Published: March 2022

O b j e c t i v e s . In radar systems for moving objects tracking, there are often gaps in the measurement of coordinates.The problem is mostly fully solved in continuous time in the theory of systems with a random structure within the framework of statistical Bayesian theory of filtration in the presence of complete a priori statistical information. This approach leads to complex algorithms that are difficult to implement in practice. The purpose of investigation was to develop a filtering algorithm in conditions of information interruptions based on the use of extended least squares method.M e t h o d s . Methods of estimation theory are used, in particular, the extended least squares method, which makes it possible to find relatively simple algorithms with a minimum amount of a priori knowledge about the characteristics of the impacts.R e s u l t s . The algorithm for filtering radar signals has been developed, based on measurements of the moments of breaks and extrapolation of the measured coordinates at intervals of information lack. The resulting algorithm is nonlinear and therefore tracking disruptions may occur in the filter. The results of the algorithm are demonstrated using a model example. The estimation of the filtering accuracy and tracking failure conditions is carried out.Co n c l u s i o n . A filtering algorithm has been developed that allows determining the moments of the onset of breaks and extrapolating the estimates of useful information. The comparative simplicity of the algorithm makes it suitable for practical use.
N-body Interactions will be Detectable in the HR-8799 System within 5 yr with VLTI-GRAVITY

Abstract
While Keplerian orbits account for the majority of the astrometric motion of directly-imaged planets, perturbations due to N-body interactions allow us to directly constrain exoplanet masses in multiplanet systems. This has the potential to improve our understanding of massive directly-imaged planets, which nearly all currently have only model-dependent masses. The VLTI-GRAVITY instrument has demonstrated that interferometry can achieve 100x better astrometric precision than existing methods, a level of precision that makes detection of planet–planet interactions possible. In this study, we show that in the HR-8799 system, planet–planet deviations from currently used Keplerian approximations are expected to be up to one-quarter of a milliarcsecond within five years, which will make them detectable with VLTI-GRAVITY. Modeling of this system to directly constrain exoplanet masses will be crucial in order to make precise predictions.

Abstract
Immaturity of alveolar macrophages (AMs) around birth contributes to the susceptibility of newborns to lung disease. However, the molecular features differentiating neonatal and mature, adult AMs are poorly understood. In this study, we identify the unique transcriptomes and enhancer landscapes of neonatal and adult AMs in mice. Although the core AM signature was similar, murine adult AMs expressed higher levels of genes involved in lipid metabolism, whereas neonatal AMs expressed a largely proinflammatory gene profile. Open enhancer regions identified by an assay for transposase-accessible chromatin followed by high-throughput sequencing (ATAC-seq) contained motifs for nuclear receptors, MITF, and STAT in adult AMs and AP-1 and NF-κB in neonatal AMs. Intranasal LPS activated a similar innate immune response in both neonatal and adult mice, with higher basal expression of inflammatory genes in neonates. The lung microenvironment drove many of the distinguishing gene expression and open chromatin characteristics of neonatal and adult AMs. Neonatal mouse AMs retained high expression of some proinflammatory genes, suggesting that the differences in neonatal AMs result from both inherent cell properties and environmental influences.

Published: March 2022

ABSTRACT

Background:
Male infertility account for nearly 50% of infertility cases. Cadmium is regarded as a well-known toxic metal for industrial applications; high amounts of cadmium in the human body can result in chronic toxicity. Melatonin as a free radical scavenger has anti-inflammatory, and even anti-cancer and antiapoptotic functions.

Aim:
In this work, we evaluated the protective effect of melatonin on human sperm parameters treated by cadmium.

Study Setting and Design:
This was an experimental study carried out from May to December 2019.

Materials and Methods:
A total of 41 fresh semen samples were collected from fertile men and were divided into 4 groups: (1) control, (2) sperm +25 Nm cd, (3) sperm +25 nM cd +0.1 mM melatonin,(4) sperm +0.1 mM melatonin treated for 60 min. In all groups, semen analysis was performed for motility, viability and DNA fragmentation index (DFI).

Statistical Analysis:
The groups were compared using the ANOVA test.

Results:
The group treated with cadmium showed a significant decrease in rapid and slow motility, and survival rate compared with the control group (P < 0.05). However, the degree of DFI and sperm with non-progressive motility in the group treated with cadmium had a significant increase compared to the control (P < 0.05). The use of melatonin significantly improved sperm parameters such as motility, survival rate and decreased sperm DFI with non-progressive motility.

Conclusions:
The use of melatonin reduces the amount of cadmium damage in human sperm in vitro.

The Southern African Lepidoptera Conservation Assessment (SALCA) was a collaborative venture between the Lepidopterists’ Society of Africa (LepSoc Africa), the Brenton Blue Trust (BBT) and the South African National Biodiversity Institute (SANBI), and formed part of the National Biodiversity Assessment (NBA). SALCA was founded on the importance of Lepidoptera both ecologically and as biodiversity indicators and the proven expertise of the participants during the Southern African Butterfly Conservation Assessment (SABCA). The main outcomes of the SALCA project are presented and discussed here.The SALCA tool, a custom-designed interactive distribution database, enabled high quality data to be derived so that accurate conservation assessments could be produced in accordance with IUCN methodology. The Red Lists of SALCA and SABCA facilitated the first opportunity to calculate the Red List Index (RLI) for South African butterflies during the period from 2012–2018. Other metrics required for the NBA included protection level and threats analyses. A further outcome was the critical habitat mapping for butterflies, which formed part of a screening tool implemented by SANBI, to ensure that land use changes did not cause any further loss of butterfly biodiversity.A comprehensive distribution database was developed for South African moths, enabling data to be analysed so that moth species potentially threatened could be short-listed for further investigation.Geographical hotspots and ecosystems (vegetation types) containing butterflies of conservation concern are highlighted. The societal, economic and human wellbeing benefits of conserving Lepidoptera are identified. Responses by LepSoc Africa to the increasing pressures on South African Lepidoptera biodiversity, are also reported on and discussed. The significant outcomes of SABCA and SALCA are benchmarked against a well-known European butterfly atlasing and conservation assessment project.The 165 SALCA Red Lists and conservation assessments are presented at the end of this publication.

•	Commercial papers are one of the most significant means of the contemporary money market and many of those dealing with them are actually ignorant of Sharia related rulings. Hence the urgent need to get acquainted with the most prominent Shariah rulings related to commercial papers, including the discount is an agreement between the bank and its customer (the holder of the commercial paper), by which the bank is abided by to accelerate the value of the paper to the customer, in return , the latter’s obligation should transfer the ownership of the fixed right in the paper to the bank by endorsing it to him as a transfer of ownership. The bank discount amount of money from the value of the commercial paper called the price of discount in return for an interest paid for the period from the date of its pay up to the due date of the paper. •	The noble Islamic Sharia does not prohibit dealing with the commercial papers in principle, but on the contrary. It establishes principle of writing and fixing debts in certain formal papers and documents, but nevertheless, this Sharia prohibits the process of discounting commercial papers, whatever its form, either be commission, interest or wages, because it leads to the realization of usury. In this research, we will shed light on the definition of the commercial paper discount and its types, what the discount is subject to and its returns, then the sharia position of the discount process and trends of some jurists in finding jurisprudential exits for the permissibility of commercial papers discount and legitimate alternative to commercial papers discount.
Biomarker proxy records of Arctic climate change during the Mid-Pleistocene transition from Lake El'gygytgyn (Far East Russia)
Authors: Lindberg Kurt R. , Daniels William C. , Castañeda Isla S. , Brigham-Grette Julie 
Published: March 2022

Abstract. The Mid-Pleistocene Transition (MPT) is a widely recognized global
climate shift occurring between approximately 1250 and 700 ka. At this time, Earth's climate underwent a major transition from dominant 40 kyr
glacial–interglacial cycles to quasi-100 kyr cycles. The cause of the MPT
remains a puzzling aspect of Pleistocene climate. Presently, there are few,
if any, continuous MPT records from the Arctic, yet understanding the role
and response of the high latitudes to the MPT is required to better evaluate
the causes of this climatic shift. Here, we present new continental
biomarker records of temperature and vegetation spanning 1142 to 752 ka
from Lake El'gygytgyn (Far East Russia). We reconstruct warm-season
temperature variations across the MPT based on branched glycerol dialkyl
glycerol tetraethers (brGDGTs). The new Arctic
temperature record does not display an overall cooling trend during the MPT
but does exhibit strong glacial–interglacial cyclicity. Spectral analysis
demonstrates persistent obliquity and precession pacing over the study
interval and reveals substantial sub-orbital temperature variations at
∼900 ka during the first “skipped” interglacial.
Interestingly, Marine Isotope Stage (MIS) 31, which is widely recognized as
a particularly warm interglacial, does not exhibit exceptional warmth in the
Lake El'gygytgyn brGDGT record. Instead, we find that MIS 29, 27, and 21 were as warm or warmer than MIS 31. In particular, MIS 21 (∼870 to
820 ka) stands out as an especially warm and long interglacial in the
continental Arctic while MIS 25 is a notably cold interglacial. Throughout
the MPT, Lake El'gygytgyn pollen data exhibit a long-term drying trend, with
a shift to an increasingly open landscape noted after around 900 ka (Zhao
et al., 2018), which is also reflected in our higher plant leaf wax
(n-alkane) distributions. Although the mechanisms driving the MPT remain a matter of debate, our new climate records from the continental Arctic
exhibit some similarities to changes noted around the North Pacific region.
Overall, the new organic geochemical data from Lake El'gygytgyn contribute
to expanding our knowledge of the high-latitude response to the MPT.
Arctic glaciers and ice caps through the Holocene:a circumpolar synthesis of lake-based reconstructions
Authors: Larocca Laura J. , Axford Yarrow 
Published: March 2022

Abstract. The recent retreat of nearly all glaciers and ice caps (GICs)
located in Arctic regions is one of the most clear and visible signs of
ongoing climate change. This paper synthesizes published records of Holocene
GIC fluctuations from lake archives, placing their recent retreat into a
longer-term context. Our compilation includes 66 lake-based GIC
records (plus one non-lake-based record from the Russian Arctic) from
seven Arctic regions: Alaska, Baffin Island in northeastern Canada,
Greenland, Iceland, the Scandinavian peninsula,
Svalbard, and the Russian high Arctic. For each region and for the full
Arctic, we summarize evidence for when GICs were smaller than today or
absent altogether, indicating warmer-than-present summers, and evidence for
when GICs regrew in lake catchments, indicating summer cooling. Consistent
with orbitally driven high boreal summer insolation in the early Holocene,
the full Arctic compilation suggests that the majority (50 % or more) of
studied GICs were smaller than present or absent by ∼10 ka.
We find the highest percentage (>90 %) of Arctic GICs smaller
than present or absent in the middle Holocene at ∼ 7–6 ka,
probably reflecting more spatially ubiquitous and consistent summer warmth
during this period than in the early Holocene. Following this interval of
widespread warmth, our compilation shows that GICs across the Arctic began
to regrow and summers began to cool by ∼6 ka. Together, the
Arctic records also suggest two periods of enhanced GIC growth in the
middle to late Holocene from ∼ 4.5–3 and after ∼2 ka. The regional records show variability in the timing of
GIC regrowth within and between regions, suggesting that the Arctic did not
cool synchronously despite the smooth and hemispherically symmetric decline
in Northern Hemisphere summer insolation. In agreement with other studies,
this implies a combined response to glacier-specific characteristics such
as topography and to other climatic forcings and feedback mechanisms,
perhaps driving periods of increased regional cooling. Today, the direction
of orbital forcing continues to favor GIC expansion; however, the rapid
retreat of nearly all Arctic GICs underscores the current dominance of
anthropogenic forcing on GIC mass balance. Our review finds that in the
first half of the Holocene, most of the Arctic's small GICs became
significantly reduced or melted away completely in response to summer
temperatures that, on average, were only moderately warmer than today. In
comparison, future projections of temperature change in the Arctic far
exceed estimated early Holocene values in most locations, portending the
eventual loss of most of the Arctic's small GICs.

ABSTRAKPerkembangan Kota pada kawasan terbagun di Kota Kendari salah satunya adalah kawasan Andounohu yang memiliki pontesi permasalahan transportasi, yaitu munculnya pusat pusat kegitan sehingga pergerakan mobilitas penduduk yang tinggi. Kawasan pasar Andounohu sangat rentan dengan permasalahan parkir dalam hal ini belum tersedianya peruntukan lahan dan penataan parkir sehingga sangat memprihatinkan pengguna transportasi baik jangka pendek, menengah maupun jangka panjang. Penelitian ini bertujuan untuk memberikan alternaif penanganan parkir dengan model parkir disisi jalan Kedondong kawasan pasar Andounohu di Kota Kendari. Hasil penelitian ruas jalan Kedondong dengan tanpa hambatan samping mengalami penuruanan koefisien serta mengalami perubahan tingkat pelayanan dengan koefisien sebesar 0,40. Untuk perencanaan penataan parkir di ruas jalan Kedondong dengan kondisi geometrik lebar lajur 3.00 meter dan ditambah dengan lebar penataan parkir di badan jalan sebesar 1,20 meter dan bahu sebesar 1,0 meter, sehingga untuk lebar badan jalan efektif 2 lajur 2 arah yaitu 6,0 meter. Hasil analisis model regresi linier dapat diketahui bahwa hambatan samping yang berpengaruh terhadap kinerja lalulintas yaitu terjadi pada hambatan samping waktu sibuk sore dengan koefisien determinasi (R2) tertinggi sebesar 0,852. Dengan menggunakan persamaan Y = 0,259 + 0,001 X. Kata Kunci : Model, On-street parking, Hambatan sampingABSTRACTUrban of one the developments in the built area in Kendari is the Andounohu area which has the potential for transportation problems, namely the emergence of a center of activity so that the movement of population mobility is high. Andounohu market area is very the vulnerable to parking problems, in this case the unavailability of land allotment and parking arrangement so that it is very concerning for short, medium and long term transportation users. This study aims to provide an alternative parking handling with a parking model on the side of Jalan Kedondong, Andounohu market area in Kendari city. Kedondong road the section without side obstacles experienced a decrease in coefficient and experienced changes in service levels with a coefficient of 0.40. For the parking arrangement planning on Kedondong road with geometric conditions, the lane width is 3.00 meters and the width of the parking arrangement on the road is 1.20 meters and the shoulders are 1.0 meters, so that the effective width of the road is 2 lanes 2 directions, namely 6, 0 meters.
