Synthesis and Thermal Stability of the Solid Solution AFeO2 (A = Ba, Sr, Ca) (2010)

We have studied the A-site substitution effect on the structural, thermal, and magnetic properties of the infinite layer iron oxide AFeO(2) (A = alkali-earth elements) with an FeO(4) square-planar coordination. Together with the previous study showing a total substitution by Ca, Ba substitution is found to be tolerable up to 30%, presenting almost the same substitutional range as that found in ACuO(2) under high pressure. Notably, Ba substitution shows little influence on the magnetic properties, in contrast to expectations from first principles calculations. The temperature at which oxidation to an AFeO(2.5) phase occurs and its transformation rate show a wide variation tunable solely by the out-of-plane distance.
Algorithms for Faster and Larger Dynamic Metropolis Simulations (2003)

In dynamic Monte Carlo simulations, using for example the Metropolis dynamic, it is often required to simulate for long times and to simulate large systems. We present an overview of advanced algorithms to simulate for longer times and to simulate larger systems. The longer‐time algorithm focused on is the Monte Carlo with Absorbing Markov Chains (MCAMC) algorithm. It is applied to metastability of an Ising model on a small‐world network. Simulations of larger systems often require the use of non‐trivial parallelization. Non‐trivial parallelization of dynamic Monte Carlo is shown to allow perfectly scalable algorithms, and the theoretical efficiency of such algorithms are described.
Magnesium Complexes Bearingη2-Pyrazolato Ligands (1998)

Despite the small size of the magnesium ion, η<sup>2</sup> -bound pyrazolato ligands are found in complexes 1-3. These complexes provide new insight into the design of volatile Group 2 metal complexes for use in chemical vapor deposition processes.
Construction of a large-size four plane micromegas detector (2014)

In view of the use of micromegas detectors for the upgrade of the ATLAS muon system, we have constructed a detector quadruplet with an area of 0.5 m 2 per plane serving as prototypes for future ATLAS chambers. It is based on the resistive-strip technology and thus spark tolerant. We present the detector concept, the experience with the detector construction, and the first evaluation of the detector with cosmic rays. The quadruplet will be installed in ATLAS in fall 2014, to be operated in real-experiment conditions during the LHC Run2.
MetricOpt: Learning to Optimize Black-Box Evaluation Metrics (2021)

We study the problem of directly optimizing arbitrary non-differentiable task evaluation metrics such as misclassification rate and recall. Our method, named MetricOpt, operates in a black-box setting where the computational details of the target metric are unknown. We achieve this by learning a differentiable value function, which maps compact task-specific model parameters to metric observations. The learned value function is easily pluggable into existing optimizers like SGD and Adam, and is effective for rapidly finetuning a pre-trained model. This leads to consistent improvements since the value function provides effective metric supervision during finetuning, and helps to correct the potential bias of loss-only supervision. MetricOpt achieves state-of-the-art performance on a variety of metrics for (image) classification, image retrieval and object detection. Solid benefits are found over competing methods, which often involve complex loss design or adaptation. MetricOpt also generalizes well to new tasks and model architectures.
Abstract P1057: Implementing A Novel FRET-Based Myofilament Activation Biosensor To Interrogate Dynamic Cardiac Sarcomere Performance With Small Molecule And Genetic Manipulations During A Physiological Twitch (2022)

The sarcomere is the functional unit of cardiac muscle contraction. Understanding the precise mechanisms regulating this contraction is key to advancing insights into cardiomyopathies, which affect as many as 1 in 500 adults. Previous work has identified many key sarcomeric components and modulators necessary for the activation of contraction through inter-myofilament signaling. Although these studies have provided valuable information, the majority of this work has been done using in vitro protein recombination or permeabilized muscle. While informative, these systems lack significant physiological features of muscle, including load and intact excitation-contraction coupling mechanisms. Therefore, a large gap exists in the ability to monitor the time-sensitive stepwise physiological mechanism of muscle sarcomere activation in an intact system in real time. In order to further advance the study of sarcomere activation in both physiological and disease states, a cardiac specific myofilament-targeted FRET based biosensor has been designed and validated. The sarcomere activation biosensor reports myofilament dynamics during physiological twitch contractions in live cardiac muscle in real time in the form of simultaneous force and fluorescence measurements. This allows FRET-detection of the global conformational changes in TnC, a nexus point able to integrate many sarcomere-activating ligands, to be observed. From these changes in fluorescence the ensemble of events which lead to sarcomere activation and muscle contraction can be tracked. Data show regulatory ligands of myofilament activation in real time during a physiological twitch contraction. Currently, the biosensor is being utilized to investigate changes in sarcomere activation driven through the use of small molecules, including myosin inhibitor Mavacamten and TnC-TnI inhibitor W7, and those seen in MyBP-C knockout mice. The results of these investigations will be discussed.

Study on satellite broadcasting scheduling based on Particle Swarm Optimization algorithm (2009)

The efficiency of utilizing the satellite communications resource and system can be improved by optimizing the satellite broadcasting scheduling with genetic algorithm. However drawbacks such as complicated genetic operation, tardy convergent speed and the aptness to sink into local minimum within the genetic algorithm (GA) have encouraged a satellite broadcasting scheduling approach for resolving the scheduling model. The approach was based on the particle swarm optimization (PSO) algorithm which involved in processes such as constructing the model of satellite broadcasting scheduling, initialization of the particles and particle optimization. It has been shown by simulation analysis that satellite broadcasting scheduling based on the PSO algorithm was feasible and its optimization result was significant.
Multi-Gbit/s optical phase chaos communications using a time-delayed optoelectronic oscillator with a three-wave interferometer nonlinearity (2017)

We propose a chaos communication scheme based on a chaotic optical phase carrier generated with an optoelectronic oscillator with nonlinear time-delay feedback. The system includes a dedicated non-local nonlinearity, which is a customized three-wave imbalanced interferometer. This particular feature increases the complexity of the chaotic waveform and thus the security of the transmitted information, as these interferometers are characterized by four independent parameters which are part of the secret key for the chaos encryption scheme. We first analyze the route to chaos in the system, and evidence a sequence of period doubling bifurcations from the steady-state to fully developed chaos. Then, in the chaotic regime, we study the synchronization between the emitter and the receiver, and achieve chaotic carrier cancellation with a signal-to-noise ratio up to 20 dB. We finally demonstrate error-free chaos communications at a data rate of 3 Gbit/s.
Lung Microbiome in Idiopathic Pulmonary Fibrosis and Other Interstitial Lung Diseases (2022)

Interstitial lung diseases represent a heterogeneous and wide group of diseases in which factors leading to disease initiation and progression are not fully understood. Recent evidence suggests that the lung microbiome might influence the pathogenesis and progression of interstitial lung diseases. In recent years, the utilization of culture-independent methodologies has allowed the identification of complex and dynamic communities of microbes, in patients with interstitial lung diseases. However, the potential mechanisms by which these changes may drive disease pathogenesis and progression are largely unknown. The aim of this review is to discuss the role of the altered lung microbiome in several interstitial lung diseases. Untangling the host-microbiome interaction in the lung and airway of interstitial lung disease patients is a research priority. Thus, lung dysbiosis is a potentially treatable trait across several interstitial lung diseases, and its proper characterization and treatment might be crucial to change the natural history of these diseases and improve outcomes.
High Deposition Welding for Shipbuilding (2012)

A new welding process has been developed which uses a hybrid concept. A portable induction coil is operated ahead of the arc welding torch, and heats the surfaces of the weld to near the melting point. Then the heat generated by the welding arc is primarily used only to melt the welding wire. The process operates at speeds of 2-3 times the speed of conventional arc welding and has the added advantage of substantially reducing weld distortion. The need for weld joint preparation, such as beveling, is eliminated for butt joints, even in fairly thick parts, which dramatically improves welding productivity.
High resolution spectroscopy using fiber laser frequency combs (2008)

The output of a femtosecond fiber laser can be both spectrally broadened and stabilized, thereby providing a broadband coherent source in the near infrared. In the frequency domain, the result is a frequency comb with frequency stabilities at the millihertz level (relative to the reference), while in the time domain, the result is an optical pulse train with sub-femtosecond relative timing jitter. This coherent source can be used for high-resolution measurements in a range of areas including frequency metrology, ranging, vibrometry, and spectroscopy. We will discuss the performance of these sources, focusing on recent work applying them to high-resolution spectroscopy.

Superconducting Conversion of the Oak Ridge Isochronous Cyclotron (1981)

The superconducting conversion of the Oak Ridge Isochronous Cyclotron (ORIC) will replace the existing aluminum main magnet coils with a NbTi superconducting coil system to provide an increase in magnetic field from 1.9 to 3.3 T. The higher magnetic field will provide a three-fold increase in maximum energy capability of the cyclotron for high mass ions. The conversion will include a new beam extraction system, magnet yoke stiffening to counteract the increased magnetic forces, and minor modifications to the beam transport systems and shielding.
Role of a Perivascular Ultrasonic Micro-flow Probe in Aneurysm Surgery (1998)

There are various intraoperative monitoring devices available today for helping the neurosurgeons the progress of the intracranial aneurysm surgery. Till now the intraoperative ultrasonic blood flow probes has been used only in vascular, cardiac, and transplant surgery. In the University of Illinois at Chicago we have been able to use the same technology in various neurovascular surgeries. We describe the use of the ultrasonic perivascular blood flow probes in patients operated for clipping of intracranial aneurysm. The use of this perivascular micro-flow probe and its importance in cerebral aneurysm will be discussed.
Der besondere Fall: Vaginaler Fremdkörper (Zange) als Zufallsbefund anläßlich der Primäroperation eines Mammakarzinomes (1995)

A 29 year-old patient was admitted for surgery because of two breast lumps. One of these was suspicious for malignancy by a mammogram and palpation. When her history was taken, the patient mentioned putrid vaginal discharge and denied any previous gynaecologic examination. After initial hesitancy, the patient agreed to have a pelvic examination. This revealed an oxydized iron rod protruding 2 cm out of the vagina. The object was identified by x-ray examination as one handle of iron forceps often used for cutting metal wires. The patient had been carrying this foreign body for fifteen years. She was not willing to relate any information about the cause of the manipulation or any eventual culprit. She was consistent and her personality was dominated by introverted behaviour. The foreign body was removed under the same anaesthesia as that used for the operation on the breast cancer.
High‐Performance Isotropic Thermo‐Electrochemical Cells Using Agar‐Gelled Ferricyanide/Ferrocyanide/Guanidinium (2023)

An isotropic thermo-electrochemical cell is introduced with a high Seebeck coefficient (<i>S</i> <sub>e</sub>) of 3.3 mV K<sup>-1</sup> that uses a ferricyanide/ferrocyanide/guanidinium-based agar-gelated electrolyte. A power density of about 20 µW cm<sup>-2</sup> is achieved at a temperature difference of about 10 K, regardless of whether the heat source is on the top or bottom section of the cell. This behavior is very different from that of cells with liquid electrolytes, which exhibit high anisotropy, and for which high <i>S</i> <sub>e</sub> values are achieved only by heating the bottom electrode. The guanidinium-containing gelatinized cell does not exhibit steady-state operation, but its performance recovers when disconnected from the external load, suggesting that the observed power drop under load conditions is not due to device degeneration. The large <i>S</i> <sub>e</sub> value and isotropic properties can mean that the novel system represents a major advancement from the standpoint of harvesting of low-temperature heat, such as body heat and solar thermal heat.
Polymerization in Microemulsions (1989)

Structural entities in water-in-oil (W/O) microemulsion at low water content are reviewed. These structures include monomers of surfactant associated with a few water and cosurfactant molecules. These small aggregates are stable in a non-polar environment in spite of their polar character and provide an interesting case of unusual interaction between polymers and microemulsion structures. Examples are provided of cases when this interaction is important for stability of microemulsions with added organic or inorganic polymers.
Adrenergic Antagonists Reduce Lactic Acidosis in Response to Hemorrhagic Shock (1999)

Epinephrine release in response to hypotension is a primary stimulus for muscle lactate production in this model of hemorrhagic shock. Hypoxia alone does not explain the increased lactate levels because tissue perfusion was not altered by the adrenergic antagonists. These observations challenge the rationale behind lactate clearance as an end point for resuscitation after hemorrhagic shock.
Development and characterization of adiabatic shear prone tungsten heavy alloys. Final report, 1 October 1991-31 January 1993 (1993)

Depleted uranium (DU) is currently the top-performing kinetic energy penetrator, followed closely (but not matched) by several tungsten heavy alloy variants. Because of the adverse environmental impact associated with DU, it is extremely desirable to determine a means of upgrading the ballistic performance of heavy alloys to a level at least comparable to that of DU. It is thought that the reason for the improved ballistic performance of DU-0.75 Ti alloy is embedded in its ability to self sharpen during armor penetration, and it is further postulated that this self-sharpening ability is due to the susceptibility of DU to adiabatic shear during penetration events. The contrasting inability of current tungsten heavy alloys to localize shear during penetration causes mushrooming at the head of the projectile, thus, decreasing the depth of penetration. Consequently, there is a great urgency to develop new tungsten alloys that will exhibit localized, unstable shear failure, and associated self sharpening during armor penetration.

Wireless-Capsule Diagnostic Endoscopy for Recurrent Small-Bowel Bleeding (2001)

The New Eng land Jour nal of Medicine pertrophy, and an aortic-valve area of less than 0.6 cm 2 or an aortic-valve index no higher than 0.6 cm 2 per square meter of body-surface area). 2 However, none of these echocardiographic findings have demonstrated the predictive power that Rosenhek et al. report for the degree of valvular calcification and the increase in aortic-jet velocity. Their results add to the existing evidence that an absence of symptoms is an insufficient reason to delay aortic-valve replacement in certain cases. The findings also shed light on the matter of which patients should be considered for early surgery.
Optimally scaling permutation routing on reconfigurable linear arrays with optical buses (2003)

We present an optimal and scalable permutation routing algorithm for three reconfigurable models based on linear arrays that allow pipelining of information through an optical bus. Specifically, for any P/spl les/N, our algorithm routes any permutation of N elements on a P-processor model optimally in O(N/P) steps. This algorithm extends naturally to one for routing h-relations optimally in O(h) steps. We also establish the equivalence of the three models, LARPBS, LPB, and POB. This implies an automatic translation of algorithms (without loss of speed or efficiency) among these models.
Acid−Amide Intermolecular Hydrogen Bonding (1997)

A 2,2-dimethylbutynoic acid with a pyridone terminus (1) acts as its self-complement in molecular recognition to form an intermolecularly hydrogen-bonded dimer with hydrogen bonding between the amide and carboxylic acid group. The dimer is found in crystals of 1 by X-ray diffraction, in chloroform solution by 1H-NMR experiments and vapor pressure osmometry, and in the gas phase by FAB-MS.
Mushrooms Ability to Deter Diabetes: A Review (2023)

For its potential as a supplement to conventional drugs and therapies, mushrooms have been the subject of substantial medical investigation. Many in vitro and in vivo studies using animal and human models have demonstrated that the polysaccharides, oligosaccharides, dietary fibres, peptides, amino acids, fatty acids, micronutrients, and phenolic bioactives present in mushrooms impart a wide range of medical and therapeutic approaches properties. These components, either individually or together, follow complex routes to display biological and functional activity. These higher classes of fungi have a range of medicinal properties, including antioxidant potential, anti-inflammatory action, and anti-aging, as a result of their high fibre and polysaccharide content. Several dietary fibres and saccharides have immunosuppression, anti-diabetic, anti-hypertensive, and anti-hyperlipidemic properties. Terpenoids and phenolic compounds in the mushroom are responsible for its protective benefits on the heart, liver, neurons, kidneys, and liver. Among other anti-diabetic mushrooms are Pleurotusostreatus, Ganodermalucidum, Grifolafrondosa, and Lentinusedodes. In addition to reducing cholesterol production and absorption, mushrooms also reduce food consumption, promoting a healthy gastrointestinal system, and promote healthier. We compiled the most recent research on the benefits of consuming edible mushrooms for your health in this article. So, it can be concluded that regularly including mushrooms in your diet may aid in the prevention of diabetes
Brazilian green propolis promotes TNFR2 expression on regulatory T cells (2021)

FoxP3<sup>+</sup> regulatory T cells (Tregs) are needed to suppress inflammatory diseases and maintain immune homeostasis. The suppressive function of Tregs can be used to control autoimmune or inflammatory diseases; therefore, it is well studied how Tregs can be artificially up- or downregulated in vitro and in vivo, by using antibodies, chemical compounds, foods, and natural resources. Propolis is a famous functional food that has an anti-inflammatory effect. However, the influences of propolis on Treg function have not been fully evaluated so far. Here, we demonstrated that Brazilian green propolis increases TNFR2 expression in Tregs via the IRF4/cMyc axis, and artepillin C was a major effective component of propolis on Tregs. These results indicate that propolis and artepillin C have the potential as Treg activators via TNFR2 expression and may be useful for the prevention and/or therapy of autoimmune or inflammatory diseases.

Increase in the Mobility of Photogenerated Positive Charge Carriers in Polythiophene (2005)

We report the increase in the mobility of charge carriers in regioregular poly 3-hexyl thiophene (RR-P3HT) films by mixing them with tetracyanoethylene (TCNE), which is examined by in situ time-resolved microwave conductivity (TRMC) and transient optical spectroscopy (TOS). TCNE acts not only as an electron acceptor which increases the number of charge carriers on photoexposure but also as a functional additive which enhances the mobility of the charge carriers. This conclusion was deduced from the results of fluorescence quenching, transient optical absorption and photobleaching, and comparison of the TRMC signal with the TOS signal. The combination of the TRMC and TOS techniques represents a comprehensive and fully experimental approach to the determination of the intrinsic carrier mobility in conjugated polymers.
Incidence and Nature of Adverse Events During Pediatric Sedation/Anesthesia for Procedures Outside the Operating Room: Report From the Pediatric Sedation Research Consortium (2006)

Our data indicate that pediatric sedation/anesthesia for procedures outside the operating room is unlikely to yield serious adverse outcomes in a collection of institutions with highly motivated and organized sedation services. However, the safety of this practice depends on the systems' ability to manage less serious events.
