Session 15 overview: Low-power processors &#x00026; communication (2010)

Tomorrow's smart-phones will need to support multiple GHz instruction rates for their application processing, and well over 100Mb/s data rates on their cellular communication links. For all the digital processing involved, only about 1W of battery power is available. In this session we highlight a number of milestones towards these challenging goals.
Amniotic Fluid Glycine-Valine Ratio and Neonatal Morbidity in Fetal Growth Restriction (1997)

Amniotic fluid glycine-valine ratio is elevated in growth-restricted fetuses compared with control fetuses. However, the level of glycine-valine elevation is not associated with neonatal morbidity related to hypoglycemia, arterial cord blood gas abnormalities, or birth weight percentile.
Data-Driven Transit Network Design From Mobile Phone Trajectories (2016)

This paper presents a data-driven method for transit network design that relies on a large sample of user location data available from mobile phone telecommunication networks. Such data provide opportunistic sensing and the means for transit operators to match supply with mobility demand inferred from mobile phone locations. In contrast to previous methods of transit network design, the proposed method is entirely data driven, leveraging the large-sample properties of disaggregate mobile phone network data and mobility pattern mining. The method works by deriving frequent patterns of movements from anonymized mobile phone location data and merging them to generate candidate route designs. Additional routines for optimal route selection and service frequency setting are then employed to select a network configuration made up of routes that maximizes systemwide traveler utility. Using data from half a million mobile phone users in Abidjan from the telco operator Orange, we demonstrated to provide resource-neutral system improvement of 27% in terms of end-user journey times.
MATCHCLIP: locate precise breakpoints for copy number variation using CIGAR string by matching soft clipped reads (2013)

Copy number variations (CNVs) are associated with many complex diseases. Next generation sequencing data enable one to identify precise CNV breakpoints to better under the underlying molecular mechanisms and to design more efficient assays. Using the CIGAR strings of the reads, we develop a method that can identify the exact CNV breakpoints, and in cases when the breakpoints are in a repeated region, the method reports a range where the breakpoints can slide. Our method identifies the breakpoints of a CNV using both the positions and CIGAR strings of the reads that cover breakpoints of a CNV. A read with a long soft clipped part (denoted as S in CIGAR) at its 3'(right) end can be used to identify the 5'(left)-side of the breakpoints, and a read with a long S part at the 5' end can be used to identify the breakpoint at the 3'-side. To ensure both types of reads cover the same CNV, we require the overlapped common string to include both of the soft clipped parts. When a CNV starts and ends in the same repeated regions, its breakpoints are not unique, in which case our method reports the left most positions for the breakpoints and a range within which the breakpoints can be incremented without changing the variant sequence. We have implemented the methods in a C++ package intended for the current Illumina Miseq and Hiseq platforms for both whole genome and exon-sequencing. Our simulation studies have shown that our method compares favorably with other similar methods in terms of true discovery rate, false positive rate and breakpoint accuracy. Our results from a real application have shown that the detected CNVs are consistent with zygosity and read depth information. The software package is available at http://statgene.med.upenn.edu/softprog.html.
Time course of changes in sperm morphometry and semen variables during testosterone-induced suppression of human spermatogenesis (2005)

Sperm concentration, total count, motility and morphometry exhibited similar average decay rates (5 day half-life). The mean delay to onset of decline in concentration was 15 (IM-T) and 18 (T-implant) days. The significantly longer (P < 0.005) delays deduced for the commencement of fall in normal morphology (41 days), normal morphometry (40 days) and sperm viability (43 and 55 days), and the change of morphometry to smaller more compact sperm heads are consistent with sperm being progressively cleared from the genital tract rather than continued shedding of immature or abnormal sperm by the seminiferous epithelium. A significant negative relationship was found between lag time and baseline sperm concentration, consistent with longer sperm-epididymal transit times associated with lower daily production rates.
Fuel cell power generating stations. [waste heat and effluents used in auxiliary power generator] (1978)

An integrated power generating plant includes a fuel cell for generating electrical energy directly and an auxiliary power generating plant that utilizes both the sensible heat and the heating value of effluents from the fuel cell by using working fluids in a closed cycle. The working fluid is vaporized by sensible heat and is superheated by combusting incompletely reacted fuels from the fuel cell.

Bioactive Polymers 68-Controlled Release of Neomycine-Furazolidone Bicomponent System from Xanthan Hydrogel (1993)

The neomycin-furazolidone-xanthan complex has been synthesized. Neomycin is covalently linked to xanthan, while furazolidone is inserted in the hydrogel formed by the reaction between neomycin and xanthan. The content of neomycin and furazolidone depends on the drug rate in the reaction medium. Thus, a zero-order kinetics is obtained for the release of both neomycin and furazolidone in basic medium. The complex's antimicrobial activity is intensified.
Evaluation of Therapies for Secondary Hyperparathyroidism Associated with Vitamin D Insufficiency in Chronic Kidney Disease (2023)

ERC was highly effective in both raising serum 25OHD and decreasing iPTH in patients with SHPT, VDI, and stage 3 or 4 CKD. iPTH-lowering response rates with ERC were similar to daily PLDC, the reference therapy; rates with IRC or HDC were significantly lower. ERC is an attractive alternative to vitamin D hormone therapy in CKD patients.
End-to-end UAV obstacle avoidance decision based on deep reinforcement learning (2022)

Aiming at the problem that the traditional UAV obstacle avoidance algorithm needs to build offline three-dimensional maps, discontinuous speed control and limited speed direction selection, we study the end-to-end obstacle avoidance decision method of UAV continuous action output based on DDPG(deep deterministic policy gradient) deep reinforcement learning algorithm. Firstly, an end-to-end decision control model based on DDPG algorithm is established. The model can output continuous control variables, namely UAV obstacle avoidance actions, according to the continuous state information perceived. Secondly, the training verification is carried out on the platform of UE4 + Airsim. The results show that the model can realize the end-to-end UAV obstacle avoidance decision. Finally, the 3DVFH(three dimensional vector field histogram) obstacle avoidance algorithm model with the same data source is compared and analyzed. The experiment shows that DDPG algorithm has better optimization effect on the obstacle avoidance trajectory of UAV.
Processing of volumetric data by slice- and process-based streaming (2007)

Although the main memory capacity of modern computers is constantly growing, the developers and users of data manipulation and visualization tools fight all over again with the problem of its shortage. In this paper, we advocate slice-based streaming as a possible solution for the memory shortage problem in the case of preprocessing and analysis of volumetric data defined over Cartesian, regular and other types of structured grids. In our version of streaming, data flows through independent processing units---filters---represented by individual system processes, which store each just a minimal fraction of the whole data set, with a slice as a basic data entity. Such filters can be easily interconnected in complex networks by means of standard interprocess communication using named pipes and are executed concurrently on a parallel system without a requirement of specific modification or explicit parallelization.
Motion-compensated iterative cone-beam CT image reconstruction with adapted blobs as basis functions (2008)

This paper presents a three-dimensional method to reconstruct moving objects from cone-beam X-ray projections using an iterative reconstruction algorithm and a given motion vector field. For the image representation, adapted blobs are used, which can be implemented efficiently as basis functions. Iterative reconstruction requires the calculation of line integrals (forward projections) through the image volume, which are compared with the actual measurements to update the image volume. In the existence of a divergent motion vector field, a change in the volumes of the blobs has to be taken into account in the forward and backprojections. An efficient method to calculate the line integral through the adapted blobs is proposed. It solves the problem, how to compensate for the divergence in the motion vector field on a grid of basis functions. The method is evaluated on two phantoms, which are subject to three different known motions. Moreover, a motion-compensated filtered back-projection reconstruction method is used, and the reconstructed images are compared. Using the correct motion vector field with the iterative motion-compensated reconstruction, sharp images are obtained, with a quality that is significantly better than gated reconstructions.
ABSENCE OF HYPERACUTE REJECTION IN PIG-TO-PRIMATE ORTHOTOPIC PULMONARY XENOGRAFTS (1995)

The shortage of organ donors for transplantation is more pronounced for the lung than for any other solid organ. To address this problem, we evaluated the feasibility of pulmonary xenotransplantation. Preliminary investigations demonstrated that orthotopically placed pig lungs in cynomologous monkey recipients could be engrafted up to 9 hr after reperfusion without evidence of hyperacute rejection. In this study, the rejection reaction of pig lungs transplanted orthotopically into baboons (n = 6) was further investigated by ELISA and immunohistochemistry. Four baboon recipients were killed at 24 hr and 2 recipients were killed at 72 hr after transplantation. Pulmonary arterial flow measurements demonstrated flow to the grafts, and systemic arterial and xenograft pulmonary venous blood gas analysis suggested function of the donor lungs during the course of engraftment. Serum levels of baboon anti-pig endothelial cell xenoantibody were normal and decreased minimally over time. Immunohistochemical staining of biopsies demonstrated trace IgG and IgM along graft endothelium 2 hr after reperfusion. At 8 hr, biopsy samples showed no immunoglobulin bound to endothelial cells. Staining for complement was negative. Fibrin and platelets were detected along xenograft endothelium. Despite these findings, the lung xenografts appeared injured and clinically rejected. During the first 8 hr after reperfusion, the grafts were hyperemic and subsequently became focally ecchymotic. Chest x-rays showed progressive pulmonary congestion. These findings suggest that the lung may be relatively resistant to antibody-mediated hyperacute rejection and efforts are being directed toward identifying the mechanism of the observed xenograft lung injury.

Determination of the Arterial Flow Fraction in Normal and Diseased Livers Using Constrained Deconvolution (1992)

There is some evidence that the ratio of the blood flow to the liver through the hepatic artery to the total flow to the liver through the hepatic artery and portal vein (the hepatic arterial flow fraction, AFF) is altered in the presence of cirrhosis. Several methods have been published that seek to provide an index of this ratio. These indices are dependent on factors other than the AFF and cannot provide a true measure of it. The impulse retention function of the liver has two components and these may be derived using a model-driven deconvolution of the arterial tracer concentration curve and the curve of tracer concentration in the liver. The AFF may then be obtained from the relative heights of these two components. Simulation studies show that the AFF calculated using this method is reasonably accurate and a small clinical series shows that it is capable of appropriate clinical classification of patients into cirrhotic and non-cirrhotic groups.
Characterization of the loss of seedling vigor in pea (Pisum sativum L.) (2004)

The physiological age of pea (Pisum sativum L.) seeds was accelerated using high temperature and relative humidity (RH), resulting in a range of vigor classes within one seed lot. This differentially aged seed was then used to determine the impact of seed vigor on plant growth and yield. For seeds incubated at 38°C for 2, 4, or 6 d at 100% RH prior to germination (accelerated aging), the percentage germination and rate of seedling emergence decreased with increasing time of aging. Aging at 38°C decreased seed vigor as indicated by reduced seedling root and shoot growth relative to higher-vigor seeds aged at 20°C. The respiration rate of seeds aged at 38°C was significantly higher than that of seeds aged at 20°C throughout the 6-d aging interval. However, no differences in respiration were evident during subsequent germination among the seeds aged at 38°C for 0, 2, 4, or 6 d. The higher-vigor seeds aged at 20°C had a higher respiration rate than those aged at 38°C during subsequent germination. Seeds that expressed high and low vigor in controlled-environment conditions showed similar trends in the field; however, seed vigor had no significant effect on total seed yield over two growing seasons. These data indicate that under certain conditions, the loss in seed vigor can be substantial without affecting overall yield, due to the plasticity of vegetative and reproductive growth in pea.

Human polymorphonuclear leukocyte response to Pseudomonas aeruginosa grown in biofilms (1990)

The interaction of human neutrophils with Pseudomonas aeruginosa biofilms was examined by using a chemiluminescence assay. The biofilms induced an oxidative burst response by polymorphonuclear leukocytes which was slow and only 25% of the response to planktonic bacteria. The reduced response to P. aeruginosa biofilms could play a role in the persistence of bacteria in chronic infections.
Application of the Volterra Series to the Analysis and Design of an Angle Track Loop (1972)

A typical function of an angle tracking loop is to keep a radar antenna pointed at a target. The error in pointing is directly related to successful operation of the tracking device; therefore, its behavior is of interest. For a tracker with a general polynomial nonlinearity, an arbitrary initial pointing error, and a bounded deterministic input, a method is developed for finding upper bounds on the magnitude of the tracking error using Volterra series techniques. Convergence regions of the Volterra series are also obtained. Applications of these results are made to a second-order tracking device.
Source descriptor selection schemes for multiple description coded services in 4G wireless communication systems (2005)

4G wireless communication networks are characterized by the need to support heterogenous terminals differing in size, display, battery, computational power, etc. For efficient usage of the wireless spectrum all devices should be served by the same spectrum instead of allocating spectra dedicated to the different terminal classes. This feature is naturally supported when the source coding of the traffic is done as a multiple description coding. The restoration quality of the information source is proportional to the quantity of the descriptors used in the restoration process. Hence, terminals with less capabilities may simply discard or not receive some of the descriptors, while high class terminals try to receive all information. In the case of partial reception of descriptors the performance can be improved by selection strategies for the descriptors. We advocate the usage of new descriptor selection schemes for multiple description coded services. The proposed schemes differ with respect to the availability of a feedback channel. All solutions are terminal oriented and are beneficial in the design of terminals that have robust and high quality services. Furthermore, our approaches inherently achieve fairness among different terminals. As an example of our results for video communication, we can show gains of 4 dB when the proposed approach is utilized in the system.
Evaluation of frescoes detachments by partial least square thermography (2014)

Several image processing algorithms are available to enhance the results of non destructive evaluation of artworks. This work is focused on the novel Partial Least Squares Thermography (PSLT) technique, that allows a strong data compression. A preliminary test on a fresco sample and a wide survey of the San Gottardo Church (located in Asolo, Italy) have been conducted to locate detachments with an active thermography technique. All the obtained thermal sequences have been post processed with different algorithms, including Principal Component Thermography (PCT), Thermographic Signal Reconstruction (TSR) and PLST. For the latter, two different approaches have been proposed and compared.
Physiological and pathological roles of purines: An update (1993)

Abstract In this review article, the early history of studies of purinergic neurotransmission and of purinoceptor subclassification is described. This is followed by a survey of current knowledge of the distribution of purinoceptors and of the physiological roles of purines in the nervous system, muscle, secretory, endocrine and immune cells, as well as in spermatocytes, osteoblasts, fibroblasts, and tumour cells. Recent studies of transduction mechanisms for different purinoceptor subtypes, as well as reports of the molecular properties of encoding genes for purinoceptors, are reviewed. The evolution of purinergic mechanisms and the long‐term ‘trophic’ actions of purines are discussed. Finally, the clinical potential of purines and related compounds for various cardiovascular and behavioural disorders. As well as for inflammation and cancer are considered. © 1993 Wiley‐Liss, Inc.
