A Review of High Frequency Ultrasound Systems

Medical ultrasound machines have been dramatically developed because of recent semiconductor development such as integrated circuit and fabrication process technology. However, proper design of ultrasound electronics are still highly desirable to be integrated with high frequency ultrasound electronic systems due to low sensitivity and high noise level caused by mismatching issues between electronic components and ultrasonic transducers. Additionally, the large parasitic capacitances and inductances of electronic components are bottleneck to design high performance ultrasound electronics. Therefore, this article which provides appropriate electronics design for high frequency ultrasound systems including integration issues with other medical imaging modalities are reviewed and discussed. Keywords—High frequency ultrasound electronics; Ultrasound transducers; Ultrasound systems

Anomalous Object Tracking in Distributed Camera Network

—The paper introduces a novel framework for real-time tracking of an object with higher precision in a Pan-Tilt-Zoom (PTZ) camera network. In the above-mentioned framework, the object which behaves anomalously is picked for tracking. An SVM classifier has been used to pick anomaly behaving object among all the objects present in a frame. It is a self-initializing algorithm as it does not require user intervention for object detection. Target detection is followed by its autonomous tracking in the distributed camera network. Hence it does not make the system bulky and takes less time to execute. The paper implements multiple object tracking using Discriminative Correlation Filtering with Channel and Spatial Reliability(CSR-DCF) tracking algorithm. Existing works are based on Particle filtering or Kalman filtering algorithms which are computationally complex and not self-initializing.
FACTORS INFLUENCING BOY CHILD RETENTION IN PUBLIC DAY SECONDARY EDUCATION IN NYAMIRA SUB COUNTY, KENYA

Despite the fact that the government of Kenya has introduced free day secondary education (FDSE) many school going aged students are at home, also repetition and dropout rate continues to rise. Although many studies have been carried out in other parts of Kenya, none has investigated the factors behind the increased dropout rate of the boy child in secondary education particularly in Nyamira Sub County. The purpose of this study was to explore the factors facing the boy child’s retention in secondary education in Nyamira Sub County. The objectives of the study were: to find the extent to which household factors and school factors influence retention of the boy child in public day secondary education. The study used mixed methods research design.This study was guided by systems theory of organizations in an attempt to find out selected factors that influenced boy child’s retention to secondary education in Nyamira Sub County together with a conceptual framework.The units of analysis were 33 public day secondary schools. The target population was 33 principals, 33 HODs guidance and counseling, 33 Chairpersons of Parents association (PA), 47 Class teachers, 2 ZQASOs and 1935 students. Krejcie and Morgan sample size determination table was used to select a sample of 28 principals, 28 chair persons of PA and 28 HODs G/C, 42 class teachers and 321 students selected through stratified random sampling, and 2DQASOs were picked out through purposive sampling. Questionnaires, Interview schedule and document analysis were used to collect data which was analyzed and coding done before data analysis. Quantitative data was analyzed using regression data analysis. Qualitative data was analyzed in an ongoing process as themes and sub themes emerged from the study. On the issue of household factors facing the boy child, the study revealed that family income, labour needed at home and level of education of parents were critical. On the concern about school related factors severe punishment, promotion standards, cost of education and lunch fees balance were the main factors. The study results would be used to provide useful information to the policy makers on the implementation of workable strategies that will promote boys’ education and provide a basis upon which other related studies can be anchored. It was concluded that the household factors greatly influenced boy child retention in secondary education. Information gathered would contribute to knowledge by analyzing factors and situations that limit boychild retention in secondary education.

Electrical characteristics of oxide-nitride-oxide films formed on tunnel-structured stacked capacitors

Current conduction mechanism of oxide-nitride-oxide films formed on tunnel-structured stacked capacitor (TSSC) was studied. At positive and negative bias, the Poole-Frenkel (P-F) conduction of holes in the nitride (SiN/sub x/) film dominates the total leakage current. From the P-F plot, the relative dielectric constant of the SiN/sub x/ was calculated. The electric field inside the structure was also calculated by assuming the model that characterizes the electrode shape inside the tunnel. From the results, the reason why the reliability of the TSSC is not lowered in comparison with the conventional stacked capacitor is discussed. >
Effects of nasal irrigation after endoscopic transsphenoidal resection in patients with pituitary adenomas

Supplemental Digital Content is available in the text Abstract Purpose: We aimed to explore the methods to reduce or prevent nasal complications after endoscopic transsphenoidal pituitary adenoma resection. We also examined the effects of nasal irrigation after this procedure was performed. Methods: A randomized controlled trial was performed. Sixty patients of a tertiary hospital were enrolled in this study. The subjects were randomly divided into a control group and an intervention group. The subjects of the control group were given routine guidance, and 20 mL of normal saline was atomized through inhalation. The gauze was removed 7 days after surgery. The patients of the intervention group were given 50 mL of a 2% saline solution at 37°C to 38°C for bilateral nasal irrigation for 1 week. After that, patients were given 50 mL of a 0.9% normal saline solution at 37°C to 38°C for bilateral nasal irrigations. The complications of the two groups were collected at baseline, 1 week after intervention, 1 month, and 3 months after intervention. The data were analyzed using the chi-square test. Results: A 1-month after intervention, there were significant differences in dysosmia, epistaxis, and nasal adhesion between the intervention and control groups. A 3-month after intervention, only olfactory disturbances were significantly different between the two groups. Conclusions: Nasal irrigation helps reduce the incidence of complications such as epistaxis and nasal adhesions in the early postoperative period. It can also promote the elimination or reduction of olfactory disturbances.

A systematic review of person-centred adjustments to facilitate magnetic resonance imaging for autistic patients without the use of sedation or anaesthesia

Magnetic resonance imaging is widely used for different diagnostic examinations involving autistic patients. The noisy, narrow, isolating magnetic resonance imaging environment and long scan times may not be suitable for autistic individuals, given their communication challenges, sensory sensitivities and often heightened anxiety. This systematic review aims to reveal any reasonable and feasible radiography-based adjustments to facilitate magnetic resonance imaging scanning without the use of sedation or general anaesthesia. Nine electronic databases were systematically searched. Out of 4442 articles screened, 53 were deemed directly relevant; when assessed against eligibility criteria, only 21 were finally included in this systematic review. Customising communication was found to be a key adjustment, as well as scan-based optimisation and environmental adaptations. The importance of distraction techniques and use of technology for familiarisation with the processes was also highlighted. The results of this study can inform recommendations to improve magnetic resonance imaging practice and patient experience, without the use of sedation or anaesthesia, where feasible. They can also inform the basis of dedicated training for magnetic resonance imaging radiographers. Lay abstract Autistic patients often undergo magnetic resonance imaging examinations. Within this environment, it is usual to feel anxious and overwhelmed by noises, lights or other people. The narrow scanners, the loud noises and the long examination time can easily cause panic attacks. This review aims to identify any adaptations for autistic individuals to have a magnetic resonance imaging scan without sedation or anaesthesia. Out of 4442 articles screened, 53 more relevant were evaluated and 21 were finally included in this study. Customising communication, different techniques to improve the environment, using technology for familiarisation and distraction have been used in previous studies. The results of this study can be used to make suggestions on how to improve magnetic resonance imaging practice and the autistic patient experience. They can also be used to create training for the healthcare professionals using the magnetic resonance imaging scanners.
The liquid Kangfuxin (KFX) has efficient antifungal activity and can be used in the treatment of vulvovaginal candidiasis in mice

Vulvovaginal candidiasis (VVC) is an infectious disease caused mainly by Candida albicans. Kangfuxin (KFX) is a traditional Chinese medicine preparation made from Periplaneta americana extracts, which promotes wound healing and enhances body immunity and also acts as an antifungal agent. Here, we evaluated the effect of KFX in the treatment of VVC in vitro and in vivo. The minimum inhibitory concentration (MIC50) of KFX against C. albicans ranged from 7·65 to 20·57%. In addition, KFX was more efficient than fluconazole (FLC) in inhibiting the drug‐resistant C. albicans, and the effect was more intense after 8 h. The KFX treatment also exhibited good activity in vivo. It restored the body weight and reduced the vulvovaginal symptoms in mice induced with VVC. It downregulated the expression of the hyphae‐related gene, HWP1, thus inhibiting the growth and development of C. albicans hyphae. It also increased the number of neutrophils and promoted the secretion of interleukin‐17A (IL‐17A); however, the levels of interleukin‐8 (IL‐8) and interleukin‐1β (IL‐1β) decreased in mice with VVC. We deduce that KFX effectively treats vaginal candidiasis in two ways: by inhibiting the growth and development of mycelia to reduce colonization of C. albicans and by promoting the secretion and release of IL‐17A and neutrophils in high numbers to fight C. albicans infection. This study provides a theoretical basis for the use of KFX for the clinical treatment of VVC.
Integrated low‐profile dual loop‐dipole antennas using an embedded electromagnetic bandgap structure

Electrical characteristics of an electromagnetic bandgap (EBG) structure embedded in a high dielectric layer are studied using FDTD simulation methods. A low‐profile loop antenna is designed above the embedded EBG structure. For diversity applications in wireless communications and biotelemetry, a printed dipole antenna is also incorporated with the low‐profile loop antenna. The experimental results of the antennas are compared with the simulated results, to show how applicable embedded EBG structures are for low‐profile antenna designs. © 2007 Wiley Periodicals, Inc.

Looking beyond the Western lens: How culture and identity influence perceptions of empathy in patient‐clinician relationships

Amidst the uncertainty of illness, a doctor’s interaction with patients can make them feel understood and cared for. In a recent Cancer article, Sanders et al explore patients’ perspectives of empathetic provider behavior through a qualitative lens. By capturing patients’ perspectives on empathetic behaviors, medical professionals can mold their interactions with patients to better communicate information, provide comfort, and offer an outlet for complex emotions. In this letter, we seek to build on their study by highlighting perspectives on empathy sometimes seen in immigrant communities or individuals who may not share a Western understanding of the term. Psychology and sociology literature have illustrated that culture plays a major role in shaping our experience with, and expression of, empathy. Perhaps most well studied is the distinction between the Western and East Asian perspectives on the definition of self. Although Western culture emphasizes the individual driven by internal characteristics and preferences, East Asian culture highlights a collectivist sense of self, where one is defined in the context of one’s interdependencies with the community. 4
Iterative modal strain energy method for damage severity estimation using frequency measurements

A damage severity estimation method, named as iterative modal strain energy (IMSE) method, is developed to quantify the damage magnitude using the frequency measurements. Although all existing damage quantification methods that utilize modal strain energy are either employing mode shapes from the damage structure or under/overestimating the damage severity, the IMSE method is able to estimate the severity accurately, requiring only a few amount of identified modal frequencies from the damaged structure. To demonstrate the capabilities of the developed damage severity estimation algorithm, numerical studies are conducted of a clamped‐free beam based on data generated from finite element models. Both noise‐free and noise‐polluted cases are considered. Furthermore, experimental data from a tested clamped‐free beam are utilized to validate the IMSE method. The results demonstrate that the proposed algorithm is capable of quantifying the damage extent accurately. Copyright © 2011 John Wiley & Sons, Ltd.
A square-rooting voltage-to-frequency converter

A clock-controlled voltage-to-frequency converter in which the output frequency is proportional to the square root of the input voltage is described and a detailed error analysis is presented. Accuracies of about 0.02% of full-scale for the voltage input range from 1 mV to 10 V have been achieved using commercially-available CMOS components in good agreement with theoretical expectations.
Low complexity twiddle factor multiplication with ROM partitioning in FFT processor

Proposed is a low-complexity twiddle factor multiplication structure for fast Fourier transform (FFT). In an FFT implementation, the twiddle factor multiplication requires a large ROM to store the twiddle factors. In the proposed structure, the ROM is partitioned into two small ROMs, whose sum of areas is much smaller than that of the original ROM. The proposed structure requires an additional multiplier, but the multiplier is shown to be small in the experimental results. The results show that the proposed structure reduces the area of the twiddle factor multiplication by around 30% with a marginal degradation in SQNR performance.
Methodology to interpolate and extrapolate SAR measurements in a volume in dosimetric experiment

There has been an explosive growth in the area of wireless communication. Over the world, hundreds of millions of subscribers are using mobile phones. International and national organizations have recommended limits for the protection of mobile phone users and standards are going to be established to certify the compliance of mobile phones with these limits. To ensure this conformity, numerical and experimental dosimetric analyzes are essential to evaluate the electric fields inside the user's head. These fields can not be measured near the mobile phone- the phantom interferes where they are a maximum and the use of interpolation and extrapolation is then necessary to evaluate the electric field components. This paper describes the interpolation and extrapolation methodologies, of the experimental sampled data in three dimensions, of the power absorbed in the whole volume of the head phantom. A new method to interpolate and extrapolate SAR measurements is presented. This technique, which is very fast and not very expensive in terms of required memory, is compared with other interpolation techniques which use splines or wavelets.
