Assessing the Accuracy of Real Time Kinematic GPS Positions for the Purposes of Cadastral Surveying (1996)

Abstract The development of real time kinematic Global Positioning System (GPS) technology has provided the surveying community with a potentially powerful tool for performing cadastral surveys. The Victorian Surveyors (Cadastral Surveys) Regulations 1995 prescribe a length accuracy of ± (10mm+60ppm) for all measured and determined lengths. The aim of this paper is to assess the ability of real time kinematic GPS techniques to meet this legislative requirement. A statistical analysis of the results of seven real time GPS kinematic surveys and a high precision traverse is presented. The variance of a determined length using GPS is derived and found to be a function of the length of the two GPS baselines used to determine each end of the line. Based on this theory, it is shown that the length based tolerance is restrictive for the use of GPS. A positional tolerance is demonstrated to be more relevant and a tolerance of 25mm claimed to be realistic for real time GPS techniques and equipment.
Sub-25 nm High-Harmonic Generation with a 78-MHz Repetition Rate Enhancement Cavity (2012)

We demonstrate efficient output coupling of high harmonics generated in a high-power femtosecond 78-MHz enhancement cavity through an on-axis opening in a mirror. Radiation down to 23 nm (harmonic order 45) is observed.
Analysis of the degradation of a spaceflight tape recorder (1992)

Beginning shortly after launch, and continuing from orbital insertion around Venus through the prime science mission, one of the two magnetic tape recorders aboard the Magellan spacecraft experienced an increasing bit-error rate. As depicted in Figure 1, the bit errors from the recorder eventually caused the percentage of Venusian radar data frames experiencing errors to exceed 5%, and caused the recorder to be deemed unusable. The bit errors were manifested not as single-bit errors nor as burst errors, which are common errors that may be expected from tape recorders. Instead, as shown in Table 1, the errors were usually characterized by occurrences of slipped bits associated with flipped bits. For example, "1001" radar data patterns were recovered from the recorder as "111" patterns.
The Cooperation Functions between IACS and Infection Control Management (2022)

In the manufacturing industry, infection control of employees is one of the business risks, and management measures are taken. The Ministry of Health, Labor and Welfare of Japan has also announced measures to prevent infection in the workplace and is calling on companies to comply. Since the measures are published as a checklist, the implementation can be confirmed in the daily safety and health activities of the company. However, human checks take some efforts and human mistakes. On the other hand, the current Industrial Automation Control System (IACS) monitors the field environment and employee status, so many items on the checklist can be measured and recorded. This paper considers cooperation functions of IACS to infection control checklist, and discusses the possibility that infection control will be a new functional category of IACS.

Nuclear scoping analysis of ITER bioshield top lid toward its preliminary design review (2023)

During ITER operations, electronics located in the crane hall, which is above the tokamak, will be exposed to neutron and photon fields from both the plasma and the activated water. To protect the electronics, the implementation of dedicated shielding on the crane hall platform and the bioshield top lid is required. The design demands optimisation attending to constructability, weight limits, and radiation shielding requirements. This work evaluates eight shielding configurations by assessment of the neutron flux and dose accumulated over 4700 h of operation at 500 MW for electronics protection. This corresponds to a neutron wall load of 0.3 MW a/m² as specified in the ITER Project Specification. An intermediate-source approach has been followed with SRC-UNED, considering all relevant radiation sources while minimising the computational time required. Results were presented at the top lid Conceptual Design Review aiming to support decision-making. Further optimisation has since been performed to reach a top lid proposal for its Preliminary Design Review. All outcomes show that radiation levels above the north and south crane hall platforms are compatible with the critical electronics requirements.

Privacy in VoIP Networks: A k-Anonymity Approach (2009)

Peer-to-peer VoIP (voice over IP) networks, exemplified by Skype, are becoming increasingly popular due to their significant cost advantage and richer call forwarding features than traditional public switched telephone networks. One of the most important features of a VoIP network is privacy (for VoIP clients). Unfortunately, most peer-to-peer VoIP networks neither provide personalization nor guarantee a quantifiable privacy level. In this paper we propose novel flow analysis attacks that demonstrate the vulnerabilities of peer-to-peer VoIP networks to privacy attacks. We present detailed experimental evaluation that demonstrates these attacks quantifying performance and scalability degradation.
Measuring the lifetime of silicon nanocrystal solar cell photo-carriers by using Kelvin probe force microscopy and x-ray photoelectron spectroscopy (2014)

We report the first measurements of photo-carrier lifetimes in silicon nanocrystal-based third generation solar cells by Kelvin force microscopy and x-ray photoelectron spectroscopy under modulated frequency light illumination. A high concentration of active defects at the interface between the nanocrystals and silicon oxide matrix may be passivated by annealing under hydrogen. We found that the carrier lifetime, τ, is τ = 7 × 10(-5) s and τ = 3.5 × 10(-5) s within 10% accuracy for the hydrogen passivated and non-passivated nanocrystals, respectively. We used an exponential model to confirm the experimental potential measurements and to estimate photo-carrier lifetimes.
A Heterogeneous Built-In Self-Repair Approach Using System-Level Synthesis Flexibility (2004)

Summary and Conclusions -A novel methodology is proposed for designing fault-tolerant real-time multi-processor systems-on-a-chip to achieve optimal productivity. The methodology employs the heterogeneous built-in-self-repair (BISR) based on graceful degradation and yield enhancement techniques as an embedded optimization engine. The technique exploits the flexibility provided in task-level scheduling and algorithm selection steps. A hardware fault model is developed for modern super-scalar processors and multi-processors which enables an efficient treatment of the synthesis and compilation goals. For the first time, heterogeneous BISR is used at the task level. The key idea is to adapt scheduling and algorithm selection to the available nonfaulty resources. If there is a fault in memory, the algorithms that use less memory are selected and the scheduler exploits the other abundant resource, viz, the processors, more vigorously to compensate for the loss of part of memory. Similarly, a fault in a processor is backed up by memory. The synthesis approach minimizes the degradation in performance for single or multiple faults using simulated annealing-based algorithm selection, scheduling, and assignment algorithms. On the large set of examples this adaptive algorithm selection and scheduling technique has achieved important improvement of throughput compared to conventional nonadaptive schemes. The experimental results also indicate that important improvement in productivity can be achieved by using the extra throughput gained from the technique.
Origin and Characterization of Multipotential Mesenchymal Stem Cells Derived from Adult Human Trabecular Bone (2005)

Much of the knowledge regarding the regulatory pathways for adult stem cell self-renewal and differentiation has been obtained from the results of in vitro cultures. However, it is unclear if adult stem cells are controlled in the same way under physiological conditions. We examined this issue with respect to the migration of stem cells to tissue injury and how switch from a migratory state to one of proliferation wherein they participate in development. Building on our previous identification of multipotent stem cells in trabecular bone, we have examined the in vitro behavior of these cells within the bone milieu. We found that cell proliferation is inhibited within the trabecular bone niche as cells migrate out of the trabecular bone prior to proliferation. Additionally, multiple cell types were detected in adult trabecular bone, including osteoblasts, osteoclasts, endothelial cells, and Stro-1-positive mesenchymal stem cells. Furthermore, we demonstrated that Stro-1-positive cells migrated out of their native bone niche to generate multipotential stem and progenitor cells during in vitro culture. We conclude that self-renewal and differentiation of adult stem cells in connective tissues are tightly controlled and separately orchestrated processes. A regulatory network of extrinsic factors and intrinsic signals acts to stimulate the exit of stem cells from their niche so that they can localize to sites of wound healing, where they participate in development after functional differentiation.
N-Glycosylation of the Human Granulocyte-Macrophage Colony-stimulating Factor Receptor α Subunit Is Essential for Ligand Binding and Signal Transduction (1995)

The alpha subunit of the receptor for human granulocyte-macrophage colony-stimulating factor (GM-CSF) is a glycoprotein containing 11 potential N-glycosylation sites in the extracellular domain. We examined the role of N-glycosylation on alpha subunit membrane localization and function. Tunicamycin, an N-glycosylation inhibitor, markedly inhibited GM-CSF binding, GM-CSF-induced deoxyglucose uptake, and protein tyrosine phosphorylation in HL-60(eos) cells but did not affect cell surface expression of the alpha subunit as detected by an anti-alpha subunit monoclonal antibody. In COS cells expressing the alpha subunit and treated with tunicamycin, N-unglycosylated alpha subunit was expressed and transported to the cell surface but was not capable of binding GM-CSF. High affinity binding in COS cells expressing both alpha and beta subunits was also blocked by tunicamycin treatment. These studies indicate that N-linked oligosaccharides are essential for alpha subunit ligand binding and signaling by the human GM-CSF receptor.
A Unified Game-Theoretic Approach to Multiagent Reinforcement Learning (2017)

To achieve general intelligence, agents must learn how to interact with others in a shared environment: this is the challenge of multiagent reinforcement learning (MARL). The simplest form is independent reinforcement learning (InRL), where each agent treats its experience as part of its (non-stationary) environment. In this paper, we first observe that policies learned using InRL can overfit to the other agents' policies during training, failing to sufficiently generalize during execution. We introduce a new metric, joint-policy correlation, to quantify this effect. We describe an algorithm for general MARL, based on approximate best responses to mixtures of policies generated using deep reinforcement learning, and empirical game-theoretic analysis to compute meta-strategies for policy selection. The algorithm generalizes previous ones such as InRL, iterated best response, double oracle, and fictitious play. Then, we present a scalable implementation which reduces the memory requirement using decoupled meta-solvers. Finally, we demonstrate the generality of the resulting policies in two partially observable settings: gridworld coordination games and poker.
Toward Whole-Brain Minimally-Invasive Vascular Imaging (2022)

Imaging the brain vasculature can be critical for cerebral perfusion monitoring in the context of neurocritical care. Although ultrasensitive Doppler (UD) can provide good sensitivity to cerebral blood volume (CBV) in a large field of view, it remains difficult to perform through the skull. In this work, we investigate how a minimally invasive burr hole, performed for intracranial pressure (ICP) monitoring, could be used to map the entire brain vascular tree. We explored the use of a small motorized phased array probe with a non-implantable preclinical prototype in pigs. The scan duration (18 min) and coverage (62 ± 12 % of the brain) obtained allowed global CBV variations detection (relative in brain Doppler <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">decrease</inf> = −3[−4-+16]% & Doppler <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">increase</inf> . = +1[−3-+15]%, n = 6 & 5) and stroke detection (relative in core Dopplerstroke. = −25%, n = 1). This technology could one day be miniaturized to be implanted for brain perfusion monitoring in neurocritical care.

Al-2.72 Microfabrication (2021)

As increasingly smaller molecular materials and material structures are devised or developed for technological applications, the demands on the processes of lithography now routinely include feature sizes that are of the order of 10 nm. In reaching such a fine level of resolution, the methods of lithography have increased markedly in sophistication and brought into play 2terminology that is unfamiliar, on the one hand, to scientists tasked with the development of new lithographic materials or, on the other, to the engineers who design and operate the complex equipment that is required in modern-day processing. Publications produced by scientists need to be understood by engineers and vice versa, and these commonly arise from collaborative research that draws heavily on the terminology of two or more of the traditional disciplines. It is developments in polymer science and material science that lead progress in areas that cross traditional boundaries, such as microlithography. This document provides the exact definitions of a selection of unfamiliar terms that researchers and practitioners from different disciplines might encounter.

Event Access Expressions: A Business User Language for Analyzing Event Streams (2011)

Event-based systems are increasingly gaining widespread attention for applications that require integration with loosely coupled and distributed systems for time-critical problems such as closed loop decision-making on operative levels with low latency. In this paper, we present the event processing language EAExpression for concisely defining event stream operations, such as filter conditions or formulas for calculating scores or measures. EAExpression is an expressive and easy-to-understand language for accessing and evaluating events both during the design phase (e.g. validating application artifacts such as rules, formulas and queries) as well as during the runtime of an event processing application. The language design aims particularily at business users by offering a user-friendly syntax and a comprehensive set of user functions. We demonstrate examples for typical applications of the language in various event processing components, such as in event-driven rules and business intelligence applications.
Controlling Ultra Wide Band Transmissions from a Wireless Micromachined Geiger Counter (2006)

This paper reports a parametric study of the wireless spectrum generated by discharge-based devices with focus specifically on micromachined Geiger counters as a function of the packaging, biasing circuitry, and sample isotope. Experiments are conducted with discharge devices attached to commercial high voltage (HV) packages with hermetic sealing capabilities. Influences of packaging as well as isotope type are studied and reported. Preliminary results show that current discharges emit RF spectra spanning a bandwidth greater than 3 GHz, which extends into the ultra wideband (UWB) window (from 100 MHZ to 10.6 GHz) that decreases in intensity with increasing observer distance.
620. Oral β-Lactamase Therapies Prevent Microbiome Damage and Attenuate Antibiotic Resistance From IV and Oral Antibiotics in Large Animal Models of Antibiotic-Mediated Gut Dysbiosis (2018)

Antibiotics can damage the gut microbiome leading to overgrowth of pathogens and provide selective pressure for emergence of antibiotic resistance. SYN-004 (ribaxamase) is a clinical-stage β-lactamase formulated for oral delivery intended to degrade certain β-lactam antibiotics in the GI tract to preserve the gut microbiome. Ribaxamase was evaluated in a phase 2b clinical study that met its primary endpoint of significantly reducing C. difficile infection in patients treated with IV ceftriaxone and demonstrated protection of the gut microbiome with reduced emergence of antibiotic resistance. Ribaxamase is intended for use with IV penicillins and cephalosporins, but does not degrade carbapenems. Β-lactamase-mediated microbiome protection was expanded to include oral and carbapenem antibiotics. For use with oral β-lactams, a ribaxamase formulation, SYN-007, was engineered for release in the lower small intestine, distal to the site of antibiotic absorption. For use with IV carbapenems, SYN-006, a novel metallo-β-lactamase, was formulated for oral delivery. SYN-007 (10 mg, PO, TID) was evaluated in dogs treated with oral amoxicillin (40 mg/kg, PO, TID) for 5 days. SYN-006 (50 mg, PO, QID) was evaluated in pigs treated with ertapenem (30 mg/kg, IV, SID) for 4 days. Serum antibiotic levels were measured and fecal DNA whole-genome shotgun sequence analyses were performed. In dogs and pigs, systemic antibiotic levels were not significantly different ±SYN-007 or SYN-006. Fecal DNA metagenomics analyses demonstrated that oral amoxicillin and IV ertapenem resulted in significant changes to the gut microbiome. SYN-007 and SYN-006 attenuated microbiome damage and reduced emergence of antibiotic resistance. Ribaxamase, SYN-007, and SYN-006 have the potential to protect the commensal gut microbiota from antibiotic-mediated collateral damage and to mitigate emergence and spread of antibiotic resistance, thereby broadening the utility of this prophylactic approach to include all classes of β-lactam antibiotics, delivered both systemically and orally. Antibiotic inactivation represents a new paradigm for preservation of the gut microbiome and reduction of antibiotic resistance. S.

Widely bandgap tunable amorphous Cd–Ga–O oxide semiconductors exhibiting electron mobilities ≥10 cm2 V−1 s−1 (2015)

Amorphous oxide semiconductors exhibit large electron mobilities; however, their bandgaps are either too large for solar cells or too small for deep ultraviolet applications depending on the materials system. Herein, we demonstrate that amorphous Cd–Ga–O semiconductors display bandgaps covering the entire 2.5–4.3 eV region while maintaining large electron mobilities ≥10 cm2 V−1 s−1. The band alignment diagram obtained by ultraviolet photoemission spectroscopy and the bandgap values reveal that these semiconductors form type-II heterojunctions with p-type Cu2O, which is suitable for solar cells and solar-blind ultraviolet sensors.
Acquired T‐helper 1 Lymphocyte Anergy Following Infection withMycobacterium ulcerans (2003)

We describe a patient with acquired T-helper lymphocyte anergy to mycobacteria following infection with Mycobacterium ulcerans. Before infection, the patient's peripheral blood mononuclear cells responded to in vitro stimulation with M. ulcerans by producing Th1 cytokines, but, after she developed an ulcer, the response was shifted toward production of Th2 cytokines. Immunomodulatory therapy may be an effective intervention for Buruli ulcer.
MAXIMA: Observations of the Cosmic Microwave Background Anisotropy on Angular Scales of 10' to 5 Degrees (2000)

We discuss the status of our analysis of the data obtained from the first flight of the MAXIMA balloon borne experiment. The flight (MAXIMA-1) took place in August of 1998 from the National Scientific Ballooning Facility in Palestine, Texas. During the four hour flight we mapped a 124 deg2 section of the sky which has extremely low galactic dust contamination. The combination of the beam size and scan strategy make MAXIMA sensitive to CMB fluctuations on a range of angular scales from 10 arcmin to 5 degrees. The instrument consists of a Gregorian telescope with a 1.3 m primary mirror and a receiver housing a 16 element bolometer array cooled to 100 mK. Observations were made at 3 frequency bands centered on 150, 240, and 410 GHz. The results presented will include maps of the CMB anisotropy at 150 GHz. We will also briefly describe the second MAXIMA flight that took place in June of 1999 and our plans for the future. During the second flight we observed 230 deg2 of sky with very low galactic dust contamination. About 20% of this region overlaps the MAXIMA-1 map. The MAXIMA experiment is supported by NASA through grants NAG5-4454, and NAG5-3941, and by the Center for Particle Astrophysics, a National Science Foundation Science and Technology Center operated by the University of California, Berkeley, under Cooperative Agreement No. AST-9120005.
