Universally Secure Network Coding with feedback (2016)

In the model of Secure Network Coding, a sender is connected to several receivers by a network, i.e. a directed graph with a single source node and several destination nodes, where each node can perform operations on the values received via the incoming edges and sends the results via the outbound edges. An active adversary controls some of the edges; this means that he can read every symbol transmitted over the edges under his control and replace them with symbols of his choice. The goal of Secure Network Coding is to design protocols that allow transmission of a secret message from the sender to all receivers in a private and reliable way. Classically, only one-way communication (from sender to receivers) has been studied; in this setting, security can be guaranteed as long as the number of edges controlled by the adversary is less than one third of the network connectivity. In this paper, we present a procedure where receivers are allowed to send feedback to the sender; with this feature, security is guaranteed against a stronger adversary: namely, the number of corrupted edges only needs to be smaller than one half of the connectivity. Furthermore, like previous state-of-the-art work on the single-round scenario, our scheme is universal, i.e. it does not require knowledge of the network code.
Anti-phosphocholine hybridoma antibodies. II. Functional analysis of binding sites within three antibody families. (1981)

The present investigation extends our immunochemical characterization of binding site heterogeneity among a large series of monoclonal anti-phosphocholine (PC) antibodies. Hybridoma proteins (HP) from eight genetically distinct strains are included in this study, yet no strain specific characteristics are observed. These HP, as previously shown (5), are divided into three well-defined families based on public or family-specific Id and L chain isotypes characteristic of three PC-binding myeloma proteins: T15, M603, and M511. All antibodies exhibited some degree of inter- or intra-family heterogeneity, or both. Some of this intra-family diversity was reflected by differential reactivity for PC when attached to three different carriers. In spite of this, the specificity profiles for hapten analogues of PC, as measured by hapten inhibition of binding, were the same for all members of the T15 family. Altering the carrier had no effect, thus suggesting that the binding site pocket for PC is essentially preserved, whereas that for carrier is variable. Similar conclusions were reached for most of the M603 HP, although the binding site is different from the T15 HP. The M511 HP stand in sharp contrast to the HP in the other two families because their binding sites exhibit extensive variability. The independence in reactivity for PC and PC plus carrier offers a rational explanation for idiotypic and/or structural heterogeneity within a family. More importantly it suggests interesting strategies for diversification within one group of antibodies.

Transformation of human cells by DNAs ineffective in transformation of NIH 3T3 cells. (1985)

Neonatal human foreskin fibroblasts can be transformed to anchorage-independent growth by transfection with DNAs inefficient in transforming NIH 3T3 cells. Human cells transfected with DNA from GM 1312, a multiple myeloma cell line, or MOLT-4, a permanent lymphoblast line, grow without anchorage at a much higher frequency than do the parental cells and their DNAs can transform human cell recipients to anchorage-independent growth; they have extended but not indefinite life spans and are nontumorigenic. Human fibroblasts are also transformed by DNAs from two multiple myeloma lines that also transform 3T3 cells; however, restriction analysis suggests that different transforming genes in this DNA are acting in the human and murine systems. These results indicate that the human cell transfection system allows detection of transforming genes not effective in the 3T3 system and points out the possibility of detection of additional transforming sequences even in DNAs that do transform murine cells.
Bouldering: an alternative strategy to long-vertical climbing in root-climbing hortensias (2014)

In the Neotropics, the genus Hydrangea of the popular ornamental hortensia family is represented by climbing species that strongly cling to their support surface by means of adhesive roots closely positioned along specialized anchoring stems. These root-climbing hortensia species belong to the nearly exclusive American Hydrangea section Cornidia and generally are long lianescent climbers that mostly flower and fructify high in the host tree canopy. The Mexican species Hydrangea seemannii, however, encompasses not only long lianescent climbers of large vertical rock walls and coniferous trees, but also short 'shrub-like' climbers on small rounded boulders. To investigate growth form plasticity in root-climbing hortensia species, we tested the hypothesis that support variability (e.g. differences in size and shape) promotes plastic responses observable at the mechanical, structural and anatomical level. Stem bending properties, architectural axis categorization, tissue organization and wood density were compared between boulder and long-vertical tree-climbers of H. seemannii. For comparison, the mechanical patterns of a closely related, strictly long-vertical tree-climbing species were investigated. Hydrangea seemannii has fine-tuned morphological, mechanical and anatomical responses to support variability suggesting the presence of two alternative root-climbing strategies that are optimized for their particular environmental conditions. Our results suggest that variation of some stem anatomical traits provides a buffering effect that regulates the mechanical and hydraulic demands of two distinct plant architectures. The adaptive value of observed plastic responses and the importance of considering growth form plasticity in evolutionary and conservation studies are discussed.
Enhanced expression of nuclear factor I/B in oxaliplatin‐resistant human cancer cell lines (2010)

Oxaliplatin is a third-generation platinum drug that has favorable activity in cisplatin-resistant cells. However, the molecular mechanisms underlying oxaliplatin resistance are not well understood. To investigate the molecular mechanisms involved, resistant cell lines were independently derived from colon cancer (DLD1) and bladder cancer (T24) cells. Oxaliplatin-resistant DLD1 OX1 and DLD1 OX2 cell lines were approximately 16.3-fold and 17.8-fold more resistant to oxaliplatin than the parent cell lines, respectively, and had 1.7- and 2.2-fold higher cross-resistance to cisplatin, respectively. Oxaliplatin-resistant T24 OX2 and T24 OX3 cell lines were approximately 5.0-fold more resistant to oxaliplatin than the parent cell line and had 1.9-fold higher cross-resistance to cisplatin. One hundred and fifty-eight genes commonly upregulated in both DLD1 OX1 and DLD1 OX2 were identified by microarray analysis. These genes were mainly involved in the function of transcriptional regulators (14.6%), metabolic molecules (14.6%), and transporters (9.5%). Of these, nuclear factor I/B (NFIB) was upregulated in all oxaliplatin-resistant cells. Downregulation of NFIB rendered cells sensitive to oxaliplatin, but not to cisplatin. Forced expression of NFIB induced resistance to oxaliplatin, but not to cisplatin. Taken together, these results suggest that NFIB is a novel and specific biomarker for oxaliplatin resistance in human cancers.

Postural control without optic flow (2010)

Discrete visual displacement of a room has been shown to cause body sway in adults and cause children to stagger (Lee & Aronson, 1974; Lee & Lishman, 1975). Sinusoidal displacement has been shown to cause body sway at the frequency of the room motion (Dijkstra, et al, 1994). Presumably this effect is due to an attempt to stabilize posture with respect to the external environment. Our experiments tested the idea that visually controlled postural stabilization may occur in the absence of optic flow. To investigate this, we measured postural response to a moving room presented in virtual reality. Subjects viewed either a luminance-defined dioptic environment containing smooth optic flow or a rapidly scintillating random dot cinematogram (SRDC) environment (Julesz, 1971), devoid of any optic flow relating to the task. The SRDC environments consisted of a sequence of random-dot stereograms with single-frame lifetimes, which to each eye appeared as a scintillating dot display of uniform density. Thus, the SRDC stimulus contained no optic flow related to the motion of the room. In both conditions, subjects stood 30 cm. from the wall of a room that oscillated longitudinally at 0.2 Hz. with an amplitude of 10 cm. An optical tracking system measured body sway during exposure to both a moving and stationary (control) room. Spectral analysis of the body motion data revealed significant body sway at the frequency of the visual stimulus (0.2 Hz) for both dioptic and SRDC conditions. During dioptic exposure, room motion produced body sway amplitude that was 5.6 times greater than the control condition. Similarly, SRDC exposure resulted in sway amplitude that was 2.4 times greater than the control. These data suggest that optic flow is not necessary for visual control of posture. Rather, perceived motion regardless of how it is evoked drives postural control.
Thermodynamic properties of hydrochloric acid in dimethylformamide–water mixtures at different temperatures (1971)

The standard potential of the Ag–AgCl electrode has been determined from the e.m.f. of a cell of the type Pt,H2(gas 1 atm)|HCL (m), Me2N·CHO (X), H2O (100 –X)|AgCl, Ag at five different temperatures in the range 5–45 °C. Measurements were made in dimethylformamide–water mixtures [X= 5 and 10%(w/w)] for acid concentrations in the range 0·005–0·2 mol kg–1. The mean activity coefficients of HCl have been calculated. The standard thermodynamic quantities (ΔG°, ΔH°, ΔS°, and ΔCp°) accompanying the transfer of HCl from water to the respective solvent media have been computed from the variations of ΔEN°(the difference in standard e.m.f. between the ordinary water and the mixed solvent on the mole-fraction scale) with temperature. The results have been discussed with respect to the solvent structure and acid–base behaviour on the transfer process.

Chapter Microarrays in Neuroscience (2009)

In the past few years, microarray technology has matured into a commonly used laboratory tool in biomedical research, including neuroscience. A variety of topics in neuroscience have now been investigated using microarray-based approaches. Although the initial microarray publications appeared in the early 1990s, the rst neuroscience microarray study dates to just 1999. To date, several deoxyribonucleic acid (DNA) array studies have been published with a constant and signi - cant increase throughout the years (Figure 18.1). Microarray-based studies in neuroscience encompass neurological, and psychiatric disorders, drug addiction (see later), memory and learning [1,2], and circadian rhythms [3,4]. Arrays have been used to address the topic of human brain evolution comparing the gene expression patterns of Homo sapiens, to those of the close relative Pan troglodytes and other primates (for a review see Ref. [5]).
Antimicrobial activity and beta-lactamase stability of foramidocillin (1986)

Foramidocillin is a 6-alpha-formamido penicillin with a 6-beta-acylureido side chain. The majority of the Enterobacteriaceae were inhibited by less than or equal to 1 microgram of foramidocillin per ml, and Pseudomonas aeruginosa was inhibited by 4 micrograms/ml. Foramidocillin had activity comparable to those of ceftazidime, imipenem, and aztreonam against beta-lactamase-producing members of the Enterobacteriaceae and P. aeruginosa, and it inhibited organisms resistant to piperacillin. Foramidocillin did not inhibit gram-positive species or anaerobic gram-negative bacteria. Foramidocillin was not hydrolyzed by the common plasmid-mediated beta-lactamases TEM-1, TEM-2, OXA-2, PSE-4, and SHV-1, by the chromosomal beta-lactamases P99 of Enterobacter cloacae and K1 of Klebsiella oxytoca, or by the Sabath-Abraham enzyme of P. aeruginosa.
Controlling “Mottness” in a Correlated Electron System via Coherent Vibrational Excitation (2010)

Control of onsite electronic wavefunctions is achieved in the organic conductor (BEDT-TTF)-F2TCNQ by resonant excitation of localized molecular vibrational modes of the BEDT molecule. In this way, the onsite two-particle Coulomb repulsion can be modulated.
The Aging Kidney: Increased Susceptibility to Nephrotoxicity (2014)

Three decades have passed since a series of studies indicated that the aging kidney was characterized by increased susceptibility to nephrotoxic injury. Data from these experimental models is strengthened by clinical data demonstrating that the aging population has an increased incidence and severity of acute kidney injury (AKI). Since then a number of studies have focused on age-dependent alterations in pathways that predispose the kidney to acute insult. This review will focus on the mechanisms that are altered by aging in the kidney that may increase susceptibility to injury, including hemodynamics, oxidative stress, apoptosis, autophagy, inflammation and decreased repair.
M-K medium and postmortem cytologic damage. (1978)

Freshly enucleated rabbit eyes were refrigerated at +4 degrees C under standard eye bank conditions for 2, 6, 9, and 21 days. One group of corneas with a scleral rim were excised and placed in M-K medium, stored for 18, 24, or 48 hr at +4 degrees C; they were then removed, and endothelial cell viability was evaluated with nitroblue tetrazolium. The cells were examined by light microscopy and scanning and transmission electron microscopy. A second group of corneas were similarly obtained and then used as donor corneas from 6 mm transplants. Each recipient rabbit was evaluated daily by slit-lamp biomicroscopy and corneal pachometry. Fourteen days postoperatively, the rabbits were sacrificed, the eyes enucleated, and the excised corneas were evaluated in a fashion similar to those of group 1. M-K medium storage protected the morphology and functional integrity of the rabbit corneal endothelium up to 48 hr beyond moist chamber storage for 2, 6, and 9 days. However, M-K medium appeared to have no such effect on corneas that had been moist chamber--stored for 21 days. These results suggest that some human corneas with a prolonged time from death to moist chamber storage may be utilized for corneal transplantation after further storage in M-K medium.
<sup>51</sup>V Magic Angle Spinning NMR Spectroscopy of Six-Coordinate Lindqvist Oxoanions:  A Sensitive Probe for the Electronic Environment in Vanadium-Containing Polyoxometalates. Counterions Dictate the <sup>51</sup>V Fine Structure Constants in Polyoxometalate Solids (2003)

Geometric and electronic environments of vanadium have been addressed by (51)V magic angle spinning NMR spectroscopy of six-coordinated polyoxometalate solids. (C(4)H(9))(4)N(+) and mixed Na(+)/Cs(+) salts of the Lindqvist-type mono- and divanadium-substituted oxotungstates, [VW(5)O(19)](3-) and [V(2)W(4)O(19)](4-), have been prepared as microcrystalline and crystalline solids. The solid-state NMR spectra reflect the details of the local environment of the vanadium site in these hexametalate solids via the anisotropic quadrupolar and chemical shielding interactions. Remarkably, these (51)V fine structure constants in the solid state are dictated by the nature and geometry of the countercations. Electrostatic calculations of the electric field gradients at the vanadium atoms have been performed. Experimental trends are well reproduced with the simple electrostatic model, and explain the sensitivity of the anisotropic NMR parameters to the changes in the cationic environment at the vanadium site.
A Promising New Energy-Based Fatigue Life Prediction Framework (2005)

An energy-based fatigue life prediction framework has been developed for prediction of axial and bending fatigue life at various stress ratios. The framework for the prediction of fatigue life via energy analysis was developed in accordance with the approach in our previous study which states: the total strain energy dissipated during a monotonic fracture process is a material property that can be determined by measuring the area underneath the monotonic true stress-strain curve. The framework consists of the following two elements: (1) Development of a bending fatigue criterion by observing the total strain energy of the effective volume, which is achieved by computing the total plastic strain energy with consideration of the stress gradient influence through the thickness of a specimen, in the fatigue area, during cyclic loading. A comparison between the prediction and the experimental results from 6061-T6 aluminum specimens was conducted and shows that the new energy-based fatigue criterion is capable of predicting accurate fully reversed bending fatigue life. (2) Development of a new life prediction criterion for axial fatigue at various stress ratios. The criterion was constructed by accounting for both the residual energy dissipated, monotonically, due to the mean stress, and the incorporation of the mean stress effect into the total strain energy density dissipated per cycle. The performance of the criterion was demonstrated by experimental results from 6061-T6 aluminum dog-bone specimens subjected to axial stress at various stress ratios. The comparison shows very good agreement, thus validating the capability of producing accurate fatigue life predictions.

A meteorological data-acquisition system for atmospheric propagation studies (1988)

Instrumentation for studying the propagation of near-millimeter waves has been designed and implemented at 1-mile-long test site in Sandusky, OH. Measurements of the atmospheric structure functions and the transverse wind velocity along the propagation path is accomplished with a custom-built meteorological data-acquisition network consisting of six towers linked together with fiber-optic data lines. Each tower is microprocessor controlled and includes a three-axis anemometer, a Lyman-alpha hydrometer, and a differential temperature probe, with other meteorological parameters obtained at various locations along the path. A modified ISO-OSI reference model is used as the controlling protocol.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Stress dependence of the pocket gap modes in KI:<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msup><mml:mrow><mml:mi mathvariant="normal">Ag</mml:mi></mml:mrow><mml:mrow><mml:mo>+</mml:mo></mml:mrow></mml:msup></mml:mrow></mml:math> (1992)

Far-ir uniaxial-stress experiments reveal the unusual result that the pocket gap modes in KI:${\mathrm{Ag}}^{+}$ couple much more to the fully symmetric (${\mathit{A}}_{1\mathit{g}}$) strain than to the tetragonal (${\mathit{E}}_{\mathit{g}}$) and trigonal (${\mathit{T}}_{2\mathit{g}}$) strains; other modes due to monatomic substitutional defects are found to couple with similar strengths to both ${\mathit{A}}_{1\mathit{g}}$ and ${\mathit{E}}_{\mathit{g}}$ strains. Theoretical calculations based on perturbed breathing-shell-model phonons and a simple anharmonicity model suggest the presence of unusual pressure-induced microscopic displacements in the vicinity of the defect's fourth-nearest neighbors. The coupling coefficients of the pocket gap mode at 86.2 ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$ are measured to be temperature dependent, with the ${\mathit{E}}_{\mathit{g}}$ coefficient actually changing sign at 12 K; such behavior has not been found for other impurity-induced localized modes.
Genetic theraphy for cancer: hurdles remain (2005)

Approved targeted therapies for cancer have to date included small molecule drugs and monoclonal antibodies. Although generally less toxic than standard chemotherapeutics, these agents have had relatively modest single-agent efficacy against the common carcinomas, and tumor resistance universally develops. Advances in cancer therapy will require novel agents with new mechanisms-of-action, multiple modes of cell destruction and synergy with standard treatments. Genetic therapies have the potential to fit this profile.
