description: We use GOODS and CANDELS images to identify progenitors of massive (log M > 10 Msun) compact "early-type" galaxies (ETGs) at z~1.6. Since merging and accretion increase the size of the stellar component of galaxies, if the progenitors are among known star-forming galaxies, these must be compact themselves. We select candidate progenitors among compact Lyman-break galaxies at z~3 based on their mass, SFR and central stellar density and find that these account for a large fraction of, and possibly all, compact ETGs at z~1.6. We find that the average far-UV SED of the candidates is redder than that of the non-candidates, but the optical and mid-IR SED are the same, implying that the redder UV of the candidates is inconsistent with larger dust obscuration, and consistent with more evolved (aging) star-formation. This is in line with other evidence that compactness is a sensitive predictor of passivity among high-redshift massive galaxies. We also find that the light distribution of both the compact ETGs and their candidate progenitors does not show any extended "halos" surrounding the compact "core", both in individual images and in stacks. We argue that this is generally inconsistent with the morphology of merger remnants, even if gas-rich, as predicted by N-body simulations. This suggests that the compact ETGs formed via highly dissipative, mostly gaseous accretion of units whose stellar components are very small and undetected in the HST images, with their stellar mass assembling in-situ, and that they have not experienced any major merging until the epoch of observations at z~1.6.

description: In this work, we propose and explore for the first time a new collider signature of heavy neutral scalars typically found in many distinct classes of multi-Higgs models. This signature, particular relevant in the context of the Large Hadron Collider (LHC) measurements, is based on a topology with two charged leptons and four jets arising from first and second generation quarks. As an important benchmark scenario of the multi-Higgs models, we focus on a recently proposed Branco-Grimus-Lavoura (BGL) type model enhanced with an abelian U(1) flavour symmetry and featuring an additional sector of right-handed neutrinos. We discuss how kinematics of the scalar fields in this model can be used to efficiently separate the signal from the dominant backgrounds and explore the discovery potential of the new heavy scalars in the forthcoming LHC runs. The proposed method can be applied for analysis of statistical significance of heavy scalars' production at the LHC and future colliders in any multi-Higgs model.

description: Chapter 11 is thought to preserve the going-concern surplus of a financially distressed business-the extra value that its assets possess in their current configuration. Financial distress leads to conflicts among creditors that can lead to inefficient liquidation of a business with going-concern surplus. Chapter 11 avoids this by providing the business with a way of fashioning a new capital structure. This account of Chapter 11 fails to capture what is happening in the typical case. The typical Chapter 11 debtor is a small corporation whose assets are not specialized and rarely worth enough to pay tax claims. There is no business worth saving and there are no assets to fight over. The focal point is not the business, but the person who runs it. She is a serial entrepreneur, searching for the business that best matches her skills. For the vast majority of cases, then, Chapter 11 is best seen through the lens of labor economics not corporate finance. Chapter 11 offers the entrepreneur increased liquidity as well as a forum for renegotiating debts (such as unpaid withholding taxes) for which she as well as the corporation are liable. But Chapter 11 offers these benefits only to entrepreneurs who remain with their existing businesses. This lock-in effect is qualitatively no different from the one commonly associated with rent control. These effects, as well as the costs the process imposes on third parties, should be the focus of any assessment of how well Chapter 11 works.

description: Water interactions with organic surfaces are of central importance in biological systems and many Earth system processes. Here we describe experimental studies of water collisions and uptake kinetics on liquid and solid butanol from 160 to 200 K. Hyperthermal D2O molecules (0.32 eV) undergo efficient trapping on both solid and liquid butanol, and only a minor fraction scatters inelastically after an 80% loss of kinetic energy to surface modes. Trapped molecules either desorb within a few ms, or are taken up by the butanol phase during longer times. The water uptake and surface residence time increase with temperature above 180 K indicating melting of the butanol surface 4.5 K below the bulk melting temperature. Water uptake changes gradually across the melting point and trapped molecules are rapidly lost by diffusion into the liquid above 190 K. This indicates that liquid butanol maintains a surface phase with limited water permeability up to 5.5 K above the melting point. These surface observations are indicative of an incremental change from solid to liquid butanol over a range of 10 K straddling the bulk melting temperature, in contrast to the behavior of bulk butanol and previously studied materials.

description: The country can be further assisted to achieve food security by finding a solution to reduce the quantitative and qualitative yields of wheat. Effects of drought stress on the biochemical characteristics of wheat under drought stress conditions were investigated in a factorial experiment as a randomized complete block design with three replications in the research field of the Soil and Water Research Institute in the 2018-2019 and 2019-2020 crop years. Experimental treatments were drought stress at three levels without stress, mild stress, and severe stress with 75, 50, and 25% usable moisture in the soil as the first factor. The second factor was potassium silicate at four levels of a Si-free control, 20 kg/ha as soil application at the bolting stage, and spraying at 2.5 and 5 kg/ha at bolting, heading, and seed dough stages, which were examined in the Sivand wheat cultivar (drought-sensitive) for 2 years.

description: Network analysis was used to study the structure and time evolution of driven three-dimensional complex plasma clusters. The clusters were created by suspending micron-size particles in a glass box placed on top of the rf electrode in a capacitively coupled discharge. The particles were highly charged and manipulated by an external electric field that had a constant magnitude and uniformly rotated in the horizontal plane. Depending on the frequency of the applied electric field, the clusters rotated in the direction of the electric field or remained stationary. The positions of all particles were measured using stereoscopic digital in-line holography. The network analysis revealed the interplay between two competing symmetries in the cluster. The rotating cluster was shown to be more cylindrical than the nonrotating cluster. The emergence of vertical strings of particles was also confirmed.

description: We use properties of doubly-magic nuclei and ab-initio calculations of low-density neutron matter to constrain Skyrme equations of state for neutron-rich conditions. All of these properties are consistent with a Skyrme functional form and a neutron-matter equation of state that depends on three parameters. With a reasonable range for the neutron-matter effective mass, the values of the two other Skyrme parameters are well constrained. This leads to predictions for other quantities. The neutron skins for $^{208}$Pb and $^{48}$Ca are predicted to be 0.182(10) fm and 0.173(5) fm, respectively. Other results including the dipole polarizability are discussed.

description: Neutron irradiation induces in steels nanostructural changes, which are at the origin of the mechanical degradation that these materials experience during operation in nuclear power plants. Some of these effects can be studied by using as model alloy the iron-carbon system. The Object Kinetic Monte Carlo technique has proven capable of simulating in a realistic and quantitatively reliable way a whole irradiation process. We have developed a model for simulating Fe-C systems using a physical description of the properties of vacancy and self-interstitial atom (SIA) clusters, based on a selection of the latest data from atomistic studies and other available experimental and theoretical work from the literature. Based on these data, the effect of carbon on radiation defect evolution has been largely understood in terms of formation of immobile complexes with vacancies that in turn act as traps for SIA clusters. It is found that this effect can be introduced using generic traps for SIA and vacancy clusters, with a binding energy that depends on the size of the clusters, also chosen on the basis on previously performed atomistic studies. The model proved suitable to reproduce the results of low (<350 K) temperature neutron irradiation experiments, as well as the corresponding post-irradiation annealing up to 700 K, in terms of defect cluster densities and size distribution, when compared to available experimental data from the literature. The use of traps proved instrumental for our model.

description: Studies on healthcare quality improvement (QI) increasingly point at the importance of understanding multilevel organizational issues, especially interaction between national, hospital and clinical level. In a EU-study involving ten hospitals in five countries one hospital stood out in successful multilevel QI work, which is elaborated in this paper. It is suggested that there is a potential in using linkages and dependencies in terms of organisational development and resource support (O) and method, process and IT support (T) affecting the individual caregiver (H), to understand the nestedness and interaction between operational system levels in QI.

description: We prove Korovkin-type theorems in the setting of infinite dimensional Hilbert space operators. The classical Korovkin theorem unified several approximation processes. Also, the non-commutative versions of the theorem were obtained in various settings such as Banach algebras, C∗-algebras and lattices etc. The Korovkin-type theorem in the context of preconditioning large linear systems with Toeplitz structure can be found in the recent literature. In this article, we obtain a Korovkin-type theorem on B(H) which generalizes all such results in the recent literature. As an application of this result, we obtain Korovkin-type approximation for Toeplitz operators acting on various function spaces including Bergman space A2(D) , Fock space F2(C) etc. These results are closely related to the preconditioning problem for operator equations with Toeplitz structure on the unit disk D and on the whole complex plane C. It is worthwhile to notice that so far such results are available for Toeplitz operators on circle only. This also establishes the role of Korovkin-type approximation techniques on function spaces with certain oscillation property. To address the function theoretic questions using these operator theory tools will be an interesting area of further research.

description: The fundamental role of on-shell diagrams in quantum field theory has been recently recognized. On-shell diagrams, or equivalently bipartite graphs, provide a natural bridge connecting gauge theory to powerful mathematical structures such as the Grassmannian. We perform a detailed investigation of the combinatorial and geometric objects associated to these graphs. We mainly focus on their relation to polytopes and toric geometry, the Grassmannian and its stratification. Our work extends the current understanding of these connections along several important fronts, most notably eliminating restrictions imposed by planarity, positivity, reducibility and edge removability. We illustrate our ideas with several explicit examples and introduce concrete methods that considerably simplify computations. We consider it highly likely that the structures unveiled in this article will arise in the on-shell study of scattering amplitudes beyond the planar limit. Our results can be conversely regarded as an expansion in the understanding of the Grassmannian in terms of bipartite graphs.

description: Introduction: Work Related Musculoskeletal Disorders (WRMSD) are common in computer users. The aim of this study was to evaluate the role of time related parameters like work experience, duration of computer usage and the periodicity and duration of rest breaks in the predisposition of musculoskeletal pain among Information Technology (IT) professionals. Methodology: Ergonomic workplace analysis reports of 5357 IT professionals from various IT companies in India were reviewed. All the temporal parameters were correlated statistically with perceived pain and discomfort, region of pain and common clinical diagnosis of musculoskeletal disorder. Results: Majority of the respondents were male (71.4%). 2.5% of the workers used the computer for less than 8 hours in a day, 95.8% used it for 8 to 12 hours and remaining used it for more than 12 hours. Prevalence was more among workers who worked more than 8 hours. Neck, low back and wrist were the commonest regions affected respectively.

description: Background: Patient-centeredness (i.e., providing care that is responsive to individual patient preferences) is increasingly recognized as a crucial element of quality of care.

Methods: A six-item patient-centeredness questionnaire was devised to assess the self-perceived needs of ET patients. A link to the questionnaire was included in the monthly e-newsletter of the International Essential Tremor Foundation. The questionnaires were completed online and data were available in electronic format.

Results: There were 1,418 respondents. One in three respondents (i.e., 31.4%) indicated that the doctor was not even “moderately well-educated” about ET. Only 11.8% of respondents were satisfied with their care. Respondents raised a multiplicity of issues that were not being addressed in their current care. The top items were: psychological services and support (33.9%), physical or occupational therapy (28.6%), handling embarrassment and social effects of tremor (15.8%), feelings of not being in control (13.7%), a detailed report and a more quantitative way of assessing tremor and tracking progression (12.7%), better counseling about current treatment and medications (11.9%), empathy, compassion and a feeling of being heard (11.6%), a treatment approach other than just medications and surgery (11.2%), a discussion of all of symptoms aside from tremor (e.g., cognition, balance).

Conclusions: Patients with ET identified a broad range of issues that they felt were not addressed in their treatment; indeed, only one-in-ten patients reporting that they were satisfied with their care. It is hoped that patient-centered approaches such as this will lead to improved models for the care of patients with this common chronic disease.

description: The current research examined gender differences in age difference patterns of self-esteem in Japan. Previous research has shown that self-esteem is high in childhood, decreases in adolescence, and increases gradually in adulthood and old age in Japan. However, gender differences in the pattern of age differences in self-esteem had not been investigated sufficiently. Gender differences are important for understanding human psychology and behavior. Therefore, I analyzed two cross-sectional datasets from large (Study 1: N = 15,965, Study 2: N = 5,258) and diverse samples ranging from elementary school students to older adults in their 60s. Results showed that the patterns of age differences in self-esteem are consistent between males and females. Thus, regarding the global evaluation of the self, males and females show a similar pattern over the life course.

description: BACKGROUND
Despite declines in morbidity and mortality with the use of combination antiretroviral therapy, its effectiveness is limited by adverse events, problems with adherence, and resistance of the human immunodeficiency virus (HIV).
Full Text of Background...
METHODS
We randomly assigned persons infected with HIV who had a CD4+ cell count of more than 350 per cubic millimeter to the continuous use of antiretroviral therapy (the viral suppression group) or the episodic use of antiretroviral therapy (the drug conservation group). Episodic use involved the deferral of therapy until the CD4+ count decreased to less than 250 per cubic millimeter and then the use of therapy until the CD4+ count increased to more than 350 per cubic millimeter. The primary end point was the development of an opportunistic disease or death from any cause. An important secondary end point was major cardiovascular, renal, or hepatic disease.

RESULTS
A total of 5472 participants (2720 assigned to drug conservation and 2752 to viral suppression) were followed for an average of 16 months before the protocol was modified for the drug conservation group. At baseline, the median and nadir CD4+ counts were 597 per cubic millimeter and 250 per cubic millimeter, respectively, and 71.7% of participants had plasma HIV RNA levels of 400 copies or less per milliliter. Opportunistic disease or death from any cause occurred in 120 participants (3.3 events per 100 person-years) in the drug conservation group and 47 participants (1.3 per 100 person-years) in the viral suppression group (hazard ratio for the drug conservation group vs. the viral suppression group, 2.6; 95% confidence interval [CI], 1.9 to 3.7; P<0.001). Hazard ratios for death from any cause and for major cardiovascular, renal, and hepatic disease were 1.8 (95% CI, 1.2 to 2.9; P=0.007) and 1.7 (95% CI, 1.1 to 2.5; P=0.009), respectively. Adjustment for the latest CD4+ count and HIV RNA level (as time-updated covariates) reduced the hazard ratio for the primary end point from 2.6 to 1.5 (95% CI, 1.0 to 2.1).

CONCLUSIONS
Episodic antiretroviral therapy guided by the CD4+ count, as used in our study, significantly increased the risk of opportunistic disease or death from any cause, as compared with continuous antiretroviral therapy, largely as a consequence of lowering the CD4+ cell count and increasing the viral load. Episodic antiretroviral therapy does not reduce the risk of adverse events that have been associated with antiretroviral therapy. (ClinicalTrials.gov number, NCT00027352.)

description: This paper presents a preliminary study into the use of CCDs to image secondary scintillation light generated by THick Gas Electron Multipliers (THGEMs) in a two phase LAr TPC. A Sony ICX285AL CCD chip was mounted above a double THGEM in the gas phase of a 40 litre two-phase LAr TPC with the majority of the camera electronics positioned externally via a feedthrough. An Am-241 source was mounted on a rotatable motion feedthrough allowing the positioning of the alpha source either inside or outside of the field cage. Developed for and incorporated into the TPC design was a novel high voltage feedthrough featuring LAr insulation. Furthermore, a range of webcams were tested for operation in cryogenics as an internal detector monitoring tool. Of the range of webcams tested the Microsoft HD-3000 (model no:1456) webcam was found to be superior in terms of noise and lowest operating temperature. In ambient temperature and atmospheric pressure 1 ppm pure argon gas, the THGEM gain was approximately 1000 and using a 1 msec exposure the CCD captured single alpha tracks. Successful operation of the CCD camera in two-phase cryogenic mode was also achieved. Using a 10 sec exposure a photograph of secondary scintillation light induced by the Am-241 source in LAr has been captured for the first time.

description: The growing movement to make antiretroviral therapy (ART) widely available in South Africa has spurred discussion on different aspects of delivering HIV treatment services, deliberations that have taken on new importance in light of the national government’s recent announcement of a plan to make ART widely available in the public sector. Yet one critical aspect of delivering ART effectively within HIV care services has received surprisingly little attention, namely the challenge of retaining patients in long-term programmes of primary care. Here we discuss the importance of distinguishing adherence to medications from retention in care, as well as the possible interventions that may be employed to improve long-term patient retention.

description: The $N \to Δ$ weak vertex provides an important contribution to the one pion production in neutrino-nucleon and neutrino-nucleus scattering for $πN$ invariant masses below 1.4 GeV. Beyond its interest as a tool in neutrino detection and their background analyses, one pion production in neutrino-nucleon scattering is useful to test predictions based on the quark model and other internal symmetries of strong interactions. Here we try to establish a connection between two commonly used parametrizations of the weak $N \to Δ$ vertex and form factors (FF) and we study their effects on the determination of the axial coupling $C_5^A(0)$, the common normalization of the axial FF, which is predicted to hold 1.2 by using the PCAC hypothesis. Predictions for the $ν_μ p \to μ^- pπ^+$ total cross sections within the two approaches, which include the resonant $Δ^{++}$ and other background contributions in a coherent way, are compared to experimental data.

description: We investigate the impact of non-vanishing net-charge in collision systems on measurements of balance functions and their integrals. We show that the nominal balance function definition yields integrals that deviate from unity because of the non-vanishing net-charge. However, the integral of unified balance functions is shown to appropriately converge to unity when measured in a sufficiently wide experimental acceptance. We furthermore explore the rate of convergence of unified balance functions integrals and study distortions imparted on the shape of balance functions when measurements are carried out in limited transverse momentum ($p_{\rm T}$) and rapidity ($y$) acceptances, such as those featured by experiments at the Large Hadron Collider or the Relativistic Heavy Ion Collider. We show that the shape and integral of unified balance functions may be strongly biased by reductions in the rapidity and transverse momentum acceptances of existing experiments.

description: Darnel ryegrass (Lolium temulentum L.) is an annual long-day plant belonging to the Poaceae family, that common in grain fields worldwide. L. temulentum is a valuable model grass species for studying stress in forage and turf grasses. This study was conducted to study the impact of critical environmental factors on the seed biology of L. temulentum seeds from agricultural districts in southern Iraq were gathered within 2020, and testing was conducted at Erciyes University's Faculty of Agriculture labs in Kayseri. The findings of this study indicated that the seeds of this weed germinate in three days at temperatures between 20 °C and 30 °C, 14 days at 10 to 15 °C, and 28 days at 5 ° C. Furthermore, at a temperature of 35 °C to 40 °C, the seeds did not germinate for 28 days. After 14 days, this species' most significant germination percentage was 91.6 % at 10 °C and 20 °C. Seeds did not germinate when incubated for 14 days under continuous darkness, whereas germinated at 32.5% when subjected to light for 12 h daily. Also, the results showed no significant effect of examined pH and different salinity levels on seed germination of L. temulentum.

description: Sputum smears for acid-fast bacilli (AFB) are the primary methods for diagnosis of tuberculosis (TB) in many countries. The tuberculin skin test (TST) is the primary method for diagnosis of latent TB infection (LTBI) worldwide. The poor sensitivity of the former and the poor specificity of the latter warrant the development of new tests and strategies to enhance diagnostic capabilities. We evaluated the sensitivity of an “in-tube” gamma interferon release assay (IGRA) using TB-specific antigens in comparison to the TST and the sputum smear for AFB in TB cases in South Africa. The sensitivity of the IGRA for TB was considered a surrogate of sensitivity in LTBI. Among 154 patients with a positive culture for Mycobacterium tuberculosis, the sensitivity of the IGRA for the diagnosis of TB varied by clinical subgroup from 64% to 82%, that of the TST varied from 85% to 94%, and that of two sputum smears for AFB varied from 35% to 53%. The sensitivity of the IGRA in human immunodeficiency virus (HIV)-infected TB cases was 81%. HIV-infected TB patients were significantly more likely to have indeterminate IGRA results and produced quantitatively less gamma interferon in response to TB-specific antigens than HIV-negative TB patients. The overall sensitivity of the TST in all TB cases was higher than that of the IGRA (90% versus 76%, respectively). The combined sensitivities of the TST plus IGRA and TST plus a single sputum smear were 96% and 93%, respectively. The TST combined with IGRA or with a single sputum smear may have a role in excluding the diagnosis of TB in some settings.

description: Borderline personality disorder (BPD) is characterized by intense emotions, self-harm, unstable self-image, and risky behaviors, which impede wellness and interfere with occupational participation. However, literature on occupational participation of people with BPD is scarce and has mostly focused on women. This study explores and elucidates intersections of occupational participation and BPD in a sample of mostly male veterans in order to identify potential ways occupational therapists and other health professionals can support wellbeing for this population. Grounded theory analysis was conducted on data collected using the Indiana Psychiatric Illness Interview (IPII), a semi-structured interview designed to elicit illness personal narratives. Analysis yielded three main themes—influencing environment, internal experience, and occupation—and several subthemes including being abused, arising problems, feeling neglected, feeling victimized, escape, self-segregating, positive change, participating/engaging, and substance abuse. Occupations both influenced and were influenced by the environment and internal experiences. Environments appeared to influence internal experience, but internal experiences did not influence environments directly. Rather, internal experiences impacted a person’s occupations which, in turn, impacted their environments. Participants’ occupational lives revealed, as expected, several subthemes depicting negative and/or isolating experiences. However, participants’ occupations directly impacted both their environmental contexts and internal experiences, suggesting occupational performance may be a powerful mechanism of change for this population. Findings offer promise that occupational therapists could facilitate health-promoting occupational participation which, in turn, may result in more positive and health-promoting environments and internal experiences.

description: Apesar dos benefícios e da necessidade para o sector agroalimentar no controlo de diversas pragas e doenças, a utilização excessiva e generalizada de inseticidas convencionais pode ocasionar contaminação ambiental em vários níveis. Nos últimos anos, a aplicação da nanotecnologia tem beneficiado o setor agroalimentar no controlo mais sustentável de pragas, por proporcionar o desenvolvimento de nanopesticidas, em que nanomateriais (NM) permitem a encapsulação e libertação controlada de ingredientes ativos (IA) de inseticidas, direcionando o inseticida para as espécies-alvo e reduzindo assim a contaminação nos ecossistemas e na saúde humana. No entanto, devido à complexidade estrutural e física dos NM produzidos (diferentes materiais, morfologia, tamanho e solubilidade), a maioria dos estudos publicados demonstram a eficácia dos nanopesticidas contra as espécies-alvo, enquanto os ensaios ecotoxicológicos com estes nanopesticidas são muitas vezes escassos e/ou controversos. Neste contexto, a presente revisão destaca os principais materiais utilizados para a produção de nanoinseticidas, discute o seus benefícios e potenciais riscos associados para o meio-ambiente, além de demonstrar estratégias promissoras para o aprimoramento da aplicação de nanoinseticidas no controlo de pragas na agricultura.

description: Background: The p53 tumor suppressor gene is commonly mutated in colorectal cancer. While the effect of p53 mutations on colorectal cancer prognosis has been heavily studied, less is known about how epidemiologic risk factors relate to p53 status, particularly in early colorectal neoplasia prior to clinically invasive colorectal cancer (including adenomas, carcinoma in situ (CIS), and intramucosal carcinoma). Methods: We examined p53 status, as measured by protein overexpression, in 157 cases with early colorectal neoplasia selected from three New York City colonoscopy clinics. After collecting paraffin-embedded tissue blocks, immunohistochemistry was performed using an anti-p53 monoclonal mouse IgG2a [BP53-12-1] antibody. We analyzed whether p53 status was different for risk factors for colorectal neoplasia relative to a polyp-free control group (n = 508). Results: p53 overexpression was found in 10.3%, 21.7%, and 34.9%, of adenomatous polyps, CIS, and intramucosal cases, respectively. Over 90% of the tumors with p53 overexpression were located in the distal colon and rectum. Heavy cigarette smoking (30+ years) was associated with cases not overexpressing p53 (OR = 1.8, 95% CI = 1.1–2.9) but not with those cases overexpressing p53 (OR = 1.0, 95% CI = 0.4–2.6). Heavy beer consumption (8+ bottles per week) was associated with cases overexpressing p53 (OR = 4.0, 95% CI = 1.3–12.0) but not with cases without p53 overexpression (OR = 1.6, 95% CI = 0.7–3.7). Conclusion: Our findings that p53 overexpression in early colorectal neoplasia may be positively associated with alcohol intake and inversely associated with cigarette smoking are consistent with those of several studies of p53 expression and invasive cancer, and suggest that there may be relationships of smoking and alcohol with p53 early in the adenoma to carcinoma sequence.

description: Palo Laziale wood is a small biotope of about 129 ha situated along the north coast of Rome. It is one of the last remaining patches of an ancient lowland floodplain forest that once covered the coastal area of the Lazio region. It contains several habitats and species of high conservation interest which has been included in the Natura2000 network. The forest suffered an impressive dieback event in 2003, coinciding with a particularly hot and dry summer. In the framework of an ecological restoration project (LIFE PRIMED LIFE17 NAT/GR/000511), a preliminary assessment of the biotic and abiotic components of the ecosystem was carried out, including a floristic analysis. This analysis was compared with that conducted in 1990 to assess whether there was any change in the species composition also following the forest dieback. Comparisons between biological forms, chorotypes and the Ellenberg indicators were also made in the analysis. The total flora of the site increased from 462 to 490 species. Moreover, there has been a turnover of species with the disappearance of some grassland and halophytic species and the appearance of allochthonous/ruderal and freshwater habitat species. Despite this, the flora remained unchanged in ecological terms, demonstrating a certain resilience of the plant species, confirming this approach to identify declining processes and support ecosystem-based restoration actions elsewhere.

description: Recent observations of accreting black holes reveal the presence of quasi-periodic oscillations (QPO) in the optical power density spectra. The corresponding oscillation periods match those found in the X-rays, implying a common origin. Among the numerous suggested X-ray QPO mechanisms, some may also work in the optical. However, their relevance to the broadband -- optical through X-ray -- spectral properties have not been investigated. For the first time, we discuss the QPO mechanism in the context of the self-consistent spectral model. We propose that the QPOs are produced by Lense-Thirring precession of the hot accretion flow, whose outer parts radiate in the optical wavelengths. At the same time, its innermost parts are emitting the X-rays, explaining the observed connection of QPO periods. We predict that the X-ray and optical QPOs should be either in phase or shifted by half a period, depending on the observer position. We investigate the QPO harmonic content and find that the variability amplitudes at the fundamental frequency are larger in the optical, while the X-rays are expected to have strong harmonics. We then discuss the QPO spectral dependence and compare the expectations to the existing data.
