LTE security, protocol exploits and location tracking experimentation with low-cost software radio (2016)

The Long Term Evolution (LTE) is the latest mobile standard being implemented globally to provide connectivity and access to advanced services for personal mobile devices. Moreover, LTE networks are considered to be one of the main pillars for the deployment of Machine to Machine (M2M) communication systems and the spread of the Internet of Things (IoT). As an enabler for advanced communications services with a subscription count in the billions, security is of capital importance in LTE. Although legacy GSM (Global System for Mobile Communications) networks are known for being insecure and vulnerable to rogue base stations, LTE is assumed to guarantee confidentiality and strong authentication. However, LTE networks are vulnerable to security threats that tamper availability, privacy and authentication. This manuscript, which summarizes and expands the results presented by the author at ShmooCon 2016 \cite{jover2016lte}, investigates the insecurity rationale behind LTE protocol exploits and LTE rogue base stations based on the analysis of real LTE radio link captures from the production network. Implementation results are discussed from the actual deployment of LTE rogue base stations, IMSI catchers and exploits that can potentially block a mobile device. A previously unknown technique to potentially track the location of mobile devices as they move from cell to cell is also discussed, with mitigations being proposed.
Tightly Synchronized Distributed Measurement and Event Triggers (2008)

In this paper we describe the principles, design and implementation of a method to reliably perform tightly synchronized data acquisition and event triggering in a distributed control system. In parallel to event triggers, our timing system facilitates maintaining tightly synchronized clocks to achieve high quality timestamps which can be tailored to the event triggers if wanted. We introduce concept of priority-based clocks to handle timing hardware failures and to provide flexibility and commonality of time management in a large scale distributed control system. Contribution of this work is mainly: 1) Integration of our hardware-assisted data timestamping method into a control and data acquisition framework 2) Priority-based clock mechanism which overcomes hardware clock failures and allows computing nodes continue monitoring and collecting distributed events with a coarser precision. This framework allows us to build a tightly synchronized distributed control and measurement system without mandating the use of any special hardware.
Influence of Block Copolymers on the Microbiological Leaching of Pyrites by Discontinuous Operation (1984)

Article Influence of Block Copolymers on the Microbiological Leaching of Pyrites by Discontinuous Operation was published on March 1, 1984 in the journal Tenside Surfactants Detergents (volume 21, issue 2).
Heterogeneity of the breakpoint in the ABL gene in cases with BCR/ABL transcript lacking ABL exon a2. (1994)

We report cases with a variant BCR/ABL mRNA expression lacking ABL exon a2 sequences. Two of these cases showed major breakpoint cluster region (BCR) exon 3 (b3) and ABL exon 3 (a3) junction (b3/a3), while the other case showed minor BCR exon 1 (e1) and a3 junction (e1/a3). One of the two cases with b3/a3 junction and the case with e1/a3 junction were diagnosed as acute lymphoblastic leukemia, and the remaining case with b3/a3 junction was chronic myeloid leukemia. Two of these cases, however, were found to have a breakpoint in the ABL gene outside of the intron between exons a2 and a3, probably 5' upstream of exon a2, suggesting that the BCR exon was spliced to ABL exon a3. These findings differ from those previously reported, in which the breakpoints in the ABL gene were between exons a2 and a3, and indicate a novel mechanism for the deletion of ABL exon a2 sequences in the formation of a variant BCR/ABL fusion transcript. The significance of the finding that a part of the SH3 region of ABL protein is missing in some Philadelphia chromosome-positive leukemias is discussed in reference to the cases reported previously.
Synthesis, polymerization, and copolymerization of lactam‐substituted styrenes (1982)

Abstract Four new substituted styrene derivatives carrying lactam rings (2‐pyrrolidone or 2‐piperidone) in para position have been synthesized, namely 4‐(2‐oxo‐3‐methylene‐pyrrolidinyl)styrene, 4‐(2‐oxo‐3‐methylene‐piperidinyl)styrene, 4‐( p ‐styryl)‐2‐pyrrolidone, and 4‐( p ‐styryl)‐2‐piperidone. Their homopolymerization and copolymerization with styrene, methyl methacrylate, and acrylic acid have been considered. By ring opening of the side lactam groups, the homopolymers are transformed into the corresponding poly aminocarboxylic acids.
Proton‐driven sucrose symport and antiport are provided by the vacuolar transporters SUC4 and TMT1/2 (2011)

The vacuolar membrane is involved in solute uptake into and release from the vacuole, which is the largest plant organelle. In addition to inorganic ions and metabolites, large quantities of protons and sugars are shuttled across this membrane. Current models suggest that the proton gradient across the membrane drives the accumulation and/or release of sugars. Recent studies have associated AtSUC4 with the vacuolar membrane. Some members of the SUC family are plasma membrane proton/sucrose symporters. In addition, the sugar transporters TMT1 and TMT2, which are localized to the vacuolar membrane, have been suggested to function in proton-driven glucose antiport. Here we used the patch-clamp technique to monitor carrier-mediated sucrose transport by AtSUC4 and AtTMTs in intact Arabidopsis thaliana mesophyll vacuoles. In the whole-vacuole configuration with wild-type material, cytosolic sucrose-induced proton currents were associated with a proton/sucrose antiport mechanism. To identify the related transporter on one hand, and to enable the recording of symporter-mediated currents on the other hand, we electrophysiologically characterized vacuolar proteins recognized by Arabidopsis mutants of partially impaired sugar compartmentation. To our surprise, the intrinsic sucrose/proton antiporter activity was greatly reduced when vacuoles were isolated from plants lacking the monosaccharide transporter AtTMT1/TMT2. Transient expression of AtSUC4 in this mutant background resulted in proton/sucrose symport activity. From these studies, we conclude that, in the natural environment within the Arabidopsis cell, AtSUC4 most likely catalyses proton-coupled sucrose export from the vacuole. However, TMT1/2 probably represents a proton-coupled antiporter capable of high-capacity loading of glucose and sucrose into the vacuole.
Desconfiança política na América Latina (2005)

Este trabalho examina o contexto, as causas e as conseqüências da desconfiança nos políticos no atual período democrático da América Latina. Em termos de contexto, demonstramos que a confiança muito baixa nos políticos da América Latina é meramente um dos aspectos de uma síndrome de baixa confiança generalizada. Em termos das causas da desconfiança, examinamos três características proeminentes do desenvolvimento democrático nos últimos quinze anos: fraco desempenho econômico da maioria das novas democracias da região, escândalos de corrupção e o uso instrumental das instituições políticas pelos governantes. Em termos de conseqüências, examinamos o apoio fraco e desigual à democracia em toda a região, que parece estar relacionado causalmente com a desconfiança nos políticos. No entanto, evitamos o alarmismo sustentando que esses resultados devem ser contextualizados à luz da citada síndrome de baixa confiança multidimensional da América Latina. Ademais, o reservatório de atitudes autoritárias entre os indivíduos é fragmentário e raramente se expressa de forma coerente na ação política. Além disso, como a pesquisa sobre democracias tanto avançadas como emergentes demonstrou recentemente, os cidadãos estão cada vez mais dispostos a separar suas avaliações dos governantes (com freqüência, negativas) da avaliação da democracia como tipo de regime.
The residual risk of sepsis: modeling the effect of concentration on bacterial detection in two‐bottle culture systems and an estimation of false‐negative culture rates (2007)

Continuing reports of septic reactions after transfusion of culture-tested apheresis PLTs, and frequent single-bottle-positive results when testing with two-bottle systems, suggest appreciable levels of false-negative results with a commercially available bacterial detection system (BacT/ALERT, bioMéreiux) as implemented.
Bayesian Discovery of Threat Networks (2014)

A novel unified Bayesian framework for network detection is developed, under which a detection algorithm is derived based on random walks on graphs. The algorithm detects threat networks using partial observations of their activity, and is proved to be optimum in the Neyman–Pearson sense. The algorithm is defined by a graph, at least one observation, and a diffusion model for threat. A link to well-known spectral detection methods is provided, and the equivalence of the random walk and harmonic solutions to the Bayesian formulation is proven. A general diffusion model is introduced that utilizes spatio-temporal relationships between vertices, and is used for a specific space-time formulation that leads to significant performance improvements on coordinated covert networks. This performance is demonstrated using a new hybrid mixed-membership blockmodel introduced to simulate random covert networks with realistic properties.
Detection of 3-amino-2-oxazolidinone (AOZ), a tissue-bound metabolite of the nitrofuran furazolidone, in prawn tissue by enzyme immunoassay (2004)

Furazolidone, a nitrofuran antibiotic, is banned from use in food animal production within the European Union. Increasingly, compliance with this ban is monitored by use of analytical methods to detect a stable tissue-bound metabolite, 3-amino-2-oxazolidinone (AOZ). Widespread use of furazolidone in poultry and prawns imported into Europe highlighted the urgent need for development of nitrofuran immunoassay screening tests. The first enzyme-linked immunoabsorbant assay for detection of AOZ residues in prawns (shrimps) is now described. Prawn samples were derivatized with o-nitrobenzaldehyde, extracted into ethyl acetate, washed with hexane and applied to a competitive enzyme immunoassay based on a rabbit polyclonal antiserum. Assay limit of detection (LOD) (mean + 3 s) calculated from the analysis of 20 known negative cold and warm water prawn samples was 0.1 microg kg(-1). Intra- and interassay relative standard deviations were determined as 18.8 and 38.2%, respectively, using a negative prawn fortified at 0.7 microg kg(-1). The detection capability (CCbeta), defined as the concentration of AOZ at which 20 different fortified samples yielded results above the LOD, was achieved at fortification between 0.4 and 0.7 microg kg(-1). Incurred prawn samples (n = 8) confirmed by liquid chromatography coupled with tandem mass spectrometry detection to contain AOZ concentrations between 0.4 and 12.7 microg kg(-1) were all screened positive by this enzyme-linked immunoabsorbant assay. Further data are presented and discussed with regard to calculating assay LOD based on accepting a 5% false-positive rate with representative negative prawn samples. Such an acceptance improves the sensitivity of an ELISA and in this case permitted an LOD of 0.05 microg kg(-1) and a CCbeta of below 0.4 microg kg(-1).
Chapter 7: Biomathematical engineering of cell renewal systems: An approach to a biomathematical model of lymphocytopoiesis (1995)

Fundamental principles for the development of a biomathematical model of lymphocytopoiesis are presented in this paper. The first step in this modeling approach is the definition of appropriate anatomical compartments in order to identify dominant locations of lymphocytes in the human body, and the definition of functional compartments in order to model different maturation stages. In the second step these compartment structures are combined, and thus form the basis of a dynamical model consisting of linear differential equations. Cell balance equations are used to derive the biomathematical dynamical model which is presented using the tools of modern systems theory. As a result of intensive discussions between engineers and medical doctors, our model of lymphocytopoiesis consists of six anatomical and six functional compartments. Virtual marking technique plays a key role for the interpretation of the simulation results which are in solid agreement with biological observations. Future work is directed towards implementation of radiation damages in order to meet the final goal, namely, the evaluation of our model against the data derived from a group of chronically irradiated uranium miners.
Optical component coupling using self-written waveguides (2002)

The self-written waveguide is a possible solution to improving the alignment of optical connections. By introducing light from an optical fibre edge to a photosensitive medium, an optical waveguide easily forms under the condition that the refractive index of the exposed medium increases; it gives a hybrid optical component composed of an optical fibre and an optical waveguide without any alignment adjustment. The method is described and experimental results given for multi-mode fibre (MMF) coupling. Self-written waveguides were successfully formed in the gap between two MMFs; the coupling loss was about 0.6 dB for a 500 /spl mu/m gap.

Modeling of GaN based resonant-cavity light-emitting diode (2007)

We extended the theory by Henry [1] to accurately treat the coupling of spontaneous emission noise with microcavity modes. The Green's function method is employed to solve the inhomogeneous wave equation including a Langevin force <i>f</i><sub>&comega;</sub> which accounts for spontaneous emission by carriers at angular frequency &comega;. The optical wave equation is coupled with the self-consistent calculations of the material spontaneous emission rate of quantum well/dot using envelope wavefunction method. Finally the carrier transport equations are solved within the framework of 2D/3D drift-diffusion model implemented in the Crosslight Software package APSYS [2]. The simulation results of a GaN based resonant-cavity light-emitting diode (RC-LED) showed that our models can be used to predict the characteristics of RC-LED.
Research Review (2011)

Getting requirements right is considered the most important and difficult part of the software development process. As organizations and stakeholders become more globally distributed, getting requirements right will pose a greater challenge. Today, organizations are offered a sophisticated array of multimedia meeting systems with video, audio and computer support for remotely specifying requirements. In the context of present day’s global workforce scenario, distributed requirements engineering is now being explored by researchers as well as industry to build an understanding of the dynamics of this highly interactive phase in a globally distributed context. Accordingly, this paper addresses the timely need of reviewing the literature on globally distributed requirements engineering. Findings highlight paucity of literature in this area. Additionally, the paper presents an innovative approach to globally distributed requirements engineering by reviewing the literature on the applicability of agile development approach in a globally distributed setting. Contributing to academic and practitioner literature, the author discusses emerging directions for future research in this area.
Automating software specification, design and synthesis for computer aided control system design tools (2002)

Graphical modeling and programming specifications are becoming increasingly popular due to the need for executable specifications that are easy to understand. In order to fully leverage the advantages of graphical models, it is necessary to provide extensive automation support. Automation can potentially be applied to software design analysis, verification, validation, and automatic code generation. The automation requires a clear and concise definition of the graphical design and implementation specification. A unique approach has been established that permits Computer Aided Control System Design (CACSD) models to be prepared with software design information that is compatible with various commercial software support tools and internally developed tools. The neutral design approach permits implementation decisions to be deferred until late in the development cycle. This permits the optimal target processor, real time operating systems (RTOS), test tools, and automatic code generation tools to be selected once all of the system requirements are known and modeled in the CACSD tool. In order to realize a software implementation, it is critical to establish a mapping between specification and implementation. This paper describes the neutral software design specification approach and how the specification is used in design, testing, and automatic code generation. The paper further discusses tool technology, information representation, synthesis approaches, and automation.
Perovskites in catalysis and electrocatalysis (2017)

Catalysts for chemical and electrochemical reactions underpin many aspects of modern technology and industry, from energy storage and conversion to toxic emissions abatement to chemical and materials synthesis. This role necessitates the design of highly active, stable, yet earth-abundant heterogeneous catalysts. In this Review, we present the perovskite oxide family as a basis for developing such catalysts for (electro)chemical conversions spanning carbon, nitrogen, and oxygen chemistries. A framework for rationalizing activity trends and guiding perovskite oxide catalyst design is described, followed by illustrations of how a robust understanding of perovskite electronic structure provides fundamental insights into activity, stability, and mechanism in oxygen electrocatalysis. We conclude by outlining how these insights open experimental and computational opportunities to expand the compositional and chemical reaction space for next-generation perovskite catalysts.
Denervation and hyperinnervation in the nervous system of diabetic animals. I. The autonomic neuronal dystrophy of the gut (1989)

Peripheral neuropathy is a correlate of experimental diabetes induced in rats by means of a single injection of alloxan. The autonomic and enteric innervation of the gut are profoundly affected in the small intestine of such animals. A complex process of denervation and hyperinnervation of the gut wall of diabetic animals is observed. It was previously reported that the cholinergic parasympathetic innervation of the intestine is markedly reduced. We have found that noradrenergic sympathetic axons hyperinnervate the duodenum of diabetic rats, whereas noradrenaline levels are significantly reduced in the jejunum. The putative enteric neurotransmitter dopamine is also present in higher levels in the duodenum. The intrinsic peptidergic neurons of the gut are deeply affected as well in diabetic rats. Substance P and met-enkephalin content are remarkably reduced throughout the small intestine, whereas vasoactive intestinal polypeptide levels (VIP) are significantly increased in the duodenum. Indeed, immunocytochemical staining of the ileum did reveal hypertrophy of VIP-positive axons in diabetic rats. The intrinsic serotoninergic innervation of the gut is apparently unaffected. Our results indicate that the changes of gut innervation observed in experimental diabetes are consistent with increased content and also likely with hyperinnervation by the neuronal systems involved in smooth muscle relaxation and decreased content and with denervation by those systems with smooth muscle contraction properties. Such a perturbed gut innervation may be responsible of the gastrointestinal dysfunctions that are among the most common complications of diabetes.
