Authors: Liang Rong , Zhou Xiaojun , Xu Huangrong , Wu Dengshan , Li Chenxi , Yu Weixing 
Published: February 2024

For gravitational wave detection, the telescope is required to have an ultra-low wavefront error and ultra-high signal-to-noise ratio, where the power of the stray light should be controlled on the order of less than 10−10. In this work, we propose an alternative stray light suppression method for the optical design of an off-axis telescope with four mirrors by carefully considering the optimal optical paths. The method includes three steps. First, in the period of the optical design, the stray light caused by the tertiary mirror and the quaternary mirror is suppressed by increasing the angle formed by the optical axes of the tertiary mirror and the quaternary mirror and reducing the radius of curvature of the quaternary mirror as much as possible to make sure the optical system provides a beam quality with a wavefront error less than λ/80. Next, the stray light could satisfy the requirement of the order of 10−10 when the level of roughness reaches 0.2 nm, and the pollution of mirrors is controlled at the level of CL100. Finally, traditional stray light suppression methods should also be applied to mechanics, including the use of the optical barrier, baffle tube, and black paint. It can be seen that the field stop can efficiently reduce stray light caused by the secondary mirror by more than 55% in the full field of view. The baffle tube mounted on the position of the exit pupil can reduce the overall stray light energy by 5%, and the difference between the ideal absorber (absorption coefficient is 100%) and the actual black paint (absorption coefficient is 90%) is 3.2%. These simulation results are confirmed by the Monte Carlo method for a stray light analysis. Based on the above results, one can conclude that the geometry structure of the optical design, the quality of mirrors, and the light barrier can greatly improve the stray light suppression ability of the optical system, which is vital when developing a gravitational wave telescope with ultra-low stray light energy.

Published: February 2024

Small-sized, highly sensitive dynamic pressure sensors are crucial in the field of turbomachinery application. In this paper, a fiber-tip structure dynamic pressure sensor utilizing a small piece of glass tube as the air cavity and PDMS material as the diaphragm was fabricated. It has the advantage of being small in size with the diameter of 125 µm while having high sensitivity of 26.26 pm/kPa. The fabrication process was described in detail, which is simple and cost-effective. The sensor characteristics were studied theoretically and experimentally. Quasi-square pressure signal of different frequencies generated by the siren disk were measured by the sensor and compared with that obtained from the commercial piezoresistive pressure sensor to verify the accuracy of the proposed sensor. The R2 of the four pairs of pressure waveforms were 0.94, 0.81, 0.93, and 0.96, respectively. Stability testing of the sensor was also performed, showing that the sensor can work reliably under dynamic pressure environment.
SBS mitigation by sinusoidal phase modulation of a 1572  nm all-fiber amplifier for lidar CO2 sensing
Authors: Pichon Pierre , Le Gouët Julien , Lombard Laurent 
Published: February 2024

Lidar CO2 sensing can be performed by
1572 nm pulsed laser sources. This work presents the
development of a fiber amplifier at this wavelength emitting
1 µs FWHM Gaussian pulses at a repetition rate of
7.5 kHz. We obtain the mitigation of stimulated Brillouin
scattering (SBS) by shaping the seed laser spectrum into a frequency
comb with sinusoidal phase modulation. This frequency comb is
compatible with a coherent dual-comb spectroscopy (DCS) method for a
targeted lidar CO2 sensing application. The effect of
the harmonics spacing and relative intensity on the SBS threshold is
studied. Laser pulses are amplified up to 182 µJ (182 W
peak power) from a single-mode erbium (Er) and ytterbium (Yb) co-doped
fiber. Those results hold promise for seeding large mode area Er-Yb
co-doped fiber power amplifiers.
Design method for engineering the initial structure of a spectrometer
Authors: Yang Zhaoqing , Xue Meng , Guo Hanming 
Published: February 2024

A well-considered initial structure plays a key role in the design of an exceptional spectrometer. Previously, the design method for the optical initial structure (MOIS) that has only focused on the optical properties based on simple imaging formulas and coma-free conditions has been extensively researched. However, as the shape and size of any optical component are not considered for the MOIS, the optical parameters before and after optimization are very different, which results in a loss of reference value of the initial structure. In order to address the aforementioned issues, a more efficient design method for engineering initial structure (MEIS) of the spectrometer is proposed, where not only the above optical properties are considered but also the relative position and size of any optical component in order to avoid the interference between the optical components. For the MEIS, three important anti-interference conditions between components are deduced through ray tracing, and the relevant imaging formulas are derived by geometric optics, which leads to the rapid calculation of component parameters and the acquisition of an initial structure satisfying the corresponding design requirements by setting reasonable spacing margins. To verify the validity of the MEIS, a wide-band high-resolution spectrometer system with a large CCD Toucan 216 is designed within a wavelength range of 700–1000 nm and a resolution of 0.5 nm. Compared with the MOIS, the positions of each component in the MEIS are more rationalized, which significantly eliminates the complex optimization processes. For the MEIS, changes only in the position of the image plane occur with minimal variations in the axial and vertical wheelbase (less than 0.5 mm) as well as the deflection angle (only 0.5°), with favorable evaluation indices. The MEIS has an important reference value for the rapid and efficient design of excellent spectrometers.
Photonic comb: a stabilized single-mode fiber etalon for wavelength calibration
Authors: Betters Christopher H. , Leon-Saval Sergio G. , Bland-Hawthorn Joss 
Published: February 2024

We present a low-cost alternative to more complex laser metrology systems that uses a single-mode fiber Fabry–Perot etalon to generate an emission spectrum of evenly spaced lines with similar intensities, ideal for calibrating spectrographs (both in terms of wavelength and image quality). The system uses the hyperfine transition lines of 87Rb near 780.24 nm as an absolute reference. By controlling the cavity dimensions by small changes in temperature, we can tune and thus stabilize the transmission spectrum. A 20 Hz PID loop controls the etalon temperature and locks it to the 87Rb transitions. Through this method, we achieve a centroid error/precision of <1m/s (2.6 fm or 1.3 MHz) for 1 s integrations and 1 cm/s (0.026 fm or 13 kHz) for 30 min integrations of the reference line. We also show that a solution can be found to mathematically describe the spectrum. With the correct calibration and environmental controls in place, we show that this setup has the potential to be competitive with the best existing methods based on expensive and cumbersome laser combs.
Psychometric properties of the Arabic version of the perceived prosthodontic treatment need scale: Exploratory and confirmatory factor analyses
Authors: Sharka Rayan 
Published: February 2024

BackgroundIt is crucial to take into account the concerns of dental patients about their prosthodontic needs when planning the course of treatment. However, there is a dearth of research that examines these needs among adult dental patients.ObjectivesThis study aims to translate and validate the perceived prosthodontic treatment need scale (PPTN) in Arabic.MethodsThe 17-item PPTN scale was translated from English into Arabic and completed by 206 patients seeking prosthodontic treatment in a dental hospital in Saudi Arabia. Data collection was carried out in September and October 2023. Exploratory factor analysis (EFA) was used to ascertain the underlying factor structure; a unidimensional scale was hypothesised and tested using confirmatory factor analysis (CFA), including several multiple model fit indices. The assessment of reliability was conducted using Cronbach’s alpha. The convergent and discriminant validity of the final scale were examined.ResultsEFA produced an 11-item scale distributed into three factors that explain 65.43% of the total variance with eigenvalues > 1. All items showed acceptable reliability, ranging from 0.65 to 0.84. The first factor pertained to social issues, while the second item was concerning dental appearance. Lastly, the third factor included functional difficulties associated with tooth loss or dental problems. The results of the CFA demonstrate a satisfactory level of model fit, with the standardised factor loadings ranging from 0.51 to 0.89. Convergent and discriminant validity of the model factors were established.ConclusionThe translated questionnaire was deemed legitimate and would be useful in comprehending patients’ perceived treatment requirements, hence contributing to the advancement of prosthodontic research and practical implementation.

Published: February 2024

Background: The trend of diabetes cases has shifted to younger ages, starting at the age of 15 years old, due to unhealthy lifestyles. Researchers have discovered that health students also tend to have a poor lifestyle. Students are associated with emotional activity and busyness, but no research has examined the relationship between these conditions and diabetes prevention behavior. Purpose: This study examined determinant factors affecting diabetes prevention behavior in college students with diabetes mellitus risk.Methods: This study used a cross-sectional design, utilizing random sampling to gather data from 209 college students with diabetes risk. The instruments used in this study included adaptations of the Diabetes Prevention Behavior questionnaire, the modified Diabetes Management Time Questionnaire (DMTQ), the Perceived Behavioral Control, and the Trait Emotional Intelligence Questionnaire. Data analysis encompassed One-way ANOVA, Mann-Whitney, Kruskal-Wallis, Spearman’s rank, and multiple linear regression.Results: The study found a significant relationship between diabetes management time (p=0.001) and emotional intelligence (p=0.000) with diabetes prevention behavior. Emotional intelligence emerged as the dominant influencing factor (B=0.332). Conversely, no significant relationships were observed between perceived behavior control (p=0.223), class (p=0.734), sex (p=0.231), study major (p=0.263), age (p=0.064), and diabetes mellitus risk (p=0.664) with diabetes prevention behavior.Conclusion: This study revealed a significant relationship between diabetes management time, emotional intelligence, and diabetes prevention behavior. Emotional intelligence emerged as the key factor affecting diabetes prevention behavior, highlighting the need for focused interventions to enhance emotional intelligence and improve diabetes management among college students.

OBJECTIVES
To measure associations between residential moves because of unaffordable housing costs and disruptions in access to the Supplemental Nutrition Assistance Program; the Special Supplemental Nutrition Program for Women, Infants, and Children; and Medicaid in a health care-based sample of families with young children.

METHODS
We used cross-sectional survey data on social safety net-eligible caregivers and children recruited into the Children’s HealthWatch study from emergency departments and primary care clinics in Baltimore and Philadelphia (2011–2019). Children’s HealthWatch measured residential moves (cost-driven and noncost-driven) in the past year and disruptions in safety net access. We used logistic regression to estimate associations between each type of move and disrupted access to social safety nets.

RESULTS
Across 9344 children, cost-driven residential moves were associated with higher odds of disrupted access to at least 1 safety net program (Supplemental Nutrition Assistance Program; the Special Supplemental Nutrition Program for Women, Infants, and Children; or Medicaid; adjusted odds ratio 1.44; 95% confidence interval 1.16–1.80), as well as higher odds of disruption to each program separately. Noncost-driven moves were also associated with disruptions to at least 1 safety net program, but less strongly so (adjusted odds ratio 1.14; confidence interval 1.01–1.29; P value for comparison with cost-driven = .045).

CONCLUSIONS
Residential moves, particularly cost-driven moves, are associated with social safety net benefit disruptions. The association between these events suggests a need for action to ensure consistent safety net access among children facing cost-driven moves and vice versa (ie, access to housing supports for children with disrupted safety net access).

In the rapidly evolving healthcare landscape, integrative care delivery stands at the forefront of pioneering change, particularly in prenatal care. This comprehensive narrative review delves into the development of innovative models for integrative prenatal care, such as telemedicine-integrated home monitoring systems, mental health apps, virtual reality, artificial intelligence-powered predictive analytics and blockchain for secure health data management, proposing a paradigm shift from traditional methodologies to a more holistic, technology-empowered approach. We explore the interplay between cutting-edge technological advancements and interdisciplinary collaboration in crafting a care model that is patient-centric and adaptable to diverse healthcare settings. Moreover, key areas where integration can be significantly enhanced such as telemedicine, patient education, and continuous monitoring were identified, emphasizing the importance of synergy between medical expertise, patient engagement, and technology, aiming to improve outcomes for both mother and child and argue that the future of prenatal care lies in embracing innovation, flexibility, and inclusivity, setting a new standard in healthcare delivery. This work offers practical insights for healthcare professionals and policymakers aspiring to transform prenatal care into a more effective, accessible, and patient-friendly experience.
The Contribution of Systemic Modelling and of Early Maladaptive Schema in Psychiatric Expertise
Authors: Pavlovici Bogdan 
Published: February 2024

There are limits in international classifications like DSM 5, CIM 10, which are periodically updated in order to adapt to the constantly changing psychiatric field.
Furthermore, the DSM 5 does not allow the mention of a personality disorder before 18 years of age.
The modelling proposed by Jeffrey Young-American psychologist-, that of « early maladaptive schema » provide a way out of stagnation by bringing vulnerabilities to the forefront. These may, from an expertal viewpoint, explain some psychological processes that may lead to delinquent behaviours or become fertile ground for agression and development of psychological trauma.
The modelling proposed by various systemic theory scientists allows for a more in depth explanation of progressive build-up of a pathology through repeat dysfunctional systemic interactions.
This contribution is very useful in judicial but also familial expertise.
I will illustrate my remarks through two clinical studies.
Some Aspects Regarding the Psychology of the Surgical Patient
Authors: Voicu Dragos , Popazu Constantin , Stan Dorina , Burlea Stefan Lucian 
Published: February 2024

The need for a medical consultation always generates an unpleasant sensation, which becomes more accentuated, when the doctor is a surgeon. The surgeon is next to the dentist, gynecologist and psychiatrist, the doctor to whom the patient turns with the greatest fear. The operative indication and the discussion of therapeutic perspectives can trigger a psycho-emotional imbalance, leading to tomophobia. In fact, it is a complex psychological reaction, including odynophobia (fear of pain), dysmorphophobia (fear of postoperative bodily sequelae), hypnophobia (fear of anesthetic sleep, from which one could not wake up), trypanophobia (fear of injections, needles, scalpel), pantophobia (fear of everything that happens around, in this case, in the hospital environment) and above all, thanatophobia (fear of death). Therefore, it can be stated that the surgical intervention is a test of the psycho-affective capacity.
The paper presents the authors' experience in 20 years (2002-2021), related to the psychological management of surgical patients, subjected to medium or large-scale surgical interventions (75% performed in emergency mode), in 958 patients.
Mental stress can have consequences, both on the reactivity of the surgical patient and on his postoperative evolution. In the time crunch and in the absence of a psychologist, available to offer specific advice on medical objectives, the management of perioperative anxiety rests with the surgeon and the nursing staff.

Introduction: Psoriasis is a chronic condition with a strong impact on the daily life of patients, especially on relationship life. This paper aims to clarify the impact of depression on the quality of life of patients with moderate psoriasis. Methods: A cross-sectional study was conducted on 16 participants with psoriasis from April to May 2023. Patients with psoriasis vulgaris completed self-administered questionnaires which include demographic characteristics, Hamilton Depression Rating Scale (HAM-D) and Dermatological Life Quality Index (DLQI). Data were collected both physically, during periodic checks and online by email. Only 16 patients met the eligibility criteria for study entry. All patients included in the study had moderate psoriasis vulgaris. Exclusion criteria for participation in the study was: current use of psychotropic medications. severe comorbidities or chronic medical conditions and visual, auditory, linguistic, or cognitive impairments. Results: After completed the Hamilton Depression Rating Scale (HAM-D) half of them 8 (50%) had a score lower than 8 (minimal depression) and the other half 8 (50%) between 8-16 (mild depression). 14 (87.5%) of the participants had a DLQI score of more than 10, indicating severe impairment in their quality of life. The results obtained showed a positive correlation between Dermatological Life Quality Index (DLQI) andHamilton Depression Rating Scale (HAM-D). Conclusions: Depressive manifestations significantly influence the quality of life of psoriasis patients analyzed. A multidisciplinary approach in treating the patient with psoriasis is indispensable because it is not only necessary to manage a disease or a "case", but also to manage a patient.

Published: February 2024

Introduction: Lymphatic filariasis, a neglected tropical disease (NTD), is a parasitic disease caused by microscopic worms that live only in the human lymphatic system. Mosquitoes, as vectors of lymphatic filariasis, play an important role in the prevention of this disease. The aim of this study was to identify agent, vector, and physical environment risk factors for filariasis in developing countries through a literature review. Discussion: This study was conducted using the narrative literature review method. The main sources for this study were articles from Google Scholar, Research Gate, PubMed, Springer, Scopus, and DOAJ databases. The criteria for articles were published between 2012 and 2022, observational studies including cross-sectional, case-control, and cohort designs, open access, and articles were organized according to STROBE guidelines. This study showed that from a total of 100 articles found, 14 articles met the predetermined criteria. Wuchereria bancrofti is the most common agent of filariasis. Culex and Anopheles are the vectors. The presence of bed nets and sewerage conditions were physical environment risk factors for filariasis in developing countries. Conclusion: Prevention of filariasis can be achieved by using mosquito nets or insect repellent when sleeping at night. In addition, open drains should be cleaned regularly to prevent them from becoming breeding sites for mosquitoes as vectors.
