TECHNICAL NOTE A COLLOCATION METHOD WITH MODIFIED EQUILIBRIUM ON LINE METHOD FOR IMPOSITION OF NEUMANN AND ROBIN BOUNDARY CONDITIONS IN ACOUSTICS

A collocation method with the modified equilibrium on line method (ELM) for imposition of Neumann and Robin boundary conditions is presented for solving the two-dimensional acoustical problems. In the modified ELM, the governing equations are integrated over the lines on the Neumann (Robin) boundary instead of the Neumann (Robin) boundary condition equations. In other words, integration domains are straight lines for nodes located on the Neumann boundary. Numerical examples of two-dimensional acoustical problems are presented to demonstrate the stability, accuracy and convergence of the proposed method.
Solving #SAT Using Extension Rules

SAT problem is the extension of SAT problem. It involves counting models of a given set of proposition formulae. By using the inverse of resolution and the inclusion-exclusion principle to circumvent the problem of space complexity, this paper proposes a framework for both model counting and weighted model counting. It suggests a complementary method for current model counting methods. These methods are proved to be sound and complete. A model counting system, namely JLU-ERWMC, is built based on these methods. JLU-ERWMC outperforms the most efficient model counting methods in some cases.
Emergence of Japanese encephalitis in nonendemic regions of India: a public health concern?

The eve of 3 November 2022 witnessed the first case in about 3 years of the viral-borne disease Japanese encephalitis (JE) in the city of Pune, a nonendemic A region for the virus. A 4-year-old boy from the Wadgaonsheri area was admitted to the Pediatric ICU at Sassoon General Hospital with complaints of fever, convulsions, spastic paralysis, and altered sensorium. The child received treatment with little effect and was kept on ventilator support for 9 days. Blood and cerebrospinal fluid samples were sent for scrutinization to theNational Institute of Virology (NIV), Pune. Considering suspicions of an infectious pathology, the sera of seven household members, 16 nearby residents, 18 dogs, and pigs were also sampled and reported. The samples tested positive for JE on 29 November 2022. This raises concerns for a potential outbreak when considering the geographical, climatic, and sociocultural conditions of the population in the area.
Physiological Insights from Doppler Flow Patterns

Intraoperative echocardiography is traditionally viewed as a means to ascertain the adequacy of repair following congenital heart operations. Physiological assessment is traditionally limited to gross assessment of systolic ventricular function, right ventricular systolic pressures and identification of valvular regurgitation and measurement of flow gradients across outflow tracts. Transesophageal echocardiography is a window to a wealth of physiological information that needs to be systematically exploited. Doppler flow patterns across the pulmonary veins are influenced by rhythm, respiration, left atrial compliance, state of the mitral valve and left ventricular systolic and diastolic function. In the presence of an atrial septal defect (ASD), the pulmonary flow the left to right shunt influences flow patterns in the pulmonary veins and which in turn is determined by relative compliance of the right vs the left ventricle. The preoperative pulmonary blood flow patterns described by the authors in the paper in this journal are consistent with a substantial left to right flow across the ASD.1 Two distinct preoperative flow patterns were seen. The small sample size does not allow further analysis. It is conceivable that there are important distinctions between the commonly seen pattern of indistinct systolic-diastolic waves and the less common pattern of a single systolic peak. The difference could be the result of different shunt size, age, and relative ventricular compliance and should perhaps be investigated in a larger series. The changes in flow patterns after closure of the ASD is also of potential value. Following closure of ASD in adults a small proportion can develop substantial elevation in pulmonary venous pressure and this may result in pulmonary edema in a small minority.2,3 This is particularly dramatic following catheter-based closure of ASD in the older patient EDITORIAL
Hydroxyapatite Thin Films of Marine Origin as Sustainable Candidates for Dental Implants

Novel biomaterials with promising bone regeneration potential, derived from rich, renewable, and cheap sources, are reported. Thus, thin films were synthesized from marine-derived (i.e., from fish bones and seashells) hydroxyapatite (MdHA) by pulsed laser deposition (PLD) technique. Besides the physical–chemical and mechanical investigations, the deposited thin films were also evaluated in vitro using dedicated cytocompatibility and antimicrobial assays. The morphological examination of MdHA films revealed the fabrication of rough surfaces, which were shown to favor good cell adhesion, and furthermore could foster the in-situ anchorage of implants. The strong hydrophilic behavior of the thin films was evidenced by contact angle (CA) measurements, with values in the range of 15–18°. The inferred bonding strength adherence values were superior (i.e., ~49 MPa) to the threshold established by ISO regulation for high-load implant coatings. After immersion in biological fluids, the growth of an apatite-based layer was noted, which indicated the good mineralization capacity of the MdHA films. All PLD films exhibited low cytotoxicity on osteoblast, fibroblast, and epithelial cells. Moreover, a persistent protective effect against bacterial and fungal colonization (i.e., 1- to 3-log reduction of E. coli, E. faecalis, and C. albicans growth) was demonstrated after 48 h of incubation, with respect to the Ti control. The good cytocompatibility and effective antimicrobial activity, along with the reduced fabrication costs from sustainable sources (available in large quantities), should, therefore, recommend the MdHA materials proposed herein as innovative and viable solutions for the development of novel coatings for metallic dental implants.
Optimal Heart Rate May Improve Systolic and Diastolic Function in Patients with Fontan Circulation

(1) Background: The optimal heart rate, at which the E-wave and A-wave stand adjacent without any overlaps in the Doppler transmitral flow echocardiography, is associated with maximum cardiac output and favorable clinical outcomes in adult patients with systolic heart failure. However, the clinical implication of the echocardiographic overlap length in patients with Fontan circulation remains unknown. We investigated the relationship between heart rate (HR) and hemodynamics in Fontan surgery patients with and without beta-blockers. (2) Methods and Results: A total of 26 patients (median age 1.8 years, 13 males) were enrolled. At baseline, the plasma N-terminal pro-B-type natriuretic peptide was 2439 ± 3483 pg/mL, the fraction area change was 33.5 ± 11.4%, the cardiac index was 3.55 ± 0.90 L/min/m2, and the overlap length was 45.2 ± 59.0 msec. Overlap length was importantly decreased after the one-year follow-up (7.60 ± 78.57 msec, p = 0.0069). Positive correlations were noted between the overlap length and A-wave and E/A ratio (p = 0.0021 and p = 0.0046, respectively). Ventricular end-diastolic pressure was significantly correlated with the overlap length in non-beta-blocker patients (p = 0.0483). (3) Conclusion: Overlap length may reflect the status of ventricular dysfunction. Hemodynamic preservation at lower HR could be critical for cardiac reverse remodeling.

Identification and Evolution of Soil Organic Carbon Density Caused by Coastal Rapid Siltation Based on Imaging Spectroscopy

This article aimed to investigate the feasibility of using imaging spectroscopy (IS) to predict soil organic carbon density (SOCD) either directly or indirectly through soil organic carbon (SOC). Three methods, partial least square regression, support vector machine (SVM), and random forest, were utilized to calibrate the models and map the SOCD. The results showed that direct prediction was better than indirect prediction and the best model SVM had high R2 of 0.94 and 0.93 for calibration and validation, respectively. The measured SOCD was mainly concentrated in the surface soil layer from 0 to 40 cm, and the deeper layer tended to be gentle. The continuous depth variation trend of SOCD in the topsoil (0–40 cm) was relatively close to the measured values, while in the deeper layers (below 40 cm), it was much higher than the measured values. This article also found that the best fitting function of measured SOC stocks over time varied from linear to power and then to logarithmic with increasing depth, indicating less efficient accumulation of SOC in deep soil compared to topsoil, resulting in an overall decrease in SOC accumulation rate across soil depth. The best temporal functions for the predicted values differed from the measured values at each depth, but the changing trends of the three functions were basically consistent. It suggests that IS technology has the potential to quantitatively reveal the process of coastal soil evolution and offers a new insight for the rapid monitoring of soil property changes.
The MYB transcription factor RcMYB1 plays a central role in rose anthocyanin biosynthesis

Abstract Rose (Rosa hybrida) is one of most famous ornamental plants in the world, and its commodity value largely depends on its flower color. However, the regulatory mechanism underlying rose flower color is still unclear. In this study, we found that a key R2R3-MYB transcription factor, RcMYB1, plays a central role in rose anthocyanin biosynthesis. Overexpression of RcMYB1 significantly promoted anthocyanin accumulation in both white rose petals and tobacco leaves. In 35S:RcMYB1 transgenic lines, a significant accumulation of anthocyanins occurred in leaves and petioles. We further identified two MBW complexes (RcMYB1-RcBHLH42-RcTTG1; RcMYB1-RcEGL1-RcTTG1) associated with anthocyanin accumulation. Yeast one-hybrid and luciferase assays showed that RcMYB1 could active its own gene promoter and those of other EBGs (early anthocyanin biosynthesis genes) and LBGs (late anthocyanin biosynthesis genes). In addition, both of the MBW complexes enhanced the transcriptional activity of RcMYB1 and LBGs. Interestingly, our results also indicate that RcMYB1 is involved in the metabolic regulation of carotenoids and volatile aroma. In summary, we found that RcMYB1 widely participates in the transcriptional regulation of ABGs (anthocyanin biosynthesis genes), indicative of its central role in the regulation of anthocyanin accumulation in rose. Our results provide a theoretical basis for the further improvement of the flower color trait in rose by breeding or genetic modification.
Nutritional Status and Its Detection in Patients with Inflammatory Bowel Diseases

Malnutrition is an important issue in patients with inflammatory bowel diseases (IBDs) including Crohn’s disease (CD) and ulcerative colitis (UC). It is caused by altered digestion and absorption within the small bowel, inadequate food intake, and drug–nutrient interactions in patients. Malnutrition is an essential problem because it is related to an increased risk of infections and poor prognosis in patients. It is known that malnutrition is also related to an increased risk of postsurgery complications in IBD patients. Basic nutritional screening involves anthropometric parameters with body mass index (BMI) and others (fat mass, waist-to-hip ratio, muscle strength), medical history concerning weight loss, and biochemical parameters (including the Prognostic Nutritional Index). Besides standard nutritional screening tools, including the Subjective Global Assessment (SGA), Nutritional Risk Score 2002 (NRS 2002), and Malnutrition Universal Screening Tool (MUST), specific nutritional screening tools are used in IBD patients, such as the Saskatchewan Inflammatory Bowel Disease–Nutrition Risk Tool (SaskIBD-NR Tool and IBD-specific Nutritional Screening Tool). There is a higher risk of nutrient deficiencies (including iron, zinc, magnesium) and vitamin deficiencies (including folic acid, vitamin B12 and D) in IBD patients. Therefore, regular evaluation of nutritional status is important in IBD patients because many of them are undernourished. An association between plasma ghrelin and leptin and nutritional status in IBD patients has been observed. According to some authors, anti-tumor necrosis factor (anti-TNFα) therapy (infliximab) can improve nutritional status in IBD patients. On the other hand, improvement in nutritional status may increase the response rate to infliximab therapy in CD patients. Optimization of nutritional parameters is necessary to improve results of conservative and surgical treatment and to prevent postoperative complications in patients with IBDs. This review presents basic nutritional screening tools, anthropometric and laboratory parameters, dietary risk factors for IBDs, common nutrient deficiencies, associations between anti-TNFα therapy and nutritional status, selected features regarding the influence of nutritional status, and surgical outcome in IBD patients.
A Sensor-Based Modified FMD Method to Identify Fault Feature for Mechanical Fault Diagnosis of Ship-Borne Antennae

It is necessary to perform condition monitoring and fault identification on ship-borne antennae to ensure navigation safety. However, timely fault identification of key parts in a complicated drivetrain of the ship-borne antenna is still a challenging task since fault features are usually modulated and inevitably submerged by heavy noise. Therefore, a new adaptive feature extraction method based on Feature Mode Decomposition (FMD) is proposed in this paper for diagnostic purpose. First, scale transform is applied on the spectrum of the monitoring signal to determine the parameters of FMD, including the number of FIR filters, the location of each filter and the order of the filter bank. Second, a modified feature mode decomposition (MFMD) algorithm is proposed to adaptively extract mono-component modes and combine similar modes for weak feature enhancement. Finally, the combined modes are analyzed for mechanical fault identification based on Hilbert demodulation. Two application cases show that the proposed method owns superior performance during feature extraction, compared with the traditional methods.
A 2-D wavelet decomposition-based bag-of-visual-words model for land-use scene classification

Previous works about spatial information incorporation into a traditional bag-of-visual-words (BOVW) model mainly consider the spatial arrangement of an image, ignoring the rich textural information in land-use remote-sensing images. Hence, this article presents a 2-D wavelet decomposition (WD)-based BOVW model for land-use scene classification, since the 2-D wavelet decomposition method does well not only in textural feature extraction, but also in the multi-resolution representation of an image, which is favourable for the use of both spatial arrangement and textural information in land-use images. The proposed method exploits the textural structures of an image with colour information transformed into greyscale. Moreover, it works first by decomposing the greyscale image into different sub-images using 2-D discrete wavelet transform (DWT) and then by extracting local features of the greyscale image and all the decomposed images with dense regions in which a given image is evenly sampled by a regular grid with a specified grid space. After that, the method generates the corresponding visual vocabularies and computes histograms of visual word occurrences of local features found in each former image. Specifically, the soft-assignment or multi-assignment (MA) technique is employed, accounting for the impact of clustering on visual vocabulary creation that two similar image patches may be clustered into different clusters when increasing the size of visual vocabulary. The proposed method is evaluated on a ground truth image dataset of 21 land-use classes manually extracted from high-resolution remote-sensing images. Experimental results demonstrate that the proposed method significantly outperforms previous methods, such as the traditional BOVW model, the spatial pyramid representation-based BOVW method, the multi-resolution representation-based BOVW method, and so on, and even exceeds the best result obtained from the creator of the land-use dataset. Therefore, the proposed approach is very suitable for land-use scene classification tasks.
Convection-enhanced delivery of immunomodulatory therapy for high-grade glioma

Abstract The prognosis for glioblastoma has remained poor despite multimodal standard of care treatment, including temozolomide, radiation, and surgical resection. Further, the addition of immunotherapies, while promising in a number of other solid tumors, has overwhelmingly failed in the treatment of gliomas, in part due to the immunosuppressive microenvironment and poor drug penetrance to the brain. Local delivery of immunomodulatory therapies circumvents some of these challenges and has led to long-term remission in select patients. Many of these approaches utilize convection-enhanced delivery (CED) for immunological drug delivery, allowing high doses to be delivered directly to the brain parenchyma, avoiding systemic toxicity. Here, we review the literature encompassing immunotherapies delivered via CED—from preclinical model systems to clinical trials—and explore how their unique combination elicits an antitumor response by the immune system, decreases toxicity, and improves survival among select high-grade glioma patients.
A Double-Layer Metal-Only Huygens’ Metasurface Transmitarray

A dual-layer metal-only Huygens’ unit is presented, which consists of double antisymmetric multislot structures without relying on expensive dielectric substrates to achieve a complete 360° phase and high transmission amplitude (−2 dB). Also, the design strategy incorporates extra magnetic resonance, enriches the Huygens resonance, and allows more degrees of freedom to exploit the second harmonic for center frequency multiplication. In order to verify the design scheme, an 18 × 18 transmitarray prototype is created by laser engraving, which consists of two thin metal sheets with a length of 360 mm. The measurement results show a maximum gain of 25 dB, an aperture efficiency of 51.9%, and a 3 dB bandwidth of 10.1%. As a proof of concept, another frequency multiplication design is verified through full-wave simulations to achieve a maximum gain of 26.2 dB at 11.9 GHz under the illumination of a standard pyramid horn with a center frequency of 5.8 GHz.
Potential etiological factors in frontal fibrosing alopecia

Frontal fibrosing alopecia is a variant of lichen planus, leading to per - manent hair loss from the frontal hairline. It occurs mainly in postme - nopausal women, however, the role of hormonal factors in the pathoge - nesis of this type of alopecia has not been determined. The coexistence of frontal fibrosing alopecia and autoimmune diseases is observed, e.g., hypothyroidism, rheumatoid arthritis, vitiligo, polymyositis, systemic lupus erythematosus and discoid lupus erythematosus. Considering the possible role of genetic factors, research is underway to identify human leukocyte antigen (HLA) polymorphisms. One of the most stu - died factors is sunscreen, widely used in cosmetic products. The data available so far in this regard are controversial. Factors raising signi - ficant doubts include: the retrospective nature of the research, basing the collected data on the self-assessment of respondents and the lack of specification of the ingredients of these products. In the light of current data, sunscreen components cannot be considered as a factor playing a role in the pathogenesis of frontal fibrosing alopecia. Overestimation of the role of sunscreens in hair loss could lead to unjustified avoidance of their use and contribute to increased incidence of skin cancer.

ALDH2 rs671 Polymorphism Likely a Risk Factor for Hemorrhagic Stroke: A Hospital-Based Study

Background Hypertension is the main risk factor for hemorrhagic stroke. Aldehyde dehydrogenase 2 (ALDH2) may inhibit the occurrence of hypertension by anti-oxidative stress and vascular dilation. The purpose was to investigate the relationship of ALDH2 polymorphisms with hemorrhagic stroke in Hakka Chinese. Methods A total of 329 patients with hemorrhagic stroke and 515 controls were enrolled, and medical records (smoking and drinking history, hypertension, and diabetes) were collected. The genotypes of ALDH2 rs671 of the two groups were detected and analyzed. Results The proportion of the ALDH2 rs671 G/G, G/A, and A/A genotype in patients with hemorrhagic stroke was 55.9%, 37.4%, and 6.7%, respectively, while those were 65.0%, 30.7%, and 4.3% in controls, respectively. There was statistically significant difference in ALDH2 rs671 genotypes distribution (P=0.021) and alleles distribution (P=0.005) between patients and controls. Among hemorrhagic stroke patients, no statistically significant differences were observed between patients with ALDH2 different genotypes. Logistic regression analysis showed that there was significantly high risk of hemorrhagic stroke in men (male vs female: adjusted OR 1.711, 95% CI 1.154–2.538, P=0.008), the presence of hypertension (with vs without hypertension: adjusted OR 16.095, 95% CI 10.958–23.641, P<0.001), and the presence of ALDH2 rs671 G/A genotype (G/A vs G/G: adjusted OR 1.679, 95% CI 1.151–2.450, P=0.007) or A/A genotype (A/A vs G/G: adjusted OR 2.516, 95% CI 1.132–5.591, P=0.024). Conclusion ALDH2 rs671 polymorphism likely a risk factor for hemorrhagic stroke.
