Magnetic field analysis of permanent magnet motor with magnetoanisotropic materials Nd-Fe-B (2003)

In this paper, we propose the method to analyze the magnetization distribution in magnetoanisotropic materials by using the finite-element method considering the improved variable magnetization and Stoner-Wohlfarth model. By using this method, furthermore, the effect of the eddy currents induced in permanent magnets was analyzed. From the analyzed result, it is clarified how the magnetization distribution affects the performance of the surface permanent magnet-type motors.
Effect of moisture content on physical and flow properties of milk‐millet powders (2022)

Abstract The physical and flow properties of milk blended barnyard and foxtail millet powders were evaluated at different moisture contents. Particle‐size distribution and span decreased considerably as moisture increased. The d 0.5 increased from 24.769 to 38.642 μm in milk‐barnyard millet powder and from 27.942 to 41.063 μm in milk‐foxtail millet powder as moisture increased from 3 to 9%. The dynamic flow and shear tests revealed the hygroscopic nature of both millet powders, wherein moisture and particle size were found to influence flowability. The basic flow energy and shear tests proved that both millet powders would flow easily at 9% moisture content than at 3% due to agglomeration and reduction in contact surface area of the particles and the magnitude of their interactions. Compressibility and wall friction tests also corroborated the fact that milk‐millet powders were relatively more cohesive at 3% moisture, manifesting difficulties in flow. Between milk‐foxtail millet and milk‐barnyard millet powders, the former had better flowability due to its larger particle size and narrower span than the latter. Practical Applications Powders are dynamic systems whose behavior changes drastically with minor changes in the environment or moisture. In this study, the influence of moisture on physical and flow properties of milk‐millet powders were evaluated. The physical and flow properties of milk blended barnyard and foxtail millet powders were influenced by particle size and moisture content. The flow properties could be useful in understanding their behavior during handling, processing, and storage, and thus help in the design and optimization of processing and storage operations.
The 'Why?' of Mountain Climbing (2018)

The motivations of mountaineers may be a mystery to those who do not climb high mountains, and climbers themselves typically struggle to explain the forces that call these men and women into thin air. Bellingham resident, climber and author David Mauro offers his own answers to this “why?” question through pictures, video, and readings from his recent release, The Altitude Journals, recounting the seven-year period during which he traveled to each continent, climbing its highest summit.
Signal processing in the reflective acoustic microscope (1978)

We describe a new technique to enhance the image in the scanning acoustic microscope in the reflection mode. We use a 20 ns pulse modulated r.f. signal and a sampling oscilloscope to separate the incident signal from the reflected signal. The resulting image shows up details that are of the order of one micrometre with a good signal/noise ratio. We can further improve this resolution by phase measurements.

SMARTPHONE SECURITY EVALUATION - The Malware Attack Case (2011)

The adoption of smartphones, devices transforming from simple communication devices to ‘smart’ and multipurpose devices, is constantly increasing. Amongst the main reasons are their small size, their enhanced functionality and their ability to host many useful and attractive applications. However, this vast use of mobile platforms makes them an attractive target for conducting privacy and security attacks. This scenario increases the risk introduced by these attacks for personal mobile devices, given that the use of smartphones as business tools may extend the perimeter of an organization's IT infrastructure. Furthermore, smartphone platforms provide application developers with rich capabilities, which can be used to compromise the security and privacy of the device holder and her environment (private and/or organizational). This paper examines the feasibility of malware development in smartphone platforms by average programmers that have access to the official tools and programming libraries provided by smartphone platforms. Towards this direction in this paper we initially propose specific evaluation criteria assessing the security level of the well-known smartphone platforms (i.e. Android, BlackBerry, Apple iOS, Symbian, Windows Mobile), in terms of the development of malware. In the sequel, we provide a comparative analysis, based on a proof of concept study, in which the implementation and distribution of a location tracking malware is attempted. Our study has proven that, under circumstances, all smartphone platforms could be used by average developers as privacy attack vectors, harvesting data from the device without the users knowledge and consent.
GlycineN‐methyltransferase expression in the hippocampus and its role in neurogenesis and cognitive performance (2014)

The hippocampus is a brain area characterized by its high plasticity, observed at all levels of organization: molecular, synaptic, and cellular, the latter referring to the capacity of neural precursors within the hippocampus to give rise to new neurons throughout life. Recent findings suggest that promoter methylation is a plastic process subjected to regulation, and this plasticity seems to be particularly important for hippocampal neurogenesis. We have detected the enzyme GNMT (a liver metabolic enzyme) in the hippocampus. GNMT regulates intracellular levels of SAMe, which is a universal methyl donor implied in almost all methylation reactions and, thus, of prime importance for DNA methylation. In addition, we show that deficiency of this enzyme in mice (Gnmt-/-) results in high SAMe levels within the hippocampus, reduced neurogenic capacity, and spatial learning and memory impairment. In vitro, SAMe inhibited neural precursor cell division in a concentration-dependent manner, but only when proliferation signals were triggered by bFGF. Indeed, SAMe inhibited the bFGF-stimulated MAP kinase signaling cascade, resulting in decreased cyclin E expression. These results suggest that alterations in the concentration of SAMe impair neurogenesis and contribute to cognitive decline.
Evaluating Indirect Branch Handling Mechanisms in Software Dynamic Translation Systems (2007)

Software dynamic translation (SDT) systems are used for program instrumentation, dynamic optimization, security, intrusion detection, and many other uses. As noted by many researchers, a major source of SDT overhead is the execution of code which is needed to translate an indirect branch's target address into the address of the translated destination block. This paper discusses the sources of indirect branch (IB) overhead in SDT systems and evaluates several techniques for overhead reduction. Measurements using SPEC CPU2000 show that the appropriate choice and configuration of IB translation mechanisms can significantly reduce the IB handling overhead. In addition, cross-architecture evaluation of IB handling mechanisms reveals that the most efficient implementation and configuration can be highly dependent on the implementation of the underlying architecture

Lipid-based nanosystem of edaravone: development, optimization, characterization andin vitro/in vivoevaluation (2017)

Edaravone (EDR) is a well-recognized lipophilic free radical scavenger for diseases including neurodegenerative disease, cardiovascular disease, and cancer. However, its oral use is restricted due to poor oral bioavailability (BA). The aim of present research was to enable its oral use by developing a lipid-based nanosystem (LNS). The components of LNS including oil, surfactants, and co-surfactants were selected based on their potential to maximize the solubilization in gastrointestinal (GI) fluids, reduce its glucuronidation and improve transmembrane permeability. The liquid LNS (L-LNS) with Capryol™ PGMC (Oil), Cremophor<sup>®</sup> RH 40:Labrasol<sup>®</sup>:TPGS 1000 (1:0.8:0.2) (Surfactant) and Transcutol P<sup>®</sup> (Co-surfactant) were optimized to form microemulsion having droplet size (16.25 nm), polydispersity index (0.039), % Transmittance (99.85%), and self-emulsification time (32 s). It significantly improved the EDR loading as well as its metabolism and permeability profile during transport across the GI tract. To overcome the possible drawbacks of L-LNS, Aerosil<sup>®</sup> 200 was used to formulate solid LNS (S-LNS), and its concentration was optimized based on flow properties. S-LNS possessed all quality attributes of L-LNS confirmed by solid-state characterization, reconstitution ability, and stability study. The dissolution rate of EDR was significantly enhanced with L-LNS and S-LNS in simulated gastric, and intestinal fluids. The pharmacokinetic study revealed significant improvement in relative BA, C<sub>max</sub>, and t<sub>1/2</sub> with L-LNS and S-LNS against EDR suspension. Moreover, S-LNS showed superior cellular uptake and neuroprotective effect compared to EDR in SH-SY5Y695 cell line. An appropriate selection of the components of LNS could enable effective oral delivery of challenging therapeutics that are conventionally used by the parenteral administration.

Rhythmic synchronization tapping to an audio–visual metronome in budgerigars (2011)

In all ages and countries, music and dance have constituted a central part in human culture and communication. Recently, vocal-learning animals such as parrots and elephants have been found to share rhythmic ability with humans. Thus, we investigated the rhythmic synchronization of budgerigars, a vocal-mimicking parrot species, under controlled conditions and a systematically designed experimental paradigm as a first step in understanding the evolution of musical entrainment. We trained eight budgerigars to perform isochronous tapping tasks in which they pecked a key to the rhythm of audio-visual metronome-like stimuli. The budgerigars showed evidence of entrainment to external stimuli over a wide range of tempos. They seemed to be inherently inclined to tap at fast tempos, which have a similar time scale to the rhythm of budgerigars' natural vocalizations. We suggest that vocal learning might have contributed to their performance, which resembled that of humans.

Effective density and atomic number determined from diffraction profiles (2006)

X-ray diffraction (XRD) profiles are conventionally used to determine lattice spacings via Bragg's law in order to characterize crystalline materials. It does not appear to be widely known that they also permit compositional information, such as effective atomic number and a density descriptor, to be determined from materials having little or no crystal structure. A ratio method is introduced that relates x-ray scatter intensities in two adjacent momentum transfer bands of the diffraction profile corresponding to the "tip" region of the primary x-ray spectrum. It is shown that this ratio depends on the effective atomic number, Z, of the scattering sample. Conversely, Z may be derived from measurement of the ratio. Error sources in this ratio method are briefly analyzed. Once Z is known, the IAM (independent atom model) cross section can be extrapolated from the high momentum transfer region to lower values, where molecular interference effects manifest themselves in the XRD profile. This procedure enables the molecular interference function, <i>s(x)</i>, to be determined. On the assumption that the structure of liquids and amorphous materials can be represented by the hard sphere (HS) model, the packing fraction, &#951;, of atoms in the scattering sample can be ascertained from the second moment of <i>s(x)</i>. The effective atomic number, Z and the density descriptor, &#951;, usefully complement information provided by more traditional material analysis techniques based on XRD profiles.
Delta‐9‐tetrahydrocannabinol and synhexl: Effects on human sleep patterns (1972)

A series of experiments was conducted to determine the effects of orally administered 1‐trans‐Δ‐9‐ tetrahydrocannabinol (THC) on both undisturbed and experimentally altered (by rapid eye movement [REM] deprivation) sleep patterns of young adult male volunteers. In the deprivation experiments, the effects of a semisynthetic Δ‐6a‐10‐THC homologue, synhexl, were also studied. In the normative studies, 4 subjects received THC in doses ranging from 61 to 258 µg per kilogram shortly before sleep onset, while in the deprivation experiments 2 subjects received either THC (244 µg per kilogram and 259 µg per kilogram) or synhexl (733 µg per kilogram and 777 µg per kilogram) the morning after the second of 2 consecutive nights of REM deprivation. In both normative and deprivation experiments, all‐night sleep recordings were taken during base‐line, drug, and postdrug conditions. The results of both types of experiments were consistent in demonstrating increments in Stage 4 sleep and decrements in REM sleep. In the normative experiments, reduction in Stage 1 and time awake after sleep onset were observed at the highest dose level. Interpretation of these results and their relation to the effects of other psychoactive compounds upon sleep patterns are discussed.
AN ANALOGUE OF MET‐ENKEPHALIN ATTENUATES THE PITUITARY‐ADRENAL RESPONSE TO OVINE CORTICOTROPHIN RELEASING FACTOR (1986)

The met-enkephalin analogue, DAMME, suppresses the pituitary-adrenal axis in normal subjects; it is not clear whether this occurs at the level of the pituitary or above. We therefore administered synthetic ovine corticotrophin releasing factor (CRF-41) 100 micrograms i.v. to a group of normal male subjects, with or without pretreatment with DAMME 250 micrograms i.v., and monitored the response of plasma ACTH and serum cortisol. CRF-41 caused a marked stimulation of ACTH and cortisol release, but this was significantly attenuated by pretreatment with DAMME. It is therefore concluded that DAMME either directly inhibits the corticotroph at the level of the pituitary, or that it suppresses release of an additional factor which normally potentiates the action of CRF-41 on the pituitary.
A high resolution negative working resist, LMR‐UV, for g‐ and i‐line lithography (1991)

Abstract LMR‐UV (“low molecular weight resist for uv lithography”), a naphthoquinone‐diazide sulfonic acid ester of a novolak resin, is a negative working resist. The mechanism of insolubilization of LMR‐UV is based on the facts that the naphthoquinone‐diazide moiety is decomposed to indenecarboxylic acid (polar compound) by photolysis upon UV irradiation and that the irradiated resist film insolubilizes in a non‐polar developer. LMR‐UV reliably forms 0.6 μm lines and spaces over a reflective substrate with steps by using a g‐line stepper having a 0.35 NA lens. 0.6 μm‐wide aluminum patterns over topography are obtained by use of g‐line exposure and reactive ion etching. By use of an i‐line aligner (NA = 0.42), LMR‐UV resolves 0.25 μm space patterns with overhang profiles. The profiles are due to the large absorption coefficient of 3.8 μm −1 . 0.3 μm wide aluminum patterns are formed by i‐line exposure and lift‐off metallization.
Casimir companion: An invariant of motion for Hamiltonian systems (2013)

In this paper an invariant of motion for Hamiltonian systems is introduced: the Casimir companion. For systems with simple dynamical algebras (e.g., coupled spins, harmonic oscillators) our invariant is useful in problems that consider adiabatically varying the parameters in the Hamiltonian. In particular, it has proved useful in optimal control of changes in these parameters. The Casimir companion also allows simple calculation of the entropy of nonequilibrium ensembles.

Frequency response of solid-state impact ionization multipliers (2007)

A study of the frequency response of solid-state impact ionization multipliers (SIMs) is presented that emphasizes the role of resistive and capacitive elements of the device to establish response limitations. SIMs are designed to amplify input currents from an external source through the impact ionization mechanism. An equivalent circuit model for the SIM is developed based on its current versus voltage characteristics, which is used to derive a frequency response model. Theoretical frequency response matches very closely to measured responses for first generation SIM devices constructed on p-type silicon epitaxial layers with nickel silicide Schottky contact injection points. Devices were measured using a photodiode as a current source under light intensities between 74nA and 7.4μA. These SIMs were shown to have a low frequency response that follows a KT∕I relationship. Using an external photodiode with an effective capacitance of 6.8pF, frequency response for a 1.8μA input current was limited to 100kHz. A large effective barrier resistance due to the Schottky contact and 12kΩ space charge resistance dependent on device geometry dominate the response. Future SIM designs with higher frequency response will have to significantly lower both the input barrier resistance and space charge resistance.

Nmoc-DBHQ, a New Caged Molecule for Modulating Sarcoplasmic/Endoplasmic Reticulum Ca2+ ATPase Activity with Light Flashes (1997)

We report the synthesis and characterization of O[o-nitromandelyloxycarbonyl]-2,5-di(tert-butyl)hydroquinone (Nmoc-DBHQ), a new "caged" reagent for photoreleasing DBHQ, a membrane-permeant, reversible inhibitor of the sarcoplasmic/endoplasmic reticulum Ca2+ ATPase (SERCA). The Nmoc group is a new caging group developed for the current application. Photolysis of Nmoc-DBHQ proceeds with t1/2 = 126 +/- 2 micros, and t1/2 for subsequent release of DBHQ is estimated to be approximately 5 ms. Nmoc-DBHQ thus allows rapid and reversible modulation of SERCA activity in living cells. Through its acetoxymethyl ester, Nmoc-DBHQ can be loaded into cells easily by incubation. We demonstrate the use of Nmoc-DBHQ for photomodulating SERCA activity in fibroblasts and vagal sensory neurons. We further demonstrate the utility of pulsed DBHQ photorelease for probing and manipulating dynamic phenomena such as [Ca2+] oscillations in fibroblasts.
