JAYA algorithm based selective mapping for PAPR reduction in GFDM systems
Authors: Bouslam Karima Ait , Amadid Jamal , Bennioui Fatim-zehra , Cherij Dounia , Iqdour Radouane , Zeroual Abdelouhab
Published: April 2023

Several techniques have been used to tackle the PAPR problem in
Generalized Frequency Division Multiplexing (GFDM) systems. The
Selective mapping (SLM) remains the most used alone or in combination
with optimization algorithms in order to find optimal phase factors.
Unfortunately, the complexity of implementation and the use of many
control parameters are the main drawbacks of these techniques. This
paper proposes an enhanced SLM technique to further improve the PAPR
reduction in the GFDM system without increasing the system complexity.
The proposed technique, i.e., JAYA-SLM, combines the JAYA algorithm with
the SLM scheme. The simulation results demonstrate that the proposed
JAYA-SLM technique is highly efficient in PAPR reduction without
increasing the system complexity, wherein fewer used parameters. Also,
it improves the system’s power saving and the Bit-Error-Rate (BER)
performance when compared to others existing methods.
Crowd Evacuation Simulation in Flowing Fluids
Authors: Chen Qiang , Zou Xunjin , Ye Yunqing , Zhu Zhenmin
Published: April 2023

In this paper, we propose an integrated model for simulating the
interaction between crowds and fluid particles. Our focus is on
simulating evacuation motion for crowds in the face of sudden floods.
Our model treats both the crowd and the water as fluid particles, which
allows us to incorporate various forces such as pressure, shear,
buoyancy, and active forces to drive the agents. Additionally, we have
designed a minimum rotational path-planning algorithm for agents to
search for safe destinations during evacuations. To develop practical
crowd evacuation strategies, we observed and studied survival techniques
from whirlpools and sudden changes in water levels during floods. Our
simulated evacuation results provide plausible strategies for crowds to
survive dangerous floods.
Detecting Extreme Temperature Events Using Gaussian Mixture Models

Published: April 2023

Extreme temperature events have traditionally been detected assuming a
unimodal distribution of temperature data. We found that surface
temperature data can be described more accurately with a multimodal
rather than a unimodal distribution. Here, we applied Gaussian Mixture
Models (GMM) to daily near-surface maximum air temperature data from the
historical and future Coupled Model Intercomparison Project Phase 6
(CMIP6) simulations for 46 land regions defined by the Intergovernmental
Panel on Climate Change (IPCC). Using the multimodal distribution, we
found that temperature extremes, defined based on daily data in the
warmest mode of the GMM distributions, are getting more frequent in all
regions. Globally, a 10-year extreme temperature event relative to
1980-2010 conditions will occur 15 times more frequently in the future
under 3.0C of Global Warming Levels (GWL). The
frequency increase can be even higher in tropical regions, such that
10-year extreme temperature events will occur almost twice a week.
Additionally, we analysed the change in future temperature distributions
under different GWL and found that the hot temperatures are increasing
faster than cold temperatures in low latitudes, while the cold
temperatures are increasing faster than the hot temperatures in high
latitudes. The smallest changes in temperature distribution can be found
in tropical regions, where the annual temperature range is small. Our
method captures the differences in geographical regions and shows that
the frequency of extreme events will be even higher than reported in
previous studies.
Ionospheric Disturbances generated by the 2015 Calbuco Eruption: Comparison of GITM-R simulations and GNSS observations
Authors: Tyska Justin James , Deng Yue , Zhang Shun-Rong , Lin Cissi Ying-tsen
Published: April 2023

Volcanic eruptions provide broad spectral forcing to the atmosphere and
many previous studies have examined the IT disturbances caused by
volcanic eruptions through both observations and modeling. Understanding
the primary mechanisms that are relevant to explain the variety in
waveform characteristics is still an important open question for the
community. In this study, Global Navigation Satellite System (GNSS)
Total Electron Content (TEC) data are analyzed and compared to
simulations performed by the Global Ionosphere-Thermosphere Model with
Local Mesh Refinement (GITM-R) for the first phase of the 2015 Calbuco
eruption that occurred on 22 April. A simplified source representation
and spectral acoustic-gravity wave (AGW) propagation model are used to
specify the perturbation at the lower boundary of GITM-R at 100 km
altitude. This modeling specification shows a good agreement with GNSS
observations for some waveform characteristics such as travel/onset
times and relative magnitudes. Most notably, GITM-R is able to reproduce
the significance of AGWs as a function of radial distance from the vent,
showing acoustic dominant forcing in the near field (<500 km)
and gravity dominant forcing in the far-field (>500 km).
The estimated apparent phase speeds from GITM-R simulations are
consistent with observations with ~10% difference from
observation for both acoustic wave packets and a trailing gravity mode.
Relevance of the simplifications made in the lower atmosphere are then
discussed and test changes to the assumed propagation structure, from
direct propagation to ground-coupled propagation, show some improvement
to the data-model comparison, especially the second acoustic wave-packet
Artificial Space Weathering to Mimic Solar Wind Enhances the Toxicity of Lunar Dust Simulants in Human Lung Cells

Published: April 2023

During NASA’s Apollo missions, inhalation of dust particles from lunar
regolith was identified as a potential occupational hazard for
astronauts. These fine particles adhered tightly to spacesuits and were
brought accidentally into the living areas of the spacecraft. Apollo
astronauts reported that exposure to the dust caused intense respiratory
and ocular irritation. This problem is a potential challenge for the
Artemis Program, which aims to return humans to the Moon for extended
stays in this decade. Since lunar dust is “weathered” by space
radiation, solar wind, and the incessant bombardment of micrometeorites,
we investigated whether treatment of lunar regolith simulants to mimic
space weathering enhanced their toxicity. Two such simulants were
employed in this research, Lunar Mare Simulant-1 (LMS-1), and Lunar
Highlands Simulant-1 (LHS-1), which were applied to human lung
epithelial cells (A549). In addition to pulverization, previously shown
to increase dust toxicity sharply, the simulants were exposed to
hydrogen gas at high temperature as a proxy for solar wind exposure.
This treatment further increased the toxicity of both simulants, as
measured by the disruption of mitochondrial function, and damage to DNA
both in mitochondria and in the nucleus. By testing the effects of
supplementing the cells with an antioxidant (N-acetylcysteine), we
showed that a substantial component of this toxicity arises from free
radicals. It remains to be determined to what extent the radicals arise
from the dust itself, as opposed to their active generation by
inflammatory processes in the treated cells.
The rise of GLOF danger: trends, drivers and hotspots between 2000 and 2020
Authors: Taylor Caroline J , Robinson Tom R , Dunning Stuart , Carr J. Rachel
Published: April 2023

Between 2000 and 2020, the potential for glacial lake outburst floods
(GLOFs) and the exposure and vulnerability of downstream populations to
them, have changed across the globe. The impact of these changes on the
danger posed by GLOFs, as well as the relative importance of each
factor, remains contentious, making the implementation of appropriate
management and risk reduction strategies challenging. Here we show that
globally, since 2000, the number of people exposed to GLOF impacts has
increased by 3.2 million (27% increase), to a total of 15 million
people as of 2020. The largest increase in GLOF danger occurred across
the Andes, while only nine countries experienced a decrease in GLOF
danger, most notably in Nepal and Kyrgyzstan. Importantly, contrary to
the notion presented in current research, we find the changes in the
threat from GLOFs have not been universally driven by either lake
change, exposed population, or vulnerability; instead, the primary
driver varies both at regional- and national-scales. Further, we show
that vulnerability to GLOF impacts has declined almost everywhere, but
this decline has been insufficient to offset the combined growth in the
number and area of glacial lakes and downstream exposure. We highlight
the Andes as a global hotspot for high, and rapidly increasing,
contemporary GLOF danger, and suggest the region be targeted for further
research. Critically, we show that mitigating GLOF impacts will require
bespoke solutions depending on the relative impact of lake conditions,
exposure and vulnerability on changing GLOF danger.
Identification of Source Faults of Large Earthquakes in the Turkey-Syria Border Region Between AD 1000 and Present, and their Relevance for the 2023 Mw 7.8 Pazarcık Earthquake
Authors: Carena Sara , Friedrich Anke , Verdecchia Alessandro , Kahle Beth , Rieger Stefanie , Kübler Simon
Published: April 2023

The February 6th, 2023, Mw 7.8 Pazarcık earthquake in the Turkey-Syria
border region raises the question of whether such a large earthquake
could have been foreseen, as well as what is the maximum possible
magnitude (Mmax) of earthquakes on the East Anatolian fault system and
on continental transform faults in general. To answer such questions,
knowledge of past earthquakes and of their causative faults is
necessary. Here, we integrate data from historical seismology,
paleoseismology, archeoseismology, and remote sensing to identify the
likely source faults of fourteen Mw ≥ 7 earthquakes between AD 1000 and
the present in the region. We find that the 2023 Pazarcık earthquake
could have been foreseen in terms of location (the East Anatolian Fault)
and timing (an earthquake along this fault was if anything overdue), but
not magnitude. We hypothesize that the maximum earthquake magnitude for
the East Anatolian Fault is in fact 8.2, i.e. a single end-to-end
rupture of the entire fault, and that the 2023 Pazarcık earthquake did
not reach Mmax by chance only. In fact, we suggest that such unusually
large events are hard to model in terms of recurrence intervals, because
they need a very specific set of circumstances to line up before they
can happen. We also conclude that seismic hazard assessment along
continental transforms cannot be done on individual fault systems, but
must include neighboring systems as well, because they are not
kinematically independent at any time scale.

Published: April 2023

Chirostoma jordani is an endemic species of Mexico, whose populations due to different natural and anthropogenic causes, have experienced a notable decline in recent decades, endangering their permanence in their natural habitat, including the Xochimilco canals. Therefore, this study focused on updating the status of the species in Xochimilco through an ecophysiological analysis with a bioenergetic approach, using as a model the elements (P and R) of the general energy balance equation. The measured performance indicators of the species during an annual cycle were: analysis of the structure of size (total length, TL and weight, W), body composition of the tissue: wet weight (WW), dry weight (DW), body water content (WC), nitrogen and energy content, growth rate (GR) = production (P), and metabolic rate (R) in relation to body weight in two contrasting seasons of the year (dry and rainy), as well as assimilation efficiency (P + R). The physicochemical dynamics of the habitat of the species was evaluated in all the sampling months, through eight water quality variables and was correlated with the previously indicated performance measures using discriminant analysis. The composition by sizes indicated that the spawning season and the entry of recruits into the population take place during the dry season (February - May), reaching the highest growth rates in the period March - April: 0.23 mm TL/ day, as well as the highest values in: assimilation (2,457.2 cal/g DW/day), energy expenditure in metabolism and tissue energy enrichment (CI95%: 3,493.6 – 4,762.6 cal/g DW), as opposed to the rainy season of the annual cycle: August – November, which is defined by the greatest environmental heterogeneity with extreme values of pH, total solids and nitrite concentrations that interact as constraints on the performance of the population. It is concluded that the population of C. jordani in the study area is subject to extreme environmental pressures, and the quantitative indicators used are of great value to identify and diagnose the risk status of the species and should be used to delimit future actions in its management and conservation.

Published: April 2023

Dental abnormalities have been sporadically reported in patients treated as children for acute lymphoblastic leukemia (ALL) with multi-agent chemotherapy, with and without radiation. Reports included delayed dental development, microdontia, hypoplasia, agenesis, V-shaped roots, shortened roots, and cervical root resorption. These anomalies in pediatric patients require regular dental follow-up and sometimes highly complex treatment. We describe a well-documented case of a 19-year-old male who presented with such anomalies 12 years after treatment with several chemotherapy agents for ALL, and discuss the resultant disruption of normal tooth development that led to the ensuing abnormalities.
Creeping Attachment Observed in RT2 following Labial Frenectomy: A Case Report
Authors: Malhotra Sakshi , Tewari Shikha
Published: April 2023

Introduction: Aberrant frenal attachment and shallow vestibule in the anterior mandible facilitates plaque accumulation, inflammation, and root exposure of the mandibular central incisors, especially where the “pull syndrome” is noted.

Case Report: A 22 years old systemically healthy female patient complained of slight mobility and increased spacing in relation to lower front teeth. Clinical examination revealed Cairo recession type 2 (RT2) gingival recession in relation to mandibular central incisors and hyperplastic frenum with fan shaped attachment to gingival margin of mandibular central incisors. Frenectomy was performed using conventional surgical technique. After 14 days of surgery 0.5 mm of creeping attachment as well as reduction in recession width at apical level of recession was observed in relation to mandibular central incisors. The achieved clinical results remained stable till 6 months of follow-up.

Conclusion: This case report suggests that frenectomy using conventional surgical technique may yield acceptable clinical outcomes and esthetics in RT2 gingival recession.
First Analysis of Expression of Napsin-A in Ovine Pulmonary Adenomatosis of Sheep and Goat at Duhok Governorate
Authors: Abdullah Mahdi A.
Published: April 2023

Ovine Pulmonary Adenomatosis is a chronic respiratory disease of sheep or contagious lung cancer of sheep, and less commonly of goats. A total of 4061 lung samples were selected randomly from slaughtered sheep and goats. All samples of lungs with typical lesions were fixed in 10% neutral buffered formalin and examination is performed by macrocsopical and microscopical observation. To perform IHC technique, we used TMA with a polymer system by application of specific markers Napsin A. Results showed 35 lungs suspected from natural cases are diagnosed as OPA. Histologically results showed that the presence of multiple proliferations foci of neoplastic cells in the epithelial cell of alveoli and bronchi, these proliferations appears either papillary or as impression of solid growths appearance or acinar shape which is classified as classical and atypical form. The current study found that the expression of Nnapsin A was observed in 85.71% of the OPA as a granular cytoplasmic staining but there was staining in the nucleus of tumor cells. In conclusion, these findings indicate for the first time that Napsin A is extremely specific for adenocarcinoma of lung in primary origin and use of this important biomarker is guaranteed to help disconnect primary pulmonary adenocarcinoma for diagnosis from other types of lung cancer.

Authors: Seraphin Hugues , Yallop Anca
Published: April 2023

The dating services industry has grown strongly over the past five years worldwide, with dating services increasing in popularity, contributing billions to the hospitality industry. In this opinion paper we carry out a preliminary examination of the connection between the dating industry and the hospitality industry and conduct a a pilot study as platform for further research seeking to examine the connections between these industries. The preliminary findings indicate that the dating services industry and the hospitality industry are interconnected, and that entertainment, service interaction and the hospitality venue’s ambiance are central factors to both the dating and hospitality industries. Nevertheless, future research must investigate further intersectional gaps, more specifically, to examine the synergies between business partners delivering products and services which are placed at this intersection between dating and hospitality.
