Car suspension system monitoring under road conditions (2017)

The paper describes an advanced gyro-based measuring system comprising a CGV-4K central vertical gyro and a G-3M gyrocompass. The advanced system provides additional functions that help measure unsprung mass rotation angles about a vertical axis, rolling angles, trim angles and movements of the unsprung masses of the front (ap and al) and rear b axes when a car wheel hits a single obstruction. The paper also describes the operation of the system, which measures movements of unsprung masses about the body of a car when it hits a single obstruction. The paper presents the dependency diagrams ap = f(t) and al = f(t) for front and rear wheels respectively, as well as b = f(t) for a rear left wheel, which were determined experimentally. Test results for a car equipped with an advanced gyro-based measuring system moving around a circle can form a basis for developing a mathematical model of the process.
Knee Bracing (1994)

The authors present an overview of the design and functional features of knee braces and their relationship to knee biomechanics. Four types of knee braces-prophylactic, rehabilitative, functional, and patellofemoral-have been developed to cover the wide variety of indications in patients who have suffered knee injuries or hope to prevent them. Important considerations when choosing specific brace types are discussed, and summaries of relevant research are presented. Clinical criteria for brace selection are offered to help physicians and sports medicine professionals in choosing the right brace for each patient.
ResGRUA Model for Tool Wear Prediction Based on Encoder-Decoder (2020)

Tool wear prediction is crucial to ensure machine parts quality and machining efficiency. Many machine learning methods, especially deep learning, have been applied to the researches of tool wear intelligent prediction. Aiming at the problems of poor adaptability and low long-term prediction accuracy in traditional tool wear prediction methods, based on encoder-decoder framework, we combine residual GRU network and self-attention, proposing the ResGRUA model to realize intelligent prediction of tool wear. Firstly, features from the input time series are extracted. Then, feature encoder based on bidirectional LSTM network is designed and applied on the generated feature vectors to learn the dynamic laws of two directions. The ResGRUA network as the model decoder is finally trained to predict machine condition. Experimental studies on an open source dataset are performed to validate the effectiveness and superiority of the proposed model. Meanwhile, the experimental results demonstrate that this method has high stability in training process and can predict tool wear more accurately.
Future biogeochemical forcing in Eastern Siberia: cooling or warming? (2014)

Abstract. Over-proportional warming in the northern high latitudes, and large carbon stocks in boreal and (sub)arctic ecosystems have raised concerns as to whether substantial positive climate feedbacks from biogeochemical process responses should be expected. Such feedbacks occur if increasing temperatures lead to e.g., a net release of CO2 or CH4. However, temperature-enhanced emissions of biogenic volatile organic compounds (BVOC) have been shown to contribute to a cooling feedback via growth of secondary organic aerosol (SOA), and related aerosol forcings. Combining measurements in Eastern Siberia with model-based estimates of vegetation and permafrost dynamics, BVOC emissions and aerosol growth, we show here that the additional climate forcing from changes in ecosystem CO2 balance and BVOC-SOA interactions nearly cancel on a regional scale. The interactions between emissions and vegetation dynamics that underlie individual forcing estimates are complex and highlight the importance of addressing ecosystem-climate feedbacks in consistent, process-based model frameworks that account for a multitude of system processes.

Interior noise considerations for advanced high-speed turboprop aircraft (1982)

This paper describes recent research on noise generated by high-speed propellers, on noise transmission through acoustically treated aircraft sidewalls and on subjective response to simulated turboprop noise. Propeller noise discussion focuses on theoretical prediction methods for complex blade shapes designed for low noise at Mach = 0.8 flight and on comparisons with experimental test results. Noise transmission experiments using a 168 cm. diameter aircraft fuselage model and scaled heavy-double-wall treatments indicate that the treatments perform well and that the predictions are usually conservative. Studies of subjective comfort response in an anechoic environment are described for noise signatures having combinations of broadband and propeller-type tone components.
Loss of heterozygosity of multiple tumor suppressor genes in human gastric cancers by polymerase chain reaction. (1996)

Loss of heterozygosity (LOH) occurring on various chromosomes has been described in the majority of human tumors and its targets are believed to be tumor suppressor genes. Although allelic deletion of the p53 gene (over 60%) has been frequently observed in gastric cancer, as well as in other human malignancies, LOH of other tumor suppressor genes is still discrepant in gastric cancer. To our knowledge, simultaneous analysis of LOH using PCR in adenomatous polyposis coli (APC), deleted in colon cancer (DCC), and retinoblastoma susceptibility (Rb) genes has not yet been reported in sporadic gastric cancer. We examined 21 advanced gastric cancers (12 intestinal type and 9 diffuse type) for LOH at the APC, DCC, and Rb loci using PCR. Inclusion of these tumor suppressor genes in the allelic deletions was directly ascertained by performing PCR at polymorphic sites within the genes. LOH occurred in 30% of informative cases at APC, in 27% of informative cases at DCC, and in 30% of informative cases at Rb. Thirty-three percent of tumors informative at all loci (fully informative) lost heterozygosity at all three loci. There were no significant differences among histologic types in the prevalence of LOH at any locus and no correlations between losses involving APC, DCC, and Rb genes. These data suggest that inactivation of APC, DCC, and Rb is involved in the development and progression of some human gastric cancers regardless of histologic type.

The extract on usual purification, furnished 3.2g (80°%.) of 1-chloro, 6-methoxy, 1,2,3,4 tetrahydro naphthalene-2-aldehyde(II)+2
Sewer defect detection and classification using a neural network (2000)

The standard sewer inspection technique, based on closed-circuit television systems, is limited in its performance. It only acquires data from the gaseous part of sewers while the bottom area of the pipe where the sewage is transported is difficult to inspect with existing techniques. Relying on camera data only is not sufficient and may lead to catastrophic events such as sewer collapse. In order to improve the knowledge about the sewer status, a hybrid approach is suggested which complements the existing inspection technique for the acquisition of additional data from the pipe wall below sewage. The paper proposes an inspection system, which makes use of an ultrasonic sensor and a neural network to interpret the acquired sensor signals. The use of the proposed network will remove the need for human operators and minimise the impact of human error and concentration lapses that are common during manual inspection. The network's task is not only to detect sewer defects but also to determine their location in the inner wall of the inspected sewer segment. Experimental set-up, network structure and training as well as initial results using this underwater ultrasonic inspection system in a sewer environment are presented. (13 References).

Ergodic Control and Polyhedral Approaches to PageRank Optimization (2012)

We study a general class of PageRank optimization problems which involve finding an optimal outlink strategy for a web site subject to design constraints. We consider both a continuous problem, in which one can choose the intensity of a link, and a discrete one, in which in each page, there are obligatory links, facultative links and forbidden links. We show that the continuous problem, as well as its discrete variant when there are no constraints coupling different pages, can both be modeled by constrained Markov decision processes with ergodic reward, in which the webmaster determines the transition probabilities of websurfers. Although the number of actions turns out to be exponential, we show that an associated polytope of transition measures has a concise representation, from which we deduce that the continuous problem is solvable in polynomial time, and that the same is true for the discrete problem when there are no coupling constraints. We also provide efficient algorithms, adapted to very large networks. Then, we investigate the qualitative features of optimal outlink strategies, and identify in particular assumptions under which there exists a “master” page to which all controlled pages should point. We report numerical results on fragments of the real web graph.
An efficient minimum area spacing algorithm for noise reduction (2004)

With high clock frequencies, faster transistor rise/fall time, long signal wires, the use of wider wires and Cu material interconnects, the decreased spacing between adjacent wires, and the increased aspect ratio, the crosstalk noise is becoming an important design metric in digital circuits. For a risk-free layout solution of a chip, capacitive and inductive noises should be considered at various routing process stages. A formulation and efficient solution for the min-area spacing problem to satisfy maximum reliability in multiple coupled nets is provided. The noise model used can handle different wire widths, different spacing among wires, and different wire lengths. Experimental results show that the proposed framework redistributes the spacing among neighboring wires to achieve maximum reliability through the minimization of the maximum crosstalk noise in nets.
Measurement-based approach to entanglement generation in coupled quantum dots (2009)

The remarkable phenomenon of measurement-induced quantum entanglement has recently been demonstrated between noninteracting atomic systems [D. L. Moehring et al., Nature (London) 449, 68 (2007)]. In the solid state, the technique may offer a new means of harnessing the strong interactions between neighboring units without the need for precise control over interactions. Recently, we proposed a method for optical parity measurements in a coupled quantum dot system [A. Kolli et al., Phys. Rev. Lett. 97, 250504 (2006)]. Here we perform a comprehensive analytic and numerical study to determine the feasibility of realizing this method using existing technology. We calculate the effects of possible error sources including nonideal photon detectors, ineffective spin-selective excitation, and dot distinguishability (both spatial and spectral). Furthermore, we present an experimental approach for verifying the success of the parity measurement. We conclude that experimental realization of the process should be feasible immediately.
Adaptive beamforming for low-angle target tracking under multipath interference (2014)

Angle of arrival estimation of a low-altitude target over the sea surface is a difficult problem due to the multipath coherent interference from the image target. We present a new monopulse technique utilizing an iterative interference cancellation algorithm based on the array antenna structure to overcome performance degradation. Our algorithm is compared with the maximum likelihood estimator, as well as with the existing algorithm employing the specular reflected error finding function.

Regulatory Considerations in the Design and Manufacturing of Implantable 3D‐Printed Medical Devices (2015)

Three-dimensional (3D) printing, or additive manufacturing, technology has rapidly penetrated the medical device industry over the past several years, and innovative groups have harnessed it to create devices with unique composition, structure, and customizability. These distinctive capabilities afforded by 3D printing have introduced new regulatory challenges. The customizability of 3D-printed devices introduces new complexities when drafting a design control model for FDA consideration of market approval. The customizability and unique build processes of 3D-printed medical devices pose unique challenges in meeting regulatory standards related to the manufacturing quality assurance. Consistent material powder properties and optimal printing parameters such as build orientation and laser power must be addressed and communicated to the FDA to ensure a quality build. Postprinting considerations unique to 3D-printed devices, such as cleaning, finishing and sterilization are also discussed. In this manuscript we illustrate how such regulatory hurdles can be navigated by discussing our experience with our group's 3D-printed bioresorbable implantable device.
Acoustical measurements of bubble production by spilling breakers (1990)

The surface bubble spectral density of newly created bubbles has been measured under spilling breakers in a laboratory facility. This has been accomplished acoustically by passively identifying the radius, position, and time of creation of several hundred individual bubbles as their shock-excited pulsations radiate damped spherical waves of sound. The measured bubble spectrum ranges from radius 50 μm to 7.4 mm with a peak of 6 bubbles per square meter in a 1-μs-radius increment at radius 150 μs. The rate of bubble production has an exponential fall-off with time and 97% of the bubbles are produced in the first 500 ms after the breaker passes. The results supplement recent ocean data for low sea states.
Audio-tactile cues from an object’s fall change estimates of one’s body height (2018)

When we drop an object from our hands, we use internal models of both our body height and object-motion to predict when it will hit the floor. What happens if the sensory feedback finally received from the impact conflicts with this prediction? The present study shows that such conflict results in changes in the internal estimates of our body height: When the object people dropped takes longer than expected to hit the floor, they report feeling taller and behave as if their legs were longer. This provides the first evidence of cross-modal recalibration of body-height representations as a function of changes in the distant environment. Crucially, the recalibration results from a mismatch between the predicted and actual outcome of an action, the ball's release and impact, which are causally-related but separated in space and time. These results suggest that implicit models of object-motion can interact with implicit and explicit models of one's body height.
A Role for Voltage-Dependent Anion Channel Vdac1 in Polyglutamine-Mediated Neuronal Cell Death (2007)

Expansion of trinucleotide repeats in coding and non-coding regions of genes is associated with sixteen neurodegenerative disorders. However, the molecular effects that lead to neurodegeneration have remained elusive. We have explored the role of transcriptional dysregulation by TATA-box binding protein (TBP) containing an expanded polyglutamine stretch in a mouse neuronal cell culture based model. We find that mouse neuronal cells expressing a variant of human TBP harboring an abnormally expanded polyQ tract not only form intranuclear aggregates, but also show transcription dysregulation of the voltage dependent anion channel, Vdac1, increased cytochrome c release from the mitochondria and upregulation of genes involved in localized neuronal translation. On the other hand, unfolded protein response seemed to be unaffected. Consistent with an increased transcriptional effect, we observe an elevated promoter occupancy by TBP in vivo in TATA containing and TATA-less promoters of differentially expressed genes. Our study suggests a link between transcriptional dysfunction and cell death in trinucleotide repeat mediated neuronal dysfunction through voltage dependent anion channel, Vdac1, which has been recently recognized as a critical determinant of cell death.
Combining the Sterile Insect Technique with the Incompatible Insect Technique: I-Impact of Wolbachia Infection on the Fitness of Triple- and Double-Infected Strains of Aedes albopictus (2015)

The mosquito species Aedes albopictus is a major vector of the human diseases dengue and chikungunya. Due to the lack of efficient and sustainable methods to control this mosquito species, there is an increasing interest in developing and applying the sterile insect technique (SIT) and the incompatible insect technique (IIT), separately or in combination, as population suppression approaches. Ae. albopictus is naturally double-infected with two Wolbachia strains, wAlbA and wAlbB. A new triple Wolbachia-infected strain (i.e., a strain infected with wAlbA, wAlbB, and wPip), known as HC and expressing strong cytoplasmic incompatibility (CI) in appropriate matings, was recently developed. In the present study, we compared several fitness traits of three Ae. albopictus strains (triple-infected, double-infected and uninfected), all of which were of the same genetic background ("Guangzhou City, China") and were reared under the same conditions. Investigation of egg-hatching rate, survival of pupae and adults, sex ratio, duration of larval stages (development time from L1 to pupation), time to emergence (development time from L1 to adult emergence), wing length, female fecundity and adult longevity indicated that the presence of Wolbachia had only a minimal effect on host fitness. Based on this evidence, the HC strain is currently under consideration for mass rearing and application in a combined SIT-IIT strategy to control natural populations of Ae. albopictus in mainland China.
