Load Balancing for Communication Networks via Data-Efficient Deep Reinforcement Learning (2021)

Within a cellular network, load balancing between different cells is of critical importance to network performance and quality of service. Most existing load balancing algorithms are manually designed and tuned rule-based methods where near-optimality is almost impossible to achieve. These rule-based meth-ods are difficult to adapt quickly to traffic changes in real-world environments. Given the success of Reinforcement Learning (RL) algorithms in many application domains, there have been a number of efforts to tackle load balancing for communication systems using RL-based methods. To our knowledge, none of these efforts have addressed the need for data efficiency within the RL framework, which is one of the main obstacles in applying RL to wireless network load balancing. In this paper, we formulate the communication load balancing problem as a Markov Decision Process and propose a data-efficient transfer deep reinforcement learning algorithm to address it. Experimental results show that the proposed method can significantly improve the system performance over other baselines and is more robust to environmental changes.

A Vascular Modulator, Hepatocyte Growth Factor, Is Associated With Systolic Pressure (1996)

Endothelial cells are known to secrete various antiproliferative and vasodilating factors, such as nitric oxide and natriuretic peptides. The presence of endothelial dysfunction, well known in hypertensive individuals, potentially results in the development and progression of atherosclerosis. Therefore, it is important to know the factors that might influence endothelial cell growth. We examined the mitogenic actions of hepatocyte growth factor (HGF) on human endothelial and vascular smooth muscle cells. Exogenously added human recombinant HGF stimulated endothelial but not vascular smooth muscle cell growth in a dose-dependent manner. We also compared the mitogenic action of HGF with that of basic fibroblast growth factor and vascular endothelial growth factor. Interestingly, the mitogenic action of HGF on endothelial cells was greater than the actions of basic fibroblast growth factor and vascular endothelial growth factor, whereas basic fibroblast growth factor but not HGF and vascular endothelial growth factor stimulated vascular smooth muscle cell growth. Given the characteristics of HGF as an endothelium-specific growth factor, we evaluated the relationship of circulating HGF and blood pressure in normotensive and hypertensive subjects. Serum HGF concentration has been reported to be elevated in response to organ damage, such as in hepatitis and nephritis, and recent findings show that HGF may play an important role in tissue regeneration. We hypothesized that HGF might contribute to the protection or repair of vascular endothelial cells. If so, serum HGF level might be elevated in response to endothelial cell damage induced by hypertension. To test this hypothesis, we measured serum levels of HGF, lipoprotein(a), plasminogen activator inhibitor-1, tissue plasminogen activator, total cholesterol, and blood pressure in 41 normotensive and hypertensive subjects without liver, kidney, or lung damage. Serum HGF concentration was significantly correlated with systolic pressure (P < .01, r = .43) but not diastolic pressure. Serum HGF concentration in hypertensive subjects was significantly higher than in normotensive subjects. None of the other factors showed any correlation with blood pressure. We have demonstrated that HGF is an endothelium-specific growth factor whose serum concentration is significantly associated with systolic pressure. These results suggest that HGF secretion might be elevated in response to high blood pressure as a counterregulatory system against endothelial dysfunction.
The effects of using a hypertext tool for selecting design guidelines (1992)

Designing a User-system Interface (USI) is a complex task that has been approached in many ways. One approach has been to use USI design guidelines to help improve the quality and consistency of USIs. To be effective, a general set of guidelines must be tailored to a specific application. One popular set of guidelines is the Smith and Mosier Guidelines for Designing User Interface Software (1986). This study investigated the effects of using a computer-based hypertext design aid (DRUID, Dynamic Rules for User Interface Design) for the selection of USI guidelines by both experienced and novice Guidelines users. Results Indicate that, in general, DRUID performed as well as the book. Subjects used both the book and hypertext presentation media effectively. However subjects selected more guidelines that were relevant with the book because subjects read less when using DRUID. Subjectively, the software was preferred because it provided assistance in the selection process and provided additional time-saving design aids not available in the book. Results showed that the presentation of the guidelines could be improved for both media, and many of the factors that led subjects to select fewer relevant guidelines with DRUID could be overcome with improved USI design and implementation of DRUID. This suggests that, to overcome the limitations of presenting large texts on-line, value added'' (e.g., automated checklists) features should be incorporated into on-line tools to help users better perform their tasks.
Scanning and Surface Alignment Considerations in Chemical Imaging with Desorption Electrospray Mass Spectrometry (2008)

The effects of surface scanning mode (raster vs unidirectional scanning) and the constancy of spray tip-to-surface and atmospheric sampling interface capillary-to-surface distances on chemical image quality using desorption electrospray ionization mass spectrometry were investigated. Unidirectional scanning was found to provide a spatially and a quantitatively more precise chemical image of the surface as compared to raster scanning. Maintaining constant spray tip-to-surface and atmospheric sampling interface capillary-to-surface distances during an imaging experiment was found to also be critical. An automation process was implemented using a custom image analysis software (HandsFree Surface Analysis) to keep these distances constant during the surface sampling experiment. Improved chemical image quality afforded through this software control was illustrated by imaging printed objects on normal copy paper.

Stochastic Analysis and Modeling of a Tree-Based Group Key Distribution Method in Tactical Wireless Networks (2014)

A number of key management challenges are encountered when operating tactical communication systems using a group-wide shared key. A large portion of such communications occurs over low bit-rate channels, and all communication channels must be available at any moment for mission action. Current over-the-air rekeying protocols consume too much channel bit-rate to be practical for large tactical radio networks. This caused an off-line pre-placed key (PPK) approach to become most commonly used key distribution method in these environments. Unfortunately, with this key management scheme, revoking group membership requires a full intra-mission rekey, which can be dangerous in a battlefield situation. This paper introduces a new group key distribution method called Viral Electronic Key Exchange (VEKE). This paper examines the protocol as an extension to the Internet Key Exchange (IKE) protocol, but any electronic key exchange protocol can be used (Ex. IKE v2). A feature of this protocol is a parallel key distribution scheme enabled by propagating the key management role to authenticated nodes while establishing security associations across the network. We performed a comprehensive stochastic analysis to develop a model for computing the expected rekey time across the entire group, taking into account the likelihood of node jamming, channel failures, and message corruption. This model was verified with a Monte-Carlo simulation. Our results confirmed that the VEKE protocol can accomplish an over-the-air rekey in a short period of time, even over low bit-rate systems, while preserving rigid security and channel availability properties of the network. It also allows for the amount of pre-placed public-key material and other preparations necessary in tactical networks to be minimized.
A short synthetic peptide (DTRPAP) induces anti-mucin (MUC-1) antibody, which is reactive with human ovarian and breast cancer cells. (1998)

The present study describes the production of a synthetic hexapeptide (DTRPAP)-based anti-mucin (MUC-1) antibody, similar to those produced using either the intact mucin antigen or tumor extracts. This antibody was generated by immunization of rabbits with the synthetic peptide conjugated to bovine serum albumin as a carrier. Using both the ELISA and FACS analysis methods, we have shown that the antibody is reactive with human ovarian and breast cancer cells, but not with normal epithelial breast cells. This antibody is different from the previously reported anti-mucin HMFG-1, HMFG-2 and SM-3 monoclonal antibodies, since competitive experiments with the free synthetic peptide revealed only a 30% inhibition of HMFG-1 binding to the ovarian (OVCAR-3) cancer cells, as compared to 78% inhibition of the anti-synthetic peptide antibody. The peptide was non-inhibitory for HMFG-2, and induced a significant and reproducible stimulation of the SM-3 binding activity to the tumor cells.

Risk-Based Allowed Outage Time and Surveillance Test Interval Extensions for Angra 1 (2012)

In this work, Probabilistic Safety Assessment (PSA) is used to evaluate Allowed Outage Times (AOT) and Surveillance Test Intervals (STI) extensions for three Angra 1 nuclear power plant safety systems. The interest in such an analysis lies on the fact that PSA comprises a risk-based tool for safety evaluation and has been increasingly applied to support both the regulatory and the operational decision-making processes. Regarding Angra 1, among other applications, PSA is meant to be an additional method that can be used by the utility to justify Technical Specification relaxation to the Brazilian regulatory body. The risk measure used in this work is the Core Damage Frequency, obtained from the Angra 1 Level 1 PSA study. AOT and STI extensions are evaluated for the Safety Injection, Service Water and Auxiliary Feedwater Systems using the SAPHIRE code. In order to compensate for the risk increase caused by the extensions, compensatory measures as (1) test of redundant train prior to entering maintenance and (2) staggered test strategy are proposed. Results have shown that the proposed AOT extensions are acceptable for two of the systems with the implementation of compensatory measures whereas STI extensions are acceptable for all three systems.
Aerodynamics of a Badminton Shuttlecock (2009)

This paper presents a class project that can be performed in a junior-level fluid mechanics course. Students gain experience in design and conducting experiments, and in reviewing the relevant technical literature. Experiments were conducted to determine the drag coefficient of a badminton shuttlecock. Two types of testing were conducted: wind tunnel tests of a full-scale model, and drop tests using a high-accuracy radar gun. The drag coefficients calculated from these measurements were then compared to the limited data available in the literature. The range of drag coefficients measured was from 0.55 to 0.65.
High efficiency, oxidation resistant radio frequency susceptor (2023)

An article and method of producing an article for converting energy from one form to another having a pitch-derived graphitic foam carbon foam substrate and a single layer coating applied to all exposed surfaces wherein the coating is either silicon carbide or carbides formed from a Group IVA metal. The article is used as fully coated carbon foam susceptors that more effectively absorb radio frequency (RF) band energy and more effectively convert the RF energy into thermal band energy or sensible heat. The essentially non-permeable coatings also serve as corrosion or oxidation resistant barriers.
Implications of Planck2015 for inflationary, ekpyrotic and anamorphic bouncing cosmologies (2016)

The results from Planck2015, when combined with earlier observations from WMAP, ACT, SPT and other experiments, were the first observations to disfavor the "classic" inflationary paradigm. To satisfy the observational constraints, inflationary theorists have been forced to consider plateau-like inflaton potentials that introduce more parameters and more fine-tuning, problematic initial conditions, multiverse-unpredictability issues, and a new 'unlikeliness problem.' Some propose turning instead to a "postmodern" inflationary paradigm in which the cosmological properties in our observable universe are only locally valid and set randomly, with completely different properties (and perhaps even different physical laws) existing in most regions outside our horizon. By contrast, the new results are consistent with the simplest versions of ekpyrotic cyclic models in which the universe is smoothed and flattened during a period of slow contraction followed by a bounce, and another promising bouncing theory, anamorphic cosmology, has been proposed that can produce distinctive predictions.
Consistency and performance of concurrent interactive database applications (2002)

In many modern database applications, there is an emerging need for interactive environments where users directly manipulate the contents of the database. Graphical user interfaces (GUIs) display images of the database which must reflect a consistent up-to-date state of the data with minimum perceivable delay to the user. Moreover, the possibility of several applications concurrently displaying different views of the same database increases the overall system complexity. In this paper, we show how design, performance and concurrency issues can be addressed by adapting existing database techniques. We propose the use of suitable display schemas whose instances compose active views of the database, an extended client caching scheme which is expected to yield significant performance benefits, and a locking mechanism that maintains consistency between the GUIs and the database.

Mimicking sponges: Well-defined crystalline nanoparticles of cubic BaTiO3 are prepared at a very low temperature by using a bio-inspired methodology. A bimetallic alkoxide is used as a single-source precursor in a vapor-diffusion sol–gel synthesis. Water and catalyst (HCl) are delivered in a spatial and temporal gradient to promote the slow growth of nanoparticles.
Enhancing Single-Document Summarization by Combining RankNet and Third-Party Sources (2007)

We present a new approach to automatic summarization based on neural nets, called NetSum. We extract a set of features from each sentence that helps identify its importance in the document. We apply novel features based on news search query logs and Wikipedia entities. Using the RankNet learning algorithm, we train a pair-based sentence ranker to score every sentence in the document and identify the most important sentences. We apply our system to documents gathered from CNN.com, where each document includes highlights and an article. Our system significantly outperforms the standard baseline in the ROUGE-1 measure on over 70 % of our document set. 1
Immunohistochemically detected expression of motility-related protein-1 (MRP-1/CD9) in lung adenocarcinoma and its relation to prognosis (1997)

Motility-related protein-1 (MRP-1)/CD9 is a trans-membrane glycoprotein closely associated with suppression of cell motility and reduced metastatic potential of some tumor cells. We currently report that, according to the RT-PCR method for MRP-1/CD9 gene expression, patients with low expression of MRP-1/CD9 in non-small-cell lung cancer, especially the adenocarcinoma type, showed short overall survival. Then, to determine accurately the prognostic value of MRP-1/CD9 product levels in lung-adenocarcinoma cells, we immunohistochemically investigated its expression in 132 lung-adenocarcinoma patients undergoing potentially curative surgery. Of these patients, 44 (33%) showed reduced expression of MRP-1/CD9 in cancer cells, and an inverse association was observed between its expression and factors associated with tumor progression, such as nodal involvement (p = 0.029) or stage (p = 0.028). Patients with reduced expression of MRP-1/CD9 showed a significantly worse prognosis in overall survival (p = 0.005) and disease-free survival (DFS; p < 0.0001) than those with stronger expression; and even among patients with stage-I disease, similar results were obtained (overall survival, p = 0.038; DFS, p = 0.012). In a multivariate analysis, immunohistochemical MRP-1/CD9-expression level was an independent prognostic factor for DFS (p = 0.021), but not for overall survival (p = 0.572). Thus, immunohistochemical MRP-1/CD9-expression level solely in lung-adenocarcinoma cells within the tumor tissue appears to be a prognostic factor for DFS, and may be useful for detecting a high-risk sub-group of recurrence during the post-operative clinical course of the disease.
Interactive Visual Analysis of Hierarchical Enterprise Data (2010)

In this paper, we present an interactive visual technique for analysing and understanding hierarchical data, which we have applied to analysing a corpus of technical reports produced by a corporate research laboratory. The analysis begins by selecting a known entity, such as a topic, a report, or a person, and then incrementally adds other entities to the graph based on known relations. As this bottom-up knowledge building process proceeds, meaningful graph structure may appear and reveal previously unknown relations. The ontology of the data, which represents the types of entities in the data and all possible relations among them, is displayed as a guide to the analyst in the process. The analyst may interact with the ontology graph or the data graph directly. In addition, we provide a set of filtering, searching, and abstraction methods for the analyst to manage the complexity of the graph. In contrast to a top-down approach, which usually starts with an overview of the whole data set for exploration, a bottom-up approach is generally more efficient, because it often only touches a very small fraction of the data. We present several case studies to demonstrate the efficacy of this interactive graph-based analysis technique for both intra- and inter-hierarchy analysis.
Generalized efficiency measure for an Above-IC multifilar transformer applied to multiport integrated passive devices (2010)

This paper formulates generalized transformer efficiency associated with the applications of Above-IC multifilar transformers to multiport integrated passive devices (IPDs). The formulation derives the power loss ratio for a multifilar transformer in multiport configuration based on a terminated microwave network and then leads to the expression of passive efficiency using the concept of power conservation. For demonstration, the S-parameters for several different types of three-port transformers have been measured to compute their passive efficiency and further predict the minimum available insertion loss of the three-port IPDs such as baluns and combiners that use these three-port transformers.
Supported Electrolyte Thin Film Synthesis of Solid Oxide Fuel Cells (2003)

▪ Abstract Solid oxide fuel cells operating at temperatures below 800°C require the use of supported thin film solid electrolytes. A variety of processing methods are reviewed that can deliver electrolyte films with satisfactory performance. These include vapor phase, sol-gel, and powder methods such as colloidal deposition. An important consideration is that a number of these processing methods may not meet the low cost required by commercialization. The most cost-effective methods are considered to be simple powder methods combined with co-firing.
Simulation of Magnetic Nanoparticles in Blood Flow for Magnetic Drug Targeting Applications (2013)

A new magnetic drug targeting model of placing an array of permanent magnets and coils inside hollow organs of the body was developed. This gives the possibility to target e. g. prostate carcinoma, oesophagus adenocarcinoma or bile duct Klatskin tumours with drugs bounded to magnetic nanoparticles. The targeting model uses FEM based simulations and describes the interaction of an external magnetic field with single suspended superparamagnetic iron oxide (SPIO) nanoparticles in blood flow, thereby, quantifying the amount of the accumulated SPIO at a vessel wall.
