Sensitive and absolute absorption measurements in optical materials and coatings by laser-induced deflection technique

Abstract. The laser-induced deflection (LID) technique, a photo-thermal deflection setup with transversal pump-probe-beam arrangement, is applied for sensitive and absolute absorption measurements of optical materials and coatings. Different LID concepts for bulk and transparent coating absorption measurements, respectively, are explained, focusing on providing accurate absorption data with only one measurement and one sample. Furthermore, a new sandwich concept is introduced that allows transferring the LID technique to very small sample geometries and to significantly increase the sensitivity for materials with weak photo-thermal responses. For each of the different concepts, a representative application example is given. Particular emphasis is placed on the importance of the calibration procedure for providing absolute absorption data. The validity of an electrical calibration procedure for the LID setup is proven using specially engineered surface absorbing samples. The electrical calibration procedure is then applied to evaluate two other approaches that use either doped samples or highly absorptive reference samples.
Dual-Wideband Dual-Polarized Magnetoelectric Dipole Antenna for Sub-6 GHz Applications

This letter presents a dual-wideband dual-polarized magnetoelectric dipole (ME) antenna, which works at the prominent frequency bands of 1.7–2.7 GHz and 3.3–5.0 GHz in Sub-6 GHz. A cross ME dipole excites dual-polarized radiation, and a cross strip under the cross dipole embeds a notched band from 2.7–3.3 GHz. Furthermore, a cross patch above the crossdipole and a metal baffle around the ground improve the wideband impedance matching and stable the radiation pattern. As a result, a prototype of the proposed antenna is fabricated and measured. The measured results exhibit dual-wideband and dual-polarized characteristics of 1.66–2.6 GHz (44.13%) and 3.12–5.08 GHz (47.8%), 1.74–2.64 GHz (41.09%), and 3.34–5.08 GHz (42.08%), and the realized gains of 7 and 9 dBi for the two ports, respectively. The proposed antenna is state-of-the-art for base-station applications in Sub-6 GHz.
The role of Epstein–Barr virus in nasopharyngeal carcinoma

Nasopharyngeal carcinoma (NPC) is a metastasis-prone malignancy closely associated with the Epstein–Barr virus (EBV). Despite ubiquitous infection of EBV worldwide, NPC incidences displayed predominance in certain ethnic groups and endemic regions. The majority of NPC patients are diagnosed with advanced-stage disease, as a result of anatomical isolation and non-specific clinical manifestation. Over the decades, researchers have gained insights into the molecular mechanisms underlying NPC pathogenesis as a result of the interplay of EBV infection with several environmental and genetic factors. EBV-associated biomarkers were also used for mass population screening for the early detection of NPC. EBV and its encoded products also serve as potential targets for the development of therapeutic strategies and tumour-specific drug delivery. This review will discuss the pathogenic role of EBV in NPC and efforts in exploiting the potential of EBV-associated molecules as biomarkers and therapeutic targets. The current knowledge on the role of EBV and its associated products in NPC tumorigenesis, development and progression will offer a new outlook and potential intervention strategy against this EBV-associated malignancy.
Techno-overload and well-being of French small business owners: identifying the flipside of digital technologies

ABSTRACT Technostress is an important by-product of information and communication technologies (ICT). The technostress literature suggests focusing on specific dimensions of technostress, such as techno-overload, which describes when ICT usage demands to work faster and longer. However, only a few studies have dealt with the technostress of small business owners, let alone techno-overload. This is surprising since work overload in general has been identified as an important dimension of job stress for small business owners, and technostress has been identified as an important impediment for workers in general. The aim of the current study is to investigate the effect of techno-overload on well-being outcomes (as a composite measure consisting of physical well-being, mental well-being, sleep quality, burnout, and loneliness) using three data sets of French small business owners. Our results indicate a strong negative correlation between techno-overload and our composite measure of well-being for all three data sets. We interpret our findings for several different disciplines: information systems, small business owners and entrepreneurship, health and well-being, psychology and organization studies. Our data also allow for the identification of contextual effects – the COVID-19 pandemic – since one survey was conducted before, one at the start of, and one during the pandemic.

Factors such as age 50–59 years 18 (29.5%), male 36 (59%), informal education 30 (49.1%), BMI overweight 27 (44.3%), duration of diabetes 4–6 years, 30 (49.2%), and co-morbidities such as hypertension 38 (62.3%) and renal diseases 20 (32.8%), inappropriate diabetic diet 37 (60.7%), and 35 (57.4%) inadequate exercise alcohol consumption 26 (42.6%) were factors interfering glycemic control. Complications related to diabetes were 10 (16.4%) retinopathy and nephropathy, 23 (37.7%) neuropathy, 4 (6.6%) coronary artery disease, 8 (13.1%) foot ulcer, 15 (24.6%) stroke, 5 (8.2%) cataract and their odd ratios (OR-3.627, 7.45, 48.22, 6.18, 12.55, 18.09, 3.913, and 1.07, respectively). Conclusion: There is need to achieve an understanding of the extent of glycemic control in patients with type 2 DM and to see the factors interfering with good and poor glycemic control groups, and as a result, to spot the factors affecting glycemic control
Systematic review of health promotion policies or regulations with CCAT theory

One of the five Ottawa Charter’s means of action is the concept of “healthy public policy,” which is an approach to health promotion that is integrated with public policy. This concept can be used as an approach/method in solving health problems at the broader policy level and involving all sectors comprehensively, not just health promotion at the community level and the partial health sector, so that public health problems can be resolved properly. We conducted a systematic review of health promotion policies or regulations using CCAT theory. The purpose of this study is to find the state of the art of research related to stakeholder synergy in online game addiction prevention policies in adolescents. References and literature for this systematic review were collected from the Proquest, ScienceDirect, Pubmed, and Google Scholar databases. The search uses the boolean phrases “OR” and “AND. ” Keywords: policy or regulation, health promotion, and community coalition action theory. The results of the systematic review conducted by the researchers showed that of the twenty selected articles, three articles used the coalition/partnership dimension from the CCAT theory, four articles used the stakeholder dimension, two articles used the collaboration dimension, five articles discussed school health policies, policies related to gaming disorders. One article on the analysis of the juvenile contraceptive law, one article on the prevention of mental health disorders, one article on health promotion interventions, and two articles on risk factors and self-regulation focus on online gaming addiction in adolescents. This study concludes that in the future, further research is needed regarding health promotion policies to prevent online game addiction in adolescents to develop specific policy recommendations related to preventing online game addiction in adolescents.

Collapsibility of Graphical CG‐Regression Models

Abstract. CG‐regressions are multivariate regression models for mixed continuous and discrete responses that result from conditioning in the class of conditional Gaussian (CG) models. Their conditional independence structure can be read off a marked graph. The property of collapsibility, in this context, means that the multivariate CG‐regression can be decomposed into lower dimensional regressions that are still CG and are consistent with the corresponding subgraphs. We derive conditions for this property that can easily be checked on the graph, and indicate computational advantages of this kind of collapsibility. Further, a simple graphical condition is given for checking whether a decomposition into univariate regressions is possible.
Enhanced magnetoelectric effect in a stress-biased lead magnesium niobate-lead titanate single crystal/Terfenol-D alloy magnetoelectric sensor

A stress-biased magnetoelectric sensor with a built-in permanent magnet has been fabricated using piezoelectric lead magnesium niobate-lead titanate single crystal and magnetostrictive Terfenol-D alloy. The resonance characteristics and magnetoelectric performance of the sensor have been evaluated under different stress-biased conditions. The resonance of the sensor shifts to higher frequency with increasing preloading stress. Due to the piezoelectric and magnetostrictive enhancements under preload, the device exhibits a giant magnetoelectric voltage coefficient of 0.22 V/Oe at a preloading stress of 2.5 MPa. This compact device has the potential to be used as a standalone sensor without requiring external power input.
Time Evolution of the Modulus of Elasticity of Metakaolin-Based Geopolymer

The objective of the research is to develop a new family of geopolymeric materials and to use an experimental methodology to characterize the mechanical behavior of the materials obtained by alkaline activation of metakaolin using a compound activator. The researchers also intend to study the unknown time evolution of the modulus of elasticity and the influence of the composition of the aggregates on the strength of the material. Like the material’s strength, the results have a direct influence on structural safety evaluations. For the analysis of the mechanical properties of the mixtures, different types of tests were carried out: Flexural and compression tests on parallelepipeds and compression tests on cylinders were performed to assess the main strength characteristics of metakaolin-based geopolymers. Regarding the aggregate composition, the results show that the correction of the aggregate particle size line did not improve the mechanical properties. From about 400 h of curing, at ambient temperatures, the mechanical properties of the geopolymeric material are almost invariable. The highest value of the elastic modulus of elasticity occurs around 420 h, at about 18 GPa. The modulus of elasticity is independent of test load rate as per standards, and 1.7‰ strain was observed during maximum compressive stresses in the rupture tests. Also, the secant modulus values at 60% and 80% of maximum stress are within 12% of the value at 40% of maximum stress.
Applicability of Infrared Emission and Absorption Spectra to Determination of Hot Gas Temperature Profiles

Changes in infrared emission and absorption spectra of hot gases brought about by controlled variations of gas temperature profile were measured. Spectral emission-absorption temperatures were determined from the spectral data as a function of wavelength, using the Kirchhoff and Planck laws. These temperatures proved independent of wavelength for an isothermal profile, despite a large variation of absorptance with wavelength. For nonisothermal profiles, the emission-absorption temperature varied with wavelength in a characteristic manner for each profile. These results established more firmly the validity of the infrared emission-absorption technique of gas temperature measurement, and confirmed a previous hypothesis that the wavelength dependence of spectrally determined temperature, observed for most flames, is a temperature profile effect. The spectral emittance equation for a gas was formulated in terms of observable quantities for isothermal and nonisothermal cases, taking the spectrometer slit function into account.

Mode locked figure eight lasers

The figure eight laser (F8L) by the nature of its design provides the possibility for an intensity dependent element inside the cavity. It is this element which allows the laser to self-modelock, producing pulses as short as 90 fs. The laser is a special case of the additive pulse modelocked laser, hut operates in a regime where most of the analysis for that laser breaks down, namely, large changes in the pulse in one round trip. For these reasons much effort has gone into the study of the figure eight fiber laser since it was first introduced in 1990. The overall design of the laser is that of a ring cavity with a Sagnac interferometer incorporated in the cavity. This gives the laser the characteristic shape with one loop the Sagnac interferometer, and the other loop the ring laser. <<ETX>>
Incidence of hyperthyroidism in patients with bipolar or schizoaffective disorder with or without lithium: 21-year follow-up from the LiSIE retrospective cohort study

Background: Lithium-associated hyperthyroidism is much rarer than lithium-associated hypothyroidism. Yet, it may be of substantial clinical significance for affected individuals. For instance, lithium-associated hyperthyroidism could destabilise mood, mimic manic episodes and impact physical health. Only few studies have explored incidence rates of lithium-associated hyperthyroidism. Even fewer studies have compared incidence rates according to lithium exposure history. Objectives: To determine the impact of lithium treatment on the incidence rate of hyperthyroidism in patients with bipolar or schizoaffective disorder and assess its aetiology. Design: This study is part of the LiSIE (Lithium – Study into Effects and Side Effects) retrospective cohort study. Methods: Between 1997 and 2017, patients in the Swedish region of Norrbotten with a diagnosis of bipolar or schizoaffective disorder were screened for all episodes of overt hyperthyroidism in form of thyrotoxicosis or thyroiditis. Incidence rates of episodes of hyperthyroidism per 1000 person-years (PY) were compared in relation to lithium exposure; concurrent, previous, or no exposure ever (lithium-naïve patients) Results: In 1562 patients, we identified 16 episodes of hyperthyroidism corresponding to an incidence rate of 0.88 episodes per 1000 PY. Ninety-four percent of episodes had occurred in women. Patients who had concurrently been exposed to lithium, had an incidence rate of 1.35 episodes per 1000 PY. Patients who had previously been exposed to lithium had an incidence rate of 0.79 per 1000 PY. Patients who had never been exposed to lithium had an incidence rate of 0.47 per 1000 PY. There were no significant differences in the risk ratios for patients with concurrent or previous exposure compared with lithium-naïve patients, neither for hyperthyroidism overall, thyrotoxicosis, or thyroiditis. Conclusion: Lithium-associated hyperthyroidism seems uncommon. The risk of hyperthyroidism does not seem significantly higher in patients with current or previous lithium exposure than in lithium-naïve patients.
Targeting β-glucans, vital components of the Pneumocystis cell wall

β-glucan is the most abundant polysaccharide in the cell wall of Pneumocystis jirovecii, which has attracted extensive attention because of its unique immunobiological characteristics. β-glucan binds to various cell surface receptors, which produces an inflammatory response and accounts for its immune effects. A deeper comprehension of the processes by Pneumocystis β-glucan recognizes its receptors, activates related signaling pathways, and regulates immunity as required. Such understanding will provide a basis for developing new therapies against Pneumocystis. Herein, we briefly review the structural composition of β-glucans as a vital component of the Pneumocystis cell wall, the host immunity mediated by β-glucans after their recognition, and discuss opportunities for the development of new strategies to combat Pneumocystis.
Gain-Improved Wideband Circularly Polarized Magnetoelectric Dipole Antenna With Parasitic Helix

This communication presents a magnetoelectric (ME) dipole antenna with wideband circularly polarized (CP) and gain-improved performance. Two pairs of perpendicular sub-ME dipoles, which are realized by horizontal and vertical patches, constitute the original ME dipole. By connecting one pair of sub-ME dipole with metallic strip, CP operation is achieved at lower band first. Then, we change the coupling slot from rectangle to cross, which leads to the enhancement of impedance and axial-ratio (AR) bandwidth. Furthermore, a helix with different turn radii and uniform turn spacing is introduced to improve the gain in the whole band. The performance of the proposed design is verified by measured results. The fabricated antenna exhibits a −10 dB impedance bandwidth of 3.33–6.75 GHz, corresponding to 67.9%. Besides, the measured 3 dB AR bandwidth and 3 dB gain bandwidth are 3.6–6.25 GHz (53.8%) and 3.4–5.8 GHz (52.2%), respectively. The proposed design could provide promising application values for wideband wireless communication systems.
A Dual-Branch Deep Learning Architecture for Multisensor and Multitemporal Remote Sensing Semantic Segmentation

Multisensor data analysis allows exploiting heterogeneous data regularly acquired by the many available remote sensing (RS) systems. Machine- and deep-learning methods use the information of heterogeneous sources to improve the results obtained by using single-source data. However, the state-of-the-art methods analyze either the multiscale information of multisensor multiresolution images or the time component of image time series. We propose a supervised deep-learning classification method that jointly performs a multiscale and multitemporal analysis of RS multitemporal images acquired by different sensors. The proposed method processes very-high-resolution (VHR) images using a residual network with a wide receptive field that handles geometrical details and multitemporal high-resolution (HR) image using a 3-D convolutional neural network that analyzes both the spatial and temporal information. The multiscale and multitemporal features are processed together in a decoder to retrieve a land-cover map. We tested the proposed method on two multisensor and multitemporal datasets. One is composed of VHR orthophotos and Sentinel-2 multitemporal images for pasture classification, and another is composed of VHR orthophotos and Sentinel-1 multitemporal images. Results proved the effectiveness of the proposed classification method.
A pipeline scheme for real-time traffic in optical burst switching networks

Optical burst switching (OBS) is regarded as a promising optical switching paradigm for next generation optical Internet. More and more real-time traffic is transported by IP and it is important for OBS to support real-time traffic. Based on the delay analysis of OBS networks, a pipeline scheme is proposed to reduce the delay and efficiently support real-time traffic for OBS networks in the paper. When real-time traffic is transported in the core nodes of the established pipeline and its burst head packet can not need to be processed. So the pipeline scheme reduces the offset time and delay of realtime traffic. The simulation result shows that the pipeline scheme effectively reduces the end-to-end delay of real-time traffic in the OBS networks.
