Christ as Yogi: The Jesus of Vivekananda and Modern Hinduism
Authors: Neumann David J.
Published: July 2021

Swami Vivekananda was the most influential pioneer of a Yogi Christ, illustrating well over a century ago how the life and teachings of Jesus might be incorporated within a larger Hindu worldview—and then presented back to Western audiences. Appropriation of Jesus, one of the central symbols of the West, might be viewed as the ultimate act of counter-Orientalism. This article begins by providing a brief biography of Vivekananda and the modern Hinduism that nurtured him and that he propagated. He articulated an inclusivist vision of Advaita Vedanta as the most compelling vision of universal religion. Next, the article turns to Vivekananda's views of Christianity, for which he had little affection, and the Bible, which he knew extraordinarily well. The article then systematically explores Vivekananda's engagement with the New Testament, revealing a clear hermeneutical preference for the Gospels, particularly John. Following the lead of biblical scholars, Vivekananda made a distinction between the Christ of the Gospels and the Jesus of history, offering sometimes contradictory conclusions about the historicity of elements associated with Jesus's life. Finally, the article provides a detailed articulation of Vivekananda's Jesus—a figure at once familiar to Christians but, in significant ways, uniquely accommodated to Hindu metaphysics. Vivekananda demonstrated a robust understanding and discriminating use of the Christian Bible that has not been properly recognized. He deployed this knowledge to launch an important and long-lived pattern: an attractive, fleshed out depiction of Jesus of Nazareth, transformed from the Christian savior into a Yogi model of self-realization. Through his efforts, Jesus became an indisputably Indian religious figure, no longer just a Christian one. The Yogi Christ remains a prominent global religious figure familiar to Hindus, Christians, and those of other faiths alike.
New York City and the Production of Sacred Space

Jon Butler's God in Gotham: The Miracle of Religion in Modern Manhattan affirms what historians of religion have long known and some urban historians have begun to discover—that few things in American history have survived so well as religion. Political moments and social movements have come and gone. Fashions have fallen out of favor; fads have faded. But that thing that we call “religion”—however defined, theologically, experientially, or institutionally—has survived, even thrived, particularly in American cities and perhaps most particularly in America's largest city, New York.

Published: July 2021

Nearly half of patients with non-cardiac chest pain (NCCP) experience significant complaints after a negative cardiac evaluation, at considerable costs for society. Due to the lack of treatment capacity and low interest for psychological treatment among patients with somatic complaints, only a minority receive effective treatment. The aim of this study was to assess the feasibility and usefulness of internet-assisted cognitive behavioural therapy (I-CBT), including encouragement of physical activity for this condition. Ten patients with NCCP received a six-session I-CBT intervention with minimal support from a therapist. Questionnaires assessing cardiac anxiety, fear of bodily sensations, depression, interpretation of symptoms, frequency of chest pain and impact of chest pain symptoms were collected at baseline, post-treatment and at 3-month follow-up. Semi-structured interviews employing a phenomenological hermeneutic approach assessed the participants’ experience of the intervention. Quantitative results showed clear improvements in several measures both at end of treatment and at 3-month follow-up. The retention rate was 100% and client satisfaction was high. The intervention was feasible to implement in a cardiac setting. This setting made it easier for patients to accept a psychological approach. Qualitative interviews revealed that the participants felt respected and taken care of, and they obtained a better understanding of their chest pain and how to cope with it. This pilot study yielded promising results regarding feasibility, clinical effect and patient satisfaction from a brief I-CBT intervention for NCCP in a cardiac setting. These results indicate that a randomized controlled trial with a larger sample size is warranted.

Low limit of detection of the AlGaN/GaN-based sensor by the Kelvin connection detection technique
Authors: Zhang Hanyuan , Gan Ying , Yang Shu , Sheng Kuang , Wang Ping
Published: July 2021

The AlGaN/GaN-based sensor is a promising POCT (point-of-care-testing) device featuring miniaturization, low cost, and high sensitivity. BNP is an effective protein biomarker for the early diagnosis of HF (heart failure). In this work, a novel AlGaN/GaN device with the Kelvin connection structure and the corresponding detection technique was proposed. This technique can effectively suppress the background noise and improve the SNR (signal-to-noise ratio). A BNP detection experiment was carried out to verify the effectiveness of this technique. It is shown that compared with that of the traditional detection method, the LOD (limit of detection) was improved from 0.47 ng/mL to 1.29 pg/mL. The BNP detection experiment was also carried out with a traditional electrochemical Au-electrode sensor with the same surface functionalization steps. The AlGaN/GaN sensor showed a better LOD than the Au-electrode sensor. Moreover, the influence of AlGaN/GaN sensor package on background noise was investigated with the mechanism of the noise source revealed. Finally, based on the optimized package, the optimal SNR quiescent operating point of the AlGaN/GaN sensor was determined. By biasing the sensor at the optimal quiescent operating point and immobilizing the magnetic beads with anti-BNP on the gate of the AlGaN/GaN sensor, the LOD for BNP detection was further improved to 0.097 pg/mL.

Published: July 2021

Three E. coli O157:H7 outbreaks have been attributed to contaminated pork in Alberta, Canada, recently. This study investigates the phylogenetic relatedness of E. coli O157:H7 from pigs, cattle, and pork-production environments for source attribution. Limited strain diversity was observed using five conventional subtyping methods, with most or all strains being in one subgroup. Whole-genome single nucleotide polymorphism analysis confirmed the recent ancestry of the isolates from all three sources. Most environmental isolates clustered closer with pig isolates than cattle isolates. Also, a direct link was observed between 2018-outbreak environmental isolates and isolates collected from a pig farm in 2018. The majority of pig isolates harbor only one Shiga toxin gene, stx2a, while 70% (35/50) of the cattle isolates have both stx1a and stx2a. The results show some E. coli O157:H7 strains could establish persistence on pig farms and as such, pigs can be a significant source of the organism.

Published: July 2021

The inability to over-express Aquaporin 6 (AQP6) in the plasma membrane of heterologous cells has hampered efforts to further characterize the function of this aquaglyceroporin membrane protein at atomic detail using crystallographic approaches. Using an Aquaporin 3-tGFP Reporter (AGR) system we have identified a region within loop C of AQP6 that is responsible for severely hampering plasma membrane expression. Serine substitution corroborated that amino acids present within AQP6194–213 of AQP6 loop C contribute to intracellular endoplasmic reticulum (ER) retention. This intracellular retention signal may preclude proper plasma membrane trafficking and severely curtail expression of AQP6 in heterologous expression systems.

Published: July 2021

Polyamine detection and depletion have been extensively investigated for cancer prevention and treatment. However, the therapeutic efficacy is far from satisfactory, mainly due to a polyamine compensation mechanism from the systemic circulation in the tumor environment. Herein, we explore a new solution for improving polyamine detection as well as a possible consumption therapy based on a new photosensitizer that can efficiently consume polyamines via an irreversible chemical reaction. The new photosensitizer is pyrrolopyrroleaza-BODIPY pyridinium salt (PPAB-PyS) nanoparticles that can react with the over-expressed polyamine in cancer cells and produce two photosensitizers with enhanced phototoxicity on cancer destruction. Meanwhile, PPAB-PyS nanoparticles provide a simultaneous ratiometric fluorescence imaging of intracellular polyamine. This combination polyamine consumption with a chemical reaction provides a new modality to enable polyamine detection along with photodynamic therapy as well as a putative depletion of polyamines for cancer treatment and prevention.

The coronavirus 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), spread around the world with unprecedented health and socio-economic effects for the global population. While different vaccines are now being made available, very few antiviral drugs have been approved. The main viral protease (nsp5) of SARS-CoV-2 provides an excellent target for antivirals, due to its essential and conserved function in the viral replication cycle. We have expressed, purified and developed assays for nsp5 protease activity. We screened the nsp5 protease against a custom chemical library of over 5000 characterised pharmaceuticals. We identified calpain inhibitor I and three different peptidyl fluoromethylketones (FMK) as inhibitors of nsp5 activity in vitro, with IC50 values in the low micromolar range. By altering the sequence of our peptidomimetic FMK inhibitors to better mimic the substrate sequence of nsp5, we generated an inhibitor with a subnanomolar IC50. Calpain inhibitor I inhibited viral infection in monkey-derived Vero E6 cells, with an EC50 in the low micromolar range. The most potent and commercially available peptidyl-FMK compound inhibited viral growth in Vero E6 cells to some extent, while our custom peptidyl FMK inhibitor offered a marked antiviral improvement.

Published: July 2021

The paper considers methods for calculating the mode of a stationary random process when solving the problem of processing measurement results under conditions of a priori uncertainty. The results of the conducted studies allowed us to conclude that the most effective method for calculating the mode for a given sample is the proposed method, which allows to increase the accuracy of its calculation by at least 8 times, compared to methods based on the construction of histograms. It should be noted that the proposed method allows to provide an estimate with an error of at least 5% for samples with a number of measurements of about 5 value.

Published: July 2021

This paper, describes a developed simulation model that gives the ability to simulate various situations of possible fire occurrence and study the behavior of people during their evacuation, taking into account various factors in different types of buildings, which allows the prediction of the consequences of a fire and subsequently develop rules for human behavior in extreme situations. Studies have shown that the optimization of movement during the simulation of a fire made it possible to reduce the likelihood of fire by approximately 20%, and the presence of an emergency exit reduces it by another 30%, which makes it possible to optimize the results of modeling the consequences of a fire in rooms of various types.

Published: July 2021

In this work, it is shown that intensive treatment of dispersed systems with ultrasound is an effective method for enhancing the interaction of particles and polymer with the subsequent formation of adsorption layers of high thickness and strength. This makes possible to obtain highly stable dispersed systems with a modified surface of the solid phase. The studies proved the important role of intensive ultrasonic action for controlling the properties of the nanoparticles surface in heterophase systems. It is shown that an increase in the activity of the surface of nanoparticles as a result of ultrasonic treatment is of great importance for the study of their antibacterial activity: after ultrasonic activation, nanoparticles are more active in interaction with cell membranes.
Mathematical model for calculating the force field of loads in the magnetic liquefied layer of electromechanical dispersants
Authors: Bezzubceva Marina , Volkov Vladimir
Published: July 2021

The article presents an analysis of the dominant dispersants in the production of the agro-industrial complex. A qualitative transition to the level of a priori reduction of energy costs for the most energy-intensive in the process flow and process instrumentation diagrams of the agro-industrial complex process of grinding of materials was found to be possible through the development and creation of devices, which, due to their design, increase the power of the force impact on the product to be processed. Numerous theoretical and practical studies within the framework of the scientific school “Efficient use of energy, intensification of technological processes” have confirmed that dispersants using electromagnetic fields, which form dispersing loads controlled by magnitude in energy-stressed contact interactions of ferro-bodies in their magnetic liquefied bed, can provide a product of a given quality with a minimum energy intensity indicator. The mathematical model of calculating the force field of loads in the magnetic liquefied bed of electromechanical dispersants presented in the article allows, as the practice has shown, developing the design schemes of electromagnetic mills, providing both the output of finished products with a high degree of selectivity, and with minimal energy consumption for the hardware arrangement of the technological process.

Influence of the Mg content on the austenite grain growth in heat-affected zone of offshore engineering steels considering TiN particle pinning and Mo solute drag effects
Authors: Pan Xiaoqian , Yang Jian , Zhang Yinhui , Park Joohyun , Ono Hideki
Published: July 2021

The submicrometre and nanometre particle characteristics, soluble element contents, and austenite grain growth behaviors in heat-affected zone of offshore engineering steels with 0.0002 (2Mg) and 0.0042 (42Mg) wt.% Mg during the simulated welding process were studied. With increasing the Mg content in steel from 0.0002 to 0.0042 wt.%, the submicron particles are decreased in number and size with their compositions evolved from TiN to TiN + MgO capped with Mo carbides, and the number density of small-sized nanoparticles increases and large-sized nanoparticles decreases. When the temperature is below 1250 °C, the grain growth rate of two steels is not much different due to the larger Mo solute drag effect in 2Mg and larger pinning force in 42Mg. When the temperature is 1250–1300 °C, the small-sized nanoparticles in 42Mg is more than that in 2Mg, resulting in the larger pinning force and smaller grain growth rate in 42Mg. When heated to 1300–1350 °C and soaked at 1350 °C for 300 s, since large quantities of particles smaller than the critical size (dcr) are dissolved, the grain growth rate in 2Mg is smaller than that in 42Mg due to the greater amount of the effective pinning particles and larger pinning force in 2Mg.

Trabeculectomy with OloGen versus Mitomycin C for the Treatment of Silicone Oil-Induced Glaucoma
Authors: Shalaby Hisham Samy , Hashem Noureldin Hussein
Published: July 2021

Aim To compare the intraocular pressure-lowering effect and success rate of trabeculectomy with OloGen to that of trabeculectomy with mitomycin C (MMC) in cases of silicone oil-induced glaucoma.

Materials and Methods Forty eyes of forty patients with elevated intraocular pressure (IOP) after vitrectomy and silicone oil injection (followed by silicone oil removal) were assigned to two groups. Group A included 20 cases who underwent trabeculectomy with OloGen, while group B cases contained 20 cases undergoing trabeculectomy with MMC. The follow-up period was 24 months. Patients enrolled had IOP > 21 mmHg despite being on antiglaucoma medications.

Results The mean postoperative IOP reduction was lower in group A than in group B at all follow-up visits, but this difference was not statistically significant (p > 0.05). Moreover, group A and B patients were found to be similar as regards the need for postoperative antiglaucoma medications on all follow-up visits. The Kaplan-Meier survival analysis curves for the two groups revealed slightly higher success rates in group B than in group A. However, these differences were not statistically significant for both qualified success (IOP ≤ 21 mmHg with or without antiglaucoma medications) and complete success (IOP ≤ 21 mmHg without antiglaucoma medications). There was no significant difference in the postoperative complication rate between the two groups.

Conclusion OloGen implant lowers IOP to a similar extent as MMC when combined with trabeculectomy for the treatment of silicone oil-induced glaucoma, and with comparable success rates. The rate of postoperative complications is similar for OloGen implantation and MMC.

Published: July 2021

Background Treatment of Zenker’s diverticulum has evolved from open surgery to endoscopic techniques, including flexible and rigid endoscopic septotomy, and more recently, peroral endoscopic myotomy (Z-POEM). This study compared the effectiveness of flexible and rigid endoscopic septotomy with that of Z-POEM.

Methods Consecutive patients who underwent endoscopic septotomy (flexible/rigid) or Z-POEM for Zenker’s diverticulum between 1/2016 and 9/2019 were included. Primary outcomes were clinical success (decrease in Dakkak and Bennett dysphagia score to ≤ 1), clinical failure, and clinical recurrence. Secondary outcomes included technical success and rate/severity of adverse events.

Results 245 patients (110 females, mean age 72.63 years, standard deviation [SD] 12.37 years) from 12 centers were included. Z-POEM was the most common management modality (n = 119), followed by flexible (n = 86) and rigid (n = 40) endoscopic septotomy. Clinical success was 92.7 % for Z-POEM, 89.2 % for rigid septotomy, and 86.7 % for flexible septotomy (P = 0.26). Symptoms recurred in 24 patients (15 Z-POEM during a mean follow-up of 282.04 [SD 300.48] days, 6 flexible, 3 rigid [P = 0.47]). Adverse events occurred in 30.0 % rigid septotomy patients, 16.8 % Z-POEM patients, and 2.3 % flexible septotomy patients (P < 0.05).

Conclusions There was no difference in outcomes between the three treatment approaches for symptomatic Zenker’s diverticulum. Rigid endoscopic septotomy was associated with the highest rate of complications, while flexible endoscopic septotomy appeared to be the safest. Recurrence following Z-POEM was similar to flexible and rigid endoscopic septotomy. Prospective studies with long-term follow-up are required.

Radiation reaction in higher-order electrodynamics
Authors: Hoang Vu , Radosz Maria , Harb Angel , DeLeon Aaron , Baza Alan
Published: July 2021

This paper considers the relativistic motion of charged particles coupled with electromagnetic fields in the higher-order theory proposed by Bopp, Landé–Thomas, and Podolsky. We rigorously derive a world line integral expression for the self-force of the charged particle from a distributional equation for the conservation of four-momentum only. This naturally leads to an equation of motion for charged particles that incorporates a history-dependent self-interaction. We show additionally that the same equation of motion follows from a variational principle for retarded fields. Our work thus gives a rigorous vindication of an expression for the self-force first proposed by Landé and Thomas, studied by Zayats for straight line motion, and, more generally, obtained by Gratus, Perlick, and Tucker on the basis of an averaging axiom.
Slightly compressible Forchheimer flows in rotating porous media
Authors: Celik Emine , Hoang Luan , Kieu Thinh
Published: July 2021

We formulate the generalized Forchheimer equations for the three-dimensional fluid flows in rotating porous media. By implicitly solving the momentum in terms of the pressure’s gradient, we derive a degenerate parabolic equation for the density in the case of slightly compressible fluids and study its corresponding initial boundary value problem. We investigate the nonlinear structure of the parabolic equation. The maximum principle is proved and used to obtain the maximum estimates for the solution. Various estimates are established for the solution’s gradient, in the Lebesgue norms of any order, in terms of the initial and boundary data. All estimates contain explicit dependence on key physical parameters, including the angular speed.
Bi(III) halometallate ionic liquids: Interactions and speciation
Authors: Rowe Rebecca , Lovelock Kevin R. J. , Hunt Patricia A.
Published: July 2021

Bismuth containing compounds are of particular interest for optical or photo-luminescent applications in sensing, bio-imaging, telecommunications, and opto-electronics and as components in non-toxic extremely dense liquids. Bismuth(III) halometallates form highly colored novel ionic liquid based solvents for which experimental characterization and fundamental understanding are limited. In this work, Bismuth(III) halometallates incorporating chloride, bromide, and iodide have been studied via density functional theory employing B3LYP-D3BJ/aug-cc-pVDZ. Lone anions, and anions in clusters with sufficient 1-ethyl-3-methyl-imidazolium [C2C1Im]+ counter-cations to balance the charge, have been investigated in the gas- phase, and with polarizable continuum solvation. Evaluation of speciation profiles indicates that dimeric or trimeric anions are prevalent. In contrast to analogous Al systems, anions of higher charge (−2, −3) are present. Speciation profiles are similar, but not identical with respect to the halide. The Bi based anions [BimXn]x− in the gas phase and generalized solvation environment produce multiple low energy conformers; moreover, key structural interaction patterns emerge from an analysis of ion-pair and neutral-cluster structures (BimXn)x−(C2C1Im)x+ for x = 1, 2, and 3. Cation–anion interactions are weak; with Coulombic and dispersion forces predominating, anion–π structures are favored, while significant hydrogen bonding does not occur. Anion to cation charge transfer is minimal, but mutual polarization is significant, leading to local positive regions in the anion electrostatic potential surface. The key features of experimental x-ray photoelectron, UV–Vis spectra, and Raman spectra are reproduced, validating the computational results and facilitating rationalization of key features.
Resonant-type inertial impact piezoelectric motor based on a cam locking mechanism
Authors: He Liangguo , Gao Guangjie , Kan Yan , Hao Sai , Li Xinyu , Ge Xinfang , Chen Jian , Chang Weijie
Published: July 2021

A new resonant-type inertial impact piezoelectric motor based on a cam locking mechanism was designed, assembled, and tested. The motor is composed of a stator, a rotor, and other auxiliary components. The cam clamping foot of the stator in contact with the inner surface of the rotor forms a cam locking mechanism, which can make the resonant vibration of the stator effective in a half cycle. By receiving sinusoidal signals, the stator generates bending deformation due to the regular deformation of the piezoelectric plate, which drives the cam clamping foot to move and subsequently causes the rotor to rotate. COMSOL5.4 finite element analysis software was used to design the structure of the piezoelectric motor, and an experimental device was built to evaluate and verify the performance of the motor. The maximum no-load speed of the prototype reached 21.61 rpm and the maximum load torque of the motor was 84 N mm under a driving voltage of 360 Vp–p and a driving frequency of 388 Hz. The motor achieved a net efficiency of 5.6% under a preload torque of 2 N mm with the same condition.

Numerical investigations of three-dimensional flows around a cylinder attaching with symmetric strips

Published: July 2021

Minor changes to the surface of a cylinder can significantly influence the associated flow characteristics. This paper describes a three-dimensional numerical investigation of a cylinder attached with symmetric strips in a uniform flow at Re=3900. The location (20°≤α≤130°), thickness (0.01D≤t≤0.08D), and coverage (5°≤β≤100°) of the strips are selected for study. Two flow modes, patterns A and D, can be characterized in the flow around this passive turbulence control cylinder by their vortex enhancement and suppression effects. The Strouhal number of pattern A is very close to the response of a smooth cylinder. For cylinders with the upper strip located at α≤90° from the front stagnation point, the lift force correlation in the spanwise direction is enhanced by the forced flow separation. When the front edge of the upper strip is fixed at α=60°, the thickness of the strips plays a vital role: the drag and lift force increase linearly as the thickness increases, whereas the Strouhal number and the vortex shedding frequency decrease.

TIPS-pentacene is a small-molecule organic semiconductor that is widely used in optoelectronic devices. It has been studied intensely owing to its ability to undergo singlet fission. In this study, we aim to develop further understanding of the coupling between the electronic and nuclear degrees of freedom of TIPS-pentacene (TIPS-Pn). We measured and analyzed the 2D electronic spectra of TIPS-Pn in solutions. Using center line slope (CLS) analysis, we characterized the frequency-fluctuation correlation function of the 0–0 vibronic transition. Strong oscillations in the CLS values were observed for up to 5 ps with a frequency of 264 cm−1, which are attributable to a large vibronic coupling with the TIPS-Pn ring-breathing vibrational mode. In addition, detailed analysis of the CLS values allowed us to retrieve two spectral diffusion lifetimes, which are attributed to the inertial and diffusive dynamics of solvent molecules. Amplitude beating analysis also uncovered couplings with another vibrational mode at 1173 cm−1. The experimental results can be described using the displaced harmonic oscillator model. By comparing the CLS values of the simulated data with the experimental CLS values, we estimated a Huang–Rhys factor of 0.1 for the ring-breathing vibrational mode. The results demonstrated how CLS analysis can be a useful method for characterizing the strength of vibronic coupling.

Ultrawide-band-gap (UWBG) semiconductors are promising for fast, compact, and energy-efficient power-electronics devices. Their wider band gaps result in higher breakdown electric fields that enable high-power switching with a lower energy loss. Yet, the leading UWBG semiconductors suffer from intrinsic materials' limitations with regard to their doping asymmetry that impedes their adoption in CMOS technology. Improvements in the ambipolar doping of UWBG materials will enable a wider range of applications in power electronics as well as deep-UV optoelectronics. These advances can be accomplished through theoretical insights on the limitations of current UWBG materials coupled with the computational prediction and experimental demonstration of alternative UWBG semiconductor materials with improved doping and transport properties. As an example, we discuss the case of rutile GeO2 (r-GeO2), a water-insoluble GeO2 polytype, which is theoretically predicted to combine an ultra-wide gap with ambipolar dopability, high carrier mobilities, and a higher thermal conductivity than β-Ga2O3. The subsequent realization of single-crystalline r-GeO2 thin films by molecular beam epitaxy provides the opportunity to realize r-GeO2 for electronic applications. Future efforts toward the predictive discovery and design of new UWBG semiconductors include advances in first-principles theory and high-performance computing software, as well as the demonstration of controlled doping in high-quality thin films with lower dislocation densities and optimized film properties.

Nanoemulsions consist of small particle size, uniform dispersion, and long-term stability, making them suitable for use in enhanced oil recovery for low-permeability reservoirs. In this paper, an ultrastable oil-in-water nanoemulsion was prepared using the emulsification inverse phase method at a constant temperature. Rheology, multiple-light scattering, laser particle size analyzer, and optical microscope were used to determine the effects of the emulsifier and water content, salinity, and reservoir temperature on the stability of the prepared nanoemulsion. The oil washing performance of nanoemulsion was tested by the weight-loss method. Results show that the nanoemulsions tend to be stable with an increase in the emulsifier content (≥8 wt. %). As the water content increases, the viscosity of nanoemulsions gradually decreases as well as its elasticity. The salinity and temperature are found to have minor effects on the stability of nanoemulsions. At the same time, the oil washing efficiency of nanoemulsion can reach as high as 83%. Hence, this study will provide theoretical supports and guidelines for the preparation of highly efficient nanoemulsion flooding systems for low-permeability reservoirs.

Predator diet can provide important data to inform management actions as well as an enhanced understanding of the fauna of a region. The diet of dingo (Canis lupus dingo), feral cat (Felis catus) and eastern barn owl (Tyto delicatula) were compared using scat, stomach and pellets from a significant conservation reserve in southwest Queensland. Dingo diet was dominated by macropods, while the diet of feral cat and barn owl was dominated by small mammals. We found no remains of threatened species but recommend continued monitoring of predator diet as a tool to assist management.

Authors: Kalhor Alireza , Karimi Taheri Ali , Mirzadeh Hamed , Uthaisangsuk Vitoon
Published: July 2021

In this review, effects of initial microstructure before intercritical annealing and processing routes of dual phase (DP) high strength steels are discussed. Prior-applied deformation processes as cold rolling and severe plastic deformation (SPD) including their impacts on mechanical properties of DP steels are described. Influences of heating rate, recrystallization of ferrite, nucleation and grain growth of austenite on the microstructure evolution are also presented. The intercritical annealing and thermomechanical processes of DP steels are comparatively outlined. Furthermore, post-intercritical annealing treatments, i.e., tempering, bake hardening, strain and quench aging are argued. Effects of key alloying elements on the microstructure and mechanical properties of DP steels are briefly summarized. A further development of DP steels can properly benefit from this extensive review.
Subjective visual vertical and horizontal
Authors: Dessai Teja Deepak , Prasannan Anaswara
Published: July 2021

Objective

The Subjective Visual Vertical (SVV) and Subjective Visual Horizontal (SVH) are convincing tools to assess otolithic organ and/or central gravio-ceptive pathways. This study was undertaken to establish normative of SVV and SVH in different age groups from Indian population.

Methods

A total of 180 subjects divided into 6 groups 30 each with respect to age (10–20, 21–30, 31–40, 41–50, 51–60 years) were recruited in the study. Testing was administered using the bucket technique. The subject was instructed to rotate the bucket to match his/her perceptual visual vertical and horizontal. The movement of the bucket in the clockwise and counter-clockwise directions made the string tied to the weight rotate freely. This made it possible for the investigator to read the findings on protractor.

Results

SVH and SVV range between −1 to +3 which is in congruence with the findings of literature. However, there is no significant difference observed across age groups for both SVV and SVH.

Conclusion

The study provides normative for SVV and SVH which can be considered as reference values to assess a subject with acute peripheral vestibular pathology. The test findings can be grouped with counselling and rehabilitation to improve the subject’s quality of life.

Polymeric nitrogen is a promising candidate for a high-energy-density material. Synthesis of energetic compounds with high chemical stability under ambient conditions is still a challenging problem. Here we report a theoretical study on yttrium nitrides by first principles calculations combined with an effective crystal structure search method. It is found that many yttrium nitrides with high nitrogen content can be formed under relatively moderate pressures. The results indicate that the nitrogen-rich YN5 and YN8 compounds are recoverable as metastable high-energy materials under ambient conditions, and can release enormous energies (2.51 kJ·g−1 and 3.18 kJ·g−1) while decomposing to molecular nitrogen and YN. Our findings enrich the family of transition metal nitrides, and open avenues for design and synthesis of novel high-energy-density materials.

Published: July 2021

Interfacial structure evolution and degradation are critical to the electrochemical performance of LiCoO2 (LCO), the most widely studied and used cathode material in lithium ion batteries. To understand such processes requires precise and quantitative measurements. Herein, we use well-defined epitaxial LCO thin films to reveal the interfacial degradation mechanisms. Through our systematical investigations, we find that surface corrosion is significant after forming the surface phase transition layer, and the cathode electrolyte interphase (CEI) has a double layer structure, an inorganic inner layer containing CoO, LiF, LiOH/Li2O and Li

, and an outmost layer containing Li2CO3 and organic carbonaceous components. Furthermore, surface cracks are found to be pronounced due to mechanical failures and chemical etching. This work demonstrates a model material to realize the precise measurements of LCO interfacial degradations, which deepens our understanding on the interfacial degradation mechanisms.
Wavelength sensitivity of the speckle patterns produced by an integrating sphere

Published: July 2021

Speckle metrology is a powerful tool in the measurement of wavelength and spectra. Recently, speckle produced by multiple reflections inside an integrating sphere has been proposed and showed high performance. However, to our knowledge, a complete characterisation of speckle sensitivity to wavelength in that geometry has not been performed to date. In this work, we derive a general model predicting the variation in a speckle pattern as a result of a generic transformation. Applying this to a shift in the incident wavelength, we show that the speckle sensitivity is mainly governed by the radius and surface reflectivity of the sphere. We show that integrating spheres offer sensitivity four orders of magnitude above that of multimode fibres of a similar size, and discuss analogies with the transmission profile of a Fabry–Pérot interferometer.
