The norepinephrine-to-epinephrine ratio in patients with a history of suicide attempts (1985)

Norepinephrine and epinephrine were measured serially in 24-hour urine collections from 99 male psychiatric inpatients with mixed diagnoses. The group was blindly divided into those with a previous history of at least one suicide attempt (N = 38) and those without such a history (N = 61). The ratio of norepinephrine-to-epinephrine levels was significantly lower in the group with a history of suicide attempts. The authors discuss the possibility that a low norepinephrine-to-epinephrine ratio is a risk factor for suicidal behavior.
Protective Effect of Tropical Highland Blackberry Juice (Rubus adenotrichos Schltdl.) Against UVB‐Mediated Damage in Human Epidermal Keratinocytes and in a Reconstituted Skin Equivalent Model (2013)

Solar ultraviolet (UV) radiation, particularly its UVB (280-320 nm) spectrum, is the primary environmental stimulus leading to skin carcinogenesis. Several botanical species with antioxidant properties have shown photochemopreventive effects against UVB damage. Costa Rica's tropical highland blackberry (Rubus adenotrichos) contains important levels of phenolic compounds, mainly ellagitannins and anthocyanins, with strong antioxidant properties. In this study, we examined the photochemopreventive effect of R. adenotrichos blackberry juice (BBJ) on UVB-mediated responses in human epidermal keratinocytes and in a three-dimensional (3D) reconstituted normal human skin equivalent (SE). Pretreatment (2 h) and posttreatment (24 h) of normal human epidermal keratinocytes (NHEKs) with BBJ reduced UVB (25 mJ cm(-2))-mediated (1) cyclobutane pyrimidine dimers (CPDs) and (2) 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) formation. Furthermore, treatment of NHEKs with BBJ increased UVB-mediated (1) poly(ADP-ribose) polymerase cleavage and (2) activation of caspases 3, 8 and 9. Thus, BBJ seems to alleviate UVB-induced effects by reducing DNA damage and increasing apoptosis of damaged cells. To establish the in vivo significance of these findings to human skin, immunohistochemistry studies were performed in a 3D SE model, where BBJ was also found to decrease CPDs formation. These data suggest that BBJ may be developed as an agent to ameliorate UV-induced skin damage.
Bosch Electronic Fuel Injection with Closed Loop Control (1975)

&lt;div class="htmlview paragraph"&gt;The paper describes an electronic fuel injection system with improved performance. This is achieved by basic system considerations as well as by sophisticated electronics design making use of custom designed bipolar integrated circuits. By using an oxygen sensor, it is possible to detect the stoichiometric mixture and to use a closed loop control to meet the proposed United States Federal Emission Standards of 1978. The basic electronic design, the closed loop control, and the oxygen sensor are described.&lt;/div&gt;
Power-Controlled Job Slowdown in Data Centers (2022)

As compute demands soar upwards, it is essential that systems not only scale throughput and latency, but also improve energy efficiency and alleviate power bottlenecks. A common quality of service metric for user-facing data center services is slowdown, the ratio of the actual response time of a computational job to the expected response time under no delay. In this work, we expand the definition of slowdown to the power-controlled, rate-optimizing setting. We take the initial steps to investigate and analyze the key tradeoffs between power and slowdown costs. Formulating the problem in a dynamic programming framework, we provide analytic solutions in the single class job setting, and formulate the multi-class job setting. Numerical solutions to the dynamic programming equation are also produced, and confirm the analytical results and parameter tradeoffs. In particular, we demonstrate both analytically and numerically that reasonable tradeoffs can be made between power and slowdown by optimizing the server processing rate. Optimizing for power consumption is increasingly important as data centers’ tackle the transition to renewable energy sources.
[Histologic tissue processing in an automated microwave histoprocessor]. (1999)

A new vacuum histoprocessor has been tested as well as new more effective protocols to work with this processor. The device allows histoprocessing of 50 samples simultaneously of surgery, biopsy or autopsy material during 1-1.5 h. Apart from the standard protocols, new protocols with a much lower (5-10 times) expenditure of the chemicals can be implemented due to combination of microwaves and vacuum. Each protocol was tested repeatedly (20 and more times) with stable good quality of microscopic image.
A new algorithm for detecting corners in digital images (2002)

Corners and vertices are important features in images, which are frequently used for scene analysis, stereo matching and object tracking. Many algorithms for detecting the corners have been reported up to now. In this paper, a new algorithm is presented. The algorithm is based on measuring the variance of the directions of the gradient of brightness. The probability of the event that a point belongs to the approximation of a straight segment of the isoline of brightness passing through the point being tested is computed using the technique of Bayesian estimations and used as a weight. The algorithm is presented both from the theoretical and from the practical point of view. The results of tests show that the algorithm is better than other known algorithms that are usually used for solving the problem.
Stabile, Thermoresponsive Colloidal Clusters: An Unusual Morphology of Polymer Dispersions (2013)

A new class of colloidal polymeric particles consisting of polystyrene spheres grown in a poly( N ‐isopropyl acrylamide) precursor scaffold is synthesized via redox‐initiated heterophase polymerization. The morphology and thermoresponsiveness of these assemblies is proven by electron microscopy investigations and temperature‐dependent measurements of the change of both the speed of sound travelling through the dispersion and the hydrodynamic particle size. Electron microscopy (EM) micrographs (transmission and scanning EM as well cryo‐scanning EM) prove the existence of colloidal clusters when the freeze‐dried copolymer is redispersed in pure water. The clusters have a size of several micrometers, contain about 800 polystyrene particles with diameter below 100 nm, and show a highly reproducible thermoresponsive behavior with a lower critical solution temperature corresponding to that of pure poly( N ‐isopropyl acrylamide). image
Computational Fourier Optics: A MATLAB Tutorial (2011)

Analytic Fourier Theory Review 1.1 A Little History and PurposeThe branch of optical science known today as "Fourier optics" had its genesis in the 1940s through the 1960s with the application of new telecommunications and circuit design analysis techniques in optical diffraction theory. 1 In 1968 this upstart discipline was given a permanent foothold with the publication of Introduction to Fourier Optics, by Joseph W. Goodman, a seminal textbook that explained and united the fundamental concepts, and which continues to add significantly to the application of Fourier optics in subsequent editions. 2Fourier optics is now the cornerstone for the analysis of diffraction, coherence, and imaging, as well as specialized topics such as wavefront control, propagation through random media, and holography.The study of Fourier optics today leads naturally toward the computer for at least two reasons: (1) diffraction integral expressions are difficult to solve analytically for all but a few of the simplest aperture functions, and (2) the fast Fourier transform (FFT) algorithm combined with the linear systems framework of Fourier optics provides an extremely efficient computational approach for solving wave optics problems.Certainly, the computer can be applied directly in finding exceedingly accurate solutions to diffraction problems using numerical integration techniques. 3However, this book is really about the FFT and how to apply it to a variety of Fourier optics problems.The computer coding steps mirror the analytic concepts and the FFT's speed makes it possible to perform thousands of optical propagation or imaging simulations in a reasonable amount of time.In fact, the methods explored in this book form the basis for wave (or physical) optics simulation tools that are widely used in industry.But, of course, there's no free lunch (…if there were, perhaps we could be eating while studying Fourier optics...).It turns out the FFT is an accomplice to various numerical artifacts.We do our best in this book to expose these issues and provide constraints to help minimize the damage.This is also a tutorial text with step-by-step instructions, not only for coding Fourier optics problems, but also for MATLAB, our software application of choice.So, if you are new to MATLAB, don't worry!Chapter 3 starts at the
A sex‐specific, COX‐derived/thromboxane receptor activator causes depolarization and vasoconstriction in male mice mesenteric resistance arteries (2020)

We investigated whether sex differences exist in cyclooxygenase-dependent effects on membrane potential and relaxation in mice mesenteric resistance arteries. Mesenteric small arteries of 9- to 12-week-old, male and female, wild-type mice, db/+ mice and diabetic db/db mice were mounted in myographs for measurements of isobaric diameter and smooth muscle cell membrane potential. Acetylcholine caused smaller dilation of arteries from male db/+ mice compared to arteries from female db/+ mice. In the presence of the NO synthase inhibitor N<sup>ω</sup> -nitro-L-arginine methyl ester (L-NAME), acetylcholine-induced dilation of arteries from males increased in the presence of indomethacin and the COX-1-specific inhibitor FR122047. The presence of indomethacin was also associated with a more negative membrane potential in arteries from males. In arteries from db/db mice, no sex differences were seen. In arteries from male but not female wild-type mice, the thromboxane receptor blocker SQ29,548 increased relaxation to acetylcholine. In contrast to arteries from female mice, COX (most likely COX-1)-derived prostanoids and activation of thromboxane receptors counteract acetylcholine vasodilatation probably through increased smooth muscle depolarization in arteries from male mice. In mice with diabetes and pronounced endothelial dysfunction, inhibition of COX did not enhance acetylcholine vasodilatation.
Effect of Si and Fe on the Recrystallization Response of Al-Mn Alloys with Zr Addition (2012)

AlMn alloys are often used for the production of automotive heat exchanger ns. During brazing at about 600 C, recrystallization and grain coarsening resulting in the reduction of the strength and possible buckling of the n can occur. In order to obtain a good recrystallization resistance, the alloy should contain a dense and homogeneous distribution of second phase particles. The eect of Si and Fe addition on the recrystallization response of AlMnZr alloys direct-chill cast in the laboratory conditions and twin-roll cast in the industrial conditions was examined. Microstructure of the alloys was characterized during downstream processing. The particles were analyzed by light metallography, energy dispersive X-ray spectroscopy and by means of electron backscattering diraction. Computer assisted quantitative particle analysis was carried out on eld emission gunscanning electron microscope micrographs. Vickers hardness and electrical conductivity were measured at thicker sheets, while at the nal gauge of 65 m the 0.2% proof stress was evaluated. The best recrystallization resistance had twin-roll cast alloy containing 0.5 wt% Si and 0.2 wt% Fe.

Mean field analysis of the magnetic properties of amorphous transition-metal–rare-earth alloys (1978)

A generalized form of mean field theory and procedures for applying it to analyze experimental data on the temperature dependence of the saturation magnetization or the effective gyromagnetic factor of n-component amorphous transition-metal–rare-earth alloys are outlined. This analysis yields the spin values of each component and the effective exchange interaction energies between them, from which other magnetic properties such as the subnetwork magnetizations and the macroscopic exchange stiffness can be calculated. Examples of application of this mean field procedure are given.
Feasibility and Safety of Single-Probe Cryoablation with Liquid Nitrogen: An Initial Experience in 24 Various Tumor Lesions (2022)

Security Attributes Based Digital Rights Management (2002)

ost real-life systems delegate responsibilities to di�erent authorities. We apply this model to a dig- ital rights management system, to achieve exible security. In our model a hierarchy of authorities issues certi�cates that are linked by cryptographic means. This linkage establishes a chain of control, identity-attribute-rights, and allows exible rights control over content. Typical security objectives, such as identi�cation, authentication, authoriza- tion and access control can be realised. Content keys are personalised to detect illegal super distri- bution. We describe a working prototype, which we develop using standard techniques, such as stan- dard certi�cates, XML and Java. We present ex- perimental results to evaluate the scalability of the system. A formal analysis demonstrates that our design is able to detect a form of illegal super dis- tribution.
Fast timing-driven partitioning-based placement for island style FPGAs (2003)

In this paper we propose a partitioning-based placement algorithm for FPGAs. The method incorporates simple, but effective heuristics that target delay minimization. The placement engine incorporates delay estimations obtained from previously placed and routed circuits using VPR [6]. As a result, the delay predictions during placement more accurately resemble those observed after detailed routing, which in turn leads to better delay optimization. An efficient terminal alignment heuristic for delay minimization is employed to further optimize the delay of the circuit in the routing phase. Simulation results show that the proposed technique can achieve comparable circuit delays (after routing) to those obtained with VPR while achieving a 7-fold speedup in placement runtime.
Endoluminal sealing of vascular wall disruptions with radiofrequency‐heated balloon angioplasty (1993)

Suboptimal luminal widening or acute closure secondary to arterial dissection remain significant risks of percutaneous transluminal balloon angioplasty. Non surgical techniques are often employed in an attempt to repair dissections either as temporary or definitive treatment. The aim of this study was to test the hypothesis that radiofrequency thermal balloon angioplasty at an operating temperature of 70 degrees C and low inflation pressure could seal dissections and perforations in a model of severe arterial wall damage. Dissections and perforations were created in renal (n = 4) and carotid (n = 4) arteries in four mongrel dogs. Endoluminal sealing was then attempted with conventional balloon angioplasty or radiofrequency thermal balloon angioplasty (2 atm at 70 degrees C). Contrast dye extravasation persisted in all cases following conventional balloon angioplasty but completely resolved with radiofrequency balloon angioplasty in all but one artery. Histologic examination of the arteries treated with radiofrequency balloon angioplasty showed extensive thermal injury, including transmural coagulation necrosis, flattening of the internal elastic lamina, and medial thinning. On the basis of these results, the utility of thermal balloon angioplasty for endoluminal sealing of dissections and perforations complicating angioplasty deserves further evaluation.
A context-tree weighting method for text generating sources (1997)

Summary form only given. The authors discuss context tree weighting (Willems et al. 1995). This was originally introduced as a sequential universal source coding method for the class of binary tree sources. The paper discusses the application of the method to the compaction of ASCII sequences. The estimation of redundancy and model redundancy are also considered.
Linearity measurements of Si/SiGe Heterojunction Bipolar Transistor using a Large Signal Network Analyzer with an harmonic Load-Pull setup (2006)

This paper presents original multi-harmonic modulated load-pull measurements on a Si/SiGe HBT of STMicroelectronics technology. The original aspect is that the linearity, power and efficiency measurements are realized on an active load-pull test-bench associated with a large signal network analyzer. The aim of the measurements is to optimize and characterize the HBT excited by a CW and a two-tone signal. The comparison with the simulation lets to validate the models in large-signal
Electron microscopy changes of cochlear implant electrodes with permanently high impedances (2011)

Persistently high impedances were related to changes on the electrodes' surface and to coating with tissue in this case. These changes can result in adhesive processes and technical malfunction, leading to explantation and difficult re-implantation. Therefore, close and professional supervision of cochlear implant patients is needed.

Electron Heating by Ion Acoustic Turbulence in Plasmas (1979)

Anomalous resistivity caused by ion acoustic turbulence is observed in a current-carrying discharge-tube plasma. Above 0.05 V/cm, which is nearly equal to a critical field predicted from an electron collision frequency, the resistivity increases in proportion to the electric field. When a magnetic field is applied to the plasma in the presence of the ion acoustic turbulence, the electron temperature rises. It is found that the electron heating is brought about by the turbulent heating.
Wish Branches: Combining Conditional Branching and Predication for Adaptive Predicated Execution (2006)

Predicated execution has been used to reduce the number of branch mispredictions by eliminating hard-to-predict branches. However, the additional instruction overhead and additional data dependencies due to predicated execution sometimes offset the performance advantage of having fewer mispredictions. We propose a mechanism in which the compiler generates code that can be executed either as predicated code or non-predicated code (i.e., code with normal conditional branches). The hardware decides whether the predicated code or the non-predicated code is executed based on a run-time confidence estimation of the branch's prediction. The code generated by the compiler is the same as predicated code, except the predicated conditional branches are NOT removed - they are left intact in the program code. These conditional branches are called wish branches. The goal of wish branches is to use predicated execution for hard-to-predict dynamic branches and branch prediction for easy-to-predict dynamic branches, thereby obtaining the best of both worlds. We also introduce a class of wish branches, called wish loops, which utilize predication to reduce the misprediction penalty for hard-to-predict backward (loop) branches. We describe the semantics, types, and operation of wish branches along with the software and hardware support required to generate and utilize them. Our results show that wish branches decrease the average execution time of a subset of SPEC INT 2000 benchmarks by 14.2% compared to traditional conditional branches and by 13.3% compared to the best-performing predicated code binary.

The scientific basis for a satellite mission to retrieve CCN concentrations and their impacts on convective clouds (2012)

Abstract. The cloud -mediated radiative forcing is widely recognized as the main source of uncertainty in our knowledge of the anthropogenic climate forcing and in our understanding of climate sensitivity. Current outstanding challenges are (1) global measurements of cloud condensation nuclei (CCN) in the cloudy boundary layer from space, and, (2) disentangling the effects of aerosols from the thermodynamic and meteorological effects on the clouds. Here we present a new concept for a way to overcome these two challenges, using relatively simple passive satellite measurements in the visible and IR. The idea is to use the clouds themselves as natural CCN chambers by retrieving simultaneously the number of activated aerosols at cloud base, Na, and the cloud base updraft speed. The Na is obtained by analyzing the distribution of cloud drop effective radius in convective elements as a function distance above cloud base. The cloud base updraft velocities are estimated by double stereoscopic viewing and tracking of the evolution of cloud surface features just above cloud base. In order to resolve the vertical dimension of the clouds, the field of view will be 100 m for the microphysical retrievals, and 50 m for the stereoscopic measurements. The viewing geometry will be 30 degrees off nadir eastward, with the Sun in the back at 30 degrees off zenith westward, which requires a Sun synchronous orbit at 14:00 LST. Having measured simultaneously the thermodynamic environment, the vertical motions of the clouds, their microstructure and the CCN concentration will allow separating the dynamic from the CCN effects. This concept is being applied in the proposed satellite mission named Clouds, Hazards and Aerosols Survey for Earth Researchers (CHASER).
