Meditations on an Expanded, Narrative Inquiry Methodology Combining Clinical Dynamic Understanding and Biography

As a meditation on a method of narrative inquiry, this paper describes an ongoing project which integrates a narrative, portrait-based approach to clinical storytelling with a clinically-focused dialogical process. Expanding upon previous narrative work completed by Michael O’Loughlin and colleagues, this research is a single-case, longitudinal, qualitative exploratory study of an individual who has struggled with psychosis, been exposed to the psychiatric care system, and transmuted their life history through artistic sublimation. In addition to producing a biographical portrait, the purpose of this study’s expanded methodology is to invite a reflective, dialogical process that allows for autobiographical engagement, verification and co-construction of the emerging life story, and deepening conversations about the complexities of human struggle. It is my hope that, through a version of dialogical exchange and narrative practice in the tradition of Michael White, this research provides a way in which clinicians and researchers can facilitate curative, biographical spaces for those with painful lived experience and inherited trauma. By receiving, tracking, and validating human thought and experience, this work aims to combine the portraiture of rendering a life with an in-depth exploration of the complexities of and intersectionality between subjectivity, severe psychiatric distress, creativity, counter-storying, and narrative healing.
Prevalence of Noise-Induced Tinnitus in Adults Aged 15 to 25 Years: A Cross-Sectional Study

Background Tinnitus is a common complaint in the general population. Subjective tinnitus is defined as a conscious perception of sound with nonexistent external stimuli. Its exact pathophysiology remains unclear. Therefore, this study aimed to determine the prevalence of noise-induced tinnitus among adults aged 15-25 years in Makkah, Saudi Arabia. Study design Convenience sampling was used for participant recruitment using an online survey that was distributed online between February and April 2022. The participants performed audiometric hearing tests provided by the investigators. Hearing tests were performed at frequencies of 250, 500, 1000, 2000, 4000, and 8000 Hz. The test was considered normal if the achieved thresholds were 25 dB HL or less in at least four of the tested frequencies. Those with normal results were asked to fill out a survey inquiring about their demographic information, presence of tinnitus, and tinnitus functional index. Results We included 119 young adults aged 15-25 years. Regarding tinnitus prevalence, 27 (22.7%) adults reported the development of tinnitus after exposure to loud noise, 39 (32.8%) had tinnitus of unknown cause, and 53 (44.5%) had no tinnitus. Regarding the continuity of sound, it was continuous in 14.8% of noise-induced tinnitus, compared to 38.5% of the other group, with a statistical significance of (P=.037). Conclusion The current study revealed high prevalence of tinnitus, which was also suggested by the literature. Several triggers are purportedly related to the development of tinnitus. Constant exposure to loud noise is considered a significant risk factor for tinnitus. Young adults require proper education about the causes of tinnitus and other hearing abnormalities. More importantly, methods to protect and maintain their ear health.
Evaluation of Sensitivity and Specificity of Direct Microscopical Examination of Suspected Mucor Mycosis Samples by Potassium Hydroxide (KOH) during Covid-19 Pandemic Era

Multifractal formalism derived from thermodynamics for general dynamical systems

We show that under quite general conditions, various multifractal spectra may be obtained as Legendre transforms of functions $T$: $ \RR\to \RR$ arising in the thermodynamic formalism. We impose minimal requirements on the maps we consider, and obtain partial results for any continuous map $f$ on a compact metric space. In order to obtain complete results, the primary hypothesis we require is that the functions $T$ be continuously differentiable. This makes rigorous the general paradigm of reducing questions regarding the multifractal formalism to questions regarding the thermodynamic formalism. These results hold for a broad class of measurable potentials, which includes (but is not limited to) continuous functions. Applications include most previously known results, as well as some new ones.

The motion characteristic of cavitation bubble is one of the major factors affecting acoustic cavitation. In this paper, a cavitation model coupled with acoustic pressure is established using lattice Boltzmann pseudopotential model. Aimed at demonstrating the feasibility of applying LB method in acoustic cavitation, the acoustic cavitation simulations are compared with the predictions of Keller equation. The comparison of theoretical prediction and numerical simulation shows that LB method is suitable for acoustic cavitation simulation.

Texture Image Recognition Based on Deep Convolutional Neural Network and Transfer Learning

: The traditional texture image recognition methods have a complex design process, and the existing methods based on deep learning can’t effectively solve the problem of insufficient texture image samples which lead to unsatisfying recognition accuracy. To solve the above problems, a texture image recognition method based on deep convolutional neural network and transfer learning is proposed. Firstly, a new transfer learning model is constructed by using the deep learning model pretrained on the large-scale ImageNet image dataset. Secondly, the reasonable model super-parameters are set, and the weighted sum of the training loss, the validation loss

We present a technique for designing wideband focusing metasurfaces. The proposed metasurface consists of unit cells of nanoparticle-based spatial phase shifters distributed over a planar surface. The topology of each spatial phase shifter is based on the design of plasmonic frequency selective surfaces. A true ab-initio design procedure for the proposed reflectarray is also proposed for the desired bandwidth and center frequency. A reflectarray for focusing the entire red spectrum (75 nm) is designed, with full-wave simulation results demonstrating desired focusing.
Study on Thin Film Thermocouple Measuring Instantaneous Temperature on Surface of Combustion Chamber Wall In Internal Combustion Engine : 2nd Report, Study on Thin Film Thermocouples Embedded in Combustion Chamber Wall

Following a study in which the area surrounding thin film thermocouples was assumed to be heat insulated as reported previously, the distribution of temperatures in thin film thermocouples embedded in combustion chamber walls of internal combustion engines which were in steady-state and unsteady-state temperature fields was studied, where the equations of different element methods, introduced in previous report, were expanded. Effects of the adiabatic layer and thermocouple body materials on the measured combustion chamber wall surface temperatures and heat fluxes were studied. As a result, it was indicated that thin film thermocouples capable of measuring instantaneous temperatures and heat fluxes on the combustion chamber wall with high accuracy, could be produced.
Influence of the critical point on the electrocaloric response of relaxor ferroelectrics

The electrocaloric effect (ECE), i.e., the conversion of electric energy into heat, is of great importance for application in new generation cooling or heating devices that would be friendlier to the environment. Here, utilizing direct measurements of the ECE change of the temperature ΔT via a high resolution calorimeter, we study the ECE as a function of the magnitude of the electric-field step E in the vicinity of the critical point in several bulk relaxor ferroelectric ceramic systems. Relatively large ΔT of ∼2 to 3 K were obtained at modest fields of 90 kV/cm, even in the case of ceramic materials. The effective responsivity ΔT/E as a function of the electric field shows a characteristic peak near the critical point, which demonstrates the importance of proximity to the critical point for the enhancement of the electrocaloric effect. Experimental results are in good agreement with the theoretical calculations based on the spherical random-bond random-field model.
A time dilatation experiment based on the Mössbauer effect

Some experiments are described in which the time dilatation at the tip of a high speed rotor is measured and compared with the expectations of relativity theory. Mossbauer sources and absorbers are attached to the centre and tip (or vice versa) of the rotor and the time dilatation deduced from the variation of gamma ray transmission with rotor speed. A technique is described whereby using a source absorber combination with an appropriate inherent frequency shift the experiment takes on the features of a null experiment. A result 2.1% ± 1.9% in excess of the expected dilatation is obtained.
Wireless Multi-Casting for Wideband Millimeter-Wave System With 1-bit DAC

Wireless multi-casting is an efficient transmission modality for downlink network control and content sharing. Conventional multi-casting amounts to finding an optimized beamforming vector under a specific performance metric and without the need of a dedicated treatment at the receiver. However, the so-called one-fit-all strategy is not directly applicable to mmWave systems equipped with 1-bit digital-to-analog converters (DAC), prompting us to develop a new multi-casting framework. The overarching design is built upon a vector-based instead of a scalar-based modulation, with which the multi-casting exhibits special features on both the transmitter and receiver. Specifically, we start by revealing the theoretical fundamentals for multi-casting under different 1-bit setups. Then, we design an iterative scheme to generate high-order constellations by establishing the equivalence between the codeword basis and low-order constellations. Finally, effective detection solutions are individually proposed for low-order and high-order constellations per their specific signal structures. Extensive analyses and simulations have been carried out to corroborate the decency of the proposed multi-casting strategy.
The Intestinal Immune Defense System in Insects

Over a long period of evolution, insects have developed unique intestinal defenses against invasion by foreign microorganisms, including physical defenses and immune responses. The physical defenses of the insect gut consist mainly of the peritrophic matrix (PM) and mucus layer, which are the first barriers to pathogens. Gut microbes also prevent the colonization of pathogens. Importantly, the immune-deficiency (Imd) pathways produce antimicrobial peptides to eliminate pathogens; mechanisms related to reactive oxygen species are another important pathway for insect intestinal immunity. The janus kinase/STAT signaling pathway is involved in intestinal immunity by producing bactericidal substances and regulating tissue repair. Melanization can produce many bactericidal active substances into the intestine; meanwhile, there are multiple responses in the intestine to fight against viral and parasitic infections. Furthermore, intestinal stem cells (ISCs) are also indispensable in intestinal immunity. Only the coordinated combination of the intestinal immune defense system and intestinal tissue renewal can effectively defend against pathogenic microorganisms.
EFFECTS OF ACCOUNTING INFORMATION SYSTEM ON THE SUSTAINABILITY OF SMEs IN LAGOS STATE, NIGERIA

The paper investigates the effects of accounting information systems on the sustainability of SMEs in a competitive environment. SMEs are known for inconsistent information preparation and presentation due to their lack of accountability skills the paper adopted a survey research design. However, the objectives of the paper are the investigation the relationship between the accounting information technology and decision making of SMEs; establish the relationships between the manual accounting system and the sustainability of SMEs, and examine the influence of the manual accounting system on accounting information of SMEs. Two research hypotheses were formulated and tested statistics tools such as regression and correlation tests and research questions formulated in line with the objective stated were formulated to achieve the aim of the study. Two hundred and ten copies (210) of a purposely designed questionnaire were distributed to the selected SMEs in Lagos state as of 31 December 2021 and analyzed using regression and correlation tests. Findings showed that there is a significant relationship between accounting information technology and the decision-making of SMEs. Also, there exists a significant relationship between the manual accounting system and the sustainability of SMEs in a competitive environment. The paper concludes that the application of accounting information systems significantly enhances the survival of SMEs in a competitive environment and should be harmonized with manual accounting systems. It was however recommended that software and hardware technologies should be used complementarily to generate quality accounting information for SMEs' decisions in Lagos State, Nigeria.

The paper presents two 5 GHz most recently obtained VLBI images of the nucleus of the quasar 3C 345 (being observed since 1977), which were obtained in 1989 and 1990 with 4 pc resolution. The images show a variety of morphological features in the jet, which can help to understand the dynamics of the central energy source and the transport of energy along the jet. Also presented are the analysis of the images, temporal variations, and the jet profile. The jet speed and the orientation of 3C 345 were determined from various observational constraints, within the framework of the relativistic twin-jet model. 46 refs.
Non-linear synchrotron self-Compton cooling of relativistic electrons

The broad-band spectral energy distributions (SEDs) of blazars exhibit two broad spectral components which in leptonic emission models are attributed to synchrotron radiation and synchrotron self-Compton (SSC) radiation of relativistic electrons. During high-state phases, the high-frequency SSC component dominates over the low-frequency synchrotron component implying that the inverse Compton SSC losses of electrons are at least equal or greater than the synchrotron losses of electrons. The linear synchrotron cooling, included routinely in radiation models of blazars, then has to be replaced by the SSC cooling. It is shown that the SSC energy-loss rate of electrons calculated in the Thomson limit (SST cooling) depends on an energy integral of the actual electron spectrum, reflecting the dependence of the energy density of the target synchrotron photons on the differential electron energy spectrum. The dependence of the SST loss rate on the initial kinetic energy of injected electrons is a collective effect completely different from the linear synchrotron cooling case. For the illustrative case of instantaneous injection of monoenergetic particles, we solve the non-linear kinetic equation for the intrinsic temporal evolution of the relativistic particles under SST cooling and compare the solution with the standard linear synchrotron cooling solution. For standard blazar emission region parameters, we find that under SST cooling electrons cool much more rapidly than in linear synchrotron cooling. The different cooling behaviour of electrons implies differences for the optically thin synchrotron and SSC radiation intensity and fluence energy spectra. The first difference concerns the duration of the SSC flare at different scattered photon energies. At large SSC photon energies, the SST cooled duration time is much smaller than the synchrotron cooled duration time, whereas at small SSC photon energies the SST cooled flare lasts much longer than the synchrotron cooled flare. Secondly, strong differences in the spectral behaviour of the total SSC fluence occur. At low scattered photon energies, the synchrotron cooled total SSC fluence exhibits a flatter (∝ k s -1/4 ) power-law behaviour than the SST cooled total SSC fluence (∝ k s -3/4 ). Thirdly, the SST cooled total synchrotron fluence exhibits a steeper (by Δα = 1) power-law behaviour [F T (∈) ∝ ∈ -3/2 ] than the synchrotron cooled total synchrotron fluence [F s (∈) ∝ ∈ -1/2 ] below the same exponential cut-off energy. These predictions of spectral behaviour with time and frequency provide conclusive tests for the presence or absence of linear synchrotron cooling or non-linear SST cooling in flaring non-thermal sources.

Une transition de phase ferro-antiferromagnetique a ete observee sur les deux echantillons. La temperature de transition montre une forte dependance vis a vis de la methode de preparation. A basse temperature, ces echantillons possedent une structure en helice du type MnP. On observe aussi une forte dependance du vecteur d'onde k avec la temperature. Investigations are made of the magnetic structure of MnCoSi. With different preparation techniques two different samples of CoMnSi are obtained. In both the specimens a phase transition, ferromagnetic to antiferromagnetic, is observed. The transition temperature depends on the preparation method of the samples. At low temperatures in both the samples a helix structure of MnP-type is found. The propagation vector k is found to be temperature dependent.
Velocity relaxation of an ellipsoid immersed in a viscous incompressible fluid

The motion of an ellipsoid in a viscous incompressible fluid, caused by a small time-dependent applied force, is studied on the basis of the linearized Navier-Stokes equations in terms of the frequency-dependence of the friction tensor. The asymptotic behavior of the hydrodynamic force at high frequency contains a term linear in frequency, with an added mass coefficient, and a term proportional to the square root of frequency, with a Basset coefficient. The latter is calculated from an expression derived by Batchelor [An Introduction to Fluid Dynamics (Cambridge University Press, Cambridge, 1967)]. A simple approximate three-pole expression is proposed for the frequency-dependent admittance for each principal direction, embodying added mass, particle mass, the steady state friction coefficient, and the Basset coefficient. It is suggested that a remaining unknown coefficient in the expression be determined by experiment, computer simulation, or numerical solution of an integral equation derived by Pozrikid.

Abstract Minimax estimation procedures for the mean vector of a distribution on a compact set under squared error type loss functions are considered. In particular, a Dirichlet process prior is used to show that a linear function of is a minimax estimator in the class of all measurable estimators and all possible distributions. This effort extends some earlier work of Bühlmann to a more general setting.
Towards Greener and More Sustainable Synthesis of MXenes: A Review

The unique properties of MXenes have been deemed to be of significant interest in various emerging applications. However, MXenes provide a major drawback involving environmentally harmful and toxic substances for its general fabrication in large-scale production and employing a high-temperature solid-state reaction followed by selective etching. Meanwhile, how MXenes are synthesized is essential in directing their end uses. Therefore, making strategic approaches to synthesize greener, safer, more sustainable, and more environmentally friendly MXenes is imperative to commercialize at a competitive price. With increasing reports of green synthesis that promote advanced technologies and non-toxic agents, it is critical to compile, summarize, and synthesize the latest development of the green-related technology of MXenes. We review the recent progress of greener, safer, and more sustainable MXene synthesis with a focus on the fundamental synthetic process, the mechanism, and the general advantages, and the emphasis on the MXene properties inherited from such green synthesis techniques. The emerging use of the so-called green MXenes in energy conversion and storage, environmental remediation, and biomedical applications is presented. Finally, the remaining challenges and prospects of greener MXene synthesis are discussed.
