Overview of development and regulatory aspects of high altitude platform system (2020)

High Altitude Platform (HAP) systems comprise airborne base stations deployed above 20 km and below 50 km to provide wireless access to devices in large areas. In this paper, two types of applications using HAP systems: one with HAP Station (HAPS) and the other with HAPS as International Mobile Telecommunication (IMT) Base Station (HIBS) are introduced. The HAP system with HAPS has already received wide recognition from the academia and the industry and is considered as an effective solution to provide internet access between fixed points in suburban and rural areas as well as emergencies. HAP systems with HIBS to serve IMT user terminal have just started to draw attention from researchers. The HIBS application is expected to be an anticipate mobile service application complementing the IMT requirement for cell phone or other mobile user terminals in which the service field of HAPS application cannot reach. After describing and characterizing the two types of systems, coexistence studies and simulation results using both the Power Fluxed Density (PFD) mask and separation distance based methods are presented in this paper. This paper also predicts future trends of the evolution paths for the HAP systems along with challenges and possible solutions from the standpoint of system architectures and spectrum regulation.
Thermal stability analysis of high brightness LED during high temperature and electrical aging (2007)

In this paper we report the analysis of thermal stability of High Brightness Light Emitting Diode subjected to thermal and bias ageing. The degradation mechanisms of several families of commercial available devices were investigated. In the first part of the work we estimated thermal resistance and thermal behaviour under dc bias condition. After this thermal characterisation two different ageing tests were carried out on devices: thermal aging at high temperature levels without biasing the devices and accelerated dc stress at nominal current value (400mA). At each step a complete electrical and optical characterisation of aged devices was performed, in order to find a correlation between different aging and a better understanding of degradation mechanism. This characterisation included I-V measurements, optical power vs current characteristics and spectral analysis. During thermal stress we observed the increase of forward voltage at nominal current and the degradation of optical power with nearly exponential kinetics. We found that lifetimes were well correlated with stress temperature: therefore it was possible to find an activation energy of degradation mechanism of about 1.5eV. Moreover, modifications of spectral properties during electrical and thermal stress were found. Thus, a package level analysis was carried out in order to clarify the role of modification in optical properties of reflector cup and the efficiency of phosphors. Finally, evaluation of differential structure functions indicated that stress induces also the worsening of the properties of the chip-to-package thermal path: this phenomenon has been attributed to the partial detachment and degradation of the ohmic contacts.
Upstream Demand Projection and Performance Mapping in Supply Chains (2006)

This paper deals with modeling steady-state behavior of a single-product, pull-type, serial supply chain, frequently encountered in the automotive industries. The proposed analytical method enables projection of the end-customer demand information to upstream of the supply chain and estimate demand forecast at the individual tier levels. The supply chain performance assessment is based on the due-time performance metric (DTP - probability to ship a required product/parts volume in a fixed time interval) under the assumption of customer demand following a discrete time Markov process, a special case for correlated demands. A numerical case study demonstrates the use of the DTP measure for a two-tier supply chain. The analytical results (verified by simulations) quantify important relationships in the supply chain, involving reliabilities of machines/stations, capacities of the buffers, demands correlation, and the due times and find use in performance assessment, optimization and design of supply chains.
Development of MRI‐based axillary numerical models and estimation of axillary lymph node dielectric properties for microwave imaging (2021)

The observed contrast between healthy and metastasized ALNs is a good indicator for the feasibility of a MWI system aiming to diagnose ALNs.

<title>Matched printing of colors with bilevel printers</title> (1992)

The system of CIE tristimulus coordinates is an accepted standard for the device independent exchange of color information. It is possible to print colors that are given in this system with low cost bilevel color printers of different print technologies. Results achievable with the Mannesmann Tally MT7400 C thermal transfer and the Mannesmann Tally MT92 C bubble jet printers are presented. The physical model of color reproduction with these printers is investigated. Based upon the model, an algorithm is chosen to determine areal fractions of the printer base colors that match a desired CIE color in a raster pixel. Print rasters are discussed, considering the special technical conditions of each print technology.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.

Molecular Epidemiology and Tuberculosis Control—Reply (2000)

In Reply: Dr Braden and colleagues and Dr Hannan reiterate 2 points of our article: that molecular and patient demographic data alone do not demonstrate an occurrence of an outbreak, and that molecular clustering is not synonymous with epidemiological linkage among cases.
Effects of Pentastarch on Global Cerebral Ischemia and Reperfusion (1995)

In Response: I appreciate Dr. Haring's interest in and comments regarding our study of the effects of hemodilution on cerebral edema after global cerebral ischemia. Although I share his desire to reach a definitive conclusion regarding the efficacy of colloid administration in various forms of brain injury, I am afraid that it is not possible to do so at this time. The multitude of animal models and the difficulty of conducting human clinical trials has complicated the task of demonstrating either the beneficial or deleterious effects of colloid administration. Although a key clinical trial of pentastarch in acute stroke was terminated because of excess mortality in the treatment group (nine pentastarch vs three control), much of this can be attributed to the fact that nearly twice as many patients with severe strokes were randomized to the pentastarch group (15 pentastarch vs eight control) [1]. Theoretically, hemodilution with colloids would be predicted to be of benefit from a variety of standpoints, including improved rheology, increased reflection coefficients, and antiinflammatory properties of some of the synthetic colloids. Unfortunately, based on a review of the current conflicting literature, one can only conclude that "the jury is still out" on this important topic. Mark H.

Cross-Normalization of MALDI Mass Spectrometry Imaging Data Improves Site-to-Site Reproducibility (2021)

Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI MSI) is an established tool for the investigation of formalin-fixed paraffin-embedded (FFPE) tissue samples and shows a high potential for applications in clinical research and histopathological tissue classification. However, the applicability of this method to serial clinical and pharmacological studies is often hampered by inevitable technical variation and limited reproducibility. We present a novel spectral cross-normalization algorithm that differs from the existing normalization methods in two aspects: (a) it is based on estimating the full statistical distribution of spectral intensities and (b) it involves applying a non-linear, mass-dependent intensity transformation to align this distribution with a reference distribution. This method is combined with a model-driven resampling step that is specifically designed for data from MALDI imaging of tryptic peptides. This method was performed on two sets of tissue samples: a single human teratoma sample and a collection of five tissue microarrays (TMAs) of breast and ovarian tumor tissue samples (N = 241 patients). The MALDI MSI data was acquired in two labs using multiple protocols, allowing us to investigate different inter-lab and cross-protocol scenarios, thus covering a wide range of technical variations. Our results suggest that the proposed cross-normalization significantly reduces such batch effects not only in inter-sample and inter-lab comparisons but also in cross-protocol scenarios. This demonstrates the feasibility of cross-normalization and joint data analysis even under conditions where preparation and acquisition protocols themselves are subject to variation.
Spectral CT Using Multiple Balanced K-Edge Filters (2014)

Our goal is to validate a spectral computed tomography (CT) system design that uses a conventional X-ray source with multiple balanced K-edge filters. By performing a simultaneously synthetic reconstruction in multiple energy bins, we obtained a good agreement between measurements and model expectations for a reasonably complex phantom. We performed simulation and data acquisition on a phantom containing multiple rods of different materials using a NeuroLogica CT scanner. Five balanced K-edge filters including Molybdenum, Cerium, Dysprosium, Erbium, and Tungsten were used separately proximal to the X-ray tube. For each sinogram bin, measured filtered vector can be defined as a product of a transmission matrix, which is determined by the filters and is independent of the imaging object, and energy-binned intensity vector. The energy-binned sinograms were then obtained by inverting the transmission matrix followed by a multiplication of the filter measurement vector. For each energy bin defined by two consecutive K-edges, a synthesized energy-binned attenuation image was obtained using filtered back-projection reconstruction. The reconstructed attenuation coefficients for each rod obtained from the experiment was in good agreement with the corresponding simulated results. Furthermore, the reconstructed attenuation coefficients for a given energy bin, agreed with National Institute of Standards and Technology reference values when beam hardening within the energy bin is small. The proposed cost-effective system design using multiple balanced K-edge filters can be used to perform spectral CT imaging at clinically relevant flux rates using conventional detectors and integrating electronics.
Glaskörper- und Fundusveränderungen beim Terson- Syndrom - Drei Falldarstellungen (1996)

In most eyes with Terson syndrome it is possible to wait for the spontaneous resorption of the blood. It is hypothesized that blood from a ruptured vein or capillary hydrodissects the internal limiting membrane from the underlying neurosensory retina. If a pars plana vitrectomy is performed the possibility of a hydraulical dissected internal limiting membrane has to be considered. Postoperatively perimacular retinal folds or fibrotic lines may occur, they didn't have any clinical evidence.
Efficacy and safety of two fixed-dose combinations of S-amlodipine and telmisartan (CKD-828) versus S-amlodipine monotherapy in patients with hypertension inadequately controlled using S-amlodipine monotherapy: an 8-week, multicenter, randomized, double-blind, Phase III clinical study (2016)

CKD-828 is an effective and safe option for patients with inadequate responses to S-amlodipine monotherapy.
Space-efficient Algorithms for Empty Space Recognition among a Point Set in 2D and 3D. (2011)

In this paper, we consider the problem of designing in-place algorithms for computing the maximum area empty rectangle of arbitrary orientation among a set of points in 2D, and the maximum volume empty axisparallel cuboid among a set of points in 3D. If n points are given in an array of size n, the worst case time complexity of our proposed algorithms for both the problems is O(n³); both the algorithms use O(1) extra space in addition to the array containing the input points.
Computers and iphones and mobile phones, oh my! (2009)

We present a logs-based comparison of search patterns across three platforms: computers, iPhones and conventional phones. Our goal is to understand how search users differ from computer-based search users, and we focus heavily on the distribution and variability of tasks that users perform from each platform. The results suggest that search usage is much more focused for the average user than for the average computer-based user. However, search behavior on high-end phones resembles computer-based search behavior more so than search behavior. A wide variety of implications follow from these findings. First, there is no single search interface which is suitable for all phones. We suggest that for the higher-end phones, a close integration with the standard computer-based interface (in terms of personalization and available feature set) would be beneficial for the user, since these phones seem to be treated as an extension of the users' computer. For all other phones, there is a huge opportunity for personalizing the search experience for the user's mobile needs, as these users are likely to repeatedly search for a single type of information need on their phone.

Fast atom bombardment combined with tandem mass spectrometry for analysis of a complex mixture of lipo-oligopeptides fromNocardia rubra cell wallskeleton (1989)

Experimental variables in fast atom bombardment combined with tandem mass spectrometry based on low-energy collision-induced dissociation have been systematically invetigated in order to optimize parameters for analysis of synthetic lipo-oligopeptides. The parameters studied were matrix, ion polarity, collision gas, collision gas pressure and collision energy. The optimal parameters recommended in this study have been applied to the N-terminal amino acid seuquence determination of lipopeptide obtained from Nocardia rubra cell wall skeleton. Daughter and parent ion experiments with negative ion fast atom bombardment combined with tandem mass spectrometry have proven to be very useful for structure elucidation of a complex mixture of lipo-oligopeptides.

Endocannabinoid Signaling Mediates Psychomotor Activation by Adenosine A 2A Antagonists (2010)

Adenosine A(2A) receptor antagonists are psychomotor stimulants that also hold therapeutic promise for movement disorders. However, the molecular mechanisms underlying their stimulant properties are not well understood. Here, we show that the robust increase in locomotor activity induced by an A(2A) antagonist in vivo is greatly attenuated by antagonizing cannabinoid CB(1) receptor signaling or by administration to CB(1)(-/-) mice. To determine the locus of increased endocannabinoid signaling, we measured the amount of anandamide [AEA (N-arachidonoylethanolamine)] and 2-arachidonoylglycerol (2-AG) in brain tissue from striatum and cortex. We find that 2-AG is selectively increased in striatum after acute blockade of A(2A) receptors, which are highly expressed by striatal indirect-pathway medium spiny neurons (MSNs). Using targeted whole-cell recordings from direct- and indirect-pathway MSNs, we demonstrate that A(2A) receptor antagonists potentiate 2-AG release and induction of long-term depression at indirect-pathway MSNs, but not direct-pathway MSNs. Together, these data outline a molecular mechanism by which A(2A) antagonists reduce excitatory synaptic drive on the indirect pathway through CB(1) receptor signaling, thus leading to increased psychomotor activation.
Design and implementation of the real-time color image correction system (2010)

When the color linear array CCD camera works, the output color image has the dislocation phenomenon which has seriously affected the human visual effect. At the same time the dislocation phenomenon has also brought great trouble to the image processing. In order to resolve this problem, a real-time collection system with the PCI interface has been developed. The system not only has the image collection function but also has the communication function. The system is so convenient that it can be easy to achieve control and data transfer. In the system, hardware circuit module is designed with the block-style thinking. The FPGA is the core of the whole hardware circuit module, responsible for data transmission, timing logic control and serial communication. Double buffer structure ensures the data transmission reliably. The PCI driver development and the PC software application are described seriously in the software module. The DMA mode and the event notification method are adopted in the driver. The RGB color correction algorithm is introduced seriously in the software application. The experiment results show that the system has met the requirement targets. It can achieve the maximum transfer rate of 40MBps when running in the DMA mode. The system is stable and real-time when it works outdoors.
Toward content-centric privacy in ICN (2013)

We design a content-centric privacy scheme for Information-Centric Networking (ICN). We enhance ICN's ability to support data confidentiality by introducing attribute-based encryption into ICN and making it specific to the data attributes. Our approach is unusual in that it preserves ICN's goal to decouple publishers and subscribers for greater data accessibility, scalable multiparty communication and efficient data distribution. Inspired by application-layer publish-subscribe, we enable fine-grained access control with more expressive policies. Moreover, we propose an attribute-based routing scheme that offers interest confidentiality. A prototype system is implemented based on CCNx, a popular open source version of ICN, to showcase privacy preservation in Smart Neighborhood and Smart City applications.
3DMatch: Learning Local Geometric Descriptors from RGB-D Reconstructions (2017)

Matching local geometric features on real-world depth images is a challenging task due to the noisy, low-resolution, and incomplete nature of 3D scan data. These difficulties limit the performance of current state-of-art methods, which are typically based on histograms over geometric properties. In this paper, we present 3DMatch, a data-driven model that learns a local volumetric patch descriptor for establishing correspondences between partial 3D data. To amass training data for our model, we propose a self-supervised feature learning method that leverages the millions of correspondence labels found in existing RGB-D reconstructions. Experiments show that our descriptor is not only able to match local geometry in new scenes for reconstruction, but also generalize to different tasks and spatial scales (e.g. instance-level object model alignment for the Amazon Picking Challenge, and mesh surface correspondence). Results show that 3DMatch consistently outperforms other state-of-the-art approaches by a significant margin. Code, data, benchmarks, and pre-trained models are available online at http://3dmatch.cs.princeton.edu.
Reflection of bounce phenomenon in TEOAE in humans: dependence upon exposure parameters. (2007)

The bounce phenomenon is an alteration of hearing acuity after presentation of loud tones. Generally, it implies the improvement in hearing acuity that followed by the worsening. The dependence of the bounce upon exposure stimulus parameters has been evaluated in the present study. Normally hearing subjects were investigated, while transiently evoked otoacoustic emission, TEOAE, has been recorded to estimate the event objectively. In the 1st experiment, the bounce indices have been compared under different intensities, 55-100 dB SPL, of exposure-tone of 250-Hz frequency. At lower intensities, 65-75 dB SPL, the augmentation phase in TEOAE bounce reflections exceeded the depression one. At higher intensities, 80-95 dB SPL, both phases of the bounce were of similar magnitudes. The event appeared thus bipolar and symmetric. At the highest intensity, 100 dB SPL, TEOAE drop has hardly been preceded by any augmentation. In the 2nd experiment, the bounce manifestations have been compared under different exposure-tone frequencies, 250, 500, and 2000 Hz. Under 250- and 500-Hz frequencies, the bounce was of similar magnitudes. Under 2000-Hz frequency, a conventional bounce has not been seen, a trend to the overall TEOAE decrement being observed only. The bounce mechanism is discussed and its complex rather than simple nature is considered.
Cervical Interbody Fusion Cages (1998)

The use of a threaded intervertebral fusion cage, with or without hydroxyapatite coating, filled with autogenous bone graft provides a fusion rate that is slightly better than those previously reported using autogenous interbody bone grafts with or without plate stabilization. Recombinant human bone morphogenetic protein-2-filled cages resulted in a much higher arthrodesis rate and accelerated bone formation compared with either autogenous bone-filled BAK devices, or autogenous interbody bone grafts with or without plate stabilization.

Elastoresistance of n-type silicon on sapphire (1974)

Elastoresistance of n -type silicon on sapphire is measured. The measurement is performed with a gated MOS Hall bridge. An extrapolation method is developed to minimize errors due to aluminum autodoping. From the obtained result, it is concluded that the lateral stress present in the silicon causes almost complete depopulation of the energy surface in the kz direction, perpendicular to the surface of the silicon. This in turn causes pronounced changes in the transport properties, such as resistivity or Hall mobility. Qualitative agreement with the theory, in which no scattering mechanism is considered, is obtained.
