Efficient hardware implementations of brw polynomials and tweakable enciphering schemes (2011)

A new class of polynomials was introduced by Bernstein (Bernstein 2007) which were later named by Sarkar as BernsteinRabin-Winograd (BRW) polynomials (Sarkar 2009). For the purpose of authentication, BRW polynomials offer considerable computational advantage over usual polynomials: (m - 1) multiplications for usual polynomial hashing versus ⌊m/2⌋ multiplications and ⌈log <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> m⌉ squarings for BRW hashing, where m is the number of message blocks to be authenticated. In this paper, we develop an efficient pipelined hardware architecture for computing BRW polynomials. The BRW polynomials have a nice recursive structure which is amenable to parallelization. While exploring efficient ways to exploit the inherent parallelism in BRW polynomials we discover some interesting combinatorial structural properties of such polynomials. These are used to design an algorithm to decide the order of the multiplications which minimizes pipeline delays. Using the nice structural properties of the BRW polynomials we present a hardware architecture for efficient computation of BRW polynomials. Finally, we provide implementations of tweakable enciphering schemes proposed in Sarkar 2009 which use BRW polynomials. This leads to the fastest known implementation of disk encryption systems.
D2D Relay Selection Based on Joint Fuzzy and Entropy Theories With Social Similarity (2018)

The employment of social similarity (SS) aware device-to-device (D2D) user equipment (UE)-to-network (UE-NW) relay helps to improve system capacity and UEs' accessability to the evolved Node B (eNB), where a crucial aspect is the design of the relay helper UE (HUE) selection process. However, few existing studies jointly consider the diverse impacts from various design criteria on the performance of HUE selection. In this paper, we formulate the SS-aware D2D UE-NW relay selection (RS) issue as a multiobjective binary integer linear programming (MOBILP) problem under the constraints of several criteria. Then, we propose a new two-stage D2D UE-NW selection scheme. Specifically, a joint algorithm exploiting the intuitionistic fuzzy analytic hierarchy process and the entropy weight generation method is designed for stage one, which provides both subjective and objective preferences for assisting decision making. In stage two, with the constructed decision weights, the MOBILP can be transformed to a simpler binary integer linear programming problem and thus be solved distributively through an efficient message passing method. Based on realistic social data traces, our simulation results validate the benefits of the proposed two-stage scheme, which ensures high system performances in terms of throughput, fairness and energy efficiency.

Hole Contacts on Transition Metal Dichalcogenides: Interface Chemistry and Band Alignments (2014)

MoOx shows promising potential as an efficient hole injection layer for p-FETs based on transition metal dichalcogenides. A combination of experiment and theory is used to study the surface and interfacial chemistry, as well as the band alignments for MoOx/MoS2 and MoOx/WSe2 heterostructures, using photoelectron spectroscopy, scanning tunneling microscopy, and density functional theory. A Mo(5+) rich interface region is identified and is proposed to explain the similar low hole Schottky barriers reported in a recent device study utilizing MoOx contacts on MoS2 and WSe2.
Author reply (2003)

We thank the authors for their interest in our manuscript1 and appreciate the opportunity to respond. We correlated morphologic features and immunohistochemical expression in a cohort of patients with T1 and T2 multicentric breast carcinomas to investigate whether these tumors represent intramammary spread of a single clone of tumor cells with similar antigenic expression or multiple independent primary tumors with different phenotypes. Our question was more than an academic exercise, as we re-evaluated the current practice in our institution of performing immunohistochemical analysis on patients' individual, separate invasive tumors. We found near identical immunohistochemical results in the early multicentric carcinomas we studied, with the prognostic and predictive breast biomarkers supporting the mechanism of clonal growth and/or intramammary spread of a single carcinoma. Contrary to Teixeira et al.'s supposition that we are not aware that molecular and genetic analysis has been performed in attempts to further evaluate the pathogenesis and biology of multicentric breast carcinomas, students of this conundrum are faced with a body of disparate molecular literature that supports both clonally derived synchronous tumors and independent primaries. In fact, in their own words, the authors conclude that existing data is limited.2 The suggestion by the authors to use the clinical terminology multicentric only when clonality has been established is not clinically applicable. Various treatment decisions are made daily in patients with multifocal and multicentric breast cancer that could not wait until molecular confirmation of clonality. We agree with Teixeira et al. that the majority of malignant breast tumors are invasive ductal carcinomas, not otherwise specified, and that is why, in addition to tumor classification, we evaluated traditional histologic parameters, including nuclear grade, presence of in situ carcinoma, lymphovascular invasion, and the tumor's immunohistochemical profile, in attempts to classify whether the tumors in our cohort represented intramammary spread of a clone of tumor cells or multiple independent primaries with different phenotypic expression. These aforementioned morphologic criteria are currently readily available to the practicing pathologist. Our conclusion remains that further study is necessary, and that is why we are in the process of studying our group of multicentric breast carcinomas using available molecular techniques in the quest to understand the genesis of multifocal and multicentric breast neoplasia.

GENETIC AND CHEMICAL VARIABILITY OF WILD RED RASPBERRY (RUBUS IDAEUS L.) GROWING IN POLAND (2010)

The aim of this investigation was to determine the genetic and chemical variability of raspberry growing wild in Poland. HPLC was applied for determination of phenolic compounds. The RAPD analysis indicated genetic variability of investigated populations. Chemical analysis revealed differences in the total content of flavonoids, phenolic acids and tannins in the leaves and roots. Flavonoids, namely quercetin, hyperoside, rutin, kaempferol, and isorhamnetin derivatives (isorhamnetin-3-glucoside and isorhamnetin-3-rutinoside) were found only in the leaves. Five phenolic acids were also identified, i.e., caffeic, chlorogenic, ellagic, rosmarinic and gentisic acids. Roots of red raspberry were richer in phenolic acids than leaves.
Untersuchung des Einflusses von Sulfaten auf das System CaO-SiO2-Al2O3-K2O-H2O mittels Wärmeflusskalorimetrie und in-situ Neutronenbeugung unter hydrothermalen Bedingungen (2005)

Untersuchung des Einflusses von Sulfaten auf das System CaO-SiO&lt;sub&gt;2&lt;/sub&gt;-Al&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;-K&lt;sub&gt;2&lt;/sub&gt;O-H&lt;sub&gt;2&lt;/sub&gt;O mittels Wärmeflusskalorimetrie und in-situ Neutronenbeugung unter hydrothermalen Bedingungen\n\nPorenbeton besteht aus den Rohstoffen Sand, Zement, Branntkalk, Wasser und\nAluminiumpulver (zur Porosierung). Zusätzlich werden Sulfatträger zur Verbesserung der\nphysiko-mechanischen Eigenschaften Druckfestigkeit und Schwindung eingesetzt.\nZiel dieser Arbeit war es, die Wirkung von Sulfat bzw. verschiedener Sulfate in der\nPorenbetonproduktion festzustellen und mögliche Reaktionsmechanismen aufzuzeigen.\nAufgrund des Produktionsablaufs ergaben sich drei Abschnitte, die betrachtet worden sind:\n1. Der Zeitraum vor der hydrothermalen Härtung ist durch die Löschreaktion des\nBranntkalkes und die (nicht vollständig ablaufende) Zementhydratation geprägt.\nDie Löschreaktion von gebranntem Kalk wird verzögert durch:\n&lt;ul&gt;\n&lt;li&gt;Erhöhung der Kalkbrenntemperatur (und/oder –dauer)&lt;/li&gt;\n&lt;li&gt;Zusatz von Sulfatträgern (Verzögerung steigt mit der Sulfatlöslichkeit)&lt;/li&gt;\n&lt;li&gt;Zusatz von Zement&lt;/li&gt;\n&lt;/ul&gt;\n\n2. Während der hydrothermalen Härtung konnte die Phasenentwicklung mittels\nNeutronenbeugung kontinuierlich verfolgt werden.\nSulfate erniedrigen die Geschwindigkeit der Reaktion von Ca(OH)2 mit SiO2. Die\nhydrothermale Reaktion ist zunächst lösungskontrolliert (Bildung amorpher CSH-Phasen)\nund wird zunehmend durch Diffusionsprozesse beeinflusst (kristalline CSH-Phasen\nentstehen). Sulfate scheinen den ansonsten kontinuierlichen Übergang zwischen\namorphen und kristallinen CSH-Phasen für einen Zeitraum von ca. 30 min. zu\nunterbrechen.\n3. Sulfate erhöhen die Druckfestigkeit und senken die Schwindung des Produkts\nPorenbeton. Neben diesen positiven Einflüssen kommt es jedoch auch zu unerwünschten\nNebenerscheinungen: Die Wärmeleitfähigkeit und die Menge eluierbaren Sulfats steigen.\nEin hoher Alkaligehalt fördert die Sulfat-Eluierbarkeit aus dem Porenbeton.
In vitro autoradiography of serotonin 5‐HT2A2C receptor‐activated G protein: Guanosine‐5′‐(γ‐[35S]thio)triphosphate binding in rat brain (2000)

Agonist activation of G protein-coupled receptors induces an increase in the binding of guanosine 5′-(γ-[35S]thio)triphosphate ([35S]GTPγS); this increase in binding has been used as a tool to investigate receptor interaction with the heterotrimer guanine nucleotide-binding regulatory protein (G protein). The present study uses agonist-stimulated [35S]GTPγS binding to characterize serotonin 5-HT2A/2C receptors in rat brain membrane fractions and demonstrate the anatomical localization of the receptors by in vitro autoradiography on slide-mounted sections. The stimulatory effect of the agonist [1-(2,5-dimethoxy-4-iodophenyl)]-2 aminopropane (DOI) is compared to that of serotonin (5-HT). Autoradiography revealed a similar localization of DOI- and 5-HT-stimulated binding of [35S]GTPγS in distinct areas of prefrontal and parietal cortex, consistent with previously reported 5-HT2A receptor distribution. Specific binding was demonstrated in the frontal and parietal cortex, medial prefrontal, and cingular and orbital-insular areas as well as in the hippocampal formation, septal areas, the nucleus accumbens, and the choroid plexus. MDL 100105, a specific 5-HT2A antagonist, and ketanserin, an antagonist of 5-HT2A/2C receptors, blocked DOI stimulation in all labeled areas, whereas 5-HT stimulation was only partially blocked (70–80%). A small but significant inhibition was observed with the specific antagonist of 5-HT2C/2B, SB 206553. This autoradiographic technique provides a useful tool for measuring in situ changes in specific receptor–Gq protein coupling in anatomically discrete brain regions, under physiological and pathological conditions.

Ist die18F-FDG-PET zum Monitoring der palliativen photodynamischen Therapie von nichtresektablen Klatskin-Tumoren geeignet? (2005)

PDT does not effect a relevant reduction of tumour mass in non-resectable hilar cholangiocarcinoma. However, PDT leads to a significant reduction of cholestasis. If (18)F-FDG-PET is suitable for monitoring the effect of new palliative therapeutic approaches, like brachytherapy, the use of modern chemotherapeuticals, COX-2 and receptor-tyrosine kinase inhibitors, perhaps also in combination with PDT, has to be further investigated.
Heterogeneously Catalyzed Epimerization of Menthol Stereoisomers – An Instructive Example to Account for Diffusion Limitations in Complex Reaction Networks (2008)

Abstract The heterogeneously catalyzed epimerization of menthol stereoisomers is an important step in the synthesis of (–)‐menthol by the Haarmann and Reimer process. For an accurate design of a technical reactor, the intrinsic kinetics as well as pore diffusion limitations have to be taken into account. The epimerization consists of a complex reaction network and so a simple approach using effectiveness factors based on Thiele moduli is not possible. In this work, a method is presented to simultaneously calculate the change in concentrations in the bulk phase as well as within the porous particles with time (fixed bed reactor) or local position (batch reactor). A commercially available numerical software was used to solve the differential equations.
Online assessment of sensing performance in experimental spectrum sensing platforms (2014)

Dynamic Spectrum Access aims at exploiting underutilized frequency bands towards improving wireless network performance. In this context, spectrum sensing is employed, in order to monitor spectrum occupancy and drive appropriate adaptation decisions. Researchers in the field primarily evaluate proposed sensing approaches in terms of detection accuracy and efficiency of free spectrum utilization. In this work, we focus on online assessment of spectrum occupancy with respect to sensing delay and energy efficiency. Evaluation of spectrum sensing methods with respect to these two metrics is rather lagging in recent experimental developments. The first is related to the latency induced by the spectrum sensing process and its impact on sensing efficiency, which is tightly connected to the resulting performance of the cognitive solution. On the other hand, energy consumption is considered as a crucial issue in all types of wireless communications. Therefore, it is important to extend existing testbed experimentation tools and develop new ones, in order to equip cognitive testbeds with such advanced monitoring capabilities. To this aim, we integrated the proposed monitoring procedure with the experimentation tools of the CREW testbed federation. In order to demonstrate the applicability of our framework, we experimentally validate the performance of four different sensing platforms, as well as a real-time spectrum sensing engine that implements parallel processing on software defined radios, in terms of the aforementioned metrics.
PiggyBac Transposon-based Inducible Gene Expression In Vivo After Somatic Cell Gene Transfer (2009)

Somatic cell gene transfer has permitted inducible gene expression in vivo through coinfection of multiple viruses. We hypothesized that the highly efficient plasmid-based piggyBac transposon system would enable long-term inducible gene expression in mice in vivo. We used a multiple-transposon delivery strategy to create a tetracycline-inducible expression system in vitro in human cells by delivering the two genes on separate transposons for inducible reporter gene expression along with a separate selectable transposon marker. Evaluation of stable cell lines revealed 100% of selected clones exhibited inducible expression via stable expression from three separate transposons simultaneously. We next tested and found that piggyBac-mediated gene transfer to liver or lung could achieve stable reporter gene expression in mice in vivo in either immunocompetent or immune deficient animals. A single injection of piggyBac transposons could achieve long-term inducible gene expression in the livers of mice in vivo, confirming our multiple-transposon strategy used in cultured cells. The plasmid-based piggyBac transposon system enables constitutive or inducible gene expression in vivo for potential therapeutic and biological applications without using viral vectors.
The Thyroid Accumulation, Oxidation and Metabolic Fate of35S—Methimazole in the Rat (1972)

35S—Methimazole (MMI) was given ip to rats and the tissue distribution of radioactivity, thyroid metabolism and excretion studied over a period of 4 days. An accumulation of radioactivity and of unmetabolised methimazole was found in the thyroid, whereas the radioactivity disappeared rapidly in all other tissues studied. A tissue/plasma (T/P) ratio of radioactivity of 88.6 was demonstrated in the thyroid 12 hr after administration of a single dose of 35S—MMI with a T/P ratio of 2.1 and 1.7 in kidney and liver, respectively. All other tissues had a T/P ratio of less than one. TLC and liquid scintillation analysis of plasma and of thyroid homogenates showed a T/P ratio for 35S—MMI of 2.0 at 1 hr after the dose, rising to 25.5 after 8 hr. The methimazole was mainly oxidised to sulphate in the thyroid. TLC of plasma showed the presence of three compounds; methimazole, sulphate and protein bound radioactivity. Most of the radioactivity was excreted by the kidneys (the majority in the first 24 hr) with only 7.9% of the dose present in the feces. Six radioactive compounds were found in the urine: methimazole, sulphate, a highly polar compound, and three minor unknown compounds.(Endocrinology91: 747, 1972)

Haptic information displays for computer-assisted surgery (2003)

We propose the use of robotic and haptic technology to develop haptic information displays for computer-assisted surgery applications. Such devices provide force and/or tactile feedback to a surgeon to communicate information that is difficult or impossible to communicate via a graphical display alone. Haptic information displays differ from autonomous robots and teleoperators used in surgical applications, and have different requirements than the haptic devices designed for training and simulation of surgical procedures. A haptic information display based on Barrett Technology's Whole-Arm Manipulator is introduced and early experiments for two different classes of medical applications are discussed. This new application area raises open research questions in the areas of haptic robotic systems and human machine interaction.
Private Claims and Public Resources (2016)

Let us begin with a postulate. A productive saltwater marsh is severely damaged by a human-caused environmental calamity. One-third of the area is a federal wildlife refuge, one-third is a state wildlife area, and one-third is owned by a private hunting club. Migratory waterfowl are killed and stop using the area. Resident wildlife species also suffer. Shellfish beds are poisoned. Associated water pollution causes fish to die, and the marsh ceases to support juvenile fish that would eventually grow to populate areas hundreds of miles away. The whole area acquires a deathly look. Most of the affected resources are public resources, those owned or managed by governments for the benefit of the citizenry. Nonetheless, there are substantial private interests in these public resources. An array of prospective plaintiffs steps forward to seek damages. The federal government claims damages to its upland acreage and the waterfowl, while the state claims damages to uplands, submerged lands, fish, shellfish and wildlife. The hunting club also claims damages for its interests in lands, fish, and wildlife. A local commercial fisherman claims damages to the fish and shellfish. An adjacent landowner who has subdivided and is selling his land as Marshview Estates sues, and so do a national sport fish ing association, a national duck hunters' organization, and various environmental organizations. All are suffering, or claim to be suffering, from the damage inflicted on the environment. The law must separate these claims and ensure that each plaintiff is treated appropriately and fairly, without requiring the tortfeasor to pay more than is warranted. This hypothetical case presents the basic issue: When and how can private interests recover damages or bring actions on behalf of injured public resources? Private actions regarding public resources fall into two primary categories: actions for private relief arising from damage to public resources, and actions by private parties on behalf of public resources. Claims brought by the commercial fisherman, the hunting club, and the adjacent landowner are examples of the first category. Such actions for private relief often arise from still applicable common-law rules and principles. However, these rules have been affected by an array of statutes that sometimes preempt traditional claims or offer expanded measures of damages. Citizens suits by the various organizations against the responsible party are the classic example of the second type of action. Actions on behalf of the public interest have historically arisen from common-law principles such as the public trust doctrine. In recent years, however, these actions have been primarily based on rights and remedies created by the legion of environmental statutes enacted since 1969. Trends affecting common-law actions, the effect of new statutes, the expansion of recognized damages, and emerging issues are discussed below.
Electrochemical behavior of Cu(II)-poly(4-vinylpyridine) complexes at the electrode/electrolyte interface (1986)

The electrochemical behavior and electrocatalytic properties of the complex of Cu/sup 2 +/ with poly(4-vinylpyridine) were studied at a pyrolytic graphite electrode. It was shown that not all copper ions of the polymer films are in an electrochemically active state when the process is conducted under nonequilibrium conditions. The counterion type has an important effect of the electrochemical behavior of the polymer film electrode. The complex displays electrocatalytic activity in molecular-oxygen electroreduction in neutral buffer solutions; the activity depends on the degree of saturation of the polymer film with copper ions.
A Cationic Magnesium-Based Dithiolene Radical (2022)

Magnesium-based dithiolene radical adduct (6•), the first Group 2 element based dithiolene radical, was synthesized via Ph3C+[B(C6F5)4]−-mediated one-electron oxidation of the THF-solvated neutral magnesium dithiolene complex (5). Single-crystal X-ray diffraction analysis reveals that 6• exists as a magnesium-based dithiolene radical cation/[B(C6F5)4]− anion pair. While electron paramagnetic resonance (EPR) and computations indicate the predominantly dithiolene ligand-based radical character of 6•, the weak satellite feature of the EPR spectrum of 6• originates from an admixture of the 25Mg isotope (I = 5/2) with a natural abundance of ca. 10%. The redox properties of 6• were explored using cyclic voltammetry.
Long-Term Prognosis of Acute Pulmonary Oedema — An Ominous Outcome (2000)

Most patients with APOE in this study are elderly, and have IHD, hypertension, diabetes and a previous history of APOE. The overall mortality is high (in-hospital, 12%: 1-year, 40%). Left ventricular dysfunction was associated with high in-hospital mortality, but not with long-term prognosis.
