We propose and numerically investigate a perfect ultra-narrowband absorber with an absorption bandwidth of only 1.82 nm and an absorption efficiency exceeding 95% in the visible region. We demonstrate that the perfect ultra-narrowband absorption is ascribed to the coupling effect induced by localized surface plasmon resonance. The influence of structural dimensions on the optical performance is also investigated, and the optimal structure is obtained with the extremely low reflectivity (0.001) of the resonance dip...

The attitude towards one's own imperfection strongly varies between individuals. Here, we investigated variations in error-related activity depending on two sub-traits of perfectionism, Personal Standard Perfectionism (PSP) and Evaluative Concern Perfectionism (ECP) in a large scale functional magnetic resonance imaging study (N = 75) using a digit-flanker task. Participants with higher PSP scores showed both more post-error slowing and more neural activity in the medial-frontal gyrus including anterior cingulate cortex after errors...

Serum carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is dysregulated in various malignant tumors and has been associated with tumor progression. However, the expression and regulatory mechanisms of serum CEACAM1 in gastrointestinal cancer are still unclear. The expression ratio of the CEACAM1-L and CEACAM1-S isoforms has seldom been investigated in gastrointestinal cancer. In this study, we intended to explore the expression and diagnostic value of CEACAM1 in gastrointestinal cancer. Serum CEACAM1 levels were measured by enzyme-linked immunosorbent assay...

Purpose: Reductions in articulatory working space and vocal intensity have been linked to intelligibility deficits in children with dysarthria due to cerebral palsy. However, few studies have examined the outcomes of behavioral treatments aimed at these underlying impairments or investigated which treatment cues might best facilitate improved intelligibility. This study assessed the effects of cues targeting clear speech (i.e., "Speak with your big mouth") and greater vocal intensity (i...

Purpose: The impact of clear speech or an increased vocal intensity on consonant spectra was investigated for speakers with mild dysarthria secondary to multiple sclerosis or Parkinson's disease and healthy controls. Method: Sentences were read in habitual, clear, and loud conditions. Spectral moment coefficients were obtained for word-initial and word-medial /s/, /ʃ/, /t/, and /k/. Global production differences among conditions were confirmed with measures of vocal intensity and articulation rate...

Acoustic Droplet Vaporization (ADV) has the potential to shorten treatment time of high intensity focused ultrasound (HIFU) while minimizing the possible effects of microbubbles along the propagation path. Distribution of the bubbles formed from the droplets during the treatment is the major factor shaping the therapeutic region. A numerical model was proposed to simulate the bubble area evolution during this treatment. Using a linear acoustic equation to describe the ultrasound field, a threshold range was defined that determines the amount of bubbles vaporized in the treated area...

The application of tetraethylammonium (TEA), a blocker of voltage-dependent potassium channels, can induce long-term potentiation in the synaptic systems CA3 - CA1 and mossy fibers - CA3 pyramidal cells of the hippocampus. In the mossy fibers the depolarization evoked by extracellular TEA induces a large amount of glutamate and also of zinc release. It is considered that zinc has a neuromodulatory role at the mossy fiber synapses, which can, at least in part, be due to the activation of presynaptic ATP-dependent potassium (KATP) channels...

Four models for the calculation of the IR spectrum of gas phase molecules and clus- ters from molecular dynamics simulations are presented with the aim to reduce the computational cost of the usual Fourier transform (FT) of the time correlation function of the dipole moment. These models are based on the VDOS, FT of time correlation function of velocities, and Atomic Polar Tensors (APT). The models differ from each other by the number of APTs inserted into the velocities correlation function. Excellent accuracy is achieved by the model adopting a weighted linear combination of a few se- lected APTs adapted for the rotation of the molecule (model D)...

Carbon dots (CDs) are covalently coupled to the polyacrylic acid (PAA) block of polystyrene-b-polyacrylic acid (PS-b-PAA). The produced amphiphilic PS-b-PAA-CD shows excellent solubility and micellar formation in selective solvents. Transmission electron microscopy study shows that the micelle of PS-b-PAA-CD in water (a PAA-selective solvent) has a strawberry-like shape with the CDs as patches on the PAA corona surface although that in toluene (a PS-selective solvent) has a reversed shape with the CDs in the core...

Reactions of 2-aryl cyclopropane dicarboxylates with naphthoquinones are reported. The key feature was the use of catalytic amounts of SnCl2, which acts as both electron donor and Lewis acid. By an in-situ umpolung of naphthoquinone the formerly electrophilic species is converted into a nucleophile that is able to trigger the ring-opening of the three-membered ring with formation of a new C-C bond. Treatment of these products with base under oxidative conditions resulted - by losing methyl formate - in cyclopentannulated products with fully conjugated π systems exhibiting intensive absorptions in the visible range...

BACKGROUND: Obsessive-compulsive disorder (OCD) is prevalent and without adequate treatment usually follows a chronic course. "High-intensity" cognitive-behaviour therapy (CBT) from a specialist therapist is current "best practice." However, access is difficult because of limited numbers of therapists and because of the disabling effects of OCD symptoms. There is a potential role for "low-intensity" interventions as part of a stepped care model. Low-intensity interventions (written or web-based materials with limited therapist support) can be provided remotely, which has the potential to increase access...

Breakthrough cancer Pain (BTcP) has a high prevalence in cancer population. Patients with BTcP reported relevant health care costs and poor quality of life. The study assessed the cost-effectiveness of the available Oral Fentanyl Formulations (OFFs) for BTcP in Italy. A decision-analytical model was developed to estimate costs and benefits associated with treatments, from the Italian NHS perspective. Expected reductions in pain intensity per BTcP episodes were translated into, percentage of BTcP reduction, resource use and Quality-Adjusted-Life-Years (QALYs)...

The objective of this pilot study was to compare the different ways of measuring salivary alpha-amylase (sAA, enzymatic vs. concentration) and to evaluate the influence that the different ways of reporting the results can have in sAA interpretation. For this purpose, sAA was measured by direct quantification and also by an enzymatic assay in three different naturalistic situations, a physical stressor (situation 1) and two mental stressors of different intensity (situations 2 and 3). The results were expressed in three different ways (without correction, multiplied by flow rate and divided by protein concentration)...

Climate change and species invasions interact in nature, disrupting biological communities. Based on this knowledge, we simultaneously assessed the effects of climate change on the native distribution of the Amazonian fish Colossoma macropomum as well as on its invasiveness across river basins of South America, using ecological niche modeling. We used six niche models within the ensemble forecast context to predict the geographical distribution of C. macropomum for the present time, 2050 and 2080. Given that this species has been continuously introduced into non-native South American basins by fish farming activities, we added the locations of C...

OBJECTIVES: Knee osteoarthritis (KOA) can be associated with local and central sensitization. As an indicator of the central gain, facilitated temporal summation of pain (TSP) has been found in KOA patients. This facilitation is predictive of the development of chronic postoperative pain after total knee arthroplasty (TKA). Other studies have suggested hypoesthesia/hypoalgesia to thermal stimuli as a feature in KOA. This study investigated associations between preoperative TSP, thermal sensitivity and radiological severity for the development of chronic postoperative pain after TKA...

OBJECTIVES: The pectoral nerves (Pecs) II block is a technique that places local anesthetic between the thoracic muscles to block the axillary and breast regions. This study aimed to compare the quality of perioperative analgesia and side effects of the Pecs II block under general anesthesia versus general anesthesia alone in immediate unilateral breast reconstruction with an implant and latissimus dorsi (LD) flap after modified radical mastectomy. METHODS: Sixty-four patients scheduled for immediate breast reconstruction after modified radical mastectomy were randomly allocated into the Pecs II block under general anesthesia group (Group P, n=32) or the general anesthesia alone group (Group G, n=32)...
