Design mode filtering interferometer using etched double clad fiber
Authors: Khamees Mohanad G. , Mansour Tahreer S. 
Published: July 2023

Abstract
Mode filtering technique is one of the most desired techniques in optical fiber communication systems, especially for multiple input multiple output (MIMO) coherent optical communications that have mode-dependent losses in communication channels. In this work, a special type of optical fiber sensing head was used, where it utilizes DCF13 that is made by Thorlabs and has two numerical apertures (NA’s). One is for core and 1st cladding region, while the 2nd relates the 1st cladding to the 2nd cladding. Etching process using 40 % hydro-fluoric (HF) acid was performed on the DCF13 with variable time in minutes. Investigation of the correlation between the degree of etching and the refractive index (RI) profile of double-clad fibers for low order linearly polarized (LP) modes is the focus of this work research. The used software programs to simulate the effect of etching are Comsol Multi-Physics V6 and Optigrating V4.2.2. It is seen that the optimum case that gave highest cladding power to core power ratio is the case of etching for 10 min, which can be used for detection applications. This ratio greatly affects the sensitivity of the system.

Abstract
Optical fibers are a key inventive discovery that contributed to the digital revolution, although cost becomes a major factor for long-distance communication. Whereas passive optical networks (PONs) offer reduced costs and cater to multiple users; hence, they are becoming more common in LANs, densely inhabited areas, and backbone networks. Numerous experiments on PON systems have been authored in the last couple of years, with results expressed in terms of BER, eye openings, quality of received bits factor, signal-to-noise ratio (SNR), and burst blocking, which demands a vast review of PONs based on these parameters. So, a comprehensive review of PONs is extensively researched to identify the methods’ limitations. Along with long-reach(LR)-PON systems, power conservation in PONs and burst contention are also addressed. To demonstrate the performance of PON architectures, the findings are provided in terms of delay, energy efficiency, and operations intensity.
Distortion managed directly modulated on-off keying signal transmission for 10 Gbps visible light communications using electrical filtration
Authors: Sudhakar Muppidi Venkata , Rajini Gaddam Kesava Reddy 
Published: July 2023

Abstract
In this research, a communication system that uses visible light as a carrier and is designed for high-throughput interior applications. In order to lower the overall system cost, this work uses intensity modulation at the transmitter and direct detection with electrical filtering at the receiver. Various low-pass filtration techniques (Gaussian, Butterworth, Bessel, and Chebyshev) have been proposed in his paper to mitigate the effect of channel distortion in visible light communication (VLC) systems. The achieved transmission range is up to 3 m in addition to the supported data rate of 10 Gbps with a bit error rate of less than 10−9. Simulations are carried out using optisystem software that includes PRBS OOK optical signal generation at LED output in the transmitter, VLC channel, and APD with LPF in the receiver.

Published: July 2023

Abstract

Objectives
To highlight important clinical aspects of Persistent Müllerian duct syndrome (PMDS). PMDS belongs to the group of differences of sex development. It is attributed to mutations in genes encoding for the anti-Müllerian hormone or its type II receptor (AMHR2) and inherited via an autosomal recessive transmission.

Case presentation
An 18-day-old male infant with known bilateral cryptorchidism, presented with left-sided obstructed inguinal hernia. The diagnosis of PMDS was considered during inguinal exploration as both testes together with uterus and fallopian tubes were recognized in the hernial sac. Histology confirmed the presence of Müllerian-derived tissues. Genetic testing revealed two different mutations of the AMHR2 gene, both with autosomal recessive transmission: a frequently encountered deletion of 27 pairs bases on exon 10 of this 11 exon gene and a novel deletion of 2 pairs bases on exon 6.

Conclusions
This case is notable being the rarest type of PMDS, that of transverse testicular ectopia and associated with a novel AMHR2 gene mutation.
Navigating liminal spaces together: a qualitative metasynthesis of youth and parent experiences of healthcare transition

Published: July 2023

Abstract
Transition from pediatric to adult care for adolescents and young adults (AYAs) with chronic illness affects the entire family. However, little research has compared AYA and parent experiences of transition. Using Sandelowski and Barroso’s method, the aim of this metasynthesis was to summarize findings of qualitative studies focusing on the transition experiences of AYAs and their parents across different chronic physical illnesses. PubMed, EMBASE and CINAHL were searched followed by forward and backward citation searching. Two authors completed a two-step screening process. Quality was appraised using Guba’s criteria for qualitative rigor. Study characteristics and second order constructs were extracted by two authors and an iterative codebook guided coding and data synthesis. Of 1,644 records identified, 63 studies met inclusion criteria and reflect data from 1,106 AYAs and 397 parents across 18 diagnoses. Three themes were synthesized: transition is dynamic and experienced differently (differing perceptions of role change and growth during emerging adulthood), need for a supported and gradual transition (transition preparation and the factors which influence it) and liminal space (feeling stuck between pediatric and adult care). While AYAs and parents experience some aspects of transition differently, themes were similar across chronic illnesses which supports the development of disease agnostic transition preparation interventions. Transition preparation should support shifting family roles and responsibilities and offer interventions which align with AYA and family preferences.
Fine-tuning biexcitons-plasmon coherent states in a single nanocavity

Published: July 2023

Abstract
A tunable plexcitonic material that sustains multimode hybridization is highly desirable, which is vital for advanced quantum devices. However, the research about regulations of biexcitons-plasmon coherent states has rarely been reported. Here we apply single-nanoparticle scattering spectroscopy correlative with SEM imaging to identify biexcitons-plasmon interaction in a metal-semiconductor hybrid structure composed of a single Au@Ag nanoparticle, J-aggregates molecules and tungsten disulfide (WS2) monolayer. The mode competition within the localized plasmonic hotspots (∼240 nm3) is revealed by continuously regulating the J-aggregates spacer. Two distinct anticrossings are observed at both excitons resonances, and large double Rabi splittings (137 meV and 124 meV) are obtained successfully. We establish experimentally that J-aggregates and WS2 monolayer are responsible for the middle polariton states, while plasmon rarely contributes. Further calculations show that plasmonic nanocavity enables coherent energy exchange with different excitons by providing a highly enhanced localized E-field. In addition, we find that the multimode coupling strengths can be efficiently tuned by changing the cavity morphology and environment temperature, where the tuning spectral accuracy can reach up to 1 nm. Our findings uncover the distinctive properties of biexcitons-plasmon polaritons, suggest an easily obtainable multiqubit states platform, and open up a new way to construct nanoscale photonic devices.

Published: July 2023

Abstract

Objectives
Peritoneal metastases (PM) and liver metastases (LM) are present simultaneously in up to 2 % of patients at the time of their colorectal cancer (CRC) diagnosis. Curatively intended treatment includes cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) combined with LM resection. A less invasive treatment for LM is ablation. We aimed to estimate overall survival (OS), disease-free survival (DFS) and postoperative data in patients managed simultaneously with CRS, HIPEC and radiofrequency ablation (RFA) as first choice.

Methods
This was a retrospective national cohort study. All patients were treated at Aarhus University Hospital; the only CRS+HIPEC centre in Denmark. We included CRC patients managed with curative intent for simultaneously diagnosed PM and LM in the period January 2016 – December 2021. LM was treated with RFA as first choice, if possible. Survival was calculated by the Kaplan-Meier method.

Results
A total of 25 patients were included, the median age was 60 years (range 43–75 years) and 15 (60 %) were females. The median peritoneal cancer index was 7 (range 0–12), the median number of LM was 1 (range 1–3). Ablation was performed as the only treatment for LM in 18 (72 %) patients. After a median follow-up time of 17.1 months (range 4–36 months), the median OS was 28.6 months (95 % confidence interval (Cl) 15.8;36.1), 1-year OS was 84.0 % (95 % Cl 62.8;93.7). Median DFS was 6.1 months (95 % Cl 4.0;10.3). Median LOS was ten days (range 5–26 days). Both 30-day and 90-day mortality were 0 %.

Conclusions
The selected treatment modality (RFA) for CRC patients with both LM and PM was safe. However, DFS was low. Further research is warranted to investigate if RFA is as effective as LM resection.

Abstract
Functional foods, drug delivery systems, and cosmetics are the main areas of application for multiphase systems, where the use of naturally derived compounds is preferred. Hence, this study aimed to assess the possibility of using natural surfactants and saponin-rich extracts to produce emulsions containing antibacterial and antioxidant cinnamon and clove essential oils (EOs). The analyses of nanoparticles using dynamic light scattering showed that the addition of plant extracts to solutions allows one to obtain stable emulsions and decreased zeta potential (< −40 mV) and droplet size (<200 nm). In all investigated emulsions, the increase of antioxidative properties was observed when both EOs and plant extracts were used. The emulsion with clove oil stabilized with Quillaja saponaria bark saponins has the highest combined antioxidative properties (3.55 ± 0.01 μg gallic acid equivalent per g). Additionally, a stronger antibacterial action against Pseudomonas bacteria was observed for clove oil with Quillaja saponaria and cinnamon oil with Glycyrrhiza glabra. In addition, plant extracts did not affect significantly the other properties of the oil emulsions, e.g. wettability, colour, and refractive index. All results show that the proposed emulsions can be helpful in the preparation of multifunctional emulsions, where the co-action of saponins and EOs is especially beneficial.

The gender of language contact
Authors: Narayanan Sandhya Krittika 
Published: July 2023

This article considers how language contact is gendered through an analysis of how inter-Indigenous Quechua–Aymara boundary maintenance practices and ideologies are feminised in the Peruvian altiplano. The analysis focuses on the semiotic regimentation of Indigenous ethnolinguistic boundaries, concentrating on the role of four Indigenous female figures: the Indigenous wife; the Indigenous female market vendor; the reimagined mythic Indigenous founding mother; and the Indigenous beauty pageant contestant. An ethnographically grounded, scalar analysis of Quechua–Aymara contact in the region shows how each of the female figures is ideologically linked to a specific aspect of inter-Indigenous language contact and boundary maintenance. Furthermore, the discussion shows the interconnectedness of these female figures and their associated ideologised practices and discourses, which lead to the feminisation of inter-Indigenous language contact in the region.

Authors: Anguiano-Constante Marco Antonio , Dean Ellen , Munguía-Lino Guadalupe , Sánchez-Carbajal Daniel , Ruiz-Sánchez Eduardo , Rodríguez Aarón 
Published: July 2023

Background: Lycianthes moziniana (Capsiceae, Solanaceae) is an endemic and widespread species in Mexico. Morphological and molecular evidence suggested three varieties (L. moziniana var. margaretiana, L. moziniana var. moziniana and L. moziniana var. oaxacana).
Hypotheses: Lycianthes moziniana is integrated by differentiated lineages corresponding to the three varieties identified.
Studied species: Lycianthes moziniana (Dunal) Bitter.
Study sites and dates: Mexico from 2017 to 2021.
Methods: We measured 11 morphological characters based on 207 herbarium specimens. Discriminant Canonical Analysis (DCA), Mahalanobis Square Distance (MD) and Canonical Classificatory Analysis (CCA) were used to uncover the differences among varieties. For geographic and climatic preferences and divergence, we used 288 records and four climatic layers.
Results: Two canonical functions explained 100 % of the morphological variation and seven characters had the highest discriminatory power. In addition, MD was statistically significant. Meanwhile, the CCA recovered three groups at 77 %. The morphological evidence demonstrated the distinctiveness of L. moziniana var. moziniana. In contrast, L. moziniana var. margaretiana and L. moziniana var. oaxacana were morphologically similar. The identity test showed significant differences among Ecological Niche Models (ENMs). The evidence indicates geographic and climatic isolation among the varieties. Lycianthes moziniana var. moziniana is widespread and has intermediate overlap with the other two varieties. Lycianthes moziniana var. margaretiana and L. moziniana var. oaxacana were isolated in different biogeographical provinces and showed the lowest overlap.
Conclusions: Morphological and geographic data indicates incipient speciation is occurring.
Spectral amplification in a sediment-filled Valley exhibiting clear basin-edge-induced waves
Authors: Field Edward H. 
Published: July 2023

Abstract
Various site-response estimates are presented for a linear array deployed in the Coachella Valley, California, during the 1992 Landers/Big Bear aftershock sequence. This systematic comparison is unique in that the response of the site is clearly dominated by basin-edge-induced waves. Average sediment to bedrock spectral ratios for long S-wave windows, which include the basin-edge-induced waves, exhibit amplification factors as high as ∼ 18, below 7 Hz. The deep basin structure, which gives rise to the obvious multi-dimensional effects, produces a fundamental resonant peak that shifts between basin sites (from 0.23 to 0.48 Hz) as the depth to bedrock changes. Above 0.6 Hz, where the largest amplifications occur, the response is remarkably similar between sites and appears to be dominated by a near-surface layer that is relatively uniform across the valley. The apparent fundamental resonant frequency of this layer is between 0.8 and 1 Hz. Sediment to bedrock spectral ratios computed using shorter windows that exclude the basin-edge-induced waves imply that the multi-dimensional effects are significant only below ∼ 4 Hz, where they increase amplifications by an approximate factor of 2. Spectral ratios computed using coda windows, taken at twice the S-wave travel time, exhibit amplifications that are an average factor of 1.7 greater, between 1 and 4 Hz, than those of the S-wave estimates. This discrepancy does not improve by taking coda windows later at four times the S-wave travel time. Horizontal- to vertical-component S-wave spectral ratios do not agree with the sediment to bedrock ratios. However, they do exhibit a clear peak at the fundamental resonant frequency of the deep basin structure. Sediment to bedrock spectral ratios of ambient seismic noise are also inconsistent with the S-wave estimates. However, horizontal to vertical noise ratios exhibit clear peaks near the fundamental resonant frequencies of both the deep basin structure (below 0.6 Hz) and the suspected near-surface layer (between 0.8 and 1 Hz). Therefore, ambient-noise data appear to provide valuable constraints on the basin structure. Ongoing efforts involve multi-dimensional modeling of the observed basin-edge-induced phases and resonant frequencies.
Validation of a procedure for calculating broadband strong-motion time histories with empirical Green's functions
Authors: Jarpe S. P. , Kasameyer P. W. 
Published: July 2023

Abstract
We quantitatively evaluate the validity of an approach to calculating strong ground motion time histories that involves the kinematic modeling of earthquake rupture by using recorded empirical Green's functions to constrain the propagation path and site contribution in the period range 0.05 to 2.0 sec, leaving only the contribution of the source to be specified. In addition, we use numerical Green's functions for long periods (&gt; 10 sec) where the average crustal structure is assumed to be well known. In the intermediate band (2 to 10 sec) where site and path effects are still important but empirical Green's functions have small signal-to-noise ratios, we use an arbitrary smoothing method to connect the numerical and empirical Green's function synthetics. The evaluation presented here consists of comparing actual recordings of the Loma Prieta earthquake at 26 sites to syntheses from a simple source model similar to what is thought to have occurred during the Loma Prieta earthquake. We show that the standard error between observed and predicted response spectra is less than or equal to errors from other methods for periods between 0.05 and 0.4 sec and is significantly less than regression methods based on pre-Loma Prieta empirical strong-motion data at periods between 0.5 and 5.0 sec.
The strong ground motion prediction methodology that we are validating provides an accurate, defendable means to characterize site and path effects and, therefore, allows the uncertainties in the predicted hazard to be due to unresolved issues about the earthquake source such as the geological constraints of a particular fault and details about the physics of earthquakes. This methodology produces accurate and realistic acceleration and displacement time histories, which are becoming increasingly important for modeling the nonlinear response of large, distributed structures and soft soils. The implication for strong ground motion prediction is that a range of representations of an earthquake source based on physically realistic parameters can be used to generate a suite of possible time histories that represent the range of ground motion for that specific site and earthquake. In addition, in the future, as more information about a particular fault and earthquakes in general becomes available, the uncertainty in ground-motion prediction should decrease.
Self-healing slip pulses in dynamic rupture models due to velocity-dependent strength
Authors: Beeler N. M. , Tullis T. E. 
Published: July 2023

Abstract
Seismological observations of short slip duration on faults (short rise time on seismograms) during earthquakes are not consistent with conventional crack models of dynamic rupture and fault slip. In these models, the leading edge of rupture stops only when a strong region is encountered, and slip at an interior point ceases only when waves from the stopped edge of slip propagate back to that point. In contrast, some seismological evidence suggests that the duration of slip is too short for waves to propagate from the nearest edge of the ruptured surface, perhaps even if the distance used is an asperity size instead of the entire rupture dimension. What controls slip duration, if not dimensions of the fault or of asperities?
In this study, dynamic earthquake rupture and slip are represented by a propagating shear crack. For all propagating shear cracks, slip velocity is highest near the rupture front, and at a small distance behind the rupture front, the slip velocity decreases. As pointed out by Heaton (1990), if the crack obeys a negative slip-rate-dependent strength relation, the lower slip velocity behind the rupture front will lead to strengthening that further reduces the velocity, and under certain circumstances, healing of slip can occur. The boundary element method of Hamano (1974) is used in a program adapted from Andrews (1985) for numerical simulations of mode II rupture with two different velocity-dependent strength functions. For the first function, after a slip-weakening displacement, the crack follows an exponential velocity-weakening relation. The characteristic velocity V0 of the exponential determines the magnitude of the velocity-dependence at dynamic velocities. The velocity-dependence at high velocity is essentially zero when V0 is small and the resulting slip velocity distribution is similar to slip weakening. If V0 is larger, rupture propagation initially resembles slip-weakening, but spontaneous healing occurs behind the rupture front. The rise time and rupture propagation velocity depend on the choice of constitutive parameters. The second strength function is a natural log velocity-dependent form similar to constitutive laws that fit experimental rock friction data at lower velocities. Slip pulses also arise with this function. For a reasonable choice of constitutive parameters, slip pulses with this function do not propagate at speeds greater than the Raleighwave velocity. The calculated slip pulses are similar in many aspects to seismic observations of short rise time. In all cases of self-healing slip pulses, the residual stress increases with distance behind the trailing edge of the pulse so that the final stress drop is much less than the dynamic stress drop, in agreement with the model of Brune (1976) and some recent seismological observations of rupture.
