Risk Factors and Outcomes of Multidrug-Resistant Bacteria Infection in Infected Pancreatic Necrosis Patients

Objective The incidence of acute pancreatitis (AP) is increasing. Twenty percent of AP patients with developing necrotizing pancreatitis (NP), while ~40–70% of NP patients develop potentially fatal infectious complications. When patients are suspected or confirmed infected pancreatic necrosis (IPN), antibiotics should be administered timeously to control the infection, but long-term use of antibiotics can lead to multidrug-resistant bacteria (MDRB) infection and eventually to increased mortality. Our study aimed to determine the incidence of MDRB infection and evaluate the risk factors for MDRB infection in IPN patients. Methods Clinical data of IPN patients admitted to the general surgery department of Xuanwu Hospital of Capital Medical University between January 1, 2014, and December 31, 2021, were retrospectively analyzed. Results IPN patients (n = 267) were assigned to MDRB infection (n = 124) and non-MDRB infection (n = 143) groups. On admission, patients in the MDRB group had a higher modified computer tomography severity index (CTSI) score (P < 0.05), pancreatic necrosis degree, and PCT level (P < 0.05) than those in the non-MDRB group, and the prognosis of patients in MDRB group was poor. The most common gram-negative bacteria were Acinetobacter baumannii (n = 117), the most common gram-positive bacteria were Enterococcus faecium (n = 98), and the most common fungal infection was Candida albicans (n = 47). Multivariable analysis showed that complications of EPI (OR: 4.116, 95% CI: 1.381–12.271, P = 0.011), procalcitonin (PCT) level at admission (OR: 2.728, 95% CI: 1.502–4.954, P = 0.001), and degree of pancreatic necrosis (OR: 2.741, 95% CI: 1.109–6.775, P = 0.029) were independent risk factors for MDRB infection in IPN patients. Conclusion We identified common infectious strains and risk factors for MDRB infection in IPN patients.
Decreased Serum Uric Acid Level as an Indicator of Altered Oxidative Balance in Patients With Migraine

Introduction: Migraine is one of the most common neurological diseases. The pathophysiology of migraine has not yet been fully elucidated. There is increasing evidence supporting the relationship between oxidative stress and migraine. Method: This is a retrospective, cross-sectional and observational study. The patients were divided into two groups, episodic migraine and chronic migraine. Episodic migraine patients were divided into two subgroups, migraine with aura and migraine without aura. Serum Albumin, total bilirubin, uric acid levels, and migraine clinical findings were obtained from medical records. Results: A total of 181 participants, 88 patients and 93 controls, were included in the study. Serum albumin levels were lower in the patient group than in the control group, they did not reach statistical significance (p=0.082). There was no significant difference between the patient and control groups for total bilirubin levels (p=0.785). Serum uric acid levels in the patient group were found to be significantly lower than in the control group (p<0.001). Measured levels were similar in chronic and episodic migraine groups, and migraine with aura and migraine without aura subgroups. Conclusion: We thought this oxidative stress marker may be associated with the presence of migraine, but this is not significant for migraine subtypes and migraine progression.
Upper Limb Kinematics of Handwriting among Children with and without Developmental Coordination Disorder

Background: Children with developmental coordination disorder (DCD) often experience difficulties with handwriting legibility and speed. This study investigates the relationship between handwriting and upper limb kinematics to characterize movement patterns of children with DCD and typically developing (TD) children. Methods: 30 children with and without DCD matched for age, gender, and parent education were compared across handwriting abilities using a standardized handwriting assessment of both copied and dictated tasks (A-A Handwriting). The 3D motion capture system (Qualysis) was used to analyze upper limb kinematics and characterize movement patterns during handwriting and contrasted with written output. Results: Children with DCD wrote fewer legible letters in both copying and dictation. Children with DCD also showed poor automatization of key writing concepts. Atypical wrist postures were associated with reduced legibility for children with DCD (F (1,27) 4.71, p = 0.04, p-η2 = 0.15); whereas for TD children, better legibility was associated with greater variations in movement speed, particularly of the wrist (rho = −0.578, p < 0.05). Conclusion: Results reflect different movement parameters influencing handwriting in children with DCD. An improved understanding of the movement characteristics during handwriting of these children may assist intervention design.
High-Speed Particle Image Velocimetry and Force Measurements of Bio-Inspired Surfaces

To evaluate the influence of the velvet-like surface mimicking the structure on the suction side of barn owl wings on the flow field and on the aerodynamic performance of the wing, high-speed particle image velocimetry and time-resolved force measurements were performed. The Reynolds number was varied in the range of 40,000≤Rec≤120,000, and the range of the angles of attack was 0≤α≤6 deg for the particle image velocimetry measurements and −15≤α≤+20 deg for the force measurements. The flow over a clean-wing model whose geometry corresponds to that of the owl wing without any special adaptations was investigated as a reference case for the same Reynolds number and angle of attack range. This clean wing possesses a laminar separation bubble as the dominant flow feature. Two artificial surfaces were selected to mimic the natural surface concerning the length, density, and thickness of the filaments. The surfaces were able to reduce flow separation. Although this reduction of the separation region might have.
ROBUST ESTIMATES, RESIDUALS, AND OUTLIER DETECTION WITH MULTIRESPONSE DATA

SUMMARY The paper gives an overview of concepts and techniques pertaining to (i) the robust estimation of multivariate location and dispersion; (ii) the analysis of two types of multidimensional residuals-namely those that occur in the context of principal components analysis as well as the more familiar residuals associated with least squares fitting; and (iii) the detection of multiresponse outliers. The emphasis is on methods for informal exploratory analysis and the coverage is both a survey of existing techniques and an attempt to propose, tentatively, some new methodology which needs further investigation and development. Some examples of use of the methods are included.
Deep Learning-Based Speech Emotion Recognition Using Multi-Level Fusion of Concurrent Features

The detection and classification of emotional states in speech involves the analysis of audio signals and text transcriptions. There are complex relationships between the extracted features at different time intervals which ought to be analyzed to infer the emotions in speech. These relationships can be represented as spatial, temporal and semantic tendency features. In addition to emotional features that exist in each modality, the text modality consists of semantic and grammatical tendencies in the uttered sentences. Spatial and temporal features have been extracted sequentially in deep learning-based models using convolutional neural networks (CNN) followed by recurrent neural networks (RNN) which may not only be weak at the detection of the separate spatial-temporal feature representations but also the semantic tendencies in speech. In this paper, we propose a deep learning-based model named concurrent spatial-temporal and grammatical (CoSTGA) model that concurrently learns spatial, temporal and semantic representations in the local feature learning block (LFLB) which are fused as a latent vector to form an input to the global feature learning block (GFLB). We also investigate the performance of multi-level feature fusion compared to single-level fusion using the multi-level transformer encoder model (MLTED) that we also propose in this paper. The proposed CoSTGA model uses multi-level fusion first at the LFLB level where similar features (spatial or temporal) are separately extracted from a modality and secondly at the GFLB level where the spatial-temporal features are fused with the semantic tendency features. The proposed CoSTGA model uses a combination of dilated causal convolutions (DCC), bidirectional long short-term memory (BiLSTM), transformer encoders (TE), multi-head and self-attention mechanisms. Acoustic and lexical features were extracted from the interactive emotional dyadic motion capture (IEMOCAP) dataset. The proposed model achieves 75.50% and 75.82% of weighted and unweighted accuracy, 75.32% and 75.57% of recall and F1 score respectively. These results imply that concurrently learned spatial-temporal features with semantic tendencies learned in a multi-level approach improve the model’s effectiveness and robustness.
Air Pollution, Cardiovascular and Respiratory Admissions in Klang Valley, Malaysia - Finding the Effects

This study aims to determine the association and risk of daily fluctuations of air pollution parameters in Klang Valley, Malaysia, with cardiovascular and respiratory admissions. The data on admissions and air pollution concentrations were obtained from various government agencies in Malaysia. The associations were estimated using a time series analysis of Poisson regression. The effects for every 10μ/m3 increase in pollutants were reported as Relative Risk (RR). SO2 showed the highest association with immediate effects at lag 0 for all cardiovascular admissions followed by NO2. Gaseous pollutants of SO2 and NO2 showed a higher risk among elderly more than 60 years old. Immediate effects were found in both genders, with higher risks observed in males. NO2 continues to be suggestively associated with all respiratory admissions. Children less than 9 years old presented a higher risk of NO2 at various lag times with the highest value at lag0, followed by PM10. Stratified analysis showed an incremental risk of respiratory admissions for males exposed to NO2 compared to females. We found noteworthy associations for overall and age-specific admissions of cardiovascular and respiratory with the pollutants. Compared to particulates pollutant, gaseous pollutants showed a higher risk in both admissions.
Direct numerical simulation of flow and heat transfer in a turbine cascade with incoming wakes

Direct numerical simulations (DNS) of flow in a turbine cascade with heat transfer have been performed. The set-up of the simulations was chosen in close accordance with previous experiments. Three of the experimental situations were simulated: one without free-stream turbulence and two with periodically incoming wakes of different frequency and with different levels of background fluctuation. Hence, the calculations allow us to study the influence of impinging wakes and background fluctuations on the development of the boundary layers and the local Nusselt number along the surfaces of the heated blade. Along the suction side, the pressure gradient is first favourable and then turns adverse near the trailing edge and the boundary layer remains laminar for the case without free-stream turbulence with the Nusselt number showing the typical decay from the leading to the trailing edge. With periodic wakes and background turbulence, transition occurs when the pressure gradient turns adverse, but intermittency persists so that the boundary layer is not fully turbulent when the trailing edge is reached. In this region, the heat transfer is increased significantly by an amount comparable to that found in the experiments. In the pre-transitional region with favourable pressure gradient, the flow acceleration stretches the free-stream vortices, aligning their axis with the flow direction, thereby forming streamwise vortical structures. These increase the laminar heat transfer in this region by 20–30%, which is, however, much less than observed in the experiments. On the pressure side, the pressure gradient is favourable along the entire blade so that the boundary layer remains laminar. Here, the wakes, through their impingement, also generate streamwise vortical structures which, because of the low convection speed on this side, have a very long lifetime compared to the structures along the suction side. Also these structures increase the laminar heat transfer by about 30%, which for the case with the highest wake frequency is again much less than in the experiments. The simulated average level of fluctuations in the laminar parts of the boundary layers is comparable or even higher than that in the experiments so that it seems likely that a difference in the spectral contents causes the discrepancies. The wake turbulence entering the calculation domain corresponds to that in far wakes with relatively small-scale structures, whereas in the experiments the wakes most probably still carried some large-scale fluctuations of the size of the wake width, which have been found to be more effective in increasing laminar heat transfer.
Feedback control of travelling wave solutions of the complex Ginzburg–Landau equation

Through a linear stability analysis, we investigate the effectiveness of a noninvasive feedback control scheme in stabilizing travelling wave solutions, R eiKx+iωt, of the one-dimensional complex Ginzburg–Landau equation (CGLE) in the Benjamin–Feir unstable regime. The feedback control, a generalization of the time-delay method of Pyragas (1992 Phys. Lett. A 170 421), was proposed by Lu et al (1996 Phys. Rev. Lett. 76 3316) in the setting of nonlinear optics. It involves both spatial shifts, by the wavelength of the targeted travelling wave, and a time delay that coincides with the temporal period of the travelling wave. We derive a single necessary and sufficient stability criterion that determines whether a travelling wave is stable to all perturbation wavenumbers. This criterion has the benefit that it determines an optimal value for the time-delay feedback parameter. For various coefficients in the CGLE we use this algebraic stability criterion to numerically determine stable regions in the (K, ρ)-parameter plane, where ρ is the feedback parameter associated with the spatial translation. We find that the combination of the two feedbacks greatly enlarges the parameter regime where stabilization is possible, and that the stable regions take the form of stability tongues in the (K, ρ)-plane. We discuss possible resonance mechanisms that could account for the spacing with K of the stability tongues.
Developing MOFI on Transverse Wave to Explore Students’ Misconceptions Today: Utilizing Rasch Model Analysis

This research aimed to describe the diagnostic instrument validity from Multi-representation of Four-tier Instrument on Transverse Wave (MOFI-OTW), which is useful in exploring the misconceptions. The ADDIE (Analyzing, Designing, Developing, Implementing, and Evaluating) model has already been utilized as the research method. In the developing stage, item construction is in the form of multi-representation (statements, pictures, graphs, tables, and mathematical symbols). The sample consisted of 81 high school students aged 16-18 years (23 males called “Cung” and 58 females called “Nduk”) in East Java. Data validity, instrument reliability, and distribution of students' conceptions have been analyzed using the Rasch Model with MINISTEP 4.7. 0.0 software. Validity based on item dimensionality is valid. The reliability based on Cronbach Alpha (α) is good category, the value of item reliability is very good category, and person reliability is moderat category. Students’ conceptions are categorized as Sound Understanding (SU), Partial Understanding Positive (PUP), Partial Understanding Negative (PUN), No Understanding (NU), Misconception (MC), and No Coding (NC). The largest conception category is MC. Misconceptions are still found in the sub-concept of transverse wave in various representations. In conclusion, MOFI-OTW can be developed through the ADDIE model by utilizing the Rasch analysis and used to explore students' conceptions and misconceptions.
The role of non-local external resources and less-urban location in design processes – A study of the Danish fashion industry

ABSTRACT The fashion industry is heavily dependent on constant revitalization of the design of its products. Fashion products are on the one hand based on local cultural values and on the other hand a global business. Due to the need for new designs, the fashion industry is often associated with urban location and urban buzz. The geography of the industry is, however, more complex. Fashion firms are also located in less-urban areas competing on the same parameters as urban located firms, namely design. Based on a survey of 51 Danish firms in the fashion industry and 9 interviews with representatives of firms in the fashion industry, this paper explores the importance of use of external non-local resources in the design process in the fashion industry and further to what extent the importance of these resources differs between urban and less-urban located firms in Danish fashion industry.
Diffusion pathways of phosphorus atoms on silicon (001)

Using density-functional theory and a combination of growing string and dimer method transition state searches, we investigate the interaction of phosphorus atoms with the silicon (001) surface. We report reaction pathways for three technologically important processes: diffusion of phosphorus adatoms on the surface, incorporation of the phosphorus adatom into the surface, and diffusion of the incorporated phosphorus atom within the surface. These reactions have direct relevance to nanoscale lithographic schemes capable of positioning single phosphorus atoms on the silicon surface. Temperatures of activation for the various processes are calculated and, where possible, compared with experiment.

Transferable Resilience Practices: Communication and Resilience of U.S. Military Spouses during the Initial Stages of the COVID-19 Pandemic

ABSTRACT This study uses the communication theory of resilience as a sensitizing framework to explore how U.S. military spouses transferred resilience practices acquired during military deployment to early phases of the COVID-19 pandemic. Data from 27 in-depth interviews with U.S. military spouses showed that the military experience shaped participants’ appraisal of the pandemic and helped them to discursively enact resilience through previously developed practices. Six major themes emerged: (a) crafting normalcy through the military lifestyle and experience; (b) affirming identity through military anchors; (c) invoking military mantras as alternative logics; (d) foregrounding productive action through flexibility and planning; (e) maintaining communication networks through (i) technology, (ii) family and community support, and (iii) intentional communication with partner; and (f) downplaying negative feelings by generating positive emotions. Findings contribute to the communication theory of resilience by showing how individuals with a history of resilience can transfer already-built resilience practices from one context (deployment) to another (COVID-19).
Study of Investment Casting Process For 3D Printed Jewellery Design

Manufacturing processes are increasingly complex with the growing demands of advanced technology in the production processes, especially in the handicraft industry. The complex jewellery designs are complicated to be produced by hand, considering the international demand and dynamics in the jewellery industry. However, advanced production processes and 3D printers are changing the way jewellery designers and manufacturers work and making it easier to produce quality products with fewer production and labour input hours. This study examines the investment casting process of 3D printed design as an option for jewellery manufacturing. The research aims to access jewellery manufacturing processes and its technology application by using trending 3D printing as a rapid prototype. It used the design and production process of 'OneCent Africa' as a case study to describe the process in the investment casting of jewellery products. The investment casting was conducted by prototyping, and the lost wax jewellery casting stages using the vacuum casting machines and burnout oven, with the casting process monitored in parts. This research results led to a better understanding of the experimental casting outcomes and described the potential for the future technological development of jewellery businesses.
Radio Constraints on the Nature of BL Lacertae Objects and their Parent Population

5 GHz VLA observations of 17 BL Lac objects with bright radio cores at both high and low resolution are reported. Extended emission is detected around most objects. None of the sources observed at low resolution show evidence of giant halos on the scale of tens of arcmin. In general, the sources with the most luminous extended emission exhibit FR II characteristics in both morphology and polarization, and less luminous sources exhibit FR I characteristics. Thus, the parent population of the BL Lac objects contains both FR I and FR II radio sources. No BL Lac objects are found that clearly exhibit quasarlike polarization at milliarcsec resolution. This argues against the view that the more luminous BL Lac objects are simply an extension of the quasar/OVV population, or that most BL Lac objects are gravitationally microlensed images of distant quasars. Other properties are generally consistent with the view the BL Lac objects are normal radio galaxies whose jets make a small angle to the line of sight.
