Surface enhancement Raman spectroscopy and density functional theory study of silver nanoparticles synthetized with <scp>d</scp>‐glucose

Abstract The role of α‐ and β‐ d ‐glucose, and d ‐gluconate anion, acting as capping agent, on silver nanoparticles (AgNPs) was evaluated using both Raman and density functional theory studies. The particles were synthetized employing glucose, as reducing and blocking agent, in alkaline conditions. Capping agents were characterized through surface enhancement Raman spectroscopy together with modeling performed using silver clusters. Several geometries were optimized, and its energies and wavenumbers were calculated for each of them. Vibration normal modes from d ‐glucose isomers and d ‐gluconate were obtained and compared with those reported in bibliography, showing a satisfactory correlation. Comparison between experimental and calculated frequencies reveals a preference for d ‐gluconate anion acting as capping agent under the necessary presence of d ‐glucose on the surface of the AgNPs. The study of energies shows a greater affinity of d ‐gluconate for the silver atoms (above −1.3 eV for both geometries) than for other configurations of the glucose molecule (about −0.66 eV in the case of α‐ d ‐glucose).

Maximum Entropy Models, Dynamic Games, and Robust Output Feedback Control for Nonlinear Systems

In this paper, we develop a framework for designing controllers for general, partially observed discrete-time nonlinear systems which are robust with respect to uncertainties (disturbances). A general deterministic model for uncertainties is introduced, leading to a dynamic game formulation of the robust control problem. This problem is solved using an appropriate information state. We derive a partially observed nonlinear stochastic model as the maximum entropy stochastic model for the nonlinear system. A risk-sensitive stochastic control problem is formulated and solved for this partially observed stochastic model. The two problems are related using small noise limits. These small noise asymptotics are for the first time justified as the appropriate randomization, using time asymptotics of the Lagrange multipliers involved in the maximum entropy model construction. Thus for the first time a complete unification of deterministic and randomized uncertainty models is achieved. Various interpretations, consequences and applications of this unification are explained and discussed

Table_3_Early-life stress and dietary fatty acids impact the brain lipid/oxylipin profile into adulthood, basally and in response to LPS.xlsx

&lt;p&gt;Brain lipid dysregulation is a hallmark of depression and Alzheimer’s disease, also marked by chronic inflammation. Early-life stress (ELS) and dietary intake of polyunsaturated fatty acids (PUFAs) are risk factors for these pathologies and are known to impact inflammatory processes. However, if these early-life factors alter brain lipid homeostasis on the long-term and thereby contribute to this risk remains to be elucidated. We have recently shown that an early diet enriched in omega(ω)-3 PUFAs protected against the long-term negative effects of ELS on cognition and neuroinflammation. Here, we aim to understand if modulation of brain lipid and oxylipin profiles contributes to the detrimental effects of ELS and the protective ones of the diet. We therefore studied if and how ELS and early dietary PUFAs modulate the brain lipid and oxylipin profile, basally as well as in response to an inflammatory challenge, to unmask possible latent effects. Male mice were exposed to ELS via the limited bedding and nesting paradigm, received an early diet with high or low ω6/ω3 ratio (HRD and LRD) and were injected with saline or lipopolysaccharide (LPS) in adulthood. Twenty-four hours later plasma cytokines (Multiplex) and hypothalamic lipids and oxylipins (liquid chromatography tandem mass spectrometry) were measured. ELS exacerbated the LPS-induced increase in IL-6, CXCL1 and CCL2. Both ELS and diet affected the lipid/oxylipin profile long-term. For example, ELS increased diacylglycerol and LRD reduced triacylglycerol, free fatty acids and ceramides. Importantly, the ELS-induced alterations were strongly influenced by the early diet. For example, the ELS-induced decrease in eicosapentaenoic acid was reversed when fed LRD. Similarly, the majority of the LPS-induced alterations were distinct for control and ELS exposed mice and unique for mice fed with LRD or HRD. LPS decreased ceramides and lysophosphotidylcholine, increased hexosylceramides and prostaglandin E&lt;sub&gt;2&lt;/sub&gt;, reduced triacylglycerol species and ω6-derived oxylipins only in mice fed LRD and ELS reduced the LPS-induced increase in phosphatidylcholine. These data give further insights into the alterations in brain lipids and oxylipins that might contribute to the detrimental effects of ELS, to the protective ones of LRD and the possible early-origin of brain lipid dyshomeostasis characterizing ELS-related psychopathologies.&lt;/p&gt;

Ternary surface complex: coadsorption of Cu(II), Zn(II), Cd(II) and nitrilotris(methylenephosphonic) acid onto boehmite

This work studies the effect of NTMP (nitrilotris(methylenephosphonic acid)) on the adsorption of Cu(II), Zn(II), and Cd(II) onto boehmite in the pH range 5-9.5. The data were analyzed using the 2-pK constant capacitance model (CCM) assuming ternary surface complex formation. Under stoichiometric conditions, NTMP is more effective for removing Cu(II) than Zn(II) from solution and the contribution of ternary surface complexes are important to model the adsorption of both metals. Under nonstoichiometric conditions and high surface loading with a Me(II)/NTMP ratio of 1:5, Cu(II) and Zn(II) adsorption is significantly suppressed. In the case of Cd(II) the free metal adsorption is the most dominant species.

Automatic segmentation and identification of solitary pulmonary nodules on follow-up CT scans based on local intensity structure analysis and non-rigid image registration

This paper presents a novel method that can automatically segment solitary pulmonary nodule (SPN) and match such segmented SPNs on follow-up thoracic CT scans. Due to the clinical importance, a physician needs to find SPNs on chest CT and observe its progress over time in order to diagnose whether it is benign or malignant, or to observe the effect of chemotherapy for malignant ones using follow-up data. However, the enormous amount of CT images makes large burden tasks to a physician. In order to lighten this burden, we developed a method for automatic segmentation and assisting observation of SPNs in follow-up CT scans. The SPNs on input 3D thoracic CT scan are segmented based on local intensity structure analysis and the information of pulmonary blood vessels. To compensate lung deformation, we co-register follow-up CT scans based on an affine and a non-rigid registration. Finally, the matches of detected nodules are found from registered CT scans based on a similarity measurement calculation. We applied these methods to three patients including 14 thoracic CT scans. Our segmentation method detected 96.7% of SPNs from the whole images, and the nodule matching method found 83.3% correspondences from segmented SPNs. The results also show our matching method is robust to the growth of SPN, including integration/separation and appearance/disappearance. These confirmed our method is feasible for segmenting and identifying SPNs on follow-up CT scans.

Service with a smile: A source of emotional exhaustion or performance incentive in call‐centre employees

Abstract This study examines the relationships between emotional labour (surface acting, deep acting, and natural expression of positive emotions) and emotional exhaustion and service performance among 215 call centre employees. Of the hypotheses concerning the relation between the three emotional regulation strategies to emotional exhaustion and to service performance, only natural expression of positive emotion is significantly related to both consequences. Results also suggest that neuroticism moderates the link between deep acting and emotional exhaustion: employees with low levels of neuroticism seem more emotionally exhausted when they use deep acting.

Design, Simulation, and Prototyping of Single Composite Leaf Spring for Light Weight Vehicle

Reducing weight while increasing or maintaining strength of products is getting to be highly important research issue in this modern world. Composite materials are one of the material families which are attracting researchers and being solutions of such issue. In this project reducing weight of vehicles and increasing or maintaining the strength of their spare parts is considered. As leaf spring contributes considerable amount of weight to the vehicle and needs to be strong enough, a single E-glass/Epoxy leaf spring is designed and simulated following the design rules of the composite materials considering static loading only. The constant cross section design of leaf springs is employed to take advantages of ease of design analysis and its manufacturing process. And it is shown that the resulting design and simulation stresses are much below the strength properties of the material, satisfying the maximum stress failure criterion. The designed composite leaf spring has also achieved its acceptable fatigue life. This particular design is made specifically for light weight three wheeler vehicles. Its prototype is also produced using hand lay-up method.

Semi-Supervised Image-Based Narrative Extraction: A Case Study with Historical Photographic Records

This paper presents a semi-supervised approach to extracting narratives from historical photographic records using an adaptation of the narrative maps algorithm. We extend the original unsupervised text-based method to work with image data, leveraging deep learning techniques for visual feature extraction and similarity computation. Our method is applied to the ROGER dataset, a collection of photographs from the 1928 Sacambaya Expedition in Bolivia captured by Robert Gerstmann. We compare our algorithmically extracted visual narratives with expert-curated timelines of varying lengths (5 to 30 images) to evaluate the effectiveness of our approach. In particular, we use the Dynamic Time Warping (DTW) algorithm to match the extracted narratives with the expert-curated baseline. In addition, we asked an expert on the topic to qualitatively evaluate a representative example of the resulting narratives. Our findings show that the narrative maps approach generally outperforms random sampling for longer timelines (10+ images, p &lt; 0.05), with expert evaluation confirming the historical accuracy and coherence of the extracted narratives. This research contributes to the field of computational analysis of visual cultural heritage, offering new tools for historians, archivists, and digital humanities scholars to explore and understand large-scale image collections. The method's ability to generate meaningful narratives from visual data opens up new possibilities for the study and interpretation of historical events through photographic evidence.

Role of echocardiography in the diagnosis and evaluation of severity of mitral and tricuspid stenosis.

The presence, severity, and hemodynamic consequences of mitral and tricuspid stenosis can be determined by echocardiographic techniques. In mitral stenosis two-dimensional echocardiographic imaging allows definition of leaflet anatomy and dynamics, subvalvular disease, ventricular function, and involvement of other valves. Spectral and color Doppler echocardiographic techniques permit accurate measurement of transvalvular gradient, determination of functional orifice area, evaluation of associated valvular regurgitation, and assessment of pulmonary artery pressures. These approaches are of recognized clinical value, and they provide additional diagnostic information that is unavailable from clinical assessment alone in a significant number of patients. Compared with available invasive diagnostic standards of reference, echocardiographic data have been found to be comparable in accuracy. In tricuspid stenosis echocardiographic imaging and Doppler techniques provide an assessment of valve morphology and function that should be similarly useful in clinical management decisions, although rigorous comparative studies have not been performed. Currently, carefully done echocardiographic studies are a definitive means of establishing the presence and significance of mitral stenosis and tricuspid stenosis, thereby obviating the need for invasive evaluation in many patients, reducing risk, and potentially decreasing the cost of diagnostic assessment.

Comparison of Transvalvular Aortic Mean Gradients Obtained by Intraprocedural Echocardiography and Invasive Measurement in Balloon and Self‐Expanding Transcatheter Valves

Background Concerns about discordance between echocardiographic and invasive mean gradients after transcatheter aortic valve replacement (TAVR) with balloon‐expandable valves (BEVs) versus self‐expanding valves (SEVs) exist. Methods and Results In a multicenter study, direct‐invasive and echocardiography‐derived transvalvular mean gradients obtained before and after TAVR were compared as well as post‐TAVR and discharge echocardiographic mean gradients in BEVs versus SEVs in 808 patients. Pre‐TAVR, there was good correlation ( R =0.614; P &lt;0.0001) between direct‐invasive and echocardiography‐derived mean gradients and weak correlation ( R =0.138; P &lt;0.0001) post‐TAVR. Compared with post‐TAVR echocardiographic mean gradients, both valves exhibit lower invasive and higher discharge echocardiographic mean gradients. Despite similar invasive mean gradients, a small BEV exhibits higher post‐TAVR and discharge echocardiographic mean gradients than a large BEV, whereas small and large SEVs exhibit similar post‐TAVR and discharge mean gradients. An ejection fraction &lt;50% ( P =0.028) and higher Society of Thoracic Surgeons predicted risk of mortality score ( P =0.007), but not invasive or echocardiographic mean gradient ≥10 mm Hg ( P =0.378 and P =0.341, respectively), nor discharge echocardiographic mean gradient ≥20 mm Hg ( P =0.393), were associated with increased 2‐year mortality. Conclusions Invasively measured and echocardiography‐derived transvalvular mean gradients correlate well in aortic stenosis but weakly post‐TAVR. Post‐TAVR, echocardiography overestimates transvalvular mean gradients compared with invasive measurements, and poor correlation suggests these modalities cannot be used interchangeably. Moreover, echocardiographic mean gradients are higher on discharge than post‐TAVR in all valves. Despite similar invasive mean gradients, a small BEV exhibits higher post‐TAVR and discharge echocardiographic mean gradients than a large BEV, whereas small and large SEVs exhibit similar post‐TAVR and discharge mean gradients. Immediately post‐TAVR, elevated echocardiographic‐derived mean gradients should be assessed with caution and compared with direct‐invasive mean gradients. A low ejection fraction and higher Society of Thoracic Surgeons score, but not elevated mean gradients, are associated with increased 2‐year mortality.

A Methodology for Applying Bar Code Technology to Aircraft Maintenance Unit Support Sections.

This study developed a methodology that decision makers can use as an aid to determine if bar code technology should be applied in Aircraft Maintenance Unit (AMU) Support Sections. The literature review revealed that the Logistics Applications of Automated Marking and Reading Symbols (LOGMARS) steering group recommended that bar code technology applications be aggressively pursued across the logistics spectrum due to the success of the LOGMARS test program. Since AMU support sections perform many functions similar to those that have already benefited form this technology as it applies to an AMU support sections. Worksheets were designed to help collect and analyze the necessary cost/benefit information so that decision makers will be able to properly assess the expected cost and benefits for a particular support section.

Elevated levels of IL-1β in Fanconi anaemia group A patients due to a constitutively active phosphoinositide 3-kinase-Akt pathway are capable of promoting tumour cell proliferation

FA (Fanconi anaemia) is a hereditary disease characterized by congenital malformations, progressive bone marrow failure and an extraordinary elevated predisposition to develop cancer. In the present manuscript we describe an anomalous high level of the proinflammatory cytokine IL-1β (interleukin-1β) present in the serum of FA patients. The elevated levels of IL-1β were completely reverted by transduction of a wild-type copy of the FancA cDNA into FA-A (FA group A) lymphocytes. Although the transcription factor NF-κB (nuclear factor-κB) is a well established regulator of IL-1β expression, our experiments did not show any proof of elevated NF-κB activity in FA-A cells. However, we found that the overexpression of IL-1β in FA-A cells is related to a constitutively activated PI3K (phosphoinositide 3-kinase)-Akt pathway in these cells. We provide evidence that the effect of Akt on IL-1β activation is mediated by the inhibition of GSK3β (glycogen synthase kinase 3β). Finally, our data indicate that the levels of IL-1β produced by FA-A lymphoblasts are enough to promote an activation of the cell cycle in primary glioblastoma progenitor cells. Together, these results demonstrate that the constitutive activation of the PI3K-Akt pathway in FA cells upregulates the expression of IL-1β through an NF-κB-independent mechanism and that this overproduction activates the proliferation of tumour cells.
