Robust, Anonymous RFID Authentication with Constant Key-Lookup. (2007)

A considerable number of anonymous RFID authentication schemes have been proposed. However, current proposals either do not provide robust security guarantees, or suffer from scalability issues when the number of tags issued by the system is very large. In this paper, we focus on approaches that reconcile these important requirements. In particular, we seek to reduce the complexity of identifying tags by the back-end server in anonymous RFID authentication protocols—what we term the key-lookup problem. We propose a compiler that transforms a generic RFID authentication protocol (supporting anonymity) into one that achieves the same guarantees with constant key-lookup cost even when the number of tags is very large (billions of tags and beyond). This approach uses a lightweight one-way trapdoor function and produces protocols that are suitable for deployment into current tag architectures. We then explore the issue of minimal assumptions required, and show that one-way trapdoor functions are necessary to achieve highly scalable, robustly secure solutions. We then relax the requirement of unlinkable anonymity, and consider scalable solutions that are provably secure and for which the loss of privacy is minimal.
In vivo optical imaging of integrin αV-β3 in mice using multivalent or monovalent cRGD targeting vectors (2007)

In conclusion, we demonstrated that Cy5-RAFT-c(-RGDfK-)4 was indeed binding to the alphaVbeta3 receptor and with an improved activity as compared to its monomeric analog, confirming the interest of using multivalent ligands. Intravenous injection of Cy5-RAFT-c(-RGDfK-)4 in this novel pair of HEK293(beta3) and HEK293(beta1) tumors, provided tumor/skin ratio above 15. Such an important contrast plus the opportunity to use the HEK293(beta1) negative control cell line are major assets for the community of researchers working on the design and amelioration of RGD-targeted vectors or on RGD-antagonists.

A further experimental study has been made of the efficiency of separation of ${\mathrm{He}}^{3}$ from mixtures of ${\mathrm{He}}^{3}$ and ${\mathrm{He}}^{4}$ in a method making use of the "internal convection" process in superfluid liquid helium. It is shown that the method is capable of removing all the ${\mathrm{He}}^{3}$ in mixtures with an original ${\mathrm{He}}^{3}$/${\mathrm{He}}^{4}$ abundance of ${10}^{\ensuremath{-}2}$ percent in a period of about five minutes with a power input of 13 milliwatts. The efficiency of the method as a function of power input is also studied and comparison is made with Kapitza's measurements on the "latent heat" of superfluid atoms.
Aromatization of light naphtha fractions on zeolites 1: Kinetic model (2003)

On the basis of analyzing kinetic experimental data performed in laboratory integral reactors a lumping kinetic model of the "Zeoforming" process was developed. A reaction scheme of the lumped components was proposed, that was adapted to the technological requirements. The reaction rate constants and activation energies were estimated, that are valid for certain feed compositions. The model is intended for further modeling and optimization of the process.
Spiropiperidines as high-affinity, selective .sigma. ligands. (1992)

A variety of achiral conformationally restricted spirocyclic piperidines have been prepared in an attempt to investigate the functional role of the central sigma recognition site. All the compounds possessed a lipophilic N-substituent incorporating either a tetralin, indan, or benzocycloheptane skeleton. Their in vitro affinity at the sigma site was assessed in radioligand displacement experiments with guinea pig cerebellum homogenates using the sigma-specific radioligand [3H]-N,N'-di-o-tolylguanidine ([3H]-DTG, [3H]-6). A study of the structure-activity relationships identified the N-butyl and N-dimethylallyl substituents as the optimum groups for high affinity and selectivity at the sigma site (e.g., 3,4-dihydro-1'-(3-methylbut-2-enyl)spiro[1H-indene-1,4'-piperidine ] (48), pIC50 = 8.9 vs [3H]-6 and greater than 10,000-fold selective over the dopamine D2 receptor). Such compounds are amongst the highest affinity sigma ligands reported to date, with excellent selectivity over the dopamine D2 receptor, and may serve as a useful tool for exploring the physiological role of the sigma site.

Face liveness detection based on texture and frequency analyses (2012)

This paper proposes a single image-based face liveness detection method for discriminating 2-D paper masks from the live faces. Still images taken from live faces and 2-D paper masks were found to bear the differences in terms of shape and detailedness. In order to effectively employ such differences, we exploit frequency and texture information by using power spectrum and Local Binary Pattern (LBP), respectively. In the experiments, three liveness detectors utilizing the power spectrum, LBP, and fusion of the two were trained and tested with two databases which consist of images taken from live and four types of 2-D paper masks. One database was acquired from a web camera while the other was from the camera on the automated teller machine. Experimental results show that the proposed methods can efficiently classify 2-D paper masks and live faces.
Chronic Parasympathetic Sectioning Decreases Regional Cerebral Blood Flow during Hemorrhagic Hypotension and Increases Infarct Size after Middle Cerebral Artery Occlusion in Spontaneously Hypertensive Rats (1992)

Regional cerebral blood flow (rCBF) during controlled hemorrhagic hypotension (140-20 mm Hg) was assessed 10-14 days after chronic unilateral sectioning of parasympathetic and/or sensory fibers innervating pial vessels in spontaneously hypertensive rats (SHR). rCBF was measured in the cortical barrel fields bilaterally by laser Doppler blood flowmetry. Immunohistochemistry of middle cerebral artery (MCA) whole mount preparations was used to verify the surgical lesion. During hemorrhagic hypotension, rCBF was equivalent on the two sides in shams, after selective sensory denervation, or in parasympathetically sectioned animals exhibiting small decreases (less than or equal to 30%) in immunoreactive vasoactive intestinal peptide (VIP)-containing fibers. After chronic parasympathetic denervation, decreases in perfusion pressure were accompanied by greater reductions in rCBF on the lesioned side; changes in vascular resistance were also attenuated on that side. The rCBF response to hypercapnia (PaCO2 50 mm Hg), however, was symmetrical and robust. To examine the effects of impaired neurogenic vasodilation on the pathophysiology of cerebral ischemia, infarct size was measured 24 h following tandem MCA occlusion in denervated animals. Infarction volume was larger after selective parasympathetic sectioning (sham, 156 +/- 27 vs. 196 +/- 32 mm3, respectively) but only in those denervated animals demonstrating greater than or equal to 40% decrease in immunoreactive VIP-containing fibers within the ipsilateral MCA. Lower than expected blood flow/perfusion pressure in the cortex distal to an occluded blood vessel may relate the observed blood flow responses to the occurrence of larger cortical infarcts in parasympathetically denervated animals. If true, the findings suggest a novel role for neurogenic vasodilation in the pathophysiology of cerebral ischemia and in rCBF regulation within the periinfarction zone.

Coordinate interactions of Csk, Src, and Syk kinases with αIIbβ3 initiate integrin signaling to the cytoskeleton (2002)

Integrins regulate cell adhesion and motility through tyrosine kinases, but initiation of this process is poorly understood. We find here that Src associates constitutively with integrin αIIbβ3 in platelets. Platelet adhesion to fibrinogen caused a rapid increase in αIIbβ3-associated Src activity, and active Src localized to filopodia and cell edges. Csk, which negatively regulates Src by phosphorylating Tyr-529, was also constitutively associated with αIIbβ3. However, fibrinogen binding caused Csk to dissociate from αIIbβ3, concomitant with dephosphorylation of Src Tyr-529 and phosphorylation of Src activation loop Tyr-418. In contrast to the behavior of Src and Csk, Syk was associated with αIIbβ3 only after fibrinogen binding. Platelets multiply deficient in Src, Hck, Fgr, and Lyn, or normal platelets treated with Src kinase inhibitors failed to spread on fibrinogen. Inhibition of Src kinases blocked Syk activation and inhibited phosphorylation of Syk substrates (Vav1, Vav3, SLP-76) implicated in cytoskeletal regulation. Syk-deficient platelets exhibited Src activation upon adhesion to fibrinogen, but no spreading or phosphorylation of Vav1, Vav3, and SLP-76. These studies establish that platelet spreading on fibrinogen requires sequential activation of Src and Syk in proximity to αIIbβ3, thus providing a paradigm for initiation of integrin signaling to the actin cytoskeleton.

Microchannel Surface Area Enhancement Using Porous Thin Films (2000)

Microchannels having highly enhanced surface area have been fabricated by a thin‐film deposition technique known as glancing angle deposition. Porosimetry and simulation of the microstructures was used to estimate the surface area enhancement of the new microchannels. Two distinct types of microchannels have been created. In the first, a pre‐existing microchannel is coated with a film of deposited at a highly oblique angle. The resulting structure consists of the original channel filled with slanted columns of . An example of this type of channel was estimated by porosimetry to have surface area of . The second microchannel type is produced by lithographic methods and consists of films of with helical microstructure bounded by walls of photoresist. Simulation of one example of this type of channel led to an estimate of . This estimate, however, ignores the mesoscopic scale surface roughness of the microstructures. © 2000 The Electrochemical Society. All rights reserved.
A spread spectrum modulation method of forward CDMA channel in cellular systems (2002)

A spread spectrum (SS) modulation method of the forward channel in cellular systems is proposed. This method can be used to improve the transmitting properties of the forward CDMA channel with a given output power at the base station. It can map a number of forward CDMA signals onto a binary signal by orthogonally spreading sequences. The fundamental principle, performance and comparison with conventional SS modulation are discussed here.
Optimal Scheme with Load Forecasting for Demand Side Management (DSM) in Residential Areas (2013)

Utilities around the world have been considering Demand Side Management (DSM) in their strategic planning. The costs of constructing and operating a new capacity generation unit are increasing everyday as well as Transmission and distribution and land issues for new generation plants, which force the utilities to search for another alternatives without any additional constraints on customers comfort level or quality of delivered product. De can be defined as the selection, planning, and implementation of measures intended to have an influence on the demand or customer-side of the electric meter, either caused directly or stimulated indirectly by the utility. DSM programs are peak clipping, Valley filling, Load shifting, Load building, energy conservation and flexible load shape. The main Target of this paper is to show the relation between DSM and Load Forecasting. Moreover, it highlights on the effect of applying DSM on Forecasted demands and how this affects the planning strategies for utility companies. This target will be clearly illustrated through applying the developed algorithm in this paper on an existing residential compound in Cairo-Egypt.
The Neuroanatomies of Schizophrenia (1997)

Schizophrenia is a brain disease whose pathophysiology has escaped detection despite intensive investigation. The failure to delineate the neuroanatomy of schizophrenia is related in part to both the subtle nature of the neuropathological abnormalities and to the failure to address adequately the pathophysiological heterogeneity of schizophrenia. The symptoms of schizophrenia aggregate into relatively independent symptom complexes, which suggests that there may be a distinct neural substrate for each complex. If this is true, then the neuroanatomy of schizophrenia is better addressed as the separate neuroanatomies of symptom complexes. However, the use of symptom complexes to guide future neuroanatomical investigations raises crucial methodological issues, including the differentiation of primary versus secondary symptoms, trait versus state characteristics, and continuous versus categorical variables. Decisive hypothesis testing requires that these issues be addressed in study design.
Twin peaks (2010)

Modern processors are evolving into hybrid, heterogeneous processors with both CPU and GPU cores used for general purpose computation. Several languages such as Brook, CUDA, and more recently OpenCL are being developed to fully harness the potential of these processors. These languages typically involve the control code running on the CPU and the performance-critical, data-parallel kernel code running on the GPUs.

The Nucleotide Sequence of Tomato Black Ring Virus RNA-2 (1986)

Summary The sequence of the 4662 nucleotides [excluding poly(A)] of RNA-2 of tomato black ring virus (TBRV) has been determined. Most of the sequence (4074 nucleotides) encodes a polypeptide of mol. wt. 150000 (150K). The 5′ and 3′ non-coding sequences are 287 and 301 nucleotides in length, differ from the coding sequence in base composition, and contain repeated sequences, some of which resemble oligonucleotides in the 3′ non-coding sequence of M-RNA of cowpea mosaic virus (CPMV). From its amino acid composition, the coat protein of TBRV was tentatively located in the C-terminal third of the 150K polypeptide. The amino acid sequence of the 150K polypeptide immediately N-terminal to the putative coat protein sequence was found to resemble parts of the 30K polypeptides of tobamoviruses and, to a lesser extent, part of the 105K polypeptide translation product of CPMV M-RNA.

Lasing in random media (2003)

Abstract A random laser is a non-conventional laser whose feedback mechanism is based on disorder-induced light scattering. Depending on whether the feedback supplied by scattering is intensity feedback or amplitude feedback, random lasers are classified into two categories: random lasers with incoherent feedback and random lasers with coherent feedback. A brief survey of random lasers with incoherent feedback is presented. It is followed by a review of our recent experimental work on random lasers with coherent feedback, including measurement of the lasing threshold, lasing spectra, emission pattern, dynamical response, photon statistics, speckle pattern and the investigation of relevant length scales. Large disorder leads to spatial confinement of the lasing modes, that is the foundation for the micro random laser. Some theoretical models of random lasers with coherent feedback are briefly introduced. The study of random lasers improves our understanding of the interplay between light localization and coherent amplification.
Quantum Data Locking for Secure Communication against an Eavesdropper with Time-Limited Storage (2015)

Quantum cryptography allows for unconditionally secure communication against an eavesdropper endowed with unlimited computational power and perfect technologies, who is only constrained by the laws of physics. We review recent results showing that, under the assumption that the eavesdropper can store quantum information only for a limited time, it is possible to enhance the performance of quantum key distribution in both a quantitative and qualitative fashion. We consider quantum data locking as a cryptographic primitive and discuss secure communication and key distribution protocols. For the case of a lossy optical channel, this yields the theoretical possibility of generating secret key at a constant rate of 1 bit per mode at arbitrarily long communication distances.
Learning resource registry and discovery system (2004)

Learning resource (LR) is difficult to be managed, interchanged and reused in an e-learning system, because different LR has different format or structure and is stored in different location on the Internet. LR users can't discover the needed LR conveniently because they don't know where it is stored. The authors of this paper define an LR registry and discovery model and implement a learning resource registry and discovery system to solve the problem. The system which is developed based on relative LR specifications and communication protocols stores the standard metadata packaging information and the actual content information of LR and provides query interfaces to LR users so that they can quickly discover the LR they need. To standardize LR, the system also provides a LR processing tool for LR developers to create standardized LR. The core idea of the LR registry and discovery system is "store in different places, but manage in one place; register once, discover anywhere ".
Reconfigurable Four-Component Molecular Switch Based on pH-Controlled Guest Swapping (2007)

The four-component ensemble comprising CB[6], beta-CD, and guests 1 and 2 forms complexes CB[6].1H+ and beta-CD.2 at pH < 7 but swaps partners forming complexes CB[6].2 and beta-CD.1 at pH > 13. The intermolecular nature of the switching process suggests application as a basis for stimuli-responsive reconfigurable systems.
Incremental all pairs similarity search for varying similarity thresholds (2009)

All Pairs Similarity Search (APSS) is a ubiquitous problem in many data mining applications and involves finding all pairs of records with similarity scores above a specified threshold. In this paper, we introduce the problem of Incremental All Pairs Similarity Search (IAPSS), where APSS is performed multiple times over the same dataset by varying the similarity threshold. To the best of our knowledge, this is the first work that addresses the IAPSS problem. All existing solutions for APSS perform redundant computations by invoking APSS independently for each threshold value.
Intraocular Tissue Plasminogen Activator in a Rabbit Model of Traumatic Hyphema (1991)

Tissue plasminogen activator was used to evaluate the clearance of traumatic hyphema in a rabbit model. A neodymium-YAG laser was used to disrupt iris vessels, creating a traumatic hyphema. Tissue plasminogen activator (1800 IU/0.1 mL) was injected into the anterior chamber 24 hours after creation of the hyphema. Two control groups (one receiving balanced salt solution and one receiving no treatment) were used for comparison. A multivariate analysis of covariance indicated that the greatest difference in hyphema clearance between the groups occurred at days 3, 4, and 5. Five days after tissue plasminogen activator treatment, the mean size of the clot remaining in the anterior chamber was 27% of that of the original hyphema. In control eyes, almost 60% of the original clot remained at day 5. Treatment of animals with tissue plasminogen activator doses of 5000 IU and 10,000 IU produced a substantial increase in repeated bleeding episodes in our rabbit model. We concluded that although the use of tissue plasminogen activator in our rabbit model of traumatic hyphema significantly improved clearance of blood from the anterior chamber, the remaining clot was of such size that the clinical benefit was questionable.
