Anaesthetic Challenges in a Case of Oral Carcinoma With Anticipated Difficult Airway Posted for Tumour Excision and Reconstruction Surgery

Mandibular surgery, edentulous jaw, denture wear, and ageing are all risk factors for persistent mandibular ridge resorption and weakening. The tongue occludes the upper airway due to the mandible's edentulous condition. All of these factors contribute to the difficulties in regulating the airway. An adequate preoperative review assisted in classifying this index patient as having a high risk of difficult airway management, and appropriate actions were made to facilitate effective airway care. A 60-year-old male presented to casualty with a complaint of squamous cell carcinoma of the right buccal mucosa and was posted for wide local excision of the tumour, segmental mandibulectomy, bilateral modified radical neck dissection, and reconstruction with a fibular free flap. He had a restricted mouth opening and a heavy jaw, with Mallampati grade 4 and had an anticipated difficult airway. Hence, awake endotracheal intubation was done by flexible fibreoptic bronchoscope following airway blocks and an 8.0 mm cuffed flexometallic armoured tube was secured at 28 cm at the angle of the nose. Bilateral modified radical neck dissection and wide local excision of the tumour were done followed by mandibulectomy and its reconstruction by fibular free flap and anastomosis was performed. Tracheostomy was performed and the patient was shifted to the intensive care unit and kept knocked out with injection vecuronium and injection midazolam infusion. The patient was gradually weaned off the ventilator the following day and discharged on postoperative day 12 with minimal postoperative complications. A thorough pre-anaesthetic plan, simple and skilled anaesthetic management strategy, and well-organized teamwork aided in the effective anaesthetic care of this challenging airway patient.
Enhancing Stability of DC Microgrids Employing SMES-Battery Hybrid Energy Storage System

Robust operation of DC microgrids is seriously jeopardized by renewable energy sources fluctuations and intermittency, abrupt load changes and unscheduled disconnections from the utility grid. These disturbances can cause DC bus voltage instability and power quality issues. Therefore, utilization of properly controlled energy storage systems, plays a substantial role for a smooth and secure operation, especially in islanded operation mode. However, frequent cycling operation and high charging/discharging rates render the (energy-type) battery storage systems unsustainable solution due to their quick lifetime reduction. On the other hand, (power-type) superconducting magnetic energy storage (SMES) systems have almost zero lifetime degradation under the aforementioned conditions. This study proposes a PI-droop controlled SMES-battery hybrid energy storage system to enrich the stability of an islanded DC microgrid and extend battery service time, simultaneously. Simulations conducted in PSIM software, demonstrate the effectiveness of the adopted control scheme, in terms of microgrid power quality and battery lifetime extension.
Middle Atmospheric Traveling Waves Forced by Latent and Convective Heating

Abstract The excitation and propagation of equatorial planetary waves and inertia-gravity waves were studied by comparing simulations from the comprehensive GFDL troposphere-stratosphere-mesosphere SKYHI general circulation model (GCM) and from a linear primitive equation model with the same domain and numerical resolution. The basic state of the linear model is time dependent and is derived from the mean zonal wind and temperature obtained from a simulation with the full SKYHI model. The latent and convective heating fields of this SKYHI integration are used as the forcing for the linear model in a parallel simulation. The wavelength and frequency characteristics of the prominent vertically propagating equatorial Kelvin and Rossby-gravity waves are remarkably similar in the linear model and in SKYHI. Amplitudes are also similar in the lower stratosphere, indicating that the latent and convective heating is the dominant mechanism producing equatorial wave activity in the GCM. The amplitude of these waves .
Design of fractional delay FIR filter based on improved moth flame optimization algorithm

Considering the non-differentiability and multimode of fractional delay (FD) FIR filter, this paper proposes an improved moth-flame optimization (IMFO) algorithm, which combines moth-flame optimization (MFO) algorithm with Lévy flight to improve the search ability of the algorithm. In order to improve the flexibility of traditional filter design method, amplitude and phase weighted fitness function is proposed. In order to verify the reliability of the algorithm, a simulation example is designed to prove that the optimization ability of the algorithm is better than the traditional method and the traditional MFO algorithm.
On-line real-time path planning of mobile robots in dynamic uncertain environment

A new path planning method for mobile robots in globally unknown environment with moving obstacles is presented. With an autoregressive (AR) model to predict the future positions of moving obstacles, and the predicted position taken as the next position of moving obstacles, a motion path in dynamic uncertain environment is planned by means of an on-line real-time path planning technique based on polar coordinates in which the desirable direction angle is taken into consideration as an optimization index. The effectiveness, feasibility, high stability, perfect performance of obstacle avoidance, real-time and optimization capability are demonstrated by simulation examples.

Color constancy from invariant wavelength ratios: I. The empirical spectral mechanism

The wavelengths of several constant hues over four illuminants (D95, D65, D50, A) are derived from several sets of published data. In the plane of wavelength and reciprocal illuminant color temperature (MK−1), the wavelengths of constant hues plot straight approximately parallel lines whose mean slope is about 87°. Parallel lines give invariant wavelength ratios, hence constant hues in this plane are near-invariant wavelength ratios across illuminants. As recently demonstrated, the complementary wavelengths to a constant hue (across illuminants) represent the complementary constant hue; these complementary wavelengths also plot a near-parallel line to the first constant hue. To confirm and further define the constant slope of these lines, it is shown that complementary wavelength pairs, per CIE data, can only plot parallel straight lines at the angle of 87° ± 1. In summary, near-parallel sloping lines represent constant hues at near-invariant wavelength ratios. This mechanism of color constancy is shown to relate to the well-known theory of relational color constancy from invariant cone-excitation ratios. In the visual process, the latter ratios are presumably the source of the former (invariant wavelength ratios). © 2008 Wiley Periodicals, Inc. Col Res Appl, 33, 238–249, 2008
Preliminary Findings of Elevated Inflammatory Plasma Cytokines in Children with Autism Who Have Co-Morbid Gastrointestinal Symptoms

Autism spectrum disorder (AU) is present in approximately 2% of the population and is often associated with co-morbidities that can impact quality of life. One of the most common co-morbidities in autism is the presence of gastrointestinal (GI) symptoms consisting of irregular bowel habits such as constipation, diarrhea, or alternating bowel habit. Evidence of immune infiltration and immune activation has been shown in the ileum and colon of children with AU with GI symptoms. Moreover, immune dysfunction is a contributing factor in many GI diseases, and we hypothesize that it would be more apparent in children with AU that exhibit GI symptoms than those who do not present with GI symptoms. The aim of this preliminary study was to determine whether there are altered cytokine levels in plasma in children with AU with GI symptoms compared with children with AU without GI symptoms, typically developing (TD) children with GI symptoms and TD children without GI symptoms, from the same population-based cohort. Plasma cytokine levels were assessed by multiplex assays. No differences in plasma cytokines were observed in TD controls with or without GI symptoms; however, many innate (IL-1α, TNFα, GM-CSF, IFNα) and adaptive cytokines (IL-4, IL-13, IL-12p70) were increased in AU children with GI symptoms compared with children with AU with no GI symptoms. The mucosal relevant cytokine IL-15 was increased in AU with GI symptoms compared with all groups. In contrast, the regulatory cytokine IL-10, was reduced in AU with GI symptoms and may suggest an imbalance in pro-inflammatory/regulatory signals. These data suggest that children with AU and GI symptoms have an imbalance in their immune response that is evident in their circulating plasma cytokine levels. A finding that could point to potential therapeutic and/or monitoring strategies for GI issues in AU.
Clinical Application of Narrative Therapy in the Treatment of Perinatal Mood and Anxiety Disorder

Pregnancy and postpartum are full of developmental change for both women and their families. Family members are adjusting to their new roles in the family and women are beginning to define their abilities as a mother and caretaker. For some women, their experience during this time is convoluted by the experience of a perinatal mood and/or anxiety disorder (PMAD). In these cases, women's self of competency or mastery in their role as a mother can become entangled, leading to insecurities along with their depression or anxiety symptoms. Medication treatments and psychotherapy interventions have been established to address the mood and anxiety symptoms and to support the family system. However, a treatment is needed that addresses the PMAD symptoms and the internalization of women's feelings and emotions experienced during this impressionable and often defining time. In this article, we explore the use of Narrative Family Therapy as a way to help women deconstruct unhelpful narratives they may have created during pregnancy and postpartum. A case study is provided to illustrate how Narrative Family Therapy can be used to emotionally reauthor women's stories, and construct new meanings by separating their PMAD symptoms from their identity as a mother.
Heavy Metal Contamination in the Aquatic Ecosystem: Toxicity and Its Remediation Using Eco-Friendly Approaches

Urbanization and industrialization are responsible for environmental contamination in the air, water, and soil. These activities also generate large amounts of heavy metal ions in the environment, and these contaminants cause various types of health issues in humans and other animals. Hexavalent chromium, lead, and cadmium are toxic heavy metal ions that come into the environment through several industrial processes, such as tanning, electroplating, coal mining, agricultural activities, the steel industry, and chrome plating. Several physical and chemical methods are generally used for the heavy metal decontamination of wastewater. These methods have some disadvantages, including the generation of secondary toxic sludge and high operational costs. Hence, there is a need to develop a cost-effective and eco-friendly method for the removal of heavy metal ions from polluted areas. Biological methods are generally considered eco-friendly and cost-effective. This review focuses on heavy metal contamination, its toxicity, and eco-friendly approaches for the removal of heavy metals from contaminated sites.
Emerging Role of SMILE in Liver Metabolism

Small heterodimer partner-interacting leucine zipper (SMILE) is a member of the CREB/ATF family of basic leucine zipper (bZIP) transcription factors. SMILE has two isoforms, a small and long isoform, resulting from alternative usage of the initiation codon. Interestingly, although SMILE can homodimerize similar to other bZIP proteins, it cannot bind to DNA. As a result, SMILE acts as a co-repressor in nuclear receptor signaling and other transcription factors through its DNA binding inhibition, coactivator competition, and direct repression, thereby regulating the expression of target genes. Therefore, the knockdown of SMILE increases the transactivation of transcription factors. Recent findings suggest that SMILE is an important regulator of metabolic signals and pathways by causing changes in glucose, lipid, and iron metabolism in the liver. The regulation of SMILE plays an important role in pathological conditions such as hepatitis, diabetes, fatty liver disease, and controlling the energy metabolism in the liver. This review focuses on the role of SMILE and its repressive actions on the transcriptional activity of nuclear receptors and bZIP transcription factors and its effects on liver metabolism. Understanding the importance of SMILE in liver metabolism and signaling pathways paves the way to utilize SMILE as a target in treating liver diseases.
Emerging RUNX2-Mediated Gene Regulatory Mechanisms Consisting of Multi-Layered Regulatory Networks in Skeletal Development

Skeletal development is tightly coordinated by chondrocytes and osteoblasts, which are derived from skeletal progenitors, and distinct cell-type gene regulatory programs underlie the specification and differentiation of cells. Runt-related transcription factor 2 (Runx2) is essential to chondrocyte hypertrophy and osteoblast differentiation. Genetic studies have revealed the biological functions of Runx2 and its involvement in skeletal genetic diseases. Meanwhile, molecular biology has provided a framework for our understanding of RUNX2-mediated transactivation at a limited number of cis-regulatory elements. Furthermore, studies using next-generation sequencing (NGS) have provided information on RUNX2-mediated gene regulation at the genome level and novel insights into the multiple layers of gene regulatory mechanisms, including the modes of action of RUNX2, chromatin accessibility, the concept of pioneer factors and phase separation, and three-dimensional chromatin organization. In this review, I summarize the emerging RUNX2-mediated regulatory mechanism from a multi-layer perspective and discuss future perspectives for applications in the treatment of skeletal diseases.
Automatic Recording Laser Interferometer for Line Standards up to 2 m

A description is given of an automatic recording laser interferometer for calibrating line standards up to 2 m based on Eppenstein's principle, and various factors which limit the measuring accuracies are also investigated in detail. This fringe-counting interferometer uses two corner cube reflectors. One reflector is mounted with the objective of a photoelectric miscroscope on a carriage which moves at a uniform speed of 10 to 300 mm/min on an air track. An electric pulse, which corresponds to the center of a graduation line and is a gate signal for counting interference fringes, is produced by the zero crossing method from the derivative of a signal obtained when the graduation line image goes across a slit. The reflectors generate two different interference fringes in phase quadrature by using their polarization properties in reflection, so that fringe resolving power is raised to λ/16. The experimental results on line standards show that the standard deviation of a graduation line positioning is 0.04 μm and the accuracy of measurement on a 1 m line-interval is 0.08 μm in standard deviation.
Exploring the Effects of EEG-Based Alpha Neurofeedback on Working Memory Capacity in Healthy Participants

Neurofeedback, an operant conditioning neuromodulation technique, uses information from brain activities in real-time via brain–computer interface (BCI) technology. This technique has been utilized to enhance the cognitive abilities, including working memory performance, of human beings. The aims of this study are to investigate how alpha neurofeedback can improve working memory performance in healthy participants and to explore the underlying neural mechanisms in a working memory task before and after neurofeedback. Thirty-six participants divided into the NFT group and the control group participated in this study. This study was not blinded, and both the participants and the researcher were aware of their group assignments. Increasing power in the alpha EEG band was used as a neurofeedback in the eyes-open condition only in the NFT group. The data were collected before and after neurofeedback while they were performing the N-back memory task (N = 1 and N = 2). Both groups showed improvement in their working memory performance. There was an enhancement in the power of their frontal alpha and beta activities with increased working memory load (i.e., 2-back). The experimental group showed improvements in their functional connections between different brain regions at the theta level. This effect was absent in the control group. Furthermore, brain hemispheric lateralization was found during the N-back task, and there were more intra-hemisphere connections than inter-hemisphere connections of the brain. These results suggest that healthy participants can benefit from neurofeedback and from having their brain networks changed after the training.
Expression Characteristics and Sequence Variation Analysis of Rice Starch Regulator 1 Gene in Japonica Rice With Transgressive Variation

The parents and transgressive variation lines of hybrids with significant difference in amylose content were selected to compare and analyze the accumulation characteristics of amylose and the change of OsRSR1 expression in grains in the process of grain filling, and the PCR technology was used to clone the OsRSR1 gene base sequence of four varieties. The results showed that the amylose content in grains increased gradually with grain filling process, the amylose content of offspring and parents with high amylose content were higher than the offspring and parents with low amylose content, hybrids could obtain the transgressive variation lines through the continuous directional selection of amylose content in grain, and the accumulation of amylose content in grain was closely related to genotypes. The expression quantity of OsRSR1 gene in grain was increasing during the grain filling process, the amylose content of grain was closely related to the activity of OsRSR1 gene, and the expression of grain OsRSR1 gene could also produce transgressive variation.
EFFICIENT BOX-CONSTRAINED TV-TYPE-l^1 ALGORITHMS FOR RESTORING IMAGES WITH IMPULSE NOISE

In this paper, we study the restoration of images simultaneously corrupted by blur and impulse noise via variational approach with a box constraint on the pixel values of an image. In the literature, the TV-l variational model which contains a total variation (TV) regularization term and an l data-fidelity term, has been proposed and developed. Several numerical methods have been studied and experimental results have shown that these methods lead to very promising results. However, these numerical methods are designed based on approximation or penalty approaches, and do not consider the box constraint. The addition of the box constraint makes the problem more difficult to handle. The main contribution of this paper is to develop numerical algorithms based on the derivation of exact total variation and the use of proximal operators. Both one-phase and two-phase methods are considered, and both TV and nonlocal TV versions are designed. The box constraint [0, 1] on the pixel values of an image can be efficiently handled by the proposed algorithms. The numerical experiments demonstrate that the proposed methods are efficient in computational time and effective in restoring images with impulse noise. Mathematics subject classification: 65J22, 65K10, 68U10.
Matrix algebra approach to Gabor-type image representation

Properties of basis functions which constitute a finite scheme of discrete Gabor representation are investigated. The approach is based on the concept of frames and utilizes the Piecewise Finite Zak Transform (PFZT). The frame operator associated with the Gabor-type frame is examined by representing it as a matrix-values function in the PFZT domain. The frame property of the Gabor representation functions are examined in relation to the properties of the matrix-valued function. The frame bounds are calculated by means of the eignevalues of the matrix-valued function, and the dual frame, which is used in calculation of the expansion coefficients, is expressed by means of the inverse matrix. DFT-based algorithms for computation of the expansion coefficients, and for the reconstruction of signals from these coefficients are generalized for the case of oversampling of the Gabor space. It is illustrated by an example that a better reconstruction is obtained in from the same number of coefficients in the case of oversampling.
Global and local noise on diffusively coupled neural networks

In this paper the effect of noise on activity of a neural network of diffusively coupled excitatory-inhibitory cells with time delay is analyzed. We distinguish between global and local noise studying the different types of spatiotemporal behaviors observed when a space-time correlated noise is applied to the system. The results show a synchronization of the network in aperiodic behavior with the help of tiny noisy perturbations on the external signal depending on the spatial correlation of noise and the coupling coefficients.
