A case of central nervous system lupus in succession to lupus peritonitis: a difficulty in the differential diagnosis between lupus psychosis and steroid-induced psychosis (2004)

Abstract A 55-year-old woman with well-controlled systemic lupus erythematosus (SLE) suffered from the abrupt onset of massive intractable ascites, which did not respond to conventional diuretic therapy. While treatment with methylprednisolone pulse therapy ameliorated this lupus peritonitis, neuropsychiatric symptoms then appeared. After a diagnosis of the central nervous system (CNS) lupus, pulse therapy was continued and the patient recovered from the lupus psychosis. We discuss the differential diagnosis between CNS lupus and steroid-induced psychosis with particular references to recent diagnostic methods for CNS lupus.
Structure of yeast phenylalanine transfer RNA at 2.5 A resolution. (1975)

The x-ray analysis of the monoclinic form of yeast tRNAPhe has been taken to a resolution of 2.5 A by the method of isomorphous replacement. The model proposed at 3 A has been confirmed and extended to reveal additional features of the tertiary structure and of the stereochemistry. An extensive hydrogen bonding network is described involving specific interactions between bases and the ribose-phosphate backbone. The structure of a G-U base pair has been solved.
Acido polilattico (PLA): miglioramento delle proprietà barriera e sviluppo di compositi ecosostenibili (2014)

Co-administration of gut-active supplements (e.g. pro- and pre-biotics), innovative drug delivery vehicles, and strategic polypharmacy serve as the most promising and clinically viable approaches for controlling pharmacomicrobiomic interactions. Targeting the gut microbiome through these strategies presents new opportunities for improving therapeutic efficacy by precisely mediating PK/PD, while mitigating metabolic disturbances caused by drug-induced gut dysbiosis. However, successfully translating preclinical potential into clinical outcomes relies on overcoming key challenges related to interindividual variability in microbiome composition and study design parameters.

The improvement over previously achieved efficiencies is the result of cell design and fabrication changes made in response to detailed quantitative modeling and analysis of the cell operation.
A multi-lane MIPI CSI receiver for mobile camera applications (2010)

In this paper, we present a multi-lane Mobile Industry Processor Interface (MIPI) Camera Serial Interface (CSI) receiver which is suitable for high-resolution camera and High-Density (HD) video applications. The presented receiver is designed to achieve parallel processing so that it reduces dynamic power consumption for multi-lane configuration. In order to facilitate parallel processing, we propose two techniques for the multi-lane receiver. The presented design receives data at the maximum rate of 4Gb/s and is verified in a standard CMOS technology.

Charge Separation by Collision of Ice Particles on Metals: Electronic Surface States (1978)

Abstract The charge separation of ice particles colliding with metals was investigated in a wind tunnel (air speed 10 m/s) at a temperature of —45°C for different metals as a function of an applied external electric field. The ice particles (to μm radius) collided with the metal target at a rate of 10 5 per second. The charge separation produced by different metals can be explained by the contact potential difference between the metal and the ice introducing electronic surface states on the ice. A lower limit for their density (10 16 m –2 ) is found. The influence of the electric field is explained by an interaction between Bjerrum defects and the electrons of the metal, the transfer probability depending on the charge in the surface states.

Reversible and Specific Extracellular Antagonism of Receptor-Histidine Kinase Signaling (2002)

Staphylococcal pathogenesis is regulated by a two-component quorum-sensing system, agr, activated by a self-coded autoinducing peptide (AIP). The agr system is widely divergent and is unique in that variant AIPs cross-inhibit agr activation in heterologous combinations. Cross-inhibition, but not self-activation, is widely tolerant of structural diversity in the AIPs so that these two processes must involve different mechanisms of interaction with the respective receptors. Herein, we have utilized this naturally occurring antagonism to demonstrate that both activation and inhibition are reversible and that activators and inhibitors interact at a common site on the receptor. These results suggest that molecules designed to compete with natural agonists for binding at receptor-histidine kinase sensor domains could represent a general approach to the inhibition of receptor-histidine kinase signaling.

Enhancement-mode n-channel GaN MOSFETs with overlap gate structure using thick HfO2 as a gate insulator have been fabricated. The maximum transconductance of 45 mS/mm is seven times larger, to our knowledge, than the best-reported value of GaN MOSFETs with SiO2 gate oxide.
Laugh Away the Fat? Therapeutic Humor in the Control of Stress-induced Emotional Eating (2014)

This review explores the potential overlap between the fields of nutrition and therapeutic humor, together with the role of humor as a possible tool for aiding those in whom emotions, particularly negative ones, trigger eating as a means to improve mood. We review emotional eating, obesity, and the hypothesized mechanisms of emotional eating. We then review the field of therapeutic humor and its ability to de-stress individuals, possibly through endorphin and opioid systems, both of which are also involved in eating behavior. Finally, we present a novel hypothesis that people may be trained to use humor as a "food substitute" at best, or to blunt hunger stimuli, to achieve similar advantages, without the side effect of weight gain.
Contactless electrostatic handling of microcomponents (2004)

Microdevices are every day becoming more sophisticated and flexible. Common manufacturing techniques based on semiconductor technology do not fully meet the requirements brought up by the development of new applications or the necessity of increased performances in actual systems. In order to obtain three-dimensional structures with high mechanical properties, new manufacturing approaches based on the exploitation of different materials are necessary and the assembly of these microparts becomes a key issue to solve. In the assembly process, because of the low mass of the microcomponents, adhesive forces (surface tension, van der Waals and electrostatic attraction) cause the component to stick, with the gripper making the releasing phase very complex. Therefore microassembly requires new handling techniques such as, for example, electrostatic contactless handling, which appears to be very promising. Through a comparative analysis between theoretical results and simulations, the electrostatic forces on which the alignment and movement of microparts is based have been estimated and a demonstrative device has been designed and tested. In this paper electrostatic contactless handling is discussed, the developed prototype is presented and the feasibility of the transportation and positioning of mini- and micro-objects (as predicted by theory) is demonstrated through a set of experiments.
The “Missing” Bicarbonate in CO2 Chemisorption Reactions on Solid Amine Sorbents (2018)

We have identified a hydrated bicarbonate formed by chemisorption of <sup>13</sup>CO<sub>2</sub> on both dimethylaminopropylsilane (DMAPS) and aminopropylsilane (APS) pendant molecules grafted on SBA-15 mesoporous silica. The most commonly used sequence in solid-state NMR, <sup>13</sup>C CPMAS, failed to detect bicarbonate in these solid amine sorbent samples; here, we have employed a Bloch decay ("pulse-acquire") sequence (with <sup>1</sup>H decoupling) to detect such species. The water that is present contributes to the dynamic motion of the bicarbonate product, thwarting CPMAS but enabling direct <sup>13</sup>C detection by shortening the spin-lattice relaxation time. Since solid-state NMR plays a major role in characterizing chemisorption reactions, these new insights that allow for the routine detection of previously elusive bicarbonate species (which are also challenging to observe in IR spectroscopy) represent an important advance. We note that employing this straightforward NMR technique can reveal the presence of bicarbonate that has often otherwise been overlooked, as demonstrated in APS, that has been thought to only contain adsorbed CO<sub>2</sub> as carbamate and carbamic acid species. As in other systems (e.g., proteins), dynamic species that sample multiple environments tend to broaden as their motion is frozen out. Here, we show two distinct bicarbonate species upon freezing, and coupling to different protons is shown through preliminary <sup>13</sup>C-<sup>1</sup>H HETCOR measurements. This work demonstrates that bicarbonates have likely been formed in the presence of water but have gone unobserved by NMR due to the nature of the experiments most routinely employed, a perspective that will transform the way the sorption community will view CO<sub>2</sub> capture by amines.
An improved technique to reduce peak to average power ratio in OFDM systems using gold/hadamard codes with selective mapping (2014)

Despite its many advantages for high data rate transmission over frequency selective channels, one of the challenging issues faced by orthogonal frequency division multiplexing (OFDM) system is its high peak to average power ratio (PAPR). Selective mapping (SLM) is an efficient technique to reduce PAPR in OFDM without causing signal distortion. However SLM has high system complexity since it requires large number of inverse fast Fourier transform (IFFT) operations. And also it demands the transmission of side information for each data block which results in huge bandwidth overhead. In this paper, we propose an improved SLM technique with either Gold or Hadamard code which ensures low system complexity to achieve the same PAPR reduction performance as that of conventional SLM. Also the proposed SLM method promises superior PAPR reduction compared to that of conventional SLM for identical system complexities. Moreover, the proposed SLM approach needs less side information to be send to the receiver resulting in improved bandwidth efficiency. Simulation studies show that considerable reduction in PAPR than conventional SLM method is achieved for identical number of multiplying phase sequences. The effect of non-linear distortion caused by high PAPR is also studied and the proposed method is shown to ensure linear operation over a large dynamic range of high power amplifier (HPA) in an OFDM transmitter.
Static and Dynamic Functional Visual Fields (1979)

The size of visual field utilized by the human visual system to input information about the outside world was investigated for static and dynamic viewing conditions. In static conditions, subjects detected a target that was presented in a peripheral position while maintaining central fixation. The size depended greatly on the imposed task: a large field to detect a spot of light, a small field to distinguish a target from background noise, and a still smaller field to distinguish a target from background noise while detecting a figure in the central visual field. In the dynamic condition, subjects read sentences or perceived pictures with restricted sizes of visual field and a critical field size was determined which assured normal perceptual behaviour. The size was about 10° visual angle in both cases, which was quite large compared to the saccadic size of the eye movement, implying a need to input the entire pattern for a limited time. Reasons for such short inputting times are discussed.
Edge-Wise Gated Graph Neural Network for User Association in Massive URLLC (2021)

To support ultra-reliable and low-latency communications with massive connections, we develop a novel user association algorithm in mobile edge computing with grant-free random access based on an edge-wise gated graph neural network (EG-GNN). The parameters of the EG-GNN are trained in an unsupervised manner by minimizing the overall packet loss probability, including the decoding error probability of short packet transmissions, the collision probability of random access, and the processing delay violation probability in edge servers. By representing the wireless network by a bipartite graph with base station nodes and device nodes, we apply the EG-GNN to user association, where the "gate" of an edge is defined as the probability that a device will associate with a BS. The values gates are determined by a fully connected neural network at each device node. To improve the training efficiency, analytical results in wireless communications and queueing theory are exploited to update node features. Simulation and analytical results demonstrate that the proposed EG-GNN approach outperforms existing benchmarks in terms of overall reliability with linear complexity.

Collaboration is the key for urology (2016)

The patient always comes first. How do we do this better in urology? Firstly, by offering world-class treatment options from diagnosis through to survivorship. Secondly, by participating and leading research projects that will have an impact on better care. Finally, by debating and analyzing real data, taking on board constructive criticisms and by not accepting dogma. We should not be afraid to question technologies be they surgical or radiation-based and nor should we be afraid of questioning the efficacy of drugs and their benefits. In questioning we learn and clarify and the best way to question is to analyze the data, the research but also the costs- emotional and even financial. Collaboration means a wider arc even than the traditional multi-disciplinary tumour meetings that includes urologists (surgical oncologists), urology nurse specialists, radiologists, pathologists, radiation oncologists, medical oncologists as well as allied health. We must reach deeper to include general practitioners with better communication and shared care which has just been highlighted with the publication of the ProCare Trial 1. This randomized Australian trial demonstrated that well-structured shared care for men with low- to moderate-risk prostate cancer is feasible and appears to produce clinically similar outcomes to those of standard care- but at a lower cost. Finally, we must continue to engage with support groups and the wider community. How do we collaborate more effectively? By having leadership from our organizations that represents the memberships of those organizations. ANZUP (Australian and New Zealand Urogenital and Prostate Cancer Trials Group.) It has been particularly effective in this regard. We may also create new organizations. The relatively new YURO group (Young Urology Researchers Organization) is one such example where people from different regions are coming together to contribute to great research 2. This will be expanded to all branches of care and is open to students through to more senior doctors. Again, tools such as social media have proven to be effective vehicles in propagating messages and connecting people internationally 3. Further initiatives such as the Australian National Prostate Cancer Registry as well as the development of the bi-national Nephrectomy Audit (as part of the [Urological Society of Australia and New Zealand [USNAZ] Urological Surgery Registry) are to be applauded. Clinicians must maintain control and direction of the data to be used appropriately and not hijacked by interest groups. As leaders in Surgical Oncology urologists may also expand such data ownership and collection to the vast non-oncological care that is provided. So let us all see the bigger picture and remember that we are all interested in the same outcomes.
Mimicking the end organ architecture of slowly adapting type I afferents may increase the durability of artificial touch sensors (2014)

In effort to mimic the sensitivity and efficient information transfer of natural tactile afferents, recent work has combined force transducers and computational models of mechanosensitive afferents. Sensor durability, another feature important to sensor design, might similarly capitalize upon biological rules. In particular, gains in sensor durability might leverage insight from the compound end organ of the slowly adapting type I afferent, especially its multiple sites of spike initiation that reset each other. This work develops models of compound spiking sensors using a computational network of transduction functions and leaky integrate and fire models (together a spike encoder, the software element of a compound spiking sensor), informed by the output of an existing force transducer (hardware sensing elements of a compound spiking sensor). Individual force transducer failures are simulated with and without resetting between spike encoders to test the importance of both resetting and configuration on system durability. The results indicate that the resetting of adjacent spike encoders, upon the firing of a spike by any one, is an essential mechanism to maintain a stable overall response in the midst of transducer failure. Furthermore, results suggest that when resetting is enabled, the durability of a compound sensor is maximized when individual transducers are paired with spike encoders and multiple, paired units are employed. To explore these ideas more fully, use cases examine the design of a compound sensor to either reach a target lifetime with a set probability or determine how often to schedule maintenance to control the probability of failure.
Magnetic Bubble Research. (1974)

Abstract : This report contains three principal sections corresponding to Tasks I, II, and III outlined in Proposal No. 18-R72, 6 September 1972. Section 1 is addressed to the conceptual aspects of using bubble devices for data processing which includes logic and memory. During the reporting period a specific requirement, data processing for space satellite attitude control, was chosen as a model for defining the necessary attributes for a bubble data processor. These attributes appear to be consistent with our analysis of the potential capabilities of bubble devices in terms of size, weight, power and data rate. The model suggests some specific logic requirements which will be translated into device hardware in the remaining months of the contract. Section 11 treats the hybrid technologies, bubble/optical guided wave interactions and bubble/elastic wave interactions. This work is behind schedule with regard to experimentation, but the conceptual aspects are well advanced. Several device concepts are presented in the report. Key to the success of these hybrid technologies are the strengths of the interactions. These interactions will be studied during the next reporting period. The results will determine whether or not to proceed to develop either hybrid technology under Task 111. Section 111 of the report deals with progress on ion-implant devices and Permalloy circuits for submicrometer diameter bubbles (small-bubbles). The small-bubble work is behind schedule, but progress is being made. Progress on ion-implant circuits has not been as rapid as initial results on the early devices would have indicated.
Autonomous Removal of Perspective Distortion for Robotic Elevator Button Recognition (2019)

Elevator button recognition is considered an indispensable function for enabling the autonomous elevator operation of mobile robots. However, due to unfavorable image conditions and various image distortions, the recognition accuracy remains to be improved. In this paper, we present a novel algorithm that can autonomously correct perspective distortions of elevator panel images. The algorithm first leverages the Gaussian Mixture Model (GMM) to conduct a grid fitting process based on button recognition results, then utilizes the estimated grid centers as reference features to estimate camera motions for correcting perspective distortions. The algorithm performs on a single image autonomously and does not need explicit feature detection or feature matching procedure, which is much more robust to noises and outliers than traditional feature-based geometric approaches. To verify the effectiveness of the algorithm, we collect an elevator panel dataset of 50 images captured from different angles of view. Experimental results show that the proposed algorithm can accurately estimate camera motions and effectively remove perspective distortions.
Side-scattered finger-photoplethysmography: experimental investigations toward practical noninvasive measurement of blood glucose (2017)

The aim of this study was to discover a simple/convenient geometrical arrangement of radiation sources and detector to acquire finger-photoplethysmograms (PPGs) with wavelength regions of blood glucose (BGL) absorption, toward practical noninvasive BGL measurement. First, we compared PPGs with three wavelengths: 808 nm (without water absorption), 1160 nm (with weak water absorption), and 1600 nm (with nearly peak BGL absorption and strong water absorption), while the source-detector spacing was successively increased circumferentially around a fingertip. In 10 healthy subjects, we observed clear cardiac-related pulsatile components of PPG signals at 808 and 1160 nm in any incident positions with more than 15 dB of signal-to-noise ratio ( S / N ), but reliable PPG detections at 1600 nm with more than 10 dB of S / N was only possible when the source-detector distance was less than 3 mm around the fingertip circumference. Second, with this arrangement, an experiment was performed using six wavelengths to cover glucose absorption bands (from 1550 to 1749 nm), obtaining pulsatile PPG signals with more or less 15 dB of S / N . Through the present experiments, this orthogonal arrangement of the source and detector to detect forward- and side-scattered radiation through the tissue is appropriate for PPG measurements with wavelength regions where there is potential for BGL measurement.
