Radio resource allocation based on dynamic CoMP mode selection for MU-CoMP systems (2014)

Multi-User Coordinated Multi-Point (MU-CoMP) transmission mode is considered as one of the key technologies which offer a good quality of service to low capacity users while maintaining a high spectral efficiency in the system. However, MU-CoMP networks have to determine the total number of users supported by CoMP operation as well as the size of the SDMA (Spatial Division Multiple Access) users' groups permanently. Previous studies often considered static selection criterion and bandwidth reservation for CoMP transmission mode. In this paper, we deal with dynamic CoMP transmission mode selection jointly with bandwidth allocation problem in order to meet the system performance requirements. We propose a new scheme which takes into account the variation of users' quality of service and the total load in the cluster. Significant improvements are obtained in both total system throughput and outage probability in the cluster with our proposed scheme.
Undefined behavior (2012)

System programming languages such as C grant compiler writers freedom to generate efficient code for a specific instruction set by defining certain language constructs as undefined behavior. Unfortunately, the rules for what is undefined behavior are subtle and programmers make mistakes that sometimes lead to security vulnerabilities. This position paper argues that the research community should help address the problems that arise from undefined behavior, and not dismiss them as esoteric C implementation issues. We show that these errors do happen in real-world systems, that the issues are tricky, and that current practices to address the issues are insufficient.

Ambient Backscatter-Assisted Wireless-Powered Relaying (2021)

Internet-of-Things (IoT) is featured with low-power communications among a massive number of ubiquitously-deployed and energy-constrained electronics, e.g., sensors and actuators. To cope with the demand, wireless-powered cooperative relaying emerges as a promising communication paradigm to extend data transmission coverage and solve energy scarcity for the IoT devices. In this paper, we propose a novel hybrid relaying strategy by combining wireless-powered communication and ambient backscattering functions to improve applicability and performance of data transfer. In particular, the hybrid relay can harvest energy from radio frequency (RF) signals and use the energy for active transmission. Alternatively, the hybrid relay can choose to perform ambient backscattering of incident RF signals for passive transmission. To efficiently utilize the ambient RF resource, we design mode selection protocols to coordinate between the active and passive relaying in circumstances with and without instantaneous channel gain. With different mode selection protocols, we characterize the success probability and ergodic capacity of a dual-hop relaying system with the hybrid relay in the field of randomly located ambient transmitters. The analytical and the numerical results demonstrate the effectiveness of the mode selection protocols in adapting the hybrid relaying into the network environment and reveal the impacts of system parameters on the performance gain of the hybrid relaying. As applications of our analytical framework which is computationally tractable, we formulate optimization problems based on the derived expressions to optimize the system parameters with different objectives. The optimal solutions exhibit a tradeoff between the maximum energy efficiency and target success probability.
A Regiospecific Synthesis of Carbazoles via Consecutive Palladium-catalyzed Cross-coupling and Aryne-mediated Cyclization (1993)

A regiospecific synthesis of carbazoles has been developed using palladium-catalyzed cross-coupling of N-(tert-butoxycarbonyl)-2-tributylstannylanilines with 2- or 3-bromochlorobenzene followed by aryne-mediated cyclization as the key reactions. The carbazole alkaloids, glycozolinine and glycozolidine, were synthesized using this procedure

Treatment of a Complex Personality Disorder Using Repeated Doses of LSD—A Case Report on Significant Improvements in the Absence of Acute Drug Effects (2020)

A 39-year-old female patient suffering from severe, treatment-resistant depression and other symptoms associated with a complex personality disorder was admitted to our open psychiatric ward for an experimental treatment with lysergic acid diethylamide (LSD). The substance was administered in repeated weekly and ascending doses. Curiously, there were no substantial acute subjective effects of the drug despite adequate dosing, which was also confirmed by plasma drug concentration monitoring. However, the patient showed rapid and significant improvement with most notable changes in depressed mood, emotional instability, loss of energy, and suicidal ideations. Additionally, the SCL-90 questionnaire indicated significant decreases in global severity and in various psychopathological subscales. Improvements persisted for ~7 days after each administration. Due to the severe course of the illness and the resistance to previous treatment it was decided to continue this experimental approach with weekly repeated doses of LSD. The patient will be observed closely with regard to somatic and mental side effects. Two features of this case are remarkable: Firstly, administration of LSD was associated with significant improvements in various symptoms of a condition usually difficult to treat. Secondly, symptom reductions occurred in the absence of acute drug effects. Therefore, the mechanism of action seemed to deviate from the concept that improvements after administration of drugs like LSD are due to experiences during the acute drug effects. This case might indicate that LSD can induce rapid but transient beneficial effects on several psychopathological symptoms. The time course of these improvements resembled antidepressant effects seen after administration of ketamine.
Midazolam Versus Diazepam for the Treatment of Status Epilepticus in Children and Young Adults: A Meta‐analysis (2010)

Non-IV midazolam, compared to non-IV or IV diazepam, is safe and effective in treating SE. Comparison to lorazepam, evaluation in adults, and prospective confirmation of safety and efficacy is needed.
Sweep Effects on Fan-Intake Aerodynamics at High Angle of Attack (2021)

Abstract Sweep in a transonic fan is conventionally used to reduce design point losses by inclining the passage shock relative to the incoming flow. However, future low pressure ratio fans operate to lower Mach numbers meaning the role of sweep at cruise is diminished. Instead, sweep might be repurposed to improve the performance of critical high Mach number off-design conditions such as high angle of attack (AOA). In this paper, we use unsteady computational fluid dynamics to compare two transonic low pressure ratio fans, one radially stacked and one highly swept, coupled to a short intake design, at the high AOA flight condition. The AOA considered is 35°, which is sufficient to separate the intake bottom lip. The midspan of the swept fan was shifted upstream to add positive sweep to the outer span. Based on previous design experience, it was hypothesised the swept fan would reduce transonic losses when operating at high AOA. However, it was found the swept fan increased the rotor loss by 24% relative to the radial fan. Loss was increased through two key mechanisms. i) Rotor choking: flow is redistributed around the intake separation and enters the rotor midspan with high Mach numbers. Sweeping the fan upstream reduced the effective intake length, which increased the inlet relative Mach number and amplified choking losses. ii): Rotor-separation interaction (RSI): the rotor tip experiences low mass flow inside the separation, which increases the pressure rise across the casing to a point where the boundary layer separates. The swept fan diffused the casing streamtube, causing the casing separation to increase in size and persist in the passage for longer. High RSI loss indicated the swept fan was operating closer to the rotating stall point.
Cerium Phosphate–Cerium Oxide Heterogeneous Composite Nanozymes with Enhanced Peroxidase-Like Biomimetic Activity for Glucose and Hydrogen Peroxide Sensing (2018)

In the present work, we focus on the development of CePO<sub>4</sub>-CeO<sub>2</sub> composite nanorods with peroxidase mimetic activity for the sensitive detection of hydrogen peroxide and glucose. The Ce<sup>3+</sup>/PO<sub>4</sub><sup>3-</sup> molar ratio (CP10:1, CP5:1, CP2:1) in the hydrothermal reaction controlled the formation of pure CePO<sub>4</sub>, CePO<sub>4</sub>-CeO<sub>2</sub> composite nanozymes with different percentages of CeO<sub>2</sub>, and its crystal structure. A higher Ce<sup>3+</sup>/PO<sub>4</sub><sup>3-</sup> molar ratio (CP10:1 or CP5:1) was required to obtain CePO<sub>4</sub>-CeO<sub>2</sub> composite nanostructure, while a lower Ce<sup>3+</sup>/PO<sub>4</sub><sup>3-</sup> molar (CP2:1) ratio was sufficient to fabricate pure CePO<sub>4</sub> nanorods. In the presence of hydrogen peroxide, the prepared nanozymes catalyze the oxidation of chromogenic substrate 3,3',5,5'-tetramethylbenzidine (TMB). Steady state kinetic analysis based on the Michaelis-Menten model revealed that CP10:1 showed excellent affinity toward the TMB ( K<sub>m</sub> = 0.236 mM and V<sub>max</sub> = 8.78 × 10<sup>-8</sup> M s<sup>-1</sup>) in comparison to the catalytic activity of CP5:1 and CP2:1 and horseradish peroxidase ( K<sub>m</sub> = 0.434 mM and V<sub>max</sub> = 10.0 × 10<sup>-8</sup> M s<sup>-1</sup>). The superior peroxidase activity of CePO<sub>4</sub>-CeO<sub>2</sub> composite nanozymes can be ascribed to the enhanced redox switching between Ce<sup>3+</sup> ↔ Ce<sup>4+</sup> sites from the CePO<sub>4</sub> and CeO<sub>2</sub> lattice, respectively. The colorimetric detection of hydrogen peroxide and glucose showed a linear response around 150 μM concentration with the limits of detection (LOD) of 2.9 and 4.1 μM, respectively.
Cell cycle dependent gene expression in quiescent stimulated and asynchronously cycling arterial smooth muscle cells in culture (1992)

The expression of a set of cell cycle dependent (CCD) genes (c-fos, c-myc, ornithine decarboxylase (ODC), and thymidine kinase (TK)) was comparatively studied in cultured arterial smooth muscle cells (SMC) during exit from quiescence and exponential proliferation. These genes, which were not expressed in quiescent SMC, were chronologically induced after serum stimulation. c-fos mRNA were rapidly and transiently expressed very early in the G1 phase; c-myc and ODC peaked a few hours after serum stimulation and then remained at an intermediary level throughout the first cell cycle; TK mRNA and activity then appeared at the G1/S boundary and peak in G2/M phases. Except for c-fos, the other genes were also expressed in asynchronously cycling SMC (ACSMC); their expression was studied in elutriated subpopulations representative of cell cycle progression. c-fos mRNA were undetectable in any sorted subpopulations, even in the pure early G1 population. Despite a slight increase as the cell cycle advanced, c-myc and ODC genes were expressed throughout the ACSMC cell cycle. A faint TK activity was found in G1 subpopulations and increased in populations enriched in other phases; in contrast, TK mRNA remained highly expressed in all elutriated subpopulations. This study demonstrates significant modulations in CCD gene expression between quiescent stimulated and asynchronously cycling SMC in culture. This suggests that the events occurring during the emergence of SMC from quiescence are probably different from those in the G1 phase of ACSMC.
Factors Influencing Environmental Strategies among Food Service Franchisors in Taiwan (2008)

Research related to environmental management in the Taiwan food service industry is still very limited. This research aims to study how corporate (head office) level decision makers in the food service chains recognize the impact of environmental issue on their business, and what factors might influence them putting this issue into firms' strategic plans. An in-depth case study in which each of the motivating factors and environmental strategies were studied, and the associated relationships between them and the key motivating factors were able to be determined. In conclusion, the results of this study found external factors, competitive advantage and public concern, rather than the government's environmental policy, are the key driving forces toward environmental strategies or activities for large food service chains with strong capability, and top management commitment. From this research new hypotheses for further testing and refinement can be developed. An example of one such hypothesis is provided.
A dynamic bayesian network click model for web search ranking (2009)

As with any application of machine learning, web search ranking requires labeled data. The labels usually come in the form of relevance assessments made by editors. Click logs can also provide an important source of implicit feedback and can be used as a cheap proxy for editorial labels. The main difficulty however comes from the so called position bias - urls appearing in lower positions are less likely to be clicked even if they are relevant. In this paper, we propose a Dynamic Bayesian Network which aims at providing us with unbiased estimation of the relevance from the click logs. Experiments show that the proposed click model outperforms other existing click models in predicting both click-through rate and relevance.
Efficient source for the production of ultradense deuterium D(-1) for laser-induced fusion (ICF) (2011)

A novel source which simplifies the study of ultradense deuterium D(-1) is now described. This means one step further toward deuterium fusion energy production. The source uses internal gas feed and D(-1) can now be studied without time-of-flight spectral overlap from the related dense phase D(1). The main aim here is to understand the material production parameters, and thus a relatively weak laser with focused intensity ≤10(12) W cm(-2) is employed for analyzing the D(-1) material. The properties of the D(-1) material at the source are studied as a function of laser focus position outside the emitter, deuterium gas feed, laser pulse repetition frequency and laser power, and temperature of the source. These parameters influence the D(-1) cluster size, the ionization mode, and the laser fragmentation patterns.
[Immunohistochemical study of oncogene-related products in human gastrointestinal malignancies--expression of ras p 21, fes p 85 and EGF receptor]. (1986)

An immunohistochemical examination by the avidin-biotin-peroxidase complex method was carried out to assess the expression of oncogene-related products, i.e., ras p 21 protein, fes p 85 protein and epidermal-growth-factor (EGF) receptors, in human gastrointestinal malignancies. The presence of ras p 21, fes p 85 and EGF receptors was detected in 48%, 62%, and 62% of 29 colorectal carcinomas and in 65%, 65% and 40% of 20 gastric cancers, respectively. More than one oncogene protein was demonstrated in 18 of 29 colorectal carcinomas and in 10 of 20 gastric cancers. These results suggest that multiple oncogenes are important in the occurrence and progress of gastrointestinal malignancies.
Design optimization of high voltage bushing using electric field computations (2006)

This paper illustrates the use of electric field computation to optimize the design of gas filled high voltage composite bushings. The United States Navy employs these bushings in high power very low frequency/low frequency transmitting stations. Commercially available 2D and 3D computational packages based on the boundary element method were employed to analyze the electric fields. The optimized design uses both internal and external elements for electric stress grading at critical parts of the bushing. It has been shown that the location and magnitude of the maximum electric field have been optimized which should result in a substantially higher corona free operating voltage

Evolution of diagnostic approaches in betalactam hypersensitivity (2017)

Betalactams are the most widely used drugs against infections and the primary cause of antibiotic hypersensitivity reactions. Reaction patterns for different betalactams have been changing in accordance with consumption trends, and vary among countries. As a consequence, in vivo and in vitro tests have had to change with to keep up with new tendencies. Areas covered: This review is focused on advances in betalactam hypersensitivity diagnosis. Changes in in vivo methods have been limited to the inclusion of new haptens. In contrast, major progress has been achieved for in vitro tests since the 1960s, from the first description of immunoassays, the basophil activation test and the lymphocyte transformation test, to the more sophisticated assays developed in last years. Expert commentary: Issues with diagnosis are related to test sensitivity. In vivo tests show higher sensitivity, however they can be risky, especially in severe and life-threatening reactions. Therefore, we believe that in vitro tests should be the preferred method. Current efforts are under way to enhance their sensitivity. Only multidisciplinary approaches involving immunology, proteomics, nanotechnology and chemistry can help us to fully understand conjugate structures and mechanisms involved in hypersensitivity reactions to betalactams, and consequently lead to advances in in vitro methods.
The Influence of Thyroid Hormones on In Vitro Erythropoiesis (1977)

A B S T R A C T The erythropoietic effect of various thyroid hormones has been studied using erythroid colony formation by canine marrow cells. Although erythropoietin was required for colony growth, physiologic levels ofthyroid hormones significantly enhanced colony numbers. The order of potency of the thyroid compounds in their in vitro erythropoietic effect paral- lels their known calorigenic potency in vivo, suggesting that the in vitro effect is physiologically relevant. A series ofstudies linked the mechanism ofthyroid action to adrenergic receptors on responsive cells. Proprano- lol, a global ,8-blocker, inhibited thyroid hormone- responsive erythroid colonies. When adrenergic antag- onists having different blocking characteristics were added to culture, the thyroid hormone effect was blocked by those compounds having ,82-subspecificity.
A simulator with a plug-in frame structure for the thin-wire antenna analysis. (2002)

In this paper, the antenna analysis simulator made by the object oriented programming was reported. This simulator based on a plug-in frame structure was composed by GUI, a FDTD solver and a Moment Method solver. These elements were combined in the plug-in frame by the API. This simulator can work with the solvers using the FDTD and the Moment Method under the identical GUI. Numerical results from each analysis method for a thin-wire antenna were compared.
Discharge patterns in the subtralamic nucleus and substantia nigra during deep brain stimulator implants (2005)

8 patients affected by Parkinson's disease underwent implantation of stimulating electrodes in both subthalamic nuclei (STN). The stereotactic track was explored by a 1 M/spl Omega/ microelectrode and recordings were taken at different depths, from 5 mm before down to 5 mm beyond the target, with a 1 mm step. At rest, in 8 out of the 16 successful tracks, spikes were recognizable in correspondence to the STN and in 2 in correspondence to the substantia nigra (SN) beyond the target. Spikes were detected by a matched filtering and threshold algorithm. The spike shape was analyzed by the rise time (0.199/spl plusmn/0.064 msec, mean/spl plusmn/SD, in the STN), decay time (0.345/spl plusmn/0.114 msec) and bandwidth (1.612/spl plusmn/0.622 kHz, -3 dB). The discharge patterns were analyzed through the inter spike interval (ISI) histogram, the conditional intensity function (CIF) and the spectrum of counts. The mean interval was 33.3/spl plusmn/11.9 msec. Apart a single case of rhythmicity (1.65 Hz), the discharge pattern in the STN was always Poisson like with or without the presence of short bursts, as revealed by a flat CIF. Rhythmic patterns were found in SN.
BF3·OEt2 mediated metal-free one-pot sequential multiple annulation cascade (SMAC) synthesis of complex and diverse tetrahydroisoquinoline fused hybrid molecules (2016)

A highly efficient and distinct BF3·OEt2 mediated metal-free SMAC protocol for the synthesis of complex and diverse hybrid molecules viz. indazole fused tetrahydroisoquinolinoquinoxalines, and tetrahydroisoquinolinodiazepine has been developed. The transformation is based on sequential cascade processes involving 2H-indazole formation and deprotection Pictet-Spengler cyclization steps in one-pot fashion. The protocol demonstrates the utility of sequential multiple annulations in a cascade fashion. The present one-pot protocol uses the Solid State Melt Reaction (SSMR) strategy for the synthesis of the intermediate 2H-indazole. The method is operationally simple and represents a new approach for C-C, three C-N and N-N bond formation with a wide substrate scope.
