Authors: Ghouri Nawab Ali , Waris Muhammad
Published: April 2024

Barley is an important field crop. The present study was designed to identify the efficient seed dressing synthetic fungicide against Ustilago hordei causing covered smut of barley. The treatments included three seed dressing fungicides (Bayton 10 DS, Topsin-M, Dividend-Star 36 F.S) and 4th treatment was set as control to compare their efficacy against the disease. The findings of the treatment indicated that crop stand, seedling mortality, smut infected grains and yield characters of barley were found significantly (P<0.05) controlled with treatment of seed inoculation/ seed dressing with treated fungicides. Fungicide Topsin-M ranked first and sowing of barley with Topsin inoculated seed resulted in 198.67 seed germination m-2, 0.70% seedling mortality, 1.34 grains infected by covered smut, 2.08 percent infected grain, 413.33 spikes m-2, 38.16 grains spike-1, 10.75cm spike length and 3220.70kg ha-1 grain yield. The fungicide Bayton 10 DS ranked second and sowing of barley with Bayton inoculated seed resulted in 182.67 seed germination m-2, 1.11% seedling mortality, 2.14 grains infected by covered smut, 3.05 percent infected grain, 395.67 spikes m-2, 36.50 grains spike-1, 10.43cm spike length and 3037.70kg ha-1 grain yield. The seed dressing fungicide Dividend-Star 36 FS ranked third and sowing of barley with Dividend inoculated seed resulted in 171.67 seed germination m-2, 1.69% seedling mortality, 2.51 grains infected by covered smut, 4.85 percent infected grain, 380.67 spikes m-2, 34.61 grains spike-1, 10.30cm spike length and 2980.70kg ha-1 grain yield. The control plots, where the barley was sown without seed inoculation ranked least (4th) and resulted in 159 seed germination m-2, 3.68% seedling mortality, 3.81 grains infected by covered smut, 10.63 percent infected grain, 333.33 spikes m-2, 34.67 grains spike-1, 10.03cm spike length and 2591kg ha-1 yield of the grain. Concluded findings showed that all the treatments showed effective results as compare to control and minimized the covered smut disease in barley crop; however, among all treated seed dressing fungicides, Topsin-M fungicide was identified with better findings to minimize the disease as compared other above captioned fungicides.

Advancing Edge Computing with Federated Deep Learning: Strategies and Challenges
Authors: Nadella Geeta Sandeep
Published: April 2024

Abstract: Edge computation (EC) represents a transformative architecture in which cloud computing services are decentralized to the locations where data originates. This shift has been facilitated by the integration of deep learning (DL) technologies, notably in eliminating latency issues commonly referred to as the "echo effect" across various platforms. In typical EC-enabled DL frameworks where data producers are directly involved, it is often necessary to share data with third parties or edge/cloud servers to facilitate model training. This process, however, raises significant concerns regarding synchronization with high data rates, seamless migration, and security, consequently exposing the system to privacy vulnerabilities. These challenges can be addressed through the adoption of Federated Learning (FL), which provides a robust mechanism to mitigate risks associated with data loss, ensure data freshness, and enhance privacy.

EVALUATING THE ACUTE DERMAL TOXICITY AND SKIN IRRITATION OF THE TEMEPHOS IMPREGNATED CELLULOSE NANOFIBER INTENDED FOR MOSQUITO LARVICIDE
Authors: Pengiran Hazirah , Kamaldin Jahangir bin , Fen Leo Bey , Sabri Nurhidayah
Published: April 2024

Cellulose nanofiber (CNF) derived from kenaf bast fiber has the potential to be used as a biodegradable and renewable larvicide nanocarrier due to its excellent physicochemical properties. However, acute dermal toxicity testing of CNF with high aspect ratios and fibrous morphology is limited even though its exposure to the skin is possible. Herein, this study aims to investigate the skin irritation effect and acute dermal toxicity of kenaf CNF (KCNF 2.3 % w/v) & kenaf CNF impregnated with temephos (KCNF+T 2.3 % w/v) following OECD test guideline 402. Female Sprague Dawley rats were exposed with KCNF 2.3 % w/v and KCNF+T 2.3 %w/v, respectively, at a dose level of 2000 mg (kg body weight)-1 for 24 hours followed by 14 days of observation for skin irritation effect, mortality, abnormal behaviours, and clinical signs of toxicity. Our result indicated that no skin irritation effect, treatment-related mortality, and abnormal behaviours in both exposed groups. However, KCNF+T 2.3 % w/v treated rats showed mild cholinergic signs of toxicity compared with the absence of clinical signs of toxicity in KCNF 2.3 % w/v treated rats. The KCNF 2.3 % w/v and KCNF+T 2.3 % w/v were non-skin irritants with the LD50 value > 2000 mg (kg body weight)-1 and therefore classified as non-hazardous chemicals of Category 5 according to the GHS system.

Published: April 2024

Calcium phosphates (CaPs) are frequently implemented in bone tissue engineering, especially in orthopaedics and dentistry, due to the resemblance of their inorganic constituent with bone or dental tissue. They have excellent biocompatibility, osseointegration and osteoconduction properties. The compounds are also widely available in nature and biological systems. Despite their excellent properties, various mechanical and physical factors affect their cell adhesion, proliferation, and bioactivity. Different applications have been highlighted such as synthesis techniques, coatings and composite scaffolds to utilise the bioactive characteristics of CaP in tissue engineering. A systemic data search was initiated using the “Article title, Abstract, and Keywords” search category of Scopus database to retrieve the original articles published in this field. With the aid of Scopus database and VOS Viewer software, the most contributing authors, countries, institution were retrieved. The most cited publication, publication year, and keyword co-occurrence network analysis facilitate the significant research focus and trends. This bibliometrics approach aims to quantify and analytically evaluate the research efficiency contributed in this specific area to the scientific community and reviews the substantial research trends of calcium phosphate application in dentistry.

Authors: Zhen Li , Roslan Husniyati , Rahman Nawal Radhiah Abdul , Kamaruddin Anis Farhan
Published: April 2024

Torus palatinus and torus mandibularis are common localised bony overgrowths of cortical bone, which are non-pathological. As tori have been widely discovered for ages, there are some new findings in the 21st century. This review aims to summarise the aspect of aetiology, sociodemographic features, clinical features, treatments and functions of tori. A search was performed in PubMed and Google Scholar databases from 1950 until 2022. From the total of 4,150 studies evaluated, 61 articles were included in this review. The aetiology of tori has shown that Y chromosomes and some signal factors (Notch3, SMAD9, LRP5 V171) may affect its occurrence. The prevalence among people of East Asian is higher than among West African heritage, and the age range is 20-50 years old. Clinical features of tori are represented by size, shape and location, and sometimes by symptoms. Patients who need the removal of tori are treated by surgical removal using burs/bone chisel and mallet/peeling it with Er:YAG laser/piezoelectric surgery, plus postoperative anti-inflammatory drugs, which give a good healing effect. In addition, tori can be used as an autogenous bone graft to repair periodontitis bone defects in maxillary sinus lift cases and to increase bone thickness for dental implants. Tori can also be a marker for hyperparathyroidism and bioarcheological investigation. In conclusion, updates on these aspects have been found. However, complex aetiology needs to be further confirmed. Moreover, treatment is worth tracking, and its function as autologous bone deserves to be studied in other body parts.
CHARACTERIZATION OF THE ADAPTIVE NKG2C+ NK CELL IN HUMAN CYTOMEGALOVIRUS INFECTED INDIVIDUALS: A SYSTEMATIC REVIEW
Authors: Okpoluaefe Suruthimitra , Mahmad-Najhan Farah Hanina , Hassan Norfarazieda
Published: April 2024

The significance of adaptive natural killer (NK) cells in the subject pertaining to human cytomegalovirus (HCMV) infection is emphasized by the preferential expansion of a specific subset, termed NKG2C+ which can recognize an array of HCMV-encoded proteins. Until today, the subject of adaptive or ‘memory-like’ NK cells remains controversial, but more emerging evidence shows the cells' ability to ‘remember’. The purpose of this systematic review was to appraise recent literature that centered on the expansion of adaptive NKG2C+ NK cells driven by HCMV infection, specific to ‘human’. Databases including PubMed, Scopus, and JURN were systematically searched to source relevant journal articles published between 2011 and 2021, in a period of 10 years. Full-text terms such as ‘NKG2C+ adaptive NK cells’ AND ‘human cytomegalovirus’ were applied to retrieve related articles. This systematic review is comprised of continuous data on the expansion of NKG2C+ NK cells driven by HCMV and other HCMV-affiliated receptors, immune cells, and diseases with appropriate implementation of distinct inclusion and exclusion criteria. The authors evaluated the risk of bias and quality evidence of the data independently. The study is beneficial by gathering the evidence to conclude the occurrence of adaptive or ‘memory-like’ properties in human NK cells.
Physics-informed Neural Networks for the Improvement of Platform Magnetometer Measurements
Authors: Styp-Rekowski Kevin , Michaelis Ingo , Korte Monika , Stolle Claudia
Published: April 2024

Space-based measurements of the Earth’s magnetic field with a good
spatiotemporal coverage are needed to understand the complex system of
our surrounding geomagnetic field. High-precision magnetic field
satellite missions form the backbone for sophisticated research, but
they are limited in their coverage. Many satellites carry so-called
platform magnetometers that are part of their attitude and orbit control
systems. These can be re-calibrated by considering different behaviors
of the satellite system, hence reducing their relatively high initial
noise originating from their rough calibration. These platform
magnetometer data obtained from non-dedicated satellite missions
complement the high-precision data by additional coverage in space,
time, and magnetic local times. In this work, we present an extension to
our previous Machine Learning approach for the automatic in-situ
calibration of platform magnetometers. We introduce a new
physics-informed layer incorporating the Biot-Savart formula for dipoles
that can efficiently correct artificial disturbances due to electric
current-induced magnetic fields evoked by the satellite itself. We
demonstrate how magnetic dipoles can be co-estimated in a neural network
for the calibration of platform magnetometers and thus enhance the
Machine Learning-based approach to follow known physical principles.
Here we describe the derivation and assessment of re-calibrated datasets
for two satellite missions, GOCE and GRACE-FO, which are made publicly
available. We achieved a mean residual of about 7 nT and 4 nT for low-
and mid-latitudes, respectively.
Gene networks governing the response of a calcareous sponge to future ocean conditions reveal lineage-specific XBP1 regulation of the unfolded protein response
Authors: Posadas Niño , Conaco Cecilia
Published: April 2024

Marine sponges are predicted to be winners in the future ocean due to
their exemplary adaptive capacity. However, while many sponge groups
exhibit tolerance to a wide range of environmental insults, calcifying
sponges may be more susceptible to thermo-acidic stress. To describe the
gene regulatory networks that govern the stress response of a calcareous
sponge, Leucetta chagosensis (class Calcarea, order Clathrinida),
individuals were subjected to warming and acidification conditions based
on the climate models for 2100. Transcriptome analysis and gene
co-expression network reconstruction revealed that the unfolded protein
response (UPR) was activated under thermo-acidic stress. Among the
upregulated genes were two lineage-specific homologs of X-box binding
protein 1 (XBP1), a transcription factor that activates the UPR.
Alternative dimerization between these XBP1 gene products suggests a
clathrinid-specific mechanism to reversibly sequester the transcription
factor into an inactive form, enabling the rapid regulation of pathways
linked to the UPR in clathrinid calcareous sponges. Our findings support
the idea that transcription factor duplication events may refine
evolutionarily conserved molecular pathways and contribute to ecological
success.

Authors: George Alex , Conneely Shannon E. , Mangum Ross , Fasipe Titilope , Lupo Philip , Scheurer Michael
Published: April 2024

Objective: To delineate the natural history of splenic
complications other than the loss of splenic function in children with
sickle cell disease (SCD), we performed a retrospective chart review of
patients with SCD treated at the Texas Children’s Hospital.
Methods: We determined the dates of diagnoses of splenic
complications, the number of ASSC events, and hydroxyurea treatment in
patients with SCD. We also examined the association of hydroxyurea
therapy with the onset and severity of ASSC. Results: The
cumulative prevalence of splenic complications was 24.7% for
splenomegaly, 24.2% for ASSC, 9.6% for hypersplenism, and 5.6% for
splenectomy. The cumulative prevalence of all splenic complications was
highest in patients with hemoglobin Sβ (69.2%),
intermediate in hemoglobin SS (33.3%), low in hemoglobin SC (9.0%),
and non-existent in hemoglobin Sβ . The overall
event-rate of ASSC was 8.3 per hundred patient-years. The event-rate was
28.4 in the hemoglobin Sβ , 10.9 in hemoglobin SS,
and 3.5 in hemoglobin SC Patients with hemoglobin SS and hemoglobin Sβ
on hydroxyurea therapy had a significantly higher
occurrence of ASSC than those who were not, with event-rates of 14.2 and
3.1, respectively. The event-rate was also higher for children who
started hydroxyurea before age 2 years than for those who started after
this age (19.8 and 9.2 respectively). Conclusions: The
prevalence and severity of splenic problems vary widely between
different sickle cell genotypes, with hemoglobin Sβ
having the most severe complications. Hydroxyurea therapy is strongly
associated with incidence of ASSC, particularly when initiated before
two years of age.
Short-Term Electric Power and Energy Balance Optimization Scheduling Based on Low-Carbon Bilateral Demand Response Mechanism from Multiple Perspectives
Authors: LI JUAN , LI Yonggang , Liu Huazhi
Published: April 2024

Carbon emissions limit the output demand of traditional fuel-generating
units, significantly affecting the electric power and energy balance
scheduling mechanisms of modern power systems. To address this, we first
analyzed the short-term electric power and energy balance from a dual
perspective, along with the electro-carbon coupling mechanism of dynamic
dispatching on the source-load side. Based on this analysis, we
constructed a framework for low-carbon bilateral demand response
(LCBDR). Subsequently, based on the carbon emission flow theory, the
carbon emission index information of the demand response system was
obtained. Therefore, the short-term electric power and energy balance
optimal scheduling model for LCBDR is established to achieve a
low-carbon economy. In this study, the enhanced decision tree classifier
(EDTC) algorithm is used to predict the electricity consumption behavior
of transfer load (TL) user load, and an improved ‘ ε-greedy’ strategy
particle swarm optimization (PSO) algorithm is proposed to realize the
coordinated optimization of daily operational cost and daily carbon
emission of the regional power grid. Finally, by setting up three
different perspectives of the simulation examples, the proposed method
can effectively realize the regional power grid’s low-carbon,
economical, and efficient operation. The feasibility of the model can be
verified via the IEEE-30 bus system.
On the relationship between Ural blocking and Arctic-midlatitude thermal gradient
Authors: Cadau Marco , Messori Gabriele , Gaetani Marco , Fosser Giorgia , Bordoni Simona , Buizza Roberto , Sannino Gianmaria
Published: April 2024

In this study, the relationship between the interannual variability of
Arctic-midlatitude thermal gradient (AMG) and the winter atmospheric
blocking frequency in the Ural region (UBF) is investigated in the ERA5
reanalysis product from 1940 to 2023. In particular, the paper focuses
on the large-scale atmospheric circulation patterns associated with high
UBF concomitant to weak AMG and vice versa, revisiting the more common
and documented relationship connecting intense Ural blocking activity to
strong AMG. Results show that displacements of the atmospheric blocking
from the Ural region towards the Arctic lead to anomalous southerly
thermal advections at polar latitudes and stronger AMG. On the other
hand, high blocking frequency co-occurring in the Ural, Greenland and
Chukotka regions lead to weaker AMG by limiting northward heat
advections towards the Arctic region. These findings highlight a more
complex picture of the role of subpolar atmospheric circulation in
controlling the AMG.
Locating boundaries between locked and creeping regions at Nankai and Cascadia subduction zones
Authors: Sherrill Elizabeth M , Johnson Kaj M. , Jackson Noel McCay
Published: April 2024

Interseismic coupling maps and, especially, estimates of the location of
the fully coupled (locked) zone relative to the trench, coastline, and
slow slip events are crucial for determining megathrust earthquake
hazard at subduction zones. We present a physically motivated
interseismic coupling inversion that explicitly incorporates locked
zones with boundaries bordering an updip transition zone creeping at
constant stress and a downdip transition zone with creep rate
distributions consistent with updip propagation of the creep front into
the locked zone. We show that the locked zone at Cascadia is west of the
coastline and 10 km updip of the slow slip zone along much of the
margin, widest (25-125 km, extending to ~22 km depth) in
northern Cascadia, narrowest (0-70 km) in central Cascadia, with moment
accumulation rate equivalent to a Mw 8.78 and Mw 8.89 earthquake for
300- and 500-year earthquake cycles. We find a steep gradient in creep
immediately below the locked zone, indicative of propagating creep,
along the entire margin. At Nankai, we find three distinct zones of
locking (offshore Shikoku, offshore southeast Kii peninsula, and
offshore Shima peninsula) with a total moment accumulation rate
equivalent to a Mw 8.73 earthquake for a 150-year earthquake cycle. The
bottom of the locked zone is nearly under the coastline for all three
locked regions at Nankai and is positioned 0-5 km updip of the the slow
slip zone. In contrast with Cascadia, creep rate gradients below the
locked zone at Nankai are generally gradual, consistent with stationary
locking.
Bristlecone Pine Maximum Latewood Density as a Superior Proxy for Millennium-length Temperature Reconstructions

Published: April 2024

Bristlecone pine (Pinus longaeva) (PILO) trees exhibit exceptional
longevity. Their tree-ring width (TRW) series offer valuable insights
into climatic variability. Maximum latewood density (MXD) typically
correlates better with temperature variations than TRW, yet PILO MXD
records are non-existent due to methodological challenges related to
their tree-ring structure. Here, we used an X-ray Computed Tomography
(X-ray CT) toolchain on 51 PILO cores from the California White
Mountains to build a chronology that correlates significantly (r=0.66,
p<0.01) with warm-season (March-September) temperature over a
large spatial extent. This led to the first X-ray CT-based temperature
reconstruction (1625 – 2005 CE). Good reconstruction skill (RE=0.51,
CE=0.32) shows that extending MXD records across the full length of the
PILO archive could yield a robust warm-season temperature proxy for the
American Southwest over millennia. This breakthrough opens avenues for
measuring MXD in other challenging conifers, increasing our
understanding of past climate further, particularly in lower latitudes.

Introducción: Paciente de sexo femenino de 86 años de edad, seguida en la unidad de hematología de nuestro hospital por una anemia normocitica-normocromica que tras tratamiento con darbopoetina alfa 40 mcg subcutánea semanal durante tres meses, es diagnosticada de poliglobulia. Se solicitó flebotomía terapéutica de 400 cc de sangre. Tras su realización, se realiza control analítico resultando hemoglobina:14.8mg/dl y hematocrito:42.2% (valores en rango).
Desarrollo de la experiencia: El procedimiento se llevó a cabo en casa de la paciente sin necesidad de movilizarla de su cama, pues se encuentra encamada. Extraemos la cantidad de sangre indicada en la prescripción(400cc), sin ninguna complicación.
Conclusiones: En este caso pudimos realizar un procedimiento de rango hospitalario en el domicilio de la paciente, liberando, por un lado, a los familiares de la “carga” del desplazamiento al hospital, y por otro, protegiendo la paciente de complicaciones relacionadas con la asistencia hospitalaria (infecciones nosocomiales, desorientación entre otras).
Así mismo, con menos recursos, pudimos realizar una atención humanizada y segura, logrando el objetivo terapéutico.

Introducción: La HaD evita la estancia en el hospital de pacientes proporcionándoles en su domicilio el mismo tratamiento y cuidados que se le prestarían en el hospital. En algunos casos esto no se consigue y las/os pacientes requieren el traslado a hospitalización convencional (THC). El objetivo del trabajo es analizar con qué frecuencia ocurre el THC, sus motivos y proponer un modelo de predicción basado en características de los pacientes que influencian el THC.
Método: Estudio retrospectivo, multicéntrico, que aprovecha las características registradas en los pacientes atendidos en mayo de 2021 en 9 Servicios de HaD de Osakidetza-Servicio Vasco de Salud, completados con datos del alta (fecha y destino). Se comparó el porcentaje de THC no programado en pacientes con /sin diferentes variables binarias. Con las significativas se realizó una regresión logística binaria y a partir de sus resultados se construyó un modelo predictivo simplificado.
Resultados: Se analizaron 1129 episodios de HaD de las modalidades de acortamiento o evitación de ingreso. 139 (12,3%) requirieron THC, que en 105 (9,3%) fue no programado (THCNP). 32 de estos fallecieron en el hospital y 44 retornaron a HaD. En función de la modalidad asistencial, el grupo de patología y la puntuación en test de Barthel, los pacientes se clasificaron en 3 grupos cuya frecuencia de THCNP fue de 3.4, 11.5 y 20.5 % respectivamente.
Conclusiones: El THCNP de pacientes de H a D ocurre con frecuencia diferente en función de ciertas características de los pacientes y se puede predecir a partir de ellas.

COVID-19 has impacted people’s lives worldwide as a global pandemic. It is a shocking health issue and generates other economic and societal problems. With its many citizens, Indonesia faces limitations in dealing with this pandemic. The research was initiated due to global COVID-19, which affects Indonesia economically and socially. They utilized local wisdom to support religious minorities via humanitarian efforts. This research explores the charitable and philanthropic efforts of minority religious communities such as Ahmadiyah, Shia, Baha'i, and Sapta Dharma in Yogyakarta, which often face negative perceptions in Indonesia. This study uses qualitative methods to illustrate how minority religious groups participate in helping others in responding to the pandemic. Data was collected through in-depth interviews, Focused Group Discussions, and documentation. The results showed that minority religious groups in Indonesia have the initiative and actively participate in assisting needy people around them as their responsibility as Indonesian citizens, despite the discrimination and hostility they face because of their beliefs. Philanthropic motivations based on religious values, universal humanity, and moral responsibility as a religious group can be viewed as local wisdom. The existence of cultural views in Indonesia for help and mutual assistance makes aid acceptable as a form of brotherhood, which is inversely proportional to the theological rejection of the group.

The new wave of buzzword technology has launched the Chat Generative Pre-Trained Transformer (ChatGPT). The ChatGPT application, besides its benefits, has created a worldwide heated debate about its impact on quality and the future of education. Artificial intelligence and other computing technology advancements have dominated the academic scene The main aim of this paper is to map out the impact of the use of ChatGPT on academic writing at Moroccan universities. The researchers have designed a questionnaire for the purpose of this study. The research targets university students and educators for their possible expertise in academic writing. The distribution intends to ensure representation across levels of education, age, and gender. One hundred and eighty volunteers participated by providing insightful data about the investigation. The results of the study revealed that participants confirm the value and efficacy of ChatGPT as a tool; Moroccan respondents admit that ChatGPT can be both beneficial and harmful to students. Students at different educational levels venture into the use of ChatGPT without guidance and training. They are at a crossroads without direction signs in implementing ChatGPT appropriately, so they are astray about whether to use ChatGPT academically, how, and where. The educators, though they are provided with accounts in iThenticate plagiarism detector, stay aloof and claim training in their turn, but the educational authorities, ministry, and universities continue to keep taciturn.

Covid-19 merupakan pandemic yang sudah melanda dunia sejak akhir tahun 2019. Covid-19 mulai melanda Indonesia pada awal tahun 2020. Pada awal periode, pertumbuhan pandemic covid-19 ini sangat cepat. Bahkan rasio kasus meninggal akibat covid-19 ini tergolong cukup tinggi. Jika dilihat dari kurva pertumbuhan kasus meninggalnya, nampak bahwa kurvanya melandai pada awal namun menaik signifikan setelahnya. Oleh karena itu artikel ini mengimplementasikan model non-linear yang dalam hal ini menggunakan model gompertz, model logistic, dan model Weibull pada pertumbuhan kasus meninggal akibat covid-19 di Indonesia pada awal kemunculannya yaitu periode April 2020 sampai Maret 2021. Kemudian dari ketiga model itu akan dipilih model terbaik dengan membandingkan nilai R-Square dari masing-masing model. Model yang memiliki R-Square terbesar menandakan model yang paling baik digunakan. Setelah dilakukan pemilihan ternyata model gompertz memiliki nilai R-Square terbesar yaitu 0,9987, sehingga model yang paling cocok untuk data covid-19 ini adalah model gompertz.

Scientific and technological innovation has always been the main driver of economic growth and social progress. The rapid development of technology and advances in the internet have made it possible to disseminate information and interact more easily. With the rapid development of technology, a lot of information is shared every second, resulting in big data in terms of different, complex variables. ANN is the result of work in the computer field that is inspired by the capabilities of the human brain which consists of biological neural networks. In recent years, the use of artificial neural networks (ANN) has increased. The research carried out aims to analyze the survival capabilities of Titanic passengers who experienced an accident while sailing and sank. This research uses initial data of 1309 observations with 14 variables. From the research results, 2 hidden variables are the most accurate with an accuracy of 80.5%, compared to the number of hidden variables of 3 (79%) and 4 (79%). So it can be concluded that the number of hidden variables with the same number of hidden screens does not have a significant difference in accuracy

Economic growth in developed nations often leads to a surge in transportation needs, particularly in large cities. This can manifest as increased accident rates, environmental degradation, social strain, and most notably, traffic congestion. Addressing these challenges requires a multifaceted approach, balancing social, environmental, and economic considerations while prioritising public safety and health. The study contributes to the search for solutions by investigating traffic flow patterns on urban expressways. The research compares southbound and northbound lane speeds, analysing the relationship between speed and vehicle occupancy in both directions. By leveraging secondary quantitative data collected over seven consecutive days with Speedlane ProTM Counter Classifier radar technology, the study aims to identify potential causes of congestion. It is expected that the northbound lanes may experience higher traffic volume and greater variability compared to the southbound lanes. This research can inform traffic management strategies and contribute to reduced congestion in urban areas.

Tensegrity structures consist of multiple struts or cables that are interconnected and ideal for deployable structures. Given the challenges of controlling the strut’s deformation, active cables are more preferred and commonly studied in the deployment of tensegrities. The selection of the active cables becomes important as the deployment of tensegrities is highly dependent on the construction cost and computational time. This paper presents three different deployable schemes considering different sets of active cables. The deployable schemes were studied in this study to investigate the bending deformation of a human spine-inspired bio-tensegrity model. The shape change strategy involves a computational approach based on sequential quadratic programming to optimise the cable force elongation. A total of nine shape change analysis cases were conducted on the bio-tensegrity model to undergo deformation under three different schemes and three uni-directional targeted coordinates. The bending ability of bio-tensegrity models, the convergence curve, and axial forces were all discussed. It was found that the deployment scheme S3 is the most efficient scheme for the model to achieve different targets in uni-directional mode. This study is useful for applications such as deployable structures, automation, and robots

Gravel is a natural raw material used in concrete mixtures. However, more of this scarce resource was used, which reduced the amount of gravel-based coarse aggregates that could be produced. As a result, efforts to preserve natural coarse aggregates for future generations were critical. So, an innovation to replace this natural coarse aggregate was required. The dumping of cockle shell waste by the cockle trade emits a stinking smell and pollutes the environment. This study investigates the density, compressive, splitting tensile and flexural strengths of concrete containing cockle shell as a coarse aggregate substitute. Four concrete mixes were prepared by integrating diverse contents of cockle shell as 0%, 10%, 20% and 30% partial replacement of coarse aggregates by weight of gravel. Concrete becomes less dense as a large amount of cockle shell is integrated. Utilization of cockle shell up to 10% enhances the compressive strength of concrete. However, increasing the amount of cockle shell by up to 30% can improve the splitting tensile and flexural strength of concrete
