Effects of fish oil type, lipid antioxidants and presence of rapeseed oil on oxidative flavour stability of fish oil enriched milk (2004)

Abstract As a part of our ongoing experiments on optimization of the oxidative stability of fish oils in genuine food systems, this study investigated the oxidative deterioration of fish oil enriched milk emulsions during cold storage. The experimental data showed that addition of rapeseed oil to fish oil (1:1) prior to emulsification into milk significantly protected the emulsions against oxidative deterioration. Addition of propyl gallate and a citric acid ester to the fish oil prior to emulsification also protected the fish oil enriched milk during storage. Emulsions containing a rapeseed:fish oil mixture were oxidatively stable during 11 d at 2 °C. Thus, no additional inhibitory effect of the added antioxidants was observed. The peroxide value and concentrations of five selected volatiles derived from n‐ 3 PUFA degradation in rapeseed:fish oil mixture emulsions were not significantly different from the corresponding levels in neither the emulsion containing only rapeseed oil nor the milk. It is proposed that the tocopherols in rapeseed oil may be the protective factor. Three‐way chemometric exploratory data analysis was implemented in form of a parallel factor analysis (PARAFAC). The PARAFAC model provided an overview of the obtained data with significantly enhanced interpretability, and revealed information about groupings and correlations in our data.
A Facile Strategy for the Functionalization of Boron Nitride Nanotubes with Pd Nanoparticles (2015)

A facile in situ fabrication of palladium nanoparticles decorated boron nitride nanotubes (Pd‐BNNTs) is described. The decoration of BNNTs was carried out by the self‐regulated reduction of palladium chloride (PdCl 2 ) with the aid of sodium dodecyl sulfate (SDS). During the preparation process, the surfactant SDS plays a dual role: it aids the dispersibility of BNNTs and produces the reductant of CH 3 (CH 2 ) 10 CH 2 OH. Then the CH 3 (CH 2 ) 10 CH 2 OH can reduce Pd 2+ to form Pd nanoparticles on the surface of BNNSs. The as‐prepared Pd‐BNNTs were characterized by field emission scanning electron microscopy, transmission electron microscopy, X‐ray energy dispersive spectroscopy, and Fourier transform infrared spectroscopy. The results show that the Pd nanocrystalline particles can be deposited onto the BNNTs surface via this simple route. This approach constitutes a basis for the assembly and integration of nanoscale materials onto BNNTs and puts a light on the potential application of the BNNTs in electronic, catalysis, and hydrogen storage fields.
Serotonergic regulation of canine enteric motility (measured as electrical activity) and absorption: physiologic and morphologic evidence (1988)

To explore the effect of serotonin (5-HT) on enteric electrical activity, transit and absorption, four dogs were prepared with 50 cm jejunal and ileal Vella loops. Electrodes for recording enteric electrical activity were attached to the loops and to the main small bowel. After recovery, both loops were perfused with a [14C-]PEG-glucose-electrolyte solution via the proximal stomas, while effluent was collected from the distal stomas and enteric electrical activity was monitored. Control periods were compared with periods when 5-HT was infused intravenously at a rate of 10 micrograms kg-1 min-1 for 60 min. Serotonin increased the mean +/- SEM % of jejunal and ileal pacesetter potentials with spike potentials from 33 +/- 7% and 35 +/- 9%, before infusion to 63 +/- 4% and 61 +/- 5% after infusion (P less than 0.05). Serotonin also induced distally-migrating bursts of spikes in the incontinuity small bowel. The changes were blocked by atropine, but not by ketanserin. Absorption of water, sodium and glucose from the jejunal and ileal loop and transit through the loops was not changed by 5-HT. At autopsy, all layers of the jejunum and ileum contained varicose nerve fibres with a positive immunoreaction to 5-HT, while positive nerve cell bodies were largely confined to the submucosa.
High-speed 3D shape measurement of transparent objects by sequential thermal fringe projection and image acquisition in the long-wave infrared (2023)

Recently, we have successfully tackled the challenge of measuring the 3D shape of uncooperative materials, i.e., materials with optical properties such as being glossy, transparent, absorbent, or translucent. By projecting sequential thermal fringes in the long-wave infrared (LWIR) combined with a stereo camera setup in the midwave infrared (MWIR), we were able to three-dimensionally record object shapes within one second. However, in many applications, e.g., for 100 % quality assurance, even shorter measurement times are required. To achieve camera frame rates higher than 125 fps at room temperature, Max Planck’s law of thermal emission teaches us a change in the camera spectral range from MWIR to LWIR. If irradiation and image acquisition have to run in parallel, the camera chips must therefore be protected against the radiation projected by the CO<sub>2</sub> laser at a wavelength of 10.6 µm. Appropriate filters have been available only recently. In this contribution, we present our high-speed LWIR 3D sensor. The work includes a characterization of our setup regarding its measurement accuracy and speed. The results are compared to the performance of previous thermal 3D sensors. We show 3D measurement results of static objects as well as of a dynamic measurement situation of a transparent object. Furthermore, we demonstrate that our setup enables us to extend the measurability of material classes towards objects with high thermal conductivities.
Mortality of Eggs of Stored-Product Insects Held Under Vacuum: Effects of Pressure, Temperature, and Exposure Time (2004)

Low pressure applied to a commodity creates a low-oxygen atmosphere that can be effective to control stored-product insects. Previous work determined that eggs of several species of stored-product insects were among the most tolerant life stages to low pressure. The current study was conducted to determine the mortality of eggs in response to various pressures, temperatures, and exposure times. An initial experiment determined that the sensitivity of eggs to vacuum varied with their age. Eggs of Plodia interpunctella (Hübner) were most sensitive to low pressure when they were 3 or 48 h old, whereas those of Rhyzopertha dominica (F.) were most sensitive at 12 and 120 h of age. In subsequent experiments, eggs of Cadra cautella (Walker), P. interpunctella, R. dominica, and Tribolium castaneum (Herbst) were exposed to pressures of 50, 75, 100, 200, and 300 mmHg in glass chambers at 5, 15, 22.5, 30, and 37.5 degrees C for times ranging from 12 to 168 h. Time-mortality data were subjected to probit analyses and lethal dose ratios were computed to determine differences in lethal time values among species across the 25 low pressure-temperature combinations for each species. In all four species the mortality of eggs increased with increasing exposure time and temperature. Low temperatures and high pressures were the least effective conditions for killing eggs, compared with high temperatures combined with low pressures in all species investigated. These results provide important guidelines for developing treatment schedules for disinfestation of commodities on a commercial scale.

Face recognition and clustering for home photos (2011)

In this work, we focus on clustering faces in home photos by face recognition technologies. We propose two methods to improve the approach based on a well-known algorithm, local binary patterns. The adoption of the partial matching metric improves the recognition accuracy under face pose variations, while the adoption of the Gabor filter improves the accuracy under noises and various illuminations. We evaluate our methods on two home photo sets. In both evaluations, the results show that our methods improve the performance in accuracy. Compared to baseline LBP methods, in both evaluations, the results show that our methods improve the performance in accuracy from 90.4% to 99.5% and from 94.7% to 99.6% in two home-photo data sets respectively. Even compared to Google Picasa, the number of clusters where there is only one photo (thus can not be merged with other clusters, also means not good), our methods show that the number of "single" clusters reduced by half can be achieved. Our experience also shows that GPU speedup for Gabor filter can reach 140 times, and the overall system plus clustering can thus have 10 times speedup for face recognition.
O3.02 * RADIATION-INDUCED LEUKOENCEPHALOPATHY IS A DEFINITE TYPE OF SMALL VESSEL DISEASE - NEUROPSYCHOLOGICAL AND MRI DESCRIPTION IN 40 PATIENTS (2014)

BACKGROUND: Currently, the most common and serious delayed complication of cerebral RT is radiation-induced leukoencephalopathy (RIL), roughly defined, in absence of strictly consensual criteria, by cognitive dysfunctions associated with diffuse FLAIR MRI white matter hyperintensity (HI). The objective of our study is to clearly define the RIL criteria. METHODS: Patients, addressed to our center between June 2010 and June 2012, with medical history of focal or whole brain RT who developed a persistent cognitive complain at least six months after the end of the brain RT, and presenting brain MRI FLAIR abnormalities were eligible. There was a clinical evaluation by a neurologist and a neuropsychological assessment (Edinburgh scale for lateralization, educational level, Mattis dementia rating scale (DRS) and Folsteins'MMSE, Grober and Buschke memory evaluation, forward and backward digit span, phonemic and semantic verbal fluencies, DO80). All patients were scanned by a standardized MRI protocol. White matter FLAIR lesions were evaluated with a 1 to 14 points score according to a modified Scheltens rating scale. Brain atrophy was visually assessed. Consensually defined signs of small vessels diseases (CSVD) were assessed for each patient. RESULT: Fourty patients were enrolled in our study (mostly stage 3 gliomas (27.5%)). The mean fraction dose was 2 Gy (range 1,5-3) and a mean total dose of 49 Gy (range 30-60). Most patient had gait difficulties, urinary trouble and cognitive complain. Memory difficulties were reported by 77% of patients. Neuropsychological assessment showed global and severe cognitive decline. Mattis DRS was abnormal in 75% of the patients. Forward and backward digit span were pathological in 80% patients. On brain MRI, an extensive FLAIR HI with anterior predominance was shown in 68,5% patients. Brain atrophy was present in 87% cases. T2*-weighted- MRI showed hypointensities like “black dots” probably corresponding to microbleeds or radiation induced cavernomas in 52,6% patients. We found no recent small cortical infarct. We found no correlation between FLAIR HI extension, brain atrophy, microbleeds numbers or location, perivascular spaces number, lacunes of presumed vascular origin and the cognitive compound score. We found no correlation between the delay from RT and one of the MRI lesions described above. The patients displayed a loss of executive functions responsible of severe cognitive disability and dementia as previously described in patients with CSVD. Our study give strong clinical and MRI arguments to consider that the RIL is a delayed progressive CSVD, with characteristic evolution and distribution pattern namely implicating distal brain superficial perforating arterioles that serve dorsolateral loops of white matter in the corona radiata and sparing basal ganglia perforating arterioles that spring from the cerebral medial artery.
Functional Studies of Maturing Myeloid Cells During Ex Vivo Expansion for Treatment of Aplasia: Feasibility of Ex Vivo Expansion from Cryopreserved Bone Marrow Cell Samples (1998)

Ex vivo expanded CD34+ progenitor cells from fresh or cryopreserved primate bone marrow, induced to granulocytic differentiation with growth factors, were investigated to determine whether myeloid cells produced in liquid cultures have the normal biologic functions needed for the treatment of patients with neutropenia following high-dose chemotherapy or therapeutic or accidental radiation exposure. Human and simian (baboons or macaques) CD34+ cells were cultured with granulocyte-colony stimulating factor (G-CSF), stem cell factor (SCF), interleukin-1 (IL-1), IL-3, and IL-6, and assessed at 14 days of culture for their capacity to respond to different functional tests. Immunostaining revealed that human ex vivo expanded cells contained myeloperoxydase (MPO, 82% +/- 8%) and lactoferrin (LF, 30% +/- 6%) in their granules. Maturation of cultured cells was associated with stimulated chemotactic responsiveness and respiratory burst activity (superoxide anion and hydrogen peroxide production) in expansions from human, baboon, and macaque CD34+ progenitor cells. Mature cells obtained from ex vivo expansion of selected cryopreserved human bone marrow CD34+ cells presented reduced but significant functional activities (chemotactic responsiveness and hydrogen peroxide production) when compared with human peripheral blood neutrophils. The validation of nonhuman primate ex vivo expansion systems may permit their use as models of irradiation. The feasibility of ex vivo expansion from cryopreserved bone marrow cell samples may offer considerable opportunity for banking bone marrow for autologous transfusion.
A comparison of Australian and European Union research performance profiles (2009)

"Governments worldwide face the challenge of how best to prioritise their international science and innovation (S&amp;I) cooperation activities. This involves balancing the intrinsic benefits that may arise from international S&amp;I cooperation with extrinsic considerations – diplomacy, trade, national security etc. The interplay of these intrinsic and extrinsic considerations means that complex and often ambiguous tradeoffs need to be addressed by policymakers. In some cases international S&amp;I cooperation priorities will reflect extrinsic diplomatic and geopolitical goals. In other cases the objectives will relate more closely to balancing the costs, risks and benefits of particular bilateral and multilateral S&amp;I cooperation opportunities. Given the limited financial resources available to support international S&amp;I cooperation it is useful for policymakers to have access to appropriate decision-support tools and&#13;\ninformation. This should help to avoid wasteful resource allocations caused by a lack of access to relevant information.This paper seeks to contribute to the evolving policy framework in this area by considering ways of characterising and mapping international imbalances in research performance." - page 2
Plasmodium falciparum: modulation by calcium antagonists of resistance to chloroquine, desethylchloroquine, quinine, and quinidine in vitro (1990)

Intrinsic interactions of calcium antagonists (broadly defined) and quinoline-containing antimalarial drugs were evaluated against chloroquine-sensitive and chloroquine-resistant clones of Plasmodium falciparum in vitro. Verapamil, D-600 (methoxyverapamil), Ro 11-2933/001 (tiapamil analogue), chlorpromazine, SKF 21133-A (chlorpromazine analogue), and diltiazem each potentiated the efficacy of the quinoline-containing antimalarials chloroquine, desethylchloroquine, and quinine with a chloroquine-resistant clone of P. falciparum, but did not affect the response of the quinoline-susceptible clone. Similar concentrations of either chlorpromazine or Ro 11-2933/001 lowered the IC50 of the resistant clone to approximately the same level as that observed for the sensitive clone for each of the quinolines tested. This reversal of resistance by many of the same calcium antagonists underscores the similarities in one mechanism of multi-drug resistance in neoplastic cells and quinoline-resistance in P. falciparum.
Upper airway reflexes in newborns with respiratory distress syndrome. (1985)

In 16 newborns with respiratory distress syndrome (RDS) not artificially ventilated, oesophageal pressure was recorded with an electromanometer and the reactions to mechanical stimulation of the upper airways by means of a nylon fibre were investigated. The results were compared with the values obtained in 16 newborns without cardiorespiratory disturbances. The reactions were evoked by mechanical stimulation of the airways. Mechanical stimulation of the nasal mucosa produced expulsive reactions only in 45% of cases in newborns with RDS as compared with 95% in healthy newborns (p less than 0.001). Stimulation of the oropharyngeal and laryngeal regions elicited expulsive reactions in 48% of cases in newborns with RDS, but 74% in healthy newborns (p less than 0.001). In other cases, inhibition of breathing or apnoea was the most common reaction. The expulsive component of responses such as sneezing, expiratory reaction and crying was weaker in newborns with RDS than in control infants. The inspiratory component of sneezing and coughing, on the contrary, was stronger in newborns with RDS. These results indicate that active elimination of irritants from the airways is reduced in newborns with RDS.

Two-stage reverse osmosis : optimal elementconfiguration and flux distribution, energy savings; 2-stage RO : optimal element configuration and fluxdistribution, energy savings; Optimal element configuration and flux distribution,energy savings (2017)

In a two-stage reverse osmosis (RO) system of finite
size, there are two degrees of freedom not present in a
single-stage RO system: distribution of RO elements between the two
stages (system design), and feed pressures (system operation). In
this study, we investigate the optimal system design and operation
of a two-stage RO system with a mass-balance model and establish a
lower bound for the energy savings achieved by the optimized
two-stage system compared to a single-stage system. A two-stage RO
system may consume more or less energy than a single-stage RO
system of the same size and freshwater productivity, depending on
the first-stage feed pressure and second-stage feed pressure. To
minimize energy consumption, feed pressures should be chosen to
minimize spatial variance in flux. The optimal element
configuration places at least half the elements in the first stage;
the exact configuration depends on feed salinity, recovery ratio,
and membrane permeability. The greatest energy savings are achieved
with a two-stage RO system that has both optimal element
configuration and feed pressures. More energy can be saved by
adding a stage when the thermodynamic least work of separation is
larger. For a given feed salinity, energy savings from adding a
second stage grow as recovery ratio increases. Brackish water feeds
must be taken to high recovery ratios to achieve substantial energy
savings; comparable savings can be achieved at lower recovery
ratios for higher salinity feeds. We find that significant energy
can be saved with the simplest two-stage RO design, at a system
flux similar to today's RO plants and accounting for the effects of
concentration polarization.
6$\,\times\,$128-Gb/s Nyquist-WDM PDM-16QAM Generation and Transmission Over 1200-km SMF-28 With SE of 7.47 b/s/Hz (2012)

The Nyquist wavelength-division multiplexing technique enable a solution to achieve high spectral efficiency in long-haul transmission system. Compare to polarization division multiplexing quadrature-phase-shift-keying, even high-level modulation scheme such as polarization division multiplexing 16-quadrature-amplitude-modulation is much more sensitive to intra-channel noise and inter-channel linear crosstalk caused by Nyquist wavelength-division multiplexing. We experimentally demonstrated the generation and transmission of the 6 × 128-Gb/s Nyquist wavelength-division multiplexing sixteen quadrature amplitude modulation signal over 1200-km single-mode fiber (SMF)-28 with Erbium-doped fiber amplifier only amplification with a net SE of 7.47 b/s/Hz, which is so far, to our knowledge, the highest SE for the signal with the bit rate above 100-Gb/s using the polarization-division multiplexing 16-quadrature-amplitude-modulation format. This experiment was successfully enabled by digital-signal-processing (DSP) pre-equalization of transmitter-side impairments and DSP post-equalization of the channel and receiver-side impairments. Nyquist-band is considered in the pre- equalization to enhance the tolerance of the polarization-division multiplexing 16-quadrature-amplitude-modulation to the aggressive spectral shaping. The bit error rate for each of the 6 channels is smaller than the limitation of the forward-error-correction limit of 3.8 ×10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> after 1200-km SMF-28 transmission.
Advancing silicon photonics by germanium ion implantation into silicon (2018)

We review our recent developments of the trimming techniques for correcting the operating point of ring resonator and Mach-Zehnder Interferometers (MZIs). This technology has been employed to fine-tune the effective index of waveguides, and therefore the operating point of photonic devices, enabling permanent correction of optical phase error induced by fabrication variations. Large resonance wavelength shift of ring resonators was demonstrated, and the shift can be tuned via changing the laser power used for annealing. A higher accuracy trimming technique with a scanning laser was also demonstrated to fine-tune the operating point of integrated MZIs. The effective index change of the optical mode is up to 0.19 in our measurements, which is approximately an order of magnitude improvement compared to previous work, whilst retaining similar excess optical loss.
