Stationary Fourier transform spectrometer for use as a teaching tool (1994)

We report the design of a Fourier transform spectrometer with no moving parts. Its ease of alignment and inherent immunity to vibration make it an ideal instrument for use within the university teaching laboratory. A birefringent component is used to introduce a path difference which varies across the input aperture, and hence the interferogram is obtained in the spatial rather than the temporal domain. By way of example we present some spectra obtained from the instrument and suggest a number of experiments that give the student a heuristic appreciation of the Fourier transform function.
Enhancement of diffusers BRDF accuracy (2017)

This paper reports the result of an ESA study conducted at TNO to investigate properties of various diffusers. Diffusers are widely used in space instruments as part of the on-board absolute calibration. Knowledge of the behaviour of the diffuser is therefore most important. From measurements of launched instruments in-orbit it has been discovered that when a diffuser is used in the vacuum of space the BRDF can change with respect to the one in ambient conditions. This is called the air/vacuum effect and has been simulated in this study by measuring the BRDF in a laboratory in ambient as well as vacuum conditions. Another studied effect is related to the design parameters of the optical system and the scattering properties of the diffuser. The effect is called Spectral Features and is a noise like structure superimposed on the diffuser BRDF. Modern space spectrometers, which have high spectral resolution and/or a small field of view (high spatial resolution) are suffering from this effect. The choice of diffuser can be very critical with respect to the required absolute radiometric calibration of an instrument. Even if the Spectral Features are small it can influence the error budget of the retrieval algorithms for the level 2 products. in this presentation diffuser trade-off results are presented and the Spectral Features model applied to the optical configuration of the MERIS instrument is compared to in-flight measurements of MERIS.
Variability-Aware Latency Amelioration in Distributed Environments (2007)

Application designers of collaborative distributed virtual environments must account for the influence of the network connection and its detrimental effects on user performance. Based upon analysis and classification of existing latency compensation techniques, this paper introduces a novel approach to latency amelioration in the form of a two-tier predictor-estimator framework. The technique is variability-aware due to its proactive sender-side prediction of a pose a variable time into the future. The prediction interval required is estimated based on current and past network delay characteristics. This latency estimate is subsequently used by a Kalman filter-based predictor to replace the measurement event with a predicted pose that matches the event's arrival time at the receiving workstation. The compensation technique was evaluated in a simulation through an offline playback of real head motion data and network delay traces collected under a variety of real network conditions. The experimental results indicate that the variability-aware approach significantly outperforms a state-of-the-art one, which assumes a constant system delay
<title>Stray light design and analysis of the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) telescope</title> (1998)

The Sounding of the Atmosphere using Broadband Emission Radiometiy (SABER) instrument is a 10-channel earth limbviewing sensor that is to measure atmospheric emissions in the spectral range of 1.27 jm to 16.9 iim. Presented in this paper is the stray light design and analysis of SABER Unwanted radiation from the eaith and atmosphere are suppressed by the use of stiay light features that are Critical to mission success. These include the use ofan intermediate field stop, an inner and outer Lyot stop, and super-polished mirrors. The point source normalized irradiance transmission (PSNIT) curve, which characterizes the sensor's off-axis response, was computed using the stray light analysis program APART. An initial calculation of the non-rejected radiance (NRR) due to emissions and scatter from the earth and atmosphere was made using the PSNTT data. The results indicate that stray light will not impede the mission objectives.
Performance of uplink joint reception CoMP with antenna selection for reducing complexity in LTE-A systems (2015)

Coordinated Multi-point (CoMP) transmission and reception is considered as a promising technique to combat inter-cell interference, enhance throughput, improve mobility, reduce handover interruption time, and also to increase spectrum efficiency. In this paper, we investigate and analyze the performance of uplink intra-site joint reception CoMP (JR-CoMP) for LTE-Advanced (LTE-A) systems. Both single user-MIMO (SU-MIMO) CoMP and multiple user-MIMO (MU-MIMO) CoMP show significant gains in terms of cell average and cell-edge throughput performances. However, the complexity of JR-CoMP is a big concern for realistic systems. In this paper, we propose a novel and low-complexity JR-CoMP scheme which combines effective antenna selection (and is denoted as JR-CoMP-AS). Compared with original JR-CoMP, the proposed JR-CoMP-AS can significantly reduce the computational complexity with acceptable performance loss. Simulation results demonstrate and validate the advantage of the proposed JR-CoMP-AS scheme.
Pharmacologically Targeting the Fibroblast Growth Factor 14 Interaction Site on the Voltage-Gated Na+ Channel 1.6 Enables Isoform-Selective Modulation (2021)

Voltage-gated Na<sup>+</sup> (Na<sub>v</sub>) channels are the primary molecular determinant of the action potential. Among the nine isoforms of the Na<sub>v</sub> channel α subunit that have been described (Na<sub>v</sub>1.1-Na<sub>v</sub>1.9), Na<sub>v</sub>1.1, Na<sub>v</sub>1.2, and Na<sub>v</sub>1.6 are the primary isoforms expressed in the central nervous system (CNS). Crucially, these three CNS Na<sub>v</sub> channel isoforms display differential expression across neuronal cell types and diverge with respect to their subcellular distributions. Considering these differences in terms of their localization, the CNS Na<sub>v</sub> channel isoforms could represent promising targets for the development of targeted neuromodulators. However, current therapeutics that target Na<sub>v</sub> channels lack selectivity, which results in deleterious side effects due to modulation of off-target Na<sub>v</sub> channel isoforms. Among the structural components of the Na<sub>v</sub> channel α subunit that could be pharmacologically targeted to achieve isoform selectivity, the C-terminal domains (CTD) of Na<sub>v</sub> channels represent promising candidates on account of displaying appreciable amino acid sequence divergence that enables functionally unique protein-protein interactions (PPIs) with Na<sub>v</sub> channel auxiliary proteins. In medium spiny neurons (MSNs) of the nucleus accumbens (NAc), a critical brain region of the mesocorticolimbic circuit, the PPI between the CTD of the Na<sub>v</sub>1.6 channel and its auxiliary protein fibroblast growth factor 14 (FGF14) is central to the generation of electrical outputs, underscoring its potential value as a site for targeted neuromodulation. Focusing on this PPI, we previously developed a peptidomimetic derived from residues of FGF14 that have an interaction site on the CTD of the Na<sub>v</sub>1.6 channel. In this work, we show that whereas the compound displays dose-dependent effects on the activity of Na<sub>v</sub>1.6 channels in heterologous cells, the compound does not affect Na<sub>v</sub>1.1 or Na<sub>v</sub>1.2 channels at comparable concentrations. In addition, we show that the compound correspondingly modulates the action potential discharge and the transient Na+ of MSNs of the NAc. Overall, these results demonstrate that pharmacologically targeting the FGF14 interaction site on the CTD of the Na<sub>v</sub>1.6 channel is a strategy to achieve isoform-selective modulation, and, more broadly, that sites on the CTDs of Na<sub>v</sub> channels interacted with by auxiliary proteins could represent candidates for the development of targeted therapeutics.
Highly-Scalable Searchable Symmetric Encryption with Support for Boolean Queries. (2013)

This work presents the design, analysis and implementation of the first sub-linear searchable symmetric encryption (SSE) protocol that supports conjunctive search and general Boolean queries on symmetrically-encrypted data and that scales to very large data sets and arbitrarilystructured data including free text search. To date, work in this area has focused mainly on single-keyword search. For the case of conjunctive search, prior SSE constructions required work linear in the total number of documents in the database and provided good privacy only for structured attribute-value data, rendering these solutions too slow and inflexible for large practical databases. In contrast, our solution provides a realistic and practical trade-off between performance and privacy by efficiently supporting very large databases at the cost of moderate and welldefined leakage to the outsourced server (leakage is in the form of data access patterns, never as direct exposure of plaintext data or searched values). A key aspect of our protocols is that it allows the searcherto pivot its conjunctive search on the estimated least frequent keywordin the conjunction. We show that a decisional Diffie-Hellman (DDH) based pseudo-random function
Flow-based monitoring of GTP traffic in cellular networks (2012)

Network monitoring is becoming more important for network operators, due to increased interest in user tra�c pro�ling. Traditionally all these monitoring activities were performed in a packet-based manner, often using Deep
Packet Inspection (DPI). Due to the introduction of new laws that forbid the use of DPI, these packet-based techniques are currently at stake. This is one of the reasons why currently a shift is taking place from packet-based to flow-based measurement techniques. This work proposes a ow-based solution for monitoring packet-switched roaming tra�c, which is characterized by the GPRS Tunneling Protocol (GTP). The proposed solution is able to monitor both GTP v.0 and GTP v.1 tra�c in as well the control plane
as the user plane and uses IPFIX for the export of 
ow information. To demonstrate the feasibility of our solution we set up a proof of concept by developing an extension to the existing flow-based monitoring application
PMACCT. The proposed solution was validated in the testcenter of Dutch mobile operator KPN
Molecular Structure of Low Temperature Form of Triaminoguanidinium Nitrate (TAGN) (1993)

Abstract : A rigid-body motion study of triaminoguanidinium nitrate (TAGN) was initiated originally in order to determine if nitrate ion libration might be responsible for the TAGN fast burning rate. A low temperature polymorph of TAGN was discovered by this laboratory during the course of this rigid-body motion study. Continuation of this libration study in the lower temperature regime, however, necessitated understanding the molecular structure of the low temperature form of TAGN. To do this a signal-crystal x-ray diffraction structure determination of the low temperature form was undertaken. The crystal structure was determined including space group, lattice parameters, atomic coordinates and temperature factors, hydrogen bonding, and density.

A multichannel CSMA MAC protocol with receiver-based channel selection for multihop wireless networks (2002)

We propose a CSMA-based medium access control protocol for multihop wireless networks that uses multiple channels and a dynamic channel selection method. The proposed protocol uses one control channel and N data channels, where N is independent of the number of nodes in the network. The source uses an exchange of control packets on the control channel to decide on the best channel to send the data packet on. Channel selection is based on maximizing the signal-to-interference plus noise ratio at the receiver. We present performance evaluations obtained from simulations that demonstrate the effectiveness of the proposed protocol.
Application of 15N Nuclear Magnetic Resonance Spectroscopy to the Determination of the Stability of Aryl Nitrogen Mustards (1995)

An excellent correlation has been shown to exist between the 15N NMR chemical shifts of a series of aryl nitrogen mustards and the Hammett constant, sigma, which is much improved by the use of sigma-. These chemical shifts also correlate well with the hydrolysis rates of the compounds in 50% aqueous acetone at 66 degrees C and their alkylation of 4-(4'-nitrobenzyl)pyridine under similar conditions. Thus 15N NMR is a straightforward and material-conserving method for estimating the relative stabilities of aryl nitrogen mustards.
An efficient light converter YAB:Cr3+,Yb3+/Nd3+ with broadband excitation and strong NIR emission for harvesting c-Si-based solar cells (2014)

Plasmon-enhanced photoluminescence from bioconjugated gold nanoparticle and nanodiamond assembly (2011)

In this letter, we coupled nanodiamonds (NDs) with gold nanoparticles of different sizes using two complementary DNA sequences. After hybridizing the gold nanoparticles on the NDs, we observed the enhancement of the photoluminescence (PL) signals originating from the nitrogen-vacancy (N-V) center of the ND. The enhancement was attributed to the plasmon field created by the gold nanoparticles. The line shape of the enhanced PL spectra was also affected by the sizes of the attached nanoparticles due to their different resonant plasma frequencies. The signal enhancement can be used as an indexing tool for biosensing applications.
Potential for the Adoption of Probabilistic Risk Assessments by End-Users and Decision-Makers (2008)

ABSTRACT In the area of risk assessment associated with ecotoxicological and plant protection products, probabilistic risk assessment (PRA) methodologies have been developed that enable quantification of variability and uncertainty. Despite the potential advantages of these new methodologies, end-user and regulatory uptake has not been, to date, extensive. A case study, utilizing the Theory of Planned Behavior, was conducted in order to identify potential determinants of end-user adoption of probabilistic risk assessments associated with the ecotoxicological impact of pesticides. Seventy potential end-users, drawn from academia, government, industry, and consultancy organizations, were included in the study. The results indicated that end-user intention to adopt PRA varied across the different end-user groups. The regulatory acceptance of PRA was contingent on social acceptance across the regulatory community regarding the reliability and utility of the outputs. Training in interpretation of outputs is therefore highly relevant to regulatory acceptance. In other end-user sectors, a positive attitude toward PRA, “hands on” experience, and perceived capability of actually performing PRA is an important determinant of end-user intention to adopt PRA. It is concluded that training programs targeted to the specific needs of different end-user sectors should be developed if end-user adoption of PRA is to be increased.

Effects of crystalline menthol on blood metabolites in Holstein steers and in vitro volatile fatty acid and gas production1 (2016)

Fifty-two Holstein steers (573 ± 9.92 kg BW) were used to determine if oral administration of crystalline menthol would induce changes in endogenous secretions of IGF-1 and circulating concentrations of glucose, lactate, and plasma urea nitrogen (PUN). Steers were blocked by BW and assigned within block to treatment. Treatments consisted of 0, 0.003, 0.03, or 0.3% crystalline menthol (DM basis) added to the diet. Animals were housed in individual, partially covered pens equipped with feed bunks and automatic water fountains. On d 1 of the experiment, blood samples were obtained via jugular venipuncture at 0, 6, 12, 18, and 24 h after feeding. Treatment administration commenced on d 2, and blood samples were again drawn at 0, 6, 12, 18, and 24 h after feeding. This blood-sampling schedule was repeated on d 9, 16, 23, and 30. Plasma was analyzed for PUN, glucose, and lactate concentrations. Serum was used to analyze IGF-1 concentration. Body weights were measured on d 1, 9, 16, 23, and 30. To accompany the live animal phase, in vitro fermentations were performed using ruminal fluid cultures. Measurements included VFA concentrations and fermentative gas production for cultures containing crystalline menthol at 0, 0.003, 0.03, or 0.3% of substrate DM. Addition of menthol to the diet of steers resulted in a treatment × day interaction ( < 0.01) for concentrations of IGF-1, PUN, and plasma glucose. Cattle fed 0 and 0.003% menthol had greater serum IGF-1 concentrations on d 2 compared with steers fed 0.03% menthol. Steers fed 0% menthol had greater serum IGF-1 concentrations on d 9 compared with steers fed 0.03 and 0.3% menthol, whereas no differences were observed on d 23 or 30. Plasma glucose was similar among treatments until d 23, when steers supplemented with 0.03% menthol had lower glucose concentrations. Plasma urea nitrogen concentrations were not different among treatments; however, PUN concentrations varied by day. A linear response was detected for BW ( = 0.03), with steers consuming 0% menthol having the greatest BW and steers that consumed 0.3% menthol having the lightest BW until d 30. A menthol × day interaction was observed for daily feed deliveries ( < 0.01): cattle fed 0.3% menthol consumed less feed from d 5 through 12. Furthermore, in vitro gas production and VFA concentrations were unaffected by addition of menthol ( > 0.21). In conclusion, menthol supplementation minimally affected blood parameters associated with growth or ruminal fermentative activity.
Statistical Interpretation of Meniscograph Solderability Tests (1976)

As part of a thick-film characterization study, a solderability test-program was initiated utilizing the meniscograph. The meniscograph test measures the changes in wetting force as a function of time, and thus affords a description of the kinematics of the wetting phenomenon. Difficulty was encountered in the derivation of unique parameters which provide consistent statistical comparisons. As an alternate to selecting a time interval from the meniscograph trace as a measure of wetting rate or only qualitatively comparing traces, as some investigators have done, we have evaluated the approach of measuring the slope of the trace replotted so as to yield a straight line fit. A plot of the logarithm of a normalized wetting force versus time has generally afforded the best fit. To evaluate the analytical techniques, a large number of meniscograph tests were conducted employing copper, nickel, and Kovar substrates using both tin-lead and lead-indium solders; and rosin flux with varying activity. With the wetting rate estimated on the basis of the logarithmic line fit, the tests have consistently ranked solder systems with regard to substrate solderability and the activity of fluxes. Calculated equilibrium contact angles were found useful in interpreting the meniscograph traces.
Clonal Dissemination of Yersinia enterocolitica Strains with Various Susceptibilities to Nalidixic Acid (2003)

Ten epidemiologically related Yersinia enterocolitica clinical isolates were studied. Six isolates were nalidixic acid resistant (MIC > 512 microg/ml), with mutations in the quinolone resistance-determining region (QRDR) of the gyrA gene, suggesting clonal dissemination of a nalidixic acid-susceptible Y. enterocolitica strain which has acquired different mutations generating resistance to nalidixic acid.
Checkpointing multicomputer applications (2002)

The authors present a checkpointing scheme that is transparent, imposes overhead only during checkpoints, requires minimal message logging, and allows for quick resumption of execution from a checkpointed image. Since checkpointing multicomputer applications poses requirements different from those posed by checkpointing general distributed systems, existing distributed checkpointing schemes are inadequate for multicomputer checkpointing. The proposed checkpointing scheme makes use of special properties of multicomputer interconnection networks to satisfy this set of requirements. The proposed algorithm is efficient both when taking checkpoints and when recovering from checkpointed images.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
The impact of genistein supplementation on tendon functional properties and gene expression in estrogen deficient rats (2019)

ABSTRACT Purpose Tendinopathy risk increases with menopause. The phytoestrogen genistein prevents collagen loss during estrogen deficiency [ovariectomy (OVX)]. The influence of genistein on tendon function and extracellular matrix (ECM) regulation are not well known. We determined the impact of genistein on tendon function and examined potential mechanisms by which genistein alters tendon ECM. Materials and Methods Eight-week-old rats (n=42) were divided into three groups: intact, OVX, or OVX-genistein (6mg/kg/day) for 6-weeks. Tail fascicles were assessed with a Deben tensile stage. Achilles tendon mRNA expression was determined with digital droplet PCR. Tendon-derived fibroblasts were also treated with genistein in the presence of estrogen receptor (ER) antagonists. Results Compared to intact, stress tended to be lower in untreated OVX rats (p=0.022). Further, modulus and energy density were greater in genistein-treated rats (p&lt;0.05) compared to intact. Neither OVX nor genistein altered expression of Col1a1, Col3a1, Casp3, Casp8, Mmp1a, Mmp2, or Mmp9 (p&gt;0.05). Compared to intact, Tnmd and Esr1 expression was greater and Pcna and Timp1 expression lower in OVX rats (p&lt;0.05). Genistein treatment returned Tnmd, Pcna, and Timp1 to levels of Intact-Vehicle (p&lt;0.05), but did not alter Scx or Esr1 (p&gt;0.05). Several β-catenin/Wnt signaling related molecules were not altered by OVX or genistein (p&gt;0.05). In vitro , genistein blunted cell proliferation but not via ERs. Conclusions Our findings demonstrate that genistein improves tendon function. Genistein inhibits cell proliferation in vitro but not via ER. The effect of genistein in vivo was predominately on genes related to cell proliferation rather than collagen remodeling.
