GPU PRICES AND CRYPTOCURRENCY RETURNS (2022)

We look at the association between the price of a cryptocurrency and the secondary market prices of the hardware used to mine it. We find the prices of the most efficient Graphical Processing Units (GPUs) for Ethereum mining are significantly positively correlated with the daily price returns to that cryptocurrency.
CvT: Introducing Convolutions to Vision Transformers (2021)

We present in this paper a new architecture, named Convolutional vision Transformer (CvT), that improves Vision Transformer (ViT) in performance and efficiency by introducing convolutions into ViT to yield the best of both designs. This is accomplished through two primary modifications: a hierarchy of Transformers containing a new convolutional token embedding, and a convolutional Transformer block leveraging a convolutional projection. These changes introduce desirable properties of convolutional neural networks (CNNs) to the ViT architecture (\ie shift, scale, and distortion invariance) while maintaining the merits of Transformers (\ie dynamic attention, global context, and better generalization). We validate CvT by conducting extensive experiments, showing that this approach achieves state-of-the-art performance over other Vision Transformers and ResNets on ImageNet-1k, with fewer parameters and lower FLOPs. In addition, performance gains are maintained when pretrained on larger datasets (\eg ImageNet-22k) and fine-tuned to downstream tasks. Pre-trained on ImageNet-22k, our CvT-W24 obtains a top-1 accuracy of 87.7\% on the ImageNet-1k val set. Finally, our results show that the positional encoding, a crucial component in existing Vision Transformers, can be safely removed in our model, simplifying the design for higher resolution vision tasks. Code will be released at \url{https://github.com/leoxiaobin/CvT}.

[Measuring electric impedance of organs--methodologic principles]. (1991)

Ischemia causes changes in organ tissue (e.g. during operation or transplantation) which may finally lead to irreversible injury, so that the organ can no longer be resuscitated. To the extent that these changes affect the electrical properties of the tissue they are manifested in the impedance spectrum. As an example, the course of impedance of a HTK-protected porcine liver is presented in the frequency range of 0.1 Hz to 10 MHz, which includes two dispersion--alpha- and beta-dispersion. Using a suitable electrical equivalent circuit analogue to the structure of the liver, the behavior of the alpha- and beta-dispersion is explained on the basis of gap junction closure and narrowing of the extracellular space due to cell swelling.
Reproducibility of Optic Disk Topographic Measurements with the Topcon ImageNet and the Heidelberg Retina Tomograph (1998)

Both systems provided reproducible data. The optic disk parameters provided by the Heidelberg Retina Tomograph had a better reproducibility than those obtained from the Topcon ImageNet.
Fabrication methods of optical resonant filters with a close-to-rectangle filtering profile (2004)

The potential applications of optical resonant filters for optical communication systems can be significant. Three approaches to achieve a close-to-rectangle filtering profile for optical resonant filter were investigated and proven experimentally. The combination of the filtering sharpness, which comes from the resonance nature, and a flattened filtering window realized the close-to-rectangle filtering profile that can enhance the bandwidth efficiency.
Improved queueing analysis of shared buffer switching networks (2002)

Several methods for analyzing the queuing behavior of switching networks with flow control and shared buffer switches are described. The methods are compared on the basis of accuracy and computation speed, with the performance metric of most concern being the maximum throughput. The best of the methods accurately predicts throughput for multistage networks constructed from large switches (>or=8 ports).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Kar3-Interacting Protein Cik1p Plays a Critical Role in Passage Through Meiosis I in <i>Saccharomyces cerevisiae</i> (2001)

Meiosis I in Saccharomyces cerevisiae is dependent upon the motor protein Kar3. Absence of Kar3p in meiosis results in an arrest in prophase I. Cik1p and Vik1p are kinesin-associated proteins known to modulate the function of Kar3p in the microtubule-dependent processes of karyogamy and mitosis. Experiments were performed to determine whether Cik1p and Vik1p are also important for the function of Kar3p during meiosis. The meiotic phenotypes of a cik1 mutant were found to be similar to those of kar3 mutants. Cells without Cik1p exhibit a meiotic defect in homologous recombination and synaptonemal complex formation. Most cik1 mutant cells, like kar3 mutants, arrest in meiotic prophase; however, in cik1 mutants this arrest is less severe. These data are consistent with the model that Cik1p is necessary for some, but not all, of the roles of Kar3p in meiosis I. vik1 mutants sporulate at wild-type levels, but have reduced spore viability. This loss in viability is partially attributable to vegetative chromosome loss in vik1 diploids. Cellular localization experiments reveal that Kar3p, Cik1p, and Vik1p are present throughout meiosis and are consistent with Cik1p and Vik1p having different meiotic roles.
The side‐effects of plant extracts and metabolites of <i>Reynoutria sachalinensis</i> (F. Schmidt) Nakai and conventional fungicides on the beneficial organism <i>Trichogramma cacoeciae</i> Marchal (Hym., Trichogrammatidae) (1999)

The aim of this study was to investigate the side‐effects of plant extracts (plant strengthener with resistance inducing properties) and conventional fungicides on the egg parasitoid Trichogramma cacoeciae Marchal. Two plant extracts and one metabolite from Reynoutria sachalinensis (F. Schmidt) Nakai (crude water extract (Rey‐crude & reg;), which is used for the control of powdery mildew and other diseases, a methanolic fraction of this extract (Rey‐meth & reg;) and the anthraquinone plant constituent (Physcion & reg;), as well as four fungicides (Thiram & reg;, Dithane & reg; M45, Euparen M & reg; and Kumulus & reg;) were tested. Adults of T. cacoeciae of uniform age were exposed to fresh dry film of the compounds and the percentage reduction in parasitism compared with water‐treated controls was calculated. The results of experiments using the highest recommended concentrations sprayed on glass plates showed that the preparations greatly differed in their effect on the parasitoid. All of the conventional fungicides tested were found to be harmful. In contrast, Rey‐crude and Physcion were harmless to T. cacoeciae , whereas the fraction Rey‐meth was slightly harmful. In further experiments the side‐effects of the plant protection agents on T. cacoeciae were compared when sprayed at different concentrations either on glass plates or on vine leaves. The results confirmed the findings of the first trials but showed that side‐effects of the compounds Dithane M45 and Euparen M were less toxic when applied to vine leaves.
An automatic trace analysis tool generator for Estelle specifications (1995)

This paper describes the development of Tango, an automatic generator of backtracking trace analysis tools for single-process specifications written in the formal description language, Estelle. A tool generated by Tango automatically checks the validity of any execution trace against the given specification, and supports a number of checking options. The approach taken was to modify an Estelle-to-C++ compiler. Discussion about nondeterministic specifications, multiple observation points, and on-line trace analysis follow. Trace analyzers for the protocols LAPD and TP0 have been tested and performance results are evaluated. Issues in the analysis of partial traces are also discussed.
SimPoint 3.0: Faster and More Flexible Program Phase Analysis (2005)

This paper describes the new features available in the SimPoint 3.0 release. The release provides two techniques for drastically reducing the run-time of SimPoint: faster searching to find the best clustering, and efficiently clustering large numbers of intervals. SimPoint 3.0 also provides an option to output only the simulation points that represent the majority of execution, which can reduce simulation time without much increase in error. Finally, this release provides support for correctly clustering variable length intervals, taking into consideration the weight of each interval during clustering. This paper describes SimPoint 3.0’s new features, how to use them, and points out some common pitfalls.
Trunk development of young trees (1973)

Trees were produced in these tests that could stand erect without staking—by eliminating stakes during production, by leaving lateral branches on the trunk, and by spacing plants so their tops were free to move. Even though rigidly staked trees with lower limbs removed grew taller, they developed less trunk caliper, regardless of whether they were lightly or severely pruned. These trees were not able to stand upright when planted out, while the unstaked trees needed little or no support.
Surgery and irradiation in the treatment of squamous cell cancer of the supraglottic larynx (1973)

Abstract Two hundred thirty-four patients with squamous cancer of the supraglottic larynx completed treatment for palliation or cure. Fifty-six per cent of the group were categorized as having stage III or IV disease by the American Joint Committee classification, whereas only 6 per cent were classified as having stage I lesions. Treatment policies were not rigid, but evolved during the period of time represented. Regional control of the lesion was adequate in patients with stage I disease treated with radiation therapy, and the disease was equally well controlled with either surgical or radiation methods in patients with stage II disease. Control of stage III and stage IV cancer was much improved by using both modalities of treatment. The absolute five year survival for patients having stage III and stage IV disease is 37 per cent, but 66 per cent of these patients will remain free of cancer above the clavicle. A rigid adherence to combined therapy in patients with stage III and stage IV disease may improve survival.
Aqueous Synthesis of Color-Tunable CuInS<sub>2</sub>/ZnS Nanocrystals for the Detection of Human Interleukin 6 (2013)

In this Article, we present a facile microwave-assisted synthesis route for the preparation of water-soluble and high-quality CuInS2/ZnS nanocrystals (NCs) with glutathione as the stabilizer. The as-prepared CuInS2/ZnS NCs exhibited small particle sizes (~3.3 nm), long photoluminescence lifetimes, and color-tunable properties ranging from the visible to the near-infrared by varying the initial ratio of Cu/In in the precursors. The low-toxicity, highly luminescent and biocompatible CuInS2/ZnS NCs were applied to cell imaging, showing that they could be used as promising fluorescent probes. Furthermore, the CuInS2/ZnS NCs were used as the signal labels for a fluoroimmunoassay of the biomarker IL-6, showing their great potential for use as reliable point-of-care diagnostics for biomarkers of cancer and other diseases.
An audio stream redirector for the Ethernet Speaker (2004)

The authors have developed the “Ethernet Speaker” (ES), a network‐enabled single board computer embedded into a conventional audio speaker. Audio streams are transmitted in the local area network using multicast packets, and the ES can select any one of them and play it back. A key requirement for the ES is that it must be capable of playing any type of audio stream, independent of the streaming protocol, or the encoding used. The authors achieved this by providing a streaming audio server built using the kernel‐based audio stream redirector (ASR) in the OpenBSD kernel. The ASR accepts input from any of the existing audio file players, or streaming audio clients. Since all audio applications have to be able to use the system audio driver, this system can accommodate any protocol or file format, provided that there exists some compatible player running under OpenBSD. This paper discusses the design and implementation of the server as an ASR, the streaming protocol developed for this application, and the implementation of the client.
Optofluidic analysis system for amplification-free, direct detection of Ebola infection (2015)

The massive outbreak of highly lethal Ebola hemorrhagic fever in West Africa illustrates the urgent need for diagnostic instruments that can identify and quantify infections rapidly, accurately, and with low complexity. Here, we report on-chip sample preparation, amplification-free detection and quantification of Ebola virus on clinical samples using hybrid optofluidic integration. Sample preparation and target preconcentration are implemented on a PDMS-based microfluidic chip (automaton), followed by single nucleic acid fluorescence detection in liquid-core optical waveguides on a silicon chip in under ten minutes. We demonstrate excellent specificity, a limit of detection of 0.2 pfu/mL and a dynamic range of thirteen orders of magnitude, far outperforming other amplification-free methods. This chip-scale approach and reduced complexity compared to gold standard RT-PCR methods is ideal for portable instruments that can provide immediate diagnosis and continued monitoring of infectious diseases at the point-of-care.

On determining the nature and orientation of magnetic directional discontinuities: Problems with the minimum variance method (2004)

The minimum variance method (MVA) has been used for over 3 decades to analyze directional discontinuities in solar wind magnetic field data. We recount how MVA was formulated and show that it does not do what many expect. We demonstrate a robust alternative for distinguishing tangential discontinuities from rotational discontinuities (RDs). We also stress that averaging magnetic field data to time resolutions of a minute or more (common with National Space Science Data Center data sets) obliterates RDs.
Implementation of a High-speed Sinusoidal Encoder Interpolation System (2004)

In order to meet higher performance demands on brushless motor controllers, motor feedback signals must meet correspondingly higher standards. Brushless motor controllers require angular feedback for motor commutation, and generally for one or more of the following: torque, velocity or position regulation. These feedback categories impose different requirements on the control system. In many brushless motor applications, sinusoidal encoders have significant advantages over square-wave encoders. Signal processing techniques for sinusoidal encoder feedback signals are considered in the context of a brushless motor positioning system. In particular, a method is presented for correcting gain and offset measurement errors based on ellipse-fitting techniques.

Chain-Breaking Antioxidants and Ferriheme-Bound Drugs are Synergistic Inhibitors of Erythrocyte Membrane Peroxidation (1998)

Induced erythrocyte membrane peroxidation (Em) is considered as an accurate model of reperfusion injuries and as such was used to investigate protective effects of various drugs. EMP was induced by an azo initiator and monitored by oxygen uptake. Both hydrophilic (ascorbic acid) and lipophilic (α-tocopherol, probucol, nicanartine) chain-breaking antioxidants as well as ferriheme-bound drugs (deferoxamine, chloroquine) inhibited EMP. When antioxidants and ferriheme-bound drugs were combined, synergistic effects were observed. It is proposed that ferriheme compounds which catalyse peroxide induced lipid peroxidation were blocked by deferoxamine and/or chloroquine. So these drugs inhibited at least partly the membrane peroxidation process and added their effects to the ones of chain-breaking antioxidants.
The Central Action of Procaine (1948)

Procaine was introduced as a local anesthetic with advantage over cocaine, especially as regards relative freedom from dangerous central effects. It [now] appears that when procaine hydrochloride is injected intravenously, the indications of a central effect are more emphatic when the solution is given rather rapidly. Probably some of the central effects of procaine can be obtained with local infiltration. This is, of course, generally admitted when untoward results occur, but it should also be considered in connection with the favorable effects. Macpherson recently expressed the idea that in some cases we are getting the beneficial effects of procaine injection through central action even though the injection is purposely given at or near the site of the pain.
KGR-1 thick adherend specimen evaluation for the determination of adhesive mechanical properties (1991)

The KGR-1 measuring device and the corresponding thick adherend specimen design used to determine adhesive shear properties are examined using a test program and finite element analysis. While affirming the overall value of this approach, it is found that the specimen geometry and materials will give nonuniform shear stress distributions for some adhesive thicknesses and stiffnesses. This nonuniformity introduces inaccuracies in the calculations of adhesive properties. Further inaccuracies may be introduced by using a dummy specimen without adhesive to correct for the adherend deformation. Finally, motion of the measuring pins relative to the adherend during testing may also lead to erroneous results. The objective of this paper is to improve user value of the KGR-1 procedure by providing recommendations for minimizing the sources of inaccuracies
