Anisotropic dielectric properties of media containing aligned nonspherical scatterers (1985)

Electromagnetic wave propagation in a medium containing a random distribution of aligned, pair-correlated nonspherical scatterers is studied using the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T</tex> -matrix to characterize the single scatterer response, the quasicrystalline approximation (QCA) and the correlation function. The resulting dispersion equation for the average medium is numerically solved as a function of frequency and the direction of propagation. Numerical results are presented for the attenuation of electromagnetic waves versus frequency, concentration, and direction of propagation.
Auditory Feedback and Song Production Do Not Regulate Seasonal Growth of Song Control Circuits in Adult White-Crowned Sparrows (2007)

An important area of research in neuroscience is understanding what properties of brain structure and function are stimulated by sensory experience and behavioral performance. We tested the roles of experience and behavior in seasonal plasticity of the neural circuits that regulate learned song behavior in adult songbirds. Neurons in these circuits receive auditory input and show selective auditory responses to conspecific song. We asked whether auditory input or song production contribute to seasonal growth of telencephalic song nuclei. Adult male Gambel's white-crowned sparrows were surgically deafened, which eliminates auditory input and greatly reduces song production. These birds were then exposed to photoperiod and hormonal conditions that regulate the growth of song nuclei. We measured the volumes of the nuclei HVC, robust nucleus of arcopallium (RA), and area X at 7 and 30 d after exposure to long days plus testosterone in deafened and normally hearing birds. We also assessed song production and examined protein kinase C (PKC) expression because previous research reported that immunostaining for PKC increases transiently after deafening. Deafening did not delay or block the growth of the song nuclei to their full breeding-condition size. PKC activity in RA was not altered by deafening in the sparrows. Song continued to be well structured for up to 10 months after deafening, but song production decreased almost eightfold. These results suggest that neither auditory input nor high rates of song production are necessary for seasonal growth of the adult song control system in this species.
Feasibility of Obtaining GPS/PAM-DII Telemetry from PKM Ignition through PAM-DII Separation (1986)

&lt;div class="htmlview paragraph"&gt;The Shuttle version of the NAVSTAR Block II Global Positioning System (GPS) Space Vehicle (SV) will be injected into the transfer orbit with a Perigee Kick Motor (PKM) contained in an attached PAM-DII stage. Mission “drift” orbit injection will occur near the 4th apogee of the transfer orbit with an Apogee Kick Motor (AKM) burn. Final mission orbit will be attained following any necessary corrections by the Reaction Control System (RCS) which will also be used throughout the SV lifetime for orbit maintenance. A primary concern in the transfer procedure is GPS/PAM-DII separation following PKM burnout because of the possibility of SV and PAM-DII recontact if large coning angles have developed during the burn. Hence, initial flights will need substantial instrumentation to monitor PKM burn and separation data. The most desirable method of instrumentation readout is by telemetry transmission to an Air Force Remote Tracking station (RTS). This paper shows that the PKM burn can be planned to occur within the field of view of an RTS within the desired look angle constraints. A detailed example and an extensive series of mission planning charts are also provided.&lt;/div&gt;
Local field potential activity dynamics in response to deep brain stimulation of the subthalamic nucleus in Parkinson's disease (2020)

Local field potentials (LFPs) may afford insight into the mechanisms of action of deep brain stimulation (DBS) and potential feedback signals for adaptive DBS. In Parkinson's disease (PD) DBS of the subthalamic nucleus (STN) suppresses spontaneous activity in the beta band and drives evoked resonant neural activity (ERNA). Here, we investigate how STN LFP activities change over time following the onset and offset of DBS. To this end we recorded LFPs from the STN in 14 PD patients during long (mean: 181.2 s) and short (14.2 s) blocks of continuous stimulation at 130 Hz. LFP activities were evaluated in the temporal and spectral domains. During long stimulation blocks, the frequency and amplitude of the ERNA decreased before reaching a steady state after ~70 s. Maximal ERNA amplitudes diminished over repeated stimulation blocks. Upon DBS cessation, the ERNA was revealed as an under-damped oscillation, and was more marked and lasted longer after short duration stimulation blocks. In contrast, activity in the beta band suppressed within 0.5 s of continuous DBS onset and drifted less over time. Spontaneous activity was also suppressed in the low gamma band, suggesting that the effects of high frequency stimulation on spontaneous oscillations may not be selective for pathological beta activity. High frequency oscillations were present in only six STN recordings before stimulation onset and their frequency was depressed by stimulation. The different dynamics of the ERNA and beta activity with stimulation imply different DBS mechanisms and may impact how these activities may be used in adaptive feedback.
Enzyme and Earthworm Activities during Vermicomposting of Carbaryl‐Treated Sewage Sludge (1999)

Abstract The feasibility of vermicomposting pesticide contaminated refuses was evaluated. A mixture of sewage sludges was amended, at a ratio of 1:1 (v/v), with a garden refuse artificially contaminated with carbaryl, a carbamate insecticide commonly used in farming and gardening. Ten clitellated earthworms were then placed in this material. We determined the evolution of earthworm ( Eisenia foetida , Savigny) biomass and changes in enzyme activities during an 18‐wk period of sewage sludge vermicomposting. The carbaryl produced a chronically toxic effect on the earthworms, measured by weight gain and sexual maturity. The growth was slower in the presence of pesticide. In addition, carbaryl treatments showed inhibited enzyme activity in the first weeks of the vermicomposting process, slowing down organic matter biodegradation. The dynamics of the vermicomposting process can be followed by combining easily detectable parameters related to the global microbial metabolism: a traditional chemical (water‐soluble C/water‐soluble N) and biochemical (dehydrogenase activity/water‐soluble C) index, were calculated. In particular, this last seemed more useful in characterizing the vermicomposting process even a longer maturation time (10–18 wk).
Cdc37 is required for association of the protein kinase Cdc28 with G1 and mitotic cyclins. (1995)

Studies of the temperature-sensitive cdc37-1 mutant of Saccharomyces cerevisiae suggest that Cdc37 is required for passage through the G1 phase of the cell cycle, but its precise function is not known. We have investigated the role of Cdc37 in the regulation of the cyclin-dependent protein kinase Cdc28. We find that G1 arrest in the cdc37-1 mutant is accompanied by a decrease in the Cdc28 activity associated with the G1 cyclin Cln2. This defect appears to be caused by a decrease in the binding of Cdc28 and Cln2. cdc37-1 mutants also exhibit a defect in the binding and activation of Cdc28 by the mitotic cyclin Clb2. Thus Cdc37 may be a regulator that is required for the association of Cdc28 with multiple cyclins.
AutoPandas: neural-backed generators for program synthesis (2019)

Developers nowadays have to contend with a growing number of APIs. While in the long-term they are very useful to developers, many modern APIs have an incredibly steep learning curve, due to their hundreds of functions handling many arguments, obscure documentation, and frequently changing semantics. For APIs that perform data transformations, novices can often provide an I/O example demonstrating the desired transformation, but may be stuck on how to translate it to the API. A programming-by-example synthesis engine that takes such I/O examples and directly produces programs in the target API could help such novices. Such an engine presents unique challenges due to the breadth of real-world APIs, and the often-complex constraints over function arguments. We present a generator-based synthesis approach to contend with these problems. This approach uses a program candidate generator, which encodes basic constraints on the space of programs. We introduce neural-backed operators which can be seamlessly integrated into the program generator. To improve the efficiency of the search, we simply use these operators at non-deterministic decision points, instead of relying on domain-specific heuristics. We implement this technique for the Python pandas library in AutoPandas. AutoPandas supports 119 pandas dataframe transformation functions. We evaluate AutoPandas on 26 real-world benchmarks and find it solves 17 of them.

ChromAIX: Fast energy resolved photon-counting readout electronics for future human Computed Tomography (2010)

ChromAIX is an ASIC for fast single photon-counting designed to study the feasibility of energy-resolved photon-counting human Spectral CT. It allows for reading out 4 × 16 pixels of a direct converting sensor made of Cd[Zn]Te with a pixel pitch of about 300μm. It supports K-edge imaging [3]. After thorough electrical testing reported in [6] characterization under g- and X-rays was done giving promising results as to the behavior of the ASIC, and revealing the known limitations of direct conversion material (flux limitation, polarization behavior). Measurements with g- and X-rays are compared with simulation results, and good correspondence is obtained.
Organically Modified Layered Silicates as Reinforcing Fillers for Natural Rubber (2002)

Rubber compounds based on natural rubber containing organically modified montmorillonites were prepared. The state of dispersion of the clay was characterized by scanning and transmission electron microscopies, and the spacings between the silicate layers were evaluated by X-ray diffraction. The effect of the addition of clay on the elastomeric compound was analyzed through mechanical and swelling properties and also through the determination of polymer chain orientation during elongation.
Paper No S7.3: Holographic Direct View System With 4K2K LCOS SLM and LED Reconstruction Light Source (2015)

Abstract Instead of using laser as light source to generate hologram, light‐emitting diode (LED) was used together with 4K2K liquid crystal on silicon (LCOS) panel to reconstruct LED light and enter computer generated hologram to LCOS panel, to generate interface pattern. Near eye holographic display is produced with off axis optical structure. 4K2K panel diffraction efficiency comparison between LED and laser is also measured.
An age-related homeostasis mechanism is essential for spontaneous amelioration of hemophilia B Leyden (2009)

Regulation of age-related changes in gene expression underlies many diseases. We previously discovered the first puberty-onset gene switch, the age-related stability element (ASE)/age-related increase element (AIE)-mediated genetic mechanism for age-related gene regulation. Here, we report that this mechanism underlies the mysterious puberty-onset amelioration of abnormal bleeding seen in hemophilia B Leyden. Transgenic mice robustly mimicking the Leyden phenotype were constructed. Analysis of these animals indicated that ASE plays a central role in the puberty-onset amelioration of the disease. Human factor IX expression in these animals was reproducibly nullified by hypophysectomy, but nearly fully restored by administration of growth hormone, being consistent with the observed sex-independent recovery of factor IX expression. Ets1 was identified as the specific liver nuclear protein binding only to the functional ASE, G/CAGGAAG, and not to other Ets consensus elements. This study demonstrates the clinical relevance of the first discovered puberty-onset gene switch, the ASE/AIE-mediated regulatory mechanism.

Discrimination between active and latent tuberculosis based on ratio of antigen-specific to mitogen-induced IP-10 production (2015)

Mycobacterium tuberculosis is the major causative agent of tuberculosis (TB). The gamma interferon (IFN-γ) release assay (IGRA) has been widely used to diagnose TB by testing cell-mediated immune responses but has no capacity for distinguishing between active TB and latent TB infection (LTBI). This study aims to identify a parameter that will help to discriminate active TB and LTBI. Whole-blood samples from 33 active TB patients, 20 individuals with LTBI, and 26 non-TB controls were applied to the commercial IFN-γ release assay, QuantiFERON-TB Gold In-Tube, and plasma samples were analyzed for interleukin-2 (IL-2), IL-6, IL-8, IL-10, IL-13, tumor necrosis factor-alpha (TNF-α), IFN-γ, monokine induced by IFN-γ (MIG), interferon gamma inducible protein 10 (IP-10), interferon-inducible T cell alpha chemoattractant (I-TAC), and monocyte chemoattractant protein 1 (MCP-1) by using a commercial cytometric bead array. The Mycobacterium tuberculosis antigen-specific production of most of the assayed cytokines and chemokines was higher in the active TB than in the LTBI group. The mitogen-induced responses were lower in the active TB than in the LTBI group. When the ratio of TB-specific to mitogen-induced responses was calculated, IL-2, IL-6, IL-10, IL-13, TNF-α, IFN-γ, MIG, and IP-10 were more useful in discriminating active TB from LTBI. In particular, most patients showed higher IP-10 production to Mycobacterium tuberculosis antigens than to mitogen at the individual level, and the ratio for IP-10 was the strongest indicator of active infection versus LTBI with 93.9% sensitivity and 90% specificity. In conclusion, the ratio of the TB-specific to the mitogen-induced IP-10 responses showed the most promising accuracy for discriminating active TB versus LTBI and should be further studied to determine whether it can serve as a biomarker that might help clinicians administer appropriate treatments.
Cloning and Characterization of Rat-brain-specific Transcripts: Rare, Brain-specific Transcripts and Tyrosine Hydroxylase (1983)

The sequence complexity of RNA from adult tissues of several rodents has been measured by saturation hybridization in which excess RNA is annealed to radioactive, single-copy DNA. In the rat (Shearer 1977; Chikaraishi et al. 1978; Grouse et al. 1978; Kaplan et al. 1978; Chikaraishi 1979; Lee et al. 1979; Wilkes et al. 1979; Beckmann et al. 1981; Kaplan and Finch 1982), mouse (Hahn and Laird 1971; Brown and Church 1972; Grouse et al. 1972; Bantle and Hahn 1976; Grady et al. 1978; Kuroiwa and Natori 1979; Van Ness et al. 1979), and rabbit (Brown and Church 1972; Church and Schultz 1974), the brain has consistently shown a higher complexity in both its nuclear and cytoplasmic RNAs compared with other tissues. Assuming asymmetric transcription, brain nuclear RNA possesses sequence complexity equivalent to between 31% (5.9 × 108 nucleotides in rat; Chikaraishi et al. 1978) and 42% (5.7 × 108 nucleotides...
Turbo-MIMO for wireless communications (2004)

This article reviews an important class of MIMO wireless communications, known collectively as turbo-MIMO systems. A distinctive property of turbo-MIMO wireless communication systems is that they can attain a channel capacity close to the Shannon limit and do so in a computationally manageable manner. The article focuses attention on a subclass of turbo-MIMO systems that use space-time coding based on bit-inter-leaved coded modulation. Different computationally manageable decoding (detection) strategies are briefly discussed. The article also includes computer experiments that are intended to improve the understanding of specific issues involved in the design of turbo-MIMO systems.

Vial Sharing of High-Cost Drugs to Decrease Leftovers and Costs: A Retrospective Observational Study on Patisiran Administration in Bologna, Italy (2023)

Waste of high-cost medicines, such as orphan drugs, is a major problem in healthcare, which leads to excessive costs for treatments. The main objective of this study was to evaluate the impact of a vial-sharing strategy for patisiran, an orphan drug used for the treatment of hereditary transthyretin-mediated amyloidosis, in terms of a reduction in the discarded drug amount and cost savings. The retrospective observational study was conducted in a tertiary referral center (Emilia-Romagna, Italy), between February 2021 and November 2022. Data on drug waste were calculated as "(mg used-mg prescribed)/mg prescribed" for each session. We found a statistically significant (-9.14%, <i>p</i> < 0.001, 95% CI 5.87-12.41) absolute difference in mean discarded drug rates per session based on the study phase (before and after vial-sharing introduction) at the two-sample t-test. The absolute difference corresponded to a percentage decrease in the average reduction in the discarded drug rate with vial sharing of 82.96% per session. On an annual scale, the estimated cost savings was EUR 26,203.80/year for a patient with a standard body weight of 70 kg. In conclusion, we demonstrated that a patisiran vial-sharing program undoubtedly offsets some of the high costs associated with this treatment. We suggest that this easy-to-introduce and cost-effective approach can be applied to the administration of other high-cost drugs.

Configuration Caching Techniques for FPGA (2000)

Although run-time reconfigurable systems have been shown to achieve very high performance, the speedups over traditional microprocessor systems are limited by the cost of hardware configuration. In this paper, we explore the idea of configuration caching. We present techniques to carefully manage the configurations present on the reconfigurable hardware throughout program execution. Through the use of the presented strategies, we show that the number of required reconfigurations is reduced, lowering the configuration overhead. We extend these techniques to a number of different FPGA programming models, and develop both lower bound and realistic caching algorithms for these structures. Introduction In recent years, reconfigurable computing systems such as Garp [Hauser97], OneChip [Wittig96] and Chimera [Hauck97] have attracted a lot of attention because of their promise to deliver the high performance provided by reconfigurable hardware along with the flexibility of general purp...
Determining the Drivers for Long Lead Times of Engineering Change Orders: A Data Mining Approach (2012)

In the automotive industry engineering change orders (ECOs) are responsible for a high proportion of development costs. An inefficient handling of them prolongs the time to market, which is widely regarded to be a key competitive factor and a cost driver.
Propionibacterium acnes Abundance Correlates Inversely with Staphylococcus aureus: Data from Atopic Dermatitis Skin Microbiome (2018)

The microbiome may influence disease severity in atopic dermatitis. The skin of atopic dermatitis patients and healthy individuals was sampled in a standardized manner and the microbial composition analysed using next-generation sequencing. Optical density measurements were used to investigate bacterial growth under defined conditions in vitro. Lesional skin from patients with atopic dermatitis had a higher abundance of Staphylococcus aureus and reduced quantities of Propionibacterium acnes and Lawsonella clevelandensis compared with non-lesional skin. The abundance of P. acnes correlated negatively with that of S. aureus (ρ= -0.6501, p < 0.0001). Fermentation products of P. acnes inhibited the growth of S. aureus and S. epidermidis. Serum from patients with atopic dermatitis inhibited the growth of S. aureus to a greater extent than did serum from healthy individuals. These results suggest that selective modification of the skin microbiome could potentially be used as a therapeutic strategy in atopic dermatitis.
Undergraduate and Postgraduate Development of Engineers of the Electricity Commission of New South Wales (1977)

This paper outlines the various methods used by the Electricity Commission of New South Wales to assist in the development of its undergraduate and graduate engineers. The major areas of endeavour are: A Cadet Scheme for engineering education, balanced between Universities and Institutes. The use of experienced engineers as Counsellors for each Cadet. Industrial training for Cadets and other undergraduates. In-service training of recent graduates. Support of staff undertaking postgraduate studies. Participation in schools conducted under the auspices of the Electricity Supply Association of Australia. These methods have been employed by the Commission over a number of years and have proved sufficiently worthwhile to be continues and expanded. It is hoped that other organisations might benefit from this account of the Commission's experience.
