Multi packet reception and network coding (2010)

We consider throughput and delay gains resulting from network coding used to complement multi-packet reception in a fully connected network with broadcast traffic. The network is comprised of N nodes, J of which have data packets to be distributed to all other nodes. Owing to half-duplex constraints, a transmitting node is not able to receive data from other transmitting nodes in the same time slot. This requires a node to be back-filled with the information that it is missing. We consider singlepacket reception, (for which network coding alone yields no gain), multi-packet reception without network coding, and combined multi-packet reception and network coding. We show that the initial transmissions and the back-filling process can be greatly sped up through a combination of network coding and multi-packet reception. In particular, we show that MPR capability of 2 will not reduce the total delivery time for packets within a data network unless network coding is used. We also demonstrate that a combination of network coding and multi-packet reception can reduce this time by a factor of m, where m is the MPR capability of the system. We demonstrate that network coding can substitute for some degree of MPR and achieve the same, or almost the same, performance as the higher degree of MPR without network coding. In effect, network coding allows almost double the traffic for a given level of MPR.
Dinâmica de nutrientes em tecidos foliares de cana-de-açúcar após aplicação de herbicidas (2008)

Avaliaram-se, neste trabalho, os efeitos dos herbicidas ametryn, 2,4-D, trifloxysulfuron-sodium e da mistura ametryn+trifloxysulfuron-sodium na nutrição mineral e no crescimento da cana-de-açúcar. Para isso, utilizou-se o delineamento inteiramente casualizado no esquema de parcelas subdivididas, com quatro repetições. Os efeitos dos herbicidas foram avaliados nas parcelas, e o efeito do tempo, expresso em dias após aplicação dos herbicidas (DAA), considerando as diversas amostragens nas subparcelas. Os herbicidas foram aplicados em pós-emergência, quando as plantas de cana-de-açúcar se apresentavam com três a quatro folhas. As características avaliadas foram: a altura e massa seca da parte aérea, o número de folhas, o número de perfilhos e as concentrações de macro e micronutrientes nos tecidos foliares das plantas. As concentrações de N, P e Mg nos tecidos foliares não foram afetadas pelo uso dos herbicidas, independentemente da época de avaliação (15, 30, 45 e 60 DAA). Ao longo do tempo após a aplicação, constatou-se acréscimo da taxa de acúmulo (coeficiente beta0) dos nutrientes catiônicos Ca, Mg e K em plantas expostas ao ametryn+trifloxysulfuron-sodium. Quando da aplicação do 2,4-D, verificou-se redução na taxa de acúmulo de S e alteração na dinâmica dos nutrientes Mg, Ca e K, comparado à testemunha sem herbicida. Os herbicidas provocaram redução na concentração de Fe nessa cultura aos 15 DAA, na seguinte ordem: ametryn+trifloxysulfuron-sodium &gt; ametryn &gt; trifloxysulfuron-sodium &gt; 2,4-D. Em relação às plantas de cana-de-açúcar não tratadas com herbicida (testemunha), o herbicida trifloxysulfuron-sodium provocou acréscimo de 22,10% no acúmulo de massa seca da sua parte aérea aos 60 DAA. O número de perfilhos observados em plantas tratadas com trifloxysulfuron-sodium foi o dobro do encontrado com ametryn, demonstrando efeito negativo deste herbicida nessa característica. Evidenciaram-se neste trabalho os efeitos dos herbicidas na concentração dos nutrientes e o crescimento das plantas de cana-de-açúcar.
Distributed cloud monitoring using Docker as next generation container virtualization technology (2015)

Paradigm shift is happening these days that organizations are dismissive towards capital investment on owning infrastructural setup, rather going for cloud services offered by various cloud providers. Cloud providers are accountable to their service that should always be available, reliable and scalable. They speculate lot of time and money on human resources who test the entire cloud relentlessly and make sure it is in compliance with anticipated service-level agreement (SLA). This approach is unacceptable for long term consideration keeping in mind the growing industry need and unpredictable customer loads. Hence the next immediate necessity would be to automate the process. Usually these cloud services are web based and public APIs (North-Bound APIs) are exposed for executing certain actions on Cloud Portal (CP). There can be multiple CP instances across the globe to serve regional requests. This paper proposes an architecture using containers to automate testing of entire cloud environment through North-Bound APIs (NBAPI) of respective CP instances spread across the globe and use it as a foundation for distributed cloud monitoring. A dashboard is developed to manifest a current global health status of cloud with capability of Proactive alert to forestall any undesirable state.
Contributions of intrinsic mutation rate and selfish selection to levels of de novo HRAS mutations in the paternal germline (2013)

The RAS proto-oncogene Harvey rat sarcoma viral oncogene homolog (HRAS) encodes a small GTPase that transduces signals from cell surface receptors to intracellular effectors to control cellular behavior. Although somatic HRAS mutations have been described in many cancers, germline mutations cause Costello syndrome (CS), a congenital disorder associated with predisposition to malignancy. Based on the epidemiology of CS and the occurrence of HRAS mutations in spermatocytic seminoma, we proposed that activating HRAS mutations become enriched in sperm through a process akin to tumorigenesis, termed selfish spermatogonial selection. To test this hypothesis, we quantified the levels, in blood and sperm samples, of HRAS mutations at the p.G12 codon and compared the results to changes at the p.A11 codon, at which activating mutations do not occur. The data strongly support the role of selection in determining HRAS mutation levels in sperm, and hence the occurrence of CS, but we also found differences from the mutation pattern in tumorigenesis. First, the relative prevalence of mutations in sperm correlates weakly with their in vitro activating properties and occurrence in cancers. Second, specific tandem base substitutions (predominantly GC>TT/AA) occur in sperm but not in cancers; genomewide analysis showed that this same mutation is also overrepresented in constitutional pathogenic and polymorphic variants, suggesting a heightened vulnerability to these mutations in the germline. We developed a statistical model to show how both intrinsic mutation rate and selfish selection contribute to the mutational burden borne by the paternal germline.
Efficient production of mesencephalic dopamine neurons by Lmx1a expression in embryonic stem cells (2009)

Signaling factors involved in CNS development have been used to control the differentiation of embryonic stem cells (ESCs) into mesencephalic dopamine (mesDA) neurons, but tend to generate a limited yield of desired cell type. Here we show that forced expression of Lmx1a, a transcription factor functioning as a determinant of mesDA neurons during embryogenesis, effectively can promote the generation of mesDA neurons from mouse and human ESCs. Under permissive culture conditions, 75%-95% of mouse ESC-derived neurons express molecular and physiological properties characteristic of bona fide mesDA neurons. Similar to primary mesDA neurons, these cells integrate and innervate the striatum of 6-hydroxy dopamine lesioned neonatal rats. Thus, the enriched generation of functional mesDA neurons by forced expression of Lmx1a may be of future importance in cell replacement therapy of Parkinson disease.

Reactions of allene with triosmium and triruthenium clusters including coupling and oxidative addition: X-ray structure of the coupled allene compound [Os3(C6H8)(CO)10] (1987)

Allene (CH2CCH2) reacts with [Os3(CO)11(MeCN)] to give the known compound [Os3(µ-C3H4)(CO)11] and with [Os3(CO)10(MeCN)2] to give [Os3(µ3-C6H8)(CO)10], the single-crystal X-ray structure of which shows an open chain of metal atoms [Os–Os–Os 136.8(1)°] with the C6H8 ligand, formed by end-to-centre allene coupling, bridging three Os atoms through µ,η2-vinyl and η3-allyl linkages. U.v. photolysis of [Os3(µ-C3H4)(CO)11] gives mainly [Os3H(µ3-σ,η2,η2-CHCCH2)(CO)9] which isomerises thermally to [Os3H(µ3-σ,σ,η3-CHCHCH)(CO)9]. In contrast, thermolysis of [Os(µ-C3H4)(CO)11] gives mainly [Os2(µ-σ,η3-C3H4)(CO)7](92%; reaction under CO). Thus photolysis leads to Os–CO and C–H cleavages and thermolysis to Os–Os cleavages. Reaction of [Ru3(CO)11(MeCN)]with allene at 0 °C gives [Ru2(µ,σ,η3-C3H4)(CO)7] with no evidence for trinuclear products. Tetramethylallene reacts slowly with [Os3(CO)11(MeCN)]to give [Os3(C3Me4)(CO)10] of unknown structure.
Non‐quaternary suppression with flip‐back: A useful technique for high‐resolution NMR of solids (1985)

Abstract A modification to the well‐established non‐quaternary suppression pulse sequence used in high‐resolution solid‐state NMR is proposed which allows the inclusion of a ‘flip‐back’ pulse. The utility of such a sequence is demonstrated by spectra obtained using the standard and modified NQS sequences for a glycidyl ether derivative.
The Effect of Hypothermia and Hyperthermia on Photodynamic Therapy of Normal Brain (1995)

The effect of whole body hyperthermia and hypothermia in conjunction with photodynamic therapy (PDT) was determined on normal rat brain. Hyperthermia animals (Group I, n = 18) were warmed until their core body temperature reached 40 degrees C, (brain temperature, 39.7 +/- 0.5 degree C) and maintained at 40 +/- 1 degree C for 30 minutes prior to and after PDT. Hypothermia (Group II, n = 31) animals were cooled to 30 +/- 1 degree C (brain temperature, 29.3 +/- 0.4 degree C) for 1 hour. PDT treatment was performed, and the body temperature of the animals was maintained at 30 degrees C for 2 hours post-PDT. A population of animals was subjected to PDT under normothermic (Group III, n = 16; body temperature, 37 +/- 1 degree C; brain temperature, 36.7 +/- 0.8 degree C) conditions and treated in a manner identical to that of hyperthermic animals. PDT was performed with 17 J/cm2, 35 J/cm2, or 70 J/cm2 (100 mW/cm2). Photofrin (Quadralogic Technologies Ltd., Vancouver, Canada) (12.5 mg/kg) was injected intraperitoneally 48 hours prior to laser treatment on all three groups. Wet-dry weight measurements were obtained on a separate set of all three groups of animals (n = 27). Cortical lesion depths were measured, and pathological evaluation was made at 24 hours post-PDT. No difference in the wet-dry weight measurements or histopathology was present between the three groups of animals. Lesion depths for Group I animals did not significantly differ from Group III animals.(ABSTRACT TRUNCATED AT 250 WORDS)
Service design and human factors considerations in the introduction of personal communications services (2005)

Rapid advancements in telecommunications technologies are opening many new opportunities to broaden a service provider's customer base, and offer those customers more choices in order to personalize services. The advent of intelligent network technology design concepts allows rapid service introduction based on customer needs and the flexibility to personalize a service to an individual's needs through the Intelligent Network's Service Creation Environmentl. However, as Southwestern Bell's Personal Communications service design work has shown, the ability to offer robust, flexible, and personalized services is limited by the resulting complexity of the service and the customer's ability to easily understand how the service operates. We are faced with the following dilemma: How can we offer services with enough flexibility to meet a wide range of customers' needs while ensuring that any one customer is not inundated with too many features? This is an important issue since customers will not use - and therefore not pay for - services which they perceive to be too complex. This paper describes Southwestern Bell's first attempt to provide Personal Communications services using the robust capabilities of an intelligent network platforms. We examine how the service design process was conducted (using the axiom that services must be driven by your Marketing organization and not your technology organization), what we learned, and how we will improve our methodology in future endeavors. The implications of using a service prototyping platform are also discussed.
Synthesis, Optoelectronic Properties, Self-Association, and Base Pairing of Nucleobase-Functionalized Oligothiophenes (2018)

Device-relevant π-conjugated oligothiophenes with the canonical nucleobases directly embedded into the π-framework have been designed, synthesized, and characterized. These oligomers offer the ability to tune optoelectronic properties via the intimate merging of the nucleobase molecular electronic structure with base-pairing fidelity. Analysis of their optical and electronic properties in a hydrogen-bond-disrupting solvent (DMF) indicates that the nucleobase identity influences the intrinsic electronic properties of the semiconductors. These differences are supported by DFT calculations which demonstrate that the HOMO/LUMO orbitals are distributed differently for each compound. The solubility and competition between self-association and base pairing in a hydrogen-bond-supporting solvent (chloroform) was studied to better understand the oligomer behavior under conditions relevant for downstream solution processing into thin-film devices. These solution studies reveal that in each case base-pairing is preferred to self-aggregation; the relatively weak heteroassociation of 1A-1U (35 ± 5 M<sup>-1</sup>) should be amenable to facile solution processing and successive hydrogen bond formation in the solid state, while the strong heteroassociation between 1G and 1C (>10<sup>4</sup> M<sup>-1</sup>) should enable assemblies to be preformed in solution. These results are expected to enable the synthesis of more complex π-conjugated architectures and facilitate their extension to optoelectronic devices.

Subunits of the H+-ATPase of Escherichia coli. Overproduction of an eight-subunit F1F0-ATPase following induction of a lambda-transducing phage carrying the unc operon. (1980)

The proton-translocating ATPase complex (F1F0) of Escherichia coli was purified after inductin of a lambda-transducing phage (lambda asn5) carrying the ATPase genes of th unc operon. ATPase activity of membranes prepared from the induced lambda-unc lysogen was 6-fold greater than the activity of membranes prepared from strains lacking the unc-transducing phage, confirming the report of Kanazawa et al. (1979) Proc. Natl. Acad. Sci. U. S. A. 76, 1126-1130). The F1F0-ATPase complex was purified in comparable yield from either enriched membranes or control membranes using a modification of the procedure reported by Foster and Fillingame ((1979) J. Biol. Chem. 254, 8230-8236). EAch of the eight subunits that had been reported as components of the F1F0 complex from wild type E. coli was overproduced in the lambda-unc lysogen. All eight subunits co-purified in the same stoichiometric proportion as in the complex purified from wild type E. coli. We conclude that all eight subunits are likely coded by the small segment of chromosomal DNA carried by the lambda-transducing phage. These experiments provide the first evidence that all eight polypeptides are authentic subunits of the ATPase complex rather than contaminants that fortuitously co-purify.
Temporal solitary subpicosecond pulse propagation in a dye-doped polymer slab waveguide with a negative nonlinear refractive index (1998)

Subpicosecond (150 fs) temporal solitary pulse propagation is observed in an azo-dye-Disperse Red 1 doped (DR1) polymer waveguide. The negative nonlinear refractive index enables the generation of bright soliton in the medium with positive group velocity dispersion. Moreover, the pulse narrowing up to 97 fs based on the high-order soliton is observed. The magnitude of the nonlinear refractive index of the DR1-doped PMMA (poly[methyl methacrylate] film is estimated by cross-correlation measurement and the assumption-free pulse-form retrieval technique.

Regulation of pelZ, a gene of the pelB-pelC cluster encoding a new pectate lyase of Erwinia chrysanthemi 3937 (1996)

The phytopathogenic enterobacterium Erwinia chrysanthemi 3937 produces five major and several secondary endo-pectate lyases encoded by the pel genes. Most of these genes are arranged in clusters on the bacterial chromosome. The genomic region surrounding the pelB-pelC cluster was supposed to be involved in the regulation of PelB and PelC synthesis. We demonstrated that the variation of pelB expression resulted from the titration of a regulatory protein by the gene adjacent to pelC. This gene was renamed pelZ since it encodes a protein of 420 amino acids with an endo-pectate lyase activity. Regulation of pelZ expression was investigated by using transcriptional fusions and a study of mRNA synthesis. Its transcription depends on different environmental conditions. It is induced in planta and in the presence of pectic catabolite products. This induction seems to be partially mediated by the KdgR protein but does not result from a direct interaction of KdgR with the pelZ 5' region. The transcription of pelZ leads to the synthesis of a monocistronic mRNA. However, the synthesis of a polycistronic mRNA from the pelC promoter, regulated by KdgR, is responsible for increased production of PelZ under inducing conditions. pelZ transcription is also controlled by pecT, which regulates some other pel genes, but it is independent of the pecS regulatory locus. The pelZ gene appears to be widespread in different strains of E. chrysanthemi. Moreover, a gene homologous to pelZ exists in Erwinia carotovora subsp. atroseptica adjacent to the cluster containing the pectate lyase-encoding genes pel1, pel2, and pel3. This conservation could reflect a significant role of PelZ in the pectinolytic system of Erwiniae. We showed pelZ is not a predominant virulence factor of E. chrysanthemi but is involved in host specificity.
Center-related Bias in MELD Scores Within a Liver Transplant UNOS Region: A Call for Standardization (2019)

Despite implementation of creatinine standardization, centers within a single UNOS region report clinically significant differences in MELD-Na on an identical sample, with differences of up to 6 points in high MELD-Na patients. The bias in MELD-Na scores based upon center choice within a region should be addressed in the current efforts to eliminate disparities in liver transplant access.
Negative dispersion of birefringence in two-dimensionally self-organized smectic liquid crystal and monomer thin film (2014)

We suggest a method to obtain a negative dispersion (ND) of birefringence using a two-dimensional self-organization of smectic liquid crystal (LC) and monomer molecules. The averaged orientation of the smectic LC was the layer normal direction with the extraordinary refractive index n(e). Meanwhile, the orientation of the monomer molecules was templated by the host-smectic LC and parallel to the layer plane corresponding to the ordinary refractive index n(o). We selected the LC molecules absorbing a shorter wavelength of UV light rather than the polymerized monomers, hence n(e) was more smoothly decreased than n(o) in the visible-wavelength range. Consequently, the birefringence Δn≡n(e)-n(o) was increased with a longer wavelength, thus giving a ND of birefringence. Using the proposed method, the ND of birefringence could be obtained in a single layer, which is desirable for thin flexible applications.
Field-induced spirals from a confined cholesteric (1992)
