A General Design Framework for MIMO Wireless Energy Transfer With Limited Feedback (2016)

The multi-antenna or multiple-input multiple-output (MIMO) technique can significantly improve the efficiency of radio frequency (RF) signal enabled wireless energy transfer (WET). To fully exploit the energy beamforming gain at the energy transmitter (ET), the knowledge of channel state information (CSI) is essential, which, however, is difficult to be obtained in practice due to the energy and hardware limitation of the energy receiver (ER). To overcome this difficulty, under a point-to-point MIMO WET setup, this paper proposes a general design framework for a new type of channel learning method based on the ER's energy measurement feedback. Specifically, the ER measures and encodes the harvested energy levels over different training intervals into bits and sends them to the ET via a feedback link of limited rate. Based on the energy-level feedback, the ET adjusts transmit beamforming in subsequent training intervals and obtains refined estimates of the MIMO channel by leveraging the technique of analytic center cutting plane method (ACCPM) in convex optimization. Under this general design framework, we further propose two specific feedback schemes based on energy quantization and energy comparison, where the feedback bits at each interval are generated at the ER by quantizing the measured energy level at the current interval and comparing it with those in previous intervals, respectively. Numerical results are provided to compare the performance of the two feedback schemes. It is shown that energy quantization performs better when the number of feedback bits per interval is large, while energy comparison is more effective vice versa.
The Tissue-Engineered Human Psoriatic Skin Substitute: A Valuable In Vitro Model to Identify Genes with Altered Expression in Lesional Psoriasis (2018)

Psoriasis is a chronic inflammatory skin disease for which no cure has emerged. Its complex etiology requires the development of an in vitro model representative of the pathology. In this study, we exploited gene profiling analyses on microarray in order to characterize and further optimize the production of a human psoriatic skin model representative of this in vivo skin disease. Various skin substitutes were produced by tissue-engineering using biopsies from normal, healthy donors, or from lesional or non-lesional skin samples from patients with psoriasis, and their gene expression profiles were examined by DNA microarray. We demonstrated that more than 3540 and 1088 genes (two-fold change) were deregulated between healthy/lesional and lesional/non-lesional psoriatic substitutes, respectively. Moreover, several genes related to lipid metabolism, such as <i>PLA2G4E</i> and <i>PLA2G4C</i>, were identified as repressed in the lesional substitutes. In conclusion, gene profiling analyses identified a list of deregulated candidate genes associated with various metabolic pathways that may contribute to the progression of psoriasis.
Targeted Deletion of the PRL Receptor: Effects on Islet Development, Insulin Production, and Glucose Tolerance (2002)

PRL and placental lactogen (PL) stimulate beta-cell proliferation and insulin gene transcription in isolated islets and rat insulinoma cells, but the roles of the lactogenic hormones in islet development and insulin production in vivo remain unclear. To clarify the roles of the lactogens in pancreatic development and function, we measured islet density (number of islets/cm(2)) and mean islet size, beta-cell mass, pancreatic insulin mRNA levels, islet insulin content, and the insulin secretory response to glucose in an experimental model of lactogen resistance: the PRL receptor (PRLR)-deficient mouse. We then measured plasma glucose concentrations after ip injections of glucose or insulin. Compared with wild-type littermates, PRLR-deficient mice had 26-42% reductions (P < 0.01) in islet density and beta-cell mass. The reductions in islet density and beta-cell mass were noted as early as 3 wk of age and persisted through 8 months of age and were observed in both male and female mice. Pancreatic islets of PRLR-deficient mice were smaller than those of wild-type mice at weaning but not in adulthood. Pancreatic insulin mRNA levels were 20-30% lower (P < 0.05) in adult PRLR-deficient mice than in wild-type mice, and the insulin content of isolated islets was reduced by 16-25%. The insulin secretory response to ip glucose was blunted in PRLR-deficient males in vivo (P < 0.05) and in isolated islets of PRLR-deficient females and males in vitro (P < 0.01). Fasting blood glucose concentrations in PRLR-deficient mice were normal, but glucose levels after an ip glucose load were 10-20% higher (P < 0.02) than those in wild-type mice. On the other hand, the glucose response to ip insulin was normal. Our observations establish a physiologic role for lactogens in islet development and function.
MDPC-McEliece: New McEliece Variants from Moderate Density Parity-Check Codes. (2012)

Abstract. Cryptography based on coding theory is believed to resist to quantum attacks (all cryptosystems based on factoring/discrete logarithm can be quantum attacked in polynomial time). The McEliece cryptosystem is the oldest code-based cryptosystem and its security relies on two problems: the indistinguishability of the code family and the hardness of decoding random linear codes. The former is usually the weakest one. The main drawback of this cryptosystem regards its huge public-keys. Recently, several attempts to reduce its key-size have been proposed. Almost all of them were successfully broken due to the additional algebraic structure used to reduce the keys. In this work, we propose McEliece variants from Moderate Density Parity-Check codes. These codes are LDPC codes of higher density than what is usually adopted for telecommunication solutions. We show that our proposal strongly strengthens the security against distinguishing attacks and also provides extremely compact-keys. Under a reasonable assumption, MDPC codes reduce the distinguishing problem to decoding a linear code and thus the security of our proposal relies only on a well studied coding-theory problem. Furthermore, using a quasi-cyclic structure, we provide the smallest public-keys for code-based cryptosystem. For 80-bits of security, the public-key has only 4800 bits. In summary, this represents the most competitive code-based cryptosystem ever proposed and is a strong alternative for traditional cryptography.

Root Canals of Buried Teeth: Radiographic Changes due to Crystal Growth (1997)

The radiographs of 43 skulls recovered from a 4000-year-old site in Central Thailand were examined for changes in the pulp chamber and root canals of teeth. Eleven specimens aged between 8 and 40 years featured marked root canal radiopacities not consistent with the appearance of dentine. Scanning electron microscopy and electron microprobe analysis revealed the presence of crystals of almost pure calcium. The crystals had developed post-mortem, with the likely source of the mineral being sea shells which were abundant at the place of burial. © 1997 by John Wiley & Sons, Ltd.
Authentication and Identification Methods Used in Keystroke Biometric Systems (2015)

Keystroke dynamics authentication is not as widely used compared to other biometric systems. In recent years, keystroke dynamic authentication systems have gained interest because of low cost and integration with existing security systems. Many different methods have been proposed for data collection, feature representation, classification, and performance evaluation. The work presents a detailed survey of the most recent research in keystroke dynamic authentication. Research is evaluated by the conditions under which data was collected, classification algorithms used, and system performance. This work also identifies some shortcomings of the current research issues that need to be addressed for keystroke dynamics to mature. Some recommendations for future research are made, with the goal of improving keystroke dynamics system performance and robustness.
Automatic discovery of query-class-dependent models for multimodal search (2005)

We develop a framework for the automatic discovery of query classes for query-class-dependent search models in multimodal retrieval. The framework automatically discovers useful query classes by clustering queries in a training set according to the performance of various unimodal search methods, yielding classes of queries which have similar fusion strategies for the combination of unimodal components for multimodal search. We further combine these performance features with the semantic features of the queries during clustering in order to make discovered classes meaningful. The inclusion of the semantic space also makes it possible to choose the correct class for new, unseen queries, which have unknown performance space features. We evaluate the system against the TRECVID 2004 automatic video search task and find that the automatically discovered query classes give an improvement of 18% in MAP over hand-defined query classes used in previous works. We also find that some hand-defined query classes, such as "Named Person" and "Sports" do, indeed, have similarities in search method performance and are useful for query-class-dependent multimodal search, while other hand-defined classes, such as "Named Object" and "General Object" do not have consistent search method performance and should be split apart or replaced with other classes. The proposed framework is general and can be applied to any new domain without expert domain knowledge.
The caries experience of 11 to 12 year-old children in Scotland and Wales and 12 year-olds in England in 2008-2009: reports of co-ordinated surveys using BASCD methodology. (2012)

Caries prevalence surveys of children aged 11-12 years have been conducted across Great Britain. Those carried out with positive consent appear to produce unbiased results, comparable with previous surveys. Health inequalities in this age group persist, as does the burden of disease for those with end-stage caries.

Design and fabrication of an optical pressure micro sensor for skin mechanics studies (2006)

The mechanics of skin is as central to touch as optics is to vision and acoustics is to hearing.With the advent of novel imaging technologies such as the Optical Coherence Tomography (OCT), we are now able to view structures within the skin to a resolution of a few microns in vivo and noninvasively.To fully understand the role of biomechanics of the skin in interpreting touch, we need to develop a quantitative understanding of how spatio temporal loads imposed on the surface of the skin are transmitted to mechanoreceptor locations within the skin.The following thesis presents a description of the design and fabrication of an Optical Pressure Sensor Device to be used in conjunction with an Optical Coherence Tomography Apparatus to quantify loads incident on the fingerpad surface.
Amplitude-phase coupling in a spin-torque nano-oscillator (2009)

The spin-torque nano-oscillator in the presence of thermal fluctuation is described by the normal form of the Hopf bifurcation with an additive white noise. By the application of the reduction method, the amplitude-phase coupling factor, which has a significant effect on the power spectrum of the spin-torque nano-oscillator, is calculated from the Landau–Lifshitz–Gilbert–Slonczewski equation with the nonlinear Gilbert damping. The amplitude-phase coupling factor exhibits a large variation depending on an in-plane anisotropy under the practical external fields.
Suppression of stimulated Brillouin scattering during transmission of high-power narrowband laser light in monomode fibre (1982)

Dairy streptococcal cell wall and exopolysaccharide genome diversity (2022)

The large-scale and high-intensity application of Streptococcus thermophilus species in milk fermentation processes is associated with a persistent threat of (bacterio)phage infection. Phage infection of starter cultures may cause inconsistent, slow or even failed fermentations with consequent diminished product quality and/or output. The phage life cycle commences with the recognition of, and binding to, a specific host-encoded and surface-exposed receptor, which in the case of S. thermophilus can be the rhamnose-glucose polysaccharide (RGP; specified by the rgp gene cluster) or exopolysaccharide (EPS; specified by the eps gene cluster). The genomic diversity of 23 S . thermophilus strains isolated from unpasteurized dairy products was evaluated, including a detailed analysis of the rgp and eps loci. In the present study, five novel eps genotypes were identified while variations of currently recognized rgp gene cluster types were also observed. Furthermore, the diversity of rgp genotypes amongst retrieved isolates positively correlated with phage diversity based on phageome analysis of eight representative dairy products. Our findings therefore substantially expand our knowledge on S. thermophilus’ strain and phage diversity in (artisanal) dairy products and highlight the merit of phageome analysis of artisanal and traditional fermented foods as a sensitive marker of dominant microbiota involved in the fermentation.
False Negative Response From Caloric Stimulation (1973)

Greisen (1972) has recently drawn attention to “pseudocaloric nystagmus”. The present authors disagree with his interpretation of the evidence he puts forward, but offer an alternative explanation of his evidence and a method for detecting the phenomenon when it occurs. Their arguments also indicate the undesirability of shortening the bithermal caloric test to one temperature only, and the advantages of doing the hot tests before the cold ones.
Biologically-Inspired Multifunctional Composite Panel with Integrated Thermal Control (2010)

Recently, there has been a surge in interest in biologically inspired or bio-mimetic structures where living organisms are used to provide guidance to improve overall performance of aerospace systems. In this study, an isogrid architecture for satellite electronics panels was investigated. Fluidic channels were incorporated into the structure, thus providing thermal management capability in addition to structural support. To provide the surface area for heat transfer, a thin face-sheet was mounted on the outside of the isogrid, also containing fluidic channels. The fluidic channels are analogous to a circulatory system in a biological organism. The primary supporting ribs act as arteries by providing the main flow supply and channels in the face-sheet act as capillaries by providing the area coverage for heat transfer. The challenge with this concept is the requirement for complex, leak-free internal geometries to transport fluid throughout the panel as needed to cool the components and still provide a high stiffness-to-weight as required for satellite structures. Using a novel fabrication approach, the channels can be integrated directly into an isogrid composite panel during build up. This approach also eliminates the traditional failure point of composite isogrid structures by forming the rib structure and face-sheet into a single, multi-directional laminate. As a result of the fabrication approach, the size of the primary arterial fluid channels must be carefully designed to balance heat transfer, pressure losses, and face-sheet deflection. This paper reviews the design and optimization of the channel as well as the overall thermal design of the panel.

Localization of Intramolecular Monosulfide Bridges in Lantibiotics Determined with Electron Capture Induced Dissociation (2003)

Electron capture induced dissociation (ECD) and collisionally activated dissociation (CAD) experiments were performed on four lanthionine bridge-containing antibiotics. ECD of lantibiotics produced mainly c and z* ions, as has been observed previously with other peptides, but more interestingly, the less common c* and z ions were observed in abundance in the ECD spectra. These fragments specifically resulted from the cleavage of both a backbone amine bond and the thioether bond in a lanthionine bridge. ECD seemed to induce mainly cleavages near the lanthionine bridges. This fragmentation pattern indicates that lanthionine bridges play a key role in the selectivity of the ECD process. A new mechanism is postulated describing the formation of c* and z ions. Comparative low-energy CAD did not show such specificity. Nondissociative ECD products were quite abundant, suggesting that relatively stable double and triple radicals can be formed in the ECD process. Our results suggest that ECD can be used as a tool to identify the C-terminal attachment site of lanthionine bridges in newly discovered lantibiotics.
