Authors: Yanto Rudi , Meiyanti Ruci
Published: March 2024

The advancement of technology has significantly impacted various aspects of life, including the traditional practice of "arisan marga" among the Batak ethnic group. Despite having been conducted manually for many years, technological progress has opened up opportunities for automation and efficiency improvement through application development. Therefore, this research aims to develop a web-based application for "arisan marga" that utilizes the Linear Congruential Generator (LCG) method for the drawing of arisan recipients and incorporates e-voting for the election of committee members. The development process involves PHP as the base, supported by the Codeigniter framework and MySQL database. The research results demonstrate the application's effectiveness in managing member data, arisan finances, and conducting fair and random arisan drawings. This innovative solution enables the execution of "arisan marga" in a modern manner, allowing for online implementation while maintaining transparency and fostering close relationships among the members. As an effective alternative, this web application can be utilized by the "marga" community to preserve and modernize the tradition of "arisan" digitally.

Authors: Steeg Bas , Esselink Anne , Wit Hugo De , Kramers Cornelis , Bemt Bart van den
Published: March 2024

Aim Recent studies have shown that good adherence cannot be taken for
granted for patients on direct anticoagulants (DOACs). In this
cross-sectional study, adherence among DOAC users was investigated and
associations between beliefs about medication, perceived side effects
and adherence were investigated. Methods We included 100 randomly
selected adult DOAC users visiting one of the two participating Dutch
community pharmacies in the summer of 2020. The self-reported adherence
(primary outcome) was assessed with the Medication Adherence Rating
Scale-5 (MARS-5). Beliefs about DOACs were assessed with the Beliefs
about Medicine Questionnaire Specific (BMQ-S) while side effects were
assessed with a self-developed questionnaire based on the Lareb
Intensive Monitoring (LIM) system. Results Of the participants, 9%
reported non-adherence on the MARS-5 (score <24). Associations
were found between non-adherence and both reported side effects and side
effect burden. Furthermore patients’ belief that DOACs have unpleasant
side effects was associated with both non-adherence and more
side-effects. No associations were found between adherence and either
gender, indication, DOAC or dosage. Conclusion This study confirms that
non-adherence in patients on DOACs is prevalent. We recommend that both
physicians and pharmacists evaluate adherence and side effects with
their DOAC patients on a regular base.

Published: March 2024

Double perovskite (DP) oxides are promising electrode materials for
symmetric solid oxide cells (SSOCs) due to their excellent
electrochemical activity and redox reversibility. B-site cation doping
affects their phase transformation and exsolution properties, which are
crucial for catalyst activation, yet there are few studies. In this
study, the
SrFeCoMoO
(x= 0, 0.1, 0.3, 0.5) DP system demonstrates modulated phase transition
properties by manipulating the oxygen vacancy concentration. The
correlation between Co-doping level and oxygen vacancy concentration is
investigated to optimize the phase transformation and exsolution
properties.
SrFeCoMoO
high density of exsolved CoFe alloy nanoparticles with good phase
stability, and excellent peak power density of 1.27 W
cm (at 850 °C under H fuel cell
mode) and current density of 2.33 A cm (at 1.6 V, 800
°C under HO electrolysis mode). These results
demonstrate a significant role of B-site doping in designing
nanostructured DP materials for high-performed catalysts.

Published: March 2024

The development of switchable solvent-free multicomponent reactions to
build high-value-added products is an important demand for organic
synthesis. Herein, we detailed the successful implementation of a
switchable strategy for the construction of diverse
4-fluoroalkyl-1,4-dihydropyrimidines and 4-fluoroalkyl-pyrimidines via a
solvent/additive-free [3 + 2 + 1] annulation, starting from readily
available enamines, trifluoroacetaldehyde hydrate or
1-ethoxy-2,2-difluoroethanol and amidines hydrochloride. This reaction
conforms to the concept of green synthesis, and provides a new avenue to
access valuable fluorinated heterocycles.

Published: March 2024

Among intracranial embryonal tumors, genetic/epigenetic analysis can
help unveil the molecular background. Herein, we report a case of a
cerebellar pontine angular embryonic tumor complicated by Cowden
syndrome in an infant. The tumor radiologically lacked evidence of
interaction with the cerebellum and appeared to show continuity with the
pons. Pathological appearance was similar to that of a medulloblastoma
with extensive nodularity. DNA methylation analysis indicated that the
tumor was a “medulloblastoma, sonic hedgehog-activated” with a
substantial confidence. Although the diagnosis deviated from the
definition of medulloblastoma, clinical, pathological and molecular data
suggested that it was an “ectopic” medulloblastoma.
Discovery of sesquiterpenoids from Chloranthus henryi Hemsl. var. hupehensis (Pamp.)K. F. Wu and their anti-inflammatory activity by suppression of the IKBα/NF-κB p65 signaling pathway

Published: March 2024

The phytochemical investigation of the roots of Chloranthus henryi
Hemsl. var. hupehensis (Pamp.) K. F. Wu led to the isolation and
identification of 23 structurally diverse sesquiterpenes and their
dimer, including a new eudesmane sesquiterpenoid dimer, nineteen new
sesquiterpenoids and three known sesquiterpenoids. Among the isolates, 1
was a rare sesquiterpenoid dimer formed by assembling two highly
rearranged eudesmane-type sesquiterpenes through a unique oxygen bridge
(C-11–O–C-8′). It is worth noting that rearranged eudesmane type
sesquiterpenoid dimers containing an oxygen bridge are rarely isolated
from nature. (+)-2 and (−)-2 were a pair of new skeleton
sesquiterpenoids with a remarkable 6/6/5 tricyclic ring framework
including one γ-lactone ring and the bicyclo[3.3.1]nonane core.
Their structures and absolute configurations were determined by
spectroscopic analysis, single-crystal X-ray diffraction analysis, and
quantum chemical calculation. Moreover, all the isolated compounds were
evaluated for their potential anti-inflammatory activity using an
LPS-induced BV-2 cell microglial. Among them, 18 suppressed TNF-α and
IL-1β expression with EC50 values of 6.81 µM and 2.76 µM, respectively,
indicating its excellent efficacy in inhibiting inflammatory factors
production. In subsequent mechanism studies, compounds 3, 17, and 18
could reduce the production of IL-1β and TNF-α by inhibiting the
activation of IKBα/p65 pathway.
Stochastic Distributed Tracking of Heterogeneous Multi-Agent Systems with Markovian Switching Topologies and Infinite Delays
Authors: Guo Haihua , Feng Gang , BI Cong
Published: March 2024

This paper investigates the distributed mean square output tracking
problem of heterogeneous multi-agent systems with Markovian switching
topologies and infinite transmission delays. The main challenge of the
concerned problem arises from how to deal with Markovian switching
topologies and infinite transmission delays simultaneously. A novel
distributed observer is developed based on a newly proposed Lyapunov
functional method. Then, a distributed controller based on the
distributed observer is developed. It is shown that the stochastic
distributed tracking problem is solved in the sense of mean square if
the union graph of the underlying Markovian switching topology contains
a spanning tree. A distinctive feature of the proposed controller is
that the infinite delays are not required to be known. Finally, the
effectiveness of the proposed controller is illustrated by two numerical
examples.
Genetic and phenotypic differentiation in a Neotropical passerine with a disjunct distribution in the Andean and Atlantic forests (Thamnophilus ruficapillus)
Authors: Bukowski Belén , Campagna Leonardo , Cabanne Gustavo , Tubaro Pablo , Lijtmaer Darío
Published: March 2024

The Andean and Atlantic forests are separated by the open vegetation
corridor, which acts as a geographic barrier. However, these forests
experimented cycles of connection and isolation in the past which shaped
the phylogeographic patterns of their biotas. We analyzed the
evolutionary history of the Rufous-capped Antshrike (Thamnophilus
ruficapillus), a species with a disjunct distribution in the Atlantic
and Andean forests and therefore an appropriate model to study the
effect of the open vegetation corridor and the Andes on the
diversification of the Neotropical avifauna. We performed a
phylogenetic/phylogeographic analysis including the five subspecies,
using mitochondrial and nuclear genomic DNA, and also studied their
differences in vocalizations and plumage coloration. Both the
mitochondrial and nuclear DNA evidenced a marked phylogeographic
structure with three differentiated lineages that diverged without gene
flow in the Pleistocene (1.0-1.7 million years ago): one in the Atlantic
Forest and two in the Andean forest. However, the two Andean lineages do
not coincide with the two disjunct areas of distribution of the species
in the Andes. Vocalizations were significantly different between most
subspecies, but their pattern of differentiation was discordant with
that of the nuclear and mitochondrial DNA. In fact, there is no song
differentiation between the subspecies of the Atlantic Forest and that
of the northwestern Bolivian Andes, even though they differ genetically
and belong to different lineages. Consistently, no differences were
found in plumage coloration between the subspecies of the Atlantic
Forest and that of the southern Andes. Our results suggest a complex
evolutionary history in this species, which differentiated both due to
dispersion across the open vegetation corridor, likely during a period
of connection between the Andean and Atlantic forests, and as a
consequence of a geographic barrier in northern Bolivia. In both cases
Pleistocene climatic oscillations appear to have influenced the species
diversification.

In recent years, with the updating and iterating of new global
technologies, digital twins (DTs) originated in the aerospace industry
has been widely used in smart manufacturing, smart construction, and
smart management as a new type of informatization management tool. It is
therefore important for scholars to understand the current state of
research on DTs to conduct more targeted research in the future. Based
on Scopus, 7384 publications related to DTs were found from 1951 to 2023
in this study. With VOSviewers, the major countries, authors, and
institutions researching DTs globally were analyzed and discussed. In
conclusion, the study found that since 2018, increasing numbers of
scholars around the globe, especially in China and the United States,
have conducted relevant research in relation to DTs. Manufacturing and
construction are the most common application areas for DTs. Over the
past three years, the integration of AI, IoT, cloud, and digital
technologies has developed into a hotpot of research. Additionally,
communication technologies such as 5G and 6G contribute to the
development of DTs. In the future, it can be predicted that DTs will be
utilizing machine learning, blockchain and other technologies as a
result of advancements in becoming smarter and more secure over the
years.
Intrusion Detection Systems in High-Frequency Trading
Authors: Kannan Yamini
Published: March 2024

This paper explores the role of Intrusion Detection Systems
(IDS) in the context of High-Frequency Trading (HFT). Given the rapid,
automated nature of HFT, it’s crucial to have robust security measures
to promptly detect and address any malicious activities. IDS presents a
compelling solution by monitoring network traffic and detecting any
suspicious activities based on predefined rules. By considering various
types of IDS and their appropriateness for HFT environments, this paper
discusses effective implementation strategies and the impact of these
systems on HFT operations. We demonstrate through this discussion that
while incorporating IDS within HFT may present specific challenges, it
is a crucial component for the secure and efficient functioning of HFT
platforms.
Stable isotope analysis of the contribution of algae grazing fish, Ayu Plecoglossus altivelis, to the food source supply of macroinvertebrates

Published: March 2024

Attached algae are important primary producers in river ecosystems that
are foraged by benthic macroinvertebrates and grazing fishes. The ayu
Plecoglossus altivelis, which is an algae-feeding fish that feeds
on attached algae. Fine particulate organic matter (FPOM) is generated
when P. altivelis use their comb-like teeth to graze algae off
the surface of stones, and dislodge them into streams. Therefore, in the
present study, we investigated how P. altivelis feeding on algae
contributes to the production of algae-derived FPOM. We subsequently
evaluated the produced FPOM to determine whether it affected the origin
of the macroinvertebrate food supply. To investigate P. altivelis
density, the biomass of primary producers, and the food use fraction of
consumers, field surveys were conducted in the Kamo-gawa River, Japan,
in the summer season from 2018 to 2020. Carbon and nitrogen stable
isotope ratios of macroinvertebrates and food sources were measured to
estimate the composition of FPOM and the contribution of different food
sources to primary consumers. Our results showed that algal biomass
decreased at sites with a high density of P. altivelis, where the
proportion of algae-derived FPOM increased. The algal contribution to
macroinvertebrates increased at sites with high algae-derived FPOM.
Furthermore, structural equation modelling revealed that the feeding
behaviour of P. altivelis contributed to macroinvertebrate food
utilisation via the production of algae-derived FPOM. These results
suggest that P. altivelis is a keystone species that not only
produces algae-derived FPOM but also improves the food supply to
macroinvertebrates and promotes river ecosystem dynamics.
Test-retest Reliability of the Attention Network Test from the Perspective of Intrinsic Network Organization
Authors: Kong Ziwei , Chen Jingkai , Liu Jin , Zhou Yanfei , Duan Yuping , Li Hai , Yang Li-Zhuang
Published: March 2024

The attention network test (ANT), developed based on the triple-network
taxonomy by Posner and colleagues, has been widely used to examine the
efficacy of alerting, orienting, and executive control in clinical and
developmental neuroscience studies. Recent research suggests the
imperfect reliability of the behavioral ANT and its variants. However,
the classical ANT fMRI task’s test-retest reliability has received
little attention. Moreover, it remains ambiguous whether the
attention-related intrinsic network components, especially the dorsal
attention, ventral attention, and frontoparietal network, manifest
acceptable reliability. The present study approaches these issues by
utilizing an openly available ANT fMRI dataset for participants with
Parkinson’s disease and healthy elderly. The reproducibility of
group-level activations across sessions and participant groups and the
test-retest reliability at the individual level were examined at the
voxel, region, and network levels. The intrinsic network was defined
using the Yeo-Schaefer atlas. Our results reveal three critical facets:
(1) The overlapping of the group-level contrast map between sessions and
between participant groups was unsatisfactory; (2) The reliability of
alerting, orienting, and executive, defined as contrast between
conditions, was worse than estimates of specific conditions. (3) Dorsal
attention, ventral attention, visual, and somatomotor networks showed
acceptable reliability for the congruent and incongruent conditions. Our
results suggest that specific condition estimates might be used instead
of the contrast map for individual or group-difference studies.
Disturbance observer-based matrix-weighted consensus
Authors: Trinh Minh , Tran Quoc Van , Sun Zhiyong , Ahn Hyo-Sung
Published: March 2024

In this paper, we consider the matrix-weighted consensus problems with
disturbances. To this end, we firstly propose a new disturbance observer
design for systems with unknown matched or mismatched disturbances
representable as a linear combination of time-varying basis functions.
Under some assumptions on the boundedness and persistent excitation of
the regression matrix, the disturbances can be precisely estimated at an
exponential rate and thus, can be compensated by a suitable compensation
input. Next, disturbance-observer based consensus algorithms are
proposed for matrix-weighted networks of single- and double-integrators
with matched or mismatched disturbances. We show that both matched and
mismatched disturbances can be estimated and actively compensated, and
the system globally asymptotically converges to a fixed point in the
kernel of the matrix-weighted Laplacian. Depending on the network
connectivity, the system can asymptotically achieve a consensus or a
cluster configuration. The disturbance-observer based consensus design
is further extended for higher-order integrators with disturbances.
Finally, simulation results are provided to support the mathematical
analysis.
Space classification for indoor pedestrian navigation with morphological and functional characteristics
Authors: Tian Peng , Wang Yunjia , Wang Yong , Yang Yuan
Published: March 2024

Indoor navigation networks serve as the foundation for indoor pedestrian
navigation services. However, current graph-based topological network
models cannot easily represent complex indoor structures in a manner
consistent with user behaviour and cognitive patterns, and thus cannot
support fine-grained indoor navigation analysis services. To enhance the
rationality of the model, we considered the influences of morphological
and functional characteristics of indoor spaces on pedestrian movement
and proposed a method for classifying navigation spaces. This method,
based on convex space segmentation, defines morphological and functional
characteristic functions, classifying indoor navigation spaces as either
corridors or open spaces, which suitable for representing as median axis
models or visual graphs, respectively. These categories supported the
creation of topological network models for route planning analysis.
Indoor map experiments confirmed the effectiveness of our method in
identifying various types of corridors and open spaces, that addressing
the limitations of width-based parameters，even in complex indoor
settings.

Introduction: Doppler-derived pulmonary pulse transit time
(pPTT) is an auspicious hemodynamic marker in chronic pulmonary
diseases. The aim is to compare four distinct pPTT measurements and its
relation to right cardiac and pulmonary function. Methods:
Prospectively, 22 chronic obstructive pulmonary disease (COPD) patients
(one patient excluded) and 32 healthy subjects underwent repeated
distinct pPTT measurements, one standard echocardiography and pulmonary
function testing on the same day. pPTT was defined as the interval from
the R or Q-wave in the ECG to the corresponding pulse wave Doppler peak
late systolic (S2) or diastolic (D) pulmonary vein flow velocity (pPTT
R-S Q-S, R-D, Q-D). Reproducibility was evaluated
using Bland-Altman analysis, coefficient of variation (COV), intraclass
correlation coefficient (ICC) and power calculations. Coherence to right
ventricle RV tissue und pulse wave Doppler velocities (RV E´, RV S´, RV
A’, RV E, RV A, RV E/E‘, RV E/A (cm/s)), tricuspid annular plane
systolic excursion (TAPSE), forced expiratory volume in 1 second (FEV1),
vital capacity (FVC) predicted (%) and in (l) were analyzed.
Results: There was no significant difference and no bias
between pPTT measures (p range: 0.1 - 0.9). COV was in COPD 1.2 - 2.3%,
in healthy subjects 1.0 % - 3.1 %. ICC ranged from 0.92 (COPD) to 0.96
(healthy subjects). In COPD significant correlations were found for pPTT
R-S Q-S and R-D with RV E‘, (all >ρ:
0.49,

ρ: 0.49,

ρ: -0.39,

Conclusions: All pPTT measures were highly reproducible and affected by
diastolic RV performance. Defining Q as starting point seems clinically
advantageous considering electromechanical desynchrony in patients with
conduction disorders.
Parts of a whole: isotopic offset between single keratin-based tissues and whole-body values of birds and mammals
Authors: Davis Katherine , Zanden Hannah Vander
Published: March 2024

Abstract RATIONALE Stable isotope analysis is a frequently used
tool in ecology for unraveling dietary dynamics and trophic
relationships. In isotopic studies that use mixing models to infer diet,
a single tissue is often used to represent the isotopic values of a
whole organism. Here, we examine that assumption in keratin-based
tissues and provide recommendations for isotopic diet studies of animals
that consume prey whole. METHODS By comparing carbon ( δC) and nitrogen ( δN)
stable isotope values in single tissues of mammals and birds, this study
aims to elucidate the extent to which nondestructive sampling methods in
tissues such as hair and feathers, accurately represent the overall
isotopic composition of four mammalian species (rats, mice, rabbits,
guinea pigs) and one avian species (quail). RESULTS We found that
keratin-based tissue and the homogenized whole-body samples were
significantly different in δC values in
mammals (mean 𝚫 C -1.93 ± 0.37‰) but not in birds.
Feathers differed significantly from whole body in δN values in birds (mean 𝚫 N
-0.32 ± 0.11‰), but δN values did not differ
among hair and the whole body of mammals. CONCLUSIONS We provide a
mathematical correction for diet reconstruction based on specific
tissues, especially for animals consuming whole prey. We suggest that
future studies reconsider the assumption that non-invasively sampled
tissues are representative of whole-body isotopic values.
The observed spatiotemporal variability of Antarctic Winter Water
Authors: Spira Theo , Swart Sebastiaan , Giddy Isabelle S. , Plessis Marcel du
Published: March 2024

The Southern Ocean is central to the global overturning circulation.
South of the Antarctic Polar Front, Antarctic Winter Water (WW) forms in
the wintertime mixed layer below sea ice and becomes a subsurface layer
following summertime restratification of the mixed layer, overlaying
upwelled deep waters. Model simulations show that WW acts as a conduit
to seasonally transform upwelled deep waters into intermediate waters.
Yet, there remains little observational evidence of the distribution and
seasonal characteristics of WW. Using
18 years of in situ
observations, we show seasonal climatologies of WW thickness, depth,
core temperature and salinity. This study reveals, for the first time,
the distinct regionality and seasonality of WW. The seasonal cycle of WW
characteristics is tied to the annual sea ice evolution, whilst the
spatial distribution is impacted by the main topographic features in the
Southern Ocean driving an equatorward flux of WW. Through the
identification of these localized northward export regions of WW, this
study provides further evidence suggesting an alternative view from the
conventional ‘zonal mean’ perspective of the overturning circulation. We
show that specific overturning pathways connecting the subpolar ocean to
the global ocean can be explained by ocean-topography interactions.

Environmentally friendly and economically viable methods are essential in the selection of materials and techniques for the synthesis of nano-zero-valent iron. Plants, with their high polyphenol content and antioxidant capacity, have found application in eco-friendly synthesis processes. The definitive screening design (DSD) monitored four key process parameters for the concurrent removal of copper and phosphate: copper concentration (ranging from 1 to 9 mg L-1), phosphate concentration (ranging from 1 to 9 mg L-1), initial pH values (ranging from 2 to 10), and the dosage of nano-zero-valent iron (ranging from 2 to 16 mL). The analysis results provide valuable insights into the significant individual factors influencing the process, along with the potential for their interactions. The model also proposes process optimization to attain maximum removal efficiency, and subsequent verification confirmed its superiority among the alternatives. Mechanisms such as sorption, reduction, complexation, electrostatic attraction, and ligand exchange play pivotal roles in the effective removal of copper and phosphate using nano-zero-valent iron. In summary, this research yields several benefits: the utilization of environmentally sustainable materials, a substantial reduction in experimental complexity, coupled with the ease of the entire procedure, simultaneous and highly efficient copper and phosphate removal, favorable pH levels and, notably, no requirement for additional treatment.

Published: March 2024

Screening mammography is an imaging procedure which allows breast cancer detection in its early stage. The Breast Imaging and Reporting Data System (BI-RADS) determined six radiological categories for describing lesions. The core needle biopsy (CNB) is minimally invasive procedure that provides pathohistological samples. Via microscopic analysis, samples are categorized into five groups according to the B system for pathohistological report. The aim of the study was to follow the spectrum of pathohistological diagnoses; to define which BI-RADS and core categories are most commonly expressed in certain age groups; and to determine the incidence of histological diagnoses in different BI-RADS categories. The study included 631 patients and data was analysed in order to localise the lesion, BI-RADS and core category and pathohistological diagnosis. Within 631 biopsies, 33 diagnoses were given. In each age group, the findings indicating a high risk for malignancy were the most common (>2 %). The highest percentage of malignant categories was found in patients over the age of 61. Final diagnoses showed a deviation compared to the radiological categories, especially in BI-RADS4 category. Pathohistological diagnosis is always a definite confirmation of a breast lesion type and it has significant contribution to the evaluation of CNB quality.

Published: March 2024

Experiencing rapid development and growth, cities worldwide face a surge in air pollution, primarily driven by the increased concentrations of the particulate matter (PM) originating from various anthropogenic sources, such as traffic, household fuel combustion, and industrial and construction activities. Urban green spaces can naturally filter PM through physicochemical processes, serving as effective urban planning instruments for the improvement of the air quality. Focusing on a street in Novi Sad, the second-largest city in Serbia, this study investigates the efficiency of vegetation in mitigating air pollution, specifically PM10 emissions from traffic and construction activities. Using the contemporary monitoring and modelling techniques for measuring and predicting PM10 concentrations, the focus of this research is to evaluate the efficacy of vegetation in affecting and minimizing detected PM concentrations. The results indicate a significant reduction in the monitored PM10 concentrations behind the green barrier compared to the modelled concentrations near the pollution source (on the road) for both traffic and construction-related emissions. The paper highlights the capacity of green elements to act as natural air pollution mitigators and suggests better integration of strategic environmental management into urban planning to foster the development of healthier and more sustainable cities, providing recommendations to facilitate this objective.
Analyzing Depreciation: A Financial Accounting Data Analytics and Visualization Case
Authors: Samuels Janet A. , Snow Mason C.
Published: March 2024

This case uses a financial accounting context to help instructors incorporate data analytics in the accounting curriculum. The case’s flexible design allows it to be used in a data analytics or financial accounting course for instructors with little to no data analytics experience. For an analytics course, students extract, transform, and load fixed asset and depreciation data from a company’s five sites. Students will then validate the accuracy and completeness of the data by creating visualizations. The case can be accomplished using any data analytics tool; Teaching Notes are presented using Power BI. The case and Teaching Notes include modifications for a financial accounting course where students are given data visualizations to identify depreciation anomalies (where no analytics software is required). An extension for audit courses is also discussed. The case serves to develop students’ analytics skills while simultaneously reinforcing their understanding of depreciation concepts.
Do Short Sellers Target Firms with High Climate Risks? International Evidence
Authors: Jiang Haiyan , Luo Le
Published: March 2024

Using an international sample of firms from 36 countries over the period 2002 to 2018, we investigate whether short sellers take firms’ climate risk into consideration when making investment decisions. Our empirical results show that short sellers increase their short-selling interest in firms with high carbon emission intensity but shun good carbon performers. Furthermore, the effect of climate risk on short-selling interest is more pronounced for firms operating in countries or regions that have adopted an emission trading scheme (ETS) as well as in countries characterized by higher regulatory quality and greater media pressure. We also document that short sellers in countries with stringent carbon regulations, higher environmental awareness, and superior environmental performance are more sensitive to climate risk. Our channel analyses highlight that stock overvaluation and an opaque information environment are two potential motives for short-selling interest in carbon-risky firms.
The Interposed Smudge-Kaposiform Haemangioendothelioma
Authors: A Bajaj
Published: March 2024

Kaposiform hemangioendothelioma emerges as an exceptionally discerned endothelial cell neoplasm. Commonly, tumefaction disseminates within entire dermis with expansion into the subcutaneous tissue and exhibits localized tumour aggressiveness. Characteristically, proliferation of spindle shaped endothelial cells is commingled with lymphatic vessels demonstrating capillary haemangioma-like articulations. Glomeruloid structures are configured of discrete capillary lobules demonstrating a swirling pattern. Nodules of spindle shaped endothelial cells are encompassed by peripheral lymphatic vessels articulating lymphangioma-like areas. Tufted angioma configures as a benign, superficial, vascular neoplasm arising as a congenital lesion or appears within infants and paediatric population. The aggressive neoplasm is associated with enhanced morbidity and may undergo spontaneous retrogression, in contrast to Kaposiform hemangioendothelioma.
