Abstract

Objectives
Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder characterized by impaired activity of the enzyme required for cortisol and aldosterone production, resulting in increased adrenal androgen synthesis. Factors affecting fertility in CAH patients include ambiguous genitalia and their complications, excessive androgen secretion, adrenal progesterone hypersecretion, and various psychosocial factors. Serum anti-Müllerian hormone (AMH) level is used to assess ovarian reserve in women. A few data on serum AMH levels in CAH patients are available in the literature. The aim of the study was to evaluate ovarian reserve in a group of post-menarche females diagnosed with CAH by measuring serum AMH level and assessing the number of antral follicles sonographically.

Methods
A case-control study was conducted on 17 post-pubertal CAH females and 17 age-matched healthy female controls; the mean age of the patient group was 15.09 ± 3.55 years ranging from 11 to 24 years, while the mean age of the control group was 16.04 ± 3.72 years ranging from 12 to 25 years, the mean post-menarchal age of the patients group was 3.29 ± 1.37 years ranging from 1 to 6 years while the mean post-menarchal age of the control group was 4.13 ± 1.62 years ranging from 1 to 9 years. The degree of hirsutism was compared between the two groups according to the modified Ferriman-Gallwey score, clitoral length was assessed using a digital caliber. Serum levels of adrenal androgens in addition to basal levels of serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, and serum AMH were measured in both groups.

Results
Patients had smaller uterine volumes, and smaller ovarian volumes but a comparable number of antral follicles and comparable serum AMH levels relative to controls.

Conclusions
Good compliance with treatment in patients with CAH results in good hormonal control, low risk of PCOS, good fertility parameters, and a good ovarian reserve.

Abstract
Amorphous aerogels with the microscopic nanoscale three-dimensional meshes provide superb platforms for investigating unique physicochemical properties. In order to enhance the physical, thermal and mechanical performances, one efficient and common approach is integrating diverse functional materials. Herein, we report a simple strategy to fabricate the amorphous silicon doped Y2O3 aerogels with the post-gelation method under the N2/EtOH supercritical atmosphere. The impact of Si concentration on the nonlinear optical properties is investigated for the first time. The maximum modulation depth is 1.65 % with a saturation intensity of 0.78 MW cm−2 with the 1-ps laser excitation at 1590 nm. Finally, we incorporated the silicon-doped Y2O3 aerogel based saturable absorber (SA) into an erbium-doped fiber laser (EDFL) and achieved various mode-locking operations at different wavelengths in the super C band, in terms of the conventional soliton, harmonic soliton molecules pulses, and dual-wavelength soliton mode-locking. Overall, this work confirms that amorphous silicon-doped Y2O3 aerogels are good nonlinear optical materials and pave a way for the ultrafast photonic and nonlinear optical applications with amorphous materials in near future.

Published: March 2024

Abstract
Fractional diffusion partial differential equation (PDE) models are used to describe anomalous transport phenomena in fractal porous media, where traditional diffusion models may not be applicable due to the presence of long-range dependencies and non-local behaviors. This study presents an efficient hybrid meshless method to the compute numerical solution of a two-dimensional multiterm time-fractional convection-diffusion equation. The proposed meshless method employs multiquadric-cubic radial basis functions for the spatial derivatives, and the Liouville-Caputo derivative technique is used for the time derivative portion of the model equation. The accuracy of the method is evaluated using error norms, and a comparison is made with the exact solution. The numerical results demonstrate that the suggested approach achieves better accuracy and computationally efficient performance.

Abstract
The heat and mass transportation for nanofluid across a swirling cylinder under the actions of magnetic effects and Cattaneo–Christov heat flux is reported in the current analysis. The objective of this study is to examine the energy and mass transmissions through hybrid nanofluid under the influence of heat source/sink and reactive species. The hybrid nanoliquid has been prepared by the dispersion of silver (Ag) and gold (Au) nanoparticles (NPs) in the base fluid ethylene glycol (C2H6O2). The flow phenomena are expressed in the form of nonlinear partial differential equations and are converted to a nondimensional form, by employing the similarity substitution. For the computational estimation of the problem, the parametric continuation method is employed. The demonstration of velocity, mass, and energy outlines versus distinct physical factors is exposed in the form of figures. It has been perceived that the axial and swirling velocity outline drops with the influence of the Reynolds number, magnetic effect, and the insertion of Au and Ag NPs in C2H6O2. Furthermore, the hybrid nanofluid energy curve declines with the effect of the Reynolds number, thermal relaxation factor, and the volume friction of NPs.
Study on influencing factors and regularity analysis of eddy current method applied to detection of reinforcement corrosion

Published: March 2024

Abstract
Rebar corrosion is one of the main reasons for the deterioration of concrete structures. In order to ensure the safe operation of reinforced concrete structures, it is necessary to detect the corrosion rate of rebars in time. This article adopts the eddy current method based on electromagnetic induction to detect steel corrosion, studies the mechanism of alternating current (AC) impedance change induced by steel corrosion in coils, and establishes a mathematical model between steel corrosion and coil AC impedance. Meanwhile, the quantitative relationship between excitation signal frequency, concrete thickness, coil parameters, and coil impedance is studied. Through experiments, it was found that in the early stages of steel corrosion, there is a linear relationship between the scanning peak value of the coil impedance and the mass loss rate of the steel bars, and the slope of the fitting curve decays exponentially with the increase of the concrete thickness. The method used in this paper has an absolute error of less than 0.01 and a relative error of less than 8 % in detecting the mass loss rate of rebars at the initial stage of steel corrosion. When the concrete thickness is less than 20 mm, the relative error is lower than 4 %.
Experience(s) of Decorporation: The Invisibilisation of Care in John Lanchester’s Capital (2012)
Authors: Borrego Alice 
Published: March 2024

Abstract
In The Ethics of Care (2006), Virginia Held underlines that care cannot be conceived without recognising our interdependence and responsibility for one another. Despite recent efforts to divide our society between private and public spheres, no such clear delimitation is possible in the ethics of care. Yet, as the Covid-19 pandemic has shown, the neoliberal financialisation of healthcare systems is redefining our ability to look after others. John Lanchester’s ‘crunch lit’ novel Capital (2012) draws attention to what I call “experiences of decorporation”: the vulnerable ageing body and the medical system both become victims of a market-logic which invisibilises the cared for, the carer, and the caring. Taking place on a single street in London, the metonymic construction of the novel calls for an analysis of how the illness and death of Petunia Howe, the oldest resident on Pepys Road, is symptomatic of the ethical effacement of the body politic under the clout of neoliberal politics.
Spatially Dependent Seismic Wavefield Scattering from an Underground Chemical Explosion: Analysis of the Source Physics Experiment Dry Alluvium Geology Large-N Array
Authors: Darrh Andréa , Bodmer Miles , Poppeliers Christian 
Published: March 2024

ABSTRACT
Explosion sources have been observed to generate significant shear-wave energy despite their isotropic nature. To investigate this phenomenon, we conduct an analysis of the seismic data collected as part of the Source Physics Experiment (SPE): Dry Alluvium Geology (DAG) and investigate the generation of shear-wave energy via scattering. The data were produced by three underground chemical explosions and consist of three-component seismograms, which were recorded by the DAG Large-N array. Synthetic tests suggest that for the DAG experiments, small-scale stochastic heterogeneities, defined as features with correlation lengths of 10–100s of meters, are more effective than large-scale geologic structure (scales &gt;1–10 km) at reproducing the scattering of explosion generated wavefields observed at DAG. We analyze the seismic data for spatially variable ratios between transversely and radially polarized seismic energy, and then estimate the mean free path of P and S waves. All analyses are conducted within a frequency band of 5–50 Hz. The ratio of transversely to radially polarized energy is the highest in the east and west portion of the Large-N array. In addition, the magnitude of the estimated S-wave mean free path is shorter in the eastern portion of the Large-N array. This variation indicates that the eastern area of the DAG array is where more scattering is occurring, suggesting azimuthal dependence of P-to-P and P-to-S scattering. This azimuthal dependence of P-to-S scattering can have implications for explosion discrimination based on spectral ratios of seismic wave types, because the general assumption is that explosions do not generate shear-wave energy. Synthetic tests modeling only larger-scale geologic structure had lower transversely polarized energy (only four stations showing a transversely to radially polarized energy ratio greater than 1) and fewer stations (&lt;10) displaying shorter (&lt;300 m) mean free paths than what was observed in the DAG data results.

Melasma, is a chronic acquired disorder of hypermelanosis of skin which is exposed to ultraviolet radiation. The clinical presentation is most often in the form of hyperpigmented patches over the face in three common patterns: Centrofacial, malar and mandibular. It is commonly seen in pigmented skin phenotypes (Fitzpatrick skin types III-V). The disease has an impact on the quality of life of patients. Dermoscopy is an in vivo noninvasive technique used to examine pigmented and amelanotic skin lesions. The technique is performed using a hand-held self-illuminating device called dermatoscope that visualizes features present under the skin surface.: To study dermoscopic (dermatoscopic) features of melasma and to distinguish between epidermal and dermal melasma based on dermoscopic features.: This study was conducted in an OPD in a clinic on 40 patients of melasma. Dermoscopy was done and their dermatoscopic features were recorded, melasma was classified as epidermal or dermal depending on dermatoscopic features.: Dermatoscopic features of melasma seen were – Accentuation of pseudoreticular pigment network, light to dark brown in colour sparing of the periappendageal region (follicular and sweat gland openings), brown granules, blue- gray perifollicular accentuation honeycomb like reticular pattern and arcuate pigmented lines. 18 patients (45%) showed epidermal type 9 patients (22.5%) revealed dermal type of melasma, 13 patients showed mixed features (epidermal and dermal). Melasma with steroid abuse showed marked erythema and telangiectasia.Dermatoscope is a valuable aid to diagnose, classify and to monitor treatment of melasma.

Teza o zmierzchu krytyki powraca od końca lat 90., czyli od zmiany paradygmatu kultury z analogowego na cyfrowy, która doprowadziła też do zmian w obiegu krytycznym na rzecz elektronicznego i amatorskiego, co odbyło się kosztem obiegu tradycyjnego (prasowego) i elitarności zawodu krytyka. Początek XXI wieku zaowocował diagnozami stanu krytyki literackiej, filmowej, teatralnej, ale nie znajduję żadnej publikacji, która ukazałaby to zjawisko w tak szerokiej gamie: od ujęcia językoznawczego, przez krytykę literacką i filmową, kuratorsko-artystyczną i krytyki instytucji, po krytykę gier planszowych.

Passive Eversion Assessment for Progressive Collapsing Foot Deformity After Lateral Column Lengthening
Authors: Kim Jaeyoung , Hoffman Jeffrey W. , Ellis Scott J. , Deland Jonathan T. , Steineman Brett D. 
Published: March 2024

Background:
Reduced hindfoot eversion motion has been proposed as a cause of increased lateral foot pressure following lateral column lengthening (LCL) for progressive collapsing foot deformity (PCFD). A subjective intraoperative assessment of passive eversion has been suggested to help evaluate correction; however, it is unclear how passive eversion correlates with objective measurements of foot stiffness. Our objectives were to quantify the relationship between the maximum passive eversion in hindfoot joints following LCL with plantar pressure during stance and to determine the influence of wedge size on these outcomes.

Methods:
Ten cadaveric specimens extending from the mid-tibia distally were tested on a 6-degrees-of-freedom robot to simulate the stance phase of level walking. Five conditions were tested: intact, simulated PCFD, and 3 LCL wedge conditions (4, 6, and 8 mm). Outcomes included the lateral-to-medial forefoot plantar pressure (LM) ratio during stance and the maximum passive eversion measured in the hindfoot joints. Simple linear regressions were performed to evaluate relationships between outcomes and wedge sizes.

Results:
A strong negative relationship was found between passive subtalar eversion and the LM ratio during stance (r[38] = −0.46; p = 0.0007), but not between passive talonavicular eversion and the LM ratio (r[38] = −0.02; p = 0.37). Wedge size was strongly related to subtalar eversion (r[38] = −0.77; p < 0.0001), talonavicular eversion (r[38] = −0.55; p = 0.0003), and the LM ratio (r[38] = 0.70; p < 0.0001). Increased wedge size resulted in average decreases in subtalar and talonavicular eversion of 1.0° (95% confidence interval [CI]: 0.8° to 1.3°) and 1.2° (95% CI: 0.6° to 1.6°), respectively. Increased wedge size also increased the LM ratio by 0.38 (95% CI: 0.25 to 0.50), indicating a lateral shift in plantar pressure.

Conclusions:
Decreased hindfoot eversion following LCL was related to increased lateral plantar pressure during stance. Increasing wedge size correlated with decreasing passive hindfoot eversion and increasing lateral plantar pressure, suggesting that intraoperative preservation of eversion motion may be important for preventing excessive lateral loading.

Clinical Relevance:
To avoid overcorrection or undercorrection of the deformity, hindfoot eversion assessment in addition to radiographic evaluation may be important for optimizing the amount of lengthening to achieve successful LCL.

Abstract
Hydraulic fracturing is a promising way to increase oil recovery in tight reservoirs. The accurate assessment of the expansion of fracture networks within the reservoir is a prominent challenge encountered in hydraulic fracturing operations. To overcome this obstacle, the incorporation of tracer injection along with the fracturing fluids and flowback analysis provides fundamental knowledge for reservoir characterization. Herein, a magnetic Pickering nanoemulsion is introduced as a potential tracer for hydraulic fracturing applications. In this regard, the transportation behavior of this particular Pickering nanoemulsion is a crucial factor for designing and optimizing its implementation in energy, sustainability, and environmental areas. In this study, a polymer-coated iron oxide (Fe3O4) nanoparticle (NP) was synthesized and utilized as a stabilizer to form stable oil-in-water (O/W) nanoemulsions. Two different types of nanoemulsions (with the highest and the lowest stability) were then fabricated with various ratios of polymer shell to Fe3O4 nanoparticle core (3:1 and 0.5:1). Core flooding experiments were then performed in a sandpack to evaluate the stability and retention behavior of the synthesized nanoemulsions in porous media. The nanoemulsion flow profiles were quantitatively monitored by X-ray CT scanning and sandpack magnetic susceptibility experiments. In addition, the density of the nanoemulsion effluents and pressure drop during the whole flooding process were measured to evaluate the most effective nanoemulsion formulation with the lowest retention in the porous media. According to the obtained results, the most stable nanoemulsion formulation with the highest polymer-to-nanoparticle coating ratio (3:1) was transported through the sandpack effortlessly with the lowest retention. The pressure-drop results also showed a gradual increase of pressure during nanoemulsion flooding due to the drag force and higher viscosity of the nanoemulsions compared to water. However, throughout the chase water flooding, the nanoemulsion with the highest stability was displaced piston-like along the sandpack with lower pressure drop, implying lower retention of the nanoemulsion at the higher ratio of polymer to nanoparticle coating.

Abstract
In this study, a self-designed microchip system was used to visually study the pore-scale salt crystallization and migration, and a high-performance optical microscope was used to dynamically observe the salt precipitation process and results. The results show that pore-scale salt crystals mainly precipitate in the residual water phase, and mainly present two forms of occurrence, large-grained salt crystals and small-grained aggregated crystals, respectively. In addition to growing in the brine phase, large-grained salt crystals also nucleate and grow at the gas-liquid interface, and the maximum salt crystal size can reach the order of the pore size. This phenomenon was discovered for the first time and has not been mentioned in the existing literature. In addition, this study also observed an interesting phenomenon. The salt crystals formed in the wetting brine film and the brine phase can migrate under the combined influence of displacement pressure and capillary force, and eventually accumulate and precipitate inside the pores. Injection flow rate and salinity have a strong influence on the pore-scale salt crystallization kinetics. There is a critical value for the injection flow rate, and the critical injection rate causes the salt precipitation to be significantly aggravated. Under the same injection flow rate, an increase in salinity leads to an increase in the amount of salt precipitation.
Integrated Characterization of Expanding-Solvent Steam-Assisted Gravity Drainage (ES-SAGD) Processes by Using a Heat-Penetration Criterion within a Unified, Consistent, and Efficient Framework
Authors: Yang Shikai , Yang Daoyong 
Published: March 2024

Abstract
The hybrid solvent-steam injection (e.g., expanding-solvent steam-assisted gravity drainage (ES-SAGD) is the most promising method to enhance heavy oil recovery (EOR); however, it is a quite a challenge to reproduce the experimental measurements and in-situ observations because of the complicated multiphase flow behaviour resulted from the coupled mass and heat transfer. In this work, an integrated technique has been developed and applied for the first time to dynamically and accurately characterize an ES-SAGD process within a unified, consistent, and efficient framework. By taking the competitive impact between heat energy and solvent dissolution, a generalized heat-penetration (HP) criterion has been derived and integrated with a numerical simulator to characterize the dynamics of solvent/steam chamber propagation conditioned to the production profiles during hybrid solvent-steam processes. This generalized HP criterion allows us to not only dynamically calculate temperature profiles beyond a solvent/steam chamber interface (SCI), but also accurately and pragmatically quantify mass and heat transfer inside the diluted oil drainage zone as well as the solvent/steam chamber. Also, comprehensive effects of the thermally sensitive co/counter-current flows are examined with a series of multiphase relative permeabilities. Such an integrated technique has been successfully validated by reproducing the measured solvent/steam chambers in 3D physical ES-SAGD experiments. Good agreements between the simulated and measured production profiles (i.e., injection temperature, pressure, and flow rate) have been made throughout the entire production period. Not only have the measured solvent/steam chambers been reproduced, but also sensitivity analyses have been performed to investigate the influences of multiphase flow behaviour, solvent concentration, and grid dimension. It is found that the diffusion/dispersion coefficients and thermal properties are dependent on temperature and solvent concentrations, competitively affecting the calculated temperature distributions. Moreover, gas-liquid relative permeabilities can impose a significant impact on the SCI moving velocity as well as the oil drainage front. Such an integrated approach considerably reduces the simulation uncertainties and complexities, offering a straightforward and effective means of dynamically reproducing the observed solvent/steam chambers within a unified, consistent, and efficient framework.
