Context. The NASA space telescope TESS is currently in the extended mission of its all-sky search for new transiting planets. Of the thousands of candidates that TESS is expected to deliver, transiting planets orbiting nearby M dwarfs are particularly interesting targets since they provide a great opportunity to characterize their atmospheres by transmission spectroscopy.
Aims. We aim to validate and characterize the new sub-Neptune-sized planet candidate TOI-2136.01 orbiting a nearby M dwarf (d = 33.36 ± 0.02pc, Teff = 3373 ± 108 K) with an orbital period of 7.852 days.
Methods. We use TESS data, ground-based multicolor photometry, and radial velocity measurements with the InfraRed Doppler (IRD) instrument on the Subaru Telescope to validate the planetary nature of TOI-2136.01, and estimate the stellar and planetary parameters. We also conduct high-resolution transmission spectroscopy to search for helium in its atmosphere.
Results. We confirm that TOI-2136.01 (now named TOI-2136b) is a bona fide planet with a planetary radius of Rp = 2.20 ± 0.07R⊕ and a mass of Mp = 4.7−2.6+3.1 M⊕. We also search for helium 10830 Å absorption lines and place an upper limit on the equivalent width of <7.8 mÅ and on the absorption signal of <1.44% with 95% confidence.
Conclusions. TOI-2136b is a sub-Neptune transiting a nearby and bright star (J = 10.8 mag), and is a potentially hycean planet, which is a new class of habitable planets with large oceans under a H2-rich atmosphere, making it an excellent target for atmospheric studies to understand the formation, evolution, and habitability of the small planets.
Synthesis of 7-Arylpurines from Substituted Pyrimidines
Authors: Novosjolova Irina , Turks Māris , Sebris Armands 
Published: July 2022

AbstractA simple three-step approach for the synthesis of substituted N7-arylpurines with an overall yield of the whole sequence from 40% to 71% is described. N7-Arylpurines were constructed by de novo synthesis from commercially available substituted 4-chloropyrimidine-5-amines. Different substituents at purine C2 and C6 were obtained by changing the corresponding substituents of the starting pyrimidine. Further, heteroaromatic, electron-deficient, and electron-rich aromatic groups were attached to the exocyclic amino group by iodane reagents under copper catalysis. This moiety is prepared to become purine N7 position after the ring closure. Finally, purine C8 substitution was varied during the last step of the developed sequence by employing different reagents for the purine ring closing reactions or post functionalization.

Published: July 2022

AbstractWe report an amino acid salt-catalyzed direct desymmetrization of 3-substituted cyclobutanones through a direct aldol reaction under mild reaction conditions. The developed method provides an array of highly functionalized cyclobutanones bearing three contiguous stereogenic centers in high yields and stereoselectivities with varied functional-group compatibility. Furthermore, the obtained adducts can be smoothly converted into polyfunctional 1,4-butyrolactones with maintained enantioselectivity.
Solid Primary Retroperitoneal Masses in Adults: An Imaging Approach
Authors: Gulati Vaibhav , Swarup M. Sarthak , Kumar Jyoti 
Published: July 2022

AbstractMass lesions in the retroperitoneal space may be primary or secondary. Primary retroperitoneal mass lesions are relatively uncommon as compared to pathology that arises secondarily from retroperitoneal organs. These may be solid or cystic lesions. The overlapping imaging features of various solid primary retroperitoneal tumors make the diagnosis difficult, and hence, histopathology remains the mainstay of diagnosis. This paper provides a brief review of the anatomy of the retroperitoneal space and provides an algorithmic approach based on cross-sectional imaging techniques to narrow down the differential diagnosis of solid primary retroperitoneal masses encountered in the adult population.
Bilateral Talocalcaneal and Talocalcaneocentral Luxation after a Road Traffic Accident in a Dog
Authors: Serrano-Crehuet Tomas , Espinel-Rupérez Jorge , Amorós Olga , Mullins Ronan A. 
Published: July 2022

AbstractA 4-year-old, 25 kg, male, castrated, crossbreed dog was referred after having been driven over by a trailer 3 days prior. On examination, the dog was unable to ambulate on the pelvic limbs. There was crepitus, soft tissue swelling and pain on manipulation of the tarsi, with bilateral rotational and suspected mild lateral instability. Radiographs identified bilateral talocalcaneal luxation with dorsal displacement of the head of talus and bilateral avulsion fracture of lateral malleolus. A dorsomedial approach to the tarsocrural joint was performed bilaterally and the dorsal luxation of the head of talus was reduced. A 3.5 mm positional cortical screw was placed on both sides from dorsomedial head of talus to plantarolateral distal calcaneus. A temporary calcaneotibial screw was also applied bilaterally. No complications were encountered apart from mild bandage-related dermatitis, and the dog made a complete recovery. No lameness was identified on subjective gait assessment at 14 weeks and 12 months postoperatively; however, mild-to-moderate osteoarthritis affecting the talocalcaneocentral and centrodistal joints was identified at 12 months postoperatively.

AbstractThis article is a response to the commentaries written in reaction to my target article “Cognitive corpus linguistics and pedagogy: From rationale to applications”. It focuses on some issues raised by several commentators: the complexity of applying cognitive corpus linguistics in the language classroom; the question of authenticity in pedagogy; the link between input, intake and output; the place of the teacher and the researcher in applied cognitive corpus linguistics; and possible expansions of the paradigm. It concludes by underlining the importance of exchanges such as those found in this target issue.
Lensing of gravitational waves: universal signatures in the beating pattern
Authors: Bulashenko Oleg , Ubach Helena 
Published: July 2022

Abstract
When gravitational waves propagate near massive objects, their paths curve resulting in gravitational lensing, which is expected to be a promising new instrument in astrophysics.
If the time delay between different paths is comparable with the wave period, lensing may induce beating patterns in the waveform, and it is very close to caustics that these effects are likely to be observable.
Near the caustic, however, the short-wave asymptotics associated with the geometrical optics approximation breaks down. In order to describe properly the crossover from wave optics to geometrical optics regimes, along with the Fresnel number, which is the ratio between the Schwarzschild diameter of the lens and the wavelength, one has to include another parameter — namely, the angular position of the source with respect to the caustic.
By considering the point mass lens model, we show that in the two-dimensional parameter space, the nodal and antinodal lines for the transmission factor closely follow hyperbolas in a wide range of values near the caustic.
This allows us to suggest a simple formula for the onset of geometrical-optics oscillations which relates the Fresnel number with the angular position of the source in units of the Einstein angle.
We find that the mass of the lens can be inferred from the analysis of the interference fringes of a specific lensed waveform.
An efficient approach to solving fractional Van der Pol–Duffing jerk oscillator
Authors: El-Dib Yusry O 
Published: July 2022

Abstract
The motive behind the current work is to perform the solution of the Van der Pol–Duffing jerk oscillator, involving fractional-order by the simplest method. An effective procedure has been introduced for executing the fractional-order by utilizing a new method without the perturbative approach. The approach depends on converting the fractional nonlinear oscillator to a linear oscillator with an integer order. A detailed solving process is given for the obtained oscillator with the traditional system.
Design of readout circuit for high sampling miniaturized MEMS wall shear force sensor
Authors: Guo ZhiJiang , Guo Hui Hui , Liu tingting , Gao Yang 
Published: July 2022

Abstract
Wall shear stress is one of the important measurement parameters in wind tunnel experiments. In the shock wind tunnel, the duration of the flow field is very short, usually a few milliseconds. To ensure measurement accuracy, the sampling rate should not be less than 1kHz. Due to the limitation of model volume and experimental environment, it is necessary to design a miniaturized readout circuit with high precision and high sampling rate, which is highly integrated with the MEMS wall shear stress sensor. The circuit includes a micro capacitance detection module integrated with the sensor head and a host computer signal processing and display module. Aiming at the complex measurement environment of the shock tunnel, to ensure the measurement accuracy, stability, and anti-interference ability of the weak capacitance detection circuit, a miniaturized ceramic substrate circuit is fabricated by a microstrip circuit process. The test results show that the resolution of the micro capacitance of the circuit can reach 20fF at the detection frequency of 3kHz, which can meet the measurement requirements of Shock tunnel, and realize the real-time measurement and display of wall shear stress signal.
An air target association algorithm for infrared sensors
Authors: liu Qing-sheng 
Published: July 2022

Abstract
In order to solve the problem that it is difficult to judge whether the air targets detected by infrared detectors at different locations are the same target, an infrared air target fusion algorithm is proposed. The algorithm constructs a cylindrical coordinate system, introduces two infrared sensors into the cylindrical coordinate system. Then introduces the aerial target information which including azimuth elevation into the cylindrical coordinate system, thus establishing the association between the targets. Finally, the correctness of the algorithm is verified by three rounds of experiments. The simulation results show that the error of the algorithm is within the reservation threshold and has certain engineering application value.
Responses of compound daytime and nighttime warm-dry and warm-humid events to individual anthropogenic forcings

Published: July 2022

Abstract
Daytime heat is often associated with reduced soil moisture and cloud cover, while nighttime heat is connected to high humidity and increased cloud cover. Due to these differing mechanisms, compound daytime and nighttime heat events may respond differently to major anthropogenic forcings (greenhouse gases, anthropogenic aerosols, land-use and land-cover change). Here, we use GISS ModelE2.1-G historical single-forcing runs from 1955 to 2014 to examine how individual anthropogenic forcings affect compound heat events—specifically warm daytime and nighttime temperatures compounded with dry precipitation or high humidity conditions. We show that greenhouse gases alone amplify the natural frequency of warm-dry events by 1.5–5 times and warm-humid events by 2–9 times in tropical and extratropical latitudes. Conversely, aerosols and land-use/land-cover change reduce the frequency of these events, resulting in more modest increases and in some regions, declines, in the historical ‘all-forcings’ scenario. Individually, aerosol effects are stronger and more widespread compared to land-use, oftentimes reducing the natural frequency of these events by 60%–100%. The responses of these compound events are primarily driven by changes in daytime and nighttime temperatures through large-scale warming via greenhouse gases and cooling from aerosols and land-use/land-cover change. However, changes in warm-dry events are amplified in regions with concurrent precipitation declines (e.g. Central America, Mediterranean regions) and warm-humid events are amplified by global concurrent humidity increases. Additionally, we find differences between daytime and nighttime compound responses in the historical experiment that can be traced back to the individual forcings. In particular, aerosols produce a greater cooling effect on daytime relative to nighttime temperatures, which notably results in a historical reduction of Northern Hemisphere daytime warm-dry events relative to natural conditions. Our analysis provides a more comprehensive understanding of the significant impacts of different anthropogenic climate forcings on daytime and nighttime warm-dry and warm-humid events, informing future risk and impact assessments.

Abstract
Wildfire severity is a key indicator of both direct ecosystem impacts and indirect emissions impacts that affect air quality, climate, and public health far beyond the spatial footprint of the flames. Comprehensive, accurate inventories of severity and emissions are essential for assessing these impacts and setting appropriate fire management and health care preparedness strategies, as is the ability to project emissions for future wildfires. The frequency of large wildfires and the magnitude of their impacts have increased in recent decades, fueling concerns about decreased air quality. To improve the availability of accurate fire severity and emissions estimates, we developed the wildfire burn severity and emissions inventory (WBSE). WBSE is a retrospective spatial burn severity and emissions inventory at 30 m resolution for event-based assessment and 500 m resolution for daily emissions calculation. We applied the WBSE framework to calculate burn severity and emissions for historically observed large wildfires (>404 hectares (ha)) that burned during 1984–2020 in the state of California, U.S., a substantially more extended period than existing inventories. We assigned the day of burning and daily emissions for each fire during 2002–2020. The framework described here can also be applied to estimate severity for smaller wildfires and can also be used to estimate emissions for fires simulated in California for future climate and land-use scenarios. The WBSE framework implemented in R and Google Earth Engine can provide quick estimates once a desired fire perimeter is available. The framework developed here could also easily be applied to other regions with user-modified vegetation, fuel data, and emission factors.
No general relation between phase vortices and orbital angular momentum
Authors: Berry M V , Liu Wei 
Published: July 2022

Abstract
Simple superpositions of Laguerre–Gauss beams illustrate, counterintuitively, the difference between two quantities that are commonly conflated: the component of orbital angular momentum ⟨l⟩ in the propagation direction z, and the total topological charge S, which is the algebraic sum of the charges of vortices piercing any plane perpendicular to z. The examples illustrate two contrasting situations: ⟨l⟩ = 0, S ≠ 0, and ⟨l⟩ ≠ 0, S = 0. In the second situation, not only is the total charge zero but also there are no vortices in the infinite half-space beyond the beam waist plane z = 0.

Abstract
Atmospheric pressure hydrolysis without stirring and a combustion–calcination method were utilized to fabricate magnetic Fe3O4/α-Fe2O3 heterogeneous nanorods. First, the β-FeOOH nanorods were fabricated via hydrolysis, and the concentration of Fe3+, hydrolysis temperature, and hydrolysis time were optimized. The optimal fabrication conditions were as follows: a 0.1 M FeCl3 solution was hydrolyzed at 90 °C for 2 h. The average length and diameter of the β-FeOOH nanorods fabricated under the optimal conditions were approximately 216 and 58 nm, respectively. Subsequently, Fe3O4/α-Fe2O3 heterogeneous nanorods were fabricated via a combustion–calcination process. The volume of absolute ethanol, calcination temperature, and calcination time were investigated to optimize the fabrication conditions of Fe3O4/α-Fe2O3 heterogeneous nanorods under the following conditions: absolute ethanol: 50 ml; calcination temperature: 300 °C; and calcination time: 2 h. Magnetic Fe3O4/α-Fe2O3 heterogeneous nanorods fabricated under optimal conditions were characterized with an average length of 199 nm, an average diameter of 51 nm, a zeta potential of +17.2 mV, and a saturation magnetization of 13 emu·g–1.

Abstract

Background
Peer support provides varied health benefits, but how it achieves these benefits is not well understood.

Purpose
Examine a) predictors of participation in peer support interventions for diabetes management, and b) relationship between participation and glycemic control.

Methods
Seven peer support interventions funded through Peers for Progress provided pre/post data on 1,746 participants’ glycemic control (hemoglobin A1c), contacts with peer supporters as an indicator of participation, health literacy, availability/satisfaction with support for diabetes management from family and clinical team, quality of life (EQ-Index), diabetes distress, depression (PHQ-8), BMI, gender, age, education, and years with diabetes.

Results
Structural equation modeling indicated a) lower levels of available support for diabetes management, higher depression scores, and older age predicted more contacts with peer supporters, and b) more contacts predicted lower levels of final HbA1c as did lower baseline levels of BMI and diabetes distress and fewer years living with diabetes. Parallel effects of contacts on HbA1c, although not statistically significant, were observed among those with baseline HbA1c values &gt; 7.5% or &gt; 9%. Additionally, no, low, moderate, and high contacts showed a significant linear, dose–response relationship with final HbA1c. Baseline and covariate-adjusted, final HbA1c was 8.18% versus 7.86% for those with no versus high contacts.

Conclusions
Peer support reached/benefitted those at greater disadvantage. Less social support for dealing with diabetes and higher PHQ-8 scores predicted greater participation in peer support. Participation in turn predicted lower HbA1c across levels of baseline HbA1c, and in a dose–response relationship across levels of participation.
Dynamics of microbiota in the imported beef primal cuts during storage at different chilled temperatures
Authors: Nakamura Ayaka , Mizuno Yuri , Takahashi Hajime , Otomo Kota , Kuda Takashi , Kimura Bon 
Published: July 2022

ABSTRACT
Primal cuts of Australian beef transported by sea were stored under different chilled temperatures (0, 2, and 4 °C) for 6 weeks in different packaging conditions (aerobic or anaerobic packaging). The number of microorganisms and the transition of the microbiota were investigated using culture methods and amplicon sequencing. After 6 weeks of storage, the beef tended to show a high total viable count under aerobic packaging conditions and a high lactic acid bacteria count under anaerobic packaging conditions. The result of amplicon sequencing analysis showed that different beef samples had different predominant bacterial groups. Moreover, at high storage temperatures, Serratia sp. having high putrefactive activity showed increased abundance, while at low storage temperatures, Lactobacillus sp. showed increased abundance. Thus, differences in the packaging conditions and distribution temperatures after import affect the number of bacteria and the type of microorganisms in the Australian beef primal cuts, which may affect their quality.
