PERCEPTUAL DISTANCE IN TIMBRE SPACE (2005)

This paper describes a perceptual space for timbre, defines an objective metric that takes into account perceptual orthogonality, and measures the quality of timbre interpolation applicable to perceptually valid timbral sonification. We discuss two timbre representations and measure perceptual judgment. We determined that a timbre space based on Mel-frequency cepstral coefficients (MFCC) is a good model for perceptual timbre space. 1.1. Goal and motivation 1.

Measurement of $J/ψ\toγη_{\rm c}$ decay rate and $η_{\rm c}$ parameters at KEDR (2014)

Using the inclusive photon spectrum based on a data sample collected at the $J/ψ$ peak with the KEDR detector at the VEPP-4M $e^+e^-$ collider, we measured the rate of the radiative decay $J/ψ\toγη_{\rm c}$ as well as $η_{\rm c}$ mass and width. Taking into account an asymmetric photon lineshape we obtained $Γ^0_{γη_{\rm c}}=2.98\pm0.18 \phantom{|}^{+0.15}_{-0.33}$ keV, $M_{η_{\rm c}} = 2983.5 \pm 1.4 \phantom{|}^{+1.6}_{-3.6}$ MeV/$c^2$, $Γ_{η_{\rm c}} = 27.2 \pm 3.1 \phantom{|}^{+5.4}_{-2.6}$ MeV.
Low-power UHF-RFID sensor tags for a complete monitoring and traceability of the cold chain (2012)

This paper focuses on the development of an intelligent monitoring system for logistic management. The system is a profitable combination of Radio-Frequency-Identification (RFID) Technology and variable sensor types, like temperature, humidity or gas sensors. Depending on the requirements, the integration of different sensors is possible. In this case the main attention is turned on the temperature monitoring in truck environment during the food transport. Of course, the setting is transferable on other applications like monitoring temperature of pharmaceuticals or controlling of humidity to prevent corrosion of car components during transport. Furthermore, the system is capable to communicate with the driver's cabin and with a central base in case of temperature range violation, allowing the driver or the fleet manager to proactively intervene before damage occurs.
Characterisation of nonlinear 2-ports for the design of class-C amplifiers (1977)

A method of characterising a nonlinear 2-port based on the ‘multiple-sinusoid-input describing function’ technique is proposed. For simplicity, the effects of the third and higher harmonics are ignored and the nonlinear 2-port is treated as a linear 4-port. The S-parameters of the 4-port are measured, and the ‘effective’ 5-parameters of the nonlinear 2-port are expressed in terms of the 2nd-harmonic terminations. The effects of the 2nd-harmonic reactance terminations on the fundamental-frequency 5-parameters are investigated, and a strategy for optimising the performance of a class-C amplifier is described.
Studies on the Relative Resistance of Some Soybean Varieties Against Whitefly and its Population Fluctuations During the Crop Season (2000)

Twenty three varieties of soybean were sown in two experiments in the experimental area of Oilseed Programme, National Agricultural Research Centre, Islamabad in a randomized complete block design. The experimental unit was 61,8 m. The varieties in Experiment No.1 attained maturity in ten weeks while they took eight weeks in Experiment No. 2. The whitefly population was usually observed on the upper fresh leaves of soybean whereas no or very little whitefty population was observed on the lower and middle leaves of the plant. Heavy rains proved to be lethal for whitefly and a sharp decline in its population was recorded after rains. The significant differences were recorded in the whitefly population amongst the varieties in both the experiments. The susceptibility and resistance of different varieties against whitefly varied in different weeks. In the first week, CO-1 proved to be most resistant in Experiment No.1, while G-9956 showed maximum resistance to whitefly in the 2nd and 3rd weeks. As a whole, AGS-129 was the most susceptible variety with an average seasonal population of 0_74 whiteflies per leaf in Experiment No.1 while G-9956 proved to be most resistant with an average seasonal population of 0.19 whiteflies per leaf. Among the 11 varieties sown in Experiment No. 2. RAWAL-1 was recorded as the most susceptible variety with an average seasonal population of 1.08 whiteflies per leaf. AGS-344 proved to be most resistant with an average seasonal population of 0.10 whiteflies per leaf. The data on plant growth revealed no direct relation between number of nodes per plant and their respective plant heights. A plant having more number of nodes may have less height and vice versa. Similarly, a plant having maximum number of nodes or height in the initial stages of growth may not have maximum number of nodes or height at maturity.
Reactions of Surface Amines with Heterobifunctional Cross-Linkers Bearing Both Succinimidyl Ester and Maleimide for Grafting Biomolecules (2004)

Surface reactions of amines with a series of heterobifunctional cross-linkers containing both maleimide and succinimidyl ester groups were investigated with infrared reflection absorption spectroscopy (IRRAS), X-ray photoelectron spectroscopy (XPS), and near-edge X-ray absorption fine structure spectroscopy (NEXAFS). A specific surface derived from N-succinimidyl 6-maleimidylhexanoate (SMH) presents two linking groups, maleimide and succinimidyl ester, while surfaces from other cross-linkers present predominantly maleimide-pendant groups. An expected surface product by reaction of the cystamine monolayer with SMH, N,N‘-bis(6-maleimidylhexanoyl)cystamine (BMHC), was synthesized independently, self-assembled, and characterized for further supporting the above conclusion. Finally, a peptide, H-Gly-Arg-Gly-Asp-Ser-Pro-Cys-OH (GRGDSPC), was immobilized on a maleimide-pendant surface as an amino-terminated structure and on a binary group (maleimide and succinimidyl ester) modified surface as a bridging structure.
On the combinability of evidence in the Dempster-Shafer theory (1986)

In the current versions of the Dempster-Shafer theory, the only essential restriction on the validity of the rule of combination is that the sources of evidence must be statistically independent. Under this assumption, it is permissible to apply the Dempster-Shafer rule to two or more distinct probability distributions.

An essential step in the Dempster-Shafer rule of combination of evidence is that of normalization. The validity of normalization is open to question, particularly in application to probability distributions (Zadeh, 1976). At this juncture, the validity of normalization is a controversial issue.

In this paper, we construct a relational model for the Dempster-Shafer theory which greatly simplifies the derivation of its main results and cast considerable light on the validity of the rule of combination. The relational model is augmented with what is called the ball-box analogy, yielding an intuitively simple way of visualizing the concepts of belief and plausibility.
Immuno-Electron Microscopic Observations on Plasmodium Knowlesi Sporozoites: Localization of Protective Antigen and its Precursors (1984)

Cryoultramicrotomy, an antisporozoite monoclonal antibody (2G3) and protein A-gold particles were used to determine the distribution of the protective surface antigen (Pk 42) of sporozoites of Plasmodium knowlesi and its precursors (Pk 52 and Pk 50). Gold particles bound uniformly to both the outer plasma and the inner pellicular membranes, indicating a uniform distribution of antigen on these membranes. Intracellular gold particles were frequently found to be associated with micronemes, but less frequently with rhoptries. Limited proteolysis of P. knowlesi sporozoites totally eliminated binding of label to the outer plasma membrane. In contrast, distribution of label on the inner pellicular membranes, rhoptries, and micronemes of trypsinized sporozoites was relatively unaltered. On the basis of the present and earlier data obtained upon metabolic labeling of these parasites, it is likely that the antigen associated with the intracellular organelles corresponds to the precursor polypeptides Pk 52 and Pk 50.

The paper describes the theory of voltage space vector PWM in three-level inverter. The necessary and sufficient conditions for waveforms, such as synchronization, three phase symmetry (TPS), half-wave symmetry (HWS) and quarter-wave symmetry (QWS) are presented. Different strategies and realization methods are introduced. Simulation waveforms of voltage, current and corresponding harmonic spectrum are offered. The comparative results show that simulation results with proposed methods is in accordance with the experimental results seriously.

Silicates, Silicate Weathering, and Microbial Ecology (2001)

Mineralogy, microbial ecology, and mineral weathering in the subsurface are an inti-mately linked biogeochemical system. Although bacteria have been implicated indirectly in the accelerated weathering of minerals, it is not clear if this interaction is simply the coincidental result of microbial metabolism, or if it represents a speci c strategy of-fering the colonizing bacteria a competitive ecological advantage. Our studies provide evidence that silicate weathering by bacteria is sometimes driven by the nutrient re-quirements of the microbial consortium, and therefore depends on the trace nutrient content of each aquifer mineral. This occurrence was observed in reducing groundwa-ters where carbon is abundant but phosphate is scarce; here, even resistant feldspars are weathered rapidly. This suggests that the progression of mineral weathering may be in uenced by a mineral’s nutritional potential, with microorganisms destroying only bene cial minerals. The rock record, therefore, may contain a remnant mineralogy that re ects earlymicrobial destruction of biologically valuableminerals, leaving a residuum of “useless”minerals, where “value ” depends on the organism, its metabolic needs, and the diagenetic environment. Conversely, the subsurface distribution of microorganisms may, in part, be controlled by the mineralogy and by the ability of an organism to take advantage of mineral-bound nutrients. Keywords microbial geochemistry, phosphate, silicate weathering Interest in the microbial ecology of subsurface environments has grown tremendously in the past 10 years, and viable microorganisms have been recovered from a wide range of
Pay-As-You-Drive Pricing For Insurance Affordability (2011)

This paper describes how Pay-As-You-Drive (PAYD) pricing can increase vehicle insurance affordability. With conventional pricing, motorists pay a fixed premium for unlimited mileage coverage. PAYD charges premiums by the vehicle-mile, so a lowerrisk driver pays 2-4¢ per mile and a higher-risk driver pays 10-20¢ per mile. This lets motorists save money by reducing their mileage, and tends to benefit lower-income motorists. Pay-As-You-Drive can be a consumer option, so motorists select the rate structure they prefer.
Ultrafast Local Sensing of Strain and Temperature with a Single Semiconductor Quantum Dot (2022)

Femtosecond pump-probe microscopy of individual semiconductor quantum dots reveals energy shifts induced by coherent strain waves and the transition to incoherent heating at the nanoscale.
Integrating Haptic Feedback into MobileLocation Based Services (2012)

Haptics is a feedback technology that takes advantage of the human sense of touch by applying forces, vibrations, and/or motions to a haptic-enabled device such as a mobile phone. Historically, human-computer interaction has been visual - text and images on the screen. Haptic feedback can be an important additional method especially in Mobile Location Based Services such as knowledge discovery, pedestrian navigation and notification systems. A knowledge discovery system called the Haptic GeoWand is a low interaction system that allows users to query geo-tagged data around them by using a point-and-scan technique with their mobile device. Haptic Pedestrian is a navigation system for walkers. Four prototypes have been developed classified according to the user’s guidance requirements, the user type (based on spatial skills), and overall system complexity. Haptic Transit is a notification system that provides spatial information to the users of public transport. In all these systems, haptic feedback is used to convey information about location, orientation, density and distance by use of the vibration alarm with varying frequencies and patterns to help understand the physical environment. Trials elicited positive responses from the users who see benefit in being provided with a “heads up” approach to mobile navigation. Results from a memory recall test show that the users of haptic feedback for navigation had better memory recall of the region traversed than the users of landmark images. Haptics integrated into a multi-modal navigation system provides more usable, less distracting but more effective interaction than conventional systems. Enhancements to the current work could include integration of contextual information, detailed large-scale user trials and the exploration of using haptics within confined indoor spaces.

Decline in Emergent and Urgent Care during the COVID-19 Pandemic (2020)

ABSTRACT Due to the ongoing coronavirus disease (COVID-19) pandemic, there are concerns that patients may be avoiding care for emergent and urgent health conditions due to fear of contagion or as an unintentional consequence of government orders to postpone “non-essential” services. We therefore sought to evaluate the effect of the COVID-19 pandemic on the number of patient encounters for select emergent or urgent diagnoses at a large tertiary-care academic medical center in Boston. Inpatient diagnoses included acute myocardial infarction (MI) and stroke, and outpatient but urgent diagnoses included new referrals for breast and hematologic malignancies. For each condition, we used a “difference-in-differences” approach to estimate the proportional change in number of encounters during the pandemic (March – April 2020) compared with earlier in the same year (January – February 2020), using equivalent periods in 2019 as a control. After the onset of the pandemic, we observed significant reductions in hospitalizations for MI (difference-in-differences estimate, 0.67; 95%CI, 0.46-0.96; P=0.04) and stroke (difference-in-differences estimate, 0.42; 95%CI, 0.28-0.65; P&lt;0.001) (Table). In the ambulatory setting, there was a reduction in referrals for breast cancer and hematologic cancers, but this did not reach statistical significance until the month after the onset of the pandemic. Our findings suggest an urgent need for public health messaging to ensure that patients continue to seek care for acute emergencies. In addition, decisions by health systems regarding when to reinitiate non-emergent care should carefully factor in the harms of delayed diagnosis and treatment occurring during the COVID-19 pandemic.
An HCI Principles based Framework to Support Deaf Community (2017)

Sign language is a communication language preferred and used by a deaf person to converse with the common people in the community. Even with the existence of the sign language, there exist a communication gap between the normal and the disable/deaf person. Some solutions such as sensor gloves already are in place to address this problem area of communication, but they are limited and are not covering all parts of the language as required by the deaf person for the ordinary person to understand what is said and wanted? Due to the lack of credibility of the existing solutions for sign language translation, we have proposed a system that aims to assist the deaf people in communicating with the common people of the society and helping, in turn, the disabled people to understand the healthy (normal people) easily. Knowing the needs of the users will help us in focusing on the Human Computer Interaction technologies for deaf people to make it further more a user-friendly and a better alternative to the existing technologies that are in place. The Human Computer Interface (HCI) concept of usability, empirical measurement and simplicity are the key consideration in the development of our system. The proposed Kinect System removes the need for physical contact to operate by using Microsoft Kinect for Windows SDK beta. The result shows that the It has a strong, positive and emotional impact on persons with physical disabilities and their families and friends by giving them the ability to communicate in an easy manner and nonrepetitive gestures.
In-Situ FTIR Kinetic Study in the Silylation of Low-k Films with Hexamethyldisilazane Dissolved in Supercritical CO2 (2015)

In-situ Fourier transform infrared spectroscopy measurements were obtained by using an innovative equipment to study the heterogeneous reaction between a hydrolyzed porous methylsilsesquioxane film and hexamethyldisilazane (HMDS) dissolved in CO2 at supercritical conditions. Gas and solid infrared signatures were separated to obtain kinetic information of the heterogeneous reaction. A two-step reaction mechanism was observed: a fast first step controlled by kinetics and a second step controlled by the diffusion of the HMDS inside the porous material. Infrared information was used to derive a rate law expression of the silylation reaction between HMDS and Si-OH. A first order of reaction relative to the concentration of hydrophilic sites was observed with activation energy of 51.85 ± 1.25 kJ/mol.
The critical hitch angle for jackknife avoidance during slow backing up of vehicle–trailer systems (2014)

We set out to answer the question: At what hitch angle does it become impossible for a vehicle and trailer to continue to backing up without getting into a jackknife? Jackknifing during backing up of trailers occurs when the hitch angle increases to a point such that the vehicle and trailer fold together about the hitch point like a jackknife. If the backward motion is continued, the jackknife effect progressively worsens, until the vehicle and trailer are in physical contact with each other. Jackknifing can result in traffic disruptions and wasted time, and can potentially cause damage or personal injury. Our goal is to analytically determine the ‘critical hitch angle’ (θcr), the hitch angle threshold beyond which a continued reverse motion causes an inescapable jackknifing. In this paper, we provide a formal definition of θcr for slow backing up of vehicle–trailer systems on a level solid surface, beyond which the vehicle must stop backing up and revert to forward motion in order to escape from jackknifing. The critical hitch angle is sub-categorised into Absolute (θcr, a) and Directional (θcr, d) critical hitch angles depending on the operating constraints and vehicle steering objectives. One solution for θcr is posed as a numerical solution to the steady-state conditions of the dynamic equations. The effects of such hitch angle limitations are demonstrated through simulation. Also, a warning system making use of the θcr is proposed. Such warning systems can assist drivers in avoiding jackknifing while backing up a vehicle–trailer system.
THz leaky lens antenna coupled KIDs for broadband imaging and spectroscopy (2013)

This contribution presents the first demonstration of a linear polarized ultra wide bandwidth antenna, the Leaky Lens Antenna, coupled to a Kinetic Inductance Detector (KID). The two of them function as an ultra sensitive receiver over a bandwidth ranging from 0.15 GHz to 1.5 THz. The system has been manufactured and characterized in terms of power efficiency, and radiation pattern properties. The agreement between the expectations and the measurements is excellent.
The secreted Ipa complex of Shigella flexneri promotes entry into mammalian cells. (1996)

The bacterial pathogen Shigella flexneri causes bacillary dysentery in humans by invading coloncytes. Upon contact with epithelial cells, S. flexneri elicits localized plasma membrane projections sustained by long actin filaments which engulf the microorganism. The products necessary for Shigella entry include three secretory proteins: IpaB, IpaC, and IpaD. Extracellular IpaB and IpaC associate in a soluble complex, the Ipa complex. We have immunopurified this Ipa complex on latex beads and found that they were efficiently internalized into HeLa cells. Like S. flexneri entry, uptake of the beads bearing the Ipa complex was associated with membrane projections and polymerization of actin at the site of cell-bead interaction and was dependent on small Rho GTPases. These results indicate that a secreted factor can promote S. flexneri entry into epithelial cells.
Linear and nonlinear light scattering near the phase transition inKH2PO4 (1994)

The angular and temperature dependence of the linear light scattering and the temperature dependence of the second-harmonic nonlinear light scattering were studied in two different samples of ${\mathrm{KH}}_{2}$${\mathrm{PO}}_{4}$ (KDP) crystal: one from a zone close to the seed and another from a zone far from the seed. The angular dependence of the intensity of the linearly scattered light from the sample from the zone close to the seed shows a strong peak for the near Z(YX)Y scattering. This scattering originates from growth bands parallel to the (01\ifmmode\bar\else\textasciimacron\fi{}1) lattice planes in the pyramidal growth sector. The temperature dependence of the magnitude of this peak shows a considerable increase in the vicinity of the phase transition from the paraelectric to ferroelectric phase. Such an increase in the linear light scattering was not observed in the sample from the zone far from the seed. The anomalies related to the growth bands parallel to the (010) lattice planes in the prismatic growth sector were investigated also by second-harmonic light scattering. Here again a considerable increase in the intensity of the frequency-doubled scattered light was observed in the vicinity of the phase-transition temperature. The results of the light-scattering experiments are compared with an x-ray topographic study of the lattice defects.
A validated thermo mechanical FEM model of bead-on-plate welding (2014)

This paper is presenting accurate FEM model of bead-on-plate welds of 316L stainless steels through thermo-mechanical analysis. The model was composed using ANSYS Parametric Design Language (APDL) program. In thermal analysis, mixed mode of volumetric thermal load was used to represent moving heat source. Growing weld bead was accommodated in both the thermal and mechanical models using birth and death technique. Melting phenomenon was modelled by low stiffness and zero plastic strain of melting elements. Results from thermal analysis and subsequent mechanical analysis have been validated. Good agreements of predicted temperature histories, temperature field and residual stress with experimental results confirmed the accuracy of the proposed FEM model.
