An Optimum Design Concept for Offshore Cage Culture (2012)

There is an overwhelming support to move aquaculture cages into offshore waters. Some of the key drivers for moving into offshore waters are limitation of available space near the coast, conflicts within as well as other coastal users, prospect of limitless expansion in offshore sites, the potential for optimum growth conditions and the need to reduce the production cost by increasing the scale of operation. Therefore, by using a set of requirements derived earlier by the authors, the paper looks into the current offshore cage designing concepts in order to propose an optimum design concept for offshore aquaculture. With the help of an expert panel, representing various disciplines which are important for fish farm development, the assessment point towards a single point mooring cage concept as the best option for offshore aquaculture farming. This concept is demonstrated by the use of simple geometric relations and graphs, showing the relation between the total horizontal forces, FH, vertical force component, FV, as the cage submerge. While the contribution from the current, FHC, to the total horizontal force, FH, is kept constant, the contribution from the waves to the total horizontal force, FH, (as assumed to be 33%) is subjected to a reduction proportional to the factor e2kz, representing the reduction in water particle velocity as a function of depth. Further, in light of the requirements derived through the major stakeholders, this paper also propose an alternative classification of cages into two major categories, i.e. systems that are intended to resist and dissipate environmental forces and system that are designed to avoid environmental forces.
A coordination framework for self-organisation in LTE networks (2011)

Self-organising Networks (SON) as introduced for 3G Long Term Evolution (LTE) will typically involve several different SON functions. These functions are not necessarily aware of each other and may have complex relations and interdependencies, for example, conflicting parameter settings, depending on their design and approach. Coordination of SON functions may become necessary in order to harmonise the actions of SON functions and allow for a stable and reliable behaviour of the SON system. This paper describes different conflict types, harmonisation approaches to avoid and resolve conflicts, and a functional framework with different roles to achieve harmonisation. An exemplary case study is given. The paper concludes that, in case several conflicting SON functions are implemented in a network, a SON Coordinator may be beneficial to prevent from network instabilities and/or to improve the performance.

Phytochemical analysis and evaluation of the antioxidant activity of edible green plants growing in Greece (2021)

The Mediterranean diet is renowned for its beneficial properties on human health, since it has been proven to contribute to decreased rates of heart disease, cancer and neurodegenerative diseases and therefore provides an excellent field for the discovery of new bioactive agents [1] [2]. Leafy green vegetables are an integral part of the Greek dietary regime. Herein, seven samples of plant species belonging to the family Compositae were studied for their content in bioactive compounds and antioxidant activity. Specifically, Centaurea raphanina, Cichorium intybus, Sonchus tenerrimus, Sonchus oleraceus and Sonchus asper were collected, extracted and analyzed for their chemical composition with HPTLC, HPLC-DAD and LC-MS. The plants possess a complex and interesting chemical profile, containing bioactive constituents, like flavonoids and phenolic acids. The extracts were evaluated for cytotoxicity and antioxidant activity by performing cell-based assays. All the
Holographic display system for restoration of sight to the blind (2013)

We address the issues associated with the design of high brightness, near-the-eye display systems and propose solutions to the efficiency and safety challenges with an optical design which could be miniaturized and mounted onto goggles.
Energy distributions of carriers in quantum dot laser structures (2004)

Using the segmented contact method, we have measured the passive modal absorption, modal gain and spontaneous emission spectra of an InAs “dot-in-well” (DWELL) system where the inhomogeneous broadening is sufficiently small that the ground and excited state transitions can be spectrally resolved. The modal optical gain from the ground state saturates with current at a maximum value of one third of the magnitude of the measured absorption. The population inversion factor spectrum, obtained from the measured gain and emission spectra, shows that the carrier distributions cannot be described by a single global Fermi distribution. However, the inversion factor spectrum can be described by a system where the ground state and excited state occupancies are each described by a Fermi distribution but with different quasi-Fermi energy separations.
Usefulness of the LigaSure™ small jaw sealing device for breast reconstruction with a latissimus dorsi flap (2019)

<b>Background:</b> Seromas are the most common complication of latissimus dorsi flap breast reconstruction. Electrocautery for flap elevation can cause seromas and injure the lymph or vessels of the surrounding tissues. Positive effects of the LigaSure Small Jaw (Medtronic [formerly Covidien], Minneapolis, MN, USA) sealing device were examined. <b>Methods:</b> Forty-three latissimus dorsi flap breast reconstruction patients were included. Twenty-three underwent surgery with electrocautery and 21 underwent surgery with LigaSure. The seroma formation rate, total drain volume, drainage indwelling periods at the breast site and donor site, operative time, and hospital stay duration were retrospectively compared. Associations between patient characteristics and these variables were analyzed. <b>Results:</b> Seroma incidence rates were 9/23 (39.1%) and 3/21 (14.3%) for the control and experimental groups. One control group patient underwent surgical treatment; the rest underwent conservative treatment. A significant difference in latissimus dorsi flap elevation time was found between the control and experimental groups (105.6 minutes and 77.1 minutes; <i>p</i> = .026). A significant difference in the drainage indwelling periods of the latissimus dorsi donor site was found (13.1 days and 11 days; <i>p</i> = .006). Excised breast mass weight, latissimus dorsi flap weight, breast drain total volume/indwelling period, and latissimus dorsi drain volume/indwelling period showed statistically significant associations. Radiation and chemotherapy were not significantly associated with any variables. <b>Conclusion:</b> The LigaSure device for latissimus dorsi flap breast reconstruction can reduce seromas, operative time, and hospital stay. It is a reliable and useful surgical sealing device that does not cause injury to the surrounding tissues.
Selective Photocleavage of DNA and RNA by Anthraquinone Derivatives: Targeting the Single‐Strand Region of Hairpin Structures (1999)

A tetracationic anthraquinone derivative (27AQS2) binds to hairpin DNA and RNA. Ultraviolet irradiation of the bound quinone causes cleavage in the loop region of both oligonucleotides and at guanines in the stem region of the DNA hairpin. The absence of observable strand cleavage at guanines in the RNA hairpin suggests that either aniline treatment does not cause cleavage at damaged guanines in RNA or that radical cation migration does not occur readily in RNA duplexes. The ability to target the single-stranded regions of DNA and RNA structures is an important property of this photonuclease.
Detection of capacitor degradation in LC filters for AC drives (2014)

Adjustable speed drives (ASDs) with regenerative PWM rectifiers - both voltage source rectifiers (VSR) and current source rectifiers (CSR) - have LC filters on their input to attenuate the high frequency components of current and achieve reduced levels of total harmonic distortion (THD). The capacitors used in these filters are predominantly of the metallized film construction and are prone to catastrophic failure. In this paper, a method is proposed for the detection of capacitor degradation and location of the faulted phase. The method uses measurements of voltages and currents - which may already be available for control purposes, for line synchronization and active damping - to detect impedance asymmetry, and is impervious to input voltage unbalance.
Nanosized Polymer Particle-facilitated Preparation of Mesoporous Silica Particles Using a Spray Method (2008)

Enhancing CRISPR-Cas-Mediated Detection of Nucleic Acid and Non-nucleic Acid Targets Using Enzyme-Labeled Reporters (2022)

We introduce a new method to generate an amplified signal in CRISPR-Cas-based detection. Target recognition activates a CRISPR-Cas complex, leading to catalytic cleavage of horseradish peroxidase (HRP)-labeled oligonucleotides from the surface of microbeads. We show that the HRP released into solution can be monitored through colorimetric, fluorometric, or luminescent approaches, yielding up to ∼75-fold turn-on signal and limits of detection (LODs) as low as ∼10 fM. Compared to Cas-based detection with a conventional fluorophore/quencher reporter, this strategy improves the LOD by ∼30-fold. As a proof-of-concept, we show the rapid (<1 h), PCR-free, and room temperature (25 °C) detection of a nucleic acid marker for the SARS-CoV-2 virus with the naked eye at clinically relevant concentrations. We further show that the probe set can be programmed to be recognized and activated in the presence of non-nucleic acid targets. Specifically, we show adenosine triphosphate (ATP) binding to an aptamer can activate CRISPR-Cas and trigger a colorimetric readout, enabling the analysis of ATP in human serum samples with sensitivity on par with that of several commercially available kits. Taken together, the strategy reported herein offers a simple and sensitive platform to detect analytes where target amplification is either inconvenient (e.g., PCR under point-of-care settings) or impossible.
Review of The Advancement of Learning: Building the Teaching Commons (2007)

Purpose The purpose of this paper is to provide a reflective evaluation of the concept of the teaching commons as presented by authors Huber and Hutchings and to summarize expected outcomes from participation therein. Design/methodology/approach An appraisal of the book The Advancement of Learning: Building the Teaching Commons is presented to explore the conception of the teaching commons. This review addresses the definition of the teaching commons and explores the establishment of, and participation in, the teaching commons as a means of advancing the scholarship of teaching and learning and for improving student learning. Findings A fundamental premise is developed suggesting that the development and utilization of a teaching commons will improve teaching and learning through the provision of a defined safeplace for conversations about teaching and learning and specific avenues to share information about teaching innovations for improving student learning. Sustained faculty engagement in a teaching commons must be supported by formalized institutional recognition and appropriate rewards. Practical implications A practical resource for faculty members involved in the scholarship of teaching and learning and for administrators developing teaching and learning centers or resources for utilization by faculty members. Originality/value This review examines the definition and establishment of a teaching commons for improving the scholarship of teaching and learning at the college and university levels.
Intestinal bypass for morbid obesity: a consecutive personal series. (1980)

Forty-five patients who underwent end-to-side jejunoileal bypass, with 51 cm in circuit, were followed up from 8 months to 8 years (average 3.4 years). There was no early or late mortality but morbidity was considerable; it included inadequate weight loss or late gain in 22%, malnutrition and liver failure in 11%, severe diarrhea and electrolyte imbalance in 11%. Cholelithiasis and wound complications also occurred. Reanastomosis was necessary in 13% (six patients). The result of the bypass was good in only 20%, satisfactory in 44% and unsatisfactory in 36%. This type of bypass is not adequate treatment for morbid obesity because the proportion of unsatisfactory results (36%) is too high and the number of good results too low and because the outcome is unpredictable. The complication of malnutrition characterized by a decline in body cell mass, an expansion of the extracellular mass and an increase in the ratio of total exchangeable sodium to total exchangeable potassium is quickly and effectively treated by intravenous administration of amino acids or protein hydrolysates. Long-term management of protein malnutrition requires a high protein diet (100 g/d) or reanastomosis.
Green light generation by QPM SHG with Czochralski-grown stoichiometric lithium tantalate (2005)

Using periodically-poled stoichiometric lithium tantalate, peak power of 21.6 MW/cm/sup 2/ at 532 nm was achieved. A small temperature adjustment was required with 4.4 W SH power at room temperature due to its high thermal conductivity.
DC-DC buck converter design: a sampled-data approach (2006)

Direct sampled-data design techniques which use "lifting" concepts that capture the periodic structure of the sampled data system in order to obtain a tractable optimization problem that accommodates meaningful (weighted H <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">infin</sup> ) closed loop performance specifications as well as sample rate and intersample behavior is proposed. Direct sampled-data design controller has similar complexity as discretized classical designs but operates at a much lower sampling rate. FPGA implementation data is presented for each design. Comparisons demonstrating the benefits of the sampled-data approach in achieving reasonable trade-offs are presented
Deep unsupervised learning using nonequilibrium thermodynamics (2024)

A central problem in machine learning involves modeling complex data-sets using highly flexi-ble families of probability distributions in which learning, sampling, inference, and evaluation are still analytically or computationally tractable. Here, we develop an approach that simultane-ously achieves both flexibility and tractability. The essential idea, inspired by non-equilibrium statistical physics, is to systematically and slowly destroy structure in a data distribution through an iterative forward diffusion process. We then learn a reverse diffusion process that restores structure in data, yielding a highly flexible and tractable generative model of the data. This ap-proach allows us to rapidly learn, sample from, and evaluate probabilities in deep generative models with thousands of layers or time steps, as well as to compute conditional and posterior probabilities under the learned model. We addi-tionally release an open source reference imple-mentation of the algorithm. 1.
7.2 A 28GHz 32-element phased-array transceiver IC with concurrent dual polarized beams and 1.4 degree beam-steering resolution for 5G communication (2017)

Next-generation mobile technology (5G) aims to provide an improved experience through higher data-rates, lower latency, and improved link robustness. Millimeter-wave phased arrays offer a path to support multiple users at high data-rates using high-bandwidth directional links between the base station and mobile devices. To realize this vision, a phased-array-based pico-cell must support a large number of precisely controlled beams, yet be compact and power efficient. These system goals have significant mm-wave radio interface implications, including scalability of the RFIC+antenna-array solution, increase in the number of concurrent beams by supporting dual polarization, precise beam steering, and high output power without sacrificing TX power efficiency. Packaged Si-based phased arrays [1-3] with nonconcurrent dual-polarized TX and RX operation [2,3], concurrent dual-polarized RX operation [3] and multi-IC scaling [3,4] have been demonstrated. However, support for concurrent dual-polarized operation in both RX and TX remains unaddressed, and high output power comes at the cost of power consumption, cooling complexity and increased size. The RFIC reported here addresses these challenges. It supports concurrent and independent dual-polarized operation in TX and RX modes, and is compatible with a volume-efficient, scaled, antenna-in-package array. A new TX/RX switch at the shared antenna interface enables high output power without sacrificing TX efficiency, and a t-line-based phase shifter achieves <;1° RMS error and <;5° phase steps for precise beam control.
Involvement of outer membrane of Pseudomonas cepacia in aminoglycoside and polymyxin resistance (1986)

Pseudomonas cepacia was found to be resistant to the outer membrane-permeabilizing effects of aminoglycoside antibiotics, polymyxin B, and EDTA. Permeabilization of P. cepacia to the fluorescent probe 1-N-phenylnaphthylamine was not achieved at concentrations 100- to 1,000-fold above those required to permeabilize Pseudomonas aeruginosa. Furthermore, in contrast to P. aeruginosa cells, intact cells of P. cepacia did not bind the fluorescent probe dansyl-polymyxin. However, purified lipopolysaccharide (LPS) from P. cepacia bound dansyl-polymyxin with approximately the same affinity as did LPS from P. aeruginosa. Also, binding of dansyl-polymyxin to P. cepacia (and P. aeruginosa) LPS was inhibited by polymyxin B, streptomycin, gentamicin, and Mg2+. These data suggest that P. cepacia does not utilize the self-promoted pathway for aminoglycoside uptake and that the outer membrane is arranged in a way that conceals or protects cation-binding sites on LPS which are capable of binding polycations such as aminoglycosides or polymxyin.

Controlled Methodology for Development of a Polydimethylsiloxane–Polytetrafluoroethylene-Based Composite for Enhanced Chemical Resistance: A Structure–Property Relationship Study (2020)

Polydimethylsiloxane (PDMS) polymers are highly appreciated materials that are broadly applied in several industries, from baby bottle nipples to rockets. Momentive researchers are continuously working to understand and expand the scope of PDMS-based materials. Fluorofunctional PDMS has helped the world to apply in specialty applications. Efforts are taken to develop such siloxane-fluoropolymer composite materials with good thermal, solvent, and chemical resistance performances. We leveraged inherently flexible PDMS as the model matrix, whereas polytetrafluoroethylene (PTFE) was used as the additive to impart the functional benefits, offering great value in comparison to the individual polymers. The composites were made at three different mixing temperatures, that is, 0-35 °C, and different loadings of PTFE, that is, 0.5-8% (w/w), were selected as the model condition. A strong dependency of the mixing temperature against the performance attributes of the developed composites was noted. Mechanical and thermal stability of the composites were evaluated along with optical properties. X-ray diffraction demonstrated the change in the crystallite size of the PTFE particles as a function of processing temperature. Compared to the phase II crystallite structure of the PTFE, the fibrils formed in phase IV imparted a better reinforcing capability toward the PDMS matrix. A synergistic balance between higher filler loading and mechanical properties of the composite can be achieved by doping the formulation with short-chain curable PDMS, with 238% increment of tensile strength at 8 wt % PTFE loading when compared to the control sample. The learning was extended to check the applicability of doping such PTFE powder in commercial liquid silicone rubber (LSR). In the window of study, the formulated LSR demonstrated improved mechanical properties with additional functional benefits like resistance toward engine oil and other chemical solvents.

Multilateral servo control for haptic communication (2008)

Artificial acquisition and reproduction of human sensations are basic technologies of communication engineering. For example, auditory information is obtained by a microphone, and a speaker reproduces it by artificial means. Furthermore, a video camera and a television make it possible to transmit visual sensation by broadcasting. On the contrary, since tactile or haptic information is subject to the Newton’s “law of action and reaction” in the real world, a device which acquire, transmit, and reproduce the information has not been established.
Diamond Photonics (2015)

Diamond possesses remarkable physical and chemical properties, and in many ways is the ultimate engineering material. For example, it is transparent from the ultra-violet to infrared, has a high refractive index (n = 2.4), strong optical nonlinearity (Kerr and Raman) and a wide variety of light-emitting defects. These properties make diamond a highly desirable material for many applications, including those in quantum and nonlinear photonics.
Bio-organic chemistry and cytochrome P-450-dependent catalysis (1984)

This review presents current ideas, models and experimental data relating to the precise chemistry that links the transition metal active centre of cytochrome P-450 systems, the unactivated alkane substrate and the triplet atmospheric dioxygen molecule. Aspects considered include the hypervalent transition metal, the reductive activation of the dioxygen molecule by two electrons as an intermediate in the four-equivalent oxidase mechanism, and the details of carbon-hydrogen and carbon-carbon fragmentation. Studies of the microbial camphor 5-exo hydroxylase system are used to exemplify the principles discussed.
