SocioNet: A Social-Based Multimedia Access System for Unstructured P2P Networks (2009)

Increasingly, peer-to-peer (P2P) network users expect to be able to search objects by semantic attributes based on their preferences for multimedia content. Partial match search (i.e., search through the use of multimedia content semantic information) has become an essential service in P2P systems. In this paper, we propose SocioNet, a social-based overlay that clusters peers based on their preference relationships as a small-world network. In SocioNet, peers mimic how people form a social network and how they query, by preference, their friends or acquaintances. Hence, SocioNet benefits from two desirable features of a social network: interest-based clustering and small-world properties (i.e., high cluster coefficient among all peers yet short path lengths between any two peers). To realize an interest-based small-world SocioNet, we also investigate the following practical design issues: 1) similarity estimation: we define a quantifiable similarity measure that enables clustering of similar peers in SocioNet; 2) distributed small-world overlay adaptation: peers maintain a small-world overlay under network dynamics; and 3) query strategy under the small-world overlay: we analyze appropriate settings for the Time-to-Live (TTL) value, for TTL-limited flooding, that provides a satisfactory success ratio and avoids redundant message overhead. We use simulations and a real database called AudioScrobbler [CHECK END OF SENTENCE], which tracks users' listening habits, to evaluate the performance of SocioNet. The results show that SocioNet assists peers in locating content at peers with similar interests through short path lengths, and hence, achieves a higher success ratio (than nonsmall-world interest-based overlays and noninterest-based small-world overlays) while reducing message overhead significantly.
Optical sensory arrays for the detection of urinary bladder cancer‐related volatile organic compounds (2018)

Non-invasive detection of urinary bladder cancer remains a significant challenge. Urinary volatile organic compounds (VOCs) are a promising alternative to cell-based biomarkers. Herein, we demonstrate a novel diagnosis system based on an optic fluorescence sensor array for detecting urinary bladder cancer VOCs biomarkers. This study describes a fluorescence-based VOCs sensor array detecting system in detail. The choice of VOCs for the initial part was based on an extensive systematic search of the literature and then followed up using urinary samples from patients with urinary bladder transitional cell carcinoma. Canonical discriminant analysis and partial least squares discriminant analysis (PLS-DA) were employed and correctly detected 31/48 urinary bladder cancer VOC biomarkers and achieved an overall 77.75% sensitivity and 93.25% specificity by PLS-DA modelling. All five urine samples from bladder cancer patients, and five healthy controls were successfully identified with the same sensor arrays. Overall, the experiments in this study describe a real-time platform for non-invasive bladder cancer diagnosis using fluorescence-based gas-sensor arrays. Pure VOCs and urine samples from the patients proved such a system to be promising; however, further research is required using a larger population sample.
Facile approach to functionalizing polymers with specific chemical groups by an ozone treatment: Preparation of crosslinkable poly(vinylidene fluoride) possessing benzoxazine pendent groups (2007)

A facile method for modifying a polymer with specific chemical groups was conducted through the incorporation of hydroxylbenzene groups into an ozone-treated polymer. The hydroxylbenzene pendent groups on the functionalized polymer provided reactive sites for further chemical reaction and modification. A poly(vinylidene fluoride) possessing benzoxazine pendent groups (PVDF-Bz) was prepared to demonstrate this polymer modification. The performance of the polymer functionalization and chemical structure characterization were determined with Fourier transform infrared, 1H NMR, ultraviolet–visible spectroscopy, and elemental analysis. PVDF-Bz was a crosslinkable polymer, and the crosslinked poly(vinylidene fluoride) exhibited improved mechanical properties.

Investigation of post-transcriptional gene regulatory networks associated with autism spectrum disorders by microRNA expression profiling of lymphoblastoid cell lines (2010)

Findings from this study strongly suggest that dysregulation of miRNA expression contributes to the observed alterations in gene expression and, in turn, may lead to the pathophysiological conditions underlying autism.
Strategies for Targeting Lentiviral Vectors (2008)

Vectors derived from retroviruses such as lentiviruses and onco-retroviruses are probably among the most suitable tools to achieve a long-term gene transfer since they allow stable integration of a transgene and its propagation in daughter cells. Lentiviral vectors should be preferred gene delivery vehicles over vectors derived from onco-retroviruses (MLV) since in contrast to the latter they can transduce non-proliferating target cells. Moreover, lentiviral vectors that have the capacity to deliver transgenes into specific tissues are expected to be of great value for various gene transfer approaches in vivo. Here we provide an overview of innovative approaches to upgrade lentiviral vectors for tissue or cell targeting and which have potential for in vivo gene delivery. In this overview we distinguish between three types of lentiviral vector targeting strategies (Fig 1): 1) targeting of vectors at the level of vector-cell entry through lentiviral vector surface modifications; 2) targeting at the level of transgene transcription by insertion of tissue specific promoters into lentiviral vectors; 3) a novel microRNA technology that rather than targeting the ‘right’ cells will ‘detarget’ transgene expression from non-target cells while achieving high expression in the target-cell. It is clear that each strategy is of enormous value for several gene therapy approaches but combining these three layers of transgene expression control will offer tools to really overcome several drawbacks in the field such as side-effect of off-target expression, clearance of transgene modified cells by immune response to the transgene and lack of biosecurity and efficiency in in vivo approaches.

Transcranial Direct Current Stimulation Effects on Athletes’ Cognitive Performance: An Exploratory Proof of Concept Trial (2016)

Among the 2016 Olympic and Paralympic Games' unforgettable moments, one could not overlook performances by Phelps and Bolt, which challenge old premises about the maximum extension of individual supremacism in ultracompetitive modalities and the doping scandals. Different media channels resonated these two trends, with an unseen rise on discussions about traits and practices that may set ultrahigh performance athletes apart from the more ordinary ones. Yet, some key issues remain undebated. This paper aims to add to this debate, with a proof of concept trial, which investigates whether transcranial direct current stimulation (tDCS) may serve as an aid for professional athletes. Ten professional athletes of three different modalities (judo, <i>N</i> = 4 athletes, swimming, <i>N</i> = 3 athletes, and rhythmic gymnastics, <i>N</i> = 3 athletes) received anodal stimulation (2 mA) for 20 min on the left dorsolateral prefrontal cortex for ten consecutive weekdays. We observed a positive effect of tDCS in their cognitive performance, including a significant improvement in alternated, sustained, and divided attention and in memory scores. We also observed a decrease in Beck Depression Inventory scores (4.50 points) in this non-clinical population. These preliminary results suggest that tDCS sessions may translate into competitive advantages for professional athletes and recommend the deepening of the discussion on its ethical use in sports, which is ultimately tied to the wider debate around the risks and opportunities that neuromodulation brings to the table.
Regulation of gene expression by transcription factors Ets‐1 and Ets‐2 (1994)

The ETS family of transcription factors have a DNA-binding domain in common that binds a core GGA(A/T) DNA sequence. A large number of proteins have now been identified that contain an ETS DNA-binding domain (see review by Wasylyk et al., 1993). Ets-1 was first described as the cellular homolog of v-ets. which is translated as a 135-kDa gag-myb-ets fusion protein from the replication-deficient retrovirus E26 in chickens. Ets-2 was subsequently described as a closely related protein that contains the highly conserved ETS DNA-binding domain. This paper considers the manner by which the two closely related genes, Ets-1 and Ets-2, apparently play distinct roles in embryo development and in the immune system of adult mice. Although both Ets-1 and Ets-2 transform fibroblasts (Seth et al., 1989), the temporal and tissue-specific expression patterns suggest that these two proteins play distinct biological roles and consequently transactivate different downstream cellular target genes.
Development of a Process for Toughening Grain-Refined, High-Strength Steels (1997)

There is a gradually increasing awareness of the deleterious effects of grain-refining precipitates on the Charpy V-notch impact toughness of high-strength steels, and recognition of these effects resulted in the development of a general process that provides substantial improvements in the ductile fracture resistance of tempered mar-tensite. The results of this investigation indicate that the processing-induced refinement of grain-refining precipitates also provides significant improvements in the lower-shelf and transition toughness of 3310, 8219 and 4340 steels tempered at 180‡C and 4340 steel tempered at 593‡C. In contrast to the upper-shelf regime, where the application of the process produces a change in either the mode or character of unstable fracture at constant strength and austenite grain size, the refinement of grain-refining precipitates is associated with an increased amount of ductile fracture and an increased resistance to the initiation of unstable crack propagation at any given temperature in the lower-shelf regime.
Towards Automatic Spell Checking for Arabic (2003)

Arabic’s rich morphology (word construction) and complex orthography (writing system) present unique challenges for automatic spell checking. An Arabic checker attempts to find a dictionary word that might be the correct spelling of the misspelled or misrecognized word In this paper, we report our attempt in developing an Arabic spelling checker program for solving this problem. Our approach is heuristic and involves developing an Arabic morphological analyzer, techniques of spelling checking and spelling correction, and efficient methods of lexicon operations. The developed Arabic spell checker is able to recognize common spelling errors for standard Arabic and Egyptian dialects. 1.
The contrast sensitivity of human colour vision to red‐green and blue‐yellow chromatic gratings. (1985)

A method of producing red-green and blue-yellow sinusoidal chromatic gratings is used which permits the correction of all chromatic aberrations. A quantitative criterion is adopted to choose the intensity match of the two colours in the stimulus: this is the intensity ratio at which contrast sensitivity for the chromatic grating differs most from the contrast sensitivity for a monochromatic luminance grating. Results show that this intensity match varies with spatial frequency and does not necessarily correspond to a luminance match between the colours. Contrast sensitivities to the chromatic gratings at the criterion intensity match are measured as a function of spatial frequency, using field sizes ranging from 2 to 23 deg. Both blue-yellow and red-green contrast sensitivity functions have similar low-pass characteristics, with no low-frequency attenuation even at low frequencies below 0.1 cycles/deg. These functions indicate that the limiting acuities based on red-green and blue-yellow colour discriminations are similar at 11 or 12 cycles/deg. Comparisons between contrast sensitivity functions for the chromatic and monochromatic gratings are made at the same mean luminances. Results show that, at low spatial frequencies below 0.5 cycles/deg, contrast sensitivity is greater to the chromatic gratings, consisting of two monochromatic gratings added in antiphase, than to either monochromatic grating alone. Above 0.5 cycles/deg, contrast sensitivity is greater to monochromatic than to chromatic gratings.

Enhanced thrombin generation in children with sickle cell disease. (1994)

Recent studies suggest that increased activity of the coagulation system, measured with sensitive assays for activation markers, may be important in the pathogenesis of vascular occlusion in sickle cell disease (SCD). Since most of these studies were carried out in adult patients and SCD is an inherited disorder with severe morbidity even in childhood, we decided to determine the activity of the coagulation system in children with SCD. In a prospective study markers of thrombin generation as well as coagulation inhibitors were investigated in 16 homozygous SCD patients and 16 age-matched control children. Significantly increased plasma concentrations of the prothrombin fragment F1+2 and of thrombin-antithrombin III (TAT) complexes were found in SCD patients. The levels of protein C activity and total and free protein S were significantly reduced in SCD patients as compared with control values. Plasma AT III levels were not different in the two groups. We conclude that, in children with SCD, evidence of enhanced thrombin generation is present, which may in part be due to reduced levels of the inhibitors proteins C and S. The clinical relevance of this coagulation imbalance has to be demonstrated.
Soil Moisture Retrieval Using GNSS-R Techniques: Experimental Results Over a Bare Soil Field (2009)

This paper presents a new technique to retrieve soil moisture using global navigation satellite signals reflected over the soil surface using the measurement of the power fluctuations of the signal created by the interference between the direct GPS signal and the one reflected over the soil surface. As a function of the elevation angle, power fluctuations at vertical polarization pass through a notch, which is related to the soil moisture content, while horizontal polarization exhibits a very weak dependence. Experimental results of the measurements obtained over a bare soil field are presented and discussed.

Loss-aware Binarization of Deep Networks (2016)

Deep neural network models, though very powerful and highly successful, are computationally expensive in terms of space and time. Recently, there have been a number of attempts on binarizing the network weights and activations. This greatly reduces the network size, and replaces the underlying multiplications to additions or even XNOR bit operations. However, existing binarization schemes are based on simple matrix approximation and ignore the effect of binarization on the loss. In this paper, we propose a proximal Newton algorithm with diagonal Hessian approximation that directly minimizes the loss w.r.t. the binarized weights. The underlying proximal step has an efficient closed-form solution, and the second-order information can be efficiently obtained from the second moments already computed by the Adam optimizer. Experiments on both feedforward and recurrent networks show that the proposed loss-aware binarization algorithm outperforms existing binarization schemes, and is also more robust for wide and deep networks.
Scalable, Cluster-based Anti-replay Protection for Wireless Sensor Networks (2007)

Large-scale wireless sensor network (WSN) deployments show great promise for military, homeland security, and many other applications. This promise, however, is offset by important security concerns. The resource constraints that typify wireless sensor devices make traditional security solutions impractical. One threat to secure sensor networks is the replay attack, in which packets are captured and replayed into the network. This type of attack can be perpetrated to confuse observers or to mount a denial-of-service or denial-of-sleep attack. Traditional techniques for anti-replay protection are too resource intensive for large-scale WSN deployments. While techniques for reducing data transmission overhead of WSN-speciflc anti-replay mechanisms have been explored, the important problem of minimizing per-node reply table storage requirements has not been addressed. This paper introduces Clustered Anti-Replay Protection or CARP, which leverages sensor network clustering to place a limit on the amount of memory required to store anti-replay information. We show that clustering keeps the memory required for anti-replay tables manageable, reducing the size from 30% of a Mica2's memory to 4.4% for a 200-node network. While the advantages of this technique are clear, the difficulty lies in securely updating network-wide anti-replay tables when the network reclusters, an event that must happen routinely to distribute energy consumption across the nodes in the network. Our mechanism distributes necessary anti-replay information in a secure, low-overhead, and completely distributed manner. We further show the energy-consumption overhead of adding anti-replay counters to network traffic across several WSN medium access control (MAC) protocols and two representative WSN platforms. On the Mica2 platform, overheads range from a 0% to 1.32% decrease in network lifetime, depending on the MAC protocol. On the Tmote Sky, overheads range from 0% to 4.64%. Providing anti-replay support in a secure, scalable, and distributed way is necessary to the overall security of future WSN deployments if they are to meet current expectations.
Towards ad hoc mobile multi-display environments on commodity mobile devices (2017)

We present a demonstration of HeadPhones (Headtracking + smart-Phones), a novel approach for the spatial registration of multiple mobile devices into an ad hoc multi-display environment. We propose to employ the user's head as external reference frame for the registration of multiple mobile devices into a common coordinate system. Our approach allows for dynamic repositioning of devices during runtime without the need for external infrastructure such as separate cameras or fiducials. Specifically, our only requirements are local network connections and mobile devices with built-in front facing cameras. This way, HeadPhones enables spatially-aware multi-display applications in mobile contexts.
