Preliminary report on the landslide early warning on August 20, 2021, in Nangqian County, Qinghai Province, China
Authors: Wang Xiangpeng , Wang Kunpeng , Lin Fanqiang , Guo Kai 
Published: June 2022

AbstractBased on an analysis of the formation mechanism, stability state and development trend, this paper focuses on monitoring key indicators, such as surface deformation and rainfall, to realize the early warning of landslides and provide some guidance for landslide disaster prevention and avoidance in the alpine mountainous area of Nangqian, Qinghai Province. The landslide of the Baima Elin Monastery has the topographic and geomorphological conditions of landslide formation and has the basic characteristics indicating that it can be influenced by rainfall and climate, so a landslide warning should be comprehensive. At the same time, the landslide is currently in an unstable state, and the seasonal freeze–thaw cycle will cause it to become more unstable. Based on macroscopic signs, it is predicted that the deformation of the Baima Elin Monastery landslide will continue to intensify without abatement, the stability will be further reduced after winter, developing in an unfavorable direction, and engineering measures should be taken as soon as possible to manage the landslide.

atomic medium by varying the spontaneously generated coherence (SGC). Magnetic field and strong coupling field are applied to the atomic configuration. The light-matter interaction leads to enhanced the magneto-optical rotation. The intensity of the applied fields plays promising role in the generation and enhancement of birefringence. It ultimately enhances the polarization plane rotation of the probe beam in the Doppler medium. In the presence of both SGC and Doppler broadening effects, the optical rotation and transmission of the weak light beam are modified and controlled as well, which have potential applications in magnetometery and laser frequency stabilization.

AbstractThe present work focuses on investigating the effect of non-fluoro short-chain alkylsilane treatment on the surface characteristic of date palm (Phoenix dactylifera) fiber. Raw date palm fiber (DPF) was treated with octylsilane and the surface properties of treated fiber was investigated using thermogravimetric analysis (TGA), fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), contact angle analysis and X-ray diffraction (XRD) on configuring the thermal stability, chemical structures and surface properties (morphology, hydrophobicity and crystallinity). The decomposition temperature of 75% mass loss raw and treated DPF, the onset of temperatures were increased from 464 to 560 °C with the introduction of alkylsilane. Hydrophobicity and crystallinity index of the DPF fibers were increased from 66.8° to 116° and 31 to 41, introducing octylsilane to raw DPF. The SEM and XRD experimental results showed that the octylsilane treatment could effectively increase the pore size and crystallinity index as an indication of the removal of non-crystalline cellulosic materials from DPFs. Thermal stability, hydrophobicity and crystallinity of the fibers increased on DFP after alkylsilane treatment. The results indicated that alkylsilane-treated DPFs were a suitable reinforcing substitute for hydrophobic polymer composite.
Safety assessment and sustainability of consuming eggplant (Solanum melongena L.) grown in wastewater-contaminated agricultural soils
Authors: Alamer Khalid H. , Galal Tarek M. 
Published: June 2022

AbstractVegetables cultivated on contaminated agricultural soils are being consumed by the public, and consequently cause serious health concerns due to contaminants' dietary intake. The current study examines the safety and sustainability of eating eggplant (Solanum melongena) by looking into the possibility of heavy metals translocation from polluted soils to the edible sections, as well as the health hazards that come with it. Soil and eggplant samples were taken from three contaminated and other three uncontaminated farms to estimate their chemical constituents and plant growth properties. Based on the pollution load index data, the contaminated soils were highly polluted with Fe, Cu, Pb, and Zn; and relatively polluted with Cr, Mn, Cd, Mn, Co, and V. Under contamination stress, the fresh biomass, dry biomass, and production of eggplant were significantly reduced by 41.2, 44.6, and 52.1%, respectively. Likewise, chlorophyll a and b were significantly reduced from 1.51 to 0.69 mg g−1 and 1.36 to 0.64 mg g−1, respectively. The uncontaminated plant shoots had the highest quantities of N, P, and proteins (1.98, 2.08, and 12.40%, respectively), while the roots of the same plants had the highest K content (44.70 mg kg−1). Because eggplant maintained most tested heavy elements (excluding Zn and Pb) in the root, it is a good candidate for these metals' phytostabilization. However, it had the potential to translocate Mn and Zn to its shoot and Pb, Cr, Mn, and Zn to the edible fruits indicating its possibility to be a phytoextractor and accumulator of these metals. Cd, Cu, Ni, Pb, Mn, and Co quantity in the edible sections of eggplant grown in contaminated soils exceeded the permissible level for normal plants, posing health hazards to adults and children. For safety issues and food sustainability, our investigation strongly recommends avoiding, possibly, the cultivation of eggplant in contaminated agricultural lands due to their toxic effects even in the long run.
Energy Materials Discovery

Published: June 2022

Materials have the potential to be the centrepiece for the transition to viable renewable energy technologies if they realise a specific suite of properties and achieve a desired set of performance metrics. The envisioned transition involves the discovery of materials that enable generation, conversion, storage, transmission, and utilization of renewable energy.
This book presents, through the eye of materials chemistry, an umbrella view of the myriad of classes of materials that make renewable energy technologies work. They are poised to facilitate the transition of non-renewable and unsustainable energy systems of the past into renewable and sustainable energy systems of the future. It is a story that often begins in chemistry laboratories with the discovery of new energy materials. Yet, to displace materials in existing energy technologies with new ones, depends not only on the ability to design and engineer a superior set of performance metrics for the material and the technology but also the requirement to meet a demanding collection of economic, regulatory, social, policy, environmental and sustainability criteria.
Disruption in the traditional way of discovering materials is coming with the emergence of artificial intelligence, machine learning and robotic automation designed to accelerate the well-established discovery process, massive libraries of materials can be evaluated and the possibilities are endless. This book provides a perspective on the application of these new technologies to this field as well as an overview of energy materials discovery in the broader techno-economic and social context. Any budding researcher or more experienced materials scientist will find a guide to a fascinating story of discovery and emerge with a vision of what is next.

A Multidimensional Approach for School-Aged Children who Stutter
Authors: Caughter Sarah , Kelman Elaine , Delpeche Sarah 
Published: June 2022

AbstractTherapy for school-aged children who stutter (CWS) and their parents should be holistic, individualized, and multidimensional, considering the child within their real-life context and using a solution rather than problem-focused approach; highlighting and drawing on the strengths, resources, values; and coping skills that each family brings. Therapy at the Michael Palin Centre draws on a number of psychological approaches, including solution-focused brief therapy, cognitive behavior therapy, acceptance and commitment therapy, and compassion-focused therapy. Aspects of these approaches are discussed in this article to describe the therapeutic intervention for two school-aged CWS (aged 8 and 15 years). The Palin Model (2019) is used to conceptualize the factors that influence stuttering, as well as the different components of therapy that may be relevant for each individual family. The overarching aim of therapy, for children to become competent and effective communicators, whether they stutter or not, is described through a range of practical therapeutic activities, including exploring communication skills, openness and desensitization, exploring thoughts and feelings around stuttering, building confidence, expanding comfort zones, and developing self-efficacy. Qualitative and quantitative outcomes are presented for each clinical case.

Published: June 2022

AbstractLexipontix is a structured therapy program for school-age children who stutter. It is based on theoretical principles and clinical practices of cognitive behavioral therapy, parent–child interaction therapy, solution-focused brief therapy, fluency shaping, and stuttering modification. A case example of a school-age child who stutters and his family who participated in the Lexipontix program is illustrated to highlight the theoretical principles, structure, content, and clinical tools of the assessment and therapy process of the program. The Lexipontix program addresses the stuttering experience of the child and family in a holistic way. The child and family are assisted in facilitating changes in all components of the International Classification of Functioning, Disability, and Health model (i.e., body function, personal factors, activity and participation, environmental factors), which help them move toward their “best hopes” (i.e., personally meaningful change) from therapy. The role of the clinician in facilitating change is also considered. Therapy outcomes for the specific case example are presented and discussed in relation to data from a retrospective chart review. The mechanisms underlying the effectiveness of the program are explored and discussed.

Abstract
Background Little is written on how best to structure IT governance in health care organizations. Governance is challenging because these groups may contain administrators, clinicians, and staff in addition to IT employees; projects may be complex and have significant impact on the teams that provide patient care.
Methods Peer organizations in health care were purposefully selected and C-suite executives were interviewed about their IT governance. Notes taken from these conversations were analyzed for guiding principles.
Results We interviewed leaders from five peer organizations. Consensus principles included: (1) minimize unwarranted variation; (2) evolve governance with the organization but independently of projects; (3) govern all clinical applications; (4) be flexible with intake, yet clear on decision-making; (5) have a tiered approach to governance; and (6) be multidisciplinary. Emerging principles included: (1) assign an IT business relationship manager to each high priority initiative, (2) have a clear escalation path to a small number of decision-makers, (3) include analytics to inform governance, (4) leverage Informatics expertise, and (5) use structured tools to streamline the process.
Conclusion While IT governance is very different across distinct health care organizations, there are some general principles that many share.

Published: June 2022

AbstractFat necrosis is a common complication of breast surgery, with the potential to cause both functional and aesthetic repercussions that can affect patient satisfaction. Although several fat necrosis classification systems have been proposed, fat necrosis management varies widely across institutions, requiring revisiting of existing treatment protocols. We evaluated the postoperative outcomes on 335 breasts following either breast reduction or reconstruction with deep inferior epigastric perforator (DIEP) flaps at our institution between 2016 and 2020, with particular attention to the development of fat necrosis and the need for subsequent surgical intervention. Fat necrosis was diagnosed in 36 (10.74%) breasts, of which 16 (44.4%) were surgically removed and 20 (55.5%) were conservatively managed. Time of fat necrosis diagnosis: early (≤one-month after breast surgery) or late (>1 month) was the only variable associated with surgical intervention. Fat necrosis management should be approached on a case-by-case basis. Whenever possible, conservative management with regular clinical and radiological follow-up, and patient reassurance, should be pursued even for large masses, in the absence of concomitant complications.

Published: June 2022

The first measurement of the photoelectron spectrum of the silylidyne free radical, SiH, is reported between 7 and 10.5 eV. Two main photoionizing transitions involving the neutral ground state, X+1Σ+ ← X2Π and a+3Π ← X2Π, are assigned by using ab initio calculations. The corresponding adiabatic ionization energies are derived, IEad(X+1Σ+) = 7.934(5) eV and IEad(a+3Π) = 10.205(5) eV, in good agreement with our calculated values and the previous determination by Berkowitz et al. [J. Chem. Phys. 86, 1235 (1987)] from a photoionization mass spectrometric study. The photoion yield of SiH recorded in this work exhibits a dense autoionization landscape similar to that observed in the case of the CH free radical [Gans et al., J. Chem. Phys. 144, 204307 (2016)].
Benchmarking CASPT3 vertical excitation energies
Authors: Boggio-Pasqua Martial , Jacquemin Denis , Loos Pierre-François 
Published: June 2022

Based on 280 reference vertical transition energies of various excited states (singlet, triplet, valence, Rydberg, n → π*, π → π*, and double excitations) extracted from the QUEST database, we assess the accuracy of complete-active-space third-order perturbation theory (CASPT3), in the context of molecular excited states. When one applies the disputable ionization-potential-electron-affinity (IPEA) shift, we show that CASPT3 provides a similar accuracy as its second-order counterpart, CASPT2, with the same mean absolute error of 0.11 eV. However, as already reported, we also observe that the accuracy of CASPT3 is almost insensitive to the IPEA shift, irrespective of the transition type and system size, with a small reduction in the mean absolute error to 0.09 eV when the IPEA shift is switched off.
Spectroscopic valuation of phonon lifetime and surface characteristics of Zn0.96Mg0.04S thin film
Authors: Krishna V S Ganesha , Mahesha M. G. 
Published: June 2022

The anharmonic properties of the longitudinal optical (LO) phonon mode of Mg-doped ZnS (Zn0.96 Mg0.04S) are investigated using the Balkanski and Klemens models on the temperature-dependent Raman spectra. The variation in the position of the Raman line, peak width, and phonon lifetime with temperature was fitted using three and four phonon decay mechanisms. The values of the anharmonic fitting parameters indicated low anharmonicity. A lifetime of ∼0.17 ps at 90 K indicated a fast phonon decay. In addition, the thin film is analyzed to evaluate its surface characteristics using Raman mapping that showed chemical homogeneity over a large area of the film. Furthermore, we analyzed spatial variations of Raman line intensity, peak area, linewidth, and line position of the LO phonon mode. Raman analysis helped in understanding the phonon–phonon interaction mechanism in Zn0.96 Mg0.04S thin films.

Published: June 2022

A new heteronuclear decoupling pulse sequence is introduced, dubbed ROtor-Synchronized Phase-Alternated Cycles (ROSPAC). It is based on a partial refocusing of the coherences (spin operator products or cross-terms) [Filip et al., J. Mag. Reson. 176, 2 (2005)] responsible for transverse spin-polarization dephasing, on the irradiation of a large pattern of radio-frequencies, and on a significant minimization of the cross-effects implying 1H chemical-shift anisotropy. Decoupling efficiency is analyzed by numerical simulations and experiments and compared to that of established decoupling sequences [swept-frequency two-pulse phase-modulated (TPPM), TPPM, small phase incremental alternation (SPINAL), refocused Continuous-wave (CWApa), and Rotor-Synchronized Hahn-Echo pulse train (RS-HEPT)]. It was found that ROSPAC offers good 1H offset robustness for a large range of chemical shifts and low radio-frequency (RF) powers, and performs very well in the ultra-fast magic-angle spinning (MAS) regime, where it is almost independent from RF power and permits it to avoid rotary-resonance recoupling conditions (v1 = nvr, n = 1, 2). It has the advantage that only the pulse lengths require optimization and has a low duty cycle in the pulsed decoupling regime. The efficiency of the decoupling sequence is demonstrated on a model microcrystalline sample of the model protein domain GB1 at 100 kHz MAS at 18.8 T.

Published: June 2022

Water deficit is the most critical factor limiting plant growth and production and salicylic acid (SA) has potential for stress mitigation in plants; therefore, we evaluated the effect of SA on radish (Raphanus sativus L.) growth and ecophysiology under water deficit. Plants were sprayed with SA (100 μM) or water (control), and irrigated at 80% (W80), 60% (W60), 40% (W40), and 20% (W20) of field capacity. The SA treatments and drought stress started 7 days after sowing and lasted until the end of the cycle (30 days after sowing). The morphophysiological analyses showed that radish plants had impaired growth at the lower water supply levels, but the treatment with SA reversed these growth restraints under moderate stress, leading to increases in shoot mass at W40 and storage root mass at W60 and W40. SA treatment also reversed the reduction of storage root volume at W60. The tendency of water deficit to increase FO and reduce FV/FM suggests possible damage to the photosystem II of drought-stressed plants. The parameters of gas exchange and photosynthetic pigments showed maintained photosynthetic efficiency, but total photosynthesis decreased due the lower shoot dry mass. Overall, exogenously applied SA reversed the growth restraints at W60 and W40, which revealed that SA was effective in mitigating the effects of moderate water deficit on biomass accumulation and partitioning in radish plants.
Indole-3-pyruvic acid regulates TAA1 activity, which plays a key role in coordinating the two steps of auxin biosynthesis

Published: June 2022

Auxin biosynthesis involves two types of enzymes: the Trp aminotransferases (TAA/TARs) and the flavin monooxygenases (YUCCAs). This two-step pathway is highly conserved throughout the plant kingdom and is essential for almost all of the major developmental processes. Despite their importance, it is unclear how these enzymes are regulated and how their activities are coordinated. Here, we show that TAA1/TARs are regulated by their product indole-3-pyruvic acid (IPyA) (or its mimic KOK2099) via negative feedback regulation in
Arabidopsis thaliana
. This regulatory system also functions in rice and tomato. This negative feedback regulation appears to be achieved by both the reversibility of Trp aminotransferase activity and the competitive inhibition of TAA1 activity by IPyA. The
K
m
value of IPyA is 0.7 µM, and that of Trp is 43.6 µM; this allows IPyA to be maintained at low levels and prevents unfavorable nonenzymatic indole-3-acetic acid (IAA) formation from IPyA in vivo. Thus, IPyA levels are maintained by the push (by TAA1/TARs) and pull (by YUCCAs) of the two biosynthetic enzymes, in which TAA1 plays a key role in preventing the over- or under-accumulation of IPyA. TAA1 prefer Ala among various amino acid substrates in the reverse reaction of auxin biosynthesis, allowing TAA1 to show specificity for converting Trp and pyruvate to IPyA and Ala, and the reverse reaction.
