A Home-Based Approach to Auditory Brainstem Response Measurement: Proof-of-Concept and Practical Guidelines
Authors: Parker Ashley , Skoe Erika , Tecoulesco Lee , Naigles Letitia 
Published: October 2022

AbstractBroad-scale neuroscientific investigations of diverse human populations are difficult to implement. This is because the primary neuroimaging methods (magnetic resonance imaging, electroencephalography [EEG]) historically have not been portable, and participants may be unable or unwilling to travel to test sites. Miniaturization of EEG technologies has now opened the door to neuroscientific fieldwork, allowing for easier access to under-represented populations. Recent efforts to conduct auditory neuroscience outside a laboratory setting are reviewed and then an in-home technique for recording auditory brainstem responses (ABRs) and frequency-following responses (FFRs) in a home setting is introduced. As a proof of concept, we have conducted two in-home electrophysiological studies: one in 27 children aged 6 to 16 years (13 with autism spectrum disorder) and another in 12 young adults aged 18 to 27 years, using portable electrophysiological equipment to record ABRs and FFRs to click and speech stimuli, spanning rural and urban and multiple homes and testers. We validate our fieldwork approach by presenting waveforms and data on latencies and signal-to-noise ratio. Our findings demonstrate the feasibility and utility of home-based ABR/FFR techniques, paving the course for larger fieldwork investigations of populations that are difficult to test or recruit. We conclude this tutorial with practical tips and guidelines for recording ABRs and FFRs in the field and discuss possible clinical and research applications of this approach.

Published: October 2022

AbstractLittle is known about objective classifying of noise exposure risk levels in personal listening device (PLD) users and electrophysiologic evidence of cochlear synaptopathy at very fast click rates. The aim of the study was to objectively classify noise exposure risk using iPhone Health app and identify signs of cochlear synaptopathy using behavioral and electrophysiologic measures. Thirty normal-hearing females (aged 18–26 years) were grouped based on their iPhone Health app's 6-month listening level and noise exposure data into low-risk and high-risk groups. They were assessed using a questionnaire, extended high-frequency (EHF) audiometry, QuickSIN test, distortion-product otoacoustic emission (DPOAE), and simultaneous recording of electrocochleography (ECochG) and auditory brainstem response (ABR) at three click rates (19.5/s, 97.7/s, 234.4/s). A series of ANOVAs and independent samples t-test were conducted for group comparison. Both groups had within-normal EHF hearing thresholds and DPOAEs. However, the high-risk participants were over twice as likely to suffer from tinnitus, had abnormally large summating potential to action potential amplitude and area ratios at fast rates, and had slightly smaller waves I and V amplitudes. The high-risk group demonstrated a profile of behavioral and objective signs of cochlear synaptopathy based on ECochG and ABR recordings at fast click rates. The findings in this study suggest that the iPhone Health app may be a useful tool for further investigation into cochlear synaptopathy in PLD users.
Translational Applications of Machine Learning in Auditory Electrophysiology
Authors: Smith Spencer 
Published: October 2022

AbstractMachine learning (ML) is transforming nearly every aspect of modern life including medicine and its subfields, such as hearing science. This article presents a brief conceptual overview of selected ML approaches and describes how these techniques are being applied to outstanding problems in hearing science, with a particular focus on auditory evoked potentials (AEPs). Two vignettes are presented in which ML is used to analyze subcortical AEP data. The first vignette demonstrates how ML can be used to determine if auditory learning has influenced auditory neurophysiologic function. The second vignette demonstrates how ML analysis of AEPs may be useful in determining whether hearing devices are optimized for discriminating speech sounds.
Implementation of Machine Learning on Human Frequency-Following Responses: A Tutorial
Authors: Jeng Fuh-Cherng , Jeng Yu-Shiang 
Published: October 2022

AbstractThe frequency-following response (FFR) provides enriched information on how acoustic stimuli are processed in the human brain. Based on recent studies, machine learning techniques have demonstrated great utility in modeling human FFRs. This tutorial focuses on the fundamental principles, algorithmic designs, and custom implementations of several supervised models (linear regression, logistic regression, k-nearest neighbors, support vector machines) and an unsupervised model (k-means clustering). Other useful machine learning tools (Markov chains, dimensionality reduction, principal components analysis, nonnegative matrix factorization, and neural networks) are discussed as well. Each model's applicability and its pros and cons are explained. The choice of a suitable model is highly dependent on the research question, FFR recordings, target variables, extracted features, and their data types. To promote understanding, an example project implemented in Python is provided, which demonstrates practical usage of several of the discussed models on a sample dataset of six FFR features and a target response label.
Can Pelvic Orientation Be Accurately Predicted Using One Radiographic View Alone?

Published: October 2022

AbstractPelvic positioning during total hip arthroplasty (THA) can affect the functional position of the acetabular component. A comprehensive understanding of pelvic orientation before THA is necessary to allow for proper cup positioning and mitigate the risks of postoperative complications. Measurements using anteroposterior (AP) radiographs have been described as an effective means of accurately predicting pelvic functional orientation. The purpose of our study was to describe the accuracy of assessing pelvic tilt using AP radiographs alone. An online survey was created and sent to a cohort of fellowship-trained adult reconstruction (AR) surgeons. The survey consisted of 65 standing AP pelvis radiographs. Participants were asked to score each radiograph as (1) anterior pelvic tilt more than 10 degrees, (2) posterior pelvic tilt more than 10 degrees, or (3) neutral. Responses were then compared with measurements of pelvic tilt made on lateral standing pelvic radiographs. Demographic data, such as country of practice, surgical volume, surgical approach, familiarity with spinopelvic mobility, and planning with spinopelvic mobility were evaluated. Categorical variables were compared using chi-squared analysis and analysis of variance. Continuous variables were assessed using unpaired, two-tailed Student's t-tests. A total of 45 surgeons completed the survey. The average correct predictive value of pelvic tilt between all surgeons was 53.2%. Of the responding surgeons, 51.2% performed greater than 100 cases per year. Fifty percent of surgeons reported that they were “not so familiar” or “somewhat familiar” with the principles of spinopelvic mobility. Also, 43.5% of surgeons reported that they did not routinely use spinopelvic mobility principles in THA planning. Pelvic orientation before THA is poorly predicted in our cohort of surveyed fellowship-trained AR surgeons with standing AP pelvis radiographs alone. Given the limited understanding of these principles within our cohort, preoperative evaluation of spinopelvic parameters with AP radiographs may require supplementation with lateral pelvic views to ensure detailed assessment and accurate preoperative planning. This is a prospective survey study and reflects level of evidence II.
Building Research Initiatives by Developing Group Effort (BRIDGE): Patient-Partners in Aphasia Research
Authors: Brice Alejandro , Hinckley Jacqueline 
Published: October 2022

AbstractResearcher-initiated research often has little or no input from the groups who will be affected by the results of the research. The aim of this project was to describe practices of embracing patient-partners (i.e., individuals with aphasia and spouses/family members) in research. Six webinars were developed for both researchers and patient-partners that were required prior to participating in a joint conference that focused on collaborative research teams. The conference was designed based on an appreciative inquiry approach. Including patient-partners into research priorities and planning has been accomplished across various health domains in the United States, but this was the first organized national effort, in the United States, to support the inclusion of people with aphasia and their families as active partners in the research process. Consequently, it is hoped that future aphasia researchers also include patient-partner teams into their research process for more ecologically valid outcomes.
Urinary Nephrin is a Sensitive Marker to Predict Early Onset of Nephropathy in Type 2 Diabetes Mellitus
Authors: Veluri Ganesh , Mannangatti Murugan 
Published: October 2022

Abstract
Objective The present study has been designed to evaluate urinary nephrin that best predicts the occurrence of renal dysfunction in type 2 diabetes mellitus patients and its correlation with clinical parameters of nephropathy.
Materials and Methods A total of 80 type 2 diabetes mellitus and 40 age- and gender-matched healthy controls were recruited. Biochemical and clinical parameters were analyzed in all the study participants. Analysis of variance was performed to compare the differences between the groups. Pearson's correlation analysis was used to analyze the association of nephrin with clinical parameters of nephropathy. Receiver operating characteristic curves were constructed to study the diagnostic accuracy of markers to identify diabetic nephropathy.
Results The levels of nephrin were significantly elevated in both groups of type 2 diabetes mellitus patients when compared with healthy individuals (p = 0.0001). The urinary nephrin was positively correlated with hemoglobin A1c and urinary albumin creatinine ratio (r = 0.520, 0.657, p < 0.0001) and negatively correlated with estimated glomerular filtration rate (r = –0.539, p < 0.0001). The diagnostic sensitivity and specificity of nephrin for nephropathy were 100 and 88%, respectively, and urinary albumin creatinine ratio was 43 and 76%, respectively.
Conclusion The study findings suggest that nephrin levels are strongly and positively associated with nephropathy in type 2 diabetes mellitus patients and it has a greater potential to be an early predictable marker of nephropathy than urinary albumin creatinine ratio.

The ITER Collective Thomson scattering (CTS) diagnostic will measure the dynamics of fusion-born alpha particles in the burning ITER plasma by scattering a 1 MW 60 GHz gyrotron beam off fast-ion induced fluctuations in the plasma. The diagnostic will have seven measurement volumes across the ITER cross section and will resolve the alpha particle energies in the range from 300 keV to 3.5 MeV; importantly, the CTS diagnostic is the only diagnostic capable of measuring confined alpha particles for energies below ∼1.7 MeV and will also be sensitive to the other fast-ion populations. The temporal resolution is 100 ms, allowing the capture of dynamics on that timescale, and the typical spatial resolution is 10–50 cm. The development and design of the in-vessel and primary parts of the CTS diagnostic has been completed. This marks the beginning of a new phase of preparation to maximize the scientific benefit of the diagnostic, e.g., by investigating the capability to contribute to the determination of the fuel-ion ratio and the bulk ion temperature as well as integrating data analysis with other fast-ion and bulk-ion diagnostics.
CFD Applied to the Analysis of the Operation of a Solar Still Pyramidal-type
Authors: Terres H , Chávez S , Lizardi A , Lara A , Morales J , Rodríguez R , Ruiz C 
Published: October 2022

Abstract
This work shows the results obtained for the temperature distributions of the component elements of a pyramidal type solar still. The results of the air velocity and density distributions inside the still are also shown. The results indicate which are and where the maximum values of temperature, density, and airspeed are located. These results are useful because they help to establish how the geometry of the still influences its operating process. The study by the CFD technique turns out to be very useful because it allows the formulation of design criteria regarding the geometry of the still and how they could make improvements in the use of solar energy in solar stills.
Study of Evaporative Heat and Mass Transfer in Solar Distillation
Authors: Chávez S , Terres H , Lizardi A , Lara A , Reyes M , Andrade E 
Published: October 2022

Abstract
In this work, the assessment of 3 experimental tests on a solar still is presented, where 4, 5 and 6 L of brine were utilized. Data of temperature in several parts of the device and of solar radiation were obtained, besides, the outlet volume water was measured every 5 minutes during a timelapse from 10:00 am to 18:00 pm, which is compared through a study of heat and mass transfer due to evaporation, with the aim of predicting de amount of distilled volume.
Experimental results show that 2.7, 2.2 and 1.8 L are distilled for the initial volumes of 4, 5 and 6 L, respectively. However, when Dunkle’s thermal model is applied, the resulting distilled volumes are 2.2 2 and 1.7 L for the initial volumes of 4,5 and 6 L, respectively. This analysis indicates that the chosen thermal model has an error of approximately 4% compared with experiments. However, this model can be used to estimate accurately the outlet volume of distilled fluid.
Bidimensional uncertainty product associated with two specific Gyrator domains
Authors: Vilardy Juan M , Perez Ronal , Torres Cesar O 
Published: October 2022

Abstract
The uncertainty principle for a two-dimensional signal, giving us a lower bound for the product of the spreads (uncertainty product) of the signal representations in two specific Gyrator domains (GDs), is developed and presented. The GDs are defined by the Gyrator transform (GT), which is a new mathematical tool for analysis and processing of two-dimensional signals belonging to the linear canonical transforms. The obtained lower bound for the uncertainty principle depends on the two rotation angles that define the two GDs of the two-dimensional signal. The resulting uncertainty principle could be used in image processing and applications based on the GT. Finally, we show that the uncertainty principle for the antisymmetric Fourier transform with a rotation of the coordinates at π/2 is a special case of the bidimensional uncertainty product associated with two specific GDs.
Thin films of titanium dioxide modified with MoO3 nanostructures for photocatalytic applications
Authors: Rodríguez Nava C E , Solis Casados D A , Romero S , Escobar Alarcón L 
Published: October 2022

Abstract
TiO2 thin films modified with MoO3 nanostructures were obtained by the spin coating technique. The precursors solutions were prepared by the sol-gel technique adding colloids of Mo-based nanostructures prepared by laser irradiation of powders suspended in liquid media. It was found that MoO3 layered nanostructures form the prepared colloidal solutions. The obtained films were characterized by X-Ray Photoelectron, Raman, Ultraviolet– Visible and PL Spectroscopies, and Scanning Electron Microscopy. XPS reveal the presence of TiO2 and MoO3 in the films. Raman results show that crystalline TiO2 in its anatase phase is obtained. These results indicate that the films are forming composites in which nanostructures of molybdenum trioxide are incorporated in the titania film. Optical measurements show that the band gap energy for all samples vary from 3.3 to 3.5 eV.
Analysis of the thermoluminescent glow curve of alumina matrices obtained under different sintering and cerium doped conditions
Authors: Rojas J , Cogollo R , Gutiérrez O 
Published: October 2022

Abstract
This work presents the deconvolution of thermoluminescent (TL) glow curves, by using logistic asymmetric functions, of sintered pure alumina matrices under two different conditions: 1000 °C/3h (NALO) and 1000 °C/6h (ALO), and also, of cerium-doped matrix with 0.1 wt.% sintered at 1000 °C/3h (NALOCe0.1). Sintering treatments induced a remarkable change in the TL kinetics and consequently in the glow curve shape, in terms of the number of traps and initially trapped charge carriers. Structural analysis revealed α-alumina phase in NALO and ALO matrices, and its distortion for NALOCe0.1, achieving a generation of new electronic traps energetically more stable for doped matrix. This result offers a possible solution in order to reduce the notable fading for TL characteristic peak in alumina matrix, expanding its field of applications.
Analytical calculation of τ(q) for multifractals
Authors: del Río Correa J L , López García J , Álvarez Ballesteros Y A 
Published: October 2022

Abstract
To find the Hausdorff dimensional spectrum that characterizes a multifractal, it is required to find the mass function τ(q), which is implicitly defined by the Halsey equation, which in general can only be solved numerically, however there are particular cases in which it is possible to find analytically τ(q) as a parametrically defined function. In this paper we present and discuss the Piña’s method to find analytically τ(q), the Hausdorff dimension spectrum of the multifractal is found.

Abstract
We analyze the multifractal decomposition of Moran fractals using the Olsen Multifractal Measure (OMM). We show that this measure is non-singular when the Halsey’s partition function takes the value 1, this result has two consequences, one of them defines the mass function τ(q), the other is that it also defines a statistical measure ν in terms of a probability vector
P
(q). The Hausdorff dimension f(q) of the concentration set of the measure ν is equal with the Holder exponent evaluated with the measure ν, this equality implies that f(q) = q
α(q) – τ(q). Finally, using the results of Cawley and Mauldin it is shown that D(α) = DimH

Unmonitored Cardiac Magnetic Resonance Imaging of rats at 7 T
Authors: Marrufo O , Solis Najera S E , Vazquez F , Martin R , Rodriguez A O 
Published: October 2022

Abstract
Unmonitored cardiac images of a rat were acquired using a standard gradient echo sequences to study the artefact ghosting mainly caused by heart and respiration motion. All imaging experiments were performed using a transceiver circular-shaped coil and a preclinical magnetic resonance imager at 7 T. Heart images showed the ghosting artefact along the frequency encoding direction. However the image quality was not drastically affected by this type of ghosting. These results showed that standard acquisition parameters may serve to establish a reference to study this unwanted artefact without ECG and respiratory gating and using a single-channel transceiver coil.

Authors: Guerrero Hernández L A , Flores Campos C R C , SanMiguel Torres 
Published: October 2022

Abstract
The accident data referring to deceased infants, who do not have a child restraint system that complies with safety devices, are alarming. Although the current child restraint systems present a good level of protection, it is possible to design systems that improve the performance of the current ones, the improvement in safety being the main motivation for this study. This child restraint system will be incorporated into a sedan car, taking into account the characteristics of the positioning and folding in the rear seat of a sedan vehicle. This research is organized in two phases: the first corresponds to the design of a folding infant carrier system prototype, and the second stage shows the operation of this mechanism through its verification focused on the kinematic study.

Authors: Barrera-Angeles A A , Barrera Hernández D , Gutiérrez-Márquez J G , López Valencia Alberto , Morales-Hernández A , Rivera-Montalvo T 
Published: October 2022

Abstract
Thermoluminescence properties of lanthanum aluminum oxide (LaAlO3) doped with optically active rare earth ions have been investigated for ultraviolet dosimetry purposes. LaAlO3:Pr3+ powder samples were doped with 2% of Pr3+, for the first research they show two thermoluminescent (TL) peaks at 215±5 °C and 340±4 °C which can be sensitized after 1 min to 12 min of UVA exposure. The material shows TL output and linear response for UVA lamp in 365 nm wavelength light. On the other hand, the powder samples that were irradiated with a UVC lamp at 254 nm, it also shows one peak and a shoulder, the maximum peak in a range that goes from 195 °C to 220 °C, in which the exposure time was varied from 5 to 30 seconds and the shoulder remains stable at 345± 8 ° C. The experiments demonstrates that LaAlO3: Pr3+ powders are very attractive to be investigated as UVA and UVC dosimeters.
