Colloidal nanocrystal-based light-emitting diodes fabricated on plastic toward flexible quantum dot optoelectronics (2009)

We report the demonstration of mechanically flexible quantum dot light emitting diodes (QD-LEDs) of all three primary colors (red, green, and blue). The QD-LEDs have been fabricated over poly(ethylene-terephthalate) substrates and exhibited high brightness, saturated colors, and pronounced flexibility with a critical bending radius of ∼5 mm. The efficiencies of the flexible QD-LEDs are comparable with the devices fabricated on rigid substrates, suggesting the intrinsic flexibility of quantum dot-based optoelectronic devices.
Influence of hydration state on hormonal responses to exercise in dogs. (1991)

The purpose of these studies was to determine how plasma levels of arginine vasopressin (pAVP) are related to workload, plasma osmolality (pOsm), blood volume (BV) and plasma angiotensin II (pAII) in exercising dogs. Measurements were made in dogs running on a treadmill at 7.5 km. hr-1 at slopes of 0, 10% and 20% when they were hydrated ad lib and when they had been deprived of drinking water and also in dogs running on a 20% slope after an IV infusion of hypertonic NaCl. Dehydration increased pOsm by 6.6% and reduced BV by 10% in resting dogs. In dehydrated animals, pAVP, pAII and pOsm were elevated above hydrated levels at rest and during exercise at all three workloads. In hydrated dogs, pOsm rose during exercise at 10% and 20% slopes but pAVP rose above resting levels only at the highest workload and pAII was not affected by exercise. In dehydrated dogs, pOsm and pAVP rose during exercise at 10% and 20% slopes and pAII was elevated at the 20% slope. BV decreased during exercise at the highest workload in both hydrated and dehydrated animals. After hypertonic NaCl, pAVP rose during exercise but pOsm and pAII did not. The results suggest that both osmotic and nonosmotic factors contribute to the release of AVP in exercising dogs and that exercise leads to a leftward shift in the relationship of pAVP to pOSM which could be a result of reduced blood volume.
Cardiac stem cells (2002)

Augmentation of myocardial performance in experimental models of therapeutic infarction and heart failure has been achieved by the transplantation of exogenous cells into damaged myocardium, a procedure known as cellular cardiomyoplasty (CCM). Historically, a wide range of cell types have been used for CCM, including rat and human fetal ventricular myocytes, but the availability of human fetal donor cells for clinical purposes is limited. The quest for suitable alternative donor cells has prompted research into the use of both embryonic stem (ES) cells and adult somatic stem cells, but the optimal choice of donor cell source is not yet known. Recently, there has been a growing body of evidence that multipotent somatic stem cells in adult bone marrow exhibit tremendous functional plasticity and can reprogramme in a new environmental tissue niche to give rise to cell lineages specific for the new organ site. This phenomenon has made a huge impact on myocardial biology and has captured the imagination of scientists who have recently discovered that multipotent adult bone marrow haematopoeitic stem cells and mesenchymal stem cells can repopulate infarcted rodent myocardium and differentiate into both cardiomyocytes and new blood vessels. These data, coupled with the identification of a putative primitive cardiac stem cell population in the adult human heart, may pave the way for novel therapeutic modalities for enhancing myocardial performance and treating end-stage cardiac disease.
Unsupervised Discovery of Object Landmarks as Structural Representations (2018)

Deep neural networks can model images with rich latent representations, but they cannot naturally conceptualize structures of object categories in a human-perceptible way. This paper addresses the problem of learning object structures in an image modeling process without supervision. We propose an autoencoding formulation to discover landmarks as explicit structural representations. The encoding module outputs landmark coordinates, whose validity is ensured by constraints that reflect the necessary properties for landmarks. The decoding module takes the landmarks as a part of the learnable input representations in an end-to-end differentiable framework. Our discovered landmarks are semantically meaningful and more predictive of manually annotated landmarks than those discovered by previous methods. The coordinates of our landmarks are also complementary features to pretrained deep-neural-network representations in recognizing visual attributes. In addition, the proposed method naturally creates an unsupervised, perceptible interface to manipulate object shapes and decode images with controllable structures.

Portable forced oscillation device for point-of-care pulmonary function testing (2016)

The forced oscillation technique (FOT) provides a simple and accurate approach for pulmonary function testing. However, most current devices are large and high cost, hence the test remains sparingly used. To address this problem, we verified the feasibility of a smart and portable forced oscillation device based on a small subwoofer and ultrasonic sensor that is targeted at point-of-care pulmonary function testing. In this paper, we first develop and optimize the signal processing algorithm for impedance estimation. Then we characterize the signal quality of programmable oscillatory waveforms with varying frequency, amplitude and duration. Finally, we evaluate the performance of the device against both mechanical models and human subjects. The results show that the coherence function is above 0.9 for all frequencies and the measurement error is less than 10%. The device yields good repeatability and satisfies the clinical diagnostic requirements.
COMPARATIVE STUDY ON THE UTILISATION OF ACTIVE MATERIAL IN THE CAST AND EXPANDED LEAD ALLOY NEGATIVE GRID (1999)

This paper compares the performance of negative plates made from cast and expanded Pb-Ca-Sn grid alloy at different rates of discharge (current density). It has been found that at very low rate of discharge the active material utilisation of expanded grid is more whereas at high discharge rates the active material utilisation is more in the case of cast grid.

Structural and functional role of lipids in yeast and mycelial forms ofCandida albicans (1994)

The levels of total lipids, sterols and phospholipids were found to be significantly higher in the mycelial form (log phase) of Candida albicans than in the yeast form. Increased phospholipid levels in the mycelial form were due to higher levels of phosphatidylcholine, phosphatidylserine and phosphatidylinositol. Analyses of fatty acid composition also revealed higher levels of myristic acid (40%) in the yeast form, resulting in higher levels of saturated lipids than in the mycelial form. The changes in the lipid composition were also manifested in altered thermotropic phase behavior as gel-to-liquid crystalline phase transitions were observed at 36 and 27 degrees C for the lipids of the yeast and mycelial forms, respectively. These changes coincided with higher uptake rate, i.e., Km and Vmax values, for the transport of L-proline and with a higher sensitivity of the mycelial form against antifungal drugs.

SIP security issues: the SIP authentication procedure and its processing load (2002)

Session Initiation Protocol (SIP) is currently receiving much attention and seems to be the most promising candidate as a signaling protocol for the current and future IP telephony services, also becoming a real competitor to the plain old telephone service. For the realization of such a scenario, there is an obvious need to provide a certain level of quality and security, comparable to that provided by the traditional telephone systems. While the problem of QoS mostly refers to the network layer, the problem of security is strictly related to the signaling mechanisms and the service provisioning model. For this reason, at present, a very hot topic in the SIP and IP telephony standardization track is security support. In this work, the security model used by SIP is described, and the different open issues are highlighted. We focus, in particular, on the problem of authentication providing a short tutorial on the solution under standardization. The architecture of a possible commercial IP telephony service including user authentication is also described. Finally, we focus on performance issues. By means of a real testbed implementation, we provide an experimental performance analysis of the SIP security mechanisms, based on our open source Java implementation of a SIP proxy server. The performance of the server has been compared with and without security support, under various scenarios.
Optical disk readout analysis using an extended point-spread function (1999)

troduction The scalar diffraction theory represented by the Hopkins’ method has been widely used for simulating the readout signals from optical pickups. This method is based on the partially coherence theory, and was well improved by previous works, for example the classification into the two types of scanning microscopes,2&lt; extension for MO pickups, and so on. Furthermore, various super-resolution techniques and the crosstalk reduction technique were analyzed theoretically by using this scalar diffraction theory. On the use of this theory, the light amplitude distribution on the exit pupil of the objective lens or the modulation transfer function (MTF) is usually employed for the explanation of the functions of optics. Meanwhile, the method we present here is based on the work by Velzel. His method is basically an approximation of the scalar theory and concentrates on the point spread function (PSF) of the illumination optics in the pickup. And it provides a simple and practical way for computations and understanding of the readout process. For example, Kubota presented in his study the influences of wave front aberrations on the readout characteristics by using jitter calculations, in which the readout signal was calculated as a convolution of the pits on the disk and the PSF. In this paper, we present a method using an extended point spread function (EPSF) that can be applied for the case when the detector has an arbitrary shape and information pits are recorded on a groove. After that, two examples, differential phase detection (DPD) method and jitter analysis of the readout signal from pits on a groove, will be shown. Although our method is also an approximation, physical and intuitive considerations will be acquired even under such complex cases.
Algorithm 754: Fortran subroutines for approximate solution of dense quadratic assignment problems using GRASP (1996)

In the NP-complete quadratic assignment problem (QAP), n facilities are to be assigned to n sites at minimum cost. The contribution of assigning facility i to site k and facility j to site l to the total cost is f ij d kl , where f ij is the flow between facilities i and j , and d kl is the distance between sites k and l . Only very small ( n ≤20) instances of the QAP have been solved exactly, and heuristics are therefore used to produce approximate solutions. This article describes a set of Fortran subroutines to find approximate solutions to dense quadratic assignment problems, having at least one symmetric flow or distance matrix. A greedy, randomized, adaptive search procedure (GRASP) is used to produce the solutions. The design and implementation of the code are described in detail, and extensive computational experiments are reported, illustrating solution quality as a function of running time.
Compensator Design and Stability Assessment for Fast Voltage Loops of Power Factor Correction Rectifiers (2007)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This paper introduces a new method for stability analysis and design of fast voltage-loop compensators in rectifiers with power factor correction (PFC). The method has few constraints and can be used with various implementations of the fast voltage loop. It is based on utilization of circle criterion, which unifies frequency domain and nonlinear system analysis. A step-by-step procedure of stability assessment and compensator design is described and demonstrated on two controller implementations. In the first system, the voltage-loop dynamic response of an experimental 200-W digitally-controlled boost-based PFC is improved with a self-tuning comb filter. In the second implementation, it is shown how the circle criterion can be used to design a fast voltage loop for controllers with regulation band, i.e., "dead-zone," element for ripple elimination. </para>
Comparison of adjuvant chemoradiation to perioperative chemotherapy for the treatment of resected gastric and gastroesophageal junction adenocarincoma. (2015)

139 Background: There are several accepted peri-operative treatment modalities for resected gastric (GC) and gastroesophageal junction (GEJ) adenocarcinoma. In 2008, peri-operative chemotherapy (CT) using the MAGIC protocol was adopted as the preferred approach over adjuvant chemoradiation with the MacDonald protocol (cXRT) in British Columbia. An era to era comparison was performed to determine if there were differences in outcomes. Methods: Data from pharmacy records of patients (pts) referred to 1 of 5 cancer treatment centres in BC were analyzed from Jan 2001-July 2010. Pts that underwent curative resection for GC or GEJ were included. The cXRT cohort was defined as those treated from Jan 2001-Dec 2007, prior to the introduction of CT. The CT cohort included those treated from Jan 2008-July 2010. Descriptive statistics were used to compare the groups. Survival analysis was performed using Kaplan Meier methods. Results: Table 1 summarizes the patient characteristics. In the CT arm, there were more males, fewer pts with a LN ratio &gt;0.2, and shorter median follow-up. 92.1% completed pre-operative chemotherapy and 44.7% completed post-operative chemotherapy whereas 73.3% of pts completed cXRT (p&lt;0.05). Median survival was 37.5 and 36.9 months in the CT and cXRT arms, respectively. Conclusions: Delivery of CT was consistent with the MAGIC trial whereas more patients completed cXRT than in the MacDonald trial (73.3% vs. 64%). Outcomes of CT compared to cXRT appear to be similar in this comparative analysis with similar relapse and survival rates. Pre-operative CT results in fewer pts with a LN ratio &gt; 0.2. Either modality can be considered in the peri-operative management of GC or GEJ adenocarcinoma. [Table: see text]
Defective Candidacidal Activity of Alveolar Macrophages and Peripheral Blood Monocytes from Patients with Chronic Obstructive Pulmonary Disease (1991)

We investigated the in vitro candidacidal activity of alveolar macrophages (AM) and peripheral blood monocytes (PBM) from normal subjects or from patients with chronic obstructive pulmonary disease (COPD) displaying defective skin test delayed-type hypersensitivity (DTH) reactivity to seven antigens including Candida albicans. The results showed that cells from patients with COPD were significantly less effective than cells from control subjects in the killing of C. albicans. To explore whether the observed functional impairment could be reversed, interferon-gamma (IFN-gamma) was added to AM and PBM from patients with COPD, alone or in the presence of lipopolysaccharide (LPS) as a suboptimal stimulus. The cells were cultured for 24 h and then assayed for anti-Candida activity. After IFN-gamma treatment, the fungicidal activity of cells from patients with COPD was comparable to that of unstimulated AM or PBM from healthy donors. Treatment with IFN-gamma plus LPS resulted in a further enhancement in the killing of C. albicans. To gain more insight into the mechanisms involved in the modulation of killing, we evaluated the possible stimulating activity of IFN-gamma plus LPS treatment on the secretion of tumor necrosis factor (TNF) and interleukin-1 (IL-1), two cytokines produced by activated macrophages and capable of stimulating natural effectors. The results showed that IFN-gamma plus LPS can indeed stimulate TNF and IL-1 secretion by AM and PBM from patients with COPD. Therefore, a precise role can reasonably be ascribed to these soluble factors in the observed augmentation of candidacidal activity as ascertained by treatment with IFN-gamma plus LPS.
Vehicle tracking across nonoverlapping cameras using joint kinematic and appearance features (2011)

We describe a vehicle tracking algorithm using input from a network of nonoverlapping cameras. Our algorithm is based on a novel statistical formulation that uses joint kinematic and image appearance information to link local tracks of the same vehicles into global tracks with longer persistence. The algorithm can handle significant spatial separation between the cameras and is robust to challenging tracking conditions such as high traffic density, or complex road infrastructure. In these cases, traditional tracking formulations based on MHT, or JPDA algorithms, may fail to produce track associations across cameras due to the weak predictive models employed. We make several new contributions in this paper. Firstly, we model kinematic constraints between any two local tracks using road networks and transit time distributions. The transit time distributions are calculated dynamically as convolutions of normalized transit time distributions that are learned and adapted separately for individual roads. Secondly, we present a complete statistical tracker formulation, which combines kinematic and appearance likelihoods within a multi-hypothesis framework. We have extensively evaluated the algorithm proposed using a network of ground-based cameras with narrow field of view. The tracking results obtained on a large ground-truthed dataset demonstrate the effectiveness of the algorithm proposed.
Suppression of halide migration and immobile ionic surface passivation for blue perovskite light-emitting diodes (2022)

The introduction of an immobile passivation material leads to the suppression of the deeper defect states of Cl-mixed perovskite nanocrystals, while the inevitable halide migration is hampered, resulting in high efficiency and spectral stability of blue PeLEDs.
The Balance between Orthodontic Force and Radiation in the Jawbone: Microstructural, Histological, and Molecular Study in a Rat Model (2021)

Irradiation of facial bones is associated with a lifelong risk of osteonecrosis. In a rat model, maxillae were exposed to a single 5 Gy dose of external beam radiation and orthodontic force was applied for 2 weeks on the first maxillary molar; control rats were treated identically without radiation. Tooth movement in irradiated jaws was 30% less than in controls, representing radiation-related damage. Micro-CT, histological, and molecular outcomes of orthodontic tooth movement were studied. Microstructurally, bone parameters (trabecular thickness, bone volume fraction, bone mineral density) were significantly affected by orthodontic force but not by radiation. Histological parameters were influenced only by orthodontic force, especially by an increase in osteoclasts. A molecular study revealed a differential distribution of cells expressing pre-osteoclast markers (RANK+-majority, CD11b+, CD14+-minority), with changes being influenced by orthodontic force (increased CD11b+ and CD14+ cells) and also by radiation (decreased RANK+ cells). The activation status of osteoclasts (TRAP staining) showed an orthodontic-force-related increase, which probably could not fully compensate for the radiation-associated impairment. The overall balance showed that orthodontic force had elicited a substantial microstructural, histological, and functional normalization process in irradiated maxillae but a radiation-induced impact was still conspicuous. Additional studies are needed to validate these findings.
Birefringence compensation in double-core optical waveguides (2002)

A new concept for birefringence compensation in planar optical waveguides applying a double-core structure is introduced. It is demonstrated on waveguides fabricated in silicon oxynitride technology for applications in optical telecommunication.
