The use of portable ultrasound machine to assess a shelter's environment using venous thromboembolism screening (2013)

The eastern part of Japan experienced a magnitude 9.0 earthquake followed by a tsunami on the afternoon of March 11, 2011. A significant number of people were displaced from their homes and began living in temporary shelters. These shelters were located in schools, gymnasiums and 1 community centers, some of which were damaged and had inadequate facilities for the number of people they housed. I Subsequently, many shelters were overcrowded and lacked electricity. Much attention has been focused on the incidence of venous thromboembolism (VTE) after disasters since 2004, when the Mid-Niigata Prefecture Earthquake occurred. Some screening activities were undertaken to prevent the progression of VTE. Portable ultrasound machines play a primary role in screening, enabling efficient screening of at-risk populations who may otherwise have unreliable or no access to medical care. The use of ultrasound machines running on battery power allows for screening in areas without electricity. Monitoring the incidence of deep vein thrombosis and other biological data would enable local government authorities and medical staff to effectively manage shelters and temporary housing.
Relationships Between Sleep and Immune Function (1999)

Almost everyone is aware of the almost irresistible desire to sleep that occurs at the onset of “the flu.” Indeed, most loving parents or grandparents recommend sleep as a preventive measure and as an aid for recuperation from infection. Hippocrates dispensed similar advice; nevertheless, the investigation of relation­ ships between sleep and host defense systems had to wait 2100 years before being addressed scientifically. Within the past 10 years sleep responses to microbial challenge have been characterized as one component of the acute-phase response. These microbial-induced sleep responses may, in fact, contribute to host defense though this issue has yet to be satisfactorily resolved. Conversely, sleep loss is associated with changes in a variety of immune parameters and prolonged sleep loss with septicemia. The excess sleep associated with infectious challenge results from the amplification of physiological sleep mechanisms. Physiological sleep mechanisms include molecules that have traditionally been thought of as immune response modifiers but are now known to be constituitively expressed in brain and involved in several physiological regulations including sleep. This review will focus on some of the data that form the basis for these statements; it ends with aJAMES M. KRUEGER and JIDONG FANGshort discussion of the theoretical implications these data have on sleep, function and brain organization as it applies to sleep.
Efficacy of bilateral pallidotomy (1997)

Unilateral pallidotomy is a safe and effective treatment for medically refractory bradykinetic Parkinson's disease, especially in those patients with levodopa-induced dyskinesia and severe on-off fluctuations. The efficacy of bilateral pallidotomy is less certain. The authors completed 11 of 12 attempted bilateral pallidotomies among 150 patients undergoing pallidotomy at New York University. In all but one patient, the pallidotomies were separated by at least 9 months. Patients were selected for bilateral pallidotomy if they exhibited bilateral rigidity, bradykinesia, or levodopa-induced dyskinesia prior to treatment or if they exhibited disease progression contralateral to their previously treated side. The Unified Parkinson's Disease Rating Scale (UPDRS) and timed upper-extremity tasks of the Core Assessment Protocol for Intracerebral Transplantation (CAPIT) were administered to all 12 patients in the “off” state (12 hours without receiving medications) preoperatively and again at 6 and 12 months after each procedure. The median UPDRS and contralateral CAPIT scores improved 60% following the initial procedure (p = 0.008, Wilcoxon rank sums test). The second pallidotomy generated only an additional 10% improvement in the UPDRS and CAPIT scores ipsilateral to the original procedure (p = 0.05). Worsened speech was observed in two cases. In the 12th case, total speech arrest was noted during test stimulation. Speech returned within minutes after stimulation was halted. Lesioning was not performed. These results indicate that bilateral pallidotomy has a narrow therapeutic window. Motor improvement ipsilateral to the first lesion leaves little room for further improvement from the second lesion and the risk of speech deficit is greatly enhanced. Chronic pallidal stimulation contralateral to a previously successful pallidotomy may prove to be a safer alternative for the subset of patients who require bilateral procedures.
Generating precision nonlinear FM chirp waveforms (2007)

It is well-known that Non-Linear FM (NLFM) chirp modulation can advantageously shape the transmitted signal's Power Spectral Density such that the autocorrelation function (i.e. matched filter output) exhibits substantially reduced sidelobes from its Linear FM (LFM) counterpart. Consequently, no additional filtering is required and maximum Signal-to-Noise Ratio (SNR) performance is preserved. This yields a 1-2 dB advantage in SNR over the output of a LFM waveform with equivalent sidelobe filtering. However precision NLFM chirps are more difficult to design, produce, and process. This paper presents design and implementation techniques for Nonlinear FM waveforms. A simple iterative design procedure is presented that yields a NLFM phase/frequency function with the desired inherent sidelobe response. We propose to then generate the NLFM waveform by using a cascaded integrator/accumulator structure. Several specific architectures are examined to meet target performance criteria, including bandwidth constraints and sidelobe reduction goals. We first examine a fixed parameter set to generate a fixed polynomial phase function. Polynomial coefficients are selected to be constant during the pulse. Alternatively, a NLFM waveform can be generated via integrating a stepped parameter set, whereby parameters are constant over specific intervals, with the pulse width encompassing multiple intervals. The parameter changes in steps during the course of the pulse as a function of time. Alternatively yet, the parameter steps can be made a function of the pulse's instantaneous frequency.
Maximum-likelihood algorithm for quantum tomography (1999)

Optical homodyne tomography is discussed in the context of classical image processing. Analogies between these two fields are traced and used to formulate an iterative numerical algorithm for reconstructing the Wigner function from homodyne statistics.

Synthesis and Characterization of Gold Nanoparticles with Plasmon Absorbance Wavelength Tunable from Visible to Near Infrared Region (2012)

Gold nanorods with localized surface plasmon resonance (LSPR) can be chemically synthesized. We systematically investigated the effects of reaction parameters and centrifugation on the fine tuning of the rod dimension in scale-up production (80–100 mL). Nanorods of absorption bands from 600–1050 nm were fabricated with precise control of the aspect ratio (AR) from 1.5 to 8.9. Although all chemicals are important in directing the nanostructure, silver ion concentration and seed/Au 3+ ratio were the most effective variations to adjust the absorption wavelength. With a single surfactant under the influence of silver nitrate, short nanorods up to AR of 5 were synthesized with corresponding maximum absorption wavelength at 902 nm. To achieve higher aspect ratio with absorption band beyond 1,000 nm, two-surfactant growth solution was sought to further elongate the rod length. Centrifugation speed and times were found to exert significant influences on the final rod dimension, which is important during the purification process. In a relatively large quantity nanorod synthesis, even distribution and sufficient mixing of chemical ingredients play an essential role in determining the yield, uniformity, and stability of the final nanorod formation.
Initiation of roll waves (1961)

Abstract The theory proposed by Jeffreys to explain roll‐wave transition on a liquid surface is applied to the concurrent flow of a gas and liquid. Data are presented for the concurrent flow of air with water‐glycerine solutions, water‐butanol solutions, and water‐sodium lauryl sulfate solutions. Agreement is obtained between theory and experiment.

Platelet activating factor (PAF) antagonists: synthesis and structure-activity studies of novel PAF analogs modified in the phosphorylcholine moiety (1989)

New analogues of platelet activating factor (PAF), in which the phosphate and trimethylammonium moieties were replaced with an acylcarbamoyl moiety and a quaternary cyclic ammonium group, were synthesized. Their biological activities as PAF antagonists were evaluated by the inhibition of PAF-induced rabbit platelet aggregation in vitro and protective effects on PAF-induced hypotension in rats and PAF-induced death in mice. Investigation of structure-activity relationships revealed that PAF antagonist activity is strongly influenced by the acyl substituent of the nitrogen atom on the carbamoyl group and the nature of the polar head group at the 3-position of the glycerin backbone. Among the compounds tested, 2-[[N-acetyl-N-[[2-methoxy-3-[ (octadecylcarbamoyl)oxy]propoxy]-carbonyl]amino] methyl]-1-ethylpyridinium chloride (21, CV-6209) was one of the most potent compounds in the in vitro assay (IC50 = 7.5 X 10(-8) M) and the most potent and long-lasting in the in vivo assays. (R)-(-)-21 and (S)-(+)-21 were also synthesized, and no significant differences were observed in PAF antagonist activity in vitro and an inhibitory effect on PAF induced hypotension in vivo between (RS)-21 and its enantiomers.
Distribution of Ground Fault Currents Along Transmission Lines -- An Improved Algorithm (1985)

The calculation of fault current distribution between ground wires and ground is important for the operation of modern power systems. A new method is presented based on an approach whereby the current distribution is solved through the computation of driving-point impedances. The method is applied to three phase systems with mutual couplings between conductors (phase and ground, respectively) included. Currents computed by this method and methods published in recent literature are compared and are found in good agreement. Results show that the method is more efficient in terms of CPU time and memory space.
How Many Pixels Does it Take to Make a Good 4” × 6” Print? Pixel Count Wars Revisited (2012)

This paper explores why larger pixels and sensors are key to the future of DSCs. It also looks at how aliasing artifacts are created as a function of the relationship between the optical spread function of the lens, the pixel size and the presence of a color filter array.
Index of supplementary files from "Perils of Zero-Interaction Security in the Internet of Things" (2019)

This record serves an an index to the other dataset releases that are part of the paper "Perils of Zero Interaction Security in the Internet of Things" by Mikhail Fomichev, Max Maass, Lars Almon, Alejandro Molina, Matthias Hollick, in Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies, vol. 3, Issue 1. We have chosen to split the dataset into several parts to meet Zenodo size requirements and make it easier to find specific pieces of data. In total, the following datasets exist: <strong>Raw data</strong><br> These datasets contain raw data, as collected directly from the devices doing the recording. It includes readings from several different sensors, as well as observed WiFi and BLE signals with their signal strength, and in one case, audio recordings. This raw data can be used to repeat our own experiments, or to apply different schemes to it to have a baseline for comparisons. Four datasets exist, mapped to the three scenarios discussed in the paper: Car Scenario Office Scenario Mobile Scenario + audio data in separate deposit (with access control) <strong>Processed Data</strong><br> The processed data is generated from the raw data using the processing code (which can be found in the code repository). The resulting data contains computed features from the five papers under investigation plus derived machine learning datasets, and can be used to see in detail how the schemes behave in specific situations. These datasets tend to be fairly large. Three datasets exist: Car Scenario Office Scenario Mobile Scenario <strong>Result Data</strong><br> Finally, the result datasets contain the results of the evaluation (i.e., the computed error rates and generated plots, plus associated caches). The code used to derive these results can once again be found in the source code repository. Here, five datasets exist, one for each investigated paper: Karapanos et al.

Constituents of Domestic Citrus Plants. Part XXVI. Studies on the Constituents of Yalaha. Structures of a New Acridone Alkaloid and Two New Coumarins. (1996)

A new acridone alkaloid, 1, 3, 5-trihydroxy-10-methylacridone (8), and two new coumarins, trans-clausarinol (9) and khelmarin-D (11), were isolated from the root of Yalaha [several hybrid seedlings resulting from a cross of Duncan grapefruit (Citrus paradisi MACF.)×Dancy tangerine (C. tangerina HORT. ex TANAKA)], and structures were determined on the basis of spectroscopic evidence. Seventy known coumarins, acridone alkaloids and miscellaneous compounds were also characterized.

75th anniversary of the Stiles–Crawford effect(s): a celebratory special symposium: October 23 2008, Rochester, New York (2009)

There are rather few articles which, so-to-speak, serve to change the landscape in a scientific field. One of those was the discovery of the "directional sensitivity of the retina" by Walter Stanley Stiles and Brian Hewson Crawford (first reported in 1933). Subsequently, their findings were subdivided by Hansen into two logical components, "the Stiles-Crawford Effects of the First and Second Kinds, (SCE- 1 and SCE-2)." The former (SCE-1) dealt with aspects of their research which addressed alterations in perceived brightness of a visual stimulus; the second (SCE-2) was associated with the perceived hue and saturation of these visual stimuli. These discoveries arose out of a failed attempt by W.S. Stiles and B.H. Crawford to measure properly the areas of the entrance pupils of their experimental subjects as part of a research program which addressed problems of glare, e.g., disability glare, in illuminating engineering. Their research was conducted at the National Physical Laboratory (NPL), which is located in Teddington, Middlesex, England. These two fine scientists properly deduced the reason for the failure of their experimental design, and they effectively described and defined a new feature of the visual system which was largely ascribed to the retina. In time, it was realized that this phenomenon was associated in large measure with the waveguide/fiber-optics properties of photoreceptors, and that this was a feature shared by virtually all vertebrate species. This paper is divided into two parts. In the first part, Enoch describes, as best he can, the culture and working conditions at NPL during 1959/60 when he served as a post-doctoral fellow with W.S. Stiles. And in the second part of this paper, the authors describe the findings of W.S. Stiles and B.H. Crawford at the time of their discovery. Today, we celebrate the 75th Anniversary of that research. The organizing committee for this program (alphabetically) is David Atchison, Jay M. Enoch, Vasudevan Lakshminarayanan, and Pieter Walraven. Our group of speakers today will follow with discussions of aspects of subsequent work which has evolved from the initial discoveries made by the late W.S. Stiles and B.H. Crawford.
Natriuretic peptides. (2002)

Thus the natriuretic peptides represent an important class of molecules in patients with congestive symptoms. As such, natriuretic peptide measurements can assist in the evaluation of patients with heart failure or to exclude this as a cause in patients with dyspnea. Increasing the levels of natriuretic peptides may offer an important therapeutic advance in patients with heart failure.
Characterization of boron doped nanocrystalline diamonds (2008)

Nanostructured diamond doped with boron was prepared using a hot-filament assisted chemical vapour deposition system fed with an ethyl alcohol, hydrogen and argon mixture. The reduction of the diamond grains to the nanoscale was produced by secondary nucleation and defects induced by argon and boron atoms via surface reactions during chemical vapour deposition. Raman measurements show that the samples are nanodiamonds embedded in a matrix of graphite and disordered carbon grains, while morphological investigations using field electron scanning microscopy show that the size of the grains ranges from 20 to 100 nm. The lowest threshold fields achieved were in the 1.6 to 2.4 V/μm range.
Characterization of Hydrogen Peroxide and Superoxide Degrading Pathways of<i>Aspergillus Niger</i>Catalase: A Steady-State Analysis (1994)

The oxidized intermediates generated upon exposure of Aspergillus niger catalase to hydrogen peroxide and superoxide radical fluxes were examined with UV-visible spectrophotometry. Hydrogen peroxide and superoxide radical were generated by means of glucose/glucose oxidase and xanthine/xanthine oxidase systems. Serial overlay of absorption spectra in the Soret (350-450 nm) and visible regions (450-700 nm) showed that the decomposition of hydrogen peroxide by the catalase of Aspergillus niger can proceed through one of two distinct pathways: (i), the normal "catalatic" cycle consisting of ferric catalase-->Compound I-->ferric catalase; (ii), a longer cycle where superoxide radical transforms Compound I to Compound II which is then converted to the resting ferric enzyme via Compound III. The latter sequence of reactions ensures that the catalase of Aspergillus niger restores entirely its activity upon exposure to low levels of superoxide radicals due to the actions of oxidases.
Clinical Trial Registration in Physiotherapy Journals: Recommendations From the International Society of Physiotherapy Journal Editors (2012)

Clinical trial registration involves placing the protocol for a clinical trial on a free, publicly available, and electronically searchable register. Registration is considered to be prospective if the protocol is registered before the trial commences (ie, before the first participant is enrolled). Prospective registration has several potential advantages. It could help avoid trials being duplicated unnecessarily and it could allow people with health problems to identify trials in which they might participate. Perhaps more importantly, however, it tackles 2 big problems in clinical research: selective reporting and publication bias. Prospective clinical trial registration is of great potential value to the clinicians, consumers, and researchers who rely on clinical trial data, and that is why the International Society of Physiotherapy Journal Editors (ISPJE) is recommending that members enact a policy for prospective trial registration.
