Published: July 2023

Wide spectrum and miniaturization are the main challenges in the imaging spectrometer design. In this paper, we propose an ultra-compact dual band imaging spectrometer (CDBIS) with cemented freeform prisms, which works at both the visible-near-infrared (VNIR) from 400 nm to 1000 nm and the shortwave-infrared (SWIR) from 1000 nm to 1700 nm. The imaging spectrometer is only composed of three cemented prisms, a primary prism and two triangular prisms. And a freeform surface characterized by the Zernike polynomial is introduced in each prism. The CDBIS is dispersed by a diffraction grating, which is designed on the second surface of the primary prism. Based on vector aberration theory (VAT), the relationship among the astigmatism generated by the introduced freeform surfaces, the wavelength, and the field of view is studied. Accordingly, a wideband is realized by introducing the freeform surfaces after the diffraction grating. Furthermore, through optimizing the coefficients of Zernike polynomial terms, residual astigmatism at different wavelengths is well balanced. An imaging spectrometer with a volume of only 100cm3 is obtained, with a spectral resolution of 1.45 nm at VNIR and 2.40 nm at SWIR, respectively. It has a huge potential for broadband space exploration.

Authors: Yoo S. J. Ben 
Published: July 2023

The rapid increases in data traffic coupled with user preferences are
driving the data center and computing system service providers to
offer energy-efficient, intelligent, flexible, cost-effective,
high-capacity, and low-latency data services without added complexity
to the users. Disaggregated heterogeneous reconfigurable computing
systems realized by photonic switching and interconnects can enhance
throughput and energy efficiency for artificial intelligence/machine
learning (AI/ML) workloads, especially when aided by the
AI/ML-enhanced control plane. Photonic switching and new optical
networking architectures are expected to solve many of these
challenging problems. This paper discusses new trends in photonic
switching and optical network architectures for future data centers
and computing systems summarized as follows: (1) flat
reconfigurable disaggregated computing enabled by high-radix photonic
switching and interconnects in data centers; (2) chiplet-based
computing architectures empowered by embedded photonics toward
heterogeneous reconfigurable computing; (3) nanosecond-scale
photonic switching in data centers and computing systems;
(4) AI/ML in self-driving, application-aware, and
situation-aware data centers; (5) the emergence of flexible
networking for cloud computing, edge computing, and split computing,
as well as flexible networking for 5G/6G RF-optical networks; and
(6) the deployment of embedded co-designed silicon photonics
being considered for future data centers.

Background
Schistosomiasis and hookworm infection remain public health problems in large parts of sub-Saharan Africa. The epidemiology of schistosomiasis and hookworm was studied in seasonal transmission settings in the northern part of Côte d’Ivoire.

Methodology
In August 2018, a cross-sectional study was conducted. Urine and stool samples were collected from 742 individuals aged 6–96 years in 16 localities from four departments in northern Côte d’Ivoire. Urine samples were examined by a filtration method for quantification of Schistosoma haematobium eggs. Stool samples were subjected to duplicate Kato-Katz thick smears and eggs of Schistosoma mansoni and soil-transmitted helminths (STHs) were counted. Additionally, a questionnaire was administered to determine demographic characteristics and to identify risk factors of schistosomiasis and STHs. Malacologic surveys were carried out at water points that are contacted by humans and animals.

Principal findings
The prevalence of schistosomiasis was very low. Only two cases of S. mansoni were found (0.3%, 95% confidence interval [CI]: 0.1–1.0%). The distribution of S. haematobium was focal, with cases found only in two departments; Ferkessédougou (5.4%, 95% CI: 2.5–9.9%) and Ouangolodougou (2.7%, 95% CI: 0.9–6.3%). Hookworm was the only STH species observed with a prevalence of 1.5% (95% CI: 0.8–2.8%). A higher risk of S. haematobium infection was observed in males compared to females, but the difference was not statistically significant (2.3% versus 1.3%, odds ratio [OR]: 1.5, 95% CI: 0.8–2.7). Participants aged 16–20 years showed the highest prevalence of S. haematobium. A total of 111 human- and animal-water contact points were identified at 47 water sources. Three potential intermediate host snails of schistosomes were collected; namely, Bulinus forskalii (n = 761), Bulinus truncatus (n = 205), and Biomphalaria pfeifferi (n = 1). Yet, only one specimen of Bu. truncatus was found to be shedding schistosome cercariae.

Conclusions/Significance
This study confirms very low transmission of schistosomiasis and hookworm in northern Côte d’Ivoire. The establishment and rigorous implementation of integrated surveillance-response systems could lead to the elimination of schistosomiasis and hookworm in this part of Côte d’Ivoire.

ObjectiveThis study aimed to translate the DN4 questionnaire into Nepalese version and assess its psychometric properties: diagnostic accuracy, internal consistency, and test-retest reliability.MethodsAn observational study was conducted in a tertiary level teaching hospital of Kathmandu, Nepal. We included 166 patients with chronic pain visiting a pain clinic over a period of one year. The Nepalese version of the DN4 questionnaire was used for detecting signs and symptoms of neuropathic pain. The English version of the questionnaire was translated into Nepali in accordance with the standard guideline with the help of linguistic experts. The patients who met the inclusion criteria were examined and interviewed twice in an interval of two weeks. The association between the index test and the reference test was analyzed using Chi-square test. Diagnostic accuracy was assessed using sensitivity, specificity, Youden’s index, and positive and negative predictive values. We calculated internal consistency using Cronbach’s alpha (∝), and test-retest reliability using Cohen’s kappa and Intra-class correlation coefficient (ICC).ResultsThe study showed a significant association between the result of DN4 questionnaire and the gold standard (physician’s diagnosis) (p<0.001). The sensitivity and specificity values for the DN4 questionnaire were 75% and 95.3% respectively. Similarly, positive and negative predictive values were 93.8% and 80.4% respectively. Our study showed adequate internal consistency (∝ = 0.710) and a good test-retest reliability (kappa = 0.872, ICC = 0.877).ConclusionsThe Nepalese version of DN4 questionnaire is a valid and reliable tool for the identification of signs and symptoms of neuropathic pain. This can be used for screening neuropathic pain signs and symptoms in clinical as well as research settings.
Family health partners in regional network structures (NEST): A non-randomized controlled trial among parents of chronically ill and disabled children
Authors: Nickel Stefan , Helmreich Isabella , Broll Jan , Lüdecke Daniel 
Published: July 2023

Background
The overarching project goal is to evaluate the effectiveness of a cross-sectoral and cross-service provider offering professional support for families with chronically ill and disabled children: so-called Family Health Partners (in German: ‘Familien-Gesundheits-Partner’ or FGP). This needs-oriented service, which is anchored in regional networks, aims to provide ‘holistic’ support for families with children in need of care.

Methods
We are carrying out a non-randomized controlled trial with four points of measurement (t0-t3 in 18 months), beginning in January 2022. Both intervention and control group include 102 families. Primary outcome measure is the quality of life, secondary outcomes are resilience factors and associated measures as well as the access to care. Multilevel regression models will be used to analyze the longitudinal data.

Discussion
The strength of this study is that it looks at the health and resilience of all family members involved by examining how a FGP can influence the entire family system with regard to increasing quality of life, resilience and self-efficacy. The network structures of FGP also open up better to previously unknown regional supply offers. There are, however, a number of limitations (e.g. type of outcomes, sample size).

Trial registration
This study was first registered on the German Clinical Trials Register before enrolment of participants started (ID: DRKS00027465, 4 January 2022). In order to promote its dissemination, it was also retrospectively registered on ClinicalTrials.gov (ID: NCT05418205, 14 June 2022).

Introduction
Hepatitis B (HBV) prevalence remains high in Sub Saharan Africa and among some key populations such as those with continued exposure through sexual contact. We assessed the HBV status among potential participants who were screened for simulated HIV vaccine efficacy trials in Kenya and Uganda.

Methods
We conducted a cross sectional analysis of data collected from individuals who were screened in Kenya (Nairobi) and Uganda (Entebbe and Kampala). The studies followed hypothetical procedures of an HIV vaccine efficacy trial and aimed to enroll HIV negative key and vulnerable populations at elevated risk of HIV acquisition. HBV status was the main outcome categorized using Hepatitis B surface antigen (HBsAg) and total Hepatitis B core antibody (HBcAb). Baseline characteristics potentially associated with never being infected were analyzed using logistic regression.

Results
We screened 1,366 participants with mean age (SD) 28.7 (7.3) years. Overall, 46.6% were from Entebbe, 50.7% had secondary or higher level of education, 76.4% had informal high-risk jobs and 56.3% were male. Kampala had only female participants contributing 60.6% of females screened. Of the screened participants, 94.7% and 3.4% were negative and positive for HBsAg respectively. The prevalence on HBV infection was 3.9% among males and 2.8% among females while prevalence by site was: Entebbe (4.9%); Kampala (4.1%) and Nairobi (0.3%). The highest HBV prevalence was found among participants aged 25-29-years (5.2%), those with primary level education (4.5%), and those in informal low risk jobs (6.5%). Considering 1265 participants with complete data on HBsAg and HBcAb-Total, HBV status was never infected (67.9%), past infection (28.5%), chronic infection (3.2%) and acute infection (0.5%). Of 859 who were never infected, 685 (79.7%) were tested for anti-HBs titers of whom 60 (8.8%) had titers >10IU/L (immune due to vaccination). The odds of never being HBV infected were lower among older individuals 25–29 years (AOR 0.51; 95%CI 0.36–0.71) and ≥30 years (AOR 0.35; 95% CI 0.25–0.49). The odds were higher among participants with informal high-risk jobs from Kampala (AOR 2.21; 95% CI 1.41–3.47) and Nairobi (AOR 2.61; 95% CI 1.72–4.00) compared to those from Entebbe.

Conclusion
HBV prevalence and immunity due to vaccination were low among HIV negative individuals who are eligible for HIV vaccine trials and prevalence varies by age, education level and main occupation. Younger individuals and those recruited from existing cohorts/ clinics have a higher likelihood of having no prior HBV infection. HIV prevention intervention trials are a platform to identify individuals that need HBV vaccination.
Patient education interventions for adolescent and young adult kidney transplant recipients- a scoping review

Published: July 2023

BackgroundAdolescence and young adulthood are high risk periods for kidney transplant recipients. The reasons for this are complex; but are predominantly thought to be due to poor adherence to immunosuppressive medications. Patient education can help support young recipients to reduce their risk of behaviour-related transplant loss. The aim of this review was to understand what is known about education interventions targeted at adolescent and young adult kidney transplant recipients.MethodsSystematic scoping review methodology was utilised. Six online databases were searched for suitable articles. Articles were selected for full text review following title and abstract screening. Articles deemed eligible to be included in the review had data extracted, which were qualitatively analysed using thematic analysis. Findings were validated through a consultation exercise with both young recipients and healthcare professionals.Results29 studies were eligible for inclusion in the review. There was a high level of heterogeneity in the content, mode, design, and measurement of efficacy of interventions in the selected studies. Traditional face-to-face education and transition clinics were the most common educational interventions. Using technology to enhance patient education was also a major theme identified. Few studies reported using educational theory or involving patients in intervention design.DiscussionFour key research gaps were identified. 1.) Lack of educational theory in intervention design 2.) Lack of patient/ stakeholder involvement 3.) Identifying best way to measure efficacy 4.) identifying novel future research questions within already well established paediatric and educational frameworks. Addressing these gaps in future research will help inform best-practice in this vulnerable population.

Published: July 2023

Magnetite synthesis using petai (Parkia speciosa) peel extract using the sonochemical method (Fe3O4-PPE) has been successfully carried out. Fe3O4-PPE is applied as a catalyst in biodiesel production. This study aimed to determine the physical and chemical characteristics of Fe3O4-PPE and its ability as a reusable catalyst in biodiesel production using waste frying oil as the primary raw material. Characterization of Fe3O4-PPE was carried out using FTIR, XRD, and PSA instruments. Biodiesel was produced in 3 reaction cycles with the same Fe3O4-PPE catalyst. The results of the FTIR characterization showed that the Fe3O4-PPE catalyst had Fe-O bonds from Fe3O4 and -OH phenolic groups, -C-O, -C=C aromatic compounds derived from petai peel extract. The crystal size of the Fe3O4-PPE catalyst based on the results of calculations using Debye-Scherrer from the XRD chromatogram is 9.41 nm. The particle size of the Fe3O4-PPE catalyst based on analysis using PSA was divided into three groups, namely, 5.4 nm, 195 nm, and 2702.6 nm. Fe3O4-PPE was successfully used as a reusable catalyst for three cycles of biodiesel production using waste frying oil as raw material. The characteristics of Fe3O4-PPE before and after being used as a catalyst did not change. Based on GC-MS analysis, the fatty acid methyl ester (FAME) composition of biodiesel is palmitic acid and oleic acid.

Published: July 2023

Abstract
We introduce the notion of a wall-connected twin building and show that the local-to-global principle holds for these twin buildings. As each twin building satisfying Condition (co) (introduced in [7]) is wall-connected, we obtain a strengthening of the main result of [7] that covers also the thick irreducible affine twin buildings of rank at least 3.

We use the method of eigenfamilies to construct explicit complex-valued proper p-harmonic functions on the compact real Grassmannians. We also find proper p-harmonic functions on the real flag manifolds which do not descend onto any of the real Grassmannians.
Compact flexible actuator based on a shape memory alloy for shaping surgical instruments
Authors: Fischer Nikola , Mathis-Ullrich Franziska 
Published: July 2023

Abstract
Conventional flexible actuators for minimally invasive interventions come with complex and bulky actuation infrastructure. We present a proof-of-concept study of a compact flexible actuator with variable shape change featuring shape memory alloy wire loops in active-antagonist configurations for a bending and S-shape. The actuator was fabricated using heat-treated wire loops. The evaluation using optical marker tracking revealed a mean maximum absolute displacement at the distal tip of 19 mm and a force of 90 mN reached in under 15 s. For control, a closed-loop regime was evaluated with steady-state errors below 2°.
Shape-sensing by self-sensing of shape memory alloy instruments for minimal invasive surgery
Authors: Fischer Nikola , Knapp Johannes , Mathis-Ullrich Franziska 
Published: July 2023

Abstract
Shape memory alloy-based flexible instruments have potential for enhancing the safety in minimally invasive surgery compared to passive rigid devices. We developed a data-driven polynomial model to estimate deflection of a 2D bending actuator using electrical resistance. The model accurately predicts deflections (mean error <3.6 mm), but force sensing augmentation is required for unknown load cases. The model is specific to the tested actuator geometry, and future research should investigate multiple actuators and explore nonlinear modeling approaches.
Musculoskeletal model-based control strategy of an over-actuated glenohumeral simulator to assess joint biomechanics

Published: July 2023

Abstract
Determining the acting shoulder and muscle forces in vivo is very complex. In this study, we developed a control strategy for a glenohumeral simulator for ex vivo experiments that can mimic physiological glenohumeral motion and overcome the problem of over-actuation. The system includes ten muscle portions actuated via cables to induce upper arm motion in three degrees of freedom, including scapula rotation. A real-time optimizer was implemented to handle the over-actuation of the glenohumeral joint while ensuring a minimum of muscle tension. The functionality of the real-time optimizer was also used to simulate different extents of rotator cuff tears. Joint reaction forces were consistent with in vivo measurements. These results demonstrate the feasibility and added value of implementing a real-time optimizer for using in vivo data to drive a shoulder simulator.

Berberine suppressed sarcopenia insulin resistance through SIRT1-mediated mitophagy
Authors: Su Xiaojuan , Yang Danqi , Hu Yu , Yuan Ying , Song Le 
Published: July 2023

Abstract
Abnormal mitochondrial function resulting in inadequate energy supply leads to sarcopenia and IR, suggesting that maintaining mitochondrial homeostasis by regulating mitophagy may be a promising strategy for sarcopenia IR therapy. Herein, we constructed sarcopenia mice model, which was treated with berberine and/or SIRT1/mitophagy inhibitors, and the activity of SIRT1/mitophagy signaling pathway was identified. Then, muscle tissue, blood biochemical index, inflammatory factors, GTT, and ITT were detected. We found that berberine treatment increased the body weight and alleviated d-galactose-induced weight loss in mice. SIRT1/mitophagy inhibitors suppressed the effects of berberine in the treatment of sarcopenia. The effect of berberine on the increase of muscle tissue, improving metabolic disorders, reducing the expression of inflammatory factors, and suppressing sarcopenia insulin resistance (IR) were reversed by SIRT1/mitophagy inhibitors. Our study establishes proof-of-concept to distinct the effect of berberine in sarcopenia IR, and provides strong evidence to support the hypothesis that berberine-induced SIRT1 triggers mitochondrial autophagy pathway and suppresses IR in sarcopenia.
