An Internet of Things Example: Classrooms Access Control over Near Field Communication (2014)

The Internet of Things is one of the ideas that has become increasingly relevant in recent years. It involves connecting things to the Internet in order to retrieve information from them at any time and from anywhere. In the Internet of Things, sensor networks that exchange information wirelessly via Wi-Fi, Bluetooth, Zigbee or RF are common. In this sense, our paper presents a way in which each classroom control is accessed through Near Field Communication (NFC) and the information is shared via radio frequency. These data are published on the Web and could easily be used for building applications from the data collected. As a result, our application collects information from the classroom to create a control classroom tool that displays access to and the status of all the classrooms graphically and also connects this data with social networks.
New poly(amide‐imide)s syntheses. VIII. Preparation and properties of poly (amide‐imide)s derived from 2,3‐bis(4‐aminophenoxy)naphthalene, trimellitic anhydride, and various aromatic diamines (1994)

Abstract The new polymer‐forming diimide‐diacid, 2,3‐bis(4‐trimellitimidophenoxy) naphthalene (I), was readily obtained by the condensation reaction of 2,3‐bis (4‐aminophenoxy) naphthalene with trimellitic anhydride. A series of novel aromatic poly (amide‐imide)s were prepared by the direct polycondensation of diimide‐diacid I with various aromatic diamines using triphenyl phosphite in N ‐methyl‐2‐pyrrolidone (NMP)/pyridine solution containing dissolved calcium chloride. The resultant polymers have inherent viscosities in the range of 0.65–1.02 dL/g at 30°C in N, N ‐dimethylacetamide. These polymers were readily soluble in various organic solvents and could be cast into transparent, tough, and flexible films. Their casting films showed tensile strength at break up to 86 MPa, elongation to break of 5–9%, and initial moduli up to 2.35 GPa. The wide‐angle X‐ray diffraction revealed that those polymers containing p ‐phenylene or p ‐oxyphenylene group are partially crystalline, and the other polymers are evidenced as amorphous patterns. These polymers show a glass transition in the range of 213–290°C in their differential scanning calorimetry (DSC) traces. The thermal stability of the polymers was evaluated by thermogravimetry analysis, which showed the 10% weight‐loss temperatures in the range of 508–565°C in nitrogen and 480–529°C in air atmosphere. © 1994 John Wiley &amp; Sons, Inc.
TRPV4 channels regulate tumor angiogenesis through the modulation of Rho‐dependent tumor endothelial cell mechanosensitivity (2012)

Tumor vessels are characterized by abnormal morphology and patterning that cause vascular hyperpermeability and inefficient delivery of anti‐cancer agents. We have previously shown that tumor vessel malformations may arise from aberrant Rho‐mediated mechanosensitivity of tumor‐derived capillary endothelial (CE) cells to mechanical cues, in particular blood flow‐induced cyclic strain. Here, we demonstrate that the expression and function of TRPV4, a mechanosenstive ion channel required for CE cell reorientation, is significantly lower in tumor CE cells compared to normal CE cells. Overexpression of TRPV4 increased GSK1016790A‐induced calcium influx in tumor CE cells and restored their shape sensitivity to substrate elasticity. Further, TRPV4 overexpression resulted in the suppression of the endogenously high Rho that, we previously showed, is implicated in aberrant mechanosensitivity of tumor CE cells. Importantly, overexpression of TRPV4 alone normalized the aberrant capillary formation and abnormal migration by tumor‐derived CE cells in vitro . Finally, tumor xenograft experiments revealed that, compared to tumors in wild type mice, those in TRPV4 KO mice exhibit a greater degree of vascular abnormality, as demonstrated by increased vessel diameter and reduced pericyte coverage, as well as enhanced growth. This work, therefore, demonstrates the critical role of TRPV4 channels in tumor endothelial cell mechanosensitivity and offers a novel therapeutic target for normalizing tumor vessel malformations and improving cancer drug delivery.
On computing the minimum distance for faster than Nyquist signaling (1990)

The degradation suffered when pulses satisfying the Nyquist criterion are used to transmit binary data at a rate faster than the Nyquist rate over the ideal band-limited (brick-wall) channel is studied. The minimum distance between received signals is used as a performance criterion. It is well-known that when Nyquist pulses (i.e. pulses satisfying the Nyquist criterion) are sent at the Nyquist rate, the minimum distance between signal points is the same as the pulse energy. The main result is to show that the minimum distance between received signals is the same as the pulse energy for rates of transmission about 25% beyond the Nyquist rate, which is the best possible result. In fact, one can even identify the precise error event and signaling rate that causes the minimum distance to be no longer equal to the pulse energy. The mathematical formulation of the problem is analyzed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Mechanical Properties and Microstructure of AZ31B Magnesium Alloy Processed by I-ECAP (2013)

Abstract Incremental equal channel angular pressing (I-ECAP) is a severe plastic deformation process used to refine grain size of metals, which allows processing very long billets. As described in the current article, an AZ31B magnesium alloy was processed for the first time by three different routes of I-ECAP, namely, A, B C , and C, at 523 K (250 °C). The structure of the material was homogenized and refined to ~5 microns of the average grain size, irrespective of the route used. Mechanical properties of the I-ECAPed samples in tension and compression were investigated. Strong influence of the processing route on yield and fracture behavior of the material was established. It was found that texture controls the mechanical properties of AZ31B magnesium alloy subjected to I-ECAP. SEM and OM techniques were used to obtain microstructural images of the I-ECAPed samples subjected to tension and compression. Increased ductility after I-ECAP was attributed to twinning suppression and facilitation of slip on basal plane. Shear bands were revealed in the samples processed by I-ECAP and subjected to tension. Tension–compression yield stress asymmetry in the samples tested along extrusion direction was suppressed in the material processed by routes B C and C. This effect was attributed to textural development and microstructural homogenization. Twinning activities in fine- and coarse-grained samples have also been studied.

Sensei &#x2014; a flexible testbed for heterogeneous wireless sensor networks (2009)

We present Sensei - a nomadic, relocatable, wireless sensor network (WSN) testbed with support for mobile nodes. The nomadism makes it possible to evaluate a WSN application in different environments ranging from lab environments to in- situ installations to prototype deployments. Other WSN testbeds are often static and can not be easily moved between sites. We also support reproducibility mobility in the testbed, using robots or humans as actuators with movement patterns defined in mobility scripts.

Levels of exhaled carbon monoxide in healthy active and passive smokers. (2015)

For non-smokers, the study identified a significant relationship between the level of exhaled CO and the participants' gender (p < 0.05), weight (p = 0.003), and height (p = 0.0005). For smokers, there is a relationship between the level of eCO and the daily cigarette consumption (p = 0.01), the type of cigarettes most frequently smoked (p < 0.05) and the favoured cigarette brand (p = 0.005).
Robust Video Watermarking Approach Based on Crowdsourcing and Hybrid Insertion (2017)

A novel robust video watermarking scheme is proposed in this paper, in which crowdsourcing technique is used to extract the most important regions from the original video. In fact, these regions are obtained by interacting with users and analyzing their behaviors while using an interactive interface where the summaries of the videos are given. The obtained regions are then detected in the mosaic frame of the video and merged with the region covered by all the moving objects in the mosaic. For the embedding step, a hybrid multi-signatures algorithm is proposed based on the two transforms DWT-SVD and the LSB method. Experimental results showed a high level of the visual quality of the watermarked videos thanks to the efficient choice of the embedded target, a good capacity, as well as a good robustness against the most important attacks like collusion and compression. In more, the comparative study carried out showed that the proposed algorithm exceeds the state of the art.
Algorithm for adjustment of DDR write interface timing (2008)

While the demand for memory capacity and performance continues to increase, current DDR-2 memory implementations start to encounter limitations. At high data rates of 533 MT/s and above, it becomes increasingly difficult to support greater than two DIMMs on a single DDR channel due to board routing and timing constraints. Supporting different combinations of DDR-2 raw card types on the same platform also complicates the timing and routing due to the possible variations in load. This paper outlines a method of achieving higher data rates of DDR-2 while supporting multiple DIMM configurations on a single platform by utilizing hardware circuitry in the memory controller in connection with software algorithms to adjust the DDR signal timing relationships based on the populated memory configuration. The algorithm also compensate for the effects of ageing over the lifetime of the part. The techniques used in this work are related to DDR-2 but could also be applicable to DDR-3 and future technologies.
Classification between non-multiple fallers and multiple fallers using a triaxial accelerometry-based system (2011)

Falls are a prominent problem facing older adults and a common cause of hospitalized injuries. Accurate falls-risk assessment and classification of falls-risk levels will provide useful information for the prevention of future falls. This study presents a triaxial accelerometer (TA) based two-class classifier, which discriminates between multiple fallers and non-multiple fallers, using a directed-routine (DR) movement test. One-hundred-and-twenty-six features were extracted from the accelerometry signals, recorded during the DR tests using a waist mounted TA, from 68 subjects. A linear multiple regression model was employed to map a subset of these features to an estimate of the number of previous falls experienced in the preceding twelve months. A simple threshold is applied to this estimated number of falls to create a basic linear discriminant classifier to separate multiple from non-multiple fallers. The system attained an accuracy of 71% in classifying the exact number of falls experienced in the last 12 months and 97% in identifying multiple fallers.
The spatio-temporal strain distribution in inhomogeneous poroelastic phantoms (2009)

The presence of a mobile fluid in a porous tissue modifies aspects of the tissue's mechanical behaviour such as the time variation of strain induced by a sustained compression. Elastography can be used to follow such responses and to estimate poroelastic parameters. This preliminary study examined axial strain variation in a poroelastic cylinder embedded in a quasi-elastic (or weakly permeable) background. Finite element analysis and experiment were compared. Unlike the case of purely elastic materials a region with high strain decaying with time was observed at the interface between the cylinder and the background. The time variation of strain in different regions of the phantom showed known poroelastic behaviour in that, as fluid was expelled, some regions contracted axially while others expanded axially. The strain relaxation time varied in a systematic manner in the different materials.
Breast Cancer: Insights into Risk Factors, Pathogenesis, Diagnosis and Management (2015)

Breast cancer is the most common invasive cancer in females worldwide. It usually presents with a lump in the breast with or without other manifestations. Diagnosis of breast cancer depends on physical examination, mammographic findings and biopsy results. Treatment of breast cancer depends on the stage of the disease. Lines of treatment include mainly surgical removal of the tumor followed by radiotherapy or chemotherapy. Other lines including immunotherapy, thermochemotherapy and alternative medicine may represent a hope for breast cancer patients.

A lead-on-sapphire superconducting cavity of superior quality (1986)

A cavity consisting of a superconducting lead film on a sapphire substrate has been fabricated to obtain the enhanced frequency stability possible with this configuration. The cavity exhibits a quality value Q exceeding 2×109 in its TE011 mode with a resonant frequency of 2.689 GHz. Methods of fabrication and testing of the cavity are presented in this article. Since the interface between the film and substrate is exposed to the full value of the resonant magnetic field, our experiment is the most sensitive test to date for enhanced losses at the interface itself. We find no evidence of such losses. In fact, the measured values of the surface resistance match very well predictions for rf losses based on the BCS theory.
Noise2Void - Learning Denoising From Single Noisy Images (2019)

The field of image denoising is currently dominated by discriminative deep learning methods that are trained on pairs of noisy input and clean target images. Recently it has been shown that such methods can also be trained without clean targets. Instead, independent pairs of noisy images can be used, in an approach known as Noise2Noise (N2N). Here, we introduce Noise2Void (N2V), a training scheme that takes this idea one step further. It does not require noisy image pairs, nor clean target images. Consequently, N2V allows us to train directly on the body of data to be denoised and can therefore be applied when other methods cannot. Especially interesting is the application to biomedical image data, where the acquisition of training targets, clean or noisy, is frequently not possible. We compare the performance of N2V to approaches that have either clean target images and/or noisy image pairs available. Intuitively, N2V cannot be expected to outperform methods that have more information available during training. Still, we observe that the denoising performance of Noise2Void drops in moderation and compares favorably to training-free denoising methods.
Weld Formation in Microgravity. (1998)

In order to investigate the effect of gravity on the formation of a weld, gas tungsten arc (GTA) welding was performed both in a microgravity environment and in a terrestrial environment. The microgravity environment was produced for 10 sec with less than 10-5 G by a drop-shaft type microgravity system at Japan Microgravity Center (JAMIC). The material used was an aluminum alloy. It has become clear that in the microgravity environment, the weld bead is formed flatly and a large amount of metal can be welded at once and in any welding position though the weld shape is significantly affected by gravity in the terrestrial environment. When helium rather than argon is used as a shielding gas, the butt weld is formed more flatly because the arc pressure is reduced. Judging from the distribution of the grain structures in the weld, in the microgravity environment, the temperature gradient is smaller than that in the terrestrial environment, and the degree of the constitutional supercooling is higher due to the absence of the heat transfer by gravity.

Development of High Strength Cold-rolled-phosphorus Steel Produced by Continuous Annealing (1982)

A high strength cold-rolled phosphorus-containing steel has been developed by continuous annealing process. The study is focussed on the improvement of Lankford value and aging characteristics of phosphorus-containing steel.The effects of coiling temperature after hot rolling and cold reduction on Lankford value have been investigated for a low C-low Mn-B-P steel. Investigations have also made clear the effects of cooling rate after continuous annealing on the precipitation rate and the size of precipitates of carbides. Experimental results show that (1) the combination of proper coiling temperature and large cold reduction results in high Lankford value over 1.5 and (2) the combination of high paint baking hardenability over 40 MPa with retarded aging property at room temperature can be obtained in the range of cooling rate from 10 to 100 deg C/s. The factors affecting such results are also discussed.

Comprehensive, Multidisciplinary Deep Brain Stimulation Screening for Parkinson Patients: No Room for “Short Cuts” (2014)

Careful, often cumbersome, screening is a fundamental part of DBS evaluation in Parkinson's disease (PD). It often involves a brain MRI, neuropsychological testing, neurological, surgical, and psychiatric evaluation, and "ON/OFF" motor testing. Given that DBS has now been a standard treatment for advanced PD, with clinicians' improved comfort and confidence in screening and referring patients for DBS, we wondered whether we can now streamline our lengthy evaluation process. We reviewed all PD patients evaluated for DBS at our center between 2006 and 2011 and analyzed the reasons for exclusion and for dropping out despite passing the screening process. A total of 223 PD patients who underwent DBS evaluation had complete charting. Only 131 (58.7%) patients were successfully implanted. Sixty-one (27.3%) patients were excluded after screening because of significant cognitive decline (32.7%), early disease with room for medication adjustment (29.5%), behavioral dysfunction (21.3%), suspected secondary parkinsonism or atypical parkinsonism syndrome (13.1%), PD, but with poor levodopa response (11.4%), unrealistic goals (9.8%), PD with predominant axial symptoms (6.5%), significant comorbidities (6.5%), or abnormal brain imaging (3.2%). In addition, 31 (13.9%) patients were cleared for surgery, but either chose not have it (18 patients), were lost to follow-up (12 patients), or were denied by medical insurance (1 patient). Through careful screening, a significant percentage of surgical candidates continue to be identified as less suitable because of a variety of reasons. This underscores the continued need for a comprehensive, multidisciplinary screening process.
