CAN MIGRATION OF THE PRESS-FIT REVISION FEMORAL STRAIGHT STEM (PFM-R) BE AVOIDED? SEARCH FOR PREDICTIVE FACTORS IN A RETROSPECTIVE SERIES OF 53 CASES (2008)

Purpose of the study: The revision modular femoral prosthesis (PFM-R) (Centerpulse) uses a cone-shaped straight femoral stem with winglets for press-fit revision fixation in the femoral shaft. The risk of secondary migration further into the shaft is well known. The purpose of this paper was to assess the degree of PFM-R stem migration and to search for predictive factors in order to better ascertain the limits of this type of revision anchorage in the femoral shaft. Material and methods: Fifty-three files (48 patients) were reviewed retrospectively at minimum none months follow-up. Mean patient age was 56.6 years. Revision was required for loosening (SOFCOT classification): grade 1 (n=5), grade 2 (n=8), grade 3 (n=17), grade 4 (n=10). For 13 hips, the implant to be replaced was not cemented (monobloc stem, infection), or a first-intention PFM-R. Results: Mean migration was 4.1 mm (0–17 mm), less than 5 mm in 73.5% of cases. There was no correlation between migration and SOFCOT grade. Conversely, there was a significant difference in migration between the grade 1 and grade 3B and between Paprosky grade 1 and 4 (p=0.05). The degree of migration was correlated with the length of the persistent isthma (p Discussion and conclusion: Use of a straight stem for anchorage in the femur is associated with secondary migration which depends on the quality of the bone in the anchorage zone and the extent of the press-fit. The persistence of a cone-shaped or cylindrical isthma measuring greater than 4 cm associated with a cortical index greater than 45% and a long wing anchorage can provide excellent primary stability. It would be useless to use long stems since they do not increase the quality of anchorage. The absence of an isthma and the presence of osteoporosis are limitations for this concept.

Why it is difficult to treat and prevent drug-resistant hypertension and elevated pulse pressure: the unrecognized roles of ionized hypomagnesemia, nitric oxide, ceramides, platelet-activating factor and epigenesis (2020)

Approximately 60 years ago, two of us, using diverse mammalian isolated arterial blood vessels, found that lowering the magnesium ion (Mg 2+ ) concentration in oxygenated Krebs-Ringer bicarbonate solution, surprisingly, would cause contraction; the lower the Mg 2+ , the greater the development of contractile force and vasoconstriction. 3- 17 After several of our findings were published, numerous other laboratories corroborated our reports. Approximately 35 years ago, our laboratories, using rats subjected to dietary deficiency of Mg, observed a progressive elevation in ABP with a progressive widening of PP.
Folding stability of the kinetoplastid membrane protein‐11 (KMP‐11) from Leishmania infantum (1999)

Kinetoplastid membrane protein-11 (KMP-11) is a major component of the cell surface of kinetoplastids, and acts as a potent B- and T-cell immunogen during Leishmania infection. Here we report that the Leishmania infantum KMP-11 secondary structure adopts mainly an alpha-helical conformation at pH 7.5 and that its urea- and thermally-induced unfolding constitute a fully reversible two-step process. This allows estimation of a half-denaturation temperature of approximately 65 degrees C, a delta GDH2O at 20 degrees C of approximately 14.63 kJ.mol-1, and an increment of the reaction heat of approximately 183.92 kJ.mol-1 and an entropy of approximately 543.4 J.mol-1.deg-1, respectively, for the native-denatured equilibrium of the KMP-11 in solution. We also report that the KPM-11 protein is induced to adopt a molten globule state at a pH range between pH 4 and pH 6. As a whole, the stability and the specific features of the denaturing effect induced by changes in pH are similar in KMP-11 to various other lipoproteins.
Chemisorption Properties and Structural Evolution of Pt−Si Intermetallic Thin Films Prepared by the Activated Adsorption of SiH4 on Pt(111) (1998)

The reaction of a silicon adlayer deposited on Pt(111) by chemical vapor deposition (CVD) using silane (SiH4) is described. Data from Auger electron spectroscopy (AES) reveal that Si readily diffuses into the Pt substrate and sequentially forms at least two unique intermetallic Pt−Si surface structural phases with (√7 × √7)R19.1° and (√19 × √19)R23.4° real space unit cells as characterized by low-energy electron diffraction (LEED). The chemisorption properties of each of the ordered overlayers were studied using CO as a molecular probe. Reflection−absorption infrared spectroscopy (RAIRS) and temperature-programmed desorption (TPD) studies indicated that CO was mostly limited to chemisorption at “atop” Pt sites in the √7 phase with a significant reduction of the heat of adsorption with respect to the Pt(111) surface. The √19 phase also showed a significant modification of the chemisorption properties although it is not as pronounced as that seen for the √7 structure. The relevance of these studies to intermetallic thin film growth is discussed.
Integral Invariants and Shape Matching (2006)

For shapes represented as closed planar contours, we introduce a class of functionals which are invariant with respect to the Euclidean group, and which are obtained by performing integral operations. While such integral invariants enjoy some of the desirable properties of their differential cousins, such as locality of computation (which allows matching under occlusions) and uniqueness of representation (asymptotically), they do not exhibit the noise sensitivity associated with differential quantities and therefore do not require pre-smoothing of the input shape. Our formulation allows the analysis of shapes at multiple scales. Based on integral invariants, we define a notion of distance between shapes. The proposed distance measure can be computed efficiently, it allows for shrinking and stretching of the boundary, and computes optimal correspondence. Numerical results on shape matching demonstrate that this framework can match shapes despite the deformation of subparts, missing parts, and noise. As a quantitative analysis, we report matching scores for shape retrieval from a database.
Trustworthy Data Collection From Implantable Medical Devices Via High-Speed Security Implementation Based on IEEE 1363 (2010)

Implantable medical devices (IMDs) have played an important role in many medical fields. Any failure in IMDs operations could cause serious consequences and it is important to protect the IMDs access from unauthenticated access. This study investigates secure IMD data collection within a telehealthcare [mobile health (m-health)] network. We use medical sensors carried by patients to securely access IMD data and perform secure sensor-to-sensor communications between patients to relay the IMD data to a remote doctor's server. To meet the requirements on low computational complexity, we choose N-th degree truncated polynomial ring (NTRU)-based encryption/decryption to secure IMD-sensor and sensor-sensor communications. An extended matryoshkas model is developed to estimate direct/indirect trust relationship among sensors. An NTRU hardware implementation in very large integrated circuit hardware description language is studied based on industry Standard IEEE 1363 to increase the speed of key generation. The performance analysis results demonstrate the security robustness of the proposed IMD data access trust model.
Development of General-Purpose Processing Element and Network-Based Dataflow Processing System: Part One (2009)

This research concerns a system, which is called Ubiquitous Multi-Processor (UMP) system, which constructs dataflow network dynamically by connecting function-specific execution modules. The software model of the system was developed consisting only of application-specific execution modules (SS-PE) providing fixed functions. We developed a general-purpose execution module (GP-PE) which performs equivalent function to SS-PE by downloading the software library to improve the efficiency of development and reconfigure the function dynamically. The GP-PE was evaluated on the loading time of the library, the processing time of a color space conversion application, and the configuration time of processing on a network. The results of evaluation show that the GP-PE achieves equivalent performance to the SS-PE. Furthermore, the GP-PE does not degrade the system performance regarding dynamic system configuration if the library becomes hundreds of megabytes. This result shows that the GP-PE is suitable for the UMP system in general use.
Hierarchical Porosity in Silica Thin Films by a One-Step Templating Strategy Using a Stimuli-Responsive Bioderived Glycolipid (2013)

Hierarchical porosity in thin films obtained with the evaporation induced self-assembly method is a major challenge that is generally accomplished by combining different templating compounds or strategies, each one typical for a given size range. For instance, for small–medium-sized pores (below 20 nm) a library of surfactants exists, while colloids and polymers, as well as phase separation and water condensation strategies, are used for large mesopores to macropores (up to several micrometers). Here, we report the pH-dependent templating effect using a class of entirely bioderived, functional glycolipids obtained from the culture broth of the yeast Starmerella bombicola. We show that these compounds can be used to achieve a micro-to-macro hierarchical porosity in a one-step process by simply tuning the solution pH and without using any additional cosurfactant, cosolvent, or pore-swelling agent. Small-angle X-ray scattering, transmission electron microscopy, scanning electron microscopy, and ellipsoporosimetry data show the multiscale porous texture of silica thin films.
Interference Coordination: Random Clustering and Adaptive Limited Feedback (2013)

Interference coordination improves data rates and reduces outages in cellular networks. Accurately evaluating the gains of coordination, however, is contingent upon using a network topology that models realistic cellular deployments. In this paper, we model the base stations locations as a Poisson point process to provide a better analytical assessment of the performance of coordination. Since interference coordination is only feasible within clusters of limited size, we consider a random clustering process where cluster stations are located according to a random point process and groups of base stations associated with the same cluster coordinate. We assume channel knowledge is exchanged among coordinating base stations, and we analyze the performance of interference coordination when channel knowledge at the transmitters is either perfect or acquired through limited feedback. We apply intercell interference nulling (ICIN) to coordinate interference inside the clusters. The feasibility of ICIN depends on the number of antennas at the base stations. Using tools from stochastic geometry, we derive the probability of coverage and the average rate for a typical mobile user. We show that the average cluster size can be optimized as a function of the number of antennas to maximize the gains of ICIN. To minimize the mean loss in rate due to limited feedback, we propose an adaptive feedback allocation strategy at the mobile users. We show that adapting the bit allocation as a function of the signals' strength increases the achievable rate with limited feedback, compared to equal bit partitioning. Finally, we illustrate how this analysis can help solve network design problems such as identifying regions where coordination provides gains based on average cluster size, number of antennas, and number of feedback bits.
From seduction to fulfillment (2003)

In this paper, we discuss the use of anthropomorphic form in the design of products. We assert that anthropomorphic form is not merely an embellishment but that it can be used as a means of solving design problems. Through a series of examples we illustrate the various uses of anthropomorphic form in the design of products. Our distinctions provide designers and researchers a way to classify and understand the use of anthropomorphic form in design and in doing so, increase the potential that anthropomorphic form be used in an appropriate and compelling manner.
Frequency-resolved measurements of the diffusion constant for ultrasonic waves in resonant multiple scattering media (2013)

Experimental measurements of the diffusion constant for ultrasonic waves (around 3 MHz) propagating in water through a random set of scatterers (parallel metallic rods arranged as a slab) are presented. The slab thickness is around ten times the transport mean free path. Transmitted waves are recorded over hundreds of emitting/receiving positions in order to estimate the ensemble-averaged transmitted intensity 〈I(x,t)〉. Focused beamforming is performed on both faces of the sample in order to mimic a set of point-like sources and receivers. In theory, under the diffusion approximation, the ratio of the off-axis intensity 〈I(x,t)〉 to the on-axis intensity 〈I(0,t)〉 shows a simple gaussian dependence on the lateral dimension x, independently from absorption or boundary conditions. This yields a simple way to estimate the diffusion constant D and therefore characterize the scattering medium. Based on that method, broadband as well as frequency-resolved measurements of the diffusion constant are presented in controllable model media, such as these forests of steel rods. Experimental results and difficulties for measuring a reliable value for D on a real sample are discussed.
AutoDMP (2023)

Macro placement is a critical very large-scale integration (VLSI) physical design problem that significantly impacts the design power-performance-area (PPA) metrics. This paper proposes AutoDMP, a methodology that leverages DREAMPlace, a GPU-accelerated placer, to place macros and standard cells concurrently in conjunction with automated parameter tuning using a multi-objective hyperparameter optimization technique. As a result, we can generate high-quality predictable solutions, improving the macro placement quality of academic benchmarks compared to baseline results generated from academic and commercial tools. AutoDMP is also computationally efficient, optimizing a design with 2.7 million cells and 320 macros in 3 hours on a single NVIDIA DGX Station A100. This work demonstrates the promise and potential of combining GPU-accelerated algorithms and ML techniques for VLSI design automation.
QUANTUM COMPUTATION WITH BALLISTIC ELECTRONS (2001)

We describe a solid state implementation of a quantum computer using ballistic single electrons as flying qubits in 1D nanowires. We show how to implement all the steps required for universal quantum computation: preparation of the initial state, measurement of the final state and a universal set of quantum gates. An important advantage of this model is the fact that we do not need ultrafast optoelectronics for gate operations. We use cold programming (or pre-programming), i.e. the gates are set before launching the electrons; all programming can be done using static electric fields only.
칩내장형 PCB 공정을 위한 칩 표면처리 공정에 관한 연구 (2012)

본 연구에서는 칩을 기판에 내장하기 위해 상용화된 CSR사의 bluetooth chip을 이용하여 표면의 솔더볼을 제거하고 PCB소재와 공정을 이용하는 embedded active PCB 공정에 관한 연구를 하였다. 솔더볼이 제거된 칩과 PCB는 구리 도금 공정으로 연결되었으나 열 충격시 표면처리를 하지 않았을 시 칩의 표면과 ABF 간의 de-lamination 현상이 발견되었고, 이를 해결하기 위해 칩의 polyimide passivation layer에 디스미어와 플라즈마 공정을 이용하여 조도 형성을 하는 연구를 진행하였다. SEM(Scanning Electron Microscope) 과 AFM(Atomic Force Micrometer)을 통하여 표면을 관찰하였고, XPS(X-ray Photoelectron Spectroscopy)를 이용하여 표면의 화학적 구조의 변화를 관찰하였다. 실험결과 플라즈마 처리 시 표면 조도형성이 되었으나 그 밀도가 조밀하지 못하였지만 디스미어 공정과 함께 처리하였을 시 조도의 조밀도가 높아 열 충격을 가하였을 시에도 칩의 polyimide layer와 ABF간의 de-lamination 현상이 발견되지 않았다. 【In this paper, the research of IC embedded PCB process is carried out. For embedding chips into PCB, solder-balls on chips were etched out and ABF(Ajinomoto Build-ip Film), prepreg and Cu foil was laminated on that to fabricate 6 layer build-up board. The chip of which solder ball was removed was successfully interconnected with PCB by laser drilling and Cu plating. However, de-lamination phenomenon occurred between chip surface and ABF during reflow and thermal shock. To solve this problem, de-smear and plasma treatment was applied to PI(polyimide) passivation layer on chip surface to improve the surface roughness. The properties of chip surface(PI) was investigated in terms of AFM(Atomic Force Micrometer), SEM and XPS (X-ray Photoelectron Spectroscopy). As results, nano-size anchor was evenly formed on PI surface when plasma treatment was combined with de-smear(NaOH+KMnO4) process and it improved thermal shock reliability ( $260^{\circ}C$ -10sec solder floating).】
Target recognition: fusing long-wave infrared and electro-optical imagery for detection of humans in a scene (2009)

We aim to identify humans in multimodal imagery by predicting the human long-wave infrared (LWIR) signature in a variety of scenarios. By adapting Tanabe's thermocomfort model, we simulate human body heat flow both between tissue layers (core, muscle, fat and skin) and between body segments (head, chest, upper arm, etc.). To assess the validity of our implementation, we simulated the conditions described in actual human subject studies, and compared our results to values reported in the literature. Inputs to the model include age, height, weight, clothing, physical activity and ambient conditions, including temperature, humidity and wind velocity. Iteration of heat transport equations and a thermoregulatory component yields temporal data of segment surface temperature. Our model was found to be in close agreement with experimentally collected data, with a maximum deviation from literature values of approximately 0.80%. By comparing the predicted human thermal signature to deblurred LWIR images and then fusing this information at the feature level with high-resolution electro-optical image data, we can facilitate identity detection of objects in a scene acquired under different conditions. Ultimately, our goal is to differentiate humans from their surroundings and label non-human objects as thermal clutter.
Review of Patents for Microneedle Application Devices Allowing Fluid Injections Through the Skin (2015)

Microneedles have been developed in the past few years as a new means of transdermal drug delivery. They indeed present many advantages compared to injections using hypodermic needles (reduced risk of contamination and epidermic reactions), but mostly bring comfort and compliance to patients. Microneedles may be plain, opening pathways for medications to dissolve into the skin, or hollow, allowing fluid to actually enter the dermis or the hypodermis. This review focuses on the latter type of microneedles and two issues with their application: first, ensuring correct insertion into the skin (controlled and repeatable insertion depth, mainly); and second, ensuring correct fluid delivery to the dermis (controlled infusion rate). This paper thus focuses on recently published patents for hollow microneedle applicators-i.e., microneedles applicators that allow fluid delivery to the skin. Descriptions are given of several of the most relevant patents concerning this. The benefits and drawbacks of the different solutions are also described.
Periodic Array of Polyelectrolyte-Gated Organic Transistors from Electrospun Poly(3-hexylthiophene) Nanofibers (2009)

High-performance organic field-effect transistors (OFETs) based on polyelectrolyte gate dielectric and electrospun poly(3-hexylthiophene) (P3HT) nanofibers were fabricated on a flexible polymer substrate. The use of UV-crosslinked hydrogel including ionic liquids for the insulating layer enabled fast and large-area fabrication of transistor arrays. The P3HT nanofibers were directly deposited on the methacrylated polymer substrate. During UV irradiation through a patterned mask, the methacrylate groups formed covalent bonds with the patterned polyelectrolyte dielectric layer, which provides mechanical stability to the devices. The OFETs operate at voltages of less than 2 V. The average field-effect mobility and on/off ratio were approximately 2 cm(2)/(Vs) and 10(5), respectively.
A new generation of ultra-dense optical I/O for silicon photonics (2014)

In response to the optical packaging needs of a rapidly growing silicon photonics market, Chiral Photonics, Inc. (CPI) has developed a new generation of ultra-dense-channel, bi-directional, all-optical, input/output (I/O) couplers that bridge the data transport gap between standard optical fibers and photonic integrated circuits. These couplers, called Pitch Reducing Optical Fiber Arrays (PROFAs), provide a means to simultaneously match both the mode field and channel spacing (i.e. pitch) between an optical fiber array and a photonic integrated circuit (PIC). Both primary methods for optically interfacing with PICs, via vertical grating couplers (VGCs) and edge couplers, can be addressed with PROFAs. PROFAs bring the signal-carrying cores, either multimode or singlemode, of many optical fibers into close proximity within an all-glass device that can provide low loss coupling to on-chip components, including waveguides, gratings, detectors and emitters. Two-dimensional (2D) PROFAs offer more than an order of magnitude enhancement in channel density compared to conventional one-dimensional (1D) fiber arrays. PROFAs can also be used with low vertical profile solutions that simplify optoelectronic packaging while reducing PIC I/O real estate usage requirements. PROFA technology is based on a scalable production process for microforming glass preform assemblies as they are pulled through a small oven. An innovative fiber design, called the “vanishing core,” enables tailoring the mode field along the length of the PROFA to meet the coupling needs of disparate waveguide technologies, such as fiber and onchip. Examples of single- and multi-channel couplers fabricated using this technology will be presented.
