Inelastic quasiparticle scattering andT1−1NQR relaxation rate inPr1−xLaxOs4Sb12 (2008)

We present an analysis of recent [M. Yogi et al., J. Phys. Soc. Jpn. 75, 124702 (2006)] Sb-NQR measurements of the heavy-fermion superconductor ${\text{PrOs}}_{4}{\text{Sb}}_{12}$ and the related La-doped series of superconductors ${\text{Pr}}_{1\ensuremath{-}x}{\text{La}}_{x}{\text{Os}}_{4}{\text{Sb}}_{12}$. We find that this data, along with previous temperature-dependent superfluid density results and are well described by a strong-coupling order parameter containing a doping-dependent proportion of the first cubic harmonic $({k}_{x}^{4}+{k}_{y}^{4}+{k}_{z}^{4})$ component along with an $s$-wave component, when inelastic scattering due to Coulomb effects are taken into account. The resulting gap function has deep minima along the cubic axis [100], etc. but no nodes. We use the order parameter fits to generate, within the Ginzburg--Landau theory, the effective thermal mass enhancement relative to the ${\text{LaOs}}_{4}{\text{Sb}}_{12}$ material and find that it rapidly varies for small $x$.
A micro Tesla turbine for power generation from low pressure heads and evaporation driven flows (2011)

We report on the design, fabrication and testing of a low pressure head Tesla microturbine. We began developing this technology as a means of scavenging energy from fluids flows induced in plant-like evaporative systems. Unlike traditional inertial turbines, Tesla turbines have high efficiency when driven with low pressure flows, are relatively simple to manufacture and scale down very favorably. The 1 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> rotor diameter turbine presented here is, to our knowledge, the smallest Tesla turbine reported, with an unloaded peak power of 45 mW (12 cc/sec flow, 17% efficiency) and a peak efficiency of 40% (<; 2 cc/sec flow). Moreover, the entire turbine is built using a variety of modern commercial rapid prototyping methods, making its construction accessible to almost anyone. Beyond applications in evaporative scavenging, Tesla microturbines may find use as components in ultrasmall-profile heat engines and for energy generation from sources of low pressure head flow.
Image compression using multilayer neural networks (1997)

A new neural-network data compression method is presented. The work extends the use of two-layer neural networks to multilayer networks. Results show the performance superiority of multilayer neural networks compared with that of the two-layer one, especially at high compression ratios. To overcome the long training time required for multilayered networks, a recently developed training algorithm has been used. A modfied feedback error is proposed to reduce further the training time and to enhance the image quality. Also, a redistribution of the grey levels in the training phase is proposed to make the minimisation of the mean-square error more related to the human-vision system.
List Decoding of Universal Polar Codes (2020)

A list decoding scheme for universal polar codes is presented. Our scheme applies to the universal polar codes first introduced by ŗaşoğlu and Wang, and generalized to processes with memory by the authors. These codes are based on the concatenation of different polar transforms: a sequence of "slow" transforms and Arıkan's original "fast" transform. List decoding of polar codes has been previously presented in the context of the fast transform. However, the slow transform is markedly different and requires new techniques and data structures. We show that list decoding is possible with space complexity O(L·N) and time complexity O(L·Nlog N), where N is the overall blocklength and L is the list size.

FNDC-1-mediated mitophagy and ATFS-1 coordinate to protect against hypoxia-reoxygenation (2021)

Mitochondrial quality control (MQC) balances organelle adaptation and elimination, and mechanistic crosstalk between the underlying molecular processes affects subsequent stress outcomes. FUNDC1 (FUN14 domain containing 1) is a mammalian mitophagy receptor that responds to hypoxia-reoxygenation (HR) stress. Here, we provide evidence that FNDC-1 is the <i>C. elegans</i> ortholog of FUNDC1, and that its loss protects against injury in a worm model of HR. This protection depends upon ATFS-1, a transcription factor that is central to the mitochondrial unfolded protein response (UPRmt). Global mRNA and metabolite profiling suggest that <i>atfs-1</i>-dependent stress responses and metabolic remodeling occur in response to the loss of <i>fndc-1</i>. These data support a role for FNDC-1 in non-hypoxic MQC, and further suggest that these changes are prophylactic in relation to subsequent HR. Our results highlight functional coordination between mitochondrial adaptation and elimination that organizes stress responses and metabolic rewiring to protect against HR injury.<b>Abbreviations:</b> AL: autolysosome; AP: autophagosome; FUNDC1: FUN14 domain containing 1; HR: hypoxia-reperfusion; IR: ischemia-reperfusion; lof: loss of function; MQC: mitochondrial quality control; PCA: principle component analysis; PPP: pentonse phosphate pathway; proK (proteinase K);UPRmt: mitochondrial unfolded protein response; RNAi: RNA interference.

Cloning and Sequence Analysis of a cDNA for 3-Hydroxyisobutyrate Dehydrogenase (1989)

A 1.7-kilobase pair cDNA clone encoding 3-hydroxyisobutyrate dehydrogenase has been isolated by screening a rat liver lambda gt11 library with a 17-base oligonucleotide probe which corresponds to a portion of the N-terminal amino acid sequence of rabbit liver 3-hydroxyisobutyrate dehydrogenase. The cDNA contains an open reading frame of 1038 base pairs which includes an amino acid sequence that matches the N-terminal 35 amino acid sequence of rabbit 3-hydroxyisobutyrate dehydrogenase at 33 residues. The cDNA predicts a 300-amino acid mature protein with an amino acid composition and molecular weight very similar to that of rabbit liver 3-hydroxyisobutyrate dehydrogenase. Northern blot analysis of total RNA from several rat tissues shows an mRNA of approximately 2.0 kilobase pairs in each tissue. Relative mRNA levels were: kidney greater than liver = heart greater than muscle. The amino acid sequence of 3-hydroxyisobutyrate dehydrogenase shows similarity to several other pyridine nucleotide-dependent dehydrogenases. The resemblance to malate and lactate dehydrogenases suggests that the nucleotide-binding domain is located in the N-terminal region of the protein.

Diet, commensal microbiota‐derived extracellular vesicles, and host immunity (2023)

The gut microbiota has co-evolved with its host, and commensal bacteria can influence both the host's immune development and function. Recently, a role has emerged for bacterial extracellular vesicles (BEVs) as potent immune modulators. BEVs are nanosized membrane vesicles produced by all bacteria, possessing the membrane characteristics of the originating bacterium and carrying an internal cargo that may include nucleic acid, proteins, lipids, and metabolites. Thus, BEVs possess multiple avenues for regulating immune processes, and have been implicated in allergic, autoimmune, and metabolic diseases. BEVs are biodistributed locally in the gut, and also systemically, and thus have the potential to affect both the local and systemic immune responses. The production of gut microbiota-derived BEVs is regulated by host factors such as diet and antibiotic usage. Specifically, all aspects of nutrition, including macronutrients (protein, carbohydrates, and fat), micronutrients (vitamins and minerals), and food additives (the antimicrobial sodium benzoate), can regulate BEV production. This review summarizes current knowledge of the powerful links between nutrition, antibiotics, gut microbiota-derived BEV, and their effects on immunity and disease development. It highlights the potential of targeting or utilizing gut microbiota-derived BEV as a therapeutic intervention.
A Late Mitotic Regulatory Network Controlling Cyclin Destruction inSaccharomyces cerevisiae (1998)

Exit from mitosis requires the inactivation of mitotic cyclin-dependent kinase-cyclin complexes, primarily by ubiquitin-dependent cyclin proteolysis. Cyclin destruction is regulated by a ubiquitin ligase known as the anaphase-promoting complex (APC). In the budding yeast Saccharomyces cerevisiae, members of a large class of late mitotic mutants, including cdc15, cdc5, cdc14, dbf2, and tem1, arrest in anaphase with a phenotype similar to that of cells expressing nondegradable forms of mitotic cyclins. We addressed the possibility that the products of these genes are components of a regulatory network that governs cyclin proteolysis. We identified a complex array of genetic interactions among these mutants and found that the growth defect in most of the mutants is suppressed by overexpression of SPO12, YAK1, and SIC1 and is exacerbated by overproduction of the mitotic cyclin Clb2. When arrested in late mitosis, the mutants exhibit a defect in cyclin-specific APC activity that is accompanied by high Clb2 levels and low levels of the anaphase inhibitor Pds1. Mutant cells arrested in G1 contain normal APC activity. We conclude that Cdc15, Cdc5, Cdc14, Dbf2, and Tem1 cooperate in the activation of the APC in late mitosis but are not required for maintenance of that activity in G1.
IETF Multi-Protocol Label Switching (MPLS) Transport Profile (MPLS-TP) Document Process (2010)

The decision to develop a Multiprotocol Label Switching (MPLS)
Transport Profile (MPLS-TP) in cooperation between the IETF and the
ITU-T is document in RFC 5317 as the decision of the Joint Working
Team on MPLS-TP. This document provides additional detail of the
processes for the development of IETF RFCs on MPLS-TP. It provides an
adaptation of the IETF working group process; identifies the expected
participation in the process by the ITU-T; and clarifies the rules and
conventions regarding MPLS-TP documents. This document does not
specify any ITU-T process; ITU-T activities will be done according to
ITU-T process/rules. This document does not specify or modify the
normal IETF working group process. It is limited to the specific
adaptations of that process to facilitate the cooperation agreement
between the IETF and the ITU-T on MPLS-TP, and to ensure a good and
consistent document review across the two organizations. This
document is a product of a joint Internet Engineering Task Force
(IETF) / International Telecommunication Union Telecommunication
Standardization Sector (ITU-T) effort to include an MPLS Transport
Profile within the IETF MPLS and PWE3 architectures to support the
capabilities and functionalities of a packet transport network.
A multicentre trial of Zostrum (5 percent idoxuridine in dimethyl sulphoxide) in herpes zoster. (1981)

Forty-six patients with herpes zoster were randomised into two groups treated with DMSO alone and 5 percent IDU in DMSO, provided that treatment started within 48 hours of the appearance of a rash. In the IDU group the interval before pain improved was significantly shorter than in the control DMSO group, and significantly fewer new vesicles developed at the three day follow up in the active group compared with the control group. These findings are in agreement with previously published work and confirm the usefulness of Zostrum (5 percent IDU in DMSO) in the treatment of herpes zoster.

Object by value transfer mechanisms for obligation policy enforcement object loading (2004)

Adequate architecture and technology can significantly improve the adaptability and performance of the policy-based management systems. We present how the policy enforcement point operation can be improved by applying the "object by value" transfer mechanisms. Policy enforcement object transferred and loaded into the policy enforcement point as a stateful object can support the adaptable behaviour of the point. We experimented with the two standard object by using the value technologies such as CORBA valuetypes and Java serialization on RMl. Examples in this paper refer to the CORBA valuetypes only.
ATP Hydrolysis Is Essential for the Function of the Uup ATP-binding Cassette ATPase in Precise Excision of Transposons (2006)

In Escherichia coli K-12, the RecA- and transposase-independent precise excision of transposons is thought to be mediated by the slippage of the DNA polymerase between the two short direct repeats that flank the transposon. Inactivation of the uup gene, encoding an ATP-binding cassette (ABC) ATPase, led to an important increase in the frequency of precise excision of transposons Tn10 and Tn5 and a defective growth of bacteriophage Mu. To provide insight into the mechanism of Uup in transposon excision, we purified this protein, and we demonstrated that it is a cytosolic ABC protein. Purified recombinant Uup binds and hydrolyzes ATP and undergoes a large conformational change in the presence of this nucleotide. This change affects a carboxyl-terminal domain of the protein that displays predicted structural homology with the socalled little finger domain of Y family DNA polymerases. In these enzymes, this domain is involved in DNA binding and in the processivity of replication. We show that Uup binds to DNA and that this binding is in part dependent on its carboxyl-terminal domain. Analysis of Walker motif B mutants suggests that ATP hydrolysis at the two ABC domains is strictly coordinated and is essential for the function of Uup in vivo.
Rapid and Low-Cost CRP Measurement by Integrating a Paper-Based Microfluidic Immunoassay with Smartphone (CRP-Chip) (2017)

Traditional diagnostic tests for chronic diseases are expensive and require a specialized laboratory, therefore limiting their use for point-of-care (PoC) testing. To address this gap, we developed a method for rapid and low-cost C-reactive protein (CRP) detection from blood by integrating a paper-based microfluidic immunoassay with a smartphone (CRP-Chip). We chose CRP for this initial development because it is a strong biomarker of prognosis in chronic heart and kidney disease. The microfluidic immunoassay is realized by lateral flow and gold nanoparticle-based colorimetric detection of the target protein. The test image signal is acquired and analyzed using a commercial smartphone with an attached microlens and a 3D-printed chip-phone interface. The CRP-Chip was validated for detecting CRP in blood samples from chronic kidney disease patients and healthy subjects. The linear detection range of the CRP-Chip is up to 2 μg/mL and the detection limit is 54 ng/mL. The CRP-Chip test result yields high reproducibility and is consistent with the standard ELISA kit. A single CRP-Chip can perform the test in triplicate on a single chip within 15 min for less than 50 US cents of material cost. This CRP-Chip with attractive features of low-cost, fast test speed, and integrated easy operation with smartphones has the potential to enable future clinical PoC chronic disease diagnosis and risk stratification by parallel measurements of a panel of protein biomarkers.

Audiometric outcomes in revision stapes surgery (2022)

There are many possible reasons for performing a revision stapes surgery after previous middle ear interventions. From the audiological point of view persistent or progressive conductive hearing loss is the main indication. Because revision surgery is generally considered as having poorer hearing results and more complications, it is important to define the audiological improvement potential of the patient.
Electroconductive Biohybrid Hydrogel for Enhanced Maturation and Beating Properties of Engineered Cardiac Tissues (2018)

Abstract Cardiac tissue engineering is a promising strategy to treat heart failure. Yet, several issues remain to be resolved including the prevention of arrhythmia caused by inefficient electrical coupling within the graft and between graft and host tissue. Here, a biohybrid hydrogel composed of collagen, alginate, and electroconductive poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) is developed that exhibits extracellular matrix–mimetic fibrous structures and enhanced electrical coupling as well and cardiomyocyte maturation. Presence of PEDOT:PSS in the hydrogel improves electrical conductivity and prevents arrhythmia of tissue constructs containing neonatal rat cardiomyocytes. Moreover, it results in increasing beating frequencies reaching more than 200 beats min −1 endogenous frequencies. In addition, cardiomyocytes exhibit increased alignment and density in these constructs, improved sarcomere organization, and enhanced connexin 43 expression, suggesting maturation of the cardiac tissue. Importantly, the here developed electroconductive biohybrid hydrogels also improve maturation and beating properties of human‐induced pluripotent stem cell–derived cardiomyocytes. These cells exhibit 1.9 µm near adult sarcomeric length, enhanced beating frequency, increased speed of contraction, and larger contraction amplitude. Collectively, the data demonstrate the potential of this electroconductive biohybrid hydrogel to improve tissue engineering approaches to treat heart failure and possibly diseases of other electrically sensitive tissues.
Eucalyptus cinerea and E. nicholii by-Products as Source of Bioactive Compounds for Agricultural Applications (2022)

The cultivation of different species of <i>Eucalyptus</i> has recently expanded in Liguria (Italy) due to the growing demand of the North European floricultural market. Eucalyptus tree branches are cut and selected for their quality, resulting in large amounts of waste biomass to be disposed of. The aim of our study was to evaluate the phytotoxic and antimicrobial activities of essential oils (EOs) from pruning wastes of <i>E. cinerea</i> (EC) and <i>E. nicholii</i> (EN), for potential applications in agriculture. Phytochemical analyses showed eucalyptol (1,8-cineole) as the major component in both EOs, but the EO yield of EN was higher than that of EC, in agreement with a significantly higher oil gland density on EN leaves. EOs from both species showed phytotoxicity on both weeds tested, but no significant inhibition on horticultural crop seed germination, except for <i>Raphanus sativus</i>. The EO from EC showed the strongest antibacterial activity, while the EO from EN showed the strongest antifungal activity. Concluding, EOs from <i>Eucalyptus</i> pruning may be used as possible alternatives to synthetic herbicides and pesticides, acting as antimicrobial and antifungal agents, thus representing a safe strategy for crop management programs.
