Effect of strain and temperature on anomalously large interdiffusion in InAsP/InP heterostructures (1997)

We present evidence for anomalously large, strain-dependent interdiffusion in InAs1−xPx layers grown on InP(001) substrates by organometallic vapor phase epitaxy at 620 °C. Specifically, there are strong indications for the existence of a “critical strain:” if the strain is ∼1.9% or more, much P–As mixing occurs, but for smaller strain the mixing is greatly decreased. The interdiffusion is also highly sensitive to temperature. A set of samples grown at 580 °C exhibits a factor of ∼2 decrease in P–As mixing compared to a set grown at 620 °C.

Prostaglandin F2α Induced Luteolysis of Aging Corpora Lutea in Pigs (1999)

Prostaglandins primarily of uterine origin play an important role in parturition. Hysterectomy of nongravid pigs early in the luteal phase maintains luteal function until about day 150, whereas the duration of normal pregnancy is about 114 days. Precisely timed peak release of relaxin and coincident decrease in progesterone secretion occur in unmated hysterectomized gilts similar to that found a few hours preceding parturition. It is hypothesized that prostaglandin F 2 α (PGF 2 α) in hysterectomized pigs mimics abrupt changes in ovarian and pituitary hormone secretion seen preceding normal parturition and in early lactation. Unmated Yorkshire gilts were hysterectomized on days 6–8 of a normal estrous cycle, and at 1200 hours on day 113, they were given an i.m. injection of 30 mg PGF 2 α -THAM salt or phosphate buffer saline (PBS). None of these gilts expressed behavioral estrus immediately after PGF 2 α or vehicle treatment. On day 113, PGF 2 α increased peak relaxin (60 ng/ml) compared with controls (34 ng/ml; P&lt;.01), whereas progesterone decreased abruptly (4 vs. 16 ng/ml in PGF 2 α and PBS; P&lt;.01). The prolactin (PRL) remained at &lt;5 ng/ml from day 98 to 120 in controls but peaked at 33 ng/ml immediately after PGF 2 α treatment on day 113, and then decreased to levels similar to controls on day 120. Sequential bleeding revealed an acute growth hormone (GH) release (4.5 ng/ml) immediately after PGF 2 α injection and return to basal levels (&lt;.6 ng/ml) on days 114 to 120. The PGF 2 α induced abrupt shifts in progesterone, relaxin, PRL, and GH secretion in hysterectomized gilts that mimic hormone changes seen in late pregnancy, parturition, and early lactation. These findings provide new insight into the role of PGF 2 α in abruptly altering hormone secretion by aging corpora lutea and pituitary gland even in the absence of the conceptuses or uterus in the pig.
Atomic oxygen interactions with protected organic materials on the Long Duration Exposure Facility (LDEF) (1995)

The Long Duration Exposure Facility (LDEF) has provided an excellent opportunity to understand the nature of directed atomic oxygen interactions with protected polymers and composites. Although there were relatively few samples of materials with protective coatings on their external surfaces on LDEF which were exposed to a high atomic oxygen fluence, analysis of such samples has enabled an examination of the shape of atomic oxygen undercut cavities at defect sites in the protective coatings. Samples of front-surface aluminized (Kapton) polyimide were inspected by scanning electron microscopy to identify and measure crack defects in the aluminum protective coatings. After chemical removal of the aluminum coating, measurements were also made of the width of the oxidized undercut cavities below the crack defects. The LDEF flight undercut cavity geometries were then compared with Monte Carlo computational model undercut cavity predictions. The comparison of the LDEF results and computational modeling indicates agreement in specific undercut cavity geometries for atomic oxygen reaction probabilities dependent upon the 0.68 to 3.0 power of the energy. However, no single energy dependency was adequate to replicate flight results over a variety of aluminum crack widths.
Expression level of integrin α5 on tumour cells affects the rate of metastasis to the kidney (2003)

Tumour metastasis is known clinically to have organ specificity. We hypothesised that integrins might be involved in determining the organ specificity of tumour metastasis. Here, we report the results of spontaneous metastasis tested in nude mice that were inoculated with Chinese hamster ovary (CHO) cells expressing integrin alpha 5 beta 1 at various levels. The growth of the primary tumour inversely correlated with the alpha 5 expression level on CHO cells, which is consistent with a previous report (Schreiner et al, 1991). The rates of pulmonary, lymph node, and adrenal metastases that developed in nude mice were not related to changes of the alpha 5 expression level on CHO cells. Kidney metastasis developed in 40% of nude mice inoculated with alpha 5B2 cells (CHO cells overexpressing alpha 5) and in 20% of mice with CHO-K1 cells (CHO cells expressing native alpha 5), whereas inoculation with CHO-B2 cells (alpha 5-defective mutants) and alpha 5CHO cells with the highest expression of alpha 5 did not lead to development of kidney metastasis. Furthermore, alpha 5CHO, which shows the slowest growth of these cell types, did not lead to primary tumours in nude mice. These findings suggest that there is an appropriate level of alpha 5 expression on tumour cells that leads to metastasis. Microscopic observations revealed that micrometastasis in the kidney was formed in glomeruli. An adhesion assay using frozen sections of the kidney demonstrated that alpha 5B2 cells, but not CHO-B2 cells, effectively adhered to glomeruli. Kidney metastasis in vivo and the adhesion of alpha 5B2 to glomeruli shown ex vivo were significantly suppressed by the administration of GRGDS peptide. Finally, we conclude that the interaction of alpha 5 beta 1 on tumour cells with fibronectin in kidney glomeruli is involved in kidney metastasis and that the tumour has appropriate levels of integrins crucial for metastasis.
Wound Complications from Surgery in Pregnancy-Associated Breast Cancer (PABC)1 (2010)

in our series, we had few postoperative complications and no milk fistulae for those patients undergoing surgery for PABC. When compared to those who had mastectomy for PABC, women who underwent breast conserving therapy did not appear to have increased frequency of surgical complications.

Exploiting the Physical Environment for Securing the Internet of Things (2015)

Using the randomness provided by the physical environment to build security solutions has received much attention recently. In particular, the shared entropy provided by measuring ambient audio, luminosity modalities or electromagnetic emanations has been used to build location-based, proximity-based, or context-based security mechanisms. The majority of those protocols is based on a standard model consisting channel probing, quantization, information reconciliation, privacy amplification, and key verification. The main problem for almost all approaches is the limited understanding of the security that is provided. For example, security analyses often only address single components and not the entire system or are based on broad abstractions of the physical source of randomness. Further, a big open question is the feasibility of such systems for low-resource platforms. Our first contribution is a detailed, optimized realization of a key establishment system. We demonstrate the feasibility of deriving a shared secret from correlated quantities on resource-constrained devices with tight power budget. Our system was realized on the popular ARM Cortex-M3 processor that reports detailed resource requirements. The second major contribution is a summary and abstraction of previous works together with a rigorous security analysis. We substantiate our investigation by presenting practical attack results.
A hybrid nanoparticle matrix for mass spectrometry (2013)

We demonstrate hybrid inorganic–organic nanoparticles —based on silicon dioxide and 9-aminoacridine— which can enhance mass spectrometric analysis and imaging in the negative-ion mode. The nanoparticles bind to the surface of cells while still in the liquid phase, which is followed by a controlled release of the organic matrix molecules triggered by alkaline ammonia vapours delivered to the specimen in a closed chamber. First, the method was optimized and tested using standard compounds as analytes. Second, the spatial resolution was verified using a natural fibre (diameter ∼20 μm). Third, the method was used in the imaging of molecules present in the outer layer of large algal cells (Closterium acerosum). An important advantage of this method is that nanoparticles loaded with organic matrix can be applied to the biological cells as aqueous suspensions; hence, the release and spreading of metabolites can be limited during sample preparation for MALDI-MS. In addition, since this method does not involve spraying, exposure of experimenters to toxic aerosols is decreased.
Systematic review of molecular mechanism of action of negative-pressure wound therapy (2014)

Cytokine and growth factor expression profiles under NPWT suggest that promotion of wound healing occurs by modulation of cytokines to an anti-inflammatory profile, and mechanoreceptor and chemoreceptor-mediated cell signalling, culminating in angiogenesis, extracellular matrix remodelling and deposition of granulation tissue. This provides a molecular basis for understanding NPWT.
Replicative Activity of Lung Type 2 Cells Following Lung X Irradiation (1987)

We investigated the replicative activity of type 2 cells in the lungs of mice at various times from 3 to 22 weeks after 18 Gy of X rays to the thorax. No significant changes were found until 11 weeks after thoracic X irradiation. Thereafter the replicative index of type 2 cells was significantly elevated, rising four to sixfold above that of control, sham-irradiated mice. During the period when the replicative activity of type 2 cells was elevated, the breathing frequency increased and there was histologic evidence of the presence of radiation pneumonitis. The magnitude of each of these indices of pneumonitis correlated significantly with the type 2 cell replicative index, suggesting that type 2 cell replication is related to pneumonitis in extent as well as in chronology. How these changes relate to the pathogenesis of radiation pneumonitis is unclear.
Unsupervised Domain Adaptation of Contextual Embeddings for Low-Resource\n Duplicate Question Detection (2019)

Answering questions is a primary goal of many conversational systems or\nsearch products. While most current systems have focused on answering questions\nagainst structured databases or curated knowledge graphs, on-line community\nforums or frequently asked questions (FAQ) lists offer an alternative source of\ninformation for question answering systems. Automatic duplicate question\ndetection (DQD) is the key technology need for question answering systems to\nutilize existing online forums like StackExchange. Existing annotations of\nduplicate questions in such forums are community-driven, making them sparse or\neven completely missing for many domains. Therefore, it is important to\ntransfer knowledge from related domains and tasks. Recently, contextual\nembedding models such as BERT have been outperforming many baselines by\ntransferring self-supervised information to downstream tasks. In this paper, we\napply BERT to DQD and advance it by unsupervised adaptation to StackExchange\ndomains using self-supervised learning. We show the effectiveness of this\nadaptation for low-resource settings, where little or no training data is\navailable from the target domain. Our analysis reveals that unsupervised BERT\ndomain adaptation on even small amounts of data boosts the performance of BERT.\n
Warfarin management in patients on continuous anticoagulation therapy undergoing total knee replacement (2011)

We evaluated the safety and efficacy of total knee replacement in patients receiving continuous warfarin therapy. We identified 24 consecutive patients receiving long-term warfarin therapy who underwent total knee replacement between 2006 and 2008 and compared them with a group of age- and gender-matched patients not on long-term anticoagulation. Primary observations were changes in haemoglobin, transfusion rates and complications. Secondary observations were fluctuations in the international normalised ratio (INR) and post-operative range of movement. There was no significant difference between the two groups in pre- or post-operative haemoglobin, incidence of transfusion or incidence of post-operative complications. There were no surgical delays due to a high INR level. The mean change in INR during the peri-operative phase was minimal (mean 0.4; SD 0.7). There was no significant difference in the range of movement between the two groups after day two post-operatively. Current American College of Chest Physicians guidelines recommend bridging therapy for high-risk patients receiving oral anticoagulation and undergoing major orthopaedic procedures. We have shown that a safe alternative is to continue the steady-state warfarin peri-operatively in patients on long-term anticoagulation requiring total knee replacement.
Cardiac disease in the antiphospholipid syndrome: recommendations for treatment. Committee consensus report (2003)

The Committee reviewed cardiac involvement in the antiphospholipid antibody syndrome. The Committee's recommendations are: Valve abnormalities: anticoagulation is recommended for symptomatic patients with valvulopathy. Prophylactic antiplatelet therapy may be appropriate for asymptomatic patients (recommended by 13/17 experts in an independent review). Committee members disagreed whether corticosteroid therapy is helpful, but agree that distinguishing among presumptive valvulitis (valve thickening on echocardiogram), valve deformity and vegetations is important, as treatment implications may differ. Occlusive arterial disease (angina, myocardial infarction): the Committee recommends aggressive treatment of all risk factors for atherosclerosis (hypertension, hypercholesterolaemia, smoking) and liberal use of folic acid, B vitamins and cholesterol-lowering drugs (preferably statins). Hydroxychloroquine for cardiac protection in APS patients may be considered. The Committee also recommends warfarin anticoagulation for those who have suffered thrombosis in the absence of atherosclerosis, but recognizes that developing data may support the use of antiplatelet agents instead. Intracardiac thrombi: the Committee recommends intensive warfarin anticoagulation, and consultation with cardiac surgeons when appropriate. Ventricular dysfunction: the Committee has no recommendations on this aspect of cardiac disease. Pulmonary hypertension: the Committee recommends intensive anticoagulation with warfarin and clinical trials of bosentan, epoprostenol and other new agents.
Analytical Studies on Application of Doubly-fed Rotary Frequency Converter in Power Systems (1999)

Doubly-fed (adjustable-speed) pumped storage generating systems of large capacity have been installed in power systems with recent progress of power electronics technologies as its setting. Many papers have been published in which the enhancement of power system stability by application of doubly-fed machines has been described. We propose in this paper new rotary equipment for power system operations. That is doubly-fed rotary frequency converter, which consists of 2 machines that are directly connected each other with shaft, and they are a set of doubly-fed machine and synchronous machine or a couple of doubly-fed machines. Analytical models were newly developed in order to analyze and understand the behavior of the proposed doubly-fedrotary frequency converter. Basic control scheme for the doubly-fed rotary frequency converters is proposed. Results of studies on dynamic characteristics of the control systems applied in the converters are shown. Moreover, merits and demerits were discussed in comparison with static DC converter with thyristor valves from the practical point of view.

Subspace signal-to-noise ratio maximization: the constrained stochastic matched filter (2006)

International audience
Filter‐less power allocation and regulation scheme with the prototypic implementation (2020)

Microgrids are often accomplished with power‐dense and energy‐dense hybrid storage systems for the assured improvement in the stability and the awake time. The conventional droop based steady‐state power bifurcation strategies for the energy‐dense storage elements can efficiently improve the awake time. However, the improvement in the stability and the robustness demands accurate transient demand allocation. The constant cut‐off frequency‐based physical power decomposition filter cannot ensure an accurate transient demand allocation, particularly, while the demand is fluctuating and uncertain. Therefore, the study proposes the concept of pseudo‐power decomposition filter. The concept of the pseudo‐decomposition filter has been executed for the microgrid through the novel selected power component droop. The real‐time performance of the proposed concept has been evaluated in the BTS‐7960 packaged‐Metal Oxide Semiconductor Field Effect Transistor (MOSFET) ‐based hardware platform, regularised through the ARM Cortex A‐72 based digital signal processor. In respect to the conventional linear droop, the improvement through the concept in the power decomposition and the allocation of transient demands is significant.
