Information processing via physical soft body (2015)

Soft machines have recently gained prominence due to their inherent softness and the resulting safety and resilience in applications. However, these machines also have disadvantages, as they respond with complex body dynamics when stimulated. These dynamics exhibit a variety of properties, including nonlinearity, memory, and potentially infinitely many degrees of freedom, which are often difficult to control. Here, we demonstrate that these seemingly undesirable properties can in fact be assets that can be exploited for real-time computation. Using body dynamics generated from a soft silicone arm, we show that they can be employed to emulate desired nonlinear dynamical systems. First, by using benchmark tasks, we demonstrate that the nonlinearity and memory within the body dynamics can increase the computational performance. Second, we characterize our system's computational capability by comparing its task performance with a standard machine learning technique and identify its range of validity and limitation. Our results suggest that soft bodies are not only impressive in their deformability and flexibility but can also be potentially used as computational resources on top and for free.
Wave-Follower Field Measurements of the Wind-Input Spectral Function. Part I: Measurements and Calibrations (2005)

Abstract An experimental study of wind energy and momentum input into finite-depth wind waves was undertaken at Lake George, New South Wales, Australia. To measure microscale oscillations of induced pressure above surface waves, a high-precision wave-follower system was developed at the University of Miami, Florida. The principal sensing hardware included Elliott pressure probes, hot-film anemometers, and Pitot tubes. The wave-follower recordings were supplemented by a complete set of relevant measurements in the atmospheric boundary layer, on the surface, and in the water body. This paper is dedicated to technical aspects of the measurement procedure and data analysis. The precision of the feedback wave-following mechanism did not impose any restrictions on the measurement accuracy in the range of wave heights and frequencies relevant to the problem. Thorough calibrations of the pressure transducers and moving Elliott probes were conducted. It is shown that the response of the air column in the connecting tubes provides a frequency-dependent phase shift, which must be accounted for to recover the low-level induced pressure signal. In the finite-depth environment of Lake George, breaking waves play an important role in the momentum exchange between wind and waves, as will be shown in a subsequent paper.
Carfilzomib, lenalidomide and dexamethasone followed by a second ASCT is an effective strategy in first relapse multiple myeloma: a study on behalf of the Chronic malignancies working party of the EBMT (2023)

In the setting of a first relapse of multiple myeloma (MM), a second autologous stem cell transplant (ASCT) following carfilzomib-lenalidomide-dexamethasone (KRd) is an option, although there is scarce data concerning this approach. We performed a retrospective study involving 22 EBMT-affiliated centers. Eligible MM patients had received a second-line treatment with KRd induction followed by a second ASCT between 2016 and 2018. Primary objective was to estimate progression-free survival (PFS) and overall survival (OS). Secondary objectives were to assess the response rate and identify significant variables affecting PFS and OS. Fifty-one patients were identified, with a median age of 62 years. Median PFS after ASCT was 29.5 months while 24- and 36-months OS rates were 92.1% and 84.5%, respectively. Variables affecting PFS were an interval over four years between transplants and the achievement of a very good partial response (VGPR) or better before the relapse ASCT. Our study suggests that a relapse treatment with ASCT after KRd induction is an effective strategy for patients with a lenalidomide-sensitive first relapse. Patients with at least four years of remission after a frontline ASCT and who achieved at least a VGPR after KRd induction appear to benefit the most from this approach.
Using graphics processors for high performance IR query processing (2009)

Web search engines are facing formidable performance challenges due to data sizes and query loads. The major engines have to process tens of thousands of queries per second over tens of billions of documents. To deal with this heavy workload, such engines employ massively parallel systems consisting of thousands of machines. The significant cost of operating these systems has motivated a lot of recent research into more efficient query processing mechanisms. We investigate a new way to build such high performance IR systems using graphical processing units (GPUs). GPUs were originally designed to accelerate computer graphics applications through massive on-chip parallelism. Recently a number of researchers have studied how to use GPUs for other problem domains such as databases and scientific computing. Our contribution here is to design a basic system architecture for GPU-based high-performance IR, to develop suitable algorithms for subtasks such as inverted list compression, list intersection, and top-$k$ scoring, and to show how to achieve highly efficient query processing on GPU-based systems. Our experimental results for a prototype GPU-based system on $25.2$ million web pages indicate that significant gains in query processing performance can be obtained.
Immunochemical differences among Methanosarcina mazei S-6 morphologic forms (1992)

Methanosarcinae are the only archaeobacteria known to undergo major morphologic changes during growth involving unicellular and multicellular forms, and Methanosarcina mazei S-6 is the only strain for which three distinct forms, packets, single cells, and lamina, have so far been observed. It is reported that two pairs of these forms, either packets and single cells or single cells and lamina, grew and interconverted in medium with the same composition, Ca2+ and Mg2+ concentrations, and growth substrate, and that the two forms in each pair displayed distinctive differences revealed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting, the same growth medium-substrate notwithstanding.
The Role of Collagen Cross-Links in Biomechanical Behavior of Human Aortic Heart Valve Leaflets—Relevance for Tissue Engineering (2007)

A major challenge in tissue engineering of functional heart valves is to determine and mimic the dominant tissue structures that regulate heart valve function and in vivo survival. In native heart valves, the anisotropic matrix architecture assures sustained and adequate functioning under high-pressure conditions. Collagen, being the main load-bearing matrix component, contributes significantly to the biomechanical strength of the tissue. This study investigates the relationship between collagen content, collagen cross-links, and biomechanical behavior in human aortic heart valve leaflets and in tissue-engineered constructs. In the main loading direction (circumferential) of native valve leaflets, a significant positive linear correlation between modulus of elasticity and collagen cross-link concentration was found, whereas no correlation between modulus of elasticity and collagen content was found. Similar findings were observed in tissue-engineered constructs, where cross-link concentration was higher for dynamically strained constructs then for statically cultured controls. These findings suggest a dominant role for collagen cross-links over collagen content with respect to biomechanical tissue behavior in human heart valve leaflets. They further suggest that dynamic tissue straining in tissue engineering protocols can enhance cross-link concentration and biomechanical function.
Numerical and experimental study on aluminium pipe bending process (2011)

In this paper the analysis of cold working bending process of the aluminum pipe was presented based on both numerical simulations and experimental tests. The parameters such as wall thickness above and below bending axis were compared and discussed for both numerical simulations and experimental tests. The numerical simulations were performed in Abaqus 6.9/CAE computational environment on the basis of finite element method while the bending machine was designed and constructed for the purpose of tests. The usefulness of numerical simulations was also discussed.
Temperature Dependence of the Elastic Constants of the Alkali Halides. III. CsCl, CsBr, and CsI (1967)

The elastic constants of CsCl, CsBr, and CsI have been measured from room temperature to 450°C. Measurements on CsCl were made up to its transition temperature at 473°C but no anomalous variations were found which would differentiate its behavior from that of CsBr and CsI. The results of the measurements are shown to be in agreement with previous experimental work. It is found that the type of temperature variation exhibited by c44 in the CsCl-type lattice is very similar to that observed for ½(c11–c12) in the NaCl-type structure. From a consideration of the respective ionic arrangements, these elastic constants can be seen to describe shear mechanisms which could lead to instability with a static expansion of the lattice. From such a treatment, a possible mechanism is suggested to describe the CsCl-type to NaCl-type structure transition. This mechanism is shown to be compatible with the existing data.
Effect of Cultivar and Explants Type on Tissue Culture Regeneration of Three Nigerian Cultivars of Tomatoes (2013)

&lt;p&gt;In order to assess the suitable explant(s) for &lt;em&gt;in-vitro&lt;/em&gt; regeneration of three local cultivars of Nigerian tomatoes, Ibadan local (IbL), Ife and JM94/46, cotyledon, hypocotyls and radicle explants were cultured in shoot regeneration medium consisting of&lt;strong&gt; &lt;/strong&gt;MS containing 30 g L&lt;sup&gt;-1&lt;/sup&gt; sucrose and 8 g L&lt;sup&gt;-1 &lt;/sup&gt;agar with no exogenous plant growth hormones. Forty-five of each explant type was cultured on the medium in triplicate experiments and results showed varied percentage survival and shooting for the various explants. Hypocotyl explants had the highest percentage of shooting explants at 13.3% for IbL; 6.67% for Ife and 20% in JM94/46. IbL cotyledon explants had 4.44% of shooting explants with no shoots recorded in Ife and JM94/46 cotyledon explants. IbL radicle explants had 2.22% shooting explants and no shoots recorded in Ife and JM94/46. Student Neuman Keuls (SNK) statistical analysis of cultivar-media interaction showed there was no significant difference (P &amp;gt; 0.05) among the three cultivars in number of calli and shooting calli. There was however significant difference among the cultivars in the number of shoots recorded. SNK values for explants-media interaction showed that cotyledon and radicle explants were significantly different (P &amp;lt; 0.05) from hypocotyl explants in the number of shoots produced.&lt;/p&gt;

Performance Modulation of Reverse Conducting IGBT through Gate-Voltage Adjustment in Diode Conduction Mode (2019)

While driving an RC-IGBT in diode conduction mode, the applied gate-emitter voltage is directly influencing the electron-hole plasma in the device. Thus, diode ON-state losses as well as the reverse-recovery behavior - tail and peak current - can be easily manipulated in order to suit specific inverter applications.
Non-invasive blood glucose measurement by near infrared spectroscopy: Machine drift, time drift and physiological effect (2010)

The aim of this paper is to evaluate development of the non-invasive blood glucose measurement of near infrared (NIR) spectroscopy. The results showed that NIR spectroscopy might obtain glucose concentration of up to 200% difference under a same environmental condition with two months apart due to time and machine drifts. These effects can restrict the development of the non-invasive blood glucose measurement. Partial least square (PLS) regression was used, which showed advantage over using simple absorbance for glucose concentration. Non-invasive blood glucose measurement of health subjects (non-diabetics) was also investigated. The results showed that R correlation coefficient of prediction ( R p ) was 0.48 and root mean square of prediction (rmsep) was 1.34 mmol/l. The error was mainly due to the physiological effect of different subjects.
Differential Privacy Guarantees for Stochastic Gradient Langevin Dynamics (2022)

We analyse the privacy leakage of noisy stochastic gradient descent by modeling Rényi divergence dynamics with Langevin diffusions. Inspired by recent work on non-stochastic algorithms, we derive similar desirable properties in the stochastic setting. In particular, we prove that the privacy loss converges exponentially fast for smooth and strongly convex objectives under constant step size, which is a significant improvement over previous DP-SGD analyses. We also extend our analysis to arbitrary sequences of varying step sizes and derive new utility bounds. Last, we propose an implementation and our experiments show the practical utility of our approach compared to classical DP-SGD libraries.
Descriptive Epidemiology of Acetabular Dysplasia: The Academic Network of Conservational Hip Outcomes Research (ANCHOR) Periacetabular Osteotomy (2017)

Patients undergoing PAO for symptomatic dysplasia were predominantly young, female, and Caucasian with a normal BMI. Many patients had undergone prior hip surgery, and most had had symptoms for several years before treatment. Baseline patient-reported functional scores demonstrated marked functional limitations. Adjunctive procedures for intra-articular pathology, especially femoral osteochondroplasty and hip arthroscopy, are commonly performed at the time of PAO.
Using iDocument for Document Categorization in Nepomuk Social Semantic Desktop. (2009)

Abstract On the Semantic Desktop users maintain their model of the world in a formal personal information model ontology. Concepts from this ontology are used to annotate documents from desktop, allowing efficient navigation and browsing of these. However, the mental overhead required for correctly classifying new incoming document is substantial. We present the integration of the ontology-based informa-tion extraction system iDocument into the Nepomuk Semantic Desktop for classifying documents within the personal information model. A comparison is done between iDoc-ument and the original classification system Structure Recommender. It is based on real models and documents from five Nepomuk users. Results reveal evidences that iDocument’s categorization proposals are rated with higher recall and precision values and show that iDocument’s result ranking corresponds to user ratings. Key Words: semantic desktop, ontology-based information extraction, text classifi-cation, personal information model

The Microbiome of Endophytic, Wood Colonizing Bacteria from Pine Trees as Affected by Pine Wilt Disease (2017)

Pine wilt disease (PWD) is a devastating forest disease present worldwide. In this study we analyzed the effects of the invasion of the pinewood nematode Bursaphelenchus xylophilus, the major pathogen causing PWD, on the endophytic microbiome of adult P. pinaster trees. Wood samples from trees with different degrees of PWD disease were collected at two sites (A and M) in Portugal. Endophytic bacteria were characterized based on directly extracted DNA by fingerprinting and barcoding using the 16S rRNA gene as marker. Furthermore, cultivation-based approaches were used to obtain isolates of the major taxa to study their ecophysiology. The endophytic microbiome from P. pinaster trees differed significantly between the two sampling sites. Main bacterial OTUs belonged to the Proteobacteria (39% (site M) - 97% (site A)), and Firmicutes (0.70% (site A) - 44% (site M)). However, consequences of the invasion with the pathogen were comparable. Interestingly diversity of wood endophytic bacteria increased with the severity of the diseases, with highest diversity levels observed in in the most affected trees. Our results suggest that in the first stages of the disease, the defence mechanisms of plants are repressed by the pathogen, resulting in a colonization of the wood interior by soil microorganisms.
How Does the Addition of Gel at the Time of Vaccination Affect Overall Nursery Pig Performance? (2008)

Swine industry feed suppliers are continually striving to create techniques and tools to reduce the additive stressors imposed on the weanling piglet, to increase advantageous behaviors (feeding and drinking) and to reduce aggrieve interactions. In addition to social reorganization, pigs are often vaccinated during the nursery phase to reduce the impact of potentially harmful diseases. It has been noted by swine practitioners that at the time of vaccination many pigs lie down, rest more and reduce the amount of feed consumption over the vaccination period. One product on the market is a gel-based feed that is designed to ease the transition from a liquid diet (sow's milk) to dry ration. This gel-based feed contains high quality ingredients; it is highly palatable and provides the young pig with both a feed component and a water component thereby influencing feed consumption and intestinal health. The gel can be used in addition to a standard weaned pig solid ration. Although, often recommended to be used at the time of weaning, the possibilities of implementing the gel around the time of vaccination is a novel concept that might impact the individual pig’s overall performance. The objectives of this study were to determine if the addition of gel at the time of vaccination provided benefits to the nursery pigs’ performance.
Engagement Zone Defense of a Non-Maneuvering Evader (2021)

This paper considers a three agent scenario consisting of a pursuer, evader, and a defender. The pursuer’s objective is to capture the non-maneuvering evader in minimum time while a defender aims at maximize contact with the pursuer by keeping the pursuer inside his circular engagement zone for as long as possible; the pursuer is considered to be faster than both the evader and the defender. Using optimal control theory, the optimal control for the defender that maximizes contact with the pursuer is posed and solved. In the event that the evader is captured by the pursuer before the pursuer escapes the engagement zone of the defender, some suboptimal strategies of the defender provide equivalent contact time. A derivation of defender’s headings that maximize contact is presented along with examples that highlight the importance of the initial conditions of the engagement scenario.
Metallorganic Chemical Vapor Deposition of TaO[sub x]N[sub y] as a High-Dielectric-Constant Material for Next-Generation Devices (2002)

Tantalum oxynitride films were deposited by metallorganic chemical vapor deposition. Pentaethoxytantalum the most widely used source gas for depositing was used as the source gas and as the reaction gas. The activation energy of the surface reaction was estimated to be 1.1 eV for a single-source deposition deposition), and to decrease to ca. 0.37 eV with the addition of over 50 sccm Deposition rate at the surface-reaction-controlled regime increased to 2.6 nm/min with 100 sccm but decreased upon adding more than 100 sccm of The overall deposition rate of the surface-reaction-controlled regime was as predicted by the Langmuir-Hinshelwood model. With an increase in both deposition temperature and flow rate, the TaON phase predominated over The dielectric constants of the as-deposited and -annealed films were 51 and 146, respectively. It is believed that films are attractive high-dielectric-constant materials for the next generation of gigabit dynamic random access memory devices. However, films exhibit relatively high current leakage densities of to at 1.0 MV/cm. A porous film microstructure was observed by transmission electron microscopy, and this seemed to be responsible for these high leakage currents. Further systematic optimization of the deposition and annealing processes is needed to produce a dense microstructure with a low leakage current level. © 2002 The Electrochemical Society.

Low-Voltage Silicon Photonic MEMS Switch with Vertical Actuation (2021)

We present a vertically movable silicon photonic MEMS switch realized in IMEC's standard silicon photonics platform followed by a dedicated postprocessing for MEMS release. The device has six optical ports, which enable four switching configurations with a safe electrical isolation of the switch's actuator. A low actuation voltage of 3.75 V is required to efficiently switch the optical signal from the drop port to the through port of the device. The device exhibits port extinctions of 16 dB and 26 dB at its OFF and ON states, respectively. With an insertion loss of <; 2 dB and a broad 3 dB-bandwidth > 35 nm, this component paves the way for low-power scalable circuits in MEMS-enabled silicon photonics.
Constrictive Pericarditis Presenting as Pleural Effusion of Unknown Origin (1989)

Despite the known association of pleural effusion with constrictive pericarditis, the presentation of constrictive pericarditis as pleural effusion of unknown origin has, to our knowledge, never been described. After evaluating such a case, we retrospectively analyzed all cases of established constrictive pericarditis seen in this institution in the last six years. The clinical and laboratory features of this cohort of 30 patients are similar to those of other reported series. Pleural effusion was present in 18 (60%) of 30 cases. In six (12%) of the 18 cases, pleural effusion was a major component of the clinical presentation, and in three (10%) of these six cases, the persistence of pleural effusion of unknown origin was the indication for referral to this institution. Analysis of pleural fluid in four cases revealed three exudates and one transudate. We believe this is the first report of unexplained pleural effusion as the presenting manifestation of constrictive pericarditis, and this diagnosis should be added to the list of causes of unexplained pleural effusion.
