Immune Gene Data-based Molecular Subtyping of Rectal Adenocarcinoma Related to Prognosis

Background: The morbidity and mortality of rectal adenocarcinoma (READ) is increasing, which is considered as an aggressive type of colorectal malignancy. A great deal of evidence has suggested the significant association between the progression of READ and the immunophenotype of tumor cells (i.e. the expression of intracellular immune-related genes). Methods: Samples retrieved from the TCGA and ImmPort database were investigated to identify immune-related genes specifically impacting the prognosis of READ patients. Several typical ones were then selected to construct the prognostic prediction model of READ patients through Lasso algorithm. The training and test cohorts were incorporated into the model, respectively. We stratified READ patients to evaluate the accuracy, efficiency and stability of the model in the prediction and classification of patient prognosis according to the value of median RiskScore (Risk-H and Risk-L). GO and KEGG signaling pathway enrichment analysis were conducted among the nine selected immune-related genes.Results: A total of 57 immune-related displaying marked correlated with patient prognosis were identified and nine most typical genes could be majorly enriched into several pathways with close correlation with READ and the corresponding immune response. the distribution of nine immune-related genes were examined in the samples from both Risk-H and –L groups. Finally, the connection of the RiskScore value with the clinical characteristics of sample and the related signaling pathways were investigated.Conclusions: The prognostic prediction model of RiskScore constructed based on the expression profiling of the nine immune-associated genes exhibited high prediction accuracy and stability to identify the relevant immune features. This model could contribute to the guidance for clinicians in diagnosing and predicting the prognosis for various immunophenotypes. Meanwhile, it also can offer various therapeutic targets for precise treatment of READ in clinical practice according to the identified immune molecules specific to different subtypes.
Performance comparison of control schemes for variable-speed wind turbines

We analyze the performance of different control schemes when applied to the regulation problem of a variable-speed representative wind turbine. In particular, we formulate and compare a wind-scheduled PID, a LQR controller and a novel adaptive non-linear model predictive controller, equipped with observers of the tower states and wind. The simulations include gusts and turbulent winds of varying intensity in nominal as well as off-design operating conditions. The experiments highlight the possible advantages of model-based non-linear control strategies.
AN EXPERIMENTAL INVESTIGATION ON EFFICIENCY IMPROVEMENT OF A CONVENTIONAL KEROSENE PRESSURE STOVE

This paper reports an experimental study dealing with the enhancement of thermal efficiency of a conventional kerosene pressure stove by incorporating a ceramic heat shield and a porous radiant insert. The heat shield was made of a low conducting and radiating alumina Al2O3, while the porous radiant insert was made of highly conducting and radiating ZrO2. The insert was placed in the combustion zone of the stove to have an increased heat transfer by utilizing the concept of the porous media combustion partially. The effects of various parameters, such as the distance between the burner surface and the bottom of the vessel, the vessel diameter, and the fuel flow rate on thermal efficiency, were investigated. For the chosen burner geometry, for a particular size of the vessel and flow rate range, the thermal efficiency was found to be considerably high. Against 55% efficiency of the conventional stoves, for the present configuration, this was found to be 70%.
Improvement of a Social Gaming Checkout User Interface

Social games are utilizing virtual currency to increase the gaming experience as well as their bottom line. Users must progress through a checkout user interface in order to obtain this virtual currency, and the onus is placed on the development team, including the user researcher, to optimize this interface. Playfish recently performed testing on a new version of its checkout interface in one of its social games, Pet Society. It explored the usability and security of the interface, as well as the degree to which the interface integrated with Facebook’s checkout interface. While current spenders rated security quite low due to past personal and second-hand experiences, non-spenders’ ratings were not yet sullied by a negative checkout experience. Therefore, improvement to the interface, particularly in the security domain, has the ability to increase new users’ perceptions when purchasing virtual currency, which may increase the number of microtransactions moving forward.
DEVELOPMENT OF BIO-IMPLANTED MICRO-SYSTEM WITH SELF-RECOVERY ASK DEMODULATOR FOR TRANSCUTANEOUS APPLICATIONS

This paper deals with the development of bio-implanted micro-system with low-power and high data rate based on amplitude shift keying (ASK) modulation technique to stimulate nerves and muscles. The modified system is operated by a low-frequency band 13.56 MHz according to the industrial-scientific-medical (ISM) bands to avoid the biological tissue damage. The data rate on the demodulator side is from 1 Mb/s and up to 1.5 Mb/s depending of generating binary signal (TBIT = 1 μs or 0.5 μs) with modulation index of 13% and modulation rate 7.3%, 9% and 11%, respectively. The proposed inductive coupling link achieves 73% of link efficiency. The modified rectifier with self-threshold voltage cancellation techniques and voltage regulator without thermal protection circuit and without passive elements occupies small area that is modified to generate adequate and stable DC voltages of 1.8 V. A new ASK demodulator structure based on two comparators is developed to extract a synchronized demodulated signal with minimum error. Thereby no need for clock recovery circuit and delay-locked loops (DLL) circuits for data synchronization at 1 Mb/s and 1.250 Mb/s of speed. The system designed using OrCAD Pspice 16.2 is based on 0.35 μm technologies.
Industrial Applications of Automatic Optical Inspection (A European Point of View)

The automation of production technology has made great strides through use of program controlled production machines, material transport and manipulation systems. It is for that reason that quality assurance plays a key role in modern flexible manufacturing systems. Inspection systems evolved that automated work actually done by inspection personnel. This field embraces tasks which require the human senses sight and touch, and at times place high demands on the decision capability. Hence, electro-optical systems, and here especially vision systems, hold the key to the development of automated factories - their integration will greatly influence and accelerate the advance of automation.
EFFECTS OF FOLIAGE DENSITY AND GROUND SPEED ON ULTRASONIC MEASUREMENT OF CITRUS TREE VOLUME

Ultrasonic sensors can be used to quantify and map tree canopy volume, which is useful for planning site-specific management practices within a grove and estimating crop yield. An experiment was conducted to examine the effects of the canopy foliage density and ground speed on the performance of the Durand-Wayland ultrasonic system in tree volume measurement. Fifteen densely foliated (dense) and 15 partially defoliated (light) citrus trees were scanned from both sides at three ground speeds in three replications. The measurements were compared to those calculated from manual measurements of the tree dimensions. The difference between ultrasonic and manual volumes was used to evaluate the performance of the ultrasonic system. The difference between ultrasonic and manual volumes ranged from –17.3% to 28.71% at the 95% confidence level. Ninety five percent of the ultrasonic measurements were repeatable within –12.7% to 30.9% of the manual volume. Canopy foliage density had significant effect on ultrasonic measurements of canopy volume. The volume difference was higher in light than dense trees. There was no significant effect of ground speed (1.6 to 4.7 km/h) on ultrasonic volume measurements. Variability of the measurements in partially defoliated canopies increased as ground speed increased. There was a significant difference between the volumes of two sides of the trees.
A review of rectenna models for electromagnetic energy harvesting

Purpose – Distributed wireless sensor networks (DWSNs) are applied in a variety of applications that can enhance the quality of human life. Batteries are the predominant source of energy in DWSNs. One of the key obstacles in the adoption of DWSNs technology is the limited lifetime of batteries in microsensors. Recharging or replacing depleted batteries can significantly increase costs in DWSNs. The purpose of this paper is to address, through a thorough review, this power challenge in DWSNs and to evaluate a 16‐element equiangular spiral rectenna to harvest ambient microwave energy in real‐life scenarios to supply indoor DWSNs.Design/methodology/approach – The paper focuses on the practical implementation of a rectenna that can be used in electromagnetic energy harvesting.

A Simple Compact Microstrip Wideband Bandpass Filter

Two wideband bandpass filters with miniature size and wide stopband are proposed by using cascaded U-shaped resonators. The filters exhibit bandwidths of 31.1% and 28.8% at about 5.3GHz and 5.6GHz, respectively. Both designed filters have simple structures and compact sizes, wide passband, excellent out-band performance with wide lower and upper stopbands, and a pair of transmission zeros on both sides of passband. The new designs have evident circuit size reduction compared with relative reports. A wideband microstrip BPF is fabricated and measured, and the measurement exhibits good agreement with the prediction.
Fault modeling of electrostatic comb-drives for MEMS

The work described in this paper is aimed at fault modeling and fault simulation of electrostatic comb-drives. At present, we have taken into account the most typical defects which we have encountered through fabrication of resonator test structures. These defects include stiction of the suspended beams to the substrate surface and the break of comb-drive model, and the impact of a faulty comb-drive is assessed for different resonator-based designs.
Image-Based Simulation for Snowy Scenes

In this paper, we propose an image-based approach for the simulation of outdoor snowy scenes. Using a snowy image as the reference, we extract the snow covered regions from the reference through a snow model and achieve the snow color information. Then the target image will get the snow color information and take on snowy appearance through a color transfer procedure. To solve the problem of different data distributions between the reference and the target in the procedure, power transform and modulus transform are employed to adjust the image data according to the snow information derived from the reference image data. The experimental results indicate this approach can simulate the snowy scenes with high quality while greatly reducing the computational complexity of simulation compared with the traditional algorithms.
Heavy Timber Decks on Steel Beam Bridges

Delaware County, NY owns approximately 270 bridges and 130 major culverts (greater than 1.5 m (5 ft) long) and performs bridge design, maintenance and replacement with an experienced Department of Public Works’ staff. The County is located in rural upstate New York and is larger in area than Rhode Island. Many of its bridges have relatively low traffic counts, yet are subject to heavy truck loading due to its agricultural, logging, and mining industries. The most common type of superstructure in the County is comprised of longitudinal steel beams (nearly 50% of the total). Deck types include traditional reinforced concrete, transverse corrugated steel pans with asphalt fill, open metal grid decks, and timber (about 15% of the total). Over the past 25 years, the use of timber at DCDPW as a deck material has evolved from nail laminated 50 mm (2 in) nominal thick boards on edge to transverse glu-laminated deck panels to heavy timbers (150 mm x 200 mm (6 in x 8 in) ). Many variations have been tried and details have evolved for construction, connections, and protection. This presentation will include highlights of the evolution of preferences based on engineering, availability, constructability, construction duration, durability, maintenance experience and costs.
Measuring shape and deformation of small objects using digital holography

Micro-systems engineering is a fast growing technology with a wide variety of different materials. The task to ensure reliability and precision of the products needs the precise knowledge of the materials' properties, which is too less in dimensions smaller than one millimeter at the moment. Because properties determined at much larger specimen cannot be scaled down without any experimental result, simple and robust methods to analyze the materials' shape and deformation under a given load must be developed. Holographic interferometry and optical contouring techniques are widely used as highly sensitive and contactless methods for deformation and shape analysis. To get a full 3d-information of the object's surface, however, requires a complex optical setup with at least three illumination directions. Especially when small objects like micro-components have to be examined, the ordinary use of conventional holography becomes more and more a problem. In that case digital Holography can be used as a fast, simple and robust method. It replaces the classic holographic recording media by a CCD matrix. The whole reconstruction process of the interference phase is done by computer. Compact and very simple setups can be achieved by use of fiber optics. Several experiments realized in an optimized setup by using four illumination directions are presented to show the advantages of digital holography for the investigation of microsystems. This new technique is applied to components with lateral extensions from 0.1 m to 0.001 m to examine their shape and their full three dimensional deformation under a given mechanical load. The results are compared with computer simulations using FEM. For compound Si/Ni microbeams Young's modulus was determined as an example for this technology of measurement.
The Influence of Anodization Time With The Electrochemical Cell Design on The Fabrication Process of Porous Silicon Nanostructures

The influence of anodization time with the electrochemical cell design on the fabrication process of porous silicon (PS) nanostructures based on two electrochemical anodization cells (designed single tank cell and double tank cell) with two anodization times (10 and 30 minutes) was studied. Atomic force Microscopy (AFM) characterization had revealed three types of pores, mesopores, mesopore fill of mesopores, and macropore fill of mesopores were obtained from designed single tank cell with (10 and 30 minutes) of anodization time, whilst for double tank cell has not revealed precise information about the size and type of pores. Pores formation have been further approved by current-voltage (I-V) measurement and photoluminescence emission by ultraviolet-lamp (254-366) nm for both electrochemical cells.
Analysis of Travel Cost Components Using Large-Scale, Dynamic Traffic Models

The original departure-time-choice model introduced by W. Vickrey (1969) for a single origin-destination (O-D) pair is used as a framework for analysis. The aggregation of the commuter’s travel cost for large-scale dynamic networks extends the results obtained by Vickrey for the basic single O-D pair model. A test-site application and a policy example (extension of staggered hours) are provided for the network of the city of Geneva, Switzerland. The focus is on the morning peak hour of private transportation networks.
High Power Factor Light-emitting Diode Driver on Digital Signal Processor Without Electrolytic Capacitor for High-power Lighting

Abstract—Electrolytic capacitor is a key factor that limits the life-time of the driver in a high-power light-emitting diode (LED) lighting. This article presents a high-power LED lighting driver on a digital signal processor without an electrolytic capacitor. The driver is composed of three stage circuits. The first stage is the boost power factor correction converter to achieve a high power factor. As it does not use an electrolytic capacitor, the output voltage ripple is larger, which directly affects the overall performance of the LED driver. Consequently, it must be optimized through the second and third stages. The second stage is the two-output LLC (Double inductance and capacitance) resonant converter, which is driven by a digital signal processor. This stage provides galvanic isolation and reduces voltage. The third stage is the two-input buck converter based on digital signal processor control that reduces the low-frequency ripple generated from the first two stages. Moreover, the regulation of each LED string current is achieved at this stage. The simulation and experimental results show that this LED lighting driver can achieve a high power factor and good constant current characteristics.
Robustness analysis in structural optimization

Structural optimization typically aims at high performance levels for a clearly specified set of conditions. Unfortunately, this goal can usually be achieved only by sacrificing robustness of the design. This implies a high sensitivity with respect to unforeseen stochastic situations or unavoidable random manufacturing tolerances. In order to prevent structural failure due to loss of robustness it is therefore desirable to incorporate a suitable measure of robustness into the optimization process. This can be achieved by introducing additional constraint conditions or appropriate modifications of the objective function. An example for such a design concept is reliability-based optimization based on the notion of the failure probability. This is most appropriate for high-risk structures such as, e.g. power-generating facilities. Alternatively, simpler stochastic measures such as variances or standard deviations might be more appropriate for the design of low-risk structural elements which are frequently found, e.g. in the automotive industry. This paper discusses the basic requirement for robust optimization and attempts to outline the pros and cons of different approaches to the solution of this problem.
Harmonic Reduction in DC-Link Current of a Dual-Inverter Pole-Changing Induction Motor Drive for Electric Vehicles

In electric vehicles, the DC-link current harmonics of the motor drive can seriously affect the battery management device and even the battery life. The purpose of this paper is to analyze the DC-link current of a newly developed dual-inverter pole-changing induction motor drive, and hence to suppress its harmonic contamination. The key is to employ newly the double Fourier series to model the harmonic current in the DC link of the dual inverter, which adopts a special arrangement of space-vector pulse-width modulation. Digital-signal processor-based implementation and experimentation are given to verify the theoretical analysis.
Postural Sway and Foot-Ground Relationship are Significantly Modified by Backpack Carriage during Upright Stance: A Study on Primary School Children

School is a person's first workplace and, from the age of six, children experience activities such as lifting, pulling and carrying a load (typically in the form of a backpack) which often represents an important percentage of their body weight. Among the possible consequences originated by back overload we have balance impairment and altered plantar pressure distribution, which however have been scarcely explored in children. On the basis of these considerations, this study intends to assess modifications in sway parameters, foot-ground contact area and pressure distribution introduced by backpack carriage in Italian primary school children. Two 30-second trials (with and without backpack) were performed directly at a school on a regular school day to collect data on sway area, centre of pressure path length, maximum displacement range in Antero-Posterior and Medio-Lateral directions, foot-ground contact area and pressure distribution. The results show a significant load-induced increase in all sway parameters and the existence of a linear relationship between sway area and backpack weight. Contact area also varies linearly with load and peak pressure values are significantly altered by the presence of a backpack in midfoot and forefoot, with increases up to 30%. These findings, together with the fact that about half the children carry a load exceeding 15% of their body weight, suggest that concern about severe postural alterations associated with carriage of overweight backpacks, remains justified.
Laparoscopic Single Figure of Eight Suturing Omentopexy for the Treatment of a Perforated Duodenal Ulcer

Purpose Safe and effective surgical treatment of peptic ulcer perforations is fundamental to achieve favorable outcomes. We present laparoscopic single figure of eight suturing omentopexy for perforated duodenal ulcer and review associated clinical outcomes. This is a new formulaic surgical technique for laparoscopic omentopexy. Methods Laparoscopic single figure of eight suturing omentopexies for perforated duodenal ulcer were completed in 15 consecutive patients between April 2008 and November 2017 at Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, Seoul, Korea. Using prospectively collected data, we performed an observational study on an intention-to-treat basis. Results The mean age of the 15 patients who underwent laparoscopic repair was 41.7±13.9 years. The perforation site was the anterior duodenal bulb in all patients. The median perforation size was 5 mm (range: 3~8 mm). The mean operation time was 66.7±19.6 minutes. There was no evidence of leakage from the omentopexy site clinically or in the postoperative upper gastrointestinal series. One patient (6.7%) experienced the postoperative complication of pneumothorax. There were no cases of postoperative mortality or reoperation within 30 days after surgery. The median time to tolerance of regular diet was 6 (range: 4~9) days. The median postoperative hospital stay was 7 days (range: 5~11 days). Conclusion Laparoscopic single figure of eight suturing omentopexy can be a viable option in the surgical management of perforated duodenal ulcer in selected patients without surgical risk factors. Laparoscopic single figure of eight suturing omentopexy is safe and easy to perform, and may therefore reduce operation time.
