Field quantization and spontaneous emission in lossless dielectric multilayer structures (1997)

A complete set of cavity modes in planar dielectric multilayer structures is presented which naturally includes the guided modes. We show that most of these orthonormal fields can be derived from a coherent superposition of plane waves incident on the stack from the air and from the substrate. Using this set of cavity modes, we present a quantization scheme in idealized lossless stratified dielectric structures. This enables us to discuss the vacuum quantum fluctuations of the fields within the multilayer stack. The spontaneous emission of photons by a two-level atom located at any position inside the stratified planar structure is derived using the quantum approach and standard perturbation theory. The spontaneous emission rate as well as the radiation pattern in the air, in the substrate and in the guided mode are presented. Finally, a numerical analysis of the radiative properties of an erbium atom located in an asymmetrical Fabry - Perot multilayer structure is investigated. We show that a large part of the emitted power is directed in one half-space although a significant amount of light remains trapped in the guided modes of the structure.
Spring‐viscous damper systems for combined seismic and vibration isolation (1992)

Abstract The coupled lateral‐vertical‐rocking dynamic response of spring‐viscous damper isolated structures is considered. The force‐displacement relation of the viscous dampers is described by an experimentally calibrated fractional derivative viscoelasticity model. The equations of motion are derived and reduced to a form for direct solution by the discrete Fourier transform method. The validity and accuracy of the derived solution are demonstrated by comparison with shake table test results. The developed analysis procedure is employed in the seismic analysis of a recently constructed isolated structure. The analytical and experimental results demonstrate that spring‐viscous damper isolation systems are capable of providing both effective seismic and vibration isolation.
Study of the Adducts of Aliphatic and Aromatic Sulphoxides with Boron Trifluoride. Compounds of These Adducts with Copper (II) (1993)

Abstract The adducts of boron trifluoride and aromatic and aliphatic sulphoxides were prepared. The formulae proposed are as follows: R2SO-BF3, where R = Bun. (1); R = Bz. (2); R = Ph, (3) The adduct corresponding to the dimethylsuiphoxide, Me2SO BF3 (4) was also obtained according to the method reported in the literature. The adducts were treated with CuCl2 2H2O to obtain the copper compounds, of formula [CuCl2 (R2SO BF3) (H2O)2], where R = Me, (5); R = Bun, (6); R = Bz, (7); R = Ph, (8). All the compounds were characterized by elemental analysis, thermal analysis and I.R. spectroscopy. The BF3 adducts were studied by 1H and 13C-NMR spectroscopy. The copper compounds were studied by electronic spectroscopy and magnetic susceptibility.
Expansion of adipose tissue mesenchymal stromal progenitors in serum‐free medium supplemented with virally inactivated allogeneic human platelet lysate (2010)

S/D-PL is an alternative to FBS for AT-MSC maintenance and expansion, does not compromise the differentiation capacity nor the immunophenotype, and may accelerate chondrogenesis. S/D-PL protocols for MSC clinical scale-up may represent a major step toward challenging new use in stem cell therapies.
Unrelated Donor Cord Blood Transplantation for Children with Severe Sickle Cell Disease: Results of a Phase II Study from the Blood and Marrow Transplant Clinical Trials Network (2012)

Most children with sickle cell disease (SCD) who might otherwise be considered for curative hematopoietic cell transplantation (HCT) lack a healthy matched related donor. Barriers to alternative donor HCT for SCD include graft rejection, graft-versus-host disease(GVHD) and regimen-related toxicities. To address these problems, we initiated a phase II trial of unrelated bone marrow or cord blood transplantation (CBT) using a novel, alemtuzumab-based, reduced intensity conditioning (RIC) regimen in children with severe SCD. Here we report the results for the 8 children who received unrelated CBT on this study. Patients were prepared for HCT following alemtuzumab(10, 15 and 20 mg on day -21, -20 and -19 respectively), fludarabine(30 mg/m2 day -8 to -4) and melphalan(140 mg/m2 day -3). Cyclosporine or tacrolimus and mycophenolate were administered for GVHD prophylaxis. Donor/recipient HLA match status was 5/6 in all patients based on low/intermediate resolution molecular typing at HLA -A, -B, and high resolution typing at -DRB1. Median recipient age was 13.7 years (range 7.4 to 16.2 years). The median pre-cryopreservation total nucleated cell dose was 6.4x107/kg (range 3.1 to 7.6) and the median post-thaw infused CD34 cell dose was 1.5x105/kg (range 0.2 to 2.3). The conditioning regimen demonstrated a favorable safety profile. All patients achieved an absolute neutrophil count>500/mm3 by day 33 (median 22 days). Six of eight patients had a platelet recovery to > 50,000/mm3 by day 100. Five patients had autologous hematopoietic recovery and three patients had sustained full donor engraftment. Two of 3 engrafted patients developed grade II acute GVHD. Of these, one developed extensive chronic GVHD that was fatal 14 months post-transplant. With a median follow up of 1.8 years (range 1 – 2.6), 7 patients are alive with a 1-year survival of 100% and 2 are alive without graft failure or disease recurrence. Total nucleated or CD 34+ cell dose, HLA mismatch or ABO mismatch were not correlated with graft rejection in this small series. This RIC regimen was associated with a high rate of graft rejection after unrelated CBT. The CBT arm has been closed, but the trial remains open to enrollment for eligible patients with 8/8 HLA allele matched unrelated bone marrow donors. Novel approaches aimed at reducing graft rejection while minimizing toxicity will be needed before RIC unrelated donor CBT can be widely adopted for transplanting children with severe SCD.

Hybrid tracking approach using optical flow and pose estimation (2008)

This paper proposes an hybrid approach to estimate the 3D pose of an object. The integration of texture information based on image intensities in a more classical non-linear edge-based pose estimation computation has proven to highly increase the reliability of the tracker. We propose in this work to exploit the data provided by an optical flow algorithm for a similar purpose. The advantage of using the optical flow is that it does not require any a priori knowledge on the object appearance. The registration of 2D and 3D cues for monocular tracking is performed by a non linear minimization. Results obtained show that using optical flow enables to perform robust 3D hybrid tracking even without any texture model.
Transfer of a CFA/I-ST plasmid promoted by a conjugative plasmid in a strain of Escherichia coli of serotype O128ac:H12 (1980)

Escherichia coli strains belonging to serotype O128ac:H12 and producing heat-stable enterotoxin (ST) and colonization factor CFA/I were found in Sao Paulo in children with diarrhea, but not in normal children. Segregants occurred in such strains with a frequency of about 10%, which have lost the ability to produce ST and CFA/I at the same time. From one strain, both properties were transformed jointly in matings to an E. coli K-12 strain. All such ST+ CFA/I+ progeny had received two plasmids of length 97 and 64 kilobases in the matings. Insertion of a transposon, Tn5, carrying a gene for kanamycin resistance, into the two plasmids enabled us to select for kanamycin-resistant progeny in further matings. Analysis of such progeny strains in terms of plasmid content and production of ST and CFA/I revealed that the larger plasmid carries the genes for St and CFA/I and is not self-transmissible, whereas the smaller plasmid does not carry any recognizable phenotypic traits, but is conjugative and promotes cotransfer of the larger plasmid with a frequency of about 30%.

Solubilization of organic sludge by thermophilic aerobic bacteria as a pretreatment for anaerobic digestion (2000)

Solubilization of organic sludge by thermophilic aerobic bacteria as a pretreatment for anaerobic digestion was investigated. The thermophilic bacteria which solubilized organic sludge were isolated from the thermophilic aerobic digestion reactor. The bacterium type SPT2-1 could grow at pH ranging from 5.0 to 8.5 with optimal temperature at 60-70 degrees C. In batch experiments, 25-30% of volatile suspended solids (VSS) in the pre-heated sludge were solubilized on inoculating with the isolated bacteria although little was solubilized without inoculation. The isolated bacteria appeared to secret the extracellular enzymes including proteases and amylases. In continuous flow experiments, sludge solubilization rate (VSS removal) was around 40% under aerobic as well as microaerobic conditions. No accumulation of volatile fatty acids in the treated sludge was observed under aerobic conditions while significant amounts of them were accumulated under microaerobic conditions. Production of biogas on anaerobic digestion of the microaerobically-pretreated sludge was increased by 1.5 when compared with the sludge without pretreatment.
A proposal for classification of lymphoid neoplasms (by the International Lymphoma Study Group) (1994)

A new classification of lymphoid neoplasms, mostly based on existing terminology, is proposed by the International Lymphoma Study Group. The proposed classification was reached through a consensus of the members, despite their diverse backgrounds, and consists of a listing of currently recognized clinicopathological entities. These tumours are divided into three major categories: B-cell neoplasms, T-cell and postulated natural killer cell neoplasms, and Hodgkin's disease. The characterization of each entity is based on a synthesis of all available information. This concept departs from a purely morphological approach to lymphoma classification, which is considered to be inadequate, because many biologically distinctive lymphoma types can exhibit a broad and overlapping morphological spectrum. Some entities are provisional, pending further data to confirm that their recognition is reproducible. The salient clinicopathological features of each entity are summarized in this review.
Preface to the second edition (2002)

This second edition of Typology and universals is almost completely rewritten from the first edition. Although the number of chapters and much of their content remains the same, many major changes have been made, largely due to the maturing of typology as an approach to language. The most important innovation is the systematic employment of the semantic map model, now widely used in typological research. Also, I have reorganized the material so that typological generalizations and their explanations are now more closely integrated.
Miniature loop heat pipes-a promising means for cooling electronics (2005)

Loop heat pipes (LHPs) are highly efficient heat-transfer devices, which have considerable advantages over conventional heat pipes. Currently, miniature LHPs (MLHPs) with masses ranging from 10-20 g and ammonia and water as working fluids have been developed and tested. The MLHPs are capable of transferring heat loads of 100-200 W for distances up to 300 mm in the temperature range 50-100/spl deg/C at any orientation in 1-g conditions. The thermal resistance for these conditions are in the range from 0.1 to 0.2 K/W. The devices possess mechanical flexibility and are adaptable to different conditions of location and operation. Such characteristics of MLHPs open numerous prospects for use in cooling systems of electronics and computer systems.
Lift jet installational experience (1965)

A review of some of the progress made in lift jet installations is presented in this paper. At the heart of it all is the low cost lightweight RB162 second generation lift jet which is simple and makes extensive use of glass reinforced plastics. Examples of plastic components are shown. The higher thrust/weight and thrust/volume ratio of a third generation lift jet are revealed. The weight of installed features is of comparable importance to the weight of the basic engine. Installed weight has been reduced over three lift jet generations, more than keeping pace with the improvements in basic engine thrust/weight ratio. Weight breakdowns are given for the V.T.O.L. equipment in a fighter‐type aircraft representative of all three generations. Progress on lift intake and exhaust jet deflectors is shown with reference to specific examples. Ground erosion is briefly discussed and shown to be greatly reduced by multiple nozzles and the rolling take‐off technique. Progress being made on some of the problems associated with installing eight lift jets in a V.T.O.L. strike aircraft is briefly discussed with reference to maintenance and instrumentation.
Enhanced electrical conductivity of zinc oxide thin films by ion implantation of gallium, aluminum, and boron atoms (1994)

Effect of ion implantation on the conductivity of zinc oxide was examined by using highly resistive zinc oxide thin films deposited by rf magnetron sputtering at room temperature to reduce the effect of oxygen vacancies. With the doping by 1×1017 atoms/cm2 gallium the conductivity is 1.0×103/Ω cm for as-implanted film and it increases up to 3.7×103/Ω cm, the highest conductivity reported for zinc oxide films, with raising the annealing temperature in either a nitrogen or oxygen atmosphere. The conductivity of aluminum-doped films is slightly lower than those of gallium-doped films. Among the elements gallium, aluminum, and boron, gallium is the most effective in enhancing the conductivity and boron is the least. The order of the effectiveness is explained by the electronegativity of the dopants.
T-cell migration to vascularized organ allografts (2013)

Antigen-driven migration of effector and memory T cells sheds new light on the pathogenesis of transplant rejection and predicts that interrupting the TCR-triggered 'inside-out' signaling pathway, rather than that initiated by Gαi-coupled chemokine receptors, is a key approach to preventing rejection.
SIP-enpowered OBS network architecture for future IT services and applications (2007)

This paper presents a novel application-aware network architecture for evolving and emerging IT services and applications. It proposes and analyses network architectures that integrate Session Initiation Protocol (SIP) with Optical Burst Switched (OBS) protocols on a unified manner. We suggest various SIP-OBS layering architectures for possible deployment as well as a number of end-to-end resource discovery protocols (both for network and non-network resources). Finally the paper reports of a SIP-enpowered OBS Testbed where this approach was experimentally validated.
The evolution of “Life”: A Metadarwinian integrative approach (2017)

It is undeniably very logical to first formulate an unambiguous definition of "Life" before engaging in defining the parameters instrumental to Life's evolution. Because nearly everybody assumes, erroneously in my opinion, that catching Life's essence in a single sentence is impossible, this way of thinking remained largely unexplored in evolutionary theory. Upon analyzing what exactly happens at the transition from "still alive" to "just dead," the following definition emerged. What we call "Life" (L) is an <i>activity</i>. It is nothing other than the total sum (∑) of all communication acts (C) executed, at moment t, by entities organized as sender-receiver compartments: L = ∑C Such "living" entities are self-electrifying and talking ( = communicating) aggregates of fossil stardust operating in an environment heavily polluted by toxic calcium. Communication is a multifaceted, complex process that is seldom well explained in introductory textbooks of biology. Communication is instrumental to adaptation because, at the cellular level, any act of communication is in fact a problem-solving act. It can be logically deduced that not Natural Selection itself but communication/problem-solving activity <i>preceding selection</i> is the universal driving force of evolution. This is against what textbooks usually claim, although doubt on the status of Natural Selection as driving force has been around for long. Finally, adopting the sender-receiver with its <i>2</i> memory systems (genetic and cognitive, both with their own rules) and 2 types of progeny ("physical children" and "pupils") as the universal unit of architecture and function of all living entities, also enables the seamless integration of cultural and organic evolution, another long-standing tough problem in evolutionary theory. Paraphrasing Theodosius Dobzhansky, the very essence of biology is: "Nothing in biology and evolutionary theory makes sense except in the light of the ability of living matter to communicate, and by doing so, to solve problems."
Diagnostic Criteria of $^{99m}Tc$-diethylenetriaminepentaacetic acid Captopril Renal Scan for the Diagnosis of Renovascular Hypertension by Unilateral Renal Artery Stenosis (2004)

Purpose: We compared captopril renal scintigraphic criteria for the diagnosis of renovascular hypertension by unilateral renal artery stenosis. Materials and Methods: The study group consisted of 24 patients (m/f : 16/8, age: years) with unilateral renal artery stenosis who underwent renal artery revascularization and captopril renal scintigraphy with -diethylenetriaminepentaacetic acid between May 1995 and April 2004. The blood pressure response was classified as cure/improvement or failure. We evaluated captopril-induced changes in relative function (BCfun) and renogram grade (0 to 5: 0=normal, and 5=renal failure pattern without measurable uptake) (CBren) and the difference of renograms between the normal and stenotic kidney on captopril scan (CNren). Results: light of 24 patients were cured and 11 improved and 5 patients were classified as failed revascularization. Significant predictors of a cure or improvement of blood pressure were younger age, stenosis by fibromuscular dysplasia or arteritis, BCfun, CBren and CNren. Areas under the receiver operating characteristic curve of age, BCfun, CBren and CNren were not significantly different. Positive and negative predictive values of predictors were 100% and 42% (age ): 92% and 50% (BCfun ): 92% and 75% (CBren ), and 90% and 60% (CNren ), respectively. Conclusion: Captopril induced changes in renal function and renogram can reliably predict hypertension response to revascularization. Renogram pattern on captopril scan can diagnose renovascular hypertension without baseline data in patients with unilateral renal artery stenosis.
Application of NMR Techniques to Organometallic Compounds. (1993)

Application of NMR techniques, especially a spin saturation transfer technique, to several organometallic compounds are reported with emphasis on compounds undergoing fluxional behavior with two-electron-threecentered bonds such as a M-H-C bond, i.e. agostic interaction, and a M-H-H bond, i.e. a molecular hydrogen ligand. 13C spin saturation transfer experiments on the tautomers of H2Os3(CO)10(μ-CH2) and HOs(CO)10(μ-CH3) show intramolecular hydrogen exchange to convert all of the four isomers. 1H spin saturation tranfer experiments on [RuH(diop)2] PF6 show intramolecular hydrogen exchange between the hydride ligand and an aliphatic proton, presumably involving an agostic interaction, of the phosphine ligand. 1H spin saturation transfer experiments on [RuH(η2-H2)(dppp)2]PF6 show intramolecular hydrogen exchange between the molecular hydrogen and the hydride ligand. Application of isotopic perturbation of resonance to agostic interaction is mentioned as a method to show the presence of a proton of an agostic interaction undergoing a rapid exchange.
Rotational Entropy Driven Separation of Alkane/Isoalkane Mixtures in Zeolite Cages (2004)

Ausgebremst: Abhängig vom Trägheitsradius bleibt Molekülen die Fähigkeit zur Rotation in Zeolithkäfigen erhalten oder sie verlieren sie (siehe Bild). Diese Unterschiede in der rotationsbedingten Adsorptionsentropie führen dazu, dass verzweigte Alkane in Zeolithen wie MCM-22 besser aufgenommen werden als ihre linearen Strukturisomere, was die Trennung der beiden Molekültypen ermöglicht.
H/sub /spl infin// design for systems with input saturation: an LMI approach (1997)

A design technique is proposed to improve disturbance attenuation for systems with input saturation. The main results of the paper rely on a multiobjective approach which combines the quadratic stabilization design technique with constraint on the input saturation, which is taken into account using the star-norm approach. For the full state feedback problem, the sufficient conditions for feasibility are expressed in terms of linear matrix inequalities (LMIs). For the output feedback design, we assume the controller to have an observer-based structure. The sufficient conditions for the output feedback controller to recover the full state problem are also given in terms of LMIs. The feasibility of the high performance output feedback controller is guaranteed if the system can satisfy certain conditions. The validity and applicability of the proposed method are illustrated by two examples.
