Authors: Kour Jagneet , Bhatia Raino
Published: November 2024

The importance of emotionally intelligent leadership is paramount in this age of accelerating technological innovation and transforming interpersonal relationships. Emotionally Intelligent (EI) leadership is different from conventional management in that it promotes healthier working conditions and leads to more noteworthy achievements by centring on the growth of self-awareness, empathy, and interpersonal skills. The outcomes of emotionally intelligent leadership on organisational culture are addressed in this chapter along with its guiding principles. Despite traditional theories, which frequently fail to account for the humanistic components of workplace dynamics, EI leadership takes these into perspective. This chapter sheds light on how leaders can improve their performance and have a positive impact in organisational settings by emphasising tactics for developing emotional intelligence. The impact on organisational climate, the ability of EI to transform leadership, and the function of EI in developing interpersonal and intrapersonal capacities are important themes.
Towards a unified approach to sciences and the arts
Authors: Fokas Athanassios S.
Published: November 2024

The process of ‘comprehending how we comprehend’, requires elucidating fundamental cognitive mechanisms used by the brain. In these regards, this article discusses two basic hypotheses. First, unconscious and conscious processes form a continuum. Second, humans have a predisposition to construct real versions of mental images and of unconscious structures, as well as to assign to them specific symbols. In addition, it is claimed that our process of comprehending is aided by invoking certain concepts which are important because, apparently, they reflect fundamental cognitive mechanisms. Among them are the notions of continuity, associations, abstraction, reduction, unification, and generalization, as well as the dialectic pairs of local versus global processes and simplicity versus complexity.

Authors: Kodom Ruby V. , Netangaheni Robert T.
Published: November 2024

Background: Rising cases of non-communicable diseases (NCDs), poor health choices, mistrust of the health system, self-medication, resistance of diseases to medication and dissatisfaction with the service experience serve as red flags on the path to Universal Health Coverage (UHC).Aim: This study explored the importance of patient-centred care (PCC) and patient empowerment (PE) within the context of healthcare service delivery in Ghana.Setting: The study considered PCC and PE from the perspective of three public healthcare facilities within the Greater Accra region.Methods: The researcher adopted a qualitative exploratory research approach. The study employed purposive sampling for the selection of healthcare facilities and healthcare providers. Convenience sampling was applied to select patient participants. A total of 33 in-depth interviews and 4 focus group discussions (FGDs) were conducted across the three sampled facilities as part of the data collection process.Results: Healthcare providers and patients unanimously view quality as essential for effective healthcare delivery. The application of the capacitating role of PE and PCC is inexact and largely left to subjective interpretation.Conclusion: The Ministry of Health (MOH) has recognised that patient experiences, a key indicator of care quality, have often been suboptimal and is actively working to address these weaknesses.Contribution: This study supports the call for health systems to remain committed to efforts to achieve UHC, with a focus on PCC and PE.

Published: November 2024

Background: Acute myeloid leukaemia (AML) is a heterogeneous group of myeloid neoplasms for which two international classification systems exist: the 2022 World Health Organization (WHO) and international consensus classification of myeloid neoplasms (ICC), with an emphasis on molecular abnormalities.Aim: To determine the molecular-genetic profile of AML in the South African public sector.Setting: The Charlotte Maxeke Johannesburg Academic Hospital, Somatic Cell Genetics Unit, National Health Laboratory Service, South Africa.Methods: All newly diagnosed AML cases analysed with next generation sequencing (NGS) between January 2019 and December 2022 were retrospectively reviewed. Clinical and laboratory data were obtained from the laboratory information system.Results: In total, 194 AML cases were tested by NGS (162 classifiable), with a median age of 42 years for adults and 7 years for the paediatric cohort. There were 21 cases of AML with mutated TP53 (ICC), 5 of which were unclassifiable with the WHO classification system. In t(8;21) (q22;q22.1), KIT and FLT3-ITD mutations were present in 43% and 20% of cases respectively; FLT3-ITD in 50% of acute promyelocytic leukaemia (APL) and ~20% of AML with NPM1 were triple mutated (NPM1, DNMT3A, FLT3-ITD).Conclusion: This study revealed a high proportion of exon 17 KIT mutations in t(8;21), FLT3-ITD mutations in APL and triple mutated AML with mutated NPM1, all of which are likely to be driving the poor outcomes seen in these AML subgroups in our setting.Contribution: This is the first nationwide description of the molecular-genetic landscape of AML in the South African public sector.

Authors: Schoeman Renata , Lai Evelyn Y. , Nel Anne-Marie , Gani Mashra , Fulat Muhammed A. , Mahomed Akbar A.
Published: November 2024

Background: Attention deficit hyperactive disorder (ADHD) is a neurodevelopmental disorder occurring in children and adults. Pharmacotherapy remains the cornerstone of ADHD treatment. Stimulants such as methylphenidate are effective and have been one of the best studied and most frequently used treatment for ADHD. However, different delivery mechanisms and devices may potentially impact patient experience and real-life outcomes.Aim: This study evaluated the effectiveness of Multiple-Unit Pellet System Delivered Extended-Release Methylphenidate (Contramyl XR) on symptom control and reported outcomes in ADHD patients, in a real-world setting.Setting: A phase IV, open label, flexible dose, prospective, observational study conducted at six sites covering five provinces of South Africa.Methods: About 119 participants with ADHD (both newly diagnosed [treatment-naïve] and methylphenidate-treated [switch-over] patients) were enrolled and initiated either on Contramyl XR or switched over from methylphenidate to Contramyl XR. Primary efficacy was assessed by Weiss Functional Impairment Rating Scale (WFIRS) over 12 weeks.Results: In all, 117 participants completed the study (treatment-naïve patients: 46% [n = 55] and switch-over patients: 54% [n = 64]). Mean change from baseline in total WFIRS (95% confidence interval) was –17.7 (–21.1, –14.3; p  0.001) at week 4 and –29.3 (–33.5, –25.2; p  0.001) at week 12. At week 12, there was significant improvement in WFIRS scores, with treatment satisfaction reported by treatment-naïve patients. Switch-over patients also demonstrated comparable effectiveness.Conclusion: Contramyl XR was found to be clinically effective either as de novo or as switch therapy. It was well tolerated, and all patients chose to continue with the treatment option.Contribution: Despite distinct and different delivery mechanism of Contramyl XR, this study provides evidence for using it as an alternate treatment option versus reference methylphenidate, in both treatment-naïve and switch-over ADHD patients. Study participants willingness to continue Contramyl XR therapy post study, further strengthens the confidence on the effectiveness of Contramyl XR in managing ADHD patients.

Authors: Acharya Suchi , Deepthi Alluri , Kumar Manish
Published: November 2024

Background:

Situs inversus (SI) totalis is a rare congenital anomaly characterized by complete inversion of abdominal and thoracic visceral organs. While renal abnormalities have been documented in such cases, the association with nephrotic syndrome (NS) is exceptionally rare.

Clinical Description:

A 2.5-year-old girl, diagnosed with NS, a year ago, presented with anasarca due to relapse. Routine clinical examination showed normal vital parameters, anthropometry, mild pallor, and pitting edema. While abdominal examination revealed ascites, cardiovascular examination was suggestive of dextrocardia which was confirmed by echocardiogram without structural heart defects. Ultrasound abdomen liver, spleen, and stomach showed lateral inversion. Laboratory investigations were consistent with a relapse of NS.

Management and Outcome:

The child was managed with corticosteroids along with anti-edema measures, resulting in remission.

Conclusion:

This case brings out the exceptional rarity of SI totalis coexisting with NS and encourages further research into potential genetic and immunological factors which may explain this coexistence.

Authors: Priyamvada Richa , Ranjan Rupesh , Chaudhury Suprakash , Patil Jaideep
Published: November 2024

Background:

Motivational enhancement therapy (MET) is a client-centered approach that guides individuals in recognizing and resolving their uncertainties about making personal changes, and having self-efficacy is crucial as it acts as a safeguard against relapses. Personality traits and locus of control are identified as significant factors in the realm of drug addiction and misuse, which further affects treatment and relapse.

Aim:

To study the efficacy of MET on the self-efficacy and locus of control of patients with alcohol dependence.

Materials and Methods:

A sample of 30 patients with alcohol dependence fulfilling the ICD-10 criteria were selected from the Department of Psychiatry of a tertiary care hospital attached to a medical college and a private clinic in Bhopal, MP, for the study. The age range of the sample was 25–45 years based on the purposive sampling method. The study was pre- and post-intervention. Initially, a socio-demographic data sheet was filled to know the self-efficacy, and Locus of Control Scales were administered. After pre-assessment, MET sessions were introduced to the patients. A total of 15 sessions were taken within 3 months of follow-up, and after follow-up, an assessment was conducted to see the outcome of MET sessions.

Results:

The result shows improvement in self-efficacy and change in locus of control after the MET sessions.

Conclusion:

MET is effective in decreasing ambivalence and hence improving the self-efficacy of the patient, which may prevent the patient from relapse.
Comparative Study of Pancreatic Head and Body Size in Diabetic and Nondiabetic Individuals Age Group >65 Years by USG
Authors: Sisodiya Hiranshi , Barjatya Ranjana , Bali Mannhit Kaur , Patnaik Kakoli
Published: November 2024

Background and Objectives:

Diabetes mellitus is the collective term for disorders affecting glucose homeostasis. The pancreas is situated in the retroperitoneum within the anterior pararenal fascial space and positioned anteriorly to the aorta and inferior vena cava. Specifically, the pancreas is commonly located just below the origin of the superior mesenteric artery. Ultrasound imaging serves as a valuable tool for acquiring detailed information about the pancreas, encompassing factors such as pancreatic size, echotexture, ductal anatomy, and the surrounding structures. This imaging modality not only facilitates diagnostic evaluations but also allows for interventional procedures, all accomplished efficiently within a brief time frame and at a minimal cost.

Subjects and Methods:

One hundred and fifty healthy adults as controls and 150 diabetic patients of the same age group >65 years of age group were evaluated by ultrasound sonography.

Results:

The mean pancreatic head and body is 2.01 ± 0.38 cm and 1.26 ± 0.18 cm, respectively, in diabetic participants, whereas in controls, it is 2.40 ± 0.13 cm and 1.59 ± 0.17 cm. This showed a significant decrease in pancreatic head and body size in diabetic individuals.

Interpretation and Conclusions:

Diabetic individuals exhibit smaller pancreatic head and body compared to normal controls.
High-Order Local Clustering on Hypergraphs
Authors: Wei Jingtian , Yang Zhengyi , Luo Qi , Zhang Yu , Qin Lu , Zhang Wenjie
Published: November 2024

Graphs are a commonly used model in data mining to represent complex relationships, with nodes representing entities and edges representing relationships. However, graphs have limitations in modeling high-order relationships. In contrast, hypergraphs offer a more versatile representation, allowing edges to join any number of nodes. This capability empowers hypergraphs to model multiple relationships and capture high-order information present in real-world applications. We focus on the problem of local clustering in hypergraphs, which computes a cluster near a given seed node. Although extensively explored in the context of graphs, this problem has received less attention for hypergraphs. Current methods often directly extend graph-based local clustering to hypergraphs, overlooking their inherent high-order features and resulting in low-quality local clusters. To address this, we propose an effective hypergraph local clustering model. This model introduces a novel conductance measurement that leverages the high-order properties of hypergraphs to assess cluster quality. Based on this new definition of hypergraph conductance, we propose a greedy algorithm to find local clusters in real time. Experimental evaluations and case studies on real-world datasets demonstrate the effectiveness of the proposed methods.

Comprehensive Characterization of Soft Tissue and Surrogate Materials
across Varied Loading Methods
Authors: Dennis Cole J. , Quenneville Cheryl E.
Published: November 2024

Exploring the mechanical properties of soft tissues under compressive loading is
crucial for understanding their role in automobile incidents. Soft tissues,
which serve as cushions or padding between bone and vehicle interiors,
significantly influence contact duration and forces, thereby altering incident
kinematics and injury. In this investigation, muscle and soft connective tissues
from post-mortem human subjects (PMHS) forearms were excised and subjected to
compression and indentation testing methods at various rates and strains.
Specific samples with higher proportions of muscle were compared against samples
without muscle tissues to evaluate the role of compositional changes.
Anthropomorphic test device (ATD) upper extremity foam and vinyl–foam composite
analog tissues underwent similar testing for comparison. High impact rates
simulating those in high-speed automotive collisions were achieved using a
custom-built drop tower impactor setup. The results revealed significantly
higher stiffness values for samples with large proportions of muscle tissue
compared to no muscle samples at smaller deformations. Substantial differences
in stiffness were seen between soft tissues and ATD materials across most
loading rates and strains, although some exceptions were noted at higher rates
and strains. An indentation and modified Zener model were used to quantify
material parameters. These findings provide a solid basis for advancing ATD
analogs and have broader implications for soft tissue research. Moreover, this
work represents a crucial step toward enhancing safety standards in the
automotive industry.

Published: November 2024

Thorax injuries are a significant cause of mortality in automotive crashes, with
varying susceptibility across sex and age demographics. Finite element (FE)
human body models (HBMs) offer the potential for injury outcome analysis by
incorporating anthropometric variations. Recent advancements in material
constitutive models, cortical bone fracture and continuum damage mechanics model
(CFraC) and an orthotropic trabecular bone model (OrthoT), offer the opportunity
to further improve rib models. In this study, the CFraC and OrthoT material
modes, coupled with age-specific material properties, were progressively
implemented to the Global Human Body Model Consortium small female 6th rib. Four
distinct 6th rib models were developed and compared against sex and age-specific
experimental data. The updated material models notably refined the predictions
of force–displacement responses, aligning them more closely with the
experimental averages. The CFraC model significantly improved the prediction of
displacement at fracture, suggesting that incorporating stress triaxiality
criteria can better account for the complex loading conditions ribs face in
crashes, such as combined cortical tension and shear due to rib bending and
torque. The study highlights the importance of using biofidelic material models
and sex and age-specific data to simulate hard tissue fractures. The improved
rib model demonstrates the effectiveness of integrating updated material
properties and constitutive models to enhance injury prediction accuracy, which
can inform better automotive safety designs and reduce mortality rates. Further
research is recommended to extend these models across different demographic
groups to fully capture population variability in rib fracture risk.
Determination of Postmortem Human Subject Response to Vertical Drop
Tower Testing and Initial Application for Total Human Model for Safety Finite
Element Model Validation
Authors: DeWitt Timothy R. , Marcallini Angelo M. , Bolte IV John H. , Kang Yun-Seok
Published: November 2024

Drop tower testing was conducted using 50th percentile male PMHS at 15G peak
acceleration in a rigid seat, with a seat pan-to-seatback angle of 90°. Subjects
were instrumented with 6DOF motion blocks at T1, T4, T12, L3, and S1 to capture
detailed vertebral body kinematics. Pressure sensors were also placed throughout
the lumbar spine to estimate force in the intervertebral discs from S1-L2. PMHS
were restrained using a pilot torso harness attached to the seat at the
shoulders and lap belt, both pretensioned to 89 N. Reaction forces were measured
in the seat using six-axis loads under the seat pan. Final positioning of the
occupant was documented using a FARO arm point probe and laser scanner. To
recreate the experimental setup, CAD models of the experimental fixture were
meshed using a commercial FE modeling software (Hypermesh) and imported into
LS-Dyna for incorporation with the THUMS model. The belt routing tool in
LS-PrePost v4.9.12 was used to develop the torso harness and shoulder and lap
belts. Pre-simulation was performed to position the THUMS model in accordance
with recorded FARO data, and the experimentally recorded seat vertical
acceleration was assigned using Boundary_Prescribed_Motion. Finally,
instrumentation locations were duplicated within the THUMS model to match the
PMHS experimental setup. The THUMS model showed similar head kinematics compared
to the experiment, which went first into extension, followed by flexion during
the primary pulse. The torso of the model, however, experienced an increased
flexion/compression response compared to PMHS. The peak reaction force in the
simulated seat load cells measured 12.7 kN, which was within one standard
deviation of the average normalized experimental values (average = 12.8 kN,
standard deviation = 0.4 kN). The average load in the lumbar spine in the model
was found to be 3.3 kN, which was lower than PMHS average by more than two
standard deviations.

Published: November 2024

Pelvic orientation in vehicles is crucial for preventing injuries and creating
safer vehicles and restraint systems. A better understanding of pelvic
orientation could provide more accurate anthropomorphic test device (ATD) models
of underrepresented populations such as obese individuals, children, and small
females. Sonomicrometry is the use of piezoelectric transducers that transmit
ultrasound signals to each other to measure the distance between them. These
signals may be aggregated using triangulation. In this experiment, ultrasound
crystals were secured to the surface of a porcine surrogate to evaluate pelvic
movement. This data was then processed using Sonometrics software to generate a
3D model of four static positions and three dynamic tests. The test was
validated using a camera and a 3D measurement arm (CMM) to validate XYZ
positions. This article discusses how this method could be helpful for
developing more accurate ATD models, preventing fatalities in vehicle
crashes.

Impact Kinematics
Authors: Stark Nicole E.-P. , Calis Andrew , Wood Matthew , Piwowarski Summer Blue , Dingelstedt Kristin , Begonia Mark , Rowson Steve
Published: November 2024

Head injuries account for 15% of snowsport-related injuries, and the majority of
head impacts occur against ice or snow, low-friction surfaces. Therefore, this
study aimed to evaluate how surface friction affects snowsport helmets’ oblique
impact kinematics. Ten helmet models were impacted using an oblique drop tower
with a 45-degree anvil and NOCSAE headform, at three locations, two surface
friction conditions, and a drop speed of 5.0 m/s. Our findings indicate that
friction affects peak linear acceleration, peak rotational acceleration, and
peak rotational velocity during helmet impacts, with changes in post-impact
rotation and impact response varying by location. Surface friction affects head
impact kinematics, underscoring the need for sport-specific lab testing and
emphasizing the need for friction-specific and sport-specific testing,
particularly for snowsports, where surface conditions like snow and ice can
alter kinematics.

Authors: Li Wei , Zhou Hanyun , Shi Jiekai , Cheng Weinan , Wang Fang , Bai Jie
Published: November 2024

With the rapid advancement of Unmanned Aerial Vehicle (UAV) technology, their
assigned missions have become significantly more intricate. Individual UAVs are
no longer sufficient to meet these diverse and demanding requirements. There is
now a shift towards employing multiple UAVs operating collaboratively to address
complex tasks, replacing the reliance on singular units. This study focuses on
the complexities of coordinated flight within UAV formations. A dynamic
consensus optimal control algorithm is proposed for distributed formations,
grounded in optimal control theory. Furthermore, the enhanced control method is
validated via simulation on a semi-physical visualization platform, effectively
closing the gap between real-world formation requirements and simulation
outcomes. The results from these simulations underscore that the proposed method
effectively preserves UAV formation integrity and demonstrates exceptional
applicability in real-world scenarios.

Published: November 2024

As a novel passive control method, the acoustic black hole (ABH) structure
demonstrates achieve energy aggregation efficiently and has the characteristics
of lightweight and wide-band noise reduction. This study applies ABH theory to
aircraft ducts by incorporating an additional ABH structure into the inner wall
design. The spiral structure is specifically engineered to increase the
characteristic length of the black hole and lower the cutoff frequency. To
validate the effectiveness of this ABH structural design, finite element
analysis was conducted to investigate structural frequency response, acoustic
energy concentration characteristics, as well as damping and energy dissipation
effects. Simulation results indicate significant energy accumulation on the
inner wall with ABH structure in frequencies above 800Hz. Additionally, through
acoustic-structure coupling analysis, far-field acoustic radiation
characteristics were determined for this structural design followed by a
comprehensive summary analysis.

Authors: Yanan Li , Li Haiwang , Xie Gang , Sun Mohan
Published: November 2024

The fixed-wing VTOL is a new type of aircraft that combines the advantages of
multi-rotor and fixed-wing aircraft. Enable freely taking off and landing, while
maintaining high flight speeds during cruising. However, higher requirements for
the powertrain system have emerged. The powertrain needs to adapt to the layout
of distributed propulsion devices while also ensuring sufficient endurance. Both
the full-electric powertrain and traditional fuel-based powertrain are unable to
meet this demand, making the hybrid-electric powertrain one of the most feasible
solutions currently available. A 10kW level hybrid-electric powertrain system
was designed for a fixed-wing VTOL aircraft. The power generation performance
tests are conducted to analyze the coupling working characteristics of the
engine and generator. The performance of the hybrid configuration and the
full-electric configuration in terms of power-to-weight ratio, energy-to-weight
ratio, and endurance are compared. The results indicate that the payload
capacity of the hybrid-electric system under the same range has increased by
52%, and the energy-to-weight ratio has improved by 16%, extending the endurance
of the flight platform from 51min to 67min. The findings demonstrate that the
hybrid-electric system can expand the performance capabilities of the aircraft
to fulfill a wider range of mission requirements.
Trajectory Tracking Control for a Hexacopter UAV: A
Constraint-Following Approach Guaranteeing Prescribed
Performance
Authors: Wang Ningning , Li Xiang , Yin Hui
Published: November 2024

The development of low-altitude economy driven by aircraft has garnered
significant attention from both academia and industry. The hexacopter unmanned
aerial vehicle (UAV) is an important component of low-altitude aircraft.
Although it has not been as widely used as the quadcopter UAV, the greater
delivery capacity and enhanced fault tolerance sustain its promising development
prospects. However, the trajectory tracking control, a fundamental task of
hexacopter UAV, remains challenging if the control algorithm is required to work
on the dynamics level with theoretical performance guarantees, since its
position control has to be realized by its attitude control. This study proposes
a novel trajectory tracking control with prescribed performance for the
hexacopter UAV that works on the dynamic model. The proposed approach is
established by a dual-loop constraint-following control with the
state-transformation technique, where equality and inequality constraints are
used to describe the tracking task and the prescribed performance, respectively.
The effectiveness of the proposed control is endorsed by rigorous theoretical
analysis and simulations.

Airspace

Published: November 2024

Navigating Unmanned Aerial Vehicles (UAVs) in urban airspace poses significant
challenges for fast and efficient path planning due to the environment's
complexity and dynamism. However, the existing research on UAV path planning has
ignored the speed of algorithmic convergence and the smoothness of the generated
path, which are critical for adapting to the dynamic changing of the urban
airspace as well as for the safety of ground personnel, and the UAV itself. In
this study, we propose an enhanced Ant Colony Optimization (ACO) algorithm that
incorporates two heuristic functions: the compass heuristic and the inertia
heuristic. These functions guide the ant agents in their movement towards the
destination, aiming for faster convergence and smoother trajectories. The
algorithm is evaluated using a gray-scale lattice map generated from ground
personnel risk data in Suzhou City. The results indicate that the improved ACO
path planning algorithm demonstrates both efficiency and quality, converging
faster than traditional ACO methods in a gray-scale lattice map and producing
smoother paths for UAV navigation.

Structural Parameterizations of the Biclique-Free Vertex Deletion Problem
Authors: Goldmann Lito , Kellerhals Leon , Koana Tomohiro
Published: November 2024

In this work, we study the Biclique-Free Vertex Deletion problem: Given a
graph $G$ and integers $k$ and $i \le j$, find a set of at most $k$ vertices
that intersects every (not necessarily induced) biclique $K_{i, j}$ in $G$.
This is a natural generalization of the Bounded-Degree Deletion problem,
wherein one asks whether there is a set of at most $k$ vertices whose deletion
results in a graph of a given maximum degree $r$. The two problems coincide
when $i = 1$ and $j = r + 1$. We show that Biclique-Free Vertex Deletion is
fixed-parameter tractable with respect to $k + d$ for the degeneracy $d$ by
developing a $2^{O(d k^2)} \cdot n^{O(1)}$-time algorithm. We also show that it
can be solved in $2^{O(f k)} \cdot n^{O(1)}$ time for the feedback vertex
number $f$ when $i \ge 2$. In contrast, we find that it is W[1]-hard for the
treedepth for any integer $i \ge 1$. Finally, we show that Biclique-Free Vertex
Deletion has a polynomial kernel for every $i \ge 1$ when parameterized by the
feedback edge number. Previously, for this parameter, its fixed-parameter
tractability for $i = 1$ was known (Betzler et al., 2012) but the existence of
polynomial kernel was open.
On $[1,2]$-Domination in Interval and Circle Graphs

A subset $S$ of vertices in a graph $G=(V, E)$ is a Dominating Set if each
vertex in $V(G)\setminus S$ is adjacent to at least one vertex in $S$. Chellali
et al. in 2013, by restricting the number of neighbors in $S$ of a vertex
outside $S$, introduced the concept of $[1,j]$-dominating set. A set $D
\subseteq V$ of a graph $G = (V, E)$ is called a $[1,j]$-Dominating Set of $G$
if every vertex not in $D$ has at least one neighbor and at most $j$ neighbors
in $D$. The Minimum $[1,j]$-Domination problem is the problem of finding the
minimum $[1,j]$-dominating set $D$. Given a positive integer $k$ and a graph $G
= (V, E)$, the $[1,j]$-Domination Decision problem is to decide whether $G$ has
a $[1,j]$-dominating set of cardinality at most $k$. A polynomial-time
algorithm was obtained in split graphs for a constant $j$ in contrast to the
Dominating Set problem which is NP-hard for split graphs. This result motivates
us to investigate the effect of restriction $j$ on the complexity of
$[1,j]$-domination problem on various classes of graphs. Although for $j\geq
3$, it has been proved that the minimum of classical domination is equal to
minimum $[1,j]$-domination in interval graphs, the complexity of finding the
minimum $[1,2]$-domination in interval graphs is still outstanding. In this
paper, we propose a polynomial-time algorithm for computing a minimum
$[1,2]$-dominating set on interval graphs by a dynamic programming technique.
Next, on the negative side, we show that the minimum $[1,2]$-dominating set
problem on circle graphs is $NP$-complete.

The paper presents a monitoring activity of the Freshwater fish (Carassius gibelio) samples consumed in Olt River, Romania. A monitoring study lasting 9 years (2014-2022) was realized. Two sampling points for the Olt River were chosen, the first one upstream of the discharge point of the magistrate channel “Deversor Olt” (background location) and respectively the second sampling point downstream of the liquid effluents discharge point (indicator location). A maximum activity concentration for40K of 95.75 Bq∙kg-1 fw, is observed. The activity of interest radionuclides (7Be, 51Cr, 60Co, 137Cs, 226Ra, 235U) is below the detection limit. The method used was high resolution gamma ray spectrometry performed with an HPGe detector. It was observed that the values recorded for the background location had a slight difference compared with the values recorded in the indicator locations. The nuclear activity in the pre-operational stage of the Experimental Pilot Plant for Tritium and Deuterium Separation did not have any impact on the environment so far. This study creates a unique database that could be relevant for further Operational Program for Environmental Monitoring of the Experimental Pilot Plant and other economical agents in the area.

Introduction. Diffusion tensor imaging (DTI) is a technique that allows evaluating diffusion of water molecules along the myelin sheath of nerve fibers and obtaining information about the integrity of brain and spinal cord pathways. Obtaining reproducible values of diffusion parameters is an urgent and feasible task. The aim of this study was to establish the values of DTI parameters along the entire length of the spinal cord in healthy children for further use in the assessment of acute injury, its consequences and other spinal cord diseases.
Materials and methods. The study included fifteen healthy patients of 13 to 18 years, including 6 girls and 8 boys, average age was 15.2 ± 1.2 years. The study was performed on a Philips Achieva dStream 3T MRI scanner (Netherlands). As part of this study, a spine MRI protocol was developed to cover the entire volume of spinal cord with separate visualization of cervical and thoracic spine (duration: 9 min 48 sec). The IRIS ZOOM sequence (Philips) was used to obtain DTI images. Spinal Cord Toolbox software package was used to process the data. Statistical analysis was performed using GraphPad Prism software, and significance was determined at p < 0.05.
Results. Mapping and calculation of the following diffusion parameters: fractional anisotropy (FA), medial (MD), longitudinal or axial (AD) and transverse (RD) diffusion showed the average values of the parameters FA, AD, MD, RD of the spinal cord of children to be: FA, AD, MD, RD of spinal cord were: FA = 0.63 ± 0.06, AD = 2.1 ± 0.3 × 10−3 mm2/s, MD = 1.15 ± 0.16 × 10−3 mm2/s,
RD = 0.68 ± 0.12 × 10−3 mm2/s. An increase in FA was detected at the Th2–Th9 level compared to the values at the C6–Th1 and Th10–Th12 levels. The AD coefficient at the Th2–Th9 level is increased relative to the C2–C5 and C6–Th1 levels. MD values in spinal cord areas at the Th2–Th9 and Th10–Th12 levels are statistically higher relative to higher levels of the spinal cord. RD values in the zone at the Th10–Th12 level are increased relative to all other areas.
Conclusion. The study established the diffusion indices of FA, MD, AD, RD of spinal cord in children aged 12 to 18 years and showed small differences between the spinal cord regions. The data obtained can be used as reference values for assessing spinal cord condition in various pathological processes (trauma, demyelinating and tumor diseases) in children for the corresponding age group.
La evaluación de la constitucionalidad del impuesto a las ganancias extraordinarias de las instituciones financieras: Un análisis en base al Art. 18 de la Ley Orgánica para enfrentar el conflicto armado interno, la crisis social y económica
Authors: Calle Granja José Hernán , Trelles Vicuña Diego Fernando

El presente artículo aborda la evaluación de la constitucionalidad del Impuesto a las Ganancias Extraordinarias de las Instituciones Financieras, establecida en el Artículo 18 de la Ley Orgánica para Enfrentar el Conflicto Armado Interno, la Crisis Social y Económica. El objetivo principal es determinar la viabilidad constitucional de dicho impuesto. Para ello, se empleó una metodología mixta, combinando un enfoque cuantitativo, a través de una encuesta, y un enfoque cualitativo, mediante el análisis de diversas fuentes bibliográficas y doctrinarias. Los resultados demostraron una aceptación moderada del impuesto, aunque con divisiones de opinión respecto a su justificación y posible vulneración de principios constitucionales, como capacidad contributiva, no confiscatoriedad e igualdad. Las conclusiones señalan que, si bien los impuestos extraordinarios pueden estar justificados en situaciones excepcionales, el Impuesto a las Ganancias Extraordinarias presenta cuestionamientos desde el punto de vista constitucional, al poder vulnerar dichos principios fundamentales en materia tributaria. Por lo tanto, existe la posibilidad de que este impuesto sea considerado inconstitucional.
