Stabilized finite element methods for time dependent convection-diffusion equations

STABILIZED FINITE ELEMENT METHODS FOR TIME DEPENDENT CONVECTION-DIFFUSION EQUATIONS In this thesis, enriched finite element methods are presented for both steady and unsteady convection diffusion equations. For the unsteady case, we follow the method of lines approach that consists of first discretizing in space and then use some time integrator to solve the resulting system of ordinary differential equation. Discretization in time is performed by the generalized Euler finite difference scheme, while for the space discretization the streamline upwind Petrov-Galerkin (SUPG), the Residual free bubble (RFB), the more recent multiscale (MS) and specific combination of RFB with MS (MIX) methods are considered. To apply the RFB and the MS methods, the steady local problem, which is as complicated as the original steady equation, should be solved in each element. That requirement makes these methods quite expensive especially for two dimensional problems. In order to overcome that drawback the pseudo approximation techniques, which employ only a few nodes in each element, are used. Next, for the unsteady problem a proper adaptation recipe, including these approximations combined with the generalized Euler time discretization, is described. For piecewise linear finite element discretization on triangular grid, the SUPG method is used. Then we derive an efficient stability parameter by examining the relation of the RFB and the SUPG methods. Stability and convergence analysis of the SUPG method applied to the unsteady problem is obtained by extending the Burman’s analysis techniques for the pure convection problem. We also suggest a novel operator splitting strategy for the transport equations with nonlinear reaction term. As a result two subproblems are obtained. One of which we may apply using the SUPG stabilization while the other equation can be solved analytically. Lastly, numerical experiments are presented to illustrate the good performance of the method.
Application of a three-dimensional printed pelvic model in laparoscopic radical resection of rectal cancer

Introduction To investigate the application value of a three-dimensional (3D) printed pelvic model in laparoscopic radical resection of rectal cancer. Methods Clinical data of patients undergoing laparoscopic radical rectal cancer surgery in The Second People's Hospital of Lianyungang City from May 2020 to April 2022 were selected. Patients were randomly divided into general imaging examination group (control group, n=25) and 3D printing group (observation group, n=25) by random number table method, and the perioperative situation of patients in the two groups was compared. Results There was no significant difference in general data between the two groups (p>0.05). Operation time, intraoperative blood loss, intraoperative time to locate inferior mesenteric artery, intraoperative time to locate left colic artery, first postoperative exhaust time and length of hospital stay in the observation group were all lower than those in the control group (P < 0.05); There were no significant differences in the total number of lymph nodes and complications between the two groups (P > 0.05). Discussion The application of 3D printed pelvic model in laparoscopic radical resection of rectal cancer is conducive to understanding pelvic structure and mesenteric vascular anatomy, reducing intraoperative bleeding and shortening operation time, which is worthy of further clinical application.
Typhoons and their upper ocean response over South China Sea using COAWST model

The formation and intensification of typhoons is a complex process where energy and mass exchanges happen between the ocean and the atmosphere. In most typhoon numerical studies, a static ocean and a dynamic atmosphere are used to reduce the complexity of modeling. Using the COAWST model, we studied the air-sea interactions of Typhoon Mujigae in 2015, Typhoon Merbok in 2017, and Typhoon Hato in 2017 over the South China Sea. With different translation speeds, track shapes, and intensities between these cyclones, they act as an excellent case study to analyze the air-sea coupling in the models. The inclusion of coupling between the ocean and atmosphere is found to improve the typhoon track simulation significantly. The bias in the cyclone tracks is reduced by 10%–40% in the coupled model. The upper ocean response to the typhoon was also analyzed using the coupled model output. The coupled simulations show that the major energy extraction occurs to the right of the track, which is consistent with satellite observation and latent heat release analysis. The coupling process shows the air-sea interactions and exchanges in the upper ocean along with the energy released during the passage of typhoons. The heat budget analysis shows that the cooling of the upper ocean is mainly attributed to the advection associated with the typhoon forcing. This study shows that it is necessary to include ocean feedback while analyzing a typhoon, and the application of coupled models can improve our understanding as well as the forecasting capability of typhoons.
Atherosclerosis treatment with nanoagent: potential targets, stimulus signals and drug delivery mechanisms

Cardiovascular disease (CVDs) is the first killer of human health, and it caused up at least 31% of global deaths. Atherosclerosis is one of the main reasons caused CVDs. Oral drug therapy with statins and other lipid-regulating drugs is the conventional treatment strategies for atherosclerosis. However, conventional therapeutic strategies are constrained by low drug utilization and non-target organ injury problems. Micro-nano materials, including particles, liposomes, micelles and bubbles, have been developed as the revolutionized tools for CVDs detection and drug delivery, specifically atherosclerotic targeting treatment. Furthermore, the micro-nano materials also could be designed to intelligently and responsive targeting drug delivering, and then become a promising tool to achieve atherosclerosis precision treatment. This work reviewed the advances in atherosclerosis nanotherapy, including the materials carriers, target sites, responsive model and treatment results. These nanoagents precisely delivery the therapeutic agents to the target atherosclerosis sites, and intelligent and precise release of drugs, which could minimize the potential adverse effects and be more effective in atherosclerosis lesion.
Limb girdle muscular dystrophy 23 caused by compound heterozygous mutations of LAMA2 gene

Introduction Mutations of LAMA2 gene are associated with congenital muscular dystrophy (CMD). The LAMA2-related CMD mainly consists of two diseases, merosin deficient congenital muscular dystrophies type 1A (MDC1A) and limb girdle muscular dystrophy 23 (LGMD23). LGMD23 is characterized by slowly progressive proximal muscle weakness, which primarily affects the lower limbs and results in gait difficulties. Additional clinical features include increased serum creatine kinase, abnormal electromyography with or without white matter abnormalities on brain imaging. Methods Clinical data were collected from a Chinese Han family. Whole-exome sequencing, Sanger sequencing, RT-PCR and TA clone sequencing were performed on the family members. Results Compound heterozygous mutations of LAMA2: c.1693C > T (p. Q565*) (maternally inherited) and c.9212-6T > G (paternally inherited) were identified and confirmed in the proband. The mutation c.1693C > T (p. Q565*) was classified as pathogenic according to American College of Medical Genetics and Genomics (ACMG) guidelines. By performing RT-PCR and TA clone sequencing, an insertion of 40-bp intronic sequence (intron 64) was found in the transcripts of the proband and her father, which resulted in a frameshift and premature truncation codon of the LAMA2. In particular, the variant truncated the LamG domain of the LAMA2. Therefore, the c.9212-6T>G was classified as likely pathogenic according to American College of Medical Genetics and Genomics (ACMG) guidelines. Discussion Our findings described two novel mutations in a girl with LGMDR23, which contributes to the genetic counseling of the family and expands the clinical and molecular spectrums of the rare disease.
Genome-wide identification of the AcMADS-box family and functional validation of AcMADS32 involved in carotenoid biosynthesis in Actinidia

MADS-box is a large transcription factor family in plants and plays a crucial role in various plant developmental processes; however, it has not been systematically analyzed in kiwifruit. In the present study, 74 AcMADS genes were identified in the Red5 kiwifruit genome, including 17 type-I and 57 type-II members according to the conserved domains. The AcMADS genes were randomly distributed across 25 chromosomes and were predicted to be mostly located in the nucleus. A total of 33 fragmental duplications were detected in the AcMADS genes, which might be the main force driving the family expansion. Many hormone-associated cis-acting elements were detected in the promoter region. Expression profile analysis showed that AcMADS members had tissue specificity and different responses to dark, low temperature, drought, and salt stress. Two genes in the AG group, AcMADS32 and AcMADS48, had high expression levels during fruit development, and the role of AcMADS32 was further verified by stable overexpression in kiwifruit seedlings. The content of α-carotene and the ratio of zeaxanthin/β-carotene was increased in transgenic kiwifruit seedlings, and the expression level of AcBCH1/2 was significantly increased, suggesting that AcMADS32 plays an important role in regulating carotenoid accumulation. These results have enriched our understanding of the MADS-box gene family and laid a foundation for further research of the functions of its members during kiwifruit development.
Trace minerals in poultry feed ingredients

Samples of cereals, cereal by-products deoiled cakes were collected from the feed processing unit, (Project Directorate on Poultry (PDP), Hyderabad) and 4–6 different places of production to examine the variation in trace mineral composition. Feed ingredients collected from PDP indicated that the Mn content of maize, jowar, bajra and broken rice (4.8, 18.0, 13.9 and 15.0 ppm, respectively) was comparable with the NRC values. Deoiled cakes/meals and brans exhibited similar variability in the Mn content. The concentration of Zn and Cu in grains, cereal byproducts and deoiled cakes/meals varied moderately from that of NRC values. However, the Fe content was widely divergent.
Lensless coherent imaging by sampling of the optical field with digital micromirror device

We have experimentally demonstrated a lensless coherent microscope based on direct registration of the complex optical field by sampling the pupil with a sequence of two-point interferometers formed by a digital micromirror device. Complete registration of the complex amplitude in the pupil of the imaging system, without any reference beam, provides a convenient link between the experimental and computational optics. Unlike other approaches to digital holography, our method does not require any external reference beam, resulting in a simple and robust registration setup. Computer analysis of the experimentally registered field allows for focusing the image in the whole range from zero to infinity, and for virtual correction of the aberrations present in the real optical system, by applying the adaptive wavefront corrections to its virtual model.

Socio-economic position and common mental disorders Longitudinal study in the general population in the UK

Declaration of interest None. Previous cross-sectional studies have shown that people in lower socio-economic groups have an increased prevalence of common mental disorders (Holzer et al, 1986; Bijl et al, 1998; Davey Smith et al, 1998; Lewis et al, 1998; Muntaner et al, 1998; Weich & Lewis, 1998a). Cross-sectional studies cannot distinguish whether low socioeconomic position is associated with the development of new episodes of common mental disorders, with increased duration of episodes or both (Muntaner et al, 2004). Psychiatric disorders often show a chronic course (Sargeant et al, 1990) and it is likely that patients in the lower socioeconomic groups might have a worse prognosis rather than an increased risk of a new episode of disorder (Lewis et al, 1998). Previous longitudinal studies have generally supported this observation (Weich & Lewis, 1998b) and a recent meta-analysis found stronger evidence in favour of an association with increased duration (Lorant et al, 2003). However, other studies have found that low socio-economic position may be a risk factor for the development of a new episode (Kaplan et al, 1987; Bruce et al, 1991). These conflicting results may be explained by the different samples and method used, and the inability to adjust for a number of potential confounders. In particular, it is not clear whether all previous studies adjusted for baseline psychiatric symptoms, even though this variable shows a strong association with persistence of disorder (Sargeant et al, 1990; Spijker et al, 2001). Similarly, subthreshold symptoms may confound the association between low socio-economic position and development of a new episode of disorder. Clarifying whether low socioeconomic position is associated with increased risk of a new episode of common mental disorder or with worse prognosis is critical from both an aetiological point of view and a public health perspective. The aim of our study was to investigate this issue in a longitudinal, general-population study in the UK. Based on the previous findings we predicted that participants of lower socio-economic position would be more likely to report an episode of a common mental disorder at follow-up and that this association would be stronger in those who were categorised as cases at baseline compared with non-cases.
Real time object detection method based on improved attention transfer

: Recently, deep neural networks need to be deployed with low memory and computing resources, so it is necessary to design an efficient and compact network structure. This paper proposed a model compression method (KE) based on improved attention transfer for the design of compact neural networks, which mainly used a wide residual teacher network (WRN) to guide a compact student network (KENet) by extracting both spatial and channel-wise attention to improve the performance, and applied this method to real-time object detection. The image classification experiment on CIFAR verified that the knowledge distillation method with improved attention transfer can improve the performance of the compact model. The object detection experiment on VOC verified that the model KEDet has good accuracy (72.7mAP) and time performance (86FPS) . The experimental results show that the object detection model based on improved attention transfer has good accuracy and real-time performance.
Comparision of Dynamic and Greedy Approach for Knapsack Problem

The aim of paper is to analyze few algorithms of the 0/1 Knapsack Problem. This problem is a combinatorial optimization problem in which one has to maximize the benefit of objects without exceeding capacity. As it is an NP-complete problem, an exact solution for a large input is not possible. Hence, paper presents a comparative study of the Greedy and dynamic methods. It also gives complexity of each algorithm with respect to time and space requirements. Our experimental results show that the most promising approaches is dynamic programming. Keywords-knapsack, dynamic programming, greedy programming, NP-Complete, complexity

Simulation study of collisional effects on the propagation of a hot electron beam and generation of Langmuir turbulence for application in type III radio bursts

Abstract The propagation of a localized beam (cloud) of hot electrons and generation of Langmuir waves are investigated using numerical simulation of the quasi-linear equations in the presence of collisional effects for electrons and beam-driven Langmuir waves. It is found that inclusion of the collisional damping of Langmuir waves has remarkable effects on the evolution of the electron distribution function and the spectral density of Langmuir waves, while the effect of collision term for electrons is almost negligible. It is also found that in the presence of collisional damping of Langmuir waves, the relaxation of the beam distribution function in velocity space is retarded and the Langmuir waves are strongly suppressed. The average propagation velocity of the beam is not constant and is larger when collisional damping of Langmuir waves is considered. The collisional damping for electrons does not affect the upper boundary of the plateau but the collisional damping of Langmuir waves pushes it towards small velocities. It is also found that the local velocity of the beam and its width decrease when the collisional damping of Langmuir waves is included.
The Impact of Loving-Kindness Meditation on Compassion Fatigue of Nurses Working in the Neonatal Intensive Care Unit

Compassion fatigue is a common complication in nurses, which can lead to burnout, job dissatisfaction, and a decline in the quality of patient care. This study aimed to investigate the impact of loving-kindness meditation on compassion fatigue of nurses working in the neonatal intensive care unit (NICU). This cluster-blinded randomized clinical trial study was conducted on 66 NICU nurses in 2 educational hospitals selected. The intervention group received a 1-month online program for daily training and practice of loving-kindness meditation. The control group received miscellaneous files on mental health during the COVID-19 pandemic period. The Nursing Compassion Fatigue Inventory (NCFI) was filled out by the 2 groups, before and after the intervention. The results showed that the mean scores of the NCFI in the intervention group decreased significantly compared with before the intervention (P = .002). In comparison with the control group, there was a significant difference between the mean scores of the 2 groups after the intervention (P = .034). Among nurses working in NICU, loving-kindness meditation significantly reduces compassion fatigue after 1 month. These findings support the use of this intervention for nurses.
Standard for 21 ST Century Teachers in Exploring from Pre Service (Caterpillar) Stage to in Service Stage (Butterfly) in Education Field

: The need for an ideal teacher in this present age is crucial and of utmost importance. Teaching is one of the most lucrative jobs in the world, because education is the bedrock of other occupations. The functions and significance of teachers cannot be estimated in this present age. Teachers are paramount and influential agents in the global world today; The different stages of teaching has to be implemented with every form of seriousness, because of the changing world we are living in, of which the education sector is not left out. Certain stages and practices is expected of an ideal teacher, there has to be a developments age which will migrate the teacher from the pre-service (caterpillar stage) to in service (butterfly stages), to that effect the student teachers in education field should be taught right from their early stage before they graduate from the school system. Every potential teacher should have gone through these stages of development in education to become an n-service teacher, there are also prescribed standards expected to be followed and skills to be acquired and this paper gives the need for student teaching practice to be looked into, more emphasized and highly recommendable for all aspiring teachers and those who have flair for
A LITERATURE REVIEW OF RADIOLOGICAL FINDINGS TO GUIDE THE DIAGNOSIS OF GALLBLADDER ADENOMYOMATOSIS.

Background: Gallbladder adenomyomatosis (GA) is a benign gallbladder entity discovered as an asymptomatic gallbladder mass. Since gallbladder cancer is in the differential diagnosis for gallbladder masses, the ability to differentiate benign disease avoids a more extensive oncologic resection. This study sought to review imaging modalities used to diagnose GA. Methods: PubMed and SciVerse Scopus were systematically searched using the terms: “gallbladder adenomyomatosis” and “gallbladder imaging” for articles published between January 2000 and January 2015. Results:Atotal of 14 articles were reviewed in this analysis. Contemporary series report the use of ultrasound (US), computed tomography (CT) or magnetic resonance imaging (MRI) in GAimaging. Ultrasound detection of Rokitansky-Aschoff sinuses, visualized as small cystic spaces with associated “comet-tail” or “twinkling” artifact, is pathognomonic for GA. A “Pearl-Necklace” sign of small connected sinuses on MRI or “Rosary” sign on CT are additional characteristics that may assist in establishing a diagnosis. Conclusion: Ultrasound is the most commonly used tool to investigate GA. If not diagnostic, CT or MRI are effective in attempting to differentiate a benign or malignant cholecystic mass. Characteristic signs should lead the surgeon to perform a laparoscopic cholecystectomy in symptomatic patients or manage non-operatively in asymptomatic patients
