Topology Optimization Based Design of Lightweight and Low Vibration Gear Bodies (2018)

This article presents a new approach aiming to reduce gear vibration and weight by modifying its body structure. The primary objective was to reduce vibration and noise emission of spur gears. For this purpose, a solid gear body was replaced by a lattice structure, which was expected to raise the torsional compliance of the body. The lattice structure was configured and optimized by a FE-based topology optimization software. For experimental purposes, the optimized gear was produced from Titanium alloy Ti-6Al-4V ELI using Selective Laser Melting technique. In the tests, the sound pressure of various running gear pairs was measured in order to estimate and compare the properties of a solid gear, of a lattice gear, and of a lattice gear, filled with polymer to increase the structural damping. It was experimentally confirmed that the cellular lattice structure of a gear body and addition of a polymer matrix may significantly reduce the vibration.
Pyrometallurgical Recovery of Gallium from GaN Semiconductor through Chlorination Process Utilizing Ammonium Chloride (2017)

Pyrometallurgical chlorination process has been examined for the recovery of gallium from gallium nitride, GaN, a promising semiconductor material. It was found that gallium was successfully recovered as volatile gallium chloride by thermal treatment of GaN powder in the presence of ammonium chloride. All gallium could be recovered as volatile species at 500℃. The results indicate that gallium can be extracted from complex mixture of semiconductor materials or wastes through this process. The influence of reaction conditions, such as reaction temperature and composition of ammonium chloride, was examined.

Silicon Models for Auditory Scene Analysis. (1995)

We are developing special-purpose, low-power analog-to-digital converters for speech and music applications, that feature analog circuit models of biological audition to process the audio signal before conversion. This paper describes our most recent converter design, and a working system that uses several copies of the chip to compute multiple representations of sound from an analog input. This multi-representation system demonstrates the plausibility of inexpensively implementing an auditory scene analysis approach to sound processing.
Evidence for long-living charge carriers in electrically biased low-temperature-grown GaAs photoconductive switches (2007)

Low-temperature-grown GaAs continues to be one of the most important materials of ultrafast optoelectronics. Little is known, however, about the recombination dynamics of photogenerated charge carriers under the influence of an applied electric field, and it has remained unclear to what extent biased photoswitches exhibit field screening effects. Here, the authors investigate the screening in biased few-micrometer-sized photoconductive gaps quantitatively and find that it can amount to tens of percent of the applied field. They find that a subgroup of the photogenerated carriers recombines on an unexpectedly long excitation-density-dependent time scale of nanoseconds to tens of nanoseconds.
Activity of the C. elegans egg-laying behavior circuit is controlled by competing activation and feedback inhibition (2016)

Abstract Like many behaviors, Caenorhabditis elegans egg laying alternates between inactive and active states. To understand how the underlying neural circuit turns the behavior on and off, we optically recorded circuit activity in behaving animals while manipulating circuit function using mutations, optogenetics, and drugs. In the active state, the circuit shows rhythmic activity phased with the body bends of locomotion. The serotonergic HSN command neurons initiate the active state, but accumulation of unlaid eggs also promotes the active state independent of the HSNs. The cholinergic VC motor neurons slow locomotion during egg-laying muscle contraction and egg release. The uv1 neuroendocrine cells mechanically sense passage of eggs through the vulva and release tyramine to inhibit egg laying, in part via the LGC-55 tyramine-gated Cl − channel on the HSNs. Our results identify discrete signals that entrain or detach the circuit from the locomotion central pattern generator to produce active and inactive states.

Integration of Catalytic Biofuel Production and Anaerobic Digestion for Biogas Production (2021)

Abstract The drive towards a low carbon economy will lead to an increase in new lignocellulosic biorefinery activities. Integration of biorefinery waste products into established bioenergy technologies could lead to synergies for increased bioenergy production. In this study, we show that solid residue from the acid hydrolysis production of levulinic acid, has hydrochar properties and can be utilised as an Anaerobic Digestion (AD) supplement. The addition of 6 g/L solid residue to the AD of ammonia inhibited chicken manure improved methane yields by +14.1%. The co-digestion of biorefinery waste solids and manures could be a promising solution for improving biogas production from animal manures, sustainable waste management method and possible form of carbon sequestration.
Cold drawn steel wires—processing, residual stresses and ductility—part I: metallography and finite element analyses (2006)

ABSTRACT Cold drawing steel wires lead to an increase of their mechanical strength and to a drop of their ductility. The increase of their mechanical strength has long been related to the reduction of the various material scales by plastic deformation, but the mechanisms controlling their elongation to failure have received relatively little attention. It is usually found that heavily deformed materials show a tendency to plastic strain localization and necking. However, in this paper it is shown that, though the steel wires are plastically deformed up to strain levels as high as 3.5, a significant capability of plastic deformation is preserved in as‐drawn wires. This apparent contradiction is resolved by the existence of residual stresses inside the wire. Finite element analyses have been conducted in order to show that residual stresses, inherited from the drawing process, are sufficient to produce a significant hardening effect during a post‐drawing tensile test, without introducing any hardening in the local material behaviour. The main conclusion of this paper is that once the material has lost its hardening capabilities, residual stresses, inherited from the process, control the elongation of cold drawn wires. The finite element method allowed also the determination of the residual stress field that would lead to the best agreement between the simulated and the experimental stress strain curve of as‐drawn wires.
The cost of confusion: healthcare reform and value-based purchasing. (2010)

Title III of the Affordable Care Act presents two types of opportunities: those whose outcomes pose some uncertainties and those whose outcomes are well known. Accountable care organizations (ACOs) represent an uncertain opportunity, and although they may prove to be a worthwhile pursuit, focus on ACOs should generally not take precedence over more pressing concerns, such as impending loss of Medicare revenue. Value-based purchasing represents an opportunity that, if missed, would likely result in a revenue loss.
Study on photoluminescence and Raman scattering of GaInP and AlInP grown by organometallic vapor-phase epitaxy (1988)

The photoluminescence and Raman scattering spectra of GaInP and AlInP grown by organometallic vapor-phase epitaxy are measured to investigate the ordered and disordered crystalline states. It is found that ordered structure exists not only in the GaInP but also in the AlInP, and probably in the entire AlGaInP system, and that zinc doping over 1018 cm−3 makes it disordered. This disordering effect is attributed to the Zn diffusion in the GaInP epilayer during crystal growth which puts the once-formed ordered atomic arrangement into a disordered state.
Emergent Languages from Pretrained Embeddings Characterize Latent Concepts in Dynamic Imagery (2020)

Recent unsupervised learning approaches have explored the feasibility of semantic analysis and interpretation of imagery using Emergent Language (EL) models. As EL requires some form of numerical embedding as input, it remains unclear which type is required in order for the EL to properly capture key semantic concepts associated with a given domain. In this paper, we compare unsupervised and supervised approaches for generating embeddings across two experiments. In Experiment 1, data are produced using a single-agent simulator. In each episode, a goal-driven agent attempts to accomplish a number of tasks in a synthetic cityscape environment which includes houses, banks, theaters and restaurants. In Experiment 2, a comparatively smaller dataset is produced where one or more objects demonstrate various types of physical motion in a 3D simulator environment. We investigate whether EL models generated from embeddings of raw pixel data produce expressions that capture key latent concepts (i.e. an agent’s motivations or physical motion types) in each environment. Our initial experiments show that the supervised learning approaches yield embeddings and EL descriptions that capture meaningful concepts from raw pixel inputs. Alternatively, embeddings from an unsupervised learning approach result in greater ambiguity with respect to latent concepts.

A REFINEMENT OF THE EXTERNAL FRONTOETHMOSPHENOID OPERATION: A NEW NASOFRONTAL PEDICLE FLAP (1936)

When an external operation for the treatment of suppuration of the frontal sinus fails it is usually for one of two reasons. Either the opening into the nose becomes inadequate or disease is left in supraorbital ethmoid extensions with continuance of symptoms. In 1898 Lothrop<sup>1</sup>reported a study of the surgical anatomy of the frontal sinuses. Almost everything that has since been written on the subject can be found in this paper. He pointed out that the full extent of the nasal portion of the floor of the frontal sinus is not used because of thick bone anteriorly and medially. In 1914<sup>2</sup>he read a paper describing an operation he had used with satisfactory results in many cases. The method, reported more fully later,<sup>3</sup>provided a large opening into the nose by removing the interfrontal septum, all the nasal portion of the floor of both
Live shopping promotions: which categories should a retailer discount to shoppers already in the store? (2022)

Abstract Digitalization allows retailers to target customers with personalized promotions when they enter the store. Although traditional promotional retailer objectives, such as store visit, become obsolete once the shopper is already in the store, retailers still tend to target customers based on indicators that drive store visit, such as recency, frequency, and monetary value (RFM). In order to improve promotional efficiency, the authors propose targeting shoppers based on information derived from regularity patterns in individual interpurchase times at the point of sale. When compared to RFM-based targeting, the proposed live targeting approach translates into higher redemption rates (+ 10.5 percentage points), revenues (+ 42.3 percentage points), and purchase frequencies (+ 44.2 percentage points). The findings emphasize the importance of promotional timing and of considering customers’ outside potential for dynamic in-store targeting.
Method for Interfacing a Plate Reader Spectrometer Directly with an OT-2 Liquid Handling Robot (2022)

The Opentrons OT-2 liquid handling robot is a powerful instrument available at an affordable price, yet due to the limited accessories available cannot perform some functions of more expensive liquid handling robots, such as the automated transfer of plates to a spectrometer for analysis. Here, we describe the hardware and software necessary to interface a commercial UV-Vis plate reader with an OT-2, allowing the liquid handling robot to directly aspirate or deposit into a 96-well plate located on the plate reader.

Comparison of asphere measurements by tactile and optical metrological instruments (2015)

A comparison of topography measurements of aspherical surfaces was carried out by European metrology institutes, other research institutes and a company as part of an European metrology research project. In this paper the results of this comparison are presented. Two artefacts were circulated, a small polymer coated aspherical lens with a clear aperture of about 12 mm, and a large conical convex lens with a clear aperture of 300 mm developed for the ESO Very Large Telescope. The participating laboratories were allowed to follow their own measurement strategies. Both tactile and optical measuring instruments were used, as well as single point and imaging techniques. The measured data were compared with respect to the root-mean-square (RMS), peak-to-valley and Zernike polynomial representations of the measured deviations from the nominal shape. The comparison shows for five out of eight measuring instruments/methods a very good agreement of the measured topographies within 14 nm (RMS).

Comprehensive determination of transcription start sites derived from all RNA polymerases using ReCappable-seq (2021)

Determination of eukaryotic transcription start sites (TSSs) has been based on methods that require the cap structure at the 5' end of transcripts derived from Pol II RNA polymerase. Consequently, these methods do not reveal TSSs derived from the other RNA polymerases that also play critical roles in various cell functions. To address this limitation, we developed ReCappable-seq, which comprehensively identifies TSS for both Pol II and non-Pol II transcripts at single-nucleotide resolution. The method relies on specific enzymatic exchange of 5' m<sup>7</sup>G caps and 5' triphosphates with a selectable tag. When applied to human transcriptomes, ReCappable-seq identifies Pol II TSSs that are in agreement with orthogonal methods such as CAGE. Additionally, ReCappable-seq reveals a rich landscape of TSSs associated with Pol III transcripts that have not previously been amenable to study at genome-wide scale. Novel TSS from non-Pol II transcription can be located in the nuclear and mitochondrial genomes. ReCappable-seq interrogates the regulatory landscape of coding and noncoding RNA concurrently and enables the classification of epigenetic profiles associated with Pol II and non-Pol II TSS.
Joint throughput and channel aware (TCA) dynamic scheduling algorithm for emerging wearable applications (2016)

This paper addresses a reliability concern of the emerging wearable applications under dynamic and realistic conditions. We propose a new joint throughput and channel aware (TCA) dynamic scheduling algorithm for IEEE 802.15.6 standard to enhance the system performance while exploiting m-periodic scheduled access mechanism. First, various mobility patterns are generated with special emphasis on space and time varying links and their performance which are most vulnerable under dynamic environment. A deterministic pathloss values (as an estimate of the channel) are obtained from a set of training sequence which is generated using motion capture system and bio-mechanical modeling. Consequently, signal to noise (SNR), bit error rate (BER) and packet error rate (PER) are calculated. The TCA algorithm during the first phase uses this estimated PER to select the potential nodes for a time slot. Whereas in the second phase, based on the nodes priority and the data packets availability among the potential candidates, finally a slot is assigned to one node. This process is repeated by the coordinating node until the end of the super frame. This scheme has a significant gain over a reference scheme (i.e., without above adaptation). On average, 20-to-55 percent extra packets are received, along with 1-to-5 joules of energy savings though at the cost of higher delay ranging from 20-to-200 ms while operating at low power levels (i.e., 0 dBm, -5 dBm, -10 dBm).
Communication in Bacteria (2005)

Bacteria communicate with one another using chemical signal molecules. As in higher organisms, the information supplied by these molecules is critical for synchronizing the activities of large groups of cells. In bacteria, chemical communication involves producing, releasing, detecting, and responding to small hormone-like molecules termed autoinducers. This process, termed quorum sensing, allows bacteria to monitor the environment for other bacteria and to alter behavior on a population-wide scale in response to changes in the number and/or species present in a community. Most quorumsensing-controlled processes are unproductive when undertaken by an individual bacterium acting alone but become beneficial when carried out simultaneously by a large number of cells. Thus, quorum sensing confuses the distinction between prokaryotes and eukaryotes because it enables bacteria to act as multicellular organisms. This review focuses on the architectures of bacterial chemical communication networks; how chemical information is integrated, processed, and transduced to control gene expression; how intra- and interspecies cell-cell communication is accomplished; and the intriguing possibility of prokaryote-eukaryote cross-communication.
Effects of day-time feeding on murine skeletal muscle growth and synthesis (2019)

Muscle mass is controlled by the balance between muscle synthesis and degradation. Although nutrition is important for the maintenance of muscle mass and growth, the effects of feeding time have remained unclear. In the present study, we aimed to evaluate the effects of day- or night-time-restricted feeding on the muscle volume using muscle atrophy and hypertrophy mouse models. The day- and night-time-restricted feeding was conducted from zeitgeber time 2 (ZT2) to ZT10 and ZT14 to ZT22, respectively. In the unilateral immobilization-induced atrophy model, the decrease in immobilized muscle weight did not significantly change with the feeding time. However, the contralateral non-immobilized muscle weight was lower in the mice fed at day time (inactive phase) than in those fed at night time (active phase). In the overloading-induced hypertrophy model, muscle hypertrophy and protein synthesis were attenuated by day-time feeding. These results suggest that day-time feeding attenuated muscle growth via the inhibition of muscle synthesis. Feeding at an irregular time such as a late-night meal could be detrimental for muscle growth.
COMPARISON OF SOME CONTENT-BASED IMAGE RETRIEVAL SYSTEMS WITH ROCK TEXTURE IMAGES (2002)

Texture is commonly used feature in most of the content-based image retrieval systems. This texture retrieval ability can be also applied to rock texture. The retrieval of the rock texture is a demanding task because of special character of rock. In this paper some existing contentbased image retrieval systems are tested with a sample set representing clearly different rock images. The recall ability of these systems is measured based on the retrieval experiments. Texture retrieval has also been made using some well-known classifying features, which are extracted from the textures. The extracted features are based on second order statistics (cooccurrence matrix) and texture directionality. These features proved to be powerful in the sample texture retrieval.
