Analytical and comparative study of LPGs manufactured using electric-arc and UV micromachining methods

An analytical model for long-period grating manufactured using an electric-arc micromachining method is developed. This model takes into account the resulting modulation of the refractive index and the diameter in both the core and the cladding of the fiber structure. Based on the local-mode theory, the model introduces coupling coefficients and detuning parameters that vary longitudinally. Comparisons are made with the standard model for long-period grating manufactured using the UV micromachining method.
Semiparametric inference in a partial linear model

In a partial linear model, the dependence of a response variate Y on covariates (W, X$ is given by $$Y = W \beta + \eta(X) + \mathscr{E}$$ where $\mathscr{E}$ is independent of $(W, X)$ with densities g and f, respectively. In this paper an asymptotically efficient estimator of $\beta$ is constructed solely under mild smoothness assumptions on the unknown $\eta$, f and g, thereby removing the assumption of finite residual variance on which all least-squares-type estimators available in the literature are based.
Effect of the phase space factor in the breakup of composite particles

The need to include the phase space factor in the analysis of . cap alpha. breakup spectra according to Fermi's Golden Rule is indicated. The importance of the number of particles present in the final state is exemplified by a model calculation for proton, deuteron, and triton spectra produced by the breakup of 160 MeV alphas on zirconium.
Accurate matching method of multimodal image based on phase congruency and local mutual information

Multimodal image matching is difficult because of the contrast and intensity difference of the images. For solving this problem, a new matching method based on the phase congruency, histograms of oriented gradients and local normalized mutual information was proposed. The proposed method first extract feature points and edge map based on monogenic signal and phase congruency method which is insensitivity to variations in illumination and contrast. Then, the Monogenic Phase Congruency Edge Descriptor based on edge orientation histogram was generated by gathering the edge information of orientations from edge map around the feature point. For increasing the matched point-pair number, the Multi Candidate Point Matching Method by selecting multi better candidate matching points for each feature point was presented. Finally, the location accuracy was refined using local normalized mutual information method. The experimental results indicated that the proposed method could achieve higher performance in heterogonous image matching, the average matching correct rate up to 88%, is about 3 times of SURF matching method.

Relationship between chlorophyll-a, sea surface temperature and sea surface salinity

BACKGROUND AND OBJECTIVES: This study aimed to investigate the long-term relationship between chlorophyll-a, sea surface temperature, and sea surface salinity monthly from January 2015 to December 2021. It was carried out in the Northern Bay of Bengal, which experiences extreme monsoons, in the southwest monsoon and northeast monsoon from June to September and November to February, respectively. Monsoon is the main cause of changes in chlorophyll-a, sea surface temperature and sea surface salinity. METHODS: The seasonal model was used to examine the relationship between these three parameters, which were obtained using the Copernicus Marine Environment Monitoring Service data. The seasonal model was used to observe periodic patterns and predict parameters based on their regularity. Meanwhile, Pearson’s correlation analysis was conducted to determine the relationship between chlorophyll-a, sea surface temperature and sea surface salinity. FINDINGS: This study found that the three parameters, namely chlorophyll-a, sea surface temperature, and sea surface salinity, follow the monsoon pattern, as shown in the seasonal model. The minimum value of chlorophyll-a occurred in February, March and April, while the maximum value of approximately 2 milligram per cubic meter occured at stations 1, 2, 3, 4, 5 and 7, but at 9 and 10, it increased to 12 - 14 mg/m3. This indicates that station positions are very sensitive to changes in chlorohophyll-a values. When the southwest monsoon occurred, it reached the maximum. Furthermore, the minimum sea surface temperature values occurred in January and at almost every station in the year. It was shown to be associated with the northeast monsoon, which causes winter. On the sea surface temperature graph, several peaks were observed in positive local extremes yearly at almost all stations. The maximum sea surface temperature occurred in May, June, and July, according to the shape of the graph, which peaked in the middle of the year. The sea surface salinity graph formed a peak and valley which occurred yearly in May or April, as well as September and October, respectively. CONCLUSION: Chlorophyll-a had 1 trough and 1 peak, with the sea surface temperature graph possessing only 1 peak, while the sea surface salinity graph had 1 peak and 1 trough, respectively. These graph patterns implied that chlorophyll-a first achieved a minimum value before reaching the máximum. The sea surface temperature graph had a maximum value in the middle of the year, while the minimum occurred at the beginning or end. Moreover, the sea surface salinity graph first reached the maximum value and then declined to the minimum.
Glow curve analysis of the 110°C glow peak of quartz in the simplified GOT equation

A recently developed glow curve deconvolution technique which employs the Hybrid Genetic Algorithm has been applied to the 110°C glow peak of quartz. This technique enables one to determine the key intrinsic trapping parameters, namely, the activation energy (E), the frequency factor (s) and the ratio of retrapping probability to recombination probability ( α ). The analysis shows that the 110°C glow peak of quartz has trap depth of 0.974±0.002 eV, frequency factor of (5.27 ± 0.06) x 10 12 sec -1 and retrapping to recombination ratio in the range of 3x10 -4 ≤ α≤ 3x10 -2. It is proved that retrapping is not negligible; rather it is ≈ 1/10000 to 1/100 times the recombination probability. The value of N suggests that the trap created by beta irradiation is not linear.
Breathing Pattern Disorders Distinguished from Healthy Breathing Patterns Using Oxptoelectronic Plethysmography

Tere is no gold standard diagnostic method for breathing pattern disorders (BPD) which is commonly diagnosed through the exclusion of other pathologies. Optoelectronic plethysmography (OEP) is a 3D motion capture technique that provides a comprehensive noninvasive assessment of chest wall during rest and exercise. Te purpose of this study was to determine if OEP can distinguish between active individuals classifed with and without BPD at rest and during exercise. Forty-seven individuals with a healthy breathing pattern (HBP) and twenty-six individuals with a BPD performed a submaximal exercise challenge. OEP measured the movement of the chest wall through the calculation of timing, percentage contribution, and phase angle breathing pattern variables. A mixed model repeated measures ANOVA analysed the OEP variables between the groups classifed as HBP and BPD at rest, during exercise, and after recovery. At rest, regional contribution variables including ribcage percentage contribution (HBP: 71% and BPD: 69%), abdominal ribcage contribution (HBP: 13% and BPD: 11%), abdomen percentage contribution (HBP: 29% and BPD: 31%), and ribcage and abdomen volume index (HPB: 2.5 and BPD: 2.2) were signifcantly ( p < 0 . 05 ) diferent between groups. During exercise, BPD displayed signifcantly ( p < 0 . 05 ) more asynchrony between various thoracic compartments including the ribcage and abdomen phase angle (HBP: − 1.9 and BPD: − 2.7), pulmonary ribcage and abdomen phase angle (HBP: − 0.5 and BPD, 0.5), abdominal ribcage and shoulders phase angle (HBP: − 0.3 and BPD: 0.6), and pulmonary ribcage and shoulders phase angle (HBP: 0.2 and BPD: 0.6). Additionally, the novel variables inhale deviation (HBP: 8.8% and BPD: 19.7%) and exhale deviation (HBP: − 10.9% and BPD: − 17.6%) were also signifcantly ( p < 0 . 05 ) diferent between the groups during high intensity exercise. Regional contribution and phase angles measured via OEP can distinguish BPD from HBP at rest and during exercise. Characteristics of BPD include asynchronous and thoracic dominant breathing patterns that could form part of future objective criteria for the diagnosis of BPD.
The structure of a supersonic turbulent boundary layer subjected to concave surface curvature

This paper reports an experimental investigation of the instantaneous structure of a supersonic turbulent boundary layer (M = 2.86, Reθ = 82000) over a short region of longitudinal concave surface curvature. The radius of curvature was 12 initial boundary-layer thicknesses and the turning angle was 16°. Severe distortion of the boundary layer occurred, as evidenced by an alteration of the mean velocity profiles and an increase in wall shear stress of 125%. The large-scale organized motions in the boundary layer were significantly altered as illustrated by changes in the character of the mass flux ‘fronts’ (large gradients in the fluctuating streamwise mass flux).
Factors influencing habitat choice of bird species: a comparison of a natural and an artificial wetland

Between 2019 and 2022, we studied the avifauna and environmen­ tal conditions of two wetland habitats located in close proximity to each other in Transcarpathia (nearby to the village of Dyida, Za kar patska Oblast, Ukraine) — one being a natural, currently protec ted but drying and highly degraded former bog (Tóvár Or­ nithological Reserve), whereas the other one being an artificial pit lake (Lake Dyida). Lake Dyida is used as recreation area during the summer nesting season of birds. Both of these wetlands bor­ der with agricultural lands. Bird species that occur in both of the investigated habitats are affected by severe anthropogenic distur­ bances. A total of 27 795 individuals of 58 bird species were ob­ served in the two areas over the four study years. Results indicate that the species composition of the two study sites differed consid­ erably, both on annual and seasonal basis. Seasonal precipitation totals strongly influence the current spatial ratios of terrestrial and waterbird species, and show a strong positive correlation with the seasonal total number of bird species. Maximum numbers of birds are recorded in spring and summer at Tóvár and in autumn and winter at Lake Dyida. In the case of Lake Dyida, these could partly be due to the autumn–winter appearance of migratory waterbirds and the end of the beach season. Despite the impact of numer­ ous anthropogenic factors and habitat distrubances, the natural wetland is much more species­rich even in its degraded condition than the artificial wetland, which has been confirmed not only for bird species but also for plant species in the two areas. Duck species consider the deep­water pit lake as an alternative habitat during periods of drought, but for waders the great water depth makes this site less exploitable. In Europe, too, drying out due to seasonal precipitation shortages is an issue of increasing concern, especially for wetlands beacuse artificially maintained lakes and reservoirs cannot fully take over the role of natural lakes, marshes and bogs, which will have severe consequences in the future.
The Effects of Technostress on Well-Being and Performance. The Role of Social Support A study among childcare workers in the Netherlands

The recent technological revolution has brought consistent changes in the modern workplace. Although it has allowed work to be performed faster and in a more efficient way, many employees are not completely at ease with its implementation since fast-changing ICT can be overwhelming. As a result, users have started to experience stress deriving from technology (technostress), which has negative consequences on individuals. Making use of Conservation of Resources (COR) theory, this paper explores the effects of technostress on 196 employees in childcare facilities in the Netherlands. Specifically, it investigates its effects on well-being and performance and the potential moderating role of social support. When analysing the role of social support, this paper contributes to the already available literature by making a distinction between the source of social support, namely supervisor and co-worker support. Results reveal that technostress has a negative impact on employee well-being, causing low work engagement and high emotional exhaustion, and it leads to a decrease in performance in terms of quality of care delivered. Moreover, well-being has a mediating role on these negative effects and can help reducing the impact of technostress. The hypotheses regarding the moderating role of social support could not be confirmed. Neither perceived supervisor support, nor co-worker support, gave significant results. As the complexity and ubiquity of ICTs increase, the present research identifies some critical issues that childcare facilities face and that must be addressed. It is important that the implementation and use of ICTs in the workplace is managed correctly in order to utilise those technologies in a more effective way.
The Elusive Coreceptors for the SARS-CoV-2 Spike Protein

Evidence suggests that the N-terminal domain (NTD) of the SARS-CoV-2 spike protein interacts with host coreceptors that participate in viral entry. Resolving the identity of coreceptors has important clinical implications as it may provide the basis for the development of antiviral drugs and vaccine candidates. The majority of characteristic mutations in variants of concern (VOCs) have occurred in the NTD and receptor binding domain (RBD). Unlike the RBD, mutations in the NTD have clustered in the most flexible parts of the spike protein. Many possible coreceptors have been proposed, including various sugars such as gangliosides, sialosides, and heparan sulfate. Protein coreceptors, including neuropilin-1 and leucine-rich repeat containing 15 (LRRC15), are also proposed coreceptors that engage the NTD.
Physiological indexes, psychological resilience, sensory functions, and sleep quality on the cognitive function of older adults with pre-frailty: a predictive study

Population ageing has increased the prevalence of prefrailty comorbid with cognitive impairment among older adults. However, few studies have explored the risk factors common to both prefrailty and cognitive impairment. This study determined the predictive accuracy of demographic characteristics, physiological indexes, psychological resilience, sensory function, and sleep quality on the cognitive function of older adults with prefrailty. In this cross-sectional study, the physiological indexes, psychological resilience, sensory function, sleep quality, and cognitive function of 167 community-dwelling older adults with prefrailty recruited through purposive sampling were measured. SPSS software was used for data coding and compilation. Data analysis involved the use of descriptive statistics, the independent samples t test, the chi-square test, and logistic regression. Overall, in cognitive function, there was no difference in gender but were in age, were incapable of text messaging, had a greater number of chronic diseases, were less able to perform activities of daily living, had low psychological resilience, and had depressive tendencies. In addition, Text messaging capability and depression status can all predict the cognitive impairment state of prefrail older elderly. Physiological indexes, psychological resilience, sensory function, and sleep quality can affect cognitive function in older adults with prefrailty. Meanwhile, depressive tendencies and the inability to send text messages on a mobile device constituted critical predictors of cognitive function in the participants.

Among the components of spirituality, self-awareness and spiritual activities alone are able to explain 12.53% and 2.46% of the variance of social Well-being , respectively (P<0.05). Conclusion: Based on the results of mindfulness skills training, strengthening social identity and spirituality-oriented programs, increase the level of social well-being of students.
Sounds, words

When listening to the human voice, listeners are able to perceive speaker-related information, for example the speaker’s gender. Previous research has revealed that the perception of voice gender is determined by two anatomically related vocal characteristics that vary with speaker size and hormone levels: the average fundamental frequency (F0), related to the glottal pulse rate, and perceived as the vocal pitch, and the formant frequencies, related to vocal tract length (VTL), described as the voice timbre. It has been shown that speaker identification and discrimination are influenced by linguistic processing, and especially the familiarity with the spoken language facilitates voice perception. However, if this effect arises at the phoneme or word level is unclear, as well as how this influences the perception and use of certain vocal parameters, such as F0 and VTL, for speaker discrimination or identification across listening conditions. Here, we studied the effects of lexical and phonological processing on the weighting of F0 and VTL on perceived voice gender categorization in normal-hearing adult listeners by manipulating the lexical status and recording direction, and F0 and VTL properties of female reference voices. Listeners gave significantly more weight on F0 and VTL when listening to words and nonwords compared to time-reversed nonwords. This indicates that phonological processing enhances the perceptual weighting of F0 and VTL for perceived voice gender categorisation. The interplay between linguistic and perceptual processes are discussed as well as methodological considerations when phonological processing are impaired and perception F0 and VTL are limited.
Contactless measurement of bulk lifetime and surface recombination velocity in silicon wafers

A method based on two phase shift measurements at two different modulation frequencies is proposed to determine simultaneously the actual bulk lifetime τb and the surface recombination velocity S in silicon wafers. Such a determination works, irrespectively, of the physical state of the surface or the passivation level, and is based on a microwave contactless technique, which allows mapping of τb and S with a spatial resolution of 50 μm.
