Mobility-Aware Transmit Beamforming for Ultra-Dense Networks With Sparse Feedback (2018)

The network densification brings favored channel gain. However, its performance is limited by the increased interference and feedback overhead. In this paper, we focus on the channel state information (CSI) measure error induced by feedback delay and study the effect of the uplink feedback on the downlink transmission performance in ultra-dense networks (UDNs). Using a mobility-aware sparse feedback scheme (MSFS), we analyze the feedback transmission delay and feedback waiting delay separately, considering the impact of CSI feedback probability and measurement range. To capture the effect of proposed MSFS, the coverage probability for a typical mobile user is derived, where the imperfect-CSI-based zero-forcing precoding is employed to mitigate the severe inter-cell interference in UDNs. Numerical results reveal that MSFS succeeds in providing the effective CSI for downlink precoding while keeping a lower feedback load, and the optimal feedback probability and measurement range are provided for diverse mobility cases and different network densities.
INFLUENCE OF TRANSGLUTAMINASE-INDUCED CROSS-LINKING ON IN VITRO DIGESTIBILITY OF SOY PROTEIN ISOLATE (2006)

The influence of covalent cross-linking by microbial transglutaminase (MTGase) on the sequential in vitro pepsin and trypsin digestion process and the digestibility of soy protein isolate (SPI), was investigated by sodium dodecylsulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and nitrogen release analyses. Various subunits of β-conglycinin and acidic subunits of glycinin were cross-linked by MTGase to form high molecular weight (MW) biopolymers, while basic subunits of glycinin were unaffected. SDS-PAGE analysis indicated that the cross-linking mainly affected in vitro pepsin digestion pattern of various subunits of β-conglycinin, while the trypsin digestion pattern of native SPI was nearly unaffected. Nitrogen release analysis showed that the in vitro pepsin or/and trypsin digestibility of native SPI (at the end of pepsin or trypsin ingestion) was significantly decreased (P ≤ 0.01) by the MTGase treatment (for more than 2 h). The cross-linking by MTGase also significantly decreased the in vitro digestibility of preheated SPI. These results suggest that the cross-linking by means of transglutaminase may negatively affect the nutritional properties of food proteins.
Quantitative assessments reveal improved neuroscience engagement and learning through outreach (2019)

Lack of resources and exposure to neuroscience in K-12 education has resulted in a limited number of K-12 students pursuing higher education in the field. Meanwhile, the rapid expansion of the field of neuroscience has encouraged many higher educational institutes to offer neuroscience majors. This has opened up the opportunity to engage faculty, as well as graduate and undergraduate students in bringing the most needed knowledge and awareness about neuroscience into K-12 classrooms. However, undergraduate neuroscience curricula have limited formal opportunities to engage in outreach, and few existing programs have assessments to determine their effectiveness. To address these needs, we developed quantitative assessment tools that complement an existing neuroscience outreach program-Project Brainstorm-at the University of California, Los Angeles (UCLA). 29 UCLA undergraduates enrolled in the 2016 and 2017 programs participated in this study, along with 298 K-12 students from local schools across the Los Angeles area. In undergraduate students, we assessed (a) improvement in students' teaching/communication abilities across the course of the outreach program, and (b) confidence in explaining neuroscience topics and interest in pursuing teaching career. In K-12 students, we evaluated (a) knowledge gain in neuroscience topics and (b) interest in pursuing higher education. Overall, Project Brainstorm showed significant improvement in all the above-mentioned categories. The assessment tools and data presented here provide a data-driven approach for optimizing neuroscience outreach programs and can easily be adapted to other outreach programs within neuroscience and in other STEM fields.

This report describes technical progress of research and development efforts aimed at producing superconducting components in the Y-Ba-Cu, (Bi,Pb)-Sr-Ca-Cu,(Tl,Pb, Bi)-(Ba,Sr)-Ca-Cu, and Hg-Ba-Ca-Cu-O oxide systems. Topics discussed are synthesis and heat treatment of high-T{sub c} superconductors; formation of monolithic and composite wires, tapes, and coils, characterization of structures and superconducting and mechanical properties; fabrication and properties of films; and development of properties of films; and development of prototype components. Collaborations with industry and academia are documented.
Evaluation of tissue polypeptide specific antigen, CYFRA 21-1, and carcinoembryonic antigen in nonsmall cell lung carcinoma (1998)

These findings suggest that, for NSCLC patients, CYFRA 21-1 and TPS are significant prognostic factors and effective monitors of therapy. The combined use of these cytokeratin markers may provide additional information for prognosis.
Comparison of Aerosol Sampling with Shrouded and Unshrouded Probes (1995)

Abstract Continuous air monitoring is a requirement for many of the stacks and ducts in the nuclear industry. Aerosol sampling systems for these applications should have minimal errors, even though there are variations in operating conditions. In this context a shrouded probe with a nominal sampling rate of 57 L/min (2 fr3/min) was designed and its performance compared with unshrouded sharp-edged probes over a range of particle sizes (5–15 µm aerodynamic diameter [AD]), free stream velocities (9–21 m/sec) and yaw angles (0°–22.5°). Transmission of aerosol through unshrouded probes was typically 60% or less because of internal wall losses, whereas the intrinsic characteristics of the shrouded probe provided a near-unity transmission ratio for the diverse range of operating conditions. When 10-µm AD particles were sampled with a shrouded probe over the previously noted range of free stream velocities and yaw angles, the transmission ratios varied from 0.82 to 1.08. Wall losses in the shrouded probe were generally about one-half of those in the sharp-edged unshrouded probes. The transmission ratio of the shrouded probe was determined for a ±25% variation in sampling flow rate. The results showed values of 0.9 to 1.0 for operation with 10-µm AD aerosol particles at a velocity of 21 m/sec.
PREDICTORS OF SEVERE ADVERSE EVENTS AFTER ENDOSCOPIC ULTRASOUND THROUGH-THE-NEEDLE BIOPSY OF PANCREATIC CYSTS: A MACHINE LEARNING APPROACH (2022)

Aims A non-negligible rate of severe adverse events (AEs) was observed with endoscopic ultrasound (EUS) through-the-needle biopsy (TTNB) of pancreatic cystic lesions (PCLs); however, predictive factors are still unknown. We aimed at identifying the hierarchic interaction among independent predictors for TTNB-related AEs and to generate a prognostic model using recursive partitioning analysis (RPA).
Fibrodysplasia Ossificans Progressiva Why Do Some People Have Two Skeletons? (1997)

Fibrodysplasia ossificans progressiva (FOP) is one of the rarest genetic conditions known. People who have this disorder essentially form two skeletons: a normal one during embryogenesis and a heterotopic one after birth. Although the general phenotype of the disease, including the presence of congenital malformations of the great toes, is constant among individuals, there is wide variation in the severity of the disorder. Studies to identify the cause of FOP currently are focused on a candidate gene approach. Bone morphogenetic proteins (BMPs) are bone-inducing morphogens that are involved in the developmental organization of the skeleton and are excellent candidate genes for disorders of heterotopic osteogenesis. We recently have demonstrated that overexpression of BMP 4 in cells from patients who have FOP is associated with this disorder. We are continuing to investigate the role of BMP-4 in the pathophysiology of FOP. An analysis of the genetic and cellular pathways that are activated ectopically in patients who have FOP will help elucidate how bone forms and grows and will lead to more effective treatments of orthotopic and heterotopic osteogenesis.

Conflict on interprofessional primary health care teams – can it be resolved? (2010)

Increasingly, primary health care teams (PHCTs) depend on the contributions of multiple professionals. However, conflict is inevitable on teams. This article examines PHCTs members' experiences with conflict and responses to conflict. This phenomenological study was conducted using in-depth interviews with 121 participants from 16 PHCTs (10 urban and 6 rural) including a wide range of health care professionals. An iterative analysis process was used to examine the verbatim transcripts. The analysis revealed three main themes: sources of team conflict; barriers to conflict resolution; and strategies for conflict resolution. Sources of team conflict included: role boundary issues; scope of practice; and accountability. Barriers to conflict resolution were: lack of time and workload; people in less powerful positions; lack of recognition or motivation to address conflict; and avoiding confrontation for fear of causing emotional discomfort. Team strategies for conflict resolution included interventions by team leaders and the development of conflict management protocols. Individual strategies included: open and direct communication; a willingness to find solutions; showing respect; and humility. Conflict is inherent in teamwork. However, understanding the potential barriers to conflict resolution can assist PHCTs in developing strategies to resolve conflict in a timely fashion.
Process of Drug Release with Oral Dosage Forms with a Lipidic Gelucire Matrix (1997)

The process of drug release out of dosage forms made of the drug dispersed in a lipidic Gelucire is considered. The process is based on the following three ideas: first, the liquid dissolves the drug in contact with it and occupies its previous place; second, the drug diffuses out of the dosage form through the liquid located in it, and third, the diffusivity of the drug varies with the concentration of the liquid in an exponential way. These assumptions are drawn from the following experimental observations: no change in dimension of the dosage form takes place; the amount of drug release after a long time is greater than that evaluated with a constant diffusivity. Good agreement is obtained between the kinetics of drug release obtained either by calculation or from experiments using in vitro tests.
Central venous catheter placement by an interventional radiology unit: An Australian experience (2007)

The aim of this retrospective study was to analyse the outcomes of central venous catheter (CVC) placement carried out by an interventional radiology unit. A review of our hospital records identified 331 consecutive patients who underwent insertion of a tunnelled or non-tunnelled CVC between January 2000 and December 2004. Key outcome measures included the technical success rate of CVC insertion and the percentage of immediate (<24 h), early (24 h-30 days) and late (>30 days) complications. A total of 462 CVCs were placed under radiological guidance, with an overall success rate of 98.9%. Immediate complications included one pneumothorax, which was diagnosed 7 days after subclavian CVC insertion, and eight episodes of significant haematoma or bleeding within 24 h of CVC insertion. No cases were complicated by arterial puncture or air embolus. Catheter-related sepsis occurred in 2% of non-tunnelled CVC and 8.9% of tunnelled CVC. The overall incidence of catheter-related sepsis was 0.17 per 100 catheter days. As the demand for chemotherapy and haemodialysis grows with our ageing population, interventional radiology suites are well placed to provide a safe and reliable service for the placement of central venous access devices.
Deep neural network architectures for forecasting analgesic response (2016)

Response to prescribed analgesic drugs varies between individuals, and choosing the right drug/dose often involves a lengthy, iterative process of trial and error. Furthermore, a significant portion of patients experience adverse events such as post-operative urinary retention (POUR) during inpatient management of acute postoperative pain. To better forecast analgesic responses, we compared conventional machine learning methods with modern neural network architectures to gauge their effectiveness at forecasting temporal patterns of postoperative pain and analgesic use, as well as predicting the risk of POUR. Our results indicate that simpler machine learning approaches might offer superior results; however, all of these techniques may play a promising role for developing smarter post-operative pain management strategies.
Design and Test of a 6.7-GHz Coaxial Bragg Reflector (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> A coaxial line periodically loaded by circular disks on the inner conductor is designed and constructed to act as a Bragg reflector in the 4.0–10.0-GHz frequency range. This is achieved by placing ten disks (0.35 cm thick and 6.22 cm in diameter) equally spaced by the periodic distance of 1.8 cm on a coaxial waveguide with inner and outer diameters of 6.90 and 4.22 cm, respectively. Analytical discussion and 2- and 3-D computer simulations demonstrate a bandgap of 5.6 GHz centered at the 6.7-GHz design frequency in close agreement with experiments on a periodic structure made from stainless steel. </para>
T‐ AND B‐CELL INTERACTIONS IN AUTOIMMUNE SYNDROMES (1975)

We have reviewed briefly some of the individual capabilities of T and B cells and how these can be modified by interactions between the two cell lines. Evidence that T cells have their own distinct receptors for antigens, yet under certain circumstances may bind IgM or IgG produced by B cells, has been particularly emphasized. The probability that B cells, in turn, may bind the antigen receptor of T-cell origin reflects the balanced nature of an intricate communication system in which interactions between antigens, antigen receptors, and binding sites for these receptors all serve to modulate the integrated functioning of T and B cells. It is suggested that this communication system is disturbed in patients with rheumatoid arthritis; specifically, it is proposed that defective feedback activity of IgG-antigen complexes on activated T cells may exist in some patients and could result in unchecked and harmful T-cell activity in the joint. Therapeutic implications of this idea are mentioned.
Non‐canonical metabolic pathways in the malaria parasite detected by isotope‐tracing metabolomics (2021)

The malaria parasite, Plasmodium falciparum, proliferates rapidly in human erythrocytes by actively scavenging multiple carbon sources and essential nutrients from its host cell. However, a global overview of the metabolic capacity of intraerythrocytic stages is missing. Using multiplex <sup>13</sup> C-labelling coupled with untargeted mass spectrometry and unsupervised isotopologue grouping, we have generated a draft metabolome of P. falciparum and its host erythrocyte consisting of 911 and 577 metabolites, respectively, corresponding to 41% of metabolites and over 70% of the metabolic reaction predicted from the parasite genome. An additional 89 metabolites and 92 reactions were identified that were not predicted from genomic reconstructions, with the largest group being associated with metabolite damage-repair systems. Validation of the draft metabolome revealed four previously uncharacterised enzymes which impact isoprenoid biosynthesis, lipid homeostasis and mitochondrial metabolism and are necessary for parasite development and proliferation. This study defines the metabolic fate of multiple carbon sources in P. falciparum, and highlights the activity of metabolite repair pathways in these rapidly growing parasite stages, opening new avenues for drug discovery.
Morphing Aircraft Technology - New Shapes for Aircraft Design (2006)

Morphing aircraft are multi-role aircraft that change their external shape substantially to adapt to a changing mission environment during flight. This creates superior system capabilities not possible without morphing shape changes. The objective of morphing activities is to develop high performance aircraft with wings designed to change shape and performance substantially during flight to create multiple-regime, aerodynamically-efficient, shape-changing aircraft. Compared to conventional aircraft, morphing aircraft become more competitive as more mission tasks or roles are added to their requirements. This paper will review the history of morphing aircraft, describe a recent DARPA program, recently completed, and identify critical technologies required to enable morphing. As indicated in Figure 1, designing and building aircraft shape changing components is not new. In the past, aircraft have used variable sweep, retractable landing gear, retractable flaps and slats, and variable incidence noses. However, recent work in smart materials and adaptive structures has led to a resurgence of interest in more substantial shape changes, particularly changes in wing surface area and controlled airfoil camber.
A framework for diversifying windows native APIs to tolerate code injection attacks (2007)

We present a framework to prevent code injection attacks in MS Windows using Native APIs in the operating system. By adopting the idea of diversity, this approach is implemented in a two-tier framework. The first tier permutes the Native API dispatch ID number so that only the Native API calls from legitimate sources are executed. The second tier provides an authentication process in case an attacker guesses the first-tier permutation order. The function call stack is back-traced to verify whether the original caller's return address resides within the legitimate process. The process is terminated and an alert is generated when an attack is suspected. Experiments indicate that our approach poses no significant overhead.
Hardware Architecture to Realize Multi-layer Image Processing in Real-time (2007)

Visual data with appropriate processing has very important information for many robotic applications. Usually, people use digital computer to do the image processing, but for complex or copious algorithms, due to the architecture of present CPU-based computing system, it is very time consuming and resource wasting to do these kinds of process. In this paper, we focus on the crucial case - image algorithms with multi-layer processes. In this kind of algorithms, the following process always need to wait the result from the previous step and access the memory very frequently, which cause the timing delay and resource grabbing in general CPU-based system. In order to solve this problem, first we go deep into the data flow in multi-layer image processing. We observe that it has many parallel and pipeline properties without waiting for some unnecessary delay, and fortunately, these properties exactly match with the characteristics of hardware design. For this reason, we propose a novel hardware architecture called visual pipeline to overcome these problems. The combination of the concepts from parallel and pipeline properties in hardware design are used, and finally we use FPGA to implement our architecture. To verify our hardware design, we use multi-scale Harris corner detector as the example, which is also a multi-layer process. Finally, we can show the result running in real-time of multi-layer image processing.

COMPARISON OF PLASMA-CATALYST AND ACTIVE LEAN NOx CATALYST (2000)

A number of NO{sub x} control systems are being discussed for potential application to diesel engines. Unfortunately, it can be difficult to compare systems on an equal basis because data are run under different conditions, or reported against different test cycles, or not shown over a range of operating conditions. In addition, the fuel consumption penalty associated with the NO{sub x} control technologies is not always reported. In this paper, we compare two diesel NO{sub x} aftertreatment systems: (1) Plasma-Catalyst (PC): a nonthermal plasma followed by a catalyst; and (2) Active Lean NO{sub x} Catalyst (ALNC): a NO{sub x} catalyst designed to selectively reduce NO{sub x} using hydrocarbon (HC) in the form of diesel fuel. Fuel is added to the exhaust to increase HC above normal diesel levels. These systems will be described in more detail in this report.
