Toward a High-Performance and Low-Loss Clos–Benes-Based Optical Network-on-Chip Architecture

As chip multiprocessors (CMPs) keep growing in capability, on-chip communication efficiency is crucial to the overall performance. However, on-chip networks based on electronic switches suffer from excessive power consumption and limited performance. In order to take advantages of optical interconnect, we propose an optimized design toward a high-performance and low-loss Clos–Benes-based hierarchical optical network-on-chip (NoC) for large-scale CMPs. We propose several key techniques, including a loss-aware adaptive (LAA) routing for intraswitch Benes network, a priority-based round-Robin virtual output queue selection and a $Q$ -learning-based heuristic routing for interswitch Clos network, and a local transfer link (LTL) technique to improve the traffic locality. A case study on a 256-core CMP under uniform traffic shows that the network throughput is increased by 346.7%, 61%, and 12.9%, respectively, than the mesh, fattree, and the traditional generic Clos–Benes optical NoC. On average of a set of real applications, the application end-to-end delay is reduced by 47.6%, 28.2%, and 19.4%, respectively, than the mesh, fattree, and the traditional generic Clos–Benes network. Meanwhile, the average optical power loss is decreased by 11.8% and 49.9%, respectively, as compared to the mesh and fattree. As compared to a baseline Clos–Benes network, the use of LAA routing together with the LTL could reduce the average optical power loss by 28.4%.
Effect of Halo Protection Device on the Aerodynamic Performance of Formula Racecar

 Abstract — This paper explores the aerodynamics of the formula racecar when a ‘halo’ driver-protection device is added to the chassis. The halo protection device was introduced at the start of the 2018 racing season as a safety measure against foreign object impacts that a driver may encounter when driving an open-wheel racecar. In the one-year since its introduction, the device has received wide acclaim for protecting the driver on two separate occasions. The benefit of such a safety device certainly cannot be disputed. However, by adding the halo device to a car, it changes the airflow around the vehicle, and most notably, to the engine air-intake and the rear wing. These negative effects in the air supply to the engine, and equally to the downforce created by the rear wing are studied in this paper using numerical technique, and the resulting CFD outputs are presented and discussed. Comparing racecar design prior to and after the introduction of the halo device, it is shown that the design of the air intake and the rear wing has not followed suit since the addition of the halo device. The reduction of engine intake mass flow due to the halo device is computed and presented for various speeds the car may be going. Because of the location of the halo device in relation to the air intake, airflow is directed away from the engine, making the engine perform less than optimal. The reduction is quantified in this paper to show the correspondence to reduce the engine output when compared to a similar car without the halo device. This paper shows that through aerodynamic arguments, the engine in a halo car will not receive unobstructed, clean airflow that a non-halo car does. Another negative effect is on the downforce created by the rear wing. Because the amount of downforce created by the rear wing is influenced by every component that comes before it, when a halo device is added upstream to the rear wing, airflow is obstructed, and less is available for making downforce. This reduction in downforce is especially dramatic as the speed is increased. This paper presents a graph of downforce over a range of speeds for a car with and without the halo device. Acknowledging that although driver safety is paramount, the negative effect of this safety device on the performance of the car should still be well understood so that any possible redesign to mitigate these negative effects can be taken into account in next year’s rules regulation.
Evaluation of the specialist community public health nursing peripatetic assessment model

The Health Visitor Implementation Plan 2011-15: a call to action, called for an additional 4200 health visitors to be trained by 2015. To accommodate larger numbers of students, specialist community public health nursing (SCPHN) programmes across the UK have undergone significant transformation in terms of practice supervision. Somerset Partnership NHS Trust introduced a peripatetic assessment model involving practice teachers and practice mentors. This differed from traditional one-to-one approaches of supervision to one-to-three. Practice teachers mostly supervised students through close collaboration with mentors who worked directly with students on a daily basis. Using a mixed methods approach, the evaluation aimed to assess the effectiveness of the new model from the perspective of SCPHN students, mentors, practice teachers (PTs) and managers. Data were collected through an anonymous online survey and individual interviews or focus groups. Overall, participants were positive about the peripatetic model’s impact on student learning and practice experience, in addition to the general up-skilling of the wider health visiting workforce and possible implications of continuation into the future. Any concerns raised focused on adequate preparation and support for mentors and the need for clear communication and role differentiation between practice teachers and mentors.
Application of Microencapsulated Bamboo Leaf Extract Powder to Control the Rancidity in Moo Yor (Vietnamese-style Sausage) During Refrigerated Storage

Recently, bamboo leaf extract (BLE) is considered as a new source of natural antioxidants. Microencapsulation technique is one of the potential methods to protect bioactive compounds. In this study, a microencapsulated bamboo leaf extract (MBLE) and its ability to prevent lipid oxidation in fat-containing product was investigated. Moo Yor, a Vietnamese-style sausage is one of the short shelf life meat products due to rancidity developed from lipid oxidation during refrigerated storage. A fat-rich Moo Yor, accounted for 14% fat content, was prepared and MBLE was added at 0, 1, 2, and 3% (w/w), comparing with the addition of conventional synthetic antioxidant butylated hydroxytoluene (BHT). All samples were collected every 2 days throughout 8 days of storage at 4°C to investigate the change of phenolic compounds and lipid oxidation. The gradually reduction of lipid oxidation throughout storage in Moo Yor with BHT was higher than those added with 2% MBLE and 1% MBLE except in Moo Yor with 3% MBLE. The remaining of total phenolic compound in Moo Yor samples was increased in the first 2 days and then decreased throughout storage. The decreasing of total phenolic compounds in control was higher than those of Moo Yor with 1% MBLE, 3% MBLE, BHT, and 2% MBLE, respectively. These results implied that 2% MBLE was the most effective antioxidant to prevent rancidity in fat-rich Moo Yor during 8-day storage at 4°C.
Effectiveness of Health Education Family Planning Guidelines on Health Beliefs and Behaviours Regarding Family Planning Methods Among Married Men in Myanmar

Introduction: Males are the most important members and care-takers of the family, but they are considered to be uncooperative when it comes to the usage of family planning methods. Traditionally, family planning programs have focused primarily on women, and most of the methods are designed for women considering that it is the women who become pregnant and it is easy to deliver reproductive health services as part of maternal and child health programs. The main objective of this study was to study the effectiveness of Health Education (HE) Family Planning Guidelines on Health Belief and Behaviours regarding family planning methods among married men Method s : A quasi-experimental study design was used to compare the results of the effectiveness of health education on the health beliefs and behaviours regarding family planning methods among married men. Mann-Whitney test and Manova test were used to analyse the data. Result s : It was found that there was a difference of health belief with p= 0.038, knowledge with p= 0.000 and attitude with p= 0.000 between the treatment and control group. Conclusion : There was an impact on the improvement of health belief and behaviours regarding family planning methods in the study group which was significantly improved after intervention. As the predetermined hypothesis, a difference was found between the knowledge, attitude and health beliefs of the married men who received health education and those who did not receive health education.

1026Background: Constitutive activation of the phosphatidylinositol-3-kinase (PI3K) signaling pathway is a mechanism of trastuzumab resistance in HER2-positive metastatic breast cancer (MBC). Alpelisib (BYL-719) is the first oral PI3K inhibitor that selectively inhibits the PI3Kα isoform. We aimed to determine the maximum tolerated dose (MTD), safety, and activity of alpelisib with ado-trastuzumab emtansine (T-DM1) in HER2-positive MBC that failed standard therapy. Methods: In this phase I study, pts received alpelisib daily (cohort 1: 300 mg, (-1): 250 mg) and T-DM1 3.6 mg/m2 on Day 1 every 21 days using a 3+3 design with dose expansion at MTD. Dose-limiting toxicity (DLT) was defined as CTCAE Grade 3/4 adverse events (AE) during cycle 1. Data cut-off is Jan. 1, 2017. Results: 17 pts were enrolled. Median age was 53 (40-66). Median prior lines of therapy in metastatic setting was 4.5 (0-13) including 9 pts who progressed on prior T-DM1 (after median 8 cycles). Median number of metastatic sites was 2 (1-5.
Assessment of impact of patient’s age at presentation and Pirani score on treatment duration in clubfoot

Background: Delayed presentation of clubfoot is the primary problem in developing nations like India. The purpose of this study was to find out whether the delay in presentation of club feet and its initial Pirani score in infants adversely affect treatment course in terms of number of plaster casts required to achieve complete correction. Methods: We retrospectively studied 2 years record of infants with idiopathic clubfoot treated with the Ponseti method. Karl Pearson correlation coefficient (r) was used to find out correlation of patient`s age in months with number of casts required to achieve full correction. We also used this correlation coefficient to find out correlation between severity score of foot and number of casts needed. Correlation was considered statistically significant if P < 0.05. Results: There was a positive and strong correlation between severity score of foot and number of plaster casts required to achieve full correction and it was statistically significant. We also found a positive but weak correlation between patient`s age in months and number of casts required and the correlation was not found statistically significant. Conclusion: The number of casts required for correction in idiopathic clubfoot in infant was significantly influenced by its initial Pirani score. However, Age at presentation does not have statistically significant impact on number of Ponseti cast required for correction.
Soil quality assessment of vegetation restoration after a large forest fire in Daxing’anling, northeast China

Abstract: Forest fires significantly change soil function and quality. Finding an effective way to accelerate the restoration of soil quality after forest fires is a major issue. This study investigated the soil quality index (SQI) during vegetation restoration after a fire in a Larix gmelinii plantation, throughout different restoration years. Fifteen physical, chemical, and biological properties of soil were examined using principal component analysis, and soil quality was assessed by SQI. The results revealed that soil physical properties, chemical properties, and enzyme activities showed the most improvement after 24 yr of restoration. Soil microbial biomass carbon content and microbial biomass nitrogen content increased with restoration years. Soil bulk density, microbial biomass nitrogen, sucrase, and catalase were retained in the minimum data set. After 24 yr of restoration, SQI was the highest, with a value of 0.52, followed by natural restoration, 21, 13, and 16 yr; the SQI after 3 yr of restoration was the lowest, with a value of 0.26. Artificial regeneration accelerated the recovery of soil quality after 24 yr. Soil quality should be monitored continuously in the study area.
Interpretation of Urban New-type Public Spaces: An Anthropological Case Study of Fang Suo in Guangzhou

Abstract As an urban new-type public space, Fang Suo Commune has become an important place for cultural, leisure and consumption activities of urban residents in the context of mass leisure and postmodern consumption. The existence and development of Fang Suo as a unique space are worthy of in-depth analysis given the fact that physical bookstores are declining. This article interprets the unique combination of spaces of Fang Suo, and analyzes the structure of the space itself, features of different consumer groups and their interactions with the space through observation and interview from an anthropological perspective. It has been found that Fang Suo has the multiple attributes of a cultural space, consumption space and leisure space for its multimode fusion and spatial design, and the spatial consumption behavior of people is making the boundary of space form vague while shaping space form. The social significance shown in space consumption needs further exploration.
Responses of pregnant ewes and young lambs to ovalbumin immunization, antiovalbumin antibody transfer to lambs, and temporal changes in antiovalbumin antibody,

Abstract Factors affecting the decay of maternally derived IgG and ability of neonatal lambs to produce protective amounts of their own IgG are not well understood. Thus, we conducted 3 experiments to quantify the 1) response of pregnant ewes to ovalbumin immunization, 2) antiovalbumin antibody (OV-IgG) transfer to lambs, 3) changes over time in OV-IgG in lambs, and 4) response of young lambs to ovalbumin immunization. In Exp. 1, ewes (n = 10/group) either received control (adjuvant + saline) or ovalbumin (ovalbumin + adjuvant + saline) injections at ≈ 42 and 14 d prepartum. Ovalbumin increased (P < 0.001) ewe serum and colostrum OV-IgG. Serum OV-IgG was greater (P < 0.0001) in lambs from ovalbumin-treated than in lambs from control ewes. In Exp. 2, lambs (n = 20/group), which were from ewes that had received ovalbumin prepartum, were given either control or ovalbumin injections on d 1 and 15 of age. From d 1 to 15, maternally derived OV-IgG was less (P < 0.04) in ovalbumin-treated than in control lambs. After d 15, OV-IgG was greater (P < 0.001) in ovalbumin-treated than in control lambs. In Exp. 3, lambs (n = 20/group), which were from ewes naïve to ovalbumin, received 1 of 4 treatments: 1) d-1 + d-15 control injections; 2) d-1 + d-15 ovalbumin; 3) d-28 + d-42 control; and 4) d-28 + d-42 ovalbumin. In d-1 + d-15 ovalbumin lambs, OV-IgG increased (P < 0.001) from d 7 to 21 after treatment and then decreased (P < 0.004) after d 28. In d-28 + d-42 ovalbumin lambs, OV-IgG increased (P < 0.001) steadily until d 21 after treatment and then stabilized after d 21. At ≈ 159 d of age, lambs in each group received injections consistent with their original type. After the d-159 treatment, ovalbumin injection increased (P < 0.0001) OV-IgG, and the injection type × time interaction was significant (P < 0.0001). In d-28 + d-42 ovalbumin lambs, OV-IgG just before the d-159 injections was greater (P < 0.006) than that in the other groups. In this study, late pregnant ewes produced OV-IgG after ovalbumin injections and then transferred OV-IgG to lambs via colostrum. Ovalbumin treatment of young lambs reduced circulating maternally derived OV-IgG, but it also induced an immune response in the lambs. Overall, our results support recommendations to vaccinate ewes against common pathogens during late pregnancy and to ensure that lambs receive adequate colostrum soon after birth.
Health technology assessment of the different dialysis modalities in Norway

bled in Norway. After a request from The Norwegian Directorate of Health we performed a Health Technology Assessment comparing effi cacy, safety and costeffectiveness of different dialysis modalities. Clinical fi ndings: •No signifi cant differences in mortality, in quality of life or in infections. •Signifi cantly fewer hospitalisation days per patients per year in the hemodialysis hospital group versus the peritoneal dialysis at home group. Economic evaluation: •In our model analyses all dialysis modalities were almost equally effective. •Hemodialysis at home was the most effective and cost-effective alternative compared to all other hemodialysis modalities from both healthcare and societal perspectives. •Peritoneal dialysis was the least costly, and hence the most cost-effective alternative compared to all hemodialysis modalities. •The results of our sensitivity analysis showed that cost data had the greatest impact on the results’ uncertainty.

Efficient Inference of Image Objects using Semantic Segmentation

In this paper, we propose an efficient object classification method based on semantic segmentation for multi-labeled image data. In addition to various pixel unit information and processing techniques such as color information, contour, contrast, and saturation included in image data, a detailed region in which each object is located is extracted as a meaningful unit and the experiment is conducted to reflect the result in the inference. We use a neural network that has been proven to perform well in image classification to understand which object is located where image data containing various class objects are located. Based on these researches, we aim to provide artificial intelligence services that can classify real-time detailed areas of complex images containing various objects in the future.

Sawtooth-Carrier-Based Pulsewidth Modulation Method for Quasi-Z-Source Inverter With Zero-Voltage-Switching Operation to Reduce Harmonic Distortion and Inductor Current Ripple

This article proposes a novel sawtooth-carrier based pulsewidth-modulation (SCPWM) method for quasi-Z-source inverter (qZSI) with the zero-voltage-switching (ZVS) operation to reduce the total harmonic distortion (THD) and inductor current ripple. The conventional variable-duty pulsewidth-modulation (VDPWM) method has been being used for qZSIs because it causes the low switching loss. However, this method has the limitation not only to improve the THD of output current but also to reduce the size of inductor when it is applied to the qZSI. To figure it out, the proposed SCPWM method uses the sawtooth-carrier signal while keeping the benefit from the use of variable duty. In particular, the ZVS operation occurs whenever the edge of sawtooth-carrier signal is located in the time interval of shoot-through state. This allows to increase the carrier frequency of qZSI without any additional switching loss. Thus, both the THD of output current and the inductor current ripple can be reduced while keeping the high efficiency of system. The operating principle of the proposed SCPWM method is first explained in detail. Thereafter, its performance is mathematically analyzed and compared with that of conventional VDPWM method. Finally, its practical effectiveness is verified by the hardware experimental test.
Cognitive Load and Situation Awareness for Soldiers: Using an Auditory Detection Response Task

We examined the cognitive load and situation awareness of tactical decision makers processing information with a battle management system. We presented information in visual and auditory form. To measure workload, we used an auditory detection response task (DRT). We found that DRT performance was worse with faster message presentation and with auditory presentation, indicating greater workload in those conditions. We also found that situation awareness was lower with faster presentation. However, we found that auditory presentation produced greater situation awareness than visual presentation. These results are partially consistent with results of a previous study (Hollands, Spivak, & Kramkowski, in press), but suggest that workload and situation awareness can sometimes diverge.
A comparative study of postoperative chronic pain after tension free inguinal hernia repair using absorbable versus non absorbable sutures for mesh fixation

Inguinal hernia is a one of common diagnosis which is frequently encountered in routine clinical practice. The Lichtenstein technique (tension free mesh repair) is currently the gold standard in open inguinal hernia repair. The Lichtenstein repair has reduced the incidence of recurrent inguinal hernia. Currently chronic groin pain (Inguinodynia) is one of the common complications after hernia repair and it may affect quality of life. Chronic groin pain has been reported in 16% to 62% of the patients. It should be differentiate with early postoperative pain. According to International Association for the Study of Pain (IASP), chronic groin pain is defined as “groin pain as any VAS (visual analogue scale) score above zero which lasts for more than 3months following inguinal hernia repair”. Cutoff point to differentiate post operative pain and chronic groin pain is 3 months as per major consensus. It may be continuous as described by patients as an ongoing awareness of pain or it may be activity related pain occurring only during activity like cycling, running, ABSTRACT
Architectures of high-performance VLSI for custom computing systems

The article deals with the design of specialized VLSI designed for the construction of high-performance computing systems. Common options for building such systems are general-purpose processors (CPUs), graphics accelerators (GPUs) that work in the mode of general-purpose computing acceleration, and FPGAs that are configured to implement a specific task or a narrow class of tasks. If there is a demanded class of tasks with specific requirements for computing resources, it is possible to develop a specialized VLSI that is more effective than CPU and GPU in terms of the use of crystal resources, and more productive than FPGA due to the use of hardware-implemented connections instead of programmable cells and switched trace lines. Taking into account modern trends in microelectronics and existing technological lag from leading global manufacturers, an important role is played by the choice of VLSI architecture as well as the use of architectural and circuit design solutions that reduce technical risks and provide solutions to urgent problems for Russian companies.
