Sleep Disorders and Dual Masculine Desires in Charles Dickens's “Lying Awake” and “Night Walks”
Authors: Lewis Daniel 
Published: April 2020

AbstractCharles Dickens's examinations of sleep, dreaming, and sleep disorders illustrate a complicated negotiation between hegemonic ideals of masculinity that rest on notions of bodily control and mental acuity, but they also present an ambivalent (and sometimes adventurous) position open to expanding the definition of masculinity to include a desire to relinquish mental and physical control. Hegemonic masculine ideals are often in tension with one another, and Dickens explores the specific control–freedom contradiction in personal essays, namely “Night Walks” and “Lying Awake.” While the depiction of the bedroom as a space of male anxiety appears throughout Dickens's work, he expresses this idea most clearly and directly in the above nonfiction texts. The nonfiction essay, over and against the fictional text, allows Dickens to write about sleep disorders and their relation to male anxiety in more personal and pragmatic terms, and to represent the issue in detail without having to be concerned about plot and characterization.
The Oceanic Silence of Rebecca Horn
Authors: Halstead India 
Published: April 2020

AbstractIn this article, I reconsider the early work of artist Rebecca Horn as situated at the threshold of complex new theoretical, political, and artistic movements. Horn's performance pieces of the late 1960s and early 1970s formally echo this social upheaval, vibrating with tension between intimacy and isolation, pleasure and pain, human and machine. Horn's prosthetic sculptures gesture toward a continuity between body and world reminiscent of the Radical Freudian concept of Eros, echoed in the body art and sexual liberation movements of the 1960s, in which the body becomes a fluid expression of polymorphous, nonbinary desire. The sinister backdrop of postwar Germany, however, haunts the artist's work to the extent that silence becomes a motif of its own. Through her work, I ask the question: can the oceanic vision of a genderless Eros be realized, while the wounds of atrocity and of patriarchy are still inscribed on the body, or must polymorphous fluidity remain a fantasy, a utopia deferred?
Minority Report
Authors: Jones II Darryl L. 
Published: April 2020

AbstractBlack men are an integral part of the American pornographic industry, but their participation requires confronting and navigating a variety of simplified categorizations and assumptions that favor their sexuality over their humanity. Utilizing interviews with twelve prominent heterosexual black male figures (also known as “talent”) currently active in the industry, this article seeks to offer insight into the realities that the men face while participating in an industry viewed as taboo by mainstream society. Among the issues explored are their reasons for joining the industry, interracialism and racism, and moral and ethical dilemmas. Also employed are Lewis Gordon's concept of “epistemic closure,” or the cessation of inquiry, and Frantz Fanon's concept of the “phobogenic object,” or “stimulus to anxiety.”

BACKGROUND: In hospitals, some problems still exist, such as transfusion reaction that cannot be dealt with in time, medical staff cannot observe the physiological information of the infusion patients in real time, and the infusion speed cannot be controlled smartly. OBJECTIVE: To address these problems, we propose a method for intelligent monitoring and designed a controller for dripping speed regulation. METHODS: A photoelectric sensor was used to obtain the heart rate (HR) information, and a PID parameter self-tuning controller based on the fuzzy control principle was developed to establish a multi-stage adaptive control method based on HR feedback. By controlling the rotation of the motor to drive the cam to control the drip rate smartly. Also, the infusion and physiological information are transmitted to the nurse station to monitor the possible transfusion reaction. RESULTS: The experiments show that the intelligent infusion controller can achieve HR signal detection with an average accuracy of over 94%, dripping speed detection and adjustment with an average accuracy of above 98% and adjustment time within 35 seconds. CONCLUSION: Our study proved that the intelligent infusion controller can control the infusion process intelligently and effectively, and has excellent reliability, small steady-state error and high practical value.

OBJECTIVE: Single-photon emission computed tomography (SPECT) as well as dual energy X-ray absorptiometry (DXA) scanners were designed in July 2018 at the Nuclear Medicine Department (NM), of the Taiwan Medical University Hospital. These scanners emit substantial X-rays from the target, which are tungsten, iron. Therefore, patients undergoing SPECT and DXA diagnosis, in addition to medical personnel, are exposed to undesirable photon leakage. METHODS: Following administration of radiopharmaceuticals, patients become radioactive sources; thus, it is necessary to evaluate a possible increase in the environmental gamma exposure rates in the NM as a result of the operation of the new scanners. A three month evaluation of environmental radiation in the NM was performed using the accurate and sensitive TLD-100H approach, which gives an error rate less than 10%. RESULTS: Detected exposure radiation rates in the NM ranged from 0.12 [Formula: see text] 0.02 to 1.00 [Formula: see text] 0.15 mSv per month, indicating that the imaging room had significantly different radiation rates. The results were compared with previous results, and no significant contribution to the enhancement of environmental gamma radiation was detected, which remained far below the occupational dose recommended by ICRP 60. The minimum detectable dose (MDD) for environmental radiation is also discussed herein to demonstrate the reliability of TLD-100H. CONCLUSION: Recommendations were sent to the authorities of AEC-ROC to implement actions that could reduce doses at these high-dose locations to meet the ALARA principle.

Authors: Lee Gihyoun , Park Ji-Su , Cho Hong-Sig , Lee Bong-Choon , Jung Young-Jin 
Published: April 2020

BACKGROUND: Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that can help modulate cortical excitability by transmitting direct current (DC) between a pair of scalp electrodes. To date, most studies on tDCS have been relatively short-lived, and the DC stimulations only lasted a few minutes. Conventional tDCS devices usually have some problems such as needing a lot of patches and lead lines. OBJECTIVE: Since conventional tDCS devices are unsuitable for use in long-term stimulations, we developed a new tDCS which can easily be used by unskilled persons. METHODS: We developed a new tDCS device that does not have lead lines for tDCS electrodes and has a simple structure. RESULT: This device can achieve stimulation with polarity interchangeable DC without physically swapping the anode and cathode. The performance of the proposed device was verified through an experiment. CONCLUSION: The developed tDCS device can contribute to long-term research as it uses neuroelectric stimulation.

BACKGROUND: Variations or malformation of the internal carotid artery (ICA) and basilar artery (BA) can be risk factors during simple surgery. So medically the focus has been on information about the positional relationship between the blood vessels based on the distance and angle between the ICA and BA. OBJECTIVE: This study measured the distance and angle between the ICA and BA in 188 healthy Korean male and female subjects in their 20s and 40s and analyzed the differences in terms of age and gender. METHODS: Magnetic resonance images were obtained; the distance between the right ICA and BA was defined as R1 [cm], the distance between the left ICA and BA was defined as L2 [cm], and the distance between the right ICA and left ICA was defined as M3 [cm]. The angles between the right and left ICA and BA were defined as AR1 [degree] and AR2 [degree], respectively. RESULTS: With increasing age, R1 and M3 became shorter in both men and women, and L2 became shorter only in women. CONCLUSION: The results of this study provide data on the average distance and angle between the ICA and BA of healthy Korean men and women in their 20s and 40s, which may later be used to support the diagnosis of relevant brain diseases and simple routine surgical procedures.

OBJECTIVE: We aimed to observe and investigate the clinical significance of vascular endothelium growth factor (VEGF) levels in exhaled breath condensate (EBC) from patients with acute respiratory distress syndrome (ARDS). METHODS: An improved EcoScreen condenser was used to collect EBC from 31 ARDS patients on mechanical ventilation and from 22 healthy subjects. Serum and EBC VEGF levels were analyzed with ELISA. VEGF levels in the EBC of patients with different grades of lung injuries were analyzed. The correlation between VEGF levels and clinical indicators was analyzed. RESULTS: Serum and EBC VEGF levels were linearly and positively correlated with a correlation coefficient of 0.694 ([Formula: see text] 0.01). The VEGF level in the EBC of ARDS patients was significantly lower than that in the control group ([Formula: see text] 0.01). The VEGF level in the EBC of the mild ARDS group was higher than that in the moderate-severe ARDS group ([Formula: see text] 0.01). The VEGF level in the EBC of the survival group was higher than that in the mortality group. The VEGF level in the EBC of ARDS patients was positively correlated with PaO[Formula: see text]/FiO[Formula: see text] and PaO[Formula: see text] and was negatively correlated with lung injury score (LIS) and A-aDO[Formula: see text]/PaO[Formula: see text]. CONCLUSION: The changes in VEGF levels in the EBC of ARDS patients can Respiratory Medicine, reflect the severity of lung injury. Therefore, VEGF level in EBC can be used as an auxiliary index for judging the severity and prognosis of ARDS patients.

Authors: Hu Fan , Jing Limei , Shi Rong 
Published: April 2020

BACKGROUND: In recent years, air pollution and the number of children with respiratory tract infections increased. This also increased the burden related to the treatment of disease, so the government and relevant departments need to strengthen their management. OBJECTIVE: The aim of the present study was to quantitatively analyze the relationship between respiratory infection and air quality in children and gain insight into the burden of related diseases. METHODS: Data regarding outpatient and emergency department visits in children of 14 years or younger in 16 public and private medical institutions were collected for four months. Routine air quality monitoring data in Shanghai from the same period were correlated with these medical data by descriptive statistics, Pearson’s correlation analysis and multivariate linear regression analysis. RESULTS: There was a positive correlation between respiratory tract infections in 73376 children and Air Quality Index (AQI), PM2.5, SO[Formula: see text] and NO[Formula: see text] levels. The total medical expense per patient was 80.22 yuan, and the average compensation ratio of medical insurance per patient was 18.95%. The increase in AQI and the concentration of major air pollutants will lead to increased medical treatment for children with respiratory diseases. CONCLUSION: It is suggested that the intensity of air pollution control should be increased, so that the special period of childhood respiratory protection is strengthened. Moreover, child medical insurance coverage should also be moderately increased to safeguard the rights and interests of children’s health.

Published: April 2020

BACKGROUND: The nervous system senses and transmits information through the firing behavior of neurons, and this process is affected by various noises. However, in the previous study of the influence of noise on nerve discharge, the channel of some noise effects is not clear, and the difference from other noises was not examined. OBJECTIVE: To construct ion channel noise which is more biologically significant, and to clarify the basic characteristics of the random firing rhythm of neurons generated by different types of noise acting on ion channels. Method: Based on the dynamics of the ion channel, we constructed ion channel noise. We simulated the nerve discharge based on the Chay model of potassium ion channel noise, and used the nonlinear time series analysis method to measure the certainty and randomness of nerve discharge. RESULTS: In the Chay model with potassium ion noise, the chaotic rhythm defined by the original model could be effectively unified with the random rhythm simulated by the previous random Chay model into a periodic bifurcation process. CONCLUSION: This method clarified the influence of ion channel noise on nerve discharge, better understood the randomness of nerve discharge and provided a more reasonable explanation for the mechanism of nerve discharge.

Authors: Yu Shuchun , Wang Qi , Ru Changhai , Pang Ming 
Published: April 2020

BACKGROUND: Key area location is an important content of medical image processing and an important detail of auxiliary medical diagnosis. OBJECTIVE: In this paper, a prior knowledge fusion method based on Haar-like feature and contour feature is proposed to locate and detect key areas in medical images. METHOD: For the image to be processed, six Haar-like features and five contour features are extracted respectively. The improvement of Haar-like feature extraction template better adapts to the complexity of regional structure of medical images. The design of the contour feature extraction process fully reflects the consideration of feature invariance. The two features, together with prior knowledge, are fed into their respective decision makers and final fusers as the basis for determining and locating key regions. RESULTS: The experimental results show that the proposed method has excellent performance in locating key regions of medical images on MRI. When the capacity of the database increases from 10 to 200, the accuracy of locating the key areas of the image to be processed still reaches more than 90%. CONCLUSION: The proposed method realizes the accurate location of the key areas of medical images, which is of great significance for the auxiliary medical diagnosis.

Published: April 2020

BACKGROUND: Microscopic image analysis based on image processing is required for quantitative evaluation of decellularization. Existing methods are not widely used because of expensive commercial software, and machine learning-based techniques lack generality for decellularization because many high-resolution image data has to be processed. OBJECTIVE: In this study, we developed an image processing algorithm for quantitative analysis of tissues and cells in a general microscopic image. METHODS: The proposed method extracts the color images obtained by the microscope into reference images consisting of grayscale, red (R), green (G), and blue (B) information and transforms each into a binary image. The transformed images were extracted by separating the cells and tissues through outlier noise elimination, logical multiplication and labeling. In order to verify the method, decellularization of porcine arotic valve was performed by the electrical method. Slice samples were obtained by time and the proposed method was applied. RESULTS: The experimental results show that the segmentation of cells and tissues, and quantitative analysis of the number of cells and changes in tissue area during the decellularization process was possible. CONCLUSIONS: The proposed method shows that cell and tissue extraction and quantitative numerical analysis were possible in different brightness of microscopic images.

Most anticancer drugs like doxorubicin (DXR) have low specificity that results in undesirable effects especially when it comes to collateral effects on reproduction. Plants are excellent sources when searching for new drugs. Auxemma oncocalyx (A. oncocalyx) and its main component Oncocalyxone A (onco A) have anti-tumoral activity and are less toxic than DXR in reproductive parameters. However, there are no studies on the action of these drugs regarding the porcine in vitro oocyte competence and embryo development. The aim of this study was to evaluate the effect of A. oncocalyx and onco A exposure during in vitro maturation (IVM) of oocytes (Experiment 1) or in vitro embryo culture (IVC) (Experiment 2) on the oocyte developmental competence. For experiment 1, COCs were distributed in IVM medium alone (control) or supplemented with DXR (0.3 g/mL), A. oncocalyx (1.2 g/mL) and onco A (1 g/mL). Then, oocytes were submitted to in vitro fertilization (IVF) and in vitro embryo culture. For experiment 2, zygotes were cultured with DXR, A. oncocalyx and onco A for 7 days. Viability, maturation, fertilization and embryo developmental parameters were evaluated in both experiments. In experiment 1; DXR, A. oncocalyx and onco A reduced (P<0.05) oocyte viability and IVM efficiency. Onco A increased (P<0.05) the meiotic resumption. After IVF, all drugs reduced (P<0.05) viability, IVF efficiency and percentage of cleaved embryos, nevertheless, only DXR decreased the percentage of blastocyst. In experiment 2; all drugs reduced (P<0.05) the percentage of penetration, but only DXR and onco A decreased (P<0.05) IVF efficiency. DXR and A. oncocalyx decreased (P<0.05) the percentage of cleaved embryo, but had no effect on blastocyst formation. In conclusion, the addition of DXR during IVM or IVC negatively affected the IVF efficiency and cleavage rate. In addition, the exposure of COCs to DXR only during IVM was more detrimental to oocyte viability and blastocyst formation than A. oncocalyx and onco A.

Hydraulic Model Calibration and Performance Assessment of Pressure Managed Areas with Multiple Inlets
Authors: Bibok Attila , Fülöp Roland 
Published: April 2020

Pressure management is a widely adopted technique in the toolset of drinking water distribution system operators. It has multiple benefits, like reducing physical losses in pipe networks with excessive leakage, prolong the expected lifetime of the pipes and protecting home appliances from unacceptably high pressure. In some cases, even legislation compliance can be the motivation behind pressure management: It is mandatory to supply water at the customer’s connection between 1.5 and 6.0 bar in Hungary since 2011. Diaphragm pressure reducing valves are widespread in the drinking water distribution networks. Although, their sensitivity for gas pocket accumulation in the valve house makes hydraulic calibration of these pressure managed areas a challenging task for hydraulic modelers and network operators. This is especially true when more than one inlet is used to supply the same area in order to increase resilience and flow capacity.This paper investigates the hydraulic properties of pressure reduced areas with multiple inlet points. Model calibration using a single valve and minor loss was found insufficient because the additional pressure loss referenced to the pressure setting has a non-quadratic relationship with flow-rate on the discharge side under real-life circumstances. This phenomenon can be handled by using a PRV (pressure reducing valve) + GPV (general purpose valve) in series.
