Published: February 2023

In the linear instability analysis of the difference-differential equation which describes the dynamic behaviors of optical bistability with delayed feedback, introducing degree of stability S, which is defined as the ratio between relative variations of input and output intensities(1), we find that for long delay time instability condition is S≥2 and possible oscillation periods are approximately

but for short delay time the condition is S≥1 + πτ/2T and the periods are

. So the generation of instability for long delay time is easier than for short one, as shown in Fig.1.
Cost-effectiveness of human T-cell leukemia virus type 1 (HTLV-1) antenatal screening for prevention of mother-to-child transmission
Authors: Kowada Akiko 
Published: February 2023

Background
Human T-cell leukemia virus type 1 (HTLV-1) causes adult T-cell leukemia-lymphoma (ATL) and HTLV-1-associated myelopathy-tropical spastic paraparesis (HAM/TSP) with a poor prognosis. This study aimed to evaluate the cost-effectiveness and health impact of HTLV-1 antenatal screening.

Methodology/Principal findings
A state-transition model was developed for HTLV-1 antenatal screening and no screening over a lifetime horizon from a healthcare payer perspective. A hypothetical cohort of 30-year-old individuals was targeted. The main outcomes were costs, quality-adjusted life-years (QALYs), life expectancy life-years (LYs), incremental cost-effectiveness ratios (ICERs), HTLV-1 carriers, ATL cases, HAM/TSP cases, ATL-associated deaths, and HAM/TSP-associated deaths. The willingness-to-pay (WTP) threshold was set at US$50,000 per QALY gained. In the base-case analysis, HTLV-1 antenatal screening (US$76.85, 24.94766 QALYs, 24.94813 LYs, ICER; US$40,100 per QALY gained) was cost-effective compared with no screening (US$2.18, 24.94580 QALYs, 24.94807 LYs). Cost-effectiveness was sensitive to the maternal HTLV-1 seropositivity rate, HTLV-1 transmission rate with long-term breastfeeding from HTLV-1 seropositive mothers to children, and the cost of the HTLV-1 antibody test. HTLV-1 antenatal screening was cost-effective when the maternal HTLV-1 seropositivity rate was greater than 0.0022 and the cost of the HTLV-1 antibody test was lower than US$94.8. Probabilistic sensitivity analysis using a second-order Monte-Carlo simulation showed that HTLV-1 antenatal screening was 81.1% cost-effective at a WTP threshold of US$50,000 per QALY gained. For 10,517,942 individuals born between 2011 and 2021, HTLV-1 antenatal screening costs US$785 million, increases19,586 QALYs and 631 LYs, and prevents 125,421 HTLV-1 carriers, 4,405 ATL cases, 3,035 ATL-associated deaths, 67 HAM/TSP cases, and 60 HAM/TSP-associated deaths, compared with no screening over a lifetime.

Conclusion/Significance
HTLV-1 antenatal screening is cost-effective and has the potential to reduce ATL and HAM/TSP morbidity and mortality in Japan. The findings strongly support the recommendation for HTLV-1 antenatal screening as a national infection control policy in HTLV-1 high-prevalence countries.

Authors: Bolliger Larissa , Baele Ellen , Colman Elena , Debra Gillian , Lukan Junoš , Luštrek Mitja , De Bacquer Dirk , Clays Els 
Published: February 2023

Objectives
This study aimed to investigate the associations between day-to-day work-related stress exposures (i.e., job demands and lack of job control), job strain, and next-day work engagement among office workers in academic settings. Additionally, we assessed the influence of psychological detachment and relaxation on next-day work engagement and tested for interaction effects of these recovery variables on the relationship between work-related stressors and next-day work engagement.

Methods
Office workers from two academic settings in Belgium and Slovenia were recruited. This study is based on an Ecological Momentary Assessment (EMA) with a 15-working day data collection period using our self-developed STRAW smartphone application. Participants were asked repeatedly about their work-related stressors, work engagement, and recovery experiences. Fixed-effect model testing using random intercepts was applied to investigate within- and between-participant levels.

Results
Our sample consisted of 55 participants and 2710 item measurements were analysed. A significant positive association was found between job control and next-day work engagement (β = 0.28, p < 0.001). Further, a significant negative association was found between job strain and next-day work engagement (β = −0.32, p = 0.05). Furthermore, relaxation was negatively associated with work engagement (β = −0.08, p = 0.03).

Conclusions
This study confirmed previous results, such as higher job control being associated with higher work engagement and higher job strain predicting lower work engagement. An interesting result was the association of higher relaxation after the working day with a lower next-day work engagement. Further research investigating fluctuations in work-related stressors, work engagement, and recovery experiences is required.

Published: February 2023

Introduction
This study aims to describe the epidemiological characteristics of imported cases of dengue (DEN), chikungunya (CHIK), and Zika virus (ZIKV) infections in Czech travellers.

Materials and methods
This single-centre descriptive study has retrospectively analysed data of patients with laboratory confirmed DEN, CHIK, and ZIKV infections diagnosed at the Department of Infectious, Parasitic and Tropical Diseases of the University Hospital Bulovka in Prague, Czech Republic from 2004 to 2019.

Results
The study included a total of 313 patients with DEN, 30 with CHIK, and 19 with ZIKV infections. Most patients travelled as tourists:263 (84.0%), 28 (93.3%), and 17 (89.5%), respectively (p = 0.337). The median duration of stay was 20 (IQR 14–27), 21 (IQR 14–29), and 15 days (IQR 14–43), respectively (p = 0.935). Peaks of imported DEN and ZIKV infections were noted in 2016, and in 2019 in the case of CHIK infection. Most cases of DEN and CHIKV infections were acquired in Southeast Asia:212 (67.7%) and 15 (50%), respectively, while ZIKV infection was most commonly imported from the Caribbean (11; 57,9%).

Conclusions
Arbovirus infections represent an increasingly significant cause of illness in Czech travellers. Comprehensive knowledge of the specific epidemiological profile of these diseases is an essential prerequisite for good travel medicine practice.

Published: February 2023

Objective
Posterior full-endoscopic cervical foraminotomy (PECF) is one of minimally invasive surgical techniques for cervical radiculopathy. Because of minimal disruption of posterior cervical structures, such as facet joint, cervical kinematics was minimally changed. However, a larger resection of facet joint is required for cervical foraminal stenosis (FS) than disc herniation (DH). The objective was to compare the cervical kinematics between patients with FS and DH after PECF.

Methods
Consecutive 52 patients (DH, 34 vs. FS, 18) who underwent PECF for single-level radiculopathy were retrospectively reviewed. Clinical parameters (neck disability index, neck pain and arm pain), and segmental, cervical and global radiological parameters were compared at postoperative 3, 6, and 12 months, and yearly thereafter. A linear mixed-effect model was used to assess interactions between groups and time. Any occurrence of significant pain during follow-up was recorded during a mean follow-up period of 45.5 months (range 24–113 months).

Results
Clinical parameters improved after PECF, with no significant differences between groups. Recurrent pain occurred in 6 patients and surgery (PECF, anterior discectomy and fusion) was performed in 2 patients. Pain-free survival rate was 91% for DH and 83% for FS, with no significant difference between the groups (P = 0.29). Radiological changes were not different between groups (P > 0.05). Segmental neutral and extension curvature became more lordotic. Cervical curvature became more lordotic on neutral and extension X-rays, and the range of cervical motion increased. The mismatch between T1-slope and cervical curvature decreased. Disc height did not change, but the index level showed degeneration at postoperative 2 years.

Conclusion
Clinical and radiological outcomes after PECF were not different between DH and FS patients and kinematics were significantly improved. These findings may be informative in a shared decision-making process.
¿Por qué varía el desempeño entre estudiantes de baja condición social? Factores escolares y domésticos asociados al logro en seis países sudamericanos
Authors: Miguez Daniel Pedro 
Published: February 2023

Este artículo examina las condiciones domésticas y escolares asociadas a los puntajes obtenidos en las pruebas PISA 2018 por los y las estudiantes de menores recursos en seis países sudamericanos: Argentina, Brasil, Chile, Colombia, Perú y Uruguay. A diferencia de los estudios que comparan estudiantes de diversos estratos sociales, comparamos las características de las escuelas y los hogares donde los/as estudiantes que pertenecen a los estratos más carecientes logran mayores puntajes en las pruebas con aquellas en las que logran puntajes más bajos. Esta comparación pone en evidencia que existen variaciones en la disponibilidad de recursos educativos en el hogar de estudiantes del mismo estrato que se asocian al desempeño. También existen actitudes estudiantiles desfavorables al aprendizaje (como el escaparse de clases, ausentarse o el bullying entre compañeros) que afectan los aprendizajes. En cambio, la disponibilidad de recursos pedagógicos o de infraestructura en las escuelas, y las actitudes docentes frente al aprendizaje no presentan una asociación estadísticamente robusta.
Nezha

Published: February 2023

This paper presents a high-performance consensus protocol, Nezha, which can be deployed by cloud tenants without support from cloud providers. Nezha bridges the gap between protocols such as Multi-Paxos and Raft, which can be readily deployed, and protocols such as NOPaxos and Speculative Paxos, that provide better performance, but require access to technologies such as programmable switches and in-network prioritization, which cloud tenants do not have.
Nezha uses a new multicast primitive called deadline-ordered multicast (DOM). DOM uses high-accuracy software clock synchronization to synchronize sender and receiver clocks. Senders tag messages with deadlines in synchronized time; receivers process messages in deadline order, on or after their deadline.
We compare Nezha with Multi-Paxos, Fast Paxos, Raft, (optimized) NOPaxos, and 2 recent protocols, Domino and TOQ-EPaxos, that use synchronized clocks. In throughput, Nezha outperforms all baselines by a median of 5.4X (range: 1.9--20.9X). In latency, Nezha outperforms five baselines by a median of 2.3X (range: 1.3--4.0X), with one exception: it sacrifices 33% of latency compared with our optimized NOPaxos in one test. We also prototype two applications, a key-value store and a fair-access stock exchange, on top of Nezha to show that Nezha only modestly reduces their performance relative to an unreplicated system.

Dynamical aspects of transient electro-osmotic flow of Burgers' fluid with zeta potential in cylindrical tube
Authors: Raza Nauman , Khan Ahmad Kamal , Awan Aziz Ullah , Abro Kashif Ali 
Published: February 2023

Abstract
In this article, we consider the flow of a Burgers’ fluid of transient electro-osmotic type in a small tube with a circular cross-section. Analytical results are found for the transient velocity and, electric potential profile by solving the Navier–Stokes and the linearized Poisson–Boltzmann equations. Moreover, these equations are solved with the help of the integral transform method. We consider cases in which the velocity of the fluid changes with time and those in which the velocity of the fluid does not change with time. Furthermore, special results for classical fluids such as Newtonian, second grade, Maxwell, and Oldroyd-B fluids are obtained as the particular cases of the outcomes of this work and that these results actually strengthen the results of the solution. This study of the nonlinear problem of Burgers’ fluid in a specified physical model will help us to understand the behavior of blood clotting and the block of any kind of problem in which this type of fluid is used. The solution of the complex velocity profile of Burgers’ fluid will help us in the future to solve the problems in which this transient electro-osmotic type of small tube is involved. At the end, numerical results are shown graphically that can help us to understand the complex behavior of the Burgers’ fluid, and also the analysis of the Burgers’ fluid shows dissimilarity with other fluids that are considered in this work.

Published: February 2023

Abstract
This article continues a discussion the authors have had with Mats Wahlberg on evolutionary theodicies. We have previously suggested a theodicy where there are token unique goods that could only have been actualized through indeterministic evolution. Wahlberg objects that we cannot appeal to such goods, since given indeterminism, God cannot know that such goods will appear. In this article we respond by arguing that God can know well enough that certain kinds of token goods will appear, without knowing in detail their specific character, or when they will happen.
A comparative assessment of potentially harmful metals in the Lagos Lagoon and Ogun river catchment
Authors: Adeniyi Adeleke , Ibidokun Mayowa , Oluwole Ojo 
Published: February 2023

Abstract
Metals are one of the most common pollutants of surface water around the world. The anthropogenic contribution to aquatic metal pollution is of global concern. This study investigates the levels of Ca, Cd, Cu, Fe, Mn, Pb, Ni and Zn in surface water and sediments in the Lagos lagoon (Ibafon-Apapa, University of Lagos waterfront, UWF) and Ogun river catchment at Agiliti-Ketu. The metal concentrations were determined using atomic absorption spectrophotometry. Ibafon-Apapa generally, accounted for the highest concentrations of metals in both water and sediment samples. The ranges of concentrations (µg/g) of metals in sediment samples were: 0.08 ± 0.05–2140.64 ± 1981.54, ND-7.19 ± 7.32, 4.59 ± 2.46–78.95 ± 49.15, 3276.22 ± 2059.57–25,307.60 ± 8759.66, 255.73 ± 98.54–4651.0 ± 1672.60, 19.84 ± 10.23–228.50 ± 84.17, 4.51 ± 4.02–24.45 ± 22.78 for Ca, Cd, Cu, Fe, Mn, Pb and Zn, respectively. Ni occurred in the water and sediment samples below the detection limit. The water and sediments samples from UWF have mean pH values of 7.71 ± 0.07 and 6.61 ± 0.40, respectively, which are higher than that of Agiliti-Ketu (7.65 ± 0.06 and 6.58 ± 0.95) and Ibafon-Apapa (7.60 ± 0.39 and 4.20 ± 0.50), respectively. The highest values for electrical conductivity (EC) was recorded in Ibafon-Apapa (8.54 ± 1.27 μS/cm) followed by UWF (6.50 ± 2.16 μS/cm) and Agiliti-Ketu (0.28 ± 0.40 μS/cm), respectively. The relatively high values of EC and total dissolved solids (TDS) in the Ibafon-Apapa and UWF axis of the Lagos lagoon is an indication of the brackish nature of the lagoon, while the low mean values of EC (0.28 ± 0.40 μS/cm) and TDS (78.0 ± 13.04 mg/L) recorded for Agiliti-Ketu is a pointer to the freshwater attribute of the water. Cd, Mn, Fe and Pb were found to exceed the WHO limit for drinking water. Results were compared with global background values. Cadmium, manganese, iron and lead levels in the water and sediments samples revealed metals pollution. Statistical analysis of variance and t-test were used to analyze the data obtained. Metals pollution source control is recommended.

Abstract
Studies are still being conducted to find a sustainable and long-lasting solution to the lethal consequences of the feared virus characterized as coronavirus disease (Covid-19) and its accompanying pathogenic replication, which pose a serious threat to human survival in the wake of its broad distribution. Since its emergence, researchers have investigated synthetic approaches in search of a dependable vaccine or treatment and curtail the spread of the virus and also enhance the health of a patient who has been affected. Unfortunately, the infection is yet to be entirely eradicated in many parts of the world. Despite the introduction of synthetic pharmaceuticals like remdesivir and derivatives of chloroquine, plant extracts may be an alternative reliable strategy that could successfully combat the operation of the virus. Herein, we investigated the prospects of fagara zanthoxyloides lam. (rutaceae) (syn. zanthoxylum zanthoxyloides), a well-known medicinal tree whose extracts have demonstrated success in treating many microbiological and viral-related infections. The distinctive plant extracts contain several bioactive phytochemicals with promising biological activity with minimal or no side effects and are being researched for a variety of applications, particularly in the pharmaceutical and medicinal industries. Consequently, in this review, we examined the crude extracts from the Fagara species and suggested that careful consideration should be given to its independent use or combination with other bioactive molecules, such as biopolymers and nano-metallic composites, to combat the terrifying Covid-19 virus and its associates.
In search of a musical past: evidence for early chordophones from Vietnam
Authors: Campos Fredeliza Z. , Hull Jennifer R. , Hồng Vương Thu 
Published: February 2023

ABSTRACTMusic likely played an important role within prehistoric societies but can be challenging to study in the absence of evidence for musical instruments. Here, the authors present two deer antlers recovered from the early Metal Age site of Go O Chua in southern Vietnam. A detailed examination of the artefacts, including evidence for use-wear, combined with insights from ethnographic analogies, leads the authors to conclude that the artefacts were single-stringed musical instruments. At least 2000 years old, the Go O Chua artefacts would be the earliest-known examples of chordophones from the region and indicate a long musical tradition. Their identification gives impetus to archaeo-musicological research in Southeast Asia and beyond.

Resident cochlear macrophages rapidly migrate into the inner hair cell synaptic region and directly contact the damaged synaptic connections after noise-induced synaptopathy. Eventually, such damaged synapses are spontaneously repaired, but the precise role of macrophages in synaptic degeneration and repair remains unknown. To address this, cochlear macrophages were eliminated using colony stimulating factor 1 receptor (CSF1R) inhibitor, PLX5622. Sustained treatment with PLX5622 inCX3CR1GFP/+mice of both sexes led to robust elimination of resident macrophages (∼94%) without significant adverse effects on peripheral leukocytes, cochlear function, and structure. At 1 day (d) post noise exposure of 93 or 90 dB SPL for 2 hours, the degree of hearing loss and synapse loss were comparable in the presence and absence of macrophages. At 30 d after exposure, damaged synapses appeared repaired in the presence of macrophages. However, in the absence of macrophages, such synaptic repair was significantly reduced. Remarkably, on cessation of PLX5622 treatment, macrophages repopulated the cochlea, leading to enhanced synaptic repair. Elevated auditory brainstem response thresholds and reduced auditory brainstem response Peak 1 amplitudes showed limited recovery in the absence of macrophages but recovered similarly with resident and repopulated macrophages. Cochlear neuron loss was augmented in the absence of macrophages but showed preservation with resident and repopulated macrophages after noise exposure. While the central auditory effects of PLX5622 treatment and microglia depletion remain to be investigated, these data demonstrate that macrophages do not affect synaptic degeneration but are necessary and sufficient to restore cochlear synapses and function after noise-induced synaptopathy.SIGNIFICANCE STATEMENTThe synaptic connections between cochlear inner hair cells and spiral ganglion neurons can be lost because of noise over exposure or biological aging. This loss may represent the most common causes of sensorineural hearing loss also known as hidden hearing loss. Synaptic loss results in degradation of auditory information, leading to difficulty in listening in noisy environments and other auditory perceptual disorders. We demonstrate that resident macrophages of the cochlea are necessary and sufficient to restore synapses and function following synaptopathic noise exposure. Our work reveals a novel role for innate-immune cells, such as macrophages in synaptic repair, that could be harnessed to regenerate lost ribbon synapses in noise- or age-linked cochlear synaptopathy, hidden hearing loss, and associated perceptual anomalies.
