Abstract: Surveillance videos have become crucial objects for ensuring the safety and security of crowded places such as concerts, subways, airports, and many others. In recent times, the installation of security cameras has rapidly increased in both public and private places. The complexity of finding the anomaly will increase drastically as the amount of footage increases and there may be occlusions for the analysis of the video, which consumes both time and may result in false detections. To overcome these drawbacks, we have produced an approach using machine learning algorithms. In this approach, we use the background subtractor for the elimination of the static things in the video frames and concentrate on the dynamic things. Secondly, we extract the spatio-temporal features from the individual frame to increase the efficiency of the detection. This approach is evaluated using the UCSD Dataset, which comprises 50 training and 48 testing samples. The effectiveness of this approach has been testified against metrics such as F1 score, Recall, Precision, and Accuracy

Published: April 2024

Molecular ferroelastic with the natural features of mechanical
flexibility and switchable spontaneous strain have attracted widespread
attention in the scientific community due to their potential
applications in tunable gratings, flexible memorizers, strain sensors,
and intelligent actuators. However, most designs of molecular
ferroelastics remain in the stage of blind exploration, posing a
challenge to achieve a functional ferroelastic more effectively. Herein,
we have successfully obtained a molecular ferroelastic,
[MeNH(CH)NH](ReO)
(MeNH(CH)NH
= N,N-dimethylethylenediammonium), under the guidance of the
mono-/double-protonating strategy. The double-protonated
[MeNH(CH)NH](ReO)
undergoes a paraelastic-ferroelastic phase transition with the Aizu
notation of 2/mF-1 at 322 K. Meanwhile, the theoretical
calculation and experimental measurement simultaneously show that
[MeNH(CH)NH](ReO)
possesses good mechanical flexibility, because its elastic modulus
(E) of 8.26 GPa and hardness (H) of 0.45 GPa is smaller
than the average value of organic crystals (E of 12.05 GPa and
H of 0.5 GPa), which makes it promising to apply in wearable
pressure sensors, implantable medical sensors, high-precision tuners,
etc. This work further enriches the molecular ferroelastic family and
demonstrates that mono-/double-protonation is one of the effective
molecular modification strategies for designing ferroelastics.
SIMULATING WHAT LIMITS THE SPREAD OF A HIGH-PROFILE INVASIVE PREDATOR

Published: April 2024

Rapid environmental change and human activity has dramatically
facilitated the spread of invasive species, expanding their impacts
beyond the original recipient communities. Predicting the potential
spread of invasive species and ways to stop it remain challenging, as
several abiotic, biotic, and management factors may alter outcomes.
Among the most problematic invasive species globally, Burmese pythons
(Python bivittatus) have established throughout much of south Florida
(USA) and pose substantial ecological, economic, and societal threats to
the region. To understand the invasion process, we use a new
spatiotemporal modeling framework, the spatial absorbing Markov chain
(SAMC), to model future spread of pythons while accounting for propagule
pressure and mortality risk from three hypothesized sources: (i) cold
exposure, (ii) vehicle strikes on roads, and (iii) removal management
programs. To parameterize this model, we integrated empirical and
model-derived data of python occurrence, movement, and behavior, and
physiology using coupled correlative-mechanistic models. In a simulated
invasion scenario, we found that removal management programs may have
the greatest potential for limiting future spread through long-term
mortality—accounting for 93.6% of all expected mortality and
exceeding both cold exposure (<0.1%) and road mortality
(6.3%). Furthermore, we demonstrate that circuit theory, a model which
does not account for demographic processes, likely overestimates spatial
patterns of connectivity. By examining invasions in a spatiotemporal
framework, SAMC can provide novel information—including spatial
patterns of survival, time-specific movements, and evaluation of
different types of removal management strategies—to guide the
management of invasive species.

Published: April 2024

The evolution of animals and their gut symbionts is a complex
phenomenon, obscured by lability and diversity. In social organisms,
transmission of symbionts among relatives may yield systems with more
stable associations. Here we study the history of a social insect
symbiosis involving cephalotine ants and their extracellular gut
bacteria, which come predominantly from host-specialized lineages. We
perform multi-locus phylogenetics for symbionts from nine bacterial
orders, and map prior amplicon sequence data to lineage-assigned
symbiont genomes, studying distributions of rigorously defined symbionts
across 20 host species. Based on monophyly and additional hypothesis
testing, we estimate that these specialized gut bacteria belong to 18
distinct lineages, of which 15 have been successfully isolated and
cultured. Several symbiont lineages showed evidence for domestication
events that occurred later in cephalotine evolutionary history, and only
one lineage was ubiquitously detected in all 20 host species and 48
colonies sampled with amplicon 16S rRNA sequencing. We found evidence
for phylogenetically constrained distributions in four symbionts,
suggesting historical or genetic impacts on community composition. Two
lineages showed evidence for frequent intra-lineage co-infections,
highlighting the potential for niche divergence after initial
domestication. Nearly all symbionts showed evidence for occasional host
switching, but four may, more often, co-diversify with their hosts.
Through our further assessment of symbiont localization and genomic
functional profiles, we demonstrate distinct niches for symbionts with
shared evolutionary histories, prompting further questions on the forces
underlying the evolution of hosts and their gut microbiomes.
Recent progress in photocathode interface engineering for photoelectrochemical CO2 reduction reaction to C1 and C2+ products
Authors: Kim Jae Hak , Hong Sung Hyun , Ahn ‪Sang Hyun , Kim Soo Young
Published: April 2024

Photoelectrochemical (PEC) systems harness light absorption to initiate
chemical reactions, while electrochemical reactions facilitate the
conversion of reactants into desired products, ensuring more efficient
and sustainable energy conversion in PECs. Central to optimizing the
performance of PECs was the pivotal role played by interface
engineering. This intricate process involved manipulating material
interfaces at the atomic or nanoscale to enhance charge transfer,
improve catalytic activity, and address limitations associated with bulk
materials. The careful tuning of factors such as band gap, surface
energy, crystallinity, defect characteristics, and structural attributes
through interface engineering led to superior catalytic efficiency.
Specifically, interface engineering significantly enhanced the
efficiency of semiconductor-based PECs. Engineers strategically designed
heterojunctions and manipulated catalyst surface properties to optimize
the separation and migration of photogenerated charge carriers,
minimizing recombination losses and improving performance overall. In
this review, we categorized our discussion into five sections focusing
on PECs and interface engineering, providing valuable insights into
recent research trends. Overall, the synergy between PECs and interface
engineering holds tremendous promise for advancing renewable energy
technologies and addressing environmental challenges by offering
innovative solutions for sustainable energy conversion and storage.
Seismic wavefield change preceding the eruption of Shinmoe-dake, Kirishima volcano, Japan, inferred from polarization analysis
Authors: Hirose Takashi , Ueda Hideki
Published: April 2024

A volcanic tremor is a seismic event linked to volcanic processes,
identified by ongoing ground shaking. While there are different theories
regarding the mechanism of volcanic tremors, they play a crucial role in
understanding internal volcanic activities and forecasting eruptions.
Detecting weak volcanic tremor signals before an eruption has remained a
difficult task. This study utilized polarization analysis on continuous
seismograms at Kirishima volcano, Japan, to extract data on retrograde
Rayleigh wave sources. Back azimuth estimates focused on the direction
of the Shinmoe-dake crater before and during the volcanic eruptions in
2011, 2017, and 2018. Rayleigh waves originating from the crater
direction, particularly in the 1.3-2.5 Hz band, were observed starting
around March 2017, approximately 7 months prior to the October 2017
eruption. In the 1.3-2 Hz band, the back azimuths steadily moved closer
to the crater’s direction between January and March 2017. A noticeable
increase in the amplitudes of retrograde Rayleigh waves from the crater
direction was observed starting in August 2016. Enhancing the growth in
amplitude was achieved by utilizing a filter on the seismograms. As
polarization analysis requires only a single three-component
seismometer, this approach allows for the timely identification of weak
Rayleigh waves from the crater direction, even in volcanoes with limited
seismic station coverage. The results obtained in this study contribute
to the growing knowledge on volcanic tremors and their potential use in
volcano monitoring and eruption forecasting.

The Impact of Value Chain Financing on Profitability for South Africa's Edible Oil Manufacturing Companies: Raw Materials and Working Capital Approaches
Authors: Aliamutu Kansilembo , Mkhize Msizi
Published: April 2024

Edible oil manufacturing companies in South Africa generate significant amounts of revenue, which they do not capitalize on. South Africa has no shortage of consumer demand for commodities. The edible oil sector is hampered by poor raw material output in the nation, insufficient financing by value-chain participants, and a shortage of specific effort and understanding in growing the value chain. The research aim was to evaluate the impact of value chain financing on profitability for South Africa's edible oil manufacturing companies via raw materials and working capital approaches. Utilizing secondary data collected from the financial statements of edible oil manufacturing companies from 2012 to 2022. Throughout the research, a positivism paradigm was applied using a descriptive retrospective panel data approach. Multiple regression analysis was used to determine the connection between the value chain financing variables (raw materials as well as working capital) and the profitability of edible oil manufacturing companies in South Africa. On financing in raw material there was a negative correlation among the two variables, but it is not statistically significant (r = -0.030, p =.424). On financing in working capital, there was a positive correlation (r =.201, p =.012), the connection between financing in creditors management and profitability in the edible oil company has a positive correlation (r =.162, p = 0.09) but is not statistically significant. The research found that raw material financing and working capital financing had no statistically significant connection to the profitability of edible oil manufacturing companies in South Africa.

Published: April 2024

The research aimed to explore how different aspects of stakeholder participation correlate with the effectiveness of rural electrification projects in southwestern Uganda. Employing a cross-sectional research design, data was gathered from 32 projects as the primary unit of analysis, with a sample size of 34 projects selected from a total population of 39 rural electrification projects, determined using Krejicie and Morgan's method from 1970. Analysis methods included Pearson correlation and regression. The findings demonstrated a statistically significant positive relationship between communication, compliance, and engagement with the performance of rural electrification projects. Regression analysis further supported these results, showing significant unstandardized coefficients for each respective dimension. Moreover, the regression model indicated that communication, compliance, and engagement, as measures of stakeholder involvement, accounted for 39.5% of the variability in rural electrification project performance in southwestern Uganda. This suggests that other factors not addressed in this study explained the remaining 60.5%. Therefore, the study suggests that comprehensive stakeholder involvement, involving clear communication before and during project implementation, adherence to regulations agreed upon by stakeholders, and active engagement of all parties at each project stage, is crucial for achieving project success.

Predicting students' academic success in tertiary institutions in terms of determining accurately whether a student will be a top 10 in his class, an average student or a dropout is a significant issue in higher education. Therefore, to predict the behavior of a learner, many data mining techniques are used, such as clustering, classification, and regression. In this paper, students’ academic performance prediction model and new features are introduced that have a great influence on student’s overall academic achievement. Twenty features were considered from the dataset obtained from about 200 students using questionnaire and information from the institutions database. The Naive Bayes classifier was used and the experiment was carried out in a WEKA implementation workbench. The attributes were first analyzed for relevance, the analysis showed that a student’s first semester grade point average (GPA) has the highest relevance followed by friends’ study affinity, learning facilities, private home lesson, gender and available transport facilities. One hundred and sixty-nine (169) students’ records were used for the analysis, the model recorded 162 instances that were correctly classified which translates to 95.86% accuracy and incorrectly predicted 4.142%. The experiment showed an excellent performance from the Naive Bayes classifier in predicting the dataset correctly Keywords: Educational Data Mining, Students' Performance Management, Tertiary Institutions, Classification, Naive Bayes Classifier.

A Call to Revamp I.R.C. §121: The Rules, the Reality, and a Path to Tax Parity for Long-Term Homeowners
Authors: Campbell Linda , Martin Kasey , Pitman Marshall K.
Published: April 2024

The Taxpayer Relief Act of 1997 revolutionized how taxpayers reported and, when applicable, paid capital gains tax on the sale of their principal residences. We argue that I.R.C. §121 fails to provide tax parity for many U.S. taxpayers and does not adequately support myriad long-standing governmental initiatives that endorse homeownership. Specifically, it favors short-term homeownership and could substantially penalize homeowners who remain in their principal residence long term. We examine relevant taxation history and the realities that impede tax parity. We suggest modifications that can mitigate tax disparity associated with differences in holding periods and supplement these proposals by addressing tax-reducing provisions that are currently available to all principal residence owners. Our findings highlight a viable step toward mitigating the specific issue related to long-term homeowners as well as stressing that any resulting tax benefits deemed “excessive” for the nation’s wealthiest taxpayers should be dealt with outside of §121.

Insulin resistance is a risk factor for type 2 diabetes, and exercise can improve insulin sensitivity. However, following exercise, high circulating fatty acid (FA) levels might counteract this. We hypothesized that such inhibition would be reduced by forcibly increasing carbohydrate oxidation through pharmacological activation of the pyruvate dehydrogenase complex (PDC). Insulin-stimulated glucose uptake was examined with a crossover design in healthy young men (n = 8) in a previously exercised and a rested leg during a hyperinsulinemic-euglycemic clamp 5 h after one-legged exercise with 1) infusion of saline, 2) infusion of intralipid imitating circulating FA levels during recovery from whole-body exercise, and 3) infusion of intralipid + oral PDC activator, dichloroacetate (DCA). Intralipid infusion reduced insulin-stimulated glucose uptake by 19% in the previously exercised leg, which was not observed in the contralateral rested leg. Interestingly, this effect of intralipid in the exercised leg was abolished by DCA, which increased muscle PDC activity (130%) and flux (acetylcarnitine 130%) and decreased inhibitory phosphorylation of PDC on Ser293 (∼40%) and Ser300 (∼80%). Novel insight is provided into the regulatory interaction between glucose and lipid metabolism during exercise recovery. Coupling exercise and PDC flux activation upregulated the capacity for both glucose transport (exercise) and oxidation (DCA), which seems necessary to fully stimulate insulin-stimulated glucose uptake during recovery.

En varios Estados la norma suprema se ve envuelta en una corriente neoconstitucionalista, en donde los derechos fundamentales se garantizan de manera inmediata y prioritaria, contemplando entre estos la libertad de expresión; sin embargo, hasta qué punto las personas pueden ejercerlo sin vulnerar la integridad personal con enfoque en el ámbito psicológico y moral. Actualmente las redes sociales permiten la expresión de ideas y pensamientos, sin embargo, estos pueden llegar a afectar el núcleo duro de la integridad personal de un tercero. Por lo que se busca analizar el alcance y protección de los derechos a la libertad de expresión e integridad personal, en las redes sociales desde el punto de vista jurídico en el contexto ecuatoriano y colombiano; la investigación emplea una metodología cualitativa y el método doctrinario como el dogmático. De esta forma se concluye que, es necesario imponer limitaciones en la expresión que usa como medio el Internet, dentro del contexto normativo interno y considerando apreciaciones de la comunidad internacional a fin de precautelar otros derechos con una vista general del derecho a la integridad personal tanto psíquica como moral, a más de otros vinculados como el buen nombre, la honra o la seguridad nacional, entre otros; destacando que estas restricciones deberán considerar factores como la necesidad, idoneidad y proporcionalidad.

Published: April 2024

In many countries around the world, tennis is taught in schools. Is Greece ready to introduce the teaching of tennis in both primary and secondary education? Physical education teachers from all over the country answered this question after first attending a seminar that would help them teach the sport of tennis in their schools. Our research had two objectives. The first objective was to evaluate the seminar by the physical education teachers, and the second objective was to find out if they think tennis can be added to the physical education curriculum at school. The results of our study for the first purpose, which was to evaluate the seminar they attended, showed that physical education teachers were very positive in their response, with a percentage of 51.3% agreed and a completely agreed percentage of 43.2%. For the second objective, if they think tennis can be added to the physical education curriculum at school, the answers showed us a high percentage of 53,4% “Agree” and 34,9% “Strongly agree.” The results of our study showed in all the responses that physical education teachers “Agree” to all the questions with a percentage of 52.3% and “Strongly agree” with a percentage of 39.1%. Only 7% selected “Neither agree nor disagree,” 0.5% selected “Disagree,” and 1.1% selected “Strongly disagree.” This showed us that almost everyone was positive about both the seminar project and the teaching of tennis in the school. So, we believe that ways should be found to implement the project, which has only profit to offer to both students and teachers.

A 19-month-old female common marmoset (Callithrix jacchus) was presented with a 4-day history of anorexia and behavioral changes. At presentation, a combination of neurological signs, erosions, and ulcerations of the mucous membranes of the oral mucosa and mucocutaneous junction of the lips were observed, suggesting herpesvirus infection. Although etiological and symptomatic therapy was initiated immediately, the animal died the next day. A necropsy was performed, and gross pathology and pathohistology findings indicated a systemic viral infection. Definitive diagnosis was based on the results of molecular testing that demonstrated the presence of human herpes simplex virus type 1. In conclusion, marmosets are a highly susceptible host for human herpes simplex virus. To reduce the risk of infection and prevent this highly lethal disease in monkeys, contact with humans who have symptomatic or asymptomatic forms of HSV-1 should be limited and accompanied by appropriate hygiene measures.

The aim of this study was to investigate staphylococcal enterotoxins (SEs) by ELISA, and detect the five classical sea, seb, sec, sed, and see genes by real-time PCR in Staphylococcus aureus isolates from raw and pasteurized milk samples. Staphylococcus spp. were isolated from 98 out of 100 raw milk samples, and in 6 out of 100 pasteurized milk samples. On further biochemical tests, S. aureus was isolated in 48 samples (48%) of raw milk (n=100) and in one sample (1%) of pasteurized milk (n=100). Ten (10%) out of 100 raw milk samples were positive for at least one enterotoxin, and the most frequently observed SE was SEA (10%), followed by SEE (7%) and SEB (6%), but none of the isolates were positive for SEC and SED. At least one of the SEs gene types (sea, seb, sec, sed, see) was detected in 45 (93.8%; 45/48) S. aureus isolates from raw milk samples. sec, sea, seb, sed, and see genes were observed in 56.2%, 39.5%, 31.2%, 29.1% and 14.5% of strains respectively. The enterotoxin genes were the single type in 21 (46.7%) of the 45 isolates, there were two in 15 (33.3%), three in six (13.3%), four in two (4.4%), and one (2.2%) in all gene regions. The SE gene was not detected in the S. aureus (n=1) isolate from pasteurized milk. As a result of this study, the presence of enterotoxigenic S. aureus in raw milk was revealed, and it was pointed out that these SEs may contribute to cases of staphylococcal foodborne poisoning (SPF).

Long and short term implications of mineral mining operations in Sierra Leone: A review
Authors: Fayiah Moses , Fayiah Muloma Seibatu
Published: April 2024

Sierra Leone is among the few countries endowed with substantial mineral resources deposits in Africa. This review throws light on the long- and short-term positive impact of the mining sector in Sierra Leone. Over the past decade, the revenue derived from mineral mining has had little impact on the economic development of the country. According to history, extensive mineral mining operations is traced back to the early 1930s. Nonetheless, the inception of mineral extractions in Sierra Leone has been characterized by political instability, war, biodiversity loss, corruption, hardship among others. Based on available literature, mineral extraction in Sierra Leone has directly or indirectly impacted the 1), environment (ecosystem and biodiversity) 2), governance and leadership (stakeholder’s consultation) and 3) economic growth and development. The common negative impact are environmental pollution, degradation and social issues such as sexual violence, teenage pregnancy, early marriage, prostitutions, school dropout and spread of transmissible diseases among other issues. The source of data for this review was acquired from the secondary source. Information was source from both published and unpublished materials of interest. Key words such as mineral mining, mineral resources, mining benefits, mining policies, mining challenges were searched for important information on the subject matter. In some mining edge communities across Sierra Leone, protest and other human right abuses perpetrated by company’s authorities and security officials is common within these communities in Sierra Leone. On the other hand, mineral mining has served as a means of sustainable livelihood booster for deprived mining edge communities in Sierra Leone. Additionally, some mining edge communities in Serra Leone enjoy better economic conditions from the cooperate social responsibility (CSR) scheme of most mining companies. Alternately, mineral mining has also been a source of political tension and tradeoff between local resident and mining companies/governments. To remedy this situation, the government in recent years, has enacted many policies, legislations and regulations that supports the judicious extraction and management of minerals for the benefits of all in Sierra Leone. It is therefore recommended that, best international practices and standard operating procedures related to mining extraction be adopted and applied across all mining sites in Sierra Leone. This will help in mitigating the human right abuses trade-off between mining communities and mining companies for a better future.

A Cu-1Cr-0.1Zr alloy has been subjected to ECAP processing via route Bc and aging at 250-800°C. Electron BackScatter diffraction (EBSD), Transmission Electron Microscopy (TEM) and X-Ray Diffraction Line Profile Analysis (XRDLPA) techniques have been used to unveil some peculiarities of the grain and subgrain structure with a special emphasis on the comparison of the grain size estimated by the three techniques. For the alloy ECAP processed and aged up to 16 passes, the grain size (from EBSD, 0.2 < d < 5 μm), subgrain size (from TEM, d ~ 0.75 μm) and “apparent” average crystallite size (from XRDLPA, d < 0.25 μm) are manifestly different. The results were compared to the published data and analyzed based on the fundamental aspects of these techniques.

Published: April 2024

This study investigated the effect of adding Al–5Ti–1B grain refiner on the solidification microstructure and hot deformation behavior of direct-chill (DC) cast Al–Zn–Mg–Cu alloys. The grain refiner significantly decreased the grain size and modified the morphology. Fine-grained (FG) alloys with grain refiners exhibit coarse secondary phases with a reduced number density compared to coarse-grained (CG) alloys without grain refiners. Dynamic recrystallization (DRX) was enhanced at higher compression temperatures and lower strain rates in the CG and FG alloys. Both particle stimulated nucleation (PSN) and continuous dynamic recrystallization (CDRX) are enhanced in the FG alloys, resulting in decreased peak stress values (indicating DRX onset) at 450°C. The peak stress of the FG alloys was higher at 300-400°C than that of the CG alloys because of grain refinement hardening over softening by enhanced DRX.

Published: April 2024

OBJECTIVE

To evaluate the effect of abdominal thrusts as a synergistic procedure to IV apomorphine administration on the occurrence and rate of onset of successful induction of emesis in dogs.

ANIMALS

31 client-owned dogs.

METHODS

Dogs in which induction of emesis via IV apomorphine was prescribed by the attending clinician were prospectively randomized to either receive abdominal thrusts performed by a nurse or clinician or to have no physical interventions performed following IV apomorphine administration. Data collected included signalment, weight, reason for emesis, time from suspected ingestion to presentation, time from the dog’s last meal to presentation, dose of apomorphine administered in milligrams, and time from apomorphine administration to emesis.

RESULTS

Emesis induction was successful in 14 of 14 (100%) of the dogs in the abdominal thrust group and 13 of 17 (76.5%) in the control group (P = .02). In dogs with successful emesis, median time to emesis was 90.5 seconds (range, 36 to 348 seconds) in the abdominal thrust group and 106 seconds (range, 37 to 360 seconds) in the control group (P = .29).

CLINICAL RELEVANCE

Abdominal thrusts were associated with an increased frequency of successful emesis in dogs following IV apomorphine, but did not shorten the rate of onset of emesis in dogs that vomited. Application of abdominal thrusts may be beneficial in dogs in which emesis is indicated and that do not have a clear contraindication.
