Thermodynamic Properties for Solution of Hydrogen in Palladium‐Based Binary Alloys (1995)

Abstract The thermodynamic parameters for solution of hydrogen at infinite dilution and the (a+B) plateau thermodynamic properties for hydrogen absorption at moderate temperatures for a series of Pd‐based f.c.c binary alloys with relatively low solute metal content have been correlated from the viewpoint of whether the alloy lattice is expanded or contracted to parent Pd lattice. Newly determined data for Pd‐Zn, Pd‐Sb, Pd‐Bi, Pd‐Cr, Pd‐Mo and Pd‐Mn alloys are included. When alloys with solute metals in the same groups are compared, the lattice parameters of Pd binary alloys with the 4 d and 5 d transition elements are, in general, larger than those with the 3 d elements. The relative partial molar enthalpy, Δ H 0 H , at infinite dilution becomes more exothermic with an increase of lattice parameter for the lattice‐expanded alloys with the exception of Pd‐Pt alloys. Conversely, for contracted alloys, with the exceptions of Pd‐Li, Pd‐Zn, Pd‐Al and low Ti content Pd‐Ti alloys, the enthalpy becomes less exothermic with increasing lattice contraction. The dilute phase solubility at the same temperature as reflected by the relative chemical potential of dissolved hydrogen at infinite dilution, Δμ 0 H , increases with increasing lattice expansion for the expanded alloys, with the exceptions of Pd‐Pt and Pd‐Nb (Ta), whereas for the contracted alloys, the solubility decreases with increasing lattice contraction, with the exception of the Pd‐Li alloys. The standard free energy change, Δ G 0 plat' for B‐hydride formation in the expanded alloys decreases with increase of lattice expansion with the exceptions of the Pd‐Pt, Pd‐Zr, Pd‐Sb, Pd‐Nb(Ta) and Pd‐Mn alloys. For the contracted alloys, the B‐hydride becomes less stable with increasing lattice contraction except for the Pd‐Li alloys. The isobaric hydrogen solubilities in Pd alloys at relatively high pressures may be attributed to the influence of the solute metal atoms on the Pd band structure and to the exclusion of H from site occupation due to solute atoms in the nearest neighbor shells; both of these effects are independent of the lattice expansion and contraction.
pH Changes That Induce an Axial Ligand Effect on Nonheme Iron(IV) Oxo Complexes with an Appended Aminopropyl Functionality (2021)

Nonheme iron enzymes often utilize a high-valent iron(IV) oxo species for the biosynthesis of natural products, but their high reactivity often precludes structural and functional studies of these complexes. In this work, a combined experimental and computational study is presented on a biomimetic nonheme iron(IV) oxo complex bearing an aminopyridine macrocyclic ligand and its reactivity toward olefin epoxidation upon changes in the identity and coordination ability of the axial ligand. Herein, we show a dramatic effect of the pH on the oxygen-atom-transfer (OAT) reaction with substrates. In particular, these changes have occurred because of protonation of the axial-bound pendant amine group, where its coordination to iron is replaced by a solvent molecule or anionic ligand. This axial ligand effect influences the catalysis, and we observe enhanced cyclooctene epoxidation yields and turnover numbers in the presence of the unbound protonated pendant amine group. Density functional theory studies were performed to support the experiments and highlight that replacement of the pendant amine with a neutral or anionic ligand dramatically lowers the rate-determining barriers of cyclooctene epoxidation. The computational work further establishes that the change in OAT is due to electrostatic interactions of the pendant amine cation that favorably affect the barrier heights.
Energy efficient and scalable device-to-device discovery protocol with fast discovery (2013)

Device-to-device (D2D) discovery is an important step toward numerous applications of device-to-device communications. However, the design of D2D discovery protocols also faces the challenges of distributed nature, energy efficiency, scalability, and fast discovery. In this paper, we propose a D2D discovery protocol called synced distributed protocol that can efficiently resolve these challenges. The key idea behind our protocol is to group devices in a neighborhood such that devices in a group will take turns to announce the existence of other devices in a group. Hence, a device can reduce the period of announcing its existence and have the advantages of energy efficiency and scalability. Further, the transmissions from other devices in the group still guarantee fast discovery. We validate our protocol design by analysis and simulations. Specifically, we prove that our proposed protocol will function correctly in a static environment with minor assumptions and simulate our protocol in the OPNET 802.11n model. Simulation results confirm that our algorithm is scalable and can achieve low duty cycle and fast discovery. For mobile environment, we propose enhanced techniques and use simulation to show that the enhanced techniques has the benefits of increasing the group size.

Principes d'invariance pour les champs aléatoires stationnaires (1998)

Dans cette these, nous etablissons des resultats asymptotiques de type theoreme limite central pour les sommes partielles issues d'un champ aleatoire stationnaire x. A toute suite de sous-ensembles finis d'un reseau dont le cardinal tend vers l'infini, on associe la suite sn des sommes partielles normalisees issues du champ aleatoire x. Le critere p que l'on considere est de nature projective : pour des variables x(i) centrees et de carre integrable, on suppose qu'une serie d'esperances conditionnelles converge normalement dans l'espace des variables aleatoires integrables. Dans le chapitre 1, nous montrons que si p a lieu, alors la suite sn converge vers un melange de gaussiennes. Plus precisement, la limite est le produit d'une gaussienne centree reduite et d'un terme de variance mesurable par rapport a la tribu des elements invariants. Dans le cas de la dimension 1, on peut ameliorer le critere p en supposant seulement la convergence simple de la serie d'esperances conditionnelles. Grace a une inegalite maximale de type kolmogorov-doob, nous obtenons sous ce nouveau critere la convergence de la ligne de donsker normalisee sn(t) vers un melange de browniens. Cette condition est plus fine que la condition projective de gordin (1969) et fournit de nouveaux resultats pour les chaines de markov stationnaires. Dans les chapitres 3 et 4, nous etablissons des inegalites exponentielles de type hoeffding (sous une condition projective) et bernstein (sous une condition melangeante) pour les sommes partielles issues de champs aleatoires stationnaires. Grace a des methodes de chainage classiques, nous obtenons alors des principes d'invariance pour des processus de sommes partielles indexes par les ensembles d'une classe a. La seule restriction sur la taille de a en terme d'entropie provient de la condition d'existence du mouvement brownien indexe par les ensembles de a.
Serum Neurofilament light correlates with CADASIL disease severity and survival (2018)

Serum NfL levels correlate with disease severity, disease progression and 17-year survival in CADASIL patients. Serum NfL is a promising biomarker to monitor and predict disease course in CADASIL, as well as potentially assessing therapeutic response in future clinical trials.
The Development of Monoclonal Antibodies for the Therapy of Cancer (1998)

Monoclonal antibodies (Mabs) were first described by Köhler and Milstein in 1975. Not only did this discovery lead to a Nobel prize, but it created an enormous scientific field that has now become a multimillion dollar industry. Mabs made the transition from laboratory reagents to clinical diagnostics very quickly. However, their development as therapeutic agents was, as predicted, more costly and time-consuming. Indeed, clinicians and scientists were required to learn a new set of rules for using these large, immunogenic, targeted agents in humans. Nevertheless, in 1997 the first Mab was licensed in the U.S. and several others will soon follow. In this review, we discuss Mab-based strategies for the treatment of cancer. We compare native, fragmented, recombinant and chimeric antibodies, bispecific antibodies, immunoconjugates, and immunoliposomes. The rationale for their development, their advantages, their in vitro and in vivo performance, and their clinical usefulness are discussed.
Facteurs membranaires controlant l'entree du virus de l'immunodeficience humaine dans les cellules cibles (1994)

L'infection d'une cellule cible par le virus de l'immunodeficience humaine (hiv) necessite une etape de fusion membranaire, provoquee par l'interaction entre le recepteur cd4, et une des glycoproteines d'enveloppe virale, la gp120. Cette meme interaction est capable de provoquer la fusion entre deux cellules lorsque l'une exprime cd4 et l'autre exprime les glycoproteines virales, gp120 et gp41. L'enveloppe de hiv partage un grand nombre de caracteristiques moleculaires et fonctionnelles avec d'autres enveloppes virales. La fusion qu'elle provoque manifeste des analogies avec les phenomenes de fusion membranaire que l'on retrouve dans certaines fonctions cellulaires. Pour cette raison, ici sont d'abord traites les principes generaux de la fusion membranaire et de la fusion induite par les virus, pour definir le contexte dans lequel se place l'exemple de la fusion induite par l'enveloppe de hiv et les facteurs cellulaires dont elle depend. Le travail decrit demontre l'existence de facteurs humains, necessaires a l'aboutissement de la fusion induite par l'interaction entre cd4 et la gp120. Il montre leur localisation cellulaire et donne des indications sur leur nature biochimique
de Haas-Shubnikov Effect in Antimony (1963)

The oscillatory components of the transverse magnetoresistance of single crystals of antimony has been measured at 1.15\ifmmode^\circ\else\textdegree\fi{}K in the range of magnetic fields from 4000-25 000 G using a derivative technique. Measurements were made for the field in the $x\ensuremath{-}z$, $y\ensuremath{-}z$, and $x\ensuremath{-}y$ planes. Two sets of ellipsoidal carriers are clearly observed. One of the carriers was that observed by Shoenberg for which we found: ${\ensuremath{\alpha}}_{11}{\ensuremath{\alpha}}_{22}=0.334\ifmmode\times\else\texttimes\fi{}{10}^{28}{{E}_{F}}^{2}$, ${\ensuremath{\alpha}}_{11}{\ensuremath{\alpha}}_{33}=0.563\ifmmode\times\else\texttimes\fi{}{10}^{28}{{E}_{F}}^{2}$, and ${\ensuremath{\alpha}}_{11}{\ensuremath{\alpha}}_{23}=0.352\ifmmode\times\else\texttimes\fi{}{10}^{28}{{E}_{F}}^{2}$. We also found for the second set of carriers ${\ensuremath{\beta}}_{11}{\ensuremath{\beta}}_{22}=0.0227\ifmmode\times\else\texttimes\fi{}{10}^{28}{{E}_{F}}^{2}$, ${\ensuremath{\beta}}_{11}{\ensuremath{\beta}}_{33}=0.625\ifmmode\times\else\texttimes\fi{}{10}^{28}{{E}_{F}}^{2}$, ${\ensuremath{\beta}}_{11}{\ensuremath{\beta}}_{23}=0.0424\ifmmode\times\else\texttimes\fi{}{10}^{28}{{E}_{F}}^{2}$, and ${\ensuremath{\beta}}_{22}{\ensuremath{\beta}}_{33}\ensuremath{-}{{\ensuremath{\beta}}_{23}}^{2}=0.0627\ifmmode\times\else\texttimes\fi{}{10}^{28}{{E}_{F}}^{2}$. Discussions are included relating this data to that of other experiments.
Numerical Investigation of the Performance of OAM-Mode Shifting Recirculating Delay Loop Under the Effect of Mode Shifter Displacement (2022)

We investigate the effect of OAM mode shifter displacement on the performance of the OAM-mode shifting recirculating delay loop by simulating the beam propagation using Kirchhoff-Fresnel diffraction. Simulation results indicate that 20 delayed replicas may be obtained with >10dB signal-to-crosstalk ratio (SCR) if alignment is perfect and $\ell_{\mathrm{shift}}$=+1.
Improved understanding of head-related transfer functions through sagittal-plane spectral decomposition (2016)

Head-related transfer functions (HRTFs) capture the listener-specific modifications that are imparted on a sound as it travels from a specific location in space, interacts with the listener’s head, shoulders, and outer ears, and arrives at the ear drums. HRTFs have often been decomposed into a combination of two parts to aid modeling and analysis: a diffuse-field transfer function (DFTF) that captures non-directional but still listener-specific spectral details of the HRTF, and a directional transfer function (DTF) that captures all of the listener-specific directional information. Because the DTF contains spectral variation along all spatial dimensions, it does not provide a way to separate the spectral cues responsible for lateral and sagittal plane localization judgments, which are largely independent. As an alternative approach, decomposing an HRTF along each sagittal plane (aka along the “cones-of-confusion”) provides similar benefits to DTF analysis while providing additional insights into the spectral cues responsible for lateral and vertical localization, independently. This talk will provide a detailed overview of sagittal-plane spectral decomposition along with experimental results showing how the technique can be applied to improve localization with non-individualized HRTFs, separate general and idiosyncratic HRTF features, and cluster listeners’ HRTFs based on spectral similarity.
Autosomal dominant cerebellar ataxia type I. MRI-based volumetry of posterior fossa structures and basal ganglia in spinocerebellar ataxia types 1, 2 and 3 (1998)

Twenty-six patients suffering from autosomal dominant cerebellar ataxia type I were subjected to a genotype-phenotype correlation analysis using molecular genetic assignment to the genetic loci for spinocerebellar ataxia type 1, 2 or 3 (SCA1, SCA2, SCA3) and MRI-based volumetry of posterior fossa structures and basal ganglia nuclei. There was significant atrophy of the cerebellum and brainstem in all three SCA mutations compared with a group of 31 age- and sex-matched controls. Comparison between the SCA groups showed that cerebellar and brainstem atrophy was more severe in SCA2 than in SCA1 and SCA3. Putaminal and caudate volume was reduced only in SCA3, but not in SCA1 and SCA2. A set of three morphological criteria was defined that enabled us to assign all SCA2 and SCA3 patients correctly to the underlying genotype. In contrast, these criteria did not distinguish SCA1 from SCA2 and SCA3. Regression analysis failed to reveal a significant association between CAG repeat length and the volumes of the respective brain structures in any of the SCA mutant types. The present data provide in vivo evidence that SCA2 and SCA3 lead to distinct patterns of brain atrophy, while the atrophy changes in SCA1 overlap with both SCA2 and SCA3.
Immunologic evaluation of human bladder cancer: In vitro studies (1975)

Human bladder cancer tissue were obtained from 31 patients with the histologic diagnosis of transitional cell cancer. Attempts to grow these tumors in tissue culture resulted in 18 primary cultures but only 2 long-term cell lines. Cell-mediated and serum cytotoxicity was demonstrated in both autochthonous and allogeneic experiments. This would suggest a cross-reacting common antigen. In the patients showing positive cytotoxicity, no recurrence of tumor could be demonstrated with up to 3 years' followup after therapy.
DMP: Deterministic Shared-Memory Multiprocessing (2010)

Shared-memory multicore and multiprocessor systems are nondeterministic, which frustrates debugging and complicates testing of multithreaded code, impeding parallel programming's widespread adoption. The authors propose fully deterministic shared-memory multiprocessing that not only enhances debugging by offering repeatability by default, but also improves the quality of testing and the deployment of production code. They show that determinism can be provided with little performance cost on future hardware.
Long-term treatment of menorrhagia with mefenamic acid. (1983)

Thirty-six women with menorrhagia were treated with mefenamic acid during all menstrual periods for more than 1 year. These women had experienced objective and subjective benefit--menstrual blood loss was reduced and other menstrual symptoms improved during a preliminary 4-cycle double-blind placebo-controlled trial with mefenamic acid (placebo cycles: 65.6 +/- 5.3 ml; mefenamic acid cycles: 45.3 +/- 5.1 ml, mean +/- SEM). This reduction in menstrual blood loss was maintained at 6 to 9 months (49.2 +/- 9.9 ml) and at 12 to 15 months (42.8 +/- 4.8 ml) after the trial. These reductions were significant at the 6- to 9-month (paired t test = 2.18; P less than .05) and the 12- to 15-month interval (paired t test =- 4.40; P less than .001). Significant sustained reductions in blood loss were seen in the women with menorrhagia due to ovulatory dysfunctional bleeding and in those who had undergone tubal sterilization. Significant reductions were also seen in dysmenorrhea, headache, nausea, diarrhea, depression, number of sanitary towels used, and number of mefenamic acid capsules taken. A significant increase in serum ferritin was found between admission and completion of the follow-up trial in 11 women (P less than .01).

Decoy NF‐κB fortified immature dendritic cells maintain laryngeal allograft integrity and provide enhancement of regulatory T cells (2009)

iDC immunosuppression maintains laryngeal allograft integrity up to 60 days post-transplantation. Regulatory T cells are enhanced at the allograft site, which serves to suppress immune cell activation and induce self-antigen tolerance. iDC injection may lessen post-transplant comorbidities by decreasing the systemic immune response and favorably affecting concurrent immunosuppressive dose sequencing for laryngeal allograft preservation.
COMPOSITION OF CEMENT LINES IN BONE (1965)

In cement lines and in adjacent Haversian systems from bone of orangutan and whale the content of mineral, organic matrix, and sulfur was determined microradiographically and the arrangement of the mineral part was studied by X-ray diffraction. Cement lines were often highly mineralized, maximum being 50% by volume. This value was a few per cent higher than the highest value for Haversian systems. Content of collagen varied to a certain extent, and low values were found in cement lines. Determinations of sulfur and X-ray diffraction studies of the organization of the mineral fraction did not reveal any significant differences between cement lines and adjacent osteons.
Simultaneous uptake and utilisation of glucose and xylose byClostridium thermohydrosulfuricum (1993)

Growth studies of Clostridium thermohydrosulfuricum Rt8.B1 demonstrated that glucose and xylose were used simultaneously when supplied together at nonlimiting concentrations in pH-controlled batch culture. Under conditions of hyperbolic growth, both catabolite repression and inducer exclusion were absent. Glucose did not repress xylose metabolism (i.e. xylose permease and xylose isomerase genes were expressed in the presence of glucose and were not subject to catabolite inhibition when glucose was added to cultures growing on high concentrations of xylose). The kinetics of glucose and xylose utilisation indicated that separate systems were present for the uptake of these substrates when supplied together. Glucose utilisation was biphasic, indicating high- and low-affinity systems for glucose uptake. Xylose utilisation was directly proportional to the xylose concentration, suggesting a facilitated diffusion mechanism was operative for uptake.
A time-domain pitch extraction scheme for noisy speech signals (2007)

A new pitch detection algorithm for speech corrupted by a white or a car noise is presented, considering the LP residual of the pre-processed speech as a representation for the GC events. A weighted and harmonically summed AMSF of the LP residual is proposed that is able to effectively quell the pitch-errors in the presence of a noise. The peaks of AMSF at different pitch-harmonic locations are added and weighted by a periodicity dependent weighting factor for every possible pitch period. The resulting weighted and harmonically summed AMSF of the LP residual is globally maximized to extract the desired pitch period. The proposed method is able to reflect its efficacy to a significant extent for extracting pitch of both low and high-pitched speakers in the white or car environmental noise. Simulation results have shown that the proposed method outperforms the pitch detection algorithms implemented in the same noisy environment.
Urethane Coatings (1985)

Urethane coatings were first developed by Otto Bayer and his coworkers in the laboratories of the I. G. Farbenindustry, today's Farbenfabriken Bayer, in Leverkusen, West Germany. Although urethanes are characterized by the linkage -NH-C(=0)-0-, they may contain other functional groups such as ester, ether, urea, amide, and other groups. There are a number of syntheses leading to the formation of urethane polymers. However, the most important commercial route is the isocyanate addition polymerization, the reaction between di- and polyfunctional hydroxyl compounds such as hydroxy-terminated polyethers or polyesters and di- or polyisocyanates. When difunctional reactants are being used, linear polyurethanes are produced and the reaction can be schematically represented as follows: If the functionality of the hydroxyl or isocyanate component is increased to three or more, branched or cross-linked polymers are formed. The earliest commercial urethane coatings were based on polyester-polyisocyanate systems that exhibited excellent abrasion resistance, toughness, and a wide
