Published: March 2022

Introduction: The SARS-COV 2 virus, in particular in its severe form, appears to be associated with a large number of thromboembolic events, an incidence all the higher as the patients are admitted to intensive care units or intensive care units. The objective of our work is to identify the prognostic factors for the occurrence of thromboembolic complications of covid 19 in intensive care. Material and method: It is a single-center retrospective study, carried out in the intensive care unit of the IBN TOFAIL hospital in Marrakech. We included all covid 19 patients hospitalized from November 15, 2020 to January 10, 2021 confirmed by RT-PCR or by compatible CT lesions. The qualitative variables were expressed in% and compared by Chi-square test or Fisher's test. The quantitative variables were expressed as a mean (± standard deviation) or as a median (Percentile), and compared by Student's or Mann-Whitney t-test. For multivariate analysis, we used multiple logistic regressions using SPSS version 19 for Windows. A p <0.05 is considered significant. Results: We collected 102 patients hospitalized with SARS-COV 2 pneumonia during the study period. The mean age was 61.81 ± 11 with a predominance of men (65.7%), 45.4% of the patients had a BMI between 30-34.9 Kg / m². Diabetes predominates in 59.8% followed by hypertension in 40.2%, heart disease, dysthyroidism and renal failure were observed in 8.8%, 3.9% and 3.2% of cases, respectively. Forty-two percent of patients presented with coagulopathy on admission, defined by D-Dimer levels> 0.5µg / ml, fibrinogen> 4g / l and thrombocytopenia. The occurrence of an arterial or venous thromboembolic event was found in 24.5% of cases with mainly venous manifestations, i.e. thirteen pulmonary embolisms, three catheter thromboses and two deep vein thromboses and five arterial accidents represented by three ischemic strokes, two limb ischemia and one myocardial infarction. The presence of this coagulopathy associated with ............

Published: March 2022

Background: Assessment of gestational age is important in clinical practice to identify infants at risk for morbidity and mortality related to their gestational age. Globally, LMP date is uncertain or unknown in 20% of pregnant women. In most developing countries, the majority of women are uncertain about LMP and are more likely to be late attendees for prenatal care. In Bangladesh, assessment of gestational age by using NBS, has not been evaluated. Aim: The aim of the study was to validate New Ballard Score (NBS) for assessment of gestational age among Bangladeshi newborns. Methodology: This descriptive cross-sectional study was conducted in the Department of Paediatrics and in the Department of Gynaecology & Obstetrics, Dhaka Medical College Hospital, from January 2014 to June 2014. A total of 100 newborns of both sexes (whose mothers provided exact history of last menstrual period (LMP) and confirmed by prenatal ultrasonography) were included in the study. Prenatal ultrasonography was performed in 17 + 10 weeks (mean + SD) of gestation. Informed consent was taken from all the mothers. Gestational age of the babies was determined on the basis of New Ballard Score. Confirmed gestational age• • by Last Menstrual Period (C-GLMP) was defined as gestational age by Last Menstrual Period confirmed by agreement within two weeks with gestational age by prenatal ultrasonography. The study included assessment of gestational age of newborns by New Ballard Score (NBS), by menstrual history & assessment of confirmed gestational age by menstrual history and by prenatal ultrasonography. Comparison was made between assessed gestational age by NBS and confirmed gestational age by (both LMP and USG) in cases of both preterm and term newborns. Assessed gestational age by NBS and assessed gestational age by menstrual history were also compared with gestational age assessed by USG. Results: The mean (±SD) age of babies examined were 29.6 (±15.2) hr and range 0.5-94 hr. Out of 100 .....

Published: March 2022

A laboratory experiment was carried out to investigate the effect of Thepax and Endo Vit. C as feed additives in the formulated diet on the growth performance of grass carp Ctenopharyngodon idella. The feed (30.11% crude protein) manufactured in the laboratory using raw local materials diet. Young grass carp (Average weight 3.36± 0.95 g) obtained from Aquaculture Unit ponds in Al-Hartha Station for Agricultural Researches, North Basrah. The fish were stocked in nine glass aquarium, three replicates for each treatment, of dimensions 60×40×30 cm provided with pumping aeration. The experimental diets included a control T1 (0% additives), T2 (1g Thepax/kg diet) and T3 (1g Endo Vit. C /kg diet) were used in feeding trail of current experiment. The experiment lasted for 57 days (from 29 Nov. to 24 Jan.) and fishes were fed six days a week using 5% of fish weight as feeding ratio. Results of current study reveals that grass carp fed on formulated feed supplemented with Endo vit. C having high growth performance (WG, DGR, RGR and SGR). The lowest Feed conversion ratio (2.511) was recorded in T3 this value was statistically significant (P≤0.05) with T2 while the highest value (2.767) was observed on the control. Protein efficiency ratio, feed intake and gross conversion efficiency were also recorded high values in T3, but control displayed superior values compared with Thepax treatment, which showed higher value of Relative feed intake compared to other two treatments.

Modular and Fractional $L$-Intersecting Families of Vector Spaces
Authors: Mathew Rogers , Kumar Mishra Tapas , Ray Ritabrata , Srivastava Shashank
Published: March 2022

This paper is divided into two logical parts. In the first part of this paper, we prove the following theorem which is the $q$-analogue of a generalized modular Ray-Chaudhuri-Wilson Theorem shown in [Alon, Babai, Suzuki, J. Combin. Theory Series A, 1991]. It is also a generalization of the main theorem in [Frankl and Graham, European J. Combin. 1985] under certain circumstances. 

$\bullet$ Let $V$ be a vector space of dimension $n$ over a finite field of size $q$. Let $K = \{k_1, \ldots , k_r\},L = \{\mu_1, \ldots , \mu_s\}$ be two disjoint subsets of $\{0,1, \ldots , b-1\}$ with $k_1 < \cdots < k_r$.   Let $\mathcal{F} = \{V_1,V_2,\ldots,V_m\}$ be a family of subspaces of $V$ such that (a) for every $i \in [m]$, dim($V_i$) $\bmod~ b = k_t$, for some $k_t \in K$, and (b) for every distinct $i,j \in [m]$, dim($V_i \cap V_j$)$\bmod~ b =  \mu_t$, for some $\mu_t \in L$. Moreover, it is given that neither of the following two conditions hold:  

$q+1$ is a power of 2, and $b=2$

$q=2, b=6$.

 Then,

$|\mathcal{F}| \leqslant \begin{cases}N(n,s,r,q), & \textrm{ if }\left(s+k_r \leqslant n \textrm { and } r(s-r+1) \leqslant b-1\right) \textrm{ or } (s < k_1 + r)\\ N(n,s,r,q) + \sum_{t \in [r]}\left[\begin{matrix} n \\ k \end{matrix} \right]_{q}, & \textrm{otherwise,} \end{cases}$

where $N(n,s,r,q) := \left[\begin{matrix} n \\ s \end{matrix} \right]_{q} + \left[\begin{matrix} n \\ s-1 \end{matrix} \right]_{q} + \cdots + \left[\begin{matrix} n \\ s-r+1 \end{matrix} \right]_{q}.$  

In the second part of this paper, we prove $q$-analogues of results on a recent notion called fractional $L$-intersecting family of sets for families  of subspaces of a given vector space over a finite field of size $q$. We use the above theorem to obtain a general upper bound to the cardinality of such families. We give an improvement to  this general upper bound in certain special cases.
Sharp Upper and Lower Bounds on a Restricted Class of Convex Characters
Authors: Kelk Steven , Meuwese Ruben
Published: March 2022

Let $\mathcal{T}$ be an unrooted binary tree with $n$ distinctly labelled leaves. Deriving its name from the field of phylogenetics, a convex character on $\mathcal{T}$ is simply a partition of the leaves such that the minimal spanning subtrees induced by the blocks of the partition are mutually disjoint. In earlier work Kelk and Stamoulis (Advances in Applied Mathematics 84 (2017), pp. 34–46) defined $g_k(\mathcal{T})$ as the number of convex characters where each block has at least $k$ leaves. Exact expressions were given for $g_1$ and $g_2$, where the topology of $\mathcal{T}$ turns out to be irrelevant, and it was noted that for $k \geq 3$ topological neutrality no longer holds. In this article, for every $k \geq 3$ we describe tree topologies achieving the maximum and minimum values of $g_k$ and determine corresponding expressions and exponential bounds for $g_k$. Finally, we reflect briefly on possible algorithmic applications of these results.
Cutting a Cake for Infinitely Many Guests
Authors: Jankó Zsuzsanna , Joó Attila
Published: March 2022

Fair division with unequal shares is an intensively studied resource allocation problem. For  $i\in [n] $, let $\mu_i $ be an atomless probability measure on the measurable space $(C,\mathcal{S})$ and let $t_i$ be positive numbers (entitlements) with $\sum_{i=1}^{n}t_i=1$. A fair division is a partition of $C$ into sets $S_i\in \mathcal{S} $ with $\mu_i(S_i)\geq t_i$ for every $i\in [n]$. 

We introduce new algorithms to solve the fair division problem with  irrational entitlements. They are based on the classical Last diminisher technique and we believe that they are simpler than the known methods. Then we show that a fair division always exists even for infinitely many players.
Edge Isoperimetric Inequalities for Powers of the Hypercube
Authors: Rashtchian Cyrus , Raynaud William
Published: March 2022

For positive integers $n$ and $r$, we let $Q_n^r$ denote the $r$th power of the $n$-dimensional discrete hypercube graph, i.e., the graph with vertex-set $\{0,1\}^n,$ where two 0-1 vectors are joined if they are Hamming distance at most $r$ apart. We study edge isoperimetric inequalities for this graph. Harper, Bernstein, Lindsey and Hart proved a best-possible edge isoperimetric inequality for this graph in the case $r=1$. For each $r \geq 2$, we obtain an edge isoperimetric inequality for $Q_n^r$; our inequality is tight up to a constant factor depending only upon $r$. Our techniques also yield an edge isoperimetric inequality for the `Kleitman-West graph' (the graph whose vertices are all the $k$-element subsets of $\{1,2,\ldots,n\}$, where two $k$-element sets have an edge between them if they have symmetric difference of size two); this inequality is sharp up to a factor of $2+o(1)$ for sets of size $\binom{n -s}{k-s}$, where $k=o(n)$ and $s \in \mathbb{N}$.
Decreasing the Maximum Average Degree by Deleting an Independent Set or a $d$-Degenerate Subgraph
Authors: Nadara Wojciech , Smulewicz Marcin
Published: March 2022

The maximum average degree $\mathrm{mad}(G)$ of a graph $G$ is the maximum over all subgraphs of $G$, of the average degree of the subgraph. In this paper, we prove that for every $G$ and positive integer $k$ such that $\mathrm{mad}(G) \ge k$ there exists $S \subseteq V(G)$ such that $\mathrm{mad}(G - S) \le \mathrm{mad}(G) - k$ and $G[S]$ is $(k-1)$-degenerate. Moreover, such $S$ can be computed in polynomial time. In particular, if $G$ contains at least one edge then there exists an independent set $I$ in $G$ such that $\mathrm{mad}(G-I) \le \mathrm{mad}(G)-1$ and if $G$ contains a~cycle then there exists an induced forest $F$ such that $\mathrm{mad}(G-F) \le \mathrm{mad}(G) - 2$. As a side result, we also obtain a subexponential bound on the diameter of reconfiguration graphs of generalized colourings of graphs with bounded value of their $\mathrm{mad}$.
Hidden Discrimination: Designing Culturally Inclusive Service Encounters Using Grounded Theory
Authors: Kim Sun-Hwa , Sebby Angela
Published: March 2022

Few studies have been published about handling intercultural service encounters. The limited prior publications have focused on satisfaction and dissatisfaction and have neglected the concept of inclusivity. This study reveals the sources of discriminatory services to customers who
have limited English proficiency, focusing on those with limited English proficiency, and presents components that can facilitate culturally inclusive service encounters. A combination of lacking intercultural service policies and of language barriers lead to vulnerability among customers
when receiving service. This study has determined that the necessary components for culturally inclusive service encounters are: a) training and granting accessibility at the organizational level and b) patience and creating needs at the individual level. From the perspective of frontline
employees, culturally inclusive service encounters require integration at both organizational and individual levels. Hospitality and tourism organizations are encouraged to train frontline employees on cultural differences and to embrace technologies that enable a realization of service value
among customers with limited English proficiency.
Testing the validity of a self-report scale, author recognition test, and book counting as measures of lifetime exposure to print fiction
Authors: Wimmer Lena , Ferguson Heather J
Published: March 2022

We report a study testing the validity of the three most commonly used indicators of lifetime exposure to print fiction, namely a self-report scale, an author recognition test (ART), and book counting, in a sample of older adults (N=306; Mage = 59.29 years, SDage = 7.01). Convergent validity of the self-report scale and book counting was assessed through correlations with the fiction sub-score of the ART; divergent validity of these two indicators was examined via correlations with the non-fiction sub-score of that ART. We also assessed criterion-related validity by testing the degree to which each of the three indicators predicted participants’ performance in a vocabulary test. The self-report scale and book counting were significantly more positively associated with the ART fiction sub-score than the ART non-fiction sub-score. Regression analyses, controlling for gender and non-fiction exposure, revealed that the ART fiction sub-score had the highest explanatory power among all indicators under investigation for predicting vocabulary test performance. The present results suggest that only ARTs may have satisfactory levels of both construct and criterion-related validity. Recommendations for the assessment of fiction exposure and future directions are discussed.

Published: March 2022

“Nipahol” is high-grade bioethanol produced from nipa sap using the proprietary fermentation and distillation technologies developed by a group of researchers at the Mariano Marcos State University-National Bioenergy Research and Innovation Center (MMSU-NBERIC). To ensure the quality and efficacy of the formulated product, the present study was set to explore the antibacterial potential of the locally formulated nipa disinfectant/antiseptic as an alternative alcohol formulation for possible use during the COVID-19 pandemic using standard microbiological assays. Susceptibility test revealed that at least 70% nipa alcohol formulations showed inhibitory activity against Staphylococcus aureus (6.25 mm and 4.25 mm zone of inhibitions). The 95% nipa alcohol concentration showed a bactericidal effect against Escherichia coli and S. aureus. High percent (%) bacterial cell reduction (90-99.9% log reduction) was observed when alcohol concentration and time increases. A confirmatory antimicrobial susceptibility test conducted by Philippine Department of Science and Technology, Microbiology Division reported that 95% nipa alcohol showed active inhibitory effect to test organisms while partial active observed in 70% nipa alcohol formulation. Glo-Germ Test revealed nipa disinfectant/antiseptic is as effective as commercial alcohol, thus, it can be utilized as an alternative intervention to prevent the spread of infectious microorganisms. The effectiveness of nipa disinfectant/antiseptic formulations is heightened with proper handwashing, strictly following proper hygiene, and health protocols. In conclusion, the formulated nipahol possesses the antibacterial potential to inhibit the multiplication of E. coli and S. aureus.

Confirming the 3:2 Resonance Chain of K2-138

Published: March 2022

The study of orbital resonances allows for the constraint of planetary properties of compact systems. K2-138 is an early K-type star with six planets, five of which have been proposed to be in the longest chain of 3:2 mean motion resonances. To observe and potentially verify the resonant behavior of K2-138's planets, we run N-body simulations using previously measured parameters. Through our analysis, we find that 99.2% of our simulations result in a chain of 3:2 resonances, although only 11% of them show a five-planet resonance chain. We find that we are able to use resonances to constrain the orbital periods and masses of the planets. We explore the possibility of this system forming in situ and through disk migration, and we investigate the potential compositions of each planet using a planet structure code.

We present a dedicated search for new pulsating helium-atmosphere (DBV) white dwarfs from the Sloan Digital Sky Survey using the McDonald 2.1 m Otto Struve Telescope. In total we observed 55 DB and DBA white dwarfs with spectroscopic temperatures between 19,000 and 35,000 K. We find 19 new DBVs and place upper limits on variability for the remaining 36 objects. In combination with previously known DBVs, we use these objects to provide an update to the empirical extent of the DB instability strip. With our sample of new DBVs, the red edge is better constrained, as we nearly double the number of DBVs known between 20,000 and 24,000 K. We do not find any new DBVs hotter than PG 0112+104, the current hottest DBV is at T
eff ≈ 31,000 K, but do find pulsations in four DBVs with temperatures between 27,000 and 30,000 K, improving empirical constraints on the poorly defined blue edge. We investigate the ensemble pulsation properties of all currently known DBVs, finding that the weighted mean period and total pulsation power exhibit trends with effective temperature that are qualitatively similar to the pulsating hydrogen-atmosphere white dwarfs.
Instrumental Tip-of-the-iceberg Effects on the Prompt Emission of Swift/BAT Gamma-ray Bursts

The observed durations of prompt gamma-ray emission from gamma-ray bursts (GRBs) are often used to infer the progenitors and energetics of the sources. Inaccurate duration measurements will have a significant impact on constraining the processes powering the bursts. The “tip-of-the-iceberg” effect describes how the observed signal is lost into background noise; lower instrument sensitivity leads to higher measurement bias. In this study, we investigate how observing conditions, such as the number of enabled detectors, background level, and incident angle of the source relative to the detector plane, affect the measured duration of GRB prompt emission observed with the Burst Alert Telescope on board the Neil Gehrels Swift Observatory (Swift/BAT). We generate “simple-pulse” light curves from an analytical fast rise exponential decay function and from a sample of eight real GRB light curves. We fold these through the Swift/BAT instrument response function to simulate light curves Swift/BAT would have observed for specific observing conditions. We find duration measurements are highly sensitive to observing conditions and the incident angle of the source has the highest impact on measurement bias. In most cases duration measurements of synthetic light curves are significantly shorter than the true burst duration. For the majority of our sample, the percentage of duration measurements consistent with the true duration is as low as ∼25%–45%. In this article, we provide quantification of the tip-of-the-iceberg effect on GRB light curves due to Swift/BAT instrumental effects for several unique light curves.
Magnetic Winding as an Indicator of Flare Activity in Solar Active Regions
Authors: Raphaldini Breno , Prior Christopher B. , MacTaggart David
Published: March 2022

Magnetic helicity is a measure of the entanglement of magnetic field lines used to characterize the complexity of solar active region (AR) magnetic fields. Previous attempts to use helicity-based indicators to predict solar eruptive/flaring events have shown promise but not been universally successful. Here we investigate the use of a quantity associated with the magnetic helicity, the magnetic winding, as a means to predict flaring activity. This quantity represents the fundamental entanglement of magnetic field lines and is independent of the magnetic field strength. We use vector magnetogram data derived from the Helioseismic Magnetic Imager (HMI) to calculate the evolution and distribution of the magnetic winding flux associated with five different ARs, three of them with little flaring activity/nonflaring (AR 11318, AR 12119, AR 12285) and two highly active with X-class flares (AR 11158, AR 12673). We decompose these quantities into “current-carrying” and “potential” parts. It is shown that the ARs that show flaring/eruptive activity have significant contributions to the winding input from the current-carrying part of the field. A significant and rapid input of current-carrying winding is found to be a precursor of flaring/eruptive activity, and, in conjunction with the helicity, sharp inputs of both quantities are found to precede individual flaring events by several hours. This suggests that the emergence/submergence of topologically complex current-carrying field is an important element for the ignition of AR flaring.
Short- and Mid-term Periodicities Observed in Neutron Monitor Counting Rates throughout Solar Cycles 20–24
Authors: López-Comazzi A. , Blanco J. J.
Published: March 2022

This paper examines the short- and mid-term periodicities (≲2 yr) in the cosmic-ray flux along 55 yr, from 1964 to 2019. The cosmic-ray flux has been computed by averaging the counting rates, in typified units, of a set of selected neutron monitors. This builds a representative virtual neutron monitor, named the global neutron monitor. The relevant discovered periodicities are ∼13.5, ∼27, ∼46–64, ∼79–83 day; Rieger-type (∼134–190 days); ∼225–309 day; and ∼1.06–1.15, ∼1.31–1.40, and ∼1.75–2.20 yr periods. The same analyses have been applied to the sunspot number (SSN) with the aim to compare the discovered periodicities and look for possible origins of these periodicities. Two main results have been achieved: the periodicities of 77–83 days, 134–190 days (Rieger type), 225–309 days, ∼1.3 yr, and ∼1.7 yr could be related to the solar dynamo, and an inversely linear relationship has been found between the average of the SSN versus the duration time for each solar cycle of the ∼1.75–2.20 yr period.
On the Application of the Equal-contrast Technique to Ca-K Data from Kodaikanal and Other Observatories

Published: March 2022

The “equal-contrast technique” (ECT) methodology, developed by Singh et al. to generate uniform long time series of Ca-K images obtained during the 20th century from the Kodaikanal Observatory (KO), improved the correlation between the plage area and sunspot parameters. The same methodology can also be used on other observatory data taken with different instruments. We can combine such ECT-corrected images to reduce the gaps in the observations and make a long uniform data set to study short- and long-term variations. We apply this procedure to Mount Wilson Observatory (MWO) historical Ca-K data and recent Ca-K filtergrams obtained using narrowband filters at KO and the Mauna Loa Solar Observatory (MLSO). To determine the success of this method, the results of the analysis of the ECT images obtained from KO, MWO, and MLSO are compared. A comparison of the plage and active areas derived from KO and MWO images before and after the ECT procedure indicates an improvement in the correlation coefficients (CCs) between all the data sets after the ECT application. The CC for the combined monthly mean Ca-K plage area derived from the KO, MWO, and Precision Solar Photometric Telescope (at the MLSO) data with sunspot numbers is 0.96 for the period 1905–2015. The paper demonstrates that the time series of Ca-K data obtained from different instruments after applying the ECT procedure becomes uniform in contrast. The combined time series of KO and MWO spectroheliograms has 12 hr intervals compared to the ≈24 hr gap for a time series from a single observatory.
Compact-object Formation, Retention, and Growth through Accretion onto Gas-embedded White Dwarfs/Neutron Stars in Gas-enriched Globular Clusters
Authors: Perets Hagai B.
Published: March 2022

Observations of pulsars in globular clusters (GCs) give evidence that more than >10%–20% of neutron stars (NSs) that ever formed in GCs were retained there. However, the velocity distribution of field pulsars peaks at 5–10 times the escape velocities of GCs. Consequently, only a small fraction of GC NSs should have been retained, which is potentially difficult to explain even accounting for low-velocity NSs formed through electron-capture supernovae (SNe). Thus, too few low-velocity NSs should have been retained, giving rise to the NS retention problem in GCs. Here we suggest a novel solution, in which the progenitors of most GC NSs were ONe white dwarfs (WDs) that accreted ambient intracluster gas and formed low-velocity NSs through accretion-induced collapse (AIC). The existence of an early gas-enriched environment in GCs is supported by observations of multiple stellar populations in GCs. It is thought that 10–100s of megayears after the formation of the first generation of stars, and after ONe WDs were already formed, GCs were replenished with gas, which formed a second generation of stars. Accretion of such replenished gas onto the ONe WDs catalyzed the AIC processes. The number of AIC-formed NSs is then sufficient to explain the large number of NSs retained in GCs. Similar processes might also drive CO WDs to produce Type Ia SNe or to merge and form NSs and similarly drive NSs to AIC and mergers producing BHs. Moreover, the wide variety of gas-catalyzed binary mergers and explosive transients suggested to occur in the gas-rich environments of an active galactic nucleus disk could similarly, and even more efficiently, occur in second-generation gas in GCs.
Green balance in urban areas as an indicator for policy support: a multi-level application

Published: March 2022

Green spaces are increasingly recognised as key elements in enhancing urban resilience as they provide several ecosystem services. Therefore, their implementation and monitoring in cities are crucial to meet sustainability targets.

In this paper, we provide a methodology to compute an indicator that assesses changes in vegetation cover within Urban Green Infrastructure (UGI). Such an indicator is adopted as one of the indicators for reporting on the key area “nature and biodiversity” in the Green City Accord (GCA).

In the first section, the key steps to derive the indicator are described and a script, which computes the trends in vegetation cover using Google Earth Engine (GEE), is provided.

The second section describes the application of the indicator in a multi-scale, policy-orientated perspective. The analysis has been carried out in 696 European Functional Urban Areas (FUAs), considering changes in vegetation cover inside UGI between 1996 and 2018. Results were analysed for the EU and the United Kingdom. The Municipality of Padua (Italy) is used as a case study to illustrate the results at the local level.

Over the last 22 years, a slight upward trend characterised the vegetation growth within UGI in European FUAs. Within core cities and densily built-upcommuting zones, the trend was stable; in non-densely built-up areas, an upward trend was recorded. Vegetation cover in UGI has been relatively stable in European cities. However, a negative balance between abrupt changes in greening and browning has been recorded, affecting most parts of European cities (75% of core cities and 77% of commuting zones in densely built-up areas). This still indicates ongoing land take with no compensation of green spaces that are lost to artificial areas.

Focusing on the FUA of Padua, a downward trend was observed in 33.3% and 12.9% of UGI in densely built-up and not-densely built-up areas, respectively. Within the FUA of Padua, most municipalities are characterised by a negative balance between abrupt greening and browning, both in non-densely built-up and densely built-up areas.

This approach complements traditional metrics, such as the extent of UGI or tree canopy cover, by providing a valuable measure of condition of urban ecosystems and an instrument to monitor the impact of land take.
