Authors: Muhajarah Kurnia , Fabriar Silvia Riskha
Published: June 2022

Sejarah politik Islam adalah sejarah dakwah, yakni berbagi amar ma`ruf nahi munkar. Pemerintahan Islam merupakan kepemimpinan moral yang sangat peduli dalam perwujudan keadilan dan kesejahteraan. Pemerintahan ini adalah sebuah upaya penegakan kebajikan pada muka bumi, khususnya terhadap perempuan. Tujuan berdasarkan penulisan ini merupakan menganalisa mengenai bagaimana persepsi ulama mengenai keterlibatan perempuan pada bidang politik yang merujuk pada keadilan, kesetaraan, dan kepemimpinan, dan bagaimana keterlibatan perempuan pada bidang politik di masa Rasulullah, Khalifah, dan peran perempuan Indonesia pada masa pra Kemerdekaan sampai masa kini. Studi ini memakai jenis penelitian kepustakaan, bersifat kualitatif pada pendekatan sejarah. Hasil penelitian ini menunjukkan bahwa dari beberapa kajian literatur dan pendapat ulama, tidak ada nash dalam islam yang melarang keterlibat perempuan dalam politik, utamanya dalam pemerintahan suatu negara. Perempuan juga bertanggung jawab membangun pemerintah sebagaimana yang disinyalir dalam Surat at-Taubah ayat 71. Salah satu bukti yang bisa dipaparkan melalu konteks lintas sejarah, mulai dari jaman Rasulullah SAW, hingga saat ini, khususnya di Indonesia terlihat peran serta aktif beberapa tokoh perempuan dalam dunia politik dan pemerintahan.

Authors: Lv Cuimei , Jue Yabo , Guo Xi , Ling Minhua , Yan Denghua
Published: June 2022

Economic and social development have worsened the situation of water pollution and even the ecological environment. It is helpful to quantify the water pollution ecological environment losses for decision-makers to formulate reasonable pollution control plans. However, the current quantitative analyses led by economic methods are not comprehensive and systematic. Therefore, based on the emergy theory and method system of eco-economics, this study analyzed the internal energy flow process of the water-polluted ecosystem, discussed the composition of water-polluted ecological environment loss, and proposed a quantitative model of water-polluted ecological environment loss based on the emergy analysis method. It can reasonably quantify the ecological environment loss caused by water pollution and provide a reference for optimizing regional industrial layout, scientifically formulating pollution control planning, and promoting the sustainable development of the ecosystem. Taking Kaifeng City in Henan Province as an example, the rationality of the model is verified. The results show that the annual average total energy value of water pollution ecological environment loss in Kaifeng City is 3.83 × 1020sej, equivalent to 145 million yuan (0.76) of Kaifeng's gross domestic product (GDP) in 2018.
Effect of blocked sediments on flow characteristics and associated backwater effect in drainage pipes
Authors: Sun Bin , Tong An , Yang Runzhi , Chen Shizhe , Li Zhiwei
Published: June 2022

The study of hydraulic characteristics of water flow affected by blocked sediment is vital to assess discharge capacity in pipes with sediment sand to understand the process of pollutant and fine sand aggregation. The aim of this paper is to study the blocking effect of permeable sediments on non-full flow in circular pipe and to analyze hydraulic characteristics with backwater. Experiments and numerical simulations were performed and the porous media model is used to simulate the flow in permeable blocked sediments. To evaluate the degree of congestion, the backwater ratio β is proposed. The backwater ratio is positively proportional to blocked sediment height and inversely proportional to blocked sediment particle size and flow value. Cross-sectional velocity in the backwater zone decreases significantly and tends to be uniform as backwater ratio increases. Furthermore, the development of secondary flows and velocity distributions influenced by backwater height is discussed. The dimensionless shear velocity in backwater zone shows an exponential decrease as the backwater ratio increases, which greatly increases the possibility of further sediment deposition.

GC-MS Identification and Quantification of the Synthetic Cannabinoid MDMB-4en-
PINACA in Cannabis-derived Material Seized in the Turin Metropolitan Area
(Italy)
Authors: Gerace Enrico , Seganti Fabrizio , Di Corcia Daniele , Vincenti Marco , Salomone Alberto
Published: June 2022

Background:

The presence of the synthetic cannabinoid receptor agonist MDMB-4en-PINACA in
adulterated low-THC cannabis products was recently highlighted in several reports. Moreover, numerous intoxication
cases involving MDMB-4en-PINACA have been described.

Objective:

In order to monitor the diffusion of cannabis products containing MDMB-4en-PINACA in our territory,
a total of 358 cannabis-derived samples (213 vegetal material and 145 resins) seized in the period November
2020 - February 2021 in the western Piedmont Area (Italy) was analyzed.

Methods:

General screening analyses for traditional and synthetic cannabinoids were performed by a GC-MS
device operating in full scan mode (40-600 amu). The MDMB-4en-PINACA was quantified by means of a specific
GC-SIM-MS protocol purposely developed and validated, while the quantification of THC, CBD, and
CBN was carried out by a GC-SIM-MS method routinely employed in our laboratory.

Results:

MDMB-4en-PINACA was detected in 12 out of 358 samples (3.4% of the total). Among these, the
molecule was found in 11 vegetal materials and in one resin sample. Considering solely the analysis of the 213
herb products, a positive rate of 5.2% was found for the presence of MDMB-4en-PINACA in these samples.
MDMB-4en-PINACA was found in the seized materials at concentration levels ranging from 0.4 up to 6.3 mg/g
(mean 2.5 mg/g; median 1.7 mg/g). Concerning the traditional cannabinoids, the THC concentration was in the
interval 3-43 mg/g (mean 12 mg/g; median 7 mg/g), while CBD was found at higher concentrations in all specimens,
specifically in the range 47-140 mg/g (mean 87 mg/g; median 80 mg/g).

Conclusions:

The adulteration of low-THC cannabis products with synthetic cannabinoid receptor agonists is
widespread today. Since these substances are potentially more toxic than THC, their consumption poses a high
risk of overdose for unaware users and a health-threatening situation. This study confirmed the sporadic presence
on the market of CBD-prevalent cannabis products adulterated with MDMB-4en-PINACA.

Macrocephala in Hyperuricemia and Gouty Arthritis Rat Models
Authors: Luo Yiyuan , Qian Xvwu , Jiang Ying , Jiang Yuchen
Published: June 2022

Aims:

Atractylodes macrocephala is a traditional Chinese medicine with a variety of
pharmacological activities. This study aimed to evaluate its anti-hyperuricemia and antiinflammatory
effects on gout, and to preliminarily explore its mechanism.

Methods:

The hyperuricemia rat model was established by intraperitoneal injection of oteracil potassium
and intragastric gavage of yeast powder solution. And the acute gouty arthritis (GA) model
was established by injecting monosodium urate (MSU) suspension. In the study of the antihyperuricemia
effect of Atractylodes macrocephala, the healthy male Sprague-Dawley rats were randomly
divided into the blank group, hyperuricemia group allopurinol group as well as low, moderate
and high dose groups of Atractylodes macrocephala decoction (N=8 rats in each group). Serum, liver
and kidney tissue samples were collected from each group. Serum uric acid (UA), adenosine deaminase
(ADA) and xanthine oxidase (XOD) levels in each group were detected by enzyme-linked immunosorbent
assay (ELISA). Protein levels of ADA and XOD in liver tissues were detected by Western
blot, and renal histological changes were observed by Hematoxylin-eosin (H＆E) and Masson
staining. In order to investigate the anti-inflammatory effect of Atractylodes macrocephala, the
healthy male Sprague-Dawley rats were randomly divided into the blank group, GA group, colchicine
group, high, moderate and low dose groups of Atractylodes macrocephala decoction (N=8 rats in each
group), and serum and synovial tissue of each group were collected. Then the level of serum interleukin
(IL)-1β and tumor necrosis factor (TNF)-α was observed by ELISA, and the histological changes
of synovial tissue were observed by H＆E staining. Besides, the expression of adenosine monophosphate-
activated protein kinase (AMPK) /silent information regulator (SIRT) 1/ nuclear factor kappa B
(NF-κB) protein in synovial tissue was observed by Western blot and immunohistochemistry. The
markers of M1 and M2 macrophages, inducible nitric oxide synthase (iNOS) and arginase-1 (ARG1)
were observed by Western blot and immunofluorescence.

Results:

Atractylodes macrocephala could reduce the production of UA by inhibiting the level of
ADA and XOD, and could improve renal injury and fibrosis. In addition, Atractylodes macrophages
could reduce the levels of IL-1β and TNF-α, activate AMPK/SIRT1 signaling pathway, and inhibit
the activation of NF-κB and the polarization of macrophages to a pro-inflammatory phenotype.

Conclusion:

Atractylodes macrocephala shows good anti-hyperuricemic and anti-inflammatory effects,
and its anti-inflammation pharmacological activity may be related to the inhibition of M1
macrophage polarization and NF-κB activation through activating AMPK/SIRT1.
Giant Vertebral Artery Aneurysm in Behçet’s Disease: A Rare Case and
Review of the Literature
Authors: Topaloğlu Ömer Faruk , Kılınçer Abidin , Nayman Alaaddin
Published: June 2022

Background:

Behçet's disease is a chronic inflammatory disease that can involve systemic organs and vascular structures. Arterial system involvement is rarer than the venous system, it is the major cause of death. Vertebral artery (VA) involvement is rare and there are a limited number of reported cases in the literature. In this report, we aimed to present the imaging findings of a case of Behçet's disease with a giant aneurysm originating from the right VA.

Case report:

A 35-year-old woman with a 10-year history of Behçet's disease applied to our center with complaints of pain on the right side of the neck. CT angiography showed a 7.5x6.5 cm sized saccular aneurysm in the superior of the right hemithorax adjacent to the mediastinum, with contrast filling the V1 segment of the VA. The VA aneurysm in our case had no relation with the subclavian artery and showed filling from the contralateral VA. The described findings were demonstrated in Doppler examination, phase-contrast MRI, conventional and CT angiography.

Conclusion:

Behçet's disease is a chronic inflammatory disease that can involve the arterial system. Although VA involvement has not been reported frequently, all arterial structures may be affected by this vasculitic process.

b)fluoranthene, and Chrysene in Tocotrienol Concentrates Using Dual
Solid-phase Extraction and Gas Chromatography-Mass Spectrometry
Authors: Hor Jia Yi , Hassan Norfarizah Hanim , Zulkarnain Musfirah , Latip Razam Abd , Nidzam Mohammad Saiful , Wong Yong Foo
Published: June 2022

Background:

Polyaromatic hydrocarbons (PAHs) are a class of toxic compounds commonly
found in edible vegetable oils as a result of contamination through food processing. Among the wide variety
of PAHs existing in edible oils, benzo(a)pyrene (BAP), benzo(a)anthracene (BAA), benzo(
b)fluoranthene (BBF), and chrysene (CHR) are commonly monitored due to their toxicity, carcinogenic
and teratogenic properties.

Materials and Methods:

In this context, we described a combination of liquid-liquid extraction and dual
cartridge solid-phase extraction (dSPE) system for the extraction of BAP, BAA, BBF, and CHR in palm
oil derived tocotrienol rich fraction (T3RF), followed by their analysis using GC-MS operating in selected
ion monitoring mode (SIM).

Results:

The separation was effected using a DB-5HT column (30 m × 0.25 mm × 0.25 μm) that can operate
at a high temperature limit of 400 °C, which enables the separation of the PAHs in < 28 min. The
calibration curves were correlated within the range of 1.5-25 μg/ L, with detection limits (S/N: 3.3) of
0.48-1.35 μg/L, and relative standard deviations of ≤ 0.07% and ≤ 6.85% were achieved for intra-day
retention times and peak areas.

Conclusion:

The proposed sample preparation and GC-SIM workflow greatly reduces interference
caused by tocotrienol homologues and enables the quantitative determination of BAP, BAA, BBF, and
CHR in T3RF and palm fatty acid distillates.

Zinc oxide nanoparticles were synthesized via a wet chemical method using zinc nitrate
and sodium hydroxide. This fabrication procedure is reliable, cheap, and yields the most stable byproducts.
Characterization was carried out via several analytical techniques to check the authenticity
of the synthesized nanomaterial, thus revealing that the obtained ZnO nanoparticles could be used in
medical interventions as a safe option.

Microindentation, X-ray phase analysis, optical and electron microscopy have been used to study the microstructure and bulk physical and mechanical properties (hardness, reduced modulus of elasticity, plasticity index, elastic recovery parameter) of two samples of the binary hypereutectic alloy Al90Gd10 (hereinafter at.%). The first sample was obtained by rapid cooling of the melt at a rate of 1000 deg/sec at a high pressure of 10 GPa, the hardening temperature was 1800 K. The second sample was obtained by pressing the original sample at a high pressure of 5 GPa without melting. Compared to the original sample, the microstructure of both samples is crushed and compacted. The structure of the original sample is represented by two equilibrium phases αAl and Al3Gd. In the sample without melting, in addition to the αAl and Al3Gd phases, a phase with the composition Gd55Al45 was found; in the sample with melting, a phase with the composition Al92Gd8 was found. Features of the structure morphology and changes in the phase composition of samples obtained under high pressure lead to a change in the physical and mechanical properties of the studied alloy.

Published: June 2022

Theoretical and numerical studies of nonlinear acoustic effects arising from the propagation of initially harmonic waves in polycrystalline solids with saturation of amplitude-dependent internal friction have been carried out. Two main types of hysteresis are considered: elastic and inelastic. A comparative analysis of the regularities of nonlinear effects is carried out and the characteristics of nonlinear quasi-harmonic waves in such media are determined: amplitude-dependent losses and changes in propagation velocity, as well as amplitudes of higher harmonics. A method for determining the type of polycrystal hysteresis based on the analysis of theoretical and experimentally established amplitude dependences of nonlinear effects is proposed.

The structure, IR absorption, luminescence, and luminescence excitation spectra of La0.99xYxEu0.01BO3 orthoborates (0 ≤ x ≤ 0.25) synthesized at 970°С were studied at 0 ≤ x ≤ 0.99. An increase in х leads to a sequential change of the structural state of these compounds. At 0 ≤ x ≤ 0.1, the samples are single-phase and have the aragonite structure. Within the range of 0.1 < x ≤ 0.8, the samples are two-phase: the vaterite phase is observed along with the aragonite structure. At 0.8 < x ≤ 0.99, the samples are single-phase and have the vaterite structure. Correspondence between the structure and spectral characteristics of these compounds was established. It is demonstrated that with an increase in the Y3+ concentration, the vaterite phase is formed first in the bulk of microcrystals having the aragonite structure and then in the entire sample. It is shown for the first time that a band with the maximum of 469 nm is observed in the luminescence excitation spectrum (LES) of samples having the vaterite structure and is absent in samples having the aragonite structure. It is revealed that a band in the luminescence spectrum, corresponding to the 5D0→7F0 electron transition, as well as 469-nm-band in the LES, can be an indicator of the structural state of the sample.

Нарушение соотношения Тейлора в условиях высокоэнергетических внешних воздействий
Authors: Малашенко В.В.
Published: June 2022

The motion of an edge dislocation ensemble in a binary alloy under high strain rate deformation is theoretically analyzed. Within the framework of the theory of dynamic interaction of defects (DID) an analytical expression for the dependence of the dynamic yield stress on the dislocation density is obtained. The conditions for the violation of the Taylor relation under high-energy external influences are determined. The experimentally observed nonmonotonic dependence of the dynamic yield strength on the dislocation density is explained. The minimum of this dependence is due to the competition between the influence of various structural defects on moving dislocations. This minimum takes place during the transition from the dominance of dynamic drag by one type of defects to the dominance of another type defects.

The spectrum was obtained and the time dependences of the fractoluminescence signals were studied during the destruction of the quartz surface by "microcutting" perpendicular to the (0001) axis. An analysis of the obtained data showed that clusters of the 4 smallest "primary" cracks appear during fracture. The formation of cracks is associated with the destruction of barriers that prevent the movement of dislocations along slip planes. The crack sizes are several nm, and the growth rate is several m/s. The size distribution of cracks has a power law form.

This paper presents the results of studying the lateral photovoltaic effect in hybrid structures based on SiO2/Si depending on the nature of the conductivity of the material of the upper layer (Fe is a metal, Fe3O4 is a semimetal, TiO2 is a semi-insulator). It is shown that this effect is observed in hybrid structures in which a depleted region with a significant band bending is formed at the SiO2/Si interface. Theoretical calculations of the lateral photovoltage based on the energy parameters of the band diagrams showed that an increase in the sensitivity of the lateral photoelectric effect is associated with an increase in the built-in potential at the SiO2/Si interface. It has been established that the transient characteristics of the lateral photoelectric effect, such as the rise and fall times of the photovoltage signal, are determined by the configuration of the RC-filter in the near-contact region, which depends on the conductivity of the upper layer. It is shown that, in the case of the lateral photovoltaic effect, current transfer occurs along the inversion layer, and the upper layer serves to generate a quasi-pn junction at the SiO2/Si interface.

Pandemic and Resilience— An Analysis of Love in the time of Cholera and the Plague
Authors: R Saranya , B Dr. Evangeline Priscilla
Published: June 2022

The article proposes to provide an insight into Pandemic Literature revealing the impact of pandemic on society as well as the remarkable human resilience. Human history has witnessed a number of pandemics like cholera, plague, and the current covid-19. The word ‘pandemic’ is derived from the Greek words ‘pan’ and ‘demos’. Pan means all and demos means people or crowd. Pandemic is an infectious disease widespread over a large part of the world. Resilience is the human ability to recover quickly from adverse circumstances. Love in the Time of Cholera by Gabriel Garcia Marquez is a classic piece of pandemic literature. The author says that lovesickness is a literal illness. The story takes place in the backdrop of a cholera outbreak. The marked effect of cholera on people’s life and the remarkable human resilience are highlighted in the article. The protagonist’s outburst in the end of the novel shows the surge of resilience. The analysis of The Plague by Albert Camus, the noted French writer throws light on helpless human beings unable to change their destinies. The writer’s absurdist point of view is revealed. The novel begins with the onslaught of plague in the Algerian city of Oran. Besides the sufferings of people, the change of human attitudes and the trait of resilience are also depicted by the author.

Musculoskeletal manifestations (MSM) frequently occur in systemic sclerosis (SSc) and imply a variety of rheumatic symptoms and clinical features, from arthralgia to arthritis, contractures, tendon friction rubs, tenosynovitis, myalgia, muscle tenderness,  and myositis. The objective of the study was to determine the prevalence of joint manifestations in clinical findings, as well as frequency and type of radiographic changes in 56 patients with the limited and diffuse form of SSc; to define the correlation between musculoskeletal hand changes in SSc and specific antibodies (antinuclear antibodies- ANA), as well as with antibodies specific for particular forms of SSc (anti-topoisomerase-1 antibodies- ATA, anticentromere antibodies- ACA); and to test the correlation between specific cardiopulmonary manifestations in SSc, and frequency and type of musculoskeletal changes. The obtained results indicated a high frequency of joint manifestations in SSc, which were estimated by clinical and radiographic examinations. Joint involvement in SSc was underestimated in clinical trials, as it occurred more frequently than expected. Radiographic hand findings in tested SSc patients indicated the presence of arthritis, erosions, joint space narrowing, radiological demineralization, acro-osteolysis, flexion contractures, and calcinosis. Hand involvement was an important cause of morbidity, which seriously affected the quality of life in patients with SSc. Various forms of joint and bone involvements could represent the base for introducing an innovative approach to treating musculoskeletal hand damage in SSc.

Abstract: This paper focuses on reducing the manual involvement of farmer in the field by using an automated irrigation system. So we have included IOT in our project and the coding required in it is done in the Arduino IDE platform. We have taken a microcontroller that is Node MCU and had connected all the sensors in it to operate respectively. We have set a particular value to which if the moisture content detects less than the motor will on automatically or else it will be off. It conserves the water and also manages the amount of water efficiently for plants. It results in reducing human labour, effort, and errors due to human negligence. During the day, solar panels give power to the system and store the energy, allowing it to run at night. It detects the amount of moisture in the soil using a moisture sensor. The pump mechanism is triggered when the moisture content of the soil falls below a specified level for the plant/crop, and the plant/crop is irrigated. On receiving the desired level of irrigation the pumping system is switched off automatically. Keywords: IOT, Automated Irrigation, Solar Source, Save Water.

Abstract: This project's primary purpose is to bridge the gap between deaf and hearing persons, which will benefit those with hearing impairments who employ a simple and effective way of sign language. Sign language is a visual language used by the deaf community. It employs body language, hand gestures, and facial expressions. Indian Sign Language is one of the most significant and commonly utilised modes of communication for individuals with speech and hearing difficulties. This web application facilitates communication for deaf and speech-impaired individuals. The primary focus of these new web application and natural language processing technologies is the conversion of spoken or written language into sign language. In this web application, users can record their speech using a microphone or text as input utilising NLP-based speech recognition. If the video is missing from the database, the word is spit out and the associated video is displayed. This technique has made communicating with deaf individuals simple and practical. Keywords: NLP, Speech to text, sign language translation.

Published: June 2022

Abstract: Various studies indicate that fatigueness in drivers leads to road accidents. It can lead to serious injuries like brain damage or it can lead to death. Therefore preventing people from harming the countermeasure device is necessary as a reliable solution. This study therefore came up with a new way of explaining the driver's fatigueness. This example uses the Haar Cascade algorithm, next to the OpenCV library to keep an eye on the real-time video of the driver and critique the driver's eyes. The Eye Aspect Ratio (EAR) is used in this measurement device to determine if the eyes are open or closed. The Mouth Aspect Ratio (MAR) is also used as an important element while this model describes the driver's fatigueness as the driver begins to yawn just before the driver feels fatigue. If the driver is found to be fatigue, a warning signal is issued.

Abstract: In this work, automatic bird species recognition systems were developed, and their identification methods were investigated. Automatically identifying bird calls without physical intervention has been a large and tedious endeavor for major studies in various subfields of taxonomy and other ornithology. This task uses a two-step identification process. In the first phase, an ideal dataset was created containing all recordings of different bird species. Next, the sound clip was subjected to various sound pre-processing techniques such as pre-emphasis, framing, silence removal, and reconstruction. A spectrogram was generated for each reconstructed sound clip. The second step used a neural network given with the spectrogram as input. A convolutional neural network (CNN) classifies sound clips and recognizes bird species based on input characteristics. In the above system, a real-time implementation model was also designed and executed.

Abstract: In the educational sector, new ideas have aimed to increase the efficiency and speed of grading. As a result of these changes, automatic grading techniques have been established to solve some of the problems of grading specialized courses. With the rapid advancement of technology, it's no surprise that automatic grading systems for problems other than typical multiplechoice questions have been designed. According to research, automatic grading techniques are extremely advantageous to teachers because it would take them much too long to evaluate complex assignments without them. These automated grading techniques are really not meant to take the place of human grading; rather , they're designed to assist teachers in efficiently grading and analyzing information. Automation is slowly becoming a part of the educational process, and now we're heading in the right direction. Automating the grading process also helps in avoiding the human error generated while manually checking the answer sheets and provides a sense of uniformity in answer sheet checking and hence is more fair.

Abstract: Just like natural human intelligence, Artificial Intelligence (AI) can be explained as the intelligence demonstrated by machines, or rather how the machines and models are trained to predict outcomes and give answers in a way that mimic human intelligence. The goal of artificial intelligence is to provide software that can reason on input and explain the output through its various methods. Artificial Intelligence has found its applications in almost every sector in every industry – ranging from finance to marketing to general business management. Similarly, Data Science deals with decision making based on the insights gathered from data analysis rather than merely replying upon the decision maker's intuition and experience. This paper explores with how Data Science and Artificial Intelligence has transformed the way businesses operate and hence changing the strategic decision making and operations landscape in medium scale as well as large sized businesses.

Improving the Initial Conditions of Hydrological Model with Reanalysis Soil Moisture Data
Authors: Liu Lingxue , Ao Tianqi , Zhou Li
Published: June 2022

The initial conditions (e.g., soil moisture content) of the hydrological
model, which is usually obtained from the warm-up of the hydrological
modeling, significantly impact the simulation efficiency. However,
spending the valuable data in warm-up instead of calibration and
validation is luxurious. In order to improve hydrological simulation
efficiency in the case of no warm-up phase, this paper proposes a
methodology to fill the gap via improving the initial conditions of the
hydrological model using an alternative global soil moisture dataset.
Specifically, three soil moisture (SM) variables of the initial
conditions from the Block-wise use of the TOPMODEL (BTOP) model and
EAR5-Land reanalysis data were adopted and conducted correlation
analysis. Several traditional curve-fitting functions and the
state-of-art technical, long-short term memory (LSTM), were applied to
develop the relationship between BTOP and EAR5-Land SM variables in the
Fuji and Shinano River Basin, Japan. Furthermore, four configured
hydrological simulations evaluated the benefits of the proposed
methodology for improving the initial conditions. As a result, LSTM
outperforms the traditional curve-fitting method in constructing the
relationship between variables in time and space. Moreover, the
hydrological simulation cases using the initial conditions related to
the SM from the ERA5-land performs better than the case without the
warm-up phase, and the simulated discharge process approaches the
“optimal” case with the warm-up phase. It is confirmed that the
proposed methodology helps improve the initial conditions of the
hydrological model using reanalysis soil moisture data.

Published: June 2022

Diffuse leptomeningeal glioneuronal tumor (DLGNT) is characterized by
widespread leptomeningeal lesions with focal parenchymal involvement. We
present a child with a large intramedullary spinal cord lesion, whose
biopsy revealed a biphasic astrocytic tumor consistent with pilocytic
astrocytoma. Next-generation sequencing revealed a KIAA1549-BRAF
fusion, 1p/19q co-deletion, and no IDH1 mutation. Methylation
profiling demonstrated a calibrated class score of 0.98 for DLGNT.
Despite morphologic similarities to pilocytic astrocytoma and lack of
oligodendroglial/neuronal components or leptomeningeal dissemination,
the molecular profile definitively classified the tumor as DLGNT. This
case highlights the importance of molecular and genetic testing in
diagnosing pediatric central nervous system tumors.
BLOW UP IN FINITE TIME OF SOLUTIONS TO A LESLIE-GOWER PREDATOR-PREY MODEL IN ABSCENCE OF THE MIDDLE PREDATOR.
Authors: Said Kouachi , Zaidi Abdelhamid
Published: June 2022

In order to study the asymptotic behavior, several authors claimed
global existence in time of solutions to a tritrophic food chain models
following a modied Leslie-Gower formulation considering the interactions
between three species: a generalist top predator depredating on a middle
predator, that in turn is depreds a prey. To the contrary it is shown
nite time blow-up in such models can occur. We show in this work that
blow up in nite time persists even when the intermediate (middle)
predator is abscent to the contrary to what it is claimed by Kundu and
Patra (2022, [13]). It is shown under some restrictions on the
parameters, the model has bounded solutions for all positive initial
conditions. We show that this is not true. Solutions to the model can
blow up in nite time, for initial data suciently large, even under the
restrictions derived by the authors. We can show same results even for
small initial data but we concentrate our proofs for the rst case. We
also show similar results for the spatially extended system. We
illustrate all our results through numerical simulations.

Published: June 2022

Multiple morphological abnormalities of the sperm ﬂagella (MMAF) is an
important cause of male infertility and is defined as absent, short,
coiled, bent irregular flagella. In this study, we identified a novel
missense mutation (c.1414G>A; p.V472M) in Cilia and
flagella associated protein 47( CFAP47, NG_016381.2) in two
unrelated patients with asthenoteratozoospermia. In addition to the
typical MMAF phenotype very analogous to that of Cfap47 mutant
male mice, the two patients also presented abnormal morphology of sperm
heads, mitochondrial sheath disorganization, and defects of sperm
annulus. Further functional experiments confirmed that the expression of
CFAP47 was markedly reduced in the spermatozoa of the patients.
Moreover, coimmunoprecipitation and immunofluorescence showed that
CFAP47 might regulate CFAP65 and CFAP69 through physical interactions
and is thus involved in sperm morphogenesis. In conclusion, we reveal a
novel recurrent mutation in CFAP47 and further expand the
clinical and mutational spectrum of CFAP47, finally providing
important guidance for genetic counseling and targeted treatment.
Reducing FFT Operations for FMCW Radars Range Detection
Authors: Amjadian Avin , Mirzakuchaki Sattar
Published: June 2022

Due to the increasing demand for small, low-cost, high-resolution
radars, frequency-modulated continuous wave (FMCW) radars are gaining
more and more attraction. One major challenge with the digital signal
processing (DSP) employed in FMCW radars is reducing the number of
required computations in order to achieve a real-time operation. Most
FMCW radars need to continuously perform the Fast Fourier Transform
(FFT) to determine the object range, velocity, etc. This computational
burden is a major obstacle to the radar real-time operation. In this
letter, a computationally efficient FMCW radar is proposed capable of
reducing the number of required FFT operations without sacrificing the
resolution of the estimated range. With careful selection of parameters,
simulations show that the new method can reduce the number of required
FFT operations by a factor of about 119 and 183 in two different
scenarios when compared to a conventional solution.
