Signal Estimation from Modified Short-Time (1984)

In this paper, we present an algorithm to estimate a signal from its modified short-time Fourier transform (STFT). This algorithm is computationally simple and is obtained by minimizing the mean squared error between the STFT of the estimated signal and the modi- fied STFT. Using this algorithm, we also develop an iterative algorithm to estimate a signal from its modified STFT magnitude. The iterative algorithm is shown to decrease, in each iteration, the mean squared error between the STFT magnitude of the estimated signal and the modified STFT magnitude. The major computation involved in the iterative algorithm is the discrete Fourier transform (DFT) computa- tion, and the algorithm appears to be real-time implementable with current hardware technology. The algorithm developed in this paper has been applied to the time-scale modification of speech. The result- ing system generates very high-quality speech, and appears to be better in performancc than any existing method.

Characterization of a hybrid plasma and its application to a chemical synthesis (1983)

A numerical model has been developed for predicting the two-dimensional flow and temperature fields in a hybrid plasma which is characterized by the superposition of an rf plasma and an arc jet. Calculations have been made for the confirmation of a prominent feature of the hybrid plasma. As might be expected, the derived results suggested that the hybrid plasma has a possibility to offer higher efficiencies for practical processing than other conventional plasmas. Particularly noteworthy is the disappearance of a recirculation eddy found in a usual rf plasma, by the presence of the high velocity and high-temperature channel caused by an arc jet flow. Moreover, the relative insensitive character of the exit gas enthalpy to the rf input power was found. Based on the theoretical investigations, a reactor was designed to confirm the effectiveness of the hybrid plasma for chemical syntheses. Using the reactor, ultrafine amorphous Si3N4 with the nitrogen content of 37±0.5 wt. % and the size of 10–30 nm, which can meet the purity and size requirements of an ideal Si3N4 powder, could be prepared successfully by a reaction of SiCl4 and NH3. These theoretical and experimental investigations confirmed that the hybrid plasma torch is an effective reactor for the preparation of ultrafine refractory compounds by plasma chemical vapor deposition (CVD) processes.
A modified smith predictor with an approximate inverse of dead time (1990)

Abstract A compensator that approximates the inverse of dead time at low frequencies in a modified Smith predictor (MSP) control system is proposed, and the design of an MSP control system for it is given. The performance of the MSP with compensator, using a first‐order element as a low‐pass filter, is described. Analysis and simulation results show that the compensator improves performance in the disturbance rejection of the original Smith predictor.
Insulin and insulinlike growth factor 1 (IGF-1) receptors during central nervous system development: expression of two immunologically distinct IGF-1 receptor beta subunits. (1989)

Insulin and insulinlike growth factor 1 (IGF-1) receptors are present in brain, yet their function remains obscure. Expression of these tyrosine kinase-bearing growth factor receptors during rat brain development was examined by using three antipeptide antibodies directed against epitopes in the beta subunits (AbP2, AbP4, and AbP5). All three antibodies recognized both insulin and IGF-1 receptors. Membranes were prepared from fetal brains (14 to 21 days of gestation), neonatal brain (postnatal day 1), and adult brain. Immunoblot analyses using AbP4 and AbP5 revealed a 92-kilodalton (kDa) protein that corresponded to the beta subunit of the insulin and IGF-1 receptors. Densitometric scanning of immunoblots indicated that receptor proteins were 4- to 10-fold more abundant in fetal brain membranes than in membranes from adult brain. Expression was highest during 16 to 18 days of gestation and declined thereafter to the relatively low level found in adult brain. Immunoblot analyses with AbP2 as well as ligand-activated receptor autophosphorylation revealed an additional protein of 97 kDa. This protein was phosphorylated in response to IGF-1 and was not directly recognized by AbP4 or AbP5. The covalent association of the 97-kDa protein with the 92-kDa beta subunit was indicated by the ability of AbP4 and AbP5 to immunoprecipitate both proteins under nonreducing conditions but only the 92-kDa protein after reduction. In contrast, AbP2 immunoprecipitated both proteins regardless of their association. This immunospecificity remained unchanged after deglycosylation of the isolated proteins. Two-dimensional tryptic phosphopeptide analysis showed that the 92- and 97-kDa subunits of the IGF-1 receptor are related but distinct proteins. Taken together, the data suggest that the 92- and 97-kDa subunits differ in primary amino acid sequence. Thus, two distinct beta subunits may be present in a single IGF-1 receptor in brain. These subunits have in common an epitope recognized by an antibody to the tyrosine kinase domain (AbP2) but differ in regions thought to be important in receptor kinase regulation and signal transduction.
Differentiation of human induced pluripotent stem cells to authentic macrophages using a defined, serum-free, open-source medium (2021)

Human induced pluripotent stem cells (iPSCs) and macrophages derived from them are increasingly popular tools for research into both infectious and degenerative diseases. However, as the field strives for greater modeling accuracy, it is becoming ever more challenging to justify the use of undefined and proprietary media for the culture of these cells. Here, we describe a defined, serum-free, open-source medium for the differentiation of iPSC-derived macrophages. This medium is equally capable of maintaining these cells compared with commercial alternatives. The macrophages differentiated in this medium display improved terminally differentiated cell characteristics, reduced basal expression of induced antiviral response genes, and improved polarization capacity. We conclude that cells cultured in this medium are an appropriate and malleable model for tissue-resident macrophages, on which future differentiation techniques can be built.
Near-infrared diffuse optical monitoring of cerebral blood flow and oxygenation for the prediction of vasovagal syncope (2014)

Significant drops in arterial blood pressure and cerebral hemodynamics have been previously observed during vasovagal syncope (VVS). Continuous and simultaneous monitoring of these physiological variables during VVS is rare, but critical for determining which variable is the most sensitive parameter to predict VVS. The present study used a novel custom-designed diffuse correlation spectroscopy flow-oximeter and a finger plethysmograph to simultaneously monitor relative changes of cerebral blood flow (rCBF), cerebral oxygenation (i.e., oxygenated/deoxygenated/total hemoglobin concentration: r[HbO2]/r[Hb]/rTHC), and mean arterial pressure (rMAP) during 70 deg head-up tilt (HUT) in 14 healthy adults. Six subjects developed presyncope during HUT. Two-stage physiological responses during HUT were observed in the presyncopal group: slow and small changes in measured variables (i.e., Stage I), followed by rapid and dramatic decreases in rMAP, rCBF, r[HbO2], and rTHC (i.e., Stage II). Compared to other physiological variables, rCBF reached its breakpoint between the two stages earliest and had the largest decrease (76±8%) during presyncope. Our results suggest that rCBF has the best sensitivity for the assessment of VVS. Most importantly, a threshold of ∼50% rCBF decline completely separated the subjects from those without presyncope, suggesting its potential for predicting VVS.
Effect of elastane linear density on compression pressure of V-shapedcompression socks (2018)

The aim of this study was to evaluate the effect of elastane material linear densities on lateral compression values (ankle and calf) in newly designed shape (V-shape) compression socks. For this purpose, three types of yarns: main yarn (MY), plating yarn (PY) and inlaid yarn (IY) were used. Each yarn contains elastane material as core with varying linear densities. Firstly, Machine adjustments were optimized to achieve special V-shaped compression socks according to fix leg size. All the yarns were installed simultaneously and evaluated for their impact on compression pressure value at different segments of leg. Total eighteen socks samples were developed and quantified for pressure exertion using MST MKIV, Salzmann pressure monitoring device. All samples were analyzed using ANOVA in MINTAB 16 software. Consequently, only two socks samples finalized acquiring pressure exertion values of 21 mmHg and 23 mmHg with graduation percentage of 76% and 74% simultaneously
Role of stromal cell-derived factor 1α pathway in bone metastatic prostate cancer (2016)

Metastatic prostate cancer is one of the leading causes of cancer-related death in men. The primary site of metastasis from prostate cancers is the bone. During the last decade, multiple studies have pointed to the role of the stromal cell-derived factor 1 alpha (SDF1α)/CXCR4 axis in the metastatic spread of the disease, but the mechanisms that underlie this effect are still incompletely understood. In this review, we summarize the current understanding of the role of the SDF1α/CXCR4 pathway in bone metastatic prostate cancer. We also discuss the therapeutic potential of disrupting the interaction between prostate tumor cells and bone environment with focus on the SDF1α pathway.
A Pseudo-Blind Convolutional Neural Network for the Reduction of Compression Artifacts (2019)

This paper presents methods based on convolutional neural networks (CNNs) for removing compression artifacts. We modify the Inception module for the image restoration problem and use it as a building block for constructing blind and non-blind artifact removal networks. It is known that a CNN trained in a non-blind scenario (known compression quality factor) performs better than the one trained in a blind scenario (unknown factor), and our network is not an exception. However, the blind system is more practical because the compression quality factor is not always available or does not reflect the actual quality when the image is a transcoded or requantized image. Hence, in this paper, we also propose a pseudo-blind system that estimates the quality factor for a given compressed image and then applies a network that is trained with a similar quality factor. For this purpose, we propose a CNN that estimates the compression quality factor and prepare several non-blind artifact removal networks that are trained for some specific compression quality factors. We train the networks and conduct experiments on widely used compression standards, such as JPEG, MPEG-2, H.264, and HEVC. In addition, we conduct experiments for dynamically changing and transcoded videos to demonstrate the effectiveness of the quality estimation method. The experimental results show that the proposed pseudo-blind network performs better than the blind one for the various cases stated above and requires fewer computations.
Anti‐Ice Coating Inspired by Ice Skating (2014)

Accumulation of ice to surfaces brings dangerous and costly problems to our daily life. In this paper, an anti-ice coating inspired by ice skating is reported. Hyaluronic acid is used in the anti-ice coating to form aqueous lubricating layer benefitting from its high water absorbing property. Dopamine, the main component of the mussel adhesive protein, is introduced to anchor the hyaluronic acid to the solid surfaces to render the coating applicable to all types of solid surfaces. At the same time it serves as the crosslinking agent for hyaluronic acid, thus the thickness of the water collecting film could be easily varied. Ice adhesion strength on surfaces coated with such kind of coating could be more than one order of magnitude lower than that of uncoated ones. The results indicate that this anti-ice coating with the aqueous lubricating layer has great potential for fighting against icing problems.
Impact Properties of Silica Particle Modified Glass Fiber Reinforced Epoxy Composite (2006)

The glass fiber (GF) reinforced epoxy composite samples used in this study are prepared by four different standardized methods, designated as Methods A, B, C, and D. The GF that is modified with silica particles and prestressed during curing in the composite system (Method D) is proved to be significantly superior as a potential candidate material for use in high impact applications. The impact property of the so-finished composite samples is compared, in turn, with other composite samples prepared by the other methods. There are clean fiber reinforced epoxy composite (Method A), modified GF reinforced epoxy composite (Method B), and prestressed clean GF reinforced epoxy composite (Method C). The results indicate that the impact property of the composites prepared by this novel Method D is greater by up to 100% in comparison with Method A and by lesser but, significant, amounts by the other two methods.
Development of a BACnet-ZigBee gateway for demand response in buildings (2013)

Smart Grid (SG) is a modernized and a future-oriented electric grid that deals with the whole energy chain from generation to consumer. Among SG applications, demand response (DR) is an important control mechanism to manage the electricity consumption of the customer in response to the supply condition. In buildings, DR is managed through communication networks installed in the buildings. These communication protocols must include DR-supporting applications. BACnet (Building automation and control network) is an international standard communication protocol for building automation and control systems (BACS). BACnet uses ZigBee as a wireless communication protocol for BACS. Both BACnet and ZigBee have their own DR applications. In this study, we developed a BACnet-ZigBee gateway that maps the DR application of BACnet to that of ZigBee. The function of the BACnet-ZigBee gateway was verified through experiment.

The Dynamics of Microwave-Assisted Magnetic Recording (2015)

Models of microwave-assisted magnetic recording are used to investigate the potential of the technology. With both single- and double-layer [exchange coupled composite (ECC)] media, the higher effective head field gradient led to reduced transition jitter and higher SNR in written tracks. To reduce the high-frequency field to a realistic frequency range, the use of ECC media is required. However, the ECC medium design must consider interactions between the spin torque oscillator and the medium.
The role of ion channels in insulin secretion (1992)

Ion channels in beta cells regulate electrical and secretory activity in response to metabolic, pharmacologic, or neural signals by controlling the permeability to K+ and Ca2+. The ATP-sensitive K+ channels act as a switch that responds to fuel secretagogues or sulfonylureas to initiate depolarization. This depolarization opens voltage-dependent calcium channels (VDCC) to increase the amplitude of free cytosolic Ca2+ levels ([Ca2+]i), which triggers exocytosis. Acetyl choline and vasopressin (VP) both potentiate the acute effects of glucose on insulin secretion by generating inositol 1,4,5-trisphosphate to release intracellular Ca2+; VP also potentiates sustained insulin secretion by effects on depolarization. In contrast, inhibitors of insulin secretion decrease [Ca2+]i by either hyperpolarizing the beta cell or by receptor-mediated, G-protein-coupled effects to decrease VDCC activity. Repolarization is initiated by voltage- and Ca(2+)-activated K+ channels. A human insulinoma voltage-dependent K+ channel cDNA was recently cloned and two types of alpha 1 subunits of the VDCC have been identified in insulin-secreting cell lines. Determining how ion channels regulate insulin secretion in normal and diabetic beta cells should provide pathophysiologic insight into the beta cell signal transduction defect characteristic of non-insulin dependent diabetes (NIDDM).
The process of implementing an ISO 9001 quality management system in a school of nursing. (2000)

This paper documents the process undertaken during the establishment of an ISO 9000 series quality management system by a School of Nursing. Further discussion centres around the reasons why an ISO quality management system was implemented, the lessons learnt during the process and the benefits that accreditation has brought to the School of Nursing. The lessons learnt during the process could be of help to other organisations wishing to achieve a similar accreditation status.
Reverse Engineering of Graphical User Interfaces (2011)

This paper describes a dynamic reverse engineering approach and a tool (ReGUI) that were developed with the aim of reducing the effort to obtain a visual and formal model of the structure and behaviour of a software applications GUI. Once produced, the model must be completed, checked and validated to ensure that it faithfully describes the intended system. These models are used as a test oracle and as input to a test case generation tool in the context of the AMBER iTest project, in which model based testing techniques are applied with GUI testing purposes.

Selective stimulation and recording using a slanted multielectrode array (2003)

The authors have developed a neural interface, the Utah Slant Array (the USA), that provides unprecedented access to a large number of sensory and motor neurons. The array has been designed to be implanted into fascicles of peripheral nerves, and it provides up to 100 channels of neural communication. The authors are currently evaluating the recording and stimulation capabilities of the USA in acute experiments in cat sciatic nerve. Very high selectivity even for high forces can be reached by near simultaneous stimulation of two or more electrodes innervating the same muscles. The authors suspect that, using the same methods, fatigue resistant stimulation is also possible.
Ultrastructure of Mechanically Deboned Poultry Meat (1974)

Mechanically deboned poultry meat (MDPM) is a communiated meat product produced by deboning poultry parts like backs and necks. The production of this product has been steadily increasing and represents an additional source of animal protein. The physical and chemical properties of the product have been well characterized by Grunden (1972), Froning et al. (1971), Schnell (1972), and Vadehra and Baker (1970). The poor shelf life has been explained on the basis of lipid degradation by Grunden et al. (1971), Dimick et al. (1972) and Rattrie (1973). The meat is exposed to considerable stress during the deboning process. This study was conducted to determine the effect of the deboning process on the ultrastructure of the MDPM.
The CAT's and Full University Status (1960)

In the September issue Sir David Anderson said of the Colleges of Advanced Technology: “… until they are self-governing and until they give their own award, preferably a degree, they will not be accorded at home or abroad the respect and status which they deserve”. Mr Wales's clear presentation of the points in the argument highlights the CATs' difficulties in having to work with carefully designed and built-in status disadvantages.
