations of motion that determine the Weizsäcker-Williams fields of the projectile. We study the structure of these corrections in the dipole limit, showing that they are subleading in the limit of large number of colours $N$, and that they cannot be fully recast in the form of dipole degrees of freedom.

description: The challenges of modernizing energy management systems in the face of growing demands for reliability, efficiency, and scalability. Traditional power grids, which are unable to accommodate the integration of renewable energy sources, electric vehicles, and dynamic load demands, are increasingly being replaced by smart grids powered by advanced information and communication technologies (ICTs). Wireless Sensor Networks (WSNs) are pivotal in enabling this transformation. However, WSNs face issues such as high packet loss, electromagnetic interference, and fluctuating link qualities. Furthermore, different smart grid applications have varied Quality of Service (QoS) needs in terms of bandwidth, latency, and reliability. To overcome these challenges, Cognitive Radio Sensor Networks (CRSNs) offer dynamic spectrum access. This article proposes a novel bio-inspired approach combining honey bee mating optimization for routing and cooperative channel assignment to improve CRSN performance. The framework optimizes packet delivery, reduces energy consumption, and meets QoS requirements through dynamic adaptation, as demonstrated by extensive simulations.

description: We investigate the set of completely positive, trace-nonincreasing linear maps acting on the set M_N of mixed quantum states of size N. Extremal point of this set of maps are characterized and its volume with respect to the Hilbert-Schmidt (Euclidean) measure is computed explicitly for an arbitrary N. The spectra of partially reduced rescaled dynamical matrices associated with trace-nonincreasing completely positive maps belong to the N-cube inscribed in the set of subnormalized states of size N. As a by-product we derive the measure in M_N induced by partial trace of mixed quantum states distributed uniformly with respect to HS-measure in $M_{N^2}$.

Dopo aver ripercorso brevemente le fasi di predisposizione del vocabolario, si illustrano alcuni aspetti principali del lemmario: viene evidenziata, giustificata e spiegata la presenza delle voci anche italiane, dei numerosi arcaismi e delle altrettanto frequenti parole del linguaggio giovanile raccolte. Il complesso del lessico romano documentato nel VRC si presenta, dunque, assai stratificato, ma le marche apposte a molti lemmi consentono di collocarli correttamente nel continuum linguistico romano sul piano diastratico e diafasico.

description: With an ever-increasing number of scientific papers published each year, it becomes more difficult for researchers to explore a field that they are not closely familiar with already. This greatly inhibits the potential for cross-disciplinary research. A traditional introduction into an area may come in the form of a review paper. However, not all areas and sub-areas have a current review. In this paper, we present a method for the automatic generation of a review paper corresponding to a user-defined query. This method consists of two main parts. The first part identifies key papers in the area by their bibliometric parameters, such as a graph of co-citations. The second stage uses a BERT based architecture that we train on existing reviews for extractive summarization of these key papers. We describe the general pipeline of our method and some implementation details and present both automatic and expert evaluations on the PubMed dataset.

Finesse and four-wave mixing in microresonators

description: We elaborate a comprehensive theory of the sharp variations of the four-wave-mixing (FWM) threshold happening with the tuning of the pump frequency along the dispersive tails of the nonlinear resonance in the driven Kerr microresonators with high finesses and high finesse dispersions. Our theory leads to the explicit estimates for the difference in the pump powers required for the excitation of one sideband pair with momenta $\pmμ$, and for the simultaneous excitation of the two neighbouring pairs with momenta $\pmμ$, $\pm(μ+1)$. This power difference also measures the depth of the Arnold tongues in the pump-frequency and pump-power parameter space, associated with the aforementioned power variations. A set of select pump frequencies and powers, where the instabilities of the two sideband pairs come first, forms the threshold of complexity, which is followed by a sequence of conditions specifying critical powers for the simultaneous instabilities of three, four and so on pairs. We formally link finesse dispersion and the density of states notion borrowed from the condensed matter context and report a value of the finesse dispersion and a critical mode number signalling the transition from the low- to the high-contrast tongue structure. We also demonstrate that the large finesse dispersion makes possible a surprising for the multimode resonators regime of the bistability without FWM.

description: We examine how water is produced globally over the lunar surface as it orbits in/out of the magnetotail. Due to the interaction of the solar wind (SW) with Earth's magnetic field, upstream the magnetic field is compressed down to ~10 Earth radii. However, the diverted stream of SW around Earth's magnetic field results in an extended depleted region of SW protons (positively charged hydrogen) out to 1000's of Earth radii, referred to as the magnetotail. The Moon orbits at a distance of ~40 Earth radii; therefore, upstream it is within the SW, but downstream it is partially shielded while in the magnetotail during full Moon. SW protons penetrate lunar soil particles and some H atoms can chemical react with oxygen to form water-like molecules such as OH/H2O. Most of the H atoms bounce around within grains until finding another hydrogen atom, chemically combine, and then escape the grain as H2 into the thin atmosphere. We developed a model to calculate the global distribution of OH produced in the lunar surface and H2 released to the atmosphere as the Moon orbits in/out of Earth's magnetotail. The model results are in good agreement with available observations.

What is the meaning of recovery as lived by persons with traumatic brain injury?
Creators: name: Lewington, Philippa J.
Publisher: name: University of British Columbia
Year: 2009

description: To understand the meaning of recovery from traumatic brain injury (TBI) this study sought the perspective of persons living the experience. Each participant was engaged as a co-researcher to make sense of this complex phenomenon. A multiple case study approach was used and seven adults volunteered to share their stories over two interviews. The study produced seven narrative accounts which were the joint product of focused conversation and an explicit, mutual goal. To address the influence of the interviewer, narratives were examined and validated by the participants and by an independent reviewer to ensure they were accurate and complete. Themes emerged through detailed and rigorous analysis of the interviews and narrative accounts. Adherence to protocol, reviews and consultation assured valid results. Themes were compared across accounts and a cyclical and dynamic pattern took form. It incorporated themes of trauma, deconstruction of a previous life story, reconstruction of a new life story and recovery. These themes were interwoven across four streams of life. One was an internal, deeply personal and emotional experience. Another involved external reactions to the events around the person. An interpersonal stream addressed relationships and an intrapersonal stream referred to sense of identity. The results of this study challenge structured stage models described in rehabilitation and brain injury literature. Rather than following clearly-defined steps, the co-researchers described turbulent spirals of trauma, destruction and renewal. Popular theory expounds acceptance and adjustment as a final stage in recovery. The results of this study suggested that the battle to attain such resolution is fought earlier in the story of recovery. Practical implications apply to treatment program design and to individual and group counselling with persons with TBI. The role of the counsellor is crucial to creating a more conjoint approach to treatment. Events which serve to deconstruct and/or reconstruct life stories can be understood collaboratively and constructively in the counselling relationship. The individuals in this study valued empathy, validation, comprehension and control within a treatment plan which maximized recovery potential by assisting them in defining and attaining personal, social and vocational goals.

description: Due to the constant growth of Municipal Solid Waste production, it was deemed necessary to take measures for their proper management, not only in local but also in international level. Therefore, the specialists proposed some integrated Municipal Solid Waste Management Programs and established their legislative framework for their proper function. The main purpose of these programs is to reduce to the minimum the waste products that go for final disposal by sorting, treating and recycling them. The waste treatment method that is analyzed thoroughly in this thesis is the “Composting”. The aim of this study is not only the proper management of Municipal Solid Waste that is produced by the citizens of Amphipolis and N. Zichnis but also the production of a high quality compost, in the lowest possible cost. For the achievement of this goal, the Composting is applied in two hypothetical scenarios so as to be decided which of them is economically and environmentally optimum.
Green's function of a dressed particle

description: We present a new, highly efficient yet accurate approximation for the Green's functions of dressed particles, using the Holstein polaron as an example. Instead of summing a subclass of diagrams (e.g. the non-crossed ones, in the self-consistent Born approximation (SCBA)), we sum all the diagrams, but with each diagram averaged over its free propagators' momenta. The resulting Green's function satisfies exactly the first six spectral weight sum rules. All higher sum rules are satisfied with great accuracy, becoming asymptotically exact for coupling both much larger and much smaller than the free particle bandwidth. Possible generalizations to other models are also discussed.

description: We study the strong coupling behaviour of fixed length single trace operators in the scalar SU(2) sector of ${\cal N} = 4$ SYM. We assume the recently proposed connection with a twisted half-filled Hubbard model. By explicit direct diagonalization of operators with length $L=4, 6, 8$ we study the full {\em perturbative multiplet} of those lattice states which have a clear correspondence with gauge theory composite operators. For this multiplet, we follow the weak-strong coupling flow to free fermion states and identify in particular the precise asymptotic fermion configuration. Next, we analyze the Lieb-Wu equations of the twisted Hubbard model. For the antiferromagnetic state we derive its strong coupling expansion working at $L$ up to 32. We also study the lightest state in the perturbative multiplet. This state is non trivial since involves complex solutions of the Lieb-Wu equations. It is particularly interesting for $AdS_5\times S^5$ duality since it is dual to the folded string semiclassical solution in the thermodynamical limit. We are able to perform the full analysis and compute the next-to-next-to leading terms in the strong coupling expansion for the non trivial lengths L=12 and L=20. A general formula is proposed for the NLO expansion for any $L=4(2k+1)$, $k\in\mathbb{N}$.

The study for that report maps critical stakeholders, highlighting roles and responsibilities. It examines the types of data currently collected, including frequency and quality, and identifies significant trends in data collection. The report also addresses how data are stored, shared and made accessible, revealing systemic issues related to coordination and data transparency. Findings indicate critical gaps in the available data, particularly regarding student access, enrolment for students with disabilities and disaggregation of data on refugees versus nationals. Additionally, there is a need for more data on school dropouts, learning loss and financial matters.Addressing these data gaps is vital to improve the governance and effectiveness of Lebanon’s education system and to shape responsive policies, particularly in crisis contexts. Recommendations focus on the need to enhance data collection, put in place frameworks, clarify roles, improve accessibility and prioritise crisis impact data.
Dynamical Shakeup of Planetary Systems II. N-body simulations of Solar System terrestrial planet formation induced by secular resonance sweeping

description: We revisit the "dynamical shakeup" model of Solar System terrestrial planet formation, wherein the whole process is driven by the sweeping of Jupiter's secular resonance as the gas disk is removed. Using a large number of 0.5 Gyr-long N-body simulations, we investigate the different outcomes produced by such a scenario. We confirm that in contrast to existing models, secular resonance sweeping combined with tidal damping by the disk gas can reproduce the low eccentricities and inclinations, and high radial mass concentration, of the Solar System terrestrial planets. At the same time, this also drives the final assemblage of the planets on a timescale of several tens of millions of years, an order of magnitude faster than inferred from previous numerical simulations which neglected these effects, but possibly in better agreement with timescales inferred from cosmochemical data. In addition, we find that significant delivery of water-rich material from the outer Asteroid Belt is a natural byproduct.

description: Strain is ubiquitous in solid-state materials, but despite its fundamental importance and technological relevance, leveraging externally applied strain to gain control over material properties is still in its infancy. In particular, strain control over the diverse phase transitions and topological states in two-dimensional (2D) transition metal dichalcogenides (TMDs) remains an open challenge. Here, we exploit uniaxial strain to stabilize the long-debated structural ground state of the 2D topological semimetal IrTe$_2$, which is hidden in unstrained samples. Combined angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy (STM) data reveal the strain-stabilized phase has a 6x1 periodicity and undergoes a Lifshitz transition, granting unprecedented spectroscopic access to previously inaccessible type-II topological Dirac states that dominate the modified inter-layer hopping. Supported by density functional theory (DFT) calculations, we show that strain induces a charge transfer strongly weakening the inter-layer Te bonds and thus reshaping the energetic landscape of the system in favor of the 6x1 phase. Our results highlight the potential to exploit strain-engineered properties in layered materials, particularly in the context of tuning inter-layer behavior.

A spectroscopic test of the rotational modulation origin of periodic \emph{Kepler} photometric variability of A-type stars

description: High-precision space-based photometry obtained by the \emph{Kepler} and \emph{TESS} missions has revealed evidence of rotational modulation associated with main sequence (MS) A and late-B type stars. Generally, such variability in these objects is attributed to inhomogeneous surface structures (e.g. chemical spots), which are typically linked to strong magnetic fields ($B\gtrsim100\,{\rm G}$) visible at the surface. It has been reported that $\approx44$~per~cent of all A-type stars observed during the \emph{Kepler} mission exhibit rotationally modulated light curves. This is surprising considering that $\lesssim10$~per~cent of all MS A-type stars are known to be strongly magnetic (i.e. they are Ap/Bp stars). We present a spectroscopic monitoring survey of 44 A and late-B type stars reported to exhibit rotational modulation in their \emph{Kepler} light curves. The primary goal of this survey is to test the hypothesis that the variability is rotational modulation by comparing each star's rotational broadening ($v\sin{i}$) with the equatorial velocities ($v_{\rm eq}$) inferred from the photometric periods. We searched for chemical peculiarities and binary companions in order to provide insight into the origin of the apparent rotational modulation. We find that 14 stars in our sample have $v\sin{i}>v_{\rm eq}$ and/or have low-mass companions that may contribute to or be responsible for the observed variability. Our results suggest that more than $10$~per~cent of all MS A and late-B type stars may exhibit inhomogeneous surface structures; however, the incidence rate is likely $\lesssim30$~per~cent.

description: We have conducted an extensive study using a diverse set of equations of state (EoSs) to uncover strong relationships between neutron star (NS) observables and the underlying EoS parameters using symbolic regression method. These EoS models, derived from a mix of agnostic and physics-based approaches, considered neutron stars composed of nucleons, hyperons, and other exotic degrees of freedom in beta equilibrium. The maximum mass of a NS is found to be strongly correlated with the pressure and baryon density at an energy density of approximately 800 MeV.fm$^{-3}$. We have also demonstrated that the EoS can be expressed as a function of radius and tidal deformability within the NS mass range 1-2$M_\odot$. These insights offer a promising and efficient framework to decode the dense matter EoS directly from the accurate knowledge of NS observables.

description: Using neural networks, we integrate the ability to account for Doppler smearing due to a pulsar's orbital motion with the pulsar population synthesis package \psrpoppy\ to develop accurate modeling of the observed binary pulsar population. As a first application, we show that binary neutron star systems where the two components have highly unequal mass are, on average, easier to detect than systems which are symmetric in mass. We then investigate the population of ultra-compact ($1.5 \, {\rm min} \leq P_{\rm b} \leq 15\,\rm min$) neutron star--white dwarf (NS--WD) and double neutron star (DNS) systems which are promising sources for the Laser Interferometer Space Antenna gravitational-wave detector. Given the non-detection of these systems in radio surveys thus far, we estimate a 95\% confidence upper limit of $\sim$1450 and $\sim$1100 ultra-compact NS--WD and DNS systems in the Milky Way that are beaming towards the Earth respectively. We also show that using survey integration times in the range 20~s to 200~s with time-domain resampling will maximize the signal-to-noise ratio as well as the probability of detection of these ultra-compact binary systems. Among all the large scale radio pulsar surveys, those that are currently being carried out at the Arecibo radio telescope have $\sim$50--80\% chance of detecting at least one of these systems using current integration integration times and $\sim$80--95\% using optimal integration times in the next several years.

description: Solution processable two-dimensional (2D) materials have provided an ideal platform for both fundamental studies and wearable electronic applications. Apart from graphene and 2D dichalcogenides, IVA-VI monochalcogenides (MMCs) has emerged recently as a promising candidate for next generation electronic applications. However, the dispersion behavior, which is crucial for the quality, solubility and stability of MMCs, has been quite unexplored. Here, the exfoliation and the dispersion behavior of Germanium (II) monosulfide (GeS) and Tin (II) monosulfide (SnS) nanosheets has been investigated in a wide range of organic solvents. Nine different organic solvents were examined and analyzed, considering the solvent polarity, surface tension, and Hansen solubility parameters. A significant yield of isolated GeS and SnS flakes, namely ~16.4 and ~23.08 μg/ml in 2-propanol and N-Methyl-2-pyrrolidone respectively were attained. The isolated flakes are few-layers nanosheets with lateral sizes over a few hundreds of nanometers. The MMCs colloids exhibit long-term stability, suggesting the MMCs applicability for scalable solution processable printed electronic device applications.

description: We present a galaxy survey of the field surrounding PKS0405-123 performed with the WFCCD spectrometer at Las Campanas Observatory. The survey is comprised of two datasets: (1) a greater than 95% complete survey to R = 20 of the field centered on PKS0405-123 with 10' radius (L~0.1 L_* and radius of 1Mpc at z=0.1); and (2) a set of four discontiguous (i.e. non-overlapping), flanking fields covering ~1 square degree area with completeness ~90% to R=19.5mag. With these datasets, one can examine the local and large-scale galactic environment of the absorption systems identified toward PKS0405-123. In this paper, we focus on the OVI systems analyzed in Paper I. The results suggest that this gas arises in a diverse set of galactic environments including the halos of individual galaxies, galaxy groups, filamentary-like structures, and also regions devoid of luminous galaxies. In this small sample, there are no obvious trends between galactic environment and the physical properties of the gas. Furthermore, we find similar results for a set of absorption systems with comparable N(HI) but no detectable metal-lines. The observations indicate that metals are distributed throughout a wide range of environments in the local universe. Future papers in this series will address the distribution of galactic environments associated with metal-line systems and the Lya forest based on data for over 10 additional fields. All of the data presented in this paper is made public at a dedicated web site.

title: Collinear Laser Spectroscopy of Magic Lead and Mid-Shell Palladium Isotopes
Creators: name: Renth, Laura
Publisher: name: UNSPECIFIED
Year: 2024

description: Nuclear size and shape are fundamental physical properties defined by the composition of
neutrons and protons within the nucleus. The precise investigation of both properties provides benchmarks for nuclear models and helps to understand the nucleon-nucleon interaction. The nuclear charge radius and the nuclear magnetic dipole and electric quadrupole moments can be probed by the well-known electromagnetic interaction and extracted from atomic spectra. Collinear laser spectroscopy (CLS) is a versatile tool to measure and resolve fine structure and hyperfine structure required to extract the nuclear parameters. It is an in-flight spectroscopy method and therefore very well suited for short-lived isotopes and isomeric states.
A new online collinear laser spectroscopy setup, the Argonne Tandem Hall Laser Beamline
for Atom and Ion Spectroscopy (ATLANTIS) has been commissioned in this work with first
online beams of 110,112−116,118Pd delivered from the Californium Rare Isotope Breader Upgrade (CARIBU). The required high sensitivity for these investigations of palladium isotopes with very low production yields was achieved by a new radio-frequency quadrupole cooler-and-buncher with unprecedented long accumulation times of up to 30 s. A new charge-exchange cell, designed specifically for the charge exchange with magnesium, provided unexpected high neutralization efficiency with almost undisturbed and symmetric resonance profiles.
Using the new setup, spectra of all stable and the neutron-rich 112−116,118Pd isotopes were obtained, the spins of 113,115Pd confirmed, their magnetic dipole moments and the electric quadrupole moment of 113Pd determined, and the trend of the differential nuclear charge radii along the chain of measured isotopes established. The results indicate a complex nuclear structure and are compared to other isotopic chains in the Pd region and to axial Fayans EDF and triaxial Skyrme EDF calculations. The good agreement with the EDF calculations allowing triaxiality, supports the possible existence of triaxial ground states in the mid-shell region between Z=26 and Z=50 and around N=60.
Moreover, CLS measurements were performed at the COLLAPS experiment at ISOLDE/CERN
on semi-magic lead isotopes. The differential mean-square nuclear charge radii and nuclear
moments of 187−208Pb and of the isomeric states of the odd 187−203Pb isotopes were determined. A comparison to Fayans and ab initio calculations show an overall good greement.
Depression in wives of alcoholics : the role of perceived social support from family and friends

description: Perceived social support has been shown to moderate the incidence of depression in the face of adversity in a variety of populations, although this relationship has not been previously verified in a sample of wives of alcoholics. Theory in relation to social support and depression is explored. About twice as many women as men experience depression, and women are more often the providers than the recipients of social support, thus both social support and depression are gender-biased phenomena. The gendered aspects of these constructs are discussed and related to the experience of wives of alcoholics. Work, marriage, and friendships are explored as potential contexts of social support, and a history of professional treatment of wives of alcoholics is reviewed. Professional support has been lacking, and these women have been unjustly pathologized. In a sample of 116 wives of alcoholics, stepwise regression analyses were conducted for two measures of depression as the dependent variables, with perceived social support from family, perceived social support from friends, and various demographic variables as the independent variables. Perceived social support from family was found to explain the majority of the variance for both measures of depression. Perceived social support from friends and unemployment explained additional variance only for the BDI. Number residing in the house explained additional variance only for the SCL-90-R depression subscale. Family income explained additional variance for both measures.

description: Η εργασία αυτή είχε σαν σκοπό να εξετάσει την επίδραση του αζώτου και του φωσφόρου στα πρώτα στάδια δευτερογενούς διαδοχής σε ποώδη φυτοκοινότητα, της οποίας η υπέργεια φυτομάζα απομακρύνονταν στο τέλος του καλοκαιριού ως απομίμηση της βόσκησης, και να διαπιστωθεί εάν υπάρχουν διαφορές με λιβάδια που βρίσκονται σε προχωρημένο στάδιο διαδοχής. Για το σκοπό αυτό εγκαταστάθηκε ένα πείραμα λίπανσης το Σεπτέμβριο του 2007 στο Ταξιάρχη Χαλκιδικής. Η περιοχή χωρίστηκε σε 9 τεμάχια 4 × 5m όπου στο καθένα είχαμε 4 μεταχειρίσεις (μάρτυρας, Ν, Ρ, ΝΡ). Για τρία συνεχόμενα έτη η υπέργεια φυτομάζα συγκομίζονταν, διαχωρίζονταν σε 3 λειτουργικές ομάδες (αγρωστώδη, ψυχανθή και πλατύφυλλα), ξηραίνονταν και ζυγίζονταν. Σημαντικές διαφοροποιήσεις ανάμεσα στα έτη είχαμε τόσο στη παραγωγικότητα όσο και στη σχετική αφθονία των λειτουργικών ομάδων στα αρχικά στάδια της δευτερογενούς διαδοχής. Η αύξηση των φυτών επηρεάστηκε σημαντικά από τις κλιματολογικές συνθήκες καθώς και από την ετερογένεια του εδάφους της περιοχής. Το πρώτο χρόνο είχαμε τη μεγαλύτερη παραγωγικότητα, η οποία σταδιακά μειωνόταν, και τη κυριαρχία των πλατυφύλλων η οποία είχε το ίδιο αποτέλεσμα. Τα επόμενα έτη επικράτησαν τα αγρωστώδη τα οποία φαίνεται να αξιοποιούν καλύτερα τους εδαφικούς πόρους, ειδικά όταν αυτοί είναι περιορισμένοι.
description: This study had as objective to examine the effect of nitrogen and phosphorus in the early stages of secondary succession in an herbaceous plant community, in which the aboveground biomass was removed in late summer as an imitation of grazing, and to determine whether there are differences with meadows that are in an advanced stage of succession.For this purpose a fertilization experiment was established in September 2007 at Taxiarchis in Chalkidiki. The area was divided into 9 plots of 4 × 5m in which each had 4 treatments (control, N, P, NP). For three consecutive years the aboveground biomass was harvested, separated into 3 functional groups (grasses, legumes and forbs), dried and weighed. We had significant differences between the years in both the productivity and the relative abundance of functional groups in the early stages of secondary succession. The plant growth was significantly affected by climatic conditions and the heterogeneity of the soil in the area. The first year we had the greatest productivity, which was gradually decreased, and the dominance of the forbs which had the same result. In the subsequent years the grasses were dominated witch seem to make better use of soil resources, especially when they are limited.
