Significance
Studies have shown that long-term damages from unmitigated climate change are greater than the mitigation costs worldwide, but costs greatly exceed climate benefits in the near term, undermining action now. Emissions reductions affect more than just climate, however. We show that near-term US benefits of decarbonization are dominated by improved air quality for human health, labor productivity, and agriculture whereas climate-related benefits are realized largely after 2050. Additionally, using recent health research, we show that health benefits of both clean air and reduced climate change are far larger than previously estimated. Considering these additional benefits of emissions reductions, benefits outweigh costs even in the near term. Near-term benefits stem primarily from US actions, whereas long-term climate-related benefits require global cooperation.
Extension request avoidance predicts greater time stress among women

Published: November 2021

Significance
Time stress—the feeling of having too many things to do and not enough time to do them—is a societal epidemic that compromises productivity, physical health, and emotional well-being. Past research shows that women experience disproportionately greater time stress than men and has illuminated a variety of contributing factors. Across nine studies, we identify a previously unexplored predictor of this gender difference. Women avoid asking for more time to complete work tasks, even when deadlines are explicitly adjustable, undermining their well-being and task performance. We shed light on a possible solution: the implementation of formal policies to facilitate deadline extension requests. These findings advance our understanding of the gendered experience of time stress and provide a scalable organizational intervention.

Significance
Plastic waste accumulating in the world's oceans forms massive “plastic islands” in the oceanic gyres. Removing the plastic offers an opportunity to restore our oceans to a more pristine state. To clean the gyres, ships must collect and store the plastic before transporting it to port, often thousands of kilometers away. Instead, ocean plastic waste can be converted into fuel shipboard, for example, using hydrothermal liquefaction (HTL), which depolymerizes plastics at high temperature (300 °C to 550 °C) and high pressure (250 bar to 300 bar). The resulting depolymerization products, termed “blue diesel,” have the potential for self-powered cleanup. The objective of this work is evaluating the thermodynamic feasibility of this scheme and its implications on cleanup.
Stable lariats bearing a snoRNA (slb-snoRNA) in eukaryotic cells: A level of regulation for guide RNAs
Authors: Talross Gaëlle J. S. , Deryusheva Svetlana , Gall Joseph G. 
Published: November 2021

Significance
Small nucleolar (sno)RNAs generally guide ribosomal RNA and small nuclear RNA modifications, essential events for ribosome and spliceosome biogenesis and function. Most are processed in the nucleus from lariat intronic RNAs, which are unstable byproducts of splicing. We report here that some snoRNAs are encoded within unusually stable lariats. These stable lariats bearing a snoRNA (or slb-snoRNAs) can be found in the nucleus and cytoplasm associated with snoRNA binding proteins. They do not function as modification guide RNAs and their export competes with snoRNA maturation. Therefore, slb-snoRNAs provide a new level of regulation of snoRNAs and snoRNA binding proteins.
Investigation of a method for online measurement of injection rate for a high-pressure common rail diesel engine injector under multiple-injection strategies
Authors: Yang Xiyu , Dong Quan , Song Jingdong , Zhou Tanqing 
Published: November 2021

Abstract
As a state-of-the-art injection technology, the high-pressure common rail injection system (HPCRIS) has advantages that include high injection pressure, adjustable injection timing and a flexible injection rate. Nevertheless, the fluctuation of cyclic fuel injection mass (CFIM) in the HPCRIS using a multiple-injection strategy (MIS) reduces the economy of the diesel engine and the stability of vibration and noise control. To realize the precise control of CFIM, the online perception of the injection process is the premise. This paper presents an innovative method for online measurement of injection rate under MIS conditions. According to the evolution characteristics of water hammer pressure oscillation in the fuel system, the rule is that the oscillation form of the water hammer is dependent on the structure of the HPCRIS rather than the injection conditions, and the general applicability of this rule is proved by the hydraulic–electric analog method. Based on this, the method for real-time simulation of the pilot water hammer oscillation wave in the same field is proposed to realize the extraction of the expansion pressure signal components of the main injection. Then, the direct mathematical relationship between the pressure signal and fuel injection rate is established, and the online measurement of fuel injection characteristics under MIS is realized. To improve the robustness of the algorithm a method for real-time calibration of fuel sound velocity is proposed. Finally, when compared with the offline experiment, this method for online measurement of injection rate has relatively high accuracy, the CFIM error is less than 2%, and the goodness of fit of the injection rate curve exceeded 0.91. This measurement method can provide direct feedback to the electronic control unit on the fuel injection system without changing the HPCRIS structure.
Review of high-speed imaging with lab-based x-ray computed tomography
Authors: Zwanenburg E A , Williams M A , Warnett J M 
Published: November 2021

AbstractX-ray computed tomography (CT) is frequently used for non-destructive testing with many applications in a wide range of scientific research areas. The difference in imaging speeds between synchrotron and lab-based scanning has reduced as the capabilities of commercially available CT systems have improved, but there is still a need for faster lab-based CT both in industry and academia. In industry high-speed CT is desirable for inline high-throughput CT at a higher resolution than currently possible which would save both time and money. In academia it would allow for the imaging of faster phenomena, particularly dynamicin-situtesting, in a lab-based setting that is more accessible than synchrotron facilities. This review will specifically highlight what steps can be taken by general users to optimise scan speed with current equipment and the challenges to still overcome. A critical evaluation of acquisition parameters across recent high-speed studies by commercial machine users is presented, indicating some areas that could benefit from the methodology described. The greatest impacts can be achieved by maximising spot size without notably increasing unsharpness, and using a lower number of projections than suggested by the Nyquist criterion where the anecdotal evidence presented suggests usable results are still achievable.

Published: November 2021

Abstract
This paper presents a theoretical and experimental study conducted on the rollover warning of wheeled off-road operating vehicles. The time to rollover warning algorithm was studied with real-time vehicle roll angle and roll angle velocity as the input variables, and lateral load transfer ratio was used as the rollover determination index. Subsequently, a vehicle dynamics model was built using CarSim software, and a warning algorithm was established in the MATLAB/Simulink environment. The rollover joint simulation in CarSim and MATLAB/Simulink was conducted under typical working conditions. Finally, combined with inertial measurements, a rollover warning system was independently developed. In addition, the rollover warning system was installed on a light forest firefighting truck to verify the feasibility of the system via a real vehicle experiment, and the law of vehicle rollover motion was also studied. The serpentine experiment and steady-state rotation experiment were conducted. The experimental results showed that at identical front-wheel steering angles, the roll angle and lateral acceleration increased with an increase in the vehicle speed. Furthermore, for identical vehicle speeds, the roll angle and lateral acceleration of the vehicle increased with an increase in the front-wheel steering angle. The dangerous vehicle speed was 50 km h−1 in the serpentine condition and 40 km h−1 in the steady-state rotation condition. The risk trend and alarm signal obtained by the rollover warning system were consistent with the actual situation. Thus, this can assist drivers in judging the rollover risk and effectively improve the active safety of special vehicles. Furthermore, it also provides a reference for further research on active rollover control technology of special vehicles.

Published: November 2021

Abstract
In this study, we synthesised the Ni/single-walled carbon nanotube prepared by the super-growth method (SG-SWCNTs). In this approach, the Ni nanoparticles were immobilised by an impregnation method using the SG-SWCNTs with high specific surface areas (1144 m2 g−1). The scanning electron microscopy images confirmed that the SG-SWCNTs exhibit the fibriform morphology corresponding to the carbon nanotubes. In addition, component analysis of the obtained samples clarified that the Ni nanoparticles were immobilised on the surface of the SG-SWCNTs. Next, we evaluated the activity for the reduction of 4-nitoropenol in the presence of the Ni/SG-SWCNTs. Additionally, the Ni/graphene, which was obtained by the same synthetic method, was utilised in this reaction. The rate of reaction activity of the Ni/SG-SWCNTs finished faster than that of the Ni/GPs. From this result, the pseudo-first-order kinetic rate constant k for the Ni/SG-SWCNTs and the Ni/GPs was calculated respectively at 0.083 and 0.070 min−1, indicating that the Ni/SG-SWCNTs exhibits higher activity.

Abstract
Supramolecular self-assemble systems based on neoglycolipids: Galili-Ad-CMG2-Ad-DOPE, A(type2)-Ad-CMG2-Ad-DOPE are studied here and compared with the well-studied Biotin-CMG2-Ad-DOPE, as well as with their combinations with NH2-CMG2-Ad-DOPE. They are function-spacer-lipid constructs with unique structure that allows them to form micelle-like supramers and be stable, what makes them a potential drug nanocarriers. The structural properties of the obtained supramolecular systems are studied depending on their functional part, and the loading efficiency of doxorubicin into the supramers is determined to reveal the influence of the functional part. The resulting supramers were separated from the unbound molecules by dialysis, the nanoparticles morphology were studied by atomic force microscopy, and the loading efficiency was calculated based on spectrophotometry data. The encapsulation of doxorubicin was confirmed based on changes in the size and shape of the supramers, as well as a decrease in the ratio of unbound molecules. According to the loading efficiency calculations, it was estimated that supramers formed by A(type2)-Ad-CMG2-Ad-DOPE are the most efficient nanocarriers with loading efficiency of 82 %. Supramers formed by NH2-CMG2-Ad-DOPE (no functional part) showed 1.5 times less efficiency. Finally, the least efficient carriers are supramers formed by Biotin-CMG2-Ad-DOPE (14%).

Authors: Granizo E A , Nabiev I , Krivenkov V 
Published: November 2021

Abstract
Plasmon-induced enhancement of the photoluminescence (PL) intensity of quantum emitters by plasmon nanoparticles (PNPs) is a promising approach for the design and fabrication of PL hybrid materials with improved properties for biosensing and optoelectronics applications. This enhancement can be achieved through careful selection of such parameters as the PNP’s shape, material, size, the type of the medium around them, as well as the excitation and emission wavelengths of the emitter. Here, we simulated the nano-hybrid materials based on arrays of silver nanospheres, nanoprisms, and their combinations, located on polymer films with embedded dipole emitters. For these systems, the Purcell effect, as well as the excitation enhancement, transmittance, and absorption were evaluated. The results show the way to improve the PL properties of thin hybrid films by careful design of their composition using developed models.

Published: November 2021

Abstract
We report on the effect of phosphorus doping of silicon nanowires (SiNWs) on the photoinduced heating processes. SiNWs samples were prepared by metal-assisted chemical etching of low boron-doped crystalline silicon (c-Si) wafers followed with thermo-diffusional doping with phosphorous (P) up to 1020 cm-3. We establish that the P-doping (n-type) results in effective heat conduction along SiNWs toward the c-Si substrate during laser heating. Partial phase transition in P-doped SiNWs under intense photoheating was detected by means of Raman spectroscopy and photoluminescence. The observed doping effects were explained by a contribution of charge carriers (electrons) to the heat distribution along SiNWs and partial screening of the crystal lattice potential. The obtained results can be useful for the development of new photonic and optoelectronic devices based on SiNWs.

AbstractWe elaborated a technique of pulsed laser ablation in gas mixtures (He-N2), maintained under residual pressures of 0.5–5 Torr to deposit silicon (Si)-based nanostructured films on a substrate. We show that the deposited films can exhibit strong photoluminescence (PL) emission with the position of peaks depending on the pressure of ambient gas and the ratio of gases in the mixture. Nanostructured films prepared in pure He gas exhibited a strong band in the infrared range (around 760 nm) and a weak band in the green range (550 nm), which were attributed to quantum-confined excitonic states in small Si nanocrystals and radiative transitions via the localized electronic states in silicon suboxide coating, respectively. In contrast, nanostructured films prepared in He-N2mixtures exhibited more intense “green-yellow” PL band centered at 580 nm, which was attributed to a radiative recombination in amorphous oxynitride (a-SiNxOy) coating of Si nanocrystals. We also present a detailed analysis of morphology of nanostructures Si-based films prepared by laser ablation. Finally, we show that the nanocrystals can be removed from the substrate and milled by ultrasound to form aqueous solutions of colloidal Si nanopartiles. The fabricated Si-based nanocrystals present a promising object for theranostics, combining imaging functionality based on PL emission and a series of therapy functionalities (photo and radiofrequency hyperthermia, photodynamic therapy).

Published: November 2021

Abstract
Mesoporous silicon (mPSi) nanoparticles (NPs) are stabilized by polyethylene glycol (PEG) chains during mechanical grinding in a ball mill that is used to form mPSi-PEG-NPs. The structure, composition, and properties of the obtained samples are studied by means of the dynamic light scattering, scanning electron microscopy and Fourier-transform infrared spectroscopy. The proposed PEGalization procedure is an effective way of regulating the dissolution of mPSi-NPs in water and it is promising for potential application of mPSi-NPs in drug delivery.

Published: November 2021

Abstract
Fast, sensitive, high-throughput detection of coronavirus antigens at physiologically relevant levels is essential for population screening that could prevent epidemics such as the current COVID-19 global pandemic. Optical methods based on surface-enhanced Raman scattering (SERS) spectroscopy are promising for this purpose because they ensure quick detection of even single biological molecules in a sample. For achieving such a high sensitivity, it is crucial to design SERS-active systems concentrating incident radiation into small sample volumes. Here, metal-dielectric cavities have been obtained through interaction of protein sulfhydryl groups with a SERS-active silver surface. The concentration of light in these cavities allows the differential detection of spike glycoprotein and nucleocapsid protein of SARS-COV-2, which are its key antigens, at physiologically relevant concentrations. The cavity Q-factor can be increased by additionally covering the dielectric protein film with a silver shell to form an ultrathin cavity, which provides an at least tenfold enhancement of the detection signal. The results could be used to design high-throughput systems for specific and sensitive detection of viral antigens and quick diagnosis of viral infections.

AbstractHyperthermia is one of the mild cancer treatment approaches, which can be realized via a non-invasive way. It has been established that nanoparticles are effective for local hyperthermia enhancement when stimulated by an external stimulus. We show that silicon-based nanoparticles can be used as sensitizers for radiofrequency-induced hyperthermia and propose a thermographic method to control the temperature during the treatment.

Authors: Belov V S , Bobkov E A , Oleschenko V A , Kabashin A V , Timoshenko V Yu 
Published: November 2021

Abstract
Temperature oscillations (pulsations) were detected in aqueous suspensions of silicon (Si) nanoparticles NPs under laser irradiation with highly absorbed light. The temperature pulsation frequency was found to depend on the NPs concentration in suspension and laser irradiation power. The observed phenomenon is assumed to be caused by the local overheating of Si NPs close to the boiling point of water, while the average heating of the surrounding liquid was insignificant. The observed phenomenon is discussed in view of potential applications in local photo-induced hyperthermia of cancer.

Published: November 2021

Abstract
The mortality rate from various oncological diseases remains consistently extremely high, even in spite of recent breakthrough discoveries in the field of cancer therapy [1-3]. One of the most promising cancer treatments is photodynamic therapy (PDT) combined with fluorescence diagnostics (FD) [4, 5]. This study aims to evaluate the efficiency of the PDT procedure using an experimental LED device for photodynamic therapy and fluorescence diagnostics of neoplasms by the level of photobleaching of the photosensitizer protoporphyrin IX (PPIX) in optical phantoms of the skin. The results of spectral measurements showed that the LEDs is able to effectively induce oxidative stress in cancer cells, and due to the presence of a video system, it becomes possible to register the level of tissue fluorescence.

Published: November 2021

Abstract
The aim of this work was to study the effect of the reduced acquisition time of PET 11C-MET examination on the quality of primary brain tumors differential diagnosis. 57 patients with histologically verified diagnoses were recruited (glioblastoma n=20, anaplastic astrocytoma n=11, diffuse astrocytoma n=11, oligodendroglioma n=9 and anaplastic oligodendroglioma n=6). The scan time was varied in the range of 2-20 min. Our study demonstrated that in the case of intravenous administration of 11C-MET simultaneously with the start of scanning, the quality of primary gliomas differential diagnosis does not depend on the scan time. Therefor it becomes possible increasing the number of patients and reducing the acquisition time. The T/N60 ratio (T/N ratio measured in the first 60 seconds after 11C-MET intravenous injection) is equally successful parameter for glioma differential diagnosis as the traditional T/N ratio.
